Description

FIELD OF THE INVENTION

[0001] The present invention is generally directed to a connection assembly for coupling a building element to a surface, and more particularly, a connection assembly for coupling a building to a surface while permitting services to pass between the surface and the building element.

BACKGROUND OF THE INVENTION

[0002] The illustrated embodiment of the present invention was developed to fulfill existing needs in the bathroom industry. More specifically, the illustrated embodiment of the present invention aids in fulfilling previously unsolved problems associated with the installation of shower enclosures and other partitioning (e.g., partitions and doors around showers, shower receptors (trays) baths and spas, etc.) and problems associated with the varying installation practices of different countries and regions.

[0003] For instance, the U.S. and European markets follow substantially different sets of trade practices for the installation of bathroom structures, such as shower receptors, in each of the markets. One particular difference is how the plumbing and waste outlets are routed to the shower receptor and enclosure in each of the markets. In Europe, the norm is for all plumbing and waste pipes to be installed above floor level. A removable access panel is usually provided which allows access to the underside of the receptor for the connection of services such as plumbing and drainage.

[0004] In contrast, the U.S. market generally routes plumbing and waste conduits within the floor itself, meaning that waste pipes, etc. are cast or positioned within the floor. The U.S. methodology reflects a preferred installation of a shallow shower receptor with the sill or front skirt directly on the floor, acknowledging a consumer desire for the step into the shower enclosure to be as low as possible. There is no access panel as is used in the European market. This alternate form of installation also results in significant differences in the type of waste traps and how the various plumbing is routed and connected. The shallow nature and limited access under the receptor makes it difficult for subsequent tradesmen to attend to the connection of plumbing elements (under the receptor or within recesses on its underside) once the receptor has been installed. This problem becomes apparent when considering the commonly practiced procedure for shower installation in the U.S. and a number of other countries.

[0005] A typical procedure for a U.S. installation follows the sequence delineated below:

(i) the builder roughs out the position of the receptor and installs the receptor;

(ii) the plumber connects the waste and terminates the supply plumbing (behind the wall);

(iii) the builder completes the shower installation, including installing wet-wall linings and sealants;

(iv) the tiler tiles the enclosure; and

(v) the plumber returns to complete all remaining plumbing (in front of the wall).

[0006] The initial installation of the receptor makes it difficult for subsequent tradespersons who may not be present at that time. With such a high involvement of different tradespersons it becomes difficult to ensure the cooperation necessary to provide for the timely and professional installation of shower enclosures. This also imposes limitations on what is achievable, particularly for design considerations affecting the routing and connection of associated plumbing within the installation.

[0007] The greater access associated with European design and practice eases the requirements for cooperation between the varying tradespersons. This practice is opposed to many other countries, such as the United States, where tradespersons tend to perform their specific tasks individually and somewhat independently. Accordingly, for the U.S., it is not unusual for the tradesperson installing the partitioning and attending to the final connection of plumbing to arrive on site at the stage where the wall finishing (for wall and comer showers) are in place, and the shower receptor or flooring (e.g., showers with tiled floors) are also substantially completed. Any plumbing at this stage is virtually restricted to provided holes in the wall rather than on the underside of the receptor or through the floor.

[0008] A difficulty which also presents itself to the tradesperson is how to erect fittings such as supporting columns, elements, and other fixtures without damaging or dismantling substantially finished surfaces. Attempting to fix vertical members to a floor has been a difficult task and usually results in a visible mechanical connection, or increasing reliance to be placed on overhead or wall connections. Furthermore, many mechanical attachment techniques make the basal routing of plumbing to such vertical members virtually impossible or impractical and for this reason the routing of plumbing to vertical elements (which may contain horizontally directed body sprays) is almost exclusively from overhead or wall outlets. Attempts to route plumbing under shallow shower receptors sitting on the floor also present difficulties as it is difficult to subsequently connect and redirect such plumbing to vertical elements which can duct the plumbing to where needed. Market preference is directed towards as shallow a tray as possible, so as to avoid a step up into the shower, and hence problems associated with routing plumbing hidden under a tray is becoming more of an issue.

[0009] There are thus a number of problems facing the industry. These problems include:

• Providing a connection system for vertical elements and members which is substantially hidden or invisible after installation;
• Providing a connection system which allows for the accurate positioning and placement of vertical or other elements, particularly for attachment to finished or partly finished surfaces;
• Providing a connection system which readily allows for plumbing or other services to be routed to within, and connected to, the element or member;
• Providing a connection system which allows for connection of the element or member in a quick and easy fashion;
• Providing a connection system which affords some mechanical strength and resists disconnection;
• Providing a connection system which allows the element or member to be connected to a variety of different surfaces and finishes including (but not restricted to) metal, porcelain (both solid ceramic and coated), plastic, laminate, composite, tile, cement, masonry, various types of wall partitioning, suitable bath tubs, shower receptors, etc.; and
• Providing an easy to use system which allows for the basal routing of plumbing under structures such as shower receptors or base surrounds and to redirect this up into subsequently attached vertical elements.

[0010] Thus, there exists a need for a connection system which allows for the substantially trouble free installation of varying supporting elements and members associated with structures, some suitable examples being shower and bathroom structures, and which optionally may also include allowance for the connection and routing of plumbing or other services. There also exists a need for a connection system suitable for use on finished surfaces.

[0011] It is therefore an object of the present invention to consider the above problems and provide at least one solution which addresses a plurality of these problems. Ideally the present invention will also provide a connection system which allows for the substantially trouble free installation of varying supporting elements and members associated with shower and bathroom structures, and which optionally may also include allowance for the connection and routing of plumbing and other services. Ideally the connection system is suitable for use on finished surfaces.

GENERAL DESCRIPTION OF THE INVENTION

[0012] Further objects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only.

[0013] A number of terms will be referenced within this specification. It is known that different countries adopt different terminology for common items. This is particularly true in the building and construction trade, and for this reason the following glossary is given to more precisely define the intentions of the applicant with regard to these terms.

Glossary Of Terms Used

[0014] The following definitions are provided for certain terms and phrases used in this application. These definitions are provided solely for convenience, and should not be construed to provide a meaning having a scope less than would be understood by a person of ordinary skill in the art.

cam portion	an element having features which can interact to engage with a complementary engaging portion in such a way as to impede the longitudinal movement of the cam portion in relation to the complementary engaging portion.
cam fixture	the cam portion when fixed to a surface or structure.
building element	an element which one wishes to attach to a structure or surface. The building element may include of more than one component and therefore can include an assembly of components. The element may be hollow. For many applications the building element may be a post or like component for use in a shower cubicle or partition. It may sometimes be a horizontal member such as a rail or part of an overhead support structure. The building element may also have various associated components and services pre-installed or pre-assembled thereto.
hollow member	an element which has a cavity or channel for optionally housing services, such as plumbing, wiring, etc. Hollow members may form part of bathroom (or like) structures such as bath, spa and shower enclosures. These may be of varying cross-sections (i.e. their shape may not be constant along their length), and may have circular, oval, "D", "C", "U", or other shaped cross-sections. The cavity or channel may extend only partly or substantially fully along the length of the hollow member. The member may be a closed hollow member (where only access to the cavity is via the ends) or an open hollow member where the cavity may be accessible at other points along the length of the hollow member. More specifically, open hollow members may not be completely closed along their whole length and may have "C", "U", "V", or other shaped cross-sections. The open hollow members may interact with other walls or elements to further close the cavity once installed. As mentioned above, the cavity may also be present only along part of the length of the member, the member being solid or filled at other points. Preferably,
	the hollow portion is present at least one end where connection to the cam portion is to be made.
plumbing	an enclosed structure for conveying a fluid. Plumbing may include pipes and conduits for carrying water, air, waste, or other fluids, such as pipes for conveying water to be supplied to jets, nozzles, faucets, shower roses, etc.
plumbing connector	a device for coupling plumbing in fluid communication with another device. A plumbing connector may include elbows and junctions. Many different types of plumbing connectors are within the spirit and scope of the above definition, including push-fit and quick-connect type devices, such as John Guest push-fit connectors. Preferably the plumbing connectors allow for at least partial rotation of the plumbing connector after connection, permitting rotation of the cam portion and its complementary engaging portion during installation of the building element to the surface.
engage by partial rotation	engagement in which there is included, as part of the action required, a rotational action. By partial is meant that rotation is only part of the relative movement of the engaging portions when they are brought together and set to an engaged position. A preferred example of partial rotational engagement is the bayonet type action defined below. Preferably the relative rotation is less than 360°.
bayonet type action	in a bayonet type action there is both linear and rotational components in the relative movement of the engaging members when they are brought into proximity and set into an engaged position that resists at least longitudinal or linear withdrawal. There are three preferred forms of bayonet type action suitable for use with an embodiment formed in accordance with the present invention. The first is a 'flat bayonet action' where overlapping components of the engaging components only start to overlap with each other when rotation occurs after linear
	positioning. The second is the typical 'light bulb type' bayonet action where a guide element substantially prevents or limits relative rotation until linear positioning is completed. The third type is a 'helical bayonet action' in which rotation introduces a linear component to the relative movement of the engaging portions - such as drawing one portion down into the other. Reference is made to drawings later herein depicting the three preferred forms of bayonet type action.
translational movement	a linear or sliding movement, as opposed to a rotational movement. The bayonet action can be described as action having both translational movement and rotation movement components.
at the end	in proximity to an end of an object. Typically this term is used in relation to the annular attachment portion disposed 'at the end' of the hollow member or building element. In this context, 'at the end' means provided in a manner allowing the hollow member to be connected at its end to a surface or other object. The annular attachment portion may therefore be fixed or formed on the end of the hollow member (and thus be visible from outside) or housed internally within the member such that it is not externally visible. Hence 'at the end' should be read to mean 'at or near the end'.
annular attachment portion	is an element or assembly which is preferably annular or ring like in overall appearance, but need not necessarily be so. The term annular is used to functionally describe the fact that this portion engages about the cam portion. Sleeves and hollow cylinders fall within the definition. An annular attachment is a subset of the term 'engaging portion'.
Whirlpool	in some countries being a generic term which includes jetted baths with an associated pump for air and/or water, and in some
	countries referred to as a spa. The terms 'whirlpool' and 'spa' will be taken to be equivalent when used herein.

The method additionally includes installing a service conduit for passing a service between the building element from a point below the surface to a point within the building element. The service conduit passes through the first and second engaging portions such that the service conduit is hidden from view when the building element is coupled to the surface.

[0059] One embodiment of a method for attaching a building element forming part of a shower assembly and housing plumbing to a support surface performed in accordance with the present is provided. The method includes fixing a first engaging portion and a plumbing connection to the support surface. The method further includes connecting a complementary second engaging portion to one end of the building element. The method additionally includes installing plumbing within the building element with an end portion moveable outward from the building element to allow for connection of the plumbing to the plumbing connection fixed to the surface. The method further yet includes bringing the end of the building element into proximity with the first engaging portion and connecting the end portion of the plumbing to the plumbing connection. The method still further yet includes coupling the first and second engaging portions in a quick to connect manner to couple the building element to the surface.

[0060] One embodiment of a method performed in accordance with the present for attaching a building element of a shower assembly to a support surface, the building element housing plumbing, is provided. The method includes fixing a first engaging portion to the support surface and fixing a first plumbing connection to the support surface. The method further includes attaching a complementary second engaging portion capable of interlocking with the first engaging portion on the building element. The method additionally includes providing the plumbing within the building element with an end portion which is substantially rigid and fixing a second plumbing connection to the end portion. The method still further includes positioning the second engaging portion of the building element over the first engaging portion coupled to the support surface. The method also includes rotating the building element for interlocking the first engaging portion with the second engaging portion, wherein the positioning and rotating action also results in connection of the first and second plumbing connections to one another.

[0061] One embodiment of a method performed in accordance with the present invention of installing a shower enclosure which includes one or more building elements, wherein the building elements house plumbing associated with the enclosure, and wherein the building elements are coupled to a base structure, is provided. The method includes positioning and fixing to the base structure a cam portion for attaching the building element to the base structure. The method further includes bringing an end of the building element into proximity to the cam portion and connecting the plumbing housed within the building element to a plumbing connection associated with the base structure. The method additionally includes affixing the building element to the cam portion by engagement of a complementary engaging portion present at the end of the building element with the cam portion.

[0062] One embodiment formed in accordance with the present invention may be described as a connection system comprising engaging portions, one of which portions is associated with a member to be attached to a surface or structure, and the other portion attachable to said surface or structure (which may be during or post-construction depending on the embodiment), and which portions preferably interact and engage with a partial rotational (and preferably bayonet type) action.

[0063] In one embodiment formed in accordance with the present invention, the connection arrangement is substantially hidden, except by user choice, when the member is ultimately attached to the surface or structure by engagement of the portions. Preferably one portion can be considered a cam or cam-like arrangement which interacts with the second portion which can be likened to an annular sleeve. The components are preferably hollow or have removed portions to allow plumbing or services to pass from the surface (or structure) through to the building element being attached and which element may be pre-plumbed and/or pre-wired.

[0064] One method performed in accordance with the present invention provides for the attachment of a member or element to a surface, and preferably in a manner where the means of attachment or fastening is substantially hidden. The method will typically also be suitable for use in applications where there is limited or no access to the interior or underside of the existing surface or structure to which the element or member is to be attached-such as when the surface has been finished. Preferably the method also allows for the option of fixing, casting, or integrating components associated with the method into the surface (or underlying structure) at the time of surface preparation or finishing, as well as providing embodiments which will allow for implementation of the method to an already finished or substantially finished surface or structure.

[0065] One method performed in accordance with the present invention includes a method for the attachment of a building element, which may be substantially hollow, to an existing surface. Typically such building elements may comprise a support element, with one preferred type of support element constituting a vertical supporting member for a shower or bath enclosure, and to which other panels may be attached. However, preferred embodiments also include the instance where substantially free standing elements are provided. Quite often these elements or members are substantially vertical in orientation though the present invention also includes instances where these may be inclined (with respect to the vertical), or horizontal.

[0066] Embodiments of the present invention preferably utilizes interacting 'cam' and 'annular' engaging portions to effect a connection. In preferred embodiments, the annular portion is associated with the building element while the cam portion is associated with the surface structure at the point of attachment (of the building element). It is, however, envisioned that this association can be reversed such that the cam portion could be associated with the element, and the annular engaging portion with the surface or structure. The same principles of interaction and general design as discussed within this specification are applicable. It is considered that the skilled tradesperson, when armed with the description herein, will be able to implement such reversed embodiments of the invention from the description of the preferred embodiments. Accordingly, for simplicity and to avoid confusion, the remainder of the specification will largely refer to orientation of the preferred embodiments.

[0067] Preferred embodiments of the invention make use of a cam portion which, in the normal method of performing the method of the invention, is attached to the surface to which the building element is to be attached. The method of fixing is typically by either or both mechanical and adhesive fastening. Mechanical fastening methods include screwing, bolting, and various equivalents and alternatives thereof. A variety of suitable construction adhesives are known and these may used instead of, or in conjunction with, other mechanical fastening means. As a further variation, the cam portion may be formed, integrated, or cast into the surface at the time of its construction. For instance, a modified cam portion may be used which is positioned into cast concrete flooring. This may include a suitable anchor portion which is embedded in the concrete. It may also include distancing means so that the engaging portion of the cam is positioned above the floor surface. This may also take into account any floor finishing, such as tiles, which may be subsequently laid or put into place before attachment of the hollow member or element.

[0068] The cam portion will typically, in addition to means for fastening to the surface, include an engagement portion which can be disc-like in configuration, or include a central body portion with outwardly extending features or projections. This disc or body portion may also include removed portions which extend to or from the periphery of the disc or body. Apertures may also be provided within the disc or body, though this will be discussed later with reference to allowing services to pass through the cam portion. In other variations, multiple disc-like or repeating body portions may be provided and these may also have similar or dissimilar configurations. It is envisioned that the provision of two or more axially displaced co-axial disc-like or repeating body portions can improve the strength of the resulting attachment of the building element to the surface, though such an arrangement will typically also increase fabrication costs.

[0069] Preferably the disc-like (or alternate configurations) of the engagement portion will be positioned away from the surface to allow engagement with the attachment end of the building element to occur. Such spacing may be provided in a number of manners, including the provision of one or more stem portions, spacers, and/or body features. Whether services are to pass through the cam portion will also influence the specific body design.

[0070] In summary, most cam portions according to preferred embodiments of the present invention will include an engagement portion, which is preferably disc-like in appearance (though may have removed portions), an affixment portion allowing it to be affixed to the surface, and a spacing portion which distances the engagement portion from the surface. Other features may be provided including positioning pins, features, or faceted indentations to allow for the more ready alignment and/or positioning of the cam portion with respect to the surface. This becomes particularly important for cam portions used for the attachment of pillars which may have features present for the attachment of glass panels or doors. In this case, accurate alignment of the cam portion (which will also influence the rotational alignment of the attached member) is as important as the correct positioning of the cam portion on the surface.

[0071] It should be appreciated that the cam portion may comprise a single piece, or be constructed of separate components. The cam portion may be made of a number of materials including suitable plastics, metals, and composites which typically have properties of stiffness and rigidity, as well as strength commensurate to the task. Resilience is not normally a requirement except where this forms part of or contributes to the prevention of or resistance to rotation of the attached element with respect to the cam portion, or to resisting its removal therefrom. A certain amount of resilience in some components can also allow for greater tolerances in manufacturing, with deformation by component resilience compensating for too tight a tolerance. However the preference is for accurate and precise manufacturing.

[0072] An engaging portion is provided to interact with the cam portion. This may be a separate element or elements attached to the building element to be subsequently connected, or alternatively formed into the building element during its fabrication. When separately attachable engaging portions are provided, adaptors may be provided to allow its attachment to a hollow end portion of building elements of different internal configurations. This will increase the versatility of the present invention, and thus allow a single cam and insert (engaging portion) set to be used on a variety of differently configured hollow member building elements. Any means of attaching the engaging portion to the building element (including mechanical fastening, adhesive fastening and/or mechanical interaction between parts) should ideally be hidden from exterior view.

[0073] In the context of the present invention, the building element (to be attached) may only be hollow in the vicinity of where engagement with the cam portion occurs. In this case the remainder of the member may be solid or filled. However, for the types of applications provided herein, provision needs (in most cases) to be made for services such as plumbing, electrical wiring, etc., to pass through the attachment arrangement and also the building element to be attached. This will be discussed in more detail later.

[0074] Typically the engaging portion (associated with the building element) will substantially encircle the cam portion when fitting and attachment occurs. Accordingly the engaging portion may be sleeve like, with the sleeve often being represented by the interior wall of an insert, or the interior wall of a hollow member building element itself. Typically inwardly directed features are provided on the inward face of the engaging portion to interact with removed portions in the engaging portion of the cam.

[0075] For most embodiments of the present invention, the preferred method of attachment results from a partial rotational, and preferably bayonet type, action between the engaging portion and cam portion. More specifically, this represents axial sliding of the engaging portion over the cam portion, followed by subsequent partial rotation. After rotation, features on the engaging portion and/or cam portion interact (usually overlap) to prevent the two portions from becoming axially separated. If removal is allowed, then a reversal of the bayonet type fitting action will be required. In preferred embodiments however, rotation resisting features may be provided to prevent or resist one or more of these actions. A variety of rotation resisting mechanisms are known in the trade, including detent, ratchet, and similar mechanisms. One or more of these may be employed (for instance) to help lock the engaged component, or to resist release and separation.

[0076] When multiple disc-like or repeating body portions are provided on the cam portion, it is possible that the partial rotational action may be provided in respect of all the disc-like or repeating body portions. However, it is also possible that some of the disc-like and repeating body portions may not necessarily so engage. Instead they may merely serve to increase the relative strength of the attachment, so as to resist pivoting of the building element about the cam portion by increased surface contact between the components (at different points along the length of the member).

[0077] Accordingly, in preferred embodiments of the present invention, there is provided a cam portion which is fixable to a surface, and an engaging portion which may be inserted or formed into a building element. The two portions may be engaged through, preferably, a bayonet type action which involves relative sliding and rotation of the member (and associated engaging portion) over the cam portion. Providing that the engaging portion is suitably positioned within the interior of the building element to be attached, the result is an attached member with virtually no, or substantially no, visible evidence of the connection arrangement except by user choice.

[0078] Modifications may also be made to the arrangements of the invention such as by the provision of seals to help seal the base of the building element against the ingress of water or foreign material. These seals may be substantially invisible, or intended to be visible, in the attached assembly. These may be separate annular type members which are positioned over the cam portion (like a washer) prior to the attachment of the building element. Alternatively these may also form part of the cam portion.

[0079] Other cam portions may be configured so that the building element to be attached will, instead of being substantially perpendicular to the surface to which the cam portion is attached, be aligned at a predetermined angle to the perpendicular. This increases the versatility of the system, and the manner by which it may be used. These variations are also likely to find more use for the attachment of the building element to walls, and vertical and inclined surfaces other than just floors. An adjustable unit in which the resulting angle can be adjusted by movement and subsequent locking or tightening of the component is within the spirit and scope of the present invention.

[0080] It is envisaged for most applications that plumbing or other services will need to be routed to a wall or floor structure (to which the cam portion is to be attached) and to the building element. In this case, the building element is typically substantially hollow along its length to allow the provision of internal plumbing and services. The problem which is then introduced is how to allow for these services (or plumbing) to pass through the attachment arrangement, and also how suitable connections (for the plumbing or type of services) can be made in situ at the time of attaching the building element. Ideally this attachment should not interfere with the substantially hidden nature of the arrangement once the building element is attached. Further, the method of attachment of the services and plumbing should not interfere with the attachment mechanism and be able to cope with a bayonet type attachment operation. Most preferably, the arrangement should also be able to cope with situations where the building element may be pre-wired, or pre-plumbed, etc. However, not all embodiments of the present invention take into account this option. Some variations of the present invention which deal with these issues will now be discussed.

[0081] Embodiments of the present invention are adaptable to allow services to pass from an existing structure ( or below a surface) to within the building element to be attached. While this could be accomplished in a number of ways, the preferred arrangement is to provide an aperture or removable portion allowing various services (including plumbing) to pass through the cam portion. This may be accomplished by the provision of one or more apertures in the engagement portion and any appropriate portions of the cam portion. Slots and removed portions are also possible. Removable 'knock-out' portions may also be provided so that the apertures are only present when required.

[0082] In a preferred embodiment there is a substantially centrally positioned aperture through which plumbing from the existing structure/surface can penetrate. This should be of sufficient dimension to allow the appropriate plumbing and/or other services to pass through. In practice, for plumbing, a cut off section of the pipe may protrude from the surface to which the building element is to be attached. The cam portion can then be positioned over this cut off portion of pipe. Ideally the aperture and/or other removed portion of the cam should be larger than the outside diameter of the pipe. This will allow some provision for movement of the cam portion with respect to the pipe so that the cam portion can be precisely positioned and located, even if the pipe is not.

[0083] Typically at the next stages the pipe will be terminated with an appropriate fitting or modification made to allow the plumbing from within the member to be connected. It is also possible that the suitable terminating connector can be integrated into the cam portion so that other plumbing from the member may be directly connected to the cam portion itself. However, not all types of plumbing, plumbing connection systems, and situations may allow this particular variation. It is envisioned that more often than not (currently) a separate connector piece will be attached to the free end of the cut off pipe section.

[0084] Typically next, the connecting end of the building element will be brought into proximity to the cam portion which by now should have been secured to the surface. Taking the case of a pre-plumbed element, it is desirable that the internal plumbing can be extended free of the end of the building element so that connection can be made with the terminated plumbing associated with the cam portion. This is especially true for connection systems which may require a tool such as a spanner to complete the connection. However, there are also quick-to-connect and push-fit connection systems available which may be employed with the present invention. Providing suitable guidance, for alignment of the various components, is provided such that it is possible that adequate connection of plumbing sections can be completed by merely pushing the building element over the cam portion in order to complete the bayonet fastening arrangement. In such cases it will not be necessary to pull the internal plumbing section free of the end of the building element. However it is generally desirable that some visual confirmation of a secure connection can be made and thus it is envisioned that this would not normally be a preferred embodiment except where visible inspection and/or adjustment can be made through the wall of the building element itself. This is not a desirable arrangement as it complicates the fabrication process for the member, and also disturbs the aesthetics and smooth finish of most elements used in bathroom structures.

[0085] In one embodiment formed in accordance with the present invention, the plumbing is free to extend beyond the connecting end of a pre-plumbed building element. The modification is preferably made to facilitate such extension but to also allow withdrawal back into the building element once the connection (of the plumbing) is completed and the element is attached to the cam portion. This can be achieved by providing a coiled and extendable section of plumbing which can be pulled free from the connecting end of the building element to allow attachment to the pipe section associated with the cam portion. This extending section of plumbing is preferably of a resilient plastic material, though it may be metal, and ideally have a natural bias such that the coils are in close proximity or touching each other when in a rest state. Examples of such plastics are coiled air-line hoses used in spray painting and with air driven tools. These can be suitably modified and may be appropriate (e.g., using the appropriate materials to convey hot, cold, or mixed/tempered water) for use with plumbing code compliance and standards.

[0086] Various types of connection systems including various types of quick-to-connect systems, though more conventional threaded systems can still be employed when using extendable pipe embodiments of the present invention.

[0087] Also included within the present invention are modified building elements such as previously described and/or for use in conjunction with cam portions such as described herein. These include hollow members which are hollow primarily at or near the connection point to the cam portion only to fully tubular structures. Both closed and open structures are envisioned, with open structures including tubular members with removed portions which may extend along only part or all of the length of the member.

[0088] It is also envisioned that the building elements need not be straight and long and may also include curved and variously configured arrangements, including pre-assembled structures.

[0089] Building elements intended to house one or more elements, one suitable example being a building element housing plumbing and services, and those which house nothing, may be used and are included within the scope of the present invention. Those which carry services may be pre-plumbed, or pre-wired, etc. Various types of connection systems may be used for services other than plumbing. The same principles as described above for plumbing may be used though with connection systems for other types of services. It is envisioned that most other services than plumbing will be of an electrical nature and will tend to (in a bathroom situation) constitute power sources, or control signal sources for associated equipment such as thermostats, flow control, heating devices, sensors, manual or electronic control switches, etc.

[0090] Construction of a bathroom structure such as a shower enclosure can proceed, when aspects of the present invention are employed, in a number of manners. It is envisioned that embodiments of the present invention can cater to the various types of installation procedures adopted and performed throughout the world, as the system does not require access to the interior or underside of the surface itself providing the various services clear the surface or are otherwise accessible for connection. Accordingly, embodiments formed in accordance with the present invention are suitable for retrofitting as well as being integrated at an earlier stage of construction. It is also envisioned that the majority of embodiments allow for connection substantially without tools, or minimum tools, which simplifies the secure attachment of members to cam portions which have already been fastened to the surface. If the cam portions are, in case of a shower enclosure, installed at the factory (i.e., pre-plumbed) then the time taken by the plumber to install such plumbing is substantially eliminated, and the subsequent erection of the members is simplified. This makes it very easy for subsequent trades people, or the resident, to subsequently install various building elements and/or structures. It is envisioned that embodiments of the present invention may also be used for mounting other articles within the house, and particularly where provision for the introduction of services must be made at the attachment point.

[0091] It is also envisaged that the cam portion may be modified to interact with shower receptors, bathtubs, and bases for other structures, etc. These receptors and components may be fabricated to include suitable mounting points for a cam portion according to the present invention. These may also include locating lugs, facets, or recesses which complement lugs, facets, and recesses which may be provided on the cam portion. This can help the secure and precise placement of the cam portions, as well as ensuring their correct orientation - particularly when other components (such as shower doors and panels) are to be fitted at precise orientations to the member attached to the cam portions.

[0092] A preferred embodiment of the present invention ideally realizes one or more of the features listed below. Various embodiments may realize different combinations or other features than those listed following:

1. The engaging portion referred to as a cam is preferably attached, connected, or integrated with the supporting surface (e.g., floor, wall, shower receptor, bath tub, etc.);

2. The engaging portion referred to as the cam preferably has more than one flange portion which at least engages complementary features on the other engaging portion;

3. The engaging portions interact with a bayonet type interaction;

4. The rotation for engagement is preferably less than 360°;

5. There is preferably resistance to rotation or disengagement once the engaging portions have been coupled;

6. The engaging portions have a provision for the passage of plumbing and services therethrough;

7. Once the engaging portion referred to as the cam has been fastened or otherwise affixed to the supporting surface, preferably hidden plumbing and services are accessible from the exposed face(s) of the cam engaging portion;

8. In pre-plumbed building elements, preferably the connecting of plumbing is through a pull down section or plumbing or services which can be extended from the building element for connection to plumbing or services associated with the alternate (affixed) engaging portion to be made;

9. The pull down section of plumbing or services is preferably biased to retract to within the building element;

10. The connection of the engaging portions is substantially hidden from view in the connected arrangement;

11. The arrangement preferably allows for both accurate vertical and horizontal positioning of the building element, and stability of connection with respect to movement in the vertical and horizontal directions, and preferably also against pivoting from the vertical about the connection point; and

12. The engaging portion referred to as the cam portion is preferably a separate component (or assembly), though it may also be designed to be an integral component of the supporting surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0094] Although embodiments of the present invention are described as implemented with regard to shower systems, one skilled in the relevant arts will appreciate that the disclosed connection assembly and the disclosed embodiments are illustrative in nature and should not be construed as limited to application with regard to shower systems. It should therefore be apparent that the connection assembly has wide application, and may be used in any situation where connecting two objects together while permitting services to pass therethrough is desired.

[0095] FIGURES 1 and 2 illustrate one embodiment of a shower assembly 200 formed in accordance with the present invention. Generally stated, the shower assembly 200 includes plumbing 204 and 206 for transferring shower water from a water source (not shown) to a nozzle 33, wherein the plumbing 204 and 206 is hidden from view below a surface 13 and within a building element 30, to which the nozzle 33 is attached. The shower assembly 200 includes a connection assembly 202 which permits the coupling of the building element 30 to the surface 13 in a quick connect manner while permitting the plumbing 204 and 206 to pass hidden from view between the surface 13 and the building element 30 through the connection assembly 202.

[0096] Focusing on the plumbing 204 and 206, the plumbing 204 and 206 may be subdivided into an upper portion 204 associated with the building element 30 and a lower portion 206 associated with the surface 13. The lower portion includes a supply pipe 2 terminated in a plumbing fitting 1. The plumbing fitting 1 is a standard flanged terminating elbow as is commonly used within wall cavities and other structures for supplying water to subsequently attached fittings. Cooperating with the plumbing fitting 1 is a threaded adapter 3 which threads into a threaded female portion 4 of the plumbing fitting 1. Disposed at the top end 5 of the threaded adapter 3 is an appropriate fitting 208 for connecting to a connector 6 of the upper portion 204 of the plumbing. Preferably the threaded adapter 3 couples to the connector 6 of the upper portion 204 of the plumbing in a quick-to-connect arrangement, one suitable example being what is known in the trade as a JOHN GUEST® fitting. The threaded adapter 3 is generally fitted to the plumbing fitting 1 prior to installation of the other components.

[0097] Although specific fittings are described and illustrated for coupling the upper portion 204 and the lower portion 206 of plumbing in fluid communication with one another, it should be apparent to those skilled in the art that any number of coupling systems may be utilized for coupling the upper and lower portions 204 and 206 to one another and are therefore within the spirit and scope of the present invention. A few suitable examples of alternate coupling methods include coupling a connector 6 upon the upper section that is adapted to rotate upon the distal end of the upper portion 204 such that a set of external threads of the connector 6 may directly engage the internally threaded female portion 4 of the plumbing fitting 1, thereby eliminating the need for the adapter 3. Further, the upper and lower portions 204 and 206 may be a continuos unbroken section of piping, passing between the surface 13 and the building element 30 without the need of connectors.

[0098] The upper portion 204 of the plumbing will now be discussed in greater detail. The upper portion 204 of the plumbing includes a flexible section 34 of pipe and a rigid section of pipe 7 coupled to one another via a plumbing connection 210. Coupled to a distal end of the flexible section 34 of pipe is the connector 6 for coupling to the threaded adapter 3 as described above. The flexible section 34 of pipe is selectively extendable, expandable, and/or adjustable in overall length such that the connector 6 may be moved longitudinally relative to the building element 30. Preferably, the flexible section 34 is adjustable in length such that the connector 6 may be moved longitudinally into an extended position wherein the connector 6 is at least partially disposed outward of the building element 30, as shown in FIGURE 1. In the extended position, the connector 6 may be accessed by the user to couple the connector 6 to the threaded adapter 3 prior to the coupling of the building element 30 to the surface 13 via the connection assembly 202.

[0099] Preferably, the flexible section 34 is biased to pull the connector 6 from the extended position to a retracted position, wherein the connector 6 is at least partially disposed within the building element 30 as shown in FIGURE 2. Thus, when the building element 30 is coupled to the surface 13, the connector 6 and flexible section 34 are automatically withdrawn into the building element 30. This ensures that the connector 6 and flexible section 34 are out of the way of the building element 30 and the surface 13, and therefore do not interfere during the coupling of the building element 30 to the surface 13. In the illustrated embodiment, the flexible section 34 is a flexible coil of plastic tubing, however it should be apparent to those skilled in the art that other types of sections of piping adapted to extend in length are within the spirit and scope of the present invention, one suitable example being a telescoping section of pipe.

[0100] The rigid section of pipe 7 is affixed to the building element 30, and therefore does not move relative to the building element 30. The rigid section of pipe 7 passes through a central cavity 212 of the building element 30, delivering water to at least one control device, some suitable examples of control devices being fixed or handheld roses, mixing valves, faucets, and spray nozzles 33, which are plumbed within the building element 30.

[0101] This detailed discussion will now focus upon the connection assembly 202. The connection assembly 202 generally includes a locking member, a receiving member, or a cam portion 10 which interlocks with a locking member, an interference member, or an engaging portion 20. The cam portion 10 in the illustrated embodiment is coupled to the surface 13 and the engaging portion 20 is coupled to the building element 30. The cam portion 10 may be selectively engaged with the engaging portion 20 to couple the building element 30 to the surface 13 in such a manner as to at least resist the longitudinal movement of the building element 30 relative to the surface 13, i.e., to resist their separation.

[0102] Still referring to FIGURES 1 and 2, the cam portion 10 includes a passageway, open center, or substantially hollow interior 11. The hollow interior 11 is sized and configured to permit the threaded adapter 3 to be moved longitudinally through the hollow interior 11. Attached to the cam portion 10 is an alignment mechanism, such as a locating pin 12. The locating pin 12, which may be broken free when not required, helps the correct positioning and/or alignment (rotationally) of the cam portion 10 during fitting. More specifically, the locating pin 12 is adapted to cooperatively interact with an alignment device, such as receiving apertures 214 disposed in the surface 13 and the plumbing connection 1.

[0103] The cam portion 10 is affixed to the surface 13, which may represent a floor structure, lip or mounting point on a shower tray, bath tub surround, or a variety of other anchoring surfaces. Mechanical fasteners 14 are used to fasten the cam portion 10 to the surface 13 and/or the plumbing connection 1. An adhesive sealant may additionally be used around the base of the cam portion 10 as normal trade practice dictates.

[0104] The cam portion 10 is disc-like in appearance. The cam portion 10 includes outwardly extending protrusions or flange portions 15 disposed at the top of the cam portion 10. Preferably they are outwardly extending flange portions 15 which interact with similar protrusions or flanges 23 on the engaging portion 20.

[0105] This detailed description will now focus upon the engaging portion 20. The engaging portion 20 is shown already attached to the building element 30. The building element 30 may have cross-sections which may vary according to user choice, a few suitable examples of cross-sections within the spirit and scope of the present invention include "O", oval, "D", "C", "U", and "V", as well as cross-sections which varying along the height of the building element 30. In the illustrated embodiment, a circular cross-section profile is described and illustrated for simplicity.

[0106] Bolts or other mechanical fasteners 21 are used to secure the engaging portion 20 to the building element 30. In the illustrated embodiment, the mechanical fasteners 21 engage a pair of u-shaped screw pipes 31 disposed on the inside wall of the building element.

[0107] Raised portions, such as locating tabs 32 may be provided to help position and locate the building element 30 with regard to the engaging portion 20. Preferably, the locating tabs 32 are located such that the locating tabs are disposed within the central cavity 212 of the building element 30 when the building element 30 is attached to the surface 13, such that the locating tabs 32 are hidden from view. It should also be noted that although in the illustrated embodiment the engaging portion 20 is sized and configured such that the engaging portion is sandwiched between the building element 30 and the surface 13 and visible after installation, it should be apparent to those skilled in the art that connection assembly 202 may be modified slightly so that once connected, the engaging portion 20 is recessed entirely (and hence fully hidden) within the building element 30 and/or the surface 13.

[0108] The engaging portion 20 of the illustrated embodiment is annular in shape and includes a passageway, open center portion, or central aperture 22 to permit the plumbing 204 and 206, and/or other services, such as electrical services, to pass therethrough. Extending radially inward into the central aperture 22 are flange portions 23 which are sized and configured to cooperatively interact with the flange portions 15 associated with the cam portion 10, thereby interlocking the cam and engaging portions 10 and 20 to one another.

[0109] In light of the above discussion of the structure of the shower assembly 200, the installation of the shower assembly 200 will now be described. First, the plumbing fitting 1 is coupled to the cam portion 10 via fasteners 14, thereby sandwiching the surface 13 between a flange of the plumbing fitting 1 and the cam portion 10. The alignment pin 12 is disposed within the alignment apertures 214, thereby ensuring that the cam portion 10 is correctly aligned relative to the surface 13 and/or the plumbing fitting 1. A seal 36 may be disposed in a recess 232 in the engaging portion 20 so as to aid in impeding contaminants, such as water and debris, from entering the shower assembly 200. The threaded adapter 3 is screwed into the threaded female portion 4 of the plumbing fitting 1.

[0110] The next step in the method of installation is to couple the engaging portion 20 to the end of the building element 30 via fasteners 21. Then the connector 6 is withdrawn from the building element 30 and coupled to the complementary shaped end piece 5 of the threaded adapter 3. The building element 30, with its associated plumbing 204 and engaging portion 20, may then be lowered downwardly over the cam portion 10. The building element should be positioned (i.e., rotated) so that the flanges 23 of the engaging portion 20 do not interfere with the flanges 15 of the cam portion 10 as the assembly is being lowered upon the cam portion 10. Moreover, the flanges 23 of the engaging portion 20 should be aligned with clearance cuts (i.e. the open spaces 250 (see FIGURE 8) in the cam portion 10 permitting the flanges 23 of the engaging portion 20 to pass between the flanges 15 of the cam portions 10) such that the flanges 15 and 23 may be linearly moved past each other.

[0111] Once lowered, the building element 30 is rotated so that the flanges 23 of the engaging portion 20 engage the flanges 15 of the cam portion 10 in an overlapping relationship, interlocking the cam portion 10 with the engaging portion 20 as shown in FIGURE 2 . This arrangement impedes the building element 30 from being removed from the cam portion 10, while permitting the passage of the plumbing 204 and 206 between the surface 13 and the building element 30. The arrangement results in the coupling of the building element 30 securely to the surface 13 with no externally visible evidence of attachment and of the plumbing 204 and 206 running therethrough.

[0112] It can be appreciated the method of attachment is very simple once the cam portion 10 has been fastened to surface 13, and engaging portion 20 has been fastened to the building element 30. It is envisaged that the coupling of the engaging portion 20 to the building element 30, and the cam portion 10 to the surface 13 will preferably be completed at an earlier stage by the various trades persons, or during the manufacturing and assembly process of the shower assembly 200 for pre-plumbed embodiments. When the plumber or resident is ready to finally erect the building element 30, all that is required is the simple coupling of the connector 6 to the threaded adapter 5, and a bayonet type fitting action of the building element 30 to the cam portion 10. This arrangement makes installation substantially easier in the instance where not all trade persons are present on site at the same time. The use of fitting templates for the accurate positioning of the cam portions 10 can also facilitate the ease of installation for trade persons present at earlier stages, and ensure a more accurate subsequent fitting of components during final erection of a shower enclosure, partitioning, etc.

[0113] FIGURE 3 illustrates an alternate embodiment of a connection assembly 300 formed in accordance with the present invention. The connection assembly 300 of FIGURE 3 is substantially similar in operation and construction to the connection assembly 202 depicted in FIGURES 1 and 2, with a couple of exceptions. Therefore, for the sake of brevity, this detailed description will focus on the features which deviate from the previously described embodiment.

[0114] Generally stated, the connection assembly 300 of FIGURE 3 differs from the embodiment of FIGURES 1 and 2 in that the flexible section 34 of pipe of FIGURES 1 and 2 has been replaced with a rigid section 334 of pipe. Further, the threaded adapter 3 of FIGURES 1 and 2 has been replaced with a quick connect or push connect fitting 303. Likewise, the threaded female portion 4 of FIGURES 1 and 2 has been replaced with a quick connect or push connect fitting 304 selected to cooperatively couple in fluid communication with fitting 303 in a quick connect manner.

[0115] In operation, the connection assembly 300 is configured such that it is possible that adequate connection of plumbing sections can be completed by merely pushing the building element 330 over the cam portion 310 in order to complete the bayonet fastening arrangement. In contrast to the embodiment of FIGURES 1 and 2, in the embodiment of FIGURE 3, it will not be necessary to pull the internal plumbing section free of the end of the building element 330. Since it is generally desirable that some visual confirmation of a secure connection be made, it is envisioned that this connection assembly 300 would be preferably used in situations where visible inspection and/or adjustment can be made through the wall of the building element itself.

[0116] Although a rigid and straight piece of pipe is used to form the rigid section 334 of pipe in the illustrated embodiment, it should be apparent to those skilled in the art that other forms of the rigid section 334 are within the spirit and scope of the present invention. For instance, copper tubing formed in a helical manner as depicted in FIGURES 1 and 2 may be used, such that the helical shape of the rigid section 334 acts as a stiff spring, slightly biasing the push connect fitting 303 towards the corresponding push connect fitting 304 to aid in the coupling of the fittings 303 and 304 to one another while allowing for some tolerance to handle some miss-alignment of the fittings 303 and 304.

[0117] Referring to FIGURE 4, an alternate embodiment of a connector assembly 260 formed in accordance with the present is provided. The connector assembly 260 includes an engaging portion insert 216 which can be positioned and held within the building element 30. The building element 30 shown in FIGURE 4 includes barbs 37 disposed on an interior wall of the building element 30 which interact with cooperatively shaped recesses 248 disposed in the engaging portion insert 216 to help maintain the insert in place. A plurality of such interacting features may be used to help retain the engaging portion insert 216 in position. Other fixing and fastening methods may also be considered and are within the spirit and scope of the present invention.

[0118] In FIGURE 4, the cam portion 10 also includes a base 50 which helps tidy the end of the building element 30. The base 50 rests on the surface into which the cam portion 10 is cast. Downwardly extending anchors 49 are embedded into the floor to secure the base 50 in place when the floor is cast. A washer type seal 36 may be used to provide a seal between the base 50 and the building element 30.

[0119] FIGURE 5 is a detail view of a flange 15 of the cam portion 10 interacting with a flange 23 of the engaging portion 20 of the embodiment depicted in FIGURE 4. Of note, the inwardly directed flange 23 is provided on an interior wall 29 of the engaging portion insert 216 as best shown in FIGURE 4. These interacting flanges 15 and 23 are suitable for use with the embodiments described in FIGURES 1-3. Visible on each flange 15 of the cam portion 10 is a downwardly directed projection 40. Assuming for illustrative purposes, rotation of the building element (and thus the engaging portion 20) in a clockwise direction for fitting and securing of the building elements upon the cam portion 10, the leading edge 41 of the flange 15 may be inclined while the trailing edge 42 is substantially perpendicular to the bottom face of the flange 15. As can be appreciated, this ratchet type design will resist anti-clockwise turning should projection 40 extend into a recess 43 such as is shown on the flange 23 of the engaging portion 20. Similarly, one face 44 of the recess 43 is substantially vertical to resist anti-clockwise turning once the projection 40 is present within the recess 43. This provides a rotation resisting function resisting subsequent rotation and removal of the attached building element 30 and its associated components. As should be apparent to those skilled in the art, the leading and trailing angles can be varied to suit the requirements of the user. For instance, the height and angle of the leading and trailing angles can be varied such that once the cam portion 10 is interlocked with the engaging portion 20, the cam portion 10 is in a fully locked arrangement with the engaging portion 20, such that cam portion 10 is substantially permanently coupled to the engaging portion 20.

[0120] Even where a rotation resisting provision is not made, the provision of interacting features (such as projection 40 and recess 43) may be desirable to help ensure the correct degree of rotation during assembly. Other methods including stops and raised end projections (on the flange portions and elsewhere within the various components) may also be considered to achieve the same effect so as to ensure that connected components end up in the correct rotational position.

[0121] FIGURE 6 illustrates another embodiment of the cam portion 10 formed in accordance with the present invention. The cam portion 10 of FIGURE 6 includes multiple disc-like portions for further impeding the building element 30 from pivoting with respect to the cam portion 10. This embodiment is used in situations where a stronger or more rigid coupling of the building element 30 to the surface is desired. In the illustrated embodiment, in addition to the disc-like portion 54 of the cam portion 10, an additional disc-like portion 55 is provided. This upper disc-like portion 55 may include outwardly extending flanges (not shown) which also interact with inwardly directed flange portions on the building element 30 or its insert. In the embodiment of FIGURE 6, no such features are provided, with the outer periphery of the upper annular disc-like portion 55 configured to bear against the inside wall of the building element 30. Removed portions extending inwardly from the periphery (not visible in the diagram) should be provided to permit the flange portions on the engaging portion to travel past.

[0122] Still referring to FIGURE 6, the building element 30, which has not been completely lowered into place, is depicted to illustrate how the outer periphery of portion 55 bears against the inside of the building element 30. It can be appreciated that the two points of contact further stabilizes the arrangement and helps prevent pivoting of the building element 30 with respect to the cam portion 10.

[0123] As a variation, the upper disc-like portion 55 and a separating body portion 56 may be removable/attachable to lower disk-like portion 54. This may be by means of a threaded or other arrangement. It is further possible that additional elements 58 (disc-like portion 55 and/or separating body portion 56) may be stacked sequentially one upon the other to extend the height of the cam portion 10 and thus alter its relationship with the building element 30.

[0124] FIGURE 7 illustrates one embodiment of an engaging portion 20 formed in accordance with the present invention and suitable for use with the embodiments of FIGURES 1-3. As can be seen, the primary body 70 of the engaging portion is substantially annular in appearance. Three inwardly extending flange portions 23 are present and again positioned to correspond with the position of the flanges 15 associated with the cam portion 10.

[0125] Centering tabs 72 are disposed on the upper face of body 70 to correctly position the wall of the building element 30 (see FIGURE 1). Apertures 73 are provided for fasteners 21 to pass through and secure the annular engaging portion 20 to the building element. Open hollow tubular features of substantially "C", "U", or "V" (other shapes can be considered) cross section are provided on the interior of the building element into which the fasteners 21 may be screwed.

[0126] The various components associated with the present invention may be constructed from different materials. Metals may be used, though metals that are preferably corrosion resistance are preferred. Materials such as aluminum and its alloys, various stainless steels, bronzes and brasses, etc., may all be employed. They may be fabricated by casting, machining, combinations of both, and/or by other suitable manufacturing processes. Such materials may be utilized for the cam portion and associated components, the engaging portion and associated components, as well as the building element.

[0127] Other materials may also be considered. Plastic materials are especially suitable and again, many are known which are suitable for casting, machining, and for various other fabrication techniques. High impact thermoplastic materials may be considered for use. Materials worthy of consideration include many nylons, polyurethanes, as well as composite materials, and resin based materials.

[0128] Seals and washers, if provided, may be manufactured from normally utilized materials for these types of components. Sealant materials (e.g., caulks, etc.) may also be used.

[0129] The building element may be substantially constructed of one or more components, with the same choice of materials as the cam and the engaging portions described above. However, other materials may also be considered, as well as different fabrication techniques. Where the building element is of substantially constant cross section, extruded lengths and sections may be considered. In the preferred embodiment of FIGURE 1, the building element is an extruded section of aluminum, though it may be formed from an alternative material, such as discussed above.

[0130] FIGURE 8 illustrates a bottom perspective view of the cam portion 10 depicted in FIGURE 7. FIGURE 8 illustrates the annular shaped main body 60 of the cam portion 10 and the outwardly extending flanges 15 of the cam portion 10. The flanges 15 each include a distension, tooth or protrusion 218 which engages a cooperatively shaped detent or recess disposed in each of the flanges of the engaging portion to impede rotation of the engaging portion relative to the cam portion 10 in the unlocking direction. A limit stop 220 associated with each flange 15 impedes additional rotation in the locking direction of the engaging portion relative to the cam portion 10 once the two portions are in the engaged/locked position. Apertures 61 allow for fastening screws or bolts to pass therethrough.

[0131] In FIGURE 8, the central portion 63 has a removable plate 230 which may be punched or knocked out should it be necessary to pass services therethrough. As can also be seen, the flanges 15 are distanced from the main body 60 of the cam portion 10 by a selected distance 64. This allows for the flange portions of the engaging portion to be positioned underneath, and also to compensate for the thickness of any seals which are used during installation.

[0132] Three outwardly extending flange portions 15 are shown, though other quantities are suitable for use with and within the spirit and scope of the present invention, including quantities greater or less than three. While these may be spaced equidistantly about the periphery, non-equidistant spacing may be preferable to ensure that the attached member can only be positioned and attached in a single angular orientation. This will help prevent building elements being fitted in incorrect orientations, a particular problem where hinges, jets or supports are provided on the building element.

[0133] FIGURE 9 illustrates one embodiment of a capping member 222 formed in accordance with the present invention. The capping member 222 is a further variation of the previously described cam portions. Some building elements formed in accordance with the present invention will have a top or alternate end which may be open. If this is to be capped, it may be desirable to accomplish this without visible connection means. FIGURE 9 illustrates one embodiment of a capping member 222 which may be used to cap the opening. The capping member 222, in its simplest form, represents substantially a cam portion such as illustrated in FIGURE 1 (as item 10) though without locating pin 12. Fastening apertures 61 (see FIGURE 8) may not be present either. Flange portions 82 (corresponding to flanges 15 in FIGURE 1) are also provided on the main body 81 of the capping member 222. An aesthetically pleasing and appropriate cover piece 83 is provided on the ultimate end of the body 81, which would normally be the end which would contact the floor or surface 13 in FIGURE 1.

[0134] The building element (not shown for simplicity in FIGURE 9) would also be modified to include an engaging portion with which the capping member 222 can interact. Accordingly, substantially the same component may, with minimal (or no) modification, be used for fixing the building element to a surface, as well as for capping/closing an open end of the building element.

[0135] An alternate embodiment of a capping member 224 formed in accordance with the present invention is shown in FIGURE 10. The alternate embodiment depicted in FIGURE 10 is substantially identical to the embodiment depicted in FIGURE 9, with the exception that the cover piece 83 is separable from the primary body 81 of the capping member 224. In this arrangement, an internal aperture 84 of the capping member 224 is threaded to allow the cap 83 to be screwed in by virtue of its projecting stem piece 86. In this arrangement, the primary body 81 may also serve as a capping portion and therefore can be used at either or both ends of the building element. As a further variation, the internal aperture 84 of the primary body 81 need not be threaded, but instead, the downwardly directed stem portion 86 can be configured to allow an interference fit, or another type of connection to maintain the cover piece 83 in place.

[0136] FIGURE 11 illustrates an arrangement utilizing the internally threaded cam portion 81 of FIGURE 10. If two of these threaded cam portions 90 and 91 are connected by a threaded tube or rod 92, the result is a connector enabling two sections of building element to be quickly connected to one another. This increases the versatility of the cam portion and allows it to be used in a number of manners.

[0137] FIGURE 12 illustrates an embodiment of the cam fixture 100 which may be used for connecting building elements at an angle to the surface 13. Here the main hollow body portion 101 is inclined at an angle to the main base portion 102, which is also configured to seat the base of the building element. These embodiments may be available in a variety of angles to suit different types of construction of enclosures, which will compensate for surfaces at different angles from the perpendicular or horizontal. Some angles (measured with respect to the surface) may be relatively shallow (e.g., 1.5 to 5 degrees) and thus these fixtures may compensate for natural inclines in the surface for water drainage. In other instances they may be configured to follow the contour of an irregular or non-planar surface mounting position. This is likely to be where the cam portion is not fixed to a wall or floor, but to a tray, tub, or installed article.

[0138] FIGURE 13 illustrates, in a conceptual schematic form, the preferred types of bayonet action discussed earlier. FIGURE 13A illustrates the 'flat bayonet action' where overlapping components of the engaging components only start to overlap with each other when rotation occurs after linear positioning. FIGURE 13B represents the typical 'light bulb type' bayonet action where a guide element substantially prevents or limits relative rotation until linear positioning is completed. FIGURE 13C represents a 'helical bayonet action' in which rotation introduces a linear component to the relative movement of the engaging portions - such as drawing one portion down into the other.

[0139] While the preferred embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention substantially as defined in the appended claims.

[0140] It should also be understood that the term "comprise" where used herein is not to be considered to be used in a limiting sense. Accordingly, 'comprise' does not represent nor define an exclusive set of items, but includes the possibility of other components and items being added to the list.

[0141] This specification is also based on the understanding of the inventor regarding the prior art. The prior art description should not be regarded as being an authoritative disclosure of the true state of the prior art but rather as referring to considerations in and brought to the mind and attention of the inventor when developing this invention.
