Description

TECHNICAL FIELD

[0001] The invention relates to the field of insulating glass applications, preferably for use in a glass frame with multiple glazing. The glass frame may be used in a sliding door system, such as with a balcony, veranda or terrace. In particular, the invention provides a glass spacer for a glass frame. The invention furthermore provides a glass frame for a sliding glass door. The invention furthermore provides a sliding glass door for a sliding door system. The invention furthermore provides a sliding door system. The invention furthermore also relates to a method for assembling the glass frame, sliding glass door and/or sliding door system.

TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] Traditional sliding door systems for a terrace or a veranda consist of a stationary outer frame which surrounds two or more sliding glass doors. At least one sliding glass door is configured to be movable in the outer frame. The sliding glass doors are preferably placed one behind the other, so that it becomes possible to slide one set of doors in the horizontal direction with respect to the other doors. This makes it possible to achieve a considerable space saving compared to, for example, French windows.

[0003] In recent years, there has been an increase in demand for minimalistic sliding door systems, in which the external surface of the often large frame is reduced to a minimum. In addition to a desired aesthetic aspect, this also leads to an improved incidence of light in the dwelling. However, increasing the ratio of the glass to the frame means that the thermal conduction (typically indicated by means of a U value and a psi value) and strength of the system will substantially depend on the glazing and the exact positioning thereof in the sliding glass doors.

[0004] The use of multiple insulating glazing (such as double glazing, low-emission glass or triple glazing) yields considerable advantages for the insulating capacity of such sliding door systems. In order to limit the formation of condensation and also to reduce the heat loss of the edge zone, a glass spacer is fitted between the glass panes, as a result of which every glass pane is in fact clamped between, on one side, a glass spacer and, on the other side, a profiled section of the sliding glass door. There are various types of thermally improved glass spacers (also referred to as 'warm edges') on the market, ranging from stainless steel or aluminium profiled sections to combinations of plastic embodiments.

[0005] Irrespective of the choice of glass spacer, the installation of the glass frame is always carried out according to the same method. First, a primary connection between the glass spacer and the glass panes is produced, for example, using a Thiokol cord, which serves to keep the glass panes together. Then, a secondary sealing is produced, for example using silicone or Thiokol paste, which mainly serves to seal the created cavity from the open air, so that the gas which has been introduced cannot escape. Because a glass frame is very fragile, in particular its sides, a protective window frame is fitted around the glass panes and fastened thereto. Fastening may be effected, for example, by adhesively bonding a panel or profiled section over the glass panes, to which a window frame may be click-fitted.

[0006] Since the window frame is fixed beforehand, there is then no possibility to carry out further adaptations to the length and width of the frame during installation of the sliding door system on a building site. In addition, the outer frame has to be glued perfectly perpendicular to the glass during production, which is not always the case because of the large dimensions for sliding glass doors.

[0007] During installation at a building site, a sliding glass door as such is relatively unstable and has to be anchored to an external structure, such as an outer frame of the sliding door system. Typically, anchoring is effected by forming a groove in the fixing means, for example, a Siltal-joint, or in the glazing itself. This joint is subsequently filled with an anchoring point which can be coupled to a structure situated behind it. In other words, the glazing is mechanically clamped against the profiled sections in the width direction of the glass frame, that is to say perpendicular to the glass. However, a perpendicular anchoring coupling results in a loss of space between the glazing and the sliding glass door, as well as next to the frame, due to the presence of the anchoring element itself. In addition, if the dimensions on site differ from the building plans, a correct alignment of the glazing is difficult due to the fact that the sliding glass door has been fixed beforehand. For example, it is not possible to make any adaptations in the plane of the glazing because this would interrupt the sealing, resulting in inadequate thermal insulation and the formation of condensation. This may result in a superfluous opening in the central seal (i.e. the free between the glass frame and the profiled sections of the window frame). This may have negative consequences for the stability of the system in the longer term and thus requires a very accurate production and adaptation to the building plan, as well as user-friendly settings in order to ensure satisfactory operation of the sliding door system.

[0008] In addition, a sliding door system comprises a sliding system which makes it possible to slide at least one sliding glass door in the length direction of the outer frame. Typically, a sliding means is fitted between the sill of the outer frame and the bottom side of the sliding glass door to be moved. This sliding system is adjusted during installation of the sliding door system in order to render sliding as smooth as possible. However, in many dwellings, in particular in newly built dwellings, the surrounding structural elements may move, such as the walls, also referred to as the "settling" of the walls, the ceiling and/or the floor. This will in turn also have an impact on the operation of the elements of the sliding door system. Due to the fact that the sliding system was adjusted on the basis of the position of the sliding glass doors and the outer frame at the time of installation, the sliding system may therefore start to slide less smoothly after some time. Currently, there are no ways to absorb or compensate for such displacements after installation. There is therefore a need for a system which offers a solution for one or more of the above problems.

Unless defined otherwise, all terms disclosed in the invention, including technical and scientific terms, have the meaning which a person skilled in the art usually gives them. For further guidance, definitions are included to further explain terms which are used in the description of the invention.

[0058] The invention relates in a first aspect to a glass spacer for a glass frame with multiple glazing, the glass spacer comprising: a widened component for forming a cavity between at least two glass panes and an elongate component for lateral protection of the (sides of the) at least two glass panes.

[0059] In a further aspect, the invention relates to a glass spacer and anchoring element for adapting a central seal between a glass frame and a window frame of a sliding glass door; the glass spacer comprising a widened component for forming a cavity in the glass frame; an elongate component for lateral protection of the glass frame; and, an anchoring component configured for lateral coupling to the anchoring element; wherein the anchoring element is configured for lateral coupling of the glass frame to the window frame; and wherein the glass spacer and the anchoring element are configured to adjust the size of the central seal by adjusting the lateral coupling in between.

[0060] In a further aspect, the invention relates to a glass frame with multiple glazing for a window, for example, a sliding glass door, the glass frame comprising: at least two glass panes and at least one glass spacer according to one or more embodiments such as described herein.

[0061] In a further aspect, the invention relates to a window, for example, a sliding glass door for a sliding door system, the window comprising: a glass frame according to one or more embodiments as described herein; and a window frame comprising one or more profiled sections for the housing of the glass frame.

[0062] In a further aspect, the invention relates to a sliding glass door for a sliding door system, comprising: a glass frame provided with a glass spacer configured for lateral coupling of the glass frame; a window frame for housing or surrounding the glass frame; an anchoring element for lateral coupling of the glass frame to the window frame; and, wherein the sliding glass door is configured to adjust the size of a central seal between the glass frame and the window frame by adjusting the lateral coupling thereof.

[0063] In a further aspect, the invention relates to a sliding door system, for example, for a balcony, veranda or terrace, the sliding door system comprising: at least two sliding glass doors according to one or more embodiments as described herein; and an outer frame comprising one or more profiled sections for housing the at least two sliding glass doors; wherein at least one sliding glass door is configured to move in the length direction of the outer frame.

[0064] Multiple glazing refers to the presence of several glass panes, usually configured to run parallel to each other. These glass panes are kept separated by a glass spacer which preferably maintains a uniform separation and determines the width of the gap between the glass panes. This free space is referred to as the cavity. The cavity may be filled with air to form an air cavity or with a gas, such as argon, which ensures improved thermal performance. The cavity may also be vacuum-drawn. In addition, one or more glass panes may have an additional coating or metal layer, preferably on the side of the cavity, which also results in an improved thermal performance. Examples of multiple glazing are double glazing, low-emission glass, triple glazing, etc. With regards to multiple glazing, the invention is not limited to a certain number of glass panes and can easily be adapted to include a higher number of glass panes.

[0065] The "U value", expressed as W/(m².K), is the linear heat transmission coefficient which indicates the heat loss across the window, measured from the inside to the outside, per meter at a temperature difference between the inside and the outside of 1°K. The U value is therefore an indicator for the heat loss via the front and rear side of the insulating glass and frame. The U value may be determined by means of a measuring installation or may be calculated in accordance with DIN EN 674.

[0066] The "psi value" (ψ), expressed as W/(m.K), is the linear heat transmission coefficient which indicates the heat loss at the contact surface window-glass-spacer per meter at a temperature difference between the inside and outside of 1°K. The psi value is thus an indicator for the heat loss via the side of the sliding glass door, via the glass spacer. The psi value may be determined by means of a measuring installation or may be calculated in accordance with DIN EN 674.

[0067] The invention as described herein has various advantages with respect to the prior art. Firstly, the glass spacer according to the present invention provides lateral protection of the sides of the glass panes. The sides of the glass panes are the weak points of the glass frame. Even little damage to a side of a glass pane, for example during installation or transportation, can lead to cracks which can spread throughout the entire glass pane. The body of a conventional glass spacer is limited to a component which is fitted between glass panes in order to form a cavity. It offers no protection to the glass panes, as a result of which the glass frame requires a robust frame.

[0068] The lateral protection by the glass spacer according to the invention ensures that there is no need for a clamping frame which securely clamps both the front, rear and sides of the glass panes. Consequently, the surface area of the window frame around the glass frame can be considerably reduced compared to a conventional window frame. In particular, in certain cases, the portion which runs over the fronts of the glass panes can be limited to the glass edges. In this way, the glass spacer makes it possible to construct minimalistic door sliding systems which greatly increase the amount of incident light and improve the aesthetics.

[0069] Furthermore, a glass spacer according to the present invention can make it possible to improve the gastightness and airtightness of the cavity. With a conventional glass spacer, the sealing is limited to the space in the cavity, formed at the sides of the glass spacer. The glass spacer according to the present invention makes it possible to seal the sides of the glass pane as well, as a result of which the sealing can be much more comprehensive and accurate. An improved sealing results in improved airtightness which may improve the heat insulation of the device and may reduce the formation of condensation. In addition, a lateral sealing is also less fragile during installation and can still be repaired if damage thereto is limited, something which is not possible with conventional glass spacers.

[0070] Finally, a glass spacer according to the present invention makes it possible to reduce the heat loss of the glass frame or window. The improved sealing and protection of the cavity makes it possible to fit the glass spacer less "deeply" inside the cavity, that is to say at a smaller distance from the side of the glass panes. As a result thereof, the size or volume of the glass spacer can be limited. The body of the glass spacer has a higher thermal conduction than the cavity between the two glass panes and a reduction in the size or volume of the body of the glass spacer can thus immediately result in an improvement in the psi value of the sliding glass door.

[0071] The glass spacer comprises a body which comprises at least two structurally different and separate components, namely a widened component and an elongate component. Optionally, the body of the glass spacer comprises a third component, in particular an anchoring component.

[0072] The body of the glass spacer may be made of a polymer, composite or metal. A polymer glass spacer may be made of rubber or PVC. A metal glass spacer may be made of aluminium or alloys. In addition, a glass spacer can also be made of a combination of materials. Each material has its advantages and disadvantages which are assumed to be known by the person skilled in the art.

[0073] The body of the glass spacer may consist of several interconnected components, but preferably consists of one cohesive unit. The components may be made of the same or different materials. The body is preferably made by means of a (co-)extrusion process so as to be able to make the various components from the most suitable material. Alternatively, the components of the glass spacer body may also be made individually and be attached to each other subsequently, for example using a bonding means, such as glue.

[0074] The widened component serves to form a cavity between the glass panes of the multiple glazing. The edges of the widened component are suitable to come into contact with the innermost surface of the at least two glass panes, in particular the front or rear side of glass panes and the widened component which will form the walls of the cavity.

[0075] The contact between a glass pane and the widened component may be a direct contact, in which the widened component is placed against the front of the glass pane. The contact between a glass pane and the widened component is preferably an indirect contact, in which a sealing means or coating layer is provided between the surface of the widened component and the glass pane.

[0076] The widened component is preferably virtually gastight, that is to say that no exchange of gas can take place through the widened component. Grooves or ridges may be provided in the surface of the widened component which make it possible to compress the component more efficiently. This may, for example, result in an improved sealing of the cavity.

[0077] The widened component may be flexible, for example made of plastic. A flexible widened component is able to absorb pressure which is exerted on the glass panes. This pressure may be caused, for example, by a knock against a glass pane, or vibrations when sliding a sliding door open or shut, or by thermal expansion and shrinkage. The widened component may be rigid, for example made of metal such as aluminium. A rigid widened component may result in improved airtightness.

[0078] The widened component may be virtually beam-shaped. The cross section of the widened component may then virtually form a quadrangle, preferably a rectangle. The widened component may furthermore have a wide side and a narrow side. The cross section of the widened component may then virtually form a hexagon. The wide side may then form a quadrangle, preferably a rectangle, and the narrow side may form a trapezoid, preferably an isosceles trapezoid. The narrow side may form a narrowing which merges into the elongate component or the anchoring component. The presence of a narrowing may have advantages with regard to the sealing and/or thermal conduction of the glass spacer (comprising a decrease in the psi value of the sliding window).

[0079] The widened component may have a width of at least 1.0 mm up to at most 30.0 mm; preferably 2.0 mm to 29.0 mm; preferably 3.0 mm to 28.0 mm; preferably 4.0 mm to 27.0 mm; preferably 5.0 mm to 26.0 mm; preferably 6.0 mm to 25.0 mm; preferably 7.0 mm to 24.0 mm; preferably 8.0 mm to 23.0 mm; preferably 9.0 mm to 22.0 mm; preferably 9.0 mm to 21.0 mm; preferably 10.0 mm to 20.0 mm; for example 11.0 mm; for example 12.5 mm; for example 15.0 mm; for example 17.5 mm; for example 19.0 mm. The width of the widened component is the distance between the two opposite sides which will be in contact with the glass panes and preferably run parallel with the glazing in order to form the cavity. The person skilled in the art will appreciate that the width of the widened component can be adapted to suit the desired width of the glass frame, for example to adapt the size of the cavity.

[0080] The widened component may have a length of at least 1.0 mm up to at most 10.0 mm; preferably 2.0 mm to 9.0 mm; preferably 3.0 mm to 8.0 mm; preferably 4.0 mm to 7.0 mm; preferably 5.0 mm to 6.0 mm; for example 5.5 mm. The length of the widened component is the distance between the two opposite sides which are or will be in contact with, on one side, the cavity and, on the other side, the components of the glass spacer (elongate component or anchoring component); in the length of the glass frame or the cavity. The person skilled in the art will appreciate that the length of the widened component can be adapted to suit the desired sealing of the glass frame, for example to provide more sealing means.

[0081] The widened component may comprise a moisture-absorbing material or desiccant. This may further reduce the condensation in the cavity by improving the absorption of moisture. The moisture-absorbing material is inserted in the widened component, preferably in a free space provided inside the widened component. Examples of moisture-absorbing materials are desiccant granules and silica gel granules.

[0082] The widened component may comprise a gas sealing means. Preferably, the gas sealing means will be attached to or fitted on a side of the widened component. In a preferred embodiment, the gas sealing means will be attached to or fitted on a wide side of the widened component, in which the wide side is preferably in contact with the free space of the resulting cavity. This may further reduce the gas exchange in the cavity which may produce improved thermal properties and reduce condensation. An example of a gas sealing means is a metal foil, such as an aluminium foil.

[0083] The elongate component serves to cover the glass panes of the multiple glazing laterally. The walls of the elongate component are thus suitable to be in contact with the lateral surface of the at least two glass panes, in particular with the side of the glass panes which are in contact with the rectangular component. The contact between a glass pane and the elongate component may be a direct contact, in which the elongate component is fitted over the sides. The contact between a glass pane and the elongate component is preferably an indirect contact, in which a sealing means or coating layer is provided between the surface of the elongate component and the glass pane.

[0084] The elongate component is preferably virtually gastight, that is to say that no gas exchange can take place through the component. Grooves or ridges may be provided in the surface of the elongate component which make it possible to increase the contact surface; this may, for example, result in an improved lateral sealing.

[0085] The elongate component may be rigid, for example made of rigid plastic. The elongate component may be flexible or rigid, for example made of a flexible plastic. A flexible widened component can be fitted over the glass panes more easily, but still has to be sufficiently rigid to provide a sufficient degree of protection.

[0086] The elongate component may comprise one or more branches. The branches make it possible to fit the elongate component over the corners of a glass pane and/or to cover the roundings on the side of the glass pane. Optionally, the branches may be provided with tear or cutting strips to cut the branches if they are too long.

[0087] The elongate component may comprise an opening and/or insertion strip for inserting the anchoring element. As a result thereof, it will be easier to couple the anchoring element to the body of the glass spacer.

[0088] The elongate component may have a length of at least 1.0 mm up to at most 100.0 mm; preferably 5.0 mm to 95.0 mm; preferably 10.0 mm to 90.0 mm; preferably 15.0 mm to 85.0 mm; preferably 20.0 mm to 80.0 mm; preferably 25.0 mm to 75.0 mm; preferably 30.0 mm to 70.0 mm; preferably 35.0 mm to 65.0 mm; preferably 40.0 mm to 60.0 mm; for example 42.0 mm; for example 45.0 mm; for example 50.0 mm; for example 55.0 mm; for example 60.0 mm. The length of the elongate component is the distance between two opposite sides which run parallel with the glazing. This preferably corresponds to the distance between the front or rear side of a first glass pane to the front or rear side of a second glass pane, which distance is bridged and covered by the elongate component. The person skilled in the art will appreciate that the length of the elongate component can be adapted to the desired width of the glass frame, for example to cover wider glass panes.

[0089] In some embodiments, the elongate component has a width of at least 1.0 mm up to at most 10.0 mm; preferably 2.0 mm to 9.0 mm; preferably 3.0 mm to 8.0 mm; preferably 4.0 mm to 7.0 mm; preferably 5.0 mm to 6.0 mm; for example 5.5 mm. The width of the elongate component is defined as the distance between the two opposite sides, one side of which is in contact with the glazing; in particular from the first side which is in contact with the side of the at least two glass panes to the second side. The person skilled in the art will appreciate that the length of the elongate component can be adapted to the desired degree of protection of the sides of the glass frame. A wider elongate component will provide more protection, but will consequently also render the glass frame wider.

[0090] The anchoring component forms a coupling point for an anchoring element. The anchoring element is an external element which is coupled to the anchoring component and preferably remains coupled. The anchoring element may be a fastening means, such as a screw, a bolt, a nail, a hook, an anchor point and the like. The anchoring component may comprise a free space in which the anchoring element is inserted or fitted. In this case, the anchoring component will at least partly house the anchoring element.

[0091] The anchoring component may comprise a free space which is suitable for inserting the anchoring component. The sides of the free space or insertion strip may be provided with a threaded profile for screwing in a screw as an anchoring element. By providing an opening, the anchoring is made simpler since the screw does not have to create an opening in the body of the glass spacer. This may be advantageous with regard to the user-friendliness and installation speed. Preferably, the opening is adapted for screwing in a threaded screw. The anchoring component and/or the free space in the anchoring component may be adapted to suit the embodiment of the glazing and of the anchoring element. For example, if the glass frame is relatively substantial, there may be a need for thicker and longer anchoring elements, such as screws. The bridge between the widened component and the elongate component may thus be designed to be longer and wider in order to provide space for larger screws. Alternatively, if the glass frame is relatively small, a small bridge may be provided, so that the sliding glass door can be kept compact.

[0092] The coupling between the anchoring element in the anchoring component is preferably adjustable, it is preferably an adjustable coupling. An adjustable coupling makes it possible to adjust the degree of coupling. In particular, it will make it possible to adjust the depth of the anchoring element in the anchoring component. The coupling of the anchoring element in the anchoring component may be permanent, for example, by following the coupling with adhesive bonding. Adjustment is then only possible during installation. The coupling is preferably non-permanent, for example, only screwed in. This makes readjustment possible, for example after installation.

[0093] The anchoring element may be, for example a threaded screw, in which the coupling is adapted by screwing the screw into and out of the anchoring component of the glass spacer. For example, if the anchoring component is a threaded screw, then the length can be adapted by screwing in the screw or by unscrewing it.

[0094] The anchoring component may form or be a component of the widened component or of the elongate component, for example, as a thickening or branch. The anchoring component is preferably a separate part which is connected to the widened component and/or the elongate component. The anchoring component may form a bridge between the widened component and the elongate component. The bridge may be virtually beam-shaped, but may also have other shapes, such as cube-shaped, cylindrical, conical, etc. If the anchoring component forms a separate component in the body of the glass spacer, the widened component and the elongate component can be adapted more reliably with regard to their functions, as a result of which the glass spacer may provide a further improvement for the stability and strength of the protection of the glass panes.

[0095] The anchoring component may have different shapes, but is preferably adapted to the shape of the anchoring element. An opening may be provided in the anchoring component or this opening may also be formed during installation, for example, during or as a result of the coupling with an anchoring element. An opening may also be provided in the elongate component which offers access or a passage for the anchoring element to the anchoring component.

[0096] The anchoring component (in a bridge embodiment) may have a width of at least 1.0 mm up to at most 20.0 mm; preferably 2.0 mm to 19.0 mm; preferably 3.0 mm to 18.0 mm; preferably 4.0 mm to 17.0 mm; preferably 5.0 mm to 16.0 mm; preferably 6.0 mm to 15.0 mm; for example 7.0 mm to 14.0 mm; preferably 8.0 mm to 13.0 mm; preferably 9.0 mm to 12.0 mm; for example, 10.0 mm; for example, 11.0 mm. The width of the anchoring component (in a bridge embodiment) is the distance between two opposite sides which run substantially parallel to the glazing. The person skilled in the art will appreciate that the width of the anchoring component can be adapted to suit the desired sealing of the glass frame, for example, to provide more sealing means.

[0097] The anchoring component (in a bridge embodiment) may have a length of at least 1.0 mm up to at most 20.0 mm; preferably 2.0 mm to 19.0 mm; preferably 3.0 mm to 18.0 mm; preferably 4.0 mm to 17.0 mm; preferably 5.0 mm to 16.0 mm; preferably 6.0 mm to 15.0 mm; preferably 7.0 mm to 14.0 mm; preferably 8.0 mm to 13.0 mm; preferably 9.0 mm to 12.0 mm; for example 10.0; for example 11.0 mm. The length of anchoring component (in a bridge embodiment) is the distance between two opposite sides which are at right angles to the glazing. This preferably corresponds to the distance between the widened component and the elongate component. The person skilled in the art will appreciate that the length of the anchoring component can be adapted to suit the desired sealing of the glass frame, for example, to provide more sealing means.

[0098] The glass frame comprises the glass spacer described herein which is fitted between at least two glass panes. In this case, a glass pane refers to a pane of glass, such as typically known for a window. There are different variations of glass and glass finishes and the advantages and disadvantages thereof are assumed to be known by the person skilled in the art. The glass panes are preferably positioned substantially parallel with respect to each other.

[0099] The glass frame as described herein is more stable and more robust than a glass frame which contains only conventional glass spacers. In addition, the glass frame is held together along the sides by the combination of the glass spacer and the sealing means, as a result of which no external frame is required to produce sufficient stability to fit and transport the glass frame. As a result thereof, the glass frame can be assembled in situ on site, in contrast to assembly in a workshop. This makes it possible to take irregular parameters into account, for example due to mistakes during assembly.

[0100] The glass frame may also comprise a range of glass spacers according to one or more embodiments as described herein. A typical glass frame will comprise at least one glass spacer arranged on every side of the glass frame. However, the glass spacers according to one or more embodiments as described herein may be combined with conventional glass spacers.

[0101] The glass frame may, for example, comprise at least two glass spacers according to one or more embodiments as described herein, wherein the glass spacers are preferably arranged on either side of the glass frame. If only two glass spacers are present, the two sides will preferably form the left and right side of a sliding glass door in a door sliding system; this will make an anchoring in the length direction of the door sliding system possible. The other two sides, such as the top and bottom side, may be filled with conventional glass spacers.

[0102] The glass frame may, for example, comprise at least four glass spacers according to one or more embodiments as described herein, wherein the glass spacers are preferably arranged on each side of the glass frame. Such an embodiment can ensure that the cavity is correctly adapted in a more reliable manner and also facilitates the installation in the sliding glass door.

[0103] In the glass frame, the widened component of the glass spacer will be fitted or fittable between the at least two glass panes, and the elongate component of the glass spacer will be fitted or fittable over the sides of the at least two glass panes.

[0104] The widened component may be connected to at least one glass pane, preferably to at least two glass panes by a first sealing means. The first sealing means serves to seal the cavity in an airtight manner and to keep the glass panes connected to each other. The first sealing means may be a polymer; preferably an organic polysulphide polymer; more preferably Thiokol.

[0105] The elongate component may be connected to at least one glass pane, preferably to at least two glass panes, by a second sealing means. The second sealing means serves to seal the side of the glass frame in an airtight manner and to protect the side of the glass panes. The second sealing means may be a polymer; more preferably Thiokol or silicone. If desired, the first sealing means and the second sealing means may also be the same sealing means. Alternatively, the first sealing means and the second sealing means may be two different sealing means. For example, wherein the first sealing means is more rigid and in particular provides more reliable sealing of the cavity, and the second sealing means is more flexible and in particular provides improved protection of the glass edges. The sliding glass door comprises the glass frame described herein which is fitted in a window frame. The window frame comprises one or more profiled sections suitable for housing the glass frame. A profiled section as used herein refers to a rigid and preferably elongate body, typically used as a border of a frame. Depending on the desired embodiment, a profiled section may be both rounded and flat, having a wide or narrow wall, be hollow or filled on the inside with a filling material, may be ridged or smooth, and/orcomprise ornamental finishes; the advantages and disadvantages of the different embodiments of profiled sections are assumed to be known by the person skilled in the art.

[0106] The profiled sections are typically made of a rigid material. This may be, for example, metal, preferably aluminium. Aluminium has many advantages as a material for profiled sections, as it is not only robust and light, but at the same time readily able to withstand adverse weather conditions and requires little maintenance. However, other materials are also suitable and the advantages or disadvantages thereof are assumed to be known by the person skilled in the art.

[0107] The sliding glass door as described herein can be coupled laterally to the window frame. The lateral coupling is made possible by the fact that the glass spacer forms a projecting coupling part in the length direction of the glass frame to which the window frame can be coupled. The frame the glass frame securely clamps laterally against and/or to the glass spacer. Alternatively or additionally, the glass frame may be laterally connected to the window frame. The connection may be brought about by adhesive bonding or via an anchoring element, such as a screw. As a result thereof, the surface area of the window frame around the glass frame may be considerably reduced compared to a conventional sliding glass door. In particular, in certain cases, the portion which runs over the fronts of the glass panes can be limited to the glass edges.

[0108] The lateral coupling may make it possible to couple the glass frame directly to the window frame. As a result thereof, the installation may be more user-friendly, simpler and quicker. In addition, such a coupling produces a very stable and robust sliding glass door. In this way, the sliding glass door makes it possible to construct minimalistic door sliding systems which considerably increase the amount of incident light and improve the aesthetics.

[0109] For comparison, with conventional glass frames, a joint or groove is provided on the side of the glass frame, the fixing means or in the glazing itself. This joint is subsequently filled with a structural anchoring which can be coupled to a structure which is situated behind it and is at right angles to the direction of the cavity. With such systems, it is not possible to make adaptations in the direction of the cavity, for example, by screwing, as this is associated with the risk of breaking the gas and water barrier which is formed by the conventional glass spacer. As a consequence thereof, glass frames comprising only conventional glass spacers are coupled to structures situated behind them. However, using the glass spacer as described herein, it is possible to provide sufficient space in the elongate component with respect to the rectangular component in order to render an anchoring in the direction of the cavity possible. As a result thereof, it not only becomes possible to adjust the anchoring itself, but also to couple the glass spacer to an adjacent structure, such as the sliding glass door.

[0110] The sliding glass door as described herein can be coupled laterally to the window frame by coupling an anchoring element to an anchoring component of the glass spacer. The coupling is preferably an adjustable coupling. An adjustable coupling allows the degree of coupling to be adjusted. In particular, it will allow the depth of the anchoring element in the anchoring component to be adjusted.

[0111] A central seal may be formed between the glass frame and the window frame, the central seal being the free space between the window frame and the glass frame in the length direction of the sliding glass door. The adjustable coupling as described herein may allow adjustment of the central seal. In particular, the size of the central seal will be adjusted, that is to say the distance between the window frame and the glass frame. Preferably, the adaptation of the coupling takes place in the length direction of the sliding glass door. This adjustment may be carried out by changing the depth of the anchoring element in the anchoring component in the glass spacer.

[0112] The adjustable coupling may result in improved alignment of the glass frame with respect to the window frame and the outer frame. This not only leads to an improved aesthetic appearance, but also to more incident light. Alternatively, the alignment may also be adapted in order to hide certain faults or defects of the glass frame behind the window frame, if necessary. In addition, this adjustment may be carried out in situ on site, in contrast to assembly of prefabricated components and profiled sections which may adversely impact optimum installation if there are deviations. Consequently, the sliding glass door is simpler to use and may reduce the amount of planning, such as measuring to a very high degree of accuracy.

[0113] Optionally, the glass frame may be fixed to the window frame after the desired adjustment of the central seal. This may be carried out after installation on site. The fixing ensures that the desired alignment of the glass frame in the sliding glass door will be maintained for a relatively long period of time. The fixing preferably takes place by means of a fixing means, such as glue.

[0114] The sliding door system comprises the sliding glass door described herein which is fitted in an outer frame. The outer frame or casing comprises one or more profiled sections suitable for housing the sliding glass door. The sliding door system will comprise at least two sliding glass doors, at least one of which is like the sliding glass door described herein. Preferably, all sliding glass doors in the sliding door system will be sliding glass doors as described herein. At least one sliding glass door will be configured to move in the length direction of the outer frame.

[0115] The sliding door system as described herein can be more stable and more robust than conventional sliding door systems. In addition, the alignment of the sliding door system can be performed in a more satisfactory way. As a result thereof, the sliding door system allows more incident light, in particular for a minimalistic sliding door system in which the size of the profiled sections is reduced to a minimum. In addition, the sliding door system is not only easier and quicker to install, but it also makes it possible to compensate for certain production errors, such as differences in dimensions, due to the adjustability of the central seal.

[0116] The movement of the at least one sliding glass door may be a sliding movement, for example, by means of a sliding system. The sliding system is a system which allows the movement of at least one sliding glass door. The sliding system may in principle comprise different embodiments and the choice thereof does not, in principle, have an impact on the adjustability of the sliding system. Each sliding system has its advantages and disadvantages with regard to the slidability, rigidity, stability and service life and the advantages or disadvantages thereof are assumed to be known by the person skilled in the art.

[0117] By way of example, the sliding system may comprise a guide, wherein the guide is arranged on the outer frame. The use of a guide is currently the most popular form of sliding means. Preferably, the guide is a running track, which allows the sliding glass door to be displaced to slide over the running track. The sliding glass door may be provided with wheels which are able to move or roll over the guide. The use of wheels is currently the most popular form of sliding means. The wheels are usually fitted in the sliding glass door, but variations thereof are possible. The sliding system may also comprise several sets of wheels and/or rails.

[0118] The sliding glass door may rest permanently on the guide, but may also be disengaged, for example by a lift-sliding system, wherein the sliding glass door is lifted from the guide in the closed position, thus making sliding impossible. Alternatively, the guide may be a magnetic system which makes the sliding glass door float.

[0119] The sliding door system and/or the outer frame may also be provided with additional elements in order to increase the quality and the comfort of the sliding door system. By way of example, a dust or draught excluder may be provided which extends from the sill of the outer frame up to or against the upper wall of the outer frame to keep the glazing clean and to protect it. In addition, all kinds of sealings, rubbers and/or buffers may be added to make opening and closing and/or sliding the door easier for the user. In addition, all kinds of anti-burglary and safety means may be provided to improve the safety of the sliding door system.

[0120] The sliding door system may comprise an adjustable sliding system, the adjustable sliding system may comprise a sliding means configured to move at least one sliding glass door in the length direction of the outer frame; and a sliding profiled section coupled to the outer frame which frames and/or supports at least a part of the sliding means, wherein the sliding profiled section is height-adjustable. In this case, the height is the direction at right angles to the ground surface of the outer frame, for example on the bottom sill.

[0121] A height-adjustable sliding system may make it possible to adjust the sliding glass door to be displaced to the outer frame in a more satisfactory way during installation of the sliding door system, as a result of which sliding is smoother and simpler. In addition, the adjustable sliding system may make it possible to readjust the sliding glass door with respect to the outer frame as time goes by, for example after a structural displacement of the surrounding supporting elements, such as the walls, has taken place. This is usually the case in newly built dwellings, in which the sliding door system is installed before the dwelling has "settled". The adjustable sliding system is thus able to compensate for such displacements. This may ensure that the sliding door system can retain the original sliding characteristics which it had when first installed. This may improve the comfort and quality in use of the sliding door system over relatively long periods.

[0122] The adjustable mechanism of the sliding system is preferably arranged in a separate sliding profiled section which is coupled to the outer frame, for example by the bottom sill of the outer frame. This sliding profiled section may be permanently coupled, but may also be uncoupled in case replacement is required, for example in case there is damage or a defect. The adjustable mechanism can be adjusted by providing openings for adjusting screws in the tube under the sliding door guide.

[0123] The combination of an adjustable central seal and an adjustable sliding system may increase the service life and in particular the quality of the sliding door system over long periods after installation.

[0124] In a further aspect, the invention relates to a method for assembling a glass frame, the method comprising:

a) placing a widened component of a glass spacer between at least two glass panes;

b) connecting the widened component to the glass panes using a first sealing means;

c) fitting an elongate component of the glass spacer over the sides of the at least two glass panes; and

d) connecting the elongate component on the sides of the glass panes with a second sealing means.

[0125] This method has the advantage that assembling a glass frame can be simpler, more user-friendly and quicker. In addition, this method does not require the presence of an external frame or profiled section to securely clamp the glass pane. In addition, due to the fact that the sides of the glass frame are better protected, the method may result in a more stable and more robust glass frame, for example for installation or transportation of the glass frame.

[0126] In some embodiments, the first sealing means is a polymer, preferably an organic polysulphide polymer, more preferably Thiokol. In some embodiments, the second sealing means is a polymer, more preferably Thiokol or silicone. The first sealing means and the second sealing means may be the same means, but may also be two different means. For example, if the first sealing means is more rigid and mainly ensures improved sealing of the cavity, the second sealing means may be more flexible and mainly provide improved protection of the glass edges.

[0127] In a further aspect, the invention relates to a method for adjusting a length of a central seal between a glass frame and a sliding glass door, the method comprising:

i) fitting a glass frame, at least partly, in a window frame;

ii) laterally coupling the glass frame to the window frame; preferably using an anchoring element; and

iii) adjusting the lateral coupling between the glass frame and the window frame to the desired size of the central seal; preferably by coupling it between the glass frame and the anchoring element.

iv) optionally, fixing the glass frame to the window frame.

[0128] The method has the advantage that the alignment of the glass frame with respect to the window frame can be simpler, more user-friendly and quicker. The anchoring element is connected or is in contact with the window frame which is preferably positioned next to the glass frame. With such a method, the glass frame can slide in the length direction of the sliding glass door, in the length direction of the cavity and/or the length direction of the door sliding system.

[0129] After adjustment, the glass frame can be fixed to the window frame. This may be carried out after installation on site. Fixing ensures that the desired alignment of the glass frame in the sliding glass door will remain in place for longer. Fixing is preferably achieved by means of a fixing means, such as glue.

[0130] In a further aspect, the invention relates to a method for adjusting a height of a sliding system of a sliding door system, the method comprising:

v) movably arranging the sliding glass door on a sliding system provided in a sliding door system;

vi) adjusting the height of the sliding glass door with respect to the sliding door system. In a further aspect, the invention relates to a method for adjusting a height of a sliding system of a sliding door system, the method comprising:

I) fitting a sliding profiled section in an outer frame;

II) fitting a movably arranged sliding glass door (300) in and/or on the sliding profiled section;

III) adjusting the height of the sliding profiled section (410) to the desired height of the sliding glass door.

[0131] The method has the advantage that the adjustment can be simpler, more user-friendly and quicker. In addition, an improvement with regard to the alignment of the sliding means with respect to the outer frame and the sliding glass door may be achieved, as a result of which sliding the sliding glass door can be smoother and simpler.

[0132] In some embodiments, the method comprises the following steps: providing a sliding glass door and placing the sliding glass door in the outer frame for adjusting the height of the sliding profiled section to the desired height of the sliding means.

[0133] In some embodiments, the adjustment is repeated after installation of the sliding door system, preferably at least one month after installation, more preferably a year or two years or longer.

[0134] In a further aspect, the invention relates to the use of a glass spacer according to one or more embodiments as described herein for assembling a glass frame. Preferably, the use relates to assembling a sliding glass door, more preferably a door sliding system. A glass spacer as described herein may produce a glass frame which is more stable and more robust. In addition, the glass spacer may result in a sliding glass door with improved adjustment and alignment. In addition, the glass spacer may result in a door sliding system with improved incident light.

[0135] In a further aspect, the invention relates to the use of a sliding glass door for adjusting a size of a central seal between a glass frame and a window frame. Preferably, the size is the length of the central seal, as discussed above. Such a sliding glass door may lead to an improved alignment for increased incident light.

[0136] In a further aspect, the invention relates to the use of an adjustable sliding system according to one or more embodiments as described herein for adjusting a height of a sliding means or sliding profiled section. Preferably, the sliding means comprises a guide, more preferably a running track and wheels. Such a sliding system may lead to sliding of at least one sliding glass door becoming smoother and simpler. This may, in addition, increase the service life of the sliding system, for example, by readjusting the height of the sliding system after some time.

[0137] In a further aspect, the invention relates to the use of a glass frame, sliding glass door, and/or sliding door system according to one or more embodiments as described herein for closing off a balcony, veranda and/or terrace, for example, in a dwelling.

The anchoring component (150) may have different shapes, but is preferably adapted to the shape of the anchoring element (350). In particular, a free space may be provided in the anchoring component which is suitable for accommodating the anchoring element (350). In the figure, the free space is illustrated as a rectangle in the centre of the anchoring component (150). The walls of the free space may be provided with a profiled section; for example screw thread. In this exemplary embodiment, the anchoring component (150) forms a bridge between the widened component (110) and the elongate component (130). The bridge may be, for example, beam-shaped; as a result thereof, the cross section of the widened component (110) forms a rectangle.

[0141] Fig. 1C shows a diagrammatic representation of a glass spacer (100) according to a third exemplary embodiment. In this exemplary embodiment, the widened component (110) has a wide side and a narrow side. As a result thereof, the cross section of the widened component (110) forms a hexagon, the first segment of the hexagon forming a rectangle and the second segment forming a trapezoid. The two segments are connected to each other, with the long base of the second segment (the trapezoid) forming a side of the first segment (the rectangle). In this case, the second segment (the trapezoid) forms a narrowing which merges into the anchoring component (150).

[0142] Fig. 1D shows a diagrammatic representation of a glass spacer (100) according to a fourth exemplary embodiment. In this exemplary embodiment, the glass spacer (100) furthermore comprises a moisture-absorbing material (115); for example, silica-gel or desiccant granules. In particular, the widened component (110) may comprise a free space in which a moisture-absorbing material (115) may be fitted or incorporated.

[0143] Fig. 1E shows a diagrammatic representation of a glass spacer (100) according to a fifth exemplary embodiment. In this exemplary embodiment, the glass spacer (100) furthermore comprises a gas sealing means (116); for example aluminium foil. In particular, the wide side of the widened component (110) is covered with the gas sealing means (116). Furthermore, the glass spacer (100) in this exemplary embodiment comprises an insertion strip (illustrated by a broken line) for inserting an anchoring element (350) in the anchoring component (150).

[0144] Fig. 1F shows a diagrammatic representation of a glass spacer (100) according to a sixth exemplary embodiment. In this exemplary embodiment, the elongate component (130) comprises two branches at the ends of the elongate component (130). These branches make it possible to fit the elongate component over the corners of a glass pane and/or cover roundings on the side of the glass pane.

Example 2

[0145] Fig. 2A shows a diagrammatic representation of a glass frame (200) according to a first exemplary embodiment. The glass frame (200) comprises multiple glazing; in this exemplary embodiment, the two parallel glass panes (205a, 205b).

[0146] The widened component (110) of the glass spacer (100) is fitted between the two glass panes (205a, 205b). Here, the width of the widened component (110) corresponds to the size of the cavity (240) between the two glass panes. The widened component (110) of the glass spacer (100) is connected to the inner surfaces of the two glass panes (205a, 205b) by a first sealing means (210). This first sealing means (210) may be, for example, Thiokol. The elongate component (130) of the glass spacer (100) is fitted over the sides of the two connected glass panes (205a, 205b). Here, the length of the elongate component (130) corresponds to the thickness of the glass frame (200); in particular the distance between the front and the rear side of the glass frame (200). The sides of the elongate component (130) are connected to a second sealing means (230). This second sealing means (230) may be, for example, Thiokol or silicone.

[0147] Fig. 2B shows a diagrammatic representation of a glass frame (200) according to a second exemplary embodiment. The glass frame (200) comprises an anchoring component (150) which is coupled to an anchoring element (350). The anchoring element may be inserted in a free space provided in the anchoring component (150). In particular, the anchoring element (350) will extend through the elongate component (130). In this case, the anchoring component (150) does not make any contact with the first sealing means (210) and the second sealing means.

[0148] Fig. 2C furthermore shows a diagrammatic representation of the way in which the glass frame (200) according to the second exemplary embodiment (cf. Fig. 2B) can be laterally coupled to a window frame (310) of a sliding glass door (300) in order to form a sliding glass door (300). Here, the anchoring component (150) of the glass spacer (100) is coupled to anchoring element (350) which is anchored to the window frame (310). The free space between, on one side, the side of the glass frame (200) and, on the other side, the side of the window frame (310) forms a central seal (340). By adjusting the coupling between the glass frame (200) and the window frame (310) in the length direction of the glass frame (200), it is possible to adapt the size of the central seal (340) in order to achieve a desired alignment of the glass frame (200) with respect to the window frame (310).

[0149] Fig. 2D furthermore shows a diagrammatic representation of the way in which the glass frame (200) according to the second exemplary embodiment (cf. Fig. 2C) can be laterally fixed to a window frame (310) of a sliding glass door (300) in order to form a sliding glass door (300). Fixing may be brought about by, for example, a fixing means. The anchoring component (350) may optionally be removed after fixing.

[0150] Fig. 3 shows a diagrammatic representation of two glass frames (200a, 200b) coupled to a window frame (310). Each glass frame (200a, 200b) is anchored laterally by means of an anchoring element (350a, 350b) to the window frame (310) in the length direction of the glass frames, in the length direction the cavity and/or in the length direction of the door sliding system (500). In both cases, the anchoring elements (350a, 350b) form a coupling with the anchoring components of the glass spacers (100a, 100b) comprised in the glass frames (200a, 200b); the size of the central seals (340a, 340b) is adjustable by adapting the positions of, on the one hand, the anchoring component of the glass spacer (100a, 100b) and, on the other hand, the anchoring element (350a, 350b). By adjusting these positions, a glass frame (200a, 200b) can slide in the length direction of the sliding glass door (300a, 300b) and/or the length direction of the door sliding system (500) - represented illustratively by a black double arrow. For example, if the anchoring component (350) is a threaded screw, then the length can be adapted by screwing the screw in or out. Consequently, it is thus possible to adapt the size of the central seals (340a, 340b) between the glass frame (200a, 200b) and the window frame (310) to the desired alignment.

[0151] Some prior-art glass spacers (100") are described in order to better illustrate the advantages of the invention. Fig. 4A in particular shows a glass frame (200") in which a conventional glass spacer (100") forms a cavity between two glass panes (205a, 205b). The sides of the glass frame (200") are unprotected and delicate. In addition, the sealing on the side of the glass frame (200") is relatively limited and may easily become damaged. Fig. 4B shows the same glass frame (200") which is fitted in a frame (310") and fixed thereto. The outer frame has to clamp the complete sides of the glass frame (200") in order to offer sufficient protection to the glass frame (200"), as a result of which a large part of the glass panes (205a, 205b) is covered by the frame (310"). Fig. 4C furthermore shows a glass frame (200") in which a joint is provided in the fixing means which is subsequently filled with a structural anchoring (350") which can be coupled to a structure (350") situated behind it; the anchoring will be at right angles to the direction of the cavity. Fig. 4D shows a similar glass frame (200") in which a joint is provided in the glazing (250b). With such glass frames (200"), it is not possible to make adaptations in the direction of the cavity, for example, by continuing to screw, as this may break the gas and water barrier which is formed by the conventional glass spacer. As a result thereof, glass frames which only comprise conventional glass spacers are usually coupled to structures situated behind them. In addition, the size of the central seal can no longer be adapted after installation, for example after the glass frame has been click-fitted in the sliding glass door. As a result thereof, there may be irregularities with regard to the alignment.

Example 3

[0152] Fig. 5 shows a diagrammatic representation of an adjustable sliding system (400) fitted in an outer frame (510) of a sliding door system (500). The adjustable sliding system (400) comprises a sliding means (410) which allows a sliding glass door (300) to slide in the length direction of the outer frame (510). The sliding means (410) may comprise, for example, a guide, such as a rail, which may be coupled to wheels fitted in the sliding glass door (410).

[0153] The adjustable sliding system (400) comprises a sliding profiled section (430) which frames and supports the sliding means (410) and which is coupled to the outer frame (510). The height of the sliding profiled section (430) is adjustable in the direction which is at right angles to the base surface (represented illustratively by a double-headed black arrow); this direction is seen as the height of the sliding profiled section (430).
