THE FIELD OF THE ART
[0001] The invention relates to an angular joint employed in the process of angular connections
of hollow profiles, such as in the orthogonal connections of profiles being previously
cut at 45° and coming to contact to form parallelepipedal frames for doors or windows.
[0002] Joints for door and window profile frames of the prior art of the type of spring
activated button means removably engaging into suitable apertures of the profiles
to stabilize the angular connection thereof, require, prior to employment thereof,
the opening of apertures at precisely selected locations of the profiles wherein are
removably engaged the abovementioned spring activated buttons. This process is awkward
and time consuming due to the accuracy required in marking and drilling of the apertures
and often leads to an imperfect fit of the profiles and to a structure of reduced
aesthetics and functionality due to the non-alignment of the profiles.
[0003] EP 0 644 312 discloses a set-square connecting structure for right angle connections of profile
frames for frames for doors and windows, wherein a pair of apertures is required in
the profiles being brought for connection, for engagement of protruding teeth of the
connecting structure into these apertures and the safe locking of the profile sections
with one another.
EP 0235 039 and
FR 2 429 350 also disclose connecting devices for the assembly of tubular profiles for the formation
of door/window frames, which function through the engagement of protruding buttons
into correspondingly sized side apertures in the profiles being brought together for
connection.
[0004] Similarly
WO 02/075093 and
US- 6,042,298 also require the accurate opening of side apertures onto the profiles to be connected,
and they further include a plurality of components that make the joint rather complex
and of increased manufacturing and assembly cost.
[0005] GB-2 072 296 discloses a joint wherein a clamping member is moved through a bolt being screwed
along the line of matching contact of the profiles so that opposed hooks of the clamping
member are drawn into engagement with punched depressions in the outside walls of
the hollow sections being connected. Application of such a joint in practice requires
employment of the specific type of profile being proposed in this patent, whilst the
requirement of punched depressions at precisely measured locations, worse than the
opening of side apertures onto the profiles to be connected wherein the nature of
openings might allow marginal fitting tolerances, poses a further problem that the
dimensions of the profiles having being cut and punched or perforated industrially
cannot be altered on site, as their installation might require, because the punches/perforations
would move out of place and would therefore render the joint inapplicable.
[0006] US - 5, 109,645 discloses a symmetrical shaped metal angle piece with resilient end portions and
sharp edged terminations, that slides freely on being entered within the hollow profile
sections being connected, but thereafter locks into engaged, non withdrawable relation,
due to the reversed attitude of the resilient end portions and their associated sharp
edges. Although this joint is mainly directed to serve a permanent connection of the
profiles, if disconnection of the frame is desired, one has to attempt, through slots
in the profile walls, to pry inwardly the profiles and release them from jamming engagement.
Although simple, the joint in US-5, 109,645 is unable of obtaining perimetrically
precise contact of the profiles being connected, thereby leading to technical and
aesthetic drawbacks, whilst its structure does not render it capable of withstanding
heavy loads in the range of tons, normally required with door/window frames, without
creating undesirable gaps along the plane of matching contact of the hollow profile
sections.
[0007] The object of the present invention is to provide for an angular joint of hollow
metallic profile members being brought together for the formation of door or window
frames and the like, said angular joint being simple in construction, easily assembled
or disassembled and providing a self-aligned, rigid connection of the profile members.
[0008] A further object of the invention is the elimination of the need for accurately marking
and subsequently opening of side apertures onto the profile members being connected,
thereby substantially facilitating and speeding up of the assembly process.
[0009] Another object of the invention is to provide for alternative embodiments of the
joint of the invention, adapting it to various applications extending beyond the field
of orthogonal connections of hollow profile members being connected to form door and
window frames and making the joint of the invention applicable in connections of profile
members of any kind and at any angle whatsoever.
[0010] The angular joint of the invention comprises a slide base portion 1 and a sheet metal
mobile portion 2 superimposed thereupon, the sheet metal portion 2 including upwardly
extending legs 2e with indenting edges 2g, a bolt 3 being employed in the tightening
process of the joint, wherein after the joint has been inserted into the hollow profile
members being brought together for connection, the bolt 3 acts so as to exert an upwardly
raising force onto the sheet metal mobile portion 2, whilst maintaining base portion
1 at a fixed position, and subsequently leading the sharp indenting edges 2g of the
sheet metal portion 1 to producing an indentation effect into the walls of the corresponding
chambers 13a, 13b of the hollow profiles being angularly connected with the joint,
as the joint is being tightened, thereby resulting in a robust, self aligned connection
of the hollow profile members.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0012] The joint of the invention is particularly related with the assembly of frames that
are being assembled from previously cut lengths of profiles e.g. aluminium or plastic
profiles, such profiles having a hollow section to allow introduction and operation
of the joint. A broad, but not exclusive, field of application of the invention is
the connection of profile members in the corners thereof, when they are brought together
to form generally parallelepipedal frames or casings for door and window applications.
Such profile members are previously cut at 45° at the matching edges thereof to allow
for an optimally aesthetic fit of the orthogonal connection.
[0013] Thus, whilst the joint of the invention has a necessarily orthogonal configuration
in the particular application, it may equally well have the configuration of an acute
or an oblique angle to serve applications wherein the hollow profile members are connected
at an acute or an oblique angle respectively.
[0014] The dimensions of the joint of the invention may naturally vary to make it compatible
with different sizes and sections of profile members.
[0015] An illustrative hollow profile member 50 is shown in Fig. 1a, such profile member
50 comprising a pair of parallel walls 50c, 50d extending on the one hand at an open
end 50a wherein is fitted the item that is being framed by such perimetrically covering
length of the profile member, e.g. a glass or shutter panel for a door or window assembly,
and on the other hand at and end 50b, opposite to the open end 50a, end 50b being
fixedly mounted to the casing. A chamber 13a,b is formed in between 50a and 50b, such
chamber serving for the introduction of the joint of the invention. Whilst other details
of the profile members to be connected may vary, the chambers 13a,b are available
for the employment of the joint of the invention. The drawings therefore depict the
abstract detail of such rectangular chambers 13a and 13b with respective open ends
12a, 12b of the hollow profile members being brought together for connection.
[0016] The joint of the invention shown in Fig.1 comprises a fixed slide base portion 1
and an elastically deformable sheet metal portion 2 superimposed onto the fixed slide
base portion 1 and having a configuration that generally corresponds to the surface
of the base portion 1 whereupon it is being seated. Both portions 1 and 2 are symmetrically
arranged on either side of plane x-x' (Fig. 2b), a central bolt 3 with a screwing
head end 3a and a sharp edge 3b also passing through the same plane of symmetry x-x'
being driven by means of a screw driver 14, wherein this plane of symmetry x-x' coincides
with the plane of contact of the two hollow profile members being brought together
for connection.
[0017] The fixed slide base portion 1 is an angular item with a pair of planar outer sides
1e forming an angle corresponding to the angle at which the profile members are being
connected, at this instance an angle of 90°, a slight planar recession 1g being formed
near the junction of these outer sides 1e, such planar recession 1g serving as a means
of overcoming possible obstacles in the course of sliding of these outer sides 1e
onto the walls of corresponding chambers 13a, 13b, that might be due to possible imperfections
in the cutting and finishing process of the edges of the metal profile members being
brought together for connection. The slide base portion 1 forms a flat basement portion
1a overlying the junction of the above outer sides 1e with a cavity 1b being centrally
located thereupon to serve the purpose of receiving the sharp edge 3 b of bolt 3.
[0018] On either side of the above flat basement portion 1a, that is perpendicularly oriented
with regard to the plane of symmetry x-x' the inner sides of the fixed slide base
portion 1 extend to a pair of planar sections 1c which are substantially parallel
to the walls of profile chambers 13a,b whereupon the outer planar sides 1e are seated
and subsequently extend into convergent portions 1d terminating at symmetrically located
edges 1f. The herein above described configuration of the sides of the fixed slide
base portion 1 substantially improves the characteristics of the process of sliding
of the sheet metal mobile portion 2 onto the fixed slide base portion 1 as will be
explained hereinafter.
[0019] The sheet metal mobile portion 2 has a configuration generally identical with the
configuration of the slide base portion 1, with an upper basement 2a with a centrally
located cavity 2b wherein is being driven the sharp edge 3b of the tightening bolt
3, wherein the upper basement 2a lies perpendicularly to the plane of symmetry x-x'
and symmetrically above the basement 1a of the base portion 1. In turn, the upper
basement 2a symmetrically extends to planar side surfaces 2c and 2d, each with a length
generally equivalent to the length of underlying surfaces 1c, 1d of the base portion
1, whereupon they slide.
[0020] The sheet metal mobile portion 2 is bent upwardly at the terminals 2f of side surfaces
2c-d at an angle (180-θ)° as illustrated in Fig. 2c, and extends to upwardly extending
sides 2e on either side thereof terminating at sharp edges 2g, such upwardly extending
sides 2e thereby being oriented in a direction substantially parallel to the plane
of symmetry x-x'.
[0021] In accordance to a first preferred embodiment of the invention the abovementioned
centrally located cavity 2b in the sheet metal mobile portion 2 is drilled through
to form an opening with internal threading for the passage of bolt 3. In Figs. 7a-c
are depicted possible alternative solutions for implementing such hole with internal
threading. In Fig. 7a hole 2b is being formed by expansion of the sheet metal into
a cylindrical collar 19 that is subsequently internally threaded. In Fig. 7b is depicted
an alternative solution of employment of an additional plate 18 having a planar surface
18a with dimensions such as to fit onto the basement 2a of the sheet metal portion
2 and a central hole 18b that is internally threaded and coincides with hole 2b on
the basement 2a when plate 18 is brought in contact with basement 2a. Finally in Fig.
7c is depicted an additional internally threaded cylindrical collar 48 with a body
portion 48a and a central hole 48b coinciding with hole 2b of the sheet metal portion
2.
[0022] In the case wherein cavity 2b in the sheet metal portion 2, is drilled through and
forms a thorough internally threaded hole, such hole being implemented in either one
of the illustrative embodiments of Figs 7a-c, bolt 3 is driven through this hole 2b
and terminates by contact of the sharp edge 3b thereof onto the cavity 1b being provided
axially underneath hole 2b on the fixed slide base portion 1. Whilst this condition
corresponds to the joint having been assembled but not tightened as shown in Fig.
2a, when as shown in Fig. 2b, by means of screw driver 14 the bolt 3 is being screwed,
the force being exerted by the firm contact of the sharp edge 3b thereof onto the
cavity 1b of the slide base portion 1 maintains the latter firmly in contact with
the walls of the profiles being connected, whilst it produces a reactive force that
pushes upwardly the sheet metal mobile portion 1 until the sharp edges 2g thereof
indent the relatively softer walls of the profile members being connected, thereby
achieving a robust, self aligned connection thereof, such self alignment being obtained
as a result of the above mentioned indenting of the walls of the profile members extending
along a substantial length of the sharp edges 2g of the sheet metal mobile portion
1.
[0023] Fig. 2c characteristically depicts a magnified view of a detail in the process of
tightening of the joint of the invention. Herein is shown that following indenting
of the sharp edges 2g of the sheet metal portion 1 into the walls of corresponding
chambers 13a, 13b of the profiles to be connected, further screwing of bolt 3 results
in a perfect convergence of the profiles to be connected along the axis of symmetry
x-x', whilst the upwardly extending sides 2e of the sheet metal portion 2 move through
an infinitesimal distance a', having a length of the order of a fraction of a mm,
thereby being deflected at an angle θ'° relatively to the side surfaces 2d of the
sheet metal mobile portion 2. Resilient stresses are thereby stored in sheet metal
portion 2, uniformly applied on either side of the joint, such stresses thereby maintaining
the joint in a tightened condition and the profile members rigidly connected even
if an accidental slight release of bolt 3 may occur.
[0024] In accordance to an alternative embodiment of the invention, instead of opening a
hole through the above cavity 2b in the sheet metal mobile portion 2, a hole is drilled
through the corresponding coaxial cavity 1b of the fixed slide base portion 1 as shown
in Fig. 3. The bolt 3 is then being driven from the inner junction of the profiles
to be connected and sharp edge 3b thereof firmly contracts sheet metal portion 2 at
cavity 2b thereof and exerts a raising force thereupon, eventually resulting in the
indentation of the walls of the profiles to be connected by the sharp edges 2g of
the upwardly extending sides 2e of the sheet metal mobile portion 2.
[0025] The form of the sharp edges 2g of the upwardly extending sides 2e of the sheet metal
mobile portion 2 is selected so as to render an optimum indentation effect. Thus,
they may for example have the toothed form depicted in Fig. 1 or Fig. 4a and Fig.
4b or they may take the double razor edge like form of edges 20g in the upwardly extending
sides 20e of an alternative embodiment of the invention depicted in Figs 5, 5a, wherein
the mobile portion 2 of the joint of the invention is made from a profile of hard
aluminium alloy with an upper basement 20a provided with a centrally located hole
20b and sides 20c - 20d in sliding contract with corresponding sides of the underlying
slide base portion 1. A single razor edge ending of upwardly extending sides 20e of
the mobile portion 20 made from hard aluminium alloy may be equally effective in the
indentation of the relatively softer walls of the hollow profiles to be connected,
however the double razor edge like configuration further serves the purpose of a secure
sequential indentation of the walls of the profile members.
[0026] Alternatively, as shown in Fig. 5b, the upwardly extending legs 20e of the mobile
portion 20 may form a recession, wherein an independent sheet metal plate 15, preferably
with toothed edge configuration may be fitted to serve as an indentation means.
[0027] A further alternative embodiment is shown in Fig. 5b, wherein legs 20e may extend
to a plurality of pointed pins 20g'.
[0028] Finally in Figs 6a, 6b the sheet metal portion 2 is alternatively made with side
surfaces 2c ending at a bent structure of the sheet metal portion forming a recession
17 for the engagement of a wire 16, made from steel in the form of a II section in
substitution of the otherwise planar sides 2d of the sheet metal portion 2, with the
legs thereof bent to upwardly extending members with sharp edges 16g playing the role
of profile wall indentation elements. In this embodiment, the fixed base portion 1
may be made in two identical portions, symmetrically on either side of the plane of
symmetry x-x', the two identical portions being pivotally connected around a pivotal
axis 60 and thereby being appropriate for the connection of hollow profiles forming
varying angles at the junction thereof. The sheet metal mobile portion 2 might under
such circumstances also be adjustable to profile connections at varying angles with
the pivotally mounted end portion 16 thereof.
[0029] The fixed slide base portion 1 of the joint of the invention may also receive alternative
forms. In Fig. 4a base portion 1 is provided with elevated end walls 6 with opposing
central nerves 5 that fit into recessions 4 of the sheet metal mobile portion 2. Alternatively
in Fig. 4c, base portion 1 does not terminate in the abovementioned terminals 1f,
but is bent upwardly following a configuration similar to that of the sheet metal
portion 2, so that the upwardly extending legs 2e of the latter may fit into the recessions
being formed by the upwardly extending legs 1e' of the fixed slide base portion 1.
[0030] The joint configuration depicted in Fig. 4a and preferably that of Fig. 4c serves
as an advantageous embodiment, wherein the sheet metal mobile portion 2 fits tightly
into slide base portion 1, so as to facilitate packaging of the joint and enable handling
of the same as if it were a single item.
[0031] Fig. 4b shows an alternative embodiment of the base portion 1 of the invention, which
is more bulky and is applicable in cases of rather wide profile connections, wherein
due to the bulk of the base portion 1, it is preferably made with perforations 7,
in order to reduce material cost and weight of the item.
[0032] Fig. 8a depicts an alternative embodiment of the joint of the invention, wherein
the sheet metal portion 2 is made in two discrete, independent parts, whilst the single
item of the base portion 1 further comprises flat plate extensions 1h perpendicularly
located on either side near the top thereof, wherein these flat plate extensions 1h
have an internally threaded hole, whilst the upper basement portion of sheet metal
mobile portion 2 is substituted by a perpendicularly bent portion 2h also perforated
coaxially with the internally threaded hole of the flat plate extension 1h of the
slide base portion 1, so that a bolt 3c passing through these coaxial holes with its
head blocked by flat plate extension 1h and with a nut at the other end thereof at
the bottom of the flat plate extension 2h of the mobile portion 1 serves as the means
of unilaterally tightening the joint.
[0033] Whilst in other embodiments a centrally located hole being opened in two halves 11a
and 11b at the upper corner (or lower corner in case of the embodiment of Fig. 3)
junction of the profiles to be connected is sufficient for tightening the joint of
he invention, in the case of the embodiment of Fig. 8a two distinct holes 11a, 11b
are necessary in the corresponding chambers 13a, 13b of the profile members being
connected.
[0034] Employment of the joint of the invention advantageously leads to a novel method of
angular connection of hollow profile members made from aluminium, plastics or other
materials that offers enhanced speed and is user friendly, this method comprising
the following steps:
- a. Drilling of a single hole made of two halves 11a, 11b, one half in each of the
hollow profile members being brought together for an angular connection, the edges
of such profile members having previously being appropriately cut at an angle of half
the magnitude of the angle intended by their connection, e.g. being cut at an angle
of 45° when the angle intended by their connection is 90°.
- b. Inserting the previously assembled joint with a central bolt 3 passing through
the upper sheet metal mobile portion 2 and stopping at the underlying base portion
1, through the opening 12a of a chamber 13a of a first one of the pair of hollow profile
members to be connected, wherein half of the joint is introduced in this first one
of the pair of profile members.
- c. Bringing the chamber 13b of the second one of the pair of hollow profile members
to be connected in a position wherein the protruding half of the joint is slidably
inserted therein, thereby obtaining an accurate coincidence of the previously cut
edges of the hollow profile members to be connected and further obtaining the centrally
located angular hole 11a, b by coincidence of the two halves 11a, 11b.
- d. Employment of a key 14 passing through the angular hole 11a, b and rotation by
means of the same of the bolt 3 lying coaxially along the plane of connection of the
two hollow profile members that have been connected, until the sharp edges of the
upwardly extending sides of the sheet metal portion 2 indent the walls of chambers
13a, 13b thereby leading to a rigid, aligned and angular connection of the abovementioned
hollow profile members.
