Description

I
Coupling Element and Method of Connecting Articles This invention relates to coupling elements and methods for connecting articles with particular, but by no means exclusive, reference to applications in glazing in which frame members are coupled so as to retain a glass panel or like therebetween. Also, the invention relates to frame members for glazing.
It is commonly desired to provide doors having glazing apertures in which a glass panel or like is disposed. It is well known to provide a glazing cassette in which the glass panel is retained. The glazing cassette is then installed in a door using well-known techniques. Typically, the glazing cassette comprises two frame members, one of which is provided with a plurality of plugs, and the other of which is provided with a plurality of corresponding apertures. The frame members are coupled together so as to retain a glass panel disposed therebetween. This is done by positioning the plugs in the corresponding apertures, and fixing them in place using screws which are screwed into the plugs. Afterwards, a cap is positioned over the screw-heads. This procedure is time consuming and somewhat difficult to perform. Additionally, the end result is not aesthetically pleasing.
The present invention, in at least some of its embodiments, addresses the above described problems. The skilled reader will appreciate that, whilst the present invention is particularly directed towards glazing cassettes such as glazing cassettes of the type installed in doors, the invention has further application in the coupling of articles per Se.
According to a first aspect of the invention there is provided a coupling element including an elongate member having a first end and a second end, a first plurality of barbs disposed successively along the elongate member. from the first end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the first end, and a second plurality of barbs disposed successively along the elongate member from the second end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the second end.
Generally, the barbs in the first plurality of barbs depend inwardly from the first end, and the barbs in the second plurality of barbs depend inwardly from the second end.
Preferably, the elongate member is linear.
In preferred embodiments the elongate member is cylindrical, although other shapes, such as an elongate member having a square cross section or a cross section corresponding to another polygon, are possible. Generally, the elongate member is of constant cross-sectional shape dimension along its length, although it is possible to provide elongate members that taper or have sections of differing cross sectional dimension and/or shape.
In a preferred embodiment, the barbs are in the form of collars which are circumferentially disposed around the elongate member. Typically, the collar include a sloping portion sloping away from the first end (in the case of a barb in the first plurality of barbs) or the second end (in the case of a barb in the second plurality of barbs) and a back wall extending substantially perpendicularly from the elongate member.
The first plurality of barbs and the second plurality of barbs may each consist of at least three, preferably three to ten, most preferably three to six barbs.
Preferably, the coupling element consists essentially of the elongate member, the first plurality of barbs and the second plurality of barbs.
According to a second aspect of the invention there is provided a method of connecting two articles including the steps of: providing a plurality of coupling elements, each including an elongate member having a first end and a second end, a first plurality of barbs disposed successively along the elongate member from the first end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the first end, and a second plurality of barbs disposed successively along the elongate member from the second end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the second end; bringing a first article into engagement with the coupling element from the first end thereof; and bringing a second article into engagement with the coupling element from the second end thereof.
The first and second articles may be brought into mutual contact.
Preferably, the first article and/or the second article has a bore formed therein into which the coupling element is positioned.
According to a third aspect of the invention there is provided a method of glazing including the steps of: providing a coupling element including an elongate member having a first end and a second end, a first plurality of barbs disposed successively along the elongate member from the first end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the first end, and a second plurality of barbs disposed successively along the elongate member from the second end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the second end; bringing a first frame. member into engagement with the coupling elements from the first end thereof; positioning a glass panel or like in the first frame member; and bringing a second frame member into engagement with the coupling elements from the second end thereof so that the glass panel is retained between the first and second frame members.
It will be appreciated that it is possible to perform some of the steps in a different order; for example, it is possible to position the glass panel in the first frame member before bringing same into engagement with the coupling elements.
In a preferred embodiment the first frame member and/or the second frame member have bores formed therein into which the coupling elements are positioned. Advantageously, the first and/or second frame members have a plurality of projections disposed thereon, each projection having a bore into which a coupling element is positioned. Most preferably, the first and second frame members each have a plurality of projections disposed thereon, each projection having a bore into which a coupling element is positioned, and the step of bringing the second frame member to engagement with the coupling elements causes projections of the first frame member to abut corresponding projections on the second frame member.
Preferably, the method further includes the step of installing the first and second frame members and glass panel retained therebetween in a door.
Advantageously, the door is of the type which utilise a pair of plastic door skins.
Examples of such doors are described in GB 2267529 in which the door skins are mounted on a frame, and panels of a suitable material are located within the frame between the door skins.
The first and second frame members and glass panel retained therebetween may be installed in a suitable cavity provided in the door.
Alternatively, at least one of the first and second frame members may be in the form of a door skin. The first and second frame members may be formed from a resilient plastics material, preferably polystyrene.
According to a fourth aspect of the invention there is provided the use in glazing of a coupling element including an elongate member having a first and a second end, a first plurality of barbs disposed successively along the elongate member from the first end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the first end, and a second plurality of barbs disposed successively along the elongate member from the second end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the second end.
According to a fifth aspect of the invention there is provided a kit of parts for use in glazing including: a first frame member and a second frame member for retaining a glass panel or like therebetween; and a plurality of coupling elements, each coupling element including an elongate member having a first end and a second end, a first plurality of barbs disposed successively along the elongate member from the first end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with thecoupling member from the first end, and a second plurality of barbs disposed successively along the elongate member from the second end and shaped so as to hinder or prevent the removal of an article which has been brought into engagement with the coupling member from the second end.
According to a sixth aspect of the invention there is provided a glazing frame including a first frame member and a second frame member for retaining a glass panel or like therebetween, in which the first and second frame members each have a plurality of projections disposed thereon,, each projection having a bore, and the projections on the first and second frame members are in register so that, in use, the projections on the first frame member abut corresponding projections on the second frame member, thereby allowing a glass panel or like to be retained between the first and second frame members.
Embodiments of coupling elements, glazing frames and methods for coupling articles will now be described with reference to the accompanying drawings, in which:-Figure 1 shows a coupling element of the invention; Figure 2 shows an exploded view of a glazing frame having first and second frame members and a glass panel for retention therebetween; and Figure 3 shows the coupling of the first and second frame members.
Figure 1 depicts a coupling element, shown generally at 10, of the invention having a cylindrical elongate body 12, a first set 14 of barbs 16, and a second set 18 of barbs 16. Conveniently, each barb 16 is in the form of a collar which is circumferentially disposed around the elongate body 12, although other forms of barbs would readily occur to the person skilled in the art. The collars include a sloping portion that might slope at a suitable angle, for example between 5 and 450, more preferably between 5 and 20 , most preferably between 7 and 15 , from the elongate body, although it is also possible to provide sloping portions that are shaped so as to provide a variable angle of slope. The collars also include a back wall that extends substantially perpendicularly from the elongate body 12. The barbs 16' in the first set 14 of the barbs are disposed successively along one half of the elongate body 12, the first barb in the set being near to a first end 12a and the final barb in the set being near to the middle of the elongate body 12. The barbs in the first set 14 depend inwardly from the first ends 12a. The barbs 16 in the second set 18 of the barbs are disposed successively along the other half of the elongate body 12, the first barb in the set being near to a second end 12b and the final barb in the set being near to the middle of the elongate body 12. The barbs in the second set 14 depend inwardly from the second end 12b. The coupling element is conveniently formed from a metal, although other materials, such as suitable plastics materials, might be utilised.
In a preferred embodiment of the invention, the coupling elements are used to couple a pair of frame members together for glazing purposes. Figure 2 shows an exploded view of a glass or like panel 20 sandwiched between a first frame member 22 and a second frame member 24. A plurality of coupling elements 26, which can be of the type depicted in Figure 1, are used to couple the first and second frame members 22, 24 together. Each frame member 22, 24 has a recessed section 28 which is shaped to accommodate snugly the glass panel 20, and a plurality of projections 30. Each projection 30 has a bore formed therein of a diameter suitable to accept and engage with a coupling element 26. The projections 30 on the first frame member 22 and second frame member 24 are positioned in register. Further projections 32 may be provided on the first and second frame members 22, 24. Each further projection has a corresponding further projection disposed on the other frame in register therewith, and pairs of further projections 32 that are in register have co-operating male and female portions which are mutually engageable so as to assist in the positioning of the first and second frame members 22, 24.
In use, coupling elements 26 are introduced into the bores in the projections 30 so as to engage with the inner walls of the projections 30. Figure 3 shows a coupling element 26 positioned in a projection 30 in this manner. The glass panel 20 is then positioned in the recess section 28 of a frame member which is defined by a raised wall section 29. Thereafter, the projections 30 of the other frame member are aligned with the coupling elements extending from the projections 30 of the first frame member. The projections 30 of the second frame member are then brought into engagement with the protruding barbs of the coupling elements, and sufficient pressure is applied so that the projections of the first frame member 22 abut the projections of the second frame member 24, thereby retaining the glass panel 20 between the first and second frame members 22, 24. The procedure is straightforward and convenient, and the nature of the coupling elements provide for a certain amount of "slack" in their positioning in the projections.
The invention provides very strong coupling between the frame members, and it is believed that this is, in part, due to the material of the frame members slightly swelling behind the barbs, thereby preventing removal of the coupling elements from the frame members. A further advantage is that the coupling elements are not visible in the finished glazing unit, thereby providing an aesthetically pleasing finished appearance. The frame members and glass panel retained therebetween can be used for a variety of glazing purposes, such as installation in a door. However, many other articles might be coupled using the principles of the present invention.
