Abstract

A glazing support (1) for use in supporting suspended glazing panels comprises a boss (6) having a central through hole (7) through which a bolt is inserted for mounting the glazing support (1) to a structural support (10). Support arms (11) extend from the boss (6). Mounting feet (15, 16, 17, 18) are mounted at the ends of each arm (11). The feet (15, 16, 17, 18) provide supports for bolting attachment to glazing panels (5). Each boss (6, 12, 13, 14) has a vent passageway (50) extending from a base of each socket (30) to the central through hole (7). The boss engaging end (25) of each support arm (11) is coated with an adhesive (51). On insertion of the adhesive-coated spigot end (25) of the arm (11) into the socket (30), air is displaced from the socket (20) and exits through the passageway (50). Each foot (15, 16, 17, 18) has a flattened chamfer (60) to facilitate drilling of a hole (61) in the foot. A vent passageway (70) extends from a base of each socket (35) in a foot through to the centre hole or slot in the foot. The foot engaging end (30) of each support arm (11) is coated with an adhesive (75). On insertion of the adhesive-coated foot engaging end (30) of the support arm (11) into the socket (35), air is displaced from the socket (35) and exists through the passageway (70). This ensures that a tight fit and good adhesive bond is achieved between the spigot end (30) and the socket (35) in the foot. To further enhance the fixing of the foot to the arm (11), a hole is drilled through the foot from the chamber (60) and into the spigot end (30) of the arm (11). A dowel pin (80) is inserted into the drilled hole to further fix the foot to the arm (11). <Figure 4>

Description

“A Glazing Support” Introduction The invention relates to a glazing support of the type comprising a boss for mounting to a structural support, the boss having a number of support arms for mounting to suspended glazing panels. Glazing supports of this type are widely used in providing large uninterrupted glass surfaces.

A problem arises in use of such glazing supports in that a very large number of separate support types must be available to cater for the wide variation in the application of such supports. This is not only expensive but also leads to potential problems if the correct support for a particular structural requirement is not available on site.

Currently available supports comprise either fully casted support or a combination of part machined and part cast supports. These castings, even when of good quality require some fine machining and polishing to bring them to an acceptable standard both technically and aesthetically.

This invention is therefore directed providing a glazing support which will overcome at least some of these problems.

Detailed Description Referring to the drawings there is illustrated a glazing support 1 for use in supporting suspended glazing panels. The support 1 comprises a boss 6 having a central through hole 7 through which a bolt is inserted for mounting the glazing support 1 to a structural support 10. In this case four identical support arms 11 extend from the boss 6. Respective mounting feet 15, 16, 17, 18 are mounted at the ends of each arm 11. The feet 15, 16,17,18 provide supports for bolting attachment to the glazing panels 5.

Referring in particular to Figs. 4 to 11 the glazing support 1 may comprise one of four different bosses, each of which is of generally frustroconical shape. The boss 6 of Fig. 11(d) has four sockets 20 which are equi-spaced circumferentially around the conical portion of the boss 6. A second boss 12 (Fig. 11a) has a single socket 20, a third boss 13 (Fig. lib) has two sockets 20, and a fourth boss 14 (Fig. 11c) has three sockets 20. The selection of boss will depend on the number and configuration of support arms 11 required. It will be appreciated that a single boss may be provided with four sockets 20, some of which may be blanked off with inserts, if required.

Each support arm 11 has a spigot 25 at one end for engagement in a boss socket 20 of a boss such as the boss 6. A spigot 30 at an opposite end of the support arm 11 is engagable in a corresponding foot socket 35 of a mounting foot 15,16,17,18.

There are four different mounting feet 15, 16, 17, 18 one 15 with a relatively small hole, another 16 with a larger hole and two 17, 18 (one right, one left) with an elongate slot. The arrangement of Figs. 1 and 2 is typical to facilitate attachment to four adjacent glazing panes.

A kit comprising a single boss type, a single arm type and a number of different mounting discs may be used to assemble either on site or off site, appropriate glazing supports for a given structure. This is achieved by mounting the support arms 11 to the boss 6 and mounting the appropriate mounting feet discs 15,16,17, 18 to the ends 30 of the support arms 11.

Each boss 6, 12, 13, 14 has a vent passageway 50 extending from a base of each socket 20 to the central through hole 7. The boss engaging end 25 of each support arm 11 is coated with an appropriate adhesive such as code 638 available from Loctite. The adhesive coating is indicated by a thick black line 51 in Fig. 4. On insertion of the adhesive-coated spigot end 25 of the arm 11 into the socket 30, air is displaced from the boss socket 20 and exits through the passageway 50. This is important in ensuring that a tight fit and good adhesive bond is achieved between the spigot end 25 and the socket 20 in the boss. ΙΕΟ 5 008 2 - 8 Each foot 15, 16, 17, 18 has a flattened chamfer 60 to facilitate drilling of a hole 61 in the foot as illustrated particularly in Figs. 6 and 7. A vent passageway 70 extends from a base of each foot socket 35 through to the centre hole or slot in the foot. The foot engaging end 30 of each support arm 11 is coated with an appropriate adhesive such as code 638 available from Loctite. The adhesive coating is indicated by a thick black line 75 in Fig. 4. On insertion of the adhesive-coated foot engaging end 30 of the support arm 11 into the foot socket 35, air is displaced from the socket 35 and exits through the passageway 70. This ensures that a tight fit and good adhesive bond is achieved between the spigot end 30 and the socket 35 in the foot. To further enhance the fixing of the foot to the arm 11, a hole is drilled through the foot from the chamfer 60 and into the spigot end 30 of the arm 11. A dowel pin 80 is then inserted into the drilled hole to further fix the foot to the arm 11. This improves the load bearing/transmission characterisations of the system Referring to Figs. 12 to 18 there is illustrated another support comprising an assembly of a centre boss, support arms and feet. The parts and the method of assembly are similar to those described above and like parts are assigned the same reference numerals. This support is typically used when a straight connection is required.

Referring to Figs. 19 to 28 there is illustrated another support comprising an assembly of a centre boss, support arms, and feet. The parts and the method of assembly are again similar to those described above and like parts are assigned the same reference numerals. In this case, the arms are short and there is an additional support element 90 to which the centre boss is attached by fixing screws 91.

In the preferred embodiment described above the support arm has a boss engaging spigot at one end and a foot engaging spigot at the other end. This is advantageous both in terms of load transmission and ease of manufacture. It is relatively easy to coat the spigots with adhesive as described above for adhesive bonding with the boss socket and foot socket respectively. It may however be possible but not as ΙΕΟ 3 008 ί - 9 advantageous to provide a spigot on one or both of the foot or boss for engagement wit ha socket(s) in the support arm.

This invention provides a relatively simple kit that may be used to assemble a very large number of different glazing supports. Assembly is optimised as the supports can be very quickly assembled and fixed together to provide load bearing and transmission characterisations.

All the individual parts of the support assembly of the invention may be manufactured by machining processes and therefore they are capable of achieving acceptable standard both technically and aesthetically directly from the machine without any further enhancement by polishing or otherwise.

Other advantages include a more economical stocking arrangement because bosses, arms and mounting feet or discs can be procured in economical quantities and taken from stock and assembled as required.

Lead-in times for procurement are much improved as the raw material (solid stainless steel tube) is a standard off the shelf item. In contrast, castings must be produced in large quantities to be economical due to set up charges involved. With the present invention, even small quantities can be procured quickly and at economic cost.

The invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail.
