Description

1 2451468 A RetaininE Device for a Glazed Unit
Field
This invention relates to retaining devices for retaining glazed units within their surrounding frames and is particularly suitable for use with windows having external beading.
Background of the Invention
Windows having glazed units may be internally glazed or externally glazed, i. e. the glazed panel is held in place within a window frame by beads secured to the internal surface or external surface of the window frame. Window frames having external beads may pose a security risk in that the beads can be prised away by unauthorised persons outside of a building to enable the glazed panel to be removed.
Retaining devices such as that disclosed in GB-A-2344 372, have been proposed to improve security of externally glazed units. The fitment of such security devices may cause problems if the glazing units need to removed from their respective frames for maintenance or replacement for some reason.
Glazed units are typically centred within their frames by the use of packing members which typically may comprise wedges which are inserted into the gaps between the frame and unit to hold the glazed unit substantially in alignment with the frame. These packing members may be formed as corner packing members as is described in EP-A-0526022.
The present invention seeks to provide a retaining device which is fitted in combination with a packing member

The glazing units 14 are typically centred within the frame 10 by the use of packing members 21 or 21A.
The packing member may form part of a corner packing assembly 21 as shown in Fig. 6 or may be a simple wedge shaped packing member as is shown in Fig. 7.
A retaining device 31 is secured to the frame 10 for holding the glazed unit 14 within the externally glazed frame in the event that the external beading 15 is removed. With reference also to Figs. 2 -5, the retaining device 31 comprising a first bracket 32, which in use is secured to said frame 10, a second bracket 33 which is mounted on the first bracket, and a wedge member 34 which in use is inserted between the second bracket 34 and the glazing unit 14.
The first bracket 32 comprises a substantially rectangular base 35 having an underside 36 facing the frame with a detent 37 formed integrally with one end portion of the base 35. The base 35 has holes 39 formed in the other end portion to facilitate fasteners (not shown) for securing the first bracket to the frame 10. The detent 37 is a longitudinally extending lug joined to the base 35 along one side and is offset above the base to extend inwardly of the glazing unit 3. The base 35 may be secured directly to a frame 10.
Alternatively, the base 35 may be provided with a peripheral downwardly extending flange 38 forming a hollow to accommodate a packer 21. Preferably the hollow base 35 is wedge shaped in longitudinal section so to accommodate in use a wedge shaped packer 21 or 21A on which the first bracket 32 is mounted.
The second bracket 33 also comprises a substantially rectangular base 41 which is similar is dimensions to the base 35 of the first bracket 32. The base 41 has an underside 42 facing the first bracket 32 and has a flange 43 extending upwardly on the outer side thereof The flange 43 holding the glazed unit 14 in place. An abutment means 44, in the form of a longitudinalJy extending lug 44 is formed at one end portion of the base 4] on the underside thereof for engagement with the detent 37. The lug 44 is formed integrally with the base 41 being joined on one side to said end portion of the base 41 and offset below the base. The lug 44 extends outwardly of the glazing unit 14 such that the lug 44 on the second bracket 33 in use passes underneath the lug 37 on the first bracket 32, when the two brackets are inter-engaged. The two lugs 37, 44 in use co-operate to limit outward movement of the glazing unit. 7. The lug 44 on the second bracket is provided at each end with upwardly directed tabs 45 so that the two lugs 37,44 are mutually inter-engagable only when correctly aligned with each other.
The base 41 is provided with an upstanding tang 46 formed out of said one end portion of the base 41 adjacent the flange 43, with two raised catches 47 formed in the other end portion of the base 41 also adjacent the flange 43. The catches 47 and tang 46 are in longitudinal alignment relative to the base.
The wedge member 34 is substantially rectangular having similar dimensions to the base 4] of the second bracket 34 and has flange 51 extending upwardly on the outer side thereof The flange 51 in use locates between the glazing unit 14 and the flange 43 on the second bracket. The wedge member 34 has a longitudinally elongate slot 52 formed in one end portion thereof adjacent the flange 5] and which is use accommodates the tang 46 allowing the wedge member to slide longitudinally of the second bracket 33. The underside 53 of the wedge member 34 is provided with an longitudinally elongated recess 54, or through slot ( not shown) to accommodate the upturned tabs 45 on the lug 44.
