Abstract

A flexible spacing plate for use between an opening and a window frame has a U-shaped construction which is adapted to surround a fastening screw or the like and a portion which is resilient and is formed by at least one resilient hinge. On application of force to the non-planar resilient portion of the spacing plate during installation the plate becomes substantially flat. <IMAGE>

Description

SPACING PLATES The present invention relates to spacing plates and, in particular, to spacing plates which are open at one end.
Spacing plates are used, for example in window buildings, to fill the space between the window frame and the wall to which the window frame is attached.
Spacing plates of a substantially U-shaped configuration are known in the art and are placed over a fastening screw which is used to secure the window frame to the wall. However, these U-shaped spacing plates are difficult to retain in position during the screwing of the fastening screw into the wall. It is therefore difficult for a person working alone to ensure that the spacing plate stays in position whilst screwing the fastening screws into the wall.
EP-A-Ol2702l discloses a lamellar plate-like spacing plate with a slot which is open at one end, the spacing plate consisting of plastics material and having at least one elastic restraining projection which projects into the slot and is disposed at a distance from the slot end so as to assure freedom from clamping for the fastening screw. In a particular embodiment of the spacing plates disclosed in this specification the retaining projection or projections are spring tongues which, when the spacing plate is pushed onto the fastening screw, spring back into recesses provided in the slot edges. This type of spacing plate does not fall off the shaft of the fastening screw whilst the fastening screw is being screwed into the wall to secure the window frame to the wall.Whilst this spacing plate does not fall off the shaft of the screw it can, nonetheless, rotate about the shaft and thereby become oriented in a position which is different from that in which the spacing plate was initially put.
We have now developed a spacing plate which does not fall off the shaft of the fastening screw whilst the screw is being screwed through the window frame into the wall and, furthermore, remains oriented in the position in which it is placed originally.
Accordingly, the present invention provides a flexible spacing plate of substantially U-shaped construction which is adapted to surround a fastening screw or the like, wherein a portion of the spacing plate is resilient and does not lie in the plane of the U-shaped spacing plate, whereby on application of force to the non-planar resilient portion the spacing plate becomes substantially lamellar and flat, characterized in that the non-planar resilient portion is formed by at least one resilient hinge.
The spacing plates of the present invention are preferably made from a plastics material, such as polyethylene or polypropylene.
The non-planar resilient portion may form at least a part of one or both of the legs of the U-shaped spacing plate. Alternatively, the non-planar resilient portion may be provided in the closed end of the U-shaped spacing plate.
The non-planar resilient portion or portions is provided by one or more resilient hinges.
In use, the spacing plates of the present invention remain in the orientation in which they are placed over the fastening screws for fastening the window frame to the wall. The spacing plates are held in this position by friction between the nonplanar resilient portion and the window frame or the wall. When the window frame is screwed to the wall by means of fastening screws, a force is applied to the non-planar resilient portion, thereby causing the spacing plate to become substantially lamellar and flat.
The present invention will be further described with reference to the accompanying drawings in which: Figures 1 and 4 illustrate spacing plates having one or more resilient hinges.
Figures 1 and 4 illustrate arrangements in which one or more resilient hinges are provided in the U-shaped spacing plate. Referring to Figure 1, resilient hinges 8 of substantially V-shaped configuration are formed in each leg 2 of the spacing plate. The hinges 8 run the whole length of the legs 2 and meet the end 9 of the spacing plate remote from the slot 4. In Figure 2 a single hinge 10 is provided and this hinge essentially forms the body portion 3 of the U-shaped plate which connects legs 2 together. The hinge is of substantially V-shaped configuration. Figure 3 illustrates an arrangement in which the legs 2 of the U-shaped spacing plate themselves form the resilient hinges. The hinges are of substantially V-shaped configuration and are each hinged along line 11. Figure 4 shows an alternative type of hinge 12 which is formed at the edge of each of the legs 2 of the spacing plate. The hinges 12 are essentially of L-shaped configuration and are angled upwardly as shown in the Figure.
It will be appreciated that when the spacing plates illustrated in the drawings are used in the construction of windows, the application of force to the non-planar portions of the various spacing plates shown, during the fastening of the window frame to the wall by means of a fastening screw, will cause each of the resilient portions to flaten. In the arrangement shown in Figures 1 to 4 the V-shaped or L-shaped hinges will flatten.

Claims (4)

CLAIMS:
1. A flexible spacing plate of substantially U-shaped construction which is adapted to surround a fastening screw or the like, wherein a portion of the spacing plate is resilient and does not lie in the plane of the U-shaped spacing plate, whereby on application of force to the non-planar resilient portion the spacing plate becomes substantially lamellar and flat, characterized in that the non-planar resilient portion is formed by at least one resilient hinge.
2. A flexible spacing plate as claimed in claim 1 which is made from a plastics material.
3. A flexible spacing plate as claimed in claim 1 or claim 2 wherein the flexible hinge is of substantially V-shaped or L-shaped configuration.
4. A flexible spacing plate as claimed in claim 1 substantially as hereinbefore described with reference to and as illustrated in any one of Figures 1 to 4 of the accompanying drawings.
