Abstract

A fixing clip of plastics or bent metal wire has a first abutment means (eg limbs 2,3) and one or more second abutment means (eg limbs 1,4) connected by a respective connecting arm or arms (2,6). The abutment means (2,3 and 1,4) are substantially perpendicular to the plane accommodating the connecting arm(s) (2,6), and increasing the spacing between the first and second abutment means (2,3 and 1,4) gives rise to a gripping force by which the clip can be secured to the support. The sheet material can be located between at least one of the abutment means and the support. The support will usually comprise brickwork or blockwork, and the connecting arm(s) (2,6) will be disposed in a mortar layer between adjacent courses of masonry. Other shapes of the fixing clip are shown.

Description

TITLE: Fixing of Sheet Material DESCRIPTION The present invention relates to the fixing of sheet material to a structural support, for example in buildings or other structures.
In the construction of buildings or other structures there is a need to fix insulation material to the structure, typically to brickwork or blockwork walls or to timber framework. The insulation material may be required to provide temperature, noise, vibration, sound, light or radioactivity insulation/protection, or combinations of these or to act as a moisture barrier.
For convenience we refer hereafter to insulation material to cover such variety of applications. The insulation material may take the form of board, film, membrane or other sheet material. Generally speaking we use the term board for rigid or semi-rigid sheet material and the term film or membrane for a thin flexible sheet material. We use the term sheet material generally to cover all these.
The use of nails, screws or similar fastenings to fix the material to the structure may result in the puncturing of the insulation material. Depending on the type of insulation required this may reduce the insulation value of the material, or, depending on the nature of the material, structurally weaken it. When fastening to blockwork, brickwork, masonry or other material that cannot be readily nailed this fixing process also necessitates the drilling of fixing holes.
Such drilling is time consuming, requires hand tools which are often subject to theft from site and can have associated health and safety risks.
Although the use of adhesives may overcome these problems it is not suitable for use in all applications.
Furthermore, it takes time to cure, is relatively expensive and can have associated health and safety risks.
The present invention aims to provide a means of fixing, for example sheet material, which is suitable for many applications and which overcomes the disadvantages of the existing solutions.
Accordingly a first aspect of the invention provides a fixing clip comprising a first abutment means and one or more second abutment means connected to the first abutment means in spaced relation thereto, the first and second abutment means being disposed in one or more planes which lie substantially perpendicular to a plane accommodating the means connecting the one or more second abutment means to the first abutment means, and wherein increasing the at rest spacing between the first and second abutment means gives rise to a gripping force therebetween.
In use, at least a part of the structure with respect to which the clip is to be secured will be disposed between the first and second abutment means.
In one embodiment, the material to be secured with respect to the structure by the clip will be disposed between at least one of the abutment means and said structure. In another embodiment the clip is provided with additional engagement means for locating the material to be secured with respect to said structure.
In a preferred embodiment there are two second abutment means, each having a respective connection to the first abutment means. The two second abutment means are preferably in a common plane, or at least part of said two abutment means are.
Each second abutment means may comprise a single limb. The first abutment means preferably comprises two limbs which are connected together at one end and have their other end connected to a respective connecting arm of said connecting means.
The fixing clip may be made of any suitable material, including plastics, although a particularly convenient and economical material is metal wire which is sufficiently malleable to take a permanent set and yet which exhibits some resilience either in bending or torsion. For building applications a corrosion resistant material or coating is to be preferred.
Preferably the clip is formed by bending a single length of wire. In a preferred design applying a force to increase the separation of the first and second abutments imposes torsion upon the wire from which the preferred fixing clip is made.
It will be apparent from the above that the clip has a minimum of two points of contact with the supporting structure, and that contact may be direct or indirect. Usually the positioning of the clip will dispose the first and second abutment means adjacent opposing sides of the supporting structure.
In a preferred embodiment the first abutment means comprises a U-shaped element having two limbs and a connecting link. A respective connecting arm connects with each limb, for example by way of a 900 bend, and in turn each connecting arm connects with a respective second abutment means, for example by way of a 900 bend.
Each second abutment may comprise a single length of wire of predetermined length. In one embodiment the connecting link is relatively short and the two connecting arms are divergent as viewed from the first abutment means. In another embodiment the connecting link is long and the connecting arms are convergent - as viewed from the first abutment means. The connecting arms may be straight or bent.
In another embodiment, one or more of the limbs of the second abutment means may be provided with an extending finger. The finger is preferably disposed in a plane extending perpendicular to the plane in which the second abutment is disposed and usually parallel to the plane in which the connecting means is disposed. In use the projecting finger serves as a support for material to be secured with respect to the structure to which the fixing clip is applied.
Another aspect of the invention provides a method of fixing sheet material to a support structure using a fixing clip as hereinbefore described in which method a gripping force generated between the first and second abutments of the clip serves to hold the clip to the support structure.
In one embodiment the gripping force also serves to locate the sheet material with respect to the support structure. In another embodiment additional engagers are carried by the fixing clip and serve to locate the sheet material.
The present invention will now be described further, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a first embodiment of clip, Figure 2 is a perspective view illustrating the clip of Figure 1 in use for one application, Figure 3 is a perspective view illustrating the clip of Figure 1 in use for another application, Figure 4 is a side view of another embodiment of clip in use, Figure 5 is a perspective view of yet another embodiment of clip in use, Figure 6 is a perspective view of a still further embodiment of clip, Figure 7 is a perspective view of yet another embodiment of clip, Figure 8 is a perspective view of a clip similar to that of Figure 1 and showing an alternative way of accommodating it in use, Figure 9 is a perspective view of another embodiment of clip and showing another way of accommodating it in use, and Figure 10 is a perspective view of another embodiment of clip.
In the embodiment of Figure 1 a clip comprises a wire form incorporating limbs 1, 2, 3 and 4 which may be parallel with one another, two connecting arms 5 and 6 disposed in a plane at right angles to the limbs 1, 2, 3 and 4 and a connecting link 7. The connecting element 7 connects limbs 2 and 3, whilst connecting arm 5 connects limbs 1 and 2, and connecting arm 6 connects limbs 3 and 4. Thus connecting arms 5 and 6 are connected by the two limbs 2 nd 3 and the connecting link 7. It will be noted that the connecting link is at the opposite ends of the limbs 2 and 3 to the connecting arms 5 and 6. The above descried clip is formed by bending a length of wire. In the illustrated embodiment a respective returned end la, 4a is formed at the end of each of the limbs 1 and 2.
The clip of Figure 1 is intended to be located with respect to a supporting structure. Fitting of the clip relies on the fact that, as made, the distance, A in Figure 1, between the two parallel planes accommodating limbs 2, 3 and 1, 4 respectively, is less than the width of the supporting structure to which the clip is to be secured. In the illustrated embodiment, urging the limbs 1 and 4 toward one another serves to increase dimension A. In so doing torsion is imposed on limbs 2, 3. After placing the clip over the supporting structure, limbs 1, 4 are released and the effect of the residual torsion in limbs 2 an 3 cause the clip to grip the supporting structure disposed between the respective pair of limbs 1, 4 and 2, 3.
For the principal application the supporting structure will be a wall and typically will comprise courses of bricks or blocks. The connecting arms will be accommodated within the thickness of mortar between the course of brickwork or blockwork, etc. Figure 2 illustrates how the clip can be used to hold a sheet of insulation material 8 in place by trapping it between the spring clip 9 and the supporting structure 10. In the embodiment the sheet of insulation material is portrayed as a thin flexible film. By virtue of the fact that limbs 1, 2, 3 and 4 have a specific length, they serve conveniently and accommodating to facilitate the accurate delimitation of a void (II) between the insulation material and an adjacent surface 12 as is often required to meet certain insulation standards.
In Figure 3 the insulation material comprises a sheet with significant thickness. Here the sheet 8 is held between the limbs 1 and 4 and the surface of the supporting structure 10. Of course, the insulation material could be trapped between the limbs 2, 3 and the surface of the supporting structure. Where insulation is required to be applied to both surface of the supporting structure this can be readily accommodated.
The bent back ends la, 4a provide a convenient means of applying finger pressure to the clip to facilitate position and repositioning. In addition the use of bent back ends is advantageous in avoiding accidental puncturing of the insulation material.
The limbs 1 and 4 are shown as being disposed in parallel relation, as are the limbs 2 and 3. This is not essential, although it is preferable for the limbs 1 and 4 to be in a common plane and for the limbs 2 an 3 to lie in a different common plane. Usually those different common planes will be parallel to one another.
The ends of the limbs 1 and 4 may be modified to provide other convenient methods of fixing insulation material to the structure. For example in Figure 4 respective ends of the limbs 1 and 4 have horizontally extending fingers 14 and 15 respectively and rigid insulation material 8' is supported upon those horizontal extending fingers. Conveniently the free ends of the fingers are upturned as at 16 to assist in retention of the insulation material. The clip 9' is accommodated in the jointing of the blockwork supporting structure 10.
In Figure 5 the insulation material 8' is impaled upon the extended fingers 17 and 18. Note that the upturns 16 are omitted and that in the embodiments of Figures 4 and 5 the fingers extend perpendicular to the surface of the supporting structure and consequently are in a plane which is parallel to a plane accommodating the connecting arms 5 and 6. It will be understood that for certain applications it is immaterial whether the connecting arms are disposed in a horizontally or a vertical plane.
Figure 6 illustrates an alternative embodiment of clip. It has the same basic elements as the clip of Figure 1. However, the connecting link 7' is extended to provide a larger bearing length on the insulation material 8". The length is increased to such an extent that rather than the limbs being arranged to diverge away from one another as viewed in a direction towards their free ends which carry limbs 1 and 4 they can be arranged to converge, so that the overall width of the clip is not increased beyond the length of the connecting limb 7'. Of course, with such an embodiment, the limbs 1 an 4 are moved away from one another to increase the distance A between limbs 1, 4 and 2, 3 for positioning purposes.
Figure 7 illustrates an alternative embodiment of clip which comprises multiple clip elements formed from a continuous length of wire. The basic element corresponds to the clip of Figure 6 but each clip element is connected with an adjacent clip element by a further connecting link 7", disposed between limbs 1 and 4 of adjacent clip elements. Of course, the clip illustrated in Figure 1 may form the basis for a multiple element clip by forming a connecting link between limb 4 and limb 1 of an adjacent clip. Such multiple element clips may be used for fixing insulation material along the length of a structural edge.
Figures 8 and 9 illustrate alternative ways of accommodating the clip in use. In Figure 8 the clip is of the type shown in Figure 1 and a hole 19 is formed in the structure support member (eg. blockwork) 10 and receives the limbs 2 and 3. In Figure 9, a groove 20 is provided in the structural support material 10 and receives the limbs 1 and 4 of the clip 9. Note here the arms 5, 6 splay outwardly from the limbs 2, 3. This is an alternative to the embodiment of Figure 8.
Referring now to Figure 10, here we illustrate an embodiment of the invention which has a first abutment 1" and has just one second abutment 2". The connecting arm between the first and second abutment comprises a bent arm having limbs 5a and Sb. Bending occurs in the arm to generate a gripping force between the first and second abutments. The second abutment includes limbs 2a and 2b to provide line contact with the insulation material to be secured.
The possible clip variants are not limited to the illustrated embodiments.
