Description

I

TITLE: Cayping System For Cable The present invention relates to capping system for cable (the term cable also includes pipe herein).

When a new building is built or any electrical wiring/re-wiring is undertaken, numerous types of cable, such as mains electrical cable, is first laid out adjacent Walls to bi connected to electrical sockets and the like. Capping is then applied to cover the cables and secure the cable to the surface of a wall whilst also offering protecting to the cables when the walls are being plastered. Walls are then plastered over covering the capping and within the protected cables.

The capping is often made of a simple U-shaped fabrication of plastic or metal which is secured to the walls by using screws or nails that typically puncture through the flanged edge of the capping to secure it in place.

It is often difficult to keep the cable in the hollow section of the capping whilst securing the capping to a wall, and often a screw or nail can be passed through the cable by mistake. Often this mistake is not realised until after the walls have been plastered resulting in very costly and time consuming measures to rectit' the damaged cables.

The invention seeks to provide a solution to this problem whilst providing a much quicker and efficient method when installing cable capping systems.

The capping system may also be used to cover pipes as well as cables.

According to the present invention there is provided a capping system for cable comprising: a) a length of generally U-shaped capping having a base, and side walls extending from the, base, b) fixing apertures in the base at spaced intervals along the base, and c) and a plurality of spacers, each spacer allowing a fixing through a fixing aperture, and a cable securement device to secure cable to the capping, in use, cable can be placed in the U-shaped capping and secured to the capping using each securement device, and the capping placed against a wall and secured to a wall with a fixing passing through spacer hollow cores.

Preferably each spacer has a hollow core to receive a fixing through the spacer and through a fixing aperture, and a cable securement device to secure cable to the capping.

in one embodiment the spacers are grommets each having a tail to insert in and secure to a fixing aperture and the cable securement device is a head on the grommet to secure the cable between the head and the capping.

Preferably the grommet head includes a groove between which cable can lie and the entrance to the groove is adapted to be blocked by a side wall or base of the capping to secure cable between the grommet head and a capping side wall. The groove may be an annular groove.

Preferably the capping side walls have a flange extending from their free edges to abut a wall.

Preferably the grommet tail has a deformable tip to allow the grommet to be releasably secured to the capping base prior to a fixing securing the capping to a wall.

Preferably the grommet tail tip permanently deforms when the capping is secured to a wall to keep the grommet permanently secured to the base. Preferably the grommet tail tip is deformed when it is squeezed between the capping base and the wail to keep the grommet permanently secured to the base.

Preferably the system further comprises caps to fill base grommet apertures which do not receive grornmets.

In one embodiment the spacers are grommets each having a tail to insert in and secure to a fixing aperture and the cable securement device includes one or more U shaped recesses or clips to receive cable.

In another embodiment the spacers are secured to the capping adjacent a fixing aperture. The cable securement device includes one or more U shaped recesses or clips to receive cable.

An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a perspective view of a piece of capping with a pair of cables.

Figure 2A shows a cross section of the cables and capping prior to insertion of a grommet, Figure 2B shows a cross section of the cables and capping alter insertion oh grommet, and Figure ZC shows a cross section of the cables and capping after insertion of a grommet and securement of the capping on a wall.

Figure 3 shows a perspective of an alternative embodiment, and Figure 4 shows a perspective view of another alternative embodiment.

Refening to the drawings there is shown a capping system 1 for cable X,Y.

System 1 has a length of generally U-shaped capping 10 formed from metal or plastics.

Capping 10 has a base 11, and side walls 12,13 extending normal from the base. Upper free edges of the side walls include outwardly extending flanges 12A,13A to abut a wall Z (see Figure 2C).

A Plurality of grommet apertures 14 are provided in the base at spaced intervals along the base 11.

A plurality of grommets 20 is provided. Each grommet having a tail 21 to insert and secure the grommet in a grommet aperture, a hollow core 22 to receive a fixing through the grommet and through a grommet aperture, and a head 23 to secure cable between the grommet head and the capping 10.

Grommet head 23 includes an annular groove 24 between flanges 23A,23B in which cable X,Y can lie and the entrance to the groove is adapted to be blocked by a side wall of the capping to secure cable between the grommet head and a capping side wall (see Figure 2B and 2C).

The grommet tail 21 has a deformable tip 25 made of four quadrant shells 25A,25B,25C,25D to allow the grommet to be releasably secured to the capping base prior to a fixing securing the capping to a wall (see Figure 2B). The grommet tail tip 25 permanently deforms when the capping is squeezed between the capping base and the wall to keep the grommet permanently secured to the base (see Figure 2C) when a fixing such as a screw 30 is inserted through the hollow core 22 and screwed into a wall Z. In use, cable can be placed in the U-shaped capping and grommet tails inserted in grommet apertures to secure the cable to the capping, and the capping placed against a wall Z and secured to a wail with fixing 40 passing through grommet hollow cores 22. In practice it may be easier to insert the cables X,Y in the groove 24 and then placing the cable and grommet into the capping rather than trying to insert the grommet into the U-shaped capping with the cables already in the U-shaped capping (as shown in Figure 2A). Also the flanges 23B may be of an equal size to flange 23A.

Preferably the system further comprises caps not shown) to fill base grommet apertures 14 which do not receive grommets.

It is envisaged that lengths of capping and grommets would be sold for eleciricians to use.

The grommets and capping may come in different sizes to suit different sizes of cable. The capping may also be used to cover pipes.

When installing the capping, the capping with the grommet hollow cores 22 will serve as a guide for drills or nails. The hollow core may typically be 6.5mm in diameter.

Referring now to Figure 3, there is shown a capping system 30 for cable X,Y. Capping system works in a similar way to the capping system described above with reference to Figures l,2A,2B, and 2C.

System 30 has a length of generally U-shaped capping 40 formed from metal or plastics.

A plurality of grommets 5Ois provided. Each grommet has a tail 51 to insert and secure the grommet in a grommet aperture, a hollow core 52 to receive a fixing through the grommet and through a grommet aperture, and a cable securement device in the form of a pair of U-shaped recesses 53A,53B to secure cable.

The grommet tail 51 has a deformable tip made of two hemispherical shells 54A,54B to allow the grommet to be releasably secured to the capping base prior to a fixing securing the capping to a wall. The grommet tail tip 51 permanently deforms when the capping is squeezed between the capping base and the wall to keep the grommet permanently secured to the base when a fixing such as a screw is inserted through the hollow core 52 and screwed into a wall.

In use, cable can be placed in the U-shaped capping and grommet tails inserted in grommet apertures to secure the cable to the capping, and the capping placed against a wall and secured to a wall with fixing passing through grommet hollow cores 52.

Referring now to Figure 4, there is sho a capping system 60 for cable X,Y. Capping system works in a similar way to the capping system described above with reference to Figures 1,2A,2B, 2C, and 3.

System 60 has a length of generally U-shaped capping 70 formed from metal or plastics.

Capping 70 has a base 71, and side walls 72,73 extending normal from the base. Upper free edges of the side walls include outwardly extending flanges 72A,73A to abut a walL A Plurality of fixing apertures 74 are provided in the base at spaced intervals along the base 41.

A plurality of cable securement means are provided in the form of a pair of clips 81,82 each with U-shaped recesses 81A,82A. Clips 8 1,82 may be permanently positioned on the capping base 71. Clips 81,82 are spaced apart either side of fixing apertures 74 so that a fixing such as a screw or nail can be passed through fixing aperture 74 to secure capping 70 to a wall.

In use, cable can be placed in the clips 81,82 to secure the cable to the capping, and the capping placed against a wall and secured to a wall with a fixing passing through fixing apertures 74. If desired clips 81,82 could bejoined together by a bridging member with an aperture (in line with an aperture 74) to act as a drill guide.
