Abstract

A device 4 for supporting cables, ropes or rods which are passed through an opening 2 in a flat structural member 1 consists of a support part 6 with an overlay 7 and two compensating parts 8 which are insertable or affixable into the support part 6. The compensating parts 8 are secured onto the edge 3 of the opening 2 by means of spring clips 17 and may be forced against the edge 3 by spring action, be screwed into the support part by means of a threaded plug or be provided with a smooth plug which is clamped fast in a slotted tube end of the support part by a clip. <IMAGE>

Description

SPECIFICATION A device for supporting cables, ropes or rods in openings This invention relates to a device for supporting cables, ropes or rods which are passed through an opening in a flat structural member.

Such supporting devices are needed in great numbers particularly in aircraft construction to enable passage of cables and wiring for the electrical equipment or control ropes, tubes, and rods through the openings or lightening holes in flat structural members (usually known as primary structures), such as girdersr bulkheads and walls.

Known supporting devices consist of several parts that have to be connected together, such as attachment brackets, cable mountings and pressure plates, which are specially adapted to the particular diameters of each opening and are bolted or riveted to the flat structural members.

An object of the invention is the provision of a simplified supporting device which does not need to be permanently connected to the- relevant opening and which is usable for a fairly wide range of different diameter openings.

In accordance with the invention, this object is achieved by provision of a device for supporting cables, ropes or rods which are passed through an opening in a flat structural member comprising a support part for the cables, ropes or rods into which two compensating parts are insertable or affixable, the compensating parts being provided at their respective ends with clips for attachment to the edge of the opening of the flat structural member.

Advantageously the support part is formed with a longitudinal bore and one or both of the compensating parts may be inserted therein. After insertion of the compensating parts into the support part the device in accordance with the invention is conveniently clamped fast to the edge of an opening by means of spring clips. The compensating parts may be spread apart by a spring arranged in the bore of the support part.

Alternatively, at least one of the compensating parts may be screwed into the support or held fast in its position by a conventional clamping ring.

By using a resilient material, such as foam material, as an overlay to the support it is possible to fasten cables, wiring or ropes of different thicknesses thereon by means of a cable binder.

The invention will be described further, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a side view of a first embodiment of the device of the invention for supporting cables or ropes which is inserted into an opening of a flat structural member; Fig. 2 is a partially sectioned plan view of the device in accordance with Fig. 1 having a spring for spreading apart the compensating parts; Fig. 3 is a partially sectioned plan view of a similar device having respectively one screwed-in and one clampedfast compensating part; and Fig. 4 is a side view of a second embodiment of the device of the invention having three compensating parts Fig. 1 shows a flat structural member 1, for example a transverse beam, having an opening 2 with a reinforced edge 3.As shown in Figs. 1 and 2 a first embodiment of a device in accordance with the invention comprises a device 4 which is clamped into the opening 2 and consists of a support part 6 having an elastic overlay 7 of resilient materialçsuch as foam material, as well as two identical compensating. parts 8. It is evident from the plan view of Fig. 2 that the compensating parts 8 are inserted into a bore 12 provided in the support part 6 and are forced apart by a spring 13 disposed between them in the bore 12. At each side of the overlay 7 the support part 6 has a respective groove 14-for a cable binder (not shown). The compensating parts 8 each have a plug 15 which slides in the bore 12 and is provided at its end with a projection 1 6 of smaller diameter over which the spring 1 3 is received.

That end of each compensating part 8 which protrudes out of the support part 8 is provided with a spring clip 17 which is shaped internally in accordance with the edge 3 of the flat structural member 1.

In a modified device, as shown in Fig. 3, the compensating part 9 which is shown on the right has a threaded plug 20 which is screwed into a threaded bore 21 of the-support part 6. The compensating part 10 shown on the left-hand side has a continuously smooth plug 22 which is held fast in the support part 6 by means of a clamping ring 23 which is placed around an outer tube part 23. which is provided with slots 24. According to requirements, either one of each of the compensating parts 9 and 10 or else two of-the same compensating parts 9 or 10 can be inserted into the support part 6.

In a second embodiment of the device of the invention, as shown in Fig. 4, apart from the two compensating parts 8 (or alternatively, but not shown, 9 or 1 0), a further compensating part 11 is provided perpendicularly to the support part 6.

This compensating part 11, which may, for example, be welded to the support part 6, consists of a bush 30, into which a plug 31 is inserted, the plug 31 being held optionally by means of a thread 32. In the same way as the compensating parts 8, 9 and 10, the plug 31 is clamped fast on the edge 3 of the flat structural member 1 by means of a spring clip 17. The plug 31 can also be designed without the depicted thread 32, in which case it is either forced against the edge 3 by means of a spring, as in the case-of the compensating part 8, or it is clamped fast against the bush 30 by means of a-clamping ring 23, as in the case of the compensating part 10.

In Fig. 4 various cables 33 are shown fastened on the overlap 7 with a cable binder 34 which is placed over the grooves 14 (see Figs. 2 and 3) serving to retain these cables on the overlay 7.
