DE20307430U1 - Cable holding shackle is provided as wire bending unit, whose retaining area is formed by spring coil like winding of wire - Google Patents

Abstract

The shackle has a central retaining area (3) for fastening elements. Shackle sides (5) join the retaining area and are pretensioned against the background in the standard mounting position. The shackle is provided as a wire bending unit (9), whose retaining area is formed by a spring coil like winding (12) of the wire or by shaping of the wire, which are parallel to the axis of the fastening elements.

Description

The invention relates to a cable retaining bracket for holding one or more cables running parallel to one another on a substrate, such as walls, ceilings, floors or similar abutments, with a centrally arranged receiving area for fastening means, wherein diametrically opposed bracket legs adjoin the receiving area, which are pre-tensioned against the substrate in the desired mounting position, wherein the cable retaining bracket is designed as a bent wire part.

Such a cable retaining bracket is described in the older utility model application file no.: 203 05 948.4. An essential aspect of the cable retaining bracket according to the invention is that it is designed as a bent wire part, so that it can be used in particular

can be manufactured cost-effectively and is also suitable and intended to hold corresponding cables or the like in the correct position over a longer period of time in the event of fire.

In order to enable such cable retaining brackets designed as bent wire parts to be easily fastened, for example with impact dowels or impact screws, by inserting the impact dowel or the like into the receiving area and acting on the head of the corresponding fastening element with a hammer without parts of the cable retaining bracket interfering, it is proposed that the receiving area of the bent wire part be formed by a helical spring-like winding of the wire or by formations of the wire that form the bent wire part and are directed axially parallel to the fastening means.

It is particularly preferred that the first end of the winding lies in the plane spanned by the upper side of the bent wire part, and the second end of the winding rests on the mounting surface or can be placed on it.

Furthermore, it is particularly preferably provided that the bent wire part has bracket legs which are pre-bent from the receiving area to the mounting plane, wherein the free ends of the bracket legs are approximately at the height level which is spanned by the second end of the winding.

In order to ensure smooth operation and to provide a torsion axis for the spring-loaded bracket legs, it is provided that the winding at the first end passes over a web directed transversely to the longitudinal extension of the cable retaining bracket and over an angle into a wire area that forms one longitudinal web of a bracket leg, and at the second end passes over a transverse web, a longitudinal web, a vertical web and an angle into a wire area that forms one longitudinal web of the second bracket leg, which longitudinal web runs in the extension direction of the other longitudinal web.

An embodiment of the invention is shown in the drawing and described in more detail below.
It shows:

Figure 2 also seen in plan view, Figure 3 the cable retaining bracket in isometric

oblique view;
Figure 4 shows the cable retaining bracket in front view.

The drawing shows a cable retaining bracket 1 for holding one or more cables running parallel to each other.

For this purpose, the retaining bracket can be fastened to a surface not shown in the drawing by means of a fastening means which passes through the receiving area 3. Diametrically opposed bracket legs 5 are connected to the centrally located receiving area 3, which are of the same shape and may be wavy in order to ensure that cables or the like to be held are securely positioned.

The cable retaining bracket 1 is designed as a bent wire part 9, which is formed from a wire section. The receiving area 3 of the bent wire part 9 is formed by a helical spring-like winding 12 of the wire that forms the bent wire part. The first end of the winding, which is at the top in the drawing figure 1, lies in the plane that extends from the top of the bent wire part 9 close to the receiving area 3.

is clamped, while the second end of the winding 12, which is at the bottom in the illustration according to Figure 1, rests on the corresponding mounting surface or can be placed against it. The bent wire part 9 has bracket legs 5 which are pre-bent from the receiving area 3 to the mounting plane, the ends of the bracket legs being bent upwards to form an insertion bevel. The free ends of the bracket legs 5 lie in front of the bend forming the insertion bevel at approximately the height level spanned by the second, lower end of the winding 12. This arrangement and design ensures that a fastening element which is introduced into the receiving area 3, for example a hammer dowel or an impact screw, can be properly driven in and fastened by means of a hammer blow, without parts of the cable retaining bracket 1 getting in the way. The head of the fastening element is easily accessible above the winding 12 in the receiving area. In order to achieve a smooth operation of the cable retaining bracket 1 when inserting the cables and also to be able to exert a sufficient pre-tension on the inserted cables, the winding 12 is connected at the upper end via a web 13 directed transversely to the longitudinal extension of the cable retaining bracket 1 and via an angled portion 14 to a wire area which forms one longitudinal web of a

bracket leg 5. The area 13 essentially forms a torsion axis around which the bracket legs can move. At the second end of the winding 12, i.e. at its lower end, there is a transverse web 15, a longitudinal web 16, a vertical web 17 and an angled portion 18 which merges into an area of the wire which forms one longitudinal web of the second bracket leg 9. The two longitudinal webs of the two bracket legs 9 are essentially arranged in the extension direction of one another. Here too, the web 15 forms a torsion axis for actuating the bracket leg 9. In particular, the fact that the cable retaining brackets are made of metal wire ensures that they can retain their function even if a large amount of heat develops in a room equipped with them, for example in the event of a fire.

It should also be noted that the winding 12 serves as a guide when inserting the fastening means, wherein the turns forming the winding 12 preferably lie against one another without a gap, in particular when the corresponding fastening means is driven through the receiving area 3 into the corresponding substrate.
