Abstract

The cable store (1) comprises a base body (2) with two essentially opposed support surfaces (2a, 2b), coupled to each other in a spring elastic manner.

Description

cable holder

The invention relates to a cable holder according to the preamble of claim 1.

It is known to connect two separately arranged objects with the aid of connecting cables, for example in order to create an electrical or fluid-conducting connection between these objects. It is also known to store such connecting cables on a drum, with a partial length of the cable stored on the drum being pulled off or wound up depending on the respective spacing of the objects. This ensures that objects of different distances can be connected to the cable, the excess length of the

Connection cable is saved on the drum to save space and in an orderly manner.

Such cable holders have the disadvantage that they are relatively heavy and expensive, and are also only of limited use.

It is an object of the present invention to provide a cable holder which is simple to use and inexpensive.

This object is achieved with a cable holder having the features of claim 1. The sub-claims 2 to 10 relate to further, advantageously designed embodiments.

The invention is achieved in particular with a cable holder comprising a base body with two arranged essentially opposite one another Contact surfaces which are mutually resiliently coupled. The connecting cable is wound onto the base body in such a way that it rests on the base body at least in the area of the support surfaces. The connecting cable is preferably wound up in such a way that a particularly small force is exerted on the contact surfaces, so that the base body is slightly pretensioned and the two opposingly arranged contact surfaces exert an outward force on the connecting cable, which securely holds what is on the cable holder Cable section promotes.

At least a portion of the cable is usually always wound on a cable reel. In contrast to this, the cable holder according to the invention in a preferred application form does not have a coiled cable before it is used. The cable holder is used in this application to shorten a connection cable by winding a partial length of the connection cable onto the initially empty cable holder. The cable holder according to the invention has the advantage that it can be produced very inexpensively, that it can be used very flexibly, and that it can be used selectively where a shortening of a connecting cable is required.

The cable holder according to the invention has the further advantages that:

- The coiled cable has larger radii of curvature, which does not hinder the transport of a particularly gaseous or liquid medium, especially in the case of tubular cables.

- The first windings lying against the base body are only partially covered by the windings above, which is a

Visual inspection of the connecting line for damage or for proper transport of a fluid, for example, is facilitated.

- The cable holder has a low weight and therefore hardly loads the connecting line, even if a connecting line crosses a room without support and a cable holder is arranged in the room on this connecting line. - The cable holder is not a hindrance due to its size or weight, that it is also easy to handle and easily available, especially when they are needed several times and are to be carried in small pockets on the body.

- The cable holder allows easy extension or shortening of cables, so that no additional extension cables are required, which have to be connected or connected. Such a connection would hinder the transport of a fluid, since the connection points have a reduced cross section.

- Several cables can be kept neatly wound on separate cable holders and that there is no risk of knots forming.

- The cable is resiliently held on the cable holder. If the cable is subjected to tension, the cable holder can, due to its elasticity

Embodiment, deliver a partial length of the cable stored thereon, by tightening the cable section located on the cable holder more, and thereby reducing the length of the cable holder. This reduces the tensile force acting on the connecting cable or acting on a connecting element or a connection point of the connecting cable.

The cable holder according to the invention is suitable, for example, for use in the hospital area. For example, several cables, for example an electrical cable and a cable designed as an oxygen line, can be arranged on a hospital bed and are connected to a fixed socket. The hospital beds can usually be moved on rollers so that the length of these cables can be readjusted at each fixed location to prevent cable clutter. In addition, the cable holder according to the invention is suitable for receiving cables connected to a patient, for example electrical cables which serve to monitor cardiac activity, or fluid-conducting cables such as infusion lines or with wound areas connected hoses. The cable holder according to the invention can be designed in a wide variety of sizes, including very small ones, for example to hold thin electrical cables of a probe. The cable holder according to the invention is also particularly suitable for use in an intensive care unit or in an operating room, since it can be in various sizes, has a very low weight, can be used as a disposable product due to the low price, and is also inexpensive as a germ-free cable holder is available. A large number of cables can be present, with at least some cables being wound on the cable holder over a partial length, so that there is no disorder between the cables.

In the present application, the term cable is understood to mean a connecting line which is designed, for example, as a wire, an electrical cable or also as a hose for conducting a fluid.

The invention is explained using several exemplary embodiments. Show it:

1a is a perspective view of a cable holder;

Figure 1 b is a plan view of the cable holder.

1c shows a section through the cable holder along the section line A-A;

3g shows an embodiment of the guide elements.

In the following, the same reference number will be used for the same objects.

Fig. 1a shows a plate-shaped, flat and elongated

Cable holder 1 comprising a base body 2 with support surfaces 2a, 2b arranged on opposite end sections. The base body 2 also has a recess 3a, 3b on both sides in the region of the end sections with the formation of guide elements 2f. A cable 4 is wound relatively loosely around the base body 2 and held laterally by the guide elements 2f, only one turn being shown for the sake of clarity, but the base body 2 is usually wrapped with a plurality of turns. Fig. 1b shows a plan view and Fig. 1c shows a section along the line A-A of the same cable holder 1. The cable holder 1 has a longitudinal axis 2c. 1d shows a side view of the

Cable holder 1 from viewing direction B. In the side view according to FIG. 1e from viewing direction B, a cable holder 1 is shown, which is wrapped by a tightly arranged cable 4, whereby the base body 2, due to the forces acting on the support surfaces 2a, 2b and their forces resilient properties as shown. In the position shown, the base body 2 undergoes only an elastic deformation, the base body generating a spring force opposite to the deflection by the bending, so that the base body strives to assume the starting position shown in FIG. 1d. If the cable 4 is completely removed from the cable holder 1, this assumes the position shown in FIG. 1d. If, in the position according to FIG. 1e, the tensile force at the two ends of the cable 4 is reduced, the base body 2 moves back in the direction of the starting position, provided that the acting forces allow the cable 4 to be moved relative to the bearing surfaces 2a, 2b.

The cable holder 1 according to that in Fig. 1f with a side view

The direction of view B shown comprises a base body 2 with two part bodies 2d, 2e connected via a joint 2g. Two firm with The springs 2h connected to the partial body 2d each slide freely on one side on the surface of the partial body 2e. The joint 2g, the sub-bodies 2d, 2e and the springs 2h are arranged in a mutually opposing manner in such a way that the cable holder 1 has a resilient behavior and automatically changes into the position shown in FIG. 1f without an external load.

Fig. 2 shows an embodiment of a cuboid cable holder 1 consisting of an elastic base body with oppositely arranged, slightly curved contact surfaces 2a, 2b.

3a shows a top view of a further exemplary embodiment of a cable holder 1. In contrast to the embodiment shown in FIG. 1a, the cable holder 1 according to FIG. 3a has hook-shaped guide elements 2f, two guide elements 2f arranged opposite one another forming an opening 5. This hook-shaped configuration of the guide elements 2f has the advantage that a cable 4 is better held in the recess 3a, 3b. The base body 2 of the cable holder 1 can be designed with a wide variety of cross-sectional shapes. Figures 3d, 3e and 3f show examples of possible cross-sectional shapes of a section along the line C-C.

FIG. 3 b shows the same cable holder 1 as shown in FIG. 3 a, a cable 4 being wound around the base body 4. The additional holding function caused by the hook-shaped configuration of the guide element 2f on the cable 4 is also clearly visible, in that the cable 4 rests on the hook-shaped guide element 2f at the top and bottom.

3c shows the same cable holder 1 as shown in FIGS. 3a and 3b, the wound cable 4 of which has been or was subjected to a great tensile load at its ends, so that the cable holder 1 deformed elastically.

3g shows in a view from direction D a further possible embodiment of the hook-shaped guide elements 2f, in that adjacently arranged guide elements 2f at their end sections underneath Formation of a gap 5 are designed to run approximately parallel. The gap 5 in the exemplary embodiment according to FIG. 3g or FIG. 3a can be designed in such a way that its width is less than the cross section of the cable 4. The hook-shaped guide elements 2f have elastic properties, so that the cable 4 is slightly bent by the guide elements 2f can be inserted into the recess 3a, 3b.

The cable holder 1 is preferably made of a plastic or metal. The cable holder 1 can be manufactured in a wide variety of sizes. A small cable holder 1 can have an overall length of 5 cm, for example in the longitudinal direction 2c, whereas a larger cable holder 1 can have an overall length of 20 cm, for example. The base body can be made very thin and have a thickness of 1 mm, for example.
