RACK FOR HANGING THE KNIFE SHOULDER - STROPP FOR UPPER HANDLING

AV EN KNIVSLIDA.

The present invention relates to a rack for hanging a knife sheath, which rake is made of a flexible, rigid plastic material.

In recent years, leather in knives and knife sheaths has been replaced by a plastic material, such as polypropylene. One disadvantage of scaffolding made of such a material is that the sling bends only against its plane and, when connected to the knife sheath, does not bend downwards, for example when seated in a car, with the result that the sling can break and cause difficulties for the wearer.

The main object of the invention is thus to provide a sling which can be easily bent or oriented in its plane, which causes the sheath to turn forwards or backwards when subjected to a force.

Another object of the invention is to provide a rack which is furthermore easily bendable in the plane of the rack around the axis even when using a very rigid plastic.

These objects are fully realized by the invention as defined in the claims.

In the following, the invention will be explained in detail with reference to the accompanying drawing, in which

Fig. 5 shows a modified embodiment of the invention.

Figures 1 and 2 show a sling 1f which is a flexible, substantially non-stretchable and relatively rigid plastic material such as polypropylene. The rack consists of a substantially planar, uniformly thick plate cut by a corrugated part 2. Three corrugations are shown here, namely corrugations 3, 4 and 5, but the number may vary. In the corrugated part 2, the "bellows" have shafts for each corrugation 3, 4, 5, which shafts are oriented perpendicularly or at least substantially perpendicular to the longitudinal axis of the carcass 1 and preferably extend over the entire width of the carcass. As illustrated in Figure 3, these corrugations allow the rack to bend in the plane of the rack. The corrugations 3, 4, 5 have walls, which are most preferably thinner than the suspension part 7 terminating in the corrugated part of the carcass, which is provided with elongate, axial openings 8, 9 for a seat belt or the like. An upper bend is formed in one opening for hanging on a button. In order to facilitate bending in the plane according to Fig. 3, it may be suitable to reduce the stiffness in the corrugations 3, 4, 5 not only by making them thin-walled but also by arranging a weakening groove, e.g. gutters 10, 11, 12. is arranged above the corrugated part 2 in the embodiment shown in Figures 1, 2, 3, facilitating the outward bending of the sheath 15.

The corrugated part 2 will in fact form a spring, 3 77797 which stretches and one or more substantially inextensible members are arranged between the upper, substantially inextensible part 1 of the rack and the knife sheath 15 shown in Fig. 1 to prevent elasticity. Figures 1, 2, 3 and 4 show this non-stretchable member which receives the weight of the sheath 15 and the knife arranged inside it and which consists of a strip 16 connected by corrugations or pleats and passing through the entire corrugated part 2 in the middle thereof. The wide side surfaces of the strip 16, the cross-section of which is shown in the figures as rectangular, are directed towards the side edges of the sling and therefore form the smallest possible bending resistance in the plane of the sling. However, it is possible to use several tendons or the like which receive the load in the direction of the center line 6, and these tendons do not necessarily have to be of the same material as the slings in general, but can be made of metal wires or the like cast in and descending 1 and the knife sheath 15.

Figure 5 illustrates a modified embodiment in which the previously described strip 16 has been replaced by an hourglass-shaped tendon 17 with a circular cross-section. The tendon 17 is surrounded by two openings 18, 19 extending over the entire corrugated part 2. The shape of the tendon is adapted so that the lowest bending stiffness occurs in the middle part of the part 2. Of course, it is also possible that in the embodiment according to Fig. 4 a flat strip with a rectangular cross-section and a surface plane oriented perpendicular to the plane of the carcass 1 is used and it is also possible to make a load-bearing tendon in the embodiment according to Fig. 1. It has been assumed above that the corrugations are V-shaped or substantially V-shaped, but it is also possible to form a cylindrical surface in them.
