Description

Elastic tension spring to generate counter-tension on the strands of jacquard harnesses

The invention relates to a rubber tension spring for generating the counter-tension on the braid * of Jocquard harnesses, which both to be attached to the strands as well as near the ground. B ^ i the use of such known elastic tension springs has the problem of their attachment to the strands as well as in the area of the soil. The simplest connection through a knot does not have sufficient builder strength, as tears occur at the knot, which close after a very short period of time Cause destruction. A lateral clamping of the elastic tension spring on the stranded wire or on a hook, as has already been carried out, has the disadvantage that the center lines of strands, elastic tension spring and hook are offset from one another, which leads to sohrag positions. One has already tried to remove the butt butted ends]

Tension springs and hooks through the ends of the plastic tubes that cross the tails to be connected by means of shrink-fitting or encapsulation. This process is very time consuming and expensive as for a medium harness approx. 6000-10000, and with a very tight setting up to 20,000, rubber springs are used Need to become.

According to the German patent specification 1 196 585 it is also known, the ends of the rubber spring between two turns of a To clamp the helical spring and use the latter as an attachment member. Apart from that, this is not the case with this version the desired open loop shape can be achieved, is the case with very tight armor, as one would find in the Silk weaving used, not possible because of the windings of the Apply a relatively large amount of Rauii to the coil spring. Since in operation with a rotating movement of the windings around the litz eye must be expected, the previously known arrangement requires the same space as a ball with the diameter of the turns.

The invention is therefore based on the object of avoiding these disadvantages of the above-mentioned devices and a simple one To find the connection between the rubber spring and stranded wire on the one hand and the attachment in the area of the floor on the other hand, the is easy to manufacture and interchangeable and which takes up very little space in order to be able to use it for very tight armor to be able to.

The essence of the invention is that the elastic tension spring is designed as a hose, in the ends of which the end

a stranded wire and / or the extended end of a fastening element, zE a hook or the like, can be pushed in and fastened. Such a connection by pushing the strand end or the hook end into the hose is easy to produce and requires very little space during operation, An. the tube is only slightly thicker than the strand itself.

The connection between the hose and the stranded wire or the respective fastening element can be made within the scope of the invention done in different ways. In a simple embodiment of the invention one also already obtains one after very long endurance tests always nooh firm connection due to the adhesion of the itself as a result of its elasticity to the circumference of the strand or the circumference of the inserted Part of the fastening element pressing Ouromisoblauch. In a further development of the invention, it is of course also possible that the sole tube on the braid and / or on the fastening element by gluing. Also a fastening by means of a hose and braid and / or hose and Fastening element Clamping element pushed over, e.g. in the form a sleeve or the like., Possible according to the invention. In further training the invention can also provide that the ends of the strands and / or the fastening element roughened or are profiled accordingly, so <* ate the inner wall of the Hose can adhere even better to this roughened or profiled surface.

The invention is shown in the drawing by way of example and schematiacb.

Fig. 1: The attachment of a rubber hose to two

Hook and Fig. 2: the attachment of a rubber hose. the strand.

In the drawing, two execution commands are shown in side views. "Pig.1 shows a rubber sole 1, in the ends of which the ends of hooks 2 and 5 are inserted, hook 2 is linked, for example, by gluing with the Gummiechlaunh, while hook 3 duroh pressed on

\ Terminal 4 is connected to the rubber soleplate. These hooks

j are on the one hand in the eyelet at the lower end of the strand 5

and at the end near the ground in a rod 6, which is in the example shown perpendicular to the drawing plane runs, hooked.

Instead of a connection by gluing or with the help of a

Clamping element 4 can in the context of the invention, the connection of Rubber hose and hook also by wrapping with a cord getting produced. As already mentioned, with suitable coordination of the bore of the rubber loop on the circumference of the The wire and the outer diameter of the hook end determine the adhesive force both parts must be so large that this connection is sufficient for safe operation. This is shown simple adhesive connection in that the ends to be inserted are not smooth, but roughened, corrugated or otherwise be formed profiled in a suitable manner.

Although the eyes of the hooks are kept very small in diameter there may not be enough space available for this in special cases with very tight harnesses. For such Cases the invention proposes according to Figure 2, the end of the T / itze not as an eyelet, but smooth or in some other way profiled and train it without the interposition of a The hook directly into the rubber hose. For the in the area of the ground at the lower end of the Gumrois tube However, there is always enough space to be attached to the hook Disposal.

With the basic idea according to the invention of providing the rubber spring at least in the area of its ends with a hole running in the direction of the strand, into which a part of the element to be attached to the spring can be pushed and fixed therein by adhesion, gluing or clamping. <* Rd thus achieved a very easy to produce and low ^v iatz beanspruchende connection between the strand and the Cdgenzugfederelement. From the above information it is readily apparent to the person skilled in the art that this idea de Rrfinduns; also in further execution forms, rmevi vervM ^ kI, h be Vanni In particular, it is of course also possible in the paralyzing dex equivalence to use a material made of a different material but similar in its elastic properties instead of a Sen Laue es pih rubber. The invention is therefore not restricted to the exemplary embodiments shown.
