for the axial securing of ropes

Waves or the like. "

For axially securing ropes on! Skins or also in Holes of housings or the like. are usually open, horseshoe-shaped resilient rings used, which in a Has the! / Hurry or the hole to intervene or directly jam the bar on the shaft young happens here by the fact that the same as a whole be bent apart or together. You have the Bach part of the fact that the forces of suspension are the Hingquersohnite strong beans «

Ss is also an open, resilient locking ring known, which consists of an outer and an inner ring part consists, with the inner -tting part in individual segments is subdivided with the outer iting part by radial Webs are connected .- ^ in such is however due to it unsymmetrical, open execution relatively unstable and can only absorb relatively limited forces.

Closed circlips are also used, with bent rings that jam on the shaft resilient, tongue-like! 'ropes are provided. However, they have / rings Pedering properties and damage in the Usually the surface of the waves. You can often do without it Destruction of the song is not removed again from the v / elle will.

In contrast, the invention aims above all to provide a Sieherunge ring, which combines the "advantages of the closed and the open locking rings" in FIG to have their "disadvantages, in particular in such a way that he at! spontaneous generation of a powerful clamping effect uno relatively low stress has a large spring area and also without destroying the ring or damaging it the "ι- / rush can be removed again. The invention exists accordingly essentially in the fact that the ring is a closed one Has ring part and resilient clamping elements through which in the circumferential direction extending or arranged recesses are partially separated from the ring part in the radial direction. Two clamping elements are preferred here provided, which is approximately semicircular over almost 180 ° extend and are diametrically opposed to each other.

With a locking ring designed according to the invention are made by clamping on the shaft or a

corresponding clamping forces occurring in the ring body self absorbed and balanced, without this himself

is noticeably deformed. The sing can thereby also be essential higher than an open ring. As a result of the more or less separated radial part from the closed ring part as well as tangential stretching of the clamping elements these have a relatively large suspension option on, on the other hand a connection of each of the clamping elements by two webs with the closed ring part prevents undesired rotation of the clamping elements out of the plane of the ring and ensures the desired stability. By appropriately dimensioning the ring and by appropriately shaping the terminal leine nt e, the ]? range of changes depending on the requirements within part limits enlarged or reduced. As a result is It is also possible to use the Hing with a correspondingly large lederungshub into a very deep! Tut without as is the case with the usual rings of the IPaIl, the elongation limit is exceeded.

The ring designed according to the invention can thus, depending on the dimensioning, be inserted into an annular groove in the shaft or, if it is harder ! Suspension, be placed directly on the Uelle, in such a way that it locks itself automatically on the shaft when loaded, but is nevertheless easily detachable again.

In the simplest version 'the clamping elements in the Lie in the ring plane. Another, in terms of the clamping

effect, possibly particularly beneficial execution äich results if the sing is bent as a whole or if the pinch duck is bent to the side from the plane of the hinge are. In order to achieve an even load, the closed outer part can be located between the connectors the terminal has a linear cross-section, two-dimensionally steady, tapering η.

In the drawing, two embodiments of the invention are shown, namely pointers

form of the invention, ^ 'ig «4 a section along line 4—4 of Fig. 3

The circlip according to J ^ ig.l and 2 consists of the outer closed! ring part lo, which outside the Connection points with the clamping elements essentially: has a uniform cross-section over the circumference are closed singing part, with this consist of one piece ^ the two resilient clamping elements 11 and 12 tied together. These consist of the radially directed, web-like cables 13a, 13b or 14a, 14b and the tangential cables directed tongue-shaped ropes 15a, 15b or «16a, 16b. The latter in pairs form an essentially

Ring parts r '

union semicircular singing part, this / on the inside limited by the semicircular contact surface 17 and 18 while they are on their outside through T-shaped recesses 19a and 19b and through between the webs 13a, 13b and 14a, 14b arranged holes or other openings 20 and 21 of the closed ring part 10 largely are separated.

If the sing is pushed over a ¹ JeIIe, which has a slightly larger outer diameter than the central opening 22 delimited by the circular edges 17 and 18, the clamping elements 11, 12 position themselves somewhat due to their pedestrian properties according to the diameter difference compared to the plane of the hinge obliquely, as a result of which they jam on the Ί / elle when pressure is exerted on them from that sighting which is opposite to the inclination or bending of the clamping elements.

Also in accordance with greatly resilient formation of Hinges or its clamping members, the ring in such a ^7: / elle pushed, that the u'berschiebens strongly laterally auebie-constricting clamping elements in a groove on the ¥ elle deflect during such that they are still supported on the base of the hat after springing back with peder pressure

The Pig embodiment. 3 and 4, τοη differs from that according to Pig. 1 and 2 on the one hand in that the

Hing part Io between the connection points of the webs 13a, 13b and 14a, 14 "b of the Elemmelemente 11,12 not uniform Has cross-section, but in these sections after the middle points 23a, 23 "b to both sides gradually rejuvenate. The tapering is achieved, for example, in that in the case of a - ^ external Hadius 2. with the center M 8, on the i-axis of the hanging the inner boundaries of the two liing sections have a radius r, the centers of which m outside the axis M, namely to lie on the side of the associated hanging section.

A further difference compared to the embodiment according to J? ^{Ig, 1 is that - as Ju 1} Ig · 4 shows - the clamping elements 11 and 12 with the tongue-like ends 1 a, 15 b, 16 a, 16 b from FIG Singing plane are bent laterally, for example in such a way that they lie on a circular cylinder or segment, instead of this the lateral bend can also be provided in a conical or roof-shaped manner. The hanging can also be spherically or conically curved or, for example, also designed in a plane or polar to the hanging axis or in the circumferential direction corrugated. A similar locking ring can be used to axially secure ropes in bores. In this case, the resilient clamping elements are directed from the closed part not inwards, but outwards.
