Abstract
Abstract The instant invention is comprised of a rope having a tensioncushioning shock absorber whereby the rope is passed through oppositely arranged openings in a rubber element which has high extensibility and resilience, said rope being firmly fixed to opposite points of said rubber element by means of clamps and abutments whereby the length of the rope section situated between the abutments is loosely wound when unloaded or lightly loaded and the axial length of said rope section corresponds to the maximum extended dimension of the rubber element whereby said loosely wound rope section is completely stretched out when under full tension load so that any initial shock is absorbed by the rubber element and the maximum tensile stress is absorbed by the rope.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
127 words
A rope having a tension-cushioning shock absorber, comprising: a rubber element having high extensibility as well as resilience, the cross section of which is as thick or thicker than its width; a rope passing through oppositely arranged holes in said rubber element, said rope being secured to opposite ends of said rubber element by a plurality of clamp means and a plurality of abutment means in a manner whereby the length of the rope section situated between said abutment means corresponds to slightly less than the maximum extensibility of said rubber element so that said rope section is in loosely wound form when said rubber element is in normal or lightly loaded position whereby said rope section is completely stretched out when under a full tension load.
Claim 2
Dependent Claim
127 words
A rope having a tension-cushioning shock absorber, comprising: a rubber element having high extensibility as well as resilience, the cross section of which is as thick or thicker than its width; a rope passing through oppositely arranged holes in said rubber element, said rope being secured to opposite ends of said rubber element by a plurality of clamp means and a plurality of abutment means in a manner whereby the length of the rope section situated between said abutment means corresponds to slightly less than the maximum extensibility of said rubber element so that said rope section is in loosely wound form when said rubber element is in normal or lightly loaded position whereby said rope section is completely stretched out when under a full tension load.
Claim 3
Dependent Claim
34 words
A rope having a tension-cushioning shock absorber, as described in claim 1, wherein the rubber element consists of a rubber ring the cross section of which is as wide or wider transversely than radially.
Claim 4
Dependent Claim
45 words
A rope having a tension-cushioning shock absorber as described in claim 2 wherein the abutment means are comprised of a holding device having tube extensions which are inserted into the holes in said rubber element, said holding devices being flared on their sides and edges.
Claim 5
Dependent Claim
24 words
A rope having a tension-cushioning shock absorber as described in claim 3 wherein the edges are flared in a direction opposite the side flares.
Claim 6
Dependent Claim
37 words
A rope having a tension-cushioning shock absorber as described in claim 2 wherein the rope clamp is provided with a clamp shoulder which bears against the holding device when the rope is inserted in the abutment cutout.
Claim 7
Dependent Claim
34 words
A rope having a tension-cushioning shock absorber as described in claim 3 wherein the rope clamp has a radius which bears against the holding device when the rope is inserted in the abutment cutout.
Claim 8
Dependent Claim
22 words
A rope having a tension-cushioning shock absorber as described in claim 2 wherein the abutment is comprised of a flat steel plate.
Claim 9
Dependent Claim
26 words
A rope having a tension-cushioning shock absorber as described in claim 1 wherein the rubber element is comprised of the bar portion of a dumb-bell configuration.
Claim 10
Dependent Claim
19 words
A rope having a tension-cushioning shock absorber as described in claim 7 wherein the abutment consists of a washer.
Claim 11
Dependent Claim
41 words
A rope having a tension-cushioning shock absorber as described in claim 8 whereas the bar portion of the dumb-bell has an enlarged center and holes are provided in the end bulges and the enlarged center through which the rope is passed.
Claim 12
Dependent Claim
19 words
A rope having a tension-cushioning shock absorber as described in claim 1, wherein the rope is comprised of steel.
Claim 13
Dependent Claim
49 words
A ropE having a tension-cushioning shock absorber as described in claim 1, wherein the rubber element is comprised of a plurality of flexible rubber rings which pass through an opening of a holding device wherein said holding device acts as a guide as well as abutment for the rope.
Claim 14
Dependent Claim
17 words
A rope having a tension-cushioning shock absorber as described in claim 12 wherein the rope is non-metallic.
Claim 15
Dependent Claim
