Abstract

Abstract A deformable or destructable coupling designed to function as a shock absorbing device under overload conditions to relieve and/or progressively reduce forces applied to cables, tow lines, and other members which are relatively movable in a longitudinal direction upon the application of tension or compression thereto. The invention is particularly adapted for use with highway signs, utility poles, guard rails and the like which may be released or broken at the base by impact such as a collision while still being connected to or partially supported by lines or connections extending to other posts or supports.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 100 words
An assembly embodying two horizontally spaced, vertically extending supports with a member extending therebetween and a shock absorber connected to said assembly to reduce the forces exerted upon said member upon relative movement of one of said supports with respect to said member, said shock absorber including two interengaging elements one of which is connected to said one of said supports and the other of which is connected to and movable by another member of said assembly, said interengaging elements being relatively movable and one of said elements being deformable by the other of said elements upon such relative movement.
Claim 2
Dependent Claim 100 words
An assembly embodying two horizontally spaced, vertically extending supports with a member extending therebetween and a shock absorber connected to said assembly to reduce the forces exerted upon said member upon relative movement of one of said supports with respect to said member, said shock absorber including two interengaging elements one of which is connected to said one of said supports and the other of which is connected to and movable by another member of said assembly, said interengaging elements being relatively movable and one of said elements being deformable by the other of said elements upon such relative movement.
Claim 3
Dependent Claim 45 words
An assembly as defined in claim 1 wherein one of said elements is tubular in shape and the other of said element is in the form of a pin extending radially with respect to said tubular element and into an opening in said tubular element.
Claim 4
Dependent Claim 99 words
An assembly including two horizontally spaced, vertically extending posts with a member connected to the upper portion of both posts, one of said posts being mounted on a support by means which are destructable upon impact of an object with said post, and shock absorbing means movable with the latter post upon destruction of said mounting means, said shock absorbing means including two interengaging elements one of which is deformable by the other upon relative movement thereof, and one of which elements is connected to said latter post, and the other of which elements is connected to said member.
Claim 5
Dependent Claim 99 words
An assembly including two horizontally spaced, vertically extending posts with a member connected to the upper portion of both posts, one of said posts being mounted on a support by means which are destructable upon impact of an object with said post, and shock absorbing means movable with the latter post upon destruction of said mounting means, said shock absorbing means including two interengaging elements one of which is deformable by the other upon relative movement thereof, and one of which elements is connected to said latter post, and the other of which elements is connected to said member.
Claim 6
Dependent Claim 63 words
The combination as defined in claim 3 wherein one of said elements is tubular in form and is movable with said one of said posts upon displacement thereof with respect to said support, and the other of said elements is in the form of a pin extending into an opening in the tubular element and is connected to said member by a cable.
