Abstract

Abstract This method of covering a joint of two rope ends includes use of a joint cover constructed of plastic tubing, included heat shrinkable plastic tubing, with methods to form a conical wedge shaped cover. The joint cover functions to help provide a smooth movement of the joint around obstacles. Also included is the use of "selected area shrinkage."

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 267 words
A cover means for enclosing a joint area of two rope ends to facilitate smoother movement around an obstacle than if the joint area was uncovered, said cover means being comprised of: (a) at least one cover sleeve of heat shrinkable tubing covering the joint and adjacent joint area, said tubing extending on at least one side of said joint, and (b) at least one smaller diameter support tube of heat shrinkable tubing covering said adjacent joint area, and telescoping within said cover tube, with the length of said support tube sufficiently long to extend beyond the outer end of said cover tube for the purpose of forming additional transitional conical wedge shape to facilitate smoother movement around said obstacle, and (c) said heat shrinkable tubing being fully shrunk only on the ends away from said joint, thereby reducing clearance between said rope and said tubings for the purpose of forming additional transitional conical wedge shape to facilitate smoother movement around said obstacle, and (d) said heat shrinkable tubing being partially shrunk in the area adjacent said joint, and unshrunk in the portion covering the actual joint, with the partially shrunk area being between the unshrunk and shrunk area, for the purpose of forming additional conical wedge shape to facilitate smoother movement around said obstacle, with the length relationships of the tubing sections being: for the unshrunk portion of the cover sleeve approximately twice the joint length; for the partially shunk area of the cover sleeve and support sleeve approximately one-half the joint length, and the fully shrunk portion being the remaining length of the tubing sections.
Claim 2
Dependent Claim 267 words
A cover means for enclosing a joint area of two rope ends to facilitate smoother movement around an obstacle than if the joint area was uncovered, said cover means being comprised of: (a) at least one cover sleeve of heat shrinkable tubing covering the joint and adjacent joint area, said tubing extending on at least one side of said joint, and (b) at least one smaller diameter support tube of heat shrinkable tubing covering said adjacent joint area, and telescoping within said cover tube, with the length of said support tube sufficiently long to extend beyond the outer end of said cover tube for the purpose of forming additional transitional conical wedge shape to facilitate smoother movement around said obstacle, and (c) said heat shrinkable tubing being fully shrunk only on the ends away from said joint, thereby reducing clearance between said rope and said tubings for the purpose of forming additional transitional conical wedge shape to facilitate smoother movement around said obstacle, and (d) said heat shrinkable tubing being partially shrunk in the area adjacent said joint, and unshrunk in the portion covering the actual joint, with the partially shrunk area being between the unshrunk and shrunk area, for the purpose of forming additional conical wedge shape to facilitate smoother movement around said obstacle, with the length relationships of the tubing sections being: for the unshrunk portion of the cover sleeve approximately twice the joint length; for the partially shunk area of the cover sleeve and support sleeve approximately one-half the joint length, and the fully shrunk portion being the remaining length of the tubing sections.
