Abstract
Abstract The invention provides a device for coupling together two elements, each of predetermined shape, so that the two elements are prevented from rotating relative to the device. The device is constituted by a band, which is substantially rigid and is in the form of a closed loop. The band has two rims which are three-dimensionally out of true, and each rim delimiting an opening, which forms the limit of a recess, in which one of the elements to be coupled together can be positioned. The regions of each of the two recesses which lie opposite the openings form part of a single space which is laterally delimited by the band. Each rim substantially constitutes a curve traced on a convex surface of the element of predetermined shape to be coupled. The invention also provides a method of making a coupling device.

A device for coupling together two elongated elements extending at an angle to each other, at least one of which has a convex exterior, so that the two elements are held against relative angular displacement with respect to each other, said device comprising a substantially rigid one piece band comprised of a continuous closed loop of essentially uniform wall thickness, said band having two substantially continuously curving rims, each rim defining an opening which forms the boundary of a recess for receiving a corresponding one of the elements to be coupled together, said boundaries of said recesses defined by said openings defining a single space within and laterally bounded by said band, and each rim substantially constituting a curve traced on a convex surface of the corresponding element to be coupled, at least one rim extending more than 180° around the corresponding element to be coupled.
Claim 2
Independent Claim
146 words
A device for coupling together two elongated elements extending at an angle to each other, at least one of which has a convex exterior, so that the two elements are held against relative angular displacement with respect to each other, said device comprising a substantially rigid one piece band comprised of a continuous closed loop of essentially uniform wall thickness, said band having two substantially continuously curving rims, each rim defining an opening which forms the boundary of a recess for receiving a corresponding one of the elements to be coupled together, said boundaries of said recesses defined by said openings defining a single space within and laterally bounded by said band, and each rim substantially constituting a curve traced on a convex surface of the corresponding element to be coupled, at least one rim extending more than 180° around the corresponding element to be coupled.
