Abstract
A reel mount assembly of cylindrical structure includes a cylindrical body having a stationary sleeve mounted on one end and a slidable sleeve mounted on the other end having a male thread over a certain range, and a threaded annular member adapted to mate with the male thread. The slidable sleeve is engaged with the threaded annular member in such a manner that they are rotatable with each other. At the engagement position the annular member is fitted over the slidable sleeve, and vice versa. The outer member has a rigidity sufficient to prevent its expansion, and the inner member is contractive inwardly due to its resiliency.
Claims3
In a reel mount assembly of cylindrical structure comprising a cylindrical body having a male thread over a predetermined range, a stationary sleeve mounted on one end and a slidable sleeve member slidingly mounted on the other end, a threaded annular member adapted to mate with said male thread, said slidable sleeve member and said annular member being rotatably coupled to each other in a male-female manner, said slidable sleeve member being slid by turning said annular member, the improvement comprising both said slidable sleeve member and said threaded annular member being formed of a plastic material, and a metal ring being fitted over the outermost of said members where said members overlap to provide a rigidity sufficient to prevent its outward expansion and the other of said members being resiliently fitted into said outermost member, whereby accidental disconnection of said members is prevented.
