Abstract: A locking structure for two telescoping tubular members is provided with an outer tube member and an inner tube member slidable inside the outer tube member. An expansion member is located within the outer tube member. The expansion member contains at least two tapered members each having innermost and outermost portions, the outermost portions being spaced no more than 1/2 inch from each other. On the expansion member is an outer tube pressure member shaped to fit the expansion to member and disposed between said the expansion member and the inner surface of the outer tube member. The expansion member may be attached to the inner tube member. The expansion member is moved in opposite directions inside the outer tube member so that when said expansion member is moved in a first direction, pressure is directly applied to the outer tube pressure member which in turn applies pressure to the inner surface of the outer tube member thereby maintaining the inner and outer tube members in a locked position.
Abstract: An improved ski pole is provided containing an easily removable hand grip. The grip contains an inner sleeve, an outer covering over the inner sleeve and hand operational pressure means for tightening and loosening the inner sleeve on the shaft of the ski pole.
