Any suitable mechanical engaging structure rotatable or drivable by a suitable tool may be employed as the engaging structure in accordance with the present disclosure.
[0047] The central portion 1196 of the attachment member 1172 is a solid cylindrical member (not labeled) and includes an outer surface (not labeled). The outer surface has a second outer diameter. The second outer diameter is smaller than the first outer diameter of the head 1192. The second outer diameter is also smaller than the second inner diameter of the central portion 1186 of the gripping member 1174 such that the center portion 1196 is rotatable in the gripping member 1174 during installation and removal.
[0048] The inner portion 1200 of the attachment member 1172 is also a solid cylindrical member (not labeled) and includes a threaded outer surface (not labeled). The outer surface has a third outer diameter. The third outer diameter is smaller than the first outer diameter of the head 1192 and slightly larger than the second outer diameter.
[0049] The inner portion 1200 is rotatable in the central portion and the inner portion of the gripping member 1174 during installation and removal. The inner portion and specifically the threads of the inner portion are configured to engage the threads of the locking pin 160 that define opening 164 to form a secure engagement with the locking pin 160.
[0050] This configuration enables the gripping member 1174 to be freely rotatable relative to the attachment member 1172 and the locking pin 160 during installation and removal. In this illustrated embodiment, after installation, the gripping member 1174 is fixed to the locking pin 160 by the attachment member 1172 and the locking member 1175 such that the gripping member 1174 is not freely rotatable. It should be appreciated that the locking member 1175 assists in facilitating this locked secure connection of the attachment member 1172 and the gripping member 1174 to the locking pin 160. It should also be appreciated that other suitable or additional suitable locking mechanisms may be employed in accordance with the present disclosure. For example, a liquid locking mechanism may also be applied to the threads of the attachment member 1172 to secure the attachment member to the locking ping 160.
[0051] It should further be appreciated that in other embodiments of the present disclosure, these components can be configured such that the gripping member is freely rotatable relative to the locking pin 160.
[0052] This configuration also enables the attachment member 1172 to be substantially protected by the gripping member 1174 from damage by objects.
[0053] The configuration also enables the conical inner portion 1190 of the gripping member 1174 to engage the wall of the tubular member 140 that defines opening 146 without causing substantial damage or wear to either such component.
[0054] It should be appreciated that the handle assembly may be alternatively configured and shaped in accordance with the present disclosure.
