Patent attributes
A fastener assembly comprises a first cylindrical member disposed within a second cylindrical member. One is movable relative to the other one in a first direction, and locked in a second direction opposite to the first direction. A spring is operably attached to the members to urge the one in the first direction. The members include opposing first and second cylindrical walls, respectively. A resilient member is disposed between the walls. One of the walls includes a first receiving volume configured to fully receive the resilient member and the other wall a plurality of second receiving volumes configured to only partially receive the resilient member. The resilient member is shifted between the first and second receiving volumes such that the one can move in the first direction but locked in the second direction; and the first and second receiving volumes are configured such that the resilient member is captured within a locking volume formed between the first volume and an opposing second volume when the first and second cylindrical members are locked together, the locking volume having an entrance opening that prevents the resilient member from shifting out of the locking volume and into the first receiving volume.
