Abstract
A spring loaded actuator assembly includes a first member having a set of rails, a second member configured to translate axially relative to the first member and a third member configured for translational movement within the second tubular member. The second and third members each include a set of ramp-like teeth configured to engage one another when the third member is moved within the second member; and grooves configured to engage the rails of the first member and permit translational movement of the second and third members relative to the first member while preventing rotational movement of the second and third members. A coil spring is disposed between the first and second members wherein translational movement of the second member beyond a predetermined axial position causes the ramp-like teeth of the second member to extend beyond the rails, causing the second member to rotate and the ramp-like teeth to be retained by the rails of the first member, thereby maintaining the coil spring in a compressed condition while enabling the third member to be freely movable axially.
