Patent ID: 7896570

Claim:
A retention clamp system, comprising: an assembly including: a shaft having a stop member, a drive member portion and a first threaded portion, the first threaded portion including a left hand thread; a clamping member having a body with a hook extending from the body, the hook having a tapered engagement face, the body having internal left hand threads threadably connected to the first threaded portion, the tapered engagement face angled with respect to a longitudinal axis of the shaft and facing away from the drive member portion of the shaft; and a biasing member positioned between and in frictional contact with both the stop member and the clamping member operating by the frictional contact to transfer a rotational force applied to the shaft to the clamping member to rotate the clamping member into an engagement position; an enclosure member having a peripheral wall to which the shaft is rotatably connected, the peripheral wall defining an enclosure cavity and a clamp cavity which receives the assembly; and a device received in the enclosure cavity of the enclosure member and releasably retained by the clamping member by operation of the assembly, the device having: an internal body cavity, the hook of the clamping member initially positioned in the clamp cavity of the enclosure member, the clamping member rotatable by rotation of the shaft transferring the rotational force to the clamping member through the biasing member to rotate the hook from the clamp cavity into the body cavity of the device; and an engagement wall created in the body cavity contacted by the tapered engagement face of the clamping member after the hook is rotated into the body cavity by a clockwise rotation of the shaft moving the clamping member away from the drive member portion to engage the tapered engagement face with an engagement face of the engagement wall to establish the engagement position, and releasably retain the device within the enclosure member, wherein an opposite rotation of the shaft releases the hook from the engagement face of the engagement wall.
