Linearly Adjustable Device
First Claim
1. A linearly adjustable device, the device comprising:
- a main body including at least two body sections each having a longitudinal axis, said sections being operatively connected together for linear movement relative to one another in the axial direction;
a linear actuator operatively mounted to the main body for causing the relative axial movement between the body sections, the linear actuator including a drive and a power transmission mechanism operatively connected to the drive, the transmission mechanism including an elongated threaded member operatively connected to one of the body sections and a cooperating threaded member operatively connected to another of the body sections such that relative rotation between the elongated threaded member and the cooperating threaded member causes relative movement of the body sections; and
a coupling ring releasably coupled to one of the body sections, the coupling ring including one or more biased members which cooperate with a slot provided in the other body section for restricting relative rotation therebetween.

Abstract
A linearly adjustable device comprising a main body including at least two body sections each having a longitudinal axis, and a linear actuator. The sections are operatively connected together for linear movement relative to one another in the axial direction. The linear actuator is operatively mounted to the main body for causing the relative axial movement between the body section. The linear actuator includes a drive and a power transmission mechanism operatively connected to the drive. The transmission mechanism includes an elongated threaded member operatively connected to one of the body sections and a cooperating threaded member operatively connected to another of the body sections such that relative rotation between the elongated threaded member and the cooperating threaded member causes relative movement of the body sections,
