Abstract
A mechanism for releasing friction locks of a telescoping shaft, in which the locks are formed by swaged outer ends of each preceding member of the shaft and flared inner ends of each following member provides a guided axial impact to the end member of the shaft. This mechanism for releasing friction locks in telescoping shafts allows the release of the locks to be more comfortably and accurately accomplished for users than by striking an end of the shaft against a hard surface, such as a concrete wall or pavement.
Claims17
A telescoping shaft having a collapsed configuration and an extended configuration, comprising:
- a plurality of members forming the telescoping shaft, wherein each of the plurality of members are lockable in the extended configuration by a plurality of friction locks;
- a rod configured to be received within an endmost member of the plurality of members, wherein the rod includes an extended position and a retracted position;
- and
- an object attached to a distal end of the rod,
- wherein, when the rod is moved from the extended position to the retracted position with sufficient rapidity, the object strikes the endmost member with sufficient force to unlock the plurality of friction locks.
A telescoping shaft having a collapsed configuration and an extended configuration, comprising:
- a plurality of members forming the telescoping shaft, wherein each of the plurality of members are lockable into the extended configuration by a plurality of respective friction locks;
- a rod configured to be received within an endmost member of the plurality of members, wherein the rod includes a stop at a proximal end and wherein the rod includes an object attached to a distal end of the rod;
- and
- a tension spring between the distal end and the proximal end of the rod,
- wherein, when the rod is moved from a retracted position to an extended position, the stop engages with a portion of the endmost member and the tension spring stretches such that upon release, the rod moves into the endmost member to the retracted position causing the object to strike the endmost member with sufficient force to release the plurality of friction locks.
A telescoping shaft having a collapsed configuration and an extended configuration, comprising:
- a plurality of members forming the telescoping shaft, wherein each of the plurality of members are lockable into the extended configuration by a plurality of friction locks;
- a rod configured to be received within an endmost member of the plurality of members, wherein the rod includes an object attached to a distal end of the rod;
- and
- a compression spring between the distal end and a proximal end of the rod,
- wherein, when the rod is moved from a retracted position to an extended position, the compression spring engages with a portion of the endmost member such that upon release, the rod moves into the endmost member to the retracted position causing the object to strike the endmost member with sufficient force to release the plurality of friction locks.
