Abstract:
1. A telescoping tube position lock apparatus comprising: a first tube at least partially nested in a second tube; an inner wedge base established substantially at an end of said first tube; and a friction wedge that is established so that a concave side thereof faces said first tube, said friction wedge reconfigurable from a pressure wedge configuration when said apparatus is in a tube lock mode to a release configuration when said apparatus is in a relative tube position adjustment mode; a manual controller to which said friction wedge is positionally responsive, said manual controller manually operable to apply a release force so as to reconfigure said apparatus from said tube lock mode to said relative tube position adjustment mode; a biaser that applies a bias force that is opposite said release force and that urges said friction wedge against said inner wedge base so as to pressurize at least a portion of said friction wedge between said inner wedge base and an interior surface of said second tube to effect said pressure wedge configuration, thereby urging said apparatus towards said tube lock mode; and a user activatable rod that passes through at least a portion of said first tube, wherein said biaser biases said user activatable rod towards an inner wedge base distal portion of said first tube.
