Abstract
A locking mechanism for controlling the retraction and extraction of a tape or other like device. The mechanism includes a housing having a tape opening and a locking mechanism opening. A tape blade extends through the housing tape opening and has a distal end and a proximal end. The tape blade is selectively positionable between a retracted position wherein the distal end is positioned against the housing and an extended position in which the distal end is positioned distant from the housing. A tape biasing device is operatively connected to the tape blade proximal end for urging the tape blade towards the retracted position. A locking mechanism is rotatably mounted within the housing about a plane substantially orthogonal to the tape blade. The locking mechanism has an actuator extending through the locking mechanism openings and a head. The locking mechanism is selectively rotatable between a disengaged orientation in which the head is positioned away from the tape blade, and an engaged orientation in which the head contacts the tape blade.
