ABSTRACT:
A plastic injection molded adjustable arm assembly includes a base (102) having a detent wheel (104) that includes a plurality of detents (e.g., 106). An adjustable arm (202) includes a snap-in (204) for rotatably attaching the arm to the base. The arm also includes a locking mechanism (214) that includes a lever (218) that is attached to the arm at a fulcrum (216). A pawl (220) is located at one end of the lever (218a) to engage one of the detents in the detent wheel, thereby locking the arm in one of several angular positions. To release the lock and move the arm to a different position, the user pushes on the end of the lever opposite the pawl (218b), thereby causing the pawl to disengage from the detent. The base and the arm are each injection moldable using a single action mold. In one embodiment, the arm can be moved in one direction by the application of direct pressure to the arm, but it cannot be moved in the opposite direction until the locking lever is manually released. In a second embodiment, the arm cannot be moved in either direction until the locking lever is released manually.
