20110133050 | Adjustable Mounting Assemblies with Locking Systems - A locking system for use in adjusting a mounting assembly includes a lock plate and a lock shaft mount. A lock shaft component is rotatably received within an opening of the lock of the lock plate and rotatably supported by the lock shaft mount. With the locking system in a locked configuration, the lock shaft component engages the lock plate which locks the positions of the lock plate relative to the position of the lock shaft mount. With the locking system in an unlocked configuration, the lock shaft component disengages the lock plate such that the lock plate moves along a length of the lock shaft component toward and away from the lock shaft mount. | 06-09-2011 |
