Abstract
A locking system for a cart having at least one drawer movable between an open position and a closed position. The locking system includes a cam that is movable between a locked position, wherein the drawer of the cart is prevented from moving between the closed and open positions, and an unlocked position, wherein the drawer is released for movement between the closed and open positions. A manually actuated lock mechanism is coupled to the cam and is operable to move the cam between the locked and unlocked positions. An electronically actuated lock mechanism cooperates with the manually actuated lock mechanism to permit automatic operation of the locking system.
Claims15
A locking system for a cart having at least one drawer movable between an open position and a closed position, the locking system comprising:
- a cam operatively coupled to the drawer and having an unlocked position wherein the drawer is movable between the open position and the closed position, and having a locked position wherein the drawer is not moveable from the closed position;
- a manually actuated lock mechanism operable to permit manual manipulation of said cam between said locked position and said unlocked position;
- and
- an electronically actuated lock mechanism cooperating with said manually actuated lock mechanism to automatically move said cam between said locked position and said unlocked position;
- wherein said manually actuated lock mechanism comprises:
- a lock core coupled to said cam and configured for manual manipulation between a first position corresponding to said locked position of said cam, and a second position corresponding to said unlocked position of said cam, and
- a lock catch having an engaged condition wherein said lock core is secured against movement from said first position to said second position, and a disengaged condition wherein said lock core is moveable between said first position and said second position.
A locking system for a cart having at least one drawer moveable between an open position and a closed position, the locking system comprising:
- a cam operatively coupled to the drawer and having an unlocked position wherein the drawer is movable between the open position and the closed position, and having a locked position wherein the drawer is not moveable from the closed position;
- a manually actuated lock mechanism operable to permit manual manipulation of said cam, selectively, from said locked position toward said unlocked position, and from said unlocked position toward said locked position;
- and
- an electronically actuated lock mechanism cooperating with said manually actuated lock mechanism to automatically move said cam selectively from said locked position toward said unlocked position, and from said unlocked position toward said locked position.
A lockable cart, comprising:
- a cart chassis;
- at least one drawer supported on said cart chassis and moveable between an open position and a closed position;
- a cam operatively coupled to said drawer and having an unlocked position wherein said drawer is movable between said closed position and said open position, and having a locked position wherein said drawer is not movable from said closed position;
- a manually actuated lock mechanism operable to permit manual manipulation of said cam between said locked position and said unlocked position;
- and
- an electronically actuated lock mechanism cooperating with said manually actuated lock mechanism to automatically move said cam between said locked position and said unlocked position, and to automatically move said cam between said unlocked position and said locked position.
A method of operating a lockable drawer of a cart, wherein the drawer is movable between an open position and a closed position, the method comprising:
- selectively operating a manually actuated lock mechanism coupled to the drawer and movable between a locked condition wherein the drawer is prevented from being moved from the closed position to the open position, and an unlocked condition wherein the drawer is released for movement between the closed position and the open position, and
- selectively operating an electronically actuated lock mechanism coupled to the drawer and cooperating with the manually actuated lock mechanism to automatically move the manually actuated lock mechanism between the locked condition and the unlocked condition, and to automatically move the manually actuated lock mechanism between the unlocked condition and the locked condition.
