ABSTRACT:
Embodiments of the present invention are directed to a dynamic apparatus for locking or stabilizing an input device such as a foot-operated device with respect to the floor. In one embodiment, an input device with a non-permanent floor mount comprises a user manipulable object movably coupled to a body of the input device which is configured to be placed on a floor. The user manipulable object is movable by a user applying a force thereon having a force component in a forward direction along the floor. A floor lock is movably connected to the body of the input device and has a contact surface for engaging the floor to substantially prevent movement of the input device in the forward direction along the floor. The floor lock is configured to move with respect to the body of the input device in a downward direction toward the floor and a rearward direction opposite from the forward direction in response to the force applied by the user on the user manipulable object having the force component in the forward direction along the floor.
