Locking mechanism for percussion musical instrument

A high hat cymbal has a magnetic clutch that engages the top cymbal and allows it to be controlled by a standard high hat foot pedal. When the drummer's foot is removed from the high hat foot pedal, the magnetic clutch strikes a mechanical arm which causes the magnetic clutch to disengage without any action required on the part of the drummer. The top cymbal can be re-engaged by the magnetic clutch so that the high hat foot pedal can now be operated again, simply by depressing the high hat foot pedal. A trip bar may be provided to provide for automatic disengagement of the clutch mechanism.

Wall-mounted sliding storage enclosure with fail-safe position fixing mechanism

A sliding storage system includes a vertical rod having upper and lower ends. Brackets attach the upper and lower ends of the rod to a wall to fix the rod in a vertical orientation.A storage device in the form of a rigid cabinet slidably is mounted on the rod for free sliding movements between (i) the lower end of the rod for positioning the storage device in a lower position to provide access to a user and allow the user to place an object on or remove an object from the cabinet and (ii) the upper end for positioning the storage device in a storage position generally above the living space of the user. A locking member in the form of a clutch plate cooperates with the cabinet and the vertical rod, the clutch plate being movable between a locking position for locking the cabinet against vertical movements along said rod and a releasing position enabling the cabinet to selectively and freely move vertically upwardly and downwardly along the rod. A spring acting between the cabinet and the clutch plate normally urges the clutch plate to move to the locking position. A manual release is actuatable directly by a user or indirectly by a line extending over a sheave above the rod to move the clutch plate from a locking position to a releasing position when manually actuated by a user to overcome the action of the spring. In this way, manual activation of the manual release allows a user to selectively raise or lower the cabinet to place an object on or remove an object from the cabinet in a lowered position and to store an object in a raised position of the cabinet.
