ABSTRACT:
A tamper resistant faucet handle is provided for locking conventional sink or bath faucets in a closed or partially closed position. The tamper resistant faucet handle includes a handle body mounted to the flow control lever and a movable interference plunger that is slidably located within a plunger bore contained in the handle body. A locking mechanism locks the interference plunger in either an inward position or an outward position. When the interference plunger is locked in the outward position, it resides partially beyond the surface of the handle body for a distance sufficient for the plunger to interfere with movement of the handle body and consequently the flow control lever. In this manner, the locked plunger limits the range of movement of the flow control lever to lock the faucet in a closed or semi-closed position. The locking mechanism can be released and the plunger returned to the inward position, thus re-establishing a full range of movement for the handle and the flow control lever. An embodiment of the invention is disclosed for use on single control faucets, and another embodiment is disclosed for use on dual control faucets. The locking mechanism requires two-handed coordination, and is therefore childproof. The locking mechanism for both embodiments preferably includes an actuation button that can be removed to prevent unauthorized use of the faucet by children or adults.
