Rotatable attachment for bathtub faucet safety

A method of configuring a faucet-mounted attachment prior to installation on a faucet, the method comprising:

• placing a projection that is on an interior surface of a first housing portion into a movable configuration relative to the first housing portion using an actuator on the first housing portion;
• actuating a magnetic key to move a locking pin within a second housing portion from a locked position to an unlocked position;
• while the locking pin is in the unlocked position, rotating a first housing portion into engagement with a faucet lever;
• shifting the projection into one of multiple selectable positions that define different permitted ranges of lever rotation in a first plane;
• and
• releasing the actuator to retain the projection in the selected position.

An attachment configured to be removably mounted over at least part of a faucet control lever and at least part of a central portion of a faucet to which the lever is integrally attached, comprising:

• a generally circular first housing portion configured to surround at least part of the central portion of the faucet while providing a clearance that permits partial rotation of the lever in a first plane in a child user mode;
• a connector portion extending from the first housing portion;
• a second housing portion coupled to the connector portion and configured to be affixedly attached to external infrastructure, the first housing portion and the connector portion being rotatable together relative to the second housing portion in a second plane during use of the attachment;
• a projection disposed on an interior surface of the first housing portion and configured to limit rotational movement of the lever in the first plane by physical interference;
• a locking tongue formed on a flexible outer surface of the second housing portion and selectively deflectable between a flexed condition, in which the first housing portion is free to rotate relative to the second housing portion in the second plane, and a straight condition, in which the first housing portion is prevented from rotating relative to the second housing portion in the second plane,
• the locking tongue is securely engaged in a recess of the connector portion,
• wherein deflection of the locking tongue selectively enables rotation of the first housing portion in the second plane, such that rotation of the first housing portion determines whether the projection of the first housing portion is operatively engaged to limit lever rotation in the first plane,
• wherein the projection is fixed in a default position and is movable when released by an actuator situated on the first housing portion in an adult user mode to enlarge a permitted range of lever rotation.
