ABSTRACT:
A hairbrush is disclosed having an elongated, generally hollowed handle having a receiving cavity and a separate brush head having a connection end. At the inside base of the receiving cavity is a first blade slot for retaining one end of a flat, elongated spring blade. The connection end of the brush head has a second blade slot for retaining the other end of the flat, elongated spring blade. A locking button retained slidably within a button slot which penetrates the handle engages into a slotted collar in which a locking slot is formed on the connection end of the brush head by a pair of rotation locking tabs. The impingement of the rotation locking tabs against the locking button thereby prevents rotational motion of the brush head relative to the handle. Finally, in order to prevent the brush head from fully rotating completely about the handle and thereby causing damage or breakage to the blade spring or other parts, a rotation limiting means is provided in its preferred embodiment as a rotation limiting pin protruding slightly into the receiving cavity and aligned with the brush head connection end at a point in close proximity to the slotted collar. When the brush head is rotated relative to the handle the impingement of the rotation locking tabs against the rotation limiting pin thereby prevents complete rotation of the brush head, and provides a limited range of rotatable motion in either direction.
