Abstract: A three point clamping means is employed to secure one end of a shower bench to the edge of a bathtub. The bench includes two vertical feet which sit inside the bathtub, a pair of rails connected to said vertical feet and a clamping section. A chair unit is attachable to the rails and can be conveniently locked in position with respect thereto. A pair of C-shaped legs extend beyond the bathtub and make contact with the outside edge of said bathtub at two points. One point clamping contact is made on the inside of the bathtub by a single depending foot which includes a resilient pad mounted thereon. The depending foot is carried on a cross-brace slidably supported by said two rails and driven by a threaded crank mechanism. Rotation of the crank squeezes the bathtub edge at three points, namely, by the movable depending foot on the inside and by the two stationary C-shaped leg means on the outside. The improved clamping means is very easy to use and extremely secure compared to prior art clamping devices.

Abstract: A shower bench apparatus includes a positively engagable non-tipping chair and an easily operable clamping mechanism for attaching the apparatus to the side of a bathtub. The seat of the chair includes a pair of front hook-like brackets for engaging a first rail of the bench and a pair of craddle-like brackets near the rear of said seat for engaging the second rail of the bench. Locking screws are used to positively attach the rear craddling brackets to the second rail. It is virtually impossible to tip the chair over backwards due to the positive engagement of the front hook brackets. The chair may be reversed 180.degree. and repositioned with a minimum of effort. The device is readily clampable to the edge of a bathtub by means of a clamping mechanism driven by a single, easily manipulatable knob.
