Abstract
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° 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
145 words
In a shower bench apparatus, including a bench having at least two feet and a first and a second rail attached to said feed and a chair unit attachable to said rails, the improvement comprising: stationary hook bracket means rigidly attached to the underside of said chair unit for selective engagement with one of said bench rails; stationary cradling bracket means rigidly attached to the underside of said chair unit for selective engagement with the other bench rail; and, locking means attached to said cradling bracket means for selectively locking said chair unit with respect to at least one of said rails, said locking means comprising a threaded means locatable below the center of said rail when said chair unit is engaged with said rail for selectively occupying space in said cradling bracket means thereby preventing said rail from escaping from said cradling bracket means.
Claim 2
Dependent Claim
145 words
In a shower bench apparatus, including a bench having at least two feet and a first and a second rail attached to said feed and a chair unit attachable to said rails, the improvement comprising: stationary hook bracket means rigidly attached to the underside of said chair unit for selective engagement with one of said bench rails; stationary cradling bracket means rigidly attached to the underside of said chair unit for selective engagement with the other bench rail; and, locking means attached to said cradling bracket means for selectively locking said chair unit with respect to at least one of said rails, said locking means comprising a threaded means locatable below the center of said rail when said chair unit is engaged with said rail for selectively occupying space in said cradling bracket means thereby preventing said rail from escaping from said cradling bracket means.
Claim 3
Dependent Claim
29 words
The bench apparatus of claim 1 wherein said chair unit comprises: a chair frame; a seat means attached to said frame; and, a back means attached to said frame.
Claim 4
Dependent Claim
41 words
The bench apparatus of claim 2 wherein said hook bracket means is attached to the underside of said seat means and near the front edge thereof and said cradling bracket means is attached to the rear portion of said seat means.
Claim 5
Dependent Claim
17 words
The bench apparatus of claim 3 wherein said hook bracket means comprise at least two hook-like brackets.
Claim 6
Dependent Claim
18 words
The bench apparatus of claim 4 wherein said cradling bracket means comprise at least two cradle-like U-shaped brackets.
Claim 7
Dependent Claim
28 words
The bench apparatus of claim 5 further including: guide means attached to said rail means for positioning said hook-like brackets and said chair unit relative to said rails.
Claim 8
Dependent Claim
155 words
In a shower bench apparatus for use in a bathtub said apparatus including a bench having at least two feet and a first and a second rail attached to said feed and a chair unit attachable to said rails, the improvement comprising: a slidable section including a cross-brace means for sliding on said first and second rails; sleeve means attached to said cross-brace means and surrounding said rails; depending means attached to said cross-brace means; resilient means attached to said depending means for engagement with the inside wall of said bathtub; hand operable means connected to said slidable section for driving said slidable section along said rails; and, a stationary section forming a part of said bench which normally lies outside of said bathtub, wherein manipulation of said hand-operable means urges said slidable section towards and away from said stationary section thereby clamping and unclamping said bench with respect to the edge of said bathtub.
Claim 9
Dependent Claim
155 words
In a shower bench apparatus for use in a bathtub said apparatus including a bench having at least two feet and a first and a second rail attached to said feed and a chair unit attachable to said rails, the improvement comprising: a slidable section including a cross-brace means for sliding on said first and second rails; sleeve means attached to said cross-brace means and surrounding said rails; depending means attached to said cross-brace means; resilient means attached to said depending means for engagement with the inside wall of said bathtub; hand operable means connected to said slidable section for driving said slidable section along said rails; and, a stationary section forming a part of said bench which normally lies outside of said bathtub, wherein manipulation of said hand-operable means urges said slidable section towards and away from said stationary section thereby clamping and unclamping said bench with respect to the edge of said bathtub.
Claim 10
Dependent Claim
49 words
The shower bench apparatus of claim 7 wherein said hand-operable means includes: a handle means; a threaded means attached to said handle means; a bracket means attached to said stationary section for supporting said threaded means; and, a following means for attaching said threaded means to said cross-brace means.
Claim 11
Dependent Claim
32 words
The shower bench apparatus of claim 8 wherein said threaded means is attached to said cross-brace means by a Nylon® plug means loosely connected to said cross-brace means in a housing means.
Claim 12
Dependent Claim
45 words
The shower bench apparatus of claim 9 wherein said stationary section comprises: a "C"-shaped leg means attached to said rails and locatable outside of said bathtub; and, rubber feet means connected to said "C"-shaped leg means for engagement with the outside wall of said bathtub.
Claim 13
Dependent Claim
72 words
The shower bench apparatus of claim 10 wherein said rubber feet means attached to said "C"-shaped leg means and locatable on the outside of said bathtub are located approximately 2" below said resilient means connected to said slidable section and locatable on the inside of said bathtub, whereby the clamping of said appartus causes said shower bench apparatus to rotate and put pressure down on the two feet of said shower bench.
Claim 14
Dependent Claim
15 words
The shower bench apparatus of claim 11 wherein said two feet are adjustable in length.
Claim 15
Dependent Claim
14 words
