Abstract
Abstract A shower stall featuring wall panels joined together to form a three-sided enclosure and a pair of rigid elongated hand rail members attached to opposing ones of the wall panels and extending rearward within the stall to connect to the rear wall panel. An elongated brace is attached to the outside surface of the rear wall panel and extends at least partially across the same to interconnect through the rear wall panel to each of the hand rail members.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
182 words
A shower stall comprising: wall panels joined together to form a three-sided enclosure defining a rear wall, a pair of opposing side walls, a frontal access opening and two right angular rear corners, a pair of rigid elongated hand rail members separate and distinct from one another attached to and extending at least partially along opposing broad surfaces of said side walls within said enclosure, the rear ends of said members extending to and terminating against opposite side portions of said real wall, means for spacing said members from said opposing broad surfaces to permit hand gripping of said members by a person standing within said enclosure, and an elongated brace attached to and extending at least partially across the back of said rear wall outside of said enclosure between the rear ends of said members, opposite end portions of said brace being connected through opposite side portions of said rear wall to different ones of said members, whereby said separate and distinct hand rail members within said enclosure and said brace external to said enclosure interconnect and rigidify said wall panels.
Claim 2
Dependent Claim
182 words
A shower stall comprising: wall panels joined together to form a three-sided enclosure defining a rear wall, a pair of opposing side walls, a frontal access opening and two right angular rear corners, a pair of rigid elongated hand rail members separate and distinct from one another attached to and extending at least partially along opposing broad surfaces of said side walls within said enclosure, the rear ends of said members extending to and terminating against opposite side portions of said real wall, means for spacing said members from said opposing broad surfaces to permit hand gripping of said members by a person standing within said enclosure, and an elongated brace attached to and extending at least partially across the back of said rear wall outside of said enclosure between the rear ends of said members, opposite end portions of said brace being connected through opposite side portions of said rear wall to different ones of said members, whereby said separate and distinct hand rail members within said enclosure and said brace external to said enclosure interconnect and rigidify said wall panels.
Claim 3
Dependent Claim
36 words

Claim 5
Dependent Claim
50 words
The shower stall of claim 1 wherein each of said hand rail members comprises a three sided element, and a pair of flanges centrally disposed in said element and extending longitudinally therethrough, opposing surfaces of said flanges defining longitudinally extending teeth adapted to securely grip the threads of a fastener.
Claim 6
Dependent Claim
11 words
The shower stall of claim 1 further comprising a support frame.
Claim 7
Dependent Claim
24 words
The shower stall of claim 5 wherein said support frame comprises four angle members having mitered ends joined together to form right angular corners.
Claim 8
Dependent Claim
