Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 69 words
A shower surround for a tub or shower base having a rim surface, comprising a substantially flat back panel having vertical edges spring-tensioned outwardly, side panels having one vertical edge engageable with the vertical spring-tensioned side edges of said back panel, to form a shower surround having a backwall and two adjoining sidewalls which are supported against movement relative to each other by means of said spring-tensioned side edges.
Claim 2
Dependent Claim 69 words
A shower surround for a tub or shower base having a rim surface, comprising a substantially flat back panel having vertical edges spring-tensioned outwardly, side panels having one vertical edge engageable with the vertical spring-tensioned side edges of said back panel, to form a shower surround having a backwall and two adjoining sidewalls which are supported against movement relative to each other by means of said spring-tensioned side edges.
Claim 3
Dependent Claim 47 words
A shower surround having the features provided for in claim 1, wherein an adhesive-receiving furrow is formed along and adjacent the vertically extending edges of each back panel, the furrows being opposed to the sidewalls to form a watertight seal therewith when the shower enclosure is assembled.
Claim 4
Dependent Claim 91 words
A shower surround as provided for in claim 1, made from fiber glass wherein an inwardly extending foot is formed along the bottom edge of each panel, said foot being resilient and flexible to permit the bottom edge of the panel to deflect into contact with the rim surface of said tub or shower base to form a watertight joint between the tub and shower, and means for supporting the panels against upward movement relative to the tub after the extending feet have been pushed downwardly into contact with the tub.
Claim 5
Dependent Claim 70 words
A shower surround for a bathtub as provided for in claim 1, wherein the upper horizontal edges of the side ends of the shower surround are provided with a nailing flange, having a separate abutment formed thereon against which wall-covering material is placed and a separate paint abutment formed therein having paint masking tape positioned adjacent thereto when installed to facilitate painting the wall surfaces overlapping the horizontal nailing flange.
Claim 6
Dependent Claim 48 words
A shower surround having the features provided for in claim 1, wherein enlarged columns are formed at the outer vertical edges of the shower-surround end walls, the outermost edge terminating in a nailing tab for securing the outer edge of the surround to the walls of the bathroom.
Claim 7
Dependent Claim 39 words
A shower surround for a tub, having the features provided for in claim 1, a waterproof sealant is placed between spring-tensioned edges of the back panel and the sidewalls adjoining the backwall to make a water and shearproof joint.
Claim 8
Dependent Claim 46 words
A shower surround having the features provided for in claim 3, wherein the spring-tensioned edges of the sidewall acts as a latch and the edge of the sidewalls engaging therewith has formed therein latch-receiving indentations to form a locked joint between the end and sidewall panels.
Claim 9
Dependent Claim 123 words
A shower surround for a conventional bathtub, comprising a back side shower panel having side edges spring tensioned outwardly, end panels having inwardly spring-tensioned means formed along one edge of each end panel adjacent the vertically extending spring-tensioned side edges of said back panel to interlock with the side edges of said back side panel to form a shower enclosure conforming to the external configuration of the tub, a spring-tensioned foot flange formed at and along the bottom of said back and side panels and positioned to contact and conform with the surfaces of the tub rim when downward pressure is exerted on said back and side panels and means for maintaining said panels Against vertical movement while holding said feet under tension.
Claim 10
Dependent Claim 123 words
A shower surround for a conventional bathtub, comprising a back side shower panel having side edges spring tensioned outwardly, end panels having inwardly spring-tensioned means formed along one edge of each end panel adjacent the vertically extending spring-tensioned side edges of said back panel to interlock with the side edges of said back side panel to form a shower enclosure conforming to the external configuration of the tub, a spring-tensioned foot flange formed at and along the bottom of said back and side panels and positioned to contact and conform with the surfaces of the tub rim when downward pressure is exerted on said back and side panels and means for maintaining said panels Against vertical movement while holding said feet under tension.
