Abstract
Abstract An improved molded bathtub fixture adapted to be manufactured as a single piece to allow separation into two integral elements for installation and handling is disclosed. The subject bathtub fixture, including a bathtub and three upwardly extending contiguous walls is characterized by having a lateral bulge which extends for the length of the walls and which serves to permit the molded bathtub fixture to be separated into two separate pieces at a construction site to facilitate handling and installation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
The method for forming a molded bathtub and associated wall extending above the bathtub, comprising: molding a plastics bathtub with an integral wall extending above a rim of the tub and forming in said wall an outwardly extending bulge having three connected wall portions along a length of the wall; severing said wall along its length in the vicinity of the bulge to form mating upper and lower flanges, from said wall portions, which can be interfitted together to form said bathtub with said associated wall extending above the bathtub.
Claim 2
Independent Claim
90 words
The method for forming a molded bathtub and associated wall extending above the bathtub, comprising: molding a plastics bathtub with an integral wall extending above a rim of the tub and forming in said wall an outwardly extending bulge having three connected wall portions along a length of the wall; severing said wall along its length in the vicinity of the bulge to form mating upper and lower flanges, from said wall portions, which can be interfitted together to form said bathtub with said associated wall extending above the bathtub.
Claim 3
Dependent Claim
88 words
The method defined by claim 1, said step of molding including the steps of: placing a raised strip on a portion of a mold used to form said bathtub fixture, said portion corresponding to the location of said wall section on which said bulge is formed; covering said raised strip and said mold with solidifable material with which said bathtub fixture is being formed; solidifying said material; and separating said material when solidified from said mold and said raised strip, whereby said solidified material is a bathtub fixture.
Claim 4
Dependent Claim
44 words
The method defined by claim 2, said step of placing including the steps of: shaping a raised strip to have a uniform cross-sectional configuration conforming to a corresponding configuration desired for said bulge; and securing said raised strip to the surface of said mold.
Claim 5
Dependent Claim
108 words
The method of claim 1 wherein said three connected wall portions form a channel and said wall portions are severed so as to form said upper flange extending outwardly from said wall and said lower flange extending outwardly from a wall portion associated with said bathtub and extending above said bathtub said lower flange terminating in a portion extending at an angle to said lower flange in a direction away from said bathtub so as to prevent water from entering a joint between said upper and lower flanges and flowing behind the bathtub when said wall and said tub are secured together through said upper and lower flanges.
Claim 6
Dependent Claim
31 words
The method of claim 1 with the additional steps of assemblying said wall and said bathtub by mating said upper and lower flanges and securing said flanges together with mechanical fasteners.
Claim 7
Dependent Claim
13 words
The method of claim 5 including securing said flanges together with threaded fasteners.
Claim 8
Dependent Claim
11 words
The method of claim 6 wherein said threaded fasteners are bolts.
