Abstract
Abstract A molded article having an embedded bracket, such as a whirlpool tub, the mold and a method of molding the article. The article includes a rigid shell having a non-finish side and a finish side. The non-finish side is coated with a polymeric material. The polymeric material encloses a bracket and distributes the weight of an attached object, such as a whirlpool motor, over adjacent polymeric material. The bracket is affixed to the rigid shell in a spaced relationship and includes a surface for attaching to an object by attachment means such as a blind bolt. The bracket may also be affixed to the rigid shell by supports which are welded to the rigid shell.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
A method for coating a preformed rigid sanitary fixture shell with a hardenable material to form a molded sanitary article having an attachment means for attaching an object to said sanitary article, said shell including an underside and including a bracket for affixing said attachment means thereto, comprising the steps of affixing a bracket to the underside of said rigid shell, loading said rigid shell with bracket affixed into a mold receptor to define a void therebetween, introducing said hardenable material into said void to coat the underside of said rigid shell and to completely enclose the entire bracket affixed thereto, permitting said hardenable coating to harden on the underside of the rigid shell and bracket, removing the coated rigid shell from said mold receptor after the hardenable material has sufficiently hardened, boring an aperture through said bracket and said hardenable material and affixing said attachment means to said bracket through said aperture to permit said object to be supported on the underside of said rigid shell by said attachment means, the weight of the object supported by said attachment means being distributed over the coated underside of the rigid shell.
Claim 2
Independent Claim
191 words
A method for coating a preformed rigid sanitary fixture shell with a hardenable material to form a molded sanitary article having an attachment means for attaching an object to said sanitary article, said shell including an underside and including a bracket for affixing said attachment means thereto, comprising the steps of affixing a bracket to the underside of said rigid shell, loading said rigid shell with bracket affixed into a mold receptor to define a void therebetween, introducing said hardenable material into said void to coat the underside of said rigid shell and to completely enclose the entire bracket affixed thereto, permitting said hardenable coating to harden on the underside of the rigid shell and bracket, removing the coated rigid shell from said mold receptor after the hardenable material has sufficiently hardened, boring an aperture through said bracket and said hardenable material and affixing said attachment means to said bracket through said aperture to permit said object to be supported on the underside of said rigid shell by said attachment means, the weight of the object supported by said attachment means being distributed over the coated underside of the rigid shell.
Claim 3
Dependent Claim
28 words
The method of claim 1, wherein the bracket is affixed to the rigid shell by welding, brazing, soldering, gluing, or mechanically affixing the bracket to the rigid shell.
Claim 4
Dependent Claim
30 words
The method of claim 1 wherein the shape of the hardenable material embedding the bracket forms a positive draft angle, facilitating removal of the molded article from the mold receptor.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein said attachment means comprises a bayonet attachment means.
Claim 6
Dependent Claim
12 words
The method of claim 1, wherein said attachment means comprises a bolt.
Claim 7
Dependent Claim
12 words
The method of claim 5, wherein said bolt is a blind bolt.
Claim 8
Dependent Claim
13 words
The method of claim 1, wherein said rigid shell is a sanitary fixture.
Claim 9
Dependent Claim
21 words
The method of claim 1, wherein said hardenable material is selected from the group consisting of polymeric material and glass fibers.
