Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A resilient, unitary hinge for a commode or the 176 like comprising a main body section, upper flange means extending forwardly from said main body section for mounting a commode lid, intermediate flange means also extending forwardly from said main body section for mounting a commode seat, and lower flange means extending rearwardly from said main body section for mounting said hinge on a commode bowl, said main body section of said hinge being formed with a first longitudinal groove between said intermediate and upper flange means for permitting pivotal movement of said upper flange means relative to said intermediate flange means about an axis adjacent the apex of said first longitudinal groove, said first longitudinal groove extending the entire length of said main body section in the region thereof containing said groove, and a second longitudinal groove between said intermediate and said lower flange means for permitting pivotal movement of the former relative to the latter about an axis adjacent the apex of said second longitudinal groove, said second longitudinal groove extending the entire length of said main body section, whereby the bearing forces on such hinge through said grooves are absorbed to a maximum degree due to the length and spacing of said grooves.
Claim 2
Dependent Claim
