Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
300 words
A hinge composed of a rigid non-metallic material comprising a. a pair of hinge plates, each plate including a generally flat surface and a plurality of knuckles spaced along one edge thereof, said knuckles being spaced such that with said one edge of each of the pair of plates arranged adjacent each other the knuckles on one plate mesh with and alternate with the knuckles on the other plate, each knuckle including an opening therein positioned such that the openings are in alignment, and b. a pintle passing through said opening such that one plate may be pivoted with respect to the other, c. the flat surface of each of said plates including a plurality of embossments and a plurality of recesses, each embossment being located on a portion of said surface extending between the parts of said one edge not having said knuckles and the opposite edge thereof to strengthen said plate at the points of greatest strain during use, and each recess being located in a portion of said surface extending between the parts of said one edge having knuckles and the opposite edge thereof where said plate receives less strain during use, the size and arrangement of said recesses on each plate complementing the corresponding embossments on the other plate, d. whereby portions of each of said plates in alignment with each of said knuckles are thinner than corresponding portions of each of said plates in alignment with the edge between said knuckles, and when said plates are pivoted such that said surfaces of the plates are in contiguous relationship the embossments of each of said plates will be received in the recesses of the other plate and the overall thickness of said hinge will not be substantially greater than the combined thicknesses of the two plates.
Claim 2
Dependent Claim
300 words
A hinge composed of a rigid non-metallic material comprising a. a pair of hinge plates, each plate including a generally flat surface and a plurality of knuckles spaced along one edge thereof, said knuckles being spaced such that with said one edge of each of the pair of plates arranged adjacent each other the knuckles on one plate mesh with and alternate with the knuckles on the other plate, each knuckle including an opening therein positioned such that the openings are in alignment, and b. a pintle passing through said opening such that one plate may be pivoted with respect to the other, c. the flat surface of each of said plates including a plurality of embossments and a plurality of recesses, each embossment being located on a portion of said surface extending between the parts of said one edge not having said knuckles and the opposite edge thereof to strengthen said plate at the points of greatest strain during use, and each recess being located in a portion of said surface extending between the parts of said one edge having knuckles and the opposite edge thereof where said plate receives less strain during use, the size and arrangement of said recesses on each plate complementing the corresponding embossments on the other plate, d. whereby portions of each of said plates in alignment with each of said knuckles are thinner than corresponding portions of each of said plates in alignment with the edge between said knuckles, and when said plates are pivoted such that said surfaces of the plates are in contiguous relationship the embossments of each of said plates will be received in the recesses of the other plate and the overall thickness of said hinge will not be substantially greater than the combined thicknesses of the two plates.
Claim 3
Dependent Claim
22 words
A hinge as defined in claim 2 wherein the embossments of said plates include holes for receiving screws for mounting said hinge.
Claim 4
Dependent Claim
230 words
A hinge composed of a rigid, non-metallic material comprising a. a pair of hinge plates, each plate including a generally flat surface and a plurality of knuckles spaced along one edge thereof, said knuckles being spaced such that with said onE edge of each of the pair of plates arranged adjacent each other the knuckles on one plate mesh with and alternate with the knuckles on the other plate, each knuckle including an opening therein positioned such that the openings are in alignment, b. a hinge pin, said pin passing through said openings such that one plate may be pivoted with respect to the other, c. the flat surfaces of each of said plates including a plurality of embossments and a plurality of recesses, said recesses on one plate being sized and arranged to complement the corresponding embossments on the other plate and when said plates are pivoted into surface-to-surface relationship, each embossment and recess combination having a thickness which is less than the thickness of the plate in which the recess is formed, d. the embossments on each plate being positioned on that portion of the surface which extends away from and between the knuckles of the plate whereby the embossments on each plate provide reinforcement to the hinge plates at the points of greatest strain during use without increasing the combined thickness of the pair of hinge plates.
Claim 5
Dependent Claim
230 words
A hinge composed of a rigid, non-metallic material comprising a. a pair of hinge plates, each plate including a generally flat surface and a plurality of knuckles spaced along one edge thereof, said knuckles being spaced such that with said onE edge of each of the pair of plates arranged adjacent each other the knuckles on one plate mesh with and alternate with the knuckles on the other plate, each knuckle including an opening therein positioned such that the openings are in alignment, b. a hinge pin, said pin passing through said openings such that one plate may be pivoted with respect to the other, c. the flat surfaces of each of said plates including a plurality of embossments and a plurality of recesses, said recesses on one plate being sized and arranged to complement the corresponding embossments on the other plate and when said plates are pivoted into surface-to-surface relationship, each embossment and recess combination having a thickness which is less than the thickness of the plate in which the recess is formed, d. the embossments on each plate being positioned on that portion of the surface which extends away from and between the knuckles of the plate whereby the embossments on each plate provide reinforcement to the hinge plates at the points of greatest strain during use without increasing the combined thickness of the pair of hinge plates.
Claim 6
Dependent Claim
20 words
A hinge assembly as defined in claim 3 wherein all embossments have equal thickness and all recesses have equal depth.
Claim 7
Dependent Claim
29 words
A hinge assembly as defined in claim 3 wherein the thickness of the embossments in each plate is no greater than one-half of the thickness of the other plate.
Claim 8
Dependent Claim
22 words
A hinge as defined in claim 3 wherein the embossments of said plates include holes for receiving screws for mounting said hinge.
