Abstract
Abstract Hinge construction for joining two relatively movable members. The hinge is particularly adapted for construction from plastics using known molding techniques and for incorporation into plastic molded parts. Identical hinge halves are formed to present, in each half, a planar mounting portion and a hinge tube section. The planar mounting portion is characterized by a peripheral tongue which is received within a peripheral groove of a socket in the respective member. The hinge tube section of each hinge half has opposed protuberances at one end which extend part way along the length of the section and into the tubular opening. When two hinge halves are placed with their tube sections aligned, the latter form a tubular hinge opening. A hinge pin is provided with opposed grooves which are complemental to the protuberances and disposed for alignment with the latter. The hinge pin may thus be inserted into the tubular hinge opening and held therein upon rotation to a nonaligning position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
200 words
Hinge construction comprising: a first hinge half presenting a generally planar mounting portion and an integral first hinge tube section, said first hinge tube section presenting a protuberance extending from one end of said section into the tubular opening along a portion of the length of said section; a second hinge half presenting a generally planar mounting portion and an integral second hinge tube section, said second hinge tube section presenting a protuberance extending from one end of said section into the tubular opening along a portion of the length of said section; said first and second hinge halves being adapted to be disposed in mating relationship with said first and second hinge tube sections being aligned to present a tubular hinge opening with said protuberances at opposite ends of the opening; and a hinge pin having a longitudinally extending slot disposed therein generally complemental in configuration to the shape of said protuberances whereby said pin may be inserted within said tubular hinge opening when said slot is aligned with the protuberance at one end of said opening and held therein upon rotation to a nonaligning position to cooperate with said first and second hinge halves to present a hinge.
Claim 2
Dependent Claim
200 words
Hinge construction comprising: a first hinge half presenting a generally planar mounting portion and an integral first hinge tube section, said first hinge tube section presenting a protuberance extending from one end of said section into the tubular opening along a portion of the length of said section; a second hinge half presenting a generally planar mounting portion and an integral second hinge tube section, said second hinge tube section presenting a protuberance extending from one end of said section into the tubular opening along a portion of the length of said section; said first and second hinge halves being adapted to be disposed in mating relationship with said first and second hinge tube sections being aligned to present a tubular hinge opening with said protuberances at opposite ends of the opening; and a hinge pin having a longitudinally extending slot disposed therein generally complemental in configuration to the shape of said protuberances whereby said pin may be inserted within said tubular hinge opening when said slot is aligned with the protuberance at one end of said opening and held therein upon rotation to a nonaligning position to cooperate with said first and second hinge halves to present a hinge.
Claim 3
Dependent Claim
53 words
The invention of claim 1, wherein each of said first and second hinge tube sections presents first and second opposed protuberances extending from one end of the section into the tubular opening, and said hinge pin has opposed longitudinally extending slots generally complemental to said protuberances and disposed for alignment with the latter.
Claim 4
Dependent Claim
48 words
The invention of claim 2, wherein said hinge pin is provided with an extension of reduced diameter at each end, each of said extensions adapted to be received between said protuberances of each of said hinge tube sections when said pin is inserted in said tubular hinge opening.
Claim 5
Dependent Claim
24 words
The invention of claim 3, wherein each of said first and second hinge tube sections comprises first and second spaced apart hinge tube components.
Claim 6
Dependent Claim
87 words
The invention of claim 1, wherein said hinge construction is adapted for coupling first and second members in hinged relationship, each of said members having a socket along the edge to be hinged with a peripheral groove extending at least part way around the socket and wherein each of said planar mounting portions of said first and second hinge halves respectively is complemental in configuration to the socket in a respective member and is characterized by a peripheral tongue adapted to be received in the peripheral groove.
Claim 7
Dependent Claim
22 words
The invention of claim 5, wherein each of said sockets and each of said planar mounting portions is of generally polygonal configuration.
Claim 8
Dependent Claim
34 words
The invention of claim 6, wherein one side of each of said sockets is free of said peripheral groove to allow each of said planar mounting portions to be slid into its respective socket.
Claim 9
Dependent Claim
23 words
The invention of claim 7, wherein is included auxiliary fastening means for securing each of said planar mounting portions to the respective members.
