Abstract
Abstract A hinge assembly for pivotally joining a cover or lid member with a base or housing member, or the like. The cover member includes a pair of coaxial and inwardly facing rod-like pivot members which are axially spaced apart and project from the lid or cover member. The base or container member includes a receptacle arrangement, including an elongate locking slot and a pair of arcuate grooves formed at either end, the grooves generally defining segments of a tubular hinge knuckle for receiving the rod-like pivot members. A locking member is employed to maintain the cover in articulate assembly, said locking member comprises a base or frame segment slidably insertable in the elongate locking slot, and having a pair of fingers extending outwardly of opposite sides of the base or frame segment, each said finger having arcuate inner surface portions defining generally segments of a tubular hinge knuckle. Further said base or frame segment includes a locking tab portion for snap-like engagement in the locking slot when the base portion is assembled. The respective knuckle segments on the locking member and the base member upon assembly surrounding the rod-like members on the cover, thereby to maintain said cover in pivotal assembly with the base member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A hinge assembly for pivotally joining a cover member or the like to a base member, said hinge assembly comprising: pintle means on said cover member, a locking member including a first portion defining a segment of a hinge knuckle and a second portion defining locking tab means, receptacle means in said base member including a first portion defining a segment of a hinge knuckle and a second portion defining locking slot means, said locking tab means being engageable with said locking slot means for holding said first portion of said locking member in alignment with said first portion of said base member to define a hinge knuckle surroundingly and pivotally engaging said pintle means of said cover member.
Claim 2
Dependent Claim
119 words
A hinge assembly for pivotally joining a cover member or the like to a base member, said hinge assembly comprising: pintle means on said cover member, a locking member including a first portion defining a segment of a hinge knuckle and a second portion defining locking tab means, receptacle means in said base member including a first portion defining a segment of a hinge knuckle and a second portion defining locking slot means, said locking tab means being engageable with said locking slot means for holding said first portion of said locking member in alignment with said first portion of said base member to define a hinge knuckle surroundingly and pivotally engaging said pintle means of said cover member.
Claim 3
Dependent Claim
56 words
A hinge assembly according to claim 1 wherein said pintle means comprises a pair of generally cylindrical rod-like members, and means on said cover member for holding said rod-like members generally along a common axis substantially parallel with a side surface of said cover member, and extending axially inwardly to define axially spaced apart facing edges.
Claim 4
Dependent Claim
70 words
A hinge assembly according to claim 2 wherein said locking member comprises a generally flat, frame-like member of substantially like width with said axial space between said facing edges, said first portion of said locking member comprising a pair of fingers extending oppositely laterally outwardly of said frame-like member and having curved inner surface portions for engaging at least a portion of the external side surfaces of said rod-like members.
Claim 5
Dependent Claim
86 words
A hinge assembly according to claim 3 wherein said second portion of said receptacle means comprises an elongate slot extending through a top wall of said base member and of length substantially similar to said width of said flat frame-like member, and said first portion of said base member comprises a pair of grooves extending laterally outwardly of opposite ends of said elongate slot and curving inwardly of said top wall for engaging at least a portion of the external side surfaces of said rod-like members.
Claim 6
Dependent Claim
45 words
A hinge assembly according to claim 4 wherein said locking tab portion of said locking member comprises a resilient member extending laterally outwardly of said frame-like member and resiliently yieldable for insertion through said slot for snappingly engaging an inner surface of said top wall.
Claim 7
Dependent Claim
76 words
A hinge assembly according to claim 5 wherein said means on said cover member for holding said rod-like members includes a pair of upstanding, elongate ribs generally perpendicular with said rod-like members and confluent with said rod-like members at said portions thereof remote from said facing surfaces, and said receptacle means further includes top means for engaging said rib members to define a fully opened position of said cover member with respect to said base member.
Claim 8
Dependent Claim
138 words
A hinge assembly for pivotally joining a cover member or the like to a base member, said hinge assembly comprising; pintle means formed on said cover, receptacle means formed in said base member including means defining a segment of a hinge knuckle for receiving said pintle means, and a slot, and locking member for maintaining said pintle means in assembly with said receptacle means of said base member, said locking member including, a segment insertable in said slot provided by said receptacle means, said segment including detents means for resisting removal of said locking member once assembled to said base member, and means defining a segment of a hinge knuckle complementary to that provided by said receptacle means, such that upon assembly the respective hinge knuckle segments surround said pintle means to provide for the pivotal mounting thereof.
Claim 9
Dependent Claim
138 words
A hinge assembly for pivotally joining a cover member or the like to a base member, said hinge assembly comprising; pintle means formed on said cover, receptacle means formed in said base member including means defining a segment of a hinge knuckle for receiving said pintle means, and a slot, and locking member for maintaining said pintle means in assembly with said receptacle means of said base member, said locking member including, a segment insertable in said slot provided by said receptacle means, said segment including detents means for resisting removal of said locking member once assembled to said base member, and means defining a segment of a hinge knuckle complementary to that provided by said receptacle means, such that upon assembly the respective hinge knuckle segments surround said pintle means to provide for the pivotal mounting thereof.
Claim 10
Dependent Claim
45 words
A hinge assembly as defined in claim 7 wherein said locking member segment includes a resilient tub portion having a detent formed thereon, and said slot includes a ledge portion, under which said detent is engaged upon assembly to resist removal of said locking member.
Claim 11
Dependent Claim
82 words
A hinge assembly according to claim 7 wherein said pintle means includes a pair of spaced rod-like segments projecting from said cover member toward each other, and said receptacle means first portion includes a pair of spaced arcuate grooves, with said slot interposed therebetween, and said means on said locking member defining a segment of a hinge knuckle includes a pair of arcuate grooves complementary to those of said receptacle means, disposed on opposite sides of said segment insertable in said slot.
