Abstract

Abstract A pinless hinge wherein a spirally configured hollow receiver has engaged therein an arcuate engaging member which is movable along and in the spiral hollow of the receiver for relative swinging movement between the receiver and engaging member. The pinless hinge includes a plurality of limit stops, one of which receives most of the load thereby minimizing damage to the other limit stops which serve functions in addition to this stopping. A plurality of beads is located in the relative path of movement between the receiver and engaging member to improve the fit therebetween eliminating play. The receiver may be constructed in any of several shapes to simultaneously engage a plurality of engaging members.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 129 words
An improved pinless hinge construction comprising, in combination: first and second longitudinally extending members adapted to be slipped together axially to form said pinless hinge; said first member comprising at least one substantially planer portion and a hollow receiver portion extending therefrom of substantially arcurate configuration; said second member comprising at least one substantially planer portion, a substantially arcurate portion extending therefrom, and an engaging portion substantially of arcurate confirguration and extending from said arcurate portion; a plurality of bead means disposed between said hollow receiver portion of said first member and said engaging portion of said second member for minimizing play and providing a smooth rotatable fit between said hollow receiver portion and said engaging portion; and limit stop means limiting the rotational movement of said first member.
Claim 2
Dependent Claim 129 words
An improved pinless hinge construction comprising, in combination: first and second longitudinally extending members adapted to be slipped together axially to form said pinless hinge; said first member comprising at least one substantially planer portion and a hollow receiver portion extending therefrom of substantially arcurate configuration; said second member comprising at least one substantially planer portion, a substantially arcurate portion extending therefrom, and an engaging portion substantially of arcurate confirguration and extending from said arcurate portion; a plurality of bead means disposed between said hollow receiver portion of said first member and said engaging portion of said second member for minimizing play and providing a smooth rotatable fit between said hollow receiver portion and said engaging portion; and limit stop means limiting the rotational movement of said first member.
Claim 3
Dependent Claim 129 words
An improved pinless hinge construction comprising, in combination: first and second longitudinally extending members adapted to be slipped together axially to form said pinless hinge; said first member comprising at least one substantially planer portion and a hollow receiver portion extending therefrom of substantially arcurate configuration; said second member comprising at least one substantially planer portion, a substantially arcurate portion extending therefrom, and an engaging portion substantially of arcurate confirguration and extending from said arcurate portion; a plurality of bead means disposed between said hollow receiver portion of said first member and said engaging portion of said second member for minimizing play and providing a smooth rotatable fit between said hollow receiver portion and said engaging portion; and limit stop means limiting the rotational movement of said first member.
Claim 4
Dependent Claim 129 words
An improved pinless hinge construction comprising, in combination: first and second longitudinally extending members adapted to be slipped together axially to form said pinless hinge; said first member comprising at least one substantially planer portion and a hollow receiver portion extending therefrom of substantially arcurate configuration; said second member comprising at least one substantially planer portion, a substantially arcurate portion extending therefrom, and an engaging portion substantially of arcurate confirguration and extending from said arcurate portion; a plurality of bead means disposed between said hollow receiver portion of said first member and said engaging portion of said second member for minimizing play and providing a smooth rotatable fit between said hollow receiver portion and said engaging portion; and limit stop means limiting the rotational movement of said first member.
Claim 5
Dependent Claim 18 words
An improved hinge according to claim 1, wherein said bead means are integrally formed with said engaging portion.
Claim 6
Dependent Claim 19 words
The improved hinge according to claim 1, wherein said limit stop means is integrally formed with said engaging portion.
Claim 7
Dependent Claim 43 words
The improved hinge according to claim 3, wherein a secondary limit stop means is provided between said substantially arcurate portion and said engaging portion and is adapted for limiting the movement of a longitudinal edge of said planer portion of said first member.
Claim 8
Dependent Claim 36 words
The improved hinge according to claim 4, wherein a further limit stop means is provided by an edge formed at about the intersection of said planer portion and said substantially arcurate portion of said second member.
