Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
205 words
A hinge joint including first and second cooperable hinge members, I. The first hinge member comprising: (a) an elongated frame adapted to be attached to a first part to be hinged, and (b) a bead extending longitudinally along the frame, the bead having a substantially circular cross-sectional shape, and the bead having a recess in its exterior surface, the recess extending for the length of the bead, and II. the second hinge member comprising: (c) an elongated frame adapted to be attached to a second part to be hinged to the first part, and (d) a concave channel extending longitudinally along the frame (c), the channel being sized to rotatably accommodate the bead within it, the channel having a longitudinal opening of a width such that when one longitudinal edge of the opening is located in the recess of the bead, the bead can pass between the longitudinal edges of the opening into the channel to assemble the hinge members, and when the hinge members are thereafter relatively rotated so that the one edge of the opening is out of registry with the recess, the bead cannot pass between the longitudinal edges of the opening, whereby the hinge members remain assembled in relatively rotatable condition.
Claim 2
Dependent Claim
205 words

The first hinge member comprising: (a) an elongated frame adapted to be attached to a first part to be hinged, and (b) a bead extending longitudinally along the frame, the bead having a substantially circular cross-sectional shape, and the bead having a recess in its exterior surface, the recess extending for the length of the bead, and II. the second hinge member comprising: (c) an elongated frame adapted to be attached to a second part to be hinged to the first part, and (d) a concave channel extending longitudinally along the frame (c), the channel being sized to rotatably accommodate the bead within it, the channel having a longitudinal opening of a width such that when one longitudinal edge of the opening is located in the recess of the bead, the bead can pass between the longitudinal edges of the opening into the channel to assemble the hinge members, and when the hinge members are thereafter relatively rotated so that the one edge of the opening is out of registry with the recess, the bead cannot pass between the longitudinal edges of the opening, whereby the hinge members remain assembled in relatively rotatable condition.
Claim 3
Dependent Claim
33 words
A hinge joint according to claim 1 wherein the frame of the first hinge member includes two mutually perpendicular flanges, the bead being located near the line of intersection between the frame flanges.
Claim 4
Dependent Claim
34 words
A hinge joint according to claim 2 wherein the bead includes a slanted portion extending at an angle to one of the frame flanges, the slanted portion extending into the recess of the bead.
Claim 5
Dependent Claim
42 words
A hinge joint according to claim 2, including a shell partially surrounding the bead, the shell interconnecting the two legs of the frame and defining between itself and the bead a chamber for slidably receiving the channel of the second hinge member.
Claim 6
Dependent Claim
25 words
A hinge joint according to claim 4 wherein the chamber has an increased width at its open end adjacent to one of the frame flanges.
Claim 7
Dependent Claim
36 words
A hinge joint according to claim 1 wherein the concave channel of the second hinge member has the shape of a partial circular cylinder, the channel extending for more than one-half the circumference of the cylinder.
Claim 8
Dependent Claim
37 words
A hinge joint according to claim 1 wherein the frame of the second hinge member includes two flanges which meet at an obtuse angle, the channel being located near the line of intersection of the frame flanges.
Claim 9
Dependent Claim
31 words
A hinge joint according to claim 1 wherein the internal radius of the channel is about equal to the external radius of the bead in the region not having the recess.
