Abstract
Abstract There is disclosed a hinge assemblage for handle straps of handbags, luggage, attache cases and similar items. The hinge assembly is formed by a pair of rigid members each of which mounts two locking pins. These locking pins have an outer surface which is partly circularly curved and partly flat. Each flat surface has thereon a row of saw teeth. Placement of the locking pins in superimposition causes the saw teeth on the locking pins to engage each other thereby positively preventing relative sliding of the locking pins. The superimposed locking pins are held in position by sleeves fitted upon the toothed portions of the locking pins. The curved and the flat pin portions are so correlated that each two pins define a cylindrical configuration when placed in superimposition. The result of locking the pins and thus the hinge members together is a hinge.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
A hinge device for handle straps of handbags, luggage, attache cases and similar items using handle straps, said device comprising in combination: a pair of rigid hinge members, each of said hinge members including A base part and two locking pins extending from the base part normal thereto and in mutually parallel spaced apart relationship, each of said locking pins having a circularly curved surface portion and a flat surface portion, each of said flat surface portions including protrusions and recesses, the protrusions and recesses on each locking pin on one of the hinge members being engageable with the protrusions and recesses on one of the locking pins on the other hinge member, placement of the respective locking pin on the two hinge members in superimposition complementing the pins to define a cylindrical configuration and preventing lengthwise displacement of the respective pins relative to each other; and a pair of locking sleeves, each of said sleeves being fittable upon two superimposed locking pins for locking said pins in the superimposed position, thereby defining a hinge device of closed peripheral outline.
Claim 2
Dependent Claim
180 words
A hinge device for handle straps of handbags, luggage, attache cases and similar items using handle straps, said device comprising in combination: a pair of rigid hinge members, each of said hinge members including A base part and two locking pins extending from the base part normal thereto and in mutually parallel spaced apart relationship, each of said locking pins having a circularly curved surface portion and a flat surface portion, each of said flat surface portions including protrusions and recesses, the protrusions and recesses on each locking pin on one of the hinge members being engageable with the protrusions and recesses on one of the locking pins on the other hinge member, placement of the respective locking pin on the two hinge members in superimposition complementing the pins to define a cylindrical configuration and preventing lengthwise displacement of the respective pins relative to each other; and a pair of locking sleeves, each of said sleeves being fittable upon two superimposed locking pins for locking said pins in the superimposed position, thereby defining a hinge device of closed peripheral outline.
Claim 3
Dependent Claim
52 words
The hinge device according to claim 1 wherein each of the sleeves is lengthwise slotted and made of elastic material, said sleeves engaging the respective superimposed locking pins with a pressure fit thereby biasing said protrusions and recesses toward each other but yielding to a pull on the pins in opposite direction.
Claim 4
Dependent Claim
71 words
The hinge device according to claim 1 wherein each of said locking pins has at its end adjacent to the respective hinge member a cylindrical portion, the length of said portions, the length of the sleeves and the outer diameters thereof being so correlated that upon fitting sleeves upon superimposed flat pin portions the respective two cylindrical portions and the respective sleeve define a continuous cylindrical surface of substantially uniform diameter.
Claim 5
Dependent Claim
56 words
The hinge device according to claim 1 wherein each of said hinge members is an elongate bar of substantially oval outline in its lengthwise direction and having a substantially semi-circular cross-section, the side of bars mounting said pins being flat and the opposite side being gradually reduced in thickness toward the lengthwise ends of the bars.
Claim 6
Dependent Claim
21 words
The hinge device according to claim 1 wherein said hinge members and said locking pins define a continuous substantially rectangular outline.
Claim 7
Dependent Claim
30 words
The hinge device according to claim 1 wherein said protrusion and recesses on the flat surfaces portions of the locking pins are in the form of transversely disposed saw teeth.
Claim 8
Dependent Claim
21 words
The hinge device according to claim 6 wherein the saw teeth on each locking pin are disposed in a lengthwise row.
Claim 9
Dependent Claim
22 words
The hinge device according to claim 7 wherein the steep flanges of the saw teeth face the end of the locking pins.
