Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a hinge for suitcases, bags, etc.

(Prior Art) Synthetic resin hinges for bags are generally known, and in this type of synthetic resin hinges, one hinge structure and the other hinge member are fitted into mating parts of each other. A structure in which a convex portion and a concave portion are provided, a core shaft is passed through these concave and convex portions, and the shaft is mutually hinged is already known from Japanese Utility Model Publication No. 174420/1983.

(Problem to be solved by the invention) However, in this type of structure, in order to make the hinge parts of both hinge components strong, it is necessary to form them thickly. Since the part is shaped to protrude high towards the bottom, if the bottom of the bag touches the ground, this part may hit the ground and be damaged.In order to hold the bag vertically, the bottom studs on the bottom surface of the hinge structure should be further tightened. This required a high structure, which caused problems such as lack of stability when the bottom of the bag was placed on the ground and held vertically.

(Means for Solving the Problems) The present invention consists of a fixed side member consisting of a plastic plate portion having a recess on the lower surface, a metal plate portion fitted into the recess and riveted, and a plastic plate portion having a recess on the lower surface. The inner edges of each metal plate part of the movable side member, which is composed of a plate part and a metal plate part fitted into a recess and riveted thereto, are hinged to each other with a pivot rod so that the metal plate part can be bent freely, and the metal plate part is fitted in a recess. The present invention attempts to solve these problems by providing a hinge for suitcases, bags, etc., which has a plastic cover permanently attached to the outside of the plate part.

(Embodiment) The embodiment shown in the figure is made of a plastic plate part 8 having a recess 7 on its lower surface and a metal plate part 9 fitted into the recess 7 with rivets.
The movable side member 2 consists of a fixed side member 1 consisting of a plastic plate part 11 having a recess 10 on the lower surface and a metal plate part 12 fitted and riveted into the recess 10, and these are fixed. The inner edges of the metal plate portions 9 and 12 in the side member 1 and the movable side member 2 are hinged to each other by the shaft rod 3 so as to be bendable, and the metal plates in the fixed side member 1 and the movable side member 2 are Screw holes 14, 15 passing through the parts 9, 12 and the plastic plate parts 8, 11 are provided, and plastic covers 16, 1 are provided on the outside of the metal plate parts 9, 12 in the recess 7.
By fitting 7 irremovably, the hinge body 4
Further, bottom rivets 5 and 6 are integrally provided on the lower surfaces of the outer ends of the plastic plates 8 and 11 of the fixed side member 1 and the movable side member 2, and bottom studs 5 and 6 are also provided on the upper surfaces of the inner ends. Grooves 22 and 23 having the same shape as the outer surfaces of the protector 20 and the border frame 21 of the suitcase body 19 are provided.

In the figure, 22 and 24' indicate screw holes.

(Operations and Effects of the Invention) As described above, the present invention consists of a fixed side member consisting of a plastic plate part having a recess on the lower surface, a metal plate part fitted into the recess and riveted, and a fixed side member having a recess in the lower surface. The inner edges of the metal plate parts of the movable side member, which is made up of a plastic plate part and a metal plate part fitted into a recess and riveted thereto, are hinged to each other with a shaft rod so that they can be bent freely. The hinge part of each metal plate part does not need to be particularly thick, and therefore does not bulge out high downwards, so it will not be damaged by hitting the ground etc. when touching the ground. There is no need to make the height of the bottom studs particularly large in order to keep it floating, and the present invention can sufficiently solve the above problems. In the present invention, a plastic cover is fixed irremovably to the outside of the metal plate in the recess of the plastic plate, and the fixings used to fix the metal plate to the plastic plate are fixed. This also has the advantage that the head of the rivet is reliably covered and protected.
