BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure of a door which can be suitably used for steel furniture, and more particularly to a hinge structure of a door which can be mounted on a furniture body by one-touch operation.

[0002]

2. Description of the Related Art In a steel furniture such as a library or a locker having a rotating door, a hinge structure for pivotally connecting the door to a furniture body is used. As this hinge structure, a structure in which a pair of brackets rotatably attached to a hinge shaft are screwed to the door and the furniture body, respectively, is general. In addition, as a simple hinge structure, a lower hinge hole is formed on the upper surface of the bottom plate portion of the furniture main body, and an upper hinge hole is formed on the lower surface of the top plate portion, and a hinge shaft rotatably fitted into these hinge holes is projected. There is also known a configuration in which an installed base plate is screwed to a door.

[0003]

All of the above-mentioned conventional hinge structures need to be screwed to a furniture body, a door, or the like, which causes a reduction in workability of attaching the door to the furniture body. .

Accordingly, it is an object of the present invention to provide a hinge structure of a door in which a door can be attached to a furniture body by one-touch operation.

[0005]

In order to achieve the above object, an invention according to claim 1 is characterized in that upper and lower hinges in which one side of a door is opened to a lower surface of a top plate and an upper surface of a bottom plate of a furniture body. In a hinge structure of a door rotatably connected via upper and lower hinge shafts fitted into holes, the door has an upper bent edge facing a lower surface of a top plate portion of the furniture body and the upper bent edge below the upper bent edge. And an upper hinge plate provided in parallel with the upper reinforcing plate, and a lower bent edge facing the upper surface of the bottom plate portion of the furniture main body and a lower reinforcing plate provided above and parallel to the lower bent edge. Each has a lower hinge hole, the lower hinge hole of the door and the furniture body from above the lower hinge axis,
Also, the upper hinge shaft is inserted from below into the upper hinge hole of the door and the furniture body, and the stopper made of the upper hinge shaft above the upper reinforcing plate prevents the upper hinge shaft from coming off. Features.

According to a second aspect of the present invention, in the door hinge structure of the first aspect, the stopper has a fitting groove having a substantially C-shaped cross section which can be snap-fitted to the upper hinge shaft from the side. It is characterized by the following.

According to a third aspect of the present invention, there is provided the door hinge structure according to the first aspect, wherein a lower hinge hole of the furniture main body has a flange at an outer periphery at one end from above and a lower hinge hole has a flange at an outer periphery from below. A plastic sleeve is fitted, and the tip of the hinge shaft is fitted to the sleeve.

[0008]

In the hinge structure for a door according to the first aspect, the operation of inserting the upper and lower hinge shafts into the upper hinge hole and the lower hinge hole, respectively, and holding the stopper on the upper hinge shaft above the upper reinforcing plate. The door can be easily and rotatably attached to the furniture body only by performing the above operation.

In the hinge structure for a door according to the second aspect, the stopper can be easily hung on the upper hinge shaft by one-touch operation, and a tool is not required, thereby improving workability.

In the hinge structure of the door according to the third aspect, the upper and lower hinge shafts are respectively held through the sleeves with respect to the hinge hole on the lower surface of the top plate and the hinge hole on the upper surface of the bottom plate of the furniture body. The rattling of the hinge shaft can be prevented. In addition, since the collar of the sleeve is interposed between the lower bent edge of the door and the upper surface of the bottom plate of the furniture main body, and between the upper bent edge of the door and the lower surface of the top plate of the furniture main body, the door is closed. It can be rotated smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment in which the hinge structure according to the present invention is applied to a steel cabinet. Referring to these drawings, the cabinet includes a cabinet body 1 having an open front surface, and a pair of left and right double doors 2 and 3 rotatably mounted on the front surface of the cabinet via a hinge structure described later. . Since the hinge structure applied to both doors 2 and 3 has the same configuration,
Here, only the hinge structure applied to one door 3 will be described.

The cabinet body 1 includes left and right side plates 4,5.
, A top plate part 6, a bottom plate part 7, and a rear plate part (not shown). As shown in detail in FIG. 3, the top plate portion 6 includes a main surface plate 8 having a front end bent downward, a front reinforcing plate 9 fixed to an inner surface of the front end, and an outer surface of the front end of the main surface plate 8. And an upper front frame 10 fixed to the side. As shown in detail in FIG. 4, the bottom plate 7 has a main surface plate 11 having a front end bent upward, and a front reinforcing plate 12 fixed to the inner surface of the front end.
And a lower front frame 13 fixed to the outer surface of the front end of the main face plate 11 and protruding forward from the front ends of the side plates 2 and 3. The upper front frame 10 and the lower front frame 13 project forward from the front ends of the side plates 2 and 3, and the doors 2 and 3 are arranged between the upper front frame 10 and the lower front frame 13. Have been.

As shown in detail in FIGS. 3 and 4, the door 3
Is a main face plate 1 whose upper, lower, left and right ends are bent rearward
The upper bent edge 15 formed by bending the upper end of the main face plate 14 has an upper front frame 10
And the lower bent edge 16 formed by bending the lower end of the main face plate 14 faces the upper surface of the lower front frame 13 of the cabinet body 1 (the upper surface of the bottom plate portion). Inside the upper end of the main face plate 14 of the door 3 is an upper bent edge 1
An upper reinforcing plate 17 extending in parallel with 5 is fixed, and a lower reinforcing plate 18 extending in parallel with the lower bent edge 16 is fixed inside the lower end of the main face plate 14.

Next, the hinge structure will be described in detail. An upper hinge hole 19 is formed on the lower surface of the upper front frame 10 of the cabinet body 1, and a lower hinge hole 21 is formed on the upper surface of the lower front frame 13. Door 3
