Description

The present invention relates to a hinge device for supporting a door provided at a front end of a cabinet such as a kitchen.

2. Description of the Related Art As a conventional hinge device of this type, one having a structure as shown in FIG. 7 is known. Hereinafter, referring to the drawings, 1 is a front opening 3 of a cabinet body 2.
Is a door that closes the door 1, and the upper and lower ends of one end of the door 1 are supported by a pair of hinge devices 4.

Each hinge device 4 is attached to the front end surface of the cabinet main body 2 with a screw, and a main body side metal fitting 5 is pivotally attached to the main body side metal fitting 5 with a shaft 6 and is screwed to both upper and lower end surfaces of the door 1. A shaft 6 which is composed of a door-side metal fitting 7 and which pivotally connects both metal fittings 5, 7 is projected from the door-side metal fitting 7 and is caulked at its tip in a state of being fitted into the shaft hole 8 of the main body-side metal fitting 5. And both brackets 5,
7 was composed in a connected state.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention When the door 1 is attached to the cabinet body 2 by using the hinge device 4 having the above-described configuration, first, the door-side metal fittings 7 of the hinge device 4 are attached to the upper and lower ends of either one of the left and right ends of the door 1, respectively. Is fastened with screws, and in that state, the door 1 is brought closer to the front opening 3 of the cabinet body 2, and the shaft 6 is attached to the door side metal fitting 7.
The metal fittings 5 on the main body, which are connected with each other, are brought into contact with the front end surface of the cabinet main body 2 while supporting the door 1 and fixed with screws. In such a door mounting operation, the weight of the door 1 must be supported by hand, and the cabinet main body 2 must be screwed to be connected, which is troublesome.

The present invention solves such a problem, and an object of the present invention is to make it possible to efficiently attach a door to a cabinet body.

Means for Solving the Problem The present invention for solving the problem is a hinge device for rotatably supporting a door that can open and close a front opening of a cabinet body with respect to the cabinet body, and a lower end portion of the door. The main body side has a door side metal fitting that is attached to the cabinet, a main body side metal fitting that has a plate portion that is attached to the lower end of the cabinet main body and that receives the lower end of the door, and a shaft hole into which a shaft protruding from the lower side of the door side metal fitting is inserted. The bearing member is fixed to the metal fitting.

With this configuration, there is no need to attach the door to the cabinet body while supporting the weight of the door with your hands.
The door can be mounted while the door is received by the metal fittings on the cabinet body side, and the workability can be improved.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 6, 11 is a door that closes the front opening 13 of the cabinet main body 12, and the upper and lower ends on either one of the left and right ends of the door 11 (the left end in the embodiment shown in the drawings) are respectively. It is supported by separate hinge devices 14,15.

The upper hinge device 14 is a body side metal fitting 16 that is screwed to the front end surface of the upper end of the cabinet body 12 and a door side metal fitting that is screwed to the upper end of the door 11 and has a shaft 17 protruding upward.
The shaft 17 can be fitted into the shaft hole 19 of the main body side metal fitting 16 from below.

On the other hand, the lower hinge device 15 includes a main body side metal member 20 which is fixed to the front end surface of the lower end of the cabinet main body 12 with a screw and a door.
Two shafts 21 and 22 that are screwed to the lower end of 11 and project downward
A door side metal fitting 23 provided with a main body side metal fitting 20 and a shaft hole 24 which is screwed to the main body side metal fitting 20 and into which one of the two shafts 21, 22 is fitted. And a resin bearing member (26) having a claw portion (25) that is elastically engaged and disengaged. More specifically, the main body side metal fitting 20 integrally includes a horizontal plate portion 27 that receives the lower end of the door 11, and a plate portion 28 that is bent downward from the front end of the plate portion 27.
A long hole 29 for mounting the bearing member 26 and a screw hole 30 for adjusting the front-back inclination of the door 11 are formed in the plate portion 28 bent downward. The bearing member 26 is brought into contact with the back surface of the plate portion 28 and is screwed into the plate portion 28 through the elongated hole 29.
Fixed to. Reference numeral 32 is a screw screwed into the screw hole 30 and the tip of the screw contacts the bearing member 26 to adjust the position of the bearing member 28 with respect to the plate portion 28, that is, the main body side fitting 20.

Next, the order of attaching the door 11 to the cabinet body 12 having the above configuration will be described.

First, door side fittings 18 and 23 are attached to the upper and lower ends of the door 11, respectively, and main body side fittings 16 and 20 are also attached to the upper and lower ends of the cabinet body 12. Door 11 in this state
Close to the cabinet main body 12 side, and attach the shaft 17 of the door side metal fitting 18 at the upper left end of the door 11 to the cabinet main body metal fitting 12 of the cabinet main body 12.
After being fitted into the shaft holes 19 of 16 from below, the lower end of the left end portion of the door 11 is placed on the plate portion 27 of the main body side metal fitting 20 of the cabinet main body 12. At this time, the two shafts 2 of the door side metal fitting 23 at the lower end of the door 11
1, 22 are located on both sides of the plate portion 27, and in this state, the shaft hole 24 of the bearing member 26 is fitted to the one shaft 21, and the claw portion 25 is engaged with the other shaft 22. Then, the bearing member 26 is brought into contact with the back surface of the plate portion 28. In this state, the bearing member 26 is fixed by the screw 31 screwed into the long hole 29 of the plate portion 28. At this time, the shaft hole 24 is formed in the bearing member 26 with respect to the plate portion 28 of the main body side metal fitting 20, and
It is adjusted to the left and right with the long hole 29 so that it is located on the same vertical line as 19. Further, when the door 11 is warped and the door 11 is tilted at both upper and lower ends, the tip of the screw 32 screwed into the screw hole 30 of the plate portion 28 is attached to the bearing member 26.
The front and rear inclination of the door 11 can be corrected by pressing the door 11 to adjust the gap between the plate portion 28 and the bearing member 26.

As described above, the attachment of the door 11 to the cabinet body 12 is completed, and the other shaft 22 projecting from the door 11 side in the closed state of the door 11 is rotated around the one shaft 21 by the rotation of the door 11. When the door 11 is moved and is closed, the claw portion 25 of the bearing member 26 is elastically engaged to maintain the closed state of the door 11.

By the way, in the above-mentioned embodiment, the upper end side of the door 11 is supported by the conventionally known general hinge device 14,
The upper end side of 11 may be supported by a hinge device similar to the hinge device 15 on the lower end side.

As described above, according to the present invention, there is no need to attach the door to the cabinet body while supporting the weight of the door by hand, and the door is received by the metal fittings on the cabinet body side. Installation work can be performed, and workability can be improved.
