Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a head plate in a drawer with a latching device.

[Problems that conventional technology and ideas try to solve]

BACKGROUND OF THE INVENTION Various configurations have been devised in the past in which a latch device is provided on the inside of a mirror panel of a drawer provided on the body of furniture such as a cabinet so as to be movable back and forth.

On the other hand, it is known, for example, from Japanese Utility Model Publication No. 53-25705, that the end plate of the drawer is made of synthetic resin and integrally molded.

By the way, configuring the latch body of the latch device to be easily attached to the end plate is as follows:
This is an important matter in order to simplify the manufacturing process of the drawer, and one of the prior technologies is the
In Japanese Patent No. 161377, the side part of the front plate of the mirror plate is folded inward to form an appropriate space, and a latch body that is biased in the direction of engaging with the furniture body is installed in the space in advance. A configuration for inserting a frame is disclosed.

Since this end plate is fixed so that its center back side is covered by the back plate, which is the front end in the drawer direction, in the event of an accident such as the latch body breaking, parts such as the latch body and biasing spring can be replaced. In order to do this, it is necessary to remove the entire mirror plate from the back plate and then take out parts such as the latch body, which poses a problem in that the replacement work is time-consuming.

The present invention aims to solve this problem.

[Means for solving problems]

Therefore, in the present invention, the end plate of the drawer is integrally formed with a horizontally U-shaped cross section consisting of a front plate and a peripheral frame surrounding the front plate, and is open to the rear. A reinforcing rib is provided rearwardly protruding on the front plate, and a latch body mounting portion is provided on the back side of the front plate between the left and right sides of the surrounding frame and the reinforcing rib, and the back side of the end plate sandwiched between the left and right pair of reinforcing ribs is provided. The central part is covered by the front part of the drawer body, and the back cover plate covering the attachment part of the latch body is configured to be detachably engaged with the surrounding frame and the reinforcing rib.

[Functions and effects of the idea]

In the present invention, the front plate and the surrounding frame are integrally molded to have a substantially U-shaped cross section and an open rearward shape.
Since the reinforcing ribs are protruded from at least the right and left sides of the back surface of the front plate, the peripheral frame and the reinforcing ribs work together to prevent the front plate from being bent and deformed even if the front plate is thin and wide.

A latch body mounting portion is provided between the left and right sides of the surrounding frame and the reinforcing rib, and the latch body mounting portion is removably covered by the back cover plate. With it removed,
Necessary parts such as the latch body can be easily assembled using the large open area on the back of the mirror plate.

The built-in latch body attachment part is removably covered by the back cover plate, but since it has come off laterally from the attachment point to the front end of the drawer body, it cannot be removed after the end plate is attached to the drawer body. Also, only the back cover plate can be removed.

Therefore, when replacing parts or adjusting the movement of the attachment part of the latch body, by removing the back cover plate, the attachment part is exposed and each part can be directly observed or adjusted. It can be replaced, making the work extremely easy.

Then, as shown in FIGS. 2 and 14,
The end plate 1 has the handle frame 4, the front plate 1a, and the surrounding frame 1b integrally formed, and the shaft support 17 and the support frame 11 are also opened rearward, so that the operating body 6 and the receiving body 23 can be connected to each other. The drawer body 14 can be attached to the back plate 3 of the drawer main body 2 in a state where it is assembled in advance on the back side of the mirror plate 1.

Further, on the left and right back surfaces of the mirror plate 1 that protrude to the sides of the back plate 3, there are removable back cover plates 30 that fit into the surrounding frame 1b and whose claws 31 fit into the locking holes 32 of the reinforcing ribs 1c. , 30.

Reference numeral 36 designates a through hole formed in the rear cover plate 30 through which the free end of the latch body 14 can protrude rearward.

The lock 33, whose front side faces the hole in the front plate 1a of the mirror plate, is supported by being surrounded by a frame 34 that projects rearward from the rear surface of the front plate 1a, and is engaged with a locking claw of the frame 34. On the other hand, it is pressed and fixed by the protrusion 35 of the back plate 3.

In this way, in the case where the latch body 14 is attached to the back surface of the end plate 1 via the latch attachment part consisting of the support frame 11 and the receiver 23, the interlocking rod and the latch body can rotate integrally. By bringing the actuating body attached to the operating piece facing the pull hole of the end plate into contact with one end of the interlocking rod, the latch body can be moved in the unlatching direction by operating the operating piece from the front side of the end plate. It can be rotated.

The end plate is integrally formed with the front plate and the surrounding frame so that it has a substantially U-shaped cross section and is open toward the rear, and reinforcing ribs are provided protruding from at least both left and right sides of the back surface of the front plate, so that the front plate and the surrounding frame are integrally formed. Together with the reinforcing ribs, even if the front plate is thin and has a wide surface, it will not be bent or deformed.

Further, since a latch body mounting portion is provided between the left and right sides of the surrounding frame and the reinforcing rib, and the latch body mounting portion is removably covered by the back cover plate, the back cover plate is When removed,
Necessary parts such as the latch body can be easily assembled using the large open area on the back of the mirror plate.

The built-in latch body attachment part is removably covered by the back cover plate, but since it has come off laterally from the attachment point to the front end of the drawer body, it cannot be removed after the end plate is attached to the drawer body. Also, only the back cover plate can be removed.

Therefore, when replacing parts or adjusting movement of the attachment part of the latch body, by removing the back cover plate,
By exposing the mounting portion, each component can be directly observed, adjusted, and replaced, making work extremely easy.

In addition, if a stopper piece is provided on the other side of the receiver to restrict the rotation angle of the latch, the protruding posture of the latch that can freely rotate with respect to the receiver will always be maintained in a constant state. This makes it extremely easy to attach it to the back of the mirror plate.
