Description

[Detailed description of the invention] [Field of industrial application] The present invention is a cabinet in which a door is rotatably pivoted on either the right or left side of the opening edge of a furniture body with an open front. In furniture such as
The present invention relates to a latch device that automatically locks the door to the furniture body when the door is closed.

[Conventional technology]

Conventionally, a door latch device for this type of furniture has been constructed by forming an engaging part at the edge of the opening in the furniture body, and by hollowing out the periphery of the door, as described in, for example, Japanese Utility Model Application Publication No. 58-5567. A latch body is rotatably formed in a hollow space at the periphery of the door and has a kick-in locking pawl projecting backward from the inner surface of the door, and the latch body is rotatably provided with a kick-in locking pawl portion projecting backward from the inner surface of the door. When the door is closed, the kick-in locking pawl portion of the latch body engages with the engaging portion of the furniture body by being biased by a spring so as to rotate in the direction in which the pawl portion engages with the engaging portion of the furniture body. The door is configured to automatically push into engagement with the joint, and is further provided with a pull in the opening of the door that can be rotated from a pull hole drilled in the front panel of the door. , the puller and the latch body,
By interlocking with the interlocking shaft, the latch body is configured to disengage from the furniture body.

[The problem that the idea aims to solve]

However, in the conventional structure in which the door is provided with a latch body, when the door is opened and closed, the kick-in locking claw part of the latch body moves together with the door, so the kick-in locking claw part is intrusive. There was a high risk of being injured by touching it, or of objects being kicked in and getting caught in the locking claw, which posed a safety problem.

Also, if a latch body is provided on the door as in the past,
Means for rotatably supporting the latch and operating means for disengaging the latch from the furniture body must be provided within the door cavity. Because of this, the door had to be made thicker, which caused the problem of increased weight of the door.

Furthermore, as a means for disengaging the latch body from the engaging portion of the furniture body, the latch body is rotated via a pull or an interlocking shaft rotatably provided in the cavity of the door. Another problem was that the structure of the operating means became extremely complicated, increasing manufacturing costs.

The object of the present invention is to provide a latch device that solves all of these problems such as safety when opening the door, increased weight of the door, and manufacturing cost.

[Means to solve the problem]

In order to achieve this purpose, the present invention is such that a door is rotatably attached to the opening edge of a furniture main body with an open front on one side of the right or left side, and when the door is closed, the lower end edge of the furniture body is opened. A cross section is formed such that there is a gap between the inner surface of the furniture body and the front plate of the base plate of the furniture body, and a vertical piece is bent downward at the front end of the horizontal piece at the front end of the base plate of the furniture body. L
The horizontal piece of the latch body made of a metal plate in the shape of a letter protrudes forward through a hole drilled in the front plate of the main plate from the blank space of the main plate, and the downward vertical piece extends between the front plate of the main plate and the inner surface of the door. The horizontal piece of the latch body is arranged so as to extend downward from the lower end surface of the door from the gap between A piece is pivoted to move downward under the weight of the latch body and upward against the weight of the latch body; A kick-in locking claw part is cut and raised to fit into and engage with an engaging part formed on the inner surface of the latch body, and a lower end of the downward vertical piece of the latch body extends toward the front of the furniture main body. The operating piece is formed by bending.

[Functions and effects of the idea]

In this way, when the latch body is provided on the furniture body,
Even if the kick-in locking pawl on the latch body is exposed from the furniture body, its position remains unchanged and does not move, so if a person touches the kick-in locking pawl on the latch body, injury may occur. It is possible to improve safety when opening the door by preventing or reducing accidents such as kick-in or objects getting caught in the kick-in locking claw part.

In addition, it is sufficient that the door has an engaging portion into which the kick-in locking pawl of the latch body fits and engages. Since the thickness of the door is sufficient, the thickness of the door can be made significantly smaller than that of the conventional door, and the weight of the door can be reduced.

Furthermore, since the latch body is disengaged from the further engaging portion by directly rotating the latch body, the structure for rotating the latch body can be significantly simplified. Moreover, since the latch body can be easily manufactured by sheet metal processing of a single metal plate, the processing cost can be reduced.

Also, place the downward vertical piece of the latch body between the front plate of the main plate of the furniture body and the inner surface of the door.
Since the latch body is arranged so as to extend downward from the gap, there is no need to form a notch in the base plate or the door to enable the latch body to be disengaged from the door, which reduces the labor of processing the furniture. Furthermore, since the downward vertical piece of the latch body is made of metal plate and can be formed thinly, the space provided between the front plate of the main plate and the inner surface of the door can be extremely small. Since the items stored in the furniture body will not fall out during this time, the storage function of the furniture will not be impaired.

In this way, the structure for rotating the latch body can be made extremely simple, the latch body can be easily processed, and a special structure is provided on the main plate or door for rotating the latch body. The synergistic effect with the absence of the need for processing means that the manufacturing costs of the latch device can be significantly reduced without compromising the furniture storage function.

In addition, since the latch body is directly rotated by an operating piece provided integrally therewith, it is necessary to disengage the latch body from the door, in other words, to disengage the latch body from the door.
This means that the door can be reliably unlocked from the furniture body.

Therefore, according to the present invention, it is possible to reliably improve safety when the door is open, and also to reduce the weight of the door.
Moreover, although the latch device is capable of reliably opening the door, it has the effect of significantly reducing manufacturing costs without damaging the furniture storage mechanism.
