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 formed by forming an engaging part at the opening edge of the furniture body, and by forming an engaging part at the opening edge of the furniture body, as described in, for example, Japanese Utility Model Application Publication No. 58-5567. is formed into a hollow shape, and a latch body is rotatably provided in the hollow portion at the periphery of the door, and includes a kick-in locking pawl portion that protrudes backward from the inner surface of the door, When the door is closed, the kick-in locking pawl of the latch body is pressed by a spring so that it rotates in the direction in which it engages with the engaging portion of the furniture body. The hollow part of the door is configured to automatically engage with the engaging part of the door, and furthermore, there is a pull in the hollow part of the door that can be rotated from a pull hole drilled in the front panel of the door. The latch body is configured to be disengaged from the furniture body by interlocking the pull handle and the latch body with an interlocking shaft.

[Problem to be solved by the invention] 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 pawl of the latch body protrudes backward from the inner surface of the door. In this state, the kick-in locking claw moves integrally with the door, so the kick-in locking claw may come into contact with someone and cause injury.
There was a high risk of objects kicking in and getting caught in the locking pawl, 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 body, operating means for disengaging the latch body from the furniture body, etc. must be provided in the hollow part of the door, and these means for supporting the latch body, operating means, etc. In order to provide this, the door had to be made thicker, which caused the problem of increased weight of the door.

Furthermore, when disengaging the latch body from the engagement part of the furniture body, it is necessary to use a puller rotatably provided in the hollow part of the door or an interlocking shaft for interlockingly connecting the latch body and the puller. Since the latch body is rotated through a member, the structure of the operating means becomes extremely complicated, resulting in an increase in 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 object, the present invention pivots a door to the opening edge of a furniture main body with an open front side so as to be rotatable on one side of the right or left side, and the inner surface of the periphery of the door is A latch body for the door is rotatably provided at the opening edge of the furniture body, and the front end of the latch body is configured to face the front plate of the opening edge and close the furniture body. A kick-in locking pawl portion is provided at the front end of the latch body, which protrudes forward from a hole drilled in the front plate of the opening edge of the main body, and fits into and engages with an engaging portion provided on the inner surface of the door. A kick-in locking pawl is provided at the front end of the latch body to bias the latch body in a direction in which the kick-in locking pawl portion engages with the engaging portion of the door. The operating part for rotating the latch body in the direction of disengaging from the engaging part is provided so as to extend toward the outside of the furniture main body from a region between the opening edge of the furniture main body and the peripheral edge of the door.

[Functions and effects of the idea]

In this way, when the latch body is provided on the furniture body,
When the door is installed, even if the kick-in locking pawl on the latch body is exposed from the furniture body, its position remains unchanged, so compared to the case where the latch body is installed on the door, the kick on the latch body will be easier. To improve safety when opening a door by preventing or reducing accidents in which a person is injured by touching a push-in locking claw or an object is caught in a push-in locking claw.

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 significantly reduced and the weight of the door can be reduced.

Furthermore, the latch body has an integrated operation part for disengaging the kick-in locking claw part of the latch body from the engagement part of the door, eliminating the need for the conventional interlocking shaft and puller. Therefore, the number of parts can be reduced and the structure can be made extremely simple.
Manufacturing costs can be reduced, and since the latch body is directly rotated, the latch body can be reliably disengaged from the furniture body.

Therefore, according to the present invention, there is provided a latch that can reliably improve safety when the door is open, can reduce the weight of the door, and can reliably perform the operation of disengaging the latch body from the door. This has the effect that the device can be provided at low cost.
