Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door latching device for furniture and the like. The present invention relates to a sliding door latch device in furniture or the like in which a sliding door can be engaged with a main body side plate so that a stored item does not slide out and pop out.

[0002]

2. Description of the Related Art In the case of conventional sliding door type furniture, there is a latch mechanism which is not generally employed, unlike an opening door.

[0003]

However, in the above-mentioned prior art, there is a danger that the sliding door will slide and the stored items will pop out in the event of an earthquake or the like.

In view of this situation, the present invention utilizes a pulling part of a sliding door to provide a latch device so as to be substantially flush with each other, and the latch of the latch device and the latch provided on the body side plate side. It is an object of the present invention to provide a latching device for a sliding door in furniture or the like that can be engaged and disengaged with a hanging tool.

[0005]

In order to solve the above-mentioned problems, the present invention provides a latching device for a sliding door in furniture or the like, in which the latching device is provided on the pulling part of the sliding door in a substantially flush state. The latch device has a structure in which a latch lever rotatably supported is provided, and the latch can be engaged with and disengaged from a latch hook provided on a furniture main body side plate reinforcing portion by rotating the latch lever. Adopted.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a latch hook is provided on a furniture body side plate reinforcing portion corresponding to a pulling portion of a sliding door,
The latch mechanism is provided with a latch mechanism which is substantially flush with the recess of the pull tab so that the protrusion does not exist so that the latch mechanism can be engaged and disengaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. Referring to FIGS. 1 to 3, the sliding door latch device of the present invention will be described in detail.
It is provided on the pulling part 3 of the sliding door 2 shown in FIG.

First, FIG. 1 is a schematic front view of a steel sliding book store which is an example of furniture. 1 is a main body of the store, 2 is a left and right sliding door, 3 is a pull part, and 4 is publicly known. Is a lock.

Next, the latch device 5 of the present invention will be described in detail with reference to FIGS. First, the main body 1
The latch hook 9 is attached to the concave portion 8 of the reinforcing portion 7 formed on the front side of the side plate 6. This attachment is performed by using the locking projection 10 provided on the back surface side of the latch hook 9 and fixing it to the attachment hole 11 of the concave portion 8 formed in the furniture main body side plate reinforcing portion 7.

As shown in FIG. 2, a hole 12 for attaching the pulling handle 3 is formed in the sliding door 2 so as to correspond to the latch hook 9, and the hole 12 is made of synthetic resin or the like. The hand 3 is engaged, which engages the engaging projection 14 with the end of the hole 12 and further presses the elastic locking piece 13 at the other end to push it in and push the pulling hand 3 into the hole. It is engaged and fixed to 12. In addition, a hole 21 is formed in the side end 20 of the sliding door 2.
Has been drilled. This hole 21 allows the latch hook 9 to be engaged with and disengaged from the latch 19.

Further, the latch shaft 1 is provided above and below the pull tab 3.
5 has a through hole 16 formed therein, and as can be understood from those shown in FIGS. 2 and 3, first, the latch shaft 15 is inserted into one of the through holes 16 of the pulling part 3, and the latch shaft 15 is further inserted. 1
5, a latch lever 17 is provided via a spring 18, and is inserted into the other insertion hole 16 to be attached to the pull tab 3. A latch 19 is integrally provided on the latch lever 17.

The latch 19 is provided so as to face the latch hook 9 so as to engage and disengage as described above. Further, an inclined protrusion 22 is formed on the latch 19 and the latch hook 9. Further, the latch lever 17 is elastically restrained by the spring 18 so as to be substantially flush with the pulling part 3, and when the latch lever 17 is pressed (as shown by the phantom line in FIG. 2), the latch 19 is attached to the spring 18. On the other hand, the sliding door 2 can be swung via the latch shaft 15 to be disengaged and the sliding door 2 can be slid and opened. When the sliding door 2 is closed, it is in the engaged state as shown by the solid line.
Contents do not pop out.

Next, the operation will be briefly described. As described above, although it was explained a little in the explanation of the configuration, it will be explained in detail with reference to FIG.
In this, each member is located as shown by the solid line. The inclined protrusion 22 of the latch 19 and the inclined protrusion 22 of the latch hook 9 provided in the concave portion 8 of the body side plate reinforcing portion 7 such as furniture are engaged and locked. The latch 19 being in the locked state means that the latch lever 17 of the latch device 5 provided on the latch shaft 15 fixing the latch 19 is parallel to the surface of the sliding door 2. Thus, the spring 18 is constantly biased.

In order to open the sliding door 2 from the closed state of the sliding door 2, the latch lever 17 is manually moved to the spring 1.
When it is rotated like the chain double-dashed line against 8, the latch 19
The slanted protrusion 22 is released from the slanted protrusion 22 of the latch hook 9 fixed to the concave portion 8 of the main body side plate reinforcing portion 7 and the sliding door 2 is slid. When the door is released from the latch lever 17 after the door is opened, the spring 19 returns the latch 19 and the latch lever 17 to the steady position (position indicated by the solid line).

After that, when the door is closed, the slanted projection 22 of the latch 19 collides with the slanted projection 22 of the latch hook 9 and temporarily turns against the spring 18 toward the position indicated by the chain double-dashed line. Further, when the door is pushed, the slanted projection 22 of the latch 19 and the slanted projection 22 of the latch hook 9 are engaged with each other to return to the position indicated by the solid line, and the locking is maintained by the elastic force of the spring 18.

By providing the latch device 5 on the pulling part 3 of the sliding door 2 as described above, a safe sliding door type storage box in which stored items do not pop out even in the event of an earthquake or the like. can get.

[0017]

According to the present invention, the following effects can be obtained based on the above configuration. (1) The sliding door is locked by the latch device even in the unlikely event of an earthquake such as a sliding door type furniture such as a storage or a library, so that the stored items do not pop out.
