Description of the Related Art In general, a latch device for a drawer or a door is provided with an engaging portion such as a nail or a hole on the inner surface of a furniture body, while a latch claw corresponding to the engaging portion of the main body is provided on the drawer or the door. It is provided so as to be freely rotatable horizontally, and a spring urges the latch claw to engage with the engagement portion so as to be selfish.Furthermore, when the pull provided on the door or the front of the door is pulled, the latch claw is disengaged from the engagement portion. It is configured to interlock via an interlocking member so as to be separated.

に当てた構成が記載されている。[0003] Japanese Patent Publication No. 59-11031 discloses a door latch device in which a latch member (driving body) formed of a synthetic resin into a parallelogram in a plan view is provided on the back surface of the door. And a latching claw that engages with an engaging portion of the main body on a side of the latch member that faces the main body. Further, there is described a configuration in which an operating rod of a puller is slidably fitted into a door, and a flange provided on the operating rod is brought into contact with a rear end surface of a latch member.

部から離脱してラッチが解除される。In this case, the hole in which the operating rod is fitted in the latch member is formed as a long hole extending in the left-right direction. Therefore, when the puller is pulled, the latch member collapses and deforms as a whole in a flat shape. The rear part of the latch member slides away from the main body, whereby the locking claw is disengaged from the engaging portion of the main body, and the latch is released.

て組立の手間を軽減できる利点がある。According to the configuration disclosed in Japanese Patent Publication No. 59-11031, the locking claw is returned to a state where it can be engaged with the engaging portion by utilizing the restoring force of the latch member itself. Therefore, there is an advantage that a spring is not required, and the number of members is reduced correspondingly, so that the assembling work can be reduced.

った。However, according to the configuration of this publication, when the latch member is deformed and the locking claw is disengaged from the engaging portion, the rear portion of the latch member rubs against the flange of the operating rod. The resistance at the time of deformation is large, and therefore, there is a possibility that the set of the latch member is fast and the durability is low.

And the tip of the spring piece 19 abuts against the base.
And a puller 5 provided on the drawer 1 or the door and the connecting portion.
And 12 are interlockingly connected such that when the puller 5 is pulled, the locking portion 15 is disengaged from the engaging portion 8 so that the arm 11 rotates .

Therefore, the latch is automatically released by the drawer withdrawing operation or the door opening operation. When the hand is released from the handle, the arm returns to the original position by the elastic restoring force, and the handle also returns to the original position.

するためである。The guide shaft 14 protrudes from the front surface of the end plate 2 by a small dimension in the retracted state.
Is fixed to the end of the puller 5 with a screw 23 inserted from behind. Therefore, the guide shaft 14 can be slid forward and backward by a fixed stroke L. As shown in FIG. 3, a plurality of (four) ridges 24 are formed on the outer periphery of the guide shaft 14. This is to reduce the friction between the guide shaft 14 and the cylindrical portion 10a.

不能に保持される。As shown in FIG. 2, the arm 11 is covered with a cover 25 (the cover 25 is omitted in FIG. 1). The cover 25 is formed in a convex shape when viewed from the side, and is opened toward the side plate 6 of the main body to allow the arm 11 to rotate. In addition, the upper and lower edges of the cover 25 are bent inward, and the upper and lower bent pieces 25a are formed on the upper and lower edges of the base 10.
Fitted in 26. Therefore, the cover 25 is held so that it cannot be pulled backward.

なわちラッチが解除されて）抽斗１が引き出される。On the other hand, if the hand is put on the puller 5 in the closed state and pulled forward, the arm 11 is connected via the connecting portion 12 in conjunction with the guide shaft 14 sliding forward as shown in FIG. As a result, the engaging claw 15 is disengaged from the engaging claw 8 (that is, the latch is released), and the drawer 1 is pulled out.

And the locking claw 15 returns to a state where it can be engaged with the engaging claw 8. Therefore, when the drawer 1 is pushed into the main body by placing a hand on an appropriate portion on the front surface of the end plate 2, the locking claw 15 is engaged by so-called recess engagement in which the arm 11 rotates once and then returns. It engages with the dowel 8.

てしまうことを防止できる利点がある。When the V-groove-shaped thin portion 21 is formed in the connecting portion 12 as in the embodiment, the locking claw 15 is pushed when the drawer 1 is pushed in.
When the arm 11 is rotated so as to separate from the engaging claw 8 during the crimping engagement, the connecting portion 12 bends in a V-shape as shown by a dashed line in FIG. For this reason, there is an advantage that it is possible to prevent the guide shaft 14 from sliding forward when the drawer 1 is pushed in and the pull tab 5 from moving forward.
【００３２】薄肉部21は複数個設けても良い。また、接

It is manufactured in a developed state by injection molding using a pair of molds 30 and 31 that can be in close contact with and separated from each other, and injecting a molten synthetic resin into a cavity formed in the mating surface of the two molds. Then, the guide shaft 14 is fitted into the cylindrical portion 10a of the base 10.
