本考案は、キヤビネツト等における抽斗のラツ

A latch device for a drawer in a cabinet, etc. usually has a horizontal shaft pivotably supported on the inner surface of a head plate constituting the front face of the drawer, which can be rotated through a pull member from a pull hole in the front face of the drawer. A vertical and longitudinal latch rod with a latch claw that engages and disengages from the main body is rotatably supported on the edge so as to be rotatable around its axis, and the latch rod is rotated in conjunction with the rotation of the horizontal shaft. are related so that they can be rotated,
Conventionally, when supporting the latch rod on the inner surface of the end plate, a support piece was welded to the inner surface of the end plate, which made machining of the end plate complicated and also troublesome to assemble the drawer. Therefore, as a prior art,
In Publication No. 22858, the latch pawl and the latch rod are assembled in advance into a roughly half-cylindrical fitting made of plastic, and this fitting can be attached to the inner surface of the end plate, thereby reducing the assembly work of the latch device. We propose to simplify the .

作業工程が減少しない。
However, according to the above-mentioned prior art, when attempting to attach the latch rod to the mounting tool on the inner surface of the head panel, the mounting tool must be installed with the outer panel of the head panel removed. , the assembly work process is not reduced.

共に、ばねの一端は抽斗側板に接当させているに
過ぎないので抽斗の押し込みに際しての衝撃等で
脱落する虞があつた。 In addition, the drawer latch device requires a spring to maintain the engagement posture of the latch pawl with the main body when the drawer is stored, but in the case of the prior art, the attachment device includes only the latch rod and the latch pawl. Since the spring is installed between the latch pawl and the drawer side plate after the drawer is assembled, a separate process is required to assemble the spring, which does not necessarily simplify the assembly process. In addition, since one end of the spring was only in contact with the side plate of the drawer, there was a risk that the spring would fall off due to impact etc. when the drawer was pushed in.

ていなかつた。 Furthermore, although Japanese Utility Model Application Publication No. 59-51965 discloses a structure in which a torsion spring is incorporated into a fixture in which a latch rod and a latch pawl are pre-assembled, the latch rod is supported horizontally, In addition, the attachment is fixed to the end plate of the drawer with screws,
The latch claw attached to the latch rod is on the inner surface (back side) of the head plate.
The structure of the part protruding from the side toward the inner surface of the cabinet body was unclear, making it impossible to simplify the assembly process, and furthermore, the torsion spring did not play the role of a seat for the latch pawl.

Therefore, in this invention, the main body 2 of the cabinet etc.
A horizontal shaft 7, which can be rotated through a pull hole 6 through a pull member 8 on the front surface of the drawer, is supported on the end plate 3 of the drawer, which is provided so as to be movable back and forth, and is driven by the horizontal shaft 7. A rotatable vertical latch rod 11 and a latch pawl 12 that rotates integrally with the latch rod 11 to engage and disengage from the locking portion 14 of the main body 2.
In a drawer latch device comprising a support member 9 rotatably supporting the inner surface of the end plate 3 and the end plate 3,
A space is formed by a folded piece 3' whose side edge is bent into a U-shaped cross section, and the support member 9 to be inserted into the space is inserted between a portion along the inner surface of the mirror plate 3 and the opening of the folded piece 3'. A side plate 9a that covers the side, and an upper plate 9 that rotatably supports the upper and lower parts of the latch rod 11.
b, and a lower surface plate 9c, the side plate 9a is provided with a plurality of engagement claws 9d that are non-removably engaged with the engagement holes 10 provided in the folded piece 3', and the latch rod 11 The latch pawl 12 is fitted into the latch pawl 12 so as to rotate integrally with the latch pawl 12, and the coil portion of the torsion spring 13 is inserted between the lower surface of the latch pawl 12 and the upper surface of the lower plate 9c of the support member 9. The latch pawl 12 is biased toward the locking portion 14 by a torsion spring 13 fitted in the torsion spring 11;
6 is formed so as to communicate with the opening edge of the folded piece 3'.

In this way, the latch rod 11, latch pawl 12, and torsion spring 13 are assembled into the support member 9 in advance, and the support member 9 is inserted through the opening between the inner surface of the end plate 3 and the folded piece 3'. When inserted into the space, the side plate 9a of the support member 9 will cover the inner surface of the end plate 3 and the opening side of the folded piece 3', and the support member 9 will fit tightly into the space. Then, a plurality of engaging claws 9d provided on the side plate 9a are connected to a locking hole 10 provided on the folded piece 3'.
The latch claw 12
Since the cutout groove 16 for inserting the support member 9 is formed so as to communicate with the opening edge of the folded piece 3', the work of attaching the support member 9 can be carried out with one touch, and unlike the prior art described above, the notch groove 16 is formed so as to communicate with the opening edge of the folded piece 3'. This eliminates the need for a separate process to mount the spring after assembly, which simplifies the assembly process and improves work efficiency.The torsion spring can also be attached to the support member without easily falling off. play.

大部分は切り抜いている。 Reference numeral 9 designates a support member into which a latch rod 11, a latch pawl 12, and a spring 13, which will be described in detail later, are incorporated. It is inserted into a space formed by a folded piece 3' which is folded back from the side edge in a U-shape in a plan cross-sectional view. When attaching the support member 9 to the end plate 3, the side plate 9
A pair of upper and lower engaging claws 9d that can be wrapped around and deformed in the front-rear direction are horizontally protruded from the front end of the mirror plate 3, while both of the engaging claws 9 are provided on the folded back piece 3' of the mirror plate 3.
A locking hole 10 is formed in each portion corresponding to d, and the engaging claw 9d is engaged with the locking hole 10, thereby locking the body so that it cannot fall off. Of course, the means for attaching the support member 9 is not limited to the embodiment, and other means may be used. Note that most of the back surface of the support member is cut out.

係止部１４に対して係脱するように構成する。 Then, the top plate 9b and the bottom plate 9 of the support member 9
By drilling support holes 9b' and 9c' in c, the vertically elongated latch rod 11, which is integrally fitted with the latch claw 12 extending along the outer surface of the side plate 4 of the drawer 1, can be moved around its axis. As the latch rod 11 rotates, the latch pawl 1
The two hole-like engaging portions 12c are configured to engage and disengage from a locking portion 14 provided inwardly protruding from the main body 2.

立作業が至極簡単となる。 In this case, the support hole 9 of the upper surface plate 9b of the support member
A groove 9b'' for passing the fin piece 11b of the latch rod 11 is formed in b'. The engaging piece 9a is inserted into the hollow part of the side edge of the end plate 3 while following the inner surface, and the engaging piece 9a is engaged with the locking hole 10 formed in the folded piece 3', while the latch claw 12 portion is inserted into the folded piece 3'. The contact part 11 of the latch rod 11 is inserted into the notch groove 16 of the
a is engaged with the contact portion 7a of the horizontal shaft 7 that has been provided in advance. In this way, the support member 9 can be attached to the inner surface of the end plate 3 with a single touch, making the assembly work of the latch device extremely simple.
