The latch lever 83 is made of a synthetic resin, is a horizontally long rectangular plate having a predetermined thickness, and has the same cross-sectional shape as the above-described square portion 81b of the latch lever shaft 81 in the vertical direction. A bearing portion 83a having engaging holes 83b and 83b that penetrate therethrough, and a latch hole 83c that penetrates in the thickness direction at a tip portion opposite to the bearing portion 83a are provided, and the bearing portion 83a leaves an upper surface and a lower surface, A recess 83d is formed in which an intermediate portion is cut out.
The base material forming the lower surface of the bearing portion 83a is provided with a fitting hole 83e penetrating downward from the concave portion 83d side in the vicinity of an intermediate portion between the engaging hole 83b and the latch hole 83c.

The latch spring 84 is a torsion coil spring, and includes a central coil portion 84a, a first leg portion 84b extending linearly from one of both ends of the spring wire forming the coil portion 84a, and the other end portion. The first leg portion 84b and the second leg portion 84c extend radially from the coil portion so as to form a substantially V shape.
A fitting portion 84e bent 90 degrees downward is formed at the tip of the first leg portion 84b.
In addition, a push-in portion 84f bent toward the outside of the V-shape is formed at the distal end portion of the second leg portion 84c.

As for the assembly method of the latch lever body 8, first, the fitting portion 84e of the latch spring 84 is inserted into the fitting hole 83e of the latch lever 83 from the concave portion 83d side of the latch lever 83, and the coil portion 84a side of the latch spring 84 is latched. The lever 83 is assembled so as to be positioned on the concave portion 83d side. In this state, since the fitting portion 84e of the latch spring 84 is inserted into the fitting hole 83e of the latch lever 83 and the latch spring 84 is held, the latch spring 84 is not accidentally dropped.

Next, the bearing 83a side of the latch lever 83 is inserted into the latch support member 82 together with the coil portion 84a side of the latch spring 84 from the opening of the latch support member rear surface 82b. At this time, the side surface of the second leg portion 84 c of the latch spring 84 abuts on the inner wall of the latch support member 82, and the first leg portion 84 b side is fixed by the fitting hole 83 e of the latch lever 83. It is inserted into the latch support member 82 so that the distance between the tips of the mold is narrowed.
That is, the latch spring 84 has a repulsive force in a direction in which the interval between the V-shaped tips is widened when the latch spring 84 is inserted into the latch support member 82.

In this state, the tip of the rotation shaft 81 a of the latch lever shaft 81 is inserted from the rotation shaft hole 821 on the upper surface of the latch support member 82.
Next, the tip of the rotation shaft 81 a is inserted into the upper engagement hole 83 b of the latch lever 83.
Next, the tip of the rotation shaft 81a is inserted into the hole of the coil portion 84a of the latch spring 84. At this time, the latch spring 84 tries to come out of the latch support member rear surface 82b by the repulsive force of the latch spring 84. Yes. Therefore, in order to insert the tip end of the rotation shaft 81a into the coil portion 84a of the latch spring 84, the finger portion 84f of the latch spring 84 is pushed toward the latch support member 82 side with a finger while turning the coil portion 84a of the latch spring 84. The tip of the moving shaft 81a is inserted. Then, the tip of the rotation shaft 81a is inserted into the engagement hole 83b on the lower side of the latch lever 83, and finally inserted into the rotation shaft hole 821 on the lower surface of the latch support member 82, whereby the latch lever body 8 is assembled. It is done.
Even if the pushing portion 84f of the latch spring 84 is not provided, there is no change in the function of the latch lever body 8 in the assembled state. However, if the pushing portion 84f of the latch spring 84 is not provided, the latch spring 84 is connected to the latch support member 82 side. Since the portion to be pushed becomes the end portion of the spring wire material when being pushed into, the pushing operator may be injured. Therefore, it is safer to provide the pushing portion 84f and push the side surface of the spring wire of the pushing portion 84f.
There is a method of using elastically deformable resin or rubber instead of the latch spring.

Since the cross-sectional shape of the engagement hole 83b of the latch lever 83 and the square portion 81b of the latch lever shaft 81 is the same, the latch lever 83 is assembled to the latch lever shaft 81 in a non-rotating state. Therefore, when the latch lever shaft 81 rotates, the latch lever 83 also rotates.
Further, since the second leg 84c of the latch spring 84 is in contact with the inner wall of the latch support member 82 and the first leg 84b is fitted to the latch lever 83, the latch spring 84 is relieved by the repulsive force. The lever 83 is biased so as to rotate in a direction in which the interval between the V-shaped tips of the latch spring 84 is widened with the latch lever shaft 81 as a rotation axis.
The latch lever shaft 81 is assembled so that the interlocking passive rod 81c intersects the longitudinal direction of the latch lever 83 in the direction opposite to the direction in which the latch lever 83 is urged.

The latch lever body 8 is attached to the front body 4 as follows.
The latch lever body 8 is mounted on one side of notches 423 and 423 provided on both sides of the back plate 42 from the front of the back plate 42, and only a separately provided latch support member 82 is provided on the other side. Is installed.
At this time, the latch lever 83 of the latch lever body 8 is mounted so that the urging direction of the latch lever 83 is directed toward the outside of the back plate 42, and the interlocking passive rod 81 c is mounted so as to be directed to the inside of the back plate 42.
Thus, in a state where the latch lever body 8 is mounted on the back plate 42, the rear surface of the interlocking passive rod 81 c comes into contact with the front surface of the interlocking biasing rod 72 b of the operation lever body 7.

A method of attaching the latch lever body 8 to the back plate 42 will be described in detail.
As shown in FIG. 14, first, the latch lever body 8, the latch lever 83 of the latch lever body 8 protrudes backward, and the biasing direction of the latch lever 83 is the back plate 42. Arrange in the direction of the outside.
Next, as shown in FIG. 15, the latch lever body 8 is inserted into the notch 423 of the back plate 42 on the latch lever 83 biasing direction side from the inside of the back plate 42 to the outside.

The height of the notch 423 is large enough to allow the latch support member main body 821 to be inserted. The upper and lower ends of the notch 423 abut on the upper and lower surfaces of the latch support member 82, thereby supporting the latch. The dimension is set so that the member 82 does not move up and down.
First insertion holes 424 and 424 through which the outer protrusions 82f and 82f of the latch support member 82 and the sandwiching protrusions 82k and 82k can be inserted are provided on the upper and lower parts of the front end of the notch 423, and further, the notch 423 is provided. A second insertion hole 425 into which the front protrusion piece 82h of the latch support member 82 can be inserted is provided at the front end portion of the first support member 82.

Then, as shown in FIG. 16, the outer protrusions 82f and 82f of the latch lever body 8 and the sandwiching protrusions 82k and 82k are inserted into the first insertion holes 424 and 424, and the front protrusion 82h is inserted into the second insertion hole. The latch lever body 8 is partially inserted into the hole 425 and protrudes outward from the notch 423. At this time, the outer side surface of the inner projecting piece 82e is in contact with the vicinity of the upper and lower edges of the notch 423 of the second side surfaces 42f and 42f, and the latch lever body 8 is regulated so as not to protrude outward from the corresponding contact state. The

Next, as shown in FIG. 17, the latch lever body 8 is pushed rearward, and the inner projecting piece 82e is brought into contact with the vicinity of the upper and lower edges of the notched portion 423 of the second rear surfaces 42e and 42e. The latch lever body 8 is regulated so as not to protrude rearward from the contacted state.
In this state, the latch support member rear surface 82b protrudes from the second rear surfaces 42e, 42e.
Next, when the latch lever body 8 is pushed inward (on the second side face 42f side), the latch lever body 8 rotates around the contact surface between the inner protruding piece 82e and the second rear face 42e. Then, the sandwiching projection piece 82k passes through the notch 423 while being elastically deformed, and the outer projection piece 82f contacts the second side surface 42f. Furthermore, the inner surface side 82m of the latch support member 82 contacts the notch portion inner end portion 426. In addition, the rear protrusion 82i comes into contact with the second rear surfaces 42e and 42e (FIG. 18).
At this time, the base material on the second side face 42f side is sandwiched between the outer protruding piece 82f and the holding protruding piece 82k. Therefore, the latch lever body 8 is temporarily held by the notch 423.

Next, as shown in FIG. 20, the front surface plate 41 is attached from the front of the back surface plate 42. At this time, since the latch lever body 8 is temporarily held in the cutout portion 423 by the outer protruding piece 82f and the holding protruding piece 82k, the assembly operator needs to hold the latch lever body 8 by hand. Absent.
When the surface plate 41 is attached, the front protrusions 82 h are inserted into the locking holes 411 provided on the back side of the surface plate 41, and the front pressing surface 82 g is pressed on the back side of the surface plate 41.
Note that the locking hole 411 is set to a size such that the front-side protruding piece 82h is included, and does not rattle after insertion.
Further, the first insertion holes 424 and 424 and the second insertion hole 425 of the notch 423 are positioned inside the surface plate 41 and are hidden so as not to be seen from the outside, and the front pressing surface of the latch support member 82 82g is pressed behind the surface plate 41, so that the outer protrusions 82f and 82f of the latch support member 82 and the sandwiching protrusions 82k and 82k pass through the first insertion holes 424 and 424 and the second insertion hole 425. Absent.

The side surfaces 82j and 82j outside the latch support members 82 and 82 have dimensions corresponding to the contact between the inner surfaces 2b and 2b of the cabinet body 2 with the drawer 3 attached to the cabinet body 2 and the drawer 3 closed. It protrudes from the second side surface 42f.
Therefore, the drawer 3 is prevented from swinging in the left-right direction in the closed state.

By providing the latch support member 82 with the left and right steadying function of the drawer 3, it is possible to reduce the types of parts, reduce the number of assembling steps, and reduce the management cost.
Furthermore, by using the latch support member 82 as a steady rest on the side where the latch lever is not provided, the notches 423 and 423 provided on both side surfaces of the back plate 42 can be processed in the same way on the left and right. It leads to shortening of time. Of course, since the latch lever body 8 can be interchanged between the left and right sides, there is no need to make a member with each of the right hand and left hand, and it is possible to make the right and left common.

Even if an unexpected force is applied to the latch lever body 8 mounted in this way from any of the top, bottom, front, back, left and right directions, the latch lever body 8 is securely fixed without being moved carelessly.
For example, when any force in the vertical direction is applied to the latch lever body 8, the upper end or lower end of the notch 423 comes into contact with the upper or lower surface of the latch support member 82, and the movement is restricted. Body 8 does not move.
When a force in the inner direction is applied to the latch lever body 8, the outer protrusion 82 e comes into contact with the vicinity of the upper and lower edges of the notch 423 of the second side surfaces 42 f and 42 f, and the inner surface 82 m is the inner end of the notch. The latch lever body 8 does not move because it abuts against the portion 426 and the front protrusion 82h abuts against the inner surface of the locking hole 411 and the movement is restricted.
When a force in the outward direction is applied to the latch lever body 8, the front protruding piece 82 h abuts against the inner surface of the locking hole 411 and the movement is restricted, so the latch lever body 8 does not move.
When a rearward force is applied to the latch lever body 8, the inner projecting piece 82e abuts on the vicinity of the upper and lower edges of the notch 423 of the second rear surfaces 42e, 42e, and the movement is restricted. It does n’t move.
When a force in the front direction is applied to the latch lever body 8, the front pressing surface 82g comes into contact with the back surface side of the surface plate 41 constituting the surface of the front body 4, and the rear protrusion piece 82i cuts the second rear surface 42e. The latch lever body 8 does not move because the movement is restricted by contacting the vicinity of the edge of the notch 423.

In this way, the latch lever body 8 is not only securely mounted, but also can be assembled by human hands without using screws and without using tools, so it is easy to assemble and assemble. It also leads to time savings.

The interlocking device 9 is formed by the interlocking biasing bar 72b of the operating lever body 7 and the interlocking biasing bar 72b of the operating lever shaft 72. As described above, the interlocking biasing bar 72b of the operating lever body 7 and the control lever Since the interlocking urging bar 72b of the shaft 72 is in contact, when the operating portion 71b of the operating lever body 7 is raised upward, the operating lever shaft 72 rotates and the interlocking urging bar 72b rotates forward. . At this time, the interlocking biasing rod 72b pushes the interlocking passive rod 81c from the rear surface, so that the interlocking passive rod 81c also rotates forward. When the interlocking passive rod 81c rotates forward, the latch lever 83 rotates toward the inside of the drawer.
The movement of the operation unit 71 b is transmitted to the latch lever 83 by the action of the interlocking device 9.

As shown in FIG. 6, the latch support member 82 can also be used as a latch support member that holds the intermediate portion in the height direction of the vertical portion 81a.

As shown in FIG. 20, when the latch lever body 8 is assembled in the drawer 3 that is shallow in the vertical direction, the latch rotating shaft 81 is incorporated in the upside down direction unlike the above, and the vertical portion 81a is also short. .

As described above, since the present invention relates to a drawer latch device in a cabinet, it can be widely used in cabinets having drawers such as a fixed cabinet and a movable cabinet.
