[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail mounting device for a multistage pull-out case.

[0002]

2. Description of the Related Art Conventionally, as a device for mounting a rail integrally formed of a synthetic resin material on the inner side surface of a case for organizing slips, catalogs, etc., a rail mounting hole paired in the front and rear direction on the inner side surface of the case body is used. The rail is made of synthetic resin having an L-shaped cross section, and engaging pieces are fitted in the mounting holes on the front and rear of the rail vertical piece, and engaging pieces are provided to hold the edge of the hole by shifting in the front-back direction. The stopper piece is provided so as to face the engaging piece of the above and fit into the above-mentioned mounting hole and regulate the movement of the rail in the front-rear direction. (For example, Jitsuko Sho 62-12
No. 336 publication)

In this case, since the stopper piece is opposed to the engaging piece and protrudes in the protruding direction of the engaging piece, that is, in the outward direction (the case body side), once the rail is attached to the inner surface of the case, the stopper piece and the engaging piece are engaged. All the pieces are hidden. Therefore, the number of trays to be mounted in the case,
When it is necessary to change the mounting position of the rail to change the size, the rail cannot be removed, and if necessary,
I could not change the mounting position of the tray at all.

[Problems to be Solved by the Invention] The present invention aims to solve the above problems. That is, it is an object of the present invention to provide a rail mounting device having a simple structure and facilitating rail removal work.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] A locking claw that engages with a plurality of mounting holes formed on the inner surface of the case is oriented in the front-rear direction.
While being formed integrally with the substrate, a hole through which the locking claw faces is formed in the substrate where the locking claw is located, and at the same time, an engaging protrusion is formed on the inner surface of at least one tip of the locking claw, An engagement hole is formed on the inner surface of the case corresponding to the engagement protrusion.

FIG. 6 shows a perspective view of a drawer and a rail in a separated state. Reference numeral 1 indicates a rail, and reference numeral 2 indicates a drawer.

As shown in FIGS. 1 to 5, the rail 1 includes a substrate 11 that abuts against the inner surface 5 of the case in a mounted state, and a substrate 11
, A plurality of locking claws 3 protruding laterally in an L shape, a supporting projection 4 for supporting the drawer 2, and a front end portion of the supporting projection 4 at a predetermined position in the front-rear direction. Stopper protrusions 41 formed at predetermined positions with a certain interval are integrally formed of a synthetic resin material. Reference numeral 6 indicates a hole formed at the position where the locking claw 3 is located at the time of rail molding. Further, reference numeral 12 ... Represents a reinforcing rib.

Each of the locking claws 3 has a guide projection 31 having a tip portion slightly outwardly projected, and a base portion 32 with which an end edge of a mounting hole 51, which will be described later, abuts in a mounted state. The locking claw 3 has a notch recess 33 on the side of the base 32 to provide further elasticity, and an engaging projection 30 is formed on the inner surface of the guide projection 31 on the side of the base 32 to project toward the hole 6. There is.

The support ridges 4 have a predetermined space between the upper and lower sides.
It is composed of two protrusions, and the extraction inclined portion 4 is inclined to the front side of the lower protrusion and is inclined upward as it goes forward.
0 is formed.

On the inner surface 5 of the case, there are a plurality of mounting holes 51, ...
An engaging hole 50 with which the engaging protrusion 30 engages is formed in front of the. The front-rear vertical width of the mounting hole 51 is formed to be substantially equal to the front-rear vertical width of the locking claw 3.

The drawer 2 is composed of a front plate 21 and a body portion 22, and is formed in the front-rear direction of the left and right side portions 23, 23 of the body portion 22 and into which the support projection 4 of the rail 1 fits. 24, and a stopper 25 formed on the lower portion of the rear end of the drawer recess 24 and protruding outward.

The drawer 2 is supported by the rail 1 attached to the inner surface 5 of the case so that it can move in and out forward and backward. When the drawer 2 is drawn out forward, the stopper 25 collides with the stopper projection 41 and the drawer 2 Will stop. When pulling out the drawer 2 from the case in this state, the front plate 21 is lifted upward, and the stopper 25 is pulled out forward while maintaining the state of being positioned above the stopper protrusion 41.

Further, when the drawer 2 is mounted, the drawer 25 is fitted before the stopper 25 collides with the front surface of the stopper projection 41 with the rear end of the drawer recess 24 fitted to the front end of the support projection 4. , The front plate 21 is lifted up to pass the stopper protrusion 41, and the drawer 2 is pushed in. Then, the drawer 2 is stopped in a state where the rear surfaces of the left and right end portions of the front plate 21 collide with the front surface of the case.

On the other hand, when mounting the rail 1 on the inner side surface 5 of the case, first move the locking claws 3 of the rail 1 from the inside to the mounting holes 51, and then move the rail 1 forward. Then, the locking claw 3 is locked to the front end edge of the mounting hole 51. At this time, the engaging projection 30 of the locking claw 3 at the center of the engaging hole 5
0 to prevent the rail 1 from moving backwards.

In addition, since the mounting position of the drawer 2 is changed in the vertical direction, when the rail 1 is removed from the inner side surface 5 of the case, after the drawer 2 is pulled out, an engaging protrusion facing the extraction hole 6 with the tip of a screwdriver or the like. The rail 1 is pushed backward while maintaining the state in which 30 is deviated from the engaging hole 50,
Detach the locking claws 3 further and remove them.

In the embodiment, three locking claws 3 are formed in the front direction and the front direction, but may be formed in the rear direction.
Further, the number of locking claws 3 may be plural. Further, the formation position of the engagement protrusion 30 is not limited to the specific locking claw 3.

[0017]

As described above, according to the present invention, the locking claws that engage with the plurality of mounting holes formed on the inner surface of the case are formed integrally with the substrate in the front-rear direction, and the locking claws are formed. The board located is formed with a hole through which the locking claw faces, and at the same time, an engaging projection is formed on the inner surface of at least one tip of the locking claw and is engaged with the inner surface of the case corresponding to the engaging projection. Since the dowel hole is formed, when the rail is attached to the inner surface of the case, when the drawer is pulled out, the engaging protrusion that engages with the engaging hole can be visually confirmed from the hole of the rail. Further, since the engaging projections are engaged from the inside of the inner side surface of the case toward the outside (board side of the rail), the engaging attitude can be easily released with a dry door or the like. In this way, the present invention has a simple structure, and the work of removing the rail is very easy.
