Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention particularly relates to a drawer with a pen tray used as a center drawer of an office desk.

<Prior Art and Problems> Conventionally, a pen tray housing attached to a drawer has storage compartments shaped to accommodate various articles in the front, back, left and right directions.

In other words, since the cross-sectional shape is not the same in the left and right direction (width direction of the drawer), it is necessary to mold various pen tray casings with different lengths to match the width of the drawer, which increases costs. was.

[Purpose and structure of the present invention] The purpose of the present invention is to obtain a drawer with a pen tray that has a simple structure, can be manufactured at low cost, and allows pen tray housings of different width dimensions to be easily attached. The main parts include a fitting locking part formed at the upper front end of the drawer body and opening at the bottom, a drawer having a locking groove opening at the front side formed at the bottom part of the drawer body, and formed on the bottom plate. a support protrusion that protrudes downward; an engagement protrusion that protrudes downward behind the support protrusion and engages the locking groove from the front side; and a partition mounting groove formed on the upper inner surface of the front and rear plates. The pentray housing is approximately U-shaped in cross section and has a locking protrusion formed on the upper end of the front plate, and is formed by extrusion molding of a synthetic resin material, and a fitting protrusion that fits into the partition mounting recess is located on the front and rear of the upper end. It consists of a partition member formed on a surface.

After fitting the front plate 3 outward from the side of the back plate 7, the locking legs 52, 52 are locked in the locking holes 70, 70, and the side end caps 5, 5 are attached to the side end surfaces of the front plate 3. Attach.

Next, the locking protrusion 421 of the pen tray housing 4 is
The pentray housing 4 is rotated clockwise in FIG. 1 from below and slightly behind the fitting locking part 30 to lock it in the fitting locking part 30.

At the same time, the locking protrusion 412 moves into the locking groove 60.
At the same time, a projection 241 for preventing the pen tray housing from rising is provided on the upper surface of the projection on the outside of the partition mounting groove 422.
The rear lower end of the concealing protrusion 44 of the pen tray housing 4 is in contact with the partition plate holding portion 62 of the pen tray guide 6.
In other words, the pentray housing 4 is securely held on the drawer body 2 without wobbling.

Next, when installing the partition member 8, after positioning the partition member 8 with the fitting protrusions 81 and 82 facing in the left-right direction of the pen tray housing 4 inside the pen tray housing 4, 8, and then rotate the fitting protrusion 8.
1 and 82 are fitted into the partition attachment grooves 422 and 432.

In addition, the rear end protrusion of the partition plate 230 is fitted into the partition plate attachment hole 231 of the rear plate 23, and the front end protrusion is inserted from above the front partition plate attachment hole 621 to connect to the partition plate holding portion 62 of the pen tray guide 6. , a partition plate 230 is attached between the rear plates 23.

On the other hand, when removing the pen tray housing 4, push the lower end of the front plate 42 forward to release it from the engaging protrusion 412 and the locking groove 60, and then pull up the rear plate 43. Then, remove the pen tray housing 4 from the drawer main body 2.

[Effects] As described above, in this invention, the pen tray housing is formed by extrusion molding of synthetic resin material, so even if the width dimensions of the drawers are different, the pen tray housing can be made to the specified width. A pen tray housing of the desired length can be obtained by simply cutting, and a fitting locking part that opens downward is provided at the top of the front end of the drawer, and a locking groove that opens at the front side is formed on the bottom surface. On the other hand, since a locking protrusion is formed on the upper front end of the pentray housing and an engaging protrusion is formed on the bottom plate, the pentray housing can be attached to the drawer body by rotating the pentray housing. It can be installed extremely easily by moving it, and it is securely held without wobbling after installation.Furthermore, partition mounting grooves are formed on the pen tray housing and fitting protrusions are formed on the partition member. Since the partition mounting groove and the fitting protrusion are fitted together, the partition member can be securely held in the pen tray housing.
