Description

[Detailed description of the invention] The present invention relates to the rear structure of an assembled drawer, and more specifically, in a drawer assembled with a front plate, side plate, and bottom plate, an L-shaped locking piece is bent inward from the rear end of the side plate. L-shaped bent pieces that fit inwardly into the grooves formed by the locking pieces on both ends of the rear plate are connected, and L-shaped locking pieces that can be fitted externally from above into the locking pieces of the side plates are formed on the upper end. It is made by connecting the locking pieces, and the bent piece of the rear plate is inserted and attached to the L-shaped locking piece at the rear end of both side plates, so that assembly is easy and the rear part of the drawer in the mutually assembled state can be easily assembled. It is an object of the present invention to provide a rear structure of an assembly type drawer having a strong structure.

To further explain the details of the present invention with reference to the illustrated embodiments, FIG.
3 is a side plate, 3 is a rear plate, and 4 is a bottom plate, and these components are assembled to form the main assembly type drawer.

As shown in FIGS. 2 and below, this drawer is provided with a drawer accommodating portion in the front plate portion shown as 1 in the drawings. The front plate part 1 is substantially box-shaped as shown in the figure, and a back cover with a central part protruding, shown as 6 in the figure, is fitted onto the back side of a front plate 5 forming a front plate, and the two are fixed together. Two upper and lower insertion openings 8, 8 are provided on both sides of the protrusion 7 in the back cover 6, and locking openings 9 are provided below the protrusion 7. The insertion ports 8, 8 are holes for receiving a protruding portion of the side plate 2, which will be described later, and the locking holes 9 are holes for receiving a locking piece provided at the front end of the bottom plate 4.

The side plate 2 is attached to the front plate 1 by inserting the two upper and lower protrusions 13, 13 formed at the front end of the front plate 1 into the insertion openings 8, 8 of the front plate 1. In addition, it can be connected to the bottom plate 4 at its lower end. That is, as shown in the illustration, the side plate 2
Bend the top end of the board 10 outward in an L shape to make the top end L.
A mold bent part 11 is formed, and a lower end L-shaped bent part 12 is formed inwardly at the lower end. The front end sides of these L-shaped bent parts 11 and 12 are formed by cutting out a part of the substrate 10 to form protruding parts 13 and 13, and between both the protruding parts 13 and 13, that is, between the L-shaped bent parts 11 and 12. A mounting piece 14 for attaching the side plate 2 to the front plate portion 1 with screws or the like is formed by bending. An L-shaped locking piece 15 is bent inward at the rear end of the side plate 2, and the L-shaped locking pieces 15, 15 at the rear ends of the two side plates 2, 2 are connected to each other.
This makes it possible to attach a rear plate 3, which will be described later.
As shown in the figure, the bottom plate 4 includes L-shaped bent portions 16 that are fitted into the L-shaped bent portion 12 at the lower end of the side plate 2 on both sides of a plate having an area that forms a drawer accommodating portion.
16, and the L-shaped bent portions 16, 1 on both sides of the bottom plate 4 are provided.
6 is fitted into the L-shaped bent portions 12, 12 at the lower ends of the side plates 2, thereby connecting the lower ends of the side plates 2 to each other via the bottom plate 4. At the tip of the bottom plate 4, protruding locking pieces 17 are provided that can lock into locking holes 9 provided at the lower part of the front plate portion 1. The locking piece 17 is a locking claw-like member inserted into the locking opening 9, and is fixed by spot welding or the like so as to project forward from the lower surface of the bottom plate 4. Further, at the rear end of the bottom plate 4, a rear end upright piece 18 is formed upwardly as shown in the figure. The standing piece 18
is for receiving the lower end of the rear plate 3, which will be described later, and preventing it from moving rearward.

Next, as shown in the figure, the rear plate 3 has L-shaped bent pieces 19, 19, which are vertically erected at both ends and which can be fitted into the grooves formed by the locking pieces 15 at the rear ends of the side plates 2. At the same time, from the upper end of the rear plate 3 to the rear, the rear plate 3
L-shaped bent piece 19 and side plate 2 to be fitted onto this
L-shaped locking piece 20 that can cover the L-shaped locking piece 15 of
are coupled.

Therefore, the rear plate 3 has columnar L-shaped bends provided on both sides of the rear plate 3 in vertical grooves formed by the L-shaped locking pieces 15 of the side plates 2 standing up on both sides of the bottom plate 3. Piece 1
L-shaped bent pieces 19 on both ends of the rear plate 3 are provided rearward from the surface and the upper end so that the L-shaped locking pieces 20 bent backward from the upper end of the rear plate 3 can be installed inside the rear plate 3. There is an L-shaped locking piece 20 between the inner surfaces of the side plate 2.
It is necessary to provide a gap for receiving the mold locking piece 15.

Further, the lower end of the rear plate 3 is connected to the L-shaped locking piece 20 at the upper end.
The lower end is bent into an L shape to form a rising piece 21 for supporting the lower end. The rising piece 21
Therefore, the rear end upright piece 18 of the bottom plate 4 is provided in contact with the rear end upright piece 18 of the bottom plate 4, and an engagement hole 22 is provided in the rear end upright piece 18 of the bottom plate 4 to prevent it from coming off upward.
Further, the hole 22 is formed on the outer surface of the rising piece 21 of the rear plate 3.
It is provided with a protrusion 23 that engages with the rear end of the bottom plate 4, and a convex portion 24 is formed at an appropriate position on the surface of the bottom plate 4 that sandwiches the rear end upright piece 18 of the bottom plate 4 and the rear plate 3.

However, in order to assemble such a protrusion,
Projecting parts 13, 13 at the front end of each side plate 2 relative to the front plate part 1
by inserting the L-shaped bent portions 16, 16 on both sides of the bottom plate 4 into the grooves formed by the lower L-shaped bent portions 12 at the lower end of the side plate 2,
By engaging the locking piece 15 at the front end with the locking opening 9 of the front plate 1, the front plate 1, side plates 2, and bottom plate 4 are assembled together.

Next, the column-shaped L that stands up above and below both sides of the rear plate 3
The shaped bent pieces 19, 19 are inserted into the L-shaped locking pieces 15, 15 formed inside the rear end of the side plate 2, and the L-shaped locking piece 20 formed at the upper end of the rear plate 3 is inserted into the side plate 2.
The L-shaped locking pieces 15, 15 are fitted externally on the outer surfaces of the rear plate 3, and one L-shaped locking piece 15 is connected to the other bending piece 19, and the upper end locking piece 20 is attached to the front and back sides of the rear plate 3. Movement in the direction and width direction is fixed.
The movement of the lower end of the rear plate 3 is regulated by an upward retaining means formed between the rear end rising piece 18 raised from the rear end of the bottom plate 4 and the lower end rising piece 21 of the rear plate 3. Can be assembled.

As described above, the rear structure of the assembly type drawer according to the present invention is formed by bending and connecting the L-shaped locking pieces inward from the rear end of the side plate, and forming the above-mentioned locking pieces for assembly at both ends of the rear plate. While connecting the L-shaped bent piece that fits inside the groove,
An L that can be externally fitted onto the locking piece of the side plate from above at the upper end.
It is made by connecting the locking pieces of the mold, and can be assembled by inserting and attaching the bent piece of the rear plate into the L-shaped locking piece at the rear end of both sides, making it easy to assemble. The side plates, rear plate, and bottom plate are strongly assembled together in the front, back, and width directions, and columnar members with locking pieces and bent pieces are positioned in the vertical direction at the corners of the side and rear plates to prevent loads from above. In addition, the locking piece on the upper end of the rear plate is fitted externally to the upper side of the locking piece on the side plate, thereby providing a stable assembly without slight movement.
