Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a sliding drawer device for, for example, a desk or a letter case.

[Prior Art] Conventionally, this type of drawer device includes a housing having an opening, and at least a front wall, a bottom wall, and left and right side walls that are slidably held within the housing and close the opening. It is known that the drawer body is provided with a hollow drawer body.

[Problems to be solved by the invention] However, with the above-mentioned conventional drawer device, when documents are stacked vertically inside the drawer body,
Since the drawer body is surrounded by walls on all sides, when removing documents from the lower tier, it is necessary to first remove the documents stacked on top of it one by one and then remove the lower tier documents, or to grope inside the drawer itself. The only way to do this is to pull out the documents at the bottom, which not only makes it troublesome to take out the documents, but also
There was a problem in that when the user tried to grope inside the drawer body and pull out documents from the lower tier, the documents were likely to bend or become damaged. It is also inconvenient when inserting other documents between stacked documents or manually searching through documents.

Therefore, if the front wall of the drawer body can be opened and closed, it will be easier to take out the documents at the bottom, but the open front wall will get in the way, and if the drawer body is deep, it will be difficult to take out the documents at the back. There is a drawback.

The present invention is intended to solve the above-mentioned problems, and its purpose is to provide a drawer device that makes it easy to take out, store, and organize documents, etc. from the drawer body.

[Means for Solving the Problems] Therefore, the present invention is intended to achieve the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

In the drawer device according to claim 1, both lower ends of the front wall 7 are pivotably supported relative to the left and right side walls 4, 5, and
Provided between the front wall and the side wall are releasable locking means (e.g. indentations 18, 19) for holding the front wall in an upright and rotated position and for sliding at least a portion of the bottom wall relative to the side wall. The present invention is characterized in that a slide mechanism (for example, a rack 26 and a pinion gear 27) is provided between the front wall and the bottom wall to move the bottom wall forward by rotating the front wall toward you.

The drawer device according to claim 2 is characterized in that the front wall 7 of the drawer main body 2 can be stored substantially parallel to the bottom wall 8.

[Function] In the drawer device according to claim 1, the drawer main body 2
To take out the documents 31 inside, it is sufficient to pull the drawer main body forward from the housing 1, then release the locking means 18, 19, and then pull down the front wall toward the front. When the front wall is pulled down in this manner, the slide mechanisms 26 and 27 are operated, and the bottom wall 8 moves forward relative to the left and right side walls 4 and 5 (FIGS. 2 and 6). Therefore, as the bottom wall moves forward, the documents move forward together, so that the documents can be taken out from the open front surface of the drawer main body.

On the other hand, in order to store the document in the housing, the front wall is raised to an upright position. In this state, the front wall is held upright by the locking means (third
~Figure 5). Furthermore, when the front wall is closed, the bottom wall retreats via the slide mechanism, and the documents also retreat together into a predetermined position. After closing the front wall in this way,
The drawer body may be pushed into the housing, and the opening of the housing is closed by the upright front wall of the drawer body.

In the drawer device according to claim 2, the drawer main body 2
When the front wall 7 is opened, the front wall can be stored under the bottom wall 8 (FIG. 6).

[Example] The present invention will be described below based on an example shown in the drawings.

In the figure, numeral 1 indicates a multistage housing such as a document cabinet, and numeral 2 indicates a drawer body that enters and exits from an opening 3 of the housing 1.

The drawer main body 2 is box-shaped with an open top surface,
The left and right side walls 4, 5 and the rear wall 6 are connected in a U-shape, the front wall 7 is pivoted at both ends of the left and right walls 4, 5, and the lower end of the left and right walls 4, 5 is slidably held. It consists of a bottom wall 8.

The front wall 7 is provided with a pair of left and right bearing parts 9, 9 which protrude laterally from the inner surface of the lower part thereof, and each bearing part 9 has a pair of tongue pieces 10, 10 which extend rearward in parallel and slightly apart from each other laterally. At the tip of each tongue piece 10, shaft holes 11 are formed in series horizontally.

Further, the left and right side walls 4 and 5 have slits 12 and 12 into which the bearing portion 9 of the front wall 7 is fitted from each front end surface.
V-shaped notches 15 are formed in the inner and outer pieces 13 and 14, which face each other with the slit 12 in between.
... are respectively provided, and a tongue-shaped elastic piece 16 is formed inside the V-shaped notch 15.
On the inner surface of the tip of each elastic piece 16, there is a protruding shaft 17 that protrudes briefly inward into the slit 12 and is large enough to fit into the shaft hole 11 of each tongue piece 10 of the front wall 7 that is fitted into the slit 12. (4th,
Figure 5). The height of the protruding shaft 17 is equal to the height of the tongue piece 1 of the front wall 7.
It is preferable to make the thickness lower than the plate thickness of 0, for example, about 1/3 of the plate thickness. Further, the lower part of the front edge of the outer side piece 14 is cut out in an arc shape to form an arcuate surface 14' so that the front wall 7 can be opened about the protruding shaft 17 without any problem.

Also provided between the front wall 7 and the side walls 4, 5 are releasable locking means for holding the front wall 7 in an upright and pivoted position. The locking means consists of concave and convex portions 18 and 19 that engage with each other, and the concave and convex portion 1
8 and 19 are provided on the front wall 7, and the other is provided on the side walls 4 and 5, respectively.

The recesses 18 are provided on the inner surfaces of the side walls 4 and 5, in this case on the inner side pieces 13, respectively. As shown in FIG. 5, the convex portion 19
The slide lever 20 is slidably held on the front wall 7 via the outer case 21, and the convex portion 19 is constantly pushed out from the outer case 21 by the force of a spring 22 inside the outer case 21. , projecting outward. Further, the convex portion 19 has a sawtooth shape, with its slope 19' facing rearward. In addition, the uneven portion 18,
Although a pair of 19 are provided on both the left and right sides, only one side may be used.

The bottom wall 8 is slidably held by the side walls 4 and 5, and a slide mechanism is provided between the front wall 7 and the bottom wall 8 to move the bottom wall 8 forward by rotating the front wall 7 toward you. establish.

As shown in FIG. 4, a pair of left and right projecting edges 2 with a convex cross section are provided on both left and right edges of the bottom wall 8.
3, 23 are provided, and on the other hand, a pair of left and right guide grooves 24, 24 with a concave cross section are provided on the inner surfaces of the lower end portions of the side walls 4, 5, into which both the protruding edges 23 of the bottom wall 8 fit, respectively. Further, at the rear end of the bottom wall 8, as shown in FIG. 1, an L-shaped upright back wall 25 is provided.

The slide mechanism meshes with the rack 26, pinion gear 27, and the front wall 7.
It consists of a drive gear 28 that rotates together with the drive gear.

A pair of left and right racks 26 are fixed to the front left and right sides of the upper surface of the bottom wall 8 along the sliding direction of the bottom wall 8. Further, the rack 26 is located within the thickness of the left and right side walls 4, 5, as shown in FIG. Therefore, cutout parts 29, 29 into which the left and right ends of the bottom wall 8 fit are formed on the inner surfaces of the lower ends of the side walls 4, 5, respectively, and each rack 26 is positioned in both cutout parts 29,
The rack 26 moves along the cutout 29 and faces the slit 12 from below through the cutout 29. As shown in FIG. 1, on both sides of each rack 26 there are grooves cut out from the end face of the bottom wall 8, so that there is no problem when the front wall 7 rotates.

The pinion gears 27 are fixed in the slits 12 of the side walls 4 and 5, respectively, and in this embodiment are fixed to the shaft of an oil-type rotary damper 30, thereby fixing the rotary damper 30 in the slits 12. The reason why the rotary damper 30 is used is to prevent the front wall 7 from opening with force.

The drive gear 28 is mounted on the left and right bearings 9 of the front wall 7.
The driving gear 2
8 has protrusions 28', 2 projecting laterally on the left and right that fit into the shaft hole 11 of the tongue piece 10 at its center of rotation.
8' is provided, and both protrusions 28' are inserted into each shaft hole 11 using the elasticity of the tongue pieces 10 (4th and 5th
figure). Incidentally, since the drive gear 28 needs to rotate together when the front wall 7 is opened and closed, it may be fixed with an adhesive or the like if necessary. Furthermore, since the protruding shaft 17 of the elastic piece 16 of the side walls 4 and 5 fits into the shaft hole 11 of the tongue piece 10 from the opposite side, the height of the protrusion 28' is adjusted so that the two do not touch each other in the shaft hole 11. It is also preferable to make the thickness lower than the thickness of the tongue piece 10 of the front wall 7, for example, about 1/3 of the thickness.

Next, the assembly procedure of the drawer device having the above configuration will be described. After fixing the rotary damper 30 in each slit 12 of the side walls 4, 5, both projecting edges 23 of the bottom wall 8 are attached to the side walls 4, 5. By fitting the bottom wall 8 into each guide groove 24 and moving the bottom wall 8 backward along the guide groove 24, the rack 26 of the bottom wall 8 and the pinion gear fixed to the rotary damper 30 are engaged with each other (Fig. 3). ).

On the other hand, after attaching the drive gear 28 and the outer case 21 of the slide lever 20 to the front wall 7, align both bearing parts 9 with the slits 12 of the side walls 4 and 5 and insert them backwards. The protruding shaft 17 of each elastic piece 16 is fitted into the shaft hole 11 of each tongue piece 10 of the front wall 7 by utilizing the elasticity of the side wall 4,
The drive gear 28 of the front wall 7 and the pinion gear 27 of the rotary damper 30 are meshed with each other within the slit 12 of No. 5 (FIGS. 3 to 5).

Then, the front wall 7 is connected to the protruding shaft 1 of the left and right side walls 4 and 5.
7 to the upright state, and in this position, the protrusions 19 of each slide lever 20 protruding backward from the inner surface of the front wall 7 are pushed into the respective recesses on the inner surfaces of the side walls 4 and 5 by the biasing force of the spring 22. 18 and the front wall 7 is locked in an upright position (FIGS. 4 and 5). The drawer main body 2 assembled in this way is used by being inserted into the opening 3 of the housing 1. When the drawer main body 2 is pushed in, the front wall 7 of the drawer main body 2 is inserted into the opening 3 of the housing 1.
is blocked.

Next, the usage procedure will be explained.

First, when using the drawer main body 2, pull it out from the opening 3 of the housing 1, move both slide levers 20 on the left and right sides of the front wall 7 inwardly, and release the springs 2.
It slides against the urging force of 2. In this way, when the slide lever 20 is slid, the protrusion 1
9 are retracted from the respective recesses 18 on the inner surfaces of the side walls 4 and 5, and the front wall 7 becomes rotatable around the protruding shafts 17 of the left and right side walls 4 and 5. Therefore, all you have to do is pull down the front wall 7 toward you.

When the front wall 7 is pulled down toward the front, the front wall 7 rotates around the protruding shafts 17 of the left and right side walls 4 and 5, and at the same time, the drive gear 28 rotates integrally with the front wall 7. Drive gear 2
When 8 rotates, the rotary damper 3 engages with it.
0 pinion gear 27 rotates, rotating damper 3
A braking force of 0 is applied, and this braking force prevents the front wall 7 from opening suddenly and forcefully in a pattern. or,
Since the pinion gear 27 and the rack 26 of the bottom wall 8 are engaged, the bottom wall 8 moves forward.

Since the center of rotation of the front wall 7 is located behind the inner surface of the bearing 9, the front wall 7
rotates almost parallel to the bottom wall 8 about the protruding shaft 17 of the side walls 4, 5, and its inner surface is parallel to the side walls 4, 5.
The drawer body 2 reaches its maximum open position at the position where it touches the lower end of the drawer body 8, and is stored almost parallel to the bottom wall 8, opening the front surface of the drawer body 2 (FIGS. 1 and 6).

In addition, as the front wall 7 rotates, the bottom wall 8 also gradually moves forward, and the front wall 7 stops at the maximum open position.
The forward movement of the bottom wall 8 also stops, and at this maximum forward movement position, the front edge of the bottom wall 8 moves forward until it is almost flush with the tip end faces of the side walls 4, 5 (FIG. 6). Incidentally, as can be seen from this explanation, in the retracted position of the bottom wall 8, the third,
As shown in Fig. 5, its front edge is set back from the inner surface of the front wall 7 by the sliding amount of the bottom wall 8, and there is a gap between the two, and the bottom wall 8 is moved back by the front and back width of this gap. It is structured to move forward. This is because when the bottom wall 8 moves forward, the slide lever 20 of the front wall 7
This is to prevent it from hitting the outer case 21. Of course, if the locking means of the front wall 7 is provided in a position that does not interfere with the sliding of the bottom wall 8, the above-mentioned gap is unnecessary, and the bottom wall 8 can be made to protrude forward from the tip end surfaces of the side walls 4 and 5. is also possible.

In this way, when the front wall 7 is opened, the front surface of the drawer main body 2 is opened and the bottom wall 8 moves forward.
As shown in FIG. 2, even if the documents 31 are stacked vertically on the bottom wall 8, they move forward as the bottom wall 8 moves forward and can be freely pulled out from the open front surface of the drawer main body 2. is possible. Of course, the items that can be placed inside the drawer main body 2 are not limited to the documents 31.

On the other hand, in order to store the document 31 in the housing 1, the front wall 7 stored under the bottom wall 8 can be pulled out and raised. In this way, when the front wall 7 is pulled up, the protrusion 19 of the slide lever 20 protruding from its inner surface engages with the tip end surfaces of the side walls 4 and 5, and when the front wall 7 is strongly pushed in, the protrusion 19 The slope 19' is pushed against the inner surfaces of the side walls 4 and 5 and retracts against the biasing force of the spring 22,
When the convex portion 19 is located in the concave portion 18 of the side walls 4 and 5,
The restoring force of the spring 22 pushes the front wall 7 into the recess 18.
(Figures 3-5).

Further, when the front wall 7 is raised, the drive gear 28 rotates together with the drive gear 28, and the pinion gear 27 that meshes with the drive gear 28 rotates in the reverse direction, so that the bottom wall 8 retreats via the rack 26.

Finally, the closed drawer body 2 of the front wall 7 can be pushed into the housing 1, and the drawer body 2 is stored in the housing 1, and the opening 3 of the housing 1 is closed by the front wall 7 of the drawer body 2. (Figure 5).

FIG. 7 shows another embodiment of the present invention,
Partition plates 32 are provided above the bottom wall 8 in multiple stages spaced upwardly at predetermined intervals, and are slidable integrally with the bottom wall 8 and held so as to be slidable back and forth independently of the bottom wall 8. It is something that According to this embodiment, the documents 31 can be arranged and stored in multiple stages within the space between the partition plates 32, and when the front wall 7 is opened, the partition plate 32 moves forward together with the bottom wall 8,
Moreover, since each partition plate 32 can be pulled out further independently from the bottom wall 8, documents 31 can be taken out even more easily.

In the embodiment shown in the drawings, the drawer device according to the present invention is used in a document cabinet, but it can also be used in stationery, furniture, automobiles, etc.
It can be widely applied to sliding drawers in fields such as home appliances. Moreover, in addition to the drawer that slides laterally, as in this embodiment, there is a back wall 25 on the bottom wall 8.
If provided, it can also be used as a drawer that slides vertically. Furthermore, although the multi-stage housing 1 has been described as an example, the housing 1 may have one stage. Furthermore, the material of the housing 1 and the drawer body 2 may be wood, steel, or plastic.

Further, although the entire bottom wall 8 is slidably supported on the left and right side walls 4 and 5, at least a part of the bottom wall 8 may be made slidable, and the sliding portion of the bottom wall 8 is supported on the left and right side walls 4 and 5. On the other hand, it may be supported on a cantilever.

Furthermore, the locking means for the front wall 7 is not limited to the embodiment shown in the drawings, and for example, a so-called raised latch whose locking state can be released by pushing the front wall 7 can be used. If the release latch is used, the release lever or button on the front wall 7 can be omitted.

Furthermore, a rack 26 is attached to the slide mechanism of the bottom wall 8.
Although the front wall 7 and the bottom wall 8 are connected with a wire, the bottom wall 8 may be pulled forward with the wire when the front wall 7 is opened.

Also, although the front wall 7 was opened and closed manually,
The front wall 7 may be always biased in the opening direction by a spring or the like, or, since the opening/closing of the front wall 7 and the sliding of the bottom wall 8 are linked, the bottom wall 8 may be biased in the forward direction by a spring or the like. Alternatively, the front wall 7 may be kept energized at all times by, for example, releasing the locking means, and the front wall 7 can be automatically opened by simply releasing the locking means.

[Effects of the invention] Since the present invention is configured as described above,
This produces the following effects.

According to the drawer device according to the first aspect, since the front wall can be opened and the bottom wall moves forward at that time, it is possible to provide a drawer device in which it is easy to take things in and out.

According to the drawer device according to claim 2, when the front wall is opened, the front wall can be stored under the bottom wall, so the front wall does not get in the way when taking things in and out, making it smart and functional. It is possible to provide a drawer device with a wide range of functions.
