[0009]

EXAMPLES Hereinafter housing section vertical movement support unit and the present invention
An embodiment of a storage device using this will be described with reference to FIGS.

In this embodiment , as shown in FIG. 1 to FIG. 3, an elevating / lowering storage unit in which an elevating / lowering support unit A for an accommodating unit is accommodated in an accommodating board B and a car-type accommodating unit C is supported so as to be able to elevate.
This shows the case of a device .

As shown in FIGS. 4 to 6, the storage unit elevating and lowering support unit A connects the parallel links 1, 2 on both sides for supporting the storage unit C between the free ends to the left and right mounting bases 3, 4. The pivots 5, 6 which are individually pivotally supported and which oppose the opposed front links 1 a, 2 a of the parallel links 1, 2 on both sides and which rotate together with the same are integrally connected by a coupling shaft 17. .
As a result, the mounting bases 3 and 4 are integrated, and the parallel links 1 and 2 on both sides are interlocked.

Therefore, since the parallel links 1 and 2 on both sides pivotally supported by the mounting bases 3 and 4 constitute a unitized lifting support unit A for a storage unit, the entire unit is treated as one unit, and each unit is handled as one unit. Mounting bases 3 and 4 for storage board B
Can be easily attached to the inner surfaces on both sides by screws 10 or the like without the need for a special alignment work between the two. When the pivots 7 and 8 of the rear links 1b and 2b are also connected and integrated, the rigidity of integration of the mounting bases 3 and 4 and the interlocking rigidity of the parallel links 1 and 2 on both sides can be further increased.

The parallel links 1 and 2 are located between the free ends of the front and rear links 1a and 1b, and the links 2a and 2b.
Between the free ends of the mounting seats 1c, 2c
In a state where the storage unit C is not supported by the connection unit c, a complete parallel link on the storage unit lift support unit A side is formed. Therefore, the parallel link 1,
In order to support the storage portion C between the two free ends, the mounting seats 1c and 2c may be mounted on both side plates 9 of the storage portion C with screws 10 or the like.

Due to such an assembling structure, the storage device of this embodiment in which the storage unit lifting support unit A is stored in the storage board B and the storage unit C is supported so as to be able to move up and down is assembled easily and quickly with a small number of work steps. be able to. The storage section C supported by the storage section elevating and lowering support unit A in the storage board B is stored by the parallel links 1 and 2 on both sides being raised and lowered on the mounting bases 3 and 4 about the pivots 5 to 8. The storage board is moved up and down between a storage position located in the board B as shown in FIGS. 1 and 2 and a take-out position in which the storage board B is pulled out and lowered as shown in FIG.

Since the parallel links 1 and 2 on both sides cooperate with each other, there is no difference in the support and movement of the storage section C by the parallel links 1 and 2 on both sides, and the parallel links 1 and 2 on both sides are free. Even if the storage portion C supported between the ends is a simple low-rigidity type such as the cage type shown in the drawing, the storage portion C exhibits sufficient support rigidity to prevent the storage portion C from being twisted or shaken. , Can be made light and small as a whole.

On the other hand, the pivots 7, 8 pivotally supporting the rear links 1b, 2b on the rear side of the parallel links 1, 2 and rotating together with them.
Between the mounting bases 3 and 4, damper mechanisms 11 and 12 for operating the speed of lowering the storage portion C of the parallel links 1 and 2 to the take-out position are operated. This damper mechanism 1
Even if only one of the pivots 7, 8 works on one of the pivots 7, 8, the parallel links 1, 2 on both sides can work together. Even if the two damper mechanisms 11 and 12 are shared and operated, they can be equally applied to the parallel links 1 and 2 on both sides regardless of whether they are of the same type.

The damper mechanisms 11 and 12 are provided with mounting bases 3a having both ends of the mounting bases 3 and 4 bent outward.
It is accommodated and operated in the space between the spaces 4a and between the mounting seats 3a and between the mounting seats 4a.

The damper mechanisms 11 and 12 are operated by utilizing the rotation of the pivots 7 and 8, and are mounted on the support structure of the links 1a and 2b separated from the links 1a and 2b.
It can be provided compactly by utilizing the rotation operations of ~ 8.

Specifically, one damper mechanism 11 operates a spiral spring 21 and a rotary oil damper 22, and the other damper mechanism 12 operates only a spiral spring 31.

The helical spring 21 of the damper mechanism 11 is wound around a portion of the pivot 7 projecting inward from the mounting plate 20. As shown in FIGS.
A large diameter is received by a locking member 25 welded to the inner surface of the mounting plate 20, and the other end 21 b of the mounting plate 20 is rotatably mounted on the pivot 5 between the mounting plate 20 and the mounting base 3. And with a play S against the push pin 24 attached to any of the plurality of attachment holes 23 on the gear 26 of FIG.

As a result, when the gear 26 rotates in conjunction with the operation of the parallel links 1 and 2 falling down in the direction of the arrow shown in FIG. First, the end 21 of the spiral spring 21
b, but the play S disappears at a predetermined intermediate position where the inclination of the parallel links 1 and 2 increases and the weight of the storage section C increases the downward movement speed. The spiral spring 21 is gradually charged between the one end 21a which is pushed by the first member 21b and the one end 21a received by the locking member 25, and the weight of the storage portion C increases the descending speed. Even if the influence is caused as described above, the influence is reduced by the resistance at the time of the charging operation, so that the parallel links 1 and 2 can descend at a low speed.

On the other hand, the helical spring 31 of the other damper mechanism 12 is provided substantially in the same manner as the helical spring 21 by the pivot 8 and the rotary disk 32 mounted on the pivot 8 instead of the gear 26. One end 31 of the spiral spring 31
The point that “a” is received by a locking bolt 33 screwed to the mounting plate 20 is different from the case of the spiral spring 21.

By rotating the locking bolt 33, the locking bolt 33 advances to a position facing the end 32a,
It can be retracted from this facing position. By setting the locking bolt 33 to the retracted position, the other end 31 b of the spiral spring 31 is moved to the pushing pin 2 on the turntable 32.
4, the helical spring 31 is only idled around the pivot 8 because the locking bolt 33 does not receive the end 31a even if it is pushed toward the one end 31a. 2, does not have a damper function. However, by setting the locking bolt 33 to the advanced position, the end 31b of the spiral spring 31 is moved by the pushing pin 24 to the end 31b.
a, the end 31a is fixed to the locking bolt 3
Since the spring 3 receives and does not escape, the spiral spring 31 is charged between both ends 31a and 31b, and exerts a damper function on the parallel links 1 and 2 like the spiral spring 21.

Thus, when the damper mechanism 12 is operated or not operated by moving the locking bolt 33 forward or backward, the damper function can be enhanced or weakened in accordance with the weight of the object stored in the storage section C. . However, a plurality of such spiral springs can be mounted on the same pivot and selectively operated.

The gear 26 is provided with an arc-shaped long hole 26a through which a stopper pin 34 firmly mounted between the mounting base 3 and the mounting plate 20 passes.
At the position of the parallel links 1 and 2 where the storage section C descends to the removal position, the end of the elongated hole 26 a is
To prevent the parallel links 1 and 2 from rotating further downward. This prevents the storage section C from being excessively lowered below the predetermined take-out position.

The connecting shaft 17 connecting the pivots 5 and 6 is, for example, a pipe member as shown in the figure, and is screwed into the end portions 5a and 6a projecting from the mounting bases 3 and 4 of the pivots 5 and 6. The connection shaft 17 is fixed by 35 so that different lengths of the connection shaft 17 can be selectively used or replaced. Accordingly, it is possible to support the storage boards B having different lateral sizes and to support the storage section C having a size suitable for the storage boards B so as to be able to move up and down. Between the lower front portions of both side plates 9 of the storage section C, a handle 9a for elevating operation is provided.
Is installed.
