DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating and lowering support unit for a storage unit used for storing various items in a kitchen or the like.
The present invention relates to a lifting storage device using the same .

[0002]

2. Description of the Related Art Such an ascending and descending support unit for a storage section is used.
And a lifting and lowering storage device using the same are disclosed in Japanese Patent Application Laid-Open No. 61-154.
610 and the like.

In this device, a storage portion is supported between the free ends of parallel links on both sides individually pivotally supported on the inner surfaces of both sides of the storage board, and the storage portion is raised to a position above the storage board and below a front portion of the storage board. It is possible to move up and down between the unloading position and the unloading position. The tension spring is operated between the link and the fixed part so that the link pair can lower the storage part at a low speed, and the storage part is in the raised position in the inclined position where the parallel link is inclined backward from the vertical position. By supporting it, it is possible to prevent it from inadvertently protruding forward even in the event of an earthquake or the like and dropping to the take-out position, thereby ensuring safety in use.

[0004]

However, in the above-described conventional configuration , safety of use is ensured by supporting the storage portion at the storage position in the inclined position in which the parallel link is tilted backward from the vertical position. But the tension spring is
After the parallel link is raised from the backward inclined position to the vertical position, it works in the entire process of lowering it further to the unloading position.
And the lifting operation is performed over the entire stroke against the tension spring.
This is performed until the parallel link moves from the rearward inclined position to the vertical position, so that the storage unit is lifted, requiring a large force to start moving a stationary heavy object. In addition, the initial operation for pulling out the storage unit to the extraction position and lowering it is heavy, which is inconvenient to use.

An object of the present invention is to solve such a problem, to ensure sufficient safety and to be convenient for use.
It is an object of the present invention to provide a lifting support unit for a storage unit and a lifting storage device .

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-described object, the storage unit raising and lowering support unit according to the present invention has a base end side so that the storage unit can be raised and lowered between free ends. A parallel link pivoted to the mounting base, a damper mechanism to limit the lowering speed of pulling the storage unit from the storage position to the removal position, and a charge mechanism when the storage unit is pulled out of the storage position.
In the retracted position, the parallel link is tilted backward from the vertical position, and the parallel link has a play between the parallel link and the damper mechanism from the tilted position to a position immediately before the vertical position or to a position where the parallel link is almost vertical. Is provided.

In addition, the storage section is supported on the free end side of the parallel link on both sides
It is characterized by the following.

[0008]

According to the present invention, the parallel link is raised and lowered between the storage position and the take-out position which is pulled out to the lower front part of the storage position by raising and lowering the parallel link. Since the storage unit is supported in the storage position in the inclined position inclined to the rear side, the rear link moment is acting on the parallel link by the weight of the storage unit by itself, so the storage unit can be used even in the event of an earthquake. Since the parallel link does not inadvertently lift while rotating from the backward inclined posture to the vertical posture, it is possible to ensure the safety of use, and from this backward inclined posture immediately before or almost immediately to the vertical posture. By having a play between the parallel link and the damper mechanism until the vertical position, the storage section at the storage position is moved until the parallel link is immediately before the vertical position or almost vertical position. It is easy to use because it can be pulled out lightly without resistance by the damper mechanism, and it shakes greatly due to an earthquake or the like. since the mechanism works, adverse effects of the play, in particular rather than the name,
With the spring, the lowering operation of the storage part can be suppressed.

EXAMPLES Hereinafter housing section vertical movement support unit of the present invention Oyo
FIGS. 1 to 3 show an embodiment of a lifting storage device using the same .
This will be described with reference to FIG .

FIGS. 1 to 6 show a first embodiment of the present invention. In this embodiment, as shown in FIGS. 1 to 3, an elevator storage device in which an elevator support unit A for an accommodation unit is accommodated in an accommodation board B and supported so that a car-type accommodation unit C can be moved up and down. Is shown.

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 B is moved up and down between a raised position located in the board B as shown in FIGS. 1 and 2 and a take-out position 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.

The oil damper 22 is mounted on the inner surface of the mounting plate 20, and the pinion gear 27 mounted on the rotating shaft 22a shown in FIG. 6 meshes with the gear 26, and the pivot shaft 7 when the parallel links 1, 2 fall down. The rotation speed is increased and transmitted to the rotation shaft 22a.

Therefore, the rotating blade 22b attached to the rotating shaft 22a and the braking blade 22c in the oil damper 22
Is increased, and the rotational resistance of the rotary blade 22b by the oil sealed in the oil damper 22 is increased. Thus, the pulling speed from the position where the parallel links 1 and 2 start to fall down from the standing state to the position where the spiral spring 21 starts to work can be sufficiently limited with a small damper capacity.

The spiral spring 31 of the other damper mechanism 12
Is provided substantially in the same manner as the spiral spring 21 by the pivot 8 and the rotating disk 32 mounted on the pivot 8 instead of the gear 26. The difference from the case of the spiral spring 21 is that one end 31a of the spiral spring 31 is received by a locking bolt 33 screwed to the mounting plate 20.

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.

Accordingly, 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 FIG. 7, and is fitted to the end portions 5a and 6a protruding from the mounting bases 3 and 4 of the pivots 5 and 6. It is fixed by screws 35 so that connecting shafts 17 of different lengths 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, there are handles 9 for raising and lowering operation.
a is attached.

Screw holes 36 for mounting the mounting bases 3 and 4 are provided in multiple stages on the inner surfaces on both sides of the storage board B, and the height of the storage board B corresponds to the height of the storage board elevating support unit A. When the height of the storage unit C is higher than the total height in a state where the storage unit C is supported, the mounting height of the storage unit lifting support unit A to the storage board B can be freely changed according to the height of the user. .

FIGS. 7 and 8 show a lifting support unit for a storage unit according to a second embodiment of the present invention and a lifting and lowering unit using the same.
2 shows a delivery device . In this embodiment, the storage unit C is supported and stored so that the storage unit C can be raised and lowered between a raised position and a take-out position pulled out to the lower front part of the raised position by the parallel links 1 and 2 of the storage unit lifting support unit A. This is the same as the first embodiment in that a damper mechanism 11 for accommodating and mounting on the board B and restricting the descending speed of the accommodating portion C is operated.

In this embodiment, in particular, the parallel link 1 is shown in FIG.
As shown in FIG. 8A, the storage unit C is supported at the storage position in an inclined position inclined backward from the vertical position, and from this inclined position, the storage unit C is moved to a position immediately before the vertical position shown in FIG. A play is provided with the damper mechanism 11 up to a certain position. Specifically, there is provided a play SS in a predetermined rotation range between the gear 26 and the pivot shaft 7 in the rotary damper 22 of the damper over <br/> mechanism 11 as shown in FIG. 7 (b).

With this configuration, the storage section C is supported so as to be able to move up and down between the raised position and the take-out position pulled out to the lower front part of the storage position by raising and lowering the parallel links 1 and 2. However, as shown in FIG. 7 (a), the storage portion C is supported at the raised position in an inclined position inclined rearward from the vertical position. Since the rotating moment acts rearward, the storage portion C does not inadvertently lift while rotating the parallel links 1 and 2 from the backward inclined posture to the vertical posture even in the event of an earthquake or the like. Therefore, safety in use can be achieved.

In addition, the pivot 1 and the gear 26a pivotally support the link 1b of the parallel links 1 and 2 from this rearward inclined position to a position immediately before the vertical position or a position where the link 1b is substantially vertical. 8, the parallel links 1 and 2 move the storage portion C at the ascending position to the position shown in FIG.
It is immediately before or substantially vertical orientation of the vertical position shown in (a), until the play SS is eliminated as shown in FIG. 8 (b), the helical spring 21 of the damper mechanism 11 does not work well, the damper over Since it can be pulled out lightly without resistance by the rotary damper 22 of the mechanism 11, it is easy to use, and shaking due to an earthquake or the like is large, so that the parallel links 1 and 2 just before the vertical position or after reaching the almost vertical position. since the rotary damper 22 of the normal case as well damper over mechanism 11 works, harmful especially not by the play SS.

[0034]

According to the present invention, the storage portion is supported so that it can be moved up and down between the storage position and the take-out position pulled out to the lower front part of the storage position by the undulation of the parallel link.
The parallel link supports the storage unit in the storage position in an inclined position that is inclined more rearward than the vertical position, and the rear link momentum acts on the parallel link due to the weight of the storage unit, so that the storage unit can be used even in the event of an earthquake. Since the parallel link does not inadvertently lift while rotating from the rearward inclined position to the vertical position, safety in use can be achieved, and from this rearward inclined position, immediately before or almost vertical to the vertical position. Until the position where the posture is reached, the play between the parallel link and the damper mechanism allows easy pull-out without resistance by the damper mechanism, so that it is easy to use. after reaching immediately before or substantially vertical orientation of the orientation is, in the case of normal Similarly damper mechanism spring
Since working together, adverse effects of the play, in particular rather than greens, spring
In addition, the lowering operation of the storage section can be suppressed.
