Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to two vertically arranged cells.
The present invention relates to an elevating and accommodating device in which the upper and lower positions of the two accommodating portions can be changed by raising and lowering the accommodating portions as needed.

[0002]

2. Description of the Related Art Hanging cabinets have been used to make effective use of high spaces, which tend to become dead spaces.
However, since the storage is high, it is not possible to freely take things in and out without using a step or the like. Recently, we support the storage units installed in high places such as hanging cabinets so that they can be raised and lowered.
A lifting / lowering storage device has been proposed and put into practical use, in which items are put in and taken out at a lower position and stored at an upper position. That is, as shown in FIG. 9, the storage unit 101 is supported by a support arm 102 configured as a parallel link, and the storage cabinet 10
It is the one that has been decorated in 3. Reference numeral 104 in the drawing denotes a workbench such as a kitchen device. As a reference, JP-A-7-14802
9 and JP-A-7-148031.

However, in such an elevating / storing device, there is a problem that the cabinet 103 cannot be arranged at a very high position because the height distance for ascending / descending is small. Moreover, when the weight of the storage unit 101 increases due to the stored items, it is necessary to apply a large force to the operation for raising the storage unit 101, which is difficult for a weak woman or child to use.
When such an elevating storage device is installed on the upper part of the workbench such as a kitchen device as shown in FIG. 9, the storage unit 101 is in the lowered position because the front side of the cabinet 103 is in the lowered position. Then workbench 10 such as sink
There was a problem that I could not work in 4.

Therefore, the applicant newly added FIG. 10 and FIG.
I proposed a lifting storage device like this. That is, in the lifting and lowering storage device shown in the figure, by arranging two storage units provided with a cooperating unit that cooperates with each other in the vertical direction, the upper storage unit has about 18
When it is lowered by turning by 0 degree, the lower storage portion can be raised by the momentum and the upper and lower positions can be interchanged. Specifically, the first storage section 111 and the second storage section 112, which are arranged vertically, and the storage sections are rotatably supported by the support fulcrums 113 and 114, the storage sections are connected to each other, and the support fulcrum 113 is provided. , Fulcrum 1 set between 114
15, a support member 116 that rotates around the center, a slide support portion 117 that supports the rotation fulcrum 115 so that the rotation fulcrum 115 can move horizontally in a direction perpendicular to the axis, and the first storage portion 11
The roller 118 is provided on the back of the cabinet 1, and the cabinet 119
The roller 118 is brought into contact with the back plate 119a. Reference numeral 120 is a handle provided in the storage section 112.

This lifting and lowering storage device allows a user to hold a handle 120.
Grip and pull out the storage part 112 to the front,
Support member 1 supporting 2 and being connected to the storage section 111
Since 16 rotates about the rotation fulcrum 115, the storage part 112 moves in the ascending direction and simultaneously moves the storage part 111 in the descending direction. Since the roller 118 provided on the back of the storage section 111 abuts the back plate 119a and does not allow the storage section 111 to project rearward during movement, the support member 116 slides the rotation fulcrum 115 on the sliding support section. It moves to the front through 117, and storage parts 111, 1
The replacement operation is completed while the interference of 12 is minimized.

[0006] With this lifting and lowering storage device according to the present proposal, it is possible to make the height distance for lifting and lowering larger than in the past, and it is possible to install at a higher position, and even when the weight of each storage unit increases, The lowering momentum of the storage compartment can reduce the force of the other storage compartment in the upward direction, making it possible to realize a lifting storage device that is easy to use even for weak women, children, and the elderly. . In addition, since there is no protrusion of the storage portion to the front of the storage box body due to the rotation of 180 degrees, there is an effect that it is possible to work on a work table such as a sink with the storage portion lowered. .

[0007]

In such an up-and-down interchange type up-and-down storage device, the up-and-down up-and-down movement dramatically reduces the storage work, but improves the storage amount and the ability to take items in and out of the storage section. Further demanded.

The present invention provides an elevating / storing device which is excellent in the storage efficiency and the storage / removal property of stored items while making the best use of the upper / lower interchangeable storage function.

[0009]

In order to solve the above-mentioned problems, in the first and second storage units of the present invention, the first and second storage units vertically arranged are moved up and down by horizontal movement and rotational movement. The rack body of the storage unit is provided with a fixed shelf, and the rack body of the second storage unit which moves up and down in the vertical direction is provided with a movable shelf which is horizontally movable in the front-rear direction.

With the above construction, since the first storage portion having the horizontal movement component is a fixed shelf, not a movable shelf, and a horizontal force is not applied to the shelf during the storage work, there is no problem in usability.

Further, the second storage portion is provided with a movable shelf that is slidable in the horizontal direction, and by putting the movable shelf in and out, the workability of storing the stored articles is greatly improved. Here, since the second storage unit has no horizontal movement component during the up-and-down movement, the storage unit does not move along with the horizontal loading / unloading operation of the movable shelf, and the usability is not impaired.

Since the fixed shelves and the movable shelves arranged in the respective storage portions can store the articles vertically and three-dimensionally, the storage capacity is improved and the sorted storage ability is promoted.

As a result, it is possible to realize a storage device which is excellent in storage efficiency and workability while making the most of the convenience of the upper and lower interchangeable storage function.

Further, since the shelves are slidable back and forth, storage of deep-deep articles and insertion / removal of articles arranged front and back are improved.

When storing articles in the second storage unit, even if the slidable movable shelves are slid horizontally in the front and rear directions, the vertical movement of the second storage unit is restricted only in the vertical direction. As a result, the storage section does not move, and storage work is not hindered.

On the other hand, since the first accommodating section is a fixed shelf without disposing a slidable movable shelf, even if the first accommodating section performs a lifting operation by a combined motion of horizontal movement and rotational movement, the shelf is Can be stored without worrying about moving.

According to a second aspect of the present invention, there is provided a lifting / lowering storage device in which a rail body provided on an inner rear surface of the cabinet is provided with a second body.
Is provided with a guide means configured by engaging a slide body provided on the back surface of the rack body of the second storage portion, and by this, the function of maintaining the horizontal posture of the second storage portion and guiding it in the vertical direction. It enables two functions with a simple structure, and when the movable shelf provided in the second storage part is pulled out,
Since the rail body firmly supports the moment that the center of gravity of the storage portion moves forward and rotates the rack body of the storage portion around the support fulcrum, the lifting and storage device having extremely high strength can be realized. .

FIG. 4 is a sectional view of an essential part of one of the lifting mechanisms as seen from the front. FIG. 5 (a)-
(G) is a side sectional view for explaining a replacement operation sequence of the lifting mechanism in the embodiment.

As shown in FIG. 1, the lifting mechanism 1 includes a support fulcrum P1 of the first storage part 2 and a support fulcrum P of the second storage part 3.
2 is mounted on both side plates of a cabinet 5 which accommodates the accommodating portions 2 and 3 in a vertically arranged position and which has a front surface opened, and a rotation of the supporting arm 4. A sliding support portion 6 that supports the fulcrum O so as to be movable in the horizontal direction; a posture control means 7 for the first storage portion that maintains the first storage portion 2 in a constant horizontal posture regardless of the rotation angle; A guide means 8 for maintaining the horizontal posture of the storage part 2 of 2 and vertically controlling the movement path when the storage part 3 is moved up and down.
It has and. A guide rail 9a having a U-shaped cross section which constitutes the guide means 8 is attached to the back of the cabinet 5, and the guide rail 9a receives guide rollers 9b provided above and below the back of the second storage portion 3. To prevent the front-back movement and guide the storage unit 3 to move only in the vertical direction.

As shown in FIG. 2, the elevating mechanism 1 is provided as elevating mechanisms 1L and 1R at symmetrical positions, and the rotation fulcrums O of the supporting arms 4L and 4R are connected by a connecting shaft 10, and The elevating mechanisms 1L and 1R are configured to operate in synchronization. As a result, the first and second storage units 2 and 3 are integrally supported on the left and right, and even if the load is unbalanced due to the bias of the stored items, the left and right movements do not occur. The difference between the two is eliminated.

The lift mechanism 1L shown in FIG. 4 will be further described as an example. The support arm 4L is connected to the inner surface of the side plate of the cabinet 12 by the horizontal moving shaft 11L at the intermediate portion corresponding to the rotation fulcrum O thereof. Movably supported,
The horizontal movement shaft 11L has rollers 13a, 1 arranged above and below it.
3b is inserted into the recesses formed in a U-shaped cross section above and below the sliding support portion 6L so that the sliding support portion 6L can be smoothly moved in the horizontal direction. A fixed pulley 14L is fixed to the tip of the horizontal moving shaft 11L concentrically with the rotation fulcrum O.

Support fulcrums P1 at both ends of the support arm 4L
A rotary pulley 16L and a rotary wheel 17L are concentrically and rotatably mounted on the shafts 15La and 15Lb fixed to the P2 position, respectively.
However, the second storage portion 3 is fixedly supported by the rotating wheel 17L at substantially central portions of the side plates 2L and 3L.

The fixed pulley 14L and the rotary pulley 16 described above.
L is set to have the same diameter dimension, and a timing belt 18 is stretched between the two to form the attitude regulating means 7 of the first storage portion.

Here, the storage units 2, 3 by the lifting mechanism 1
The ascending / descending operation of will be described with reference to FIGS.

As shown in FIG. 5A, the cabinet 5
When the upper and lower positions of the first storage section 2 and the second storage section 3 stored in the above are switched, the operation handle A of the first storage section 2 having no guide roller 9b is pulled out to the front. Then, since the support fulcrum P1 of the first storage part 2 is rotated forward about the rotation fulcrum O of the support arm 4, the second storage part 3 tries to rotate the support fulcrum P2 backward. On the second storage portion 3 side, the guide rail 9a receives the force applied to the guide roller 9b, and the guide roller 9b
Since the guide is provided in the vertical direction, the rotation fulcrum O of the support arm 4 is pushed out horizontally in the slide support portion 6 by the operation of rotating the support arm 4, and as shown in FIGS. The storage portion 3 of the first storage container 3 rises in the vertical direction as the first storage portion 2 rotates.

When the first storage portion 2 is further rotated from the state shown in FIG. 5 (d), the rotation fulcrum O of the support arm 4 is pulled in the direction of returning to the original position, contrary to the above. As shown in (e) to (f), the first storage part 2 rotates and enters the lower part of the cabinet 5, and the second storage part 3 moves vertically. When it further rises and the first storage portion 2 enters the lower position where the second storage portion 3 was originally arranged as shown in FIG. 5 (g), the second storage portion 3 moves to the first storage position. The storage units 2 are moved to the upper position where they were originally arranged, and the arrangement positions of the first storage unit 2 and the second storage unit 3 are switched up and down.

When the first storage portion 2 is pulled out from the state shown in FIG. 5 (g) and rotated in the direction opposite to the above operation, the second storage portion 2
The storage part 3 of FIG. 5 descends in the vertical direction, and (f) to (a) of FIG.
The reverse operation of can restore the original array position.

In the above-mentioned upper / lower switching operation of the storage parts 2 and 3, since the first storage part 2 is supported by the support arm 4 on the support fulcrum P1 so as to be rotatable about one axis.
Due to the displacement of the center of gravity of the first storage unit 2 with respect to the support fulcrum P1 and the rotation operation of the first storage unit 2, the horizontal posture tends to tilt. Here, the rotary pulley 16 fixedly supported by the first storage unit 2 has a timing belt 18 stretched between the rotary pulley 16 and the fixed pulley 14 located at the rotation fulcrum O, and the rotary pulley 16 is rotationally interlocked in a slip-free manner. Now, the rotary pulley 16 and the fixed pulley 14 are set to have the same diameter, and the timing belt 18 has the same angle in the direction opposite to the direction in which the support angle of the support arm 4 changes due to the rotation of the first storage section 2. Only the first storage part 2 is rotated, and as a result, the first storage part 2 can always maintain its horizontal posture.

Next, a first embodiment of the present invention in which a storage shelf is arranged in a storage portion based on the above-mentioned lifting mechanism will be described with reference to FIGS. 6 and 7.

6 (a) to 6 (g) are side sectional views for explaining the replacement operation sequence in this embodiment. FIG. 7 is a sectional view of the main part of the front of the lifting / lowering storage device according to the embodiment.

The first and second storage units 2 and 3 are formed by a rack body having an open front surface, and a shelf 19 is mounted on the shelf receiver 24 attached to both side surfaces of the rack body in the first storage unit 2. It is installed on the ground.

The second storage unit 3 is provided with a movable shelf 20 which can be pulled out horizontally forward, and the movable shelf 20 is supported and moved on slide rails 21 attached to both side surfaces of the rack body. It is like this.

The shelves 19 and the movable shelves 20 arranged in the respective storage sections enable vertical and three-dimensional storage, and if the number of shelves is set appropriately according to the storage purpose, the storage capacity can be improved and the separate storage performance can be improved. Is promoted.

Here, when the movable shelf 23 of the second storage section 3 is pulled out and the articles 22a and 22b are to be taken in and out, the vertical movement of the second storage section 3 is restricted by the guide means 8 in the vertical direction. Since there is no moving component, movable shelf 20
The storage portion 3 does not move due to the horizontal operation force of the.

By pulling out the movable shelf 20, it becomes easy to take in and out a storage item 22a having a deep depth, and also when the small articles 22b are arranged in front and back, the storage items in front do not get in the way.

Further, when a heavy storage article 23 is loaded on the movable shelf 20 with the movable shelf 20 pulled out as shown in FIG. 6 (g), the center of gravity of the second storage section 3 is considerably forward of the support fulcrum P2. The guide rail 9a prevents the rack body of the storage unit 3 from rotating and moving, and maintains a horizontal posture firmly, although a moment acts to move and move the rack body of the storage unit 3 forward. In addition, the guide rail 9a has high rigidity, and the guide roller 9 that engages with the guide rail 9a
If the vertical distance h of b is large, the structure can be made extremely simple and the durability strength against the stored load can be made excellent.

Since the raising / lowering operation of the first storage section 2 is a combined operation of horizontal movement and rotational movement, a horizontal force is applied to the storage section 2 or the center of gravity with respect to the support fulcrum P1 is largely displaced forward. If you do, the storage part 2 will move and
It becomes impossible to stop at the storage work positions of (a) and (g).

Here, since the first storage section 2 has the shelf 19 of a style to be placed on the shelf receiver, the above-mentioned usability problem can be avoided.

In the present embodiment, the shelf 19 is detachably attached by the shelf receiver 24 and its vertical position can be adjusted. However, even if the shelf 19 is fixed to the rack body of the storage section 2 with a screw or the like, the object of the present invention. Can be achieved.

(Embodiment 2) Next, an elevating and retracting device according to Embodiment 2 of the present invention will be described with reference to FIG.

8 (a) to 8 (g) are side sectional views showing a lifting / lowering device according to the second embodiment of the present invention. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The second embodiment differs from the first embodiment in that the second storage portion 3 is maintained in a horizontal posture and the guide means 8 is provided in the vertical direction. Here, a system using the timing belt 18 similar to the first storage unit 2 is used as the horizontal posture holding means, and the link 25 is used as the means for restricting the movement in the vertical direction. Link 25 is one end 25
A is rotatably connected to the side surface 12 of the cabinet, and the other end 25b is rotatably connected to the support arm 4 to regulate the movement path of the second storage portion 3 in a substantially vertical direction.

When the first storage portion 2 is pulled out toward the front from FIG. 8A to FIG. 8D and the support arm 4 is rotated, the rotation fulcrum O moves forward due to the tensioning action of the link 25. Then, from (d) to (g), the rotation fulcrum O moves rearward due to the pulling action of the link 25, and at this time, the support fulcrum P2 is guided along a substantially vertical locus.

The fixed shelves 19 of the first storage unit 2 and the movable shelves 20 of the second storage unit 3 are the same as those in the first embodiment, and it is possible to realize an elevator storage device which is similarly excellent in storage workability.

[0048]

As described above, in the lifting / lowering storage device according to the first aspect of the present invention, the storage efficiency can be improved by storing the articles to be stored in three-dimensionally in the upper and lower stages, and the space can be effectively used. Utilization is promoted. Further, by making the shelves slidable back and forth, it is possible to improve the storage of deep-deep articles and the ability to take in and out articles arranged in the front and rear. Also,
By providing this movable shelf on the side of the second storage section that does not have a horizontal movement component during the lifting operation, the storage section itself does not move due to the back-and-forth sliding operation of the movable shelf, and storage work is performed. It does not cause any problems.

On the other hand, since the first accommodating section is a fixed shelf without arranging the slidable movable shelves, even if the first accommodating section performs the lifting operation by the combined movement of horizontal movement and rotational movement, the shelf is Can be stored without worrying about moving.

Further, in the lifting / lowering storage device according to the second aspect, the function of maintaining the horizontal posture of the second storage part and the two functions of guiding it vertically can be realized with a simple structure. When the movable shelf provided in the second storage unit is pulled out, the center of gravity of the storage unit moves forward and the rail body firmly supports the moment that tries to rotate the storage unit around the support fulcrum. It is possible to realize a high-strength elevator storage device.

As described above, according to the present invention, it is possible to realize an elevating and accommodating device which has an optimal accommodating form for the elevating and lowering characteristics of each accommodating portion and is extremely convenient and has a high accommodating efficiency.
