Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage unit which is configured so that two storage units arranged vertically can be exchanged vertically so that articles can be easily taken in and out of an upper storage unit in which articles are difficult to be taken in and out. The present invention relates to a lifting method and a lifting storage device using the same.

[0002]

2. Description of the Related Art As a method for raising and lowering a storage section between an upper position and a lower position, it is conceivable to raise and lower the storage section linearly on a vertical line. However, the weight of articles stored in the storage section has increased. At this time, since it is difficult to raise the storage unit, a lifting device that raises and lowers the storage unit by rotation has been proposed so that the storage unit can be raised with a lighter force. FIG. 6 shows a conventional example of a storage unit elevating device by rotation, which is configured so that the storage unit can be moved up and down by a link mechanism.

[0006] As shown in FIG. 6, this lifting device allows a storage section a housed in a cabinet c disposed above a work table such as a sink d to be moved up and down between the cabinet c and a lower position. Is configured. When the storage unit a is stored in the cabinet c, there is no problem in the operation of using the sink d. When the door of the cabinet c is opened and the storage unit a is pulled down as needed, the lower part where the storage part a can be freely taken in and out is provided. Can be lowered into position. The storage part a is a parallel link b rotatably attached to the cabinet c.
The storage section a is pivotally supported at the free end of the storage section a, so that the storage section a can be rotated between the inside of the cabinet c and the lower position on the front side to perform the elevating operation.

[0004] When an article is to be put in and taken out of the storage section when the storage section is disposed above, the article cannot be freely taken in and out without using a stepping board or the like. With this configuration, the upper space can be effectively used.

[0005]

However, in the above configuration, the storage section a is located at the lower position on the front side of the cabinet c. Therefore, when the storage section a is lowered, it becomes impossible to work on a worktable such as a sink. In addition, there is a problem that the cabinet c cannot be arranged at a very high position because the height distance for moving up and down is small. Also, when the weight of the storage section a due to the storage increases, a large force is required to raise the storage section a, and there is a difficulty in using a weak woman or child.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible to easily perform an operation of linearly moving a storage unit up and down, and to freely exchange the positions of two storage units arranged vertically. An object of the present invention is to provide a lifting method and a lifting storage device using the same.

According to the above construction, when the first storage section is horizontally moved to a position deviated from the arrangement position by the horizontal support means, the first storage section is displaced from the elevating shaft of the second storage section, and can be freely moved up and down. In this state, a force for raising and lowering the first storage unit is applied to the second storage unit by the interlocking means, and the second storage unit can be moved up and down in the opposite direction. The other can be lifted. Therefore, it is possible to easily perform the movement in the ascending direction that requires a large force when moving up and down linearly, and at the same time, the state of suddenly falling due to its weight at the time of descending is suppressed by braking that raises the other, and the ascending and descending And can be implemented in a well-balanced manner. The vertical position of the first storage unit can be changed by vertically moving the first storage unit by moving up and down, respectively, and then moving the first storage unit to the original position where the second storage unit moved.

Further, a pair of horizontal support means for supporting opposing surfaces of the first storage section are synchronously moved on a pair of first elevating support means, and the opposing rear sides of the second storage section are moved. In order to synchronously move the pair of second elevating means for supporting and elevating and lowering, there is provided a connecting shaft for connecting between a pair of interlocking means for interlocking the pair of first and second elevating means, and the connecting shaft. Can be provided at an upper corner on the opposite side to the position where the first storage portion in the storage portion is away from the arrangement position, and the first storage portion and the second storage portion are respectively provided. Synchronous lifting and lowering on both sides supported by the pair of lifting and lowering means enables smooth and stable lifting, and the respective lifting and lowering operations are linked by the interlocking means so that the lifting and lowering operations in opposite directions are performed. Synchronized elevating operation is performed by a connecting shaft that connects the interlocking means on both surfaces. By providing this connecting shaft at the upper corner of the housing, it is possible to arrange the space without providing a useless space in the housing.

Further, a means for reducing or canceling up / down torque by the first and second storage sections can be operated on the connecting shaft, so that the first storage section and the second storage section can be raised and lowered in proportion to each other. It is possible to alleviate the mismatch of the weight balance at the time of operation, and to perform a smooth lifting operation.

Further, the horizontal support means can be constituted as a telescopic support member. By extending the horizontal support means, the first storage section is moved horizontally to a position off the vertical axis of the second storage section, and contracted. By doing so, it can be returned to the original position.

Further, the first storage section and the second storage section can be arranged vertically so that the lower position is the eye level, and the lower position is the eye level. Because it is easy to see and take out the stored goods,
It is convenient to move the storage side of the article to be used up and down to the lower position, and the upper side can be moved up and down as needed to move it to the lower position. can do.

Next, when the first storage section 41 is horizontally moved to the original position of the raised second storage section 42 (d), the vertical positional relationship between the first storage section 41 and the second storage section 42 is changed. Interchange. By performing the reverse operation in the order from (d) to (a), the original vertical positional relationship can be restored.

The cabinet 43 is a tall storage section from the floor surface to the ceiling surface. The lower arrangement position of the first storage section 41 or the second storage section 42 is an eye level. In such a case, it is convenient to put in and take out the stored articles, but it is not easy to put in and out the articles in the upper arrangement position. However, according to the method of lifting and lowering the storage section, the upper arrangement position and the lower arrangement position of the first storage section 41 and the second storage section 42 can be interchanged as described above, so that the storage section on the necessary side is moved downward. Can be moved to the array position,
Both storage sections can be used effectively. When using a storage cabinet such as a locker or a closet to put articles in or out of a storage space at a high position, the use of a step platform or the like cannot be done without using a platform, but this storage section elevating method allows the upper storage space to be used effectively, Effective use of the limited space can be achieved.

Next, an embodiment of an ascending / descending storage device using the above-mentioned ascending / descending portion lifting / lowering method will be described with reference to FIG.

FIG. 1 is a side view for explaining the structure and operation of the lifting storage device according to the present embodiment. The lifting storage device C comprises a first storage portion 41 and a second storage portion stored in a cabinet 43. 42 can be exchanged between the upper arrangement position and the lower arrangement position.

The interior of the cabinet 4 is divided into a lower space of approximately 1/3 in the height direction and an upper space of approximately 2/3 above the lower space, and a door is provided on the front surface of each. In the upper space, a first storage section 41 and a second storage section 42 constituting the lifting storage device C are arranged vertically, and the first storage section 41 is always in the upper arrangement position, and the lower storage position is always in the upper arrangement position. The second storage section 42 is stored in the second storage section 42. The upper and lower arrangement positions can be exchanged as needed. Next, a lifting mechanism for exchanging the arrangement position will be described.

The first accommodating portion 41 is supported by a pair of horizontal support members (horizontal support means) 44 on opposing surfaces thereof, and the support members 44 are provided on both opposing inner side surfaces of the cabinet 43 in a vertical direction. Fixed lifting guide (1st
(Moving means) 45 is movably supported. On the other hand, a sliding plate 46 is attached to the back of the second storage section 42, and the sliding plate 46 is fixed to the inner surface of the back of the cabinet 43 in the vertical direction by a slide rail (second rail).
(Moving means) 47 is supported so as to be able to move up and down freely. The horizontal support member 44 and the upper ends of the opposing surfaces of the second storage section 42 are connected to each other by a lifting wire (an interlocking means) 48.
Is supported by a first pulley 49 and a second pulley 50 attached to the top surface thereof so as to suspend both.

As shown in the front view of FIG. 2, the elevating mechanism is provided in a pair on the left and right, and the first pulley 4 in the left and right position is provided.
Since 9 and 49 are connected by the connecting shaft 51 and rotate synchronously, the pair of right and left lifting mechanisms move up and down in synchronization. When the connecting shaft 51 is disposed at the upper corner of the cabinet 43 on the opposite side to the direction in which the first storage section 41 is pulled out, the first storage section 41 and the second storage section 42 are connected to the cabinet. Even if it is configured to be stored in the entire space in the space 43, no wasteful space is formed simply by cutting out the upper rear corner of each of the storage sections 41 and 42.

Referring to FIGS. 1 (a) to 1 (d), with reference to FIGS. 1 (a) to 1 (d), the first storage section 41 in the upper arrangement position and the second storage section in the lower arrangement position will be described. An operation of exchanging the arrangement position with the unit 42 will be described.

First, from the state shown in FIG. 1A, the door 43a of the cabinet 43 is opened to open the front surface of the cabinet 43, and the first storage portion 41 located at the upper arrangement position is pulled out toward the user. Horizontal support member 44 supporting first storage section 41
As shown in FIG. 3, two first telescopic arms 44b and a second telescopic arm 44c are accommodated in a vertical part 44a supported by a vertical guide 45, and the second telescopic arm 44c is The first telescopic arm 44b is fixed to the side surface of the first storage part 41, so that when a force that pulls out the first storage part 41 in the horizontal direction is applied, the first telescopic arm 44b moves from the elevating part 44a to the second telescopic arm 44b.
The first telescopic arm 44c is pulled out of the first telescopic arm 44b, and the first storage section 41 is pulled out of the cabinet 43 as shown in FIG. By this operation, the vertical shafts of the first storage section 41 and the second storage section 42 are separated from each other, so that both can be raised and lowered at the same time.

From the state shown in FIG.
1 is lowered in the direction of lowering the horizontal support member 44.
Slides on the lift guide 45 and descends. Since the elevating wire 48 is connected to the horizontal support member 44, the elevating wire 48 is moved through the second pulley 50 and the first pulley 49 to the second storage position with the lowering operation of the first storage unit 41. The part 42 is pulled up in the ascending direction. When a lifting force is applied by the lifting wire 48 to the second storage section 42, the sliding plate 46 slides on the slide rail 47 and rises. That is, the first
The storage section 41 and the second storage section 42 are moved up and down in directions opposite to each other.

When the first storage portion 41 is lowered to a position where the horizontal support member 44 reaches the lowermost portion of the lifting guide 45, the sliding plate 46 is also moved to the lowermost position of the slide rail 47 as shown in FIG. Reaching the upper part, the second storage part 42 rises to the upper arrangement position. Then, the lowered first storage unit 4
1 is pushed into the cabinet 43, the horizontal support member 44 becomes the first and second telescopic arms 44b and 44.
Since c enters the elevating section 44a and contracts, as shown in FIG. 1D, the first storage section 41 moves horizontally and moves to the lower arrangement position.

According to the above operation procedure, the arrangement positions of the first storage section 41 and the second storage section 42 are exchanged. By performing the reverse operation of this operation procedure, the arrangement position can be returned to the state shown in FIG.

When the lower arrangement position is set to the eye level, the first storage portion 41 or the second storage portion 41 moved to this position is moved to this position.
Since the articles stored in the storage section 42 can be easily put in and out of the storage section 42 and used, the necessary one is moved to this position. Therefore, articles stored in the upper part of the tall cabinet 43 can be easily taken in and out, and the storage space can be effectively used.

The raising / lowering operation of the above-described configuration raises or lowers the second storage part 42 by the operation of lowering or raising the first storage part 41, so that the first storage part 41 and the second storage part 42 Since the load is raised by raising the second storage portion 42 when lowering the first storage portion 41, a sudden drop with weight is suppressed, while the second storage portion 42 is lowered when the first storage portion 41 is raised. Since the weight for lowering the storage portion 42 is added, the storage portion 42 can be easily raised. However, when there is a large difference between the weights of the articles stored in the first storage section 41 and the second storage section 42, the mutual weight balance is lost, so that the lowering or the raising may not be performed smoothly. . In preparation for such a case, the connecting shaft 51 common to the lifting mechanisms on both sides is used.
It is effective means to add a buffer function such as a rotary damper. For example, as shown in FIG.
When the connecting shaft 51 and the rotary damper 55 are connected by the gears 53 and 54 that rotate in conjunction with the rotation of the connecting shaft 51, the rotation of the connecting shaft 51 is suppressed by the rotary damper 55 using the viscous resistance of oil. Inconvenience of the elevating operation can be reduced.

Although the elevating and lowering storage device C described above is shown as being installed in the cabinet 43, it can be arranged above a work table or the like.

If the lower arrangement position in this case is set to the eye level of a person who stands up, the arrangement position between the first storage portion 41 and the second storage portion 42 is free, and the upper space is effectively utilized. it can. For example, when a personal computer is arranged on the work desk 52, the use of the personal computer requires many equipments and supplies such as a recording disk, but it is necessary to secure a space for storing these in the upper space. it can.

[0032]

As described above, according to the first aspect of the present invention, the vertical positional relationship between the first storage portion and the second storage portion which are vertically arranged can be freely changed. When the arrangement position is set to a position where articles can be taken in and out and used easily, the storage section at the upper arrangement position is also lowered to the lower arrangement position, so that free use is possible. Therefore, the upper storage portion which is difficult to utilize can be used effectively.

Further, according to the second aspect of the present invention, the first storage section is horizontally moved to a position deviated from the arrangement position to be disengaged from the elevating shaft of the second storage section, so that the first storage section can freely move up and down. A force for raising and lowering the first storage portion is applied to the second storage portion by the interlocking means, and the other can be pulled up by the operation of adding the weight when one is lowered. Therefore, it is possible to easily perform the movement in the ascending direction that requires a large force when moving up and down linearly, and at the same time, the state of suddenly falling due to its weight at the time of descending is suppressed by braking that raises the other, and the ascending and descending And can be implemented in a well-balanced manner. When the first storage unit moves up and down, the vertical position of the first and second storage units respectively moves, and then horizontally moves to the original position where the second storage unit has moved, the vertical position can be switched. When the lower array position is set to the eye level, it is easy to put and take out and use the stored articles, so if the side that stores the articles to be used is raised and lowered to the lower position, the convenience of use is good, and the upper position Can be moved up and down as needed to move it to the lower position, so that the articles stored on the upper side can be used easily.
