Can be lowered to a position. Since the storage portion a is pivotally supported by the free end of the parallel link b that is pivotally attached to the cabinet c, the storage portion a is moved up and down by rotating in the cabinet c and the front lower position. The action can be performed.
[0004]
When the storage unit is arranged on the upper side, when trying to put in and out the article from the storage unit, it can not be freely put in and out without using a step board or the like, but if the storage unit can be raised and lowered as described above, The upper space can be used effectively.
[0005]
[Problems to be solved by the invention]
However, in the above configuration, the storage unit a is in the lowered position on the front side of the cabinet c. Therefore, when the storage unit a is lowered, the work on the work table such as a sink cannot be performed, and the height distance to be moved up and down is small. Therefore, there is a problem that the cabinet c cannot be arranged at a very high position. Further, when the weight of the storage portion a due to the stored items increases, a large force is required to raise the storage portion a, and there is a difficulty in using weak women and children.

However, according to the method for raising and lowering the storage unit, as described above, the upper arrangement position and the lower arrangement position of the first storage unit 41 and the second storage unit 42 are interchangeable. It can be moved to the arrangement position, and both storage units can be used effectively. When putting in and out articles from a high storage space with storage cabinets such as lockers and chests, the use of the upper storage space can be effectively utilized by this storage part lifting method, although it can not be used without using a stepper etc. It is possible to effectively use a limited space.
[0018]
Next, an embodiment of a lifting / lowering storage device using the storage part lifting / lowering method will be described with reference to FIG.
[0019]
FIG. 1 is a side view for explaining the configuration and operation of the lifting / lowering storage device according to this embodiment. The lifting / lowering storage device C includes a first storage portion 41 and a second storage portion 42 stored in a cabinet 43. It is configured to be interchangeable between an upper arrangement position and a lower arrangement position.
[0020]
The interior of the cabinet 4 is partitioned into a lower space of approximately 1/3 in the height direction and an upper space of approximately 2/3 thereabove, and a door is provided on each front surface. In the upper space, a first storage portion 41 and a second storage portion 42 that constitute the lifting storage device C are vertically arranged, and the first storage portion 41 and the lower alignment position are always in the upper arrangement position. The second storage part 42 is stored in the upper and lower positions, and the upper and lower arrangement positions can be switched as necessary. Next, an elevating mechanism for exchanging the arrangement positions will be described.
[0021]
The first housing portion 41 is supported from the side by a pair of horizontal support members (horizontal support means) 44 on both sides of the opposite, the support member 44 in the vertical direction on both inner side surfaces facing each cabinet 43 A fixed lifting guide (first lifting means) 45 is supported from the side so as to be movable up and down. On the other hand, a sliding plate 46 is attached to the back surface of the second storage portion 42, and the sliding plate 46 is a slide rail (second lifting means) fixed vertically on the inner surface of the back portion of the cabinet 43. 47 is supported from the back so as to be movable up and down. The horizontal support member 44 and the upper ends of the opposing surfaces of the second storage portion 42 are connected by a lifting wire (interlocking means) 48, and the lifting wire 48 is attached to the top surface of the cabinet 43. The first pulley 49 and the second pulley 50 are suspended over and supported by both.
[0022]
As shown in the front view of FIG. 2, the lifting mechanism is provided in a pair of left and right, and the first pulleys 49, 49 in the left and right positions are connected by a connecting shaft 51 and rotate synchronously. Move up and down synchronously. When the connecting shaft 51 is disposed at the upper corner of the cabinet 43 opposite to the direction in which the first storage part 41 is pulled out, the first storage part 41 and the second storage part 42 are connected to the cabinet. Even if it is configured to be stored in the full space in 43, a useless space will not be formed simply by cutting out the rear upper corners of the storage portions 41,.
[0023]
With respect to the lifting / lowering operation of the lifting / lowering storage device C configured as described above, with reference to FIGS. 1A to 1D, the first storage portion 41 in the upper array position and the second storage portion 42 in the lower array position The operation of exchanging the array positions will be described.
[0024]
First, from the state of FIG. 1A, the door 43a of the cabinet 43 is opened, the front surface of the cabinet 43 is opened, and the first storage portion 41 at the upper arrangement position is pulled out. As shown in FIG. 3, the horizontal support member 44 that supports the first storage unit 41 includes two first extendable arms 44b and second extendable arms 44c in an elevating unit 44a supported by an elevating guide 45. Since the second telescopic arm 44c is fixed to the side surface of the first storage unit 41, when a force for pulling out the horizontal direction is applied to the first storage unit 41, the first telescopic arm 44b The second telescopic arm 44c is pulled out from the first telescopic arm 44b from the lifting unit 44a, and the first storage unit 41 is pulled out of the cabinet 43 as shown in FIG. By this operation, the lifting shafts of the first storage portion 41 and the second storage portion 42 are separated, so that both can be lifted and lowered simultaneously.
[0025]
When the first storage portion 41 is pulled down from the state shown in FIG. 1B, the horizontal support member 44 slides down on the lifting guide 45. Since the lifting / lowering wire 48 is connected to the horizontal support member 44, the lifting / lowering wire 48 is stored in the second storage via the second pulley 50 and the first pulley 49 as the first storage portion 41 is lowered. The part 42 is pulled up in the upward direction. When a lifting force by the lifting wire 48 is applied, the second storage portion 42 moves up by sliding the sliding plate 46 on the slide rail 47. That is, the first storage portion 41 and the second storage portion 42 are lifted and lowered in opposite directions.
[0026]
When the first storage part 41 is lowered to a position where the horizontal support member 44 reaches the lowest part of the lifting guide 45, the sliding plate 46 reaches the uppermost part of the slide rail 47 as shown in FIG. Thus, the second storage part 42 rises to the upper arrangement position. Next, when the lowered first storage portion 41 is pushed into the cabinet 43, the horizontal support member 44 contracts with the first and second extendable arms 44b and 44c entering the elevating portion 44a. As shown in FIG. 1 (d), the first storage part 41 moves horizontally and moves to the lower array position.
[0027]
The arrangement positions of the first storage part 41 and the second storage part 42 are exchanged by the above operation procedure. If the operation procedure is reversed, the arrangement position can be returned to the state shown in FIG.
[0028]
If the lower arrangement position is set to the eye level, the articles stored in the first storage unit 41 or the second storage unit 42 moved to this position can be easily put in and out, and the necessary one can be used. Move to this position. Therefore, the 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.
[0029]
The ascending / descending operation according to the above configuration is performed by raising or lowering the second storage portion 42 by an operation of lowering or raising the first storage portion 41 and balancing the first storage portion 41 and the second storage portion 42. Therefore, when the first storage portion 41 is lowered, a load for raising the second storage portion 42 is applied, so that a rapid lowering with weight is suppressed, while when the first storage portion 41 is raised, the second storage portion 42 is suppressed. Because the weight that falls is added, it can be raised easily. However, when there is a large difference in the weights of the articles stored in the first storage unit 41 and the second storage unit 42, the weight balance between the two may be lost and the lowering or raising may not be performed smoothly. . In preparation for such a case, it is effective to add a buffer function such as a rotary damper to the connecting shaft 51 common to the lifting mechanisms on both sides. For example, as shown in FIG. 4, when the connection shaft 51 and the rotary damper 55 are connected by gears 53 and 54 that rotate in conjunction with the connection shaft 51, the connection of the connection shaft 51 by the rotary damper 55 that uses the viscous resistance of oil. Since the rotation is suppressed, it is possible to alleviate the problem of the lifting operation due to the loss of the weight balance.
[0030]
Although the lifting and lowering storage device C described above is shown as a configuration equipped in the cabinet 43, it can also be disposed above a work table or the like.
[0031]
Figure 5 shows an embodiment which is arranged above the working table 52, the elevating housing device C ₁ is intended to attached the structure of the upper space of the previous cabinet 43 to the wall, workbench to work sitting in a chair Sufficient space can be secured above 52 and there is no hindrance to work on the work desk 52. In this case, if the lower arrangement position is set to the eye level of the person who has stood up, the arrangement position between the first storage section 41 and the second storage section 42 can be freely set, so that the upper space is effectively utilized. it can. For example, when a personal computer is arranged on the work desk 52, a lot of equipment and supplies such as a recording disk are required for its use, but it is possible to secure a space for storing and storing them in the upper space. it can.
[0032]
【The invention's effect】
As described above, according to the present invention , the vertical positional relationship between the first storage portion and the second storage portion arranged in the vertical direction is determined from the side portion by the horizontal support means and the first elevating support means. And the second lifting / lowering support means supported from the back so that it can be lifted / lowered can be freely switched. A certain storage part can also be lowered to the lower arrangement position and can be used freely. Accordingly, it is possible to effectively use the upper storage portion that is difficult to utilize.
[0033]
In particular , a force for raising and lowering the first storage portion can be applied to the second storage portion by the interlocking means, and the other can be pulled up by an operation that adds weight when one of the storage portions is lowered. Therefore, it is possible to easily move in the upward 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 when descending is suppressed by braking to raise the other, rising and falling Can be implemented in a balanced manner. After the first storage unit is moved up and down by the vertical movement of the first and second storage units and then moved horizontally to the original position where the second storage unit has moved, the vertical position can be switched, If the lower arrangement position is set to the eye level, it is easy to put in / out and use the stored articles. Therefore, if the side storing the articles to be used is moved up and down to the lower position, it is convenient to use the upper position. Can be moved up and down at any time and moved to the lower position, so that articles stored on the upper side can also be used easily.
