Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lifting and lowering storage device in which two storage units arranged in the vertical direction can be switched by moving up and down as needed.
[0002]
[Prior art]
The hanging cupboard has been originally used to effectively use the high space that tends to be a dead space. However, since the storage section is high, objects cannot be taken in and out without using a step or the like. Recently, a storage unit installed in a high place such as a hanging cupboard is supported so that it can be moved up and down, and an elevating storage device is proposed and put into practical use in which the storage and removal of objects is performed at the lower position and storage is performed at the 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 is housed in a storage cabinet 103. In the figure, reference numeral 104 denotes a work table such as a kitchen apparatus. References include JP-A-7-148029 and JP-A-7-148031.
[0003]
However, such a lifting and lowering storage device has a problem that the cabinet 103 cannot be arranged at a very high position because the height distance to be lifted is small. Further, 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, and there is a difficulty in using it by a weak woman or child. And when such a raising / lowering storage apparatus is installed in the upper part of work benches, such as a kitchen apparatus, as shown in FIG. 9, since the storage part 101 is in the lowered position on the front side of the cabinet 103, the storage part 101 is lowered. However, there is a problem that the work on the work table 104 such as a sink cannot be performed.
[0004]
Therefore, the present applicant has newly proposed a lifting and lowering storage device as shown in FIGS. That is, the lifting and lowering storage device shown in the drawing arranges two storage portions provided with cooperation means that cooperate with each other, so that when the upper storage portion is lowered by about 180 degrees of rotation, the lower storage device is moved with that force. It is possible to change the vertical position by raising the part. Specifically, the first storage unit 111 and the second storage unit 112 arranged in the vertical direction, the storage units are rotatably supported by support fulcrums 113 and 114, and the storage units are connected to each other. , 114, a support member 116 that rotates about a rotation fulcrum 115, a sliding support 117 that supports the rotation fulcrum 115 so that it can move in a direction perpendicular to its axis, and a first support A roller 118 is provided on the back of the storage unit 111, and the roller 118 is brought into contact with the back plate 119 a of the cabinet 119. Reference numeral 120 denotes a handle provided in the storage unit 112.
[0005]
In this lifting and lowering storage device, when the user holds the handle 120 and pulls the storage portion 112 forward, the support member 116 that supports the storage portion 112 and is connected to the storage portion 111 rotates around the rotation fulcrum 115. Therefore, the storage unit 112 moves in the upward direction and simultaneously moves the storage unit 111 in the downward direction. Since the roller 118 provided on the back of the storage unit 111 is in contact with the back plate 119a and does not allow the storage unit 111 to protrude rearward during movement, the support member 116 supports the rotation fulcrum 115 as a sliding support unit. It is moved forward through 117, and the replacement operation is completed while minimizing interference between the storage units 111 and 112.
[0006]
This proposed lifting and lowering storage device makes it possible to increase the height of the lifting and lowering as compared with the prior art, and it can be installed at a higher position, and even when the weight of each storage portion increases, one storage portion As a result of the downward movement, the force in the upward direction of the other storage portion can be reduced, and an elevating storage device that is easy to use for less powerful women, children, and the elderly can be realized. In addition, since the portion of the storage portion protruding forward from the storage box body is eliminated by the rotation of 180 degrees, there is an effect that it is possible to work on a work table such as a sink in a state where the storage portion is lowered. .
[0007]
[Problems to be solved by the invention]
In such an up-and-down changing type lifting and lowering storage device, the storage work is remarkably reduced by the up-and-down movement, but further improvement in the storage amount and the ability to put in and out the article in the storage portion is further required.
[0008]
The present invention provides an elevating and lowering storage device that is excellent in storage efficiency and putting in and out of stored articles while making use of the up-and-down switching storage function.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the lifting and lowering storage device of the present invention is fixed to the rack body of the first storage portion that moves up and down by horizontal movement and rotational movement in the first and second storage portions arranged vertically. A shelf is provided, and a movable shelf that is horizontally movable in the front-rear direction is provided in the rack body of the second storage unit that moves up and down in the vertical direction.
[0010]
With the above configuration, the first storage unit having a horizontal movement component is not a movable shelf, but a fixed shelf, and is configured so that a horizontal force is not applied to the shelf during the storage operation.
[0011]
The second storage section is provided with a movable shelf that can slide in the horizontal direction, and the storage workability of the stored articles is greatly improved by moving the movable shelf in and out. Here, since the second storage unit has no horizontal movement component during the lifting / lowering operation, the storage unit does not move in accordance with the horizontal loading / unloading operation of the movable shelf, and the usability is not hindered.
[0012]
Since articles can be stored in three dimensions up and down by the fixed shelves and movable shelves arranged in the respective storage units, the storage capacity is improved and the separability is facilitated.
[0013]
Accordingly, it is possible to realize a storage device that is excellent in storage efficiency and workability while taking advantage of the convenience of the up / down switching storage function.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
According to a first aspect of the present invention, there is provided a lifting and lowering storage device, wherein each of the first and second storage portions arranged in the vertical arrangement position and the first and second storage portions can be rotated to both ends of the support arm. a first housing portion supporting a second housing portion coupled to, replaced the vertical position of the first, second respective housing portion by rotating at a rotation fulcrum provided on the middle portion of the support arm a housing portion supporting means to movably supported, a sliding support portion supporting the rotating fulcrum on the axis perpendicular direction so as to be horizontally moved, and guide means for moving the one housing part substantially in the vertical direction It is equipped with.
[0015]
When the first storage portion is pulled out, the support fulcrum of the first storage portion is rotated forward about the rotation fulcrum of the support arm, so that the support fulcrum of the second storage portion is rotated backward. However, since the second storage portion guides in the vertical direction by the guide means that moves in the vertical direction, the support arm rotates while pushing the rotation fulcrum horizontally in the sliding support portion, Since the second storage unit moves in the vertical direction as the first storage unit rotates, the vertical positions of the first storage unit and the second storage unit can be switched smoothly.
[0016]
The lifting and lowering storage device according to claim 2 of the present invention has a configuration in which the shafts of the supporting fulcrum are arranged in a substantially vertical position even when the vertical positions of the first and second storage portions are interchanged in the vertical arrangement position. Thus, even if the storage portion is changed up and down, the storage portion does not protrude forward from the storage box.
[0017]
The lifting and lowering storage device according to claim 3 of the present invention is configured by engaging a slide body provided at the back of the second storage portion with a rail body provided with guiding means in the vicinity of the back surface of the second storage portion. It has guiding means, which enables the action of maintaining the horizontal posture of the second storage part and the two actions of guiding it in the vertical direction with a simple structure, and the center of gravity of the storage part is forward Since the rail body firmly supports the moment to move and rotate the rack body of the storage portion around the support fulcrum, it is possible to realize an elevating and lowering storage device with extremely high strength.
[0018]
The lifting and lowering storage apparatus according to claim 4 of the present invention includes a fixed shelf in the first storage portion and a movable shelf that is movable in the horizontal direction in the second storage portion, as is apparent from the above configuration. Storage efficiency is improved by installing shelves in each storage unit and storing the stored articles in a three-dimensionally high density in multiple stages. Further, by making the shelf of the second storage section slidable back and forth, the storage of articles having a deep depth and the ability to put in and out the articles arranged in the front and back are improved.
[0019]
In addition, when storing the article in the second storage unit, even if the movable movable shelf is slid back and forth horizontally, the second storage unit is restricted to move up and down only in the vertical direction. There is no movement of the storage section, and no trouble occurs in the storage work.
[0020]
On the other hand, since the first storage unit is not a slidable movable shelf and is a fixed shelf, the shelf moves even in the first storage unit that moves up and down by the combined movement of horizontal movement and rotational movement. It can be stored without worry.
[0021]
The lifting / lowering cabinet according to claim 5 of the present invention enables the storage work in the cabinet to be three-dimensionally stored vertically by arranging the lifting device of the present invention inside the cabinet whose front surface is open. If the number of shelves is appropriately set according to the above, the storage capacity can be improved and the separate storage capacity can be promoted.
[0022]

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 support arms 4L and 4R are connected by a connecting shaft 10, and left and right elevating mechanisms are provided. 1L and 1R are configured to operate in synchronization. As a result, the left and right sides of the first and second storage units 2 and 3 are integrally supported, and the left and right movements are prevented from being twisted or tilted even when the load is unbalanced between the left and right sides due to the offset of the stored items. This eliminates the difference between the two.
[0028]
The support arm 4L will be further described by taking the lifting mechanism 1L shown in FIG. 4 as an example. The horizontal movement shaft 11L is supported so that rollers 13a and 13b arranged on the upper and lower sides thereof are inserted into recesses formed in a U-shaped cross section on the upper and lower sides of the sliding support portion 6L, so that the sliding support portion 6L is horizontal.

Pull out the operation handle A. Then, since the support fulcrum P1 of the first storage unit 2 is rotated forward about the rotation fulcrum O of the support arm 4, the second storage unit 3 tries to rotate the support fulcrum P2 backward. Since the guide rail 9a receives the force applied to the guide roller 9b and guides the guide roller 9b in the vertical direction on the second storage portion 3 side, the support arm 4 rotates to support the rotation fulcrum O by sliding. While extruding in the horizontal direction within the portion 6, the second storage portion 3 rises in the vertical direction as the first storage portion 2 rotates as shown in FIGS. 5 (b) to 5 (d).
[0033]
When the first storage portion 2 is further rotated from the state shown in FIG. 5D, the rotation fulcrum O of the support arm 4 is drawn back in the direction returning to the original position, as opposed to the above. As shown in (f) to (f), the second storage part 3 further rises in the vertical direction in conjunction with the first storage part 2 entering the lower part of the cabinet 5 while rotating. As shown in FIG. 5G, when the first storage part 2 enters the lower position where the second storage part 3 was originally arranged, the second storage part 3 becomes the first storage part 2. Rises to the upper position where the original arrangement was made, and the arrangement positions of the first storage unit 2 and the second storage unit 3 are switched up and down.
[0034]
When the first storage unit 2 is pulled out from the state shown in FIG. 5G and is rotated in the direction opposite to the above operation, the second storage unit 3 is lowered in the vertical direction, and FIGS. The original arrangement position can be restored by the reverse operation of (a).
[0035]
In such an up-and-down switching operation of the storage units 2 and 3, the first storage unit 2 is supported by the support arm 4 so as to be pivotable about the support fulcrum P <b> 1 by one axis. The horizontal posture tends to tilt due to the shift of the center of gravity of the storage unit 2 or the rotation operation of the first storage unit 2. Here, the timing pulley 18 is spanned between the rotary pulley 16 fixedly supported by the first storage portion 2 and the fixed pulley 14 at the rotation fulcrum O, and is interlocked with the rotation without slipping. 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 as the first storage portion 2 rotates. As a result, the first storage unit 2 can always maintain its horizontal posture.
