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 and lowering storage 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. 14 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.

[0003] As shown in Fig. 14, this elevating device can move up and down a storage section a housed in a cabinet c arranged above a worktable such as a sink d 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. Since the storage section a is supported by the free end of the parallel link b that is rotatably attached to the cabinet c, the storage section a can be rotated between the inside of the cabinet c and the lower front position to perform the elevating operation. it can.

[0004] In addition to such a kitchen, cabinets are arranged so that the upper space is used as a place for storing articles. If the storage unit a can be moved up and down, the storage unit installed above 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.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of raising and lowering a storage section in which two storage sections arranged vertically can be moved up and down from an upper position to a position directly below the storage section so that the upper and lower sides can be exchanged. An object of the present invention is to provide a storage device.

[0007]

According to a first aspect of the present invention for achieving the above object, a first storage portion and a second storage portion arranged vertically are synchronized with each other around a rotation fulcrum therebetween.

As described above, the first and second storage portions are synchronously rotated around the rotation fulcrum therebetween, and each of the first and second storage portions is rotated by 18 degrees.
If it is rotated 0 degrees, the upper and lower positions can be exchanged. If the lower position is set to a position where it is easy to put in and take out the stored items, the upper storage portion can be arbitrarily moved to the lower position, and the upper storage portion can be moved. Part can be used effectively.

In a second aspect of the present invention, the first and second storage portions are arranged vertically, and the first and second storage portions are supported by predetermined support fulcrums. And a support member that rotates at a rotation fulcrum set between the support fulcrums.

According to the above structure, if the first and second storage sections connected by the support member are rotated by 180 degrees at the rotation fulcrum of the support member, the first and second storage sections vertically arranged are arranged. The storage part can be exchanged between the upper position and the lower position immediately below. It can be returned to its original state by rotating it further 180 degrees or in the opposite direction.

Further, the third invention of the present application is directed to a first and a second storage section, wherein the first and second storage sections are arranged vertically and each storage section is supported by a predetermined supporting fulcrum. And a support member that rotates at a rotation fulcrum set between each support fulcrum,

The above structure can be configured by providing the engaging portions at two points symmetrical with respect to the rotation fulcrum of the support member.
Since any one point of the engaging portion is always guided by the guide portion, if the engaging portion is alternately engaged with the guide portion, the ascending / descending path is regulated in a 360-degree direction, and each storage portion can be rotated in any direction. The upper and lower positions can be interchanged.

Further, the first and second storage portions are supported by a pair of support members on opposite sides, and a connecting shaft is provided for connecting the two so as to rotate the pair of support members synchronously. Then, the supporting members supporting the storage section on both sides rotate synchronously, so that a smooth rotating operation is performed.

Further, the connecting shaft is connected to the first and second supporting members by a supporting member.
By arranging at the intermediate position of the supporting fulcrum of each storage section, no space is generated between the storage sections, and the capacity of each storage section arranged within the limited space can be maximized. .

Further, by configuring the sliding support portion as a telescopic structure, even when each of the storage portions is arranged and rotated in the storage portion having a small depth, the sliding support portion of the telescopic structure can be used as a support member. The range of movement of the rotation fulcrum can be set to be large, and it can be extended in the vertical movement and contracted at the end of the movement to be accommodated in the storage section.

Further, of the first and second storage sections, at least the upper and lower corners of the front side of one of the storage sections are cut out, and at least the upper and lower corners of the rear side of the other storage section are cut out. Even when the storage units are arranged close to each other in a limited space, the corners that intersect by rotation are cut out to form each storage unit without providing unnecessary space. The parts can be arranged.

Further, by providing a lifting operation means for moving the support member on the sliding support portion, it is possible to move up and down without operating the storage portion, so that the storage portion to be operated is at a high position. It is effective when it is.

Further, by providing a balancing means for reducing or canceling the rotation torque by the storage portion acting on the support member, the difference in the rotation torque can be reduced even when the weight balance of each storage portion is lost. A smooth turning operation can be performed.

Further, the supporting member is a single arm, and the attitude regulating means comprises a fixed wheel provided concentrically with the moving fulcrum and non-rotating, and a supporting fulcrum by the supporting members of the first and second storage portions. Each of the rotating wheels, which are concentrically rotated with each of the storage portions, and a belt that extends over these fixed wheels and each of the rotating wheels, can be configured by an unstable supporting state of a single arm supporting member. The inclination of the storage unit from the horizontal position is prevented by a structure in which the belt is connected between the non-rotating fixed wheel and the rotating wheel fixed to the storage unit, so that the storage unit maintains a constant posture regardless of the rotation angle of the storage unit. Can be regulated.

Further, by forming an electric motor connected to the support member or the connecting shaft, the ascending and descending torque can be reduced, or the ascending and descending can be performed by electric drive.

Further, the first and second storage sections are on a work table, and the lowered position of each storage section is a height corresponding to an eye level between the work table and the storage section that stores each storage section. With this configuration, a space that does not interfere with the work can be secured above the work table, and the lower position can be set to a position where it can be easily inserted and removed. As a result, the upper storage portion can be used effectively.

When the first storage section 61 is pulled out from the state shown in FIG. 4G and rotated in a direction opposite to the above operation, the second storage section 62 is lowered, and FIGS.
It is possible to return to the original arrangement position by the reverse operation of (a).

If the lower position is set to a height position at which articles can be easily taken in and out, for example, an eye level, the storage section at an upper position where it is difficult to put in and out can be moved to the lower position at any time. The above storage space, which is difficult to remove and can only be used as a mere storage space, can be effectively used by the above configuration.

In the above configuration, since each of the storage portions 61 and 62 is rotatably supported by one of the support fulcrums P ₁ and P ₂ by the support member 64, there is a possibility that the horizontal attitude may be inclined by the rotation angle. However, since the posture maintaining portions 71 and 72 are provided between the support fulcrums P ₁ and P ₂ and the rotation fulcrum O, a constant horizontal posture is always maintained regardless of the rotation angle.

2 is at the vertical position on the vertical line, the sliding support portion 65 is moved by the distance from the rotation fulcrum O of the support member 69 to the roller 78.
The shape is such that the distance from the rotation fulcrum O on the horizontal line at the position is the shortest. Therefore, when the support member 69 is rotated by the rotation of the first storage section 61, the movement of the roller 78 is guided by the rotation guide 77, and therefore, the rotation fulcrum O
Is horizontally moved on the sliding support portion 65, and the first sliding portion 61
The second storage section 62 is moved up and down with the rotation of.

In the construction of the above-mentioned lifting path regulating means, the provision of the rollers 78 and 79 and the rotation guide 80 as shown in FIG. 8 enables the rotation of each of the storage portions 61a and 62a.

I have. Both ends of the rotation guide 80 are open in the direction in which the storage portions 61a and 62a rotate. When the support member 81 is rotated by rotating the storage portions 61a and 62a in the directions indicated by arrows in FIG. The roller 78 on the side of the storage section 62a escapes from the upper opening of the rotation guide 80, and the first storage section 61
The roller 79 on the a side moves in the rotation guide 80 toward the center. With this operation, the second storage portion 62a rotates around the rotation fulcrum O, and the first storage portion 61a moves upward by the movement of the rotation fulcrum O within the sliding support portion 65. When the second storage portion 62a is further rotated, the roller 78 enters the rotation guide 80 from the lower opening portion of the rotation guide 80, and the second storage portion 62 is positioned at a position where the support member 81 is vertically oriented.
a is replaced with the lower position, and the first storage portion 61a is replaced with the upper position.

In each of the above-described configurations, the first housing 61
According to this configuration, the first storage unit 61a or the second storage unit 62a located at the upper position is pulled down by the reciprocating rotation of the first storage unit 61a or the second storage unit 62. The upper and lower positions can be exchanged by turning in one of the directions. Therefore, the rotation fulcrum O of this configuration is 36
It can be rotated to 0 degrees, and the direction of rotation is always the direction of pulling down the storage sections 61a, 62a, so that the switching operation can be performed easily.

In the case of this configuration, each of the storage portions 61a,
62a is formed by notching each corner as shown in the figure,
When rotating in one direction, both corners are prevented from contacting.

In the configuration described above, each of the storage sections 6
As shown in FIG. 9, a stop position restricting means for locking the rotation of the support member 82 is provided for stably stopping the positions of the support members 1 and 62 when they are located at the upper position and the lower position, respectively. Can be.

As shown in FIG. 9, the stop position regulating means attaches rollers 83, 83 to both ends of the support member 82, respectively, and supports the inner wall of the storage cabinet 63 as shown in FIG. Locking portions 84, 84 each having a recess are attached to the vertical position where the member 82 is stopped. When the storage portions 61 and 62 move up and down and move to the predetermined upper and lower positions, the rollers 83 and 83 at both ends of the support member 82 fit into the recesses of the locking portions 84 and 84, respectively. Stabilization.
In this stopped state, the rollers 83, 83 are turned into the respective locking portions 84, by applying an operation of rotating the first storage portion 61.
Since it is removed from the state of being fitted into the rod 84, there is no hindrance to the elevating operation. This stop position regulating means can be applied not only to the configuration shown in FIG. 9 but also to other configurations.

Further, as shown in FIG. 9, it is also possible to provide a lifting operation means for directly moving the support member 82 on the sliding support portion 65. The elevating operation means 85 includes a roller 86 that rotates in the sliding support portion 65 and a roller 8.
Moving plate 87 that pivotally supports 6 and connects to supporting member 82
And an operation lever 88 extending from the pivotal position of the roller 86 of the moving plate 87 toward the door 63 a of the storage cabinet 63. In this configuration, when the operation lever 88 is pulled, the moving plate 87 moves on the sliding support portion 65 by the rotation of the roller 86, and moves the rotation fulcrum O of the connected support member 82 horizontally on the sliding support portion 65. Move. Due to the horizontal movement of the rotation fulcrum O of the support member 82, one end of the support member 82 is rotated by the roller 78 and the rotation guide 77.
As a result, the first storage portion 62 supported at the other end is rotated, and the second storage portion 62 is lowered. This configuration is different from each of the storage sections 61 and 62.
When the arrangement position is relatively high, in particular, when the first storage section 61, which is the main body for ascending and descending, is at the upper position, it is easy to perform the ascending and descending operation by operating the operation lever 88 at the lower position. The lifting operation can be performed.

Further, as shown in FIG.
And a rotation fulcrum return means for automatically returning the rotation fulcrum O to the set predetermined position. In this configuration, doors 89a, 89b are provided on both sides of the storage cabinet 89.

It is urged from both sides so that the rotation fulcrum O of the support member 69 is located at the set predetermined position. Each storage section 6 by human power
When the rotating members 1a and 62a are rotated, the rotation fulcrum O moves on the sliding support portion 90 against the urging force of the springs 91 and 91 depending on the rotating direction, and the respective storage portions 61a and 62a can be switched upside down. . Even if the pressurization by human power is released before the turning upside down by the rotation reaches the predetermined position, the spring 91,
The rotation fulcrum O is automatically returned to the predetermined position by the urging of 91. The predetermined position is a position at which the respective storage portions 61 and 62 are arranged in the vertical position, but may be set at an arbitrary position.

Further, when a balancing means such as a rotary damper is connected to the connecting shaft 67 in each configuration, the lifting operation becomes difficult due to the difference in weight between the articles stored in the storage sections 61 and 62. It is possible to suppress a sharp descent when the side becomes the descent direction, and to perform a stable elevating operation. In addition, a motor may be connected to the connecting shaft 67 to provide auxiliary power for the elevating operation, or the elevating operation may be performed electrically.
