There is the one described in Japanese Patent No. 154610. As shown in FIG. 9, this device includes a storage cabinet 1, a storage shelf 2, and movable support arms 3 and 4 for raising and lowering the storage shelf 2, and a spring that applies a force to the movable support arm 3. 5 are installed. One end 6 of the spring 5 is installed on the storage cabinet 1 side, and the other end 7 is installed on the movable support arm 3. The storage shelves 2 can be moved downward by turning the movable support arms 3 and 4 as indicated by solid arrows, and the storage shelves 2 installed at a high place can be moved to a low position where they can be accessed and used. Further, the spring 5 acts to urge the pulled-down storage shelf 2 into the storage cabinet 1, which is the storage position, in a direction of lifting the storage shelf 2, thereby reducing the operation force when the storage shelf 2 is raised. 1 a is a door of the storage cabinet 1.

[0003]

However, in the conventional elevating device, the spring 5 is installed to reduce the operating force when the storage shelf 2 is raised, and although the operating force is somewhat reduced, the spring 5 is not used. An operator needs to move the storage shelf 2 by hand until the shelf 2 is stored in the storage cabinet 1. For this reason, there has been a problem that a troublesome operation of pulling down the storage shelf and raising the storage shelf 2 after taking in and out of the stored items occurs. Further, although the operation force for raising the storage shelf 2 is reduced, it is necessary to apply a force until the storage shelf 2 is stored, and when the weight of the stored items increases, the operation force increases significantly. For this reason, the lifting operation may be particularly difficult for women, the elderly and the like. This problem is greater when the storage shelves 2 are installed at a high place.

[0004]

In order to solve the above-mentioned problems, the present invention comprises a driven body housed in a predetermined position, and a lifting mechanism for raising and lowering the driven body from a predetermined position. In particular, there is provided a drive unit for driving the driven body to the opposite side to the direction, particularly for moving the driven body to a predetermined position by itself.

[0005] According to the above invention, the driving unit can move the driven body to the predetermined position (storage position) by itself, and inconvenience of manually moving the driven body to the storage position during the ascent operation. Does not occur. Further, since the worker does not need to move the driven body by hand, no operation force for raising is generated.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the configuration described in each claim can be adopted as an embodiment. That is, claim 1
As described in the above, the driven body housed in a predetermined position, an elevating mechanism for raising and lowering the driven body from the predetermined position, and driving the driven body in a direction opposite to the direction of gravity via the elevating mechanism Sometimes, by providing a drive unit that moves the driven body to the predetermined position by itself, the drive unit can move the driven body to the predetermined storage position by itself, There is no need to move the body to the storage position by hand. Further, since the worker does not need to move the driven body by hand, no operation force for raising is generated.

In the lifting device according to a second aspect of the present invention, the driving portion has a driving force accumulated when the driven body is moved in the direction of gravity, and the accumulated driving force moves to the opposite side to the direction of gravity. When driven, the driven body is moved to the predetermined position by itself.

Although the driven body is moved by the weight of the operator in the direction of gravity, the force is easily applied in the moving direction, that is, in the downward direction, so that the driving force can be easily accumulated.

In the lifting device according to a third aspect of the present invention, the predetermined maximum load amount of the driven body is set such that the driven body is opposed to the direction of gravity when the load is mounted on the driven body. When the driven body is driven to the side, the value is set to a value equal to or less than the limit of the load capacity at which the driven body can move to a predetermined position by itself.

With this, if the load is equal to or less than a predetermined maximum load of the driven body, the driven body can be moved to a predetermined position by itself even when the load is mounted. With the above loading capacity, it cannot be moved on its own. However, the driving force of the driving unit acts as a force for energizing the lifting operation, and the operator needs to manually move the driven body to a predetermined storage position, but the lifting operation of the driven body is performed with a small operation force. It can be carried out.

Further, in the lifting device according to the fifth aspect of the present invention, the driving portion is constituted by an elastic means such as a spring or a gas spring. When an elastic means such as a spring is used, the driving force can be accumulated by extending or compressing the elastic means when the driven body descends, and the driving force can be generated by repulsion when the driven body rises. Can be achieved.

According to a sixth aspect of the present invention, the lifting device includes a driving unit constituted by a weight. Using a weight increases the potential energy when the driven body descends,
When ascending, this potential energy can be used to generate a driving force, and the object can be achieved with a simple configuration.

The lifting device according to a seventh aspect of the present invention is provided with a buffer means such as a hydraulic damper which exerts a braking force on the movement of the driven body, and the driven body moves rapidly. This can prevent the load from falling or falling, and can enhance the safety of the lifting operation. Also,
Since the moving speed of the driven body is reduced, the impact applied to the device itself is reduced, which leads to improvement in the durability and reliability of the device.

The lifting device according to an eighth aspect of the present invention is provided with a buffer means such as a hydraulic damper for buffering a driving force of a driving unit for driving the driven body. Provides a cushioning effect when the object is moved to a predetermined position by itself. In addition, when the loading amount is small, it is possible to prevent the moving speed from increasing, so that the loaded object can be prevented from falling or falling, and the safety of the lifting operation can be improved.

According to a ninth aspect of the present invention, there is provided an elevating device including an interlocking member for installing a driving unit, a shock absorber, etc., interlocked with the elevating mechanism, and the interlocking member is different from the elevating mechanism. By performing the operation, the operation characteristics of the driving force of the driving unit and the buffering force of the buffering device can be changed, and any characteristics can be obtained.

[0023]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a schematic side view of a lifting apparatus according to Embodiment 1 of the present invention.

In FIG. 1, a driven body 8 such as a storage container or a shelf is supported on a support substrate 10 such as a storage cabinet by an elevating mechanism 9. The elevating mechanism 9 is composed of two rotating arms 11 and 12 forming a parallel link, and pivots 13 and 1 are provided.
At 4, it is pivotally supported by the support substrate 10, and at pivots 15 and 16, it is pivotally supported by the driven body 8. In addition, a tension spring (elastic means) 17 as a driving unit is installed, and one end 18 of the fulcrum is on the rotary arm 12 and the other end 19 is the support substrate 1.
Installed on the 0 side. The extension spring 17 stores a driving force when moving the driven body 8 in the direction of gravity up to the position of arrow B, and moves the driven body 8 to the predetermined position A when driving the driven body 8 in the direction opposite to the direction of gravity with the stored driving force. Is moved to the inside of the support substrate 10 by itself. A rotary damper 20 is provided for the rotation of the pivot 13 as a shock absorber for applying a braking force to the movement of the driven body 8, that is, the turning of the rotary arm 11. Also,
A lock mechanism 21 for locking the driven body 8 at predetermined positions A and B is provided. That is, the lock mechanism 21 is detachably engaged with the concave portions 12a and 12b provided at the other end of the rotary arm 12, and locks the driven body 8 at the positions A and B.

Next, the operation and operation will be described. The lock of the lock mechanism 21 is released, the driven body 8 is pulled out from the position A to the position B, and is moved by the drive unit 17 in the opposite direction. That is, the driven body 8 is rotated by the rotation of the lifting mechanism 9.
Is driven up and down, but the driven body 8 moves while maintaining a substantially horizontal position because the lifting mechanism 9 has a parallel link configuration. Then, a tension spring 17 installed on the rotating arm 12 is provided.
When the driven body 8 is extended in moving in the direction of gravity (downward), the driving force is accumulated by moving the driven body 8 in the direction of gravity (downward). By simply removing, the driven body 8 is driven by itself to the storage position (predetermined position) A by the driving force (accumulation force). For example, it is assumed that the driving unit 17 is configured to be able to drive to a predetermined position A by itself even when a 12 kg load is mounted on the driven body 8. At this time, if the maximum loading capacity of the lifting device is 10 kg, the driving unit 17 can drive the driven body 8 from the position B to the position A by itself even in the maximum loading state. In this example, the moment by the tension spring and the moment on the load side at the time of maximum loading are in a relationship as shown in FIG. 2 (however, the value of the moment is made dimensionless so as to match the value of the loading load). The moment from the tension spring 17 is greater in the entire range from the state B pulled out (0 °) to the storage state A (100 °), and it can be seen that the driven body 8 can be moved from B to A by itself. Therefore, the operator does not need to manually move the driven body 8 from the position B to the storage position A when the driven body 8 is lifted, and it is troublesome to store the driven body 8 after loading and unloading the load. No work occurs. In addition, since there is no operation force to push up the driven body 8 during the ascent operation, even a woman or an elderly person can easily use it. In particular, since the elevating type storage device is often installed at a high place, it can be used easily and safely even when it is difficult to reach.

The locking means 21 locks the driven body 8 at an arbitrary position.
Are locked at the positions A and B in FIG.
In the pulled-out state B, the tension spring 17 applies an upward force to the driven body 8, but can be fixed by the lock mechanism 21, and the load can be easily taken in and out in the state B. If this lock mechanism 21 is released,
As described above, the tension spring 17 moves the driven body 8 to the retracted state A by itself.

The relationship between the position of the rotary arm 12 and the position of the tension spring 17 as shown in FIG. 1 acts as an operation force reducing mechanism. In this case, the moment due to the driving force of the tension spring 17 has the characteristics shown in FIG. 2, and the driven body 8 can be lowered with a force of 12 kg even when the load is empty. However, the torsion spring 2 shown in FIG.
In order to move a load of 12 kg to a predetermined position A by itself with a configuration in which
The moment due to the driving force of the torsion spring 22 is as shown in FIG. 4, and when empty, a force of 17 kg at the maximum is required. In other words, a very large force is required when pulling down. On the other hand, the configuration of FIG. 1 (the positional relationship between the rotation arm 12 and the extension spring 17) acts as an operating force reducing mechanism for reducing the force required to move the driven body 8 in the direction of gravity. The pull-down operation can be performed with the operation force.

A rotary damper 20 as a buffering means is installed so as to act on the turning of the rotary arm 11 and acts to buffer the driving force of the tension spring 17. Thereby, it is possible to suppress the driven body 8 from rising rapidly, to prevent the load from falling or falling, and to enhance safety in use.

The buffering means 20 acts not only in the direction of absorbing the driving force of the driving section (tension spring) 17 (upward) but also in the case of moving the driven body 8 downward. In this case, even when a load greater than the maximum load capacity is mounted, the driven body 8 can be prevented from dropping rapidly, and safety can be ensured even in abnormal use. Note that a single shock absorber that exerts a shock absorbing force in the vertical direction may be used, or a single-effect shock absorbing means in the vertical direction may be provided.

The maximum load capacity of the driven body 8 is determined in advance when the driven body 8 is driven in the direction opposite to the direction of gravity in a state where the load is mounted on the driven body 8. If the load capacity is equal to or more than the limit load capacity that can be moved by itself to the predetermined position A, for example, if the maximum load capacity of the apparatus is 15 kg in the above example, the relationship between the moments is as shown in FIG.
become that way. If the load amount is 12 kg or less, the drive unit 17 can move the driven body 8 to the predetermined storage position A by itself, but cannot move between 12 kg and 15 kg.
In other words, if the load is 12 kg or less, the same operation and effect as described above can be obtained, but if it is not larger, it cannot be obtained. However, even if the load capacity is 12 kg or more, the driving unit 1
Since the driving force by 7 acts as a force for intensifying the lifting operation, the operator needs to move the driven body 8 to the storage position A by hand, but the lifting operation of the driven body 8 is performed with a very small operation force. It can be performed.

Here, the tension spring 17 is used as the driving unit, but an elastic body such as a compression spring, a gas spring, or rubber may be used. Further, instead of the elastic means, a means such as a weight may be used. Further, the tension spring 17 as the driving unit is directly installed on the rotary arm 12 as the elevating mechanism, but a member interlocked with the elevating mechanism 9 may be provided, and the driving unit may be provided on the member to apply the driving force. In this case, the direction in which the driving force acts can be changed, and the characteristics of the moment can be easily changed.

In the example of FIG. 1, the damping means is a rotary damper 20, but it may be a direct acting type, or may be of any structure such as a hydraulic type or a friction type.

Also, the lock mechanism 21 is shown as an example of a mechanical type in FIG. 1, but may be of an electric type such as various electromagnetic forces. The part for releasing the lock may be formed by any means.

The elevating mechanism 9 may be installed on both the left and right sides of the driven body 8, or only one of them.
Further, the configuration may be such that it is installed not only on the side surface of the driven body 8 but also on the back and bottom.

(Embodiment 2) FIG. 6 is a schematic side view of an elevating device according to Embodiment 2 of the present invention. The same reference numerals are given to the same components as those of Embodiment 1 shown in FIG. The description will be omitted, and different points will be mainly described.

The structure is almost the same as that of the first embodiment, except that a weight 23 is provided as a drive unit and a direct-acting hydraulic damper 24 is used as a buffer. An interlocking member 25 interlocked with the rotating arm 12 is installed, and a rope and a hydraulic damper that suspend the weight 23 are installed in the interlocking member.

The operation and effect are the same as in the first embodiment. When the interlocking member 25 is used, the direction in which the driving force acts can be changed, and the characteristics of the moment can be easily changed.

(Embodiment 3) FIG. 7 is a schematic side view of an elevating device according to Embodiment 3 of the present invention. The same components as those in Embodiment 1 shown in FIG. The description will be omitted, and different points will be mainly described.

This is an example of a device for moving the driven body 8 in the vertical direction.

Certain vertical conversion engagement part 27
And a vertical conversion guide groove 28 fitted in the driven body 8.

The operation and effect of the drive unit 17 are the same as those of the first embodiment, but the movement of the driven body 8 is limited by the slide device 26 in the vertical direction (directions of arrows A and B). The driving force of the tension spring 17 acting on the driven body 8 is transmitted to the driven body 8 via the vertical conversion engagement portion 27 and the vertical conversion guide groove 28. With this driving force, the driven body 8 moves from B to the stored state of A by itself.

In this example, the driving force is transmitted to the driven body 8 via the rotating arm 12, but this is used as an operating force reducing mechanism, and even if the rotating arm 12 is not used. I don't care. For example, a driving unit 17 such as a spring may be directly installed on the driven body 8.

Although the tension spring 17 is used as the driving unit, a driving unit such as a compression spring, a gas spring, or a weight may be used as in the first embodiment.

(Embodiment 4) FIG. 8 is a schematic perspective view of an elevating device according to Embodiment 4 of the present invention. The same components as those of Embodiment 1 shown in FIG. The description will be omitted, and different points will be mainly described.

In the fourth embodiment, the elevating mechanism 9 is provided on both the left and right sides of the driven body 8, and the interlocking means 29, which is a left and right connecting means for interlocking the movement of the left and right elevating mechanisms 9, is connected to the pivot 13 Installed nearby. The cubic boxes provided on both sides of the driven body 8 correspond to the portions indicated by broken lines in FIG.

The operation and operation and effect are the same as those of the first embodiment.
Since the operations of the (rotating arms 11, 12) are synchronized,
The right and left elevating mechanisms 9 are not kinked, and the operation of the driven body 8 can be performed smoothly.
