Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a three-dimensional hangar that can store objects such as a large number of bicycles and logs for cultivating shiitake mushrooms in a space-efficient manner. This relates to a three-dimensional hangar that is variable between the upper and lower floors.

In ordinary multi-story hangars, each floor is often of the same height. However, although the floors where stored items are stored and retrieved are required to have a predetermined height, the floors that do not receive and retrieve stored items do not necessarily have to have the same height, and only need to be as high as the stored items.
Therefore, making the heights of each floor the same may waste storage space depending on the objects to be stored, reducing storage efficiency.

Conventionally, as a three-dimensional hangar where the height of each floor is variable, the stage on the top floor is suspended with wire ropes etc. using a hoist installed at the top of the building, and two types of lengths are installed between each stage, long and short. A structure has been proposed in which the stage on the first floor is suspended by the longer link, and the stages on the second and higher floors are suspended by switching to the shorter link. However, with this structure, switching between long and short links is extremely complicated, resulting in a lack of reliability and safety.Furthermore, since the hoisting machine is located at the top, the building becomes taller.

The present invention provides a three-dimensional hangar that can eliminate these drawbacks and greatly improve storage efficiency.

The three-dimensional hangar of the present invention that solves this problem includes a plurality of horizontal stages arranged vertically that can be raised and lowered between a stage storage area and an article storage area above it, and vertical stages between each adjacent stage. An upper link whose base end is swingably connected to an upper stage, and whose base end is swingably connected to a lower stage, and whose distal end is connected to the upper link through a long hole so that the interval can be changed freely. The connection point between the lower link connected to the upper link of the lower link connected to each stage located on a specific floor and the upper floor in the article storage area, and the lower link with its tip end connected to the upper stage. A guide member that guides the stage so that it can be slid up and down while being held in a position where it is received and supported, and a lift that moves up and down between the stage storage area and a specific floor by detachably holding each stage. The device includes a stage support that supports each stage on a specific floor and whose supported state is released in conjunction with the operation of the lifting device.

According to this configuration, in the article storage area,
Each stage located on a floor above a specific floor is received and supported by the stage immediately below it via a lower link, and each stage located on a floor below a specific floor is supported by the upper and lower links to the stage immediately above it. The stage interval, that is, the article storage height can be made different between upper and lower floors than a specific floor.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, the building 1 is capable of dividing an article storage area, which is an internal space above the ground, into a plurality of floors, and has a door 2 at the entrance on the first floor. A pit 3 is excavated in the basement, and stages 10 of the same number as the number of floors of the building 1 are stacked vertically and stored in a stage storage area inside the pit 3. At this time, the top surface of the first stage 10 from the top is set to be exactly at the same height as the floor surface of the first floor.

As shown in FIGS. 1 to 5, the stage 10 is a horizontal rectangular plate-like body that accommodates a plurality of stored objects (not shown) on its upper surface, and the stage 10 is a horizontal rectangular plate-shaped body that accommodates a plurality of objects (not shown) on its upper surface. guide rail 12
Go up and down along the The guide rail 12 is connected to the building 1
It is vertically fixed to the building 1 from the top floor to the bottom of the pit 3.

In stages 10 that are vertically adjacent to each other, the base end of the upper link 14 is connected to the side surface of the upper stage 10 via a pin 13, and the base end of the lower link 16 is connected to the side surface of the lower stage 10 via a pin 15. Each of the lower links 16 is pivotably attached, and the distal end of the lower link 16 is movably connected to a pin 18 that slides through a long hole 17 formed at the distal end of the upper link 14. In this way, each stage 1
Connect between 0's. At this time, as shown in Figure 1,
The distance L between the pins 13 facing each other on the left and right sides is set to be slightly smaller than the distance M between the pins 15. In addition, as described later, the length of the lower link 16 is such that the interval between the upper and lower stages corresponds to the storage height of the stored object, and the length of the upper and lower links 14 and 16 is such that the interval between the upper and lower stages corresponds to the storage height of the stored object. The height should be set at an appropriate height for entering and exiting the warehouse.

The upper and lower links 14 and 16 of the stages 10 housed inside the pit 3 are folded up at pins 18, allowing the stages 10 to be stacked. A stopper 19 is fixed to the side surface of the stage 10 to hold the lower link 16 in the folded state.

Guide member 20 having a groove 21 extending linearly
is fixed vertically to the building 1 from the top floor to the middle of the second floor and the first floor. One side 22 of the groove 21
The lower end portion is curved in a direction away from the other side, and the lower end portion of the groove 21 forms a flap-shaped opening 23 that widens downward. Further, a guide roller 24 is rotatably attached to the end of the pin 18, and enters the groove 21 through the opening 23 of the guide member 20 and rolls along the groove 21 as the stage 10 rises. That is, as shown in FIGS. 3 and 4, the guide member 20 is directed to a specific floor (the second floor in this embodiment).
and the connecting point 18 of the lower link 16 connected to each stage 10 located on the upper floor with the upper link 17, so that the lower link 16 is in an upright position where its tip receives and supports the upper stage 10. It is configured to be guided so as to be slidable up and down while being held.

The lifting device 30 is arranged close to the four corners of the stage 10 inside the pit 3, as shown in FIGS. 1, 6, and 7. The threaded rod 31 is a vertical rod-shaped body with a male thread carved into the entire length, and its upper end is connected to the building 1.
A guide 37 is rotatably supported by a bearing 32 at the upper end thereof, and a gearbox 33 is attached at the lower end.
It is connected to the. The gearbox 33 is connected to a motor 35 via a drive shaft 34. Further, an elevating body 36 is provided to be movable up and down along a guide 37 fixed to the frame of the building 1, and a nut 38 is fixed to the lower end surface of the elevating body 36. The threaded rod 31
is freely movably passed through a hole drilled in the center of the elevating body 36 and is screwed into the nut 38. Note that the lifting stroke of the elevating body 36 may be sufficient as long as it is sufficient to move the stage 10 up and down between the stage storage area and the second floor, which is the specific floor. Further, a guide roller 39 is rotatably disposed on the elevating body 36 as appropriate, so that the elevating body 36 can be smoothly raised and lowered.

As shown in FIGS. 6 and 7, the auxiliary support 40 consists of an operating cylinder 41 and a bell crank-shaped stage support 42. The operating cylinder 41 may be of any hydraulic, pneumatic, or electric type, and is pivotably attached to the upper end surface of the elevating body 36, and the tip of the piston rod is pivotably attached to the side surface of the elevating body 36. It is rotatably connected to one end of one lever 43 of the stage support 42 . Working cylinder 41
operates in conjunction with the lifting device, and the other lever 44 of the stage support 42 removably engages with the lower surface of the stage 10 to support it.

As shown in FIGS. 8 and 9, the stage support 50 consists of an operating cylinder 51 and a bell crank-shaped stage support 52. The operating cylinder 51 may be of hydraulic, pneumatic or electric type, and
The tip of the piston rod is rotatably connected to one end of a lever 53 of a stage support 52, which is pivotally attached to the frame of the building 1. The operating cylinder 51 operates in conjunction with the lifting device, and the other lever 54 of the stage support 52 removably engages with and supports the lower surface of the stage 10 on the second floor, which is a specific floor. The stage 10 supported on the second floor by the stage support 50 suspends and supports the stage 10 on the first floor via upper and lower links 14 and 16. At this time, the pin 18 is locked to the lower end of the elongated hole 17, and the vertical distance between the stages 10, 10 is maximized.

The three-dimensional hangar of the present invention is configured as described above, and the storage and removal of stored items is performed as follows.

First, open door 2 of the entrance/exit. Since the upper surface of the first stage 10 from the top is at the same height as the floor surface of the first floor, objects to be stored are stored thereon. For safety reasons, it is preferable that the door 2 be linked with the elevating device so that it does not open unless one of the stages 10 is stopped on the first floor.

When the first stage 10 is full of objects to be stored, the door 2 is closed, the actuating cylinder 41 of the auxiliary support 40 is actuated, and the lever 44 of the stage support 42 is engaged with the lower surface of the first stage 10. , motor 3
5 in the upward direction. Power is transmitted to the gearbox 33 via the drive shaft 34 and rotates the threaded rod 31. The threaded rod 31 causes the elevating body 36 to rise along the guide 37 by screwing with the nut 38 . Along with this, the first stage 10 also rises, and when it reaches the second floor, the motor 35 is stopped. At this time, the upper and lower links 14 and 16 of the first stage 10 extend linearly to suspend the second stage 10 exactly at the first floor.
The lengths of the upper and lower links 14 and 16 are set so that the vertical distance between the stages 10 on the first and second floors is at an appropriate height to allow storage and removal of stored items. next,
The actuation cylinder 51 of the stage support 50 is actuated to engage the lever 54 of the stage support 52 with the lower surface of the first stage 10 to support it, and at the same time, the engagement of the auxiliary support 40 is released, and the motor 3
5 to lower the elevating body 36 to the pit 3. The door 2 is opened and the object to be stored is stored on the upper surface of the second stage 10.

When the second stage 10 is full of objects to be stored, the door 2 is closed and the motor 35 is operated to raise and lower the elevating body 3.
6 to the first floor. Stage 1 of the first stage
The second stage 10 is supported by the auxiliary support 40 and the motor 35 is operated to ascend to the second floor in the same manner as in the case of stage 0. At this time, the 1st and 2nd stage
The pin 18 between the stages 10 is connected to the opening 2 of the guide member 20 via the guide roller 24.
3 enters the groove 21 and rises, so the lower link 1
6 also stands upright and rises. At the same time, the pin 18 slides along the elongated hole 17 of the upper link 14, and the upper link 14 gradually becomes inclined with respect to the lower link 16. The lower link 16 continues to rise, and when its upper end comes into contact with the lower surface of the first stage 10, it supports the first stage and causes it to rise together. Since the stage support 50 is disengaged from the first stage 10, it returns to its original position.

When the second stage 10 reaches the second floor, the stage support 50 is operated to support the second stage 10, the auxiliary support 40 is disengaged, and the motor 35 is operated to move the elevating body 36. Descend to pit 3. Thus, the second stage 10 is located on the second floor, and the first stage 10 is located on the second floor.
is supported at exactly the third floor position, and the third stage 10 is suspended at exactly the first floor position. The storage height on the first floor is determined by the lengths of the upper and lower links 14 and 16 that can be extended as described above, and is an appropriate height for loading and unloading, whereas the storage height on the second floor is determined by the length of the lower links 16. Depends on the situation. The length of the lower link 16 is set so that the interval between the upper and lower stages corresponds to the storage height of the stored object. The door 2 is opened and the object to be stored is stored on the upper surface of the third stage 10.

In this way, the objects to be stored are stored in the remaining stages 10 one after another.

It is clear that when taking out the stored items, the process can be performed in the opposite manner to the above. As shown in FIG. 1, the distance L between the pins 13 is slightly smaller than the distance M between the pins 15, so that the left and right upper and lower links 14 and 16 on the first floor form a figure eight shape. Therefore, when the empty stages 10 on the first floor are lowered into the pit 3, the upper and lower links 14 and 16 are naturally folded at the pins 18, and the stages 10 can be stacked. The stopper 19 holds the lower link 16 in the folded state.

There is no problem even if the distance L between the pins 13 is made equal to the distance M between the pins 15 and the left and right upper and lower links 14 and 16 are made vertical. However, in this case, appropriate means are provided to ensure that the upper and lower links 14, 16 can be folded in the same direction.

Further, in the three-dimensional hangar of the present invention, the specific floor is not limited to only the second floor as in the above embodiments, but it goes without saying that a desired floor can be specified depending on the purpose. In this case, it is sufficient to increase the travel of the lifting device to the specific floor and to provide a stage support at the specific floor.

In the three-dimensional hangar of the present invention configured as described above, the storage height of each floor above an arbitrarily specified floor can be reduced to the minimum level depending on the purpose, so the storage efficiency is extremely high. It has an excellent effect in that it can be used in a wide range of applications.
