Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multi-stage parking device used in a parking lot.

[Conventional technology]

2. Description of the Related Art In order to effectively utilize narrow parking spaces, multi-level parking devices are known that allow vehicles to be parked in two or three levels vertically. Furthermore, some parking devices of this type are capable of parking vehicles in a plurality of rows in each of the longitudinal direction (front-rear direction of the vehicle) and the left-right direction (vehicle width direction).

Although such two-tier or three-tier parking systems capable of parking multiple rows of vehicles in the front-rear direction have the advantage of accommodating a large number of vehicles in a relatively narrow parking space, they also have various problems.

For example, if there is a parked vehicle in the front row, it is impossible for a vehicle in the rear row to enter or exit the vehicle unless this vehicle is moved. Therefore, some measure must be taken to move the vehicles in the front row.
For example, it is possible to configure the pallet carrying the front row of vehicles to be movable laterally, but if the front row is a pit type (vertical hole type) parking system, if the pallet on the front row side is not empty, the pallet on the front row side can be moved laterally. It is not possible to use pallets to move cars in the back row in and out. Furthermore, the pit-type parking device has a hole for at least one vehicle at floor level in order to take the vehicle placed on the lower pallet into and out of the pit. Therefore, there is a safety problem.

Regarding this point, a parking device may be considered in which a plurality of ceiling plates are provided between a plurality of above-ground parking pallets to seal the distance between the pallets, as in the prior art disclosed in Utility Model Application Publication No. 59-138667. ing.

[Problem that the invention seeks to solve]

However, in the above-mentioned prior art, as the number of above-ground parking pallets increases, it is necessary to increase the number of ceiling panels accordingly, which not only requires a large number of components, but also requires a large number of devices and electric circuits to drive each ceiling panel. etc. become complicated, making it difficult to control the ceiling board.

Moreover, in the above prior art, when the upper surface of the ceiling plate is used as a vehicle passageway, a plurality of ceiling plates are placed next to each other so that vehicles can pass over it, so the load is unevenly distributed on each ceiling plate when vehicles pass. This is dangerous because the load balance on the rollers that support the ceiling panel is likely to be lost.

[Means for solving problems]

The parking device of the present invention includes a pallet guide rail arranged laterally, and is arranged so as to be able to move laterally along the guide rail. A horizontal pallet is provided in such a number as to create a vacant space for approximately one sheet at one location, and a single pallet is arranged in the horizontal row direction near the horizontal pallet on the lower surface side of the horizontal pallet and fills the vacant space. an auxiliary traversing pallet that has sufficient space to block the auxiliary traversing pallet and is movable along the guide rail over the entire lateral area in which the traversing pallet can move; and an upper pallet that is arranged above the lower pallet so as to be movable up and down, has a width narrower than the auxiliary traverse pallet, and rides on the auxiliary traverse pallet in a lowered state. be.

[Effect]

As will be described in detail in the embodiment below, the parking device of the present invention, for example, when a vehicle in the rear row enters or exits, if there is no vehicle on the transverse pallet on the front row side, the parking device climbs over the transverse pallet to allow the vehicle in the rear row to enter or exit. can be done. If there is a vehicle on this front pallet, move the front pallet laterally to a position where it does not obstruct the passage of vehicles in the rear row, and replace it with an auxiliary traversing pallet to a position that will be a passage for vehicles in the rear row. to close the top opening of the pit. In this way, vehicles in the rear row can enter and exit by climbing over the auxiliary traversing pallet.

Since only one auxiliary traversing pallet forms a vehicle path, by allowing the vehicle to pass over this pallet, it is possible to avoid losing the balance of the auxiliary traversing pallet when a vehicle passes.

In addition, in order to take out a vehicle placed on the lower pallet in the pit, the transverse pallet and the auxiliary transverse pallet are retracted laterally so that the upper part of the pallet is open, and the lower pallet is raised. The lower pallet is raised to almost the height of the entrance/exit surface, and the vehicles on this pallet can leave the garage. When leaving the garage, if a vehicle is parked in the front row, the vehicle in the front row is moved laterally as described above, and then the vehicle in the rear row is left. The vehicle on the upper pallet becomes ready to leave the garage by lowering the upper pallet. Since the upper pallet is always in a suspended state, it is desired that it be small in size, and in addition, it is desired that it be narrow in width in order to reduce the deviation of the weight from side to side when a vehicle is placed on it. Even if such a small narrow upper pallet is used, this upper pallet overlaps the wide auxiliary traversing pallet when lowered, so there is a dangerous gap between the pallet and the side leading into the pit. This can be avoided. Stocking can be carried out in the reverse order to the above.

〔Example〕

In one embodiment shown in FIGS. 1 to 8, a pit 1 is constructed in the parking lot, and a frame 2 is built on the pit 1.
On the upper edge of the pit 1, there are two
Book pallet guide rails 3, 4 are arranged laterally. For example, the guide rails 3 and 4 have H
Shaped steel etc. are used.

Along the guide rails 3 and 4, two or more (in the case of three pallets in the figure) transverse pallets 6 are provided. As shown in FIG. 1, rollers 8 for rolling are attached to each of the traversing pallets 6 and rolling on guide rails 3 and 4. As shown in FIG. These rollers 8 are rotated by a motor 9 built into the traversing pallet 6, so that they can run laterally along the guide rails 3, 4.

As shown in FIG. 4 or 6, these multiple horizontal pallets 6
The number of guide rails 3 and 4 is less than the length of the guide rails 3 and 4 so that an empty space 11 corresponding to approximately one pallet is provided at each location. A convex portion 13 (see FIG. 1) is provided on the upper surface of the traversing pallet 6, which serves as a guide for the stopping position of the vehicle. The height of the convex portion 13 is lower than that of a normal stopper so that a vehicle can pass over the pallet 6 in either the front or rear direction.

Further, on the lower surface side of the traversing pallet 6, an auxiliary traversing pallet 15 is arranged close to the pallet 6. This pallet 15 also has rollers 17 for running, and each roller 17 is in rolling contact with an intermediate portion in the vertical direction of the guide rails 3, 4 so as to be movable laterally. This roller 17 is rotated by a motor 18 built into the auxiliary traversing pallet 15. As the rollers 17 rotate, the auxiliary traverse pallet 15 travels laterally along the guide rails 3 and 4. The range in which the auxiliary traversing pallet 15 can move laterally extends over the entire range in which the traversing pallet 6 can move.

This auxiliary transverse pallet 15 has a sufficient width to substantially block the empty space 11,
Except when raising the lower pallet 30, which will be described later, the position is controlled by a controller (not shown) so that the lower pallet 30 is moved to a position that closes the empty space 11, that is, the upper opening of the pit. The upper surface of the auxiliary traverse pallet 15 is substantially flat so that vehicles can pass through it in either the forward or backward direction. In each figure after FIG. 4, the auxiliary transverse pallet 15 is shown by hatching for easy understanding.

On the other hand, in the frame 2, a plurality of sheets are placed in the horizontal direction (in the case of four sheets in the figure), located above the horizontal pallet 6.
An upper pallet 20 is arranged. These upper pallets 20 are driven by a drive mechanism 2 shown in FIG.
1, it is provided so as to be movable up and down from the upper stage position to the middle stage position (approximately the height of the entrance/exit surface). The drive mechanism 21 suspends the upper pallet 20 by a hanging member 23 such as a wire or chain, and also connects the hanging member 23 to a motor 2.
5, the pallet 20 is moved up and down.

Further, within the pit 1, a vehicle storage space 27 having a height sufficient to accommodate a vehicle is formed below the auxiliary traveling pallet 15. In this space 27, a plurality of lower pallets 30 (in the case of four pallets in the figure) are arranged laterally. These lower pallets 30
is provided so as to be movable up and down by a drive mechanism 31 shown in FIG. This drive mechanism 31 is
The lower pallet 30 is suspended by a hanging member 33 such as a wire or a chain, and this hanging member 33 is driven by a motor 35 to move the pallet 30 up and down.

The four types of palettes mentioned above 6, 15, 20, 3
0 has a size that can accommodate a vehicle,
Moreover, as shown by the arrows in FIG. 4, they are each movable vertically or horizontally independently of each other. As shown in FIG. 5, a plurality of rows (three rows in the figure) of devices having the same configuration are provided in the longitudinal direction (the longitudinal direction of the vehicle). In FIG. 5, the left side of the drawing is the entrance to the parking lot.

Next, the operation of the pit-type three-stage parallel parking system configured as described above will be explained.

For example, in Figures 4 and 5, if you want to leave the vehicle _C1 located on the upper left side of the last row,
When vehicle C ₂ is parked on that side, first move the transverse pallet 6 on which vehicle C ₂ is placed laterally, as shown in FIG. Then, the auxiliary traversing pallet 15 is moved to the left side in the figure to close the upper opening of the pit, that is, the empty space 11.

Next, the upper pallet 20 on which the vehicle _C1 is placed is lowered (FIG. 7), and the vehicle _C1 is lowered to the level of the entrance/exit surface. Upper pallet 20 is horizontal pallet 6
Although it is smaller than the upper pallet 20, since the auxiliary transverse pallet 15 with a wide area overlaps directly below the upper pallet 20, there is no danger of creating a dangerous gap around the upper pallet 20. When the vehicle _C1 is lowered to the height of the entry/exit surface, if there is no parked vehicle in the front row, the vehicle will climb over the transverse pallet 6 or the auxiliary transverse pallet 15 in the front row.
C ₁ can be issued.

At this time, if there is a parked vehicle in the front row, the transverse pallet 6 on which this vehicle is riding is moved laterally to a position where it does not obstruct the passage of vehicles in the rear row, and the auxiliary transverse pallet 1 is placed in its place.
5 is moved to a position that becomes a passage for vehicles in the rear row to close up the empty space 11. In this way, vehicles in the rear row can enter and exit by climbing over the auxiliary transverse pallet 15.

On the other hand, vehicle C ₃ on the lower pallet 30
In order to take the vehicle out of the warehouse, as shown in FIG. 8, the transverse pallet 6 and the auxiliary transverse pallet 15 are retracted laterally so that the upper part of the lower pallet 30 is opened, and the lower pallet 30 is moved between the vehicle C3 and the vehicle _C3 . By raising them together, the vehicle _C3 on the pallet 30 is raised to the level of the entrance/exit surface and can be taken out. When leaving the garage, if there is a parked vehicle in the front row, the vehicle in the front row is moved laterally as described above, and then the vehicle _C3 in the back row is let out.

The series of operations described above are automatically performed based on a predetermined program stored in the controller in advance by pressing the operation switch of the corresponding palette on the operation panel (not shown). In the case of warehousing, the procedure is the reverse of the warehousing procedure.

The parking device of the above embodiment has three stages and three vertical
Although there are four columns and four rows, the number of vertical and horizontal columns is not limited to the number in the embodiment, as it is sufficient to have a plurality of columns. Further, the present invention can also be applied to a two-stage parking device in which the frame 2 and the upper pallet 20 are omitted.
That is, in this case, the above-mentioned horizontal pallet 6
, an auxiliary transverse pallet 15 and a lower pallet 30 in the pit.

Furthermore, as shown in FIG.
The same number as 0 and 30 may be provided, or
Alternatively, as shown in FIG. 11, the number of transverse pallets 6 may be greater than the number of upper and lower pallets 20, 30. In this case, a dead space S such as the back side of a pillar inside a building can be effectively used.

〔Effect of the invention〕

According to the present invention, the upper surface opening of the pit can be closed using the transverse pallet and the auxiliary transverse pallet, and the road and passage for passengers can be secured. Vehicles can be taken in and out from the side. Since only one auxiliary traverse pallet forms the vehicle path, the balance of the pallet will not be significantly disturbed even if a vehicle passes over it. Therefore, even if there are a large number of columns or rows, vehicles at any position can be easily taken in and taken out. In addition, the top opening of the pit can be kept closed at all times, and even if a small, narrow upper pallet is used, when the upper pallet descends, it will rest on the wide auxiliary traversing pallet. Therefore, it is possible to avoid creating a dangerous gap next to the upper pallet, which is preferable in terms of safety. Furthermore, since there is only one horizontal pallet in the row direction, the number of members can be reduced, and the electric circuit and position control of the pallet can be easily controlled.
