Description

[Detailed explanation of the invention] (a) Purpose of the invention [Field of industrial application] This invention is intended for use in the field of mechanical parking devices, where a plurality of mechanical parking devices are arranged in tandem, This relates to a movable safety device for guiding and instructing whether a vehicle is in a good or bad stopping position.

[Prior Art] In the field of mechanical parking devices, a configuration in which a plurality of parking devices are arranged in tandem is known as a parallel parking device. It has come to be used frequently as it is suitable for narrow and long sites.

Figures 4A and 4B show a parallel parking system using the vertical circulation system. That is, in the parking device shaft 52, there are a first parking device 53a which is a front device and a second parking device 5 which is a rear device.
3b are arranged. First parking device 53a
The chains 54a, 54 are endlessly suspended in circulation.
A plurality of cages 55a, 5 to accommodate cars
5a is suspended, and the second parking device 53b is also suspended in an endless manner.
...was suspended. However, in this figure, only one cage 55a or 55b at the lowest position is shown. In this way, the cages 55a, 55a... are connected to the chains 54a, 54a, respectively.
The cages 55b, 55b, . . . circulate together with the chains 54b, 54b, and a desired cage is brought to the lowest position to allow the vehicle to enter or leave the garage.

Here, the first parking device 53a is a chain 54
Only at one place in the endless circulation connection of a and 54a,
A space 56 is formed in which the cage 55a is not disposed.

When entering the first parking device 53a, the vehicle enters from the entrance 58 in the direction of the arrow 58a as shown in FIG. 4A, and then enters the cage 55a. On the other hand, the second parking device 53b
When parking the vehicle, the first parking device 53a is rotated as shown in FIG. The car 55b is moved onto the floor 57a through a movable flap 59 for passing over the step, passes through the passage 57 in the direction of the arrow 58a, and enters the cage 55b. When leaving the warehouse, the reverse operation is performed.

Such a device is well known as an example of a two-parallel type parking device with a single entrance and exit in a vertical circulation system, and is often implemented.

[Problems to be solved by the invention] In such a device, the shutter or door in front of the entrance 58 is normally kept open during business hours, and when there is a demand for storage, the manager can Select and call an appropriate cage from either the parking device 53a or the second parking device 53b, and instruct the driver of the parked vehicle whether to enter the front or rear parking device. and have them enter. When such an operation is performed, if the car driver specifies to enter the second parking device 53b, the space 5
It reaches the cage 55b through the floor surface 57a of No. 6, thereby preventing misidentification. In addition, in this case, as in the case of a normal single-row parking device, a guide light is provided on the back wall to indicate forward and backward directions to correct the stopping position of the car, so that the correct stopping position can be determined. can be easily known. However, when the driver of the car specifies to enter the first parking device 53a, even if the driver enters the cage 55a through the entrance 58, there is a second parking device 53b located further back.
The cage 55b is visible in front of the car path,
Furthermore, since the guide light mentioned above is not provided, the driver may mistakenly think that he should enter the cage 55a further back.
Even if it does not result in a serious accident, it may cause damage to the car or cage, or it may take time to recover.

As a response to this problem, the first parking device 53a
A physical barrier such as a door is used between the parking device and the second parking device 53b to prevent entry to the rear side.

FIG. 5 shows a plan view of such a case. Here, double-opening doors 60, 60 are installed between the first parking device 53a and the second parking device 53b in the parking device shaft 52, and the doors shown by solid lines in FIG. The positions 60a and 60a of the doors 60 and 60 indicate the closed state, and the dotted lines indicate the positions 60b and 60b of the doors 60 and 60 when the doors are open. Here, when the second parking device 53b is to be entered, the doors 60, 60 are opened to positions 60b, 60b. (However, in this case, the cage 55a is not located in the illustrated position.) Next, the first parking device 53
When entering a, move the doors 60, 60 to position 60.
The door is closed as shown in a and 60a. In this way, the driver of the car that has entered the cage 55a will judge that the door 60, 60 is blocking the forward path and will stop without making a mistake, and the driver of the car will enter the cage 55a.
Stop at 5a.

However, in such a parking device 51, the manager who manages the operation of the parking device 51 is located near the operation panel 61 fixedly installed near the entrance/exit 58, for example near the manager's position 62, and controls the inside of the shaft 52. It is normal to carry out safety monitoring and confirm that no one is present before driving.
Even in case b, if the person does not leave and remains behind the door 60 or 60, the person cannot be seen at all, and if the vehicle continues to operate,
Extremely dangerous.

In response to these contradictory demands, it is possible to use a transparent material for a part of the door, or to make it mesh so that the interior can be seen through, but it would be easy to damage or it would affect the aesthetics. There were some inconveniences, such as unfavorable points.

The present invention was made to improve this situation, and it provides a safe tandem system that not only gives correct instructions to the users of the parking system, but also makes it easy to monitor unattended inside the parking shaft. This invention was made to provide a guide device for a parking device.

(b) Structure of the invention [Means for solving the problem] In accordance with this purpose, the present invention provides a parallel parking system in which a plurality of mechanical parking systems are arranged in parallel in the front and back direction.
