Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a parking device for loading a vehicle onto a pallet and parking the vehicle at a predetermined position, and particularly relates to a device for preventing a vehicle door from opening due to movement vibration of the pallet. .

<Prior art> In general, there are various types of parking devices, including a vertical circulation system (so-called merry-go-round system), a horizontal circulation system, and a two-stage (multi-stage) elevating and traversing system. It is loaded, moved to a designated storage position by remote control, and parked.
Also, a predetermined pallet is moved to a predetermined delivery position and delivered. However, when the driver drove the vehicle onto the pallet and parked it, he did not notice that the door was ajar, and when he operated the operation panel to move the pallet loaded with the vehicle, vibrations caused by the movement of the pallet at that time, or several times after that, occurred. The vibrations caused by the movement of the pallets accumulate, causing the vehicle door to open suddenly.
There is a problem in that they can hit other cars or come into contact with machinery, leading to unexpected accidents. Therefore, conventionally,
As shown in Japanese Patent Publication No. 49-14588, a device for preventing accidents caused by half-opening of a car door in a cage for accommodating a car has been proposed. In this system, bars (or ropes) that can be placed near the car door are installed on both sides of the cage that houses the car, and when the car is put into the cage, the bars (or ropes) are manually pulled. Pull it up and position it near the car door to prevent the car door from opening and prevent accidents, and when taking the car out of the cage.
The bar (or rope) is manually lowered and released to allow boarding and alighting.

<Problems to be solved by the invention> However, with the conventional device, it is necessary to manually set the car door half-open accident prevention device, so after the car is parked in the cage,
The work of manually setting the bars (or ropes) on both sides of the vehicle was a very tedious work, considering the number of times it was done each day, and there was a risk that it would be easy to forget.

<Means for Solving the Problems> The present invention was developed in view of the above-mentioned problems, and the technical problem is to automatically implement a device to prevent accidents caused by vehicle doors being left ajar. The means to achieve the technical problem is to provide a support at the rear of each pallet on which a vehicle is loaded, provide a driving wheel and a driven wheel at the top and bottom of this support, and wind a connecting member between both wheels. preventive fittings rotatably attached to the front side of the pallet are arranged on both sides of the pallet, and each of the preventing fittings is attached to the connecting member via a connecting rod,
A motor is connected to the drive wheel, and when the motor is driven, the prevention fitting is lifted up via the connection member and positioned near the vehicle door, so that opening of the vehicle door is prevented or detected.

<Operation> According to this technical means, when moving a pallet loaded with a vehicle, the motor is driven to rotate the drive wheel to move the connecting member, and lift the prevention fittings on both sides of the vehicle through the connecting rod. The pallet is then moved to a predetermined position. If a vehicle loaded on this pallet moves the pallet with its doors ajar, the vehicle door may open due to the vibration of the pallet movement.
The vehicle door may suddenly open due to the accumulation of vibrations from the movement of the pallet, but the above-mentioned prevention fitting prevents the vehicle door from opening wide and prevents contact accidents, and detects the opening of the vehicle door and prevents the pallet from opening. Accidents can be prevented by stopping movement or issuing a warning.

<Example> The present invention will be described below based on an example shown in the drawings. Figures 1 and 2 show an example in which the door opening safety device of the present invention is installed on a pallet of a two-tiered parking system. A driving wheel 5 is provided in the lower part, and a driven wheel 6 is provided in the upper part.
A connecting member 7 such as a chain connects between the two. The drive wheel 5 is connected to the drive shaft of a motor 10 which is a drive source provided at the rear of the pallet 2, and when the motor 10 is driven, the drive wheel 5 rotates, and the driven wheel 6 also rotates via the connecting member 7. It's becoming like that. Further, on both sides of the front part of the pallet 2, prevention fittings 3 and 3' are rotatably supported by pins 4, and at the other ends of these prevention fittings 3 and 3', part A in Fig. 1 is attached. As shown in the enlarged view of FIG. 3, a groove 13 is provided, and a connecting rod 8 is inserted into this groove 13 to connect the two prevention fittings 3, 3'. Connecting rod 8
is fixed to the connecting member 7, and moves up and down while moving inside the groove 13 as the connecting member 7 moves up and down. That is, as the connecting member 7 moves up and down, the connecting rod 8 moves within the groove 13, and the preventing fittings 3, 3'
is designed to rotate vertically around pin 4. A groove 13 is provided in each of the preventive fittings 3, 3'. This may be done by making it possible to slide and roll within this groove 13. in this case,
The other ends of the prevention fittings 3, 3' are rotatably attached to the connecting member 7. Further, the motor 10 is a motor with a brake that can stop and hold the drive wheel 5, and the connecting rod 8 fixed to the connecting member 7 moves to the right end in the groove 13 provided in the prevention fittings 3, 3'. At this position, the rotation is stopped and the prevention fittings 3, 3' are held near both sides of the vehicle 1.
Reference numeral 11 denotes a traverse wheel that slides the pallet 2 in the traverse direction. Reference numeral 12 denotes a pawl that prevents the vehicle 1 from moving in the front-back direction, and when the rear wheels of the vehicle 1 run over and fit between the pawls 12, parking can be completed.

The operation of one embodiment of the present invention having such a configuration will be explained.

First, normally, the connecting rod 8 is moved by the driving of the motor 10 via the driving wheel 5, the driven wheel 6, and the connecting member 7, and the prevention fittings 3, 3' rotate around the pin 4 and are attached to both sides of the pallet 2. In this state, the vehicle 1 is not parked on the pallet 2.
In this state, if you want to put the vehicle 1 into a predetermined position, move the vehicle 1 backwards and drive onto the pallet 2, so that the rear wheels of the vehicle 1 hit the pawl 1 at the rear of the pallet 2.
Move it to a position where it fits between 2 and complete parking. After that, an operator such as a driver operates a push button switch (not shown) on a predetermined operation panel to send an activation signal to the motor 10, and based on this signal, the motor 10 is driven and the drive wheel 5 rotates, and this rotation also rotates the driven wheel 6 via the connecting member 7. Therefore, the connecting rod 8 fixed to the connecting member 7 moves upward and moves to the right in the figure in the groove 13 provided in the preventing fittings 3, 3', while moving both the preventing fittings 3, 3' to the right. As shown by the chain line in FIG. 1, the motor 10 is lifted up centering on the pin 4, and then the rotation of the motor 10 is stopped at a predetermined position, and the prevention fittings 3, 3' are held near both sides of the vehicle 1.
Further, the interlocking relay moves the pallet 2 in the traversing direction by the traversing wheels 11 or in the ascending and descending direction by the elevating drive device (not shown) to complete storage at a predetermined position. In this way, the vehicle 1 is driven by the motor 10 so that the prevention fittings 3 and 3' are
However, when vehicle 1 was parked on pallet 2, the driver did not notice that the door was ajar and operated the operation panel to move pallet 2. Even if the vehicle door suddenly opens due to vibrations or the like during the movement of the pallet 2, it will come into contact with the prevention fittings 3, 3' and will not open any further. In other words, the vehicle door is prevented from opening wide by the prevention fittings 3 and 3', so it does not protrude beyond the width of the pallet 2, does not hit other vehicles or come into contact with machinery, and remains in that state. Then, the pallet 2 continues to move, and the storage at the predetermined position can be completed. Next, if you want to take out the parked vehicle 1, you can return the pallet 2 by operating a return button switch (not shown) provided on the operation panel.
is moved in the transverse direction by the transverse wheels 11 or in the vertical direction by the vertical drive device (not shown) and returned to the original position. Thereafter, the motor 10 rotates in the opposite direction, causing the drive wheel 5 to rotate in the opposite direction, and this rotation causes the connecting rod 8 to move downward via the connecting member 7. Therefore, while the connecting rod 8 moves in the groove 13 to the left in the figure, the prevention fittings 3 and 3' move against the pin 4.
The vehicle 1 is rotated around the center and lowered to positions on both sides of the pallet 2, and both sides of the vehicle 1 are opened so that the driver can get on the vehicle, and the vehicle 1 can be taken out from above the pallet 2. Also, as mentioned above, the motor 1
0, the connecting rod 8 fixed to the connecting member 7 is moved upward to hold the preventing fittings 3, 3' near both sides of the vehicle 1, and the preventing fittings 3, 3' prevent the opening of the vehicle door. Although this has been prevented, when the vehicle door comes into contact with the prevention metal fittings 3, 3', this can be detected and the movement of the pallet 2 can be stopped or an alarm buzzer can be sounded to prevent the accident.

Although the embodiment described above has been described in which the door opening safety device of the present invention is installed in a two-level parking device, the present invention is not limited to this. It also works effectively in all parking devices.

<Effects> As is clear from the above, the present invention can automatically set the prevention fittings near the vehicle door through the connecting member and connecting rod by driving the motor, and can also set the prevention fittings on both sides of the vehicle through the connecting rod. Since it is attached to the connecting member, one motor can drive two prevention fittings, and there is an advantage that it is not necessary to provide one motor (driving means) for one prevention fitting.
