It is.

[Prior art]

The present applicant previously disclosed in Japanese Patent Publication No. 56-25590 a ``vehicle door opening accident prevention device in a mobile parking facility''. As shown in FIGS. 6 and 7, this device is used in a vertical circulation parking system, which is a type of mobile parking equipment, and has a pivot point on the underfloor surface of the side of the chassis 100a of the vehicle mounting cage 100. A parallel link-shaped door opening prevention frame body 101 is provided so as to be swingable in one vertical plane, and the frame body 101 is attached to the vehicle chassis 10.
A driven member 102 and an arm 103 are fixed to the pivot point on the lower surface of Oa, and are normally maintained in an upright state by a spring 104 stretched between arm 103 and chassis 100a. Further, a frame drive mechanism 106 is installed on the fixed floor 105 at the vehicle entry position. This frame drive mechanism 106 has a fixed bed 105
A power cylinder 107 installed on the side, and a swing link 109 in the form of a horizontal parallel link installed along the fixed bed 105 surface via a buffer mechanism 108 at the tip of the plunger 107a of the power cylinder 107, the swing link Reference numeral 109 denotes a pushing member 10 which is designed to horizontally swing around an intermediate portion as a fulcrum, and one side of the tip of the swinging link 109 moves in the vehicle entry direction.
9a. When the vehicle W enters or exits the cage 100 stopped at the vehicle entry position, the plunger 107a of the power cylinder 107 extends to cause the pushing member 109a to collide with the driven member 102 via the swing link 109. ,
The door opening prevention frame body 101 is tilted against the spring 104 to allow the vehicle door to be completely opened and the driver to enter the vehicle W.

On the other hand, multiple vertical circulation parking devices mentioned above are arranged in tandem, and the last row of parking devices furthest from the vehicle entrance is equipped with all the cages that can be mounted at equal intervals, and the other parking devices are equipped with one cage.

In either case, the pushing plate 33a is moved by lowering the rack 29.
The outer periphery of the cover plate 28 contacts the outer edge of the small hole 28a to close the small hole 28a. and each cage 1
The door opening prevention frames 20 and 20' of numbers 0 and 16 are erected by the spring force of a tension spring 23.

From this point, the front row parking device 7 is displayed on the operation panel 38a.
When the car call button is pressed to enter or exit the parking lot a, the front row parking device 7a circulates the group of cages 10 and stops the desired cage 10 at the lowest entry position. This completes the chassis 11 of the desired cage 10.
The vehicle entry surface of is flush with the ground floor 12, and the driven member 26 of the door opening prevention frame 20 is connected to the frame drive mechanism 2.
It is located just above the push plate 33a of No.7.

Next, in the frame drive mechanism 27, the motor 34
is driven, and the rack 29, hollow cylinder 31, and pushing member 33 rise together, and during this rise, the pushing plate 33
a collides with the driven round bar 26b and the driven member 26

Next, the movable deck device 19
The deck 19a swings and tilts due to the extension of the rod _19b1 of the rod 9b, forming a ramp connecting the ground floor 12 and the fixed floor 13. Further, by the operation of the frame drive mechanism 27', the door opening prevention frame 20' of the desired cage 16 is tilted in the same manner as described above. Then the entrance door 5 opens,
When entering the warehouse, drive the vehicle W forward to the entrance/exit,
It enters the rear tower 3b through the deck 19a, fixed bed 13, and communication port 6, and gets into the cage 16. In the case of goods issue,
A driver similarly enters the rear tower 3b through the entrance/exit 4, gets into the vehicle W which is placed on the cage 16, ascends the communication opening 6, the fixed floor 13, and the deck 19a in reverse driving, and exits through the entrance/exit 4. In any case, in the frame drive mechanism 27, the pushing plate 33a closes the small hole 28a, so the vehicle W or person can move the fixed floor 1 without any hindrance.
You can pass over 3.

In addition, in the above-mentioned embodiment, the frame drive mechanism 27.
Although a rack and pinion is used as the vertical movement mechanism for the pushing member 33 of 27', an actuating cylinder such as an air cylinder, a hydraulic cylinder, or a power cylinder may also be used. Further, the frame drive mechanism 27' of the rear row parking device 7b may be replaced with the frame drive mechanism 106 shown as the prior art because vehicles and people do not pass over the fixed floor 18. Furthermore, although a tandem vertical circulation parking facility has been cited as an example of a mobile parking facility that employs the vehicle door opening accident prevention device of the present invention, it can also be applied to a tandem multi-stage parking facility that combines ascending/descending and traverse parking facilities.

[Effect of idea]

As detailed above, according to the vehicle door opening accident prevention device of the present invention, the frame drive mechanism is accommodated in a pit dug in a fixed floor at the vehicle entry position, the pit opening is covered with a cover plate, Only the pushing member of the frame drive mechanism can protrude upward from the small hole cut in the cover plate, and the pushing plate of the pushing member closes the small hole when not in use, so that the fixed floor cannot be used by vehicles or people. It has the great effect of expanding the scope of application of this type of device with a simple configuration, such as being able to be applied to mobile parking facilities that were previously difficult to apply, such as parallel vertical circulation type and multi-level parking facilities. It is something that plays.
