Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of the entrance/exit door of a multi-story parking lot.

(Prior art) Conventionally, in multi-story parking garages where vehicles are parked by raising and lowering them to the parking level below or to the parking level above, an entrance is provided in front of the lifting device, and two doors are moved up and down to create an entrance/exit. Either a 2UP door type was used to open and close the door, or a side-opening type door was used in which multiple doors were moved laterally to open and close.

(Problem to be solved by the invention) When a vehicle coming to park moves forward due to an incorrect driving operation while the lifting device is rising or falling, it will collide with the closed door, causing the door to close. If an accident occurs in which the vehicle comes off and falls downstairs, destroying the vehicle and injuring or killing the driver, and the elevator is lowering, the vehicle on the lowering elevator An accident had occurred in which the vehicle fell into the ground and destroyed both vehicles.

(Means for solving the problem) Main wire ropes are stretched in the moving direction on both sides of the door that opens and closes by moving the entrance, and a plurality of wire ropes are stretched between the two main wire ropes. Both ends were connected to the main wire rope in a sliding manner, and the plurality of wire ropes were attached to the back surface of the door so as to move together with the door.

(Function) A vehicle that is operated incorrectly will be captured by multiple wire ropes and the main rope and will not fall to the floor of the elevator, resulting in a major accident in which the vehicle will be severely damaged and the driver will be injured or killed. do not have.

(Example) An example shown in the drawings will be described below. Reference numeral 1 denotes an elevating device for a multi-story parking lot, which lifts and lowers vehicles that have entered the multi-story parking lot from an entrance 2 to take them into or out of the parking layer on the upper floor or the parking layer below. Reference numerals 3a and 3b are upper and lower doors of the entrance/exit 2, which are pulled upward by a mechanism not shown to open the entrance/exit 2.

4a and 4b are the main wire ropes stretched on both sides of the doors 3a and 3b, and the bolt fittings 4aD and 4bD at the lower ends.
is attached to the fixing fittings 5a and 5b fixed to the lower floor with anchor bolts and nuts, and the screw fitting 4 at the upper end
aU and 4bU are secured with nuts 7 to brackets 6a and 6b which are fixed to the upper wall surface with anchor bolts and nuts.

Reference numerals 8a, 8b, and 8c are wire ropes, and ring-shaped sliding fittings 9 connected to both ends of the wire ropes are slidably connected to the main wire ropes 4a, 4b. Wire ropes 8a, 8b, 8c are attached to door 3b
It is attached to the back surface of the body by an attachment fitting 10.

The Ministry of Construction assumes that a diving vehicle will generate a force of about 25 tons, so wire ropes 8a, 8b,
8c, main wire ropes 4a, 4b, fixing metal fittings 5
a, 5b, brackets 6a, 6b, etc. should be strong enough to withstand the force.

When opening the entrance/exit 2, the doors 3a, 3b are pulled upward by a mechanism not shown.
When the door 3b rises, the wire ropes 8a, 8b, 8
Since the wire c is attached to the back surface of the door 3b, it rises together with the door along the main wire ropes 4a and 4b, and opens the entrance/exit 2.

If the doors 3a, 3b are lowered and blocking the entrance/exit 2, and the vehicle c makes a mistake in driving and crashes into the doors 3a, 3b, even if the doors 3a, 3b come off the guides (not shown) or are damaged, the vehicle c will not be connected to the wire. It will not be caught by the ropes 8a, 8b, 8c or the main wire ropes 4a, 4b and fall downstairs. Therefore, vehicle c is not seriously damaged, the driver is not injured or killed, and vehicles located downstairs are not destroyed.

5 to 7 show a second embodiment, 51
a, 51b, 51c, 51d are doors; doors 51a,
51d runs on the rail 52a, and the door 51b,
51c runs on the rail 52b. 53a,
53b is an upper guide rail for doors 51a, 51b,
51c and 51d are guided so that they do not come off.

Brackets 54a and 54b are fixed to recesses in the floor on both sides of the doorway 2 with anchor bolts and nuts, and 55a and 55b are brackets fixed to the upper walls on both sides of the doorway 2 with anchor bolts and nuts.

56 is a lower main wire rope stretched in a long groove provided in the floor, and screw fittings 56 connected to both ends.
a, 56a are engaged with the brackets 54a, 54b by nuts 57.

Reference numeral 58 denotes an upper main wire rope, and screw fittings 58a, 58a connected to both ends thereof are connected to the bracket 55.
A and 55b are engaged with nuts 57 and an upper main wire rope 58 is stretched.

59a, 59b, 59c, and 59d are wire ropes, and ring-shaped sliding fittings 60 are connected to both ends of the wire ropes.
are slidingly connected to the main wire ropes 56, 58. Wire ropes 59a, 59
b is attached to the back side of the door 51b by an attachment fitting 61, and wire ropes 59c and 59d are attached to the back side of the door 51c.
It is fastened to the back surface of the board by a fastening metal fitting 61.

When opening the entrance/exit 2, a mechanism not shown moves the doors 51a, 51b to the right in FIG. 7 and the doors 51c, 51d to the left in FIG. Move to the right and wire ropes 59c and 59d will close to door 5.
Move to the left together with 1c and open the entrance/exit 2.

When the doors 51a, 51b, 51c, and 51d move to the center and block the entrance/exit 2 as shown in FIG.
Even if the doors 51b and 51c come off the rails 53 and guide rails 55 or are damaged when the vehicle c collides with the wire ropes 59a, 59b, 59c, 5
9d and the main wire ropes 56 and 58 and will not fall downstairs. Therefore, vehicle c is not seriously damaged, the driver is not injured or killed, and vehicles located downstairs are not destroyed.

(Effects of the invention) As described above, the present invention has main wire ropes stretched in the movement direction on both sides of the door that opens and closes by moving the entrance and exit, and a plurality of wire ropes between the two main wire ropes. Both ends of the wire ropes were connected to the main wire rope in a sliding manner, and the multiple wire ropes were attached to the back of the door so that they moved together with the door. Even if the cable becomes detached or damaged, the vehicle will be captured by the multiple wire ropes and the main rope and will not fall to the floor below the lifting device, preventing a major accident in which the vehicle will be damaged and the driver will be injured or killed. .
