Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional parking apparatus in which a plurality of cages for mounting automobiles are vertically three-dimensionally circulated so that a plurality of vehicles can be parked in a narrow area.

[0002]

2. Description of the Related Art As a circulating type three-dimensional parking device, various structures have been proposed. For example, JP-A-2-14777
In No. 4, a pair of rail bodies that form an annular movement path along a vertical surface are provided to face each other, and a chain that movably fits to each of the rail bodies is provided. The cage mounting members are placed at the same horizontal position opposite to each other, both ends of the car cage are suspended and supported by the cage mounting members located at the same horizontal position, and the sprockets meshed with both chains are driven in a predetermined manner. There is disclosed a circulation type multi-level parking device configured to be rotated together by means.

[0003]

However, in the circulation type three-dimensional parking apparatus disclosed in Japanese Patent Laid-Open No. 2-147774, the chain is fitted to the rail body and the sprocket arranged at one position of the rail body is used. Since the structure is such that the chain is pushed and moved, the frictional force between the chain and the rail body is strong, making it difficult to move the chain smoothly and the durability of the chain and rail body. I'm worried about.

Further, since the front and rear central portions of the car-mounted cage are coaxially suspended and supported, there is a problem that the car-mounted cage fluctuates. For this reason, a roller is separately attached to a portion of the car cage away from the hanging portion, and a guide rail through which the roller passes is arranged to prevent the car cage from shaking, but the structure becomes complicated. In addition, there is a problem in that it is not possible to prevent backlash due to a gap between the roller and the guide rail.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a multi-level parking apparatus which is excellent in safety and durability and which can prevent the on-vehicle cage from swinging with a simple structure.

[0006]

In order to achieve the above object, the multi-story parking apparatus of the present invention comprises a link chain in which a number of links corresponding to the number of vehicles to be mounted are connected in an annular shape, and a link chain of the link chain. Two parallel guide rails, which are vertically arranged at predetermined intervals and guide the connecting shafts, and at least two connecting shafts of the connecting shafts passing through the two guide rails are always meshed with each other, and a driving device is provided. 2 sets of Geneva gears that rotate by a predetermined distance are provided at the front and rear, and a car cage is suspended and supported at two predetermined positions of the link corresponding to the front and back of the link chain. The front and rear suspension positions are eccentric in opposite directions at equal intervals from the center of the vehicle-mounted cage, and are suspended and supported at two points separated by a predetermined distance when viewed from the front. And wherein the are.

[0007]

The circulation type multi-level parking apparatus of the present invention has a structure in which a Geneva gear is used to pull up and rotate a link chain formed by connecting a number of links corresponding to the number of vehicles to be mounted in an annular shape. Since the number of links is small and the number of linking portions is small, it is possible to manufacture the chain with higher rigidity and strength than a normal chain, and it is possible to dramatically improve safety and durability.

Further, since the cage is mounted in front of and behind the car cage, it is hung and supported at positions eccentric in opposite directions at equal intervals from the center of the cage, that is, at two points separated by a predetermined distance when viewed from the front. The cage can be prevented from shaking.

It is considered that a twisting force acts on the on-vehicle cage by suspending and supporting positions on the front and rear of the on-vehicle cage that are eccentric in opposite directions and are not on the same axis, but this twisting force is It can be regulated by a guide rail that holds the link connecting shaft.

A Geneva gear 26 and a sprocket 27 are rotatably supported by a rotary shaft 25 on the upper portions of the frames 23 and 24, though not shown in the drawings. Although not shown, the rotary shaft 25, the Geneva gear 26, and the sprocket 27 are provided in two sets at the front and rear at predetermined intervals. In this case, in this embodiment, the axial centers of the front and rear rotary shafts 25 are arranged in parallel with each other with a predetermined gap, for the reason described later.

A motor 29 is installed on each of the frames 23 and 24, and a drive chain 31 is stretched between a drive sprocket 30 and the sprocket 27 which are interlocked with the motor 29. Since the sprocket 27 is a large-sized one, it is constructed by attaching teeth 27a that mesh with the chain 31 at four locations on the outer periphery of a disk-shaped member. Further, the Geneva gear 26 has four teeth 26a protruding at 90 degree intervals, and a connecting shaft 33 of a link chain 32 described later is introduced into the groove 26b thereof.

Referring also to FIG. 2, the link chain 32 is constituted by connecting a number of cars, in this embodiment, seven links 34, which corresponds to the number of automobiles mounted, endlessly by a connecting shaft 33. Each of the links 34 has a shape in which one end thereof is bent outward in an L-shape, and a vehicle-mounted cage 35 is suspended and supported via a support shaft 36 at the ends of the bent portions 34a. Has been done. In the case of this embodiment, the bent portion 34a of the link 34 is bent by approximately 90 degrees with respect to the main body portion, but this angle is set to the support shaft 36 of the adjacent vehicle cage 35 at the time of corner cutting described later. 36
It is preferable to set the positions so that they are farthest apart.

As shown in FIGS.
Is a bottom plate 37 on which an automobile rides, and hanging hands 38a and 38b connected to the front and back of the bottom plate 37, and hanging hands 38a and 38.
Two support shafts 36a, 3 which are installed in parallel in the upper center of b
6b and. In this case, one support shaft 36a
One end of, for example, protrudes from the front-side hanging hand 38a, and is pivotally supported at the tip of the bent portion 34a of the predetermined link 34 arranged on the front side. Further, one end of the other support shaft 36b is
It protrudes from the rear side hanger 38b and is pivotally supported by a bent portion 34a of a predetermined link 34 arranged on the rear side.

The link 34 is formed by arranging two plates having an H-shaped cross section in parallel in order to improve the strength, and the Geneva gear 26 described above is provided at the intermediate portion of the connecting shaft 33 penetrating them. The teeth 26a of the above are fitted.

Both ends of the connecting shaft 33 project to the front and back of the two plates constituting the link 34, and rollers (not shown) are attached thereto. Referring also to FIG. 1, when the link chain 32 rotates to move the links 34 on both sides of the track thereof, the guide rails 39 for guiding the both ends of the connecting shaft 33 are sandwiched between the front and rear surfaces. Are arranged above and below.

As described above, two sets of the rotating mechanism constituted by the Geneva gear 26, the link chain 32, the guide rail 39, etc. are provided in front of and behind the circulation type multi-level parking apparatus 21, and the vehicle-mounted cage 35, Support shaft 36 in two places before and after that
It is suspended and supported via a and 36b. In this case, as shown in FIG. 4, the support shaft 36a supporting the front surface side
Is eccentric by a predetermined distance a from the center of the on-vehicle cage 35, and the support shaft 36b supporting the rear surface side is eccentric by a predetermined distance b from the center of the on-vehicle cage 35.

The distances a and b are equal to each other, and as a result, the vehicle-mounted cage 35 has its hanging hand 38.
two support shafts 36a that are equidistant from the centers of a and 38b,
It will be supported by 36b, and thereby it is possible to prevent the on-vehicle cage 35 from rocking to the left and right. In this case, the support shaft 36a protruding to the front side is
A spindle 3 that is eccentric to the left of the center and projects to the rear side
Since 6b is eccentric to the right side from the center, it is considered that a twisting force acts on the vehicle-mounted cage 35, but this twisting force is restricted by the guide rail 39 that holds the connecting shaft 33 of the link 34.

In the above-described structure, the vehicle 4 is mounted on the bottommost car cage 35 located on the ground 22 in FIG.
0 unloading is done. When the automobile 40 is mounted on the vehicle-mounted cage 35 at the lowermost stage, the motor 29 operates and the Geneva gear 26 rotates via the drive sprocket 30, the drive chain 31, and the sprocket 27. The Geneva gear 26 is the connecting shaft 3 of the link chain 32.

As a result, in the case of this embodiment, seven vehicle-mounted cages 35 circulate together with the link chains 32, which are suspended and supported by the bent portions 34a of the links 34 constituting the link chains 32 via the support shafts 36. Then, when the vehicle-mounted cage in which the vehicle to be taken out or the empty vehicle-mounted cage for mounting a new vehicle reach the bottom, the motor 29 stops and the vehicle-mounted cage 35.
Will stop moving and cars will be taken in and out.

In this case, when the on-vehicle cage 35 orbits the upper and lower ends of the orbit of the link chain 32, an interference phenomenon, in which adjacent on-vehicle cages 35 approach each other and enter the mutual area, that is, a corner cut occurs. . However, in the parking device 21 of this embodiment, as shown in FIG. 2, the distance A between the support shafts 36 when the adjacent vehicle-mounted cages 35 approach each other.
However, in other states, for example, it spreads far more than when moving on both sides of the link chain 32. As a result, the corner cut can be made smaller than in the case where the bending portion 34a is not provided in the link 34 and the in-vehicle cage 35 is suspended on the connecting shaft 33. As a result, even if the length of the link 34 is short, the corner cut can be made small, and as many car cages 35 as possible can be suspended and supported in the three-dimensional parking apparatus 21 having a limited width and height. .

Further, as described above, the car cage 35
Is supported by two support shafts 36a, 36b that are separated from each other by the same distance in the opposite direction from the centers of the hanging hands 38a, 38b, and is supported at two points separated by a predetermined distance when viewed from the front. It is possible to prevent the on-vehicle cage 35 from swinging left and right.

A link chain 43 in which (the link 42 does not have a bent portion at one end) is annularly connected by a connecting shaft 33.
Is used. Then, in order to rotate the link chain 43, the same Geneva gear 26 as in the above embodiment,
Sprocket 27, motor 29, drive sprocket 3
0, a drive chain 31 is provided. Further, two parallel guide rails 39 for guiding the connecting shaft 33 are arranged on both sides of the track of the link chain 43.

Two sets of rotating devices for these link chains 43 are arranged on the front and rear surfaces of the multi-level parking device 41 so as to face each other, and the on-vehicle cage 35 has two connecting shafts for connecting the front and rear link chains 43. It is suspended and supported at positions 33 and 33 '. Also in the case of this embodiment, the support position on the front surface side of the vehicle-mounted cage 35 is set to the vehicle-mounted cage 3
It is eccentric to the left from the center of the vehicle 5 by a predetermined distance, and the support position on the rear surface side is eccentric to the right from the center of the vehicle-mounted cage 35 by the same distance as described above.

That is, the rotating devices arranged on the front and rear surfaces of the multi-level parking device 41 are arranged so that the positions of the connecting shafts 33 and 33 'are displaced as described above, and the on-vehicle cage 35 is arranged from the front. As seen, they are suspended and supported at the above-mentioned two points with a predetermined interval. As a result, the vehicle-mounted cage 35 is prevented from swinging also in the multilevel parking apparatus 41 of this embodiment.
