Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation type multi-level parking apparatus intended to circulate a plurality of vehicle mounts in a loop shape in the vertical direction to improve parking efficiency.

[0002]

2. Description of the Related Art A so-called vertical circulation type multi-story parking system is known as a parking system intended to improve parking efficiency.

The basic structure of the parking device will be described below. (This type of parking device includes a ground type in which the vehicle mounting body circulates in a parking ridge built on the ground, and an underground type. There is an underground type where the vehicle mounting body circulates in the parking ridge built in, but the underground type will be explained as an example).

First, a pair of upper sprockets parallel to each other are arranged in an upper portion inside a parking ridge constructed underground, and a positional relationship similar to that of the upper sprocket is provided in an inner lower portion of the parking ridge. And a pair of lower sprockets facing each other in parallel.

Two chains are wound around the upper sprocket and the lower sprocket in parallel, and the chains are rotated in a fixed direction by rotationally driving the upper sprocket.

Between the parallel chains, a proper number of vehicle mounts are mounted at an appropriate pitch so as to rotate integrally with the chains while always maintaining a horizontal state. Then, the pallet upper surface at the highest position is configured to be substantially flush with the ground surface, and after the vehicle is loaded onto the pallet at the highest position, the upper sprocket is rotated to move vertically in the ground. It is configured to accommodate a large number of vehicles.

By the way, in the parking device having the above structure, the specific structure for the vehicle mounting body to rotate integrally with the chain while always maintaining the horizontal state is as follows.

That is, FIG. 6 (the upper sprocket 5
0 (the pallet 51 is used as the vehicle mount) or FIG. 7 (the vicinity of the upper sprocket 50 is shown, and the suspension frame 53 having the pallet 52 at the bottom is used as the vehicle mount). As shown in FIG. 5, a mountain-shaped vehicle mount support 55 is attached to the two chains 54, 54 so as to face each other so as to stand upright in the radial direction of the sprocket 50. In FIG. 6, support shafts 56, 56 horizontally projecting from the central portion of the front and rear end surfaces of the pallet horizontally on the same line in the front-rear direction are rotatably attached to the front end portion of the vehicle supporter 55. In FIG. 7, support shafts 56, 56 projecting from the upper part of the suspension frame 53 in the same line in the front-rear direction are rotatably attached.

In this state, the vehicle mount 51 (5
3) freely tilts or swings left and right around the support shafts 56, 56. Therefore, the vehicle mount 51 (5
3) Guide rollers 5 are provided on the left and right end portions of the front and rear end faces, respectively.
8a and 58b are provided so as to project, and the guide rollers 58a and 58 are provided.
b is guided by the guide rails 57a and 57b arranged so as to face the left and right sides of the chain 54,
The vehicle mount 51 (53) is prevented from tilting to the left or right or swinging to the left or right to maintain the horizontal state.

[0010]

However, in the above-mentioned conventional structure, the vehicle mounting body 51 (53) is essentially left-right centered on the support shafts 56, 56 projecting on the same line in the front-rear direction. The guide rollers 58a and 58b are forcibly restricted by the guide rollers 58a and 58b being guided by the guide rails 57a and 57b. 5
There is a problem that the friction between the guide rails 57a and 57b and the guide rails 57a and 57b is extremely large, which causes large noise and vibration.

In particular, in FIGS. 6 and 7, when the left guide roller 58a is separated from the left guide rail 57a and the right guide roller 58b starts to protrude into the right guide rail 57b, the separation is caused by the separation. The generated noise and the collision noise and vibration generated by the plunge are extremely large, which has been a serious problem that the existence of this type of parking device is not allowed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vertical circulation type multi-level parking apparatus capable of keeping the vehicle mounting body horizontal while suppressing the generation of the noise as much as possible. There is.

[0013]

In order to solve the above-mentioned problems, the present invention has two endless chains arranged in parallel in the longitudinal direction and rotating simultaneously in the same direction, and a support shaft extending in opposite directions. Each of the support shafts is provided with an appropriate number of vehicle mounts that are integrally movable with the endless chain and rotatably attached, and the support shafts of the vehicle mounts are arranged with their positions vertically displaced. It has a configured structure.

[0014]

The vehicle mounting body circulates with the rotation of the endless chain. At this time, since the support shaft of the vehicle mount is rotatably attached to the endless chain, the support shaft tries to rotate about each support shaft.
Here, since each of the support shafts is provided so as to be displaced in the vertical direction, the vehicle mounting body has two rotation shafts. Therefore, the rotations about the respective rotation axes are mutually regulated, and the vehicle mount is kept horizontal.

In order to further ensure the horizontal maintenance of the vehicle mounting body, a guide rail for assisting horizontal maintenance is provided, and the vehicle mounting body is provided with a guide roller engaging with the guide rail. However, even in this case, the vehicle mounting body originally has a horizontal maintaining function because the support shafts thereof are arranged so as to be vertically displaced, and the guide rail and the guide roller simply have the same function. Since it only assists the leveling function, the friction between the guide rail and the guide roller is not so large, and the noise is less generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall schematic perspective view showing an embodiment of the device of the present invention, showing a parking device provided in a parking ridge 1 constructed underground. In the figure, A is the doorway of the vehicle to this parking device.

A pair of parallel upper sprockets 2a and 2b are arranged in the upper part of the parking ridge 1 so as to be vertically offset from each other. A pair of lower sprockets 3a and 3b are arranged in the same positional relationship. In the embodiment shown in the drawings, the sprockets 2a, 3a on the vehicle entrance / exit A side are positioned high. The upper and lower sprockets 2
a, 3a, 2b, 3b have two endless chains 4a,
4b are wound in parallel, and the pair of upper sprockets 2a, 2b are simultaneously rotated by the motor 5 in the same direction, whereby the two endless chains 4a, 4b are simultaneously rotated in the same direction. In the figure, 6 is a chain guide that prevents the chains 4a and 4b from swinging.

Between the two endless chains 4a and 4b, a rectangular pallet 8 as a vehicle mount 7 is supported in a proper pitch at an appropriate pitch so that its longitudinal direction is sandwiched between the chains 4a and 4b. The chains 4a and 4b are integrally moved while always maintaining a horizontal state.

Explaining this point in detail, first, a front support shaft 9 is firmly provided at the center of the end face of the pallet 8 on the vehicle entrance / exit A side. The front support shaft 9 is rotatable at the tip of a mountain-shaped vehicle mount support (pallet support) 10a attached to the chain 4a on the vehicle entrance / exit A side so as to stand in the radial direction of the sprocket. Be attached to.

On the other hand, at the center of the rear end surface 8a of the pallet 8, an upright member 11 having an isosceles triangular shape is attached by firmly fixing its bottom side to the rear end surface 8a of the pallet 8. The standing member 11 may be molded integrally with the pallet 8. A rear support shaft 12 is firmly provided on the top side of the standing member 11 toward the rear of the apparatus. Then, the rear support shaft 12 is arranged so that the chain 4 on the inner side of the device is raised so as to stand in the radial direction of the sprocket.
It is rotatably attached to the tip of a mountain-shaped vehicle supporter (pallet supporter) 10b attached to b.

That is, the front support shaft 9 and the rear support shaft 12 are located on the same line in a plan view and vertically offset in a side view.

As a result, the pallet 8 tends to rotate about the front support shaft 9 in the front portion (vehicle entrance / exit side), but the bottom side of the standing member 11 is fixed to the pallet rear portion. Since there is no rotation axis on the same line as the front support shaft 9, the rotation is suppressed.
Further, the pallet 8 tends to rotate about the rear support shaft 12 at the rear part thereof, but since there is no rotary shaft on the same line as the rear support shaft 12 at the front part of the pallet, the Rotation is suppressed. That is, the front support shaft 9 and the rear support shaft 12 that support the pallet 8
Since and are vertically displaced, the respective support shafts 9,
Rotation around 12 is mutually regulated and the pallet 8 is
Will always remain horizontal.

In the illustrated embodiment, a guide roller having a rotation axis parallel to the rear support shaft 12 is provided at the center of the bottom side of the upright member 11 in order to further ensure the horizontal maintenance of the pallet 8. 13 is provided in a protruding manner, and the guide roller is guided by a guide rail 14 arranged in a loop.

The guide rail 14 is used for the pallet 8
It is located inside (front side) of the apparatus back side chain 4b along the locus drawn by the guide roller 13 due to the circulation of. The guide rail 14 is composed of an outer rail 14a and an inner rail 14b, which are opposed to each other with the guide roller 13 interposed therebetween.
b is fixed to the back wall 1b of the parking ridge 1.

The rear support shaft 12 has a radius of the sprocket 2b, 3b and a radius of the pallet support 10 above and below the sprocket 2b, 3b on the rear side of the apparatus.
It passes on a semicircle whose radius is the sum of the heights of b, and in the straight part of the guide rail 14, is linearly sandwiched between the outer rail 14a and the inner rail 14b (see FIG. 4). ). Therefore, notches 15 and 16 for allowing the rear support shaft 12 to pass therethrough are provided on the left and right portions of the inner rail 14b of the device rear side upper sprocket 2b, and the device rear side lower sprocket of the outer rail 14a is provided. 3b
Cutouts 17 and 18 for allowing the rear support shaft 12 to pass through are provided in the left and right portions of the.

Then, the notches 15, 16, 17, 1
As shown in FIG. 4, auxiliary rails 19, 20, 21, 2 which can be freely opened and closed in the direction in which the rear support shaft 12 passes are shown in FIG.
2 is hinged and each of the notches 15, 16, 17, 1
8, the guide roller 13 is prevented from coming off the guide rail 14. The auxiliary rails 19, 2
0, 21, 22 are urged in a closing direction by springs or the like, and the rear support shaft 12 has the auxiliary rails 19, 20,
21 and 22 are pushed open and passed.

As described above, by guiding the guide roller 13 to the guide rail 14, the stability of the rear side of the pallet 8 is maintained, and the horizontal maintenance of the pallet 8 is further ensured.

The pallet 8 is constructed so that the front and rear support shafts 9 and 12 are vertically displaced so that the pallet 8 is originally kept horizontal.
Since 4 only assists the horizontal maintenance of the pallet 8, the friction between the guide rail 14 and the guide roller 13 is not so large, and the generation of noise is small. Further, if the guide roller 13 is composed of a pneumatic tire, the generation of noise is almost eliminated.

FIG. 5 shows that the vehicle mount 7 has a suspension frame 22.
2 shows a specific example of the present invention in the case where the pallet 23 is arranged on the bottom of the hanging frame.

In this case, the front support shaft 9 projects from the upper frame on the front side of the suspension frame 22, and the rear support shaft 12 is firmly attached to the upper frame 22a on the rear side of the suspension frame 7. The front and rear support shafts 9 and 12, which are firmly projected from the tip of the fixed isosceles triangular upright member 11,
Each of them is rotatably attached to a vehicle mount support tool (hanging frame support tool) 10b attached to the chain 4b.

As a result, the front support shaft 9 and the rear support shaft 12 are vertically displaced so that the suspension frame 22 is prevented from swinging. Incidentally, as in the above embodiment,
The standing member 11 is provided with a guide roller 13 in order to ensure the horizontal maintenance of the hanging frame 22.
The guide roller 13 is guided by the guide rail 14.

[0033]

According to the present invention, since the support shafts of the vehicle mounting body are vertically displaced, the vehicle mounting body is supported between the chains so that the vehicle mounting body is originally kept horizontal. Therefore, there is an effect that the problem of noise generation does not occur because the forcible horizontal maintaining means as in the related art is unnecessary.
