Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a circulating type parking system in which a plurality of cages carrying automobiles are held in a three-dimensional space and a large number of automobiles are parked within a narrow flat area. This invention relates to a multilevel parking device.

[Conventional technology] Currently, in areas with extremely high density of buildings such as urban areas, there is a significant shortage of available parking area for the number of vehicles that can be accommodated. These facilities are becoming indispensable in today's urban areas. Among these, the so-called circulating multi-level parking system, in which a car cage is circulated upward from the ground in a circular manner to store and remove cars, is relatively simple in structure and equipment compared to other multi-level parking systems. , is widely used.

As a conventional multilevel parking system of this kind, one is known in which the upper end of the cage is pivotally attached to a circular rotor, and the rotor is rotated to circulate the vehicle.

[Problems to be Solved by the Invention] However, in the case of rotating the rotor to circulate the cage as described above, there is a drawback that the number of cars that can be accommodated is small in relation to the area occupied by the site. In other words, in order to increase the number of cages that can be accommodated relative to the area occupied by the site, it is necessary to transport the cages higher.
In the conventional device described above, in order to transport the cage upward, it is necessary to increase the diameter of the rotor, and if the diameter is increased, the area occupied by the site will inevitably increase, and the ratio of the number of cars accommodated to the site area will increase. could not be increased.

There is also a system that circulates the cage by pulling both ends of the horizontal rotating shaft of the cage along a guide member with a chain, but the conventional device is complicated and there is a risk that the chain may break due to the weight of the vehicle.

This invention was made with attention to the above-mentioned problems, and is a recirculating multi-level parking system that can increase the number of cars accommodated regardless of the site area, and that can ensure sufficient safety with an inexpensive and simple configuration. For the purpose of providing.

[Means for Solving the Problems] The present invention provides a pair of rail bodies that form an annular movement path along a vertical plane, each of which has a chain movably fitted therein, and a plurality of cages protruding from both chains. The sprocket is rotatably attached to the mounting member at the upper end of both sides of the automobile loading cage, and the sprockets meshed with both chains are rotated together by a predetermined driving means.

[Function] In the circulating multilevel parking system having the above configuration, the car loading cage is conveyed and held by the chain, so the car storage is controlled by the length of the vertical diameter of the annular movement path formed by the rail body. You can decide on the number of machines. Therefore, an apparatus having a desired number of cages can be installed as long as the site area is as small as possible so that the two circulating cages do not interfere with each other.

In addition, in this invention, since the entire side circumference of the chain is supported by the rail, the gravity of the cage and the car is supported by the chain between the cage mounting member and the sprocket, and the entire weight is supported by the chain's tensile force. No need for support.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

In the figure, l and 1' are a pair of oval-shaped rail bodies, and vertically erected supports 2a, 2b and 2a',
2b' are supported so as to face each other in the front and rear (right and left in FIG. 2) at a predetermined interval (an interval slightly longer than the front-to-back length of the vehicle to be loaded). Further, each of the rail bodies 1.1' has a substantially U-shaped cross section, as shown in FIGS. 3 and 4.

3.3° is a roller chain inserted into the rail body 1.1', and the rollers 3a, 3a' are connected to the rail body 1.1'. l
' and smoothly press it against the inner wall of the rail body 1. It is designed to be able to move within l°. Reference numeral 4.4' denotes a plurality of cage attachment members (six in the figure) attached at equal intervals at 3.3 degrees of the roller chain. Each cage mounting member 4
．． 4' are two parts of the same length whose one ends are connected to each other.
The other ends of both plates 4a, 4b and 4a', 4b' are connected to one side of the roller chain 3, 3°.
It is coaxially mounted with “a”.

The connecting portions 41 and 41' of both plates are connected to the rail body 1.
1" and protrudes outward from the annular travel path formed by the 1".

Reference numeral 5 designates a plurality of cages (six in the figure) for loading automobiles, and the upper ends of each cage 5 on both sides thereof are rotatably attached to the cage attachment members 4, 4° connecting portions 41 and 41'. Therefore, the bottom surface portion 5a is always held horizontally regardless of the position.

6.6' is a sprocket meshed with each of the roller chains 3, 3', and each of them is connected to a motor 7 as a driving means.
It is fixed to a drive shaft 8 which rotates by. The driving force of the motor 7 is the gear 9, the chain lO, and the gear 11.
is transmitted to the drive shaft 7 via.

Based on the above configuration, the operation will be explained next.

The motor 7 is driven, and the sprocket 6.
When rotated through 6 degrees, the roller chains 3 and 3' meshing with each sprocket 6 and 6 degrees move respectively to the rail bodies 1 and 3'. The cage 5 also moves along the annular path together with the roller chains 3 and 3' while maintaining the horizontal state of the bottom surface 5a.

When parking the car, move the empty cage 5 to the lowest position, drive the car into the cage as shown in FIG. let it hold.

Note that when a car loaded in a cage is held in the air, a considerable amount of gravity is applied, so roller chains 3.3
However, in this embodiment, the rollers 3al and 3a2 mounted coaxially with the mounting member 4.4' are
and 3a1'3a2° are the rail body 1 as shown in FIG.
．． Roller chain 3 is in contact with both left and right walls of 1'
．． At 3°, there are horizontal forces Fl, F3 and vertical forces F
2. F4 will be added. Of these, Fl, F3
is canceled by the reaction force of the side wall of the rail body, and the vertical force F
2. F4 acts on the chain in opposite directions, so they cancel each other out.

Moreover, since the chains 4, 4' are supported and regulated around the entire circumference, they are almost in the same state as a rigid body, and therefore the gravity of the cage and the car is applied to the cage mounting members and sprockets. Since the entire weight does not act as a tensile force on the chain, there is no risk of the chain breaking.

Further, in the above device, by changing the length of the major axis of the movement path formed by the rail bodies 1, 1°, the number of cages to be attached, that is, the number of cars that can be accommodated can be changed. Therefore, any number of cages can be accommodated as long as the site area is large enough to prevent two cages 5 from interfering with each other during movement.

In the above embodiment, a roller chain was used to smoothly convey the cage, but a chain without rollers may also be used.

[Effects of the Invention] As explained above, according to the circulating multi-level parking device according to the present invention, the required number of parking spaces can be obtained without increasing the site area, and there is no risk of the chain breaking. Sufficient safety can be ensured.

Furthermore, since the configuration is simple, there is also the effect that equipment costs can be significantly reduced.
