Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical three-dimensional parking system for passenger cars, and more specifically, a vertical circulation system in which vehicles are mounted in a plurality of cages and circulates in a ferris wheel type by a link chain. It relates to a parking device.

[0002]

2. Description of the Related Art In recent years, with the spread of automobiles and the shortage of parking lots due to the high price of land, the demand for multi-story parking systems has increased for the effective use of land, and the three-dimensional parking system is highly economical in terms of construction and maintenance. Parking equipment is desired. Generally, in a ferris wheel type vertical circulation type parking device using a link chain, as shown in FIG. 4, both the upper sprocket wheel 101 and the lower sprocket wheel 103 are rotatable, and the upper sprocket wheel 101 is connected to a motor 105 or the like. Cages 109, ..., 10 that are rotationally driven by a suitable drive mechanism via a drive chain 107 to mount and store the vehicle.
9, an arm 113 for supporting the link chain 111,
…, It is suspended by 113 and is circulated and driven vertically. As shown in FIG. 4, the upper sprocket wheel 101
Each of the lower sprocket wheel 103 and the lower sprocket wheel 103 is continuously provided with a sprocket groove 117 that meshes with the connecting pin 115 of the link chain 111 over the entire outer circumference. Naturally, the sprocket wheel used here has a very large diameter, which is very expensive to manufacture. Therefore, in consideration of economy, it is known that only the upper sprocket wheel 101 is used as a drive wheel with a sprocket groove, and the lower sprocket wheel 103 is not provided with a sprocket groove and a simple disk is a driven wheel.

[0003]

However, an endless link chain which is vertically circulated, a plurality of vehicle loading cages suspended and supported by arms thereof, and a plurality of vehicles mounted on the cages. All of the total load is being carried by the upper sprocket wheels, and the lower sprocket wheels are barely loaded. Therefore, if the lower sprocket wheel functions to move the link chain and the cage suspended and supported by the link chain along the predetermined path below the parking device, the lower sprocket wheel is connected to the link chain. It does not necessarily have to have a sprocket groove that engages with the pin, nor does it necessarily require rotation.

An object of the present invention is to simplify and construct a lower sprocket wheel in a vertical circulation type parking apparatus capable of accommodating a large number of vehicles in a three-dimensional manner without hindering entry and exit in a limited site, and in terms of construction and maintenance. An object is to provide a highly economical multi-story parking system.

[0005]

In order to achieve the above object, the multi-dimensional parking apparatus of the present invention has an endless link chain stretched between a pair of vertically spaced wheels. A plurality of cages for vehicle mounting are suspended and supported on a chain via an arm, an arm guide for regulating the trajectory of the cages is provided, and the upper wheel is rotated by an appropriate drive mechanism to vertically move the cage. In the three-dimensional parking device that is circulated in the direction, the upper wheel is a driving sprocket wheel and the lower wheel is a fixed guide rail that does not rotate, and is formed in an arc shape.

[0006]

[Function] The fixed guide rail is formed in an arc shape and provided in place of the lower wheel. When the link chain and the cage suspended and supported by the link chain are moved below the three-dimensional parking apparatus, a predetermined arc shape is formed. It functions as a guide to follow the locus of, and maintains a good relationship between the arm and the arm guide. Further, by providing the fixed guide rail in this way, the lower driven sprocket wheel and the bearing mechanism for supporting it can be omitted.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the whole of a multi-level parking apparatus according to the present invention, and a front portion of a frame of the entire apparatus is omitted for easy understanding. FIG. 2 is a sectional view taken along the line II-II in FIG.

In FIG. 1, 11 is one vehicle for each.
A cage for accommodating one by one, reference numerals 11a, 11b, ..., 1
Each is distinguished by 1 g. Cages 11a, 11b,
, 11g are suspended and supported by arms 13 ,. Arms 13, ..., 13
Are connected by connecting pins 15, ..., 15 to form a link plate of the endless link chain 17. Further, guide rollers 19, ..., 19 are provided on the arms 13 ,.
, 19 is guided by the guide rails 21 and 21, so that the link chain 17 in the vertically moving state is not bent.
The cage 11 is regulated to move along a vertical track.

Connecting pin 1 of endless link chain 17
, 15 move the endless link chain 17 as the upper sprocket wheel 23 rotates while engaging with the sprocket grooves 25, ..., 25 provided on the outer periphery of the upper sprocket wheel 23 at the upper side. The endless link chain 17 is guided downward along a substantially semi-circular fixed guide 27. By rotating the upper sprocket wheel 23, the cages 11a, 11a
b, ..., 11g circularly move vertically.

The endless link chain 17 is supported by the outer periphery of the upper sprocket wheel 23 in the upper part to hold the arcuate track of the cage 11, and in the lower part, the arcuate track of the cage 11 is secured by the fixed guide 27. To do.

The mounting mechanism of the fixed guide 27 will be described with reference to FIG. Numerals 29 and 29 are brackets fixed to the device frame 31, and bolts 33 and 33 are screwed and inserted. When the bolts 33, 33 are screw-turned so that the leg ends 35, 35 of the bolts 33, 33 press the tops of the blocks 37, 37 provided on the upper part of the fixed guide 27, the fixed guide 27 causes the fixed plates 39 ,. Move with
Tension is applied to the link chain 17. Therefore, the link chain 17 can be loosened by appropriately adjusting the bolts 33, 33. Fixed plate 39,
, 39 is moved along the long holes 41, ..., 41, and when appropriate tension is applied to the link chain 17, the fixing bolts 43, 41 for inserting the long holes 41 ,.
, 43 is tightened to fix the fixed guide 27 at that position and maintain the tension of the link chain 17. Connecting pin 1
5 slides along the outer circumference 45 of the fixed guide 27.

As shown in FIG. 2, the same mechanism as described above including the arm 13 for suspending and supporting the cage 11 and the endless link chain 17 is symmetrically arranged in front of and behind the apparatus with the cage 11 interposed therebetween. The respective endless link chains 17 arranged before and after this are interlocked by a main shaft 47 that drives the opposing upper sprocket wheels 23, 23 in a chain. The main shaft 47 rotates the drive chain 51, 51 wound around the drive sprocket wheels 49, 49 fixed coaxially with the upper sprocket wheels 23, 23, respectively, and applies the rotational drive force of the motor 53 to the speed reducer 55. Communicate through. Numerals 57 and 57 are idle wheels that clamp the drive chain 51 to adjust the tension and determine the orbit of the drive chain 51. In this embodiment, a motor is used as the driving force, but it is possible to use another driving source such as an engine.

As shown in FIG. 1, the upper sprocket wheel 23 supports the moments of the cages 11a and 11g located at the uppermost portion acting on the respective arms 13 by gravity together with the vehicles on which they are mounted.
Strictly speaking, the moment acting on the arm 13 in the section indicated by the arrow U is supported by the upper sprocket wheel 23. Further, the moments that the left cages 11b and 11c and the right cages 11e and 11f vertically guided by the guide rails 21 and 21 act on the respective arms 13 by gravity together with the vehicle on which they are mounted are the guide rollers 19 ,. Guide rails 21 and 21 through 19
Supported by. Strictly speaking, the moments acting on the arm 13 are supported by the guide rails 21, 21 via the guide rollers 19, ..., 19 in the sections indicated by the arrows R and L. Therefore, the link chain 1 in the section R-U-L
7 and the connecting pin 15 are loaded with only the tension in the longitudinal direction as a tangential force.

Since the cage 11d is in a naturally suspended state and the arms 13 are not restrained, the cage 11d and its mounting are mounted on the link chains 17 located below the respective arms 13 supporting the cages 11c and 11e. Due to the weight of the vehicle, a force acts to make the shape of the link chain 17 between the connecting pin 15a and the connecting pin 15b and between the connecting pin 15c and the connecting pin 15d close to a straight line on both sides of the arm 13 of the cage 11d. The fixed guide 27 supports this acting force on the circular arc of the outer periphery 45, and guides the guide rollers 19 and 19 of the arm 13 that move with the driving of the link chain 17 to the opening 59 of the guide rail 21.

Since the vertical component force exerted on the arc of the fixed guide 27 by the acting force of the link chain 17 is extremely small,
Frictional force is hardly generated between the link chain 17 and the fixed guide 27. Therefore, the movement of the link chain 17 is smooth and does not cause noise. That is,
Unlike the case where the lower sprocket wheel is used, there is no vibration or noise that is generated by the link colliding with the sprocket wheel due to looseness of the link chain.

When the vehicle is loaded or unloaded, the motor 53 is driven, the upper sprocket wheel 23 is rotated by the drive chain 51 through the reduction gear 55, and the link chain 17 is circulated to move the required cage 11. It is transferred to the position S shown in 1.

[0017]

According to the guide mechanism of the vertical circulation type parking apparatus of the present invention, the lower side in which endless link chains for suspending and supporting a plurality of vehicle-mounted cages are vertically stretched at intervals. Since the guide is formed in an arc shape as a fixed guide rail that does not rotate, the sprocket wheel, the sprocket wheel shaft and the bearing, which require a large amount of manufacturing cost, can be omitted, and the cost required for installation and alignment can be saved.
Further, vibrations and noises generated between the sprocket wheel and the link chain are reduced, and it can be suitably used in a residential area.
