[Detailed description of the invention] [Industrial field of application] The present invention is an elevating multi-story parking system, in particular a structure in which the wheels always stop at a fixed position on the pallet.
The present invention relates to an elevating type multi-level parking device in which a driving motor is disposed in a space formed under a vehicle body to reduce the size of the device and to ensure reliable elevating and lowering operations.

[Conventional technology]

With the spread of automobiles, securing garages for storing automobiles has become a problem. In particular, in cities and their suburbs, it is necessary to make effective use of garage land due to land shortages, and elevating multi-level parking systems that can store two cars in one storage space are being considered. It's here.

As shown in FIG. 5, the conventional elevating type multilevel parking system merely has a car 10 mounted on a pallet 1 to form a two-story structure.

The elevating and lowering type multilevel parking system shown in FIG. 5 will be briefly explained as follows. That is, in the figure, reference numeral 1 is a pallet on which a car is mounted and is configured to be able to be raised and lowered, and 2 and 3 are

-1 is a lower end locking means provided near the lower end of the main pillar 3 to lock one end of the chain 4; 5-2 is provided near the upper end of the main pillar 2 to lock one end of the chain 4;
Upper end locking means for locking the other end; 6 is a motor; 7
9-1 to 9-3 are rotatable drive shafts that are equipped with a sprocket wheel (not shown) and are driven by the motor 6 through the sprocket wheel; Chain roller 10 represents a car mounted on pallet 1. The chain rollers 9-1 and 9-2 are fixedly and rotatably mounted on the pallet 1 and move together with the pallet 1. Also,
The chain roller 9-3 is fixedly and rotatably provided near the upper end of the main column 2. Although not shown, main pillars similar to the main pillars 2 and 3 are provided at positions facing the main pillars 2 and 3 with the pallet 1 in between, and the chain 4 and the lower end Stopping means 5-1, upper end locking means 5-2, drive shaft 7,
Chain rollers 9-1 to 9-3, etc. are provided symmetrically. Hereinafter, the operation of the vertical parking system shown in FIG. 4 will be briefly explained with reference to FIG. 5. Incidentally, reference numeral 9-4 in FIG. 5 denotes a sprocket which is fixed to the drive shaft 7 and meshes with the chain 4 to drive the chain 4.
It represents a foil, and the other symbols correspond to FIG. 4.

In FIG. 5, the center of gravity of pallet 1 is located at least to the right (in the direction of vehicle loading) of chain roller 9-2, as indicated by arrow W in the figure. The same applies if a car is installed). Therefore,
A force is acting on the pallet 1, centering on the chain roller 9-2, causing the right side to move downwards and the left side to rise upwards. However, the pallet 1 is supported by the chain 4 between the upper end locking means 5-2 and the chain roller 9-3 in the chain roller 9-2, and the lower end locking means 5-1 and the sprocket are supported by the chain 4 between the upper end locking means 5-2 and the chain roller 9-3. - It is supported in the opposite direction by the chain 4 between it and the foil 9-4 to keep it horizontal.

The pallet 1 is moved up and down by a motor 6. That is, the sprocket foil 9-4
is fixed to a drive shaft 7, and rotates when the drive shaft 7 is driven by the motor 6. And the above sprocket foil 9-4
When the direction of rotation is clockwise, the chain 4 is driven in the direction of arrow a in the figure and the pallet 1 is raised. In addition, the above sprocket foil 9-4
When the direction of rotation of chain 4 is counterclockwise,
is driven in the direction of arrow b in the figure, and the pallet 1 is lowered. In this case, the length of the chain 4 (between the lower end locking means 5-1 and the upper end locking means 5-2)
is constant, and for example, when the pallet 1 is raised, the upper end locking means 5-2 and the chain roller 9-
3 and the shortened length of the chain 4 between the lower end locking means 5-1 and the sprocket foil 9-4.
Because the lengths of chain 4 between
The pallet 1 is moved up and down while maintaining its horizontal state. Since the motor 6 is a so-called brake motor, the pallet 1 can be stopped at any desired position, ensuring its safety.

[Problem that the invention attempts to solve]

However, the conventional elevating type multilevel parking system simply places the car 10 on the pallet 1 as shown in Figure 5 and has a two-story structure, which has the disadvantage that it does not make effective use of land, which continues to rise in price. It was hot.

[Means for solving problems]

The purpose of this invention is to solve the above-mentioned drawbacks.The present invention has a structure in which the wheels of the automobile are always placed at a fixed position on the pallet, and the motor that is the driving source for moving the pallet in the vertical direction is connected to the automobile's wheel. It is an object of the present invention to provide an elevating type multi-level parking device which is disposed under the vehicle body and takes into consideration prevention of the chain from falling off which may occur due to the motor being disposed under the vehicle body of the vehicle. Therefore, the elevating multilevel parking system of the present invention includes a pallet on which a car is mounted, a drive shaft and a drive motor of a drive means for moving the pallet in the vertical direction, and the drive means moves the pallet into the parking system. In an elevating multilevel parking system configured to move up and down vertically along the main pillar of the vehicle, the vehicle is mounted on the pallet and the wheels of the vehicle are positioned at fixed positions on the pallet. At the bottom, the drive motor is disposed in a space formed under the body of the automobile at a position ahead of the tip of the pallet in the lowest position, and is mounted on the drive shaft. a drive chain stretched between the first sprocket and the second sprocket provided on the rotating shaft of the drive motor; and a horizontal section disposed at intervals above and below the first sprocket. The present invention is characterized in that it includes a drive chain fall prevention device having a horizontal portion disposed parallel to the drive shaft. This will be explained below with reference to the drawings.

Fig. 1 is a perspective view of a pallet of the elevating type parking device according to the present invention, Fig. 2 is a partial side view explaining the arrangement position of the driving part of the elevating type parking device according to the present invention, and Fig. 3 is a pallet perspective view of the elevating type parking device according to the present invention. FIG. 3 shows a side view of the drive chain fall-off prevention device.

In FIG. 1, numerals 2 and 3 correspond to those in FIGS. 4 and 5, and 11 represents a palette. At the tip of the pallet 11 on the side of the main pillar 3, there is provided a wheel positioning step 11-1 for placing the wheel in a fixed position, and a wheel stopper 12 for stopping the wheel is provided at the tip. When the car rides on the pallet 11 while moving forward and moves further forward, the front wheels of the car move over the wheel positioning step 11-.
1, whereby the driver recognizes that the vehicle has advanced to a predetermined position on the pallet 11. The wheel stopper 12 prevents the vehicle from moving further forward and separating from the pallet 11, and by stopping at this position, the center of gravity of the pallet 11 is located at a predetermined position. FIG. 2 shows the tip of the pallet 11 when the front wheels of the automobile fall into the wheel positioning step 11-1 and stop at a fixed position.

In FIG. 2, the symbols 2, 4, 5-1, 6,
7 and 10 correspond to those in Figures 4 and 5, and 6-
1 and 7-1 are sprockets, 13 is a drive chain, and 14 is a device for preventing the drive chain from falling off.

As explained in FIG.
1 and stops, the bonnet of the automobile 10 protrudes from the tip of the pallet 11 as shown in FIG. A space is created below the part. Since the driving motor 6 is installed in this space, the installation area can be reduced. Sprockets 6-1 provided on the drive motor 6 and drive shaft 7, respectively;
The drive chain 13 that transmits the driving force of the drive motor is wound around the pallet 11.
In order to raise and lower the
3 has slack. Due to this slack, when the drive motor 6 starts, the drive chain 1
3, damping occurs. In order to prevent the drive chain 13 from falling off, a drive chain fall prevention device 14 is provided near the drive chain 13 on the main column 2 or the mounting plate protection plate 15. The drive chain falling-off prevention device 14 is L-shaped as shown in FIG. 3, and the tip 14-1 of the L-shape is chamfered with a curve. Needless to say, the chain 4 intersects with the drive chain drop-off prevention device 14 at or near the tip 14-1. The distal end portion 14-1 of the drive chain drop-off prevention device 14 is disposed above the sprocket 7-1 at a distance and horizontally parallel to the axis of the drive shaft 7.

As shown in FIG. 2, in the present invention, the drive motor 6 is located to the right of the drive shaft 7 in the drawing. Under this arrangement of the driving motor 6, when the pallet 11 is in the lowest position as shown in the figure, the next pallet 1
When the driving motor 6 is rotated so as to raise the chain 1, the lower side of the drive chain 13 in the figure is stretched, and the upper side in the figure becomes slack.
When the drive motor 6 rotates, the illustrated rise of the drive chain 13 is damped due to the presence of the slack, and the drive chain 1
3 is likely to fall off from the sprocket 7-1.

Of course, the drive motor 6 is connected to the drive shaft 7.
If the drive chain 13 is placed on the left side in the drawing than the position shown in FIG. However, in the present invention, such an arrangement is not possible.

Based on the above reasons, the distal end portion 14-1 of the drive chain drop-off prevention device 14 is arranged horizontally as shown in the figure. As a result, even if the upper side of the drive chain 13 in the drawing becomes undesirably damped, the tip portion 14-1 prevents the drive chain 13 from undesirably damping.

Note that the tip portion 14-1 is chamfered appropriately so that the drive chain 13 can rotate smoothly even when it comes into contact with the tip portion 14-1 when the drive chain 13 vibrates. be made into

In addition, in the above explanation, it was explained that the front wheels of the car fall into the wheel positioning step 11-1 due to the positional relationship of the center of gravity of the pallet 11 on which the car 10 is mounted.
By taking into account the position of the center of gravity of the main pillars 2 and 3 and setting the positions of the main pillars 2 and 3 at an appropriate interval, it is possible to cause the rear wheels that have entered the vehicle in a backward state to fall into the wheel positioning step 11-1. Needless to say. At this time, just as when the front wheels are lowered onto the wheel positioning step 11-1, the elevating type multi-level parking system can be downsized and the parking lot can be used effectively.

[Effect of idea]

As explained above, according to the present invention, it is possible to downsize the elevating type multilevel parking system, making effective use of land, and reducing the length of the pallet, making the system inexpensive. Furthermore, the lifting and lowering operations are performed reliably and safety is ensured.
