Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to an improvement in a parking device for a motor vehicle.

[Conventional technology]

Figure 3 shows the conventional flat parking method, (a)
(b) is a plan view of a method of perpendicular parking and a method of parallel parking.

In the diagram, (1) is a parking lot, (2) is a road, (3) is a car,
(4) is an arrow indicating the movement of a parked car.

By the way, in order to park in a conventional parking lot, there are problems as described below.

■In case of right angle parking... Car to parking lot (1) (3)
To park your car, use the parking lot (1) and the road facing the entrance (2).
) must be at least 4m wide.

■Parallel parking not only requires skilled driving skills, but also requires approximately 0.8n of parking space.
, a car length of 1.5 meters is required and a large land area is required.

As mentioned above, in any case, parking requires a road facing the parking lot and a certain amount of space on both sides of the car, and also requires advanced driving skills. Securing a parking lot is often difficult both geographically and economically.

Based on the above circumstances, the applicant has previously filed a patent application filed in 1986-10.
In Publication No. 4944, a table parking device based on a new concept was proposed. Figures 4 to 6 show the parking device,
Figure 4 shows (a) a plan view and (b) a side view of the parking device;
The figure is an explanatory diagram of the operation, and FIG. 6 is a plan view (a) and a side view (b) of the wheel carrier.

As shown in the figure, the above-mentioned parking device is formed into a trapezoidal shape so as to be able to support the three wheels of the automobile on the upper surface, has wheels (6) on the lower surface, and has a rotating shaft (6) provided at one end of the vehicle body. A car carrier (5) that can rotate freely around the wheel (7), and a car support truck (5) that can rotate around the
It is composed of a wheel supporting carriage αB which supports the wheel (g) and is movable by means of wheels (2) provided on its lower surface.

When parking, the vehicle dolly (5) is rotated around the shaft (7) by human or mechanical power (not shown) in the direction of the road (2), and is positioned as shown in Figure 5. urge

Next, place the wheel carrier OD at the position shown in Fig. 5, drive the car in the direction of the arrow, load the three wheels a/D onto the vehicle carrier (5), and place the stopper (9). At the same time, for the remaining wheel 4, there is a concave portion α of the wheel holder OD.
Supported by j. Subsequently, the car receiving cart (5) is rotated in the opposite direction to the above, and is stored in the parking lot (1) as shown in FIG. 4, so that it is ready for parking. When taking out the car, move the car receiving cart (5) in the direction of the road in the same manner as above, let the car run from the cart (5), then move the cart (5) in the opposite direction and move it to the parking lot ( 1).

In addition, in the above-mentioned parking device, the reason why the car carrier is formed into a trapezoid is to avoid restrictions on the use of public roads when loading a car onto the car carrier.

[Problem that the invention seeks to solve]

By the way, in the above parking device, one of the wheels of the car (
The wheel support car QD that supports the wheel support car (g) is independent from the car support car (5), and when parking, the driver must get off the car and move the wheel support car αD to the planned position of the fourth wheel (to). It must be installed manually. This is a tedious task;
This was particularly disliked during rainy days, and improvements were desired.

The present invention was made in order to eliminate the drawbacks of the above-mentioned conventional devices.
The purpose is to provide a parking device that can be operated reliably and quickly without requiring much effort.

[Means for solving problems]

In order to achieve the above object, the parking device according to the present invention is provided with a car carrier that is formed so that three wheels of a car can be loaded on the upper surface thereof, and that is rotatable with a rotating shaft provided in a part of the car body; A shaft that engages with the vehicle support truck and is rotatable around the engaging portion and is extendable and retractable in the axial direction; and three shafts that are attached to the tip of the shaft and supported by the vehicle support truck of the automobile. The vehicle is comprised of a movable wheel support truck that supports a fourth wheel other than the wheels of the present invention.

[Effect]

Since the parking device is configured as described above, the wheel carrier that supports the fourth wheel of the automobile can be easily and quickly placed in a predetermined position according to the body dimensions of the automobile by extending/contracting and turning the shaft. This has made it possible to automate the operation.

[Embodiments of the invention]

FIG. 1 is a plan view (&) of a parking device showing an embodiment of the present invention, and FIG. 1(b) is an explanatory diagram of the operation. In the diagram, (1) is the parking lot, (2) is the road, (3) is the car, A4J, the car's wheels, (2) is the car carrier, (20m) is the wheel, C
! υ is the rotation axis, (2) is the shaft, (2) is the wheel holder, (2
3a) is the wheel.

As shown in the figure, the vehicle receiving trolley ■ is formed so that three wheels + 141 of a car can be loaded on the upper surface, three wheels (20a) are provided on the lower surface, and the vehicle is placed on the ground with the rotation axis r2IJ as the center. It is possible to rotate parallel to the A shaft (2) is attached to the vehicle support frame so as to be able to rotate by a certain angle, using a common rotating shaft c21+, and the shaft (2) is formed to be expandable and retractable in the axial direction. Further, a wheel holder (2) is attached to the tip of the shaft (2), and the wheel holder (2) is movable with wheels (23 ml) provided on its lower surface.

The parking device according to the present invention is configured as described above.

When parking, the vehicle receiving trolley ■ is turned in the direction of the road (2) as shown in Figure 2 by human or mechanical power (not shown), and then the shaft (shaft) is extended, contracted and turned, and the car's wheels are rotated. The wheel carrier (2) is arranged at a predetermined position in accordance with the base. Next, the car (3) is made to run, and its three wheels (Q4) are placed on the car carrier ■, and the fourth wheel (5)
is placed on the top of the wheel carrier (2), and the brakes are applied to the vehicle. Thereafter, the car holder xL■ is turned to its original position and stored in the parking lot (1). To start the car from the parking lot, repeat the same steps as above.

Note that when the wheel holder is not in use, the shaft can be shortened as shown by the dashed line in FIG. 1 so that it does not get in the way.

Further, as the mechanical power used for turning the car carrier (2), hydraulic pressure, electric motor, etc. may be used. Furthermore, the extension and contraction or rotation of the shaft may be performed mechanically using hydraulic pressure, an electric motor, or the like.

Although the above embodiment is an example in which the center of rotation of the shaft is made to coincide with the center of rotation of the vehicle receiving cart (2), it is not necessary to make the two coincide with each other. FIG. 2 is a plan view showing another embodiment in which the rotation axis C2D of the shaft (2) is different from that of the vehicle receiving truck (2).

As shown in the figure, a telescoping shaft (2) is attached to a part of the car cradle via the rotating shaft (2), and one end of the shaft is connected to a hydraulic cylinder attached to the car holder 4. Connect the axis
It is configured so that it can be rotated. A wheel holder is attached to the tip of the shaft (2), and the operation during parking is almost the same as that shown in FIG. 1.

In the embodiment shown in FIGS. 1 and 2 above, when the vehicle receiving cart (2) and the shaft (shaft) are operated by mechanical force,
Of course, it is also possible to automate the operation.

〔Effect of the invention〕

Since the parking device of the present invention is configured as described above, it has achieved excellent effects as described below.

■Parking space is small.

■Not subject to restrictions on use of public roads.

■When parking, the vehicle can be loaded onto the parking device reliably and quickly and moved into the parking lot.

■The wheel support car can be operated from the top of the car.

■Easy to automate.
