Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage parking system.

[0002]

2. Description of the Related Art In recent years, with the increasing popularity of private cars, it has become common for homes that have two or more cars, but it is difficult to secure parking lots. Is. Therefore, various two-stage parking lot devices have been developed in order to solve the shortage of the parking lot. The applicant also previously filed Japanese Patent Application No. 3-263322 and Japanese Patent Application No. 4-269048.
Has filed an application for this type of device.

[0003]

By the way, in the above-mentioned two-stage parking lot apparatus, as shown in FIG. 5, the pallet 31 on which the vehicle is loaded has a power take-out roller built-in, so that the pallet 31 has a ground contact surface. However, it was necessary to provide an inclined plate 31a for climbing the step. For this reason, since a load is applied when climbing up the inclined plate 31a, it requires skill to operate the vehicle in order to smoothly mount the vehicle. In particular, it is difficult to mount the vehicle by laterally entering it, and in a vehicle model with a low vehicle height, the vehicle hits the side surface of the sloping plate 31a, which requires turning back and widthwise adjustment, which consumes a lot of time for mounting. There was fear. The present invention
In view of the above problems in the prior art, it is an object of the present invention to provide a two-stage parking lot device that can load a vehicle quickly and smoothly even with a simple driving technique.

[0004]

Therefore, according to the present invention, an outer frame, a rectangular vehicle-mounted pallet supported in the outer frame in a horizontal state and vertically movable, and connected to the pallet, the pallet And a drive mechanism for moving the drive mechanism up and down, and a power take-out roller rotatably mounted on the pallet, which rotates following the rotation of the drive wheels of the vehicle and operates the drive mechanism by its rotational force. In the stepped parking device, the vehicle-mounted pallet is provided in a flat plate shape, and an inclined portion is provided immediately before the power take-out roller,
Cover the upper surface of the power take-off roller from the upper end of the inclined portion
In addition, the extending portion is provided by changing the angle from the apex of the inclined portion .

[0005]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a two-stage parking apparatus according to the present invention, FIG. 2 is a side view of FIG. 1, FIGS. 3 (a) and 3 (b) are cross-sectional views of an inclined plate, and FIG. 4 is another pallet for mounting on a vehicle. 5 is a perspective view of a conventional two-stage parking apparatus. As shown in FIGS. 1 and 2, columns 4a, 2b, 2c, and 2d, which are outer frames, are erected at four corners of a rectangular base 1, and the columns 2a, 2b, 2c, and A pallet 3 for mounting on a vehicle is horizontally supported by 2d and is vertically movable. Here, the pallet 3 has a flat plate shape, and frame bodies 4 and 5 are integrally provided on both sides thereof. A guide roller 6 is rotatably attached to the front and rear of the frame bodies 4 and 5, and vertical columns 7 are formed on the columns 2a, 2b, 2c, and 2d on the surface facing the guide roller 6. By inserting the guide roller 6 into the vertical groove 7, the pallet 3 is moved to the columns 2a, 2b, 2c, and 2
It is supported so as to be vertically movable with respect to d. Further, hydraulic cylinders 8 and 9 are erected on both sides of the pallet 3 on the base 1, and the hydraulic cylinders 8 and 9 are erected.
The tips of the rods 8a and 9a are fixed to the upper ends of the frames 4 and 5. Thus, if the rods 8a and 9a of the hydraulic cylinders 8 and 9 are sucked from the state shown in FIG. 1, the pallet 3 can be lowered toward the base 1.

The pallet 3 is formed in a flat plate shape, and two power take-off rollers 12 and 13 are horizontally provided in the rear portion of the pallet 3 in the lateral direction of the pallet 3. Here, the power take-off rollers 12 and 13 are in a state in which only rotation in one direction (counterclockwise in FIG. 2) is allowed, and rotation in the opposite direction is locked. A hydraulic pump 10 is attached to the rear portion of the pallet 3, and the hydraulic pump 10 is connected to a power take-out roller 13 via a chain 10a. As a result, the drive wheels 14 of the vehicle (rear wheels in this embodiment)
When the drive wheel 14 is rotated (clockwise in FIG. 2) with the power bearing rollers 12 and 13 mounted on the drive wheel 14,
The power take-off rollers 12 and 13 rotate counterclockwise so that the power take-off roller 13 is rotated by the hydraulic pump 1.
It can be transmitted to 0.

Power take-out roller 12 on pallet 3
Immediately before, the inclined plate 1 is covered with a part of the upper surface of the power take-out roller 12 as shown in FIGS.
1 is provided, and a horizontal extending portion 11 is provided from the upper end thereof.
a or an extending portion 11 having an inclination opposite to that of the inclined plate 11
b is provided so that the drive wheels can be mounted between the power take-off rollers 12 and 13 by mounting them.

As shown in FIGS. 1 and 2, the hydraulic pump 10 is connected via a hydraulic rubber hose 10b to a hydraulic unit 15 including an ascending / descending speed adjusting valve, and the hydraulic unit 15 is connected to the hydraulic cylinders 8 and 9. Are linked to. As a result, the pallet 3 can be lifted by driving the hydraulic pump 10 and extending the rods 8a and 9a of the hydraulic cylinders 8 and 9 as described above. Further, an operation lever 16 is interposed between the hydraulic pump 10 and the hydraulic unit 15, and by operating the operation lever 16 to gradually release the pressure in the hydraulic cylinders 8 and 9, the rods 8a and 9a are removed. Is sucked and the pallet 3 can be lowered.

Next, the operation of this embodiment will be described. According to the two-stage parking apparatus of the present embodiment, since the pallet 3 is provided in a flat plate shape, the step with respect to the ground contact surface can be ignored and the entering direction of the vehicle is not restricted. Further, the weight of the pallet 3 can be reduced, the power required for raising and lowering the pallet 3 can be small, and the load on the pallet 3 can be increased with the same power. Further, since the inclined plate 11 is provided immediately before the power take-off roller 12, and the upper end of the inclined plate 11 covers a part of the upper surface of the power take-out roller 12 and the extending portion 11a or 11b having a horizontal or reverse inclination is provided. , The driver can sense the position of the wheels. As a result, the drive wheel 14 can be safely and reliably put in between the power take-off rollers 12 and 13 and placed. In the above embodiment, the inclined plate 11 is mounted on the pallet 3 to provide the inclined portion, but the pallet 32 may be bent to integrally form the inclined portion as shown in FIG. .

[0010]

As described above, the present invention has the following excellent effects. (1). Since the step between the vehicle pallet and the ground contact surface can be ignored and the vehicle's approach direction is not restricted,
Vehicles can be loaded quickly and smoothly even with simple driving techniques. (2). When riding the drive wheels of the vehicle on the power take-off roller, the driver can sense that the drive wheels are in the position immediately before the power take-off roller, and can get on safely and reliably.
