Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking device, and in particular, it is conventionally possible to park a vehicle by moving it from a road to a storage place while avoiding a fence or a similar structure while the vehicle is placed on the parking device. The present invention relates to an obstacle avoidance type parking device configured to allow parking even in a place where it was impossible at all.

[0002]

BACKGROUND OF THE INVENTION AND PRIOR ART Due to the recent increase in the number of vehicles, the shortage of parking space is in a critical situation mainly in urban areas. As one of the solutions, large and small parking spaces that efficiently use space are available. Various facilities have been proposed and used. Of these, a small parking device that accommodates one or two vehicles has recently been attracting attention as a small-scale business office or for personal use, and the number of shipments thereof is increasing.

[0003]

The basic structure of the parking device for two vehicles is such that one vehicle is lifted by the lifting plate, and another vehicle is accommodated in the lower space created by this, so that one vehicle It is characterized by being configured to park two vehicles in a parking space. FIG. 5 is a plan view of this conventional two-vehicle parking apparatus, in which the vehicle C is placed with the elevator 101 supported by a pair of support pillars 100, 100 standing upright from the ground, being lowered. Lifting stand 1
After raising 01, another vehicle is put in the space formed in the lower part so that two vehicles can be parked in a space substantially equal to the parking space for one vehicle.

Since this device is simple in structure and can be manufactured at a relatively low cost, it is currently widely used for small-lot use.
On the other hand, there are the following problems.

When it is desired to take out the upper car when two cars are parked, first the lower car is moved to another place, then the upper car is lowered and moved to another place, and further ahead. I had to move it and put the car underneath it on a moving platform to raise it,
Getting in and out of the car is quite troublesome. In addition, it is a problem that it is necessary to move one vehicle somewhere to park the vehicle, although it is a device introduced because it is originally difficult to secure a parking space.

Further, when the device is arranged in a vacant space between the adjacent doors H as shown in the figure, the installation width including the space for the inner ring difference required for the vehicle C to enter the lift 101 and the space for the turning back is added. Since W is required, the parking device installation space alone is not sufficient for parking. Further, as a matter of course, if there is an outdoor installation such as the storage 102 in the parking space, it is impossible to install the parking device without removing the outdoor installation.

Here, as the installation condition of the parking device, there is at least one parking space for its structure because of its structure, and an inner ring differential and a turning space for allowing a vehicle to enter the parking device. There is a prerequisite. However, in recent urban circumstances, it is becoming difficult to secure such a small space. In such a pressing environment, it would be extremely convenient if a space that could not be used as a parking space in the past can be used as a parking space.

For example, when it is considered as a parking space, there is no turning space, or, for example, an outdoor unit such as an air conditioner is installed, such as the above-mentioned shed, and a fence made of concrete blocks or concrete panels. It would be extremely effective if a space that was originally unusable as a parking space could be used as a parking space because a partition structure is installed. In response to such a request, a parking device of a type in which a link mechanism is composed of a plurality of arms to move a vehicle in and out has an advantage that it is not necessary to turn the parked vehicle. An example of this arm type parking device is Japanese Patent Laid-Open No. 63-41.
76, JP-A-64-1873, and JP-A-63-671.
No. 56 is proposed. Although all of these configurations have the above advantages, it is not possible to store the vehicle by avoiding obstacles such as fences, because the arm is not configured to operate by avoiding obstacles. Is.

SUMMARY OF THE INVENTION The present invention is an apparatus constructed in view of the above-mentioned problems of the prior art and the above-mentioned demands, and a mounting table on which a vehicle is mounted, and the mounting table for raising and lowering the mounting table. And a mechanism for moving the mounting table in a horizontal direction corresponding to the above, and a mechanism for raising and lowering the mounting table is configured to be operable while avoiding various obstacles such as the block wall. It is a parking device.

[0010]

The first arm and the second arm, which are drive mechanisms for vertically moving the mounting table for mounting the vehicle, are formed in a substantially "U" shape and a substantially "L" shape, respectively, and are at the lowest position. When the vehicle is placed on a certain mounting table, the mounting table is lifted while the horizontal state is maintained by the rotating operation of the first and second arms. During this time, the obstacles such as the block wall and the air conditioner outdoor unit, which are located close to the parking device, are the first and the second.
When the arms of the vehicle are rotated, they will be located at the bent portions of these arms, so that the operation of the drive mechanism will not be obstructed by these obstacles, and therefore the vehicle in / out should avoid these obstacles. It will be done smoothly.

[0011]

Embodiments of the present invention will be specifically described below with reference to the drawings.

1 to 4 show an embodiment of the present invention. First, the details of the configuration of the parking device of the present application will be described mainly with reference to FIGS. 1 and 2.

Numerals 1A and 1B are columns that support the entire apparatus, and are firmly constructed to support the weight of the entire apparatus and the weight of the mounted vehicle body. These pillars 1
As shown in FIG. 2, A and 1B are arranged to face each other, and both are fixed to the ground with sufficient strength. Although a mechanism for raising and lowering the vehicle C is provided for each of the columns 1A and 1B, the mechanism provided to the column 1A will be mainly described below as an example.

Reference numeral 2 denotes an arm (hereinafter referred to as a "first arm") rotatably provided with a rotation shaft 4 with respect to the inside of the column 1A, that is, the side facing the other column 1B.
Reference numeral 0 is a geared motor for rotating the first arm 2 connected to the rotary shaft 4. Reference numeral 3 denotes another arm (hereinafter referred to as a "second arm") which is located above the first arm 2 and is rotatably provided on the outer side of the support column 1A with a rotation shaft 5. Of these two arms, the first arm 2 is shown in FIG.
As shown in FIG. 3, the arms are formed to be bent so that both ends of the arms are opposed to each other through the open space 14, and the side surface is formed to have a substantially “U” shape.

On the other hand, the second arm 3 is bent and formed at about 90 ° in the substantially central portion of the arm, and the entire side surface is formed in a substantially "L" shape.

Reference numeral 6 is a mounting table on which the vehicle C is mounted.
Since the vehicle C is arranged in this device so that the front and rear faces the columns 1A and 1B, the entire length of the mounting table 6 (the column 1
The length in the A and 1B directions) is formed to be slightly longer than the entire length of the vehicle C. Reference numerals 7 and 7 denote support members firmly attached to both ends of the mounting table 6 so as to be orthogonal to the mounting table 6. The end of the arm of the first arm 2 that faces the mounting portion of the rotary shaft 4 through the open space 14 is attached to the lower portion of the support member 7 with the rotary shaft 8, that is, the mounting portion of the mounting table 6 or its vicinity. It is rotatably attached. On the other hand, the end of the second arm 3 facing the mounting portion of the rotary shaft 5 is rotatably connected to the upper portion of the support member 7 via a long rotary shaft 9.

With the above construction, the rotary shafts 5, 4, 8, 9
A parallelogram 11 (see FIG. 1) is formed by an imaginary line connecting the two, and the first and second arms 2 and 3 form a parallel link. The arms provided on the support 1A are symmetrically attached to the other support 1B as shown in FIG. 2, and the mounting table 6 including the support member 7 is mounted on the mounting table 6 including the pair of first arms 2, 2 and the second arm. It has a configuration in which it is arranged across 3 and 3.

Next, the operating state of the parking device described above will be described.

First, FIG. 1 shows a position where the vehicle C is stored (parked), and its operation will be described by showing a state where the vehicle C is lowered to a position where the vehicle can start.

First, a geared motor 10 is rotated by turning on a switch (not shown). The gear ratio of the geared motor 10 is set to be high so that the geared motor 10 rotates slowly with a strong torque. This geared motor 1
The rotational force of 0 is transmitted to the first arm 2 via the rotation shaft 4, whereby the first arm 2 starts rotating in the X direction of FIG. This rotation is transmitted to the second arm 3 via the rotation shaft 8, the support member 7, and the rotation shaft 9, and the second arm 3 also rotates in the X direction in synchronization with the first arm 2. As the two arms 2 and 3 rotate, the mounting table 6 connected to the rotary arms 2 and 3 via the support member 7 descends as shown in FIG. 3, and the plane projection position 12 thereof is indicated by an arrow Y in response to the descending operation. As shown in FIG. 4, the plate is displaced to the right side of the drawing and horizontally moved, and finally arranged at the position shown in FIG.

In the above case, as described above, the rotary shafts 5, 4,
A parallelogram 11 can be assumed between 8 and 9, and parallel sides 5-4 and 9-8 are always positioned vertically, and the mounting table 6 is disposed so as to be orthogonal to the side 9-8. Therefore, the mounting table 6 has the first arm 2 and the second arm 3
The horizontal position of the vehicle C is always maintained irrespective of the rotation of the vehicle, and the vehicle C placed thereon also moves up and down while maintaining the horizontal state. Since the vehicle C that has been lowered onto the traveling road portion such as a road is arranged at a position along the traveling road in this state, it can be started as it is without changing the direction. During parking, the above operations are performed in reverse order in the order of FIG. 4, FIG. 3, and FIG.

In the above-described operation, the lower first arm 2 is bent in a substantially "U" shape, and the second arm 3 is formed in a substantially "L" shape. Figure 3,
Even if there are obstacles such as the fence 13 adjacent to each other as shown in FIG. 4, these obstacles are located in the open space 14 of the first arm 2 and the bent portion space of the second arm 3 as shown in FIG. These obstacles have no influence on the operation of the device as long as they have a shape and size that allow the vehicle to be moved in and out freely. That is, it becomes possible to use a space that has not been considered as a parking space in the past, as a parking space, such as being able to park over a fence.

When the vehicle C is placed at the parking position as shown in FIG. 1, a completely free space is sufficiently provided below the vehicle C so that each part of the marginal device does not temporarily occupy the space during the operation of the device. Therefore, an installation object such as a storeroom may be arranged in this space. Further, as shown in FIG. 4, it becomes possible to park even in a place where the direction cannot be changed and the conventional parking is impossible at all, such as a narrow alley in which another fence 13 'is arranged in close proximity to the fence 13. .

In the structure shown, the geared motor 10 is used.
Was installed only on the support 1A side, but was also installed on the support 1B side,
It is also possible to increase the driving force by configuring both motors to operate synchronously.

[0025]

As described in detail above, the present invention has the following advantages.
Since the first arm and the second arm, which are driving mechanisms for driving the mounting table up and down, are formed in a substantially "U" shape and a substantially "L" shape, respectively, there are obstacles such as a block fence and an air conditioner outdoor unit. Even if the obstacle is located in the bent space of each arm when the mounting table descends, the obstacle can be avoided and the vehicle can be taken in and out. It can be used as.
