[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile parking device for a motor vehicle, and more particularly to a motor vehicle parking device which rotates a driving wheel of the motor vehicle independently of the operation of a steering device of the motor vehicle, for example, at right angles to the traveling direction of the vehicle. The present invention relates to a mobile parking device that can move laterally and park at a predetermined position.

[0002]

2. Description of the Related Art Recently, various parking devices have been proposed and used for parking an automobile in a limited space. For example, a multi-story parking device that raises and lowers a car in the vertical direction in order to expand a parking space is used. This requires not only means for raising and lowering but also means for moving or rotating the car in a horizontal direction, and is relatively large. Device. On the other hand, there have been proposed various parking devices that move or rotate in the horizontal direction without moving up and down. As a parking device that moves in the horizontal direction, the wheels of the vehicle are mounted on a bogie or the like, and can be moved in a horizontal direction perpendicular to the traveling direction of the vehicle without steering the vehicle, and There has been proposed a configuration in which the vehicle can be parked in a parking lot having a mouth for a slightly longer time than the length of the parking lot.

For example, Japanese Utility Model Laid-Open No. 48-10183 discloses that
The vehicle has a pair of rollers that engage with the driving wheels of the vehicle. One of the rollers is driven to rotate by the driving wheels, and the driving force is transmitted to the wheels provided on the bogie so as to be substantially perpendicular to the traveling direction of the vehicle. Has been proposed. Japanese Utility Model Application Laid-Open No. 53-70587 discloses a transmission mechanism for transmitting the rotational force of a roller to at least one of the carts and a roller stopper device for fixing the rollers. There has been proposed an automobile moving device in which wheels of a bogie are rotated via rollers and a transmission mechanism. In this publication, a transmission mechanism for transmitting the rotational force of one roller to the other roller is provided, and each of the rollers is configured to be rotationally driven by driving wheels of an automobile. Furthermore,
Japanese Utility Model Laid-Open Publication No. 52-86188 discloses an automobile storage cart having a pair of rollers provided on an underframe, and a traversing wheel being rotationally driven by a driving wheel of the automobile via a power transmission mechanism. The driving force is transmitted from the two rollers to the traversing wheel.

[0004]

Any of the mobile parking devices disclosed in the above publications have a roller and a power transmission mechanism for transmitting the driving force of the driving wheels of the vehicle to the wheels of the bogie, and some of the mobile parking devices have a power transmission mechanism. Except for the conventional device, a mechanism is provided for stopping the rotation of the rollers or wheels of the truck so as to be able to escape from the truck after moving to a predetermined position.

However, in any of the mobile parking devices disclosed in the above publications, when the wheels of the bogie stop, as in the case where the bogie or its wheels are hit by an obstacle to hinder the movement of the bogie, If the roller connected thereto locks, the driving wheel of the vehicle may get over the roller and separate from the bogie. To cope with this, it is necessary to adjust the driving force of the vehicle according to the locked state of the rollers, but it is difficult to adjust the driving force at this time, and it requires skill in the moving operation, and the driving wheel is inadvertently operated due to erroneous operation. There is a possibility that it will be detached from the cart.

In order to prevent this, Japanese Utility Model Laid-Open Publication No. 52-861
No. 88 and Japanese Utility Model Application Laid-Open No. 53-70587 have a car stop on the driven wheel side of an automobile, but the attaching and detaching work is complicated. In addition, if the driving force of the driving wheels increases, there is a possibility that the vehicle may get over the vehicle stop, and in such a case, the vehicle separates from the bogie at a considerable speed. Further, Japanese Utility Model Laid-Open No. 48-10183 discloses an embodiment in which a shaft pin is provided on a driven wheel side of an automobile and is rotated about the shaft pin. ,
When the carriage or its wheels are hit by an obstacle and the movement of the carriage is prevented, the driving wheels of the vehicle may be detached from the carriage, and it is difficult to put into practical use.

Accordingly, the present invention provides a mobile parking device in which a driving wheel of an automobile is mounted on a pair of rollers provided on a support base, and the driving wheel is rotated to move the automobile in a predetermined direction and park at a predetermined position. An object of the present invention is to provide a mobile parking device capable of moving a support base in a predetermined direction while supporting a driving wheel on a roller in a stable state regardless of a rotation direction of the driving wheel.

It may be configured to be connected to the wheel of the first support, and to rotate the wheel of the second support in accordance with the rotation of the wheel of the first support.

[0017]

In the mobile parking device having the above-mentioned structure, the driving wheel of the automobile rides on the support table and is mounted on the first and second rollers. At this time, the second roller is arranged, for example, on the rear side of the vehicle. In this state,
After releasing the rotation stop state of the first roller or the second roller by the stopping means, for example, when the driving wheels are driven to rotate in the direction in which the automobile moves backward, both the first and second rollers rotate the driving wheels. It is driven in a direction opposite to the direction, but the rotation directions of the first and second rollers at this time are assumed to be normal rotation. That is, when the first roller and the second roller are both driven to rotate forward when the second roller is located on the rear side of the vehicle, the first one-way rotation restricting means causes the first unidirectional rotation restricting means to rotate the first roller.
The rotational force of the roller is transmitted to the wheels of the support table via the rotation transmission mechanism, whereas the second roller idles and is not transmitted by the second one-way rotation restricting means. Conversely, when the driving wheel is driven to rotate forward in the direction in which the automobile moves forward, the first and second rollers are both driven to rotate in the reverse direction. In this case, the first roller is controlled to rotate in the first one-way direction. The second roller is idled by the means, and the rotational force of the second roller is transmitted to the wheels of the support base via the rotation transmission mechanism by the second one-way rotation restricting means.

Therefore, when the movement of the support table is prevented during both forward and reverse rotations of the first and second rollers, the first roller located on the forward or rearward traveling direction side of the vehicle. Since the roller or the second roller can be set in a positional relationship in which the roller idles, the drive wheel does not separate from the support base. When the drive wheel is to escape from the support table, if the rotation of the drive wheel is stopped after the rotation of the first roller or the second roller positioned in the escape direction is stopped by the stopping means, the drive wheel stops at the predetermined position. Since the driving force is applied to the support table in the state in which the drive wheel escapes, the drive wheels can be easily released from the support table. The other drive wheels and driven wheels of the vehicle are mounted on another support base that rotatably supports the wheels, for example, but the vehicle is mounted on one support base exposing the first and second rollers. All the wheels may be mounted and the vehicle may be supported so as to be movable in accordance with the movement of the support base by the rotation drive of the drive wheels.

By rotating and driving the drive wheels of the automobile, the rotational force of the first roller or the second roller is transmitted to the wheels of the support base on which the drive wheels are mounted, and the wheels rotate. When driven, the vehicle moves in a predetermined direction, for example, a direction perpendicular to the traveling direction of the vehicle. The vehicle can be moved in any direction by appropriately changing the mounting angle of the wheel with respect to the support base.

In a mobile parking device that supports a car so as to be able to turn around one support shaft, the driving wheels are supported on the first and second rollers in a stable state as described above, and In response to the rotation of the first and second rollers by the rotation of the wheels, the vehicle turns around the support shaft and moves to a predetermined position.

As the first and second one-way rotation restricting means, first and second one-way clutch mechanisms can be used, respectively. When the first roller reversely rotates, the rotational force is transmitted, and the first roller reversely rotates and the second roller rotates forward when the second roller rotates forward.

In a mobile parking device using a main rotating member and first and second rotating members, a driving wheel is mounted on first and second rollers. At this time, the second roller is arranged, for example, on the rear side of the vehicle. In this state, when the rotation stop state of the first roller or the second roller by the stopping means is released and, for example, the driving wheels are driven to rotate in the direction in which the automobile moves backward, both the first and second rollers are driven. It is driven in a direction opposite to the rotation direction of the wheel. The rotation directions of the first and second rollers at this time are assumed to be normal rotation. Thus, when the first and second rollers are both driven to rotate forward, the main rotating member and the first rotating member urged in the direction to engage with the first roller maintain the engaged state. Then, the rotational force of the first roller is transmitted to the wheels of the support base via the first rotating member and the main rotating member. At this time,
The rotational force of the second roller does not substantially contribute to the rotation of the wheel of the support base. When both the first and second rollers are driven to rotate forward when the main rotating member is substantially stopped, the first rotating member is engaged with the main rotating member and the first roller. While being maintained, the second rotating member is driven by the rotating force of the second roller in a direction to separate from the main rotating member and the second roller against the biasing force of the second biasing means, and The second roller idles without transmitting its rotational force to the main rotating member.

On the other hand, when the first and second rollers are both driven to rotate in reverse, the second rotating member is maintained in the engaged state with the main rotating member and the second roller, and The torque is transmitted to the wheel of the support via the second rotating member and the main rotating member, but the torque of the first roller does not substantially contribute to the rotation of the wheel of the support. If the first and second rollers are both driven to rotate reversely when the main rotating member is substantially stopped, the state in which the second rotating member is engaged with the main rotating member and the second roller is maintained. But the first
Is driven in a direction to separate from the main rotating member and the second roller by the rotational force of the first roller against the urging force of the first urging means, and the first roller is rotated by the rotational force of the first roller. Idles without being transmitted to the main rotating member. If the rotation of the drive wheel is stopped after the rotation of the first roller or the second roller positioned in the direction in which the drive wheel escapes from the support base is stopped by the lock mechanism, the support base stopped at a predetermined position. Since the driving force in the direction of escaping from the support wheels is transmitted, the drive wheels can easily escape from the support base.

In the apparatus using a gear as the rotating member, for example, when both the first and second rollers are driven to rotate forward, the gear constituting the first rotating member becomes the main gear and the first gear. The state of meshing with the gear of the roller is maintained, and the rotational force of the first roller is transmitted to the wheel of the support base via the gear and the main gear that constitute the first rotating member. At this time, the second
Does not substantially contribute to the rotation of the wheels of the support base. When the first gear and the second roller are both driven to rotate forward when the main gear is substantially stopped, the gear constituting the first rotating member engages with the main gear and the first roller. While the state is maintained, the gear constituting the second rotating member is driven by the rotating force of the second roller in a direction to disengage with the main gear against the urging force of the second urging means. The second roller idles without transmitting its rotational force to the main gear. On the other hand, when the first and second rollers are both driven to rotate in reverse, the gear forming the second rotating member is kept in mesh with the main gear and the gear of the second roller. Does not substantially contribute to the rotation of the wheels of the support base. When the first gear and the second roller are driven to rotate in reverse when the main gear is substantially stopped, the gear constituting the second rotating member is engaged with the main gear and the second roller. Is maintained, but the first roller idles. If the lock mechanism is engaged with a gear provided on the first or second roller, the rotation of the first or second roller is prevented.

In an apparatus provided with a main gear and first to sixth gears, for example, when both the first and second rollers are driven to rotate forward, the fifth gear becomes the main gear and the third gear. The state of meshing with the gears is maintained, and the rotational force of the first roller is transmitted to the wheels of the support via the first gear, the third gear, the fifth gear, and the main gear. At this time, the rotational force of the second roller does not substantially contribute to the rotation of the wheel of the support base.
When the main gear is substantially stopped, the first and second
When both rollers are driven to rotate forward, the fifth gear is kept in mesh with the main gear and the third gear, but the sixth gear is rotated by the rotational force of the second roller. The gear is driven in a direction to disengage the main gear and the fourth gear against the own weight of the gear, and the second roller idles without transmitting its rotational force to the main gear. On the other hand, when the first and second rollers are both driven to rotate in reverse, the state where the sixth gear meshes with the main gear and the fourth gear is maintained, and the rotational force of the second roller is reduced by the rotation of the support base. Although transmitted to the wheels, the rotational force of the first roller does not substantially contribute to the rotation of the wheels of the support. When the first gear and the second roller are both driven to rotate reversely when the main gear is substantially stopped, the state where the sixth gear meshes with the main gear and the fourth gear is maintained, The first roller idles.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 relate to an embodiment of the mobile parking device of the present invention, and FIG. 1 shows the entire configuration of the mobile parking device.
In FIG. 1, support frames 1 and 2 each having a substantially rectangular shape in a plan view are detachably connected to both arms of a connecting member 5 having a T-shape in a plan view, and support frames 3 and 4 each having a rectangular shape in a plan view have a T-shape.

In this embodiment, the members constituting the support frame 1 and the like are mainly constituted by pipes having a rectangular cross section to reduce the weight. However, solid bars may be used.

The support frame 1 constitutes a support base according to the present invention. As shown in FIG. 2 to FIG. 4, a member 1a on one side is formed in a box shape having an opening on the bottom surface. It has a structure capable of accommodating a rotation transmission mechanism 50 described later and the like. The other members 1b, 1c, 1d are constituted by tubes having a rectangular cross section. Wheels 61 to 63 are supported in the member 1a and in the middle part on the outside of the member 1b opposed thereto so as to be rotatable about axes in the same direction. Further, a first roller 10 and a second roller 20 are arranged in the support frame 1, that is, in a frame surrounded by the members 1 a to 1 d, at a predetermined distance in parallel with each other, and both ends thereof are arranged at both ends. Member 1a, 1
b is rotatably supported. On the first and second rollers 10 and 20, a driving wheel DW1 on one side of the wheels of the automobile is mounted as indicated by a two-dot chain line so as to rotate around an axis parallel to these rotation axes. The first and second rollers 10 and 20 are configured to be frictionally engaged with each other.

Spur gears 51 and 52 are fixed to one shaft end of each of the first and second rollers 10 and 20. Further, in the member 1a of the support frame 1, a spur gear 53 is rotated around an axis parallel to the axes of the spur gears 51 and 52 at the center between the support portions of the first and second rollers 10 and 20. It is movably supported, and a bevel gear 54 is integrally joined to the spur gear 53. On the other hand, the wheels 61 and 62
The shaft 60 is rotatably supported by the member 1 a on an axis orthogonal to the axis of the bevel gear 54, that is, the axis orthogonal to the rotation axes of the first and second rollers 10 and 20. . A bevel gear 55 is fixed to a central portion of the shaft 60 so as to mesh with the bevel gear 54, and the wheels 61, 62 rotate around an axis orthogonal to the rotation axis thereof according to the rotation of the spur gear 53.
Are arranged to rotate.

Further, as shown in FIG.
A spur gear 31 pivotally supported so as to be able to rotate around an axis parallel to each of the rotation shafts 3 is urged by a spring 33 in a direction in which it meshes with the spur gears 51 and 53. Similarly, the spur gear 32 is urged by a spring 34 in a direction to mesh with the spur gears 52 and 53. That is, the base ends of the arm members 35 and 36 are swingably supported by the rotation shafts of the spur gears 51 and 52, respectively.
The spur gears 31 and 32 are rotatably supported at the tips of the springs, respectively, and one ends of springs 33 and 34 are fixed. The other ends of the springs 33 and 34 are connected to the support frame 1.
2 is fixed to the upper surface (upper side in FIG. 2) of the member 1a
1, 32 are spur gears 51 and 53, spur gears 52 and 5, respectively.
3 is urged in the direction of engagement from below in FIG. Note that the base ends of the arm members 35 and 36 may be swingably supported on the rotation shaft of the spur gear 53. Further, the base ends of the arm members 35 and 36 are set in a free state, and the spring 3
It may be supported by 3, 34 and urged in a predetermined direction.

Therefore, the rotation transmission mechanism 50 is constituted by the spur gear and the bevel gear, and normally the spur gear 5
The spur gears 1 and 52 are in mesh with the spur gear 53 via the spur gears 31 and 32, and when the spur gears 51 and 52 are driven to rotate counterclockwise in FIG. 2, for example, the spur gear 53 also rotates counterclockwise. However, the rotational force of the spur gear 51 is not transmitted to the spur gear 53 and is substantially in an idling state (this relationship will be described in detail in the operation description below). For example, when the spur gear 53 is in a substantially stopped state, the spur gears 51 and 52
When the spur gear 32 is driven to rotate counterclockwise, the spur gear 32 is driven in a direction in which it meshes with the spur gears 52 and 53.
2, 32, 53 mesh with each other and are connected.
1 is driven counterclockwise around the rotation axis of the spur gear 51 against the urging force of the spring 33 together with the arm member 35, the engagement of the spur gear 31 and the spur gear 53 is released, and the spur gear 31 idles. I do. On the other hand, for example, when the spur gears 53 are substantially stopped and the spur gears 51 and 52 are driven to rotate clockwise in FIG. 2, the spur gear 31 is driven in a direction in which the spur gears 51 and 53 mesh with each other. Accordingly, the spur gears 51, 31, and 53 mesh with each other and are connected to each other. The spur gear 32 is driven clockwise about the rotation axis of the spur gear 52 against the urging force of the spring 34 together with the arm member 36. The engagement between the spur gear 32 and the spur gear 53 is released, and the spur gear 32 idles.

As described above, the spur gear 31 or the spur gear 3
2 are engaged with the spur gears 51 and 53 or the spur gears 52 and 53, respectively, and the rotational force of the first roller 10 is
1 or 62, or the rotational force of the second roller 20 is transmitted to the wheels 61 and 62 so that the support frame 1 moves in a predetermined direction. Further, on the second roller 20 side, a lock mechanism 70 is provided as a stopping means capable of stopping the rotation. This lock mechanism 70
A hook portion 72 is formed at the tip of the operation lever 71, and an intermediate portion is pivotally supported by the member 1 a of the support frame 1.
By rotating the hook 1 about the shaft 73 in the clockwise direction in FIG. 2, the hook 72 can be engaged with the teeth of the spur gear 52. The lock mechanism 70 may be provided on the side of the spur gear 51 or may be provided on both sides.

On the other hand, the support frame 2 shown in FIG. 1 is provided with rods 11 and 21 parallel to each other.
The drive wheels DW2 on the other side are arranged to be mounted on the drive wheels 1 and 21, but are fixed to the support frame 2 so as to prevent the drive wheels DW2 from rotating even when driven.
In addition, the support frame 2 can rotate around an axis perpendicular to the axes of the rods 11 and 21, that is, an axis parallel to the rotation axes of the wheels 61 to 63, at the outer intermediate portion of the opposed members 2 a and 2 b. Wheels 64 and 65 are supported as described above.

Each of the support frames 3 and 4 has a pair of wheels arranged in the longitudinal direction, and is supported so as to be rotatable around an axis parallel to the rotation axis of the wheels 61 to 65.
FIG. 1 shows a state in which these wheels are covered by covers 84 to 87. Although not shown, the wheels 6
3 to 65 are also covered by similar covers. Thus,
The driven wheels FW1 and FW2 of the vehicle are provided with covers 84 and 8 respectively.
It is placed on the support frames 3 and 4 so as to be located between 5 and the covers 86 and 87. Further, the above-described support frames 1 to 4
Include drive wheels DW1, DW2 and driven wheels FW1, FW2
In order to facilitate the riding operation of the vehicle, the rectangular plate-shaped flaps 91 to 96 are supported in a cantilever manner so as to freely swing, and each free end is resiliently supported at a position close to the road surface without coming into contact with the road surface. . This support structure will be described later with reference to FIG.

The operation when the front-wheel drive vehicle (not shown) is parked at a predetermined position by using the mobile parking apparatus of the present embodiment having the above-described structure will be described.
1 and DW2 ride on the supporting frames 1 and 2, respectively.
The vehicle is operated so that the driven wheels FW1 and FW2 ride on the support frames 3 and 4, respectively. Next, the lock mechanism 70
Is operated so that the hook portion 72 is not engaged with the spur gear 52, and the drive wheels DW1 and DW2 are
, The driving wheel DW2 does not rotate due to frictional engagement with the rods 11 and 21 of the support frame 2, but the first and second driving frames DW2 of the support frame 1 are rotated according to the rotation of the driving wheel DW1. The rollers 10, 20 rotate as follows.

That is, when the driving wheel DW1 rotates clockwise as indicated by the arrow Ra in FIG. 2, the first and second rollers 10, 20 are driven to rotate by frictional force, and the spur gear 51 rotates counterclockwise. While rotating, the spur gear 52 rotates counterclockwise. At this time, the spur gear 32 is replaced by spur gears 52 and 53.
And with the rotation of the spur gear 52, the spur gear 53
The rotational force of the spur gear 52 is transmitted to the spur gear 53, and the spur gear 53 also rotates counterclockwise. This rotational force is applied to the bevel gears 54, 5 shown in FIGS.
5 to the wheels 61, 62, and the wheels 61, 62
Rotates. On the other hand, a force acts on the spur gear 31 in a direction separating from the stopped spur gear 53 with the rotation of the spur gear 51 in the counterclockwise direction. It is in mesh with the spur gears 51 and 53. For this reason, the spur gear 31 also rotates together with the spur gear 51 and the spur gear 53 in a state where the rotation of the spur gear 51 is balanced, but does not transmit the rotational force of the spur gear 51 to the spur gear 53, and the first roller 10 It is substantially idle.

If the movement of the support frame 1 is prevented by an obstacle or the like while the drive wheel DW1 is rotating, the wheel 6
As the gears 1 and 62 decelerate and stop, the spur gear 53 decelerates,
It stops, and the spur gear 52 also decelerates and stops. For this reason, the second roller 20 is in the same state as when it is locked and cannot rotate, so that the driving wheel DW1 that continues to rotate kicks the second roller 20 and moves in the traveling direction of the vehicle, that is, to the right in FIG. , The first roller being almost entirely placed on the first roller 10.
Roller 10 is driven to rotate counterclockwise.
However, due to the relationship between the spur gear 51 in a rotating state and the spur gear 53 in a reduced or stopped state as the first roller 10 rotates, the spur gear 31 moves in a direction away from the spur gear 53. 31 is disengaged from the spur gear 53, and the first roller 10 and the spur gear 51 idle. Thus, since the first roller 10 idles, the drive wheel DW
1 does not move over the first roller 10 in the traveling direction.

When the braking device of the automobile is operated to stop the rotation of the drive wheel DW1, a rotational force is applied to the wheels 61 and 62 by the inertia force applied to the support frame 1 in a direction in which the wheels 61 and 62 continue to rotate. While the rotational force is transmitted to the spur gear 53, the spur gear 51 (and 52) is in a state of stopping from deceleration to stop, and the relationship between the two gears is opposite to that at the time of driving, similar to the so-called engine brake. State. That is, the inertial force of the support frame 1 is transmitted from the wheels 61 and 62 to the first roller 10 via the spur gear 53, the spur gear 31, and the spur gear 51, but the first roller 10 is driven by the braking force of the vehicle. Since the rotation is prevented, the support frame 1 eventually stops. Spur gear 5 at this time
Since the spur gear 51 is in the stopped state, the rotational force of the spur gear 53 in the counterclockwise direction is
1 works in the direction meshing with the spur gear 53 and the spur gear 51.

As described above, when the movement of the support frame 1 is prevented and the wheels 61 and 62 decelerate and stop, the drive wheels DW
When the first roller 10 is driven to rotate, the first roller 10 on the traveling direction side of the vehicle idles. On the other hand, the wheels 61 and 6
When the driving wheel DW1 is decelerated and stopped while the wheel 2 is rotating,
The braking force applied to the first roller 10 is transmitted as a negative rotation force to the wheels 61 and 62 that continue to rotate due to inertia, and stops the support frame 1. At this time, the rotation is also transmitted to the spur gear 52 on the second roller 20 side, but is substantially in the idling state. Thus, the mobile parking device moves in the direction indicated by the outline arrow Pa (in the direction perpendicular to the traveling direction of the vehicle) of FIG. 1 with the vehicle mounted thereon, and operates the braking device of the vehicle to rotate the drive wheel DW1. Can be stopped at a predetermined position in a stable state.

Since the other drive wheel DW2 is generally connected to the drive wheel DW1 via a differential gear (not shown), the drive wheel DW1 is driven when both of the drive wheels DW1 and DW2 are rotationally driven. When the wheel DW2 idles, the load on the drive wheel DW1 linked to the wheels 61 and 62 becomes larger than that on the drive wheel DW2, and the support frame 1 cannot be moved by the drive wheel DW1. Therefore, as described above, the drive wheels DW2 are supported by the rods 11 and 21 fixed to the support frame 2 so as not to run idle. Therefore, when the mobile parking device is driven by both drive wheels DW1 and DW2, the support frame 2 may be provided with the same mechanism as the drive wheel DW1.

When the vehicle is returned from the parking position to the original position, the driving wheel DW1 is rotated in the direction opposite to the above-described movement, and the vehicle moves in the direction of the outline arrow Pb in FIG. In any case, if the braking device of the automobile is operated, the drive wheel DW1
As the rotation of the vehicle stops and the mobile parking device also stops,
The lateral movement of the mobile parking device can be controlled by the same operation as the driving operation when the vehicle is moving forward and backward. When the vehicle escapes from the support frames 1 to 4,
If the operating lever 71 of the lock mechanism 70 is operated to engage the tip of the hook 72 with the spur gear 52, the second roller 20 is locked, so that the drive wheels DW1 and DW2 are driven to rotate. Thus, the vehicle can escape in the direction opposite to the approach direction.

As described above, in the mobile parking device of this embodiment, when the driving wheel DW1 rotates clockwise in FIG. 2 (the direction of the arrow Ra), the rotational force of the driving wheel DW1 becomes the second.
Is transmitted to the wheels 61 and 62 via the second roller 20, whereas the first roller 10 idles. Conversely, drive wheel DW
When 1 rotates in the counterclockwise direction in FIG. 2, the rotational force is transmitted to the wheels 61 and 62 via the first roller 10, but the second roller 20 idles. That is, for example, when the vehicle rotates the drive wheel DW1 in a direction that advances backward in the opposite direction to the above, the rotational force is transmitted to the roller on the front side, and the other roller (in the forward direction of the vehicle behind) Side) idles. Therefore, even if the drive wheel DW1 is rotationally driven in a state where the movement of the support frame 1 is blocked, the roller located on the traveling direction side of the vehicle idles, so that the drive wheel DW1 separates from the support frame 1. There is no danger that the car will jump in the direction of travel.

Further, the roller to which the rotational force is to be transmitted is automatically selected according to the rotational direction of the drive wheel DW1, and is supported by the arm members 35 and 36 when the main gear 53 is substantially stopped. The spur gears 51 and 52 on the traveling direction side of the vehicle according to the swinging motion of the spur gears 31 and 32.
Is disengaged from the spur gear 53, so that there is no danger of jumping out due to erroneous operation of the automobile. Also,
Since the support frames 1 to 4 and the connecting members 5 to 7 are detachable, they can be separated and stored, and assembled when necessary. Therefore, the mobile parking device having the above-described configuration can be mounted on an automobile, and can be appropriately removed and assembled when necessary.

FIGS. 15 and 16 show a front-wheel drive vehicle moving forward with respect to the mobile parking device. FIG. 17 relates to the case where the rear-wheel drive vehicle is moved forward with respect to the mobile parking device and placed. The drive mechanism in these embodiments has substantially the same configuration as the drive mechanism in the member 1xa in the embodiment of FIGS. 8 to 10, for example. However, in the embodiments of FIGS. Shaft 60 is connected to the connecting shaft 8, and the connecting shaft 8

Due to the rotation of the wheel 61, the vehicle supported by the wheels 61, 106, 107 and the support shaft 101 turns in the direction of the arrow Pc, and stops at the parking position indicated by the solid line in FIG. Therefore, the vehicle can be easily accommodated even in a parking space having a narrow frontage as shown by a two-dot chain line.
