Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile parking system for an automobile, and more particularly, to a drive wheel of a vehicle which is driven independently of the operation of a steering system of the automobile so that the vehicle can move at right angles to the traveling direction of the automobile. The present invention relates to a mobile parking device that can be moved laterally and parked at a predetermined position.

[0002]

2. Description of the Related Art Recently, various parking devices have been proposed and put into use so that an automobile can be parked in a limited space. For example, a three-dimensional parking device for vertically moving an automobile in order to expand a parking space is used, and this requires not only an elevating means but also a means for horizontally moving or rotating the automobile, which is relatively large. It becomes a device. On the other hand, various parking devices have been proposed in which horizontal movement or rotation is performed without moving up and down. As a parking device that moves in the horizontal direction, the wheels of the automobile are placed on a trolley, etc., and it is possible to move in the lateral direction at right angles to the traveling direction of the automobile without steering the automobile. It has been proposed that the vehicle can be parked in a parking lot having a slightly longer than the length.

For example, in Japanese Utility Model Publication No. 48-10183,
It is equipped with a pair of rollers that engage with the drive wheels of the automobile, and one of the rollers is driven to rotate by the drive wheels, and the drive force is transmitted to the wheels provided on the trolley so that it is substantially perpendicular to the traveling direction of the automobile. There have been proposed trolleys for moving vehicles that are designed to travel in the direction. Further, Japanese Utility Model Laid-Open No. Sho 53-70587 has a transmission mechanism for transmitting the rotational force of the roller to at least one of the trucks and a roller stopper device for fixing the roller, and the rotational force of the drive wheels of the automobile mounted on the truck. Proposes a moving device for an automobile in which the wheels of the truck are rotated via rollers and a transmission mechanism. The publication is provided with a transmission mechanism for transmitting the rotational force of one roller to the other roller, and both rollers are configured to be rotationally driven by the drive wheels of the automobile. Furthermore,
Japanese Utility Model Unexamined Publication No. 52-86188 discloses an automobile storage trolley having a pair of rollers provided on an underframe, in which a traverse wheel is rotationally driven by drive wheels of the automobile through a power transmission mechanism. The driving force is transmitted from the two rollers to the traverse wheel.

[0004]

In each of the mobile parking apparatuses disclosed in the above publications, in order to transmit the driving force of the drive wheels of the automobile to the wheels of the carriage, both have a roller and a power transmission mechanism and a part of them is provided. With the exception of the conventional device, a mechanism is provided for stopping the rotation of the rollers or the wheels of the carriage after moving to a predetermined position so as to be able to escape from the carriage.

However, in any of the mobile parking devices disclosed in the above publications, the wheels of the carriage are stopped by stopping the movement of the carriage, for example, when the movement of the carriage is blocked by an obstacle hitting the carriage or its wheels. If the roller connected to this locks, the drive wheel of the automobile may get over the roller and come off the truck. To deal with this, it is necessary to adjust the driving force of the car according to the locked state of the roller, but it is difficult to adjust the driving force at this time,
The moving operation requires skill, and the driving wheel may come off the trolley due to an erroneous operation.

[0006] In order to prevent this, the actual development of Sho 52-861
In No. 88 and No. 53-70587, a car stop is arranged on the driven wheel side of the automobile, but the desorption work is complicated. Moreover, if the driving force by the driving wheels becomes large, the car stop may be overcome, and in that case, the car will come off the bogie at a considerable speed. Furthermore, the actual development 4
Japanese Patent Laid-Open No. 8-10183 discloses an embodiment in which a shaft pin is provided on the driven wheel side of an automobile, and the shaft pin is rotated about the shaft pin. When the movement of the dolly is blocked by hitting an obstacle, the driving wheels of the automobile may come off the dolly, and it is difficult to put it into practical use.

Therefore, the applicant of the present application filed Japanese Patent Application No. 5-321.
No. 396, a support rotatably supporting a wheel and mounting at least one drive wheel of an automobile, and a support rotatably supported on the support at a predetermined distance in parallel with each other. A first roller and a second roller that are frictionally engaged with each other, and a first roller that restricts the rotation of the first roller in one direction so that a rotational force is transmitted when the first roller rotates in the forward direction and idles when rotating in the reverse direction. A one-way rotation restricting means, and a second one-direction rotation restricting means for restricting the rotation of the second roller in one direction so that the rotational force is transmitted when the second roller rotates in the reverse direction and the engine rotates idly when rotating in the normal direction. A rotation transmission mechanism that transmits the rotational force of the first and second rollers to the wheels via the first and second one-way rotation restricting means, and at least one of the first and second rollers. And a stop means capable of stopping the rotation of one of Regardless of the direction, it has proposed a mobile parking apparatus that can move in a predetermined direction the support table while supporting in a stable state in which the drive wheel on the roller.

According to this moving parking apparatus, the support base can be stopped by the braking operation of the automobile, and the vehicle can be parked at a desired position reliably based on the driver's intention. However, since the required height of the rotation restriction means and the rotation transmission mechanism is relatively high, there is no problem when parking a car with a high ground clearance, but when parking a car with a low ground clearance. In this case, the box accommodating the rotation restricting means and the like becomes an obstacle, and it is necessary to avoid this and drive the vehicle to stop at a predetermined position, which requires skill in driving.

Further, in the above-described mobile parking apparatus, the relationship between the rotational driving direction of the drive wheels of the automobile and the moving direction of the support base of the mobile parking apparatus is a relationship preset by a combination of gears and the like. If the relationship is reversed, a major design change is required. If the mobile parking device is set to move to the right when the drive wheels are rotated in the forward direction of the car, for example, change the support to move to the left when driving forward. In order to do so, the mechanism must be changed significantly. However, the relationship between the rotational driving direction of the drive wheels and the moving direction of the support base differs depending on the position of the parking area and the driving habit of the driver. For this reason, it is necessary to prepare at least two types of mobile parking devices in advance, but this causes a cost increase, so it is desirable to be able to appropriately change the relationship between the two.

Further, when only the driving wheels are driven, no problem occurs when the road surface is flat, but when the road surface on which the mobile parking device is arranged is inclined, the movement locus is Since it shifts in the direction of inclination, it is necessary to take some measures. As a measure against this, the above-mentioned actual exploitation 48
As described in Japanese Laid-Open Patent Publication No. -10183, it is conceivable that the wheels on the driven wheel side as well as the wheels on the driven wheel side are driven to rotate. Fixing is wasteful and not appropriate.
Further, in any of the devices described in any of the publications, the shafts that connect the wheels on the driving wheel side and the wheels on the driven wheel side are arranged at the left and right side end portions of the automobile, so that all wheels are supported by one platform. There is no choice but to adopt a format that makes it large and difficult to carry.

Therefore, according to the present invention, in the above movable parking apparatus, the height of the entire apparatus is kept low, the drive wheel can be moved in a predetermined direction while supporting the drive wheel on the roller in a stable state, and the drive wheel can be moved. It is an object of the present invention to provide a mobile parking device that can easily change the relationship between the rotational driving direction of the vehicle and the moving direction of the support base.

Further, according to the present invention, the height of the entire apparatus can be suppressed to a low level, the drive wheels can be supported on the rollers in a stable state, and the vehicle can be swiveled around one support shaft, and the drive wheels can be rotated. An object of the present invention is to provide a mobile parking device that can easily change the relationship between the driving direction and the turning direction of an automobile.

Further, another object of the present invention is that, in the above mobile parking apparatus, the support base can be moved in a predetermined direction while supporting the drive wheels on the rollers in a stable state, and the drive wheels can be synchronized with the wheels on the drive wheel side. Then, the mechanism for rotationally driving the wheels on the driven wheel side has a simple structure and can be appropriately mounted as needed.

Further, in the mobile parking apparatus, the vehicle is supported so as to be able to turn about one support shaft, and the vehicle is driven to turn in response to the rotation of the first and second rollers. can do.

Further, in the mobile parking apparatus, the drive wheels and the driven wheels other than the drive wheels of the automobile are movably supported by a plurality of wheels in accordance with the movement of the support base, and either the left or right side of the automobile is supported. On one side, a driven wheel-side wheel provided in the vicinity of the driven wheel disposed on the same side as the drive wheel is connected so as to rotate in synchronization with the rotation of the driven wheel-side wheel. The connecting mechanism may be detachably attached to the wheels on the drive wheel side and the driven wheel side.

The connecting mechanism includes a first shaft connected to the drive wheel side wheel, a second shaft connected to the driven wheel side wheel, the second shaft and the first shaft. Third fitting one end of each into the opening of both ends

It can be configured to transmit to two shafts.

[0019]

The operation of the mobile parking apparatus having the above structure will be described with reference to FIG.
It rides on T and is placed on the first and second rollers A1 and A2. At this time, for example, the second roller A2 is arranged so as to be located on the rear side of the automobile. In this state, when the rotation preventing state of the first roller A1 or the second roller A2 by the lock mechanism RM is released, and then the drive wheel DW1 is rotationally driven, for example, in the direction in which the automobile moves backward (Rb direction in FIG. 1). , The first and second rollers A1 and A2 are both driven in the directions opposite to the rotation direction of the drive wheel DW1 (Db and Fb directions in FIG. 1, respectively). At this time, the first and second rollers A1 and A2 are rotated. The rotation directions of A1 and A2 are assumed to be forward rotation.
That is, when the second roller A2 is located on the rear side of the vehicle and both the first and second rollers A1 and A2 are driven in the normal direction, the first one-way clutch mechanism B1 causes the first roller to move. The rotational force of A1 is transmitted to the first bevel gear G1 and further transmitted to the wheels RW of the support base MT via the rotation transmission mechanism CT including the third bevel gear G3, while the second roller A2 is used. Is idled by the second one-way clutch mechanism B2 (indicated by a broken line arrow Fb in FIG. 1), and the rotational force is not transmitted.

On the contrary, the direction in which the car is moving forward (R in FIG. 1)
When the drive wheel DW1 is rotationally driven in the (a direction), both the first and second rollers A1 and A2 are reversely driven (Fa and Da directions in FIG. 1, respectively). In this case, the first roller is driven. A1 idles by the first one-way clutch mechanism B1, the rotational force of the second roller A2 is transmitted to the second bevel gear G2 by the second one-way clutch mechanism B2, and further the fourth bevel gear G4 is turned on. It is transmitted to the wheels RW of the support base MT via the rotation transmission mechanism CT including the same. Accordingly, when the movement of the support base MT is prevented during both forward rotation and reverse rotation of the first and second rollers A1 and A2, the first vehicle positioned on the forward or rearward traveling direction side of the vehicle. Roller A
Since the first or second roller A2 is in the positional relationship of idling, the drive wheel DW1 does not come off from the support base MT.

When the drive wheel DW1 is to be removed from the support base MT, the rotation of the first roller A1 or the second roller A2 (the second roller A2 in FIG. 1) located in the direction of escape is locked by the lock mechanism RM. Drive wheel DW1 after being blocked by
1 is rotationally driven in the Rb direction, a driving force is applied to the support base MT that is stopped at a predetermined position in a direction in which the support base MT escapes. Therefore, the drive wheel DW1 can be easily removed from the support base MT. You can The other drive wheels and driven wheels of the automobile are mounted on, for example, another support base that rotatably supports the wheels, but one support base that exposes the first and second rollers A1 and A2. It is also possible to mount all the wheels of the vehicle on the vehicle and support the vehicle so that the vehicle can be moved according to the movement of the support base by the rotational driving of the drive wheel DW1.

Then, by rotating the driving wheels DW1 of the automobile, the first roller A1 or the second roller A1.
The rotational force of 2 is transmitted to the wheels RW of the support base MT on which the drive wheels DW1 are mounted, and the wheels RW are rotationally driven to move the vehicle in a predetermined direction, for example, a direction perpendicular to the traveling direction of the vehicle. As described above, the first and second rollers A
1, A2 and the wheels RW are the first and second bevel gears G1,
Since G2 and the rotation transmission mechanism CT including the third and fourth bevel gears G3 and G4 are connected to each other, the height of the entire device is larger than the diameter of the first and second rollers A1 and A2. The height of the wheels RW may be a minimum height for grounding, and the height may be low. Therefore, even an automobile having a low minimum ground clearance can be operated without any trouble.

The vehicle can be set to move in any direction by appropriately changing the predetermined angles of the axes of the first and second rollers A1 and A2 with respect to the rotation axis of the wheel RW. When changing the relationship between the rotational driving direction of the drive wheel DW1 and the moving direction of the support base MT, the first and second bevel gears G1 and G2 of the third and fourth bevel gears G3 and G4 are changed. The meshing relationship with respect to may be reversed. For example, if the third and fourth bevel gears G3 and G4 are fixed to both ends of the shaft and are detachably supported on the support base MT, the fourth bevel gear G4 becomes the first bevel gear G1. Since the third bevel gear G3 and the third bevel gear G3 can be arranged so as to mesh with each other and mesh with the second bevel gear G2, the meshing relationship can be easily changed as necessary.

In the moving parking apparatus in which the vehicle is supported so as to be able to turn about one support shaft, the drive wheel DW1 is supported in a stable state on the first and second rollers A1 and A2 as described above. At the same time, in response to the rotation of the first and second rollers A1 and A2 due to the rotational driving of the drive wheel DW1, the automobile makes a turning motion around the support shaft and stops at a predetermined stop position. Even in this case, since the height of the entire apparatus can be suppressed to a low level, it is possible to operate a vehicle having a low minimum ground clearance without any trouble. Further, the relationship between the rotational driving direction of the drive wheel DW1 and the turning direction of the automobile is easy if the meshing relationship between the third and fourth bevel gears with respect to the first and second bevel gears is reversed as described above. Can be changed to

Further, in the mobile parking apparatus provided with the connecting mechanism for rotating the driven wheels in synchronism with the driving wheels, the wheels on the same side as the driving wheels and the driven wheels are also rotationally driven through the connecting mechanism. Therefore, it can be moved in a predetermined direction even on an inclined road surface.

The locking mechanism 70 of this embodiment is provided with the flap 7
The lock plate 71 is provided integrally with a, and the hook portion 72 formed at the tip of the lock plate 71 is configured to engage with and disengage from the groove 20a on the surface of the second roller 20.
Further, as shown in FIG. 8, a joint plate 84 is fixed to the side surface of the frame member 1c with bolts (not shown). This joint plate 84 is a long plate body as shown in FIG. 10, notches 84c are formed, and support plates 83 are fixed to both sides by welding or the like, and the surface of the joint plate 84 as shown in FIG. To the vertical direction.

The support plate 74 is supported by the joint plate 84 by the bolt 81 via the spring 82 so as to overlap with the joint plate 84. still,
The support plate 74 may be directly supported on the side surface of the frame member 1c. The support plate 74 is an elongated plate body, and as shown in FIG. 11, a pair of elongated holes 74b and a cutout portion 74c are formed, and the above bolt 81 is inserted into the elongated hole 74b, and the support plate 74 is inserted through the cutout portion 74c. The support plate 83 extends and a bolt (not shown) is provided. That is, the support plate 74 is connected to the joint plate 84 by the spring 8
It is pressed and supported by the joining plate 84 by the elastic force of 2, and is supported by the elongated hole 74b so as to be movable in the vertical direction.

The drive plate 73 is fixed to the support plate 74 by welding or the like so as to extend in a direction perpendicular to the surface of the support plate 74. A lock plate 71 is fixed to the opposite surface by welding or the like so as to extend in the vertical direction. The support plate 74 is
As shown in FIG. 13, at the longitudinal side end located above,
An inclined plate 75 is fixed at a predetermined angle by welding or the like, and a flap 7a is configured with a plate 76 joined to its free end and a plate 77 joined laterally.

On the other hand, a shaft 85 is rotatably supported in the hole 83c of the support plate 83 shown in FIG. 12 as shown in FIGS. 8 and 9, and a lever 86 is fixed to the shaft 85 by welding or the like. There is. As shown in FIG. 13, a hole 86a is formed at the tip of the lever 86, and a pin or bolt (not shown) screwed into the hole 86a is fitted in a notch 73a formed in the drive plate 73. It is arranged to. Further, the pedal 8 is attached to one end of the shaft 85.
8 is cantilevered, and the lever 86 is configured to rotate in the counterclockwise direction in FIGS. 8 and 13 by pushing down the tip portion thereof.

As shown in FIG. 8, the flap 7a is normally held by the elastic force of the spring 82 so that the tip portion has a predetermined gap with the road surface. When the drive wheel DW1 of the automobile rides on the flap 7a, the flap 7a swings around the lower end of the support plate 74 as a fulcrum against the elastic force of the spring 82, and stops when the tip end contacts the road surface. . In this case, the lock mechanism 7
If the hook portion 72 of 0 and the groove 20a on the surface of the second roller 20 are in the engaged state, the support plate 74 side moves downward due to the load applied on the inclined plate 75, and the lock plate 71 accordingly. Moves downward and is disengaged. Accordingly, when the drive wheel DW1 is placed on the first and second rollers 10 and 20, the lock mechanism 70 is provided.
Is in the released state unless the pedal 88 is operated
The rotation of the second rollers 10 and 20 is not hindered.

When the drive wheel DW1 is to be removed from the support frame 1, the lever 8 can be pushed down by pushing down the tip of the pedal 88.
6 rotates in the counterclockwise direction in FIG. 8, the drive plate 73 and the lock plate 71 are driven upward by a pin or the like (not shown), and the hook portion 72 causes the groove 2 on the surface of the second roller 20.
0a and the rotation of the second roller 20 is blocked.
Therefore, if the drive wheel DW1 is rotationally driven in the direction opposite to that when the drive wheel DW1 enters the support frame body 1, the drive wheel DW1 will escape from the support frame body 1. At this time, the drive wheel DW1 is moved to the flap 7
Since the vehicle rides on a, the flap 7a moves downward, and the engagement between the hook portion 72 of the lock mechanism 70 and the groove 20a of the second roller 20 is automatically released. in this way,
The lock mechanism 70 is driven by the operation of the pedal 88, and the rotation blocking state with respect to the second roller 20 is automatically released by the downward movement of the flap 7a. You can move to the parking area.

The pedal 88 is provided with an extending portion extending from the shaft 85 to the side opposite to the pressing portion, and a wire (not shown) formed of, for example, a piano wire is erected on the extending portion. The grip may be provided at the tip. With such a configuration, the driver can drive the lock mechanism 70 by simply pulling up the grip portion from the window while riding in the automobile, so that better operability can be obtained.
Moreover, since the wire is flexible, there is no risk of damaging it even if it comes into contact with the automobile during movement.

The operation when the front wheel drive vehicle (not shown) is parked at a predetermined position using the moving parking apparatus of the present embodiment having the above-mentioned structure will be described. The front drive wheel DW in FIG.
1 and DW2 ride on the support 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. At this time, drive wheel DW
Since 1 rides on the flap 7a, even if the flap 7a is in the upper position, the lock mechanism 70 shown in FIG.
Of the lock plate 71 moves downward together with the support plate 74, and the engagement between the hook portion 72 and the second roller 20 is automatically released. When the drive wheels DW1 and DW2 are rotationally driven in this state, the drive wheels DW2 are driven by the rod 10 of the support frame 2.
Drive wheel D does not rotate due to frictional engagement with r, 20r
The first and second rollers 1 of the support frame 1 according to the rotation of W1
0 and 20 rotate as follows.

For example, when the drive wheel DW1 is rotationally driven in the direction in which the vehicle is moved forward as it is, that is, when the drive wheel DW1 is rotationally driven clockwise as viewed from the bottom of FIGS. 3 and 4, the first and second driving wheels DW1 are driven. The rollers 10 and 20 are rotationally driven by frictional force, the shaft 11 rotates counterclockwise, and the shaft 21 rotates counterclockwise. At this time,
The shaft 21 is engaged with the bevel gear 42 via the second one-way clutch mechanism 32, and the rotating force of the shaft 21 causes the bevel gear 4 to rotate.
It is transmitted to 2 and rotates counterclockwise. This torque is
It is transmitted to the wheels 61 and 62 via the bevel gear 52 and the spur gears 53 to 56 shown in FIG. 4, and the wheels 61 and 62 rotate. On the other hand, on the first roller 10 side, the engagement between the outer cylindrical body 31a and the inner cylindrical body 31b of the first one-way clutch mechanism 31 is released, and the first roller 10 is in the idling state.

Then, for example, when the movement of the support frame 1 is blocked by an obstacle or the like while the drive wheel DW1 is rotating,
As the wheels 61 and 62 decelerate and stop, the first and second bevel gears 41 and 42 also decelerate and stop. Therefore, while the second roller 20 cannot rotate, the drive wheel DW1
Since it continues to rotate, it kicks the second roller 20 to move in the traveling direction of the vehicle, that is, to the right in FIG. 4, and rides on only the first roller 10. However, with the counterclockwise rotation of the first roller 10 at this time, the shaft 11 that is in a rotating state and the bevel gear 4 that is in a decelerating or stopped state.
Due to the relationship with 1, the outer cylinder body 31a and the inner cylinder body 31b in the first one-way clutch mechanism 31 do not engage with each other, and thus the first roller 10 idles. in this way,
Since the first roller 10 on the traveling direction side idles, the drive wheel DW1 does not ride over the first roller 10 and jump out in the traveling direction.

When the braking device of the automobile is operated to stop the rotation of the drive wheel DW1, the inertial force applied to the support frame 1 gives a rotational force to the wheels 61 and 62 in a direction in which the wheels continue to rotate. While the rotational force is transmitted to the bevel gears 41 and 42, the shafts 11 and 21 are in a state of deceleration to stop, and the relationship between the two is opposite to the above-described driving time. That is, the inertial force of the support frame 1 is the wheel 6
1, 62 to spur gears 56, 55, 54, 53, bevel gears 5
1, 52 are transmitted to the bevel gears 41, 42, but the rotation of the first and second rollers 10, 20 is blocked by the braking force of the vehicle. Therefore, the first and second one-way clutch mechanisms 31 , 32, the relationship between the relative velocities of the outer cylinder and the inner cylinder is reversed. Therefore, while the second roller 20 is in the idling state, the braking force applied to the first roller 10 is transmitted to the wheels 61 and 62 as a negative rotational force, and finally the support frame 1 is It will be stopped.

As described above, when the movement of the support frame 1 is blocked and the wheels 61 and 62 decelerate and stop, the drive wheels DW.
When 1 is rotationally driven, the first roller 10 on the traveling direction side of the vehicle runs idle. On the other hand, the wheels 61, 6
When decelerating and stopping the drive wheel DW1 while 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 the support frame 1 is stopped. Then, the mobile parking device moves in the direction of the white arrow Pa (the direction perpendicular to the traveling direction of the vehicle) in FIG. 2 with the vehicle mounted, and operates the vehicle braking device to rotate the drive wheel DW1. By stopping, it is possible to stop at a predetermined position in a stable state.

Since the drive wheel DW2 on the other side is generally connected to the drive wheel DW1 via a differential gear (not shown), it is driven when both the drive wheels DW1 and DW2 are rotationally driven. When the wheel DW2 idles, the load on the drive wheel DW1 side interlocking with the wheels 61 and 62 becomes larger than that on the drive wheel DW2 side, and the support frame 1 cannot be moved by the drive wheel DW1. Therefore, as described above, the rods 10r, 20 fixed to the support frame 2 are prevented so that the drive wheels DW2 do not idle.
It is supported by r. Therefore, both drive wheels DW1, DW2
When the mobile parking device is configured to be driven by, the support frame 2 may be provided with the same mechanism as the drive wheel DW1 side.

When the vehicle is returned from the parking area to the original position, if the drive wheel DW1 is rotationally driven in the opposite direction to the above-mentioned movement, the vehicle moves in the direction of the outline arrow Pb in FIG. In either case, if the vehicle braking device is operated, the drive wheel DW1
Since the rotation of the car 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 moves forward and backward.

When the vehicle is to be removed from the support frames 1 to 4, the pedal 88 is operated to drive the lock plate 71 of the lock mechanism 70, and the tip of the hook portion 72 is attached to the second roller 20. The second roller 20 is locked when it is engaged with the groove 20a on the front surface. Therefore, by rotating the drive wheels DW1 and DW2 in the opposite direction, the vehicle is moved in the direction of approach to the support frames 1 to 4. You can escape in the opposite direction.

As described above, in the mobile parking apparatus of this embodiment, when the drive wheel DW1 rotates clockwise as viewed from the bottom of FIGS. 3 and 4, the rotational force of the drive wheel DW1 is the second roller. While being transmitted to the wheels 61 and 62 via 20, the first roller 10 runs idle. Conversely, drive wheel D
When W1 rotates counterclockwise as viewed from below in FIGS. 3 and 4, the rotational force is transmitted to the wheels 61 and 62 via the first roller 10, but the second roller 20 idles. To do. That is, drive wheel DW1
When is driven to rotate, the rotational force is transmitted to the roller on the front side, and the other roller (which is on the backward traveling direction side of the automobile) runs idle.

Therefore, even if the drive wheel DW1 is rotationally driven in a state in which 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 DW is driven.
1 does not separate from the support frame 1, and there is no risk of the automobile jumping out in the traveling direction. That is, the roller to which the rotational force is transmitted is the first and second one-way clutch mechanism 3
1, 32 the direction of rotation of the drive wheel DW1 and the wheel 6
Since the shaft 11 or 21 of the first or second roller 10 or 20, which is the traveling direction side of the automobile, idles, it is automatically selected in accordance with the relative speed with respect to 1, 62.
There is no risk of popping out due to incorrect operation of the car.

When the relationship between the rotational driving direction of the drive wheel DW1 and the moving direction of the support frame 1 is set to the opposite relationship to the above-mentioned embodiment, the bevel gears 51 and 52 and the spur gear of FIG. 4 are set. 5
3, the sub-assembly consisting of the shaft 57 and the bearing is removed, and as shown in FIG. 15, it is sufficient to perform a simple operation of arranging the sub-assembly of FIG. Therefore, the driver can appropriately set or change the moving direction according to the position of the parking area.
Furthermore, if the support frames 1 to 4 and the connecting mechanism 9 are made detachable, they can be stored separately and assembled when necessary. Therefore, it is also possible to mount the mobile parking device having the above-mentioned configuration on a vehicle and take it out and assemble it as needed.

As described above, the bevel gears 41, 42, 51, 52 and the spur gears 53 to 5 are used in the mobile parking apparatus of the above embodiment.
6, and first and second one-way clutch mechanisms 31, 32
The first and second rollers 1 as shown in FIG.
The minimum height required for the wheels 61 and 62 to contact the ground is added to the diameter of 0 and 20, and the overall height is kept low. Therefore, the mobile parking device does not interfere with a vehicle having a low minimum ground clearance.

The above embodiment is included in the configuration shown in FIG. 1. However, by combining various concrete means of each component of FIG. 1, it is possible to provide a mobile parking device of various aspects. it can. For example, the support base MT is not limited to the support frame body 1 of the present embodiment, but is a long plate body including the support frame body 3 for the driven wheel FW1, and the first and second rollers 10, 2 are provided.
The opening may be formed so that 0 is exposed. Further, all the support frame bodies including the support frame bodies 2 and 4 may be formed as a single plate body, and all the components may be mounted on the plate body.

Wheels RW that can be connected to the rotation transmission mechanism CT
In the above embodiment, two examples of the wheels 61 and 62 are shown, but the number may be one or three or more. Although the lock mechanism 70 of the above-described embodiment is configured to engage the hook portion 72 of the lock plate 71 with the groove 20a on the surface of the second roller 20,
A disc may be separately provided on the shaft of the second roller 20, and the hook 72 may be engaged with a groove formed in the outer peripheral end face of the disc to lock the disc. Further, the lock mechanism 70 may be configured to electrically drive using a solenoid. Further, as shown by a chain double-dashed line in FIG.
And blocks 1k and 2k for stoppers on the rod 10r side
May be provided.

In the above-described embodiment, the wheels 61 and the like provided on the support frames 1 to 4 all rotate about axes perpendicular to the rotation axes of the first and second rollers 10 and 20, The support frames 1 to 4 are configured to move in a lateral direction at right angles to the traveling direction of the automobile, but the wheels 61 and the like are rotated about an axis deviated by a predetermined angle with respect to the support frames 1 to 4. With this configuration, the vehicle can be moved in a direction oblique to the traveling direction.

FIGS. 16 to 18 show an embodiment of a movable parking apparatus in which an automobile is supported so as to be able to turn about a single support shaft, and FIGS. 16 and 17 show a front-wheel drive vehicle moving forward with respect to the movable parking apparatus. FIG. 18 relates to the case where the rear-wheel drive vehicle is moved forward and mounted with respect to the mobile parking device. The drive mechanism in these embodiments has substantially the same structure as the drive mechanism of the above-mentioned embodiments, but in the embodiments of FIGS. 16 and 17, the wheels 61 to 64 are not provided and the shaft 60 is the connecting mechanism. 9 is directly connected to a connecting shaft 94, and the connecting shaft 94 is connected to a wheel 103 described later. Further, the embodiment of FIG. 18 has only one wheel 62. In either embodiment,
The support portion 1s on the side of one drive wheel DW1 is
The supporting portions 2s for supporting the rods 10r, 20r on the W2 side are integrally formed by the common beams 1sb, 2sb, and the supporting portions 3 for the driven wheels FW1, FW2.
s and 4s are also integrally formed by the common beams 3sb and 4sb. The deck member D1 that constitutes the supporting portion 3s and is joined to the supporting portion 1s, and the supporting portion 4
The deck member D that constitutes s and is joined to the support portion 2s.
2 are installed side by side.

In the embodiment shown in FIGS. 16 and 17, the wheel 103 is rotatably supported between the beams 3sb and 4sb on the driven wheel side, and the shaft 96 of its rotating shaft is connected to the connecting shaft 94. . A support bracket 100 is attached to the beam 1sb on the front side of the vehicle, that is, on the drive wheel side.
Is fixed, and the support shaft 101 is attached to the support bracket 100.
Are configured to be fitted together. The support shaft 101
Is arranged so as to be located on the extension line of the shaft 60,
It is fixed to the road surface via the bracket 102. Support part 2
Wheels 104 and 105 are attached to s and 4s, respectively, and both are rotatably supported around an axis passing through the support shaft 101. Further, flaps 7d and 7f are attached to the support portions 3s and 4s, respectively. However, since the mechanism including the pedal 88 that constitutes the lock mechanism is separated from the flap 7d, and the engagement with the second roller 20 cannot be released in conjunction with this, the second roller is independently provided. 20
It must be configured so that the rotation of can be stopped or released.

On the other hand, in the embodiment shown in FIG. 18, the support bracket 100 is fixed to the beam 4sb on the driven wheel side, and the support shaft arranged on the extension line of the rotation axis of the wheel 62 is attached to the support bracket 100. 101 is configured to be fitted. Further, wheels 106 and 107 are mounted on the supporting portions 2s and 4s, respectively, and both are supporting shafts 1
It is rotatably supported around an axis passing through 01. Further, flaps 7a and 7b are attached to the supporting portions 1s and 2s, respectively.

Thus, for example, the movable parking apparatus of the embodiment shown in FIG. 18 is left in a state in which it is pivoted around the support shaft 101 as shown by the chain double-dashed line in FIG. The driven wheel in front of (1) is placed on the support portions 3s and 4s, and the drive wheel is placed on the support portions 1s and 2s. Then, when the drive wheel is rotationally driven, the first and second rollers 10 and 20 rotate, and the rotational driving force is transmitted to the wheel 62 of the support portion 1s. Due to the rotation of the wheels 62, the vehicle supported by the wheels 62, 106, 107 and the support shaft 101 turns in the direction of arrow Pc and stops at the stop position shown by the solid line in FIG. Therefore, the vehicle can be easily accommodated even in a parking space having a narrow frontage as indicated by a chain double-dashed line. Further, since the support shaft 101 is arranged on the extension line of the rotation shaft of each of the wheels 62, 106 and 107, the support shaft 101 is rotated according to the rotation of the wheels 62, 106 and 107 around the rotation shaft in different directions. The swivel motion is performed around the point of, and almost no force is applied to the support shaft 101 in the direction perpendicular to the support shaft 101 (that is, in the horizontal direction). Therefore, the bracket 102 can be fixed by a simple method such as bonding.

The movable parking apparatus shown in FIGS. 16 and 17 operates in the same manner as the apparatus shown in FIG. 18, but the embodiment shown in FIG. 16 is for a front-wheel drive vehicle, and the front drive wheels are near the support shaft 101. Since the first and second rollers 10 and 20 are mounted on the supporting portions 1s and 2s, the first and second rollers 10 and 20 are connected to the wheel 103 provided on the driven wheel side via the connecting shaft 94.
03 is rotationally driven. As described above, FIGS.
Also in the eighth embodiment, since the drive wheels are supported on the first and second rollers 10 and 20 in a stable state, the vehicle is surely turned around the support shaft 101 in accordance with the rotational drive of the drive wheels. Can be driven.

By the way, when the driver leaves the vehicle while the vehicle is placed on the moving parking device, the parking brake is operated, and in the case of an automatic transmission vehicle, the shift device is set to the parking position and then the vehicle is alighted. Is common. In particular, if the drive wheels are locked, such as when the shift position is set to the parking position, the stopped state is maintained even if the road surface on which the mobile parking device is installed is inclined, and the vehicle does not start moving due to its own weight. However, when getting off the vehicle without taking such measures on the sloped road, the mobile parking device on which the vehicle is mounted may start to move due to its own weight. Further, even if only the mobile parking device is used, it may start to move due to its own weight on an inclined road surface.

With regard to this, if a constant initial braking force is applied to the mobile parking apparatus of the above-described embodiment, assuming a case where the vehicle is parked on an inclined road surface, the mobile parking system does not start even if the vehicle is alighted. When the device is moved, it is sufficient to rotate the driving wheels with a driving force that exceeds the initial braking force, so that the above problem can be solved. However, in this case, even if only the movable parking device is used, it cannot be moved manually against the initial braking force. Therefore, the support frame 1 has to be lifted, which is not an easy task.

Therefore, at all times, an initial braking force is applied to the moving parking device so that the moving parking device does not start to move due to its own weight, and the driving force of the vehicle exceeding the initial braking force is applied so that the moving parking device is moved manually. In the case of making it possible, it may be configured to release the initial braking force. For example, in FIG.
As shown in FIGS. 0 and 21, a limiting mechanism 200 that can apply an initial braking force to the bevel gear 41 shown in FIGS. 3 to 5 is provided, and the limiting mechanism 200 can be intermittently operated by operating the pedal 201.

That is, in FIGS. 20 and 21, the shaft 202 is slidably supported between the frame member 1b constituting the support frame 1 and the support plate 1g, and the braking member 203 is provided at the intermediate portion of the shaft 202. It is provided. This braking member 2
03 has a substantially U-shape when viewed from the front and is arranged so as to surround the body portion of the bevel gear 41, and the body of the bevel gear 41 is provided on one of the inner surfaces facing each other (right side in FIGS. 20 and 21). A recessed portion 204 is formed which abuts the outer peripheral surface of the portion and constitutes a braking surface. One end of the shaft 202 is shown in FIG.
0 and the left side of FIG. 21, a holder 205 is fixed to the tip end, and a spring 206 that urges the holder 205 and the supporting plate 1g so as to expand the two is interposed. There is. That is, the shaft 202 is shown in FIGS.
Is biased in the direction of moving to the left of
04 is urged in the direction of coming into contact with the outer peripheral surface of the body portion of the bevel gear 41.

The other end of the shaft 202 extends outward from the frame member 1b, and the pedal 201 is rotatably supported at the tip of the frame 202. Between the pedal 201 and the frame member 1b, there are cam members 207, 2 having an inclined end surface.
No. 08 is interposed, and the inclined end faces are arranged so as to face each other and have a slight gap at the initial position. Then, one cam member 207 is fixed to the frame member 1b, and the other cam member 208 is fixed to the pedal 201.

Thus, the pedal 201 is shown in FIGS.
The cam member 20 is rotated clockwise when viewed from the right side of the.
8 is in contact with the end surface of the cam member 207,
08 rotates while sliding on the cam member 207.
As a result, the shaft 202 moves to the right in FIGS. 20 and 21 against the biasing force of the spring 206, and the outer peripheral surface of the body portion of the bevel gear 204 is disengaged from the concave portion 204, so that the initial braking force is reduced. Grant is canceled. On the other hand, the pedal 20
When 1 is rotated counterclockwise as viewed from the right side of FIGS. 20 and 21 and returned to the original position, the cam members 207 and 208 return to the states shown in FIGS.
The concave portion 204 abuts the outer peripheral surface of the body portion of the bevel gear 41 by the urging force of, and an initial braking force is applied. The limiting mechanism 2
The object to which the initial braking force is applied at 00 is not limited to the bevel gear 41, but the bevel gear 42 and the bevel gear 5 on the high speed side (low rotational force side)
1, the shaft 57 or the like may be used. Also, the pedal 201
However, other operating members may be used. Alternatively, a wire may be connected to the end of the shaft 202 so that the initial braking force is not applied while the wire is being pulled.

[0074]

Since the present invention is constructed as described above, it has the following effects. That is, the mobile parking apparatus of the present invention is configured such that the first roller, which is on the traveling direction side of the vehicle when the movement of the support base is blocked, in both the forward rotation and the reverse rotation of the first and second rollers, Since the second roller is configured to idle, the drive wheel can be stably supported on the first and second rollers regardless of the rotation direction of the drive wheel, and the movement of the support base can be prevented. However, the drive wheels will not be separated from the support base even if is blocked. Moreover, the bevel gear, the one-way clutch mechanism and the like keep the overall height of the device low, and the ground clearance is configured to be as small as possible. Without, it can be operated easily.

Thus, the present invention can be applied to various automobiles, and by merely placing the drive wheels on a support and driving them to rotate, the automobile can be driven in a predetermined direction, for example, a direction perpendicular to the traveling direction of the automobile. You can move to and park in place. Further, the relationship between the rotational driving direction of the drive wheels and the moving direction of the support base can be immediately changed by only changing the meshing relationship between the third and fourth bevel gears with respect to the first and second bevel gears. You can easily and quickly set the moving direction,
Alternatively, it can be changed.

Further, in the moving parking apparatus in which the vehicle is supported so as to be turnable around one support shaft, the drive wheels are first
Also, while being supported in a stable state on the second roller, the vehicle can be driven to rotate around the support shaft in accordance with the rotational drive of the drive wheels, and the height of the entire device is kept low. Therefore, even a vehicle with a low minimum ground clearance can be operated without any trouble. Further, the relationship between the rotational drive direction of the drive wheels and the turning direction of the automobile can be easily set or changed.

Further, in the mobile parking apparatus having the connecting mechanism for rotating the driven wheels in synchronism with the driving wheels, the wheels on the same side as the driving wheels and the driven wheels are also rotationally driven through the connecting mechanism. Therefore, it is possible to move in a predetermined direction even on an inclined road surface. Moreover, since the connecting mechanism is detachable, the connecting mechanism can be properly attached as needed.
