BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revolving type parking device for transferring a vehicle to a narrow parking space while holding the vehicle and parking the vehicle.

[0002]

2. Description of the Related Art In recent years, it has been demanded to minimize the occupation area of a parking space in a site area in order to make effective use of narrow land due to soaring land and the like. In such a case, it is indispensable to change the direction for parking, and it is necessary to secure an extra space for changing the direction in the parking space. For this reason, in a parking space having a narrow frontage with a small space for turning directions, not only is advanced driving technique such as a car approaching required, but also there is a surface that requires much time for parking such as turning the steering wheel many times.

For example, Japanese Patent Application Laid-Open No. 50-15272 discloses a bogie provided with a pair of wheels at the rear end of a rear surface as an apparatus for easily parking a vehicle in such a narrow parking space. A drive motor is installed at the center of the bogie while being rotatably supported on the support shaft, and a drive shaft of the drive motor is extended between the wheels, and is attached to the tip of the drive shaft and the center axis of one of the wheels. A vehicle storage device has been proposed in which a sprocket is fixed, an endless chain is stretched between these sprockets, and wheels are rotated by a drive motor, so that the bogie turns to the storage position with the vehicle mounted. ing. Further, Japanese Utility Model Laid-Open Publication No. 2-33969 discloses that a bogie having wheels is supported on a base member fixed to a parking space, a winch is supported on a support standing upright at one end of the base member, and the winch is wound around the winch. The width adjustment cart of the car which fixed the both ends of the attached wire rope to the back side of the base member via pulleys, and turned the winch by turning the handle of the winch manually to wind up the wire rope was used. Proposed.

[0004]

[Problems to be Solved by the Invention]
In the vehicle storage device proposed in Japanese Patent Publication No. 272, the vehicle can be easily put in and out even in a narrow parking space by turning the bogie by a predetermined angle.
When it is desired to increase the output of the drive motor for reasons such as installing a vehicle storage device on an inclined surface or mounting a relatively heavy vehicle having a large weight, the drive motor also increases in size. Since the drive motor is located at the center of the bogie, the drive motor structurally dives under the vehicle while the vehicle is on the bogie.If a large drive motor is used, the drive motor There is a risk of interference with the side. Further, since the wheels are directly driven through the chain by the rotation of the drive motor, a step is generated between the road side and the parking position, and when the drive wheel side is in a floating state, the driving force is not transmitted and the bogie cannot be turned. In addition, when the road surface is frozen, such as in a winter period, the wheels slip, and the rotation of the drive wheels cannot be transmitted to the road surface efficiently, and the truck cannot move smoothly.
In this regard, the width approaching trolley proposed in Japanese Utility Model Laid-Open Publication No. 2-33969 can directly turn the trolley regardless of the road surface condition because the trolley is directly driven by the wire rope. Since the winch that winds the vehicle is mounted on a column that stands outside the bogie, the winch serving as the driving means does not interfere with the vehicle that has been mounted on the bogie. However, this trolley is
It is a manual operation of the winch to wind up the wire rope, which requires labor to move the trolley, and is a heavy labor for powerless women and the elderly. Furthermore, since the winch is pivotally supported on a column standing outside the bogie, and a wire rope drawn vertically from the winch is hung on a pulley and fixed to the back side of the bogie, the column supporting the winch at the parking position is provided. In addition to the installation space, a wasteful space for routing the wire rope is required, and a narrow parking space cannot be used effectively. In addition, if the winch for moving the bogie is electrically driven, it is possible to reduce the labor required for moving the bogie. In this way, when the bogie is automatically moved, the bogie may be stopped at a predetermined position. It becomes a problem. That is, when the bogie is moved by the electric winch, in order to stop the bogie, it is necessary to manually stop the electric winch to drive the bogie when the bogie has moved to a predetermined stop position while checking the position of the bogie. There is a danger that the bogie will protrude greatly on the road side if the stop operation is wrong. For this reason, it is necessary to monitor the movement of the trolley from beginning to end, which is troublesome and troublesome. In particular, it is extremely troublesome to continuously monitor the trolley outdoors in bad weather such as wind and rain or snow.

[0005] The present invention is intended to solve such a problem, and it is possible to effectively use a narrow parking space and to automatically stop a parking pallet at a predetermined position. It is intended to provide a parking device.

[0006]

According to the present invention, in order to achieve the above object, a shaft portion is provided on an installation surface serving as a parking space, and a wheel rolling on the installation surface is provided on each of the corners on the back surface. A parking pallet provided in the parking pallet, a turning type parking device for turning the parking pallet and storing a vehicle riding on the parking pallet in a parking space, wherein a sprocket is provided on a side outer surface of the parking pallet; A drive motor for driving the sprocket by normal / reverse rotation by operation is fixed, a guide plate for fixing both ends of the chain is fixed on the installation surface, and a guide rail for guiding the chain is provided on the guide plate. The guide plate and the guide rail are arc-shaped around the shaft portion, and the chain is stretched along the trajectory of the sprocket by the guide plate and the guide rail, and One end of the guide plate protrudes from the parking pallet to fix one end of the chain to a position directly exposed to the outside, and the sprocket engages with one end of the chain protruding from the parking pallet, and the drive Detecting means for controlling the drive motor by detecting a turning angle of the parking pallet while rotating the parking pallet by the chain around the shaft portion by the rotation of the motor, and detecting a detection signal from the detecting means , The parking pallet is automatically stopped at a predetermined position.

[0007]

In the revolving parking device according to the present invention, when the sprocket is rotated by the drive motor while the vehicle is mounted on the parking pallet, a force in the direction of rotation of the sprocket is applied to the chain meshing with the sprocket. , The parking pallet to which the drive motor is attached relatively turns in the direction opposite to the rotation direction of the drive motor. As a result, the direction of the vehicle riding on the parking pallet is changed, so that an extra space for turning back the steering wheel is not required, and the parking space can be reduced. In addition, since the parking pallet is directly driven by the chain, the parking pallet can be reliably turned without being affected by the road surface condition where the wheels roll. In addition, one end of the chain slightly protrudes from the parking pallet, and most of the chain is fixed to an installation surface covered with the parking pallet, and a sprocket and a drive motor meshing with the chain are attached to the side outer surface of the parking pallet. Since there is no space for mounting a drive motor or a chain on the installation surface serving as a parking space in addition to the space for mounting a parking pallet. Furthermore, the chain attached to the installation surface is guided by the guide plate in an arc shape so as to substantially follow the rotation trajectory of the sprocket, and the chain and the sprocket are securely engaged with each other when the parking pallet turns, and excessive force is applied to the chain. The chain will not break or break. Also, the parking pallet is configured to stop accurately and reliably at the position where the parking pallet protrudes toward the road side and at the parking storage position by controlling the drive motor based on the detection signal from the detection means, and to drive the drive motor by remote control. In addition, when operating the parking pallet, the vehicle can be stored in the parking position while the driver's vehicle is in the riding state, and the operability is excellent.

A pair of left and right slope plates 10 for eliminating a step between the pallet 2 and the installation surface A is attached. This slope plate
10 is formed in a fan shape so that it gradually expands from the rear end of the parking pallet 2 toward the front end, and is installed only when the vehicle C rides on to prevent interference with the installation surface A during turning. The parking pallet 2 is vertically supported by a plurality of leaf springs 11 fixed to the rear end of the parking pallet 2 so as to be in contact with the surface A and to be slightly lifted from the installation surface A after the vehicle C passes. It is pivotally mounted.

A guide plate 12, which is formed in an arc shape so as to substantially follow a locus of a sprocket described later attached to the parking pallet 2, is fixed to the installation surface A of the parking pallet 2. Both ends of a chain 13 for driving the parking pallet 2 are fixed to the section. In addition, as shown in FIG. 4, the guide plate 12 is located below the parking pallet 2 in the storage state of the parking pallet 2 and is almost covered with the parking pallet 2. A forward / reverse rotation type drive motor 15 in which a sprocket 14 is fixed to a drive shaft 15A is fixed to a side outer surface of the parking pallet 2 corresponding to an extension portion of the guide plate 12 so as to extend outside. ing. Then, as shown in FIGS. 1 and 4,
The chain 13 laid on the guide plate 12 is
The chain wound around the sprocket 14 of the drive motor 15 via the relay idle sprocket 14A which is supported near the both sides of the parking pallet 2 and supported on the back surface of the parking pallet 2, and thus meshed with each sprocket 14, 14A 13 guide board

In this case, in order to align the guide plate 12 on which the chain 13 is erected along the locus of the sprocket 14, when the shaft portion 1 and the guide plate 12 are fixed to the installation surface A, the guide plate 12 and the shaft portion 1 The base plate 1A is connected to the base plate 1A by a transfer plate 17. After the guide plate 12 is fixed to the installation surface A, the bearing 5 of the parking pallet 2 may be mounted on the shaft portion 1 with the transfer plate 17 removed.

A control box 18 having a built-in control mechanism (not shown) for the parking pallet 2 is assembled outside one end of the parking pallet 2.
Two limit switches 19 and 19A are attached below the vehicle as detecting means for detecting the turning angle of the parking pallet 2,
On the other hand, on the base plate 1A of the shaft portion 1, there is provided a detection arm piece 2 which comes into contact with the actuators 20, 20A of the limit switches 19, 19A.
1,21 A is fixed. The drive motor 15 is covered by a protective cover 22. The drive motor 15 receives a signal from a remote control device (not shown) carried by the driver by a receiving means (not shown) attached to an appropriate place of the parking pallet 2, for example, a support 9A of the reflection mirror 9, The drive motor 15 is configured to be remotely operated.

The operation of the present invention will be described with respect to the above configuration. The case where the vehicle C is parked will be described with reference to FIGS. First, when a signal is transmitted from the remote control device carried by the driver to the receiving device, the drive motor 15 is activated.
When the drive motor 15 is started, the sprocket 14 integrally mounted on the drive shaft 15A rotates counterclockwise, and the chain 13 meshing with the sprocket 14 is pulled in the rotation direction of the sprocket 14. Since the parking pallet 2 to which the drive motor 15 is fixed is relatively fixed to the shaft A, the parking pallet 2 is rotated clockwise (in the direction of the arrow a in the drawing) about the shaft portion 1. Together with the limit switch mounted on the back side of the control box 18.
19,19 A also rotates in unison. Then, when the operator 20 of the one limit switch 19 contacts the one arm piece 21, the drive motor 15 stops in a state where the parking pallet 2 is inclined about 35 degrees toward the road R as shown in FIG. In this manner, the vehicle C rides on the parking pallet 2 in a state where the parking pallet 2 protrudes toward the road R. When the vehicle C gets on, the slope plate 10 is formed into a fan shape with a wide forward front side of the vehicle C, so that it is easy to enter the parking pallet 2 and the reflecting mirror 9 attached to the parking pallet 2 makes the parking pallet 2 The relative positional relationship with C can be grasped. Moreover, there is no danger of derailing due to the guide pipes 7 provided on both sides of the parking pallet 2. Then, the engine of the vehicle C is turned off with the front wheel or the rear wheel of the vehicle C hitting the wheel stopper 8 and completely riding on the parking pallet 2, and the drive motor 15 is operated again by the remote control device. In this case, the driving motor 15 rotates in the reverse direction and rotates clockwise, and the parking pallet 2 rotates counterclockwise around the shaft 1 (arrow b in the drawing).
Direction), and the actuator of the other limit switch 19A
When 20A comes into contact with the other arm piece 21A, the drive motor 15 stops at the parking pallet 2 in the storage position. As a result, FIG.
As shown in FIG. 7, the vehicle C can be parked at the storage position. on the other hand,

Further, according to the present invention, a chain 13 which meshes with a sprocket 14 attached to the side outer surface of the parking pallet 2 is stretched on the ground plane A along the trajectory of the sprocket 14 by the guide plate 12 and the guide rail 16. By rotating the parking pallet 2 by the drive motor 15 and rotating the parking pallet 2 by the chain 13 at a predetermined angle around the shaft portion 1, the parking pallet 2 is not affected by road surface conditions such as steps at the parking position and freezing of the road in winter. , The parking pallet 2 can be reliably turned. The chain 13 stretched on the grounding surface A has one end slightly extending outside the parking pallet 2, but most of the chain 13 is disposed on the back side of the parking pallet 2. Separately, there is no need to secure a mounting space for the chain 14 that drives the parking pallet 2, and a narrow parking space can be effectively used. Further, since the drive motor 15 is attached to the side outer surface of the parking pallet 1, the parking pallet 2 can be formed flat without collision between the drive motor 15 and the vehicle C riding on the parking pallet 2. Riding of the vehicle C is also easy. In addition, since the engagement position of the sprocket 14 and the chain 13 is always exposed to the outside of the parking pallet 2 and the fixed portion at one end of the chain 13 is exposed to the outside, even if an unexpected situation such as a power failure occurs, the chain 13 Easily remove the chain 13
The connection between the vehicle and the sprocket 14 can be easily released, so that the parking pallet 2 can be easily moved manually even when a power failure occurs while the parking pallet 2 is overhanging on the road side. Furthermore, limit switch 19,
The parking pallet 2 is moved to the vehicle C based on the detection signal from 19A.
When the vehicle C is stored, the parking pallet 2 stops accurately and reliably at the position where the parking pallet 2 protrudes to the road side and at the parking storage position, and the drive motor 15 is remotely operated when the vehicle C is stored. Accordingly, when the parking pallet 15 is operated, the vehicle C can be stored in the parking position while the driver's vehicle is in the riding state, and the operability is excellent.

As described above, one embodiment of the present invention has been described in detail. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the basic structure of the parking device is set as appropriate, such as the shape of the slope plate and the guide for preventing derailing, the mounting position of the reflecting mirror, the presence or absence of it, and the wheels mounted on the back of the parking pallet mounted on the side of the parking pallet do it. In the above embodiment, the turning angle of the parking pallet is set to 35 degrees, but the turning angle may be appropriately set in accordance with the relative positional relationship between the installed parking space and the road surface. Also, an example has been described in which the sprocket that meshes directly with the chain is fixed to the drive shaft of the drive motor, but the rotation of the drive motor may be transmitted to the sprocket via a transmission mechanism such as a gear.
