Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a technique for parking a vehicle such as an automobile on a trolley and moving the trolley to park the vehicle at a parking position.

[Conventional technology]

BACKGROUND ART When the width of the road surface on which a vehicle such as an automobile runs is narrow, and the garage or parking space is also narrow, it is difficult to move the vehicle closer to the parking position by operating the steering wheel, switching back, or the like. Therefore, a device is used in which the vehicle is parked by riding on a trolley, and the vehicle is then parked by moving the trolley sideways.

Conventionally, such a device has been disclosed in Japanese Patent Application No. 62-99080.
There is something disclosed in the issue. In this conventional technology, a pair of rails are integrally fixed to both sides of a strong rectangular frame body to form a bogie, and a vehicle is parked on top of the bogie. Move the cart horizontally. The truck's drive device then expands and contracts the pantograph-like object.

In addition, in addition to the above-mentioned document, instead of using a pantograph-shaped drive device, a guide for horizontally moving the cart is provided on the road surface, and the cart is moved back and forth between the parking position and the road surface using a rope, threaded rod, etc. Things are also known.

[Problem to be solved by the invention]

The above-mentioned conventional technology has the problem that since the cart is moved horizontally in parallel, the cart largely protrudes from the parking position onto the road surface, and a guide or pantograph-like drive device is required to ensure parallel movement. There is.

Also, if you forget to return the trolley to the parking position after the vehicle has departed, the trolley will remain on the road, which not only obstructs road traffic, but also poses the risk of causing a traffic accident. be.

An object of the present invention is to prevent the cart from protruding significantly from the parking position, and also to eliminate the need for a guide or the like to ensure movement of the cart.

In addition to the above, a second object of the invention is to enable the carriage to be moved as close to the parking position as possible.

In addition to the above, a third object of the invention is to prevent a vehicle from leaving its trolley on the road.

[Means to solve the problem]

This invention is as follows.

1) A bearing with a vertical axis is provided at the front of the bogie on which the vehicle rides, and the bogie is rotatably supported, and the bogie is provided with rotating wheels that roll on the ground, and its axis intersects with the axis of the bearing. parking device.

2) In 1) above, the trolleys are divided into two at intervals in the front and rear, and each is provided with rotating wheels as a pair of divided trolleys. Parking device connected to.

3) In 2) above, an obstacle is provided behind one of the pair of split bogies to prevent the wheels of the vehicle from running, and the wheels of the vehicle can touch the ground between this obstacle and the one split bogie. A parking device that secures space.

[Effect]

■) The bogie carrying the stranded vehicle can rotate around the bearings with the rotating wheels supporting the entire weight.

To move a vehicle from a road parallel to the parking position to the parking position and vice versa by simply moving only one side of the trolley divided approximately diagonally from a parking position such as a garage to the road side. A vehicle traveling on the road only needs to slowly operate the steering wheel while driving slowly when it wants to run onto a bogie facing diagonally toward the road, and vice versa when starting the vehicle.

Note that depending on the surrounding road conditions, the vehicle may be moved backward and stopped, and then moved forward and started. When there are no vehicles, the trolley is stored in the parking position to ensure the freedom of general traffic on the road.

2) To explain the case where a vehicle is moving forward and tries to park, the vehicle comes to the preliminary stop position with the truck in the parking position, makes a preliminary stop, and then rotates the truck to stop the rear split truck. Insert between the front and rear wheels of the vehicle. At this time, since the connecting rod is on the parking position side of each divided truck, it is possible to insert the truck without interfering with the front wheels. Then, the vehicle is slowly driven from the preliminary stop position and placed on the trolley. Therefore, the front wheels can be prevented from stepping on the rear split bogie. After that, the truck and the vehicle are rotated and moved to the parking position. When starting the vehicle, the reverse is true; once the vehicle has backed up from the truck to the preliminary parking position and touched down, the truck can be pulled back to the parking position.

It can also be used to allow the vehicle to back up, park, and move forward to start.

Note that the preliminary stop position refers to the position of the vehicle where the bogie can be operated as described above. Same below.

3) Even if a vehicle tries to park at a preliminary stop position with its trolley on the road, or if it tries to start from the preliminary stop position with its trolley on the road, an obstacle will prevent it from crossing such a stop. Prevent departure. This also prevents the front wheels from stepping on the rear split bogie unnecessarily.

〔Example〕

1 is a plan view of an embodiment, FIG. 2 is a plan view of a different embodiment, and FIG. 3 is a view taken along arrow P in FIG.

In FIG. 1, a bearing 2 is provided at the front of a truck 1.
The trolley 1 is rotatable around a vertical axis. At the rear of the truck 1, one rotating wheel 3 is attached to the side surface, and the extension line of the rotating shaft (not shown) is the bearing 2.
Therefore, the trolley l carrying a vehicle (not shown) can rotate around the bearing 2 with its entire weight supported by the rotating wheels 3. Therefore, the vehicle can be parked on the trolley 1 at the position shown in the figure and stopped, and then rotated to the position indicated by the - dotted chain line and parked at a parking position such as the garage 4.

A sled tip 1a having a slope is attached to the truck 1 with a hinge so that the vehicle can easily ride on it, and the rotary wheels 3 are provided with a protective cover 3a. Although the drive device is not particularly shown, a known low rotational speed torque motor may be installed around the bearing 2, or an appropriate known drive device may be connected to the parking position side of the trolley 1. If there is a pair of rotating wheels 3 as shown in the figure, the truck 1 will be supported at three points on the road surface by the bearings 2 and the rotating wheels 3, and if there are three or more rotating wheels 3, the bearing 2 will bear the thrust load. You can also choose not to.

According to this embodiment, the truck 1 protrudes from the parking position only on approximately one diagonal side thereof, and the movement of the truck 1 is guided by the bearing 2 for rotation.

In the different embodiments shown in FIGS. 2 and 3, the trolley 11
consists of a pair of split carts 11a and llb, and is divided into front and rear parts. The divided trolleys 11a and llb have lengths in the longitudinal direction suitable for mounting the pair of front wheels 12a or the pair of rear wheels 12b of the wheels 12 of the vehicle, respectively. A distance A is provided between the divided carriages 11a and llb.

The divided foreign cars 11a and llb are connected to each other by a connecting rod 13 at their parking position side sides. The leading end of the connecting rod 13 is connected to the front divided truck 11a through a horizontally strong pin 14, so that the rear end can move up and down. This rear end has rotating pieces 15a, 15 that can rotate around the axis of the connecting rod 13.
b is connected to the rear divided carriage 11b, and the rear divided carriage 11b can rotate around the axis of the connecting rod 13. Eventually, the connecting rod 13 is
The pair of segmented carriages 11a and llb connected together maintain a U-shape in plan view, while the plane of the rear segmented carriage 11b has a degree of freedom relative to the plane of the front segmented carriage 11a. All split carts have rotary wheels 2 similar to those in Fig. 1.
Even if the ground from the parking position to the road surface has some unevenness or inclination, the rotary wheels 2 of each segmented truck are always in contact with the ground due to the above-mentioned degree of freedom. Front split trolley 11
a has a bearing 2 similar to that in FIG.
The entire truck 11 consisting of a and llb rotates around the bearing 2.

Note that if the ground is not very uneven or sloped, the connecting rod 13 may be rigidly connected to each divided truck by omitting the bin 14 and the rotating pieces 15a and 15b.In this case, the connecting rod 13 is a flat plate parallel to the ground. It is also possible to secure the degree of freedom by utilizing its elasticity.Furthermore, the connecting rod is not connected to the front split bogie, but is extended to bypass this, and its tip is connected to the bearing 2 or another place near it. It may also be connected to a rotation shaft.

According to such a structure, since the connecting rod 13 is on the parking position side, as explained in 2) of [Operation], when the vehicle is in the preliminary stopping position, the trolley 11 can be moved from the parking position shown by the dashed line. It can be moved in and out of a parked position and vice versa. Therefore, the trolley 11 can be taken in and out while the vehicle is closer to the parking position. In addition, it is possible to avoid unnecessary double stepping on the rear divided bogie in which the front wheels of the vehicle ride on the rear divided bogie 11b, touch down once at interval A, and then ride on the front divided bogie 11a and come to a stop. .

Further explanation will be continued regarding FIGS. 2 and 3.

An obstacle 16 is provided at the front part of the rear divided truck 11b. According to such a structure, as explained in 3) of [Operation], when parking, the trolley 11 cannot be inserted under the vehicle until the vehicle has stopped at the preliminary stop position, which prevents the vehicle from starting. Sometimes, when the vehicle has descended to the preliminary stop position, the vehicle cannot be started unless the trolley 11 is pulled out to the parking position. Therefore, the trolley 11 is not left on the road.

Further, the rear divided truck is not stepped on twice by the vehicle's wheels unnecessarily.

Note that the obstacle 16 may be attached to the connecting rod 13 as shown by a dashed line 16a. The purpose of the obstacle 16 or 16a is to prevent the front wheels 12a of the vehicle from getting off the front split bogie 11a and moving backward when the vehicle starts moving backward. That is, the obstacle 16 or 16a needs to be located behind the front segmented truck 11a to ensure enough space to position the front wheels 12a at the preliminary stop position.

Gap A is used for the space. An obstacle may be provided further behind the rear divided trolley 11b. At this time, the total length of the device becomes longer, but since the trunk of the vehicle protrudes from the rear wheels 12b of the vehicle (or the engine room from the front wheels when reversing to park), a parking space such as a garage can be used instead. The parking space is not obstructed by obstacles for the rear split trolley 11b.

〔Effect of the invention〕

According to this invention 1), a vehicle can be parked in a narrow parking position by simply moving only one side of the trolley, which is divided approximately diagonally, into and out of the road, and the protrusion of the trolley into the road can be reduced. This also has the effect of simplifying the device since there is no need for a guide to ensure movement of the cart.

According to invention 2), in addition to the above l), when the vehicle is at the preliminary stop position closer to the stop position, the bogie can be taken in and out, and the wheels of the vehicle are not wasted on the rear split bogie.
This has the effect of preventing you from stepping on it too much. Moreover, there is an effect that the rotary wheels of the split truck can always be kept in contact with the uneven road surface.

According to invention 3), in addition to the above-mentioned 2), there is an effect that it is possible to prevent the vehicle from leaving the vehicle on the road after stepping twice.
