CONSTITUTION:After the wheel contacting rollers 27 and 42 of right and left bogies 3 and 5 which are connected integrally by a connecting member 6 are placed in the braked condition, the driving wheels 2 and 4 of an automobile 1 are carried onto said wheel contacting rollers 27 and 42. After the braked condition of the wheel contacting rollers 27 and 42 is released, if the driving wheels 2 and 4 of the automobile 1 are driven, the driving wheels 2 and 4 are idled along with the wheel contacting rollers 27 and 42 and the transmission of the left wheel contacting roller 27 is transmitted to the travelling wheel 17 of the bogie 3 via a revolution transmitting mechanism 31. The bogie 3 is therefore carried in the laternal direction and the bogie 5 is pulled in the same direction. As a result, the automobile 1 is turned through a certain point adjacent to both the non-driven wheels 51 and 52, which are kept in the grounded state, to change the direction of the automobile 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that can change the direction of an automobile in a substantially fixed position when the automobile is taken into or out of a garage.

(Prior art) Conventionally, for example, when changing the direction of a car in a fixed position in front of the entrance to a multi-story parking lot, the four wheels of the car were placed on a large circular electric turntable, and the turntable was rotated. By moving, the direction of the car is changed.

[Problem that the invention seeks to solve]

The above-mentioned conventional electric turntable is easy to move cars onto and off the table, and can safely rotate cars that are stationary in a fixed position. However, the electric turntable itself needs a large diameter and requires a large installation space, and the mechanism that supports and rotates the large diameter table is also large. However, since it is electric, additional electrical work is required. For this reason, such a turntable-type orientation device is not suitable for general household use, and is rarely installed for personal use.

SUMMARY OF THE INVENTION An object of the present invention is to provide a simple vehicle turning device that can be used personally at home.

[Means for solving problems]

The present invention connects the truck 3 on one side and the truck 5 on the other side with a connecting member 6.
The bogie 3 on one side rotatably supports a pair of contact wheel rollers 25.27, and the pair of contact wheel rollers 25.27 drive the driving wheel 2 on one side of the automobile 1.
Further, the driving wheels is, ie of the truck 3 are mounted in a direction perpendicular to the driving wheel 2.

17 is rotatably supported, and the rotation shaft 23 of the contact wheel roller 27 and the rotation shaft 14 of the drive wheel 17 are connected to the rotation transmission mechanism 3.
Connect by 1. The other side truck 5 rotatably supports a pair of contact wheel rollers 41.42, and supports the other side drive wheel 4 of the automobile 1 by the pair of contact wheel rollers 41.42. It is movable by a free wheel 43. [Operation] The present invention applies brakes to the contact wheel rollers 27 and 42 of both bogies 3 and 5, and connects the drive wheels 2 and 4 of the automobile 1 between the contact wheel rollers 25 and 41.42. When the driving wheels 2, 4 of the automobile 1 are driven by driving the vehicle 1, such as by releasing the brake, the driving wheels 2, 4 idle rotate on the contact wheel rollers 25.27 and 41.42, and one The rotational force is frictionally transmitted to the contact wheel roller 27 of the truck 3. The rotation of this contact wheel roller 27 is transmitted to the drive wheel 17 of this truck 3 via the rotation transmission mechanism 31, and this truck 3, while supporting the drive wheel 2 of the automobile 1, shifts the drive wheel 2 laterally. Move like this.

The other truck 5 moves laterally to follow the one truck 3 while rotatably supporting the other drive wheel 4 .

At this time, since the non-drive wheels 51.52 are in contact with the ground, the automobile 1 rotates around a fulcrum near the non-drive wheels 51.52 and changes its direction. When starting the car, the car 1 is lowered from the truck 3.5 by applying a brake to the contact rollers 27.42.

(Example) Next, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a connecting member 6 such as a pipe connects a bogie 3 on one side that supports the drive wheels 2 on one side of the automobile 1 and a bogie 5 on the other side that supports the drive wheels 4 on the other side. to connect integrally.

As shown in FIG. 2, one side of the cart 3 has a frame member 11
Two driving wheel rotating shafts 13.14 are rotatably held by upper bearings 12 fixed to four corners of the shaft, and driving wheels 15.16 are provided at both ends of one of the rotating shafts 13, and driving wheels 15.16 are provided at both ends of one rotating shaft 13. A drive wheel 17 is provided at the center of the other rotating shaft 14, and auxiliary wheels 18 are provided at both ends of the other rotating shaft 14. The driving wheels 15 and 16 at both ends are rotatably fitted to the rotating shaft 13, so that they can correspond to the circular motion of the truck 3, and the central driving wheel 17 is connected to the rotating shaft 13.
4 so that it can be rotated by this rotating shaft 14. The auxiliary wheels 18 at both ends are ground wheels in case the stability of the three drive wheels 15.16.17 is impaired, and are formed to have a slightly smaller diameter than the drive wheels 15.16.17 having the same diameter. .

Furthermore, this one-side truck 3 has a roller rotation axis perpendicular to the drive wheel rotation axis 13° 14 by means of lower bearing portions 21 that are integrally attached to the lower side of the upper bearing portion 12 at the four locations. 22 and 23 are held below the drive wheel rotation shaft 13° 14, and one contact wheel roller 25 is rotatably fitted to the center of one of the roller rotation shafts 22 via a bearing 24. The other contact roller 27 is integrally fitted into the center of the other roller rotating shaft 23 using a key 26. The reason why the roller rotation shafts 22 and 23 are provided on the lower side is to bring the contact wheel rollers 25.27 as close to the ground as possible.
The center is formed to have a gradually smaller diameter so that it can come into close contact with the full width of the drive wheel 2.

Furthermore, this one side truck 3 connects the rotating shaft 23 of the contact wheel roller 27 and the rotating shaft 14 of the driving wheel 17 through a rotation transmission mechanism 31. This rotation transmission mechanism 31 is a worm gear A7 device, and a worm is formed in a part of the roller rotation shaft 23, and the worm and the hole 32
A worm wheel 33 that meshes through the drive wheel rotation shaft 14 is integrally fitted to the drive wheel rotation shaft 14. Then this one A-
The rotation of the roller rotation shaft 23 is decelerated by the mugya device and transmitted to the drive wheel rotation shaft 14. The rotation of the roller rotation shaft 23 can be selectively stopped by a brake 34.

In addition, as shown in FIG. 1, the cart 5 on the other side rotatably supports a pair of contact rollers 41 and 42 between the frame member 40, and further includes four free wheels provided on the lower surface. (caster)
43, it can be moved in any direction.

The reason why the cart 5 on the other side can move freely is that the rotational speeds of the drive wheels 2 and 4 on both sides of the car are not necessarily the same due to the differential carrier (differential gear) provided between them. In that case, if the driving wheels 2 and 4 on both sides drive the bogies 3.5 on both sides at different speeds, the two bogies 3 and 5
are interfering with each other, which is not desirable, so one of the trolleys 3
Only one of the carriages 3 is forcibly driven, and the other carriage 5 is made to freely follow one of the carriages 3 by means of a connecting member 6.

Note that the brake 34 does not necessarily need to be provided.

Then, either apply the brake 34 or apply the contact wheel roller 27.
42 and the frame member 11.44, or
Alternatively, by stopping the drive wheel 17 with a movable locking part so that the drive wheel 17 does not rotate, the contact wheel rollers 27, 42 of both bogies 3 and 5 and the drive wheel 17 of one of the bogies 3 can be used.
, and ride the drive wheels 2 and 4 on both sides of the automobile 1 between the contact wheel rollers 25, 27 and 41° 42 of both bogies 3 and 5 via an inclined plate, etc., as shown in Fig. 3. .

Then, when the brake 34 etc. are released and the accelerator pedal of the automobile 1 is depressed to drive the driving wheels 2.4 at an accelerated speed, the driving wheels 2, 4 are moved to the contact wheel rollers 25, 27 and 41.
．． 42, and frictionally transmits rotational force to the contact roller 27 of one of the carriages 3. The rotation of this contact roller 27 is
It is transmitted to the driving wheel 17 via the rotating shaft 23, the rotation transmission mechanism 31, and the rotating shaft 14, and this driving wheel 17 becomes a driving wheel, and the bogie 3 supports the driving wheel 2 of the automobile 1. Move it sideways. At the same time, the other truck 5 moves laterally to follow the one truck 3 while rotatably supporting the other drive wheel 4 .

On the other hand, the non-driving wheels 51 and 52 of the automobile 1 are in direct contact with the ground, etc., and are in a state where they can rotate freely, so the fulcrums near the non-driving wheels 51 and 52 are The entire vehicle rotates so that the drive wheels 2 and 4 draw an arc around the center, and the direction of the vehicle can be changed in any direction. When starting the automobile 1, the contact wheel roller 27 is
．． 42, and lower the car 1 from the trolley 3.5 with its own blade.

〔Effect of the invention〕

According to the present invention, the drive wheels on both sides of the automobile are supported by two bogies integrated by a connecting member, and the drive wheel on one side drives the contact wheel row provided on the bogie on the other side. The drive wheels of this truck are driven via a rotation transmission mechanism, and the truck is driven in a direction perpendicular to the drive wheels of the car, so the car rotates with respect to the non-drive wheels that are on the ground. You can change direction. Since the above-mentioned trolley does not have its own drive device and is small and simple, supporting only the drive wheels of a car, it is easy to transport and handle, and is not subject to restrictions on where it can be used. It can be used for personal use in ordinary households. Furthermore, the other side's bogie rotatably supports the drive wheels of the car with its contact wheel rollers, and can move in any direction with its free wheels, so the other side's bogie is attached to the one side's bogie. The two carts can move smoothly because they only follow one another and there is no risk of them going against one cart or interfering with the other.
