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.

[Conventional technology]

Conventionally, when changing the direction of a car in a fixed position, for example 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. I'm trying to change direction.

[Problem that the invention seeks to solve]

The above-mentioned conventional electric turntable has the following features: it is easy to get on and off the table with a car;
Because it can safely turn a stationary car in a fixed position, it is suitable for commercial use where many cars are turned around one after another, but the electric turntable itself needs a large diameter and requires a large installation space. The mechanism that supports and rotates the large-diameter table is also large, and it takes a lot of time and money to install it, and 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 The object of the present invention is to provide a simple vehicle turning device that can be used privately at home.

[Means for solving problems]

In the present invention, the one side truck 3 and the other side truck 5 are integrally provided by a connecting member 6, and the one side truck 3 has a pair of contact rollers 25 and 27 rotatably mounted on an axis. The driving wheels 2 on one side of the automobile 1 are supported by the pair of contact wheel rollers 25 and 27, and the movable wheels 15, 16, 17 is rotatably supported, and the rotation shaft 23 of the contact wheel roller 27 and the rotation shaft 14 of the movable wheel 17 are connected by a rotation transmission mechanism 31.
Further, the cart 5 on the other side has a pair of contact rollers 4
1 and 42 are rotatably supported, and the driving wheel 4 on the other side of the automobile 1 is supported by a pair of contact wheel rollers 41 and 42, and is movable by a free wheel 43.

[Effect]

The present invention provides contact rollers 2 of both carts 3 and 5.
The driving wheels 2 and 4 of the automobile 1 are placed between the contact rollers 25 and 27 and between the rollers 41 and 42 by applying the brakes to the rollers 7 and 42, and then the driving wheels of the automobile 1 are removed by, for example, releasing the brakes. When driving wheels 2 and 4, these drive wheels 2 and 4 contact rollers 25 and 27.
The trolley 3 rotates idly on the top and 41, 42, and
The rotational force is frictionally transmitted to the contact wheel roller 27. The rotation of this contact wheel roller 27 is transmitted to the movable wheel 17 of this truck 3 via a rotation transmission mechanism 31, and
supports the drive wheels 2 of the automobile 1 and moves so as to shift the drive wheels 2 laterally. Other trolley 5
moves laterally to follow the one truck 3 while rotatably supporting the other drive wheel 4.

At this time, since the non-driving wheels 51 and 52 are in contact with the ground, the automobile 1 rotates around a fulcrum near the non-driving wheels 51 and 52 and changes its direction. When starting the car, the car 1 is lowered from the trolleys 3 and 5 by applying brakes to the contact rollers 27 and 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. integrally connected by.

As shown in FIG. 2, the cart 3 on one side rotatably holds two movable wheel rotation shafts 13 and 14 by upper bearings 12 fixed to the four corners of the frame member 11. Moving wheels 15 and 16 are provided at both ends of one rotating shaft 13, and the other rotating shaft 14 is provided with moving wheels 15 and 16 at both ends.
A moving wheel 17 is provided at the center of the rotating shaft 14, and auxiliary wheels 18 are provided at both ends of the other rotating shaft 14. The movable wheels 15 and 16 at both ends are rotatably fitted to the rotating shaft 13, respectively, so that they can correspond to the circular motion of the truck 3, and the movable wheels 15 and 16 at the center
7 is integrally fitted onto the rotating shaft 14 and is connected to the rotating shaft 14.
to allow rotation. The auxiliary wheels 18 at both ends are grounding wheels in case the stability of the three moving wheels 15, 16, 17 is impaired, and are formed to have a slightly smaller diameter than the moving wheels 15, 16, 17 having the same diameter. .

Furthermore, this one-side cart 3 is connected to the movable rotating shaft 1 by lower bearing parts 21 that are integrally attached to the lower sides of the upper bearing parts 12 at the four locations.
Roller rotation shafts 22 and 23 perpendicular to the moving wheel rotation shafts 13 and 14 are held below the movable wheel rotation shafts 13 and 14, and one contact wheel roller 25 is connected to the center of one of the roller rotation shafts 22 via a bearing 24. It is rotatably fitted, and the other contact roller 27 is integrally fitted to the center of the other roller rotation shaft 23 by means of 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 and 27 as close to the ground as possible. The center is gradually made smaller in diameter so that it can fit closely.

Further, this one-side cart 3 is connected to the rotation shaft 23 of the contact wheel roller 27 and the rotation shaft 14 of the movable wheel 17.
and are connected by a rotation transmission mechanism 31. This rotation transmission mechanism 31 is a worm gear device, and includes a worm formed in a part of the roller rotation shaft 23, and a worm wheel 33 that meshes with the worm through a hole 32 and is connected to the movable wheel rotation shaft 14.
It is integrally fitted into the This worm gear device decelerates the rotation of the roller rotation shaft 23 and transmits it to the movable 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.
2 is rotatably supported on a shaft, and can be moved in any direction by means of four free wheels (casters) 43 provided on the lower surface.

The reason why the cart 5 on the other side can move freely in this way is that the rotational speed of the drive wheels 2 and 4 on both sides of the car is controlled by a differential gear provided between them. In that case, if the drive wheels 2 and 4 on both sides drive the bogies 3 and 5 on both sides at different speeds, the two bogies 3 and 5 will interfere with each other. Since this is not preferable, 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 the connecting member 6.

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

Then, apply the brake 34, insert a locking member between the contact wheel rollers 27, 42 and the frame members 11, 44, or lock the movable wheel 17 so that it does not rotate. By stopping with a stopper member, the contact rollers 27 and 4 of both carts 3 and 5 are
2 and one of the bogies 3 are fixed, and the drive wheels 2, 4 on both sides of the automobile 1 are connected between the contact wheel rollers 25, 27 and 41, 42 of both bogies 3, 5 via an inclined plate or the like. The vehicle runs over the vehicle as shown in Figure 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 idle rotate on the contact wheel rollers 25, 27 and 41, 42. The rotational force is frictionally transmitted to the contact wheel roller 27 of one of the trolleys 3. The rotation of this contact roller 27 is caused by the rotating shaft 23,
Moving wheel 17 via rotation transmission mechanism 31 and rotating shaft 14
The movable wheels 17 serve as driving wheels, and the trolley 3 moves so as to shift the driving wheels 2 of the automobile 1 laterally while supporting the driving wheels 2 of the automobile 1 thereon. 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
is in direct contact with the ground, etc., and is in a state where it can rotate freely, so that the driving wheels 2 and 4 draw an arc around the fulcrum near the non-driving wheels 51 and 52. The entire vehicle rotates, and the direction of the vehicle 1 can be changed in any direction. When starting the car 1, the contact wheel rollers 2 are
By applying the brakes on wheels 7 and 42, the car 1 is lowered from the trolleys 3 and 5 by itself.

〔Effect of the invention〕

According to the present invention, two parts are integrated by a connecting member.
The drive wheels on both sides of the car are supported by a bogie, the drive wheel on one side drives a contact wheel roller provided on the one side of the bogie, and the movable wheels of this bogie are driven via a rotation transmission mechanism, Since the truck is driven in a direction perpendicular to the driving wheels of the automobile, the automobile can rotate and change its direction with respect to the non-driving wheels that are in contact with the ground. Since the above-mentioned trolley does not have its own drive device and is small and simple, supporting only the drive wheels of the car, it is easy to transport and handle, and there are no restrictions on where it can be used. It can be used for personal use in general 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. It only moves by following the cart on one side, and there is no risk of it going against the cart on one side or interfering with each other.
The trolley can be moved smoothly.
