Abstract

PROBLEM TO BE SOLVED: To run drawing a small cart by a bicycle, a motorcycle, etc., on a general road or an narrow alley, etc. SOLUTION: This cart drawn tracing the rut of a rear wheel by arranging a universal joint at an about intermediate bent point between the rear wheel axles of the bicycle, the motorcycle, etc., and the small rear car axle can travel in a sharp curved corner or the narrow alley, to ensure safety and stability at the time drawing the light and small trailer.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for towing a small rear car on a bicycle, a motorcycle or the like, a mounting position, a connecting method, and a shape of the device.

[0002]

2. Description of the Related Art Conventionally, the shape of a rear car is large and heavy, and the towing position is high. The braking force when stopping is extremely reduced,
Towing a general road with many cars is very insecure and insecure and involves a great deal of danger.

[0003]

SUMMARY OF THE INVENTION In order to eliminate the drawbacks of the present invention, the entire rear car is light and small, and anybody can easily tow with a bicycle, motorcycle, etc., and can easily connect and disconnect the vehicle. The purpose of this study was to maintain the safety and stability at the time of stopping and to use it in daily life.

[0004]

SUMMARY OF THE INVENTION In order to achieve the object of the present invention, in order to hold the towing of a small rear car at a low position,
At the end of the rod formed in the shape of a letter, a fixing plate with a bent U-shaped tip at the center and a bolt hole is provided at the center, and a hook provided with a clasp at the rear end is used for bicycles, motorcycles and other rear wheels. It is sandwiched between the axle and the outside of the body bone from behind horizontally, and it is attached to the body with a nut together with the rear wheel to set the towing position low.

[0005] An elevator for adjusting a height difference of a connecting position which changes according to the size of a wheel towed by a vertical bar, and a universal joint which moves up and down, turning, and right and left in a three-variable bending motion, provided at the front center of a small rear car. Through.

[0006] Connection and disconnection work of small rear car is U
Hang the pin in front of the universal joint on the hook at the rear end of the
It is a simple operation that only locks the clasp on the hook.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a U-shaped towing device 3 having a fixed plate 2 provided on a rear axle 1 of a bicycle, a motorcycle or the like is sandwiched from behind horizontally and mounted, so that the towing of a small rear car is set to a low position. Between the hook 4 and the universal joint 7, up and down, between the universal joints 7, and between the universal joint 7 and the vertical bar 9. Exercise left and right with. The vertical movement of the height difference between the small rear cars produced by the size of the towing vehicle tires is adjusted by the elevator 8. A built-in compression coil spring exerts a push-back action so that the clasp 6 that moves back and forth due to the vibration during running does not come off, and a locking plate 5 with a lock hole is provided on the upper part.

In FIG. 2, a rear axle 1 and a small rear
A universal joint 7 which becomes a bending point almost at the center of the car axle 10
Was placed.

[0009]

According to the present invention, the U-shaped towbar is always mounted on the rear axle of the main body of a bicycle, a motorcycle or the like without any trouble, and is connected to a small rear car. To do this, it is easy to hang the front of the universal joint on the hook at the rear end of the U-shaped towbar from above, lock the clasp, and release it by simply opening the clasp and pulling up.

[0010] Since the universal joint serving as a bending point is disposed almost at the center between the rear wheel axle and the small rear car axle, the small rear car is towed so as to follow the rut of the rear wheel of the towing vehicle.
Uses a rear car that is lightweight and compact for adults and children with less physical strength, and can be towed on sharp turns and narrow alleys without worrying about the rear car. Enabled.

A universal joint is provided between the U-shaped towing unit installed at a low position and the small rear car, and the three torsional movements of up, down, turning, and left and right are operated, so that the towing vehicle is running or stopped. Even if the vehicle rolls over due to a crosswind, the connected small rear car does not roll over, preventing the cargo from falling and damaging, ensuring safety and stability.
