Description

[Detailed Description of the Invention] The present invention relates to an improvement of a motorized tricycle equipped with a small displacement engine.

A motorized tricycle equipped with a small-displacement engine of about 50 c.c., which even children can drive, is provided, and such tricycle is transported to the destination by car and driven in fields, etc. other than public roads. Therefore, it is necessary to load and unload the vehicle into the trunk of a car.

The present invention was developed in view of the above circumstances, and its purpose is to make it possible to load and unload the vehicle into the trunk of a car by grasping the front and rear of the vehicle, making it convenient for loading and unloading, moving, and transporting. In order to provide a motorized tricycle and achieve the above objects, the gist of the present invention is to provide grips at the front and rear of the vehicle body.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a side view of a motorized tricycle 1, in which a head tube 3 is provided at the front end of a single frame 2 extending back and forth, and a front fork 6 is connected to the head tube 3 via upper and lower bridges 4, 5.
The front fork 6 is made of pipe material or the like, does not have a buffering function, and is similar to the front fork of a bicycle.

The lower end of the front fork 6 supports an axle 7a of a single front wheel 7 that serves as a steering wheel.The front wheel 7 uses a so-called balloon tire with ultra-low pressure, and the tire pressure provides a cushioning effect.A handle is mounted on the top bridge 4. 8
will be established. The handle 8 is approximately U-shaped from the front, with the lowest middle part 8a connected to the receiving part 9 on the top bridge 4.
one end of the clamper 10 is fixed to the front of the receiving part 9, and the clamper 10 has a semicircular part 10a on the front part, and the semicircular part 10a faces above the intermediate part 8a, and The extending portion 10b is loosely engaged with a tightening screw 11 screwed onto the intermediate rear portion of the top bridge 4 from above, and the extending portion 10b is pushed down by rotation of the head 11a of the screw 11, and the semicircular portion 10 of the clamper 10 is pushed down.
At step a, the handle middle part 8a is crimped onto the receiving part 9, and the handle 8 is fixed. As described above, the clamper 10 is formed of a spring steel plate or the like, and by loosening the screw 11, the crimping fixation of the handle 8 is loosened, and the handle 8 is
The handle 8 can be retracted by tilting it backward and downward using the intermediate portion 8a as a fulcrum.

A cover 12 forming a body is provided on the front and rear parts of the frame 2 so as to cover the frame, a fuel tank and the like are housed inside the front part of the cover 12, and a seat 13 is arranged on the rear part.

A power unit 16 consisting of an engine 14 and a transmission case 15 is disposed on the middle lower surface of the frame 2. The power unit 16 is fixed to the frame 2 at the front and rear upper portions, and a drive shaft extends to the left and right at the rear of the power unit 16. Rear wheels 17, 17 forming two driving wheels are provided at 16a. The seat 13 faces above between the rear wheels 17, 17, and rear fenders 18, 18 are provided on both sides of the seat 13 of the cover 12 to cover above the rear wheels 17, 17. In the drawings, numerals 19 and 19 indicate steps.

The front part of frame 2 is high, the middle part is tilted backward and downward,
The rear part faces between the rear wheels 17, 17 and is the lowest, and the rear end part is inclined rearward and upward. A rear gripping rod 20 having a substantially concave planar shape is provided at the rear end part. Looking forward from the rear end of 17. Such gripping rod 20
The gripping rod 20 is attached and supported on the frame 2 side through a symmetrical bracket 21 provided at the rear end of the frame 2 with the front ends of the left and right side rod portions 20b, 20b. Sufficient strength and rigidity can be obtained.

On the other hand, the front part of the top bridge 4 extends forward, and a horizontally long window part 4a is provided in this part.
A front gripping rod 22 is provided on the front edge of the gripping rod 22.
consists of left and right side rod portions 22b, 22b extending rearward from both ends of the front horizontal rod portion 22a and connected to the front portion of the top bridge 4. In this way, a gripping rod is formed integrally with the front part of the top bridge 4 and close to the head tube 3 into which the screw head 11a is screwed, as shown in FIG. Since the rod is integrated with the top bridge, sufficient strength and rigidity can be obtained, and since the rod is integrated with the top bridge, the number of parts is reduced, and although a gripping rod is provided, there is no need for an installation process. In addition, 2 in the drawing
3 is the front fender.

FIG. 4 shows a modified embodiment, in which the left and right members 106A, 10 of the front fork 106 are
6B, that is, above the front fender, and below and in front of the top bridge 104, a gripping rod 122 is provided so as to extend between the two.
Facing the front of 06A, 106B, left and right side rod parts 1
22b, 122b are bent and extended rearward, and are joined to the left and right members 106A, 106B.

The above gripping rod 122 is also the front fork 106
Since the gripping rod is provided in the upper part, sufficient strength and rigidity of the gripping rod can be obtained during lifting and the like.

As is clear from the above, according to the present invention, since a motorized tricycle is equipped with gripping rods at the front and rear, it is possible to load and unload a vehicle by gripping the front and back, and it is easy to handle. , since the gripping rod is installed on the vehicle body side, the strength is
It is advantageous in terms of rigidity and is convenient for using this type of tricycle.

Furthermore, since the front gripping rod is provided close to the head tube, there is less vibration of the steering wheel and handle during loading and unloading, making the work easier.

Since the front gripping rod and the rear gripping rod are located approximately on the center line in the width direction of the vehicle body and grip the center of gravity of the vehicle body, good balance can be maintained during movement.
