Further, the front wheel portion 61 is provided with a handle 70 for variably setting the traveling direction of the vehicle body 50. Reference numeral 71 indicates a seat mounted on the vehicle body 50.

In consideration of its operability, both ends of the handle 70 are bent in a U shape to form a horizontal bent portion, and a grip portion 70A thereof is in front of a seat 71 as shown in FIG. Is configured to be located in the portion.

[0004]

However, in the above-mentioned conventional example, since the grip portion is provided so as to project toward the seat side, the handle operability is good, but on the other hand, the vehicle body 50 The grip 70 when getting on and off
There was an inconvenience that A got in the way.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to improve an inconvenience of the conventional example, and in particular, to provide an electric tricycle capable of smoothly getting on and off a driving operator while maintaining a good handle operability. To aim.

[0006]

According to the present invention, a front wheel portion that supports a vehicle body and guides the traveling direction of the vehicle body, and a rear wheel portion that supports the vehicle body and applies a predetermined traveling force to the vehicle body. A parking brake mounted on the rear wheel portion and a handle for variably setting the traveling direction of the vehicle body on the front wheel portion are provided.

The handle has a handle shaft portion fixedly mounted on the front wheel portion, a box body fixed to the upper end of the handle shaft portion, a horizontal handle shaft portion mounted on the box body, and It is configured to have horizontal bent portions bent toward the seat at both ends of the horizontal handle shaft portion.

The handle is equipped with a handle rotation locking mechanism for rotating at least the horizontal bent portion of the handle forward and locking it at a predetermined position. This aims to achieve the above-mentioned object.

[0009]

[Operation] First, when a driver gets on the vehicle, in a normal case, for example, the horizontal bent portion of the horizontal handle shaft portion is tilted up. If not, the rotation locking mechanism for the handle is operated to tilt up the horizontal bent portion. As a result, the distance between the horizontal handle shaft portion and the seat becomes large, and the driver can get on the vehicle smoothly even if it is rather thick.

After getting on the vehicle, the driver again operates the handle rotation locking mechanism to return the entire handle or the horizontal bent portion of the handle to the original position. This enables the driver to operate the steering wheel in a stable manner.

Tilt up D. As a result, the distance between the horizontal handle shaft portion 5C and the seat 1 is greatly increased,
At the same time, since the parking brake 4 is surely in the operating state, the driver can smoothly get on the vehicle even if it is considerably thick.

After getting on, the driving operator operates the integrated hook disengaging mechanism 11C or 12C to disengage the first and second hook mechanisms 11B and 12B, and the horizontal bending portion of the horizontal handle shaft portion 5C. Move down 5D. As a result, the parking brake 4 is released and the vehicle is set in a travelable state. At the same time, the first hook mechanism 11B is actuated to prevent the horizontal bending portion 5D from tilting up, which enables a stable steering operation by the driver.

As described above, according to this first embodiment,
During traveling, the rotation range setting mechanism section 10 and the first horizontal handle shaft fixing mechanism section 11 operate to always fix the horizontal bent section 5D of the horizontal handle shaft section 5C in a state in which the horizontal bent section 5D faces the seat. When the passenger gets on and off, the rotation range setting mechanism portion 10 and the second horizontal handle shaft fixing mechanism portion 12 are activated to set the horizontal bent portion 5D of the horizontal handle shaft portion 5C in an upward state. With the tilt-up operation of the horizontal bending portion 5D, the brake drive mechanism 7 can be operated to operate the parking brake 4, and therefore, the operation operator can smoothly get on and off and secure a stable handle operation. There is an advantage that you can.

B of FIG. 15, the front tilt position setting member 31C extending from the upper end in the front tilt direction, and the front tilt position setting member 31C.
Is formed on the back side of the U-shaped member 31B by connecting the open end of the U-shaped member 31B and the connecting plate 31D. The lower end portion of the handle support shaft portion 35A of the handle 35 has the U-shaped member 31 of the front fork mechanism 31 described above.
The part B is rotatably supported in the forward tilting direction (see FIG. 15).
The reference numeral 31a indicates a through hole for the shaft support).
First, the handle 35 can be reciprocally rotated in the forward tilt direction.

The forward tilt position setting mechanism 32 described above is mounted inside the lower end of the handle 35 pivotally supported by the front fork mechanism 31 at a position corresponding to the front tilt position setting member 31C of the front fork mechanism 31. (See FIG. 18).

The forward tilt position setting mechanism 32 includes two through holes 35a provided at the lower end of the handle support shaft portion 35A.
35a, handle stopper members 32A and 32A that engage with the through holes 31e and 31e (or 31f and 31f) provided in the front fork mechanism 31 described above, and the handle stopper members 32A are always directed outward and individually. Pressing springs 32B and 32B that press against each other, and the handle stopper members 32 against the pressing springs 32B.
The wire mechanism 32C that pulls A back inward, and the frame 32G that supports the above-described handle stopper members 32A and each pressing spring 32B are provided. Reference numeral 32E indicates an annular elastic member provided in the through holes 35a, 35a on the handle 35 side. Reference numeral 32H indicates a guide member for the frame 32G.

Therefore, the wire mechanism 32C is pulled to move the handle stopper members 32A to the handle shaft portion 35.
When the handle 35 is immersed in A, the handle 35 can be reciprocated in the forward tilt direction as a whole. When the wire mechanism 32C is loosened at the position of the through hole 31e or 31f on the side of the front fork mechanism 31 described above, the pressing spring 32B pushes the stopper member 32A for each handle outward, and the stopper member 32A for handle is released. Through hole 31e
Alternatively, the front fork mechanism 31 is engaged at the position 31f. As a result, the handle 35 is set to either the normal position or the forward leaning position.

FIG. 17 shows an example of the forward tilt operation mechanism 33 for operating the forward tilt position setting mechanism 32. This forward tilt operation mechanism 3
3 is an operation lever 33A having a structure for pulling the wire mechanism 32C described above with a predetermined stroke, and the wire mechanism 3A.
It is composed of a lock member 33B that locks the operation lever 33A in the state of pulling 2C and a spring 33a that constantly urges the lever 33A toward the original position, and is provided in the box body 35B of the handle 35 as a whole. .

Therefore, when the forward tilt position setting mechanism 32 is operated and the operating lever 33A is pressed in the direction of arrow b in FIG. 17 to engage with the lock member 33B, the forward tilt position setting mechanism 32 is pressed.
The respective handle stopper members 32A of 3 are retracted into the handle 35, whereby the handle 35 is
As a whole, the reciprocating movement in the forward tilt direction is possible as described above.

FIG. 16 shows an example of the brake drive mechanism 37 in the third embodiment. This brake drive mechanism 3
