BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric three-wheel type wheelchair operated by an elderly person or a person with weak lower limbs.

[0002]

2. Description of the Related Art Generally, an electric three-wheeled vehicle has a floor surface in front of a driver's seat, and a person puts his / her foot on the floor surface and operates a front steering wheel. At this time, the handle shaft connected to the front wheel shaft stands upright between the legs so that the handle can be freely gripped without bending the waist. Further, Japanese Utility Model Laid-Open No. Sho 62-189726 proposes a rotating seat in which the body can be freely oriented.

The electric three-wheeled wheelchair 1 shown in FIG.
A driving power source 3 is loaded on the vehicle, and a seat 4 is provided on the driving power source 3. A floor surface 5 is formed in front of the seat 4, a front wheel shaft cover 6 projects in the center, and a handle shaft 7 is erected to be connected to the front wheel shaft in the front wheel shaft cover 6. When the user sits on the seat 4, the feet 8 shown by the chain double-dashed line are located on the floor surface 5.

Further, an electric tricycle having a floor with a space where the handle shaft is located in front of the feet and both feet are aligned, and a windshield is attached to the front end of the floor to protect the feet from direct wind. There is something I did.

[0005]

However, in the above-mentioned electric tricycle, the body and limbs can be freely moved, but when running on steps, uneven roads, gravel roads, etc., old people and people with weak legs will be impacted from the road surface. There is a risk that your body will lose its balance when your feet fall off the floor. SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric three-wheel type wheelchair in which, in order to solve the above-mentioned drawbacks, it is possible to prevent the user from stepping on his / her feet due to vibration during traveling.

[0006]

This invention SUMMARY OF THE INVENTION In order to achieve the above object, the floor front center of the driver's seat forward, prior to the vehicle body
The width in the left-right direction is narrower than the length in the rear direction, and
A side surface with the front end along with the rear surface standing upright with an approximately forward inclination.
A substantially trapezoidal support box is provided, and each side edge of the support box and the floor front
Form a footrest with a forward rising slope between the side edge of the part and upright
The lower part of the handle shaft is supported by the support box and
A handle that extends to the left and right on the upper end of the handle shaft, before
Along the front and top of the support box, from the front side edge of the floor
Attach a rear cover that extends upward and attach the cover.
The opening surface of the bar open rear is approximately flush with the rear surface of the support box.
Characterized in that the.

Can be moved to.

[0008]

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIGS.
It will be described with reference to the drawings. FIG. 1 shows an overall view of the electric three-wheel type wheelchair of the present invention. In the figure, an electric three-wheeled wheelchair 9
Is a floor surface 1 in which the handle shaft 12 is connected to the shaft 11 of the front wheel 10.
It sticks out from 3. Further, a drive means for driving the rear wheels 14 is provided inside the vehicle body cover 15, and the seat 16 is attached to the upper portion of the vehicle body cover 15. Upper end of handle shaft 12
The bar handle 17 that extends in the left-right direction of the vehicle body is
It is attached. In addition, the front of the floor surface 13 has a rear opening.
A cover 18 that is curved to speak is attached
It

As shown in FIGS. 2 and 3, the floor surface 13
Align the front end with the center of the front end, and the front
A support box 19 having a substantially trapezoidal side view that is long in the front-rear direction of the vehicle body and has an inclined standing surface is provided . This support box 19 is on the floor 1
3 to support the handle shaft 12 protruding from
ing. In addition, each side edge of the support box 19 and the front side of the floor surface 13
A footrest with an upward slope is formed between the edge and the edge. Mosquito
The bar 18 opens rearward along the front and top surfaces of the support box 19.
Release and extend upward from the front side edge of the floor 13 to support box
19 and covers the lower edge of the cover 18 along the edge of the floor surface 13.
It is fixed at screws or welding me. And hippo
The rear opening surface of -18 is almost the same as the rear surface of the support box 19.
On the face.

The electric three-wheel type wheelchair 9 constructed as described above is supported when the driver sits on the seat 16 and inserts the foot F into the cover 18 and places it on the footrest portions on both sides of the support box 19.
If you move your feet around the box 19, the edge of the cover 18 will be supported.
Operates because it is almost the same as the rear surface of the box 19 and does not project rearward
It does not get in the way of the car and makes it easy to get on and off. Also, abbreviation
Stabilize trapezoidal support box 19 to stabilize handle shaft 12
Therefore, by grasping the steering wheel 17, the driving posture can be easily adjusted.
Keep and keep your feet off the floor 13 due to the inclination of the foot rest
Less often. When the electric three-wheeled wheelchair 9 is driven in this state , even if the vehicle body swings on the uneven road, the foot and the floor 1
Not too far from 3 and the foot also touches the cover 18
In not be jumping out, this balance of running is lost
And prevent.

Further , the front end of the cover 18 is attached to the floor surface 13.
The vehicle body is strengthened by welding or screwing to the front side edge, and the appearance is also improved due to the shape of the cover 18. Also, since it covers only the foot , just before the handle shaft
You can see the road surface of
It
