JPH08310471A - Roof supporter of small saddle-type vehicle - Google Patents

Abstract

PURPOSE: To enhance the extent of rigidity in the roof supporting structure of a small saddle-type vehicle as well as to perform a stable smooth handle operation. CONSTITUTION: This is a roof supporter of a small saddle-type vehicle, which is made up of situating a roof supporting rod 7 of at the front end lower part of a roof 5 covering the upper part of a drive's seat 5 at the rear-wheel side, in the upper part of an upper end extension of a shaft 3 of a handle 2 being free of steering a front wheel, and supporting it via a bearing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof support device for a small vehicle. It can be used for a small electric vehicle or the like which has front wheels under the handle shaft and is steerable.

[0002]

2. Description of the Related Art Some small vehicles driven by an engine, an electric motor, or the like are provided with a roof covering the driver's seat for protection from rain and sun. Since it is supported only from the vehicle body side at the rear of the driver's seat, it is unstable and it may be difficult to perform driving operation.

[0003]

According to the present invention, a roof supporting rod at a lower front end of a roof 6 covering a driver wheel 5 on a rear wheel 4 side is provided above an upper extension line of a steering wheel 2 shaft 3 capable of steering a front wheel 1. 7 is positioned and is supported by a bearing 8 to provide a roof supporting device for a small vehicle.

[0004]

The operation of the small vehicle is performed by the driver sitting on the driver's seat 5 and operating the steering wheel 2. The roof 6 is supported on the rear side of the driver's seat 5. Since the roof support rod 7 at the front end of the roof 6 is supported on the upper end of the handle shaft 3 via a bearing 8, the handle 2 and The turning of the front wheel 1 by the steering of the handle shaft 3 is performed around the handle shaft 3 and the roof support rod 7 on the extension line of the upper end of the front wheel 1 through the bearing 8. Therefore, smooth steering of the handle 2 is performed. In addition, since the roof support rod 7 is directly supported on the upper end of the handle shaft 3, the rigidity of the roof 6 is maintained, and a stable support structure and steerability are obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated example shows an electric three-wheeled wheelchair, in which a front wheel 1 that is steerable around a handle shaft 3 is provided at the front end of a vehicle body 9, and a pair of rear wheels 4 are provided at the left and right sides of the rear end. Rear wheel 4
The driver's seat 5 is mounted on the rear cover 10 that covers the upper part of the
The rear wheels 4 can travel by being driven by an electric motor mounted in the rear cover 10. A step floor 12 is formed between the rear cover 10 and the front wheel fender 11 that covers the front front wheel 1. The handle shaft 3 is made of a pipe material and is rotatably supported by a handle post 13 on the front wheel fender 11 while being inclined at an appropriate angle in the front-rear direction. The handle 2 having a suitable shape such as a loop shape, a round shape, or a bar handle is integrally attached to the upper end of the handle shaft 3. Reference numeral 14 is a handle panel integrated with the handle 2.

The roof 6 covers the upper portion of the driver's seat 5 in the front-rear direction, and the rear-end supporting leg portions 16 are used for the back seat 1.
5 has a Y-shaped support member 17 at the front end thereof, and the roof support rod 7 at the lower end of the roof support rod 7,
It is provided along an upward extension line of the handle shaft 3, and a lower end portion of the roof support rod 7 is rotatably supported inside the upper end of the handle shaft 3 with a bearing 8 such as a roller bearing interposed. Set up. 18 is a transparent sun visor. 19 is a bracket on the upper end of the handle shaft 3, 20
Is a retaining bracket so that the collar 21 integrated with the roof support rod 7 is sandwiched between the retaining bracket 19 and the retaining bracket 19 to prevent the bracket from coming off.
Tighten and fix it with bolts.

The lower part of the handle shaft 3 which is steered by the handle 2 is supported by the handle post 13, and
The upper part is supported by the roof support rod 7 at the front end of the roof 6. The handle shaft 3 and the roof support rod 7 are provided coaxially, and the upper end of the handle shaft 3 is rotatably supported and connected to the roof support rod 7 via a bearing 8. The operation is smoothly performed, and the rigidity is increased by supporting the front end portion of the roof 6, so that stable steerability can be maintained. Although the example of a three-wheel type small vehicle is shown in the figure, the same applies to a four-wheel type small vehicle that can be steered by a link mechanism provided below the handle shaft.
