Description

The present invention relates to a standing-type golf car having a step for standing on the rear part of a vehicle body.

[Prior art]

A golf car is a vehicle for carrying a golf bag on a golf course, and generally, a front steering wheel (front wheel) is operated while operating a steering wheel through a steering shaft.

There are two types of golf cars, one is a seating type in which a driver sits on a seat and operates a steering wheel, and the other is a standing type in which a driver stands on a step provided at a rear portion and operates a steering wheel. The latter standing type is advantageous in that it can be made smaller and simpler than the former sitting type.

However, in the case of a standing-type golf car that is characterized by miniaturization, the driver's posture leans forward and backward when going up and down a slope. Was leaning forward on the steering wheel and pulling backwards when climbing uphill. However, in the conventional steering axis support frame, it was not sufficiently recognized that such a large bending load is applied to the steering axis in the front-back direction, so that the steering axis becomes unstable during long-term use. There was a problem of becoming.

In addition, since the golf bag may fall when going up and down the slope, the steering axis support frame was sometimes used as a means for stably supporting it, but this is increasingly the case. It was a factor that made the support unstable.

[Problems to be Solved by the Invention]

An object of the present invention is to enable stable support of a steering shaft and stable mounting of a golf bag in a standing-type golf car in which a steering shaft is easily subjected to a bending load in the front-back direction while having a simple and compact support frame structure. To provide a golf car that does.

[Means for Solving the Problems]

According to the present invention to achieve the above object, a step is provided at a rear portion of a vehicle body frame, a steering wheel is provided at a front portion thereof, and a steering shaft for operating the steering wheel is obliquely installed so as to rise obliquely rearward. In a standing-type golf car in which a steering wheel provided at the upper end of the steering shaft is operated by standing on the step, a rear frame mounted and fixed on both sides of the body frame so as to stand diagonally forward. And a front frame part mounted and fixed on both sides of the vehicle body frame so as to rise obliquely rearward are connected and fixed to each other to form a steering shaft support frame, and the steering shaft support frame is provided with the steering shaft above the steering frame. A platform for supporting the upper part of the shaft rotatably around the axis and supporting the lower part of the golf bag is provided on the lower part of the body frame, and the upper part of the golf bag is mounted on the steering shaft support frame. The steering shaft and the steering shaft support frame so that the steering shaft and the steering shaft support frame project upward, and the upper surface of the steering frame is supported above the steering wheel by a resin cover. It is characterized in that a fender covering the above and a fender covering the upper part of the drive wheel are integrally formed.

In this way, the front frame part that tilts diagonally rearward, which is the same as the steering shaft, and the rear frame part that tilts diagonally forward, which is the opposite of the steering shaft, are integrally connected and fixed so as to intersect with each other. Have a structure that has rigidity and does not easily rattle. Therefore, even if the driver leans on or pulls the weight on the steering shaft through the steering wheel while traveling on a slope, the steering shaft can be stably supported for a long period of time. Further, even if the steering shaft support frame is used for mounting a golf bag or supporting the upper portion thereof, stable support of the steering shaft is not impeded.

〔Example〕

 The present invention will be described below with reference to the embodiments shown in the drawings.

In the standing type golf car shown in FIGS. 1, 2 and 5, 1 is a vehicle body frame, and 2 is a resin cover for covering the vehicle body frame 1. The vehicle body frame 1 supports a front fork 5 at the center of the front part so as to be rotatable left and right, and
One steering wheel 3 is supported on the front fork 5.

A steering shaft 6 is connected to the center of the upper portion of the front fork 5, the steering shaft 6 extends obliquely rearward, and a bar handle 7 is connected to the upper end of the steering shaft 6. A flat step 15 is provided at the rear end of the body frame 1, and a driver such as a caddy can stand on the step 15.
The driver takes the steering wheel 7 while standing in step 15.
The steering wheel 3 can be steered left and right through the steering shaft 6 by operating. A rear axle 8 is laterally provided at the rear of the vehicle body frame 1, and drive wheels 4, 4 are attached to the left and right sides of the rear axle 8, respectively.

Further, in the center of the body frame 1, two batteries 9,9
A drive motor 10 that uses the battery 9 as a power source is mounted. The drive motor 10 reduces its output by the speed reducer 11 and further transmits it to the rear axle 8 via the sprockets 12 and 14 and the chain 13 to drive the drive wheels 4 and 4.

As shown in detail in FIGS. 3 and 4, the vehicle body frame 1 is provided with a head pipe 16 at the center of the front end, and the head pipe 16 pivotally supports the upper portion of the front fork 5. A pair of main frames on the left and right sides of the head pipe 16
17 and 17 are connected, and a pair of left and right down tubes 18 and 18 are connected to the lower side.

The main frames 17 and 17 and the down tubes 18 and 18 extend rearward and are integrally coupled to the left and right back stays 19 to form a frame body. Main frame 17, down tube 18, which make up these frame bodies,
Each of the back stays 19 is composed of a square pipe.

A steering shaft support frame 24 formed of a round pipe is provided on the upper portion of the frame body thus configured. The steering shaft support frame 24 includes a rear frame portion 24a.
And the front frame portion 24b.

The left and right ends of the rear frame part 24a are fixed to the back stays 19, 19 at the rear part of the frame body, and extend obliquely forward so as to form a U-shape or a U-shape. The lower part of the front frame part 24b is fixed to the front part of the frame body at both left and right ends and extends obliquely rearward so as to have a U-shape or a U-shape. The rear frame portion 24a and the front frame portion 24b are integrally connected and fixed so that the upper portions thereof have a mountain shape.

A bracket 32 is fixed to the upper portion of the rear frame portion 24a so as to straddle an intermediate position, and the upper portion of the steering shaft 6 is rotatably supported by the bracket 32.

As described above, the steering shaft support frame 24 is configured by the front frame portion 24a and the rear frame portion 24b that are inclined in mutually opposite directions being formed by intersecting each other in a chevron shape and integrally connected and fixed together. The steering shaft support frame 24 has extremely large bending rigidity with respect to the load applied in the front-rear direction. Therefore, when going up and down the slope,
Even if the driver leans forward on the steering shaft 6 via the steering wheel 7 or pulls the weight backward, the steering shaft support frame 24 can stably support the steering shaft 6.

Further, in this embodiment, the width between the left and right arms of the rear frame portion 24a is arranged narrower than that of the frame body, and the width between the left and right arms of the front frame portion 24b is further narrowed. It is easier to secure a space for mounting the golf bag.

Also, the left and right down tubes that make up the frame body side
Horizontal frames 20, 20 are connected between 18, 18, and both lateral portions of the horizontal frames 20, 20 extend to both outsides of the down tubes 18, 18 to form projecting frame portions 20a, 20a. . The projecting frame portions 20a, 20a are located at the outer center points FC, FC 'of the front steering wheel 3 and the outer center points RC, R of the rear drive wheels 4, 4, respectively.
The line segments L and L'connecting C'on the same side of the vehicle body are formed so as to project outward from the line segments L and L '.

The left and right protruding frame portions 20a, 20a are reinforced by a vertical frame 21, respectively, and a surrounding frame 22 is assembled to form a golf bag mounting table 23. Stands 23, 23 formed on both left and right sides of the body frame
Each of the two can support the lower part of two golf bags.

On the other hand, above the platforms 23, 23, rear frame portions 24a, 24a of the steering shaft support frame 24 extend, and support frames 25, 25 and belts 26, 26 are attached to the extended frame portions, respectively. As a result, the upper part of the golf bag is fixed. That is, the steering shaft support frame 24
The (rear frame portion 24a) is used for supporting the upper portion of the golf bag through the support frame 25.

As shown in FIG. 1 and FIG. 2, the resin cover 2 covers the upper part of the frame body and forms fenders 27, 28, 28 for covering the steering wheels 3 and the driving wheels 4, 4, respectively. There is. Further, the cover 2 made of resin has a mount 29 which is recessed in the middle. Further, a resin putter case 30 is attached to the front part of the cover 2 so that a plurality of putters 31 can be stored. This putter case 30 has an opening 30a for insertion in the upper part and is provided along the steering shaft 6, so that the driver standing on the step 15 can easily put the putter 31 in that posture. Can be taken in and out.

As described above, in the standing-type golf car, the steering frame support frames 24 are fixed to the both sides of the rear portion of the vehicle body frame 1 so as to be diagonally forward and rearward.
Since 24a and the front frame part 24b fixed so as to stand diagonally rearward on both front parts of the body frame 1 are integrally connected and fixed so as to form a chevron shape, the load is applied to either the front or rear direction. However, it will exhibit great bending rigidity.

Therefore, even if the driver who has boarded the vehicle stands still in order to maintain a stable posture when traveling on a slope or the like, the steering shaft 6 is supported by the steering shaft 6 even if the weight is heavily loaded to the front or rear of the steering wheel 7. The frame 24 supports it stably and does not generate rattling in a short period of time. Further, although the steering shaft support frame 24 supports the upper part of the golf bag, it does not hinder stable support of the steering shaft 6.

Further, in the illustrated golf car described above, one steering wheel 3
Since it is a three-wheeled vehicle provided with (front wheel) and two drive wheels 4, 4 (rear wheel) on the left and right, the structure of the body frame 1 tends to be unstable due to the left and right inclinations. Protruding frame parts 20a, 20a are provided on both sides, and these projecting frame parts 20a, 20a are connected to the outer center points FC, FC 'of the steering wheel 3 and the drive wheels.
Since the line segments L and L'connecting the outer center points RC and RC 'of 4 and 4 respectively on the same side of the vehicle body are made to project to the outside, it is possible to Even if there is, one of the projecting frame portions 20a, 20a does not come into contact with the vehicle body before reaching the overturning angle, and the vehicle body does not fall down.

In the above embodiment, the bar handle is used as the handle, but a circular handle may of course be used.

〔The invention's effect〕

As described above, in the standing-type golf car of the present invention, the structure of the steering shaft support frame has the rear frame portion inclined to the side opposite to the oblique direction of the steering shaft and the same direction as the steering shaft. Since the inclining front frame portion is integrally connected and fixed to each other, a large bending rigidity is exerted against a load in the front-rear direction. Therefore, even when the driver applies weight to the steering shaft in the front-rear direction when driving on a slope, the steering shaft can be stably supported for a long period of time. Even if the steering shaft support frame supports the upper portion of the golf bag, it does not make the steering shaft support unstable.
