Abstract

PURPOSE:To enable an accelerating operation by stepping action and to reduce handle mainpulations, by installing an accelerator pedal on a foot board. CONSTITUTION:A sliding component 32 connected with a throttle valve of a carburetor is installed movably in a longitudinal direction by giving a necessary stroke on the front part of one side of a foot board 12, also an accelerator pedal 31 is installed turnably in a longitudinal direction on the foot board 12 at the rear of an installing position of the sliding component, the accelerator pedal 31 and the sliding component are connected by a linking component with each other, a spring 35 which bounces the sliding component 32 toward its rearward stroke end is installed on either the sliding component 32 or the accelerator pedal 31 and an opening of the throttle valve is adjusted by a movement of the sliding component 32 corresponding to pushing in quantity of the accelerator pedal. An accelerating operation, therefore, can be done by a pushing in operation of the accelerator pedal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accelerator pedal assembly structure for a scooter type motorcycle.

Conventionally, in scooter-type motorcycles, like other motorcycles, the throttle opening degree has been adjusted by rotating an accelerator grip provided on the handlebar. For this reason, if careless force is applied to the hand gripping the steering wheel while the vehicle is running, there is a risk that the accelerator grip will rotate unexpectedly, and beginners in particular may want to be free from operating the accelerator with the steering wheel. there were.

SUMMARY OF THE INVENTION An object of the present invention is to attach an accelerator pedal to the footboard of a scooter-type motorcycle so that the accelerator can be operated by stepping on the foot, thereby freeing the operator from operating the accelerator at the bottom of the handle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a scooter in which the present invention is implemented and an accelerator pedal is assembled. In the vehicle body of this scooter, a footboard 12 is formed at the lower front part of the seat 11, and a leg shield 18 is attached to the front part of the footboard 12 in an upright state.

As shown in FIGS. 8 to 5, an opening 12B extending in the front-rear direction is formed in the front right side of the footboard 12, and a sliding member to be described later is accommodated in a peripheral recess of this opening 12&. A box body 21 is suspended and bolted to the footboard 12 together with a lid body 22. Lid body 2
2 is provided with a slit-shaped elongated hole 22a facing the opening of the box body 21 at its substantially central portion. The slit-like long hole 22B extends a required length in the front-rear direction, and the accelerator pedal 31 is connected to the footboard 1 at the rear of the slit-like long hole 22a.
2 so that it can rotate five times in the front and rear directions.

Further, a large number of rollers 28 rotatably supported on both side walls are housed in the bottom of the box body 21, and a sliding member 32 is housed on the rollers 23. The sliding member 32 consists of an angular main body part 82a and a head part 820 that is integrated with the main body part 82a through a spigot part 82b. Suspended from the lid body 22,
It is housed in a box 21. An operation wire 88 connected to a throttle lever connected to a throttle valve of a carburetor (not shown) is connected to the rear protrusion 82d of the sliding member 32, and the sliding member 82 is connected to the rear wall of the box body 21. The throttle valve is closed when it is in contact with the slide member 82, that is, when it is at the rear stroke end, and opens as the sliding member 82 moves forward.

The sliding member 82 and the accelerator pedal 81 are connected by a rod 84 that is a link member. Both ends of the rod 84 are spherical, and the upper end of the rod 84 is rotatably attached to the upper front surface of the accelerator pedal 81.
4 is rotatably attached to the head 828 of the sliding member 82.

Moreover, the sliding member 82 is connected to the front wall of the box body 21.
is urged backward by a compression spring 85 interposed between the front surfaces of the sliding member 82, and comes into contact with the rear wall of the box body 21 via the cushion material 82e fixed to the rear surface of the sliding member 82, and is located at the rear stroke end. There is. The accelerator pedal 81 is held in a predetermined forward tilted state as shown in FIG. 1 when the sliding member 82 is located at the rearward stroke end.

In the scooter with the accelerator pedal 81 assembled in this manner, when the driver depresses the accelerator pedal 81 forward, the sliding member 32 moves against the compression spring 85 and moves onto the roller 23 according to the amount of the accelerator pedal 31 being depressed. move forward. Therefore, the operating wire 33 is pulled forward by the sliding member 82 and the throttle valve opens according to the amount of movement of the sliding member 82, and the throttle opening degree is arbitrarily adjusted by pressing the accelerator pedal 81. Further, when the -5 accelerator pedal 31 is released, the sliding member 32 moves rearward due to the biasing force of the compression spring 85 and reaches the rear stroke end. Therefore, the operating wire 33 is pulled back and the throttle knob is closed, and the accelerator pedal 81 is rotated rearward to return to the predetermined forward tilted state.

Therefore, in the scooter of this embodiment, the accelerator operation can be performed extremely smoothly by pressing the accelerator pedal 31, and the driver can be relieved from the accelerator operation using the steering wheel. In addition, in this scooter, the accelerator pedal 81 and the sliding member 82 are connected by a rod 84, and the sliding member 82 is connected to the compression spring 82.
Since the means for biasing the accelerator pedal 81 toward the rear stroke end by the accelerator pedal 81 is adopted, the assembly structure of the accelerator pedal 81 does not become complicated.

Note that this embodiment shows one embodiment of the present invention, and if a material with low sliding resistance is used as the sliding member 82, the large number of rollers 28 can be omitted. Furthermore, if a sliding member 82 that is fitted into the long slit 22B and slides on both side edges of the long slit 22B is used, the box 21, the rollers 28, etc. can be omitted. In this case, a spring may be interposed between the footboard 12 and the accelerator pedal 81.

Further, although this embodiment has been described with reference to an example in which the present invention is applied to a scooter, the present invention is not limited to scooters, but can be applied to various types of scooter-type motorcycles having a footboard on the body.

As explained above, in the present invention, the sliding member connected to the throttle valve of the carburetor is attached to the front part of one side of the foot port so as to be movable in the front and back direction with a required stroke, and the sliding member is The accelerator pedal is attached to the footboard so as to be rotatable in the front-rear direction at the rear of the member assembly position, the accelerator pedal and the sliding member are connected by a link member, and the sliding member is biased toward the rear stroke end. A spring member is attached to a sliding member or an accelerator pedal, and the opening degree of the throttle valve is adjusted by moving the sliding member in accordance with the amount of depression of the accelerator pedal. Therefore, according to the present invention, the accelerator can be operated by depressing the accelerator pedal, thereby freeing the driver from operating the accelerator on the handlebar, and the accelerator can be operated without a complicated assembly structure. The pedals can be attached to the footboard.
