Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a footrest device for a nuclear vehicle.

(Prior Art) In a four-wheel straddle-type vehicle, footrests are normally provided protruding from both sides of the lower part of the vehicle body frame, and a rear fender that covers the rear wheels is provided behind each footrest. A rider straddling the seat operates the vehicle with his feet resting on the footrest.

By the way, in this type of vehicle, the front lower end of the rear fender is extended to the vicinity of the footrest, and this extension is used as an auxiliary footrest so that the foot on the footrest can be moved rearward in four directions. , it has been proposed that this auxiliary footrest increases the degree of freedom in the footrest position (for example, Utility Model Application No. 58-1327
Publication No. 90).

(Problems to be Solved by the Invention) By the way, the rear fender is for covering the rear wheel and has a large area. For this reason, when the rear fender is extended as described above, air resistance increases during driving, which is particularly undesirable for sports vehicles such as those described above.

Further, since the rear fender usually does not have sufficient strength, it is not preferable in terms of strength to use the extension of the rear fender as an auxiliary footrest.

Furthermore, since the -L side of the auxiliary footrest is easily soiled by contact with feet, it is desirable to replace it with a new one after using the auxiliary footrest for a certain amount of time. However, in the conventional configuration, since the auxiliary footrest is integrally molded with the supporter fender, it is necessary to perform the replacement together with the supporter fender, and therefore, such replacement is not easy in terms of workability and cost.

(Purpose of the Invention) This invention was made in view of the above-mentioned circumstances, and has a sufficient function as an auxiliary footrest, and is designed to prevent the air resistance of the vehicle body from increasing even when it is used in this way. At the same time, the purpose is to enable easy replacement of the auxiliary footrest.

(Structure of the Invention) To achieve the above object, the present invention is characterized by a saddle-riding type in which footrests are provided protruding from both sides of the lower part of the vehicle body frame, and an auxiliary footrest is adjacent to the rear of each footrest. In the vehicle, the rear part of the -F auxiliary footrest is bent upward, and the auxiliary footrest is detachably attached to the vehicle body frame.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

An engine 18 is disposed inside the small frame 2. This engine 18 is rigidly attached to the vehicle body frame 2 and drives the rear wheels 14. 1111 The front part of each seven-part frame 3 supports a fuel tank 19,
The rear part of the vehicle body frame 3 and the seat rail 8 support the seat 20. Additionally, a pair of left and right footrests 22 are provided on which the rider straddling the seat 20 rests his or her feet 21.
22 are provided. Each of the footrests 22 is made of sheet metal, and has a rectangular shape long in the left-right direction when viewed from the rt plane, one end of which is attached to the outside of the lower frame 4.
The other end projects outward.

A resin fender 25 is provided to cover the soil surface and the rear of each of the front wheels 11, and a resin fender 26 is provided to cover the upper surface and front surface of each rear wheel 14.
are provided respectively. These Fun[] Fender 2
The rear fender 26 is provided at a position sandwiching the footrest 22 from the front and rear, and the front lower end 27 of the rear fender 26 is located at a higher position than the footrest 22.

In FIGS. 1 to 4, an auxiliary footrest 28 is adjacent to the rear of each of the footrests 22. As shown in FIGS. The auxiliary footrest 28 is formed by combining circular metal vibrators, and has a main vibrator 29 that is bent into a U-shape when viewed from above. This main vibe 29 includes front and rear pipes 29a and 29b extending in the left-right direction, and a side vibe 2 that connects the outer ends of these two vibes 29a and 29b.
It is composed of 9C. The moe vibe 29a is provided along the footrest 22 on the rear side of the footrest 22, and its inner end is screwed to the rear lower end of the upper frame 3 with a bolt 30. Further, the side vibrator 29c has a rear convex shape, and the inner end of the rear pipe 29b connected thereto is screwed to the front and rear midway portions of the backstay 9 with bolts 31.

Further, outer connecting vibes 33 and 34 are provided to connect the left and right middle portions of the front vibe 29a and the rear pipe 29b. Each of these vibrators 33 and 34 are formed by bending them into a circular shape when viewed from the side.
The rear side of the outer connecting vibe 34 is located further rearward than the side vibe 29c, and the rear side of the inner connecting vibe 33 is located further rearward than the rear side of the outer connecting vibe 34.

Therefore, the foot 21 on the footrest 22 can be moved up to the auxiliary footrest 28, which increases the degree of freedom in the footrest position. In addition, the auxiliary footrest 28
Its rear part is bent upward, which improves its rigidity.

Furthermore, the rear part of the auxiliary footrest 28 is shaped to surround the rear outer surface of the leg 21 together with the backstay 9. In addition, 36 is a cross member.

On the other hand, the front lower end 27 of the paddle fender 26 is screwed to the upper part of the side vibrator 29c and the inner connecting vibrator 33 with bolts 35, respectively. That is, the rear fender 26, which has relatively low rigidity, is strongly reinforced by the auxiliary footrest 28, and therefore, the rear fender 26 is prevented from flapping during driving.

In the above case, the auxiliary footrest 28 can be detachably removed from the vehicle body frame 2 or rear fender 26 by loosening each bolt 30, 31, 35.
In other words, this auxiliary footrest 28 can be replaced with another new one.

On the other hand, the starting device for the engine 18 is a kick type, and a kick pedal 38 is provided for this purpose.

The kick pedal 38 has an arm 41 that is pivotally supported on the right side of a rotating case 39 connected to the engine 18 so as to be movable up and down on a horizontal shaft 40, and a pedal body 43 is attached to the projecting end of the arm 41 by a vertical shaft 42. is pivoted so that it can rotate left and right. The upper end of this pedal body 43 is bent forward, and this serves as a foot pedal part 43a.

When the kick pedal 38 is to be depressed and operated when the engine 18 is started, the foot pedal 43a should first protrude to the right as shown by the chain double-dashed line and the arrow A in each figure. Rotate the pedal body 43 around the vertical coaxial shaft 42 and place your foot on the foot pedal 4a.Next, as shown by the dotted chain line and the arrow 13 in each figure, the kick pedal 3 is rotated.
8 (depress it) and rotate this kick pedal 38 backward and downward around the horizontal axis 40.Then, the engine 18 will start in conjunction with this.

Further, in this case, when the foot is removed from the first foot pedal 43a, the kick pedal 38 is returned to the position indicated by the chain double-dashed line in each figure by the biasing force of a spring (not shown). During running, the pedal body 43 is rotated until the foot 43a is at the position indicated by the solid line in each figure so that the foot 43a does not get in the way.

By the way, when the pedal main body 43 is depressed as described above, if the foot 43a or the foot comes into contact with the auxiliary footrest 28, this operation will be hindered. Therefore, in this embodiment, the inner and outer connecting vibes 33 and 34 are
The rear side of the side vibrator 29c is moved back more than the side vibrator 29c.
F. This is to prevent contact from occurring. Further, in order to prevent the above-mentioned contact with the front lower end 27 of the rear fender 26, the front lower end 27 is formed so that its front surface has four sides 45.

Note that 5 or more depends on the example shown in the figure, but the auxiliary footrest 28
may be made of sheet metal, and the material may be the metals mentioned above,
It may be made of resin, and the front lower end 27 of the rear fender 26 does not need to be screwed to the auxiliary footrest 28.

(Second example) 5 to 7 show a second embodiment.

Since this embodiment has almost the same configuration as the previous embodiment, only the different configurations will be explained and the common configurations will be explained.

Reference numerals are given to the drawings and their explanations are omitted.

In this embodiment, the main vibe 29 of the auxiliary footrest 28 does not have a front pipe 29a, and the front end of the side vibe 29c is detachably screwed to the protruding end of the footrest 22 with a bolt 47. In addition, the inner connecting vibe 33
The front end of the -L is bent outward, and the bent end is welded to the side vibrator 29e, and the front end of the outer connecting vibe 34 is welded to the bent portion of the -L inner connecting vibe 33. . On the other hand, the front lower end 27 of the rear fender 26 is not screwed to the auxiliary footrest 28.

In this embodiment, the front lower end of the rear fender 26 may be detachably screwed to the auxiliary footrest 28.

(Effects of the Invention) According to the present invention, since the rear part of the auxiliary footrest is bent in the - direction, the rigidity of the auxiliary footrest is improved compared to a case where the auxiliary footrest is simply formed flat. Become. Moreover, since the auxiliary footrest is attached to the heavy body frame with high rigidity, sufficient rigidity can be ensured in the auxiliary footrest.

Furthermore, since the front end of the rear fender is not extended as in the conventional case, the air resistance of the vehicle body is prevented from increasing and the rigidity can be improved as described above.

Moreover, since the auxiliary footrest is detachable from the vehicle body frame, if it becomes soiled, only the auxiliary footrest can be replaced with a new one. Therefore, compared to the conventional case where it was necessary to replace the entire rear end, this replacement can be easily performed.
