Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) This invention relates to a footrest for a saddle type vehicle that travels on rough terrain.

(Prior Art) Conventionally, straddle-type vehicles that travel on so-called uneven terrain such as vast wastelands, sandy areas, or grasslands have been equipped with front and rear wheels equipped with tires called balloon tires, as shown in the eighth factor. ,2
These wheels 1 and 2 are covered by fenders 3 and 4 to prevent mud from splashing when driving on rough terrain.

At the upper part of the fenders 3 and 4, especially the rear fender 4, there is a seat 5 for a rider extending from the front of the vehicle to the rear.
is installed, and the output of the engine 7 is controlled by operating a handle 6 located in front of the seat 5.
It runs well. In this case, in consideration of the stability of the rider's posture while straddling the seat 5, a footrest 9 is attached to the lower center of the frame 8 on which the front and rear wheels 1 and 2 are attached.
This contributes to the stability of maneuvering.

As shown in FIG. 9, this footrest 9 is constructed by fixing a bracket 10 to the vehicle body frame 8 by bolting or welding, and fixing a footrest leg 9A to this bracket 10 by welding or the like. The two-rest leg 9A is made of lightweight steel and has a so-called portal shape.

(Problem to be Solved by the Invention) However, in the conventional footrest 9 as described above, the tool 1 to the rest leg base 9A on which the rider's feet are placed are fixed to the bracket 1o by welding or the like. Since the bracket 9 is directly fixed to the frame 8 with bolts, the engine 7 etc.
This could easily be transmitted to the rest 9, and could cause discomfort to the rider.

This invention was made in consideration of the above facts,
To provide a comfortable 7-1-rest for a straddle-type vehicle that does not transmit vibrations from an engine or the like to a rider.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a hood rest for a saddle type vehicle in which a footrest leg base is attached to the lower part of the body frame of the saddle type vehicle via a bracket.
~ is equipped with a vibration absorbing part, and the above bracket is attached to this]
It is fixed to the vehicle body frame via the turbulence absorbing part.

(Function) Therefore, 7-Tress 1 of the saddle type vehicle according to the present invention
According to the publication, the vibrations of the vehicle body frame vibrated by the engine are absorbed by the vibration absorbing portion and are reduced and eliminated, so that the two-one-less one-less footrests do not vibrate and do not cause discomfort to the rider.

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

FIG. 4 shows the two-one-less saddle riding type vehicle according to the present invention! ~
1 is a side view showing a straddle-type four-wheeled vehicle to which one embodiment of the present invention is applied.

1) Four wheels 12 are mounted in front of the vehicle body frame 11.
This front wheel 12 is steered by a steering wheel 13. Further, a hanging wheel 14 is provided at the rear of the vehicle body frame 11, and this rear wheel 14 is rotationally driven by an engine 15 mounted in the center of the vehicle body. Furthermore, body frame 1
A seat 16 is attached to the rear upper part of the vehicle body frame 11, and a footrest 17 is provided at the lower center of the vehicle body frame 11.

FIG. 5 is a perspective view showing the vehicle body frame 11.

The vehicle body frame 11 is constructed by forming metal tubes into desired shapes for each section and connecting these metal tubes. Welding means are primarily used for connection. In FIG. 5, a main vibe 18 is provided at the upper center of the vehicle body, and a pair of down tubes 19 extending forward and diagonally downward are connected to the front part of the main vibe 18. On the other hand, at the rear of the main vibe 18, there is a pair of body tubes 2 extending downward.
0 is connected. This body duplex 2o is curved at the lower part of the vehicle body, becomes an outer tube 21, extends toward the front of the vehicle body, and is connected to the down tube 19.

The front wheel 12 is supported by one down tube and the lower tube 21 on the vehicle body frame 11#J side.

In addition, the main bracket 18A is attached to the down duplex 19.
is fixed, a head pipe (not shown) is provided on this main bracket 18A, and a steering mechanism is attached to this head pipe. 71- (not shown) is inserted. A handlebar 13 is attached to the upper end of this steering shaft, and a front wheel 12 is connected to the lower end thereof. Further, an engine 15 is mounted in a portion surrounded by the body tube 2o and the lower tube 21.

A seat pillar bracket 1-22 that engages the seat 16 is fixed to the main vibe 18. Also, Bodev”−
A pair of seat rails 23 extending diagonally in the -V direction are connected to 120 , and the seat rails 23 are reinforced by seat pillars 24 .

Further, the rear pant portions of the pair of seat rails 23 are connected by a guide plate 25.

A pair of footrests J7 are attached to the rear part of the mouth 7 chuzo 21, and are provided so as to respectively protrude outward. Each footrest 17 is connected by a connecting bridge 26. This footrest footrest leg base 27 and bracket 28 are constructed as a single piece.

The footless l-pedestal 27 is made of pumice steel or the like in a gate shape, and one end is gently curved up and the other end is made of pumice steel or the like.
It is fixed at 8. This bracket 28 is made by overlapping two flat plates, and one connecting bridge 26 is attached to the center. This connecting bridge 26 extends to the center of the portal-shaped footrest leg base 27 to ensure the strength of the footrest 17.

A vibration absorber 29 is provided on the bracket 28 . As shown in FIG. 3, these two initial storage parts include an inner sleeve 30, an outer sleeve 31, and an elastic body such as a rubber bush 32 mounted between these sleeves. The outer sleeve 31 is fixed to the arrangement 1-28 at Ifl, and the bolt 33 shown in FIG.
1 is inserted.

Moreover, the inner sleeve 30 is formed longer than the outer sleeve 31.

On the other hand, as shown in FIG. 7, a pair of mounting bases 34 are welded to the lower arm 1-121. Mounting surface 3 of this mounting base 34
A mounting hole 36 is formed in the mounting hole 34, and the mounting surface 35 is fixed to the vehicle so that the mounting surface 35 is horizontal to the vehicle. As shown in FIG. 6, the bracket 28 of the footrest 17 is made by attaching TiW poles 1-33 to the inner sleeve 30 of the vibration absorber 29 and the mounting holes 36 of the mounting base 34, and attaching them to the bolts 33 on the back of the mounting base 34. It is fixed to the lower tube 21 by fitting the nut 37. Two millless 1~
17, since the inner sleeve 30 is longer than the outer sleeve 31, only both end surfaces of the inner sleeve 30 come into contact with the washer 38 and the mounting base 34.

Therefore, as described above, the arrangement 1-28 of the footrest 17 is transmitted to the lower J-121 through the vibration absorbing section 29.
When the lower tube 21 vibrates due to the engine 15, the mounting base 34 and the inner sleeve 30 of the vibration absorbing section 29 vibrate, but this vibration is absorbed by the rubber bushing 32, damped, and moisture is removed. do. As a result, the vibrations are not transmitted to the outer sleeve 31 and the bracket 28, and in turn, the vibrations are not transmitted to the footrest leg base 27, so that the tools 1 to 1.
Responsiveness 1 - The rider who places his or her feet on the platform 27 does not feel uncomfortable.

In the above embodiment, the straddle type vehicle has two front wheels and two rear wheels.
Although the vehicle has been described as a four-wheeled vehicle, it may be a three-wheeled vehicle with one front wheel and two rear wheels.

〔Effect of the invention〕

As described above, since the bracket to which the footrest of the straddle-type vehicle according to the present invention is attached is fixed to the vehicle body frame via the vibration absorbing section, the vibration of the vehicle body frame vibrated by the engine can be absorbed by the vibration absorbing section. Since it can be damped, the footrest legrest will not vibrate and will not cause discomfort to the rider.
