Description

[Detailed Description of the Invention] The present invention relates to a step for a two-wheeled vehicle such as a two-wheeled motor vehicle.

Generally, the step is attached to a bracket installed on the side of the vehicle.
It is constructed by extending a step arm, pivoting it so that it can be retracted, and integrally coupling a cushioning step rubber to the step arm.
As shown in the publication, the hollow part of the step rubber is fitted and fixed to the step arm, and a gap is created between the upper wall surface of the hollow part of the step rubber and the upper surface of the step arm to allow elastic deformation of the step rubber. In this case, the step rubber surrounds the step arm and its entire circumference, so the thickness of the step rubber in the vertical direction is thick. The amount of elastic deformation in the direction increases, and the stepping comfort of the step and, ultimately, the riding comfort deteriorates.

@Since the step rubber protrudes further outward than the longitudinal outer end of the step arm, there is a risk that the outer end of the step rubber will rub directly against the road surface when the vehicle turns, causing damage or deformation. There is.

If a stopper is specially provided on the step arm to prevent excessive deformation of the step rubber in order to alleviate the problem (2) above, the structure of the step becomes more complicated and the cost increases accordingly.

The present invention was proposed in view of the above, and aims to provide a step for two-wheeled vehicles with a simple structure that can eliminate all the problems of conventional ones. A step rubber having a hollow formed therein is placed on top of the outer end of the step arm in the longitudinal direction without protruding outward, and there is a vertical gap in the hollow between the step rubber and the upper wall surface of the hollow. A stopper plate is housed in the step arm, the step rubber, and the stopper plate are integrally coupled by a through bolt passing through them.

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.
A bracket 2 is attached to the step mounting part 1 on the side of the vehicle body of a two-wheeled vehicle.
is fixed to the bracket 2, and the base of a metal step arm 3 made of forged duralumin material is pivoted 4, and the step arm 3 rotates around its four pivot points as usual. It can be held in a substantially horizontal extended position and a substantially vertical retracted position.

As shown in FIG. 1, the step arm 3 is formed to have a concave shape in its vertical section, and a step rubber 6, which will be described later, is superimposed and installed in a recess 5 on the upper surface of the step arm 3.

In addition, the step arm 3 is provided with several bolt through holes 7 with gaps in its longitudinal direction, and a grounding member 8 is protruded downward from the outer surface of the tip of the step arm 3. The grounding member 8 is used to ground the vehicle body on the road surface when the vehicle body frame is tilted when the two-wheeled vehicle is turning, etc., so that the rider can sense the tilt angle of the vehicle body.

The step rubber 6 formed of wear-resistant rubber or the like is installed in an overlapping manner in the recess 5 on the upper surface of the step arm 3.
The upper surface of this step rubber 6 has an uneven part 9 for preventing slipping.
is formed.

A cavity 10 is formed inside the step rubber 6, and several through holes 11 communicating with the cavity 10 are bored at intervals in the longitudinal direction at the bottom thereof.

A stopper plate 12 is accommodated in the cavity 10,
This stopper plate 12 has C-shaped bent portions 13 formed at both ends thereof, and a row of positioning protrusions 15 each having a bolt insertion hole 14 formed in the longitudinal direction is provided in the center thereof. A nut 16 is welded to the inside.

A gap C in the vertical direction is formed between the top surface of the stopper plate 12 and the top wall surface 17 of the cavity 10 of the step rubber 6, and the dimensions of this gap C and the position and size of the cavity 10 itself are as follows. This is an important factor in determining the spring resistance of the step rubber 6, and therefore, by appropriately selecting the cause of warpage, the spring characteristics of the step rubber 6 can be set relatively freely.

The step rubber 6, which has been set to a desired spring constant, is elastically deformed when a load is applied to its upper portion, thereby providing a good cushioning effect.

Further, the positioning protrusion 15 is fitted into the through hole 11 and fixed at a predetermined position within the cavity 10 of the stopper plate 12.

The bolt 1 is inserted from below the step arm 3 into the bolt through hole 7 and the bolt insertion hole 14 of the positioning protrusion 15.
8 and screwing this through bolt 18 onto the nut 16, the step arm 3 and the step rubber 6 can be firmly and integrally connected.

As described above, according to the present invention, the step arm 3 is extended from the step bracket 2 provided on the side of the vehicle body of the two-wheeled vehicle.
In the step for a two-wheeled vehicle that is retractably supported by a shaft 4, a step rubber 6 having a cavity 10 formed inside thereof protrudes outward from an outer end in the longitudinal direction of the step arm 3 on the upper surface of the step arm 3. A stopper plate 12 is accommodated in the cavity 10 with a gap C in the vertical direction between it and the upper wall surface 17 of the cavity 10, and the step arm 3, step rubber 6, and stopper Since the plates 12 are joined together by through bolts 18 passing through them, the size and position of the cavity 10 in the step rubber 6, as well as the upper wall surface 17 of the cavity 10,
The spring characteristics of the step rubber 6 can be set relatively freely by simply selecting the dimensions of the vertical gap C between the stopper plate 12 and the step arm 3. Vibrations can be effectively damped to provide excellent vibration-proofing properties, making it possible to improve the comfort of stepping.

Moreover, the step rubber 6 is attached to the step arm 3 with 1 bolt.
The stopper plate 12, which functions as a retainer when tightening the step rubber 6, can also be used as a stopper to prevent excessive deformation of the step rubber 6, which alone simplifies the structure and contributes to cost reduction.

In particular, since the step rubber 6 is superimposed on the upper surface of the step arm 3 and does not surround the outer periphery of the step arm 3, the special provision of the cavity 10 may cause damage to the step rubber 6 itself. The thickness in the vertical direction can be made relatively thin, and thus, together with the deformation prevention effect of the stopper plate 12 on the step rubber 6, the amount of elastic deformation of the step rubber 6 in the longitudinal direction or the lateral direction of the vehicle body can be reduced as much as possible. This allows for even better stepping comfort.

Further, since the step rubber 6 has its lower surface covered by the step arm 3 and does not protrude outward from the longitudinal outer end of the step arm 3, the outer end of the step arm 3 is strong against the road surface when the vehicle turns. Even if it is rubbed, there is no worry that the step rubber 6 itself will be rubbed against the road surface or directly receive a stronger impact from the road surface, and the step rubber 6 can be prevented from being damaged or deformed and its durability can be increased. , and can maintain its appearance in good condition for a long period of time.
