Conventionally, the improvement technique regarding the passenger | crew step structure of a motorcycle is known (for example, refer patent document 1).
Japanese Utility Model Publication No. 61-6482 (Fig. 2)

  FIG. 2 of Patent Document 1 is a cross-sectional view of a motorcycle step, and the motorcycle step is directed to the periphery except for the inside of Step Body 1 (the symbol is the same as that of the same publication). The protruding protrusion 2 is provided, and the elastic body 3 is bonded or baked inside the protrusion 2. In normal times, the elastic body 3 supports the foot and prevents vibrations from being transmitted to the foot. In addition, when the occupant steps on the step, the elastic body 3 bends and the protruding edge 2 appears, and the protruding edge 2 bites into the shoe sole, mainly supporting the foot with the protruding edge 2 so that the tension can be applied. is there.

  However, in the step of Patent Document 1, since the protruding edge 2 does not have the elastic body 3, when the driving posture is taken such that the shoe sole is inclined on the step, the shoe sole comes into contact with the protruding edge 2 and vibration occurs. Absorption may be insufficient.

  Then, this invention makes it a subject to provide the step structure provided with sufficient vibration absorption performance irrespective of a driving posture.

In the invention according to claim 1, a protrusion is projected upward at a predetermined interval around the periphery of the step where the occupant puts his / her foot, and a vibration isolating member is provided on the step. In the step structure of the saddle-ride vehicle that is higher than the portion, the vibration isolating member includes a main body portion disposed on the inner side of the peripheral edge, an extension portion that extends outward from the main body portion and is disposed between the protrusions. consists, vibration isolating member is deflected when a predetermined load on the upper surface of the vibration isolation member such, the upper surface of the extending portion, at Rukoto such substantially equal to the upper surface of the lowered and projections, the passenger's feet in projection It is characterized by being configured to receive.

  In the invention which concerns on Claim 2, the height dimension of the extension part was set substantially the same as the height dimension of a protrusion.

  The invention according to claim 4 is characterized in that the extension part is provided with a hollow part.

  In the invention which concerns on Claim 5, the peripheral edge of the step was formed in the waveform by the side view.

In the invention according to claim 6, anti-vibration member is characterized in that detachably fastened via a fastening member to the step.

In the invention according to claim 1, the vibration isolating member includes a main body portion that covers the inside of the peripheral edge, and an extending portion that extends outward from the main body portion and covers between the protrusions. It is provided between the protrusions of the step.
In a normal time when the foot is placed horizontally on the step, the projection is hidden between the extension portions, so that the shoe sole is difficult to contact the projection. Further, when a predetermined load is applied to the upper surface of the vibration isolating member, the vibration isolating member bends, the upper surface of the extension part descends , becomes substantially the same as the upper surface of the projecting part, the shoe sole contacts the projecting part, and the projecting part Can receive the feet of the crew.

Further, even if the driving posture is such that the feet are inclined on the step, the extending portion that covers between the protruding portions is slightly extended outward, so that the protruding portion and the shoe sole are difficult to contact.
Therefore, even if the driving posture slightly changes, it is difficult to transmit vibration from the step to the foot, and there is an advantage that the driving comfort can be improved.

In the invention which concerns on Claim 2, the height dimension of the extension part is set to be substantially the same as the height dimension of the protrusion part, and when the load is applied to the shoe sole, the extension part descends, As it enters, the protrusion and the sole can come into contact.
Therefore, except when the occupant steps on and a load is applied to the step, the shoe sole is less likely to come into contact with the protrusion, and there is an advantage that the driving comfort can be improved.

  In the invention which concerns on Claim 3, the height dimension of the extension part is set larger than the height dimension of the protrusion part, and when the load is applied to the shoe sole, the extension part descends, and between the protrusion parts. enter. Then, the extending portion is bent by a predetermined load, and the protrusion and the shoe sole can come into contact with each other.

  Accordingly, the shoe sole is less likely to come into contact with the protrusion except when the occupant steps on and a predetermined load is applied to the step. Except when strung, it is possible to make it difficult for the shoe sole to come into contact with the protrusion, and it is difficult for vibration to be transmitted to the foot, so that there is an advantage that the driving comfort can be improved.

In the invention which concerns on Claim 4, since the hollow part was provided in the extension part, when extended, the extension part can be made thicker by making it easy to elastically deform the extension part.
By making the extension portion thicker, the upper surface of the vibration isolating member can be provided further above the protrusion, and the shoe sole can be made more difficult to contact the protrusion. In addition, there is an advantage that vibration can be easily absorbed by the hollow portion.

In the invention according to claim 5, since the peripheral edge of the step is formed in a waveform in a side view, the direction of the load applied to the extending portion of the vibration isolation member is shifted from the downward in the vertical direction of the vehicle body frame to the left and right in the width direction. Even in such a case, the extending portion is guided by the peripheral edge formed in a waveform.
Since the extending portion is guided by the peripheral edge formed in the waveform, there is an advantage that the extending portion can be easily deformed downward.

In the invention according to claim 6 , since the vibration isolating member is detachably fastened to the step via the fastening member, the vibration isolating member can be easily replaced.
Therefore, there is an advantage that the maintainability of the vibration isolating member can be improved.

Step 23 includes a step body 32 and a vibration isolating member 33 fitted to the step body 32 from above, and a fastening member 34 from below the vibration isolating member 33. Thus, the vibration isolation member 33 is fixed to the step body 32. The shoe soles of the occupant's feet do not necessarily contact the upper surface of the step body 32 horizontally, but may contact diagonally due to changes in the driving posture, so that the front surface 33a and the rear surface 33b of the vibration isolation member 33 are contacted. An extending portion 35 is provided so that the shoe sole does not directly contact the step body 32 even if the shoe sole of the occupant's foot is inclined.
The figure shows the step 23 on the left side, and the body frame 11 is omitted.

The step body 32 includes a bracket portion 42 having a mounting hole 41 for mounting on the vehicle body frame 11 (see FIG. 1), and a body main body 43 mounted on the bracket portion 42. Consists of. And, the upper part 44 of the body main body 43 is provided with a protrusion 47 composed of a groove 45... (... indicates a plurality, the same applies hereinafter) and a protrusion piece 46. The extension portions 35 of the vibration isolation member 33 are formed so as to fit into the grooves 45. When the vibration isolation member 33 is bent downward, the lower portions 51 of the extension portion 35 are projected. It shows receiving in the groove part 45 ... of the part 47. FIG.
Here, the lower part 51 is formed in a shape and a position that can be engaged with the peripheral edge 55 of the step while being formed in a waveform in a side view in the extension part 35 of the vibration isolation member. This means a portion that is supported by the peripheral edge 55 of the step when the upper surface thereof is lowered by receiving a load.

That is, when viewed from the side, the peripheral edge 55 of the step is formed in a waveform, and the lower part 51 of the vibration isolating member is formed in a waveform.

Since the lower part 51 ... of the extension part 35 is always located above the groove part 45 ... provided between the protrusion part 46 ... below the protrusion piece part 46 ..., the vibration isolating member Even when the direction of the load applied to the upper surface 52 of 33 is shifted from the downward in the vertical direction of the body frame to the left and right in the width direction, the lower portions 51. Guided by the grooves 45. Since the extending part 35 is guided by the peripheral edge 55 formed in a waveform, the extending part 35 can be easily deformed downward.

In addition, the lower part 51 of the vibration isolating member is formed in a corrugated shape in a side view, and is formed in a shape and a position where the corrugated unevenness of the lower part 51 and the corrugated unevenness of the peripheral edge 55 can mesh with each other. Thus, even when the direction of the load applied to the extension portion 35 of the vibration isolating member is shifted from the downward in the vertical direction of the body frame to the left and right in the width direction, the lower portion 51 formed in the waveform has the waveform of the peripheral edge 55. Guided, the lower part 51 fits around the peripheral edge 55.
Accordingly, by arranging the corrugated shape of the lower portion 51 so as to fit the corrugated shape of the peripheral edge 55, the extending portion 35 can be easily deformed when deforming downward .

The protrusion 47 appears between the two, and the protrusion 47 receives the occupant's foot. When the anti-vibration member 33 contacts the upper surface 52 but does not reach a predetermined load, the upper surface 52 of the extending portion 35 is located at a higher position than the projecting portion 47. Receive the feet. Details will be described with reference to FIG.

FIG. 4 is a view taken in the direction of arrow 4 in FIG. 3 and shows that the vibration isolating member 33 is attached to the peripheral edge 55 of the body body 43 having a substantially U-shape when viewed from the top.
The vibration isolating member 33 includes a main body portion 56 disposed on the inner side of the peripheral edge 55, and extending portions 35... Extending outward from the main body portion 56 and disposed between the protrusions 47.
Specifically, it can be said that the convex portion 53 provided on the upper surface 52 of the vibration isolating member 33 includes an extended portion 35 that extends outward from the inner surface 57 of the peripheral edge 55 by a length P.

FIG. 5 is a cross-sectional view taken along line 5-5 in FIG. 4, and a fastening plate 63 is inserted into an opening 62 provided in the holding portion 61 of the vibration isolator 33, and a support portion provided on the fastening plate 63 and the step body 32. It is shown that the vibration isolation member 33 is attached to the step body 32 by fastening 64 with the fastening member 34.
Accordingly, the vibration isolating member 33 is a member that can be detachably fastened to the step 23 via the fastening member 34.

Since the vibration isolating member 33 is detachably fastened to the step 23 via the fastening member 34, the vibration isolating member 33 can be easily replaced.
Therefore, the maintainability of the vibration isolating member 33 can be improved. The positioning member 65 is a member fixed to the fastening plate 63 in order to position the fastening plate 63 with respect to the vibration isolating member 33.

  6 is a cross-sectional view taken along line 6-6 of FIG. 3, and the main body portion 56 of the vibration isolating member 33 is fitted from the upper side to the inner periphery 55 of the step body 32, and the vibration isolating member 33 is fastened via the fastening plate 63. 34 shows that it tightens from below. The periphery 55 of the step body 32 supports the vibration isolating member 33, and a support portion 64 that fixes the main body portion 56 of the vibration isolating member 33 is stretched around the step body 32. 71 is a hollow portion provided on the side surface 72 of the convex portion 53... 73 is a main body hollow portion provided inside the main body portion 56.

  The hollow portion 71 and the main body hollow portion 73 are set to have predetermined shapes and cross-sectional areas so that the upper surface 52 is appropriately bent when a load is applied to the upper surface 52.

  FIG. 7 is an exploded perspective view of the step structure of the saddle-riding vehicle according to the present invention. The fastening plate 63 is inserted into and integrated with the opening 62 opened in the holding portion 61 of the vibration isolating member 33. The integrated vibration-proof member 33 is fitted from above to a support portion 64 that spans the peripheral edge 55 of the step body 32, and a screw hole 75 that is opened in the fastening plate 63 is aligned with a hole 74 that is formed in the support portion 64, Thus, it is shown that the fastening member 34 can be fastened and assembled.

The operation of the step structure of the saddle riding vehicle including the vibration isolating member, the step body, the fastening plate, and the fastening plate will be described below.
FIG. 8 is an operation diagram showing that the vibration-proof member enters between the bent protrusions under the load of the occupant's sole.
(A) shows a state in which the upper surface does not receive a load and the shoe sole does not come into contact with the convex portion 53 that becomes the upper surface 52 of the vibration isolating member 33. The groove 45 and the convex portion 53 provided in the protrusion 47 of the step body 32 are shown. A space 76 is provided between the lower portion 51 and a circular hollow portion 71 is provided on a side surface 72 of the convex portion 53.
(B) is a cross-sectional view taken along the line bb of (a), in which the convex portion 53 that becomes the upper surface 52 of the vibration isolating member 33 is arranged at a higher position than the protruding piece portion 46 of the step body 32. is there.

(C) shows a state in which the upper surface of the convex portion receives a predetermined load W, and the shoe sole 77 comes into contact with the convex portion 53 that becomes the upper surface 52 of the vibration isolating member 33, and the groove portion provided in the projecting portion 47 of the step body 32. The meat of the vibration-proof member 33 made of an elastic material is moved and buried in the space 76 provided between the lower portion 45 of the convex portion 53 and the circular hollow portion 71 provided on the side surface of the convex portion 53. Shows the state.

(D) is a dd line sectional view of (c), and shows the state where the upper surface of the convex part 53 bends and the shoe sole 77 contacts the protruding piece part 46. The convex portion 53 of the vibration isolating member 33 is bent downward, and the bent portion fills a space 76 provided between the groove portion 45 provided in the protruding portion 47 of the step body 32 and the lower portion 51 of the convex portion 53, It is deformed by filling 71 and projecting in the direction of the arrow p.

  As described above, the space for absorbing the bent portion of the convex portion 53 is provided in the hollow portion 71 opened on the side surface 72 of the protrusion 47 and the vibration isolation member 33 of the step body 32, so that the convex portion 53 is received when a load is received. When the load falls to a predetermined load W, the convex portion 53 can be made substantially equal to the height of the protruding piece portion 46.

  That is, the vibration isolating member 33 includes a main body portion 56 that covers the inner side of the peripheral edge 55, and an extension portion 35 that extends outward from the main body portion 56 and covers between the protrusions 47. Since the protrusion 47 is normally hidden between the extended portions 35 by providing the between the protrusions 47 in step 23, the shoe sole 77 is unlikely to contact the protrusion 47. Further, when a predetermined load W is applied to the upper surface 52 of the vibration isolating member 33, the vibration isolating member 33 bends, and a protrusion 47 appears between the upper surfaces 52 of the extending portions 35, so that the shoe sole contacts the protrusion 47. The protrusion 47 can receive the occupant's feet.

  In addition, since the extending portion 35 that covers the space between the protruding portions 47 is slightly extended outward, the extending portion 35 exists on the peripheral edge 55 even if the foot is inclined. It is difficult to make contact with the shoe sole 77.

A predetermined load is applied by the vibration isolation member 33 provided between the protrusions 47, and the shoe sole does not contact the protrusion until the vibration isolation member 33 is lowered by a predetermined amount or more with this load.
Further, even if the foot is inclined by the extending portion 35 extended to the outside of the peripheral edge 55, the shoe sole is difficult to contact the protrusion 47, and therefore vibration is not easily transmitted to the foot.
As a result, driving comfort can be improved.
Moreover, since the extension part 35 only extends outward slightly, the enlargement of step 23 can be prevented.

Furthermore, since the vibration isolator 33 is detachably fastened to the step 23 via the fastening member 34, the vibration isolator 33 can be easily replaced.
As a result, the maintainability of the vibration isolation member 33 can be improved.

  Returning to FIG. 6, the extension amount P of the extension portion 35 of the vibration isolation member 33 is small, and the thickness T with respect to the extension amount P is largely P << T. The base portion 81 is difficult to bend. For this reason, it is the main body portion 56 that is mainly provided with the main body hollow portion 73 at the lower portion when the predetermined load is applied. Therefore, even if the foot is inclined, it is difficult to bend downward in the shape of a bow with the base portion 81 of the extending portion 35 as a fulcrum.

FIG. 9 is a diagram for explaining that the height dimension of the extension part is made larger than the height dimension of the protrusion part, and a hollow part is provided in the extension part. It is larger than the height dimension B, and B <A.
Since the height A of the extension is set to be greater than the height B of the protrusion, the shoe sole is less likely to come into contact with the protrusion unless the occupant steps on and a predetermined load is applied to the step. This makes it difficult for vibration to be transmitted to the foot, so that the driving comfort can be improved while maintaining the operability of the vehicle.

In addition, the extending portion 35 is provided with a hollow portion 71.
Since the extension part 35 is provided with the hollow part 71, the extension part 35 can be made thicker by making the extension part 35 easily elastically deformed when stretched.

By making the extension part 35 thicker, the upper surface 52 of the vibration isolation member 33 can be provided further above the protrusion 47 and the shoe sole can be made more difficult to contact the protrusion 47. In addition, vibration can be easily absorbed by the hollow portion 71.
Further, providing the hollow portion 71 can reduce the weight of the vibration isolation member 33.

  In the present embodiment, the hollow portion 71 has a circular shape, but may be a square, a rectangle, an ellipse, an oval, a triangle, a polygon such as a hexagon, or the like. In addition, the size of the hollow portion 71 can be arbitrarily set.

FIG. 10 is a diagram showing another embodiment of FIG. 9, in which the height dimension of the extending portion is made larger than the height dimension of the projecting portion, and the side surface 72 of the convex portion 53 is not provided with a hollow portion.
Since the height A of the extension is set to be greater than the height B of the protrusion, the shoe sole is less likely to come into contact with the protrusion unless the occupant steps on and a predetermined load is applied to the step. This makes it difficult for vibration to be transmitted to the foot, so that the driving comfort can be improved while maintaining the operability of the vehicle.

FIG. 11 is a diagram for explaining that the height dimension of the extension part is substantially the same as the height dimension of the protrusion part.
The height C of the extending portion is substantially the same as the height D of the protrusion in a side view, that is, C = D. Since the height C of the extension is set to be substantially the same as the height D of the protrusion, when a predetermined load is applied to the shoe sole, the extension 35 descends and is interposed between the protrusions 47. As it enters, the projection and the sole contact.

Except when a predetermined load is applied to the step, the shoe sole hardly touches the protrusion.
Except when a predetermined load is applied, the shoe sole is unlikely to contact the protrusion, and vibrations are not easily transmitted to the foot, so that the driving comfort can be enhanced.

In addition to the structure, shape, and material of the vibration isolating member, the setting of the load at which the shoe sole comes into contact with the projecting piece 46 is determined by the height of the extension 35 and the height of the projection 47 that accommodates the extension 35. It can be set according to the balance with the height dimension. For example, when a predetermined load is applied to the shoe sole, the shoe sole can be formed only in such a manner that the shoe sole contacts the protrusion 47 or the shoe sole does not contact the protrusion 47 for the first time. is there. In this way, by changing the height dimension of the extension portion, the load setting at which the shoe sole contacts the protrusion 47 can be freely performed.

FIG. 12 is a view for explaining that the lower portion of the extending portion is disposed in contact with a groove portion provided at the periphery and an operation view thereof.
In (a), when the upper surface 52 of the vibration isolating member 33 is not subjected to a load, the lower portion 51 of the extending portion provided in the vibration isolating member 33 is formed in the groove 45 provided in the peripheral edge 55 (see FIG. 6) of the step 23. It shows that it arrange | positions so that it may contact | abut.

In (b), when the predetermined load W is received from the shoe sole 77, the upper surface of the vibration isolating member 33 is recessed, and the shoe sole 77 is in contact with the protruding piece 46 provided on the peripheral edge 55.
When the load W is not received, the spaces 82 and 82 between the vibration isolating member 33 and the step 23 disappear when the load W is applied. This is because the vibration isolation member 33 made of an elastic material moves to fill the spaces 82 and 82.

  Although the step structure of the present invention is applied to a motorcycle in the embodiment, it can also be applied to a tricycle, and can be applied to a general vehicle.

  The step structure of the saddle-riding vehicle of the present invention is suitable for a motorcycle.
