  FIG. 3 is a side sectional view showing the wind screen 51 and the rail 61 together with the peripheral structure, and FIG. 4 is a view showing the side sectional structure of the rail 61. The rails 61 and 61 and the sliders 71 and 71 are members constituting the main part of the moving mechanism 60 that moves the wind screen 51. As shown in FIGS. 3 and 4, the sliders 71 and 71 are the rails 61 and 61, respectively. By moving up and down while being guided, the wind screen 51 is moved from the lower limit position L0 to the upper limit position H0 shown in FIG. Further, the rails 61, 61 are arranged so as to incline rearwardly of the vehicle body, and are formed in a bow shape in which the inclination angle approaches substantially vertical as going upward, so that the wind screen 51 has the inclination angle. Move up and down while changing. In this embodiment, the moving mechanism 60 is formed in a manual type in which a user (driver or the like) moves the wind screen 51 by hand.

The rails 61 and 61 and the sliders 71 and 71 have a bilaterally symmetric structure, and only one rail 61 and the slider 71 will be described below. 5 is an exploded perspective view of the rail 61, FIG. 6 is a sectional view taken along line VI-VI in FIG. 4, and FIG. 7 is a sectional view taken along line VII-VII in FIG.
As shown in FIG. 5, the rail 61 includes a pair of left and right left rail halves 62L and a right rail half 62R formed of a metal material or a resin material. The left rail half body 62L and the right rail half body 62R have a substantially bilaterally symmetric shape. As shown in FIGS. 5 to 7, rail portions 63L, 63R having a substantially U-shaped cross section, and the rail portions 63L, A plurality of (in this example, five) concave portions 80 (see FIG. 4) formed at intervals in the rail longitudinal direction below 63R, and rail portions 63L and 63R and a base end portion 64L extending from the concave portion 80, Integrated with 64R. Sliding plates 65 and 65 are respectively disposed in the rail portions 63L and 63R of the left rail half 62L and the right rail half 62R, and the slider 71 is disposed between the left rail half 62L and the right rail half 62R. It is caught. The base end portions 64L and 64R are fastened with bolts 66 and nuts 67 in a state of being overlapped with each other, whereby the rail 61 is assembled. The sliding plate 65 is formed of a plate member such as a stainless material or an aluminum material, and forms a sliding surface with a low friction coefficient.

As shown in FIG. 5, the slider 71 includes a slider body 72 that is substantially L-shaped in side view. The slider main body 72 has a base end portion 72A inserted between the rail portions 63L and 63R, and an extension portion 72B extending from the base end portion 72A. Screw holes 73 and 73 through which screws 54 for connecting the connecting plate 53 shown in FIG. 3 are passed are formed at the upper end of the extension 72B.
In addition, the base end portion 72A is integrally provided with first protrusions 76 and 76 and second protrusions 77 and 77 protruding in the left-right direction with a space in the front-rear direction. Here, resin caps 75 and 75 formed of a low friction material are fitted to the first protrusions 76 and 76. As shown in FIG. 6, the first protrusions 76 and 76 fitted with the resin cap 75 are formed to have substantially the same size as the gap between the rail portions 63L and 63R, and engage with the rail portions 63L and 63R. It is guided along the longitudinal direction of 61. In this case, since the resin caps 75 and 75 move while contacting the low friction coefficient sliding plates 65 and 65 in the rail portions 63L and 63R, the slider 71 can be moved smoothly.

  Further, the second protrusions 77 and 77 are formed as protrusions having a smaller diameter than the first protrusions 76 and 76 and having a left and right protrusion amount shorter than that of the first protrusions 76 and 76. As shown in FIG. It is formed in the shape of a protrusion that can freely move back and forth in the recess 80 formed in the above. That is, when the slider 71 is mounted on the rail 61, as shown in FIG. 5, the relatively large-diameter first protrusions 76 and 76 inserted between the rail portions 63L and 63R are provided at the lower end of the base end portion 72A. The second protrusions 77 and 77 having a relatively small diameter and short diameter that can be moved forward and backward in the recess 80 are provided at the lower end position of the base end portion 72A.

Next, the recess 80 of the rail 61 will be described in detail. As shown in FIG. 4, the concave portion 80 is formed in a concave shape that is recessed rearward and obliquely downward by being recessed in a substantially vertical direction with respect to the axis L <b> 1 extending along the inclination of the rail 61. 7, the left rail half body 62L and the right rail half body 62R have a bilaterally symmetric shape. As shown in FIG. 7, the concave portion 80 will be described below with reference to the left rail half body 62L shown in FIG. 80 will be described.
As shown in FIGS. 5 and 7, the recess 80 extends in the left-right direction of the rail 61, and the second protrusions 77, 77 of the slider 71 have openings 81 formed on the bottom surfaces 63 </ b> A of the rail portions 63 </ b> L, 63 </ b> R. Left and right first recesses 82, 82 that can be fitted via 81 are provided, and a slider 71 between the second projections 77, 77 is inserted into the first recesses 82, 82 so that the second projections 77, 77 can be inserted. Escape portions 84 and 84 for escaping the portion are provided.

The openings 81 and 81 are formed in an opening shape that allows the second protrusions 77 and 77 to pass therethrough but does not allow the first protrusions 76 and 76 that are wider than the second protrusions 77 and 77 and have a larger diameter. As shown in FIG. 5, the sliding plates 65 and 65 also have openings 65 </ b> A and 65 </ b> A in portions overlapping the openings 81 and 81, and the first recesses 81 and 81 of the second protrusions 77 and 77. It is configured so as not to prevent insertion.
The relief portions 84, 84 are substantially vertical from the bottom surfaces 84A, 84A continuous to the bottom surface of the first recess 81, the lower inclined surfaces 84B, 84B continuous below the bottom surfaces 84A, 84A, and the upper ends of the bottom surfaces 84A, 84A. The lower inclined surfaces 84B and 84B are inclined along the bottom surface of the base end portion 72A of the slider 71 when the second protrusions 77 and 77 of the slider 71 are placed in the first recess 81. Formed on the surface.

  As shown in FIGS. 5 and 7, the first recess 81 has a pair of left and right locking pieces 90, 90 on which the second protrusions 77, 77 fitted to the first recesses 82, 82 can be locked. Be placed. The second protrusions 77 and 77 are fitted into the first recesses 82 and 82 with a slight gap between them and the first recesses 82 and 82, and the locking pieces 90 and 90 are inserted into the gaps. Has been placed. As shown in FIG. 5, the locking piece 90 is formed by bending a leaf spring material. The U-shaped bent portion 91 is bent in a substantially U-shape, and both ends of the U-shaped bent portion 91 are inward. A pair of bent portions 92, 92 are provided. As shown in FIG. 8, the U-shaped bent portion 91 of the locking piece 90 fits into the first recess 82 and is held in the first recess 82. In this case, the pair of bent portions 92, 92 of the locking piece 90 are arranged with a gap in the substantially vertical direction, and the second protrusion 77 inserted in the first recess 81 is sandwiched and locked from above and below.

  In this configuration, as shown in FIG. 4, the second projections 77 and 77 are recessed by tilting the slider 71 clockwise in FIG. 4 (rear side of the vehicle body) with the first projections 76 and 76 as fulcrums. 80 can be inserted. For example, when the user (driver or the like) holds the wind screen 51 connected to the slider 71 with his hand and tilts it to the rear side, the slider 71 is rotated clockwise with the first protrusions 76 and 76 as fulcrums. The second protrusions 77 and 77 can be inserted into the recess 80 by an easy operation. In addition, this operation uses the first protrusions 76 and 76 as fulcrums, the operation portion (for example, the upper part) of the wind screen 51 as a power point, and the engaging portion between the second protrusion 77 and the locking piece 90 as an action point. Since the “lever principle” is used, it is possible to amplify the user's operating force and engage the second protrusions 77, 77 of the slider 71 with the locking pieces 90, 90.

In this case, as shown in FIG. 8, since the concave portion 80 of the rail 61 is provided in the vehicle body rearward direction of the rail 61, when the second protrusions 77 and 77 of the slider 71 are inserted into the concave portion 80, the slider 71 and the wind screen. 51's own weight (indicated by symbol F in FIG. 8) acts on the recess 80. For this reason, the concave portion 80 prevents the slider 71 and the wind screen 51 from falling down the rail 61.
In addition, since the locking pieces 90 and 90 that are locked to the second protrusion 76 of the slider 71 are disposed in the recess 80, the second protrusions 77 and 77 are prevented from coming off from the recess 80. Is prevented by. For this reason, even when an external force in the longitudinal direction of the vehicle body is applied to the vehicle body, the slider 71 and the wind screen 51 are restricted to this position.

That is, since the weights of the slider 71 and the wind screen 51 are supported by the concave portion 80 provided integrally with the rail 61, the spring force of the locking pieces 90, 90 is approximately equal to the external force in the forward direction of the vehicle body during traveling. What is necessary is just to set to the comparatively small spring force of the grade which 2 protrusions 77 and 77 do not detach from the recessed part 80. FIG. During traveling, the traveling wind hits the wind screen 51, so that an external force (wind force) acting rearward acts on the wind screen 51 and the slider 71. Since this external force is also supported by the recess 80, the locking piece 90 It does not have to be supported.
Therefore, the operation force required when the second protrusions 77, 77 of the slider 71 are locked to the locking pieces 90, 90 and the force required to pull out the second protrusions 77, 77 from the locking pieces 90, 90 are required. The operating force required for engaging / disengaging with the locking pieces 90, 90 can be reduced.

  In addition, when the second protrusions 77 and 77 of the slider 71 are inserted into the recess 80 and the height of the wind screen 51 is fixed, when the operation of tilting the wind screen 51 from the rear side to the front side is performed, the slider 71 rotates about the first protrusions 76, 76, and the second protrusions 77, 77 of the slider 71 come out of the locking pieces 90, 90 and come out of the recess 80. Also in this case, the slider lever 71 is more than the case where the slider 71 is tilted directly by hand because the “lever principle” is used and the spring force of the locking piece 90 is set to a relatively small spring force. The operating force can be greatly reduced.

When the second protrusions 77 and 77 of the slider 71 are disengaged from the locking pieces 90 and 85, the second protrusions 77 and 77 enter the openings 68 and 68 by the rotation of the slider 71. Is movable along the rail 61, that is, the wind screen 51 is movable up and down.
Accordingly, after the user moves the wind screen 51 to a desired height, the second projections 77 and 77 of the slider 71 are placed in another recess 80 by performing an operation of tilting the wind screen 51 toward the vehicle body rear side. The wind screen 51 can be held at the height by being locked to the locking pieces 90 and 90. In this configuration, as shown in FIG. 3, the recesses 80 are provided at five positions at intervals in the longitudinal direction of the rail 61, so that the height of the wind screen 51 can be adjusted in five stages.

  As described above, according to the present embodiment, the left and right sliders 71 are provided with the second protrusions 77 and 77 that protrude from the slider body 72 in the left-right direction and engage with the rail 61, and the second protrusions 77 and 77. Since the recesses 80 are fitted in each rail 61 in the longitudinal direction of the vehicle body and are arranged at predetermined intervals in the longitudinal direction of the rail, the windscreen 51 and the slider 71 are fitted. Can be supported by the recess 80. For this reason, the spring which supports the self-weight of the wind screen 51 and the slider 71 is unnecessary, and the holding force of the wind screen 51 can be secured while reducing the operation force required for the screen moving operation. Therefore, even in a vehicle that travels on rough terrain with vertical movement of the vehicle body, it is possible to sufficiently secure the holding force of the wind screen 51 while reducing the operating force required for the screen moving operation.

Further, in this configuration, the slider 71 is provided with first protrusions 76 and 76 and second protrusions 77 and 77 that protrude in the left-right direction at the lower and upper ends of the slider main body 72 and engage with the rail 61. Since the second protrusions 77 and 77 at the upper end of the slider main body 72 are fitted in the recess 80, the first protrusions 76 and 76 can be used as the rotation fulcrum by an easy operation to tilt the wind screen 51 to the rear side of the vehicle body. The two protrusions 77 and 77 can be fitted into the recess 80.
Furthermore, in this configuration, since the recess 80 provided in the rail 61 is provided with the locking pieces 90 and 90 that lock the second projections 77 and 77 when the second projections 77 and 77 are fitted, Even when a strong forward force is applied to the vehicle body, the second protrusions 77 and 77 can be reliably held in the recess 80. In this case, since the locking pieces 90 and 90 do not need to support the weight of the wind screen 51, a sufficient holding force can be secured without increasing the spring force of the locking pieces 90 and 90. The operating force required for engagement / disengagement with 90, 90 can be reduced.
Further, in this configuration, when the second projections 77 and 77 are outside the recess 80, the spring force of the locking pieces 90 and 90 does not act on the slider 71 at all, so that the operating force required for the vertical movement of the wind screen 51 is also light. can do.

As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this, A various design deformation | transformation can be performed. For example, in the above-described embodiment, the case where the concave portion 80 that is recessed obliquely rearward and downward is formed in the rail 71 is not limited to this, and the concave portion that is recessed in the direction in which the weight of the wind screen 51 can be supported is widely applicable. is there.
In the above-described embodiment, the description has been given of the case where the concave portion 80 for regulating the position of the wind screen 51 is provided in the vehicle body rearward direction of the rail 61. It may be. When the concave portion 80 is provided in the vehicle body front direction of the rail 61, for example, the first protrusions 76 and 76 and the second protrusions 77 and 77 are formed in a shape opposite to that of the above embodiment, and the wind screen 51 is formed on the vehicle body. By tilting backward, the first protrusions 76, 76 can be fitted into the recess 80 with the second protrusions 77, 77 provided at the upper end of the slider main body 72 as a rotation fulcrum. In this case, since the concave portion 80 provided in the vehicle body front direction of the rail 61 supports the weight of the wind screen 51 and the slider 71 acting on the first protrusions 76 and 76, a spring for supporting the weight of the wind screen 51 and the slider 71 becomes unnecessary. Further, it is possible to secure the holding force of the wind screen 51 while reducing the operation force required for the screen moving operation.

In the above-described embodiment, the case where the present invention is applied to a manual windscreen support structure has been described. However, the present invention may be applied to a case where the windscreen is driven by a drive source such as a motor. For example, the push cables may be extended from the sliders 71 and 71, and the sliders 71 and 71 may be moved up and down by winding or pulling out the push cables with a motor-driven winding mechanism.
In the present embodiment, the case where the present invention is applied to the screen structure of the motorcycle 10 described above has been described. However, the present invention is not limited to this, and can be widely applied to the screen support structure of other motorcycles such as a scooter type vehicle. It is.
