Description

[Technical Field]

[0001] The present invention relates to a windscreen device. [Background technology]

[0002] BACKGROUND ART Conventionally, there is known a windscreen device that includes a windscreen that rises in front of the riding position and a screen support mechanism that enables the windscreen to be manually raised and lowered (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-007195 [Patent Document 2] Patent No. 7194262 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional configuration, the operating units for unlocking the windscreen height adjustment are provided on both the left and right sides of the screen support mechanism. To unlock the windscreen height adjustment, the user must simultaneously pull both operating units outward in the left and right directions. This requires the user to use both hands to adjust the windscreen height, and there is a demand for a configuration that makes it easier to adjust the windscreen height.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a windscreen device that allows the height of the windscreen to be adjusted with one hand. [Means for solving the problem]

[0006] As a means for solving the above problem, a first aspect of the present invention provides a windscreen device (30) including: a windscreen (31); a holder (50) that supports the windscreen (31); a bracket (40) that supports the holder (50) together with the windscreen (31) so that they can move up and down and is fixed to the vehicle body; and a shaft (53) that extends along the left-right direction of the vehicle and penetrates through and connects first connecting portions (54L, 54R) of the holder (50) and second connecting portions (42L, 42R) of the bracket (40) in the left-right direction of the vehicle. In the vehicle, one of the first connecting portions (54L, 54R) and the second connecting portions (42L, 42R) is a shaft holding portion (54L, 54R) that holds the shaft (53) so that it cannot move relatively when viewed from the left-right direction of the vehicle, and the other of the first connecting portions (54L, 54R) and the second connecting portions (42L, 42R) is a slide groove forming portion (42L, 42R) that forms a slide groove (42a) that extends in the vehicle up-down direction and allows the shaft holding portion (54L, 54R) to slide along the groove length direction of the slide groove (42a). By sliding the shaft holding parts (54L, 54R) in this manner, the height of the windscreen (31) can be adjusted together with the holder (50). The slide groove forming parts (42L, 42R) are provided with fitting members (46L, 46R) that are supported by the shaft (53) and can move integrally with the shaft (53) in the left-right direction of the vehicle. At the same time, fitting recesses (45L, 45R) that partially widen the groove width and allow the fitting members (46L, 46R) to fit into are formed at a plurality of locations spaced apart in the groove length direction of the slide groove (42a). The members (46L, 46R) and the fitting recesses (45L, 45R) constitute lock operating sections (47L, 47R) that switch between a locked state (S1) in which the shaft holding sections (54L, 54R) cannot slide relative to the slide groove forming sections (42L, 42R) and an unlocked state (S2) in which the shaft holding sections (54L, 54R) can slide relative to the slide groove forming sections (42L, 42R).An operating unit (65) is provided that can switch the locking state (S1) of the locking lever (47R) between an unlocked state (S2) and a locked state (S3), and the operating unit (65) is provided on only one side of the shaft (53) in the left-right direction of the vehicle. With this configuration, by providing an operating part for switching between locking and unlocking the lock operating part on only one side of the shaft in the left-right direction of the vehicle that connects the holder that supports the windscreen to the bracket fixed to the vehicle body, the occupant (user) can adjust the height of the windscreen with one hand.This makes the height adjustment easier to operate and reduces the number of parts compared to when switching between locking and unlocking the lock operating part using operating parts on both the left and right sides.

[0007] In a second aspect of the present invention, in the first aspect described above, a pair of lock operating parts (47L, 47R) are provided on the left and right, and the states of the pair of left and right lock operating parts (47L, 47R) can be simultaneously switched by an operating part (65) on one of the left and right sides. With this configuration, the pair of left and right lock operating parts can be switched between locked and unlocked simultaneously by operating the operating part on one side of the vehicle in the left-right direction, so that the windscreen height can be adjusted stably using the pair of left and right lock operating parts, while the windscreen height can be adjusted with one hand.

[0008] In a third aspect of the present invention, in the first or second aspect, the lock operating portion (47L, 47R) moves the engaging members (46L, 46R) to the other side in the left-right direction of the vehicle to enter a locked state (S1), and moves the engaging members (46L, 46R) to one side in the left-right direction of the vehicle to enter an unlocked state (S2), and the engaging members (46L, 46R) are biased to the other side in the left-right direction of the vehicle by an elastic member (57). According to this configuration, the engaging member of the lock operating unit is biased toward the other side (lock side) of the vehicle in the left-right direction by the elastic member, so that after operating the operating unit to one side (unlock side) in the left-right direction of the vehicle to adjust the screen height, the lock operating unit can be returned to the locked state simply by releasing the operating unit, making it easier to adjust the windscreen height.

[0009] A fourth aspect of the present invention is any one of the first to third aspects, wherein at least one of the first mating surface (46b) that mates with the mating recess (45L, 45R) of the mating member (46L, 46R) and the second mating surface (45b) that mates with the mating member (46L, 46R) in the mating recess (45L, 45R) is a tapered surface (45b, 46b) whose cross-sectional shape narrows toward the other side in the left-right direction of the vehicle. With this configuration, the mating surfaces of at least one of the mating members and mating recesses are tapered, so that even if the relative positions of the mating members and mating recesses are slightly misaligned, the tapered surfaces can guide the mating members and mating recesses to their specified relative positions. Furthermore, when the mating members are biased in the mating direction, the wedge effect of the tapered surfaces ensures that the mating members and mating recesses fit together securely and without play, even with limited biasing force. This makes screen height adjustment even easier.

[0010] A fifth aspect of the present invention is any one of the first to fourth aspects, wherein the operating portion (65) is provided with a grip portion (68) that extends rearward relative to the shaft (53) when viewed in the axial direction of the shaft (53). According to this configuration, the operating unit is provided with a grip portion that extends rearward from the shaft, making it easier to see and reach the grip portion from behind the operating unit (on the passenger side), thereby improving the operability of the operating unit.

[0011] A sixth aspect of the present invention is any one of the first to fifth aspects, wherein the operating portion (65) is provided with a grip portion (68) that is offset outward in the left-right direction of the vehicle relative to a base portion (66) that fixes the end of the shaft (53). According to this configuration, the operating unit has a grip portion that is offset further outward in the left-right direction of the vehicle than the end of the shaft, making it easier to ensure clearance so that the hand can reach inside the grip portion in the left-right direction of the vehicle regardless of the left-right position of the end of the shaft, thereby improving the operability of the operating unit.

[0012] A seventh aspect of the present invention is any one of the first to sixth aspects, wherein the lock operating portion (47L, 47R) has a rotation restriction structure (48) that restricts rotation of the operating portion (65) about the shaft (53) in the locked state (S1). With this configuration, the lock operating unit has a rotation restriction structure that restricts the rotation angle of the operation unit in the locked state, so that the rotation angle of the operation unit after screen height adjustment (locked state) can be set to a desired angle that has been set in advance. As a result, the operation unit can be maintained at an angle that is easy to hold after screen height adjustment. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a windscreen device that allows the height of the windscreen to be adjusted with one hand. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, directions such as front, rear, left, and right are the same as directions in the vehicle described below unless otherwise specified. In addition, in the drawings used in the following description, an arrow FR indicating the front of the vehicle, an arrow LH indicating the left side of the vehicle, an arrow UP indicating the top of the vehicle, and a line CL indicating the center of the vehicle body to the left and right are shown in appropriate positions.

[0016] <Entire vehicle> FIG. 1 shows a scooter-type motorcycle (saddle-ride type vehicle) 1 as an example of a saddle-ride type vehicle according to an embodiment. The motorcycle 1 has a front wheel 3, which is a steering wheel, and a rear wheel 4, which is a drive wheel. The front wheel 3 is supported by a front fork 3a and can be steered by a handlebar 2. The rear wheel 4 is supported by, for example, a swing-type power unit 5 and can be driven by the power unit 5. The swing-type power unit 5 integrally includes a prime mover, such as an internal combustion engine or an electric motor, and a transmission that transmits the output of the prime mover to the rear wheel 4.

[0017] Steering system components including the handlebars 2, front forks 3a, and front wheel 3 are steerably supported on a head pipe 11a at the front end of a body frame 11. The front portion of a swing-type power unit 5 is supported in a vertically swingable manner in the middle between the front and rear of the body frame 11. The rear portion of the power unit 5 is supported in the rear portion of the body frame 11 via a rear cushion 4a. Note that "middle" in the embodiments is not limited to "center."

[0018] In the embodiment, a telescopic front fork 3a is used as an example of the front wheel suspension of the motorcycle 1, but the configuration is not limited to this. For example, the front wheel suspension may be of another type, such as a link type using a swing arm. The motorcycle 1 is not limited to a unit swing type vehicle as described above, but may be a vehicle in which the prime mover is fixedly mounted on the body frame 11.

[0019] A seat 15 on which a passenger sits is disposed behind the handlebars 2. A low floor section 6 of the vehicle body is provided between the handlebars 2 and the seat 15. A straddling space K1 is formed above the low floor section 6 to make it easier for the passenger to straddle the vehicle body. The low floor section 6 is equipped with a pair of left and right floor steps 7 on which the driver seated in the seat 15 places his or her left and right feet, and a center tunnel 7a extending in the fore-and-aft direction of the vehicle between the left and right floor steps 7.

[0020] <Body frame 11> Referring to FIG. 1, the body frame 11 includes a head pipe 11a, a down frame 11b extending downward and rearward from the head pipe 11a, a lower frame 11c extending rearward from the lower end of the down frame 11b, a center frame 11d extending rearward and upward from the rear end of the lower frame 11c, a middle frame 11e installed between the down frame 11b and the center frame 11d, and a rear frame 11f having a front end connected to the upper rear side of the middle frame 11e and extending rearward and upward from the front end.

[0021] The upper end of the center frame 11d is connected to the lower front side of the rear frame 11f. The down frame 11b, the lower frame 11c, and the center frame 11d are configured as an integrated frame member that is continuous via a bent portion. The down frame 11b, the lower frame 11c, and the center frame 11d, as well as the middle frame 11e and the rear frame 11f, are provided on both the left and right sides of the vehicle body, forming left and right pairs.

[0022] <Body Cover 21> The periphery of the body frame 11 is covered with a body cover 21. The body cover 21 includes left and right floor steps 7, a center tunnel 7a, a front body cover 22 connected to the front of the left and right floor steps 7 and the center tunnel 7a, and a rear body cover 23 connected to the rear of the left and right floor steps 7 and the center tunnel 7a.

[0023] An item storage box (not shown) is disposed inside the rear body cover 23. The item storage box has a container shape that opens upward. The upper opening of the item storage box can be opened and closed by rotating the seat 15 via a hinge (not shown) on the front end side.

[0024] 3, a windscreen 31 that rises up in front of the riding position of the motorcycle 1 is disposed above and in front of the front body cover 22. The windscreen 31 is supported by the vehicle body, which includes the front body cover 22 and a cover support frame (not shown), via a screen support mechanism 35. The windscreen 31 (screen main body) and the screen support mechanism 35 are included in a windscreen device 30 of the motorcycle 1.

[0025] <Windscreen device 30> FIG. 2 is a front view (front view) of the periphery of the windscreen 31, and FIG. 3 is a left side view of the periphery of the windscreen 31. 1 to 3, the windscreen 31 extends upward and rearward from its lower end in front of the riding position where the rider operates the motorcycle 1. The windscreen 31 extends upward and rearward from its lower end at an angle in side view. The windscreen 31 can be raised and lowered by manually operating a screen support mechanism 35 (movable mechanism).

[0026] The lower part of the windscreen 31 is fixed to a holder 50 of the screen support mechanism 35. The holder 50 is supported by a bracket 40 fixed to the vehicle body of the screen support mechanism 35 so that it can be raised and lowered up and down. The screen support mechanism 35 is equipped with an operation unit 65 on the left side of the vehicle that allows manual operation by the driver (passenger, user). The screen support mechanism 35 allows the windscreen 31 to be raised and lowered up and down by the user manually operating the operation unit 65.

[0027] 1, a meter device 8 is disposed above the front body cover 22 and in front of the handlebars 2. The meter device 8 functions as an instrument that indicates, for example, vehicle speed and engine RPM. The meter device 8 is supported by the front body cover 22 and a cover support frame (not shown), for example, separate from steering system components. The meter device 8 is configured with a display device such as a liquid crystal display that displays various information about the motorcycle 1 as images. The meter device 8 is disposed with, for example, a rectangular display screen facing rearward (toward the rider).

[0028] The meter device 8 is supported by a meter support portion 41 that is integrally formed at the rear portion of a bracket 40 of the screen support mechanism 35. A meter visor 41a is integrally formed at the top of the meter support portion 41. The meter visor 41a extends rearward from an area spanning the upper edge and the upper portions of the left and right side edges of the meter device 8, and covers the upper part of the display screen. The meter visor 41a functions as a canopy, preventing external light from being reflected on the display screen and making it difficult to see.

[0029] If the meter support configuration including the meter support portion 41 and the meter visor 41a and the screen support configuration (bracket 40) are separate from each other, a structure for connecting these two configurations is required. In contrast, by integrally forming the meter support configuration with the bracket 40 of the screen support mechanism 35 as in the embodiment, a structure for connecting the meter support configuration and the screen support configuration is not required, and both configurations can be arranged compactly.

[0030] <Windscreen 31> 2 and 3, the windscreen 31 is formed into a plate shape from, for example, a transparent resin material. The windscreen 31 has a gently bulging shape that protrudes upward and forward to match the vehicle exterior. The windscreen 31 controls the flow of wind toward the rider when the motorcycle 1 is traveling forward.

[0031] 2, the windscreen 31 has an upper edge 31a that extends substantially horizontally in a front view from the front-rear direction, left and right side edge portions 31b that extend downward from the left and right ends of the upper edge 31a, and a lower edge portion 31c that spans between the lower ends of the left and right side edge portions 31b. The left and right side edge portions 31b are each formed in a shallow V-shape that convex outward in the left-right direction of the vehicle in a front view. The lower edge portion 31c is formed in a curved shape that convex downward in a front view. The windscreen 31 is formed symmetrically with respect to the vehicle body left-right center line CL as an axis of symmetry.

[0032] FIG. 4 is a left side view of the windscreen 31 when it is at the lowest position P1, and FIG. 5 is a left side view of the windscreen 31 when it is at the highest position P2. The windscreen 31 is supported on the vehicle body by a screen support mechanism 35 so that its height can be adjusted. By operating the screen support mechanism 35, the windscreen 31 can be moved in both directions between a lower limit position P1 shown in Figure 4 and an upper limit position P2 shown in Figure 5.

[0033] When in the lower limit position P1, the windscreen 31 is inclined to follow the front upper surface 22a of the front body cover 22, which is inclined upward toward the rear, in a side view. The lower front end (lower edge 31c) of the windscreen 31 when in the lower limit position P1 is spaced above and rearward from the upper edge 24a of the headlight 24 (see FIG. 2). This prevents the windscreen 31 from affecting the light distribution of the headlight 24. The lower front end of the windscreen 31 when in the lower limit position P1 is spaced further outward (upper and forward) from the front upper surface 22a of the front body cover 22. This allows some of the traveling wind to be introduced between the windscreen 31 and the front body cover 22. The upper rear end of the windscreen 31 when in the lower limit position P1 is located above the meter visor 41a.

[0034] The windscreen 31 at the upper limit position P2 is moved rearward and upward so that its front lower end is aligned with the front upper surface 22a of the front body cover 22 more than when it is at the lower limit position P1, and is arranged to stand upright at a steeper incline than when it is at the lower limit position P1.

[0035] When in the upper limit position P2, the front lower end of the windscreen 31 is positioned upward enough to expose the front lower portion of the bracket 40 of the screen support mechanism 35. When in the upper limit position P2, the front lower end of the windscreen 31 is spaced further outward (upper and forward) from the vehicle than the front body cover 22 and the bracket 40. This makes it possible to introduce some of the traveling wind between the windscreen 31 and the front body cover 22, just as when the windscreen 31 is in the lower limit position P1. When in the upper limit position P2, the rear upper end of the windscreen 31 moves upward more than when in the lower limit position P1, further reducing the amount of traveling wind blowing toward the driver.

[0036] FIG. 8 is a perspective view of the screen support mechanism 35. 3 and 8, fastening recesses 32 are formed on both the left and right sides of the middle part of the windscreen 31 in the vertical direction, to be fastened to the four support arms 51a of the holder 50. Each fastening recess 32 recesses the corresponding part of the windscreen 31 toward the inside of the vehicle (rearward and downward) in the normal direction to the outer surface of the windscreen 31. Each fastening recess 32 is circular when viewed from the normal direction, and has a bolt insertion hole formed in the center. The head of a fixing bolt B1 that screws into the support arm 51a of the holder 50 is recessed into each fastening recess 32.

[0037] 2, a running wind intake 33 having an inverted trapezoidal shape when viewed from the front-to-rear direction is formed in the center of the vehicle in the left-to-right direction at the bottom of the windscreen 31 (a portion below the center in the up-down direction). The running wind intake 33 has an inclined surface 33a that slopes so that its depth toward the inside of the vehicle (rear-downward) increases toward the upper end of the inverted trapezoid, and a horizontally elongated air guide port 33b that penetrates in the front-to-rear direction is formed at the upper end. When viewed from the front-to-rear direction, the air guide port 33b is positioned so as to overlap with an air guide passage 51b (described later) on the inside of the holder 50 in the left-to-right direction of the vehicle.

[0038] <Screen support mechanism 35> FIG. 6A is a cross-sectional view taken along line VI-VI in FIG. 4, 6(A), and 8, the windscreen support mechanism 35 includes a bracket 40 fixed to the vehicle body, a holder 50 movably supported by the bracket 40, and a windscreen 31 attached to the holder 50. The bracket 40 and the holder 50 are each formed from, for example, synthetic resin.

[0039] The holder 50 comprises a plate-shaped holder main body 51 that is arranged below and behind the windscreen 31 (on the inner surface, vehicle body side), and a pair of left and right arm portions 52 that extend below and behind from the vehicle body side of the upper part of the holder main body 51. The holder main body 51 is arranged at an angle that rises toward the rear so as to fit along the inner surface (back surface) of the windscreen 31 in a side view. Left and right shaft holding portions 54L, 54R (first connecting portions) are configured at the tip portions (lower rear ends) of the left and right arm portions 52 that pass through and hold the left and right side portions of a shaft 53 that extends in the left and right direction of the vehicle.

[0040] 6(A), the left and right shaft holding portions 54L, 54R hold the shaft 53 so that it cannot move relative to the shaft 53 when viewed in the left-right direction of the vehicle. The left and right shaft holding portions 54L, 54R allow axial movement and rotation of the shaft 53. The left and right shaft holding portions 54L, 54R each include a cylindrical cup portion 55 with a bottom that opens toward the other side (right side) in the left-right direction of the vehicle, spring seats 56L, 56R that are arranged to close the open portion of the cup portion 55, and a coil spring 57 that is compressed between the bottom of the cup portion 55 and the spring seats 56L, 56R.

[0041] Each spring seat 56L, 56R has an insertion hole 56a through which the shaft 53 is inserted, and an elastic piece 56b (locking claw) extending obliquely toward the other side (right side) in the vehicle left-right direction from the inner periphery of the insertion hole 56a. The elastic pieces 56b of the spring seats 56L, 56R fit into and engage with notches 53a formed partially on the outer periphery of the shaft 53. This restricts rightward movement of the spring seats 56L, 56R relative to the shaft 53. The biasing force of the coil spring 57 acts on the spring seats 56L, 56R in the rightward direction, biasing the shaft 53 together with the spring seats 56L, 56R rightward.

[0042] 4 and 8, support arms 51a are formed at the four corners of the rectangular holder main body 51, extending toward the inner surface (back surface) of the windscreen 31. Each support arm 51a extends obliquely forward and outward to the left and right from the four corners of the holder main body 51. The upper front surface of the holder main body 51 forms an air guide passage 51b that is recessed downward and rearward between the left and right support arms 51a.

[0043] The air guide passage 51b faces the air guide opening 33b of the windscreen 31. The air guide passage 51b guides the traveling wind that is introduced from the air guide opening 33b to the back side of the windscreen 31 in an upward and rearward direction while rectifying the flow. The air guide passage 51b opens to the lower front end of the holder 50. The air guide passage 51b guides a portion of the traveling wind that is introduced from the lower front end of the windscreen 31 between the windscreen 31 and the front body cover 22 in an upward and rearward direction while rectifying the flow.

[0044] The front end of the holder 50 and the front end of the bracket 40 are connected via a link member 61. One end 61a of the link member 61 is connected to a link connecting portion 51c extending downward and forward from the front end of the holder main body 51 via a shaft extending in the left-right direction of the vehicle so as to be rotatable relative to the bracket 40. The other end 61b of the link member 61 is connected to the front end of the bracket 40 via a shaft extending in the left-right direction of the vehicle so as to be rotatable relative to the bracket 40.

[0045] When the windscreen 31 is at the lowest position P1, the link member 61 is positioned so as to extend generally horizontally (more specifically, tilted slightly upward at the front) from the bracket 40 side toward the front. As the windscreen 31 rises from the lowest position P1 toward the highest position P2, the link member 61 rotates upward at the front about the other end 61b side, causing the one end 61a side to follow the upward movement of the windscreen 31. When the windscreen 31 reaches the highest position P2, the link member 61 is positioned so as to extend generally vertically upward from the bracket 40 side (see FIG. 5).

[0046] The bracket 40 comprises a base portion (not shown) fixed to at least one of the front body cover 22 and a support stay (not shown) fixed to the body frame 11 inside the front body cover 22, and a pair of left and right slide groove forming portions 42L, 42R (second connecting portions) extending obliquely rearward and upward in a side view from both the left and right sides of the base portion and supporting the holder 50 so that it can slide.

[0047] Referring also to FIG. 6(A), the left and right slide groove forming portions 42L, 42R are formed symmetrically with respect to the vehicle's left-right center line CL. The left and right slide groove forming portions 42L, 42R are formed in an arc shape that convexly extends forward and upward in a side view. The left and right slide groove forming portions 42L, 42R are formed with slide grooves 42a that extend in an inclined and curved manner so as to follow the left and right slide groove forming portions 42L, 42R in a side view. The slide grooves 42a penetrate the corresponding slide groove forming portions in the left-right direction of the vehicle over their entire length. The slide grooves 42a are inclined and curved so that the upper portions are positioned rearward in a side view, but extend vertically from one end of the groove length direction to the other end without turning back vertically.

[0048] The left and right slide groove forming portions 42L, 42R connect the left and right shaft holding portions 54L, 54R of the holder 50 via the left and right side portions of the shaft 53, respectively. The left and right slide groove forming portions 42L, 42R enable the left and right shaft holding portions 54L, 54R of the holder 50 to slide along the length direction of the slide groove 42a, respectively. By sliding the left and right shaft holding portions 54L, 54R up and down along the left and right slide groove 42a, the windscreen 31 can be raised and lowered (height adjustable) together with the holder 50.

[0049] The left and right slide groove forming portions 42L, 42R form slide grooves 42a in an inner wall 43 located on the inside in the vehicle left-right direction. The inner wall 43 has an outer shape that is slightly larger than the slide groove 42a in a side view. An outer peripheral wall 43a extends from the outer peripheral edge of the inner wall 43 toward the outer wall of the corresponding slide groove forming portion on the outside in the vehicle left-right direction. A portion of lock operating portions 47L, 47R, which will be described later, is accommodated in a recessed space 43b surrounded by the outer peripheral wall 43a and the inner wall 43. Left and right guide walls 44L, 44R are formed on the outer side of the inner wall 43 in the vehicle left-right direction, extending from the outer peripheral edge of the shape of the slide groove 42a in a side view toward the outside in the vehicle left-right direction (into the recessed space 43b).

[0050] In a side view, fitting recesses 45L, 45R are formed in a plurality of spaced locations in the groove length direction of the slide groove 42a on the left and right guide walls 44L, 44R, respectively, so as to partially widen the groove width of the slide groove 42a. Each fitting recess 45L, 45R forms a space wider than the slide groove 42a in the groove width direction of the slide groove 42a. Each fitting recess 45L of the left slide groove forming portion 42L can fit a left fitting member 46L from the left side (outside in the vehicle left-right direction), and each fitting recess 45R of the right slide groove forming portion 42R can fit a right fitting member 46R from the left side (inside in the vehicle left-right direction).

[0051] A pair of left and right fitting members 46L, 46R are disposed in the left and right slide groove forming portions 42L, 42R, respectively, which are supported on the left and right sides of the shaft 53 and are movable integrally with the shaft 53 in the left-right direction of the vehicle. The left engaging member 46L is positioned to the left of the inner wall 43 (outside the left-right direction of the vehicle) within the recessed space 43b of the left slide groove forming portion 42L, and can be engaged with and disengaged from the left (outside the left-right direction of the vehicle) into multiple engaging recesses 45L formed in the left guide wall 44L. The right engaging member 46R is positioned to the left (inside the left-right direction of the vehicle) of the inner wall 43 of the right slide groove forming portion 42R, and can be engaged with and disengaged from the left (inside the left-right direction of the vehicle) into multiple engaging recesses 45R formed in the right guide wall 44R.

[0052] The combination of the left fitting member 46L and the left fitting recess 45L, and the combination of the right fitting member 46R and the right fitting recess 45R, constitute a pair of left and right lock operating portions 47L, 47R. The left and right lock operating portions 47L, 47R are switchable between a locked state S1 in which the shaft holding portion on that side is engaged with the left and right slide groove forming portions 42L, 42R so as not to slide, and an unlocked state S2 (see FIG. 7) in which the shaft holding portion on that side is slidable relative to the left and right slide groove forming portions 42L, 42R.

[0053] The shaft 53 is a steel material with a circular cross section that extends across the entire width of the screen support mechanism 35, and the left and right sides of the shaft 53 pass through the left and right shaft holding portions 54L, 54R and the left and right slide groove forming portions 42L, 42R, respectively. The shaft 53 connects the shaft holding portions and slide groove forming portions on the same left and right sides of the screen support mechanism 35 so that they can rotate relatively around the center of the shaft 53.

[0054] The left side of the shaft 53 penetrates the shaft holding portion 54L of the left arm portion 52, protruding leftward, and passes through a predetermined position in the groove length direction of the slide groove 42a of the left slide groove forming portion 42L, further protruding leftward. The left side of the shaft 53 penetrates the left fitting member 46L in the recessed space 43b of the left slide groove forming portion 42L and is inserted into an operating portion 65 located on the outer side of the left slide groove forming portion 42L in the vehicle left-right direction. The left end of the shaft 53 is, for example, a threaded shaft, and the operating portion 65 is fixed to this left end by a fastening structure using a nut or the like. In this embodiment, the left fitting member 46L is integrated with the inner side of the operating portion 65 in the vehicle left-right direction, allowing the operating portion 65, the left fitting member 46L, and the shaft 53 to move together in the vehicle left-right direction. Note that the operating portion 65 and the left fitting member 46L may be configured separately.

[0055] The right side of the shaft 53 penetrates the shaft holding portion 54R of the right arm portion 52 and protrudes rightward, passes through a predetermined position in the groove length direction of the slide groove 42a of the right slide groove forming portion 42R, and protrudes further rightward. The right side of the shaft 53 penetrates a right fitting member 46R disposed to the left of the inner wall 43 of the right slide groove forming portion 42R (inner side in the vehicle left-right direction). The right guide wall 44R extends to near the right end of the recessed space 43b of the right slide groove forming portion 42R. The right end of the shaft 53 extends to near the right end of the right guide wall 44R (more specifically, between the right end of the right guide wall 44R and the right end of the recessed space 43b).

[0056] In this embodiment, the right fitting member 46R is integrated with the right side of the right spring seat 56R, and the right fitting member 46R is biased rightward by a right coil spring 57. When the operating portion 65 and the shaft 53 move leftward, the right spring seat 56R and the right fitting member 46R can move leftward against the biasing force of the right coil spring 57. Note that the right spring seat 56R and the right fitting member 46R may be configured as separate members.

[0057] An operating unit 65 is fixed to one end of the shaft 53 in the left-right direction of the vehicle (the left end in this embodiment). The operating unit 65 is provided only on the left side of the shaft 53, and not on the right side of the shaft 53. The operating unit 65 and the shaft 53 can be moved in the axial direction (the left-right direction of the vehicle) by a specified amount to one side (left) in the left-right direction of the vehicle. By operating and releasing the operating unit 65, the shaft 53 and the left and right fitting members 46L, 46R can be moved in the left-right direction of the vehicle, and this movement can simultaneously switch the left and right lock operating units 47L, 47R between a locked state S1 and an unlocked state S2 (see FIG. 7). Details of the operating unit 65 will be described later.

[0058] FIG. 7 is a cross-sectional view similar to FIG. 6(A), showing the unlocked state S2 of the left and right lock operating portions 47L, 47R. Referring to FIG. 6A, the left and right lock operating parts 47L, 47R are respectively placed in a locked state S1 by moving the left and right fitting members 46L, 46R to the other side in the left-right direction of the vehicle (the right side, the side of the shaft 53 opposite the operating part 65). 7, the left and right lock operating parts 47L, 47R are each set to the unlocked state S2 by moving the left and right fitting members 46L, 46R to one side in the vehicle left-right direction (the left side, the operating part 65 side of the shaft 53).

[0059] The shaft 53 and the left and right fitting members 46L, 46R are biased rightward relative to the left and right shaft holding portions 54L, 54R by the coil springs 57. Therefore, the operating portion 65 is pulled leftward against the biasing force of the left and right coil springs 57.

[0060] When adjusting the height of the windscreen 31, the user first pulls the operating unit 65 on the left side of the shaft 53 to the left to release the locked state S1 of the left and right lock operating units 47L, 47R. In this embodiment, by operating the operating unit 65 provided on one side of the shaft 53 in the left-right direction of the vehicle, the locked state S1 of the left and right lock operating units 47L, 47R can be released simultaneously, making the operation to release the lock of the left and right lock operating units 47L, 47R easier than in a configuration in which operating units are provided on both the left and right sides and operated. The occupant can generally operate the operating unit 65 with their left hand while operating the brake lever supported on the right side of the handlebars 2.

[0061] The user pulls the operating unit 65 to the left, and together with the operating unit 65, pulls the shaft 53 and the left and right fitting members 46L, 46R to the left, thereby maintaining the unlocked state S2 and sliding the operating unit 65, shaft 53, and left and right fitting members 46L, 46R along the left and right slide groove 42a. This causes the left and right shaft holding units 54L, 54R, which coaxially hold the shaft 53, to slide along the left and right slide groove 42a, moving the upper part of the holder 50 and the vertical middle part of the windscreen 31 along the left and right slide groove 42a. At this time, the lower part of the holder 50 and the lower part of the windscreen 31 move along the rotation trajectory of the link member 61, causing the holder 50 and the windscreen 31 to move up and down while tilting overall.

[0062] When the windscreen 31 reaches the desired height, the user releases the operation of pulling the operating unit 65 to the left, and the left and right fitting members 46L, 46R move to the right due to the biasing force of the left and right coil springs 57. At this time, if the left and right fitting members 46L, 46R are positioned so that they overlap with one of the fitting recesses in side view, the left and right fitting members 46L, 46R fit into the corresponding fitting recess. This returns the left and right lock operating units 47L, 47R to the locked state S1, fixes the windscreen 31 at the desired height, and completes the screen height adjustment. Performing this series of actions by operating the operating unit 65 provided on one of the left and right sides of the shaft 53 simplifies screen height adjustment.

[0063] Here, the engagement structure between the notch 53a of the shaft 53 and each spring seat 56L, 56R restricts rightward movement of each spring seat 56L, 56R relative to the shaft 53, while allowing a specified amount of leftward movement of each spring seat 56L, 56R relative to the shaft 53. Therefore, even if, for example, the right fitting member 46R of the left and right lock operating portions 47L, 47R first fully engages with the fitting recess 45R, the shaft 53 and the left fitting member 46L can then be moved further rightward relative to the right spring seat 56R, allowing the left fitting member 46L to engage. In this way, even if there is variation in the lock positions of the left and right lock operating portions 47L, 47R, the left and right lock operating portions 47L, 47R can be reliably placed in the locked state S1.

[0064] FIG. 6B is a cross-sectional view taken along the line BB in FIG. 6A. 6(A) and 6(B), at least one of the left and right lock operating parts 47L, 47R (in the embodiment, both of the left and right lock operating parts 47L, 47R) has a rotation restricting structure 48 that restricts rotation of the operating part 65 about the shaft 53 in the locked state S1. The rotation restricting structure 48 is realized by the cross-sectional shapes of the fitting members 46L, 46R and the fitting recesses 45L, 45R that are perpendicular to the axial direction of the shaft 53.

[0065] In the rotation restricting structure 48 of this embodiment, the cross-sectional shapes of the fitting members 46L, 46R and the fitting recesses 45L, 45R are circular and match each other, and the fitting members 46L, 46R and the fitting recesses 45L, 45R are fitted together to restrict rotation of the operating unit 65 about the shaft 53 in the locked state S1. Fig. 6(B) shows the configuration of the left lock operating unit 47L, but the right lock operating unit 47R has a similar configuration.

[0066] FIG. 9 is a left side view showing a structure for eliminating backlash in the rotation direction of the operation unit 65 of the screen support mechanism 35. Referring to FIG. 9 , the operating unit 65 includes a generally triangular sliding portion 69 on its inner side in the vehicle width direction, which fits into the outer peripheral wall 43a of the left slide groove forming portion 42L. The sliding portion 69 includes a pair of sliding contact portions 69a that slide against the outer peripheral wall 43a on the rear lower side (curved inner peripheral side) of the left slide groove forming portion 42L. The outer peripheral wall 43a is formed with seats 43c on which the sliding contact portions 69a rest when the fitting members 46L, 46R and the fitting recesses 45L, 45R are fitted together. In the unlocked state S2, the operating unit 65 can move along the left slide groove forming portion 42L with some play, while rotation is being restricted. In the specified position, the sliding contact portions 69a rest on the corresponding seats 43c, thereby eliminating backlash in the rotational direction. In this state, the left and right lock operating units 47L, 47R can be placed in the locked state S1.

[0067] Referring to Figures 6(A) and 7, at least one of the outer peripheral surfaces (first mating surfaces) of the mating members 46L, 46R that fit into the mating recesses 45L, 45R and the inner peripheral surfaces (second mating surfaces) of the mating recesses 45L, 45R that fit into the mating members 46L, 46R (in the embodiment, both the first mating surfaces and the second mating surfaces) is a tapered surface 45b, 46b whose cross-sectional shape narrows toward the other side in the left-right direction of the vehicle.

[0068] As a result, when the lock operating portions 47L, 47R are returned from the unlocked state S2 to the locked state S1, even if the relative positions of the fitting members 46L, 46R and the fitting recesses 45L, 45R are slightly misaligned in side view, once the tip ends of the fitting members 46L, 46R are inserted into the fitting recesses 45L, 45R, they are guided by the tapered surfaces 45b, 46b, and the misalignment of the relative positions of the fitting members 46L, 46R and the fitting recesses 45L, 45R is eliminated (they are returned to their normal relative positions), allowing the fitting members 46L, 46R and the fitting recesses 45L, 45R to be fitted together. The inclination angle of the tapered surfaces 45b, 46b with respect to the axial direction is small, and the wedge effect of the tapered surfaces 45b, 46b allows the fitting members 46L, 46R and the fitting recesses 45L, 45R to be reliably fitted together without any play with a limited biasing force.

[0069] Referring to Figures 6(A) and 8, the operating unit 65 comprises a base 66 in the form of a plate perpendicular to the axial direction of the shaft 53 and fixed directly to one end (left end) of the shaft 53 in the left-right direction of the vehicle, a protruding portion 67 protruding outward in the left-right direction of the vehicle from the rear of the base 66, and a gripping portion 68 in the form of a plate perpendicular to the axial direction of the shaft 53 and fixed to the outer end of the protruding portion 67 in the left-right direction of the vehicle.

[0070] The base 66 has an elliptical shape that is long in the front-rear direction when viewed in the axial direction of the shaft 53 (i.e., in a side view). The left end of the shaft 53 is fixed to the front part of the base 66 on the inner side in the left-right direction of the vehicle, and a protrusion 67 protrudes from the rear part, which is located rearward of the shaft 53 and on the outer side in the left-right direction of the vehicle. The center position of the front arc shape of the base 66 in a side view is located on an extension of the left end of the shaft 53.

[0071] The protruding portion 67 has, for example, a hollow cylindrical shape with its axial direction facing the left-right direction of the vehicle, and is arranged coaxially with the arc-shaped rear portion of the base portion 66 in a side view. The protruding portion 67 extends from the rear of the base portion 66 toward the left (outside in the left-right direction of the vehicle). The grip portion 68 has an elliptical shape that is long in the front-to-rear direction in a side view. When viewed in the axial direction of the shaft 53, the grip portion 68 includes a base portion 68a that fits within the range of the base radius from the axis of the protrusion 67, and an extension portion 68b that extends rearward from the axis of the protrusion 67 beyond the base radius.

[0072] The grip portion 68 is offset outward in the vehicle left-right direction from the base portion 66 adjacent to the left slide groove forming portion 42L, and extends further rearward (toward the occupant) from the base portion 66. As a result, the grip portion 68 projects outward in the vehicle left-right direction from the base portion 66 adjacent to the left slide groove forming portion 42L, and is positioned entirely rearward from the shaft 53. This makes the grip portion 68 easy for the occupant to see and grip, improving the ease of operation for adjusting the screen height. When the grip portion 68 is positioned so as to overlap with the shaft 53 in a side view, the portion rearward of the shaft 53 extends further rearward than the portion forward of the shaft 53.

[0073] The extension 68b of the grip 68 is tapered so that its vertical width narrows toward the rear in a side view. This increases the degree of freedom in the angle of the hand gripping the grip 68 while maintaining the size of the grip 68 in a side view. The extension 68b is also tapered so that its width in the left-right direction of the vehicle narrows toward the rear in a plan view, which also increases the degree of freedom in the angle of the hand gripping the grip.

[0074] As described above, the windscreen device 30 in the above embodiment includes the windscreen 31, the holder 50 that supports the windscreen 31, the bracket 40 that supports the holder 50 together with the windscreen 31 so that it can move up and down and is fixed to the vehicle body, and the shaft 53 that extends in the left-right direction of the vehicle and penetrates through and connects the first connecting portion (shaft holding portions 54L, 54R) of the holder 50 to the second connecting portion (slide groove forming portions 42L, 42R) of the bracket 40 in the left-right direction of the vehicle, one of the first connecting portion and the second connecting portion is the shaft holding portion 54L, 54R that holds the shaft 53 so that it cannot move relatively when viewed from the left-right direction of the vehicle, and the other of the first connecting portion and the second connecting portion is the slide groove forming portion 42L, 42R that forms the slide groove 42a that extends in the up-down direction of the vehicle and allows the shaft holding portions 54L, 54R to slide along the groove length direction of the slide groove 42a, and by sliding the shaft holding portions 54L, 54R along the slide groove 42a, the windscreen can be moved together with the holder 50. The height of the slide groove 42a is adjustable, and fitting members 46L, 46R that are supported by a shaft 53 and can move integrally with the shaft 53 in the left-right direction of the vehicle are disposed in the slide groove forming portions 42L, 42R, and fitting recesses 45L, 45R that partially widen the groove width and allow the fitting members 46L, 46R to fit are formed at a plurality of locations spaced apart in the groove length direction of the slide groove 42a, and the fitting members 46L, 46R and the fitting recesses 45L, 45R slide the shaft holding portions 54L, 54R relative to the slide groove forming portions 42L, 42R. Lock operating parts 47L, 47R are configured to switch between a locked state S1 in which the shaft holding parts 54L, 54R cannot be slid relative to the slide groove forming parts 42L, 42R, and an unlocked state S2 in which the shaft holding parts 54L, 54R can slide relative to the slide groove forming parts 42L, 42R. The shaft 53 is provided with an operating part 65 that moves the shaft 53 and the engaging members 46L, 46R in the left-right direction of the vehicle, making it possible to switch between the locked state S1 and the unlocked state S2 of the lock operating parts 47L, 47R, and the operating part 65 is provided on only one side of the shaft 53 in the left-right direction of the vehicle.

[0075] According to this configuration, by providing the operation unit 65 that switches between locking and unlocking the lock operation units 47L, 47R on only one side in the left-right direction of the vehicle of the shaft 53 that connects the holder 50 that supports the windscreen 31 and the bracket 40 that is fixed to the vehicle body, the occupant (user) can adjust the height of the windscreen 31 with one hand. Therefore, compared to when the lock operation units 47L, 47R are switched between locking and unlocking using the operation units 65 on both the left and right sides, the height adjustment operation is easier and the number of parts can be reduced.

[0076] In the windscreen device 30, the lock operating parts 47L, 47R are provided as a pair on the left and right, and the states of the pair of left and right lock operating parts 47L, 47R can be switched simultaneously by an operation part 65 on one of the left and right sides. According to this configuration, the pair of left and right lock operating parts 47L, 47R can be switched between locked and unlocked simultaneously by operating the operating part 65 on one side of the vehicle in the left-right direction, so that the height of the windscreen 31 can be adjusted stably by the pair of left and right lock operating parts 47L, 47R, and the height of the windscreen 31 can be adjusted with one hand.

[0077] In the windscreen device 30, the lock operating parts 47L, 47R move the engaging members 46L, 46R to the other side in the left-right direction of the vehicle to enter a locked state S1, and move the engaging members 46L, 46R to one side in the left-right direction of the vehicle to enter an unlocked state S2, and the engaging members 46L, 46R are biased to the other side in the left-right direction of the vehicle by an elastic member (coil spring 57). According to this configuration, the engaging members 46L, 46R of the lock operating parts 47L, 47R are biased toward the other side (lock side) of the vehicle in the left-right direction by the coil spring 57, so that after operating the operating part 65 toward one side (unlock side) in the left-right direction of the vehicle to adjust the screen height, the lock operating parts 47L, 47R can be returned to the locked state S1 simply by releasing the operating part 65, making it easier to adjust the height of the windscreen 31.

[0078] In the windscreen device 30, at least one of the first fitting surface (46b) that fits into the fitting recesses 45L, 45R of the fitting members 46L, 46R and the second fitting surface (45b) that fits into the fitting members 46L, 46R in the fitting recesses 45L, 45R is a tapered surface 45b, 46b whose cross-sectional shape narrows toward the other side in the left-right direction of the vehicle. According to this configuration, at least one of the mating surfaces of the mating members 46L, 46R and the mating recesses 45L, 45R is formed as a tapered surface 45b, 46b. Therefore, even if the relative positions of the mating members 46L, 46R and the mating recesses 45L, 45R are slightly misaligned, the tapered surface 45b, 46b can guide the mating members 46L, 46R and the mating recesses 45L, 45R to the specified relative positions. Furthermore, when the mating members 46L, 46R are biased in the mating direction, the wedge effect of the tapered surface 45b, 46b allows the mating members 46L, 46R and the mating recesses 45L, 45R to be securely mated without play, even with a limited biasing force. This further facilitates screen height adjustment.

[0079] In the windscreen device 30, the operating portion 65 includes a grip portion 68 that extends rearward relative to the shaft 53 when viewed in the axial direction of the shaft 53. According to this configuration, the operating unit 65 is provided with a gripping portion 68 that extends rearward from the shaft 53, which makes it easier to see and reach the gripping portion 68 from behind the operating unit 65 (on the passenger side), thereby improving the operability of the operating unit 65.

[0080] In the windscreen device 30, the operating portion 65 includes a grip portion 68 that is offset outward in the left-right direction of the vehicle relative to a base portion 66 to which the end of the shaft 53 is fixed. According to this configuration, the operating unit 65 is provided with a gripping portion 68 that is offset outward in the left-right direction of the vehicle from the end of the shaft 53, which makes it easier to ensure clearance for the hand to reach inside the gripping portion 68 in the left-right direction of the vehicle regardless of the left-right position of the end of the shaft 53, thereby improving the operability of the operating unit 65.

[0081] In the windscreen device 30, the lock operating parts 47L, 47R have a rotation restricting structure 48 that restricts rotation of the operating part 65 about the shaft 53 in the locked state S1. According to this configuration, the lock operating parts 47L, 47R have the rotation restriction structure 48 that restricts the rotation angle of the operation part 65 in the locked state S1, so that the rotation angle of the operation part 65 after the screen height adjustment (locked state S1) can be set to a desired angle that is set in advance. Therefore, the operation part 65 after the screen height adjustment can be maintained at an angle that is easy to hold.

[0082] The present invention is not limited to the above embodiment, and may be configured, for example, such that the holder 50 has a slide groove forming portion and the bracket 40 has a shaft holding portion. The windscreen device 30 of this embodiment may be applied to saddle-ride type vehicles other than motorcycles. The saddle-ride type vehicles include all vehicles on which the driver straddles the body, and include not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (including vehicles with one front wheel and two rear wheels, as well as vehicles with two front wheels and one rear wheel) or four-wheeled vehicles (such as four-wheeled buggies). Furthermore, the saddle-ride type vehicles include not only vehicles with a straddle section, but also vehicles without a straddle section. The configurations in the above-described embodiments are merely examples of the present invention, and various modifications are possible without departing from the spirit of the present invention, such as replacing the components of the embodiments with well-known components.
