[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a windshield adjusting device for motorbikes (motorcycles), bicycles, water bikes, snow bikes, and the like.
[0002]
[Prior art]
Some types of vehicles such as motorbikes that are exposed to the outside use windshields to avoid wind from the front. In such a vehicle, the driver wakes up comfortably during normal driving, and takes a forward leaning posture to avoid wind pressure during high-speed driving. Therefore, conventionally, the projected area from the front of the windshield is increased in order to sufficiently protect the driver in normal driving, and the projected area is decreased in order to reduce air resistance in high-speed driving. Possible windshield adjustment devices have been proposed. In such a windshield adjusting device, the windshield is supported so as to be slidable obliquely up and down, and a slide-type device that is lifted and lowered by a motor drive, and the windshield is rotatably supported by a hinge or a link to adjust the inclination angle. There is a tilt type device.
[0003]
As an example of the former, there is a wind screen device disclosed in Japanese Utility Model Publication No. 62-54887, for example. As shown in FIG. 14, the screen guide 103 supports the lower half side edges of the windscreen (windshield) 102 so as to be movable up and down, the rack 104 provided vertically in the lower center of the back of the screen guide, A drive gear 105 that meshes with the rack, and a reduction gear and a motor M that reciprocally drive the drive gear are provided. This can rotate the motor M, drive the rack 104 meshing with the drive gear 105 up and down, and slide the wind screen 102 up and down according to the driving situation.
[0004]
Japanese Utility Model Laid-Open No. 62-54888 discloses a device for driving the windshield 102 up and down by combining a so-called X link 107 and a crank mechanism 108 as shown in FIG. The X link 107 includes two links 110 and 111 each having a lower end rotatably connected to the vehicle body side and a central portion rotatably connected by a pin 109. A horizontal bar 112 attached to the wind screen 102 is slidably attached to the upper ends of the links 110 and 111. The pin 109 is guided by a guide 113. The crank mechanism 108 includes an eccentric disk 114 that is rotationally driven by a motor, and a crank 115 that connects the eccentric disk 114 and the pin 109.
[0005]
  On the other hand, as a tilt-type device, JP-A-7-32There is a position adjustment apparatus of the 9859 gazette. As shown in FIG. 16, the right and left ends of the windshield 116 are attached to the vehicle body side via two links 117 and 118, respectively. The links 117 and 118 together with the vehicle body and the windshield 116 constitute a so-called four-point link mechanism. The lower left and right links 117 are connected to each other by a shaft 119, and the shaft is connected to a shaft 121 via a worm and gear 120, and the shaft is connected to a speed reducer and a motor M.
[0006]
This can manually tilt the windshield 116 up and down (if the motor M is not provided), and the shaft 119 and the links 117 and 118 rotate counterclockwise when the windshield is moved upward. Further, the tilt angle of the windshield 116 can be freely adjusted by rotating the links 117, 118 counterclockwise by the motor M via the shaft 119.
[0007]
[Problems to be solved by the invention]
In any of the above-described devices, when the motor is driven, the motor M, the speed reducer, the transmission mechanism, and the like are disposed directly under the windshield, and thus it is necessary to devise a technique for avoiding interference with the headlights of the motorcycle. Therefore, it becomes difficult to design, and it is necessary to prepare a different conduction mechanism for each model.
[0008]
It is a technical object of the present invention to provide a windshield adjusting device for a motorcycle or the like that can dispose a drive mechanism such as a motor at a position away from the windshield, thereby making it easy to install and sharing by model. Yes.

  In the adjusting device in which the guide rail is inclined forward and downward, the windshield may be fixed to the slider.
[0016]
[Operation and effect of the invention]
In the adjusting device of the present invention, when the cable driving mechanism is driven to reciprocate the cable, the windshield can be lifted or lowered by the cable. Therefore, it is not necessary to provide the drive mechanism near the windshield. Therefore, the degree of freedom in installing the drive mechanism is greatly improved, such as routing the cable while avoiding headlights and the like. Further, since the cable is guided by a conduit, the degree of freedom of the cable routing route is higher than when guiding by a pulley.
[0017]
  furtherHas guide rails and slidersBecauseThe reciprocating operation of the cable causes the slider to reciprocate along the guide rail, and the windshield can be moved up and down or tilted by the movement. Therefore, even when the windshield tilts, the cable only needs to be reciprocated in a straight line. Therefore, the operation of the cable is simple and the reliability of the operation is increased. In the case of the adjusting device in which the guide rail is curved, the inclination angle of the windshield can be changed in accordance with the elevation of the slider.
[0018]
In the apparatus provided with the two pull cables, when the drum is rotated in one direction, one pull cable is wound around the drum and the other pull cable is sent out. The other end of the one pull cable pulls the slider and moves it along the guide rail. At the same time, the other end of the other pull cable fed from the drum is pulled by the slider. When the drum rotates in the reverse direction, the other pull cable pulls the slider, and one pull cable sent from the drum is pulled by the slider. As described above, in this apparatus, by rotating one drum, the cable can be reciprocated like a closed loop, and the slider can be reciprocated. Moreover, since a pull cable is used, the flexibility of a cable is high and the freedom degree of wiring is still higher.
[0019]
Since the adjustment device using the ring speed reducer as the cable drive mechanism has a large reduction ratio, the cable drive mechanism can be made compact. The adjustment device using the worm reduction gear has a larger reduction ratio, and can be configured more compactly.
[0020]
In an apparatus provided with a cable guide for reversing the direction of the cable at one end of the guide rail, the reversed cable can be routed together with the other cable, so that the wiring space can be reduced. Furthermore, in the device using the cable guide that changes the direction of both cables together in addition to the reversing guide, both cables can be routed together from the guide rail to the cable drive mechanism. .
[0021]
When the cable is a push-pull cable, a return routing route is not required, so that the routing space can be reduced. In particular, when the number of guide rails is one, the installation space for the entire adjusting device can be reduced. In the apparatus using the above-described two guide rails and two push-pull cables that are simultaneously pushed and pulled, the windshield can be stably operated. In addition, in a device that operates two push-pull cables with one gear, since only one drive mechanism is required, it is possible to reliably operate the windshield in a small space.
[0022]

[0023]
1 includes a pair of left and right links 2 and 2 interposed between the windshield 1 and the vehicle body, and a slide guide mechanism 3 for guiding the lower part of the windshield 1 in the vertical direction. The slide guide mechanism 3 includes a guide rail 4 attached to the vehicle body, and a slider (carrier plate) 5 that slides along the guide rail 4. Furthermore, this embodiment includes cables (pull cables) 6 and 7 for pulling and driving the slider 5 upward and downward, respectively, and a motor-driven cable drive mechanism 8 for operating the cables 6 and 7. ing. In this embodiment, both cables 6 and 7 are actually constituted by a single cable continuously in the slider portion. The term “substantially two pull cables” in claim 3 includes one cable having the function of such two cables.
[0024]
The upper end of the guide rail 4 and the cable drive mechanism 8 are connected by a conduit 9 that guides the cable 6 for ascending, and the lower end of the guide rail 4 and the cable drive mechanism 8 are connected by a conduit 10 that guides the cable 7 for descending. Has been. The windshield 1 is shown by a simple rectangular imaginary line for easy understanding, but actually has the same form as a conventional one that is long in the vertical direction. The mounting angle of the guide rail 4 is adjusted to the angle of the tilt position (imaginary line J1) of the windshield 1, but is usually about 20 to 45 degrees, particularly around 30 degrees with respect to the horizontal plane.
[0025]
One end of the link 2 is connected to the vehicle body so as to be rotatable around a horizontal axis S1, and the other end is also rotated around the horizontal axis S2 at the left and right ends of the upper portion of the windshield 1. It is attached freely. The link 2 can be composed of a metal plate or a synthetic resin plate. Further, the attachment position of the link 2 to the vehicle body is usually behind the windshield 1. However, it may be arranged forward. Here, “rearward” means the rear side in the traveling direction of the vehicle body. As shown in FIG. 3, the rotation range of the link 2 is between a descending position P <b> 1 inclined obliquely downward with respect to the guide rail 4 and an ascending position P <b> 2 inclined somewhat upward. The lowered position P1 corresponds to the lower end position of the slider 5, and at that time, the windshield 1 is substantially parallel to the guide rail 4.
[0026]
  Returning to FIG. 1, the guide rail 4 includes a base portion 4 a having a wide width attached to the vehicle body, a pipe portion 4 b through which the inner surface of the guide rail 4 guides the base portion 5 a of the slider 5 slidably and passes the cables 6 and 7. The slider 5 and the flat plate portion 4c that slides. The inside and outside of the pipe portion 4b communicate with each other through a guide groove 4d. The upper end of the guide rail 4 is for raisingNoA semicircular cable guide (reverse guide) 12 for reversing the table 6 downward from the direction along the guide rail is attached. The cable guide 12 includes an arcuate guide groove 13 that is in sliding contact with the cable 6, and a conduit attachment portion 15 to which an end portion of the conduit 9 is attached. The cable guide 12 can be made of synthetic resin or the like.
[0027]
One end of the conduit 9 is attached to the conduit attaching portion 15, the conduit 9 extends downward along the guide rail 4, and the other end is connected to the cable driving mechanism 8. One end of the conduit 10 of the lowering cable 7 is attached to the lower end of the guide rail 4, extends in the extending direction of the guide rail, and the other end is attached to the cable driving mechanism 8.
[0028]
The slider 5 includes a base portion 5a having a T-shaped cross section that is in sliding contact with the guide groove 4d, the inner surface of the pipe portion 4b, and the surface of the flat plate portion 4c, and a rising portion 5b for attachment to the windshield 1. The base 5a is actually provided with a locking portion for locking the middle of one cable 6, 7 (or the end of each of the two cables). A central portion in the vicinity of the lower end of the windshield 1 is rotatably supported by a pin or the like with respect to the rising portion 5b. Therefore, the windshield 1 is supported at three places.
[0029]
The ascending cable 6 extends upward from the base portion 5 b of the slider 5, is turned downward by the cable guide 12, and is passed through the conduit 9. The descending cable 7 extends downward from the base portion 5 b of the slider 5 and is passed through the conduit 10.
[0030]
As shown in FIG. 2, the cable drive mechanism 8 includes a motor M, a speed reducer G, and a drum 16. For example, a multistage type reduction gear in which a ring planetary gear reduction gear is connected in two stages is used as the reduction gear G. However, a worm reduction gear (see FIG. 7) described later may be provided, and a direct reduction without a reduction gear may be provided. The motor M may be connected to the drum 16. A groove for winding the cables 6 and 7 is formed around the drum 16, and a locking portion for locking the cable end is provided. The conduits 9 and 10 are connected to a cover 17 that covers the drum 16.
[0031]
For the cables 6 and 7 and the conduits 9 and 10 described above, the inner cable and the conduit of the pull control cable can be used. Since they are highly flexible, they have a high degree of freedom in routing and are preferable. The cables 6 and 7 are wound around the drum 16 from the opposite direction. When the drum 16 is rotated in one direction, one cable is wound and the other cable is sent out.
[0032]
In the windshield adjusting device A configured as described above, when the slider 5 is lowered as indicated by an imaginary line P1 in FIG. 3, the windshield 1 is also lowered (see the imaginary line J1), and the guide rail 4 It is almost parallel to. From this state, when the motor M of the cable drive mechanism 8 is rotated in one direction, the ascending cable 6 is wound around the drum 16, and the descending cable 7 is sent out from the drum, a loop composed of these cables is one. The slider 5 that circulates in the direction and is engaged with the other ends of the cables 6 and 7 rises along the guide rail 4 (arrow K).
[0033]
Accordingly, the lower part of the windshield 1 connected to the slider 5 also rises along the guide rail 4. At that time, the left and right links 2 and 2 rotate counterclockwise around the central axis S <b> 1 and push up the upper part of the windshield 1 in the direction away from the guide rail 4. This increases the inclination angle of the windshield with respect to the horizontal plane.
[0034]
When the slider 5 rises and the straight line connecting the rotation centers S1 and S2 of the link 2 becomes substantially perpendicular to the guide rail 4, the inclination angle becomes the largest, and beyond that, the inclination angle increases somewhat. (See imaginary line J2.) For example, when the limit switch or the like detects that the slider has reached the rising end, the motor M stops.
[0035]
On the contrary, when the motor M is rotated in the reverse direction from the state where the slider 5 is at the rising end, the loops of the cables 6 and 7 circulate in the reverse direction, and the slider 5 descends along the guide rail 4. Thereby, the inclination angle becomes smaller while the windshield 1 is lowered. Thus, in this adjustment apparatus A, the raising / lowering operation | movement and tilting operation | movement of the windshield 1 can be performed simultaneously.
[0036]
In this adjusting device A, the windshield 1 is normally stopped at the rising end or the falling end, but the slider 5 may be stopped in the middle of the guide rail 4. Regardless of the position at which the slider 5 is stopped, the rotation of the drum 16 is restrained by the reverse rotation preventing action of the reduction gear G, so that it is possible to resist an external force (for example, wind pressure) applied to the windshield 1.
[0037]
Further, the slide guide mechanism 3 including the guide rail 4 and the slider 5 and a drive mechanism (cable drive mechanism 8 in the present embodiment) such as the motor M and the speed reducer G are connected by cables 6 and 7 and conduits 9 and 10. ing. Therefore, the position of the drive mechanism such as the motor M or the speed reducer G can be set relatively freely. For example, it can be arranged at an appropriate position while avoiding a headlight or the like. In that case, the cables 6, 7 and the conduits 9, 10 can be routed around the headlight.
[0038]
Next, another embodiment of the windshield adjusting device of the present invention will be described with reference to FIGS. The windshield adjusting device B of FIG. 4 has basically the same configuration as the adjusting device A described above, except for the slide guide mechanism 3. That is, a pair of left and right links (reference numerals 2 and 2 in FIG. 5) interposed between the windshield 1 and the vehicle body, a slide guide mechanism 3 for guiding the lower part of the windshield 1 in an obliquely vertical direction, and the slide guide mechanism Are provided with cables 6 and 7 for reciprocating up and down, and a motor-driven cable drive mechanism 8 for operating the cables 6 and 7. The guide rail 4 and the cable driving mechanism 8 are connected by conduits 9 and 10 for guiding the cable.
[0039]
The slide guide mechanism 3 includes a guide rail 4 attached to the vehicle body, and a carrier plate (slider) 21 that slides along the guide rail 4. The guide rail 4 includes a main body 22 (see FIG. 6b) obtained by bending a metal plate into a C-shaped cross section, and brackets 23 and 24 fixed to upper and lower ends thereof. The bracket can also be manufactured by pressing a metal plate. A cable guide 25 is attached to the upper bracket 23 to change the direction of the two cables 6 and 7 from the direction along the guide rail to the side.
[0040]
The cable guide 25 has an attachment portion for attachment to the upper bracket 23, arcuate guide portions 26 and 27 (see FIG. 6a) that are in sliding contact with the two cables 6 and 7 for ascending and descending, and a conduit 9, 10 is provided with a conduit attachment portion 28 for attaching the end portions. The cable guide 25 can be made of synthetic resin or the like.
[0041]
A reversing guide 29 having a semicircular guide groove for slidably guiding the lowering cable 7 so as to be reversed is attached to the lower bracket 24. The reversing guide 29 may be provided integrally by insert molding. The upper and lower brackets 23 and 24 are attached with stoppers 30 and 31 made of rubber or the like for defining the rising and falling ends of the carrier plate 21. The motor M of the cable drive mechanism 8 may be stopped by detecting an overcurrent when the carrier plate 21 abuts against the stoppers 30 and 31, and limit switches are provided on the upper and lower brackets 23 and 24. And the motor M may be stopped by detecting the rising end and the falling end of the carrier plate 21.
[0042]
As shown in FIGS. 6 a and 6 b, the carrier plate 21 is a metal plate provided with rising portions 21 a for attachment to the windshield 1 on both sides. The central part near the lower end of the windshield 1 is rotatably supported by a pin or the like with respect to the rising part 21a. Further, a pair of upper and lower guide rollers 32 are rotatably attached to the back side of the carrier plate 21 by a shaft 32a. The guide roller 32 is dimensioned to roll within the main body 22 of the guide rail 4. A slide shoe may be employed instead of the guide roller 32.
[0043]
The rectangular opening 33 formed in the carrier plate 5 is fitted with a locking portion 34 for locking the cable ends 6 a and 7 a of the cables 6 and 7. The locking portion 34 is made of a synthetic resin, and can be manufactured by integrally molding the metal plate constituting the carrier plate by insert molding or by fitting a resin case to the metal plate. The locking portion 34 has a box shape and includes a cavity 34a for accommodating the cable ends 6a and 7a therein. Further, a groove 34b through which the cable passes is formed in the upper and lower end walls. In addition, you may make it the latching | locking part 34 serve as what is called a dog which operates a limit switch.
[0044]
As shown in FIG. 4, one end of the ascending cable 6 is locked to the locking portion 34, extends upward, and is turned sideways by the cable guide 25 and then passed through the conduit 9. . One end of the lowering cable 7 is locked by the locking portion 34, extends downward, changes the direction upward by the reversing guide 29, and further changes the direction by the cable guide 25, and then passes through the conduit 10. Has been.
[0045]
As shown in FIG. 4, the cable drive mechanism 8 includes a motor M, a speed reducer G, and a drum 36. For example, as shown in FIG. 7, the speed reducer G includes a worm 37 connected to the output shaft of the motor M, and a worm wheel 38 concentrically arranged with the drum 36 and connected by a ratchet plate 36a via a shock absorber 38a. The ring planetary gear reducer (see FIG. 2) described above can also be used, and the motor M can be directly connected to the drum 36 without the reducer. As shown in FIG. 8, the shock absorber 38a is an elastic member such as rubber interposed between a fan-shaped space 38b formed on the worm wheel 38 and a fan-shaped protrusion 36b formed on the ratchet plate 36a. Each shock absorber 38a is connected in an annular shape by a ring integrally formed inside. The ratchet plate 36a and the drum 36 are formed with ratchet teeth 36c and 36d as one-way engaging means so as to engage with each other when the windshield is raised, for example. In addition, the code | symbol 38c of FIG. 7 is a spacer.
[0046]
As shown in FIG. 7, a groove for winding the cables 6 and 7 is formed around the drum 36, and a space 39 for locking the cable end is provided. A cylindrical slide member 41 fixed to the ends of the conduits 9 and 10 is inserted into the cover 40 covering the drum 16 so as to be movable in the axial direction. A spring 43 for applying tension to the cable is interposed between the flange portion 42 of the slide member 41 and the housing 40.
[0047]
In the cable drive mechanism 8, when the motor M rotates, the worm 37 rotates and the worm wheel 38 is decelerated to rotate. The rotation is transmitted to the ratchet plate 36a through the shock absorber 38a, and is transmitted to the drum 36 through the ratchet teeth 36c and 36d. Thereby, one cable is wound on the drum 36 and the other cable is sent out from the drum 36. At that time, the shock absorber 38a softens the shock at the start and stop of the rotation of the motor M, and softens the shock at the stop at the upper and lower ends of the slider. Further, the elongation of the cables 6 and 7 that occurs in the initial stage is absorbed by the idle rotation of the ratchet teeth 36c and 36d. The subsequent cable extension is absorbed by the spring 43.
[0048]
The action of the windshield adjusting device B configured as described above is substantially the same as that of the above-described windshield adjusting device A, and the reciprocating rotation of the motor M causes the carrier plate 21 to be tilted forward and lowered. It can be made to stand upright (see FIG. 5). And since the windshield 1 and the drive part are connected by the cables 6 and 7, the freedom degree of arrangement | positioning of a drive part is high. Furthermore, in this embodiment, since the guide roller 32 is provided on the carrier plate 21, the windshield 1 receiving the wind pressure can be raised and lowered smoothly. Moreover, since both the conduits 9 and 10 connect between the cable guide 25 of the upper bracket 23 and the cable driving mechanism 8, the wiring is easier.
[0049]
Next, still another embodiment of the windshield adjusting device of the present invention will be described with reference to FIGS. In the above-described windshield adjusting devices A and B, two pull cables arranged in a loop are substantially used for the windshield lifting / tilting operation. In this windshield adjusting device C, as shown in FIG. As described above, a pair of left and right slide guide mechanisms 3 are provided, and they are driven by the cable driving mechanism 8 via a pair of left and right cables 51, 51. Each cable 51 uses a push-pull control cable inner cable that transmits forces in both push and pull directions. In particular, in this embodiment, a so-called geared cable having a helical tooth on the surface is used. Each cable 51 is guided by guide pipes (conduit) 52 and 52 that connect the slide guide mechanism 3 and the cable drive mechanism, and a guide rail 53 described later.
[0050]
The slide guide mechanism 3 includes a guide rail 53 and a slider 54 that is slidably guided by the guide rail 53. As shown in FIG. 11a, the guide rail 53 has a plate-like base portion 55 and a guide portion 56 protruding thereon. The guide portion 56 has a rectangular cross section, and engagement grooves 57 are formed on the left and right. In addition, it can also be considered that the protrusion 58 protrudes from the upper end of the guide part 56 to the left and right. A guide hole 59 for slidably guiding the cable 51 is formed at the center of the guide portion 56, and the guide hole communicates with the outside by a groove 61 opened on the surface 60 of the guide portion.
[0051]
The slider 54 includes left and right leg portions 62 that are in sliding contact with the surface 60 of the guide portion 56, and a support portion 63 that is connected to the windshield by pins or the like. Engagement pieces 64 that engage with the engagement grooves 57 of the guide portion 56 are provided on the left and right of the upper and lower ends of the leg portion 62. A fitting hole 66 is formed in the center of the lower surface of the slider 54 to fit the cylindrical pin 68 of the connecting member 65 fixed to the cable 51. As shown in FIG. 11b, the connecting member 65 includes a fixing portion 67 fixed to the cable 51 by caulking or the like, the above-described pin 68, and a connecting portion 69 that connects the two through the groove 61 of the guide rail. Yes. An annular spacer 54a for smoothly sliding the connecting portion 69 is interposed between the slider 54 and the surface 60 of the guide rail. Note that reference numeral 55 a in FIG. 11 a is a stopper that defines the upper and lower stroke ends of the slider 54.
[0052]
Returning to FIG. 9, the end of the guide pipe 52 is connected to the lower end of each guide rail 53 so as to extend the guide hole 59. The inner surface of the guide pipe 52 and the inner surface of the guide hole 59 are smoothly connected so as to be flush with each other. The guide pipe 52 connected to the right guide rail 53 in FIG. 9 extends downward, and then curves to the left and is connected to the cable drive mechanism 8. The guide pipe 52 connected to the left guide rail 53 extends downward, curves to the right, and is connected to the cable drive mechanism 8 from the opposite side.
[0053]
The cable drive mechanism 8 includes a motor M, a speed reducer G, a gear 70 connected to the output shaft of the speed reducer, and a cable guide portion 71 that guides the cable 51 coming out of the guide pipe 52. Yes. The speed reducer G is preferably a speed reducer having a self-restraining property such as a worm speed reducer, but may be directly connected from the motor M to the gear 70 without the speed reducer. A guide hole 72 for guiding the two cables 51 in parallel with each other is provided in the cable guide portion 71 so as to pass through both sides of the gear 70, and the guide holes are opened at both side portions of the gear 70. The gear 70 meshes with the helical teeth of the cable 51. Further, a guide pipe 73 that guides the distal end portion of the cable 51 is connected to the end portion of the guide hole 72 of the cable guide portion 71.
[0054]
In the adjusting device C configured as described above, when the motor M rotates in one direction, the gear 70 rotates in one direction via the speed reducer G. As a result, the left and right cables 51, 51 that are engaged with both sides of the gear 70 are synchronously driven to the opposite sides, and are driven in the same direction in the guide rails 53, 53. Thereby, the slider 54 connected to the left and right cables 51 is synchronized and, for example, ascends. As a result, the lower portion of the windshield 1 ascends as indicated by an arrow K in FIG. 10, and the link 2 rotates counterclockwise. Thereby, the upper part of the windshield 1 moves away from the guide rail, and the windshield 1 tilts clockwise while rising.
[0055]
When the motor M rotates in the reverse direction, the cables 51 in the left and right guide rails descend in synchronization, and the slider 54 also descends. As a result, the lower part of the windshield 1 is lowered and the link 2 is rotated counterclockwise. Therefore, the windshield 1 descends while tilting counterclockwise.
[0056]
As described above, also in the windshield adjusting device C, the windshield is moved up and down and tilted simultaneously, and the drive mechanism can be installed at a position away from the windshield. However, since the guide pipe 52 of the push-pull control cable is thicker and more rigid than the pull cable conduit, the routing position is less flexible than in the case of the pull cable. However, the adjusting device of the type that supports the windshield with the above two guide rails supports the windshield at four places, top, bottom, left, and right, so that it is resistant to the wind pressure applied to the windshield, particularly the wind pressure that tries to twist the windshield. There are strong advantages. Also, since the cable does not need to be routed in a loop, the area around the guide rail is simplified.
[0057]
In the embodiment of FIG. 9, two guide rails and two push-pull cables (geared cables) are used, but they can be driven by one guide rail and push-pull cable. In that case, it is preferable to drive the central portion of the lower part of the windshield 1 as shown in FIG. When a single push-pull cable is used, the installation space can be further reduced.
[0058]
Moreover, it can replace with the cable drive mechanism 8 provided with the ring planetary gear speed reducer used for the adjustment apparatus A of FIG. 1, and the cable drive mechanism 8 using the worm speed reducer of FIG. 7 is employable. Conversely, the cable drive mechanism 8 of the adjusting device A shown in FIG. 1 can be employed in the adjusting device B shown in FIG.
[0059]
In the above embodiment, the cable driving mechanism is driven by a motor, but the cable may be driven by means such as a crank handle. In this case, the windshield angle and elevation can be operated simultaneously. In each of the above-described embodiments, a part of the windshield is guided by a slide guide mechanism including a guide rail and a slider or a carrier plate so as to move linearly, and the guided part is reciprocated straight by a cable. Driving. Therefore, the drive by a cable can be performed stably. However, the device of the present invention (Claim 1) is not limited to itself. For example, the windshield may be attached so as to be rotatable about a horizontal axis, and the end of the cable may be directly connected to the windshield. Even in such a case, the cable drive mechanism can be arranged at a position apart from the headlight.
[0060]
In the above-described embodiment, the lower part of the windshield is guided by a slide guide mechanism so as to be able to reciprocate linearly, and the upper part is connected to the vehicle body by a link. However, the lower part of the windshield may be connected by a link, and the upper part may be guided by a slide guide mechanism. Further, as shown in FIG. 12a, the guide can be linearly guided by a guide mechanism including the guide rail 4 and the slider 5 without using a link. In this case, in order to stabilize the attitude of the windshield, it is preferable to provide a roller 32 or a sliding member that rolls or slides with the guide rail 4 at two upper and lower positions. The windshield 1 does not tilt, but simply moves up and down along the guide rail 4. However, even in that case, there is an effect that the mounting position of the drive mechanism such as a motor can be freely set.
[0061]
Further, as shown in FIG. 12b, the guide rail 4 may be curved in an arc shape in the front-rear direction (vertical direction) so as to protrude downward (backward). In that case, the inclination angle of the windshield changes according to the position of the windshield 1. When driven by a cable having flexibility, even when such a guide rail 4 is curved, it can be driven relatively smoothly. The guide rail 4 may be curved so as to protrude upward (forward).
[0062]
FIGS. 13 a and 13 b show an embodiment in which the curved guide rail 4 and link 3 are combined. In these cases, the slider 5 and the windshield 1 are rotatably connected. In the case of these adjusting devices, the tilt angle can be increased (in the case of FIG. 13b), or conversely, the tilt angle can be decreased (in the case of FIG. If).
[0063]
Further, as shown in FIG. 13c, two guide rails 4, 4 may be provided on the upper and lower sides (four when arranged on the left and right), and an angle may be provided therebetween. Even in this case, the lifting and tilting operations can be performed simultaneously.
