Description

[Technical Field]

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

[0002] Patent Document 1 discloses a windshield device for a saddle-ride type vehicle. The windshield device has a fixed member fixed to the vehicle body, a screen, a holding member that supports the screen, and front and rear links that connect the holding member and the fixed member. The holding member, fixed member, front link, and rear link cooperate to form a four-bar link. As the front link and rear link rotate, the holding member and screen move relative to the fixed member.

[0003] The rear link has left and right arm portions rotatably supported on the fixed member. The rear link is provided with a locking mechanism that restricts rotation of the rear link relative to the fixed member. The locking mechanism includes a shaft that extends left and right and penetrates the left and right arm portions and the fixed member, left and right gears fixed to the shaft, a first engagement hole formed in the left arm portion, a second engagement portion formed in a left portion of the fixed member, a third engagement hole formed in the right arm portion, a fourth engagement portion formed in a right portion of the fixed member, an operating portion provided at the left end of the shaft, and a spring that biases the shaft leftward. When the shaft is moved to the left in a locked state, the left gear engages with the first and second engagement holes, and the right gear engages with the third and fourth engagement holes, thereby restricting rotation of the rear link relative to the fixed member. In the released state where the shaft has moved to the right, the left gear disengages from the first and second engagement holes, and the right gear disengages from the third and fourth engagement holes, allowing the rear link to rotate relative to the fixed member.

[0004] [Patent Document 1] Patent No. 6367263 specification Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the configuration of Patent Document 1, if manufacturing errors or deformation occur in any of the fixing member, holding member, rear link, shaft, or gear, a problem occurs in that, in the locked state, the left gear cannot fit tightly into the first and second engagement holes, or the right gear cannot fit tightly into the third and fourth engagement holes, which results in rattles in the rear link, holding member, and screen, making it impossible to keep the screen in a stable position.

[0006] In view of the above background, an object of the present invention is to provide a windshield device that can keep the position of the screen constant. [Means for solving the problem]

[0007] In order to solve the above problem, one aspect of the present invention is a windshield device (1) having a first guide hole (16) and a second guide hole (17) spaced apart on the left and right, a fixed member (4) fixed to a vehicle body (3), a shaft (5) extending in the left-right direction and movably inserted into the first guide hole and the second guide hole, a retaining member (6) supported by the shaft, and a screen (7) supported by the retaining member, wherein a plurality of first lock holes (31) are provided in the first guide hole, and a plurality of second lock holes (32) are provided in the second guide hole at positions corresponding to the first lock holes in the left-right direction, a first fitting portion (35) that can be fitted into the first lock hole is fixed to the shaft, and a second fitting portion (36) that can be fitted into the second lock hole is supported on the shaft so as to be movable within a predetermined range in the axial direction of the shaft.

[0008] According to this aspect, the second fitting portion is supported so as to be movable within a predetermined range in the axial direction of the shaft, so that even if manufacturing errors or deformation occur in the windshield device, the second fitting portion can move relative to the shaft, allowing the first fitting portion to fit into the first lock hole and the second fitting portion to fit into the second lock hole. This makes it possible to provide a windshield device that can keep the position of the screen constant.

[0009] In the above aspect, the fitting allowance (L1) of the first fitting portion with respect to the first lock hole may be set to be larger than the sum of the fitting allowance (L2) of the second fitting portion with respect to the second lock hole and the play length (L3) in the release direction between the second fitting portion and the shaft when the second fitting portion is fitted into the second lock hole.

[0010] According to this aspect, when the first fitting portion is disengaged from the first lock hole, the second fitting portion, which is movable relative to the shaft, can be reliably disengaged from the second lock hole. [Effects of the Invention]

[0011] According to the above configuration, it is possible to provide a windshield device that can keep the position of the screen constant. [Brief explanation of the drawings]

[0013] An embodiment in which a windshield device is applied to a motorcycle will be described. As shown in Fig. 1, windshield device 1 is provided at the front of a body 3 of motorcycle 2, which is, for example, a saddle-ride type vehicle. Windshield device 1 is placed in front of the rider and reduces the amount of wind hitting the rider while riding.

[0014] As shown in Figures 1 and 2, the windshield device 1 has a bracket 4 as a fixing member fixed to the vehicle body 3, a shaft 5 supported by the bracket 4, a holder 6 as a holding member supported by the shaft 5, and a screen 7 supported by the holder 6.

[0015] 2 to 5, the bracket 4 has a bracket lower portion 11, a left guide portion 12 and a right guide portion 13 extending upward and rearward from the rear end of the bracket lower portion 11, and a connecting portion 14 extending left and right and joined to the rear ends of the left guide portion 12 and the right guide portion 13. The bracket lower portion 11 has a lower wall portion 11A whose surface faces upward, left and right side wall portions 11B extending upward from the left and right ends of the lower plate, and a rear wall portion 11C extending upward from the rear end of the lower wall portion 11A and joined to the left and right side wall portions 11B.

[0016] The bracket 4 has a left guide hole 16 (first guide hole) and a right guide hole 17 (second guide hole) arranged at a distance from each other on the left and right sides. The left guide hole 16 is formed in the left guide portion 12, and the right guide hole 17 is formed in the right guide portion 13. The left guide hole 16 penetrates the left guide portion 12 in the left-right direction and extends in the up-down direction along the left guide portion 12. The right guide hole 17 penetrates the right guide portion 13 in the left-right direction and extends in the up-down direction along the right guide portion 13. When viewed from the left-right direction, the left guide hole 16 and the right guide hole 17 overlap each other. It is preferable that the left guide hole 16 and the right guide hole 17 are curved so as to be convex forward and upward. In other words, the upper ends of the left guide hole 16 and the right guide hole 17 are located rearward of the lower ends of the left guide hole 16 and the right guide hole 17.

[0017] The shaft 5 extends in the left-right direction and is movably inserted into the left guide hole 16 and the right guide hole 17. The shaft 5 is movable in the direction in which it extends within the left guide hole 16 and the right guide hole 17, i.e., in the up-down direction. The shaft 5 is also movable in the axial direction of the shaft 5, i.e., in the left-right direction.

[0018] The holder 6 has a plate-shaped holder body 6A with its face facing forward, left and right upper arms 6B protruding rearward from the upper end of the holder body 6A, left and right lower arms 6C protruding downward from the lower end of the holder body 6A, and multiple lateral arms 6D protruding laterally to the left and right from the left and right side edges of the holder body 6A.

[0019] The left and right upper arms 6B are arranged apart from each other on the left and right. The tips of the left and right upper arms 6B are connected by an upper reinforcing beam 6E extending in the left-right direction. The upper reinforcing beam 6E improves the rigidity of the left and right upper arms 6B. An upper support hole 21 is formed in each upper arm 6B, penetrating in the left-right direction. The upper support holes 21 are arranged coaxially.

[0020] 6 and 7, each upper support hole 21 has a small diameter portion 21A located on the left side, a large diameter portion 21B located on the right side, and a shoulder surface 21C facing right and located between the small diameter portion 21A and the large diameter portion 21B. The small diameter portion 21A opens onto the left side surface of the upper arm 6B, and the large diameter portion 21B opens onto the right side surface of the upper arm 6B. The diameter of the large diameter portion 21B is set to be larger than the diameter of the small diameter portion 21A. The small diameter portion 21A and the large diameter portion 21B are arranged coaxially with each other.

[0021] The left and right upper arms 6B are disposed between the left guide portion 12 and the right guide portion 13. A shaft 5 is inserted through each upper support hole 21. This allows the holder 6 to be rotatably supported by the shaft 5. The outer circumferential surface of the shaft 5 is in sliding contact with the inner circumferential surfaces of the left and right small diameter portions 21A. A gap is formed between the outer circumferential surface of the shaft 5 and the inner circumferential surfaces of the left and right large diameter portions 21B.

[0022] As shown in Fig. 5, the left and right lower arms 6C are arranged apart from each other on the left and right. The tips of the left and right lower arms 6C are connected by a lower reinforcing beam 6F extending in the left-right direction. The lower reinforcing beam 6F improves the rigidity of the left and right lower arms 6C.

[0023] As shown in Figures 3 to 5, the left and right lower arms 6C are connected to the bracket lower part 11 via links 23. The links 23 are formed in a rectangular frame shape. A first support shaft 24 extending laterally is hung between the left and right lower arms 6C. A second support shaft 25 extending laterally is hung between the left and right side wall parts 11B of the bracket lower part 11. One end of the link 23 is supported by the first support shaft 24. As a result, the link 23 is connected to the holder 6 so as to be rotatable about the first support shaft 24. The other end of the link 23 is supported by the second support shaft 25. As a result, the link 23 is connected to the bracket lower part 11 so as to be rotatable about the second support shaft 25.

[0024] 4, a C-ring 26 is coupled to each of the first support shaft 24 and the second support shaft 25. Each C-ring 26 is coupled to the first support shaft 24 and the second support shaft 25 so as to be immovable in the left-right direction, and fits into a recess formed in the link 23. The C-ring 26 prevents the first support shaft 24 and the second support shaft 25 from falling off the link 23 in the left-right direction.

[0025] 2 and 3, a groove 27 is formed on the left side surface of the left guide part 12. The groove 27 is recessed to the right and extends along the left guide hole 16. The groove 27 forms the left part of the left guide hole 16. The width of the groove 27 is formed to be larger than the width of the left guide hole 16. The groove 27 has a bottom surface 27A facing left.

[0026] As shown in Figures 3 and 6, the left guide hole 16 is provided with a plurality of left lock holes 31 (first lock holes). In this embodiment, the plurality of left lock holes 31 are provided at intervals from one another in the extending direction of the left guide hole 16. Each left lock hole 31 extends rightward from the bottom surface 27A of the groove portion 27. Each left lock hole 31 is a conical hole whose diameter decreases toward the right. Each left lock hole 31 may be a through hole or a recessed portion with a bottom. When viewed from the left-right direction, each left lock hole 31 is arranged to overlap with the left guide hole 16. The diameter of the left end of each left lock hole 31 is larger than the width of the left guide hole 16.

[0027] As shown in FIGS. 4 and 6 , the right guide hole 17 is provided with a plurality of right lock holes 32 (second lock holes). In this embodiment, the multiple right lock holes 32 are provided at intervals in the extension direction of the right guide hole 17. Each right lock hole 32 extends rightward from the left side surface of the right guide portion 13. Each right lock hole 32 is a conical hole whose diameter decreases toward the right. Each right lock hole 32 may be a through hole or a bottomed recess. When viewed in the left-right direction, each right lock hole 32 is arranged to overlap with the right guide hole 17. The diameter of the left end of each right lock hole 32 is larger than the width of the right guide hole 17. Each right lock hole 32 is provided at a position corresponding to the left lock hole in the left-right direction.

[0028] 5 and 6, an operating portion 34 to be gripped by a user is provided at the left end of the shaft 5. The shaft 5 also has a left fitting portion 35 (first fitting portion) that can be fitted into the left lock hole 31, and a right fitting portion 36 (second fitting portion) that can be fitted into the right lock hole 32.

[0029] The left fitting portion 35 is fixed to the shaft 5. That is, the left fitting portion 35 is connected to the shaft 5 so as to be non-rotatable and non-displaceable in the axial direction of the shaft 5. The left fitting portion 35 is disposed to the right of the operating portion 34 and inside the left guide portion 12. As shown in FIG. 8 , in this embodiment, the left fitting portion 35 and the operating portion 34 are integrally formed. The left fitting portion 35 is a cylindrical body having a conical surface 35A on its outer periphery. The shaft 5 is inserted through the center of the left fitting portion 35. The shaft 5 may be press-fitted into the center of the left fitting portion 35. The conical surface 35A of the left fitting portion 35 is provided at the right end of the left fitting portion 35, and its radius decreases toward the right.

[0030] As shown in Figures 6 and 7, the right fitting portion 36 is supported on the shaft 5 so as to be movable within a predetermined range in the axial direction of the shaft 5. The right fitting portion 36 is disposed within the large-diameter portion 21B of the right upper arm 6B. As shown in Figure 9, the right fitting portion 36 has a cylindrical portion 36A and a conical surface 36B formed on the outer periphery of the right end of the cylindrical portion 36A. The shaft 5 is slidably inserted through the center of the right fitting portion 36. The conical surface 36B of the right fitting portion 36 has a radius that decreases toward the right. As shown in Figures 6 and 7, the cylindrical portion 36A is provided with a locking claw 36C that protrudes inward. An annular locking groove 5A extending circumferentially is formed on the outer periphery of the shaft 5. The locking claw 36C protrudes into the locking groove 5A. The locking claw 36C is movable left and right between the left and right end walls of the locking groove 5A. That is, the locking claw 36C abuts against the left end wall or the right end wall of the locking groove 5A, thereby restricting within a predetermined range the left-right movement of the right fitting portion 36 relative to the shaft 5. An outwardly protruding flange portion 36D is provided on the outer periphery of the cylindrical portion 36A.

[0031] As shown in FIG. 6 , the shaft 5 is biased rightward by a first biasing member 41. A retainer 42 is fixed to the shaft 5. The first biasing member 41 is preferably a compression coil spring. The first biasing member 41 is disposed in the large diameter portion 21B of the left upper support hole 21. The first biasing member 41 is preferably supported on the outer periphery of the shaft 5. The left end of the first biasing member 41 abuts against the shoulder surface 21C of the left upper support hole 21, and the right end of the first biasing member 41 abuts against the retainer 42.

[0032] The right fitting portion 36 is biased rightward by a second biasing member 44. The second biasing member 44 is preferably a compression coil spring. The second biasing member 44 is disposed in the large diameter portion 21B of the right upper support hole 21. The second biasing member 44 is preferably supported on the outer periphery of the shaft 5. The left end of the second biasing member 44 abuts against the shoulder surface 21C of the right upper support hole 21, and the right end of the second biasing member 44 abuts against the flange portion 36D of the right fitting portion 36.

[0033] When the shaft 5 passes through one of the left lock holes 31, the left fitting portion 35 can fit into the left lock hole 31, and the right fitting portion 36 can fit into the right lock hole 32. When the shaft 5 moves in the locking direction, which is to the right, the left fitting portion 35 fits into the left lock hole 31, and the right fitting portion 36 fits into the right lock hole 32. This prevents the shaft 5 from moving relative to the left guide hole 16 and the right guide hole 17. This state is called the locked state of the windshield device 1.

[0034] As shown in Figure 7, when the shaft 5 moves in the release direction, which is the left direction opposite to the lock direction, the left fitting portion 35 disengages from the left lock hole 31, and the right fitting portion 36 disengages from the right lock hole 32. This allows the shaft 5 to move relative to the left guide hole 16 and the right guide hole 17. In other words, the shaft 5 can move up and down along the left guide hole 16 and the right guide hole 17. This state is called the release state of the windshield device 1.

[0035] Because the first biasing member 41 biases the shaft 5 in the locking direction relative to the bracket 4, when the windshield device 1 is in the locked state, the left fitting portion 35 is maintained fitted in the left lock hole 31. In addition, because the second biasing member 44 biases the right fitting portion 36 in the locking direction relative to the bracket 4, when the windshield device 1 is in the locked state, the right fitting portion 36 is maintained fitted in the right lock hole 32.

[0036] As shown in Figures 2, 4, and 6, a cover 45 is attached to the center of the shaft 5 in the longitudinal direction. The cover 45 is disposed between the left and right upper arms 6B. The cover 45 is made of a resin material. The cover 45 covers the outer surface of the shaft 5 between the left and right upper arms 6B, and suppresses light reflection by the outer surface of the shaft 5. The cover 45 is formed into a cylindrical shape by combining two members. It is preferable that a protrusion provided on the inner surface of the cover 45 engages with a recess formed on the outer surface of the shaft 5, thereby restricting movement of the cover 45 relative to the shaft 5.

[0037] As shown in FIG. 5, a third biasing member 47 is provided between the holder 6 and the link 23 to bias the link 23 toward the holder 6. The third biasing member 47 is preferably a torsion coil spring and is supported on the first support shaft 24. The third biasing member 47 biases the link 23 toward the holder 6 in one rotational direction around the first support shaft 24, thereby suppressing rattles between the bracket 4 and the link 23 and between the holder 6 and the link 23. The third biasing member 47 preferably biases the link 23 toward the holder 6 in a direction that raises the holder 6. This makes it possible to prevent the holder 6 and the screen from descending under their own weight when the windshield device 1 is in the released state.

[0038] As shown in Figures 8 and 10, an intermediate portion 51 is provided between the operating portion 34 and the left fitting portion 35. The intermediate portion 51 is a cylindrical body that protrudes to the right from the operating portion 34 and is disposed around the shaft 5. The left fitting portion 35 protrudes to the right from the right end of the intermediate portion 51. When the left fitting portion 35 is fitted into the left lock hole 31, the intermediate portion 51 protrudes into the groove portion 27 of the left guide hole 16. A plurality of protrusions 27C are formed on the side wall 27B of the groove portion 27. When the left fitting portion 35 is fitted into the left lock hole 31, the intermediate portion 51 abuts against at least two protrusions 27C, thereby restricting rotation of the intermediate portion 51 and the operating portion 34 about the axis of the shaft 5.

[0039] 3, the bracket 4 has a plurality of fastening portions 4A. The plurality of fastening portions 4A are fastened to the vehicle body 3 by fasteners such as bolts and nuts. The fastening portions 4A may be provided, for example, on the lower surface of the lower wall portion 11A, the lower and upper ends of the left guide portion 12, and the lower and upper ends of the right guide portion 13.

[0040] The operation and effect of the windshield device 1 according to the above embodiment will be described. The position of the shaft 5 is determined by fitting the left fitting portion 35 into one of the multiple left lock holes 31 and fitting the right fitting portion 36 into the corresponding right lock hole 32. This determines the position of the rear end of the holder 6, which is rotatably supported on the shaft 5. At this time, the link 23 rotates, and the position of the front end of the holder 6 is determined according to the position of the rear end of the holder 6. The first biasing member 41 biases the shaft 5 rightward, and the second biasing member 44 biases the shaft 5 rightward, so that the left fitting portion 35 is maintained in a state fitted into the left lock hole 31 and the right fitting portion 36 is maintained in a state fitted into the right lock hole 32. This maintains the positions of the holder 6 and the screen 7.

[0041] The user can change the position and angle of the screen 7 by pulling the operating unit 34 to the left. Because the operating unit 34 is located at the left end of the shaft 5, a user riding a motorcycle can operate the operating unit 34 with only their left hand without releasing their right hand from the accelerator. When the user pulls the operating unit 34 to the left against the biasing forces of the first biasing member 41 and the second biasing member 44, the left fitting portion 35 disengages from the left lock hole 31, and the right fitting portion 36 disengages from the right lock hole 32. This puts the windshield device 1 in a released state, allowing the shaft 5 to move relative to the left guide hole 16 and the right guide hole 17. As shown in FIGS. 11 and 12 , the user can move the shaft 5 along the left guide hole 16 and position the shaft 5 in the other left lock hole 31. At this time, the link 23 rotates in accordance with the position of the shaft 5, thereby determining the position and angle of the holder 6. When the user reduces the force pulling the operating portion 34 to the left, the biasing force of the first biasing member 41 and the second biasing member 44 causes the left mating portion 35 to fit into the opposing left lock hole 31, and the right mating portion 36 to fit into the corresponding right lock hole 32.

[0042] Because the right fitting portion 36 is supported so as to be movable within a predetermined range in the axial direction of the shaft 5, even if manufacturing errors or deformation occur in the windshield device 1, the right fitting portion 36 can move relative to the shaft 5, so that the left fitting portion 35 fits into the left lock hole 31 and the right fitting portion 36 fits into the right lock hole 32. This makes it possible to provide a windshield device 1 that can keep the position of the screen 7 constant. Furthermore, because the left fitting portion 35 fits securely into the left lock hole 31 and the right fitting portion 36 fits securely into the right lock hole 32, rattle of the holder 6 and the screen 7 can be suppressed.

[0043] The first biasing member 41 biases the shaft 5 rightward relative to the bracket 4, so that the left fitting portion 35 fixed to the shaft 5 can be securely fitted into the left lock hole 31. The second biasing member 44 biases the left fitting portion 35 rightward relative to the bracket 4, so that the right fitting portion 36 can be securely fitted into the right lock hole 32.

[0044] The left fitting portion 35 and the right fitting portion 36 are each a conical cylinder, and the left lock hole 31 and the right lock hole 32 are each a conical through-hole. Therefore, the left fitting portion 35 can be smoothly fitted into the left lock hole 31, and the right fitting portion 36 can be smoothly fitted into the right lock hole 32.

[0045] The fitting allowance L1 of the left fitting portion 35 with respect to the left lock hole 31 is set to be larger than the sum of the fitting allowance L2 of the right fitting portion 36 with respect to the right lock hole 32 and the length of play L3 in the release direction between the right fitting portion 36 and the shaft 5 when the right fitting portion 36 is fitted into the right lock hole 32 (L1 > L2 + L3). The fitting allowance L1 of the left fitting portion 35 with respect to the left lock hole 31 is the length of insertion of the left fitting portion 35 into the left lock hole 31 in the left-right direction. The fitting allowance L2 of the right fitting portion 36 with respect to the right lock hole 32 is the length of insertion of the right fitting portion 36 into the right lock hole 32 in the left-right direction. When the right fitting portion 36 is fitted into the right lock hole 32, the locking claw 36C of the right fitting portion 36 is located in the middle portion 51 of the locking groove 5A in the left-right direction. Therefore, even if the shaft 5 moves in the release direction from the locked state, the right fitting portion 36 remains fitted in the right lock hole 32 until the right end of the locking groove 5A abuts against the locking pawl 36C. When the right fitting portion 36 is fitted in the right lock hole 32, the distance between the locking pawl 36C of the right fitting portion 36 and the right end of the locking groove 5A is the play length L3.

[0046] When the shaft 5 moves leftward from the locked state, the right fitting portion 36 does not move relative to the right lock hole 32 until the shaft 5 moves leftward a distance L3. When the movement amount of the shaft 5 becomes greater than the distance L3, the right end of the locking groove 5A pushes the locking pawl 36C of the right fitting portion 36 leftward, causing the right fitting portion 36 to move leftward relative to the right lock hole 32. When the movement amount of the shaft 5 exceeds L2 + L3, the right end of the right fitting portion 36 is positioned leftward of the left end of the right lock hole 32. In other words, the right fitting portion 36 comes out of the right lock hole 32. At this time, the right end of the left fitting portion 35 is still positioned inside the left lock hole 31. When the movement amount of the shaft 5 exceeds L1, the left end of the left fitting portion 35 is positioned leftward of the left end of the left lock hole 31. In other words, the left fitting portion 35 comes out of the left lock hole 31. According to this embodiment, when the left fitting portion 35 is disengaged from the left lock hole 31 , the right fitting portion 36 , which is movable relative to the shaft 5 , can be reliably disengaged from the right lock hole 32 .

[0047] Although the description of the specific embodiment has been completed above, the present invention is not limited to the above embodiment and can be widely modified and implemented. For example, the windshield device 1 may be applied to other types of motorcycles 2, such as types with low floors and no straddle section, or three-wheeled types, as well as other saddle-ride vehicles such as snowmobiles and jet skis. The windshield device 1 may also be applied to various vehicles other than saddle-ride vehicles, such as automobiles and kick scooters. Furthermore, the entire configuration of the windshield device 1 may be reversed left and right.
