Provided Embodiments of the present invention will be described below with reference to the drawings.

  1 to 7 are drawings showing the configuration of this embodiment. FIG. 1 shows a two-wheeled vehicle 101 to which a two-wheeled vehicle stand 100 of this embodiment is attached. As is well known, the two-wheeled vehicle 101 includes a vehicle body 1, a front wheel 2, a rear wheel 3, a drive unit 5 provided with a pedal 4, a handle 6, a handle column 7, a front wheel fork 8, a saddle 9 and a car 10.

  The front wheel 2 is attached to the front end of the front wheel fork 8 via the axle 11 of the front wheel 2. The same applies to the rear wheel 3. Both the front wheel 2 and the rear wheel 3 have forks 26.

  In the present embodiment, a motorcycle stand 100 is attached via the axle 11 of the front wheel 2. A “rotary shaft” is used to distinguish from the axle 11 of the front wheel 2. Therefore, the rotating shaft refers to a rotating portion (means) configured as one part of a two-wheeled vehicle stand regardless of whether or not it is integrated with the axle 11.

  A motorcycle stand 100 having a rotating shaft is attached to the axle 11 as will be described in detail later. As shown in the figure, the motorcycle stand 100 includes a fixing plate 21, a parking arm 22, an operation lever 23, and a wire 25 that are fixing members. In the illustrated case, the operation lever 23 is attached to the handle 6, but may be provided on a part of the vehicle body 1 within the reach of the hand, for example, the handle column 7. In the illustrated case, the two-wheeled vehicle stand 100 is a front wheel, but may be a rear wheel. In the following, description will be made taking front wheel installation as an example.

  FIG. 2 is a side view showing the details of the motorcycle stand 100 from the side, FIG. 3 is an elevation view from the rear, and the motorcycle itself is schematically shown.

  2 and 3, the motorcycle stand 100 has a rotating shaft 30 integrated with the axle 11. Gears 31 as first gears are provided on both sides of the rotating shaft 30. Hereinafter, the motorcycle stand 100 provided on one side will be described, but the structure on the other side is the same and should be analogized. Here, only one side will be mainly described.

  A fixed plate 21 that is a fixed member is attached to the tip of the rotating shaft 30 so as to extend in the direction of the road surface 102. The fixed plate 21 is formed of a single plate including a vertical flat plate portion 36 and an inclined plate portion 37 that is inclined outwardly toward the road surface 102 and inclined forward toward the spoke 26. A parking arm rotation shaft 38 is fixed to the vertical flat plate portion 36 near the inclined plate portion 37, and a gear 32 as a second gear is fixed to the parking arm rotation shaft 38. The parking arm 22 is attached to the parking arm rotation shaft 38. Therefore, when the gear 32 rotates, the parking arm rotation shaft 38 rotates, and the parking arm 22 rotates with this rotation.

  An intermediate gear 33 is provided in the gap between the gear 31 and the gear 32 so as to mesh with both gears and move away from the gear 31 in the direction of the rotation axis. Accordingly, when the intermediate gear 33 is controlled so as to be interposed between the gear 31 and the gear 32 and meshed with both the gears 31, 32, the rotational force of the gear 31 is transmitted to the gear 32 via the intermediate gear 33, and further. The bicycle parking arm 22 is transmitted to the bicycle parking arm 22 via the bicycle parking arm rotation shaft 32, and the bicycle parking arm 22 rotates. The gear 33 is thicker than the gear 31 and always meshes with the intermediate gear 33. As will be described later, the intermediate gear 33 is moved in the direction of the rotation axis by the gear coupling mechanism coupled to the wire 25 that is loosely operated by the operation of the operation lever 23, and is engaged with or separated from both the gears 31 and 32. Become.

  Thus, the first gear 31 attached to the rotary shaft 30 that rotates integrally with the axle 11 of the front wheel 2 so as to rotate together with the rotary shaft 30 and the rotational force of the first gear rotate, Rotational force is transmitted by the second gear 32 that transmits the rotational force accompanying the rotation as the rotational force of the parking arm 22 and the intermediate gear 33 that engages and disengages the first gear 31 by the looseness of the wire 25. The device will be configured. As shown in FIGS. 2 and 3, the gear 32 and the rotation center, that is, the rotation center of the parking arm 22 and the rotation center of the front wheel 2, that is, the rotation center of the rotation shaft 30 (or the axle 11) are eccentric. . That is, the rotation center of the parking arm 22 is set at a position eccentric to the lower side of the road surface with respect to the rotation center of the front wheel 2 (axle 11).

  The parking arm 22 has a tip portion positioned within the peripheral edge of the front wheel 2 in the front horizontal direction of the front wheel 2 and a tip portion positioned below the peripheral edge of the front wheel 2 in the lower vertical direction in the road surface direction. Even if the lower vertical direction exceeds a certain range (angle α °), the tip portion has a length exceeding the peripheral end as shown in FIG.

  The inclined plate portion 37 is formed with an inclined surface parallel to the inclined surface of the inclined plate portion 37, a gap is placed between the inclined plate portion 37, the rotation of the parking arm 22 is allowed, and the outer side A restraint plate 39 is provided to restrain so as not to jump out. A parking arm spring 43, which is a compression spring, is suspended between a spring receiver 41 protruding outward from the vertical flat plate portion 36 and a spring receiver 42 provided on the arm 22. As shown in FIG. 2, the spring receiver 41 is located behind the straight line connecting the rotary shaft 30 and the parking arm rotary shaft 38.

  The parking arm 22 is provided with stoppers 51 and 52 on both sides so as to be rotatable within an angle α range (90 ° + α °) slightly exceeding the front horizontal direction and the lower vertical direction. Therefore, the parking arm 22 rotates within a range of 90 ° + α ° with respect to the front horizontal direction. When the parking arm 22 exceeds the lower vertical direction, the fixed position is maintained by the action of the stopper 52 and the parking arm spring 43. That is, the motorcycle stand 100 performs vertical parking of the front wheel 2 at this position.

  4 shows a schematic configuration of the gear coupling mechanism 103 in a plan view, and FIG. 5 shows a detailed configuration of the gear coupling mechanism 103 in a side view. In these drawings, the gear coupling mechanism 103 includes a spring 61 provided on the fixed plate 21, a two-stage shaft 62 provided through the through hole of the fixed plate 21, a spring receiver 63 and an insulator 64, a wire receiver. 65, a wire attachment portion 66, and an insulator support portion 67. The central portion of the insulator 64 is received by the insulator support portion 67 so that the insulator 64 can be rotated. When the wire 25 is tensioned, the lever 64 rotates like a two-point sharp line, the lever 64 presses the spring receiver 63, and moves the intermediate gear 33 to the position of the two-point sharp line against the pressing force of the spring 61. Let In this position, the intermediate gear 33 meshes with the gears 31 and 32. Thereby, the rotational force of the gear 31 is transmitted to the gear 32 via the intermediate gear 33, and the rotational directions of the gear 31 and the gear 32 are the same.

  When the wire 25 is loosened, the insulator 64 returns to the position indicated by the solid line by the action of the spring 61, and the connection between the gear 31 and the gear 32 is cut off.

  FIG. 6 shows the configuration of the operation lever 23. The operation lever 23 includes an operation handle 71, a case 72, a wire take-up drum 73, and a drum center shaft 74. By operating the operation handle 71, the tightness of the wire 25 is controlled.

  As described above, the two-wheeled vehicle stand 100 provided on the front wheel 2 of FIG. 1 is attached to the left and right of the front wheel 2 respectively, and simultaneously with the levers 23 for operating the left and right two-wheeled vehicle stands installed on the handle 6 or the handle column 7. It has a structure to expand. The two-wheeled vehicle stand 100 is attached to the left and right sides of the axle 11 of the front wheel 2 and deploys the parking arm 22 around the parking arm rotating shaft 38 provided at a substantially intermediate position between the road surface 102 and the axle 11. 2 is suspended from the road surface 102 and parked. The bicycle parking arm rotation shaft 38 is provided at a position approximately in the middle of the road surface 102 and the axle 11 so that the tip of the bicycle parking arm 22 is positioned inside the front wheel 2 during traveling so that the bicycle parking arm 22 can walk. This is to avoid contact with the person.

  The parking arm 22 is provided with a gear mechanism that takes out the force of the rider to advance the two-wheeled vehicle as the rotational force of the front wheel 2, and the parking arm 22 is developed by this mechanism. In this way, the two-wheeled vehicle 101 that can be easily parked can be provided.

  The gear device constituting the rotational force transmission device shown in FIG. 2 that takes out the force by which the passenger advances the two-wheeled vehicle 101 as the rotational force of the front wheel 2 and deploys the parking arm 22 is a gear 31 that rotates integrally with the front wheel 2. , A gear 32 for deploying the parking arm 22, an intermediate gear 33 for transmitting and releasing the rotation of the gear 31 to the gear 32, making the rotation direction of the gear 31 and the gear 32 the same direction, A spring 61, a lever 64, a wire 25 for overcoming the force of the spring, and a handle for operating the wire 25, constituting the gear coupling mechanism 103 for engaging and releasing the gear 33 with the gear 31. 6 or an operating lever 23 provided on the handle column 7, a parking arm rotating shaft 38 integrated with a gear 32 for fixing one end of the parking arm 22 with a pin, a parking arm Constraining plate 39 to restrain the freedom of 2 to the vehicle body side towards, and a fixing plate 21 for fixing via the front fork 8 for fixing these components located in the front axle 11.

  The rotation speed of the front wheel 2 and the deployment speed of the parking arm 22 can be freely changed by changing the number of teeth or the diameter of the gear 31 and the gear 32.

  The operation method is such that by pulling or pushing the operation lever 23 provided on the handle 6, the gear 32 is engaged with the gear 31 by the wire 25 and the lever 64 and the two-wheeled vehicle 101 is slowly advanced. Then, the shaft 38 integrated with the gear 32 is rotated, and the parking arm 22 is rotated and moved slightly rearward from the lower portion of the axle 11 of the front wheel 2 from the storage position. The bicycle parking arm 22 is developed laterally by the restraining plate 39 along with the rotational movement. From this, the motorcycle stand 100 lifts the front wheel 2 by the parking arm 22 by the force to move the motorcycle forward and the inertial force, and two points of the parking arm 22 arranged on both sides of the front wheel part and one point of the rear wheel 3. A method of taking a stable parking posture is formed. The rotation range of the parking arm 22 is restricted by arranging the stoppers 51 and 52 at positions where the parking arm 22 is stable against gravity. The parking position of the parking arm 22 is maintained by providing the stopping means as described above at the position where the force of the parking arm spring 43 instructed at both ends of the parking arm 22 and the spring receiver 41 is sufficiently applied. by.

  The parking arm 22 is housed by rotating the operation lever 23 provided on the handle 6 in the opposite direction to the deployed state of the parking arm 22 and moving the intermediate gear 33 engaged with the gear 31 by the force of the spring 61 from the gear 31. Pull apart. At this time, the parking arm 22 is parked stably by gravity and the force of the parking arm spring 43 disposed on the parking arm 22. To release the motorcycle stand 100 (storage of the bicycle parking arm 22), the motorcycle 101 is pulled rearward from this state to shift the bicycle parking arm 22 to a position ahead of the axle 11 of the front wheel 2, and the parking arm spring 43 is released. This is done by returning to the storage position with force.

  For this reason, the two-wheeled vehicle stand 100 can be operated by safely operating the two-wheeled vehicle stand 100 without getting out of the two-wheeled vehicle.

  Although the gear 32 and the intermediate gear 33 slide and move in the axial direction, the gear 32 and the intermediate gear 33 are always kept in mesh with each other, and the meshing between the gear 31 and the intermediate gear 33 improves the ease of meshing. Further, the intermediate gear 33 can be realized by a method of always meshing with the gear 31 or the gear 32 and rotating the shaft of the intermediate gear 33 around the shaft of the gear 31 or the intermediate gear 33.

  Contrary to the aforementioned operation of deploying the parking arm 22 by moving forward, the motorcycle stand 100 attached to the left and right of the front wheel shaft can be mounted in the opposite direction in order to deploy the parking arm 22 by moving the motorcycle 101 backward. It becomes possible.

  Further, as described above, the motorcycle stand 100 can be used in the same manner even when attached to the rear wheel 3. A practical bicycle with a loading platform on the rear wheel 3 is an effective two-wheeler stand that is easier to use than before.

A spring 88 for meshing with the plate-shaped plate 80, a wire 25 for overcoming the force of the spring 88 and eliminating the meshing, an operating lever 23 (operating means) provided on the handle 6 or the handle column 7 for operating the wire 25 One end for moving the parking arm 22 is connected to the drive lever 84, and the other end is a lock that rotates around the rotating shaft 30 integrated with the axle 11 of the front wheel 2. It is connected to the part receiving 81, and a fixing plate 21 for mounting wire 84 transmits the rotation movement of the locking portion receiving 81 to bicycle arm 22, and their two-wheeled vehicle.

  The operating method is to rotate the operating lever 23 provided on the handle 6 to use the spring 88 for meshing the lock portion 83 with the lock portion 82 of the disk plate 80 and to engage the lock portion 83 with the lock portion 82. In addition, by slowly moving the two-wheeled vehicle 101 forward, the lock portion 83 is rotated about the rotation shaft 30, and the rotation of the front wheel 2 is transmitted to the drive lever 84 connected by the lock portion 82 and the wire 84. By unfolding the arm 22 and pushing it a little further, the front wheel 2 is lifted from the road surface 102 and parked at two points of the parking arm 22 on both sides of the front wheel 2 and one point of the rear wheel 3. At this time, the bicycle parking arm 22 has a structure that protrudes symmetrically to a position sufficient to prevent the motorcycle 101 from falling. For this reason, the rotating shaft 38 of the bicycle parking arm 22 is slightly upward with respect to the side of the motorcycle. The rotation range of the motorcycle stand 100 is constrained by disposing a stopper at a position where the parking arm 22 is stable against gravity. The parking position of the parking arm 22 is maintained by providing a stopper at a position where the force of the parking arm spring 43 is sufficiently applied.

  The parking arm 22 is stored by overturning the force of the spring 84 for engaging the lock portion 83 with the lock portion 83 by rotating the operating lever 23 provided on the handle 6 in the opposite direction to when the parking arm 22 is deployed. The engagement between the lock part 83 and the lock part 82 is released. At this time, the parking arm 22 is parked stably by gravity and the force of the parking arm spring 43 installed on the parking arm 22. Release of the stand (accommodation of the parking arm) is performed by pulling the two-wheeled vehicle 101 backward from this state and shifting the parking arm 22 to a position ahead of the front wheel 2 axle by the force of the parking arm spring 43. Returned to the storage position.

  For this reason, it becomes an easy-to-use motorcycle stand that operates the stand without getting off the motorcycle and parks safely.

  Contrary to the above-described operation of moving forward and deploying the parking arm, in order to move the two-wheeled vehicle backward and deploy the parking arm, the stands attached to the left and right of the front wheel shaft can be attached in reverse.

  Further, the front wheel stand can be used in the same manner even when attached to the rear wheel portion. For practical bicycles with a loading platform on the rear wheels, it is an effective stand that is easier to use than before.

  In the first and second embodiments, a first member that rotates together with the rotating shaft 30 that rotates integrally with the axle 11 of the front wheel 2 or the rear wheel 3, for example, the gear 31, and the rotational force of the first member are applied. The second member that rotates and transmits the rotational force associated with the rotation as the rotational force of the parking arm 22, for example, the gear 32, and the wire 25 is loosely connected to and away from the first member and the second member. Thus, a rotational force transmission device composed of an intermediate member that performs the above-described operation, for example, the intermediate gear 33 is configured.

  According to these embodiments, the two-wheeled vehicle stand 100 is provided on both sides of the front wheel 2 and the two-wheeled vehicle stand 100 provided on the front wheel 2 is parked at one point of the rear wheel and the two-wheeled vehicle at the time of parking. 101 is restrained from tilting and moving, so that the instability at the time of parking can be solved.

  A method for raising the motorcycle stand 100 will be described.

  In consideration of ease of use, the first method is a two-wheeled vehicle that has a width necessary to prevent the two-wheeled vehicle from falling and rotates around the axle 11 of the front wheel 2 and is stored behind the front wheel 2. This is a method in which the stand 100 for motorcycles is stood up by pushing the stand 100 on the motorcycle 101 with the feet of the passenger while riding the motorcycle 101 and backing the motorcycle 100 with the force of the passenger.

  The second method is a method in which the left and right independent two-wheeled vehicle stand 100 housed in the front part or the rear part of the front wheel is set up at the same time using the rotation of the front wheel 2 when pushing and pulling the two-wheeled vehicle 101. In this case, the front end of the parking arm 22 can be retracted to the side of the front wheel 2 and can be stored inside the peripheral end, which is the outer diameter of the front wheel, to prevent buffering with obstacles while the motorcycle is running. Thus, it is possible to provide the same ease of travel as the currently used motorcycle 100. A specific structure of the motorcycle stand 100 is a mechanism in which the motorcycle stand 100 on both sides protrudes from the two-wheeled vehicle 101 main body to the left and right outside when parking, and further reaches the bottom of the front wheel 2 so that the front wheel 2 floats. During use of the two-wheeled vehicle, the tip of the parking arm 22 housed by this mechanism is positioned closer to the axle 11 of the front wheel 2 than the front wheel rim. Further, the overhang to the left and right of the front wheel 2 is eliminated and the tip of the parking arm 22 is brought close to the front wheel width. In this way, the shape is set so as not to obstruct traveling.

  In order to perform the operation of deploying the parking arm 22 by the operation of moving the motorcycle 101 forward or backward, a mechanism for replacing the rotation angle of the front wheel 2 with the angle of the parking arm 22 is used.

  This mechanism can be realized by a mechanism in which various gears, belts and ratchets are arranged inside and outside the front wheel axle, and the rotation of the front wheel or the axle is transmitted to the axis of the parking arm or the parking arm in addition to the above-described embodiment. . Furthermore, a rod can be inserted between the parking arm 22 and the spoke 26 of the front wheel 2, and the rotation of the front wheel 2 can be directly transmitted to the parking arm 22 via the spoke 26 and deployed.

  Note that the influence of the stand weight on the steering wheel operation by attaching the motorcycle stand 100 to the front wheel 2 can be reduced by using a lightweight material such as magnesium alloy or aluminum alloy.
