  However, the above-described conventional two-wheeled vehicle parking device includes a clamp portion that holds the two-wheeled vehicle in an upright state by sandwiching a front wheel of the two-wheeled vehicle, a stopper portion that fixes a rear portion of the front wheel, and a driving unit that operates each of them. Therefore, the number of parts increases, the structure becomes complicated, and the cost increases.

  The present invention has been made in order to cope with such a problem, and an object of the present invention is to provide a two-wheeled vehicle having a simple structure capable of holding the two-wheeled vehicle in a standing state while preventing the two-wheeled vehicle from coming out rearward. It is to provide a parking device. In the description of each constituent element of the present invention below, the reference numerals of corresponding portions of the embodiment are shown in parentheses in order to facilitate understanding of the present invention. The present invention should not be construed as being limited to the configurations of the corresponding portions indicated by the reference numerals of the forms.

  In order to achieve the above-described object, the structural feature of the motorcycle parking apparatus according to the present invention is that the motorcycle is held upright by holding the front wheel (FW) of the motorcycle (A) from both the left and right sides. It is a device (10, 40), and a support base (12) for supporting the lower part of the front wheel and a support base (12) are arranged so as to be relatively close to and away from each other, and the front wheel can be clamped by approaching each other And a pair of clamping parts (17, 18) that release the clamping of the front wheel by being separated from each other, and at least one of the pair of clamping parts, when the pair of clamping parts clamp the front wheel, the pair of clamping parts An inclined portion is formed so that the rear portion is shorter in the rear portion than in the front portion, thereby preventing the two-wheeled vehicle from moving backward.

  In the two-wheeled vehicle parking apparatus according to the present invention, a pair of holding portions that hold the two-wheeled vehicle in an upright state by holding the front wheel is provided with a mechanism that prevents the two-wheeled vehicle from moving backward. For this reason, it becomes unnecessary to provide a mechanism for preventing the two-wheeled vehicle from moving backward in addition to the pair of sandwiching portions. Further, the mechanism for preventing the two-wheeled vehicle from moving backward is provided with a pair of inclined portions so that when the pair of sandwiching portions sandwich the front wheel, the distance between the pair of sandwiching portions is shorter at the rear than at the front. Since it is configured by forming at least one of the sandwiching portions, the motorcycle can be prevented from moving backward with a very simple configuration.

  In this case, the pair of sandwiching portions may be moved toward and away from each other by moving both, or one may be fixed and may be moved toward and away from each other by moving the other. Moreover, it is preferable that the part clamped by a pair of clamping part in a front wheel is a lower part part. Further, the interval between the pair of sandwiching portions may be such that the rear portion is shorter than the front portion when the pair of sandwiching portions approach and sandwich the front wheel, and the pair of sandwiching portions are separated from each other. , It can be in any relationship.

  Another structural feature of the parking device for a motorcycle according to the present invention is that the inclined portion is in contact with at least the front inner peripheral portion of the front wheel or the outer peripheral portion of the lower rear portion. In this case, the front inner peripheral side portion of the front wheel is preferably a tire portion made of rubber, not a wheel portion made of metal. Moreover, the outer peripheral side part of the rear lower part of the front wheel is a lower outer peripheral part on the rear side of the front wheel in the front-rear direction. According to the present invention, the inclined portion can be formed not on one or both of the pair of sandwiching portions but on a part thereof. For example, most of the pair of sandwiching portions can be formed so as to be parallel to each other, and the inclined portion can be formed only in a portion facing the front inner peripheral portion of the front wheel or the rear lower peripheral portion. According to this, it is possible to prevent the two-wheeled vehicle from moving backward while pressing the left and right sides of the front wheel substantially equally.

  Still another structural feature of the parking device for a motorcycle according to the present invention is that the front and rear inclined surfaces are inclined upward and backward from the front (14) of the support base where the lower rear side of the front wheel is located. (15b) is provided to prevent the motorcycle from moving backward. According to the present invention, in addition to the inclined portions provided in the pair of sandwiching portions, the front and rear direction inclined surfaces also prevent the two-wheeled vehicle from moving backward, so that the two-wheeled vehicle can be more reliably prevented from moving backward.

  Still another structural feature of the parking device for a motorcycle according to the present invention is that the pair of sandwiching portions includes a fixed portion (17) and a movable portion (18) that can move forward and backward with respect to the fixed portion. At least the moving part side portion of the base is provided with a laterally inclined surface (16) inclined downward from the moving part side toward the fixed part side so that the front wheel is urged toward the fixed part side. It is in.

  According to the present invention, when the front wheel is placed on the support base, the front wheel is positioned on the fixed portion side by the inclined surface in the left-right direction. When moving the moving part in that state and holding the front wheel with the fixed part, the front wheel does not move in the left-right direction and is fixed as it is, so when holding the front wheel with a pair of holding parts The driving force can be reduced, and the front wheels can be fixed in a state where the two-wheeled vehicle is held in a stable posture.

  Still another structural feature of the parking device for a motorcycle according to the present invention is that the pair of sandwiching portions includes a fixed portion and a movable portion that can move forward and backward with respect to the fixed portion, and at least the movable portion side of the support base. In this part, a laterally inclined surface inclined downward from the moving part side toward the fixed part side is provided so that the front wheel is urged toward the fixed part side, and the rear part of the lower part of the front wheel in the support base In the part where the side is located, a front and rear inclined surface that is inclined upward from the front to the rear is provided to prevent the motorcycle from moving backward, and the left and right inclined surfaces are further rearward than the front and rear inclined surfaces. It is in having arranged in.

  In the present invention, the support base is provided with a left-right direction inclined surface that urges the front wheel toward the fixed portion and a front-rear direction inclined surface that prevents the two-wheeled vehicle from moving backward, and the left-right direction inclined surface is more than the front-rear direction inclined surface. Is also located behind. For this reason, when the two-wheeled vehicle is brought close to the two-wheeled vehicle parking device and the front wheel is placed on the support base, the front wheel advances while being urged toward the fixed portion by the left-right direction inclined surface, and further, the rear portion of the front wheel becomes the front-rear inclined surface. When positioned, it is prevented from moving backward. Therefore, when placing the front wheel on the support base, the front wheel will naturally advance to the fixed section side without consciously pushing the front wheel to the fixed section side. The operation of positioning to becomes easy.

In addition, the base box 29 is installed at the front center in the left-right direction on the upper surface of the floor surface portion 11.

  The control device provided in the base box 29 operates the motor 22 by operating the foot switch 28, and operates the motor 22 when the limit switches 27a and 27b come into contact with the detected piece 25c and are turned on. Stop. Further, the control device stops the operation of the motor 22 when a load of a predetermined value or more is generated in the moving unit 18 and the current value of the motor 22 reaches a predetermined value. In this case, the tire pressure is set to 150 kgf, for example. In addition, a limit switch 27c that can be moved forward and backward is provided at the center of the upper surface of the front support base 13, and when the front wheel FW of the motorcycle A is positioned on the front support base 13, it is pushed forward. Retreats to the inside of the part support 13 and turns on. Accordingly, it is detected that the front wheel FW is located on the front support base 13.

  The display device 30 is installed on the left side of the base box 29 on the upper surface of the floor surface portion 11, and is green on the upper front surface (surface facing rearward) of the vertically extending square bar-shaped support portion 31 from above to below. A lamp 32a, a yellow lamp 32b, and a red lamp 32c are installed at regular intervals. The green lamp 32a, the yellow lamp 32b, and the red lamp 32c are respectively controlled by the control device described above, and the green lamp 32a is lit when the limit switch 27a is on and the limit switches 27b and 27c are off. When both the limit switch 27a and the limit switch 27c are on (the limit switch 27b is off), the green lamp 32a blinks.

  Further, when the limit switches 27a and 27b are in the off state, the limit switch 27c is in the on state, and the current value of the motor 22 that has started operation reaches a predetermined value and the operation of the motor 22 stops, The lamp 32b is turned on. Further, a settlement apparatus (not shown) is installed in the vicinity of the motorcycle parking apparatus 10, and when the settlement is completed with this settlement apparatus in a state where the yellow lamp 32b is lit, the yellow lamp 32b changes from lighting to blinking. change. When the limit switch 27c is turned off from that state, the yellow lamp 32b is turned off and the green lamp 32a is turned on. The red lamp 32c is lit when a malfunction or failure occurs in the motorcycle parking apparatus 10 or when a large force in the backward direction is applied to the moving unit 18. In addition, an explanation display board 33 on which an operation explanation for entering and leaving the motorcycle A is attached to the upper right side of the support portion 31.

  Next, an operation when the motorcycle A is moved in and out of the motorcycle parking apparatus 10 thus configured will be described. In this case, first, as shown in FIG. 2, the motorcycle A is parked for two-wheelers from the right rear side of the two-wheeled vehicle parking device 10 in a state where the moving unit 18 moves backward and the green lamp 32a of the display device 30 is lit. The front wheel FW is positioned on the support 12 by moving to the device 10 side. At this time, the front wheel FW moves over the rear support base 14, but the inclined surface portion 16 provided on the rear side of the rear support base 14 is higher on the left side and lower on the right side. It moves while being urged from the fixed portion 17a side to the fixed portion 17 side.

  When the front wheel FW is positioned on both the upper surface of the front support base 13 and the inclined surface 15b of the base 15 across the ridge line portion 16a and the ridge line portion 15a of the rear support base 14, the lower right side surface of the front wheel FW Is in contact with the fixed portion 17 and the rear fixed portion 17a, and the front and rear portions of the lower portion of the front wheel FW are in contact with the inclined surface of the front support 13 and the inclined surface 15b of the base 15, respectively. Accordingly, the front wheel FW is held in a stable state in which it is difficult to move both front and rear and left and right. At this time, the limit switch 27c is turned on by pressing the front wheel FW, and the green lamp 32a blinks.

  In this state, the foot switch 28 is pressed by stepping on with a foot. As a result, the motor 22 starts operating, the rotation shaft rotates in one direction together with the dry cylinder 23, and the ball screw 23a, the slide shafts 25a and 25b, the mounting plate 26, the cover 26a and the moving part 18 move forward together. . Then, when the moving part 18 abuts on the left side of the front wheel FW and further presses the front wheel FW toward the fixing part 17, when the fixing of the front wheel FW is completed, the operation of the motor 22 is stopped and the front wheel FW is fixed. Maintained in a state.

  In this case, the rotating shaft is locked by the electromagnetic brake provided in the motor 22, and the stroke of the ball screw 23a is maintained. As a result, the motorcycle A is maintained in the standing state. Further, since the rear part of the moving part 18 protrudes to the right side from the front part, the front wheel FW is more strongly clamped on the lower rear part side, and the motorcycle A is reliably prevented from moving backward. In this case, the inner peripheral side of the front wheel FW is more strongly clamped than the outer peripheral side of the front wheel FW. At this time, the green lamp 32a is turned off and the yellow lamp 32b is turned on, and the state is maintained thereafter.

  Then, when the motorcycle A is issued, a fee corresponding to the usage time is paid to the settlement apparatus. As a result, the yellow lamp 32b blinks. In this state, the foot switch 28 is pressed by stepping on with a foot. As a result, the motor 22 starts operating, and the rotating shaft rotates together with the dry cylinder 23 in the other direction, that is, in the opposite direction to the one described above, and the ball screw 23a, slide shafts 25a and 25b, the mounting plate 26, the cover 26a and the moving part. 18 moves together. At that time, the motorcycle A is supported by hand so as not to fall down.

  Then, when the detected piece 25c presses the limit switch 27a and the limit switch 27a is turned on by the retraction of the slide shaft 25a, the operation of the motor 22 is stopped. In this state, the motorcycle A is moved backward from the motorcycle parking device 10. As a result, the limit switch 27c is turned off, the yellow lamp 32b is turned off, the green lamp 32a is turned on, and the two-wheeled vehicle parking apparatus 10 is ready to enter.

  When the width of the front wheel FW is 50 mm or less, when the moving part 18 moves forward by the operation of the motor 22, the detected piece 25c presses the limit switch 27b before coming into contact with the front wheel FW. 27b is turned on. Thereby, after the operation of the motor 22 is temporarily stopped, the motor 22 rotates in the reverse direction, and the slide shaft 25a, the moving unit 18 and the like are moved backward to a position where the detected piece 25c presses the limit switch 27a. That is, in the motorcycle parking apparatus 10, when the width of the front wheel FW is 50 mm or less, the moving unit 18 moves back to the initial position without moving forward until the distance from the fixed unit 17 is 50 mm or less. .

  As described above, in the motorcycle parking apparatus 10, the mechanism for preventing the parked motorcycle A from moving backward is the movement of the fixed unit 17 and the moving unit 18 that hold the motorcycle A in an upright state. The part 18 is configured with a very simple structure in which the part 18 is inclined with respect to the fixed part 17. For this reason, manufacture of the parking apparatus 10 for two-wheeled vehicles becomes easy, and price reduction is attained. Further, in the portion of the support base 12 where the front side of the lower part of the front wheel FW is located, a front support base 13 that is inclined upward and backward from the rear is provided, and at the part where the rear side of the lower part of the front wheel FW is located A base 15 having an inclined surface 15b that is inclined upward from the front to the rear is provided to prevent the motorcycle A from moving forward or backward. For this reason, in addition to the inclined surface of the moving part 18, the base 15 also prevents the motorcycle A from moving backward, and the motorcycle A can be more reliably prevented from moving backward.
