  However, the motorcycle described in Patent Document 1 described above requires both a parking stand that is used during normal times and a footrest that is used as a parking stand during maintenance. Moreover, in the two-wheeled vehicle described in Patent Document 2, the size of the two-wheeled vehicle increases, the number of parts increases, and the cost also increases.

  The present invention has been made to address the above-described problems, and an object of the present invention is to provide a motorcycle / tricycle standing apparatus capable of using a footrest as a parking stand by adjusting the vehicle height. is there.

  In order to achieve the above-mentioned object, the structural features of the motorcycle / tricycle standing device according to the present invention are characterized in that a front wheel and a rear wheel are provided on the front and rear sides of the vehicle body, respectively, This is an upright device for motorcycles and tricycles equipped with a footrest with a vehicle height adjustment mechanism that adjusts the height of the vehicle body relative to the road surface, and when the vehicle body is lowered by the operation of the vehicle height adjustment mechanism, the footrest is placed on the road surface. It is that the vehicle body can be held in an upright state by grounding.

  In the motorcycle / tricycle upright apparatus according to the present invention, the footrest provided in the motorcycle / tricycle is conventionally grounded on the road surface instead of the parking stand by using the vehicle height adjusting mechanism. There is no need to provide it. As a result, motorcycles and tricycles are reduced in size, and the number of parts is reduced, resulting in low cost. Further, when the footrest comes in contact with the ground, the vehicle height is lowered, so that the driver can easily get on. That is, the motorcycle or tricycle according to the present invention is set in a state suitable for traveling by increasing the vehicle height by driving the vehicle height adjustment mechanism after the driver gets on the vehicle with the vehicle height lowered. Can do. Note that the motor tricycle according to the present invention can travel while swinging left and right during a turn or the like, and when stationary, without a standing device, it is difficult to achieve a stable standing state.

  In addition, another structural feature of the motorcycle / tricycle standing apparatus according to the present invention is that the vehicle height adjusting mechanism includes at least one of a front wheel suspension device that supports a front wheel and a rear wheel suspension device that supports a rear wheel. It is in that. According to this, since each suspension device originally has a mechanism for changing the vehicle height for absorbing shock, the vehicle height adjustment mechanism is made simple by providing the vehicle height adjustment mechanism in this part. be able to. When the vehicle height adjustment mechanism is provided on the front wheel suspension device, the front side of the vehicle body is lowered so that the footrest comes into contact with the ground, and when the vehicle height adjustment mechanism is provided on the rear wheel suspension device, the vehicle rear portion side is low. The footrest comes to ground. Further, when the vehicle height adjusting mechanism is provided in both the front wheel suspension device and the rear wheel suspension device, the entire vehicle body is lowered and the footrest comes to ground.

According to the present invention, the motorcycle or three-wheeled vehicle includes at least two adjustment mechanisms among the suspension device side vehicle height adjustment mechanism, the connecting portion distance adjustment mechanism, and the footrest adjustment mechanism, and the at least two adjustment mechanisms are simultaneously used. Since it can be operated, the height adjustment amount of the footrest by each adjustment mechanism can be added. For this reason, each adjustment mechanism can be reduced in size.

  In addition, another structural feature of the upright apparatus for motorcycles and tricycles according to the present invention is that the connecting member is composed of an expansion / contraction shaft-like member composed of two shaft-like members assembled in a telescopic manner. The shaft-shaped member is installed so that the body-body-side coupling portion is lower than the head-pipe-side coupling portion, so that the telescopic shaft-shaped member cannot swing relative to the head pipe and the vehicle body. It is in.

  According to this, it is possible to adjust the distance between the front wheel and the rear wheel while keeping the caster angle of the front wheel substantially constant. Further, the head pipe and the vehicle body main body are firmly connected by the connecting member, and the rigidity of the vehicle body is improved. Further, the connecting member can be constituted by a pair of telescopic shaft-like members provided in parallel in the vertical direction, and according to this, the rigidity of the vehicle body can be further improved.

It comprises a fitting member with a shaft, each one end of the pair of telescopic shaft-like members is connected to the head pipe, and each other end is connected to the vehicle body body, That is, the fitting members connected to the vehicle body are connected by a horizontal member. According to this, since the expansion / contraction adjustment of the pair of expansion / contraction shaft-shaped members constituting the connection member and the expansion / contraction adjustment of the hydraulic shock absorber are performed independently, the connection member can be adjusted without adjusting the expansion / contraction of the hydraulic shock absorber. Can be expanded and contracted.

  In addition, still another structural feature of the upright apparatus for motorcycles and tricycles according to the present invention is that the pair of telescopic shaft members are fitted into the fitting cylinder and the fitting cylinder so as to be slidably fitted. It comprises a fitting member with a shaft, each one end of the pair of telescopic shaft-like members is connected to the head pipe, and each other end is connected to the vehicle body body, That is, the fitting members connected to the head pipe are connected by a horizontal member. According to this, since it is possible to adjust the expansion and contraction of the hydraulic shock absorber so as to adjust the vehicle height in the same direction as the expansion and contraction of the connection member only by adjusting the expansion and contraction of the connection member, The distance between can be adjusted greatly.

  Still another structural feature of the upright apparatus for motorcycles and tricycles according to the present invention is that a control device for controlling the operation of the vehicle height adjustment mechanism to ground the footrest to the road surface, and the motorcycle and tricycle are in a running state. And a running state detecting means for detecting whether or not the vehicle is in a running state when the running state detecting means detects that the motorcycle is in a running state, the control device prevents the footrest from contacting the road surface.

Furthermore, an operation element for operating each driving device such as the actuator 26 and the motor 38a is also provided. If the controller 57 determines that the motorcycle 10 is traveling by detecting the speed of the speed sensor, the controller 57 stops a predetermined operation among the operations of the actuators 26, 34a, 34b, the motor 38a, and the motor 47. Thus, control is also performed to prevent the grounding members 44a and 44b of the footrest from contacting the road surface R. Note that the vehicle body 10a including the vehicle height adjusting mechanism 20, the inter-connector distance adjusting mechanism, the telescopic mechanism 38, and the footrest adjusting mechanism 40 constitutes the standing device of the present invention.

  In this configuration, when the driver D rides on the motorcycle 10, the driver D has the grounding member 44a, 44b of the footrest touches the road surface R as shown in FIG. Sit on the seat 15 and turn on the main switch. Next, the driver D puts both feet on the footrest portions 40a and 40b, respectively, and operates a predetermined operation element, for example, to obtain the state shown in FIG. FIG. 6 shows a state in which the vehicle height adjusting mechanism 20 and the telescopic mechanism 38 are extended from the motorcycle 10 shown in FIG. 1 and the rotation connecting portion 13c is operated to make the seat coupling members 51a and 51b substantially vertical. . Thereby, the height from the road surface R of the entire vehicle body 10a is increased.

That is, when the telescopic shaft portions 24 and 25 of the vehicle height adjusting mechanism 20 extend, the height of the front side portion of the vehicle body 10a from the road surface R increases. Further, when the expansion / contraction mechanism 38 extends, the lower end portion of the rotation support member 36 is pushed rearward, and the rotation support member 36 rotates rearward about the support shaft 36a and becomes nearly vertical. For this reason, the rear arm 14 is rotated by the rotation support member 36 via the connecting piece 39, and accordingly, the vehicle body 13 is also raised via the brackets 41a and 41b to which the rear arm 14 is connected. The height of the rear side portion from the road surface R also increases.

Furthermore, since the height of the seat 15 with respect to the vehicle body 13 is increased by the operation of the rotation driving unit 13c, the motorcycle 10 has a shape suitable for traveling. In this case, the driver D straddles the motorcycle 10 with the lower vehicle body 10a, and after the driver D straddles the motorcycle 10, the vehicle body 10a becomes higher, so that the driver D rides a camel. It is possible to get on the motorcycle 10 with a sense and it will be interesting.

  When the driver D operates the grip 29b, the motorcycle 10 accelerates according to the operation of the grip 29b. In this case, the front switch 11a and the rear wheel 11b are both driven by operating the changeover switch or automatically controlled, or only one of the front wheels 11a and the rear wheels 11b is driven. The driving torque can be changed and driven. Further, when the traveling speed of the motorcycle 10 is lowered, the brake levers 23a and 23b are operated to suppress the rotational driving of the front wheels 11a and the rear wheels 11b. When an impact is applied to the motorcycle 10 due to unevenness of the road surface R or the like during traveling, the impact is mitigated by the front fork 16 and the hydraulic shock absorber 37.

  And when driving the motorcycle 10 in a state where the distance between the body of the driver D and the handles 22a, 22b is widened and the driver D has a lower center of gravity, as shown in FIG. At the same time, the rotation drive unit 13c is operated so that the sheet connecting members 51a and 51b are inclined obliquely rearward. That is, when the telescopic shaft members 31 and 32 of the connecting member 30 are extended, the length of the vehicle body 10a in the front-rear direction is increased. In addition, since the height of the seat 15 with respect to the vehicle body 13 is lowered and the seat 15 moves rearward due to the operation of the rotation drive unit 13c, the driver D places the body at a lower position on the rear side of the vehicle body 10a. Thus, the handles 22a and 22b located at a high position in the front are operated.

  Further, when the driver D is driving with his / her legs bent and the body is rolled up, as shown in FIG. 8, the arm drive unit 46 is driven to rotate so that the arm members 43a and 43b face obliquely rearward. To tilt. That is, when the motor 47 of the arm drive unit 46 is operated, the rotating bodies 46a and 46b are rotated, and the elongated holes 45a and 45b are engaged with the engaging protrusions 48a and 48b, so that the arm members 43a and 43b are engaged. Also move like a pendulum according to the rotation of the rotating bodies 46a and 46b.

Therefore, as shown in FIG. 8, when the arm members 43a and 43b are inclined obliquely backward, the motor 47 is stopped at an arbitrary inclination angle position so that the reduction mechanisms 49a and 49b have a large reduction ratio. Therefore, the arm members 43a and 43b can be held in that state. In this state, since the footrest portions 40a and 40b are located directly below the body of the driver D, the driver D can drive the vehicle with the legs bent and the body rounded.

  Further, when the driver D is driving with his body stretched and his upper body tilted backward, as shown in FIG. 9, the arm drive unit 46 is driven to rotate so that the arm members 43a and 43b are inclined forward. In addition to inclining, the motor of the rotational drive unit 52c is operated so that the seat rear portion 15b is inclined obliquely upward rearward. In this state, the footrest portions 40a and 40b are located at positions away from the front lower part of the body of the driver D, and the seat rear portion 15b extends rearward and obliquely upward. It is possible to drive in a state where the body is inclined obliquely upward with the backrest as the backrest.

  Further, when the driver D does not sit on the seat 15 and performs an acrobatic operation while standing, as shown in FIG. 10, the motor of the rotational drive unit 52c is operated to further open the seat rear portion 15b. Rotate it so that it leans forward and diagonally upward. And the driver | operator D can drive | operate in the state which stood on the buffer member 55a etc. which were provided in the rear-wheel 11b, and supported the body in the seat rear part 15b and the battery accommodating parts 53a and 53b.

If the height of the vehicle body 10a is reduced while the motorcycle 10 is traveling and the distance between the footrest grounding members 44a and 44b and the road surface R becomes a predetermined value set in advance, the controller 57 By the control, a predetermined operation among the operations of the actuators 26, 34a, 34b, the motor 38a, and the motor 47 is stopped, and the grounding members 44a, 44b of the footrest are prevented from contacting the road surface R. In this case, the height of the ground members 44a and 44b from the road surface R is calculated from the driving state of each driving device such as the actuator 26.

When the traveling of the motorcycle 10 is terminated, the motorcycle 10 is stopped by operating the brake levers 23a and 23b. Next, by operating a predetermined operation element, the vehicle body 10a is lowered, the grounding members 44a and 44b of the footrest are grounded on the road surface R, and the motorcycle 10 is stationary in a standing state. Then, the main switch is turned off. At this time, if the charge amount of the battery is reduced, a connection cord (not shown) for charging is connected to the battery to charge the battery.

  As described above, in the motorcycle 10 according to the present invention, the vehicle height is adjusted using the vehicle height adjusting mechanism 20, the distance adjusting mechanism between the connecting portions including the connecting member 30, and the telescopic mechanism 38, or the footrest adjusting mechanism 40. And the grounding members 44a and 44b of the footrest are grounded to keep the motorcycle 10 standing up. Therefore, it is not necessary to separately provide a parking stand, and the motorcycle 10 can be downsized and the number of parts can be reduced, resulting in low cost. Further, when the footrest grounding members 44a and 44b are grounded, the vehicle height is lowered, so that the driver D can easily get on the motorcycle 10.

  Further, the inter-connector distance adjusting mechanism can be used not only as a vehicle height adjusting mechanism for adjusting the vehicle height, but also as a mechanism for adjusting the caster angle and the wheel base of the front wheel 11a. For this reason, by combining the distance adjusting mechanism between the connecting portions, the other vehicle height adjusting mechanism 20, the telescopic mechanism 38 and the footrest adjusting mechanism 40, the length in the front-rear direction of the motorcycle 10, the front wheel 11a side and the rear wheel 11b side. Can be arbitrarily changed, and the shape of the motorcycle 10 can be freely changed. Furthermore, since the connecting member 30 is composed of the pair of telescopic shaft-shaped members 31, 32, the rigidity of the vehicle body 10a can be improved.

  In addition, since the link mechanism is configured by the telescopic shaft-like members 31 and 32, the head pipe 12 and the vehicle body 13 constituting the connecting member 30, the length of the telescopic shaft-like member 31 and the length of the telescopic shaft-like member 32 are set. The caster angle and the wheel base of the front wheel 11a can be greatly changed by using different lengths. As a result, the shape of the vehicle body 10a can be changed greatly. Furthermore, the rigidity of the vehicle body 10a is further improved by spanning and fixing the horizontal member 35 on the telescopic shaft members 31 and 32 constituting the connecting member 30.

Further, since one end portion of the hydraulic shock absorber 37 is supported by the horizontal member 35, it is not necessary to separately provide a member or a horizontal member for supporting the hydraulic shock absorber 37, and the standing device is reduced in size and the number of parts is reduced. Reduced and cheaper. Further, when the vehicle speed sensor detects that the motorcycle 10 is in a traveling state, the operation of a predetermined motor among the actuators 26, 34a, 34b and the motors 38a, 47 is stopped under the control of the controller 57, It is possible to prevent the ground members 44a and 44b from contacting the road surface R.

For this reason, it is possible to prevent the grounding members 44a and 44b from contacting the road surface R and preventing the traveling or the footrest adjusting mechanism 40 from being damaged during traveling. Further, as shown in FIG. 10, when the seat rear portion 15b is inclined so as to face obliquely upward in the front, the battery housing portions 53a, 53b also incline so as to face obliquely upward in the front together with the seat rear portion 15b. The driver D can use the battery housing portions 53a and 53b as a restricting member for restricting left and right shaking of the body.

Further, the motorcycle or tricycle according to the present invention is not limited to the above-described embodiment, and can be appropriately modified. For example, in the above-described embodiment, the suspension device side vehicle height adjustment mechanism is configured by both the vehicle height adjustment mechanism 20 and the expansion / contraction mechanism 38 provided in the rear wheel suspension device, but only one of them may be provided. Further, in the embodiment described above, the motorcycle 10 includes the suspension device side vehicle height adjustment mechanism, the inter-connector distance adjustment mechanism, and the footrest adjustment mechanism 40, but only two of these mechanisms are provided. A vehicle height adjusting mechanism can also be configured.

  In the above-described embodiment, the support shafts 33a and 33b and the rotation drive unit 13c are made rotatable so that the link member is formed by the connecting member 30, the vehicle body 13 and the head pipe 12. The connecting member 30 can be fixed to the pipe 12 so as not to move, and the frames 13a and 13b of the vehicle body 13 can be prevented from swinging with respect to each other. According to this, the rigidity of the vehicle body 10a is improved. Further, in the above-described embodiment, the horizontal member 35 is stretched over the fitting cylinders 31a and 32a, and one end portion of the hydraulic shock absorber 37 is connected to the horizontal member 35. It is also possible to hang over the fitting shafts 31b and 32b.

According to this, since the hydraulic shock absorber 37 can be expanded and contracted at the same time only by expanding and contracting the connecting member 30, the distance between the footrest and the road surface R can be largely adjusted accordingly. Moreover, the one end part of the hydraulic shock absorber 37 can be connected to the head pipe 12, and the distance between the footrest and the road surface R can be greatly adjusted. Further, in the above-described embodiment, the controller 57 controls the ground members 44a and 44b not to contact the road surface R based on the travel detection by the vehicle speed sensor. A sensor for detecting the state can be used.

In this case, the sensor detects whether or not the parking brake is in operation, and when the parking brake is not in operation, the controller 57 controls the ground members 44a and 44b not to contact the road surface R. In the above-described embodiment, the footrest is composed of the footrest portions 40a and 40b and the grounding members 44a and 44b. However, the footrest portions 40a and 40b may be grounded without providing the grounding members 44a and 44b. Furthermore, the grounding members 44a and 44b can be constituted by wheels so that they can be rotated while being grounded. Further, although the motorcycle / tricycle is the motorcycle 10, it goes without saying that the present invention includes the motorcycle.
