Description

  The present invention relates to a motorcycle (scooter) and a bicycle center stand device, and is intended to make it possible to perform a standing operation lightly and stably at the time of parking.

As a center stand device for motorcycles (scooters), the length of the support member (3) is shortened without the need for additional space around the cross pipe (2) of the body frame (1). As described in Japanese Patent Application Laid-Open No. 11-165668, there is an invention that makes it easy to stand up when parking a bicycle by bringing the fulcrum C of 6) close to the cross pipe (2) near the center of gravity G of the vehicle body. The support member (3) is fixed to the cross pipe (2) of the frame (1), and the main leg (6) is pivotally supported around the fulcrum of the support member (3) between the standing position and the storage position. The hook (9) is pivotably locked to the outer periphery of the cross pipe (2), and a tension spring (8) is placed between the hook (9) and the spring support member (7) of the main leg (6). It is stretched. (Figure 2)
Therefore, as described later, this invention is different from the present invention.

  Bicycle (including electric bicycle) stand devices (center stands) have their lower ends of the stand member grounded by a foot kicking up operation of the stand upright member and an operation of pulling the vehicle body obliquely backward. This is because the weight of the car body itself is relatively light, but if a woman puts a child or a heavy baggage recently, there is a risk that it will be difficult to ground the lower end of the stand member when standing up and the car body will fall down.

  There is no stand device (center stand) for bicycles (including electric bicycles) that may conflict with the present invention.

JP, 11-165668, A The invention concerning the center stand device of a motorcycle of JP 11-165668 is a fulcrum of the upper end of the main leg (6) by shortening the length of the support member (3). (C) is fixed to the cross pipe (2) near the center of gravity (G) of the vehicle body, and the standing operation when parking is easily performed.

  However, as described in the summary solution, the present invention fixes the supporting member (3) having a short length to the cross pipe (2) of the vehicle body frame (1), and supports the supporting point (C) of the supporting member (3). The main leg (6) is rotatably supported around the standing position and the storage position.

  The invention according to claim 1 is applied to a scooter, and branches in a reverse Y shape from the center of a leg rod connected to the lower part of the body frame in a tiltable manner in the running direction, and its front lower end The first grounding part that contacts the ground first when turning from the center stand flipping position during traveling to the standing position during parking, and the rear side bending from the vehicle body to the side and extending in an L shape to stand the vehicle body A second grounding portion for maintaining the state is provided, and the vehicle body is lifted by stepping on the L-shaped end portion of the second grounding portion.

  The invention according to claim 2 is applied to a bicycle, and a pair of left and right extending downward from a known member rotatably attached to each lower end portion of a body frame that is connected to a saddle pipe in a triangular shape. A foot pedal is projected in the middle of the heel of the heel, projecting in a generally toroidal shape toward the rear of the vehicle body, and a U-shaped heel member is combined in a heart shape at the lower end of the heel so that the center stand can be lifted When turning from the position to the standing position at the time of parking, an arcuate end surface that contacts the ground first is formed in the two first grounding portions and the second grounding portion, and downward from the first grounding portion and the second grounding portion. The lower end of the extending leg is substantially expanded to the outside of the vehicle body and is bent obliquely upward, and is separated and expanded below the rear wheel of the bicycle to form a mountain shape, and the left and right leg are connected. Other bicycle center stand devices I can't find it.

  The invention of claim 1 when implemented in the scooter A is configured as follows.

  A leg rod 2 that is pivotably connected to the lower part of the body frame 1 is branched in an inverted Y shape from the center to the running direction, and its front lower end 2a is bent slightly toward the rear of the car body. When turning from the center stand lifting position (Fig. 4) to the standing position during parking (Fig. 5), the first grounding portion 3 is the first to be grounded, A second grounding portion 4a that is bent laterally from the vehicle body frame 1 and extends in an L shape to hold the vehicle body in an upright state, and 4b that is shorter than 4a are provided. When the L-shaped end of one second grounding part 4a is stepped on, it is stored in the direction that follows the body frame 1 at the position where the leg 2 is flipped up, and the leg 2 is within the range narrower than the handlebar width, making it easy to ride. In addition, the attention to the side of the vehicle body during traveling is reduced. When the L-shaped end of the second grounding portion 4a is continuously depressed, the leg rod 2 rotates and reaches the standing position (FIG. 5) during parking, so that the vehicle body is reliably erected.

  The upper mounting plate 5a of the center stand 5 is attached by inserting the piped pipe 6 into the lower part of the body frame 1, and the tension spring 7 is attached to the lower part of the body frame 1 and the second grounding part 4b.

The invention according to claim 2 when implemented on the bicycle B including the electric bicycle is configured as follows.
