Description

  The present invention relates to a bicycle stand device, and more particularly to a stand device that stably supports a bicycle while maintaining its position when temporarily stopped while riding, and can be easily stored at the start of movement. is there.

  Conventionally, a stand device is always provided in a bicycle. Such a stand device is generally intended to be stopped for a long time, and is provided for such a purpose, but it is natural that the bicycle is a two-wheeled vehicle. It is necessary as a function, but when traveling on the road, for example, at an intersection or a sidewalk, it is necessary to temporarily remove the foot on the pedal to get to the ground. For this reason, the bicycle itself must be tilted or the body (waist) must be removed from the saddle, which impairs smooth running.

  In addition, when cycling for a long time, for example, when driving on a general road, there are many places where the vehicle is temporarily stopped, which must be stopped as described above, which is also a cause of fatigue. It was.

  In the case of a sports bicycle, the above-described stand device is often not attached, and therefore a device as shown in JP 2001-105283 A has been proposed. However, in such a known example, since a grounding mechanism for stopping is provided in the pedal portion, there is a risk.

JP 2001-105283 A

  In other words, in actual use, if the leg 5 that sticks by the magnetic force is pushed downward by pushing the protruding part 10 protruding from the upper surface of the pedal with the foot, the leg 5 is grounded to the ground by the spring 7 and the position is maintained. However, there is a risk that the legs 5 may collide with the ground during driving, or the legs 5 may collide with the ground, or the pedals 10 may be pushed by the feet that are accidentally stepped on while driving. That is, there is a high risk and a large practical problem such as collision with the ground. It is an object of the present invention to provide a highly safe stand device that eliminates such danger.

  The stand device of the present invention comprises a pedal, a stand main body frame fixed to the fixed frame side of the bicycle so as to be located outside the rotation space, and a grounding means attached to the stand main body frame so as to be vertically movable. The grounding means is always elastically pressed upward with respect to the stand main body frame, and a pressing portion is provided on the upper end side of the grounding means.

  Since the stand device of the present invention is configured as described above, when it is stopped by a signal or the like during traveling, it can be safely stopped in the same posture, and can be easily returned to its original state when moving again. At the same time, since it is provided away from the pedal portion, there is an advantage that the traveling stop and the traveling start can be reliably and reliably performed without being affected by the depression of the pedal as in the prior art.

  The present invention will be described based on the illustrated embodiment. The apparatus of this embodiment is an example that is adopted in a bicycle stand apparatus.

  As shown in FIGS. 1 and 2, the stand device according to this embodiment includes a pedal between a fixed frame 10 of a bicycle body and a rotating shaft portion 11 of a rear wheel to which an end of the frame 10 is fixed. A stand body frame 20 having a substantially "<" shape formed so as to be outside the 12 movement (rotation) spaces, and a base 21 of the stand body frame 20, and perpendicular to the stand body frame 20 And grounding means 30 mounted so as to be movable in the direction.

  One end of the stand main body frame 20 is fixed to the fixed frame 10 close to the rotating shaft portion of the pedal 12. In this embodiment, the end portion is engaged with the fixed frame 10 and fixed by the engaging means 22 such as a bolt. On the other hand, the other end is integrally fixed to the outside of the rotating shaft 11 of the rear wheel by the same engaging means 23 as described above. A cylindrical shaft portion 24 is integrally fixed, and a through hole 25 is formed vertically in the center. The grounding means 30 is attached to the through hole 25.

  The grounding means 30 has a sliding shaft 31 that is slidable in the through hole 25 in the vertical direction, and a grounding protrusion 32 is fixed to the lower end and a pressing portion 33 is fixed to the upper end so as to be removable. A compression coil spring 34 is stretched between the pressing portion of the sliding shaft 31 and the upper end of the cylindrical shaft portion 24.

  Next, the operation of the bicycle stand device according to the embodiment configured as described above will be described. Normally, during a ride, for example, when stopping temporarily at an intersection or the like, the left foot is removed from the pedal 12 and placed on the pressing portion 33 of the grounding means 30 and pushed down immediately before the vehicle is stopped at a reduced speed. Then, the sliding shaft 31 descends against the compression coil spring 34, and the lower surface of the ground protrusion 32 is pressed against the ground. In this way, the bicycle can be stopped while keeping the posture at the time of riding by a simple operation of pushing down the sliding shaft 31 at the time of stopping. When leaving the vehicle, if the left foot is moved toward the pedal 12, the sliding shaft 31 is raised by the spring force and returns to the position shown in the figure, so that the operation can be continued as it is.

  Further, the grounding protrusion 32 at the lower end of the sliding shaft 31 may be made of metal or an elastic body such as a synthetic resin or hard rubber. Further, a rotating body such as a wheel (rubber, synthetic resin, etc.) can be mounted instead of the protrusion, and various design changes can be made.

  Although the above-described embodiment apparatus is installed on the left side of the bicycle body, it can be mounted on the right side as well, and only the shape of the stand body frame can be achieved by changing the orientation. Moreover, although demonstrated as a bicycle stand apparatus, it can use also for two-wheeled vehicles, such as not only that but a motorcycle.
