Description

  The present invention relates to a bicycle, and more particularly to a traffic bicycle that also serves as a local exercise bicycle.

  In recent years, bicycles have become indispensable for people living in urban areas for health promotion, dieting, commuting and shopping. Normally, this type of bicycle is almost equipped with a stand and a loading platform for the convenience of use.

  Also, if you are going to do a rowing exercise using this type of bicycle indoors or in the garden instead of going outside, for example for health promotion and dieting even in the rainy days The legs cannot be achieved by lifting the rear wheel from the ground with the leg stand, which is a thin foot that is often seen on bicycles at present, so buy a device dedicated to bicycle training and install it on the bicycle as described above. Must be used for

  The present invention has been made in view of the above circumstances, and firstly, it is a first object of the present invention to provide a bicycle in which the stand and the loading platform are skillfully combined and the structure of the vehicle body is simplified. The purpose.

  In addition, based on the structure of the bicycle described above, a regular traffic bicycle can be stably exercised with the rear wheel lifted from the ground while parking, even if a bicycle training device is not installed. It is a second object to provide a field exercise / bicycle that is suitable for the above.

  In order to achieve the first object, according to the present invention, in a bicycle in which a loading platform is provided above a rear wheel of a vehicle body, the loading platform is moved downward from above the rear wheel by rotation to serve as a stand. Provided is a bicycle configured to be able to lift the rear wheel from the ground.

  In order to achieve the second object, according to the present invention, in a bicycle in which a loading platform is provided above a rear wheel of a vehicle body, the loading platform is moved downward from above the rear wheel by rotation. Provided is a traffic bicycle that also serves as a local exercise bicycle that is configured to lift the rear wheel from the ground as a stand so that it can be exercised locally.

  As an embodiment of the traffic bicycle that also serves as a local exercise bicycle, the loading platform is located above the rear wheel on the rear fork of the vehicle body, and the loading position where the luggage is placed on the upper surface of the loading wheel and below the rear wheel. In this case, there is a load bed / stand combined mechanism that is pivotally supported between the upper surface and a parking position that is used as a stand against the ground.

  According to the structure of the bicycle for achieving the first object, the structure of the vehicle body is simplified by skillfully combining the stand and the loading platform.

  According to the structure of the bicycle for achieving the second object, the loading platform is used as a loading platform / stand combination mechanism so that the luggage can be placed on the upper surface or hit the ground. The contact area, that is, the ground contact area of the platform stand as a pedestal is larger than that of an ordinary leg stand, and is suitable for stable field parking and on-site exercise.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

  As shown in FIG. 1, the bicycle according to the present invention is provided with a cargo bed above the rear wheel 41 of the vehicle body 10 as in many conventional traffic bicycles. 60, that is, the rear wheel 41 is moved from the upper side to the lower side by rotation to lift the rear wheel 41 from the ground as a stand. This bicycle can be used as a local exercise bicycle because the original transportation bicycle can be used as a local exercise bicycle by such a loading platform / stand combination mechanism 60.
