Description

  The present invention relates to a portable bicycle stand.

  2. Description of the Related Art Conventionally, various types of support systems are known as portable bicycle stands that allow a bicycle without a stand to be parked independently. For example, the upper end portion of each leg member is a hub nut so that a pair of leg members obtained by bending a bar orthogonal to the surface of the wheel in a U-shape may be extended back and forth with the hub shaft of the wheel as a common support shaft. There is known a bicycle stand configured to be fitted to the outside of a nut (see, for example, Patent Document 1). This bicycle stand is used by expanding the upper end of the U-shaped leg with both hands and fitting it on both ends of the hub axle.

  In addition, a bicycle stand is known in which two upper and lower hooks are provided on a post erected on the side of the rear wheel, and each hook is made to support the seat stay and the chain stay of the bicycle (for example, Patent Document 2). The bicycle stand is used by placing the bicycle next to the stand and lifting the bicycle up and down to hang each stay on the upper and lower hooks.

  Further, as shown in FIGS. 5 (a) and 5 (b), there is known a bicycle stand that supports the wheel so as to be sandwiched from both left and right sides of the wheel. The bicycle stand 9 includes a pair of left and right portals 91, and a pair of front and rear leg members 92 connected to the front and rear lower ends of the two portals 91. The leg member 92 is formed by connecting a rod to be able to open and close in the left and right directions by the pivot shaft 9 a, and the middle part of each rod is connected to the lower end of the portal member 91. When the wheel stand 10 is placed on the upper part of the pivot shaft 9a of the leg member 92 from between the gate-shaped members 91, the lower part of the leg member 92 is opened by the load of the wheel. The upper part approaches and pinches the wheel.
