Abstract

A folding bicycle that can be further folded so as to have a smaller volume is provided.
A folding bicycle includes a head and a frame. The head includes a handle bar, a handle stem, a folding connecting portion, and a front fork. Two fork blades 141 are provided. Thus, when the handle bar is folded downward together with the handle stem, the handle bar is further folded and placed in the recess of the fork blade without interfering with the fork blade.

Description

  The present invention relates to a folding bicycle, and more particularly to a front fork of a folding bicycle.

  Folding bicycles are required to be folded smaller. In order to reduce the volume of the folded bicycle when it is folded, a folding connecting portion is usually disposed under the handle stem of the folded bicycle. Thereby, the handle bar can be folded downward together with the handle stem, and after being folded, the handle bar is placed on the fork blade of the front fork.

  However, since the fork blade of the front fork is a straight tube when viewed from the front, the handle bar is supported tilted when placed on the fork blade. Therefore, the folding bicycle cannot be folded any further, and the volume when folded is still relatively large.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a folding bicycle in which the handlebar does not interfere with the fork blade so that the volume becomes small when folded.

  A folding bicycle according to the present invention includes a head and a frame, and the head includes a handle bar, a handle stem, a folding connecting portion, and a front fork, and the front forks are recessed inward. It is characterized by having two fork blades.

  In the folding bicycle according to the present invention, the fork blade of the front fork is recessed inward, so when the handle bar is folded downward together with the handle stem, the handle bar does not interfere with the fork blade and does not interfere with the fork blade. Can be set. Therefore, the folding bicycle can be further folded to reduce the volume.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the folding bicycle according to the embodiment of the present invention includes a head 1 and a frame 2, and the head 1 includes a handle bar 11, a handle stem 12, a folding connecting portion 13, a front The fork 14 is provided with two fork blades 141 each recessed inward.

  As shown in FIG. 2, when the handle stem 12 is in the folded state, the handle bar 11 can be further folded and placed in the recess 142 of the fork blade 141 without interfering with the fork blade 141. Therefore, the folding bicycle can be further folded to reduce the volume.

  Because the handle bar 11 is placed in the recess 142, collisions and friction between the handle bar 11 and the recess 142 may cause surface destruction or scratches in the handle bar 11 and the recess 142. In order to prevent damage to the surface, as shown in FIG. 3, a protective pad 143 made of an elastic material such as plastic, rubber, and a compound of rubber and plastic covers the recess 142 of the front fork of the folded bicycle. When the handle bar 11 is folded downward together with the handle stem 12, the handle bar 11 does not directly contact the concave portion 142 of the fork blade 141, so that the surfaces of the handle bar 11 and the fork blade 141 are sufficiently protected.

  As shown in FIG. 4, the folding bicycle according to another embodiment of the present invention further includes a fastener 3 on the frame 2, a hook 4 on the handle stem 12, and when the handle bar 11 is folded downward. The hook 4 can be fitted to the fastener 3. When the handle stem 12 is folded downward, the hook 4 is tightly fitted to the fastener 3 so that the handle stem 12 and the handle bar 11 are sufficiently fixed, and the handle stem 12 and the handle bar 11 are folded. Prevent shaking.

  In the above-described embodiment, the present invention has been described as a desirable specific example. However, it should be understood that the present invention is not limited to this. On the contrary, it should be intended to encompass various modifications and similar arrangements and configurations. Accordingly, the scope of the appended utility model registration claims should be given as the broadest interpretation so as to encompass all such variations and similar arrangements and configurations.

It is the schematic of the folding bicycle shown as one embodiment of this invention. It is the schematic when the folding bicycle shown in FIG. 1 is folded. It is the schematic of the front fork of the folding bicycle shown in FIG. It is the schematic of the folding bicycle shown as other embodiment of this invention.
