JPH0752862A - Fold type handle and pedal for bicycle - Google Patents

Abstract

PURPOSE:To make the body width of a bicycle narrow, and thereby make a parking space small by providing joints at the halfway of each handle projecting to the right and left directions respectively in such a way that each handle can be bent. CONSTITUTION:The frame pipe 1 of each handle is provided with a joint 2 in such a way that the frame pipe can thereby be bent around the joint 2, and a fixing pipe 5 covering each handle pipe 1 is concurrently made freely slidable, besides, when a bicycle is run with the handle pipes 1 and 1 made in a straight shape, the handle pipes 1 and 1 are fixed in a straight shape. Moreover, a movement prevention pin 6 is provided for each fixing pipe 5 so as to be energized toward the outer circumferential surface side of each fixing pipe 5 at all times. When the handle pipes 1 and 1 are to be fixed, the movement prevention pin 6 is inserted into a pin insertion hole 9 so as to be locked. Each pedal is modified to be capable of being bent in a similar manner.

Description

Detailed Description of the Invention

[Field of Industrial Application] The present invention is to reduce the width of a bicycle body.

[Prior Art] At present, there is no one that bends the handlebar itself and the petal itself of a bicycle.

[Problems to be Solved by the Invention] Due to the structure of a bicycle, a handlebar, a saddle and the like project left and right. For this reason, when the bicycle is parked, the handlebars that protrude to the left and right and the saddle that protrudes intersect, making continuous parking difficult and requiring a large space.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to reduce the width of the bicycle body and the storage space.

[Means for Solving the Problems] In order to achieve the above-mentioned object, joints are provided in the middle of the left and right handles so that they can be bent.

Further, hinge-like joints are provided on the receiving shafts of the left and right protruding petals so that they can be folded.

[Operation] By inserting a joint in the middle of the handle and in the receiving shaft of the petal, refraction is possible.

As a result, the width of the vehicle body can be made smaller than the width of the saddle by bending the handle and the petal as shown in FIG.

[Embodiment] An embodiment will be described with reference to the drawings. The joint 2 in FIG. 1 is attached to a portion A surrounded by a dotted line of the handle 21 in FIG. 8 and the handle 2 in FIG.
It can be folded like 1.

At this time, in order to eliminate the instability of the handle 21 due to the attachment of the joint 2 and to fix the handle during traveling, the fixing pipe 5 covering the main body pipe 1 of the handle 21 covers the joint 2 as shown in FIGS. 2 and 3. Set. In this case, the stopper 4 and the movement preventing pin 6 are inserted into the hole 9 so that the fixing pipe 5 does not move, and the left and right are fixed.

A hinge 14 in FIG. 5 is attached to a portion B surrounded by a dotted line of the petal mounting crank 11 in FIG. 8 so that it can be bent like the petal 10 in FIG.

The petal 10 can be folded by removing the stopper plate 16. In order to ensure safety, a pin 17 is attached to the stopper plate so that the stopper plate 16 does not fall out.

[Effects of the Invention] Since the present invention is constructed and used as described above, it has the following effects.

By bending the handle having the bendable structure according to the first aspect, the width of the handle on the left and right is reduced.

The petal having the foldable structure of claim 2 has an effect of eliminating the left and right protrusions by folding.

Due to the effects of the first and second aspects, the bicycle body width can be reduced, the bicycle parking space can be reduced, and the bicycle can be efficiently parked.
