[Detailed description of the invention]

[0001]

[Industrial application] This invention is used for transportation or storage .
The present invention relates to a folding bicycle capable of reducing the installation area.

[0002]

2. Description of the Related Art Conventionally, in a folding bicycle, for example, an upper pipe and a lower pipe for connecting a head pipe and a standing pipe, or upper and lower pipes thereof, are provided with a folding joint in the middle of a single pipe. There is also a type in which the frame is folded in the horizontal direction about the vertical axis arranged on one side of the bending joint, and the frames are juxtaposed on the left and right.
As described in JP-A-59-139480,
Between the main pipe connecting the pad pipe and the hanger
The horizontal pivot on the lower side, and the lock bracket on the upper side.
Each can be folded vertically around the axis,
Bend the top pipe from the middle to the head pipe side
Approach, and then fold it vertically at the rear end of the rear carrier and stand
It has been proposed to maintain standing.

[0003]

In the case of the above-mentioned type of folding in two in the horizontal direction, the length in the front and rear direction is certainly reduced to ２ because it is arranged in two rows on the left and right, but the reduced portion is expanded horizontally. Therefore, the width is doubled, and the storage floor area does not change.

[0004] In addition , a tab that folds vertically to the seat pipe.
In the case of Ip, the connection structure is complicated and the cost is high
In addition, there is a disadvantage that rattling occurs.

This invention is based on a head pipe, hanger and
Is in the middle of the main pipe that communicates with the standing pipe,
It is connected by a bending joint provided by a pivot axis on which a shaft center is disposed horizontally on the lower side and a lock fitting on the upper side ,
The whole can be placed vertically stand and thereby reduce the overall length by bending the opening before basket attached from the intermediate to the forward longitudinal direction of maintaining upward state, as much as possible the parking floor area It is intended to be easily stored in ordinary households.

[0006]

Placed on the main pipe intermediate to contact the head pipe and the hanger or stand pipe In order to solve the problems]
And a pivot axis on which a shaft center is arranged horizontally on the lower side, and an upper side
Connected by a bending joint provided from the lock bracket of
When the lock bracket is locked, the main pipe is
When the lock is unlocked, the main pipe can be vertically bent to maintain the opening of the basket in front of the main pipe from the middle, centering on the pivot, and surface contact and both stand and the rear key catcher rear, and lock lever notch of the mounting portion of both the stand
The engaged, to lock on the lift-up state, the entire force standing
In the folding bicycle, characterized in that it is configured to possible.

[0007] The second half of the bending joint mounting position
Hands are placed on the second half of the main pipe and the vertical pipe.
Is also good.

[0008] The handle may be provided from a band.
is there.

[0009]

[Action] The invention is bent into the folded longitudinal from the middle of the main pipe to contact the head pipe and the hanger or stand pipe from configured as described above, folding no front wheels and rear wheels in a state to be connected a space-saving in the.

[0010] With the vertically bent joint and its position, the front cage opening can be turned upward when standing up, and the accommodation portion can be installed. Those good stability since supported by late catcher rear and both stand electromotive Tatsutoki.
