Description

Description Bicycle open / close type handle unit Technical field

TECHNICAL FIELD The present invention relates to a handle unit for detachably attaching to a handlebar of a bicycle. The handle unit has two openable and closable handles, and the two handles have an angle of approximately zero degree and approximately 180 degrees. The present invention relates to an openable and closable handle unit that can be adjusted to any angle between degrees. Background art

A foldable handle for narrowing the width of the bicycle, reducing the storage space for the bicycle, and facilitating the storage of the bicycle is disclosed in Japanese Patent Application Laid-Open No. H10-1199686 and Japanese Patent Publication No. This is disclosed in Japanese Unexamined Patent Publication No. Hei 7-5-26283.

In these conventional folding handles of bicycles, the handles are fixed with the handles opened to the left and right, and when storing the bicycle, the handles are folded in a direction parallel to the bicycle. For this reason, it has been difficult to fix the left and right handles symmetrically at a desired angle between the opened state and the closed state.

The main object of the present invention is to provide a closed state in which the left and right handles of the bicycle are at an angle of 0 degree to each other, that is, a state in which the left and right handles are folded, and an open state in which the mutual angle is approximately 180 degrees. Between the left and right steering wheels so that the left and right steering wheels swing symmetrically in tandem with each other so that they are at the same angle with respect to the bicycle. The purpose of the present invention is to make it possible to easily adjust the angle of the steering wheel.

Another object of the present invention is to enable the bicycle to be easily attached to an existing bicycle handle attachment portion. Disclosure of the invention In the present invention, a bracket is fixed to the holder, and a mounting pipe is fixed to the bracket. This mounting pipe can be freely inserted into the hole for attaching the handle of the existing bicycle handle post, and can be fixed to this hole. The holder supports a pair of gears of the same diameter so that they can rotate in a mutually meshed state. Further, the holding member supports a locking member having a gear portion for hooking at a part thereof so as to be movable in a direction facing the pair of gears and moving toward and away from the pair of gears. Further, the holding body includes a locking body operation mechanism for moving the locking body in a direction engaging with the pair of gears and for moving the locking body in a direction away from the gears. A pair of handles of the same length are folded parallel to and close to each other, and each end is fixed to a corresponding pair of gears. When the locking body operating mechanism is operated to release the locking body from the pair of gears and release the engagement of the locking body with the pair of gears, the pair of gears can rotate in conjunction with each other. Becomes In this state, when the pair of handles is opened to the left and right, the pair of handles cooperate with each other and move while maintaining a symmetric position with respect to the bicycle. After setting the pair of handles to an arbitrary angle within the range where the mutual angle is approximately zero degree and approximately 180 degrees, operate the locking body operation mechanism to convert the locking body to a pair of gears When the engaging portion of the locking body is engaged with the pair of gears by crimping, the pair of gears is fixed to the holding body side via the locking body, and the handle connected to the pair of gears is attached to the bicycle. While being held at the same angle, they are fixed to the holder at an arbitrary angle. The locking body operation mechanism includes a screw hole formed in a rear wall of the holding body, and a screw that is screwed into the screw hole, a knob is fixed to a rear portion, and a distal end portion engages with the locking body. The movement of the screw in the forward and backward directions due to the rotation of the screw causes the locking body to move in the direction of pressing the pair of gears and in the direction away from the force of the pair of gears, thereby fixing and releasing the fixing of the pair of gears. Done. Although a variety of shapes can be adopted for the pair of handles, it is most preferable to use a straight metal pipe. BRIEF DESCRIPTION OF THE FIGURES
