[Structure] The handle used for driving is fixed to the handlebar of the bicycle, and the handle is divided into two parts, left and right, and the toothed plate using the meshing of gears is fixed to the tip of the center of the handle, and the handle fixing and tightening device is attached. Fold the handle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handle device used for driving a bicycle.

[0002]

[Prior art]

 Various types of bicycle handle devices have been conventionally proposed. For example, there is one that folds by rotating the handle 90 degrees horizontally in the direction of the front wheel, or one that folds horizontally by 45 degrees inside with two right and left handles and two folding fulcrum fittings in the center.

Therefore, according to the former, there is an advantage that the occupied area of the width is smaller than the conventional one when the bicycle is stored, but the length is not changed. On the other hand, according to the latter, the occupied area of the width is about 1/3 and the length is about 1/2, and the storage area is reduced.

[0004]

[Problems to be solved by the device]

 However, on the latter side as the above-mentioned conventional proposal, the opening / closing operation requires loosening the handle for fixing the handle in two places on the left and right and folding the left and right handles twice inward. When opening, it is necessary to perform the reverse operation. If a safety device with a fixed handle is attached to prevent danger, the operation becomes complicated.

The present invention was devised to simplify the complicated operation described above. The purpose of the present invention is to keep the handle length and width safe and to reduce the storage area of the bicycle. It is to provide a handle refitting that can be folded by a simple operation.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the structure of the folding handle of the bicycle of this invention is characterized by dividing the left and right handles into two parts and providing a member with a gear carved at the tip of the center part, so that the left and right tooth shapes mesh with each other. That is the case.

[0007]

[Action]

 Therefore, loosen the handle fixing tightening / loosening knob attached to the upper lid of the center part of the bicycle handle, remove the tightening screw, and fold either handle on the inside to complete the folding operation of the handle. . Further, in the series of folding operations described above, it is preferable to rotate the handle fixing tightening / loosening knob with the right hand to release the tightening screw, lift the upper lid forward, and fold the left handle inward with the left hand. Also, when tightening after folding, the screw holes do not necessarily have to be fixed by tightening because the upper part of the fixing plate is free and the lower part is the screw part. On the other hand, in order to make the handle folded as described above usable, it is sufficient to reverse the above series of operations.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. As shown in FIGS. 1 and 2, a folding device for a bicycle according to an embodiment of the present invention includes a handle post that is inserted into a front pipe of a bicycle. It has a fixed plate 2 fixed to 1 and tooth profile plates 4 and 4a fixed to the handles 3 and 3a, and the tooth profile plates 4 and 4a are rotatably held by bolt nuts 5 and 5a. There is.

Further, when the handle is used, the tooth-shaped plates 4 and 4a hit the side faces 6 and 6a of the fixed plate 2 so that the handles 3 and 3a do not go forward. At the front end of the fixed plate 2, an upper lid 7 that can be opened and closed is provided on a spring 8 that exerts an inward force.

A hole is made in the center of the rear surface of the upper lid 7, and a handle fixing tightening / loosening knob 9 and a tightening screw 10 are rotatably fixed. An upper stage hole free and a lower stage screw hole 11 are provided, which consists of two layers in which the tightening screw 10 is inserted in the central portion of the fixing plate 2. The handle fixing pins 12 and 12a are fixed to the inside of the upper lid 7. The toothed plates 4 and 4a are provided with fixing pin holes 13, 13a and 14 and 14a into which the fixing pins 12 and 12a are inserted, and further, when the handles 3 and 3a are opened and closed, the fixing pins 12 and 12a smoothly move from the fixing pin holes 13 and 13a. Fixing pin grooves 15 and 15a are provided so as to enter into 14 and 14a or 14 and 14a to 13 and 13a.

The present invention is configured as described above, and the operation method will be described in order from the fixed state. When the handle fixing tightening / loosening knob 9 is rotated to the left with the right hand, the fixing is released. The upper lid 7 is slightly lifted up as it is so that the fastening screw 10 is separated from the screw hole 11 from the fixing plate 2. Fold the handle 3a lightly inward with your left hand, and release the handle fixing loosening knob 9 with your right hand. The fixing pins 12 and 12a will enter the fixing pin grooves 15 and 15a. When the upper lid 7 is closed by the force of the spring 8 and the fixing pins 12 and 12a enter the fixing pin holes 14 and 14a, the folding operation of the handle is completed. Further, by further turning the handle fixing and tightening and loosening knob 9 to the right with the right hand, it can be fixed in the folded state. On the other hand, in order to bring the folded handle as described above into the open state in which it can be used, it is sufficient to reverse the above series of operations.

[0012]

[Effect of device]

 As described above, according to the present invention, it can be used for any bicycle such as a folding bicycle or a home bicycle, and has an advantage that the bicycle parking space around a train station in an urban area is relaxed. However, it is easy for both women and women to operate at home and has the advantage that the bicycle can be stored in a small area.
