Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a locking device that temporarily locks the rotation of a bicycle handle when the bicycle is parked.

(Conventional technology) When temporarily parking a bicycle with luggage in the front basket while shopping, if the parking place is sloped or the luggage is too heavy, the handlebar may turn significantly to the right or left. As a result, the front wheel often moves and the bicycle falls over.

In response to this problem, various types of handle locking devices have been proposed.

(Problem that the invention aims to solve) However, these devices have complicated structures, require time and effort to lock and release the handlebars, and have high production costs. Many devices are not suitable for locking devices for handlebars when parking bicycles.

In view of the above-mentioned circumstances, the object of this invention is to develop a bicycle handle locking device that can easily lock and release the handle, has a simple structure, and can be manufactured at low cost.

(Means for solving the problem) In order to solve the above problem, in this invention, the base end of the stopper stay is pivoted to the front fork side,
On the other hand, the present invention proposes a temporary rotation locking device for a bicycle handlebar, in which the receiving portion of the stopper stay is made of an elastic member and is attached to the lower pipe side of the frame.

(Function) In other words, in this invention, the rotation of the handle is easily stopped by inserting the tip of the stopper stay pivotally attached to the front fork side into the receiving part made of an elastic member attached to the lower pipe of the vehicle body frame. If the handle is forcibly rotated, the tip of the stopper will come off the receiving part and the handle will be easily released.

(Embodiment) The following invention will be explained based on the illustrated embodiment: 1 is a left front fork of a pair of left and right front forks, 2 is a head tube, 3 is a lower pipe of the vehicle body frame, Although not shown in the drawings, a handle post is rotatably attached to the head tube 2 as is well known.

On the other hand, 4 is a stopper stay whose tip is bent into an L shape to form a locking part 4a, and a bolt 6 is inserted into the base end of the stopper stay 4 through washers 5, 5. Further, a spacer 7 is provided on the bolt 6, and a spring 8 is wound around the spacer 7, so that the rotation of the stopper stay 4 is biased in one direction by the spring 8. Further, the bolt 6 is provided with an attachment band 9 for attaching it to the front fork of the stopper stay 4, and furthermore, a nut 10 for tightening the attachment band 9 is provided at the end of the bolt 6.

In this embodiment, the stopper stay 4 is attached to the left front fork 1 by an attachment band 9, but it may be attached to the right front fork.

Reference numeral 11 denotes a receiving part for the stopper stay 4 made of a natural or synthetic elastic member, and the receiving part 1 has a locking groove 11a for a locking part 4a formed at the tip of the stopper stay 4. Furthermore, a bolt 13 is attached to the base end of the receiving portion 11 via washers 12, 12.
is inserted, and the attachment band 14 to the lower pipe 3 is fixed to the bolt 13.

In this embodiment, the receiving portion 11 is attached by an attachment band 14 to a position on the lower pipe 3 corresponding to the attachment position of the stopper stay 4 described above.

This invention is constructed as described above, and its usage is as follows: After stopping the bicycle and setting up the stand, with the handlebar facing slightly to the left, the locking part 4a of the stopper stay 4 is attached to the receiving part 11. Insert it into the locking groove 11a from above and lock it.

When the bicycle is locked in this way, since the bicycle has been stopped with the handlebars tilted slightly to the left, the front fork 1 tries to rotate to the left due to the weight of the luggage in the front basket, but this force is absorbed by the stopper stay. 4
The bicycle is supported by the bicycle and does not rotate any further, thus preventing the bicycle from falling over.

In this embodiment, the receiving portion 11 is attached to the lower pipe 3 corresponding to the mounting position of the stopper stay 4.
Since the stopper stay 4 is installed in the position shown in FIG.

On the other hand, when starting the vehicle, when the steering wheel is turned to the right from the current state, the locking portion 4a of the stopper stay 4 is disengaged from the opening of the locking groove 11a, and the stopper stay 4 is rotated by the bias of the spring 8. Since the vehicle is moved and stopped at a position along the front fork 1, it can continue traveling in that state.

Also, while the vehicle is running, the stopper stay 4 is pressed against the front fork 1 side by the force of the spring 8, so the vehicle can run safely without getting caught in the front wheels.

In this embodiment, the stopper stay 4 and the receiving part 11 are attached to the front fork 1 and the lower pipe 3 by the attachment bands 9 and 14, but they may be attached directly.

(Effects of the invention) In summary, with this invention, the tip of the stopper stay pivoted on the front fork side is inserted into the receiving part made of an elastic member attached to the lower pipe of the vehicle body frame, thereby making it possible to easily rotate the handle. is locked, and if you forcibly turn the handle, the tip of the stopper will come off the receiving part and the handle will be easily released, so you can park your bicycle with your luggage in the front basket when shopping. It is extremely effective in preventing falls when

Furthermore, the locking device of this invention has a simpler structure than conventional locking devices and can be manufactured at extremely low cost.
