Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a safe and inexpensive handle folding mechanism for use in folding bicycles.

Conventional Structures and Their Problems Conventionally, in many cases of folding automobiles, the vehicle body is folded and the steering wheel is also folded to make the entire vehicle compact. The handle can be folded by placing the handle at the mounting portion of the handle post, loosening the mounting screw, and rotating the handle. A conventional handle is shown in FIGS. 1 and 2, and a handle post is shown in FIG.

Reference numeral 1 denotes a handlebar, and grips 2, 2 are attached to the ends thereof. The entire handlebar is curved in a U-shape, and the center part 3 of the handlebar is thicker in diameter than the other parts, and the entire circumference of this part is knurled to prevent it from rotating easily when tightened. I have to.

Reference numeral 4 denotes a handlebar post, which has a handlebar fitting part 5 and ears 6, 6 for tightening the fitting part at its front part. 7 is a fastener provided on the ear piece, and has a handle 8. In addition, the length of the handle 8 of the fastener 7 is made long so that it can be tightened with bare hands without using a separate tool.

As described above, in the configuration in which the center part 3 of the handlebar 1 is fitted into the fitting part 5 of the post 4 and tightened, there is no restriction against misalignment of the handlebar post in the left and right direction, and during the folding operation. In addition, there is a risk that the center portion 3 of the handlebar may shift from the post. This misalignment results in poor left-right balance, which adversely affects steering wheel operation, and
Fixation is also uncertain and extremely dangerous. Further, during folding and assembly operations, it is necessary to monitor or shift the device to prevent this from happening, which is disadvantageous and requires extra labor.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and aims to provide a structure in which the handle does not shift from side to side during folding and assembly.

Structure of the Invention In order to achieve the above object, the handle device of the present invention has a stopper fixed to the handle to prevent the handle from shifting from a predetermined position in the left and right direction.
The side of the post serves as its guide.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 4 and 5, 10 is a handlebar, and a grip 11 is attached to the end of the handlebar. The entire handlebar 10 is curved in a U-shape, and the central part 12 of the handlebar 10 is thicker in diameter than the other parts, and the entire circumference of this part is knurled to prevent it from rotating easily when tightened. I have to. Reference numeral 13 denotes stoppers, two of which protrude from the thick diameter part at the center of the handlebar, that is, just beside the fitting part with the post, and are made of steel wire with a circular cross section.

14 is a handle post, and 15 is an upper post, which allows the center part 12 of the handlebar 10 to be
It is something that catches the eye. Numeral 16 is a bolt that connects the front sides of the post 14 and the upper post 15, and 17 is a fastener that tightens the rear sides of both, and has a handle 18. 19 is a pipe connected to the bicycle head.

As shown in FIG. 6, the two stoppers 13 are attached to both sides of the center portion 12 of the handlebar 10 with the lower post 14 sandwiched between them. In this example, holes are drilled in the handlebar 10. The end of the stopper 13 is fitted into this hole and fixed by welding. And stopper 13
As shown in Figures 5 and 7, when the handle is set at the most suitable angle for use, the upper post 1
It is set so that it comes into contact with the lower end of 5.

Hereinafter, the effects of the above configuration will be explained. When set up for use, the handle shown in FIG. 4 has the center portion 12 sandwiched between the upper post 15 and the post 14, and the fastener 17 and bolt 1, as shown in FIG.
Tighten and fix at step 6. Since the stopper 13 is brought into contact with the lower end of the upper post 15, even if the handle fastener 17 loosens, the handle cannot rotate in the direction of arrow B in FIG.
Direction B corresponds to the forward direction of the bicycle. It can be rotated in the opposite direction of arrow A, and when folded,
Rotate the fastener 17 with the handle 18, loosen it, and turn the handle. At this time, the stopper 13 is located immediately on the side of the upper post 15 and post 14, so
No matter how many times the handle is rotated, the center portion 12 will not shift from the post portion. In addition, bolt 16
is fixed to a certain size, and the post is tightened or loosened from the handle using a tightening tool.

In the embodiment, the stopper is composed of two rods, but as shown in FIG. 9, it may be U-shaped so as not to interfere with the post 14 when the handle is rotated. In this case, as shown in FIG. 8, the abutting portion of the stopper 13' is on the lower side of the post 14.

It is also possible that the post is not made up of two parts. In this case, if the opening dimension S of the fitting part shown in FIG. 3 of the conventional example is made larger than the diameter a of the stopper shown in FIG. The handle can be set in its normal position by passing through the opening.

Effects of the invention According to the invention, the following effects can be obtained.

1. Since stoppers are provided on both sides of the post to protrude from the handle, the handle does not shift even when the handle is rotated repeatedly during the folding operation, and the fixation is reliable and the handle is easy to operate.

2. By applying the stopper to a part of the handle post at a predetermined position and regulating the rotation angle, the handle can be prevented from rotating in the event of a collision, and a powerful safety device can be constructed with a simple shape.
