Description

[Detailed description of the invention] The purpose of this invention is to prevent fingers from getting caught near the folding hinges of a pair of frame members when folding a folding bicycle. It is covered with a film to prevent fingers from getting into the hinge section or the area where the frame members stack.

The area near the hinge part is where you place your fingers to perform the folding operation, so it's easy to get your fingers caught, and if your fingers are caught, the weight of the vehicle will be concentrated here, which could cause a bigger injury than expected. be.

The present invention is proposed to prevent such dangers, and embodiments of the present invention will be described with reference to the drawings.

In the present invention, a pair of frame members of a rotating hinge part of a folding bicycle, for example, a vertical pipe 5 and an upper pipe 7, are wrapped and wrapped with a soft film 1, and adhesives are provided at appropriate locations on the film 1. This invention relates to a safety cover for a folding bicycle that is used by being attached and fixed to a frame member through a fitting part 2.

Here, the main parts of the folding bicycle frame using the safety device of the present invention will be briefly explained. A vertical pipe 5 is rotatably supported on the main pipe 4. A shaft 6 is provided above the vertical pipe 5 with a bracket or the like, and an upper pipe 7 and an upper back hawk 8 are rotatably supported on this shaft 6. , forming one hinge part. The other end of the upper backhawk 8 is pivotally supported by a joint shaft 11 of a locking plate 10 fixed to the lower backhawk 9.

The safety device of the present invention, as shown in FIG. 3, covers the vicinity of the hinge portion of a folding bicycle frame during assembly with a film. As shown in FIG. 1, the vertices of the film 1, which has a substantially pentagonal developed shape, are designated as A, B, C, D, and E, respectively, and the midpoint thereof is designated as F. Now, attaching parts 2 made of, for example, double-sided adhesive tape are provided in advance on two sides of this film 1, and the bisector of this film 1 is aligned along the ridgeline of the upper pipe 7. Wrap the upper pipe 7 and the vertical pipe 5 near the hinges by folding them into two pieces, and attach the double-sided adhesive tape prepared in advance on the side of the film 1 to the surface of the vertical pipe 5, and attach the film 1 to the frame member. It is pasted and fixed with a slight tension along the sides to form an annular shape. In addition, if necessary, a part on the line bisecting the film 1 along the ridgeline of the upper pipe 7, preferably A
By providing the adhesive portion 2 near the point, the film 1 can be securely fixed to the frame member.

Note that there are so-called caution marks 3 on the surface of the film 1, such as explanatory notes on how to operate the film, or instruction pictures that serve as a guide to the operating position and method.
If you write , caution mark 3 will appear on the side of the bicycle, and if the film material is transparent,
The caution mark 3 stands out even more firmly, making it possible to draw the operator's attention. FIG. 1 shows an embodiment in which instruction pictures are written on the surface of the film.

In the present invention, as described above, when the bicycle is assembled and used, the film 1 is stretched along the pipe 7 and the vertical pipe 5 in an annular shape and has a substantially triangular shape when viewed from the side, and the locking plate 10 is stretched in the direction of the arrow in FIG. When you press and perform the folding operation, the bicycle will move to the 4th position.
It can be folded as shown in the picture. The upper backhawk 8, the lower backhawk 9, the vertical pipe 5, the upper pipe 7, etc. are bent and rotated about their respective hinge portions to be in a folded state. In this case, since the film 1 wrapped around the vertical pipe 5 and the upper pipe 7 is made of a soft material, it is deformable and does not pose any obstacle to folding. Even when the vehicle is stacked, the film 1 is placed on the hinge where the weight of the vehicle is concentrated.
Since there is an intervening part, it is possible to prevent fingers from getting caught and causing serious injury.

As described above, according to the present invention, it is possible to provide a safety cover for a folding bicycle that allows the folding operation of the folding bicycle to be carried out safely and also that can easily display operating procedures.
