Abstract

(57) [Summary] [PROBLEMS] To provide a device capable of sufficiently assuring that a bicycle user can safely drive at night. The present invention provides a light reflecting surface portion (4) on a part or all of a rim (2) or a spoke (3) constituting a bicycle wheel (1).
Is provided.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a safety device installed on a bicycle.

[0002]

[Prior art]

 In the past, some bicycles were equipped with a light reflecting plate on the rear wheel cover and a part of the pedals for safe driving at night, but in the former case, drivers of subsequent cars In the latter case, it was often only possible to identify a stationary state, and in the latter case, it was often hidden by shoes. However, the installation of such reflectors did not guarantee the safety of bicycle users.

[0003]

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to install a device that can sufficiently guarantee the safety of a bicycle user who has eliminated such disadvantages.

[0004]

[Means for Solving the Problems]

 In the present invention, a light reflecting surface is provided on a part or all of a rim or a spoke constituting a wheel of a bicycle.

[0005]

[Embodiment of the invention]

 Since the bicycle has a light reflecting surface on some or all of the wheel rims and / or spokes, when driving on a night road, the driver of the car behind it must be You will be witnessing the wheels, so you will drive with sufficient attention.

As described above, the driver of the automobile can recognize the continuously reflected light from the object (bicycle) running ahead.

【Example】

 In the present invention, there are an embodiment (1) in the case of newly establishing a bicycle manufacturing plant and an embodiment (2) in the case of an existing bicycle already used.

The case of the embodiment (1) will be described.

In this case, a part or all of the rim 2 and / or the spokes 3 constituting the bicycle wheels 1 and 1 form the light reflecting surface portions 4 and 4 by painting or other means.

When the light reflecting surfaces 4 and 4 are provided on a part of the rim 2 and / or the spokes 3, the light reflecting surfaces 4 and 4 are provided at intervals at five locations.

Reference numeral 5 denotes a tire, and reference numeral 6 denotes a tire cover.

An embodiment (2) will be described.

When installed on an existing bicycle, a sticker or sheet 7 having a light reflecting surface 4 ′ is provided on the surface of the rim 2, and through holes 8, 8 are provided in portions corresponding to the spokes 3, 3. Cuts 9 and 9 are provided in the vertical direction between the outer end portion and the cuts 9 and 9, respectively. (See Fig. 3)

However, since the spacing between the spokes differs from manufacturer to manufacturer and is not necessarily constant, the sticker or sheet 7 having a light reflecting surface is replaced with the portion including the through holes 8 and 8 and the cuts 9 and 9. Alternatively, the sticker or sheet 7 may be prepared with the width portions 10 and 10 formed between the upper and lower outer ends while leaving the central portion 7 '. (See Fig. 4)

The sticker or sheet 7 having the above structure is attached to the surface of the rim 2 at an appropriate interval.

[0016]

[Effect of the invention]

 Thus, the present invention can sufficiently convey the road conditions to the driver of a car traveling backward by seeing the reflected light exerted by the continuously rotating wheels by the bicycle user in the forward direction. The practical effect is great as it provides a good sign to prevent the occurrence of car accidents on bicycles driving at night.
