Abstract

(57) [Summary] [PROBLEMS] To prevent various traffic accidents and improve the quality of a bicycle by making it possible to easily identify the vehicle not only during the daytime but also especially during nighttime driving. It is in the provision of wheel rims for bicycles. A plurality of through holes (12) for inserting one end of a spoke are formed in the center of an inner peripheral surface, and an annular wheel rim (10) having a substantially U-shaped cross section for mounting a tire on the outer periphery,
At least one pair of recessed grooves 11 are formed on the inner peripheral surface of the wheel rim 10 so as to be bilaterally symmetrical with respect to the through hole 12, and the recessed groove 11 is filled with the luminescent material 20. It is characterized by that.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wheel rim for a bicycle.

[0002]

[Prior art]

 Generally, a bicycle is designed so that a user can drive by driving a pedal provided between a front wheel and a rear wheel of the bicycle, and the front wheel and the rear wheel are made of metal. It is composed of a material hub, a wheel rim of a metal material which is mounted on a tire and has a substantially U-shaped cross section, and a spoke which connects the hub and the wheel rim.

[0003]

[Problems to be solved by the device]

 Since the above wheel rims were simply made of metal material and lacked in decorative beauty, the appearance of the bicycle was not so good. In addition, when using a bicycle, especially at night, it is difficult for drivers and pedestrians of other vehicles to identify whether or not they can run, which causes various problems such as causing various accidents.

The object of the present invention is to prevent a variety of traffic accidents and improve the quality of the bicycle by making it possible to easily identify the vehicle during the nighttime as well as during the daytime. In the provision of rims.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has an annular wheel rim with a substantially U-shaped cross section, which has a plurality of through holes for inserting one end of a spoke formed in the center of an inner peripheral surface thereof and a tire is mounted on the outer periphery thereof. The at least one pair of recessed grooves are formed on the inner peripheral surface of the wheel rim so as to be bilaterally symmetrical with respect to the through hole, and the recessed grooves are filled with a light emitting material. And

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the bicycle wheel rim 10 of the present invention is a metal material that forms an annular body having a generally U-shaped cross-section that is open to the outside. A plurality of through holes 12 into which one ends of the spokes 13 are inserted are formed at regular intervals along the inner circumference. In addition, the wheel rim 10 has an inner peripheral surface formed with two pairs of left and right concave grooves 11 which are symmetrical with respect to the through hole 12 as a center. 20 is filled. The reason why the light emitting substance 20 is filled in the groove 11 is to prevent the light emitting substance 20 from peeling off due to a cleaning work of the bicycle or an external impact.

Although two pairs of concave grooves 11 are formed in the above embodiment, one pair of concave grooves may be formed, or three or four pairs of concave grooves may be formed. Then, when two or more pairs of the above-mentioned concave grooves 11 are formed, the appearance of the bicycle can be further improved by filling the light emitting substances 20 having different colors. At this time, the color arrangement is, for example, cold and warm. It is desirable to select and arrange the ones with large chromaticity difference.

As shown in FIG. 1, such a wheel rim 10 has a tire 15 mounted on the outer periphery thereof and a hub 14 made of a metal material through a plurality of spokes 13 into which the plurality of through holes 12 are inserted. By connecting to the bicycle, it will form the front and rear wheels of the bicycle.

[0009]

[Effect of the invention]

 As described above, according to the present invention, particularly when driving at night, a light emission band of different color light emitting materials is formed. This is a very useful device for preventing accidents and improving the quality of bicycles.
