Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bicycle spoke cover that allows a running bicycle to be easily confirmed from a distance at night or in a dark place.

[0002]

[Prior art]

 In conventional bicycles, lights for night driving are provided in front of the bicycle such as a steering wheel, a front pipe or a front hawk. However, the lights running at night are like “points” that do not move from a distance, and are not noticeable from the viewpoint of accident prevention. A reflective material was attached to a part of the pedal as a means to make the existence of a running bicycle noticeable, but the light was seen and hidden by the foot, and it was not enough light to be confirmed by human eyes.

[0003]

[Problems to be solved by the invention]

 By attaching a cover to the spokes of the bicycle, the present invention emits light with movement while traveling, allowing pedestrians and automobiles to easily recognize the bicycle while it is traveling, and it is faster than before. The avoidance action can prevent accidents, and the cover of the spokes is intended to provide a product in which an arbitrary number of favorite colors can be attached to enjoy the decorativeness.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a cylindrical or polygonal cover body made of a synthetic resin having a through hole whose inner diameter is the same as or slightly larger than the spoke outer diameter of a bicycle, along with the longitudinal direction of the cover body. The cover has an attachment / detachment slit that communicates with the through-hole, and the outer circumference of the cover body is covered with a reflective or luminescent material.When the wheel is equipped with any number of spoke covers, the cover will be attached to the outer circumference of the wheel by centrifugal force. It is located at, and glows while rotating as the wheels rotate, and can be easily confirmed from a distance even at night.

[0005]

[Embodiment of the invention]

 The spoke cover of the bicycle according to the present invention makes it possible to easily recognize the bicycle from a distance even in a dark place or at night because the cover that rotates together with the wheels reflects light while the bicycle is running.

The cover body is formed of a columnar body formed by extruding a hard synthetic resin, and has a through hole having an inner diameter that is the same as or slightly thicker than the outer diameter of the spokes of the vehicle in the central shaft portion. Slits for attachment / detachment are formed on the outer circumference of the cover body. The slit extends along the longitudinal direction of the cover body, that is, the through hole, and communicates with the through hole. The slit width of the slit of the cover body is formed such that the outer peripheral side is wider than the through hole side.

The outer circumference of the cover body is covered with a reflective or luminescent material. As the reflective material, a reflective sheet that reflects light from automobile lights or streetlights, or a luminous sheet that stores and emits the emitted light is used. Similar effects can be obtained by applying a paint that reflects light.

The cover body has a polygonal columnar shape such as a columnar shape, a triangular prism shape, a quadrangular prism shape or the like, or one or more blades are integrally formed along the longitudinal direction of the cylindrical or polygonal columnar shape body to form a flat surface. The number of parts, that is, the reflecting surface (light emitting surface) can be increased.

Although the outer diameter of the spoke differs depending on the bicycle, when a synthetic resin having rigidity is used for the cover body, it can be fitted even if the inner diameter of the through hole is the same as the outer diameter of the spoke. However, it is easier to use if the inner diameter of the through hole is slightly larger than the outer diameter of the spoke. Since the spoke cover has a tapered slit, the spokes can be easily guided by the slit side wall from the wide entrance to the narrow through hole direction, and the cover once fitted on the spokes can be easily removed. Never.

When an arbitrary number of spoke covers are mounted on a wheel and the vehicle travels, the spoke cover is positioned in the peripheral direction of the wheel by centrifugal force and shines while moving with the wheel, so it is easier to stand out than stationary light and safe at night. It is effective for running. The shape of the cover body is not a columnar shape but a polygonal columnar shape, or an arbitrary number of blades are formed on a part of the outer peripheral surface of the columnar shape or the polygonal columnar shape, and the reflecting surface is projected to the front side of the bicycle. It is easy to see the light from behind, and the effect can be improved.

[0011]

【Example】

 An example will be described with reference to FIG. Reference numeral 1 denotes a cylindrical cover body formed by extruding a hard synthetic resin, and has a through hole 2 passing through the central shaft portion. The inner diameter of the through hole 2 is formed to be slightly larger than the outer diameter of the spokes of the bicycle.

Denoted at 3 is a slit for attachment to and detachment from the spoke, which is formed on the outer periphery of the cover body 1 in the longitudinal direction, that is, along the through hole 2 and communicates with the through hole 2. The opening width of the slit 3 is tapered so that it gradually narrows from the outer peripheral side opening end of the cover body 1 toward the communicating portion side with the through hole 2. Reference numeral 4 is a reflection sheet covering the outer periphery of the cover body 1, which can reflect and shine when hit by a car light or a street light at night.

Since the outer diameter of the spokes varies slightly depending on the type and manufacturer of the bicycle, it is desirable that the synthetic resin used to mold the cover body 1 has some rigidity in order to improve versatility. If the cover body 1 has rigidity, it can be mounted even if the spoke outer diameter and the through hole 2 inner diameter are substantially the same.

FIG. 2 shows another embodiment, in which the blades 5 are formed integrally with the cylindrical cover body 1. In FIG. 2, two blades 5 are formed at corresponding positions on the outer periphery of the cover body 1 along the longitudinal direction, but one or three blades may be used as long as they do not hinder the running of the bicycle. Further, the reflective material covering the outer periphery of the cover body 1 may be replaced with the reflective sheet 4 by using a luminous sheet or a paint having a reflective or luminescent property.

In the embodiment shown in FIG. 3A, the cover body 1 is formed in a triangular prism shape. In the embodiment of (B), the cover body 1 is formed in an octagonal prism shape. In the embodiment of (C), the cover body 1 is formed in a quadrangular prism shape and the blades 5 are integrally formed on both side surfaces.

In the spoke cover configured as described above, when the slit and the spoke are aligned and positioned and then pushed in, the tapered slit side wall serves as a guide to allow the spoke to fit into the through hole. Therefore, any number of spoke covers can be mounted on the wheels at appropriate intervals as shown in Fig. 4, and when traveling, centrifugal force causes all the spoke covers to slide toward the outer peripheral side. It lights up while moving and rotating, and can be easily confirmed even from a distance. Although FIG. 4 shows only the front wheels, the same operation and effect can be obtained by mounting the front wheels.

By forming the cover body into a polygonal column such as a triangular column or a square column, or by providing blades integrally with the cover body, the reflective surface of the spoke cover can be increased, and the light display of the bicycle running at night is remarkable. In that case, a more effective product can be obtained. In particular, the blades are flaring out to the side, so it is easier to check the light from the rear or front of the bicycle compared to conventional products.

[0018]

[Effect of the invention]

 Since the present invention has the above-described structure and operation, the spoke cover can be easily attached to the spoke with one hand. Also, while the bicycle is running, the spoke covers rotate around the outer periphery along with the movement of the wheels, which makes it easy for a car or pedestrian to recognize from a distance, and quick avoidance action is very safe. In addition, the reflective materials such as the reflective sheet and the luminous sheet are rich in colors, and users can attach and use as many colors as they like and enjoy the decorativeness as well as the practicality.
