Claims (4)

1. A caster device comprising a circular tire portion that makes contact with the ground, a circular wheel portion provided inside the tire portion to support the tire portion, and a shaft portion provided at the center of the wheel portion to rotatably support the tire portion and the wheel portion, characterized in that a phosphorescent material is provided on the wheel portion.
2. The caster device according to claim 1, wherein the wheel portion is molded from a material containing the phosphorescent agent.
3. The caster device according to claim 1, wherein a phosphorescent member molded from a material containing the aforementioned phosphorescent agent is attached to the wheel portion.
4. The caster device according to claim 1, wherein a wheel cover molded from a material containing the phosphorescent agent is detachably provided on the wheel portion.

Description

This invention relates to a caster device. Conventionally, caster devices have been made of synthetic resin or metal materials that do not have phosphorescent properties. As a result, handcarts equipped with such casters are difficult to see even when left unattended at night, and there is a problem that cars attempting to park may collide with handcarts parked in parking lots, causing damage to both. Utility Model Registration No. 3168089 Gazette This is a front view of a handcart fitted with the caster device of the present invention.This is a front view of the caster device of the present invention. The embodiments for implementing this invention will be described in detail below with reference to Figures 1 and 2. The caster device 1 is a caster device consisting of a circular tire portion 2 that makes contact with the ground, a circular wheel portion 3 provided inside the tire portion 2 to support the tire portion 2, and a shaft portion 4 provided at the center of the wheel portion 3 to rotatably support the tire portion 2 and the wheel portion 3, wherein a phosphorescent material 5 is provided on the wheel portion 3. The wheel portion 3 is molded from a material containing phosphorescent material, and the effect of phosphorescence is enhanced when the surface area is larger than that of the tire portion 2. The wheel portion 3 is molded from a material containing phosphorescent material 5. Although it has been explained that the wheel portion 3 is molded from a material containing phosphorescent material, the wheel portion 3 may also be detachably provided with a wheel cover molded from a material containing phosphorescent agent 5, and it is preferable that the wheel cover be the same size as the wheel portion 3 to avoid any sense of incongruity. The tire portion 2 is preferably made of a rubbery material, but may also be made of a synthetic resin material. The wheel portion 3 is formed by injection molding from a synthetic resin material made of polypropylene resin. The shaft portion 4 has a through hole 7 into which the support shaft 6 is inserted, but a shaft (not shown) may be provided instead of the through hole 7. The phosphorescent material 5 stores light (electromagnetic waves) and emits light even after light irradiation stops; strontium aluminate is commonly used. It is usually a milky white color that is nearly colorless. The caster device 1 can be used as a caster device for shopping carts, mobility scooters, carry bags, transport cases, tricycles, and toys. The wheel portion 3 glows in the dark, such as in a room after the lights are turned off or at night, making the item to which the caster device 1 is attached visible. Figure 2 is a front view of the caster device 1 with a phosphorescent member 8 attached to the wheel portion. The phosphorescent member 8 is molded from a material containing phosphorescent material and is attached to the wheel portion 3.
