Caster device

Abstract

This invention provides a caster device that solves the problem of shopping carts equipped with casters being less noticeable when left unattended at night, and of cars attempting to park colliding with the shopping carts in the parking lot, causing damage to both. [Solution] A caster device 1 comprising a circular tire portion 2 that makes contact with the ground, a circular wheel portion 3 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, wherein a phosphorescent material 5 is provided on the wheel portion.

Description

Technical Field

[0001] The present invention relates to a caster device.

Background Art

[0002] Conventionally, caster devices are made of synthetic resin materials or metal materials without a light storage function. Even if a handcart equipped with the caster device is left unattended at night, it is not easily noticeable, and there is a problem that a vehicle trying to park may collide with the handcart placed in the parking lot and cause damage to each other.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention has been made to solve the above problems, and an object thereof is to provide a caster device that can prevent a driver of a vehicle trying to park from easily noticing and colliding with a handcart placed in a parking lot.

Means for Solving the Problems

[0005] In order to solve the above problems, the caster device of the present invention is a caster device including a tire portion having a circular outer shape that contacts the ground, a wheel portion having a circular outer shape provided inside the tire portion to support the tire portion, and a shaft portion provided at the center position of the wheel portion to rotatably support the tire portion and the wheel portion, wherein a light storage agent is provided on the wheel portion. In the caster device of the present invention, it is desirable that the wheel portion is formed of a material containing the light storage agent. ​In the caster device of the present invention, it is desirable that a phosphorescent member molded from a material containing the phosphorescent agent is attached to the wheel portion. In the caster device of the present invention, it is desirable that a wheel cover molded from a material containing the phosphorescent agent is detachably provided on the wheel portion. [Effects of the Invention]

[0006] The caster device of this invention comprises 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, and is characterized in that a phosphorescent material is provided on the wheel portion. For example, this has the effect of making it easier for drivers of cars trying to park to notice a handcart placed in a parking lot and preventing collisions, and also prevents collisions or tripping over a handcart placed indoors. Furthermore, the phosphorescent effect is enhanced when the wheel portion has a larger surface area than the tire portion. Furthermore, the design described in claim 2 allows the entire wheel to be illuminated, which has the effect of being easily noticeable. Furthermore, the method described in claim 3 has the effect of allowing the shape of the phosphorescent member to be customized. Furthermore, the design described in claim 4 has the advantage that the wheel cover can be retrofitted and replaced if it is damaged. [Brief explanation of the drawing]

[0008] The embodiments for implementing this invention will be described in detail below with reference to Figures 1 and 2.

[0009] 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.

[0010] 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.

[0011] The tire portion 2 is preferably made of a rubbery material, but may also be made of a synthetic resin material.

[0012] The wheel portion 3 is formed by injection molding from a synthetic resin material made of polypropylene resin.

[0013] 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.

[0014] The phosphorescent material 5 stores light (electromagnetic waves) and emits light even after light exposure stops; strontium aluminate is commonly used. It is usually a milky white color that is nearly colorless.

[0015] The caster device 1 can be used as a caster device 1 for a handcart such as a shopping cart or a silver cart, a carry bag, a trunk, a tricycle, or a toy. In the dark, such as in a room after the lights are turned off or at night, the wheel portion 3 emits light, and the item to which the caster device 1 is attached can be visually recognized.

[0016] FIG. 2 is a front view of the caster device 1 in which the light storage member 8 is attached to the wheel portion. The light storage member 8 is formed of a material containing a light storage material and is attached to the wheel portion 3.
