ACCESSARY USING THE SAME

Technical Field

The present invention relates to a photochromic decoration member

which emits various colors by an ultraviolet ray, and in particular to a

photochromic decoration member and its use in which photochromic beads are

filled in a transparent tube and are used as at a decorated object a decoration

member. The life spans of the photochromic beads may be extended, and

decorated objects may be designed to emit various colors.

Background Art

Generally, the color of a photochromic pigment changes due to

ultraviolet ray, and the same recovers its original color based on other

wavelengths such as heat or visible light.

In addition, a photochromic pigment is mixed with a synthetic resin

material based on an inherent characteristic of the photochromic pigment and is

used for a new material development. A photochromic pigment may be coated

or mixed when a raw thread is made. The thusly manufactured fabric material is

used for clothes.

However, since a ultraviolet ray is intensively emitted at an exposed

portion in the case of a photochromic pigment, integrated objects or clothes, the

inherent characteristics of the photochromic pigment cannot be maintained long

time.

Best Mode for Carrying Out the Invention

The photochromic decoration member and the use of the same

according to a preferred embodiment of the present invention will be described

with reference to the accompanying drawings.

If there are not any definitions concerning the technical and science

terms used in the present invention, they should be understood with the

meaning that a person skilled in the art could understand. The same operation

and construction as the conventional art will be omitted.

Figure 1 is a view illustrating a photochromic decoration member having

a circular cross section according to a preferred embodiment of the present

invention.

As shown therein, the photochromic decoration member 1 according to

the present invention is manufactured in such a manner that photochromic

beads 12 formed of micro beads of diameters of less than 0.01mm or football

ball size beads are inputted into a glass or plastic transparent tube 11, and then

the opened transparent both ends of the same are sealed with a stopper 13.

Namely, the photochromic decoration member of the present invention

is designed so that the photochromic beads are freely movable in the

transparent tube like a sand watch and are filled in such a manner that the

photochromic decoration member has a smaller volume than the volume of the

transparent tube. The position of the pigment can be randomly changed based

on the position change of the decorated objects, so that it is possible to prevent

a fast pigment change due to an intensive ultraviolet ray. The above

construction is designed so as to overcome the conventional problem that the

characteristics of the photochromic pigment contained in the decorated object

are not maintained long time since only part of the same is intensively exposed

to the light.

The photochromic beads according to the present invention are

manufactured by coating olefin wax at photochromic pigment powder which

emits various colors by receiving a ultraviolet ray as an energy source.

According to the method for coating olefin wax at the photochromic pigment

powders may be implemented by known various methods based on their sizes,

but in case of micro powders, a spraying and drying method is preferably used.

The transparent plastic tube may be made of any type of a transparent

polymer resin capable of transmitting an ultraviolet ray. Preferably, it is made of

a transparent polymer resin such as polycarbonate, polyethyleneterephthalate,

polyvinylchloride, polystyrene, etc.

The transparent tube according to the present invention may be formed

in a certain shape capable of receiving photochromic beads therein and may be

preferably formed in a conical shape or a rectangular shape, a triangle shape,

etc. when viewing in its cross section direction. In the entire shape of the same,

a certain shape may be obtained while matching with a 3D shape of a

decorated object such as a straight shape, a donut shape, and a star shape.

In the present invention, the photochromic pigment used in the present

invention may emit various colors by receiving an ultraviolet ray. A certain

compound, which does not change its color in reaction with olefin wax, may be

preferably adapted. The photochromic pigment powder may be formed of a

spiropyran compound, spirooxydine compound, naphthopyran compound, etc.

The olefin wax used in the present invention has an excellent durability

rather than other types of waxes and is aliphatic hydrocarbon compound

corresponding to a straight chain or branched monoolefin or polyolefin having at

least one carbon double couple (-C=C-). Preferably, the olefin may include a

substituent such as halogen atom group, oxalic acid group, nitro group, amino

group, cyano group, carbonyl group, acetoxy group, aromatic group, carboxyl

group, mercapto group, etc. The olefin wax according to the present invention

may be preferably formed of aliphatic olefin of 2~10 carbons and may be

preferably formed of a straight chain or branched pentane such as ethylene,

propylene, 1-butene, 2-butene, isobutene, 1-pentene, 2-pentene, 2-methyl-1-

butene, 2-metyl-2-butene; a straight chain or branched chain hexen such s 1-

hexen, 2-hexen, 3-hexen, methyl-pentane; polyolefin such as butadiene,

pentadiene, hexadiene; alicyclicolefin such as cyclopentene,

methylcyclopentene, cyclohexen, methylcyclohexen, cyclooctene,

cyclopentadiene, cyclohexadiene, cyclooctadiene. Preferably, it is formed of at

least one olefin wax selected from the group comprising low level olefins having

2~6 carbons such as ethylene, propylene, n-butene, i-butene and cyclohexen.

Figure 2 is a view illustrating a blinder curtain in which a photochromic

decoration member of the present invention is attached in a straight shape, so

that various colors are emitted as sunlight transmits. The photochromic

decoration member of the present invention may be attached in various shapes

and may be well adapted to conventional woven curtain or blinder curtain. In

particular, in the case of the woven curtain, the photochromic decoration

member is preferably attached to the portions in which the curtain is folded or

unfolded, so that a photochromic effect may be maximized by obtaining a more

active motion of the photochromic decoration member.

Figure 3 is a view illustrating a hair band attached with a photochromic

decoration member having a rectangular cross section according to another

embodiment of the present invention.

Figure 4 is a view illustrating a tennis racket in which a donut shape

photochromic decoration member is attached to a grip according to further

another embodiment of the present invention.

Here, the decoration member may be attached in various methods. It is

preferred that it may be attached to an attaching portion of an attached object

using a binder.

More preferably, it is possible to obtain a splendor visual effect in night

and day time by attaching a noctilucent member at both ends of the

photochromic decoration member, in detail, at a lateral side of the stopper 13.

Industrial Applicability

As described above, in the present invention, it is possible to maintain a

photochromic characteristic of a decorated object for long time period by

providing a photochromic decoration member in which a photochromic pigment

is not fixed at a decorated object.
