1. Field of the Invention
The present invention relates to artificial flowers, and more particularly to an open/closing apparatus of petals of artificial flowers.
2. Background of the Invention
A natural flower has a short life, such that artificial flowers made of plastic or the like are widely used in offices for ornamental purposes. In most cases, the artificial flowers are made with petals being unfolded.
However, the artificial flowers thus produced do not give a lively feeling, thereby not providing a pleasant feeling to their watchers.
SUMMARY OF THE INVENTION
The present invention is disclosed to solve the afore-mentioned problem and it is an object of the present invention to provide an open/closing apparatus of petals of artificial flowers adapted to open and close petals of the artificial flowers as occasion demands to give a liveliness thereto.
It is another object of the present invention to provide an opening/closing apparatus of petals of artificial flowers adapted to obtain a maximum ornamental effect at a reasonal price.
In accordance with one object of the present invention, there is provided an opening/closing apparatus of petals of artificial flowers, the opening/closing apparatus of petals of artificial flowers comprising:
an expansion member internally disposed underneath a body to expand during absorption of liquid or to shrink during evaporation of the liquid;
a medium member disposed above the expansion member to upwardly move according to expanding force of the expansion member;
a restoring member coupled to an upper side of the medium member to downwardly move the medium member according to resilience; and
a plurality of petal members respectively hinged to periphery of the body, each at a predetermined height to unfold outwardly when the medium member descends or to fold inwardly when the medium member ascends.
In accordance with another object of the present invention, there is provided an opening/closing apparatus of petals of artificial flowers, the opening/closing apparatus of petals of artificial flowers comprising:
an expansion member disposed above a body to expand when liquid is absorbed or to shrink when the liquid is evaporated;
a flexible member coupled to an upper side of the body to flexibly move vertically according to expansion or shrinkage of the expansion member; and
a plurality of petal members respectively attached to center and peripheral sides of the flexible member, each distanced at a predetermined space relative to the upper side of the flexible member to outwardly unfold when the upper side of the flexible member is convexly and upwardly elongated or to inwardly fold when the upper side of the flexible member is concavely and downwardly shrunk.
