SIMULATIVE EYE FOR TOY
Abstract
A simulative eye is capable of being operated between a normal
state and a dilated state. The simulative eye includes an eyeball,
a pupil disposed on the eyeball, an iris surrounding the pupil, and
a light source. When the simulative eye is in a normal state, a
color of the iris is different from that of the pupil when the iris
is not irradiated by the light emitted from the light source. When
the iris is irradiated by the light emitted from the light source,
the color of the iris is almost the same as that of the pupil. As a
result, the simulative eye is changed from the normal state to the
dilated state.

change the simulative eye from the dilated state to the normal
state.
13. The simulative eye as described in claim 12, wherein an
intensity of the second light beam is gradually increased.
Description
BACKGROUND
[0001] 1. Technical Field
[0002] The disclosure relates to toys, and, more particularly, to a
simulative eye for a toy.
[0003] 2. Description of Related Art
[0004] As the development of the electronic technology, more and
more robot toys simulate people's actions, such as, walking,
jumping, and so on. As known, eyes are one of the most important
organs of human body, and people can express various feelings via
the action of the eyes. The eyes of robot toys simulate human eyes
by setting the simulative eyes with the same shape as the human
eyes. However, some of these simulations are restricted to the
eyelids opening and closing and accordingly, other simulation
effect of the eyes of the robot toys are needed to make the robot
looks more lifelike. Therefore, what is needed is a simulative eye
capable of simulating human eyes' actions.

throughout several views.
[0006] FIG. 1 is a perspective view of a simulative eye in
accordance with one embodiment.
[0007] FIG. 2 is a disassembled view of the simulative eye of FIG.

[0008] FIG. 3 is a perspective view illuminating the pupil of the
simulative eye of FIG. 1 in a dilated state.
DETAILED DESCRIPTION
[0009] Referring to FIG. 1, a simulative eye 10 includes an eyeball
100 and a spherical shell 200. An opening 202 is defined in the
shell 200. The eyeball 100, received in the shell 200, includes a
circular pupil 102 and an annular iris 104 surrounding the pupil
102. The pupil 102 and the iris 104, exposed at the opening 202 of
the shell 200, are disposed or formed on the eyeball 100 via
in-mold-decoration (IMD). In the embodiment, the pupil 102 is made
of polycarbonate material, and the polycarbonate is black and
translucent. The iris 104 is made of acrylonitrile butadiene
styrene (ABS) material, and the ABS material is blue and
translucent.
[0010] Referring to FIG. 2, the simulative eye 100 further includes
a general semi-spherical shielding member 300, a circular
supporting plate 400, and a light source 500 mounted on the
supporting plate 400. The light source 500 faces the eyeball, and
emits light having a specific color. In the embodiment, the light
source 500 is a light emitting diode (LED) emitting red light.
[0011] A round hole 302 is defined in the shielding member 300. The
shielding member 300 is made of opaque material, for example,
metal. The position of the hole 302 is corresponding to that of the
pupil 102 and the iris 104 in the eyeball 100, and the diameter of
the hole 302 is larger than that of the pupil 102. In this
embodiment, the diameter of the hole 302 is equal to a sum of the
diameter of the pupil 102 and iris 104. The shell 200 includes a
front cover 201 and a rear cover 203 assembled together by known
mechanisms such as hooks or latches for receiving the eyeball 100,
the shielding member 300, the supporting plate 400, and the light
source 500.
[0012] Referring to FIGS. 1 and 3, when the light source 500 is
turned off, the color of the pupil 102 is different from that of
the iris 104. In this embodiment, the color of the pupil 102 is
black, and the color of the iris 104 is blue. In this condition,
the simulative eye 10 is at a normal state.
[0013] When turned on, the light source 500 emits red light, the
red light passes through the hole 302 and irradiates the blue iris
104. Accordingly, the iris 104 almost has the same color as that of
the pupil 102, that is, the black area of the pupil 102 is dilated.
As a result, the pupil 102 of the simulative eye 10 looks dilated.
In this condition, the simulative eye 10 is said to be in a dilated
state. The simulative eye 10 can be changed from the dilated state
to the normal state by turning off the light source 500.
[0014] When the light source 500 is turned off, the iris 104 resort
back to its original appearance and appears to be blue again, and
the pupil 102 looks contracted. Thus, by turning on and off the
light, the pupil 102 seems to be dilating and contracting. In other
embodiment, instead of being turned off, the light source 10 may
emit light with other colors, such as yellow and/or green. Because
the black area decreases, the pupil 102 also looks contracted.
Further in other embodiment, the light source 10 may be operated to
emit light with changeable intensity, such that the simulative eye
10 may be changed from the normal state to the dilated state or
from the dilated state to the normal state gradually. Therefore,
the simulative eye 10 simulate the dilated and normal state of the
pupil 102 by changing the color of the area of the iris 104 to be
the same as that of the pupil 102 or not.
[0015] Although the present disclosure has been specifically
described on the basis of the embodiments thereof, the disclosure
is not to be construed as being limited thereto. Various changes or
modifications may be made to the embodiments without departing from
the scope and spirit of the disclosure.
