Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to toys, and more
particularly, to a simulated pupil assembly capable of changing the
size in a simulated eye using same.
[0003] 2. Description of Related Art
[0004] The size of a person's pupil can dilate or contract
according to the person's emotion. The pupil is dilated when a
person is terrified or astonished. On the other hand, the pupil is
contracted when a person is unpleasable or uninterested.
[0005] Now, various dolls and animated plush type toys as known can
imitate human and/or animal characteristics. In such toys, various
efforts have been made to simulate the eyes of human or animal.
Some dolls only have plastic button eyes. And some simulated eyes
are painted on the face of the dolls. However, the eyes of such
toys are toneless, and can not change the size of the pupils to
express lively expression.
[0006] What is needed, therefore, is a simulated pupil assembly
capable of changing the size in a simulated eye using same to
overcome or at least alleviate the above-described problem.

DETAILED DESCRIPTION
[0015] Embodiments of the present disclosure will now be described
in detail below, with reference to the accompanying drawings.
[0016] Referring to FIGS. 1 and 2, a simulated eye 10, according to
a first exemplary embodiment, is shown. The simulated eye 10
includes a simulated eyeball assembly 100 and an simulated pupil
assembly 200.
[0017] The simulated eyeball assembly 100 is a ball-shaped
configuration. The simulated eyeball assembly 100 defines a
receiving space 110 and a first circular through hole 120. The
simulated eyeball assembly 100 includes an outer surface 130 and an
inner surface 140. The color of the outer surface 130 is white. The
first circular through hole 120 communicates with the receiving
space 110. A fixing structure 141 extends from the inner surface
140 opposite to the first circular through hole 120 toward to a
center of the receiving space 110.
[0018] The simulated pupil assembly 200 is received in the
receiving space 110 facing the first circular through hole 120. The
simulated pupil assembly 200 includes a substrate 210, a number of
blades 220 engaged with the substrate 210, and a driving device 230
engaged with the substrate 210 and the blades 220. In the present
embodiment, the pupil assembly 200 has eighteen blades 220.
[0019] Referring to FIGS. 3 and 4, the substrate 210 includes four
fixing portions 211 and a circular plate 215. The circular plate
215 includes a first surface 215a, a second surface 215b opposite
to the first surface 215a, and a sidewall 215c. The first surface
215a faces the first circular through hole 120. The four fixing
portions 211 extend outwardly from a portion of the circular plate
215 along the radial direction. An angle between adjacent fixing
portions 211 is 90 degrees. The four fixing portions 211 extends
equidistantly around the inner surface 140 on a same plane passing
through the center of the simulated eyeball assembly 100 parallel
the first circular through hole 120, thus forming a front receiving
room 111 and a back receiving room 112 (Seen in FIG. 2). The first
circular through hole 120 communicates with the front receiving
room 111. The fixing structure 141 is received in the back
receiving room 112.
[0020] The circular plate 215 defines an aperture 215d, a number of
rectangular slots 215e, and a number of rotation portions 215f. The
aperture 215d is formed in a center of the circular plate 215. The
number of rectangular slots 215e are aligned equidistantly around
the aperture 215d in the surface adjacent the sidewall 215c of the
circular plate 215. The number of rotation portions 215f are formed
corresponding to the rectangular slots 215e on the cylindrical
surface. A center axis OO' is defined passing through the center of
the center hole 215d. The rotation portion 215f also can be a
sleeve. In the present embodiment, the center axis of each rotation
portion 215f is perpendicularly to the center axis OO'. In the
present embodiment, the simulated pupil assembly 200 has eighteen
rectangular slots 215e and eighteen rotations portions 215f
corresponding to the rectangular slots 215e.
[0021] The blade 220 is an arcuate configuration. The blades 220
can be made from plastic or metal material. In the present
embodiment, the blades 220 are made from ferromagnetic material
such as nickel or iron. Each blade 220 includes a linking end 221,
a distal end 222, and an outside surface 223. The linking end 221
can be a rotating shaft or a sleeve. In the present embodiment, the
linking end 221 is a sleeve. The linking end 221 is rotatably
mounted to the corresponding rotation portion 215f. In the present
embodiment, the color of the outside surface 223 is blue. When the
linking end 221 is rotatably mounted to the corresponding rotation
portion 215f, thereby the eighteen blades 220 are arranged to
sequentially overlap each other to cooperatively form a dome. The
distal ends 222 cooperatively define a second hole 222a. When the
blades 220 rotate about the rotation portions 215f toward or away
from the substrate 210, the diameter of the second hole 222a will
be corresponding contracted or dilated. In the present embodiment,
the second hole 222a is coaxial to the first circular through hole
120.
[0022] Referring to FIGS. 3 and 5, the driving device 230 includes
a motor 231 and a transmission mechanism 232. The motor 231 is
fixed on the fixing structure 141. The motor 231 can be a rotary
motor or a linear motor. In the present embodiment, the motor 231
is a linear motor. The motor 231 includes a motor shaft 231a.
[0023] The transmission mechanism 232 is connected the motor 231 to
the blades 220. The transmission mechanism 232 includes a
transmission shaft 232a, a circular transmission frame 232b, a
center support 232c, and a hinge 232d. The center support 232c lies
on a diameter of the circular transmission frame 232b. The center
support 232c is connected the transmission shaft 232a to the
circular transmission frame 232b. The transmission shaft 232a is
connected to the motor shaft 231a through the hinge 232d. The
circular transmission frame 232b is received in a space formed
between the blades 220 and the substrate 210. In the present
embodiment, the circular transmission frame 232b is magnetic. When
the motor shaft 231a moves along a direction A of the center axis
OO', the blades 220 are driven magnetically to move in the A
direction, as a result the second hole 222a of the simulated pupil
assembly 200 is dilated. Similarly, when the motor shaft 231 a
moves along an inverted direction of the center axis OO', the
blades 220 are driven magnetically to move in the inverted
direction of A direction, as a result the second hole 222a of the
simulated pupil assembly 200 is contracted. The circular
transmission frame 232b can also be a non-magnetic substance. With
the above configuration, the simulated pupil assembly 200 is
capable of changing the size of the second hole 222a. .
[0024] Referring to FIG. 6, an simulated eye 20, according to a
second exemplary embodiment, is shown. The simulated eye 20 of the
second embodiment is similar to the simulated eye 10 of the first
embodiment, except for the structure of the simulated eyeball
assembly 300, the driving device 430, and the substrate 410. Four
cable through holes 413 are defined on the substrate 410. The
driving device 430 includes a motor 431, four cables 432, and a
magnetic spring 433. The magnetic spring 433 is received in a
receiving space formed between the blades 420 and the substrate
410. The magnetic spring 433 includes opposite ends 433a, 433b. The
end 433a attracts the blades 420, and the end 433b is attached to
the substrate 410. The end 432a of the cable 432 is fastened on the
end 433a through the cable through hole 413. The ends 432b of the
four cables 432 are fasten on the motor 431 via a motor shaft 431a
thereof.
[0025] When the motor shaft 431a moves along a direction B of the
center axis OO', the magnetic spring 433 is constricted, the blades
420 are driven magnetically to move in the B direction, as a result
the simulated eye 20 looks have a smaller pupil. Otherwise, when
the motor shaft 431a moves along an inverted direction of the
center axis OO', the blades 420 are driven magnetically to move in
the inverted direction of the B direction, as a result the
simulated eye 20 looks have a larger pupil.
[0026] Referring to FIG. 7, a simulated eye 30, according to a
third exemplary embodiment, is shown. In this embodiment, the
circular transmission frame 632b and the blades 620 is made of
plastic. The simulated eye 30 further includes a number of elastic
elements 500 connected the blades 620 to the substrate 610. A pull
force is applied on the elastic element 500. In the present
embodiment, the elastic elements 500 are elastic bands. The blades
620 are pressed on the circular transmission frame 632b through the
elastic elements 500, and moves together with the circular
transmission frame 632b. When a motor shaft 63 la moves along a C
direction of the center axis OO', the blades 620 are driven
elastically to move in the C direction, as a result the simulated
eye 30 looks have a smaller pupil. Otherwise, when the motor shaft
631a moves along an inverted direction of the center axis OO', the
blades 620 are driven elastically to move in the inverted direction
of the C direction, as a result the simulated eye 30 looks have a
larger pupil.
[0027] While certain embodiments have been described and
exemplified above, various other embodiments will be apparent to
those skilled in the art from the foregoing disclosure. The present
disclosure is not limited to the particular embodiments described
and exemplified, and the embodiments are capable of considerable
variation and modification without departure from the scope of the
appended claims.
