| Abstract | A handy toy for throwing and catching, which includes a substantially
spherical body comprised of a core holder and a big amount of unitary
filaments which have each an elastic, circular rod-like structure and
which uniformly radiate from the core holder; and a rust-proof steel ball
inserted inside the core holder. The filaments and the core holder are
unitarily made of elastic plastic material through injection molding
process to form a soft and elastic spherical body for amusement. |

BACKGROUND OF THE INVENTION
The present invention relates to a handy toy, and more particularly, to the
one which has a substantially spherical configuration made through
injection molding process, and which is formed from a big amount of
floppy, slender filaments that uniformly radiate from a central core.
U.S. Pat. No. 4,756,529 to Stillinger, disclosed an amusement device which
has a substantially spherical configuration, and which is formed from a
large plurality of floppy, elastomeric filaments that radiate in a dense,
bushy manner from a central core region. This amusement device is easy to
throw and catch for amusement. According to Stillinger's disclosure, three
long lengths of extruded rubber filaments are each wound in a pattern of
reverse bend loops, the three stretched loop units are then placed
relative to one another along thee orthogonal axis, and a conventional
cinching device is wound where the wound filament loops centrally cross
one another and drawn tight to gather them. One of the disadvantages with
the Stillinger's amusement device is that the winding process makes the
manufacturing process complicated and time consuming. Another disadvantage
of the said amusement device is that the filaments can not be uniformly
wound to the central core region, i.e. some may densely gathered to the
central core region and some others may loosely gathered thereto. As a
consequence, an attractive outer appearance can not be achieved. This
disadvantage of poor outer appearance will become more apparent a certain
period after use.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a handy toy for
throwing and catching, which is generally made of elastic plastic material
through injection molding process, and in which a big amount of unitary,
floppy, elastic filaments are uniformly secured to a core holder to form
therewith an attractive hedgehog-like body which does not deform easily.
Another object of the present invention is to provide a handy toy for
throwing and catching, in which there is a core holder having a hole in a
diameter of 2 mm which can be stretched to open for the insertion therein
of a steel ball so that the toy will sink when it is placed in water, and
in which the spherical body is formed of a big amount of floppy, slender,
circular rod-like filaments uniformly radiate from a core holder which do
not hurt during throwing/catching amusement game play.
According to a preferred embodiment of the present invention, the handy toy
takes the form of a plurality of floppy, circular rod-like filaments
incorporated with a core holder in such a manner that they radiate
uniformly outwardly from the core holder to form therewith a substantially
spherical object. The filaments and the core holder are unitarily made of
elastic plastic material through injection molding process so as to
satisfactorily avoid the disadvantages encountered in the aforesaid
amusement device which apply binding process to secure filaments to a core
region.
BRIEF DESCRIPTION OF THE DRAWINGS
The drawings disclose an illustrative embodiment of the present invention
which serves to exemplify the various advantages and objects hereof, and
are as follows:
FIG. 1 is a perspective view, illustrating the outer appearance of a handy
toy embodying the present invention; and
FIG. 2 is a sectional elevation of the handy toy of FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 and 2, a handy toy of the present invention is a
throwing/catching device which is easy to catch and has substantially
spherical body (10). The spherical body (10) comprises a steel ball (16)
covered with a core holder (14) and a big amount of floppy, elastic,
slender filaments (12). The filaments (12) and the core holder (14) are
unitarily made of plastic material through injection molding process.
The steel ball (16) is made of lead or nickel-chrome alloy which is
rust-proof and provides high specific gravity and density. Because the
specific gravity of the steel ball (16) is much higher than water, the
steel ball (16) immediately carries the connected core holder (14) as well
as the filaments (12) to sink, like a hedgehog, when the spherical body
(10) is placed in water. Because the high density steel ball (16) is
positioned in the core of the spherical body (10), the spherical body (10)
can be more stably and accurately played in throwing and catching.
The filaments (12) are made of a kind of plastic material commercially
named KRATON-G from American Shell. During production, a solvent is added
to the material of KRATON-G for softening. After the injection molding
process, a big amount of floppy, slender, elastic filaments (12) uniformly
radiate from a core and form a spherical body (10) like a lively hedgehog.
The filaments (12) each have an elastic, soft, fine, circular rod-like
structure convenient for hand grasping. The elastic, soft, fine, circular
rod-like structure provides good shock absorbing effect. At the instant
the spherical body (10) is caught, the filaments (12) absorb much energy
and, unlike the convenient similar throwing/catching devices, do no bounce
or get away from one's grasp easily. Because the filaments and the core
holder are shape molded into a consolidated unit, the filaments do not
break or deform easily and are constantly maintained in right position
uniformly radiating from the core holder.
The core holder (14), described as above, is made of KRATON-G added with a
solvent for softening so as to provide suitable elasticity property after
made with the filaments (12) through injection molding process. The core
holder (14) is disposed in the central part of the spherical body (10) and
the filaments (14) unitarily radially extend outward therefrom. The core
holder (14) has a hollow body comprising a hole (15) in diameter about 2
mm through which the steel ball (16) can be inserted inside the core
holder (14). Because of the high elasticity of its material property, the
hole (15) can be stretched open to a diameter of 20 mm or more so that the
steel ball (16) can be conveniently placed inside the core holder (14).
After stretching force is released from the core holder (14), it draws
together immediately to turn the hole (15) to original size. The
connecting area between the core holder (14) and the filaments (12)
defines to the cross sections of the filaments (12) so that a fine and
attractive outer appearance can be obtained. Because of the high
elasticity of the material property of the KRATON-G, the filaments (12) do
not break or deform during throwing and catching operation.
Having described my invention as related to the embodiment shown in the
accompanying drawings, it is my intention that the invention be not
limited by any of the details of description, unless otherwise specified,
but rather be construed broadly within its spirit and scope as set out in
the appended claim.
