Magnetic Top Toy
Abstract
A wheel-shaped top with magnetic spindles projecting from the
body. A circular disk with a beaded rim is mounted on each end of a
shaft; the rims of the disks forming a two-rail track encircling
the shaft. A handle has two legs attached to opposite ends of the
shaft. The spindles are magnetically attached to the two-rail
track. The top orbits around the track in response to hand
manipulation of the handle; the top is launched from the track when
the orbital speed is sufficient to centrifugally separate the
spindles from the track to spin on a surface, and the top can be
magnetically retrieved, while spinning, by engagement of the
spindles with the shaft or with one or both of the disks. In an
alternate embodiment, the top includes a simulating feature, such
as a continuous or blinking light, a sound, or the like configured
to activate when the top is rotated.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority from and the benefit of
co-pending application Ser. No. 29/206,018, filed May 24, 2004, the
entirety of which is incorporated by reference herein, and
co-pending application Ser. No. 11/086,499, filed Mar. 22, 2005,
entitled MAGNETIC TOP TOY, as a continuation-in-part thereof, which
is incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates generally to toys of the type that
include the combination of a top having a wheel-shaped body with
magnetic spindles projecting in opposite directions along the axis
of rotation of the body, and an apparatus that can be manipulated
to cause the top to spin with the help of gravity, to travel in a
particular path dictated by rails, or the like. In some cases, the
spinning top may be made to separate from the apparatus to spin on
a floor or other flat surface.
[0004] 2. Description of the Prior Art
[0005] The prior art discloses top toys that includes combinations
of tops having wheel-shaped bodies with wire rails, a spiral track,
and the like. Included among the known prior art patents are tops
having a wheel-shaped body with a pair of magnetic spindles
projecting from opposite sides of the body at its axis of rotation
for securing the top to a pair of rails by magnetic attraction.
See, for example, Chen (U.S. Pat. No. 4,031,660, issued Jun. 28,
1977) and Chesler (U.S. Pat. D436,383, issued Jan. 16, 2001), which
also disclose a top with a wheel-shaped body.
SUMMARY OF THE INVENTION
[0006] The toy of the present invention includes a top having a
wheel-shaped body, an axle mounted in the center of the body with a
magnetic spindle at each end projecting from opposite sides of the
body, a track component with a pair of spaced disks mounted on a
shaft so that the rims of the disks function as an endless,
circular, two-rail track enclosing the shaft, and a handle having a
pair of legs that straddle the disks and are attached to a
respective end of the shaft. The top is attached to the two-rail
track by magnetic attraction of the spindles with the rims of the
disks. The top orbits the shaft in response to manipulation of the
handle. If the speed of the top is sufficient to develop a
centrifugal force on the top sufficient to overcome the magnetic
attraction of the top to the disks, it separates from the track to
spin on a floor or other flat surface. The operator can then
retrieve the spinning top by magnetic attraction of a spindle with
an end of the shaft, one of the disks, or the two-rail track. In an
alternate embodiment, the top includes a simulating feature, such
as a continuous or blinking light, a sound, or the like configured
to activate when the top is rotating.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] The present invention is not limited to the particular
details of the device depicted and other modifications and
applications may be contemplated. Further changes may be made in
the above-described device without departing from the true spirit
of the scope of the disclosure herein involved. It is intended,
therefore, that the subject matter of the above depictions should
be interpreted as illustrative, not in a limiting sense.
[0022] FIGS. 1-3 show the assembled toy 10, which includes a top
16, a track component 14, and a handle 12. FIGS. 1 and 3 show the
top 16 with a wheel-shaped body 19 and a pair of magnetic spindles
17 projecting from opposite sides of the body 19 at a rotary axis
common to the body 19 and the spindles 17 as shown in FIGS. 1, 3,
and 4.
[0023] The track component 14 shown in FIGS. 1 and 2 includes a
shaft 32 with reduced-diameter ends 34 and two disks 26 each
mounted on each of the reduced ends 34 where each disk 26 includes
a concave body with an opening 30 at its center for receiving one
of the reduced ends 34 of shaft 32. A beaded rim 28 is formed at
the periphery of each of the disks 26. The disks 26 are mounted on
the opposite ends of shaft 32 in mirror-image relationship such
that the opposed pair of rims 28 form a two-rail track enclosing
shaft 32. In the illustrated embodiment, the rims 28 are circular
and concentric with the axis of shaft 32; hence, when the spindles
17 are magnetically connected to the disks 26, the top 16 travels
in an endless, circular orbit around the axis of shaft 32 as it
travels around the two-rail track defined by the spaced rims
28.
[0024] The handle 12 is comprised of a wire member bent at the
center to form a curved, U-shaped bight 22 defining the free end of
the handle 12. A pair of legs 18 project from the bight 22 and
terminate at spaced free ends 13 as shown in FIG. 2. The end caps
36 include a first hole (not shown) at the internal end of each end
cap 36 to interlock with the reduced-diameter end portion 34 of
shaft 32 inserted through the opening 30 and a second hole (not
shown) that extends diametrically through the cylindrical wall of
each end cap 36 to receive one of the two free ends 13 of the
handle 13.
[0025] A circular clamp 20 is mounted on both legs 18 of the wire
handle 12 at a location near the bight 22. The clamp 20 is formed
by a pair of circular, rimmed disks 21 and 23 having cylindrical
rims 25 and 27 that project from the peripheries of disks 23 and
21, respectively. The rims 25 and 27 have matched sets of notches
aligned to receive legs 18. Rims 25 and 27 are sized to allow one
to fit into the other with a force fit. Each notch of rim 25 is
matched with a notch of rim 27 so as to receive a respective one of
the pair of legs 18 as illustrated in FIG. 1. The clamp 20 is used
as a gripping member for hand manipulation of the toy as
illustrated in FIG. 1.
[0026] In one preferred embodiment of the top 16 shown as FIGS. 3
and 4, the top 16 has a wheel-shaped body 19 and a pair of magnetic
spindles 17 projecting from opposite ends of the axle formed by the
axle halves 42 as shown in the exploded view of FIG. 4. The
spindles 17 are magnetized by contact with a permanent magnet 40
shown in a cylindrical shape, located between the flat ends of
spindles 17. While the use of a single magnet 40 placed between
spindles 17 to impart upon the spindles 17 magnetic attraction,
what is also contemplated is the use of magnetized spindles without
the need of a permanent magnet 40. When the parts of the top 16
shown as FIG. 4 are assembled, the flat ends of the spindles 17 are
seated against a respective flat end of magnet 40. When assembled,
the pointed ends of spindles 17 project from a respective axle half
42.
[0027] FIGS. 5-8 shown how the assembled top toy 10 can be operated
with the hand of a user. The top 16 of the magnetic top toy 10 is
secured as shown in FIG. 5 to the upper external radius of the rims
25, 27. By angling the handle 12, the center of gravity of the top
16 is then moved away from the shaft 32, creating a momentum force
on the top 16 attached to the rim 25, 27. The top 16 then rotates
as it moves along the rim 25, 27 around the track component 14
shown in the shape of disks 26. What is shown is the use of hand
motions, coupled with handle movements, to increase or decrease the
rotation speed of the top 16 along the track component 14. As the
top 16 rotates around the track component 14, it is held in
position by the magnetic forces created by the magnet 40 on the
spindle 17 when in contact with disks 26 made capable of
magnetization.
[0028] FIG. 6 shows how the top 16 can be made to separate from the
track component 14 by either a movement of the handle 12, a
centrifugal force induced by the rotating top 16 along the disks
26, or any combination thereof. FIG. 7 illustrates the case where
the end caps 36 are also made of material capable of magnetization.
In the contemplated embodiment, the top 16 can be held at the
position on the end caps 36 while it maintains its rotation. FIG. 8
shows how the top 16 can be made to rotate on a single disk 26.
While FIGS. 5-8 illustrate how the top 16 can be used on the
magnetic top toy 10 by users, what is disclosed and contemplated is
the capacity of users to operate the magnetic top toy 10 in other
fashions not described or in conjunction with magnetized, metallic,
or other surfaces or elements to enhance the entertainment value of
the magnetic top toy 10. By way of nonlimiting example, users with
great dexterity can place two tops 16 on a single toy 10 and create
new operating modes contemplated but not shown.
[0029] FIG. 9 is a partly tilted elevation view of the top 16 of
the magnetic top toy 10 according to another embodiment of the
present disclosure. In this alternate embodiment, the top toy 10
includes a wheel-shaped top 16 having a body with a pair of
magnetic spindles 17 and a track component 12 made of a material
capable of magnetic engagement for supporting the magnetic spindles
17 of the wheel-shaped top 16. The track component 12 includes a
shaft 32 with a first and a second end 34, and a pair of disks 36
mounted on opposite ends 34 of the shaft 32. The body as shown in
the alternate embodiment includes a peripheral edge 51 for holding
an upper body 44 and a lower body 46. In one preferred embodiment,
the upper and lower bodies 44, 46 are made of transparent or
semitransparent material, such as glass, plastic, or the like.
[0030] As shown in FIGS. 11-12, the body also includes at least an
electrically activated first stimulating feature, which is shown in
FIG. 12 as a colored LED. The LED is connected to an electrical
circuit placed on a circuit board 52 as shown in FIG. 10. The board
52 also holds a centrifugally activated contact 55 as shown in FIG.
12. As the top 16 rotates, a small metallic contact 59 made of a
biasing element 58 such as a spring 58 or a bent and flexible piece
of conductive metal moves to the external radius of the top 16
under the action of the centrifugal force. When enabled by rotation
of the top 16, the contact 55 connects the first stimulating
feature, such as the LED 54 or any other colored light. FIG. 11
shows how small, flat batteries can be used as an energy source
connected to the electrical circuit. In an alternate embodiment,
the first stimulating feature is a sound created by a small speaker
or noise-producing device. While noise- and light-based systems are
described, what is contemplated is the use of any stimulating
feature that may be used for entertainment purposes and associated
with a toy. By way of nonlimiting example, it may be useful to add
sprays and small volumes of water inside the top 16 in an effort to
randomly wet users of the toy 10.
[0031] In another embodiment, the body further includes a control
board 52 with a microprocessor (not shown) for controlling a degree
of simulation of the first simulating feature, such as creating
music or variable noises associated with the top 16. Lights can be
made to flash, blink, either randomly, semirandomly, or when used
in tandem with a game where each top 16 is given specific tasks.
FIG. 13 shows how one or a plurality of batteries 60 can be used
with the LED 54 or other simulating feature shown by a rectangle
either directly with the centrifugally activated contact 55 in a
closed loop shown in the right of the figure. Once centrifugal
force is placed upon the contact 55 by a spinning top 16, the
contact 55 closes and electricity flows on the right circuit
enabling the simulating feature 54.
[0032] What is also contemplated is the use of a body further
including an open-loop electrical circuit shown in the left circuit
of FIG. 13 formed by the magnetic spindles 17 illustrated by black
rectangle connectors. In the open loop, the different elements of
the toy 10 can be used in conjunction with calibrated resistances
R.sub.1 to R.sub.4 to reduce current and enable either a second
stimulating feature located within the open loop or the first
simulating feature at a different degree of stimuli. The top 16
includes two spindles 17 each shown with a resistance R.sub.1 and
alternatively a magnet 40 with a resistance R.sub.2. The current
can be made to pass within these elements and return to the
negative charge of the battery 60 if the top 16 is placed on the
handle 12 consisting of a first conductive element such as the
handle 12 with a resistance R.sub.3 and disks 26 with a resistance
R.sub.4.
[0033] In one embodiment, the light used for the first and second
simulating features is a single light having two different
intensities. In another embodiment, the second stimulating feature
is a sound.
[0034] While specific embodiments of the invention are illustrated
in the drawings and described in the specification, the invention
is not limited to the exact construction shown and described.
Variations in the construction and arrangement of parts and
components are possible without departing from the scope of the
invention as defined in the claims.
