Abstract
A toy assembly and its associated method of play. The toy assembly includes a hub. Two holes are disposed in the hub through which a loop of string is passed. By winding the string and then pulling the string taut, the string can be caused to rapidly unwind, thus rotating the hub. A removable housing is connected to the hub. The housing has a release mechanism. When the release mechanism is engaged, the housing disengages from the hub. Two players face each other and utilize their toy assemblies to cause their hubs and surrounding housings to turn. The turning housings are then brought to battle by creating contact between the spinning housings. If one housing contacts the release mechanism on another housing, the housing on the contacted toy will separate from the hub and become disabled.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to toy spinning devices that are suspended in the center of a length of string, wherein the toy device rotates as tension is selectively applied to the string.
2. Prior Art Statement
Finger suspended string spinning toys have been in existence for hundreds of years. Traditional finger suspended string spinning toys have a wooden or plastic disk, through which two holes are drilled. A loop of string is passes through the holes in the disk. The ends of the string are looped around fingers on opposite hands. Accordingly, the loop of string suspends the disk between the hands, wherein two sections of the string pass through the disk in between the hands. The disk is then rotated. As the disk is rotated, the looped string winds and contracts. By pulling the hands apart, tension is applied to the wound looped string and the looped string is caused to rapidly unwind. The disk on the looped string acts as a flywheel, wherein its rotational momentum causes the looped string to rewind in the opposite direction after the looped string becomes unwound. The looped string therefore automatically rewinds. By continuously applying tension to the looped string, the disk can be caused to continuously rotate in alternating directions.
Other than changes in material for the disk used in the center of the finger suspended string toy, finger suspended string spinning toys have changed little over time.
In the world of modern toys, old fashioned finger suspended spinning toys have only a limited amount of play value. After only a few minutes of play, a child's fascination in causing the disk to spin wanes and the child loses interest in the toy.
The present invention improves the finger suspended string spinning toy, and utilizes the improved toy in an interactive game. As such, the present invention greatly increases the play value of the toy, and thus its commercial appeal.
SUMMARY OF THE INVENTION
The present invention is a toy assembly and its associated method of play. The toy assembly includes a hub. Two holes are disposed in the hub through which a loop of string is passed. By winding the string and then pulling the string taut, the string can be caused to rapidly unwind, thus rotating the hub. A removable housing is connected to the hub. The housing has a release mechanism. When the release mechanism is engaged, the housing disengages from the hub.
Two players face each other and utilize their toy assemblies to cause their hubs and surrounding housings to turn. The turning housings are then brought to battle by creating contact between the spinning housings. If one housing contacts the release mechanism on another housing, the housing on the contacted toy will separate from the hub and become disabled.
BRIEF DESCRIPTION OF THE DRAWINGS
For a better understanding of the present invention, reference is made to the following description of exemplary embodiments thereof, considered in conjunction with the accompanying drawings, in which:
FIG. 1
is a perspective view of an exemplary embodiment of the present invention with a closed housing;
FIG. 2
is a perspective view of the embodiment of
FIG. 1
with an open housing;
FIG. 3
, is a perspective view of two examples of the present invention, illustrating a method of play; and
FIG. 4
is a side view of an alternate embodiment of the present invention.
DETAILED DESCRIPTION OF THE DRAWINGS
Referring to
FIG. 1
, an exemplary embodiment of the present invention finger suspended spinning string toy
10
is shown. In this embodiment, there is a circular disk assembly
12
. Two holes
14
are eccentrically disposed through the disk assembly
12
. A loop of string
16
passes through the two holes
14
. Rings
18
are connected to the hooped string
16
. The rings
18
are placed on fingers of opposite hands, when the toy
10
is used. As the disk assembly
12
rotates, it winds the loop of string
16
, thereby shortening the effective length of the loop of string
16
between the two rings
18
. By pulling the rings
18
apart with the hands, tension is applied to the loop of string
16
and the loop of string
16
is caused to rapidly unwind. Once the loop of string
16
is unwound, the disk assembly
12
still spins. Thus, the momentum of the spinning disk assembly
12
causes the just unwound loop of string
16
to rewind in the opposite direction. By periodically applying tension to the loop of string
16
by separating the rings
18
, the disk assembly
12
is caused to repeatedly rotate in one direction and then another.
The disc assembly
12
of the present invention differs from traditional prior art disks in a few ways. From
FIG. 1
, it can be seen that arms
20
extend from the peripheral edge of the disk assembly
12
. The arms
20
are connected at one end to the housing
22
of the disk assembly
12
with pivot joints. Each arm
20
is biased into the housing
22
by a small torsion spring (not shown). As the disk assembly
12
spins, centrifugal force causes the arms
20
to extend against the bias of the internal springs. As such, once the disk assembly
12
spins at a predetermined rate of revolution, the arms
20
will fully extend out from the disk assembly
12
. As the disk assembly
12
slows, the arms
20
automatically retract.
In the side faces of the disk assembly
12
are located a series of receiving bores
24
. The receiving bores
24
are symmetrically disposed around the geometric center of the disk assembly
12
. Weight attachments
26
are provided. The weight attachments
26
have stems that pass into the receiving bores
24
with an interference fit. Accordingly, inserting the weight attachments
26
to the receiving bores
24
, the weight of the disk assembly
12
is increased, as is its rotational momentum when it spins.
Referring now to
FIG. 2
, it can be seen that the disk assembly
12
is an assembly of component parts. The disk assembly
12
is comprised of a central hub
30
. The holes
14
for the loop of string
16
are disposed through the hub
30
. The central hub
30
is surrounded by an annular housing
22
. The hub
30
and the annular housing
22
are keyed so that when the annular housing
22
surrounds the hub
30
, the annular housing
22
mechanically engages the hub
30
and prevents either the annular housing
22
or the hub
30
from rotating independently.
The annular housing
22
is a subassembly of two semi-annular sections of housing
32
,
34
. The two semi-annular housing sections
32
,
34
are joined together at one side with a pivot connection
35
. The opposite ends of the semi-annular housing sections
32
,
34
are joined together with a release mechanism that includes a locking finger
36
. A safety guide
39
is also provided to prevent the two semi-annular housing sections
32
,
34
from separating more than a short predetermined distance.
The locking finger
36
is controlled by a push lever
38
that terminates on the peripheral edge of the one of the semi-annular housing sections
32
,
34
.
The semi-annular housing sections
32
,
34
snap closed forming the annular housing
22
. It is only when the push lever
38
is depressed that the annular housing
22
separates and the two semi-annular housing sections
32
,
34
are able to pivot part. It is when the two semi-annular housing sections
32
,
34
pivot apart that the annular housing
22
is free to separate from the central hub
30
. When the two semi-annular housing sections
32
,
34
are in a closed condition, the semi-annular housing sections
32
,
34
form a symmetrical central opening that can retain the hub
30
. However, when the semi-annular housing sections
32
,
34
are in an open condition, they define a non-symmetrical central opening that permits the hub
30
to disengage.
To utilize the present invention, the semi-annular sections of the housing
32
,
34
are opened and the hub
30
is placed into their center. The hub
30
is oriented so that key projections
42
on the hub
30
align with key depressions
44
on the inside surface of the two semi-annular sections of housing
32
,
34
. Once properly positioned, the two semi-annular sections of housing
32
,
34
are closed around the hub
30
, thereby mechanically engaging the hub
30
. The hub
30
is therefore surrounded by the annular housing
22
, creating the complete center disk assembly
12
, as is shown in FIG.
1
.
Returning to
FIG. 1
, it can be seen that the loop of string
16
passes through the holes
14
in the hub. The rings
18
at the ends of the loop of string
16
are held in opposite hands. The disk assembly
12
is rotated slightly, thereby winding the loop of string
16
. This contracts the loop of string
16
. By momentarily pulling the rings
18
at the ends of the loop of string
16
away from each other, the loop of string
16
is caused to rapidly unwind. The unwinding loop of string
16
causes the disk assembly
12
to turn rapidly. The rotational momentum of the disk assembly
12
causes the disk assembly
12
to still spin after the loop of string
16
has unwound. This winds the loop of string
16
in the opposite direction. The rings
18
on the loop of string
16
can again be pulled and the cycle repeats.
As the disk assembly
12
spins, the centrifugal force caused by the rotation of the disk assembly
12
causes the arms
20
to extend from the disk assembly
12
. The arms
20
reach their maximum extension when the disk assembly
12
rotates above at least 50% of its maximum rotational speed. The arms
20
are used in a unique method of play. Referring to
FIG. 3
, it can be seen that to play the game, two players are provided with different finger suspended spinning string toys
10
. Each player makes the disk assembly
12
on his/her toy spin by periodically pulling the rings
18
. As the disk assemblies
12
spin, the arms
20
on the disk assemblies
12
extend. The two rotating disk assemblies
12
are then brought into contact with each other. If the arm
20
on one disk assembly
12
were to strike the release push lever
38
on the other disk assembly
12
, the annular housing
22
on the struck toy would open and the annular housing
22
would separate from the hub
30
, thereby disabling the toy. Two players, therefore, cause their spinning disk assemblies
12
to battle until one of the disk assemblies
12
is disabled.
The safety guide
39
(
FIG. 2
) between the semi-annular sections of housing
32
,
34
prevents the annular housing
22
from flying off the loop of string
16
once it has been opened in a battle. Accordingly, pieces do not fly away from the toy that might cause harm.
Another safety system may also be present to limit the rotational speed of the disk assemblies as they spin. Referring to
FIG. 4
, an embodiment of the present invention finger suspended spinning string toy
10
is shown where flexible tubes
40
are placed around the loop of string
16
between the disk assembly
12
and the rings
18
. The flexible tubes
40
have an internal diameter that is slightly larger than the combined thickness of the loop of string
16
. As such, the loop of string
16
can wind, but the loop of string
16
is prevented from knotting up if it is over-wound. Since the flexible tubes
40
prevent the loop of string
16
from being over-wound, the flexible tubes
40
limit the amount of potential energy that can be stored in the wound loop of string
16
. This, in turn, limits the amount of energy in the loop of string
16
that can be converted to rotational energy, thereby limiting the rotating speed of the disk assembly
12
. By limiting the rotating speed of the disk assembly
12
, it can be ensured that the plastic construction of the disk assembly
12
will not encounter forces in a battle that may cause pieces to break away and cause harm.
