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.

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.
