ABSTRACT:
BACKGROUND OF THE INVENTION
The instant invention is directed to a toy which is adapted to rotate a segmented string which can be formed into various convoluted forms.
Various devices, some of which are toys, are adapted to rotate flexible strips or strings to form convoluted figures. Certain numbers of these devices are illustrated in U.S. Pat. Nos. 1,141,434; 3,107,094; 3,439,446; 3,964,189. None of the cited devices has the capability or the intent to form varying size and configurated convoluted figures as does the toy of the invention.
Accordingly, it is an object of the invention of provide a toy of simple and inexpensive construction.
Another object of the invention is a toy which is capable of forming an indeterminate member of varying shapes and forms of convoluted configurations dependent upon the skill of the user.
Another object of the invention is the provision of a power driven hand held toy.
Another object of the invention is the provision of a toy which finds use with a wide range of ages.
SUMMARY OF THE INVENTION
The invention is directed to a toy which is comprised of a hand held drive having a shaft which rotates about an axis and a crank connected with an end of the shaft and extending radially therefrom. An elongated flexible member is connected at one end with the crank at a location radially spaced from the axis and an anchor member is connected with an opposite end of the elongated flexible member. The anchor member is adapted to control -the position of the elongate flexible member during operation of the toy.
The drive is preferably comprises an electric motor carried in a plastic housing which is in preferably the form of a pistol grip. Controls are provided which actuate, deactivate and vary the RPM's of the electric motor. These controls include an on/off button and a rheostat slide. The housing also carries a battery or batteries which are the power source for the electric motor and may drive it to speeds which may vary between 100 and 10,000 RPM's.
The elongate flexible member preferable comprises a segmented string The elongate member is preferable between 6″ and 36″ in length.
The crank comprises a circular wheel which is mounted along its axis of rotation with the end of the shaft. An end of the elongated flexible member is connected with the wheel adjacent its periphery. The anchor may comprise one of many objects such as a suction cup, a ball or a star burst.
