Flying toy
A novel flying toy comprising a ringed or banded rotor launched by a pulled string. The rotor has an outer ring or band and an inner circular disk connected by a plurality of curved blades. The rotor rests upon a spindle set in one end of a handle grasped by the user. The rotor is loosely held by pins in the spindle. A string is wound around the spindle and pulled by the user. The spindle and rotor are spun rapidly causing the rotor to lift off the pins and into the air. The outer band contains air near the blades, and coupled with the configuration of the blades, contributes greatly to aerodynamic lift and flight stability.
The present invention relates to toys; more specifically it is a new and improved flying toy having spinning, band-enclosed propeller blades that are launched from a handle by action of a wrapped and pulled string to impart a rotary motion to the band-enclosed blades.
BACKGROUNDAerodynamic toys is known in the prior art. Many aerodynamic toys consist basically of familiar, expected and obvious structural configurations. Of particular interest, as an example of prior art, is the art disclosed in U.S. Pat. No. 6,146,231, entitled Flying Toy. In the patent, the inventor discloses a flying toy including a handle portion having an upper end. A spindle is mounted top the upper end and has a bore extending downwardly. A rotating rod extends through the bore and into the upper end of the handle to allow relative rotation of the spindle upon the handle. The spindle has a pair of pins extending upwardly. A propeller portion is coupled with respect to the circular platform of the handle portion. The propeller portion includes an inner circular disk. The inner circular disk has a plurality of radially-extending blades integrally formed with a peripheral edge. Each of the blades has a predetermined angle of orientation. A length of string is secured to the spindle. The length of string has an end fixedly secured to the spindle with a remainder of the string being wrapped around the rotating rod just prior to operation of the toy. Operation involves pulling the string while holding the handle still, to rotate the spindle and cause the propeller portion to rotate and lift upward, free of the spindle.
While this toy is an improvement over its prior art, and provides entertainment to children it has certain defects. Among these are instabilities of its direction of flight, and its distance and height of travel.
Therefore, in view of the foregoing a novel improvement in the design and structure of this toy is in order.
SUMMARYTo achieve such an improvement, the improved flying toy comprises a flying rotor comprising a round flat disk and an outer band surrounding and concentric with the disk. The band and the disk are connected by a plurality of curved blades configured to produce aerodynamic lift when the blades are spinning. The disk has a shaft in its center extending downward vertically, and two holes near its center, wherein the holes are on opposing sides of, and equidistant from, the center point of the disk. The toy further has a cylindrical handle with a spindle mounted at one end of the handle. The spindle is confined to rotate while mounted on the handle, wherein the spindle rotation is facilitated. The spindle is made with two pins that extend vertically upward, wherein the pins are made to be received by the two holes made in the disk when the rotor is set atop the spindle. The toy further includes a string, cord or the like, the string or cord wound around the spindle. When the wound string is pulled vigorously the rotor is made to rotate rapidly and flying upward.
OBJECTSThe flying toy has been tested and shown to realize several objectives having benefit to the person using the toy. Among these objects is the flying rotor is far more stable and flies predictably.
A second object is a flying toy that has greater aerodynamic efficiency and therefore, will fly further and higher.
The benefits and advantages of the invention will appear from the disclosure to follow. In the disclosure reference is made to the accompanying drawings, which form a part hereof and in which is shown by way of illustration a specific embodiment in which the invention may be practiced. This embodiment will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made in details of the embodiments without departing from the scope of the invention.
The included Figures show a manually operated flying toy comprising a rotor that is launched from a handle having a spindle, wherein rotational motion is imparted to the spindle and then to the rotor by a a length of string or cord that is wrapped around the spindle and pulled vigorously. One improvement of this invention over prior art flying toys comprises the inclusion of a ring or band encircling blades, wherein the ring traps air and improves lift and stability of flight.

Again with reference to
The blades 1130 are configured to impart lift to the rotor 1100 when the rotor 1100 is spinning. An essential part of the design and novelty of the toy is the inclusion of the outer band 1100, which traps air within, and therefore, in conjunction with the configuration of the blades 1130 imparts more lift to the rotor 1100. By configuration of the blades 1130, it is meant the curvature, width, thickness, and placement of the blades 1130.
