     BACKGROUND OF THE INVENTION 
     1. Field of Invention 
     The present invention relates to entertainment devices such as Flying toys. The invention is more particularly related to flying toys that are tethered to a fixed point so as to move in a circular pattern. 
     2. Discussion of Background 
     Toy airplanes that fly around a centrally located pylon have been very popular with children. For the most part, such toy airplanes have included complex mechanical linkages to obtain simulated flying of the toy airplane. In other cases, the propeller was driven and the wings provide the necessary lift to fly the airplane. In some such toy airplane systems, one motor is utilized to rotate the tethered airplane with another motor utilized to control the propeller of the airplane. 
     SUMMARY OF THE INVENTION 
     The present inventors have realized that current propulsion systems for flying toy devices can be improved via the use of an enclosed air propulsion system. The present invention includes the addition of a simulated fan jet type enclosed propulsion system mounted in the body of a flying toy. 
     The enclosed simulated fan jet is a safe propulsion system compared to rotating propellers or other devices known in the prior art. The improvement provides propulsion for the flying toy without exposed moving parts, and provides an element of a “jet age” high tech to the flying toy. In one embodiment, the simulated fan jet propulsion system is the only propulsion of the flying toy. In another embodiment, the simulated fan jet propulsion system is an auxiliary or supplemental propulsion system. 
     The present invention is embodied as a flying toy apparatus, comprising, a toy device having a tether mount receptacle, and an embedded simulated fan jet apparatus configured to propel the toy device. Furthermore, the embedded simulated fan jet may be composed of a simulated turbo fan mounted on bearings, a motor coupled to the simulated turbo fan and configured to rotate the simulated turbo fan, an energy reservoir for supplying fuel to said motor, and the toy itself includes at least one air channel configured to direct air from an output of the simulated turbo fan toward a back end of said toy device. In one embodiment, the energy reservoir is common battery power, and the toy includes a battery holding mechanism configured to hold batteries for powering the embedded simulated fan jet and having positive and negative terminals that are On/OFF switchably connected to corresponding terminals on an electric motor.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring again to the drawings, wherein like reference numerals designate identical or corresponding parts, and more particularly to FIG. 2 thereof, there is illustrated an embodiment of simulated turbo fan powered flying toy  200  according to the present invention. The flying toy  200  is shaped like an airplane, but may be of other shapes or sizes. 
     The flying toy  200  includes an attachment point which may be constructed as an open loop upon which a first end of a tether  220  is attached. The open loop or another attachment mechanism or device may be utilized. A second end of the tether  220  is attached to a hanger or tether anchor  230 . The hanger  230  includes an attachment point that is preferably mounted to a swivel mechanism. 
     An air based propulsion system is embedded in the flying toy  200 . A jet exhaust port  240  provides an exit point for air  250  expelled from the air based propulsion system. An intake port (or air inlet)  260  feeds the air propulsion system. The expelled air  250  provides propulsion to the flying toy. In operation, the expelled air  250  pushes the flying toy  200 , and the attached tether  220  guides the flying toy in a circular path  270 . 
     In one embodiment, the air propulsion system is a simulated jet turbo fan device. FIG. 3 is a sectional view of a simulated jet turbo fan device  300  according to an embodiment of the present invention. As seen in FIG. 3, the simulated jet turbo fan in this embodiment is a hair dryer shaped blower. The simulated jet turbo fan  300  is an impeller driven fan housing having a circular enclosure  310  (that resembles a common hair dryer enclosure) with an exhaust port  320 . Mounting points  330  are used to mount the simulated jet turbo fan inside the flying toy. In one embodiment, the hair dryer shaped blower is miniaturized so as to fit within the toy device and is powered by an electric motor that operates at battery powered level voltages. 
     FIG. 4 is another sectional view of a simulated jet turbo fan housing according to the present invention. A motor mounting area  400  is provided for mounting a motor for powering the simulated jet turbo fan. Mounting posts  410  are used to provide additional attachment points for the fan housing and to provide a fixed distance between a mounting part of the flying toy and the fan housing, providing space for the motor. 
     Preferably, the motor is an electric motor that fits within the motor mounting area  400 . However, other motor types could be utilized, including wind up or rubber band powered motors, gasoline, jet engines, etc. With an electric motor, a power source is needed. As a power source, the flying toy includes a battery holder (not shown) for holding one or more batteries, and wiring that completes a circuit between the batteries and the electric motor. Alternatively, and external power source may be provided with wires running to the flying toy (wires attached and running along side the tether  220 , for example). 
     FIG. 5 is a drawing of views of an impeller  500  and impeller blades ( 510 , for example) used in the simulated jet turbo fan according to an embodiment of the present invention. The impeller is contained inside the circular enclosure  310 . The impeller is driven using the motor in a direct drive arrangement. A shaft receptor  520  is pressure fitted onto a shaft (not shown) of the motor, and the impeller is mounted inside housing  310 . Other arrangements of powering the impeller may be utilized, including belt drive, or geared connections between the motor and impeller, for example. During operation the shaft of the motor rotates causing the impeller to rotate. The rotating impeller blades scoop up air and expel the scooped up air out the exhaust port ( 320 , for example). 
     FIG. 6 is a drawing of an embodiment of an exhaust port  600  of a simulated jet turbo fan according to the present invention. The exhaust port  600  includes an air exit  605  for expelling air driven by the impeller, and mounting holes  610  for securing the exhaust port (and entire simulated jet turbo fan structure) to the flying toy. 
     FIG. 7 is a drawing of a flying toy  200 , including a hidden view perspective of an embedded simulated jet turbo fan  310  according to an embodiment of the present invention. The simulated jet turbo fan  310  along with the electric motor is mounted inside the flying toy  200 . Air intake  260  is coupled to an air transfer channel  700  that feeds an air intake area of the simulated jet turbo fan  310 . The air intake area is an area where the impeller blades scoop up the air from the transfer channel. The impeller then forces the scooped up air out exhaust port  320 . Exhaust port  320  is either directly expels the forced air, or is coupled to an exhaust transfer port  710  which channels the expelled air to the jet exhaust port  240  of the flying toy. 
     Other arrangements for mounting the simulated jet turbo fan  310  and motor may be utilized. For example, the simulated jet turbo fan may be mounted on top of the flying toy (appropriate mounting points would be provided to match mounting holes  330 , for example, or other mounting holes or attachment mechanisms could be implemented). 
     FIG. 8 is a drawing of another embodiment of a flying toy  800  having an embedded simulated jet turbo fan  310  according to the present invention. The simulated jet turbo fan  310  is attached to air intake transfer channel  700  and exhaust transfer channel  710  similar to that shown in FIG.  7 . Air inlet(s)  810  is a scoop mounted to a side of the flying toy for capturing new air to be expelled by the simulated jet turbo fan  310 . In one embodiment, air inlets may be provided on both sides of the flying toy and incoming air is channeled via two corresponding air transfer channels to the air intake area of the simulated jet turbo fan. An advantage of the embodiment in FIG. 8 is a reduced air intake transfer channel length makes for a more efficient transfer of intake air to the simulated jet turbo fan  310 . 
     Although the above described embodiments show the flying plane as an airplane, other flying objects may be used. For example, a helicopter, flying saucer, a pterodactyl or other object shaped similar to an object (animate or inanimate) normally associated with flight. In addition, the present invention is extended to items that are not normally associated with flight. For example, among other items, the present invention includes a “flying” Winnie the Pooh™ bear, a “flying” pig, and a “flying” cow (e.g., Holy Cows™). 
     FIG. 9 is a drawing of another embodiment of a simulated turbo fan powered flying toy according to the present invention. FIG. 9 is a “flying” Cow (Holy Cow™)  900  configured according to the present invention. The simulated jet turbo fan is mounted in an interior of the Holy Cow™  900 , and the exhaust port is directed toward a back end of the Holy Cows™  900 . In one embodiment, the body of the Holy Cow™  900  is shaped in a manner that assists in balanced rotation of the Holy Cow™  900  during operation. Such assistance is found in aerodynamics that may include, for example, a more narrow front end, fin shaped legs, weighted body parts, and/or various placements of the tether attachment  910 , any combination of which helps keep the rotation (or “flight”) of the Holy Cow™ 900 more balanced. 
     FIG. 10 is a detailed view of a hanger/tether anchor according to the present invention. The hanger/tether anchor  230  includes a base part  1000  having mounting holes  1010  that are secured to a ceiling or other mountable surface by inserting and securing attachment screws  1020  through the mounting holes into the mountable surface. Alternatively, glue, bolts, velcro, latches, or other securing mechanisms may be utilized. The base part  1000  includes expansion cuts  1050  to make mounting more secure on expanding/contracting or uneven mounting surfaces. 
     The tether anchor  230  includes an eye attachment  1030  to which the tether  220  is attached. The eye attachment is mounted in a bushing that holds the eye attachment in place and allows it to freely rotate. Free rotation of the eye attachment keeps the tether from being twisted which may cause the tether to wear. In one embodiment, both the tether base and attachment point on the flying toy ( 210 , for example) have a swivel attachments that allow free rotation of the tether  200 . 
     FIG. 11 is a drawing of an embodiment of a simulated turbo fan powered flying toy with flapping wings according to yet another embodiment of the present invention. A flapping wings only flying toy may have insufficient propulsion. Propulsion above and beyond that provided by an ordinary set of flapping wings is needed in order to achieve higher flight altitudes. The simulated jet turbo fan provides the needed additional propulsion. The combination of the simulated jet turbo fan propulsion and the flapping wings makes for an interesting toy to watch in flight. Not only does the toy fly exceptionally well, but the flapping wings add additional appeal for both children and adults. 
     The flying toy  1100  is similar to the Holy Cow™  900  with the addition of flapping wings  1110 . In one embodiment, the wings are constructed of fabric mounted on a plastic (or other material) frame (any set of toy wings could be substituted). In one embodiment, the wings are mounted on an up and down moveable device  1135  that is attached via a crankshaft  1150  and connecting rod  1145  to an electric motor  1155 . In another embodiment, the frame is attached to a pivoting arm connected to a crankshaft type motor shaft. The motor, crankshaft, and pivoting arm cause the wings to flap up and down. The wings provide some propulsion to the flying toy, but are mainly an attractive feature of the toy, while air  1120  expelled by the simulated jet turbo fan provide the main amount of propulsion keeping the flying toy in flight. Aerodynamics of the wings help maintain balanced flight of the flying toy. 
     In one embodiment, the flying toy includes two electric motors, one for powering the flapping wings, and another for powering the simulated jet turbo fan. Both motors may derive energy from a single power supply, or each may have its own power supply (battery pack, for example). In this example, the energy reservoir is the batteries and the fuel is the electrons that flow from the batteries to the electric motor. In another embodiment,sa set of connecting rods or other mechanisms allow both the flapping wings and simulated jet turbo fan  310  to be powered by the same electric motor. The flying toy includes a switch for powering on and off the simulated jet turbo fan and flapping wings electric motor(s). 
     Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
