Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The invention relates to pinwheel toys and more particularly to a pinwheel toy presenting an unusual visual display produced by an electronic head with flashing lights which reflect off the pinwheel blades made from holographic film or the like. 
         [0003]    2. Prior Art 
         [0004]    Pinwheel toys are well known in the prior art. They usually consist of one or more shaped pieces of plastic, paper or the like, cut from sheet material to define a plurality of blades with a central orifice through which a pin or shaft is passed when the pinwheel is mounted for rotation on the pin or shaft. The pin or shaft is usually mounted perpendicular to another elongated shaft which is used as a handle. Wind blowing against the blades of the pinwheel causes rotation of the blades about the pin or shaft like a propeller, creating an effect enjoyed particularly by children. 
         [0005]    Attempts are often made by pinwheel makers to create impressive visual displays with the rotation of the pinwheel. For example, U.S. Pat. No. 2,857,507 discloses an electric lawn ornament having multicolored lights behind a pinwheel to produce an impressive visual display while spinning. Some pinwheels are also made to be visually impressive while not rotating such as by having various patterns imprinting on the blades. A prior pinwheel was known and was sold commercially, having lights on “wings” facing the pinwheel. 
         [0006]    Plastic toys of various types containing dyes or pigments, even fluorescent, phosphorescent and dayglow dyes or pigments, are also known. 
       SUMMARY OF THE INVENTION 
       [0007]    It is the object of the present invention to provide an improved pinwheel having an amusing and exciting display both when spinning and when not spinning. 
         [0008]    It is another object of the present invention to provide a pinwheel having blades the appearance of which are accentuated by flashing lights when spinning. 
         [0009]    The above objects are obtained in the present invention by producing the pinwheel blades of a decorative and preferably holographic film and providing an electronic head with flashing lights which can be easily and simply activated to reflect off the front surface of the pinwheel blades to provide a changing display when spinning.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0014]    Referring to  FIGS. 1-3 , a pinwheel toy ( 2 ) according to the present invention is disclosed having a handle ( 6 ), head ( 3 ) with blades ( 4 ) and a pin or shaft ( 8 ) about which the blades ( 4 ) are adapted to rotate. Except for the shape of the blades ( 4 ), the precise construction of the pinwheel ( 2 ) structure is not part of the present invention, and such a pinwheel may take any operative form. 
         [0015]    One important feature of the pinwheel of the present invention is the use of decorative and preferably holographic film to produce the blades ( 4 ) thereby giving the blades ( 4 ) an attractive and preferably three-dimensional appearance typical of holograms. 
         [0016]    Engaged to the end ( 9 ) of shaft ( 8 ) is an electronic module ( 10 ) containing lights, preferable lighted electronic diodes (LEDs), desirably driven by batteries ( 13 ), the module ( 10 ) having a circuit, preferably a circuit board or PCB ( 11 ) and timer chip within the module ( 10 ), all desirably within a cylindrical capsule ( 5 ) coaxial with the shaft ( 8 ). Two on-off buttons may optionally be provided, but preferably the lights are turned on by an impact switch as part of the module ( 10 ) within the capsule ( 5 ), simply by tapping the front end ( 12 ) of the capsule ( 5 ). The timer, part of the circuit, turns the lights off after a predetermined time, e.g. 8-15 seconds. 
         [0017]    At least one, and preferably at least two different LEDs ( 16 ,  18 ) are provided within the capsule ( 5 ) and which face backwards towards blades ( 4 ) and handle ( 6 ). At least two different LEDs ( 16 ,  18 ) are preferred because each LED may be provided to emit a different color, e.g. blue and red, although other different colors may be provided, and more than two LEDs may be provided. The circuit desirably provides that the lights flash alternatively, first one color, then another color, with preferably two colors not flashing at the same time. 
         [0018]    In a preferred embodiment, the LED lights ( 16 , 18 ) are tilted at an angle of about 12° to 20°, preferably 15°, from being parallel to the shaft ( 8 ). Such slight degree of tilt enhances the visual effect of the light reflecting off the blades ( 4 ). In addition, the LED lights are spaced from the pinwheel blades by 0.2 to 1.5 inches, preferably about 0.55 inches, so that the light is projected in a wider circle off the blades ( 4 ), and not just off the central part of the blades. 
         [0019]    As shown in the figures, the capsule ( 5 ) is desirably of a circular-cylindrical configuration. The LEDs ( 16 ,  18 ) are desirably arranged, as noted above, to point in a direction of about 12° to 20° from the shaft ( 9 ). As indicated above, the capsule has a rearwardly facing wall, best shown in  FIG. 3 , through which the light from the LEDs flash. For purposes of simplicity, the entire capsule ( 5 ) is made of a clear or translucent plastic material, although it is only essential that the back face ( 11 ) be sufficiently clear or transparent enough for the LED light to pass therethrough onto the blades ( 4 ) of the pinwheel. 
         [0020]    As best shown in  FIG. 2 , the blades ( 4 ) of the pinwheel ( 2 ) are provided with a front surface, facing the flashing lights of the LEDs, which is relatively flat for about half the total width of the pinwheel. For example, considering the pinwheel as illustrated in  FIG. 2 , the front face ( 41 ), unlike most pinwheels, is relatively flat and does not begin to bend away to the curved area ( 42 ) until each of the blades ( 4 ) has reached approximately two-fifths to three-fifths the distance of each blade from the center at the shaft ( 8 ) to the outer tip of each blade. The purpose in making the blades flatter at the front end or edge ( 41 ) facing toward the LEDs is to provide a greater area of contact of the LED light against the rotating blades ( 4 ) than would be provided by usually shaped pinwheel blades. For example, in one pinwheel example having a width from blade tip to a blade tip at a position 180° from the first blade tip, the width of the flat area ( 41 ) is approximately 3.5 inches. 
         [0021]    When the front face of the capsule ( 5 ) is tapped, e.g. against a surface, the internal impact switch is engaged and the LEDs ( 16 , 18 ) alternatively flash toward the pinwheel blades ( 4 ), on and off, and reflect light, preferably alternatively colored lights, off at least the front surfaces ( 41 ) of the blades ( 4 ) to give an exciting appearance as the holographic film blades spin around the pin or shaft ( 8 ). 
         [0022]    In order to protect the electronic module ( 10 ) and blades ( 4 ) from damage when the pinwheel ( 2 ) is at rest on a surface, a stabilizing element ( 30 ) is integrally engaged to the end ( 32 ) of the shaft ( 8 ) so as to receive the end of handle ( 6 ). The flat edge ( 34 ) of the stabilizing element ( 30 ) acts holds shaft ( 8 ) perpendicular to the surface on which the pinwheel rests to maintain the module ( 10 ) and blades ( 4 ) out of contact with such surface.
