Abstract
An arrangement for attaching an object to a fan blade so that the orientation of the object can be adjusted to achieve a desired orientation while the fan blade is rotated by the fan. The object is attached to the bottom end of an invisible filament. The top end of the invisible filament is attached to an enlargement, such as a button. The button is captured between the fan blade and an elastic band that encircles the fan blade. The button can be manually rotated to thereby rotate the invisible filament and the object so that the object is oriented in the desired manner when rotated by the fan. The object can be of the type that flies with a natural orientation, such as a bird, airplane, space ship, etc.

DETAILED DESCRIPTION OF THE INVENTION
(7) With reference to
(8) In accordance with the principles and concepts of the invention, one or more of the fan blades 16 can have attached thereto an object, such as a flying bat 18 which has a natural orientation during flight. In the example, the fan blades 16 are rotating clockwise in the direction of the arrow 20 when viewed from under the fan 10. Of course, many other objects can be attached to the fan blade 16 which have natural flying orientations, such as airplanes, space ships, flying saucers, etc. In addition, it is not necessary to the operation of the invention that the object 18 has a natural flying orientation, but that the object has a certain orientation that is desired by the user of the fan 10.
(9) In the illustration of
(10) The arrangement for suspending an object 18 from a fan blade 16 in a desired orientation includes an elastic band 22 that encircles the blade 16 and fits tightly thereto. An elastic band 22 is preferred as it can fit around many shapes of fan blades 16. According to this embodiment, a line or tether 24 is connected at a top end thereof to the elastic band 22 in a manner to be described below, and is connected at a bottom end thereof to the object 18. The tether 24 is preferably constructed of a material that does not easily twist or rotate around an axial axis (vertical as illustrated) of the tether 24. In a preferred embodiment, the tether is constructed of a transparent fishing line or filament having a diameter of about 0.4 mm. Other line thicknesses can be employed with equal effectiveness. The transparency of the tether 24 allows the object 18 to appear as flying without any connection to other equipment.
(11) With reference now to
(12) A transparent, or invisible, fishing filament 24 is connected to the top part of the bat 18 in a position where, when suspended therefrom, the bat 18 is balanced and is generally level with the wings 30 extending horizontally and outwardly. The end of the transparent filament 24 is connected to the top of the bat 18 with a hook (not shown). The hook is fastened to the end of the filament 24, and then the hook is inserted into the Styrofoam body of the bat 18 and bonded with a hot glue. Feathers are also attached to the Styrofoam body using a glue.
(13) The opposite end of the transparent filament 24 is threaded through the elastic band 22 and connected to a conventional button 32 having two or more holes for a thread. The button 32 can be constructed of plastic or other suitable material. The transparent filament 24 is connected to the button 32 using a knot, glue or other suitable means.
(14) The elastic band 22 can be constructed of conventional elastic material, but could be any other material that stretches and can clamp onto a fan blade 16. Conventional elastomeric, elastic and other type of stretchable bands can be utilized. Indeed, the elastic band 22 could be a heavy duty rubber band, or other elastomeric material. The elastic band 22 includes a length suitable for stretching around conventional fan blades. When the fan blade to be used is of an unusual design, such as a leaf, the elastic band can be constructed with a length to accommodate the larger type of fan blades. Otherwise, the elastic band 22 can be constructed with suitable lengths for stretching around standard-size fan blades 16.
(15) The elastic band 22 can be constructed as an endless item, but can be constructed with ends 34 and 36, as illustrated. The ends 34 and 36 are sewn together in an overlapping manner so that the band 22 has a double thickness at the area where the transparent tether 24 passes therethrough. This feature allows somewhat more pressure to be placed on the button 32, against the bottom surface of the fan blade 16.
(16)
(17) In order to further prevent inadvertent rotation of the button 32, the button 32 itself can be constructed with a material that exhibits a high friction, such as a soft elastomeric material, or can be constructed with a covering or outer layer of a high friction material, such as a rubberized coating. The enlargement 32 fastened to the top end of the invisible filament 24 could also include sharp or rough edges or other arrangements that resist rotation of the enlargement 32 with respect to either the bottom surface of the fan blade 16 or the top surface of the elastic band 22, or both.
(18) In practice, the invisible filament 24 is fastened to the button 32 or other type of enlargement so that the filament 24 cannot rotate within the button 32 or enlargement. To that end, top end of the invisible filament 24 is threaded through more than one holes of the button 32 and then appropriately tied in a knot (not shown). This contrasts with threading the top end of the invisible filament 24 through just one button hole and tying a knot so that it cannot be pulled back through the button hole. In this latter practice, the top end of the invisible filament could turn within the button hole together with the knot.
(19)
(20) In
(21)
(22) In this embodiment, the enlargement, or the button 32 in the illustration, is not entirely captured between the hook and loop strips 44 and 46. Rather, a portion of the button 32 on each side of the loop material 46 is exposed so that the user can grasp the opposite sides of the button 32 and manually rotate it to achieve a different orientation of the airplane 50 with respect to the invisible filament 24.
(23) Those skilled in the art may prefer to provide a rotational arrangement at both the top end of the filament and at the bottom end of the filament so that the orientation of the object can be adjusted at either end of the invisible filament. The same or different types of rotational arrangements can be employed at both ends of the filament line.
(24) While the preferred and other embodiments of the invention have been disclosed with reference to specific rotational arrangement components, and associated methods of fabrication thereof, it is to be understood that many changes in detail may be made as a matter of engineering choices without departing from the spirit and scope of the invention, as defined by the appended claims.
