Abstract: A boomerang includes a central disk comprised of concentric inner and outer rings that are connected by radially extending connection sections. Wings radially extend from an outer circumference of the outer ring, corresponding in position to the connection sections. The inner ring defines a central bore. Arc openings are formed between the inner and outer rings and delimited by the connection sections. Aligned openings are defined in each wing and the associated connection section. Tabs extend from edges of the openings in opposite directions and also incline in opposite directions. Further tabs are formed on and extend from an inner circumference of the outer ring. When the boomerang flies, the central bore, the arc openings, and other openings allow airflow to pass therethrough, while the tabs impose constraints to the airflow to induce stable and extended flying of the boomerang in the air.

Abstract: A boomerang is made from a flat sheet material, and includes interconnecting portions angularly displaced from one another about a center point, and terminating at an arc boundary that cooperates with the center point to define a radius, and blades integrally and respectively formed with the interconnecting portions. Each blade has a bent line which extends from an outer point at a distal edge to an inner point at the arc boundary, and which is of a length that is equal to the radius. The bent line meets a radius line at the arc boundary to form a vertex with an included angle of obtuseness. Varying the interior angle formed by each of the bent line and the radius line with a base line interconnecting the outer point and the center point can change flight patterns of the boomerang.

The launcher includes a stop (23), against which the object rests at a point (27) on its body. A moving member (25) engages one of the wings of the object so as to impart forward motion thereto, such that the object is propelled forward from the launcher with a rotational moment about the stop. The boomerang is preferably made from a sheet (50) of material which is cut to form the plurality of wings, joined at a vertex (28), wherein one or more of the wings are folded to produce lift flaps (34, 35).

Abstract: The present invention is a boomerang flying toy having a plurality of blade arms with airfoil-like tapered perimeter edges along their respective cut lines to give the boomerang toy improved aerodynamic performance characteristics. The blade arms extend radially outward at equal angles from a central hub, where they are coupled together by interlocking fastener plates or self-adhesive decals affixed to the top and bottom surfaces at the junction of the blade arms. The top and bottom surfaces have optically perceived indicia to increase the toy's appearance and can be used to display a wide range of information including graphics, logos, advertisement, sales, and promotional information. An additional flying ring toy is die cut at the same time as the boomerang with only two additional circular cuts. The flying ring toy has the same enhanced flight performance and optically perceived indicia.

Abstract: A flying toy of the boomerang type utilizing circular airfoils in the form of disks comprising a main disk (10) with a plurality of control disks (12) or (36) affixed to its perimeter at their perimeters, sufficient to provide rigidity and lying in a generally common plane forming a homogeneous one-piece unit. When thrown overhand so as to rotate through the air the combination of disks creates lift throughout 360° of boomerang's rotation. The result is a safer, more balanced and stable boomerang that is easy to throw and catch. The specific arrangement of disks provides a profile suggestive of and suitable for application of a variety of cartoon faces such as mice, dogs or bears making a desirable wall hanging when not in use.

The assembly includes a sheet of cardstock or thin printable sheet material, a sheet of transparent laminated plastic and intermediate adhesive layer that adheres the cardstock sheet and laminated sheet together. The cardstock sheet has a die cut outline configured to the desired shape of an object. The laminated sheet has a die cut outline substantially extending outside of the outline on the cardstock sheet, to allow laminated sheet to fold over and entirely cover the cardstock area within the cardstock die cut outline. The assembly has a substantially constant thickness and substantially flat upper and lower surfaces so that the assembly can pass through a printer or copier without jamming.

Abstract: A flying toy in the form of an aerodynamic flying ring. An annular disk (17) surrounds a central opening (12) to create a ring. A convex upper surface (11) deflects air flowing over the top side of the disk, increasing air speed and reducing downward air pressure. An aerodynamic protruding annular fin (27) located near the inner perimeter (18) of the unit deflects air upward again, increasing air speed and decreasing air pressure again. The lower side of the unit contains an undercut that can be straight (16), curved (20), or angled (22). This undercut creates a lower cutaway surface (19) which may be parallel to, or at an angle to, the horizontal plane. This structure captures air beneath the unit, slowing air speed and increasing upward air pressure on the unit. These features combine to provide greater lift capacity than any of them would produce separately. In the preferred embodiment the disk is made of a soft foam material such as polyethylene or polyurethane, but other materials could be used.

Abstract: A thin, planar flying toy has a plurality of radially extending, equiangularly spaced, relatively constant width arms extending from a central hub. Each arm has a given length that is substantially greater than the width of each of the arms. The central hub and the arms lie substantially within a common plane with the edges of the arms extending substantially perpendicularly between the first and second surfaces. The process for producing the flying toy includes cutting a planar sheet of plastic material to define the planar body that includes the central hub from which relatively constant width, equiangularly spaced arms radially extend. The material can be translucent with translucent or opaque indicia thereon to produce optically perceived patterns in flight.

Abstract: A boomerang with three convolute curved blades connected to a central hub, said blades being uniformly shaped and equally spaced about a central axis and has unique airfoil characteristics around the entire peripheral edge, the unique airfoil characteristic is an integral part of this invention; when the boomerang is thrust outwardly in a vertical position, it will create and maintain a forward flight pattern from the point of launching; it subsequently begins an upward flight until it momentarily stalls in the air, then makes a 180 degree turn to the left, reverses its forward flight and simultaneously rotates 90 degrees from vertical, taking on a horizontal, hovering type of flight pattern, and slowly returns to the point of launching; said forward and return flight pattern is desirable for safety as well as the appeal it has for competing in sporting events and tournaments as well as leisure play activities.
