Definitions

  • This invention relates to toys specifically to elastomer launched aerial toys that spin during descent.
  • a problem in general with launched aerial toys is that the weight of the toy directly affects the height to which the toy can be launched by the elastic band.
  • a toy that is 10 grams cannot be launched to the same height as a toy that is 5 grams.
  • Most aerial toys have a significant weight, over 5 grams, which limits the height they can be launched. Because the weight limits the maximum height the toy can be launched, the maximum time the toy can stay airborne is also limited. In addition, besides affecting the launch height, the weight also speeds the toy's descent to back to Earth.
  • the toy's weight must be decreased. Unfortunately, the lighter the toy is, the more it will be affected by air resistance during ascent. Previously it has been extremely difficult to launch an aerial toy with a weight of under two grams (superlight) to significant heights (over 15.24 meters , 50 feet ) because the force of the air resistance encountered during ascent is more than enough to stop the toy's upward momentum. Air resistance is encountered by the hooking mechanism that allows the toy to be launched, the weighted or thicker areas that help maintain proper orientation during launch, and by the winged surfaces that are necessary for spinning or gliding during descent.
  • aerial gliding toys exist. These toys are subject to the same physics problems as the spinning toys.
  • An additional problem with the aerial glider toys is that the same aerodynamic profile that allows the toy to be launched also causes the toy to return to Earth very quickly unless it happens to catch an updraft. In general, gliding toys return to Earth even faster than the spinning toys.
  • FIG. 1 provides an example flight path of the invention showing the rotation of the invention during ascent and descent.
  • FIG. 2 provides a representative of the invention orientated against a standard height, width, depth coordinate system.
  • FIG. 3 provides an enlarged frontal view of the invention and the launching apparatus.
  • FIG. 4 provides a frontal view of the invention showing the invention construction.
  • FIG. 5 provides a side view of the invention showing the invention construction.
  • FIG. 6 provides a different side view of the invention including an enlarged side view of the invention construction.
  • FIG. 7 provides a frontal view of a second embodiment of the invention.
  • FIG. 8 provides a frontal view of a second embodiment of the invention with surface decoration making the invention appear like a butterfly.
  • the preferred embodiment as shown in Figs 4, 5, and 6 comprises a generally flattened, thin body shape of lightweight and rigid construction.
  • the interior rigid structure 10 can be made of a foamed plastic such as expanded or extruded polystyrene. Balsa wood, paper, paperboard or other like materials can also be used.
  • the interior rigid structure 10 has a surface height that is longer than its width and/or a difference between the amount of surface area contained in the top and bottom half of the invention (height being the longest axis as shown in Figure 2).
  • the height/width ratio is necessary for the toy to rotate around the long axis during descent
  • the difference in surface area is necessary for the toy to exhibit a spiraling motion in addition to the rotational motion around the long axis during descent as shown in Figure 1
  • the interior rigid structure 10 in the preferred embodiment has a shape of an oval intersecting a triangle Other shapes are possible.
  • the height of the structure surface is of greater length than the width.
  • the overall height of the structure is 8 89 centimeters (3.5 inches), and the width is 5.715 centimeters (2.25 inches) at its widest point
  • the second preferred embodiment is shaped like a butterfly Surface decoration is added to enhance the butterfly appearance Again, the height is longer than its width There is a notch 20, on either side, for the elastic band 14 to engage
  • the overall height of the structure is 8.89 centimeters (3 5 inches), and the width is 6 35 centimeters (2 5 inches) at its widest point
  • the interior rigid structure 10 has a thickness of 1 5875 millimeters ( 0625 inches) to .79375 millimeters ( 0375 inches) if made of foamed plastic Thinner materials such as paper and balsa wood are also useable if they are light and rigid enough to withstand the forces during launch. Since rigidity decreases as thickness decreases materials with internal structures such as cells and air pockets are most effective.
  • the interior rigid structure 10 is of weight less than 1 gram
  • the flexible protective outer surface and aerodynamic edge 12 covers the interior structure on both sides of the invention as shown in Figure 6 In addition, it extends beyond the interior structure's outline by approximately 3 175 to 9.525 millimeters (1/8th to 3/8ths of an inch) and connects with itself to form the aerodynamic tapered edge
  • the outer surface extends the interior rigid shape in every direction as shown in Figure 4 At the bottom of the invention where the elastic band will be placed during launch the flexible outer surface is removed so it won't be bent by the launch forces
  • the flexible protective outer surface and aerodynamic edge 12 can be made from any flexible thin plastic such as polypropylene packaging tape which has a thickness of .05334 - 1067 millimeters Similar thin plastics or paper products can also be used effectively
  • the flexible protective outer surface and aerodynamic edge 12 has adhesive backing so that it will adhere to the interior structure and also to itself around the edges forming an aerodynamic tapered edge of thickness less than .2 millimeters.
  • the outer surface 12 colorful designs in waterproof ink can be printed.
  • the outer surface can also be made from several light altering plastics including diffracting, iridescent, and fluorescent materials.
  • the protective outer surface 12 can be translucent, transparent or opaque.
  • light producing chemicals such as luminescent paint, or bioluminescent materials may be added to the outer surface for nighttime amusement.
  • the interior rigid structure 10 and flexible outer surface 12 can also include holes to cause air to resonate and produce sound during ascent.
  • interior rigid structure 10 can be molded to have a tapering aerodynamic edge, then the flexible outer surface may be disregarded altogether. Light altering and/or producing materials can then be placed directly on the interior rigid structure.
  • the dowel 16 that supports the elastic band 14, as shown in Figure 3 can be made of plastic or wood or similar rigid material. A length of 20.32 centimeters (8 inches) and a diameter of .635 centimeters ( 1/4 inch ) works well for the dowel.
  • the dowel contains a notch 18 to hold the elastic band. The notch is deep enough and thin enough to hold the band securely during repeated launches.
  • the elastic band 14 can be put in the notch 18 as in the preferred embodiment. If no notch is present, the elastic band can be looped around the dowel in a slip knot.
  • the Elastic Band 14 works well if it is a rubber band of length 15.24 centimeters (6 inches ), width .9525 centimeters (3/8ths of an inch ), and depth .318 centimeters
  • the toy is launched by holding the dowel 16 steady with one hand, placing the toy between the two surfaces of the elastic band 14, as shown in Figure 3, and pulling the elastic band and the toy down and slightly to the left if being released with the left hand as shown in Figure 1.
  • the elastic band When the elastic band is released, it imparts a natural spin on the toy causing it to rotate counterclockwise if being pulled down with the left hand as shown in Figure 1.
  • This rotation gives the toy gyroscopic stability or rotational inertia during the launch.
  • the gyroscopic stability allows the toy to maintain its orientation and its aerodynamic profile during ascent. As the toy continues upward, air resistance slows the initial rotation. When the rotation slows enough, the toy loses its gyroscopic stability and begins to become unstable.
  • any perturbation of the toy around the shorter axis causes a rotation around the longer axis as shown in Figure 1.
  • This new rotation around the longer axis causes the toy to maintain an air retarding profile allowing it to descend very slowly.
  • the toy will also exhibit a spiraling pattern during descent.
  • the spiraling pattern is caused by a difference in surface area subject to air resistance on each half of the toy.
  • the half with more surface area will be pushed by more air resistance causing the toy to spiral while descending, as shown in Figure 1. If the toy does not have a surface area difference between top and bottom half, as in the second preferred embodiment, it will still descend very slowly but will not spiral.
  • a second preferred embodiment of the invention is shown in Figures 7 and 8.
  • This second preferred embodiment does not have a surface area difference between top and bottom half and does not spiral during descent. Again, because one axis of the toy surface is longer than the other, this embodiment also rotates around its longest axis during descent allowing it to descend very slowly, but without spiraling. Thus, the second preferred embodiment descends differently than the first preferred embodiment.
  • the aerial toy of my invention overcomes the air resistance problems previously encountered in attempts to launch a superlight toy to significant heights, thus providing a higher flying, slower descending aerial toy than has been designed previously.
  • my invention can stay airborne longer than previous similar inventions, it can be tracked and caught more easily.
  • my invention has a variable surface area that can be cut into amusing shapes which can further be enhanced by the addition of colored designs, light altering materials, and light producing materials.

Abstract

Un jouet volant lancé par un élément élastomère est composé d'un corps et d'un mécanisme de lancement. Le corps, selon l'invention, se présente sous forme d'une structure rigide généralement aplatie, mince et légère (10), dotée d'un bord à rétrécissement aérodynamique (12). Ce corps est plus haut que large, et, sur une moitié de sa hauteur, présente une surface plus grande que sur l'autre moitié. Il est conçu pour maintenir un profil aérodynamique par rotation autour de son axe le plus court pendant son ascension, et présente une forme qui privilégie naturellement la rotation autour de son axe le plus long au cours de la descente. Le mécanisme de lancement est conçu pour projeter le corps vers le haut et lui appliquer une rotation autour de son axe le plus court.
