473613000 | Having fluid-dynamic means other than stitched seam or textured surface to alter, stabilize, or retard passage of projectile through the fluid (e.g., spiral fluting to impart spin, etc.) | 9 |
20100137081 | BALL - A ball includes a ball body having a spherical surface, and at least one projection extending from the surface of the ball body. The projection extends in such a manner that the projection forcibly separates a laminar boundary layer generated on the surface of the ball body, and transitions the laminar boundary layer to a turbulent boundary layer. | 06-03-2010 |
20100216579 | ROTARY PROJECTILE TOYS - A toy throwing object including a plurality of fins of sufficient flexibility to permit the device to travel in two distinct modes of operation. In a first mode, the device travels ballistically without significant rotation. In a second mode, the device rotates in a helicopter-like fashion. | 08-26-2010 |
20110250997 | Round Ball, Such as a Soccer Ball, Having a Pattern of Fins to Resist Rolling - A ball, such as a soccer ball, comprises a sphere having a surface, a plurality of smooth portions on the surface of the sphere, and a plurality of flexible fin-like projections protruding from the surface. The fin-like projections may have a height of about 7-10 mm in the may be made from flexible and crushable rubbery material with a Shore A durometer reading of about 50-60. One effect is that the ball tends to fly a shorter distance and to stop rolling more quickly than the same ball without the fin-like projections. | 10-13-2011 |
20110275463 | GAME BALL - Hollow balls with a hard shell, for example the game ball used in the pickle ball game, are used in various racquet games. One example of such hollow balls is the game ball used in the pickle ball game. These hollow balls break after a period of use or when excessive force is applied to the hollow ball. A game ball is described herein with a first plurality of apertures and a second plurality of apertures. Each of the first plurality of apertures is dimensionally different from each of the second plurality of apertures and inter-configured to reduce damage to the game ball during use thereof. | 11-10-2011 |
20140235380 | FLYING FOOTBALL WITH LIFT-GENERATING WINGS - A throwing or catching toy includes a generally elongated spheroidal body defined as having a longitudinal axis, where a length of the body along the longitudinal axis between a front end to a back end of the body is longer than an equatorial diameter. A support is attached to the body and extends beyond the back end of the body and does not extend beyond the front end of the body. A lift-generating wing is non-movably attached to the support. A push surface is disposed near the back end of the body, where the push surface is generally perpendicular to the longitudinal axis. A horizontal stabilizer is attached to the support and disposed behind the lift-generating wing. An impact transfer surface is attached directly to the support, where the impact transfer surface is disposed within the body and fixed between the front end of the body and the support. | 08-21-2014 |
20150051031 | Football With Aerodynamic Lace - Lace designs for footballs are provided. The laces have geometries that improve the aerodynamic characteristics of the football during flight. Additionally, the placement of the laces on the football is selected to maximize aerodynamic performance of the football during flight. | 02-19-2015 |
20160067556 | FOOTBALL BODY WITH ANNULARLY DISPOSED AIRFOIL - A throwing or catching toy includes a first body defined as having a longitudinal axis. A length of the first body along the longitudinal axis between a front end of the first body to a back end of the first body is longer than an equatorial diameter of the first body. A generally cylindrically-shaped annular second body is disposed about the first body aligned along the longitudinal axis. A connection structure is disposed and connected between the first body and the second body, where the connection structure secures the first body in a fixed position relative to the second body. | 03-10-2016 |
20160082323 | FLOATING SOCCER BALL - For an aerodynamic soccer ball, a shell with a hollow interior is provided. A plurality of orifices are disposed and uniformly spaced on the shell. | 03-24-2016 |
20160131462 | Long-Range Aerodynamic Pellet for Airsoft and Military Training - The invention relates to a variety of pellets for using in the sport Airsoft and for military training, said pellets being novel in that they have a more aerodynamic design based on a surface that reduces the air friction and allows a longer range. Said pellets are characterized in that they have a surface forming different geometric figures such as a hexagon, pentagon, triangle, circle or square, that create a turbulent flow in the surrounding air layers, thereby obtaining a longer range and improved shooting precision. | 05-12-2016 |
