FIELD OF TECHNOLOGYEmbodiments of the present disclosure are directed to recreational disks, and more particularly, to recreational disks that incorporate blade members to selectively adjust flight dynamics of the recreational disks.
SUMMARYAccording to some embodiments, the present disclosure is directed to a recreational disk comprising: (a) a disk body comprising an upper surface and a lower surface; (b) a first plurality of radially arranged blades rotatably supported on any of the upper surface and the lower surface of the disk body, the first plurality of radially arranged blades rotating during flight so as to change at least one aerodynamic behavior of the disk body, compared to the disk body without the first plurality of radially arranged blades; and (c) a motor that rotates the first plurality of radially arranged blades when the recreational disk is thrown through the air.
According to some embodiments, the present disclosure is directed to a recreational disk comprising: (a) a disk comprising an upper surface, a lower surface, and an outer rim formed by a protrusion that extends circumferentially around an outer edge of the disk; and (b) an airfoil assembly comprising: (i) a shaft that is rotatably supported in a center of the disk; and (ii) a first set of airfoils that are directly coupled to spokes that extend perpendicularly to the shaft, wherein rotation of the shaft causes the airfoils to rotate so as to produce lift when the disk is thrown through the air.
The accompanying drawings, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed disclosure, and explain various principles and advantages of those embodiments.
The methods and systems disclosed herein have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
Devices of the present disclosure include recreational disks that have flight altering components that change or alter at least one aerodynamic behavior of the disk when the disk is in flight. For context, the shape of a recreational disk in combination with a user imparting spin on the disk when the user throws the disk creates lift. That is, the spinning of the disk when thrown creates lift on the disk. The present disclosure describes embodiments of recreational disks that incorporate blade members that increase lift forces on the recreational disks. This is what is referred to as changing or altering an aerodynamic behavior of the recreational disks. These aerodynamic behaviors are altered when compared to the same recreational disk without such blade members.
In some embodiments, the blade members are in fixed relationship to a disk body. In other embodiments, the blade members can rotate relative to the disk (e.g., rotatably supported on/by the disk body).
In various embodiments, a recreational disk can comprise multiple sets of blade members. Some embodiments include the blade members being radially arranged to resemble turbine blades. The blades can have unique geometrical configurations that include variances in cambering, twisting, angle of attack, and cross-sectional size along chord length—just to name a few.
Referring now to
The disk 100 can be manufactured from any number of suitable materials that would be known to one of ordinary skill in the art with the present disclosure before them.
The disk 100 comprises a first plurality of radially arranged blades 110 that are arranged around a hub 112. The hub 112 can be rotatably coupled with a shaft 114 that is fixed to the disk body 102. To be sure, the first plurality of radially arranged blades 110 mounted to the hub 112 can freely rotate around the shaft 114 independently from rotation of the disk body 102 itself. In some embodiments, the first plurality of radially arranged blades 110 are directly or indirectly mounted to the shaft 114. The shaft 114 is rotatably supported at a central axis A of the disk 100, according to some embodiments.
In one embodiment, the blades 110 extend away from the hub 112. The blades 110 each have a cross-section and size that varies according to performance and/or design requirements, such as how much additional lift is required or desired (other embodiments can reduce lift as explained herein). When arranged onto the hub 112, the blades 110 comprise cambering and/or twisting that produce a right-handed effect or a left-handed effect. That is, the arrangement of the blades 110 onto the hub 112 will cause the first plurality of radially arranged blades 110 to rotate either clockwise or counterclockwise during flight, based on their right-handedness or left-handedness.
When the blades 110 are arranged in such a way that they spin in a direction that is opposite to a spin direction of the disk body 102, the blades 110 will reduce lift produced by the disk 100. Conversely, when the blades 110 are arranged in such a way that they spin in a direction that is equal to a spin direction of the disk body 102, the blades 110 will increase lift forces on the disk 100.
In some embodiments, rather than being rotatably supported, the blades 110 can be held in a fixed position such that the hub 112 cannot rotate relative to the shaft 114.
In use, when the disk 100 is rotated and thrown by a user, the first plurality of radially arranged blades 110 will rotate during flight so as to change at least one aerodynamic behavior of the disk 100. This change in aerodynamic behavior is determined in relation to the disk 100 without the first plurality of radially arranged blades 110.
The blades 110 can include additional or fewer blades than those illustrated in the drawings. Additionally, the blades 110 can be manufactured from the same materials used to construct other portions of the disk 100 or different materials.
As mentioned above, the blades of both the first of radially arranged blades 304 and the second set of radially arranged blades 308 have specific geometries that affect the amount of lift produced thereby. In some embodiments, the shape, size, number, and otherwise arrangement of blades on each of the sets of radially arranged blades 304 and 308 can be identical between the first and second sets of radially arranged blades 304 and 308. In other embodiments, the blades of the first set of radially arranged blades 304 comprise a first configuration (e.g., cambering, twisting, angle of attack, and cross sectional size along chord length) and the blades of the second set of radially arranged blades 308 comprise a second configuration. The first and second configurations can be different from one another. In one embodiment, the first set of radially arranged blades 304 have an overall diameter D1 and the second set of radially arranged blades 308 have an overall diameter D2. In some embodiments, the diameter D1 is greater than the diameter D2, although these diameters can be equal to one another. In other embodiments, the diameter D2 is greater than the diameter D1.
Again, the configuration of each of the first set of radially arranged blades are selectable according to performance and design requirements. In some embodiments, a terminal end 614 of a blade body 616 of each of the blades, such as blades 608, has a length L1 that is greater than a length L2 of an opposing end of the blade body 616 that couples with the inner sidewall 606. This configuration allows a portion of the first set of radially arranged blades to extend above an upper surface 618 of the annular ring 604, while allowing a portion of the first set of radially arranged blades to extend below a lower surface 620 of the annular ring 604. That is, a shape and size of the blades cause the blades to terminate along an upper reference line R1 that is disposed at an angle θ1 that is defined relative to the central axis CA of the recreational disk 600. Moreover, the shape and size of the blades cause the blades to terminate along a lower reference line R2 that is disposed at an angle θ2 that is also defined relative to the central axis CA of the recreational disk 600.
In various embodiments, the annular ring 604 comprises an outer rim formed by a protrusion 622 that extends circumferentially around an outer edge 624 of the annular ring 604, generally referred to as the disk body 602.
In one embodiment, the flat disk body 702 comprises a central aperture 708. The annular ring 704 forms collar above the central aperture 708 of the flat disk body 702. In some embodiments, the blades 706 are disposed within the annular ring 704. The blades 706 extend from a lower edge of the annular ring 704 to an upper edge of the annular ring 704. The blades 706 can have any desired configuration as mentioned above. The annular ring 704 with blades 706 can be disposed above or below the disk body 702, protruding both above and/or below a plane of the disk body 702.
In
In some embodiments, a motor 1012 is positioned within the first turbine 1002. This motor 1012 provides a rotational force to either or both of the first turbine 1002 and the second turbine 1006. According to some embodiments, the motor 1012 is configured to operate via a switch 1014 that places the motor 1012 in an off or on position. In other embodiments, the motor 1012 is configured to rotate either the first turbine 1002 and/or the second turbine 1006 when the disk 1000 is thrown through the air. That is, when the force of the air moving over the first turbine 1002 or the second turbine 1006 during use, the motor will engage and begin to spin either or both of the first turbine 1002 and the second turbine 1006.
In various embodiments, an accelerometer 1020 or other motion sensing device can be used to sense motion of the disk 1000 and use this motion sensing information to engage the motor 1012 through the microprocessor 1016. That is, if the acceleration of the disk 1000 meets or exceeds an acceleration threshold, the motor 1012 is engaged to spin the turbine(s).
In some embodiments, the motor 1012 comprises a microprocessor 1016 that allows the motor 1012 to be controlled via remote signaling. For example, the disk 1000 can comprise a wireless communications interface that operates using any of WiFi, cellular communications, near-field communications, Bluetooth, and so forth. The motor can be switched off and on by a user's mobile device. By way of example, an application can be executed on a mobile device to control operations of the motor 1012.
The disk 1000 can also comprise a rechargeable battery 1018 that powers the motor 1012 and microprocessor 1016.
The application can provide, in some embodiments, a unique user interface that allows the user to switch the motor 1012 between on and off modes of operation.
In some embodiments, the airfoil sub-assembly 1202 can be above or below the disk body 1206. In other embodiments, two airfoil sub-assemblies can be used, one above and one below.
An optional motor 1218 can be utilized to rotate the shaft 1204 of the airfoil sub-assembly 1202. In various embodiments, the recreational disk 1200 can comprise the microprocessor and wireless communications interface described in the embodiment of
An optional motor 1408 can be utilized to rotate a shaft of an airfoil sub-assembly 1420. In various embodiments, the recreational disk 1400 can comprise the microprocessor and wireless communications interface described in the embodiment of
