DETAILED DESCRIPTION OF THE INVENTION

[0033] With reference to the drawings, a new and improved game net embodying the principles and concepts of the present invention will be described.

[0034] In FIG. 1, there is shown an exemplary embodiment of the game net of the invention, which is generally designated by reference number 10. In its preferred form, the game net 10 has a netting 12 forming a planar, vertically oriented barrier that defines an opening 14 through the barrier. The opening 14 is disposed, generally centrally in the netting such that the netting forms a wall or barrier around the opening. The opening 14 can be thought of like a window through the netting 12 that is surrounded by netting along each side of the opening.

[0035] Further, as depicted in this embodiment, the netting 12 includes side panels 13a and 13b that extend along the opposite, vertical sides of the opening 14. In an alternative arrangement, as seen in FIG. 3, netting 12 can be provided without the side panels 13a and 13b.

[0036] The netting 12 is attached to and supported by a frame 16 such that the netting is supported upon a ground surface and extends vertically upward therefrom, thereby providing the vertically oriented barrier. Netting 12 is attached to and supported by the frame 16 such that the netting maintains its shape. The frame 16 can include a pair of spaced apart vertical frame members 18 and 20. And can include a plurality of horizontal frame members 22, 24, 26, and 28 that are connected to and extend between the vertical frame members 18 and 20 at spaced vertical distances between one another. The frame 16 further includes a pair of ground engaging support leg assemblies 30 and 32.

[0037] It is important to understand the depicted frame 16 is representatively illustrated and the frame could take on various other constructions while remaining within the scope of the invention. For example, while not shown herein, the frame 16 can be collapsible to provide for easier storage and transport of the game net 10.

[0038] Further yet, the net 12 and the frame 16 can be constructed to permit adjusting the height of the opening or window 14 from the ground (GH), the dimensional width of the opening side-to-side (WW), and the dimensional height of the opening from top-to-bottom (WH).

[0039] Netting 12 may include sleeves, such as, for example sleeves 34, 36, and 38 through which sections of the frame 16 may be disposed or extend through to secure the netting 12 to frame. The netting 12 may include more or fewer sleeves than depicted here and as needed to attach the netting to the frame. An example of an alternative construction of the game net 10 and netting 12 is shown in FIG. 2, wherein netting further includes sleeves 37 and 39.

[0040] Additionally, other means such as, for example, straps, clasps, buttons, cords, etc. could also be used in connection with the sleeves or as alternative to the sleeves to secure the netting 12 to the frame 16.

[0041] In FIG. 4, there is shown an alternative construction of game net 10. As depicted here, the game net 10 has a similar construction to the game net shown in the prior figures. As shown here, a border 40 arranged it attached to the netting 12 around the opening 14. Border 40 serves several functions, including delineating the opening 14 and to provide support to the netting 12 around the opening. Border 40 could be colored with a bright color to give players a better visual identification of the opening 14.

[0042] As further shown here, a plurality of elastic cords 42-48 can be attached to the netting 12 to keep the netting pulled tight at the opening 14, keeping the opening fully open at its extents. As representatively shown, elastic cords 42-48 can each extend from a respective corner of the border to a corresponding corner of the netting 12, as shown. The elastic cords 42-48 could be arranged in different locations so long as the same purpose of keeping the opening 14 fully open is provided.

[0043] In FIGS. 5-7, there is shown an alternative construction of game net 10. As depicted here, the game net 10 has a similar construction to the game net shown in the prior figures. However, in this embodiment, the netting 12 is replaced by panel 50 that is supported above a ground surface by attachment to frame 62, for example. Like the forgoing embodiment, panel 50 has the opening 14 and a border 52 disposed around the perimeter of the opening. Border 52 could be colored with a bright color to give players a better visual identification of the opening 14. Panel 50 can be removably attached to the frame by mechanical fasteners, such as, for example matting touch fasteners, wherein one half of the fastener 54 is disposed on the frame and the other half is 56 is disposed around the perimeter of the panel 50, along one broadside thereof.

[0044] Preferably, panel 50 is constructed of a transparent material, thereby allowing players located on opposite sides to see one another through the panel. In embodiments, it is contemplated that the panel could be created from a single piece of rigid, transparent plastic material. In other embodiments, it is contemplated that the panel could be created from a single piece of flexible, transparent plastic material, that could be rolled up for storage and unrolled for attachment to the frame 62.

[0045] With reference to FIGS. 8 and 9, in embodiments, it is contemplated that the panel 50 could be constructed of individual panels 58a-58d that can be removably connected to create the panel 50. The individual panels 58a-58d would be constructed of rigid, transparent plastic material. With further reference to FIG. 10, in an embodiment, panels 58a and 58c could have tabs 60 located at opposite ends that removably secure to panels 58b and 58d to connect the panels together by a mechanical fastener, such as a touch fastener 64, for example.

[0046] With further reference to FIG. 11, it is further contemplated that each panel 58a-58d could be constructed to fold in half to make storage and shipping easier. In such a construction, each panel 58a-58d could comprise two or more sections 66a and 66b that are joined by a flexible coupling 68 along fold joint 70 to fold in half.

[0047] In FIG. 12 there is shown an alternative construction of game net 10. As depicted here, the game net 10 has a similar construction to the game net shown in the prior figures and, particularly, the game net shown in FIG. 4. Like reference numbers refer to the same or similar parts and thus a description of those element does not require repeating here. The construction depicted in FIG. 12 does not include the lower frame cross member 26 and further includes an elastic cord 72 attached to each bottom corner of the net 12 and to the bottom of the frame 16 to pull the net tight in a direction downwardly on the frame.

[0048] Game net 10 is particularly useful in facilitating game play without a lined court. This allows quick and simple setup of the game net 10. The construction further allows for both indoor and outdoor play.

[0049] Generally, in use, players would stand on opposite sides of the game net 10. The players would then, using paddles, hit a shuttlecock, for example, back and forth while attempting to pass the shuttlecock through the opening 14. Game play with net 10 is not limited to a shuttlecock, rather other objects, such as, a ball for example could be used. However, it is desired that the shuttlecock described herein below is used with the game net 10. Various game methods, rules, and scoring can be implemented in connection with the game net 10.

[0050] In FIGS. 13-16 there is illustrated a shuttlecock 100 that is constructed in accordance with an embodiment of the invention. The shuttlecock 100 is constructed, as described in further detail below, to have a controlled flight speed and flight distance making it desirable for use in connection with the foregoing described game net.

[0051] Shuttlecock 100 includes a nose cone 102 and a plurality of feather fins 104. The nose cone 102 is comprised of a solid component that can be made of a resilient plastic or hardened rubber. The nose cone has a rounded end 106 and an opposite end 108. Rounded end 106 is configured to be struck by a paddle or racket. Opposite end 108 is configured for the attachment of the feather fins 104 to the nose cone 102. Particularly, a plurality of blind bores 110 are formed through end 108 and extend axially into the body of the nose cone 102. The bores 110 are equally spaced circumferentially around the central axis 112 around the nose cone 102 at the same radial distance from the central axis.

[0052] As representatively shown, there are six bores 110 formed through end 108 of the nose cone 102 for receiving six feather fins 104, one in each bore. It should be noted, however, that the shuttlecock 100 is not limited to only six feather fins 104 as shown. Rather, the shuttlecock 100 could have additional or fewer fins so long as desired function described of the shuttlecock described herein is provided. For example, the shuttlecock could have between four and eight feather fins 104.

[0053] In an embodiment, feather fins 104 are natural wing feathers and are each from the same wing of a bird, such as, for example a goose. That is all the feather fins 104 are from either the right wing or from the left wing of the bird. Feathers from the left wing are never mixed with feathers from the right wing, this is critical to the desired operation of the shuttlecock 100. Additionally, the length of each feather fin 104, from the feather tip to the end of the calamus (quill) must be between 10 cm and 18 cm.

[0054] The arrangement of the feather fins 104 on the nose cone 102 is also critical to the operation of the shuttlecock 100. Specifically, as best seen in FIG. 16, each feather fin 104 is positioned in its respective bore 110 with the feather shaft 114 in a rotated position such that the natural convex curvature of the inner vane 116 and the outer vane 118 are facing inwardly toward the axis 112. And further that the rotated position of the feather shaft 114 is such that the attachment points of the inner vane 116 and of the outer vane 118 with the feather shaft 114 are at a 90-degree angle relative to a radian line 120 extending from the axis 112 through the axis 122 of the feather shaft as measured at proximity to end 108. Further yet, the feather fins 104 are arranged such that the outer vane 118 of each feather fin is disposed on the inward side (in relation to axis 112) of the inner vane 116 of the immediately adjacent feather fin in an overlapping arrangement such that the leading edge 124 of the outer vane is facing in a direction outwardly (in relation to axis 112).

[0055] Further yet, unlike some existing shuttlecock constructions, none of the feather fins 104 of shuttlecock 100 are joined or otherwise connected along their lengths to an adjacent fin or any other fin attached to the nose cone 102. For the purpose herein, joined or connected means a physical link between fins that constrains relative movement between fins. To avoid uncertainty, for the purpose herein, a mere contact between surfaces of adjacent fins without a physical link that constrains relative movement between the fins is not considered joined or connected.

[0056] The foregoing described selection and arrangement of the feather fins 104 on the nose cone 112 provides the desired operational characteristics of the shuttlecock 100. Specifically, when end 106 of the shuttlecock 100 is struck by a paddle or racket, a spin about axis 112 is induced in the shuttlecock as it flies through the air. This spin imparts a centrifugal force on the feather fins 104, causing the fins to bend or flex outwardly away from axis 112. The outwardly bending of fins 104, during flight, increases the air drag on the shuttlecock 110, which brakes or slows the flight speed of the shuttlecock, and in turn limits the flight distance of the shuttlecock. In embodiments, the flight distance of the shuttlecock 100 is limited to about 18 feet.

[0057] This function overcomes the drawbacks of existing shuttlecocks that can be hit so hard by a player that the shuttlecock flies too fast and too far to be returned by an opposing player, and thus requiring lined courts for fair game play. Accordingly, shuttlecock 100 has the advantage of being played in a game without lined courts while maintain fair game play, which also makes the shuttlecock advantageous for play with the game net described herein.

[0058] While the foregoing description of the shuttlecock 100 is made in connection with its use with game net 10, one of ordinary skill in the art will readily appreciate that the shuttlecock can be used without the game net described herein and thus should not be limited to such use. Additionally, while natural feathers are desired as the feather fins, it is contemplated that manufactured or synthetic feathers that are created to mimic both the form and the physical properties of natural wing feathers could potentially be used and remain within the scope of the invention. Further, it is contemplated that the shuttlecock 100 could have fins 104 that are manufactured in a configuration that would impart the desired spin to the shuttlecock as explained above and have a flexibility allowing the fins to bend outwardly to provide the desired braking action on the shuttlecock, also described above.

[0059] While the invention has been particularly shown and described with respect to the illustrated embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
