Nets used for backyard or recreational badminton, volleyball and other net-sports can be burdensome and time consuming to initially set up because it typically requires the user to attach eyebolts or brackets with eyelets to the support poles and then tie the top and bottom net cords to the eyes. Additionally, when it comes time to take down the net, many users find it too time consuming and burdensome to untie the knots to remove the net from the poles and so they simply role the whole net assembly up around the poles. By not removing the net from the poles, the net becoming tangled with the guy-ropes other net components or the net will become entangled with other items where the net is stored thereby making it more burdensome and time consuming to set up the net the next time it is desired to be used.
Accordingly, there is a need for a sports net assembly that simplifies the initial set and subsequent set ups of the net and which makes it just as simple to disassemble the net after game play so as not to discourage users from completely disassembling the net from the support poles for proper storage. Additionally it is desirable to incorporate into the sports net assembly a simple and effective way to adjust and maintain the desired tension on the net during game play.
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views,
The sports net assembly 10 includes a net 12 operably supported between spaced apart support poles 14 by a top net cord 16 and a bottom net cord 18 utilizing the net attachment and tensioning system 100 (discussed later). Guy-ropes 20 are provided to stabilize and hold the poles 14 so the net remains in place during game play and to resist the tendency of the poles to tip inwardly under the weight of the net 12. The guy-ropes 20 are secured at one end to the ground by stakes 22. The other end of the guy-ropes 20 are preferably releasably attached to the poles 14 as described later. Length adjusters 24, as are well known in the art, may be provided to allow the user to adjust the length of the guy-ropes 20 as desired to adjust and plumb the poles and/or to increase or decrease tension or pull on the net 12 to reduce sag in the net between the poles.
The poles 14, may comprise a single pole or a number of pole sections which fit together. The poles 14 are preferably thin-walled tubular members such that the poles are light weight yet sufficiently rigid to adequately support the net without buckling. The cross-section of the tubular members may be round, square or other shape to provide the desired rigidity. In a preferred embodiment, the poles 14 include a ground member 30 having a pointed end 32 that is hammered into the ground as an anchor for the poles. A pole receiving end 34 of the ground member 30 preferably projects a distance above the ground to be telescopically received by the bottom end 36 of the tubular pole member. The ground engaging member 30, is preferably configured and made of a material that can withstand repeated hammering without the pole receiving end 34 mushrooming or becoming deformed.
The net attachment and tensioning system 100 preferably includes a pair of pole caps 102. Each pole cap 102 preferably sits over the top end of each pole 14 or is otherwise secured proximate the top end of each pole. The pole cap 102 has first and second hooks 104, 106 through which a length of the top net cord 16 passes as best illustrated in
The net attachment and tensioning system 100 also preferably includes a cam 110 that is slidably disposed along the pole 14. The cam 110 includes a slot 112 into which the top net cord 16 is removably receivable. A ball or knot 114 is preferably provided at the end of the top net cord 16 to prevent the top net cord from pulling through the slot 112. The cam 110 includes an aperture or opening 118 (
In a preferred embodiment, the cam 110 is preferably made of a substantially rigid material so that it will not bend or deform under the pulling force or tension exerted by the top net cord 16 received within the slot 112. It is also preferred that the aperture walls 120 are made of material with a high friction factor, such as rubber to provide a better frictional lock to resist sliding of the cam relative to the pole. To provide the desired rigidity while at the same time providing the desired high friction rubber material at the aperture walls 120, the cam 110 is preferably fabricated using a double injection molding process wherein the body of the cam is made of plastic or other suitably rigid material while the aperture walls are made of rubber or other high friction factor material.
Referring to
It should be appreciated that the foregoing net attachment and tensioning system 100 simplifies the attachment of the net and guy-ropes to the poles during initial set-up and makes the disassembly of the net and guy-ropes from the poles just as easy and efficient so users are not discouraged from completely disassembling the net and guy-ropes from the poles during take-down of the net after game play. As such, each subsequent set-up of the net follows the same simple procedure as the initial set up. Furthermore, the net attachment and tensioning assembly 100 provides a simple and effective way to adjust and maintain the desired tension in the net during game play by simply sliding the cams 110 up and down relative to the poles 14.
The foregoing description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiment of the apparatus, and the general principles and features of the system and methods described herein will be readily apparent to those of skill in the art.
