The present invention broadly concerns a net system. More particularly, the present invention concerns a sports net system that allows for the adjustment of the sports net above the support surface and that may further accomplish a uniform tension of the net. The present invention is also directed to a method of positioning a net above a support surface.
Society enjoys recreation. It is a welcome relief from work and can be a means of socialization and exercise. Playing a game of badminton or volleyball in the backyard or local park has long been a weekend pastime. A number of recreational activities including tennis, paddleball, badminton, volleyball, soccer and other such court games require a net as part of the game. The net is used to demark a boundary or to provide an interference surface for the ball or game piece. Conventional nets consist of a tensioned web of flexible material that is suspended between poles, or posts, at each end. Some net systems are permanent while others are portable and can be erected on a chosen playing surface. A desirable feature of portable nets is ease and simplicity of their erection.
A conventional net system is erected by affixing two vertical poles directly into the ground or into a stand and then suspending the net between them. The net is tied or otherwise attached in a manner that places a uniform tension on the net and locates the net at a height and orientation to the playing surface that is desirous for the particular game. Some conventional net poles have fixed net attachment points on them making it difficult to align and position the net when the poles are on uneven ground. The net is attached by either tying it to the pole or by attaching it with fixed length clips. It can be difficult to adjust the poles and mount the net so that there is generally a uniform tension across it, which is usually the desirable configuration. With time, a net may get stretched out of shape and thus may not remain rectangular in shape. In cases where flexible poles are used, the act of tensioning one corner of the net can cause flexure in the pole and change the tension already achieved on the opposite corner thus making the net mounting a tedious, iterative process.
There exists a need for a sports net system that provides for simple adjustability of the net height with respect to the poles so that one may move either end of the net up or down along the pole to attain the proper positioning of the net. There is also a need for adjustability of the net poles so that a generally uniform tension can be achieved in the net in a simple manner.
It is an object of the present invention to provide a new and useful system for supporting a net between support poles.
A pole assembly is provide that is adapted to support an edge portion of a net that is to be suspended above a surface. The pole assembly generally includes a support pole adapted to be positioned in an upright manner relative to the surface, a net pole adapted to secure to the edge portion of the net to be suspended, and a bracket. The bracket is adapted to connect the support pole and the net pole to one another and operative to permit the support pole and the net pole to be oriented with respect to one another at selected relative orientations. At least one fastener or fastener means is provided that is operative to releasably secure the support pole and the net pole at a selected relative orientation.
The support pole and net may each be elongated tubular members having a selected cross-sectional configuration with each having longitudinal axes. The cross-sectional configuration of the support pole and net pole may, independently be selected from the group consisting of circular, elliptical, rectangular, triangular, and hexagonal configurations.
The bracket is operative to permit selected relative orientation of the net pole at selected locations longitudinally along the support pole. The bracket also, or in the alternative, be operative to permit selected angular orientation of the net pole with respect to the support pole.
In one embodiment, the bracket may include at least one sleeve portion adapted to slideably receive either the support pole or the net pole as a received pole. The sleeve portion has a sidewall formed in a generally C-shaped cross-section of a selected effective cross-sectional dimension. The bracket may further be provided with a flange projecting from longitudinally extending edges of the sidewall in facing relation to one another. As such, the fastener is operative to advance the flanges toward one another thereby to reduce the effective cross-sectional dimension thereof.
In another embodiment the bracket includes a first sleeve portion having a first sidewall that is adapted to slideably receive the support pole and a second sleeve portion having a second sidewall that is adapted to slideably receive the net pole. Each of the first and second sidewalls are formed in a generally C-shaped cross-section with an effective cross-sectional dimension. Here, the first sidewall includes a pair of first flanges projecting from longitudinally extending edges thereof in facing relation to one another. The second sidewall includes a pair of second flanges projecting from longitudinally extending edges thereof in facing relation to one another. The first and second pairs of flanges engage one another and the fastener is operative to advance the flanges toward one another thereby to reduce the cross-sectional dimensions of said first and second sidewalls.
The bracket may include a pair of spaced-apart webs interconnecting respective longitudinal edges of the first and second sidewalls. Here, the fastner is operative to advance the webs toward one another thereby to reduce the cross-sectional dimensions of the first and second sidewalls.
In an alternative construction, the bracket may include first and second sleeve portions that are formed as collar. Each collar includes a lobe projecting from the collar, a pair of flanges projecting therefrom in spaced-apart relation to one another. Here, the fastener extends between the flanges and is operative to advance the flanges toward one another thereby to reduce the cross-sectional dimensions thereof. The lobes are pivotally connected to one another.
Another aspect of the disclosed embodiments is a sports net system that is adapted to be erected on a surface. The system generally includes a pair of support poles that are each adapted to be positioned in an upright manner relative to the surface in spaced relation to one another. The system also includes a pair of net poles. First and second brackets may interconnect one of the support poles to one of the net poles thereby forming first and second pole pairs. As described above, the brackets are operative to permit the net poles to be oriented relative to a respected one of the support poles, the bracket having a selected construction, for example, as described above.
Another aspect of the disclosed embodiments is a method of positioning a net above a support surface. Aspects of the method include, in any order, erecting first and second support poles in an upright orientation on the support surface in spaced-apart relation to one another, securing a first edge portion of the net to a first net pole and securing a second edge portion of the net to a second net pole. The method includes interconnecting a first one of the support poles and a first one of the net poles as a first pole pair in a manner so as to permit them to be oriented with respect to one another at selected relative orientations and interconnecting a second one of the support poles and second one of the net poles as a second pole pair in a manner to permit them to be oriented with respect to one another at a selected relative orientation. The method may further include the step of securing each the first and second pole pairs in their respective relative orientations, which may particularly be a generally longitudinal orientation. The orientation of the first and second net poles may be a selected angular orientation relative to a respective one of the support poles so as to achieve a general uniform tension across the net.
The disclosed embodiments broadly relate to net support systems, but more particularly concern an adjustable sports net system that facilitates and simplifies that task of positioning and tensioning a sports net, such as a volleyball net. The embodiments shown herein are particularly directed to an adjustable net support system wherein an edge portion of the net can be raised or lowered with respect to the support poles to attain a desired height above a support surface. The embodiments herein also disclose a net support system that adjusts to provide a uniform tension in the net such as if the net is supported by more than one support pole. The present invention is further directed to a method of positioning a net above a support surface for court games that require a net as part of the game whereby the net may be placed at a selected game playing height and whereby the net support system adjusts to produce a uniform tension across the net.
One aspect of the adjustable net system disclosed herein is a pair of support poles that are supported by the playing surface. The poles may be permanently mounted to the playing surface or may be portable and attached by pushing them into the ground or by attaching them to a heavy base structure. The poles may also be provided rigidity and support by guy lines. The support poles may also be of an expandable type so that they can be stored compactly when not in use. Another aspect of the disclosed embodiments also includes a pair of net poles, to which an edge portion of either side of a net are attached, and a bracket that attaches each net pole to a support pole in a respective pole pair. The bracket is configured such that, when in a released state, the poles can be inserted into or removed from the bracket and the net pole can slide along the support pole for vertical positioning of the net and can be rotated with respect to the support pole for equalizing the tension in the net. In the clamped state, the bracket grips both the net pole and support pole and prevents their inadvertent movement.
With reference to
A detailed view of a portion of the adjustable net support system is shown in
Support pole 14 and net pole 16 may be of a variety of cross-sections including: hollow circular tubes, solid circular rods, hollow or solid rods of an elliptical, square, triangular, hexagonal, or other multi-sided shapes. As shown here, support pole 15 and net pole 16 are elongated tubular members. The poles 14 and 16 may be constructed of any material with sufficient rigidity to adequately support the net 12 during game play. Still referring to
A first embodiment of bracket 18 is shown in
As seen in
The first sleeve portion 30 and second sleeve portion 32 are sized to easily and slideably receive the support pole 14 and net pole 16, respectively, when the net support system 10 is assembled for use and in addition to allow the longitudinal positioning of bracket 18 with respect to the poles 14 and 16. Tightening the nut 36 and bolt 34 fastener squeezes or otherwise advances flanges 46 and 50 together thereby reducing the cross-sectional dimensions of said first and second sidewalls 42 and 25 thus clamping the first sleeve 30 and second sleeve 32 about the support pole 14 and net pole 16, respectively. The bracket 18 is constructed of an elastically resilient material with sufficient flexibility to deform when the fastener is tightened and thus clamp onto the poles 14 and 16. Such suitable materials for the bracket 18 include plastics and metals while aluminum is a preferable material.
Although the embodiment of the sports net system 10 shown in
The use of a single fastener to connect the first sleeve portion 30 and second sleeve portion 32 allows for the relative rotation of the two pieces as an adjustment feature.
As also mentioned, another desirable adjustment feature is the ability to position bracket 18 along the poles 14 and 16. As
