This invention relates to tennis court nets, in general, in general, and to an advanced, improved headband for extension along the top of a tennis court net, in particular.
As will be appreciated, the tennis court net is the single most important structure in tennis play, splitting the court into two equal halves. The net, forming a criss-cross pattern is the main obstacle in the game, and hitting the ball over the net is the cardinal rule of tennis. Suspended by net posts, the small square holes which define the net must be tiny enough so that the tennis ball cannot pass through the net, and the net must touch the ground so that the ball cannot travel under it. Being held down in the center by a white strap, the net also must have a cord or metal cable running along its top—which in accordance with tennis rules, must be covered by a white band.
Recognizing that a player's skill, quickness and power means nothing if he/she cannot properly land the tennis ball over the net and into the opponent's court, experience has shown that one of the problem areas is that the white band creates a “blind spot” through which the player is unable to see, in determining whether the ball struck properly lands in or out. In such circumstances, the player needs to rely on the opposing player's honesty in calling the shot as good or bad. Such “blind spot” follows from the white band (termed a “headband”) being a nontransparent vinyl or fabric running along the top of the tennis court net, extending down on both its sides some 2½ inches.
It is an object of the present invention, therefore, to provide an advanced and improved headband of this type in which the resultant “blind spot” is reduced, no matter where, on the court, the player hitting the ball may be located—in forecourt or at the base line.
It is another object of the invention to provide such a headband which can be easily replaced over time as the headband wears, or is tow in play.
It is a further object of the invention to provide such a headband for use whether the tennis court net is employed in indoor or outdoor play.
As will become clear from the following description, the headband of the invention will be seen to comprise a first length of nontransparent material and a second length of transparent material. Means are provided for coupling the transparent material with the nontransparent material so that the transparent material extends downwardly below the nontransparent material at least 100%-150% greater than the width of the nontransparent material. Means are also provided for coupling a bottom edge of the of transparent material along the top of the tennis court net.
In a first embodiment, a headband for extension along the top of a tennis court net in accordance with the invention includes a length of a nontransparent vinyl band having a top edge, a bottom edge, and a first width between them—and, a length of transparent vinyl film having a top edge, a bottom edge, and a second width between them greater than the first width. Means are included for joining the nontransparent band over the transparent film so that the greater width of the transparent film hangs down over both sides of the tennis court net. As described below, the transparent film is selected of a 5″ width to drape some 2-2½″ on each side of the net, the nontransparent band is selected of a 2″ width, and 1½″ visual overlay essentially results—150% greater than the width of the nontransparent vinyl band.
In a second embodiment of the invention for coupling to and along the top of the tennis court net, a length of transparent clear vinyl film is included as having a first top edge to bottom edge width, and a length of nontransparent vinyl or fabric band having a second lesser top edge to bottom edge width. Means, here, secure the nontransparent band equally spaced between the top edge and bottom edge of the transparent clear vinyl film, with the securement being such that folding the top edge of the transparent clear vinyl film over to the bottom edge of such material results in a lapping of the transparent clear vinyl film over the nontransparent band on both the top and the bottom. A 5″ width for the transparent film is selected, along with a 2″ wide band for the nontransparent material, so that the extent of visual overlay again is essentially 1½″, 150% greater than the width of the nontransparent band.
Different arrangements can be used for securing the headband along the top of the tennis court net so as to have the headband replaceable or not, and also to enable the headband to be used indoors or outdoors—with an outdoors use being one where the transparent vinyl film could be selected to be glare resistant, ultraviolet resistant and/or fungal resistant as well.
These and other features of the present invention will be more clearly understood from the following description, in which:
In
In further accordance with these association rules, the headband 22 (from its top edge 30 to its bottom edge 32) is 2″ to 2½″ wide, extending along the top of the net 10. Experience has shown, however, that such width—whether composed of a white vinyl band or fabric or otherwise—creates a “blind spot” for players on each side of the net to determine whether the ball struck in play properly lands in or out of the court's field. In accordance with the present invention, on the other hand, the headband is of a different configuration and manner, so as to reduce such “blind spot” effect.
More specifically—in the first embodiment of
In satisfying an objective of the invention to reduce the extent of the “blind spot” with a clear polyvinyl for the transparent vinyl film 44 and a nontransparent vinyl for the band 42 and to comply with tennis association rules, the width 54 of the nontransparent vinyl 42 is selected to be 2″, while the greater width 56 of the clear polyvinyl 44 is selected to be 5″. (In a preferred construction, the nontransparent vinyl band is colored “white”, the transparent polyvinyl film 44 is stitched to the netting 12 by a black filament, and the nontransparent band 42 is stitched to the transparent film 44 by a clear or white filament. At the same time, either by decreasing the width of the nontransparent vinyl material, or increasing the width of the transparent clear material, the ratio of the widths between the two will be able to reduce the extent of the “blind spot”, even more, i.e. by increasing the downward extension of the transparent material even more than the 100%-150% above relationship.)
For the folded over in half 2½″ headband, a see-through width of some 1½″ results below a 1″ or so “white” visual marker for the net 10—with the respective widths being correspondingly reduced if the overall headband were to be manufactured of lesser width, or increased if the overall headband were to be manufactured of greater width. (While the folding over of the nontransparent and transparent materials 42, 44 cause a degree of “roundness” which prevents an exact 1½″ see-through dimension forming, it allows for the insertion of a 0.3″ diameter cord or metal cable between them for an added rigidity to the headband format. As such, when folded over, the transparent material extends substantially only some 100%-150% more than the width of the nontransparent band.)
Usable with a tennis court net for either indoor or outdoor play, and in accordance with the invention, the transparent polyvinyl film 44 can be composed of a glare resistant material, with or without ultraviolet resistance fabrication, and with or without a plurality of weep hole slits 60 spaced along the transparent polyvinyl film 44 for draining any condensate that may collect within the polyvinyl film 44 during tennis play in a heated, humid, or wet environment. Similarly, a “snapping” securement between the transparent polyvinyl film 44 and the nontransparent vinyl band 42 could be utilized instead of a “stitching” securement as described above.
As an alternative to stitching the nontransparent vinyl band 42 to the transparent vinyl film 44 when draped over it in folding both in half from top to bottom, the embodiment of the invention shown in
Recognizing that headbands may wear or tear over time, the present invention also affords a manner of coupling them to the net other than by a conventional stitching—and thereafter replacing them. Similarly, an employment of snaps or hooks adjacent to the bottom edge of the headband can then be utilized to join at the top of the netting with similar manners of attachment. Such hooks or snaps are illustrated at 83, 85 in
While there have been described what are considered to be preferred embodiments of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. Thus, for example, while equal lengths of the nontransparent material and transparent material are preferable in construction, differing lengths may be used instead as long as the relationship in width is maintained—whether between 100%-150% or more. So, too, other nontransparent and transparent materials may be employed to provide similar advantageous effects as well. And as will be apparent, for thicker gauge vinyls or other materials utilized, the widths of the nontransparent materials may well need to be increased beyond the indicated sizes of 2″ and 5″ respectively, especially for greater diameter cords or metal cables used to provide rigidity to the headband.
For at least such reasons, therefore, resort should be had to the appended claims for a true understanding of the invention.
