Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims benefit of pending provisional application U.S. 61/990,041 filed May 7, 2014, which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

Tennis is a very popular sport. But tennis clubs are expensive, and there are not many environments with the requisite facilities for someone to practice at will. It is desirable to have available a portable apparatus and related method which enables a person to practice tennis, alone, in any environment, with minimal noise, in limited space, at will.

SUMMARY OF THE INVENTION

Solo play™ is a portable, adjustable, lightweight, silent tennis backboard substitute, and is in the nature of a vertically-oriented trampoline for the tennis ball. It is like practicing with a silent opponent.
The mesh trampoline can be fabricated in different sizes from 4-8 feet long by 3-7 feet high, or more. The mesh may be a polyester or other similar material.
The device has a telescopic frame. The frame may be adjusted to increase or decrease the tension of the screen mesh so the tennis balls can be rebounded faster or slower. No matter how hard one hits the ball, whether soft or hard, the trampoline is quiet when the ball strikes. The ball bounces off from 3 to 5 feet from the apparatus, depending on the mesh tension. The more the tension, the further the ball bounces back. For a given tension, each rebound is at substantially the same rate.
The apparatus is excellent for practicing tennis strokes, top spin, timing, and hand-eye and ball coordination.
The invention disclosed is a portable apparatus and related method for practicing tennis, comprising: a frame substantially fixed in a substantially vertical orientation; and a mesh mounted to the frame, disposed in a substantially vertical plane, and pulled taut in relation to the frame to a user-determined tension; wherein: the structural combination of the frame, the mesh and the tension of the mesh in relation to the frame enables a tennis ball striking against the mesh to rebound from the mesh in the manner of a trampoline rebound; whereby: a user of the apparatus can practice tennis, alone, in any environment, with minimal noise, by hitting the tennis ball into the mesh, and thereafter successively hitting rebounds from the mesh back into the mesh, at will. This enables a person to practice tennis, alone, in any environment, with minimal noise, at will.

DETAILED DESCRIPTION

The drawings contain some photos of the solo play tennis practice apparatus, collapsed and expanded, and in use, as developed for experimental testing. This is an exemplary embodiment, and should not be regarded as limiting in any way.

FIG. 6 shows the fully assembled apparatus with the mesh pulled taut, and a tennis ball about the strike the apparatus.
FIG. 7 shows the fully assembled apparatus with the mesh pulled taut while in use. The tennis ball has just struck and started to rebound from the trampoline mesh.
FIG. 8 shows a close-up view of an exemplary device use to connect two sections of framing.
FIG. 9 shows a close-up view of an upper corner of the assembled framing.
FIG. 10 shows a close-up view of a lower corner of the assembled framing.
Although the framing in the photos is shown to be straight, a parabolic or other conic or other curved framing can be used to create a convex curvature for the mesh. In this configuration, no matter what the angle at which the ball strikes the screen mesh, the ball will rebound right back to the locale ate which the player is standing. The overall framing as viewed from the user's perspective may be square, rectangular, round, or any other suitable shape. The framing and attached mesh are substantially vertical, though embodiments with a mild tilt away from the user (so as to lift the ball slightly upon rebound) are envisioned within the scope of the disclosure and associated claims.
In an alternative embodiment of the invention illustrated in FIGS. 11 and 12, the framing can be designed with angled peripheral sections 3 to cause additional inward angling of the mesh near the edges of the mesh. One way to embody this is to employ both an outer frame 1 and an inner frame 2, with each frame having a periphery, with the outer frame spanning 360 degrees and the inner frame spanning all or a portion of 360 degrees, with the outer frame periphery enclosing the inner frame periphery as viewed by the user as seen in FIG. 11, and with the inner frame periphery being fixed behind the outer frame periphery, i.e., with the inner frame further from the user than the outer frame, also as viewed by the user.
So the bottom of the mesh would be angled upwards, the sides of the mesh would be angled inwards, and the top of the mesh would be angled downwards, all while the central area of the mesh remains substantially perpendicular to the location of the person using the device. Some or all of the top, bottom and side mesh regions may be angled in this fashion. Thus, a ball hitting along the edges 3 would not merely reflect, but would be redirected. Sometimes the mesh returns the ball in the form of an overhead shot, and this configuration also adds spin to some of the returns from the mesh. This variation adds versatility and enhances the user experience because just as in a regular game of tennis, the ball is not returned by the opponent in the same way every time, but is returned in a variety of unpredictable ways which are at the heart of what makes tennis an interesting and challenging game. Also, if the edges of the mesh cause the ball to be redirected on the return, this would implicitly tell the user that the user did not hit the center of the mesh, but hit one of the edges, thus helping the user adjust the precision of his or her shots. As with the illustrated embodiments, this can all be adjusted to bounce the ball faster or slower by adjusting the screen tension.
FIG. 13 illustrates yet another alternative embodiment, now with an upwardly-angled peripheral section along the upper edge of the mesh. Similarly to the inwardly-angled mesh sections shown in FIGS. 11 and 12, a tennis ball striking this upwardly-angled section will rebound differently than a tennis ball striking the central area of the mesh. Here, the tennis ball will rebound with greater loft (height) than a tennis ball striking the central area of the mesh. This, of course, simulates a high tennis return from an opponent.
It will also be observed at the very highest portion of the mesh in FIG. 13, the mesh is mounted over a top horizontal mesh-support bar, and then curls downward as one moves to the back of the framing. There are two aspects to this configuration which are important to appreciate. First, there are several mounting positions along the top horizontally-disposed bars of the framing between which horizontal mesh-support bar is perpendicularly-disposed. By the user mounting the mesh-support bar further toward the rear of the framing, the loft of a tennis ball striking the upwardly-angled section will be increased. Thus, the user is given control to adjust this loft angle at will.
Second, it will be observed that the rear, lowest extremum of the downward-curling mesh is also mounted to a back section of the framing. By lowering or raising the position of this lower-extremum frame mounting, the tension of the overall mesh is either increased or decreased, consequently yielding a longer or shorter rebound.
In general, it is desirable for the user to be able to adjust the mesh tension in order to control the mean rebound distance of the tennis ball. This particular way of controlling the mean rebound distance shown in FIG. 13 is intended to be exemplary, not limiting. Others of ordinary skill in the art will be able to develop equivalent ways of making this adjustment toward the same end, within the scope of this disclosure and its associated claims. What is generally disclosed by this aspect of FIG. 13 is having at least two different ways in which the mesh can be mounted to the frame by the user, at will, wherein the selection of each particular way of mounting the mesh to the frame varies the tension of the mesh relative to other ways of mounting the mesh to the frame, whereby the user is enabled to control a mean rebound distance of the tennis ball.
The disclosures of FIGS. 11, 12 and 13 will make clear that in general, whether inwardly- or outwardly-angled, the presence of at least one differently-angled peripheral mesh section along an edge of the mesh in relation to the central area of the mesh will cause variations in the direction at which the tennis ball rebounds toward the user depending upon where the tennis ball strikes the mesh, thereby simulating variable tennis returns from an opponent. In FIGS. 11 and 12 all four edges are inwardly-angled. In FIG. 13 the top section is upwardly angled to add loft. Combining such variable angling, and giving the user the ability to adjust this angling at will, in addition to giving the user the ability to adjust the mesh tension either globally or locally at will, provides an apparatus that can give a tennis aficionado many quiet hours of customized solo exercise and enjoyment in a limited space.
