Abstract
A volleyball practice system that includes a generally rectangular first flexible panel supported from a pair of vertical supports, and at least one connector of adjustable length extending from at least one of the lower opposing corners of the first flexible panel. A second flexible panel that is smaller than the first flexible panel is supported in a generally parallel fashion from the first flexible panel. The first flexible panel extends below the second flexible panel, so that a trough area is created below the lower edge of the volleyball net when at least one of the lower opposing corners is suppported from the vertical supports.
Description




BACKGROUND OF THE INVENTION




(a) Field of the Invention




This invention generally relates to a volleyball or ball catching system. More particularly, but not by way of limitation, to a volleyball practice system that can be configured in various forms, such as to catch and return, hold, and drop a ball tossed against the system by a user.




(b) Discussion of Known Art




U.S. Pat. No. 5,827,137, incorporated herein in its entirety by reference, describes a portable volleyball practice apparatus. This practice apparatus includes a surface, such as a net, for catching a volleyball that is sent over a standard volleyball net or marker indicating the proper threshold for clearing a volleyball net. The surface impedes the flight of the ball and allows the ball to fall down near the net.




There remains a need for a device that allows the use of the catching net as a return mechanism, where the catching net accepts and allows the ball to roll back to the person hitting the ball. Also, there remains a need for a mechanism that allows a user to take a device such as my Portable Volleyball Practice Apparatus and quickly and inexpensively modify the device to achieve new and useful results, some of which have been described below. It will be understood that the disclosed invention allows the conversion of ordinary nets that are used for-catching into multi-functional net systems which have the capability to quickly convert from one configuration to another.




SUMMARY




It has been discovered that the problems left unanswered by known systems are solved by providing a set of connectors to a device, such as the device described in my U.S. Pat. No. 5,827,137. The connectors allow stretching and positioning of a catching component to achieve various functions. Preferably, the catching component will be a net or similar flexible sheet-like section with an upper border and a lower border. The disclosed connectors will be positioned on the lower border, and most preferably near a pair of lower corners of the catching component. The connectors will allow the catching component or net to cooperate with the volleyball net, or other component used to simulate a volleyball net to configure the catching component as a catch-and-hold device for catching and holding a ball. Also, the connectors will allow the catching component to be configured as a catch-and-return device that catches and directs the ball to roll back in a desired direction. Other configurations include functions as a target-rebound device and a catch and drop device.




It should also be understood that while the above and other advantages and results of the present invention will become apparent to those skilled in the art from the following detailed description and accompanying drawings, showing the contemplated novel construction, combinations and elements as herein described, and more particularly defined by the appended claims, it should be clearly understood that changes in the precise embodiments of the herein disclosed invention are meant to be included within the scope of the claims, except insofar as they may be precluded by the prior art.




The accompanying figures show how to use disclosed components of the invention, including the use of a large net, or first flexible panel, capable of extending above and below a standard net or truncated volleyball net, or second flexible panel, and the unique attachments for changing configurations.




Catch and Hold Configuration




This configuration is achieved by connecting the lower opposing corners to the quick release link to stretch the first flexible panel-lower edge taut. This will form a fold or pouch or trough in the first flexible panel. The first flexible panel shall be behind the lower net with respect to the hitter. The hitter hits the ball into the first flexible panel and the ball will be directed down between the two nets and fall into the pouch and remain there.




Catch & Return Configuration




This configuration is achieved by supporting the lower opposing corners of the first flexible panel with a specific slackness. The upper net shall be behind the lower net with respect to the hitter. The hitter hits the ball into the upper net and the ball will be directed down between the two nets. The upper net redirects the downward momentum of the ball and returns the ball to the hitter.




Catch and Drop Configuration




This configuration is similar to the Catch & Return configuration, except that one or both of the lower opposing corners are disconnected and the ball will fall freely below and behind the nets.




Target Rebound Configuration




This configuration is achieved by using the first flexible panel as a backing panel behind the second flexible panel. The hitter hits the ball into the upper net and the ball rebounds directly back.




It should also be understood that while the above and other advantages and results of the present invention will become apparent to those skilled in the art from the following detailed description and accompanying drawings, showing the contemplated novel construction, combinations and elements as herein described, and more particularly defined by the appended claims, it should be clearly understood that changes in the precise embodiments of the herein disclosed invention are meant to be included within the scope of the claims, except insofar as they may be precluded by the prior art.

DETAILED DESCRIPTION OF PREFERRED EXEMPLAR EMBODIMENTS




While the invention will be described and disclosed here in connection with certain preferred embodiments, the description is not intended to limit the invention to the specific embodiments shown and described here, but rather the invention is intended to cover all alternative embodiments and modifications that fall within the spirit and scope of the invention as defined by the claims included herein as well as any equivalents of the disclosed and claimed invention.




Turning now to

FIG. 1

where a volleyball practice system


10


has been illustrated mounted between a pair of vertical supports


12


. The example illustrated in

FIG. 1

includes a first flexible panel


14


that includes a pair of upper opposing corners


16


and a pair of lower opposing corners


18


. The pair of lower opposing corners


18


are at a first distance


20


from the upper opposing corners


16


. The pair of upper opposing corners


16


have been shown while being supported from the pair of vertical supports


12


.




Turning now to

FIGS. 2 and 3

, it will be understood that at least one connector of adjustable length


22


will be attached to at least one of the lower opposing corners


18


of the first flexible panel


14


. The length adjustment function of the connector of adjustable length


22


in the illustrated example is carried out by providing a first tether line


24


of a length


26


and a second tether line


28


of a length


30


. The length


26


of first tether line


24


being greater, or longer, than the length


30


of the second tether line


28


. The first tether line


24


and the second tether line


28


include a loop


32


, ring, or other mechanism that cooperates with a quick release connector


34


, such as a carabiner a snap hook, hook with a spring loaded gate, or other connector. The quick release connector


34


may be attached to a lower tension line


36


, a volleyball net, or the vertical supports


12


. Thus the connection of the first tether line


24


or the second tether line


28


to the quick release connector will vary the support geometry on the corresponding lower opposing corner


18


. Thus, by attaching the second tether


28


to the quick release connector


34


one creates a trough


38


with a pronounced sidewall, meaning that the lower edge


40


of the first flexible panel


14


will be drawn taut and up, as indicated by the arrow


42


.




By creating a high, taut, lower edge


40


on the trough


38


, the disclosed invention can be used to catch and hold a ball


44


that strikes the first flexible panel


14


, either by traveling over the upper edge


46


of a volleyball net


48


that may be used with the system


10


, or under the lower edge


50


of the volleyball net


48


. It is important to note that while it is contemplated that the disclosed system may cooperate with a volleyball net


48


, it is also contemplated that the system may incorporate a second flexible panel


52


that is supported from the vertical supports


12


, in a generally parallel manner at a distance from the first flexible panel


14


.




When both panels are used, as illustrated in

FIG. 1

, it is contemplated that the second flexible panel


52


will include an upper edge


54


and a lower edge


56


that is approximately parallel to the upper edge


54


and at a second distance


58


or height from the upper edge


54


. Additionally, the second flexible panel


52


will be supported at a panel distance


60


from the first flexible panel


14


.




It is important to note that whether the system is used in conjunction with the second flexible panel


52


or with a volleyball net


48


, the second distance


58


, which is the vertical depth or height of the second flexible panel


52


material or the vertical depth or height of the volleyball net


48


material should be smaller than the first distance


20


of the first flexible panel


14


. It is contemplated that the first flexible panel


14


material will be longer in a vertical direction than the second flexible panel


52


or the volleyball net in order to allow the lower edge


40


of the first flexible panel


14


to be curled up to form the trough area


38


created below the lower edge


50


of the volleyball net


48


or the lower edge


56


of the second flexible panel


52


when at least one of the lower opposing corners


18


is supported directly or indirectly from the vertical supports


12


.




It is important note that by varying the degree of the curling up of the lower extremities of the first flexible panel


14


allows the user to form the trough


38


area, which allows the disclosed invention to produce important new and useful results. For example by using the first


13


tether instead of the second tether line


28


to support the lower opposing corners


18


directly or indirectly from the vertical supports


12


, one can create a shallower trough area, with the lower edge


40


of the first flexible panel


14


held in a relatively slack manner. With this arrangement a ball


44


that is captured by the first flexible panel


4


will roll out of the trough


38


in the general direction of the person who drove the ball into the first flexible panel


14


. This arrangement has been illustrated in

FIGS. 7



d


and


8


.




Thus, as shown on

FIGS. 1

,


4


,


5


and


7




a


-


7




d


, it is contemplated that the second flexible panel


52


will extend along a second panel plane


64


, and the pair of upper opposing corners


16


of the first flexible panel


14


lie along a first flexible panel upper edge line


66


, the first flexible panel upper edge line


66


being positioned in a generally parallel manner to the second panel plane


64


.




Also illustrated in

FIGS. 1

,


2


, and


4


-


6


is that it is further contemplated that the disclosed system will include a tension connector


70


that is attached to the first flexible panel


14


at a location between one of the pair of upper opposing corners


16


and the lower opposing corner directly below the one of the pair of upper opposing corners


16


. The tension connector


70


may be adapted for attachment to the lower edge


50


of the volleyball net


48


to provide tension to the first flexible panel


14


between the tension connector


70


and the pair of upper opposing corners


16


. This will reinforce or back-up the volleyball net


48


or second flexible panel


52


, as illustrated in

FIG. 1

, so that a ball that is driven against these surfaces rebounds with a great proportion of the energy carried into the net or flexible panels.




Thus, in light of the above discussion, it will be understood that the first flexible panel


14


may be of a first panel width


72


and said second flexible panel


52


may be of a second panel width


74


, with the first panel width


72


being approximate equal to the second panel width


74


.




Still further it is contemplated that the first connector of adjustable length


22


may be a strap with a cinching or reeling mechanism that allows the strap to be lengthened or shortened to vary the depth and rigid y the trough


38


area. When using two tethers for the first connector of adjustable length, it is contemplated that one or both of the tethers may be of an elastic material that will stretch to allow access into the trough in order to retrieve the balls. Additionally, it is contemplated that this will allow tightening of one of the lower opposing corners


18


versus the other opposing corner


18


on the first flexible panel


14


. This would direct the ball


44


to roll out of the trough


38


in the direction of the opposing corner


18


that is supported loosely, if supported at all.




It should be understood that it is contemplated that the disclosed invention may be configured to catch a volleyball, catch and return a volleyball, provide a backing or bouncing surface for target practice with a volleyball, or stop and drop a volleyball that is driven a volleyball net or a second flexible panel that simulates a volleyball net. Still further, it is contemplated that the vertical supports may be fixedly supported from the practice surface or supported from a portable support base that rests on the practice surface


62


.




Thus it can be appreciated that the above described embodiments are illustrative of just a few of the numerous variations of arrangements of the disclosed elements used to carry out the disclosed invention. Moreover, while the invention has been particularly shown, described and illustrated in detail with reference to preferred embodiments and modifications thereof, it should be understood that the foregoing and other modifications are exemplary only, and that equivalent changes in form and detail may be made without departing from the true spirit and scope of the invention as claimed, except as precluded by the prior art.
