5 Claims, 3 Drawing Figures PATENTEDJAH 15 I975 SHEET 1 [IF 2 INVENTOR BALL REBOUNDING MEANS BACKGROUND OF THE INVENTION This invention relates to a recreational apparatus for rebounding balls or similar objects. More particularly, this invention includes means for supporting a net means in tension whereby a ball or similar object brought into engagement there against will be returned in the general direction from which it arrived.
In order for a thrower, such as a baseball player, to practice throwing, it is generally necessary to provide a catcher who can receive and return the ball. In the past, in some, instances, a thrower would throw the ball against a wall which would serve as a back stop and may possibly return the ball in the general direction from which it was thrown. However, the latter possibility is not always feasible, particularly if the ball is con structed of a nonresilient material such as a baseball. Furthermore, obviously, such walls are not always available for throwing practice. In addition, the throwing of a baseball against a solid wall could result in damage to both the baseball and to the wall if the wall was not specifically designed for having objects thrown there against.
There have been a number of patents issued disclosing a frame means for supporting a net under tension whereby a ball or similar object thrown against the net will be rebounded in the direction from which it is thrown.
The US. Pat. to Dixon, No. 2,944,816, issued July 12, 1960 discloses such an apparatus which includes a support frame for supporting a net under tension to be used for rebounding a baseball or similar object in the direction from which it was thrown. One disadvantage with the apparatus disclosed in the patent to Dixon resides in the fact that after a continued period of use of the net, the tension of the net will become loose, usually to the point that the net will no longer return the ball to the thrower. At still other times, it is desired to vary the tension on the net whereby the net will return the ball a more or less predetermined distance. The only means for adjusting the tension on the Dixon apparatus is by increasing or decreasing the number of elastic attachment elements by which the net is attached to the frame means, and such an adjusting means would be difficult to effect, increasing the cost, and unreliable in the degree of adjustment.
In certain other recreational sports utilizing a ball, a hand controlled racket means is used to rebound a ball in a desired direction. The prior art hand controlled racketrmeans are complex in design and expensive to manufacture.
' SUNIMARY OF THE INVENTION It is therefore a primary object of this invention to provide an apparatus for rebounding balls or similar objects brought into engagement therewith.
A further object of this invention is to provide an apparatus for rebounding balls or similar objects wherein the apparatus includes a net secured under tension with means for varying the tension on the net.
Another object of this invention is to provide an improved, and more accurate rebounding of balls, or similar objects, thrown into engagement there against.
Yet another object of this invention is to provide an improved hand controlled racket for rebounding balls or similar objects in a desired direction.
A still further object of this invention is to provide an apparatus for rebounding balls or similar objects which is readily assembled and disassembled, portable and lightweight in construction.
Still another object of this invention is to provide a means for securing a net under tension to a supporting frame means, with means for adjusting the tension on the net.
An additional object of this invention is to provide an apparatus for rebounding balls or similar objects which is simple in construction, economical to manufacture and reliable in performance.
The above stated objects are obtained and the disadvantages of the prior art are overcome by the present invention which basically includes a tubular frame means formed and connected together to form a substantially rectangular frame support. A net is secured under tension within the frame means for rebounding a ball or similar object brought into engagement there against. A number of attachment elements are secured to the frame means at selectively spaced locations. An important feature of the present invention resides in the utilization of a predetermined length of nylon cord which is interlaced within the net adjacent the border thereof and wherein the nylon cord is secured to the attachment elements to hold the net under tension within the frame means. The predetermined length of nylon cord includes opposite end portions which are selectively secured together in a number of set positions whereby the tension on the net can be varied. One embodiment of the present invention provides a number of leg means attached to the rectangular frame support for maintaining the supported net in a generally upright position. An alternate embodiment of the present invention provides a hand controlled handle means attached to a rectangular frame to allow the supported net to be maneuvered by hand to rebound a ball in a desired direction.
Still other objects and advantages of the details of construction will become apparent upon reading the following description of the illustrative embodiments of the invention with reference to the attached drawings wherein like reference numerals have been used to refer to like parts throughout the several figures of drawing, and wherein:

The U-shaped frame members 11, 12 are connected together by a pair of elongated tubular elements 13, 14 which include reduced end portions 15 (FIG. 2) that are inserted in the extended ends of the legs of the U-shaped frame members 11, 12. The supporting frame means 10 is held in a substantially upright position by a pair of rearwardly inclined leg members 16, 17 which are secured adjacent their upper end by a connecting bolt means 18, to the elongated tubular elements 13, 14. A pair of brace members 19, 20 are secured to an intermediate portion of the leg members 16, 17, respectively, with conventional bolt connecting means 21. The opposite ends of brace members 19, 20 are secured to the elongated tubular elements 13, 14 at a position spaced below the connection of the upper connected end of legs l6, l7. Brace members 19, 20 are connected to the elongated tubular members 13, 14 by conventional connecting bolts 22.
The support frame elements 11-14 and leg structure 16, 17 are constructed of conventional metal stock material. The telescoping connection of the elongated elements 13, 14 within the legs of the U-shaped members 11, 12 are detailed such that the elongated members 13, 14 with the connected legs 16, 17 can be rotated relative to the U-shaped supporting members whereby the legs can be moved from a rearwardly extending position, shown in FIG. 1 to a position lying against the rear of the net whereby the apparatus can be conveniently stored in a reduced area when not in use.
Referring now particularly to FIG. 2, the net member is constructed of a plurality of vertical thread members 26, a plurality of horizontal thread members 27 connected together by conventional means in spaced apart relationship to form a series of substantially rectangular openings therebetween. The extended ends of threads 26, 27 are connected to a border member 28 which extends around the peripheral edge of net 25. Net 25 is constructed of a nylon material to provide the required strength and resiliency for rebounding a ball or similar object thrown into engagement therewith. However, the net 25 could be constructed of still other suitable material which would provide the required strength and resilient characteristics.
As shown in FIG. 2, the net is connected to the supporting frame by a plurality of attachment elements 30 which are secured to the tubular frame members in spaced apart relationship around the border of the net 25.

The alternative embodiment includes length of material bent to form outwardly directing support leg members 41, 42. Leg member 41, 42 extend outwardly from the generally rectangular frame in substantially parallel relationship to each other and are supported by complementary socket receiving means 43, 44 formed on a handle support member 45. Legs 41, 42 are maintained in a locked position within sockets 43, 44 by means of conventional connecting bolts 46, 47, which are inserted through complementary openings formed in the sockets 43, 44 and legs 41, 42. An extended end of handle support member 45 is provided with an end cap member 48. Cap member 48 is constructed of a rubber or synthetic material which will allow the outer end of handle 45 to be sealed.
As shown in FIG. 3, a net member 50 is supported under tension in substantially coplanar relationship with frame member 40. Net 50 is constructed of a number of parallel arranged thread members 51 which are connected by conventional means to a number of parallel arranged thread members 52. Thread members 52 are connected to thread members 51 in substantially right angular relationship to form a number of squareshaped openings between adjacent thread members 51, 52. Net 50 is provided with a border member 53 connected to the extended ends of threads 51, 52. Net 50 can be constructed of a nylon material or a similar synthetic material which will provide the required strength and flexibility characteristics.
OPERATION After the framework has been properly assembled, the
net 50 is connected thereto by inserting two of the S- shaped clips 49 in each of the four corners of the net and connecting the S-shaped clips to the framework 40.
After the net 50 has been connected with the pair of clips in each corner, additional connecting means is provided by interlacing the nylon cord 55 within thread members 51, 52 adjacent border 53 and connecting the cord 55 to each of the S-shaped clips 49.

However, other types of metal stock material or synthetic material could be utilized which would provide the required rigid characteristics with lightweight construction. The configuration of frame member 40 will include rectangular, round and oval shapes.
It now becomes apparent that the above described illustrative embodiment is capable of obtaining the above stated objects and advantages. It is obvious that those skilled in the art may make modifications in the details of construction without departing from the spirit of the invention which is to be limited only by the scope of the appended claims.
What is claimed is:
1. An apparatus for rebounding balls or similar objects brought into engagement therewith comprising a generally rectangular frame, supporting means adjacent each corner of said frame, additional supporting means on each side of said frame intermediate the corners thereof, a net having a shape corresponding to but slightly smaller than that of said frame, said net being supportingly engaged adjacent each corner by said supporting means but being free of engagement by said intermediate supporting means, and means for adjusting the tension of said net with respect to said frame means comprising an elongated member slidably passing through each of said supporting means and interlaced with the outer marginal portion of said net between each two corners, the ends of said elongated member being adjustably secured together, whereby tightening of said elongated member will tend to straighten the edges of the net between the corners thereof and to increase the tension around the border of the net.
2. An apparatus as in claim 1 wherein said elongated member is a nylon cord.
3. An apparatus as in claim 2 wherein the ends of said cord are secured together by a releasable connecting knot.
wherein inclined leg members are secured to said elongated tubular members, whereby rotation of said lastmentioned members in their engagement with the legs of the U-shaped sections will permit the legs to be placed flat against said net or extended outwardly therefrom into frame-supporting position.
