Abstract
Abstract A rebound ball game in which a ball is returned between opposed players within a prescribed court divided by a rebound apparatus having rebound faces and a specified return area, the rebound faces being angled for rebound of the ball toward the respective players, and the return area being located above the rebound faces for defining the appropriate area through which the ball is to be passed between the opposed players, the court having limited trapezoidal playing areas at each side of the rebound apparatus.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
249 words
In a rebound ball game in which opposed players return a ball within a prescribed court extending along a horizontal playing surface in opposite longitudinal directions from a rebound apparatus located on the playing surface between the players such that the court is divided into first and second opposed playing areas with the rebound apparatus placed therebetween, the rebound apparatus comprising: first rebound means for placement laterally across the court to extend upwardly therefrom at an angle to the playing surface, the first rebound means including a first rebound face for confronting the first playing area and making an angle therewith such that upon reception of the ball from the first playing area the first rebound means will rebound the ball toward the first playing area; second rebound means for placement laterally across the court to extend upwardly therefrom at an angle to the playing surface, the second rebound means including a second rebound face for confronting the second playing area and making an angle therewith such that upon reception of the ball from the second playing area the second rebound means will rebound the ball toward the second playing area; and return area means between and extending upwardly above the first and second rebound means for defining an open, generally vertical return area of prescribed dimensions through which the ball is to be passed upon return of the ball from one of the first and second playing areas to the other of the first and second playing areas.
Claim 2
Dependent Claim

In a rebound ball game in which opposed players return a ball within a prescribed court extending along a horizontal playing surface in opposite longitudinal directions from a rebound apparatus located on the playing surface between the players such that the court is divided into first and second opposed playing areas with the rebound apparatus placed therebetween, the rebound apparatus comprising: first rebound means for placement laterally across the court to extend upwardly therefrom at an angle to the playing surface, the first rebound means including a first rebound face for confronting the first playing area and making an angle therewith such that upon reception of the ball from the first playing area the first rebound means will rebound the ball toward the first playing area; second rebound means for placement laterally across the court to extend upwardly therefrom at an angle to the playing surface, the second rebound means including a second rebound face for confronting the second playing area and making an angle therewith such that upon reception of the ball from the second playing area the second rebound means will rebound the ball toward the second playing area; and return area means between and extending upwardly above the first and second rebound means for defining an open, generally vertical return area of prescribed dimensions through which the ball is to be passed upon return of the ball from one of the first and second playing areas to the other of the first and second playing areas.
Claim 3
Dependent Claim
32 words
The invention of claim 1 wherein the angle between each of the first and second rebound faces and the corresponding one of the first and second playing areas is an obtuse angle.
Claim 4
Dependent Claim
129 words
The invention of claim 2 wherein the rebound apparatus includes a frame having: foot portions located in a basal plane for placement upon the playing surface; a first frame section extending upwardly from the basal plane at a first acute angle thereto for carrying the first rebound means; a second frame section extending upwardly from the basal plane at a second acute angle thereto for carrying the second rebound means; the first and second frame sections intersecting at an apex to establish a generally triangular profile with the basal plane defining the base of the triangular profile and the frame sections defining the sides of the triangular profile; and a third frame section extending generally vertically upwardly from the apex and establishing a fixed perimeter around the return area.
Claim 5
Dependent Claim
29 words
The invention of claim 3 wherein each rebound means includes a rebound net and the rebound apparatus includes tensioning means tensioning the rebound net within a corresponding frame section.
Claim 6
Dependent Claim
22 words
The invention of claim 4 wherein the first and second acute angles are equal and the triangular profile is an isosceles triangle.
Claim 7
Dependent Claim
110 words
The invention of claim 5 wherein: the foot portions are each located at a corner of a rectangle in the basal plane; the first frame section includes first leg members, each extending upwardly from a foot portion to the apex, and a first cross-member extending laterally between the first leg members intermediate the foot portions and the apex; the second frame section includes second leg members, each extending upwardly from a foot portion to the apex, and a second cross-member extending laterally between the second leg members intermediate the foot portions and the apex; and the frame includes a third cross-member having opposite ends and extending laterally along the apex.
Claim 8
Dependent Claim
35 words
The invention of claim 6 wherein the rebound net includes opposite ends, and each opposite end is secured to one of the first and second cross-members, with the rebound net passing over the third cross-member.
Claim 9
Dependent Claim
73 words
The invention of claim 6 wherein the third frame section includes a pair of upright members, one upright member extending vertically from the apex adjacent each end of the third cross-member, and a fourth cross-member extending laterally between the upright members generally parallel to the third cross-member and spaced vertically upwardly from the third cross-member to define a generally rectangular return area bounded by the third and fourth cross-members and the upright members.
Claim 10
Dependent Claim
43 words
The invention of claim 8 wherein each opposed playing area is trapezoidal and includes a base line opposite side lines extending from the rebound apparatus location to the base line, the base line being the longer of the bases of the trapezoidal configuration.
Claim 11
Dependent Claim
28 words
The invention of claim 9 including a service line extending across the court adjacent the rebound apparatus location and parallel to the base line in each playing area.
Claim 12
Dependent Claim
44 words
The invention of claim 1 wherein each opposed playing area is trapezoidal and includes a base line and opposite side lines extending from the rebound apparatus location to the base line, the base line being the longer of the bases of the trapezoidal configuration.
Claim 13
Dependent Claim
