Abstract

The specification discloses an apparatus and method for playing a game (10) on a playing surface with a tethered ball (28) and stringed racquets. The ball (28) is connected to one end of a resilient tether cord (24), which is anchored at the other end to the playing surface. A boundary line (54) of predetermined length is positioned on the playing surface in spaced apart relationship with the anchor point of the tether cord (24). The boundary line (54) divides the playing surface into a playing zone (56) wherein the players must remain during the game, and a bounce zone (58). The ball (28) must be struck by the players such that it crosses over the boundary line (54) and bounces initially in the bounce zone (58).

Claims

1. Game apparatus for playing simulated racquetball on an open playing surface by one or more players using racquets, which comprises:

line means positioned on the playing surface for defining a bounce zone and a playing zone separated by a substantially straight boundary line of predetermined length, said boundary line means having a midpoint;

said boundary line means separating the playing zone in which the players move during the game, and the bounce zone on the playing surface;

a base positioned on the playing surface in predetermined spaced apart relationship in a direction substantially normal to the midpoint of said boundary line means, said base being located within the playing zone;

an elastic tether cord of predetermined length in relaxed condition substantially equal to the distance between said base and boundary line means, said tether cord having two ends;

swivel means for rotatably connecting one end of said tether cord to said base;

a resilient ball having a hollow interior and a radial aperture extending between substantially spherical inside and outside surfaces;

an inelastic loop positioned in the aperture of said ball and having inside and outside ends, the outside end of said loop being connected to the other end of said tether cord; and

plug means secured to the inside end of said loop within said ball for preventing separation of said loop from said ball;

said ball having bounce characteristics similar to a standard racquetball and being suitable for repeated bouncing and hitting by racquets held by the players;

said ball, tether cord and boundary line means cooperating such that said ball, when struck with a racquet and hit over said boundary line means, bounces in the bounce zone and is returned by said tether cord and caused to bounce in the playing zone in a manner simulating that in which a free racquetball rebounds from the walls of a conventional enclosed racquetball court.

2. The game apparatus of claim 1, wherein said boundary line means comprises a length of flexible line.

3. The game apparatus according to claim 2, wherein said flexible line is about twenty feet long, thereby approximating the width of a standard enclosed racquetball court.

4. The game apparatus of claim 1, wherein said tether cord is about twelve feet long in relaxed condition and comprises elastomeric material.

5. The game apparatus of claim 1, wherein said base is portable but sufficiently weighty to remain stationary during movement of said tether cord and ball upon play.

6. The game apparatus of claim 1, wherein the other end of said tether cord is looped through said loop, turned back and secured to itself.

7. Game apparatus for playing simulated racquetball on an open playing surface by one or more players using racquets, which comprises:

line means positioned on the playing surface for defining a bounce zone and a playing zone separated by a substantially straight boundary line of predetermined length, said boundary line means having a midpoint;

said boundary line means separating the playing zone in which the players move during the game, and the bounce zone on the playing surface;

a base positioned on the playing surface in predetermined spaced apart relationship in a direction substantially normal to the midpoint of said boundary line means, said base being located within the playing zone;

an elastic tether cord of predetermined length in relaxed condition substantially equal to the distance between said base and boundary line means, said tether cord having two ends;

swivel means for rotatably connecting one end of said tether cord to said base;

a resilient ball having a hollow interior and diametrically opposed radial apertures extending between substantially spherical inside and outside surfaces;

the inside surface of said ball having a raised boss integrally formed therein surrounding each aperture for reinforcing the apertures; and

an inelastic loop extending through the ball apertures and around said ball, the other end of said tether cord being connected to said loop;

said ball having bounce characteristics similar to a standard racquetball and being suitable for repeated bouncing and hitting by racquets held by the players;

said ball, tether cord and boundary line means cooperating such that said ball, when struck with a racquet and hit over said boundary line means, bounces in the bounce zone and is returned by said tether cord and caused to bounce in the playing zone in a manner simulating that in which a free racquetball rebounds from the walls of a conventional enclosed racquetball court.

8. The game apparatus of claim 7, wherein said boundary line means comprises a length of flexible line.

9. The game apparatus according to claim 7, wherein said flexible line is about twenty feet long, thereby approximating the width of a standard enclosed racquetball court.

10. The game apparatus of claim 7, wherein said tether cord is about twelve feet long in relaxed condition and comprises elastomeric material.

11. The game apparatus of claim 7, wherein said base is portable but sufficiently weighty to remain stationary during movement of said tether cord and ball upon play.

12. The game apparatus of claim 7, wherein the other end of said tether cord is looped through said loop, turned back and secured to itself.
