Patent Images
1. A portable support frame for a tennis net having its longitudinal axis extending horizontally, comprising:
- a. a stable, horizontally disposed base;
b. a vertical support member rigidly attached at one of its ends to said base;
c. means for attaching the top of said tennis net to the remote end of said vertical support member providing support substantially at the center of said net;
d. a pair of beam support members, each of said pair being pivotally attached at one of its ends to said base, said pair of beam support members extending upwardly and outwardly from said base on opposite sides of said vertical support member, said beam and vertical support members being substantially in the same vertical plane; and
e. means for attaching the outer, top ends of said tennis net to the remote ends of said beam support members, said beam support members forming cantilever beams when said tennis net is attached thereto.

Abstract
A portable support frame for a tennis net having a stable, horizontal base to the center of which is rigidly attached a vertical member for supporting the top center of a tennis net. Pivotally attached to and extending from each side of the base are beam support members the remote ends of which are attached to the top corners of the tennis net so that the tennis net is supported by two cantilever beams and the vertical support member all in the same vertical plane.

11. A game device, comprising:
-
a. a stable, horizontal base; b. a rectangular planar net said net being supported on said base in a substantially vertical plane with its longitudinal axis extending substantially horizontal; c. a vertical support member, one end being rigidly attached to said base and the other end being attached to the top center of said net; d. a pair of beam support members, each having a first and a second end, said beam support members being pivotally attached at their first ends to opposite sides of said base, said beam support members extending upwardly and outwardly from said base on opposite sides of said vertical support member, the second end of each beam support member being attached to and supporting an outer, top end of said net, said beam support members forming cantilever beams with said net and holding the top edge of said net taut. - View Dependent Claims (12, 13)

14. A portable support frame for a tennis net, having its longitudinal axis extending substantially horizontal, comprising:
-
a. a horizontal, stable base frame comprising two like, integral base frame members each formed of a center section, two side sections extending obliquely from the ends of the center section and at substantially the same angle thereto, and a flange extending from the remote end of each side section, being substantially parallel to said center section; b. a vertical support member having a base forming an inverted T, the base of said vertical support member being sandwiched between said center sections of said base frame members, said base frame members and vertical support member being rigidly joined together; c. means on the remote end of said vertical support member for attaching the top, center of said tennis net; d. a pair of axles, each being mounted to and extending between opposing flanges, the ends of said axles projecting through said flanges, said axles being substantially parallel to each other; e. a wheel secured to each projecting end of each of said axles; f. a pair of beam support members, one end of each of said beam support members being pivotally attached to the center of a respective one of said axles for allowing pivotal movement of each beam in a vertical plane, said vertical and beam support members being in substantially the same vertical plane; g. means on the remote ends of said beam support members for attaching the outer, top ends of said tennis net, said beams forming cantilever with said tennis net and holding the top edge of said tennis net taut; h. a pair of sleeves encompassing each of said axles, one of said sleeves being on each side of the attached end of each beam support member and between said beam support member and one of said flanges; and i. two pairs of sway restraint braces, the braces of each pair of which being attached at one end to a respective one of said beam support members, the other ends of each pair of sway restraint braces being pivotally attached to the opposite ends of the respective axles between said sleeves and said flanges for allowing pivotal movement of each brace in a vertical plane. - View Dependent Claims (15, 16, 17)
