Abstract

Tightwire sports equipment suitable for use either indoors or out-of-doors. The tightwire or rope is supported at either end by apparatus including horizontal plates. A topmost plate is used for a standing platform and for rope support by having a hole therethrough. The rope curves around a portion of the plate, extends through the hole and is anchored to a base. The base may be the ground, or may be a rigid member such as a wooden beam.

Claims

1. Tight rope apparatus, comprising, in combination:

at least one plate having at least one hole therethrough, at least a portion of said plate being disposed horizontally above a base support;

at least one bar member attached to said plate, extending downward therefrom and supporting said plate at a fixed distance above said base support; and

a rope anchored at one end to said base support by anchoring means, curved around a portion of said plate and frictionally engaged therewith and the other end extending through said hole, said rope being stretched taut and attached to supporting means at its said other end.

2. Apparatus as in claim 1 further comprising:

a second plate attached to said bar member, at least a portion of said second plate being disposed parallel to and resting upon said base support.

3. Apparatus as in claim 2 wherein:

said bar member extends downward beyond said second plate into said base support, thereby bracing said apparatus.

4. Apparatus as in claim 3 wherein:

said anchoring means is a stake.

5. Apparatus as in claim 2 wherein:

said base support comprises an elongated rigid member resting upon a horizontal surface; and

said second plate is attached to said elongated member at one end thereof.

6. Apparatus as in claim 5 wherein:

said elongated member comprises a wooden beam of rectangular cross section; and

wherein said supporting means at said other end of said rope comprises;

a third plate having at least one hole therethrough, at least a portion of said plate being disposed horizontally above said wooden beam;

at least a second bar member attached to said third plate, extending downward therefrom and attached to a fourth plate, said fourth plate resting upon and attached to said wooden beam at the other end thereof, and supporting said third plate at a fixed distance above said wooden beam; and

wherein;

said rope extends through said hole in said third plate, curves around a portion of said third plate and is frictionally engaged therewith and is anchored to said wooden base.

7. Apparatus as in claim 1 wherein:

said bar member being bifurcated into a substantially X-shape, the two upstanding leg portions being attached to said plate, the two downwardly directed leg portions have at their ends thereof two extensions, one of said extensions extending into said base supporT and the other of said extensions resting upon said base support.

8. Apparatus as in claim 7 wherein:

said anchoring means is a stake.

9. Tight rope apparatus, comprising, in combination:

a base support comprising an elongated rigid member;

a first plate attached to said base support at one end thereof;

a second plate attached to said base support at the other end thereof;

at least a first bar member attached to said first plate and extending upward therefrom;

at least a second bar member attached to said second plate and extending upward therefrom;

a third plate, having at least one hole therethrough, attached to said first bar member and being supported by said first bar member at a fixed distance above said first plate;

a fourth plate, having at least one hole therethrough, attached to said second bar member and being supported by said second bar member a fixed distance above said second plate;

a rope attached at either end to either end of said base support, said rope extending through the holes in said third and fourth plates and being stretched taut.

10. Apparatus as in claim 9 wherein said elongated rigid member comprises a wooden beam of substantially rectangular cross section.
