An apparatus for increasing the stability of a tripod includes a centrally placed base member that includes three perimeter leg assemblies, each of which are adapted to cooperate with one of the legs of the tripod. Each of the leg assemblies includes a generally U-shaped member that surrounds a portion of each tripod leg and which cooperates with the base member so that when a portion of each respective leg assembly is tightened, an extension member is urged outward and into contact with an inside surface of one of the legs which, in turn, urges the leg outward until an outside of the leg bears tightly against an inside of the respective U-shaped member. Each tripod leg is accordingly placed under compression eliminating any possible movement thereby. The three forces that urge the legs outward are disposed radially around a center longitudinal axis, each force separated from both adjoining forces by 120 degrees of arc. The U-shaped members include any preferred size or shape and, if preferred, may be attached to the tripod legs.

What is claimed is: 1. A radial tripod stabilizer for stabilizing a tripod structure, comprising (a) a base member that includes a generally planar shape of any preferred thickness, and wherein said base member includes a plane passing through a center thereof, and including a center longitudinal axis that passes through a center of the base member and wherein said center longitudinal axis is perpendicular with respect to said plane; (b) three leg assemblies that are each attached to the base member, wherein each of said three leg assemblies is in an equidistant and spaced-apart radial relationship with respect to a remaining two of said leg assemblies, and wherein each leg assembly is adapted to cooperate with one of three legs of a tripod, and wherein each leg assembly includes a leg member that is detachably-attachable with respect to the base member and which generally includes a U-shape thereto; (c) wherein each leg member is adapted to prevent a leg of said tripod from extending outward with respect to said center longitudinal axis beyond a predetermined distance, and wherein each of said leg assemblies includes means for urging a corresponding one of said tripod legs away from said center longitudinal axis, and wherein said means for urging each of said legs is disposed on said plane, and wherein each of said leg members is disposed on said plane; (d) wherein said means for urging includes an extension member and wherein said extension member is adapted to be urged radially away from said center longitudinal axis, and wherein said extension member is attached to a first end of a threaded rod, and wherein said first end of said threaded rod is adapted to rotate about a center longitudinal axis of said threaded rod with respect to said extension member, and wherein said threaded rod includes external screw threads that are adapted to engage with corresponding screw threads of a threaded opening that is provided in said base member, and wherein said threaded rod is disposed on said plane, and wherein when said threaded rod is rotated about said center longitudinal axis of said threaded rod in a first direction of rotation, and wherein said extension member bears against an inside surface of said one of said tripod legs and urges said one of said tripod legs radially away from said center longitudinal axis until an outside surface of said one of said tripod legs contacts an inside surface of a corresponding one of said leg members when said one of said tripod legs reaches said predetermined distance from said center longitudinal axis, and wherein said corresponding one of said leg members prevents any further outward movement by said one of said tripod legs thereby stabilizing said one of said tripod legs; and (e) wherein each of said leg assemblies is disposed along a longitudinal length of each of said three legs of said tripod at a location that is intermediate an upper end and a lower end of each of said three legs. 2. The radial tripod stabilizer of claim 1 wherein said leg member is detachable with respect to said tripod leg. 3. The radial tripod stabilizer of claim 1 wherein said leg member is fixedly attached to said tripod leg. 4. The radial tripod stabilizer of claim 1 wherein said leg member includes a shape for a portion thereof that corresponds with a cross-sectional shape of said tripod leg. 5. The radial tripod stabilizer of claim 1 wherein said leg member includes a rectangular shape for a portion thereof. 6. The radial tripod stabilizer of claim 1 wherein said leg member includes an arcuate shape for a portion thereof. 7. The radial tripod stabilizer of claim 1 wherein said leg member includes a round shape for a portion thereof. 8. The radial tripod stabilizer of claim 1 wherein said leg member includes an angle that corresponds with an angle that said tripod leg is disposed at during use. 9. The radial tripod stabilizer of claim 8 wherein said leg assembly includes a spring and wherein said spring applies a force sufficient to urge said leg member into a first position of cooperation with said base member and wherein said leg member is retained to said base member when said leg member is disposed in said first position of cooperation. 10. The radial tripod stabilizer of claim 1 wherein said leg member includes a cushion material intermediate a portion of said leg member and said tripod leg. 11. The radial tripod stabilizer of claim 1 wherein said leg member includes a hook that is adapted to cooperate with said leg assembly sufficient to prevent said leg member from being urged away from said base member. 12. The radial tripod stabilizer of claim 1 wherein said extension member includes an angle that corresponds with an angle that said tripod leg is disposed at during use. 13. The radial tripod stabilizer of claim 1 wherein said extension member includes a cushion material intermediate a portion of said extension member and said tripod leg. 14. The radial tripod stabilizer of claim 1 including a knob that is attached to an opposite second end of said threaded rod. 15. The radial tripod stabilizer of claim 1 wherein said extension member includes a channel member that is attached at one end thereof to said extension member and wherein an opposite end of said extension member is disposed in said base member and wherein a portion of said extension member is adapted to slide into said base member and out of said base member a predetermined amount. 16. The radial tripod stabilizer of claim 15 wherein said extension member includes means for preventing it from rotating about a center longitudinal axis thereof when said extension member is disposed in said base member.
