Claims
- 1. A tripod apparatus, comprising:
- a generally horizontally disposed head casting;
- first, second, and third legs pivotally connected to said head casting and extending downwardly and outwardly therefrom, said first, second, and third legs having selectively adjustable lengths so that in use said head casting can be caused to be generally level despite irregularities of the surface upon which said apparatus base is supported;
- first, second, and third support members affixed to said head casting;
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the proximal end of said third leg; and
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the distal end of said third leg.
- 2. The tripod apparatus of claim 1 wherein said first, second, and third legs each have a generally horizontal foot pad pivotally and detachably connected to the distal end of the said first, second, and third leg; and wherein said first, second, and third legs are selectively detachable from said head casting; and further wherein a continuous and adjustable length of rope is threaded through apertures at the distal end of each of said first, second, and third legs so as to provide stability to the base of said apparatus.
- 3. The apparatus of claim 2 further including a rope clamp, wherein the ends of said rope are threaded through said rope clamp and the length and tension of said rope controlled thereby.
- 4. A bipod apparatus, comprising:
- a generally horizontally disposed head casting;
- first and second legs spaced generally equally from the center of said head casting, pivotally connected to said head casting, and extending downwardly and outwardly therefrom, said first and second legs having selectively adjustable lengths so that in use said head casting can be caused to be generally level despite irregularities of the surface upon which said apparatus base is supported;
- a support member affixed to one vertical side of said head casting;
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the proximal end of said second leg; and
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the distal end of said second leg.
- 5. The bipod apparatus of claim 4 wherein said first and second legs each have a generally horizontal foot pad pivotally and detachably connected to the distal end of said first and second leg; and wherein said first and second legs are selectively detachable from said head casting; and wherein a continuous and adjustable length of rope is threaded through apertures at the distal end of each of said first, second, and third legs.
- 6. The bipod apparatus of claim 5 further including a rope clamp, wherein the ends of said rope are threaded through said rope clamp and the length and tension of said rope controlled thereby.
- 7. A quadripod apparatus, comprising:
- a generally horizontally disposed head casting;
- first, second, third, and fourth legs pivotally connected to said head casting, and extending downwardly and outwardly therefrom, said first, second, third, and fourth support members affixed to the exterior perimeter of said head casting; said first, second, third, and fourth legs having selectively adjustable lengths so that in use said head casting can be caused to be generally level despite irregularities of the surface upon which said apparatus is supported;
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the proximal end of said fourth leg; and
- an internal sheave pulley incorporated into an aperture and connected with a retention pin axle to the distal end of said fourth leg.
- 8. The quadripod apparatus of claim 7, further comprising:
- a first, second, third, and fourth generally horizontal foot pad pivotally and detachably connected to the distal ends of said first, second, third, and fourth legs, respectively; said first, second, third, and fourth legs being selectively detachable from said head casting; said first, second, third, and fourth legs having apertures at their respective distal ends; and
- a continuous and adjustable length of rope threaded through said apertures at the distal ends of each of said first, second, third, and fourth legs.
- 9. The apparatus of claim 8 further including a rope clamp wherein the ends of said rope are threaded through said rope clamp and the length and tension of said rope controlled thereby.
