Sports training ladder
A sports training agility ladder is usable in a flat ladder position with the ladder rungs on or close to the ground. The ladder may also be moved into and used in a hurdle position where a bridge or center section of each rung is raised up off of the ground. The ladder accordingly provides advantages of an agility ladder and of hurdles. Each rung may have permanently attached left and right tubes forming a frame. Left and right elastic cords may extend through the left and right tubes. The ladder is consequently easily and compactly folded up for storage and transport, and quickly and easily unfolded for use in either the ladder position or the hurdle position.
1. A sports training ladder, comprising:
a plurality of rungs with each rung it eluding a bridge having a left end pivotally attached to an upper end of a left riser, and a right end pivotally attached to an upper end of a right riser;
a left fitting at a lower end of the left riser and a right fitting at a lower end of the right riser;
a left pole attached to the left fitting and a right pole attached to the right fitting, with the left pole substantially perpendicular to the left riser and the bridge, and with the right pole substantially perpendicular to the right pole and the bridge; and
with the ladder movable from a ladder position wherein the risers are substantially parallel to the bridge, to a hurdle position wherein the risers are substantially perpendicular to the bridge.
2. The ladder of claim 1 wherein the ladder has a width AA when in the ladder position and a width HH when in the hurdle position, and wherein the ratio of HH to AA ranges from 0.5 to 0.9.
3. The ladder of claim 2 wherein ratio of HH to AA ranges from 0.6 to 0.8.
4. The ladder of claim 1 with substantially each bridge having at least one bridge hinge tab and each riser having at least one riser hinge tab, and with a hinge pin extending through the bridge and riser hinge tabs to pivotally attach the bridge to the riser.
5. The ladder of claim 1 wherein the left riser, the riser, and the bridge have the same cross section shape and dimensions.
6. The ladder of claim 5 with the left riser, the right riser and the bridge comprising hollow tubes.
7. The ladder of claim 6 with the left riser, the right riser and the bridge having rectangular tubular cross-sections.
8. The ladder of claim 1 further comprising a stop surface at the upper end of the left and right riser.
9. The ladder of claim 1 with substantially each rung comprising a frame including the bridge, the left and right risers permanently attached to the bridge, the left and right fittings permanently attached to the left and right risers, a left tube permanently attached to the left fitting and a right tube permanently attached to the right fitting.
10. The ladder of claim 1 further including a left elastic cord extending through the left tube and the left fitting and a right elastic cord extending through the right tube and the right fitting.
11. The ladder of claim 1 wherein the bridge is straight and flat.
12. The ladder of claim 1 wherein the risers are straight and flat.
13. The ladder of claim 1 wherein the left riser is identical to the right riser.
14. The ladder of claim 1 wherein the left fitting is identical to the right fitting.
15. The ladder of claim 1 with the left and right fitting each having a flat bottom surface.
16. A sports training ladder, comprising:
a first rung including a first bridge having a left end pivotally attached to a first left riser, and a right end pivotally attached to a first right riser; a first left fitting on the first left riser and a first right fitting on the first right riser; and a first left pole permanently attached to the first left fitting and a first right pole permanently attached to the first right fitting, with the first left pole substantially parallel to the first right pole and with both poles substantially perpendicular to the first bridge;
a second rung including a second bridge having a left end pivotally attached to a second left riser, and a right end pivotally attached to a second right riser; a second left fitting on the second left riser and a second right fitting on the second right riser; a second left pole releasably attached to the first left fitting and permanently attached to the second left fitting, and a second right pole releasably attached to the first right fitting and permanently attached to the second right fitting, with the second left pole substantially parallel to the second right pole and with second left and right poles substantially perpendicular to the second bridge.
17. The ladder of claim 16 further comprising a third rung including a third bridge having a left end pivotally attached to a third left riser, and a right end pivotally attached to a third right riser; a third left fitting on the third left riser and a third right fitting on the third right riser; and a third left pole releasably attached to the second left fitting and permanently attached to the third left fitting, and a third right pole releasably attached to the second right fitting and permanently attached to the third right fitting, with the third left pole substantially parallel to the third right pole and with the third left and right poles substantially perpendicular to the third bridge.
18. The ladder of claim 17 further comprising a left elastic cord extending through the first, second and third left poles and the left fittings, and a right elastic cord extending through the first, second and third right, poles and the right fittings.
19. The ladder of claim 17 with the ladder movable from a ladder position wherein the riser and the bridges are substantially flat on the ground, to a hurdle position wherein the bridges are from 3 to 30 cm up off of the ground.
