Claim 1
Independent Claim
286 words
A training sled comprising a frame section, a plurality of channel runners symmetrically disposed with respect to the center line of the sled, each runner having a flat surface adapted to engage the ground, means for mounting said frame section to and above said channel runners, a plurality of spaced blocking pad supports, means for mounting said blocking pad supports to and forwardly of said frame section, a first set of rollers disposed between one pair of runners to one side of the center line of said sled, a second set of rollers disposed between a second pair of runners to the other side of the center line of said sled, axle means for rotatably supporting each of said rollers in a normal ground engaging position wherein said channel runners are out of engagement with the ground, a single operator''s platform carried by said frame section at a position substantially on the center line of said sled, operating means supported to said frame section adjacent said platform and connected to said axle means for selectively controlling the position of said rollers between said normal ground engaging position and a raised position clear of the groUnd to thereby selectively vary the effective engagement of the surfaces of said channel runners with the ground and further including a vertically adjustable chute, a first rod member connected at one end to said chute, a vertical chute adjustment rod, means connecting the other end of said first rod member to said chute adjustment rod, said first rod member adapted to be disposed in a substantially horizontal position for maintaining said chute forwardly of and above said blocking pad supports, and means for adjusting the height of said chute adjustment rod.
