APPARATUS FOR MOVING OVER UNEVEN TERRAIN

Apparatus (100) for moving over uneven terrain (102) including a support element (17), a pair of cams (5, 5') rotatingly attached to the support element (17), wherein one of the cams (5, 5') is shaped as the mirror-image of the other cam, a pair of runners (1, 1') each having a terrain contacting surface (90) and a cam/runner contacting surface (2, 3), and a pair of lifters (108, 108') each connected to one of the runners (1, 1'), each lifter (108, 108') having a cam/lifter contacting surface (2', 3'), the runners (1, 1') and the lifters (108, 108') being alternatively moved by the cams (5, 5'), wherein when one of the cams (5, 5') contacts the cam/runner contacting surface (2, 3) of one of the runners (1, 1'), the terrain contacting surface (90) of the runner (1, 1') contacts a terrain (102) thereby causing the apparatus to move in a direction of travel, while simultaneously the other cam (5, 5') contacts the cam/lifter contacting surface (2', 3') and lifts the lifter (108, 108') away from the terrain (102), thereby also lifting the other runner (1, 1') away from the terrain (102), and vice versa, such that the runners (1, 1') move along the terrain (102) by alternately contacting the terrain (102).
