The invention relates to an improvement in training devices, in particular, training devices for the pole vault exercise. The apparatus propels a person into the air, and after obtaining the desired point of inertia, provides support for projecting the person beyond this point of inertia. The apparatus therefore simulates the pole vault procedure, wherein, the approach to the clearance bar is eliminated, the pole and the athlete are propelled vertically from a lower, more horizontal position to a higher, more vertical position, thereby, providing a safe, efficient, and effective tool for mastering the “in-flight”technique of the pole vault acitvity.

An apparatus for propelling a person upward and projecting the person beyond a point of inertia comprising; a retracting-elastic assembly for propelling a person upward, additional means for propelling the person upward, attached to said retracting-elastic assembly, a rigid horizontal member, means for attachment of said rigid horizontal member to said retracting-elastic assembly, said rigid horizontal member serving as support means for both the propelling force and the additional propelling force, a first hand grip member pivotably joined at one end to said retracting-elastic assembly by a first flexible cable, said first hand-grip member comprising gripping means for the person as he is propelled upwardly, a elastic tension device pivotably joined at one end to the opposing end of said first hand grip member by a second flexible cable, said elastic tension device and the second flexible cable serving to facilitate the propelling of the vertical member vertically from a lower, more horizontal position to a higher, more vertical position, said elastic tension device being more compact and having a greater stiffness coefficient than that of said retracting assembly, a rigid vertical member, means for attachment of said rigid vertical member to said tension device, said rigid vertical member serving as the support means for the projecting force, whereby a person will be propelled upward and projected beyond a desired point of inertia, thus simulating the second part of the pole vault technique.
