Claim:
A portable jump training apparatus ( 50 ) for releasably securing to an external mounting surface ( 10 ) to measure an athlete's vertical leap, comprising: (i) a jump measurement device ( 100 ) having a plurality of vanes ( 110 ) rotatably mounted to a vane mounting post ( 120 ), a frame member ( 130 ) having a vertical post ( 132 ) and at least one support arm ( 134 ), wherein the vane mounting post ( 120 ) is joined to the at least one support arm ( 134 ); (ii) a height adjustment post ( 200 ) joined to the vertical post ( 132 ), such that the height adjustment post ( 200 ) is spaced apart from the vertical post ( 132 ) a post separation distance ( 136 ); (iii) an external surface mount ( 300 ) having at least one adjustable gripping device ( 310 ) to releasably secure the external surface mount ( 300 ) to the external mounting surface ( 10 ), and a translation guide ( 320 ) configured to slidably receive the height adjustment post ( 200 ) such that the jump measurement device ( 100 ) may translate adjacent an outer surface of the translation guide ( 320 ) as the height adjustment post ( 200 ) translates within the translation guide ( 320 ) so that the position of the jump measurement device ( 100 ) and the height adjustment post ( 200 ) may be adjusted with respect to the stationary external surface mount ( 300 ); and (iv) a height adjustment lock ( 400 ) for releasably locking the height adjustment post ( 200 ) to the translation guide ( 320 ) to lock the jump measurement device ( 100 ) at a desired height.
