Patent ID: 7497792

Claim:
A training device for use by a lacrosse player to practice checking an offensive player, comprising: a base; a main post extending generally vertically from said base; an arm operatively coupled to said main post and extending outwardly therefrom, said arm having a distal end and a proximal end, said arm being rotatable about a fixed point between said distal end and said proximal end; means for holding a lacrosse stick adjacent said distal end of said arm; an activating member operatively coupled to said main post and extending outwardly therefrom, said activating member being configured to separate a user from said distal end of said arm; an actuator operatively coupled to said arm proximal end and said activating member, wherein said actuator translates linear movement of said activating member into non-linear movement of said arm, wherein said actuator includes: a rack gear defined by said activating member; a pinion gear having a configuration complementary to a configuration of said rack gear, linear movement of said rack gear in a first direction causing rotational movement of said pinion gear in a first direction; a spiral spring operatively coupled to said pinion gear, said rotational movement of said pinion gear in said first direction causing said spiral spring to move from a biased configuration to a wound configuration; a cam operatively coupled to said spiral spring, movement of said spiral spring from said wound configuration to said biased configuration causing movement of said cam; and an internal recess defined by said proximal end of said arm, said internal recess housing said cam, said movement of said cam causing said arm to pivot about said fixed point in an oscillating manner.
