Abstract:
An apparatus for use in association with an all terrain vehicle, comprising, in combination:(a) a frame assembly consisting of first arm member and a second arm member having respective anterior and posterior ends, said arm members being oriented in substantially diverging configuration relative to one another, at least one cross member bridging said first and second members wherein said first member, said second member and said cross member define a frame having a substantially A-shaped configuration, said frame having a front end and a back end, wherein said frame is adapted to be attached to the vehicle body of said all terrain vehicle such that said frame is oriented substantially parallel to the ground, said front end extending forwardly between the front wheels of said all terrain vehicle and said back end extends rearwardly and upwardly such that the posterior ends of said first member and said second member are respectively oriented substantially adjacent said vehicle body; (b) mounting means for securing said frame to said vehicle body, wherein said mounting means comprises means for attaching the posterior ends of said first member and said second member to said vehicle body; (c) a blade assembly adapted for mounting to the front end of said frame assembly; (d) angle adjustment means for adjusting the angle of said blade assembly relative to the longitudinal axis of said all terrain vehicle, comprising means for pivotally connecting said blade assembly to said front end of said frame to enable the orientation of said blade assembly relative to the longitudinal axis of said all terrain vehicle to be angularly adjusted, locking means to releasably secure said blade assembly in a desired angular orientation relative to said longitudinal axis of said all terrain vehicle, and a dual-handled lever for operating said locking means from either side of said all terrain vehicle; and (e) an over center lift means to facilitate the raising and lowering of said blade assembly in a substantially vertical plane relative to the ground and for enabling the operative locking and unlocking of said blade assembly in a desired vertical position relative to the ground, said over center lift means comprising: a handle for actuating said over center lift means; cable and pulley means operatively connected to said handle, said cable and pulley means comprising a pulley attached to the front end of said frame assembly, a lift cable having a first end and a second end, wherein said lift cable runs through and operatively engages said pulley, said first end of said lift cable being releasably attached to the frame of said all terrain vehicle; lever means operatively assembled to translate the force from actuation of said handle to said cable and pulley means, said lever means comprising a vertical axis pivot arm having a first end connected to said handle and a second end connected to said second end of said lift cable and a pivot arm stop adapted to prevent said pivot arm from moving beyond a point wherein said lift cable has passed over the vertical axis of said pivot arm.
