Bird scaring device

A bird scaring device comprising:

• a frame;
• visual means attached to said frame for reciprocal rectilinear movements between active and inactive positions for scaring birds;
• and
• actuator means operatively connected to said visual means for moving said visual means between said inactive and active positions, said actuator means including means for ejecting a gaseous stream in a predetermined path and at increased velocity;
• said visual means including target means disposed in said predetermined path so as to present a surface against which said gaseous stream impinges, said visual means moving from said inactive position and into said active position in response to impingement of said gaseous stream upon said surface of said target means;
• said visual means including motion converting means for converting linear motion of said visual means into rotary motion in response to said visual means linearly moving from said active position and into said inactive position, wherein
• said motion converting means includes means defining a track to establish a spiral course in a fixed position relative to said visual means, and roller means attached to said visual means so as to be moveable therewith, said roller means engaging said track when said visual means moves from said active position to said inactive position along said linear path and for following said spiral course established by said track to responsively translate the linear movement of said visual means into rotary movement, whereby said visual means rotates upon movement from said active position to said inactive position;
• said roller means including a pair of axles each having one and other ends, said axles being pivotally mounted to said visual means at said one end thereof so as to be pivotally movable between first and second position, and rollers journalled to respective said axles at said other end thereof.
