Abstract

A power generating device that includes a dynamo, a rack mounted on the frame of a bicycle to hold the dynamo, and a wheel attached to the rack. When the device is engaged, the wheel contacts the ground and rotates to drive the dynamo while the bicycle is in motion, causing the dynamo to generate electricity.

Independent Claims | See all claims (4)

  1. 1. A power generating device in combination with a bicycle comprising: a dynamo, a rack mounted on a frame of said bicycle, said dynamo being mounted on said rack, and wheel means independent of wheels of said bicycle, said wheel means being mounted on said rack such that said wheel means rotate when said device is actuated and said bicycle is in motion due to contact with a surface upon which said bicycle is moving, mechanical energy of said wheel means being converted into electrical energy by said dynamo; wherein said rack comprises: a front mounting frame affixed to said frame of said bicycle, a rear mounting frame connected between a rear part of said front mounting frame and chain stays of said bicycle, a movable frame, said movable frame having a first end pivoted to said rear mounting frame and a second end coupled to said dynamo and said wheel means, an upper barrel and a lower barrel affixed to said frame of said bicycle, a tubular control rod inserted through said upper barrel and said lower barrel and pivoted to said movable frame; wherein said control rod is moved between a first position in which said movable frame is lifted so that said wheel means are not in contact with the ground, and a second position in which said movable frame is moved downward to cause said wheel means to be in contact with the ground so that said wheel means are rotated to operate said dynamo when said bicycle is in motion.
  2. 3. A power generating device in combination with a bicycle comprising: a dynamo, a rack mounted on a frame of said bicycle, said dynamo being mounted on said rack, and wheel means independent of wheels of said bicycle, said wheel means being mounted on said rack such that said wheel means rotate when said device is actuated and said bicycle is in motion due to contact with a surface upon which said bicycle is moving, mechanical energy of said wheel means being converted into electrical energy by said dynamo; and wherein said rack comprises: a front mounting frame affixed to said frame of said bicycle, a rear mounting frame connected between a rear part of said front mounting frame and chain stays of said bicycle, a movable frame, said movable frame having a first end pivoted to said rear mounting frame and a second end coupled to said dynamo and said wheel means, an upper barrel and a lower barrel affixed to said frame of said bicycle, a tubular control rod inserted through said upper barrel and said lower barrel and pivoted to said movable frame; wherein said control rod is moved between a first position in which said movable frame is lifted so that said wheel means are not in contact with the ground, and a second position in which said movable frame is moved downward to cause said wheel means to be in contact with the ground so that said wheel means are rotated to operate said dynamo when said bicycle is in motion, and shock-absorbing spring means are coupled between said movable frame and said wheel means.
