Abstract
A merry-go-round having seats for both riders and children who want to propel the merry-go-round with a pair of crank mechanism that are offset to ensure that their is no "dead spot" to make start up of the merry-go-round difficult with the merry-go-round including a pair of pivoting handles for children to propel the merry-go-round with octagonal shaped circumferential seating and foot support areas to support the children's feet above the ground and a pair of safety hand rails for riding children to hold onto and to prevent the riding children from coming in contact with the pivoting handles.
Claims11
A merry-go-round for children to ride comprising:
- a support base;
- a center post extending vertically upward from said support base;
- a frame rotationally mounted to said center post, said frame including a circumferential seating area for children to sit on and a circumferential foot support to support the feet of the children above said support base, said frame including hand safety rails for riding children to grasp as the riding children sit on said circumferential seating area;
- a first crank mechanism having a dead spot and a second crank mechanism having a dead spot, said first crank mechanism and said second crank mechanism operable to permit children located on said seating area to rotational propel said frame about said center post, each of said crank mechanisms connected to a vertically pivoting handle that can be operated by a child sitting on said circumferential seating area, said first crank mechanism angularly offset by less than 180 degrees from said second crank mechanism so that at least one of said crank mechanism will not be in said crank mechanisms dead spot.
A merry-go-round that can be started and propelled by children seated on the merry-go-round while other children ride the merry-go-round comprising:
- a support base;
- a center post extending vertically upward from said support base;
- a frame, said frame rotationally mounted on said center post;
- an annular shaped seating area and an annular shaped foot support located on said frame, said foot support extending below said annular shaped seating area to prevent the feet of children from getting caught on the ground or said frame as the merry-go-round spins around:
- a first and a second semicircular shaped safety rails for riders on said merry-go-round to hold onto as said merry-go-round rotates about said center post;
- a first plate said first plate having a center and a circumferential area, said center of said first plate connected to said center post;
- a first pin connected to said circumferential area of said first plate, said first pin and said first plate forming a first crank with a dead spot;
- a second plate located in a spaced parallel relationship to said first plate, said second plate having a center and a circumferential area, said first pin connecting said first plate to said second plate;
- a central axis extending through said center post and said center of said first plate and said center of said second plate;
- a second pin extending upward from said circumferential area of said second plate, said first pin and said second plate forming a second crank with a dead spot said first crank located above said second crank, said central axis, said first pin and said second pin positioned so as not to be in a straight line to thereby prevent said first crank from being located in said dead spot of said first crank when said second crank is located in said dead spot of said second crank;
- a first handle pivotally mounted to said frame and said first crank to permit a first child on said merry-go-round to rotational propel said frame by applying a force to said first crank;
- and
- a second handle pivotally mounted to said frame and said second crank to permit a second child on said merry-go-round to rotational propel said frame by applying a force to said second crank so that the first child and the second child can start and propel said merry-go-round with riders on said merry-go-round.
