Open top swing & control

An open top swing comprising:

• a seat;
• a pair of hangers connected to said seat;
• a free standing support frame pivotally supporting said hanger, said support frame comprising:
• a rear base;
• first and second opposed legs extending upwardly at an angle from ends of said rear base;
• a front base;
• third and fourth opposed legs extending upwardly at an angle from ends of said front base,
• wherein said first and third legs converge toward each other, and said second and fourth legs converge toward each other;
• a first connector attached to said first and third legs for maintaining said first and third legs at a fixed position relative to each other;
• a second connector attached to said second and fourth legs for maintaining said second and fourth legs at a fixed position relative to each other;
• a first axle journaled for rotation on said first connector;
• a second axle journaled for rotation on said second connector;
• a hub mounted to each of said first and second axles, wherein one of said hangers is mounted to one of the hubs and the other of said hangers mounted to the other of said hubs;
• and
• a swing drive mechanism mounted on said one of said first and second connector and operatively connected to respective one of said first and second axle for oscillating said seat, wherein said swing drive mechanism has means for selectively controlling the degree of rotation of said first and second axles.

A swing drive mechanism adapted for a swing that includes a supporting frame and an axle operatively connected to a hanger suspending a seat comprising:

• a drive sleeve adapted for mounting coaxially and rotatably about said axle, wherein said sleeve is rotatable relative to said axle;
• a drive flange adapted for mounting on said axle;
• a drive flange coupling device positioned between said drive sleeve and said drive flange and adapted to cause said axle to oscillate with said drive sleeve;
• a crank linked to said sleeve for oscillating said sleeve;
• and
• a motor for rotating said crank.

An open top support frame for a swing having a pair of hangers suspending a seat comprising:

• a rear base;
• first and second opposed legs extending upwardly at an angle from ends of said rear base;
• a front base;
• third and fourth opposed legs extending upwardly at an angle from ends of said front base, wherein said first and third legs converge toward each other, and said second and fourth legs converge toward each other;
• a first connector attached to said first and third legs for maintaining said first and third legs at a fixed position relative to each other;
• a second connector attached to said second and fourth legs for maintaining said second and fourth legs at a fixed position relative to each other;
• a pivot operatively mounted to said first connector;
• a second pivot operatively mounted to said second connector;
• a hub mounted to each of said first and second pivots, wherein one of said hangers is mounted to one of the hubs and the other of said hangers mounted to the other of said hubs;
• and
• an overrotation stop mounted to each of said hubs and a cooperating overrotation stop mounted to each of said first and second connectors adjacent each of said hubs, wherein said stop and said cooperating stop prevent overrotation of said hubs relative to the first and second connectors.
