Swing drive mechanism

A drive mechanism for a swing suspended by a suspension arm having a T-shaped top end, comprising:

• a motor-driven rotating horizontal drive shaft with a spur gear affixed thereto;
• a vertical gear wheel coupled to said spur gear through meshed gears;
• an extension spring joined at one end to said vertical gear wheel, and at the other end to one side arm of said T-shaped top end of said suspension arm through a pivotal linking member;
• and
• a stop on said suspension arm preventing said linking member from pivoting into alignment with said extension spring.

A drive mechanism for a swing suspended by a suspension arm, comprising:

• a motor-driven rotating drive shaft;
• a first gear wheel coupled to said drive shaft through a first set of meshed gears;
• a second gear wheel coupled to said drive shaft through a second set of meshed gears;
• a first extension spring joined at one end to said first gear wheel and at the other end to said suspension arm;
• and
• a second extension spring joined at one end to said second gear wheel and at the other end to said suspension arm.

A drive mechanism for a swing suspended by a suspension arm having a T-shaped top end defined by first and second side arms, comprising:

• a motor-driven vertical rotating drive shaft with a worm gear affixed thereto;
• a first gear wheel meshed with said worm gear;
• a second gear wheel meshed with said worm gear;
• a first extension spring joined at one end to said first gear wheel and at the other end to said first side arm;
• a second extension spring joined at one end to said second gear wheel and at the other end to said second side arm;
• and
• means for maintaining said first and second extension springs each in a bowed configuration.

A drive mechanism for a swing suspended by a suspension arm, comprising:

• a motor-driven horizontal rotating drive shaft having a spur gear affixed thereto;
• a first gear wheel in mesh with said spur gear through a reduction gear;
• a second gear wheel in mesh with said first gear wheel directly;
• a first extension spring joined at one end to said first gear wheel, and at the other end to said suspension arm through a first pivotal linking member;
• a second extension spring joined at one end to said second gear wheel, and at the other end to said suspension arm through a second pivotal linking member;
• and
• first and second stops preventing said first and second linking members respectively from pivoting into alignment with said first and second extension springs respectively.
