A swing apparatus suspended from overhead and providing substantially pendular motion, said swing apparatus comprising:
- a. a seating platform comprising substantially vertical lateral sides, a substantially horizontal base, and a seat for the occupants, said seat being rigidly attached to said horizontal base between said lateral sides of said seating platform;
- b. first and second pairs of vertical hangers connected at upper and lower ends to attachment means which accommodate rotation of said first and second pairs of vertical hangers about an axis perpendicular to the seating platform longitudinal axis;
- c. said first pair of vertical hangers being spaced laterally outside said lateral sides of said seating platform to provide head and body clearance for said occupants;
- d. said second pair of vertical hangers being offset at a distance from said first pair of vertical hangers along said seating platform longitudinal axis and spaced laterally outside said lateral sides of said seating platform to provide head and body clearance for said occupants;
- e. said upper attachment means of said first and second pairs of vertical hangers being supported from overhead;
- f. said lower attachment means of said second pair of vertical hangers being secured to said seating platform;
- g. a linkage mechanism for initiating and sustaining said swing apparatus pendular motion, said linkage mechanism comprising:
- aa. a first pair of vertical links, having upper and lower ends;
- bb. a horizontal link having handgrips and providing head and body clearance for said occupants;
- cc. said first pair of vertical links being spaced laterally about said seating platform longitudinal axis;
- dd. said upper ends of said first pair of vertical links being pivotally attached to said horizontal link;
- ee. said lower ends of said first pair of vertical links being pivotally attached to said seating platform at said horizontal base;
- ff. said lower attachment means of said first pair of vertical hangers being secured to said horizontal link;
- gg. wherein said occupants alternately pull and push at said handgrips of said horizontal link to initiate and sustain said swing apparatus pendular motion.
