A system for aiding the crawling mobility of children or young adults is disclosed. The system consists of central hub supported by four legs. The patient is enclosed in a harness which is coupled to a support cord extending through the central hub. A lifting force partially offsetting the patient's weight is supplied by tension on the support cord, which is locked relative to the central hub via a locking device. Coupling between the support cord and harness is provided by carabineers which are clipped to “D” rings on the harness. The balance point can be adjusted by moving the attachment point to various “D” ring locations.

1. A system for aiding the crawling mobility of a human or animal occupant by providing a lifting force for the occupant while the occupant is crawling over a surface, comprising: a first support leg having a first end and a second end, said second end having a first caster attached thereto;a second support leg having a first end and a second end, said second end having a second caster attached thereto;a third support leg having a first end and a second end, said second end having a third caster attached thereto;a fourth support leg having a first end and a second end, said second end having a fourth caster attached thereto;a hub, said hub having a first cavity, a second cavity, a third cavity, and a fourth cavity fashioned therein, said first end of said first support leg being inserted within said first cavity of said hub, said first end of said second support leg being inserted within said second cavity of said hub, said first end of said third support leg being inserted within said third cavity of said hub, said first end of said fourth support leg being inserted within said fourth cavity of said hub, said first through said fourth support legs being oriented with respect to said hub in a manner such that said first through said fourth casters are in contact with said surface;a support cable, said support cable extending through a center of said hub, said support cable having an attachment end portion situated below said hub;a harness device, said harness device extending around at least a portion of the occupant, said harness device having a plurality of attachment devices mounted thereto, said plurality of attachment devices aligned in a linear array along a spine of said occupant;a coupling device, said coupling device operative to connect said attachment end portion of said support cable to one or more of said plurality of attachment devices mounted on said harness device;a locking device, said locking device operative to fix a position of said support cable relative to said hub, said locking device having a port fashioned therein, said support cable extending through said port fashioned in said locking device, said locking device having serrated edges protruding into said port, operative to engage said support cable when a locking force is applied axially to said locking device, forcing said serrated edges into said support cable, fixing said support cable relative to said hub;wherein a point of attachment of said coupling device to one or more plurality of attachment devices within said linear array along said spine of said occupant alters a balance point of said lifting force, while said support cable is under tension and while said support cable is free of tension. 2. The system as recited in claim 1, wherein said locking force applied axially to said locking device is applied by a spring. 3. The system as recited in claim 1, wherein said first support leg, said second support leg, said third support leg, and said fourth support leg are non-rotatably attached to said hub. 4. The system as recited in claim 1, wherein said coupling device is a pair of carabineers. 5. The system as recited in claim 1, wherein said coupling device is a single carabineer. 6. The system as recited in claim 1, wherein said plurality of attachment devices mounted to said harness device are “D” rings. 7. The system as recited in claim 6, wherein said harness device comprises an upper section and a lower section. 8. The system as recited in claim 7, wherein said “D” rings are attached to said upper section.
