HIP JOINT OF EXOSKELETON Russian patent published in 2015 - IPC A61F5/00 A61H1/00 A61H3/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. Hip joint of exoskeleton contains lumbar belt for fastening hip joint to human waist, fastened to lumbar plate, to which boat-shaped arm, fastened with screws with plug, is connected. Plug ends are rigidly fastened on end slots of central rod. Central rod is placed in openings of pair of bushings, which are inserted one into the other, placed perpendicularly to longitudinal axis of central rod and form degree of hip joint mobility in frontal plane. Ends of internal bushing are inserted with possibility of rotation into pair of bushings, placed coaxially with bushings and having opposite ends welded to internal surface of ring in such a way that longitudinal axis of end is perpendicular to axes of bushings and central rod. On external surface of ring rigidly fastened is electric engine stator, connected with electric accumulator, electric engine rotor is held by rollers, which form radial-stopping bearings. Device is equipped with wave transmission with bodies of rolling, which consists of input unit with two eccentrics, separator, in which placed are bodies of rolling - rollers, and which is rigidly fastened to ring. Rigid wheel with internal profile is output unit of wave transmission. Rod, equipped with elements of fastening to human leg, is rigidly fastened to external surface of hard wheel. Bodies of rolling - rollers of wave transmission also fulfil function of stopping bearing of output unit of exoskeleton hip joint.

EFFECT: invention ensures increase of exploitation and ergonomic characteristics, as well as reliability due to ensuring possibility of creating simple hip joint of exoskeleton, which does not constrain human motion, reinforcing work of muscles by means of electric drive and reducing load on person's musculoskeletal system after accumulator discharge.
