MECHANICAL EXOSCELETON FOR LOWER EXTREMITIES

摘要

The utility model is intended for situations when a person, along with walking, needs to be in a static pose of a half-squat or squat for a long time. Such situations can arise during installation work in production, in particular when assembling cars, or in agriculture during planting or harvesting. The technical result, which consists in providing increased usability by adjusting the position of the squat or squat with the seat locked while providing assistance when standing up from the pose of the squat or squat and facilitating the possibility of turns in the knee joint. The achievement of such a technical result was made possible by using a mechanical exoskeleton for the lower extremities (ES) containing the lumbar attachment to the human body, the right and left femoral nodes, the right and left knee nodes, the right and left knee nodes, the right and left stack nodes, the right and left bearing nodes. The right femoral, knee, ankle and stack nodes are connected in series. The left femoral, knee, tibia and stack nodes are connected in series. The right support node connects the right femoral and ankle nodes. The left bearing node connects the left femoral and tibial nodes. The lumbar attachment to the human body is made in the form of a waist belt for attachment to a person’s waist. Right and left femoral nodes, each has a femoral beam and a seat assembly. The femoral beam has an upper end for attachment to the lumbar attachment to the human body by means of fastening tapes, with one end of the tape being attached to the waist belt and the other to the upper end of the femoral beam, and the lower end for attachment to the knee assembly. The femoral beam is made along with four sides, on which a longitudinal groove is made on each of which has such a cross section that the output part is narrowed and the inner part is expanded. The first groove is located opposite the second, and the third opposite the fourth. The first groove is located on the side closest to the thigh than the second. The fourth groove is located on the side closest to the outer lateral side of the thigh than the third. The seat assembly has a seating element, femoral belts connected to the landing element. The landing element has a landing and fixing straps interconnected. A cracker is attached to the free side of the mounting plate to be located in the first groove of the femoral beam to allow the landing element to slide. The right and left knee nodes, each has straps for attaching the human tibia, an upper transverse beam for attaching to the lower end of the femoral beam, an average transverse beam for attaching to the tibial knot, and two frames located in parallel planes. Each frame consists of two docked L-shaped plates - the first and second. Each of the L-shaped plates has a connecting long arm and a fastening short arm. The connecting long shoulders of the first and second L-shaped plates with the ends are pivotally connected in the middle of the frame. The fixing arm of the first L-shaped plate is fixed end to the upper transverse beam. The fixing arm of the second L-shaped plate with the end fixed motionless to the middle transverse beam. Straps for attaching the human tibia are fixed on the long connecting shoulders of the second L-shaped plates. The right and left tibial nodes each have a lower transverse beam for attachment to the stacking unit and an ankle beam that has an upper end for attachment to the middle transverse beam and a lower end for attachment to the lower transverse beam. The right and left stack nodes, each has a rectangular plate frame, two triangular plate frames, two supporting bases - right and left and straps for attaching the foot. Straps for attaching the foot are fixed on both sides of the triangular plate frames. Supporting bases, each made in the form of a hook-shaped plate, which has bent sides on three sides of the hook part - for the right base in one direction, and for the left in the other, and bent triangular sides at the edges opposite each other along the longitudinal straight part of the hook-shaped plate. The bases of the triangular sides are a continuation of the sides of the hook part, and the vertices are located at the end of the longitudinal part of the plate. The hook parts of the support base plate are fixedly mounted at the ends of the lower crossbeam. On the short opposite edges of the plate-shaped rectangular frame, the bases of the triangular plate-like frames directed in the same direction with their vertices are fixed across. The vertices of the triangular plate frames are pivotally connected to the ends of the longitudinal straight parts of the hook-shaped plates so that their sides are opposite each other. The right and left load nodes each have
