FIELD: satisfaction of vital human requirements.
SUBSTANCE: invention relates to supporting structure, in particular, intended for disabled persons, to assist them in movement in daily life, possibly without additional assistant. Supporting structure (100) comprises two pairs of legs (2) and four wheels (2w), each of which is located on lower end of corresponding one of legs. Each leg comprises upper segment (2u) and lower segment (2l) and optionally extending segment (2e) for contact with ground instead of corresponding wheel. Such supporting structure is capable of lowering motion, while maintaining crossed position of legs on both lateral sides. Such supporting structure is able to help disabled person to move on the ground and on stairs.
EFFECT: technical result is providing smooth and continuous motions with variable speed, reduced weight and dimension characteristics, as well as possibility of folding to reduce overall dimensions.
