FIELD: games. ^ SUBSTANCE: invention relates to children's teeter. Teeter comprises lever of teeter, which is hingedly installed onto stand with the possibility to change angle of inclination and rotation, weight to balance teeter, gondola to locate spring-loaded seat and hydraulic elements. Roll is rigidly fixed and hydraulic cylinder is hingedly installed on teeter lever, besides weight having stem, one side of which via roll rests onto teeter lever, and the other one - on roll of teeter lever, is hingedly connected to stem of hydraulic cylinder. Hydraulic elements include pipelines, hydraulic pump with hydraulic tank, distributor and hydraulic valve installed under spring-loaded seat, at the same time hydraulic elements are arranged with the possibility to move the weight along teeter lever with hydraulic cylinder stem by means of hydraulic pump in case spring-loaded seat is occupied, and to automatically displace the weight along teeter lever in one of distributor positions as spring-loaded seat is not occupied. Gondola may be arranged in the form of airplane equipped with propeller, body of which accommodates pedal drive of propeller, hydraulic elements and control elements. ^ EFFECT: automatic displacement of weight to balance position in non-loaded condition makes it possible to provide for complete safety of swinging. ^ 2 cl, 3 dwg |
