FIELD: construction.
SUBSTANCE: structural unit with hinges and guides includes rotary unit, where connection element, having blocking part, and guide, having guide part, are connected so that they may be folded with each other. Sliding element is connected to guide part so that to provide for sliding, and rotary working part is provided at its one end. Rotary element comprises blocking clamp, which is installed with the possibility of rotation on guide and is blocked in blocking part or released from blocking part in compliance with angle of rotary element turn. The latter includes latch, which is blocked in rotary working part in compliance with position of sliding element in process of displacement and is turned so that blocking clamp may be released from blocking part or from rotary working part and is turned in reverse direction so that blocking element is blocked in blocking part. When sliding element slides along guide part, blocking clamp perceives torque of hinge spring so that high friction forces from hinge spring do not occur between guide element and element of sliding type.
EFFECT: sliding element may slide smoothly, preventing formation of nicks.
