摘要：
1. A swivel assembly for pivotally connecting a first section of a frame to a second section of a frame, comprising:! means forming the working axis of rotation, around which the second section of the frame is rotated when in the working position relative to the first section of the frame； and! means forming a pivot axis for folding around which the second frame section is rotated when the second frame section is folded and laid out between the operating position and the transport position. ! 2. The node according to claim 1, in which the working axis of rotation is lower in vertical direction than the axis of rotation for folding when in the working position. ! 3. The node according to claim 1, in which the second section of the frame rotates approximately 25 degrees around the working axis of rotation when in the working position. ! 4. The assembly according to claim 1, further comprising a pivot plate connected to the first section of the frame by means of a first pin forming a rotational axis, wherein the second section of the frame is connected to the rotary plate by a second pin forming a pivot axis for folding. ! 5. The node according to claim 4, additionally containing a slot and a pin connection between the second section of the frame and the rotary plate, while the slot and the pin connection provide rotation of the second section of the frame relative to the first section of the frame while in the working position. ! 6. The assembly according to claim 4, further comprising an actuator having a retractable and retractable element, wherein the actuator is connected between the first section of the frame and the rotary plate to rotate the rotary plate around the first pin to move the second section of the frame between the slave1. Шарнирный узел для поворотного соединения первой секции рамы со второй секцией рамы, содержащий: ! средство, образующее рабочую ось поворота, вокруг которой поворачивается вторая секция рамы при нахождении в рабочем положении отно
