A SYSTEM FOR COVERING A SWIMMING POOL
A system for covering a swimming pool, comprising a sheet (T) which can be rolled around a drum (D). The winding and unwinding movements of the sheet are controlled by a motorized unit (2). The sheet (T) has a first end edge associated with the winding drum (D), two longitudinal side edges guided within stationary side guides (G) and a second end edge with which two traction cords are associated (C), for pulling the sheet (T) towards the unwound condition. The two traction cords (C) are engaged around return rollers (4), in such a way that each cord has a forward run (C1), which extends from the sheet (T), on a longitudinal extension of the sheet, and a return run (C2), ending up at a winding device (R) mounted coaxially to the winding drum (D) of the sheet (T). The motorized unit (2) comprises a first motor (M1) for controlling the winding drum (D) of the sheet, and a second motor (M2) for controlling the winding device of the two traction cords (C), which comprises two separate wheels (R) placed coaxially with the winding drum (D) of the sheet (T), adjacent to the two ends of the drum (D). The drum (D) has a tubular cylindrical body (11). The two winding wheels (R) of the two traction cords (C) are connected to each other by means of a central shaft (5) extending through the tubular body (11) of the drum (D). The second motor (M2) is mounted coaxially with the central shaft (5) and has an outlet shaft (18) connected in rotation with the central shaft (5). The first motor (M1) is mounted on an axis parallel to, and spaced apart from, the axis (6) of the central shaft (5), and controls the winding drum (D) of the sheet through a transmission (20, H, 21), for example, a chain transmission.
