#CMT# #/CMT# The device (1) has electric motorized units arranged inside a rigid frame (4) to drive a motorized rotation axle (6). A rolling bar is fitted to a flexible cover, and the axle is arranged in a bottom position with respect to a basin for rolling the cover around a rotating bar. Rolling elements move the frame with respect to the basin during the rolling of cover. Immobilization unit i.e. support foot (31), immobilizes the frame relative to the basin. An elevator unit formed by a support (14) arranges the axle in top position with respect to the basin for unrolling of the cover above basin. #CMT#USE : #/CMT# Device for assisting rolling/unrolling of a flexible cover above a basin of a swimming pool. #CMT#ADVANTAGE : #/CMT# The support foot immobilizes the frame with respect to the basin, and the elevator units formed by the support arranges the motorized axle in the top position with respect to the basin for unrolling the cover above the basin rapid manner, without generating a frictional force on the cover, thus avoiding deviation of rolling bar in a direction different from the direction in which the cover extends. The device assists the rolling of the cover in order to prevent the person from accidental fall into the basin of swimming pool. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a flexible cover rolling/unrolling assisting device whose motorized axle is placed in top position. 4 : Rigid fame 6 : Motorized rotation axle 14 : Support 22 : Orifices 31 : Support foot. |
