WINDING DEVICE FOR STOPPING OF HOLES IN WALLS Russian patent published in 2015 - IPC E06B9/66 E06B9/40 E06B9/64 

FIELD: transport.

SUBSTANCE: invention relates to winding device for stopping the holes (2) in walls. Winding device (30) comprises flat resilient long closer (35) revolved by actuator assembly (4) sign of rotation and winding element (29 acting on said closer (35). Sign of rotation of aid winding element (29) defines winding of said closer (35) on or unwinding it from element (29). there is adjusting element to up or down moving top edge of closer (35 in winding without winding of moving top edge. Transfer elements are used for interaction between actuator assembly (4) and winding element (29) and provided with winding pull element (21). The latter is arranged between first spinning winding body (33) and second body (34) so that pull element (21) can be wound or unwound by first winding body (33). The latter can be actuated by assembly (4). Second winding body (34) and winding element (29) are engaged to revolve. Closer (35) can be wound by unwinding pull element (21) from second winding body (34). Winding element (29) is arranged for adjustment of closing surface so that closer (35) two partial areas (27, 28) arranged on both sides of element (29) can be wound on or unwound from element (29). Compensating means are arranged so that winding element (29) can take different positions across winding element lengthwise axis. Said compensating means have sliding element to make second winding body (34) directed in preset path unless top edge of closer (35) downs or ups. Lower edge of closer (35) does not displace up or down.

EFFECT: accelerated winding, possibility to take up high loads.
