CURTAIN SHUTTING DEVICE Russian patent published in 2015 - IPC B60R5/04 

FIELD: machine building.

SUBSTANCE: curtain shutting device (10) contains a canvas (40), a shaft (70) windings, the housing (50) with a hole (60), a gripping bar (20) connected to the far end of the canvas (40) and a locking hook (30). A hole is formed in an angular section which is formed by a top section (53) and lateral section (54). The top end section (51) is shifted from the bottom end section (52) towards the pulling of the canvas (40). The locking hook (30) has a front surface (30b) and a bottom surface (30a). The distance between the top end section (51) and the lower end section (52) of the hole (60) exceeds the distance between the front surface (30b) of the locking hook (30) and the end of the gripping bar (20). The top end section (51) of the hole prevents the movement of the hook (30), gripping bar (20), and canvas (40) towards the winding in the position in which the front surface (30b) of the hook (30) rests against the top end section (51) of the hole (60) when winding the canvas (40). The bottom end section (52) supports the bottom surface (30a) of the hook (30) in the position in which the bottom end section (52) is located opposite to the bottom surface (30a) of the hook. The locking hook (30) is kept by the housing (50) when the end of the gripping bar (20) enters the hole (60) across the lower end section (52) towards the winding.

EFFECT: possibility of keeping of the gripping bar in horizontal position.
