Embodiment Construction

[0018] Such as figure 1 and figure 2 As shown, the fall device 100 has housings 110 , 120 in which a rope drum (not shown) is rotatably supported for winding and unwinding the safety line 105 . A safety line 105 protrudes through a (not shown) line hole at the lower end of the housings 110,120.

[0019] A spool (not shown) is rotatably supported in the housings 110,120. When a person who wants to be connected to the safety rope 105 pulls the rope downwards and unwinds it from the drum, a (not shown) return spring (Rückholfeder) is tensioned, which returns the spring when the person unties the rope and releases the rope. Pull the rope up again and wind it on the drum. The fall safety device 100 also has a (not shown) locking mechanism that allows the drum to rotate to unwind the rope when the rope is slowly pulled downward at a small speed, but when the rope is pulled at a high speed The locking mechanism locks the rotation in the sense of unwinding the safety rope 105 whe...

Abstract

The invention relates to a crash safety device having a safety rope (105) wound onto a drum, a recuperating spring tensioned by the drum during the winding of the rope, and a locking device for blocking the drum from rotation in the rope unwinding direction during the crash of a person secured by the rope. A rope drive mechanism is provided in order to unwind the rope (105) from the drum and to slowly move the rope end having a hook (290) attached thereto toward such that a person can hook onto the safety rope (105). The drive mechanism has a motor (140) driving a rope drive wheel (210) via a freewheel (200) for lowering the rope end having the hook (290). In order to rewind the rope, the motor (140) is operated in a reverse direction of rotation at a controlled rotational speed in order to limit the speed at which the rope (105) is pulled up by the tensioned recuperating spring.

Description

technical field [0001] The invention relates to a fall safety device with a safety rope which can be locked in the event of a fall of a person secured and fixed. Furthermore, the invention also relates to a drive mechanism for a safety rope of a fall safety device. Background technique [0002] Such fall protection devices are known in the prior art, see eg UK patent document 1552667 and European patent application 0247818. These devices have a drum rotatably supported in a housing for winding or unwinding a safety line. When unwinding, the return spring is tensioned, which rewinds the rope when the person releases it. A locking device is located in the drum, which prevents further unwinding of the rope in the event of a sudden fall of a person connected to the rope. A line to which a person can be attached protrudes through a hole in the lower end of the fall protection device and is provided with an attachment hook. [0003] Known fall safety devices, sometimes called ...
