Definitions
- the invention relates to a fall arrester for a fall arrest system for preventing a person from falling from a ladder, a platform or the like.
- the safety gear runs in a guide rail.
- the person to be secured wears a safety harness and is connected to the safety device by a connecting means.
- the catching device has a runner or slide which runs in the guide rail.
- the rotor has a housing and a pawl rotatably mounted in it, which is loaded by a spring. The spring pushes the pawl into a locked position. In the event of a crash, the pawl then bumps against catches or a perforation in the guide rail.
- the connecting means is attached to a stop point of the pawl. To dismount, the pawl is pivoted into an unlocked position against the force of the spring.
- Such a fall arrester which is suitable for a fall arrest system, is known from EP-A-0 168 021, DE-A-27 36 037 and DE-A-19 61 757.
- a guide rail with a C-profile is used in these fall arrest systems.
- the edges of the longitudinal opening of the C-profile are the guide flanges on which the safety gear is guided.
- catches are pressed out or recesses are perforated, against which the pawl runs in the event of a crash, so that the locking takes place in a form-fitting manner.
- the pawl points downwards so that the pawl runs over the catches or the perforations in the rear wall of the C-profile when climbing up.
- the user leans back (back pull) so that the
- the pawl is pulled away from the rear wall of the guide rail and the slide can travel downwards unhindered.
- the connecting line between the pivot point of the pawl and the attachment point encloses an acute angle of approximately 30 ° with the horizontal and the pawl is pivoted by approximately 25 to 30 ° from the fully unlocked to the fully locked position.
- the pawl is pressed into the locked position by a relatively strong spring.
- the pivot point of the pawl is approximately in the middle between the two axes of the rollers to distribute the load and abrasion to the rollers.
- a catching direction is known in which the stop point in the unlocked position lies above the horizontal going through the pivot point of the pawl.
- the safety gear can only be used for dismounting without a back pull, because the back pull would pull the pawl into the locked position.
- the object of the invention is a safety device with which one can climb into narrow shafts without problems (dismounting without back pull), but which can also be used in the usual way on ladders (dismounting with back pull).
- this object is achieved in that the catching device is unlocked when the connecting line between the pivot point of the pawl and the attachment point forms an angle with the horizontal of less than 2 ° and that the spring exerts a torque on the pawl that is smaller than that the weight of the safety gear generated torque when the safety gear is held at the point of deflection.
- an angle of about 2 ° to the horizontal is established in the connecting means, the person applying a force of up to about 600 N into the connecting means.
- This angle can be slightly smaller (0 °) or larger (4 °) due to different friction between the rotor and the guide rail or the condition of the guide rail. If you now want to descend unhindered, the pawl must remain pulled through the back pull in this area from 0 ° to 4 °.
- the stop point of the pawl is below the horizontal going through the pivot point of the pawl.
- the connecting line between the stop point and the pivot point of the pawl preferably forms an angle of approximately 5 ° with the horizontal when the pawl is in the unlocked position. This ensures that the pawl is safely in the unlocked position when dismounting with the back pull.
- the pawl preferably reaches the locked position by pivoting only about 15 °.
- the pawl protrudes so far from the underside of the runner that it against the catch or the holes in the rear wall of the Guide rail bumps.
- the distance of the tip from the pivot point is as large as possible.
- the pivot point is preferably at the top of the rotor and the tip of the pawl at the bottom.
- the rotor is an approximately rectangular housing with a central opening.
- the pawl is pivoted in the central opening around a horizontal axis of rotation.
- the safety gear is guided by guide devices in the guide rail.
- the guide devices rest on the outside and inside of the guide flanges of the guide rail.
- the guide devices are provided at the upper and lower ends of the rotor and, as is known from DE 299 06 047, can each have two pairs of standing rollers.
- two additional standing rollers are provided in the catching device according to the invention, which are in use within the guide rail, the pivot point of the pawl being approximately between these additional rollers and the guiding device at the upper end of the catching device.
- Figure 1 shows the catching device in an isometric view from the top right front
- Figure 2 shows the catching device in an isometric view from the top right rear
- Figure 3 shows the catching device in vertical section, the forces occurring when dismounting with back pull are illustrated and
- Figure 4 shows the catching device in vertical section, the forces occurring when dismounting without back pull are shown.
- the fall arrester 10 forms the movable part of a fall arrest system and runs in a guide rail.
- the secured person wears a safety harness and strikes the catching device 10 with a connecting means and a snap hook. The secured person is thereby held in the event of a crash.
- the catching device 10 has a housing 12 with a central opening 14, in which a pawl 16 is mounted so as to be pivotable about a horizontal axis 18.
- guide devices 20, 22 are provided for guiding the catching device 10 in the guide rail.
- the guide rail has the C profile known from DE 299 06 047 with guide flanges along the opening in the front of the C profile and with a rear wall.
- the catching device 10 is guided in this opening.
- the guide devices each consist of four standing rollers 24, which are arranged in pairs, so that one roller 24 rolls on the inside of the guide flanges and one on the outside of each pair.
- the axes of rotation of the rollers 24 are parallel to the horizontal axis of rotation 18 of the pawl 16. to ⁇ rt • Ü N n_ ⁇
- the arrow 40 is the tensile force acting on the deflection point 34. It therefore points vertically upwards. Since the connecting line between the axis of rotation 18 and the opening 34 is approximately horizontal, the maximum torque acts on the pawl 16.
- the spring 36 presses approximately in the middle between the axis 18 and the opening 34 against the pawl 16.
- the force of the spring 36 which is represented by the arrow 44, is chosen so that the torque it exerts on the pawl 16 is smaller than the torque generated by the tensile force 40.
- the size of the pulling force 40 is determined by the weight of the catching device 10. It is opposite to the weight shown by arrow 46.
