Definitions
- the invention relates to a fall protection for liftable Gates and the like, such as rolling gates, sectional gates, rolling grilles, Roller shutters and the like, with suspension cables at the bottom Gate area near the side, in the upper gate opening area preferably curved, gate guide rails for am Attack gate-mounted castors, consisting of at least a spring-loaded lever on which one of the Cables in a direction counteracting the spring force attacks, and a clamping element for a clamping, the Interlocking engagement with the gate guide rail or with an element running parallel thereto, that if the suspension cable becomes slack or breaks the lever with its clamping element under the spring force in the engagement position is pivoted.
- liftable Gates and the like such as rolling gates, sectional gates, rolling grilles, Roller shutters and the like
- suspension cables at the bottom Gate area near the side, in the upper gate opening area preferably curved, gate guide rails for am Attack gate-mounted castors, consisting of at least a spring-loaded lever on which one of the Cables in
- fall protection devices are used, particularly in the case of power-operated devices Gates, in addition, in a purely mechanical way direct impact on the guide rail of the gate this bring to an immediate standstill if the rope breaks or becomes limp for any other reason.
- the well-known Fall protection devices of the type mentioned at the outset are on the inner surface of the door leaf screwed to it and are with one behind the guide rail, with the Provide gate with moving support element, which has a lateral, d. H. in the door leaf level from the guide rail continued relocation of the gate when the Fall protection limited.
- the invention limits operator safety Bracket unnecessary and at the same time the Braking effect and holding force of the fall protection significantly improved.
- the risk of false trigger in one Selectively reduced gate opening state which in the known fall protection devices is particularly problematic, that is, when the bottom end of the gate is already close to it highest position and therefore it is reduced due to the Tensile load on the suspension cable is most likely to become slack of the suspension cable can come, namely in the position of the gate in which the lower roller is located in the bending area of the guide rail and the risk of jamming in the known fall protection systems is particularly large.
- the invention Operator endangering and an increased risk of damage Including installation of the fall protection on the door leaf avoidable by a problem-free, Integration arrangement of the fall arrest system which is much less dangerous in the door leaf itself and on the side of it subsequent area within the door leaf thickness.
- a rough adjustment of the suspension cable length in the immediate spatial Made in connection with fall protection in particular by an effective inside the door leaf Adjusting screw or worm-driven winding drum.
- the door leaf 10 for example, a liftable sectional door
- a fixed Gate guide rail 13 mounted and guided with low friction.
- the Goal guide rail 13 leaves relatively little play for lateral movements of the roller 14 at right angles its axis of rotation 14 A.
- a V-shaped tread area 13 A the gate guide rail 13 ensures good centering the roller conveyor in the normal case.
- the opposite, yourself Legs 13 B extending parallel to the roller axis of rotation on the other hand, is straight.
- the roller 14 on the opposite side is a clamping element 21 having lever 20, the pivot axis X is parallel extends to the plane spanned by the door leaf 10 and thus also parallel to the axis of rotation 14 A of the roller 14.
- the pivot shaft 18 carrying the lever 20 is within the Door leaf 10 stored in a suitable manner.
- the clamping element 21 is non-rotatably connected to the lever 20, but sits in the other rotationally fixed on the left in Figure 3 front end of the swivel shaft 18.
- the lever 20 is constructed in several parts. It consists of a first lever 20 A, the is rotatably attached to the pivot shaft 18 and points an abutment 22 on which a coil spring 23rd supports with one end.
- the coil spring 23 wraps around the pivot shaft 18 and is at its second end fixed on the door leaf 10 by means of a bolt 24.
- the spring force F of the coil spring 23 tries the lever 20 A from its roughly parallel door leaf operating position to swivel at right angles to the door leaf level. This will in normal door operation prevents the suspension cable 11, which in the lower gate area in a trumpet-shaped Opening 25 inserted into the door leaf and there in adjustable length Way is fixed by the gate weight taut is held, as shown in Figure 2.
- the suspension cable is now approximately at right angles to it vertical course of the spring-loaded lever 20 A cross-loaded. If the suspension cable tension is sufficient, is the reaction force R of the suspension cable 11 on the lever 20 A. greater than the opposite spring force F with the consequence that the eccentric and provided with friction teeth clamping element 21 with the leg 13 B of the door guide rail 13 is disengaged.
- the fall protection is fine-tuned using a second lever 20 B, which is free on the pivot shaft 18 is rotatably mounted and has a guide leg 26, on which the suspension cable 11 is held in precise position (during normal gate operation).
- Adjustment screw 27 lies on the back of the guide leg 26 of the lever 20 B and transmits the spring force F on the suspension cable 11. By turning the adjusting screw 27, the reaction force R is set sensitively.
