Definitions

  • the invention relates to a securing arrangement for climbing devices like ladders, according to the preamble of claim 1.
  • Such a safety arrangement for climbing devices such as Ladders have been known for a long time. Fuse arrangements must to be used in accordance with the regulations if the Ladder exceeds a certain height and no back protection is provided is.
  • a rail is usually in the middle and parallel attached to the ladder on which a fuse runner is slidably mounted.
  • the belay runner should on special and at a distance of at most 14 cm the provided recesses to prevent the ladder user from falling, who, for example, with a harness with the Fuse runner is connected to prevent.
  • the ladder user should move upwards be hindered as little as possible. Therefore there are safety hooks proven that are withdrawn in the upward movement so that they are out of engagement of the catch holes on the rail.
  • DE-U1-298 11 906 a device for removing and putting on the rotor one Horizontal security became known. It is a specially designed one Rail piece provided that the removal of the backup rotor should facilitate.
  • this solution is complex manufacture and has the disadvantage that the security function is lifted at the transfer point, so here special Caution is appropriate.
  • the invention is therefore based on the object of a fuse arrangement for climbing devices such as ladders according to the Generic preamble of claim 1 to create the more manageable is, but still has greater operational reliability.
  • the solution according to the invention allows for the first time the belay runner also on the way, i.e. over the course of the rail anywhere or notch anywhere Surprisingly, without affecting the security function becomes. Rather, this option increases the Acceptance of the backup runner clearly, so that by the more intensive Use ensures that an increased level of There is security for the conductor user.
  • an anti-rotation device is additionally provided, which prevents incorrect installation of the fuse runner.
  • the anti-rotation device realized in or on a jaw of the circuit breaker is and is realized, for example, so that a closing of the backup rotor is prevented with certainty if the Backup runner is accidentally placed incorrectly.
  • the anti-rotation device is as Gravity control designed to be free from the possible User action works and automatically in the wrong one Position of the backup runner whose activation is blocked.
  • an anti-rotation device by a known Profile element is realized, the insertion at the entrance or the exit or, if necessary, a transfer station the rail is prevented if the belay runner is the wrong one Takes position.
  • a rounded projection on one the jaws should be provided with a one-sided Lock works together on the rail and with correct alignment of the fuse runner allows insertion, when twisted Position prevented this however.
  • the backup runner according to the invention is also strong suitable for pollution-prone environments and in particular also regardless of the contamination status of the rail, so that increased security requirements can be taken into account.
  • the fuse arrangement 10 shown in FIG. 1 has one Fuse runner 12 on the slide 14 on a rail is.
  • the safety runner 12 has a moving jaw and a fixed jaw 18, each having grooves 20, 22 in which the Rail 14 is guided, as can also be seen from FIG. 2.
  • the rail 14 has a plurality of one another vertically spaced locking openings 24, for the engagement of the securing hook 26 are determined.
  • the safety hook 26 is pivotable on a middle Bolt 28 mounted which extends between the jaws 16 and 18.
  • two bolts 30 and 32 are provided also extend between the jaws 16 and 18.
  • the shape of the securing hook 26 can essentially be seen in FIG. 3 remove, where he a in a conventional manner Has eyelet 36 to which a safety rope can be attached.
  • the arrangement of the bolts 28 to 32 can also be shown in FIG. 3 remove.
  • a section line A-A can be seen that the 5 corresponds to the section.
  • Fig. 5 shows the fuse runner according to the invention - but the For the sake of simplicity, without the safety hook 26 - in section.
  • the bolts 28 and 32 have a fairly large diameter, so that a corresponding dimensional stability and security against rotation is given while the bolt 30 of the additional guide serves.
  • a compression spring 40, 42 and 44 is provided in each sleeve, whereby by the design of the construction and the orientation the compression spring ensures that the spring direction the jaws 16 and 18 press against each other.
  • the movement jaw has 16 an anti-rotation device 50 as a locking element.
  • the anti-rotation device 50 blocks the movement of the movement jaw 16 towards the fixed jaw 18 when the safety runner 12 is not in the correct position, i.e. not in the position as shown in Fig. 5, but rotated by 180 °. In this position, a securing component 52 falls into one Recess in the bolt 28 so that even when actuated of a release pin, not shown in the figure, a pushing together of the two jaws is not possible.
  • the anti-rotation device 50 is completely encapsulated and protected against contact introduced so that manipulation from the outside not possible.
