Definitions

the invention relates to a climbing protection ladder consisting of a vertical central spar and horizontal rungs, the central spar having a C-shaped cross section with a front longitudinal slot, opposite flat back web and rounded longitudinal edges adjoining it, and the rungs in the region of the back web from the outside to the central spar are attached to this and are pre-angled with their free outer parts.
Fall arrest ladders of the type in question are intended to protect a user from a possible crash and serious injuries.
the user has to wear a safety harness with a safety device, which is inserted into the longitudinal slot of the central spar and can be automatically fixed in the central spar.
the rungs of such climbing protection ladders can be made from single rungs, i.e. H. Rungs, which alternately extend in opposite directions from the central spar, but also consist of double rungs, each extending in both directions.
the invention has for its object to form a climbing ladder of the type mentioned in such a way that even if relatively large manufacturing tolerances are allowed, a simple yet functionally fully satisfactory rung assembly is possible retrospectively.
the rungs are provided with an isosceles-trapezoidal recess for the back web, with which they are placed in the area of the rounded longitudinal edges like a rider seat on the central spar and are connected to the central spar by a clamp fastening.
the invention is based on the knowledge that the inevitable problem of manufacturing tolerances by the in a certain amount of variable rider seat attachment of the rungs to the central spar can best be managed. At the same time, this rider seat attachment leads to an optimal absorption or introduction of the forces occurring when climbing the climbing protection ladder. At the same time, the interior of the central spar remains practically completely free. In any case, the clamp fastening also allows the rungs to be retrofitted without, for example, damage to a previously applied corrosion protection.
the rungs could easily be designed as forgings, as in the known climbing protection ladder from which the invention is based. According to a preferred embodiment, however, the rungs are bent from profile bar material.
the clamp attachment could consist of a latching connection, for example with latching lugs which can be latched into latching recesses on the rung and / or on the central strut or back web.
the clamp fastening consists of rivets which penetrate the back web and the rungs, is safer and sufficiently simple.
the climbing protection ladder shown in the figures consists of a vertical central spar 1 and horizontal rungs 2.
Fig. 1 it can be seen that the rungs 2 are designed as double rungs.
the possible embodiment as single rungs is indicated in FIG. 1 by the dotted line 3.
the central strut 1 has a C-shaped cross section with a front longitudinal slot 4.
the back web 5 opposite the longitudinal slot 4 is essentially flat; this does not rule out the fact that it has protruding bulges in the central spar 1, which serve to fix the catching device, not shown.
a rounded and bulged longitudinal edge 6 connects to the two longitudinal ends of the back web 5.
the rungs 2 are attached to the central strut 1 in the region of the back web 5 and connected to it. 1 that the rungs 2 are pre-angled with their free outer parts 7, so that the upwardly angled free outer ends 8 lie in the plane of the longitudinal slot 1.
Fig. 1 it can again be seen that the rungs 2 are provided with an isosceles-trapezoidal chamber 9 for the back web 5. With this chamber 9, the rungs 2 are placed like a rider seat on the central spar 1, in such a way that they only in the area of the! rounded longitudinal edges 6 bear against the central strut 1. In this position they are then connected to the central strut 1 by a clamp 10.
the rungs 2 are bent from an L-shaped profile bar material.
the clamp 10 consists of rivets that pass through the back web 5 and the rungs 2. It goes without saying that due to the rider seat-like arrangement of the rungs 2 between the back web 5 and the rungs 2 in the region of the recess 9, a small distance is left to ensure the tolerance compensation.
