DE10053716C2 - Quick-fit back railing for ladders - Google Patents

Description

A conductor fuse is already known which is permanently attached to such conductors are permanently connected to a building and in which conductor fuses from 10 meters Rising height must be attached (DE 197 57 202 A1). These ladders may then be without additional fuses are used.

However, this type of ladder fuse cannot be mounted on single ladders and the Assembly of the permanently attached ladder requires an enormous amount of work.

Back railings are also known, which are designed as short sections and on the Spars are hooked in (JP abstract 11117649). But such ladder fuses are not safe enough.

At present there is no obligation to secure a ladder height of 3 to 5 meters, even though one A scaffold must already be placed from a working height of 3 meters. It can even go until 7 Meters of hell can be worked from a ladder without securing, taking the risk of falling is certainly even higher. With a ladder over several days without There is a ladder protection workplace to be found at a building height of 5 meters constantly a great risk of accidents.

The invention is based on the problem of a permanently attached and heavy design design of the ladder fuse in such a way that it can be easily removed and attached z. B. is made possible with leaning ladders to thereby significantly reduce the risk of accidents countries.

This problem is solved by a quick-mounting back railing with the in claim 1 Features listed solved. Advantageous further developments are in the subclaims specified.

The advantages achieved by the invention are in particular that instead of a sweat ladder fuse permanently and permanently attached to buildings etc. is easy and simple che conductor protection is created, the simple and easy attached and removed again can be taken. Due to the light design, e.g. B. made of aluminum, and with we few adjustments to adjust the adjustable brackets to the respective Ladder spar width, the ladder protection can be attached to all common system ladders which significantly reduces the risk of accidents.

The quick-fit back railing can be made of metal or of stable plastics manufactured the lattice frame by a net or a tube or from individual tunnelarti against ironing. But you could also use a foldable, foldable or extendable tunnel-like one  Attach the ladder fuse to the ladder or wear a ladder fuse without it de Holme and adjustable brackets, but only a tunnel-like shape on the one can hold on well and squeeze each other to the side Adjust and fix conductor width.

Embodiments of the invention are shown in the drawings and are in following described in more detail. Show it:

Fig. 1 a base part mounted on a printed circuit,

Fig. 2 side view of a ladder with a base and a head portion,

Fig. 3 top view and side view of a holder on the rung and

Fig. 4 section through a quick-fit back railing mounted on a single ladder.

In Fig. 2 is a single ladder with a base and a head part of the ladder fuse Darge provides, in which the head part is attached to a scaffold hook with a fastening chain. In the lattice frame shown, the height from the rung is approx. 70-80 cm, the width approx. 60 cm, it is made of a welded aluminum tube frame.

In Fig. 3 a holder is shown with which the supporting bars are attached to the rungs of the ladder.
