Fixed ladder, in particular for lighting masts

The present innovation concerns a fixed ladder * in particular for lighting masts, with a central spar, from which ladder rungs protrude alternately on both sides, which are provided with an anti-slip device at the end.

The present innovation is based on the task of designing such a ladder so that the assembly is carried out particularly easily and safely and at the same time an easy-to-climb ladder is obtained.

According to the present innovation, this is achieved by that the ladder rungs have a horizontal section inserted through a stile designed as a U-profile, which lies parallel to a transverse axis of the spar, and a further horizontal section which is at an acute angle to the first section in the direction of the climber of the ladder.

According to a preferred embodiment, the fixed ladder is the acute angle about 15 °.

The two ladder rung sections are a further refinement of the innovation and the anti-slip device formed in one piece from a hot-dip galvanized iron bar profile.

The fixed ladder according to the present innovation is then described on the basis of the drawing. Show it:

Fig. 1 is a view of the ladder from the front, *

Fig. 2 is a horizontal section through the ladder along the Line 2-2 of Figs. 1 and

3 shows an individual illustration of the anti-slip device.

The fixed ladder has a stile 1 designed as a U-profile, through which the ladder rungs are inserted alternately on both sides. Each ladder rung has a first horizontal section 2, which runs parallel to a transverse axis of the stile, and a further horizontal section 2> which is inclined at an angle of approximately 15 ° to the first ladder rung section 2. The end of each ladder rung is formed by a vertical section 4, which is integral with the sections

th 2 and 3 is formed, the ladder rung preferably consists of a hot-dip galvanized iron bar profile. Due to the kink formed in the ladder rung between In Sections 2 and 3, the ladder rung is automatically prevented from moving in the stile because its other end is at 6 is secured by welding the rung to the stile.

At the same time, by relocating the ladder rung section 5 forwards towards the climber makes it easier to climb the ladder.

The spar 2 is provided with a number of openings 7 which Fastening elements for fastening the spar to the mast 5 take up.
