Definitions
- the invention relates to a rung or step ladder two spars and pull-out tips arranged at the lower end of the spars for securely anchoring the ladder in the ground.
- Soil used is legal to prevent accidents prescribed to provide tips at the lower end of the spars, with which the ladder is securely anchored in the ground can be. It is mostly steel tips that permanently mounted or in the extended state by 70 mm above the project the lower end of the bar.
- pull-out tips are used in the previously known conductors guided in guides placed on the spars from the outside.
- the pull-out tips are at least in the extended position Lockable condition with a pin.
- the present invention proposes a sprout or Step ladder with two bars and arranged at the lower end of the bars Extension tips for securely anchoring the ladder in the ground, characterized according to the invention is that the spars at least in their lower area than Profiles are formed and the pull-out tips inside the Profiles are guided. For the guidance of the pull-out tips so now none protruding from the outside of the spars Parts more needed.
- the pull-out tips are rather elegantly integrated into the interior of the spars. The handling the guides are in no way hindered by the guides.
- the profiles can have at least two in their walls Locking openings for one arranged at the pull-out tips Have locking projection.
- the locking openings are preferred arranged in such a way that there is a first end position in which they don't have one at the bottom Overhang the arranged ladder foot, and a second End position in which it is at a prescribed distance of protrude at least 70 mm above the ladder foot.
- the Snap connection between the bars and the pull-out tips can can be easily achieved by the fact that the pull-out tips by spring force against the walls of the profiles in the Area of the locking openings.
- the locking openings are arranged on the inside of the spar to unintentional loosening of the locking connection as possible avoid.
- the locking projections can be bolts with a rounded tip be used to release the pull-out tips from the respective Press the locking position inwards and release it from the locking opening to let.
- Fig. 1 shows the lower end of a spar 10 of a rung ladder.
- the spar is designed as a hollow profile, in particular 3 can also be seen.
- a ladder foot 11 is arranged with a profiled surface.
- a pull-out tip 12 projects over the ladder foot 11 secure anchoring of the ladder in the ground.
- the pull-out tip 12 is arranged in an interior of the spar 10 and guided from FIG. 3 guide 13.
- the Guide 13 is also a hollow profile part in which the pull-out tip 12 is slidably mounted and that with two rivets 19 is attached to the spar 10.
- the spar 10 has two locking openings 14, 15 for a locking projection 16 arranged on the pull-out tip 12 (Fig. 2, Fig. 3) in the form of a bolt with a rounded tip on.
- the locking projection 16 is through a spring 17 against that provided with two locking openings 14, 15 Spar pressed inside, whereby the bolt 16 through the Opening 15 comes out.
- the spars 10 have an inventive one Leader in the area of the lower bar ends apart from that Bolt 16 no outwardly projecting parts for guidance and Actuation of the pull-out tips 12 on.
- the handling of the ladder is therefore by guiding the pull-out tip 12 in none Way hindered, and the ladder has a more elegant overall Look on as ladders with on the spars from the outside attached guides for the pull-out tips.
