Definitions

  • the present invention relates to a ladder according to the Preamble of claim 1.
  • a ladder is known in which the rungs are to be supported against rotation by means of screws or the like in the spars. Furthermore, from DE-A1-1 409 302 a ladder is known in which a rotation between the rung and spar is to be ensured via a tongue and groove connection. In both cases, with a longer alternating load, the connection between the rung and the spar can loosen; the existing assembly game can increase.
  • a rung In many cases, however, it is desirable to use the rung To give shape, which differs from a circular tube. Examples this can be seen from FR-OS 23 69 411. Often a rung is sought, whose outer diameter in the is essentially rectangular or square and the one flat Tread offers.
  • the working angle of ladders gives way in many cases clearly from the vertical, so that the tread at the desired horizontal extent must extend obliquely to the longitudinal axis of the spar, as is made Fig. 17 of FR 23 69 411 can be seen.
  • buck ladders can the tilt angle between the horizontal tread surface and the spar, for example, be about 30 °.
  • the invention has the object, a Ladder according to the preamble of claim 1 to provide also can be used universally without an increased risk of injury stocks, while still a secure rotation despite simple installation at low-cost production is guaranteed.
  • the conductor according to the invention initially has spars, the for the inclusion of sprouts according to the invention are suitable.
  • the spars on recessed areas are limited by edges, as the force transmission surfaces according to the invention can serve.
  • the rotation stops by notching the non-round Parts of the rung are made symmetrically. hereby can the applied torque evenly supported, so that they do not cause asymmetric loading of the shoot in the Holm leads, which is a relaxation of the rung / spar connection would favor.
  • the rotation stop chosen so that the rotation stop with minimal stiffness jumps the transition between sprouts end and Sprout forms.
  • the notch extends at an oblique angle to which then the edge the recessed portion of the spar is chosen appropriately.
  • the durability can be synonymous of alternating loads significantly increase underlying levels, and due to the symmetrical configuration of the stage, which basically Four rotation stops can have them symmetrically around them are distributed, so up and down and both sides against its axis of rotation, can be inventively equipped Use ladder universally.
  • the shoots in a circular tube ends with the least possible material stress can be flanged.
  • the invention Pipe can also be widened well to the strength of the Rung / spar connection especially for single-walled, ie C-spars, to be as big as possible.
  • the stability and Durability of the rung / spar connection dramatically increases.
  • the expansion circular make Rather, it has to be cheap pointed out, the expansion dull ever over a peripheral area for example, make 45 °, in which case, for example four expansions evenly around the circumference can be provided distributed.
  • Expansions of both the inner and the. are preferred provided adjacent outer spar wall.
  • the expansions preferably extend holminnen paragraph, so basically between the two spar walls and these closely adjacent. By this measure is a safe support of the rung in the spar at both tensile and compressive loads guaranteed.
  • a Stiffening of the spar ensures, and this combined with the recessed mounting of the bead.
  • the return dimension can be chosen practically so that the flare the
  • a conductor 10 according to the invention of which in Fig. 1 only a small section is shown, has a spar 12th and a rung 14. Extend in a conventional manner numerous sprouts 14 between Holmen 12.
  • the sprouts 14 Like the other rungs, it consists of an aluminum extruded section in the form shown in FIG. 1.
  • the Sprout has inside a cross section of a tube 16. At the upper and lower ends extend laterally wings 18, the width of the rung 14 increase significantly and at their top are provided with a corrugation 20.
  • These Design of a rung 14 increases the tread resistance of Ladder compared to a round rung in a very special way.
  • the wings 18 extend such that the top 22 of the rung is a slight waveform having.
  • the upper wings 18 are downwards and downwards the lower wings 18 are bent end up.
  • additional elements or substantially C-shaped impact protection profiles 24 made of plastic in the rungs added.
  • the impact protection profiles 24 in the Sprouts anchored before the rung / spar connection is made.
  • the shock protection profile 24 is slightly under tension, so that the impact protection profile slightly elastic springs or when Pressing is rolled in and a shock protection against the touch of the quite hard sprouts metal when Using the ladder makes.
  • any other suitable elements insertable are, for example, elements for hanging the ladder or similar.
  • a rungs / spar connection according to the invention 26 can be seen.
  • the rung 14 has over its almost entire Length of the apparent from Fig. 1 structure.
  • the wings 18 are removed, for example by notching or twisting.
  • the rung 14 remains as a tube 16 and is in corresponding recesses in the spar 12 inserted.
  • the inner spar wall 36 has a recessed Area 38, bounded by the power transmission surfaces or inclined surfaces 32 is.
  • the width of the recessed portion 38 is so designed so that they are substantially the outer diameter of the Tube 16 corresponds.
  • the inclined surfaces 32 and the stop surfaces 30th extend substantially at an angle of 45 ° Longitudinal axis of the rung 14.
  • the outer spar wall 40 has a recessed area 42 on.
  • the two recessed areas 38 and 42 Jump towards each other accordingly and rejuvenate the spar 12 in the middle.
  • In the recessed area 42 of the spar is from the end 28 of the rung pass through.
  • the sprout end 28 points there a bead 44 which the recessed portion 42 in essentials.
  • the bead 44 is mounted in such a way that the spar 12 between the bead 44 and the heels something is clamped. Furthermore, the rung 14 is at the Fig. 2 apparent points or widenings 46 widened slightly from the inside each adjacent to the wall 36 or 40 adjacent.
  • Fig. 3 is a perspective view of a corresponding Ladder 10 can be seen in detail.
  • the conductor 10 has in this embodiment, between spar 12 and rung 14 clamped, auxiliary elements 50 and 52 on, as a hook or as a guide element for the ladder 10th serve.
  • the auxiliary elements 50 have in the illustrated Embodiment on a profiling, the shape of the Holmwand 36 is adapted, so that the rotation of the Sprout 14 indirectly via the auxiliary element 50 and 52, respectively results, which is clamped between the spar and rung.
  • Fig. 4 is a modified embodiment of an inventive Sprouts / spar connection visible.
  • wings 18 extend significantly farther outward as in the embodiment according to Figures 1 to 3.
  • Sie are on their top 22 curled and then depending down folded.
  • the assembly in the spar 12 is done so that the Top 22 is slightly oblique to the longitudinal axis of the spar extends, so that this embodiment particularly for a Block ladder or other inclined ladder is suitable.
  • Fig. 5 From Fig. 5 it can be seen in which way the rung 14 in the spar 12 engages. Also in this embodiment is Sprout end 28 notched, taking the shape of the notch exactly adapted to the shape of the spar wall 36. Furthermore Ends 54 of the wings extend in corresponding indentations or undercuts 56 on the spar 12 and form an additional rotation stop on the spar 12, especially the distance between the ends 54 and the axis of rotation of the sprout end 28 is quite large.
  • FIG. 6 differs from this Embodiment in that the spar 12 widened a bit is, so that the ends 54 in grooves or undercuts 58 of the spar to run.
  • the inner spar wall 36 and the outer spar wall 40 formed symmetrically, so that a once optionally produced as an extruded beam profile is usable.
  • Fig. 7 is an enlarged view of another Embodiment of the rung / spar connection according to the invention seen.
  • the power transmission surface 32 interacts with the oblique paragraph 30 of the rung together, in such a way that these two surfaces always biased against each other.
  • the preload is not only due to the widening 46, but in particular also by the flanging 44, that of FIG. 2 can be seen, ensured.
