Definitions
- the present invention relates to a ladder rung approximately rectangular cross-section and four forming a body Longitudinal outer surfaces, each perpendicular to the neighboring one Stand longitudinal outer surface, the one forming the tread surface Longitudinal outer surface of the ladder rung through from the plane of the Outstanding areas to prevent slipping along the longitudinal outer surface is profiled.
- the well-known ladder rung is the one that forms the step surface Longitudinal outer surface with a corrugation to a Form anti-skid.
- the well-known ladder rung has outside an approximately rectangular outline, but has an inside Cross section circular cavity.
- the object of the present invention is a Ladder rungs of the type mentioned above are available make that in a particularly simple inexpensive way can be produced and at the same time an effective Has anti-slip.
- An object of the invention provides the solution to this problem Ladder rung of the type mentioned at the beginning with the characteristic features of the main claim.
- the outstanding Areas of profiling that oppose the tread Secure slipping preferably in rows Nubs are formed, each between the individual Knobs deeper gaps are arranged.
- the Ladder rung initially in with the manufacturing process Longitudinal continuous longitudinal ribs is profiled or but is also extruded. Is the profiling through Forming is provided, for example, in the rolling process assumed a flat material, which after completion of the Profiling process is welded. In both cases, that is both in manufacturing by profiling as well optionally by extrusion, you can then preferably by embossing in the transverse direction Create gaps between the knobs. You have one particularly simple manufacturing process, which leads to a Ladder rung with high stability and comparatively thin Material thickness leads through the raised knobs effective on one or more of the longitudinal outer surfaces Has anti-slip, which slips off the foot, which the Prevents people using the ladder.
- the manufacture can automated for example in a rolling mill and is particularly economical in this respect.
- FIGS. 1 and 2 The illustration is schematically simplified and shown in principle just a section of a ladder rung, the Attachment to the ladder is not shown and the of course different lengths or diameters can have.
- the ladder rung according to the invention has four Longitudinal outer surfaces 1, 2, 3, 4, which in principle are rectangular Form basic shape in outline, although in the Corner areas the rectangle profile is rounded.
- the top longitudinal outer surface 2 is, for example Tread. In the exemplary embodiment, however, all are four Longitudinal outer surfaces 1, 2, 3, 4 each with a cross section preferably rectangular knobs 5 provided. These pimples are preferably arranged in longitudinal rows with 6, 7, 8, 9, 10 are designated.
- knobs 5 formed by the original longitudinal ribs 12th stop and the spaces 11 between them have (see Fig. 1). 3 to 5 you can see the Formation of the ladder rung according to the invention even more precisely detect.
- the longitudinal section through the profile of the ladder rung 4 is placed through a longitudinal row of knobs 5. So in principle it was due to an original longitudinal rib 12 cut. 4 shows the knobs 5 and between these intermediate spaces 11. Recognized in Fig. 5 one that several rows of knobs 5 lie side by side and that the individual knobs have an approximately trapezoidal shape can be trained. Between the different parallel spaced longitudinal rows 6, 7, 8, 9, 10 with Nubs 5 are intermediate rows 13, so that the nubs 5 compared to these smooth areas of the intermediate rows 13 are sublime.
