Definitions

  • the invention relates to telescopic guide rails of inclined or scaffold lifts with slidably guided, extruded, in cross-section approximately U-shaped profiles of different sizes, preferably made of Al Zn Mg 1 F36 with perpendicular to the profile web, the U-legs forming profile flanges, wherein the inner profile has the smallest cross-section and two single legs of the same width and thickness and leads with a single leg on a double leg of the next profile, all profiles following the inner profile increasingly larger cross-section have a single leg and a double leg and the inner profile and if necessary several profiles of increasingly larger cross-section following this profile have a web of constant thickness and, where appropriate, a profile has a web of increasingly greater web thickness which tapers conically from the single flange to the double flange, and the one do Profiles with a pile leg lead with a thinner, outer leg 2 to a thicker, inner leg of the next outer U-profile.
  • Such inclined or scaffold lifts are known, in each of which two of the above-described profiles of the same cross-section are connected to one another by rungs, so that they form mutually guided conductors whose U-profiles form the guide rails for load platforms or the like which can be moved thereon.
  • Telescopic guide rails of the type described above belong to the standard d. T. the applicant. They correspond to the representation according to FIG. 1.
  • the double legs are of approximately the same length and the webs of the individual profiles are in direct contact with one another. It can be seen that, in relation to the (upper) single leg, a significantly greater accumulation of material takes place in the region of the double leg.
  • the invention is based on the object that d. T. to eliminate the disadvantages described above, i.e. in particular to ensure that in addition to an optimal design of the individual profile - in particular with regard to the prevention of undesired distortion during extrusion - the inclined or scaffold elevator is designed in its overall structure in such a way that the profiles which are guided into one another are arranged in such a way that optimal sliding properties connected with optimal load transfer.
  • the invention is based on the consideration that the telescopic guide rails for inclined or scaffold lifts must be able to be put together to form different "kits" - for example depending on the required load capacity, the maximum extension length or the ability to bend the last (upper) guide rail.
  • the invention solves this problem in telescopic guide rails of the type mentioned by the features of claim 1.
  • the load from the lower, wider leg of a profile can advantageously be reduced to the thicker, shorter web of the next profile.
  • This power transmission is favored by the features b and c, according to which a profile-reinforcing wear bead is provided in particular in the vicinity of this narrower, thicker inner leg of the double leg, so that the force deposited on the narrower, thicker leg is optimally derived into the web.
  • the wear bead serves as a defined guide on the inner wall of the next outer profile, so that defined wear surfaces are realized.
  • the "free space" formed between the upper and the lower wear bead has the advantage that production-related or operational distortions can narrow this "free space", but that there are no longer any practical material interferences in this area between the adjacent webs of two guide rails . Since the guide rails are at least approximately vertical in the operating situation Arranged upright, dirt that has penetrated between the guide rails can escape downwards through this free space.
  • the arrangement of the wear beads according to the invention and the resulting material reinforcement at critical points as well as the free space thereby created between the beads are not (yet) necessary for the inner profiles because the web heights are (still) so low that both production-related and operational there are no excessively disturbing faults. Self-defined guide surfaces are given here by the low web height.
  • the special design of the seventh profile according to claim 2 is based on the fact that, taking into account the telescopic lengths of the individual guide rails that are common in practice and the necessary load capacity, the seventh profile is advantageously reinforced in the lower region compared to the other profiles, so that the guide rails One to six forces introduced can be optimally transmitted via the guide rail seven into the chassis of the inclined elevator or scaffold elevator.
  • the particularly reinforced design of the seventh profile in the lower area favors the connection with corresponding connection plates.
  • the invention is based on a kit with a maximum of nine guide rails.
  • the teaching of claim 3 conveys in detail the training of the guide rail belonging to this kit.
  • the combination of the inner five guide rails (1-5) is suitable for roofer elevators, the inner guide section being designed to be kinked.
  • the combination of the guide rails 2-6 is also suitable for roofer lifts, but can advantageously also be used for the transport of furniture, the last rail 2 in this case generally not being designed to be kinked.
  • the combination of the guide rails 3-7 is primarily intended for the transport of furniture, for example for a load of 400 kg, the last guide rail 3 in this case not being able to be bent.
  • kits from the rails 3-8 or 4-9 is preferably intended for rescue lifts and the like.
  • the telescopic guide rails according to the invention can be used equally advantageously in different types of elevators, such as construction elevators and the like.
  • the known profile arrangement can be seen from FIG. It can be seen that the two legs of the double legs are of approximately the same length and that the webs of the individual guide rails abut one another in the operating situation in such a way that no defined guide surfaces are provided. Flaws in the area of the double legs can lead to an undefined support of a profile on the following profile.
  • the inclined or scaffold elevator designated 1 has seven mutually guided U-shaped profiles, which were designated ag.
  • the inner profile a has a web 5 with two equal length, designated 4 profile legs.
  • the profiles bg adjoining this on the outside all have a single leg 14 which, like the single leg 4, serves as a guide (roller guide) for one Flatbed truck or the like. Serves, as well as double legs 2, 3 arranged at a distance therefrom.
  • the wider, thinner outer leg 2 leads to the narrower, thicker inner leg 3 of the next profile. It can be seen that a good introduction of force into the legs 3 is provided because the wider, thinner outer leg is supported on the thicker leg 3 approximately in the region of the apex between the leg and the web.
  • Both the double leg with the associated wear bead and the respective associated single leg have approximately the same amount of material, which is achieved in that the increasing length of the single leg with increasing profile increases the thickness of the wear bead S and a thicker version of the Leg 3 is compensated.
  • the webs 5-10 can have approximately constant material thickness. It has proven to be advantageous to form the ratio of the width B of the outer leg 2 to the width B 'of the inner leg 3 approximately as 2: 1, preferably as 41 mm: 21 mm.
  • the flange thickness D 'of the outer leg 2 relates to the flange thickness D "of the inner leg 3 approximately as 2: 3, in the illustrated embodiment as 5mm: 6mm.
  • the scaffold elevator is formed from the profiles a-e; this is regularly an inclined elevator for roofing operations, because for this purpose the inner profile a must be designed to be bendable, for which purpose a profile with top and bottom single legs is advantageously suitable.
  • this inner profile is missing;
  • this elevator is - if necessary also with a bendable profile b - suitable for the roofing trade, but is preferably also used for the transport of furniture on inclined elevators which do not require an upper bendable rail.
  • the profile g which is provided with a conically extending web 11, is assigned on the outside further profiles which have a web running in parallel.
  • These kits are special lifts, for example rescue lifts and the like, in which the inner profile no longer has to be designed to be bent.
