Definitions

  • the invention relates to a device for connecting two single-spar ladder elements, each having a central spar and a number of steps.
  • assembly ladders with fall arrest guide rails are used, which are temporarily suspended, screwed on or connected to the structure (DE-U-81 22 295).
  • the conductor elements have two side rails, between which a number of steps are arranged. Tongues protrude from the upper ends of the spars, onto which the next conductor element is attached.
  • the connection of the individual conductor elements is largely rigid.
  • the invention has for its object to provide a device for connecting two conductor elements, which has sufficient mobility both in the lateral direction as well as forwards and backwards, so that the assembly ladder formed from the individual conductor elements movements of a structure, e.g. of a pipe mast standing on an unstable surface.
  • this object is achieved in that a tongue is arranged at the end of one conductor element and coupling plates are arranged at the end of the other conductor element, which form a gap between them for receiving the tongue.
  • the tongue can preferably be fixed in the gap with a play of approximately 3 °.
  • the tongue is arranged on the back of the central spar, points in the direction of the central spar and forms the coupling plates have a narrowing gap between them in the direction of insertion.
  • the tongue is preferably secured in the gap of the coupling plates by a locking bolt extending transversely to the coupling plates, the locking bolt latching into a bore in the tongue.
  • the tongue and the two coupling plates are each welded onto plates which are screwed onto the back of the central spar.
  • the two conductor elements can be tilted against one another by approximately 3 ° forwards and backwards and to the side, without there being any tension at the joint between the conductor elements or on the fastening devices.
  • the tongue is normally on the lower conductor element and the coupling plates are arranged on the upper conductor element. However, an inverted arrangement is also possible.
  • a spring-loaded locking pin is expediently provided at the upper end of the lower conductor element to prevent the accompanying catching device from being inadvertently moved out.
  • Fig. 1 shows the two conductor elements at a distance from each other
  • Fig. 2 shows the two conductor elements in the connected state.
  • a lower conductor element 10 and an upper conductor element 12 each have a central spar 14 and steps 16.
  • the central spars 14 have a C profile which is open to the front, as is described in DE-C-1 961 757, DE-A-27 36 037 and EP-A-0 129 241 is known.
  • the central spar 14 also serves as a guide rail of a safety gear on which the user of the ladder is secured.
  • a plate 18 is screwed onto the rear side, which protrudes slightly beyond the blunt end of the lower conductor element 10 and on which a tongue 20 is welded, pointing at right angles and towards the rear.
  • the tongue 20 lies in a plane which is defined by the longitudinal axis of the central spar 14.
  • the tongue 20 has a flat 22 at the upper end and a bore 24 in the upper region.
  • a plate 26 is also screwed to the rear, which is set back from the end of the upper conductor element 12 by the amount by which the plate 18 projects beyond the upper end of the lower conductor element 10.
  • two coupling plates 28 are welded to the plate 26, the lower halves of which are angled away from one another, so that they form a gap 30 which opens downwards between them.
  • a spring-loaded locking pin 32 is attached to the side of one of the coupling plates 28 and is pressed into a securing position in the gap 30 by means of a spring (not shown in detail). Due to the flattening 22 on the tongue 20, the locking pin 32 is pressed back into the gap 30 when the tongue 20 is inserted. As soon as the tongue 20 has reached its end position in the gap 30, at which the ends of the lower and upper conductor elements 10, 12 abut, the locking bolt 32 engages in the bore 24.
  • the ends of the conductor elements 10, 12 butt against one another and the tongue 20 lies in the gap 30, the locking bolt 32 engaging in the bore 24 of the tongue 20.
  • the play of the tongue 20 in the gap 30 is selected in relation to the length of the gap 30 such that an inclination of about 3 ° to the front and back and to the side is possible is without tension occurring at the connection point.
  • a spring-loaded latching bolt 36 is provided on the plate 18 below the tongue 20, which is intended to prevent the accompanying catching device from inadvertently moving out.

Abstract

L'invention concerne un dispositif permettant d'assembler deux éléments d'échelle à un seul montant (10, 12) dont chacun comporte un montant médian (14) et un nombre de barreaux (16) . Ce dispositif contient une lame (20) montée à l'extrémité d'un des éléments d'échelle (10) et des tôles d'accouplement (28) disposées à l'extrémité de l'autre élément d'échelle (12) et qui forment un espace (30) entre elles pour loger la lame (20). La lame (20) peut être montée sur la face arrière du montant médian (14) et se trouver dans un plan défini par l'axe longitudinal du montant médian (14). La fente (30) peut se rétrécir entre les tôles d'accouplement (28) dans le sens d'insertion. Un boulon d'arrêt (32) monté sur ressort peut s'encliqueter dans la fente (30), sur la lame (20), lorsque cette dernière est en position finale. La lame (20) peut être fixée sur une plaque (18) pouvant elle-même être fixée sur le montant médian (14) et les tôles d'accouplement (28) peuvent être fixées sur une plaque (26) pouvant elle-même être fixée sur le montant médian de l'autre élément d'échelle (12).
