Definitions

  • the invention relates to a ladder according to the preamble of claim 1.
  • the problem to be solved is to provide a conductor of the type mentioned, whose stability is further improved and the risk of accidents is further reduced.
  • a cross member which has on both sides each have an opening into which openings the support rods with their lower ends can be inserted, the support rod ends to improve the stability with to penetrate into the soil certain tips are provided, are housed in the openings when not in use and in particular when handling the ladder is no risk of accidents.
  • the ladder according to the Fig. 1 and 2 is designed as a step ladder.
  • the spars are connected in the usual way with sprouts 2.
  • the two ladder parts of the ladder are hinged to a pivot pin 3.
  • one of the ladders is provided with an upwardly extendable pull-out ladder 4 according to the double arrow.
  • In the upper rail area is located on the bars 1 on both sides ever a joint 5, of the depending on a support rod 6 protrudes laterally. These support rods 6 are telescopically extendable and fixable in the respective desired extension position.
  • the rods are infinitely lockable by a quick release.
  • the fixation of the respective extension position of the support rods 7 can be done in a conventional manner by mutual rotation of the rod parts, by clamping sleeves or the like.
  • the lower rod end is provided with tips 6, which are intended to penetrate into the soil.
  • the joint 5 is movable in several planes, for example in the form of a universal joint or as a ball joint and connected to the support rods 7.
  • the support rods 7 - based on the conductor level - are widely spread and secured by the tips 6 on the ground.
  • the support rods 7 When not in use, the support rods 7 can be inserted by retaining means in openings of a cross member 9 at the lower end of the conductor.
  • the support bars can be used both with buckled ladders and with free-standing ladders, possibly with extension ladders. Since the support rods are telescopically variable in length, the expansion position can be easily adapted to the particular terrain conditions. For terrain inclinations, the extension position of the two support rods 7 may also be different.
  • the provided with the aforementioned support rods 7 ladders result in a significantly increased stability and thus reduced risk of accidents.

Claims (5)

  1. Echelle comportant au moins deux montants (1) et des échelons (2) disposés entre, avec respectivement une béquille (7) fixée de part et d'autre dans la zone supérieure d'une paire de montants par le biais d'une articulation (5), lesquelles béquilles (7) pouvant être réglées individuellement en longueur de manière télescopique sont destinées à soutenir latéralement l'échelle au niveau du sol dans sa position déployée et peuvent être bloquées dans la position déployée souhaitée, des moyens de retenue pour loger les béquilles (7) étant présents lorsqu'elles ne sont pas utilisées, caractérisée en ce que
    se trouve au niveau du pied de l'échelle, comme moyen de retenue pour loger les béquilles (7), une entretoise (9), laquelle présente respectivement des deux côtés une ouverture (8), ouvertures (8) dans lesquelles peuvent être introduites les béquilles (7) avec leurs extrémités inférieures dotées de pointes (6).
  2. Echelle selon la revendication 1, caractérisée en ce que l'articulation (5) est réalisée sous forme de joint de cardan ou sous forme de joint à rotule.
  3. Echelle selon la revendication 1 ou 2, caractérisée en ce que les béquilles (4) sont réalisées en forme de tube et le blocage des éléments tubulaires en prises l'un dans l'autre de manière télescopique s'effectue par une rotation de l'un des éléments tubulaires, ce qui permet ainsi un blocage continu.
  4. Echelle selon l'une quelconque des revendications 1 à 3, caractérisée en ce qu'elle est une échelle double.
  5. Echelle selon l'une quelconque des revendications 1 à 3, caractérisée en ce qu'elle est une échelle télescopique.
