Definitions

  • the invention relates to a ladder with a plank, the ladder being adjustable in length is formed and on the outer longitudinal sides of retractable and lockable support bars which is infinitely adjustable in length and by infinitely adjustable pull and Pressure struts can be swung out and locked in all directions.
  • a generic device is known from utility model DE 298 21 356 U1, in the stabilization supports for fixed and single ladders are described. Tension and compression struts are parallel in pairs on the long sides of a stabilizing support Folded in and out, hinged and designed to be lockable.
  • the object of the invention is to further develop the known ladder so that they can be used as a conventional ladder as well as a work floor or work platform can be used.
  • an extendable single ladder which is converted into a fixed ladder by means of support bars that are positioned laterally and can be swung out can be, and a length-adjustable work platform by two Separately foldable and foldable plate halves, which are articulated to the rung are united.
  • the ladder board is horizontal, even on steps in curved stairs to hang up safely with one side, made possible by the different adjustable handlebar ends. The other side can be adjusted by the continuously adjustable Adjust the support bars to the stair heights.
  • the ladder board is particularly easy to transport or to be stored, but at any time as a single ladder, step ladder or stair-climbing work platform ready for use.
  • the support bars can be replaced at the lower ends with replaceable rubber feet be provided with brake rollers or support foot plates with earth tips are.
  • Plate halves 1 On a ladder there are two juxtaposed on one surface side Plate halves 1. Each are on an outer long side of a plate half Hinges 5 arranged, which are connected to the ladder rungs on the underside.
  • the plate halves 1 there are preferably two bores through which Locking bolt 3 performed with segment washers 12 and from one side with a mother 11 are secured.
  • the length of the bolts is only as long as to reach over the segment disc 12 over the outside of the ladder stile is necessary to open the plate halves 1 Lock condition.
  • the segment disc 12 always ensures due to the one-sided center of gravity for a secure hold of an opened panel half 1 when using the ladder board as an upright ladder or step ladder, even if the distance between Fastening nut and segment niche inside is larger than the outside of the ladder stile.
  • the one-sided weight of the segment disc 12 and the associated rotation according to gravity requires a sufficient width or chord length the segmented disc, around the unfolded panel halves in any application situation to lock the ladder securely.
  • the locking washer 3 with the segment washer can be used for the segment washer and the upper side of the spar 12 returned and the plate half 1 can be folded.
  • Both ladder rails of the ladder are extendable and adjustable on both sides Ladder stiles 4 designed around uneven support widths (e.g. stair curvatures) safe to reach regardless of the front or back of the Ladder.
