Definitions

  • the invention relates to a ladder with a plank, the ladder being adjustable in length and having retractable and lockable support bars on the outer longitudinal sides, which are infinitely adjustable in length and designed to be pivotable in all directions and lockable by means of continuously adjustable tension and compression struts are.
  • a generic device is known from utility model DE 298 21 356 U1, in which stabilizing supports for fixed-ladder and mooring lines are described. Tension and compression struts are articulated in pairs in parallel on the long sides of a stabilizing support and can be folded out and folded out and locked.
  • the object of the invention is to develop the known ladder so that it can be used both as a conventional ladder and as a work floor or work platform.
  • the ladder can be used in a conventional manner in the opened state and as a work floorboard or work platform in the folded state.
  • a push-out contact ladder which can be converted into a fixed ladder by means of laterally positioned and swing-out support bars, and a length-adjustable working platform are combined in each case by two plate halves that can be folded in and out separately and are hinged to the ladder rungs .
  • the ladder board can be placed horizontally on one side, even on steps in stair curvatures, made possible by the differently adjustable ladder bar ends. The other side can be adjusted to the stair heights using the continuously adjustable support bars.
  • the ladder board is particularly easy to transpose or store, but is always ready for use as a single ladder, step ladder or stair-climbing work platform.
  • Fig. 2 shows the ladder with a board with the panel halves opened
  • Fig. 4 shows a locking bolt with segment washer and compression spring
  • Fig. 5 shows in longitudinal section a ladder with a plank with the panel halves folded in, through the slot-shaped opening of which a rung hook is inserted and hooked into a ladder rung on the underside.
  • Hinges 5 are arranged on each outer longitudinal side of a platter half and are connected to the ladder rungs on the underside.
  • each of the plate halves 1 There are preferably two bores in each of the plate halves 1, through which locking bolts 3 are carried out with segment disks 12 and are secured from one side with a nut 11.
  • the length of the bolts is dimensioned only as long as is necessary to reach over the segment disc 12 over the outside of the ladder rail in order to lock the plate halves 1 in the opened state. Due to the one-sided center of gravity, the segment disk 12 always ensures that an opened panel half 1 is held securely when the ladder board is used as an erected single ladder or fixed ladder, even if the distance between the fastening nut and the inside of the segment disk is greater than the outside of the ladder rail.
  • the one-sided weight of the segment disc 12 and the associated rotation according to gravity requires a sufficient width or chord length of the segment disc in order to securely lock the unfolded plate halves in any contact situation of the conductors.
  • the locking bolt 3 By rotating the segment disc to the parallelism between the chord side of the segment disc and the upper side of the spar, the locking bolt 3 can be returned with the segment disc 12 and the plate half 1 can be folded in.
  • Length-adjustable ladder bars 4 are designed to reliably achieve uneven support widths (e.g. stair curvatures), regardless of the front or rear of the ladder.
  • At least one support bar 6 which can be swung out and infinitely adjustable in length and is also secured with infinitely adjustable tension / compression struts, is articulated and can be folded in and locked together with the tension / compression struts parallel to the exterior of the ladder.
  • the plate halves 1 of the first ladder In order to be able to hook the rung hooks 9 arranged in the lower ladder area of the second ladder onto the respective rung of the underside first ladder even with the plate halves 1 folded in, the plate halves 1 of the first ladder have slot-shaped openings 10 at the rung spacing through which the rung hooks 9 of the second ladder and hooked onto the rungs of the first ladder.
