Definitions

  • the invention relates to a vertical ladder made of metal, which can be detachably assembled from two mutually supporting conductor parts, recesses for receiving support means being provided at the upper end of the other conductor part in the upper region of one conductor part.
  • Such ladders are generally known.
  • the two conductor parts can be used separately or can be combined to form a double-sided conductor, the conductor parts supporting each other.
  • Such ladders are mainly made of aluminum today. During production, burrs or sharp edges occur on the recesses in the ladder stiles. If the part of the ladder having the recesses is used alone, the fingers of the person climbing the ladder usually enclose the ladder stiles. This person can easily injure themselves on the ridges or sharp edges of the recesses.
  • the object of the invention is therefore to protect the user of a fixed ladder of the type mentioned at the outset from the injuries described.
  • the caps cover the recesses.
  • the user's fingers now grip the cap, which is expediently provided with rounded edges, and can no longer be injured.
  • the caps are removed, but these are held on the conductor part so that they cannot be lost.
  • caps in the recesses in a press fit and to provide them with a band which can be fastened to the ladder and on which they stick to the ladder when they are removed from the recesses.
  • the caps are slidably attached to the ladder stiles.
  • An embodiment can be designed in such a way that the caps on the ladder bars are arranged so as to be transversely displaceable, the caps thus moving in the latching direction of the support means of the other ladder part and being brought back into the position covering the recesses, for example by spring force when the other ladder part is released.
  • the cap is arranged to be longitudinally displaceable on the ladder bars. The gravity of the cap can then be used to bring the cap into the cover position.
  • Fig. 1 the upper part of a ladder stile 1 with a ladder rung part 2 and a rubber cap 3 arranged at the upper end of the ladder is shown in plan view.
  • the other ladder stile of the vertical ladder is not shown and is designed accordingly.
  • the ladder bar 1 is provided with a recess 4, the elongated shape of which tapering inwards can be seen from FIG. 2.
  • the recess 4 serves to receive support means, not shown, of the other conductor part of a double-sided ladder.
  • These support means can be a round rod, which is fastened at the end of the other conductor part between their spars, or round stub axles, which are fastened to the spar ends of the other conductor part. After inserting such support means into the recess 4, the other ladder part is secured to the ladder bar 1 in a manner not shown.
  • a cap 5 is shown above the recess 4 in a position that releases this recess.
  • the cap 5 made of plastic or metal is U-shaped in cross-section with two side legs 6, 7 and one connecting these side legs Intermediate piece 8 and positively adapted to the spar shape.
  • the side legs 6, 7 are dimensioned such that the recess 4 can be covered.
  • the intermediate piece 8 has an elongated hole 9 running in the longitudinal direction of the conductor, through which a bolt 10, which is fastened to the stile 1 above the recess 4 and which holds the cap 5 with its bolt head, is guided.
  • the intermediate piece 8 is further provided at the upper end and at the lower end with handles 11, 12 in the form of beads. Furthermore, the intermediate piece 8 carries two arrow representations 13, 14, which are formed in particular by the material of the intermediate piece 8 and indicate the directions in which the cap 5 can be moved. From Fig. 2 it can be seen that these arrow representations are raised. The edges of the cap are rounded.
  • the cap is preferably a plastic injection molded part.
  • the cap 5 is shifted downward so that it covers the recess 4. After the other conductor part has been removed, this displacement can preferably take place due to the weight of the cap 5. However, a friction fit of the cap 5 can also be selected so that it must be moved into the cover position by hand.
  • the opening 4 can be opened by moving the cap 5 upwards by means of the other conductor part, this conductor part attaching to the lower handle 12. The recess 4 is thus covered with simple means.
  • the recess 4 is covered. The user can no longer injure himself on the edges of this recess.
