Definitions

  • the present invention has for its object to provide a continuous terrain compensation without the disadvantages described, which requires only minimal intervention of the user to adjust and is safe.
  • an adaptation to sloping or uneven terrain without additionally carried devices or tools may be possible.
  • the device must be easy to manufacture.
  • the traverse is designed so long that it connects and is held by the spars, e.g. is pushed through breakthroughs in the bars.
  • the traverse is made short, so that it can be moved entirely between the bars.
  • Held the cross member in claim 2 of a guide device which is attached to the bottom rung and forms a kind of cage in which parts of the traverse can move laterally.
  • the legs do not necessarily consist of straight bars. It it must only be ensured that there is sufficient freedom of movement in the area of the leg guide.
  • the surfaces on which the traverse and its support or guide device touch influence the properties of the device. This fact will be taken up in the further remarks.
  • An arrangement with the mentioned properties can be produced, for example, simply from aluminum profiles in connection with some plastic moldings.
  • the height compensation is achieved in that the legs of the legs change their height when the suspension points are moved laterally.
  • the foot of the right leg undergoes a curve according to Fig. 1 (Control curve).
  • the curve for the left leg is obtained by mirroring the right leg trajectory, with one leg reaching its maximum height just when the other one has its minimum.
  • the exact course of the curves varies depending on the geometric conditions. From the control curve, taking into account further boundary conditions, such as the maximum desired leg steepness and the at least to be achieved stand broadening, a maximum height adjustment Y and the necessary adjustment X of the traverse are taken.
  • the device automatically adjusts the terrain compensation when wiping the ladder:
  • the too deep standing leg touches the ground and pushes the traverse both upwards and in the direction of the other leg on further weaning. This causes itself too low a stand up and the other base moves down, which is exactly what you want.
  • the ladder can only be lowered as far as the existing play allows. The traverse is now pressed by the weight of the ladder and because of the leverage on the legs against the lower guide surfaces.
  • the device can of course be adjusted by a displacement of the crossbar by hand.
  • the easy adjustability may possibly be improved by springs or a mechanism that pushes the crossbar in the unloaded state upwards.
  • the chosen variant of the device Fig. 2 is characterized by the fact that it also respects the side view Fig. 3 is perfectly symmetrical. It can be used in recesses on the undersides of the spars 1,2 .
  • the traverse 3 consists of a U-shaped rod, the holes for attachment of the axles for the legs 6,7 and screwed at the ends handles 4,5 , which simultaneously form stops for the adjustment of the traverse.
  • the crossbar of the crossbar may include a recess to facilitate adjustment by hand.
  • a corrugation is attached to the bottom, so that there is a particularly high static friction is achieved.
  • the brackets are corrugated in the region of the lower guide surfaces 13 , which, together with the corrugation on the cross member 3 causes the desired high static friction in the loaded state.
  • a rubber coating could be applied or a hard rubber part could be used.
  • legs 6,7 tubes can be used, which are provided for attachment in the upper part with a transverse bore and rounded so far that they can be pivoted after their assembly to the crossbar.
  • a pedestal 10, 11 is attached.
  • the axis therefore has a thread on the end faces.
  • the leg guides 8,9 consist of short, pivoting at the lower ends the home-mounted hollow-fiber rods, which are provided with sliding inserts FIGS.
  • the sliding inserts 16 can be glued or inserted. They may be provided at the ends with noses to prevent slipping.
  • the cross member 3 consists of a T-shaped rod whose transverse flange in a cage, which is formed of two riveted to the front and back of the lowest rung angle profiles 17, 18 , can be moved laterally .
  • the protruding from the cage web of Traverse is provided with holes for the axes of the legs 6,7 . Between the holes may still be a handle 4 may be attached to facilitate the displacement of the crosshead.
  • On the two lower sides of the flange 13, 14 of the traverse is a corrugation, mounted transversely to the direction of movement.
  • the inner sides of the angle profiles which form the cage for the traverse are also corrugated transversely to the direction of movement. At all other contact surfaces, in particular between the top of the traverse and the rung the lowest possible friction is desirable. This can possibly be promoted by a left and right on the crossbar mounted plastic shoe.
  • legs 6,7 tubes can be used, which are rounded for attachment in the upper part and provided with a transverse bore and a gap, so that the protruding from the cage web of the traverse inserted into the gap and connected to a transverse axis 15 can.
  • the axle is fixed from both sides with screws and washers.
  • additional molded plastic parts 19 may be embedded in the region of their suspension.
  • the leg guides 8,9 correspond to those of the first embodiment.
