Definitions

  • the present invention relates to a foldable stepladder.
  • the object of the present invention is to remedy these drawbacks.
  • the auxiliary uprights are articulated at one of their ends at the top of the main uprights and they are articulated together around an axis in their middle part to present in the deployed service position the shape of a cross, said auxiliary uprights being connected from said point of mutual articulation to the central upright by a link.
  • the opening of the stepladder is total and simultaneous during the opening of the auxiliary uprights by spreading the main uprights.
  • the stability is excellent the rear auxiliary uprights forming a three-branch triangulation with the spacer rod.
  • stepladder Since the stepladder does not require any locking, its opening and closing can be carried out in a single maneuver.
  • a stepladder according to the invention which comprises two main uprights 1 and 2, a central upright 3 and steps in two parts 4 and 5 which are each pivoted, of a part, on the main uprights around axes 6, 7, respectively perpendicular to the plane of the uprights main 1, 2 and in fact generally horizontal, on the other hand, on the central upright around axes 8, parallel to said axes 6 and 7,
  • the steps 4, 5 have in cross section a trapezoidal shape with a flat support part.
  • auxiliary uprights 14, 15 which rest on the ground by their other end 16, 17, said auxiliary uprights being articulated together in their middle part around an axis 18 to present in the deployed service position (Fig. 2) the shape of a cross.
  • the auxiliary uprights 14, 15 are connected from the articulation axis 18 by a link 19 to the central upright 3.
  • one of the ends of the link-19 is articulated around an axis 20 mounted on a yoke 21 itself articulated on the axis 18 of connection of the auxiliary uprights 14, 15, at its other end the link 19 is articulated on an axis 23 engaged on the central upright 3.
  • auxiliary uprights 14, 15 (FIG. 4, 5) on the upper part of the main uprights 1, 2 is carried out by means of hinges 24, 25.
  • Each hinge such as 24 has an axis 26 and two branches 27, 28 which are articulated respectively around an axis 29 on the main upright 1, 2 and around an axis 30 on the auxiliary upright 14, 15.
  • the axis 26 of the hinge 24, 25 is perpendicular to the axes 29 and 30 of articulation on the main upright 1, 2 and on the auxiliary upright 14, 15.
  • a cross member 32 is hinged around an axis 31 (Fig. 1, 2, 3) consisting of a U-shaped profile, the other end of which is removably attached to the upright 2 by means of a pin 33 connected to said upright by a chain 34.
  • the cross member 32 constitutes a gutter capable of supporting small objects and it reinforces the rigidity of the stepladder.
  • the device according to the invention operates in the following manner.
  • stepladder When the stepladder is in the folded position as shown in FIG. 1, it suffices to move the main uprights 1, 2 laterally apart from one another so that the two parts 4, 5 of the steps occupy a horizontal position service and that the two arms of the compass 11, 12 abut by their top against the central upright 3.
  • the spacer rod 19 with the auxiliary uprights 14, 15 form a triangulation with three branches which ensures excellent stability of the stepladder.
