Definitions

  • the aim of the present invention is to remedy these drawbacks and to this end relates to a connecting device intended to make the angle formed by two elements connected by a pivot undeformable, said device being characterized in that said connecting bar is provided with its free end of a transverse notch allowing the attachment of the bar on a male part projecting from the other element, and in that on the connecting bar is mounted a slide having at one of its ends a notch which, when the slide is moved towards the free end of the bar, comes into engagement with said male part, thus preventing the bar from being raised.
  • said notch is constituted by a notch which extends in the direction perpendicular to the notch of the connecting bar.
  • the slider has a cutout over the entire upper part of its end, and has a spout at the lower part of said end which, when the slider is in its locked position, opposes movement towards the top of the link bar.
  • the slide is pierced with an elongated light extending in the longitudinal direction and in which is included a projecting element integral with the connecting bar, for example a screw, a bolt, a rivet or a boss obtained by deformation of the material of the bar.
  • a projecting element integral with the connecting bar for example a screw, a bolt, a rivet or a boss obtained by deformation of the material of the bar.
  • the double ladder comprises two planes 10, 12 articulated at their upper end by a pivot 14.
  • a connecting bar 16 articulated at 18, by one end, on one of the planes.
  • the link bar is shown in Figure 2 as a flat strip, but it can have any other shape of section, for example square or round.
  • the connecting bar On its lower edge and in the vicinity of its free end, the connecting bar is provided with a notch 20 with a concavity facing downwards. Once the planes open at their normal angle of use, they are immobilized by lowering the connecting bar so that the notch 20 hooks onto a male part 22 fixed on the other element 12.
  • the male part 22 can be formed by a rivet fixed in the wall thickness of the upright 12, but it can also be formed by any equivalent mechanical means.
  • a tubular slide 24 of the same inner section as the bar is fitted on the connecting bar.
  • the slide is notched at the end of its two parallel walls which are in contact with the flat faces of the bar, on the side of the notch 20, of notches 26 extending in the longitudinal direction of the connecting bar.
  • the notches 20 and 26 intersect, defining between them a passage of section slightly greater than that of the rivet 22.
  • the bar 16 is hooked onto the rivet, then the slide 24 is slid to the right in FIG. 2 until its notches 26 grip the rivet.
  • the link bar can no longer be raised accidentally.
  • the stroke of the slider is limited by a piece 28 integral with the connecting bar and which projects through an elongated opening 30 pierced in the slider.
  • the slide of Figure 4 differs from that of Figure 2 by the fact that it has at its end near the notch 20, over its entire upper part, a cutout 38 which defines on the lower part of the slide a beak 40. It is clear that when the slide is in its locked position, the male part is both in the notch 20 and in abutment in the angle formed between the cutout 38 and the spout 40. The latter is opposed to the upward movement of the connecting bar 16.
  • the slide 24 has at the entrance of its notches 26 one or two notches 32 which slightly narrow the width of said notches. To pass the redents on the rivet 22, the slide must be slightly forced. Accidental return of the slide to its unlocked position is absolutely impossible.
  • the slider can integrate on its outer wall reliefs 34 which allow a good grip and facilitate the movement of the slider on the connecting bar.
  • Such reliefs can also be formed on the slides of FIGS. 2 and 4.
