Definitions

  • Document FR-A-2 462 125 describes a device for blocking and balancing a work surface of a drawing table, supported by a central column sliding in a support comprising guide means and resting on a plate basic consisting of at least two brake pads diametrically opposite with respect to the geometric axis of the sliding column, constantly pressed by mechanical means against the inner surface of said column and by a gas spring supported by one of its ends on the base plate, by the other end, provided with a pulley, on a cable, characterized in that a safety device is constituted by a rocker whose pivot is fixed approximately halfway up the support of the column, one of the lever levers being crossed by a control rod for the brake shoes and carrying one of the cable hooking points, the other cable hooking point being located on the bottom of the column, l other lever of the basc ule being connected to a compensating spring having its tension point fixed on said support.
  • the safety device according to the invention is defined by claim 1.
  • the axle 141 of the pulley 14 rotates freely in a stirrup 16 fixed on the frame 1 near its base 2; it is only held in the bottom 161 of the stirrup 16 only by the tension of the cable 13. In the event of said cable breaking, the axle 141 leaves the stirrup by the effect of the weight of the pulley 14 since the the axis of symmetry AA of the stirrup 16 is vertical and that its opening 160 is oriented towards the base 2.
  • the support 151 of the pulley 15 is fixed on the frame 1 at the point furthest from the stirrup 16 compatible with the variation in height provided for positioning the work surface by sliding column 3.
  • the stirrup 16 has on the axis AA a guide 162 located at a distance from the axle (141) of the pulley 14, in place in the bottom 161 of the stirrup 16, determined by the width of the feeler 111 of the latch 11 and lower than this.
  • the widest part 112 comprises, opposite the probe 111, two recesses 110, 117 superimposed, one 110, the most distant from the linear base 113, in the form of a hook, receives one of the ends 100 of the rod 10 for controlling the permanent blocking means of the column, the brake 7, the other end 101 of the rod 10 being connected to the plate 8 for releasing said brake.
  • the other recess in the form of a notch 110 aligned on the axis of symmetry BB of the probe, receives a pin 600 fixed on the pedal 6, below the pivot points 601 thereof.
