Definitions

  • French patent n ° 1.246304 describing a metal trestle with retractable feet and automatic opening under the action of a spring.
  • French patent n ° 2.487722 describing a folding trestle made up of two bent tubes, articulated around an axis and blocking them simultaneously with the opening.
  • French patent n ° 2.291329 describing a trestle made up of a vertical frame on which are articulated struts acting as feet, kept apart by connecting rods themselves articulated.
  • French patent n ° 2.220661 describes a trestle whose feet can be folded outwardly along the crossbar.
  • French patent n ° 2.418062 describing a removable trestle in separate elements.
  • French patent n ° 2.395112 describing a non-folding trestle equipped with casters and able to receive a bin.
  • Patent n ° 2.404722 addition to patent n ° 73.09643 describing a trestle, the feet of which can be dismantled and can be fitted into boxes secured to the crosspiece.
  • French patent n ° 1.504664 describes a telescopic trestle with claw.
  • French patent n ° 2.454877 describes a trestle whose articulated feet wedge a crosspiece.
  • US patent n ° 84/03347 describes a work easel whose feet are removable and held by straps during transport.
  • French patent n ° 2.389351 describes a folding easel made up of tubular frames hinged together.
  • French patent n ° 2.515242 describes a hinge for a trestle made up of two articulated frames.
  • French patent n ° 2.478782 describes a removable metal trestle.
  • French patent n ° 2.439931 describes a trestle whose legs are foldable.
  • French patent n ° 2.221033 describes a safety hinge for a folding trestle.
  • the present invention aims to bring improvements to these different models of easels, so as to facilitate their storage and transport, to simplify their deployment during installation for use and to increase their rigidity and stability in this working position.
  • the first improvement obtained resides in the fact that the feet fold inside the U-shaped cross member and, therefore, completely disappear, thus producing a compact product.
  • the second improvement concerns the deployment of the feet whose execution is simple and fast thanks to the combined compasses. Indeed, a blocking action exerted on the part of the compass acting as a strut makes it possible to simultaneously ensure the transverse spacing and the blocking in position of the articulated feet.
  • Another improvement concerns the increase in rigidity and stability of the feet in the deployed position, this thanks to an axis acting as a stop, thus limiting the opening of the feet and opposing the thrust exerted by the part of the compass acting of a strut.
  • the transport and the storage are facilitated by a fourth improvement which makes it possible to join face to face the pair of easels, joining obtained by means of a spring coming to engage, because of its elasticity, around a pin.
  • the pair of easels thus paired can be easily stored, the whole taking the form of a tube of rectangular section. Manual transport is then very easy thanks to a handle secured to a U profile wing constituting the crosspiece of one of the easels.
  • One end is articulated on the cross member 1 around an axis 16. This point of articulation is located in the axis of symmetry of the cross member 1.
  • the other end of the same part 8 of the compass is articulated on an axis 17 carried by a bracket 7, itself articulated on the part 3 of the compass around the axis 18.
  • part 3 of the compass articulated in its middle around the axis 18, is also at each of its ends, on the foot 6 around the axis 19 on the foot 2 around the axis 20.
  • the locking and spacing of the feet 2 and 6 is obtained by exerting manual pressure, from top to bottom, in the area of the axis 21 of the part 8 of the compass (FIG. 4).
  • the vertical manual pushing action on the axis 21 of the part 8 of the compass causes the deployment of said compass, simultaneously causing a reaction force of the axis 16, forcing feet 2 and 6 to pivot around the axis 4 to come into abutment on an axis 5 limiting the pivoting.
  • the part 8 of the compass then arcs around its axis 21 cooperating with a stop 9, in order to obtain a blocking giving great rigidity and stability to the bridge in the working position.
  • FIG. 6 represents the feet 2 and 6 articulated around the axis 4 secured to the cross-member 1.
  • the legs 2 and 6 deployed take an oblique position thanks to oblong holes made in the longitudinal direction in the said feet crossed by the axis 4 ( Figure 6 A).
