Definitions

  • the invention relates to an articulated bed base whose part bedding comprises a horizontal plane attached to a bed frame and to minus a tilting part hinged on the horizontal plane and maneuvered by at least one engine that modifies its inclination via a mechanism.
  • the bust part at least is pivotable relative to the sleeping surface.
  • the mechanism generally comprises at least one connecting rod powered by a motor.
  • a connecting rod powered by a motor.
  • This device comprises a rod articulated on the fixed frame of the bed base and in support by its opposite end on the reclining sleeping part.
  • the entire sleeping part moves in translation on the chassis fixed by means of a double lever articulated on the frame of the one end is hinged to the opposite end of the connecting rod.
  • the frame of the bed base is slidably mounted on a fixed frame, and the actuating motor carried by the fixed frame must provide a large effort at the beginning of the upward movement of the tilting part.
  • the object of the invention is to propose a mechanism for a bed articulated in which the horizontal plane is fixed relative to the chassis and in which the effort to be provided by the drive motor is low especially at the beginning of the upward movement of the tilting part.
  • the mechanism has at least one slide slidably mounted on the frame and actuated by the motor, said slider having a roller to cooperate with a cam integral with the tilting part during a part of the path of said slider, and at least one connecting rod of which one end is articulated on the tilting part and the other end has a sliding shoe mounted on the chassis and located in the path displacement of said slide, said pad being pushed by said slide during the other part of the path of the latter.
  • the slider When climbing the tilting part, the slider cooperates first with the cam, which allows a low rise of the tilting part for a consequent displacement of the slider, caused by a low engine effort. Then the slider comes into contact with the pad and moves the latter, the cam not cooperating with the roller, and the connecting rod taking over the cam to complete the movement of the tilting part.
  • the cam makes with the horizontal, an angle between 20 ° and 50 °, and preferably between 25 ° and 35 °.
  • the drawing shows the bust portion of an articulated bed 1 comprising a chassis 2 mounted on feet 3.
  • a slatted base including the central part 4, and possibly the part foot, defines a fixed horizontal plane.
  • a tilting portion 5 On the front end of the game central 4 is articulated a tilting portion 5, having to support the bust of a user.
  • the ends of the longitudinal members 6 of this tilting part are pivotally mounted about a transverse axis 7 on the ends rails 8 of the central part 4.
  • These longitudinal members 6 are equipped on their inner face and at the front of their transverse median plane of 9 wedge-shaped plates, which have under the plane defined by said longitudinal members 6 an oblique face 10, inclined approximately 30 ° to this plane, which extends upwards and towards the front of the bed 1 and whose function is to form a cam.
  • the longitudinal members 2a of the chassis 2 have on their faces side slides 2b designed to support each, so sliding, a slide or carriage 11.
  • the two carriages 11 are connected by a control bar 12 actuated in a known manner by a electric motor, not shown in the drawing, by means of a system drive type screw / nut for example.
  • Each carriage 11 comprises a roller 13 which can cooperate with the cam 10 during the movement of the carriage 11 along its spar 2a, especially at the beginning of the ascent of the tilting part 5.
  • the longitudinal members 6 of the tilting portion 4 are further connected to the longitudinal members 2a corresponding chassis 2 by a connecting rod 14, one end of which is articulated on the spar 6 at a location intermediate between the axis of pivoting 7 and the plate 9, and the other end has a skid 15 partially disposed in the slide 2b.
  • the rod 14 is recovering strongly during this second part of the rise of the reclining part 5 and the electric motor does not have need not to provide a great effort during this second phase of rise of the tilting part 5.
