Definitions

  • the present invention relates to a movement mechanism.
  • the present invention is advantageously used inside a sofa or a reclining armchair or the like provided with movable parts, such as a headrest/backrest or the like, to which the following description will make explicit reference without thereby losing generality, for moving such movable parts from a closed position to an extended open position (configuration of rest of the head of the user).
  • movable parts such as a headrest/backrest or the like
  • actuator means mounted directly in the supporting frame of the sofa or armchair and comprise actuator means, mechanically connected to the aforementioned quadrilateral articulated system at opposite lateral ends of said levers so as to move the aforesaid levers or arms to and from an extended open configuration, below the command of electric actuating means connected to the said actuator means.
  • the aforesaid actuator means are formed by pneumatic actuating cylinders (gas), each of which is mechanically connected to the aforementioned articulated quadrilateral system being disposed attached to a relative lateral portion of said system.
  • the main scope of the present invention is to provide an improved movement mechanism that eliminates considerable and serious problems linked to the safety of the user deriving from the dangers of cutting, crushing and / or shearing the upper limbs or hands of the user himself during the movement of the aforementioned moving parts.
  • Another scope of the present invention is to provide an improved movement mechanism which is simpler to construct and assemble, and furthermore such as not to compromise the aesthetic configuration of the sofa or chair on which it is mounted.
  • FIG. 1 shows in a lateral view an improved moving mechanism for moving parts movable parts of a reclining sofa or armchair or the like according to the present invention, shown in a closed position;
  • FIG. 1 is the perspective view of the mechanism of Figure 1 ;
  • Figure 3 shows in a lateral view the moving mechanism of Figure 1 , shown in an opened position
  • FIG. 4 is the perspective view of the mechanism of Figure 3;
  • Figure 5 shows in a front view the mechanism of Figure 1 ;
  • FIG. 6 is another perspective view of mechanism shown on Figure 1 ;
  • FIG. 7 is another perspective view of mechanism shown on Figure 3;
  • Figure 8 represents the mechanism of Figure 7 in a large scale
  • FIG. 9 shows a reclining sofa or armchair or the like with partially shown the improved moving mechanism of the present invention.
  • M indicates as a whole a movement mechanism for moving parts, for example a headrest/backrest H, of a reclining sofa D.
  • the mechanism M is of the substantially known quadrilateral shape type defined by a plurality of articulated arms pivoted to each other and mounted on a frame adapted to be mounted inside the sofa D.
  • Mechanism M comprises two longitudinal main members L1 and L2, substantially shaped like a flat plate or similar connected and fixed to three transversal bars BT1 , BT2 and BT3 so as to define a quadrilateral structure.
  • the transversal bar BT1 is placed upper in respect of bar BT2.
  • the longitudinal members L1 and L2 mount respective groups G1 and G2 of articulated movable arms B1 and B2 which are mutually spaced and connected through bars BT 1 and BT2 so as to form mobile supports J1 and J2 adapted to support a reclining headrest H of the sofa D.
  • transverse bars BT1 and BT3 of the frame T are provided, each in a perfectly central position of the bars BT 1 and BT3, of an anchorage and fixing point/seat for a respective end of an actuating cylinder AC.
  • the actuating cylinder CA is unique, it’s thus fixed and acting at a perfectly central position of the mechanism M itself, and is adapted, in use, to determine the movement of the cited articulated arms B1 and B2 so as to determine the movement of the headrest/backrest H from a closed position ( Figures 1 and 2) to a position extended open ( Figures 3 and 4) corresponding to configuration of rest of the head of the user of sofa D.
  • each abovementioned group G1 , G2 comprises the following structural elements:
  • said guide plate K1 , K2 being provided with hollow slit S1 , S2, wherein pins W1 and W2, fixed at one end to the large plate K1 , K2, are adapted to slide, said pins W1 and W2 being connected to a bar Y1 , Y2;
  • said bar Y1 , Y2 being mechanically connected to the transversal bar BT3 (and to support element J 1 , J2) by a couple of curved elements N1 and N2 pivoted each other;
  • spring means SM1 and SM2 are fixed, each, at both ends of the transverse bar BT3 and at one end of each large plate P1 , P2.
  • the activation of the AC actuator sets the groups G1 and G2 in motion so as to move the supports J1 and J2 to bring the headrest H from the closed rest position to the open extended position.
  • the spring means SM1 and SM2 of the groups G1 and G2 are suitable to allow the automatic return of safety towards the closed position in case of obstacles or hands of the user between the mobile arms B1 and B2 of said groups G1 and G2.
