Definitions

  • the present invention relates to a device for adjusting the angular position of a piece of furniture with respect to another piece on which it is articulated.
  • the present invention aims to remedy these drawbacks, by providing a simple adjustment device, offering rotational self-locking and therefore having complete safety, allowing fine adjustment, as well as complete disengagement to allow the furniture to be folded.
  • this device comprises, on the one hand, a part in the form of a long pitch twist which, integral with one of the two elements articulated one on the other, is oriented according to the 'axis of articulation of the two elements and, on the other hand, a nut which, engaged on the spin, of short length vis-à-vis that of the spin, and of section allowing its translation on the spin and its self-locking in rotation thereon, is blocked in rotation relative to the second element of the furniture considered, at least during the period of use thereof.
  • the two elements can consist of two pairs of crossed X-shaped legs hinged on each other, a pair of legs and the table top or the seat of a seat, or a backrest and the seat of a seat.
  • the table shown in Figures 1 to 3 includes two pairs feet in X articulated one on the other.
  • the first pair comprises two feet (2), relatively spaced from each other and braced by a piece (3) of square section, forming a long pitch spin.
  • the ends of the two feet (2) located on the side of the plate (4) are articulated thereon in yokes (5).
  • On the twisted cross member (3) is engaged a nut (6), of section corresponding substantially to that of the cross member, capable of translation along the latter, and of a self-locking in rotation.
  • On this nut (6) are fixed the two feet (7) constituting the second pair of feet.
  • This second pair of feet simply rests on the underside of the plate (4).
  • one end of the twisted part (3) has a significant thinning (8) of its section, allowing free rotation of the nut (6) at this level. This free rotation of the nut allows the table to be folded, as shown in Figure 3.
  • a first pair of feet (9) is braced by a twisted tube (10) of square section.
  • the feet (12) of the second pair of feet are connected, on the one hand, by a spacer (13) of circular section, housed inside the twisted tube (10) and, on the other hand, by a crosspiece (14) located at a certain distance from the crosspiece (13).
  • a nut (15) integral with a lug (16) On the twisted tube (10) is engaged a nut (15) integral with a lug (16), of length such that it can come to bear against the crosspiece (14) connecting the feet (12).
  • Figures 7 and 8 show two seats with X-shaped legs hinged on each other, which can implement one of the two adjustment systems described above.
  • the seat back (17) is integral with the seat (18).
  • the seat (18) is equipped with a crosspiece (19), or two coaxial fingers capable of bearing on the two feet (20) of the pair of feet not articulated on the seat.
  • the other pair of feet (22) is, for its part, articulated near the front of the seat.
  • Figure 7 shows this seat in the high position in solid lines, and in a lower position in broken lines, knowing that it is possible to make a continuous adjustment between these two positions.
  • the seat shown in Figure 8 differs from that of Figure 7 in that the backrest (17) is not integral with the seat (18), but the pair of feet (20) not articulated on the 'seated. Therefore, and as shown in the drawing, a change in the height of the seat also results in a change in the angle between the seat and the backrest.
  • Figure 9 of the drawing shows a seat in which the front feet (23) are articulated on the seat (24) independently of the rear feet (25), themselves articulated directly on the seat.
  • the backrest (26) is. for its part, articulated around a horizontal axis on the seat (24).
  • the two front feet (23) are connected at their upper end by a part (27) ensuring their pivoting in bearings (28). Between the bearings (28), the part (27) forms a square (29) having a long pitch twist. On this spin is engaged a nut (30) extended by a tab (32) bearing under the seat (24).
  • the adjustment of the inclination of the rear feet (25) is carried out in the same way, by means of a nut (33) extended by a lug (34) bearing under the seat, the nut (33) being engaged on a twisted part (35) belonging to the spacer connecting the two feet (25).
  • the backrest frame (26) is mounted, for its part, pivoting in bearings (36), between which is provided a twisted part (37).
  • a nut (38) is engaged on the twisted part (37), which is extended by a tab (39) bearing under the seat (24).
  • Figure 10 shows this seat in side view, in two positions.
  • Figure 11 is a side view, in two positions, of a variant of the seat of Figures 9 and 10, in which the feet are crossed but not articulated one on the other.
  • the tab (39) associated with the nut (38) for adjusting the inclination of the backrest (26) is constituted by a leaf spring, which gives great flexibility to the mounting.
  • the nut (38) for adjusting the inclination of the backrest (26) of a seat is equipped with an inner lining (40) of flexible material avoiding games between the nut and the twisted part (37) on which it is engaged, before a sufficient torque is exerted.
  • Figure 15 of the accompanying schematic drawing shows a variant of a nut (42) engaged on a twisted part (43).
  • This nut has an end (44) in the form of a fork, one of the branches of which forms a yoke (45) and the other branch of which has a rectangular opening (46).
  • the invention is not limited to the sole embodiments of this device for adjusting the angular position of two pieces of furniture, described above by way of examples; on the contrary, it embraces all of the variant embodiments and applications.
  • the spin could be constituted by two parts of circular section, arranged side by side, and on which is engaged a single nut having a section opening corresponding to the sum of the sections of the circular parts.
