Definitions

  • the present invention relates to a table with central extension.
  • extension table systems there may be mentioned, among others: the so-called Italian tables, with two extensions that can be retracted under the table top or brought in the extension of the two ends of this table; and the tables with central extension, comprising above a chassis two mobile trays capable of being brought together, so as to constitute by themselves a continuous surface, or to be symmetrically separated from one the other, or one independently of the other, so as to allow the establishment of the central extension between them.
  • Tables of the first type are illustrated for example by FR-A-2 261 726; those of the second type are by US-A-3,792,668.
  • the mechanism of the tables of the second type is currently constituted, for each of the two movable plates, by a set of four links, two parallel links connecting each side of the table to the frame of the table , so as to form a mobile structure of the "deformable parallelogram" type.
  • the 180 ° rotation of all the rods allows the trays to pass from the position of use without extension, in which they are adjacent, to the separated position allowing the installation of the central extension. It is understood that during this rotation, the two plates remain parallel to themselves, therefore in principle horizontal.
  • This known mechanism has the disadvantage, however, that if the table is lifted by its ends to be moved, it is the plates which are raised relative to the frame.
  • the present invention aims to remedy these drawbacks by providing a mechanism for a table with a central extension which, while remaining simple, prevents the trays from being raised when the table is grasped by its ends.
  • a mechanism for a table with a central extension which, while remaining simple, prevents the trays from being raised when the table is grasped by its ends.
  • each plate carries under its lower face, two parallel rails of U-shaped profile, fixed by one of their wings to said plate, each rail being able to slide and pivot relative to a roller mounted on a supported axis. by one end of the table frame and housed inside the rail profile.
  • the table shown in the drawing generally comprises a frame formed by four legs (1), two side members (2) and two cross members (3), chassis above which are mounted two symmetrical movable plates (4 and 5), between which a central extension (6) can be fitted.
  • Each of the plates (4 and 5) carries, under its lower face, two parallel rails (7), of longitudinal direction relative to the table, taking place between the two side members (2) of the table frame.
  • each rail (7) has a U-shaped profile, one wing of which is fixed under this plate (4 or 5), the bottom of this U-shaped profile being turned towards the corresponding spar (2). , that is to say outward.
  • Each rail (7) is extended towards the center of the table, by a part (8) of L-shaped section, which is connected to the corresponding beam (2) by means of a connecting rod (9).
  • (10) designates the axis of articulation of one end of the link (9) to the beam (2 and 11) designates the axis of articulation of the other end of the link (9) to the extension (8) rail (7), these two axes (10 and 11) being horizontal and parallel.
  • the two links (9) of the same plate (4 or 5) are located opposite.
  • Each beam (2) carries, at each of its ends, an axis (1-2) on which is mounted, free in rotation, a roller (13).
  • the axis (12) is for example mounted in a cleat (14) housed inside a U-shaped profile constituting the beam 2 (see Figure 4), the direction of this axis (12) being horizontal and perpendicular to that of the spar (2).
  • the roller (13) is housed inside the U-shaped profile of the corresponding rail (7).
  • Each plate (4 or 5) is thus spaced outwards, relative to its initial position, by a distance equal to twice the distance between the centers (10-11) of the links (9). In total, the two plates (4 and 5) are therefore spaced a distance equal to four times this center distance.
  • the extension (6) rectangular in shape and having a width equal to the spacing of the two plates (4 and 5), is placed in the empty central space located between these two plates, as illustrated in FIG. 7.
  • the invention applies to the production of transformable tables, both for indoor furniture and for garden furniture.
  • it is more particularly applied to an oval table, the two trays (4 and 5) having rounded outer edges, but it is understood that this characteristic remains independent of the invention and that the trays (4 and 5) could have another shape, for example simply rectangular.
  • the invention is not limited to the only embodiment of this table with central extension which has been described above by way of example, but it embraces it, on the contrary , all variants of implementation and application based on the same principle.
