Definitions

  • the present invention relates to the field of tables with a central extension of the type comprising a frame, two side plates, at least one of which is mounted to move relative to said frame, and at least one central extension capable of being positioned between the side plates, and more particularly a assembly of the tongue-groove type by recessing the extension with the side plates.
  • the main known extending tables are the so-called Italian tables, with two extensions that can be retracted under the table top or brought into the extension of the two ends of this top, and tables with central extension, comprising above of a chassis two mobile plates able to be moved closer to each other so as to constitute on their own a continuous surface or to be separated symmetrically from one another or one independently of the other, so as to allow the installation of the central extension between them.
  • the document FR2261726 describes an extending table, rectangular, square or at least having the two rectilinear, parallel and identical lateral sides, in which all the elements constituting it form an integral part of the frame of the table, characterized in that the two lateral sides of the frame of the table are at least of a height equal to the height of the main shelf or shelves plus the height of the extension shelf of the table, each of these two sides having on its inside face at least a rectilinear longitudinal guide path or notch as well as at least two vertical guide paths or notches placed parallel to each other in the shape of an inverted L, the length of the vertical branch of this L being at least equal to the height of the main shelf or shelves, the main shelf or shelves being provided laterally, like the extension shelf, with prominent elements such as pivots, teeth or ridges, capable of allowing the said shelves to be moved in the guide paths, elements whose dimension is a function of these said guide paths, the length of the longitudinal guide paths being sufficient to allow such movement, of the one or two main shelves, that the
  • the document FR1568723 describes a rectangular table, specially designed for the kitchen, with metal legs and frame and Formica veneered wood worktop.
  • the worktop consists of a fixed part and two extensions. These, in the closed position of the table, are housed under the fixed part, and in the open position of the table, develop on either side of the fixed part by means of carrying strips to come to the same level than the fixed part.
  • One of the aims of the invention is therefore to remedy these drawbacks by proposing a table with central extension of simple and inexpensive design, the extension(s) of which are removable and assembled in such a way that the top is perfectly aligned, even when the extension(s) or mobile tops become deformed.
  • a table with a central extension comprising a frame, two movable trays resting on said frame and able to be moved closer to each other so as to constitute to them only one continuous surface, or to be separated symmetrically from each other, or one independently of the other so as to allow the installation of one or more so-called central extensions between said movable plates;
  • said table is remarkable in that the fields of the movable plates and of the said extension or extensions comprise at least one tongue extending over a first half of said field and a groove extending over a second half of said field, said tongue having a height increasing from its distal edge to its central part and decreasing from its central part to its proximal edge, and the depth of the groove being greater than the height of the tongue even if the plates and/or the extension are deformed.
  • each tongue ensures, when the two movable plates are brought together after positioning at least one extension between the two movable plates, a progressive introduction of each of the tongues into the corresponding groove.
  • each tongue ensures a progressive deformation (and more precisely a progressive straightening) of the extension as said tongue is introduced into the corresponding groove, and thus obtaining a flat upper surface.
  • Such a configuration of the tongue also ensures, when the two movable plates are brought together in the absence of an extension between them, an insertion of the tongue provided on a first of the two movable plates in the groove provided on a second of the two movable plates and an insertion of the tongue provided on the second movable plate into the groove provided on the first movable plate, and therefore an assembly of the two movable plates and the obtaining of a flat upper surface
  • the tab has a length of between 30 and 50% of the length of the respective field, and for example between 40 and 50% of the length of the respective field.
  • the central part of the tongue has a length less than 20%, and preferably less than 10%, of the total length of the tongue.
  • the central part of the tongue is located in a plane which is perpendicular to the direction of extension of the tongue and which is located equidistant from the distal and proximal edges of the tongue.
  • the central part is located in the middle of the length of the tongue, that is to say in the center of the tongue.
  • the first tongue part extends as far as the second tongue part.
  • the edges of the tongue are bevelled and/or rounded.
  • the tongue comprises a recess opening into a top surface of the tongue.
  • the presence of such a recess ensures optimum centering of the extension(s) with respect to the mobile plates.
  • the recess is provided in the central part of the tab.
  • the recess is located between, that is to say is configured to separate, the first and second tongue parts.
  • the first tongue part has an increasing height from the distal edge of the tongue to the recess
  • the second tongue part has a decreasing height from the recess to the proximal edge of the tongue
  • the recess is provided in the second tongue part.
  • said recess has a general trapezoidal shape or a general V shape.
  • each extension comprises on a first field a tongue and a groove and on its opposite field a groove extending in line with the tongue of the first field and a tongue extending in line with the groove of the first field.
  • said movable plates and the extension(s) are obtained from HPL compact laminate, or any other equivalent composite material, and preferably have a thickness of between 8 and 20 mm.
  • the tongues and/or the grooves are obtained in the mass of the movable plates and/or of the extension(s) or are attached.
  • the table with central extension 1 comprises a frame 2, two movable plates 3, 4 resting on said frame 2 and capable of being moved closer to each other so as to constitute on their own a surface continuous, or to be separated symmetrically from each other, or one independently of the other, so as to allow the installation of one or more so-called central extensions 5 between said movable plates 3, 4.
  • the chassis 2 consists of a rectangular metal frame 6, preferably obtained from aluminum, consisting of two longerons 7 and two crosspieces 8 and at the corners of which are secured feet 9, obtained from aluminum or a rigid plastic material, said feet 9 being preferably inclined.
  • the two beams 7 respectively comprise a slide 10 making it possible to increase the dimensions of the frame 6, and conversely reduce the dimensions of the frame 6, for the installation and respectively the removal of a central extension 5 between the mobile plates 3, 4 which are integral with the frame 6 on each side of the slides 10.
  • the frame 2 may have any shape and any structure without departing from the scope of the invention.
  • the movable plates 3, 4 and the central extension 5 have a substantially rectangular shape;
  • the mobile plates 3, 4 and the central extension 5 may have any shape without departing from the scope of the invention.
  • the fields 11 of the movable plates 3, 4 and of the central extension 5 comprise a tongue 12 extending over a first half of said field 11 and a groove 13 extending over the second half of said field 11, said tongue 12 having a height increasing from its distal edge to its central part and decreasing from its central part to its proximal edge, and the depth of the groove 13 being greater than the height of the tongue 12.
  • the fields 11 may comprise several tabs 12 and several grooves 13 without departing from the scope of the invention.
  • the increasing part and the decreasing part of the tab 12 have the shape of a polynomial curve of the second degree.
  • Each extension has, with reference to the figure 4 and 6 , on a first field 11 a tongue 12 and a groove 13 and on its opposite field 11 a groove 13 extending in line with the tongue 12 of the first field 11 and a tongue 12 extending in line with the groove 13 of the first field.
  • the tongue 12 comprises in its central part a recess 14 which opens into a top surface of the tongue 12 and which is located between, that is to say configured to separate, the first and second parts of the tongue 12.1, 12.2.
  • the first tongue part 12.1 has an increasing height from the distal edge of the tongue 12 to the recess 14, and the second tongue part 12.2 has a decreasing height from the recess 14 to the proximal edge of tab 12.
  • the recess 14 could however be provided in the second tongue part 12.2.
  • said recess 14 has a generally trapezoidal shape; however, it is obvious that said recess 14 may have a general V-shape without departing from the scope of the invention.
  • edges of the tongue 12 are bevelled and/or rounded.
  • the mobile plates 3, 4 and the extension(s) 5 are obtained from compact HPL laminate, marketed for example by the company POLYREY, or from any other equivalent composite material, and have a thickness of between 8 and 20 mm.
  • the tongues 12 and the grooves 13 of the extension 5 and of the mobile plates 3, 4 make it possible to make a recessed assembly of the mobile plates 3, 4 between them or of the mobile plates 3, 4 with the central extension 5 which provides an upper surface of the plate is flat despite any deformations of the movable plates 3, 4 and/or of the extension 5, movable plates 3, 4 and/or of the extension 5 being perfectly aligned, ie coplanar with each other, even if the plates 3, 4 and/or the extension (5) are deformed.
  • tabs 12 and/or the grooves 13 are obtained in the mass of the mobile plates 3, 4 and/or of the extension(s) 5, or are attached without however departing from the framework of the invention.
