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 frame of an extendable table having great rigidity both in the closed position and in the extended position in which one or more so-called central extensions can be positioned between two movable plates integral with said frame.
  • 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 the tables with central extension, comprising above of a chassis two movable plates capable of being moved closer to each other so as to constitute a continuous surface on their own 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 equal height at the height of the one or two main shelves plus the height of the extension shelf of the table, each of these two sides comprising on its inner face at least one straight longitudinal guide path or notch as well as at least two guide paths or vertical 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 as the shelf extends prominent elements such as pivots, teeth or ridges, capable of allowing 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 only to allow such movement, of the one or two main shelves, that the extension shelf is not only cleared but
  • 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.
  • Extendible tables are also known, the dimensions of the frame of which are adaptable to receive one or more extensions of the top. This is particularly the case of the American patent US3912210 .
  • the document US3912210 describes a frame of a table or the like comprising two rails and two crosspieces arranged horizontally and extending perpendicularly in pairs to form a substantially rectangular frame, as well as four vertical legs extending to the four corners of said frame.
  • the spars and the crosspieces consist of profiled tubes of rectangular or square section in which extend tenons inserted and fixed in the opposite tubes of two parts of the adjoining structure.
  • This type of table has the disadvantage of not allowing a large extension of the dimensions of the frame. Furthermore, in the extended position, the frame of the table does not have sufficient rigidity.
  • 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 frame of which comprises extension means allowing the installation of one or more extensions while guaranteeing great rigidity of the frame and, ultimately, of the table.
  • 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 mobile plates, said chassis consisting of two spars of variable length, two crosspieces, said crosspieces and the spars being assembled perpendicularly in pairs to form a horizontal frame, and four vertical legs extending to the four corners of the frame under the latter; said table is remarkable in that each spar comprises two parts, a so-called fixed spar and a so-called mobile spar, the fixed spar and the mobile spar being made up of a profile of rectangular cross section in which extends a slide of cross section rectangular and comprising a longitudinal central groove, the free ends of the slide each being provided with a slide end piece, and the distal ends of the fixed and mobile beams being respectively provided with
  • the longitudinal central groove of the slide has a rectangular or square cross-section and receives a square nut capable of cooperating with a butterfly screw, the threaded rod of which extends through a hole made on the external wall of the movable spar, the longitudinal slot opening into the longitudinal central groove having a width less than that of the longitudinal central groove and a width greater than the diameter of the threaded rod of the butterfly screw.
  • the slide comprises on either side of the longitudinal central groove a channel.
  • Each slide end piece consists of a parallelepipedic piece open at one of its ends to receive the free end of the slide and provided with square recesses capable of receiving square nuts to allow the slide end piece to be fixed to the free end of said slide by means of screws cooperating with said square nuts.
  • the slide head and the complementary slide head consist of a parallelepipedic main body open at both ends, to allow passage of the slide, and at one of their ends of a plate extending perpendicular to the longitudinal axis of the main body and provided at the upper end of the plate with a lug and an aperture, the lug of the slide head being capable of being inserted into the aperture of the complementary slide head and vice versa.
  • the lug of the slider head and of the complementary slider head has a substantially triangular shape, the opening of the slider head and of the complementary slider head having the shape of a vertical rectilinear slot.
  • Said light of the slide head and of the complementary slide head extends parallel to and along the triangular lug of the slide head and of the complementary slide head.
  • the extending table according to the invention comprises foot brackets connecting the crosspieces to the side members and capable of receiving the feet which are fixed to said foot brackets.
  • Each foot bracket comprises a ring capable of receiving the upper end of a foot and two tenons extending on either side of the ring forming a right angle, said tenons being capable of being inserted into the sections forming the longitudinal members and the crosspieces.
  • the extending table according to the invention comprises reinforcing brackets positioned on the rear face of the foot brackets and traction brackets positioned on the rear face of the reinforcing brackets.
  • the mobile plates and the extension(s) are obtained in HPL compact laminate.
  • the extendable table according to the invention comprises a compartment integral with the lower wall of one of the mobile plates and capable of receiving at least one extension.
  • the central extendable table 1 comprises a frame 2, two mobile 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 continues, or to be separated symmetrically from one another, or one independently of the other so as to allow the establishment 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 consisting of two longerons 7 and two crosspieces 8 and at the corners of which are secured feet 9, also metal, said feet 9 preferably being 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 wings 10, as will be detailed below.
  • 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.
  • each spar 7 comprises two parts, a so-called fixed spar 7a and a so-called mobile spar 7b of length greater than the length of the fixed spar 7a.
  • the mobile beam 7b of a first beam 7 of the frame 2 extends to the right of the fixed beam 7a of the second beam 7 of said frame 2.
  • the fixed beam 7a and the moving beam 7b consist of a profiled tube with a rectangular cross section in which the slide extends 10 of also rectangular cross-section and comprising a longitudinal central groove 11, the free ends of said slide 10 each being provided with a slide end piece 12, and the distal ends of the fixed 7a and mobile 7b beams being respectively provided with a head slide 13 and a complementary slide head 14 capable of cooperating by interlocking with the slide head 13 when the frame 2 of the table is in the so-called closed position, ie when the movable plates 3 and 4 are contiguous.
  • Said longitudinal central groove 11 of the slide 10 has a rectangular or square cross section and receives a square nut 15 capable of cooperating with a butterfly screw 16 whose threaded rod 17 extends through a hole 18 made on the outer wall of the spar moveable 7b ( figures 6 and 7 ).
  • the slide 10 further comprises a longitudinal slot 19 opening into the longitudinal central groove 11 and having a width less than that of the longitudinal central groove 11 and a width greater than the diameter of the threaded rod 17 of the butterfly screw 16 ( figure 10 ).
  • This butterfly screw 16 makes it possible to block the slide 10 in a determined position, ie in a closed position or in an extended position.
  • the slide 10 comprises on either side of the longitudinal central groove 11 a channel 20 in order to limit the weight of the slide 10 while ensuring good rigidity.
  • each slide end piece 12 consists of a parallelepipedic piece open at one of its ends to receive the free end of the slide 10 and provided with square recesses 21 adapted to receive square nuts 22 to allow the fixing of the end piece slider 12 at the free end of said slider 10 by means of screws 23 cooperating with said square nuts 22.
