Definitions

  • the present invention relates to a folding table of the type comprising a tray, two legs pivotally mounted on one face of the tray and means for fixing the legs to the tray when the table is in the mounted position.
  • Such tables most often have very average stability and rigidity, that is to say that they are not able to support too heavy loads.
  • the object of the invention is to arrive at a folding table structure of an entirely new design and which makes it possible in particular to overcome the aforementioned drawbacks, while being easy to assemble and using only simple constituent elements and in limited number , in particular at the level of the joints and the means of fixing between legs and top.
  • each base comprises at least two parallel uprights connected one to the other by a first connecting element which supports part of the fixing means, the other part of which is supported by the plate, and by a second connecting element pivotally articulated to the plate.
  • the fixing means associated with each base comprise a single device constituted for example by a threaded rod supported by the first connecting element and by a tapped hole provided in the tray or in an integral intermediate element of the tray and into which the threaded rod is screwed to secure the connection between the base and the tray.
  • the two connecting elements form a rigid frame on which the plate comes to bear and such that the two uprights of at least one base, in the mounted position of the table, are found outside the tray.
  • the two uprights of a base which are then found outside of the table in the mounted position of the table, are hollow tubes in at least one of which can be engaged the end the support leg of auxiliary equipment such as a tablet.
  • Table 1 in accordance with the invention comprises a plate 2 and two legs 3 articulated on the underside of the plate 2.
  • each base 3 includes two uprights 4 such as two parallel tubular elements forming feet at one end and which, towards the other end, are joined by a first connecting element such as a bar rigid transverse 5.
  • Each base 3 is pivotally articulated to the plate 2 by means of a second connecting element such as a tie rod 6 connected to the uprights 4.
  • the tie rod 6 is in the form of a slightly metallic rod elastically deformable, U-shaped with a central part 6a and two lateral parts or wings 6b whose free ends are folded substantially at 90 ° outwards to form connecting pins 6c.
  • the tie rod 6 is not rigidly fixed to the uprights 4. After the lateral parts 6b have been brought together by elastic deformation and loosening thereof, the connecting pins 6c are positively engaged in two opposite holes 8 provided in the uprights 4 while allowing them to pivot relative to the axis formed by the two pins 6c axially aligned.
  • the central part 6a of the tie rod 6 comes to bear against the underside of the plate 2 parallel to the bar 5 and is held by two hinges 9 to pivotally connect each base 3 to the plate 2.
  • the uprights 4 can pivot around the connecting pins 6c and the tie rod 6 can pivot by means of the hinges 9, the uprights 4 can, thanks to these two articulations, take either a position at 90 ° relative to the plate 2 ( unfolded position shown in Figure 3), or a position substantially parallel to the plate 2 (folded position shown in Figure 4).
  • the hinges 9 are fixed on the underside of the plate 2 in a position such that the distance between the central part 6a of the tie rod 6 and the adjacent side 2a of the plate 2 parallel to said central part 6a is greater than the length of the wings 6b of the tie rod 6, so that the free ends of the uprights 4 opposite to those forming the feet come into contact with the plate 2 in the mounted position of the table 1 before being held in this position by fixing means 10 described below.
  • the fixing means between each base 3 and the plate 2 are constituted by a single device 10 which, in the example considered here, is a threaded rod 11a terminated at one end by a button b for controlling rotation, and a tapped hole 11b intended to receive the threaded rod 11a.
  • This rod 11a is mounted through the bar 5, substantially in the middle of the latter, and the tapped hole 11b is provided on the underside of the tray 2.
  • the length of the threaded rod 11a is greater than the distance separating the bar 5 from the tray 2, when each base 3 is in the unfolded position.
  • each hole 11 as shown in Figure 2 is made in the thickness of the associated plate 20.
  • Each plate 20 has, opposite the two uprights 4 of the associated base 3, two projecting cylindrical portions 21 with a diameter slightly less than that of the uprights 4 to fit into them and ensure better stability of the table 1 in the mounted position.
  • each base 3a, 3b is formed by two uprights 4 such that two parallel tubular elements forming feet at one end and which, at the other end, are joined by a first element of connection such as a rigid transverse bar 50.
  • Each base 3a, 3b is pivotally mounted on the plate 2 by means of a second connecting element such as a U-shaped bar 60 whose two free ends of the two lateral parts or wings 60b are connected to the uprights 4, so that the bars 50.60 are in contact with the plate 2 when the table 1 is in the assembled position.
  • the central part 60a of the bar 60 bearing against the underside of the plate 2 is held by two hinges 9 allowing the base 3a, 3b associated to pivot relative to the plate 2.
  • the hinges 9 are fixed on the underside of the plate 2 in a position such that the distance from the central part 60a of the bar 60 and the adjacent side 2a of tray 2 parallel to said central part 60a is greater than the length of the lateral parts 60b of the bar 60, so that the free ends of the uprights 4 opposite to those forming the feet come into contact with the plate 2 in the mounted position of the table 1 .
  • the hinges 9 are fixed on the underside of the plate 2 in a position such that the length of the lateral parts 60b of the bar 60 is greater than the distance separating the hinges 9 on the adjacent side 2a of the plate 2 parallel to the central part 60a of the bar 60, and that the distance separating this central part 60a and the bar 50 is less than the aforementioned distance.
  • the uprights 4 are found outside the plate 2, while the bars 50 and 60 are in contact with the plate 2 to ensure the stability and rigidity of the table 1.
  • the fixing means 10 are constituted as in the first embodiment by a single device 10 such as a threaded rod 10a, with a rotary control button 10b, which is supported by the bar 50 and which cooperates with a tapped hole 11b provided in the underside of the plate 2 or in an intermediate plate 20 ′ fixed to the plate 2.
  • the external position of the base 3b relative to the plate 2 makes it possible to associate with the table an auxiliary equipment such as a shelf T which is for example supported by a tubular upright 4 ′ forming a foot which can partially fit into one of the uprights 4 of the base 3b.
  • This tablet T is for example a telephone tablet, when the table serves as an office.
  • the fixing device 10 used in the two embodiments described above can be replaced by any equivalent device such as that illustrated in Figure 8.
  • each fixing device 10 is of the automatic snap-on type with an elastically retractable pin 12b which cooperates with an orifice 12a.
  • the pin 12b projects in part from a housing 70 fixed to the underside of the plate 2.
  • This housing 70 contains a spring 71 which allows the pin 12b to retract inside the housing 70.
  • the orifice 12a is provided in the first connecting element 5, 50 of each base 3, 3a and 3b.
  • the connecting element 5, 50 of each base 3 at the end of the latter's pivoting movement comes into contact with the associated pin 12b and forces it to retract temporarily to inside the housing 70.
  • the orifice 12a of the connecting element 5, 50 faces the pin 12b, the latter protrudes again from the housing 70 to engage in the orifice 12a and ensure thus the fixing between the base 3 and the plate 2.
  • each fixing element 10 associated with each base 3.3a, 3b can also be constituted by a simple screw.
