Definitions

  • the invention relates to the field of suspension slats of a slatted bed base.
  • It relates more specifically to a suspension device of two slats on a long pan, comprising a one-piece nozzle which has, in its lower section, means for fixing said tip on the inner face of said long pan, in its upper section, two housing to receive the ends of said two slats, and, in its middle section, elastic means connecting the lower section to the upper section, as known from the document EP 0 512 569 .
  • the elastic means are constituted by thin rectilinear or curvilinear walls which form between them orifices passing through an axis parallel to the axis of the slats.
  • the object of the invention is to provide a compact suspension device whose stiffness can easily be modified.
  • the elastic means consist of two arcuate lateral tabs respectively disposed under a batten and having a C-shaped section in vertical planes parallel to said two slats, said two tabs each having an upper branch connected to the upper section and a lower branch connected to the lower section, and in that said device further comprises a closed bag having an airtight deformable wall, said pocket substantially filling the free space of said mouthpiece delimited by vertical generatrices and horizontal generatrices perpendicular to the axis of the slats, which rest on the contour of said tip.
  • the lower ends of the lower branches of the two tabs are interconnected by a web and are each disposed above a fixing means.
  • the fixing means are preferably constituted by two hollow sleeves.
  • the underside of the pocket has a shoulder for receiving the inner upper edge of the long pan.
  • the bag is made in two pieces by molding an elastomer, said two parts then being sealed together along a joint plane.
  • the pocket contains a gas under pressure.
  • the proposed suspension device further comprises a slider slidably mounted on said two slats, said slider having a lower end capable of being positioned between the two upper branches of the tabs in order to compress the pocket .
  • the pocket has between the upper branches of the legs an easily deformable wall area.
  • the device further comprises means for immobilizing the cursor relative to the tip.
  • the immobilizing means comprise for example ribs and grooves capable of cooperating with each other and formed on the legs and the slider.
  • the slider preferably comprises two pairs of opposite parallel wings, the wings of a pair providing between them a space to receive a slat edge.
  • the stiffness of a suspension can thus be adjusted by choosing a suitable pocket from a set of wall pockets of different thicknesses for example or containing a gas under different pressures. It can then be adjusted more accurately by moving the cursor.
  • This device 1 consists of two parts, namely, a one piece piece 4 and a closed pocket 5. It may optionally comprise a slider 6.
  • the tip 4 is made in one piece by molding a suitable elastomer.
  • the middle section 15 has two arcuate tabs 16a and 16b arranged laterally on either side of the vertical plane of symmetry of the two slats 2a, 2b, each under a batten.
  • These two tabs 16a and 16b have a C-shaped section in parallel vertical planes to the slats 2a and 2b and each have an upper branch, 17a for the tab 16a and 17b for the tab 16b, connected to the upper section 13, and a lower branch, 18a for the tab 16a and 18b for the tab 16b.
  • the lower ends of the lower branches 18a and 18b are connected by a web 19 and are respectively connected to the sleeves 11a and 11b.
  • the sleeves 11a and 11b are arranged under the lower ends of the lower branches 18a and 18b.
  • the upper branches 17a and 17b of the tabs 16a and 16b extend under the lower faces of the slats 2a and 2b and are connected to the lower walls of the housings 14a and 14b.
  • the upper walls 20a and 20b of the housings 14a and 14b are also connected by a web 21 which connects to a vertical wall 21a connecting the housings 14a and 14b on the side of the slats 2a and 2b.
  • the web 21, the vertical wall 21a and the housings 14a and 14b thus delimit a cavity 22a.
  • a rib 21b perpendicular to the slats 2a and 2b is formed under the underside of the web 21.
  • the tip 4 thus has between the two arched tabs 16a and 16b an indentation 22.
  • the arcuate tabs 16a and 16b constitute first means of elastic suspension of the two slats 2a and 2b on the long section 3.
  • the closed pocket 5 constitutes second means of elastic suspension of the two slats 2a and 2b on the long pan 3.
  • This pocket 5 comprises a deformable airtight wall, and occupies substantially all of the free space of the nozzle 4 delimited by vertical generatrices and horizontal generatrices perpendicular to the axis of the slats 2a and 2b, which rely on the contour of the tip 4, seen from above and seen laterally.
  • the pocket 5 is thus in abutment against the concave faces of the tabs 16a and 16b and occupies the cavity 22a. It can also occupy the notch 22.
  • the lower face 30 of the pocket 5 has a shoulder 31 in which the inner upper edge 3a of the long pan 3 is housed.
  • the upper face 51 of the dome 52 accommodating in the cavity 22a has a groove 53 in which the rib 21b of the web 21 is housed. Due to the presence of this inner edge 3a in the shoulder 31, of the rib 21b in the groove 53 and of the dome 52 in the cavity 22a, the pocket 5 is immobilized with respect to the tip 4 and with respect to the longpan 3 after mounting the device 1 on the longpan 3 in the longitudinal and transverse direction.
  • the pocket 5 is made in two pieces 32, 33 by molding a suitable elastomer. These two parts 32, 33 are then assembled in a joint plane, either by gluing or not welding, so that the pocket 5 is closed and airtight.
  • the joint plane is chosen in such a way that the parts can be made by simple molds.
  • the references 34, 35 designate respective zones of the parts 32 and 33 which can be in relief on their external faces and which are intended to occupy the volume of the notch 22.
  • the thickness of the wall of the pocket 5 is calculated so as to ensure in operation the desired suspension stiffness.
  • the assembly of the two parts 32 and 33 can be realized in a chamber containing a gas under an adjustable pressure, in order to allow the adjustment of the stiffness of the pockets 5.
  • the pocket 5 ensures with the tabs 16a and 16b of the tip 4, the elastic suspension of the slats 2a and 2b on the long side 3.
  • the stiffness of the suspension can be adjusted by means of the slider 6.
  • the slider 6 comprises a body 40, solid or lightened, which is positioned in the space between the two slats 2a and 2b, and which has in its upper region two pairs 41a, 41b of parallel wings 42a, 42b and opposite.
  • the wings 42a and 42b of a pair form between them a space 43 intended to house the edge of a batten 2a or 2b.
  • the height of the body 40 is chosen so that the lower end 44 of the body 40 of the slider 6 can be positioned between the upper branches 17a and 17b of the tabs 16a and 16b, in the notch 22, where it presses the pocket 5, which decreases the internal volume of the pocket 5 and thereby increases the stiffness of the suspension.
  • the body 40 of the slider 6 has under the pairs of wings at least one vertical rib 45 which can cooperate with ribs 46a, 46b formed on the edges of the upper branches 17a, 17b of the side of the notch 22, in order to immobilize the slider 6, positively in a pre-established position according to the selected rib 46a or 46b.
  • Figure 6 shows the configuration of the pocket 5 when the slider 6 is spaced from the nozzle 4.
  • Figure 7 shows the deformation experienced by the pocket 5 when the slider 6 is in maximum support on it.
  • Figure 9 shows a device 1 consisting of only two parts, namely, a one-piece nozzle 4 and a closed bag 5 containing a gas under pressure.
  • the one piece piece 4 is similar to that described above, except that the web 21 which connects the upper walls 20a and 20b of the housings 14a and 14b is wider. This web 21 is also connected to the vertical wall 21a which connects the housing 14a and 14b on the side of the slats 2a and 2b.
  • the cavity 22a is thus larger and so is the dome 52 of the pocket 5.
  • the pocket 52 contains a gas under pressure. The stiffness of the suspension is thus a function of the thickness of the wall of the pocket 5 and the pressure of the gas contained therein.
