Definitions

  • the present invention relates to the slatted or multi-element type slatted frame or seat suspension elements provided with firmness adjustment means.
  • suspension elements commonly use suspension elements.
  • special arrangements are provided to vary the elasticity or firmness of these suspension elements.
  • the suspension elements are in the form of a one-piece structure provided with deformable spring blades.
  • the particular arrangements made with these leaf springs make it possible, with the aid of inserts and interchangeable parts, to modify their elasticity by the addition of complementary spring elements.
  • suspension members consisting of an elastic connection interposed between an upper head receiving a slat and a lower base, said elastic connection being formed of articulated arms extending in the direction of the longitudinal axis of the upper head.
  • a slider system is arranged to move along the length of one or more of the articulated arms, so as to modify the deformation capabilities of the elastic link.
  • the corresponding firmness adjustment means, of the slider type are relatively complex, they are of a large size and require substantial displacement to obtain a significant difference in terms of firmness.
  • the document FR-2,839,870 of the Applicant presents a suspension element for a bed base (or seat) of the slatted or multi-element type which consists of a lower base, an upper head and an intermediate system of elastic connection.
  • the lower base is provided with fixing means on the frame of the bed base (or seat), or on a member integral with this frame.
  • the upper head is arranged to accommodate and fix one or more slats, or a tray; it comprises a longitudinal axis adapted to extend in the width direction of said bed or seat.
  • the elastic intermediate connection is arranged between said base and said head to allow a vertical displacement of the latter to the base, according to at least one component perpendicular to this base.
  • This elastic connection comprises, on the one hand, two rigid arms V e whose one end is secured to either the head or the base, by means of hinge means, and on the other hand, a spring portion extending between the other end of said arms and said head or said base, as the case may be.
  • This suspension element further comprises means for adjusting and controlling the amplitude of the angular movement of said arm or said arm relative to said head or base during said vertical displacement of said head, so as to allow to modify at will its firmness characteristics. .
  • the two V-arms (and the associated spring portions) are oriented perpendicularly to the longitudinal axis of the head (and thus in the direction of the side rails of the bed frame or seat structure) , which may allow possibilities of excessive oscillations of the slats or the supported plate because of the presence of the firmness adjustment means (and the head / arm articulation means).
  • the present invention proposes to remedy these various disadvantages.
  • the base is provided with fixing means on one of the longitudinal longitudinal members of the bed frame structure (or seat), and the head is provided with at least one housing for the reception of a batten, the arm or arms of the elastic connection extending in the direction of the axis of said batten receiving housing (s), corresponding to the direction of the longitudinal axis of said head.
  • the suspension element may comprise a single arm centered on the median longitudinal plane of the head, which arm is extended by a spring element shaped flat blade.
  • the arm or arms of the suspension element extend from the head down towards the interior of the bed, that is to say between its two longitudinal longitudinal members.
  • this suspension element namely the base, the head and the elastic connection between the two, is advantageously in a one-piece form made of thermoplastic material of elastomer type.
  • a firmness control system 9 is interposed between the head 5 and the elastic connection 8.
  • the elastic connection 8 consists of a spring element 10 interposed between the base 4 and an arm 11 integral with the head 5.
  • the arm 11 extends in the direction of the axis 7 of the head 5 (and also in the direction of the axis of the slats housing 6 ') and it constitutes a deformation lever of the spring element 10.
  • This arm 11 is articulated at 12 at its zone of attachment to the head 5.
  • the spring element 10 extends the arm 11 and it also extends in the direction of the axis 7 of the head 5; it is in the form of a flexible blade in the general shape of C, for example in ellipse portion.
  • the arm 11 is advantageously in the form of a flat of a few centimeters in width and length, and a few millimeters thick.
  • the spring element 10 is advantageously in the form of a flat blade of a few centimeters in width and length, and 1 to 2 mm thick.
  • the head 5, the base 4 and the elastic connection 8 are made in one piece by molding thermoplastic material elastomeric type, the hinge areas 10, 12 being obtained by material thinning.
  • the hinge 12 is in the form of an elongated thinning which extends on a line perpendicular to the longitudinal axis 7 of the head 5.
  • the movement of the head 5 (linked to a support on the slats 6 in particular) is accompanied by a movement of the arm 11 and in particular a pivoting of the arm 11 around its hinge 12, and at the same time, observe a deformation of the spring element 10.
  • This firmness control system 9 comprises means consisting of at least one cam-shaped piece 13 , reported and interposed between the arm 11 and the head 5, and in particular between one or more lugs 14 integral with the arm 11 and a bearing surface 15 acting as a stop, situated under the head 5.
  • the displacement of the cam 13 makes it possible to modify at will the movement capacity of the arm 11 and in particular the amplitude of its angular movement around its hinge axis 12.
  • This control of the movement of the arm 11 influences the deformation capacity of the elastic means 10 and makes it possible to control the firmness of the ball joint.
  • the adjustment of the firmness of the suspension element 1 is achieved by a simple displacement of the cam 13, this at will, directly during the making of the bed base, or by the user himself.
  • cam 13 can be implemented, operating by rotation or by translation, in particular as detailed in the document FR-2,839,870 .
  • the bearing surfaces of the cam 13, the number and the position of the chins 14 will be adapted accordingly.
  • the positioning of the plane arm 11 (and of the associated elastic element 10) in the direction of the axis 7 of the head 5 makes it possible in particular to limit the possibilities of lateral oscillations of the slat or slats 6, in particular because of the orientation of the hinge 12 (this orientation being perpendicular to the axis 7 of the head 5). This positioning also allows a significant suspension stroke.
  • the base 4 and the head 5 are connected by an elastic connection 8 (arm 11 extended by an elastic element 10), which is located on the central axis 7 'of the suspension element.
  • the head 5 and the base 4 may be connected by several parallel arms oriented in the same direction (each associated with a spring element).
  • the arm 11 extends from the head 5 towards the inside of the bed base (between the two longitudinal longitudinal members 2), the C shape of the elastic element 10 being open towards the outside of the frame.
  • the orientation of the arm (or arms) and the associated spring element can be reversed, the arm then extending downwards and towards the outside of the bed base, and the element C spring being open towards the interior of the bed.
  • this suspension principle can be implemented to form a slider that is positioned on slats interposed between the longitudinal longitudinal members of the bed.
