Definitions

  • the present invention relates to the fields of furniture and bedding, and more particularly that of suspension devices intended to be interposed between a mattress and a support structure.
  • conventionally used devices consisting of slats attached at their ends to the two longitudinal members of a bed frame or seat. Such slats directly support the mattress, over the entire width of the latter, which ensures a continuity of support for the user in the direction of the width of the frame.
  • Supporting devices capable of attenuating sagging of conventional lathed devices while maintaining a certain degree of continuity in supporting the mattress in the width direction of the frame have been proposed, particularly in French patent application publications. FR 3,005,400 and FR 2 914 164 .
  • these devices have complex shapes, formed by assemblies of several parts, which makes them relatively complex and expensive in their production.
  • a monoblock device has been proposed in the publication FR 2,859,891 , but its manufacture also requires several stages.
  • Other monobloc devices have been disclosed in the German patent DE 10 2012 107887 B3 , in the European patent application publication EP 2 489 288 A1 and in the German utility certificate DE 20 2007 000158 U1 .
  • the present disclosure aims to remedy these drawbacks, and more specifically to provide a monobloc suspension device, intended to be interposed between a mattress and a support structure, which can be manufactured in a simpler and more economical manner while providing greater comfort. .
  • this object is achieved by virtue of the fact that this one-piece device, which comprises a plate defining a support plane of the mattress, a point of attachment to the support structure, and a more elastic elastic section than the plate in the direction perpendicular to the bearing plane and interposed between the plate and the fixing point in the direction perpendicular to the bearing plane for absorbing compression forces, is shaped such that any axis perpendicular to said bearing plane passing through the monobloc suspension device intersects the monoblock suspension device on a single axis segment.
  • the elastic section may comprise at least one elbow element comprising a first arm and a second arm, a first elastic hinge on a first end of the first arm, and a second elastic hinge, more flexible than the first elastic hinge, connecting a second end of the first arm to the second arm, and forming a bend so that the first arm has a larger angle by report to said support plan as the angle of the second arm with respect to said support plane.
  • An additional advantage of this configuration lies in the handling and the logistic management of a plurality of such monoblock devices, because this configuration makes them stackable, thus substantially reducing their storage volume.
  • the plate may have an opening facing the attachment point and the elastic section in the direction perpendicular to the support plane.
  • the elastic section may in particular at least two bent elements arranged symmetrically to one another, following a plane of symmetry perpendicular to said support plane.
  • the upper arm and the lower arm of each elbow element can inclined in the same direction relative to the support plane.
  • a configuration in which the upper arm and the lower arm of each bent element are inclined in opposite directions relative to the support plane is also possible and facilitates the bending of the bent element under compression.
  • the one-piece device may be made of thermoplastic material.
  • the one-piece device can be made of elastomeric material. Simultaneously thermoplastic and elastomeric materials may be used, such as, for example, an elastomeric thermoplastic copolyester.
  • a fixing hole may be formed at the point of attachment.
  • the attachment point may be located on a base distinct from the elastic section, but also on the elastic section itself.
  • the tray may have vents.
  • the tray may have a rectangular outer contour.
  • rectangular is meant in this context any contour with four edges in right angles, including square contours. Moreover, these right angles can be rounded or bevelled.
  • the present disclosure also relates to a monoblock module comprising at least one monobloc device such as those mentioned above.
  • the monoblock module may include several such monobloc devices, aligned in a direction parallel to said support plane and connected by their respective trays, thus allowing their attachment to the same cross.
  • the monobloc suspension devices of the same monoblock module having several monobloc suspension devices can be identical to each other.
  • the present disclosure also relates to an assembly comprising a support structure and at least one monoblock module such as those mentioned above fixed on the support structure.
  • this set may comprise a plurality of these monoblock modules fixed on one and the same face of the same crossmember of the support structure, although it is also conceivable to fix a single monoblock module extending over the entire length of the structure. such a cross.
  • the assembly comprises a plurality of monoblock modules
  • this plurality may comprise monoblock modules of different sizes, and in particular incorporating different numbers of identical monobloc suspension devices to one another, to offer modularity.
  • the support structure may for example be that of a conventional bed base, comprising two longitudinally oriented longitudinal members and a plurality of cross members connecting the two longitudinal members in the transverse direction.
  • FIGS. 1 and 2A to 2C illustrate a first embodiment of a monobloc module 1 comprising a single monoblock suspension device 2 intended to be interposed between a mattress and a support structure in a bed or the seat of a piece of furniture such as a sofa or a sofa. sofa.
  • This monoblock suspension device 2 comprises a plate 3, defining a support plane A of the mattress, a base 4 with a fixing orifice 5 on a fixing point, and an elastic section 6, more elastic than the plate 3 in the direction perpendicular to the support plane A and interposed between the plate 3 and the base 4 in the direction perpendicular to the support plane A to absorb compression forces.
  • the monoblock module 1 may be made in one piece of thermoplastic elastomer material, for example elastomeric thermoplastic copolyester, by a method such as injection molding.
  • the plate 3 has a rectangular contour with rounded corners and a plurality of ventilation orifices 7, as well as a central opening 8 facing the elastic section 6 and the base 4 in a direction perpendicular to the support plane A.
  • the elastic section 6 is formed by two bent elements 9 arranged symmetrically to each other, along the plane of symmetry IIC-IIC perpendicular to said bearing plane A.
  • Each of these bent elements 9 comprises a first arm 9a and a second arm 9b.
  • the first arm 9a a first end of which is connected to the plate 3 by a first elastic hinge 9c, extends towards the base 4 with an angle ⁇ [ALPHA] right or almost right with respect to the support plane A.
  • this angle ⁇ [ALPHA] can be, for example, between 80 ° and 90 °.
  • a second end of the first arm 9a is connected to the second arm 9b by a second elastic hinge 9d forming an elbow, so that the second arm 9b extends towards the base 4 with an angle ⁇ [BETA] substantially less than the angle ⁇ [ALPHA] relative to the support plane A.
  • this angle ⁇ [BETA] can be between 0 ° and 60 °.
  • a third elastic hinge 9e in turn connects the second arm 9b to the base 4.
  • any axis Z 1 or Z 2 perpendicular to said support plane A passing through the monobloc suspension device 2 intersects the monobloc suspension device 2 on a single intersection segment S 1 , S 2 corresponding.
  • the relationship between points of a projection of the monobloc suspension device 2 on said support plane A, as illustrated in FIG. Figure 2A , and intersecting segments of axes perpendicular to the support plane A with the monobloc suspension device is therefore bijective: at each point of the projection corresponds a single intersection segment.
  • the monoblock device is free of undercuts.
  • the first elastic hinge 9c is more rigid than the second and third elastic hinges 9d and 9e.
  • the angular deflection when a force F is exerted between the plate 3 and the base 4 along an axis perpendicular to said support plane A is thus greater at the second and third elastic hinges 9d, 9e than at the first elastic hinge 9c, folding thus the elbow formed between the first arm 9a and the second arm 9b under this load, as illustrated in FIG. figure 3 .
  • the elastic hinges 9c to 9e will relax, bringing the elastic section 6 to its initial position.
  • the viscoelastic nature of the elastomer forming the monoblock suspension device 2 will ensure this elastic return and appropriate damping of the bending and relaxing movements of the bent elements 9 of the elastic section 6.
  • the monoblock module 1 has only one monobloc suspension device 2, it is also possible to include several such monoblock suspension devices in a single monobloc module.
  • a single monoblock module 1 'comprises two identical monobloc suspension devices 2, 2'.
  • a single monoblock module 1 "even comprises three monoblock suspension devices 2, 2, 2", each also comprising the same elements as the first embodiment, which therefore receive the same reference numbers in the drawings.
  • the monobloc suspension devices 2, 2 ', 2 are connected by their trays 3, and aligned in a direction parallel to their common support plane A, so as to allow their attachment to a same crosses.
  • the figure 8 illustrates an exemplary embodiment of an assembly comprising a support structure 10, and a plurality of monoblock modules 1, 1 ', 1 "fixed on this support structure 10 by screws (not shown) passing through the fixing orifices 5 bases 4 of each monobloc suspension device 2.2 ', 2 ".
  • the support structure 10 comprises a frame with two longitudinally oriented longitudinal members 11, and a plurality of crosspieces 12 transversely connecting these longitudinal members 11.
  • the monoblock modules 1, 1', 1" are fixed on the outer face of each cross member 12, aligned along the cross members 12, with a common support plane A to support the mattress.
  • modules 1.1 ', 1 "of different sizes incorporating one or more monobloc suspension devices it is possible to combine modules 1.1 ', 1 "of different sizes incorporating one or more monobloc suspension devices to cover the support structure 10 over its entire width.
  • the rectangular shape of the trays 3 provides a good filling of the surface of the support structure 10 on the support plane A.
  • each bent element 9 is inclined in the same direction relative to the support plane A
  • an alternative configuration is conceivable in which they are inclined in opposite directions. such that the fixing element is raised relative to the elastic hinge 9d forming a bend.
  • This configuration is that of the fourth embodiment, illustrated on the Figures 9, 10A and 10B , on which elements equivalent to those of the previous embodiments are given the same reference numerals.
  • this fourth embodiment in which the monoblock module 1 "comprises several one-piece suspension devices 2,2 ', 2" is also distinguished from the second and third embodiments in that the bending planes of the elbow elements 9 are perpendicular to the direction in which the monoblock suspension devices 2,2 ', 2 "of the monoblock module 1" are aligned.
  • each monobloc suspension device is formed on a base distinct from the elastic section, it may also be formed in the elastic section itself.
  • the second arms 9b of the two symmetrical elbow elements 9 are not connected to a separate base by third elastic hinges, but meet directly, and the fixing orifice 5 is formed at their junction.
  • the first arm 9a and the second arm 9b of each bent element 9 are inclined in opposite directions relative to the support plane A, so that the fixing orifice 5 is raised relative to at the second elastic hinges 9d.
  • This embodiment also has the advantage of allowing prestressing of the elastic section 6 when it is fixed on a flat surface which will straighten the lower arms 9b and begin to fold the second elastic hinges 9d.
