Definitions

  • the present disclosure relates to the field of mattress support devices, in particular support devices intended to extend between two long sides of a bed frame or seat (for example, for sofas or armchairs) to support the mattress.
  • Such devices are already known, which conventionally consist of laths fixed at their ends to the two long sides of the 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.
  • first elastic members On a first half of the crossbar, which is delimited between a first of its two ends and its middle, there are at least three first elastic members (it being specified that the middle is an integral part of this first half of the cross member, so one of these at least three first elastic members may, optionally, be placed at the exact location of the middle of the crossbar or withdrawn from this medium, on the side of the first end of the crossbar).
  • the longitudinal spacing between the two first elastic members (among these at least three first elastic members disposed between the first end and the middle of the crossbar) which are closest to the first end of the cross member is provided greater than the longitudinal spacing between the first two elastic members (among these same at least three first elastic members disposed between the first end and the middle of the cross member).
  • This longitudinal spacing difference results in a densification of the number of elastic members, when one moves away from the first end and approaches the middle of the crosspiece.
  • This density of elastic members in the central part of the device can be used to limit the slump of the platform under the weight of the user, and all the more effectively that this density is especially reinforced in this central portion, relative to the vicinity of the first end of the cross, less dense elastic members.
  • the longitudinal dimensions of the plate which is elastically supported by the elastic members, can be appropriately selected so as to ensure a certain degree of continuity of the support of the mattress in the width direction of the frame.
  • the longitudinal direction of elongation of the slender cross that is to say, the longitudinal direction of the slender cross.
  • This longitudinal direction also corresponds to the spacing direction of the two long sides of the frame, when the device is attached to the frame (this direction is therefore oriented in the direction of the width of the frame, when the two long sides effectively form the two most large sides of the frame).
  • This direction also corresponds to the main direction of elongation of the support device taken as a whole.
  • vertical is intended to denote the direction which is vertical when the device is fixed to the frame. This vertical direction also corresponds to the spacing direction of the upper and lower sections of the device.
  • horizontal plane is intended to denote a plane that is horizontal when the device is attached to the frame. This plane is therefore perpendicular to the vertical direction mentioned above. This plane also contains the longitudinal direction mentioned above.
  • transverse or “transversely” a direction contained in the horizontal plane and perpendicular to the main direction of elongation of the elongated cross. This direction is therefore a transverse direction relative to the longitudinal direction of this elongate cross. This transverse direction is also perpendicular to the spacing direction of the two long sections of the frame, when the device is attached to the frame. Moreover, this transverse direction corresponds to the direction of elongation of the two long pieces (this direction is therefore oriented in the direction of the length of the frame, when the two long sides actually form the two largest sides of the frame).
  • the longitudinal spacing between the two first elastic members closest to the first end may be at least 1.3 times greater than the longitudinal spacing between the first two elastic members closest to the middle of the the crossing.
  • This lower limit of 1.3 corresponds to a threshold below which it has been observed that the collapse of the central part of the device under the weight of the user is less effectively limited by the support of the elastic members, which are not significantly densified in the vicinity of the central portion of the device relative to the vicinity of the first end of the cross member.
  • the device may be desired to manufacture via a limited number of manufacturing steps, so as to simplify the manufacturing process and reduce the cost of manufacture.
  • the first elastic members may be made of the same material, for example the same plastic material.
  • the first elastic members may have identical shapes.
  • said plurality may comprise at least three second elastic members each disposed between the second of the two ends and the middle of the cross member, and the longitudinal spacing between the two second elastic members closest to the second end may be larger than the longitudinal spacing between the two second elastic members closest to the middle of the crossmember.
  • a second half of the crossbar which is delimited between the second of its two ends and its middle, it is possible to have at least three second elastic members (it being specified that the middle is an integral part of this second half of the cross member, so that one of these at least three second elastic members can, optionally, be placed at the exact location of the middle of the cross or withdrawing from this medium, on the side of the second end of the cross).
  • the longitudinal spacing between the two second elastic members (among these at least three second elastic members disposed between the second end and the middle of the crossbar) which are closest to the second end of the crossbar may be provided greater than the longitudinal spacing between the two second elastic members (among these same at least three second elastic members disposed between the second end and the middle of the cross member).
  • At least any one of the lower section, the intermediate section, and the upper section of the device may have a plane of symmetry. transverse to the cross, which may allow a simplification in the manufacturing process of the device.
  • plane of transverse symmetry is meant a plane of symmetry which is perpendicular to the longitudinal direction (it is therefore a vertical plane, perpendicular to the spacing direction of the two long sides of the frame , when the device is attached to the frame).
  • the device may be such that the plane of symmetry passes through the middle of the crossbar.
  • the device may further be such that the lower, middle and upper sections are each symmetrical with respect to the plane of symmetry.
  • the tray may be in one piece, which can provide an optimal continuity of the support of the mattress in the direction of the width of the frame.
  • the tray can be longitudinally disassociated into several distinct sections.
  • the plate can thus be cut into several distinct sections in the direction of the length (of the main direction of elongation) of the crossbar, the plate being formed by the attachment of these sections on the intermediate part of the device.
  • Cutting the plate in at least two distinct sections, to position one after the other in the direction of the length of the crossbar, can allow to mount these sections on any type of frame, regardless of the spacing distance of the two long sections of the frame. It thus becomes possible to standardize sections adapted to be mounted on different models of frames with spacing distances of two different long sections.
  • a first of said sections may longitudinally connect at least two elastic members among said at least three first resilient members.
  • Providing a section that is sufficiently long, in the longitudinal direction, to connect together at least two elastic members can ensure a better continuity of the support of the mattress along this longitudinal direction.
  • the first of said sections may longitudinally connect at least the first two elastic members closest to the first end.
  • the first of said sections may protrude longitudinally, relative to the first elastic members to which said first section is connected, more on the side of the first end of the cross member than on the middle side of the cross member.
  • This feature can allow the first section to sufficiently exceed the side of the first end so as to cover at least partially the first of the two long sections to which the first end of the cross is fixed. It can thus result in a better comfort and / or overall aesthetics for the device.
  • this characteristic can thus allow an overtaking of the first section, in the longitudinal direction and with respect to the first elastic members to which this first section is connected, as short as desired. It is thus possible to provide a longitudinal gap between the first section and the next section which is directly connected to it. adjacent as small as possible, which limits the discontinuity of support of the mattress to the passage from one section to another.
  • a second of said sections may be connected at least to that of the at least three first elastic members which is closest to the middle of the cross member.
  • This solution can be implemented when the first section is too short, in the longitudinal direction, to attach to all the resilient members located in the first half of the cross, so-called “first elastic members".
  • This configuration can occur when the spacing distance of the two long sections of the frame is particularly important compared to the dimensions of the first section, which it will for example be desired to "standardize” for all models of frames, regardless of the dimensions of these.
  • the presence of this second section can then compensate for the vacuum created by this first too short section.
  • the tray may have at least one contact area which is intended to come into contact with the mattress, and which has a relief to minimize contact with the mattress.
  • Such a relief may thus comprise at least a higher part, on which the mattress can be supported; and a lower part, intended to stay away from the mattress, when the latter bears on the upper part, so as to ensure a better flow of air around the mattress.
  • the relief may comprise at least one longitudinal succession of corrugations.
  • Such a relief may thus be such that, in the longitudinal direction, the upper parts and the lower parts alternately alternate to form a succession of corrugations.
  • This solution can optimize both the continuity of the mattress support and the flow of airflow along the longitudinal direction of the device.
  • the relief may comprise transversely several longitudinal successions of corrugations which are longitudinally offset relative to each other.
  • Such a relief may thus be such that, on a first portion, in the transverse direction, the plate has at least a first longitudinal succession of undulations; and, on a second portion, adjacent to the first portion in the transverse direction, a second longitudinal succession of corrugations whose extrema are offset, in the longitudinal direction, relative to the extrema of the first succession of corrugations.
  • This solution can optimize both the continuity of the mattress support and the flow of air flows in both longitudinal and transverse directions of the device.
  • the longitudinal successions of corrugations may have, each, the same spatial period and be longitudinally offset from each other by half of said spatial period.
  • Such a relief can thus be such that the minima of the undulations of the first succession coincide, in the longitudinal direction, with the maxima of the undulations of the second succession.
  • Such a configuration can further optimize the continuity of the support and the flow of air flows by densifying the maximum alternation of high and low parts in both longitudinal and transverse directions of the device.
  • the relief may comprise transversely at least three longitudinal successions of corrugations which are longitudinally offset from one another by half the spatial period.
  • Such a relief may thus be such that the maxima and / or minima of the corrugations of these three longitudinal successions are staggered in the so-called "horizontal" plane which is formed by the longitudinal and transverse directions of the device.
  • the tray may include recesses forming areas of material thinning allowing local decreases in tray stiffness.
  • This configuration can optimize the local deformations plateau to better adapt to the particular positioning of the user on the mattress, while maintaining a good overall continuity of the mattress support.
  • the recesses may be formed between the corrugations such that the corrugations are connected together. between them by the thinning areas of material, which can allow optimization of all the aforementioned parameters simultaneously.
  • the device may include at least one strap passing through the recesses to be alternately projecting below and above the tray.
  • Such a protruding strap thus mounted on the plate can thus be used to alternate between first parts of the strap projecting from the upper surface of the plate (and which are thus likely to come into contact with the mattress, when the latter comes to bear on the plate), and the second parts of the strap projecting from the lower surface of the plate (and which are therefore not visible from the upper surface of the plate).
  • This configuration can improve the overall aesthetics of the plate seen from its upper surface, which can alternate between raw material tray and textile material of the strap.
  • this configuration may further allow a better adhesion of the mattress, when the latter comes into support on the plate, at the place of the first parts of textile material.
  • this configuration may allow adjustment of the overall elasticity and / or local plateau, depending on the degree of tension of the strap relative to the plate.
  • the device may comprise at least one elastic body mounted to move on at least one of the elastic members to allow a modification of the stiffness of said elastic member.
  • a second aspect of this disclosure relates to an assembly comprising a bed frame or seat with two long sides; and a plurality of support devices according to the first aforementioned aspect each extending between the two long sides parallel to each other to support a mattress.

  • the assembly comprises a bed frame with two long sides 1L and 1R; and a plurality of support devices 10 each extending between the two long pieces 1L and 1R, parallel to each other to support a mattress (not shown in the drawings).
  • the support devices 10 each have a main elongation direction called "longitudinal direction" DL. In other words, these devices 10 are each broadly elongate in this longitudinal direction DL.
  • This longitudinal direction DL corresponds to the spacing direction of the two long sections 1L and 1R, when the devices 10 are fixed to the frame of the bed.
  • the devices 10 are arranged on the frame so as to be spaced from each other in a spacing direction called "transverse direction" DT.
