Definitions

  • Spring bodies for cushion pads are known to consist of elastic plastic material and can be compressed in a spring travel directed in the direction of the effective contact force of the loaded cushion pad.
  • the deformation of the spring body can be influenced by its material properties and the design of the spring elements.
  • At the upper or lower ends of the spring body there are generally plate-shaped support rings for fastening the spring body to a foot element or to a cover plate. This overall arrangement then forms a support element for supporting a cushion pad.
  • the sections of the spring plate element which are separated from one another by the slots in the central region of the spring plate element are brought together in the foot or head region outside the slots to form a stable support.
  • high arching stresses can occur in particular in the foot region of the spring element, which can lead to bulging of the spring element.
  • This effect is even more pronounced if the shell shape has small geometric imperfections.
  • This danger also exists in the case of an asymmetrical introduction of force via the support ring directed towards the cushion pad and an overstressing of a section of the arcuate spring element caused thereby.
  • this can also lead to a buckling or buckling-like bulging out or denting of the overstressed spring element area and thus to a total failure of the spring element.
  • EP 0996349 B1 It is also known from EP 0996349 B1 to design the spring body in the form of narrow web-like spring arms. These start from a base plate, which is used to hold a screw for fastening to the slatted frame, and open into an upper star-shaped, horizontally deformable support plate.
  • the object of the invention is to create a spring element which is designed in such a way that its deformation behavior can be better controlled.
  • the transition of the spring tongue into the support ring is designed such that a straight edge is formed and this forms part of an outline of the support ring and the lateral edges of the spring tongue are free up to the straight edge.
  • the shape according to the invention also allows asymmetrical or uneven loads on the spring element.
  • the resulting stresses can be due to the horizontal degree of freedom due to the lateral clearance of the edges of the spring tongues are recorded, whereby the inevitably inevitable occurrence of deformations in the form of warping or twisting due to the eccentricity can be kept low.
  • the possibility is also created of having the deformations occur at predefined locations and in predetermined directions.
  • support ring used in the context of this invention is understood to mean a ring that is closed or open in the circumferential direction, ring-like frame, plate strips or similar designs of any geometric shape.
  • this also basically includes shapes in the circumferential direction any linear, non-linear, parallel and non-parallel inner and outer contour lines.
  • one aspect of the invention also provides that the number of straight edges corresponds to the number of spring tongues. If only rectilinear edges are used to form the contour line (with the exception of small fillet areas between the ends of the edges), at least triangular or polygonal contour lines of the support ring are produced, with a spring tongue adjoining each rectilinear edge.
  • a further preferred embodiment consists in that the spring tongue adjoins this on an inner contour line of the support ring.
  • the force transmission taking place in the area of the edges can be influenced by the support ring in the respective spring tongue and the direction of deformation of the spring element can also be controlled. Due to the connection to the inner contour line, the support line of the support ring formed by the connected spring tongues lies on the inside and thus shortens the clear width between the support points of the support ring.
  • the inner contour of the support ring is expediently at least triangular.
  • An equilateral triangle is suitable for increasing the rotational inertia. It is advantageous if the inner contour of the support ring is square. If the edges are also perpendicular to one another, particularly good stiffening of the corner regions is achieved.
  • the outer contour line of the support ring is circular. In this way, loads that attack strongly off-center, as can occur in the corner areas of rectangular support rings, are avoided.
  • This transition When designing the transition of the spring tongue into the support ring, it is advantageous for this transition to be accordion-shaped.
  • This fold-shaped or zigzag-shaped area can lie in the end region of the spring tongue and / or in the end region of the support ring. As a result, a deformation can be forced at this predetermined point in the region of the straight edges.
  • these areas can also be formed from a different material than the support ring or the spring tongue.
  • the zigzag-shaped area can be designed on one side on the top or bottom or on both sides like an accordion.
  • the spring tongues expediently have a V-shaped cross section, the angle of the transition between the end of the spring tongue and the support ring being in a range between 120 ° and 150 °. In principle, this angle can be in a range from 90 ° to 180 °.
  • the bends of the spring tongues are preferably directed towards one another inwards. It is also possible for the spring tongues to be linear, undulating, zigzag-shaped, directed inwards or outwards. In addition to the shape and orientation, different materials can also be used for the different spring tongues or support rings. Furthermore, the spring tongues or their sections can have different material thicknesses.
  • the cross section of the spring tongue has a taper at least at one point parallel to the straight edge of the spring tongue.
  • the spring properties can also be adapted to the stresses occurring and the compressibility of the spring element can be increased.
  • These material tapers are preferably provided in the center or in the third points of the developed length of the respective spring tongue.
  • a plurality of spring elements are stacked one above the other so that the straight edges lie one above the other.
  • the advantageous project Functionally congruent arrangement of the superimposed edges is achieved in that the fastening means provided on the support rings are positioned accordingly. This eliminates the need for time-consuming manual alignment of the adjacent spring elements.
  • the adjacent spring elements can also be arranged such that the edges of the support rings lie one above the other at an angle.
  • the foot element is plate-shaped and the spring element rests at least partially on a plate base of the foot element and is held laterally by a plate wall of the foot element.
  • the foot element fixed to a supporting structure e.g. slatted frame
  • a supporting structure e.g. slatted frame
  • constrictions of the support ring which are present, for example, on account of an outer circular and an inner rectangular outline, can be relieved by the plate wall lying over the circumference of the support ring.
  • the different support elements can have different numbers of spring bodies arranged one above the other and optionally have different spring constants. Furthermore, the spring elements can be stacked one on top of the other in such a way that a progressive spring constant distribution is created.
  • the invention is furthermore also suitable for forming a support device for a cushion pad with a plurality of support elements according to the invention, these being arranged at a distance from one another.
  • the arrangement of the support elements is adapted, among other things, to the shape of the cushion pad or to the level of the load to be absorbed.
  • the support elements can have a different number of spring bodies arranged one above the other and / or can be equipped with different spring constants. Adjacent support elements of the support device should in particular be arranged in such a way that the cover plates of adjacent support elements do not engage behind.
  • the spring element, support element and the device provided in the invention are particularly suitable for seating or lying surfaces and furniture devices provided therefor.
  • FIG. 2 shows a cross section of a support element with a cover plate, a foot element and three spring elements according to the invention in an undeformed state
  • FIG. 3 shows a partially sectioned perspective view of the foot element from FIG. 2.
  • the lateral edges 16 and 17 of the spring tongue 3 are free in the area between the support rings 7 and 8, ie in the area of the spring body 6, up to the straight edges 10 and 10 '.
  • the spring tongue 3 is thus in the area of the spring body 6 neither directly nor indirectly with the other spring tongues 2, 4 and 5 in operative connection or held laterally (ie horizontally) by other means.
  • An active connection between the spring tongues 2 to 5 only exists via the support rings 7 and 8.
  • the spring body 6 has four slots 22, 23 and 28, 29 which extend radially and over its entire height from the support ring 7 to the support ring 8, as a result of which the four spring tongues 2 to 5 are formed.

Abstract

L'invention concerne un élément de suspension (1) destiné à une base de rembourrage. Cet élément comprend un corps (6) comportant plusieurs languettes (2 à 5) disposées entre deux bagues de support (7, 8), lesdites languettes (2 à 5) étant reliées à ces bagues de support (7, 8). L'invention concerne également un élément de support (40) comprenant au moins un élément de suspension (1), une plaque de recouvrement (41) et un élément de base (42). La jonction entre une languette et une bague de support est conçue de façon à former une arête droite constituant une partie d'une ligne de contour de la bague de support, les bords latéraux de la languette étant libres jusqu'à cette arête droite. Ces arêtes droites permettent de définir clairement les zones de transmission de force pour dévier les forces d'appui de la bague de support aux languettes ou au corps de l'élément de suspension, ce dernier pouvant ainsi se déformer en des points prédéfinis et dans des directions prédéterminées. Dans un mode de réalisation préféré, la forme de la ligne de contour de la bague de support est déterminée essentiellement par les arêtes droites. Dans un autre mode de réalisation préféré, les languettes sont contiguës à la ligne de contour intérieure de la bague de support respective. Cet élément de suspension et cet élément de support peuvent être utilisés en particulier dans des zones d'assise et de couchage de meubles rembourrés.
