Definitions
- the invention relates to a flat cushion body consisting of at least one grid plate made of resilient material with a plurality of grid webs delimiting grid openings at the edge.
- the grid plate has a flat basic design, and the cushioning or spring action of the cushion body in the event of a load is based on a compression deformation of the resilient material, in which known case foam, preferably foam rubber, essentially only at the crossing points, with high peak voltages due to kinks in the foam, which quickly lead to destruction.
- foam preferably foam rubber
- the invention has for its object to provide a flat cushion body of the type mentioned, which has an excellent spring action with excellent ventilation and has a long life.
- the grid plate is designed as a corrugated profile body with grid webs passing through the wave extremes of its wave contour, at least a large part of which are spaced apart from one another transversely to at least one direction of wave propagation.
- the cushioning material there is no compression deformation of the cushioning material, which proves to be unfavorable for the service life of the cushioning body, but rather a predetermined limited bending deformation of the grid plate takes place according to the invention due to its design as a corrugated profile body, in which the grid webs are largely independent in the manner of individual bending springs can be deformed from each other.
- the cushion body according to the invention has spring properties which are distinguished by a high degree of point elasticity.
- the wave contour ensures a favorable stress curve and a uniform absorption of the deformation work in the upholstery material, which favors the long life of the upholstery body.
- the cushion body according to the invention can comprise two or more such grid plates in a layered arrangement, the upper grid plate with its lower wave extremes (wave minima) the upper wave extremes (wave maxima) of the next lower grid plate is supported.
- lattice plates with a wave propagation direction offer themselves, the wave crests and valleys of which are largely formed by lattice webs running longitudinally to them.
- the grid plates are alternately superimposed with directions of wave propagation that are orthogonal to one another, so that the grid webs running in wave crests and troughs each cross in pairs. Even when the grid plates are stretched due to the load, they offer enough leeway so that the support engagement of the grid webs is always retained.
- grid plates which are in support engagement standing bars can be fixed to each other by material or form locking are trained.
- Lattice bars can create point-like areas in wave crests and form valleys that are exactly opposite in pairs when stacked.
- grid plates can also be used for this, the wave contour of wave propagation is shaped in two different directions. The then punctiform wave extremes are traversed by grid webs and come along Stacking several grids in support engagement where they are against each other be fixed.
- Fig. 1 is shown as a flat cushion body as a whole with 1 grid plate with a rectangular upholstery surface in plan view.
- the grid plate 1 consists of resilient material such as, in particular, elastomeric material, possibly with fiber inclusions, and comprises grid webs 2 and 3 in a uniformly repeating pattern which delimit a large number of grid openings 4 on the edge.
- the grid plate 1 is designed as a corrugated profile body with grid webs 2 passing through the wave extremes of its wave contour.
- the wave extremes are formed by wave crests 5 and wave troughs 6 of a wave contour with a wave propagation direction, constant wall thickness and the same wavelength from top 7 and bottom 8 of the corrugated profile body.
- the lattice webs 2 each extend over sections of the wave crests 5 and troughs 6 in their longitudinal direction. At the end, the lattice webs 2 open into the lattice webs 3, each forming a node 17, which extend in the direction of wave propagation.
- the mutual, constant, each running continuously over almost an entire wavelength - that is, connection-free - transverse distance between adjacent, parallel to each other over the entire length of the grating plate 1 in the wave propagation direction 3 defines a longitudinal distance between adjacent grating webs 2 transverse to the direction of wave propagation, whereby the stiffening effect of the corrugated profile shape perpendicular to the direction of wave propagation largely canceled and a high point elasticity of the grid plate 1 is achieved.
- the longitudinal distance between adjacent grating webs 2 is equal to the transverse dimension, based on the direction of wave propagation, of the grating openings 4.
- the pattern of the bars 2 and 3 forms, seen in plan view, a two-way pattern.
- the repeat length is the simple thing or a whole multiple of the wavelength.
- the wavelength can be used instead the single or a whole multiple of the repeat length.
- the repeat length and the wavelength is the same in both directions.
- the lattice webs 2, 3 passing through the wave extremes are shaped and arranged in such a way that when the lattice plate 1 is turned by rotating about one of the two central axes 16 in its central plane 16 by 180 ° wave minima and wave maxima, they alternate with one another, seen in plan view, congruently.
- wave maxima and wave minima come to an alternate pair, as seen in plan view, in part.
- the lattice webs 2 between the adjacent lattice webs 3 are each offset in the center.
- the lattice webs 2 are extended by lugs 9, which extend beyond the respectively adjacent lattice web 3 and are directed towards one another.
- the lugs 9 reduce the longitudinal distance between two crosspieces 2, which, when loosely stacking several crossplates 1 with intersecting wave crests 5 and troughs 6, increases the permissible tolerance for mutual displacement, in which the support engagement between two crosspieces is still guaranteed and therefore no fixation the grid webs 2 is required.
- the lugs 9 correspond to lugs 9 'which start from the edge 10 of the grid plate 1, which, like the other three edges of the grid plate 1, is kept free from grid openings 4.
- the thickness of the lattice webs 2, 3 can also have different dimensions in the direction of wave propagation. As a result, successive zones of different spring hardness or bending stiffness of the grid plate 1 can also be produced in the direction of wave propagation.
- a grid area 3 shows a first area A with a given web thickness, to which an area B with a reduced web thickness and a correspondingly increased wave amplitude of the wave contour adjoins, so that the wave profile of the grid plate 1 regardless of such differences has a constant overall height in the web thickness.
- the peak voltages can be reduced by varying the thickness of the grid webs 2, 3 and the deformation work can be distributed evenly.
- the grid plate 1 has the same basic pattern of the grid webs 2 ′ and 3 delimiting the grid openings 4.
- the wave contour of the grating plate 1 is characterized by wave propagation in two different directions, the grating webs 2 ', 3 each passing through the wave extremes at one point. Due to this wave contour with two different wave shapes that run horizontally to one another in the example shown, the grid plate 1 is designed in the manner of an egg carton. When the grid plate 1 is rotated about one of its central axes 16 by 180 °, wave maxima and wave minima, viewed in plan view, each completely or partially mutually congruent.
- the nodes 17 are in the areas 18 of the wave extremes designed so that they are cohesive there at the respective layering several grid plates 1 with them in support engagement grid webs 2, 3 of the adjacent grid plate 1 can be fixed.
- FIG. 13 shows a similar exemplary embodiment of the invention in detail with lattice webs 2 "', 3""' passing through the wave extremes.
- FIG. 7 illustrates, on the basis of a section of the grating plate 1, a top view of an embodiment in which the grating webs 2 extending over partial lengths of the wave crests 5 and troughs 6 open at the end into lattice webs 3 ′, which extend obliquely to the direction of wave propagation. All of the grating webs 2, 3 'adjacent to the direction of wave propagation are each spaced apart in this direction continuously over almost an entire wavelength, so that the pairs of grating webs 3' forming the individual spiral springs can largely deform independently of one another. This results in a high point elasticity of the grid plate 1.
- the grid webs 2 form here with the grid webs 3 'on both sides in each case a pair of grid openings 4', which have the basic shape of isosceles triangles in plan view.
- the pairs of triangles or lattice openings 4 ' are offset in the longitudinal direction of the wave crests and valleys 5, 6 from one another in the manner shown in FIG. 7 and are nested one inside the other.
- the longitudinal distance between the in the longitudinal direction of the wave crests and valleys extending webs 2 is in this embodiment of comparatively narrow opening gaps 11 formed between the individual webs 2.
- the design of the grid plate 1 according to FIG. 7 offers a maximum tolerance towards Displacements of two superimposed grid plates 1. By a total longer web lengths this embodiment reacts softer.
- the upper grid plate 1 which in the example shown is equilateral, is shown rotated by 90 ° about a vertical axis.
- the upper grid plate 1 with its lower wave extremes, the grid webs 2 running in the longitudinal direction of the wave troughs 6, on the upper wave extremes, the grid webs 2 running in the longitudinal direction of the wave crests 5, is the next lower grid plate 1 supported each other in the middle, as can be seen in particular from FIGS. 2 to 4.
- the predetermined mutual position of the individual lattice panels 1 can be maintained by mutual mutual fixation, as illustrated by the edge-side fastening points 14, via material or form-fitting.
- the axis 15 here is the bisector through a corner point.
- the upholstery body has an upholstery surface which, when viewed from above, has an outer shape which is invariant with respect to rotation by at least a certain angle - for example 90 ° for a square - the stacking of individual grating plates 1 with only one direction of wave propagation can result in an upholstery body with one single, identical shape of the grid plate 1 can be brought about by coordinated pattern selection and offset to the edge.
- Such shapes are, for example, a circle or an equilateral polygon.
- two different forms of the grid plate 1 are required to form a cushion body with a plurality of stacked grid plates 1 according to FIG. 8, in which the wave propagation directions are at right angles can run to each other.
- FIGS. 9 and 10 show two exemplary embodiments of a grid plate 1 with a wave propagation direction and, compared to the previous exemplary embodiments, curved grid webs 3 "and 3"', respectively.
- the stretching in the direction of wave propagation which occurs when the grating plate 1 is loaded due to the wave profile being laid flat is compensated for by upsetting the arc-shaped grating webs 3 "or 3"'extending in the direction of wave propagation, so that the displacement of two grating plates 1 lying one above the other is reduced.
- This allows the realization of larger wave amplitudes with greater rigidity and greater spring travel and thus higher cushion bodies with the same number of grid plates 1, which leads to a reduction in the total costs.
- the spring action is softer due to the arcuate lattice webs 3 "or 3"'due to the increased length of the spiral springs formed by the lattice webs 3 "or 3"'.
- FIG. 11 and 12 show two exemplary embodiments of a grating plate 1 according to the invention, which can originally be produced from corrugated profile plates with a wave propagation direction, but after introducing the grating pattern with punctiform formation of the wave extremes, several wave propagation directions - in FIG. 11 three, in FIG. 12 four - show.
- the grid bars 2 "and 3" "or 2" 'and 3 ""' form nodes 17 in which they cross orthogonally. All of them transverse to the direction of wave propagation - that means here in the direction of the original wave crests 5 and wave troughs 6 - Adjacent to each other the bars 2 "and 3" "or 2" 'and 3 ""' are transverse to Wave propagation direction consistently over almost an entire wavelength spaced from each other, their in these embodiments Distances in this direction are not - as in the exemplary embodiment according to FIGS. 1 to 6 a wavelength constant, but according to the shape of the grid bars 2 " and 3 "" or 2 "'and 3" "' are different.
- the grid webs form when passing through an extreme wave 2 ", 3" “or 2” ', 3 “”' in the area 18 circular widenings on which they are stacked two or more grid plates 1 come into support engagement and cohesively on the lattice webs that come into support engagement with them 2 ", 3" "or 2" ', 3 ""' of the adjacent grid plates 1 by, for example, adhesive or welding can be firmly fixed.
- the nodes 17 each lie between the areas 18.
- the pattern of the lattice webs 2 ", 3"" is chosen so that when mirroring at the central axes 16 of the upholstered surface chosen here as an example, the areas 18 lie one above the other, so that a multi-layered upholstered body with only a grid plate 1 can be realized by turning this grid plate 1 in the following position around the central axis 16 by 180 °, as a result of which the troughs 6 of the upper grid plate 1 come into support engagement with the wave crests 5 of the lower grid plate 1 in their areas 18 and there can be fixed to each other.
- the nodes 17 are arranged in areas 18 of the wave crests 5 or wave troughs 6. There, when two or more grid plates 1 are layered one on top of the other, they can be fixed cohesively to the grid web 2 "', 3""' of the neighboring grid plate 1 that comes into support engagement with them.
- Two central axes 16 of two possible are again exemplary the section of FIG. 12 forming grid plates 1 marked.
- the central axes 16 are congruent with the areas 18, so that according to FIG. 11 when turning a grid plate 1 by rotating about a central axis 16 by 180 ° Areas 18 of the wave crests 5 of the lower grid plate 1 with the areas 18 of the Troughs 6 of the upper grid plate 1 come into support engagement and cohesively are fixable to each other.
- the arcuate lattice webs 2 "', 3" “' reduce the expansion the grid plate 1 when loaded by flattening its wave contour by can be compressed by bending to reduce the radius of the arc.
- the bars 2 "', 3" "' pass through the wave extremes by they open into one another at the end to form a node 17.
- Your end point is four grid bars 2 "', 3" "' in common and is at the same time in a wave extreme arranged node 17.

Bei Drehung um die zu ihrer Mittelebene orthogonal und zu ihren Außenbereichen mittig verlaufende Achse 19 um 90° oder 270° kommen Wellenmaxima und Wellenminima jeweils wechselseitig paarweise, in Draufsicht gesehen, teilweise zur Deckung.
Gegenüber der Darstellung in Fig. 1 ist die obere, bei dem dargestellten Beispiel gleichseitige Gitterplatte 1 jedoch um 90° um eine Hochachse gedreht dargestellt. Bei dem dargestellten Beispiel mit insgesamt fünf übereinandergeschichteten quadratischen Gitterplatten 1 ist die jeweils obere Gitterplatte 1 mit ihren unteren Wellenextrema, den in Längsrichtung der Wellentäler 6 verlaufenden Gitterstegen 2, auf den oberen Wellenextrema, den in Längsrichtung der Wellenkämme 5 verlaufenden Gitterstegen 2, der nächstunteren Gitterplatte 1 einander mittig kreuzend abgestützt, wie dies insbesondere aus den Fig. 2 bis 4 ersichtlich ist.
