Definitions

  • the invention relates to upholstered furniture with a frame having at least one frame plate covered on the visible side with a flexible material, the at least one frame plate being padded with foam.
  • Such upholstered furniture can be beds, for example.
  • the frame of such a bed comprises at least one frame plate or is composed entirely of frame plates.
  • Such a frame encloses a mattress receptacle.
  • One or more mattresses are arranged in these.
  • Such a frame can be part of a so-called box spring bed.
  • Such beds often have a head plate as a frame part, which has a vertical height that is higher than the top of the mattress and in some cases is also wider than the side frame parts.
  • Such a head plate is often used as a backrest when a person using the bed wants to sit with their backs propped up. For reasons of comfort, such head plates are padded with foam as a frame plate.
  • Such a padded frame plate comprises a substrate - a plate that takes on the static support function, mostly a wooden panel, often made as chipboard - which is padded with foam on its visible or use side and covered with a flexible material, typically a textile.
  • a textile such a frame plate can also be covered with other flexible materials, such as artificial leather, leather or the like.
  • the foam padding also has a sound-absorbing function. This hampers the sound reflection on the substrate of such a frame plate used as a top plate. Since these frame panels of the frame of the upholstered furniture are typically components of relatively large dimensions, they also have a sound-absorbing property in the room in which the upholstered furniture is located. This is especially true for upholstered furniture in which all frame parts are designed as such frame panels. If this sound-absorbing or sound-absorbing functionality is in the foreground when designing the upholstered furniture, the flexible upper material should be a textile material.
  • the invention is therefore based on the object of developing upholstered furniture of the type mentioned at the outset in such a way that it has an improved soundproofing and / or soundproofing functionality.
  • this object is achieved by a generic upholstered furniture of the type mentioned at the outset, in which the foam upholstery of the at least one frame plate is provided by a foam layer, the surface of which facing away from the frame plate is structured by locally raised areas and areas recessed in relation to these, and the foam upholstery by means of a flexible tensioning track attached to the frame plate outside the visible area of the frame part is spanned in such a way that the locally raised areas are at least partially compressed in terms of their height and these compressed areas therefore have a smaller pore volume than the adjacent areas.
  • the foam upholstery of the at least one frame plate is provided by a foam layer.
  • This foam layer which is typically designed as a foam sheet, is structured on its surface facing away from the frame plate by a topography formed by locally raised areas and recessed areas.
  • the foam sheet itself is typically attached to the substrate of the frame plate by an adhesive bond.
  • the flexible property of the foam material is cleverly used to cover the foam layer with a flexible one Tension path to compress the locally raised areas at least somewhat, thus compressing them. Therefore, the flexible tensioning web covering the foam layer is covered with a certain tension over the foam layer in order to achieve this.
  • the locally raised areas of such a foam layer can be provided by knobs, which are typically arranged in the manner of a grid on the surface to be spanned by the flexible material are. Since the areas of the foam layer of higher surface density, those with the lower surface density, should not be too large, a grid dimension of such knobs of 0.3 to 2.0 cm is recommended for such a design of the foam upholstery.
  • composite foam panels made from foam flakes can also be used for the foam upholstery.
  • these On at least one of their flat sides, due to the typical manufacturing process due to the different foam flakes, these have a surface structure with raised areas and, on the other hand, recessed areas.
  • the foam flakes are made as a bed using a binding agent to create the bond between the foam flakes and are made as a plate.
  • the formation of a smooth surface is not possible. Therefore, the edge layer having this surface structure is normally cut off from a composite foam sheet produced in this way, in order to obtain a smooth surface for the intended use of such a composite foam sheet.
  • such a composite foam plate as produced, can be used.
  • the surface structure formed by the individual foam flakes represents an ideal surface for forming the foam layer with areas of higher surface density and areas of lower surface density distributed over the surface.
  • the use of such a composite foam sheet as a foam layer for realizing such a frame part is particularly favorable.
  • the use of such a composite foam layer improves sustainable management.
  • foam flakes can be used which have been obtained by recycling foam material.
  • such a composite foam sheet made of foam flakes of different types Density can be formed. This is provided in one exemplary embodiment, since it enables the sound-absorbing and sound-absorbing properties to be improved again.
  • Foam flakes with a size of typically 3 to 30 mm, preferably 10-25 mm, are used. In this way, the raised areas are also controlled with regard to their surface extension.
  • melt fibers are used which are mixed with the foam flake mixture and then applied to a base as bulk material before the foam flake-melt fiber mixture is heated to melt the melt portion of the fibers.
  • the use of melt fibers also supports sustainability, as these can also be recycled materials. Since when using melt fibers, the mixture does not necessarily have to be pressed into shape, melt fiber-based composite foam panels generally have a low spatial density, which also has an advantageous effect on the desired sound-absorbing or sound-absorbing properties.
  • the tensioning sheet has little, if any, elasticity.
  • the stretching sheet serves as protection for the foam layer if it is made from a composite foam sheet. This protection concerns the superficial cohesion of the foam flakes when the upholstery is used intensively.
  • the tensioning sheet prevents the fibers from piercing through it.
  • the tensioning track can be formed by the flexible material representing the upper material of the frame plate.
  • the tensioning web and / or the flexible material can also be recycled materials or can be produced using recycled products.
  • polyester is suitable for this, which can be obtained from recycled mattress covers in order to form the tensioning web or at least parts of the flexible upper material.
  • the flexible upper is typically a textile.
  • FIG. 1 shows a top view of a bed 1.
  • the bed 1 comprises a frame 2 as a bed frame.
  • Part of the frame 2 is a frame plate 3 which forms the head plate in the frame 2.
  • the frame plate 3 has a greater width than the bed 1 shown in its head end area and also a greater height than the upper end of the longitudinal frame plates 4, 4.1 and the upper end of a mattress holder 5 provided by the frame 2.
  • the frame plate 3 can be used for a seated person in the bed 1 can be used as a backrest.
  • the frame plate 3 comprises a wooden plate 6 as a supporting element (substrate), which in the illustrated embodiment is a chipboard is executed.
  • the wooden panel 6 is padded on the visible side and thus in the direction of the mattress holder 5, specifically by a foam layer 7.
  • the foam layer 7 is guided around the longitudinal edges to over the narrow sides of the wooden panel 6.
  • the foam layer 7 is covered with a tensioning strip 8, which in this exemplary embodiment also represents the upper material.
  • the foam layer 7 is provided by a composite foam sheet.
  • the composite foam board is made from recycled foam flakes with melt fibers as an incorporated binder.
  • Figure 2 shows in a production step in a schematic, enlarged detail view of the foam layer 7 attached to the wooden plate 6 by means of an adhesive 9.
  • the foam layer 7 which in the illustrated embodiment has a thickness of about 1 cm, the one pointing away from the wooden plate 6
  • Surface 10 is structured by raised areas 11 and, on the other hand, recessed areas 12. This structuring is formed by the pouring of the foam flake-melt fiber mixture.
  • the composite foam sheet forming the foam layer 7 has been produced from foam flakes of different densities.
  • the tensioning web 8 is stretched over the foam layer 7 and covered with it.
  • the raised areas 11 are compressed, whereas the recessed areas 12 are not compressed.
  • the tensioning force applied by the tensioning track 8 is set in such a way that the near-surface edge region of the foam layer 7 is not uniformly pressed in and thus compressed.
  • the surface 10 is smoothed (see Figure 3 ).
  • areas 13 of higher density are formed in this near-surface edge cut of the foam layer 7.
  • FIG Figure 3 shown schematically.
  • the sound-receiving surface 10 of the foam layer 7 is non-uniform in terms of its density, specifically in accordance with the arrangement or distribution of the raised areas 11 on the surface 10.
  • Such a design of the foam layer 7 improves the sound-absorbing and sound-absorbing properties of the frame plate 3.
  • the tensioning track 8 is attached to the rear side 14 of the wooden panel 6 with clips 15.
  • the focus is on the creation of a near-surface edge layer of different density and thus porosity.
  • compression only of the raised areas is addressed.
  • a density difference between the originally raised areas and the originally recessed areas also results if the raised areas and to a certain extent also the non-raised areas are compressed.
  • the tensioning band 8 is covered with the desired upper material. This is stretched over the tensioning strap and, like the tensioning strap, attached to the back of the wooden panel.
