Definitions

  • the present invention relates to a supporting frame for a piece of furniture, wherein the supporting frame comprises at least one outer side.
  • the invention relates to a piece of furniture comprising a supporting frame, a method for manufacturing a supporting frame as well as a use of a supporting frame.
  • a supporting frame for a piece of furniture such as a chair, a table and a piece of corpus furniture
  • the supporting frame is manufactured of several individual side pieces, wherein the ends of the side pieces, via dowels and glue, are assembled with furniture legs, and wherein the supporting frame is stabilized by inner corners, wherein the corners are screwed into the furniture legs and attached to the side pieces, for instance with glue, and wherein fittings are mounted internally in the supporting frame for use at mounting of for instance furniture seats, tabletops and corpus.
  • a supporting frame for a piece of furniture wherein the supporting frame comprises an outer side and is made in a continuous material.
  • the object of the invention is to improve the manufacturing of products, so that it will be both faster, easier and cheaper to manufacture a supporting frame, whereby productivity, competitiveness and eventually finances will improve. Moreover, the object of the invention is to make a stronger supporting frame, which both strengthens and stabilizes the supporting frame further, and finally the object of the invention is to broaden the range of materials applicable for use for a supporting frame.
  • the basic idea is to go from several separate sides to one single piece of wood, which is continuous from the onset of the manufacturing of the supporting frame, wherein the wood for instance is constituted by a block of plywood, which is subsequently milled out as a solid base.
  • the veneer can for instance primarily consist of birch or spruce, which grow fast, are cheap, less strong but very available compared with for instance oak, and secondarily the veneer can consist of for instance a little oak, which grows slowly, is expensive, very strong but less available compared with birch or spruce.
  • Other compositions of veneer is of course also possible, just as other materials, such as plastic composites with and without fibres can also be used.
  • the object of the invention is to provide a piece of furniture comprising a supporting frame, a method for manufacturing a supporting frame as well as a use of a supporting frame.
  • the object stated above is achieved with a supporting frame, as initially described, wherein the supporting frame is made out of one continuous piece of material, and wherein the supporting frame comprises several layers, wherein each layer comprises one and the same single continuous piece of material in the entire extent of the layer and wherein each individual layer is contiguous with at least a second layer.
  • a supporting frame was typically assembled of several parts in the circumference of the supporting frame, and wherein several side pieces were for instance assembled via dowels and glue.
  • Prior art typically comprises four side pieces, which are joined together as mentioned.
  • the new solution moreover means that a supporting frame can be faster, easier but also cheaper to manufacture, as a supporting frame can for instance be made out of solid wood or a block of plywood, which is subsequently milled out for a supporting frame.
  • a supporting frame can lead to savings of as much as 50% of the mounting time for a piece of furniture relative to the mounting time for common supporting frames.
  • the material properties of the supporting frame will be approximately identical in two directions, as plywood is made of thin layers of veneer that is glued together with the grain directions crosswise.
  • Another possibility of obtaining identical material properties could be manufacturing a supporting frame in a plastic composite material, for instance with glass, aramid or carbon fibres for additional strength.
  • a supporting frame can also be manufactured as mentioned in a hybrid material, which could consist of one or more layers of wood and one or more layers of another suitable material, including plastic - fibre- reinforced or not, metal and other suitable material.
  • a supporting frame can also be constructed by a number of layers of ready-made plywood boards.
  • the basic element of a supporting frame can be manufactured of five layers of plywood board, wherein each layer has a thickness of for instance fifteen millimetres.
  • the individual layers of plywood board and/or veneer layers can have similar or dissimilar thickness.
  • a supporting frame can be constructed by a number of layers of plywood or layers of veneer or other suitable material, and the supporting frame itself can be executed as prestressing and may thus be curved in one or more directions.
  • One example could be a supporting frame for a chair, wherein the top edge as well as the bottom edge have the same curved shape, wherein the top edge is for instance concave, while the bottom edge is convex, which offers even more design options.
  • the present invention also relates to a supporting frame, wherein the supporting frame further comprises a bottom, wherein the bottom comprises one and the same continuous piece of material.
  • said bottom can visually shield from construction details in the supporting frame itself.
  • Such bottom can advantageously be arranged at the bottom part of the supporting frame, at the top part or in principle at any point between the top edge and the bottom edge of the supporting frame. The visual shield is obviously not obtained to the same degree, if the bottom is at the top edge of the supporting frame.
  • the supporting effect of the supporting frame itself is obtained regardless of where at the supporting frame, the bottom is arranged.
  • this bottom can in principle constitute the seat of a chair or the top of a table.
  • the bottom can have a size corresponding to the outer dimensions of the supporting frame, but also a size, wherein the bottom extends beyond one or more sides of the supporting frame for instance beyond all the sides.
  • the bottom can advantageously be manufactured in one continuous piece, but can also be perforated or have one or more major cut-outs. Partial presence of such a bottom will alone lead to increased rigidity in the construction of the supporting frame.
  • the present invention also relates to a supporting frame, wherein the supporting frame further comprises at least one mounting ear for use in mounting of other furniture elements.
  • Mounting ears will preferably be arranged so that they are hidden within the supporting frame, if the supporting frame is solid, the entire supporting frame can constitute a mounting ear, but mounting ears could for that matter also be placed on the outer side of the supporting frame. In the mounting ears, a pocket hole or a through-going hole can be drilled. Mounting ears, or in this case probably rather mounting holes, can moreover be arranged in the supporting frame itself.
  • the present invention also relates to a supporting frame, wherein the supporting frame on its outer side further comprises leg recesses. This makes it possible to place the desired number of legs on the supporting frame.
  • the present invention also relates to a supporting frame, wherein the supporting frame on its outer side in the leg recesses comprises at least one screw hole.
  • the supporting frame can further comprise at least one dowel hole, wherein a dowel can be mounted for additional support and stability of the leg and supporting frame assembly.
  • leg recesses other types of means for joining legs to the supporting frame can be formed, including for instance a groove joint with fixed or loose tongue.
  • the present invention also relates to a supporting frame, wherein the supporting frame can also be manufactured of plywood, plastic composite material with for instance glass, aramid or carbon fibres or a hybrid material, which could consist of one or more layers of wood and one or more layers of another suitable material, including plastic - fibre- reinforced or not, metal and other suitable material.
  • the present invention also relates to a piece of furniture, wherein the piece of furniture comprises at least one leg and at least one of the following: seat, tabletop, drawer and corpus.
  • the present invention also relates to a method, wherein the method comprises the following steps:
  • A One and the same single continuous piece of material is roughly adjusted to at least the outer measures of the supporting frame
  • the supporting frame is finely adjusted to at least the outer measures.
  • the present invention also relates to a method, wherein the method comprises the following step between A and C:
  • each layer comprises one and the same single continuous piece of material in the entire extent of the layer and is joined with at least a second layer
  • the present invention also relates to the use of a supporting frame for a piece of furniture, such as a chair, a table and a piece of corpus furniture.
  • a solution is obtained consisting of only a single element unlike a traditional solution, wherein four different supporting frame sides, four corner fittings (often different due to angles etc.) are used as well as a number of angle braces, which are fixed with screws partly to the inner surface of the supporting frame and partly to another furniture element.
  • a substantial simplification and hence a substantial reduction of mounting time are obtained.
  • larger rigidity and generally increased strength and robustness are obtained in a supporting frame.
