  • Such parts can be, for example, panels, rods, bars, staves, or similar items.
  • the articles of furniture might be displayed as a whole in a store, it is impractical to transport them to a customer in an assembled state, especially if the articles are bulky.
  • the articles are transported to the customer in a disassembled state and then assembled from the individual parts on-site, either by trained personnel or by the customers themselves.
  • the individual furniture parts can be made from solid pieces of material, in particular from wood.
  • larger parts e.g., panels to be used for side walls or front pieces of the article, this results in very heavy parts, making transport and assembly more difficult.
  • such parts are expensive due to the amount of material needed, and their machining can result in a large amount of wasted or unused material.
  • a solid part can, e.g., be machined from a single piece of wood
  • the production of a frame as described above requires a larger number of individual pieces. For example, one rod might be needed for each side of the frame. Further, all of the pieces have to be carefully manufactured such that they fit together precisely. As such, producing and connecting the pieces requires more separate work steps than producing a solid part. Accordingly, it bears an associated higher risk for errors. Further, if a large number of identical frames is to be produced, the individual pieces should be identical for each frame, which can be difficult to achieve for large numbers.
  • the method comprises the following steps:
  • a hollow structure which extends along a longitudinal direction.
  • the hollow structure comprises a plurality of exterior walls, wherein each exterior wall extends parallel to the longitudinal direction.

In other words, the frame is completely separated from the remainder of the hollow structure after the cut is finished.

This makes the manufacture of the hollow structure easier, since boards shaped in a regular rectangular form can be used for the construction of the exterior walls, such boards being easy to produce and readily available.
  • the machining can comprise the provision of recesses inside the first frame and/or the first covering panel and/or the second covering panel. This way, mounting points for structural features of the final article of furniture, such as hinges or handles, can be provided.
