Definitions

  • the invention relates to methods for producing boards of different thicknesses from wood or wood substitutes. This includes panels made from naturally grown wood as well as from extruded or molded wooden small parts or from other materials that can normally replace wood.
  • Such plates of different thicknesses are required, for example, in the furniture industry, in particular in the form of table tops, which should have bevels that weaken the wall in the edge area.
  • Such shaped panels are useful for ergonomic reasons, for example for work desks and desks.
  • the invention is based on the object. u n t e r s e d lic h ditKe panels made of wood or
  • the plate is composed of at least two layers, of which at least one layer is weakened in cross-section and tapered to change its thickness, after which the layers are provided with adhesive and pressed against one another on their mutually facing, inside-facing sides become.
  • At least one layer of an originally voluminous partial plate is formed by so-lifting shaping of channels lying parallel to one another, the webs located between the channels being shortened in whole or in part by machining oblique shaping.
  • the invention provides that the cross-section-weakened layer is subjected to bending deformation along wall-weakened areas when pressed with the other layer.
  • bevels should be provided with notches, notches in the area of the plate transition from normal to reduced sheet thickness transverse to their longitudinal axis, or broken through in some other way. In this way it is possible to deform the layer (partial plate) provided with bevelled webs in such a way that in the corner region of the plate there is a kind of ridge between the differently inclined bevels of the plate.
  • the cross section of the individual chip-shaped channel is adapted to half the cross section of a profile insertable in opposite channels.
  • Such profi can be used for different purposes according to the subclaims, for example for the purpose of armoring the plate or forming a fitting for a plug connection of adjacent plates, or to create a base for the introduction of threaded bores and similar connecting means.
  • Such usable profiles can be formed from a wide variety of materials, for example metal, with light metal profiles being particularly recommended. However, if it is a matter of firmly anchoring connecting elements, such as screws, then it is advisable to use profi le made of layered hardwood in the channels, whereby such profiles do not necessarily penetrate the channel, but only have short lengths in the area of the connection points need. Details of the invention emerge from the drawing. In it, the invention is shown schematically and for example. Show it:
  • Fig. (1) a cross section through a portion of a plate with a bevel.
  • Fig. (2) a cross section through two sub-layers, from which the plate according to Fig. (1) is composed.
  • Fig. (3) A partial top view of one of the layers acc. Fig. (2) with incorporated non-continuous channels,
  • Fig. (4) a plan view according to. (3) with channels arranged in part continuously,
  • Fig. (5) a perspective view of fluted plates, one of which is angled.
  • Fig. (6) a Dersc-ective view of the plates acc. (5) in the assembled state
  • Fig. 7 a personal view of two grooved plates
  • Fig. (8) a perspective view of the gem.
  • Fig, (7) fluted plates in the connected state
  • 9 shows a perspective view of a partial plate for the formation of adjoining bevels
  • Fig. (10) a perspective view of the molded and interconnected partial plates according to Fig. (9) and
  • Fig. (11) a perspective view of a plate with various proposals for the formation of reinforcements or fittings.
  • a partial cross section through a plate (1) is shown, which is to have a bevel (2) on at least one side.
  • the invention is based on the fact that this plate (1) is formed from at least two layers (partial plates) (3, 4), of which the layer (3), which contains the bevel (2), is weakened in cross-section and along the base plane ( 8) is connected to the other layer (4). It is of course conceivable to provide the other layer (4) with such a bevel (2) or to form the plate (1) from several layers. It is essential that the one which contains the bevel (2) is formed with a weakened cross-section and is therefore designed to be more deformable.
  • Layer (3, 4) consists, for example, of a solid wooden plate, in particular chipboard, into which channels (5) are machined.
  • the channels (3) are preferably arranged parallel to one another.
  • This processing has the consequence that the webs (6) along this milling plane (9) are shortened by machining.
  • the milling plane (9) according to FIG. (2) is brought into the basic plane (8) according to FIGS. (1) and (2) by deforming one or more of the partial plates (3, 4). It is easy to see that the partial plate (4) would also have to be deformed if it had a shortening of its webs (6) along a plane analogous to the milling plane (9).
  • bevels can also be guided around the corner of a plate (1). It is only necessary to provide the webs (6) with notches (13) or other grooves along the bending line, provided that the associated partial plate (4) has to be deformed along these notches (13).
  • a tubular profile (15) instead of a tubular profile (15), a cylindrical solid profile can also be used.
  • the profile can also be formed in the form of a rectangle (16) or a square (17).
  • a specially shaped profile for example an I profile (18) is also shown.

Abstract

Dans le procédé décrit, le panneau (1) se compose de couches (3, 4) dont au moins une (3) est affaiblie en section ainsi que chanfreinée et, après déformation en flexion, est liée à l'autre couche (4) par des techniques de collage et de compression. L'affaiblissement en section d'au moins une couche (3, 4) est réalisé par formage, par enlèvement de copeaux, de gorges (5) parallèles les unes aux autres; les parties intermédiaires (6) sont, aux endroits où le panneau (1) doit présenter des parois affaiblies (2), chanfreinées par usinage par enlevèment de copeaux selon un angle déterminé.
