Definitions

• the invention relates to a wall for a furniture body with a recess which extends from a preferably flat end face of the wall into the wall and into which a fitting is inserted which guides a movable furniture part, in particular a furniture flap or a furniture door.
• the invention also relates to a method for producing such a wall for a furniture body.
• actuator arm drives To move flaps that close a furniture body, furniture fittings in the form of flap fittings (actuator arm drives) are already known, which are mounted on the inside of a side wall of the furniture body inside the same.
• These actuator arm drives generally have a spring-loaded energy accumulator and a transmission mechanism that actuates actuator arms, the free end of which is connected to a furniture flap and which, when opened, pushes it up against the force of gravity, thus making it easier for the user to open it.
• Such actuating arm drives are relatively large components and therefore restrict the space available inside the furniture body. The visual impression is not optimal either.
• the object of the invention is therefore to avoid the disadvantages of the prior art and to specify a wall and a method for its production, with which larger fittings, in particular flap fittings, but also door hinges with a greater installation depth, can be accommodated and also standard materials can be used for the wall.
• the wall should also be characterized by a visually appealing, uniform surface finish both on its outside and on its inside.
• This object is achieved by a wall, by a method for producing a wall, and by a furniture body and a piece of furniture with the features of the respective independent claim.
• the wall according to the invention is characterized by a recess milled from the front side into which the fitting is then subsequently inserted.
• a chain cutter is proposed in particular, the it allows a relatively deep and narrow recess to be made in the wall, the width of which comes close to the thickness (wall thickness) of the wall.
• Such chain cutters also called chain mortisers
• These are machine tools for machining (cutting) the material, with the chain cutter having at least one elongated, flat sword around which a revolving cutter chain is moved. This is driven by a motor, generally an electric motor.
• the milling chain itself carries the actual milling tool elements, namely protruding teeth or cutting edges on the individual chain links. These can also be reground.
• Chain cutters have so far mainly been used to mill wide mortises for tenon joints in wooden beams or relatively shallow pockets in lock cases (so-called mortise locks). According to the invention, it has now been recognized that such chain milling cutters are also suitable for milling exact recesses from the front side into the wall for a furniture body, with a relatively deep and narrow recess being able to be created which is in particular also capable of fitting a flap to drive a furniture flap. But larger fittings for doors can also be used in such larger recesses.
• FIGS. 1a, 1b and 1c show schematically the process steps of an exemplary embodiment of a process according to the invention, in which a recess is made in a side wall by means of a chain cutter.
• FIG. 2a shows a perspective view of such a side wall before the flap fitting is received.
• FIG. 2b shows the same perspective representation with a look inside, from which the shape of the recess can be seen.
• 2c shows a view of the end face of the wall according to FIGS. 1c, 2a and 2b.
• 2d shows a side view of the wall of the figures mentioned above.
• FIG. 3 schematically shows an alternative manufacturing method for making a recess in a wall from the front side.
• FIG. 4 shows an automatic mechanical embodiment, in particular for mounting the wall and for guiding the chain cutter.
• FIG. 5a shows an exemplary embodiment of a special chain cutter with two swords lying one above the other.
• Fig. 5b shows this chain cutter penetrating the wall from the front.
• 6a shows a furniture body with two exemplary embodiments of a wall according to the invention and one of two flap fittings before being inserted into the respective wall.
• 6b shows the process of inserting the flap fitting into one of the two walls.
• 6c shows a furniture body with both flap fittings used.
• 6d shows the furniture body with the two flap fittings and a furniture flap mounted on the flap fittings actuating arms.
• Fig. 1a one sees an essentially parallelepiped-shaped wall, which consists, for example, of wood or a wood-based material and is preferably a coated chipboard or an MDF board, as is typically used in furniture construction.
• the wall 1 preferably consists of one piece. This one-piece structure is also retained during the making of the recess by means of a chain cutter, which is described below. In contrast to the prior art, it is therefore not necessary here to construct the wall from several parts, for example from a core and two lateral cover surfaces. However, the term that the wall consists of one piece does not exclude the wall being, for example, a multi-layer panel before the processing according to the invention, which is supplied in this way from a panel factory. It is essential that no multiple parts are required to introduce the recess 7 .
• the chain cutter 2 has a drive housing with an electric motor and a protruding blade 4 around which a revolving cutter chain 5 is guided.
• this milling chain has individual links which carry a plurality of cutting edges, preferably made of hard metal (not shown here). These cutting edges are known per se and form the actual cutting milling tools.
• the chain cutter is moved linearly in and out of the wall 1 in a single direction (uniaxial), namely parallel to the upper or lower side edge and also parallel to the two flat side surfaces 1b.
• FIGS. 2a and 2b show a somewhat different exemplary embodiment of a plate with a somewhat larger recess than in FIGS. 1a to 1c, as is particularly suitable for accommodating flap fittings.
• FIG. 2b the geometric relationships of a preferred embodiment of a wall according to the invention (still without inserted fitting) are shown.
• the recess 7 has two parallel, lateral flat inner walls 7a, 7b, which are preferably parallel to the outer side surfaces 1b of the wall and preferably perpendicular to the end face 1a of the wall. This means that only a very thin residual wall 1c remains to the left and right of the recess, but this is sufficient to make the external appearance of the inside and outside of the wall 1 appear as if there were no recess 7 (see Fig. 2a ). Conversely, this thin remaining wall allows a relatively wide interior of the recess 7, so that larger flap fittings can also be accommodated.
• the recess 7 advantageously has two parallel, upper and lower, planar top and bottom walls 7c, 7d, which also preferably run perpendicular to the end face 1a of the wall 1. This results overall in a substantially cuboid recess 7, which is well suited for receiving fittings, which are typically also cuboid in terms of their external dimensions, in particular flap fittings.
• the recess 7 is rectangular in shape and it is preferably provided that this rectangular cross section extends over a large part at least 80% of the depth of the Recess 7 continues.
• the rear wall 7e also has a flat section 7e, which preferably runs parallel or slightly inclined, as will be seen in FIG. 2d, to the end face 1a of the wall 1.
• a curved section 7f that is not flat but is provided, which connects the wall surfaces 7c, 7d and 7e to one another or these wall surfaces merge into one another.
• This rounding comes from the front, rounded area of a typical chain cutter and is kept as small as possible in order to keep space restrictions for the fitting used, in particular the flap fitting, as small as possible.
• the recess 7 is designed in the manner of a blind hole and is closed on both sides except for the opening in the end face 1a of the wall 1, as shown, for example, in FIG. 2a.
• the external appearance of the wall 1 is not marred by the technical component of the fitting described in more detail below.
• the wall essentially looks like a normal wall of a furniture body or piece of furniture.
• exemplary dimensions of the wall 1 and preferred dimensions of the recess 7 are specified, as in the later Use of a fitting in the form of a flap fitting in the recess 7 are low.
• the wall 1 is initially a (coated) chipboard, MDF board or a board made of another wood-based material, which has a board thickness (thickness) D of 16 mm, which is typical in today's furniture construction.
• a board thickness (thickness) D of 16 mm
• panels with different wall thicknesses for example panels with a thickness of 19 mm, can also be used.
• the invention can also be implemented with very thin panels, namely panels with a panel thickness D of 16 mm.
• a recess 7 is milled using a chain cutter 2, as described above and described in more detail below, which leaves only a very small residual wall 1c with a wall thickness WS of between 1.5 mm and 3 mm, preferably at 2mm.
• a wall thickness WS of between 1.5 mm and 3 mm, preferably at 2mm.
• the greatest depth T of the recess 7 is at least 150 mm, preferably at least 200 mm and particularly preferably at least 250 mm.
• the width B of the recess 7 is between 10 mm and 16 mm, preferably around 12 mm.
• the height H of the recess 7 is between 80 mm and 160 mm, preferably around 120 mm.
• the recess is as narrow and deep as possible. Expressed in relative numbers means This means that the greatest depth T of the recess 7 is at least 15 times, preferably at least 20 times, greater than the width B of the recess 7.
• the greatest depth T of the recess 7 is at least 1.5 times, preferably at least 2 times, greater than the height H of the recess 7.
• the radius of the arcuate section 7f is 26.5 mm, for example. As already mentioned, it is mainly due to the front shape of the sword 4 of the chain cutter 2.
• FIG. 3 shows a further variant of the method step of making a recess 7 in the wall 1 by means of a chain cutter 2 .
• the height of the blade 4 together with the milling chain 5 is less than the height of the recess 7 that is ultimately achieved 1 is moved in and out from the end face 1a, but is also moved in the vertical direction according to the direction of the arrow 8 within the plate.
• the details vertical, height etc. relate to an orientation of the wall 1 in the vertical direction, just as the wall is also used when flap fittings are used as a side wall of a furniture body or a piece of furniture. It goes without saying that the plate can of course also be in other positions during production for manufacturing reasons and that the position information, vertical, height, etc., can change accordingly.
• the installation position of the finished wall with the recess and the fitting used can also change compared to the exemplary embodiments shown.
• a horizontal installation position of the wall is possible for a fitting that guides a door that can be pivoted about a vertical axis.
• the chain cutter 2 can be advanced along the linear guide 12 in the direction of the double arrow 11 (uniaxial), so that it penetrates the face 1a into the plate 1 and mills out the recess 7 there.
• the stops and/or holders 9 and the adjustment and movement mechanisms can be designed differently, in particular also be driven electrically, under computer control.
• the method according to the invention comprises not only the introduction of a recess 7 by means of a chain cutter 2 from the end face 1a, but also the subsequent introduction of a fitting 14 into this recess 7.
• This method step is shown in FIGS. 6a and 6b.
• the fitting 14 shown there is a flap fitting which is designed to guide a piece of furniture (in this case a furniture flap).
• 6a shows the flap fitting prior to insertion
• FIG. 6b shows the partially inserted flap fitting.
• 6c shows the completely inserted flap fitting.
• the front, rectangular frame 15 then rests flush against the front side of the recess 7 and covers the peripheral edges that run rectangular there.
• FIG. 6c shows that in the embodiment shown there there is not only one side wall, but a whole piece of furniture or a piece of furniture, which has two essentially identically designed side walls.
• a flap fitting 6 constructed in a mirror-inverted manner can be installed in the second side wall 6c.
• the flap fitting 14 itself has, in a manner known per se, a spring assembly 16 which forms an energy accumulator which drives at least one actuating arm 18 via a lever mechanism, gear wheels or a link control cam, to which a flap 17 can be attached, as shown in FIG. 6d .
• the actuating arm drive is designed in such a way that the gravitational force of the flap 17 is essentially compensated and the flap can be opened smoothly over the entire movement path.
• the spring force and the translation will preferably be designed in such a way that the flap remains in any position. Sections are also possible, however, in which the spring assembly actively drives the flap over a specific pivoting path, for example opening it completely or closing it completely.
• the subject of the invention is not only a method of manufacturing a wall and the wall itself, but also one formed with at least one such wall Furniture body or a piece of furniture, as shown purely by way of example with reference to FIG. 6d. Of course, other furniture can of course also be formed. It is also possible to use a door fitting in the manner described above instead of the flap fitting. Then the wall 1 is horizontal and the door pivots about a substantially vertical axis.
