[0102] FIGS. 21 to 23 represent cross-sections according to the lines XXI-XXI, XXXIII-XXXIII indicated in FIG. 20;

[0103] FIGS. 24 and 25 represent possible finishing processes of the method from FIG. 20; and

[0104] FIG. 26 represents a drawer which is obtained according to the method illustrated in FIG. 20.

[0105] In FIGS. 1 to 3, a drawer 1 is represented which is realized in accordance with the first aspect of the invention. Herein, the drawer 1 comprises at least a front wall 2, a rear wall 3 and two sidewalls 4-5, as well as a bottom 6.

[0106] In accordance with the first aspect of the invention, the rear wall 3 is connected to the sidewalls 4-5 by means of mutually cooperating locking profiles 7-8, whereas the front wall 2 is connected to the sidewalls 4-5 by means of connection means 9 other than locking profiles.

[0107] In the represented example, the locking profiles 7-8 respectively consist of a tongue 10 and a groove 11, which are provided with respective locking parts 12-13, which, in the final position, prevent or at least counteract that the tongue 10 comes out of the groove 11. In the represented example, the tongue 10 is split. Applying a gap 14 in the tongue 10 is useful in particular when it is required that the tongue 10 can be pushed into the groove 11 by means of a snap movement, as this promotes the elasticity of the tongue. According to a not-represented variant, use can also be made of solid tongues, thus, without the represented gap.

[0108] The profiles 7-8 of the represented example allow joining together the sidewalls 4-5 and the rear wall by means of an angling movement as well as a snap movement.

[0109] In the represented example, the connection means 9 between the front wall 2 and the sidewalls 4-5 consist of separate connection elements 15, which cooperate with openings 16-17, more particularly bore holes, which are provided in the rear side 18 of the front wall 2 and the narrow ends 19 of the side walls 4-5. In the example, these connection elements 15 are formed by dowels, more particularly mechanically locking dowels. In FIG. 2, to this aim dowels with a ribbed surface, more particularly a surface 20 ribbed in barb-shape, is applied.

[0110] As explained in the introduction, other connection means can be applied as well.

[0111] As becomes clear from the figures, the drawer 1 can be designed such that the only locking profiles which are present there are the ones required for the connection between the rear wall 3 and the sidewalls 4-5, whereas for the remaining connections, exclusively use is made of bore holes or other treatments which can be performed in a bore line, in which then separate attachment elements can be provided, all this possibly supplemented by simpler profiles, such as grooves 21 for providing the bottom.

[0112] Also, the following characteristics can be seen in the figures:

[0113] The locking profiles are laterally insertable, such by means of an angling and/or snap movement; [0114] the front wall consists of only one wall part, which thus also forms the front part of the drawer; [0115] the front wall is made as a front panel, which, with its rear side, is turned towards the narrow front ends of the sidewalls; [0116] the rear wall is situated between the sidewalls; [0117] the sidewalls are provided with openings and/or recesses 22 for attaching fittings, more particularly for attaching thereto parts of a fitting mechanism for retractably supporting the drawer.

[0118] In FIG. 4, a drawer 1 is represented which forms an example of the second aspect of the invention. As represented, the drawer 1 comprises a front wall 2, a rear wall 3 and two sidewalls 4-5, as well as a bottom 6. Further, both sidewalls 4-5 are connected both to the front wall 2 and the rear wall 3 by means of profiles, which fit into each other in a locking manner and which use a tongue 10 and groove 11 with locking parts 12-13, wherein these profiles can be inserted laterally into each other. The particularity consists in that the front wall 2 is attached directly to the sidewalls 4-5 and that the connection between the front wall 2 and the sidewalls 4-5 is achieved in that the respective tongues 10 are provided distally on the foremost ends of the sidewalls 4-5, wherein these tongues 10 are realized as solid tongue profiles and thus not split, wherein the respective grooves 11 are situated on the rear side of the front wall 2, and wherein the tongues 10 fit into the respective grooves 11 by means of an angling movement A of the sidewalls. It is clear that in this manner a rigid connection between the front wall 2 and the sidewalls 4-5 can be realized, by which the front is attached to the remainder of the drawer 1 in a particularly stable manner.

[0119] In FIG. 5, the method according to the third aspect of the invention is illustrated. As already mentioned in the introduction, it relates to manufacturing drawers, wherein the drawers 1 comprise at least a front wall 2, rear wall 3 and two sidewalls 4-5, as well as a bottom, and wherein the two sidewalls 4-5 as well as the rear wall 3 comprise profiles which fit into each other in a locking manner, and which to this aim make use of a tongue 10 and groove 11 with locking parts 12-13, wherein these profiles can be inserted laterally into each other, and wherein the groove 11 respectively is provided on the interior side of a sidewall. As FIG. 5 represents, the particularity of the method consists in that at least two sidewalls 4-5 are manufactured of one board 23, respectively; that herein, the grooves 11 are realized by means of a continuous treatment, whether or not consisting of a plurality of partial treatments, such as milling cycles; and that only afterwards said board is subdivided into two or more sidewalls. Subdividing is performed according to the represented line 24, for example, by means of a saw treatment.

[0120] This results in the advantages mentioned in the introduction.

[0121] The two sidewalls 4-5 preferably are the ones which are intended to form part of one and the same drawer 1.

[0122] Further, for realizing connections with the front wall, openings 17, such as bore holes, can be provided in the board 23 before the latter is sawed.

[0123] Obviously, the method is particularly suitable for realizing drawers according to the first aspect.

[0124] FIGS. 6 to 8 illustrate the fourth aspect of the invention, this applied to the component parts of a drawer. As an example, in FIG. 6 a front of a drawer 1 is represented, with two locking groove profiles 25 on the rear side, to which sidewalls 4-5 can be coupled, wherein the groove profiles 25, at least at one of their ends 26, are discontinuous. Further, it is represented in full line that such groove profile 25 can also be made discontinuous on the other end 27, or, according to an alternative, which is depicted in dashed line, may be continuous indeed.

[0125] The particularity herein consists in that the groove profile 25 is realized by one or more cuts by means of one or more rotating cutting tools which engage in the surface from the exterior, wherein the cutting tool and the respective panel-shaped element, in mutual respect, perform a pass-through movement in the longitudinal direction of the cut, as well as is locally moved in and/or out of the surface of the panel-shaped element in order to form said end.

[0126] The cuts preferably are realized by means of saws or saw cutters.

[0127] FIG. 7 represents an embodiment wherein the groove profile 25 is realized by means of two cuts 28-29. FIG. 8 represents a second embodiment wherein the groove profile is realized by only one cut 30. By pushing the cutting tools applied therewith locally into the panel-shaped elements and/or lifting them out of them, then locking groove profiles, which are finite at least at one end, can be realized in a pass-through operation and thus in a very efficient manner.

[0128] In FIG. 9, an example of the fifth aspect of the invention is represented. According to this aspect, this relates to a drawer 1 which comprises at least a front wall 2, more particularly a front panel, two sidewalls 4-5, as well as a bottom 6, with the characteristic that the drawer comprises a fitting part 31 which forms part of or which directly cooperates with a guiding mechanism 32 for retracting the drawer, wherein this fitting part 31 is attached, on the one hand, to a sidewall 4-5 and, on the other hand, also provides for a connection with the front wall 2, more particularly the front panel. It is clear that the front panel consequently obtains an additional function, which leads to a stable and advantageous assembly.

[0129] The guiding mechanism 32 is represented only schematically in the form of fitting parts, namely first fitting parts 31, which are attached to the drawer, and second fitting parts 33, which are fixedly attached to a piece of furniture. The portion present in between these can be of any kind and, for reasons of schematization, is omitted from the figure. By way of example, the portion present in between may consist of a telescopic system, a ball-bearing running system, and so on.

[0130] The fitting parts 31 can be attached to the drawer, in particular to the sidewalls 4-5, in any manner, either by means of screws or in another manner. In the example, these fitting parts are situated laterally against the sidewalls 4-5; however, it is clear that, according to a variant not represented here, they can also be mounted, for example, underneath the sides 4-5.

[0131] The attachment between the front wall 2 and the fitting parts 31 can also be realized in any manner. In the represented example, to this aim the first fitting part 31 is provided with forward-directed protruding portions 35, onto which the front wall, more particularly the front panel, can be attached in that the portions 35 cooperate with openings 16, for example, via clamps, glue, etc.

[0132] In the example, the sidewalls 4-5 are connected to the rear wall 3 by means of film hinges 36. However, other kinds of connections are not excluded here. According to a not represented embodiment, instead of film hinges use shall be made of coupling means which are formed by mutually engaging profiles, for example, such as in FIG. 2.

[0133] In FIG. 10, schematically some more possibilities of the sixth aspect of the invention are represented. Herein, this relates to a drawer construction with a drawer 1, which comprises at least a front wall 2, rear wall 3 and two sidewalls 4-5, as well as a bottom 6, with the particularity that the drawer construction combines at least the following characteristics: [0134] the front wall 2 is connected to the sidewalls 4-5 by means of mutually cooperating locking profiles, more particularly profiles which fit into each other laterally, preferably by means of an angling movement; [0135] the rear wall 3 is connected to the sidewalls by means of connection means 37 other than locking profiles; [0136] the drawer is movably supported via a fitting mechanism, more particularly guiding mechanism 38.

[0137] In the example, the rear wall 3 is situated between the sidewalls, and the rear wall 3 is connected to the sidewalls by means of coupling means which allow attaching the sidewalls laterally onto the distal ends of the rear wall, in this case by means of dowels 39.

[0138] The fitting parts 31 are attached to the sidewalls 4-5 and movably supported in respect to the fitting parts 33 which are intended for being fixedly attached to a piece of furniture.

[0139] As the fitting parts 31 usually are positively supported laterally by the fixed fitting parts 33, it is obtained that, as soon as everything is assembled, at least a certain lateral support is given to the sidewalls 4-5, which prevents that the sidewalls 4-5 can move apart at the rearmost ends if the connection means 37 should not function as intended.

[0140] It is noted that the fitting parts 31 do not necessarily have to be situated laterally against the sidewalls 4-5, but can also be mounted underneath the sidewalls.

[0141] According to a variant, a guiding mechanism 38A is applied, with fitting parts 31-33 situated underneath the drawer, and wherein, for example, the fitting parts 33 are fixedly attached to the front wall 2 and the rear wall 3. In this manner, also an internal reinforcement is created in the drawer, which, in combination with the particular assembly, results in a drawer which can be assembled in a smooth manner and still clearly is stable.

[0142] FIG. 10 also illustrates the seventh aspect of the invention, as the sidewalls can be coupled to the front wall by means of an angling movement A from inside towards outside and this embodiment also shows the other characteristics of the seventh aspect.

[0143] FIG. 11 represents the use of a dowel 40 which is put through the respective sidewall 5. In practice, the whole will be realized such that the dowel 40 clamps into the rear wall. In the sidewall, it can or cannot be made clamping. In the case of a not-clamping cooperation between the dowel and the sidewall, a collar or head 41 will be provided. Thus, FIG. 11 is illustrative for a particular embodiment of the seventh aspect as well as for the eighth aspect.

[0144] It is noted that the aforementioned FIG. 8 is a self-explanatory example of the ninth aspect of the invention. In a still more preferred embodiment, the groove or groove profile 25A, on the left hand side as well as on the right, is directed with its deepest point outward. This latter offers the advantage that in the mounted condition, the bottom will also prevent that the sidewalls come loose from the front wall. As mentioned in the introduction, the inclined displacement preferably is made impossible at least by the remaining corner connections among the walls. This can be achieved, for example, by applying the corner connections represented in FIGS. 2, 4, 10 and 11, between rear wall and sidewalls. Such corner connections namely prevent a mutual removal of the distal ends of the sidewalls, there where the tongues of the ninth aspect are situated. The corner connections of FIG. 9 can be applied, too, however preferably in combination with a groove profile 25A which is directed with its lowest point outward, such that the bottom can also work against a possible inclined displacement of the tongue out of the groove.

[0145] In FIG. 12, schematically an example is represented of a device applying the method of the tenth aspect, in the case of a front wall or front panel. The device comprises a pass-through system with conveyor belts 42-43 which determine a feeding entry 44 and discharge 45. In a first processing station 46, the front walls 2 are provided with groove profiles 25, by means of milling cutters which preferably engage the front wall from the underside. In the processing station 47, bore holes 48 will be made from above, for example, for providing handles. In the processing station 49, by means of a saw 50 a groove 21 is provided in the downward-directed side, for attaching the bottom. Herein, the front wall moves along the rotating saw. Possibly, the saw may move up and down in a rotating manner when the groove does not have to be made completely continuous. Preferably, in the processing stations the working pieces will be kept stationary.

[0146] FIGS. 13 and 14 represent how a groove profile 25 can be realized with a milling cutter 51 by means of an entering movement B1 and a to-and-fro movement B2. Herein, FIG. 13 is a schematized view according to arrow F13 in FIG. 12.

[0147] FIG. 15 shows a variant in which an undoubling is applied by making use of two milling cutters 51, such that two smaller movements B2 can be applied which are performed simultaneously, by which time can be saved.

[0148] It is clear that with such milling cutter it is also possible to enter on the one side and exit on the other. Possibly, this movement B2 can extend over two walls which still are connected as a single panel, wherein this panel afterwards will be cut in two.

[0149] FIG. 16 shows a groove profile 25 obtained by means of a variant, wherein by means of a milling cutter 51 an ingoing movement B1 is made at a distance from the motion line B2 or the centerline 52 of the actual groove profile 25. In order to bridge over this distance D, preferably after a widened part 53 of the milling cutter 51 is already situated underneath the surface of the wall 2 to be milled, and still better after this milling cutter 51 has achieved its final depth, the milling cutter 51 performs a lateral movement B3, preferably in the plane of the wall 2. Thereafter, the movement B1 is performed, possibly to and fro, as already described above. It is self-evident that with the exiting movement preferably again the distance D is bridged over, in opposite direction from the initial motion line B3. Generally, the distance D preferably is smaller than the maximum radius R of the milling cutter 1. In this case, a distance D has been chosen which corresponds or approximately corresponds to the undercut to be performed. The outer contours of the obtained groove profile 25 are represented in dashed line 54.

[0150] The advantage of entering eccentrically or performing the ingoing movement B1 with the center of the milling cutter at a distance D from the centerline 52 of the groove profile 25 is that a higher-quality cut can be obtained. In particular, the quality of the cut portion 55 in the proximity of the point 56 is increased, where the ingoing movement B1 or the exiting movement of the milling cutter 51 is performed. In general, the improved cut portion 55 preferably is situated at the edge of the groove profile 25 with which the locking part 12 of the tongue 10 cooperates, and/or on the interior side of the composed element or the drawer 1. Improving the quality of the cut is of particular interest for cutting in laminated panels, such as in panels which are provided with a decorative layer of, for example, laminate, lacquer, melamine, PVC foil, veneer and the like. Improving the quality of the cut is also of interest for milling in panels consisting substantially of particle board, such as wood particle board.

[0151] Another advantage of entering eccentrically is that a connection can be obtained over a larger part of the groove profile. In fact, the cut portion 55 now can also provide for an undercut with which the locking part 12 of the tongue 10 can cooperate.

[0152] FIG. 17 represents an example, wherein the milling cutter 51 has entered on one side of the groove profile 25 and has exited it on the other side, and wherein on both sides an eccentric entering/exiting has been applied.

[0153] FIG. 18 represents another embodiment of an eccentric exiting and entering of the milling cutter 51, wherein the points 56 of entering and exiting can be found on opposite sides of the centerline 52.

[0154] It is clear that the technique of entering eccentrically can also be applied with groove profiles which are made finite on only one side of this profile, and wherein the other side of the groove profile coincides with a side of the element to be milled, or wherein the groove profile, in other words, is open at this side, similar to the alternative on FIG. 6 represented in dashed line.

[0155] Preferably, the eccentric entering is applied in combination with a method having the characteristics of the tenth aspect. According to a variant, it is not necessary that the basic panel is transported along a processing station by means of a pass-through system. Such eccentric entering can be performed by means of any device with at least one milling cutter.

[0156] Generally, the technique of entering eccentrically can be applied for realizing groove profiles 25, which are finite on one side or on two sides, in panel elements. These panel elements do not necessarily have to form the walls of a drawer 1, however, may also form part of a composed element, such as a cupboard, desk, table or the like.

[0157] FIG. 19 represents another tongue and groove connection, which can be applied within the scope of, for example, the ninth aspect of the invention, however, in general can be applied as a corner connection in any composed element. The particularity here is that the connection, in this case the tongue 10, is provided with a flexible material or with a flexible element 57. Such element 57 is provided in order to counteract any possible play in the tongue-groove-connection. In a coupled condition, the flexible element 57 presses tongue parts, in this case the tongue parts made in one piece with the panel or sidewall 4, against reference surfaces 58-59 of the groove profile 25, as a result of which an acceptable mutual positioning among the connected walls 2-4 can be achieved. Such connection can show less or no play in comparison to a traditional tongue-in-groove-connection.

[0158] Preferably, a first reference surface 58 of said reference surfaces 58-59 is formed internally in the groove profile 25. Preferably, a second reference surface 59 of said reference surfaces 58-59 is formed on the surface of the wall 2 with the groove profile 52. Such arrangement of the reference surfaces is illustrated by means of FIG. 19. It is clear that the reference surfaces 58-59 in general preferably extend transverse in mutual respect.

[0159] Said flexible element 57 can be manufactured, for example, of one or more synthetic materials, such as polyethylene, polyvinyl chloride, polypropylene and the like, for example, by means of an extrusion, coextrusion or injection molding technique.

[0160] Here, the flexible element is provided with a lip 61 which is rotatable around a hinge 61, said lip cooperating with the groove profile 25 for obtaining said pressing on. Of course, other mechanisms are not excluded. Preferably, a snap effect is applied, such as here, wherein during the coupling of the walls 2-4 a to-and-fro movement of the flexible element 57 or a part thereof is obtained. Use can also be made of elastic compression, followed by relaxation of a flexible material.

[0161] According to a variant, instead of a flexible element 57 also an element, whether or not rigid, can be used, which, for example like a wedge, is driven into an opening between the tongue and the groove, whether or not automatic, in order to obtain said pressing-on against the reference surfaces 58-59.

[0162] FIG. 19 represents in dashed line 62 that preferably a space 63 is applied between the surfaces of tongue and groove which do not form part of the reference surfaces 58-59.

[0163] Although the flexible element 57 or flexible material here is illustrated at the tongue 10, it is also possible that it is situated in the groove 11.

[0164] FIG. 20 schematically represents an example of a device 64 applying the method of the eleventh aspect.

[0165] FIG. 21 represents that for manufacturing drawers 1 according to the eleventh aspect, it will be started from a larger panel or board 23, from which at least two walls 3-4 are obtained. In this case, three walls 2-4-5 are obtained from the respective panel or board 23, namely two sidewalls 3-5 and a rear wall 4. The respective final walls 3-4-5 are situated in each other's prolongation in the larger panel or the board 23. In dashed line 24, the separation between the respective walls 3-4-5 is represented, such as it will be obtained after subdividing. In this case, the larger panel or the board 23 comprises a core material 65, such as a MDF or HDF panel or a panel of wood particle board, with a decorative layer 66-67 on both flat sides, such as, for example, a foil or a laminate. Of course, the invention of the eleventh aspect can also be applied with other types of panels, such as with solid wooden panels.

[0166] As FIGS. 20 and 22 show, by means of milling tools 68-69 profiles are formed allowing that the finally obtained walls will fit into each other in a locking manner. To this aim, use is made of a tongue 10 and groove 11 with locking parts 12-13, wherein these profiles can be joined together laterally and wherein the respective groove 11 is provided on the interior side of a first wall 3, namely, in this case on the interior side of the final rear wall 3, whereas the respective edge 10 is provided on the narrow end 19 of a second wall 4, namely in this case on one of the narrow ends 19 of both final sidewalls 4-5. For forming the tongue 10, the milling tools 68 engage on both short sides of the larger panel or the board 23; for forming the groove 11 or the groove profile 25, the milling tools 69, for example, such as here, can engage on one of the flat sides of the larger panel or the board 23.

[0167] For forming the tongue 10, use is made of a pass-through milling machine 70, wherein the larger panel or the board 23 is moved with its short edges over at least two and in this case three milling tools 68. It is known as such, for example, from WO 97/47834, to form locking profiles at the edge of a panel by means of at least two rotating milling tools. To this aim, preferably two rotating milling tools are applied, which are arranged at a different angle in respect to the panel.

[0168] For forming the groove 11 or the groove profile 25, the device 64 of FIG. 20, per groove 11 to be milled, comprises at least two additional rotating milling tools 69. In the example, these are arranged in the pass-through milling machine 70.

[0169] FIGS. 20 to 22 clearly show that said rear wall 3 and both sidewalls 4-5 are manufactured from one and the same board 23 and that herein the respective groove 11 and the respective tongue 10 are formed by means of a treatment, in this case consisting of a plurality of partial treatments, namely a plurality of milling treatments, performed on said larger panel or board 23. Only after this the respective panel 23 or the larger panel are subdivided into the respective walls 3-4-5 by means of a dividing device 71, such as a sawing device with one or more rotating saw blades 72.

[0170] FIG. 23 represents the obtained walls 3-4-5. FIG. 24 represents that, for example, the sidewalls 3-5 can also be post-treated for realizing connection means 9 other than locking profiles, or a portion of such connection means 9. In the example, to this aim also bores 17 are performed for providing dowels or other connection elements 15 therein. FIG. 25 represents that, for example, the rear wall 3 can be provided with an edge finishing, for example, such as here in the form of a glue-on masking strip 73 or ABS strip.

[0171] FIG. 26 represents the assembly or the drawer 1 which can be obtained on the basis of the respective sidewalls 4-5 and rear wall 3. To this aim, additionally a front panel or front wall 2 is attached to the narrow end faces 19 of the sidewalls 4-5, by means of the aforementioned dowels, and a drawer bottom 6 is inserted into grooves 21 provided for this purpose in the respective walls 2-3-4-5. Such grooves can be provided in the walls 2-3-4-5 in a similar manner as illustrated in FIG. 20. Such processing station 49 is not represented here, however, can be arranged downstream in the device of FIG. 20 in the same manner as illustrated in FIG. 12.

[0172] The embodiment represented in FIG. 26 also shows the characteristics of the first aspect mentioned in the introduction. It is clear that any locking profiles can be applied, which preferably can be inserted laterally. Thus, for example, possibly the gap 14 can be omitted from the tongues 10.

[0173] It is clear that the method as represented in FIGS. 20 to 24 also shows the characteristics of the tenth aspect mentioned in the introduction.

[0174] As aforementioned, it is clear that the invention is intended in particular for wood-based drawers.

[0175] The present invention is in no way limited to the embodiments described by way of example and represented in the figures; on the contrary, such drawers and methods for manufacturing drawers can be realized according to various variants without leaving the scope of the invention.
