Abstract

Frontal element for furniture, such as a door, comprising an outer and inner frame, into which may be fitted an interchangeable panel (32, 73, 74, 76). The struts which form the frame (14, 18, 24, 28) are fully mitred and, fundamentally, held together simply by the securing elements which connect, without the help of screws, the outer struts of the frame (14, 18). In order to achieve a pleasing appearance, the grooves in the outer and inner frame (62, 64, 70, 72) which take the inner frame or panel (32, 73, 74, 76) are disposed in planes at a distance from each other.

Description

DK 163273 B

The invention relates to a furniture front element with an outer frame and one in this insertable and interchangeable inner frame and one in this insertable and interchangeable filling, where the outer frame consists of cut pieces of profile moldings with a groove extending in the longitudinal direction.

Such a door is known from EP-A-0 079 873. The frame pieces forming sides of the outer and inner frame collide bluntly. The inner frame is arranged so loosely in the outer frame that the individual frame pieces can be independently removed from the closed outer frame 10. For this, one of the outer frame frames must have a continuous slot. EP-A-0 148 041 discloses a door with two transverse frame sections extending between two vertical frame pieces, which are joined by blunt butt joints. Fills or inner frames that can easily be replaced do not exist. A furniture front element, especially for kitchen and cabinet furniture is described in FR-A-24 94 573, where worn or outdated front doors can be replaced with new ones. The furniture front elements are thus intended for the renovation of furniture, where only the visible front parts must be renewed. By the 20 interchangeable arrangement of the fillings, it is thus possible to change the appearance. For this purpose, each filling is preferably composed of two opposite plates, which together have four sides of decoration.

As the frame pieces are cut off by moldings that are available in fabric, a furniture front element of the desired size can be manufactured without much expense. The profile list preferably consists of a core of MDF, which is wrapped in plastic.

SUMMARY OF THE INVENTION It is an object of the present invention to further develop a furniture element of the kind in question intended for the cleaning of furniture, especially kitchen and cabinet furniture, so that it is possible by simple means to make a "transformation" by the parts forming the furniture front element. For this purpose, in view of the quality of the final product, the manufacture must be capable of being described as industrial, although it must also be possible to carry out a problem-free individual

DK 163273 B

2 adaptation to different sizes and or desired decoration effects. Replacement or rebuilding of individual elements and their interconnection must be possible without problems, and especially without the need for different design of the individual 5 parts.

This is mainly achieved by the fact that the frame pieces in the outer and inner frame everywhere form a genuine ring and can be fixed with the forces produced in the outer frame frames connecting elements and that the circumferential inner groove in the outer frame extends in a plane which is offset relative to the plane in which the inner note of the inner frame extends.

In the construction according to the invention, the exterior of a known front element 15 for cleaning furniture can be "transformed" by simple means, so that in addition to replacing the filling to produce various decorative effects, a replacement of the inner frame loosely inserted in the outer frame can also be performed. without requiring different designs of the individual frame pieces after 20 "loose" placement of the inner frame with filling, which could possibly result in an undesirable and noise-causing movement of the parts.

As the notes proceed in different levels, it is possible that the furniture front element can be manufactured in cassette form, ie. that the filling is staggered forward in relation to the outer frame. This gives the added advantage that the front element appears to have a larger cross section, making it appear heavier and more "weighty".

In one embodiment of the invention, the 30 visible inner or outer surfaces of the inner frame frame pieces of choice are part of the furniture front element's outer front. The inner and outer surfaces of the inner frame can thereby be differentiated and / or have different colors. This multiplies the number of options for changing the exterior of the furniture front member 35 compared to the number of options of known furniture front members for remediation purposes. Without renewal of front 3

DK 163273 B

the parts of the element or of the whole as a whole, therefore, a mixed change and adaptation can be made to the colors which appear, respectively, with the change in taste over time.

In order to allow trouble-free replacement of the filling 5 and / or the inner frame frames, it is proposed that the cut pieces forming the inner frame frames are substantially joined together by the forces caused by the connecting elements in the outer frame frames in real slight. Of course, independently of this, for fixing the position 10, a connection of the interposed frame pieces, e.g. using nails or pins. Nevertheless, the guide and retaining are essentially done by means of the outer frame. This means that only one of the outer frame frames has to be removed with the loosely arranged frame piece 15 of the inner frame from the furniture front element to change the filling and / or the inner frame.

In order to obtain a "stress-free" support of the inner frame frames in the circumferential groove of the outer frame, it is proposed that the portions of the 20 inner frame frames located in the inner groove in the outer frame abut the abutment of the inner groove. Further, the portion facing the bottom surface may be formed as a hollow, the edges of which abut against the bottom surface. Hereby, the advantage is obtained that unevenness in the area of the bottom surface, especially in the middle, does not cause visible irregularities in the insertion of the inner frame frame pieces into the outer frame, since at least the area at the inner groove walls, which supports the groove portion of the inner frame frame, is supported. designed plant.

The groove depth in the outer frame and / or the inner frame in the area 30 at their innermost restriction wall can be made smaller than in the area at the outer wall. Hereby, the advantage is obtained that, when using a coated profile material, the inner groove can be easily coated, since in one embodiment there may be an overlap of the coating material in the groove bottom. This ensures that the entire frame piece is tightly encased in cladding material to the cutting surfaces,

DK 163273 B

4 so that especially in the use of the furniture front element according to the invention in damp rooms, e.g. In kitchens, moisture cannot penetrate between the core of the frame side pieces and the cladding.

If one wishes to choose the groove depth uniformly over the entire groove bottom without giving up the overlap of the cladding material in the area of the groove bottom, in one embodiment the width of the groove bottom may be twice as large as the groove depth. The width is preferably 13 mm and the depth 6 mm.

The invention also relates to a method for producing a furniture front element with frames and interchangeable filling of the present invention, which method is characteristic of the following working steps: a) inserting a cut piece of a first profile molding with a longitudinal extension (b) establishing a releasable shear-resistant connection between the first and second profile lists; (c) producing (a first and second set of) frame pages by cutting the associated profile moldings. (d) aligning and / or fitting devices in the second set of moldings to their later, at least partially releasable connection; e) aligning and assembling an upper and lower frame piece and a first side frame piece of the second set (f) introduction of several plate-shaped, differently decorated elements consisting of fillings g) in the groove of the assembled first set of frame pieces; g) assembly of the side pieces formed as a unit of a frame piece in the first set and a frame piece in the second set with the upper and lower frame pieces above connecting elements.

35 A further design of the method is peculiar to, 5

DK 163273 B

h) detaching the cut pieces of the first profile list from the cut pieces of the second profile list before aligning and / or fitting the devices into the second set of profile lists; (i) producing the first, longitudinal direction of the second profile list formed; (second set) frame bores extending bores starting from the cutter faces of the profiles, the front face of the second set of moldings serving as a standard for the bores, 10 k) producing two more bores starting from the back of the second set of frame pieces, l) the two additional bores longitudinally cutting the first bores extending in the longitudinal direction, and m) the first 15 frame pieces formed by the first profile moldings are then inserted into the groove associated with the cutting in the second set of frame pieces.

The connection of the profile strips indicated in working step b) can be made in an end region, so that the connection produced preferably by staples cannot be in the way of shortening. In addition, by "one-sided" determination, the advantage is that the profile molding is constantly connected, but can still be taken apart after cutting, if the cutting occurs from the non-connected end.

Furthermore, it should be noted that the working steps i) and k) can of course also be carried out in reverse order. Furthermore, only one bore may be produced if a sufficient comparison of the frame pieces over the connecting elements to be introduced into the bores which are flush to each other should already be achieved.

Finally, it is noted that the overall frame can be closed immediately prior to insertion of the filling to connect the inner frame pieces with the outer frame pieces e.g. with staple stitch. In this way, the frame pieces are not inadvertently twisted when replacing the filling.

In the method according to the invention,

DK 163273 B

The 6 element is manufactured in an industrial way, with adaptation to individual wishes without any problems. By aligning the frame pieces on the front surface as a standard surface, it is ensured that the visible surfaces of the frame pieces are evenly flush and that the frames themselves in the mud completely collide without forming any holes. As the inner frame frames are finished cut together with the outer frame frames it is achieved that the inner frame is also composed with exact fit, whereby extra connection elements between the individual frame pieces are not necessary, since the frame is held together by the connecting elements connecting the outer frame frames.

As mentioned, the profile moldings releasably interconnected at the intersection are preferably bonded together in the area not used for the furniture front member, so that the connection does not have to be terminated by special aids, e.g. tool.

To ensure that moisture cannot penetrate the frame pieces at the cut surfaces, these are sealed e.g.

20 using a glue. Finally, one end piece of each angular devil may be inserted into a slot extending parallel to the frame plane in the housing of the eccentric angle bracket and, when turning the housing, be retracted therein, and the portion of the angular devil contained in the slit is flattened so that the devil 25 is slidable in the slot. This creates the frame pieces without any problems in relation to each other. By tightening the eccentric angle brackets, the first frame pieces forming the inner frame can thereby align themselves with their outer surfaces smoothly and bump without 30 holes or spaces.

The invention is explained in more detail below in connection with the preferred embodiments shown in the drawing.

FIG. 3 furniture front element of FIG. 1 while removing the filling; FIG. 4 furniture front element of FIG. 1 while removing the inner frame; FIG. 5 is a section along the line V-V in FIG. 1, FIG. 6 is a detailed view of a frame piece inserted into an outer frame for an inner frame; FIG. 7 is a sectional view of a frame piece for an outer frame, cut in section; FIG. 8 is a section through another embodiment of a frame piece for the outer frame; FIG. Fig. 9 is an enlarged view showing the connection between the outer frame frames over an eccentric connection bracket; 10 is an angular devil in FIG. 9 is a side view from the front, and FIG. 11 is a view illustrating the principle of making the rarom pieces for the furniture front element of FIG. First

In FIG. 1-4 is a composite furniture front member 10, the member of FIG. 1 is fully assembled and in FIG. 2-4 shows how the furniture front element can be separated by simple handles to change its appearance. The furniture front element 10 consists essentially of an outer frame 20 composed of frame pieces 12, 14, 16, 18, and an inner frame 30 composed of frame pieces 22, 24, 26, 28 in which a loading 32 is loosely arranged. The outer frame pieces 12, 14, 16, 18 are, as further described in connection with FIG. 9 and 10, connected to each other over eccentric connecting brackets, whereby the inner frame pieces 22, 24, 26, 28, releasably arranged in the outer frame pieces 12, 14, 16, 18, are simultaneously retained.

To connect the outer frame pieces 12, 14, 16, 18 to each other without screw connections, housings 34 and 36 which cooperate with angular devils 38 are arranged in holes not designated 35. Each housing 34, 36 has a parallel to

DK 163273 B

8, a slit extending in the plane of the plane in which portions of the angular devil 38 can be placed. When turning the housing 34 or 36, the angular devil is pulled towards the housing. It can be seen that this occurs by the slot being disposed in a housing wall 44 and 5 46, respectively, which extend eccentrically relative to the pivot point of the housing 34 and 36. As the angle devil 38 engages behind the inside of the wall 44 and 46, respectively, with its end piece 48 and 50 respectively. when turning the housings 34 and 36, it will automatically be pulled in the direction towards the pivot points of the housings.

Hereby a secure connection can be provided between the frame pieces 12 and 14, 14 and 16, 16 and 18 and 18 and 12.

Furthermore, since the portions 40 and 42 which engage the slots in the walls 44 and 46 are flattened, the angular devil 38 has no possibility of turning the longitudinal axes of the legs.

Hereby, the frame pieces 12, 14, 16, 18 are aligned and their front faces are moved in a common plane towards each other and locked together. By means of the forces produced by the eccentric connection fittings, the inner frame pieces 22, 24, 26, 20 28 loosely arranged in the outer frame pieces 12, 14, 16, 18 are simultaneously aligned with each other and retained without the need for additional connecting elements.

In FIG. 2-4, various phases are shown during the assembly of the furniture front member to clarify that it is possible to change the appearance of the furniture front member 10 with handles which can be easily performed. FIG. 1 shows the back of the composite furniture front element 10, such as e.g. with a top hinge 52 and a bottom hinge 54 may be connected to a cabinet, FIG. 2 shows a stage where the outer frame piece 18 with the loosely arranged inner frame piece 28 is detached from the frame 30, so that the reversible or interchangeable filling 32 can be removed, as indicated in FIG. Third

In order to be able to further replace or reverse the inner frame pieces, these need only be loosened from the outer frame pieces 12, 14, 16, 18, as indicated by the inner frame piece 22 in FIG. 4. In this "dismantling", the furniture front element 10 is still connected to the cabinet above 9

DK 163273 B

hinges 52 and 54, the remaining outer frame pieces 12, 14 and 16 having a supporting function. After the inner frame pieces 22, 24, 26, 28 are completely removed from the outer frame pieces 12, 14, 16, 18, they can either be flipped and inserted again, or other inner frame pieces can be placed in the outer frame pieces 12, 14, 16, 18, before the filling 32 is inserted with an outward facing side having a different decorative effect. Thereafter, the frame piece 18 is joined together with the inner frame piece 28 with the outer frame pieces 12 and 16 by means of those shown in FIG. 9 and 10 show eccentric connection fittings. Finally, the individual frame pieces can be secured with plastic angular devils 56 inserted into the bores 58 and 60 of the outer frame pieces 12, 14, 16, 18.

FIG. 5 shows a section along the line V-V in FIG. 1 in 15 enlarged scale for further explanation of the details of the outer frame 20 formed by the frame pieces 12, 14, 16, 18 and the inner frame 30 formed by the inner frame pieces 22, 24, 26 and 28 which can be removably inserted into the outer frame. Each frame piece 14, 18 forms a piece of a profile list, which 20 appears as a meter product and which has a longitudinal groove 62 and 64 respectively. The frame pieces 12, 14, 16, 18 are arranged in relation to the grooves 62 and 64 so that is formed a circular inner groove into which the frame pieces 22, 24, 26, 28 can be interchangeably inserted. To this end, the inner frame pieces - in FIG. 5, the frames 24 and 28 - each a portion 66 and 68 adapted to the groove 62 and 64, respectively, to which the elements are connected, preferably by fitting. The inner frame pieces 24 and 28 are also cut off by moldings which are available as fabric goods, and also have 30 grooves 70 and 72 forming a circumferential inner groove in which the filling 32 is interchangeably arranged. In the embodiment of FIG. 5, the filling 32 consists of a total of three plates 73, 74 and 76, each having different decorations on the two sides.

In FIG. 5 it is seen that the grooves 62 and 64 which form in the circumferential inner groove of the outer frame 20 extend in a different plane than the circumferential inner groove of the inner frame 30, whereby

DK 163273 B

10, there is obtained a cassette effect and the associated depth effect in the furniture front element 10.

In FIG. 6, details of the design of the inner frame removably inserted in the outer frame are shown. The outer frames of the outer frame have a profile similar to that of FIG.

5 so that it is designated by the same reference numeral 18. In the groove 62 there is placed a portion 78 of an inner frame piece 80, in which the side facing the bottom surface 82 of the groove 62 is formed as a hollow 84. This gives the advantage 10, unevenness in the bottom 82 does not cause the edge position of the inner frame piece 80.

Furthermore, the frame piece 80 is formed as a so-called "turning frame", ie. that both the exterior 86 and the interior 88 can be used as a visible exterior on a furniture front element (shown in dotted lines) of choice, where the sides 86 and 88 may have different colors and / or be profiled differently. For this, it is merely required that the inner frame piece 80 be removed from the groove 62 and rotated 180 °. In order to also obtain a cassette effect in this case, there are two notes 90 and 92 in the inner frame piece 20 20, each offset relative to the portion 78.

The configuration with a hollow 84 in the frame piece 80 is particularly important when, as mentioned, there are irregularities in the groove bottom 82 in the frame piece 18. As shown in FIG. 7, the frame piece 18, 25 which e.g. may be made of MDF material, wrapped in a plastic foil 94, the ends of which overlap each other at the bottom 82, the overlap area being designated 96. If now placed in FIG. 6 in the groove 62, the overlap area 96 cannot be in the way as it lies 30 in the free space formed by the hollow 84.

In FIG. 8 shows a special embodiment of an outer frame piece 98, which is completely encased in a plastic film not shown. In order that the interior space of the groove 100 for not showing an inner frame piece can also be fully lined, the groove depth at the two side walls 102 and 104 of the groove is different, so that the glue 11

DK 163273 B

coating material after insertion into the groove 100 cannot come into contact with the abutting restriction walls 102 and 104. By a similar design of the outer frame member 18, with constructively simple changes 5, it is possible to completely cover the material with a foil without it not The filling 32 shown is controlled smaller, as seen from the front of the furniture element. This ensures the height of the wall 104. If one wishes to waive the different groove depth and at the same time have complete casing of the frame piece 98, then the groove depth 10 must be chosen in relation to the width of the groove bottom so that the width is twice the depth.

In FIG. 11 is schematically indicated how the frame pieces in the inner and outer frame can be manufactured with accurate fit in true miter cuts. First, a profile list 15 106, forming the outer frame piece, is joined with a profile list 108 forming the inner frame piece in a sub-section 10 which later goes to waste. The joining can, for example. happen by staples, jointing or similar. This ensures that the profile molds 106 and 108 cannot be displaced relative to each other during cutting with a saw blade 112. After the saw blade 112 is made with a miter cut, the cut surface 114 is laid against an abutment 116 which determines the length of an unspecified frame to be cut. Since the saw blade 112 has an unambiguous adjustment with respect to the stop 116, 25 and also the first cut 114 is unambiguously fixed with respect to the saw blade 110 to produce a true miter cut, there is always certainty that, according to the principle sketch of FIG. 11 molded frame pieces have the desired length, and when the profile moldings 106 and 108 are joined together 30 are obtained in the composition of the inner and outer frame pieces with an accuracy which guarantees a miter assembly with precise fit in a composite furniture front element. As several frame pieces are usually cut off from the molding, which is available as a fabric product, and an end piece is always eliminated as waste, the bonding on this piece can be done without any disadvantages of the finished cutting of the frame pieces.
