In order to fit one such front element with panes (38, 44) of a desired type of design, whereby the limbs receiving said panes can be joined without any problem, the invention provides that said limbs are joined by means of at least two wooden elements (106, 108) which are permanently fixed in one frame limb and detachably fixed in the other.

Description

The present invention relates to a frontal furniture element according to the general concept of claim 1.

BACKGROUND OF THE INVENTION

ΡΟΕΡΟ 079 873 A1 is known one furniture front element with an outer frame with a mountable and replaceable inner frame and a mountable and replaceable infill. The arms of the outer and inner frame are bluntly aligned. The inner frame is loosely mounted in the outer frame so that the individual frame arms can be removed independently when the outer frame is closed. To do this, the joint on the outer frame arm must be uninterrupted.

EP 0 148 041 A1 discloses doors with transverse arms which are mounted between two vertically extending arms which are connected by a butt joint.

One furniture front element, particularly for kitchen and cabinet furniture, is described in FR-A 24 94 573, where worn or non-modern front doors are replaced with new ones. Only visible fronts are renewed for furniture remediation.

From PCT / EP 88/00138 (DE 38 05 944 A1) a furniture front element is known in which the frame arms are detachably connected to one another by means of clamping fittings. Due to the construction of the connecting elements, the frame arms must be of minimum dimensions. Apart from this, the frame consists of frame arms produced by cutting the profile bars with a right angle cut.

The frame arms are detachably connected to CH 658 777 A 5 by means of bolt joints, tongue-groove systems or plug-in resp. screw connections.

VDE 87 07 276 U1 discloses a door leaf in which its one longitudinal frame arm is connected to butt-mounted transverse arms via eccentric connecting fittings.

The corner connection between the butt-associated frame parts of the bed frame is realized according to DE 296 04 176 U1 with obliquely drilled wooden pins.

According to EP 0 810 377 A1, a screw connection is used to connect two profiles.

The bevelled frame arms are connected according to FR 2 466 219 by means of screw elements whose heads are accessible from the side edge of the arms.

DE-A-2 062 405 discloses a fastener for building boards of all kinds. The components are connected by chamfer. In this case, a borehole extends from the outside of one component, which is directed to the borehole of the other component to be joined. The metal mandrels are then inserted into the two mutually adjacent holes, which are screwed into the visible screws.

The present invention is based on the problem that the furniture front element, which is intended in particular as a door to kitchen or cabinet furniture, must be developed in such a way that the panels can be replaced without difficulty according to the desired arrangement, the support arms being connected seamlessly. At the same time, it must be ensured that the mutual rotation of the frame arm is avoided, which could result in the risk of possible breakage of the frame arm material such as e.g. wood. It should also be possible to dimension the frame arm almost without restrictions.

According to the invention, this object is achieved by the features of the characterizing part of claim 1.

By means of the measures according to the invention, it is possible to simply fold the frame arms and then connect them by means of predominantly screw elements, without the connecting elements having to penetrate in a small space the frame arms from the rear. Consequently, the advantage is that the wooden elements such as the wooden buckles or the wooden buckles. the wooden round bars can be next to each other. Thereby, the frame arms can be small in size, without the disadvantages with regard to the replacement of the infill or the restoration. inner frames.

The connecting element is preferably a countersunk head screw such as e.g. cross, from where the axial hole emerges to accommodate the cap. The corresponding screws are also known as spax screws (self-tapping screws).

The wood clip itself preferably has a length of about 1/3 to 2/3, preferably 1/2 of the length of the round wooden bar.

The wooden clip should be at the outer edge of the frame and the circular wooden bar at the inner edge of the frame. Thus, at these lengths, there is sufficient space for the wooden clips.

According to a further feature of the invention, it is envisaged that the bore holes extending into each other are preferably arranged in parallel planes with respect to their longitudinal axes, so that they are interchangeable with one another, thereby securing them against extra turning.

Preferably, the wooden round bars in the longitudinal frame arm and the wooden clips in the transverse frame arm are screwed together. Furthermore, the holes should be drilled parallel to the cross-arms, which makes it easy to mount the frame arms or the frame arms. their release.

Apart from the connecting type of the frame arms, it is considered to each other that the visible inner or outer surface of the filler arms and / or the inner frame into which the filler is mounted forms part of the outer surface of the furniture front element. In this case, the visible inner and outer surfaces of the inner frame can be differently profiled and / or with different layers on the surface. Furthermore, it is preferable that at least the profile material is wrapped with a plastic sheet, the plastic sheet projecting in the region of the tongue bottom.

The method of manufacturing a furniture face element with a frame and a replaceable panel preferably comprises the following steps:

manufacturing the first and second frame arms as longitudinal and transverse arms by cutting the profile rails in a right bevel, drilling the first and second holes to be parallel to the longitudinal axis of each frame arm at prescribed standard distances to the frame arm reference surface, inserting and sealing the first cylindrical a wooden element into the first bore of each inclined surface of the frame arm to be the longitudinal frame arm, wherein the first wooden element overhangs the inclined surface, inserting and gluing a second cylindrical wood element into the second bore of the frame arm to serve as a cross frame joining the two transverse frame arms to the longitudinal frame arm by inserting the first and second wooden elements into the respective free second and first drilled holes of the bounding arm, screwing the non-glued parts of the wooden elements out of z the side of the frame arms, inserting a filler or filler which is inserted into the inner frame into a U-shaped folded frame arms, joining another longitudinal frame with the transverse frame arms by inserting the protruding parts into the first and second wooden elements into the respective free first and second bores holes of bounding frame arms and unscrewing of non-glued parts of wooden elements from the rear side of the frame arm.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1-3, a first embodiment of a composite front furniture element 10 is shown, which is shown in FIG. 1 is folded and according to FIG. 2 and 3 can be disassembled in simple steps to change its exterior finish. The front furniture element 10 consists essentially of transverse frame arms 12,14 and longitudinal frame arms 16,18 in which the padding 20 is placed. The arms 12, 14, 16, 18 are connected releasably by cylindrical wooden elements in the form of wooden clips 22, 24 and 24. In particular, reference is made to the explanation of FIG. 13-15, by which the essential features of the invention are clear.

The various assembly states of the front furniture element 10 according to the invention are shown in FIG. 1-3 to make it clearer that the front furniture element can change its exterior appearance in a few easy to implement steps. If in FIG. 1 shows a folded front furniture element 10 which can be connected, for example, to the housing body by means of hinges 30, 32, then in FIG. 2, the outer longitudinal frame arm 22 is already disengaged from the transverse frame arms 12, 14 in order to remove the replaceable and reversible filler 20 (FIG. 3) and to rotate or rotate it respectively. replace with another fill.

In FIG. 4 - 7, the front furniture element 34 is shown, being used as shown in FIG. 1-3 for the same elements of the same reference numerals. In other words, the front furniture element 34 consists of transverse frame arms 12,14 and longitudinal frame arms 16,18 which are detachably connected to each other by means of wooden clips 22, 24 and wooden circular bars 26, 28. The inner longitudinal frame arm 16 also has hinges 30, 32 or corresponding suitable fasteners to connect the door 34 to the furniture body.

In contrast to the embodiment of FIG. 1-3, the filler 20 is not directly inserted into the outer frame, which forms the arms 12, 14, 16, 18, but only through the inner frame 36, which consists of the inner frame arms 38, 40, 42, 44.

In FIG. 4 to 7 show different mounting states of the front furniture element 34 to make it clear that the front furniture element 34 can be changed in a few steps. 4, the front furniture element 34 is shown from the rear. In FIG. 5, the longitudinal frame arm 18 is released and removed from the transverse frame arms 12, 14, in which the inner longitudinal arm 44 is detachably positioned to rotate the panel 20, respectively. replace with another.

If, in addition, rotating the inner frame 36, it is only necessary to remove the arms 38, 40, 42, 44 from the outer frame groove, which consists of individual grooves of the frame parts of the outer frame, as shown in principle in FIG. 7th

In FIG. 8 is a cross-sectional view along line VIII-VIII of FIG. 4, in an enlarged view, to describe in greater detail the outer frame which is formed by the arms 12, 11, 16, 18, and the inner frame 36 which can be detachably mounted therein and which comprises the arms 38, 40, 42, 44. Each arm 12, 14, 16, 18 and thus the arms 16, 18 of FIG. 8 are part of the profile rails which are sold on a conventional meter and are provided with a groove 46, 48 in their longitudinal direction. The legs 12, 14, 16, 18 are arranged relative to the groove 46, 48 so as to form a continuous internal groove. into which they can be detachably mounted according to the embodiment of FIG. 1-3 of the filler 20 and according to the embodiment of FIG. 4-7 the arms 38, 40, 42, 44 of the inner frame 36. For this purpose, the inner arms - in FIG. 8 arms 40, 44 - one portion 50, 52 which is adapted to the groove 46, 48, so that the arms 40, 46 can preferably be precisely fitted into the grooves 46, 48.

The inner arms 38, 40, 46, 48 are also cut from profile rails which are sold on a conventional meter and also have a continuous internal groove, which is formed of grooves 54, 56 into which the filler 20 can be detachably fitted. The filler in the embodiment of FIG. 8 out of a total of three plates 58, 60, 62.

FIG. 8, it can further be seen that the grooves 46, 48 of the outer frame are in a different plane from the grooves 54, 56 of the inner frame 36, which results in a cassette effect and with it the associated depth effect of the front element 34.

The details of the inner frame 36, in particular with respect to the shaping of the inner arms 38, 40, 42, 44 to be detachably fitted to the outer frame, are apparent from FIG.

Since the arms 12, 14, 16, 18 have the same profile, the characteristic features of the frontal furniture element or the frontal element are explained. of the inner frame 36, which is inserted into the outer frame, on the basis of the longitudinal frame arm 18.

The groove 46 is fitted with a portion 52 of the inner arm 44, and the area that faces the bottom surface 64 of the groove 46 is designed as a concave curvature 66. This has the advantage that unevenness in the region of the bottom 64 does not cause the inner arm 44 to creep.

Further, the arm 44 is designed as a so-called " the pivoting arm, i. both the outer surface 68 and the inner surface 70 (shown in dotted lines) can be used as desired as the visible outer surface of the front furniture element 34, each surface 68, 70 having a different color and / or surface.

Therefore, in order to achieve a different treatment, it is only necessary for the inner arm 44 to be removed from the groove 46 and rotated 180 °. In this case, the arm 44 may have two grooves 72, 74 which are parallel to each other and at a distance relative to each other, into which the infill 20 can be inserted, always in a groove which is facing the outside of the face, so in this embodiment into the groove 72.

The concave curvature 66 of the arm 44 is particularly advantageous when there are unevenness in the region of the bottom 64 of the arm 18. These can, as can be seen from FIG. 10 - formed when the arm 18, e.g. MDF, covered with a plastic film 76, whereby the ends overlap in the bottom region 64. The overlapped region is indicated by the reference numeral 78. Now that the inner arm 46 of FIG. 9 into the groove 46, the overlapped area 78 cannot cause problems since this area is located in the area of the concave curvature 66.

In FIG. 11 shows a special modification of the outer frame arm 80 which is completely encased in the plastic film. In order for the inner space of the groove 82, which is intended for the inner arm (not shown here), to be fully expanded, the groove depths in the region of the side walls 84, 86 are distinguished from each other so that the coated surface on which the adhesive is applied is inserted. 82 does not touch the opposing walls 84, 86. Due to the corresponding modification of the outer arm 80, the possibility of completely covering the material with foil without simple restraint, from the front side view of the front furniture element, is possible by simple constructional modifications. This is accomplished by the side wall 86. If the grooves were not deeper at different locations and the arm 80 would be fully extended at the same time, then the depth of the groove to the width of the groove bottom should be chosen such that the bottom is twice as large as the original bottom.

In FIG. 12 shows another example of an embodiment of a frontal furniture element according to the present invention in which the filler is inserted directly into the outer frame, that is to say into the arms 12,14,16,18. In the embodiment of FIG. 12, the filler consists of three elements 88,90, 92, the elements 80,92 having the shape of a plate and the element 90 having a part that projects outwardly to produce a cassette effect.

Referring to FIG. 13-15, in order to illustrate the inventive idea, it is purely principally illustrated how the frame arms 12 should be coupled together - in the exemplary embodiment of the arms 12 and 18 - while at the same time guaranteeing the detachability of the cross frame arms 12 at least with respect to the longitudinal arms of the outer frame 18; 14th If, according to FIG. 13, the inner frame is inserted into the outer frame, so that the arms of the inner frame 38, 44, the inventive idea of course also extends to frontal furniture elements in which the panel is immediately fitted into the outer frame.

Due to the connection of the frame arms 12, 18, bores 98, 100 and 100 respectively bore out from each chamfered surface 94, 96. 102, 104, which interconnect at the folded arms 12, 18. Thus, hollow spaces are formed parallel to each other, which consist of boreholes 98, 102, respectively. 100 and 104. Cylindrical wooden elements in the form of wooden clips 106 and 104 are inserted into the boreholes 98, 100, 102, 104. of wooden round bars 108 which guarantee the desired anti-twist connection between the frame arms 12, 18, while at the same time providing removability. In this case, one part of each wooden element 106, 108 is glued into one of the boreholes, and that part of the wooden element 106,108 that projects over the respective tapered surface 94, 96 is screwed in the other borehole from the rear side of the arm 12, 18. the wooden clip 106 is threaded into the bore hole 102 and the portion that projects into the hole 98 is screwed to the arm 12. Conversely, the circular wooden bar 108 is threaded into the hole 100 of the transverse frame arm 12 and the hole 104 overhanging is screwed to the longitudinal frame arm 18 .

FIG. 13 further shows that the wood clamp 106 is shorter than the wood annular bar 108. The shorter wood clamp 106 is disposed relative to the transverse arm 12 towards the outer edge and the wood annular bar 108 extends more towards the inner side of the arm 12.

The boreholes 98, 100, 102, 104 can be positioned with respect to their longitudinal axes in a plane parallel to the front face of the front furniture element, as shown in FIG. 14. Alternatively, it is possible to arrange the drilled holes 98, 102 in a plane other than the holes 100, 104, as is purely principally shown in FIG. 15th

Since one of the cylindrical timber elements 106, 108 protrudes from each tapered surface 94, 96 before folding the arm 12, 18, it is possible to fold the arms 12,18 easily while subsequently screwing the wooden elements 106, 108 from the rear sides of the arms 12, 18. For this purpose, it is preferable to use self-tapping screws (Spax screws) 105 which are covered externally by covers 107.

Referring to FIG. 16 is a schematic diagram illustrating how the arms of the inner and outer frame are made in a right oblique section to fit exactly. Thus, the profile rail 106 ', which forms the outer leg, is easily connected first with the profile rail 108', which forms the inner leg, in the region HO, which is later discarded as waste. This connection can be realized, for example, by means of staples or by shooting, etc. Thus, it is ensured that the profile bars 106 'and 108' do not move relative to each other when sawing with the saw blade 112. After the saw blade has been beveled, the cut surface 114 is applied to the stop 116, which determines the length of the not-specified arm. Since the saw blade 112 has an unambiguous association with the stop 116 and the first cut 114 is also unambiguously aligned with the saw blades 112, it is still ensured for the slant of the right angle that, according to the principal representation in FIG. 16, the cut arms have the desired length, while the interlocking of the profile rails 106 'and 108' ensures that when folding the inner and outer arms there is a precision which ensures accurate slanting in the folded front furniture element. Since normally more rails are cut from profile rails that are available on standard meters and always end up as waste, a simple joint in this area is possible without any disadvantages when cutting the rails.
