Description

The invention relates to a fastening device for plinth panels or similar cladding profiles for cabinet furniture, for example for Kitchen cabinet furniture.

Plinth covers for kitchen furniture in particular become conventional in most cases still on the front edges of the side cheeks of e.g. Kitchen base cabinets covered nailed with what however, this is particularly necessary for uneven floors Height compensation or a necessary height adjustment is difficult to accomplish. Likewise is it is generally inexperienced for such work Such users find it very difficult to use kitchen sockets to remove, for example, under the Dirt particles or kitchen furniture for example moisture in the event of leaks to eliminate at water connections and the like.

DE-U-78 04 923 is a fastening device with a height-adjustable support leg for cabinet furniture with separate Known plinth, in which the plinth detachable and adjustable in height to attach to the support leg is. This is especially meant to serve the previously Compensate for unevenness in floors as described and also for removing dirt or the like To mount the base panel detachably fastened. The Support foot on a retaining bar that extends over the entire The height of the support leg extends. This holding bar has an undercut cross section and is preferred dovetail or trapezoidal. A plinth holder is attached to this retaining strip fasten, which has locking lugs that the undercut Can reach approaches of the retaining bar. These locking lugs can on the Undercuts slide along and are in the pull-off direction locked in a way by the locking lugs. Thus, the plinth panel on each support leg can be held at variable heights. If necessary Height adjustment is, however, the base panel not fixed by the plinth bracket support, but may need additional means relined or otherwise attached to what overall to an appearance that is unsightly from the outside lead and e.g. when cleaning the kitchen floor can lead to the plinth panel falling off. In particular it is necessary to match the base cover to Support leg firmly with part of the plinth holder equip and the mutually movable parts behind to plug the base panel into one another.

DE-C-28 49 274 is a fastener known for plinth panels, the U-shaped one Bracket formed and on the top edge of the socle cover is attachable. This U-shaped bracket has side tabs or legs, each of which one after moving the U-shaped bracket into one Adapter piece or an adapter shape recess such can intervene that the base panel towards the front is secured against falling out. Should the plinth removed, the U-shaped bracket is again to move on the plinth so that the Locked position is released.

In a brochure "Franko furniture fittings" from Franke GmbH + Co. KG, metal and plastic processing, D-Balingen (12/92) is presented an aperture clip, designed according to the aforementioned DE-C-28 49 274 is and therefore also to be moved on the base panel is. There is also a fitting as Handle molded onto the U-shaped bracket. The side tabs or legs are parallel with one Provide locking profiles aligned with the direction of displacement. The corresponding locking counter profiling is on the provided on the kitchen furniture holder part. After moving the aperture clip is a Leg with its profile in the corresponding Bracket provided with counter-profiling bring. This mounting part is therefore in the assembly position attacked. The grid can be used to apply pressure from above to the panel using a screwdriver. This pressure from above causes the screen to be clamped against the floor, the rastering of a resetting movement opposing resistance in the sense of a resetting inhibition.

However, a complete blockage or position fixation in this assembly position cannot be achieved by the grid, since the base panel holder can be pushed out of the adapter mold recess in the longitudinal direction of the base panel, so that it can also be inadvertently returned to an unlocking position that releases the base panel.

One of the aforementioned fasteners Similar fastening device is also one Slide clip for holding a base panel. from the company Rehau AG & Co., D-95111 Rehau realized the also one-sided with one of the molded-on side Tabs or legs in a mold recess Can connect adapter piece. This slide clip has one Profiling, which is formed on the side in front of the tab and with which also a flutter of the sliding clip in its assembly position should be prevented. This sliding clip is in its installation position against unintentional shifting and therefore reset in a plinth releasing position also not secured. Also With this sliding clip it is therefore necessary to use the base cover Align horizontally and in case of uneven floors to reline.

From DE-U-85 32 013.7 and DE-U-86 00 238 are also fastening devices for plinth panels known, which in turn is on the front edge arrange the base panel and have it moved. Around the panel holder against unintentional shifting To have secured is with the DE-U 86 00 238 provided, vertically aligned locking profiles to provide. They also have from the known writings known plinth holder each formed leg, which are in the assembled Support the condition on the base plate of the furniture, a certain amount of force from above onto the plinth exercise. However, are uneven floors balance with the consequence of a larger one Distance between the top edge of the base panel and the underside of the base plate of the kitchen furniture the spring force is either very low or no longer at all. In this case it is To adjust the plinth panel and turn it reline to any force from above on the To have a plinth cover.

It is an object of the present invention to Fastening device for plinth panels of the entrance with the plinth panels Height-adjustable in an extremely simple manner on site are to be mounted safely and securely in such a way that Uneven floors without the need for more complex Allow adjustment work of the base panel to be compensated.

To solve this problem, the fastening device stands out of the type mentioned at the beginning by the features specified in claim 1.

In the fastening device according to the invention is a plinth or the like. Cladding profile with only in just a few simple steps only the base panel holder set, namely even at different altitudes and therefore at uneven floors, because after pressing down the hold-down device this due to the reset inhibition a movement against the hold-down or Clamping direction and other movements is prevented. Without other relining the fitter can do it on site without time-consuming adjustment work a necessary height compensation make. In a preferred manner, the adapter piece already used by the kitchen furniture manufacturer be, so that only the Use plinth holder and according to arrangement the plinth is to be pressed down. The assembly a plinth is limited to only few steps. The base panel holder is also preferred already with the adapter piece at the factory completely assembled and is only depressed on site. The provision of individual parts is unnecessary Consequently.

The plinth holder is as a clamp trained with reset escapement, so that other Attachment approaches for the base panel, for example in the form of molded harpoon bridge attachments, Screw connections or the like are unnecessary. To ensure that the to have a mounted plinth bracket a locking profile, the preferably with the same distance on both sides a vertical plane intersecting its longitudinal axis extends or arranged symmetrically to its longitudinal axis is so that it is at least two-sided on the adapter piece is attached.

The keeper is on to provide the piece of adapter to be fixed to the furniture part in such a way that he from the outside into a corresponding Adapter mold recess can be used and in any Formation of a clamp holding leg, the one end edge overlaps the base panel, with the exception this clamp hold-down leg completely is to be inserted into this recess. To do this this adapter shape recess an internal multi-stage locking profile. The plinth panel holder itself also has one multi-stage locking, as well as training the invention provides on elastically trained Locking legs, which are thus at Depress the hold-down device towards the longitudinal axis of the hold-down can be pressed in. Thus, in the hold-down direction due to the elasticity of the locking legs the plinth holder slightly in Hold-down direction are moved, however, is due the locking teeth in the opposite direction inhibited movement.

Nevertheless, it can be bent open by elastic of the hold-down leg of the plinth holder or by pulling out the base on its lower edge also loosen the plinth panel again, which nobody does requires special manual skills. There the plinth holder at the same height remains, the plinth is then simple Clip it back in position without it being otherwise Adjustment work is required. Otherwise is in the direction across the hold down direction of the plinth cover Skirting board holder through the catch lugs and the attachment lugs secured in the adapter piece.

This can also be done in a simple manner Design the adapter piece in such a way that this too also forms a height-adjustable furniture footrest, so that the fitter on site at that of the furniture manufacturer directly attached adapter piece the furniture foot for example, with a press fit in a support leg holder can plug in. The furniture support leg is preferred variable in length, so that any unevenness can be compensated. The furniture support foot can also be fixed with a zero position in e.g. Shape of a recess be equipped, the zero position in gutter-like Formations of a foot part is located. That offers likewise protection and protection against unintentional turning of the threaded part e.g. in the Zeroing but also during transport.

The fastening device, generally numbered 1 in the drawing has an adapter piece 2 and one generally with 3 numbered plinth holder. The Adapter piece 2 is on attachment lugs 4 on one To fix furniture part.

As particularly illustrated in FIGS. 2 and 5, has the adapter piece 2 for receiving the socket holder one or more groove-shaped Adapter form recesses 5. In Fig. 2 is an adapter piece 2 shown at right angles to each other standing plinth panels are to be attached. In the adapter shape recesses 5 is the plinth bracket 3 either from the front in the direction of arrow 6 (Fig. 2) or from slide in at the top. In the rear area of the adapter recess 5 are attachment lugs 7 with Undercuts formed. These attachment approaches 7 are of locking lugs 8 (Fig. 5) of the plinth holder 3 to reach behind, so that the Plinth panel holder 3 after insertion against the Direction of insertion is secured.

Both the adapter shape recess 5 and the Base bracket 3 each have a locking profile 5.1 or 3.1, each as a multi-stage Sawtooth profiling is formed. When inserting of the plinth holder are the sawtooth profiles complementary so that insert the plinth holder 3 and in the direction of insertion to snap onto the attachment lugs is

As in particular also from Figures 1 and 4 emerges, the base panel holder 3 is in the embodiments as clamp-down device with reset escapement trained and has his Verrastungsprofilierung 3.1 on an elastic trained Locking leg 3.2, which in turn has elastic Supports 3.3 on the holder main part 3.4 is supported.

As can be seen in more detail from Fig. 3, in the shown Embodiment of the holder 3 still a hold-down leg 3.5, a recording room 3.6 to Arrangement of the front edge of the base panel has. In the hold-down leg 3.5 is also another Formation 3.7 designed for the arrangement of a tool. The hold-down leg 3.5 is with a certain Molded elasticity, so that this in the assembled Condition of a plinth by a certain amount Dimension pushed up or bent up elastically can.

After inserting the plinth holder in the The sense described above is based on the arrangement of the plinth by pressing down the hold-down leg to move the plinth bracket down, whereby the locking legs are pressed inwards and on the locking profile 5.1 of the adapter form recess 5 can slide along until the plinth panel is firmly on the floor is supported. The plinth holder is in this position 3 inhibited against a reset in the adapter piece 4 held, when depressing the Base cover hatters 3 automatically the base cover the height measures as the local conditions demand. All of this is just a few simple steps and to be carried out extremely quickly.

As indicated in detail in Fig. 2, can the adapter piece also with a 10.1 indicated plug-in receptacle for a press fit length-adjustable furniture footrest 10 provided be a height adjustment for that Cabinet furniture can be easily and quickly completed can.

In Fig. 6 is the overall designated 1 fastening device when installed under one Arranged base plate 9 of a kitchen furniture element, between them a not shown fixed connection by screws or, preferably, with drive-in or expansion dowels on the top of the Adapter plate 2 is made in an injection molding process be formed together with the adapter plate 2 can.

A footrest 11 is part of the fastening device 1, but in the present case as a separate one Plug element formed, which is press-fitted on the top inserted into a suitable receptacle in adapter 2 is, at the same time on the press fit between Footrest 11 and adapter 2 for security against rotation Care is taken. This can be essentially the case with one cylindrical uptake due to limited non-concentric (flattened, profiled or prismatic Partial areas in the press fit area) can be achieved.

The anti-twist function serves one from below screwed onto a pin part 11.1 of the footrest 11 Foot 12 via a between the pin part 11.1 and the foot 12 arranged movement thread to make it height adjustable by turning, so that the footrest is easy to adjust and thus the Base plate 9 receives the desired height. Preferably is the footrest 11 made of two injection molded plastic parts made and hollow on the inside. You can inside Tool holders, e.g. a screwdriver slot, have, so that a subsequent readjustment if necessary the amount is still possible if the Base plate 9 a suitable, in dash-dotted lines has indicated opening 13 with which a tool can be introduced.

6 further shows a base panel 14 with the help of a locking leg 3.2 of a plinth holder 3 depressed and fixed on top, the receiving space 3.6 of the Locking leg in its width on the wall thickness the base panel is matched and this on the top grips tightly. The skirting board is on the underside opposite a floor surface or installation surface 15 non-positively and positively through a profile seal 16 supported.

The skirting board is on the side, however over the entire depth of the adapter, in the direction of view 6, viewed through the side face 17 held, which acts as a stop surface.

In addition, the foot 12 of the footrest 11 is in near the bottom in its maximum diameter designed so that it also has a bottom Stop for the (vertical) skirting board 14 forms. From the apparent from Fig. 2 symmetry of the Floor plan of the adapter piece 2 also shows that the foot 12 also for a second, parallel to the plane of the drawing 6 is a bottom skirting board Stop can offer that with the one above Side surface of the adapter piece 2 is aligned.

This results in the basic concept of a user-friendly Pre-assembly and a fault-protected Assembly. Becomes a piece of furniture shipped, the bottom plate 9 already underside with a fastener 1 of the type shown is equipped, then this fastener already with the footrest 11 and (at least) a socket holder 3 be equipped, the latter expedient in one as high as possible Starting position is arranged. More loose and Parts that can be lost are no longer required on site.

By turning the foot 2 is the height of the base plate 9 adjust quickly. Then the skirting board 14, hitting adapter 2 and foot 12, and by pressing down the plinth holder 3 fixed in the direction of an arrow 18. Doing so for example a tool like a screwdriver between base plate 9 and locking leg 3.2 set to the latter over some teeth of the locking profile to move down where then it is set.

After assembly, the skirting 14 does not remain only from above through (two) plinth holder on both depressed upper corners, but against of bumping feet or brooms in front or outside through the rear stops adapter piece 2 and Foot 12 supported.

7, 8 and 9 are the pin part 11.1 and Foot 12 of the footrest 11 shown in FIG. 6 closer illustrated. The pin part 11.1 is with his Thread 20 in a corresponding internal thread 21 of the Screwable foot 12. The zero point lock is on a locking lug 17 is molded onto the pin part 11.1. The foot 12 has 12.2 on its upper end edge gutter-like arranged at the same distance Form recesses 12.1 to accommodate the approach 17 in the zero position. When assembling are therefore the corresponding pin parts of each fastening device used in just a few simple steps the zero position with clearly perceptible engagement the approach in one of the recesses 12.1 bring. This is due to this slight locking Pin part also secured against unintentional adjustment This advantage is also e.g. already during transport given.

10 to 14 is an alternative embodiment an adapter piece 2 illustrated in more detail, which makes it possible, together with a Furniture footrest 11 once to form a decorative foot and to be used once as a plinth holder. To do this, first has the adapter piece 2 in analog Way as in the embodiment of the adapter piece 2 for receiving the plinth panel holder a groove-shaped adapter shape recess 5 for Supporting the plinth holder 3. In the rear Area of the adapter recess 5 are again Fastening lugs 7 shaped with undercuts. These attachment approaches. 7 are from locking lugs 8 of the plinth holder 3 to reach behind.

In an analogous manner as also indicated in FIG also in this embodiment, the adapter piece 2 also with a plug receptacle indicated at 10.1 for one with e.g. Press-fit insertable variable in length Furniture footrest 10 provided altogether with the screw-in, adjustable in height 10.2 a furniture foot 11 together with the adapter piece 2 forms (Fig. 11, 12, 14). The Adapter mold recess 5 is in an area of Adapter piece 2 formed in which this is a level Has contact surface 2.1 as the fastening side edge. Outside of this fastening side edge 2.1 Decorative surfaces 2.2 formed as they are in detail 10 to 14 also emerge in more detail. Of course are other geometric contours possible as decorative surfaces.

Overall, this adapter piece 2 together with parts 10 and 10.2 from FIGS. 11 and 14 visible ornamental foot form, the flat contact surface 2.1 with the recess 5 in the case where no base panel is provided from the visible surface of the cupboard furniture, i.e. towards the back is aligned. Alternatively, however, is also like this 12, this furniture decorative foot is also illustrated 11 also to determine the base panel 14 with bottom seal 16 to use.

It is in a particularly preferred training also the lower area of the base panel 14 over a socket cover support designed as a screwing tool (FIG. 13) 24 supported. The plinth support 24 in their training as a screwdriver used equally to the foot section 10.2 to screw into part 10.

As can be seen in more detail from FIGS. 10 and 11, can also the adapter piece 2 also form recesses 25 have to arrange connectors 26 which, for example, according to the push button principle, i.e. can be introduced under friction, after they are previously connected to the cabinet furniture. This Connections can also be used, for example, as Use locking or adjustment aid during assembly. Alternatively it is also possible, for example, only on one Cupboard furniture to provide such a connector (Fig. 11). to position and fit the other Cupboard furniture to introduce a screw 27.
