Description

The invention relates to a side frame for a drawer.

From the prior art is a side frame with a locking device for releasably securing a plate-shaped furniture part, in particular a front panel on the side frame, wherein the front panel has a support means which can be brought into releasable engagement with the locking device. A side frame of this kind is from the DE 10 2010 060 722 A1 known. The connection fitting of this prior art has proven itself in practice well and is characterized in that a base portion is mounted on a Zargenadapter a side frame of a drawer or is formed thereon and that a manually operable release lever is hinged to a locking lever and the base portion and extends into a free space in a frame adapter so that it is manually operable in the free space by a user. However, there is a need for further optimization with regard to use on relatively high side frames and front panels.

In the DE 20 2009 014 811 U1 a connection fitting for releasably connecting a first furniture part is described with a second furniture part. The furniture fitting has a receiving element and at least two fastening elements, wherein the receiving element is associated with a first furniture part and the at least two fastening elements a second furniture part, or vice versa. The receiving element has a locking device for releasably holding the at least two fastening elements, wherein the at least two fastening elements can be locked together in the receiving element. The locking device of the receiving element has at least two by a force accumulator, preferably a spring, acted upon or acted upon locking elements which can be locked with the fasteners.

On DE 20 2009 014 811 is problematic that the operation of the fastening device between the front panel and side frame or drawer or releasing the locking of the connection between the front panel and side frame only with an additional tool, such as a screwdriver is possible.

From the DE 298 18 651 U1 a fastening device for attaching a front panel to drawer is known. The fastening device has a front panel and a part of the respective drawer connecting Dübelteil. The dowel part has one or more in associated holes of the front panel insertable expansion dowel, with expansion screws are provided which are insertable through an opening in the dowel part in the associated expansion dowel and each rotatable by means of an actuating lever in the expansion dowel and thereby spread the expansion dowel. The actuation of the operating lever is thus carried out without the aid of a tool "by hand". At the DE 298 18 651 U1 is disadvantageous that for each Zargen- or aperture height stored a geometrically appropriate variant of the fastening device and kept ready during the assembly of a drawer or picked.

From the US 6, 234, 596 B1 a connection fitting for higher drawers is known, which is connectable in two places with a front panel, wherein in each case a combined used for locking and releasing lever is provided at the opposite ends of a base body which extends between the two levers. The disadvantage is that this connection fitting requires a relatively long base body that connects the two levers that he is not suitable for a variety of drawer heights and that he is not mountable to carrying devices of various kinds, since he himself has a kind of mounting pin, which in a bore of Front panel must be introduced, which is not suitable for narrow front panels.

The technological background is still the WO 2012/169982 called.

The invention has the object before this state of the art to further develop the side frame described above such that it can be used in a simple manner on high drawers.

The invention achieves this object by the subject matter of claim 1. In addition, the invention provides the subject matter of claim 12.

The two defined in claim 1 locking devices in each of the side frames are mirror-symmetrical to each other. Since mirror-symmetrically designed locking devices are provided for lower right hand drawers anyway, it is possible to provide these two locking devices on high drawers on each side once each. This avoids that for two side frames of a drawer a total of four different locking devices must be made.

In an advantageous embodiment of the invention, both locking devices are each independently operable by a respective separate release lever, which is operable in each case with a single hand. This advantageously eliminates the need for a tool for releasing the lock.

The locking means are arranged facing each other in a further advantageous embodiment of the invention, so that their release lever can be solved in each case advantageously on one side of the drawer and the locking means of a side frame with one hand. As a result, the handling of the locking devices of the connection fittings is advantageously facilitated. Advantageously, a tool-free disassembly of the front panel is possible. But supporting a tool for disassembly can be used.

According to a further embodiment of the invention, a handle may be provided to actuate the two release levers of the two locking devices simultaneously. The handle can also be arranged so that a displacement or removal of the side frame is not necessary. Advantageously, a tool-free disassembly of the front panel is possible.

Training and further education, which contribute to the compact design advantageous, are given in the claims 9-11.

In Fig. 1 a box furniture 2 is shown. The cabinet furniture 2 has a furniture body 3. In the furniture body 3 -here exemplary-three drawers 4, 5 are used. The drawers 4, 5 are guided displaceably in the furniture body 3, so that each of the drawers 4, 5 each pulled out of the furniture body 3 in an open position and again pushed out of this into a closed position.

The in Fig. 2a and b illustrated drawer 5 has a first plate-shaped furniture part, which is preferably designed as a front panel 6 - here a relatively high front panel 6 -. The drawer 5 has at least a second plate-shaped furniture part, which forms one of two side frames 1a, 1b of the drawer 5. In the following example, the drawer 5 is described with two side frames 1a, 1b. The side frames 1a, 1b are preferably constructed in each case two-shelled. Here, an outer shell 11a, 11b in an inner shell 10a, 10b guided displaceably and the inner shell 10a, 10b forms with the outer shell 11a, 11b each have a narrow cavity. Furthermore, the drawer 5 still has a rear wall and a drawer bottom 12. Preferably, but not necessarily, the outer shell and the inner shell are made of aluminum. According to a particularly preferred embodiment, the outer shell and the inner shell are formed as extruded aluminum profiles. It is further preferred that the outer shell and the inner shell form a very narrow side frame, which is preferably narrower than 15 mm, in particular narrower than 12 mm. Especially with such narrow side frames, the invention can be used advantageously.

In Fig. 2b is the outer shell 11b of the operator of the drawer 5 seen from left side frame 1b of the drawer 5 is not shown and the inner shell 10a of the operator of the drawer 5 seen from right side frame 1a not shown.

Each of the side frames 1a and 1b respectively has two connection fittings 7a, 7b with which the front panel 6 can be attached to the side frame.

For this purpose, the front panel 6 per connection fitting 7a, 7b via a support device 8 in each case with a corresponding locking means 9a, 9b connected to the corresponding side frame 1a and 1b connected or connected in the assembled state.

The locking device 9a, 9b of the connection fitting 7a, 7b can be attached to the side frame 1a, 1b of the drawer 5 in different ways. In the case of double-walled side frames 1a, 1b, fastening of a respective base plate 18 of the locking device 9a, 9b preferably takes place in the inner shell 10a, 10b of the side frame 1a, 1b, preferably by a forming process, particularly preferably by pressure-joining with pre-punching or by clinching with pre-punching. Alternatively, other reversible and irreversible mounting options are conceivable.

The structure of the support means 8 can be realized in the context of the present invention in a variety of ways. It must be on the first plate-shaped furniture part, such as the front panel 6, fixed or fixed and have an abutment element, for example, a suitable recess or a horizontally extending in the installed position pin 14. The support means 8 is z. B. with one or more dowel-like pin portion (s) (not shown here) in openings of the front panel 6 fixable (clamping and / or adhesive). Alternatively, it would also be conceivable to fasten the carrying device 8 to the front panel 6 in another way, for example by means of screws (see Fig. 5d ).

In Fig. 5a the drawer 5 is shown with mounted or locked front panel 6 and pushed back outer shell 11b of the side frame 1b. The locking device 9a, 9b is therefore each in a locking position. The locking device 9a, 9b each have a release lever 22. The release lever 22 is thus also in the locked position.

In Fig. 5b the drawer 5 is still shown with locked front panel 6 and pushed back outer shell 11b of the side frame 1b. As a result, the respective release levers 22 of the locking means 9a, 9b have been moved toward the release position.

In Fig. 5b the drawer 5 is shown with the side panel 1 a, 1 b further dissolved front panel 6 and pushed back outer shell 11 b of the side frame 1 b. As a result, the respective release levers 22 of the locking means 9a, 9b have been further moved toward the release position.

In Fig. 5d the drawer 5 is shown with partially dissolved front panel 6 and pushed back outer shell of the side frame 1b. Accordingly, the respective release lever 22 of the locking device 9a, 9b are in a release position, so that the front panel 6 can be removed from the drawer 5.

It is advantageously provided that each of the side frames 1a, 1b in each case in addition to the first locking device 9a has a second locking device 9b, said second locking device 9b arranged mirror-symmetrically above the first locking device 9a on the inner shell 10a, 10b of the side frame 1a, 1b and / or is formed and in the cavity between the inner shell 10a, 10b and the outer shell 11a, 11b of the side frame 1a and 1b is arranged.

By the term "mirror-symmetrical" is meant here preferably that the first locking device 9a perpendicular to a plane of symmetry (which extends through the line XY and preferably longitudinally through the center of the drawer or otherwise perpendicular to the side frame 1a, 1b; Fig. 3 ) is mirrored, so that the resulting mirror image coincides with the position and position of the second locking device 9b. The locking means are in particular constructed such that the lower locking means of the left side frame is identical to the upper locking means of the right side frame and vice versa. This is in Fig. 2b . Fig. 3 respectively. Fig. 4 as well as in the FIGS. 5a to 5d always clearly visible.

Advantageously, both locking devices 9a, 9b are each independently operable by the respective separate release lever 22, which is in each case manually operable by a user. The distance between the release lever 22 to each other is preferably chosen so that both release lever 22 can be actuated simultaneously by different fingers of one hand.

By using two locking devices 9a, 9b in different positions / orientations, a front panel attachment even with high front panels 6 simple, inexpensive and thus advantageous to be realized. A provision of several height variations of locking devices 9a, 9b thereby eliminated in an advantageous manner.

In the Fig. 2b . Fig. 3 respectively. Fig. 4 as well as in the FIGS. 5a to 5d is in each case easily recognizable that the locking devices 9a, 9b respectively arranged facing each other in the respective side frames 1a and 1b, so that their release lever 22 respectively on one side of the drawer 5 and the locking means 9a, 9b of the side frames 1a and. 1b can be solved advantageously with one hand. As a result, the handling of the locking devices 9a, 9b of the connecting fittings 7a, 7b is advantageously facilitated. Advantageously, a tool-free disassembly of the front panel 6 is possible.

Alternatively, a handle (not shown here) may be present to simultaneously actuate both release levers 22 of the two locking devices 9a, 9b. The handle can also be arranged so that a displacement or removal of the outer shell 11a, 11b of the side frame 1a, 1b is not necessary. Advantageously, such a complete tool-free disassembly of the front panel 6 is possible.

Hereinafter, the structure of the particularly compact design preferred locking device based on FIGS. 6a to 6d described.

The locking device 9a has a movably hinged, spring-loaded locking lever 17, which is movable on a base plate 18 from a release position into a locking position.

The locking lever 17 is in the assembled state of the locking device 9a or 9b or the side frame 1a, 1b preferably always completely within a side frame 1a, 1b, so that no part of the locking device 9a extends into the front panel 6. In Fig. 5a to 5d , the drawer 5 is shown in each case with pushed back outer shell 11b of the side frame 1b. By simple and thus advantageous displacement of the outer shell 11a, 11b of the side frame 1b and 1a, respectively the locking devices 9a and 9b in the locking position of the locking device 9a or 9b or concealed hidden front panel 6 advantageously hidden from the outside.

The in Fig. 6a, 6b and in particular in Fig. 6d clearly visible locking lever 17 has a hook-shaped portion 29 which is adapted to engage behind an abutment or the pin 14 on the support member or on the support means 8 in the locking position of the locking device 9a. The locking lever 17 is also pivotable relative to the base plate 18 on a bolt 27 and rotatably mounted. The locking lever 17 also has a link 28.

On the base plate 18 of the locking device 9a and the locking lever 17 mounting contours 19, 20, preferably hooks, formed on which a spring, here a coil spring 21, with their ends, which can form mounting eyelets, is mounted. Thus, the coil spring 21 pulls the locking lever 17 in an upper locking position. In the upper locking position, the hook-shaped portion 29 of the locking lever 17 engages in the mounted on the front panel an abutment on the support member or on the support means 8, whereby a plate-shaped component is fixed to the second plate-shaped member, so here the front panel 6 on the one Side frame 1a or 1b. Thus, the front panel 6 is releasably fixed to the side frames 1a, 1b.

The base plate 18 has an over the entire longitudinal extent of the base plate 18 extending throughput 30 (or a gradation), which forms a space for receiving the coil spring 21 in conjunction with an opening 31. In addition, the base plate 18 at its two longitudinal edges 32a, 32b a plurality of notches 33, which serve in a forming operation of the inner shell 10a, 10b of the side frame 1a and 1b, the locking device 9a or 9b to attach to this.

The base plate 18 further has a keyhole-shaped recess 34 which is geometrically designed so that it can receive the abutment or the pin 14 on the support member or on the support means 8 or with the abutment or with the pin on the support member or corresponds to the support device 8. This recess 34 prevents in a simple manner that after releasing the locking device 9a, 9b, the front panel 6 can fall down. This ensures that the front panel 6 can be solved manually, without tools and safely on both sides.

The base plate 18 also has a link 35, which is penetrated in the assembled state of the locking device 9a and 9b by a bolt 36, which also passes through the gate 28 of the locking lever 17 and the release lever 22 at the same time. As a result, the release lever 22 is in operative connection with the locking lever 17th

The release lever 22 preferably has an L-shape in a side view. It has a lever arm 23 and a release arm 24, which is aligned at an angle, here almost at right angles, to the lever arm 23. The release arm 24 is also in a view perpendicular to the side view (see also Fig. 6a and Fig. 6d ) trained in itself. Between the lever arm 23 and the release arm 24, a control surface 25 is arranged in the angle enclosed by these arms, which is arranged almost vertically in the open position of the locking device 9a. The release lever 22 is rotatably supported by a bolt 37 on the base plate 18. In this case, the release lever 22 may advantageously be resiliently biased in the locked position, so that unintentional release of the release lever 22 is prevented from the locked position. Furthermore, the release lever 22 may be resiliently biased in the release position to assist in the introduction of the support means 8 in the locking means 9a, 9b of the side frame 1a, 1b.

When latching, i. when inserting the support means 8, the release lever 22 is actuated by the pin 14 on the control surface 25 and thus the bolt 36 moves over the dead center of the link 28. As a result, the locking lever 17 is released and pivots by the force of the coil spring 29 upwards, wherein the pin 14 is engaged behind by the hook-shaped portion 29 of the locking lever 17. As a result, the locking device 9a, 9b is locked and thus the front panel 6 releasably fixed to the side frames 1a, 1b.

The locking device 9b is like the locking device 9a formed and arranged, but mirror-symmetrical to this. <B> reference numerals </ b> Drawer side 1a, 1b box furniture 2 furniture body 3 drawer 4 drawer 5 front panel 6 connecting fitting 7a, 7b support means 8th locking 9a, 9b inner shell 10a, 10b outer shell 11a, 11b Drawer base 12 pen 14 locking lever 17 baseplate 18 mounting contour 19 mounting contour 20 coil spring 21 release lever 22 lever arm 23 release arm 24 control surface 25 bolt 27 scenery 28 Hook-shaped section 29 throughput 30 breakthrough 31 longitudinal edge 32a, 32b notch 33 recess 34 scenery 35 bolt 36 bolt 37 plane of symmetry X - Y
