EP2642891B1 - Bracket adapter with connecting fitting - Google Patents

Description

The invention relates to a Zargenadapter for a side wall frame of a drawer, with a connecting fitting for releasably securing a plate-shaped furniture part, in particular a front panel, at this angle, preferably rectangular, aligned side wall frame, wherein the connection fitting has a support means which is provided with an abutment which is in releasable engagement with a locking device,.

A generic connection fitting is from the EP 0 066 893 B1 known. The connection fitting shown is characterized by the fact that it is compact and that with him a solid connection between two plate-shaped furniture parts to be joined together can be realized, which can be easily solved by an integrated in the connection fitting release lever. Advantageously, the possibility of automatically establishing the connection by axially inserting the corresponding support unit.

On the other hand, less favorable appears in this state of the art, the spring property of the assembled system, as shocks are absorbed relatively unsprung on the connection area, which can lead to damage to the interconnected furniture parts in extreme cases.

A connection fitting, which also has a connection fitting with "automatic locking" in the manner of EP 0 066 893 B1 uses, but to release no integrated release lever but a recording in the locking lever, which allows using a separate tool, such as a screwdriver, a reset, is also from the EP 0 740 917 B1 known. It is moved by the axial insertion of the screwdriver into the receptacle when releasing a locking member from the locking lever and only then can be run over by applying a transverse force of the dead center of the release path. This is particularly disadvantageous that for releasing the front panel always a tool must be kept.

The prior art is further on the WO 2010/115346 A and the DE 1 ^ 0 2007 053 637 A referenced, which also disclose the features a) to e) of claim 1 as well as feature f) but no operability of the locking lever by hand.

The invention has, starting from the generic EP 0 066 893 B1 the task of further improving the connection fitting of the frame adapter.

The invention solves this problem by the subjects of claims 1 and 9.

The subject matter of claim 1 makes it possible to dispense with a tool such as a screwdriver for releasing the locking lever particularly advantageous, since the release lever is particularly practical space-saving integrated with the frame construction.

Thereby, the actuation of the release lever on both sides of the drawer, i. on both side frames, at the same time, so that the front panel can be solved safely and without damage by a user. The invention accordingly also provides a drawer with two side frames, a front panel and two of the connection fittings according to the invention.

In this case, further functions are advantageously integrated into the release lever according to variants of the subclaims, which further improves the handling and safety properties of the connection fitting

Thus, according to claim 2, a first link in the mounting base portion is formed, which is in register with a second link in the locking lever, wherein a pin passes through both scenes, which is movable in both scenes. This feature makes it possible in a particularly simple manner, an advantageous interaction between the components locking lever and mounting base portion.

According to claim 3, the first backdrop is an arcuate backdrop in the mounting base portion and the second backdrop an angular backdrop in the locking lever, with a überdrückbarer dead center is formed for the pin through the angular backdrop. In this way, the mechanism necessary for the function of locking the locking lever can be implemented in a particularly simple and reliable manner in practice.

Preferably, the pin is - preferably in an opening - arranged on the release lever, which makes it possible to include the release lever with simple structural means in the interplay of the scenes on the locking lever and the mounting base portion with.

It is also advantageous if a head is formed on the pin, so that the locking lever is guided on the mounting base portion in its backdrop when the locking lever moves between the open position and the locking position.

By the subject matter of claim 8, which is to be considered as a development of claims 1 to 7, the risk of damage to the front panel and possibly the drawer mechanism is reduced by impact on the front panel in a simple manner, since the locking lever of the drawer mechanism resiliently in the field can move its pivotal mounting.

Furthermore, the resilient connection fitting allows the front panel - if this is pivotable according to their angle to the other plate-shaped furniture part can be adjusted without having to solve the connection during adjustment, since the pivot bearing compensate for the corresponding movement of the front panel and record can. This is not possible if the pivot bearing is designed as at least in the practical sense as by the expert "backlash" to be considered fixed bearing.

Advantageous embodiments of the invention can be found in the dependent claims.

Each connection fitting 1 has - see Fig. 1 - Two inter-engageable, corresponding - functional units on: a support means 2 and a releasably engageable with the support means 2 locking device. 3

The support device 2 is fixed to a first plate-shaped furniture part, which - see Fig. 3-5 - Is preferably designed as a front panel 4 of a drawer 5. This drawer 5 can be inserted into a furniture body 6 of a piece of furniture 7, in which it is displaceably guided so that it can be pulled out of the furniture body 6 into an open position and pushed out of it into a closed position (see FIG Fig. 3 and 4 ,

The locking device 3 (see Fig. 2 and 6 and 7 and 8) on the other hand is designed to be attached to a second plate-shaped furniture part, which is preferably formed as a side frame 8 of the drawer 5. The plate shape of the side frame is realized here by a metallic double-wall cover 9, which is set via one or more Zargenadapter 10 and which can be locked in a conventional manner to the one or Zargenadaptern 10, for example with mounting means such as screws or locking means or the like. The Zargenadapter 10 also serve to receive a drawer bottom 11 ( Fig. 6 ) on mounting contours 12 ( Fig. 2 ) and for placement on a rail construction, not shown here, with which the drawer is guided on the furniture body displaceable.

Each drawer preferably has two of the frames 8 and two of the connecting fittings 1, so that the front panel 4 is connectable in two areas via one of the support means 2 with the corresponding locking means 3 on the corresponding two side frames 8 and is connected in the mounted state.

The construction of the carrying device 2 is largely arbitrary within the scope of the present invention. However, it must at least on the first plate-shaped furniture part, such as the front panel 4, be fixed and have an abutment element, for example, a suitable recess or a horizontally extending in the installed position pin 13th

The locking device 3 has a base unit (see also Fig. 2 ), in the form of a base angle 14, which is fixed with a leg (sections 15a, b) on an upper mounting surface 16 of the frame adapter 10 in the installed position, for example by welding. This setting could also be done by other connecting means such as screws, further, the base unit could also be integrally integrated in the frame adapter 10 (not shown here).

It should be noted at this point that terms such as "top" and "bottom" are not generally to be understood as limiting. Rather, they understand the usual installation and structure of a piece of furniture, as they are in Fig. 2 is reproduced.

The thigh ( Fig. 2 ) is here divided into two leg portions 15a, b, between which there is a free space to allow out of the mounting surface 16 upwardly projecting contours of other, not further explained here functional elements.

The mounting surface 16 has in the front part, i. in the direction of the support means 2, an opening 17 through which still to be explained functional elements of the locking device 3 protrude into the frame adapter 10.

The frame adapter 10 has in a view perpendicular to the front panel plane substantially a U-shaped cross-section. Preferably, it is bent from a sheet, wherein the mounting surface 16 is formed by the shorter leg of the U. In addition, the mounting contours 12 of the frame adapter 10 are in front of the drawer bottom 11. Between the two longer legs 18, 19 of the Zargenadapters a free space 20 is formed. This free space 20 is dimensioned such that a user can reach into it from below with his fingers.

The leg portions 15a, b have a mounting base portion 21 extending perpendicular to the mounting surface 16. On the mounting base portion 21, a locking lever 22 is articulated movable, which is movable from a release position to a locking position.

The locking lever 22 is preferably always completely within the frame, so that no part of the locking device 3 extends into the front panel 4.

The locking lever 22 has a hook portion 23, which serves to engage behind the corresponding abutment, preferably the pin 13, on the support means 2. The locking lever 22 is designed as a lever mounted on one side. Its pivot bearing 24 is located on its side facing away from the front panel 4 side. The locking lever 22 is preferably penetrated in this area at an opening 45 by a pin 25, which preferably passes through a slot-like opening 26 in the mounting base portion 21.

The opening 26 has a dimension that is significantly larger than the diameter of the pin 25 at least in the X direction, so that the pin 25 passes through the opening 26 with play.

At the mounting base portion 21 and the locking lever 22 mounting contours 27, 49 are formed as hooks on which a spring, here a coil spring 28, with their ends, which can form mounting arches, is mounted. The coil spring 28 is almost horizontal. Its one end is fixed in the mounted position, preferably above the opening 26 in a recess 46 of the mounting base portion 21 and its other end is preferably located approximately midway between the pin 25 and the hook portion 23rd

Thus, the coil spring 28 pulls the locking lever 22 in an upper locking position, in which, when the hook-shaped portion engages behind the abutment on the support member or on the support means 2, which is a plate-shaped component fixed to the other, so here the front panel 4 on the a side frame 8.

Due to the mounting of the pin 25 on the rear reveal of the preferably slot-like opening 26 with play in the opening 26, the end of the locking lever 22 with the pin in the opening 26 can move something, especially in the direction parallel to the side frame 8 and perpendicular to the front panel 4th

This is particularly advantageous because it is prevented by the action described that hard shocks are forwarded to the front panel immediately with full impulse to the side frame 8. The shock pulse is rather deprived of kinetic energy 28 by the interaction of the bearing clearance and the spring. Thus, the connection fitting 1 according to the invention significantly reduces the risk of damage to the side frame construction and the fastening of the front panel 4 with the pin sections 42, 43 of the support device 2 of the connection fitting 1 in a simple manner.

It is advantageous if the play in the pivot bearing 24 in at least one direction, preferably in the mounting direction or here "X direction" ( Fig. 1 ) in the range of 0.3 to 3 mm, more preferably in the range of 0.5 to 2 mm. The play can be formed at the opening 26 and / or in the connection area between the pin 25 and the locking lever 22.

To release the locking lever 22 from the connecting position, as they Fig. 1 shows, is used in the locking device 3 integrated release lever 29th

The release lever 29 preferably has an L-shape in a side view. It has a lever arm 30 and a release arm 31 which is aligned at an angle, here almost at right angles, to the lever arm 30. The release arm 31 is also in a view perpendicular to the side view (see also Fig. 2 ) trained here in itself. Between the lever arm 30 and the release arm 31, a control surface 51 is arranged in the angle enclosed by these arms, which is arranged almost vertically in the open position of the locking device 3.

The lever arm 30 is advantageous here with its end to the mounting base portion 21, preferably to the front panel 4 and the support means 2 close to the hook portion 23 by means of the pin 32, the corresponding openings 34 and 36 in the mounting base portion 21 and in the Release lever 29 passes through, hinged. In the mounting base portion 21, an arcuate gate 44 is formed, which is in an overlap with an angular gate 50 in the locking lever 22 so that the pin 33 both scenes 44, 50 passes through and in which the pin 33 at a distance around its pivot point (the advantageous here in the region of an optionally provided, the arrangement stabilizing material doubling of the element 21 is) formed by the storage in the openings 34, 36 moves, with a überdrückbarer dead point is formed by the angular gate 50 and wherein the pin 33 in an opening 35 on the Release lever 29 is arranged. Further, a head 38 is formed on the pin 33, so that the locking lever 22 is securely guided on the mounting base portion 21 in the link 44 when the locking lever 22 moves between the open position and the locking position.

The release arm 31 projects downwards through the opening 17 into the free space and can be gripped there with a finger.

When locking, ie when inserting the support means 2 is actuated by the pin 13 of the release lever 29 on the control surface 51 and thus the pin 33 moves over the dead center of the link 50. As a result, the locking lever 22 is released and pivots by the force of the coil spring 28 upwards, the pin 13 is engaged behind.

Fig. 7 illustrates that the frame cover 9 may have a side opening 48 to allow lateral access to the shutter adjustment on the support means 2.

If the release arm 31 is pulled in the direction of the carrying device 2 or the front panel 4, the locking lever 22 is pulled against the force of the spring 28 from the locking position or its upper position to an open position or lower position.

Preferably, the locking and locking lever 22 by the pin 33 on the release lever 29 so far pivotally that a dead center in the gate 50 can be overcome, so that the locking lever 22 can remain in this position in an open position after a corresponding movement, which is particularly facilitates the initial assembly, since in such a way the support means 2 with the front panel 4 is first brought into a mounting position in the locking device. By a sufficiently large force against the direction X on the front panel 4 then the support means 2 by means of the pin 13, the release lever 29 on the control surface 51 and thus the pin 33 move over the dead center of the gate 50, so that by the spring 28 of the locking lever 22 is pulled into its locking position, in which the hook portion 23 engages behind the abutment - here the pin 13 - on the support means 2.

At the free lower end of the release lever 29, so the release arm 31, here at a bend of the same, a resiliently resettable plastic shoe 39 may be attached, which makes the gripping of the release lever 29 more pleasant. Preferably, this plastic shoe 39 also realizes an additional function.

On the plastic shoe, a sliding surface 52 is arranged in the corner region between grip surface 53 and securing surface 40, which initially abuts a corner region 41 of the locking lever 22 when the release arm 31 is pulled, and then slips over this corner 41 when a clearly perceptible, sufficiently high operating force is applied will, ie the Kunsstoffschuh 39 is pivoted against its spring force.

Since the pivoting of the plastic shoe 39 is required to overcome the corner region 41, 29 is by the user when not operating the release lever such an additional safeguard against unintentional release of the locking lever 22 is realized from its locking position, for example by pure shock load on the front panel 4, wherein the plastic shoe 39 abuts in this case with its locking surface 40 to the lower edge of the locking lever 22, so the release lever 29 can not pivot so far in that the coupled locking lever with its hook section 23 can release the pin 13 of the carrying device 2.

This connection becomes particularly clear from the Fig. 10 - 15 or. Fig. 1 , Which side views of the connection fitting from Fig. 1 With ( Fig. 10 . Fig. 1 ) and then without a frame adapter ( Fig. 11 . 12 . 13 . 14 . 15 ), whereby the type of temporally successive snapshots ( Fig. 10 . 11 . 12 . 13 . 14 . 1 or 15) the movements when mounting the support part 2 in the direction -X (see Fig. 1 ) are illustrated on the locking part 3 and in particular also the above-described Überasten of the plastic shoe 39 is illustrated at the corner 41.

Finally, it should be noted that the support member 2 here with one or more dowel-like pin portion (s) 42, 43 in openings of the front panel 4 can be fixed (clamping and / or adhesive). Alternatively, it would also be possible to attach the support member 2 to a front panel 4 in other ways, so by means of screws (not shown here). This connection is significantly relieved by the inventive device described above and thus increases the service life of the furniture. <B> reference numerals </ b> connecting fitting 1 support means 2 locking 3 front panel 4 drawer 5 furniture body 6 Furniture 7 Drawer side 8th Double wall covering 9 frame adapter 10 Drawer base 11 mounting contours 12 pen 13 base angle 14 leg sections 15a, b mounting surface 16 opening 17 leg 18, 19 free space 20 Mounting base section 21 locking lever 22 hook section 23 pivot bearing 24 pen 25 opening 26 mounting contour 27 coil spring 28 release lever 29 lever arm 30 release arm 31 pencils 32, 33 openings 34 to 37 head 38 Plastic shoe 39 securing face 40 corner 41 pin sections 42, 43 scenery 44 opening 45 recess 46 openings 47, 48 mounting contour 49 scenery 50 control surface 51 sliding surface 52 grip 53
