EP2164363B1 - Drawer frame with a fastening device for a front panel - Google Patents

Description

The present invention relates to a drawer with a fastening device for releasably and preferably adjustable attaching a front panel to the drawer, wherein on the front panel a fitting is preassembled and wherein in the drawer a spring-loaded catch part is arranged, which automatically during insertion of the fitting part Drawer frame pulls out, with a locking device is provided for the catching part.

Furthermore, the invention relates to a drawer or a piece of furniture with a drawer frame of the type described.

Such drawer frames are connectable, for example as Zargenaufsätze with a rail of a pull-out for drawers. These Zargenaufsätze turn have mounting options for a drawer bottom, a drawer rear wall and a front panel. From the European patent EP 0 740 917 B1 the applicant is known a connection fitting for the detachable attachment of a front panel to drawer frames, the front panel or its fitting part is automatically locked by a spring-loaded catch part with the drawer frame. In the assembled state of the front panel on the catch part, a locking bolt is provided, which engages in a notch of the catching part. However, especially with heavily loaded drawers with high front panels, it often happens that the front panels perform a slight tilting movement relative to the drawer units when operating the drawers by the force exerted by the user. This relative movement is undesirable, as this leads to a delayed movement of the actual drawer and therefore insufficiently satisfies the need for optimized movement behavior in some situations.

From the EP 0 761 130 A2 a mounting fitting for front panels of drawers has become known, wherein a pivotable locking element engages positively connected to one of the front panel associated tab-shaped approach.

Object of the present invention is therefore to provide a drawer frame of the type mentioned, with in addition to a secure attachment of the front panel preferably also varied settings of the front panel should be possible.

This is inventively achieved in an advantageous embodiment in that the locking device is designed as a clamping device.

In the simplest case, this locking can be done to the effect that a bolt is brought into operative connection with the catch part, that the fitting part of the front panel is held not only on the spring force of the front fitting, but is additionally locked in position stable against relative movement in the locked position. In this way, the locked with the catch part fitting part of the front panel can be connected to the drawer rigid and essentially free of play.

According to a preferred embodiment it can be provided that the locking device automatically locks the catching part in its position holding the fitting part. It is therefore not necessary to activate the locking device separately by additional manual operation.

In a preferred embodiment of the invention can be provided that the locking device for adjusting the position of the front panel relative to the drawer frame is releasable. Here, the front panel remains attached via the usual connection fitting to the drawer, however, the selective position of the front panel can be adjusted relative to the drawer frame targeted.

From a constructive point of view, the design can be such that the locking device has at least one movable, preferably rotatable about an axis, wedge element which locks the catch part in a first operating position and releases the catch part in a second operating position. In this context, it may be advantageous if the wedge element in the first operating position between the catching part and one of the drawer frame associated stop is in clamping connection. In addition to a non-positive locking and a positive connection for indirect or immediate locking of the catch part can be provided.

According to a further embodiment of the invention can be provided that the wedge element at least one guideway, preferably a control cam or a sliding guide, along which the wedge element can run off the stop. The shape of the guideway is chosen so that the force acting on the catch part is variably adjustable, which can be made possible for example by a curved or curved shape thereof. In this way, on the one hand the wedge element between a fixed stop and the catching part can be brought into a wedged position and on the other hand, the wedge element - preferably by rotation thereof - be moved to a position in which the fitting part of the front panel only on the spring exerted Force is held on the catch part. In this context, the arrangement of a spring (either by the spring of the catching part or possibly also by a separate spring), which presses the wedge element automatically in the direction of the wedge position.

Fig. 1 shows a perspective view of a cabinet-shaped piece of furniture 1, which includes a furniture body 2 and 3 movable relative thereto drawers. The drawers 3 have lateral drawer 4 and at least partially above arranged Aufzzzargen 5 on. Furthermore, the drawer 4 are formed such that they are connectable to a front panel 6, a drawer bottom, a drawer rear wall and with a Ausziehführungsgarnitur not shown for drawers. In particular, in the uppermost illustrated drawer 3 of the furniture 1, the front panel 6, the height of the drawer 4 considerably exceeds, it may happen that upon actuation of a handle in the region of the upper edge of the front panel 6, a tilting movement of the front panel 6 relative to the drawer 4 due to acting Leverage is triggered because the front panel 6 - as usual in the prior art - is held only by a spring-loaded tilting fitting on the drawer 4. Based on this problem, the present invention proposes now to provide an improved fastening means of the drawer 4 for the articulation of the front panel 6, which will be described in more detail in the following figures.

Fig. 2 shows a perspective view of the drawer 3 with removed front panel 6. The drawer 3 has side drawer 4 and plate-shaped Aufsatzzargen 5, which are provided to increase the receiving volume of the drawer 3. In addition, a drawer bottom 7 and a rear wall 8 can be seen. The drawer frame 4 has a fastening device 9 on, which is arranged in the front region of the drawer 4 and completely behind the front end side thereof. It can be seen that the drawer frame 4 is formed as a double-walled hollow chamber frame, wherein all components of the fastening device are arranged in the hollow chamber.

Fig. 3 shows the front portion of the drawer 4 with the fitting to be mounted on the front panel 6 fitting 10. The fitting 10 has dowels 11 for anchoring to the front panel 6, not shown. In the illustrated embodiment, the height of the fitting part 10 exceeds the height of the drawer 4, wherein the projecting beyond the drawer 4 section 12 of the fitting 10 for reasons of stability, at least in sections has a U-profile. At the top of the drawer 4 a continuous groove 13 is formed, in which the top frame 5 is inserted with its underside. Evident is also an opening A at the top of the drawer 4, which is provided for the passage of the fitting part 10. The fitting part 10 has a holding part 14, which is in latching connection with a catching part 15 of the fastening device 9. The catching part 15 is acted upon by a spring not visible in this figure. In the event that the fitting 10 should be solved, only a screwdriver is to be attached to the side receptacle 16 and rotate clockwise, after which the fitting 10 is released from the fastening device 9.

Fig. 4a - 4c show temporal sequences of the connection process between the front panel-side fitting part 10 and the fastening device 9 of the drawer 4 in a side view. Evident is the fitting part 10 with its laterally projecting holding part 14 and a side adjusting device 17, through which the front panel 6 in the mounting position laterally to the drawer frame 4 is adjustable. Fig. 4a shows the beginning of Einrastprozesses, wherein a acted upon by a spring 18 catching part 15 remains in a cocked ready position. When inserting the holding part 14 takes a retraction of the holding part 14 in the drawer 4 and an automatic latching of the two parts 14, 15, wherein the catch member 15 is pivoted about an axis of rotation in a clockwise direction. According to the invention, it is now proposed to provide an additional locking device 19 which comprises at least one wedge element 19a. The wedge member 19a is rotatably mounted and has a guide track 21 in the form of a curved cam on a fixed stop 20 in the form of a Bolzens can run. In Fig. 4a the wedge element 19a is in the unlocked position.

Now, if the holding part 14 merges with the catching part 15, so the catch member 15 pivots by the action of the spring 18 in a clockwise direction, whereupon the fitting part 10 is pulled in its entirety to the drawer 4 towards. This position is in Fig. 4b shown. It can also be seen that the wedge element 19a with its guide track 21 has also been pivoted by the action of the spring 18 in an automatic manner in the clockwise direction, so that the wedge element 15a is now wedged firmly between the rigid stop 20 and the pivot point S. In this way, the catch member 15 is additionally locked in addition to the acting spring force, whereby the front panel 6, not shown here, is connected to the drawer frame 4 substantially free of play. In this way, an undesired relative movement between the front panel 6 and drawer 4 can be largely minimized upon actuation of the drawer 3.

Fig. 4c Although still shows the locked position between fitting 10 and catch part 15, but the wedge member 15a was loosened by a release device 23 from the rigid clamping connection between pivot point and stop 20, so that an adjustment of the relative position of the fitting part 10 (and thus the front panel ) is possible. The release device 23 is formed in the embodiment shown by a height-adjustable slider which is vertically movable by a screwdriver while the wedge element 15a pivots back slightly. At the wall, not shown here, the drawer 4, namely an opening is provided which allows the passage of a screwdriver. In this case, the screwdriver comes to the teeth of the release device 23 to the plant, with a permanently connected to the release device 23 pin 30 causes a height adjustment of the wedge element 19a from the frictional connection out.

Fig. 5a - 5c show starting from Fig. 4c a fitting part 10 shown in two different pivot positions Fig. 5a As can be seen, by attaching and rotating a screwdriver, the release device 23 is adjusted so far up until the screwdriver can slip through the release device 23, whereby one in the second depth position of Drawer frame 4 arranged inclination adjustment 24 is accessible or adjustable. This inclination adjusting device 24 comprises a gear with an adjusting wheel, wherein a rotation of the same causes a linear movement of a running along the top of the drawer 4 lever 25a, which rests in the region of the end face of the drawer 4 on the fitting part 10. If now the lever 25a is moved by an adjustment of the inclination adjustment device 24, an opposite movement of the lever 25b arranged on the underside of the drawer frame 4c is effected via an intermediate lever 25b mounted on the pivot point R. The lever 25c likewise extends in the area of the front side of the drawer frame 4 on the fitting part 10 is applied. In other words, in this case a rocking motion is exerted on the fitting part 10 of the front panel 6. Fig. 5a shows now in an assembly position to the drawer 4 towards inclined position of the fitting part 10, while Fig. 5b - by opposite rotational movement of the tilt adjustment 24 - a tilted outward position of the fitting 10 shows.

Fig. 5c now shows a tilted fitting part 10, wherein the locking device 19 has wedged in the form of the wedge member 19a again automatically between the pivot point S and the stopper 20. Automatically therefore, since when pulling the screwdriver out of the drawer 4, the wedge member 19a by the force of a spring (either by the spring 18 of the catch member 15 or by a separate spring) back into the first operating position - which corresponds to the locking position of the wedge member 19a - is pressed. It can be seen in Fig. 5c Also, a height adjustment device 26 in the form of an eccentric, with the height position of the latched fitting part 10 is adjustable relative to the drawer 4. This height adjustment device 26 is known from the prior art and need not be described in detail at this point.

Fig. 6 shows an exploded view of the components used, all of which can be arranged inside a hollow chamber drawer 4. On a fixedly connected to the drawer 4 base plate 27, a mounting plate 28 is arranged, which is relatively movable via the height adjustment device 26 in the form of an eccentric. Evident is also the lever mechanism with the levers 25a and 25c, which are coupled to each other in motion via the deflection lever 25b. The spring 18 is used to act on the catching part 15, not with the here shown holding part 14 of the fitting part 10 can be latched. The locking device 19 comprises a wedge element 19a in the form of a pivotable lever which can be wedged in the mounting position between the stop 20 and the axis of rotation S. For unlocking the wedge element 19a, a release device 23 in the form of the slider is provided, through which a pin 30 can engage in the contour 31 and thereby move the entire wedge element 19a in the course of the unlocking process upward (cf. Fig. 5a ). For applying the wedge element 19a for automatic locking, a leg spring 32 is provided, which constantly presses the wedge element 19a in the direction of the wedge position. The conclusion forms a holding plate 29 with an opening 33, passes through a screwdriver in a first depth position to the toothing of the release device 23 and in a second depth position to the adjustment of the tilt adjustment 24. The inclination adjustment device 24 with its adjusting wheel is brought about via an actively connected toothing 34 - which is arranged on the lever 25a - via the movement-coupled lever 25a, 25c.

Fig. 7a shows a vertical section through the fitting 10 during the unlocking process, Fig. 7b shows an enlarged detail view this. Through the opening 33 ( Fig. 6 ) of the holding plate 29, a screwdriver 35 is introduced, wherein the release device 23 in the form of the slider, the wedge element 15a moves from the locked position. According to Fig. 7b It can be seen that the screwdriver 35 occupies a first depth position X normal to the longitudinal direction Zargen. If the release device 23 is rotated in its uppermost end position, the screwdriver is now in a staggered depth position Y introduced ( Fig. 8a, 8b ), in which the adjusting wheel of the inclination adjustment device 24 can be actuated. If the screwdriver is completely pulled out after adjustment, the release device 23 moves to its lowest end position and the wedge element 15a is automatically locked again by spring force.

Fig. 9 shows an alternative embodiment of the invention. The fitting part 10 for the front panel 6 has two mutually connectable and preferably mutually adjustable parts 10a, 10b. At the part 10a store the dowels 11 for the attachment of the front panel 6. On part 10b known in the prior art Seitenverstelleinrichtung 17 for adjusting the front panel 6 is arranged. The parts 10a, 10b are pivotable about an inclination adjustment device 24 with each other connected. The drawer frame 4 associated fastening device 9 comprises again acted upon by a spring 18 catch part 15. The locking device 19 has a wedge element 19a, which is pivotally connected to the catch part 15 via the rotation axis M. The wedge element 19a has a guideway 21 - in the present case a slotted guide -, wherein the clamping element 19a can rotate about the stationary stop 20 along this guideway 21. In Fig. 9 the ready position of the catch part 15 is shown, in which it is automatically latched to the holding part 14 of the fitting part 10.

Fig. 10 shows the moment shortly before the catch between catch part 15 and the holding part 14. The spring 18 acted on the wedge member 19a the catch part 15 so that when triggered both the catch member 15 in its locking position and the wedge member 19a can be pressed into its locking position.

Fig. 11 now shows the fully latched and beyond locked position of the catch member 15. By the insertion movement of the holding member 14 of the catch member 15 has been moved counterclockwise and locked. In addition, there was a synchronous locking of the catch member 15 by the wedge member 19a was also pivoted counterclockwise. It can be seen that the fixed stop 20 compared to Fig. 10 located at the opposite end of the guideway 21. The catching member 15 is thus firmly locked by the wedge member 19 a between the pivot point M and the fixed stop 20. To release the locking of the catching member 15 and the locking device 19 with the wedge member 19a only needs a screwdriver attached to the receptacle 16 and rotated clockwise.

Fig. 12a shows a vertical section through the fitting part 10 according to the embodiment of the Fig. 9 to 11 , The connectable to the fastening device 9 of the drawer 4 part 10b has a tilt adjustment 24, wherein by operating a screwdriver a the front panel side portion 10b associated Neigungsverstellplatte 36 relative to the part 10b is adjustable. The tilt adjustment plate 36 has arcuate slots 37a, 37b which are movable relative to the stationary bolts 38a, 38b. Thus, if the toothing of the inclination adjustment device 24 is moved upward by rotational movement of a screwdriver, then the front-panel-side part 10a of the fitting part 10 takes due to the curved slots 37a, 37b a part 10b inclined position. This situation is in Fig. 11b shown. It can be seen here that the bolts 38a, 38b are located at the lower edge of the curved elongated holes 37a, 37b. Similarly, the fitting 10a - starting from the position according to Fig. 12a - Be tipped away by opposite rotational movement of the part 10b.

Fig. 13 shows a perspective view of the fitting part 10 with its two parts 10a, 10b, wherein the part 10b via its holding part 14 with the fastening device 9 releasably connectable or beyond also also be locked. This figure shows the locking device 19 with the wedge element 19a in the first operating position, in which the catching part 15 is firmly locked via the rotation axis M and the wedge element 19a supported on the stop 20.
