Description

Connection arrangement for connecting a drawer wall with a

drawer bottom

The present invention relates to a connection arrangement for connecting a drawer wall, in particular a drawer front panel, to a drawer bottom according to the preamble of claim 1. The inventions also relate to a drawer.

A generic connection arrangement is known for example from DE 10 2011 052897 A1. As stated in this publication, the connection arrangement is preferably used to additionally fix a front panel of a drawer to the drawer bottom and to provide additional support for the drawer bottom in order to support the fixing of the front panel to the side frames of the drawer. This connection arrangement has proven itself in practice.

It has been found to be disadvantageous that the assembly of this connection arrangement is relatively complex, since on the one hand the drawer panel is manually pressed onto the drawer bottom for correct fixing and at the same time an assembly element connected to a base part via a flexible tab is used to fix the connection arrangement on the drawer tenboden serves, must be inserted manually into the shaft of the base part in order to screw the mounting element to the drawer bottom.

The object of the present invention is to further develop a connection arrangement of the generic type in such a way that it can be assembled in a simpler manner while at the same time minimizing a gap between the two drawer parts to be connected to one another.

This object is achieved by a connection arrangement having the features of claim 1 and by a drawer having the features of claim 15.

The connection arrangement according to the invention for connecting a drawer wall to a drawer base in such a way that a displacement of the two drawer parts relative to one another along at least a first direction axis is prevented and along at least a second direction axis se is possible to a limited extent, has a base part with a retaining plate and at least one first mounting element for fixing the base part to the drawer wall. A drawer wall can be designed as a rear wall, side wall and/or front panel.

The connection arrangement also has a second mounting element that can be inserted into a shaft in the retaining plate of the base part and that can be fixed to the drawer bottom.

The second mounting element has a through hole for receiving a fixing means, in particular a screw, a dowel pin, a dowel, rivet or the like, with which the second mounting element can be fixed to the drawer bottom.

Opposite, almost parallel or almost parallel to each other aligned shaft walls of the shaft and along these guidable side walls of the second mounting element are inclined at an acute angle or arc aligned to the through hole of the second mounting element.

The inclination of the shaft walls and the side walls of the assembly element makes it possible in a simple manner during assembly, when fixing the second assembly element to the drawer bottom, to automatically attach the drawer wall by inserting the second assembly element into the shaft of the base part fixed to the drawer wall pull the bottom of the drawer in and thus minimize a gap between the two drawer parts in a simple manner.

Advantageous variants of the invention are the subject of claims at under.

According to an advantageous embodiment variant, a width of the shaft extending in the third direction axis is greater than a width of the second assembly element that can be inserted into the shaft.

This allows a later adjustment of the two drawer parts to each other in the second and/or third directional axis. According to an advantageous further development, the shaft and the second mounting element are T-shaped when viewed in a plane perpendicular to the second directional axis.

On the one hand, this enables reliable guidance of the second assembly element in the shaft and, on the other hand, a stable design of the retaining plate of the base part, since material reinforcements are made possible by the T-shaped design of the shaft in particular in the area of the retaining plate.

According to a further advantageous embodiment variant, the second mounting element is fixed to the retaining plate in a state before it is mounted on the drawer base via a connection, in particular at least one web or at least one film skin, in such a way that the second mounting element protrudes at least partially from the shaft.

This enables the second mounting element to be pre-fixed to the retaining plate, preferably above the shaft, and thus eliminates the need for manual positioning of the second mounting element for insertion into the shaft, which makes assembly much easier. For this purpose, the second assembly element can be produced in a one-piece construction with the holding plate and who can be detachably connected to it via at least one film gate.

According to an advantageous development, the connection can be destroyed by an insertion movement of the second mounting element into the shaft.

According to a further embodiment variant of the invention, the at least one first mounting element is designed as a dowel, in particular as a slotted dowel, with ribs or harpoon webs which are arranged at least partially around the outside of the dowel.

This ensures that the base part is reliably fixed to the drawer wall, with screws being screwed into the dowel or pins being pressed in, which spread the harpoon webs open in a bore provided for this purpose in the drawer wall.

According to a further advantageous embodiment, an elastic loading area is formed between the Hal teplatte and the at least one first mounting element. This elastic range has the advantage that assembly is possible even if the drawer parts are misaligned relative to one another, and assembly tolerances can be compensated for, for example in a case in which the gap between the drawer parts is already smaller than the displacement of the drawer base before the second assembly element is placed on the drawer bottom Base part in the direction of the first directional axis when immersing the second Monta geelements in the shaft, so that an undesired bulging or other deformation of the base part is prevented by the elastic area verhin.

An additional advantage is that the elastic area compensates for the total tensioning path that is reached after the fixing means has been fully inserted into the second assembly element but before the second assembly element moves smoothly into the shaft. This total clamping path is also dependent on the adjustment direction of the drawer wall along the second direction axis.

The elastic area preferably has a plurality of reversibly bendable lamellae.

According to a preferred embodiment variant, the crumple area can be stretched reversibly in the direction of the first directional axis, which brings about the advantages mentioned above.

According to a further preferred embodiment, the retaining plate can be bent reversibly around a bending axis parallel to the third directional axis by bending the elastic region such that the retaining plate can be bent from a position in which the second mounting element is lowered into the shaft into a position in which which protrudes the second mounting element completely out of the shaft.

Such flexibility of the elastic area allows the connection between the base part and the second assembly element to be released in a simple manner without the base part or the second assembly element having to be detached from the respective drawer part.

According to a further advantageous embodiment variant, in a surface facing away from a pressure surface of the second mounting element, there is a recess surrounding the through hole to limit the penetration depth. Fe of the fixation means formed, whereby a form-fitting fixation of the second mounting element on the drawer bottom is made possible without the fixation means, for example in the form of a screw or a dowel pin, protruding with its head from the second mounting element.

According to a further advantageous variant embodiment, at least one finger recess is formed on a region of the holding plate which faces away from the first mounting element.

The finger recess is preferably designed as a curved web with ribs formed on this.

Such a finger recess makes it easy to manually pull the drawer wall against the drawer bottom to reduce the gap between them for aligning the base part before fixing the second mounting element to the drawer bottom.

A drawer with a front panel that can be adjusted in height and/or sideways relative to a drawer bottom, in which the drawer bottom is connected to the front panel via a connecting arrangement, is characterized by a connecting arrangement as described above.

Preferred exemplary embodiments of the invention are explained in more detail below with reference to the accompanying drawings.

In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the connection arrangement, base part, first mounting element, second mounting element, shaft, retaining plate and selected in the respective figures the like. These terms are not to be understood in a limiting sense, that is, these references can change due to different working positions or the mirror-symmetrical design or the like.

In FIGS. 1 and 2, the reference numeral 1 designates a variant of a connection arrangement according to the invention.

As shown in Figures 3, 4 and 7, for example, the connection arrangement 1 is used to connect a drawer wall 10, in particular in the form of a drawer front panel, to a drawer bottom 11 in such a way that the two drawer parts can be displaced relative to one another along at least a first directional axis x is prevented and possible to a limited extent along at least one second directional axis z.

The connecting arrangement 1 has a base part 2 with a retaining plate 5 and at least one first mounting element 4 for fixing the base part 2 to the drawer wall 10 . In the embodiment variant shown, two such first mounting elements 4 are provided.

The first mounting elements 4 are designed as dowels, in particular slotted dowels, with slots 41 and with ribs or flare webs 42 which are arranged at least partially around the circumference of the outside of the dowel.

These dowels are inserted into the mounting holes provided for this purpose on the drawer wall 10 and are spread open by the shape of the Flar- punenstege 42, in particular after screwing or pressing in screws or pins, not shown here, through which the respective dowel increases its outer diameter is secured against being pulled out of the mounting holes in the drawer wall 10.

As can also be seen in FIGS. 1 and 2, the retaining plate 5 has a shaft 51 into which a second assembly element 3 can be inserted, which can be fixed to the drawer bottom 11, as is shown in FIGS. 4 and 7, for example.

The second mounting element 3 has a through hole 38 for receiving a fixing means, preferably a screw 9 shown here, with which the second mounting element 3 can be fixed to the drawer bottom 11 . It is also conceivable to provide instead of the screw 9 for fixing a roll pin, Dü bel, rivet or the like.

As further shown in Figures 1 to 4, opposite shaft walls 52, 53 of shaft 51, aligned parallel or almost parallel to one another, and side walls 33, 34 of second mounting element 3, which can be guided along these, are inclined at an acute angle to through hole 38 of the second Mounting element 3 aligned.

It would also be conceivable for the shaft walls 52, 53 and correspondingly also the side walls 33, 34 of the second assembly element 3 to have a curved configuration.

The inclination of the shaft walls 52, 53 and the three side walls 33, 34 of the second mounting element 3 is preferably between 5° and 20°, particularly preferably between 10° and 13°, particularly preferably about 11°.

This inclination or curved design of the shaft walls 52, 53 of the shaft 51 and correspondingly the side walls 33, 34 of the second assembly element 3 have the effect that when the connection arrangement 1 is assembled after the base part 2 has been fixed to the drawer wall 10 via the first assembly elements 4, the im second mounting element 3 pre-assembled screw 9 is attached with its tip to an underside of the drawer bottom 11, as shown in Figure 3.

Then, as shown in Figure 4, the screw 9 is screwed into the drawer bottom 11.

The length of the screw 9 is such that a first part of the threaded neck 92 of the screw 9 can be screwed into the drawer bottom 11 before the second mounting element 3 is drawn into the shaft 51 in the Hal teplatte 5 . This state is shown in FIG.

The second assembly element 3 is then drawn into the shaft 51 in the holding plate 5 of the base part 2 with further tightening of the screw 9 .

Due to the shaft walls 52, 53 of the shaft 51 inclined at an acute angle, corresponding to the side walls 33, 34 of the second assembly element 3, the drawer wall 10, which is designed as a drawer front panel, for example, will move as the second assembly element 3 progressively dips into the shaft 51 to the end face of the drawer bottom 11 together with the base part 2 and thus ensures that a gap between the two drawer parts 10, 11 is minimized without manual force having to be exerted against the drawer wall 10.

So that the second assembly element 3 does not have to be positioned manually in front of the shaft 51 during assembly, according to a preferred embodiment variant the second assembly element 3 is fixed to the retaining plate 5 in a state prior to its assembly on the drawer bottom 11 via at least one web 12 that the second mounting element 3 at least partially protrudes from the shaft 51.

In the exemplary embodiment shown, the base body, referred to here as the dome 31 , is held by the second mounting element 3 completely outside of the shaft 51 of the retaining plate 5 by two webs 12 .

As soon as the dome 31 enters the shaft 51, these webs 12 are destroyed by breaking off the edges of the shaft 51 and the dome 31, respectively.

Figures 5 and 6 show the connection arrangement 1 in the final assembly position without showing the drawer parts 10, 11.

Figure 7 shows the connection arrangement 1 mounted on the two drawer parts 10, 11.

As shown in FIGS. 5 and 6, the second assembly element 3 is pushed into the shaft 51 in the final assembly position. In the final assembly position, a contact surface 35 of the dome 31 is in contact with the bottom 11 of the drawer.

In order to enable a lateral displacement of the drawer parts 10, 11 relative to one another in a direction y after the assembly of the connection arrangement 1 on the two drawer parts 10, 11, as can be seen in FIGS width b5ii, Ö512 of the shaft 51 extending in a third direction axis y is preferably greater than a width b3i, b32 of the second assembly element 3 that can be inserted into the shaft 51.

The second mounting element 3 is to enable stabilization of Hal teplatte 5 as well as the shaft 51 in a plane perpendicular to the second direction T-shaped when viewed along the z axis. The dome 31 with the pressure surface 35 is wider than a tapered section 32 of the second mounting element 3.

The tapered section 32 has a bevel 36 on its side facing away from the pressure surface 35, as shown in FIGS. The dome 31 has on its side facing away from the pressure surface 35 a Kopfauf measure 37 for receiving the screw head 91 of the screw 9 on.

As is further shown in FIGS. 1, 2, 5 and 6, in the preferred embodiment variant shown here, an elastic area 6 is formed on between the holding plate 5 of the base part 2 and the mounting elements 4 .

This elastic area 6 has a plurality of reversibly bendable lamellae 61 , 63 . On the back of the second slats 63 is a recess 62 is formed, which serves to guide the screws that can be screwed into the dowels.

The elastic area 6 is preferably reversibly stretchable in the direction of the first directional axis x and thus enables the base part 2 to yield without unintentional bulging or even breaking of the holding plate 5.

As shown in Figures 8 to 10, the connection arrangement 1 also enables the connection between the base part 2 and the second assembly element 3 to be released after assembly has taken place without detaching the second assembly element 3 and the first assembly element 4 from the respective drawer parts 10, 11 , i.e. removing the drawer panel from the drawer base when using a drawer.

For this purpose, the retaining plate 5 can be reversibly bent by bending the elastic region 6 about a bending axis parallel to the third directional axis y such that the retaining plate 5 can be bent from a position in which the second mounting element 3 is lowered into the shaft 51 into a position in which the second assembly element 3 protrudes completely out of the shaft 51, as shown in FIG.

As soon as the second mounting element 3 protrudes completely from the shaft 51, as shown in FIG. 10, exerting a force F away from the drawer bottom 11 allows the drawer wall 10, here in the form of a drawer front panel, to be pivoted away. In order to enable bending in a simple manner, as shown in FIGS. 2 and 6, a mounting bevel 8 is formed in a region of the retaining plate 5 remote from the first mounting elements, which allows the retaining plate 5 to be gripped from below and a force to be exerted as shown in FIG in direction F, for example using a lever tool or manually.

Referring to FIGS. 11 to 14, a reattachment of the drawer wall 10 to the drawer bottom 11 after disassembly as explained above with reference to FIGS. 8 to 10 is described below.

As shown in FIG. 11 and FIG. 12, the drawer wall 10 can be brought back to the drawer bottom 11 for remounting the drawer wall 10 on the drawer bottom 11 . Due to the mounting bevel of the retaining plate 5 and the bevel 36 on the dome 31, the retaining plate 5 can slide along the bevel 36 and the mounting bevel 8 until the position shown in Fig. 12 is reached, in which the drawer wall 10 is at least almost applied.

Then, by manually applying a force to the finger recesses 7, which are formed in an area of the retaining plate 5 facing away from the first assembly element 4, the retaining plate 5 can be moved farther in the direction of the force effect that the shaft 51 of the retaining plate 5 is again along the Side walls 33, 34 of the mounting element 3 slide with the shaft walls 52, 53 of the shaft 51 into the mounting position shown in FIG.

FIG. 13 again shows in an isometric representation of the base part 2 the direction of force F of the force required to be exerted on the finger recesses 7 of the holding plate 5. The finger recesses 7 are preferably each designed as a curved web 71 and ribs 72 formed thereon.
