Description

Adapter device for a drawer

The invention relates to an adapter device which has a support leg for supporting a drawer bottom.

It is known to provide for the connection of at least one Zargenelements with a drawer bottom one or more metallic adapter devices. These adapter devices are mounted on the Zargenelement and have a support leg, which is provided with fastening claws for the attachment of the drawer bottom. The

Adapter devices can - according to the prior art, but also according to the invention - alternatively even an integral part of the

Zargenelementes be and serve to connect to the

Drawer base.

In EP 1 513 429 B1 a connecting component with a contact web and a support leg for the drawer bottom is described as an adapter device, wherein its support leg of two to each other

offset in height leg sections consists. In the assembly position, the underside of the drawer bottom abuts against the outer support leg section, which is farther in relation to the contact web. In the transition region between the two leg portions an elongated narrow punched-out is provided, wherein at the edge of this punching two adjacent parallel mounting claws upwards in the direction of the to be mounted

Drawer bottom protrude. These fastening claws are made of the originally located in the punching area material of the

Punched component and thus form an integral part of the support leg. In the area of their free ends are the

Fixing claws each beveled in opposite directions so that they taper to a point. During assembly, they are in positive engagement with the

Bottom of the drawer bottom pressed.

Since the fastening claws are relatively sharp-edged and protrude from the surface of the support legs, there is improper Handling the risk that damage during assembly

Floor slabs occur. Furthermore, the strength of the connection of the fastening claws to the drawer should be increased.

From DE 93 03 903 a drawer with a drawer frame and a drawer bottom is known. The drawer frame is with a

Provided adapter device with a support leg, are worked out of the cloth, which are provided with claws. The claws are paired with two prongs, which spread apart when pressed into the drawer bottom and barb-like anchor in the material of the drawer bottom. The lobe is horizontal

Slits that are open on one side, formed in the support leg. Again, the claws are relatively sharp.

In EP 0 888 737 A1 a drawer frame is described, which is associated with an adapter device having a horizontal support leg. From the horizontal support leg several lobes are punched out with an upwardly directed claw. The claw is here in each case arranged on the side of the cloth and has a bent edge. The flaps are aligned in the longitudinal direction of the support web. Since here too, the flap and the claw are very sharp-edged, a high risk of injury is given. In addition, the furniture parts scratch very easily during assembly. In addition, they bend laterally on the cloth

arranged claws when driving into the bottom plate at its crease edge often, so that a secure attachment of the bottom plate is not always guaranteed. The invention is therefore based on the object, the adapter device of the generic type so that a secure fixation of the drawer bottom can be secured to the associated drawer frame, in which in particular the risk of scratching furniture parts is further minimized. In addition, the invention is concerned with the task of simplifying the installation of a drawer. This object is solved by the subject matter of claim 1.

Due to this design of the fastening claws is the risk of

Scratching the bottom plate during assembly decreases and the

Risk of injury significantly reduced. A preferred convex back contour of the fastening claw ensures before pressing into the ground that sharp edges, which may also be provided with cutting burrs, do not touch the surfaces on which the adapter comes to rest.

After pressing is preferably and advantageously the back contour does not protrude beyond the bottom of the support leg.

To avoid damage to the drawer bottom is

Preferably and advantageously a cup-shaped contour in the direction of

Drawer bottom pulled out of the support leg.

The claw webs are issued from the support leg transversely to the extension direction, preferably and in turn advantageous from the bottom support portion of the cup-shaped contour.

The claw webs are preferably connected to the side of the drawer center edge of the support leg.

When the claws penetrate into the drawer bottom, the displacement of the claw webs causes a displacement movement, which reduces the distance between the end face of the base and the contact web and brings the end face of the bottom against the contact web into abutment. The connection with the edge portion of the support leg allows when reaching the system on the contact web dodging of the edge portion in the direction of the drawer center out, so that even when granting the usual manufacturing tolerances, a plant of the soil is achieved at the plant jetty.

The support leg has in the extension direction in the edge regions hump, which are issued against the direction of the cup-shaped contour. Further advantageous embodiments of the invention can be found in the

Dependent claims.

In addition, the invention is achieved by a drawer with the features of claim 19.

12th

Figures 1 to 15 show an adapter device 1 for the connection of a Zargenelements with a drawer bottom (B, shown), for example in Fig. 5c, d) or for the attachment of a drawer bottom B to a Zargenelement. The adapter device can also be an integral part of the frame element (not shown here).

The one or more Zargenelement (s) forms / each form a side wall of the drawer. One or more adapter devices 1 can be provided for a drawer frame. On a drawer are preferably on two parallel sides of one or more such

Zargenelemente arranged with one or more adapter devices.

The adapter device 1 is preferably made of a metal sheet and has a mounting portion for placing the Zargenelements with a U-shaped cross section with a web wall 2 and two side wall sections 3, 4. The side wall portions 3, 4 are preferably bent from the web wall at an angle such that they are substantially adapted to the inner contour of the Zargenelementes.

The side wall portion 4 is formed such that it is at least partially in the region of the drawer bottom B, wherein here also advantageously the connection regions are arranged with the side of the Zargenelementes lying to the drawer center, then preferably carried out vertically (see Figure 6).

As a result, the side wall of the drawer bottom, which is usually executed perpendicular to the bottom surface B, come close to the inner contour of the Zargenelementes to rest when the drawer bottom when connecting to the adapter device to the Zargenelement or

Zargenelement can be brought to the drawer bottom.

At the lower edge of one side wall section 4, a strip-shaped, at right angles to the side wall portion 4 is bent

Support leg 5, which is designed so that in the area of a support portion 19 on a support surface A, the underside of a bottom plate, not shown here, is placed in the mounting position.

For this purpose, within the support leg 5 of the support portion 19th

formed, which is shaped in the manner of an elongated, rounded in the corner, cup-like elevation of the material of the support leg 5 is formed. Compared with a over the entire length of the support leg extending continuous survey results from the cup-like survey the advantage that a further stiffening of the support leg is also achieved transversely to the longitudinal extent.

The support portion 19 is slightly, preferably 0.3 to 5 mm, over the plane A5 of the support leg 5 (see Fig. 5a) in the direction of

To be placed drawer bottom and forms the support surface A from. Since it has rounded edges and preferably rounded corners, so far the risk of scratching the drawer bottom when placed on the support leg 5 is already reduced. The support portion 19 extends almost over the entire length of the support leg 5 and its entire width and can be particularly advantageously and easily formed by a pressing forming process. The support leg 5 is provided in the region of the support portion 19 with at least one or more, here two windows in the form of punched-out 6, 7, which are formed circumferentially closed. The punched-out 6, 7 are advantageous here in total in the support leg 19 and thus directly adjacent to the support surface A. The cutouts preferably have a substantially T-shape in plan view.

Within the punched-out sections 6, 7, during clipping, claw webs 8 (also called connecting webs) are left, which are oriented transversely or at least essentially transversely to the extension direction Z of the drawer and which face away from the lower edge of the side section 4 (or in the assembled state towards the middle of the drawer)

Edge portion 9 of the support leg 5 in the region of the support portion 19 are connected.

This has the advantage that a drawer bottom when pressing the

Fixing claws to the frame or the adapter device 1 is used by 12 after the penetration of the one, two or more teeth of the fixing claw 1 1 during pivoting of the drawer bottom in the direction of the side wall section 4 or this is moved to the drawer bottom, depending on which the parts to be joined during assembly is fixed (see Figure 5c). The claw webs 8 are compared to the support surface A of the support portion 19 of the strip-shaped support leg 5 bent down and advantageously have an arcuate, convex arched back contour. In order to reinforce the curvature of the claw webs 8, a recess 10, which runs parallel to the edge portion 9, provided within the claw webs 8, so that the claw webs are preferably connected in two areas with the rest of the support leg. Such are the claw webs 8 in itself movable and their claws particularly well in a drawer bottom B (or a bottom plate) can be introduced (see also Fig. 5d).

Due to the arcuate, arched back contour of the claw webs 8, which is clearly visible in Fig. 5, on the one hand, the risk of injury by the

Minimizes claw webs when mounting and it can also be a scratching of furniture surfaces are avoided.

The claw webs 8 extend in a bend on the side facing away from the support surface side of the support section down and go at their ends in a fastening claw 1 1 for engagement in the drawer bottom B, which is oriented perpendicular or nearly perpendicular to the support plane A, but in the As-delivered condition before assembly does not reach all the way to support level A. The claw webs extend from the side facing away from the leg 4 edge of the punched-6, 7 in the direction of the leg 4 in the punched-6, 7 inside. The fastening claw 1 1 has for this purpose preferably one, two or more teeth 12,13.

Preferably, the free ends of the prongs 12, 13 are in the unassembled state before placing the drawer between the plane A5 of the support leg 5 and the plane in which the support surface A is located. This shows a particular advantage of the survey 19, as it offers the possibility to arrange the ends of the claws preferably in the above-defined area.

Particularly preferred is the embodiment with two prongs 12, 13,

in particular such that the opposite sides of the two prongs 12, 13 enclose an obtuse angle α. The outer edges are parallel to each other and perpendicular to the bottom surface, i. the width of the

Mounting claw 1 1 is constant over the area that will penetrate into the drawer bottom prior to insertion, with the outer edges aligned perpendicular to the drawer bottom (see Figures 5b, 5c). The prongs 12, 13 are below the plane of the assembly before assembly

Bearing surface A of the support portion of the support leg 5,

preferably between the levels A and A5.

When penetrating the fastening claws 1 1 in the drawer bottom - for example, in a mounting station with a vertically to the level of the drawer bottom B moving pressure piece D - move the

Fixing claws 1 1 upwards (see Fig. 5c) in the drawer bottom B and it spreader the teeth 12, 13 of the fastening claws 1 1 at the same time to the outside (see Fig. 5d). The angle α between the teeth 12, 13 thus increases when the

Claws 1 1 with their teeth 12, 13 press into the drawer bottom. It comes advantageously to a barb-like fixing the claws 12, 13 in the material of the drawer bottom, by the width

Fastening claw 1 1 increased from the tooth base to the tips (see again Fig. 5d, which shows in dashed lines the position of the fastening claws after penetration into the drawer bottom).

In a second embodiment, which is shown in Figures 1 1 to 15, a crowned or bead-shaped indentation 14 is provided in the claw web 8, which leads to a stiffening of the resulting through the recess 10 bridge 15 in the claw web 8. As a result, the spreading of the teeth 12, 13 can be further supported, since the required tear-out forces are increased.

In order to provide an attachment of the drawer bottom by means of another mounting option, such as a screw, holes 16 are preferably further punched into the support leg 5. This is an additional connection of the

Drawer bottom with the adapter device 1 possible. It may also be provided to provide only this type of connection. Because the

Mounting prongs 12, 13 are arranged below the support surface of the support leg 5, they do not interfere with the assembly by means of a screw connection and also do not scratch the floor. If an adapter device 1 now has its underside on a piece of furniture or another planar surface, then the claw web 8 shown in section in FIGS. 8 and 13 only touches this other flat surface in a point-like manner. As a result, scratches on furniture or other flat surfaces can be effectively prevented. Since the prongs 12, 13 of the fastening claws 1 1 are below the support surface of the support leg 5, there is also no scratching of the bottom plate when it is brought into an assembly position during assembly. Furthermore, the risk of injury is minimized because the prongs 12, 13 below the

Pad surface are arranged.

In order to avoid scratching even when the adapter device 1 is placed obliquely on another flat surface, one or more spherical-segment-like, for example, hemispherical projections 17 are formed on the underside of the support leg 5, which projections are formed, for example, by press-fitting.

Preferably, a plurality, in particular four, of the projections 17 are respectively provided in the corners of the underside of the support leg 5 of the adapter device 1 in regions outside the support section 19. When placed obliquely on another flat surface, it thus always comes only to a punctiform contact of the support leg 5, so that the risk of damage to the other flat surface is low.

After pressing the fixing claws 1 1 in the bottom plate of the claw ridge has been moved to the plane of the support surface A out. However, this plane is spaced from the peripheral edge portion 18 of the support leg 5, which causes the cup-like support portion. Because the humps 17 are formed opposite to the direction of the support surface A from the plane A5 on the underside of the support leg 5, there is a relatively large area by the indented claw webs 8 can be arranged without contact to a flat surface, which is spanned by at least three bumps which are arranged through at one or more ground-mounted adapter devices. This means that relatively large height tolerances within the range described here (of Bottom of the drawer bottom to the height of the humpback) can be admitted when pressing the mounting claws, without touching the indented claw webs, which can lead to scratching, at levels below the hump.

Since the humps 17 are formed in the corners of the support leg 5 and thus in the edge region 18, when a bottom plate connected to the adapter devices 1 is placed on a support or a piece of furniture, it stands on the projections 17, so that it is almost punctiform even in the mounted state Contact points are given.

Since the claw webs 8 of the adapter device 1 are arranged transversely to the extension direction of the drawer, a displacement of the drawer bottom in the extension direction Z when driving in the teeth 12, 13 of the

Fixing claws 1 1 avoided and accurately fitting

guaranteed. In addition, a lever arm is created by the claw webs 8, so that for the driving of the teeth 12, 13 of the

Fixing claws 1 1 in a bottom plate a relatively small force is required. As a result, the assembly is facilitated and allows precise positioning of the adapter device 1 on the bottom plate.
