Connection between a drawer and a

Drawer guide rail

The subject of the innovation is a new type of connection between a drawer and a drawer guide rail.

So far, it is only known to attach an associated guide rail to the underside of a drawer, e.g. the floor.

As a rule, the drawer-side guide rail was integrally connected to the drawer frame.

It is also known to attach such drawer guide rails to a side wall of a drawer or to a frame by screwing them on.

If you wanted to remove the drawer from the body, the drawer had to be unhooked from the body together with the drawer-side guide rail attached to it.

However, this creates problems when unhooking because the protruding guide rails pose a risk of

► 9 · *

There is damage to the body when removing or reinserting the drawer.

A further disadvantage of the state of the art is that the drawer has a higher weight due to the guide rails attached to it and is therefore relatively difficult to remove from the body.

The innovation is therefore based on the task of developing a connection between the drawer and the drawer-side guide rails in such a way that this connection is detachable.

To solve the problem posed, the innovation is characterized by the technical teaching of claim 1.

The key feature of this innovation is that a locking connection is provided between the drawer-side guide rail and the drawer itself.

It is preferred if the locking connection is designed as a locking spring connection in the front area of the 5 drawer-side guide rail.

In this case, it is provided that the aforementioned locking connection is arranged on one part, e.g. the drawer, which works together with an associated locking recess in the other part, e.g. the guide rail.

Of course, the kinematic reversal according to the present innovation is also included in the innovation, namely that the locking part on the guide

rail and the corresponding recess is arranged on the drawer.

In all embodiments, it is preferred if the rear side of the drawer-side guide rail is connected to the drawer using a standard slide-in fastening.

The aforementioned locking connection in the front area between the underside of the drawer and the associated front side of the drawer-side guide rail can be released using several different embodiments. It is preferred here if a spring-loaded locking lever is provided, which spring-loadedly engages with a corresponding locking head in the associated locking recess on the guide rail.

An additional spring clip can be present here, which facilitates the insertion of this locking arrangement into the 0 drawer-side guide rail and which, when mounted, exerts an additional holding-down force on the locking head in the locking recess in the drawer-side guide rail.

There are different designs for the type of locking head (latch locking or head locking).

Likewise, the type of locking recess can be adapted to the corresponding locking spring.

The subject matter of the present innovation arises not only from the subject matter of the individual protection claims, but also from the combination of the individual protection claims with one another.

All information contained in the documents, including the summary,

The information and features disclosed, in particular the spatial configuration shown in the drawings, are claimed as essential to the invention insofar as they are new individually or in combination compared to the prior art.

The innovation is explained in more detail below using drawings showing several implementation options. The drawings and their descriptions reveal further key features and advantages of the innovation.

7 to 10 : Another embodiment of the connection.

In a first embodiment according to Figures 1 and 2, the locking connector 2 between drawer 3 and guide rail 1 essentially consists of a profile with a spring clip 8 and a locking head 6.

The snap connector 2 is preferably located in the front area of the drawer and can be attached to the front panel 4 and/or the drawer base 5.

In order to attach the drawer 3 to the drawer guide rail 1 for the first time, when the drawer 3 is first pushed into the guide rail

1 so that the spring clip 8 slides within the rail 1 and the locking head 6 of the connector

2 engages in the corresponding recess 7 of the guide rail 1, as shown in Figure 2.

When locked, the spring clip 8 exerts a counterforce on the locking head 6, so that a stable connection is created.

At the rear end of the guide rail 1 there is a stop 10, which also acts as a tilt protection. This ensures a secure connection of the drawer

3 with the guide rail 1 in the rear area of the drawer.

Figures 3 and 4 show a similar embodiment to the previous figures, whereby the connector 2 has a locking head 6 attached to the spring clip 8.

When the drawer is pushed in, the locking head 6 snaps upwards into the corresponding locking recess 7 in the guide rail 1.

Figures 5 and 6 show a locking connection 2, which has a spring clip 8 and a locking pin 12 attached to it. The guide rail 1 preferably has a corresponding recess 11 on its upper side, into which the locking pin engages when the drawer 3 is pushed open.

In the above-mentioned embodiments, the

Locking process in vertical direction, e.g. from bottom to top.

In the embodiment according to Figures 7 to 12, the locking process takes place in the horizontal direction.

As can be seen from Figures 7 and 8, the guide rail 1 has a bent portion 13 on its side facing the middle of the drawer. The connector has a locking hook 14 attached to the spring clip 8. When the drawer 3 is pushed in, the locking hook 14 engages in the bent portion 13.

An additional guide bracket 16 ensures that the drawer 3 is safely guided in the guide rail 1 during the locking process and fixes the drawer 3 together with the locking connector 2 in the guide rail 1, compare Figure 9 and

0 By manually operating the respective spring clip 8 of the locking connector 2, the connection between drawer 3 and guide rail 1 can be easily released, which is a significant advantage of the innovation.
