Description

"Connecting device and drawer

Association

State of the art:

Drawers or extracts of furniture are usually assembled from individual elements. Come for this

Various types of connection are used.

In wood drawers, for example, the wall elements can be interconnected by simple adhesive or pin connections.

Wall elements of drawers can also over others

especially releasable connection arrangements miteinande be connected, for example by locking.

Object and advantages of the invention:

The object of the present invention is to provide a technically intelligent and economically advantageous type of connection for drawer elements.

This object is solved by the independent claims.

In the dependent claims advantageous variants of the invention are shown.

The invention relates to a device for connecting wall elements of a drawer, wherein a latching connection can be formed and the wall elements in the connected state at least form part of a drawer wall of the drawer and wherein the drawer wall is a front wall, a rear wall

CONFIRMATION COPY and / or at least one side wall. One

Drawer bottom forms as another connected

Drawer element a lower end of the drawer. The latching connection can be set up or released again in particular without tools.

The essence of the invention is that a

Connecting element is provided with bendable locking portions for the formation of the latching connection, wherein the

Connecting element is designed as a separate component such that the connecting element is anchored to an end face and on a surface side of one of the wall elements to be connected. Thus, the connecting element for the connection of two wall elements to one of the wall elements to be connected z. B. anchored to the front, and there remain fixed in position. Subsequently, for the

Completion of the connection of the wall elements that

Connecting element on the surface side of the other

Wall element also be anchored. The

Connecting element is designed or on the

Matched wall elements, that also can proceed exactly the other way, so the connecting element is first fixed to a surface side of a wall element and

is then anchored to the front side of the other wall element. The connecting element and the wall elements are particularly coordinated so that the

Anchoring on both wall elements is realized in each case by a releasable latching connection. The specific design of the latching connection with a connecting element can be the same or different for both wall elements to be connected. Preferably, a connecting element is designed such that it can form a type of latching connection with a wall element, which differs from the type of latching connection, which can form the connecting element with the other wall element. However, it is advantageous that it is optionally possible, first the locking connection with the

Front side of a wall element and then with the

Establish surface side of the other wall element or vice versa. An end face of a wall element is a narrow side at a z. B. plate-like wall element which extends over a wall thickness and forms an outer surface whose

Longitudinal extent in the functional state of the drawer vertically

runs. An end face of the wall element results, for example, by a section through a plate-like

Preproduct of the, wall element, wherein the section extends in the direction of a material thickness of the wall element. Between two opposite end faces further two opposite longitudinal narrow sides extend. A first surface side of a wall element forms the predominant outer surface of the wall element and is separated from an opposite second surface side, which forms a further outer surface, by the thickness of the wall element or the four narrow sides. A cuboid wall element with rectangular surface sides accordingly has two opposite surface sides, two opposite longitudinal narrow sides and two opposite end sides.

With the connecting element can be flexible and in a few

Steps of the assembly of wall elements of a

Drawer done. Especially without tools or by hand. In particular, with a single embodiment of the

Connection element, so to speak universally all the connections that are necessary for the assembly of the drawer from the wall elements can be realized. The same applies to the formed on the wall elements engaging portions, which are necessary so that the connecting element can be latched positionally correct position on the wall elements. This uniform or

Reduced connection system facilitates assembly and minimizes drawer costs or assembly.

With the particular spring-like or elastically bendable latching sections a latching force is permanently provided in the connection area. The bendable latching sections allow an automatic setting of the latching connection at corresponding opposite sections of the wall elements. Under

Applying a counterforce to the effective one Spring force of the locking portions in the connection state, a locking connection can be easily solved again, the

Rastabschnitte in one direction against the direction when setting the locking connection rebound.

It is further proposed that the connecting element

is designed to establish the latching connection of the wall elements in a region in which abuts the end face of the wall element on the surface side of the other wall element blunt. Thus, in the connected state, the connecting element does not appear or remains hidden. A to the actual wall elements additional or attached intermediate element that forms a portion of the visible parts of the drawer wall or complements the wall elements in the assembled state, is advantageously not necessary. A drawer with a corner area with blunt abutting areas can, for. B. also be advantageous in design aspects.

With the connecting element according to the invention can also advantageously a positionally correct orientation of the two wall elements are set up in the assembled state. Because the connecting element is so on the two

Wall elements attachable to that with the latched

Connecting element through the relevant end face and the relevant surface side in the assembled state, only a predetermined relative position is possible and the face and the face side lie flat or possibly almost in positive engagement with each other. This also allows a high supporting effect, wherein the end face over almost its entire surface in contact with a corresponding part of the surface of the surface side. This increases the stability of the drawer.

For a flexible choice of which to connect

Wall elements frontally and which is connected on the surface side, it can be advantageously arranged that on a wall element both the front side and the surface prepared sections are present, where the

Locking element is latched. Preferably, the connecting element is designed to connect the wall elements to be connected in a region which in the connected state of the wall elements a

Corner of the drawer forms. In the corner are the

Wall elements adjacent anyway. With the corner region is usually a separation point of the wall elements available, especially in plate-shaped wall elements, what

is advantageous, so that in the corner area and forces between the wall elements must be transmitted. At the im

Corner region forcibly existing weak point, the connecting element can effectively stabilizing effect.

It is also advantageous that the connecting element is designed such that the latching connection by snapping at least one latching portion in a matched to the latching portion receiving portion of a

Form wall element. In this case, the at least one latching section snaps against a wall element, wherein at least one further latching section can snap with a receiving section on the other wall element to be connected. In each case exactly two latching sections are preferred for snapping to receiving sections of each of the two

Wall elements provided, that is on a connecting element a total of four locking sections, for the two wall elements.

With a snap mechanism, a locking connection can be set up very easily and reliably and

possibly be solved again. In addition, a latching or Einschnappkraft or connecting force on the established locking connection without further predetermined in a detent mechanism formed as a snap mechanism. The

Connection or latching force can be influenced or specified depending on the material, the shape and / or the dimension of the latching sections.

Advantageously, it is acoustically perceptible when the at least one latching section snaps in the correct position, so that a mechanic receives feedback, whether the Locking connection is properly and completely set up.

Advantageously, the connecting element is configured to selectively connect a front or rear wall with a side wall. This makes it extremely flexible

Use a connection element for assembling all wall elements of a drawer. It is only necessary to ensure that for a connecting element suitably prepared receiving portions are provided on the corresponding wall elements, ie on the front, side or rear wall.

It is further proposed that the connecting element

is designed to selectively connect a right or left side existing side wall with a front or rear wall. This also increases flexible use of the

Connecting element for corresponding drawers.

It is particularly advantageous if, for all connections of the wall elements, such connection elements can be used, which are all designed identically.

According to an advantageous modification of

Subject of the invention, the connecting element has at least two mutually effective latching portions for each of the wall elements to be connected. With in particular exactly two mutually effective latching sections for connection to one of the two wall elements to be connected, a mechanically stable and still simple

Formation of the connection arrangement can be realized. For a high stability of the connection with the connecting element, both wall elements to be connected to one another are in each case at least two separate from one another

Supplied latching sections. In addition, in case of failure of at least two separate latching sections, the function of the connecting element at least partially retained by the at least one further latching section remains effective.

In addition, a serving for latching area, in which the connecting element in contact with the corresponding

Wall elements is positioned over two separately effective latching sections or at the edge of the connecting element

Rastabschnitten be selected larger, which further increases the stability of the connection.

Preferably, a latching portion is formed to pass through in the latched state through an opening in the surface side in order with a recess located behind the opening the

Set up latching. With the latching and thereby effective latching force portions of the connecting element, so to speak to the wall element or the surface side

be used, which stabilizes the connection. With the locking can possibly also a distortion of the

Connecting element can be achieved.

The recess is an advantageous embodiment of the matched to the locking portion receiving portion. A recess may, for. B. include an opening and / or a depression. With the opening in the surface side and the recess located farther in or inside the wall element, a particularly compact connection arrangement is realized. In addition, can be latched next to the recess in the recess

Locking portion cooperate further portions of the connecting element and the wall element and thereby increase the connection stability. For example, by adding sections of

Connecting element, which do not engage in the interior of the wall element, come to abutment against the outside of the surface side of the wall element to the plant, for example, to

Support areas, which are at the opening in the

Connect surface side. With the latching a correct position of the connecting element is achieved, which is an exact positioning of the wall elements to each other in the

Connected state guaranteed. In particular, the two wall elements can be connected to one another in a stable manner only when the latching section engages in the recess at the correct position. Overall, with the proposed arrangement, a non-tilting or bending-stable and stiffening connection of the wall element can be established. It is furthermore advantageous that the connecting element has anchoring sections which can be spread apart relative to one another and which, by spreading open by means of a movable adjusting part, develop a clamping effect for the connection of the wall elements to be connected. With such

Arrangement can be realized in a confined space very stable and reliable latching connection via the connecting element. It is particularly advantageous if two

Anchoring sections are each provided with a pair of expandable abutment jaws, with a pair of abutment jaws being engageable by the adjustment member from a neutral position into a detent position expandable by a spread angle. The adjustment can do this between the spreader jaws

pushed or screwed and thereby clamped in the end position between the crowded apart

Fixed jaws be fixed. The expandable

Anchoring sections are advantageously formed in the connection state in openings or recesses of the

Surface side of one of the wall elements to be connected

lock or jam. The recess can

advantageously by a cross-sectionally U-shaped

Groove be formed in the wall element. In the connection state, further sections of the connecting element in the

Locked front side of the other wall element or otherwise fixed.

It is further proposed that the connecting element is configured, a connection with the front side of the

To realize wall element via a Spreizdübelanordnung. An advantageous embodiment with expandable

Anchoring sections is for example a so-called expansion dowel arrangement. About a Spreizdübelanordnung can be set up in a confined space a strong locking.

It is further proposed that the connecting element

Includes hook means with which by clawing in one

Wall element a non-destructively releasable latching connection between the connecting element and the relevant Wall element can be formed. Thus, the connecting element can be anchored particularly stable and durable on a wall element.

It is also advantageous that the connecting element has a dimension, so that in the connecting state portions of the connecting element at least substantially fill a free inner region between two outer sides of the wall element to be connected. The connecting element can be accommodated in an internal space between opposite outer sides of the wall elements to be connected.

It is particularly advantageous that a plug-on part on

Connecting element is present, wherein the plug-on part

Barb having means with the Aufsteckteil

provided hooked connection element to a wall element. Thus, a connecting element can be provided with a barb means for a particularly stable fixation on a wall element.

The barbs are in particular additional or

as an alternative to the latching sections on the connecting element available.

Advantageously, the connecting element for a

Connection formed by consisting of profile material wall elements. With the connecting elements in particular profiled wall elements, with respect to the

Choice of material, a low weight or to save material are advantageous to be used. Preferred are the

Fasteners matched exactly to corresponding receiving sections of the wall elements.

The invention also relates to a drawer with a

Drawer wall of interconnected wall elements, wherein the drawer wall has a front wall, a rear wall

and / or at least one side wall. According to the invention, one of the above-mentioned devices is present on the drawer. This is how the above advantages can be added realize a drawer.

Preferably, the wall elements are connected to each other by butting an end face of a wall element

Surface side of an adjacent wall element connected.

In particular, a rear wall with its front side or with its two end faces abut flush on an inner surface side of side walls of the drawer. In this case forms a surface side of the rear wall or the front wall

respective end faces of the side elements a rear or front narrow side of the drawer.
