The cupboard (1) has a door (2) which is mounted on a stay (6). This is attached to a plate (4) mounted on the top wall (3) of the cupboard.

Description

The present invention relates to a body element, in particular a cabinet, a chest of drawers or the like, with a flap, through which the body element is closable. The term "flap" is to be understood as meaning any closure elements which are pivotably mounted about arbitrary axes, for example about horizontal or vertical axes.

From the FR 2065203 a body element with the features of the preamble of claim 1 is known. The known from this document body member has a flap through which the body member is closable and a support arm which is in one of its end portions with the flap directly in communication and which is pivotally mounted in its other end by means of a hinge.

On the upper side of the body element is pivotally mounted by means of a mounting plate, a gas spring, which is also pivotally connected in its other end with the support arm.

Cabinets are known from the German utility model DE-GM 76 38 682 and DE-GM 78 11 011, which are closed by means of horizontally extending axes pivotally mounted flaps. The flaps are movable so that they are not or only slightly aligned in their folded open position with the cabinet interior, so that the opening of the cabinet is substantially completely released. The mounting plates of the associated fittings are fixed in the prior art cabinets on the inside of the furniture side wall, which has the disadvantage that the limited by the body of the cabinet by the fitting, d. H. the mounting plate and the lever mechanism arranged thereon is restricted. Further, there is a disadvantage in that the prior art furniture fittings are constructed relatively expensive and beyond due to their arrangement on the inside of the cabinet are relatively cumbersome to install.

It is the object of the present invention to provide a cabinet of the type described above with a furniture fitting that is easy to manufacture and assemble and that allows full utilization of the interior of the body element.

This object is achieved by a body element with the features of claim 1. The body element according to the invention, for example a cabinet, a dresser or the like can be closed by a flap. Further, a fitting is provided which has a mounting plate and a support arm directly or indirectly connected in its end region with the flap, wherein the mounting plate is mounted on the outside of a wall of the body element and wherein the support arm is pivotally mounted on the mounting plate. The body member according to the present invention further comprises a support means which exerts a force opposing the closing force in the opened state of the flap, and which is mounted on the same mounting plate as the support arm.

The interior of the body element can be fully utilized because there are no fittings on the inside. The movement of the flap is determined by the support arm connected in one end region to the flap, which is pivotally connected to the mounting plate mounted on the outside of a wall of the body element.

According to the invention, it is provided that the support device, for example a gas spring, is mounted on the same mounting plate as the support arm.

The wall can be formed by the topsoil of the body element. In this case, there is a swing-up flap, which is pivotable by means of the support arm, wherein the support arm is pivoted in the opening and closing movement of the flap in this case about substantially horizontal and parallel to the top bottom extending axes.

According to the invention it is provided that the support arm is in communication with the flap such that a pivoting of the support arm relative to the flap is not possible. By such a firm connection of the support arm, the flap performs a pivoting movement about the axis, which is formed by the articulation of the support arm to the mounting plate.

In a preferred embodiment of the present invention, a cross-sectionally L-shaped strip is provided on the inside of the flap, on whose one substantially parallel to the flap inside leg extending the end portion of the support arm is arranged, and the other leg is arranged such that it in the closed state of Flap cooperates with a damping element arranged on the wall.

The support arm may be bent at right angles in its end region directed towards the flap and be in direct connection with the flap with this end region, preferably screwed to the flap.

According to the present invention it is further provided that the support arm is connected to the flap in a region which projects in the closed state of the flap over the adjacent body wall. If the fitting according to the invention is arranged on the upper side of the upper floor of a piece of furniture, provision can accordingly be made for the flap to project above the upper floor on its upper side and to communicate with the fitting according to the invention or its support arm on its rear side in this projecting area.

In the case of the body element according to the invention, it is further provided that the axis about which the support arm is pivotable is arranged in the region of the wall facing away from the front of the body element.

This may be the rear area of the wall facing away from the front of the carcass element. The preferably rigid system of support arm and flap is moved accordingly to this arranged in the rear region, for example, the top floor pivot axis. The flap can be completely removed in this way from the aligned with the interior of the body member area. The interior of the body element is thus restricted in the open state of the flap neither by the flap itself nor by fittings.

According to the invention, a support device is provided which, in the opened state of the flap, exerts a force opposing the closing force.

The support device can be a piston-cylinder unit, in particular a gas spring, or a telescopic cylinder which can be driven by means of an electric motor. In principle, any other support means, such as an electric motor driven rack and the like can be used.

The support means may be pivotally connected to a mounting plate and to the support arm. According to the invention is in the mounting plate around the same mounting plate on which the support arm is pivotally mounted.

In a preferred embodiment of the present invention, two support arms are provided. These may be part of a frame and communicate with each other in one or both end areas by bracing. In this case, the flap is supported by two support arms, which are part of a frame, so that overall better strength is achieved. In this case, the frame-forming elements, in particular the struts consist of extruded profiles, which can be connected to each other with appropriately adapted connecting parts. Of course, more than two support arms can be provided, which may be necessary in particular for very wide or high flaps.

In order to increase the strength further, it may be provided that a stiffening plate is provided, which is held in grooves of the extruded profile.

The flap-facing strut can be formed by an L-shaped strip according to claim 3. Further, it is possible that the flap facing the brace is formed by a top-view C-shaped bar, which is in communication with the support arms, preferably screwed to them.

In a further embodiment of the invention, a damping element is provided on the wall of the body element, which cooperates with a provided on the support arm projection, such as a tab, at least in the closed position of the flap.

Figure 1 shows a side view of the body element 1, which is closed by a flap 2.

On the upper bottom 3 of the body element 1 are two mounting plates 4, as can be seen from Figure 3. Figure 4 shows the mounting plate 4 in a plan view with a plurality of through holes, which serve to fix the mounting plate 4 on the upper bottom 3 of the body element 1.

The present invention is not limited to mounting on the outside of an upper floor. The fitting according to the invention can, for example, also be arranged on the outside of a lateral wall of the body element, with the flap in this case being able to be moved about essentially vertical pivot axes.

As further apparent from Figures 1 to 3, 5 support arms 6 are pivotally mounted on the mounting plates 4 via pivot axes formed by bolts. Each of the support arms 6 has an adjustable plate 10, which with the support arms 6 is screwed and which carries a pin 9, in the end region of a pivot axis for the gas spring 8 is formed, as can be seen from Figures 1 to 3 and in particular from Figure 8, showing the plate 10 with pin 9 in a partially sectioned view , The plate 10 has holes for receiving screws, by means of which the plate 10 is fixed to the support arm 6.

The gas spring 8 is pivotally mounted on the same mounting plate 4 as the support arm 6 by means of the axis 7 formed by a bolt. Accordingly, with the mounting plate 4 of the support arm 6 by means of the axis 5 and the gas spring 8 by means of the axis 7 pivotally connected. Furthermore, the gas spring 8 is arranged in its other end pivotally on the pin 9 of the plate 10, which is bolted to the support arm 6.

The support arm 6 is screwed with its directed to the flap 2 end portion with an L-shaped bar 11. For this purpose, the connecting element 17 according to FIG 6. This is the threaded hole 21, by means of which the connecting element 17 can be screwed to the support arm 6. The connecting element 17 also has two blind holes, by means of which the screw connection with the strip 11 according to the figures 1 to 3 takes place. Accordingly, this end portion of the support arm 6 is fixed, that is not pivotable with the L-shaped bar 11 and thus also with the flap 2 in connection. The strip 11 is bolted to the flap 2. In its side facing away from the other end region, the connecting element 16 is inserted into the support arm 6, which is also screwed thereto by means of a threaded bore 21. As can be seen from FIG. 5, the connecting element 16 has a blind hole 18, in which the bolt forming the axle 5 is accommodated, which forms the pivot axis 5 of the support arm 6 on the mounting plate 4.

As can be seen from FIG. 3, the above-described fitting is embodied in duplicate on the upper side of the upper bottom 3 of the body element 1. The two support arms 6 are by means of the strut 15 on the side facing away from the flap 2 side and with the L-shaped bar 11 on the flap side facing each other in conjunction, as is apparent from Figure 3. The strut 15 and the support arms 6 have an extruded profile, which is shown in cross section in Figure 7. This has on its left side in Figure 7 side recesses for receiving the connecting elements 16, 17. Further, the groove 20 can be seen, which serves to receive a stiffening plate 19, which is shown in Figure 3. The stiffening plate 19 has the task of increasing the strength of the support arms 6 having frame.

From Figures 1 to 3 also shows that on the support arm 6 of the tab-shaped projection 14 is provided, which cooperates in the closed position with a damping element 13 on the upper side of the upper bottom 3 of the body element 1 and in this way the closing movement of the flap. 2 attenuates. Furthermore, a further damping element 12 is provided in the front region of the upper bottom 3, which cooperates with the leg of the L-shaped strip 11 extending horizontally in the closed flap position.

When opening the flap 2 from the closed position shown in Figure 1 in the pivoted position shown in Figure 2, the support arm 6 is pivoted about the axis 5 in the counterclockwise direction. At the same time, the gas spring 8 is pulled out and slightly pivoted clockwise, as can be seen from Figure 2. The gas spring 8 supports the flap 2 in its open position. If the flap 2 is to be closed, it is pivoted counterclockwise against the force of the gas spring 8 according to FIG. 2, wherein the support arm 6 is likewise pivoted about the axis 5 in the clockwise direction and the gas spring 8 about the axis 7 in the counterclockwise direction. Due to the fixed, non-pivotal fixing of the support arm on the flap 2, a relatively simple kinematics and a relatively simple construction of the fitting is possible. The flap 2 performs due to their fixed connection to the support arm 6 a pivoting movement about the axis 5, which forms the articulation of the support arm 6 on the mounting plate 4.

Figures 9 to 16 show a not embraced by the invention embodiment of a body element.

Figure 9 shows an embodiment in which the fitting moves by an electric motor 22 with an extendable telescopic cylinder 23. The telescopic cylinder 23 is pivotally connected in one of its end regions with the mounting plate 24, as can be seen for example from Figures 9 to 11. In its other end region of the telescopic cylinder 23 is pivotally connected to the lever 26, which is shown in Figures 13, 13 a and 14. The lever 26 is rotationally connected via a staggered disc 27 with the support arm 25 in connection, which is shown in detail in Figure 12. The lever 26 is connected by means of the slots 28 by a threaded connection with the threaded holes 29 of the support arm 25, wherein the lever 26 relative to the support arm 25 is angularly adjustable in order to adjust motors 22 arranged on both sides. About the lever 26 of the telescopic cylinder 23 is indirectly pivotally connected to the support arm 25 in connection.

The support arm 25 is pivotally connected in one end region with the axis 34 formed by a pin. This is located on the mounting plate 39, which is shown in Figure 15 and in Figure 11 and which is arranged in the rear region of the upper bottom 3 of the body element 1. In its other end region, the support arm 25 has a right angle bent portion 30, by means of which the support arm 25 is screwed to the flap 2.

Also in this embodiment, two of said fittings are provided on the top floor 3 of the body member 1. These are connected to one another by means of the bracket 31, which is C-shaped in plan view, and via the strut 33 designed as a rod. The C-shaped strip 31 serves to stiffen the device. It is supported, as shown in FIG. 11, on the rear side of the flap 2.

As can be seen from FIG. 13a, the lever 26 has a bore 32 with a recess. In this Aufnehmung a corresponding approach of the strut 33 forming rod is inserted, so that the rod by means of positive locking rotationally fixed in the bore 32 of the lever 26 is added. The rod 33 is used not only to stiffen the entire construction, but also to realize a synchronous rotational movement on both sides of the flap 2.

Finally, FIG. 16 shows the mounting plate 24, on which the end area of the telescopic cylinder 23 of the electric motor 22 is pivotably mounted by means of a bolt. Also, the mounting plate 24 is mounted as shown in Figure 11 on the outside of the topsoil 3.

The two mounting plates 24 and 39 are designed in the present embodiment as two separate plates. Of course, the use of a common mounting plate is conceivable.

To open the flap 2, the electric motor 22 is actuated and the telescopic cylinder 23 extended. In this case, the lever 26 is pivoted from its position shown in Fig. 9 counterclockwise, as can be seen from a comparison of Figures 9 and 10. Due to the rotationally fixed connection of the lever 26 with the support arm 25, the support arm 25 and the thus firmly connected flap 2 undergoes a pivoting movement counterclockwise. The flap is moved away according to Figure 10 from the opening portion of the body element 1, whereby the interior is completely accessible. During the opening movement of the telescopic cylinder 23 undergoes a pivoting movement about the provided on the mounting plate 24 pivot axis in a clockwise direction.

In the open position, the extended telescopic cylinder 23 supports the flap 2. During the closing movement, the aforementioned process takes place in the reverse direction until the flap 2 assumes its closed position shown in FIG. 9.

As can be seen from the drawings showing the exemplary embodiments, all pivot axes extend parallel to the wall on which the mounting plate (s) are arranged. In the embodiments, this wall is formed by the upper bottom of the body element. Alternatively, every other comes Wall of the body element for mounting the fitting according to the invention into consideration.

The body element according to the invention has the advantage that no fittings are present on the inside of the body element, so that the interior can be fully utilized both in the closed and in the open position of the flap. The fitting parts are all mounted in the dargestellen in the drawing embodiment on the top of the topsoil, which also allows a relatively simple assembly can be realized. Due to the rigid connection in the illustrated embodiments of the support arms with the flap, the flap undergoes a pivotal movement about the pivot axis of the support arm on the mounting plate. The desired movement of the flap can be realized by a relatively simple construction of the fitting, which is easy to produce.
