Description

The invention relates to a flap holder according to the preamble of claim 1 and a piece of furniture.

In the field of furniture flap holders are known in various designs. A furniture flap is for opening and closing e.g. a storage compartment of a piece of furniture about a preferably horizontal pivot axis upwards or downwards pivotable at e.g. attached to a furniture body. In a downwardly pivotable flap of the flap holder is usually provided for limiting a pivot angle for opening the flap. In this regard, the flap holder may be designed to stabilize a horizontal position of the flap, whereby a surface of the flap, e.g. Shelf or e.g. Use writing pad.

The invention has for its object to provide a valve holder, which can be mounted in a comparatively space-saving.

The object is achieved by a flap holder with the features of claim 1.

Preferred and advantageous embodiments of the invention are specified in the dependent claims.

The invention is based on a flap holder for a vertically pivotable arranged on a furniture body flap, which can be opened by pivoting down. It is the Valve holder for transferring and holding the flap provided and formed in a closed position by means of spring force. The flap holder is equipped with a flap-side arm part which is pivotally connected to the flap about a hinge axis, and equipped with a body-side arm part which is pivotally connected about a pivot axis with a fitting to be fastened to the furniture body. In this case, the arm parts are pivotally connected to each other about a hinge axis, so that an articulated arm arrangement is formed. Furthermore, the flap holder is provided with a first effective between the body side arm part and the flap side arm control means which includes a pressure piece and a control cam, which are held by a spring device against each other, so exerted by the flap holder dependent on the pivot angle of the flap force on the flap becomes. In addition, the flap holder is equipped with a second control device which is effective between the body-side arm part and the furniture body to be attached to the fitting part. The second control device is equipped with a pressure piece and a control cam, which are held by a spring device against each other. In this case, the two spring devices are independent of one another, so that a force exerted by the flap holder on the flap force is composed of two respectively occurring on one of the control force components.

The essence of the invention is that on at least one of the two control devices, a control cam is formed, on which the pressure piece is arranged in a stretched arrangement of the arm parts at a greater distance from the hinge axis than in a kinked arrangement.

In the extended arrangement, the hinge axis between the two arm parts, wherein the arm parts in the extended arrangement can extend each other, for example, rectilinear, in particular to achieve a maximum length. In this case, the stretched arrangement can be advantageously provided with a maximum connection length of the two arm parts for holding a flap in a horizontal position, the flap only by can leave a closing movement.

In a kinked arrangement, the arm parts form an angle between 0 ° and less than 180 °. The flap holder according to the invention has the advantage that at least one of the two control devices opposes the movement of the flap during a downward pivoting opening movement and stores the energy released during pivoting down of the flap in the spring device of the respective control device, whereby it can be provided to support a closing movement. On a piece of furniture with a flap holder according to the invention, opening movements of the flap are thus advantageously slowed by counterforces of the springs and closing movements of the flap are facilitated.

An advantageous embodiment of the invention is that the control cams of both control devices are designed such that in a stretched arrangement of the arm parts, the pressure piece of the first control device in a greater first distance from the hinge axis and the pressure piece of the second control device in a larger second distance the pivot axis are arranged as in a kinked arrangement of the arm parts. This offers the advantage that the released potential energy when swinging down a flap and the associated voltage can be distributed to two control devices with their spring devices. In this way it is also possible to avoid that the two control devices interfere with each other in their effect and possibly cancel each other out.

The pressure piece of one or both control devices may be integrally formed. In this case, the pressure piece may be formed as a sliding body, which is provided in particular for frictional sliding movements along the control cam. As a result, a flap can be continuously preserved in different open positions and in eg a closed position. Furthermore, the pressure piece of one or both Control means may be formed as a rolling element to facilitate opening and closing movements. In this case, the pressure piece preferably comprises a rotary bearing element on which the rolling element is mounted comparatively low friction rotatable and with the particular direct contact of the rolling element with the pressing spring is advantageously avoidable.

Furthermore, it is preferred that a closed position is predetermined, in which the arm parts are arranged at an acute angle to the hinge axis, wherein the flap holder can advantageously provide a force for holding the closed position. The closed position can e.g. be formed by a stop contour on one of the control cam, the e.g. trough-shaped or e.g. can be shaped step-like. Preferably, the arm parts are arranged in parallel side by side in the predetermined closed position, whereby the flap holder requires comparatively little space and space for movement when the furniture flap is closed.

If the arm parts are arranged corresponding to the predetermined closed position, the pressure piece is preferably located at least at one of the control devices at a minimum distance from the joint axis and / or the pivot axis.

The arm parts may have a matching length to allow a relatively favorable power distribution in the open state.

On at least one of the control devices, the corresponding control cam may have a threshold at an open position at which the corresponding pressure piece of the control device is in an open position of the flap. As a result, an unintentional closing of the flap can be difficult or completely prevented. The threshold can be designed both as a survey, for example, in front of the open position or as a trough-shaped depression, for example, at the open position. So that the pressure piece at the open position comparatively stable, the threshold is at least partially adapted to a contour portion of the pressure piece, with which the pressure piece touches the control cam. Optionally, an actuating element - for example on the pressure piece itself - provided, with which the pressure piece can be released from the open position and remove. In order to support a plurality of different open positions of the flap, a plurality of thresholds may be formed on the control curve of one or both control devices.

The invention will be explained in more detail using an exemplary embodiment and described with the aid of the drawings. The embodiment is shown schematically and not to scale in the drawings.

FIG. 1

a schematic side view of a piece of furniture with a flap holder according to the invention,

FIG. 2

a schematic side view of the furniture with the flap holder with the flap closed.

The Figures 1 and 2 show an embodiment of a flap holder 1 according to the invention, with which movements of a furniture flap 3 on a furniture 2 can be influenced. With the furniture flap 3, for example, a storage compartment of the furniture 2 can be closed, which is bounded by a side wall 4b and an intermediate bottom 4c.

The furniture flap 3 is pivotally mounted with a hinge 4d, eg a furniture hinge, on the furniture body 4, in particular on the intermediate bottom 4c, whereby it can be swiveled up and down in a vertical direction. In FIG. 1 is the furniture flap 3 in a horizontally open position and in FIG. 2 shown in a vertical closed position on the furniture 2. The flap holder 1 exerts a pulling force on the furniture flap 3 in both positions.

The flap holder 1 comprises two rod-shaped arm parts 7 and 8. In this case, each of the arm parts 7 and 8 in a longitudinal direction in each case an end region 7a and 8a on which the arm parts 7 and 8 are interconnected by a common pivot joint 9. With the rotary joint 9, a joint axis is predetermined, which is preferably arranged at right angles to the longitudinal axes of both arm parts 7 and 8 and about which the two arm parts 7 and 8 can be pivoted relative to each other, so that the arm parts 7 and 8 together with the pivot 9 an articulated arm Formation.

With a fitting part 5, the flap holder 1 is attached to the furniture body 4, in particular on the side wall 4b and with a fitting part 6 on the furniture flap 3. On the fitting part 5, a pivot bearing 11 is formed, on which the arm part 7 is pivotally mounted about a pivot axis of the pivot bearing 11 and attached to the side wall 4b. The fitting part 6 has a further pivot bearing 10, with which the arm part 8 is articulated pivotably on the furniture flap 3. Preferably, the rotational or pivot axes of the pivot bearing 10 and 11 and the hinge axis of the rotary joint 9 are arranged parallel to each other, whereby the flap holder parts 5, 6, 7, and 8 in parallel planes and possibly in a single common plane to each other can be moved. For a comparatively simple installation and undisturbed use of the flap holder 1 and the furniture flap 3 can be achieved.

On the arm part 7 is fixed in a central portion which is located between the pivot bearing 11 and the pivot joint 9, a support means 12 is formed. On the support means 12, two springs 13 and 14 are anchored, which can provide compressive forces in opposite directions. Preferably, the arm member 7 is formed in the form of a hollow profile rod, in particular in which the support means 12 and optionally the springs 13 and 14 are at least partially accommodated. Because the support means 12 is fixedly mounted in the arm part 7, the stress states of the two springs 13 and 14 do not influence each other.

The spring 13 is clamped against a pivot bearing (not shown), at which e.g. roller-shaped pressure piece 15 is rotatably mounted. In this case, the pressure piece 15 along the longitudinal axis of the arm part 7 is displaceable. The spring 13 is provided to provide a pressing force with which the pressure piece 15 is pressed in the direction of the pivot bearing 11 and to a control cam 17. Similarly, the spring 14 is provided in an opposite direction a roller-shaped, rotatably mounted pressure member 16 away from the support means 12 and to press a control cam 18 which is disposed between the pressure piece 16 and the pivot joint 9.

The control cam 17 may be connected to e.g. disc-shaped bearing portion 5a of the fitting part 5 may be formed, which may be located in particular at a distance from an inside surface of the side wall 4b. The cam 17 may be formed along a lateral outer edge or a narrow side of the disc-shaped bearing portion 5a, wherein the control cam 17 extends circumferentially on the bearing portion 5a over an angular range corresponding to a pivoting range of the arm portion 7, when the furniture flap 3 of a closed and a opened state and vice versa is moved.

The support means 12, the spring 13, the pressure piece 15 and the control cam 17 together form a first control device 19 which is provided to support closing movements of the furniture flap 3. Like in the FIG. 1 is shown, there is a point of contact of the pressure piece 15 and the control cam 17 at an open position of the furniture flap 3 and the corresponding position of the arm portion 7 at a greater distance from a rotational axis of the pivot bearing 9 as in a closed position of the furniture flap 3, in FIG. 2 is shown. When opening the furniture flap 3, the spring 13 is compressed. In this case, the control device 19 can decelerate an opening movement of the furniture flap 3 and correspondingly released position energy of Store the furniture flap 3 by compression of the spring 13, which can then advantageously support a lifting of the furniture flap 3 in the closing direction.

The end portion 8a of the arm part 8 has a further control curve 18, which is formed in the form of a border of the end portion 8a along the outer contour of the end portion 8a over an angular range about the pivot joint 9. With the spring 14 which is supported on the support means 12, a rotatably mounted, in particular roller-shaped pressure piece 16 is acted upon by a force which can move the pressure piece 16 in the direction of the rotary joint 9 and the pressure piece 16 presses against the control curve 18. A pivoting movement with the furniture flap 3 causes the arm parts 7 and 8 are pivoted about the pivot 9 relative to each other, whereby the pressure piece 16 can move along the cam 18 and in particular can roll. The forces generated by the spring 14 can ensure a contact between the pressure piece 16 and the control cam 18, whereby the spring 14 is set in response to an angular position of the arm parts 7 and 8 under tension. In the opposite direction, the tensioned spring 14 acts on the pressure piece 16 and the latter in turn on the control curve 18, which can generate about the pivot 9 torque on the two arm parts 7 and 8, whose direction and force is determined by the course of the control curve 18 and in particular for braking opening movement of the furniture flap 3 over a predetermined angular range of the cam 18 may be formed. Thus, the support means 12, the spring 14, the pressure piece 16 and the control cam 18 together form a second control device 20, with which a force assistance in moving the furniture flap 3 is controlled depending on a tilt position of the furniture flap.

By the roller-shaped, preferably friction-rotatably mounted pressure piece 16, the second control device 20 is also designed such that a closing movement of the furniture flap 3 is facilitated. Accordingly, the Control curve 18 at a location facing the fitting part 6, where the pressure piece is in a closed position of the furniture flap 3, a smaller distance from the pivot 9 than at a remote from the fitting part 6, where the pressure piece in an open state of Furniture flap as in FIG. 2 located.
