Description

The invention relates to a flap holder for a furniture flap, which is adjustable between a closing a cabinet compartment in a furniture body closed position and an upwardly moved open position, with at least one lever which in the use position on the one hand via a first adjusting axis hinged to a side wall of the furniture body and on the other via a second adjusting axis is pivotally connected to the furniture flap, wherein the body-side lever end of the actuating lever eccentric to the first control axis, the movement behavior of the furniture flap force moderately influencing control curve is associated, which cooperates with a lying in her contact pressure piece, wherein control cam and pressure piece on a Spring device are held in contact with each other and one dependent on the pivot position of the actuating lever pivoting moment is exerted on the actuating lever, and wherein the control cam on a movably mounted on the furniture body control cam carrier is held by the spring means in abutment against the pressure piece.

From the AT 007 499 U1 Such a flap holder is disclosed, with a pressure part, which is arranged on the body side and is pressed by a spring assembly on a control cam. The control cam is located on a control part, which is pivotally connected to the actuating lever.

A flap holder is for example also from the DE 10 2004 019 785 A1 known.

The object of the invention is to provide a flap holder of the type mentioned, which is simple in construction and mountable.

This object is achieved by a flap holder with the features of independent claim 1. Further developments of the invention are shown in the subclaims.

The flap holder according to the invention is characterized in that the pressure piece is arranged on the adjusting lever, and that the control cam carrier is mounted pivotably about a pivot axis on the furniture body.

The control cam is thus not attached to the lever, but on the furniture body, which can bring a simplification in the assembly of the entire flap holder. The control curve therefore no longer needs to be mounted first on the adjusting lever and then in the next assembly step together with the control cam pivotally mounted on the furniture body, but the control curve can be mounted independently of the control lever. On the lever is the pressure piece, which can be compared to a lever side control curve easier there attached.

In addition, it can be prevented by the body-side attachment of the control cam, that this can swing out as in the case of an arrangement on the lever during pivoting of the actuating lever with the cupboard, which could be disturbing from an optical point of view.

Preferably, the spring device on the one hand pivotally coupled to the furniture body and on the other hand articulated via a hinge point with the cam carrier. Advantageously, therefore, both the cam carrier and spring device are pivotally mounted on the furniture body.

Alternatively, it is also possible to store the spring device linearly movable on the furniture body. Again, a linear guide unit can be used. It is possible that the cam holder has a bearing in the direction of serine pivot axis to and away from this displaced by the spring device loaded bearing part. As a result, the leverage ratios present on the control wheel carrier and thus also the pivoting moment exerted on the control lever can be changed.

FIG. 3

an enlarged view of the detail X from FIG. 2 ,

The FIGS. 1 to 3 show a preferred embodiment of the valve holder 11 of the invention. The flap holder, 11 is arranged on a cabinet, in particular wall unit, which is attached hanging in height on a building wall. The body 12 of the cabinet has two opposite, vertical side walls 13, of which only one is visible in the drawing, a bottom wall 14, a cover wall 15 and a rear wall and contains a limited by these walls cabinet tray 16. The front of the cabinet compartment 16th is associated with a furniture flap 17, which occupies a vertical position in the closed position and the cabinet compartment 16 closes. The furniture flap 17 can be adjusted from this closed position into an access to the cabinet 16 gestattende open position, the opening movement on the in the FIGS. 1 to 3 shown intermediate position 18 is made upward.

The furniture flap is described below by way of example with reference to a two-piece furniture flap, which could also be referred to as a so-called folding flap. It is of course possible to use the flap holder according to the invention also in connection with a one-piece furniture flap.

The furniture flap 17 is divided into two by way of example and is formed by an upper flap part 19 and a lower flap part 20, which are hinged together on a hinge axis 21. The hinge axis 21 is usually formed by two hinges 22 each arranged on one of the two lateral end regions of the furniture flap 17. The hinge 22 may include an upper hinge portion to be fastened to the upper flap portion 19 and a lower hinge portion to be attached to the lower flap portion 20 which are hinged together by means of a hinge pin or the like forming the hinge axis 21. The Both hinge parts can be attached to the cabinet compartment 16 facing inside of the flap parts 19, 20. The hinge axis 21 can be arranged near the joint between the two flap parts 19, 20 or even with a certain distance above or below the joint.

The upper flap portion 19 is also still mounted about a hinge axis 23 pivotally mounted on the furniture body 12. This hinge axis 23 is preferably located on the ceiling wall 15 of the furniture body 12th

In the closed position, the lower flap part 19 connects to the underside of the upper flap part 20 in extension thereof, so that the two flap parts 19, 20 are coplanar with each other. When transferring into the open position, the two flap parts 19, 20 perform opposing pivotal movements by the upper flap part 20 from the cabinet compartment 16 and thus the furniture body 12 pivots away, while the lower flap part 20 from its coplanar upper flap part 19 about the hinge axis 21 for Cabinet 16 and thus the furniture body 12 pivots out, so that the furniture flap 17 is folded, so to speak.

The flap holder 11 has at least one adjusting lever 24, which is hinged in the position of use on the one hand via a first adjusting axis 25 with the side wall 13 of the furniture body 12 and on the other hand via a second adjusting axis 26 with the furniture flap 17, in particular with the lower flap part 20 ,

At the body-side lever end 27 of the control lever 24 is a pressure piece 28, in particular in the form of a roll. The pressure piece 28 is force-moderately from a to the first control axis 25 eccentric, the movement behavior of the furniture flap 17 overrun control cam 29, which in turn is formed on a cam carrier 30. The cam carrier 30 is in turn acted upon by a spring device 31 which holds the cam carrier 30 and thus the control cam 29 in abutment against the pressure piece 28. The cam carrier 30 is pivotally mounted via a pivot axis 32 on the furniture body 12, in particular on a mounting plate 33 mounted there. As in particular in FIG. 1 shown, the adjusting lever protrudes with a part of its lever end 27 on the outside of the furniture body 34 facing away from the cam carrier, wherein the first adjusting axis 25 is in the region of the cam carrier 30. Preferably, the adjusting lever 24 has a slotted lever end 27 with two mutually parallel Hebelendteilen 35, 36, which are spaced from each other and span a gap in which the control cam 29 dips on the cam carrier 30. Of course, it is alternatively also possible to form the cam carrier two-piece with two support parts, in which case the body side lever end 27 of the control lever 24 can dip into the space between the support parts and the pressure roller on both the left also runs along the right support part.

Adjusting means are provided with which the force with which the control cam 29 is held against the pressure piece 28 can be adjusted so that adaptation to the weight moment of the furniture flap 17 can take place.

For this purpose, the cam carrier 30 has a bearing part 37 that is displaceably mounted in the direction of its pivot axis 32 and away from it by the spring device 31.

The adjustment of the bearing part 37 in the direction of the pivot axis 32 to and away from this can be done in principle in various ways. An expedient possibility is that on the cam holder 30 in a direction of adjustment 38 ( FIG. 3 ) extending adjusting spindle 39 is rotatable and fixedly mounted in its longitudinal direction, wherein the bearing part 37 is seated on the adjusting spindle 39 and is in threaded engagement with this. If the adjusting spindle 39 is rotated by means of a suitable tool, for example a screwdriver, the bearing part 37 is displaced along the adjusting spindle 39. As a result, the lever ratios present on the cam carrier 30 and thus also the pivoting moment exerted on the adjusting lever 24 change.

The spring device 31 may have at least one pressure or tension spring element. As spring types are gas spring and / or coil spring into consideration. The in the FIGS. 1 to 3 Spring device 31 shown by way of example has a housing 40, which is constructed from a first housing part 41 and a second housing part 42. The first housing part 41 is pivotally mounted on a housing pivot axis 43 on the furniture body 12, in particular on the fitting plate 33. In the housing 40 are parallel-connected spring elements in the form of helical compression springs 44 which are each guided on a rod-like spring carrier 45 and are supported on the one hand on the first housing part 41 and on the other hand on the second housing part 42. The second housing part is arranged relatively movable to the first housing part, so that the pressure force of the helical compression springs 44 can be transmitted via this second housing part 42 on the cam carrier 30.

There is a hinge point 46 between the second housing part 42 and the bearing part 37, whereby the spring means 31 and the steuerkürventräger 30 hinged together are coupled. The articulation point may, for example, be provided by a projection 47 protruding outward from the second housing part in the direction of the cam carrier 30 (FIG. FIG. 3 ) and an abutment portion 48 cooperating with the projection 47 (FIG. FIG. 3 ) are formed on the bearing part 37.

In the closed position, the pressure piece 28 is located at the lower end of the control cam 29. The pressure piece 28 is located beyond the first adjusting axis 25, whereby a pivoting moment is exerted in the direction of the furniture body 12 out, so that there is a locking force. Now, if the furniture flap 17 is opened, the pressure piece 28 moves along the cam 29 along to a dead center in which the normal to the tangent passes through the point between the control cam 29 and pressure piece 28 in a line with the first control axis 25, which essentially no Moment is initiated on the lever 24. If now the furniture flap 17 is opened further, the pressure piece 28 moves to the other side of the first adjusting axis 25, and reaches the in the FIGS. 1 to 2 illustrated intermediate position 18. In this intermediate position 18 a pivoting moment is exerted in the opening direction, which is directed against the flap weight. Thus, an opening force is generated which acts to assist opening. By corresponding contouring of the cam 29, the furniture flap 17 can remain in any open intermediate position.
