Description

The invention relates to a flap holder for a vertically ver pivoted on a furniture body, by swiveling up opening flap to hold the flap in its open position by means of a spring arrangement.

The top cabinet compartment is particularly common in tall cabinets by one in the area of its upper edge on the furniture body steered closed flap that pivoted upwards to open becomes. Such a flap is regularly a flap holder orders who should keep the flap in its open position. there standard flap holders contain a lever linkage and a spring arrangement so that the lever linkage runs over a dead center position. If you close the flap, it will reach after the Dead center not only their weight but also the spring force, which can lead to violent slamming of the flap.

In this connection, the present invention is based on was based on creating a flap holder principle with which  in a relatively simple manner the respective requirements appropriate movement behavior of the flap.

This object is achieved in that the flaps Connect the holder to the flap so that it can be pivoted about a pivot axis bar flap-side arm part and a swivel around a swivel axis bar with a fitting part to be attached to the furniture body whose body-side arm part, the flap or end areas opposite the furniture body about an axis of articulation are pivotally connected to each other so that a knee lever like arrangement is formed, and that between the body side arm part and the fitting part a first control device and between the body-side arm part and the flap-side Arm part a second control device is effective, the at the control devices each have a pressure piece and a tax curve included by one of the other tax device independent spring device held against each other are, so that the flap holder depending on the Swing angle of the flap force exerted on the flap from two each occurring at one of the control devices Kraftkom components.

When the flap is swiveled, the body-side swings Arm section around the body-side pivot axis. Also swivel the two arm parts on the hinge axis relative to each other. These two swiveling movements are forceful by the two Control devices and in connection with the spring devices  determined by the course of the control curves. Since the two control devices are independent of one another, one obtains two power components, depending on the course of the control curves be opposite to each other in certain swivel angle ranges or can also increase or be zero.

Expediently, when the flap holder is mounted, the Open position on the flap hold-open force and the in the locking force exerted at least essentially in the closed position Lichen by another of the two control devices certainly. Each of the two control cams can be one to facing pivot axis or hinge axis at least essentially have concentric curve area, in the locking position tion and in the open position at one of the tax offices directions the thrust piece rests on the concentric curve area.

Furthermore, it is expedient that the two control devices when opening and closing the flap one after the other are effective between arranged overlap area.

With a flap holder designed according to the invention, easily shape the control curves so that such a damped closing behavior means that no slamming must be feared. It can even be achieved that Flap over a large angular range in intermediate positions stop.

In a preferred embodiment it is provided that at at least one of the spring devices adjustable the spring force  is. In this way you can the flap holder without any other Ver changes to the personal needs of the user or to adjust the valve weight.

An embodiment of the invention will now be based on the drawing explained in detail. Show it:

Fig. 1 a mounted in a cabinet flap holder in vertical longitudinal section, the flap is closed, and

Fig. 2 shows the arrangement of FIG. 1 with the flap open.

From the drawing, the upper front area of a cabinet emerges in vertical cross-section, so that from the cabinet body 1 one of the side walls 2 , the top wall 3 forming the cabinet ceiling and a shelf 5 delimiting the uppermost compartment 4 are visible. The front of the compartment 4 is assigned a flap 6 which is pivotally attached to the body 1 between a compartment 4 closing, ver tical closed position ( Fig. 1) and a pivoted up, the access to the cabinet compartment 4 opening position ( Fig. 2). The swivel fitting, via which the upper end region of the flap 6 in the closed position is pivotably connected to the body 1 , has been omitted in the drawing. It is of a conventional design and is otherwise of no further interest in the present context.

The flap 6 is connected to the cabinet body 1 and thereby to the side wall 2 thereof via a flap holder 7 in addition to the swivel fitting. With the help of the flap holder 7 , the flap 6 is held in its open position shown in FIG. 2.

The flap holder 7 has a flap-side arm part 8 and a body-side arm part 9 , which form a toggle-like arrangement. The relevant end of the flap arm part 8 is pivotable about a pivot axis 10 with the flap 6 a related party. For this purpose, the articulation axis 10 sits on a fastening shoe 11 , which is screwed onto the flap 6 , in the exemplary embodiment to the inside of the flap facing the inside of the cabinet in the closed position. The end of the body-side arm part 9 opposite the flap-side arm part 8 , on the other hand, is pivotably connected about a pivot axis 12 to a fitting part 13 belonging to the flap holder 7 , which is fixedly attached to the furniture body, in the exemplary embodiment on the side wall 2 . The mutually facing end regions of the two arm parts 8 , 9 are pivotally connected to one another via an articulated axis 14 , so that the two arm parts 8 , 9 are arranged in a V-like manner with respect to one another. In the closed position according to FIG. 1, the two arm parts 8 , 9 are at a relatively small acute angle to one another, with both arm parts, starting from the flap 6 or the fitting part 13 , extending upwards. In the open position of FIG. 2, the two arm parts 8, 9 of the voneinan pivoted away and be almost a straight position a.

The flap holder 7 contains two control devices 15 , 16 , of which the first control device 15 is effective between the body-side arm part 9 and the fitting part 13 and the second control device 16 between the body-side arm part 9 and the flap-side arm part 8 . The two control devices 15 , 16 each hold a pressure piece 17 or 18 and a control cam 19 or 20 , which are held against one another by a spring device 21 or 22 . The two spring devices 21 , 22 are independent of one another.

In the exemplary embodiment, the two pressure pieces 17 , 18 are arranged on the body-side arm part 9 . Accordingly, the control curve 19 assigned to the pressure piece 17 is located on the body-side fitting part 13 and the control curve 20 assigned to the pressure piece 18 is located on the flap-side arm part 8 . In principle, in the case of one and / or another control device, the arrangement could also be reversed in such a way that the control cam is seated on the body-side arm part.

The spring device 21 or 22 acts on the respective pressure piece 17 or 18 facing the control cam 19 or 20 .

The body-side arm part 9 has a tubular shape. The two pressure pieces 17 , 18 are accommodated in the interior of this tubular arm part 9 on the body side. Of course, embodiments are also conceivable in which only one of the pressure pieces is located inside the arm part.

Each arranged on the body-side arm part 9 pressure piece 17 or 18 has a longitudinally displaceably guided on the arm part 9 bearing part 23 or 24 and a rotatably mounted on the bearing part 23 or 24 , pressure roller 25 or 26 abutting the relevant cam 19 or 20 on, which rolls on the control cam 19 or 20 when pivoting the flap 6 .

The two spring devices 21 , 22 are each a compression spring device which is supported on the one hand on a spring arm 27 arranged in the interior of the body-side arm part 9 and 28 and on the other hand on the pressure piece 17 and 18 in question . The two compression spring devices 21 , 22 are formed by coil springs. In the case shown, the spring device 22 is two helical springs placed one inside the other. This variant would also be possible in the spring device 21 , which is formed in the exemplary embodiment only by a helical spring. Conversely, only one helical spring could also be provided in the spring device 22 .

The spring stops 27 and 28 are located in the longitudinal direction of the body-side arm part 9 between the two pressure pieces 17 , 18 and extend from the associated spring stop in the arm part longitudinal direction to the pressure piece in question. The pressure pieces shown have on their bearing section 23 or 24 one of the Federein device 21 or 22 facing bearing recess 29 or 30 into which the spring device 21 or 22 in question is immersed and is supported on the bottom of the bearing recess 29 or 30 .

In at least one of the spring devices, in the embodiment example on the spring device 22 , the spring force is adjustable, so that the force exerted by the flap holder 7 on the flap 6 and its dependence on the pivoting angle can be changed. This is achieved in the embodiment in that the spring means of the adjustable shock 22 associated Federan 28 9 can be ver represents in longitudinal direction of the arm portion körpusseitigen. For this purpose, the adjustable spring stop 28 is formed by the head 31 of a threaded bolt 32 , which is in threaded engagement with a threaded nut part 33 . The threaded bolt 32 and the threaded nut part 33 are located within the tubular arm part 9 . The threaded bolt 32 is non-rotatable but is adjustable in the longitudinal direction of the arm part, for example by forming longitudinal notches (not shown) into the wall of the flap-side arm part 9 , which cooperate with the polygonal, in particular hexagonal, threaded bolt head 31 . The threaded nut part 33 , on the other hand, is rotatable, but is arranged in a fixed manner in the longitudinal direction of the arm part. The threaded nut part 33 is accessible from the outside, for example by having several plug-in recesses 34 distributed over the circumference and the wall of the arm part 9 having a circumferentially extending transverse slot 35 through which an actuating tool, e.g. B. an Allen key, can be inserted into the currently accessible plug-in recess 34 .

The tubular body-side arm part 9 is longitudinally slotted in the region of each pressure piece 17 or 18 arranged in it, the respective longitudinal slot 36 or 37 extending from the end of the arm part to a certain extent in the longitudinal direction of the arm part. Furthermore, the control cam 19 or 20 in question is formed by a control disk 38 or 39 , which is arranged on the body-side fitting part 13 or on the flap-side arm part 8 and engages through the longitudinal slot 36 or 37 , so that the control curve 19 or 20 abuts the pressure roller 25 or 26 . When pivoting the body-side arm part 9 about the pivot axis 12 , the pressure roller 25 pivots along the control cam 19 . The control cam 19 travels through the body-side arm part 9, so to speak. Accordingly, when the two arm parts 8 , 9 are pivoted about the hinge axis 14, the control cam 20 and the pressure roller 26 move past one another, the control cam 20 pivoting through the arm part 8 on the flap side.

The bearing section 23 or 24 of the pressure piece 17 or 18 has two bearing legs directed towards the arm part end, which run on both sides of the pressure roller 25 or 26 and on which the respective pressure roller bearing axis 40 or 41 is mounted. Only one of the two bearing legs is visible, since it is a longitudinal section in FIGS. 1 and 2 (bearing legs 42 and 43, respectively). For each pressure piece 17 and 18 , the two bearing legs 42 and 43 contain a guide slot 44 and 45 , which is plugged into the tubular flap-side arm part 9 on both sides of the control disk 38 and 39 on the pivot axis 12 and the Ge steering axis 14 .

When moving the flap 6 , the body-side arm part 9 pivots relative to the fitting part 13 and the two arm parts 8 and 9 pivot relative to one another. In both places he follows the pivoting depending on the course of the control curve 19 or 20 counter or with the support of the device 15 and 16 occurring at the Steuereinrich device. From these two force components, the flap holder 7 , depending on the pivoting angle of the flap 6, applies this force, which can thus be adapted to the respective application by appropriate shaping of the control curves 19 , 20 .

In the embodiment, the holding force exerted in the open position according to FIG. 2 on the flap 6 is determined at least essentially by the second control device 16 effective between the two arm parts 8 , 9 . The pressure roller 26 is located here at one of the hinge axis 14 closest point of the control curve 20 , from which extends from the hinge axis 14 away curve area 46 to a point 47 at which the curve area 46 in a to the hinge axis 14 in essential con centric curve area 48 passes. At the same time, the pressure roller 25 is located on a to the pivot axis 12 substantially con centric curve region 49 of the cam 19 of the first control device 15 .

When the flap 6 is closed, the pressure roller 26 initially runs on the cam area 46 which is distant from the articulation axis 14 .

For this purpose, a certain actuating force must be exerted on the flap 6 . In the course of this movement, in the first control device 15 the pressure roller 25 arrives at a region 50 of the control cam 19 , which in the exemplary embodiment is essentially radial, away from the pivot axis 12 , so that the closing movement of the flap 6 is countered by a corresponding force component, which together with the force components occurring on the control cam 20 of the second control device 16 results in a so-called damped closing movement.

Shortly before closing, the pressure roller 25 of the first control device 15 reaches an apex 51 of the control cam 19 , so that a locking force is subsequently exerted on the flap 6 . In this phase, the pressure roller 26 moves the second control device 16 along the circular arc-like extending around the joint axis 14 curve portion 48 of the second control device sixteenth

When opening the flap 6 , the corresponding conditions arise in the reverse direction.

Thus, the hold-open force exerted on the flap 6 in the open position and the hold-open force exerted in the closed position is determined at least essentially in each case by one of the two control devices 15 , 16 .

It can be seen that the two control devices 15 , 16 take effect one after the other with an overlapping region arranged between them during opening and closing.

In the closed position, the two pressure pieces 17 , 18 , as can be seen from a comparison of FIGS. 1 and 2, with respect to the open position, a more distant position from the pivot axis 12 or the pivot axis 14 , so that the two spring devices 21st , 22 are more excited.

When the flap 6 is opened, the flap weight is substantially compensated for, so that the opening movement also runs smoothly, so to speak.

The reason for the use of two separate spring devices 21 , 22 is, on the one hand, that the initial forces on both control cams 19 , 20 are the same and that the decrease in force is only caused by the path of the control curve, which is driven in each case. On the other hand, a spring force adjustment can be implemented, as is the case for the spring device 22 in the exemplary embodiment.
