Abstract

The fitting has an effective force lever arm (KL) changeable between a swivel axle (7) and a point of application of force. A pivotable furniture part (1) is subjected to an effective moment supporting an opening movement and/or closing movement and/or holding of the furniture part by changing the force lever arm by an adjusting device (19) and a hinge-joint lever (6). A hinge-joint lever arm is designed as the adjustment device on the hinge-joint lever.

Description

The present invention relates to a furniture fitting for pivoting a furniture part of a piece of furniture, for example for pivoting a furniture door of a kitchen cabinet furniture, with a pivotable about a pivot axis of the furniture fitting mounting arm of the furniture part, with a force storage and at least one pivotable about the pivot axis hinge lever, wherein on the hinge lever a Zugkraft- or a pressure force transmitting element with a power transmission direction (KR) engages and on the hinge lever and an adjusting device, the pivoting of the furniture part influencing torque is adjustable.

Furniture fittings of the aforementioned type are used for example as lift fittings to swing a front door or another door element of a kitchen cabinet, such as a wall unit, from a closed position about a horizontal axis and hold in this open position. It is possible, for example, to make a part of the opening movement spring force support, for example, up to the maximum Aufschwenkstellung or even to an open position, from the user then without appropriate opening force support has to be moved up the furniture door to be moved up. The Opening and closing movements should be as controlled as possible and be as comfortable as possible for the user.

From the EP 1 172 048 A2 is a kitchen cabinet with a liftable and lowerable support plate for shelves is known in which a pivotable by a pull and pressure element hinge lever is provided, with which the support plate is pivotally connected. For this purpose, connecting parts are provided, where the hinge lever and the holding plate attack and in which the pivot axis is defined. At these holding parts additionally engages a tether, which is also attached to the holding part, wherein at the opposite end of the holding plate of the hinge lever, the tether is fixed. This retaining band is to be placed over a curved region of the retaining element, wherein this curved portion has a constant radius. However, since this radius extends at a distance from the pivot axis of the hinge lever, this results in a lever arm, so that a torque transmission is possible in the case of pivoting.

However, this does not produce a changing torque in order to prevent, in the event of the door being swung open, e.g. to generate a closing movement counteracting torque.

It is an object of the present invention to provide a furniture fitting of the aforementioned type, with which different torques can be achieved in the course of the opening movement of the furniture part.

To solve this problem, the furniture fitting of the type mentioned is characterized in that on the hinge lever, the tensile force or pressure force transmission element engages the adjusting device, wherein the adjusting device is pivotable about the pivot axis of the furniture fitting that the force application point (KA) of the train or Pressure force of the traction or pressure force transmission element on the adjustment of a positive or negative moment on the furniture part generating operating position and after passing through a zero point (extended position) in an opposite sense generating another operating position (± page side change) can be transferred, the effective Krafthebelarm between the pivot axis and the force application point (KA) is variable and by the change of the Krafthebelarms on the adjusting and the hinge lever, the pivoting furniture part in the course of its opening or closing movement with a Opening movement and / or the closing movement and / or holding the furniture part supporting effective moment can be acted upon.

For this purpose, a hinge lever arm is preferably provided on the hinge lever as an adjusting device, on which the traction or pressure force transmission element engages. Alternatively, a fixed or a variable cam may be provided as an adjusting device on the hinge lever, to which the tensile and / or pressure force transmission element engages at a distance from the pivot axis of the hinge lever.

About the tensile or compressive force element and the adjustment is a the opening movement, the closing movement or holding the furniture part supporting effective moment (support torque) to achieve, which initially depends on the tensile or compressive force of the traction and / or pressure force transmission element or the energy storage , but also by the effective lever arm (KL), which is applied perpendicular to the direction of force (KR) of the tensile force or compressive force through the center of the pivot axis of the hinge lever. This is the point on the adjusting device, on which the pressure force transmitting element or the tensile force transmitting element acts on the force application point (KA), ie where the force (K) in the non-rotatably connected to the hinge lever transmission element, that is usually in the adjustment as For example, a cam is initiated. The force (K) multiplied by the respective changing lever (KL) generates the respective assisting moment of action.

In the course of the pivoting path of the furniture part have moments of action different directions of action, so that arise as totals of the respective supporting moments and the moments of the furniture part overall moments. The influencing possibilities of the total torque are given by influencing the force magnitude (K), the direction of force (KR) and / or the Krafthebelarms (KL).

By the solution according to the invention in particular the influence of the effective Krafthebelarms (KL) and to a lesser extent, an influence of the force direction (KR) is possible. Since in the solution according to the invention the force lever arm (KL) is changed, is via the adjusting device, such as a Zugkurvenscheibe, the torque almost optimally as a large component of the force of the energy storage in the non-rotatable transmission means, so the hinge lever to initiate, so that depending on the location of the force application point (KA) only a very small residual component remains, which is to be collected as a radial force from the pivot axis. This results in a very large variability of the rear heel in an example designed as a cam adjustment.

There are a total of the low radial forces only small surface pressures between the adjustment and the power transmission elements available. The adjustment, for example, the cam can therefore consist of less solid material and also have a relatively rough surface. The bearings of transmission and locking means are less loaded and low friction. The adjustment can also be adjusted against the acting radial forces under load to change the effective Krafthebelarm.

The largest component of the adjustment of the force application point (KA) takes place in the direction of the pivot axis. As a result, essentially the lever arm and less the direction of force is adjusted. For the change of sign of the moment to be applied after passing through the zero position or the extended position can change the side of the furniture fitting of the mechanical force application point (KA) with respect to the pivot axis, so that it is thereby made possible on the one hand to adjust the closing movement supporting effective moment and the other a moment supporting the opening movement.

Preferred dimensions of the maximum swing angle is taken into account such that a closing movement supporting effective torque over an angular range of the maximum opening swing angle of 0 to 40 ° is taken into account, the opening movement of the pivoting furniture part supporting effective torque over a maximum swing angle range of 10 to 85% and in one area between 50% and 100% of the maximum opening swivel angle can be adjusted via a neutral moment of action, so that then the furniture door is held against the weight. Overall, a furniture fitting is thus provided, in which individually a supported closing, a desired closing force against a desired opening, holding and / or the opening movement supporting lifts can be adjusted.

For this purpose, a tension band is provided that is at least regionally, but also completely flexible, which acts either on a hinge lever arm or on a cam disk, for example. This tension band can, for example, wrap around a cam in its curve region, for example over a range of 180 °, so that in the course of the pivoting movement of the door to be pivoted with the lever arm and the cam, the tension band unwinds from the curve wall, and with the effective force application point in a situation is transferred in which the closing movement is no longer supported, but due to the force application points an opening movement is supported or a hold. This can be done with simple means, depending on how the force application point position is selected or the cam is designed.

In addition, it is possible that the furniture fitting has a hinge lever which is part of a hinged lever unit provided with at least one adjusting device, which allows an adjustment of a characteristic of the torque, in particular after installation of the furniture hinge, wherein the adjusting device for generating a maximum torque and / or Torque curve is formed during the pivoting.

The torque, which rests on the axis of rotation on the mounting arm due to the weight of the furniture part, or acts on these, is thus influenced by a variable torque. In the superimposition of the two torques is then adjusted by the adjustment option optimal on the particular circumstances ease of use. The mounting arm, which is also referred to as an actuating arm, can hereby be connected to the hinge lever via a hinge connection, but it can also be a fastening arm connected in one piece with the hinge lever.

For optimal mobility of the furniture part to be pivoted advantageously a four-hinge hinge is used, in which the hinge lever is hinged to the mounting arm and this is itself pivotally fixed to a second hinge lever, which in turn is pivotally mounted on the furniture. Together with the axis of rotation about which pivoted the pivot lever of the furniture hinge, thus resulting in a roughly parallelogram-like leadership of the furniture part. Depending on the furniture part used For example, the maximum torque may be adjustable to catch the weight of the furniture part. This takes place, for example, via a tension of a traction-force transmission element or via an adjustment of a pressure-force transmission element.

Advantageously, the tensile force transmission element is a flexible tension band, which is optionally supported by a spring. The force which can be exerted on the hinge lever by this tensile force transmission element, but in the same way as that of a pressure force transmission element, is advantageously applied thereto via a force application point (KA) which can be varied relative to the axis of rotation and in a plane perpendicular thereto by the adjustment device. The torque applied to the hinge lever due to the varying distance of the point of application of force to the axis of rotation during pivoting thus changes during pivoting. For example, this can lead to an increase or a weakening of the torque exerted by the tensile / compressive force transmission element, so that different phases of movement of the furniture part are passed in accordance with a desired characteristic of the force exerted on the mounting arm or caused by this on the furniture part torque. Advantageously, the lane expired from the point of attack or this itself can vary over the adjusting means.

In an advantageous embodiment of the invention, the force application point is the point of articulation of the tension band or of the tension lever, which in turn itself is pivotally fixed to the hinge lever at least in a partial area.

Due to the relative movement of the pull lever during the movement of the hinge lever, that is, during the pivoting of the furniture part, a varying torque is generated, which is superimposed in the different phases of motion generated by the weight of the furniture part torque and so support, for example, a closing phase as well as an opening phase can.

Particularly advantageous is an embodiment of the hinge lever unit with a replaceable or a variable via an actuating means relative to the axis of rotation cam. Usually used tensile or compressive force transmission elements can run on the outer surface of the cam along a curved path, so that the different phases of the supported or influenced movement of the cabinet door or the furniture part result.

For example, the curved path is to be designed so that in a first phase of the opening movement, a torque is generated, which acts in the closing direction. In a phase subsequent to the first phase, a moment is generated which acts in the direction of opening. That is, with respect to the center of gravity of the system, the point of application has shifted to the other side of the rotation axis and supports the opening movement. In a third phase, the outer surface of the cam track or that of the point of application about the axis of rotation be running track formed such that the resulting torque is approximately zero, that is, the movement of the furniture part is optionally also stopped by the system immanent friction and the furniture part remains in position. In this case, a resultant torque of weight and by pulling / pushing means is about 0.

By means of the adjusting means, the adjustment of the torques can be made particularly preferably after installation of the furniture part, so that, for example, a resulting torque is exactly 0 if the furniture part is held at the desired height relative to the opening.

Advantageously, the cam, which may optionally be formed integrally with the hinge lever or is also fixed to this, an adjustable part, which can be influenced via the actuating means. This adjustable part can be flexibly and / or hingedly connected to the remaining part of the cam, which simplifies the assembly of the furniture hinge.

In such a preferred embodiment of the invention is changed by the change in the outer cam track of the cam, for example via an adjustable fixing the cam on the hinge lever, the tensile force exerted by the traction means and thus their effective component. On the one hand, this causes a change in the tensile force applied to the point of application, at the same time also a change in the correspondingly effective component of the tensile force.

In the drawing, generally equivalent parts are provided with corresponding reference numerals.

In Fig. 1 an inventive piece of furniture is disclosed which has a designed as a front panel furniture part 1. This furniture part 1 closes a forwardly directed opening of the designed in this case, for example, as a wall unit furniture whose body upper and lower sides 2, and a rear wall 3 includes. The piece of furniture is, for example, a kitchen piece of furniture with a shelf 4 and has on at least one side, but advantageously also on both sides in Fig. 2 closer explained lever mimic the furniture hinge or furniture fitting on.

The furniture hinge according to the invention comprises in the in Fig. 2 illustrated embodiment a arranged on the furniture part 1 mounting arm 5, to which a hinge lever 6 is hinged. The hinge lever 6 is pivotable about a rotary or pivot axis 7. At the end facing away from the furniture part 1 of the mounting arm 5, a further hinge lever 8 is hinged, which in turn pivots about a further pivot axis 9. The rotary or pivot axes 7 and 9 form, together with the joints 10, a four-joint system, by means of which the movement of the front flap or of the furniture part 1 is forcibly guided. As a force storage a pressure cylinder 11 is used, which is fixed on the one hand as the pivot axes 7 and 9 movable on the side wall 12 and on the other hand via a slotted guide 13, which in turn is pivotable about an axis 14, acting on a tension band 15. The drawstring 15 forms together with the slotted guide 13 and the impression cylinder 11 a generally numbered 16 tensile and / or pressure force transmission means.

The drawstring 15 with the tensile force KR is connected via a pivotally mounted on the hinge lever 6 pull lever 17 with the hinge lever 6. An adjusting device 18 embodied as an eccentric here serves to set a torque exerted by the energy accumulator 11 on the link guide 13 and the drawstring 15 on the hinge lever 6, by means of an adjustable or variable lever arm KL perpendicular to the drawstring 15 with the traction force KR is applied through the center of the pivot axis 7.

For example, if the in Fig. 2 shown eccentric rotated by 90 ° counterclockwise, the pull lever 17 is also pivoted counterclockwise and the pressure cylinder 11 is compressed more. Consequently, the front door or the furniture part 1 is held with a larger force in its closed position. At the same time, due to the changed lever arm KL, the course of the torque during the opening movement also varies, ie altogether the characteristic curve of the resulting torque characterizing the pivoting of the piece of furniture is varied. In particular, the course of the opening movement and the closing movement is already variable in the mounted position, which is accompanied by a high ease of use of the piece of furniture. This setting can for example also be made at the factory after assembly of the furniture.

Instead of a rigid pull lever 17, the corresponding section can be formed as an extension of the tension band 15 also flexible, resulting in an additional Change in torque results. In this case, the flexibility can be chosen so that this flexible part of the tension band 15 at least partially surrounds the eccentric 18.

The hinge lever unit 16 thus comprises at least the tension band 15 and the pull lever 17 and the eccentric or the adjusting means 18.

In a further embodiment according to Fig. 3 The hinge lever unit 16 has a cam disk 19, which is arranged on the hinge lever 6 and which is split in several parts and comprises, in addition to a base part 20, a part 21 which can now be adjusted by means of a screwing means 18. This part 21 is guided on two sides of the base part 20 and has an toward an elastic outer web 22 in the Fig. 3 differently shaped surface. By pushing out the adjustable part 21, which is also referred to as an extendable plunger with an outer curved track in the left direction in the figure and thereby taking place changing the elastic web 22, the cam is replaced by another peripheral shape, so that a running on this cam disc Tieback relative to the rotary or pivot axis 7 another torque on the pivot lever 6 exerts than in the non-extended and in the Fig. 3 shown (outer) shape of the cam 19th

At least a portion of the peripheral shape of the cam is thus variable relative to the pivot axis 7, which is characterized by varying between the articulation point of a tension band on the outer peripheral surface distance and the between Tieback attack point and pivot axis resulting angle other leverage and corresponding torques on the swing arm or hinge lever 6 result.

In the following figures, various embodiments of the invention with respect to the hinge lever 6 at least relatively changed outer circumferential tracks, which lead to a change in the torque characteristic of the pivot lever, further shown. Common to these variants is that the adjustment of the cam or its change, for example, by replacing the cam in the direction of a plane that is vertical to the pivot axis or axis of rotation 7.

In the Fig. 4a is the cam 19 in the plane of the figure about the adjusting means 18 and pivotally fixed by this. A double arrow 23 in this case indicates the direction in which the cam disc 19 can be adjusted and then changes according to the numbered in the figures by 24 cam track relative to the pivot axis 7, whereby the corresponding lever and the torque, which is different from the weight of the furniture part 1 applied torque superimposed, varies.

According to the double arrow 23 of the Fig. 4a describe the double arrows 23 of the Fig. 4b and 4c the displaceability of the cam plate 19 along the slide link guide 18, 19.1 shown, by means of which the cam plate 19 relative to the hinge lever 6 is movable.

A substantially based on the same principle of action, via an adjusting means 18 variable cam 19 with an adjustable part 21 is in the Fig. 5 a, b, c, 7, 8, 9 and 10, in which changes the touched by a tension band 15 cam track changes. The comparison of Fig. 5 a to c clearly shows to what extent the force application point 25 (KA) with respect to the pivot axis 7 changes. The adjustable part 21 is in this case connected via a film hinge or an elastically configured part of the cam with the base part 20 fixedly connected to the hinge lever 6.

In the Fig. 7 illustrated variant of the cam 19 has a built-in cam 19 screw over which also the radius of the in the Fig. 7 shown left outer part of the curved path changes. The same applies to the Fig. 8 and 9 in which the variable, adjustable part 21 of the cam 19 is variable by means of a base-adjustable eccentric relative to the hinge lever 6 as adjusting means 18. It is understood that instead of an adjustment by a screw, other adjusting means, such as latching means or the like. Can be used. However, steplessly adjustable adjusting means are preferred.

In the Fig. 10 a variant of the cam is shown, in which two adjusting means 18 can change the curve or circumferential path in each case in different areas. While the closer to the axis of rotation 7 screw 18 has a greater influence on the maximum tensile force, the lower screw 18 is amplified a variation of the torque curve during movement.

The Fig. 6 a to c disclose a variant of the embodiment in which the adjustable cam has been replaced by an adjustably fixed to the pivot lever 6 pull lever 17, wherein the Fig. 6 a to c show different phase of the movement. In the Fig. 6a acts on the pivot lever 6 acting torque in the direction of the closed position of the flap. In the Fig. 6b Due to the large distance of the point of application to the pivot axis and also due to the almost right angle between the connection of point 25, pivot axis 7 and pull rod 26 a nearly maximum torque on the lever or swivel arm or hinge lever 6 is exercised. This torque is in the Fig. 6c again lower, the opening movement is correspondingly less strongly supported and the flap or the furniture part 1 remains depending on the selected setting in its open position.

In the Fig. 11 a to g is in turn a pivotally mounted on the hinge lever 6 arranged cam 19, in which over other parts 27.1 and 27.2 and 27, the cam 19 can be variably held. Here too, the torque acting on the furniture part can be changed during the pivoting process.

In particular, closer to that FIGS. 1 . 2 . 5a to 5c such as 7 . 8th . 9 . 10 such as 12a to 12c it can be seen, in the embodiment shown as a tension element, a tension band 15 is provided, which engages in a slotted guide 13 at one end ( Fig. 2 ) and at the other end to a pull lever 17 is attached. In the course of the movement the door in the open position, the cam 19 is pivoted about the pivot axis 7, whereupon the direction of pull KR and the lever arm KL change. This is closer Fig. 12a, 12b, 12c seen. In this case, a zero position or the inserted position (coaxial with the pulling direction KR) to go through, so that a sign change is achieved at the moment of action.

There is shown an embodiment in which a hinge lever arm 6.1 is provided, which is substantially in the starting position ( Fig. 12c ) extends at right angles to the pivotable furniture part not shown in detail. As shown in more detail attacks on the arrow 15.1, for example, a spring or the slide guide 13, which pulls the drawstring 15 in the direction of arrow 15.1. In Fig. 12a the closed position of the furniture part to be pivoted is shown. If this is now pivoted in the direction of the arrow P, the hinge lever 6.1 and the pivoted with this end of the drawstring 15 reaches the position in Fig. 12b is shown. During the movement phase, the drawstring exerts on the furniture part to be pivoted or on the hinge lever 6 a force which acts in the closing direction. The user therefore has to open the furniture part against this closing moment or against this closing force.

If he moves the furniture part against this closing moment, so a position is achieved, as in Fig. 12c is indicated. In this case, the hinge lever 6 and with it the hinge lever 6.1 is pivoted so far up that now the tensile force KR of the tension band 15 acts on the lever arm 6.1 so that a moment is generated, either - taking into account the weight of the pivotable Furniture part and the associated hinge lever parts - the furniture part holds or lifts, ie transferred in the sense of an opening movement upwards. Depending on the design of the cam 19 this is to be set by simple means, for example by changing the cam or by replacing the cam. The drawstring is a simple building part that can be tied in just a few easy steps. It is low-wear and can be replaced in the case of wear for spare parts with low production costs. Nevertheless, the variety of setting of variable torques and acting in certain phases effective moments is very easy.

In Fig. 13 is shown in two graphs, how the torque is adjustable. Shown by the solid line is the required power torque curve of a pivoting furniture part on the rotation angle of the pivoting furniture part, ie up to the maximum opening angle from the position "flap to" up to the position "flap open". It can be seen that a closing phase is followed by a holding phase and then a lifting phase. In the in Fig. 13 In the lower illustration, the lift phase and the hold phase are swapped. This is followed by the closing phase, first a lift phase and then a holding phase. This can be displayed with different Zugkurvenscheiben.

In the in the Fig. 14 a, b, c shown embodiment of the invention, the adjusting device comprises a fixed to the lever 6 bolt 31, which during the movement phase, by the Fig. 14 a, b, c is clarified, pivoted together with the lever 6 about the pivot axis 7.

By the pivoting of the bolt 31 of this enters the in Fig. 14b shown investment position with the drawstring 15 and pushes it in the direction of the printing cylinder eleventh

The hinge lever 6 pivots this far until a balance between the caused by the weight of the furniture part and the drawstring 15 and caused by the bolt 31 and the point 25 on the pivot arm 6 moments is reached.

The Fig. 15 a, b, c disclose a variant in which the bolt 31 is fixedly arranged on the base plate of the furniture hinge. Only when pivoting the furniture part about the pivot axis 7 due to an extension of the printing cylinder 11 and a transmission of the resulting forces by means of the tension band 15 this passes with the bolt 31 in the Fig. 15b shown investment position. The deflection caused by the bolt leads in this embodiment of the invention due to the fixed relative to the base plate position of the bolt 31, which does not mitverschwenkt to a deflection of the tensile forces around the bolt 31 so that this starting from the point of attack and considered on the pivot axis 7 a unfold optimal moment of action. This moment of action can be adjusted as desired by arranging the bolt and shape of the cam 19 so that, for example, the pivoting movement is supported or favorable leverage for a rest position of the furniture part can be created.

In the drawing, generally equivalent parts are provided with corresponding reference numerals.
