Description

The 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 a kitchen cabinet furniture, with a about a pivot axis of the furniture fitting pivotable mounting arm of the Furniture part, with a power storage as well as with at least a pivotable about the pivot axis hinge lever, wherein on the hinge lever, a traction or a pressure force transmission element with a power transmission direction (KR) attacks and over the Hinge lever and an adjusting the pivoting the furniture part influencing torque is adjustable.

furniture fittings The aforementioned type, for example, as a lift fittings used to be a front door or another door element a kitchen cupboard, for example a wall cupboard, swing open from a closed position about a horizontal axis and to keep in this open position. That's it possible, for. B. a part of the opening movement to make spring force support, for example until towards the maximum swing-up position or also up to an open position, from the user from then without corresponding opening force support has to move up the furniture door. The opening and closing movements should be as possible controlled designed and as possible for the user be comfortable.

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.

In order to however, to produce no changing torque, in case of the swinging of a door z. B. a one Closing movement to produce counteracting torque.

It Object of the present invention, a furniture fitting of the type mentioned above, with the in the course of the opening movement the furniture part to achieve different torques are.

to The solution to this problem is the furniture fitting of the type mentioned above characterized in that on the hinge lever the tensile or compressive force transmission element over the adjusting acts, wherein the adjusting device is pivotable about the pivot axis of the furniture fitting, that the force application point (KA) of the tensile or compressive force the tensile or compressive force transmission element on the Adjustment from a positive or negative moment on the furniture part generating operating position and after passing through a zero point (extended position) in an opposing moment generating other operating position (± lateral change) can be transferred is, wherein the effective Krafthebelarm between the pivot axis and the force application point (KA) is variable and by the change of the Krafthebelarms on the adjustment and the hinge lever, the pivoting furniture part in Course of its opening or closing movement with a the opening movement and / or the closing movement and / or supporting the furniture part supportive Moment of action can be acted upon.

To is preferably on the hinge lever a Scharnierhebelarm as adjusting provided on which the traction or pressure force transmission element attacks. Alternatively, on the hinge lever a fixed or a changeable face cam as adjusting be provided, on which the tensile and / or compressive force transmission element engages with distance to 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 transmission element rotatably connected to the hinge lever, 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 assistive mode ment.

in the Course of the pivoting path of the furniture part have moments of action different directions of action, so that the sum of the respective supporting moments of action and the intrinsic moments of the Furniture part resulting in total moments. The influencing possibilities of the total moment are about influencing the force size (K), the direction of force (KR) and / or the Krafthebelarms (KL) given.

By the solution according to the invention is particular the influence of the effective Krafthebelarms (KL) and in lesser Dimensions also an influence on the direction of force (KR) possible. Since in the inventive solution of Krafthebelarm (KL) is changed, is about the Adjustment, such as a Zugkurvenscheibe, the torque almost optimal as a large component of the force of the energy storage in the non-rotatable transmission means, so the hinge lever, so that depends on the location of the Force application point (KA) only a very small residual force component remains to absorb as radial force from the pivot axis is. This results in a very large variance possibility the rear paragraph at a z. B. formed as a cam Adjustment.

It Altogether are only small due to the low radial forces Surface pressures between the adjustment and the power transmission elements available. The adjusting device, For example, the cam, can therefore from less solid Material exist and also a relatively rough surface to have. The bearings of transmission and detection means are less loaded and less friction. The adjusting device 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) happens in the direction of the pivot axis. This will be in the essentially the lever arm and less the direction of force adjusted. For the change of sign of the moment to be applied after passing through the zero point position or the extended position can in the inventive Furniture fitting the mechanical force application point (KA) ge compared the pivot axis change the side, so that it is possible, on the one hand the closing movement to adjust supporting moment of action and on the other a moment supporting the opening movement.

preferred dimensions the maximum tilt angle is taken into account in this way, that a supporting the closing movement Effective torque over an angular range of the maximum opening swivel angle from 0 to 40 °, one the opening movement the pivoting furniture part supporting effective torque over a maximum swing angle range of 10 to 85% and in one Range between 50% and 100% of the maximum opening swivel angle a neutral moment of action can be set so that then the Furniture door is held against the weight. All in all is provided with a furniture fitting, in which individually a supported closing, a desired opening against a closing force, a holding and / or an opening movement supporting Lifts can be adjusted.

preferred dimensions is at least partially, but also completely flexible trained drawstring provided either on a hinge lever arm attacks or at z. B. a cam. This drawstring For example, a cam in the curve area in areas wrap around, for example over a range of 180 °, so that in the course of the pivoting movement to be pivoted Door with the lever arm and the cam itself the drawstring from the curve wall unwinds, and with the effective force application point is transferred to a position in which the closing movement no longer unsupported, but due to the force application points an opening movement is supported or a hold. This is with simple Means to perform, depending on how the point of force application is selected or the cam is designed.

additionally Is it possible that the furniture fitting a hinge lever, the part of a with at least one Adjusting device provided with a hinge lever unit, which is a Adjustment of a characteristic curve of the torque, in particular after assembly allows the furniture hinge, the adjusting for creating a maximum torque and / or the torque curve is formed during the pivoting.

The Torque, which due to the weight of the furniture part abuts the axis of rotation on the mounting arm, or acts on this, is thus about a changeable Torque influences. In the superposition of the two torques is by the Justagemöglichkeit then on the respective Conditions optimum ease of use adjustable. The as well Stellarm designated mounting arm can this over a hinge joint connected to the hinge lever, it However, it can also be a one-piece with the hinge lever connected bracket acting.

For optimum mobility of the furniture part to be pivoted advantageously a four-hinge hinge can be used, in which the Hinge lever is hingedly connected to the mounting arm and this is itself pivotally fixed to a second hinge lever, which in turn is pivotally mounted on the piece of 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, the maximum torque can be designed to be adjustable, for example, 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, is it in the traction transfer element to a flexible drawstring, which optionally supported by a spring becomes. That of this traction element, however as well as that of a pressure transmitting element on the hinge lever exercisable force is on this advantageously applied via a force application point (KA), the relative to the axis of rotation and in a plane perpendicular thereto the adjustment is variable. That on the hinge lever due to the changing distance of the force application point applied to the axis of rotation during pivoting Torque thus changes during pivoting. For example This can lead to an increase or a weakening of that exerted by the tensile / compressive force transmission element Torque lead, allowing different phases of movement the furniture part according to a desired Characteristic of the force exerted on the mounting arm or of go through this caused on the furniture part torque become. Advantageously, it can be from the point of attack expired train or this itself about that of the point of attack expired train or this itself on the actuating means vary.

In an advantageous embodiment of the invention is at the force application point to the point of articulation of the drawstring or the pull lever, which in turn on the hinge lever at least is pivotally set in a partial area.

by virtue of the relative movement of the pulling lever during the movement of the hinge lever, that is, during pivoting of the furniture part, a varying torque is generated, which in the different phases of movement through the force of gravity of the furniture part generated torque superimposed and so for example a closing phase as well as an opening phase can support.

Especially advantageous is an embodiment of the hinge lever unit with an interchangeable or relative to an adjusting means to the axis of rotation variable cam. Usually used tensile or compressive force transmission elements can here on the outer surface of the cam run along a curved path, so that the different Phases of the supported or influenced movement of the Cabinet flap or the furniture part revealed.

For example is the curved path so that in a first phase of the opening movement a torque is generated which acts in the direction of closing. In a phase that is approaching the first phase then generates a moment which acts in the direction of opening. That is, in terms of the center of gravity the system has the point of attack on the other side of the axis of rotation shifts and supports the opening movement. In a third phase, the outer surface of the Curved track or extending from the point of application about the axis of rotation Track be designed such that the resulting torque is about zero, that is the movement of the Furniture part is possibly also due to the system immanent friction stopped and the furniture part stops in position. In this case, a resulting torque is weight and by pulling / pressure means in about 0.

through the adjusting means, the adjustment of the torques is particularly preferred be made after installation of the furniture part, so that for example, a resulting torque equal to 0 then is when the furniture part in the desired height is held relative to the opening.

advantageously, includes the cam, which may be in one piece may be formed with the hinge lever or fixed to this is, an adjustable part, over the adjusting means can be influenced. This adjustable part can be flexible and / or articulated connected to the remaining part of the cam be, which simplifies the assembly of the furniture hinge.

at Such a preferred embodiment of the invention is about the change of the outside Curved track of the cam, for example via a an adjustable determination of the cam on the hinge lever, the tension exerted by the traction means and thus their modified effective component. This causes one hand a change in the tensile force applied to the point of application, At the same time a change of the corresponding effective Component of traction.

In the drawing are generally equivalent parts with matching Reference numbers provided.

In 1 an inventive piece of furniture is disclosed, which is designed as a front panel furniture part 1 having. 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 , as well as a back 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 of in 2 closer explained lever mimic the furniture hinge or furniture fitting on.

The furniture hinge according to the invention comprises in the in 2 illustrated embodiment one on the furniture part 1 arranged mounting arm 5 on which a hinge lever 6 is hinged. The hinge lever 6 is about a rotary or pivot axis 7 pivotable. On the furniture part 1 opposite end of the mounting arm 5 is another hinge lever 8th hinged, which in turn about a further pivot axis 9 pivoted. The rotary or swivel axes 7 and 9 make up together with the joints 10 a four-joint system, by which the movement of the front door or the furniture part 1 is forced. As energy storage is a pressure cylinder 11 used, on the one hand like the swivel axes 7 and 9 movable on the side wall 12 is set and on the other hand via a slotted guide 13 , in turn, around an axis 14 is pivotable on a drawstring 15 acts. The drawstring 15 forms together with the slide guide 13 and the impression cylinder 11 a general with 16 numbered tensile and / or pressure force transmission means.

The drawstring 15 with the tensile force direction KR is pivotally mounted on the hinge lever 6 arranged pull lever 17 with the hinge lever 6 connected. An adjusting device designed as an eccentric 18 this serves to set one of the energy storage 11 over the slide tour 13 and the drawstring 15 on the hinge lever 6 applied torque, by means of an adjustable or variable lever arm KL, which is perpendicular to the drawstring 15 with the traction force KR through the center of the pivot axis 7 is created.

For example, if the in 2 shown eccentric rotated by 90 ° counterclockwise, the pull lever pivots 17 also counterclockwise and the impression cylinder 11 is becoming stronger compressed. Consequently, the front door or the furniture part 1 held in its closed position with a greater force. 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 may be the appropriate section as an extension of the drawstring 15 be flexible, resulting in an additional change in torque. In this case, the flexibility can be chosen so that this flexible part of the drawstring 15 at least partially around the eccentric 18 sets.

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 3 has the hinge lever unit 16 one on the hinge lever 6 arranged cam 19 on, which is more divided and next to a base part 20 a now by means of a trained as a screw actuator 18 adjustable part 21 includes. this part 21 is on two sides of the base part 20 guided and points in the direction of an elastic outer web 22 in the 3 differently shaped surface. By pushing out the adjustable part 21 , which is also referred to as an extendable plunger with an outer curved path, in the left direction in the figure and thereby changing the elastic web 22 the cam receives a different circumferential shape, so that a running on this cam tension band relative to the pivot axis 7 another torque on the pivot lever 6 exercises as in the non-extended and in the 3 shown (outer) shape of the cam 19 ,

At least part of the peripheral shape of the cam is thus opposite the pivot axis 7 changeable, resulting in by the between the articulation point of a tension band on the outer peripheral surface varying distance and the resulting tension between the attack point and pivot axis other levers and corresponding torques on the swing arm or hinge lever 6 result.

In the following figures are still 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 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 lies.

In the 4a is the cam 19 in the figure plane around the adjusting means 18 and pivotable by this fixable. A double arrow 23 indicates the direction in which the cam is located 19 can adjust and then according to the in the figures by 24 numbered curved track relative to the pivot axis 7 changes, resulting in the corresponding lever and the torque, which is different from the weight of the furniture part 1 superimposed exerted torque varies.

According to the double arrow 23 of the 4a describe the double arrows 23 of the 4b and 4c the displaceability of the cam 19 along the illustrated link guide 18 . 19.1 , by means of which the cam 19 opposite the hinge lever 6 is mobile.

A substantially based on the same principle of action, via an actuating means 18 variable cam 19 with an adjustable part 21 is in the 5a , b, c, 7 . 8th . 9 and 10 shown in which are those of a drawstring 15 touched cam track changes. The comparison of 5a to c clearly shows the extent to which the force application point 25 (KA) with respect to the rotary / pivot axis 7 changes. The adjustable part 21 Here is a film hinge or an elastically configured part of the cam with the fixed to the hinge lever 6 associated base part 20 connected.

In the 7 illustrated variant of the cam 19 has one in the cam 19 integrated screw, over which likewise the radius of the in the 7 shown left outer part of the curved path changes. The same applies to the 8th and 9 in which the variable, adjustable part 21 the cam 19 by means of a relative to the hinge lever 6 fixable base adjustable eccentric as adjustment 18 is variable. 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 10 a variant of the cam is shown, in which two adjusting means 18 the curve or circumferential path respectively in different Areas can change. While the closer to the rotation axis 7 located screw 18 has a greater influence on the maximum tensile force, the lower screw is used 18 amplifies a variation of the torque curve during the movement.

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

In the 11a to g in turn is a pivotable on the hinge lever 6 arranged cam 19 revealed in the case of more parts 27.1 and 27.2 respectively. 27 the cam 19 can be kept variable. Here too, the torque acting on the furniture part can be changed during the pivoting process.

In particular, closer to that 1 . 2 . 5a to 5c such as 7 . 8th . 9 . 10 such as 12a to 12c can be seen, is in the embodiment shown as a tension element a drawstring 15 provided in a slide guide 13 attacks one end ( 2 ) and at the other end to a pull lever 17 is attached. During the movement of the door in the open position, the cam is 19 with around the pivot axis 7 pivoted, whereupon the pulling direction KR and the lever arm KL change. This is closer 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 essentially in the starting position ( 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 z. B. a spring or the slotted guide 13 that the drawstring 15 in the direction of the arrow 15.1 draws. In 12a the closed position of the furniture part to be pivoted is shown. If this now be swung in the direction of the arrow P, the hinge lever arrives 6.1 and that with this swiveled end of the drawstring 15 in the position in 12b is shown. During the movement phase, the tension band exerts on the furniture part to be swiveled or on the hinge lever 6 a force that 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 12c is indicated. Here is the hinge lever 6 and with him the hinge lever 6.1 pivoted so far upwards that now the pulling force KR of the drawstring 15 so on the lever arm 6.1 acts, that a moment is generated, which either - taking into account the weight of the pivoting 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 adjusted 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 13 is shown in two graphs, how the torque is adjustable. Shown by the solid line is the required force-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 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 14a , b, c shown embodiment of the invention comprises the adjusting one on the lever 6 fixed bolt 31 that during the movement phase, which through the 14a , b, c is clarified, along with the lever 6 around the pivot axis 7 pivoted.

By pivoting the bolt 31 this arrives in the in 14b shown investment position with the drawstring 15 and press this in the direction of the printing cylinder 11 ,

The hinge lever 6 pivots this far, until a balance between the by the weight of the furniture part and the drawstring 15 caused and over the bolt 31 and the point of attack 25 on the swivel arm 6 achieved moments.

The 15a , 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 transfer of the resulting forces by means of the drawstring 15 this comes with the bolt 31 in the 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 pivot with, to a deflection of the tensile forces around the bolt 31 so that these starting from the point of attack and looking at the pivot axis 7 develop an optimal moment of action. This moment of action can be as desired by arranging the bolt and shape of the cam 19 be adjusted so that, for example, the pivoting movement is supported or favorable leverage for a rest position of the furniture part can be created.
