Abstract

The holder has safe-deposit box (16). The holder is movable between closing position (18) of a safe-deposit box into a furniture body (12). The two independent pressure accumulators (28,36,37,29,43,44) are assigned to the corpus side end region of the operating lever (24). The opening motion of the furniture flap supports an energy accumulator predominantly and does not exert swivel movement, in a swivel area of the clamping position up to a dead center position. The other energy accumulator exerts clamping force particularly in the swivel area of the closing position up to the dead center position.

Description

The The invention relates to a flap holder for a furniture flap, between a a cabinet compartment in a furniture body occlusive closed position and an upwardly movable open position is adjustable, with at least one adjusting lever, which locates on the one hand via a pivot axis on the furniture body and on the other hand on the furniture flap is articulated.

A flap holder of this kind is for example from the DE 10 2004 019 785 A1 Known, wherein there disclosed flap fitting at the first adjusting axis facing end portion of the actuating lever has an eccentric to the first control axis, the movement behavior of the flap force moderately influencing control curve, which is associated with a held by a spring device against the control cam pressure piece, so that the pressure piece of a the pivoting position of the actuating lever dependent pivoting moment exerts on the control lever. In such flap fittings can be achieved by a suitably selected course of the control cam that holds the flap on its way from the closed position to the open position practically in any intermediate position by itself. Accordingly, the force to be applied by the user for opening and closing is small. The cam is contoured such that in a sub-dead center by the pressure piece a holding the flap in the closed position clamping force is exercised.

at such flap holders, the spring force is the flap weight adapted, that is at a heavy furniture flap the spring device must apply a high spring force so as to an acting against the high flap weight large swivel torque in the opening direction to be able to raise. Since the control curve is contoured in such a way that after over- or Falling below the dead center, a change of the pivoting moment takes place, the spring force of the spring device also affects the locking force in the closed position out. The furniture flap is therefore also with a relatively large locking force in the closed position held by the user when opening up to the dead center must become.

task The invention is a valve holder of the type mentioned to create, in which the flap on the furniture acting locking force regardless of in the opening direction acting force is.

These The object is achieved by a flap holder having the features of independent claim 1 solved. Further developments of the invention are shown in the subclaims.

Of the inventive flap holder is characterized by the fact that the body side end of the Control lever at least two independently acting energy storage are assigned, of which a force storage mainly the opening movement the furniture flap supports and in a pivoting range from the closed position to a dead center position exerts almost no pivoting moment, while the other energy storage especially in the pivoting range of the closed position until the dead center exerts a closing force.

In a further development of the invention, a control disk is assigned to the body-side lever end of the actuating lever, with a first curve region, which is assigned a first pressure element held against the curve region by a first spring device, the first curve region having a curve section eccentric to the pivot axis, so that when driving over wherein the control disk has a second curve area, to which a second pressure piece held by a second spring device against the second curve area is assigned, the second curve area having an eccentric curve section to the pivot axis such that, when the second pressure piece is passed over, a pivoting moment acting in the closing direction is exerted on the furniture flap, wherein the first curve portion 28 a circular arc-like curve section 34 and the second curve area 29 a circular arc-like curve section 35 or another eccentric, when driving over the second pressure piece 44 has a curve acting in the opening direction pivoting moment, curve portion, and wherein in the closed area of the furniture flap 17 the first curve area 28 with its arcuate curve section 34 on the first pressure piece 37 and the second curve area 29 with its eccentric curve section 33 on the second pressure piece 44 abuts and when opening the flap then to the closing area of the first curve area 28 with its eccentric curve section 32 on the first pressure piece 37 and the second curve area 29 with its arcuate curve section 35 or its further eccentric curve section on the second pressure piece 44 is applied.

In the eccentric curve sections so pivoting moments can be transferred to the furniture flap, while in the circular arc-like curve sections substantially no pivoting moment is initiated. Thus, for example, while the eccentric curve section is "in action" in the first curve area and a pivoting moment is exerted by means of the associated first pressure piece, the second curve area can be used the circular arc-like curve section or the further eccentric curve section "in action", so that essentially no pivoting moment or an additional pivoting moment acting in the opening direction is exerted here. For the force in the opening direction, therefore, the spring force of the first spring means and the contouring of the first curve area may be responsible, if necessary by supporting the second spring means, if the second pressure piece is in the further eccentric curve portion, while independently for the locking or closing force in the closed position is responsible only the spring force of the second spring device.

at a development of the invention, the two curve areas formed on two opposite peripheral regions of the control disk.

It is possible, in that at least one of the two curved areas is assigned one of the open positions End stop for the assigned pressure piece is provided. This prevents the furniture flap over the Open position can be further pivoted. In preferred Way is on both the first and the second curve area respectively an end stop provided. The end stop can be, for example be formed by a trough-like depression in the control disk. Of course it is also possible instead of forming the recess a projection on the control disk.

The both spring devices can on the one hand stationary on a furniture body mounted on the fitting plate and then again a first and second, the first and second pressure piece bearing Power transmission element be coupled with the control disk. The first power transmission element For example, can be mounted by a pivotally mounted on the fitting plate Pressure piece carrier formed become. The second power transmission element is in a preferred manner by a pivotally mounted on the fitting plate mounted pivot lever formed.

Around a violent striking the furniture flap to the cabinet body when retracting into the closed position can prevent, in the area of the body end of the lever Adjusting lever a damping device be provided. In a particularly preferred manner is the attenuator between the pivot lever and the fitting plate and can through the pivoting movement of the pivot lever are actuated. The damping device can be arranged stationary on the pivot lever and an actuating part have that on a formed on the fitting plate actuating projection depressed can be.

at a development of the invention is the control disk of two the body-side lever end on both sides comprehensive disc parts educated. Alternatively it is possible to form the control disk in one piece, in which case the adjusting lever can be arranged left or right of the control disk.

One preferred embodiment The invention is illustrated in the drawing and will be described below explained in more detail. In show the drawing:

6 a perspective view of the valve holder of 5 without cupboard and furniture flap.

The 1 to 6 show a preferred embodiment of the valve holder according to the invention 11 , The flap holder 11 is on a cabinet, in particular wall unit, arranged, which is attached hanging in height on a building wall. The furniture 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 ceiling wall 15 and a back wall and includes a limited by these walls cabinet 16 , The front of the cabinet compartment 16 is a furniture flap 17 assigned in their out 1 resulting closed position 18 occupies a vertical position and the cabinet compartment 16 closes. The furniture flap 17 can from this closed position 18 in one the access to the cabinet compartment 16 gestattende open position be adjusted, the opening movement on the in the 3 and 5 shown intermediate positions upwards takes place. The furniture flap 17 will be exemplified below with reference to a two-piece furniture flap 17 described, which could also be referred to as a folding flap. Of course, the flap holder according to the invention 11 also in connection with a one-piece furniture flap 17 be used.

The furniture flap 17 is, as mentioned above, bisected by way of example and is of an upper flap portion 19 and a lower flap part 20 formed on a hinge axis 21 are hinged together. The hinge axis 21 is usually of two each at one of the two lateral end portions of the furniture flap 17 arranged hinges 22 educated. The hinge 22 can one at the top flap part 19 to be fastened upper hinge part and one at the lower flap part 20 having to be fastened lower hinge part, by means of a hinge axis 21 forming hinge pin or the like are hinged together. The two hinge parts can on the cabinet compartment facing inside the flap parts 19 . 20 be attached. The hinge axis 21 can close the gap between the two flap parts 19 . 20 or be arranged with a certain distance above or below the joint.

The upper flap part 19 is still around a hinge axis 23 swiveling on the furniture body 12 stored. This hinge axle 23 is preferably on the ceiling wall 15 of the furniture body 12 ,

In the closed position, the lower flap part closes 20 to the bottom of the upper flap part 19 in extension of this, so that the two flap parts 19 . 20 are coplanar with each other. When transferring to the open position, the two flap parts lead 19 . 20 opposing pivoting movements, in which the upper flap part 19 from the cabinet compartment 16 and thus from the furniture body 12 pivots away while the lower flap part 20 from his to the upper flap part 19 coplanar position about the hinge axis 21 to the cupboard compartment 16 and thus to the furniture body 12 pans out, leaving the furniture flap 17 folded, so to speak.

At least one of the two lateral end portions of the cabinet is a lever 24 arranged, on the one hand via a pivot axis 25 stationary on the furniture body 12 and on the other hand on the furniture flap 17 , in particular at the lower flap part 20 is articulated. The body-side lever end 26 of the control lever 24 is in exemplary assumption a control disk 27 assigned.

The control disc 27 has two mutually opposite peripheral areas of the control disk 27 located curve areas 28 . 29 , The control disc 27 is with the lever 24 motion coupled, that is when pivoting the control lever 24 will also be the control wheel 27 pivoted with. For this purpose has the control disk 27 two disc parts 30 . 31 the left and right of the control lever 24 attached to this, the lever 24 so in their midst take. Alternatively, a one-piece control disc can be used. The two curve areas 28 . 29 each have an eccentric curve section 32 . 33 and at least the first curve area 28 a substantially subsequent circular arc-like curve section 34 , According to the preferred embodiment also has the second curve area 29 a circular arc-like curve section 35 , The function of the curve sections 32 to 35 will be explained in more detail below.

The first curve area 28 is a via a first spring means 36 against the first curve area 28 held first pressure piece 37 assigned. The first spring device 36 is on the one hand articulated to one on the side wall 13 mounted fitting plate 38 articulated and on the other hand articulated with a first power transmission element 39 in turn, in turn, about a pivot axis 40 swiveling on the fitting plate 38 is stored and the first pressure piece 37 wearing. The first spring device is exemplified here in the form of a gas spring 36 shown. Alternatively, a helical compression spring would be used. The first pressure piece 37 is formed by a rotatably mounted on the power transmission element roller on which the first curve area 28 rolls along. The gas spring 36 can via adjusting means along the force transmission element 39 be stored adjustable. As adjusting can according to the DE 10 2004 019 785 A1 for example, one on the first power transmission element 39 in adjustment 41 extending adjusting spindle and rotatably mounted in its longitudinal direction. The gas spring 36 can sit on the adjusting spindle and be in threaded engagement with this. Twist the adjusting spindle 42 by means of a suitable tool, such as a screwdriver, the gas spring moves 36 along the adjusting spindle. As a result, the change on the first power transmission element 39 existing leverage ratios and thus that of the first power transmission element 39 about the role 40 on the lever 24 applied swivel moment.

The second curve area 29 is a through a second spring means 43 against the second curve area 29 held second pressure piece 44 assigned. The second pressure piece 44 sits on a second power transmission element in the form of a pivot lever 45 which is about a pivot lever pivot axis 46 swiveling on the fitting plate 38 is stored. The second pressure piece 44 is also formed as a role, where the second curve area 29 when pivoting the control lever 24 rolls past. The second spring device 43 on the one hand is stationary on the fitting plate 38 attached and on the other hand with the pivot lever 45 connected. The second spring device is exemplary in the form of a helical tension spring 43 shown, the pivot lever 45 together with the second pressure piece 44 in abutment on the second curve area 29 draws. The swivel lever 45 also has an over the circumference of the fitting plate 38 beyond the end section 47 , on which a damping device in the form of a damping cylinder 48 sitting. The damping cylinder 48 has a cylinder housing 49 who is at the end of the game 47 of the pivot lever 45 is attached and when pivoting the pivot lever 45 mitverschwenkt can be. In the cylinder housing 49 is an actuating part in the form of a control piston 50 guided linearly displaceable. The adjusting piston 50 acts with a on the fitting plate 38 trained nose-like actuating projection 51 so together, that during the retraction movement of the furniture flap 17 in the closed position 18 the actuating projection 51 for contact with the actuator piston 50 comes and this in the cylinder housing 49 pushes in, whereby the retraction is damped.

In the closed position 18 the furniture flap 17 is the second pressure piece 44 in a recording recess 52 at the end of his eccentric curve section 33 while the first pressure piece 37 at the opposite first corner area 28 at the circular arc-like curve section 34 is applied. In this situation, by the first pressure piece 37 through the system at its arcuate curve section 34 essentially no pivoting moment on the adjusting lever 24 exercised, one could say, the first pressure piece 37 is ineffective. The second pressure piece 44 on the other hand exercises by abutment on the eccentric curve section 33 a pivoting moment in the closing direction, that is the furniture flap 17 is locked with the furniture body 12 pressed. When opening the furniture flap 17 now passes first the eccentric curve section 33 of the second curve area 29 the second pressure piece 44 , which still gives a locking force on the furniture flap 17 is exercised because at the opposite first curve area 28 still the arc-like curve section 34 in contact with the first pressure piece 37 is, so that here no pivoting moment is initiated. The locking force is even greater because of the pivoting moment co-determining lever arm - vertical distance between the normal by the tangent at the contact point between the pressure piece 44 and curve section 33 and pivot axis 25 - gets bigger at first.

In 3 the reversal point or the dead center position is shown. In this position, there is the second pressure piece 44 in abutment with the transition between the eccentric curve section 33 and the arcuate curve section 35 , According to a further embodiment, not shown, in the second curve area to the eccentric cam section another eccentric curve section close, which is designed so that when passing through the second pressure piece acting in the opening direction additional pivoting moment is exerted on the furniture flap. The generated in the first curve area swivel torque in the opening direction is thus supported. It is possible to use the other eccentric curve section on the second curve area as a trough-like depression 55 to train downhill. This transition between eccentric and kreisbogenartigem or other eccentric curve section 33 . 35 Here is an example of a hump 53 shown. The second pressure piece 44 essentially exerts no pivoting moment on the lever, so is ineffective or exerts a pivoting moment in the opening direction. At the same time is the first pressure piece 37 at the opposite first corner area 28 also at the transition between its arcuate curve section 34 and its eccentric curve section 32 , In principle, however, it would also be possible for the first pressure piece 37 already in abutment with its eccentric curve section 32 is so that when driving over the pressure pieces 37 . 44 not reached the two dead center simultaneously.

Will the furniture flap 17 now opened even further, the arcuate curve section passes over 35 or the further eccentric curve section on the second curve area 29 the second pressure piece 44 whereby it becomes ineffective, so to speak, and essentially no moment is introduced or a moment is generated in the opening direction, while at the opposite first curve area 28 the eccentric curve section 32 the first pressure piece 37 overruns. There is then a swivel torque on the lever 24 initiated and although in the opening direction of the furniture flap 17 , This pivoting moment counteracts the flap weight, so that the opening of the furniture flap 17 is relieved. By appropriate contouring of the eccentric curve section 32 at the first curve area 28 and possibly the other eccentric curve section on the second curve area, it is also possible that the furniture flap 17 remains in any open position. The opening movement of the furniture flap 17 is determined by En suggestions in the form of trough-like depressions 54 . 55 on the one hand at the end of the eccentric curve section 32 of the first curve area 28 and on the other hand at the end of the circular arc-like curve section 35 or another eccentric curve section of the second curve section 29 specified.

When closing the furniture flap 17 reverse operations occur. The eccentric curve section 32 of the first curve area 28 passes over the first pressure piece 37 in the reverse direction, while venbereich at the opposite second cure 29 the arcuate curve section 35 or the other eccentric curve section the second pressure piece 44 overruns. As long as the first pressure piece 37 still in abutment with the associated eccentric curve section 32 is still exerted a pivoting moment in the opening direction, there on the opposite second curve area 29 the second pressure piece 44 in contact with its arcuate curve section 35 or the other eccentric curve section. The reversal of the pivoting moment then takes place again when the dead center positions between the respective eccentric and circular arc-like or other eccentric curve sections are exceeded 32 to 35 , From here is namely the first pressure piece 37 again in abutment with its arcuate curve section 34 while the second thrust piece is in abutment with its eccentric cam section 33 is, so that a pivoting moment is exerted in the closing direction.

Generalizing is to be noted that the body-side end portion of the actuating lever 24 at least two independently acting energy storage 28 . 36 . 37 . 29 . 43 . 44 are assigned, of which a force storage 28 . 36 . 37 mainly the opening movement of the furniture flap 17 supports and in a swivel range from the closed position to a dead center almost no pivoting moment exerts, while the other power storage 29 . 43 . 44 especially in the swivel range from the closed position to the dead center exerts a closing force.
