Description

The present invention is a furniture driving device for a movable furniture flap, and includes an operating arm connected to the movable furniture flap, a main spring for applying a force to the operating arm, and moving the movable furniture flap from a closed position to an open position. A locking device for locking, a locking device for locking the opening device, and a locking device when abutting the movable furniture flap or the actuating arm at least in the closed position and when the movable furniture flap is over-pressurized in the closing direction The invention relates to a furniture drive device for a movable furniture flap comprising a trigger element that can be unlocked. The invention also relates to furniture having such a furniture drive.

Furniture flaps are used in many different ways. For example, Patent Document 1 discloses a high-level flap, a flap that can be folded upward, a flap that can pivot upward, and a lifting flap. In this case, in order to facilitate the opening operation, a so-called touch latch device (opening device) is arranged in the area of the furniture frame . When pressure is applied to the closed furniture flap, this causes the furniture flap to be ejected (released) in the opening direction. In this case, the opening device is arranged in the lower region of the furniture frame and acts directly on the furniture flap, and the ejector (release device) of the opening device contacts the movable furniture part only in the first ejection stroke. After the end of the ejection operation, the flap is supported in part by the main spring but must be lifted manually. In the embodiment shown in FIG. 3 of US Pat. No. 6,057,059, the trigger element does not abut against the furniture flap or the actuating arm, but is simply fixedly connected, and therefore must always be interlocked with the furniture flap or the actuating arm. . In other words, different types of latest technology are formed.

  Patent Literature 2 and Patent Literature 3 disclose the same general type of furniture driving apparatus or furniture as the present invention, which includes an actuating arm device and an ejection device.

  The disadvantage of these structures is that, especially in the case of high flaps, the ejection device can only open the furniture flap at a relatively small angle. This is often less than 5 degrees. This means that a relatively long opening operation of the furniture flap must still be performed automatically by the user. In order to increase the opening angle, it would be possible to manufacture the ejection device significantly longer. However, in this case, when the flap is opened, these ejectors protrude far, which is an obstacle to the use of the furniture, and also has a disadvantage that the aesthetics are adversely affected. Furthermore, if the flap is quite heavy, the ejection device (also referred to as TIP-ON) has the disadvantage that it does not have enough force to perform the ejection procedure. There is also a drawback that it is often difficult to match the spring force of the ejection device and the spring force of the main spring.

Accordingly, it is an object of the present invention to provide an improved furniture drive for moving furniture flaps that surpasses the state of the art described above. Specifically, it is an object of the present invention to make it possible for a user to use a movable furniture flap drive that eliminates the above-mentioned drawbacks and substantially increases open comfort.

The furniture drive having the characteristics of the classification part of claim 1, wherein the opening device is connected to the actuating arm via a connecting device and the opening force for opening the movable furniture flap from the closed position is unlocked This object is achieved by being able to be applied to the actuating arm via a connecting device by means of a released opening device. This has the advantage that the opening device no longer acts individually on the movable furniture flap, but in each case the actuating arm connected to the movable furniture flap is ejected in the opening direction. This means that a separate TIP-ON (chip-on) mechanism (push-open mechanism) is no longer required in the lower region of the furniture frame . Furthermore, the connection device allows direct force transmission from the opening device to the working arm.

In a preferred embodiment of the present invention, the trigger element can be loosely abutted against the movable furniture flap or the actuating arm. Thus, there is no need for a fixed connection between the trigger element and the movable furniture flap or actuating arm. If there is a fixed connection, the trigger element must be a complex and expensive structure so that the entire travel of the movable furniture flap or actuating arm can also be performed on each, so that the movable furniture flap is wide open. It seems inconvenient if it is done. Preferably, the trigger element is connected to the locking device, preferably via a transmission mechanism provided separately from the movable furniture flap. This transmission mechanism can be disposed along the side wall of the furniture frame to transmit the trigger action. The lower the trigger element is located in the furniture frame region, the better the registration of the movement of the movable furniture flap in the closing direction, which is already slight, is possible.

The opening device can itself be of any desired structure (for example with gas pressure storage means), but preferably the opening device acts on the actuating arm in the opening direction. It shall have. For this purpose, the open spring is preferably separated from the main spring. In this way, the furniture drive can be used flexibly for movable furniture flaps of different sizes and weights. In this way, the furniture drive can also be easily retrofitted to an already installed actuating arm device that already has a main spring.

In a further preferred embodiment, a locking device is operatively arranged between the opening spring and the connecting device, and in the locking position, it prevents transmission of force between the opening spring and the connecting device. This means that in this mechanism, the locking is performed between an opening spring acting in the opening direction and an actuating arm engaging the movable furniture flap. When unlocked, the spring force of the open spring can be deployed and can act on the actuating arm via the connecting device and thus on the movable furniture flap.

It is important that the opening force acting on the movable furniture flap is greater at least in the first part of the opening movement than the closing restraining force acting on the actuating arm in this first part. The origin of this closure deterrent can be the main spring and / or the inherent weight of the movable furniture flap itself. However, the main spring is preferably calibrated to keep the movable furniture flap neutral at all times. In other words, the movable furniture flap can be easily operated by the user, and as soon as the user releases his hand, the movable furniture flap remains in the released position.

A specific advantage over the state of the art resides in a larger ejection opening angle, the first part of the opening operation being between 0 ° and 15 ° in the opening angle of the movable furniture flap, preferably Up to 20 ° regardless of the height of the movable furniture flap.

In order to re-load the opening spring, it is assumed that the opening spring of the opening device can be stressed in the opening angle range of the movable furniture flap, ie outside the first part of the opening operation. As a result, when the movable furniture flap is closed, the user automatically applies a load to the spring of the ejection device. In this regard, it is preferable to apply stress to the open spring when the movable furniture flap is closed, preferably in the open angle range of 150 ° to 15 °, particularly preferably in the open angle range of 75 ° to 25 °. Shall be possible.

Preferably, the further opening device may not engage the movable furniture flap, but only the connecting device. This means that the opening device does not directly contact the movable furniture flap as in the state of the art, but deploys its action on the actuating arm indirectly via the connecting element. Indeed, the possibility that the open spring acts directly on the actuating arm should not be excluded. When the open spring acts directly on the actuating arm, the open spring and actuating arm form a connection device, but in terms of force transmission, it is more effective to interpose at least one lever forming the connection device. It is. The movable furniture flap is not considered as a connection device; rather, the opening device is connected to the actuating arm via a connection device that is separate from the movable furniture flap.

  More preferably, the connection device is provided separately from the trigger element between the opening device and the actuating arm. Certainly, the trigger element can be directly abutted against the actuating arm to detect overpressure, but the opening force is nevertheless not via this trigger element, but via a separate connection device. Is transmitted to the working arm. Thereby, the transmission of the opening force can be more efficient.

Particularly preferably, in one embodiment of the invention, the trigger element, the transmission mechanism, the locking device, the opening device and the connecting device are in the form of structural units. Therefore, the TIP-ON mechanism which is separated in the state of the art is structurally integrated directly into the furniture drive and connected directly to the remaining components of the structural unit, thus without going through furniture or movable furniture flaps Is done. Depending on the particular design configuration involved, this structural unit can be attached to the actuating arm device (including the main spring, lever assembly and actuating arm) via a mounting plate or can be retrofitted (FIGS. 1 to 12). Can also be integrated directly into the actuating arm device (see FIGS. 13 to 22).

In a preferred embodiment of the invention, in the closed position, the ejection lever of the opening device abuts the thrust lever of the connecting device, preferably via a pressure roller, and the ejection lever is locked to the opening device. When released, the thrust lever can be turned. Thus, in order to transmit force to the movable furniture flap, the thrust lever of the connecting device is further connected to the element of the lever assembly connected to the actuating arm via at least one connecting element, preferably via a connecting pin. And, preferably, it can be connected with a relationship of securely locking. In this case, the element (or actuating arm) need not be part of the lever assembly. Rather, it is also possible to replace a lever assembly known per se, for example as shown in patent document 2, with a device according to DE 202 2005 21541. The important point is that the opening force is transmitted via the connecting device to the corresponding element of the lever assembly or to the pressure roller controller.

It is also possible to improve the braking when the movable furniture flap is closed, by applying an outward stress on the ejection device (i.e. not in the final closing part as in the state of the art). This is achieved by a braking device acting on the movable furniture flap in the final closed position. In this regard, preferably, the braking device may act on the lever of the actuating arm device in the opening direction in the final part of the closing action.

  The embodiment according to the invention shown is basically two. According to the first embodiment, the touch latch mechanism can be attached to the side of a lever assembly which is known per se. The second modification is a form integrated with a lever assembly (actuating arm device).

A problem that often arises when triggering an opening device is how best and most reliably the overpressure action that triggers the opening device is detected. In the case of a movable furniture flap, this is most likely the lower end of the movable furniture flap because it is the place where the greatest turning motion occurs. However, this requires an expensive and complex structure that takes up space on the trigger element and in particular the transmission mechanism compared to the locking device.

In order to avoid this, it is possible to move the trigger means relatively close to the pivot axis. However, the closer the occurrence of the detection is to the pivot axis of the movable furniture flap, the correspondingly the trigger has to respond and set more sensitively and more accurately. This is difficult to handle due to the fact that tolerance is often required.

  Both of these variants have the disadvantage that the detection procedure requires a relatively large and heavy furniture drive and its main spring to be pressed.

To solve this problem in a furniture drive having an actuating arm connected to the movable furniture flap, the actuating arm has a two-part structure and is fixed to the movable furniture flap in the closed position of the movable furniture flap. It is assumed that the part is movable relative to the second part which is in motion connection via the lever assembly of the furniture drive (and thereby relative to the main spring). This is because when applying pressure to the movable furniture flap when in the closed position, it is not the entire lever assembly that has to be pressed against the main spring, only the indirect flap fitting is the first part of the actuating arm. It means that it is moved by.

For this purpose, it is particularly preferred that the trigger element, which can unlock the locking device when the movable furniture flap is over-pressed in the closing direction, is the first part of the operating arm in the closed position of the movable furniture flap. Shall abut. Also preferably, the two parts can be pivoted relative to each other, and a force storage means acting in an opening direction with respect to the first part can be arranged between the two parts. .

Further, the furniture as described in claim 16 is also claimed for protection. Basically, it should not be excluded that the movable furniture flap has a vertical pivot axis, or possibly an inclined pivot axis. Preferably, however, the movable furniture flap is pivotable about a horizontal pivot axis.

  Further details and advantages of the present invention will be described more fully hereinafter with reference to the detailed description which refers to the embodiments shown in the figures by way of example.

  In both embodiments, elements having the same reference number include substantially the same function.

FIG. 1 shows a furniture driving device 51, on the rear side is shown a lever assembly 57 (actuating arm device) attached to a mounting plate 62 and having an actuating arm 52 and a main spring 59, and on the front side is opened. Shown is a module plate 58 to which the device 10, connecting device 54 and locking device 17 are attached. Also shown is a transmission device 55 that transmits the action of the trigger element 53 activated (triggered) by the movable furniture flap 11 (not shown) to the locking device 17 via the housing 68 and trigger bar 69. In FIG. 1, the furniture drive 51 is shown in the closed position SS. FIG. 1 also shows the braking device 13 acting on the lever 72, which is fixed to the lever 65 of the lever assembly 57. The braking device 13 is not shown in the other figures relating to the first embodiment, but in contrast, it can be seen in the figures relating to the second embodiment.

  Compared to FIG. 1, in FIG. 2, the furniture driving device 51 is in the fully open position, and the operating arm 52 moves to that position via the main spring 59, boomerang lever 61 and levers 63, 64 and 65 of the lever assembly 57. . The element 56 of the lever assembly 57 is provided with a rectangular fitting hole 67. The connection pin 54 c engages in the hole 67 so as to be surely locked. The connection pin 54c is fixedly connected to the thrust lever 54a and penetrates and engages with the opening 60 in the module plate 58. All the operations of the thrust lever 54a and the entire lever assembly 57 are transmitted through the connection pin 54c.

  FIG. 3 again shows the connection pin 54c protruding through the opening 60 in the module plate 58. FIG. FIG. 3 also shows the cover portion 62a of the lever assembly 57.

  FIG. 4 is an exploded view showing a touch latch mechanism that can be fitted to the operating arm device. In this case, important components (parts) are denoted by reference numerals. Only a few bolts and other connecting components are without reference signs. The individual components / reference symbols will be described in more detail in the description of the opening operation described later.

The procedure related to the opening / closing operation of the first modification is shown in FIGS. In this case, FIG. 5 shows the key components of the touch latch mechanism in the closed position SS. The entire mechanism is connected to and covers the actuating arm device via the module plate 58. The operating arm device itself is fixed to the furniture frame 26 of the furniture 32 and is connected to the movable furniture flap 11 via the operating arm 52 and the flap fitting 66. In this closed position SS, the trigger element 53 abuts on the movable furniture flap 11. The lock pin 17e on the ejection lever 10a is held against the holding nose 17b of the lock device 17, thereby locking the ejection lever 10a. Stress is applied to the open spring 12 (compression spring). The pressure roller 10b connected to the ejection lever 10a contacts the thrust lever 54a. The pivot shafts 10g and 10o are in a fixed position with respect to the module plate 58, and the ejection pivot shaft 54e is the same. This also applies to the fixed turning shaft 17f. The lock springs 17c and 17d (tension springs) are released from stress.

Here, as shown in FIG. 6, if the movable furniture flap 11 moves the trigger element 53 to the left by overpressure in the closing direction SR, the movable furniture flap 11 is connected to the trigger element so as to be rotatable around the pivot axis 70. The trigger bar 69 is moved downward, and the lock lever 17a is tilted about the fixed turning shaft 17f so that the holding nose 17b of the lock lever 17a is disengaged from the engagement with the lock pin 17e of the ejection lever 10a. The turning movement of the lock lever 17a occurs against the spring force of the lock spring 17c.

As soon as the locking pin 17e is disengaged from the holding nose 17b, the locking of the opening device 10 by the locking device 17 becomes invalid and the opening spring 12 can be released from stress. Due to this stress release, the lever 10c of the lever mechanism of the opening device 10 is partially pushed away from each other, and specifically, the ejection lever 10a pivots about the pivot axis 10g. As a result, the pressure roller 10b is pressed against the thrust lever 54a, and the thrust lever 54a turns around the ejection turning shaft 54e. This pivoting motion is transmitted to the operating arm device (more specifically, its element 56) via the connecting pin 54c, further to its lever 65, and subsequently to the operating arm 52. The operating arm 52 is movable. The furniture flap 11 is moved in the opening direction OR, whereby the opening angle γ and the opening position OS are achieved. As shown in FIG. 7, the release spring 12 is completely released from stress and the variable position pivots 10e and 10f are located at a maximum distance from each other. The turning shaft 10f is connected to a displacement portion 10i that can be displaced along the spring guide 10d. Furthermore, the opening device 10 has a braking roller 10h. Stress is applied to the two lock springs 17c and 17d. In FIG. 7, the components forming the opening device 10, the connecting device 54 and the locking device 17 and their reference numbers are enclosed in parentheses.

From the position in FIG. 7, the movable furniture flap 11 is manually moved further in the opening direction OR to the position shown in FIG. 8, thereby further turning the connecting device 54. By this turning operation around the ejection turning shaft 54e, the tension cam 54d contacts the tension roller 10j on the upper lever 10c. By moving the flap 11 upward, the lock springs 17c and 17d can be released from the stress again, and the ejection lever 10a can be swung counterclockwise about the swivel shaft 10g. 10j maintains contact with the tension cam 54d while moving away. Further, the lock pin 17e approaches the holding nose 17b. In this case, finally, as shown in FIG. 9, the lock pin 17e latches in the region of the holding nose 17b of the lock lever 17a. . As a result, the lock lever 17a is pivoted again about the shaft 17f and the trigger element 53 is moved out of the housing 68. From this position, the opening device 10 is locked by the locking device 17.

As shown in FIG. 10, when the movable furniture flap 11 is further moved in the opening direction, the tension cam 54d is lifted away from the tension roller 10j, whereby the force between the connecting device 54 and the opening device 10 is increased. Is no longer transmitted.

In comparison, as shown in FIG. 11, when the movable furniture flap 11 moves in the closing direction SR, the tension cam 54d comes into contact with the tension roller 10j again. This can preferably occur in the open angle range Δ. By this movement, the upper lever 10c is pivoted about the shaft 10o via the tension roller 10j, and the displacement portion 10i is displaced along the spring guide 10d against the force of the opening spring 12, and thus the opening spring 12 is moved. Stress is applied, and thereby the variable position pivot shafts 10e and 10f move toward each other. In this case, the variable position turning shaft 10e is in a stationary position with respect to the module plate 58 by a locking action related to the ejection lever 10a via the lock pin 17e. Thereby, tensioning of the open spring 12 becomes possible.

Referring to FIG. 12, the tension roller 10j is moved to the end along the tension cam (control cam) 54d, so that the release spring 12 is completely stressed. Even if it further moves in the closing direction SR, no stress is generated in the open spring 12 from the position shown in FIG. 12 due to the cam shape of the tension cam (stress cam) 54d. As a result, from the open position of the movable furniture flaps 11 can pull device, presumably acts on the movable furniture flap 11. However, the weight of the movable furniture flaps 11 may also be assumed that the user is compensated for by the main spring 59 so that it can easily operate the closure of the movable furniture flaps 11. By this closing procedure, the movable flap 11 and the furniture drive 51 as a whole are moved again to the position shown in FIG. 5 and the triggering element 53 is overpressured in the closing direction SR, thereby moving the movable furniture flap. Eleven active ejections are caused by the actuating arm 52 along with the opening device 10. At the end of the closure portion, the braking device 13 acts on the lever 72 of lever assembly 57, thus braking the closing movement of the movable furniture flaps 11, thereby, quiet and gentle closing of the movable furniture flaps 11 are provided.

  FIG. 13 shows a second embodiment of the furniture driving device 51 according to the present invention in an assembled state. In this case, the opening device 10 and the connecting device 54 are integrated into the actual actuating arm device and fixed to the mounting plate 62 (not via the module plate 58).

  FIG. 14 is an exploded view of FIG. 13 where all important components are provided with reference numerals. Some secondary components, such as connection bolts, for example, have no reference number. However, it is possible to clearly explain the principle of operation without directly identifying these components by their reference numbers. In both FIGS. 13 and 14, the actuating arm 52 is shown in the closed position.

15 to 22 show the furniture driving device 51 without the furniture frame 26 and the movable furniture flap 11. However, the mounting arrangement is the same as that of the furniture driving device 51 according to the first embodiment.

In FIG. 15, the actuating arm 52 (and thus the movable furniture flap 11 not shown) is in the closed position SS. In this case, the trigger element 53 is in contact with the operating arm 52 or the movable furniture flap 11 itself. The trigger element 53 is connected to the transmission mechanism 55 via the pivot 70 located at a fixed position with respect to the mounting plate 62, in this case, integrally. The spring 71 (tension spring) acts on the transmission mechanism 55 so as to constantly move it around the pivot shaft 70 in the clockwise direction. The end of the transmission mechanism 55 is connected to the unlocking element 17h via a connection bolt 17i. The unlocking element 17h can be turned around the ejection turning shaft 54e. Similarly, the hinge lever portion 17g can be turned around the ejection turning shaft 54e. The other end of the portion 17g is connected to the lock lever 17a via a hinge lever bolt 17j. 17j, 17g and 17a are combined to form a hinge lever. Around the hinge lever bolt 17j, a lock spring 17d is arranged to push the hinge lever bolt 17j upward with respect to the ejection pivot shaft 54e and the holding nose bolt 17k. Referring to FIG. 15, the hinge lever bolt 17j is slightly above the imaginary line between the ejection pivot shaft 54e and the holding nose bolt 17k. Further upward movement of the hinge lever bolt 17j is prevented by the holding nose 17b of the lock lever 17a contacting the lock pin 17e. The lock pin 17e is disposed on the tension cam 54d. The tension cam 54d is connected on the one hand to the lock lever 17a via the holding nose bolt 17k, and on the other hand to the ejection lever 54a via the tension cam turning shaft 54f. The ejection lever 54a is attached so as to be pivotable about the ejection pivot shaft 54e. Further, the ejection lever 54a is connected to the connection lever 54b via an ejection bolt 54g. This is then connected to the element 56 of the lever assembly 57 via the connection pin 54c so that the movement of the element 56 and the ejection lever 54a is always consistent.

  The open spring 12 is fixedly connected at one end to the mounting plate 62 via the mounting element 10m. The other end of the open spring 12 is connected to the guide pin 10 n, and the guide pin 10 n is guided in the guide path 10 k in the mounting plate 62. The release spring 12 is also connected to the ejection lever 10a via the guide pin 10n, and the ejection lever 10a can pivot about a fixed pivot shaft 10g connected to the mounting plate 62. The ejection lever 10a has a pressure roller 10b located in a slightly lowered region between the ejection lever 54a and the tension cam 54d at the lower right end. In the closed position SS, the force of the opening spring 12 presses the tension cam 54d via the pressure roller 10b. As a further consequence, since a force is applied to the lock lever 17a via the holding nose bolt 17k, the hinge lever bolt 17j is in the closed position as long as it is allowed by the impact of the holding nose 17b against the lock pin 17e. Driven upward in SS.

Here, as shown in FIG. 16, if pressure is applied to the movable furniture flap 11 or the operating arm 52 in the closing direction SR, the trigger element 53 is also propelled in the closing direction SR and the transmission mechanism 55. Is pivoted about the pivot axis 70 against the force of the spring 71, so that, as a further result, the unlocking element 17h is rotated counterclockwise about the ejection pivot axis 54e via the connection bolt 17i. Moved. As a result, the unlocking element 17h comes into contact with the rear portion 17g of the hinge lever, thereby moving the hinge lever bolt 17j below the imaginary line between the ejection pivot shaft 54e and the holding nose bolt 17k. . This is also executed against the spring force of the lock spring 17d. As soon as the hinge lever bolt 17j moves below the imaginary line, the spring force of the release spring 12 no longer acts to lock onto the lock lever 17a and the holding nose 17b via the pressure roller 10b and the tension cam 54d. First, the hinge lever is moved against the spring force of the spring 17d.

As a result, the hinge lever moves to the fully pivoted position shown in FIG. In this position, the hinge lever bolt 17j is positioned clearly below the imaginary line between the ejection pivot 54e and the holding nose bolt 17k. Simultaneously with the turning operation to the inside of the hinge lever, the tension cam 54d is also turned clockwise about the tension cam turning shaft 54f, and in the figure, the left edge (cam portion) of the tension cam 54d and the thrust lever 54a is exactly overlapped. And they are designed to cover each other. Simultaneously with the turning operation to the inner side of the tension cam 54d, the pressure roller 10b also starts to move in association with the release from the release spring 12, whereby the thrust lever 54a is counteracted about the ejection turning shaft 54e. It is rotated clockwise. As a result, the open position OS shown in FIG. 18 is achieved, and the operating arm 52 has an open angle γ as shown in the figure. This opening action is performed by the connecting lever 54b, which is also moved by the pivoting movement of the thrust lever 54a and triggers the pivoting action of the element 56 of the lever assembly 57. As a result of the pivoting movement of the element 56, the lever 65 of the lever assembly 57 is moved to the right and the actuating arm 52 is opened together with the movable furniture flap 11. Looking at FIG. 18, the main spring 59 has already been released somewhat from the stress compared to FIG. The dead center in the main mechanism (actuating arm device having the main spring 59) is overcome by the ejection operation. The braking device 13 is no longer in contact with the lever 72 of the lever mechanism 57. The return spring 71 causes the transmission mechanism 55 to turn again about the turning shaft 70, whereby the trigger element 53 is moved again to the starting position (as in FIG. 15) in the same manner as the unlocking element 17 h. Yes.

As soon as the opening spring 12 is completely released from stress (as in FIG. 18), the movable furniture flap 11 is manually moved further in the opening direction OR. In this further operation, since there is no longer any spring force acting on the tension cam (stress cam) 54d from the opening spring 12 via the ejection lever 10a and its pressure roller 10b, the lock spring 17d is released from the stress, and the hinge The lever can be pushed to the position of FIG. In this case, the hinge lever bolt 17j is again disposed above the imaginary line between the ejection pivot shaft 54e and the holding nose bolt 17k, and the holding nose 17b contacts the lock pin 17e.

Here, if the movable furniture flap 11 is further moved in the opening direction (see FIG. 20), the tension cam 54d and the pressure roller 10b are disengaged to reach a complete opening position.

In FIG. 21, the movable furniture portion ( movable furniture flap 11) is moved in the closing direction SR, and the application of stress by the opening spring 12 is started in the opening angle range Δ. For stress application, the tension cam (stress cam) 54d locked by the lock lever 17a and the holding nose 17b contacts the pressure roller 10b over the stress application portion C, and pushes the release spring 12 through the ejection lever 10a. This is started by stressing this.

Such stress application is performed until the highest point of the pressure roller 10b tension cam (stress cam) 54d is reached and the state moves to the retracted portion E. Upon reaching this retracting portion E, the opening spring 12 can be released slightly from the stress (movement from FIG. 22 to FIG. 15), thus actively retracting the movable furniture flap 11 in the final closed position. This is because the connection lever 54b is actively rotated clockwise about the ejection turning shaft 54e so as to give a retracting action to the operating arm 52 by passing through the high point of the tension cam (stress cam) 54d. Means that. However, this stress release is performed only until the pressure roller 10b shifts to a recessed portion (concave portion) between the tension cam (stress cam) 54d and the connection lever 54b. As a result, the closed position SS as shown in FIG. 15 is obtained again. The advantage of the present invention is that in this retraction operation-in this case an active retraction operation-the braking device 13 allows the retraction operation triggered (triggered) by the opening spring 12 to thereby be movable furniture. It also provides a slow and gentle closure of the flap 11.

It is also noted that for both embodiments, a synchronization bar can be fixed, for example in the region of the ejection pivot axis 54e, which transmits the rotational movement to a preferably mirror-symmetrical lever mechanism on another side of the furniture frame 26. Should be.

FIG. 23 is an exploded view showing a two-part working arm 52. In this case, the second portion 52b of the actuating arm 52 is positively coupled or kinematically coupled to the lever assembly 57 (not shown in this figure) via the connection region 88. In other words, the operation of the second portion 52b of the operating arm 52 always leads to the operation of the lever assembly 57, and vice versa. Further, a displacement element 81 is disposed on the second portion 52 b of the operating arm 52, and the linear displacement of the first portion 52 a of the operating arm 52 via the displacement element 81 is rotated via the displacement knob 83. Is possible. Further, a pivot shaft 86 is also arranged in the region of the second portion 52b, and the two portions 52a and 52b can pivot with respect to each other along the pivot shaft 86 against the force of the force accumulating means 80. . A plurality of connection bolts 87 are shown in the region of the first portion 52 a of the operating arm 52. In the lower region of the first portion 52 a of the actuating arm 52, a contact area 82 for the trigger element 53 is shown, and a latch element 84 for attaching to the flap fitting 66 of the movable furniture flap 11 is also with a latch spring 85. It is shown.

  FIG. 24 shows the actuating arm 52 in the assembled state, with the contact area 82 emanating from the second portion 52 b of the actuating arm 52.

  FIG. 25 shows a cross section of the actuating arm 52 with the force storage means 80 (which may be in the form of a spring shock absorber, rubber shock absorber, etc.) in the release position.

Since the movable furniture flap 11 (not shown in FIG. 26) is fixedly connected to the first portion 52a of the operating arm 52, when the movable furniture flap 11 is pressed, first, the first portion of the operating arm 52 is displayed. 52a is moved with respect to the second portion 52b of the operating arm 52 against the force of the force accumulating means 80 (swivel operation).

  FIG. 27 shows a diagram corresponding to FIG. 25 in a state where the furniture driving device 51 is entirely in the closed position SS (this diagram also corresponds to FIG. 15). From FIG. 27 it can be seen that the first portion 52 a of the actuating arm 52 is in contact with the trigger element 53 via the contact region 82. The second part 52 b of the actuating arm 52 is securely connected to the lever assembly 57 and is thus acted indirectly by the main spring 59.

28 and 29 show that the trigger element 53 abutting at least the first part 52a by the first part 52a of the actuating arm 52 pushing the movable furniture flap 11 in the closed position SS is locked by the locking device 17. FIG. This indicates that the movable arm 52 can move with respect to the second portion 52b until the lock is released. Thereby, the opening force for opening the movable furniture flap 11 is applied to the movable furniture flap 11 from the second portion 52b of the operating arm 52 via the opening device 10 via the first portion 52a of the operating arm 52. Is possible. In other words, the opening device 10 can be triggered by pushing the movable furniture flap 11 and does not require manual operation against the inertia of the main spring 59 and the entire lever assembly 57. If anything, only the movement of the movable furniture flap 11 and the first part 52a of the actuating arm 52, which are in a reciprocal relationship with the trigger element 53, is necessary, so that the unlocking of the locking device 17 is transmitted. It can be performed via the mechanism 55.

In FIG. 29, a furniture driving device 51 for opening the movable furniture flap 11 (not shown) is shown correspondingly.

FIG. 30 shows a three-dimensional view corresponding to FIGS. 28 and 16 of the furniture driving device 51 in the overpressure closed position US. In this case, the first part 52a of the actuating arm 52 and its contact area 82 are moved by the operator pushing the movable furniture flap 11, so that the unlocking element 17h is triggered by the trigger element 53 via the transmission mechanism 55. The lock device 17 is moved downward so that unlocking occurs.

Accordingly, the present invention provides a furniture drive for the movable furniture flap 11 in which active and direct ejection of the movable furniture flap 11 is performed via the actuating arm 52 by over-pressing the movable furniture flap 11 in the closing direction SR. Device 51 is shown.
