Description

Opening and/or closing device for furniture

Technical Field

The invention relates to an opening and/or closing device for furniture in order to accelerate, brake and/or hold a movable furniture part relative to a furniture body, having a mounting element which can be fixed to the movable furniture part or the furniture body and on which an actuator is held via an adjusting mechanism, wherein the actuator can be coupled to the mechanism for accelerating, braking and/or holding and can be adjusted in a first direction relative to the mounting element via a first adjusting element.

Background

EP 2266436B 1 discloses an opening and/or closing device for a pushing element, which can be locked in a closed position via a locking mechanism. For this purpose, a locking lever is provided on which a locking mechanism is arranged such that, in the case of a stack-arranged pull-out pushing element, only one of the pushing elements can be pulled out of the furniture body in each case. For this purpose, each pushing element has an actuator which can be coupled to the locking mechanism. Alignment of the actuator with the locking mechanism is essential for smooth operation without error. In this regard, the locking mechanism includes an adjustment element to adjust the depth position such that the position of the front panel is adjustable relative to the furniture body. No possibility for further adjustment is provided.

AT 14959U 1 discloses a pull-out latch for locking a drawer when one of the drawers has been moved to an open position. A catch member is provided on the locking device and is provided on the adjustment mechanism to align the catch member during assembly. Therefore, assembly is relatively complicated and alignment of the respective latching parts is already required during assembly. Although the latch member is pivotally attached to the panel, it cannot move during adjustment.

Disclosure of Invention

It is therefore an object of the present invention to provide an opening and/or closing device for furniture, which allows a flexible alignment of an actuator coupled to a mechanism for acceleration, braking and/or retention.

This object is achieved by an opening and/or closing device having the features of claim 1.

In the opening and/or closing device according to the invention, the actuator is connected to the mounting element via an adjusting mechanism, the actuator being adjustable in a first direction relative to the mounting element via a first adjusting element, and the adjusting mechanism comprises an actuator carrier on which a second adjusting element is arranged for adjusting the actuator relative to the mounting element in a second direction at an angle to the first direction. As a result, the actuator can be adjusted in two different directions relative to the mounting element via at least two adjustment elements, which facilitates the alignment of the actuator and can compensate for assembly tolerances during the assembly of the furniture.

Preferably, the housing is adjustably held on the mounting element, on which housing a third adjustment element is provided for adjusting the actuator relative to the mounting element in a third direction at an angle to the first and second directions. This allows the actuator to be adjusted in three different directions relative to the mounting element, so that depth adjustment, height adjustment and lateral adjustment can be performed on the actuator. Thus, the three adjustment elements can adjust the actuator in three directions, each of which is vertically aligned with one another.

In a preferred embodiment, the actuator is fixed to or integrally formed with a strap that is slidably retained on the actuator carrier. The strap may be longitudinally oriented perpendicular to an axial direction of a pin or protrusion coupleable to the driver. The actuators may be stably held and guided on the actuator carrier via the strip.

The actuator carrier preferably has receptacles for guiding the strip with actuators and slidably guides the actuator carrier along the housing. The housing is in turn displaceably held on the mounting element, so that the displaceable arrangement of the housing on the mounting element, of the actuator carrier on the housing and of the actuator on the actuator carrier can be adjusted in three different directions, the actuator carrier being held relatively stably on the mounting element after the adjustment.

In order to fix the mounting element in a stable manner, this can be designed as a mounting plate which is fixed to the movable furniture part or the furniture carcass, for example by means of fastening means, and on which guide means, for example guide strips, are provided for adjustable fixing of the housing. The housing may at least partially enclose the mounting element with an angled guide strip.

For a simple adjustment mechanism, the first adjustment element, the second adjustment element and/or the third adjustment element can be rotatably mounted. For this purpose, each of the adjusting elements can optionally be designed as an eccentric or as a worm drive. In order to securely fix the respective set position, at least one of the adjusting elements, preferably all of the adjusting elements, can be locked in the set position.

In order to achieve a particularly compact design of the adjusting mechanism, three receptacles can be formed on the housing, the adjusting element engaging and being rotatably mounted in each of the three receptacles. This allows the actuator to be positioned on the housing via three adjustment elements.

In furniture, a plurality of drawer elements arranged in a stack, such as drawers, movable shelves, containers, hanging file shelves or other devices, are preferably arranged on the furniture body, each of the drawer elements being coupled to the opening and/or closing device in the closed position. In this respect, a locking mechanism may be secured to the furniture body, which locking mechanism locks the other drawer elements in the closed position when one drawer element is opened. Therefore, assembly becomes easy if the actuator is fixed to each pushing element, preferably to the rear of the front panel, via the mounting element. However, the opening and/or closing means may also be used with other mechanisms, for example with retraction means, ejection means or damping means. Furthermore, the opening and/or closing device can be used not only with a pushing element but also with a sliding door.

Detailed Description

The piece of furniture 1 comprises a furniture body 2, on which furniture body 2 a plurality of front panels 3 of drawer elements 4 are arranged at openings, in the present embodiment in the form of tray-shaped drawers. In fig. 2, the piece of furniture 1 is shown without the furniture body 2 and the front panel 3. Two drawer elements 4 arranged one above the other are displaceably held on the furniture carcass 2 via a pull-out guide 7. The locking mechanism 6 comprises a vertical locking lever 5 to ensure that the remaining drawer elements 4 are locked in the closed position when the drawer elements 4 are pulled out.

Fig. 3 shows the drawer element 4 in the region of the locking mechanism 6. An adjustment mechanism 10 having a mounting element 11 is fixed to the drawer element 4 at the rear side of the front panel 3, the adjustment mechanism 10 adjustably retaining an actuator 13 on the mounting element 11. The actuator 13 engages in a receptacle of the locking mechanism 6 to lock in the closed position when the other pushing element is opened. In this case, the actuator 13 must be positioned precisely relative to the receptacle of the locking mechanism 6. The locking mechanism 6 can be locked by a lock 8 which prevents all drawer elements 4 from opening.

The adjustment mechanism 10 with the actuator 13 is shown in fig. 4A and 4B. It can be seen that the adjusting mechanism 10 comprises a housing 12, on which housing 12 a first adjusting element 15, a second adjusting element 16 and a third adjusting element 17 are arranged. Via these

adjustment elements

15, 16 and 17, the position of the actuator 13 relative to the mounting element 11 can be adjusted.

The design of the adjustment mechanism 10 is shown in detail in fig. 5A and 5B.

The adjusting mechanism 10 is held on a mounting element 11, which is designed as a mounting plate and has two openings for fastening means in order to fix the mounting element 11 to the rear of the front panel 3 or alternatively to the furniture body. The mounting element has laterally projecting guide strips 19, and a receptacle 23 is formed on at least one guide strip 19.

The adjustment mechanism comprises a housing 12 adjustably held on the mounting element 11. The housing 12 has two angled guide strips 20 on the side facing the mounting element 11, which engage around the guide strips 19 on the mounting element 11. For adjusting the housing 12 relative to the mounting element 11, a first adjusting element 15 is provided, which is rotatably mounted in a receptacle 21 on the housing 12. The adjustment element 15 has a cylindrical portion optionally with a latching element that cooperates with a latching receptacle on the receptacle 21 to latch the adjustment position. The adjusting element 15 also has a pin 22 which is off-centre at the ends and engages in a receptacle 23 on the mounting element 11. By rotating the first adjusting element 15, the housing 12 can be displaced in a direction parallel to the longitudinal direction of the guide strip 19.

An actuator carrier 33 is arranged in the housing 12, which is displaceable relative to the housing. The housing 12 is designed as a hollow body which is open on one side, whereby the actuator carrier 33 is enclosed and guided by the housing 12.

For adjusting the actuator carrier 33 in the housing 12, a second adjusting element 16 is provided, which is rotatably mounted in a receptacle 24 on the housing 12. The adjusting element 16 has a cylindrical portion 25, wherein optionally latching projections or other latching elements can be provided to latch the adjusting position of the second adjusting element 16 to the receptacle 24. The second adjustment member 16 also includes an eccentrically disposed pin 26 that engages a slotted opening 27 in an actuator carrier 33. Rotation of the second adjustment member 16 moves the actuator carrier 33 in a second direction relative to the mounting member 11, which is oriented perpendicular to the first direction by the first adjustment member 15.

The third adjusting element 17 is rotatably mounted on the housing 12 at a receptacle 30 which is arranged opposite the receptacle 24 for the second adjusting element 16. The third adjustment element 17 comprises a cylindrical portion 28 rotatably arranged in a housing 30 and having an eccentrically arranged projecting pin 29 engaging a slotted housing 32 on the strap 14 integral with the actuator 13. The cylindrical portion 28 of the third adjustment member 17 is thereby engaged through an opening 31 (e.g. an oval or rectangular hole) in the actuator carrier 33. By rotating the third adjustment element 17, the strip 14 with the actuators 13 can be displaced in a third direction relative to the actuator carrier 33, the third direction being aligned perpendicular to the first and second directions. Alternatively, the third adjusting element 17 can also be locked in the adjusting position.

In the embodiment shown, the actuator 13 is formed as a protruding pin, but it may have another shape, such as a fork-shaped element or a receptacle. The actuator 13 is formed integrally with the strip 14, on which a guide web 35 is formed on the opposite side, which guide web is guided in a strip-shaped guide 34 of the actuator carrier 33. Thus, the strip 14 is guided in a receptacle between two strip-shaped guides 34 of the actuator carrier 33, and the actuator carrier 33 is slidably guided in the housing 12. The housing 12 is in turn displaceably guided on the mounting element 11.

In fig. 6A to 6C, the first adjusting element 15 is shown in different positions. In the first position according to fig. 6A, the mounting element 11 is positioned with its left end face flush with the end edge of the housing 12. By adjusting the first adjustment member 15, the housing 12 is displaced relative to the mounting member 11, as shown in fig. 6B and 6C. In fig. 6C, an end position is shown, in which the mounting element 11 abuts against the wall of the housing 12 on the front side. Alternatively, the housing may have a front edge on each side.

In fig. 7A to 7C, the actuator 13 is shown on the housing 12, with the second adjusting element 16 arranged in different positions. In the first position according to fig. 7A, the actuator 13 is arranged in an upper end position. By rotating the second adjustment member 16, the actuator 13 is moved downwards relative to the housing 12 and the mounting member 11, as shown in fig. 7B, until the lower end position in fig. 7C is reached, in which the actuator 13 is positioned by rotating the adjustment member 16.

In fig. 8A to 8C, different actuating positions of the actuator 13 are shown when the third adjusting element 17 has been adjusted. In the position shown in fig. 8A, the actuator 13 is in a left end position relative to the housing 12. By turning the third adjustment element 17 (not visible in this view because it is located on the opposite side of the adjustment element 16), the actuator 13 is moved over the strip 14, whereby fig. 8B shows a middle position and fig. 8C shows an end position, in which the actuator 13 is located furthest away from the mounting element 11.

In the embodiment shown, the adjusting

elements

15, 16 and 17 are designed as rotatable parts with eccentric portions. Of course, other actuating mechanisms may be used for the adjusting

element

15, 16 or 17.

Furthermore, the adjusting mechanism with the actuator 13 can also be arranged on the retraction device or the ejection device for the movable furniture part instead of on the locking mechanism 6. The retraction device can retract the movable furniture part into the closed position by means of the energy store, while the ejection device can eject the movable furniture part out of the closed position after unlocking by means of the energy store.

The movable furniture part need not be designed as a drawer element 4 but can also be designed as a sliding door.
