Description

The invention relates to a furniture fitting for a movable furniture part, in particular for driving a flap, a door or a drawer, with a stop device which has at least one stop element which is used to specify a specific open position of the movable furniture part with a furniture body or a fitting part the fitting arranged counter-stop cooperates.

With furniture fittings for furniture flaps, end stops are used to set different open positions of the flap. To change the open position or the maximum opening angle of the flap, the end stop is exchanged, since in this case each end stop specifies a certain open position. Alternatively, it is known that the end stop is designed in the manner of an adjusting screw, with different opening positions being able to be specified by screwing in or unscrewing it to different degrees.

A furniture fitting is for example from the DE 20 2005 016 375 U1 known.

Exchanging one end stop for another to change the predefinable open position is complex. The setting of the open position by means of the adjusting screw is also time-consuming, since here there is a need to check after the setting process whether the set open position corresponds to the desired value.

The object of the invention is to create a furniture fitting of the type mentioned at the beginning with which different open positions of the movable furniture part can be preset in a simple and cost-effective manner.

This object is achieved by a furniture fitting with the features of independent claim 1. Further developments of the invention are presented in the subclaims.

The furniture fitting according to the invention is characterized in that the stop element has several stop surfaces that can be used to specify different open positions.

Different open positions can therefore be specified by one and the same stop element. An exchange of the stop element for another, as described above, is therefore not necessary. Furthermore, the currently used stop surface clearly corresponds to a specific open position or a specific opening angle of the movable furniture part. It is therefore not necessary to check the set opening angle, as described above in connection with the adjusting screw.

In a further development of the invention, the stop element can be positioned by means of adjusting means in different stop positions, in each of which a desired one of the stop surfaces can be used. The adjustment means allow the stop element to be repositioned quickly into other stop positions.

In a particularly preferred manner, the stop surfaces are formed by peripheral surface sections of the stop element.

In order to realize short repositioning paths of the stop element, the stop surfaces are expediently arranged adjacent to one another, in particular they adjoin one another.

According to the invention, the stop element has a base in the form of a polygon. The stop element is expediently designed in the manner of a plate, that is to say has a relatively small material thickness.

In a further development of the invention, the adjustment means have a pivot bearing, via which the stop element is pivotably mounted on a fitting part of the fitting between the different stop positions. The fitting part can, for example, be a cover plate of the furniture fitting, which serves to cover the remaining fitting parts.

According to the invention, holding means are provided via which the stop element is held in a fixed position in its set stop position. The holding means are expediently designed as latching means, the set stop position being held by latching a latching element with a latching opening.

It is possible to provide holding means which are designed separately from the adjusting means and which are activated after the desired stop position has been set or reached. However, it is preferred that the holding means, in particular latching means, are assigned to the adjustment means, the holding means, in particular latching means, also acting or being activated at the same time when the desired stop position is reached. In the case of holding means designed as a latching means, the latching element can therefore be used when the stop element is adjusted When the desired stop position is reached, simultaneously snap into the associated locking opening.

In a further development of the invention, the fitting is designed as a support arm arrangement with several support arms connected to one another in an articulated manner.

Expediently, a power drive that can be arranged on the furniture body is provided, which is connected to the support arm arrangement via a lever mechanism made up of several gear levers for introducing a force in the closing direction and, after passing a dead center, for introducing a force in the opening direction of the movable furniture part. In a particularly preferred manner, the stop element sits on the lever mechanism. This ensures that the stop element is arranged in the immediate vicinity of the force introduction, which prevents the support arms belonging to the support arm arrangement from being pushed through in extreme situations, for example loading the movable furniture part beyond the open position. The close proximity of the stop element and the introduction of force therefore has advantages and enables the entire furniture fitting to be more rigid.

The fitting part on which the counter-stop is seated is expediently formed by a gear lever of the lever mechanism.

In a further development of the invention, at least one damper, preferably a fluid damper, in particular an oil damper, is provided for damping the movement of the movable furniture part when it is moved into the closed position and / or extended into the open position.

The invention further comprises a piece of furniture with at least one movable furniture part, such as a flap, door or drawer, which is characterized by a furniture fitting according to one of claims 1 to 12.

the furniture fittings from Figure 1 , the furniture flap is in a third open position.

The Figures 1 to 4 show a preferred embodiment of the furniture fitting 11 according to the invention. The design and function of the furniture fitting 11 is explained in the following purely by way of example using a so-called flap fitting which is intended to drive a furniture flap 13 of a piece of furniture 10, on the one hand on a furniture body 12 and on the other hand on the furniture flap 13 is to be mounted. Instead of a movable furniture part, a Furniture flap 13 spoken. It is of course possible to use the furniture fitting 11 to drive a furniture cover, for example a furniture chest, a door, for example a refrigerator door or a drawer.

According to the preferred exemplary embodiment, the furniture fitting 11 is thus arranged on a piece of furniture 10, preferably a cabinet, in particular an upper cabinet, which is fastened vertically on a building wall. The furniture body 12 of the cabinet has opposite vertical side walls 14, of which only one is visible in the drawing, a bottom wall, a top wall 15 and a rear wall and contains a furniture compartment 16 delimited by these walls with a furniture compartment opening, the furniture compartment 16 optionally through a shelf (not shown) can be divided in height.

The front of the furniture compartment 16 is assigned the furniture flap 13, which in its closed position assumes a vertical position and closes the furniture compartment 16 ( Figure 1 ). The furniture flap 13 can be moved from this closed position into an open position allowing access to the furniture compartment after having covered a certain opening angle.

The furniture fitting 11 takes over the movable guidance of the furniture flap 13 between the closed and the open position.

The furniture fitting 11 has a first support arm 17 and a second support arm 18, each of which can be pivoted about first and second pivot axes 19, 20 on the furniture body 12 and on the other hand pivotable about first and second pivot axes 22, 23 on the furniture body 12 the furniture flap 13 attached holding part 24 are stored. The two support arms 17, 18 are each designed as toggle levers and each have a body-side and a flap-side support arm part 25a, 25b; 26a, 26b. The support arm parts 25a, 25b of the first support arm 17 and the support arm parts 26a, 26b of the second support arm 18 are each pivotably connected to one another via a connecting joint 27, 28. The two support arms 17, 18 are pivotably connected to one another via a connection by means of a further connecting joint 29. Overall, this results in an exemplary manner according to the preferred exemplary embodiment, a support arm arrangement in the form of a 7-joint arrangement. In principle, however, the invention could also be applied to a 4-joint arrangement.

The furniture fitting 11 has a self-tightening device with a power drive 30 for introducing a closing force in the closing direction and, after exceeding a dead center, for introducing an opening force in the opening direction on the furniture flap 13 is arranged. The power drive 30, in conjunction with a lever gear 31 made up of several gear levers, ensures self-tightening. The power drive 30 is expediently attached only on one side, that is to say on one of the two furniture fittings 11 which are located on the left and right on the side wall of the furniture compartment 16.

The power drive 30 is in the form of a spring accumulator. The spring accumulator has a base element 32 which is attached to the body-side fitting part 21 so as to be pivotable about a bearing axis 33. An adjusting slide 34 is held axially adjustable along an adjustment axis 35 on the base element 32. The adjusting slide 34 is by means of compression springs 36, which on the one hand against the base element 32 and on the other hand against the Support adjusting slide 34, acted upon with force in the direction of an extended position. So that the compression springs 36 do not bend transversely to the adjustment axis 35, each compression spring is assigned a mandrel (not shown) on the setting slide 34, which dips into the coils of the compression springs 36 designed as helical springs and protects the respective compression spring 36 from bulging laterally.

The power drive 30 is connected via the lever mechanism 31 to the support arm arrangement, that is to say to the 7-joint arrangement according to the exemplary embodiment. The lever mechanism 31 comprises a rocker-like force deflection lever 37 which is mounted pivotably about a deflection lever pivot axis 38 on the body side. The reversing lever pivot axis 38 divides the force reversing lever 37 into a first lever arm 39a, which is assigned to the power drive 30, and a second lever arm 39b facing away from it. On the first lever arm 39a there is a coupling member 40 in the form of a coupling bolt on which the adjusting slide 34 of the power drive 30 engages, whereby the force exerted by the power drive 30 is introduced onto the power deflection lever 37. The coupling member 40 thus represents the force introduction interface between the power drive 30 and the force deflection lever 37. On the second lever arm 39b of the force deflection lever 37 there is a push rod 41 which is pivotably connected to the force deflection lever 37 via a push rod joint 42. At the end of the push rod 41 facing away from the force deflection lever 37, a second push rod joint 43 is provided, via which the push rod 41 is pivotably mounted on the support arm arrangement.

The furniture fitting 11 also has a stop device 44, which has at least one stop element 45, which is used to specify a specific open position of the furniture flap 13 with one on the furniture body 12 or on a fitting part of the furniture fitting 11 arranged counter-stop 46 cooperates. The stop element 45 has several stop surfaces 47a, 47b, 47c that can be used to specify different open positions. According to the preferred embodiment, the stop element has three different stop surfaces 47a, 47b, 47c, which are each formed by peripheral surface sections of the stop element 45. Of course, more or fewer than three stop surfaces are also conceivable.

As shown in the figures, the stop element 45 is designed as a flat part, the stop surfaces 47a, 47b, 47c being formed by peripheral surface sections of the stop element 45. According to the exemplary embodiment described, the stop surfaces 47a, 47b, 47c are arranged adjacent to one another.

The stop element 45 can be positioned by means of adjustment means 48 in different stop positions, in each of which a desired one of the stop surfaces 47a, 47b, 47c can be used. The adjustment means 48 comprise a pivot bearing 49, via which the stop element 45 is mounted pivotably between the different stop positions on a fitting part in the form of a cover plate 50 of the furniture fitting 11. The cover plate 50 is fastened by means of suitable fastening means on the side of the support arm arrangement facing away from the side wall 14 of the furniture body 12.

That in the Figures 1 to 4 The stop element 45 shown is therefore located behind the cover plate 50 between the side wall and the rear of the cover plate. The pivot bearing 49 comprises an adjusting bolt 51 which passes through the cover plate 50 via a suitable passage opening. The stop element 45 is attached to the underside of the adjusting bolt 51, in particular connected to it in one piece.

When the adjusting bolt 51 is pivoted, the stop element 45 also pivots. The top of the adjusting bolt 51 protrudes beyond the front of the cover plate 50 and has an engaging section 52 on its top for engaging a suitable operating tool, for example a screwdriver. A swivel vane 53 is attached to the side of the adjusting bolt 51 and is part of holding means by means of which the stop element 45 and the adjusting bolt 51 connected to it are held in a fixed position in its set stop position.

The holding means are designed as latching means, a latching cam 54 being formed on the underside of the swivel wing 53, which can be latched into various latching openings 55 formed on the cover plate. This ensures that when the desired stop position is reached, the holding means also act at the same time in the form of the latching means, with which the stop position is fixed.

In the in Figure 1 The situation shown is the furniture flap 13 in the closed position. The stop element 45 is in the first stop position, whereby the first stop surface 47a acts as a usable stop surface. In the position shown, the first stop surface 47a forms the underside of the stop element 45, that is, it faces the force deflection lever 37.

When the furniture flap 13 is subsequently opened, it is swung open until the counter-stop 46, which is designed as a circumferential surface section of the force reversing lever 37, interacts with the first stop surface 47a, i.e. the counter-stop 46 strikes the first stop surface 47a. The counter-stop 46 is located on the circumferential surface section of the second lever arm 39b of the force reversing lever 37. The in Figure 2 The open position shown is reached after a relatively large opening angle.

With the stop element 45, a different open position can be specified in a very simple manner. For this purpose, an actuating tool, for example a screwdriver, is used to engage in the engagement section 52 of the adjusting bolt 51 and the adjusting bolt 51 is removed from the position shown in FIG Figure 1 The position shown is pivoted in the clockwise direction, whereby the coupled stop element 45 is also pivoted. As a result, the second stop surface 47b adjoining the first stop surface 47a now forms the underside of the stop element 45, i.e. it represents the usable stop surface in this case the middle locking opening) engages. The stop position of the stop element 45 is thereby fixed in position. The above-described opening process of the furniture flap 13 can then be initiated until the counter-stop 46 on the force deflection lever 37 strikes the now second stop surface 47b. In this case, the opening angle is smaller than in the previously described first stop position of the stop element.

To further reduce the opening angle of the furniture flap, i.e. to specify another of the open positions described, the adjusting bolt 51 is rotated further in a clockwise direction until the locking cam 54 engages in the associated locking opening 55, in this case the last locking opening 55. The stop element 45 is swiveled again, as a result of which the third stop surface 47c forms the underside of the stop element 45 in this case. During the opening process, the counter-stop located on the force deflection lever 37 can 46 hit this third stop surface 47c.
