BACKGROUND OF THE INVENTION

The present invention relates to a furniture fitting for movably supporting a furniture part movably-mounted relative to a furniture carcass. The furniture fitting includes a first fitting portion configured to be fixed to a, preferably substantially horizontally aligned, furniture panel of the furniture carcass, and a second fitting portion configured to be fixed to the movably-mounted furniture part, in which the second fitting portion being pivotally connected to the first fitting portion. The first fitting portion includes a mounting portion having at least one fastening device for mounting the mounting portion to the furniture panel, and the first fitting portion includes at least one coupling portion hingedly connected to the second fitting portion. The coupling portion is configured to be releasably connected to the mounting portion, and the mounting portion of the first fitting portion includes a, preferably pocket-shaped, housing. The coupling portion, in a connected condition with the mounting portion, is received, for the most part, within the housing of the mounting portion.

Moreover, the invention concerns an item of furniture comprising a furniture carcass and a movable furniture part which is pivotally supported relative to the furniture carcass by at least one furniture fitting of the type to be described.

WO 2016/174071 A1 shows in FIG. 9 a furniture hinge for pivotally supporting a door, and the first fitting portion of the furniture hinge is countersunk is an elongated-shaped recess of a furniture panel of the furniture carcass. The second fitting portion of the furniture hinge is also received within an elongated-shaped recess of the movable furniture part.

EP 0 881 348 A1 discloses a hinge fitting having a door-sided fitting portion configured to be fixed to a door, a carcass-sided fitting portion configured to be fixed to the furniture carcass, and the carcass-sided fitting portion is hingedly connected to the door-sided fitting portion. The door-sided fitting portion includes a support body to be fixed to the furniture carcass, the support body being configured to be releasably connected by screws to a coupling portion of the hinge fitting.

WO 2016/090391 A1 discloses a furniture hinge having a carcass-sided fitting portion configured to be releasably latched with a (not shown) mounting plate by a spring-loaded locking lever, and the mounting plate is configured to be pre-mounted to the furniture carcass.

Upon mounting a movable furniture part to a furniture carcass, the furniture fitting is usually firstly pre-mounted to the movable furniture part. Subsequently, the movable furniture part, with the furniture fitting pre-mounted thereon, is approached to the furniture carcass, and it is thereby intended to introduce the first fitting portion into the provided recess of the furniture panel. Thereby, problems upon mounting may occur insofar because the movable furniture part, depending on its configuration, may have a considerable weight, and also because of the fact that the recess of the furniture panel must be precisely adapted to the form and size of the first fitting portion. Accordingly, the introduction of the first fitting portion into the recess of the furniture panel may, in fact, be connected with an expenditure of time and with a manually exhausting work process.

JP 2008-025270 A discloses a furniture hinge having a hinge housing which is to be fixed to a furniture part in a first mounting step. In a following mounting step, an adjustment block is inserted into a cavity of the pre-mounted hinge housing, and the adjustment block is connected to the hinge housing by screws.

SUMMARY OF THE INVENTION

It is an object of the present invention to propose a furniture fitting of the type mentioned in the introductory part, thereby avoiding the above-discussed drawbacks.

According to the invention, the coupling portion is configured to be releasably connected to the mounting portion by at least one locking device. The at least one locking device includes at least one movably-mounted locking element for releasably locking the coupling portion, and the at least one locking element is pressurized by at least one force storage member.

The feature of the locking device is certainly not an obvious measure in view of the JP 2008-025270 A reference, because it is quite unclear for the person skilled in the art, with a hinge housing countersunk into the furniture part, where to arrange the locking elements for releasably locking the coupling portion.

The carcass-sided first fitting portion of the furniture fitting has at least a two-part configuration and includes a mounting portion configured to be fixed, in a first mounting step, to or within a, preferably substantially horizontally aligned, furniture panel of the furniture carcass by at least one fastening device. Further provided is a coupling portion hingedly connected to the second fitting portion, and the coupling portion, in a second mounting step, is to be fixed—independently and separately from the mounting portion—to the movable furniture part. After the mounting portion and the coupling portion have been pre-mounted, these components can be releasably connected to one another by the locking device in a third mounting step, thus automatically locked to one another.

According to the invention, the mounting portion of the first fitting portion is configured to be inserted into a recess of the furniture panel, so that the mounting portion, in a mounted condition on the furniture panel, is, for the most part, preferably substantially entirely, received within the recess of the furniture panel. In this way, a compact and visually unobtrusive arrangement of the mounting portion on the furniture carcass can be provided.

The item of furniture comprises a furniture carcass having a, preferably substantially horizontally aligned, furniture panel (for example a bottom panel, a top panel, a shelf arranged between the bottom panel and the top panel, or a vertically extending sidewall), and the mounting portion is supported on the furniture panel. It is preferable that the mounting portion, in the mounted position, is for the most part received within a recess of the furniture panel.

The furniture panel of the furniture carcass usually has a predetermined material thickness (for example 16 mm or 19 mm). According to a preferred embodiment, the mounting portion of the first fitting portion is configured to be received within the predetermined material thickness of the furniture panel. The mounting portion can have a height extension and a length extension, and the length extension of the mounting portion is at least three times, preferably at least six times, as large than the height extension of the mounting portion.

For example, the furniture fitting can be configured as a furniture hinge. However, it is also possible that the furniture fitting is configured as a furniture drive for moving a furniture flap, the flap being pivotally supported about a horizontally extending axis in the mounted condition on the furniture carcass.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1a shows a perspective view of an item of furniture 1 with a furniture carcass 2 (only partially depicted). A movable furniture part 3, preferably in the form of a door or a furniture flap, is pivotally supported in the mounted position about an, preferably vertically extending, axis 14 relative to the furniture carcass 2 by a furniture fitting 4. The furniture carcass 2 includes a vertically extending sidewall 2a and a horizontally extending furniture panel 2b (preferably a top panel, a bottom panel or a shelf arranged between the top panel and the bottom panel), and the first fitting portion 5 of the furniture fitting 4 is supported on or within the furniture panel 2b. Of course, it is also possible for the furniture fitting 4 to be fixed to the vertically extending sidewall 2a, so that the movable furniture part 3, in the mounted condition, is pivotally supported relative to the furniture carcass 2 about a horizontally extending axis 14.

In the shown embodiment, it is provided that the first fitting portion 5 is substantially entirely received within a first recess 15a (FIG. 2a) of the furniture panel 2b, whereas the second fitting portion 6 of the furniture fitting 4 is substantially entirely received within a second recess 15b (FIG. 2b) of the movable furniture part 3.

FIG. 1b shows the furniture fitting 4 (without the mounting portion 8) in a perspective view. The first fitting portion 5 has at least a two-part configuration and includes a mounting portion 8 (FIG. 3a) configured to be pre-mounted to or within the furniture panel 2b, the mounting portion 8 having a, preferably pocked-shaped, housing 8a for at least partially receiving the coupling portion 9. The mounting portion 8 and the coupling portion 9 are configured to be releasably connected to one another. In a first mounting step, the mounting portion 8 is to be fixed to or within the furniture panel 2b. The coupling portion 9 is pivotally connected to the second fitting portion 6 by at least one hinged lever 7. The second fitting portion 6, in a second mounting step, is to be fixed to the movable furniture part 3 by a, preferably longitudinally extending, housing 6a. After the mounting portion 8 has been fixed to the furniture panel 2b and the second fitting portion 6 has been fixed to the movable furniture part 3, the mounting portion 8 and the coupling portion 9 can be connected to one another by joining them together. The mounting portion 8 and the coupling portion 9 are configured to be automatically locked to one another by at least one locking device 20 (FIG. 3a).

By at least one adjustment device 13a, 13b, 13c, in a connected condition between the mounting portion 8 and the coupling portion 9, a position of the coupling portion 9 relative to the mounting portion 8 can be adjusted, preferably in a three-dimensional manner. By a force of a spring device 10, the second fitting portion 6 is movable into a fully closed and/or fully open position relative to the first fitting portion 5. For example, this can be provided by a pressure roller 12 pressurized by the spring device 10. The pressure roller 12 is configured to run along a setting contour 24 (FIG. 3a) upon a movement of the hinged lever 7. By a damping device 11, preferably with a hydraulic piston-cylinder-unit, a movement of the second fitting portion 6 relative to the first fitting portion 5 can be decelerated. In this way, a movement of the second fitting portion 6 into the fully closed and/or fully open end-position can be dampened.

FIG. 2a-2c show the mounting procedure of the movable furniture part 3 on the furniture panel 2b of the furniture carcass 2 in schematic top views. A first recess 15a is formed in the furniture panel 2b for receiving the first fitting portion 5 of the furniture fitting 4, whereas a second recess 15b is arranged in the movable furniture part 3 for receiving the second fitting portion 6 of the furniture fitting 4. The first fitting portion 5 has at least a two-part configuration and includes a mounting portion 8 configured to be arranged in the first recess 15a, and a coupling portion 9 configured to be connected to the mounting portion 8. The first fitting portion 5 and the second fitting portion 6 are pivotally connected to one another by at least one hinged lever 7.

In a first mounting step (FIG. 2b), the mounting portion 8 is fixed within the first recess 15a of the furniture panel 2b, whereas the second fitting portion 6 is to be fixed to the movable furniture part 3. It is preferably provided that the longitudinal housing 6a of the second fitting portion 6 is configured to be substantially entirely countersunk in the second recess 15b of the movable furniture part 3. In a third mounting step (FIG. 2c), the mounting portion 8 and the coupling portion 9 are connected to one another, so that the movable furniture part 3 can be fixed to the furniture carcass 2.

FIG. 3a-3c show the mounting procedure of the coupling portion 9 on the mounting portion 8 in different mounting steps. The coupling portion 9 is connected to the second fitting portion 6 by at least one hinged lever 7. The hinged lever 7 is pivotally supported on the coupling portion 9 about a first hinge axis 17a, and is pivotally supported on the second fitting portion 6 about a second hinge axis 17b. A setting contour 24 is arranged on the hinged lever 7, and a pressure roller 12 pressurized by the spring device 10 is configured to run along the setting contour 24 upon a movement of the hinged lever 7 about the first hinge axis 17a. The hinged lever 7 is configured as a double-armed lever having a first lever end and a second lever end. The first lever end of the hinged lever 7 is hingedly connected to the second fitting portion 6 via the second hinge axis 17b. The damping device 11 is configured to be acted upon by the second lever end of the hinged lever 7. The second lever end of the hinged lever 7, for performing a damping hub, can act on the damping device 11 either directly or via at least one further component (for example via an intermediate lever). In a first mounting step, the mounting portion 8 is to be fixed by at least one fastening device 16 (which may be configured, for example, as a hole for receiving a screw) to or within the furniture panel 2b.

The mounting portion 8 can also include two or more fastening devices 16 configured as holes for receiving screws. It is also possible that the fastening device 16 includes a movably-mounted actuating element, and at least one locking portion is configured to be moved by an actuation of the actuating element. By the locking portion, the mounting portion 8 can be fixed to or within the furniture panel 2b in a force-locking manner.

In a further mounting step, the coupling portion 9 is inclinedly introduced into the pocket-shaped housing 8a of the mounting portion 8. Moreover, a centering device 18 for centering between the mounting portion 8 and the coupling portion 9 is provided. The centering device 18 includes at least one inclined surface 18a, 18b formed or arranged on the mounting portion 8 and/or on the coupling portion 9 for guiding the coupling portion 9.

For releasably locking between the coupling portion 9 and the mounting portion 8, at least one locking device 20 is provided. The locking device 20 includes at least one movably mounted locking element 25a for releasably locking the coupling portion 9. The locking element 25a is pressurized by a force storage member 21a, preferably configured as a compression spring.
