[0001] "Device for a pivoting connection of a
[0002] Furniture body and a movable furniture part"
[0003] State of the art
[0004] Devices for pivotably connecting a furniture body and a movable furniture part are already known in the prior art. These devices, which are usually designed as hinges or fittings, can be connected directly to the furniture body and the movable furniture part. However, with these devices, it can happen that a furniture flap, for example, blocks the movement of a movable furniture part, such as a drawer.
[0005] This problem is solved by the device according to the invention.
[0006] Object and advantages of the invention
[0007] The invention is based on the object of providing an improved device for a pivotable connection between a furniture body and a movable furniture part. In particular, the device should advantageously fulfill mechanical and spatial requirements.
[0008] This problem is solved by the features of the independent claims.
[0009] The dependent claims specify expedient and advantageous developments of the invention.
[0010] The invention is based on a device for a pivotable connection of a furniture body and a movable furniture part, wherein the device comprises a fastening element which can be attached to the furniture body and a mounting element which can be attached to the movable furniture part, wherein the device comprises a housing element, wherein the housing element is received in an internal volume of the fastening element, wherein the housing element is connected to the mounting element by means of a first pivot axis, so that the mounting element and the housing element can be pivoted relative to one another about the first pivot axis.
[0011] For example, the device is designed as a furniture hinge or as a furniture fitting.
[0012] For example, the fastening element can be attached in the area of a narrow front side of a side wall or a top panel of a box-shaped furniture body.
[0013] For example, the mounting element can be attached to a narrow end face or wall of a movable furniture part, e.g., a furniture door or flap. The mounting element is designed, for example, in the form of a plate.
[0014] For example, the fastening element and the mounting element can be fixed or attached to the furniture body or the movable furniture part using fastening means such as screws.
[0015] For example, a width of the fastening element is not greater than a thickness of the panel-shaped side wall or the panel-shaped top panel of the furniture body. This allows the fastening element to be accommodated, for example, in a recess in the side wall of the furniture body, flush or nearly flush with a surface of the side wall or top panel of the furniture body.
[0016] For example, the width of the mounting element is not greater than the thickness of the panel-shaped door or flap. This allows the mounting element to be accommodated, for example, in a recess in the movable furniture part, flush or nearly flush with a surface of the movable furniture part.
[0017] The device makes it possible, in relation to the mounted state of the device, e.g. on the furniture or the furniture body and the movable furniture part, for no section of the device to protrude beyond a plane which is formed by an inner surface of the furniture body and / or the movable furniture part. The recessing of the device towards the inner surface sides, which can be achieved in all possible pivoting positions, and the accommodation of the device which thus does not protrude into a possible movement space of internal drawers of the furniture is advantageous, in particular functionally and technically but also visually.
[0018] It is also conceivable, for example, that when the device is mounted on the recesses of the furniture body and the movable furniture part, a flat section of the fastening element and / or mounting element protrudes by one to three millimeters above a plane of the respective inner surface. However, such a slight protrusion of the device, for example, into the interior of the furniture, does not pose any practical disadvantages.
[0019] The fastening element has, for example, a recess, wherein the housing element is accommodated, for example, in the interior volume of the recess. The housing element is accommodated, for example, in a movable, in particular linearly movable, manner in the interior volume of the recess. When the device is mounted on the piece of furniture, the recess in the fastening element is open, for example, towards the front side of a side wall of the furniture body or towards the furniture flap, wherein the housing element can be moved out of the open side of the recess.
[0020] The housing element is, for example, movable relative to the fastening element or the mounting element. It is also conceivable that the housing element is movable relative to the
[0021] fastening element and the mounting element is movable.
[0022] For example, the housing element and the mounting element are connected or connectable to one another detachably and / or without tools. For example, the mounting element has a rotary element, wherein the rotary element has, for example, two spaced-apart joint eyes. Furthermore, the housing element has, for example, a receiving element, which can be cylindrical, for example, and has a recess. The receiving element can, for example, be arranged between the joint eyes of the mounting element, wherein a pin element, for example, connects the receiving element of the housing element to the rotary element of the mounting element. For example, the pin element is inserted through the joint eyes of the rotary element and the recess of the receiving element.
[0023] The first pivot axis runs, for example, along the height or the longitudinal extent of the pin element. For example, the mounting element can be pivoted about the pin element or about the first pivot axis relative to the housing element. The pin element is, for example, a pin, a rod, or a bolt, wherein the pin element is preferably cylindrical.
[0024] The essence of the invention is that the device comprises a gear, the gear being designed such that the first pivot axis is displaceable as a result of a relative movement between the mounting element and the fastening element caused by the gear, the gear having a gear unit which interacts with a counterstructure on the housing element and with a counterstructure on the fastening element, the counterstructures having interaction regions, and the interaction regions of the counterstructures being axially offset from one another in the direction of the first pivot axis. The gear preferably comprises the gear unit and the two counterstructures.
[0025] For example, the counterstructures are designed as toothed racks. The counterstructures preferably have interaction areas, e.g. the teeth of the toothed racks, wherein the interaction areas are the areas of the counterstructures which are in temporary contact with the gear unit. For example, the gear unit has engagement areas which interact with the interaction areas of the counterstructures. For example, during the opening and closing movement of the movable furniture part or of the mounting element, the gear unit is moved along the counterstructure or the interaction area of the fastening element and the mounting element.
[0026] For example, the interaction area of the counterstructure on the fastening element is fixed to the fastening element. For example, the interaction area of the counterstructure of the fastening element protrudes into the interior volume of the recess in the fastening element.
[0027] For example, the counterstructure and thus also the interaction area on the housing element are movable, in particular linearly movable. The interaction area or the counterstructure of the housing element is, for example, movable relative to the counterstructure on the fastening element.
[0028] When the device is installed, for example on a piece of furniture, the fastening element remains in a fixed position during a pivoting movement of the movable furniture part relative to the stationary furniture body, while the mounting element is pivoted. For example, the counterstructure or the interaction area of the counterstructure on the housing element is moved, in particular moved linearly, during the opening movement of the movable furniture part or the mounting element in the opening direction. When the counterstructure or the interaction area on the housing element moves in the opening direction, the gear unit is rotated, for example. The gear unit is, for example, firmly connected to the housing element. This has the effect that, for example, the gear unit is moved along the counterstructure or the interaction area on the fastening element, in particular is moved linearly, as a result of which the housing element is moved, in particular moved linearly, in the opening direction.
[0029] For example, during a pivoting movement of the mounting element relative to the fastening element in a first pivoting direction, e.g. the opening direction, a distance of the first pivot axis to a reference point of the fastening element increases.
[0030] For example, the first pivot axis moves relative to the fastening element and the mounting element in a direction transverse to the first pivot axis, for example, in the direction of a longitudinal extension of the fastening element. For example, when the movable furniture part is opened relative to the furniture body, the first pivot axis moves horizontally forward or, relative to the fastening element, away from a rear side of the furniture body.
[0031] For example, an opening movement of the first pivot axis and thus of the movable furniture part connected to the first pivot axis occurs, composed or superimposed from two movement components. For example, in addition to the pivoting movement of the movable furniture part about the first pivot axis, a linear movement of the movable furniture part away from the furniture body or with an increase in distance from a front or front side of the fastening element and thus away from the furniture body occurs.
[0032] This allows, for example, the movable furniture part to perform an unhindered opening and pivoting movement on the furniture. Without extending the first pivot axis away from the fastening element, pivoting the movable furniture part from the closed position, which rests almost gaplessly against the furniture body, would not be possible, for example, without a device-side edge area of the movable furniture part striking the front of the furniture body.
[0033] For example, during a closing pivoting movement of the movable furniture part relative to the furniture body, the reverse process to the opening process takes place, or a reverse movement takes place by the same amounts as far as the pivoting and linear movement are concerned.
[0034] When the movable furniture part is closed relative to the furniture body, the distance between the first pivot axis and the fastening element decreases again. The first pivot axis moves back toward the fastening element, for example, or the housing element moves into the recess in the fastening element.
[0035] It is conceivable that the transmission unit comprises at least one gear element.
[0036] For example, the gear element has engagement areas. For example, the engagement areas are formed entirely on the gear element.
[0037] The gear element is mounted for rotation about a rotation axis, for example. The rotation axis runs parallel to the first pivot axis.
[0038] It is further conceivable for the gear element to have two engagement regions which are axially offset from the axis of rotation, one engagement region interacting with the counterstructure or the interaction region on the fastening element and the other engagement region interacting with the counterstructure or the interaction region on the mounting element. It is also conceivable for the gear unit to comprise a plurality of gear elements, a first gear element interacting with the counterstructure on the housing element and a second gear element interacting with the counterstructure on the fastening element. The two gear elements can then have a common axis of rotation. It is further conceivable for the rotational movement of the first gear element to be transmitted to the second gear element by a further element, for example a further gear element.For example, each gear element has an axis of rotation, wherein the axes of rotation are spaced from one another, for example in the opening and closing directions as well as along the first pivot axis.
[0039] It is also conceivable that the gear element is designed as a double gear element, wherein the double gear element is mounted so as to be rotatable about a single axis of rotation.
[0040] The double gear element has, for example, a recess into which a bearing element can be accommodated. The recess is formed, for example, centrally in the double gear element.
[0041] The bearing element is designed, for example, as a cylindrical bolt or pin. The bearing element can, for example, be fixed to the housing element, e.g., be firmly connected to the housing element. For example, the double gear element is rotatably mounted about the bearing element, with the axis of rotation running, for example, along the longitudinal extension of the bearing element. The axis of rotation runs, for example, parallel to the first pivot axis. For example, the longitudinal extension of the bearing element runs parallel to the longitudinal extension of the pin element.
[0042] For example, the double gear element has two gears, each with a gear contour, the gears and the gear contours having different diameters. For example, the gears have the engagement areas. For example, the gear contours of the gears form the engagement areas. Preferably, the gear contours or the engagement areas of the two gears are concentric to the common axis of rotation. For example, the gear contours or the engagement areas of the two gears are formed completely around the axis of rotation. For example, the two gears are rotated simultaneously about the axis of rotation.
[0043] For example, the double gear element comprises a larger and a smaller gear. Preferably, the larger gear meshes with the counterstructure or the interaction area of the counterstructure on the fastening element, and the smaller gear meshes with the counterstructure or the interaction area of the counterstructure on the housing element.
[0044] For example, both gears have the same number of teeth. It is also conceivable that the number of teeth on the gears is different. For example, the interaction areas of the counterstructures are adapted to the engagement areas of the gears. For example, the distances between the teeth of the racks or the interaction areas of the counterstructures are matched to the distances between the teeth of the gears. It is conceivable that the distances between the interaction areas or the teeth of the rack of the counterstructure on the housing element are smaller than the distances between the interaction areas or the teeth of the rack of the counterstructure on the fastening element.
[0045] It is also conceivable that the gear element comprises a roller pinion.
[0046] The roller pinion has, for example, a recess into which a bearing element can be received. The recess is, for example, formed centrally in the roller pinion. The bearing element is, for example, designed as a cylindrical bolt or pin. The bearing element can, for example, be attached to the housing element, e.g., be firmly connected to the housing element. For example, the roller pinion is rotatably mounted about the bearing element, with the axis of rotation running, for example, along the longitudinal extent of the bearing element. The axis of rotation runs, for example, parallel to the first pivot axis. For example, the longitudinal extent of the bearing element runs parallel to the longitudinal extent of the pin element.
[0047] For example, the roller pinion has roller bolts, with the roller bolts being mounted so they can rotate about a single axis of rotation.
[0048] For example, the roller pinion has two circular plates between which the roller bolts are arranged. For example, there are three circular plates in total, two of which are the same size and one of which is smaller. For example, the recess for the bearing element is located centrally in the circular plates. For example, roller bolts are arranged between the two equal-sized plates and roller bolts are arranged between a large and a small plate. The roller pinion has, for example, the engagement regions, with the roller bolts forming, for example, the engagement regions. Preferably, the roller bolts or the engagement regions of the roller pinions are designed concentrically to the common axis of rotation. For example, the roller bolts or the engagement regions of the roller pinions are designed to extend fully around the axis of rotation.
[0049] For example, the gear unit has two roller pinions of different sizes. Preferably, the larger roller pinion interacts with the counterstructure or the interaction area of the counterstructure on the fastening element, and the smaller roller pinion interacts with the counterstructure or the interaction area of the counterstructure on the housing element. For example, the roller pins of the roller pinions engage with the interaction areas of the counterstructures.
[0050] For example, both roller pinions have the same number of roller bolts. It is also conceivable that the number of roller bolts on the roller pinions is different. For example, the interaction areas of the counterstructures are adapted to the engagement areas of the roller pinions. For example, the distances between the teeth of the racks or the interaction areas of the counterstructure are matched to the distances between the roller bolts on the roller pinions. It is conceivable that the distances between the interaction areas or the teeth of the rack of the counterstructures on the housing element are smaller than the distances between the interaction areas or the teeth of the rack of the counterstructures on the fastening element.
[0051] It is conceivable that the mounting element is connected to the counter structure on the housing element by means of a swivel arm.
[0052] During the opening and closing movement of the device, the mounting element, the pivot arm, and the counterstructure on the housing element are preferably moved relative to the fastening element. Preferably, during the opening and closing movement of the device, the mounting element is pivoted about the first pivot axis and the pivot arm is pivoted about a second pivot axis.
[0053] For example, the mounting element has a connecting element which has a cylindrical recess. The pivot arm has, for example, a connecting unit. The connecting unit comprises, for example, two joint eyes, each with a cylindrical recess. For example, the connecting element is arranged between the joint eyes of the connecting unit. A connecting pin is preferably present in the cylindrical recess of the connecting element and in the connecting unit, which connects, for example, the mounting element to the pivot arm. The connecting pin is, for example, cylindrical. For example, the second pivot axis runs along the longitudinal extent of the connecting pin. For example, the second pivot axis runs parallel to the first pivot axis. For example, the longitudinal extent of the connecting pin runs parallel to the longitudinal extent of the pin element.For example, the second pivot axis runs parallel to the rotation axis.
[0054] For example, the mounting element can be pivoted relative to the pivot arm about the connecting pin. It is conceivable that the pin element is arranged at a distance from the connecting pin on the mounting element.
[0055] For example, the housing element is moved linearly perpendicular to the first pivot axis or along the longitudinal extension of the fastening element during the opening and closing movement of the mounting element or the movable furniture part. Furthermore, the first pivot axis is moved linearly along the longitudinal extension of the fastening element or perpendicular to the longitudinal extension of the pin element during the opening and closing movement of the movable furniture part.
[0056] The second pivot axis is pivoted, for example, with the mounting element during the opening and closing movement of the movable furniture part. In this case, the pivot arm, in particular one end of the pivot arm connected to the mounting element, is pivoted along with it.
[0057] For example, the swivel arm is connected to the counter structure on the housing element by means of a swivel element.
[0058] For example, the pivot element is designed as a bolt or pin. For example, the pivot element is cylindrical. For example, the pivot arm and the counterstructure have a receptacle, such as a cylindrical recess, for the pivot element. For example, the counterstructure has two joint eyes, between which the receptacle for the pivot arm is arranged.
[0059] For example, during the opening and closing movement of the movable furniture part, the pivot arm is pivoted about the second pivot axis, with the pivot element being moved linearly. The direction of movement of the pivot element is, for example, perpendicular to the first pivot axis or along the longitudinal extension of the fastening element. Due to the linear movement of the pivot element during the opening and closing movement of the movable furniture part, the counterstructure with the interaction area is also moved linearly.
[0060] It is also conceivable that the gear element is firmly connected to a housing of the housing element.
[0061] For example, the housing element comprises the housing, the pivot arm, the pivot element and the counter structure. Preferably, the housing of the housing element is received in an internal volume of the recess of the fastening element. The recess or the internal volume of the recess in the fastening element is, for example, adapted to the shape of the housing. Preferably, the housing is movable relative to the fastening element. For example, the housing is moved out and in within the recess of the fastening element during the opening and closing movement of the movable furniture part. For example, the pivot arm, the pivot element and the counter structure are movable relative to the housing.
[0062] The housing of the housing element has, for example, three sides, one of which is open, for example. For example, the three sides enclose an interior of the housing. For example, the counterstructure, the pivot element, and the pivot arm are arranged on the open side of the housing. The gear element is, for example, accommodated in the interior of the housing of the housing element.
[0063] The gear element can, for example, be connected directly to the housing of the housing element, e.g., be firmly connected. It is also conceivable for the gear element to be connected, in particular firmly connected, to the housing of the housing element via the bearing element. For example, the gear element or the bearing element is accommodated on two opposite sides of the housing.
[0064] It is also conceivable that the counter structure on the housing element is linearly movable perpendicular to the first pivot axis.
[0065] For example, the counterstructure with the interaction area on the housing element is moved linearly during the opening and closing movement of the device, in particular linearly along the longitudinal extent of the fastening element or perpendicular to the longitudinal extent of the pivoting element. For example, only a part of the counterstructure of the housing element has the interaction area.
[0066] For example, a guide slot is formed in the housing. The guide slot is, for example, recessed in the housing. For example, the guide slot is formed linearly in the housing, e.g., linearly along the longitudinal extent of the fastening element.
[0067] For example, the counter structure is moved along the guide slot in the housing, e.g. moved linearly. For example, the counter structure has a guide element, wherein the guide element is moved, e.g. along the guide slot, in particular is moved linearly. For example, the pivoting element is moved along the guide slot in the housing, e.g. moved linearly. It is also conceivable that the housing has a stop for the guide element and / or for the pivoting element. The stop in the housing blocks, for example, movement of the guide element and / or the pivoting element in the opening direction.
[0068] For example, the housing of the housing element has a recess, with a part of the gear unit projecting through the recess.
[0069] The housing of the housing element has, for example, on the side opposite the open side, a recess through which, for example, a part of the gear unit or gear element protrudes. For example, an engagement area of the gear element protrudes from the recess in the housing of the housing element, so that the gear unit or gear element engages with the counterstructure on the fastening element.
[0070] For example, if the gear element is designed as a double gear element, the engagement area of the larger gear protrudes from the recess. For example, if the gear element is designed as a roller pinion, the roller pins of the larger roller pinion protrude from the recess.
[0071] In a further essential aspect of the invention, a piece of furniture is provided with a furniture body and a movable furniture part, wherein a device for pivotably connecting the furniture body and the movable furniture part is provided according to one of the above embodiments.
[0072] For example, exactly two devices are provided per movable furniture part, which devices are attached to the furniture so as to be vertically offset from one another between the furniture body and the movable furniture part. For example, the furniture has one or more vertically offset interior drawers which are movably accommodated in an interior of the furniture. For example, the device makes it possible for no section of the device to protrude into the interior of the furniture when the movable furniture part is closed. For example, no section of the device protrudes beyond a plane of the inner surface side of the movable furniture part and a plane of the inner surface side of the furniture body when the movable furniture part is closed.
[0073] For example, there is a prepared recess in the furniture body into which the fastening element protrudes and is fastened.
[0074] For example, the walls of the furniture body are plate-shaped in an initial state. In one wall of the furniture body, a recess is present compared to the initial state; for example, the recess is milled out of a wooden material that is plate-shaped in the initial state. This allows for space-saving attachment of the device or the fastening element of the device to the furniture body. For example, a width dimension of the fastening element of the device is smaller than a width dimension of an end face of the furniture body wall, such as a width dimension of an end face of a side wall of the furniture body.
[0075] For example, the recess in a material of the, for example, plate-shaped side wall of the furniture body extends from a narrow front end, which is aligned vertically when the furniture is in use, over a depth of the furniture body from the end to the direction of a rear side of the furniture over 5 to 10 centimeters. For example, the recess is open to the front end of the furniture body. For example, the recess is open to an inside of the furniture body. For example, the recess is closed to an outside of the furniture body, for example covered on the outside by a flat and / or thin cover of the furniture body. For example, the recess is cuboid or cube-shaped. It is possible, for example, that the fastening element is received in the recess in the wall of the furniture body, with one wall of the fastening element ending with the wall of the side wall of the furniture body, e.g.flush or nearly flush. For example, the fastening element can be removably attached to the side wall of the furniture body using fasteners such as screws. The fastening element may, for example, have mounting holes.
[0076] For example, the fastening element has a recess with an open side, wherein the open side of the recess is formed on the front side of the side wall of the furniture body when the device is mounted on the furniture. For example, the housing element of the device can be moved in or out of the open side of the recess when the device is mounted on the furniture during the opening and closing movement of the movable furniture part, which changes, for example, the distance between the furniture body and the movable furniture part.
[0077] For example, there is a prepared recess in the movable furniture part into which the mounting element protrudes and is fastened.
[0078] For example, the movable furniture part is plate-shaped in its initial state. In contrast to the initial state, the movable furniture part has a recess made of a cuboid material, for example, milled out of a plate-shaped wooden material of the initial state. For example, the mounting element can be inserted into a recess in the movable furniture part. The recess is cuboid-shaped or cube-shaped, for example.
[0079] For example, the recess is open to an inner side and to a body-side end face of the movable furniture part. For example, the recess is closed to an outer side of the movable furniture part, for example, covered on the outside by a flat and / or thin cover of the movable furniture part. For example, a width dimension of the mounting element of the device is smaller than a width dimension of the movable furniture part, such as a panel-shaped door of the furniture.

[0097] The same reference numerals are sometimes used for corresponding elements of different embodiments.
[0098] Fig. 1 shows, for example, a piece of furniture 1 with a furniture body 2 and a movable furniture part 3, wherein, for example, two identical devices 4 are provided for pivotably connecting the furniture body 2 and the movable furniture part 3. For example, the piece of furniture 1 comprises a top panel 6, a bottom panel 7, a rear panel 8, outer side panels 9, inner side panels 5, movable furniture parts 3 and, for example, three interior drawers 10. For example, the inner side panels 5 are present within an interior of the piece of furniture 1. The interior drawers 10 can be extended in the direction L and are mounted on the piece of furniture 1 for linear movement, for example via rail guides (not visible), and are located in a fully retracted state on the piece of furniture 1 as shown in Fig. 1.
[0099] In Fig. 1, a movable furniture part 3 is in a partially open position on the furniture 1.
[0100] By means of the devices 4, which are designed as hinges, for example, the movable furniture part 3 can be pivoted about a first pivot axis S1 which is, for example, perpendicular or vertical in the used state of the furniture 1 or in the installed state of the devices 4. The first pivot axis S1 is provided, for example, by the devices 4. The movable furniture part 3 can be pivoted about the first pivot axis S1, for example, in an opening direction RI and in the opposite direction in a closing direction R2 (see Fig. 1). The device 4 comprises, for example, a fastening element 11, a mounting element 12 and a housing element 13. The fastening element 11 is accommodated, for example, in a recess 14 which is present in a side wall 5 of the furniture body 2. The recess 14 in the side wall 5 is, for example, open to the front side and to the interior of the furniture body 2.For example, the fastening element 11 is received in the recess 14 in such a way that the fastening element 11 is flush or almost flush with the surface side of the side wall 5 of the furniture body 2.
[0101] The mounting element 12 is accommodated, for example, in a recess 15 of the movable furniture part 3 that is open toward the pivot axis-side end face and open on the inside. For example, the mounting element 12 is received in the recess 15 in such a way that the mounting element 12 is flush or nearly flush with the surface side of the movable furniture part 3.
[0102] For example, in the closed state of the device 4, and thus with the movable furniture part 3 closed, the volume of the device 4 is completely or at least almost completely sunk in the region of the recess 14 in the furniture body 2 and in the region of the recess 15 in the movable furniture part 3.
[0103] For example, an inner surface side of the movable furniture part 3 closed on the furniture 1 can reach almost gap-free up to a narrow end face of the furniture body 2, such as a front vertical end face of a vertical furniture body wall.
[0104] This means that, for example, an inner drawer 10 of the piece of furniture 1, when the inner drawer 10 is fully pushed in or fully retracted, can occupy a space in the inner volume of the piece of furniture 1 that reaches as far as the inner surface side of the closed, movable piece of furniture 3, since no section or only an insignificant section, for example a small semicircular elevation or a flange thickness of a mounting flange of the device 4, protrudes into the interior.
[0105] For example, no essential section of the device 4 projects beyond the plane of the inner surface side of the side wall 5 of the furniture body 2 and the movable furniture part 3, even in all intermediate pivoting positions of the movable furniture part (see Fig. 13).
[0106] It is also possible with the device 4 to pivot the movable furniture part 3 over a comparatively large pivoting range, for example up to more than 90 angular degrees, e.g. up to 120 angular degrees relative to the closed position of the movable furniture part 3 on the furniture 1.
[0107] The fastening element 11 has, for example, a recess 16 which, when the device 4 is mounted on the piece of furniture 1, has an open side in the direction of the front side of the side wall 5 of the furniture body 2. The housing element 13, for example, is accommodated within an internal volume of the recess 16. For example, the housing element 13 is linearly displaceable relative to the fastening element 11, wherein the housing element 13 can be moved in and out of the open side of the recess 16. For example, the housing element 13 is moved along the longitudinal extent of the fastening element 11 within the internal volume of the recess 16.
[0108] The fastening element 11 has, for example, a counter-structure 18 which is present in the recess 16 (see Fig. 7, 10). The counter-structure 18 is designed, for example, as a toothed rack. The counter-structure 18 has, for example, an interaction region 39, such as the teeth in the toothed rack. The interaction region 39 of the counter-structure 18 points, for example, to the inner volume of the recess 16. For example, the teeth of the toothed rack are present in the inner volume of the recess. It is conceivable that, when the device 4 is mounted on the piece of furniture 1, the counter-structure 18 points to another adjacent inner side wall 5 of the piece of furniture 1 on the fastening element 11 (see Fig. 13).
[0109] The fastening element 11 has, for example, fastening holes 17 for fastening means, such as screws, wherein the fastening holes 17 are arranged in the mounted state of the device 4 on the furniture 1 on the front side of the side wall 5 (see Fig. 2) or on the surface side of the side wall 5 (see Fig. 3), which is aligned with the interior of the furniture body 1.
[0110] The mounting element 12 is designed, for example, in a plate-like manner. The mounting element 12 has, for example, mounting holes 17 for fastening means, such as screws. By means of the fastening means, the mounting element 12 is mounted, for example, to the movable furniture part 3, in particular to an inner surface side of the movable furniture part 3, which, when the furniture 1 is closed, is aligned with the interior of the furniture body 2.
[0111] The mounting element 12 has, for example, a rotating element 19 (see Fig. 4-10). The rotating element 19 comprises, for example, joint eyes, e.g., two separate joint eyes, which are provided on the mounting element 12, for example, at a distance from one another. A pin element 20, for example, can be received in recesses, in particular cylindrical recesses, of the rotating element 19 or the joint eyes. The pin element 20 is designed, for example, as a cylindrical rod or bolt. The first pivot axis S1, for example, runs along the height or longitudinal extent of the pin element 20. For example, the first pivot axis S1 runs centrally through the pin element 20.
[0112] The housing element 13 comprises, for example, a housing 21, a pivot arm 22, a pivot element 23, and a counterstructure 25. The housing 21 further comprises, for example, a receiving element 24. The receiving element 24 has, for example, a cylindrical shape with a recess. The receiving element 24 is arranged, for example, between the joint eyes of the rotary element 19, with the pin element 20 extending through the recess in the rotary element 19 and the recess of the receiving element 24.
[0113] The housing 21 is, for example, cuboid-shaped. It is also conceivable that two opposite sides of the housing 21 have a triangular shape with rounded corners, the other sides being straight. The recess 16 or the internal volume of the recess 16 in the fastening element 11 is, for example, adapted to the shape of the housing 21 so that the housing 21 can be received in the recess 16 of the fastening element 11. For example, the housing 21 is moved out and in within the recess 16 of the fastening element 11 during the opening and closing movement of the movable furniture part 3. For example, the pivot arm 22, the pivot element 23 and the counterstructure 25 are movable relative to the housing 21.
[0114] One side of the housing 21 is open, for example, with the pivot arm 22, the pivot element 23, and the counterstructure 25 being arranged on the open side of the housing 21. The open side faces, for example when the device 4 is arranged on the piece of furniture 1, the interior of the furniture body 2. The open side has, for example, a stop 26 for the pivot element 23. Furthermore, the housing 21 has, for example, a guide slot 27 for the pivot element 23.
[0115] The pivot element 23 is designed, for example, as a pin or bolt. The pivot element 23 connects, for example, the pivot arm 22 to the counter structure 25. In this case, the pivot arm 22 and the counter structure 25, for example, have a recess for the pivot element 23. For example, the recess is provided in the joint eyes of the counter structure 25 and the pivot arm 22, wherein, for example, the joint eye of the pivot arm 22 is arranged between two joint eyes of the counter structure 25. For example, the pivot element 23 is received in the recesses of the joint eyes of the counter structure 25 and the pivot arm 22. For example, the pivot arm 22 can be pivoted about the pivot element 23, wherein, for example, the pivot element 23 is moved linearly along the guide slot 27 during the opening and closing movement of the movable furniture part 3. For example, the movement of the pivot element 23 is limited by the stop 26.
[0116] The counterstructure 25 on the housing element 13 is, for example, plate-like. The counterstructure 25 is designed, for example, as a rack, wherein the counterstructure 25 has an interaction region 31. The interaction region 31 of the counterstructure, such as the teeth of the rack, is the region that comes into contact with a gear unit 32. The interaction region 31 or the teeth of the rack are, for example, aligned with the interior of the housing 21 of the housing element 13. The interaction region 31 is, for example, only partially formed on the counterstructure 25, wherein the interaction region 31 is, for example, axially offset to the first pivot axis S1 or along the longitudinal extent of the pivot element 23 relative to the interaction region 39 of the counterstructure 18 on the fastening element 11 (see Fig. 7, 10).
[0117] Another side of the housing 21 has, for example, an opening for the pivot arm 22, wherein the pivot arm 22 is permanently arranged in the opening. The pivot arm 22 is moved, for example, along the opening during the opening and closing movement of the movable furniture part 3 or the mounting element 12.
[0118] For example, the pivot arm 22 has a connecting unit 28, wherein the connecting unit 28 comprises, for example, two joint eyes. Furthermore, the mounting element 12 has, for example, a connecting element 29, wherein the connecting element 29 is arranged, for example, between the joint eyes of the connecting unit 28. The connecting element 29 and the connecting unit 28 are connected to one another, for example by means of a connecting pin 30. For example, the connecting pin 30 is received in the joint eyes. The connecting pin 30 has, for example, a cylindrical shape and is designed, for example, as a bolt or pin. For example, a second pivot axis S2 runs along the longitudinal extent of the connecting pin 30. The second pivot axis S2 runs, for example, parallel to the first pivot axis S1.
[0119] For example, the connecting element 29 is arranged at a distance from the rotating element 19 on the mounting element 12. For example, when the mounting element 12 is arranged on the movable furniture part 3, the rotating element 19 is arranged in the direction of the front side of the movable furniture part 3, and the connecting element 29 is arranged on the inner surface side of the movable furniture part, which is aligned with the interior of the furniture body 2.
[0120] For example, the device 4 comprises a gear 33, wherein the gear 33 comprises the counterstructures 18, 25 and the gear unit 32. The gear unit 32 comprises, for example, a gear element 34, wherein the gear element 34 is accommodated, for example, in the interior of the housing 21 of the housing element 13. For example, the gear element 34 is rotated about a rotation axis D, wherein the rotation axis D runs parallel to the first and second pivot axes S1, S2.
[0121] In a first variant, the gear element 34 is designed as a double gear element 35 (see Fig. 4-7) and in a second variant as a roller pinion 36, 42 (see Fig. 8-10).
[0122] The double gear element 35 has, for example, two gears 37, 38, wherein, for example, the diameters of the gears 37, 38 are different. For example, the gears 37, 38 have engagement regions that interact, e.g., come into contact with the interaction regions 31, 39 of the counterstructures 18, 25. For example, the gear contours of the gears 37, 38 form the engagement regions. Preferably, the gear contours or the engagement regions of the two gears 37, 38 are concentric with the rotational axis D. For example, the gear contours or the engagement regions of the two gears 37, 38 are formed completely circumferentially with the rotational axis D.
[0123] The larger gear 37 meshes, for example, with the interaction area 39 of the counter structure 18 of the fastening element 11. The smaller gear 38 meshes, for example, with the interaction area 31 of the counter structure 25 of the housing element 13. For example, a circular plate is arranged between the gears 37, 38.
[0124] The gears 37, 38 are axially spaced, for example, along the axis of rotation D, with a bearing element 40, for example, running through the center of the gears 37, 38. For example, the gears 37, 38 have a recess for the bearing element 40, with the recess being formed, for example, centrally in the gears 37, 38. The bearing element 40 is, for example, cylindrical in the form of a bolt, rod, or pin. For example, the axis of rotation D runs along the longitudinal extent of the bearing element 40. The bearing element 40 is, for example, connected, e.g., firmly connected, to the housing 21 of the housing element 13.
[0125] For example, the housing 21 has a recess 41 through which a part of the gear element 34 protrudes. For example, a part of the larger gear 37, e.g. the engagement area of the gear 37, protrudes through the recess 41 so that the larger gear 37 can come into contact with the interaction area 39 of the counter structure 18 of the fastening element 11. For example, the gear element 34 has two roller pinions 36, 42 of different sizes. For example, the roller pinions 36, 42 have two circular plates between which roller bolts 43 are arranged. For example, there are a total of three circular plates, with two plates being the same size and one plate being smaller. For example, roller bolts 43 are arranged between the two plates of the same size and roller bolts 43 are arranged between a large and the small plate (see Fig. 9).
[0126] For example, the roller pinions have engagement regions, wherein the engagement regions interact with the interaction regions 31, 39 of the counterstructures 18, 25. For example, the roller pins 43 of the roller pinions 36, 42 form the engagement regions. Preferably, the roller pins 43 or the engagement regions of the two roller pinions 36, 42 are formed concentrically to the rotational axis D. For example, the roller pins 43 or the engagement regions of the two roller pinions 36, 42 are formed completely circumferentially to the rotational axis D.
[0127] Preferably, the larger roller pinion 36 engages with the interaction area 39 of the counter structure 18 on the fastening element 11 and the smaller roller pinion 42 engages with the interaction area 31 of the counter structure 25 on the housing element 13.
[0128] For example, a hole for a bearing element 40 is provided centrally in the circular plates, wherein the bearing element 40 is designed, for example, as a cylindrical bolt or pin. For example, the roller pinions 36, 42 are rotatably mounted about the bearing element 40, wherein, for example, the axis of rotation D runs along the longitudinal extent of the bearing element 40. The bearing element 40 is connected, for example, to the housing 21 of the housing element 13, e.g., fixedly connected.
[0129] For example, the housing 21 has a recess 41 through which a portion of the gear element 34 protrudes. For example, a portion of the larger roller pinion 36 protrudes through the recess 41, so that the larger roller pinion 36 can engage the interaction area 39 of the counterstructure 18 of the fastening element 11.
[0130] In Figures 11 and 12, the device 4 is shown in different states of movement, wherein in Figure 11 the gear element 34 is designed as a roller pinion 36, 42 and in Figure 12 as a double gear element 35.
[0131] In Figure 11, the top image shows the device 4 or the movable furniture part 3 in the closed state.
[0132] For example, the position of the device 4 is referred to as closed if, in the assembled state, the movable furniture part 3 is positioned relative to the furniture body 2 in the same way as in an assembled state on a piece of furniture, in which the movable furniture part 3 is in a pivoted position that is closed on the furniture 1 or covers the front of the furniture. For example, in the assembled state of the device 4 on the furniture 1, the movable furniture part 3 is at a right angle relative to the furniture body 2, with a longitudinal axis of the fastening element 11 being at a right angle to the longitudinal axis of the mounting element 12.
[0133] In the closed state, the housing element 13 is, for example, almost completely received in the recess 16 of the fastening element 11, wherein, for example, the connecting unit 28 of the pivot arm 22 and the receiving element 24 of the housing 21 protrude from the recess 16 of the fastening element 11.
[0134] During the opening movement, for example, the mounting element 12 is moved about the first pivot axis in the opening direction RI. When the mounting element moves in the opening direction RI, for example, the second pivot axis is first moved approximately linearly. In the process, for example, the pivot arm 22 and the counter-structure 25 are also moved approximately linearly, whereby the interaction area 31 of the counter-structure 25 engages, for example, with the roller bolts 43 of the smaller roller pinion 42. In the process, both roller pinions 36, 42 are rotated, for example, about the bearing element 40, which is firmly connected to the housing 21, whereby, for example, the larger roller pinion 36 engages with the interaction area 39 of the counter-structure 18 (not shown) on the fastening element 11. Due to the rotational movement of the roller pinions 36, 42, for example, the larger roller pinion 36 is moved along the counter-structure 18 on the fastening element 11, whereby, for examplethe housing element 13 is moved out of the recess 16 of the fastening element 11. In this case, for example, the first pivot axis S1 or the pin element 20 is also moved linearly or along the longitudinal extension of the fastening element 11.
[0135] Upon further movement of the mounting element 12 in the opening direction RI, for example, the pivot arm 22 is pivoted about the second pivot axis S2 or the connecting pin 20 (see third illustration in Figure 11). The pivot element 23 and the counter structure 25 of the housing element 13 are, for example, still moved linearly. For example, the pivot element 23 is moved linearly along the guide slot 27 in the housing 21. For example, the smaller roller pinion 42 is moved along the interaction area 31 of the counter structure 25 on the housing element 13 and, for example, the larger roller pinion 36 is moved along the interaction area 39 of the counter structure 18 on the fastening element 11, wherein, for example, the housing element 13 is moved further out of the recess 16 in the fastening element 11. The first pivot axis S1 or the pin element 20 is, for example, still moved linearly or along the longitudinal extent of the fastening element 11.
[0136] In the fully open position of the movable furniture part 3 or the mounting element 12 (see bottom figure Fig. 11), an angle of, for example, 190°-225° is enclosed between the longitudinal axis of the mounting element 12 and the longitudinal axis of the fastening element 11. For example, the pivot arm 22 has a recess 44 in which the rotating element 19 of the mounting element 12 can be received. The pivot element 23 is moved, for example, along the guide slot 27 until the pivot element 23 reaches, for example, the stop 26. If the pivoting element 23 has reached the stop 26, for example, the last tooth of the counter structure 25 is in engagement with the smaller roller pinion 42. The larger roller pinion 36 is also in engagement, for example, with the last tooth of the counter structure 18 of the fastening element 11. A part of the housing element 13 is, for example, still received in the recess 16 of the fastening element 11.The distance between fastening element 11 and mounting element 12 or the first pivot axis S1 is, for example, maximum and corresponds to at least a thickness dimension of the panel of the movable furniture part 3, e.g., 10-25 mm. Preferably, the distance between fastening element 11 and mounting element 12 or the first pivot axis S1 is greater than a thickness dimension of the panel of the movable furniture part 3.
[0137] When the movable furniture part 3 or the mounting element 12 moves from the open position (lowest illustration Fig. 11) to the closed position (top illustration Fig. 11), for example, the roller pinions 36, 42 are moved along the counter structures 18, 25 in the closing direction R2, whereby, for example, the mounting element 12 is pivoted about the first pivot axis S1 and the pivot arm 22 is pivoted about the second pivot axis S2 in the closing direction R2. In this case, for example, the housing element 13 is moved into the recess 16 in the fastening element 11. The movement transmission of the movable furniture part 3 in the opening and closing directions is the same.
[0138] In Figure 12, the gear element 32 is designed as a double gear element 35, whereby in Figure 12 only the completely closed position (upper illustration) and the completely open position (lower illustration) are shown. The movement in the opening direction RI and closing direction R2 is analogous to that shown in Figure 11, the difference being that in Figure 12 a smaller gear 38 of the double gear element 35 meshes with the counterstructure 25 on the housing element 13 and the larger gear 37 of the double gear element 35 meshes with the counterstructure 18 on the fastening element 11, whereby the double gear element 35 is rotated about the bearing element 40.
[0139] In Figure 13, the device 4 is mounted on the furniture
[0140] 1, with the top figure showing the completely closed position. For example, the fastening element 11 is received in the recess 14 on an inner side wall 5, which is adjacent to another inner side wall 5. The mounting element 12 is received, for example, in the recess 15 on the movable furniture part 3, wherein another movable furniture part 3 is present. Both movable furniture parts 3 are, for example, in the closed state.
[0141] During the opening movement of the movable furniture part 3 or the mounting element 12 in the opening direction RI, for example, the mounting element 12 is pivoted about the first pivot axis S 1 , wherein the housing element 13 is moved linearly in the opening direction RI by the gear 33 from the recess 16 of the fastening element 11. In particular, the distance between the fastening element 11 or the furniture body
[0142] 2 and the mounting element 12 or the movable furniture part 3 is enlarged.
[0143] Upon further movement of the movable furniture part 3 or of the mounting element 12 in the opening direction RI, for example, the mounting element 12 is pivoted about the first pivot axis S 1 , wherein the pivot arm 22 is pivoted about the second pivot axis S 2 . In the process, for example, the counterstructure 25 is moved further out of the housing 21 of the housing element 13 . By means of the gear 33, for example, the housing element 13 is moved further out of the recess 16 in the fastening element 11, whereby the distance between the fastening element 11 or the furniture body 2 and the mounting element 12 or the movable furniture part 3 increases.
[0144] Due to the pivoting movement of the movable furniture part 3 and the linear movement of the movable furniture part 3 caused by the gear 33 of the device 4, the movable furniture part 3 is spaced further from the end face of the inner side wall 5 than the thickness of the panel of the other furniture part 3. As a result, for example, the opening movement of the movable furniture part 3 is not restricted by the other movable furniture part 3.
[0145] The device 4 is designed in such a way that, in the assembled state of the device 4, a movement of the movable furniture part 3, during an opening movement relative to the furniture body 2, takes place up to a maximum angular degree between 90 ° - 150 °, for example by 120 °.
