Description

The invention relates to a panel of a piece of furniture with a built-in or inserted hinge for guiding a movable part of a piece of furniture, in particular a door. The panel of a piece of furniture has two side surfaces, an end surface and an end surface recess for accommodating a hinge, while the hinge contains a main element, a linear guide and a rotary guide, while the linear guide is hinged at a distance from the main element. The invention also relates to a piece of furniture having at least one panel of a piece of furniture with such an integrated or inserted hinge.

Furniture, such as kitchen or living room furniture, such as floor or wall elements, often has a body of the piece of furniture open at the front, which can be closed by at least one door that is hinged and can be rotated about a vertical axis. The hinges are designed in such a way that the door performs a combined lift and turn movement, which allows the door to be opened even if the cabinet of a piece of furniture is directly next to another cabinet that also has a front door or drawer or other panel.

Usually the hinges are placed on the inner side wall of the body of the piece of furniture. The door, in turn, is either attached to the hinge using a mounting plate, or a so-called hinged cup is provided, which is completely or partially recessed into the door.

The combined lifting and pivoting movement of the door is achieved with the aforementioned mounted hinges by means of a linkage mechanism, often using a four-link linkage or, for large desired opening angles, also a seven-link linkage.

From DE 202015100934 U1 a door hinge is known which has a linear guide and a rotary guide connected to it. The linear guide is located in the housing, which can be inserted or built into the side panel of the housing of the piece of furniture. The linear guide displaces the guide arms, which are angled in the front area adjacent to the front of the side panel and protrude into the chassis. At the end of these angled guide arms, there are pivot pins to which pivot guide arms are hinged. When the hinge is closed, these levers sink into the cup of the hinge, which is recessed into the door of the piece of furniture.

Since the linear guide is integrated into the side panel, the hinge takes up less space inside the body of the piece of furniture. However, parts of the hinge, in this case the guide arms of the angled linear guide, still protrude into the housing when the hinge is closed. Accordingly, the side wall of the housing has holes for the guide levers inside. This prevents the free design of the interior of a piece of furniture.

From the publication DE 20023445 U1, a so-called milled hinge for a door is known, which has a linear guide and a rotary guide connected to it. Here, the linear guide is formed by the housing so that the linear guide has no other moving parts. The hinge can be inserted into a recess in the side wall of the cabinet of the piece of furniture, the recess facing the interior of the cabinet. The swivel guide has two crossed arms, one of which is rotatably and pivotally attached directly to the body, and the other is connected to the body through a linear guide. Also with this hinge, the pivot rail arms exit the side wall through a recessed opening on the inner side surface. This prevents the free design of the interior of a piece of furniture.

It is an object of the present invention to provide a piece of furniture panel for a body of a piece of furniture or a piece of furniture with an inserted or built-in hinge, which allows free interior design and prevents impacts on adjacent edges of the furniture. Yet another object is to provide a piece of furniture having at least one hinge and these advantages.

This task is solved with the help of a panel of a piece of furniture and a piece of furniture that have signs of the corresponding independent items. Preferred embodiments and further modifications are the subject of the respective dependent claims.

The panel of the piece of furniture according to the invention is characterized in that the linear guide and the articulation of the rotary guide with the linear guide are located between the first and the second plane, at least in the closed state of the hinge. The planes are defined by the two sides of the furniture panel as the planes in which the sides of the furniture panel are located (which are typically aligned parallel and spaced apart). In other words, the swivel projection of the pivot rail is at least in a closed state and preferably over the entire range of movement of the pivot on the front side surface.

In the panel of the piece of furniture according to the invention, the combined movement of lifting and turning of the attached movable part of the piece of furniture, in particular the door of the piece of furniture, is also achieved by the combination of a linear guide and a rotary guide. However, by moving the joint between the pivot rail and the linear rail in front of the end surface of the furniture panel, it is achieved that the inner surface of the furniture panel is not interrupted by the sideways protruding guide arms. Hinge points or hinge pins, in which the pivoting guide is connected to the linear guide, can be located inside the furniture panel itself or also in the extension of the furniture panel in front of the front surface of the furniture panel, for example, if a hinge cup is inserted, in which the hinge pins are then located. . Preferably, the two guides are (permanently) connected to each other in their movement sequence, for example, to ensure that the pivoting movement during the hinge opening process does not start until the linear guide has displaced the pivot points of the pivot guide from the piece of furniture panel to such an extent that the rotation can take place without collision. When the hinge is closed, this movement sequence is preferably carried out in reverse order.

In preferred embodiments of the piece of furniture panel, the linear guide has at least one movable slider and/or adjustment mechanism capable of generating a lifting movement via pivot arms. Therefore, the linear guide can be implemented in various ways, for example by means of at least one movable slider, which is preferably directed inside the base element and which can move in a direction that is preferably perpendicular to the front side of the furniture panel. In the second mentioned embodiment, the linear movement is realized as a lifting movement by means of pivoting arms, the arms being connected together, for example, in the form of a winch lift or a scissor lift. The winch hoist may, for example, have four arms connected by gear teeth, with the hinge pins extending through two of the arms. Preferably, the connected levers in pairs perform mirror-inverted synchronous pivoting movements.

In the context of the application, a linear guide is understood to mean a guide mechanism in which at least one element performs a directed linear movement. The fact that, in order to achieve linear movement of a given element, other elements perform rotational or other movements does not deprive such a guide of the character of a linear guide according to the application.

In a preferred embodiment of a linear guide with displaceable sliders, the linear guide comprises first and second sliders, the first slider being guided in the main hinge member and the second slider being directed relative to the first slider. One of the movable hinge pins may be located on each of the sliders, the hinge pins forming the pivot rail connections. In particular, if two sliders are connected to each other by a transmission mechanism with respect to their linear movement, the pivoting movement can be mechanically coupled to the linear movement in a simple and reliable manner.

The transmission mechanism may, for example, comprise two connected gears or friction wheels mounted on a common axis of rotation on one of the sliders, while the first of the gears or friction wheels is engaged in the rack or moves along the formed movement surface or is located on the main element, and the second of the gears or friction wheels is engaged in the rack or moves on a movement surface formed or located on the other slider. Such a transmission mechanism can be assembled in a compact manner and can therefore be easily incorporated into a narrow base element intended to be installed in a panel of a piece of furniture.

Preferably, the linear guide has a rocker guide for permanent connection (also called a positive connection) with a rotary guide, and the rocker guide contains a control track, which may be in the form of a cam guide or teeth.

In another preferred embodiment of the furniture panel, the pivoting guide has at least two spaced pivot pins which form a connection with the linear guide. Alternatively, a swivel gear with teeth on a swivel guide can be provided, whereby the connection to the linear guide can be realized via the swivel gear. The rotary guide can, for example, be made in the form of a four-link lever mechanism or contain such a mechanism. The four-link mechanism may, for example, have a control arm which is in the form of a double-sided lever and is engaged in a rocker guide formed on the sliding guide for constant guidance.

In one embodiment, the swivel rail is configured such that the U-bracket is guided through pivot pins around which the pivot cup is rotatably mounted. The rotary guide and the linear guide can be permanently connected with respect to their movements by means of gears engaged with each other, in particular bevel gears.

In a further preferred embodiment of the furniture panel, the hinge has a damping device for damping the closing and/or opening movement, the damping device being in the form of a linear damper or a rotary damper. The damping device provides comfortable and material-friendly handling of the piece of furniture by means of a movable part of the piece of furniture guided by the hinge of the panel of the piece of furniture. In order to achieve smooth and easy movement of the piece of furniture, the damping device is preferably connected, at least temporarily, to the element of the linear guide or the rotary guide.

Preferably, a (retractable) spring is also provided on the hinge, which acts on the linear guide and/or the attached rotary guide in such a way that it generates a closing torque against the damping device in an effective range between the closed position and the open position of the hinge. In this way, a secure closing of the hinge or the movable piece of furniture is achieved without the need to manually move the piece of furniture to the closing end position. The effective range is preferably between 0° and 45°.

The preferred damping device is a linear damper and has a cylinder, a piston rod and a system for changing the flow cross-section, whereby the piston rod applies a damping force, for example, in one direction of movement and applies almost zero damping force in the other direction of movement. In a linear damper, the damping effect is usually created in such a way that a viscous medium flows through the constriction as the piston rod moves in the cylinder. The system for changing the flow cross section makes it possible to make the damping effect particularly dependent on the direction of movement of the piston rod and/or its relative position in the cylinder in order to achieve optimum damping over the entire required range. The damping device may be actuated by a spring to such an extent that the piston rod automatically extends, the force of said spring being less than the force of the (retraction) spring.

In a further preferred embodiment of the panel of the piece of furniture, the hinge has an adjusting device for positioning the movable part of the piece of furniture in at least one spatial direction, the adjusting device having a worm, eccentric or screw element. In this way, the directional part of the piece of furniture can be easily aligned in its position with respect to the body in order to achieve, for example, a high quality appearance, for example with uniform gap dimensions despite manufacturing tolerances. The adjusting device is preferably suitable for adjustment in several spatial directions in order to be able to optimally adjust the dimensions of the gap in all directions.

In another preferred embodiment, the panel of the piece of furniture has a material thickness of less than 25 mm (millimeters), preferably less than 21 mm. In particular, the main hinge element has a thickness of less than 18 mm, preferably less than 16 mm. Thus, the hinge can be inserted into the panel of a piece of furniture with the usual thickness of the material and the usual proportions.

A piece of furniture according to the invention, having at least one movable piece of furniture, is characterized by the panel of the piece of furniture described above, comprising an inserted or built-in hinge for guiding the movable piece of furniture. This leads to the advantages mentioned in relation to the panel of the piece of furniture.

In a preferred further embodiment, the panel of the piece of furniture forms the vertical side wall and the movable guide portion of the furniture is the door. If a movable piece of furniture is located next to another movable piece of furniture or next to a wall, it can advantageously be provided that, in the open state, one end surface of the movable piece of furniture covers at least part of the end surface of a panel of the piece of furniture and/or the front surface of an adjacent additional movable piece. furniture.

The invention is explained in more detail below with the help of examples of embodiments given with reference to the drawings, in which:

In FIG. 1-5 show an example of a first embodiment of a piece of furniture panel with an inserted or built-in hinge according to the application. In FIG. 6a-12b show a second hinge that can be used in a panel of a piece of furniture in accordance with an application similar to FIG. 1-3.

Throughout the drawings, like reference numerals designate identical or similarly operable elements. For the sake of clarity, not every element in all drawings is identified by a position number.

In the description, terms such as "above", "below", "left", "right" refer solely to the exemplary display selected in the respective drawings. The terms "front" and "rear" generally refer to the orientation of the body of the piece of furniture, with front being the open side of the body of the piece of furniture that normally faces the user.

In FIG. 1-3 shows a sectional view of the corner portion of the body of a piece of furniture with an integrated hinge. The body of the piece of furniture has a side wall formed by the panel 1 of the piece of furniture. At the front (on the left in the drawings), the panel 1 of the piece of furniture, and therefore the side wall, has a recess 2 at the front into which a hinge is inserted or integrated. The hinge serves to guide the movable piece of furniture 3 which, in the closed position, closes the body of the piece of furniture which is open at the front. In the example shown, the movable piece 3 of the piece of furniture is the door of the piece of furniture. In the following, the term furniture door 3 will also be used synonymously.

In addition, the drawings show the front part 4 of the piece of furniture of the adjacent body of the piece of furniture, which is not shown in detail. The front part 4 of the piece of furniture can, for example, also be formed by another door of the piece of furniture, but also by a fixed front panel or a front panel mounted on a drawer.

In FIG. 1 shows the door 3 of the piece of furniture and hence the hinge in the closed position (hereinafter also referred to as the closed position). In FIG. 2 shows the partially open position of a piece of furniture or hinge door 3 with an opening angle of approximately 45 degrees. Finally, in FIG. 3 shows the fully open position in which the door 3 of the piece of furniture or the hinge in this example has an opening angle of approximately 110 degrees. Comparison of the three figures shows that the door 3 of the piece of furniture performs a combined lift and turn movement, with which the door 3 of the piece of furniture pivots in front of the front of the piece of furniture 4 in a partially open or fully open position.

The side wall is formed from a panel 1 of a piece of furniture in accordance with the application, in which the shown hinge is inserted or integrated. The piece of furniture panel 1 may have several hinges shown in line along the front side of the side wall, so that the fitted door 3 of the piece of furniture is directed to, for example, two or three of the hinges shown. In the panel 1 of the piece of furniture, a recess 2 is provided to accommodate the hinge from the front surface. This can be done subsequently with an appropriate milled recess, but it is also possible that the panel 1 of the piece of furniture is already made with an inserted hinge by forming it from a core and two cover panels, the core having a corresponding recess in the area shown, and the core together with the hinge or hinged to the cover panels, for example by gluing.

The hinge with the main element 10 is inserted into the recess 2 on the end surface, while the main element 10 is connected to the panel 1 of the piece of furniture, in this case to the side wall. This connection can be made, for example, by gluing and/or screwing, in particular through a recess 2 on the end face, into a core located behind the hinge. In addition, a quick fastening system can be provided for the connection, for example with a snap-on or fastening mechanism.

The main hinge element 10 is formed essentially in the form of a cube and is open at least on the front side, so that the hinge components can protrude through this opening and the opening of the recess 2 of the end surface of the side wall. In the base element 10 there is a linear guide 80 connected to a pivoting guide 90, which in turn is attached to the mounting element 20 on which the movable part 3 of the piece of furniture, in this case the door of the piece of furniture, is mounted.

In the present exemplary embodiment, the linear guide 80 has two movable sliders, in particular an outer slider 81 which is movably guided in the base member 10, and an inner slider 85 which is movable relative to the outer slider 81 and which is movably guided on that outer slider 81. The outer slider 81 and the inner slider 85 may, for example, each be made in the form of a U-shaped element, for example from stamped and embossed sheet metal. The two sliders 81, 85 are positioned on top of each other so that the outer slider 81 slides to guide along the surfaces of the main member 10 and the inner slider 85 slides to guide along the surfaces of the outer slider 81. The movement is in the horizontal direction, that is, in the plane of the sheets of the drawings shown. . Linear guide 80 moves forward or backward with respect to the body of the piece of furniture. In order to make it easier to see the contours of the inner slider 85, its boundary lines are not displayed as hidden lines.

In the embodiment shown, the movement of the two guides 81, 85 is permanently linked to the transmission unit. This is achieved with two gears, a first gear 88 and a second gear 89 which is non-rotatably coupled to it. Both gears are rotatably supported by a common slewing bearing 87, the spherical bearing 87 being formed on the inner slider 85. The first gear 88 has a larger diameter and meshes with the teeth (rack) formed on the respective inner side of the main member 10. The second gear 89 is engaged with the teeth formed in this case by a rack 84 formed on the outer slider 81. The connection of the two sliders 81, 85 is again shown in detail in FIG. 4 is an enlarged sectional view. It should be noted that the ratio of the diameters of the first and second gears 88, 89 in the drawings shown is schematic and purely exemplary and does not quantify the gear ratio.

The continuous connection of the sliders 81, 85 is clearly seen by comparing FIGS. 1-3 in various hinge opening states. When the linear guide moves forward to open the recess 2 of the end surface, the inner slider 85 covers a greater distance relative to the base member 10 than the inner slider 81.

In the corresponding front area of the outer or inner sliders 81, 85 are pivot pins 82, 86, to which the arms of the pivot rail 90 are connected. hinge axis 86 of the inner slider 85.

Both levers are pivotally connected at their free end with hinge points 24, 25 to the mounting element 20. In the embodiment shown, the mounting element 20 is a mounting plate, which is not visible here and has a protrusion protruding vertically from it, the hinge points 24 , 25 are located on this raised ledge. The two levers, the control lever 93 and the support lever 91, together with the respective hinge pins 82, 86 or hinge points 24, 25, form a four-link hinge, with which the door 3 of the piece of furniture can be pivoted.

In the closed position of the hinge shown in FIG. 1, the linear guide 80 is retracted as far as possible into the main element 10. The operating lever 93 and the support lever 91 are also completely retracted into the recess 2 of the end surface 1 of the piece of furniture, and also substantially completely into the main element 10. Both levers are aligned almost parallel to each other and extend substantially in the direction of the panel 1 of the piece of furniture. The protrusion of the mounting element 20 is also located inside the recess 2 of the end surface, so that the hinge points 24, 25 are also located in the region of the panel 1 of the piece of furniture. To provide more space for the protrusion of the mounting element 20 at this point, the main hinge element 10 is not directed towards the edge of the recess 2 of the end surface. However, in alternative embodiments, this is also possible. It is also possible that the side wall has a recess in the side wall so that the movable hinge parts can also use this space without the movable hinge parts protruding into the piece of furniture when closed.

When the door 3 of the piece of furniture is opened, for example to the position shown in FIG. 2, on the one hand, the linear guide 80 moves forward inside the furniture panel 1 and thus the side wall, and on the other hand, the levers 91, 93 rotate relative to the linear guide and also relative to the mounting element. The movement of the linear guide 80, in particular the outer slider 81 and the inner slider 85, is associated with the rotation of the levers 91, 93. This is achieved by the fact that one of the levers, in this case the control lever 93, is made in the form of a double-sided lever and projects beyond the shoulder lever behind the pivot pin 86. The control lever 93 is slightly curved. At the free end of the arm 92 of the control arm is a pin guiding in a slotted cam guide 83 which is formed on the outer slider 81.

The opening movement of the door 3 of the piece of furniture causes linear movement of the linear guide 80 due to the interaction of the control lever 93 or the arm 92 of the control arm in the rocker guide 83. The connection of the movement of the outer slider and the inner slider 81, 85, in turn, causes the rotational dynamics of the rotary guide 90 , so that, in general, the illustrated sequence of movements of the door 3 of the piece of furniture is forced. The final state of the opening movement is shown in FIG. 3. In this state, the linear guide 80 is extended to the maximum, whereby the hinge pins 82, 86 are pushed towards the front side of the furniture panel 1. However, they are still in the plane of the furniture panel 1, i.e. in the protrusion on the front of the furniture body, the hinge pins 82, 86 are located in the region of the front side of the furniture panel 1 and thus also of the side wall. When the door 3 of the piece of furniture is closed, the pivoting and sliding movement goes back respectively again until the state shown in FIG. one.

The combination of the linear and rotary motion of the rocker guide 83 is shown in FIG. 5, again enlarged. For clarity, in FIG. 5 does not show the elements of the self-closing and damping function described below.

To achieve end position damping, a damping device 70 is also provided. In the example shown, the damping device 70 is in the form of a linear damper with a cylinder 72 and a piston with a piston rod 73 moving in this cylinder. In the exemplary embodiment shown, the linear damper is engaged between the outer slider 81 and the inner slider 85 and thus dampens, at least in sections, the movement of the two sliders 81, 85 relative to each other. The damping device 70 can, for example, be designed in such a way that the damping of the movement of the two sliders 81, 85 towards each other occurs when the hinge moves towards the closed end position (FIG. 1). In this way, closing damping is achieved.

In addition, a self-closing function is provided, which in this case is implemented using a spring 75, made in this case in the form of a helical spring. The spring is located on the outer slider 81. One of the two spring arms, spring-loaded against each other, is supported by a pin, which is inserted into the outer guide 81. The second of these spring arms acts on the arm 93 of the control lever. In this way, self-closing in the closed position is achieved.

The drawings described below show further examples of a piece of furniture hinge suitable for being incorporated into a panel of a piece of furniture according to the application, for example the panel 1 of the piece of furniture shown in the first embodiment in FIG. 1-5

In FIG. 6a shows a perspective view of another example of a piece of furniture hinge in an assembled state in a central open position. The central open position means that the part of the piece of furniture guided by the hinge of the piece of furniture, in particular the door of the piece of furniture, is in the angular range between the closed state, in which the door rests with its free edge against the body of the piece of furniture, and the open position, in which the door has an opening angle , for example, 90° relative to the closed position.

The hinge of the piece of furniture has a main element 10, which is connected to the mounting element 20 by means of a lever mechanism. The door of the piece of furniture, for example, is mounted on a mounting element 20. The mounting element 20 is in the form of a hinged cup and is therefore also referred to as hinged cup 20 in the following. connected to the main element 10.

The main element 10 has an approximate shape of a cube or casing and has two parallel side panels 11 connected at their side edges by rounded transverse sides 13. In the hinge position of the piece of furniture, these transverse sides 13 are at the top and bottom, respectively. In the installation position from the front (on the right in FIG. 6a) the main element 10 is open, while at the rear (not visible in FIG. 6a) the rear side 14 preferably covers the main element 1. This rear side 14 is clearly visible, for example, in FIG. 7a and 7b, which are exploded perspective views of a piece of furniture hinge.

The main body 10 in the form of a casing has a cavity 15 in which a part of the hinge mechanism, described below, is located. The side panels 11 are preferably spaced so that the base element 10 can be inserted into a pocket-shaped recess in the front of the furniture panel which forms, for example, the side wall of the furniture body. The pocket, which is preferably milled from the end surface, has a shape that corresponds to the outer contours of the main element 1 thanks to the tool. Thus, this main element 10 can be inserted flush on all sides and thus well fixed in the side panel of the body of the piece of furniture and can be glued and/or fixed there, for example by means of screws that are screwed through the rear side 14 in material of the side panel of the body of the piece of furniture. The base element 10 can, for example, be made from suitably perforated sheet metal in rolled form. In a further embodiment, the main element 10 may have fastening bars that are suitable for fastening the main element 10 on the front side by means of screws or other fastening systems. For example, snap fastening such as fastening can also be implemented.

In both side panels 11 of the base element 10, holes 12 are provided in the front middle region to receive a support bolt (not shown here) and thus serve as anchor points. The support bolts pass through two additional arms 30, which are thus mounted in the base element 10 so that they can rotate about a horizontal axis (in the position of the hinge of the piece of furniture).

Other levers 30 are clearly visible in FIG. 7A and 7B. Each of them contains a lever arm 31 having a pivot hole 32 at one free end. At the opposite end, the gear wheel 33 is connected without the possibility of rotation with the arm 31 of the lever. In the embodiment shown, the arm 31 is formed with a slight offset and enlarged like a plate at its free end. The gear wheel 33 is mounted on this plate. It should be noted that in alternative embodiments, the teeth provided by the gear 33 may also be integrally formed with the arm 31 of the lever. Another hinge hole 34 passes in the center through the gear wheel 33.

With these additional pivot holes 34, the additional arms 30 are rotated on support bolts which are directed by the side panels 11. The distance between the holes 12 in the side panels 11 is chosen so that the two gear wheels 33 of the additional arms are engaged with each other, as a result of which the additional arms 30 perform a coordinated pivoting movement mirrored to the central axis of the main member 10. The pivoting movement of the additional arms 30 rotates 90° relative to the rotational movement of the door 3 of the piece of furniture, so that a scissor lift is created here. The pivotal movement of the additional arms 30 is responsible for the linear movement and thus the additional arms 30 form part of the linear guide 80 (see FIGS. 9a, 9b).

The free ends of the additional arms 30 are connected in other hinge holes 32 to the corresponding free ends of the arms 40. These arms 40 are supported at their respective additional ends in the hinge cup 20.

The location and support of the levers 40 in the hinge cup 20 are clearly visible in FIG. 1b and 1c, which show a perspective or plan view of the hinged cup 20 with inserted arms 40 separate from the main member 10 and additional arms 30. The hinged cup 20 has a base 21 and an edge 22 and is inserted in known manner into the cup opening of the door of the piece of furniture. for direction. It may be glued there, or fasteners may be provided along the edge 22 by which the hinged cup 20 is clamped, fixed, screwed and/or secured in the cup opening.

The structure of the lever 40 is again clearly visible in FIG. 7a and 7b. They are similar in design to the additional levers 30 and have a lever arm 41 with a pivot hole 42 at one end and teeth at the opposite end. The teeth in this case are formed by a mounted bevel gear 43. An additional hinge hole 44 passes centrally through the bevel gear 43.

In the hinge cup 20, two arms 40 are rotatably mounted by placing them together with other hinge holes on the leg 62 of the support bracket 60. The support bracket 60, in turn, is fixed in the hinge cup 20 by the base 61 so that it can rotate around of said base 61. To do this, a bracket attachment 23 is formed at a point on the edge 22 at which the support bracket 60 is inserted. Thus, the two legs 62 of the support bracket 60 form pivotal axes around which the levers 40 can be rotated. When the hinge of the piece of furniture is in the closed position, aligning the legs 62 and thus the support or pivot axes of the arms 40 parallel to the base 21 of the hinged cup. The swivel rail 90 is formed by the swivel bearing of the support bracket 60 in the hinge cups 20 (see FIGS. 9a, 9b).

In the exemplary embodiment shown, the hinged cup 20 is formed from a metal sheet through a stamping and bending process. The bracket mount 23 can be easily knocked out of the edge 22 and rotated inwards. Thus, the hinge cup 20 is made in one piece, including the bracket attachment 23. In alternative embodiments, the hinged cup 20 can also be made of plastic in an injection molding process, preferably also in one piece.

The articulating cup 20 has teeth 51 in the bracket attachment area 23 which is engaged with the bevel gears 43 of both second arms 40. In the embodiment shown, the gear train 51 is provided by a gear insert 50, which in turn is clearly visible in FIG. 7a and 7b. The teeth 51 have two sections of bevel gear facing each other, as well as an adjacent insert 52, which is inserted into a corresponding recess in the attachment area 23 of the bracket and fixes the toothed insert 50 to the hinge cup 20. In one embodiment of the hinge cup 20, in which it is made in the form of an injection molded part, the teeth 51 can also be formed directly on the hinge cup 20.

The two levers 40 are connected to each other by teeth 51 of the toothed insert 50 in such a way that, like the additional levers 30, they can only perform synchronous pivoting movements mirrored with respect to a vertical central plane. During this pivoting movement, the bevel gears 43 rotate on the teeth 51, causing the hinge cup 20 to rotate around the base 61 of the support bracket 60 relative to the plane in which the levers 40 are located.

In the assembled state of the hinge of the piece of furniture, the free ends of the additional levers 30 and the levers 40, which are located opposite the respective teeth, are connected in pairs. To do this, support bolts or rivets pass through hinge holes 32 and 42, respectively. Additional levers 30 and levers 40 together form a linear guide 80.

The movement sequence of the hinge of the piece of furniture is explained in more detail below with the aid of FIG. 8a, 8b, 9a, 9b, 10a and 10b.

In FIG. 8a and 8b show the assembled hinge of a piece of furniture in two axonometric views from different points of view. For a better overview, only one half of the main element 10 is shown.

In FIG. 8a and 8b, the furniture hinge is initially shown in the closed state, ie with the adjacent door of the piece of furniture. In this state, the hinged cup 20 rests with its edge 22 on the main element 10. Additional levers 30 are fully rotated into the cavity 15 of the main element.

In FIG. 9a also shows the closed state of the hinge of the piece of furniture, this drawing also showing half of the hinge cup 20.

Opening the door of the piece of furniture, i.e. turning the hinged cup 20, causes the teeth 51 of the hinged cup 20 to roll on the bevel gears 43, after which the levers 40 rotate towards each other from the position shown in FIG. 9a. When connecting the additional levers 30 to the levers 40, this rotation of the levers 40 towards each other is accompanied by a synchronous rotation of the additional levers 30 towards each other. This in turn kinematically causes an extension and hence a linear guide 80 of the linkage, with the support arm 60 and thus the hinge cup 20 moving linearly away from the main member 10.

In FIG. 9b shows the opening state of the hinge of the piece of furniture, for example, with an opening angle of 90° relative to the closed position. In this state, the additional interconnected arms 30 and the arm 40 form an extended arrangement in pairs, respectively, the hinged cup 20 and the door of the piece of furniture it holds move linearly from the side of the cabinet towards the room.

Therefore, the hinge of the piece of furniture shown performs a combined pivoting movement through the pivoting guide 90 of the hinge cup 20 with a linear movement through the linear guide 80. The linear movement moves the corresponding door of the piece of furniture such that its side edge moves in front of the front side of the adjacent door of the piece of furniture as viewed from the side. side of the user, so that the two doors do not collide when opened. As in the first example shown in FIG. 1-5, the pivot axes of the linear guide - the legs 62 of the bracket 60 - move so that they move through the entire range of movement between planes defined by the side surfaces of the panel of the piece of furniture. The pivot axis of the pivot rail 90, the base 61 of the arm 60, is located in front of the front surface of the furniture panel throughout the range of movement of the hinge, or in other words, the projection of the pivot axis is on the surface of the front surface in any hinge open state.

In FIG. 10a and 10b show the hinge of the piece of furniture in side view with transverse sides 13 of the main element 10. In FIG. 10a shows the open position of the hinge of the piece of furniture, and FIG. 10b shows a slightly closed position in which the hinged cup 20 is tilted and retracted minimally.

As a result of the kinematics of the arm, the linear and rotary movements of the cup 20 are related, but not linearly, to each other. Starting from the open position in which the linkage is stretched, the pivotal movement of the hinged cup 20 initially results in a slight linear movement. As the cup approaches the closed position, the linear movement becomes larger with respect to the change in angle. This results in an approximately sinusoidal function relationship. This is advantageous because, conversely, starting from the closed position, the initially smaller pivotal movement of the hinged cup 20 already results in a significant passage of the door of the piece of furniture, so that with continued pivotal movement of the hinged cup 20, the door of the piece of furniture has already moved far enough that it does not collide. with an adjacent piece of furniture door.

In the exemplary embodiment shown, both levers 40 and additional levers 30 are connected to each other by teeth in such a way that they perform the same rotational movements, mirrored in each case. The mirror-inverted pivoting movement performed by the levers 30, 40 relative to the linear guide 80 can also be realized in principle if only the two levers 40 are connected to each other by their teeth, for example bevel gears 43. However, the connection of both pairs of levers leads to more loaded guide.

In FIG. 11 and 12a, b show two additional embodiments of a piece of furniture hinge according to the side view application. The same reference numbers in these drawings designate the same or similar elements as in the previous drawings.

In their basic design, the hinges shown in FIG. 11 and 12a, b correspond to the example shown in FIG. 6a-10b. A non-limiting reference is made to the corresponding description.

The hinges shown in Fig. 11 and 12a, b each represent a further development of the hinge of the previous example. In particular, the hinge of the previous example is supplemented with a damping and/or self-closing function.

In the example of FIG. 11, a damping device 70 is provided for this purpose, which is in the form of a rotation damper. The damping device 70 has a ring gear 71 meshed with a gear 33 of one of the additional arms 30. When the pivot is rotated, the additional arm 30 rotates, causing the (rotational) damper to rotate and dampen the rotational movement. The damper can be designed in such a way that only certain parts of the rotational movement are damped, so that the hinge is damped when approaching the closed and/or fully open end position. In addition, the damper can be combined with a spring, such as a coil spring, so that the additional arm 30 is preloaded in the direction of rotation, such as in the direction of the closed end position of the hinge cup 20. In this way, a combined self-closing and damping function can be realized.

Since the movement of both additional arms 30 is coupled in the furniture hinge shown, it is generally sufficient to include such a damping device 70 acting on the gear wheel 33 of the additional arm 30. However, it would also be possible to include two such damping devices 70 to increase the damping forces.

In FIG. 12a and 12b show another embodiment with a damping device 70. In the example of FIG. 12a, analogous to the example of FIG. 11, only half of the main element 10 is shown, while in the embodiment of FIG. 12b, it has been completely removed to give an idea of the internal construction of the hinge.

In contrast to the embodiment of FIG. 11, in this case the damping device 70 is formed by a linear damper comprising a cylinder 72 with a piston and a piston rod 73. At the end of the piston rod is a pin 74, through which the piston rod 73 is connected to the linkage of the hinge. The cylinder 72 of the damping device 70 is rotatably mounted on the main element 10, for example, by means of a bolt or rivet passing through the side panels 11 of the main element 10.

In the example shown, the pin 74 is engaged in the connection of the lever arms 31 and 41 of the additional lever 30 or lever 40 and thus dampens the pivotal movement of these lever arms 31, 41. In alternative embodiments, other engagement points for pin 74 on lever arm 31 are possible. The damping device 70 dampens the rotational movement of the additional arm 30 as the hinge approaches the closed end position.

The exemplary embodiment of FIG. 12a and 12b also includes a self-return function which, unlike the example of FIG. 11 is not built into the damping device 70, but into the additional arms 30. In this example, both additional arms 30 are provided with a retractable spring. However, it is also possible to let the retracting spring act on only one of the additional arms 30. The springs themselves are not visible in FIG. 12a, 12b, they are located, for example, in the form of coil springs under the gears 33. The ends of the springs, which are supported on the main element 10, are shown as projections 35 in the drawings. A retaining clip 16, which is attached to one or both of the side panels 11, secures the tabs 35 in the position shown. It is also possible to make the retaining clip 16 spring-loaded so that it forms a retraction spring which acts on the two additional arms 30 by pressing the ends of the two additional arms 30 together.

In this example, two damping devices 70 may also be provided to achieve large damping forces, which then act independently on one of the additional arms 30.
