Description

The invention relates to a hinge for a furniture door, in which the first part of the hinge is made having a cassette-shaped body for integration into a furniture panel, and the second part of the hinge is in the shape of a hinge bowl for embedding into a furniture door, wherein the two parts of the hinge are rotatably connected to each other by lever mechanism, wherein at least one damper is located in the first part of the hinge for damping opening and closing. Furthermore, the invention relates to a furniture frame in which at least one such hinge is integrated.

Hinges are used to guide the door turning around a vertical axis in the furniture area. The advantageous combination of rotational and sliding movement of a connected furniture door can be achieved using a 7-link hinge, which allows installation with a small gap size in relation to adjacent and directly adjacent furniture frames that also have doors, leaves, etc. or drawers, without the collisions that occur when opening a furniture door. Hinges are often used in which the first part of the hinge is placed on the side wall of the furniture frame, and the second part of the hinge is made in the form of a hinge bowl, which is built into the inner surface of the furniture door. The disadvantage of these hinges is that they prevent free and arbitrary design of the inside of the furniture frame.

This disadvantage can be overcome by using hinges of the type mentioned above, in which the first part of the hinge is cassette-shaped and flat enough to be inserted into a furniture panel, for example the top or bottom panel of a furniture frame, into a suitable recess.

Such a door hinge is known, for example, from WO 2016/174071 A1. The hinge has a substantially rectangular accommodating cassette in a planar top view, in which is located a lever mechanism that extends from the mounting side of the furniture door upward to approach the edge of the bottom portion. The opening and closing damping mechanism and the spring mechanism that holds the hinge closed are located inside the first part of the hinge. The hinge has the disadvantage that the first hinge portion inserted into the top or bottom panel of the furniture frame occupies the front corner area of the furniture frame, so that the connecting members cannot be located between the top or bottom panel and the side portion of the furniture frame in the hinge area. It is only possible to glue the side panel to a narrow crossbar of the top or bottom panel, which still remains adjacent to the hinge. On the one hand, the stability of the furniture frame may be compromised, and on the other hand, the hinge can only be used in furniture frames in which the connection between the top or bottom panel and the side part is adapted accordingly, so that the recess into which the hinge part is inserted is not collides with connecting elements.

It is therefore an object of the present invention to provide a hinge capable of being incorporated into a horizontal panel of a furniture frame of the above type, which does not limit the use of traditional connecting elements between the panel and the side wall of the furniture frame.

This problem is solved with the help of a hinge or furniture frame having the features of the corresponding independent claims. Preferred embodiments and modifications are the subject of dependent claims.

A hinge according to the invention of the above type is characterized in that the body of the first part of the hinge is expanded in the front region in which the opening for the link mechanism is located relative to the rear region in which at least part of the link mechanism occupies space in the front expanded region in the closed position loops.

Thus, when viewed in the plane in which the lever mechanism is located, the body of the first part of the hinge is made, for example, stepped. Only the area in which the housing is open forward, and through which the lever of the lever mechanism passes between the first and second parts of the hinge, is made wide and extends to the very edge of the furniture panel. In the area located behind, the body is formed narrower, so that a wider part of the furniture panel remains, which on the one hand stabilizes the furniture panel in this area and, on the other hand, allows the placement of connecting elements, such as dowels, screws or eccentric connectors. Thus, the cabinet has a cabinet section that extends less deeply into the furniture panel than the rest of the main cabinet section. The body section itself is approximately 10 to 20 mm deep.

In traditional hinge use, the furniture panel is a horizontally aligned panel, such as the top, intermediate, or bottom panel of a furniture frame. The top, intermediate or bottom panel into which the hinge is inserted can be connected to the side wall of the furniture frame using connecting elements. Thus, a particular embodiment of the hinge body makes it possible to produce a furniture frame using traditional joining technology or to integrate the hinges according to the invention into a furniture frame thus produced. At least one connecting element may be located in the furniture panel for connection with an additional furniture frame component in the installation space behind the extended housing area and in front of the end of the rear housing area.

In one preferred hinge embodiment, the linkage mechanism includes an outer main arm and an inner main arm that are connected both rotatably on the body of the first hinge part and rotatably on the hinge bowl of the second hinge part. The main arms form the connecting mechanism of a hinge, specifically a 4-bar or 7-bar hinge.

The housing section that extends the housing laterally in the front region is preferably formed such that the inner main arm is located at least partially within the housing portion at least in the closed hinge end position. This is based on the conclusion that the housing does not necessarily have to penetrate equally deeply into the furniture panel everywhere, but does not have to be formed so deeply, in particular in the edge area in which the main arms of the linkage pass, with the result that the above-mentioned free space is provided for connecting elements. In one embodiment, the inner main arm is rotatably mounted within the housing and, in particular, also within said housing section.

In another preferred embodiment of the hinge, the front widened area faces towards the end of the furniture door on which the hinge bowl is located. A linkage mechanism also extends at this end, which may accordingly be at least partially receptive to this section of the housing. The hinge bowl may extend beyond the front widened area when closed towards the end of the furniture door on which the hinge bowl is located.

In another preferred embodiment of the hinge, a contour is provided at the front end of the housing to serve as an insertion stop for installing the housing into a furniture panel. Fasteners can be placed along the contour to connect the body to the furniture panel. In addition, the contour is preferably formed in a circumferential manner around the front end of the housing and overlaps a portion of the end surface of the furniture panel. In this way, the contour can be used to attach the hinge and hide the gaps between the hinge and the furniture panel for optical and hygienic reasons.

In another preferred embodiment of the hinge, a damper is provided as a functional part for damping closure and/or opening in the first and/or second part of the hinge. The damper may be a linear damper, which is designed as a tension or pressure damper, or a rotation damper. The damper preferably at least sometimes interacts directly or indirectly with the linkage mechanism.

In one preferred embodiment of the hinge, at least one of the two main arms is configured as a double-sided arm and is connected to a damper located within the housing. Thus, the movement of the second part of the hinge is transmitted through the levers to the damper to effect opening and/or closing damping. Since at least one of the main arms is configured as a double-sided arm, the movement of the arm can be transmitted inside the housing so that the damper can be located inside the housing. The movement of the main arms occurs in such a way that the extreme part of the path curve is present, for example, the protrusion of the outer main arm in a partially open hinge position. In this way, both closing and opening damping can be achieved with a single damper. However, it is also possible to implement damping only on closing or only on opening. The damper is preferably a linear damper which is rotatably mounted on one side to the housing.

In another preferred embodiment of the loop, the damper is connected to its other side directly along the length of the outer main arm.

Alternatively, an indirect connection to at least one of the two main levers is also possible. An indirect connection can be achieved by means of a control curve lever, the free end of which is connected to the damper and the other end of which is rotatably connected to the housing. The control curve lever has at least one control curve along which one end of the at least one main lever is guided. The control curve offers the possibility of influencing the angular dependence of the damping and thus, for example, adjusting the damping application points. A roller may be located at the end of the main arm to move along the control curve.

An indirect connection can also occur if the control arm is connected to an outer main arm and to an extension of the inner main arm and is guided at one end along a control curve. A roller may also be provided here to move along the control curve.

In another embodiment of the loop for indirect connection with the main levers, the damper is connected with the free side to two control levers, one of which is connected at the other end along the length of the outer main lever, and the other is connected along the length of the inner main lever.

In another preferred embodiment of the hinge, an elastic force accumulator, in particular a compression spring, is located in the housing to perform the function of holding it in the closed and/or open position. In this way, a furniture door can be reliably closed and/or reliably held in the open position, which avoids, for example, the risk of impact from accidentally partially opened doors. Instead of a compression spring, you can also use a leaf spring or a foot spring.

The force accumulator is preferably mounted with one end rotatably on the housing and connected at its other end directly along the length of the outer main arm. In one embodiment, the damper and force accumulator loops may be connected at a common connection point along an extension of the outer main arm.

In an alternative embodiment, it is provided that the power accumulator is connected by one side along the length of the outer main lever and connected by its other side along the length of the inner main lever. In both cases, the force accumulator is compressed more in the partially open loop position than in at least one of the extreme positions, causing the force accumulator to prestress the loop in the closed and/or open position. Accordingly, both the hold-close function for the closed position and the hold-open function for the open position of the loop can be realized using a force accumulator.

In another preferred embodiment of the hinge, the body of the first hinge part has a body width greater than the height of the body in the installed position. The hinge is therefore ideally suited for installation in a horizontally aligned furniture panel, in particular on the top, bottom or intermediate panel of a furniture frame. The height of the body of the first hinge part is preferably from 9 to 15 mm, while the width of the body of the first hinge part is from 30 to 100 mm.

The furniture frame according to the invention is characterized in that at least one such hinge is integrated into a panel of the furniture frame. The advantages mentioned regarding hinges are the result. The panel can be top, bottom or intermediate.

An example of a furniture frame 1 having a furniture door 9 is shown in an isometric view in each of FIGS. 1a, b.

As an example, the frame of a not very deep cabinet, such as a wall unit, is shown as a furniture frame 1. It will be appreciated that the illustrated furniture frame 1 is solely an example of the use of the hinge according to the invention, and the hinge can be used in other furniture frames or pieces of furniture having a furniture door .

The furniture frame 1 contains two panels 2, a top panel and a bottom panel. They are located between two side walls 3. The furniture frame 1 additionally has a rear wall 4.

A furniture door 9 attached on the left side is shown in the example of FIG. 1a and 1b, which is rotatably directed by the hinges 10. The rotation axis runs parallel to and in the region of the front narrow side of the left side wall 3 in the drawing.

Terms used in the description such as "top", "bottom", "left", "right" refer to the illustrative representation in the corresponding drawing. In contrast, the terms “front” and “rear” refer to the furniture frame 1, where the front side of the furniture frame is the user-facing side that is closed by the furniture door 9.

The furniture door 9 is shown in FIG. 1a in the closed position and in FIG. 1b in open position. The movement of the furniture door 9, controlled by the hinges 10, is a combined rotational and sliding movement, by which the furniture door can be opened with a small gap size of the furniture door in relation to adjacent pieces of furniture. Such movement of the furniture door 9 is achieved due to the design of the hinges 10 in the form of 4-link hinges.

As can be seen in FIG. 1b, the hinges 10 are integrated into the corresponding panel 2. In this way, the interior of the furniture frame 1 and in particular the side wall 3 remain free of hinge components, so that the interior can be designed freely. In particular, there are no restrictions on the positions in which intermediate panels or other classification or sorting systems can be located in the furniture frame 1.

In fig. 2 is a partial cross-sectional top view of the furniture frame 1 with the furniture door 9 open in the area of the hinge 10. The furniture frame 1 is shown in section in the area of the hinge 10 to give an idea of the location of the hinge 10 and its geometry within the panel 2.

The hinge 10 has a first hinge part 11, which is connected through a lever mechanism 13 to a second hinge part 12. Both parts 11, 12 of the hinge can be rotated relative to each other using a lever mechanism 13.

The first hinge part 11 is built essentially flush - possibly with the exception of a peripheral contour - into the panel 2. For this purpose, the panel 2 has a corresponding recess 5, which is, for example, milled into the panel 2. The second hinge part 12 is designed as a hinge bowl and is integrated flush into the furniture door 9, possibly with the exception of the mentioned contour, which can rest like a collar on the surface of the end surface of the panel 2.

The first hinge part 11 has a substantially flat cassette-shaped body, the thickness of which is designed such that the recess 5 can be inserted into the panel 2 without breaking off on the top, intermediate or bottom side during milling of the recess 5. With traditional thicknesses of the panels 2 in the range The body of the first hinge part 11 has a thickness of approximately 15-25 millimeters (mm), for example in the range of approximately 9-15 mm. As shown in FIG. 2, the body of the first hinge part 11 is wider in the front region, which extends to the narrow edge of the panel 2, than in the rear region, from which the first hinge part 11 projects deeper into the panel 2. Thus, the body of the first hinge part 11 is stepped in this horizontal the plane in which panel 2 is located and in which the lever mechanism 13 is also located.

Due to this staggering, a significantly wider edge 7 remains adjacent to the rear region of the first hinge portion 11 of the panel 2 than in the front region. The front region, in which the first loop part 11 is wider, extends to a depth in the range of approximately 10-20 mm. The remaining edge 7 located behind it stabilizes the panel 2 in this area and can advantageously be used to accommodate connecting elements between the panel 2 and the side wall 3. In the example shown, corresponding dowel holes 6 are inserted into the panel 2 and the side wall 3, in which hidden dowels 8 are inserted. It is obvious that in addition to or instead of said dowels, alternative connecting elements such as screws, strips or eccentric connectors can be used.

In the rear part of the recess 5 there are additional holes 6 for dowels. They house dowel elements, which are installed on the first part 11 of the hinge and are used to secure the first part 11 of the hinge in panel 2.

In fig. 3a is a top view of the furniture frame 1, in which the hidden lines are shown as dotted lines. In fig. 3a shows only the furniture frame 1 without the hinge 10 and without the furniture frame 9. From the hidden lines, on the one hand, it is possible to define a rear wall, which extends to the side walls 2 and can also be used as a connecting element between the side wall 3 and the panel 2. Alternatively or additionally, dowels can be inserted into the back of the furniture frame 1 between the panel 2 and the side wall 3.

On the other hand, the position of the recess 5 can be determined from the hidden lines. Dowels 8 are provided in the front region adjacent to the recess 5 on the remaining edge 7 between the panel 2 and the side wall 3, as shown in FIG. 2. In the same position, such dowels 8 are also placed in the dowel holes 6 for connecting the panel 2 with the opposite side wall 3.

In fig. 3a shows that due to the stepped formation of the body of the first hinge part 11 and the remaining edge 7, the same joining technology between the panel 2 can be used for both side walls 3. In other words, the typical joining technology that is used in furniture frames 1 between the panel 2 and side wall 3 can also be implemented using the built-in hinge 10 according to the invention.

In fig. 3b shows the edge region of the furniture frame 1 with the recess 5, shown once again enlarged and in more detail, in section, the section being made in a plane parallel to the surface of the panel 2.

A first exemplary embodiment of loop 10 is shown in more detail in FIG. 4a-6c.

The hinge 10 is shown in isometric view in the closed or open state, respectively, in FIG. 4a and 4b. In fig. 5a and 5b show top views of hinge 10, also in a closed or open state.

The first hinge part 11 has a cassette-shaped body 111 with two parallel plates, between which the components of the hinge 10 are located. The body can consist of multiple parts and be formed, for example, from two half-shells. The sides of the housing 111 are formed to be rounded into semi-cylinders to adapt the shape of the housing 111 to the shape of the milled holes in the panel 2 of the furniture frame 1. In this way, the housing 111 can be accurately inserted into the milled recess 5 (see FIG. 2). The section projecting on one side of the housing 111 in the front region is designated 112 in the drawings. The housing section 112 is located on the side of the housing 111 at which the linkage 13 exits the housing 111 in the open position (FIG. 4b).

The second hinge portion 12 has a hinge bowl 121, also synonymously referred to hereinafter as a bowl body 121, which in this example is L-shaped and includes a cross section 122. Protruding fastening tabs 123 having mounting holes are provided at both ends of the bowl body 121, which in this example is L-shaped. Instead of an L-shape, the hinge bowl may have a different shape.

The projections 123 rest on the surface of the furniture door 9 and can be screwed to the furniture door 9. Otherwise, the bowl body 121, including the cross section 122 thereof, is embedded in the material of the furniture door 9. The sides of the bowl body 121 have rounded half-cylinder shapes, as in housing 111 so that it can be accurately inserted into the corresponding milled hole in the furniture door 9.

Adjustment elements may be located in the housing 111 as well as in the bowl body 121 to be able to adjust the lateral, depth and/or vertical position of the furniture door 9. The position of the furniture door 9 relative to the furniture frame 1 can be adjusted using these adjustment elements, for example to be able to align the furniture door relative to adjacent furniture facades.

In the drawings of FIGS. 5a, 5b, the housing 111 is shown in sectional view in the region of the housing 112, as is the bowl housing 121, to show the location of the linkage 13 in this region. As a 4-link mechanism, the linkage mechanism has an outer main arm 131 and an inner main arm 132. They are rotatably connected to a holder 113, which is located in the area of the housing section 112. The holder 113 has two pivot points 114 on which the main arms 131, 132 are mounted.

The pivoting attachment of a component (eg, in this case, the main arm) that is secured relative to the housing 111 and thus fixed relative to the furniture frame 1 is referred to in the context of the application as a pivot point. Pivot supports that are not fixed relative to the housing 111, for example, because they are located on a lever that in turn can be moved, among other things, are called articulation points. Obviously, both the pivot point and the articulation point can be implemented in various ways, such as axles, rivets, bolts, etc.

The main arms 131, 132 are pivotally mounted at articulation points 124 on the side of the second hinge portion 12. As a result of execution in the form of a 4-link loop, the second part 12 of the loop performs a rotational and sliding movement relative to the first part 11 of the loop. For simplicity of illustration, the combined rotational and sliding motion is referred to as a pivoting motion in the context of this application. The shape of the main arms 131, 132 is such that in the open state of the hinge 10 they can be pressed against each other with the greatest possible accuracy of fit. In this way, the maximum possible opening angle is achieved, and at the same time the stop for the open position of the hinge 10 is determined.

In fig. 6a-6c, the hinge 10 is shown in cross-section, the cut being taken just below the top plate of the housing 111 so that the internal structure of the hinge 10 is visible. The drawings show the opening sequence of the hinge 10, which is illustrated in FIG. 6a in the closed position, in FIG. 6b in a partially open position and in FIG. 6s in fully open position.

In the hinge 10, the outer main lever 131 is designed as a double-sided lever and accordingly has a protrusion 133 beyond the pivot point 114. This protrusion 133 of the outer main arm 131 projects into the interior of the housing 111.

Housing 111 houses a damper 14, in this case a linear damper, having a cylinder 141 in which a piston (not visible here) is damped, and which is connected to a piston rod 143. The damper 14 is connected at one end, in this case the end of the cylinder 141, at the pivot point 115 with the housing 111. In addition to rotation around the pivot point 115, rotation around an axis perpendicular to it is provided by the rotary connection 142. This rotation is relevant, for example, if the hinge 10 offers the possibility of adjusting the vertical position of the furniture door 9, which is carried out by adjusting the inclination linkage 13 and, in particular, the outer main link 131. In this case, a rotary connection 144 is also provided at the end of the piston rod. The piston rod 143 is connected through this rotary connection 144 to a point of articulation 145 at the end of the extension 133 of the outer main arm 131.

In addition, a compression spring 15, which is rotatably mounted at a pivot point 116 with one end fixed relative to the housing 111, is located in the housing 111 as an energy or force accumulator. At the other end, the compression spring 15 is also connected by an articulation point 151 to an extension 133 of the outer main arm 131. In the illustrated exemplary embodiment, the articulation point 145 of the damper 14 and the articulation point 151 of the compression spring 15 coincide. Thus, a central articulation point is formed between the end of the extension 133, the damper 14 and the compression spring 15.

As shown by comparing the positions of the outer main arm 131 or the extension 133 in FIG. 6a-c, the center point of the articulation 145, 151 performs a rotational movement such that the damper 14 extends further in an intermediate position (see FIG. 6b) with respect to both end positions (fully closed or fully open), while the compression spring 15 compresses more strongly in the intermediate position than in the final positions. In this way, approach damping to both the closed and open end positions is achieved. In addition, due to the compression spring 15, the loop 10 is pre-tensioned in both the closed and open positions, thereby achieving the function of holding in the closed position or in the open position.

At the rear of the housing 11, two mounting options 118 are provided in the form of screw holes, with which the housing 111 can be secured in the recess of the panel 2. You can screw screws directly through this mounting option 118 into the panel 2, or you can also secure the dowel sections to the housing 111 with using fastening option 118, wherein the dowels fit into the corresponding dowel holes 6, as shown in FIG. 2.

A second example loop 10 is shown in FIG. 7a-7c are the same as in FIG. 6a-6c. Identical reference numerals denote identical or identically operating elements as in the first exemplary embodiment in these as well as in the following drawings. Reference is made to the first exemplary embodiment with respect to the basic structure of the hinge 10. In particular, the shape of the housing 111 in which the housing 111 is expanded only in the front region is also implemented by the housing section 112 in this and the following exemplary embodiments.

In this exemplary embodiment, the housing 111 also houses a damper 14 and a compression spring 15 that interact with the extension 133 of the outer arm 131. However, unlike the first exemplary embodiment, the compression spring 15 and the damper 14 are not coupled to the extension 133 in a central common point of articulation. Instead, the compression spring 15 is coupled at articulation point 151 directly to a length 133, while the damper 14 interacts via a control curve arm 146 to a length 133. To achieve this, an arcuate control curve arm 146 is rotatably mounted to a housing 111 at one end at a pivot point 117 , and the opposite free end of the control curve arm 146 is connected at a point of articulation 145 to the piston rod 143 of the damper 14. The rotary roller 134, which rolls along the control curve 1461 of the control curve arm 146, is secured to the free end of the protrusion 133 of the outer main arm 131.

As can be seen by comparing the opening sequence of hinge 10 in FIG. 7a-c, the compression spring 15 is also compressed more in the intermediate position (see FIG. 7b) than in the end positions in this embodiment, while the damper 14 extends further in the intermediate position than in the end positions.

As in the first exemplary embodiment, damping is achieved when approaching both end positions, and a hold-close function in the closed state and a hold-open function in the open state are achieved. In this exemplary embodiment, the angular dependence of the damping effect can be advantageously influenced by a design variation of the control curve shape 1461.

Two additional embodiments of the hinge 10 according to the invention are shown in FIG. 8a-c and 9a-c are the same as in FIG. 6a-c and 7a-c. In contrast to the drawings described above, FIGS. 8a-c and 9a-c are somewhat more schematic and illustrate the hinge 10 in a situation of installation in a furniture frame that is located next to another furniture frame. The side wall 3 and the furniture door 9 are shown on an additional furniture frame.

The design of the loops 10 in FIG. 8a-c and 9a-c generally correspond to those of the exemplary embodiments described above referred to herein. Unlike the exemplary embodiments described above, the outer main arm 131 and the inner main arm 132 are formed longer than in the previous exemplary embodiments, such that the pivot points 114 are no longer in the area of the body section 112, but are located further in the main body section 111. However, at least the inner main arm 132 extends through the housing section 112.

In the example of FIG. 8a-c, both main arms 131, 132 extend into the housing 111. Thus, in addition to the extension 133 of the outer main arm 131, the extension 135 of the inner main arm 132 also projects into the housing 111.

The housing 111 also houses a damper 14 and a compression spring 15. The compression spring 15 is not secured on both sides to the housing 111 in this exemplary embodiment and thus does not have a fixed pivot point, but rather is coupled at both ends at articulation points 151 with a length 133 of the outer main arm 131 on one side and a length 135 the inner main arm 132 on the other side of the compression spring 15.

Damper 14 is, as before, connected to one side, for example again on the cylinder side, at pivot point 115 to housing 111. The opposite side of damper 14, in this case the piston rod, is connected at articulation point 145 to lengths 133, 135, in in particular, through two control levers 136 placed between them. Both control levers 136 are rotatably connected to the damper 14 at said pivot point 145 . One of the control levers 136 is connected at an articulation point 137 to the end of the extension 133 of the outer main lever 131, and the other at the articulation point 137 with the end of the extension 135 of the inner main lever 132. In FIG. 8a-c show a dotted motion curve that the articulation point 145 performs during the opening or closing motion. As in the exemplary embodiments described above, compared to the end positions, the compression spring 15 is compressed more in the intermediate loop position, while the shock absorber 14 is deflected further. Damping occurs at each of the end positions due to the damper 14, and the holding function in the closed or open position occurs due to the compression spring 15.

In the example of FIG. 9a-c, the damper 14 and the compression spring 15 are connected to the two main levers 131, 132 via an additional control lever 136. It is connected at one end at the articulation point 137 on the outer main arm 131. The extension of the main arm 131 (see extension 133 in the illustrative embodiments illustrated above) is not required in this exemplary embodiment. In contrast, the inner main arm is formed as in the example in FIG. 8a-c as a double-sided lever and accordingly has a length 135. The control lever 136 is connected to this length 135, which is clearly visible in the enlarged view of the corresponding part in FIG. 9a. This connection has an articulation point 137 along a length 135, which is guided in the control lever 136 into an elongated hole 137', which also represents a control curve in this sense.

The control lever 136 ends, on the one hand, with an actuating protrusion 138, and on the other hand, with a roller 139. The actuating protrusion 138 interacts with a compression spring 15, which is fixed on one side in a spring mount 119 with the possibility of adjustment in the longitudinal direction on the housing 111 in this exemplary embodiment. The opposite free end of the compression spring 15 is also provided with a roller 152, which is pressed against the actuating projection 138 of the control lever 136. During opening or closing of the hinge 10, the actuator 138 moves towards the compression spring 15, causing it to be compressed. The actuator 138 also moves in a direction perpendicular to the axis of the compression spring 15 at the same time, which is possible due to the roller 152. The actuator 138 may further have a curved contour with which the deflection of the compression spring 15 can be further varied depending on the position of the loop.

Comparison of Figs. 9a-c shows that the compression spring 15 is also compressed more strongly in the intermediate state (see FIG. 9b) than in at least one end position in this exemplary embodiment, whereby the function of holding in the closed position and/or holding in the open position is accordingly achieved again.

The damper 14 is rotatably connected to the body 111 at one end at a pivot point 115 in this exemplary embodiment, and the other end, in this case a piston rod, is connected to a control curve lever 146, which is reversible in this exemplary embodiment. This lever is mounted on the housing 111 with the possibility of rotation relative to it at the turning point 117. The control curve 1461 is formed on the control curve lever 146 in the region in which the roller 139 of the control lever 136 is pressed against it.

During the opening or closing procedure of the hinge 10 (see the sequence in Fig. 9a-c), the roller 139 moves along the control curve 1461 of the control curve lever 146 at the end of the control lever 136, as a result of which the movement of the main lever 131, 132 is transmitted to the damper 14. Further the deflection of the damper 14 compared to the end positions is achieved in the intermediate position shown in FIG. 9b. Accordingly, as damper 14 is retracted, damping is achieved as each of the two end positions is approached.

Another example of a loop 10 according to the invention is again shown in FIG. 10a-d similar to FIG. 6a-c and 7a-c. The design of the hinge 10 here also generally corresponds to the designs of the exemplary embodiments described above, which are referred to herein. In particular, differences from the exemplary embodiments described above are explained below.

As in the examples in FIGS. 6a-c and 7a-c, the pivot points 114 of both main arms 131, 132 are located not in the main housing section 111, but inside or in front of the housing section 112. In addition, the outer main arm 131 also extends into the main body section 111 as a double-sided arm.

An extension 133 of the outer main arm 131 is coupled in this exemplary embodiment at an articulation point 151 to a compression spring 15 . The compression spring 15 is pivotally connected over an extension 133 at a given connection point 151 to an end freely movable laterally in the plane of the lever. The other side of the compression spring 15 is pivotally mounted in the housing 111 at a pivot point 116.

Both the outer main arm 131 and the inner main arm 132 act on the damper 14. To do this, the control curve arm 146 is connected to the inner main arm 132 at an articulation point 147, which acts through the roller arm 148 on the damper 14. In addition, on the angular position The control curve lever 146 is influenced by the position of the extension 133 of the outer main lever 131. The interaction of said levers is explained in more detail below.

The damper 14 is fixed to one side, such as the side of its cylinder 141 in this case, with the possibility of rotation at a pivot point 115 in the housing 111. The opposite side of the damper 14, in this case the end of the piston rod 143, is connected at a connection point 145 to the roller lever 148. This roller arm 148 is pivotally mounted at a pivot point 149 on the housing 111.

The roller lever 148 has the shape of a plate on which two rollers 1481, 1482 are rotatably mounted. Instead of the rollers 1481, 1482, bolts with external roundings can also be used. The rollers 1481, 1482 are pressed against the control curves 1461, 1462 of the control curve lever 146.

The control curve lever 146 is split at its free end in a fork or claw shape, resulting in an inner concave control curve 1461 and an outer convex control curve 1462. Depending on the open position of the hinge 10, roller 1481 is in contact with control curve 1461, and/or roller 1482 is in contact with control curve 1462.

In addition, an additional control curve 1463 is formed on the lower part of the control curve lever 146 in front of the fork, at the bend of which there is contact with a roller 152, which is rotatably mounted at the articulation point 151 of the compression spring 15 along the length 133 of the outer main lever 131. Angular position of the lever 146 the control curve is determined by the outer main lever 131 due to the rolling of the roller 152 along the additional control curve 1463.

The starting points of the damper 14 and the damping force curve can be set intentionally and differently for closing damping and opening damping by positioning the rollers 1481, 1482 on the roller arm 148 and generating the control curve 1461-1463.

In fig. 10a shows loop 10 in a closed state. The compression spring 15 is at its maximum weakened level and the damper 14 is almost completely retracted, resulting in the transfer of force between the control curve lever 146 and the damper 14 through the contact of the roller 1482 with the outer control curve 1462.

In fig. 10b and 10c show the hinge in two different partially open positions.

In the position shown in FIG. 10b, there is currently a transition between self-closing or closing damping and self-opening or opening damping. In this state, the compression spring 15 is stretched to its maximum and the damper 14 is fully extended. In this position, both rollers 1481, 1482 are in contact with the corresponding control curve 1461, 1462.

In the position shown in FIG. 10c, there is a transition from exclusive contact of the roller 1481 with the internal control curve 1461 to opening damping. In the maximum open position from Fig. 10d, the damper 14 is then almost completely retracted and the compression spring is slightly relaxed. The difference in spring tension in the closed position from Fig. 10a and the open position of FIG. 10b causes self-opening with less force than in the case of self-closing.

Six different embodiments of hinges 10 are shown in FIG. 11a-16b, which differ in the shape of the main arms 131, 132. The figures with the suffix "a" illustrate the hinge 10 in the closed position, and the figures with the suffix "b" illustrate the same hinge in each case in the open position.

Same as in FIG. 8a-c and 9a-c, loops 10 from FIG. 11a-16b are shown in the installed position of a furniture frame 1 with a door 9, which is located next to another furniture frame, the side wall 3 and door 9 of which are shown.

In fig. 11a-13b show exemplary embodiments having shorter main arms 131, 132 than exemplary embodiments c of FIG. 14a-16b. Exemplary embodiments shown in FIGS. 11a-13b are thus comparable to the exemplary embodiments described in more detail above in relation to FIGS. 6a-7c and figs. 10a-d. The exemplary embodiments of FIG. 14a-16b are comparable to the exemplary embodiments of FIGS. 8a-9c.

In the exemplary embodiments of FIGS. 11a-13b, the pivot point 114 of the inner main arm 132 is located in the area of the projecting housing section 112. In the exemplary embodiments of FIGS. 14a-16b, both pivot points 114 of the main arms 131, 132 are located outside this housing section 112, however, the inner main arm 132 extends within this housing section 112 at least in the closed state of the hinge 10.

In all cases, the geometry and mounting of the main arms 131, 132 allow the housing 111 to be stepped and leave a wide remaining edge 7, for example for the illustrated dowels 8 behind the housing section 112. In addition, the shapes of the main arms 131, 132 are adapted to each other in the exemplary embodiments, so that in the open state of the hinge they are pressed against each other completely or over wide areas, so that the maximum possible opening angle is achieved, and the stop is also determined.

In fig. 11a-16b show only the main arms 131, 132. Possible extensions of the main arms 131, 132 or additional control arms associated therewith that are used to actuate dampers and/or compression springs are not shown in these drawings, but may be present for providing the damping or holding closed function described above or maintaining open functionality.

Instead of the 4-bar mechanisms described in the exemplary embodiments, other multi-link mechanisms, for example 7-bar mechanisms, can also be used according to the invention.

The furniture door 9 may also be formed as a panel that is disposed on a frame, for example a glass panel having at least a partially circumferential aluminum frame. In this case, the second hinge part 12 in the form of a hinge bowl 121 is built into or integrated into the door frame.
