EP3947874B1 - Furniture carcass having a hinge - Google Patents

Description

The invention relates to a furniture body in which at least one hinge is integrated, according to the preamble of claim 1.

Hinges are used to guide a door that pivots about a vertical axis in the furniture sector. With one or 7-joint hinges, an advantageous combination of a turning and sliding movement of the hinged furniture door can be achieved, which allows assembly with a small gap to adjacent and directly adjacent furniture bodies that are also equipped with doors, flaps or drawers without that collisions occur when the furniture door is opened. Hinges are often used in which a first hinge part is placed on a side wall of the furniture carcass and in which a second hinge part is designed as a hinge cup that is let into the inner surface of the furniture door. The disadvantage of these hinges is that they prevent free and arbitrary design of the interior of the furniture body.

This disadvantage can be overcome by hinges of the type mentioned in which the first hinge part is cassette-shaped and so flat that it is inserted into a corresponding recess in a furniture panel, for example a top or bottom panel of the furniture body.

Such a door hinge is, for example, from the publication WO 2016/174071 A1 known. The hinge has a housing cartridge that is essentially rectangular in the top view of the plane in which the lever mechanism lies, and which extends close to the edge of the floor on the stop side of the furniture door. A mechanism for damping opening and closing as well as a spring mechanism that keeps the hinge in the closed state are arranged inside the first hinge part. The disadvantage of the hinge is that the first hinge part inserted into the top or bottom panel of the furniture body occupies the front corner area of the furniture body, so that connecting elements between the top or bottom panel and a side part of the furniture body in the area of the hinge are not can be arranged. It is only possible to glue a side panel to a narrow web on the top or bottom panel, which remains next to the hinge. On the one hand, this can reduce the stability of the furniture body be affected and on the other hand, the hinge can only be used in furniture bodies in which a connection between the top or bottom panel and side part is adjusted accordingly, so that a recess into which the hinge part is used does not collide with connecting elements.

The pamphlet IT MI20 100 555 A1 also shows a hinge with a cassette-like housing that can be integrated into a furniture panel of a furniture body. The housing is widened in a front area, in which there is an opening for the lever mechanism, compared to a rear area, with at least part of the lever mechanism occupying a space in the front widened area when the hinge is in a closed position. In the edge area of the furniture board, in which the hinge is inserted, a wider section of the furniture board remains, which has an advantageous effect on its stability.

It is an object of the present invention to provide a furniture body with an integrated hinge, in which conventional connecting elements can be used between the floor and a side wall of the furniture body.

This problem is solved by a furniture body with the features of claim 1. Advantageous refinements and developments are the subject matter of the dependent claims.

A furniture body according to claim 1 has a hinge in which a housing of a first hinge part is widened in a front area, in which there is an opening for a lever mechanism, compared to a rear area, with at least part of the lever mechanism being in a closed position of the Hinge occupies a space in the front widened area.

With a view to the plane in which the lever mechanism is located, the housing of the first hinge part is therefore designed in a stepped manner, for example. Only the area in which the housing is open to the front and runs through the lever of the lever system between the first and second hinge part is wide and protrudes close to the edge of the furniture panel. The housing is designed to be narrower in an area behind it, so that a wider section of the furniture panel remains, which covers the furniture panel in this area on the one hand stabilized and in which at least one connecting element for connection to another component of a furniture body is arranged according to the invention. A dowel, a screw or an eccentric connector can be used as a connecting element. The housing thus has a housing section that protrudes less deeply into the furniture panel than a remaining main section of the housing. The housing section itself has a depth of about 10 to 20 mm.

The furniture board is a horizontally aligned floor, e.g. a top, intermediate or underside of the furniture body. With the connecting elements, a connection can be made between the top or intermediate or underside, in which the hinge is inserted, to a side wall of the furniture body. The special design of the housing of the hinge makes it possible to produce the furniture body using the usual connection technology or to integrate the hinges into a furniture body produced in this way. In the space behind the widened area of the housing and in front of the end of the rear area of the housing, the at least one connecting element is arranged in the furniture panel for connection to the other component of the furniture body.

In an advantageous embodiment of the furniture body, the lever mechanism comprises an outer main lever and an inner main lever which are rotatably articulated on the housing of the first hinge part on the one hand and on the hinge cup of the second hinge part on the other hand. The main levers form the linkage of the hinge, in particular designed as a 4-bar or 7-bar linkage.

The housing section, which widens the housing laterally in the front area, is preferably designed in such a way that the inner main lever is located at least partially within this housing section, at least when the hinge is in a closed end position. It is based on the knowledge that the housing does not have to penetrate the same depth into the furniture panel everywhere, but rather does not have to be designed so deeply in the edge area in which the main levers of the lever mechanism run, which creates the aforementioned free space for the connecting elements becomes. In one embodiment, the inner main lever is rotatably mounted within the housing and in particular also within the housing section mentioned.

In a further advantageous embodiment of the furniture body, the widened front area points in the direction of the end of the furniture door on which the hinge cup is arranged. The lever system also runs at this end and can accordingly at least partially enter this housing section. In this case, the hinge cup can protrude beyond the widened front area in the closed state in the direction of the end of the furniture door on which the hinge cup is arranged.

In a further advantageous embodiment of the furniture body, a contour is arranged at the front end of the housing as an insertion limitation for mounting the housing in the furniture panel. A fastening means for connecting the housing to the furniture panel can be arranged on the contour. In addition, the contour is preferably formed circumferentially around the front housing end of the housing and covers part of an end face of the furniture panel. The contour can thus be used to attach the hinge and, for optical and hygienic reasons, covers gaps between the hinge and the furniture panel.

In a further advantageous embodiment of the furniture body, a damper is provided in the first and/or in the second hinge part as a functional part for closing and/or opening damping. The damper can be a linear damper designed as a tension or compression damper, or a rotary damper. The damper preferably interacts directly or indirectly with the lever system, at least at times.

In an advantageous embodiment of the furniture body, at least one of the two main levers is designed as a double-sided lever and is coupled to a damper arranged inside the housing. The movement of the second hinge part is thus transmitted to the damper via the lever in order to realize the opening and/or closing damping. Due to the fact that at least one of the main levers is designed as a two-sided lever, the movement of the levers can be transferred into the interior of the housing, so that the damper can be arranged in the interior of the housing. The movement of the main lever is such that an extremum of the trajectory, for example an extension of the outer main lever, is present when the hinge is in a partially open position. As a result, both closing and opening damping can take place with one damper. However, it is also possible to implement either only a closing or only an opening damping. Preferred the damper is a linear damper with one side rotatably attached to the housing.

In a further advantageous embodiment of the furniture body, the other side of the damper is articulated directly on an extension of the outer main lever.

Alternatively, an indirect coupling with at least one of the two main levers is also possible. The indirect coupling can be achieved via a cam lever, the free end of which is connected to the damper and the other end of which is pivotally connected to the housing. The cam lever has at least one cam along which one end of the at least one main lever is guided. The control curve offers the possibility of influencing the angle dependency of the damping and thus, for example, setting the points at which the damping starts. A roller can be arranged at the end of the main lever in order to follow the cam.

An indirect coupling can also take place by a control lever being articulated to the outer main lever and to an extension of the inner main lever and guided at one end along the control curve. Here, too, a roller can be provided in order to follow the cam.

In another embodiment of the furniture body, the damper is articulated with the free side on two control levers for indirect coupling with the main levers, one of which is articulated with its other end on an extension of the outer main lever and the other is articulated on an extension of the inner main lever .

In a further advantageous embodiment of the furniture body, an elastic energy accumulator, in particular a compression spring, is arranged in the housing for a locking and/or holding open function. In this way, the furniture door can be closed safely and/or kept open safely, which e.g. A leaf or torsion spring can also be used instead of a compression spring.

Preferably, one side of the energy accumulator is rotatably mounted on the housing and its other end is articulated directly on the extension of the outer main lever. The damper and the force accumulator can be an embodiment of the hinge in a common pivot point with the extension of the outer main lever.

In an alternative embodiment, provision is made for the force accumulator to be articulated on one side to the extension of the outer main lever and to be articulated on the other side to the extension of the inner main lever. In both cases, the force accumulator is more strongly compressed in a partially open position of the hinge than in at least one of the end positions, which is why the force accumulator prestresses the hinge in the closed and/or in the open position. With an energy store, both a locking function for the closed position and a hold-open function for the open position of the hinge can be implemented accordingly.

In a further advantageous embodiment of the furniture body, the housing of the first hinge part has a greater housing width than the housing height in an installed position. The hinge is thus ideally adapted to installation in a horizontally oriented furniture panel, in particular a top, bottom or intermediate floor of a furniture body. The housing height of the first hinge part is preferably between 9 and 15 mm, whereas the housing width of the first hinge part is between 30 and 100 mm.

In the Fig. 1a, b an example of a furniture body 1 with a furniture door 9 is shown in an isometric drawing.

By way of example, the body of a shallow cupboard, for example a wall cupboard, is shown as the furniture body 1 .

The furniture body 1 comprises two floors 2, a top floor and a bottom floor. These are arranged between two side walls 3 . The furniture body 1 also has a rear wall 4 .

It is an example of the Figures 1a and 1b provided on the left-hand side hinged furniture door 9, which is pivotally guided by hinges 10. The pivot axis runs parallel and in the area of a front narrow side of the side wall 3 on the left in the figure.

Terms such as "top", "bottom", "left", "right" used in the description relate to the exemplary representation in the relevant figure. The terms “front” and “rear” on the other hand refer to the furniture body 1, the front side of the furniture body being the side facing the user, which is closed by the furniture door 9.

Furniture door 9 is in Fig. 1a in a closed and in Fig. 1b rendered in an open position. The movement of the furniture door 9 guided by the hinges 10 is a combined pivoting and sliding movement, which makes it possible to open the furniture door with a small gap between the furniture door and adjacent furniture. Such a movement of the furniture door 9 is achieved by configuring the hinges 10 as 4-joint hinges.

As in Fig. 1b As can be seen, the hinges 10 are integrated into the respective bottom 2 . In this way, the interior of the furniture body 1 and in particular the side wall 3 remains free of hinge components, so that the interior can be designed freely. In particular, there are no restrictions as to the positions between floors or other division or sorting systems in the furniture body 1 can be arranged.

2 shows a partially sectional plan view of the furniture body 1 with the furniture door 9 open in the area of the hinge 10. The furniture body 1 is shown in section in the area of the hinge 10 in order to gain an insight into the arrangement of the hinge 10 and its geometry within the base 2.

The hinge 10 has a first hinge part 11 which is coupled to a second hinge part 12 via a lever mechanism 13 . About the lever mechanism 13 both hinge parts 11, 12 can be pivoted to each other.

The first hinge part 11 is essentially flush--possibly embedded in the floor 2 except for a peripheral contour. The base 2 has a corresponding recess 5 for this purpose, which is milled into the base 2, for example. The second hinge part 12 is designed in the form of a hinge cup and, if necessary, except for the mentioned contour, which is like a collar on the surface the end face of the floor 2 can rest, flush with the furniture door 9 embedded.

The first hinge part 11 has an essentially cassette-shaped, flat housing, the thickness of which is designed such that the recess 5 can be introduced into the base 2 without the latter breaking open on the upper, intermediate or lower side when the recess 5 is milled. With typical thicknesses of the floors 2 in the range of approximately 15-25 millimeters (mm), the housing of the first hinge part 11 has a thickness in the range of approximately 9-15 mm, for example. As the 2 shows, the housing of the first hinge part 11 is wider in a front area, which extends to the narrow edge of the base 2, than in a rear area, with which the first hinge part 11 protrudes deeper into the base 2. The housing of the first hinge part 11 is therefore stepped in this horizontal plane, in which the base 2 lies and in which the lever mechanism 13 lies.

As a result of this step, next to the rear area of the first hinge part 11, a significantly wider edge 7 remains on the floor 2 than in the front area. The front area, in which the first hinge part 11 is wider, extends over a depth in the range of about 10-20 mm. The remaining edge 7 behind it stabilizes the base 2 in this area and can be used advantageously to accommodate connecting elements between the base 2 and the side wall 3 . In the example shown, dowel holes 6 corresponding to one another are made in the base 2 and the side wall 3, into which concealed dowels 8 are inserted. It goes without saying that alternative connecting elements such as screws, lamellae or eccentric connectors can be used instead of or in addition to the dowels mentioned.

More dowel holes 6 are provided in the rear area of the recess 5 . These take on dowel elements that are mounted on the first hinge part 11 and are used to fasten the first hinge part 11 in the floor 2 .

In Figure 3a is a plan view from above of the furniture carcass 1, with hidden lines being shown in dashed lines. In the Figure 3a only the furniture body 1 without a hinge 10 and without a furniture door 9 is shown. On the one hand, the hidden lines show the rear wall, which extends into the side walls 2 and can also serve as a connecting element between the side wall 3 and the base 2 . Alternatively or additionally 3 dowels can also be used in the rear area of the furniture body 1 between the floor 2 and the side wall.

On the other hand, the position of the recess 5 can be seen from the hidden lines. Dowels 8 are like out 2 already visible in the front area next to the recess 5 in the remaining edge 7 between the bottom 2 and side wall 3 is provided. At the same position, such dowels 8 are also arranged in dowel holes 6 in order to connect the base 2 to the opposite side wall 3 .

The Figure 3a shows that due to the stepped design of the housing of the first hinge part 11 and the resulting edge 7, the same connection technique can be used between the base 2 for both side walls 3. In other words, a conventional connection technique that has become established in furniture bodies 1 between the floor 2 and side wall 3 can also be used when the embedded hinge 10 is used.

Figure 3b shows the edge area of the furniture body 1 with the recess 5 enlarged again and in more detail in a sectional view, the section being made in a plane parallel to the surface of the floor 2.

In the Figures 4a-6c a first embodiment of a hinge 10 is shown in more detail.

In the Figures 4a and 4b the hinge 10 is shown in an isometric representation in a closed and open state. The Figures 5a and 5b 12 show top views of the hinge 10, also in the closed or open state.

The first hinge part 11 has a cassette-shaped housing 111 with two plates arranged parallel to one another, between which the components of the hinge 10 are arranged. The housing can be in several parts and can be formed, for example, by two half-shells. Sides of the housing 111 are rounded in the form of half cylinders in order to adapt the shape of the housing 111 to the shape of cutouts in the bottom 2 of the furniture body 1. The housing 111 can thus fit precisely into the milled recess 5 (cf. 2 ) are used. The section protruding on one side of the housing 111 in the front area is identified by the reference number 112 in the figures. The housing section 112 is on the side of the housing 111 arranged on which the lever mechanism 13 in the open position ( Figure 4b ) exits the housing 111.

The second hinge part 12 has a hinge pot 121 , also referred to as a synonym pot housing 121 below, which is L-shaped in the present example and includes a transverse section 122 . At both ends of the pot-shaped housing 121, which is L-shaped in this example, protruding fastening lugs 123 with fastening bores are provided. Instead of the L-shape, the hinge cup can also have a different shape.

The tabs 123 rest on the surface of the furniture door 9 and can be attached to the furniture door 9 using screws. Otherwise the pot housing 121 including its transverse section 122 is embedded in the material of the furniture door 9 . The sides of the cup-shaped housing 121 are rounded off in the form of half cylinders, just like the housing 111, so that they can be inserted with a precise fit into a corresponding cutout in the furniture door 9.

Adjustment elements can be arranged in the housing 111 and also in the pot housing 121 in order to be able to adjust a lateral, depth and/or height position of the furniture door 9 . The position of the furniture door 9 relative to the furniture body 1 can be adjusted with these adjustment elements, e.g. in order to be able to align the furniture door with respect to adjacent furniture fronts.

In the representations of Figures 5a, 5b the housing 111 is shown broken away in the area of the housing section 112, as is the pot housing 121, in order to show the arrangement of the lever mechanism 13 in this area. The lever system has an outer main lever 131 and an inner main lever 132 as a 4-bar linkage. These are rotatably articulated on a carrier 113 which is arranged in the area of the housing section 112 . The carrier 113 provides two pivot points 114 on which the main levers 131, 132 are mounted.

In the context of the application, a rotatable mounting of a component (here, for example, the main lever) is referred to as a fulcrum, which is stationary with respect to the housing 111 and thus stationary with respect to the furniture body 1 . Pivot bearings that are not stationary to the housing 111, for example because they are located on a lever or the like that is moved on its part, are referred to as pivot points. It is understood that both a pivot point and a pivot point on different Types can be realized, for example in the form of axles, rivets, bolts, etc..

On the side of the second hinge part 12, the main levers 131, 132 are rotatably mounted in pivot points 124. As a result of the design as a 4-joint hinge, the second hinge part 12 performs a rotating and sliding movement relative to the first hinge part 11. For reasons of simplicity, the combined rotating and sliding movement is referred to as a pivoting movement in the context of this application. The shape of the main levers 131, 132 is such that when the hinge 10 is in the open state, they can fit together as precisely as possible. In this way, the largest possible opening angle is achieved and at the same time a stop for the open position of the hinge 10 is defined.

In the Figures 6a-6c Figure 1 shows the hinge 10 in a sectional view taken just below the top panel of the housing 111 so that the internal structure of the hinge 10 can be seen. The figures show an opening sequence of the hinge 10 shown in Figure 6a in the closed, in the Figure 6b in a partially open and in Figure 6c is shown in a fully open position.

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

A damper 14 is arranged in the housing 111, in the present case designed as a linear damper with a cylinder 141, in which a piston (not visible here) moves in a damped manner and which is connected to a piston rod 143. The damper 14 is connected to the housing 111 at a pivot point 115 at one end, in this case the end of the cylinder 141 . In addition to the rotation about the pivot point 115, a rotation about an axis perpendicular thereto is also made possible by a rotary joint 142. This rotation is relevant, for example, when the hinge 10 offers an adjustment option for a height position of the furniture door 9, which takes place via an inclination adjustment of the lever system 13 and in particular of the outer main lever 131. In that case, a swivel joint 144 is also provided at the end of the piston rod. The piston rod 143 is articulated via this swivel joint 144 with an articulation point 145 at the end of the extension 133 of the outer main lever 131 .

Furthermore, a compression spring 15 is arranged in the housing 111 as an energy or force storage device, one end of which is rotatably mounted at a pivot point 116 so as to be stationary with respect to the housing 111 . At the other end, the compression spring 15 is also connected to the extension 133 of the outer main lever 131 by a pivot point 151 . In the illustrated embodiment, the pivot point 145 of the damper 14 and the pivot point 151 of the compression spring 15 coincide. A central pivot point is thus formed between the end of the extension 133, the damper 14 and the compression spring 15.

As a comparison of the positions of the outer main lever 131 and the extension 133 in the Fig. 6a-c shows, the central pivot point 145, 151 performs a pivoting movement in such a way that the damper 14 is in an intermediate position (cf. Figure 6b ) relative to both end positions (completely closed or completely open) is further extended, whereas the compression spring 15 is more compressed in the intermediate position than in the end positions. In this way, a damping of both the approach to the closed as well as to the open end position is achieved. Furthermore, due to the compression spring 15, the hinge 10 is prestressed both in the closed position and in the open position, whereby a locking or holding-open function is achieved.

In the rear area of the housing 11 there are two fastening options 118 in the form of screw holes, via which the housing 111 can be fastened in the recess in the base 2 . It is possible to screw screws directly into the base 2 through this attachment option 118 or to attach dowel sections to the housing 111 with the attachment option 118, which engage in corresponding dowel holes 6, as shown in 2 is shown.

In the Figures 7a-7c is in the same way as in the Figures 6a-6c a second embodiment of a hinge 10 is shown. In these figures and in the following figures, the same reference symbols designate elements that are the same or have the same effect as in the first exemplary embodiment. With regard to the basic structure of the hinge 10, reference is made to the first exemplary embodiment. In particular, the housing shape of the housing 111 with the housing 111 widened only in the front area is also implemented by the housing section 112 in these and the following exemplary embodiments.

In this exemplary embodiment, too, a damper 14 and a compression spring 15 are arranged in the housing 111 and interact with an extension 133 of the outer lever 131 . In contrast to the first exemplary embodiment, however, the compression spring 15 and the damper 14 are not coupled to the extension 133 at a central common articulation point. Instead, the compression spring 15 is connected directly to the extension 133 at an articulation point 151 , whereas the damper 14 interacts with the extension 133 via a cam lever 146 . For this purpose, an arcuate control cam lever 146 is rotatably mounted at one end in a pivot point 117 on the housing 111 and an opposite free end of the control cam lever 146 is connected at the pivot point 145 to the piston rod 143 of the damper 14. A rotatable roller 134 is attached to the free end of the extension 133 of the outer main lever 131 and rolls on a cam 1461 of the cam lever 146 .

Like comparing the Fig. 7a-c shows the opening sequence of the hinge 10, the compression spring 15 is also in an intermediate position in this embodiment (cf. Figure 7b ) compressed more than in the end positions, whereas the damper 14 is more extended in the intermediate position than in the end positions.

As in the first exemplary embodiment, damping is achieved when both end positions are approached, and a locking function is achieved in the closed state and a hold-open function in the open state. Due to the possibility of designing the shape of the control curve 1461, the angular dependency of the damping effect can advantageously be influenced in this exemplary embodiment.

In the Fig. 8a-c and 9a-c are two other configurations of a hinge 10 in a similar manner as in the Fig. 6a-c and 7a-c played back. The Fig. 8a-c and 9a-c are somewhat more schematic in contrast to the figures described above and show the hinge 10 in an installation situation in a furniture body which is arranged adjacent to another furniture body. A side wall 3 and a furniture door 9 of the further furniture body are shown.

Basically corresponds to the structure of the hinges 10 of Fig. 8a-c and 9a-c those of the exemplary embodiments described above, to which explicit reference is hereby made. In contrast to the exemplary embodiments described above, the outer main lever 131 and the inner main lever 132 are longer designed than in the previous exemplary embodiments, as a result of which the pivot points 114 are no longer in the area of the housing section 112, but further in the main section of the housing 111. However, at least the inner main lever 132 leads through the housing section 112.

In the example of Fig. 8a-c both main levers 131, 132 are extended inside the housing 111. In addition to the extension 133 of the outer main lever 131, an extension 135 of the inner main lever 132 also projects into the housing 111.

A damper 14 and a compression spring 15 are in turn arranged in the housing 111 . In this exemplary embodiment, the compression spring 15 is not fixed to the housing 111 on both sides, i.e. it does not have a fixed pivot point, but is located at both ends in pivot points 151 with the extension 133 of the outer main lever 131 on one and the extension 135 of the inner main lever 132 the other side of the compression spring 15 connected.

As before, the damper 14 is connected to the housing 111 at a pivot point 115 on one side, for example again on the side of the cylinder. The opposite side of the damper 14, in this case the piston rod, is coupled to the extensions 133, 135 at a pivot point 145 via two control levers 136 placed between them. One of the control levers 136 is connected at a pivot point 137 to the end of the extension 133 of the outer main lever 131 and the other at a pivot point 137 to one end of the extension 135 of the inner main lever 132. In den Fig. 8a-c a dotted movement curve is indicated, which the pivot point 145 undertakes in the course of an opening or closing movement. As in the previously described exemplary embodiments, the compression spring 15 is more strongly compressed in an intermediate position of the hinge compared to the end positions, whereas the damper 14 is deflected further. There is a damping at each of the end positions by the damper 14 and a locking or holding open function by the compression spring 15.

In the example of Fig. 9a-c the damper 14 and the compression spring 15 are coupled to the two main levers 131, 132 via an additional control lever 136. This is articulated at one end in a pivot point 137 to the outer main lever 131. An extension of the main lever 131 (see. Extension 133 in the previously illustrated embodiments) is not required in this embodiment. On the other hand, the inner main lever is similar to the example of the Fig. 8a-c designed as a two-sided lever and has an extension 135 accordingly. The control lever 136 is coupled to this extension 135, which is good for enlarging the corresponding detail in Figure 9a is recognizable. This coupling has an articulation point 137 on the extension 135, which is guided in the control lever 136 in a slot 137', which in this sense also represents a control curve.

The control lever 136 ends on the one hand in an actuating projection 138 and on the other hand in a roller 139. The actuating projection 138 interacts with the compression spring 15, which in this exemplary embodiment is fastened to the housing 111 in a spring fastening 119 in a length-adjustable manner on one side. The opposite free end of the compression spring 15 is also provided with a roller 152 which rests against the actuating projection 138 of the control lever 136. During an opening or closing movement of the hinge 10, the actuating projection 138 moves in the direction of the compression spring 15, as a result of which the latter is compressed. The actuating projection 138 also performs a movement in a direction perpendicular to the axis of the compression spring 15, which, however, is made possible by the roller 152. The actuating projection 138 can also have a curved contour via which the deflection of the compression spring 15 can also be changed as a function of the hinge position.

A comparison of Fig. 9a-c shows that in this exemplary embodiment, too, the compression spring 15 is in an intermediate state (see Figure 9b ) is compressed more than in at least one end position, whereby the locking function and/or the hold-open function in the closed or open end position is achieved again.

In this exemplary embodiment, the damper 14 is rotatably connected at one end to the housing 111 at a pivot point 115 and is coupled at its other end, in this case the piston rod, to a double-sided cam lever 146 in this exemplary embodiment. This is rotatably mounted on the housing 111 at a pivot point 117 in relation to the housing 111 . A cam 1461 is formed on the cam lever 146 in the area in which the roller 139 of the cam lever 136 rests.

During the opening and closing process of the hinge 10 (cf. the sequence of Fig. 9a-c ) the roller 139 at the end of the control lever 136 moves along the control cam 1461 of the control cam lever 146, as a result of which the movement of the main levers 131, 132 is transmitted to the damper 14. There is a comparison with the end positions further deflection of the damper 14 in the intermediate position of the Figure 9b reached. Correspondingly, when the damper 14 is retracted, damping is achieved when each of the two end positions is approached.

In the Fig. 10a-d is another embodiment of a hinge 10, again in a manner comparable to that in FIGS Fig. 6a-c and 7a-c shown. Here, too, the structure of the hinge 10 basically corresponds to that of the exemplary embodiments shown above, to which explicit reference is hereby made. The differences from the previously described exemplary embodiments are explained in particular below.

As with the examples of Fig. 6a-c and 7a-c , pivot points 114 of both main levers 131, 132 are not in the main section of the housing 111, but in or in front of the housing section 112. Furthermore, the outer main lever 131 is also extended into the main section of the housing 111 as a two-sided lever.

The extension 133 of the outer main lever 131 in this exemplary embodiment couples to the compression spring 15 at a pivot point 151. The compression spring 15 is articulated to the extension 133 at this pivot point 151 with an end that is 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 lever 131 and the inner main lever 132 act on the damper 14 . For this purpose, a cam lever 146 is articulated at a pivot point 147 on the inner main lever 132 and acts on the damper 14 via a roller lever 148 . In addition, an angular position of the cam lever 146 is influenced by the position of the extension 133 of the outer main lever 131 . The interaction of the levers mentioned is explained in more detail below.

One side of the damper 14 , here by way of example the side of its cylinder 141 , is pivotable at a pivot point 115 in the housing 111 . The opposite end of the damper 14, in this case the end of the piston rod 143 is coupled to the roller lever 148 at a pivot point 145 . This roller lever 148 is mounted pivotably on the housing 111 at a pivot point 149 .

The roller lever 148 is in the form of a plate on which two rollers 1481, 1482 are rotatably mounted. Instead of rollers 1481, 1482, bolts with external curves can also be used. The rollers 1481, 1482 rest on cams 1461, 1462 of the cam lever 146.

The cam lever 146 is divided at its free end in the form of a fork or claw, as a result of which an inner concave cam 1461 and an outer convex cam 1462 are formed. Depending on the open position of the hinge 10, the roller 1481 is in contact with the cam 1461 and/or the roller 1482 is in contact with the cam 1462.

Furthermore, another control cam 1463 is formed on the lower section of the control cam lever 146 in front of said fork, which is contacted by a roller 152, which is rotatably mounted at the pivot point 151 of the compression spring 15 on the extension 133 of the outer main lever 131. The angular position of the cam lever 146 is determined by the outer main lever 131 by the rolling of the roller 152 on the further cam 1463 .

The positioning of the rollers 1481, 1482 on the roller lever 148 and the shape of the control cam 1461-1463 enable the activation points of the damper 14 and a damping force profile to be adjusted specifically and differently for the closing damping and opening damping.

Figure 10a shows the hinge 10 in a closed state. Here the compression spring 15 is maximally relaxed and the damper 14 is almost completely retracted, with the power transmission between the cam lever 146 and the damper 14 taking place via contact between the roller 1482 and the outer cam 1462 .

The Figures 10b and 10c show the hinge in two different partially open positions.

At the position of Figure 10b the transition between self-closing or closing damping and self-opening or opening damping is taking place. The compression spring 15 is maximally tensioned in this state and the damper 14 fully extended. In this position, both rollers 1481, 1482 are in contact with the respective cam 1461, 1462.

At the position of Figure 10c then there is a transition to the exclusive contact of the roller 1481 with the inner cam 1461 for backcheck. At the maximum open position according to Figure 10d then the damper 14 is almost completely retracted and the compression spring is slightly relaxed. The difference in spring tension in the closed position according to Figure 10a and the opening position in Figure 10b requires a self-opening with less force than is the case with self-closing.

In the Figures 11a-16b six different configurations of hinges 10 are shown, which differ in the shape of the main levers 131, 132. The figures with the suffix "a" show the hinge 10 in a closed position and the figures with the suffix "b" show the same hinge in an open position.

Similar to the Fig. 8a-c and 9a-c are the hinges 10 in the Figures 11a-16b in an installation situation, a furniture body 1 with a door 9 is shown, which is arranged adjacent to another furniture body, of which a side wall 3 and a door 9 are shown.

The Figures 11a-13b show embodiments with shorter main levers 131, 132 than the embodiments in FIGS Figures 14a-16b . The exemplary embodiments Figures 11a-13b are thus comparable to the exemplary embodiments of FIG Figures 6a-7c and Fig. 10a-d . The exemplary embodiments Figures 14a-16b are comparable to the embodiments of Figures 8a-9c .

In the embodiments of Figures 11a-13b is the pivot point 114 of the inner main lever 132 in the area of the protruding housing section 112. In the exemplary embodiments of FIG Figures 14a-16b Both pivot points 114 of the main levers 131, 132 lie outside this housing section 112, but the inner main lever 132 runs within this housing section 112, at least when the hinge 10 is in the closed state.

In all cases, the geometry and mounting of the main levers 131, 132 make it possible to form the housing 111 in a stepped manner and behind the housing section 112 to have a wide remaining edge 7 for, for example, the dowels shown 8 to spare. In the exemplary embodiments, the shapes of the main levers 131, 132 are also adapted to one another so that when the hinge is in the open state they rest against one another completely or over large areas in such a way that the largest possible opening angle is achieved and a stop is also defined.

In the Figures 11a-16b only the main levers 131, 132 are shown. Any extensions of the main levers 131, 132 or other control levers connected to them, which are used to actuate dampers and/or compression springs, are not shown in these figures, but can be present in order to provide the previously described damping functionality or locking or holding functionality offer.

Instead of the 4-joints described in the exemplary embodiments, other multi-joint lever systems can also be used, such as 7-joints.

The furniture door 9 can also be designed as a panel which is arranged on a frame, for example as a glass panel with an at least partially circumferential aluminum frame. In this case, the second hinge part 12 in the form of the hinge cup 121 is let into the frame of the door or is integrated into this frame.
