Exemplary embodiments of the invention relate to a hinge for a furniture door, in which a first hinge part is formed having a cassette-shaped housing for integration into a furniture panel, and a second hinge part in the form of a hinge pot to be incorporated into the furniture door, wherein the two hinge parts are pivotably connected to one another via a lever mechanism and wherein at least one damper for opening and closing damping is arranged in the first hinge part. Exemplary embodiments of the invention furthermore relate to a furniture carcass in which at least one such hinge is integrated.
Hinges are used for guiding a door pivoting around a vertical axis in the furniture domain. An advantageous combination of a rotating and sliding movement of the linked furniture door may be achieved using a 7-joint hinge, which permits installation with small gap dimension in relation to adjacent and directly abutting furniture carcasses, which are also equipped with doors, flaps, or drawers, without collisions occurring during the opening of the furniture door. Hinges are frequently 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 pot, which is incorporated into the inner surface of the furniture door. These hinges have the disadvantage that they obstruct a free and arbitrary design of the interior of the furniture carcass.
This disadvantage can be overcome by hinges of the type mentioned at the outset, in which the first hinge part is formed cassette-shaped and sufficiently flat that it can be inserted into a furniture panel, for example a top or bottom panel of the furniture carcass, in a corresponding recess.
Such a door hinge is known, for example, from the document WO 2016/174071 A1. The hinge has an essentially rectangular housing cassette in the top view of the plane in which the lever mechanism is located, which extends on the attachment side of the furniture door up to close to the edge of the bottom. A mechanism for opening and closing damping and a spring mechanism which holds the hinge in the closed state are arranged in the interior of the first hinge part. The hinge has the disadvantage that the first hinge part inserted into the top or bottom panel of the furniture carcass claims the front corner region of the furniture carcass for itself, so that connecting elements cannot be arranged between the top or bottom panel and a side part of the furniture carcass in the region of the hinge. Only adhesive bonding of a side panel to a narrow web of the top or bottom panel which still remains adjacent to the hinge is possible. On the one hand, the stability of the furniture carcass can thus be impaired and, on the other hand, the hinge can only be used in furniture carcasses in which a connection between top or bottom panel and side part is adapted accordingly, so that a recess in which the hinge part is inserted does not collide with connecting elements.
Accordingly, exemplary embodiments of the present invention are directed to a hinge integratable into a horizontal panel of a furniture carcass of the type mentioned at the outset, which does not restrict a use of typical connecting elements between the panel and a side wall of the furniture carcass.
A hinge according to the invention of the type mentioned at the outset is distinguished in that the housing of the first hinge part is widened in a front region, in which an opening for the lever mechanism is located, in relation to a rear region, wherein at least a part of the lever mechanism occupies a space in the front widened region in a closed position of the hinge.
In a view of the plane in which the lever mechanism is located, the housing of the first hinge part is thus formed stepped, for example. Only the region in which the housing is open toward the front and through which the lever of the lever mechanism extends between the first and the second hinge part is embodied wide and extends up to close to the edge of the furniture panel. In a region located behind this, the housing is formed narrower, so that a wider section of the furniture panel remains, which stabilizes the furniture panel in this region, on the one hand, and offers the option, on the other hand, of arranging connecting elements, e.g., dowels, screws, or eccentric connectors. The housing thus has a housing section which protrudes less deeply into the furniture panel than a remaining main section of the housing. The housing section itself has a depth of approximately 10 to 20 mm.
In a typical use of the hinge, the furniture panel is a horizontally aligned panel, for example, a top or intermediate or bottom panel of the furniture carcass. The top or intermediate or bottom panel in which the hinge is inserted can be connected to a side wall of the furniture carcass using the connecting elements. The special embodiment of the housing of the hinge thus enables the furniture carcass to be produced in conventional connection technology or the hinges according to the invention to be integrated into a furniture carcass thus produced. At least one connecting element is arrangeable in the furniture panel for connection to a further component of a furniture carcass in the installation space behind the widened region of the housing and in front of the end of the rear region of the housing.
In one advantageous embodiment of the hinge, the lever mechanism comprises an outer main lever and an inner main lever, which are rotatably linked on the housing of the first hinge part, on the one hand, and are rotatably linked on the hinge pot of the second hinge part, on the other hand. The main levers form the joint mechanism of the hinge, designed in particular as a 4-joint or 7-joint hinge.
The housing section that widens the housing laterally in the front region is preferably formed so that the inner main lever is located at least partially inside this housing section at least in a closed end position of the hinge. This is based on the finding that the housing does not have to penetrate equally deep into the furniture panel everywhere, but does not have to be formed as deep in particular in the edge region in which the main levers of the lever mechanism extend, whereby the above-mentioned free space is provided for the connecting elements. In one embodiment, the inner main lever is rotatably mounted inside the housing and in particular also inside the mentioned housing section.
In a further advantageous embodiment of the hinge, the front widened region faces in the direction of the end of the furniture door on which the hinge pot is arranged. The lever mechanism also extends at this end, which can accordingly enter at least partially into this housing section. The hinge pot can protrude beyond the front widened region in the closed state in the direction of the end of the furniture door, on which the hinge pot is arranged.
In a further advantageous embodiment of the hinge, at the front end of the housing, a contour is arranged as an insertion limit for the installation of the housing in the furniture panel. A fastener for connecting the housing to the furniture panel can be arranged on the contour. Moreover, the contour is preferably formed circumferentially around the front housing end of the housing and overlaps a part of an end face of the furniture panel. The contour can thus be used for fastening the hinge and conceals gaps between the hinge and the furniture panel for optical and hygienic reasons.
In a further advantageous embodiment of the hinge, a damper is provided as a functional part for a closing and/or opening damping in the first and/or in the second hinge part. The damper can be a linear damper, which is designed as a tension or pressure damper or also a rotation damper. The damper preferably interacts directly or indirectly with the lever mechanism at least sometimes.
In one advantageous embodiment of the hinge, at least one of the two main levers is designed as a two-sided lever and is coupled to a damper arranged in the interior of the housing. The movement of the second hinge part is thus transmitted via the levers to the damper to implement the opening and/or closing damping. Because at least one of the main levers is designed as a two-sided lever, the movement of the lever can be transmitted into the interior of the housing, so that the damper can be arranged in the interior of the housing. The movement of the main levers is in such a way that an extreme of the path curve is present, for example, an extension of the outer main lever in a partially open position of the hinge. Both closing and also opening damping can thus be carried out using one damper. However, it is also possible to implement either only a closing or only an opening damping. The damper is preferably a linear damper, which is rotatably fastened with one side on the housing.
In a further advantageous embodiment of the hinge, the damper is linked with its other side directly on an extension of the outer main lever.
Alternatively, an indirect coupling to at least one of the two main levers is also possible. The indirect coupling can be achieved via 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 option of influencing the angle dependence of the damping and thus, for example, adjusting the application points of the damping. A roller can be arranged at the end of the main lever to travel along the control curve.
Indirect coupling can also take place in that a control lever is linked on the outer main lever and on an extension of the inner main lever and is guided at one end along the control curve. A roller can also be provided here to travel along the control curve.
In a further embodiment of the hinge, for the indirect coupling to the main levers, the damper is linked with the free side on two control levers, of which one is linked with its other end on an extension of the outer main lever and the other is linked on an extension of the inner main lever.
In a further advantageous embodiment of the hinge, an elastic force accumulator, in particular a compression spring, for a holding-closed and/or holding-open function is arranged in the housing. Secure closing of the furniture door and/or secure keeping open can thus be achieved, which avoids, for example, a risk of impact on inadvertently partially open doors. Instead of a compression spring, a leaf spring or leg spring can also be used.
The force accumulator is preferably rotatably mounted with one side on the housing and is linked with its other end directly on the extension of the outer main lever. The damper and the force accumulator can be connected in one embodiment of the hinge in a common linkage point with the extension of the outer main lever.
In an alternative embodiment, it is provided that the force accumulator is linked with one side on the extension of the outer main lever and is linked with its other side on the extension of the inner main lever. In both cases, the force accumulator is compressed more strongly in a partially-open position of the hinge than in at least one of the end positions, because of which the force accumulator pre-tensions the hinge in the closed and/or in the open position. Accordingly, both a keeping-closed function for the closed position and also a keeping-open function for the open position of the hinge may be implemented using a force accumulator.
In a further advantageous embodiment of the hinge, the housing of the first hinge part has a greater housing width than housing height in an installed position. The hinge is thus ideally adapted for an installation in a horizontally aligned furniture panel, in particular a top, bottom, or intermediate panel of a furniture carcass. 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.
A furniture carcass according to the invention is distinguished in that at least one such hinge is integrated in a panel of the furniture carcass. The advantages mentioned in conjunction with the hinges result. The panel can be a top, bottom, or intermediate panel.
The invention is explained in greater detail hereinafter on the basis of exemplary embodiments with the aid of figures. In the figures:
An example of a furniture carcass 1 having a furniture door 9 is shown in an isometric view in each of
By way of example, the carcass of a cabinet which is not very deep, for example, a wall unit, is shown as the furniture carcass 1. It is obvious that the illustrated furniture carcass 1 is solely an example of the use of a hinge according to the application and the hinge can be used in other furniture carcasses or pieces of furniture having a furniture door.
The furniture carcass 1 comprises two panels 2, a top panel and a bottom panel. These are arranged between two side walls 3. The furniture carcass 1 furthermore has a rear wall 4.
A furniture door 9 attached on the left side is provided in the example of
Terms used in the context of the description such as “top”, “bottom”, “left”, “right” each relate to the exemplary illustration in the relevant figure. In contrast, the terms “front” and “back” relate to the furniture carcass 1, wherein the front side of the furniture carcass is the side facing toward the user, which is closed by the furniture door 9.
The furniture door 9 is shown in
As is apparent in
The hinge 10 has a first hinge part 11, which is coupled via a lever mechanism 13 to a second hinge part 12. Both hinge parts 11, 12 can be pivoted in relation to one another via the lever mechanism 13.
The first hinge part 11 is incorporated essentially flush—possibly except for a circumferential contour—into the panel 2. For this purpose, the panel 2 has a corresponding recess 5, which is milled into the panel 2, for example. The second hinge part 12 is designed in the form of a hinge pot and is incorporated flush into the furniture door 9 possibly except for the mentioned contour, which can rest like a collar on the surface of the end face of the panel 2.
The first hinge part 11 has an essentially cassette-shaped flat housing, the thickness of which is designed so that the recess 5 can be introduced into the panel 2 without it breaking out on the top, intermediate, or bottom side during the milling of the recess 5. At typical thicknesses of the panels 2 in the range of approximately 15-25 millimeters (mm), the housing of the first hinge part 11 has a thickness, for example, in the range of approximately 9-15 mm. As
Due to this step, a significantly wider edge 7 remains adjacent to the rear region of the first hinge part 11 from the panel 2 than in the front region. The front region, in which the first hinge part 11 is wider, extends over a depth in the range of approximately 10-20 mm. The remaining edge 7 located behind it stabilizes the panel 2 in this region and can advantageously be used to accommodate connecting elements between the panel 2 and the side wall 3. In the example shown, dowel holes 6 corresponding to one another are introduced into the panel 2 and the side wall 3, in which concealed dowels 8 are inserted. It is obvious that alternative connecting elements such as screws, slats, or eccentric connectors can be used instead of or in addition to the mentioned dowels.
Further dowel holes 6 are provided in the rear region of the recess 5. These accommodate dowel elements which are installed on the first hinge part 11 and are used for fastening the first hinge part 11 in the panel 2.
A top view from above of the furniture carcass 1 is shown in
On the other hand, the position of the recess 5 can be recognized on the basis of the concealed lines. Dowels 8 are provided in the front region adjacent to the recess 5 in the remaining edge 7 between panel 2 and side wall 3 as already apparent from
A first exemplary embodiment of a hinge 10 is shown in greater detail in
The hinge 10 is shown in an isometric illustration in a closed or open state, respectively, in
The first hinge part 11 has a cassette-shaped housing 111, having two plates arranged parallel to one another, between which components of the hinge 10 are arranged. The housing can be in multiple parts and can be formed, for example, by two half shells. Sides of the housing 111 are formed rounded in the form of semicylinders to adapt the shape of the housing 111 to the shape of milled openings in the panel 2 of the furniture carcass 1. The housing 111 can thus be inserted precisely fitted into the milled recess 5 (cf.
The second hinge part 12 has a hinge pot 121, also synonymously referred to as a pot housing 121 hereinafter, which is embodied as L-shaped in the present example and comprises a transverse section 122. Protruding fastening tabs 123 having fastening holes are provided at both ends of the pot housing 121, which is L-shaped in this example. Instead of the L shape, the hinge pot can also have another shape.
The tabs 123 rest on the surface of the furniture door 9 and can be fastened via screws on the furniture door 9. Otherwise, the pot housing 121 including its transverse section 122 is incorporated into the material of the furniture door 9. The sides of the pot housing 121 are rounded in the form of semicylinders as in the housing 111 to be able to be inserted in a precisely fitted manner into a corresponding milled opening of the furniture door 9.
Adjustment elements can be arranged in the housing 111 and also the pot housing 121 to be able to adjust a lateral, depth, and/or vertical position of the furniture door 9. The location of the furniture door 9 relative to the furniture carcass 1 can be adjusted using these adjustment elements, for example, to be able to align the furniture door in relation to adjacent furniture fronts.
In the illustrations of
A rotatable mounting of a component (for example the main lever here), which is fixed in relation to the housing 111 and thus fixed in relation to the furniture carcass 1, is referred to as a pivot point in the context of the application. Rotation mountings that are not fixed in relation to the housing 111, for example, because they are located on a lever movable in turn, inter alia, are referred to as linkage points. It is obvious that both a pivot point and also a linkage point can be implemented in various ways, for example, in the form of axles, rivets, bolts, etc.
The main levers 131, 132 are rotatably mounted in linkage points 124 on the side of the second hinge part 12. As a result of the formation as a 4-joint hinge, the second hinge part 12 executes a rotating and sliding movement relative to the first hinge part 11. For reasons of simpler illustration, the combined rotating and sliding movement is referred to as a pivot movement in the context of this application. The shaping of the main levers 131, 132 is such that in the open state of the hinge 10, they can press against one another as precisely fitted as possible. The largest possible opening angle is thus achieved and at the same time a stop is defined for the open position of the hinge 10.
In
In the hinge 10, the outer main lever 131 is formed 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 protrudes into the interior of the housing 111.
A damper 14 is arranged in the housing 111, formed in the present case as a linear damper having 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 at one end, in the present case the end of the cylinder 141, in a pivot point 115 to the housing 111. In addition to the rotation around the pivot point 115, a rotation around an axis perpendicular thereto is enabled by a pivot joint 142. This rotation is relevant, for example, if the hinge 10 offers an adjustment option for a vertical position of the furniture door 9, which takes place via an inclination adjustment of the lever mechanism 13 and in particular of the outer main lever 131. In this case, a pivot joint 144 is also provided at the end of the piston rod. The piston rod 143 is linked via this pivot joint 144 to a linkage point 145 at the end of the extension 133 of the outer main lever 131.
Furthermore, a compression spring 15, which is rotatably mounted in a pivot point 116 with one end fixed in relation to the housing 111, is arranged as an energy or force accumulator in the housing 111. At the other end, the compression spring 15 is also connected with a linkage point 151 to the extension 133 of the outer main lever 131. In the illustrated exemplary embodiment, the linkage point 145 of the damper 14 and the linkage point 151 of the compression spring 15 coincide. A central linkage 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 or the extension 133 in
In the rear region of the housing 11, two fastening options 118 in the form of screw holes are provided, via which the housing 111 can be fastened in the recess of the panel 2. It is possible to screw screws directly through this fastening option 118 into the panel 2 or also to fasten dowel sections on the housing 111 using the fastening option 118, which dowels engage in corresponding dowel holes 6, as shown in
A second exemplary embodiment of a hinge 10 is shown in
In this exemplary embodiment a damper 14 and a compression spring 15, which interact with an extension 133 of the outer lever 131 are also arranged in the housing 111. However, in contrast to the first exemplary embodiment, the compression spring 15 and the damper 14 are not coupled to the extension 133 in a central shared linkage point. Instead, the compression spring 15 is connected in a linkage point 151 directly to the extension 133, whereas the damper 14 interacts via a control curve lever 146 with the extension 133. For this purpose, an arc-shaped control curve lever 146 is rotatably mounted on the housing 111 at one end in a pivot point 117 and an opposing free end of the control curve lever 146 is connected in the linkage point 145 to the piston rod 143 of the damper 14. A rotatable roller 134, which rolls on a control curve 1461 of the control curve lever 146, is fastened at the free end of the extension 133 of the outer main lever 131.
As a comparison of
As in the first exemplary embodiment, damping is thus achieved upon approaching both end positions and also a holding-closed function in the closed state and a holding-open function in the open state are achieved. In this exemplary embodiment, the angle dependency of the damping effect can advantageously be influenced by the option of the design of the shape of the control curve 1461.
Two further embodiments of a hinge 10 according to the application are shown in
The structure of the hinges 10 of
In the example of
A damper 14 and a compression spring 15 are again arranged in the housing 111. The compression spring 15 is not fixed on both sides on the housing 111 in this exemplary embodiment, thus does not have a fixed pivot point, but rather is connected at both ends in linkage points 151 to the extension 133 of the outer main lever 131 on one side and the extension 135 of the inner main lever 132 on the other side of the compression spring 15.
The damper 14 is connected as before at one side, for example again the side of the cylinder, in a pivot point 115 to the housing 111. The opposite side of the damper 14, in the present case the piston rod, is coupled in a linkage point 145 to the extensions 133, 135, specifically via two control levers 136 placed in between. Both control levers 136 are rotatably connected to the damper 14 in the mentioned pivot point 145. One of the control levers 136 is connected in a linkage point 137 to the end of the extension 133 of the outer main lever 131 and the other in a linkage point 137 to an end of the extension 135 of the inner main lever 132. A dotted movement curve is indicated in
In the example of
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 is fastened on one side in a spring fastening 119 in a longitudinally adjustable manner 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 presses 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, whereby it is compressed. The actuating projection 138 also executes a movement in a direction perpendicular to the axis of the compression spring 15 at the same time, which is enabled because of the roller 152, however. The actuating projection 138 can additionally have a curve contour, via which the deflection of the compression spring 15 can additionally be changed in dependence on the hinge position.
A comparison of
The damper 14 is connected to the housing 111 with one end rotatably in a pivot point 115 in this exemplary embodiment and is coupled at its other end, in the present case the piston rod, to a control curve lever 146, which is two-sided in this exemplary embodiment. This lever is mounted on the housing 111 rotatably in relation thereto in a pivot point 117. A control curve 1461 is formed on the control curve lever 146 in the region in which the roller 139 of the control lever 136 presses against it.
During the opening or closing procedure of the hinge 10 (cf. sequence of
A further exemplary embodiment of a hinge 10 according to the application is again shown in
As in the examples of
The extension 133 of the outer main lever 131 is coupled in this exemplary embodiment in a linkage point 151 to the compression spring 15. The compression spring 15 is articulated with the extension 133 in this linkage point 151 with an end freely laterally movable in the plane of the lever. The other side of the compression spring 15 is pivotably mounted in the housing 111 in a pivot point 116.
The outer main lever 131 and the inner main lever 132 both act on the damper 14. For this purpose, a control curve lever 146 is linked on the inner main lever 132 in a linkage point 147, which acts via a roller lever 148 on the damper 14. Moreover, an angular position of the control curve lever 146 is influenced by the position of the extension 133 of the outer main lever 131. The cooperation of the levers mentioned is explained in greater detail hereinafter.
The damper 14 is fixed with one side, for example with the side of its cylinder 141 here, pivotably in a pivot point 115 in the housing 111. The opposite side of the damper 14, in the present case thus the end of the piston rod 143, is coupled in a linkage point 145 to the roller lever 148. This roller lever 148 is pivotably mounted in 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 rollers 1481, 1482, bolts having outer roundings can also be used. The rollers 1481, 1482 press against control curves 1461, 1462 of the control curve lever 146.
The control curve lever 146 divides at its free end in a fork or claw shape, whereby an inner concave control curve 1461 and an outer convex control curve 1462 are formed. Depending on the open position of the hinge 10, the roller 1481 is in contact with the control curve 1461 and/or the roller 1482 is in contact with the control curve 1462.
Furthermore, a further control curve 1463 is formed on the lower section of the control curve lever 146 in front of the mentioned fork, on which curve a roller 152 contacts, which is rotatably mounted in the linkage point 151 of the compression spring 15 on the extension 133 of the outer main lever 131. The angular position of the control curve lever 146 is determined by the outer main lever 131 due to the rolling of the roller 152 on the further control curve 1463.
Starting points of the damper 14 and a damping force curve can be set deliberately and differently for the closing damping and the opening damping by the positioning of the rollers 1481, 1482 on the roller lever 148 and the shaping of the control curve 1461-1463.
In the position of
In the position of
Six different embodiments of hinges 10 are shown in
Similar to
In the exemplary embodiments of
In all cases, the geometry and mounting of the main levers 131, 132 enable the housing 111 to be formed stepped and a broad remaining edge 7 for, for example, the illustrated dowels 8 to be left out behind the housing section 112. Moreover, the shapes of the main levers 131, 132 are adapted to one another in the exemplary embodiments so that in the open state of the hinge, they press against one another entirely or over broad regions so that the largest possible opening angle is achieved and a stop is also defined.
Only the main levers 131, 132 are shown in
Instead of the 4-joint mechanisms described in the exemplary embodiments, other multi-joint lever mechanisms can also be used according to the invention, for example, 7-joint mechanisms.
The furniture door 9 can also be formed as a panel which is arranged on a frame, for example as a glass panel having an at least partially circumferential aluminum frame. In this case, the second hinge part 12 in the form of the hinge pot 121 is incorporated into the frame of the door or integrated into this frame.
