The invention relates to a furniture hinge comprising a carcass hinge part that can be fastened to a furniture carcass, a door leaf hinge part that can be fastened to a door leaf, and at least one articulated lever for the articulated connection of the carcass hinge part to the door leaf hinge part, wherein the articulated lever is connected to a hinge arm of the carcass hinge part such that it can pivot around a pivot axis and the hinge arm can be adjusted for the depth adjustment of the door leaf in reference to the furniture carcass in the longitudinal direction in reference to a retaining part of the carcass hinge part, with the hinge arm being adjustable in reference to the retaining part for depth adjustment via an eccentric acting between the hinge arm and the retaining part.
For the depth adjustment of a furniture hinge it is known to adjust the hinge arm of the carcass hinge part, at which at least one articulated lever of the furniture hinge is mounted in a pivotal manner, in reference to the retaining part of the carcass hinge part in the longitudinal direction of the hinge arm. For this purpose, in conventional hinges of the type mentioned at the outset, a type of clamping screw, which penetrates an oblong slot in the hinge arm and is screwed into a threaded bore of the retaining part, is loosened and retightened after the desired adjustment of the hinge arm. Here, it is disadvantageous that the door leaf must be held in the adjusted position of the hinge arm when the clamping screw is loosened until the clamping screw is again screwed tight. For example, the clamping part is embodied as a clip, which can be snapped onto a clip accept of an assembly plate (=assembly rack) of the furniture hinge. An assembly plate and a clip embodied in this manner are described, for example, in DE 299 02 768 U1.
EP 1 028 213 B1 shows another furniture hinge in which, for the depth adjustment, the hinge arm is adjustable in the direction of its longitudinal direction in reference to a retaining part. For the lateral adjustment (support adjustment), the angular position of the hinge arm in reference to a first intermediate plate is adjustable via an adjustment screw. The first intermediate plate is guided on the second intermediate plate, displaceable in the longitudinal direction for depth adjustment and can be fixed in reference to said second intermediate plate via a fastening screw, which penetrates an oblong hole in the first intermediate plate and can be screwed into a threaded bore of the second intermediate plate.
Additional furniture hinges, in which for the depth adjustment two parts of the carcass hinge part can be displaced in reference to each other in the longitudinal direction of the hinge arm and can be fixed via clamping screws, are known from DE 203 06 716 U1, DE 20 2004 013 401 U1, and EP 1 236 853 A1. In the furniture hinges of DE 203 06 716 U1 and EP 1 236 853 A2 an additional vertical adjustment occurs via an eccentric or a curved disk. Further, in the furniture hinge according to DE 20 2004 013 401 U1 a lateral adjustment (support adjustment) occurs via an adjustment screw, by which two parts of the assembly plate can be pivoted in reference to each other.
An assembly plate of a furniture hinge is further known from DE 201 20 238 U1, which is provided with first and second eccentrics, by which a clip accepting part can be adjusted in reference to a screw plate in directions that are perpendicular in reference to each other, in order to perform a depth adjustment and a vertical adjustment. A clip part connected to the hinge arm of the carcass hinge part can be snapped onto the clip accepting part. The screw of the eccentric for the depth adjustment is arranged between two lateral bars of the clip part and its rotational axis is aligned perpendicular in reference to the contact plane of the carcass hinge part at the furniture carcass. For the adjustment via an appropriate screw driver corresponding openings must be provided in the clip part and in the hinge arm and the space between these openings and the eccentric must be kept clear to allow access to the eccentric. This further narrows the already small space for installation in the carcass hinge part. Sufficient space in the carcass hinge part would be beneficial, in order to implement, for example, dampening cylinders or spring mechanisms in the carcass hinge part.
EP 1 288 416 shows a generic furniture hinge with an eccentric for the depth adjustment.
The invention provides a simply designed adjustable hinge of the type mentioned at the outset, in which in the carcass hinge part respective space can be kept clear for other built in parts.
According to the invention, the pivot axis of the eccentric is positioned parallel in reference to the pivot axis of at least one articulated lever.
The invention allows a simple depth adjustment, with space being kept clear in the carcass hinge part for other built in parts.
In a preferred embodiment of the invention, another eccentric is provided for the lateral adjustment (=support adjustment) of the door leaf in reference to the furniture carcass, by which the hinge part is adjustable in reference to the retaining part, with the axis of rotation of this additional eccentric also being positioned parallel in reference to the pivotal axes of at least one articulated lever. By this additional eccentric the hinge arm can be pivoted around a pivot axis in reference to the retaining part of the carcass hinge part, with the pivot axis being aligned parallel in reference to the pivot axis of the other eccentric, thus parallel to the pivot axes of at least one articulated lever. This way even a simple lateral adjustment is possible, with in turn space for other built in parts being kept clear in the carcass hinge part.
Advantageously, the space kept clear in the carcass hinge part can extend, from the end facing the door leaf hinge part, over a major part of the longitudinal extension of the carcass hinge part.
Preferably, the hinge arm is guided in a displaceable manner in reference to the retaining part by at least one pin, which engages an oblong hole extending essentially in the direction of the longitudinal direction of the hinge arm. At least one pin can be mounted to the retaining part or to the hinge arm and the oblong hole can be arranged at the respective other one of these two parts.
In the following, additional advantages and details of the invention are explained using the attached drawing.
In the drawings:
A first exemplary embodiment of the invention is shown in
The door leaf hinge part 4 can be embodied in form of a conventional hinge cup shown, for example, protruding in a recess in the door leaf 3 and provided with laterally protruding fastening flanges 12, 13, which are provided with threaded holes for screwing the door leaf hinge part 4 to the door leaf 3.
The furniture hinge can be embodied in a conventional manner closing automatically (over a last section of its closing motion.) using a spring arrangement. A dampening arrangement, not shown in the figures, may be provided to dampen the closing motion.
In the exemplary embodiment according to
The first eccentric 14, acting between the hinge arm 11 and the retaining part 16, serves for the depth adjustment of the door leaf 3 in reference to the furniture carcass 1. For this purpose, the hinge arm 11 is adjusted in the direction of its longitudinal extension in reference to the retaining part 16. Here, the door leaf 3 is essentially adjusted perpendicularly in reference to the plane 22 of the opening of the furniture carcass 1 (cf.
The pivot axis 23 of the first eccentric 14 is positioned parallel in reference to the pivot axes 7-10 of the articulated lever 5, 6.
The first eccentric 14 for the depth adjustment cooperates with at least one oblong hole 24, 25 in the retaining part 16 and at least one circular hole 26, 27 in the hinge arm 11. It is also possible to provide the at least one oblong hole 24, 25 in the hinge arm 11 and the at least one round hole 26, 27 in the retaining part 16. The at least one oblong hole 24, 25 extends in the longitudinal direction essentially aligned perpendicular in reference to the contact plane 20 of the carcass hinge part 2 and/or the longitudinal extension of the hinge arm 11.
“Essentially perpendicular” means here that the deviation from the right angle is preferably no greater than ±20°.
The longitudinal extension of the at least one oblong hole 24, 25 is also perpendicular in reference to the pivot axes 7-10 of the articulated levers 5, 6.
In the exemplary embodiment shown, the retaining part 16 is provided with two lateral bars 28, 29 spaced apart from each other and extending in the direction of the pivot axes 7-10 of the articulated lever 5. In each of the lateral bars 28, 29, the oblong hole 24, 25 is penetrated by a first eccentric 14. The lateral bars 28, 29 are connected to each other by a connection bar 30 at their edge spaced apart from the contact plane 20. Said bar is penetrated by a slot 31, by which the first eccentric 14 can be inserted into the oblong holes 24, 25 of the lateral bars 28, 29. The slot 31 is therefore located at the position of the connection bar 30 at which the oblong holes 24, 25 are open towards the edge of the lateral bars 28, 29 distanced from the contact plane 20.
The hinge arm 11 is embodied U-shaped and has lateral bars 38, 39 at both sides of the lateral bars 28, 29 of the retaining part 16, which are connected to each other by a connecting bar 40. Each of the lateral bars 38, 39 of the hinge arm 11 has a base hole 26, 27.
The first eccentric 14 has eccentric heads 47, 48, which are connected to each other by an eccentric shaft 49. The eccentric heads 47, 48 are located in the round holes 26, 27 and the eccentric shaft 49 penetrates the oblong holes 24, 25.
In an alternate arrangement, the round holes in the lateral bars 28, 29 are penetrated by the eccentric shaft 49 and the eccentric heads 47, 48 are arranged in the oblong holes in the lateral bars 38, 39.
The second eccentric 15 serves to the lateral adjustment (=side adjustment or support adjustment) of the door leaf 3 in reference to the furniture carcass 1. In this lateral adjustment the end of the carcass hinge part 2 facing the door leaf hinge part 4 is adjusted in a direction essentially perpendicular in reference to the contact plane 20. “Essentially perpendicular” means here that the adjustment direction preferably deviates no more than ±20° from the perpendicular of the contact plane 20. The door leaf 3 is here essentially parallel in reference to the plane 22 of the opening of the furniture carcass 1 and displaced perpendicular in reference to the pivot axes 7-10 of the articulated levers 5, 6 (cf.
For a lateral adjustment, the hinge arm 11 is swiveled around a pivot axis 32, which is parallel in reference to the pivot axes 7-10 of the articulated lever 5, 6, in reference to the retaining part 16 via a second eccentric 15. The pivot axis 33 of the second eccentric 15 is aligned parallel in reference to the pivot axes 7-10 of the articulated levers 5, 6, and thus parallel in reference to the pivot axes 23 of the first eccentric 14.
The pivot axis 33 of the second eccentric 15 is arranged parallel to the pivot axis 32, around which the hinge arm 11 can be pivoted in reference to the retaining part 16 via the second eccentric 15.
The second eccentric 15 cooperates with at least one oblong hole 34, 35, which is arranged in the retaining part 16, and with at least one round hole 36, 37, which is arranged in the hinge arm 11. At least one oblong hole 34, 35 can also be arranged in the hinge arm 11 and at least one round hole 36, 37 in the retaining part 16. The longitudinal extension of at least one oblong hole 34, 35 is positioned essentially parallel in reference to the longitudinal extension of the hinge arm 11 and/or essentially parallel in reference to the support plane 20 of the carcass hinge part 2 and perpendicular in reference to the pivot axes 7-10 of the articulated levers 5, 6. “Essentially parallel” here means that the deviation from the parallel is preferably no greater than ±20°.
In the exemplary embodiment shown, two of the oblong holes 34, 35 are provided in the lateral bars 28, 29 of the retaining part 16. They preferably open at the edge of the lateral bar 28, 29, respectively facing the door leaf hinge part 4, so that the second eccentric 15 can be inserted from this edge into the oblong holes 34, 35. Furthermore, two of the round holes 36, 37 are provided in the lateral bars 38, 39 of the hinge arm 11. The second eccentric 15 has two eccentric heads 41, 42 located in the round holes 36, 37, which are connected via an eccentric shaft 43 penetrating the oblong holes 34, 35.
In case of an arrangement of the round holes in the lateral bars 28, 29 they would be penetrated by the eccentric shaft 43 and the eccentric heads 41, 42 would be arranged in the oblong holes in the lateral bars 38, 39.
The pivot axis 32 for the lateral adjustment is farther distanced from the end of the carcass hinge part 2 facing the door leaf than the second eccentric 15 and is located in the proximity of the first eccentric 14.
The first eccentric 14 is spaced farther from the end of the carcass hinge part 2 facing the door leaf than the second eccentric 15.
In reference to the retaining part 16, the hinge arm 11 is guided in a displaceable manner in a direction in an essentially parallel in reference to the contact plane 20 and perpendicular in reference to the pivot axes 7-10 of the articulated levers 5, 6 and/or essentially parallel to its longitudinal direction. “Essentially parallel” means that the deviation from the parallel is preferably no greater than ±20°. For this displaceable guidance, preferably at least one pin 44 is provided at the retaining part 16 which extends into at least one oblong hole 45, 46 embodied at the hinge arm 11, with the oblong hole extending in the displacement direction, i.e. essentially in the direction of the longitudinal extension of the hinge arm 11. At least one pin 44 could be mounted at the hinge arm 11 and extend into at least one oblong hole arranged at the retaining part 16 and extending in the displacement direction. In the exemplary embodiment shown, a pin 44 is provided which penetrates the holes in the two lateral bars 28, 29 of the retaining part 16 and is held thereby and protrudes in the oblong holes 45, 46 in the two lateral bars 38, 39 of the hinge arm 11. For example, at both lateral bars 28, 29 of the retaining part 16 separate protruding pins may also be provided.
At least one pin 44 forms the pivot axis 32, around which the hinge arm 11 is pivotal in reference to the retaining part 16 for a lateral adjustment.
The displaceable guidance of the hinge arm 11 in reference to the retaining part 16 is further caused by the second eccentric 15 penetrating at least one oblong hole 34, 35 aligned in the displacement direction.
The adjusted position of the hinge arm 11 in reference to the retaining part 16 is upheld by friction between these two parts.
For vertically adjusting the first eccentric 14 it is pivoted around its pivot axis 23, by which the hinge arm 11 is displaced in its longitudinal direction in reference to the retaining part 16. For the lateral adjustment the second eccentric 15 is pivoted around its pivot axis 33, causing the hinge arm 11 to be pivoted around the pivot axis 32 in reference to the retaining part 16.
In the area between the eccentric shaft 49, 43 and the contact plane 20, a continuous hollow space remains inside the retaining part 16, extending in the longitudinal direction of the hinge arm 11, extending from the end of the retaining part 16 facing the door leaf through the interior space of the hinge arm 11 to the articulated lever mechanisms. In this free space other built in elements can be implemented, for example a dampening cylinder, a touch-latch, or another spring device.
