Abstract
Description
[0001] hinge
[0002] The present invention relates to a hinge for furniture with a stationary side part that can be fixed in a pocket of a side wall and a hinge part that can be fixed to a door and is rotatably held on the side part about a joint axis, wherein a movable drive element is provided between the hinge part and the side part.
[0003] DE 195 06 714 A1 discloses a furniture hinge that can be fixed to the inside of a side panel to rotatably mount a door leaf stop element with a countersunk insert cup about a pivot axis. To limit the maximum opening position, an overtravel stop with a pull element designed as a metal wire bracket is provided. This overtravel stop protrudes into the interior of the furniture and poses a risk of injury.
[0004] EP 4 010 553 A1 discloses a hinge in which a side part of the hinge can be inserted into a pocket in the side panel of a piece of furniture. A hinge part is rotatably mounted on a section of the side part projecting from the side panel about a pivot axis. During rotation, the hinge part acts on a movable drive element, which can be moved against two dampers to decelerate a closing movement. While such a hinge can be compactly arranged in a pocket in the side panel of a piece of furniture, the maximum opening angle of the hinge part is predetermined by the movement mechanism. Depending on the installation situation, the problem may arise that a door held by the hinge part can be opened too little or too far.
[0005] It is therefore an object of the present invention to create a hinge that can be flexibly adapted to different installation situations with regard to the opening angle.
[0006] This problem is solved by a hinge with the features of claim 1. The hinge according to the invention for furniture comprises a stationary side part that can be fixed in a pocket of a side panel and a hinge part that can be fixed to a door and is rotatably mounted on the side part about a pivot axis. A movable drive element is provided between the hinge part and the side part, wherein adjustable means for limiting the maximum opening angle of the hinge part are arranged on the drive element. This allows for flexible adaptation to the installation situation, as the means for limiting the maximum opening angle directly or indirectly restrict the movement of the hinge part. The hinge is designed as a single-joint hinge, in which the hinge part is rotatably mounted about a single pivot axis relative to the side part.To limit the maximum opening angle, the movable drive element is used, which is moved relative to the side part during a rotational movement of the hinge part, enabling a compact design.
[0007] The pivot axis of the hinge is preferably vertically aligned in the installation position, but can also be inclined to it or horizontally aligned.
[0008] Preferably, the maximum opening angle is continuously adjustable by means of adjustable means for limiting the maximum opening angle. This allows the maximum opening position to be set optionally. The angle by which the opening angle can be changed in the open position is preferably in a range of 10° to 30°. This allows the maximum opening angle to be set, for example, in a range between 85° and 115°, preferably between 90° and 105°. The adjustable means for limiting the maximum opening angle can comprise an eccentric, a worm gear, and / or a thread.
[0009] In a preferred embodiment, the drive element is slidably mounted on the side panel. For this purpose, appropriate guides can be provided on the drive element and / or the side panel. The drive element can be moved via a drive lever, which is pivotally connected to the hinge part and also pivotally connected to the drive element, spaced apart from the pivot axis. This causes the drive element to be moved relative to the side panel during an opening and closing movement.
[0010] A linear guide for a guide element is preferably formed on the side panel, and a stop is provided at one end of the linear guide to limit the movement of the guide element and thus of the hinge part. This allows for a compact design that limits the maximum opening angle. The linear guide can, for example, be designed as an elongated hole or slot in the drive element, into which a guide element, such as a rivet or a locking element, engages. To adjust the maximum opening angle, the position of the guide element relative to the drive element can be changed, for example, by means of an adjusting element rotatably mounted on the drive element, such as an eccentric. The adjusting element can have a tool engagement or, alternatively, be operable without tools via a handle.The adjustment element can provide haptic and / or acoustic feedback when rotated or moved, for example via detents, so that the respective adjustment position is easier to determine. Access to the adjustment element is preferably when the door is open.
[0011] In a further embodiment, the hinge can comprise a force storage device by means of which the hinge part is pre-tensioned towards a closed position in a tightening area, and a damping element by means of which the hinge part can be decelerated before reaching the closed position. The force storage device and the damping element can be connected to a driver that is movable along a guide track and can be coupled to the drive element at least over part of its path. For this purpose, the guide track, for example on a guide housing, can have an angled end section so that a connection between the driver and the drive element can be engaged or disengaged when the driver is pivoted.
[0012] The side panel is preferably adjustable within a box-shaped housing, wherein the side panel is adjustable relative to the housing, preferably in height, in the installed position. Adjustment means, such as a worm gear or other adjustment devices, may be provided for this purpose. The box-shaped housing may be fixed to a side wall of a furniture carcass by means of protruding mounting tabs.
[0013] A piece of furniture preferably comprises a furniture body with a side wall in which a pocket in the form of a recess is provided, into which at least the side panel is inserted and fixed, in particular via the box-shaped housing. This means that the side panel does not require any usable volume within the furniture body. Figure 1 shows a partial perspective view of a piece of furniture with a hinge according to the invention.

[0023] A piece of furniture 100 comprises a furniture body with a side wall 101, to which at least one hinge 1 according to the invention is fixed and to which a door 102 is pivotably held. Preferably, several hinges 1 are mounted one above the other on the side wall 101.
[0024] In Figure 2A, the door 102 is arranged in a closed position on the side wall 101. The hinge 1 is arranged essentially flush with an end face of a frame or a panel-shaped door 102.
[0025] In Figure 2B, the door 102 is pivoted by the hinge 1 into a maximum opening position, for example, by an opening angle between 90° and 120°. The hinge part 3 is held in a hinge cup 5, and the hinge cup 5 is also arranged essentially flush with the surface of the door 102 on an inner side. A side part 2 of the hinge 1 is fixed in the side wall 101, projecting from an end face of the side wall 101 with two arms 20. A pivot axis for the rotatable mounting of the hinge part 3 is formed on the arms 20. A drive lever 13 is also pivotally mounted on the hinge part 3, which is pivotally connected to a drive element 6 on the side part 2 and by means of which a closing movement of the door 102 can be at least partially controlled.
[0026] Figure 3A shows the hinge 1 in a closed position. The side part 2 comprises a housing 4 with two housing shells, which is essentially box-shaped, with a mounting tab 43 projecting from both a top and a bottom surface, each with an opening into which fastening means can be inserted. The housing 4 with the side part 2 can be fixed to an end face of the side wall 101 by means of the fastening means, the housing 4 being arranged in a pocket within the side wall 101.
[0027] The hinge part 3 is adjustable within a hinge cup 5, which has a mounting tab 51 with an opening on each of its opposite sides, so that the hinge cup 5 can also be substantially fixed to a receptacle or pocket on the door 102. In a closed position, a substantially flat side of the hinge cup 5, in which the hinge part 3 is arranged, faces a flat side of the housing 4, on which the mounting tabs 43 are formed. The hinge cup 5 is wider than the housing 4.
[0028] In the open position shown in Figure 3B, the hinge part 3 was pivoted relative to the side part 2 in the housing 4, causing the drive lever 13 to move the drive element 6 relative to the housing 4.
[0029] Figure 4 shows an exploded view of the hinge 1 according to the invention. The housing 4 comprises a first housing shell 40 and a second housing shell 41, which, in the assembled position, have a substantially vertical dividing plane. Several guide pins 42 are formed on the housing shell 40, which engage in elongated holes 23 on the side part 2. The elongated holes 23 are aligned parallel to a pivot axis of the hinge 1 and allow height adjustment of the side part 2 relative to the housing 4. A worm gear 16 is provided for height adjustment. The worm gear 16 is rotatably mounted on the side part 2 via an axis that engages in an opening 29. The worm gear 16 is driven by a rotating part 15, which engages in a profile on the circumference of the worm gear 16, for example, with teeth, so that turning the rotating part 15 rotates the worm gear 16. The rotating part 15 is rotatably mounted on a bracket 28 of the side part 2.The worm 16 rests with a rib on a guide contour on the housing shell 41, so that by rotating the worm 16 the side part 2 can be moved relative to the housing 4 along the elongated holes 23.
[0030] The drive lever 13 is pivotally connected to the hinge part 3 and has a bearing opening 17 for a pivot axis for this purpose. On the opposite side, there is a bearing opening 14 into which an axis can be inserted, which engages a bearing element 63 on the drive element 6 to pivotally mount the drive lever 13 to the drive element 6. The drive element 6 is slidably guided on the side part 2, for which a groove 26 is provided in the side part 2 in which the drive element 6 is inserted. An adjusting element 62 is mounted on the drive element 6 in a receptacle 61. In this case, the adjusting element 62 is an eccentric. The adjusting element 62 engages in a first opening 65 on an intermediate plate 64. A second opening 66 of the intermediate plate 64 is connected via a guide element, e.g., a rivet, to a linear guide, e.g., a slot 27, in a groove bottom of the groove 26.One end of the linear guide acts as a stop for the guide element. By actuating the adjusting element 62, the intermediate plate 64 can be adjusted relative to the drive element 6. This allows the maximum opening position of the hinge to be adjusted.
[0031] In this embodiment, the adjusting element 62 has a tool engagement, for example for a screwdriver. However, it is also conceivable to provide for tool-free adjustment of the adjusting element 62.
[0032] Access to the adjustment element 62 is gained from the inside in a (partially) open position, approximately perpendicular to the side wall 101. This allows for good accessibility of the adjustment element 62 and adjustment of the maximum opening angle without requiring any further openings / drilling in the side wall 101. Advantageously, acoustic or haptic feedback can be provided when the adjustment element 62 is actuated.
[0033] The drive element 6 further comprises a hook 60 which can be coupled to a pin 81 of a driver 8. The driver 8 has guide pins 80 on opposite sides and is guided on a guide housing 7.
[0034] The guide housing 7 is fixed to the side part 2 by means of several webs 74 formed on the guide housing 7, each of which has cuboid projections 75. The cuboid projections 75 engage in recesses 24 and slots 25 on the side part 2. The side part 2 has two spaced-apart webs 22 that extend longitudinally in the direction of movement of the drive element 6, and the guide housing 7 is arranged between the webs 22. Other fastening mechanisms may also be provided for fixing the guide housing 7 to the side part 2.
[0035] The guide housing 7 comprises a first receptacle 71 into which a power storage element 10 is inserted. Furthermore, a second receptacle 70 is formed on the guide housing 7 into which a damping element 9, in particular a linear damper, is inserted. A holder 72 is provided on the first receptacle 71, to which one end 11 of the power storage element 10 can be fixed. An end 12 of the power storage element 10 opposite end 11 is fixed to the driver 8. The driver 8 has two guide pins 80 on opposite sides, each of which engages in a guide track 76 on the guide housing 7. The guide track 76 is designed as a slot or groove and comprises a linear section and an angled end section 77.
[0036] The hinge part 3 has a receptacle 31 for an eccentric 32, a cylindrical channel 33 for a rivet 34, and a receptacle 35 for a screw 36. The hinge part 3 can be adjusted relative to the hinge cup 5 in two spatial directions via the eccentric 32 and the screw 36. The hinge part 3 is located adjacent to an intermediate plate 37 and can be inserted into a cup insert 53, which can be inserted into the hinge cup 5 via a clip connection. The cup insert 53 surrounds the hinge part 3 in a U-shape and includes a receptacle 54 on one leg, in which a clip holder 55 is rotatably mounted on an axis 56. The clip holder 55 is pre-tensioned by a leaf spring 57 and can be adjusted within the hinge cup 5.
[0037] Bearing receptacles 21 are formed on the two arms 20 of the side part 2, into which a pin can be inserted to form a pivot axis. The pin then extends through the two arms 20, between which a bearing section of the hinge part 3 is arranged.
[0038] In Figure 5, the hinge 1 is in an open position. The drive lever 13 has partially pulled the drive element 6 out of the housing 4, and the hook 60 of the drive element 6 is disengaged from the driver 8. The driver 8 is located with two guide pins 80 on the angled end section 77 of the guide track 76, and the energy storage device 10 is in a tensioned position. If the hinge part 3 is now pivoted from the open position in the closing direction, the drive lever 13 pushes the drive element 6 towards the guide housing 7.
[0039] In Figure 6, the hinge part 3 is in its open position, in which the drive element 6 is coupled to the driver 8. The hook 60 of the drive element 6 presses against a contact surface of the driver 8, causing it to move out of its pivoted position. The two guide pins 80 facing the drive element then engage not on the angled end section 77, but in the linear section of the guide track 76. This unlocks the driver 8 from its locked park position, and the energy storage device 10 can now move the driver 8 along the guide housing 7. The energy storage device 10 is designed as a tension spring and thus pulls the driver 8, and consequently the drive element 6, into the housing 4.
[0040] In Figure 7, the drive element 6 was moved into the closed position by the driver 8 and the energy storage device 10. The hinge part 3 was pivoted into the closed position, also shown in Figure 3A, via the drive element 6 and the drive lever 13. By moving the drive element 6 and the driver 8, the damping element 9 was moved into the compressed position and could thus decelerate the closing movement after coupling with the driver 8. When the hinge part 3 is pivoted in the opening direction, the driver 8 is moved again via the drive element 6 to the angled end section and parked there, so that the drive element 6 is again decoupled from the driver 8.
[0041] Figures 8A and 8B show the hinge 1 in its maximum opening position. In this position, the drive lever 13 has pulled the drive element 6 out of the housing 4. The intermediate plate 64 has been moved along the side panel 2 via the adjusting element 62 on the drive element 6. The intermediate plate 64 has an opening 65 for a guide element, in particular a rivet, which moves along the elongated hole 27 on the side panel 2. When the maximum opening position is reached, the guide element, which is slidably mounted on the side panel 2, has reached the end of the elongated hole 27 and thus rests against an end stop. This limits the maximum opening angle of the hinge part 3, which can no longer be moved further in the opening direction.During a closing movement, the hinge part 3 rotates around the joint axis, and the drive lever 13 moves the drive element 6 back into the housing 4, thereby moving the adjusting element 62 with the intermediate plate 64 and moving the guide element along the slot 27 at the opening 65.
[0042] To adjust the maximum opening angle, the adjusting element 62, in the form of an eccentric, can be rotated so that the distance between an axis of rotation of the eccentric and the opening 65 is changed in a direction parallel to the sliding direction of the drive element 6. This change reduces or increases the maximum opening angle of the hinge part 3.
[0043] Figure 9 shows the drive element 6 on the side panel 2 in a maximum opening position. It can be seen that the guide element on the intermediate plate 64 has been moved to the end of the elongated hole 27, and the drive element 6 is movable in a groove-shaped receptacle 26 of the side panel 2 between the two arms 20. The drive element 6 is moved via the drive lever 13, which is pivotally mounted on a bearing opening 14 of the drive element 6 and pivotally connected to the hinge part 3 on the opposite side. To adjust the maximum opening angle, the adjusting element 62, in the form of an eccentric, is rotated within the receptacle 61 on the drive element 6. This moves the intermediate plate 64 either in the direction of movement of the drive element 6 or in the opposite direction, thus shortening or lengthening the travel path of the drive element 6.
[0044] In the illustrated embodiment, the maximum opening angle can be changed via the adjusting element 62 and the intermediate plate 64. It is also possible to use a threaded element, a worm gear, or another adjusting element instead of an eccentric as the adjusting element 62. Furthermore, the linear guide for a guide element on the side part 2 is formed by the elongated hole 27, which can also be replaced by a linear guide with a guide rib or a groove. Other guide means can also be provided on the side part 2; for example, the drive element 6 can also be moved against an adjustable stop to change the maximum opening angle.
