Definitions
- the present invention relates to a multi-joint hinge, multi-joint hinge, in particular for a refrigerator, with a mounting element that can be fixed on a body and a hinge part that can be fixed on a door and which can be pivoted on the mounting element between a closed position and a maximum opening position, the hinge part being prestressed in the closing direction in a tightening range by a spring and at least one linear damper having a damper housing and a piston rod which can be displaced relative to the damper housing and which causes a closing movement of the hinge part before the closed position is reached slow down.
- WO 2008/119647 discloses a multi-joint hinge in which a hinge part is held pivotably on a fastening element, with a spring being provided within the lever of the joint mechanism for drawing a door that can be fixed to the hinge part into the closed position.
- a linear damper is also provided, which comprises a damper housing and a displaceable piston rod.
- the linear damper is rotatably mounted here and thus requires additional installation space due to the pivoting movement.
- a slot is formed on one of the levers so that the linear damper can only be moved when the hinge part is arranged just before the closed position.
- WO 2018/104199 proposes providing a damper arrangement with two parallel linear dampers in a multi-joint hinge.
- the two linear dampers are fixed to the damper housing via an eyelet on one side and the piston rod is connected to an eyelet on the opposite side, so that compressive and tensile forces can be exerted on the linear damper.
- the linear damper is also rotatably mounted and thus requires additional installation space due to the pivoting movement.
- the manufacture and assembly of these dampers is comparatively complex, and the linear dampers are also very long in terms of their overall length and over the entire length Pivoting range of the hinge part coupled to the levers of the linkage mechanism. As a result, additional space is required.
- At least one linear damper which comprises a damper housing and a displaceable piston rod, is arranged with the damper housing in a rotationally fixed manner via a holding element within a lever and the holding element is fixed to a lever of the joint mechanism and the piston rod is Can be pushed into the damper housing via an actuating element, the actuating element being arranged on a further lever of the joint mechanism.
- the damper housing can be positioned with a predetermined orientation within the multi-joint hinge via the receptacle, in order to then generate damping forces during a closing movement of the hinge part.
- the lever can be U-shaped or L-shaped in cross section, so that the retaining element is accommodated in a groove-shaped or angular channel in the lever.
- the lever preferably has a U-shaped cross section and the damper housing of the at least one linear damper is arranged between the two legs of the lever.
- the actuating element preferably has an arcuate contour on which the piston rods can slide directly or indirectly with one end face.
- the actuating element is designed here as a pin, for example as a cylindrical pin, which is fixed between two walls of the further lever of the joint mechanism.
- At least one piston rod of the linear damper can move on the actuating element and is preferably perpendicular to the longitudinal direction of the Piston rods aligned. Two or more piston rods of the linear dampers can also move at the same time or in a staggered manner relative to one another on the actuating element. If the linear dampers are offset, a particularly gentle damping process can be achieved.
- the actuating element can be designed as a cylindrical pin or with a different cross-sectional shape.
- the actuating element on the further lever can act on the piston rods when the hinge part is pivoted in a damping area and can be moved freely in an area outside the damping area.
- a part of the pivoting range of the hinge part is designed as a freewheel in which no damping forces act. This is achieved in that the actuating element is arranged in the area of the freewheel at a distance from the piston rods and does not contact them. This freewheel is independent of any spring forces.
- the actuating element can be adjusted, in particular slidably, attached to the further lever and thus allow the area of the freewheel to be adjusted in relation to the damping forces.
- the holding element is fixed to a joint axis between the lever and the further lever.
- the holding element can also be attached to one of the levers of the hinge.
- the installation space within the multi-joint hinge can be optimally used for the linear damper.
- the holding element can have a stop which is supported on a wall of the lever.
- a stop element is preferably provided on each receptacle, which limits a movement of a damper housing when the piston rod is pushed in and supports it on the side opposite the piston rod.
- the stop element can be designed, for example, as a stop pin that is fixed to two walls of the lever and extends through the holding element. As a result, high forces when the piston rod is pushed in can also be absorbed by the stop element, which is fixed at opposite ends to the walls of the lever.
- the holding element can, for example, consist of molded bodies made of plastic or comprise such.
- the stop element can be designed as a metallic pin and is therefore designed to absorb higher forces.
- an adjustment mechanism can be integrated into the damper housing, with the help of which a linear adjustment of the damper housing or the piston rod and, as a result, an adjustment of the damping performance is made possible.
- the spring of the multi-joint hinge preferably acts on a guide lever or a slide which can be moved along a curved guide when the hinge part is pivoted.
- a tightening range of the spring can be defined via the curve guide, which preferably lies between the closed position of the hinge part and an opening angle of the hinge part of between 20° and 40°.
- the effective range of the linear damper ie the damping range, is preferably smaller than the tightening range of the spring in relation to the pivoting range of the hinge part, so that the door does not stop unintentionally in an opening range.
- the two linear dampers can, for example, be effective between a closed position of the hinge part and an open position of the hinge part between 10° and 25°, in particular 15° and 20°.
- the effective range can begin when damping forces are generated via the linear damper after overcoming a possible idle stroke.
- Each linear damper preferably has a spring element that biases the piston rod into a protruding position.
- the actuating element for compressing the linear damper can only apply pressure and compress it, while the piston rod of the linear damper is automatically moved into the extended position during an opening movement of the hinge part.
- the multi-joint hinge is preferably designed as a seven-joint hinge with four levers that can be pivoted relative to one another and form a total of seven joints.
- the multi-joint hinge can also be designed as a four-joint hinge.
- At least one lever of the joint mechanism is preferably designed as a sheet steel part bent into a U-shape and can absorb high weight loads.
- At least two linear dampers are provided, wherein the piston rods can be pushed together into the damper housing at least in a partial area between the closed position of the hinge part and an open position of the hinge part via the actuating element.
- the use of two dampers arranged in parallel on the multi-joint hinge also enables heavy door weights, for example refrigerator doors, to be braked.
- the actuating element on the further lever preferably acts on the at least one piston rod when the hinge part is pivoted in a damping area and can be moved freely in an area outside the damping area. The actuating element is thus arranged in the area of the freewheel at a distance from the at least one piston rod. As a result, the linear damper does not have to be attached to opposite sides.
- the actuating element includes an inlet guide for the at least one piston rod.
- the inlet guide can be designed like a funnel in order to effect lateral guidance towards the actuating element when the piston rod enters the inlet guide.
- the inlet guide for the at least one piston rod can allow a small amount of lateral play and accommodate the piston rod with play, preferably with a lateral play of less than 1 mm.
- the actuating element is preferably designed to be adjustable relative to the linear damper, so that a contact point between the at least one piston rod and the actuating element can be adjusted as a function of the angular position of the hinge part. This allows the damping range to be adjusted.
- the multi-joint hinge is preferably used in a refrigerator with an appliance body and a door pivotably mounted on the appliance body.

- the fourth lever 7 and the insertion element 9 thus form a unit that can be moved together, with the insertion element 9 optionally also being able to be formed integrally with the fourth lever 7 .
- An axis A14 is formed on the insertion element 9, into which an actuating element 14 in the form of a pin is inserted. In the mounted position, the actuating element 14 can act on the front ends of piston rods 32 , which can then be pushed into the damper housing 31 .
- the multi-joint hinge 1 comprises two linear dampers 30, each with a damper housing 31 and a piston rod 32. It is also possible for only one linear damper 30 to be provided.

- the linear dampers 30 are fixed to a holding element 33, which has two adjacent receptacles 35, into each of which a part of a damper housing 31 is inserted. The insertion depth of the damper housing 31 is limited by a stop 34 .
- the stop 34 is designed as a stop pin and is inserted into an opening 37 of the holding element 33 .
- the stop 34 is at opposite ends on the first Lever 4 is held, for which purpose openings 36 for inserting one end of the stop 34 are formed on the first lever 4 .

- the hinge part 3 has an L-shaped cross section, with a mounting part 103 being fixed to the hinge part 3 so that the sixth axis A6 and the seventh axis A7 can run between a wall of the hinge part 3 and the mounting part 103.
- the mounting part 103 forms a spacer so that the cover 8 can pivot.
- the levers 6 and 7 are arranged inside the egg-shaped door bearing made up of the hinge part 3 and the assembly part 103 .
- the multi-joint hinge 1 also includes covers 8, which cover gaps between the third lever 6 and the fourth lever 7 in an open position, and thereby form a protection against access.
- the covers 8 can be held in an articulated manner on the stop 34 or on another axis and have a slot guide which interacts with a guide pin fixed on the hinge part 3 .
- the multi-joint hinge 1 is shown in different positions. In the folded closed position, the levers 4, 5, 6 and 7 of the link mechanism are nested and the multi-joint hinge 1 is box-shaped.
- FIG. 3D shows the maximum opening position of the hinge part 3, which is, for example, in a range between 100° and 150° away from the closed position.
- the opening angle can be determined on the basis of two surfaces of the mounting element 2 and the hinge part 3 which are parallel in the closed position.
- the multi-joint hinge 1 is shown in a sectional view.
- Each linear damper 30 has a damper housing 31 inserted into the holding element 33 , with a front end of the damper housing 31 being supported on the stop 34 which is held between two walls of the first lever 4 .
- the stop 34 designed as a stop pin can be made of metal and absorb high compressive forces.
- the piston rod 32 rests with an end face on the actuating element 14, which is designed as a pin, in particular as a cylindrical pin.
- the actuating element 14 can also be made of metal in order to be able to transmit high compressive forces.
- the spring 10 is connected in an articulated manner to the insert element 9 between the first guide element 11 at an axis A11.
- the guide element 11 projects into the spring 10 with a pin, and the second guide element 12 also has a pin for guiding the spring 10 .
- the pins ensure centering within the lever 7.
- the insert element 9 serves to center the guide element 11 within the lever 7, which can preferably be moved without grinding.
- the second guide element 12 is connected in an articulated manner to the guide lever 13, which is held in an articulated manner on the insertion element 9 centered around the axis A13.
- the guide lever 13 is used to move a guide roller 15 which rolls along a curved guide 18 .
- the curved guide 18 is formed on the guide element 16 which is held on the hinge part 3 in a rotationally fixed manner.
- two linear dampers are arranged next to one another on the holding element 33, both of which are supported by a single stop 34 and the piston rods 32 of which can both be moved by an actuating element 14.
- the longitudinal axes of the actuating element 14 and the stop 34 extend perpendicular to the longitudinal axes of the linear dampers.
- FIG 5A the multi-bar hinge is shown in a maximum open position. It can be seen that the spring 10 is arranged in a compressed, compressed position and the guide roller 15 has been moved along the cam guide 18 .
- the linear damper 30 is arranged on the holding element 33, and the piston rod 32 of each linear damper is arranged in a free-standing manner without contact with any other component.
- the multiple steering hinge is in a freewheel position.
- the linear damper 30 is not effective in the freewheeling position.
- the guide roller 15 moves along the cam guide 18.
- the spring remains up to an angle of about 30° before the closed position, for example between 20° and 40° before the closed position 10 in the compressed position, since the first guide element 11 and the second guide element 12 do not move or move only slightly relative to one another.
- the hinge part 3 reaches the angular position in which the tightening range begins, the guide roller 15 is moved on the cam guide 18 in such a way that the guide lever 13 pivots so that the second guide element 12 moves away from the first guide element 11 .
- the spring 10 compressed under pressure can relax and thus supports the closing process.
- an end face of the piston rod 32 is still at a distance from the actuating element 14, since the linear damper 30 only becomes effective later during a closing movement.
- FIG. 5C shows the position of the hinge part 3 in which the actuating element 14 begins to push the piston rod 32 into the damper housing 31.
- the damper housing 31 is supported by the stop 34 so that a closing movement of the hinge part 3 can be braked.
- the spring 10 ensures that the hinge part 3 is prestressed in the closing direction.
- FIG. 5D shows the closed position in which the spring 10 has been relaxed by moving the guide roller 15 along the cam guide 18. At the same time, the piston rod 32 was pressed into the damper housing 31, as a result of which the movement of the hinge part 3 was braked.
- the linear damper 30 is shown in an enlarged view in FIGS. 6A and 6B.
- the linear damper 30 is in a freewheeling position and does not touch the actuating element 14.
- the actuating element 14 has a curved surface. This curved surface is surrounded by an inlet guide 38 .
- the inlet guide 38 is designed like a funnel.
- the inlet guide 38 serves as a guide for the piston rod 32.
- FIG. 6B shows the moment at which the piston rod 32 strikes the actuating element 14 directly. It can be seen that the inlet Guide 38 of the piston rod 32 allows only minimal lateral play, with unwanted transverse forces that can act on the piston rod 32 being prevented.
- the damper 30 thus executes a partial orbit around the actuating element 14 .
- the inlet guide 38 is formed, among other things, in such a way that the piston rod 32 is not pushed laterally away from the inlet guide 38 when partially encircling the actuating element 14 .
- the two linear dampers 30 are mounted between the first lever 4 and the fourth lever 7 . It is of course also possible to provide the linear damper between two other levers 4, 5, 6 and 7 or on the mounting element 2 designed as a lever or on the hinge part 3.
- the spring 10 with the guide lever 13 can also be mounted at a different position of the multi-joint hinge than between the fourth lever 7 and the hinge part 3.
- the linear damper 30 and the actuating element 14 are not adjustable. However, it is also possible for the linear dampers 30 to be arranged on an adjustable carriage on the holding element 33 . An eccentric or a worm wheel can be provided as adjustment means. The linear damper 30 can be adjusted from outside the lever 4 .
- the actuating element 14 can be mounted in an adjustable manner.
- a threaded device can be provided on the actuating element 14 so that the actuating element can be shifted in depth.
- the actuating element is designed as a pin 14, the bolt can be guided laterally in a guide on the lever 7. It is essential here that the actuating element 14 can be adjusted relative to the linear damper 30 so that a contact point between the at least one piston rod 32 and the actuating element 14 can be adjusted as a function of the angular position of the hinge part 3 .
