Definitions

  • the present invention relates to a hinge for a piece of furniture or a household appliance, according to the preamble of claim 1.
  • the DE 44 18 238 A1 discloses a multi-joint hinge that has a lever mechanism between two hinge elements that creates changing openings when the hinge parts are pivoted, which are covered by a cover in the manner of a protective cap. This can prevent anyone from reaching into the openings.
  • Such an elastic protective cap can deform when the hinge is pivoted, but this leads to additional forces when the material is stretched.
  • the protective cap also contains hollow spaces and is therefore comparatively large.
  • a universal joint hinge which comprises on an outer side a cover element with a plurality of spaced-apart cover strips which are movable relative to one another.
  • the hinge according to the invention comprises a cover element for the lever mechanism between the two hinge parts, wherein several cover plates are formed integrally with the cover element, and the cover plates arranged on one side of the lever mechanism can be pivoted relative to one another in a partially overlapping position when the hinge is pivoted.
  • the cover plates are thus movable relative to one another and can be adapted to the shape of the lever mechanism, wherein the cover plates can overlap when the hinge part is pivoted, so that the necessary installation space for the cover element is reduced.
  • the cover plates arranged on one side are connected to one another via a flexible web or a film hinge or another connection with a joint axis.
  • a film hinge forms a joint axis
  • the flexible web can have a length of, for example, more than 10 mm, in particular between 20 mm and 50 mm, in order to guide two cover plates movably against one another by means of a bending movement.
  • the cover plates are pivoted about an axis that is aligned parallel to the joint axes of the lever mechanism.
  • cover plates that can be pivoted relative to one another are provided on opposite sides of the lever mechanism and are formed integrally with the cover element.
  • three cover plates are provided on opposite sides of the lever mechanism, whereby the number of cover plates can also be varied depending on the design of the lever mechanism.
  • the cover element preferably has a U-shaped and strip-shaped section in cross section, the legs of which are formed by the cover plates, which are held together by a connecting web.
  • the connecting web can be formed beyond the area with the cover plates and then form a bendable web, at the end section of which two further cover plates are provided.
  • the cover element can be plugged or snapped onto the lever mechanism.
  • the cover element can have a tab with a recess for fixing to a lever of the lever mechanism.
  • the cover element can also have a curved mounting tab that is plugged around a lever of the lever mechanism for fixing.
  • the cover element is preferably made from a punched and folded plastic film, for example from a biaxially oriented polyester film. Other films can also be used, the thickness of the film preferably being between 0.05 mm and 0.5 mm. Alternatively, the cover element can be made from a thin metal sheet.
  • the first hinge part comprises a strip-shaped section with a U-shaped cross-section, wherein a part of the cover element, in particular the part with a connecting web,
  • the cover element with the cover plates does not protrude laterally beyond the hinge, but is arranged between the legs of the first hinge part.
  • the hinge part with the U-shaped section can have a web, from which two legs extend essentially at right angles.
  • the hinge according to the invention is preferably used in household appliances, such as a refrigerator. However, it can also be used for furniture or other purposes.
  • the hinge according to the invention can also have a closing and/or opening damper.
  • the damper can be located within the lever arms of the hinge.
  • FIGS 1A and 1B show a household appliance 1 or piece of furniture with a body 2 on which a door 3 is pivotably mounted via one or more hinges 4.
  • a first hinge part 5 is fixed to the body 2, while a second hinge part 6 is fixed to the door 3.
  • a lever mechanism between the two hinge parts 5 and 6 is largely concealed by a cover element 10 in order to prevent interference with the lever mechanism.
  • Figure 1B shows the Figure 1A designated area B in a detailed view.
  • the hinge 4 is shown in an open position.
  • the hinge 4 comprises a lever mechanism with levers 8, which are each hinged to at least two hinge axes 7, wherein the two hinge axes 7 are formed on the first hinge part 5, two hinge axes 7 on the second hinge part 6 and three further hinge axes 7 between the levers 8.
  • a seven-joint hinge is for example in the EN 10 2016 123 498 A1 or in the EP 2 129 852 B1 which is hereby incorporated by reference.
  • the EN 10 2016 123 498 A1 or in the EP2 129 852 B1 also describes a damping for such seven-joint hinges, which can also be used in hinge 4, and reference is made to these documents.
  • the lever mechanism formed from the levers 8 is covered by a cover element 10 which has a plurality of cover plates 11, 12 and 13, each of which covers a partial area of the lever mechanism.
  • the cover plates 11, 12 and 13 can be moved relative to one another, with a flexible web 14 being provided between the cover plates 11 and 12 and a film hinge 15 between the cover plates 12 and 13.
  • the cover element 10 has a cover plate 11, 12 and 13 on each of the opposite sides of the lever mechanism, so that three cover plates 11, 12 and 13 are provided on each of the opposite sides of the lever mechanism.
  • the cover element 10 is U-shaped in cross section in the area of the cover plates 12 and 13 and has a connecting web 18 on the bottom, on which the film hinge 15 is also formed.
  • the flexible web 14, to which the two cover plates 11 are held, is formed as an extension of the connecting web 18.
  • the first hinge part 5 is provided with a strip-shaped section which is U-shaped in cross section and has a web 51 from which two legs 52 extend essentially at right angles.
  • the U-shaped receptacle thus formed serves to receive a part of the cover element 10 in the closed position, with the cover plates 12 and 13 being arranged within the two legs 52.
  • the first hinge part 5 can be connected to the body 2 at the web 51.
  • a flange 50 is formed on the first hinge part 5, which can also be used to fasten the first hinge part 5.
  • the second hinge part 6 comprises a web 61 which can be fixed to the door 3.
  • An outwardly projecting flange 60 is formed on the web 61 and can also be used for fixing to the door 3.
  • the hinge 4 is shown in a partially opened position, which is between the maximum opening position according to Figure 2 and a closing position according to Figure 4
  • the hinge part 6 has been pivoted relative to the hinge part 5 and the external geometry of the lever mechanism with the levers 8 has therefore changed.
  • the cover plate 11 has also been pivoted relative to the cover plate 12, whereby the overlap area between the cover plates 11 and 12 has been reduced.
  • the slot between the cover plates 12 and 13 has been reduced because the cover plates 12 and 13 have also been pivoted relative to one another.
  • the openings between the levers 8 are covered by the cover plates 11, 12 and 13.
  • the hinge 4 is shown in a closed position.
  • the two webs 51 and 61 of the hinge parts 5 and 6 are essentially parallel and spaced apart from each other.
  • the cover plate 11 is brought into extensive overlap with the cover plate 12, i.e. an overlap of over 80% of the surface of the cover plate 11.
  • the lever mechanism is significantly more compact in the closed position of the hinge 4, so that the cover plates 11, 12 and 13 are arranged more compactly, i.e. have a larger overlap than in a maximally opened area of the hinge 4.
  • the cover plates 11, 12 and 13 lie between the two legs 52 of the U-shaped hinge part 5 when the hinge 4 is closed.
  • cover element 10 is shown without the hinge 4.
  • the cover element 10 is made of a thin material, in particular a film or a thin metal sheet.
  • a polyester film can be used, for example.
  • the cover element 10 For fixing to the lever mechanism, the cover element 10 comprises two tabs 16 and 17 which can be brought into engagement with one another so that the cover element 10 can be fastened to a lever 8 of the lever mechanism. This allows the cover element 10 to be fixed to the lever mechanism in a clamping or locking manner.
  • the tab 16 is partially integral with the cover plate 13 and forms a rigid unit with it.
  • a V-shaped slot is formed between the cover plates 12 and 13 in order to be able to pivot them relative to one another to a certain extent.
  • the cover plate 11 is connected via the flexible web 14 to the connecting web 18, on which the cover plates 12 and 13 extend at an angle, in particular at a right angle.
  • a modified cover element 10 is shown, which is designed as in the first embodiment, but has a bent mounting tab 20 instead of the tabs 16 and 17.
  • the connecting web 18 extends beyond the cover plates 13 and is bent or folded by 180° at a distance from the cover plates 13, so that the mounting tab 20 can be folded over a lever 8 for fixing.
  • the geometry of the cover plate 13 is slightly changed, but otherwise the cover element is designed as in the first embodiment, in particular the cover plate 11 can be pivoted over the bendable web 14 and arranged so that it is covered by the cover plates 12 and 13.
  • FIG 8 a maximum opening position of the hinge 4 is shown, and it can be seen that the cover plate 11 of the cover element 10 is completely spaced from the cover plate 12, so that there is no longer any overlap.
  • the hinge part 6 is moved into the closed position, the cover plate 11 is moved again between the two cover plates 12 of the cover element 10.
  • cover plates 11, 12 and 13 are provided on opposite sides of the lever mechanism. It is of course possible to change the number of cover plates, depending on the geometry of the lever mechanism in the individual positions of the hinge 4.
  • cover plates 11, 12 and 13 can be connected to one another not only by the articulated connection but also by other means, e.g. by insertion tabs. In this way, the cover plates can be prevented from bending away.
