Definitions

  • the invention relates to a hinge device for rotatably holding and moving a door which has at least one door element, a stop hinge for this hinge device and a functional unit, in particular a piece of furniture, with at least one such hinge device.
  • hinge devices that comprise a slidably held stop profile and stop hinges that rotatably connect the stop profile to the door.
  • the US9284761B2 discloses a piece of furniture with a sliding device by means of which a stop profile connected to a folding sliding door can be moved within a door compartment.
  • the folding sliding door comprises two door elements connected to one another by door hinges, of which the first door element is connected to a stop profile at the rear by stop hinges and the second is connected to a guide carriage at the front.
  • the stop profile is held displaceably in a vertical orientation by a sliding device and is provided with support carriages on the top and bottom that are guided in a support rail.
  • the guide carriage can be moved along a guide rail that has three rail sections, of which a first and a second rail section are connected to one another by a third rail section running along a curve. The first rail section runs into the door compartment and the second rail section runs along the front of the piece of furniture.
  • the folding door is extended from the door compartment and unfolded. In the closed position, the door elements are aligned flat to one another. To open the piece of furniture, the folding door is folded back into place, with the door elements in an open position preferably aligned parallel to one another and retracted into the door compartment.
  • the hinge device which connects the stop profile and the Includes stop hinges, adjustable so that the door can be moved vertically and horizontally.
  • the US8336972B2 discloses a hinge device with a stop profile that is provided with adjustable stop hinges. By adjusting the stop hinges, the held door element can be moved horizontally. The vertical adjustment of the door element is carried out by vertical displacement of the stop profile, which is held by an adjustable drive.
  • Another disadvantage is that other device parts that are connected to the stop profile and that fulfill other functions are moved together with the stop profile and may also have to be readjusted.
  • the US8336972B2 also discloses a stop hinge which has a lever mechanism with a mounting lever which is provided with a rack along which a mounting part connected to the door element can be moved by engaging the rack with a screwdriver, which is why signs of wear can occur.
  • the present invention is therefore based on the object of creating an improved hinge device for a functional unit, an improved hinge for this hinge device and an improved functional unit with such a hinge device.
  • the hinge device according to the invention which has a displaceably mounted stop profile and at least two stop hinges connected thereto, should be of simple construction, advantageous to install and easy, convenient and quick to adjust in order to precisely align a door element held by the hinge device, possibly a folding door or folding sliding door, with respect to an opening of a functional unit to be closed.
  • the door or a door element should particularly advantageously be connectable to the hinge device and detachable from it so that installation work or subsequent interventions in the functional unit are easily possible.
  • Drives used to move the stop profile into a door compartment should be designed simply and have reduced dimensions so that the door compartment can be realized with smaller dimensions or so that more space is available for other device parts.
  • a stop hinge should be created for this hinge device, which is robustly constructed and advantageously adjustable. Signs of wear should be avoided with this stop hinge, even after multiple adjustments.
  • the hinge device should allow the held door element to rotate automatically into the end position.
  • the movement of the door element should preferably be dampened so that annoying slamming of the door element is avoided.
  • two adjustable stop hinges should be able to be mounted next to each other or one above the other on the stop profile, which can be adjusted without the adjustment of one stop hinge being hindered by the second stop hinge.
  • the hinge device which is provided for a functional unit which has a door with at least one door element, by means of which a door opening can be completely or partially closed and which can be moved into a door compartment after the door opening has been opened, comprises a stop profile as well as a stop hinge and at least one auxiliary hinge, which on the one hand are detachably connected to the stop profile and on the other hand can be connected to the door element.
  • the stop profile has an anchor channel
  • a support device is provided with a support body which comprises a support anchor which is displaceable in the anchor channel and with at least one locking screw
  • the support device comprises a slider which is slidably mounted in the support body and an adjusting element which is provided for displacing and holding the slider
  • a holding device is provided with a holding body which comprises a holding anchor which is slidably held in the anchor channel and a holding element
  • the stop hinge has a stop body which is supported directly or indirectly on the slider and which is held by the holding element of the holding device after the latter has been displaced against the stop hinge.
  • the auxiliary hinge is preferably identical to the stop hinge, which is why the following statements on the stop hinge also describe the auxiliary hinge in the preferred embodiment.
  • the support anchor of the support device and the holding anchor of the holding device preferably have at least approximately the same cross-section, so that both are held in the anchor channel so that they can be moved but are largely free of play.
  • the holding anchor of the holding device which is preferably made of plastic, preferably has locking elements that prevent the holding device from moving automatically. The holding device can therefore be raised to a point where it is held automatically and can then be moved manually against the stop hinge.
  • the auxiliary hinge is also associated with a holding device which can be moved upwards before the door is mounted and can then also be moved manually against the auxiliary hinge.
  • the support device is first moved to a specified height and fixed.
  • the door element with the stop hinge is then placed on the support device.
  • the holding devices are then moved against the stop hinge and the auxiliary hinge to secure them so that they can no longer come loose from the stop profile.
  • the support device is then adjusted to raise or lower the supported door to the required height.
  • stop hinge and the auxiliary hinge or hinges fixed, preferably using connecting screws.
  • the stop screws provided on the stop body of the stop hinge and the auxiliary hinge are screwed into threaded parts that are provided as one piece in the holding body of the holding device or are integrated into it, if necessary cast in.
  • the door element can therefore be installed conveniently in just a few steps. It is particularly helpful that the door element can be temporarily connected to the stop profile in a first step and secured by moving the holding devices.
  • the adjustment priority can then be easily carried out by operating the adjustable support device and preferably lifting the door element slightly to make it easier to adjust the support device.
  • the support device is preferably self-locking under the load of the door element. The stop screws can then be tightened easily.
  • the stop profile is rod-shaped and preferably has the same profile cross-section over its entire length, which can have additional profile elements in addition to the anchor channel that are suitable for connection to other device parts.
  • an assembly channel is provided into which a connecting part of an upper drive or a lower drive, for example a part of the drive body, can be inserted.
  • the distance between the stop profile and the upper drive and/or the lower drive can be adjusted in stages so that pre-setting is possible. Any remaining deviation from the desired height of the raised door element can then be corrected by actuating the support device.
  • the upper drive and the lower drive are preferably each guided in a retaining rail that runs into the door compartment of the functional unit.
  • a coupling carriage is provided with a carriage body which comprises a carriage anchor which is slidably held in the anchor channel.
  • the cross section of the carriage anchor preferably corresponds to the cross section of the support anchor, so that the The coupling carriage can also be moved within the anchor channel with virtually no play.
  • the coupling carriage which is arranged between the slide and the stop body of the stop hinge, is supported on the underside by the slide and is provided on the top with at least one coupling element that can engage positively in the stop body of the stop hinge.
  • a bearing channel is provided in the slide body, along which the coupling element supported by a support spring can be moved and completely or partially sunk into the slide body.
  • a slide channel and an actuating chamber are preferably provided in the support body.
  • the slide is mounted in the slide channel so that it can be moved axially.
  • the actuating element is rotatably held in the actuating chamber and is connected in a force-fitting manner or as one piece to an eccentrically arranged eccentric part or an eccentrically running eccentric part.
  • the eccentric part is in contact with the slide or a part of it and can move the slide axially outwards when the actuating element is actuated.
  • the slide is returned to the slide channel.
  • the slider has track segments which delimit the at least one guide track into which the eccentric part can engage, which is preferably designed as a spiral which runs eccentrically outwards.
  • the stop body of the stop hinge is connected by a lever mechanism comprising a drive lever, an adjusting lever and an assembly lever to an assembly part, for example a hinge cup, which can be connected to the associated door element.
  • the mounting part can be moved and locked along a displacement axis and has a mounting plate in which a longitudinal opening running parallel to the displacement axis and a guide channel running perpendicular or inclined to the displacement axis are provided.
  • the displacement axis is aligned perpendicular to the stop profile, which is why the raised door element can be moved sideways and also aligned vertically
  • the drive lever which is connected to a drive spring in a force-locking manner, is connected to the stop body on the one hand by a first lever shaft and to a first end piece of the assembly lever on the other hand by a fourth lever shaft.
  • the adjusting lever is connected to the stop body on the one hand by a second lever shaft and to a second end piece of the assembly lever on the other hand by a third lever shaft.
  • the mounting lever is integrally connected, in a force-fitting and/or form-fitting manner, to a mounting body in which an eccentric chamber and a screw chamber are provided.
  • a cylindrical eccentric body is mounted so that it can rotate about a rotation axis, which holds an eccentric part that is spaced from the rotation axis and engages in the guide channel.
  • the eccentric part is, for example, a pin or rod, a rotatably mounted sleeve or a roller.
  • a fixing screw is held in the screw chamber, which penetrates the longitudinal opening in the mounting plate and is connected to a lock nut.
  • the mounting part or the hinge cup can therefore be moved by rotating the eccentric body. During this movement, the position of the fixing screw changes within the longitudinal opening of the mounting plate. The movement of the mounting part is therefore not hindered by the fixing screw. Only after the desired movement of the mounting part has taken place is the fixing screw connected to the lock nut tightened.
  • the longitudinal opening of the mounting plate is preferably connected to a guideway in which the lock nut is held in a rotationally fixed manner.
  • the lock nut is, for example, polygonal, or square, and is recessed into the guideway, which allows the lock nut to be moved but not rotated.
  • the mounting part and the mounting body In order to ensure that the mounting part and the mounting body can be moved against each other precisely and without rotation, they preferably have guide elements that lie against each other and run parallel to the displacement axis.
  • the mounting plate is provided with a guide rib that can engage in a guide groove in the mounting body.
  • the guide channel into which the eccentric part engages is preferably part of an engagement opening which has a receiving opening adjoining the guide channel, the dimensions of which correspond to the dimensions of the eccentric body.
  • the mounting part can therefore be placed on the mounting body regardless of the position of the eccentric body. The eccentric part can easily engage in the receiving opening.
  • the receiving opening has at least one guide edge which runs towards the guide channel and along which the eccentric part guided into the receiving opening is practically automatically guided into the guide channel when the mounting part is displaced relative to the mounting body.
  • a closure part is provided which can be inserted into the engagement opening after the connection of the mounting part to the mounting body in order to enclose the eccentric part within the guide channel.
  • the stop body has a damping chamber in which a damping element is arranged, which comprises a damping cylinder and a damping piston with a piston rod guided therein.
  • a damping element is an oil damper or a pneumatic damper, which prevents the stop hinge from making jerky movements.
  • the damping element To actuate the damping element, it is provided with a transmission part that interacts with an actuating arm that is preferably provided on the drive lever, which is driven by a drive spring.
  • the drive spring has, for example, two spring assemblies connected to one another by a spring center piece, through which the first lever shaft is guided.
  • the end pieces of the spring assemblies are preferably anchored to the stop body of the stop hinge, while the spring center piece acts on the drive lever.
  • the functional unit has at least one single-part or multi-part door, such as a folding door, each of which is held by a hinge device according to the invention and can preferably be inserted into a door compartment.
