Description
[0001]Hinge device, stop hinge and functional unit The invention relates to a hinge device for holding a door which has at least one door element, a stop hinge for this hinge device is provided and a functional unit, in particular a piece of furniture, with at least one such hinge device. To close functional units which have a door with at least one door element and a door compartment into which the door can be slid after the functional unit has been opened, hinge devices are used which comprise a slidably held stop profile and stop hinges which rotatably connect the stop profile to the door. 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 slid 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 door element is connected to a guide track at the front. The stop profile is held vertically by a sliding device and is provided with support tracks on the top and bottom that are guided in a support rail. The guide track 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 that runs 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. To close the piece of furniture, the folding door is extended out of the door compartment and unfolded.In the closed position, the door elements are aligned flat with one another. To open the piece of furniture, the folding door is folded closed again, with the door elements preferably aligned parallel to one another in the open position and retracted into the door compartment. To ensure that the functional unit and the associated door element can be precisely opened, it is generally necessary for the hinge device, which comprises the stop profile and the stop hinges, to be adjustable so that the door can be moved vertically and horizontally. HAWA 23-02 PCT / 06.03.24 US8336972B2 discloses a hinge device with a stop profile 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 achieved by vertically moving the stop profile, which is held by an adjustable running gear.This results in the disadvantage that a correspondingly designed, adjustable carriage is required, which is correspondingly complex and requires larger dimensions to allow for the integration of an adjustment device. Another disadvantage is that adjusting this hinge device is relatively complex. Typically, the door element must be lifted with aids until the adjustment is complete. Another disadvantage is that other device components connected to the stop profile and which fulfill other functions are moved along with the stop profile and may also need to be readjusted.US8336972B2 also discloses a stop hinge comprising a lever mechanism with a mounting lever provided with a toothed rack along which a mounting part connected to the door element can be displaced by engaging the rack with a screwdriver, which can lead to wear. US9057216B2 discloses a hinge device with a stop profile provided with stop hinges. The stop hinges are detachable, manually displaceable, and re-fixable. 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 slidably mounted stop profile and at least two stop hinges connected thereto, is intended to be simple in design, advantageously installable, and easily, conveniently, and quickly adjustable to precisely align a door element held by the hinge device, possibly a folding door or folding-sliding door (HAWA 23-02 PCT / 06.03.24), with respect to an opening of a functional unit that is to be closed. The door or a door element is particularly advantageously intended to be connectable to and detachable from the hinge device, so that installation work or subsequent interventions in the functional unit are easily possible.Running gears that are used to move the stop profile into a door compartment should be simple in design and have reduced dimensions so that the door compartment can be made smaller or so that more space is available for other device components. Furthermore, a stop hinge for this hinge device should be created that is robustly constructed and advantageously adjustable. Signs of wear should be avoided with this stop hinge, even after repeated adjustments. The hinge device should allow the held door element to be rotated 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. Furthermore, two adjustable stop hinges should be installed next to each other or one behind the other to carry higher loads.be mountable 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. This object is achieved with a hinge device according to claim 1, an improved stop hinge according to claim 13 and a functional unit, optionally a piece of furniture, according to claim 15. Advantageous embodiments of the invention are specified in further claims. The hinge device, which is provided for a functional unit having a door with at least one door element, by means of which a door opening can be fully 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. HAWA 23-02 PCT / 06.03.24 According to the invention, the stop profile has an anchor channel; a support device is provided with a support body which comprises a support anchor which is displaceably held in the anchor channel and lockable by at least one locking screw; the support device comprises a slide which is displaceably mounted in the support body and an adjusting element which is provided for displacing and holding the slide; a holding device is provided with a holding body which comprises a holding anchor which is displaceably held in the anchor channel and a holding element; and the stop hinge has a stop body which is supported directly or indirectly on the slide 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 regarding the stop hinge also describe the auxiliary hinge in the preferred embodiment. The support anchor of the support device and the retaining anchor of the retaining 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 largely free of play. The retaining anchor of the retaining device, which is preferably made of plastic, preferably has locking elements that prevent the retaining device from moving automatically. The retaining device can therefore be raised to a point where it is held automatically and can subsequently be manually moved against the stop hinge.Preferably, the auxiliary hinge is also assigned a holding device, which can be moved upwards before the door is installed and then also manually moved against the auxiliary hinge. However, it is sufficient to provide a support device only for the stop hinge. This has the advantage that the height adjustment of the stop hinge and thus of the held door element and the at least one auxiliary hinge takes place on only one support device, thus avoiding multiple adjustments. To install the door element, on which the stop hinge and the at least one auxiliary hinge are pre-assembled, the support device is first moved to a specified height and secured. The door element with the stop hinge is then placed on the support device. HAWA 23-02 PCT / 06.03.24 The holding devices are then moved against the stop hinge and the auxiliary hinge to secure them, preventing them from coming loose from the stop profile. The support device is then adjusted to raise or lower the supported door to the required height. Only after the support device has been correctly adjusted are the stop hinge and the auxiliary hinge(s) secured, preferably using connecting screws. The stop screws, which are provided on the stop body of the stop hinge and the auxiliary hinge, are screwed into threaded parts that are integrally provided in the holding body of the holding device or are integrated into it, or even cast in if necessary. The door element can therefore be installed conveniently in just a few steps.It is particularly helpful that the door element can be provisionally 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 actuating the adjustable support device and preferably slightly lifting the door element to facilitate the adjustment of the support device. The support device is preferably self-locking under the load of the door element. The stop screws can then be easily tightened. The stop profile is rod-shaped and preferably has the same profile cross-section over its entire length. In addition to the anchor channel, this profile can have further profile elements suitable for connection to other device parts.For example, a mounting channel is provided into which a connecting part of an upper or lower drive, for example a part of the drive body, can be inserted. In preferred embodiments, the distance between the stop profile and the upper and / or lower drive is adjustable in steps, so that pre-setting is possible. Any remaining deviation from the desired height of the raised door element can subsequently be corrected by actuating the support device. The upper drive and the lower drive are preferably each guided in a retaining rail that extends into the door compartment of the functional unit. HAWA 23-02 PCT / 06.03.24 In preferred embodiments, a coupling carriage with a carriage body is provided, which comprises a carriage anchor that is slidably held in the anchor channel.The cross-section of the slide anchor preferably corresponds to the cross-section of the support anchor, so that the coupling slide can also be moved within the anchor channel with virtually no play. The coupling slide, which is arranged between the slide and the stop body of the stop hinge, is supported on the underside by the slide and provided on the top with at least one coupling element that can engage positively with the stop body of the stop hinge. This has the advantage that the slide of the support device is held by the coupling slide, and forces are therefore only transmitted axially to the slide. In a preferred embodiment, a bearing channel is provided in the slide body, along which the coupling element, supported by a support spring, can be moved and fully or partially lowered into the slide body.This has the advantage that the stop body of the stop hinge does not have to be lifted above the coupling element during installation, but can displace it downwards. A slide channel and an actuating chamber are preferably provided in the support body. The slide is mounted so that it can be moved axially in the slide channel. 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. When the actuating element is rotated in the other direction, the slide is returned to the slide channel.In preferred embodiments, the slider has track segments that delimit the at least one guide track into which the eccentric part can engage. The eccentric part is preferably designed as a spiral that extends eccentrically outwards. The stop body of the stop hinge is connected to a mounting part, for example a hinge cup, by a lever mechanism comprising a drive lever, an adjusting lever, and a mounting lever. The mounting part can be displaced and locked along a displacement axis and, for this purpose, 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 laterally and also aligned vertically. The drive lever, which is non-positively connected to a drive spring, is connected on the one hand by a first lever shaft to the stop body and on the other hand by a fourth lever shaft to a first end piece of the mounting lever. The adjusting lever is connected on the one hand by a second lever shaft to the stop body and on the other hand by a third lever shaft to a second end piece of the mounting lever. The mounting lever is connected in one piece, non-positively and / or positively to a mounting body in which an eccentric chamber and a screw chamber are provided. In the eccentric chamber, a cylindrical eccentric body is mounted so as to be rotatable about a rotation axis. This cylindrical eccentric body holds an eccentric part which is spaced apart from the rotation axis and engages in the guide channel.The eccentric part can be 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 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 occurred is the fixing screw connected to the lock nut tightened. If two adjustable stop hinges are arranged next to or on top of each other, the fixing screws are not tightened until both stop hinges have been adjusted. This prevents the stop hinges from interfering with each other during adjustment.The stop hinges are therefore not self-locking. HAWA 23-02 PCT / 06.03.24 The longitudinal opening of the mounting plate is preferably connected to a guide track in which the lock nut is held in a rotationally fixed manner. The lock nut is, for example, polygonal or square, and countersunk into the guide track, which allows the lock nut to be moved but not rotated. To ensure that the mounting part and the mounting body can be moved precisely and without rotation relative to one another, they preferably have guide elements that rest against one another and run parallel to the movement axis. For example, the mounting plate is provided with a guide rib that can engage 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 and whose dimensions correspond to the dimensions of the eccentric body. Regardless of the position of the eccentric body, the mounting part can therefore be placed onto the mounting 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, which is guided into the receiving opening, is practically automatically inserted into the guide channel when the mounting part is displaced relative to the mounting body. Preferably, a closure part is provided which can be inserted into the engagement opening after the mounting part has been connected to the mounting body in order to enclose the eccentric part within the guide channel.In a further preferred embodiment, 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. For example, the damping element is an oil damper or a pneumatic damper, which prevents the stop hinge from performing jerky movements. To actuate the damping element, it is provided with a transmission part that interacts with an actuating arm, which is preferably provided on the drive lever and driven by a drive spring. The drive spring has, for example, two spring assemblies connected to one another by a spring center piece HAWA 23-02 PCT / 06.03.24, 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 retracted into a door compartment. The invention is explained in more detail below with reference to drawings.

Fig. 9b shows the stop hinge of Fig. 9a without stop body 30 and with mounted mounting part 38; Fig. 9c shows the stop hinge 3 of Fig. 9a without stop body 30 and with detached mounting part 38; Fig. 9d shows the stop hinge of Fig. 9c without stop body 30 and with mounted mounting part 38; Fig. 10 shows the stop hinge 3 of Fig. 9a in an exploded view; Fig. 11a shows the stop hinge 3 of Fig. 3a in a preferred embodiment with a stop body 30', which is provided for positive engagement in the stop profile 21; Fig.11b shows the stop hinge 3 of Fig. 11a with the mounting part 38 removed and a locking element 39, by means of which the engagement opening 3850 can be closed; and HAWA 23-02 PCT / 06.03.24 Fig. 11c shows the mounting part 38 and the locking element 39 of Fig. 11b from the other side. Fig. 1 shows a functional unit 1 according to the invention in the design of a piece of furniture with a first hinge device 2, which has a stop profile 21 and a stop hinge 3 and an auxiliary hinge 3' mounted thereon, and with a second hinge device 2', which has a stop profile 21 and a stop hinge 3 and an auxiliary hinge 3' mounted thereon, and with a folding sliding door 11, which is held by the first hinge device 2 so as to be rotatable and displaceable into an associated door compartment 10, and with a single door 11', which is held by the second hinge device 2' so as to be rotatable and displaceable into an associated door compartment 10.In this preferred embodiment, the piece of furniture 1 has side walls 1A, a top panel 1B, a bottom panel 1C, an intermediate panel 1E, and partition walls 1D, each of which defines a door compartment 10 with one of the side walls 1A. The folding door 11 has a first door element 111, which is connected on one side by stop hinges 3 to a stop profile 21, and on the other side by door hinges 14 to a second door element 112, the dimensions of which preferably correspond to the dimensions of the first door element 111. The folding door 11 is slightly unfolded and can either be fully folded and retracted into the door compartment 10 with the door elements 111, 112 aligned parallel to one another, or fully unfolded and moved into a closed position in which the two door elements 111, 112 are at least approximately aligned in one plane. In the embodiment of Fig.1, the stop profile 12 is held in a vertical orientation by a sliding device 19, which is shown schematically, and is movable within the associated door compartment 10. The doors 11 are aligned parallel to the side wall 1A in front of the associated door compartment 10 and can subsequently be moved into the door compartment 10. For movement within the door compartment 10, each stop profile 12 can also be provided with drive devices. Preferably, the stop profile 12 is connected at the top to an upper support carriage 5, which can be moved along an associated support rail 12 into the door compartment 10. At the bottom, the stop profile 21 is preferably connected to a lower carriage 5', which is guided in a lower support rail 12'. The load of the folding door 11 is therefore transferred from the stop profile 21 to the support rails 12, 12' HAWA 23-02 PCT / 06.03.24, which is why the sliding device 19 only has to absorb tilting moments.The second door element 112 of the folding door 11 is connected at its leading edge to a guide carriage 15, which is guided in a guide rail 13 comprising a first rail section 131 extending into the door compartment 10 and a second rail section 132 extending along the front of the piece of furniture 1. The folding door 11 is therefore held at the front by means of the guide carriage 15, which can be moved along the front of the piece of furniture 1 when the folding door 11 is unfolded and into the door compartment 10 when the folding door 11 is folded closed. The guide carriage 15 always precedes the second door element 112 in the direction of movement. The hinge device 2 according to the invention, which comprises the stop profile 21 and the stop hinge 3 and, in this embodiment, also an auxiliary hinge 3', is shown schematically.The stop hinge 3 and the auxiliary hinge 3' are preferably identically designed and each comprise a stop body 30, which is provided for connection to the stop profile 21. To connect the stop hinge 3 to the mounting profile 21, an adjustable support device 22 is provided, which is held in a form-fitting manner by first profile elements of the mounting profile 21 and is displaceable along the mounting profile 21 and can be fixed at a predetermined location. Furthermore, a holding device 24 is each provided for the stop hinge 3 and the auxiliary hinge 3', which are also held in a form-fitting manner by the first profile elements of the mounting profile 21 and are displaceable along the mounting profile 21 in order to hold the stop hinge 3 and the auxiliary hinge 3' placed on the support device 22 in a form-fitting manner.Since the folding door 11 and the individual door 11' are each held by the associated support device 22, on which the stop hinge 3 is supported, it is preferably omitted to also assign a support device 22 to the auxiliary hinges 3'. A single adjustable support device 22 is therefore sufficient to adjust the height of the folding door 11 and the individual door 11', which is why only this support device 22 needs to be adjusted. Fig. 2 shows the first hinge device 2 of Fig. 1 with a part of the first door element 111 of the folding door 11 in a preferred embodiment. The door element 11 is held by mounting parts 38 of the stop hinge 3 and the HAWA 23-02 PCT / 06.03.24 auxiliary hinge 3'. The mounting parts 38 are preferably designed as hinge cups, but can also have other shapes. The stop profile 21 is connected at the top to an upper support carriage 5, which is guided in an upper support rail 12 by means of support rollers 51 and guide rollers 52.Preferably, as shown in Fig. 1, the stop profile 21 is also connected on the underside to a support carriage 5', which is guided in a lower support rail 12'. The support carriage 5 has a carriage body 50, which is provided on the underside with a connecting part 53, which in this embodiment is inserted into a mounting channel 211 (see Fig. 6a) of the stop profile 21. The displacement device 19, which can be designed as desired, is not shown in Fig. 2. The stop hinge 3 is placed with the stop body 30 on the support device 22, and the holding devices 24 are moved against the stop bodies 30 of the stop hinge 3 and the auxiliary hinge 3' to hold them in a form-fitting manner. The stop profile 21 has an outwardly open anchor channel 210 with profile elements that define a relatively narrow slot and enable the holding of anchor elements.Figures 6a and 6b show that the support device 22 has a support body 220 comprising a support anchor 2201, which is slidably held in the anchor channel 210 and lockable with at least one locking screw 2208. Furthermore, the support device 22 comprises a slide 221, which is slidably mounted in the support body 220, and an adjusting element 225, which is provided for displacing and holding the slide 221. The holding device 24 has a holding body 240, which comprises a holding anchor 2401, which is slidably held in the anchor channel 210, and a holding element 241, which can engage positively in the stop body 30 of the stop hinge 3 or the auxiliary hinge 3' or can partially enclose the stop body 30. The holding body 240 is made of metal or, preferably, of plastic, such as polyoxymethylene POM. The holding anchor 2401 is formed by the side pieces of the holding body 240.The retaining anchor 2401 of the plastic retaining body 240 is additionally provided with lateral extensions 24011, which act as locking elements to prevent the automatic displacement of the retaining device 24 HAWA 23-02 PCT / 06.03.24. Recesses 24000 are provided in the retaining body 240 to allow the locking elements 24011 to be displaced and act in a spring-elastic manner. In this embodiment, the retaining anchor 2401 therefore has four spring-elastic locking elements 24011, which can exert a force laterally outward. In this preferred embodiment, the retaining element 241 is fork-shaped and arranged at the upper end of the retaining device 24.The holding body 240 is an elongated plate provided on the top and bottom with threaded parts 2408 arranged at a distance from one another corresponding to the distance between two stop screws 308 inserted into the stop body 30 of the stop hinge 3 or auxiliary hinge 3'. The threaded parts 2408 can be machined into the holding body 240 with a thread cutter or can be inserted and cast as metal pieces into receiving openings 2400, as shown in Fig. 4a. In Fig. 2, the stop hinge 3 has already been placed onto the support device 22 in a first installation step. In a second installation step, the holding devices 24 were moved against the stop bodies 30 of the stop hinge 3 and the auxiliary hinge 3' in order to hold and secure them in a form-fitting manner. The adjustment of the hinge device 2 can now be carried out easily.In a first step A, the adjusting element 225 of the support device 22 is actuated using a tool to move the stop hinge 3 and thus the door element 111 vertically to the desired height. After the height adjustment has been completed, in a second step B, the stop screws 308 are tightened, which are screwed into the threaded parts 2408 of the holding devices 24 in order to firmly connect the stop hinge 3 and the auxiliary hinge 3' each to the associated holding device 24. After this process, the stop hinge 3 and the auxiliary hinge 3' are firmly connected to the stop profile 21. In a third step C, an eccentric body 385 provided in the stop hinge 3 and the auxiliary hinge 3' is actuated to move the mounting part 38 perpendicular to the stop profile 21. This allows the distance of the door element 111 from the stop profile 21 to be adjusted. In addition, the door element 111 can be aligned exactly vertically.HAWA 23-02 PCT / 06.03.24 After the adjustment is completed, the mounting part 38 is locked in a fourth step D by tightening a fixing screw 381. Preferably, the stop hinge 3 and the auxiliary hinge 3', which are preferably identical, are adjusted before the fixing screws 381 are tightened. In a fifth step E, a preferably provided stop screw 315 on the stop hinge 3 and the auxiliary hinge 3' can also be actuated to limit the maximum deflection of the door element 111. Fig. 3a shows the hinge device 2 of Fig. 2 with the stop hinge 3 released from the stop profile 21 and the auxiliary hinge 3' released from the stop profile 21 in a preferred embodiment. The stop screws 308 have been loosened, and the holding devices 24 have been moved upward into a position in which they are held. The hinges 3, 3' and the associated door element 111 could thus be removed.In this preferred embodiment, a coupling carriage 23 is provided with a carriage body 230, which comprises a carriage anchor 2301 (see Fig. 6a and Fig. 6b), which is slidably held in the anchor channel 210 of the stop profile 21 and which rests against the upper side of the slide 221. Upon actuation of the support device 22, the coupling carriage 23 is also displaced vertically together with the slide 221. In this embodiment, the stop body 30 of the stop hinge 3 is therefore not placed directly on the slide 221, but on the coupling carriage 23. The slide 221 therefore only has to absorb vertically acting forces and is thus protected against disruptive forces. To hold the stop body 30, the coupling device 23 is provided with a coupling element 231 which can engage in the coupling body 30 of the stop hinge 3 in order to hold it in a form-fitting manner.Before inserting the hinges 3, 3', the support device 22 is adjusted to the intended height and fixed by tightening the locking screws 2208 of the support body 220, which are clamped to the stop profile 21. Any remaining height deviation can now be corrected after assembly of the door element 111 by adjusting the support device 22. Fig. 3b shows the hinge device 2 from Fig. 3a with the stop hinge 3 and the auxiliary hinge 3' after connection to the HAWA 23-02 PCT / 06.03.24 stop profile 21. The holding devices 24 have been moved downward. After completing the height adjustment, the stop screws 308 are finally tightened. Fig. 4a shows the hinge device 2 from Fig. 3a with only the stop hinge 3, without the stop profile 21 and the auxiliary hinge 3'.It is shown that the holding element 241 of the holding device 24 and the coupling element 231 of the coupling device 23 are fork-shaped and can engage positively in recesses 300 provided on both sides of the end pieces of the stop body 30. The stop body 30 is connected by lever shafts to a first end piece of a drive lever 31 and a first end piece of an adjusting lever 32, the second end pieces of which are connected by further lever shafts to a mounting lever 33. The mounting lever 33 is connected to a mounting body 338, on which the mounting part 38 is slidably and lockably mounted. Fig. 4b shows part of the stop hinge 3 of Fig.4a with the stop body 30, which has indentations 300 on a lower end piece into which the coupling carriage 23 can engage with coupling elements 231, and which has indentations 300 on an upper end piece into which the holding device 24 can engage with holding elements 241. Also shown are the first lever shaft 361, which is provided for holding the drive lever 31, and the second lever shaft 362, which is provided for holding the adjusting lever 32. The drive lever 31 and the adjusting lever 32 are cut in the middle. Also shown is a drive spring 35, which encloses the first lever shaft 361 and has two spring assemblies 353 (only one shown), which are connected to one another on one side by a spring center piece 352 and which each have a spring end piece 351 at the other end. The spring end pieces 351 are anchored to the stop body 30, while the spring center piece 352 is connected to the drive lever 31. Fig.Fig. 5a shows the left side of the hinge device 2 of Fig. 4a without the stop profile 21. It is shown that the coupling element 231 of the coupling slide 23 and the holding element 241 of the holding device 24 engage in the corresponding recesses 300 of the stop body 30. Fig. 5b shows a longitudinal section through the hinge device 2 of Fig. 5a. The stop screws 308 are screwed into the threaded parts 2408 of the holding body HAWA 23-02 PCT / 06.03.24 240, so that the stop hinge 3 is firmly connected to the holding device 24. The section through the stop body 30 reveals a view of a damping element 37, which is arranged in a damping chamber 3000 of the stop body 30 and is held axially displaceably by a bearing plate 3001.The damping element 37 comprises a damping cylinder 371 and a damping piston 374 guided therein, which is connected to a piston rod 372, as well as a transmission part 373, which is connected to the damping cylinder 371 and has a guide flank 3730 facing away from the damping cylinder 371. As shown in Fig. 10, the drive lever 31 has an actuating arm 317, which, upon rotation of the drive lever 31, acts on the transmission part 373 and axially displaces the damping cylinder 371, while the piston rod 372 rests against a stop 3002 within the damping chamber 3000. The actuation of the drive lever 31 is thus damped. When the damping piston 374 is actuated, a return spring 375 is also actuated, which returns the damping piston 374 as soon as the drive lever 31 is turned back again.A bearing channel 2300 is provided in the slide body 230, in which the coupling element 231, which rests against a support spring 232, is slidably mounted and can be fully or partially retracted into the slide body 230. When the stop body 30 of the stop hinge 3 is guided against the coupling element 231, the latter is displaced into the coupling body 230 until it can be pushed back into a recess 300 of the stop body 30 by the support spring 232. The coupling device 23 further comprises a cover 236, which is connected to the coupling body 230 by at least one locking screw 2361. The cover 236 can also form a wall of the bearing channel 2300. The support body 220 of the support device 22 comprises a slide channel 2200 in which the slide 221 is mounted so as to be axially displaceable, and an actuating chamber 2250 within which the actuating element 225 is rotatably held.The adjusting element 225 is provided, either force-fitting or integrally, with an eccentrically arranged eccentric part or an eccentrically extending eccentric part, which is in contact with the slide 221 or a part thereof. HAWA 23-02 PCT / 06.03.24 Fig. 5b further shows that the support body 220 and the slide body 230, in this preferred embodiment, are optionally connected to one another by a connecting bolt 239. The bolt head 2391 of the connecting bolt 239 is slidably held within the slide body 230 in a bolt chamber 2390, so that the coupling device 23 can be displaced from the support device 22 by the required amount. Fig. 6a shows the hinge device 2 of Fig. 4a in an exploded view with sections of the stop profile 21, but without the stop hinge 3.It is shown that the support anchor 2201, the slide anchor 2301, and the retaining anchor 2401 are held in a form-fitting manner in the anchor channel 210 of the stop profile 21. Fig. 6b shows the hinge device 2 of Fig. 6a from the other side without the sections of the stop profile 21. Fig. 7a shows the adjustable support device 22 of Fig. 3a with the support body 220, which has the support anchor 2201 and the slide 221 mounted axially displaceably in the support body 220 and displaceable by means of the adjusting element 225. The cover 226 and the connecting screws 2261 are detached from the support body 220, so that the slide channel 2200 is exposed. The cover 226 therefore forms a side wall of the slide channel 2200. Fig. 7b shows the slide 221 of Fig. 7a, which has track segments 2211, and the adjusting element 225, which is provided with a spiral 2251. Guide tracks 2210 are formed between the track segments 2211, into which the spiral 2251 can engage. Fig.Fig. 7c shows the adjusting element 225 with the slide 221 of Fig. 7a almost fully extended. Fig. 7d shows the slide 221 of Fig. 7c after a counterclockwise rotation of the adjusting element 225. Fig. 8 shows the coupling carriage 23 of Fig. 3a with a cover 236 held by locking screws 2361 and shown in a sectional view, with a view of the fork-shaped coupling element 231, which in this preferred embodiment is slidably mounted and supported by a spring 232. The coupling element 231 is partially extended from the bearing channel 2300. The exposed space in the bearing channel 2300 shows that the coupling element 231 can be fully slid into the carriage body 230. HAWA 23-02 PCT / 06.03.24 Alternatively, the coupling element 231 can also be integrally connected to the slide body 230 in a form-fitting or force-fitting manner.Preferably, the carriage device 23 is manufactured in one piece, for example, as a cast part. Fig. 9a shows the stop hinge 3 of Fig. 3a without the stop body 30. Fig. 10 shows the stop hinge 3 in an exploded view. Figs. 9a and 10 show that the stop hinge 3 has four lever shafts 361, 362, 363, 364, by means of which the stop body 30, a first drive lever 31, an adjusting lever 32, and a mounting lever 33 are connected to one another. The mounting lever 33 is connected to a mounting body 338, from which the mounting part 38 has been removed, and in which an eccentric chamber 3385 and a screw chamber 3381 are provided. The mounting part 38 and the mounting body 338 can be connected to one another in a form-fitting manner and can be displaced relative to one another and for this purpose have corresponding guide elements 386, 3386 as well as mutually adjacent running surfaces.The mounting body 338 has a guide groove 3386 into which a guide rib 386 connected to the mounting part 38 can engage. The guide elements can be designed as desired and provided as needed. The mounting part 38 comprises a mounting plate 388 in which a longitudinal opening 3810 running parallel to the displacement axis y and a guide channel 3801 running perpendicular or inclined to the displacement axis y are provided. A cylindrical eccentric body 385 is mounted in the eccentric chamber 3385 for rotation about a rotation axis x. The eccentric body 385 holds an eccentric part 3851, which is rod-shaped or cylindrical and engages in the guide channel 3801, at a distance from the rotation axis x. A fixing screw 381 is held in the screw chamber 3381, which can be passed through the longitudinal opening 3810 and connected to a lock nut on the other side in order to firmly connect the mounting part 38 to the mounting body 338.The longitudinal opening 3810 is enclosed by a guide track 38100, which is recessed into the mounting plate 388. The guide track 38100 is rectangular and is designed to hold the lock nut 3811 in a movable but non-rotatable manner. The fixing screw 381 can therefore be tightened without the lock nut 3811 rotating. The guide channel 3801 is part of an engagement opening 380, which has a receiving opening 3800 adjoining the guide channel 3801, the dimensions of which preferably correspond to the dimensions of the eccentric body 385. In addition, the receiving opening 3800 preferably has at least one guide edge 3802, along which the eccentric part 3851 guided into the receiving opening 3800 can be inserted into the guide channel 3801 when the mounting part 38 is displaced.The mounting part 38 can therefore be placed on the mounting body 338 and moved along the displacement axis y, whereby the eccentric part 3851 is automatically guided into the guide channel 3801. After the mounting part 38 has been placed, the engagement opening 380 can be covered by a closure part 39, which has a cover 390 and a closure body 391, by means of which the guide channel 3801 can be closed. After the closure part 39 has been placed, the eccentric part 3851 is held within the guide channel 3801. The closure part 39 is further provided with clamp elements that can engage over the edge of the engagement opening 380 and hold the closure part 39 in position. It is also shown that the cover 390 can be countersunk into a recess in the mounting plate 388. Fig. 9b shows the stop hinge of Fig. 9a without stop body 30 and with mounted mounting part 38. The eccentric part 3851 is held in the guide channel 3801.The fixing screw 381 is passed through the longitudinal opening 3810 and connected to the lock nut 3811. Fig. 9c shows the stop hinge 3 of Fig. 9a without the stop body 30 and with the mounting part 38 removed. The eccentric body 385 and the fixing screw 381 have been removed from the mounting body 388 and are shown separately. Fig. 9d shows the stop hinge of Fig. 9c without the stop body 30 and with the mounting part 38 mounted. Fig. 10 shows the stop hinge 3 of Fig. 9a in an exploded view. Dash-dotted lines symbolize how the stop body 30, the drive lever 31, the adjusting lever 32, and the mounting lever 33 are connected to one another using the four lever shafts 361, 362, 363, 364. The fixing screw 381 is inserted into the mounting body HAWA 23-02 PCT / 06.03.24 338 from the rear, as shown. The eccentric body 385 is inserted into the mounting body 338 from the front, as shown. Fig.11a shows the stop hinge 3 of Fig. 3a in a preferred embodiment with a stop body 30', which is intended for positive engagement with the stop profile 21. The stop body 30' is provided with claw-shaped end pieces that can engage with the stop profile 21, provided that the latter is provided with corresponding profile parts. Threaded bolts can be inserted into the openings shown, which are clamped to the stop profile 21 to fix the stop hinge 3. Furthermore, it is shown that the stop body 30' also preferably has a damping chamber 3000, into which the damping element 37 can be inserted. The stop body 30, for example, according to Fig. 4b, can therefore be replaced by the stop body 30' of Fig. 11a, and vice versa. Fig. 11b shows the stop hinge 3 of Fig. 11a with the mounting part 38 removed and a locking element 39, by means of which the engagement opening 3850 can be closed. Fig.Fig. 11c shows the mounting part 38 and the locking element 39 of Fig. 11b from the other side.
