Description
[0001]Guide device, guide carriage, and functional unit. The invention relates to a guide device comprising a guide carriage having a coupling device and connectable to a separating element of a functional unit by a connecting device. Furthermore, the invention relates to such a guide carriage and to a functional unit, for example, a piece of furniture, provided with such a guide device. To close off functional units, such as openings in rooms or pieces of furniture, separating elements, optionally foldable separating elements, such as folding doors or folding-sliding doors, are used. Preferably, separating elements are provided which, after the opening has been cleared, are pushed into a door compartment so as not to be obtrusive. US9284761B2 discloses a piece of furniture with a sliding device by means of which a mounting profile connected to a folding-sliding door can be moved within a door compartment. The folding-sliding doorcomprises two door elements, of which the first door element is connected at the rear by stop hinges to the mounting profile and at the front to the rear of a second door element. The second door element is connected at the front by a connecting device to a guide carriage of a guide device, which is slidably mounted in a guide rail. The connecting device comprises a hinge with a hinge lever, which is rotatably connected to a hinge cup by a first lever end piece and connectable to the carriage body of the guide carriage by a second lever end piece. The first end piece comprises a receiving sleeve into which a hinge shaft is inserted. The second lever end piece comprises a lever block with a threaded hole into which a mounting bolt is screwed, which can be hooked into the carriage body of the guide carriage. The connection of the folding sliding door to the guide carriage by hooking theMounting the connecting device's mounting bolt into the guide carriage body is not easy and requires skill. US2020018106A1, US2021262266A1, and US2022307305A1 disclose further guide devices with a guide carriage having a coupling device to which a connecting device can be coupled, which can be connected to a separating element by a rotatably mounted hinge part. HAWA 23-04 PCT / 26.04.24 The coupling device of the guide carriage of US2020018106A1 comprises a support having an upper and a lower bearing element. The connecting device, which is connected to a door, has hooks on the top and bottom sides that can be hooked into the bearing elements. The coupling device of the guide carriage of US2021262266A1 also comprises a carrier having an upper and a lower bearing element. The connecting device connected to a door hasthe top side has hooks that can be hooked into the upper bearing element. On the underside, the connecting device has a locking device that can be connected to the lower bearing element. Hanging the door with these connecting devices on the guide carriage is also not easy to carry out, since the connecting device must first be hooked onto the upper bearing element and then, if necessary by rotating the door element, also connected to the lower bearing element. The guide carriage with the coupling device and the connecting device are also relatively complex and take up a relatively large amount of space. The coupling device of the guide carriage of US2022307305A1 comprises a carrier, which has an upper and a lower bearing element, into which in turn a connecting device can be hooked. The bearing elements are held by a locking element, which has a locking part with aLocking contour and which is rotatably and slidably mounted. The locking element can be rotated outwards with the upper bearing element, which allows the connecting device, which includes a locking bolt, to be more conveniently hooked in. After hooking the connecting device connected to the door, the locking element is rotated back. During this process, the locking bolt is engaged in the locking contour. The rotatable and slidable mounting of the locking element and the additional arrangement of a locking bolt and a locking contour, in turn, leads to a relatively complex design of this device, which in turn takes up a relatively large amount of space. The coupling devices of the guide carriages of US2020018106A1, US2021262266A1, and US2022307305A1 each comprise a carrier which is connected to the part of the carriage body of the guide carriages by a horizontally aligned connecting web.which holds the support rollers and HAWA 23-04 PCT / 26.04.24 guide rollers. The coupling device with the support is therefore spaced from the guide carriage by the connecting web, which is why the guide carriage with the coupling device takes up a particularly large amount of space. Furthermore, it should be noted that the coupling devices and connecting devices of US2020018106A1, US2021262266A1, and US2022307305A1 include numerous manufacturer-specific device components that must be robustly designed with regard to the load to be carried by the partition element. The manufacture and assembly of this device is therefore correspondingly complex. The use of conventional hinges, which have a simple hinge lever, is also impossible or almost impossible with these connecting devices. Furthermore, these devices lack a means of easily adjusting the height of the door element connected to the guide carriage.The present invention is therefore based on the object of creating an improved guide device with an improved guide carriage, which has a coupling device and can be connected to a connecting device that is mounted on a separating element. Furthermore, a functional unit with such a guide device and such a guide carriage is to be created. The guide device according to the invention should allow a separating element, in particular a sliding door, to be detachably connected by means of a connecting device in a simple manner to a guide carriage, which has a coupling device and is displaceably mounted in a guide rail. During this process, the separating element should be able to be connected to the guide carriage without it having to be rotated or tilted. The process of connecting and detaching the separating element should be easy to carry out. The guide carriage, which has at least one support roller andpreferably has at least one guide roller and / or at least one stabilizing roller, should be of simple and robust construction and have a coupling device that takes up little space and hardly protrudes from the carriage body. A support that is connected to the carriage body by a connecting web should be avoided if possible. The carriage body and the coupling device should practically form a HAWA 23-04 PCT / 26.04.24 unit, at least after the coupling of the connecting device, so that the coupling device results in only a minimal enlargement of the guide carriage. The connecting device, which can be connected to the separating element by a hinge, should also be of simple and compact robust construction so that it takes up little space. The connecting device and the coupling device should also allow conventional hinges to be easily connected to theGuide carriage. Device components that perform complex movements, such as rotation combined with displacement, and which are correspondingly complex to implement and store, should be avoided. In addition, the connecting device and the coupling device should be able to be constructed with as few device components as possible, so that manufacturing costs and space requirements can be reduced. Despite the small space requirement, the device components should also be able to be designed to be stable, so that deformations are avoided, especially when mounting heavier separating elements. The guide device should require hardly any maintenance, even after extended operation. The guide device should ideally allow the held separating element to be easily adjusted, and in particular its height to be set. Furthermore, the guide carriage should be easy to adapt to any type of running rail or guide rail.This object is achieved with a guide device according to claim 1, a guide carriage according to claim 14, and a functional unit, optionally a piece of furniture, according to claim 15. Advantageous embodiments of the invention are specified in further claims. The guide device comprises a guide carriage having a carriage body and a coupling device connected to the carriage body, a guide rail in which the guide carriage is displaceably mounted, and a connecting device having a rotatably mounted hinge element that can be connected to a partition element, for example an element of a folding door or folding sliding door, and that can be coupled to the guide carriage by the coupling device. According to the invention, it is provided that the connecting device comprises a hinge lever having a hinge lever end piece that is connected or connectable to the hinge element.and a hinge lever front piece that holds a coupling rod; - that the drive body has a carriage bearing and holds a lever shaft, - that the coupling device comprises a coupling lever having a coupling lever end piece that is rotatably held by the lever shaft, and at least one coupling lever front piece that has a locking part and a receiving part, which receiving part serves to receive and hold the coupling rod, - that the coupling device comprises a holding carriage that is displaceably held by the carriage bearing, which is connected to the drive body by at least one reset spring and which has at least one carriage front piece with a holding hook, - that the locking part has a locking contour and the holding hook has a holding contour, and - that the coupling lever is dimensioned such that upon rotation of the coupling lever into a locking position, the holding carriagethrough the interaction of the locking contour and the holding contour, and the coupling lever can be locked by the holding hook. The coupling lever can therefore be rotated between a receiving position, in which it preferably rests against a stop element, preferably on a part of the drive body, into a locking position and locked there by the holding carriage. The locking contour and the holding contour are designed such that the coupling lever end piece can displace the associated holding hook and, upon further rotation, can engage behind the holding hook, which is then pushed back by the at least one reset spring. By moving the holding carriage, the at least one coupling lever end piece can be released from the associated holding hook, and the coupling lever can be rotated back into the receiving position. By appropriately designing the locking contour and the holding contourIt can be provided that the coupling lever end piece can displace the locking hook upwards when the coupling lever is rotated HAWA 23-04 PCT / 26.04.24 under the application of force, in order to lock and release the coupling lever. For this purpose, the locking contour and the holding contour are preferably rounded or provided with corresponding flanks so that they allow the coupling lever to be rotated in both directions under the application of force. By applying pressure or tension to the coupling lever, the coupling lever end piece can be brought into a force-locking connection with the holding hook and released again from the force-locking connection with the holding hook. Direct access to the holding carriage is not necessary. However, if the locking contour and the holding contour can be interlocked in such a way that a blockage is created after the coupling lever end piece has engagedresults, the coupling lever is released by, for example, manually moving the holding carriage and releasing the holding hook from the coupling lever end piece. To connect a separating element, for example a door element, to the guide carriage, first the hinge part of the connecting device is connected to the separating element. Then, by lifting the separating element, the coupling rod of the connecting device is hooked into the receiving part of the coupling lever. After this process, the separating element is already held by the guide carriage, which is why a simple force applied to the separating element moves it against the guide carriage and the coupling lever is rotated into the locking position, in which the coupling rod is grasped and held by the holding hooks. The guide carriage can be designed to be slim by providing that the holding carriage rests directly against the carriage body and only the holding hooksexposed and accessible for the coupling lever. The retaining carriage therefore preferably protrudes only a few millimeters from the trolley body. The thickness of the coupling lever preferably corresponds to the dimensions of the retaining hook, so that the retaining carriage and the coupling lever rest directly against the trolley body in the closed position and take up hardly any space. In the locked position, the trolley body, the coupling lever and the retaining carriage practically form a unit, which differs only slightly from the dimensions of the trolley body. HAWA 23-04 PCT / 26.04.24 In a preferred embodiment, it is provided that the coupling lever comprises two spaced-apart lever arms, each with a coupling lever front piece, which has a locking part and a receiving part, and that the distance between the lever arms is greater than the width of the trolley body. The coupling lever therefore preferably has a U-profile, theSide arms are formed by the lever arms, which engage laterally around the carriage body preferably without play and can preferably each cooperate with a retaining hook of the holding carriage. The coupling lever and the holding carriage therefore preferably rest against the carriage body, at least in the locking position, without play, but can be rotated or displaced relative to it. A device part which executes complex movements and is held, for example, rotatably and displaceably, as well as corresponding expenditures for the complex mounting of this device part, are avoided. The holding carriage preferably has two spaced-apart carriage arms, each with a retaining hook, and thus preferably also a U-profile, which surrounds the carriage body on both sides, preferably tightly. In this preferred embodiment, the coupling lever and the holding carriage thus surround the carriage body on both sides fromdifferent directions but on the same sides of the carriage body, where they, or rather the locking contours and the holding contours, can interact. In the locking position, the coupling lever and the holding carriage form a unit by means of a force-locking connection, which partially encloses the carriage body and is held stably by it. The one-piece or two-piece coupling rod of the connecting device is held by the coupling lever in the locking position and is preferably aligned perpendicular to the hinge axis. To relieve the coupling lever in the locking position, the carriage body is preferably provided with at least one locking recess, into which the coupling rod can preferably be inserted in such a way that the load acting via the coupling rod does not act on the coupling lever, but on the carriage body. The locking recess is preferably provided with an input contour, via which the coupling rod enters theThe load acting via the coupling rod is therefore transferred from the coupling lever to the bogie body upon rotation of the coupling lever, so that the coupling lever is not loaded in the locked position and merely ensures that the coupling rod remains held in the locking recess. For this purpose, the coupling lever front piece is preferably fork-shaped, with the receiving part being limited on the one hand by the locking part and on the other hand by a holding part. When the coupling lever is rotated into the locked position, the held coupling rod can therefore be inserted into the locking recess and the holding carriage can be moved by a combination of the locking contour and the holding contour, and the coupling lever can be locked by the retaining hook. To ensure that the load of the coupling rod is actually taken over by the bogie body, the locking recess is preferably located somewhat higher than the receiving part of theCoupling lever. The coupling lever therefore transfers the coupling rod into the locking recess and is subsequently relieved of pressure. In a preferred embodiment, the carriage end piece is provided with at least one retaining element, which, after the retaining carriage has been inserted into the carriage bearing and after the lever shaft has been inserted, rests against the lever shaft and prevents the retaining carriage from becoming detached from the carriage bearing. The lever shaft therefore has a dual function, serving, on the one hand, to rotatably hold the coupling lever and, on the other hand, as a stop for the retaining carriage. In this way, the guide carriage can be manufactured particularly compactly and cost-effectively. In a further preferred embodiment, it is provided that the carriage body has a receiving chamber, into which the hinge lever front piece is preferably received in a form-fitting manner when the connecting device is coupled. In this embodiment, the hinge leverafter coupling to the guide carriage, it is held rigidly by the guide carriage. Alternatively or additionally, it is possible to fix the hinge lever front piece using screws and, if necessary, to adjust it and rotate it laterally as desired. In preferred embodiments, the carriage body comprises two locking recesses that serve to receive the coupling rod. For this purpose, the preferably provided receiving chamber has, for example, two side walls adjoining the carriage body, which are spaced from one another and in each of which one of the locking recesses is provided. HAWA 23-04 PCT / 26.04.24 The coupling rod, which is designed as a single or multi-part unit, protrudes from the hinge lever front piece with both end pieces and can be hooked into the coupling lever front piece of the coupling lever with both end pieces and each transferred into a locking recess in the carriage body. The carriage arms of the holding carriage are preferably provided with opposingSlide runners. The slide bearing is preferably designed as a guide profile, which has parallel guide grooves on both sides, into which the slide runners engage. The holding slide connected to the guide rail can therefore only be moved axially upwards or downwards, for example, against the lever shaft. The upward displacement occurs under the influence of the coupling lever. The downward displacement occurs under the influence of at least one reset spring, which can be designed as desired and is, for example, a return spring or a recoil spring. Preferably, two reset springs are provided, which are arranged on the front of the slide arms and are preferably each inserted into a receiving seat. The reset springs are preferably designed as helical springs. However, other springs, such as leaf springs or any tension springs, can also be used. In a further preferred embodimentIt is provided that the hinge lever front piece has a lever chamber in which the coupling rod is held by an adjusting device, preferably displaceable or adjustable parallel to the hinge shaft, so that the held separating element can be raised or lowered relative to the guide carriage. The adjusting device preferably comprises a threaded rod which is arranged in the lever chamber and rotatably mounted. The threaded rod is guided through a threaded bore in a bearing block which holds the coupling rod. By rotating the threaded rod, the bearing block with the coupling rod can be moved up and down. The threaded rod, which preferably has a bearing shoulder, preferably comprises on one end or at both ends a tool connection for a tool, by means of which the threaded rod can be rotated. The lever chamber preferably has a lower access opening and an upper access opening through whichthrough which a tool can be inserted and into the HAWA 23-04 PCT / 26.04.24 tool connection. If necessary, one of the access openings also serves to support the threaded rod. The coupling rod is designed in one or two parts and preferably protrudes on one side from a first chamber opening and on the other side from a second chamber opening of the lever chamber. The lever chamber has, for example, a larger chamber opening through which the adjusting device with the threaded rod, the bearing block and the coupling rod can be inserted into the lever chamber. For mounting in the guide rail, the guide carriage can be designed as desired and can be provided with any running elements and / or guide elements, in particular support rollers and / or guide rollers and / or stabilizing rollers or with corresponding sliding elements. The guide carriage preferably has at least one support roller and at least one guide roller.and / or at least one stabilizing roller. The guide device and the guide carriage can be connected to any single-part or multi-part partition elements, such as folding sliding doors. The guide device can also be installed in any functional units, such as pieces of furniture, cupboards and the like, which have a rotatable or displaceable or rotatable and displaceable single-part or multi-part partition element.
