Description

Technical Field

[0001] The present invention relates to a closing device for a sliding door device such as a sliding door device for a building or furniture, and a sliding door device.

Background Art

[0002] From the prior art, various closing devices are known, such as a closing device having a pulling rope and an elongated tension spring, whereby a sliding door can be automatically moved from a first end position to a second end position. Such a closing device usually has a complex structure. On the one hand, the pulling rope has to be guided around at least two cable pulleys, and on the other hand, the elongated tension spring has to be arranged accordingly. Typically, a part of the device is mounted in a housing, which involves a corresponding amount of labor.

[0003] A configuration having a sliding door that can be moved along a running rail by a drive unit is known, for example, from U.S. Patent No. 6,052,867, U.S. Patent No. 6,418,588, or U.S. Patent No. 9,341,019. U.S. Patent No. 6,052,867 discloses a sliding door having a glass plate that can be connected by a connector to a drive unit guided within a running rail. These connectors are inserted into openings in the glass plate and include mounting devices connected to the associated drive unit by threaded rods. U.S. Patent No. 6,418,588 discloses a sliding door having a wooden panel that can be connected to a drive unit by a connector. Each of these connectors includes a mounting portion mounted on the upper side of the sliding door and connected to the associated drive unit by a threaded rod. U.S. Patent No. 9,341,019 discloses a sliding door having a wooden panel that can be connected to a drive unit by a connector. These connectors include mounting devices mounted in mounting grooves on the upper side of the sliding door.

[0004] European Patent Application Publication No. 0417822 discloses a device having a sliding door that is displaceable in the vertical direction.

[0005] Canadian Patent Application Publication No. 2096671 discloses an automatic closing device having a housing, a pull rope, a tension spring in the form of a helical spring, a displaceable-held first roller set, and a fixedly-held second roller set. The displaceable-held first roller set is connected on one side to the tension spring and on the other side to a pull rope that is guided out of the housing by several loops around the two roller sets. The relative displacement of the two roller sets over a certain distance results in the pull rope being guided out of the housing by an extension length corresponding to twice the distance of the relative displacement of the roller sets multiplied by the number of loops. During this process, the tension spring, which is connected on one side to the slidably-held first roller set and on the other side to the housing via an adjustment device, is stretched by that distance. The tension spring and the two roller sets are arranged in a line in the axial direction, which is why the configuration takes up a relatively large amount of space and the extension length is relatively small. The extension length can be increased depending on the number of loops and by tension springs with smaller deflection and higher spring constants. With the addition of loops, the number of cable pulleys in the pulley set and their dimensions increase. Springs with higher spring constants also have larger dimensions and their behavior becomes less favorable. Overall, the dimensions of the locking device increase, which makes the installation of the locking device within the running rail questionable or requires an increase in the cross-sectional area of ​​the running rail.

[0006] European Patent Application Publication No. 3095351 discloses a closing device for a movable furniture part having a displaceable carriage in which a tension spring, a pull rope, and an actuation mechanism are provided. The tension spring can be locked in an extended position by the actuation mechanism and released after the carriage has been moved to the released position, and the furniture part is automatically pulled to the end position by the closing device. Therefore, this closing device is not suitable for guiding a sliding door over a longer distance from one end position to the other end position.

[0007] International Publication No. 2020 / 030385 discloses a closure device having a tension spring in the form of a coil spring and a pull rope guided by several loops around a displaceable first roller set and around a fixed second roller set, and further to the exit of the closure device. The tension spring and roller sets are also arranged in a single line in the axial direction, which again is why the closure device has to be relatively large so that the pull rope can be drawn out of the closure device for a longer distance. A further drawback is that a part of the device, in particular the fixed roller set, must be mounted inside the housing, which is a considerable cumbersome process.

[0008] This type of closing device also generates noise when the sliding door is moved, which is undesirable in single-story houses, commercial buildings, or hotels.

[0009] European Patent Application Publication No. 2090732 discloses a brake having a guide tube for a flap pivotably held by a furniture body, and therefore not for a device having a sliding door to be automatically guided from one door stopper to the other. The brake comprises a pull cable, one end of which is attached to the flap, guided only around a deflection wheel, and connected to a guide tube by the other end. The sliding part is a guide tube, which holds the deflection wheel and is slidably mounted on the guide tube connected to a spring cable. The spring cable is firmly held at a first end, guided around a sleeve, and connected to the sliding part by a second end. Thus, instead of two sets of pulleys, the device comprises only a single deflection wheel. Thus, the device enables braking of the rotation of the flap but does not enable driving of the sliding door. The sleeve around which the spring cable is guided is rotatably held by an axis inserted into a longitudinal slot in the guide tube. Therefore, the assembly of this device is relatively complex. Even the installation of the sleeve inside the guide tube requires skill. Furthermore, the spring cable must be inserted into the guide tube and guided around the sleeve, which may require special tools. Thus, the device of European Patent Application Publication No. 2090732 is unsuitable for driving sliding doors and, despite the small number of parts in the device, can only be assembled with considerable effort.

[0011] Accordingly, the present invention is based on the objective of providing an improved closing device for sliding door devices, and an improved sliding door device for buildings and furniture equipped with such a closing device.

[0012] Closure devices should be simple in design and easy to manufacture and assemble. Closure devices should be possible without connecting or mounting means, resulting in material savings and eliminating the need for installation work for connecting and mounting means such as screws.

[0013] Closing devices should be feasible to have reduced dimensions and improved characteristics. Despite their reduced dimensions, the pull rope should be able to be pulled out of the closing device over relatively large or increased extension lengths, allowing sliding doors such as wardrobe doors to move over greater distances and be automatically pulled back.

[0014] The tension spring should be selectable based on its physical properties, which optimize the characteristics of the closing device. The tension spring should have the smallest possible diameter so that the closing device can be designed to be as slim as possible.

[0015] The closing device should act strongly, yet have minimal wear and be silent.

[0016] A configuration having a sliding door that is automatically pulled to its starting position by a closing device when released should be installable in the same manner as before, given the small dimensions of the closing device, and should not require any special modifications. The closing device should be installable within a running rail having a reduced cross-sectional area.

[0017] Any sliding door device having an automatically driven sliding door should, advantageously, be achievable by using a closing device. The sliding door configuration should allow the sliding door to move automatically over a wide range from one end stopper to the other end stopper, and in particular between open or closed end positions in one or the other direction. Noise and abrupt stops should be avoided. [Means for solving the problem]

[0018] This problem is solved by the closing device described in claim 1, and the sliding door device described in claim 13, which comprises at least one such closing device. Advantageous embodiments of the present invention are specified in further claims.

[0019] A closing device provided for a sliding door device having at least one sliding door comprises a device body, a first roller set displaceably held, a second roller set fixedly held by the device body, a tension spring directly or indirectly connected to the first roller set by a first spring end and directly or indirectly connected to the second roller set by a second spring end, and a pull rope guided around the first and second roller sets by several loops, directly or indirectly connected to the first roller set or the device body by a first rope end, and led out of the closing device by a second rope end.

[0020] The first roller set has several first cable pulleys, and the first cable pulleys are preferably held by a first mounting shaft so as to lie horizontally with respect to each other and be coaxially aligned with respect to each other. The second roller set has several second cable pulleys, and the second cable pulleys are preferably held by a second mounting shaft so as to lie horizontally with respect to each other and be coaxially aligned with respect to each other.

[0021] Each of the cable pulleys preferably has a peripheral groove in which a towing rope is partially received and guided.

[0022] Preferably, the cable pulleys can rotate independently of each other. Accordingly, the cable pulleys are preferably individually mounted, preferably by means of high-quality plain bearings or ball bearings. The use of high-quality bearings, especially ball bearings, significantly eliminates signs of friction loss and wear. Accordingly, the towing rope can always be pulled out of the closing device by the same tension even after a long period of operation. Preferably, self-lubricating plain bearings or self-lubricating ball bearings are used so that the closing device operates without maintenance.

[0023] According to the present invention, the device body comprises a holding rail for displaceably holding a roller carriage comprising a carriage body, the roller carriage is coupled to a first spring end and comprises a first mounting shaft by which a first roller set is rotatably supported, the device body is integrally force-fittingly or form-fittingly connected to a connecting device connected or connectable to a drive body of a drive unit, the connecting device rotatably holds a deflection pulley around which a tension spring is guided by means of a bearing shaft.

[0024] In the relaxed state, the tension spring may extend along the entire length of the closing device on one side of the deflection pulley, and on the other side of the deflection pulley, it may extend to a length at least approximately corresponding to the entire length of the closing device. Thus, the physical properties of the tension spring can be selected almost arbitrarily, and the closing device can be freely designed to have advantageous working motion. If a lower spring constant is present, the tension spring can be realized in smaller dimensions, particularly in a smaller diameter, which is why the closing device can be realized in a smaller width.

[0025] If the tension springs were guided around the deflection pulley so that their ends lay overlapping each other in a vertical direction, this would not result in expansion of the closing device. Since the diameter of the tension springs is smaller, the width of the closing device is not determined by the tension springs. Therefore, the closing device can preferably be realized with a reduced width such that the drive unit can be inserted into the sliding door, typically from below, through a longitudinal slot in the running rail through which the drive unit is connected to the sliding door. Alternatively, the closing device is connected to the associated drive unit and inserted into the end face of the running rail at the end of the rail.

[0026] By extending the deflection, the dimensions of the closing device can also be significantly reduced in the axial direction parallel to the running rail, while still leaving a long working path that allows the sliding door, away from the door opening, to be pulled in front of the door opening, enabling the door opening to be fully opened or closed.

[0027] Preferably, the tension springs are guided around the deflection pulley so that their ends are aligned parallel to each other and point in the same direction.

[0028] Since the tension spring can be stretched over the entire length of the closing device, the first roller set can also be moved over this length, which is why longer working paths, i.e., larger door openings and wider doors, can be operated even if the dimensions of the closing device are small.

[0029] Tension springs are preferably helical and / or preferably essentially polygonal or cylindrical. Preferably, tension springs are made of metal, plastic, or rubber, or a combination thereof, for example, a combination of rubber and plastic. Tension springs are preferably made of rubber, especially soft rubber, latex, natural rubber, or elastomer. Preferably, the tension spring or the core of the tension spring is formed of a plurality of bundled rubber threads, especially a plurality of bundled soft rubber, latex, natural rubber, or elastomer threads.

[0030] Preferably, the tension spring, which forms the core of the spring and is made of metal and / or rubber and / or plastic, is enclosed by a sheath. The sheath is manufactured so that the elongation properties, particularly the spring constant, do not change, or change only as desired. Thus, the sheath may contribute to the flexibility of the tension spring, or it may act only as a protective element that protects the tension spring from external influences, particularly increased wear.

[0031] The outer casing is firmly or loosely connected to the spring core, which is made of metal and / or rubber and / or plastic, and preferably has good inward and / or outward sliding properties.

[0032] Preferably, and especially if the sheathing is firmly connected to the core of the spring, the sheathing is a stretchable covering or a stretchable mesh.

[0033] The exterior is preferably made of rubber or plastic, or woven from multiple threads made of rubber or plastic. The threads are, for example, made of polypropylene or polyester.

[0034] The casing protects the enclosed spring core from external influences, and at the same time, protects the deflection pulley from undesirable influences from the tension spring, for example, if the tension spring is a metal coil spring. For example, the casing prevents the tension spring coil, which is stretched when in contact with the deflection pulley, from mechanically compressing the deflection pulley and damaging it over a longer period of time.

[0035] Tension springs made of rubber or elastomer possess high flexibility and high tensile strength, do not corrode, and operate virtually silently.

[0036] The device body of a closure device that holds a roller carriage by a first roller set, a second roller set, and a deflection pulley may have an integrated or modular design. In the case of a modular design with at least two modules, the device body can be manufactured particularly easily.

[0037] In a preferred embodiment, The device body comprises a connector that is connectable to the first end of the retaining rail and forms a structural element of the connecting device, and / or The device body comprises a terminal body which is connectable to a second end of a holding rail and includes a second mounting shaft on which a second roller set is rotatably held.

[0038] Therefore, together with the connectors and / or terminals, the retaining rail forms a modular device body that holds the moving portion of the closing device. The connectors or terminals may be connected integrally with the retaining rail. However, preferably, the connectors and terminals may be connected to and detached from the retaining rail.

[0039] Preferably, the connectors and terminations can be pressed into form fittings within the retaining rail and held therewithout or at least substantially without play with respect to the longitudinal axis of the retaining rail. Thus, the connectors and terminations can be easily secured by applying force in the direction of the retaining rail.

[0040] In a preferred embodiment, the retaining rail has one or more guide tracks on which a roller carriage is mounted so as to be displaceable along it. In a preferred embodiment, these guide tracks are also used to mount connectors and / or terminations.

[0041] Preferably, the retaining rail comprises two corresponding guide tracks on the outside and / or inside, which ensure that the roller carriage and the connector and / or terminal are held on both sides.

[0042] To connect with the guide track, the carriage body has one or more guide elements, each of which is held by the associated guide track.

[0043] The connector has one or more first support elements, each of which is held by an associated guide track.

[0044] The terminal has one or more second support elements, each of which is held by an associated guide track.

[0045] The guide elements of the roller carriage and the first support elements of the connector and the second support elements of the terminal are preferably designed as runners, cams, grooves, or rollers so that they can be held in the form fitting by complementary guide tracks, such as grooves, channels, or ribs. Preferably, at least the guide elements of the roller carriage are designed as rollers that can travel without friction within the associated guide track.

[0046] In a preferred embodiment, the connecting device is pulled by a tension spring toward a first end of the retaining rail and held by a connector at the first end of the retaining rail, and / or the terminal is pulled by a tension spring toward a second end of the retaining rail and held at the second end of the retaining rail. Both the connecting device and the terminal, which include the connector, are connected to a tension spring, and the tension spring is preferably kept continuously extended, so that the tension spring is used to connect the connecting device to the connector on one side and the support device to the retaining rail on the other. When installing the closing device, the first end of the tension spring is connected to the roller carriage before being inserted into the retaining rail. Thus, the connector and the terminal are secured by connecting the second spring end to a second coupling device connected to the terminal. Accordingly, the connecting device is pulled by a tension spring toward the first end of the retaining rail and held at the first end of the retaining rail by the connecting body, and / or the end body is pulled by a tension spring toward the second end of the retaining rail and held at the second end of the retaining rail.

[0047] In a further preferred embodiment, The first spring end is a first coupling portion which is an integral part of the first spring end or is connected to the first spring end, and comprises a first coupling portion connected to a first coupling device which is fixedly or slidably connected to a first roller set, and / or The second spring end portion is a second coupling portion which is either an integral part of the second spring end portion or connected to the second spring end portion, and comprises a second coupling portion connected to a second coupling device which is fixedly or slidably connected to the device body.

[0048] The first coupling device and / or the second coupling device are preferably designed as tension devices and may be displaceably mounted, for example, and optionally positioned along a raised area, for example by an adjustment screw, to set a desired spring preload.

[0049] The first coupling device and / or the second coupling device may also comprise several latching elements arranged in a row, the associated spring ends of which can be optionally hooked into the latching elements.

[0050] Preferably, the tension spring is pre-stretched by selecting a distance shorter than the distance between the coupling devices. Thus, the tension spring can be stretched to this distance during assembly and can be pre-stretched.

[0051] Alternatively, the first and / or second coupling portion may also be adjustable. For example, the first and / or second coupling portion may be rotatably connected to the associated spring end and have external threads, thereby allowing the first and / or second coupling portion to be screwed into threads present, for example, on the device body or a part of the device connected to the device body. To actuate the first or second coupling portion, an engaging element is preferably provided which can be reliably connected to a tool that can be operated manually.

[0052] The device body comprises at least a retaining rail, from which a roller carriage having a carriage body is displaceably held, the carriage body is coupled to a first spring end, and comprises a mounting shaft from which a first roller set is rotatably held. The retaining rail and the roller carriage that can move along the retaining rail provide a stable structure for the closing device. Furthermore, this provides a smooth and controlled movement sequence when the closing device is actuated. Advantages also exist when assembling the closing device, particularly during insertion or insertion of the pull rope. The controlled guidance of the sliding cable pulley prevents lateral movement that could generate noise.

[0053] The device body may be made of metal or plastic. The carriage body may also be made of metal or plastic. The pull rope may also be made of metal or plastic, and preferably has a braided structure of threads made of metal and / or plastic.

[0054] The retaining rail preferably comprises an upper portion along which a roller carriage can be displaced, and a lower portion. The deflection pulley is preferably held at one end of the retaining rail by a bearing shaft, the bearing shaft is preferably held on both sides by bearings, the bearings are connected to or integrated with the device body.

[0055] The first spring end is preferably guided from the deflection pulley to the roller carriage on the upper side of the retaining rail. The second spring end is preferably guided from the deflection pulley to the second coupling device on the lower side of the retaining rail, the second coupling device being fixed to or slidably connected to the device body.

[0056] The carriage body is preferably connected to the first coupling device in a fixed or movable manner, and optionally integrally.

[0057] Preferably, the carriage body comprises at least one guide element in the form of a sliding runner, the at least one guide element being securely held by a retaining rail. Preferably, the carriage body has two spaced sliding runners, which are form-fitted to the guide track on both sides. The guide track is designed, for example, as a retaining channel. One or more carriage runners can also be securely engaged with one or more retaining channels in the retaining rail. For example, the retaining rail may have retaining channels having inclined flanks corresponding to inclined flanks of the carriage body. Thus, the carriage body can also be advantageously inserted into the retaining channels.

[0058] Preferably, the retaining rail has a track entrance into which one or more carriage runners can be inserted. The track entrance can preferably be closed by locking screws so that the roller carriage can no longer detach from the retaining rail on its own.

[0059] The retaining rail may also include a mounting grid into which stopper elements can be inserted as desired to restrict the movement of the roller carriage.

[0060] Retaining rails can be designed in different ways. For example, The retaining rail is plate-shaped and has an upper and a lower portion. The first spring end is guided from the deflection pulley to the roller carriage at the upper portion of the retaining rail, and the second spring end is guided from the deflection pulley to the second coupling device at the lower portion of the retaining rail, or The retaining rail is formed in the shape of a C-shaped or U-shaped contour and has two side walls connected to each other by a central portion, with one of the guide tracks provided in each case on the inner side of the side walls facing each other, the first spring end being guided from the deflection pulley to the roller carriage within the retaining rail, and the second spring end being guided from the deflection pulley to the second coupling device on the lower side of the retaining rail.

[0061] The retaining rail preferably has the same cross-section along its entire length and can be easily manufactured using a forming process, for example, by compression molding or other extrusion methods. As a result, the retaining rail can be cut to any length.

[0062] Preferably, a damping device is provided within the closing device, and the damping device connects the carriage body and the device body such that the damping device counteracts the return of the roller carriage. The damping device includes, for example, a damping cylinder and a damping piston moved by a push rod within the damping cylinder.

[0063] The damping cylinder is inserted into the device body, for example, while the push rod is connected to or may be connected to the roller carriage. If the push rod is firmly or permanently connected to the roller carriage, or to the carriage body, damping occurs over the total distance the roller carriage travels, and therefore over the total distance the sliding door travels during automatic displacement. However, it is usually sufficient for the sliding door and / or roller carriage to be damped before they reach their end positions in their movement, and elements of the damping device, such as the push rod or damping cylinder, are made available for this purpose. For example, pneumatic or hydraulic damping devices or hydraulic damping devices may be used as damping devices.

[0064] The carriage body of a roller carriage can be connected to the associated drive unit in different ways. Preferably, the carriage body is provided integrally with the connecting device in a force fitting or form fitting, and the connecting device is connected or can be connected to the drive body of the drive unit in a form-fitting and / or force-fitting manner, or integrally, and the drive body of the drive unit is displaceable within the running rail.

[0065] The device body is preferably connected to a support wheel at an end away from the connected drive unit, and the support wheel rotates on the running rail, holding and stabilizing the rail device in a selected orientation.

[0066] The first end of the pull rope can be connected to the device body or roller carriage in any way. Preferably, the first end of the rope can be optionally connected to a roller carriage to a displaceable first roller set, and the pull rope can also be pulled out of the closing device by the displacement of the displaceable first roller set or roller carriage.

[0067] For example, the first rope end may be connected to the carriage body or device body by a screw, or coupled to a suspension device. For this purpose, the first rope end preferably comprises a connecting eyelet, connecting loop, or connecting ring. Thus, the first rope end may be advantageously hooked onto, for example, a hook. The first rope end may also be inserted into a clamp, which is then tightened.

[0068] The second rope end, led out of the closing device, can be connected in the same or different manner to, for example, a running rail or a device connected to the running rail, particularly a holding device or a buffer device.

[0069] In a preferred embodiment, the pull rope having a second rope end is guided out of the closing device through an exit opening, thereby a fixed second roller set is preferably located in the area of ​​the exit opening, and a displaceable first roller set is located away from the exit opening and can be displaced toward the exit opening. This ensures that the pull rope of the maximum length can be guided out of the closing device. Deflection pulleys are preferably located at the end of the closing device opposite the exit opening.

[0070] The closing device of the present invention can be used to automatically move a sliding door to an end position in any configuration having a sliding door, such as a sliding door system or, in particular, furniture such as a cabinet.

[0071] The sliding door is used, for example, to close a room opening or a wardrobe opening, and is connected at the upper part to a first drive unit and a second drive unit, the first and second drive units being slidably mounted within a running rail. Preferably, one of the drive units is connected to the closing device so that the closing device is held between the two drive units. The closing device of the present invention may be used in a sliding door configuration having a sliding door made of wood or glass, for example, as disclosed in U.S. Patent No. 6,052,867, U.S. Patent No. 6,418,588 or U.S. Patent No. 9,341,019, as previously mentioned. The connecting device described therein allows for adjustment of the height of the sliding door.

[0072] The sliding door may be moved away from the opening and may be held in an end position, preferably in a releasable manner, by a retaining device, and may be released again by applying force. The retaining device may be of any design and may have any latching element, such as at least one magnet or at least one retaining clip or hook.

[0073] The running rail extends from a first rail end to a second rail end. Preferably, a first retaining device having a latching element is located at least at the first rail end, thereby releasably locking the sliding door in a position where the tension spring is extended. In this case, the second rope end of the pull rope is preferably connected directly or indirectly to the second rail end.

[0074] The present invention will be described in more detail below with reference to the drawings. [Brief explanation of the drawing]

[Figure 7] Figure 1 shows a closing device 1 of the present invention in a further preferred embodiment, the closing device 1 comprising a modular device body 10 having a retaining rail 101 in which, on one side, a connecting body 102 of a connecting device 18 is inserted and on the other side, a terminal body 103 for holding a second roller set 12 is inserted; and a mounted tension spring 15 for pulling and securing the connecting body 102 and the terminal body 103 to the retaining rail 101. [Figure 8] Figure 7 shows the closing device 1 during assembly, which is performed in a few simple steps. [Figure 9a] This is a diagram of a connecting device 18 having a connecting body 102 and a deflection pulley 19 separated from the connecting body 102. [Figure 9b] Figure 9a shows the connector 18 from the other side, the connector 18 having a coupling element 181, and the closing device 1 can be connected to the drive unit 2A according to Figure 1 through the coupling element 181. [Figure 9c] This figure shows an end unit 103 that supports a second roller set 12 and preferably holds a support wheel 199 that can rotate within the running rail 8 of Figure 1. [Modes for carrying out the invention]

[0076] Figure 1 illustrates a sliding door device 100 of the present invention having a sliding door 5. The sliding door 5 is connected at the top to a first drive unit 2A and a second drive unit 2B that are displaceably mounted within a running rail 8. The running rail 8, partially shown by dotted lines, extends over a length that allows the door opening or room opening to be fully opened or closed. The running rail 8 comprises a first rail end 81 in which a first retaining device 9A is preferably disposed, and a second rail end 82 in which a second retaining device 9B is preferably disposed. The two retaining devices 9A, 9B are positioned so that they can cooperate with the associated drive units 2A or 2B at the open and closed end positions of the sliding door 5, preferably so that the drive units 2A or 2B can be braked by at least one damping device 91, and / or, preferably so that the drive units 2A or 2B can be held in a force-locking, releaseable manner by at least one latch element 92.

[0077] The drive units 2A and 2B are connected to the sliding door by mounting rails 3A and 3B, which are held in mounting grooves 50 on the upper part of the sliding door 5. However, the drive units 2A and 2B may be connected to the sliding door 5 in any other way as described above with reference to the prior art.

[0078] On the side facing the second drive unit 2B, the first drive unit 2A is connected to a closing device 1, which allows the sliding door 5 to always move automatically in the closing direction toward an optionally provided second retaining device 9B. When the sliding door 5 reaches the second retaining device 9B or the end position in the closed position, the second drive unit 2B is held in place by the latch element 92 of the second retaining device 9B in a force-locking but releaseable manner. Alternatively, the sliding door 5 may be held in this end position by the closing device 1. The dotted line indicates that the closing device 1 comprises a pull rope 13, which is connected to the second retaining device 9B or the second rail end 82 of the running rail 8. When the sliding door 5 is opened, the pull rope 13 is pulled out of the closing device 1, and a tension spring 15 connected to it is extended.

[0079] The sliding door 5 can be grasped by hand at the handle 51, released from the second retaining device 9B, and pulled to the right toward the first retaining device 9A. During this process, the tension spring in the closing device 1 is stretched. At the end position, after the sliding door 5 has been opened, the first drive unit 2A is held in a force-locking but releaseable manner by the latch element 92 of the first retaining device 9A. The tension spring 15 of the closing device 1 is loaded at this position and can automatically move the sliding door 5 back to the closed position to the left after it has been manually released from the first retaining device 9A. During this process, the pull rope 13 is pulled back into the closing device 1.

[0080] The retaining devices 9A and 9B can also be implemented in other ways, for example, by magnets or locking devices provided inside or outside the running rail 8. In a preferred embodiment, the locking device is provided within the closing device 1, which is actuated by an actuation element when it reaches the end position.

[0081] The closing device 1, which has an extended tension spring 15, is operated by the user, for example, by pulling a handle 51 or by activating an electromechanical element.

[0082] Figure 2a illustrates the upper portion of the sliding door device 100 of Figure 1, which includes a closing device 1, two retaining devices 9A and 9B, and two drive units 2A and 2B fixed to the upper edge of the sliding door 5 by mounting rails 3A and 3B in mounting grooves 50. The sliding door 5 or wooden panel having the mounting grooves 50 may be connected to the drive units 2A and 2B by a connecting device, for example, as disclosed in U.S. Patent No. 9,341,019.

[0083] Each of the two drive units 2A and 2B has a drive body 20, which holds two rollers or a pair of rollers 29 and is connected to a mounting block 22 by a threaded rod 21, which is slidably held and fixed within the associated mounting rails 3A and 3B.

[0084] Each of the two holding devices 9A and 9B has a holding body 90 and a latching element 92, the latching element 92 forming a flexible, curved holding arm that, as soon as it reaches its end position, engages with and holds onto the opposing rollers 29 of the opposing drive unit 2A or 2B. Alternatively, the latching element 92 may cooperate with the drive body 20.

[0085] The closing device 1, from which the pull rope 13 is guided to the second holding device 9B, comprises a device body 10, which optionally holds a support wheel 199 at the front and comprises a force-locking, form-locking, or integrated connecting device 18 at the rear, and the closing device 1 is connected to the drive body 20 of the first drive unit 2A by the connecting device 18.

[0086] Figure 2b illustrates the second retaining device 9B, the closing device 1, the two drive units 2A and 2B, and the associated mounting rails 3A and 3B without the running rail 8. The mounting body 22 is held within the mounting rails 3A and 3B, which are secured by locking screws 221 and connected to the drive bodies 20 of the associated drive units 2A and 2B by connecting parts, threaded rods, or connecting screws 21.

[0087] Figure 3 illustrates the closing device 1 of Figure 1 in a preferred embodiment. The closing device 1 comprises a device body 10, a displaceable first roller set 11 having four coaxially aligned first cable pulleys 111, 112, 113, 114 held by a first mounting shaft 110, a second roller set 12 having three coaxially aligned second cable pulleys 121, 122, 123 held by a second mounting shaft 120, and a deflection pulley 19 (symbolically shown) guided around and connected to the first roller set 11 by a first spring end 151. The device comprises a tension spring 15 connected to the device body 10 by a second spring end 152, and a pull rope 13 guided around the first cable pulleys 111, 112, 113, 114 of the first roller set 11 and around the second cable pulleys 121, 122, 123 of the second roller set 12, and directly or indirectly connected to the first roller set 11 or the device body 10 by a first rope end 131, and guided outside the device body 10 through an exit opening 106 by a second rope end 132.

[0088] The device body 10 may have a single-part or multi-part structure and may be made of metal and / or plastic. The portion of the device body 10 with the retaining rails 101 may be advantageously manufactured from plastic or metal by an extrusion process. The closing device is covered or closed by the side walls 108, and possibly by a casing or cover, with foam locking. The retaining rails 101 are plate-shaped and have guide tracks 1011 on each side.

[0089] The device body 10 has a connecting device 18 at its rear end, which is connected to, or integrally connected to, a form fitting and / or force fitting on the drive body 20 of the associated drive unit 2A. The connecting device 18 is integrally connected to the device body 10, or is connectable to the device body 10 via a force fitting and / or form fitting, and is optionally screwable. At its front end, the device body 10 has a bearing 109, which holds the wheel shaft 1990, and an optionally provided support wheel 199 is rotatably mounted on the wheel shaft 1990. At its front end, the device body 10 holds a second mounting shaft 120 and a fixed second roller set 12.

[0090] The tension spring 15 is preferably made of rubber, plastic or metal, or of a braid of rubber, plastic or metal, and preferably comprises an outer sheath 155, for example, a braid of plastic threads (see Figure 5a). Preferred materials for manufacturing the tension spring 15 and the outer sheath 155 are described above.

[0091] In this preferred embodiment, the device body 10 comprises a retaining rail 101 from which a roller carriage 14 is displaceably held. The roller carriage 14 has a carriage body 140 from which a first mounting shaft 110 and a first roller set 11 are held. The carriage body 140 also holds or comprises a first coupling device 142, which holds a first spring end 151 to a form fitting and / or force fitting. On the lower side, the carriage body 140 has guide elements 141 in the form of lubricant on both sides, which surround the guide track 1011 of the retaining rail 101, which has at least a substantially T-shaped contour, to the form fitting. The roller carriage 14 with the first roller set 11 can move along almost the entire length of the rail body 101 to a fixed second roller set 12.

[0092] The retaining rail 101 has a track entrance 1010, which allows a roller carriage 14 or guide element or lubricant 141 to be form-fitted to the retaining rail 101. The track entrance 1010 is closed by a locking screw 1019 so that the roller carriage 14 cannot automatically detach from the retaining rail 101.

[0093] When the sliding door 5 is opened, the pull rope 13 is pulled out of the closing device 1, causing the roller carriage 14, which has the first roller set 11, to be pulled against the second roller set 12. During this movement, the length of the loop surrounding the two roller sets 11, 12 is shortened, which is why the pull rope 13 is released by a corresponding amount. At the same time, the tension spring 15 is pulled around the deflection pulley 19, stretched to its maximum length, and stores energy, which is released as soon as the sliding door 5 is released from its end position. The roller carriage 14 is pulled back to the other end position by the tension spring 15, thereby reinserting the pull rope 13 into the closing device 1, and the sliding door 5 is automatically moved back to the closed position.

[0094] Figure 3 also illustrates an example of the first rope end 131, which is guided into a threaded hole 107 in the device body 10 or a threaded hole 147 in the carriage body 140 and secured thereby by a mounting screw 7. Figure 6 illustrates that the device body 10 or the carriage body 140 may be attached by cable connection devices 105 or 145 of different designs, to which the first rope end 131 may be hooked, for example. The cable connection devices 105 or 145 may be, for example, hooks, clips or clamps. Preferably, the first rope end 131 is connected to the roller carriage 14 so that the pull rope 13 can also be pulled out of the closing device 1 by the same amount as the displacement of the roller carriage 14.

[0095] Figure 4a illustrates a portion of the closing device 1 of Figure 3, which has a tension spring 15 guided around the deflection pulley 19 and connected by a first spring end 151 to a first coupling device 142 of the roller carriage 14. The spring ends 151 and 152 are shown to have coupling portions 1510 and 1520, which can be connected in form fittings to the first coupling device 142 of the coupling carriage 14 and the second coupling device 16 of the device body 10, respectively (see Figure 5a).

[0096] Figure 4b illustrates a portion of the closing device 1 of Figure 4a, which has a displaced roller carriage 14 relative to a fixed second roller set 12. The tension spring 15 is partially stretched, and the pull rope 13 is partially pulled out of the closing device 1.

[0097] Larger and smaller double-headed arrows symbolize optional damping devices 17, which dampen the movement of the roller carriage 14 as it is returned. Longer double-headed arrows symbolize that the movement of the roller carriage 14 can be damped over the entire return path. Smaller double-headed arrows symbolize that the movement of the roller carriage 14 can be damped even in only a portion of the return path. A damping device 17 removed from one of the retaining devices 9A, 9B is also shown, which has a damping cylinder 171 and a push rod 172, thereby allowing a damping piston to be displaced within the damping cylinder 171. The damping piston is intended to be surrounded, for example, by a layer of oil or to displace air from the damping cylinder 171. Typically, this type of damping device 17 includes a return spring, which, for example, returns the damping piston to its starting position and pushes the push rod 172 outward. For example, as illustrated in Figure 2a for the holding devices 9A and 9B, the damping device 17 is inserted into a hole in the device body 10 or carriage body 140, and preferably a push rod 172 or damping cylinder 171 having a flexible element at its front is aligned with the roller carriage 14 or a portion of the device body 10, and can cooperate with the latter before the sliding door 5 or roller carriage 14 reaches its end position.

[0098] Figure 5a illustrates the device body 10 of the closing device 1 of Figure 3, which comprises a deflection pulley 19, a roller carriage 14, and a tension spring 15 released from the device body 10 and the roller carriage 14. In this configuration, the optional support wheel 199 is removed. As a result, a second coupling device 16 is visible, which allows the coupling portion 1520 of the second spring end portion 152 to be hooked therein. In a preferred embodiment, the second coupling device 16 is adjustable by an adjustment screw 161 and can be displaced parallel to the retaining rail 101, which has an upper portion 101T and a lower portion 101B.

[0099] After assembly, the tension spring 15 is guided around the deflection pulley 19 such that the first spring end 151 extends along the upper part 101T of the retaining rail 101 and the second spring end 152 extends along the lower part 101B of the retaining rail 101. The two spring ends 151 and 152 are preferably aligned parallel to each other. The first spring end 151 is connected to the first coupling device 142 of the roller carriage 14 by the first coupling portion 1510. The second spring end 152 is connected to the second coupling portion 1520 by the second coupling device 16, which is preferably adjustable. The tension spring 15 is preferably made of rubber and preferably has an outer covering 155, which preferably consists of a braid of rubber fibers or plastic fibers.

[0100] Figure 5b illustrates the device body 10 and the separated roller carriage 14 of Figure 5a, the roller carriage 14 having a first coupling device 142 which is rotated 180°, and the first coupling device 142 is provided for form-locking coupling of the first end portion 151 of the tension spring 15.

[0101] Figure 6 illustrates the closing device 1 of Figure 3, which has a device body 10 and a connecting device 18, the connecting device 18 being connected or connectable to the drive body 20 of the associated drive unit 2A by form fitting and / or force fitting, or integrally.

[0102] Figure 7 illustrates a closing device 1 of the present invention having a modular device body 10 in a further preferred embodiment, the modular device body 10 comprising a retaining rail 101, a connector 102 forming the device body of a connecting device 18, and a terminal 103 holding a second roller set 12. The connector 102 is inserted on one side of the retaining rail 101, and the terminal 103 is inserted on the other side of the retaining rail 101 and is held detachably. The connector 102 and / or terminal 103 are displaceable in form fittings within the retaining rail 101 and are preferably held without play perpendicular to the longitudinal axis x of the closing device 1. Thus the retaining rail 101, the connector 102 and / or terminal 103 are connected to each other in form fittings, thus forming the device body 10.

[0103] The tension spring 15 is connected by a first spring end 151 to a first coupling device 142 of the roller carriage 14, and by a second spring end 152 to a second coupling device 16, which is preferably an integral part of the terminal body 103.

[0104] The tension spring 15 is stretched, pulling the connector 102 and the terminal 103 against the holding rail 101, and therefore against each other. Thus, the device body 10, consisting of the holding rail 101, the connector 102, and the terminal 103, is held together by the tension spring alone.

[0105] A retaining rail 101, preferably symmetrically designed and shown in a longitudinal cross-section along the longitudinal axis x, preferably has a downwardly opening U-shaped or C-shaped contour with a central portion 101X, the central portion 101X adjoins the side wall portions 101Y on both sides. A guide track 1011, for example, a retaining channel or retaining groove, is positioned inside the side wall portion 101Y, and within the guide track 1011, the guide element 141 of the roller carriage 14, the first support element 1021 of the connector 102, and the second support element 1031 of the terminal 103 engage in a form-fitting manner. The guide element 141, the first support element 1021, and the second support element 1031 are preferably of the same design. However, the guide element 141 may be designed as a roller or may be made of a material such as POM having high sliding ability. In the illustrated embodiment, the carriage body 140 comprises two cylindrical guide elements 141, the connector 102 comprises two cylindrical first support elements 1021, and the terminal body 103 comprises two cylindrical retaining elements 1031, which are spaced apart from each other and each protrudes into the associated channel-shaped guide track 1011 at the side wall portion 101Y of the retaining rail 101. Figure 7 also illustrates that the connector 102 has a connecting plate 1022 and the terminal body 103 has a terminal plate 1032, which allow the retaining rail 101 to be terminated on both sides. Furthermore, a pull rope 13, preferably mounted as in the closing device 1 of Figure 3, is schematically illustrated. In the embodiment of the closing device 1 of Figure 7, compared to the embodiment of Figure 5, the retaining rail 101 is closed on three sides, so a cover is not required.

[0106] Figure 8 illustrates the closing device 1 of Figure 7 during assembly. The retaining rail 101 is shown in a shortened form. Arrows indicate that the roller carriage 14, the connecting device 18 with the connector 102, and the terminal 103 can be inserted into the retaining rail 101 in the same manner. The pull rope 13, not shown, is already attached and can be inserted into the retaining rail 101 through the lower opening.

[0107] The tension spring 15 is already connected to the roller carriage 14 through the connecting device 18, and the closing device 1 can be assembled in a few simple steps. After inserting the roller carriage 14, the connecting device 18, and the terminal 103, the second end portion 152 of the tension spring 15 protrudes downward and only needs to be extended and connected to the second coupling device 16. Once the tension spring 15 is installed, the assembly of the closing device 1 is complete.

[0108] Figure 9a illustrates a connecting device 18 having a connecting body 102 and a deflection pulley 19 having a bearing shaft 190 and separated from the connecting body 102. The connecting body 102 is fork-shaped and has two legs, and the deflection pulley 19 can be mounted between the legs by the bearing shaft 190.

[0109] Figure 9b illustrates the connector 18 from the other side of Figure 9a, which has a coupling element 181, and the closing device 1 can be connected to the drive unit 2A according to Figure 1 through the coupling element 181.

[0110] Figure 9c illustrates an end unit 103 that supports a second roller set 12 and preferably holds a support wheel 199 that can rotate within the running rail 8 of Figure 1. [Explanation of Symbols]
