AI Technical Summary
Conventional guide systems for movable cover elements, such as sliding doors and windows, face issues with tilting moments when in an open position, as existing compensation devices obstruct the opening and cannot be used effectively, rendering the window or door unusable.
A guide system incorporating a rope connecting guide bodies with a deflection device that allows the rope to be guided at a right angle between guide rails, and a shortening mechanism to adjust rope length based on the cover element's position, ensuring adequate compensation for tilting moments while keeping the opening free.
The solution effectively compensates for tilting moments across all positions of the cover element, maintaining the usability of the window or door by keeping the rope outside the opening area and adjusting its length to match the increasing tilting moment as the cover element opens.

Description
[0001] Guide system for the movable storage of at least one
[0002] Cover element
[0003] The invention relates to a guide system for the movable mounting of at least one cover element for covering an opening in a fixed structure, comprising: a first guide rail and a first guide body displaceably arranged thereon, a second guide rail and a second guide body displaceably arranged thereon, and a compensation device for compensating a tilting moment of a cover element, wherein the cover element is movable by the guide system between a first position, preferably a closed or intermediate position, and a second position, preferably an open position, and an arrangement with at least one such guide system.
[0004] Such guide systems are already known from the state of the art and are used, for example, for the guidance of (furniture) doors or folding-sliding doors.
[0005] A compensation device is necessary in guide systems in which one end of the cover element floats freely (in other words is not guided) when the cover element is in the open state, in order to prevent a tipping moment of the cover element and thus a lowering of the cover element.
[0006] In the prior art, pivoting lever mechanisms or cable pull devices are usually used for this purpose. With conventional sliding doors or, in particular, sliding windows, where the opening is located directly behind the cover element in a closed or intermediate position, compensation devices according to the prior art cannot be used. Compensation devices according to the prior art extend into a region of the opening when the cover element is in the open position in order to provide sufficient support for the cover element.
[0007] This would mean that a window or door would no longer be usable, as the compensation device would at least partially block the window or door.
[0008] The object of the invention is to at least partially eliminate the disadvantages described above and to provide a guide system which is improved compared to the prior art and an improved arrangement with such a guide system.
[0009] This object is achieved by the features of independent claims 1 and 17 .
[0010] According to the invention, it is therefore provided that the compensation device has at least one cable, wherein the at least one cable connects the first guide body and the second guide body to one another, and that a deflection device is provided, by means of which the at least one cable can be guided at least in some areas, preferably in an area between the first guide rail and the second guide rail, at right angles to a longitudinal extent of the first guide rail and / or the second guide rail.
[0011] This makes it possible to guide a rope in such a way that an opening remains free in the open position. In other words, the rope runs essentially outside the opening. At the same time, sufficient compensation for a tipping moment can still be ensured.
[0012] An arrangement according to the invention comprises a fixed structure, at least one opening formed therein, at least one cover element and at least one guide system according to the invention, wherein the cover element is movable by the guide system between a first position, preferably a closed or intermediate position, and a second position, preferably an open position.
[0013] Further advantageous embodiments of the invention are defined in the dependent claims.
[0014] It can be provided that the deflection device comprises at least three, preferably exactly three, deflection rollers.
[0015] Preferably, it can be provided that two of the at least three deflection rollers are arranged on or in the region of the first guide rail and another of the at least three deflection rollers is arranged on or in the region of the second guide rail.
[0016] This allows a deflection device to be constructed in a simple and cost-effective manner
[0017] way be realized .
[0018] Advantageously, two of the at least three rollers (preferably one roller in the area of the first and one roller in the area of the second guide rail) serve to guide the rope orthogonally and another of the at least three rollers (preferably the second roller in the area of the first guide rail) serves to deflect the rope onto a guide body.
[0019] Preferably, a shortening mechanism can be provided, via which a length of the at least one cable can be adjusted between a first and a second position depending on a position of the cover element.
[0020] The further a cover element is moved from a first position to a second position, i.e., the further a cover element is opened, the greater the resulting tilting moment becomes, since the acting lever is lengthened. This is not taken into account in the prior art, meaning that a tilting moment is essentially only compensated for in one position of the cover element. In all other positions, over- or undercompensation occurs.
[0021] This problem can be solved with a shortening mechanism, which changes the effective length of the cable depending on the position of the cover element. In a closed or intermediate position of the cover element, the cable is therefore at its longest, while it shortens with increasing opening to accommodate the increasing tipping moment.
[0022] Conversely, the effective length of the rope is extended when moving from an open position to a closed or intermediate position via the shortening mechanism.
[0023] The tilting moment of the cover element can therefore always be compensated accordingly. It is also conceivable to deliberately overcompensate in order to lift the cover element.
[0024] The shortening mechanism can be designed in the form of a conical pulley. This represents a simple way of implementing a shortening mechanism. For example, the conical pulley can be wrapped around by at least one rope.
[0025] It is also conceivable to provide a stepped roller, two rollers of different sizes that are rotatably connected to one another, or a roller with a special contour. Preferably, the shortening mechanism can also have at least one guide groove in which the at least one cable is guided.
[0026] Particularly preferably, the at least one guide groove can extend spirally along a conical section of the conical roller.
[0027] This ensures that at least one rope is guided safely and correctly on the conical pulley.
[0028] According to a further embodiment of the invention, at least one cable tensioning device, preferably at least two cable tensioning devices, can be provided for tensioning the at least one cable.
[0029] This means that a rope can be tensioned and adjusted accordingly, for example after the guide system has been installed, in order to ensure that the guide system functions properly.
[0030] It can be provided that the at least one cable tensioning device has a tool holder, preferably in the form of a screw-head drive, for actuating the cable tensioning device. This allows for simple actuation of the cable tensioning device.
[0031] Advantageously, the at least one cable tensioning device can be arranged on or in the shortening mechanism. This allows the cable tensioning device to be provided with a small footprint.
[0032] However, it is also conceivable for the at least one cable tensioning device to be arranged on one of the guide bodies. Preferably, the cable tensioning device can be provided with a cable drum onto which the at least one cable can be wound or unwound. This represents a simple implementation of a cable tensioning device.
[0033] However, other designs of a rope tensioning device are also conceivable. For example, a thread pressed onto at least one end of the rope could be provided. The rope tension could then be adjusted using a nut arranged on this thread. In principle, any suitable type of rope tensioning device is conceivable.
[0034] The cable tensioning device can also be provided with a locking device for locking the cable tensioning device. This prevents the cable tensioning device from being accidentally activated or from coming loose.
[0035] In one embodiment, the locking device can comprise a locking mechanism and / or a locking pin. Particularly when both a locking mechanism and a locking pin are provided, a particularly secure locking of the cable tensioning device can be achieved.
[0036] Particularly preferably, the at least one cable can be formed from at least two sections. This facilitates the assembly and adjustment of a compensation device.
[0037] It can also be provided that one of the at least two sections can be rolled onto the conical roller during a movement of the cover element between a first and a second position, and the other of the at least two sections can be unrolled from the conical roller. In this embodiment, the cable is shortened because, due to the conical shape of the roller, not as much cable is unrolled as wound up.
[0038] Particularly preferably, it can be provided that at least one connecting device is provided for connecting the at least two sections of the at least one cable, preferably wherein the connecting device is formed by the shortening mechanism and / or the at least one cable tensioning device.
[0039] In particular, if the connecting device is formed by the shortening mechanism and / or the at least one cable tensioning device, the result is a compensation device which is easy to assemble and adjust and which is also designed to save space.
[0040] With regard to an arrangement according to the invention, it can be provided that the cover element is designed to be substantially square, the guide system has four hinges which are arranged in the first position in the region of the four corners of the cover element, preferably wherein two hinges are arranged vertically spaced from one another on the fixed structure and two hinges are arranged vertically spaced from one another on the cover element and are connected to the cover element in a movement-coupled manner.
[0041] On the one hand, the cover element can be guided via the hinges. On the other hand, the cover element can be transferred via the hinges from a closed position, in which the cover element closes the opening, to an intermediate position, in which the cover element is arranged in front of the opening but orthogonally spaced from it. It can also be provided that the at least one cable is arranged substantially, preferably entirely, outside a region of the opening.
[0042] This leaves an opening free, allowing a window or door to remain fully usable.
[0043] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings.

[0082] Fig . 10c a third step for tensioning a rope with a rope tensioning device .
[0083] Figures 1a to 1c show three preferred positions of an arrangement, the positioning of the arrangement in Figure 1a corresponding to a closed position, in Figure 1b to an intermediate position, and in Figure 1c to an open position. In the closed position (Fig. 1a), the cover element 101, here in the form of a window, is completely closed, whereas in the intermediate position (Fig. 1b) it is orthogonally spaced from the opening 101a. In the open position, the cover element 101 is completely open, and the opening 100a is accessible.
[0084] In this exemplary embodiment, the intermediate position corresponds to a first position, and the open position to a second position. However, it is also conceivable that no intermediate position is provided, but rather that the cover element 101 can be moved directly from a closed position to an open position. In this case, the closed position would correspond to the first position.
[0085] The arrangement comprises an electric drive device 12, a cover element 101 in the form of a window which is displaceable relative to a fixed structure 100 for closing an opening 100a of the fixed structure and a guide system 1 with which the cover element 101 is displaceable relative to the fixed structure 100 for exposing or covering the opening 100a.
[0086] Figure 2a shows a fixed structure 100, and Figure 2b shows a guide system 1 and a cover element 101. The guide system 1 comprises a first guide rail 2 and a second guide rail 4 for the relative movement of the cover element 101 with respect to the fixed structure 100.
[0087] The first guide rail 2 and the second guide rail 4 are arranged in a component block 102 for connecting the fixed structure 100.
[0088] In addition, additional guide rails 13, 14 are integrated into a frame 101a of the cover element 101 and recessed therein.
[0089] The cover element 101 can be arranged substantially flush with the fixed structure in the closed position and arranged parallel to the fixed structure 100 in the intermediate position and in the open position.
[0090] Figure 3a shows the intermediate position, and Figure 3b shows the closed position of the cover element relative to the guide system in a sectional view. Figure 3c shows detail A of Figure 3b. It can be seen that two displaceably mounted and horizontally oriented synchronization rods 15 are provided.
[0091] Figures 4a to 4f show possible constructions of the cover element 101 in the form of a window, whereby other constructions or material combinations are also possible in order to reduce thermal conductivity and / or thermal bridges.
[0092] In Figure 4a, a construction with a vacuum insulating glass unit with a wooden frame connected to an aluminum profile is selected. In Figure 4b, a vacuum insulating glass unit is arranged on an aluminum profile without wood-like materials. In Figure 4c, the cover element 101 comprises a stepped glass unit in combination with wood and aluminum. In Figure 4d, a vacuum insulating glass unit is connected to a plastic profile and an aluminum profile. In Figures 4e and 4f, a multi-pane insulating glass unit is connected to wood and aluminum with different geometries for connection to a
[0093] Guide system 1 arranged .
[0094] Figure 5a shows the guide system 1 in isolation in the closed position, wherein the synchronization rods 15 are slidably mounted in a fixed bearing of hinges 16, although this is not absolutely necessary.
[0095] The drive device(s) 12 interact with four hinges 16, each comprising two toggle levers 17.
[0096] Figure 5b shows detail A of Figure 5a .
[0097] Figure 5c shows the guide system 1 in an intermediate position, while Figure 5e shows the guide system 1 in the fully open position of the cover element 101. Figure 5d shows detail A of Figure 5c, and Figure 5f shows detail A of Figure 5e.
[0098] Figure 5e shows, in comparison to Figure 5c, that two hinges 16 are arranged stationary on the guide rails 2, 4 and two hinges 16 are arranged stationary on the additional guide rails 13, 14, so that the additional guide rails 13, 14 are movable relative to the guide rails 2, 4, wherein two hinges 16 are displaceable relative to two hinges 16.
[0099] Figure 5g shows a schematic perspective view of the detail A of Figure 5e from a different angle , wherein the guide rail 14 is movable parallel relative to the guide rail 4 .
[0100] In Figure 6a, a hinge 16 is shown in the closed position, which can be moved into the intermediate position and the open position in Figure 6c via the relative arrangement of the two toggle levers 17 in Figure 6b in order to be able to move the cover element orthogonally and parallel relative to the guide system.
[0101] The hinge 16 comprises a guide body 3, 5, 18, 19, wherein generally two guide bodies 3, 5 are movable on the guide rails 2, 4 and two guide bodies 18, 19 are movable on the guide rails 13, 14.
[0102] Figure 6d shows the hinge 16 in an exploded view, with two articulated levers per toggle lever 17 being connected to one another via an articulated connection.
[0103] It can also be seen that the guide bodies 3, 5, 18, 19 have three rollers 11. Guide bodies 3, 5, 18, 19 with a different number of rollers 11 are also conceivable. Figure 7a shows a schematic, perspective view of a compensation device 6, a first guide body 3 and a cover element 101 in a closed or intermediate position, Figure 7b in a half-open position and Figure 7c in an open position.
[0104] A deflection device 8 is visible, which has three deflection pulleys 8a. The cable 7 is deflected via the deflection pulleys 8a. The cable 7 is deflected in such a way that an opening 100a, which is located in the area delimited by the cable 7, remains free.
[0105] In the simplest case, the cable 7 can be a simple, one-piece cable. In the present exemplary embodiment, the cable 7 is composed of two sections 7a, 7b. The first section 7a is arranged with one end on a shortening mechanism 9. The other end is deflected by 180° via the deflection pulley 8a and is arranged on the first guide body 3. The second section 7b is arranged with one end on the shortening mechanism 9 and with the other end directly on the second guide body 5.
[0106] The shortening mechanism 9 thus acts as a connecting device. In the present embodiment, the shortening mechanism 9 is designed as a conical roller. The shortening mechanism 9 is rotatably mounted on a component support 102.
[0107] In the closed or intermediate position (Figure 7a), the cover element 101 is arranged in front of the opening 100a. If the cover element 101 is moved, the guide bodies 3, 5 move along the guide rails 2, 3. The cable 7 stabilizes the cover element 101. The second section 7b is wound onto the shortening mechanism 9 and the first section 7a from the
[0108] Shortening mechanism 9 unrolled.
[0109] In Figure 7b, the cover element 101 is in a half-open position. The cover element 101 has been displaced relative to the position in Figure 7a and exposes part of the opening 101a. It can be seen that the guide bodies 3, 5 have been displaced along the guide rails 2, 4 (not shown).
[0110] The lower section 7b of the cable 7 is arranged directly on the carriage 5. When the cover element 101 is moved, the section 7b is wound onto the shortening mechanism 9, while the upper section 7b is unwound from the shortening mechanism 9. The section 7a is also deflected onto the guide body 3 via the deflection roller 8a in the upper right corner.
[0111] In Figure 7c, the cover element 101 is in an open position and completely exposes the opening 101a. It can be seen that the guide bodies 3, 5 have been displaced even further, and the section 7b has been further rolled onto the shortening mechanism, and the section 7a has been further unrolled from the shortening mechanism 9.
[0112] A tilting moment K occurring on the cover element 101 can be compensated for by the compensation device 6. The guide body 3 is "held back" by deflecting the upper section 7a of the cable 7 onto the guide body 3. This means that forces resulting from the tilting moment K can be absorbed by the cable 7, thereby compensating for the tilting moment K.
[0113] Since the tilting moment K also increases with increasing opening of the cover element 101 (due to the larger lever), it is advantageous if the effective length of the cable 7 can be adjusted. This can be achieved via the shortening mechanism 9.
[0114] In Figure 8a, the shortening mechanism 9 is shown in a first position (closed or intermediate position), in Figure 8b in a partially open position and in Figure 8c in a second position (open position).
[0115] It can be seen that the cable 7 has two sections 7a, 7b. The section 7a is arranged on a side 9b with a smaller diameter on or in the shortening mechanism 9. The section 7a is guided in the guide groove 9a, specifically for three turns. The section 7b, on the other hand, is arranged on a side 9c with a larger diameter on or in the shortening mechanism 9. The section 7b is also guided in the guide groove 9a, but only for one turn.
[0116] If the cover element 101 is now displaced, the guide bodies 3, 5, on which the sections 7a, 7b are arranged accordingly, also move. As a result, the shortening mechanism 9 rotates about a rotation axis A. As a result, the first section 7a is unrolled along the groove 9a and the second section 7b is rolled up along the groove 9a. This continues until the cover element 101 is arranged in a second position, here: an open position, or until the movement of the cover element 101 is stopped.
[0117] Since the shortening mechanism 9 is designed as a conical roller, less is rolled off the section 7a (since it is arranged on the side 9b with the smaller diameter) than is rolled up from the section 7b (since it is arranged on the side 9c with the larger diameter). Due to the design as a conical roller, as the cover element 101 opens more and more, less and less of the section 7a is rolled off. As a result, the upper section 7a is shortened in comparison to the lower section 7b, as a result of which the guide body 3 is held back more strongly as the cover element 101 opens more and more. As a result, the increasing tilting moment K can always be compensated for accordingly.
[0118] In principle, it is also conceivable for the shortening mechanism 9 to be designed as a stepped roller or as two or more rotatably connected rollers with different diameters. This also allows the described principle of shortening a section 7a to be implemented. However, this does not allow for a continuous change in the compensation of the tilting moment K.
[0119] It is also conceivable to design the shortening mechanism 9 as a roller with a special contour, such as a hump, ramp, and a flat section or a step. Other contours are also conceivable. This allows the compensation of a tilting moment K to be adapted to specific conditions.
[0120] The sections 7a, 7b of the cable 7 can be arranged on or in the shortening mechanism 9 by known means (for example, by clamping). Advantageously, however, the sections 7a, 7b are arranged on the shortening mechanism 9 via a cable tensioning device 10, which is arranged in or on the shortening mechanism 9.
[0121] Figure 9 shows an exploded view of a shortening mechanism 9 with two cable tensioning devices 10. It can be seen that the shortening mechanism 9 has two openings 9d. A cable drum 10b can be inserted into each of these openings 9d. The cable drum 10b is then rotatably and displaceably mounted in the respective opening 9d. In addition, insertion openings 9e are provided, through which the sections 7a, 7b of the cable 7 are inserted into the shortening mechanism 9 and the
[0122] Cable tensioning devices 10 can be supplied. The cable drums 10b each have a toothing 10c and a tool holder 10a for actuating the cable tensioning devices 10. A locking mechanism 20a can be formed via locking pins 10d in cooperation with the toothing 10c. In addition, locking pins 20b are provided for additional securing of the cable tensioning device 10. The locking mechanism 20a and a locking pin 20b each form a locking device 20. It is also conceivable that only one locking mechanism 20a or only one locking pin 20b is provided.
[0123] Figures 10a to 10b show steps for tensioning a cable 7, here section 7a. Tensioning is performed analogously for section 7b.
[0124] It can be seen that the section 7a is inserted into the shortening mechanism 9 and into a slot 10f in the cable drum 10a. The cable drum 10b is mounted in the opening 9d. The opening 9d is designed as an elongated hole, allowing the cable drum 10b to be not only rotatable but also displaceable. A locking pin 10d is also visible.
[0125] If the cable tensioning device 10 is actuated (i.e. the cable drum 10b is rotated), the section 7a is at least partially wound onto the cable drum 10b (not shown here). This tensions the cable 7 and moves the cable drum 10a in the direction of the locking pin 10d. The locking mechanism 20a is now formed via the toothing 10c and the locking pin 10d. This allows further rotation of the cable drum 10b (i.e. tensioning of the section 7a), but maintains the cable tension when the cable tensioning device 10 is no longer actuated (Fig. 10b). In the event that there is no tension on the cable 7 (section 7a) in a position of the guide system 1, an additional locking pin 20b is introduced. This locking pin 20b engages with the toothing 10c and prevents the cable drum 10b from shifting to an initial position as shown in Figure 10a. The cable tensioning device 10 is thus locked.
