DETAILED DESCRIPTION OF THE INVENTION

(21) FIG. 1 shows, by way of example and diagram, a section of an external faade of a building. The external faade has a large number of faade elements 20 which are arranged side by side and on top of one another, and which delimit a building interior to the outside. FIG. 1 graphically highlights, by way of example, such a faade element 20 by a border.

(22) The faade elements 20 each comprise a faade element frame 21 and a panel element 22, which can be e.g. a fixed glazing. Alternatively, the panel element 22 can be part of a window sash that can be opened. In the embodiment shown, one vertical sliding element 1 each is provided to the side next to the panel element 22 of a faade element 20. The vertical sliding element 1 has an element frame 2 and a sash 3, which can be moved in a vertical direction relative to the element frame 2. The element frame 2 can be formed at least in sections by frame sections of the faade element frame 21. For example, the sash 3 can be provided between a standing profile section of the faade element frame 21 and a transom 23, which separates sash 3 from the panel element 22.

(23) FIGS. 2a to 2c each show vertical sections through a faade element 20 in the area of the vertical sliding element 1, namely FIG. 2a shows a closed position, FIG. 2b a partially open position, in which the sash 3 is moved in front of the opening by parallel parking in the horizontal direction, without or substantially without a vertical movement component, and FIG. 2c an open position, in which the sash 3 of the vertical sliding element 1 is positioned in an open position by vertical displacement. In the following figures, area I refers to an interior area within the building and area A to an exterior area in front of the building.

(24) The element frame 2 of vertical sliding element 1 has an opening which is closed in the closed position of sash 3 by the latter and is at least partially released in an open position or in a partially open position. In particular, the opening can be an elongated opening where the opening height is considerably greater than the opening width. For example, the opening height can be many times greater than the opening width, for example by a factor in the range from 3 to 10, in particular a factor between 7 and 9. For example, the opening width can be between 100 mm and 200 mm, whereas the opening height is between 800 mm and 1500 mm, in particular between 1000 mm and 1250 mm. Such opening sizes are used e.g. for faades of buildings that have an automatic ventilation system but also offer the possibility for people in the building to ventilate the interior naturally.

(25) The faade element 20 is preferably designed as a flush-mounted faade element, i.e. in the closed position of the sash 3, the outside of the sash is flush with the outside of element frame 2.

(26) The vertical sliding element 1 has an opening mechanism for opening the sash 3, which comprises a plurality of parking scissors 7. Using these parking scissors 7, the sash 3 can be positioned from the closed position (FIG. 2a) into a partially open position (FIG. 2b). This partial opening takes place in particular in such a way that the sash 3 is placed parallel in front of the opening of the element frame 2, i.e. the sash 3 is moved from the closed position parallel in the direction of the inner area I of the building by means of the parking scissors 7. In so doing, the orientation of the sash remains unchanged or substantially unchanged (i.e. the vertical axis of the sash is aligned vertically or substantially vertically).

(27) After moving the sash 3 into the partially open position, it can then be moved into the open position shown in FIG. 2c by moving it vertically downwards (sliding direction VR). For this purpose, the sash 3 is movably guided, by means of guide rails 5 provided in the element frame 2, relative to this element frame 2. The guide rails 5 are mounted in particular on side faces 2.1, 2.2 of the element frame 2, preferably in such a way that in the closed position they are accommodated in a fitting chamber with their upper partial length. In the closed position of the sash 3, this fitting chamber is limited on the outside by the side faces 2.1, 2.2 of the element frame 2 and on the inside by the side faces 3.1, 3.2 of sash 3. In particular, a first guide rail 5 is provided between the side face 2.1 of element frame 2 and the side face 3.1 of the sash 3, and a second guide rail 5 is provided between the side face 2.2 of element frame 2 and the side face 3.2 of the sash 3, so that the sash 3 is guided on both sides in element frame 2.

(28) The guide rails 5 each have a guide contour. For example, the guide rails 5 can have a C-shaped, or substantially C-shaped, cross-section. Other guide contours are also conceivable.

(29) These guide rails 5 each contain guide elements in the form of sliding carriages 6, which are movably guided in the respective guide rails 5 in the sliding direction VR. Other types of guide elements are also conceivable. The sliding carriages 6 can preferably be mounted in a form-fit fashion in the respective guide rail 5. These sliding carriages 6 are connected at least indirectly to the parking scissors 7 and the latter, in turn, to the sash 3. This allows the sash 3 to be moved vertically by means of sliding carriages 6 guided in the guide rails 5, as shown in FIGS. 2b and 2c.

(30) Stops 5.1, 5.2 are provided to limit the upward and downward sliding movement of the sash 3. For example, the upper stop 5.1 limits the upward sliding movement of the sash 3 and the lower stop 5.2 limits the downward sliding movement of the sash 3. The stops 5.1, 5.2 can be designed as rubber buffers, for example. These stops 5.1, 5.2 can in particular form limits for the sliding carriages 6, i.e. the upper sliding carriages 6 run on upper stops 5.1 and the lower sliding carriages 6 run on lower stops 5.2.

(31) FIG. 3 shows the vertical sliding element 1 and its fittings in a greater degree of detail in a perspective sectional view.

(32) The sliding carriages 6 are preferably provided on a support bar 8. The guide rails 5 provided on both opposite sides of the sash 3 are each assigned a support bar 8. The support bar 8 can be made of a flat material, for example. It extends preferably parallel or substantially parallel to the guide rail 5. The sliding carriages 6 are arranged either directly or indirectly on this support bar 8 via sliding carriage carriers 6.1. Therefore, the support bar 8 and the sliding carriages 6 provided on it are movably guided on the guide rail 5.

(33) As can be seen in FIG. 3 in particular, the parking scissors 7 are articulated with the support bar 8, on the one hand, and with the sash 3, on the other hand.

(34) The parking scissors 7 each comprise at least two scissors legs 7.1, 7.2, namely at least one long scissors leg 7.1 and one short scissors leg 7.2. The long scissors leg 7.1 is pivotally connected to the support bar 8 via a first free end and has a sash fastening element 7.3 at a second free end opposite the first free end, by means of which the long scissors leg 7.1 is connected to the sash 3. The long scissors leg 7.1 is pivotally connected to the sash fastening element 7.3.

(35) The short scissors leg 7.2 is articulated at a first free end in a central area of the long scissors leg 7.1 to the latter, i.e. a hinge point connecting the scissors legs 7.1, 7.2 lies between the free ends of the long scissors leg 7.1. At a second free end, the short scissors leg 7.2 is connected at least indirectly pivotally and movably to the support bar 8. The movability of the short scissors leg 7.2 in relation to the support bar 8 can be achieved in particular by means of an elongated hole 8.1, which is provided in the support bar 8. The short scissors leg 7.2 can either engage directly in this elongated hole 8.1 by means of a pin-shaped connecting element or the short scissors leg 7.2 can be coupled with the support bar 8 via a sliding carriage carrier 6.1, as shown in FIG. 3. In particular, the sliding carriage carrier 6.1 can be movably guided in the elongated hole 8.1 of the support bar 8 and connected to the short scissors leg 7.2 via a bolt-shaped connecting member. This allows a space-saving arrangement of the parking scissors 7 in the fitting, in particular in the closed position of sash 3.

(36) The arrangement of the scissors' legs 7.1, 7.2 of the parking scissors 7 can be such that they are received in the fitting chamber in the closed position with their longitudinal axis aligned vertically or substantially vertically. When moving the sash 3 to the partially open position shown in FIG. 3, the scissors legs 7.1, 7.2 are counter-pivotable in such a way that the long scissors leg 7.1 runs at an acute angle oblique to the vertical, this angle opening upwards, and the short scissors leg 7.2 runs at an acute angle oblique to the vertical, this angle opening downwards.

(37) The scissors legs 7.1, 7.2 can be offset at least in sections to allow the legs 7.1, 7.2 to pivot into a pivoting position in which the scissors legs 7.1, 7.2 and the support bar 8 run parallel or substantially parallel.

(38) FIGS. 4a and 4b show the locking mechanism by means of which the sash 3 is fixed in the closed position relative to element frame 2. The sash 3 is provided with sash-side locking members, which are formed, for example, by a driving rod 11 which is slidable in the vertical direction and on which locking bolts 11.1 are provided. The driving rod 11 can be moved in a known manner by an actuating element, for example by a rotatable or foldable handle element.

(39) The locking blocks 12 cooperating with the locking bolts 11.1 are provided on the support bars 8 and are therefore also displaced with the support bars 8 when the sash 3 moves vertically. The sash 3 is therefore not locked directly opposite the locking blocks 12 provided on the element frame 2, but indirectly opposite this element frame 2, namely via the support bar 8, which, in turn, is movably held in the guide rails 5 provided on the element frame 2. In the closed position of the sash 3, the latter is thus secured against parallel parking via the locking members. The vertical sliding movement of the sash 3 is prevented by the positive engagement of the sash 3 in the opening provided on element frame 2 or the upper stop 5.1.

(40) The locking bolts 11.1 are preferably designed as adjustable elements. They can be turned closer to or away from the locking blocks 12 via an eccentric pivot point. This allows the contact pressure generated by the lock to be varied as required.

(41) FIGS. 5 to 8 each show horizontal sectional views through a faade element 20, FIGS. 5, 7 and 8 showing the closed position and FIG. 6 the open position of the sash 3.

(42) In the embodiment shown, the element frame 2 is arranged to the side next to a panel element 22 (not shown), for example a fixed glazing, and is formed at least in sections by the faade element frame 21. In order to separate the panel element 22 from the sash 3, a transom 23 is provided, which forms a further section of element frame 2. The element frame 2 or the faade element frame 21 is formed from composite profiles, in particular aluminum composite profiles, which consist of e.g. an inner and an outer profile, which are arranged spaced apart from one another by a thermal separation. The composite profiles have a profile depth T in the range between 170 mm and 250 mm, in particular 190 mm to 220 mm, most preferably 200 mm. In particular, the inner profile (profile section 2.3 protruding inwards from the thermal separation) of the composite profile has a profile depth in the range between 100 mm and 150 mm, in particular between 120 mm and 140 mm. Such a large profile depth T makes it possible for the sash 3 to be flush-mounted on the inside in the open position.

(43) The fitting allowing the parking movement and vertical sliding movement of the sash 3 is formed, as previously mentioned, by a pair of guide rails 5 provided on opposite sides 2.1, 2.2 of element frame 2. These guide rails 5 are integrated in intermediate spaces 4, which, in the closed position of the sash 3, are formed between the side faces 2.1, 2.2 of element frame 2 and the opposite side faces 3.1, 3.2 of the sash 3. In other words, the side faces 2.1, 2.2 of the element frame 2 opposite at the same height in the closed position of the sash 3 and the side faces 3.1, 3.2 of the sash 3 define a fitting chamber into which the guide rails 5 are integrated.

(44) The depth of the guide rails 5 is essentially equal to the depth of the fitting chamber which is spatially limited in the closed position. In particular, the depth t of the guide rails 5 is substantially smaller than the depth T of the profile section 2.3 projecting inwards from the thermal separation. As a result, in the closed position, the guide rails 5 can be received in the fitting chamber in such a way that they are invisible from the front.

(45) As can be seen in particular in FIGS. 5 and 5a, the parking scissors 7 are designed in such a way that, in the closed position of the sash 3, the scissors legs 7.1, 7.2, which are vertically aligned with their longitudinal axes between the guide rail 5 and the side faces 3.1, 3.2 of the sash 3, are accommodated in the fitting chamber.

(46) As can be seen in particular in FIG. 6, the sash 3 has a sash depth FT, which is equal to or less than half the depth ET of element frame 2, in particular in the area of profile area 2.3 (FTET/2). This means that, when closed, the sash 3 is flush-mounted on the outside or is substantially flush-mounted on the outside with element frame 2 and, when open, is flush-mounted on the inside with the inner side of element frame 2. In other words, the swing-out movement required to open the sash 3 takes place completely within the element frame 2, i.e. in the open state, the sash 3 does not project beyond the plane spanned by the inner sides of element frame 2.

(47) In order to be able to optically cover the guide rails 5, sliding carriages 6 and swing-out scissors 7 in the closed position, the sash 2 has cover sections 3.3 on the inside. The cover sections 3.3 protrude laterally from the inside of the sash in a horizontal direction and thus at least partially close the intermediate space between the element frame 2 and the sash 3 (limited by the side faces 2.1, 2.2, 3.1, 3.2), in which the guide rails 5, sliding carriages 6 and swing-out scissors 7 are provided. Preferably, the cover sections 3.3 are dimensioned in such a way that a circumferential shadow groove, for example a shadow groove in the range of 2 to 6 mm, in particular 4 mm, results in the closed position. As can be seen e.g. in FIGS. 5 and 5a, an optically inconspicuous integration of the fitting parts is thus achieved.

(48) FIG. 6 shows an example of a horizontal sectional view through a faade element 20 in an area below the opening that can be closed by the sash 3 and with a sash 3 in the open position. The element frame 2 is filled in this area by a faade element section 24. On the inside in front of the faade element section 24, a chamber 13 is formed, which is closed in the direction of the interior I by a cover 13.1. In particular, the cover 13.1 can be a removable cover. This makes it possible to remove the cover 13.1 when installing the window or during installation work in order to make the area below the opening that can be closed by the sash 3 in the closed position accessible.

(49) Shadow grooves 13.2 are respectively provided between the cover 13.1 and the profile sections 2.3, through which the scissors legs 7.1, 7.2 can be passed. In particular, the scissors legs 7.1, 7.2 are positioned above the shadow grooves 13.2 when opening the sash 3, so that the scissors legs 7.1, 7.2 can be inserted into the shadow grooves 13.2 from above when vertically moving the sash 3.

(50) By analogy with the chamber 13, a chamber 14 can also be provided above the opening closed by the sash 3 in the closed position, which can also be closed, for example, by a removable cover 14.1. This makes it possible to create a room accessible from the inside even above this opening, which can be used for maintenance and installation work, and also to accommodate other functional elements.

(51) As previously mentioned, the vertical sliding element has a locking mechanism in which locking bolts 11.1 arranged on a driving rod 11 on the sash side cooperate with locking blocks 12 arranged on the support bars 8.

(52) FIG. 7 shows a horizontal sectional view through a faade element 20 with a sash 3 in the closed position in an area in which the locking bolts 11.1 or locking blocks 12 are provided. When locking the sash 3, the locking bolts 11.1 engage behind the locking blocks 12 so that a parallel parking of the sash 3 is blocked.

(53) As shown in FIGS. 2a to 2c, the sash 3 can be operatively connected to members via which a weight compensation of the sash 3 can be affected. In particular, the weight compensation can be used to decelerate the sash 3 during opening in order to prevent the sash 3 from accelerating excessively during the vertical downward sliding movement and hitting the stop 5.2 in an unintentionally strong fashion. Conversely, during closing, the weight compensation can be used to move the sash 3 upwards, supported by the weight compensation, so that a person operating the sash 3 does not have to lift the entire weight of the sash 3. In addition, as a result of the weight compensation the sash can be positioned in a desired sliding position, i.e. e.g. in a partially open position, without the sash 3 always continuing to move into the fully open position due to gravity. In other words, the weight compensation can form a weight element that compensates the gravitational force of the sash 3.

(54) The weight compensation can be realized in different ways. For example, a counterweight 15 can be provided which is adapted to the weight of the sash 3, the counterweight 15 being selected to be in particular slightly lighter than the weight of the sash 3. The counterweight 15, for example, can be movably integrated in the frame profile of the element frame 2, in particular in the profile section 2.3. As shown in FIG. 8, the counterweight 15 is here coupled to the sash 3 via a connecting member 15.1, for example a rope, via at least one deflection roller 15.2. This means that, when the sash 3 is opened, the counterweight 15 is raised by a vertically downward sliding movement, counteracting the gravitational force acting on the sash 3 and then supporting the closing movement by lowering the counterweight 15 when closing the sash 3.

(55) In order to prevent the counterweight 5 from falling without deceleration onto the floor of the element frame 2 when the connecting member 15.1 breaks off, a damping element, e.g. a damping element containing a spring, can be provided in the element frame 2, which in this case absorbs the impact of the counterweight 15. In order to be able to replace the damping element and/or to carry out maintenance work in the area of the damping element, the element frame 2 can have, in the area of the damping element, an inspection opening which can be closed e.g. by a cover.

(56) In the embodiment shown, the counterweight 15 is movably guided on a guide element 16, which is provided inside the profile section 2.3. The guide element 16 can be in particular a guide rail. Maintenance-free plain bearings can preferably be provided between the counterweight 15 and the guide element 16, by means of which low-friction guidance of the counterweight 15 on the guide element 16 is achieved.

(57) The connection members 15.1 preferably establish a connection between the counterweight 15 and a support bar 8. This ensures that the connecting members 15.1 are not deflected by the parallel parking of the sash 3 in the direction of the interior area I.

(58) To ensure that the sash 3 is suspended as distortion-free as possible, each of the two support bars 8 is preferably coupled to the counterweight 15 via connecting means 15.1 and corresponding deflection rollers 15.2. Preferably, a connection member 15.1 on the top and closed by the cover 14.1 spans the narrow opening side formed in the element frame in order to be coupled to the support bar 8 located at a distance from the counterweight 15.

(59) FIGS. 9a, 9b and 10a, 10b show the fittings used for the sliding and parallel parking movement of the sash 3, the guide rails 5 not being shown in the drawings for reasons of clarity.

(60) In addition to the pair of guide rails 5 which can be attached to the element frame 2, the fitting of vertical sliding element 1 comprises a pair of support bars 8. The slide carriages 6 are preferably attached to the support bars 8 via sliding carriage carriers 6.1. Furthermore, the support bars 8 are each provided with a pair of parking scissors 7, which can be opened (FIG. 9a, FIG. 10a) or closed (FIG. 9b, FIG. 10b) for parallel parking of the sash 3.

(61) As described above, the support bars have 8 elongated holes 8.1, which allow the opening and closing of the parking scissors 7. In the embodiment shown, a free end of the short scissors leg 7.2 is pivotally connected to the sliding carriage carrier 6.1. This sliding carriage carrier 6.1, in turn, is movably guided in the area of the free end opposite the short scissors leg 7.2 in the elongated hole 8.1. By moving the sliding carriage carrier 6.1 in the elongated hole 8.1, the position of the free end of the short scissors leg 7.2 is changed and the parking scissors 7 are thus opened or closed.

(62) The support bar 8 has a recess 8.3 in the area in which the sliding carriage carrier 6.1 is provided. In this recess 8.3, the free end of the long scissors leg 7.1 can be accommodated in the closed position of the sash 3, namely an upper section of the long scissors leg 7.1, on which the sash fastening element 7.3 is provided.

(63) In addition, the long scissors leg 7.1 can be offset so that in the closed position of the parking scissors 7 the upper section of the long scissors leg 7.1 lies in the plane spanned by the support bar 8. As can be seen in particular in FIG. 9b, this allows an extremely space-saving arrangement of the fitting in the fitting chamber.

(64) As can be seen in particular in FIGS. 10a and 10b, the connecting members 15.1 are connected to the respective support bar 8 via coupling points 17 in the upper area of the support bars 8. In particular cable tensioners with a thread can be provided at the coupling points 17. The thread of the rope tensioners can be screwed into a thread provided on the support bar 8. This allows a length adjustment or adjustability of the weight compensation of the sash 3 to be achieved.

(65) The support bars 8 and the parking scissors 7 can be made of metal, especially stainless steel.

(66) The sliding carriages 6 can be made of a plastic material, in particular polytetrafluoroethylene, which, for example, has self-lubricating properties. This allows a lubricant-free plain bearing to be achieved between the guide rail 5 and the sliding carriages 6.

(67) A cover element 18 is provided on each side of the sash 3 in the area of the connecting members 15.1. This cover element 18 projects upwards in a vertical direction and covers the connecting members 15.1 at least in the direction of interior area I, so that they are no longer visible from the interior area I. Preferably, the cover element 18 is designed as a U-profile, which is open towards the element frame 2. This allows the cover element 18 to be installed in a technically simple manner and surrounds the connecting members 15.1 on three sides so that it is completely covered.

(68) The cover element 18 is preferably moved in a vertical direction with the sash 3 and/or the support bars 8.

(69) FIGS. 11a, 11b and 12 show a sensor system 30, which is intended for checking the closing state of the vertical sliding element 1. The sensor system 30 comprises at least a first sensor system part 31 and at least a second sensor system part 32. The sensor system 30 can in particular be a magnetic sensor system, i.e. a sensor system which can check the closing state of the vertical sliding element 1 on the basis of a measurement or detection of a magnetic field. One of the sensor system parts 31, 32 can be formed by a magnet, in particular a permanent magnet, and the other sensor system part can be formed by a sensor that detects a magnetic field. In particular, this sensor can be designed to provide information as to whether or how close the magnet is to the sensor. In the embodiment shown, the first sensor system part 31 comprises the magnet and the second sensor system part 31 includes the sensor.

(70) Preferably the first sensor system part 31 is provided on the sash 3 of the vertical sliding element 1 and the second sensor system part 32 is provided on the element frame 2. In the embodiment shown, the sensor system 30 is provided in an upper chamber between the sash 3 and an upper, horizontal profile section of element frame 2, namely in such a way that it is concealed behind the cover section 3.3 of the sash 3 or a cover section 2.4 of element frame 2 (FIGS. 11a and 11b). This allows an optically inconspicuous integration of the sensor system 30 into the vertical sliding element 1. It goes without saying that other arrangement options are also conceivable in principle.

(71) The sensor system 30 is preferably designed or arranged in such a way that the closed position is only detected when not only the sash 3 is in the closed position, but the sash 3 is also locked. For this purpose, e.g. a sensor system part 31, 32, in the embodiment shown the first sensor system part 31, is coupled to the driving rod 11. This coupling is realized in the embodiment shown by means of an angle element 33. Other coupling members are also conceivable in principle. This allows the first sensor system part 31 to be positioned in the upper chamber between the sash 3 and the upper, horizontal profile section of element frame 2 and simultaneously coupled to the moving driving rod 11.

(72) FIG. 11a shows the arrangement of the two sensor system parts 31, 32, relative to each other, in the closed position of the sash 3 in the unlocked state. FIG. 11b, on the other hand, shows the arrangement of the two sensor system parts 31, 32, relative to each other, in the closed position of the sash 3 in the locked state.

(73) If the unlocked sash 3 moves into the closed position, the distance between the two sensor system parts 31, 32 is so large that either no signal is emitted at all by the sensor system 30 or the signal is characteristic of the unlocked state. If the sash 3 is locked, the driving rod 11 with the sensor system part 31 attached to it is moved upwards. This reduces the distance between the first sensor system part 31 and the second sensor system part 32 in such a way that a signal indicating the locking of the sash 3 is emitted.

(74) Preferably, the sensor system 30 is coupled with a building-side interlocking monitoring device. This device can, for example, be centrally located in the building, on each floor or divided into other sectional arrangements. As a result, central and complete interlock monitoring of a large number of sashes 3 can be achieved via the sensor systems 30 provided on the vertical sliding elements 1.

(75) The invention was described in the foregoing embodiments. It shall be understood that numerous changes and modifications are possible without abandoning the inventive concept on which the invention is based.
