Description

The invention relates to a fitting for a vertical sliding element, a vertical sliding element and a facade element with such a vertical sliding element.

Vertical sliding elements, in particular vertical sliding windows, are generally known. They include a wing that can be displaced in the vertical direction relative to a facade element, for example a fixed facade element or another wing.

On the one hand, vertical sliding elements are known which, even in the closed position, have an offset transversely to the sliding direction in relation to the facade element, relative to which they are displaceable. The displacement of such a vertical sliding element can therefore take place without an opening movement running transversely to the sliding direction.

Furthermore, vertical sliding elements have become known which, in the closed position, are arranged essentially aligned with the facade element, relative to which they are displaceable. Before the vertical displacement, the vertical sliding element is first arranged on the inside in front of the fixed facade element by an opening movement and can then be displaced in the vertical direction relative to it. The opening movement can be carried out using a lever or scissor mechanism or using a rail guide.

The printed matter DE 10 2016 105 064 A1 , DE 25 03 801 A1 , EP 2 175 097 A1 and DE 27 24 149 A1 each reveal sliding windows with a window sash that can be moved vertically.

The problem with vertical sliding elements known from the prior art is that they are often difficult for users to operate and are also disadvantageous in terms of the appearance of the vertical sliding element, since fitting parts often required for displaceability remain visible on the inside even when closed.

Based on this, it is the object of the invention to provide a vertical sliding element that is very comfortable to use and enables optically improved integration of the fittings.

The task is solved by the features of patent claim 1.

Preferred embodiments are the subject of the subclaims.

According to one aspect, the invention relates to a vertical sliding element according to claim 2, comprising an element frame and a wing which can be displaced in the vertical direction relative to the element frame. In the closed position of the sash, a fitting chamber is formed in the spaces laterally delimited by facing side surfaces of the sash and the element frame, in each of which a guide rail and guide elements guided in this guide rail are provided. The wing is connected to the scissors arrangement with several scissors Connected to guide elements. The scissor arrangement is designed for parallel parking of the sash in a partially open position, in which the sash, viewed in the horizontal direction, is in front of an opening in the Element frame is positioned. The guide elements are designed to move the parallel parked wing in the vertical direction by moving the guide elements in the guide rails in order to move the wing from the partially open position into an open position in which the opening in the element frame is released.

The main advantage of the vertical sliding element according to the invention is that the guide rails can be integrated into the fitting chamber as narrow units and can therefore be arranged in the element frame in a visually inconspicuous manner. In addition, the use of guide elements guided in guide rails makes the vertical sliding element easy to operate.

According to the invention, the wing is connected to the guide rails via a pair of support rods. These support rods form support elements for the wing, via which it is held slidably in the guide rails. These support rods are aligned with their longitudinal axes parallel or essentially parallel to the longitudinal axes of the guide rails and remain in the area of the element frame when the sash is opened parallel.

The length of the support rods is preferably at least half of the wing height, in particular at least two thirds of the wing height. A pair of storage scissors is preferably provided on each support rod. The storage scissors provided on a support rod are also preferably designed to have the same shape and function, in particular identically.

The scissors are articulated to the support rods. This allows the sash to be parked away from the support rods.

The support rods are held slidably in the guide rails by several guide elements. Preferably at least two, preferably at least three guide elements are provided on each support rod. The guide elements can in particular be sliding carriages that are made of a plastic material that has self-lubricating properties. The guide elements can also be accommodated in a form-fitting manner in the guide rails, so that the guide elements can only be removed from the guide rail by pushing them out from the top or bottom.

According to one exemplary embodiment, at least two elongated holes are provided in the support rods, which cooperate with the parking scissors and by means of which the parallel parking of the sash is effected. In particular, the elongated holes can be used to enable the storage scissors to be opened or closed by one end of the scissor leg performing a translational movement.

According to one exemplary embodiment, at least two scissors are provided on the opposite, vertical wing sides. This scissor arrangement consisting of at least four parking scissors enables stable parallel guidance of the sash during the parallel parking movement. In other words, the wing always remains vertically or essentially vertically aligned with its vertical axis during the parallel parking movement from the closed position to the partially open position.

According to one exemplary embodiment, the storage scissors each have a long and a short scissor leg. The wing is attached to the free end of the long scissor leg. The short scissor leg limits the pivoting path of the long scissor leg and thus limits the parallel parking of the sash.

According to one exemplary embodiment, the short scissor leg is articulated with a first free end on the long scissor leg and is connected to the guide rail in an articulated and displaceable manner with the second free end. This means that the short scissor leg can limit the parallel parking of the sash.

Preferably, the long and short scissor legs are aligned parallel or substantially parallel in the closed position of the wing. In the (partially) open position, the short scissor leg is aligned at an acute angle obliquely to a vertical or to the support rod, with the angle opening downwards. The long scissor leg, on the other hand, also runs obliquely to the vertical or to the support rod in the (partial) open position, with the angle opening upwards. This ensures that the sash moves from the closed position to the partially open position under its own weight, i.e. the parallel parking takes place without any effort from the user due to the sash's own weight.

According to one embodiment, a free end of the short scissor leg is at least indirectly displaceable on the support rod. This guidance can take place either directly by connecting a free scissor leg to an elongated hole or indirectly via an intermediate coupling element, for example a guide element carrier.

According to one exemplary embodiment, the free end of the short scissor leg is connected to the support rod via a guide element carrier, in particular a sliding carriage carrier, wherein the guide element carrier is slidably guided on the support rod. In other words, the guide element carrier is displaceable, for example guided in an elongated hole on the support rod. The short scissor leg can be connected to the guide element carrier in a pivoting manner. As a result, the elongated hole required for the parallel parking of the sash can be provided higher up on the support rod and thus a larger recess can be achieved in the support rod, into which a free end of the long scissor leg can then pivot when the sash is in the closed position.

According to one exemplary embodiment, locking means provided on the wing side interact with locking means provided on the support rods. Movable locking bolts are preferably provided on the wing and can be moved via a locking mechanism. When locking the sash, these work together with locking blocks provided on the support rods. By providing the element frame-side locking means on the support rods, a space-saving lock can be achieved, since the plane in which the locking bolts or locking blocks are provided can coincide with the plane in which the support rails or the guide rails are provided. This allows the overall depth of the fittings chamber to be significantly reduced.

According to one exemplary embodiment, the wing has laterally projecting blind sections, by means of which the fitting chambers are at least partially covered. These blend sections are special provided on the inside of the wing. The blind sections can in particular be provided all around the wing. Preferably, the blind sections are dimensioned such that a shadow groove is formed between the free end of the blind section and the element frame. This shadow groove can, for example, have a width of 2mm to 6mm, preferably 4mm.

According to one exemplary embodiment, a weight compensation is provided for the vertically displaceable wing. This ensures that the sash does not unintentionally move into the open position too quickly when opening. Furthermore, the weight compensation can make the closing process much easier, as the sash only needs to be raised with little force. The weight compensation is preferably adapted to the weight of the sash in such a way that the sash can be positioned in any open position without the sash moving into the fully open position due to gravity.

According to one exemplary embodiment, the weight is balanced by means of a counterweight, which is coupled to the displaceable wing via a connecting means (e.g. a rope) which is guided over a deflection roller. The counterweight is chosen in such a way that it almost completely compensates for the weight of the sash, so that only small forces have to be used to move the sash into the open or closed position. If necessary, several deflection rollers can also be provided in order to appropriately redirect the connecting means.

The counterweight can be provided in particular in a profile section of the element frame. For example, it can be slidably guided on a slide rail via sliding guides.

According to one exemplary embodiment, a counterweight that balances the weight is connected via connecting means to the support rods provided on opposite sides of the wing. A pair of ropes is preferably provided as a connecting means, the ropes each establishing a connection between one of the support rods and the counterweight. The connecting means can be suitably deflected via deflection rollers.

According to one exemplary embodiment, the wing is arranged flush or substantially flush on the outside in the element frame in the closed position. “Flush” here means in particular that the sash frame or the outer sash surface (in the case of a solid sash without filling or glass) lies in a plane or essentially in a plane with the outer surface of the element frame. However, partial areas of the vertical sliding element provided on the element frame, for example glazing beads etc., can also protrude from this plane.

According to one exemplary embodiment, the wing is in an open position or also in the partially open position, i.e. after being parked in parallel, it is flush or essentially flush with the element frame on the inside. In other words, the sash or sash frame and the inside of the element frame facing towards the interior area lie in a common plane or essentially in a common plane. This allows the sash to be opened in a space-saving manner.

The element frame preferably has a depth greater than twice the wing depth. As a result, the wing can be moved from a closed position, in which the wing is flush on the outside, into an open position, in which the wing is flush on the inside.

According to one exemplary embodiment, the element frame has a section (hereinafter referred to as element frame section) which extends in the direction of the interior of the building and has profile chambers, on the side surface of which the guide rail is provided facing the wing. For example, the section of the element frame having the profile chambers can be made deeper than the wing, so that an area is created between a pair of such element frame sections in which the wing can be received in the open position, preferably in such a way that this wing does not extend over the inside Element frame sections protrude. This allows the guide rail to be integrated into the element frame in a visually inconspicuous manner.

According to one embodiment, the guide rail is provided on a side surface of a vertically extending section of the element frame designed as a profile rail. The profile rail can in particular be formed by an aluminum composite profile comprising a thermal separation, the profile section protruding inwards from the thermal separation having a profile depth such that the guide rail can be integrated. For example, the profile depth can be chosen to be greater than 100mm. This means that the guide rails can be integrated on the side surfaces facing the sash even during opening movements with a large stroke (for example in the range of 50mm to 100mm).

According to one embodiment, the wing is formed by a composite profile without glass or filling elements. In other words, the wing is formed by a composite profile piece that does not form a frame to accommodate the glass or filling element, but rather the composite profile piece is designed to be so wide that it completely closes the opening formed in the element frame in the closed position. The composite profile piece preferably has one or more chambers, which can be partially filled with thermally insulating material. This means that small openings in particular, such as ventilation openings, can be closed by the wing.

According to one exemplary embodiment, a sensor system is provided for monitoring a locking state. This sensor system can be designed in particular to evaluate a magnetic field using a sensor. In particular, it can comprise a first and a second sensor system part, the distance between these sensor system parts relative to one another being changeable during the locking process. In particular, the distance between the sensor system parts can be smaller in the locked state than in the unlocked state, so that locking information is only transmitted to the sensor, for example, when the sash has been locked in the element frame. This makes it possible to centrally monitor the locking status of several leaves.

According to a further aspect, the invention relates to a facade element according to claim 13, comprising a facade element frame, with a surface element provided in the facade element frame and a vertical sliding element according to one of the previously described exemplary embodiments. The vertical sliding element is provided laterally next to the surface element and is designed to release an elongated, vertically oriented ventilation opening in an open position.

The invention relates to a fitting for a vertical sliding element according to claim 1.

The term “inside” in the sense of the invention is used for areas of the facade element or the vertical sliding element that point in the direction of a building interior or for position or direction information in order to denote a position directed into the building interior or a movement in this direction.

The term "outside" in the sense of the invention is used for areas of the facade element or the vertical sliding element that point away from the interior of the building in the direction of an outdoor area located in front of the building or for position or direction information directed away from the interior of the building towards this outdoor area position or a movement in this direction.

The term “profile system” in the context of the invention is understood to mean, in particular, a composite profile that is composed of several individual profile parts, for example an inner profile, an outer profile and an intermediate profile section or a section for thermal separation. These profile individual parts are used together Formation of the composite profile connected. The composite profile can be used to assemble composite profile pieces into a frame that accommodates a surface element.

The term “surface element” in the sense of the invention is understood to mean a flat, in particular flat, element that is inserted into the facade element. The element can, for example, be a glass, in particular an insulating glass, or another filling, for example a non-transparent sandwich panel or similar.

The term “wings” in the sense of the invention means movable elements, in particular window sashes. These can in particular be movable to enable ventilation of a building. A wing can be designed in one piece or in several parts, i.e. include one or more wing parts.

For the purposes of the invention, “guide element” means elements that are designed to interact with a guide rail. The term “guide element” can be understood to mean, in particular, a sliding carriage, a roller or a carriage-like element having several rollers. The guide element can in particular be guided in a form-fitting manner in the guide rail.

For the purposes of the invention, “guide element carriers” are understood to mean support elements on which a guide element can be arranged. The guide element carrier preferably forms a connecting element between a guide element and a support rod.

For the purposes of the invention, the expressions “approximately”, “essentially” or “approximately” mean deviations from the exact one in each case Value around +/- 10%, preferably around +/- 5% and/or deviations in the form of changes that are insignificant for the function.

Further developments, advantages and possible applications of the invention also emerge from the following description of exemplary embodiments and from the figures.

In the Figure 1 A section of an outer facade of a building is shown as an example and schematically. The outer facade has a large number of facade elements 20 arranged next to one another and one above the other, which delimit a building interior to the outside. In Fig. 1 For example, such a facade element 20 is graphically highlighted by a border.

The facade elements 20 each include a facade element frame 21 and a surface element 22, which can be fixed glazing, for example. Alternatively, the surface element 22 can be part of an opening window sash. In the exemplary embodiment shown, a vertical sliding element 1 is provided on the side next to the surface element 22 of a facade element 20. The vertical sliding element 1 has an element frame 2 and a wing 3, which is displaceable in the vertical direction relative to the element frame 2. The element frame 2 can be formed at least in sections by frame sections of the facade element frame 21. For example, the wing 3 can be provided between a standing profile section of the facade element frame 21 and a fighter 23, which separates the wing 3 from the surface element 22.

Figures 2a to 2c each show vertical sections through a facade element 20 in the area of the vertical sliding element 1, namely Figure 2a a closed position, Fig. 2b a partially open position in which the wing 3 is moved in front of the opening by parallel parking in the horizontal direction, with no or essentially no vertical movement component and Fig. 2c an open position in which the wing 3 of the vertical sliding element 1 is positioned into an open position by a vertical displacement. In the following figures, area I denotes an interior area located in the building and area A an exterior area located in front of the building.

The element frame 2 of the vertical sliding element 1 has an opening which is closed by the wing 3 in the closed position and at least partially released in an open position or partially open position. The opening can in particular be an elongated opening in which the opening height is significantly greater than the opening width. For example, the opening height can be a multiple, for example a factor in the range from 3 to 10, in particular a factor between 7 and 9, greater than the opening width. The opening width can, for example, be in the range between 100mm and 200mm, whereas the opening height is in the range between 800mm and 1500mm, in particular in the range between 1000mm and 1250mm. Such opening sizes are used, for example, in the facades of buildings that have an automatic ventilation system, but also give people in the building the opportunity to naturally ventilate the interior.

The facade element 20 is preferably designed as a flush facade element, ie in the closed position of the wing 3, the outside of the wing is arranged flush with the outside of the element frame 2.

To open the sash 3, the vertical sliding element has an opening mechanism that includes several scissors 7. The wing 3 can be moved out of the closed position ( Fig. 2a ) out into a partially open position ( Fig. 2b ) position. 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, ie the sash 3 is moved out of the closed position by means of the parking scissors 7 in parallel in the direction of the interior area I of the building, with the orientation of the sash remaining unchanged or remains essentially unchanged (ie the wing vertical axis is aligned vertically or substantially vertically).

After moving the wing 3 into the partially open position, it can then be moved into the in Fig. 2c Open position shown can be moved by moving in the vertical direction downwards (shifting direction VR). For this purpose, the wing 3 is guided displaceably relative to this element frame 2 by means of guide rails 5 provided in the element frame 2. The guide rails 5 are attached in particular to side surfaces 2.1, 2.2 of the element frame 2, preferably in such a way that they are received in the closed position with their upper partial length in a fitting chamber. In the closed position of the sash 3, this fitting chamber is delimited on the outside by the side surfaces 2.1, 2.2 of the element frame 2 and on the inside by the side surfaces 3.1, 3.2 of the sash 3. In particular, a first guide rail 5 is provided between the side surface 2.1 of the element frame 2 and the side surface 3.1 of the wing 3 and a second guide rail 5 between the side surface 2.2 of the element frame 2 and the side surface 3.2 of the wing 3, so that the wing 3 is in the element frame 2 on both sides to be led.

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 leadership contours are also fundamentally conceivable.

In these guide rails 5, guide elements in the form of sliding carriages 6 are provided, which are guided in the respective guide rails 5 so as to be displaceable in the displacement direction VR. Other types of guide elements are also fundamentally conceivable. The sliding carriages 6 can each preferably be accommodated in a form-fitting manner in the respective guide rail 5. These sliding carriages 6 are at least indirectly connected to the parking scissors 7 and these in turn to the wing 3. As a result, the wing 3 can be moved in the vertical direction by means of the sliding carriage 6 guided in the guide rails 5, as shown in FIG Figures 2b and 2c is shown.

To limit the displacement movement of the wing 3 upwards or downwards, stops 5.1, 5.2 are provided. For example, the upper stop 5.1 limits the upward displacement of the wing 3 and the lower stop 5.2 limits the downward displacement of the wing 3. The stops 5.1, 5.2 can be designed, for example, as rubber buffers. These stops 5.1, 5.2 can in particular form boundaries for the sliding carriages 6, i.e. the upper sliding carriages 6 run onto upper stops 5.1 and the lower sliding carriages 6 run onto lower stops 5.2.

Figure 3 shows the vertical sliding element 1 and its fitting in a perspective detail view in a greater degree of detail.

The sliding carriages 6 are provided on a support rod 8.

A support rod 8 is assigned to each of the guide rails 5 provided on both opposite sides of the wing 3. The support rod 8 can be made, for example, from a flat material. It preferably runs parallel or essentially parallel to the guide rail 5. The sliding carriages 6 are arranged on this support rod 8 either directly or indirectly via sliding carriage carrier 6.1. The support rod 8 is thus slidably guided on the guide rail 5 together with the sliding carriage 6 provided thereon.

Like this in particular Figure 3 As can be seen, the storage scissors 7 are, on the one hand, articulated to the support rod 8 and, on the other hand, articulated to the wing 3.

The storage scissors 7 each comprise at least two scissor legs 7.1, 7.2, namely at least one long scissor leg 7.1 and a short scissor leg 7.2. The long scissor leg 7.1 is pivotally connected to the support rod 8 at a first free end and has a wing fastening element 7.3 at a second free end opposite the first free end, by means of which the long scissor leg 7.1 is connected to the wing 3. The long scissor leg 7.1 is pivotally connected to the wing fastening element 7.3.

The short scissor leg 7.2 is connected to the long scissor leg 7.1 in an articulated manner at a first free end in a central region, ie an articulation point connecting the scissor legs 7.1, 7.2 lies between the free ends of the long scissor leg 7.1. At a second free end, the short scissor leg 7.2 is at least indirectly connected to the support rod 8 in a pivoted and displaceable manner. The displaceability of the short scissor leg 7.2 relative to the support rod 8 can in particular can be achieved through an elongated hole 8.1, which is provided in the support rod 8. The short scissor leg 7.2 can either engage directly into this elongated hole 8.1 through a bolt-shaped connecting element or the short scissor leg 7.2 can be coupled to the support rod 8, as in Figure 3 shown, via a sliding carriage carrier 6.1. In particular, the sliding carriage carrier 6.1 can be slidably guided in the elongated hole 8.1 of the support rod 8 and connected to the short scissor leg 7.2 via a bolt-shaped connecting means. This allows a space-saving arrangement of the scissors 7 in the fitting, particularly in the closed position of the sash 3, to be achieved.

The arrangement of the scissor legs 7.1, 7.2 of the storage scissors 7 can be such that they are accommodated in the fitting chamber in the closed position with their longitudinal axis aligned vertically or essentially vertically. When moving the wing 3 into the in Figure 3 In the partially open position shown, the scissor legs 7.1, 7.2 are pivoted relative to one another in such a way that the long scissor leg 7.1 runs obliquely to the vertical at an acute angle, this angle opening upwards and the short scissor leg 7.2 runs obliquely to the vertical at an acute angle, whereby this angle opens downwards.

The scissor legs 7.1, 7.2 can be cranked at least in sections in order to enable the legs 7.1, 7.2 to be pivoted into a pivoting position in which the scissor legs 7.1, 7.2 and the support rod 8 run parallel or substantially parallel.

The Figures 4a, 4b show the locking mechanism by means of which the wing 3 is fixed in the closed position relative to the element frame 2. There are wing-side locking means on the wing 3 provided, which are formed, for example, by a drive rod 11 which can be displaced in the vertical direction and on which locking bolts 11.1 are provided. The drive rod 11 can be moved in a manner known per se by an actuating element, for example by a rotatable or foldable handle element.

The locking blocks 12, which interact with the locking bolts 11.1, are provided on the support rods 8 and are therefore moved along with the support rods 8 when the wing 3 is vertically displaced. The wing 3 is therefore not locked directly in relation to the locking blocks 12 provided on the element frame 2, but indirectly in relation to this element frame 2, namely via the support rod 8, which in turn is held displaceably in the guide rails 5 provided on the element frame 2. This means that when the wing 3 is in the closed position, it is secured against parallel parking via the locking means. The displacement of the wing 3 in the vertical direction is prevented by the positive engagement of the wing 3 in the opening provided on the element frame 2 or the upper stop 5.1.

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

Figures 5 to 8 each show horizontal sectional views through a facade element 20, whereby the Figures 5 , 7 and 8th the closed position and Figure 6 show the open position of the wing 3.

In the exemplary embodiment shown, the element frame 2 is arranged laterally next to a surface element 22 (not shown), for example a fixed glazing, and is formed at least in sections by the facade element frame 21. To separate the surface element 22 from the wing 3, a fighter 23 is provided, which forms a further section of the element frame 2. The element frame 2 or the facade element frame 21 is formed from composite profiles, in particular aluminum composite profiles, which consist, for example, of an inner and an outer profile, which are arranged at a distance from one another by a thermal separation. The composite profiles have a profile depth T in the range between 170mm and 250mm, in particular 190mm to 220mm, particularly preferably 200mm. In particular, the inner profile (profile section 2.3 that projects inwards from the thermal separation) of the composite profile has a profile depth in the range between 100mm and 150mm, in particular between 120mm and 140mm. Due to such a large profile depth T, it is possible for the wing 3 to be flush on the inside in the open position.

The fitting which enables the parking movement and vertical displacement of the sash 3 is, as previously stated, formed from a pair of guide rails 5 which are provided on opposite side surfaces 2.1, 2.2 of the element frame 2. These guide rails 5 are integrated into spaces 4, which are formed in the closed position of the wing 3 between the side surfaces 2.1, 2.2 of the element frame 2 and the opposite side surfaces 3.1, 3.2 of the wing 3. In other words, in the closed position of the sash 3, the side surfaces 2.1, 2.2 of the element frame 2, which are opposite at the same height, and the side surfaces 3.1, 3.2 of the sash 3 delimit a fitting chamber into which the guide rails 5 are integrated.

The guide rails 5 have a depth that is essentially equal to the depth of the fittings chamber, which is spatially limited in the closed position. In particular, the depth t of the guide rails 5 is significantly less than the depth T of the profile section 2.3 projecting inwards from the thermal separation. As a result, the guide rails 5 cannot be accommodated in the fitting chamber visibly from the front in the closed position.

Like in particular Figures 5 and 5a To see, the storage scissors 7 are designed in such a way that the scissor legs 7.1, 7.2 are accommodated in the fitting chamber in the closed position of the sash 3 with their longitudinal axes aligned vertically between the guide rail 5 and the side surfaces 3.1, 3.2 of the sash 3.

Like in particular Figure 6 can be seen, the wing 3 has a wing depth FT, which is equal to or less than half the depth ET of the element frame 2, in particular in the area of the profile area 2.3 (FT ≤ ET / 2). This can ensure that the wing 3 is externally flush or essentially externally flush with the element frame 2 in the closed state and internally flush with the inside of the element frame 2 in the open state. In other words, the opening movement required to open the sash 3 takes place completely within the element frame 2, ie in the open state the sash 3 does not protrude from the plane spanned by the inside of the element frame 2.

In order to be able to optically conceal the guide rails 5, sliding carriage 6 and opening scissors 7 in the closed position, the wing 2 has blind sections 3.3 on the inside. These blind sections 3.3 protrude laterally from the inside of the wing in the horizontal direction and thereby at least partially close the space between the element frame 2 and the wing 3 (limited by the side surfaces 2.1, 2.2, 3.1, 3.2), in which the guide rails 5, sliding carriages 6 and opening scissors 7 are provided. The blind sections 3.3 are preferably dimensioned such that in the closed position there is a circumferential shadow groove, for example a shadow groove in the range of 2 to 6 mm, in particular 4 mm. This will, for example, in Fig. 5, 5a visible, a visually inconspicuous integration of the fittings is achieved.

Figure 6 shows an example of a horizontal sectional view through a facade element 20 in an area below the opening that can be closed by the wing 3 and with a wing 3 in the open position. The element frame 2 is filled in this area by a facade element section 24. A chamber 13 is formed on the inside in front of the facade element section 24, which is closed in the direction of the interior I by a panel 13.1. The panel 13.1 can in particular be a removable panel. This makes it possible to remove the cover 13.1 when assembling 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.

Shadow grooves 13.2 are provided between the panel 13.1 and the profile sections 2.3, through which the scissor legs 7.1, 7.2 can be passed. In particular, the scissor legs 7.1, 7.2 are positioned above the shadow grooves 13.2 when the sash 3 is opened, so that when the sash 3 is moved vertically, the scissor legs 7.1, 7.2 can be inserted into the shadow grooves 13.2 from above.

Analogous to the chamber 13, a chamber 14 can also be provided above the opening closed by the wing 3 in the closed position, which can also be closed, for example, by a removable panel 14.1. This means that a space accessible from the inside can also be created above this opening, which can be used for maintenance and installation work but also to accommodate other functional elements.

As previously stated, the vertical sliding element has a locking mechanism in which locking bolts 11.1 arranged on a drive rod 11 provided on the wing side interact with locking blocks 12 arranged on the support rods 8.

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

As in Figures 2a to 2c shown, the wing 3 can be in operative connection with means through which the weight of the wing 3 is balanced. In particular, the weight compensation can serve to brake the wing 3 when opening in order to prevent the wing 3 from accelerating too much during the vertical downward displacement movement and hitting the stop 5.2 undesirably hard. In the opposite way, the weight compensation can ensure that when the wing 3 is closed, it is moved upwards with the support of the weight compensation, so that a person operating the wing 3 does not have to lift the entire weight of the wing 3. In addition, the weight compensation ensures that the wing can be positioned in a desired sliding position, ie for example in a partially open position, without the wing 3 always moving further into the fully open position due to gravity. In other words, the weight compensation can form a weight element that compensates for the gravitational force of the wing 3.

The weight compensation can be implemented 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 chosen in particular to be slightly lighter than the weight of the sash 3. The counterweight 15 can, for example, be displaceable in the frame profile of the element frame 2, in particular in the profile section 2.3 be integrated. The counterweight 15 is there, as in Fig. 8 shown, coupled to the wing 3 via a connecting means 15.1, for example a rope, via at least one deflection roller 15.2. This can ensure that when the sash 3 is opened, the counterweight 15 is raised by a vertical downward displacement movement and thereby counteracts the force of gravity acting on the sash 3, in order to then support the closing movement when the sash 3 is closed by lowering the counterweight 15 .

In order to prevent the counterweight 5 from falling unbraked onto the bottom of the element frame 2 when the connecting means 15.1 is torn off, a damping element, for example a damping element containing a spring, can be provided in the element frame 2, which in this case cushions 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 an inspection opening in the area of the damping element, which can be closed, for example, by a cover.

In the exemplary embodiment shown, the counterweight 15 is slidably guided on a guide element 16, which is provided inside the profile section 2.3. The guide element 16 can in particular be 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.

The connecting means 15.1 preferably establish a connection between the counterweight 15 and a support rod 8. This can ensure that the connecting means 15.1 do not experience any deflection due to the parallel parking of the wing 3 in the direction of the inner region I.

In order to achieve the most distortion-free suspension of the wing 3, each of the two support rods 8 is preferably coupled to the counterweight 15 via connecting means 15.1 and corresponding deflection rollers 15.2. A connecting means 15.1 preferably spans the narrow side of the opening formed in the element frame on the top side and closed by the cover 14.1 in order to be coupled to the support rod 8 located away from the counterweight 15.

Figures 9a, 9b and 10a, 10b show the fitting parts used for the displacement and parallel parking movement of the sash 3, the guide rails 5 not being shown in the figures for reasons of clarity.

The fitting of the vertical sliding element 1 includes, in addition to the pair of guide rails 5 that can be attached to the element frame 2, a pair of support rods 8. There are preferably over Sliding carriage carrier 6.1 fastens the sliding carriage 6. Furthermore, a pair of parking scissors 7 are provided on the support rods 8, which are opened for parallel parking of the sash 3 ( Fig. 9a , Fig.10a ) or closed ( Fig. 9b , Fig.10b ) can be.

As previously described, the support rods 8 have elongated holes 8.1, through which the parking scissors 7 can be opened or closed. In the exemplary embodiment shown, a free end of the short scissor leg 7.2 is pivotally connected to the sliding carriage carrier 6.1. This sliding carriage carrier 6.1 is in turn guided displaceably in the elongated hole 8.1 in the area of the free end opposite the short scissor leg 7.2. By moving the sliding carriage carrier 6.1 in the elongated hole 8.1, the position of the free end of the short scissor leg 7.2 is changed and thus the opening or closing of the parking scissors 7 is effected.

The support rod 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 scissor leg 7.1 can be received in the closed position of the wing 3, namely an upper section of the long scissor leg 7.1, on which the wing fastening element 7.3 is provided.

In addition, the long scissor leg 7.1 can be cranked, so that in the closed position of the storage scissors 7, the upper section of the long scissor leg 7.1 comes to rest in the plane spanned by the support rod 8. This allows, as particularly in Figure 9 B can be seen, an extremely space-saving arrangement of the fitting in the fitting chamber can be achieved.

Like in particular Figures 10a and 10b As can be seen, in the upper area of the support rods 8, the connecting means 15.1 are connected to the respective support rod 8 via coupling points 17. In particular, cable tensioners having a thread can be provided at the coupling points 17. The thread of the cable tensioner can be screwed into a thread provided on the support rod 8. As a result, a length adjustment or adjustability of the weight compensation of the wing 3 can be achieved.

The support rods 8 and the scissors 7 can be made of metal, in particular stainless steel.

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

In the area of the connecting means 15.1, a cover element 18 is provided on both sides of the wing 3. This cover element 18 projects upwards in the vertical direction and covers the connecting means 15.1 at least in the direction of the interior area I, so that they are no longer visible from the interior area I. The cover element 18 is preferably designed as a U-profile, which is open towards the element frame 2. As a result, the cover element 18 can be installed in a technically simple manner and surrounds the connecting means 15.1 on three sides, so that it is completely covered.

The cover element 18 is preferably moved in the vertical direction with the wing 3 or the support rods 8.

Figures 11a, 11b and 12 show a sensor system 30, which is provided for checking the closed state of the vertical sliding element 1. The sensor system 30 includes 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, ie a sensor system that can check the closed state of the vertical sliding element 1 based on 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. This sensor can in particular be designed to provide information as to whether or how close the magnet is to the sensor. In the exemplary embodiment shown, the first sensor system part 31 includes the magnet and the second sensor system part 31 includes the sensor.

Preferably, the first sensor system part 31 is provided on the wing 3 of the vertical sliding element 1 and the second sensor system part 32 on the element frame 2. In the exemplary embodiment shown, the sensor system 30 is provided in an upper chamber between the wing 3 and an upper, horizontally extending profile section of the element frame 2, namely hidden behind the blind section 3.3 of the wing 3 or a blind section 2.4 of the element frame 2 ( Fig. 11a, 11b ). This makes it possible to achieve a visually inconspicuous integration of the sensor system 30 into the vertical sliding element 1. It goes without saying that other arrangement options are also fundamentally conceivable.

The sensor system 30 is preferably designed or arranged in such a way that the closed position is only detected when Not only is the wing 3 in the closed position, but the wing 3 is also locked. For this purpose, for example, a sensor system part 31, 32, in the exemplary embodiment shown the first sensor system part 31, is coupled to the drive rod 11. In the exemplary embodiment shown, this coupling is realized by means of an angle element 33. Other coupling means are also fundamentally conceivable. As a result, the first sensor system part 31 can be arranged in the upper chamber between the wing 3 and the upper, horizontally extending profile section of the element frame 2 and at the same time be coupled to the moving drive rod 11.

Fig. 11a shows the arrangement of the two sensor system parts 31, 32 relative to one another in the closed position of the wing 3 in the unlocked state. Fig. 11b On the other hand, the arrangement of the two sensor system parts 31, 32 relative to one another shows the closed position of the wing 3 in the locked state.

If the unlocked wing 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 by the sensor system 30 or the signal is characteristic of the unlocked state. If the wing 3 is locked, the drive 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 wing 3 is emitted by the latter.

The sensor system 30 is preferably coupled to a building-side lock monitoring device. This can, for example, be centrally located in the building, divided into floors or other sections. This means that you can use the to Vertical sliding elements 1 provided sensor systems 30 central and complete locking monitoring of a large number of wings 3 can be achieved.

The invention has been described above using exemplary embodiments. It is understood that numerous changes and modifications are possible insofar as they fall within the scope of the appended claims.
