Description

Vertical sliding window for a building

The invention is directed to a vertical sliding window as a closure for an opening in an outer wall of a building, wherein all superposed, movable windows of the sliding window are part of a single sliding sash, which can be lowered to open as a whole vertically down and thereby wholly or predominantly in a shallow chamber is retractable inside a box.

In conventional swing-wing windows, the open swing wings protrude disturbing into the space in question, which restricts the local freedom of movement uncomfortable. It has therefore already been considered to design a window sash in its plane vertically displaceable. In particular, it is already proposed in US Pat. No. 2,525,322 to use a window with two wings in a window opening, which windows are located one above the other in the closed state of the window. The lower wing can then be pushed vertically if necessary, until it comes to about with the upper wing to cover. The window is then opened in its lower half, without a wing protruding into the room in question. However, the created opening is only about half as large as the wall opening between the lintel and windowsill, which is not sufficient in some situations. Finally, the always visible lower edge of the two window sashes is visually distracting, since it passes through the clear or transparent region of the actual window panes.

By the construction used by the invention, a window can be opened without affecting the freedom of movement space inside a room. Consequently, there is the possibility, in the case of a body-friendly outside temperature - ie in warmer latitudes

CONFIRMATION COPY and / or during the warm season or in the transitional period - leaving a window open for an extended period of time so that the space in question is always well ventilated. However, it has become known that extensive ventilation does not always bring benefits for the room in question. Because in the air there are always suspended particles whose amount and composition varies according to the environment, year and time of day and weather. This ranges from desert sand, which can reach anywhere under certain weather conditions, for example, from the Sahara to Central Europe, road dust, pollen and other allergens to various aerosols, soot blast furnace emissions and from the most diverse combustion processes and other fine dust. If these substances penetrate into the living area, then they can cause a variety of negative effects there: While sand and dust settle "only" on the furniture and form a layer of dust that can be removed only with great effort, are pollen and others Allergens are far more unpleasant for a large part of the population and can trigger not only cough and rash but also asthma, not to mention soot and other particulate matter, which is respirable and accumulates and in the worst case can even be carcinogenic.Furthermore, suspended particles can also be chemical transporting irritating or even toxic substances and even even radioactive substances and transporting them into the lungs, where they can then develop their harmful effects, with constellations typical for the particular composition of the suspended particles, for example in conurbations n, high admissions, especially soot and other particulate matter to be found; On the other hand, in the countryside, that is, far from metropolitan areas, pollen can be found in fertile areas, and in arid areas more like sand and dust. From the disadvantages of the prior art described results in the invention initiating problem, a generic, vertical sliding window in such a way that when opening the window On the one hand, the open casement does not protrude into the room, so that at moderate outdoor temperatures, a continuous ventilation is possible, while the possibility should be created to protect the space in question from the excessive penetration of suspended particles.

The solution to this problem is achieved by the fact that at the upper edge of the sliding leaf, the free lower edge of a filter mat is mounted or suspended, which is suitable for filtering suspended particles such as fine sand, dust, soot, aerosols, allergens or fine dust and of a shaft installed above the closed sliding sash can be unwound.

The chamber for receiving the lowered window sash is located in a designated box below the actual window, so below a windowsill, if there is a windowsill. This chamber is preferably closed on the shell side, except for a narrow slot at its top, through which the relevant window can be pushed upwards out of the chamber or can be lowered down into the relevant chamber. The walls of this chamber may be made of plastic or metal, in particular sheet metal. By the slot is sealed at the upper end of the chamber opposite the more or less immersed in that disc, for example. By a respective sealing strip made of rubber od. Like. Soft material, there is no access for suspended matter in this area. These can thus penetrate at best through the left of the completely or partially lowered window opening in the space in question. In order to prevent the ingress of suspended matter here, the possibility is opened according to the invention to close the window opening above the disc upper edge with a filter mat. This is such that an exchange of air is possible, but suspended matter is retained as far as possible. It should be noted that the different floating particles have different size dimensions. While grains of sand can have a diameter of about 1 mm, are Dust particles much smaller. Pollen typically have dimensions between 10 pm to 100 pm, and particulate matter has even smaller dimensions, usually below 5 pm, within the nanometer range. It is not necessary for every application to filter all floating particles. As indicated above, it is also necessary to focus on the location of use of the relevant window, with arid areas of fertile areas and even agglomerations to be distinguished. In the first case, a filter should be able to retain suspended particles of a size of 100 pm or above; In fertile areas, suspended particles of 10 pm mm to 100 pm should also be retained, and in urban areas also, if possible, suspended particles of less than 10 pm mm, for example down to 1 pm or even below. In the context of the invention, therefore, various embodiments can be offered, which differ in the nature of the filter mat from each other. It is preferably a very fine-meshed fabric with a mesh size of less than 1 mm, for example with a mesh of 500 microns or less, or of 200 pm or less, preferably with a mesh of 100 microns or less, for example with a mesh size of 50 μm or less, or 20 μm or less, or even with a mesh of 10 μm or less. In order to improve the filtering effect, the fabric, which preferably consists of synthetic fibers, for example polyester or nylon fibers, or of glass filaments, in particular individual glass filaments, may be roughened on at least one side and / or provided with a coating to prevent the adhesion of To improve suspended particles. In order to improve the transparency despite the fine mesh, it may further be provided that the intersecting threads have a different mesh size in one direction than in a direction transverse thereto, for example in one direction more than twice the mesh width than in a direction transverse thereto, or in one direction at least three times the mesh size, or in one direction at least four times the mesh size. In this case, the clear cross section is increased while the mesh size at least in one direction is sufficiently small to retain even small floating particles. For the filtering of particulate matter or soot additional measures may be provided, for example. The arrangement of two or more such fabric mats parallel to each other in direct contact, wherein preferably the orientation of the threads of two fabric mats may be rotated by 45 ° from each other, or at three fabric mats + 30 °, based on a middle fabric mat.

The invention further provides that adjacent to the free lower edge of the filter mat two straight, preferably mutually parallel longitudinal edges of the filter mat web, which connect the free lower edge of the filter mat with the shaft and run in each ener lateral guide and / or seal. In this case, a guide primarily has the task to keep the unwound filter mat at wind position at its intended position, while it is the responsibility of the seal to seal the filter mat against the inside of the window frame to prevent the penetration of suspended particles there.

For this purpose, it has been proven that the lateral guide and / or seal for the filter mat has a U-shaped cross section, the opening of the filter mat faces. Preferably, the unwound filter mat engages the edge in this opening and learns in their leadership.

The guide and the seal can be integrated with each other so that one or both inner sides of the opening of a lateral guide is provided with a rubber seal or with a brush seal.

The invention can be further developed such that at the upper edge of the sliding sash, the free lower edge of a fly screen or a horizontal rod fixed thereto is hung or suspended, the fly screen being unwound from a shaft installed above the closed sash. The filter mat on the one hand holds off suspended particles, However, due to its fine mesh, it also limits the air flow rate and can possibly also impair visibility to the outside. If, under certain circumstances, these considerations outweigh the retention of suspended particles, but nevertheless the ingress of pests is to be avoided, a fly screen can be used instead of the filter mat and hung on the upper edge of the lowerable pane. A fly screen is clearly coarser mesh than a filter mat according to the invention; while a filter mat according to the invention has a clear mesh size of less than 1 mm, for example a mesh size of 500 pm or below or 200 pm or less, preferably a mesh size of 100 pm or less, for example a mesh aperture of 50 pm or below or of 20 pm or below, or even a clear mesh size of 10 pm or less, a fly screen according to the invention should have a mesh size of at least 1 mm or above, preferably a mesh size of 1, 2 mm or above, in particular a mesh size of 1, 4 mm or above, to ensure adequate air flow and transparency.

It is within the scope of the invention that within an upper, horizontal end element at least one shaft is supported, of which the filter mat and / or the fly screen is unwound, preferably a filter mat and / or the fly screen receiving shaft by a spring element in such Direction is biased that it endeavors to wind up the filter mat and / or the fly screen.

The shaft (s) should be displaced in a direction perpendicular to the plane of the window, so that a separate filter mat for a thin filter mat are provided in addition to lateral guides for the unevenly thicker window.

If the free end of the filter mat and / or the fly screen in a window pane facing area of the respective wave triggers, so it may already there with the guide provided near the guide for the window window into engagement, so that a further deflection of the filter mat or the fly screen is not required. The invention is further characterized by a first shaft for the filter mat and a second shaft for the fly screen. By winding on two separate waves, the filter mat on the one hand and the fly screen on the other hand can be independently handled and used. It is therefore possible to use only the filter mat alone, or only the fly screen alone, or both at the same time.

Further advantages result from the fact that the filter mat is wound onto the first shaft in an opposite sense of winding than the fly screen on the second shaft. This makes it possible to arrange the two shafts on opposite sides of the window, so once outside of the same, the other times on the inside.

If a window according to the invention is equipped both with a filter mat and with a fly screen, it is advisable to arrange the screen on the inside of the filter mat. As a result, on the one hand there is the possibility that when used at the same time, the generally firmer fly screen can additionally support the filter mat in relation to the wind pressure; In addition, the filter mat can then be automatically cleaned in a rain by washing away adhering particles.

Furthermore, there is the possibility that for cleaning purposes the shaft with the filter mat and / or the shaft with the fly screen can be removed, and / or that the filter mat and / or the fly screen can be removed from its respective shaft. In the latter case, the filter or grid web in question can even be washed in a washing machine. When a spring biasing member for the first shaft is disposed opposite to the spring member for the second shaft in a reverse sense of rotation, an arrangement is supported wherein the two shafts are on different sides of the windowpane.

A preferred design rule states that lateral guides for the fly screen are arranged on the side facing the interior of the guides for the filter mat. This corresponds to the arrangement explained above, wherein an internal fly screen can support the filter mat against an externally charged wind pressure. On the other hand, u.U. Also, a reverse arrangement can be selected, in which case the filter mat is located on the side facing the interior of the fly screen. The invention preferably features an arrangement in which the free lower edge of the filter mat or a horizontal bar fixed thereto is suspended or suspendable in the region of the outside or in the region of the inside of the upper edge of the sliding leaf. If an additional fly screen is not provided, the filter mat can be hung on both sides of the sliding sash, ie on the outside or on the inside.

If, on the other hand, a fly screen is provided, then the free lower edge of the fly screen or a horizontal bar fixed thereto should preferably be hung or suspended in the area of the inside of the upper edge of the sliding leaf. The filter mat then finds its place preferably on the outside of the sliding sash.

By all superimposed, movable windows of the sliding window are part of a single sliding leaf, which is lowered to open as a whole vertically down, eliminating the need to otherwise be provided between several sliding sash seal. It is much easier to seal a single sliding leaf against a fixed frame, both against driving rain and against drafts, as several, relative to each other and relative to a frame movable sliding sash. In addition, simplifies the leadership and possibly the drive mechanism.

In this case, a purely vertical sliding movement of the sliding leaf is preferred, ie without any tilting or Ausstellbewegung. The arrangement according to the invention thus favors the use of only a single sash within an entire sash; a division of the entire glass surface in several casements is not required. Accordingly, it is possible to completely dispense with horizontally extending fighters or vertically extending setting woods. At most, in oversized, for example, particularly wide windows, especially at widths of 1, 50 m or more, a division into several sliding sash can be done, for example by means of interposed jibs.

As a lowerable window pane, the most diverse types of flat glass come into consideration: float glass and / or glass with special properties such as toughened safety glass or teilvorgespanntes glass, and / or glass with a special structure such as laminated glass and laminated safety glass, multi-pane insulating glass or wired glass, and / or windows with special coatings such as self-cleaning glass, sunscreen glass, or smart glass. Here, glasses with different properties can be assembled into glass sheets with different structures and completed into windows with different coatings. A usable in the context of the invention, standard flat glass is, for example, float glass, which is produced in the float process, resulting in particularly smooth surfaces. In addition, single-pane safety glass (ESG), which is thermally prestressed, can also be used for the invention. In the latter case, due to an inhomogeneous cooling process in the faster cooled surface compressive stresses and in the slower cooled interior of the glass tensile stresses. The compressive stresses on the surface complicate the formation and propagation of cracks, with the result that strength and thermal shock resistance of ESG are significantly better than the corresponding properties of a comparable, but not thermally treated flat glass.

Also partially tempered glass (TVG) is suitable for the present invention; this is also thermally toughened, but the thermal prestress during manufacture is weaker than in ESG.

Furthermore, the invention can also be realized by means of laminated safety glass (LSG), which consists of alternating layers of glass and plastic film. This type of glass is based on the idea that in the event of a break, the glass fragments or fragments will adhere to the foil (s). Laminated safety glass may consist of combinations of different types of glass, e.g. made of float glass, ESG and / or TVG.

So-called. Laminated glass would also be usable; this consists of at least two panes and organic intermediate materials such as cast resin.

The multi-pane insulating glass (MIG) which can likewise be used in the present invention comprises at least two panes and an edge composite with a pane gap which can be filled with gas or air. If two glass panes with different thicknesses are used, such a multi-pane arrangement has very good sound-insulating properties. In the context of the invention, wire glass can also be used, that is to say a glass in which a wire mesh is inserted into the shaped glass strip during shaping by the rollers, which gives the pane in question penetration-resistant properties and thus makes them almost burglar-proof.

Also, windows with self-cleaning properties can be used. These may be equipped on their outer side with a self-cleaning coating, for example with a coating according to the so-called lotus effect.

In addition, other types of glass, in particular soundproof glass, safety glass, as well as coated glasses of all kinds are suitable. The window panes according to the invention can also be combined with a sunscreen, in particular by using a sun protection glass which is provided at least in regions with an absorbing and / or reflective coating , in particular on the respective outer side.

Finally, there are now so-called. Intelligent glass, ie, electrically switchable glass, the light transmission can be changed by the application of a voltage. In such an arrangement, the use of a shutter or a blind is dispensable. The coating itself can be switched in the manner of a liquid crystal display either between transparent or bright on the one hand and opaque or dark on the other hand. In principle, a glass with such a coating can also be integrated with the invention to form a product. It has proved to be favorable that the at least one lowerable window pane has a displaceable frame connected to the glass pane (s) or is frameless. A frame can especially in glass or window panes made up of several layers, such as laminated glass, laminated safety glass or multi-pane insulating glass, serving to stably connect them to one another.

In this case, the free lower edge of a fly screen can be mounted or suspended on the upper edge of the sliding leaf, which can be unwound from a roll installed above the closed sliding leaf. Such an arrangement has the advantage that in the suspended state, the fly screen is just as far pulled out, as is required to close the created by opening the window glass opening for insects impenetrable, the free view through the closed or not completely open Slice through is clearly preserved. So if the sliding leaf is moved - whether manual, mechanical or motor - then the fly screen always follows this movement and closes the respective free space above the lowerable sash.

The hanging of the fly screen on the sliding sash can preferably take place over the entire width of the window sash, so for example by means of interlocking, horizontal, undercut profiles, so that at this point no gap remains, through which insects could enter a room. Such a purely mechanical form of hanging is the simplest and safest. Nevertheless, of course, other compounds would also be considered, e.g. by magnetic force, by a magnetic strip or a magnetic strip is arranged on an element, for example. On an end rail of a fly screen, which cooperates with a preferably ferromagnetic strip on the other element, for example. At the upper edge of the sliding leaf, and yet is solvable at any time , simply by pulling the two elements apart.

The invention undergoes an advantageous development to the effect that in the upper region of the guide frame a roller is mounted, of which the Fly screen is developable. Thus, this role as well as the fly screen wound thereon is also part of the installation unit according to the invention, which considerably simplifies or facilitates the assembly. The role of the screen receiving roll should be biased by a spring element in such a direction of rotation that it endeavors to wind the screen. As a result, on the one hand, the fly screen is always held under tension and wound up automatically when closing the window.

According to the idea of the invention, a (preferably further) roller can be mounted in the upper area of the guide frame, from which a roller shutter, a roller blind or a blind can be unwound. This also a shading device for the window is integrated into the assembly according to the invention and therefore does not need to be retrofitted on site.

Another design rule states that in the two lateral sections of the guide frame at least one guide groove for leading each receiving a side edge of the shutter, blinds or the blind is incorporated, the slot-shaped openings of the two guide grooves in a common, vertical, to the vertical plane Sliding windows are parallel plane and face each other. This ensures that a flat shading means is guided along its two side edges parallel to the window pane.

The lateral guide grooves for a roller shutter can be located on the outside of the retractable window pane (s). In this case, the closed, stable roller shutter outside the window is in front of that and thus forms an additional burglary protection.

Furthermore, there is the possibility that the lateral guide grooves for a roller blind or a blind on the inside of the retractable Window pane (s) are located. Those rather fragile shading devices are less suitable as burglary protection and can in turn be protected by the window pane according to the invention against external influences such as wind, rain, snow or hail.

Furthermore, it is the teachings of the invention that in the upper region of the window opening, preferably on the outside, a diaphragm made of a transparent material is provided to allow a schlagregensichere night ventilation.

If the box receiving the lowered sliding window is not transparent, at most an upper edge strip is visible from the completely lowered window pane, and therefore can not be damaged. Because a stable box made of a hard plastic or even a metal offers the lowered window optimal mechanical protection against damage. Ultimately, this box can be used on top of that in a masonry and is in turn surrounded by that protective, especially on its two flat sides.

The invention can be further developed in such a way that the box accommodating the lowered sliding window can be connected, connected or integrated with an upper guide frame which receives the closed sliding window. By a firm union of these elements can be ensured that a glass sheet always finds straight stretched and aligned guideways during their lowering and thus can neither break nor cant.

In the two lateral sections of the guide frame, at least one respective guide groove for leading reception of each side edge of the lowerable window pane can be incorporated, wherein the slot-shaped openings of these two guide grooves in a common, vertical, to Plane of the vertical sliding window parallel plane and face each other. The width of these slots depends on whether the sliding window is in a frame or not. In the former case, the slot width must correspond to the frame thickness, in the latter case only the total thickness of the displaceable window pane itself and possibly a sealing profile provided for sealing.

Preferably, in the region of slot-shaped openings, in which / through which the window pane and / or its frame slides, seals are provided on the inside and / or outside of the window pane or frame in order to prevent the ingress of water, drafts, or the like prevent. Such seals preferably extend in the longitudinal direction of the respective slot section and may be located in the region of the respective outer edge of the slot or be displaced into it. The sealing lips of these fixed to the slot-shaped openings seals are preferably on the window or its frame; Preferably, the cross section through such a sealing lip is not perpendicular to the respective window pane or frame surface, but obliquely thereto or is pressed by an inherent elasticity to the surface in question, wherein the sealing lip in its cross section, if necessary, tangential to the relevant Surface can bend. Depending on whether outside the building wind or gusts occur, the pressure conditions may be different - on a side of the house facing the wind, the external pressure may be stronger than the internal pressure, on a side facing away from the wind due to suction effects less. For this reason, two seals - one outside the window pane and one inside the building - complement each other, whereby, for example, each of the overpressure-facing seal is pressed against the window pane or its frame and thus the sealing effect is improved even with a positive pressure. The invention recommends that the box receiving the lowered sliding window has a further, flat chamber for receiving insulation, in particular thermal and / or acoustic insulation. This measure makes it possible to compensate for the reduced insulation capacity of the chamber itself by an additional insulation layer parallel to the window plane. As insulation are simple materials such as mineral wool into consideration, but also polystyrene or so-called vacuum insulation panels. Preferably, the insulating layer is located on that flat side of the chamber, which faces the outside of the building; However, this could be different in certain cases, or an insulation could be completely eliminated, for example, in buildings or in countries near the equator.

Due to the lowering movement of the window pane downwards, the counterweights which are usually present when the sliding panels are to be lifted upward into the open position are dispensable. This reduces the effort on the one hand; On the other hand, space is also saved, especially within the chamber according to the invention, in which now no counterweights are to be accommodated, although of course such a measure would be additionally possible. However, these counterweights would have to be raised in the invention to open the sash, and lowered when closing it.

If - as the invention continues to provide - such counterweights would still be provided and heavier, especially slightly heavier than the sliding sash with glass panes would be those - for example, after release of a lock - close the sliding panel automatically, even without auxiliary power. It could then be provided a lock to lock the open sliding sash until the lock - eg. By a timer - is released and then no longer prevents the counterweights to pull the window in its closed position. Such a timer could, for example, a preferably mechanical, wind-up and / or be similar to a time interval in another adjustable clock, for example, similar to a designated in another embodiment form as egg timer, from an initially set time interval, eg. "10 minutes" backward running timer, which then releases the lock on return to the zero time, and thus the counterweights can close the sliding sash so that any ventilation time can be set and after expiry of the relevant time interval the window closes automatically.

However, the invention preferred a development of the invention, wherein in the lowered sliding window receiving chamber of the box or in another, flat, to the first parallel chamber of the box a drive for lifting and / or lowering the lowerable window pane (s) is arranged. Such a mechanical drive ensures that the window pane is always raised or lowered at an approximately optimum speed. Although such a drive could be constructed purely mechanically, that is, for example, be manually operated, e.g. via a crank, or with the above-described counterweights, which, however, can give the sliding sash only one direction of movement; however, an activator operable with an auxiliary energy, e.g. a motor which is fed, for example, electrically, electronically, magnetically, pneumatically or hydraulically, or else a cylinder which can be activated pneumatically or hydraulically, etc.

Such a self-locking trained activator, so for example. A motor which is able to apply a sufficient braking torque at standstill, can then fully replace counterweights, which in the chamber further space for mechanical transmission elements of the drive device od. Like. Created. In contrast to the above-indicated, purely mechanical locking mechanism to close the sliding sash after an adjustable ventilation time again, a motor drive device has the advantage that it is mostly in both directions - ie shooting the sliding sash as well as opening the same - used and also can replace a mechanical brake. The window can then be closed or opened at any desired time via a controller. According to the invention, it can be provided that the drive has one, two or more vertical rack bars connected or connectable to the lowerable window pane (s). It can ever mesh a pinion with horizontally oriented axis of rotation, each with a rack to move by a common effort on all rack (s) the window pane with a total of moderate effort.

Optionally, the drive may comprise one or more vertical threaded spindle (s) connected or connectable to the lowerable window (s). It can ever comb a pinion with vertically oriented axis of rotation, each with a toothing at the lower end of a threaded spindle to move by a common effort on all threaded spindle (s) the window pane with a total of moderate torque. The invention can also be realized in such a way that the drive has one or more vertical tension elements (e) connected or connectable with the lowerable window pane (s). In this case, depending on a coil or drum, preferably with horizontally oriented axis of rotation, depending on a traction means either up or down to raise or lower the window pane with a total of moderate force by a common effort on all traction means.

For motor or automatic drive of the sliding leaf, at least one energy converter can be provided for converting a supplied auxiliary energy into a mechanical movement, for example an electric or hydraulic motor or a hydraulic or pneumatic cylinder. Furthermore, the drive of the sliding leaf can be coupled to a control, regulation and / or monitoring, which automatically causes closing or a partial or complete opening of the sliding leaf according to predefined criteria. For example. can be closed in a weather deterioration, especially in conjunction with wind, rain and / or cold, an initially open window. Also, as part of a central burglary protection system, the windows according to the invention could be closed when leaving and shutting off the building or living space in question. Furthermore, by means of a room monitoring, a lack of oxygen and / or increased humidity in the relevant interior could be ascertained, and then the sliding panel could be opened to a certain extent to allow an exchange of air, if necessary even for a predetermined period of time, to cool down of the relevant interior.

Further features, details, advantages and effects on the basis of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. 1 shows a sliding window according to the invention in a vertical section transversely to the plane of the pane, which is driven by way of example by a type of scissors linkage;

Fig. 2 is an enlargement of the detail II in Fig. 1; such as

Fig. 3 shows an alternative drive for the sliding window of FIG. 1 in a schematic representation in a viewing direction perpendicular to the window plane. An inventive sliding window 1 is intended to eliminate the disadvantages of conventional windows. For this purpose, several elements are connected to a unit. The central component is a window pane 2. This can also consist of several interconnected glass panes, for example of two or three panes of glass. Possibly. These may also be separated by one or more cavities, thereby improving the thermal and / or acoustic isolation capability.

Preferably, this window pane 2 or possibly the majority of glass panes, from which it consists, is held in a sliding frame 3. However, this is not mandatory. A single pane of glass or a window pane 2 consisting of interconnected panes of glass could also be used without directly connected frames.

The sliding frame 3 can be arranged completely around the circumference of the window pane 2, or only partially along running.

Preferably, an upper horizontal bar 4 of the sliding frame 3 extends along the upper edge 5 of the window pane 2 and / or a lower horizontal bar 6 of the frame 3 along the lower edge 7 of the window pane 2. These two horizontal bars 4, 6 can be connected to one another by lateral struts be, but this is not mandatory, as far as the (the) spars 4, 6 are otherwise attached to the window glass 2. The sliding frame 3 is particularly suitable as a point of attack for a manually or motor-driven sliding device. Without such a sliding frame also punctual, for example. Clamp-shaped receptacles for the window pane 2 on a motor-driven sliding device for introducing force into the window pane 2 suffice.

The entirety of the window pane 2 and all firmly connected parts 4, 6 of the sash 3 form the sliding sash 8. Of course, the Sliding frame 3 of the sliding sash 8 also have rungs that can be vorgeblendet either or actually divide the sash 3 into several areas or openings, in each of which a window pane 2 is inserted. However, such a measure would generally be less functional than intended for aesthetic reasons.

So that the sliding sash 8 is vertically displaceable, its side edges - ie in the absence of sliding frame 3, the side edges of the window pane 2, or in the case of an incomplete sliding frame 3, the front sides of the horizontal bars 4, 6, or in a complete sliding frame 3, the horizontal bars. 4 , 6 interconnecting vertical side wing woods or struts - height-slidably received in two lateral guide rails 9 of a window frame 0.

The window frame 10 surrounds the sliding sash 8 at its entire circumference. This can consist of any material and have any shapes and strengths. Illustrated by way of example are two lateral height legs, window posts or window frames 11, which accommodate the guide rails 9; these can be connected above and below the closed sliding leaf 8 by a respective cross brace. An upper leg or upper closure element 12 connects the two window posts 11 above the sliding leaf 8, while those lateral window posts 11 are connected by a weatherboard and / or a sill and / or a lower closure element 13 at a distance below the upper end element 12, which corresponds approximately to the height of the window pane 2.

Preferably, the lower end member 13 is not formed as a pure cross-wood, but may have a flat, preferably rectangular extension with a height corresponding to the height of the window pane 2. On the inner and / or outer flat side can be provided with a support plate for plaster 52 or with another, plate-shaped facade material or with a visible surface, a flat formed end element 13.

This closing element 13 accommodates a chamber-like cavity 14. This extends over the entire or almost the entire height of the lower end element 13, its width corresponds to the distance between the guide rails 9, and its perpendicular to the plane of the sliding leaf 8 depth extension corresponds at least to the width of the guide slot a guide rail 9. Due to its dimensions and the inner chamber 14, the lower end member 13 is more like a box. The chamber-like cavity 14 is open at its top and there has a slot-shaped opening 15 through which the sliding wing 8 can slide. The slot-shaped opening 15 may be sealed by two lateral sealing strips 53, which may be fixed on the upper side 16 of the lower end element 13 and laterally and / or on the longitudinal edges of the upper, slot-shaped opening 45.

Since the two guide rails 9 extend into the chamber-like cavity 14 and continue therein, the sliding leaf 8 can be lowered into the chamber-like cavity 14, so that the window pane 2 has almost or completely disappeared.

The window pane 2 could be manually raised again, provided that a handle is provided on the upper horizontal bar 4 of the frame 3 of the sliding leaf 8, or by means of a crank via a crank mechanism.

On the other hand, a drive mechanism 17 may be provided to raise the window pane 2 again and thereby the window opening shut down. Such a drive mechanism 17 can be seen in Fig. 1. It is arranged in an extension of the chamber-like cavity 14. How to Fig.

1, the perpendicular extent of the chamber 14 to the plane of the sash 8 may be greater than the thickness of the window pane 2 or of that surrounding sash frame 3 for this purpose. There is one or preferably in the region of both sides of the lowered window pane

2 - each one vertically adjustable element 18, which is coupled to the frame 3 of the sliding leaf 8, for example, connected. 1 shows, by way of example, a scissor-type drive, that is to say a kind of "Nuremberg scissors" 19 with an upward deployment direction, which connects a lower anchoring part 21 fixed to the bottom of the lateral chamber extension 20 to the upper, vertically adjustable element 18. By moving apart or moving together the two lower legs 21 of the Nuremberg scissors 19 this is extended upward or collapsed down and takes over the vertically adjustable Elemennt 18 the sliding leaf 8 each with the joints 22 between the individual legs 23, 24 of the Nuremberg scissors 19 may additionally be performed in lateral guide rails 25 so that the Nuremberg scissors 19 can not bend.

Other forms of the drive mechanism 17 are conceivable. Thus, one or more vertical rotary spindles can be provided with an all-round thread, on each of which a block-shaped part with a matching internal thread is schraubverstellbar. While this block-shaped part is fixed to the frame 3 of the sliding leaf 8 and thus fixed non-rotatably, the rotary spindle itself can be rotated about its vertical axis of rotation. As a result, the block-shaped part screwed along the rotating spindle up or down, depending on the current direction of rotation of the rotary spindle. Even with such a drive mechanism 17 so that the desired closing and opening movement of the sliding leaf 8 could be brought about. Another possibility for a drive mechanism 17 'is shown in Fig. 3. It can be seen two racks 26 which are attached to lateral, vertical struts of the sliding frame 3, possibly in the region of the guide rails 9, so that they are covered by those and thus are invisible from the outside. In the region of the chamber 14 and its extension 20 gears 27 are provided, which are each in engagement with a rack 26, and influence the height shift of the racks 26 by their rotational position. As shown in Fig. 1, the two gears 27 may be coupled via shafts 28 with a common drive motor 29, optionally with a gear arranged therebetween, for a common and synchronous rotational adjustment.

Another, not shown in the drawing embodiment of the drive mechanism 17 could, for example, based on chain-shaped tension elements, which are connected in the region of a chain link with the frame 3 of the sliding leaf 8. These could be two self-contained and therefore endless chains, with an upper and lower deflection sprocket. By, for example, a pair of such, mutually aligned deflection sprockets are rotatably coupled to each other or to a common drive motor, a synchronous drive is ensured.

In all drive mechanisms 17, there is the possibility to provide two lateral drive means; In this case, care must be taken to ensure that they are in sync with each other. This is realized structurally in the embodiment of FIG. 3, by common coupling elements such as the shafts 26. In scissors drives or spindle drives and a mechanical coupling can be effected by means of such synchronization waves. In addition, there is also the possibility of an electrical coupling, for example. By both Antribe are each provided with a rotary encoder and the drive motors are synchronized control technology, so that the signals of the Encoder when lifting and lowering the sliding sash 8 are always kept in sync.

When using only one drive means eliminates such synchronization. However, a single drive means should then also be arranged centrally between the two guide rails 9, so that the sliding sash 8 can not tilt or jam. However, a central arrangement is not possible with the rack-and-pinion drive 17 'according to FIG. 3 for aesthetic reasons, because in that case a rack 26 would have to run centrally over the glass pane. Preferably, the racks 26 are concealed in the region of lateral guide slots of the window frame. Other drive or transmission elements can be arranged in the region of such guide slots, for example. Pull wires, chains or other tension elements.

In all cases, the drive mechanism 17, 17 'equipped with a drive motor, preferably with an electric motor, which is turned on depending on the desired direction of actuation in one or the other direction. This can be specified by selecting one of each two actuation switches. As a trigger switch, therefore, a double rocker switch or button can be provided, as it also finds use for lifting and lowering electric shutters. Furthermore, a lifting or lowering movement can be stopped when reaching an upper and / or lower end position by means of limit switches.

Depending on the embodiment of the drive unit, the auxiliary power for raising or lowering the window can be supplied electrically, electronically, hydraulically or magnetically. If the window is to be apparent even in the event of a power failure, for example in an emergency situation, then an unlocking device can be provided which, if it is triggered mechanically, may, together with a receiving frame under its weight and / or moved down by manual assistance, creating an escape route.

In Fig. 1 it can be seen further that in the region of the lower end member 13 also a flat insulation 30 may be provided, in particular to provide a thermal compensation to the rather unfavorable thermal insulation properties of the open hollow chamber 14, if necessary, together with extension 20. The insulation 30 lying behind a support plate for plaster 52 may be provided with a plate-shaped intermediate layer 54 as sound insulation and / or burglary protection, for example in the form of a cement-bonded plate or a metal plate.

The entire window frame 10 - consisting of the two lateral window posts 11, the upper end element 12 and the lower end element 13 - is anchored in the masonry and serves the vertical guidance of the sliding leaf. 8

For this purpose, the entire lower end element 13 is inserted into the masonry and fixed there. For this purpose, the clear wall recess should be greater in height than the height of the sliding leaf 8, namely about twice as high so that not only the upper part of the window frame 10 fits into the wall recess, but also the almost equally large lower part consisting of the lower connecting element 13 with the chamber 14 for receiving the open sliding sash 8. A suitable wall recess therefore resembles more of a door recess and extends much further down than the later window opening, ideally to the bottom of the space in question, and / or in shape a room-high opening or even beyond the ceiling height, for example, so that a high window pane whose height exceeds half the ceiling height, can be completely lowered. 1, it is possible to make the lower end member 13 in a direction perpendicular to the window plane significantly thicker than the lateral window posts 11 of the window stock 10. The thickness of the lower end member 13 may be about the thickness of the shell Wall correspond. At its large, inwardly facing flat side 31 as well as at its outwardly facing flat side 32, the lower end element 13 may additionally be provided with a surface 52 suitable as a plaster base or even as an immediate visible side. As a result, no walling of the lower end element 13 is required here at all, at most a groove in the gap region between the window frame 10 and the wall reveal. Otherwise, it can be cleaned smoothly over the lower end element 13.

The lateral, usually referred to as window frames 10 sections of a sliding window element 1 may be provided on its inner side facing the room and / or on its outside facing the building facade with a surface 52 suitable as a plaster base. For visual surfaces are, for example, on metal surfaces, but also plastics, such as (colored) acrylic glass.

Similarly, the one with the upper end element 12. Also that can be made significantly thicker in a direction perpendicular to the window plane thicker than the lateral window posts 11 of the window frame 10, for example, as thick as the lower end element 13, and it can at its inner and / or. or outer flat side 33, 34 may also be provided with a surface suitable as plaster base, so that even at this point no walling of the upper end element 12 is required, but only a grouting in the gap region between the window frame 10 and the wall reveal. Otherwise, smooth over the upper end element 12 can be cleaned away. Such a thickened upper terminating element 12 may also have one or more chambers 35, 36 in its interior to accommodate further functional elements. In such a chamber 35 there is on the one hand space for a horizontally parallel to the upper end member 12 extending shaft 37 for winding a roller shutter 38, the down in unwound state in lateral, along the window post 11 extending guides 39 down to the upper end member 13 can be performed. The guides 39 for such a roller shutter shell 38 are preferably located on the outside 40 of the sliding window 1. The shaft 37 can be manually or motor-driven for winding and unwinding the roller shutter shell 38.

On the other hand, instead of or in addition to the inside 41 of the sliding window 1, a similar mechanism for winding and unwinding a roller blind could be provided or a mechanism for raising and lowering a blind. Even those elements can be stowed in a wound-up or raised state in a chamber in the region of the upper end element 12. The winding and unwinding or lifting and lowering can be done manually or by motor. A motor, in particular an electric motor, may be part of an automatic control, so that the closing state of a roller shutter or blinds can be controlled in the absence of a person according to the time of day and / or the position of the sun.

As a further functional element, a filter mat 42a is shown in FIG. 2, which can be unwound and unwound from another shaft 43a within a chamber 36 in the upper end element 12. The shaft 43a for this filter mat 42a may be biased by a spring element, in particular in one for winding up the filter mat 42a suitable direction of rotation, so that the self-imposed filter mat 42a is pulled up and wound up.

At the lower end of the filter mat 42a may be arranged a horizontally extending crossbar 44a, which is thicker than a slot-shaped opening 45a in the upper end element 12, through which the filter mat 42a emerges from the relevant chamber 36 downwards. As a result, a complete winding of the filter mat 42a is avoided. On such a crossbar 44a in the region of the lower end of the filter mat 42a elements of a releasable connection can be provided, whose counterparts are located on the upper horizontal rail 4 of the sliding leaf 8. By means of these connecting elements, the crossbar 44a can be connected to the horizontal rail 4 in the area of the free upper edge of the sliding leaf 8 in the region of the free lower edge of the filter mat 42a.

As a result, when opening the sliding leaf 8 at the same time the filter mat 42 a unwound from its shaft 43 a and pulled down, always just so far that the clear opening above the sash 8 is completely closed by the filter mat 42 a and thus no insects can penetrate through the window 1 , When closing the sliding leaf 8, the spring element arranged on the shaft 43a always pulls the filter mat 42a upwards as far as possible and, moreover, always keeps it taut, so that it can not flutter even in a wind draft.

In this case, the filter mat 42a preferably runs in two lateral guides, which surround them tightly and thereby prevent the flow around the filter mat 42a. Preferably, the shaft 43a, the lateral guides for the filter mat 42a and the cross bar 44a are located on the outside of the sliding sash 8, so that a suspended with filter particles filter mat 42a is washed clean again by a rain.

On the other hand, it is also possible to provide a fly screen 42b which, when not in use, is wound onto a shaft 43b and can be provided at its free end with a crossbar 44b and can run in lateral guides. Preferably, the arrangement of the fly screen 42b, its shaft 43b and its lateral guides is a mirror image of the filter mat 42a and the shaft 42a and their guides, with respect to the window as a plane of symmetry.

Also, the shaft 43b for the fly screen 42b may be provided with an integrated spring, which tends to wind the fly screen with the window closed on the shaft 43b. The crossbar 44b thereby prevents the fly screen from being inadvertently drawn completely into the upper end element 12 through a slot-shaped opening 45b.

In order to provide a night ventilation with driving rain safety, when the window pane 2 is only partially open, the invention further provides a front in the upper region of the window opening aperture 46 made of glass or acrylic glass. Since the superior aperture 46 is transparent and is also only in the upper region of the window opening, the incidence of light is only slightly affected. By means of a special electric circuit, the permissible opening position of the window pane 2 can be controlled under the premise "driving rain-proofness" in such a way that it is adapted to the existing structural and country-specific characteristics, eg in stormy areas the permissible gap width would be narrower than in areas with less severe weather. The outer upper surface of the lower end member 13 is protected by a sill 47 of aluminum or another, water- and UV-resistant material. In addition, for the purpose of personal protection, for example. In the upper inner region of the upper end member 12, a contact strip 48 may be mounted by the press the window pane 2 stops immediately in any position, for example. To prevent a crushing of people.

Such a function of the immediate shutdown of the window pane 2 can also be realized by other means, for example by means of a light barrier or a laser beam whose interruption causes the window pane 2 to stop immediately, or by means of magnetic contacts or other proximity switches whose release resp Close the window 2 immediately shut down. The lower receptacle of the lifting device and the window pane 2 is preferably formed at the height of several centimeters in the lower region as a waterproof trough 50, and further, a protective film 51 or a molding on the inside of the outer insulation 30 may be arranged to reject possibly in this watertight tub 50 of water.

In order for such water, which has reached the cavity 14 or the chamber extension 15, to drain off again, a drainage line 49 can be provided from there to the outside, preferably in the lower region of the cavity 14 and / or the chamber extension 15.

Various developments of the invention are possible. Thus, the space facing a boundary surface 32 of the box 13 or a diaphragm 52 mounted there may be prepared for holding a radiator by already there appropriate mounting elements are provided, etc. Further, the insulation 30 could be formed tapered, for example. With a thickness of only a few centimeters, so that the boundary surface 32 is offset back into a niche, in which then also room for a radiator remains.
