Description

[0001] The present application relates to a pivot sash, which may in particular be in the form of a pivot door sash or a pivot window sash, according to the preamble of claim 1. Furthermore, the present application relates to a vertically oriented room boundary element, which may in particular be formed by a front door element or a window element, according to the preamble of claim 12. Furthermore, the present application relates to a method for draining water in a room boundary element according to the preamble of claim 13. Finally, the present application relates to the use of an elongated profile as a drainage profile for a pivot sash according to claim 15.

[0002] For the purposes of this application, a "pivot sash" is understood to be a sash of a room-enclosing element that is rotatable about a vertical axis of rotation relative to a fixed frame of the room-enclosing element. The fixed frame is permanently installed in a building opening of the respective building, for example, in a window opening (in which case it is a window frame) or a door opening (in which case it is a door frame). By rotating the pivot sash relative to the fixed frame, the room-enclosing element can be switched between a closed state, in which the pivot sash interacts tightly with the fixed frame, and an open state, in which the pivot sash is rotated about the axis of rotation relative to the closed position, thereby opening a room-enclosing element bounded by the fixed frame. The rotatability of the pivot sash relative to the fixed frame is typically, or rather,Depending on the type of room boundary element, this is implemented via door hinges or via tilt-and-turn or turn-only fittings. This is a well-known practice.

[0003] The present application relates in particular to such a casement window, which can be used as an outward-opening sash of a vertically oriented room boundary element. The room boundary element can be, for example, and preferably, a front door or a vertically oriented window. The outward opening of the casement window means that, for the purpose of transitioning the room boundary element from its closed to its open state, the casement window is not rotated towards the interior of the building, but rather in the opposite direction, outwards, i.e., away from the building. Such a design is common, for example, in the Netherlands for the construction of front doors. State of the art

[0004] Outward-opening rotary flaps are well known in the art. Such a rotary flap is typically designed to have at least one flap seal, by means of which it can come into contact with an outer contact surface of the fixed frame of the respective room boundary element in an at least watertight manner. In this way, the room boundary element is tightly sealed when in its closed state. The flap seal is located on the outside, meaning it is directly exposed to rain, since the rotary flap presses against the contact surface of the fixed frame from the outside when it is in its closed state.

[0005] Newly developed room enclosure elements are generally subjected to official testing before being introduced to the market, with leak tests being of particular importance. In these tests, the room enclosure element is typically subjected to high air pressure in the opening direction and simultaneously artificially sprayed with water to ensure that it seals tightly even under adverse weather conditions (storms and rain). For such leak tests, it is generally agreed that the most critical stress situation occurs with an inward-opening casement window that is subjected to high (positive) air pressure from the outside and simultaneously sprayed with water. The air pressure tends to "push" the casement window open, that is, to twist it relative to the fixed frame in such a way that the window seal loses its sealing contact with the fixed frame.If a newly developed space boundary element successfully withstands this stress situation, the test is considered successfully completed.

[0006] However, testing under different load conditions may also be relevant. This applies when the room boundary element is designed so that the casement window opens outwards. In this configuration, the casement window does not abut against an interior-facing contact surface of the fixed frame with its sash seal as described above, but rather comes into a sealing contact with an outward-facing side of the fixed frame when the room boundary element is in its closed position. The room boundary element is not subjected to external (positive) air pressure while simultaneously being rained on, as the air pressure presses the casement window firmly against the fixed frame, reinforcing the sealing effect of the outer sash seal. Consequently, water ingress under this load condition is not a concern with outward-opening room boundary elements.uncritical for an outward-opening rotating wing.

[0007] However, in a real-world stress situation, where such a room-enclosing element with an outward-opening casement window is exposed to varying air pressure, the seal may be lost. Under the influence of suction, the casement window is pulled outwards, that is, away from the inside of the room-enclosing element, which reduces the pressure of the casement window's seal against the contact surface of the fixed frame. This stress situation is therefore crucial for the seal between the casement window and the fixed frame. Practical experience, as well as testing on the rig, has shown that water falling from the outside (outside the room-enclosing element) onto an upper horizontal sash profile of the casement window's frame, and resting on the outer sash seal from above, can overcome the seal if the pressure on the sash is insufficient, thus penetrating the room-enclosing element.Such a situation cannot be taken into account analogously for inward-opening casement windows, since the (rain)water cannot accumulate on the upper side of the upper horizontal wing profile of the wing frame.

[0008] The penetrating water, viewed from the inside of the room boundary element, now rests on the upper horizontal sash profile of the casement window frame on the side of an outer sealing plane formed by the sash seal in conjunction with the fixed frame. From there, it can flow uncontrollably and, in particular, over the sash profiles of the casement window frame into the building's interior, i.e., to the inside of the room boundary element, causing damage. In a real-world installation, this would allow water to enter the building under suitable weather conditions. Task

[0009] The present application therefore aims to provide a hinged door that prevents water from penetrating the building even under the described load conditions. Furthermore, the present application aims to provide a vertically oriented room boundary element that prevents water from penetrating the interior of the building under the described load conditions. Solution

[0010] The underlying problem is solved according to the invention by means of a rotary vane having the features of claim 1. Advantageous embodiments will become apparent from the associated dependent claims, the description and the exemplary embodiment.

[0011] The casement window comprises a rectangular frame formed by four rigidly connected wing profiles extending in a common plane. Each wing profile is elongated, meaning that its length, measured parallel to its axis, significantly exceeds its other dimensions (width, height) measured perpendicular to that axis. The wing profiles are hollow chamber profiles, exhibiting multiple hollow chambers extending along their entire length and oriented parallel to their respective axes. The wing profiles are preferably formed from extruded plastic profiles. Alternatively, they could be formed from extruded aluminum profiles.

[0012] To connect the sash profiles to the respective sash frame, they are firmly joined at their ends, for example, and preferably, by welding. The sash profiles can, for instance, be mitered at their ends at a 45° angle to their longitudinal axis, so that the profile axes of two sash profiles joined at their ends are oriented at a 90° angle to each other. In this way, the rectangular sash frame is formed by joining a total of four sash profiles.When the casement window is in its intended vertical orientation, with the wing plane oriented vertically, the wing frame accordingly comprises an upper horizontal wing profile, vertical wing profiles oriented parallel to each other and adjoining both ends of the upper horizontal wing profile, and a lower horizontal wing profile that is oriented parallel to the upper horizontal wing profile and connected to the vertical wing profiles at its opposite ends, corresponding to the upper horizontal wing profile. The wing profiles forming the wing frame preferably have identical cross-sectional areas.

[0013] In practice, it is common for a specific wing profile with a particular cross-sectional area to be manufactured in a long length, for example, 6 meters, by the respective manufacturer. Such a "long" wing profile is then cut to form individual wing frames, preferably by miter cuts. The long wing profile is cut to the lengths required by the respective wing frame. Finally, the individual wing profiles can be joined together as described, in particular by welding, to form the desired wing frame.

[0014] The casement window also includes a flat infill oriented parallel to the sash plane, which is enclosed by the sash frame. This infill can, for example, be made of glass, possibly in the form of multiple glazing. It is also conceivable that the infill could be made of plastic, composite, or another type of material. All types of infills are known in the art and can be used for casement window sashes as well as for casement door sashes.

[0015] The casement window further comprises at least one sash seal attached to the sash frame. Preferably, the sash seal is formed around the entire perimeter of the sash frame and is enclosed in a frame-like manner, preferably being attached to all four sash profiles of the sash frame. In this configuration, the sash seal has a total of four sections, each section being assigned to one of the sash profiles (horizontal at the top, vertical on the left, vertical on the right, and horizontal at the bottom) of the sash frame. In this configuration, the respective sections of the sash seal extend parallel to the profile axes of their respective sash profiles, with the individual sections of the sash seal being connected to each other at 90° angles, analogous to the sash frame. This results in the overall rectangular, frame-like shape of the sash seal.

[0016] A non-contiguous design of the door seal is also conceivable, where, for example, not each door profile has its own section of the seal. This can be the case, for instance, with a room-enclosing element designed as a front door unit with a so-called "zero threshold." The fixed frame of such a room-enclosing element is not continuous, as the lower horizontal section is missing. This lower section would be formed in a "normal" front door unit (without a zero threshold) by a standard threshold projecting vertically upwards from the floor, for example, with a height of 20 mm. Such a threshold is not present in a door unit with a zero threshold.With a zero threshold, a section of the sash seal associated with the lower horizontal sash profile of the sash frame would be conceivable, but it would not fulfill a sealing function as such, since it would not laterally abut a floor threshold. Therefore, it is conceivable, for example, that the sash seal in this configuration of the room boundary element has only three sections, with the first being associated with the upper horizontal sash profile and the other two with the two vertical sash profiles. It is also conceivable to design the sash seal with a section associated with the lower horizontal sash profile in a zero threshold configuration, which would be non-functional. Other situations in which the sash seal is not continuous are also conceivable. Nevertheless, the self-contained, continuous design of the sash seal is preferred.

[0017] The sash seal is designed and configured to, when the casement sash is in a closed position, interacting with a fixed frame of the room boundary element in such a way as to close a room opening defined by the fixed frame, move in a direction perpendicular to the sash plane towards the sealing surface on the fixed frame. In other words, direct contact between the casement sash and the fixed frame when the casement sash is in its closed position consists, at least in part, of the sash seal of the casement sash resting against or being pressed against the fixed frame. It is preferable if the sash seal is pressed against the sash frame in a direction perpendicular to the sash plane (i.e., when the casement sash is in its intended horizontal orientation).A suitable contact surface is provided on the fixed frame for this purpose, which is preferably oriented parallel to the wing plane.

[0018] At least one upper section of the at least one sash seal is attached to the upper horizontal sash profile of the sash frame. This upper section of the sash seal extends parallel to the profile axis of the upper horizontal sash profile. For example, and preferably, the upper section of the sash seal is attached to a projection of the sash profile that, viewed parallel to the sash plane, extends away from the infill. By arranging the upper section of the sash seal on this projection, this section can engage with or abut the fixed frame particularly easily.

[0019] The sash seal is preferably made of rubber or a rubber-like material. For connection with the sash profiles of the sash frame, the sash seal preferably has a positive locking area by means of which it can interact with corresponding positive locking areas of the sash profiles.

[0020] The rotary wing according to the invention is characterized by an elongated, channel-shaped drainage profile, which is arranged in a force-transmitting manner on the upper horizontal wing profile. The drainage profile is oriented parallel to the profile axis of the upper horizontal wing profile and extends at least substantially over its entire length. For example, and preferably, the drainage profile can extend over at least 90%, preferably at least 95%, and more preferably at least 97% of the length of the upper horizontal wing profile. The length of the upper horizontal wing profile here refers to its maximum length.In one embodiment, where, for example, the upper horizontal wing profile is mitered at its opposite ends, the length of the upper horizontal wing profile is measured between the outermost corners of the wing profile, opposite each other in the longitudinal direction of the wing profile, relative to the wing plane. The drainage profile is preferably physically separate from the upper horizontal wing profile and thus constitutes an independent profile component. In other words, the upper horizontal wing profile and the drainage profile are preferably not formed in one piece. Preferably, the drainage profile is bonded or welded to the upper horizontal wing profile. Preferably, the drainage profile is formed from an extruded plastic profile, for example, made of PVC, or from an extruded aluminum profile.

[0021] The drainage profile is arranged on the upper horizontal sash profile in such a way that – when viewing the casement sash in its intended vertical orientation – it is located below the upper section of the sash seal. In other words, the drainage profile extends parallel to the upper section of the sash seal, which also extends parallel to the profile axis of the upper horizontal sash profile. The drainage profile is therefore also horizontally oriented.In the context of the present application, the arrangement "below" means an arrangement of the drainage profile relative to the upper section of the wing seal such that water which manages to overcome the seal against the fixed frame caused by the wing seal when the rotating wing is in its closed position, falls or can fall from the upper section of the wing seal onto the drainage profile due to the effect of gravity.

[0022] Preferably, the drainage profile is arranged at least substantially aligned with the upper section of the wing seal in the vertical direction. "Substantially aligned" means that, viewed in a cross-section perpendicular to the profile axis, the distance measured perpendicular to the wing plane between a first plane containing the centroid of the upper section of the wing seal and oriented parallel to the wing plane, and a second plane containing the centroid of the drainage profile and oriented parallel to the wing plane, is at most 20 mm, preferably at most 10 mm.

[0023] Preferably, there is a vertically measured gap between the upper section of the wing seal and the drainage profile, which is, for example, and preferably, in a range between 0.5 mm and 10 mm, preferably between 1 mm and 5 mm. "Gap" here refers to a clear distance, that is, a distance between a lower end of the upper section of the wing seal facing the drainage profile and an upper end of the drainage profile facing the upper section of the wing seal. The drainage profile serves to collect or capture water that unintentionally bypasses the wing seal in its upper section.

[0024] The drainage profile is preferably arranged on the upper horizontal sash profile such that a space extending vertically between the upper section of the sash seal and the drainage profile is free of obstructions, except for strike plates if it is a mullion element. This allows water falling from the upper section of the sash seal to reach the drainage profile unhindered, in particular without contact with other sections of the upper horizontal sash profile or other objects, and be collected by it. For this purpose, the drainage profile is preferably arranged – viewed in a direction parallel to the sash plane – on an outer surface of the upper horizontal sash profile facing away from the infill of the casement sash.

[0025] The drainage profile is sealed at its longitudinally overlapping ends with end caps. These prevent water from escaping from the ends of the drainage profile. The end caps, preferred embodiments of which are described separately below, can, for example, and preferably, be formed from one-piece plastic parts, preferably injection-molded.

[0026] A fluid flow connection exists between the drainage profile and at least one hollow chamber of the upper horizontal airfoil, allowing water absorbed by the drainage profile to flow from the drainage profile into at least one hollow chamber of the upper horizontal airfoil and be drained away from or out of the drainage profile via this hollow chamber. The fluid flow connection between the drainage profile and the at least one hollow chamber can, for example, and preferably, be in the form of at least one opening. Preferably, several such openings are present, distributed along the drainage profile over a length of the upper horizontal airfoil measured parallel to the profile axis.

[0027] The casement window according to the invention has many advantages. It is based on the understanding that, by design, the frame of an outward-opening casement window projects outwards relative to the fixed frame in a direction perpendicular to the sash plane. This means that the upper horizontal sash profile offers a surface on its outer side for (rain)water to collect and thus come into contact with the upper section of the sash seal from the outside. In unfavorable conditions, the water can overcome the outer sealing plane of the room boundary element, i.e., the area between the upper section of the sash seal and the respective contact surface of the fixed frame, and penetrate the room boundary element. The drainage profile then has the effect of "collecting" this water and thus preventing it from running off uncontrollably.This prevents the undesired ingress of water into the interior of the building, a problem that can occur with prior art. Instead, the water entering the room boundary element is channeled away within the element via the sash frame, specifically through at least one hollow chamber of the upper horizontal sash profile that is fluidically connected to the drainage profile. Preferably, the water is also channeled away via the other sash profiles. This drainage leads to the outside of the room boundary element ("outwards").

[0028] A further advantage of the rotating wing according to the invention is that the drainage profile can be retrofitted particularly easily. This simply requires attaching the drainage profile to the upper horizontal wing profile of a respective wing frame, for example by bonding it to the upper horizontal wing profile. The design of the flow-related connection between the drainage profile and the at least one hollow chamber of the upper horizontal wing profile can be achieved, for example, and preferably, by means of at least one bore, which can be drilled manually using a drill. Preferably, several such bores are made along the longitudinal axis of the drainage profile to facilitate the flow of water from the drainage profile into the hollow chamber of the upper horizontal wing profile.In this way, it is particularly easy to upgrade already installed room boundary elements with outward-opening pivot doors.

[0029] In a preferred embodiment, the at least one hollow chamber, into which water can be drained from the drainage profile, extends in a drainage plane oriented parallel to the sash plane. This drainage plane—viewed from the inside of the sash—is located beyond the outer sealing plane, which is defined by the contact of the sash seal with an associated contact surface of the fixed frame. In other words, the hollow chamber preferably extends "further outwards" relative to the sealing plane. This has the advantage that the water can be drained particularly easily—viewed from the inside of the sash—from the sash frame into the surrounding environment beyond this sealing plane.Preferably, the drainage profile is arranged at least approximately in the sealing plane ("below" the upper section of the wing seal), wherein the flow connection is directed "outwards", i.e., the water absorbed by the drainage profile leads to the side of the sealing plane facing away from the filling.

[0030] In a preferred embodiment of the rotary wing, the hollow chamber of the upper horizontal wing profile, which can be used for water drainage, is fluidically connected to a hollow chamber of at least one of the two vertical wing profiles, which are rigidly connected to the upper horizontal wing profile. In this way, the water can flow from the hollow chamber of the upper horizontal wing profile into the respective hollow chamber of the respective vertical wing profile and be drained downwards in a vertical direction via the latter hollow chamber. Preferably, the wing frame is symmetrical in that the hollow chamber of the upper horizontal wing profile is fluidically connected to corresponding hollow chambers of both vertical wing profiles. This also ensures that the water has to travel the shortest possible path along the upper horizontal wing profile before it can enter one of the two vertical wing profiles.

[0031] In a further preferred embodiment, the hollow chamber of the respective vertical airfoil, which can be used for water drainage, is fluidically connected to a hollow chamber of the lower horizontal airfoil. In this way, the water can flow from the hollow chamber of the vertical airfoil (or both vertical airfoils) into the hollow chamber of the lower horizontal airfoil and be further drained via this hollow chamber.

[0032] In a further preferred embodiment, the latter hollow chamber of the lower horizontal sash profile has at least one downward-facing drainage opening through which water contained in this hollow chamber can escape from the lower horizontal sash profile. Preferably, several such drainage openings are present through which the water can escape. In this way, the water, originally collected by the drainage profile and falling from the upper section of the sash seal, can be channeled, in a particularly preferred manner, via the sash profiles of the sash frame, namely within the sash profiles via their hollow chambers, and finally discharged to the outside of the space-enclosing element. This prevents water from entering the interior of the respective building. The hollow chambers of the sash profiles are thus used as flow channels for the unintentionally entered water.The at least one drainage opening is preferably arranged on the lower horizontal wing profile in such a way that the water can escape from the lower horizontal wing profile beyond the outer sealing plane of the space boundary element.

[0033] In an advantageous embodiment of the casement window, the drainage profile is bonded to the upper horizontal sash profile to create the force-transmitting connection. This bonding is achieved with a contact surface of the upper horizontal sash profile, which is preferably flat. Preferably, the drainage profile interacts with an adhesive strip that extends along the entire length of the drainage profile. Using such an adhesive strip makes mounting the drainage profile to the upper horizontal sash profile of the sash frame particularly easy.Especially when retrofitting the drainage profile to an already installed casement window, the installer only needs to peel off the respective protective strip from the adhesive strip so that the adhesive surface of the adhesive strip is exposed, and then place the drainage profile with the adhesive strip against the contact surface of the upper horizontal sash profile and press it on.

[0034] In a preferred embodiment of the rotary wing, the drainage profile, viewed in a cross-section perpendicular to its longitudinal axis, has a first leg extending in a first plane and a second leg extending in a second plane, the two legs merging at their mutually facing ends. This merging is preferably formed with a curve. Preferably, the drainage profile has only these two legs, that is, it comprises exactly two legs in total.

[0035] If the drainage profile is designed in this way, it can be further advantageous if the first plane in which the first leg extends and the second plane in which the second leg extends together enclose an angle between 40° and 80°, preferably between 50° and 70°. Preferably, this angle is approximately or exactly 60°. In this configuration of the drainage profile, the first plane of the first leg—when considering the rotating wing in its intended vertical orientation—can preferably be oriented vertically. In this configuration, the second leg is connected to the first leg at a lower end in the vertical direction and extends upwards at an angle to the first leg.This gives the drainage profile the shape of a channel, whereby water falling onto the drainage profile from above, from the upper section of the wing seal, falls onto the second leg and, due to the inclined orientation of the second leg, flows towards its lower end, where it transitions into the vertically oriented first leg. The water thus collects at the transition between the two legs.

[0036] For the arrangement of the fluid-flow connection between the drainage profile and the at least one hollow chamber of the upper horizontal wing profile, the area where the two legs of the drainage profile meet or merge into one another is particularly well suited in this design of the drainage profile, since the water falling from the upper section of the wing seal automatically collects there due to gravity. If, for example, the fluid-flow connection is formed by one or more openings to the at least one hollow chamber of the upper horizontal wing profile as described above, these openings are preferably located in the area where the two legs of the drainage profile merge. Such a design can also be seen in the exemplary embodiment shown below.

[0037] If the drainage profile is connected to the upper horizontal wing profile by means of an adhesive strip, forming an adhesive bond, the described design of the drainage profile with two legs is particularly advantageous if the adhesive strip is arranged on the outer side of the first leg facing away from the second leg. In this way, the drainage profile can be bonded particularly easily to a corresponding contact surface of the upper horizontal wing profile using the adhesive strip, with both the first leg of the drainage profile and the contact surface of the wing profile preferably being vertically oriented.

[0038] In a preferred embodiment of the rotary wing, at least one of the two end caps, preferably both end caps, has an inclined drainage area, wherein the drainage area is inclined towards the drainage profile in the manner of a ramp. This allows water that overcomes the upper section of the wing seal in a lateral end region (close to a vertical wing profile) to fall onto the drainage area and be channeled along it to the drainage profile. This design is based on the consideration that the drainage profile should be closed at its end, for which the end caps are necessary, since water can also overcome the upper section of the wing seal in the area of ​​the end caps.To prevent this water from flowing uncontrollably inside the room boundary element, but rather to allow it to be drained away in a controlled manner via the drainage profile, the end caps are preferably also designed with a water-draining shape, so that the falling water can be directed in a controlled manner towards the drainage profile.

[0039] Preferably, both end caps are designed as mirror images of each other (one end cap for the "left" end of the drainage profile and the other end cap mirrored and identical for the "right" end of the drainage profile).

[0040] Preferably, the end caps are each connected to the drainage profile by means of a connecting element. The connecting element is preferably a screw by which the respective end cap is screwed to the drainage profile. For this purpose, the drainage profile may preferably have a corresponding mating profile that is designed and configured to interact with the connecting element.

[0041] The underlying problem is further solved by means of a vertically oriented space boundary element with the features of claim 12. Advantageous embodiments will become apparent from the description and the exemplary embodiment.

[0042] The room-defining element, which can be formed in particular by a front door element or a window element, comprises at least one casement leaf that opens outwards around a vertical axis of rotation. A design with multiple casement leaves is also conceivable, for example in the case of a multi-leaf door that has a fixed leaf (one that undercuts the other) and a moving leaf (one that overlaps the other).

[0043] Furthermore, the room boundary element comprises a vertically oriented, fixed frame on which the casement sash is rotatably mounted, forming the vertical axis of rotation. In an installation situation where the room boundary element is integrated into a building, the fixed frame is permanently inserted into a building opening. When in the closed position, the casement sash rests against the fixed frame in such a way that it closes off a room opening defined by the fixed frame. The room boundary element is then in its closed state.

[0044] The space boundary element according to the invention is characterized in that the rotating wing is designed according to the present invention or one of its advantageous embodiments.

[0045] The advantages arising from the room boundary element according to the invention have already been described above in connection with the pivot door according to the invention. They apply analogously to the room boundary element. In particular, water unintentionally penetrating the room boundary element can be collected and drained away in a controlled manner by means of the drainage profile of the pivot door. This prevents uncontrolled water from penetrating the room boundary element and ultimately the building in which the room boundary element is installed.

[0046] Furthermore, the present invention is solved by means of a method having the features of claim 13. Advantageous embodiments will become apparent from the associated dependent claim, the description, and the exemplary embodiment.

[0047] The method serves to drain water from a space boundary element designed according to the present invention or one of its advantageous embodiments. The method provides that water which manages to overcome the seal between the upper section of the sash seal and the fixed frame, despite the sash being in its closed position, is collected by means of the drainage profile arranged vertically below the upper section of the sash seal and, starting from the drainage profile, is directed into at least one hollow chamber of the upper horizontal sash profile of the sash frame of the sash and discharged within the hollow chamber. The advantages resulting from this have already been described above in connection with the sash according to the invention and are analogous for the method.

[0048] In a preferred embodiment of the method, the water is guided through, preferably identical, hollow chambers of various wing profiles rigidly connected to one another to form the wing frame of the casement window, until the water finally exits into the surrounding area of ​​the room boundary element through at least one drainage opening formed on a lower horizontal wing profile of the casement window. This embodiment has the particular advantage that the water, which unintentionally overcomes the wing seal, is completely drained away within the wing frame, apart from its initial collection by means of the drainage profile.Guiding the water within the hollow chambers of the individual sash profiles of the sash frame prevents unintentional water leakage at other points within the room-enclosing element, as the hollow chambers are self-contained and tightly interconnected by the connection of the sash profiles to the sash frame. In other words, the water is "trapped" within the sash frame until it exits through at least one drainage opening. This ensures the controlled discharge of water to the (external) surroundings of the room-enclosing element.

[0049] Finally, it is further an object of the present invention to use an elongated profile, preferably formed from an extruded plastic profile, for example from PVC, or from an extruded aluminum profile, as a drainage profile for a pivoting wing of a vertically oriented room boundary element that opens outwards about a vertical axis of rotation. The pivoting wing is designed according to the present invention or one of its advantageous embodiments. The drainage profile is elongated and channel-shaped and is designed and configured to be arranged on the upper horizontal wing profile of the wing frame of the pivoting wing and to extend parallel to its profile axis at least substantially over the entire length of the upper horizontal wing profile.Furthermore, the drainage profile is designed and configured to be positioned on the upper horizontal sash profile in such a way that, when the casement sash is viewed in its intended vertical orientation, the drainage profile is located below the upper section of the sash seal. This has the effect that any water that manages to overcome the seal against the fixed frame created by the upper section of the sash seal when the casement sash is in its closed position can fall from the sash seal onto the drainage profile under the influence of gravity. The drainage profile is also designed and configured to interact with an end cap at each of its longitudinally opposite ends, by means of which the drainage profile is sealed at its ends to prevent water from escaping.Between the drainage profile and at least one hollow chamber of the upper horizontal wing profile there is a flow-technical connection, so that water absorbed by the drainage profile can flow from the drainage profile into this hollow chamber and be drained away from the drainage profile via this hollow chamber.

[0050] The use of the profile as a drainage profile results in the advantages already described above in connection with the rotary wing according to the invention. In particular, water that overcomes the upper section of the wing seal can be collected and drained away particularly easily by means of the drainage profile.

[0051] The profile used as a drainage profile is preferably designed according to one or more of the embodiments described above as advantageous. In particular, it can be advantageous if the drainage profile, as described above, has two legs extending in a plane, the planes together forming an angle. Furthermore, it is advantageous if the profile used as a drainage profile has a counter-profile designed to interact with a fastener. If the fastener is advantageously formed by a screw, the counter-profile is preferably formed by a screw channel. In this way, the profile is particularly well suited for connection with end caps.

[0053] One embodiment, which is described in the Figures 1 to 12 As shown, it includes a vertically oriented space boundary element. 3,This is a single-leaf front door element with an outward-opening pivot leaf. 1 is formed. The space boundary element 3 This includes a fixed framework 12, which is permanently installed in a building opening of a building not shown. On the fixed frame 12 is the rotating wing 1 around a vertical axis of rotation 2 The rotating wing is mounted on a pivot. 1 can around the axis of rotation 2 relative to the fixed frame 12 can be rotated. In this way, the room boundary element can be 3 between one in the left part of Figure 1 depicted closed state and a in Figure 1 to be converted to the open state shown on the right.

[0054] When the space boundary element is present 3 In the closed state, the rotating wing 1 and the fixed frame 12in such a way that one through the fixed frame 12 limited space opening 13 is locked. The rotating door 1 It is in its closed position. It lies in a direction perpendicular to a wing plane. 5 a wing frame 4 of the rotating wing 1, That means in the horizontal direction, on the fixed frame. 12 sealing. "Sealing" here means, and preferably at least resistant to driving rain. Preferably, the casement sash 1 and fixed frame close together. 12 Furthermore, they are airtight when the pivot wing 1 is in its closed position. When in the open state, the pivot wing 1 is, compared to the closed state of the space-bounding element 3, at least a certain distance around the axis of rotation 2 relative to the fixed frame. 12 twisted, so that at least a gap exists between the fixed frame 12and results in the pivot wing 1. The pivot wing 1 is in an open position. Here, and preferably, the pivot wing 1 can rotate over a wide range of approximately 180° relative to the fixed frame. 12 can be rotated. The extent of this rotation depends on the specific installation situation of the room boundary element. 3 away.

[0055] The fixed frame 12 In the example shown, there are a total of four elements, namely three frame profiles. 43, 44, 45 and a threshold 32, formed. The threshold 32 forms a lower horizontal section of the fixed frame 12, while the two frame profiles 44, 45 each are vertically oriented and located at opposite ends of the threshold 32 are connected to the same. The third frame profile 43 is parallel to the threshold 32horizontally oriented and is also connected to the two vertical frame profiles 44, 45 connected in this way the three frame profiles 43, 44, 45 and the threshold 32 in the manner of a frame to the fixed frame 12 joined together, with the frame profiles 43, 44, 45 and the threshold 32 extend in a common, vertically oriented frame plane. In the case of a casement window. 1 In its closed position, the frame plane of the fixed frame 12 and the wing plane 5 of the wing frame 4 oriented parallel to each other.

[0056] The wing frame 4 of the rotating wing 1 is made up of four rigidly connected wing profiles 6, 7, 8, 9 formed. When present in a properly oriented vertical position of the rotating wing. 1, the in the Figure 1 and 2is shown and in which the wing plane 5 The first wing profile of the wing frame is vertically oriented. 4 from an upper horizontal wing profile 6 formed. At the opposite ends of the upper horizontal wing profile. 6 Each of the two vertically oriented wing profiles closes. 7, 8 at. At the lower end of the wing frame 4 This one has a lower horizontal wing profile. 9 up, parallel to the upper horizontal wing profile 6 is oriented and also at its ends with the vertically oriented wing profiles 7, 8 is connected. In this way, the four wing profiles form 6, 7, 8, 9 together the surrounding, self-contained wing frame 4. The wing profiles 6, 7, 8,9 extend in a common plane, which forms the wing plane 5. This is the case when the rotating wing is oriented as intended. 1, as they in the Figure 1 and 2 It is shown in a vertical orientation.

[0057] In the example shown, the wing profiles are 6, 7, 8, 9 each along a respective profile axis 25 long, extruded plastic profiles are formed, each with identical profile cross-sections. The wing profiles 6, 7, 8, 9 are welded together and thus firmly connected.

[0058] The rotating wing 1 furthermore includes a planar plane parallel to the wing plane 5 oriented filling 10, the edge surrounding the wing frame 4 is enclosed. In the example shown, the filling is 10Opaque and formed from a composite filling. For the retention of the filling. 10 in a direction perpendicular to the wing plane 5 The wing profiles 6, 7, 8, 9 each with a clamping profile 37 together. This is particularly evident from the Figure 7 and 8 .

[0059] The rotating wing 1 also includes a wing seal 11, the wing frame 4 is attached. The wing seal 11 In the example shown, one of the number of wing profiles is included. 6, 7, 8, 9 corresponding number of sections that together form the wing seal 11 form. Each of the wing profiles 6, 7, 8, 9 is a section of the wing seal 11 assigned, whereby the respective section of the wing seal 11 parallel to a respective profile axis 25 of the associated wing profile 6, 7, 8, 9over the entire length of the respective wing profile 6, 7, 8, 9 extends. The individual sections of the wing seal 11 are elongated and connected to each other in such a way that the wing seal 11 It has the form of a surrounding, self-contained frame. An outer sealing layer. 39 of the space boundary element 3 is parallel to the wing plane 5 of the wing frame 4 oriented. The outer sealing plane 39 is through the installation of the wing seal 11 at a corresponding contact surface 55 of the fixed frame 12 defined. This contact surface 55 is here and preferably on each of the frame profiles 43, 44, 45 and at the threshold 32 trained.

[0060] If the room boundary element 3 were designed with a so-called "zero threshold", the floor threshold would not project upwards above the level of the floor and consequently would not provide a lateral stop for a lower section of the sash seal on the lower horizontal wing profile 9. 11 available. With such a design, the contact surface would be 55 of the fixed frame 12 consequently only on the frame profiles 43, 44, 45 formed. The sealing against the floor threshold would be achieved in a different way, for example by means of a drop seal.

[0061] The wing seal 11 The wing seal is formed here, preferably, from a rubber-like, elastic material. 11 is formed by creating a positive locking connection with the sash frame 4 connected. The wing seal provides for this purpose. 11here and preferably in each of its individual sections a positive locking area 56 in the manner of a barb that engages in a feature on the respective wing profile 6, 7, 8, 9 well-developed undercut 57 is positively locked in place. In the example shown, the wing profiles exhibit this. 6, 7, 8, 9 each one overhang 26 on, at which the respective section of the wing seal is attached 11 is attached. The respective overhang 26 extends in a direction parallel to the wing plane 5 into a space separated from the filling 10 away from the direction towards the outside, so that the wing frame 4 with the overhangs 26 the individual wing profiles 6, 7, 8, 9 or the sections of the wing seal attached to it 11 in tight contact with the respective contact surface 55 of the fixed frame 12This can occur when the rotating wing 1 moves into its closed position. For this purpose, the sections of the wing seal are... 11 on a fixed frame 12 facing side of the respective overhang 26 arranged. During the movement of the rotary vane 1 around the axis of rotation 2 into its closed position, the vane seal is 11 therefore in a direction perpendicular to the wing plane 5, that is, in a horizontal direction, against the fixed frame 12 guided so that the wing seal 11 in a direction perpendicular to the wing plane 5 on the fixed frame 12, namely at its contact surface 55, to the sealing system.

[0062] After all this, an upper section is formed on the upper horizontal wing profile 6 of the wing frame 4. 41 the wing seal 11 attached. This upper section 41extends – just like the other sections of the wing seal. 11 related to their respective associated wing profile 7, 8, 9 - parallel to the profile axis 25 of the upper horizontal wing profile 6.

[0063] As can be seen particularly well from the Figures 3 to 7 The result is that the rotating wing includes 1 furthermore, a drainage profile 14. This is elongated and channel-shaped. The drainage profile 14 is transmitted in a force-transmitting manner to the upper horizontal wing profile 6 arranged, wherein a longitudinal axis of the drainage profile 14 parallel to the profile axis 25 of the upper horizontal wing profile 6 extends. Furthermore, the drainage profile shows 14 such a length measured parallel to its longitudinal axis that it essentially extends over an entire length parallel to the profile axis 25measured length of the upper horizontal wing profile 6 The drainage profile extends here, and preferably here. 14 completely between opposing end edges 53 of the upper horizontal wing profile 6, on which this wing profile 6 here, and preferably each piece is cut at a miter. The end edge 53 Therefore, it runs here at an angle of 45° relative to a perpendicular to the profile axis. 25 oriented transverse plane of the upper horizontal wing profile 6. The entire length of the upper horizontal wing profile 6, the area between the outer, opposite corners 52 The length of the wing profile 6, as measured, is therefore only minimally larger in magnitude than the length of the drainage profile. 14, since the drainage profile 14 along the sloping end edge 53 looking slightly "below" the corners52 is arranged.

[0064] The drainage profile 14 is formed here, and preferably, from an extruded aluminum profile. For the design of the force-transmitting connection with the upper horizontal wing profile. 6 is the drainage profile 14 with the upper horizontal wing profile 6 bonded. This is done here, and preferably by means of an adhesive strip described in more detail below. 17.

[0065] The drainage profile 14 is thus attached to the upper horizontal wing profile 6 arranged so that, viewed vertically, it is below the upper section 41 the wing seal 11 extends. In other words, the upper section extends 41 the wing seal 11 and the drainage profile 14parallel to each other. Here, and preferably, there is a vertically measured distance between the upper section 41 of the wing seal 11 and the drainage profile 14. 54 before. This distance 54, the ends of the upper section facing each other 41 the wing seal 11 on the one hand, and the drainage profile 14 on the other hand is measured (see Figure 9 ), In the example shown, the drainage profile is approximately 1.5 mm. 14 Viewed from a vertical direction, it is essentially aligned below the upper section. 41 the wing seal 11. In the example shown, an offset measured perpendicular to the wing plane 5 is shown. 58 between one the focus 59 of the upper section 41 the wing seal 11 including the first plane oriented parallel to the wing plane 5 61 and one of the focus60 of the drainage profile 14 including the second plane oriented parallel to the wing plane 5 62 at most of such an amount that water which comes from the upper section 41 due to gravity, it falls vertically and is "captured" by drainage profile 14. The aforementioned offset 58 The difference here is approximately 5 mm.

[0066] When positioning the drainage profile 14 in a direction perpendicular to the wing plane 5 relative to the upper section 41 the wing seal 11 Functionally, it depends on the water that reaches the upper section. 41 the wing seal 11 in the presence of the rotating wing 1 in its closed position unintentionally overcomes and from the upper section 41 the wing seal 11 falling down due to gravity, onto the drainage profile 14It falls down and is consequently collected and thus absorbed by this system. In other words, this water falls due to the design of the drainage profile. 14 relative to the upper section 41 the wing seal 11 by the effect of gravity from the upper section 41 from above onto the drainage profile 14, that can absorb this water accordingly. This is particularly evident from the cross-sectional view according to Figure 7 and the stylized water droplet shown there 46 as well as based on Figure 9 recognizable.

[0067] The drainage profile 14 is fitted with an end cap at each of its ends opposite each other in its longitudinal direction. 15 closed. This is particularly evident from the Figures 2 to 6 as well as 11 and 12. The end caps 15 They serve to ensure that water which falls on the drainage profile 14has fallen down and been taken over by it, not unintentionally emerging from the drainage profile at the end 14 can leak out. The end caps 15 are here and preferably each formed from one-piece plastic parts, each connected by means of a connecting element 27 with the drainage profile 14 to be connected. The connecting means 27 are each formed by screws that are attached to the drainage profile 14 trained counterpart profile 35 intervene, which here is formed by a screw channel. The end caps 15 are designed here, preferably in a mirror-image configuration, to be identical in construction.

[0068] The end caps are particularly preferred. 15 in the example shown, each with a derivative range 24 formed, which is inclined towards the drainage profile 14 in the manner of a ramp. This is particularly evident from the Figure 11 and 12 . In this way the end caps 15 suitable for water that covers the upper section 41 the wing seal 11 overcomes the edge, to take over and across the drainage area 24 to the drainage profile 14 to derive.

[0069] To drain the absorbed water, there is a flow-technical connection between the drainage profile. 14 and a hollow chamber 16 of the upper horizontal wing profile 6. In the example shown, this fluid-technical connection consists of a plurality of openings. 28, 29, which are in corresponding positions on the drainage profile 14 and the upper horizontal wing profile 6 are trained. This is particularly evident from the Figures 3 to 6 . The breakthroughs 28, 29are formed here, and preferably by boreholes, which are manually drilled into the drainage profile using a drilling machine 14 and the upper horizontal wing profile 6 were installed. For this purpose, the drainage profile is required for installation. 14 on the wing profile 6 Initially planned, the drainage profile 14 to position and transfer force to the wing profile 6 to connect them. Then, using a drill, the individual openings are successively made. 28, 29 introduced, thereby creating both a first leg 21 of the drainage profile 14 as well as a wall of the wing profile 6 be breached. Through these breaches 28, 29 This can be determined from the drainage profile. 14 absorbed water into the hollow chamber 16 of the upper horizontal wing profile 6 drain away or overflow. In this way, the drainage profile is defined.14 drained. This is in Figure 7 using stylized water droplets 46, 47, 48 illustrated.

[0070] Here, and preferably, are the wing profiles. 6, 7, 8, 9 of the wing frame 4 connected in such a way that the hollow chambers of the wing profiles 6, 7, 8, 9 They are fluidically connected to each other. This also applies to the hollow chamber. 16, into the drainage profile 14 The absorbed water is drained away. Accordingly, the sash frame is designed... 4 designed in such a way that it fits into the hollow chamber 16 of the upper horizontal wing profile 6 The introduced water passes through corresponding hollow chambers of the two vertical wing profiles. 7, 8 and finally a corresponding hollow chamber 42 of the lower horizontal wing profile 9 can drain away. Starting from the hollow chamber 16 of the upper horizontal wing profile 6The water will therefore first flow in a horizontal direction (parallel to the profile axis). 25 of the upper horizontal wing profile 6) along the hollow chamber 16 to the ends of the wing profile 6 directed and connected to the hollow chambers of the two vertical wing profiles 7, 8 transferred. The water is then channeled vertically through this, as in Figure 7 by means of the arrow shown there 49 This illustrates the point.

[0071] From the vertical wing profiles 7, 8 The water eventually enters the hollow chamber. 42 of the lower horizontal wing profile 9 about. The latter hollow chamber 42 is with a the overhang 26 of the lower horizontal wing profile 9 associated further hollow chamber 31 of the lower horizontal wing profile 9connected in a fluid-technical manner, so that the water flows into this hollow chamber 31 can be breached. The latter hollow chamber 31 is finally here and preferably with a plurality of drainage openings 33 provided with openings through which water can escape from a lower end of the wing frame 4. This is particularly evident from the following: Figure 8 and the stylized water droplets depicted there 50, 51. One of the drainage openings 33 is in Figure 8 by means of a hatched area of ​​the lower horizontal wing profile 9 shown, with the hatched area forming the drainage opening. 33 from the lower horizontal wing profile 9 removed, for example by means of a borehole.

[0072] The drainage profile is particularly advantageous. 14 in the example shown, relative to the outer sealing plane39 arranged and fluidically connected to the hollow chamber 16 of the upper horizontal wing profile 6 connected that the water is either already - from the inside of the rotating wing 1 viewed - beyond the outer sealing plane 39 from the drainage profile 14 is taken over or the sealing level 39 at the latest after the water is taken over during its diversion from the drainage profile 14 into the hollow chamber 16 the sealing plane 39 towards the outside of the rotating wing 1 is overcome. From here on, the water flows in a plane parallel to the wing. 5 oriented plane along the hollow chambers of the wing profiles 6, 7, 8, 9 guided until it finally passed through the drainage openings 33 a lower end of the wing profile 4 exits. This exit of water from the wing profile. 4Therefore, viewed from the inside of the rotating wing 1, it is also located beyond the sealing plane. 39 the wing seal 11 The water is therefore located on an outer surface of the space-defining element. 3, where it cannot cause any damage.

[0073] As can be seen particularly well from Figure 7 In the example shown, the wing frame is... 4 by means of two sealing levels 39, 40 compared to the fixed frame 12 sealed. The first sealing layer 39 is achieved through the interaction of the wing seal 11 with the fixed frame 12 provided. It forms the outer sealing level 39. In contrast, the second sealing level is located 40, parallel to the first sealing plane 39 as well as the wing plane 5oriented in a direction perpendicular to the wing plane 5, viewed on an inner side of the pivot wing 1. The second sealing plane thus forms the inner sealing plane. 40. The wing frame acts in this regard. 4 with a fixed frame 12 connected frame seal 30 together. This frame seal 30 is comparable to the wing seal 11 formed from a rubber-like material and attached to a respective overhang 38 of a respective frame profile 43, 44, 45 arranged differently than the wing seal 11 is the frame seal 30 not formed in a self-contained manner, as it is located in the area of ​​the threshold 32 has no section. This is particularly evident from the following: Figure 8 .

[0074] In the example shown, the drainage profile 14 preferably with two legs inclined relative to each other 21, 22trained. This is particularly evident from the following: Figure 10 . The first thigh 21 extends within a first level 19, during the second leg 22 on a second level 20 extends. The two levels 19, 20 are oriented here, and preferably in such a way relative to each other, that together they form an angle 23 enclose at approximately 60°. The two legs 21, 22 are connected to each other at their facing ends or merge into one another, thus creating the channel shape of the drainage profile. 14 This results in the first leg. 21 is shorter than the second leg 22. When the drainage profile is aligned as intended 14 is the first level 19 vertical or parallel to the wing plane 5 oriented towards one of the second limbs. 22 far outside of the first leg 21Here, and preferably, is an adhesive strip. 17 applied, by means of which the drainage profile 14 especially easy with the upper horizontal wing profile 6 It can be connected. Here, and preferably, is the drainage profile. 14 using the adhesive strip 17 with a flat contact surface 18 of the upper horizontal wing profile 6 connected. On the second leg 22 is on one of the first thighs 21 The underside facing away has a flat contact surface. 36 trained, with the drainage profile 14 on a corresponding surface of the upper horizontal wing profile 6 can be set up, or rather, has been set up.

[0075] The oblique orientation of the second leg 22 referring to the first leg 21 This has the effect, firstly, on the drainage profile. 14falling water along the second leg due to the action of gravity 22 in the direction of the first leg 21 facing end of the second leg 22 is guided. Secondly, the orientation of the second leg results in 22 a guiding function for a drilling tool for creating the breakthroughs described above 28, 29. Therefore, when installing the drainage profile 14 It is particularly easy to correctly align each drill bit to create the desired hollow chamber. 16 of the upper horizontal wing profile 6 to "hit" the target. For this, the drill bit is only attached to the second leg. 22 of the drainage profile 14 to create or parallel to the second level 20 to set up and then put into operation. The desired axis 34 of the breakthrough 28, 29,The area along which it is to be produced is parallel to the second level 20 oriented. Accidental drilling into the "wrong" cavity of the upper horizontal wing profile. 6 This avoids the material of the upper horizontal wing profile. 6, that in the course of making the breakthrough 29 is removed, is in Figure 9 Shown hatched.

Method for draining water in a space boundary element (3) according to claim 12, characterized by the fact thatWater that manages to overcome the seal between the upper section (41) of the wing seal (11) and the fixed frame (12), despite the presence of the rotating wing (1) in its closed position, is collected by means of the drainage profile (14) arranged below the upper section (41) of the wing seal (11), is directed from this into at least one hollow chamber (16) of the upper horizontal wing profile (6) and is discharged within this hollow chamber (16).

14. Method according to claim 13, characterized by the fact that the water is guided through, preferably structurally identical, hollow chambers of different wing profiles (6, 7, 8, 9) which are firmly connected to each other to form the wing frame (4) of the pivoting wing (1), until the water finally exits into the environment of the space boundary element (3) through at least one drainage opening (33) formed on a lower horizontal wing profile (9) of the pivoting wing (1).

15. Use of an elongated profile, preferably an extruded plastic profile or aluminum extrusion profile, as a drainage profile (14) for a hinged wing (1) of a vertically oriented room boundary element (3) which opens outwards about a vertical axis of rotation (2), the hinged wing (1) comprising a rectangular wing frame (4) formed by four wing profiles (6, 7, 8, 9) extending in a common wing plane (5) and rigidly connected to one another, a planar infill (10) oriented parallel to the wing plane (5) which is enclosed by the wing frame (4) perpendicular to the wing plane (5), and at least one elongated wing seal (11) attached to the wing frame (4), wherein the wing profiles (6, 7, 8, 9) are each elongated, and wherein the wing seal (11) is provided and configured to ensure that, when the hinged wing (1) is in a closed position,in which it rests against a fixed frame (12) of the space boundary element (3) and closes a space opening (13) bounded by the fixed frame (12), to come into contact with the fixed frame (12) in a direction perpendicular to the sash plane (5) and thereby seal the casement sash (1) against the fixed frame (12) at least against the passage of water, wherein the at least one sash seal (11) - when considering the casement sash (1) in a vertical orientation intended for its intended use - is attached to an upper horizontal sash profile (6) of the sash frame (4) and extends parallel to a profile axis (25) of the upper horizontal sash profile (6), wherein the drainage profile (14) is elongated and channel-shaped and is provided and arranged for this purpose,to be arranged on the upper horizontal wing profile (6) and to extend parallel to its profile axis (25) at least substantially over the entire length of the upper horizontal wing profile (6), wherein the drainage profile (14) is provided and arranged to be arranged on the upper horizontal wing profile (6) such that the drainage profile (14) – when considering the casement wing (1) in a vertical orientation intended for its intended use – is located below the upper section (41) of the wing seal (11), so that water which manages to overcome the seal against the fixed frame (12) provided by the upper section (41) of the wing seal (11) when the casement wing (1) is in its closed position, can fall from the wing seal (11) onto the drainage profile (14), wherein the drainage profile (14) is provided and arranged toat its longitudinally opposite ends each interact with an end cap (15) by means of which the drainage profile (14) is closed at its end against the escape of water, wherein a fluid-flow connection exists between the drainage profile (14) and at least one hollow chamber (16) of the upper horizontal wing profile (6), so that water taken up by the drainage profile (14) can flow from the drainage profile (14) into this hollow chamber (16) and be discharged from the drainage profile (14) via this hollow chamber (16).
