EP3800318A1 - Device for protecting against water intrusion and door or window provided with such a device - Google Patents

Abstract

The invention relates to a device (1) intended to be arranged on a door (2) or a window of a building for protection against penetrating surface water, which for this purpose is permanently fixed to the outside (4) of the door (2). In order to move from the non-use position to the sealing use position, an actuating element (5) is used to transmit an actuating force (F) to a force-transmitting element (6) that is translationally movable in the actuating direction and thus to a lower profile element (8). As a result, a lower section (9) of the circumferential sealing element (10) is compressed between a bottom surface and the lower profile element (8) and the desired seal is thus achieved. At the same time, however, the actuating force (F) is also transmitted to two lateral profile elements (12) and the associated lateral sections (13) of the sealing element (10) are pressed against a contact surface of the building. The opposite displacement of the lateral profile elements (12) in the transverse direction (18) required for this is achieved by a coupling element (15). For this purpose, the lateral profile elements (12) are each equipped with two parallel inclined surfaces (16), against each of which a rolling element (17) connected to the translationally movable force transmission element (6) rests, so that due to the applied actuating force (F) there is a transverse displacement of the lateral profile elements (12) compared to the translational movement of the force transmission element (6).

Description

The invention relates to a device intended to be arranged or retrofitted on a door or a window of a building, in particular an entrance door of the building, for protection against water ingress by surface water, in particular due to heavy precipitation or flooding, the device being an actuating element for introducing an actuating force on a force transmission element that is translationally movable in the actuating direction for transmitting a pretensioning force compressing a lower section of the sealing element between a bottom surface and at least one lower profile element and at least two lateral profile elements for pressing lateral sections of the sealing element against stationary contact surfaces by shifting the lateral profile elements in opposite directions due to the actuating force introduced has in that the force transmission element is connected to the lateral profile elements by a kinematic coupling element, with there s coupling element has a link guide with an inclined surface and at least one sliding / rolling element rolling or sliding along this inclined surface for displacing the lateral profile elements in the transverse direction with respect to the translational movement of the force transmission element. The invention also relates to a door, including a lifting door or a window, equipped with such a device.

Such a device is already known for protection against floods or rainwater. In a position of use, the movable sealing elements rest against stationary contact surfaces, in particular the door frame and the door sill, and in the withdrawn non-use position allow unrestricted use of the door or window.

In flood-endangered areas, buildings and especially private houses are always endangered by the water masses overflowing the banks or embankments; as the level rises, water first penetrates the cellar through wall openings such as window and door openings and causes considerable damage. Properties in such flood-prone areas are often not provided with insurance cover, or at least insufficiently.

So far, in such disasters, attempts have been made to use sandbags that are placed in the wall opening in the event of acute danger against the water Achieve sealing. However, the protection that can be achieved in this way is insufficient. In the event of prolonged flooding in particular, the water eventually penetrates through the sand.

A wide variety of solutions have therefore already been devised in order to achieve a sealing option that is fast, reliable and adapted to the respective circumstances, in particular the dimensions of the building opening.

For example, from the WO 2006/061 520 A1 a device for sealing a passage opening against ingress of water is known. This consists of a vertical central element arranged between an upper delimitation of the passage opening and a bottom surface, which is adjustable in length by means of a thread and can be loaded with a desired pretension. Two struts arranged in pairs and spread at an acute angle lie laterally against lateral profile elements in order to press the sealing elements against the lateral boundary surfaces of the passage opening. As a result, a portion of the vertical pre-tensioning force is transferred into a horizontal force component in accordance with the angular arrangement of the struts. By means of a lower profile element directly acted upon by the central element, a lower sealing element is pressed against the floor surface, the lower profile element being designed as a sliding guide to compensate for the displacement of the lateral profile elements. By means of the device, a watertight film is arranged in the passage opening in such a way that it enables the flat sealing against an entrance door, the film being supported on the door so that no connection between the device and the door is required. Since the device blocks the passage, it must be completely dismantled when not in use. In addition, the device requires an upper boundary surface of the passage opening as a support surface and abutment for the pressure force required for sealing. Furthermore, the different angles of the struts result in different pressure forces of the sealing elements in different areas according to the vectorial force distribution. The length of the struts must therefore be adjusted individually. The device can thus be used for different passage openings, but requires complex manual positioning.

The EP 3 405 635 B1 already describes a door device for protection against water ingress by surface water, a force transmission element being connected to the lateral profile elements by a kinematic coupling element which has a link guide with an inclined surface and one along this inclined surface having sliding body. This results in a diagonal displacement of the lateral and lower profile elements.

The EP 0 987 624 A1 relates to a blocking element for protection against ingress of water, which can be expanded laterally and pretensioned against a floor surface. A spindle drive that acts on an articulated arm is used for this purpose. In use, the lateral profile elements are moved away from one another by means of the spindle drive until they rest against the respective side walls. As soon as this position is reached, several bolts are actuated and a lower profile element is moved downwards against the ground in order to achieve an effective seal. The lateral profile elements are telescopically connected to one another in the area of their upper and lower frame elements and covered with an elastic cover membrane for sealing.

The WO 2016/066 577 A2 relates to a sealing device for a door or a window with laterally extendable sealing strips to protect against ingress of backwater in external doors, which can be extended laterally via a manually or automatically operated push rod mechanism, whereby a vertical movement can take place at the same time by lowering a lower door seal. A movement in the opposite direction is achieved by means of a clutch having a lever or a gearwheel.

From the GB 1 101 503 A1 a cover plate for a door is known as protection against the ingress of water, which has a three-sided circumferential, compressible or inflatable seal and frame-side counter sealing surfaces.

Furthermore, from the GB 2,369,846 A a device for flood protection with an inflatable sealing tube in the edge-side recess of the door leaf is known.

In the case of flood protection according to GB 2,382,097 A a fluid-filled hose with a constant volume is provided, which is pressed against the lower door lintel and the floor area by a mechanism consisting of pressure rods and pressure distribution rods.

Task of DE 102 52 670 A1 is to find a device for the watertight closure of openings in buildings, which enables a watertight, quickly produced closure of the openings. For this purpose, at least one rubber-elastic hollow body that can be pressurized by a medium, for example air or water, can be inserted into one of the openings and locked in a form-fitting manner.

The DE 20 2009 010 049 U1 relates to a structural unit consisting of a door and an attachment door with a circumferential seal against ingress of water and to a locking device for permanent assembly in the form of two door leaves attached to a frame on different sides, the exterior of which has a circumferential web on the frame side which is inserted into a Groove engages with sealing material.

The DE 103 01 320 A1 relates to a sealing device for the protection of structures from the ingress of water, in which a plate sealing the edge is arranged as a frame to be movable by means of lateral hinges.

With the DE 33 29 829 A1 If necessary, a watertight seal is to be achieved that can be moved easily and easily when not in use. For this purpose, an elastic hollow body is provided as a seal, the interior of which is connected to a pressure medium source via a pressure control device. A water sensor can be assigned to the pressure control device.

The invention is based on the object of creating a device for sealing a building opening on existing doors or windows for protection against precipitation, heavy rain, flooding or the like, which does not restrict the normal use of the door or window in practice and in particular also by inexperienced persons and technical laypeople can be easily transferred from the non-use position to the use position at any time.
Another object of the invention is to create a door or window of this type equipped with such a device.

The first-mentioned object is achieved according to the invention with a device according to the features of claim 1. The further embodiment of the invention can be found in the subclaims.

According to the invention, the lateral profile elements can be displaced exclusively in the transverse direction to the actuation direction of the force transmission element by a respective guide and the lateral profile element and the lower profile element are connected by an angle element which is arranged relatively translationally movable in a respective sliding guide with respect to the lateral profile element and the lower profile element . In this way, according to the invention, a pure transverse displacement of the lateral profile elements is achieved, whereby not only a constant introduction of force and force transmission to the corresponding lateral sections of the Sealing element ensured, but also an undesirable vertical displacement and the associated overcoming of frictional forces along the associated stationary contact surfaces is avoided. The invention is based on the knowledge that on the one hand a vector force distribution of the applied actuating force into a first force component acting on the lower section of the sealing element and a second force component acting on the opposite lateral sections of the sealing element is useful, and on the other hand a lever arrangement in the manner of a parallelogram guide or a scissor lifting element because of the constantly changing proportions of the force components with continued deflection is not useful. In contrast, the coupling element, thanks to its slotted guide, leads to the desired uniform force distribution over the entire adjustment path, with an angle between 30 ° and 60 °, in particular of approx. 45 °, of the inclined surfaces having already proven advantageous compared to the translational movement of the force transmission element. According to one embodiment of the invention, the inclination of the inclined surfaces can also be designed to be adjustable if, for example, the ratio of the pressing force of the bottom section on the bottom compared to the lateral sections of the sealing element has to be varied in order to achieve the desired sealing effect, for example due to different surface properties of the bottom surface and the lateral contact surfaces may be required. In connection with the pressure force, which always acts normally to the sealing surface, an optimal sealing effect can be achieved.

Since the lateral profile elements can be displaced by means of at least one guide in the transverse direction to the translational direction of movement of the force transmission element, a displacement of the lateral profile elements in the actuation direction of the force transmission element is excluded by the guide. For this purpose, the guide has only a single degree of freedom as a translational movement. As a result, the lateral profiles between the non-use position and the use position of the device can only be moved transversely to the main extension of the lateral profile elements and to the sealing surface and transversely to the translational direction of movement of the force transmission element. On the basis of this defined movement path, an additional form-fitting fixation or a projection connected to the profile element, which engages in an opening in the lateral contact surface, can also be implemented without any problems.

In this case, a lateral profile element and a lower profile element are each connected by an angle element which is arranged so as to be relatively translationally movable with respect to the lateral profile elements and the lower profile element. Since the lower profile element for Achieving the desired biasing force is lowered with respect to the floor surface and at the same time the distance between the lateral profile elements and the floor surface in the use position and in the non-use position is unchanged, compensation in the area of the lateral contact surfaces is achieved by the movable arrangement of the angle element, in particular by a Sliding guide, reached. The angle element can have a shape adapted to the contour in the area between the bottom surface and the lateral, stationary contact surfaces, for example also a rounded circumferential contour or else elastically deformable properties.

Due to this defined relative movement of the lower and the lateral profile elements, the device is also, in contrast to the devices known from the prior art, suitable for arrangement on the door or window, so that their functionality and usability in the non-use position of the device are unrestricted remains. As a result, the device according to the invention can be optimally implemented as a retrofit solution, for example in existing entrance doors, and assembly can be carried out without problems even by non-specialists. With this retrofit solution, insurance-specific requirements can also be met in principle, especially in connection with automatic activation. The use of the device is not limited to pivoting doors, but in principle also sensibly possible with sliding doors.

The lower section and the lateral sections of the sealing element are preferably one-piece or one-piece or non-detachable connected to one another, a variant in which the sections are formed from separate molded bodies, which can also have overlapping areas or undercut areas, for example, are included in the inventive concept.

The seal comes about on the one hand in that the sealing element is pressed by the profile elements against the bottom surface and the lateral, stationary contact surfaces. In addition, the pressure-tight seal against a plate-shaped or profile-shaped retaining element must also be ensured, which, if necessary, absorbs the liquid pressure in connection with other elements. This sealing takes place, for example, in that the profile-shaped retaining element is designed as a hollow profile or is formed by parallel plates and the sealing element is enclosed between two spaced apart, in particular parallel, surfaces. While a mobility of the sealing element relative to the retaining element is provided in the non-use position, the compression of the Sealing element in the use position at the same time to a deformation or expansion, whereby the gap between the parallel surfaces is filled in a pressure-tight manner.

Of course, the device is not limited to applications in the field of flood protection. Rather, due to the increasing frequency of extreme weather phenomena in connection with heavy rain, buildings and structures are basically affected in almost all regions, provided that there are low-lying entrance doors or windows. In addition to fixed structures, this also applies to mobile structures and structures that are not intended for residential purposes.

An embodiment has proven to be particularly advantageous in which the lateral profile elements each have a plurality of, in particular flat, inclined surfaces against which at least one sliding / rolling body of the force transmission element rests. This reduces the transmission losses and at the same time ensures a defined transverse displacement. In practice, given the usual dimensions of the lateral profile elements, the main extent of which typically does not exceed 100 cm, two inclined surfaces have proven to be sufficient, it also being possible for more than two inclined surfaces to be provided.

The inclined surfaces are not limited to a flat extension. In a variant, convex and / or concavely curved contact surfaces of the inclined surfaces can be used for the sliding / rolling elements, for example, in order to achieve, for example, an initially rapid transverse displacement and then a shorter transverse displacement path in favor of an increased prestressing force.

The inclined surfaces of the same profile element could have an orientation in opposite directions, in particular at the same angle with respect to the transverse direction to the translational movement of the force transmission element, so that the actuating force also act in the opposite direction on the various inclined surfaces. In this way, a constructive solution that is largely free of external forces can be implemented. In contrast, it is particularly advantageous if the inclined surfaces of a respective lateral profile element are arranged parallel to one another and preferably also the inclined surfaces of various lateral profile elements have a matching angle with respect to the translational direction of movement of the force transmission element. This ensures reliable operation of the device even under difficult environmental conditions.

In a variant, the guide is also inclined with respect to the transverse direction to the translational direction of movement of the force transmission element and forms an acute angle with the orientation of the inclined surface. A parallel orientation of the degree of freedom of movement in the guide and the inclined surfaces is excluded.

According to a further, particularly practical embodiment of the invention, the guide has at least one roller bearing or a sliding bearing in order to reduce possible friction losses and to reduce a deviation from a desired position.

In addition, it is particularly promising if the angle element is connected to the force transmission element by at least two lever arms movably connected by means of a joint, so that in addition to a possibly existing sliding guide through the lever arms, additional stabilization and also compliance with a predefined target position is guaranteed . By means of the lever arms, the angle element is pretensioned in the corner area with a defined pretensioning force, the pretensioning force that can be achieved independently of the pretensioning of the adjacent profile elements preferably being adjustable.

It has already proven to be particularly advantageous if the force transmission element acts on a lever arm of the angle element in the position of use by means of a pressure body and, due to the translational movement of the force transmission element, a force amplification that deflects the angle element is effected according to the principle of a toggle lever. As a result, the desired pretensioning force is transmitted through the force transmission element by means of the lever arms to the angle element, the desired force amplification being achieved at the same time.

Another, also particularly useful embodiment of the invention is achieved in that the actuating force can be introduced by a kinematic coupling with a door lock or window lock or by an electric drive unit, in particular on the basis of a control signal from a control element equipped with a sensor. Since the actuating force is coupled at the same time with the actuation of an existing door or window lock, additional manual actuation elements are not necessary on the one hand, but on the other hand actuation can also take place from a door or window inside facing away from the device so that they are not opened got to. If the door or the window already produces a seal that is not to be neglected and, for example, there is a liquid level on the outside, undesired opening can be dispensed with. An alternative or supplementary, redundant actuation takes place by means of an electric drive unit with preferably its own energy supply, so that the use position is activated without intervention or manual actuation on the basis of measured values recorded by sensors. Such measured values can be determined, for example, by a water level sensor, precipitation sensor or the like, so that timely activation and unrestricted operational readiness are ensured. Activation by wireless remote data transmission can of course also be provided.

The further object of creating a door or a window with improved protection against ingress of water is achieved according to the invention by a device according to at least one of the preceding claims equipped with the door or the window.

In this case, the device is preferably arranged on an outside facing the surroundings, but can, for example, be arranged on the inside to avoid an undesired change in the external appearance. The device can also be equipped with a decorative attachment element.

The fixation can be realized by screw connections, which are guided through drill holes in the door or the window, wherein the drill holes can be limited to an edge area in which the door or the window is often made of solid material. A variant in which the fixation is achieved by several clamps encompassing the door or window can also be implemented. The fastening is preferably carried out in a floating manner in the transverse direction, so that the lateral pressure is transmitted evenly.

In addition, it has also been shown that the device basically makes opening the door or window so difficult that, in the position of use, a significantly improved protection against break-ins can be achieved at the same time. The device can therefore also be activated on the basis of safety-relevant signals regardless of possible precipitation.

A device 1 according to the invention is described below with reference to FIG Figures 1 and 6th explained in more detail. The device 1 is used to improve the protection of an existing door 2 in the Figures 5 and 6th The building 3, which is shown hinted at, against the ingress of surface water, for example from driving rain, and is permanently fixed to an outside 4 of the door 2 for this purpose. To move from the to the Figures 1 and 4 to 6 in the non-use position shown in the Figures 2 and 3 To get to the sealed usage position shown, an actuating force F is transmitted by means of an actuating element 5 to a force transmission element 6 designed as a push rod, which is translationally movable in the actuating direction, whereby a coupling with a door lock having a door handle 7 can be provided for this purpose. The actuating force F is transmitted to a lower profile element 8 by means of the force transmission element 6. As a result, a lower section 9 of the circumferential sealing element 10 is compressed between a floor surface 11 or a door sill and the lower profile element 8 and the desired seal is thus brought about. At the same time, the actuating force F is also transmitted to two lateral profile elements 12, by means of which the assigned lateral sections 13 of the sealing element 10 are pressed against a lateral, stationary contact surface 14 of the building 3. The opposite displacement of the lateral profile elements 12 required for this due to the introduced actuating force F is effected by a coupling element 15 reached, which has a link guide. For this purpose, the lateral profile elements 12 are each equipped with two parallel inclined surfaces 16, against each of which a rolling element 17 connected to the translationally movable force transmission element 6 rests, so that due to the applied actuating force F, the lateral profile elements 12 are displaced in a transverse direction 18 with respect to the translational direction Movement of the power transmission element 6 comes. In order to reliably exclude an undesired displacement of the lateral profile elements 12 in the direction of their longitudinal extent parallel to the stationary contact surface 14, they can be displaced exclusively in the transverse direction 18 to the actuation direction of the force transmission element 6 by a respective guide 28. In practice, in the devices known from the prior art, a leak often arises in the corner area of the lower section and the lateral section of the sealing elements. To counter this problem, according to the invention, the lateral profile element 12 and the lower profile element 8 are connected by an angle element 19, which is arranged to be movable relative to the lateral profile element 12 and the lower profile element 8 in a respective sliding guide 20 in a relatively translatory manner. In addition, the angle element 19 is connected to the force transmission element 6 by two lever arms 22 movably connected by means of a joint 21. Since a pressure body 23 connected to the force transmission element 6 acts on the lever arm 22 connected to the force transmission element 6 by a further joint 24 in the use position, a force amplification that deflects the angle element 19 is created according to the principle of a toggle lever with an effective direction 25 corresponding to the bisector between the lower one Profile element 8 and the lateral profile element 12. The angle element 19 can have a rounded outer circumferential contour, which interacts with a fixedly fixable molded piece 26 with a corresponding negative contour in order to improve the sealing effect.

Furthermore, an electric drive unit 27 can be provided for introducing the actuating force F, which is equipped with a control unit (not shown) and its own electric power supply, so that the position of use of the device 1 is set in particular on the basis of a control signal. For this purpose, the control unit is equipped with a sensor, in particular a rain sensor or a water level sensor for detecting precipitation, water levels, runoff quantities or the like, which transmits corresponding signals to the control unit.

In principle, the force-fit or form-fit holding forces that can be transmitted by means of the sealing elements are dimensioned in such a way that the water load, in particular in the case of a on the outside up to the maximum height of the device of for example 80 cm pending water level, at least to a large extent taken up by the device 1 from a plate 29 and diverted into the fixed structure of the building 3 and the door 2 is essentially not or only slightly loaded becomes. A coupling of the force transmission element 6 to the door handle 7 can be provided for manual actuation.
