Description

The invention relates to a window or door ventilation element for opening and closing a ventilation gap formed in the area of a window or door seal or a sash overlap seal between a frame or blind frame of a window or a door and a window or a door adjacent there, the component an air flow path leading through a window rebate of the window or a door rebate of the door, wherein the window or door ventilation element comprises a sealing slide, a base plate, a guide plate and an actuating element, and wherein the sealing slide is in a sealing plane arranged between the base plate and the guide plate in a Transverse direction of the window or door ventilation element, which runs transversely, in particular perpendicularly, to the longitudinal direction of the window or door ventilation element, is slidably mounted along at least one first guide element.

Furthermore, the invention is aimed at a window or a door that has such a window or door ventilation element.

In order to ensure sufficient fresh air, apartments must be ventilated regularly. Therefore, window or door ventilation elements have been created that are built into the window or door rebate or that are subsequently attached to the outside or inside of the window or door leaf or that are attached to the window or door frame and that have an air flow path leading through the window rebate form the inside to the outside or from the outside to the inside and thus enable an exchange of air. Many of these systems are intended to be retrofittable items. Window or door ventilation elements that are arranged in the window or door rebate are usually equipped with a pendulum flap that automatically opens and closes the air flow path leading through the window rebate. In addition, window or door ventilation elements are known which are mounted as sash rollover ventilators on the edge of the sash of a window or door or on the window or door frame and which usually have a manually adjustable sealing slide with which in the area of a window or door seal or a sash overlap seal, a ventilation gap formed between the window or door frame and the adjacent window or door can be covered, which is part of the air flow path leading through the window rebate of the window or the door rebate of the door.

A window or door ventilation element that is arranged in the rebate between the sash and the frame of a window or door and that has a pivoting pendulum flap, which regulates the volume flow along the ventilation path in the window or door fold is from the DE 199 29 133 A1 known.

Window or door ventilation elements that have a manually operable sealing slide, which is designed to be pushed out transversely to the longitudinal direction of such a window or ventilation element and pulled back into it EP 1715133 B1 and the EP 2 987 939 B1 known. A sealing slide is described there, which is arranged on the sash of a window or door and then engages in the sealing area of the sash overlap seal between a window sash and a window frame, with an opening in the sash overlap seal being provided at this point, which can be closed by the sealing slide is. The sealing slide is arranged on a window or door leaf so as to be displaceable in the direction of flow of the air flow path formed in the area of the casement overlap seal.

Here, the sealing slide after the EP 2 987 939 B1 by moving the sealing slide in the longitudinal direction of the window or door ventilation element out of and back into the latter by means of obliquely running slot openings formed in the sealing slide.

In the generic seal slide after EP 1 715 133 B1 This is moved out of and back into the window or door ventilation element perpendicularly and transversely to the longitudinal direction of the window or door ventilation element by means of elongated hole openings in the sealing slide that run perpendicular to the longitudinal direction of the window or door ventilation element.

The disadvantage of these window or door ventilation elements that can be manually adjusted and set to regulate the volume flow is that they cannot be installed in a window or door rebate because they cannot be reached by hand when the window or door is closed. They are therefore only used as so-called window rebate ventilators, which are mounted on a window sash or door sash. In many cases, however, it is desirable to be able to adjust the air flow flowing in the window rebate or door rebate by hand.

The object of the invention is therefore to create a solution that provides a window or door ventilation element that is to be arranged concealed in the window rebate of a window or door rebate of a door and that enables a window or door rebate to be formed To open and close the air flow path by manually actuating a sealing slide, the sealing slide being in its position in the window rebate also to be operated manually when the window or door is closed.

This object is achieved according to the invention by a window or door ventilation element according to claim 1. This object is also achieved by a window or a door according to claim 23. Advantageous refinements and developments of the invention are the subject of the respective dependent claims 2-22 and 24.

In the case of a window or door ventilation element of the type described in more detail at the outset, the object is therefore achieved according to the invention in that the sealing slide has at least one second guide element and that in an actuating plane arranged between the base plate and the sealing slide or between the guide plate and the sealing slide an actuating plate is longitudinal at least one third guide element is mounted so that it can slide in the longitudinal direction of the window or door ventilation element, which has at least one engagement element, preferably at least one protruding guide cam, on its outside facing the sealing slide, with the at least one engagement element, preferably the at least one guide cam, of the actuating plate in the at least one second guide element of the sealing slide engages and, when the actuating plate is displaced in the longitudinal direction of the window or door ventilation element, displaces the sealing slide in the transverse direction along the second guide element.

In the case of a window or a door, the object is achieved according to the invention in that at least one window or door ventilation element according to one or more of Claims 1 - 22 is arranged in the window rebate of the window or door, the base plate being immovable on the frame or outer frame of the window or the door is fixed.

The invention creates a window or door rebate ventilator to be positioned in a concealed manner in the window or door rebate, which, by means of an actuating element protruding from the ventilation gap between the window frame or door frame or blind frame and the adjacent window or door sash, can be continuously adjusted manually between a closed position in which an window or door ventilation element is extended and the air flow path in the area of the ventilation gap is closed by contact with the adjoining window sash or door sash in the area of the window or door overlap, and an open position or open position in which the sealing slide is retracted into the window or door ventilation element and releases the ventilation gap, is designed to be displaceable. In this case, an actuating element is moved in the longitudinal direction of the window or door ventilation element parallel to the window or door frame and this movement in the window or door ventilation element is converted or deflected or transformed into a movement of the sealing slide transversely, in particular perpendicularly, to this displacement direction of the actuating element.

The invention therefore makes use of the knowledge that it is expedient and advantageous to form both a sealing plane occupied by a sealing slide and an actuation plane occupied by an actuation plate separately in the window or door ventilation element and then to make a displacement movement in the actuation plane in the longitudinal direction of the window or door ventilation element and in the sealing plane to allow the sealing slide to execute a displacement movement in a transverse direction oriented transversely to the longitudinal direction. It is then possible to arrange the sealing level with the sealing slide in the area of a window or door rebate and to extend the operating level by means of an operating element to a window or door sash that is no longer in contact with the window or door rebate and outside of the window or door sash to extend the door rebate lying area. Due to the separation of the actuating level/actuating plate and the sealing level/seal slide according to the invention, it is possible to create a translation - here in particular in the form of a second guide element (second slot opening) configured diagonally to the longitudinal direction L of the window or door ventilation element - which Seal slide required actuation path in the direction of the longitudinal direction L designed / formed significantly longer than it corresponds to the actual sealing path of the seal slide between its open position or opening position and its closed position. As a result, the open position of the sealing slide can be set much more sensitively and better in intermediate positions than would be possible with a displacement movement that is only possible in the transverse direction Q of the window or door ventilation element, since these only allow a small displacement movement over a maximum of the width X of the ventilation gap would.

In order to implement the above knowledge, it is expedient in an embodiment of the invention if the at least one first guide element is a first slot opening, which extends in the transverse direction of the window or door ventilation element and preferably perpendicular to the longitudinal direction of the window or door ventilation element.

It is also expedient to implement the above knowledge in the embodiment of the invention if the at least one second guide element is a second slot opening which is formed obliquely, preferably diagonally, both to the longitudinal direction of the window or door ventilation element and to the transverse direction.

Furthermore, it is expedient to implement the above knowledge in the embodiment of the invention if the at least one third guide element is a third slot opening which extends parallel to the longitudinal direction of the window or door ventilation element in the actuating panel.

Furthermore, the base plate or the guide plate can have at least one guide dome, which engages in the at least one first guide element, preferably the at least one first slot opening, of the sealing slide, with the at least one guide dome holding the at least one first guide element, preferably the at least one first slot opening, of the Passes through the sealing slide and engages in the at least one third guide element, preferably the at least one third slot opening, of the actuating plate.

In a further embodiment, the invention provides that the at least one engagement element, preferably the at least one guide cam, engaging in the at least one second guide element, preferably the at least one second slot opening, of the sealing slide, when the actuating plate moves in the longitudinal direction of the window or door ventilation element in the at least one second guide element, preferably the at least one second slot opening, of the sealing slide slides and moves the sealing slide in the transverse direction (Q) of the window or door ventilation element.

Provision can also be made here for the at least one guide dome engaging in the at least one third slot opening of the actuating plate to prevent the sliding movement of the actuating plate in the longitudinal direction of the window or door ventilation element by means of a respective stop on one of the opposite slot ends of the at least one third slot opening between a left and limited to a right stop position.

It can also be provided that the at least one guide dome, which passes through the at least one first slot opening of the sealing slide, supports the sliding movement of the sealing slide in the transverse direction of the window or door ventilation element by a respective stop at one of the opposite slot ends of the at least one first slot opening between a retracted and an extended stop position of the sealing slide.

An advantageous further development of the invention is that in the guide plate or base plate that has the at least one guide dome, at least one guide groove is formed, which extends in the longitudinal direction of the window or door ventilation element and accommodates the at least one engagement element, preferably the at least one guide cam, which preferably parallel to the at least one third slot opening of the actuating plate and which preferably limits the sliding movement of the actuating plate in the longitudinal direction of the window or door element in a left-hand and a right-hand stop position by the guide cam striking one of the opposite ends of the guide groove.

Expediently, the slot end of the at least one first slot facing a front edge of the sealing slider is at such a distance from the front edge that the material surface of the sealing slider remaining between the slot end and the front edge is sufficient to cover the width of the area of the window or door seal or the sash overlap seal between the To cover the window or door frame and the adjacent window sash or door sash, which is part of the air flow path leading through the window rebate of the window or the door rebate of the door, which the invention also provides in an embodiment.

A further advantageous embodiment of the invention is that the sealing slide can be adjusted in the transverse direction of the window or door ventilation element between a retracted, maximum open position that at least largely opens up the air flow path in the ventilation gap and an extended closed position that closes the air flow path in the ventilation gap.

In particular, however, the window or door ventilation element can be dimensioned in such a way that it can be placed in the window or door rebate in the air flow path.

In order to be able to move the actuating plate manually, it is advantageous if the actuating element is arranged on a front edge of the actuating plate and is in the form of a handling lever which protrudes beyond the window or door ventilation element to such an extent that it is in the air flow path in the window or door rabbet arranged window or door ventilation element extends through the ventilation gap to the outside, which the invention also provides in a further development.

The window or door ventilation element 1 according to the invention, designed as a so-called window rebate ventilator or door rebate ventilator and described below, is installed in the area of a window or door overlap 2 of the window or door sash 4 of a window 3 or a door in the space between the window or door sash 4 and the frame or Frame 5 of the adjacent window 3 or the adjacent door formed window rabbet 6 or door rabbet used. Here, the window or door ventilation element 1 is dimensioned and positioned in such a way that it is arranged essentially on the inside in the area of the window or door rebate 6 and only has a left and a right end element 7a, 7b and one or more contact element(s) 8 protrudes beyond the adjoining frame or window frame side 9 and protrudes into the air duct gap 10, which here in the area of the window or door overlap 2 between the frame or window frame side 9 of the Frame or window frame 5 and the adjacent window or door leaf 4 is formed. In addition, the window or door ventilation element 1 with an actuating element 11, which extends through the ventilation gap 10, extends beyond the window or door flap 2, so that the actuating element 11 can be detected and manually actuated by a user even when the window 3 or door is closed can be. Due to its internal arrangement and positioning in the window or door rabbet 6, the window or door ventilation element 1 or the window rabbet or door rabbet ventilator formed thereby is arranged concealed and only visible when the window or door is swung open. Otherwise, the window or door ventilation element 1 arranged and positioned in the window or door rebate 6 or the window rebate or door rebate ventilator formed thereby is covered by the window or door leaf 4 resting on the frame or frame 5 . In the exemplary embodiment, the window or door ventilation element 1 is fixed in place in the window rebate 6 on the window frame 6 by means of three screws 12 . In a manner not shown, snap-in feet can also be formed on the window or door ventilation element 1 , preferably protruding from a base plate 13 , by means of which the window or door ventilation element 1 can be fixed in the window or door rebate 6 .

The ventilation gap 10 is created by removing a piece of the window or door seal, preferably a sash overlap seal, usually attached to the respective window or door sash 4 in a desired first air passage area 14 . This creates the ventilation gap 10 in this area previously filled by the window or door seal. In order to form an air flow path 16 in the window rebate or door rebate 6, at least a second air passage area 15a is created at another point, which can also be removed by removing the otherwise existing window seal arises. In the embodiment after figure 6 a desired third air passage area 15b is also formed in the same way by removing the window or door seal that is otherwise present there. The air flow path 16 running through the window or door rebate 6 is then formed between the first air passage area 14—and thus the ventilation gap 10 formed by it—and the second and third air passage areas 15a, 15b. The air flow path 16 thus extends in the usual, for example in the EP 1 715 133 B1 and the EP 2 987 939 B1 described manner from the outside A of a window 3 or a door through the window rebate 6 through to the window 3 or the window or door sash 4 interior IN. Since the first air passage area 14 is on the interior side of the window 3 or door and the second and third air passage areas are each on the outside A of the window 3 or door, the air flows along the air flow path 16 between the first air passage area 14 and the second or third air passage area 15a, 15b. The window or door ventilation element 1 is placed in the air flow path 16 in the window or door rebate 6, for which purpose it is dimensioned accordingly.

In the area of the ventilation gap 10, the first air passage area 14 - and thus also the ventilation gap 10 - is delimited laterally on each side by one of the left and right end elements 7a, 7b arranged on the window or door ventilation element 1, in the exemplary embodiment on the base plate 13. When the window 3 or door is closed, these closing elements 7a, 7b rest in the ventilation gap 10 on the inner side 17 of the adjoining window or door leaf 4 facing the ventilation gap 10 . The first to third air passage areas 14, 15a, 15b are formed by cutting and removing the existing window or door seal without having to perform milling work or the like on the window or door frame 5 or on the window or door leaf 4 in this area.

The contact elements 8, which are arranged on the front edge 18 of the window or door ventilation element 1, in the exemplary embodiment the front edge 25 of the base plate 13, from which the left and right closing element 7a, 7b also protrude, form stops for the window or door ventilation element 1 to rest against the frame or window frame side 9 at the edge in the transition to the window or door rabbet 6. The same types of stops form on the front edge 18 of the window or door ventilation element 1 and the left and right closing elements 7a, 7b with their respective areas 19a, 19b also protruding upwards.

The window or door ventilation element 1 consists, as is particularly the case 1 and 2 can be seen from the base plate 13, an actuating plate 20, a sealing slide 21 and a guide plate 22, with the sealing slide 21 being arranged between the guide plate 22 and the actuating plate 20 and mounted in a slidable manner and the actuating plate 20 between the base plate 13 and the sealing slide 21 arranged and slidably mounted.

The base plate 13 forms an area between the two closing elements 7a, 7b, which is in the in the Figures 5a and 5b shown positioning of the window or door ventilation element 1, in which the closing elements 7a, 7b rest on the closed window sash 4, between the two closing elements 7a, 7b forms a slot-shaped opening 23, in the area of which in the installed position of the window or door ventilation element 1, the window seal or window rebate seal is removed and the ventilation gap 10 and part of the air flow path 16 is formed as a result. The base plate 13 has side walls 24a - 24d on its side edges and on its rear longitudinal side opposite the slit-shaped opening 23 and on its upper side, whereas the front area adjoining the slit-shaped opening 23 or the front side adjoining the slit-shaped opening 23 and the underside of the Base plate 13 are formed without a respective side wall and thus open. The base plate 13 thus forms a housing that is closed on several sides or is a component of such a housing.

The sealing slide 21 has three longitudinally L of the window or door ventilation element 1 arranged distributed evenly over its longitudinal extent first slot openings 26, each first slot opening 26 forming a first guide element 26a. The first elongated hole openings 26 extend in the transverse direction Q of the window or door ventilation element 1 and are oriented perpendicular to the longitudinal direction L of the window or door ventilation element 1 in the exemplary embodiment. A second slot opening 27 is formed centrally and symmetrically between each two first slot openings 26 in the sealing slide 21 viewed in the longitudinal direction of the window or door ventilation element 1, each of which extends obliquely both to the longitudinal direction L of the window or door ventilation element 1 and to the transverse direction Q is formed extending diagonally. Each slot opening 27 forms a second guide element 27a.

The guide plate 22 has three guide domes 28 distributed evenly over its length in the longitudinal direction L of the window or door ventilation element, which protrude from a top side of the guide plate 22 in such a precisely positioned and congruent manner as each first slot opening 26 of the sealing slide 21 that they each enter a first slot opening 26 of the seal slide 21 engage. In addition, the guide domes 28 each extend through a first elongated hole opening 26 of the sealing slide 21 . A guide groove 32 is formed centrally and symmetrically between each two guide bosses 28 in the guide plate 22, which extends both in the longitudinal direction L of the window or door ventilation element 1 and parallel to the extension of third elongated hole openings 31, which are formed in the actuating plate 20. In this case, every third slot opening 31 forms a third guide element 31a. In addition, viewed in the longitudinal direction L of the window or door ventilation element 1 , it is centered and symmetrically in the intermediate space between two slot openings 26 of the sealing slide 21 , each of which is assigned to a first slot opening 26 Guide domes 28 each have a second slot opening 27 in the sealing slide 21 .

In the base plate 13 there are three screw holes 36 each assigned to a guide dome 28 . The window or door ventilation element 1 can be fixed in place in the window or door rebate 6 by means of screws 12 guided through a guide dome 28 and a screw hole 36, with the base plate 13, the actuating plate 20, the sealing slide 21 and the guide plate also being connected by means of this screw connection 22 are kept in their superimposed position, in the embodiment in their in the Figures 3 and 4 shown superimposition are held.

The actuating plate 20 has two guide cams 30 protruding on its underside or outside 29 facing the sealing slide 21 and three third elongated hole openings 31 . Here, each guide cam 30 forms an engaging element 30a. The guide cams 30 are distributed evenly over the longitudinal extent of the actuating plate 20 and are arranged in such a precise position and congruently with each second slot opening 27 of the sealing slide 21 that each guide cam 30 engages in each second slot opening 27 and extends through it. The guide cams 30 are also positioned precisely and congruently with a guide groove 32 of the guide plate 22 in such a way that each guide cam 30 engages in a guide groove 32 receiving it after passing through a respective second slot opening 27 . The guide grooves 32 are aligned parallel to the third slot openings 31 of the actuating plate 20 and preferably limit a sliding movement of the actuating plate 20 in the longitudinal direction L of the window or door element 1 in a left and a right stop position by the guide cams 30 striking one of the opposite ends of the guide groove . A guide cam 30 is viewed in the longitudinal direction L of the window or door ventilation element 1, both in the center and symmetrically between two third elongated hole openings 31 in the actuating plate 20 and also in the center and symmetrically in the intermediate space between two guide domes 28 each assigned to a third elongated hole opening 31 in the actuating plate 20 on the Actuating plate 20 arranged.

The third elongated hole openings 31 extend parallel to the longitudinal direction L of the window or door ventilation element 1 and are also distributed uniformly over the longitudinal extent of the actuating plate 20 in such a precisely positioned and congruent manner to a first elongated hole opening 26 of the sealing slide 21 and a respective guide dome 28 of the guide plate 22. that they each have one in their longitudinal extent associated first elongated hole opening 26 and sweep over the respective one associated guide dome 28 , each guide dome 28 engaging in a third elongated hole opening 31 after passing through a first elongated hole opening 26 .

The actuating element 11 in the form of a handling lever 35 is arranged on a front edge 34 of the actuating plate 20 . The operating lever 35 protrudes beyond the window or door ventilation element 1 to such an extent that, when the window or door ventilation element 1 is arranged in the air flow path 16 in the window or door rebate 6, it extends through the ventilation gap 10 to the outside and there in front of the window - Or window frame 5 can be reached by hand and can be actuated manually. In the window or door ventilation element 1, the actuating plate 20 is guided in an actuating plane arranged between the base plate 13 and the guide plate 22, in the exemplary embodiment in an actuating plane formed between the sealing slide 21 and the base plate 13, by means of the guide domes 28 in the third elongated hole openings 31 slidably mounted in the longitudinal direction L of the window or door ventilation element 1 .

The sealing slide 21 is guided in the window or door ventilation element 1 in a sealing plane also arranged between the base plate 13 and the guide plate 22, in the exemplary embodiment in a sealing plane formed between the actuating plate 20 and the guide plate 22, by means of the guide domes 28 in the first elongated hole openings 26 in a transverse direction Q of the window or door ventilation element 1, which runs transversely to the longitudinal direction L of the window or door ventilation element 1 and, in the exemplary embodiment, is predetermined by the first elongated hole openings 26 perpendicular to the longitudinal direction L of the window or door ventilation element 1.
