Description

The invention is directed to a window or door ventilation element with at least one aeration volume flow in the window or Türfalz influencing ventilation element comprising a sealing slide, with which a formed in the sealing region of the wing flash seal air flow path is closed, wherein the window or door ventilation element a base plate with at least having two on one of its longitudinal sides projecting boundary webs, which are in the ventilation flow path forming sealing region of the sash gasket or Fensterfalzdichtung between window or door and window or Türblendrahmen be positioned engageable and form one or more slot-shaped opening (s) therebetween, and that on the base plate of the sealing slide in the direction transverse to the flow direction of the formed in the sealing region of the wing flap seal or Fensterfalzdichtung air flow weges between a maximum opening position and the air flow path occlusive closure position is adjustably arranged, wherein the sealing slide plate-shaped and slidably mounted between the base plate and an upper guide plate, wherein the base plate or the upper guide plate screw and / or guide domes, which in slot openings engage the seal slide.

Furthermore, the invention is directed to a ventilation system comprising at least one such window or door ventilation element in combination with at least one arranged in the air flow path and an air guide chamber and formed in the form of a pivotally mounted flap flow limiter exhibiting Fensterfalzlüfter.

Such window or door ventilation elements and Fensterfalzlüfter have been created to provide an air exchange between an interior and the outside environment. The window or door ventilation elements and Fensterfalzlüfter be in the window or Türfalz of windows or doors (see said outside wall air passages ALD) installed or subsequently attached outside or inside the window or door and open or close a from inside to outside or from outside to inside through the respective Fensterfalz leading air flow path. Many of these systems are designed as retrofittable elements and are designed so that the minimum ventilation can be carried out automatically with them. For this purpose, these ventilation elements are usually equipped with a pendulum flap. In order to be able to subsequently form, in addition to the minimum ventilation, a so-called basic and / or demand ventilation (see ventilation standard DIN 1946-6) on existing windows, a multiplicity of such elements would have to be provided on a window frame, the ventilation then being provided in the window frame Usually can not be set specifically, as an automatically regulating pendulum flap is provided for flow limitation. Also, these known, retrofitted ventilation elements often have a design and size, which only allows them to be mounted on the frame or the wing of a window or door in the upper transverse region of the window or the door when mounted. If you were to attach these, for example, in the lower transverse region or on the side on which the pivot hinges are arranged, the window or the door could no longer tilt or pivot in its open position, since the ventilation element would hinder this due to its size.

It is therefore in the EP 1 715 133 B1 a generic window or door ventilation element has been proposed, which allows easy retrofitting of common Außenwanddurchlässe occlusive windows and / or doors with a Wohnungsbelüftungselement, the ventilation element without affecting the mobility of the respective window or the respective door on each side of a window or door leaf or a window or door frame can be attached. In this window or door ventilation element a sealing slide is moved vertically and transversely on a base plate, so that in the region of the window or door ventilation element in the circumferential Fensterfalzdichtung open air flow path by means of the sealing slide is sealingly closed. A disadvantage of this known window or door ventilation element is that this can only be moved perpendicular to the respective window sash to which it is attached, by means of a pulling or pushing movement. This can be particularly problematic when the window or door ventilation element is arranged on the top of a window sash or door leaf and possibly not easily accessible.

The invention is therefore an object of the invention to provide a solution that allows a simplified and improved opening and closing of a generic window or door ventilation element.

In a window or door ventilation element of the type described in more detail, this object is achieved in that the base plate has at its side edges not having the guide webs side walls and in cooperation with the upper guide plate a three-sided at least substantially closed housing with one of a handle element of Sealing slide to the outside penetrated slot forms and that the slot openings are arranged obliquely to the longitudinal axis and the transverse axis of the base plate and the sealing slide, that by means of a sideways movement of the handle member, the sealing slide is movable in an oblique sideways forward movement from its maximum open position to its closed position ,

By means of the invention it is possible, in the installation position of the window or door element on a window or door leaf, to effect the transverse movement of the sealing slide towards and away from the window seam vent for closing or opening a window rebate gap in the window rebate seal or window flashover seal a laterally acting and / or attacking force acts on the sealing slide. The present invention provided oblique sideways forward movement of the sealing slide from its maximum opening position to its closed position and, if desired, back again can therefore be achieved by a force acting laterally and along a longitudinal edge of the base plate of the window or door element. This allows it For example, as is also the subject of a subsequent sub-claim, that engages a pull cord connection on each side of the handle member. If the window or door ventilation element is now arranged on the wing flap of the upper transverse spar of a window sash, can be arranged on the handle element in each case over the upper part of the window sash, for example on both sides in the transition from the transverse spar to a respective adjacent vertical longitudinal spar of the window deflecting elements the respective Zugschnurverbindung deflected and placed on the usually vertically arranged longitudinal beams of a window sash. It is then possible for a user in a simple manner, even when a window or door ventilation element is arranged on a window sash above in the area of the window rollover, to open or close it by pulling on a string connection guided laterally on a longitudinal window spar. It is therefore no longer necessary to grip the top of the window sash, so that with the solution according to the invention a simplified and improved opening and closing of the window or door ventilation element is achieved.

In an embodiment, the invention provides that the base plate and the upper guide plate, which form the housing, and the sealing slide are dimensioned in their longitudinal and width extension and matched to one another, that the sealing slide in the housing sideways-forward from its maximum opening position in its closure position is movable while its the boundary webs facing sealing edge always extends along the extending between the two outer boundary webs one or more slot-shaped opening (s) and this covers completely or partially in each closed position.

By this configuration it is ensured that the sealing slide within the housing finds the necessary for its sideways forward movement freedom and movement spaces, while ensuring that the sealing slide necessary for the formation of the air flow path flow slot in the Fensterfalzdichtung or wing flap seal in the region Window or door ventilation element sufficiently covers and / or covered.

In order to enable the above-described advantageous comfortable operation of the window or door ventilation element, the invention is characterized in another embodiment in that the handle element is connected to a movement linkage or a drawstring connection. The latter can be guided in the described manner via deflecting elements along the two longitudinal struts of a window, so that, if desired, the window or door ventilation element arranged on top of a door or window wing can also be actuated in the lower region of a window or a door. Likewise, a movement linkage can be provided, by means of which the handle element of a window or door ventilation element can be moved into its maximum opening position and its closing position.

Furthermore, it is also possible to connect several window or door ventilation elements with each other to a window or door ventilation system by these next to each other, but possibly also remotely, on different sides of a window or door leaf - be it on transverse or longitudinal beams - are arranged and then connected to a motion linkage or a drawstring connection, which engage on their respective handle element. This allows all interconnected window or door ventilation elements to be moved simultaneously and evenly. The invention therefore also provides that a plurality of window or door ventilation elements are arranged laterally next to one another and, if desired, at a distance from one another on a window or door leaf and their respective grip elements are connected to one another by a movement linkage or a drawstring connection.

In this regard, the invention also provides that on a handle element or on several, in particular by means of a connecting rod, coupled together handle elements along a transverse spar and the adjacent longitudinal beams of a window or door wing tensioned train pull cord transmits traction.

The window or door ventilation system according to the invention can also with an automatically controlling (window) folding fan, such as, for example, sold under the name "Regel-air®" and in the DE 199 29 133 A1 described to be combined into a ventilation system. The Regel-air® is then designed, for example, so that it provides for the fulfillment of the requirements of a minimum ventilation according to DIN 1946-6 and arranged the Flügelüberschlagslüfter invention or on a side edge of a window or door leaf, the requirements of a basic or Demand ventilation according to DIN 1946-6 is fulfilled / fulfilled, without the need to open the window sash or door leaf for ventilation purposes. To form such a ventilation system, for example, one or more window or door ventilation elements according to the invention are placed on the upper cross member of a window and arranged along the lateral longitudinal beams in each case an automatically regulating (window) rebate ventilator "Regel-air®" in the respective window fold. The invention therefore provides for solving the above object according to the invention also a ventilation system, which comprises at least one inventive window or door ventilation element in combination with at least one arranged in Lüftströmungsweg and an air guide chamber and designed in the form of a pivotally mounted flap flow restrictor comprising Fensterfalzlüfter the at least one window or door ventilation element visible on a window or door frame and the Fensterfalzlüfter hidden in Fensterfalz a window or a door is arranged.

This ventilation system is then characterized in an embodiment of the invention in that the at least one window or door ventilation element or more window or door ventilation elements together meet the requirements of a basic or demand ventilation according to DIN 1946-6 and meet the at least one Fensterfalzlüfter or more Fensterfalzlüfter together meet the requirements of a minimum ventilation according to DIN 1946-6.

The window or door ventilation element 1 according to the invention designed as a so-called sash overflow ventilator and described below is placed and screwed in the region of the window rollover, for example at the top, on the edge of a transverse spar of a window sash 2, wherein the boundary webs 3 engage in the gap 5 formed for the frame 4 and rest against the window frame 4 when the window sash is closed. Between the two boundary webs 3, the window fold seal 6 or wing flap seal previously present there has been removed in the region of the gap 5, so that a slot-shaped opening extends between the two boundary webs 3, which is part of the air flow path 7, which is in the usual, for example in the in the EP 1 715 133 B1 described manner extends from the outside 8 of a window through the Fensterfalz 22 through to the voltage applied to the window or window sash 2 9 interior.

The window or door ventilation element 1 consists, as in particular from FIGS. 1a-1c and 2 it can be seen from a base plate 10, a sealing slide 11 and an upper guide plate 12, wherein the sealing slide 11 is disposed between the lower base plate 10 and the upper guide plate 12 and slidably mounted. The base plate 10 forms between the two Begrenzungsstegen 3 an area that in the in the Figures 5a-5c illustrated positioning of the window or door ventilation element 1, in which abut the boundary webs 3 with the window sash 2 closed on the frame 4, between the two Begrenzungsstegen 3 forms a slot-shaped opening 13, in the region in the installation position of the window or door ventilation element 1, the Fensterfalzdichtung. 6 removed and thereby a part of the air flow path 7 is formed. At its side edges and their slot-shaped opening 13 opposite longitudinal side, the base plate 10 is provided with side walls 14a-14b. In which on the boundary webs 3 opposite longitudinal side of the base plate 10 disposed side wall 14b, a slot 15 is formed approximately in the middle, which is penetrated by the handle member 16 of the sealing slide 11, so that the grip member 16 can be detected and actuated from the outside. In the base of the base plate 10 screw holes 17 are formed corresponding to formed in the upper guide plate 12 screw and / or guide domes 18. In the in the FIGS. 5b and 5c shown use position of the window or door ventilation element 1 on the sash 2, the screw and / or guide dome 18 and the respective associated screw hole 17 are each penetrated by a screw which engages in the adjacent sash 2 and thus the window or door ventilation element 1 on the Window sash 2 determines. Also corresponding to the screw holes 17 and the screw and / or guide domes 18 11 obliquely arranged slot openings 19 are formed in the base of the sealing slide 11 with respect to the longitudinal and transverse axis of the sealing slide, which in the FIG. 2 illustrated assembled state of the base plate 10, sealing slide 11 and upper guide plate 12 are penetrated by one of the upper guide plate 12 hercragierenden screw and / or guide dome 18. In this way, a guide of the sealing slide 11 is formed, which allows an oblique sideways forward movement of the sealing slide 11 and causes a force acting on the handle member 16 with laterally aligned along the side wall 14b effect. By "forward movement" is in this case the movement of the sealing slide 11 in the direction of an open position in its closed position, in which the sealing slide 11 rests against the associated frame 14, respectively. From the closed to the open position, the seal slider is moved in opposite sideways-backward motion.

In the FIGS. 4a and 4b is shown how, by means of this arrangement, the sealing slide 11 by a lateral movement in the direction of the arrow 20 from his in the Fig. 4a shown, the slot-shaped opening 13 and thus the air flow path 7 overlapping and closing closure position in his in the Fig. 4b can be moved shown maximum opening position. In the closed position and in the maximum opening position of the sealing slide 11, a screw and / or guide dome 18 abuts in each case at one end of the respective associated slot opening 19. Likewise, the seal slide 11 from the in Fig. 4b shown maximum opening position by a movement or force application in the arrow 20 opposite direction in the closed position and all possible intermediate positions on the way there bring. Except for the penetrated by the sealing edge 21 of the sealing slide 11 side and the slot 15, the window or door ventilation element 1 is formed as a substantially closed housing, but in the side walls 14a and 14c may well still be provided opening slots. In its closed position is the Sealing slide 11 with its sealing edge 21 on the frame 4, so that the air flow path 6 is completely closed, as also in the Fig. 5b is shown.

The Fig. 6 shows in to Fig. 2 analogous representation of the coupling of two inventive window or door ventilation elements 1 to a functional unit as a sash overflow fan. For this purpose, the two window or door ventilation elements 1 with adjacent side walls 14a, 14c are arranged adjacent to each other. In addition, the respective grip elements 16 are connected to each other by means of a connecting rod 23, which is fixed in each case at one end by means of a screw 24 or a similar fastening means to the respectively associated grip element 16 stationary and fixed in position. To the two window or door ventilation elements 10 together in their in the Fig. 7 shown installation and use position on a window frame 2 easily and easily adjusted, along the connecting rod 23, a pull cord 25 is stretched and also fixed by means of the screw 24 to the respective handle elements 16. Furthermore, the pull cord 25 is stretched on both sides of the window or door ventilation elements 1 along the window sash 2 and guided by loop-shaped brackets 26 guided on the cross member and the opposite longitudinal members of the sash 2. At its two ends, the pull cord 25 is in each case provided with a weight 27a, 27b, so that the pull cord 25 is always guided and held tensioned on the bars of the window sash 2. For common adjustment of the two window or door ventilation elements 1, an operator can then detect depending on the desired direction of movement of one of the two weights 27a or 27b and pull it, whereupon then the two coupled by the connecting rod 23 handle elements 16 moves in the appropriate direction and this combination two window or door ventilation elements 1 can be opened or closed.

Analogous to the in Fig. 7 also shown a single handle member 16 may be connected to a movement linkage or a drawstring connection, with which it is possible for an operator, a the Displacement of the sealing slide 11 enabling force to exert on the handle member 16 when the window or door ventilation element 1 in the in the Fig. 5a and 5b shown position as a sash overflow fan on the edge, for example, the upper edge, a window sash 2 or a door leaf is set.
