Title: Device for limiting the maximum swing or tilt angle of a window or door leaf

The invention relates to a device for limiting the pivoting or tilting of a window or door leaf to a maximum opening width, wherein the device has a rotatably mounted on a base and selectively in a release position or a limit position transferable latch.

From DE 10 2015 104 047 Al a lock for locking a tilt and / or pivoting window sash in a ventilation position is known. The lock has at least one magnet, which prevents a locked in the ventilation position window sash not, for example, by drafts, unwanted zuschlögt. In one embodiment, the lock on a bolt which is adapted to be fastened by means of a fastener to a window frame. The bolt is fastened to the window frame in such a way that the window sash can be opened and closed undisturbed and a bolt mounted rotatably on the bolt can be moved into the swiveling range of the window sash.

From DE 10 2013 007 191 B3 a door or window security is known. The door or window lock has a holder which fixes on a flat surface next to a door or window sash of a door or window attaching fixed. The door or window lock has a first pivot arm pivotable relative to the bracket and a second pivot arm pivotally connected to the end of the first pivot arm and movable to secure the door or window to a use position in which it fully opens the door - or window sash prevented.

From DE 741 63 73 U a locking bolt for partially openable tilt window is known. The locking bar has a locking frame to be rotatably mounted on the test window frame, which has one or two recesses, one of which in the rotated locking position engages over a side frame of the tilting window and locks it in this position. However, this device does not allow to effect a limitation of the opening width before opening the window sash, whereby the locking bar is not available, or only with very considerable effort, in particular with regard to automated ventilation.

From DE 1 764 109 U is a locking device for tilting and

Turn-wing windows known. The locking device serves to lock a window when ventilating a room. Specifically, the locking device is adapted to cooperate with a cage closure. A crenellated closure consists of a rotary handle arranged on the window frame with a locking lever and one or two locking rods moved by means of this rotary handle, which engage in the top and bottom of the window frame and thus effect a locking of the window. The locking device has a in the path of movement of the locking bar perpendicular to the window frame close above the window frame arranged arm with a plurality of notches, in which engages the locking rod. Disadvantageously, this locking device is limited to windows which are provided with a cage closure. Also, this device does not allow to effect a limitation of the opening width before opening the window sash, whereby the locking bar is not available, or only with very considerable effort, in particular with regard to an automated ventilation.

As far as the known devices are at all suitable for automated ventilation, they have the disadvantage that the opening width of the geometry of the respective window to which the device is attached, is honorable. This has the disadvantage in practice disadvantageous that the opening width for a ventilation process is usually too small or too large.

It is the object of the present invention to provide a device of the type mentioned, which individuel inde pendent of the dimensions and the geometry of the glare and casement! can be used and, in particular for a ventilation process, limiting the pivoting or tilting of a window or door leaf allows for a certain, desired opening width.

The object is achieved by a device which is characterized in that the distance of the bolt to the base is adjustable.

In accordance with the invention, it has been recognized that ventilation, in particular automated ventilation, is particularly advantageous and efficient if there is a specific opening width of the window sash during the ventilation process. According to the invention, it has been found that the optimum opening width in a ventilation process in which the window sash is pivoted about a vertical axis is in the region of 20 mm. At this opening, the ratio of the time required for the ventilation process to the amount of air exchanged is particularly good. The opening width is understood to mean the distance between the free end of the window sash and the part of the window frame on which the free end rests in the closed state.

The device according to the invention advantageously prevents the window sash locked in the ventilation position from being unintentionally opened, for example by wind or an unauthorized third party, beyond the ventilation position.

It has been shown that an opening width in the range of 18 mm to 25 mm, in particular in the range of 19 mm to 21 mm, in particular of 20 mm, has the advantage that in conjunction with the conventional space heating, a good "air intake" erfoigt.

Much smaller opening widths than the mentioned opening width, in particular smaller than 20 mm, have the disadvantage that the venting process takes much too long or, under unfavorable circumstances, even no exchange of the used up fresh air takes place. With an opening width of only 14 mm, the ventilation process can even take several hours to reach a complete air exchange.

A much larger opening width than the mentioned opening width, in particular greater than 20 mm, has the disadvantage that in winter the temperature drop in the room is too great, so that the risk exists that people in the room freeze during the ventilation process until the room has reheated after the ventilation process.

Apart from that, a larger opening width than the mentioned opening width, in particular greater than 20 mm, has the disadvantage that a larger attack surface is offered for burglars, for example, to set crowbars. In addition, a greater opening width than the opening width mentioned, in particular greater than 20 mm, the disadvantage that it can be easily recognized from the outside that a window is not completely closed, but is apparently in ventilation position.

An opening width in the above-mentioned range, in particular of 20 mm, in particular has the very special advantage that the paragraphs and folds present in conventional heat protection windows, which engage in the closed state at an opening width in the above range, in particular of 20 mm, a kind Forming a labyrinth that is too tight for a screwdriver or a crowbar; unlike larger opening widths.

The known devices are, as initially described in detail, usually not suitable for an automated ventilation process anyway. Devices that can be used for a, in particular automate, ventilation process, such as the known from DE 10 2015 104 047 Al lock, have the serious disadvantage that the opening width of the respective geometry, in particular the respective sash hangs. Thus, it may happen that the opening width when using such a fastener on a particularly thin running sash overly large and much too small when used on a particularly thick designed sash to allow the above-mentioned particularly efficient ventilation with optimal opening width.

In a particular embodiment, the base of the device according to the invention comprises an anchoring portion which is designed and intended to be fastened to a window frame of a window or door. For example, the anchoring section may have through holes, through which screws which can be screwed into the frame or block frame can run. In particular, such an embodiment may be designed to be screwed directly to the visible inner side of a blend or block frame. Such a design is particularly robust and easy to assemble. However, there is the disadvantage that the baffle or block frame is damaged on its inside, and in particular the inputs of Schraubrenööle the screws remain permanently visible after removal of the device.

In another, particularly advantageous embodiment, which avoids this disadvantage, the base has an anchoring portion which is adapted to be screwed to the end face of a blend or block frame and with the window closed in the space between the wing and the Blend or block frame arranged isf. In this way, a secure, reliable and reliable attachment is achieved, which avoids that the blend or block frame is visibly damaged from the outside or inside. In particular, it is not necessary to screw screws from the inside in the blend or block frame and to drill the blend or block frame for this purpose from the inside. Rather, the particular embodiment has the advantage that the inside of the blend or block frame remains completely undamaged. It is advantageously exploited here that it represents no problem for the vast majority of users to screw screws in the front-side inner circumference of the blend or block frame, because there are more screws and other components, such as anchoring screws for anchoring the blend or block frame in anyway Masonry, are arranged. In these areas arranged screws for fixing the base are not visible when the window is closed or with the door closed and are not perceived as disruptive when the window or door is open. In that regard, advantage is taken advantage of that the gap between a wing and the blend or block frame leaves enough space for the anchoring section. This in particular in such a way that the window or the door can be opened and closed unhindered despite the anchoring portion.

It should be understood that the term inner side of a blend or block frame means the side facing an interior of a home and / or is visible from an interior of a home.

In a particularly advantageous embodiment, a connecting device is provided which connects the latch to the base, in particular to the anchoring portion of the base.

In this case, it can be provided in particular advantageous that the length of the connecting device is adjustable in order to achieve adjustability of the distance of the bolt relative to the base.

For example, at least one spacer may be present, wherein the length of the connecting device is adjustable by inserting or omitting the spacer element. Particularly advantageous and versatile is an embodiment in which a plurality of spacer elements are present, wherein the length of the connecting device is adjustable in that a different number of these plurality of spacer elements can be inserted. Alternatively or additionally, it can also be provided that a plurality of spacer elements of different lengths are present, wherein the adjustability is achieved in that at least one of the different-length spacer elements or even a plurality of the spacer elements can be inserted in combination. The spacer element or the spacer elements can be advantageously designed, for example, as spacers. The use of a spacer sleeve has the particular advantage that through the passage of the spacer sleeve through a fastener, in particular a fastening screw, can run, which is described below in more detail.

In a particular embodiment, the connecting device has a first connecting element, the test is connected to the base, and a second connecting element, which is fixedly connected to the latch on. Alternatively, of course, a reverse arrangement is possible in which the connecting device comprises a first connecting element which is fixedly connected to the bolt, and a second connecting element which is fixedly connected to the base.

In an advantageous embodiment, the first connecting element has a pillar with a fastening element. In this embodiment, the second connecting element on a sleeve in which the column is at least partially disposed on. In addition, a counter-fastening element, which cooperates with the fastening element, is present. The fastening element may in particular be an internal thread arranged in the column, into which the counter-fastening element designed as a fastening screw and extending through the sleeve is screwed, whereby the first connecting element and the second connecting element are securely held together. The attachment is preferably, however, such that the bolt remains rotatable relative to the base in order to have this selectively and without the need to solve the attachment in the release position or to transfer the limiting position can.

The sleeve may have an axial end stop inside, on which the free end of the column can abut the front side. It is particularly possible to insert between the end stop and the free end of the column a spacer element or a plurality of spacer elements to adjust the length of the connecting device and thus the distance of the bolt to the base. The inserted spacer elements are preferably also disposed within the sleeve. As already mentioned, the spacer elements may advantageously be designed in particular as spacer sleeves, so that the counter-fastening element can run through the respectively inserted spacer sleeve or the respectively inserted spacer sleeves.

Preferably, the device is designed such that the bolt is rotatable after an adjustment relative to the base in a plane of rotation in the release position or the limit position, but not without a renewed adjustment perpendicular to the plane of rotation. Alternatively or additionally, it may also be provided that, after a setting operation, the bar is rotatable relative to the base within a plane of rotation selectively into the release position or the limiting position, without the distance of the bar from the base being changed by turning the bar. In particular, the plane of rotation may be aligned parallel to an abutment surface of the base which is intended to rest on an inner side of a blind or block frame in the fastened state.

In a particular embodiment, the device according to the invention has no magnet.

In a particular embodiment, a helical gear is present, wherein the distance of the bolt to the base by turning a threaded spindle of the helical gear is adjustable.

The stop element may for example be made of an elastic material, such as rubber or sponge rubber or silicone, and / or be formed as a buffer element. Alternatively or additionally, it is also possible that the stop element has a spring. In such an embodiment, the stop element prevents the window sash or the door leaf from causing a noise when it hits the bolt or even becoming damped. This is particularly advantageous when the opening and closing of the window sash is accomplished in the context of automated ventilation of a machine.

In a particular embodiment, the stop element by means of

Helical gear can be moved relative to the rest of the bolt to adjust the distance of the bolt to the base. In another embodiment, a threaded spindle of the screw thread connects the latch to the base. Particularly robust is an embodiment in which a threaded spindle of the screw thread is operatively connected both with the bolt, and with the base.

In particular with regard to automated ventilation, an embodiment of the device according to the invention is of particular advantage, in which the bolt can be transferred into the limiting position even when the window is completely closed or the door is completely closed. In this way, a limitation of the pivoting or tilting of the window or door leaf can be made to a maximum opening width, without having to open the window and without further changes in the device or the adjustment of the device are required. Such a design haf the particular advantage that the bolt can not be converted into its limiting position not only after unlocking the window sash or even after a transfer of the window or door sash in the ventilation position. As a result, it is advantageously avoided with regard to an automated ventilation that a corresponding switching operation of the bolt must be made zusötzlich after the respective opening of the window of a machine. Rather, the bolt, as long as the user does not want to open the window or door completely, always remain in the limiting position, so that the machine can only transfer the window or door wings for ventilation in the open position and then close again without pressing the latch to have to.

Of particular advantage is a ventilation system having a motorized pivot drive for transferring a hinged window sash in a ventilation position and at least one device according to the invention. In particular, the pivot drive can be designed to convert the window or door leaf after a venting process again in a closed division. In particular, two or more devices according to the invention may be mounted on a window or a door.

Also of very particular advantage is a window having such a ventilation system or at least one device according to the invention.
