Description

The invention relates to a frame for a window or a door with a sash with a push rod fitting which is displaceable by means of a handle in at least one open position and a locked position, wherein the push rod fitting comprises at least one locking bolt which in the locked state engages in a fastened to a mating frame part bolt receptacle, and a fixed to the frame sensor with a transmitting element and a detection element, which is assigned to form a light barrier, a reflection element.

In practice, a closure monitoring system for a window with a turn-tilt fitting is known, are mounted on the push rods magnetic pins, which cooperate with closing parts, which serve as a contact and status messages to a central monitoring system. An alarm is issued if a window is unlocked. When attempting to forcibly open a window, the existing reed contact is interrupted and an alarm is triggered via the monitoring system.

Furthermore, it is known from practice to detect by means of a light barrier, whether a window is closed or not. The locking state of the window is not detected with the light barrier, which is relatively easy to install and retrofit in a frame-side cutout.

The invention has for its object to provide a frame with a trained as a light barrier sensor of the type mentioned, wherein the sensor can detect multiple states of the window or the door.

According to the invention the object is solved by the features of the independent claims.

A frame for a window or a door comprises a sash frame with a push rod fitting which is displaceable by means of a handle in at least one open position and a locked position, wherein the push rod fitting comprises at least one locking bolt in the locked state in one on a mating frame part engages a fastened bolt receptacle, and a sensor attached to the frame with a transmitting element and a detection element for forming a sensor is associated with the wing frame and the reflection element of the mating frame part and on the push rod fitting a displaceable upon rotation of the handle foil cover is fixed, which is arranged in the open position in front of the sensor such that at least Transmitter element or detection element is covered, and which releases the transmitting element and the detection element in the locked position.

Accordingly, the light barrier detects not only if the window or the door is closed, but also whether a proper locking has taken place. The cover prevents reflection of the visible or invisible light radiation emitted by a luminous element of the sensor of the light barrier designed as a transmitting element to the detection element of the sensor, so that the signal is applied to the sensor, even with an opened window or door is present, since in this state, no reflection of the emitted light radiation takes place to the detection element. In the locked position of the push rod fitting, in which usually in a closed window or a closed door, the closing part cooperates with the counter-closing part, the cover releases the sensor, so the transmitting element and the detection element, so that emitted by the transmitting element light radiation through the Reflection element is reflected to the detection element.

In a refinement, the cover element covers the transmitting element or the sensing element of the sensor in a tilted position of the push rod fitting. Sonach is also in the tilting position, the signal applied to the sensor even with an open window or an open door.

Preferably, the angle-shaped cover member on the one leg has a recess for the locking bolt and the other leg is slidable in front of the sensor. Accordingly, the cover element extends in the longitudinal direction of the casement, wherein the sensor is installed in a cutout on the inside of the casement facing a space, and the leg covering the sensor runs until just in front of a frame-side seal.

Advantageously, the cover has a shadow mask. It is therefore not necessary to completely cover or release the transmitting element or the sensing element by means of the cover, but rather it is possible to reflect the reflected light radiation through corresponding openings of the shadow mask or to cover the transmitting element or the sensing element by such areas of the shadow mask, which have no opening.

Alternatively, a frame for a window or a door comprises a sash with a push rod fitting, which is displaceable by means of a handle in at least one open position and a locked position, wherein the push rod fitting at least a locking bolt which engages in the locked state in a bolt mounted on a mating frame part, and a frame mounted on the sensor with a transmitting element and a detection element, which is assigned to form a light barrier, a reflection element, the sensor is associated with the mating frame part and on the push rod fitting is fixed on a rotation of Griffolive movable holding element with the reflection element, which is aligned in the open position to the sensor such that from the transmitting element emitted light radiation strikes the absorbent support member, and in the locked position so to is aligned with the sensor, that from the transmitting element emitted light radiation strikes the reflection element.

In contrast to the embodiment already described, the sensor is stationary and the holding element with the reflection element by means of the push rod fitting is arranged relative to the sensor displaceable. In the open position of the push rod fitting, the retaining element which does not reflect light, with the exception of the reflection element, prevents the reflection of the light emitted by the transmitting element of the sensor to its detection element. Likewise, the corresponding reflection of the light radiation is ensured in the closed position of the push rod fitting.

In order to avoid unwanted reflection of light radiation through the metallic surface of the push rod fitting, The holding element covers the push rod fitting areawise.

Conveniently, the reflection element is arranged outside the effective range of the sensor in a tilted position of the push rod fitting. Thus, a signal indicative of an open window is applied to the sensor.

For simple and subsequent installation even with an installed frame expediently comprises the cover or the holding element at least one fixable on the locking bolt plate member and / or is formed as a plate. In the plate or the plate member may be a relatively thin plastic or metal plate, which is present in a gap between the actual locking bolt and a push rod cover of the push rod fitting, inserted and can be fixed to a holding lug. Here, the plate or the plate element, which can also be followed by an angle-shaped cover, have a thickness of a few fractions of a millimeter, for example about 0.2 to 0.5 mm. The cover is a kind of slide, which engages the fasteners of the locking bolt and is guided by a rectangular tube-shaped component, wherein the component is glued to a portion of the push rod fitting and arranged stationary. The slider-like cover must not be designed to be reflective and can, for example, interrupt a light barrier as soon as the push rod fitting is not locked.

In an embodiment, the cover or the support member is guided at least with its plate member wide side in a push rod fitting receiving frame groove and secured by a clip connection.

In order to prevent unwanted reflection of the light radiation, the cover and the holding element are not formed reflective. For example, the surface of the cover or holding element can be made matt black.

In a further alternative embodiment, a frame for a window or a door comprises a sash with a push rod fitting which is displaceable by means of a handle in at least one open position and a locked position, wherein the push rod fitting comprises at least one locking bolt which in the locked state in engages a fastened to a frame member part bolt receptacle, and attached to the frame sensor with a transmitting element and a detection element, which is assigned to form a light barrier, a reflection element, wherein on the push rod fitting a pivotable upon rotation of the handle plate mirror is fixed in the Open position deflects the light radiation such that it does not pass from the transmitting element to the detection element, and in the locked position directs the light radiation from the transmitting element to the detection element.

By the use of a mirror which can be pivoted by a displacement of the push rod fitting for deflecting the light radiation, it is, as already explained, possible that no light radiation from the transmitting element comes to the detection element and the sensor is a signal indicative of an open window or an open door, or it is another receiver installed, which deflected the so Receives light radiation and on which another signal can be removed. If the push rod fitting is in the locked position, the correspondingly pivoted mirror directs the light radiation from the transmitting element to the detection element, optionally via the reflection element, so that a signal is applied to the sensor, which indicates a closed and locked window.

In a further embodiment, the mirror is associated with its pivoting a rocker, which is arranged to be stationary on a push rod of the push rod fitting and the other relative to the push rod.

Conveniently, the cover or the support member or the mirror is arranged in a fold of the sash.

In order to avoid the arrangement of an additional component, the counter-closing part serves as a reflection element. The usually made of a metal counter-closing part is usually provided with a shiny and smooth surface, which is to be used as a reflection surface.

For evaluation and further processing of the sensor data with respect to the closure state of the window and / or the door or the locking state of the handle, the sensor is coupled to a wireless transmission device, wherein the transmission device transmits sensor data to a computer device.

Of course, it is within the scope of the invention, the sensor or its transmitting element displaceable and the cover or the holding element or the mirror are arranged stationary relative thereto. Furthermore, the mirror does not have to be a glass mirror or the like, it is also possible to produce a mirror surface by metallizing or painting a carrier surface with a reflective layer.

The sensor can be housed in a recess or recess of the counter frame part or the sash frame or arranged on any surface.

The mating frame part can be a frame part or a sash frame part of another sash frame, for example a two-leaf window or a two-leaf door, or a fighter.

In the context of the invention it is described that the covering element or the holding element is fastened to a locking bolt. It is known to the person skilled in the art that a push rod fitting fitted with locking bolts can either be bolts, the locking pins in their shape but do not cooperate with closing parts, or mounting options for arbitrarily shaped bolts, screws or the like, wherein both the locking bolt and the bolts, screws or the like, the arrangement of the cover or the holding element is equally possible without the To leave frame of the invention.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations. The scope of the invention is defined only by the claims.

The illustrated frame comprises a frame 1 with a mating frame part 2, on which a counter-closing part 3 with a bolt receptacle 4 is arranged.

Relative to the frame 1 is rotatable or tiltable, a glazing 8 exhibiting wing frame 5 is hinged, comprising a cooperating with a push rod fitting 6 handle. At the push rod fitting 6 locking bolts 7 are fixed, which engage in the locked position in the associated bolt receptacles 4 of the counter-closing parts 3.

In order to monitor whether the window is closed, so that the sash 5 rests in the frame 1, and the sash 5 is locked relative to the frame 1, in the sash 5, a sensor 9 with a transmitting element 21 for the emission of light rays, in particular integrated in the infrared range, as well as a detection element for the reflected light radiation. The light radiation is sent in the direction of the frame 1, in the closed state of the window on a reflection element 10, for example, the Gegenschließteil 3 or a mounted on the frame further reflection element in the direction of the detection element reflected, after which the sensor 9, a corresponding signal with respect to the closure state of Window is present, which is transmitted via a wireless connection to a computer device, such as an alarm system or a home automation system.

Thus, the signaling of a closed window can only take place when the casement 5 is also properly locked against the frame 1, the sensor is associated with a cover 11, the beam path 17 of the light radiation at an open position or tilt position of the push rod fitting 6 interrupts from the transmitting element 21 to the detection element 22, so that a wing frame 5 ajar only to the window frame 1 can not trigger signaling that indicates a closed or locked window.

In a first embodiment, the sensor 9 is inserted into a frame part 12, which with its seal 13 having a free end in the closed state of the window on the frame 1 inside, so room side, rests. The light radiation is emitted perpendicular to a plane of the glazing 8. In the circumferential between the casement 6 and the frame 1 fold 14, in which the locking bolts 7 extend, and the attached to the frame 1 counter-closing part 3 extends to the light radiation of the transmitting element 21 of the sensor 9 strikes.

The angular cover 11 has in its one leg 15, which is aligned perpendicular to the plane of the glazing 8, a recess 16 for fixing to one of the locking bolt 7, which is arranged adjacent to the sensor 9, and extends parallel with its other leg 20 to the plane of the glazing 8, to release the beam path 17 from the sensor 9 to the counter-closing part 3 in the locked state of the window and interrupts the beam path 17 between the sensor 9 and the counter-closing part 3 in the unlocked state.

Fig. 2 the position of the cover 11 can be seen in an open position of the push rod fitting 6, in which the cover 11 is disposed between the sensor 9 and the counter-closing part 3. In a rotation of the handle-olive, the displacement of the locking pin 7 and the push rod fitting 6 in the locked position according to Fig. 3 As a result, also attached to the locking pin 7 cover 11 is moved so that it is no longer between the sensor 9 and serving as a reflection element 10 Gegenschließteil 3 and the beam path 17 from the transmitting element 21 of the sensor 9 to the counter-closing part. 3 and the detection element 22 of the sensor 9 is released. The signal now emitted by the sensor 9 reliably stands for a closed and locked window and can be evaluated accordingly or further processed. It is apparent to those skilled in the art that the cover 11 may be formed as a shadow mask or may include a shadow mask to interrupt the beam path 17 between the sensor 9 and the reflection element 10 or release.

The already explained positions of the push rod fitting 6 with the attached cover member 11 are also the Fig. 7 to 9 to be taken, where Fig. 7 the open position, Fig. 8 the tilting position and Fig. 9 the locked position schematically showing only the relevant closure parts shows.

4 and 5 show the use of the sensor to the formation of the light barrier, the reflection element 10 is assigned in the form of a pivotable mirror 19. The mirror 19 may be arranged like a rocker in the fold and its pivoting on the one hand to the push rod fitting 6 and the other to be fixed relative to the movable push rod fitting 6 on the associated frame member 12. Upon rotation of the handle leaf in the open position of the push rod fitting 6, the mirror 19 is pivoted into a position such that it deflects the light radiation emitted by the transmitting element 21 of the sensor 9 in such a way that it does not reach the detection element 22 of the sensor 9. If the push rod fitting 6 is in the locked position, then the mirror 19 is pivoted in such a way that the light radiation is conducted from the transmitting element 21 to the detection element 22. in both positions of the push rod fitting 6, it is necessary that the sash 5 abuts against the frame 1, to generate on the sensor 9, a signal indicative of a locked and locked window.

It will be apparent to those skilled in the art that, particularly when using the pivotable mirror 19, the light may be directed through the fold 14 both parallel and perpendicular to the plane of the glazing 8.

To Fig. 6 the sensor is attached to the frame 1 and the push rod fitting 6 is associated with a holding element 18, having the reflection element 10. The holding element 18 is provided with a non-light-reflecting surface and the reflection element 10 is either fixed on the holding element 18 or formed by a corresponding surface treatment as a reflective surface. The plate-shaped holding element 18 has a size for covering the push rod fitting 6 in the region of the sensor 9 or the light radiation emitted and received by the sensor 9 in order to avoid unwanted reflection which is not caused by the reflection element 10. In the closed position of the push rod fitting 6, the light radiation emitted by the transmitting element 21 of the sensor 9 strikes the reflection element 10, which reflects the light radiation to the detection element 22 of the sensor 9, at which the corresponding signal can be tapped or sendable. If the push rod fitting 6 is not in the locked position, that is to say in the open position or the tilt position, the light radiation emitted by the transmitting element 21 of the sensor 9 strikes the non-light-reflecting surface of the holding element 18 and a sensor is applied to the sensor Open window corresponding signal to the further processing, such as all signals from the sensor 9, to the computer device, such as an alarm system or a home automation system, is transmitted.

In order to mount the cover element 11 or the holding element 18 with a small amount of space, it has at least one very thinly configured plate element 23, such as the one 10 and 11 to is on or is designed as a thin plate 24, which is a hole pattern 29 depending on the installation situation of the cover 11 or the support member 18 or the sensor 9 to make. Of course, it is also possible to fasten or form reflection elements on the plate 24, or the plate 24 merely serves as a cover of the sensor 9 designed as a light barrier in a specific locking position of the push rod fitting 6.

The plate element 23, which is a quasi kind of head part for the cover element 11 or the holding element 18, or the plate 24 is designed for fastening by means of a clip connection and has a V-shaped inlet bevel 25 with an adjoining undercut 26. The determination takes place in a gap between the mushroom bolt 27 formed as a locking bolt 7 and a cover of the push rod fitting 6. Broadly, the plate 24 and the plate member 23 in a push rod fitting 7 receiving frame 28 is guided.
