Description

Technical Field

[0001] This invention relates to an accessory device for monitoring the closing of windows, doors, or lift-and-slide elements (e.g., lift-and-slide doors or lift-and-slide windows). Background Technology

[0002] Such accessory devices for disabling monitoring are generally known, and for example only, see the accessory device described in German patent application No. 10 2023 133 589.8.

[0003] Such accessory devices for monitoring closure typically have one or more non-contact sensors that monitor different positions of the drive rod, corresponding in this respect to various positions of the associated door or window. These positions are typically tilted, rotated, and locked. In the accessory device described in the aforementioned German patent application, the sensor or the sensor circuit board carrying the sensor, and in particular the battery for powering the sensor, is located in the accessory slot of the associated door or window. Therefore, this accessory device is only suitable for windows or doors where the drive rod device does not rotate around the entire perimeter of the window or door. In other words, the accessory device described in the aforementioned German patent application requires the cover rail to have a free end, in which the sensor circuit board can extend into the accessory slot. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide an accessory device for closing monitoring, which can also be used in windows, doors or lift-pull elements where the accessory slot cannot be used to accommodate sensors for closing monitoring.

[0005] This objective is achieved by a fitting device for windows, doors, and for lifting push-pull elements, the fitting device being characterized by the features of claim 1.

[0006] Specifically, the fitting device according to the invention has a cover rail and a drive rod, by means of which a fitting slot formed in a door or window can be covered, and the drive rod is translatably guided along the cover rail. At least one locking element, such as a locking pin, especially a mushroom-head pin or a roller pin, is fastened to the drive rod, wherein the locking element passes through an elongated opening formed in the cover rail and can be displaced in the longitudinal direction of the elongated opening by manipulating the drive rod.

[0007] According to the invention, a sensor assembly is fastened on the side of the cover rail opposite to the drive rod. This sensor assembly has at least one non-contact sensor, particularly at least one Hall effect sensor, for detecting the position of the locking element—locked position, tilted position, or rotational position. In a top view of the cover rail, the at least one non-contact sensor is located beside an elongated opening formed in the cover rail.

[0008] Therefore, according to the invention, the at least one sensor is neither located in the continuation of the cover rail nor in the continuation of the elongated opening; rather, according to the invention, when viewed along the longitudinal direction of the cover rail, the at least one non-contact sensor is located within the area of ​​the elongated opening, i.e., indeed located to its side. With the fitting assembly mounted on a door or window, the at least one sensor is thus located between the overlap of the door or window frame and the elongated opening formed in the cover rail, so that when the window or door is closed, the sensor does not collide with the strike plate at the fixed frame, which is associated with a locking element capable of moving within the elongated opening.

[0009] Therefore, the at least one sensor is located directly beside and adjacent to the movement area of ​​the locking element, and sufficient space for the locking element must be provided in the overlap gap in any case. Thus, the fitting device according to the invention optimally utilizes the space available in the overlap gap regardless. Therefore, the fitting device can be used even if the overlap gap is occupied by other mounting components, or if it itself provides relatively little space only to accommodate any retrofit components.

[0010] However, the fitting device according to the invention has proven particularly advantageous because its sensor does not occupy any installation space in the fitting slot, thus the fitting device can also be used for windows or doors where the drive rod device rotates around the entire perimeter of the window or door.

[0011] Furthermore, another advantage is that the signals provided by the at least one sensor are virtually indistinguishable with respect to the corresponding drive rod position, because the corresponding signals are directly affected by the locking element. In other words, the locking element has a relatively large influence on the magnetic field monitored by the at least one sensor, meaning that the monitoring signals output by the at least one sensor vary relatively significantly depending on the corresponding drive rod position. This allows for very reliable identification of the corresponding drive rod position—locked position, tilted position, and rotating position.

[0012] The following will examine further embodiments of the accessory device according to the invention, wherein further embodiments may also be derived from the dependent claims, the description of the drawings, and the drawings themselves.

[0013] Therefore, according to the first embodiment, the accessory device may include exactly two non-contact operating sensors, both of which are located beside the elongated opening formed in the cover rail in the manner already described above. In this respect, the two sensors may be spaced apart from each other adjacent to each other in the longitudinal direction of the elongated opening, i.e., spaced apart by the amount of movement of the locking element between the rotational and tilting positions.

[0014] Preferably, in this respect, one of the two sensors is located near the point where the locking element is in the tilted position, while the other sensor is located near the point where the locking element is in its locked position. Therefore, one sensor reliably outputs a signal representing the tilted position, and the other sensor reliably outputs a signal representing the locked position. Alternatively, the rotational position can be detected using an elimination method: if one sensor does not output a signal representing the tilted position, and the other sensor also does not output a signal representing the locked position, then it can be determined by elimination that the component must be in the rotational position.

[0015] It is indeed possible to integrate a permanent magnet into the locking element, thereby allowing the detection of changes in the magnetic field of the permanent magnet by one or more sensors, and thus the detection of the corresponding closed position. However, since the locking element of a conventional transmission rod device can only be modified with such a permanent magnet at a certain cost, according to another embodiment, it can be specified that the at least one sensor is equipped with a permanent magnet, particularly a single permanent magnet, which, viewed in a top view of the cover rail, is also located beside the elongated opening formed in the cover rail. Thus, the at least one sensor is preloaded by the permanent magnet provided thereto, so that (multiple) sensors can detect changes in the magnetic field generated by the permanent magnet, caused by the locking element occupying different positions in the magnetic field depending on the position of the accessory device. Therefore, the at least one sensor detects the magnetic field changes caused by the locking element, thereby enabling the corresponding changes in the magnetic field to be attributed to one of the switching positions in question.

[0016] As mentioned earlier, it is sufficient to equip only two sensors with a single permanent magnet; in this case, according to another embodiment, it can be advantageous to position the single permanent magnet between the two sensors when viewed along the longitudinal direction of the cover rail, so that the two sensors are preloaded by the permanent magnet to substantially the same degree.

[0017] According to another embodiment, the sensor assembly may include a sensor circuit board that carries the at least one sensor, evaluation electronics for the at least one sensor, and / or at least one battery holder for housing a battery for supplying power to the at least one sensor and the evaluation electronics.

[0018] Since it is important for reliable detection of the various positions of the locking elements that the at least one sensor is located beside the elongated opening formed in the cover rail, the sensor circuit board has a section, referred to below as the "second" circuit board section, which carries the at least one sensor and extends beside the elongated opening formed in the cover rail. However, other components carried by the sensor circuit board—such as evaluation electronics and / or battery holders—may be located on a section of the sensor circuit board, referred to below as the "first" circuit board section, which does not extend laterally but extends in a continuation of the elongated opening formed in the cover rail.

[0019] Preferably, in this respect, the width of the second circuit board section transverse to the longitudinal extension of the cover rail may be smaller than that of the first circuit board section, thereby allowing the second circuit board section, together with the at least one sensor disposed thereon, to find space between the overlap of the window or door and the elongated opening formed in the cover rail. Since the cover rail is not typically directly adjacent to the overlap of the window or door, the second circuit board section may, in view in top view, protrude laterally beyond the cover rail in order to optimally utilize the space formed between the overlap and the elongated opening formed in the cover rail.

[0020] According to another embodiment, the sensor assembly includes a housing for accommodating a sensor circuit board, wherein the housing includes a first housing section for accommodating a first circuit board section and a second housing section for accommodating a second circuit board section. Since the first housing section accommodates the first circuit board section and the second housing section accommodates the second circuit board section, the first housing section extends in the continuation of the elongated opening formed in the cover rail, just as the first circuit board section does, while the second housing section extends to the side of the elongated opening formed in the cover rail, just as the second circuit board section does. Preferably, in this respect, the width of the second housing section transverse to the longitudinal extension of the cover rail is smaller than that of the first housing section, thereby allowing the second housing section, together with the second circuit board section therein, to be positioned between the window or door overlap and the elongated opening formed in the cover rail.

[0021] To enable the housing housing the sensor circuit board to be secured to the cover rail in two orientations with 180° relative rotation, allowing the accessory to be used for both left-hinged and right-hinged windows or doors, the housing has two opposing outer walls or surfaces parallel to the plane of the sensor circuit board housed within it. The housing is designed to be mirror-symmetrical with respect to the central plane between the two outer walls, allowing it to be secured to the cover rail in two orientations with 180° relative tilt. For example, in the case of a left-hinged window, if the second housing section is thus located to the left of the elongated opening formed in the cover rail, the housing can be rotated 180° about an axis oriented longitudinally along the cover rail to accommodate the accessory for a right-hinged door, whereby the second housing section is then located to the right of the elongated opening formed in the cover rail. In this respect, the configuration of each sensor with each closed position (rotated position, tilted position) remains unchanged, thus eliminating the need for the evaluation electronics to specifically distinguish between use with a right-hinged door and a left-hinged door.

[0022] According to another embodiment, one of the opposing outer walls of the housing may be configured as a removable housing cover, which allows access to the interior of the housing and carries a permanent magnet on its interior-facing side. Therefore, to access one or more sensors inside the housing, removing the housing cover is sufficient, without the need to specifically remove the permanent magnet, as the permanent magnet is removed along with the housing cover from the intermediate space between the two permanent magnets.

[0023] To simplify the attachment of the housing to the cover rail as much as possible, according to another embodiment, the housing can be adhered to the cover rail, particularly by means of double-sided tape. Therefore, no mechanical fastening devices are required to attach the housing to the cover rail, allowing even a layperson to attach it. Attached Figure Description

[0024] The invention will now be described by way of example only with reference to the accompanying drawings, in which:

[0025] Figure 1 An exploded perspective view of an embodiment of the accessory device according to the present invention is shown; Figure 2 It shows Figure 1 Side view of the accessory device; and Figure 3 It shows Figure 1 and Figure 2 A top view of the accessory device. Detailed Implementation

[0026] As from Figure 1 As can be seen from this, Figure 1An exemplary embodiment of the fitting device 10 according to the invention is shown in an exploded perspective view. The fitting device 10 has a cover rail 12, and a multi-part drive rod 14 is movably guided in a translational manner along the rear side of the cover rail. The drive rod 14 is located on one side of the cover rail 12 such that, in the assembled state, this side faces the fitting slot of the window or door, meaning that, in the assembled state, the drive rod 14 extends in the fitting slot in a manner known per se.

[0027] An elongated opening 18 is formed in the cover rail 12. A locking element in the form of a mushroom-head pin 16, which is fastened to the transmission rod 14, passes through the elongated opening. Thus, by manipulating the transmission rod 14, the mushroom-head pin 16 can occupy different positions in the elongated opening 18, especially the locked position, the tilted position, and the rotating position.

[0028] In order to detect these different positions of the mushroom head pin 16, a built-in sensor assembly 19 is fastened on the side of the cover rail 12 opposite to the drive rod 14. The sensor assembly has, in particular, a sensor circuit board 30 and two Hall sensors 36, 38 located thereon, by means of which the corresponding positions of the mushroom head pin 16 can be detected.

[0029] The sensor circuit board 30 is located in the housing 20, which is in turn attached to the cover rail 12 by means of double-sided tape 48.

[0030] As from Figure 1 As can be seen, the sensor circuit board 30 has a first rectangular circuit board section 32, on which are two battery holders 44 for accommodating two button batteries 46 and a plurality of electronic components. These electronic components constitute an evaluation electronics device 42 for evaluating the signals of the two Hall sensors 36, 38. The two Hall sensors are located on a second rectangular circuit board section 34, which extends in the continuation of the first circuit board section 32.

[0031] The housing 20 also has two distinct housing sections: a first housing section 22 for the first circuit board section 32 and a second housing section 24 for the second circuit board section 34. The housing 20 is arranged relative to the cover rail 12 such that, in the assembled state, the first housing section 22 extends in the continuation of the elongated opening 18 formed in the cover rail 12, while the second housing section 24 extends to the side of the elongated opening 18 formed in the cover rail 12. However, since the available space between the mushroom-head pin 16 or the elongated opening 18 and the door or window frame (in which a drive rod device is fitted in a fitting slot) is limited, the width of the second housing section 24, which accommodates the second circuit board section 34 along with the Hall sensors 36, 38 disposed therein, in its longitudinal extension transverse to the cover rail 12, is smaller than that of the first housing section 22. The same applies to the width of the second circuit board section 34, which is smaller than the width of the first circuit board section 32.

[0032] The two Hall sensors 36 and 38 are positioned in the longitudinal direction of the cover rail 12 such that one Hall sensor 36 is located near the point corresponding to the tilt position of the mushroom head pin 16, while the other Hall sensor 38 is located near the point corresponding to the locked position of the mushroom head pin 16. Thus, one Hall sensor 36 reliably outputs a signal representing the tilt position, and the other Hall sensor 38 reliably outputs a signal representing the locked position. On the other hand, the rotational position can be detected using an elimination method: if one Hall sensor 36 does not output a signal representing the tilt position, and the other Hall sensor 38 also does not output a signal representing the locked position, this conversely means that the component must be in a rotational position.

[0033] As from Figure 1 and Figure 2 As can be seen in the combined view, housing 20 has two spaced-apart planar outer walls 50, 52 that extend parallel to the plane of sensor circuit board 32 within housing 20. In the embodiment shown here, the lower outer wall 50 is adhered to the cover rail 12 by means of double-sided tape 48, thereby... Figure 1 In this configuration, the second housing section 24, along with the Hall sensors 36 and 38 located therein, is situated to the left of the elongated opening 18. In contrast, if it is desired that the fitting device 10 be used for a door or window hinged to the other side, the housing 20, along with the sensor circuit board 30 contained therein, can tilt or rotate 180° about an axis extending parallel to the cover rail 12, and in this orientation can be adhered to the cover rail 12 via double-sided tape 48, thereby... Figure 1 In the middle, the second shell section 24 is then located to the right of the elongated opening 18.

[0034] For the proper functioning of the two Hall sensors 36 and 38, a permanent magnet 40 is provided. Viewed longitudinally along the cover rail 12, the permanent magnet is positioned between the two Hall sensors 36 and 38 and is arranged inside the cover member 28, which forms part of the outer wall 52. On the other hand, another part of the outer wall 52 is constituted by a separately operable cover member 26, which, in the assembled state, covers the evaluation electronics 42 and the button battery 46.

[0035] Since the sensor assembly 19 is located on the cover rail 12, it can also be used in windows or doors where there is not enough space in the fitting slot to accommodate the corresponding sensor assembly, such as in windows or doors where the transmission rod device surrounds the entire perimeter of the window.
