Description

[0001] FITTING ARRANGEMENT FOR LOCKING MONITORING OF WINDOWS, DOORS OR LIFT-SLIDING ELEMENTS

[0002] The present invention relates to a fitting arrangement for monitoring the closure of windows, doors or lift-slide elements, such as lift-slide doors or lift-slide windows.

[0003] Such fitting arrangements for monitoring closures are generally known, and at this point reference is made purely as an example to the fitting arrangement described in the German patent application with the official file number 10 2023 133 589.8.

[0004] Fitting arrangements of this type for monitoring locking typically feature one or more contactless sensors, which can be used to monitor different positions of the drive rod, which correspond to the individual positions of the associated door or window. These positions are generally the tilt position, the turn position, and the locking position. In the fitting arrangement described in the aforementioned German patent application, the sensors, or rather the sensor board carrying the sensors, and in particular the battery for powering the sensors, are located in the fitting groove of the associated door or window. This fitting arrangement is therefore only suitable for windows or doors where the drive rod arrangement does not extend around the entire circumference of the window or door.In other words, the fitting arrangement described in the aforementioned German patent application requires that the faceplate has a free end, in continuation of which the sensor board can extend in the fitting groove.

[0005] The invention is therefore based on the object of specifying a fitting arrangement for locking monitoring, which can also be used for windows, doors or lift-slide elements in which the fitting groove cannot be used to accommodate sensors for locking monitoring.

[0006] This object is achieved by a fitting arrangement for windows, doors and lift-slide elements, which is characterized by the features of claim 1.

[0007] Specifically, the fitting assembly according to the invention comprises a faceplate, by means of which a fitting groove formed in a door or window can be covered, and a drive rod guided so as to be translationally displaceable along the faceplate. At least one locking element, such as a locking pin, in particular a mushroom-head or roller pin, is attached to the drive rod. The locking element extends through an elongated hole formed in the faceplate and can be displaced in the longitudinal direction thereof by actuating the drive rod.

[0008] According to the invention, a sensor assembly is mounted on the side of the faceplate opposite the drive rod. This sensor assembly has at least one contactless sensor, in particular at least one Hall sensor, for detecting the position of the locking element—locking position, tilt position, rotation position. Viewed from the faceplate, the at least one contactless sensor is located to the side of the elongated hole formed in the faceplate.

[0009] According to the invention, the at least one sensor is therefore not located in continuation of the faceplate or in continuation of the elongated hole opening; rather, the invention provides that the at least one contactless sensor is located in the region of the elongated hole opening, viewed in the longitudinal direction of the faceplate, to the side of it. When the fitting arrangement is 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 hole opening formed in the faceplate, so that when the window or door is closed, the sensor does not collide with the strike plate on the frame that is assigned to the locking element movable in the elongated hole opening.

[0010] The at least one sensor is located directly laterally adjacent to the movement area of ​​the locking element, where sufficient space must be available for the locking element in the rebate gap anyway. The fitting arrangement according to the invention thus optimally utilizes the space already available in the rebate gap. The fitting arrangement can therefore also be used when the rebate gap is already occupied by other components or offers relatively little space for any retrofit components.

[0011] In particular, however, the fitting arrangement according to the invention proves to be advantageous in that its sensor does not take up any installation space in the fitting groove, so that the fitting arrangement can also be used with windows or doors in which the drive rod arrangement runs around the entire circumference of the window or door. A further advantage is that the signal provided by the at least one sensor leaves little doubt as to the respective drive rod position, since the respective signal is directly influenced by the locking element. In other words, the influence of the locking element on the magnetic field monitored by the at least one sensor is relatively large, which means that the monitoring signal emitted by the at least one sensor changes relatively strongly depending on the respective drive rod position.This means that the respective drive rod position - locking position, tilt position, rotation position - can be detected very reliably.

[0012] In the following, further embodiments of the fitting arrangement according to the invention will be discussed, wherein further embodiments can also arise from the dependent claims, the description of the figures and the figures themselves.

[0013] Thus, according to a first embodiment, the fitting assembly can comprise precisely two contactless sensors, both of which are located, as previously described, to the side of the slotted hole formed in the faceplate. The two sensors can be spaced apart from each other in the longitudinal direction of the slotted hole, namely by an amount by which the locking element moves between the rotational position and the tilted position.

[0014] Preferably, it can be provided that one of the two sensors is located close to a point at which the locking element is in the tilted position, whereas the other of the two sensors is located close to a point at which the locking element is in its locked position. One sensor therefore very reliably outputs a signal that is representative of the tilted position, whereas the other sensor very reliably outputs a signal that is representative of the locked position. The rotated position, on the other hand, can be detected by a process of elimination: if neither one sensor outputs a signal representative of the tilted position, nor the other sensor outputs a signal representative of the locked position, it can be determined by a process of elimination that the fitting must necessarily be in the rotated position.

[0015] It would indeed be possible to integrate a permanent magnet into the locking element so that the sensor(s) could detect the change in the magnetic field of the permanent magnet in question and thus the respective locking position. However, since the locking elements of conventional espagnolette arrangements can only be retrofitted with such permanent magnets with a certain amount of effort, a further embodiment can provide for a permanent magnet, in particular a single permanent magnet, to be assigned to the at least one sensor, which, when viewed along the faceplate, is also located to the side of the elongated hole formed in the faceplate. The at least one sensor is thus pre-tensioned by the permanent magnet assigned to it, so that the sensor(s) can detect a change in the magnetic field of the permanent magnet in question and thus the respective locking position.The sensors can detect the change in the magnetic field generated by the permanent magnet, which is generated by the locking element assuming different positions in the magnetic field depending on the position of the fitting assembly. The at least one sensor thus detects the change in the magnetic field caused by the locking element, so that the respective change in the magnetic field can be assigned to one of the switching positions in question.

[0016] As already mentioned above, it may be sufficient to assign only a single permanent magnet to both sensors; in this case, according to a further embodiment, it may prove advantageous to place this single permanent magnet between the two sensors, viewed in the longitudinal direction of the faceplate, so that both sensors are prestressed by the permanent magnet with substantially the same strength.

[0017] According to a further embodiment, it can be provided that the sensor assembly comprises a sensor board which carries the at least one sensor, evaluation electronics for the at least one sensor and / or at least one battery holder for receiving a battery for supplying power to the at least one sensor and the evaluation electronics.

[0018] Since it is essential for reliable detection of the individual positions of the locking element that the at least one sensor is located laterally of the elongated hole formed in the faceplate, the sensor board has a section, hereinafter referred to as the "second" board section, which carries the at least one sensor and extends laterally of the elongated hole formed in the faceplate. The other components carried by the sensor board, such as the evaluation electronics and / or the battery holder, can, however, be located on a section of the sensor board, hereinafter referred to as the "first" board section, which does not extend laterally but rather as a continuation of the elongated hole formed in the faceplate.

[0019] Preferably, the second plate section can be provided with a smaller width than the first plate section transversely to the longitudinal extent of the faceplate, so that the second plate section with the at least one sensor provided thereon can be accommodated between the overlap of the window or door and the elongated hole formed in the faceplate. Since the faceplate often does not directly adjoin the overlap of the window or door, the second plate section can project laterally beyond the faceplate when viewed from the front, in order to optimally utilize the space formed between the overlap and the elongated hole formed in the faceplate.

[0020] According to yet another embodiment, it can be provided that the sensor group comprises a housing for receiving the sensor circuit board, wherein the housing comprises a first housing section for receiving the first circuit board section and a second housing section for receiving the second circuit board section. Since the first housing section receives the first circuit board section and the second housing section receives the second circuit board section, the first housing section, like the first circuit board section, extends in continuation of the elongated hole opening formed in the faceplate, whereas the second housing section, like the second circuit board section, extends laterally of the elongated hole opening formed in the faceplate.It is preferably provided that the second housing section has a smaller width transversely to the longitudinal extent of the faceplate than the first housing section, so that the second housing section with the second plate section located therein can be placed between the window or door overlap and the elongated hole opening formed in the faceplate.

[0021] To enable the housing housing the sensor board to be attached to the faceplate in two orientations tilted 180° to each other, so that the fitting arrangement can be used for both left- and right-hinged windows or doors, the housing has two opposing outer walls or outer surfaces that are plane-parallel to the sensor board housed in the housing. The housing is mirror-symmetrical with respect to a center plane between the two outer walls, allowing it to be attached to the faceplate in two orientations tilted 180° to each other.For example, if the second housing section of a left-hinged window is located to the left of the elongated hole in the faceplate, the housing can be tilted 180° around an axis aligned longitudinally with the faceplate to insert the hardware assembly into a right-hinged door, so that the second housing section is then located to the right of the elongated hole in the faceplate. The assignment of the individual sensors to the individual locking positions (turn position, tilt position) remains the same, so the evaluation electronics do not have to specifically distinguish between the use of the hardware assembly on a right-hinged or left-hinged door.

[0022] According to yet another embodiment, one of the opposing outer walls of the housing can be designed as a removable housing cover, which provides access to the interior of the housing and carries the permanent magnet on its side facing the interior of the housing. Thus, to gain access to the sensor(s) inside the housing, it is sufficient to remove the housing cover without having to remove the permanent magnet, since the permanent magnet is removed from the space between the two permanent magnets along with the housing cover.

[0023] To make attaching the housing to the faceplate as easy as possible, a further embodiment provides for the housing to be glued to the faceplate, particularly using double-sided adhesive tape. This eliminates the need for any mechanical fastening devices to attach the housing to the faceplate, allowing it to be attached to the faceplate even by non-professionals.

[0024] In the following, the invention will now be explained purely by way of example with reference to the figures, in which: Fig. 1 shows a perspective exploded view of an embodiment of a fitting arrangement according to the invention;

[0025] Fig. 2 shows the fitting arrangement of Fig. 1 in a side view; and

[0026] Fig. 3 shows the fitting arrangement of Figs. 1 and 2 in a plan view.

[0027] As can be seen from Fig. 1, which shows an exemplary embodiment of a fitting assembly 10 according to the invention as a perspective exploded view, the fitting assembly 10 has a faceplate 12, along the rear of which a multi-part drive rod 14 is guided for translational displacement. The drive rod 14 is located on that side of the faceplate 12 which, when mounted on a window or door, faces the fitting groove of the window or door, which means that the drive rod 14 extends into the fitting groove in a manner known per se when mounted.

[0028] In the faceplate 12, an elongated hole opening 18 is formed, through which a locking element in the form of a mushroom-head pin 16 fastened to the drive rod 14 extends, so that the mushroom-head pin 16 can assume different positions in the elongated hole opening 18 as a result of actuation of the drive rod 14, in particular a locking position, a tilting position and a rotating position.

[0029] In order to be able to detect these different positions of the mushroom head pin 16, a sensor assembly 19 is fastened to the faceplate 12 on the side opposite the drive rod 14, which sensor assembly comprises in particular a sensor board 30 with two Hall sensors 36, 38 located thereon, by means of which the respective positions of the mushroom head pin 16 can be detected.

[0030] The sensor board 30 is located in a housing 20, which in turn is glued to the faceplate 12 by means of a double-sided adhesive tape 48.

[0031] As can be seen from Fig. 1, the sensor board 30 has a first rectangular board section 32, on which are located two battery holders 44 for accommodating two button cells 46, as well as several electronic components forming an evaluation electronics 42 for evaluating the signals from the two Hall sensors 36, 38. These, in turn, are located on a second rectangular board section 34, which extends as a continuation of the first board section 32.

[0032] The housing 20 also has two different housing sections, namely 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 with respect to the faceplate 12 in such a way that the first housing section 22, in the assembled state, extends in continuation of the elongated hole opening 18 formed in the faceplate 12, whereas the second housing section 24 extends laterally of the elongated hole opening 18 formed in the faceplate 12. However, since the available space between the mushroom head pin 16 or the elongated hole opening 18 and the overlap of the door orWindow frame, in whose fitting groove the drive rod assembly is mounted, the second housing section 24, which accommodates the second plate section 34 with the Hall sensors 36, 38 provided thereon, has a smaller width transversely to the longitudinal extent of the faceplate 12 than the first housing section 22. The same applies to the width of the second plate section 34, which is smaller than the width of the first plate section 32.

[0033] The two Hall sensors 36, 38 are positioned in the longitudinal direction of the faceplate 12 such that one Hall sensor 36 is located in the longitudinal direction of the faceplate close to the point corresponding to the tilted position of the mushroom-head pin 16, whereas the other Hall sensor 38 is located close to a point corresponding to the locked position of the mushroom-head pin 16. Thus, one Hall sensor 36 very reliably outputs a signal representative of the tilted position, whereas the other Hall sensor 38 very reliably outputs a signal representative of the locked position. The rotational position, however, can be detected by a process of elimination: If neither one Hall sensor 36 outputs a signal representative of the tilted position, nor the other Hall sensor 38 outputs a signal representative of the locked position, this means, conversely, that the fitting must necessarily be in the rotational position.

[0034] As can be seen from the combined view of Figs. 1 and 2, the housing 20 has two spaced-apart, flat outer walls 50, 52, which run plane-parallel to the sensor board 32 in the housing 20. In the embodiment shown here, the lower outer wall 50 is glued to the faceplate 12 using the double-sided adhesive tape 48, so that in Fig. 1, the second housing section 24 with the Hall sensors 36, 38 located therein is located to the left of the elongated hole opening 18. If, in contrast, it is desired to use the fitting arrangement 10 on a door or window that is hinged on the other side, the housing 20, including the sensor board 30 contained therein, can be tilted or rotated by 180° about an axis running parallel to the faceplate 12 and, in this orientation, can be glued to the faceplate 12 using the double-sided adhesive tape 48 in such a way that, in Fig.1 the second housing section 24 is then located to the right of the elongated hole opening 18.

[0035] For the proper functioning of the two Hall sensors 36, 38, a permanent magnet 40 is assigned to them, which is located in the longitudinal direction of the

[0036] Viewed from the faceplate 12, it is located between the two Hall sensors 36, 38 and is arranged on the inside of a cover part 28, which forms part of the outer wall 52. The other part of the outer wall 52, however, is formed by a separately handleable cover part 26, which, when mounted, covers the evaluation electronics 42 and the button cells 46.

[0037] Since the sensor assembly 19 is located on the faceplate rail 12, it can also be used for windows or doors where there is not enough space in the fitting groove to accommodate a corresponding sensor assembly, as is the case, for example, with windows or doors where the drive rod arrangement surrounds the entire circumference of the window.
