Description

The present invention relates to a fitting arrangement for monitoring the closure of windows, doors or lifting sliding elements, such as lifting sliding doors or lifting sliding windows.Such fitting arrangements for closure monitoring are known in principle, for which purpose reference is made at this point purely by way of example to the arrangement described in EP 3 159 464 A1.Such fitting arrangements for closure monitoring usually have one or more non-contact sensors, by means of which the different positions of the fitting arrangement, which in this respect correspond to the individual positions of the assigned door or the assigned window, can be monitored. In the fitting arrangement described in the aforementioned EP 3 159 464 A1, for example, the closure monitoring system has three sensors, by means of which it can be checked whether the fitting arrangement is in a closure position, in a rotational open position or in a tilting open position. In the fitting arrangement described in EP 3 159 464 A1, the sensors for the closure monitoring are located on the apron rail and thus in the folding air of a window or a door, so that this fitting arrangement can only be used in the case of sufficiently large-dimensioned folding air or then when the folding air for the closure monitoring has been correspondingly processed.The invention is therefore based on the object of specifying a fitting arrangement for closure monitoring which can also be used in the case of windows, doors or lifting slide elements with folding air of only relatively small dimensions.This object is achieved with a fitting arrangement for windows or doors and for lifting slide elements, which is distinguished by the features of claim 1.The fitting arrangement according to the invention has a lock rail, by means of which a fitting groove formed in a door or in a window can be covered, and a drive rod which is guided in a translatory displaceable manner along the lock rail. The drive rod has a first section which abuts a surface of the cuff rail facing the fitting groove and is therefore concealed by the cuff rail when the fitting arrangement is installed in a window or a door. In addition, the drive rod has a second distance which projects beyond an end of the cuff rail in continuation thereof and which is therefore not covered by the cuff rail, unlike the first drive rod section.According to the invention, the fitting arrangement has a sensor printed circuit board which is coupled at least indirectly to the cuff rail and on which at least one sensor which operates in contactless fashion for detecting the position of the drive rod is provided. Preferably, a plurality of non-contact sensors are located on the sensor circuit board in order to be able to detect different positions of the drive rod such as, for example, the positions already mentioned above-closure position, rotational opening position and tilting opening position. The sensor board is located at the end of the cuff rail already mentioned and extends as a continuation thereof, so that the sensor board inflates or covers the second section of the drive rod.In order that the sensor or sensors provided on the sensor board do not extend into the folding air of a window or a door, the at least one sensor is located according to the invention on that side of the sensor board which faces the second section of the drive rod and thus the fitting groove in which the drive rod and thus also the at least one sensor is located in the assembled state of the fitting arrangement.The sensor printed circuit board or the at least one sensor provided thereon thus does not take up any space in the folding air of a window or a door, so that the fitting arrangement according to the invention can also be used in windows or doors with only a small folding air.Since conventional fitting arrangements often do not occupy the entire length of a fitting groove, a further advantage of the fitting arrangement according to the invention is furthermore that the sensor printed circuit board can use a section of a fitting groove which is not occupied by the lug rail or the drive rod guided thereon. The fitting arrangement according to the invention thus optimally uses the region already available within a fitting groove of a window or a door, so that no additional installation space has to be created for accommodating the sensor circuit board.In addition, the fitting arrangement according to the invention has proven advantageous in that, due to the fact that the sensor board is fastened at least indirectly to the cuff rail as a prefabricated module, the relative position between the sensor board or the at least one sensor and the drive rod is fixed in advance, so that the individual switching positions do not have to be taught individually.In the following, further embodiments of the fitting arrangement according to the invention will now be discussed, wherein further embodiments can also be derived from the dependent claims, the description of the figures and the figures themselves.Thus, according to one embodiment, it can be provided that the at least one sensor is a magnetic field sensor, such as a Hall sensor, for example, to which a magnet is assigned as detection means, which is located on the second section of the drive rod. In particular, the magnet can be located in a hole at the end of the second drive rod section, which hole is already present in the drive rod from the home and usually serves for coupling a further drive rod or a subassembly, which is to be actuated by means of the fitting arrangement.According to a further embodiment, it can be provided that the sensor board has, on that side on which the at least one sensor is located, a battery holder for receiving a battery for supplying power to the at least one sensor. A battery accommodated by the battery holder therefore extends at least partially in a plane defined by the drive rod, so that the battery, like the drive rod, is accommodated by the fitting groove of a window or a door.Preferably, it can be provided that the second section of the drive rod has a free end, over which the section of the sensor circuit board, on which the battery holder is located, protrudes. Due to the fact that the section of the sensor circuit board on which the battery holder is located protrudes beyond the free end of the drive rod and the battery holder is located on that side of the sensor circuit board on which the at least one sensor is also located, the battery holder thus extends into the fitting groove of a window or a door in the assembled state of the fitting arrangement. Due to the installation space available for conventional windows or doors within their fitting groove, commercially available batteries and / or rechargeable batteries of the type AA or AAA can thus be used, which, unlike button cells, ensure a long-year energy supply for energizing the at least one sensor.According to yet another embodiment, it can be provided that the fitting arrangement has a mounting frame which is coupled at least indirectly to the cuff rail and which accommodates the sensor circuit board and which extends at the end of the cuff rail in continuation thereof. The mounting frame is thus a type of adapter, by means of which the sensor circuit board can be attached to fitting arrangements which are conventional per se.Preferably, it can be provided here that the mounting frame forms a receiving seat on the side opposite the drive rod for precisely fitting receiving of the sensor circuit board. The sensor circuit board can thus be removed from the mounting frame in the state of the fitting arrangement mounted in a fitting groove, in order to be able to replace a depleted battery with a new one, for example. For replacing the battery, it is therefore not necessary to first remove the mounting frame from the mounting rail, since the sensor circuit board is accessible in the state of the fitting arrangement mounted in a fitting groove.The sensor board can be secured within the receiving seat of the mounting frame, for example, by means of a latching mechanism. In addition, however, the sensor board may be secured in the mounting frame by a cover covering the receiving seat and detachably attached to the mounting frame. The cover is thus a type of closure cover, by means of which the sensor circuit board is not only protected from external environmental influences, but is also reliably secured in the mounting frame.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; FIG. 2 shows the fitting arrangement of FIG. 1 in a side view; and FIG. 3 shows the fitting arrangement of FIGS. 1 and 2 in a plan view.As can be seen from FIG. 1, which shows an exemplary embodiment of a fitting arrangement 10 according to the invention as an exploded perspective view, the fitting arrangement 10 has a cuff rail 12 which is guided here over corners and along which a drive rod 14 is guided in a translatory displaceable manner. Although the cuff rail 12 is designed here as a corner angle and accordingly the drive rod 14 is coupled via a corner deflection member 16 to a vertically oriented drive rod, not shown here, the cuff rail 12 can also only be a straight elongate rail for covering, for example, a horizontally or vertically oriented fitting groove of a window, a door or a lifting slide element.As already mentioned, the drive rod 14 is guided in a translatory displaceable manner along the cuff rail 12. For this purpose, a guide adapter 20 is fastened to a free end 18 of the cuff rail 12 by means of a rivet 22, wherein said guide adapter 20 receives the drive rod 14 in a displaceable manner in its interior, so that said drive rod can be displaced along the cuff rail 12 guided by the guide adapter 20. The drive rod 14 is located on that side of the apron rail 12 which, in the state in which it is mounted on a window or a door, faces the fitting groove of the window or the door, which means that the drive rod 14, in the mounted state, extends in a manner known per se in the fitting groove.As can also be seen from FIG. 1, the drive rod 14 has a first section 24 which is concealed by the cuff rail 12 and a second section 26 which projects beyond the free end of the cuff rail 12 and is therefore not concealed by the latter. Although this is of more secondary importance to the present invention, the second section 26 of the drive rod 14 has at its free end a toothed coupling shoe 28 which, if required, serves for coupling to subsequent drive rods. However, such a coupling of further drive rods is not provided according to the invention, as will be apparent from the following explanations of the fitting arrangement 10 according to the invention.As can also be seen from FIG. 1, the guide adapter 20 is traversed by a hole 30, which usually serves for the attachment of further cuff rails. Instead of fastening a further cuff rail to the cuff rail 12 via the guide adapter 20 or the hole 30 formed thereon, an elongate mounting frame 32 is coupled to the cuff rail 12 by means of the guide adapter 20, which elongate mounting frame has the same width dimension as the cuff rail 12 and extends along the fitting groove. The mounting frame 32 thus in turn covers the second drive rod section 26.The mounting frame 32 in turn serves to receive a sensor circuit board 34 which is of strip-like design and which can be inserted into the mounting frame 32 from above or from the front from the side opposite the drive rod 14. For receiving the sensor circuit board 34, the mounting frame 32 forms in its interior a receiving seat 36 which is substantially complementary to the outer contour of the sensor circuit board 34, so that the sensor circuit board 34 is held in the mounting frame 32 without play in its plane.In order that the sensor board 34 cannot fall out of the mounting frame 32, a cover 38 can be releasably attached to the mounting frame 32, which cover covers the receiving seat 32 in the state attached to the mounting frame 32. The sensor board 34 is thus held in place between the mounting frame 32 and the cover 38 in the receiving seat 36.The sensor circuit board 34 is thus fastened indirectly via the mounting frame 32 and the guide adapter 20 to the cuff rail 12 and extends in continuation thereof.The sensor circuit board 34 serves here for detecting individual switching positions of the drive rod 12, such as a closed position, a rotational open position and a tilting open position. For this purpose, the sensor circuit board 34 has, on its side facing the drive rod 14, a non-contact sensor 40 for each switching position to be detected, which sensor can be, for example, a Hall sensor in each case. Since the sensors 40 are located on the rear side of the sensor circuit board or on the side of the sensor circuit board 14 facing the drive rod 14, these are only schematically indicated here.Although the individual switching positions of the drive rod 14 can be detected by means of the sensors 40 in question by the change of the earth's magnetic field as a result of a displacement of the drive rod 14, the detection accuracy of the sensors 40 is more accurate if a magnet is assigned to them as detection means. Accordingly, the drive rod 14 receives a magnet 44 as a detecting means in a hole 42 formed in its second portion 26. Specifically, the magnet 44 is received by an adapter sleeve 46, which in turn is fitted into the hole 42 of the second drive rod section 46.Although the sensor plate 34 and in particular the at least one sensor 40 provided thereon can be supplied with current via an external energy source, it is provided according to the invention that a battery holder 48 in the form of two clamping contacts is provided on the sensor circuit board 34 itself, of which only one can be seen in FIG. 1. Like the sensors 40, the battery holder 48 is also located on the side of the sensor printed circuit board 34 facing the drive rod 14, namely on a section of the sensor printed circuit board 34 which projects beyond the free end of the second drive rod section 26.A battery 50 received by the battery holder 48 for energizing the sensor circuit board 34 thus extends in a plane defined by the drive rod 14. In the state of the fitting arrangement 10 according to the invention mounted on a window or a door, the battery 50 is thus located in the fitting groove of the window or of the door, like the drive rod 14. High-performance batteries 50 of the AA or AAA type can thus be used to supply power to the sensor circuit board 34, as a result of which a long-year power supply to the sensor circuit board 34 can be ensured without the battery 50 having to be replaced at an early stage.As can also be gathered from FIGS. 1 and 2, a battery housing 52 for receiving the battery 50 is formed on the side of the mounting frame 32 facing the drive rod 14 or on the side of the mounting frame 32 facing the fitting groove of a window or a door.In order to ensure a secure hold of the fitting arrangement 10 according to the invention in the fitting groove of a window or a door, an opening 54 is formed at the free end of the mounting frame 32, which opening also passes through the battery housing 52 in the embodiment shown here. The opening 54 serves to receive a screw (not shown), by means of which the fitting arrangement 10 can be screwed into the fitting groove of a window or a door.List of reference characters10 Fitting arrangement 12 Cuff rail 14 Drive rod 16 Corner deflection member 18 Free end of the cuff rail 20 Guide adapter 22 Rivet 24 First drive rod section 26 Second drive rod section 28 Coupling shoe 30 Hole in 20 32 Mounting frame 34 Sensor printed circuit board 36 Receiving seat 38 Cover 40 Sensor 42 Hole 44 Magnet 46 Adapter sleeve 48 Battery holder 50 Battery 52 Battery housing 54 OpeningReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
