[0001] FITTING ARRANGEMENT FOR LOCKING MONITORING OF

[0002] WINDOWS, DOORS OR LIFT-SLIDING ELEMENTS

[0003] 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.

[0004] Such fitting arrangements for monitoring closures are generally known, for which reference is made here purely as an example to the arrangement described in EP 3 159 464 A1.

[0005] Such fitting assemblies for locking monitoring typically have one or more contactless sensors, by means of which the various positions of the fitting assembly, which correspond to the individual positions of the associated door or window, can be monitored. In the fitting assembly described in the aforementioned EP 3 159 464 A1, for example, the locking monitoring system has three sensors, which can be used to check whether the fitting assembly is in a locking position, a pivot-open position, or a tilt-open position.In the fitting assembly described in EP 3 159 464 A1, the sensors for locking monitoring are located on the faceplate and thus in the rebate gap of a window or door. This means that this fitting assembly can only be used with a sufficiently large rebate gap or if the rebate gap has been appropriately reworked for locking monitoring. The invention is therefore based on the object of specifying a fitting assembly for locking monitoring that can also be used with windows, doors, or lift-and-slide elements with only a relatively small rebate gap.

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

[0007] 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. The drive rod has a first section that rests against a surface of the faceplate facing the fitting groove and is thus concealed by the faceplate when the fitting assembly is installed in a window or door. Furthermore, the drive rod has a second distance that projects beyond one end of the faceplate in continuation of the faceplate and is thus, unlike the first drive rod section, not concealed by the faceplate.

[0008] According to the invention, the fitting assembly comprises a sensor board coupled at least indirectly to the faceplate, which has at least one contactless sensor for detecting the position of the drive rod. Preferably, several contactless sensors are located on the sensor board in order to be able to detect different positions of the drive rod, such as the previously mentioned positions – locking position, open-turn position, and tilt-open position. The sensor board is located at the aforementioned end of the faceplate and extends in continuation of the same, so that the sensor board flanks or covers the second section of the drive rod.

[0009] In order to ensure that the sensor(s) provided on the sensor board do not extend into the rebate air gap of a window or 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 are located in the mounted state of the fitting arrangement.

[0010] The sensor board or the at least one sensor provided thereon therefore does not take up any space in the rebate air gap of a window or door, so that the fitting arrangement according to the invention can also be used for windows or doors with only a small rebate air gap.

[0011] Since common 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 that the sensor board can utilize a section of a fitting groove that is not occupied by the faceplate or the connecting rod guided thereon. The fitting arrangement according to the invention thus optimally utilizes the already available space within a fitting groove of a window or door, eliminating the need to create additional space to accommodate the sensor board.

[0012] Furthermore, the fitting arrangement according to the invention proves to be advantageous in that, due to the fact that the sensor board is attached at least indirectly to the faceplate as a prefabricated assembly, the relative position between the sensor board or the at least one sensor and the drive rod is predetermined, so that the individual switching positions do not have to be taught individually. Further embodiments of the fitting arrangement according to the invention will now be discussed below, whereby further embodiments may also arise from the dependent claims, the description of the figures, and the figures themselves.

[0013] Thus, according to one embodiment, the at least one sensor can be a magnetic field sensor, such as a Hall sensor, to which a magnet is assigned as a detection means, which magnet 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 is already present in the drive rod and typically serves to connect another drive rod or an assembly to be actuated by the fitting arrangement.

[0014] According to a further embodiment, the sensor board may have a battery holder on the side where the at least one sensor is located, for accommodating a battery for supplying power to the at least one sensor. A battery accommodated by the battery holder thus 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 door.

[0015] Preferably, it can be provided that the second section of the drive rod has a free end over which that section of the sensor board on which the battery holder is located projects. Because the section of the sensor board on which the battery holder is located projects over the free end of the drive rod, and the battery holder is located on that side of the sensor board on which the at least one sensor is also located, the battery holder extends into the fitting groove of a window or door when the fitting arrangement is installed. Due to the installation space that conventional windows or doors provide within their fitting groove, commercially available batteries and / or rechargeable batteries of type AA or AAA can be used, which, unlike button cells, ensure a long-term power supply to power the at least one sensor.

[0016] According to yet another embodiment, the fitting assembly may include a mounting frame that is at least indirectly coupled to the faceplate, which accommodates the sensor board and extends at the end of the faceplate as a continuation of the same. The mounting frame is thus a type of adapter by means of which the sensor board can be attached to conventional fitting assemblies.

[0017] Preferably, the mounting frame can be provided with a receiving seat on the side opposite the drive rod for precisely accommodating the sensor board. The sensor board can thus be removed from the mounting frame while the fitting assembly is mounted in a fitting groove, for example, to replace a dead battery with a new one. Replacing the battery eliminates the need to first remove the mounting frame from the faceplate, as the sensor board is accessible while the fitting assembly is mounted in a fitting groove.

[0018] While the sensor board can be secured within the mounting frame's receiving seat, for example, using a locking mechanism, the sensor board can also be secured in the mounting frame by a cover that conceals the receiving seat and is removably attached to the mounting frame. The cover thus acts as a type of closure lid that not only protects the sensor board from external environmental influences but also reliably secures it within the mounting frame.

[0019] In the following, the invention will now be explained purely by way of example with reference to the figures, in which:

[0020] Fig. 1 shows a perspective exploded view of an embodiment of a fitting arrangement according to the invention;

[0021] Fig. 2 shows the fitting arrangement of Fig. 1 in a side view; and

[0022] Fig. 3 shows the fitting arrangement of Figs. 1 and 2 in a plan view.

[0023] As can be seen from Fig. 1, which shows an exemplary embodiment of a fitting arrangement 10 according to the invention as a perspective exploded view, the fitting arrangement 10 has a faceplate 12, which in this case runs around a corner and along which a drive rod 14 is guided so as to be translationally displaceable. Although the faceplate 12 is designed as a corner bracket here and accordingly the drive rod 14 is coupled via a corner deflection element 16 to a vertically oriented drive rod (not shown here), the faceplate 12 can also be just a straight, elongated rail for covering, for example, a horizontally or vertically oriented fitting groove of a window, a door or a lift-slide element. As already mentioned, the drive rod 14 is guided so as to be translationally displaceable along the faceplate 12.For this purpose, a guide adapter 20 is fastened to a free end 18 of the faceplate 12 by means of a rivet 22, wherein this guide adapter 20 slidably accommodates the drive rod 14 in its interior so that the drive rod can be moved along the faceplate 12 guided by the guide adapter 20. 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 in the fitting groove in a manner known per se when mounted.

[0024] As can further be seen from Fig. 1, the drive rod 14 has a first section 24, which is concealed by the faceplate 12, and a second section 26, which projects beyond the free end of the faceplate 12 and is thus not concealed by the same. Even if this is of minor importance for the present invention, the second section 26 of the drive rod 14 has a toothed coupling shoe 28 at its free end, which serves, if necessary, for coupling to subsequent drive rods. However, such a coupling of further drive rods is not provided for according to the invention, as will become apparent from the following explanations of the fitting arrangement 10 according to the invention.

[0025] As can also be seen from Fig. 1, the guide adapter 20 is penetrated by a hole 30, which is usually used to attach additional faceplates. Instead of attaching another faceplate to the faceplate 12 via the guide adapter 20 or the hole 30 formed thereon, an elongated mounting frame 32 is coupled to the faceplate 12 by means of the guide adapter 20. The elongated mounting frame 32 has the same width as the faceplate 12 and extends along the fitting groove. The mounting frame 32 thus conceals the second drive rod section 26. The mounting frame 32 in turn serves to accommodate a strip-like sensor board 34, which can be inserted into the mounting frame 32 from above or from the front on the side opposite the drive rod 14.To accommodate the sensor board 34, the mounting frame 32 forms in its interior a receiving seat 36 which is essentially complementary to the outer contour of the sensor board 34, so that the sensor board 34 is held in its plane in the mounting frame 32 without play.

[0026] To prevent the sensor board 34 from falling out of the mounting frame 32, a cover 38 can be removably attached to the mounting frame 32, which, when attached to the mounting frame 32, covers the receiving seat 32. The sensor board 34 is thus held in place in the receiving seat 36 between the mounting frame 32 and the cover 38.

[0027] The sensor board 34 is thus indirectly attached to the faceplate 12 via the mounting frame 32 and the guide adapter 20 and extends in continuation of the same.

[0028] The sensor board 34 serves to detect individual switching positions of the drive rod 12, such as a closed position, a rotary opening position, and a tilt opening position. For this purpose, the sensor board 34 has a contactless sensor 40 on its side facing the drive rod 14 for each switching position to be detected. These sensors can be, for example, Hall sensors. Since the sensors 40 are located on the back of the sensor board or on the side of the sensor board 14 facing the drive rod 14, they are only indicated schematically here.

[0029] Although the individual switching positions of the drive rod 14 can be detected by the sensors 40 in question based on the change in the earth's magnetic field resulting from a displacement of the drive rod 14, the detection accuracy of the sensors 40 is more precise if they are assigned a magnet as a detection means. Accordingly, the drive rod 14 accommodates a magnet 44 as a detection means in a hole 42 formed in its second section 26. Specifically, the magnet 44 is accommodated by an adapter sleeve 46, which in turn is fitted into the hole 42 of the second drive rod section 46.

[0030] Although the sensor plate 34, and in particular the at least one sensor 40 provided thereon, can be supplied with power via an external energy source, the invention provides that a battery holder 48 in the form of two terminal contacts is provided on the sensor board 34 itself, of which only one is visible in Fig. 1. Like the sensors 40, the battery holder 48 is also located on the side of the sensor board 34 facing the drive rod 14, specifically on a section of the sensor board 34 that projects beyond the free end of the second drive rod section 26.

[0031] A battery 50, accommodated in the battery holder 48 for powering the sensor board 34, thus extends in a plane defined by the drive rod 14. When the fitting assembly 10 according to the invention is mounted on a window or door, the battery 50, like the drive rod 14, is located in the fitting groove of the window or door. High-performance AA or AAA batteries 50 can thus be used to power the sensor board 34, ensuring a long-term power supply to the sensor board 34 without the need for premature replacement of the battery 50.

[0032] As can further be seen from Figures 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 door.

[0033] To ensure a secure hold of the fitting assembly 10 according to the invention in the fitting groove of a window or door, an opening 54 is formed at the free end of the mounting frame 32, which in the embodiment shown here also extends through the battery housing 52. The opening 54 serves to accommodate a screw (not shown) by means of which the fitting assembly 10 can be screwed into the fitting groove of a window or door.
