DETAILED DESCRIPTION

[0024] FIG. 1 shows a schematic representation of a charging layout 1 as described herein, serving to charge an energy accumulator of a motor vehicle. This comprises a charging device 2, here, a wallbox, which is located on a building wall 3, shown here as transparent for purposes of the drawing. A cable 4 runs to the charging device 2, coming from the interior of a cellar 5 of a building, only suggested, and being led to the outside. An electrical distribution or circuit box 7 is arranged on a masonry 6, in which a household conduit 8 runs, being supplied from the outside. The cable 4 runs from the circuit box 7 to a window 9, through the frame of which it is led. For this, multiple cable bushings are provided on the frame, as will be further explained below. On the outside, the window 9 is adjoined by a light shaft 10, through which the cable 4 in the example shown runs directly to the charging device 2. The cable 4 is a power cable, which is designed for a voltage of 380 V, for example.

[0025] FIG. 2 shows in an enlarged view the masonry 6 plus the circuit box 7 and the window 9. The window 9, for which also see FIG. 3, comprises a frame 11, which in the example shown is designed to be installed or anchored directly in a soffit 12, which bounds a window opening 13 in the masonry 6. In the frame 11 there is swivel-mounted in known manner a pivot frame 14 having a window pane 15 by means of corresponding hinge elements 16. The window can be locked in the locked position or unlocked and opened through a window handle 17 with associated locking element.

[0026] The frame 11 has a somewhat broadened frame leg 18, shown at the right in the example, on which multiple cable bushings, in the example four separate cable bushings 19a, 19b, 19c, 19d, are provided. These cable bushings 19a, 19b, 19c, 19d are configured here as circular round boreholes, all of them having the same cross sectional shape, but differing in the cross sectional area. Thus, the cable bushing 19a has the largest diameter, which decreases in steps to the smallest diameter of the cable bushing 19d. Consequently, a cable 4 being led out from the building, and naturally also having a corresponding cross sectional area, can be led through the cable bushing 19a-d whose cross sectional area best corresponds to its cross sectional area.

[0027] This situation is shown in FIG. 2. Here, the cable 4 is led from the inside to the outside through the second largest cable bushing 19b, the cable bushings 19a-19d naturally running from the inner frame side to the outer frame side, so that the cable 4 can emerge on the outside of the masonry and run to the charging device 2.

[0028] In the configuration of FIG. 2, the unoccupied cable bushings 19a, 19c, 19d are shown opened. After laying the cable 4, it is necessary to close all open cable bushings 19a, 19c, 19d, as well as the occupied cable bushing 19b, once again with an appropriate closure means on the inside and outside or along the entire length. This may be done with appropriate closure plugs or closure caps or the like, or also with appropriate casting or caulking means introduced in the cable bushing 19a, 19b, 19c, 19d. Closure means may be used having the most comparable possible heat transfer coefficient to the frame 11 itself. The closure means by which the occupied cable bushing 19b is closed also has a tension relief, absorbing and compensating for any tensile stress acting on the cable 4.

[0029] Besides closing the cable bushings 19a, 19b, 19c, 19d, it is also conceivable to deliberately leave open one or another cable bushing in order to make possible a constant ventilation of the room through the open cable bushing.

[0030] FIG. 2 shows a window 9 in which the cable bushings 19a, 19b, 19c, 19d are open at the factory, and thus not closed. The individual bushing closure is done only after the installing of the window 9. On the contrary, FIG. 3 shows basically the same window 9, but in which the cable bushings 19a, 19b, 19c, 19d are closed at the factory by corresponding closure elements 20a, 20b, 20c, 20d. These closure elements 20a, 20b, 20c, 20d can be closure plugs, for example, which either reach through the entire frame or are installed in the frame 11 at the outside and inside and are finally flush with the inner and outer frame surface. That is, the frame 11 is closed and sealed at the factory. After the installation of the window 9, it is only necessary to remove the closure element or elements 20a, 20b, 20c, 20d of those cable bushings 19a, 19b, 19c, 19d, through which a cable 4 will afterwards be led, for example by axial pressing or pulling out from the corresponding cable bushing 19a, 19b, 19c, 19d. Consequently, this variant allows steps to be taken at the factory so that the frame 11 is tight and optimally designed in terms of heat transfer coefficient, while at the same time affording the simple possibility of opening one or more of the cable bushings 19a, 19b, 19c, 19d as needed.

[0031] The window 9 shown in FIGS. 2 and 3 is suited to both installation in a new construction, where it is installed in an as yet unoccupied window opening, and to retrofitting in an already existing construction, where an already existing window is to be removed from the window opening. For this, the pivot frame needs to be dismounted and the anchored frame removed from the soffit and then the frame 11 of the new window 9 is installed.

[0032] If such major work on the masonry is not desirable in the case of a retrofitting, one can use a window 9 as described herein with the embodiment shown in FIG. 4. FIG. 4 shows once again the masonry 6, where a window is already installed in the window opening. This comprises a frame 21 as well as a swivel wing, already dismounted here. That is, the frame 21 is not removed, but instead remains anchored in the masonry 6. The frame 11 of the window 9 has hinge elements 22, which sit on hinge elements 23 of the already existing frame 21. The frame 11 will be anchored in this place. However, to prevent the entire window 9 pivoting with frame 11 and swivel wing 14, the frame 11 comprises a locking means 24, such as a pivoting bolt, which can be moved by a key from a release position, in which it lies in the frame 11, to a locking position, in which it protrudes from the frame 11 to the side and engages with a corresponding bolt pocket on the frame 21. This produces a locking of the frame 11 in this place, which can also be locked and then released once more, as described.

[0033] Otherwise, the window 9 is designed here the same as described above. In the example shown, once again it has four cable bushings 19a, 19b, 19c, 19d, which once again are closed for example with corresponding closure elements 20a, 20b, 20c, 20d at the factory and can be opened as needed. Alternatively, it is also possible to leave the cable bushings 19a, 19b, 19c, 19d open at the factory.

[0034] Some embodiments make possible the creation of a possibility for simple leading of any given conduit from the inside of a building to the outside with no major intrusion in its framework. Such a conduit may be an electrical cable, which runs to a charging station outside the house and runs by the shortest possible route from a household connection or circuit box to the outside through the window described herein. The window described herein can be used both in new and existing construction. By providing multiple cable bushings, the possibility also exists of leading multiple cables to the outside, and the cable bushings can also differ in cross sectional area and/or cross sectional shape, in order to lead cables of different thickness or shape in the best possible manner. Some embodiments also allow a simple replacement of a cable already led through a window as described herein by another possibly stronger or weaker cable, as well as simplifying the retrofitted laying of further cables through it, for example when a further charging station is to be connected afterwards, possibly charging with a higher power. The basic functionality of the window remains naturally assured in all forms of application.

[0035] German patent application no. 10 2021 131526.3, filed Dec. 1, 2021, to which this application claims priority, is hereby incorporated herein by reference in its entirety.
