Description

[0001] The present invention relates to a sliding window or sliding door arrangement with a fixed frame and at least one sliding sash, which is provided with a lift-and-slide fitting by means of which the sliding sash can be adjusted into a raised position in which it can be horizontally displaced.

[0002] Sliding window or door systems with sliding sashes are commonly known, for example, as manually operated patio or balcony windows or doors. With conventional sliding window or door systems, a secure ventilation position is not usually possible regardless of the horizontal sliding position of the sash, as the open sash, when lowered, is only prevented from moving by friction caused by its weight. However, with sufficient force, this friction can be overcome, and the lowered sash can be opened further or even fully.

[0003] EP 1 681 417 A2 discloses a fitting with a guide rail, an actuating linkage and a locking device which can be coupled to a carriage of a sash, wherein a bolt can be moved into a locking position when the sash is lowered.

[0004] WO 2010 / 007567 A1 discloses a carriage for a sliding door, comprising a frame and a roller assembly, wherein the frame can be movably coupled to the sash via a connecting element to allow the sash to be raised and lowered. An adjustable sliding element can be fixed to the frame by means of a bolt.

[0005] The invention is therefore based on the objective of providing a sliding window or sliding door arrangement of the type mentioned above, with which freely selectable secured ventilation is possible.

[0006] According to the invention, this problem is solved by providing the frame with toothing and making the sliding sash adjustable to a lowered position in one or more, in particular any, horizontal displacement positions, in which it can be locked via the frame-side toothing. Preferably, the upper area of ​​the sliding sash is provided with at least one locking element, in particular an eccentric or bolt, which interacts in particular with an upper guide rail of the frame and is adjustable with the raising and lowering of the sliding sash such that, when the sliding sash is lowered, the locking element prevents the sliding sash from being lifted unlawfully.

[0007] This design allows for freely selectable and secure ventilation regardless of the sliding sash's horizontal position. The locking element prevents the sliding sash from being lifted out of its lowered position, as it is adjustable to prevent unauthorized lifting when the sash is in the lowered position. The frame-side toothing prevents accidental or unwanted horizontal movement of the sash when it is in the lowered position.

[0008] Advantageously, the sliding sash is equipped with a counter-toothing mechanism that engages with the frame-side toothing when the sash is lowered, thus locking the sash in place. When the sash is raised, the toothing between the sash and the frame is disengaged, allowing the sash to be moved in the usual manner.

[0009] According to a further advantageous embodiment of the sliding window or sliding door arrangement according to the invention, the sliding sash is provided with at least one gear meshing with the frame-side teeth, which is locked when the sliding sash is lowered in order to lock it. When the sliding sash is raised, this gear is released, so that the sliding sash can again be moved freely horizontally. In this embodiment, the mating teeth of the sash are thus formed by a gear that can be locked and released in its rotation.

[0010] The sliding sash can be mounted in the frame, in particular by means of sliding or roller guides. The frame-side toothing is preferably located in the area of ​​a lower running or sliding rail, and the toothing or gear associated with the sliding sash is located on the underside of the sliding sash. In principle, the toothing or gear can also be arranged in the upper area of ​​the frame and the sash. Even with this arrangement, when the sash is raised, the toothing between the sash and frame must be disengaged, or the gear must be free to rotate, while when the sash is lowered, the toothing engages, or the gear is locked in place.

[0011] If at least one eccentric is provided to prevent the sliding sash from being lifted out in its upper area, this can be designed, in particular, as an eccentrically mounted roller guided on an upper guide rail of the frame. Each eccentric is preferably designed as an eccentrically mounted grooved roller into which the upper guide rail of the frame engages.

[0012] The lift-and-slide fitting of the sliding sash preferably includes a gearbox equipped with a handle by which the sliding sash can be adjusted between its lowered and raised positions.

[0013] Preferably, the locking element, in particular the eccentric or the bolt, can also be adjusted via the handle of the gearbox.

[0014] If the sliding wing is provided with at least one gear instead of a counter-gear, then this gear can also be advantageously locked or released via the handle of the gearbox.

[0015] The invention will be explained in more detail below with reference to an exemplary embodiment and the drawing; in this drawing: Fig. 1 a schematic representation of an exemplary embodiment of a sliding window or sliding door arrangement according to the invention and Fig. 2 a schematic cutaway partial representation of the sliding window or sliding door arrangement according to Fig. 1, cut along line AA.

[0016] Fig. Figure 1 shows a schematic representation of an exemplary embodiment of a sliding window or sliding door arrangement 10 according to the invention, with a fixed frame 12 and at least one sliding sash 14, which is provided with a lever-slide fitting by means of which the sliding sash 14 can be adjusted into a raised position in which it can be moved horizontally.

[0017] The frame 12 is provided with a toothing 16 in its lower area. The sliding sash 14 can be adjusted to a lowered position in any horizontal sliding position, in which it can be locked via the toothing 16 on the frame side and in which a gap 32 is created above the sliding sash 14 between it and the frame 12.

[0018] The upper area of ​​the sliding sash 14 is provided with at least one, in the illustrated embodiment with two locking elements designed as eccentrics 18, which in particular are connected to an upper guide rail 20 (see also Fig. 2) of the frame 12 interact and are adjustable with the raising and lowering of the sliding sash 14 in such a way that even when the sliding sash 14 is lowered, an impermissible raising of the sliding sash 14 by the locking elements is prevented.

[0019] The sliding sash 14 can be used as in the Fig. Figure 1 shows, for example, a counter-toothing 22 which, when the sliding sash 14 is lowered, engages in the frame-side toothing 16 to lock the sliding sash 14 and thereby prevent it from moving horizontally. If the locking occurs when the sliding sash 14 is only slightly open, preventing access through the resulting vertical gap, a secure gap ventilation position is created.

[0020] With the sliding sash 14 raised, the toothing between the sliding sash 14 and the frame 12 is decoupled and the sliding sash 14 can again be moved freely horizontally, so that it can be completely closed or opened.

[0021] As an alternative to the counter-gear 22, the sliding sash 14 can also be provided with at least one gear meshing with the frame-side toothing 16, which is blocked in its rotation when the sliding sash 14 is lowered in order to lock it. When the sliding sash 14 is raised, such a gear is released again.

[0022] The sliding wing 14 can be mounted in the fixed frame 12, in particular by means of sliding or roller guides.

[0023] The frame-side toothing 16 can be used particularly in the area of ​​a lower running or sliding rail 24 (see also Fig. 2) be provided. The toothing 16 or the gear associated with the sliding wing 14 is preferably provided on the underside of the sliding wing 14.

[0024] The eccentrics 18 can, for example, be designed as eccentrically mounted rollers guided on the upper guide rail 20 of the frame 12 (see also Fig. 2).

[0025] As particularly evident from the Fig. As can be seen in Figure 2, each eccentric 18 can also be designed as an eccentrically mounted groove roller into which the upper guide rail 20 of the frame 12 engages.

[0026] The lift-and-slide fitting of the sliding sash 14 can in particular include a gearbox which is provided with a handle 26 by means of which the sliding sash 14 can be adjusted between its lowered and raised position.

[0027] Instead of the eccentrics 18, for example, adjustable bolts or the like can also be provided. These can, for example, be extended upwards when the sliding sash 14 is lowered in order to partially or completely bridge the horizontal gap that forms between the sliding sash 14 and the frame 12, and thus prevent the sliding sash 14 from being lifted out.

[0028] The locking element, in particular the eccentrics 18 or the bolts, can also be adjusted via the handle 26 of the gearbox.

[0029] If the sliding wing 14 is provided with at least one gear instead of the counter-gear 22, such a gear assigned to the sliding wing 14 can also be locked or released via the handle 26 of the transmission.

[0030] Fig. Figure 2 shows a schematic cutaway partial representation of the sliding window or sliding door arrangement 10 according to Fig. 1, cut along line AA.

[0031] In this Fig. Figure 2 shows an eccentric 18 designed as a guide, which is eccentrically mounted in a groove 28 of the sliding sash 14. In the present case, the eccentric 18 is designed, for example, as a groove roller into which the upper guide rail 20 of the frame 12 engages.

[0032] Furthermore, in this Fig.2 The lower running or sliding rail 24 of the frame 12, provided with the toothing 16, can be seen, on which the sliding sash 14 is supported, at least in its raised position in which it is horizontally displaceable, by means of rollers 30. At least one roller 30 can advantageously also form the lockable gear. In this case, a central guide projection 34 of the running or sliding rail 24 can be provided with the mating toothing 22. Additionally or alternatively, the toothing 16 can be located laterally next to the guide projection 34 and the mating toothing 22 can be formed on the underside of the sliding sash 14.
