Description

The invention relates to a sliding window device comprising a rectangular window frame for installation in a window opening according to the preamble of patent claim 1.

Very large window formats that can be opened can only be designed as sliding windows. In order to achieve a virtually seamless transition between living space and nature, there is often a desire for frameless glazing, ie glazing in which the frames are not visibly arranged. For this purpose, frame profiles are completely fitted into the floor, ceiling and walls, which accommodate the window elements. Aluminum profiles are regularly used, which absorb the considerable loads of the window elements. EP 2725178 A1 , EP 1953328 A1 , DE19920534C1 and US10494847B1 disclose sash window devices.

In the EP 3 095 946 A1 describes a sliding window device in which the frames are formed from a circumferential plastic profile, in which static elements are introduced on the bottom side, which absorb the loads acting on the window elements via force transmission supports. In the bottom profile part, rollers are also arranged aligned in a straight line, on which the sliding window element rests and via which this window element can be displaced.

This previously known sliding window device is characterized by a subtle, minimalist design in which the window panes seem to float frameless above the floor. However, a closer look at the bottom profile reveals the channel, which is not covered by the sliding window element, and in which the rollers on which the window element is sliding are mounted. This channel with the rollers arranged in it disturbs the overall impression of the otherwise very discreet sliding window device. This is where the invention aims to remedy the situation. The object of the invention is to provide a sliding window device of the aforementioned type in which no channel fitted with rollers can be seen even when the sliding window element is in the open position. According to the invention, this object solved by a sliding window device having the features of the characterizing part of claim 1.

The invention provides a sliding window device in which no channel fitted with rollers can be seen even when the sliding window element is in the open position. Because a horizontal slide-in shaft is arranged parallel to the guide shaft on the side of the first window element and accommodates a slide plate which can be moved in the direction of the guide shaft and to which at least one slat is pivotably fastened and which is prestressed against the second sash by a spring element where the width of the carriage plate and the at least one slat is greater than the width of the guide shaft, when the sliding window element is opened, the guide shaft provided with the roller arrangement and released by the latter is covered by the carriage plate with the at least one slat arranged on it allows.

In a further development of the invention, the slide-in slot is delimited by a cover plate, which is arranged on the base profile at a distance from it and covers it in some areas. In this way, a design in the manner of a drawer compartment is achieved, into which the carriage plate can be moved. The cover plate is preferably of rectangular design and extends as far as the guide shaft.

In an embodiment of the invention, the carriage plate is pivotally connected to a pivot plate which is pivotally connected to a guide plate, the carriage plate being displaceably guided orthogonally to the guide shaft and the guide plate being displaceably guided along the insertion shaft. This enables the guide shaft to be covered following the sliding position of the sliding window element. The carriage plate is preferably prestressed against the second window element by a spring element.

In a further embodiment of the invention, the carriage plate has a guide groove arranged transversely thereto, into which a guide web arranged transversely thereto in the slide-in slot engages. This achieves a guided, straight displacement of the carriage plate. The guide groove is preferably formed by two sliding webs arranged parallel at a distance from one another or by a profile with a C-shaped cross section. Advantageously, the sliding webs or the profile protrude beyond the carriage plate and/or the guide web beyond the slide-in slot.

In a further development of the invention, the cover plate, carriage plate, pivoting plate and/or guide plate and the at least one lamella are formed in the form of thin aluminum or plastic plates. As a result, a visually appealing cover arrangement that can be moved mechanically with little resistance is made possible.

In an embodiment of the invention, the at least one lamella is connected to the underside of the carriage plate facing the bottom profile part. This achieves a connection of the lamella that is concealed by the carriage plate.

In a further embodiment of the invention, the at least one slat is prestressed against the second window element via a respective spring element, preferably a torsion spring. This achieves a mechanical pivoting of the slat through contact with the displaceable window element.

In a further embodiment of the invention, at least two slats are arranged pivotably relative to one another, the slats having two side edges connected to one another at right angles, such that a side edge of all slats complement one another in a pivoted position of the slats to form a straight line. This forms a cover chain which, following the movement of the swivel plate, allows the guide shaft to be covered continuously.

In a further development of the invention, a groove for engaging the carriage part and the slats is arranged on the bottom profile part along the guide shaft opposite the insertion shaft. As a result, good guidance of the at least one slat and a step load capacity are achieved by the carriage part with the at least one slat fastened to it. The groove is preferably formed by a profile with a substantially U-shaped cross section, which is fastened to the bottom profile part.

In an embodiment of the invention, a groove arranged transversely to the bottom profile part for guiding the carriage plate is present on the bottom profile part or in the lateral profile part adjoining this. This supports the guided movement of the sled plate and improves its resistance to footing.

The sliding window device selected as an exemplary embodiment consists essentially of a rectangular window frame 1 which is formed from a circumferential profile which accommodates a fixed window element 2 and a sliding window element 3 and is mounted on a base frame 14 on the bottom side.

In the Figures 2 and 3 shows the lower portion of a sliding window device relevant in the context of the present invention. Details of the upper area with ceilings and side profiles are, for example, in EP 3 095 946 A1 described. The bottom profile part 11 comprises a first inner shaft 111 for receiving the fixed window element 2 and a second guide shaft 112 arranged next to the inner shaft 111 for receiving the sliding window element 3. The inner shaft 111 and the guide shaft 112 are based on an arrangement of webs 113 arranged parallel to one another , are delimited by the channels for receiving static elements 115.

Three channels are arranged in the guide shaft 112 accommodating the displaceable window element 4, with a static element 115 designed in the form of a rectangular rod being inserted in each of the two outer channels for load introduction is pushed onto the base frame 14. The central channel accommodates a roller assembly 16 with support rollers aligned along a straight line.

The support rollers are mounted in a support roller rail 17 , which rests on both sides of the middle channel on the cross braces of the channels receiving the static elements 115 , as a result of which the load is dissipated via the static elements 115 .

Inner shaft 111 and guide shaft 112 are delimited on the outside by vertical support struts 117 which, when the floor-side profile part 2 is installed, are aligned in a building-side installation gap with the outer covering and the top floor of the inner living area. The two shafts 111, 112 are delimited on the inside by a central dome 114.

The inner shaft 111 of the bottom profile part 11 accommodating the fixed window element 3 is covered by an insertion shaft 4 which is delimited by a cover plate 41 which is fastened to the vertical support strut 117 of the inner shaft 111 via an angle piece 42 . The slot accommodates a carriage plate 51 of a locking mechanism 5 .

The closing mechanism 5 consists essentially of the carriage plate 51, a pivot plate 52 pivotably connected thereto and a guide plate 53 which is pivotally connected to the pivot plate 52. In the exemplary embodiment, the carriage plate 51, the swivel plate 52 and the guide plate 53 are made of sheet aluminum.

The guide plate 53 is pushed into two opposite U-profiles 43 arranged on the underside of the cover plate 41 facing the inner shaft 111 , as a result of which the guide plate 53 is slidably mounted under the cover plate 41 parallel to the sliding window element 2 .

The carriage plate 51 has on its upper side facing the cover plate 41 a C-profile piece 511 which engages with a guide web 44 with an I-shaped cross section arranged on the underside of the cover plate 41 . The carriage plate 51 is slidably mounted under the cover plate orthogonally to the guide shaft 112 of the bottom profile part 11 . Furthermore, the carriage plate 51 is guided in a U-profile 121 which is fastened below the cover plate to the profile part 12 which is placed on the bottom profile part 11 on the side opposite the fixed window element 2 .

At its end facing the pivot plate 52, a first lamella 54 is arranged pivotably on the carriage plate 51 below the pivot plate 52, on which a second lamella 55 is pivotably fastened. The two slats 54, 55 have an outer contour in the form of a three-quarter circle, the ends of which merge with one of two straight lines set at right angles to one another. In the exemplary embodiment, the slats 54, 55 are also made of sheet aluminum.

On the support strut 117 of the guide shaft 112, a U-profile 118 is arranged in alignment with this, which is attached to the support strut 11 of the guide shaft 112 via an angle piece 119. In the open position of the displaceable window element 3, the slats 54, 55 with a straight outer edge, which form a straight line in this position, rest together with the carriage plate 51 on the U-profile 118, which accommodates them. The slats 54, 55 are each via a torsion spring (not shown) with its right-angled corner against the displaceable window element 3. The carriage plate 51 is a - biased coil spring against the U-profile 118 - not shown.

The function of the closing mechanism 5 is in the Figures 4 to 6 shown. In figure 4 the sliding window element 3 is in the open position. The slats 54, 55 and the carriage plate 51 rest against the U-profile 118 of the support strut 117 of the guide shaft 112, which accommodates them.

The guide shaft 112 is closed by the carriage plate 51 and the lamellae 54,55. The guide plate 53, which is articulated to the carriage plate 51 via the pivot plate 52, is in a forward position.

If the displaceable window element 3 is pushed in the direction of the closed position, it presses against the slat 54 and rotates it, as a result of which the carriage plate 51 is moved along the guide web 44 in the direction of the inner shaft 111 . As a result, the pivot plate 52, which is articulated to the carriage plate, is pivoted, as a result of which the guide plate is shifted to a rear position ( figure 5 ). If the sliding window element 3 has reached its closed position, the carriage plate 51, slats 54, 55 and pivoting plate 52 are located completely under the cover plate 41 in the insertion shaft 4. In this position, the pivoting plate 52 is in alignment with the carriage plate 51 and the guide plate 53. The Guide plate 53 is in the rear position ( figure 6 ).
