Tilt and turn windows,

The invention relates to a tilt and turn window * that is, a window that to open both rotate around a vertical axis and tilt around a horizontal axis located at the bottom of the window leaves.

Windows of this type are installed in a wide variety of buildings because of their obvious advantages, since they offer good ventilation without drafts when opened by tilting, and intensive ventilation and easy cleaning options when opened by turning.

For practical use, such windows must be very easy and safe to handle. It is necessary for this that on the one hand, both types of opening by actuating only one handle can be obtained without any other measures are required, and on the other hand that the opening of the window at Tilting takes place very smoothly, i.e. the window during the tilting movement does not have to be specially kept. In addition, the operation of the handle must not require too much effort.

Tilt and turn windows are already known. However, with some types of such known windows, for the transition from one type of opening to the other, the window sash with respect to the window frame has to be

309828/0412

Slide to lock the horizontal or vertical axis of rotation. This additionally required operating step does not lead only to trouble if the window is no longer new, but rather the shift also complicates the seal between the window «, floor and window sash

The invention is intended to create a tilt and turn window »that overcomes these disadvantages.

This task is solved by a vertical tilt and turn window that has a rectangular stick and a window sash held on a frame, which is arranged around a vertical edge of the Window sash coinciding vertical axis or a coinciding with the lower horizontal edge of the window sash horizontal axis is rotatable and is characterized according to the invention by a holder with a vertical and arranged at its angle coinciding with the intersection of the two axes a horizontal pin; at the second lower angle and at that the vertical axis defining the upper angle provided devices, which a pivot point of the window sash with respect to the Can form window frames; as well as a linkage arranged on the two sides of the window which do not serve as an axis of rotation, which through Shifts alternately forms one of the two pivot points and releases the other and fixed with a cam that can be rotated about an axis is connected, which has such an outline that certain parts of its work surface move the linkage assembly, while other parts do not move the linkage.

According to.' In a first embodiment, the linkage is arranged in a cavity in the window frame.

According to a second embodiment, the linkage is arranged in the hollow frame of the window sash.

The right-angled wishbone 10 is firmly verfcundene with the stick 2 and through a bore 26 of the wishbone 10 going horizontal axis 24 pivotable. The wishbone 10 has a second groove 28 in which a with the upper end of the rod .12 firmly connected pin 30 is displaceable. At its lower end, the rod 12 carries a pin 32. Approximately in the middle is the Bar 12 is provided with two horizontal arms 34 and 36 which include a cam 38 which is perpendicular to the window plane Shaft 40 is firmly connected. On the same shaft, a bolt 42 is fastened, which is formed by a bolt formed in the wall of the stick 2 Slot 44 can protrude from the stick. The cam wijd through the handle 46 attached to the end of the shaft 40 is rotated.

The window sash 4 consists of a glass pane or double glass pane 48, which is bordered on its horizontal edges by metal bars 50 and 52 of a frame firmly connected to the pane 48 * This frame can enclose only two or all four sides of the pane 48 » 4 shows an example of a type of fastening of the transverse strip 50 to the pane 48. The transverse strip 50 has an H-profile, between the two lower legs of the edge of the pane 48 is clamped by screws 54, which are clamped against one that surrounds the pane Press elastic seal or packing 56. The disk 48 can also be glued directly to the profile strip.

The window sash 4 is on the one hand about the horizontal axis YY ¹

309828/0412

and on the other hand articulated rotatably ^{about the vertical axis XX 1.} Two prismatic end pieces 58 and 60 are provided for the articulation according to YY ¹ , each of which is provided with a horizontal pin 62 and 64, respectively, which engage in a bore 66 provided in the window sash 4 parallel to its lower edge. Each end piece 58 and 60 is firmly connected to a torsion bar 66 or 68, the other end of which is firmly connected to the window sash 4 * The end piece 58 is also provided with a groove 70 which is open towards its lower end and which is used to receive the pin 32 the rod 12 is determined. The lower part of the end piece 60 has a vertical pin 70 which engages in a cylindrical bore 74 formed in the stick 2. On its upper horizontal edge, the window sash 4 carries a vertical pin 76, which has the same axis as the pin 72 and penetrates into a seat 78 formed in the floor 2 when the window sash 4 is closed. The articulation devices are described and shown here in a simplified manner in order to better explain the mode of operation of the window. According to a preferred embodiment, the torsion bars 66 and 68 are attached to the window sash in that their free end is each connected to a prismatic block, these blocks in one inside. the cross bar 52 formed slide rail are displaceable, which has the same axis as this. In addition, by adjusting the length of each torsion bar between one of the holders and the associated prismatic block, the maximum opening of the window when tilting can be adjusted. Each torsion bar can advantageously consist of torsion blades arranged next to one another
