Concealed hinge for a turn-tilt window and such a window equipped therewith

Abstract

The invention discloses a concealed hinge for a turn-tilt window and such a window equipped therewith. Concealed hinge for a turn-tilt window with a fixed frame (2) and leaf (3), composed of a pair of scissors (25) with a first arm and second arm (26,27), that are connected by a central hinge (28) and which are hingeably connected by a first end (29, 30) to a mounting slat (31) that is intended to be mounted on the frame (2), and have a hinge (40, 47) at a second end (32, 33) for coupling to the leaf (3), characterised in that the first arm (26) is connected by its first end (29) to the mounting slat (31) with a fixed frame hinge (34) with a peg (35) that is fastened to the mounting slat (31) and the second arm (27) is connected by its first end (30) to the mounting slat (31) by a shiftable frame hinge (37) with a peg (38) that is shiftably affixed in a guide slot (39) of the mounting slat (31), whereby in the closed situation of the scissors (25), the mounting slat (31) serves as a support for the tilting movement of these scissors (25).

Description

technical field [0001] The present invention relates to a concealed hinge for a window with a fixed frame and rotatable blades. [0002] In particular, the present invention relates to a concealed hinge for a turn-tilt window, which, depending on the position of the operating handle of the window, can turn open about a vertical axis or Tilt open about the horizontal axis. Background technique [0003] Such hidden hinges are installed in a concealed manner between the fixed frame and the blades or are intended for this purpose so that they cannot be seen when the window is closed. [0004] As is known, the vanes are provided along their perimeter with lateral vane lips protruding outwards, whereby in the window closed position the vanes rest on the front of the fixed frame with the intervention of the seal, whereby the vane lip is in the front view Partially overlap the frame. [0005] This blade lip also covers the space between the blade and the fixed frame where the hid...

AI Technical Summary

Problems solved by technology

[0012] Known concealed hinges have the advantage that the horizontal axis (about which the blades can be turned) is relatively far above the bottom profile of the frame of the window, which may be disadvantageous for low windows, for example for windows less than 50 cm in height, due to Their low height only enables limited turning movement with a limited opening angle, because otherwise the bottom blade lip would touch the front of the frame with its seal so that the seal could be pinched or the blade lip damaged

[0013] With the known concealed hinges, the installation of the leaves in the frame is relatively complicated, since in some assembly steps the installer cannot see the hinge and must therefore rely on touch
