Definitions

  • the invention relates to a window stay, comprising a first arm and a second arm hinged thereto by means of a first axis placed at right angles to the lengthwise direction thereof, of which arms the first one lies, in the folded-up position inside the second one, the first arm being connected, by means of a second axis running parallel to the first axis, to a first coupling part which is supported by a first fixing part by means of a first transverse axis lying at right angles to the first and second axis, while the second arm, by means of a second transverse axis, is connected to a second coupling part which, by means of a third hinge axis running parallel to the first and second axis, is connected to the second fixing part, and the first coupling part is provided with a locking hook which projects inwards from a side face thereof and interacts with a take-up opening in the wall of the second coupling part lying opposite the window stay when it is folded up, all this in such a way that, in the position in which the
  • Such a window stay is known per se from European Patent 0,277,375 in the name of applicant.
  • This window stay is already a considerable improvement on the classic window stay which in the folded-up position can be moved into a position parallel to the window, this being due to the presence of the locking hook which in the turned-away position, in which the window stay is parallel to the window frame, makes it difficult to force the window stay.
  • a slit is formed in the locking hook, running from the bottom edge towards the top edge thereof, which slit, in the folded-up position of the window stay when it is turned against the window, lies opposite the leg of the second coupling part through which the third hinge axis passes.
  • this second coupling part connected to the window is pressed upwards when the window is being forced, said coupling part comes to lie in the slit, as a result of which the window stay remains locked.
  • the window stay comprises in the usual way a first arm 4 and a second arm 6, which are hinged to each other by means of a first axis 8 positioned at right angles to the lengthwise direction of the arms.
  • the first arm 4 is hinged, by means of a second axis 10 running parallel to the first axis 8, to a first coupling part 12; this coupling part is supported, about a first transverse axis 14 which lies at right angles to the first and second axis (and which in practice will thus be vertical), by a first fixing part 16 fixed by means of screws 18 on the fixed frame 20.
  • the second arm 6 is coupled, by means of a second hinge axis 22 lying at right angles to the axes 8 and 10, to a second coupling part 24, which is coupled by means of a hinge axis 26 parallel to the axes 8 and 10, in practice thus horizontal, to a second fixing part 28, which is fixed by means of screws 30 on the window frame 32.
  • the second arm bears the control handle 34, with which the window stay can be moved into the closed, half-open and open position.
  • the window stay can be moved into the folded-up position, in which the arm 4 lies inside the arm 6, and subsequently, by turning about the two then vertical axes 14 and 22 lying in line with each other, can be moved into the position shown in Figure 4, in which the window stay is parallel to the window, and thus does not form an irksome obstacle projecting into the room.
  • the essentially U-shaped first coupling part 12 is composed (see in particular Figure 5) of the bottom 40 and the two vertical walls 42 and 44 projecting therefrom.
  • the wall 44 is composed of the two parts 44a and 44b which merge into each other, and of which the part 44b bears a locking lip 46 turned inwards through about 60°.
  • the wall 42 is partially cut away.
  • the second coupling part 24 (see Figure 3 and Figures 4a - 4b) is also essentially U-shaped, with a bottom 50 from which a first end wall 52 and a second L-shaped end wall, which is made up of the parts 54a, 54b, project.
  • window stay according to the invention corresponds to that which is known per se from European Patent 0,277,375 in the name of applicants.
  • a recess 46a is formed in the locking lip 46.
  • this recess lies opposite the top edge 58 of the leg 54b of the coupling part 24, as shown in end view in Figures 4a - 4c.
  • a burglar trying to force the window stay by placing a crowbar between the bottom edge of the window frame 32 and the fixed frame 20, and thereby exerting a force in the direction of the arrow 60a will press the window frame 32 with the fixing part 28 - and thus the hinge axis 26 and the second coupling part 24 - upwards, so that the position shown in Figure 4b, in which the leg 54b lies in the recess 46a, arises.
