Definitions
- the invention relates to a window stay as described in the preamble of claim 1 and as known from NL-A-7405631.
- This known window stay has a complicated structure and cannot not be manufactured cheaply as the second fixing element must be provided with a bearing bush for the shaft which constitutes the second cross axis and must also accomodate the locking cam.
- the invention aims to provide a window stay with a cheap structure and without extra elements in which the coupling pieces, and thus the two arms connected thereto, are directly locked together in the swung-aside position of the stay.
- Fig. 1 is a first side view of the window stay according to the invention in the half extended position.
- Fig. 2 is a second side view, viewed from the other side, of the window stay in this position.
- Fig. 3 is a top view of the window stay in the collapsed, but not yet swung-aside position.
- Fig. 4 is a top view of the window stay in the swung-aside position, in which the two arms are locked together.

- Fig. 8 is a perspective bottom view of the second coupling element.
- Fig. 9 is a perspective top view of the first coupling element.
- Fig. 10 is a side view of the end of the first arm.
- the window stay comprises in the usual manner a first arm 4 and a second arm 6, which are hingedly connected to each other by means of a first pin 8 disposed at right angles to the lengthwise direction of the arms.
- the first arm 4 is hingedly connected, by means of a second pin 10 parallel to the first pin 8, to a first coupling element 12; said coupling element is supported around a first cross pin 14 which is at right angles to the first and second pins (and which will thus in practice be standing vertically) by a first fixing component 16, which is fixed with screws 18 on the frame 20.
- the second arm 6 is connected, by means of a second hinge pin 22 which is at right angles to the pins 8 and 10, to a second coupling element 24, which is coupled by means of a hinge pin 26 which is parallel to the pins 8 and 10 (and which is thus in practice horizontal), to a second fixing component 28, which is fixed on the frame 32 with screws 30.
- the second arm carries the operating handle 34 with which the window stay can be taken to the closed, half open and open position.
- the window stay corresponds to the one which is known from, for example, Dutch Patent 133703 and German Patent 1,708,425, both in the name of applicants.
- the window stay can be brought into the collapsed position, in which the arm 4 lies without the arm 6 - see Fig. 3 -and then, by turning in the direction of the arrow 36 about the pins 14 and 22, both vertical and lying in line with one another, to the position shown in Fig. 4, in which the window stay is parallel to the window and thus does not constitute a cumbersome obstacle sticking into the room.
- This known window stay is improved according to the invention in that the two arms in the foldedaway position shown in Fig. 4 are locked in the following way.

- the wall 42 is partially cut away, while the wall 44 has a locking lip 46 which is flanged inwards over an angle of about 60 degrees.
- the second coupling element 24 (see Figs. 6 and 8) is also essentially U-shaped with a bottom 50 and the end walls 52, 54 projecting therefrom.
- the wall 54 is L-shaped, so that an opening 56 is determined, which in the collapsed state of the window stay (Fig. 3) lies opposite the hook 46.
- the result of this design is that, when the window stay is moved from the position shown in Fig. 3 to the position shown in Fig. 4, the hook 46 falls behind the upright edge 58 of the leg 54a of the L-shaped wall 54, which causes the window stay to lock in the closed position, since the bottom edge 46a of the hook 46 rests against the top edge 54b ⁇ of the leg 54b.

Abstract
Description
- The invention relates to a window stay as described in the preamble of
claim 1 and as known from NL-A-7405631. - In this know window stay the locking of the stay in the swung-aside position is achieved by virtue of the fact that in the swung-aside position a locking cam, connected to the shaft which constitutes the second cross axis and is supported by the second fixing element, lies behind an upstanding edge provided on the first fixing element. As this second fixing element is connected to the window the window thus is locked in the closed position.
- This known window stay has a complicated structure and cannot not be manufactured cheaply as the second fixing element must be provided with a bearing bush for the shaft which constitutes the second cross axis and must also accomodate the locking cam.
- The invention aims to provide a window stay with a cheap structure and without extra elements in which the coupling pieces, and thus the two arms connected thereto, are directly locked together in the swung-aside position of the stay.
- This object is achieved with the measures described in the characterizing part of the main claim.
- The enclosing of the locking hook in the swung-aside position of the window stay results in a very effective locking of the two arms, which means that even when great forces are exerted on the frame the ends of the arms cannot move away from each other.
- The invention is explained with reference to the drawing.
- Fig. 1 is a first side view of the window stay according to the invention in the half extended position.
- Fig. 2 is a second side view, viewed from the other side, of the window stay in this position.
- Fig. 3 is a top view of the window stay in the collapsed, but not yet swung-aside position.
- Fig. 4 is a top view of the window stay in the swung-aside position, in which the two arms are locked together.
- Fig. 5 is a top view of the end of the first arm with the first coupling element, viewed in the direction of the arrow V in Fig. 1.
- Fig. 6 is a side view of the ends of the arms in the collapsed state of the window stay; and
- Fig. 7 is an end view of the window stay in the collapsed and swung-aside position in the direction of the arrow VII in Fig. 4.
- Fig. 8 is a perspective bottom view of the second coupling element.
- Fig. 9 is a perspective top view of the first coupling element.
- Fig. 10 is a side view of the end of the first arm.
- The window stay according to the invention, indicated in its entirety in the figures by the
reference number 2, comprises in the usual manner afirst arm 4 and asecond arm 6, which are hingedly connected to each other by means of afirst pin 8 disposed at right angles to the lengthwise direction of the arms. Thefirst arm 4 is hingedly connected, by means of asecond pin 10 parallel to thefirst pin 8, to afirst coupling element 12; said coupling element is supported around afirst cross pin 14 which is at right angles to the first and second pins (and which will thus in practice be standing vertically) by afirst fixing component 16, which is fixed withscrews 18 on theframe 20. - The
second arm 6 is connected, by means of asecond hinge pin 22 which is at right angles to thepins second coupling element 24, which is coupled by means of ahinge pin 26 which is parallel to thepins 8 and 10 (and which is thus in practice horizontal), to asecond fixing component 28, which is fixed on theframe 32 withscrews 30. - The second arm carries the
operating handle 34 with which the window stay can be taken to the closed, half open and open position. - Up to this point the window stay corresponds to the one which is known from, for example, Dutch Patent 133703 and German Patent 1,708,425, both in the name of applicants. The window stay can be brought into the collapsed position, in which the
arm 4 lies without the arm 6 - see Fig. 3 -and then, by turning in the direction of thearrow 36 about thepins - This known window stay is improved according to the invention in that the two arms in the foldedaway position shown in Fig. 4 are locked in the following way.
- The essentially U-shaped
first coupling element 12 comprises (see Figs. 5 and 9) thebottom 40 and the twoupright walls wall 42 is partially cut away, while thewall 44 has alocking lip 46 which is flanged inwards over an angle of about 60 degrees. The second coupling element 24 (see Figs. 6 and 8) is also essentially U-shaped with abottom 50 and theend walls wall 54 is L-shaped, so that anopening 56 is determined, which in the collapsed state of the window stay (Fig. 3) lies opposite thehook 46. The result of this design is that, when the window stay is moved from the position shown in Fig. 3 to the position shown in Fig. 4, thehook 46 falls behind theupright edge 58 of theleg 54a of the L-shaped wall 54, which causes the window stay to lock in the closed position, since thebottom edge 46a of thehook 46 rests against the top edge 54bʹ of theleg 54b. - In order to avoid the inwardly projecting
hook 46 from being in the way when the window stay is fully extended - shown partially in Fig. 10 - provision is made at the end of thearm 4 for arecess 60 to take saidhook 46. This recess can be seen in Fig. 10.
