Abstract
ABSTRACT OF THE DISCLOSURE
A window stay restricts opening of a hinged window leaf by providing an arm connected between the window and a fixed frame. At one end, the arm is connected to a slide which runs in a channel as the window is opened and closed and which engages a stop to limit the opening movement of the window. The slide can be rotated relative to the channel to a position in which it can be disengaged from the channel to allow the arm to be disengaged from the channel so permitting unrestricted opening of the window in, for example, an emergency.

Description
2057~ ~
BACKGROUND TO THE INVENTION
1. Field of the invention The invention relates to stays for restricting the opening of a window relative to a fixed frame on which the window is hinged and more particularly to the sides of such stays.
BACKGROUND TO THE INVENTION
1. Field of the invention The invention relates to stays for restricting the opening of a window relative to a fixed frame on which the window is hinged and more particularly to the sides of such stays.
2. Brief reviaw of the prior art Known window stays comprise a channel which is usually mounted on a fixed frame, and an arm having one end for connection to the hinged window and the other end pivotally connected to a slider which is carried by the channel for sliding movement along the channel as the leaf is opened out of the frame. When the slider reaches the end of the channel no further opening movement is possible.
Such stays are useful for, for example, limiting the opening of a window to an extent such that a person, particularly a child, cannot fall out of the window.
Such restricted opening can, however, be a disadvantage.
For example, in the case of an emergency it may be desirable to be able to open the window more widely so that persons can climb out of the window and escape a 2 2~57~16 fire. Alternatively, it may be desirable to be able to open a window to a greater extent to clean the window or paint the window.
SUMMARY OF THE INVENTION
According to the invention, there is provided a stay for connection between a fixed frame member and a closure member pivotally mounted on the frame for movement into and out of the frame member, the stay comprising a channel mountable on one member and an arm pivotally connected at one end to a slide movable in the channel to limit the relative opening movement of the members and for pivotal connection at the other end to the other member, the slide being disengagable from the channel for unlimited relative opening movement of the members.
Thus, by providing a modified form of slide, the arm can be disengaged from the channel.
The following is a more detailed description of an embodiment of the invention, by way of example, in which:-BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a plan view of a stay comprising a channelmember, a restrictor arm, a slide and a brac~et, 3 2~7~
E`igure 2 is an end view of the channel member of Figure 1, Figure 3 is a side elevation of the slide of Figure 1, Figure 4 is an end view of the slide of Figures 1 and 3, Figure 5 is an underneath plan view of the slide of Figures 1, 3 and 4, and Figure 6 is a side elevation of a section oE the channel member of Figure 1 showing the slide and a pGrtiOn of the restrictor arm and also showing in broken line a tool for lifting an end of the slide.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
As best seen in Figure 1, the stay comprises a channel member 10, a restrictor arm 11, a slide 12 and a bracket 13.
The channel member 10 is formed by a base 14, side walls 15 and, inwardly directed flanges 16 extending from the edges of the side walls remote from the base 14. Thus the channel member 10 provides two inwardly directed U-shaped guide channels 17 (best seen in Figure 2~.
Each end of the channel member 10 is provided with a stop 4 20~7~1 6 l9 and a hole 20. The holes ~0 are to allow the channel member to be attached to a fixed window frame (not shown) by screws (not shown). The purpose of the stops 19 will be described below.
The restrictor arm ll has one end pivotally connected to the bracket 13 to allow the restrictor arm 11 to be connected to a window leaf mounted on the fixed frame by hinges (not shown). For this purpose, the bracket is provided with screw holes 21.
The opposite end of the restrictor arm 11 is connected to the slide 12 which in turn is carried by the channel member 10. The slide 12 is of a flexible material and includes a body 22 of generally rectangular shape and of the same width as the channel member 10 so that the edges of the undersurface 23 of the body 22 can slide on the outer surfaces of the flanges 16. A leg 24 projects from the undersurface 22, passes between the flanges 17 and carries at its end a shoe 25. The shoe 25 is generally rectangular in shape with its longer dimension arranged normal to the length of the channel member lO so that opposed ends of the shoe 25 project into respective channels 17. In this way, the slide 12 can slide along the channel member lO limited in this movement only by engagement with the stops 20. The slide 12 cannot be 2~7~1~
disengaged from the channel because of the engagement between the shoe 25 and the channels 17.
The side edges 26 of the shoe 25 are spaced by a distance that is less than the gap between the inner edges of the flanges 16.
boss 27 also projects from the undersurface 22 of the body 21 at a position spaced from the leg 24, and this boss 27 fits between the inner edges of the flanges 15 to prevent rotation of the slide 12 about the leg 24.
In use, the channel member 10 is mounted on the fixed frame and the bracket 13 is connected to a leaf which can be opened out of and closed into the fixed frame. The arm 11 limits the degree of opening movement of the leaf by engagement of the shoe 25 with one of the stops 20.
In order to allow unrestricted opening of the leaf, the end of the body 22 carrying the boss 27 is flexed upwardly by use, for example, of an L-shaped tool 28 of the kind shown in broken line in Figure 6, to li.ft the boss 27 out of the channel member 10 so that the end of the body 22 projects away from the channel. The body 22 can then be rotated through 90 until the side edges 26 of the shoe 23 are parallel to the guides lS. In this position, the 20~7~16 shoe 21 can be lifted out of the channel member 10, so releasing the arm 11 from its connection with the channel member 10 and allowing unrestricted opening of the leaf.
The shoe 23 can be re-engaged by a reverse action. It will be appreciated that this allows easy release of the arm 11 in an emergency, but not such easy release that it can be effected by a child, so giving a degree of security.
It will be appreciated that a slide of the kind described above with reference to the drawings could be fitted to any known restrictor stay of suitable type.
Such stays are useful for, for example, limiting the opening of a window to an extent such that a person, particularly a child, cannot fall out of the window.
Such restricted opening can, however, be a disadvantage.
For example, in the case of an emergency it may be desirable to be able to open the window more widely so that persons can climb out of the window and escape a 2 2~57~16 fire. Alternatively, it may be desirable to be able to open a window to a greater extent to clean the window or paint the window.
