Abstract
Description
- This invention relates to a hinge or friction stay of the kind which comprises a track with a nose cap at one end, a bar pivoted to a strut, a link connecting the bar to a slider on the track, and a brace connecting the strut to the slider. A hinge or friction stay of this kind is disclosed, for example, in EP-A-0142999. In this type of hinge, or friction stay, the track is normally connected to the window or door frame and the opening door or window light is attached to the bar. Normally two such hinges or friction stays are used to support a window or door at the bottom or top of the window or door or sometimes in the case of a window on the two sides.
- A disadvantage of existing hinges or stays of this kind, is that they do not allow the window or door to open far enough to give adequate egress. Particularly in the case of a window, the hinge or stay allows a limited opening of the window which is insufficient to provide a clear window opening through which a person could escape in the event of fire.
- An object of the invention is to provide such a hinge or friction stay, particularly for use with a side-hung window (i.e. a window in which the stays are mounted along the top and bottom edges of the window frame) which will allow sufficient opening of the window light to enable the window to be opened sufficiently for use as an emergency escape exit or sufficiently to allow the window to be cleaned from both sides without the need to go out of the building.
- According to the present invention as defined in
independent Claim 1 there is provided a window hinge, or friction stay, comprising: - a track with a nose cap at one end;
- a bar pivoted to a strut;
- a link connecting the bar to a slider on the track; and
- a brace connecting the strut to the slider, characterised in that the strut is pivotally mounted on a second slider on the track, the second slider having its movement restricted by two spaced stops, and in that the first slider has a limited degree of free movement and is resiliently biased away from the nose cap, the arrangement being such that when the hinge is opened, one end of the strut moves bodily outwards, thus allowing the bar carrying the window to swing to one side of the window frame and to provide a substantially unimpeded window opening or at least a window opening in which a substantial proportion of the opening is unimpeded.
- The bar will normally carry a nose member which cooperates with the nose cap so as to pull the hinge fully into its closed position during the closing movement, and the first movement during opening is assisted by the spring so that the first slider moves to a limited extent away from the nose cap thus allowing the nose member to clear the nose cap before further opening movement takes place. The hinge may have an additional link or brace located between the bar and the brace, so as to enable the hinge to be used with heavier types of windows as defined in Claim 2.
- In the accompanying drawings:
- Figure 1 is a diagrammatic elevation of a window supported in a frame by two hinges incorporating the present invention;
- Figure 2 is a diagrammatic plan view of the same window and window frame showing the window in its open position and showing one of the supporting hinges in chain dotted line;
- Figure 3 is a plan view of the lower of the two hinges or stays supporting the window, the hinge or stay being shown in its fully open position;
- Figure 4 shows the nose end of the same stay when it is in its fully closed position; and
- Figure 5 is a plan view of the same stay when it is in its partially open or nearly closed position.
- In Figure 1 is shown a
window light 10 supported by two friction stays 11 and 12 at its top and bottom in awindow frame 13. - As seen in Figure 2 the
window light 10 is movable to a position in which it is at one side of the frame and substantially clear of it so that the open frame is substantially unimpeded by the window. - The hinges or friction stays which enable this effect to be achieved are illustrated in Figures 3, 4 and 5. Figure 3 shows the lower of the two
hinges 12. The hinge consists of atrack 14 which has at one end anose cap 15 attached to the track by arivet 16 or other means. At the other end of the track is arivetted stop 17. - A
strut 18 is pivoted at 19 to aslider 20 and the movement ofslider 20 is restricted bystop 17 and asecond stop 21. - A
strut 18 is connected by arivet 22 to abar 23 carrying at one end anose member 24. The bar is also connected via alink 25 to asecond slider 26. Abrace 27 connectsstrut 18 toslider 26. Betweenslider 26 and the nose cap is mounted aspring 28. Movement of theslider 26, which is biased byspring 28, is limited bystop 29. -
Stop 29 is not absolutely essential, it is only there to allow space for afixing hole 30. If the fixing hole were not required then astop 21 could perform the function of limiting movement of bothsliders - It will be seen that with the hinge in its open position as shown in Figure 3 the
bar 23 which carries the window light is located towards the right-hand end of the track and almost at right angles to the track thus leaving a large unimpeded area of the window aperture. This is achieved by having thestrut 18 carried by a slider with substantial freedom of movement between thestop strut 18 has a fixed pivot point at the end of the track remote from the nose cap, i.e. wherestop 17 is. - The construction used would be difficult to operate were it not for a further feature of the invention i.e. that the
first slider 26 has only a limited degree of movement but sufficient movement to allow thenose 24 to clear thenose cap 15 during the initial opening movement of the hinge. As seen in Figure 4, in which the hinge is closed, there is asmall gap 31 between thestop 29 and theslider 26. - When the hinge is opened, as seen in Figure 5, the
spring 28 biases theslider 26 so that thegap 31 will be closed as theslider 26 moves towards and abuts stop 29. This initial movement of theslider 26 along the track causes thenose 24 to clear thenose cap 15 and thus prevents the nose fouling the cap during the opening movement. - The invention may be applied for example to friction supported stays or hinges of a type shown in our European Patent Application 0112681Al, or in U.K. Patent Application 2144173A or in U.K. Patent Application 2081803B all of which are examples of friction stays manufactured by the present Applicants.
- The
spring 28 although shown as a wire type spring may be replaced by a Z shaped spring or a coil spring where there is sufficient room to put such a spring in. - An additional link or brace may be provided between bar and brace to enable the hinge to be used with heavier type windows.
