Abstract
ABSTRACT OF THE DISCLOSURE
Screened windows have a movable closure panel and a mesh screen fixed in the aperture, e.g. to allow ventilation but exclude insects; a securable stay controls the degree of opening of the panel through the screen. The invention provides a device for securing the stay controlling the movable panel, the parts of the device being so shaped that they fit closely around the stay when it is locked in place, so as to minimise clearance between the stay and screen.
The invention may also be applied to door and shutters and the like.

Description
~0659~q 1 This invention relates to windows and the provision of screens therefor, e.g. to exclude insects. The term "window" is intended to include all closable apertures in e.g. a building or a caravan, and may thus refer to doors or shutters, whether glazed or not.
In hot climates e~pecially, windows are often left open, even at night, so as to allow free circulation of air. In order to keep out insects such as mosquitos, it is known to fit the window openings with mesh screens.
With hitherto known constructions, however, an aperture has been left in the screen to allow a window stay to pass through; the protection against insects offered by such arrangements was thus incomplete.
According to one aspect of the invention, there is provided a mesh screen panel for fitment within a window frame, said panel including a securing device having means engageable with a window stay passing there-through whereby to lock the stay in place. The device is shaped to fit closely around the stay when said means are so engaged (the term "fit closely" is herein used to denote not necessarily an exact tight or even sliding fit, but extends also to situations which do leave slight gaps) in order to minimise the possibility of insects entering via the window. The term mesh screen panel here includes the parts that are fast with it.
The invention also provides a window assembly comprising a mesh screen panel as just defined, a closure panel movable relative thereto, and a stay for control of the movement.
3o 106591~7 l Preferably, the stay comprises a number of location holes in a rigid elongate member, the securing device including a peg which can be moved into any of said holes according to the degree of window opening desired.
In a preferred embodiment of the invention, the securing device comprises a first, fixed plate and a second plate slidable relative thereto incorporating a peg for engagement with the stay, said plates being profiles to fit closely around respective sides of the stay cross-section.
In the accompanying drawings:-Fig, 1 is a general view of a window according tothe invention; and Fig. 2 shows part of Fig. 1 to an enlarged scale.
Referring to Fig. 1, there is shown a window assembly 2 comprising an outer frame 4 set in a wall 6.
A glazed window panel 8 is hinged to the upper part of the frame 4 to open outwards of the wall. A mesh screen panel comprising a frame 12 and a glass-fibre mesh 10 is secured in outer frame 4. A rubber seal (not shown) is fitted to panel 8 to seal it against frame 4.
An elongate stay 14 is pivotally attached to the window panel at 16. ~he stay has a series of holes 18 along its length which are used in conjunction with securing device 24 to control the degree of window opening;
this is described more fully below. In order to lock the window shut, the stay is pivoted to lie alongside the lower horizontal part of frame 12, pressed against post 20 and slipped under a lip on catch 22.
3o 11)6S9~7 l The securing device is shown in more detail in Fig. 2.
A metal back plate 26 is screwed to frame 12 at 28 and has its side edges 30 turned over to provide a guide channel for a slidable locking plate 32. A screw 34 acting on spring washer 36 is located in a slot 38, so that the locking plate is secured to the back plate but can slide up and down relative to it. A tab 40 is used to effect such movement.
The back plate 26 incorporates an aperture 42 through which stay 14 can pass; only the lower part of this aperture is visible in the figure and is configured to match the profile of the lower side of the stay - in this case an aluminium extrusion of inverted U-form cross-section. The aperture thus comprises two downwardly-directed arms 42a with a tongue 44 projecting between them.
The lower edge of the locking plate 32 is similarly profiled to match the upper part of the stay cross-section.
The cut-out portion is additionally provided, however, with a peg 46 for location in any one of holes 18 of the stay.
Thus when the locking plate is slid to its lower position (as shown in ~ig. 2) not only does the engagement of the peg in the stay hold the window open at any desired angle, but the respective profiles of the backing and locking plates also cooperate to fit snugly around the stay to deny insects any passage.
In the embodiment just described the various frames, as well as the stay, are made from aluminium extrusions;
other materials, such as wood or metal castings can also be used. Similarly, any suitable mesh material can be employed, the choice of mesh size depending on the intended application.
10659~7 l A number of other arrangements are envisaged as embodying the invention. For example, it may not always be convenient that the backing plate exhibit a tongue 44 t~ fit into the underside of the stay, for it will normally be necessary for pivot 16 to pass through the securing device when the window is shut; the unillustrated portion of aperture 42 may provide sufficient passage depending on the pivot arrangement) when the slidable plate is lifted. The same problem may arise if the aperture in the backing plate is configured to fit closely around the whole of the stay cross-section, with the sliding plate having a locking function only.
In such cases, the stay cross-section may be selected so ~ to display no re-entrant portion, e.g, a square instead of U-form cross-section, and the tongue can be dispensed with. Alternatively, the stay may have transverse webs adjacent holes 18 so as to give an equivalent cross-section at those regions only. Another solution, which is more economlcal in terms of metal used, and in which the stay can be made as an extrusion, is that the holes 18 be formed as transverse slots extending the whole width of the stay between the arms of the U.
Peg 46 can then be enlarged to replace tongue 44 whilst still acting as an engagement member.
