Abstract
A casement window stay comprises a stay arm 18 pivottably connected to the window frame 10 end engageable on a peg 20 on the window surround 12 and further includes a clip 24 on the frame 10 that also engages the stay arm for added security. <IMAGE>
Description
SPECIFICATION
Window stays
This invention concerns casement window stays casement window stays usually comprise an arm that is pivotally attached to the casement window frame for movement in both the vertical and horizontal planes relative to the casement window.
Both movements may be simultaneous.
The arm is usually of an inverted generally Ushaped cross-section sized so as to fit snugly over an upstanding peg on the surround for the casement window. The arm can be located on the peg at any desired position so that the casement window is held closed or open to a desired extent.
A problem with such stays is that the arm is not always sufficiently securely held on the peg. Thus, when the window is closed, impact on the casement window frame can cause the arm to jump off the peg and so allow opening and entry by say burglars. The tendency of the arm to jump can be contributed to by the springiness of the pivotal attachment as well as the resilience of the material used for construction of the stays, such as aluminium, die cast material, mild steel or the like.
Furthermore, during transportation of made up windows unwanted opening of the casement can lead to damage thereof.
The object of this invention is to provide a casement window stay having means for preventing or at least reducing the likelihood of the stay arm being too easily released.
According to this invention a casement window stay further includes clip means that is engageable with the stay arm when the window is closed, the clip means being on the casement frame.
The clip means may engage a hole, a slot a groove or a protrusion of the stay arm. The stay arm conveniently has such holes, slots grooves or protrusions on both sides thereof so that the stay can be both left and right handed. The holes, grooves, slots or protrusions are preferably situated towards the end of the arm away from its pivotted end.
The clip means is preferably of one piece construction having at one end a part fastenable to the window frame by say screws and at the other end a lip that engages said hole groove, slot or protrusions of the stay arm. The lip may be on an arm extending from said fastenable part.
Reliance is placed on the resilience or springiness of the stay to effect engagement and disengagement of the arm by the clip means. Preferably engagement or disengagement is effected by horizontal movement of the arm.
The clip means can be made of plastics, aluminium or any other suitable material.
This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a side view of a casement window stay with the window closed;
Figure 2 is a plan view of the casement window stay with the window closed;
Figure 3 is an enlarged section showing the clip means;
Figure 4 is a section showing an alternative clip means/stay arm embodiment; and
Figure 5 is a section showing yet another clip means/stay arm embodiment.
Referring to Figures 1 to 3, a casement window has a frame 10 that fits a surround 12 when closed as shown. Attached to the frame 10 is a bracket 14 that has a pivot 16 therethrough. The pivot 16 has in turn a hinge pin 17 passing through it and one end of an arm 18. The pivot 16 and hinge pin 17 permit movement of the arm both upwards and downwards and towards and away from the casement window.
The arm 18 is of an inverted U-shaped section and locates on peg 20 that is fixed to the surround 12. The arm 18 can be located on the peg 20 at any desired position along the arm depending on whether the window is to be closed or open to any desired extent.
Further along the frame 10 is a clip 24 that has an attachment plate 25 and extending horizontally therefrom an L-shaped arm 26, the other end of the arm 26 ending in a lip 27. The lip 27 is shown engaging a slot 30 in the side of the stay arm 18.
The arm 18 has, in fact, a slot 30 on each side so that the stay can be fitted as either left or righthandedly.
To release the arm 18 from the position shown, the arm is moved horizontally to disengage the lip 27 from the slot 30 whereupon the arm 18 can be raised.
Turning to Figures 4 and 5, the construction of the stay is largely the same as in the embodiment of Figures 1 to 3 and like parts have been given the same reference numerals for simplicity. The main difference in Figure 4, is however, the means of engagement between the clip 24 and the arm 18.
The arm has a rib 40 on each outer side thereof and the clip 24 has a longer L-shaped arm so that its lip 27 can engage the rib 40 on the side of the arm 18 away from the window. Again ribs 40 are provided on both sides of the arm 18 so that the stay can be fitted either right or left-handedly.
Finally in Figure 5 the clip 24 engages on the inside of the arm 18 as in Figure 1 to 3 except that the lip 27 engages a rib 45 on the inside of the arm rather than a slot. Again two ribs 45 are provided on opposite sides for left and right handed fitting options.
Engagement and disengagement of the clips of
Figures 4 and 5 is basically the same as for Figures 1 to 3.
1. A casement window stay comprising a pivotable stay arm attached to the window frame and one or more pegs on the casement surround and on which the stay arm can be located, the stay including clip means that is engageable with the stay arm when the window is closed, the clip means being on the window frame.
2. A casement window stay as claimed in claim

Claims (9)
1. A casement window stay comprising a pivotable stay arm attached to the window frame and one or more pegs on the casement surround and on which the stay arm can be located, the stay including clip means that is engageable with the stay arm when the window is closed, the clip means being on the window frame.
2. A casement window stay as claimed in claim 1, wherein the clip means engages a hole, slot, groove or protrusion of the stay arm.
3. A casement window stay as claimed in claim 2, wherein the stay arm has such a hole, slot, groove or protrusion on both sides thereof.
4. A casement window stay as claimed in claim 2 or 3, wherein the holes, slots, grooves or protrusions are situated towards the end of the stay arm away from its pivotted end.
5. A casement window stay as claimed in any one of claims 1 to 4 wherein the clip means is of one piece construction and has at one end a part fastenable to the window frame and at the other end a tip that engages said hole groove, slot or protrusion of the stay arm.
