[0001] This invention relates to a window comprising a main frame and a sash pivotally journalled therein, with a blind mounted internally of the sash, which blind is formed from horizontally extending slats and has an adjusting mechanism provided with an operating member accessible from the internal side of the sash, the window further comprising an insect screen adapted to be detachably mounted in the main frame internally of the window sash with the blind between the screen and the sash.
[0002] US-A-2 311 300 discloses a window of almost the same type except that the insect screen is mounted externally of the window sash, i.e. between the sash and the blind, and is intended to be held permanently in place. This follows from the fact that parts of the mechanism for adjusting the blind are supported by the screen and cannot easiy be separated from the parts of the mechanism belonging to the blind. Only the operating crank of the mechanism may be detached or removed, as shown in Fig. 6 of the document, butthis feature serves only the purpose of allowing the sash to be closed from its open position.
[0003] In known windows of the type specified above it is a drawback that the insect screen in its mounted position internally of the window sash impedes the access to the knob on the inner face of the sash and the operation of said knob thus necessitates the screen to be temporarily taken down. This does not only cause some extra trouble, but it also involves the risk of insects flying in atthe window if not completely closed.
[0004] Said drawback is eliminated through the invention in that the insect screen carries a further operating member, e.g. a knob, and a flexible element is provided for connecting the two operating members which element has a head portion engageable in a non-circular socket of the first said operating member so as to be slidale but non-rotatable relative thereto. Each operating member may take the form of a knob.
[0005] In this case the slat blind adjusting mechanism may, owing to the additional operating member, e.g. additional knob, be operated while the insect screen is in its position of use, but a far more decisive advantage is, however, that the clutch connection between said two knobs is automatically established when mounting the screen, as the head on the flexible shaft will then so to say by itself find its way into the non-circular socket. Neither when mounting the insect screen nor when demounting it does the clutch mechanism require any attention from user's position.
[0006] In order to prevent the head from getting jammed upon displacement in the socket, said head may advantageously be approximately spherical with incisions for slidable engagement with inwardly projecting cams in the socket. The spherical shape allows for a certain angular movement of the flexible shaft which may then without any harm have an appropriate longitudinal stiffness, and the incisions and the cams may for example give the head and the socket a hexagonal cross-sectional view.
[0007] In order to ensure sufficient stability it is preferred to journal the knob of the insect screen in a pair of fixture plates located on either side of the screen, one of which being fixableto an edge rail of the screen. This further eliminates the risk of damaging the screen proper, for instance when handling it roughly either manually or by motor operation.
[0008] An embodiment of the invention is illustrated on the drawing showing a sectional view of the upper part of a window, which may for instance be of the tilting type.
[0009] In the drawing 1 is the top member of the main frame of the window in which a sash 2 is mounted in an ordinary way. Inside a double-glass pane 3 the sash 2 carries an ordinary slat blind 4 having a mechanism, not shown in detail, for adjustment of the inclination of the slat blind lamellas 5. Said mechanism includes a knob 6 secured on a bushing 7 having an elongate, socket 8 of non-circular cross-section.
[0010] Inside the sash 2 the main frame 1 supports a detachable insect screen 9 in the moulding 10 which when mounted is secured in a recess provided in the main frame. Said screen comprises further a knob 11 journalled in a pair of fixture plates 12 on either side of the screen 9 proper, at least one of which for stability purposes being in engagement with the moulding 10. The knob 11 is firmly connected with a flexible shaft 13 extending into the socket 8 in the bushing 7 of the first mentioned knob 6 and having at its foremost end an approximately spherical head 14 which has a non-circular cross-section similar to that of the socket 8.
1. A window comprising a main frame (1) and a sash (2) pivotally journalled therein,with
a blind (4, 5) mounted internally of the sash, which blind is formed from horizontally
extending slats and has an adjusting mechanism provided with an operating member (6)
accessible from the internal side of the sash, the window further comprising an insect
screen (9, 10) adapted to be detachably mounted in the main frame internally of the
window sash with the blind between the screen and the sash, characterised in that
the insect screen (9, 10) carries a further operating member (11) and a flexible element
(13) is provided for connecting the two operating members which element has a head
portion (14) engageable in a non-circular socket (8) of the first said operating member
(6) so as to be slidable but non-rotatable relative thereto.
2. A window according to claim 1 wherein said head portion (14) is shaped to engage
splines carried by the first said operating member.
3. A window according to claim 1 or claim 2 wherein said head (14) of the flexible
element (13) is approximately spherical with incisions for sliding engagement with

member (11) carried by the insect screen (9, 10) is journalled in a pair of fixture
plates (12) located on either side of the screen, one of which being fixable to an
edge rail (10) of the screen (9).
