Definitions
- a window screening device A window screening device
- the invention relates to a window screening device, particularly for a skylight or a similar permanent or temporary oblique window, comprising a screening element, particularly of pleated material, fastened between a top casing firmly attached to a top member of the window sash and a slidable bottom beam as well as guidance means, comprising a cord arrangement with guidance cords, which are individually routed from the top casing through one of at least two rows of openings in the screening element and further through the bottom beam and a side guide strip for the screening element to one end of a bottom member of the window sash and from there back to the top casing, each guidance cord being connected in the top casing with one end of a tension spring the other end of which is fastened to a stationary point in the top casing.
- a window screening device of this kind is known from EP patent No. 015 043.
- the purpose of the cord arrangement is to ensure parallelism between the top casing and the bottom beam when the screening element is parked in different positions in the window opening and to the extent possible also to ensure parallel guiding during operation of the screening element, which is performed using a handle placed in the middle of the bottom beam.
- the bottom beam By attempting to pull the bottom beam by one of its ends near a side guide, the bottom beam will, however, be pulled askew, as the spring-loaded cord control in the opposite end of the bottom beam, as a result of friction at the positions where the cord changes direction, prevents the bottom beam from moving and so to speak locks the concerned end of the bottom beam.
- the application of sufficiently tight springs could be considered, which at skew load will make the cord tension of the cord control at the opposite side almost momentarily constant, even though the bottom beam is affected by a tug in one end.
- Such solution has, however, turned out to be accompanied by unacceptable wear and tear of cords and cord routings, which normally consist of plastic bushes, or by a friction at bush routings and other places where a cord changes direction which is so high that the operating comfort is considerably reduced.
- the invention provides the possibility of using an operating handle extending the entire width of the bottom beam.
- the invention furthermore has the advantage that mounting of the guidance cord arrangement does not require intervention in the sash bottom member, which to a considerable extent eases after-mounting.
- fig. 1 shows a skylight with a window screening device in the form of a folding blind and fig. 2 a guidance cord arrangement in an embodiment of the window screening device according to the in ⁇ vention.
- FIG 1 a skylight of by it self con ⁇ ventional type having a window sash comprising at top member 1 and a bottom member 2 as well as two side members 3 and 4.
- the sash top member 1 is in a known manner, not shown, provided with closure fittings for the window, which is operated by means of an operating handle 5 extending the entire width of the window, which operating handle is fastened to a pivotable flap 6, covering a ventilation opening formed in the sash top member 1 for providing ventilation in the closed position of the window.
- the window is provided with a window screening device according to the invention, in the example shown a folding blind with a blind element of pleated material.
- the blind element 7 is mounted between a top casing 8, which is firmly connected to the sash top member 1, and a bottom beam 9, which can be brought up and down in the window opening for blinding or screening of a large or small part thereof.
- the folding blind 7 is adapted to manual hoisting and lowering by means of an operating handle 10 fastened to the bottom beam 9, which operating handle, like the operating handle 5, extends substantially the entire width of the window.
- the hoisting and lowering can be carried out by means of a cord control, not shown, which in a known way can be performed in such a way that the bottom beam 9 can be parked in any intermediate position between a fully hoisted position of the blind 7, the bottom beam 9 being placed immediately below the top casing 8, and a completely drawn position, the bottom beam 9 coming into contact with the sash bottom member 2.
- the blind 7 can in a manner known per se be adapted to motorized operation instead of manual operation.
- the window screening device is provided with a guidance cord arrangement with a number of guidance cords, of which figure 1 shows four cords which are routed through rows of openings provided in the individual folds of the pleated material in the blind element 7.
- Figure 2 shows the window screening device accord ⁇ ing to the invention in a fully hoisted position, the folding blind element 7 being completely folded and the bottom beam 9 being placed close to the top casing 8.
- the guidance cord arrangement comprises two pieces of cord, which in the example shown - with a relatively wide window, where four rows of openings are provided in the blind element 7, said rows of openings being placed symmetrically around a vertical central axis in the blind element - are routed through their respective row of openings in both sides of the blind element 7.
- the fully pulled up guidance cord 11, starting from the top casing, is routed through the outermost right row of openings 13 of the blind element 7 and from there through the bottom beam 9 to the opposite left side thereof, from where it is routed hidden in a side guide strip 14 fastened to the sash side member 3 - see fig. 1 - to a junction 15 with the sash bottom member 2 in the left side thereof.
- the cord piece 11 is from there routed back through the same side guide strip 14 and the bottom beam 9 and up through the row of openings 19 in the blind 7.
- the other cord piece 12 shown by a thin line, is routed from the top casing 8 through the innermost row of openings 18 in the left side of the blind element 7 and the bottom beam 9 to a junction 17 on the sash bottom member 2 in the right side and back through the bottom beam to the outermost row of openings 20 in the left side of the blind element 7.
- each of the cord pieces 11 and 12 is connected with one end of a tension spring 21 and 22, respectively, the other end of which is fixed to a point in the top casing.
- the special features of the guidance cord arrangement are that for each of the tension springs 21 and 22 in the top casing 8 there is a stopping device 23 and 24, respectively, for limiting the travelling of the spring, and that the free ends of the cord pieces 11 and 12 in each side of the top casing 8 are joined in a freely slidable or flowing junction 25 and 26, respectively, which can be provided either as an ordinary knot or by means of a specially designed joint clip.
- the two tension springs 21 and 22 are fastened in a joint spring holder 27, which is fastened approximately in the middle of the top casing 8 and is provided with end portions forming said stopping devices 23 and 24.
- cord routing bushes are fastened, which together with the stopping devices 23 and 24 limit the possibility of moving the slidable or flowing junction 25 and 26, respectively, between the ends of the cord pieces 11 and 12.
- the screening element e.g. for a narrow window
- the screening element can be provided with only two rows of openings instead of four.
- the two guidance cords are thereby routed through the same row of openings in each side of the screening element.
