A glass blind structure for a window with a sloping top

The invention relates to a pleated blind structure for a window 5 comprising an oblique upper edge, comprising an obliquely oriented upper rod and a movable lower rod fixedly fixed in the window and a zigzag pleated blind material therebetween, the upper pleat being attached to the upper rod and the lower pleat being fixed to the pliers; passing through at least two rows of holes in the blind material and the lower and upper bars so as to extend beyond one end of the upper bar with the blind material cut so that when the blind covers a window with the lower bar in an approximately horizontal position, the free edge of the blind material forms approximately straight a line in the vertical direction of one of said rows of holes being approximately parallel to and close to the straight, free edge of the blind material.

Such a structure is known from U.S. Pat. No. 4,518,025 and is intended for a trapezoidal window. When using traction wires, the horizontal lower bar first moves upwards in a horizontal position and then pivots against the upper bar, whereby the blind material 25 is folded.

Such a structure is also suitable for a rectangular triangular window. In this case, the two perpendicular sides of the triangle are oriented horizontally and vertically, respectively, and the second base angle of the triangle may vary in size, in which case it may be, for example, 45 ° or less or, for example, 60 °.

Such triangular windows are widely used at the ends of residential and other buildings, but often also in sun canopies, so these windows 35 are constantly in need of additional sunshades that can be attached to conventional rectangular sunshades if such a triangular window forms an extension of the rectangular window below it. .

In the known blind construction, three separate pull wires are used in the same way as in the construction for a rectangular window, as can be seen from NL patent publication 167 220 of the author of the present invention.

In a trapezoidal or rectangular triangular window, the separate tension-10 wires of the pleated blind structure always move a different length, so they cannot be used as a single unit.

It is an object of the present invention to improve this already known structure in this respect so that it is more suitable for a triangular window.

According to the invention, this is achieved by the lower bar being articulated at one end to the other end of the upper bar and the traction wires being threaded as at least one closed loop through said row of holes parallel to the vertical edge of the blind material and through at least one row of holes being at the center of the circle.

Due to the articulation of the bars, the lower bar can be turned downwards to the horizontal lower edge 25 of the triangular window.

Since the articulated end of the lower bar moves a shorter distance from the lower bar than its other end, a length compensating device must be provided on the drawbars.

In any case, the traction wires must pass through the holes 30 which are in a vertical line close to the vertical edge of the blind, thus preventing the blind material from descending when the blind is pulled up.

When the blind is pulled up, the lower bar, which is then in close contact with the upper bar, does not restrict a certain part of the blind material.

I! 3,82529

In the same way as in the already known rectangular blind structures, also in the triangular structure the blind material can consist of one or more rectangular sheets with holes at both ends in a straight line through which the tension wires pass. In this case, an additional sheet is preferably used for the blind material, which has a row of holes at both ends and which overlaps loosely at one end to the end of the rectangular sheet 10 farther from the pivot point and forms a straight, free edge when the blind is pulled down

The invention will now be described in more detail by means of several exemplary structures, in which Figure 1 shows a triangular pleated blind with a single sheet of blind material, Figure 2 shows a triangular pleated blind with a blind material comprising one rectangular sheet and one approximately triangular pleated blind, with two overlapping rectangular sheets and one approximately triangular sheet with a closed wire loop, Fig. 4 otherwise corresponds to Fig. 3, but the blind 25 now has two closed wire loops, Fig. 5 shows a pleated blind with three overlapping rectangular sheets and one shaped sheet with one closed wire loop, Fig. 6 otherwise corresponds to Fig. 5, but the pleated blind now has two closed wire loops, Fig. 7 shows the pleated blind according to Figs. there are two closed yarn loops and one open yarn, 35 Fig. 8 shows a pleated blind with four 4,82529 overlapping rectangular sheets and one approximately triangular sheet with one closed wire loop, Fig. 9 otherwise corresponds to Fig. 8, but the pleated blind has now two closed wire loops, Fig. 10 otherwise corresponds to Figs. 8 and 9, but the laser blind now has three closed wire loops, and Fig. 11 shows a leveling device for several loops.

The triangular pleated blind according to the invention comprises a conventional upper rod 1, a conventional lower rod 2 and one or more sheets of blind material, which are generally made of sun-protective material and pleated in a zigzag shape.

15 The structure further comprises, as a shutter drive, one or more pull wires coming in / out from the other end of the upper bar. All this corresponds exactly to the structure according to NL patent 167,220.

The upper bar 1 is attached to the upper edge of the window (not shown) and the lower bar 2 can be lowered or pulled up.

The triangular window with sunshade is a rectangular triangle with a horizontal and vertical edge and a sloping top edge.

The blind shown in Figure 1 can be used for such a window, provided that the horizontal width of the window is not too large.

A certain maximum width, usually 1500 mm, must be taken into account when manufacturing and folding the blind material. This width is then cut into standard widths of 410, 450, 480, 30 510 and 580 mm.

* The blind is made of several sheets of the same width, which overlap at their ends loose. The overlap points have holes through which the pull wires go.

• This is also known from NL patent 167 220.

According to the invention, the lower bar 2 is articulated at one end to the corresponding end of the upper bar 1. This articulation structure li 5 82529 can act directly on the upper and lower bar, but it can also be made as a short wire or similar part passing through the openings in a single row in the upper bar 1, the blind material 3 and the lower bar 2, and 5 having limiter.

The structure shown in Figure 1 has two rows of holes. The second line is marked with reference number 5 and the second with reference number 6.

The left edge of the sheet 3 is straight, and this row of holes 5 is a straight line when the upper bar 1 and the lower bar are parallel.

The right edge is cut so that it is straight and oriented vertically in the position shown in Fig. 1.

The row of holes 6 is therefore parallel to and located close to the right edge of the blind. It is clear that this structure can also be used as a mirror image.

The tension wire A formed as a closed loop 20 passes through the upper bar 1, down through the row of holes 5, through the lower bar 2 to the right and then back up and out through the row of holes 6 ·

Loop A can move quite freely through both the rods and the blind material.

25 When the loop A is tightened, the lower bar 2 turns towards the upper bar 1 and folds the blind 3 into size.

The blind shown in Fig. 3 can also be made in two parts, see Fig. 2. The first and larger parts are then formed by a rectangular sheet 3a, the ends of which have respective rows of holes 5 and 7, the row 5 being used for the turning wire 4.

The second and smaller part is formed by a more or less triangular sheet 3 'with a row of holes 6.

35 Sheet 3a and sheet 3 'have a row of holes 7 which overlap.

The wire loop A is then fed through the rows of holes 6 and 7 and fastened to the stop part of the lower bar 2.

The structure according to Figures 3 and 4 comprises two rectangular sheets 3a and 3b and a more or less triangular part 3 '.

The left sheet 3a has a row of holes for the turning thread 4 on the left and a row of holes 8 in addition, and a row of holes 9 on the right side, the holes of which overlap with the holes on the left side of the sheet 3b. At the knee end of the sheet 3b oi-10 there are a row of holes 7, some of which overlap more or less in the holes 6 of the triangular sheet 3 '.

In the structure according to Figure 3, one wire loop A is used, which comes down through row 6, through lower bar 2 15 completely to the left and up through row 8, through upper bar 1 to the right, down through row 9, through lower bar 2 to the right, up through row 7 and out through the upper bar 1.

In the blind according to Figure 4, two loops A and B are used, which is therefore recommended.

: 20 Loop A goes down through row 6, through rod 2 all the way to the left, up through row 8 and through rod 1 to the right and out.

Loop B goes down through line 7, through bar 2 to the left, up through line 9 and out through bar 1. Sil-25 mugs A and B are connected by a wire D which is threaded over a freely rotating roller 12 in a holder 13 with which a blind can be used (see Fig. 11). In this way, the differences between the lengths of the trajectories of loops A and B are smoothed out.

The structure shown in Figures 5, 6 and 7 uses three rectangular sheets 3a, 3b and 3c and one more or less triangular sheet 3 '.

One is used in the blind shown in Figure 5. wire loop A, which goes down through row 6, to the left • 35 in the lower bar 2, up through the row 9, through the upper bar 1 to the left! 7 82529, down through line 8, through lower bar 2 to the right, up through line 7 and out through upper bar 1.

The blind in Figure 6 uses two wire loops A and B.

5 The wire loop A goes down through row 6, to the left through the lower bar 2, up through the row 8 and through the upper bar 1 to the right and out.

The wire loop B goes down through row 7, through rod 2 to the left, up through row 9 and through rod 1 to the right-out. The leveling device according to Fig. 11 is also used in this structure.

The blind in Figure 7 uses two wire loops A and B and wire C.

Sheet 3a has an additional row of holes 10.

15 The wire loop A goes down through row 6 and through rod 2 to the left, up through row 10 and through rod 1 to the right and out.

Wire loop B goes down through row 7, through rod 2 to the left, up through row 8, and through rod 1 to oi-20 to the chin and out.

The wire C, which is not closed in a loop, passes through the upper bar 1 to the left, down through the row 9 and through the lower bar 2 to the right, where it is attached to the right-hand stop part.

25 Also in this structure, loops A and B are connected by wire D, while wire C is connected to one of loops A and B.

In the structure shown in Figures 8, 9 and 10, four rectangular sheets 3a, 3b, 3c and 3d and one approximately triangular sheet 3 'are used.

In the structure according to Fig. 8, one wire loop A is used, which passes through the row 6, through the rod 2. left to right, up through line 8, through bar 1 to the right, down through line 9, through bar 2 to the right, up: 35 through line 10, through bar 1 to the right, down through line 11, through bar 2 to the right and up through line 7 .

β 82529

In the structure according to Figure 9, loops A and B are used.

Loop A goes down through row 6, through rod 2 completely to the left, up through row 8 and through rod 1 to the right.

Loop B goes down through line 7, through bar 2 to the left, up through line 10, through bar 1 to the left, down through line 9, through bar 2 to the right, up through line 11, and through bar 1 to the right.

10 The lengths of the trajectories of loops A and B are now smoothed with the device according to Fig. 11.

The structure shown in Figure 10 uses three loops.

Loop A goes down through line 6, through bar 2 to the left, up through line 8 and through bar 1 to the right.

Loop B goes down through row 7, through rod 2 to the left, up through row 9 and through rod 1 to the right.

Loop C goes down through line 11, through bar 2 to the left, up through line 10 and through bar 1 to the right.

20 If sheets 3a-3d are of the same width, loops B

· '· And C the length of the trajectories is then the same.

. : They can then be connected to one end of the leveling wire D, while loop A is connected to the other end of the wire D.

25 The width of the blind structure can be increased by using several rectangular sheets.

The wire feed system then remains essentially the same.

At the same time, the number of yarn loops depends on the number of sheets 30. Extra yarn can be used.

: * If there are an even number of rows of holes, you can always! * Only use wire loops.

If there are an odd number of rows of holes, extra thread is also needed.

: 35 The wire loops always move relative to both the bars and the sheets of blind material.

Il β 82529

The extra thread is always attached to one end of the lower bar.

The wire loops and possibly also the wire are operated simultaneously with the same lever and are connected 5 or not connected to each other by the smoothing device according to Fig. 11.
