Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes an upper bar that is fixedly attached to an inclined upper window edge and extends obliquely, and a movable lower bar, wherein the upper bar and the lower bar are connected to each other. with the screen material folded in a zigzag shape between, the topmost fold attached to the upper bar;
a lowermost fold is attached to the lower bar and extends from one end of the upper bar outwardly thereof through at least two rows of apertures provided in the screen material and the upper and lower bars; In the shielded position of a curtain screen structure with extending tension cords and lower bars running substantially parallel, said screen material is cut so that its free border is a substantially straight, vertical line segment. a window fold with a sloped upper edge, one row of the plurality of openings being substantially parallel to and proximate to the linear free border of the screen material; This relates to a type scree curtain.

Such a structure is disclosed in US Pat. No. 4,518,025 for trapezoidal windows. Regarding the operation of the tension cord, the horizontal lower bar is
It first moves parallel and upward and then pivots relative to the upper bar, thereby folding the screen material.

Also, such a structure is suitable for windows in the shape of a right triangle. The two sides at right angles to each other extend horizontally and vertically, and the other reference angles can be of various values, for example 45° or less, or
It has an angle of 60°.

Such triangular windows are often installed in gables in houses, other buildings and sun lounges, and if the triangular window forms an extension of a rectangular window located below it. , the need for triangular window shades, which must be adjacent to a suitable rectangular shade, is constantly increasing.

In the known curtain construction, as disclosed in Dutch Patent No. 167220, three separate cords are used in the same way as they are used in rectangular window structures.

In trapezoidal windows, i.e. windows with right triangles in them, the separation cords move over different distances when the structure is opened and closed, and therefore the cords cannot be operated as a single unit.

The object of the invention is to improve the known construction with respect to the above-mentioned drawbacks and to adapt the known construction to triangular windows.

To achieve the above object, in accordance with the present invention, the lower bar is pivotally connected at one end to one end of the upper bar;
The tension cords pass through the rows through the openings parallel to the vertical boundaries of the screen material in the form of at least one closed loop and in a circular arc about the pivot point in the shielded position of the curtain screen structure. It is characterized in that it is threaded through at least one of the plurality of rows of openings arranged in parallel.

As a result of the pivoting between the two bars, the lower bar can be pivoted downwards towards the horizontal base of the triangular window.

Since one pivoted end of the lower bar moves less than the other end of the lower bar with respect to the upper bar, compensation of the length of the tension cord is necessary.

In any case, the tension cord extends through a plurality of apertures in the vicinity of a vertical straight border extending on a vertical straight line, which means that the shade is pulled up. This prevents the screen material from sagging in certain positions.

In the pulled-up position, the parts of the screen material are not restricted by the lower bar making a closing contact with the upper bar.

In the case of known rectangular curtain screen constructions, the screen material consists of one or more rectangular sheets having a plurality of straight line openings at each end through which tension cords extend. There is something set up.

In a preferred embodiment, said scree material is provided with a sheet material separate from said rectangular sheet, said sheet material being provided with a row of openings at each end thereof, and said sheet material further comprising: At one end,
It loosely overlaps the ends of the rectangular sheets facing away from the pivot point and forms a free straight boundary in the shielded position of this structure, where the lower bar is substantially horizontal.

Embodiments according to the present invention will be described in detail below based on the drawings.

The triangular pleat according to the present invention is composed of a known upper bar 1, a known lower bar 2, and one or more sheets of screen material;
This sheet is generally made of a light-blocking material and folded into a zigzag shape.

Furthermore, there are one or more tension cords, which emerge outwardly at one end of the upper bar 1 for manipulation. This means that Dutch patent no.
It fully corresponds to the configuration related to No. 167220.

The upper bar 1 is fixed along the upper edge of the window (not shown), while the lower bar 2 can be moved up and down. The triangular window, which must be provided with a light shield, has the shape of a right triangle with horizontal and vertical borders and a sloped upper edge.

The screen in FIG. 1 is used for windows whose horizontal width is not very large. In manufacturing and pleating the screen material, the maximum width is generally
There is a limit of 1500mm. Said width is 410, 450,
Cut to standard widths of 480, 510, and 580mm. In practice, the screen consists of several sheets of the same width, loosely overlapping each other at the ends. In the overlapping portion there are a plurality of openings through which the tension cord extends. This is known from Dutch patent no. 167220.

Regarding the invention, the lower bar 2 is connected to the upper bar 1 at one end.
are pivotally connected to the corresponding ends of. This pivot joint acts directly on the upper and lower bars and is formed by one short cord 4 which is aligned in the upper bar 1, the screen material 3 and the lower bar 2. and has a stop member at each end.

With reference to FIG. 1, two rows of openings are further provided. The first column is designated by 5 and the second column by 6. The boundary line of the sheet 3 on the left hand side in the drawing is linear, and if the upper bar 1 and the lower bar 2 are made parallel, the row of openings 5 will be linear. The border line on the right-hand side of the drawing of sheet 3 is cut straight and vertically at the position shown in FIG. The rows of openings 6 thus run parallel near the boundary line on the right-hand side of the drawing. It is clear that the above structure can be used in mirror image form with respect to FIG.

The tension cord A in the form of a closed loop passes through the upper bar 1, downwardly through the row of openings 5, through the lower bar 2 to the right, and back up through the row of openings 6 and out. Run. The looped cord A can therefore move freely through the upper and lower bars and through the screen material.
When the looped cord A is pulled, the lower bar 2
moves pivotally towards the upper bar 1 and folds together the scree material 3.

The screen material 3 in FIG. 1 is composed of two parts as shown in FIG. The first, larger part is formed by a rectangular sheet 3a having a row of a plurality of openings 5, 7 with holes at both ends, said row of openings 5 being for the pivoting cord 4. used. The second, smaller part is formed by a generally triangular sheet 3' with a plurality of rows of openings 6. The sheets 3a and 3' have a plurality of rows of openings 7 overlapping each other. The looped cord A is then fed through the row of openings 6, 7 and secured to the end stop of the lower bar 2.

The structure shown in FIGS. 3 and 4 consists of two rectangular sheets 3a and 3b and a substantially triangular sheet 3'. The sheet 3a on the left hand side of the drawing is the pivot code 4
a plurality of rows of openings 8 for the seat 3 on the left-hand side;
The right hand side has a plurality of rows of openings 9 overlapping with the left hand side of b. The seat 3b has on its right hand side a row of openings 7 which again overlap the openings 6 of the approximately triangular shaped seat 3'.

In the third, a single looped cord A is used, which looped cord A goes down through the opening 6, almost to the left through the lower bar 2, and up through the opening 8. to the right through the upper bar 1, down through the opening 9, to the right through the lower bar 2, up through the opening 7 and to the upper bar 1.
running outside through.

In Figure 4, two loop-shaped cords A and B
is suitably used. The looped cord A goes downwards through the opening 6, almost to the left through the lower bar 2, upwards through the opening 8, to the right through the upper bar 1 and out. Looped cord B

Go outside through. As shown in FIG. 11, loop-shaped cords A and B are connected by cord D,
This cord D is screwed above a freely rotating pulley or roller 12 into a holder 13 which is capable of manipulating the screen material. In this way, the compensating section that moves the loop-shaped cords A and B produces a differential at a distance.

In the configurations shown in Figures 5, 6 and 7, three rectangular sheets 3a, 3b, 3c and a substantially triangular sheet 3' are used.

In FIG. 5, one looped cord A is used, which looped cord A goes down through the opening 6, to the left in the lower bar 2, up through the opening 9, to the upper side. bar 1 to the left and down through opening 8;
To the right through the lower bar 2, up through the opening 7 and out through the upper bar 1.

In Figure 6, two loop-shaped cords A and B
is used. The looped cord A runs down through the opening 6, to the left through the lower bar 2, up through the opening 8, to the right through the upper bar 1 and out. The looped cord B runs down through the opening 7, to the left through the lower bar 2, up through the opening 9, to the right through the upper bar 1 and out. Here again, the compensation means shown in FIG. 11 is used.

In FIG. 7, looped cords A and B and cord C are used. The sheet 3a further has a plurality of rows of openings 10. The looped cord A runs down through the opening 6, to the left through the lower bar 2, up through the opening 10, to the right through the upper bar 1 and out. Looped cord B
runs down through the opening 7, to the left through the lower bar 2, up through the opening 8, to the right through the upper bar 1 and out. The cord C, which is not closed so as to form a loop, runs to the left through the upper bar 1, down through the opening 9, to the right through the lower bar 2, and at the right-hand end. It is fixed to the stop. Here again, two looped cords A
and B are linked by a cord D, and the cord C is connected to either one of the looped cords A and B.

In the embodiments of Figures 8, 9 and 10, four rectangular sheets 3a, 3b, 3c and 3d and a substantially triangular sheet 3' are used.

In the embodiment of FIG. 8, one looped cord A is used, which looped cord A goes downwards through the opening 6, almost to the left through the lower bar 2, and through the opening 8. to the right through the upper bar 1; down through the opening 9; to the right through the lower bar 2; up through the opening 10;
through the opening 11 to the right, through the opening 11 to the right, through the lower bar 2 to the right and through the opening 7 up.

In the embodiment of FIG. 9, looped cords A and B are used, looped cord A being connected to the opening 6.
Go down through the lower bars, almost to the left through the two lower bars, up through the eight openings, and to the right through the upper bar one. The looped cord B goes down through the opening 7 and to the left through the lower bar 2 through the opening 10.
up through the upper bar 1, to the left through the upper bar 1, down through the opening 9, to the right through the lower bar 2, up through the opening 11, and to the left through the upper bar 1. Go to the right. The movement course of the loop-shaped cords A and B is again compensated by the device according to FIG.

In the embodiment of FIG. 10, three looped cords are used. The looped cord A goes downward through the opening 6, to the left through the lower bar 2,
Go up through the opening 8 and to the right through the upper bar 1. The looped cord B goes down through the opening 7, to the left through the lower bar 2, up through the opening 9 and to the right through the upper bar 1.
The looped cord C passes downward through the opening 11,
Go to the left through the lower bar 2, up through the opening 10 and to the right through the upper bar 1.

If the sheets 3a to 3d have the same width,
Looped cords B and C move the same distance. The looped cords B and C are thus connected together to one end of the compensating cord D, while the looped cord A is connected to the other end of said cord D.

The width of the curtain structure can be increased by adding more rectangular sheets. The code supply system is fundamentally the same. At the same time, the number of looped cords depends on the number of sheets. Additional codes may be used. If the number of rows of openings through which the looped cords pass is even, a plurality of looped cords can be used at any given time. Furthermore, if the number of rows of openings through which the looped cord passes is odd, additional cords will be required.

The looped cord moves relative to the two bars and relative to the sheet of screen material. The additional cord is always attached to one end of the lower bar.

A plurality of loop cords or a single cord are operated simultaneously in the same operation, and are connected to or disconnected from each other through the compensation means shown in FIG.
