Definitions
- This invention refers to a folding blind extending between a first beam and a second beam in parallel relationship thereto, guiding cords being in frictional engagement with said pair of first and second beams and tensioned therebetween, guiding said beams between positions of relative displacement, and panel means of pleated material to blind a variable area along the path of said beams.
- Folding blinds of the above kind are known in various embodiments, forms and patterns, the folding blind usually serving as a sunshade on a window, as for instance disclosed in US-A-4202395.
- the beams can be slid up or down along the cords, the pleats folding in or out like a concertina.
- the invention has for its aim to ameliorate the folding blind giving the user increased possibilities to arbitrarily cover to a greater or lesser extent the opening to be screened by the blind, so covering the top, bottom or an intermediate part of that opening.
- the folding blind according to the invention is distinguished in that additional top and bottom beams forming part of the blind are fixed relative to each other and parallel to the first and second beams to define a space of fixed area therebetween, said pleated panel means being connected either to the top and first beam and the bottom and second beam respectively, or between the first and second beam; the cords being accomodated in and running inside the first, the second, the top and the bottom beams and through aligned apertures in the pleated panel means.
- the invention provides a composite folding blind comprising more than one folding blind of the type described above linked one to the other, whereby it is possible to select various patterns of pleated material using still existing elements.
- a coupling strip is employed therewith coupling the beam of one blind to the beam of the other blind.
- said coupling strip may be provided with anchoring means to forming a fixed beam between the fixed top and bottom beams.

- a panel of pleated material is fitted between the fixed top and bottom beam and the first and second intermediate beam respectively.
- the invention proposes applying in addition to the guiding cords a second cord system which is fastened to the first and second intermediate beams, whereby the two beams are movable compulsorily opposite to each other. So, when moving the lower intermediate beam upwards the upper intermediate beam will move downwards in a controlled manner.
- the invention refers to a cover strip preferably in L-section, arranged along the upright side of the folding blind and provided with a groove for the accommodation of filler strips.
- the gap between the side of the window recess and the edge of the folding blind is optically closed, while the filler strips serve to compensate the slant of the side of the recess relative to the window pane.

- Figure 1 shows a folding blind of the usual kind, consisting principally of a fixed top beam 1, a fixed bottom beam 2 and parallel slidable between them intermediate beam 3. Between fixed top beam 1 and intermediate beam 3, panel of pleated material 4 is fastened. Intermediate beam 3 is guided by means of cords 5,6, cord 5 running from the centre of top beam 1 via apertures in the pleated material through intermediate beam 3 to the sides thereof, and then along the side edges to bottom beam 2. Cord 6 runs from out of the bottom beam up along the side edge to intermediate beam 3, and then from the outer end thereof to a hole beyond the centre where the cord passes through corresponding apertures in the pleated material to the top beam and then returns through this top beam to a second off-centre hole in mirror-image fashion to bottom beam 2. The ends of cords 5,6 are fastened to a tension spring 7 for keeping the cords under tension.
- beam 3 can be moved up and down by hand, the pleats folding in or out respectively.
- Figures 3, 4 and 5 show embodiments which are improved according to the invention with respect to the embodiment of figure 1 by the fitting of a second intermediate beam 8 parallel to intermediate beam 3.

- the cord system consists here of two cords 9,10 which are reeved in mirror-symmetrical fashion, each cord running from a tensioning member 7 in the top beam to the sides therof, and then to the side of intermediate beam 8, passing through beam 8 to a non-central opening thereof, via apertures in pleated material 4 to a corresponding opening in intermediate beam 3, then returning through beam 3 to the end thereof, and from there to the end of fixed bottom beam, where it is again fastened to a tensioning member 7.
- cord 9 with an extra cord which, via an extra opening in intermediate beams 3,8 and pleated material 4, can function as an extra guide for this panel of material.
- FIG. 4 shows in detail that the beams - fixed beams 1,2 as well as movable beams 3,8 - all have the same cross-sectional form.
- This sectional form consists princi pally of a rectangular box-sectional strip 11, on a long rectangular side of which two angle-section strips 12 are fitted.
- the flanges of the angle-sections point outwards, each forming a longitudinal groove 13.
- the sectional strips are closed at the ends by end blocks 14 which also function to guide cords 9 and 10.
- box-section 11 of movable beams 3,8 is fastened to an end strip 15 of pleated material 4.
- the special shape of the beam is not only relatively rigid so that large stresses are possible while the dimensions are nonetheless small, but additionally the flanges of angle-sections 12 function for protection of cords 9,10 and accommodation of tensioning member 7, or or for coupling purposes as will be explained further below.

- This coupling is achieved through a coupling strip 20, which is further described below. With this coupling it is possible to enlarge or reduce pleated panel 24 by the sliding up or down of intermediate beam 28, the lower intermediate beam 3 of pleated panel 4 being similarly slidable up or down for reducing or enlarging pleated panel 4.
- intermediate beam 20 is secured to the side of the window recess by means of fastening means according to figure 6. It is however also possible to let composite beam 8,20,23 remain freely movable up and down.
- each cord being routed for some distance through coupling strip 20 in order to obtain the necessary sliding resistance and for obtaining the self-braking effect for holding the beam at a determinate level.
- Coupling beam 20 which can be seen in detail in figure 7, consists principally of an H-sectional strip, legs 21 of the H-section being so shaped that the upper part thereof is complementary to the outward form of the above described fixed or moveable intermediate beam.
- the height of the top part of leg 21 covers the full height of the standard sectional strip of the folding blind, whereas the bottom part of shaped leg 21 encompasses only the hook-like flanges 12 (see figure 5).
- This causes an intermediate beam 8,20,23 to be visible which displays outwardly two grooves 22, one above the other, giving the bar a slim appearance which is aesthetically pleasing.
- the bottom part of shaped leg 21 of H-section coupling strip 20 can also serve for the attachment of handgrip section 34 (see figure 7), strip 20 then being usable as a covering and/or stiffening strip for single intermediate beam 3,8 of figure 3.
- handgrip section 34 can have any arbitrary length and, owing to the small hooked ribs 35, can be snapped between the turned-over parts of shaped legs 21 at arbitrary positions.

- Movable beams 43 and 44 are guided with respect to fixed beams 41 and 42 via a cord guidance system 46 and 47, cords 46 and 47 being reeved symmetrically with respect to an imaginary mirror plane.
- the ends of both cords are fastened to a tension springs 48 in order, to maintain the cords under tension.
- Cords 46 and 47 are joined together at their bottom ends so that one cord is in fact sufficient, or both cords are knotted together, or are fastened to bottom beams 42.

Description
- This invention refers to a folding blind extending between a first beam and a second beam in parallel relationship thereto, guiding cords being in frictional engagement with said pair of first and second beams and tensioned therebetween, guiding said beams between positions of relative displacement, and panel means of pleated material to blind a variable area along the path of said beams.
- Folding blinds of the above kind are known in various embodiments, forms and patterns, the folding blind usually serving as a sunshade on a window, as for instance disclosed in US-A-4202395.
- In order to cover the window to a greater or lesser extent, the beams can be slid up or down along the cords, the pleats folding in or out like a concertina.
- The invention has for its aim to ameliorate the folding blind giving the user increased possibilities to arbitrarily cover to a greater or lesser extent the opening to be screened by the blind, so covering the top, bottom or an intermediate part of that opening.
- The folding blind according to the invention is distinguished in that additional top and bottom beams forming part of the blind are fixed relative to each other and parallel to the first and second beams to define a space of fixed area therebetween, said pleated panel means being connected either to the top and first beam and the bottom and second beam respectively, or between the first and second beam; the cords being accomodated in and running inside the first, the second, the top and the bottom beams and through aligned apertures in the pleated panel means.
- In an embodiment the invention provides a composite folding blind comprising more than one folding blind of the type described above linked one to the other, whereby it is possible to select various patterns of pleated material using still existing elements.
- Preferably a coupling strip is employed therewith coupling the beam of one blind to the beam of the other blind.
- Moreover, said coupling strip may be provided with anchoring means to forming a fixed beam between the fixed top and bottom beams.
- The coupling strip can also function as a stiffening strut to reinforce the intermediate beams against sagging, in cases of large lengths of beam or of excessive tension.
- Finally, the intermediate beam is suitable for the attachment of handles or suchlike to make the operation thereof easier.
- Since, owing to the use of the coupling strip, standard sectional strips can be utilized for the fixed and moveable beams of the folding blind, the cost can be reduces without diminishing the aesthetic appearance of the folding blind.
- In another embodiment a panel of pleated material is fitted between the fixed top and bottom beam and the first and second intermediate beam respectively. This produces in effect two folding blinds which can gradually cover the opening from below or above respectively. Moreover, it is possible to make the length of the folding blinds such that either one of them can cover the entire opening, it then being advantageous according to the invention to give each panel of material a different pattern or colour.
- For high windows, the invention proposes applying in addition to the guiding cords a second cord system which is fastened to the first and second intermediate beams, whereby the two beams are movable compulsorily opposite to each other. So, when moving the lower intermediate beam upwards the upper intermediate beam will move downwards in a controlled manner.
- Finally, the invention refers to a cover strip preferably in L-section, arranged along the upright side of the folding blind and provided with a groove for the accommodation of filler strips. In this way the gap between the side of the window recess and the edge of the folding blind is optically closed, while the filler strips serve to compensate the slant of the side of the recess relative to the window pane.
- The invention will be further explained in the description with drawings, below, of several embodiments.
- In the drawings:
- Figure 1 shows a perspective front view of a known folding blind, provided however with a cover strip along its upright side edge,
- Figure 2 shows a perspective view, corresponding to figure 1, of a detail thereof,
- Figure 3 shows a perspective front view of a folding blind according to the invention,
- Figure 4 shows a perspective front view corresponding to figure 3 of a part of the folding blind from that figure, fitted in the recess of a window,
- Figure 5 shows a view corresponding to figure 4 of a composite folding blind according to the invention, a coupling strip being employed,
- Figure 6 shows perspective views of fastening means for the coupling strip,
- Figure 7 shows a perspective view of the coupling strip as a stiffening member and equipped with a handgrip, as necessary for an intermediate beam for the folding blind of figure 3.
- Figure 8 shows a perspective view of a first embodiment in which the two folding blinds are freely movable with respect to each other.
- Figure 9 shows in a front view a folding blind corresponding to figure 1, the intermediate beams being however coupled by a cord system.
- Figure 1 shows a folding blind of the usual kind, consisting principally of a fixed top beam 1, a
fixed bottom beam 2 and parallel slidable between themintermediate beam 3. Between fixed top beam 1 andintermediate beam 3, panel of pleated material 4 is fastened.Intermediate beam 3 is guided by means ofcords 5,6, cord 5 running from the centre of top beam 1 via apertures in the pleated material throughintermediate beam 3 to the sides thereof, and then along the side edges tobottom beam 2.Cord 6 runs from out of the bottom beam up along the side edge tointermediate beam 3, and then from the outer end thereof to a hole beyond the centre where the cord passes through corresponding apertures in the pleated material to the top beam and then returns through this top beam to a second off-centre hole in mirror-image fashion tobottom beam 2. The ends ofcords 5,6 are fastened to a tension spring 7 for keeping the cords under tension. - Owing to this routing of the cords,
beam 3 can be moved up and down by hand, the pleats folding in or out respectively. - Figures 3, 4 and 5 show embodiments which are improved according to the invention with respect to the embodiment of figure 1 by the fitting of a second
intermediate beam 8 parallel tointermediate beam 3. In these figures, the corresponding elements are labelled with the same reference numbers as in figure 1. - Owing to the changed cord routing, both
intermediate beams - The cord system consists here of two
cords 9,10 which are reeved in mirror-symmetrical fashion, each cord running from a tensioning member 7 in the top beam to the sides therof, and then to the side ofintermediate beam 8, passing throughbeam 8 to a non-central opening thereof, via apertures in pleated material 4 to a corresponding opening inintermediate beam 3, then returning throughbeam 3 to the end thereof, and from there to the end of fixed bottom beam, where it is again fastened to a tensioning member 7. - It is also possible to elaborate cord 9 with an extra cord which, via an extra opening in
intermediate beams - Figure 4 shows in detail that the beams -
fixed beams 1,2 as well asmovable beams 3,8 - all have the same cross-sectional form. This sectional form consists princi pally of a rectangular box-sectional strip 11, on a long rectangular side of which two angle-section strips 12 are fitted. The flanges of the angle-sections point outwards, each forming alongitudinal groove 13. The sectional strips are closed at the ends byend blocks 14 which also function to guidecords 9 and 10. - On the side opposite angle-
sections 12, box-section 11 ofmovable beams end strip 15 of pleated material 4. - The special shape of the beam is not only relatively rigid so that large stresses are possible while the dimensions are nonetheless small, but additionally the flanges of angle-
sections 12 function for protection ofcords 9,10 and accommodation of tensioning member 7, or or for coupling purposes as will be explained further below. - Figure 5 shows an embodiment in which a composite folding blind is displayed.
- Here there are two or more panels of pleated material of identical or of different patterns fitted before a window opening. The window consists here of two panes R situated one above the other, separated from each other by a cross-beam D.
- In the embodiment according to figure 5, two panels of pleated material 4 and 24 are situated one above the other, the lower
intermediate beam 23 of panel 24 being coupled to the upperintermediate beam 8 of pleated panel 4. This coupling is achieved through acoupling strip 20, which is further described below. With this coupling it is possible to enlarge or reduce pleated panel 24 by the sliding up or down ofintermediate beam 28, the lowerintermediate beam 3 of pleated panel 4 being similarly slidable up or down for reducing or enlarging pleated panel 4. - In the embodiment shown,
intermediate beam 20 is secured to the side of the window recess by means of fastening means according to figure 6. It is however also possible to letcomposite beam - If composite
intermediate beam - If however the intermediate beam is freely suspended, a cord routing according to figure 3 is preferable, each cord being routed for some distance through
coupling strip 20 in order to obtain the necessary sliding resistance and for obtaining the self-braking effect for holding the beam at a determinate level. -
Coupling beam 20, which can be seen in detail in figure 7, consists principally of an H-sectional strip,legs 21 of the H-section being so shaped that the upper part thereof is complementary to the outward form of the above described fixed or moveable intermediate beam. The height of the top part ofleg 21 covers the full height of the standard sectional strip of the folding blind, whereas the bottom part ofshaped leg 21 encompasses only the hook-like flanges 12 (see figure 5). This causes anintermediate beam grooves 22, one above the other, giving the bar a slim appearance which is aesthetically pleasing. - The bottom part of
shaped leg 21 of H-section coupling strip 20 can also serve for the attachment of handgrip section 34 (see figure 7),strip 20 then being usable as a covering and/or stiffening strip for singleintermediate beam angle flanges 12.Handgrip section 34 can have any arbitrary length and, owing to the small hookedribs 35, can be snapped between the turned-over parts ofshaped legs 21 at arbitrary positions. - Returning to figures 1 and 2, it should be observed that between the window recess and pleated panel 4 there remains a slit-shaped gap through which light can pass. In order to close off this gap, the invention proposes fitting a principally L-section strip along the inner side of window recess R. L-
section cover strip 30 in figure 1 is shown in detail in figure 2. The one leg extends parallel to the window pane or to pleated panel 4, while the other leg extends along the inner side of recess R and also continues for the full height of fixed top andbottom bars 1,2. - Since in many cases window recess R displays a surface slanting with respect to the window-pane,
leg 31 ofsectional strip 30 which extends over that surface is made with two grooves 32 close to the long edges thereof. In a groove there can be fittedfiller strip 33, which also extends for the full height of the cover strip (see right in figure 1). In this way a close-fitting joint is obtained betweenstrip 30 and window recess R. - If required, the cover strip can also be fitted in a reversed sense along recess R, the leg parallel to the window-pane being situated in front of pleated panel 4. In this case,
filler strip 33 in groove 32 should be fitted into the groove 32 next to the corner of the L-section to allow for the slanting orientation of the inside of the window recess. - It will be clear that
cover strip 30 can also be applied to the folding blind illustrated in the other figures. - In figures 8+9 the corresponding parts are indicated by the same reference numbers, combined with the numeral 4.
- The blind according to the invention consists of a
top beam 41 and a bottom beam 42 which are assumed to be fastened in a known way to the framework of a window or opening. The fastening can take place in an arbitrary way, for example with screws. - The movable intermediate beam is according to the invention divided into a first
intermediate beam 43 and a second intermediate beam 44, a panel ofpleated material 45 being fitted betweenbeams -
Movable beams 43 and 44 are guided with respect to fixedbeams 41 and 42 via acord guidance system cords Cords - According to a characteristic of the invention, the two
beams 43 and 44 can be coupled together, for example by means ofmagnetic fastener 51, so that in that condition the entire window opening is covered by the twopleated panels 45. By detaching the beams from each other, the upper and lower portions of the opening can each be wholly or partially covered. - It is also possible to make
pleated panels 45 of such length that one panel covers the entire window opening, so that by slidingbeams 43 and 44 up or down the window opening is covered by a panel of a single pattern or colour. This is particularly of interest ifpanels 45 differ from each other in pattern or colour, it being also possible to use a day blind and a night blind. - The embodiment of figure 9 is distinguished from that of figure 1 in that in addition to the normal
guidance cord system extra cord system Cords beam 43 at A and beams 44 at B, and are so routed via fixedbeams 41 and 42 that on raising beam 44,beam 43 is automatically moved downwards. Obviously ifbeams 43 is manipulated in an upward or downward direction, beam 44 will move downwards or upwards respectively. - In the above description it is taken that the blind is applied to a vertically disposed window opening. It is clear that the blind can also be used for a sloping or horizontally inclined window opening to obtain the same effect.
