Abstract
A shade comprising a fabric having divider strips dividing the fabric into panels of predetermined outline, each strip being sewn or otherwise secured directly to the fabric in fixed relation thereto and draw cords extending in operative relation to the divider strip so that the divider strips form focal lines for folding of the sheet of fabric as the cords are drawn.
Description




FIELD OF THE INVENTION




THIS INVENTION relates to improvements in or in relation to blinds particularly to those known as “roman shades” and more particularly but not limited thereto to, baton, cascade roman, oriental, panel, brick, diamond and other patterned roman shades. The present invention has particular application to the above named forms of roman shades but has general application to any type of shade where the present invention can be employed.




BACKGROUND ART




Roman shades are normally used as window furnishings, room dividers, privacy screens, awnings, wardrobe screens and the like applications. They can by made from natural or synthetic fabric materials. Examples of the materials include bonded fabrics, suede lined or coated fabrics, loose lined, sunscreen or sheer fabrics, canvas, plain or printed fabric.




Roman shades usually employ parallel spaced timber divider strips slidably held in pockets and operable by draw cords so that the divider strips form focal lines for folding of the shade as the cords are drawn.




Manufacture of a standard roman shade typically involves the following steps:




(i) measuring out the fabric;




(ii) hemming the fabric;




(iii) measuring the position and spacing of the lath pockets, for parallel operation of the laths;




(iv) sewing the pockets;




(v) inserting timber dowels into the pockets; and




(vi) hang the shade.




As a roman shade is a visual element any pockets that are even marginally out of parallel can create an undesirable appearance in the finished blind as the human eye is very perceptive to misalignment of this kind. Due to the construction of the roman blind, errors in measurement at step (iii) and or in sewing at step (iv) cannot be easily corrected.




One effort to simplify the process is disclosed in Australian patent application No. 74080/91 to Schon B. V. The specification discloses a retractable roman shade where shade laths are formed from an assembly comprising a strip and a fabric retainer rod insertable into the strip, the strip including a channel, the channel having a resilient clip entry receiving the retainer rod used to push fabric into and retain the fabric in the channel. This in effect displaces the fabric along the line of the strip and by using a number of these the usual focal lines for operation of the roman shade are formed. The main problem with this arrangement is that particularly for thin fabrics the strips tend to move relative to the fabric.




As a consequence of these inherent requirements for accuracy the construction of roman shades is a time consuming labour intensive process. The process also are requires a high level of machinist skill. Some of the more complex shapes such as cascade roman and baton roman are even more difficult and time consuming to make than the simpler forms.




Although variations on roman blinds have been adopted by various manufacturers in an effort to reduce labour and time none have found a simple solution.




For example, the use of an interference fit between the fabric pinched between the rod and the channel as shown in the Australian Patent application No. 740870/91 is unsuitable for thicker fabrics which simply do not fit. In addition a problem also common to other roman blinds is that the fabric gathered at the lath is effectively wasted fabric. Furthermore where a patterned or printed fabric is used the gathered fabric at the lath breaks the continuity of the pattern, again with undesirable visual effect. Simply put all the prior art lath arrangements even having regard to the time and labour factors are really only suitable for plain fabric due to this disruption of the pattern arising from gathering of the fabric at the lath.




Nevertheless it is undesirable in a Roman shade to completely eliminate pleats as the pleats give the roman shade its traditional identity but it would be desirably to retain the roman shade style but alleviate the problems of the prior art.




It is an object of the present invention to provide a method of constructing roman type blinds whereby a quick accurate result can be obtained with less time than using the prior art methods.




OUTLINE OF THE INVENTION




In one aspect, therefore, the present invention resides in a shade comprising a fabric having a plurality of horizontal divider strips adhered directly to the fabric in fixed relation thereto by sewing or equivalent technique, a plurality of draw cords extending through one or more of the divider strips so that the divider strips form focal lines for folding of the shade as the cords are drawn. The invention embraces all known means of securing a divider strip directly to the fabric in fixed relation thereto. Examples of the securing means include stapling, adhesive, fusion, welding, clamping etc.




In the traditional roman shade stitching is generally disguised by the shape and position of the pockets or the fabric colour, but generally visible stitching is considered undesirable, particularly where light can pass through stitch holes. In another preferred aspect therefore, the present invention resides in a lath assembly comprising a divider strip suitable for being adhered to a fabric in fixed relation thereto by sewing or equivalent technique and a cover member coupled to the strip. Preferably the divider strip is made from a base strip having a longitudinal fold line and the strip is formed when the base strip is folded about the fold line, the cover member being adapted to maintain the strip in the folded form. Where the strip is sewn to a fabric the cover member is automatically positioned when connected in order to prevent light being transmitted through the stitch holes.




The divider strips can comprise any stiffened material that can be adhered to the fabric. The divider strip can be made up of discrete strip elements adhered to the fabric to form an effective strip extending across the fabric. Each strip can be adhered directly to the fabric by sewing or equivalent technique or can be employed to deform the fabric to give a predetermined special effect.




In one example, the strips are formed as laminated fabric or a flexible cord. The laminated fabric is typically formed from fabric layers glued or otherwise secured together. The cord is typically a multi fibre cord having a braided outerwall enabling the cord to flex and move in response to shade fabric movement. Strip thicknesses up to 5 mm thick can be used but 3 mm is typical. Clearly this aspect allows the lath assembly to flex to some degree in response to shrinkage of the shade fabric. A similar embodiment employs a flexible cord or other flexible filamentary material where the lath assembly allows lateral and particularly longitudinal adjustment of the lath assembly in response to shade fabric compression arising through shrinkage.




For high shrinkage rates in one form the lath assembly is formed from a notched or a serpentine shaped strip, the strip typically being made from a preformed plastics or woven onto the shade fabric from a cord wound in a serpentine form. In another form the lath assembly is made from discrete elements woven or otherwise secured at spaced intervals to the shade fabric so that the elements together form an effective strip that can move in response to shrinkage of the shade fabric.




In another aspect the strips are formed as a plastics strip 1 mm to 5 mm thick and 3 mm to 30 mm wide. Where plastics are employed the strips can include ring attachment means for securing a cord guide ring or the like. Strips made of aluminium can be as thin as 0.2 mm so that it can be sewn to the fabric. In another embodiment the strips include foldable portions and possibly also clip means for securing the fordable portions together so that the strips can be pressed into the fabric and as the strips are folded and clipped together the fabric follows a predetermined deformation in order to provide a predetermined effect on the opposite side of the fabric.




Where the lath assembly comprising one or more flexible cords adhered to the fabric, the cords can be used to retain a cover member clipped to the cord to add substance to the lath assembly, with the cover member gathering shade fabric to automatically provide a particular desired shade type.




In another further aspect there is provided a lath assembly having a strip which is channel shaped and adhered directly to fabric, and a cover member having a recess in which the strip is fitted. The strip has a web portion and a side wall portion extending from each end of the web portion. The shade fabric is sewn on the exterior of the web portion. Preferably the side wall portions have flanges extending outwardly therefrom. Advantageously the recess has a shape complementary to the channel shaped strip so that the strip can be slid into the recess and be retained therein. The cover member has a ring or clip attachment means for a ring or clip to be attached thereto. The attachment means can be in the form of a restricted opening for the ring or clip to be slid in position. Preferably a plurality of rings or clips are provided spacedly along the assembly. In this invention the stitch holes on the strip are covered by the cover member to prevent ingress of light through the stitch holes.




In yet another further aspect of the present invention a lath assembly is provided and the assembly has a strip arranged within a recess of a cover member and at least one ring attachment member is secured to the cover member. The shade fabric is sewn on one side of the strip. The cover member has a restricted opening at the entrance of the recess for retaining the strip. Preferably the cover member is substantially C-shaped and includes a web portion, a side portion extending from each end of the web portion and a flange portion extending inwardly from the free end of each of the side portions. The web portion of the cover member may be provided with a groove for accommodating the stitching on the strip. The groove may be formed by a bent part on the web portion. Each ring attachment member is preferably channel shaped, and has a web portion and a side portion extending from each end of the web portion. A groove is provided in the attachment member for receiving a ring. The attachment member is provided with securing means for securing the attachment member to the cover member. Preferably a plurality of ring attachment members are spacedly arranged on the cover member. In this invention the stitch holes on the strip are also covered by the cover member and the attachment member to prevent ingress of light through the stitch holes.




In an alternative aspect of the present invention, a shade is provided, the shade comprising a fabric having a plurality of clip members secured to the fabric at predetermined positions for forming a particular pattern.




Preferably the pattern includes a brick configuration or a diamond configuration. More preferably the brick configuration represents stacking bricks. The diamond configuration includes an array of diamonds arranged in rows.




In one form the fabric has a plurality of divider strips adhered to the fabric, and the or selected clip members are connected to at least one of the divider strips.




Advantageously the clip members include a ring attachment means for accommodating a ring for a draw cord.




In another alternate aspect of the present invention, a clip member for a shade is provide. The clip member has a pair of jaws between which a part or a folded part of the shade fabric is secured. Any known means for securing the fabric to the jaws may be employed. The securing means can include sewing, stapling, gluing or clamping such as by a tube rivet.




The clip member may be formed in two compatible parts. Desirably each part includes one of the jaws and the two parts can be snap fitted together.




The clip member is conveniently configured to accommodate a cover member of the above described lath assembly. Alternatively it can be configured to accommodate the above mentioned lath assembly.

METHOD OF PERFORMANCE




Referring to the drawings and initially to

FIGS. 1



a


to


3


there is illustrated a roman blind


10


including a fabric


11


and a plurality of divider strips


12


. Selected strips


12


have guide rings


14


. A lower one of the divider strips


13


has three spaced guide rings


14


to which draw or pull cords


15


are attached so that when the end of the draw/pull cords tied together at


16


as an acorn are pulled the roman blind begins to fold as illustrated in process in FIG.


3


. Cord runners


17


are spacedly located adjacent to the top of the blind


10


. The dividers


12


having the guide rings


14


form lift lines and the other dividers


12


form breaker lines. A head board or track


18


is positioned on top of the blind


10


and a bottom lath


19


at the bottom.




There are five most common forms of roman blinds and these are illustrated in

FIGS. 4

to


8


,

FIG. 4

c.



FIG. 6

an oriental roman


10




d


and

FIG. 8

a panel roman


10




e.


The divider strips used in each case typically varies and these variations are illustrated in

FIGS. 9

to


14


.





FIG. 9

illustrates a lightweight sew on strip functioning as a lath with variations illustrated at


20


and


21


where the lath includes a strengthening projection


22


and


23


an alternative form of strengthening projection


24


.





FIG. 10

illustrates two variations of a sew on lath where the strip has a longitudinally extending projection which in section has a mushroom shape as illustrated in

FIG. 10

at


25


and


26


. This projection is used to clip a clip section


27


of a guide ring carrier


28


so that the guide ring


14


illustrated in

FIG. 15

can be secured in position at any point along the strip. Similar projections are illustrated with prime numerals to indicate compatibility with the clip of FIG.


15


. Prime numerals have been used where like features are present in different embodiments.




Where a heavier effect is required a heavy duty sew on lath is provided and examples are shown with the two examples illustrated in FIG.


11


. In order to form a panel roman as illustrated in

FIG. 8

a sew on divider strip


29


is illustrated in FIG.


12


and initially this strip is sewn to the fabric


11


to the position as illustrated at


30


and then the legs


31


and


32


are brought together to the position illustrated at


33


and then sewn again through both legs


31


and


32


. The legs are sewn closed and thereby this automatically draws in a predetermined section of the fabric. This is a simple accurate method of gathering the fabric.




It will be appreciated that the amount of fabric drawn in depends on the dimensions of the divider strip and therefore as long as the divider is placed correctly in its horizontal position and sewn to the fabric


11


along defined sewing lines the divider strip will always automatically draw in the correct amount of fabric along the full length of the strip.




A similar arrangement is illustrated in

FIG. 13

for the creation of an oriental roman. In this case a strip


34


is employed the strip


34


including two projecting leg sections at


35


and


36


and a web section


37


so that when the sections


35


and


36


are drawn together to the position illustrated at


38


the respective ends are clipped together and again the fabric will be deformed according to a predetermined geometry determined by the shape and configuration of the divider strip.




As can be seen in

FIG. 14

the baton roman can be made up using a plurality of strips


39


of the type illustrated in FIG.


14


. Usually by folding the end of the strip


39


to the position illustrated at


40


again the exact amount of fabric


11


is automatically gathered as illustrated to form in external view the baton type roman blind as illustrated in FIG.


5


.




Shown in

FIG. 16

is a lath assembly


41


. The assembly


41


has a channel shaped strip


42


and a cover member


43


having a restricted recess


44


in which the strip


42


is arranged. The strip


42


has a web portion


45


, side wall portions


46


extending from respective ends of the web portion


45


and a flange portion


47


extending outwardly from each end of the side wall portions


46


. The recess


44


in the cover member


43


is of a shape substantially complimentary to the shape of the strip


42


so that the strip


42


can be slid into the recess


44


and will remain therein during operation of a shade employing the assembly


41


. The cover member


43


has a web portion


48


, a side wall portion


49


extending from each end of the web portion


48


and a flange portion


50


extending inwardly from each free end of the side wall portion


49


. A ring attachment means


51


is arranged in the web portion


48


for receiving a cord guide ring


52


. The ring attachment means


51


as shown in

FIG. 16

has an opening


52


into which the ring


52


can be slightingly fitted.

FIG. 17

illustrates an example of the cord guide ring


52


suitable for the assembly


41


. In use the shade fabric


11


is sewn to the strip


42


along the part of the strip shown in dotted lines and the ring attachment means


51


side of the assembly


41


is normally arranged adjacent to a window. Light through the window will be blocked by the cover member


43


and therefore a person standing in front of the shade will not see any light through stitch holes in the strip


42


. The lath assembly


41


can be dimensioned to suit shades of different sizes. In an application the assembly


41


has a width of about 17.5 mm and a thickness of about 10.5 mm. The strip


42


may have a thickness of about 1.5 mm and can be made of any material with suitable stiffness and typical materials include plastic and aluminium.





FIG. 18

shows a lath assembly


60


having a strip


61


arranged within a recess


63


of a cover member


62


and a ring attachment means


67


secured to the cover member


62


. The cover member


62


is substantially C-shaped and has a web portion


64


, a side wall portion


65


extending from each end of the web portion


64


and flange portions


66


extending inwardly from respective free ends of the side walls


65


. The recess


63


has a restricted opening into which the strip


61


is arranged. The web portion


64


has a groove

19


. In the assembly of

FIG. 18

the attachment means


67


and the cover member


62


have respective complementary projecting parts


71


and notch parts


72


so that the attachment means


67


can be snap fitted onto the cover member


62


. In use the shade fabric


11


is sewn to the strip


61


at a position as shown in dotted lines in FIG.


18


and the ring attachment means


67


side of the assembly


60


is normally arranged adjacent to a window. Light through the window will be blocked by the cover member


62


and therefore a person standing in front of the shade will not see any light through stitch holes in the strip


61


. As for the assembly


41


of

FIG. 16

, the assembly


60


can be dimensioned to suit shades of different sizes. In an application the assembly


60


has a width of about 8 mm and a thickness of 10 mm. The strip


61


is about 8.5 mm wide and 1.5 mm thick. The strip


61


and the cover member can be made of any material with suitable stiffness and typical materials are plastic and aluminium.




As shown in

FIGS. 20 and 21

the lath assembly


80


for a Baton Roman blind has a fordable profiled strip


81


and a cover member


62


. The cover member


62


in this embodiment is substantially the same as the cover member


62


shown in FIG.


18


. Conveniently relevant parts of the description with reference to

FIG. 18

are incorporated herein and the same reference numbers for the member


62


in

FIG. 18

are used for the cover member in this embodiment. The strip


81


has a web portion


82


, a first side portion


83


and a second side portion


84


. The first side portion


83


extends perpendicularly from one edge of the web portion


82


and is substantially C-shaped. The second side portion


84


extends side ways from the opposite edge of the web portion


82


and is also substantially C-shaped. The first side portion


83


and the second side portion


84


are dimensioned and orientated so that when the strip


81


is folded as shown in

FIG. 21

the two side portions


83


,


84


form a substantially T-shaped configuration which can be slid into and maintained within the recess


63


of the cover member


62


. The strip


81


is thereby maintained in the folded position. In use the blind fabric


11


is sewn to the unfolded strip


81


at the positions shown in dotted line and then the strip


81


together with the sewn on fabric


11


are folded and inserted into the recess


63


. As the strip


81


has a relatively thinner section


85


in the web portion


82


the pocket formed is flat with a rounded base and this gives a perfect Baton effect. Typically the pocket formed is between 30 to 50 mm wide and the total width of the profiled strip would be between 80 to 120 mm. The assembly


80


also prevents light ingression through the stitch holes. The ring attachment means


67


shown in

FIG. 18

may be used on the assembly


80


for attaching rings or ring clips as described previously.




The lath assembly


90


shown in FIG.


23


and the profiled strip


91


shown in

FIG. 22

are for an Oriental Roman blind and function similarly to the assembly


80


and the strip


81


in

FIGS. 21 and 20

respectively. The width of the web portion


92


and the configuration of the side portions


93


and


94


of the strip


91


however are arranged to effect a rounded shape on the face of the blind. As shown the side portions


93


and


94


are substantially J-shaped and has a shoulder


95


just outside the position where the strip


91


is to be sewn to the fabric


11


of the blind. The shoulders


95


are to aid in the prevention of light ingress when the strip


91


is folded as shown in FIG.


23


. Typically the strip


91


is between 15 to 30 mm across the base depending on the size of the ridge required.




In

FIG. 24

there are shown a plan view and a side view of a clip arrangement


100


for a cascade Roman blind. The lath assembly is substantially the same as that described with reference to FIG.


18


and the description with reference to

FIG. 18

which are relevant to this embodiment are incorporated herein. The clip arrangement


100


has at least one chain which includes a cord


102


, typically 2 mm diameter, beads


104


arranged spacedly on the cord, typically at 8 mm intervals, and a clip means


67


arranged on selected beads. Preferably the arrangement


100


has between 3 and 8 chains per blind, depending on the width and the weight of the shade. The cords


102


and the beads


104


could be made of any suitable material. One such suitable material is plastic and in which the beads


104


can be moulded on the cords


102


. In use a loop (not shown) is formed at an end of each chain. Each loop is secured to a predetermined position on the headboard of the blind. Starting from the top and across the blind a cascade clip


67


is supported on a selected bead


104


of a chain, with the cord in between the two side portions of the clip


67


. The lath cover


62


for the top strip


61


of the blind is then clipped into the cascade clips


67


on the top row. The process is repeated for the beads on the next row down. The clip arrangement


100


allows each panel of the blind to be spaced higher than it would normally lie if the blind was flat, and to allow extra fullness in each panel so it loops down to give the cascade Roman look.




Referring to

FIG. 25

there is illustrated a lath


110


formed as a serpentine shaped thin plastics strip adapted to flex in response to shade fabric shrinkage particularly in the region of the narrow parts of notch parts


111


. As the shrinkage rates of some fabrics can be as high as 4% to 5% the more pairs of notches the larger the shrink rate that can be tolerated. Each notch is typically 3 mm wide×5 mm deep with 2 mm between each notch in the pair


111


. Tests have shown that each pair of notches


111


allows approximately 0.5 mm shrinkage and this can be applied for example in the case of one pair of notches per 10 mm over a metre of lath gives for 100 pair of notches providing for 50 mm or 5% shrink that can be accommodated when this sew on lath is sewn onto the shade fabric in the normal manner.




In

FIG. 26

spaced ribs


112


allow for shrinkage would be woven wide, width typically 1.2 m to 2 m wide and then cut to the required lath width and then sewn on to the fabric.




In

FIG. 27

the lath is woven from either plastic filament


113


or plastic coated fibreglass thread


114


. It is woven to the width required with fibre thread


115


. The gaps between the main filament


113


,


114


allow for compression.





FIGS. 28 and 29

illustrate use of a 4 mm cord


116


sewn directly to the shade fabric through the centre of the cord. The fabric is folded on the stitch line, thereby concealing or disguising it by reason of a cover strip


117


,


118


slid over or otherwise coupled to the cord


116


. Rings and clips as previously described can be attached to the cover strips


117


,


118


,




In

FIG. 29

there is illustrated application to an “oriental Roman” blind where two cords are sewn simultaneously to the skin of the blind at a distance apart determined by the foot of a twin needle sewing machine. Then the two cords are inserted into the cover strip


118


effectively gathering the fabric to give an oriental deformation in the front of the blind.




Other configurations as previously described can be made using this particular method simply by employing variations on the cord position and configuration of the cover strip.




In

FIG. 30

there is shown a clip member


120


for securing a folded portion


11




a


of the fabric


11


. The clip member


120


in this case incorporates the divider strip


61


and the cover member


62


described earlier with references to

FIGS. 18 and 24

.




The clip member has a first part


122


and second part


124


. Compatible portions


126


,


128


of the respectively first and second parts


122


,


124


are adapted to be snap fitted together as shown. The D-ring


70


described earlier is accommodated in the space between the parts


122


,


124


.




As shown a jaw portion


132


of the first part


122


and a jaw portion


134


of the second part


124


are arranged for receiving the folded portion


11




a


of the fabric


11


. The jaws


132


,


134


and the folded portion


11




a


are secured together by a tube rivet


136


.





FIG. 31

is a brick patterned roman shade


10


. The brick pattern is formed by deformations or open pockets between adjacent clip members


120


along the divider strip


12


. In the example shown the clip members


120
