An inhibitor system is incorporated into the covering, and the blades are allowed to open automatically when the support structure, the blades and the operation elements 466 reach an extended position.

Description

  The present invention generally relates to a panel used for a cover for a building opening and a building opening using such a panel. The panel includes a support structure, the support structure having a plurality of horizontally extending and vertically spaced strips of material on its surface, the top of the strip being The edge is fixed to the support structure at a predetermined location along the height of the support structure, and the bottom edge of the strip is slidably associated with the support structure. Pulling the bottom edge selectively upwards toward the fixed top edge creates a gap between the strips of material through which the field of view and light pass.

  This application claims priority to US application Ser. No. 11 / 348,939, filed on Feb. 7, 2006, which is filed on Apr. 8, 2005, US application Ser. No. 11/102. , 500, which is a continuation-in-part of US patent application Ser. No. 11 / 077,953, filed on Mar. 11, 2005, which was filed on Aug. 20, 2004. This is a continuation-in-part of US Patent Application No. PCT / US2004 / 027197, which is a US patent application No. 60 / 497,020 filed Aug. 20, 2003. Claims priority for the “stretchable shade provided”, all of which are incorporated herein by reference.

  The panel is used as a cover for a building opening, and a roller is provided on the top of the cover, so that the panel can be wound around the roller when the panel is retracted from an extended position across the building opening. It can be done. The cover further includes an open position in which the lower edge of each material strip is positioned adjacent to the upper edge, and a closed position in which the upper and lower edges of each material strip are maximally separated. You can move between.

  Covers for building openings such as windows, doors, archways, etc. have taken myriad forms over the years. The initial form of such a cover mainly consists of a fabric hung across an architectural opening, and in many instances the fabric is between an extended position and a retracted position relative to the opening. It was not movable.

  Retractable covers for building openings have evolved into a number of different forms, in which a piece of flexible material extends the building opening from a state wound on a roller to an extended position. A roller shade is included that is stretched across and operated in reverse.

  Another popular form of retractable cover for building openings is the Venetian blind, in which a plurality of horizontally arranged platelets are suspended by string ladders. Rotate around the horizontal longitudinal axis between the open position and the closed position, or pull up the bottom small plate and stack the small plates arranged one above the other. The entire blind can be retracted by pulling up until the stack is placed adjacent to the top of the building opening.

  Vertical blinds have also been developed so that the platelets or slats are positioned vertically and the cover can be rotated about the longitudinal vertical axis to move between the open and closed positions. It is the same as the Venetian blind except that. Further, the platelets or vanes can be moved horizontally and stacked adjacent to one or both edges of the building opening when the cover is retracted, or the platelets or vanes cross the opening. It can also be arranged to be evenly spaced.

  In recent years, cell-type shades have gained popularity and many different variations have been made. In one popular cellular shade, horizontally disposed foldable material tubes are connected and stacked vertically to form a panel of such tubes. When the panel is fully extended, it covers the building opening, but the panel lifts the bottom cell, folds each cell over it, and stacks relatively thin cells on top of the opening. It can be retracted by pulling it up until it is stacked adjacent to it.

  Another popular cellular product is a sheet of translucent material, such as a thin fabric, that stretches vertically in a pair of spaced apart, with a plurality of horizontally disposed vanes extending between them. A pair of sheets is used. The vanes may be rigid or flexible and rotate about the longitudinal axis when the vertical sheets of material are moved in opposite vertical directions. The entire sheet and vane panel can be easily wrapped around a roller to retract the cover.

  A modified version of the vertical blind has also recently been developed, where a plurality of vertically extending vanes are interconnected with a sheet of fabric, eg a thin cloth, along one vertical edge. The cover is similar to a draped product, but the slats placed behind the thin fabric can be rotated around the longitudinal vertical axis, allowing the field of view and light to pass through the thin fabric Can be selectively blocked. Of course, the slats and attached fabric can also be stacked on one or both sides of the building opening when the cover is retracted from its extended position across the building opening.

  The design of a cover for a building opening is believed to encompass a myriad of different forms, which are driven by both utility and aesthetic factors. Over time, one of these factors will give instructions to the other, but various combinations of components within a consumer's residential or commercial space where both the utility and aesthetic requirements are met. It has always been developed to satisfy their insatiable dryness on the covers for modern building openings.

The purpose of developing the present invention is to satisfy such a desire.
US patent application Ser. No. 11 / 348,939 US patent application Ser. No. 11 / 102,500 US patent application Ser. No. 11 / 077,953 PCT patent application PCT / US2004 / 027197 US Provisional Patent Application No. 60 / 497,020 US Pat. No. 6,289,964

  The present invention relates to a cover for a building opening and a panel used therefor, the panel including a support structure on which a plurality of adjacent horizontal stretches are vertically spaced. A vane plate or a strip of material, which is arranged at a distance, is attached. The spaced slats are in a flat and closed position, and a retracted open position where the slats protrude from the support structure and form a space between the slats and the field of view and light. And move between.

  The support structure can take a number of forms, including a sheet of flexible material, such as a thin fabric. It may be a plurality of vertically extending flexible elements arranged in a spaced parallel relationship and in a common plane. In the preferred form of the invention, the slats are arranged horizontally, but those skilled in the art will also be able to utilize the teachings of the invention in covers where the slats extend vertically. .

  The slats can take many different forms and can be made of various materials such as woven or non-woven fabrics, vinyl materials. The slat may be a flexible, semi-rigid or rigid material with a fold line that can move the slat between an open position and a closed position, if desired. A vane is typically a strip of material having upper and lower edges that extend horizontally across a vertical support structure. The upper edge of each strip is secured to the support structure at a location spaced perpendicular to the next adjacent vane so that the remaining portion of the strip is the upper edge As a whole, a panel of material is formed comprising a plurality of strips of material supported by the support structure. Since the lower edge of each strip is slidably connected to the support structure, it can be moved vertically towards the upper edge of the strip and away from the upper edge. Moving the lower edge toward the upper edge causes the strip to expand or bulge out of the support structure, leaving the panel or cover open so that the field of view and light can pass between the strip or vane of material. become. When the lower edge of the strip of material or vane is lowered, for example by gravity, to a position that is farthest from its upper edge, the strip of material becomes substantially common with the support structure. It is flat on the surface, preferably with a slight overlap of material strips, blocking the view and light passing through the panel or cover. In this closed position, the panel or cover is wrapped around a roller in the head rail of the cover so that the cover can be easily moved between the extended position and the retracted position.

  As previously mentioned, the strip of material can take many forms, and a closed cell may be formed therebetween as a double layer of strip of material. A separate strip of material may be placed on one or both sides of the support structure so that the support structure extends along one side edge of the cell or through the center of the cell. .

  As mentioned above, the support structure is in the form of one or more sheet materials that support the upper edge of each vane at a predetermined location along the height of the sheet material or sheets. Also good. Alternatively, a plurality of flexible, vertically extending elongated lift elements may be replaced with one or more sheet materials, in which case the upper edge of each vane is replaced with a flexible lift element. , Will be fixed at corresponding positions along its length. In any case, in addition to the sheet material or lift elements, a plurality of flexible operating elements are also used, which are fixedly connected to the lower edge of each vane, As it slides relative to the upper edge, the lower edge of the vane can be raised or lowered to move the attached vane and panel between the open and closed positions.

  Other aspects, features and details of the invention will be more fully understood when the following detailed description of the preferred embodiment is read in conjunction with the drawings and read the claims.

  A first embodiment 100 of a panel and cover for a building opening according to the present invention is shown in FIGS. 1-16. It can be seen that the cover panel 102 includes a support structure 104, a plurality of vanes 106 connected to the support structure, and an operating element 108 for moving the vanes between an open position and a closed position. . The support structure of the first disclosed embodiment is in the form of a thin cloth flexible sheet, but uses one or more flexible sheets of different materials of different structure and transparency. May be. The seat is rectangular with an upper edge 110 and a bottom edge 112, a left edge 114 and a right edge 116, and a weighted bottom rail 117 is secured to the bottom edge 112. Perhaps best seen in FIGS. 5-8, the support sheet 104 is suspended along its upper edge 110 from a generally cylindrical roller 118 disposed within the head rail 120 for the cover. Cage (FIGS. 4-6), the rollers are mounted in a conventional manner so that they can be selectively rotated about the horizontal central axis in the opposite direction. The roller 118, the head rail 120, and the panel 102 include the cover 122 of the present invention.

  The roller 118 is provided with the same first groove 124 and second groove 126 that are spaced apart in the circumferential direction, and this groove opens through the outer periphery of the roller. One groove supports the upper edge portion 110 of the support sheet 104. The upper edge of the support sheet is folded so that it can be inserted longitudinally into the groove through the rod through the fold, where the groove opens through the outer circumference of the roller It is hold | maintained by a pair of lip | rip currently formed in this. Since the lips are spaced apart by a distance smaller than the diameter of the rod, the folded upper edge 110 of the rod and the support sheet is confined in the groove 124.

  A plurality of elongated blades or sheet members 106 are suspended from the front surface of the support sheet 104 in the horizontal direction at positions spaced apart in the vertical direction. Each vane is rectangular and is made of a semi-rigid material having a fold line 128 along a substantially longitudinal centerline of the vane material. Each vane has an upper edge portion 130 and a bottom edge portion 132 that are parallel to the broken line, and the upper edge portion is formed along the upper edge portion that is fixed to the support sheet in the manner described below. It has a rectangular tab 134 that is folded inward and downward. The bottom edge 132 of each vane has a rectangular tab 136 folded back inwardly and is slidably associated with the support sheet, as will be further elucidated below. The exposed or front surface of each vane between tabs 134 and 136 is on the vane below which each vane is adjacent when the cover is in the closed position of FIGS. 1, 5, 6 and 9-13. It has a width that overlaps. In the closed position, each vane appears to be substantially flat and parallel to the support sheet 104.

  The panel 102 and the cover 122 further include a plurality of flexible, vertically extending operating elements 108 spaced horizontally across the width of the panel, the upper end of the operating elements. The part is fixed in the second groove 126 of the roller 118. This attachment is performed by tying the upper end of each flexible operating element to a rod inserted in the second groove. Desirably, the operating elements are centered along the length of the roller 118 and are evenly distributed along the length of the roller. When the operating element is a cord, it is desirable to use, for example, a 1-10 cord, particularly a 2-4 cord every 3 inches of roller length. However, more cords per inch are desirable when using thin or weak cords, and fewer cords per inch may be used when using thick or strong cords.

  Each flexible operating element is suspended vertically across the entire height of the panel and is secured to the bottom edge 132 of each vane at spaced locations along its length, When the operating element is lifted, the lower edge of each vane is simultaneously raised towards the upper or upper edge 130 to form a gap or open space 138 (FIG. 3) between the vanes, which is used as a field of view. Light can pass through. As can be seen, each vane is made of a semi-rigid material and has a fold or crease along the longitudinal center so that when the bottom edge 132 is moved toward the top edge 130, the vane The plate is folded or expanded forward as shown, for example, in FIGS. 2 and 3 to form a rectangular plate pivotally connected vane plate on the upper side 140 and the lower side 142. The blades have a cross-section that changes from a flat state at the closed position in FIG. 1 to a triangle at the open position in FIGS. 2 and 3. The flexible manipulation element 108 is shown as a single fiber, but can take a variety of other forms. Examples of other forms include, but are not limited to, fabric or other material strips, synthetic or natural yarn cords, specifically polyester yarns, polyethylene yarns such as DSM Dyneema RTM yarns, Dupont The company's Kepler RTM, Nomex RTM, and Teijin Twaron RTM yarns such as aramid yarns, Honeywell Performance Fiber's Spectra. The operating element is preferably transparent and high-strength and non-stretchable even at high temperatures such as those produced by windows exposed to direct sunlight. Further, the cord may be not only a single fiber but also a multifilament yarn, but a monofilament yarn is particularly desirable. Further, the cord preferably has a diameter of 0.01 to 0.02 inches, and particularly preferably has a diameter of 0.30 to 0.12 inches. The vane 106 itself may also be made of any suitable material including, but not limited to, woven or non-woven fabric, vinyl, or other such materials.

  The upper edge 130 of each vane is connected to the support sheet 104 in the manner best seen in FIGS. 14-16. A mounting strip 144 is used to connect the tab 134 to the support sheet along the upper edge of each vane, and the mounting strip extends the full width of the panel 102 or cover 122. Has a height substantially equal to the height of The mounting strip has a core or substrate 146 that spans the entire dimensions of the mounting strip 144 and has strips of double-sided adhesive on the front and rear surfaces. On the front side of the substrate 146 is a continuous strip 148 of double-sided adhesive, which is the back side of the tab 134 along its length and on top of the associated slats. Is bonded along its entire length. However, on the rear surface of the substrate 146 is a plurality of longitudinally aligned double-sided adhesive strips 150 that are secured to the rear surface of the substrate at a distance between which the adhesive A gap or space 152 extending in the vertical direction without any gap is formed. The adhesive strip on the rear surface of the substrate is such that the operating element 108 extends the interrupted connection line between the upper edge of the vane and the support sheet through the gap or space 152 made therein. It is fixed to the front surface of the support sheet 104 so that it can slide smoothly.

  On the rear surface of the substrate 146, there is an option of using a plurality of double-sided adhesive strips 150. One example is that a gap extending in the vertical direction or a gap 152 forming a space 152 is formed on one surface. Is to use a continuous double-sided adhesive strip. Further, an adhesive line is used instead of an adhesive tape, and the adhesive line is intermittently applied so that a vertically extending gap or space 152 is formed between the adhesive lines. Good. As yet another alternative to interconnect the rear surface of the substrate 146 to the support sheet 104, intermittent ultrasonic welding may be used instead of multiple strips of double-sided adhesive or other alternatives described above. It may be used. When using ultrasonic welding, it is important that the welding does not adversely affect the material to the point that it does not operate repeatedly over a long period of time in the manner described below. The lower edge 132 of each vane has a core or substrate 156 that extends across the entire width of the panel 102 and a height slightly lower than the height of the target tab 136 on the lower edge of the vane. The operating strips 154 are connected to the respective operation elements 108. The substrate 156 has a continuous strip 158 of double-sided adhesive on the front surface thereof, and is fixed to a tab 136 at the bottom edge of the slat, and the operation element 108 is adhered and captured between the two. . In this way, as can be seen, the operating elements are secured to the tab 136 along the lower edge of each vane in spaced positions, but the upper edge 130 of each vane Slidably passes through a break line of attachment to the support sheet 104. This system for attaching the slats to the support sheet and the operating element is probably best seen in FIGS. 12, 13, 15, and 16.

  As mentioned above, the number of operating elements is arbitrary, but when a sufficient number of operating elements are used, that is, when there are many codes per inch, every other code is It can also be attached only to the bottom of the vane and the second groove of the roller. The rest of the cord can only be attached to the top of each vane and the first groove 124 of the roller, eliminating the need for a support sheet and being an element that extends between the top of each vane and the first groove 124. It can also be replaced.

  As is probably better understood with reference to FIGS. 10 and 11, the upper tab 134 of each vane 106 has a slightly lower height than the tab 136 on the lower edge of each vane, The tab 136 at the lower edge of each vane overlaps the upper edge of the vane immediately below in the closed position of the panel. Thus, when the panel 102 is in the closed position of FIGS. 1 and 9-11, the field of view and light through the panel are completely blocked.

  The operation of panel 102 and cover 122 is probably best seen in FIGS. 4-8. In FIG. 4, the panel is fully retracted and fully wound around the roller 118, with the lower edge of the panel positioned along the back side of the roller. As the roller is turned counterclockwise, the panel, from its closed position, overlaps the next adjacent lower slat, with each slat 106 being substantially flat, as shown in FIGS. 4-8. Fall with gravity. The panel extends until it reaches a position where the cover extends almost fully in FIG. 6 and the mounting groove 124 of the support sheet 104 is on the top of the roller and the mounting groove 126 of the operating element 108 is behind the roller. Remains in this flat closed position. When the roller is further rotated counterclockwise to the position of FIG. 7, the second groove 126 to which the operating element is fixed moves forward, so that the operating element is pulled upward with respect to the support sheet as shown in the figure. And the operating element is lifted with respect to the support sheet, so that the operating element simultaneously raises the lower edge 132 of each vane so that the vane is folded or buckled outwardly and each vane The lower edge leaves the upper edge 134 of the next adjacent lower vane. When the roller continues to rotate counterclockwise to the position of FIG. 8, the limit of counterclockwise rotation, the second groove 126 comes near the front of the roller, filling the bottom edge of each vane. Since the panel is pulled up, the panel and the cover are fully opened, and the gap 138 between the blades is maximized. In the fully opened position, the blade 106 has a cross-sectional shape like an isosceles triangle.

  When the roller 118 is rotated in the reverse direction, ie, clockwise from the position of FIG. 8, the second groove 126 first moves to the position of FIG. 7, and the lower edge 132 of each vane plate is moved to the position of FIG. In this state, the blades are fully closed and become substantially flush with the support sheet 104. When continuously rotated clockwise, the panel in the closed position wraps around the roller until it reaches the retracted position of FIG. 4 again.

  As can be understood from the above description, the cover 122 can be fully retracted as shown in FIG. 4, or the panel can be moved to a desired degree as shown in FIG. It can also be lowered to a fully extended state, but with the vane plate 106 closed. When the roller 118 is further rotated, the blades themselves open, and a gap 138 is formed between the blades so that the field of view and light can pass through the panel. As can be appreciated, the slats can be opened only when the panel 102 is fully extended, and with the slats closed, the panel can be stretched across the building opening to the desired degree. it can.

  A second embodiment 160 of the present invention is shown in FIGS. 17-19, where the cover also includes a roller 118 in which the support sheet 104 and the operating element 108 are the same as in the first embodiment. Connected with. However, in this embodiment, the slats made of some semi-rigid material or strips of material 164 have no fold lines or creases, so that the slats hang down. When the blade is moved from the closed position of FIG. 17 close to the support sheet toward the open position, the vanes go through the partially open position of FIG. 18 in a substantially symmetric manner. 19 expands forward to the fully open position of FIG. It will be appreciated that due to the nature of the semi-rigid material from which the vanes are formed, the vanes protrude or extend in a substantially horizontal direction away from the support sheet.

  A third embodiment 166 of the present invention is shown in FIGS. 20-22, and as shown, the roller 118 is again provided with two mounting grooves 124 and 126, and the support sheet 104 is one side. The operating element 108 is attached to the second groove 126. The blade or material strip 168 is connected to the support sheet and the operating element in the same manner as in the first and second embodiments, but the material of the blade is not rigid. Rather, the material of the slats is somewhat flexible so that it hangs down regardless of whether the slats are opened or closed. In the closed position shown in FIG. 20, the lowest area of each vane overlaps the uppermost area of the next adjacent lower vane, but when the vane is partially opened, each vane The lower edge of the plate is somewhat raised so that a gap 138 is established between the vanes. As shown in FIG. 22, when the lower edge of each slat is pulled up fully, the gap between the slats becomes larger than the partially open position in FIG. Not as large as the first and second embodiments.

  In the fourth embodiment 170 of the cover shown in FIGS. 23-24, the roller 118 is provided with mounting grooves 124 and 126 spaced apart in the circumferential direction, and the support sheet 104 is one side. The operating element 108 is attached to the other groove 126. In this embodiment, the slat 172 is also connected to the support sheet and the operating element, as described in the previous embodiment, and the slat is made of a semi-rigid material and extends horizontally in the longitudinal direction. The fold line or crease 174 is made in the same shape as the blade of the first embodiment shown in FIG. 1-16 except that the bottom edge 178 of the blade is closer to the upper edge 176. It has been. Thus, the vane is again divided into rectangular sections of an upper portion 180 and a lower portion 182, but the upper section is slightly smaller than the lower section. When the vane is moved from the closed position of FIG. 23 to the fully opened position of FIG. 25 through the partially opened position of FIG. 24, the cross section forms an isosceles triangle in the first embodiment. In contrast, it forms a substantially right triangle.

  A fifth embodiment 184 of the cover of the present invention is shown in FIGS. 26-28. In this embodiment, the roller 118 is also provided with a first groove 124 and a second groove 126 for attaching the support sheet 104 and the operation element 108, and the blade 186 is described in the previous embodiment. As it is, it is attached to the operating element. However, in this embodiment, each vane 186 has an outer material strip 188 and an inner material strip 190, which is the fourth embodiment of FIGS. 23-25 above. The inner material strip is a flexible material as in the third embodiment of FIGS. 20-22. The inner flexible material strip 190 is secured to the outer semi-rigid material strip 188 along the top and bottom edges, and the combined strip is similar to the previously described embodiment. Again, the operating element 108 slides past the attachment line to the support sheet at the top edge of each vane but along the bottom edge of each vane. It is fixed to the operating element. Thus, when the cover is moved from the closed position of FIG. 26 where the vane is substantially coplanar with the support sheet and flat, the vane goes through the partially open position of FIG. FIG. 28 moves to the fully open position, where in the fully open position the flexible strip of material is confined within the outer semi-rigid strip of material used for the vane. A closed cell is established between the pieces. The cell, of course, is open at both ends adjacent to opposite sides 114 and 116 of the support sheet. This embodiment considers the functional characteristics and aesthetic diversity of the cover, for example, the inner flexible material strip is an opaque material and the outer semi-rigid material is translucent or transparent. In the fully open position of FIG. 28, the field of view is opened between the blades, but in the closed position of FIG. 26, it is completely blocked by the opaque inner material. Other variations are readily apparent, for example, the inner and outer layers may be different in color or transmissivity to produce different effects.

  A sixth embodiment 192 of the present invention is shown in FIGS. 29-30. As can be seen, this embodiment is very similar to the embodiment of FIGS. 26-28, where again the roller 118 is provided with a first groove 124 and a second groove 126, Both grooves are on the diametrically opposite side, and the support sheet 104 is suspended from the front of the roller, not the rear. Also in this embodiment, the support sheet is fixed in one groove 124, and the flexible operation element 108 is supported in the other groove 126. The vane 194 has a semi-rigid outer strip of material 196 and a flexible inner strip of material 198 that is connected to the support sheet and operating element as in the embodiment of FIGS. is doing. In this embodiment, the vane is moved from the closed position of FIG. 29, which is substantially flush with the support sheet, through the partially opened position of FIG. 30, to the fully opened position of FIG. Is rotated by rotating counterclockwise counterclockwise.

  A seventh embodiment 200 of the present invention is shown in FIGS. 32-34, where again a roller 118 having a pair of mounting grooves 124 and 126 removes the support sheet 104 from one groove 124 as shown. The operating element 108 is supported from the second groove 126. In this embodiment, the slats 202 and 204 are simply strips of material having tabs 206 bent inwardly downward along the upper edge, each strip being slightly inward in cross-section. It is hollow. Every other vane 202 starting at the top of the cover panel and facing downward has tabs secured to the support sheet 104 along its upper edge as in the previously described embodiment. Thus, the operating element 108 can slide through the intermittent connection line. Every other vane, starting with the second vane 204 from the top, is fixed to the operating element 108 along the upper edge, similar to the bottom edge of the vane of the previously described embodiment. The tab 206 is provided. In this way, the cover can be moved from the fully closed position of FIG. 32 where each vane overlaps the next adjacent lower vane through the partially open position of FIG. In this partially open position, every other slat is lifted upwards by the operating element starting from the second slat from the top so that the slat is the next adjacent upper slat 202. And slides into a pocket 208 formed between the support sheet 204. When the cover is fully opened as shown in FIG. 34, every other slat 204 starting with the second slat from the top slat is between the next adjacent upper slat 202 and the support sheet. , Which are substantially completely confined in the pocket 208 of the other, a gap or opening 138 is formed between the pair of vanes 202 and 204 through which light and field of view pass.

  An eighth embodiment 210 of the cover of the present invention is shown in FIGS. 35-37, where, as can be seen, the roller 118 has two mounting grooves spaced circumferentially apart. 124 and 126, one groove 124 supports the support sheet 104, and the other groove 126 supports the plurality of operation elements 108. In this embodiment, the slat 212 is similar to the slat in the embodiment shown in FIGS. 23-25, and the slat includes an upper tab 216 and a lower tab 218 connected to the support sheet and the operating element, respectively. A fold line 220 that includes a semi-rigid strip 214 having a longitudinal center slightly above it forms an upper compartment 222 and a lower compartment 224. The slats move between a closed position where the slats are substantially coplanar with the support sheet 104 and an extended position where the slats protrude forwardly from the support sheet in a substantially right triangle. be able to. In this embodiment, an arcuate rigid or semi-rigid rectangular platelet 226 is secured to the upper section 222 of the semi-rigid vane component such that its inner edge 228 is adjacent to the support sheet. Yes. The platelet 226 has a height approximately twice that of the upper section 222 of the slat, so that when the slat is in the open position of FIG. It protrudes from the support sheet for a long distance. When the blade is closed as shown in FIG. 35, the small plate overlaps the small plate adjacent immediately below. FIG. 36 shows the vane in a partially open position. As can be seen, the gap or opening 138 begins to form between adjacent vanes, and the gap or opening is maximized when the vane is fully opened, as shown in FIG. The platelet 226 is slightly inwardly or downwardly depressed in cross section, giving the cover an attractive appearance whether it is open or closed.

  A ninth embodiment 230 of the present invention is shown in FIGS. 38-40 and this embodiment is also a roller 118 having two mounting grooves 124 and 126 spaced circumferentially apart. One groove 124 supports the support sheet 104 and the other supports the flexible operation element 108. The cover vane 232 has an inner component 234 and an outer component 236, which is a flexible strip of material similar to that disclosed in the embodiment of FIGS. 20-22. It is. The upper edge of the outer material strip is secured to the support sheet 104, the operating element can be slid through its connection, and the lower edge of the outer strip is the implementation of FIGS. 20-22. It is fixed to the flexible element 108 as in the form. The component 234 inside the vane is a second flexible strip that is lower in height than the first flexible strip 236, so that when the cover is in the open position of FIG. The flexible strip hangs inside the outer flexible strip, but when the cover is closed as shown in FIG. 38, the inner flexible strip 234 supports It is substantially flush with the sheet. The outer strip 236 hangs so that it looks beautiful even when the cover is closed. FIG. 39, of course, shows the cover in a partially open position, with relatively small gaps or openings 138 formed between adjacent vanes, the openings shown in FIG. It becomes maximum when it is fully open. The purpose of using the inner and outer strips of material for the slats is numerous and not limited, but they are opposite to each other of the support sheets that are open at both ends of the panel to improve barrier properties The fact that it forms a closed air pocket except along side sides 114 and 116 is mentioned. Furthermore, the inner and outer material strips may have different blends of transparency and color for variable aesthetics.

  A tenth embodiment 238 of the present invention is shown in FIGS. 41-43, in which the roller 240 is provided with a single groove 242 for attaching the upper ends of the plurality of operating elements 108. ing. The roller is rotatably mounted in a head rail 244 having an inverted L-shaped cross-sectional configuration. Thus, the head rail forms a front plate 246 and an upper plate 248, which supports a banner in the form of a vane 250, which is made of a somewhat flexible material. Preferably, the lower edge of the vane loop extends beyond the lower edge of the head rail front plate. Subsequent horizontally extending vanes 252 with the same cross-sectional configuration are supported on a support sheet 104 that is suspended vertically from the front plate of the head rail. Each blade 252 has an upper edge 254 and a bottom edge 256, but the upper edge and the bottom edge are the embodiment of FIG. 1-16, and the upper edge of each blade is a support sheet. Are simultaneously fixed to the support sheet along the horizontal line by intermittent adhesive lines 258 in the same manner as they are connected to. Each vane 252 following it is attached to the support sheet in the same manner, with the lower edge of each vane loop slightly overlapping the upper edge of the next adjacent lower vane. ing. Since the operating element 104 passes through a gap or opening (not shown) in the adhesive line 258 that connects the vane to the support sheet, it can be slid through the adhesive line. The lower end of each operating element 108 is fixed to a lift bar 260, which may be any rigid or semi-rigid bar such as polyethylene plastic. When the roller 240 is rotated counterclockwise with the cover fully extended as shown in FIG. 41, the operating element is wound around the roller and the lift bar is pulled up, as shown in FIG. Engage with the bottom adhesive line. As the roller continues to rotate counterclockwise, the lift bar accumulates the blades with the adhesive lines adjacent to the head rail, as shown in FIG. Overlaid.

  FIG. 44 shows another embodiment 262 of the inventive cover that is very similar to the embodiment of FIGS. 1-16. In this embodiment, the support sheet 104 drawn as a thin cloth sheet is connected to a roller (not shown) along one groove on the outer periphery of the roller. A plurality of semi-rigid vanes 264 having folded tabs 266 along the upper and lower edges and a longitudinal fold line 268 substantially along the longitudinal center are supported on a support sheet. The slats are supported by the support sheet along the upper edge by intermittent strips of adhesive 270 so that a gap or space is formed, which is shown in the embodiment of FIGS. 1-16. Instead of the single fibers, the operating element 272, which is a ribbon or tape material in the embodiment of FIG. 44, passes. The ribbon or tape 272 has an upper end fixed in a second groove of a roller (not shown) spaced circumferentially from the first groove, so that the cover Operates in the same manner as the cover of FIGS. 1-16 except that the monofilament is replaced by a ribbon or tape 272 that is secured to the lower edge of each vane 264 and rotates the roller. As the ribbon or tape is moved upward, the lower edge of each vane is pulled up relative to the upper edge.

  FIGS. 45-52 illustrate a twelfth embodiment 274 of the inventive cover, again provided with a roller 118 having mounting grooves 124 and 126 spaced circumferentially apart. Yes. In this embodiment, the support structure, which has been shown as a sheet of thin fabric in the previously described embodiments, is a parallel, flexible lift element 278 arranged with a plurality of vertically extending spaces. Yes, in this embodiment it is monofilament, but as can be appreciated, other flexible elements such as strings, strips or ribbons of material, natural or synthetic cords, etc. may be used. The lift element is fixed at the upper end in the first groove 124 of the roller. The operating element 108 is the same as the previously described embodiment, where again a plurality of operating elements are suspended vertically in a spaced parallel relationship, the upper end of which is the second groove 126 of the roller. It is fixed inside. The vane 280 of this embodiment is composed of a front component 282 and a rear component 284, both components being made of a semi-rigid material, similar to the embodiment of FIGS. 1-16, It has a rectangular tab 286 along the upper and lower edges of the component, and a fold line 288 extending longitudinally about its longitudinal center. The vane components 282 and 284 are mounted on opposite sides of the lift element 278 and the operating element 108 in a back-to-back opposite relationship. The slat component 282 on the front side of the panel is slightly larger than the slat component 284 on the rear side, so that it will face down a slightly longer distance along the length of the lift element for the purposes described below. Stretch. The upper edges of the slat components are coincident with each other in the attachment location to the lift element.

  The upper edge of each vane component is secured to the lift element by an adhesive strip 290, between which a gap is formed through which the operating element 108 can slide. Since the vanes 280 are spaced apart by a predetermined distance, in the closed position of the cover, the lower edge of the front component 282 of each vane is completely closed as shown in FIG. On the upper edge of the front component 282 of the lower slat adjacent to.

  The lower edge of each vane component is secured to the operating element 108 at a predetermined location along the length of the operating element, so that the cover is moved to the open position by lifting the operating element relative to the lift element. In doing so, the lower edge of the slat is pulled toward the upper edge of the slat.

  During the operation of the cover, the panel of the slats 280 is suspended from the rear side of the roller 118, as shown in FIG. 46, and the groove 124 supporting the lift element 278 is located substantially at the top of the roller, A groove 126 supporting the operating element 108 is located behind the roller. Since the panels are in a fully extended position where the slats are closed, each slat is flat, substantially parallel to the lift element and the operating element, and coplanar. To retract the cover, simply rotate the roller clockwise and wrap the vane panel around the roller. Since the roller is rotated counterclockwise, in the partially opened position, as shown in FIG. 47, the groove 124 fixing the lift element is substantially behind the roller and the groove supporting the operating element. 126 is located approximately at the bottom of the roller. As can be seen, as the groove 126 is displaced from the lift element, the operating element is raised and the bottom edge of each vane is raised. When the roller is further rotated counterclockwise, the cover moves to the fully open position of FIG. 48, and a gap or space 138 through which the field of view and light pass is formed between the blades. As can be seen, in this embodiment of the invention, closed cells that are open at opposite ends of the panel are formed by vanes, which are forward and backward from the lift and operating elements. Stretching. This type of cell-type cover has practical advantages, for example, in providing barrier properties that cannot be achieved with conventional roller shades.

  A thirteenth embodiment 292 of the present invention is shown in FIGS. 53-55 and again utilizes a cylindrical roller 118 having two grooves 124 and 126 spaced circumferentially apart. One groove 124 is used to fix the upper end of the set of lift elements 278, and the other groove 126 is used to fix the upper end of the set of operating elements 108. As in the embodiment of FIGS. 45-52, each vane 294 has a front component 296 and a rear component 298, and the vane is substantially teardrop-shaped in cross section. The front vane component 296 has a tab 300 that extends inwardly downward along its lower edge, and the rear vane component 298 extends inwardly upward along its upper edge. And the slat components are substantially the same configuration, but are reversed with respect to each other. Again, the upper edge of each vane is connected to the lift element 278 by a strip of adhesive so that a space is formed between them, and the operating element 108 is slidable in that space. It can pass through and is secured to the lower edge of the vane component. This embodiment of the present invention operates in the same manner as the embodiment of FIGS. 45-52, first referring to FIG. 53, because the cover is fully extended but in the closed position, the front vanes of each vane plate. The plate component slightly overlaps the next adjacent lower vane, which forms a closed cell that is open at both ends of the panel. The lift element and the operating element extend vertically through the center of the cell formed by the vane. When the cover is moved toward the open position shown in FIG. 54, the lower edge of each cell is raised toward the upper edge, and the cell is adjacent, with the cover fully open as shown in FIG. An opening or space is formed between the cells and expands both forward and backward until the field of view and light pass through it.

  A fourteenth embodiment of a panel according to the present invention is shown in FIGS. 56a-56c. In this embodiment, a plurality of strips or vanes 304 are supported on a support structure 306, which can again be a sheet material such as a thin cloth or a plurality of flexible support elements. The strips or slats are made of a rigid or semi-rigid material and are alternately folded in opposite directions at equally spaced locations 308 to form a bend line along the line. A generally flat component portion 309 of a piece can be pivoted relative to an adjacent component. A downward flap 310 is provided along the upper edge or edge zone of each strip to allow the flexible control or operating element 312 to slidably pass through as defined in the previous embodiment. It is fixed to the support structure 306 with an adhesive in such a way that a gap can be formed. The control element is secured to the bottom edge or edge zone of each strip or vane along an upward flap 314 provided therewith. Therefore, when the operating element is moved up and down, as the operating element slides through the gap provided at the connection with the support structure of the downward flap 310 at the upper edge of the vane plate, The side edge moves up and down.

  FIG. 56a shows a fourteenth embodiment of the present invention in a fully extended and closed state, with each strip or vane 304 facing a substantially flat orientation adjacent the front surface of the support structure 306. FIG. In addition, it is fully extended and suspended. When the operating element 312 is moved upward by rotating the roll bar 316 suspending the panel counterclockwise when the cover is fully extended, the lower edge of each vane is in the support structure. Each slat is collected upwards by a crease that is lifted against and pre-formed on the slats, causing its component part 308 to pivot relative to the adjacent component part, so that the opposite ends A triangular cell 318 is formed in which is open. The formed cell is shown in FIG. 56b, and FIG. 56c shows a state in which the vane plate is in a fully retracted position and a gap 320 is formed therebetween.

  57-64 show a hardware system that can be associated with any of the panels described so far. To describe the hardware system, except that the slats 324 are made of a slightly stiffer material than in FIGS. 38-40 so that they protrude outwardly from the support structure 326 rather than depending on it. Thus, the general type of panel 322 disclosed in FIGS. 38-40 is shown.

  57, head rail 328 for supporting cover material panel 322 includes a pair of end caps 330 supporting a blindfold plate 332 extending in the longitudinal direction in the front as shown. The blindfold is supported in a conventional manner using mounting brackets 334 (shown in dotted lines) that extend partially across the top of the head rail and can be secured to a frame around the building opening. Designed to be. The head rail is typically located adjacent to the top of the building opening and includes a roller or roll bar 336, as shown in FIG. 59a, around which a panel of material 322 covers the cover. It is selectively wound at the retracted or partially retracted position. The roller is reversibly driven by an endless control cord 338 via an actuation mechanism of the type disclosed and described in US Pat. No. 6,289,964, the disclosure of which is incorporated herein by reference. As can be seen, in this actuation mechanism, the endless control cord 338 is rotated in either direction and the roll bar 336 is rotated correspondingly to move the panel of cover material between the extended and retracted positions. be able to. In the extended position, the panel extends out of the roll bar as described in connection with the panel embodiments described above, but is suspended from the roll bar and when retracted, the panel is Wound around the roll bar. Such operation will be described in detail below.

  In FIGS. 59-62, the cover panel 332 includes a bottom rail 340 previously disclosed in more general terms as element 117, as shown. Using the bottom rail adds weight along the bottom edge of the panel of material and encourages the panel to fall by gravity when allowed by operation of the roll bar supporting the panel. Hereinafter, as will be described in detail, the bottom rail is designed to cooperate with the support structure 326 and the operating element 312 and is ultimately associated with the panel so as to provide a visually appealing lower edge to the cover. This is a hinged two-compartment rail. The pivoting bottom rail is further designed to cooperate with an adjustable stop 344 provided on the head rail to limit the rotation of the roller in the retracting direction. That is, when the panel is fully retracted into the head rail, the bottom rail 340 engages the adjustable stopper 344 to prevent the roll bar from rotating further in that direction. The cooperation of the adjustable stopper with the head rail will be described in more detail hereinafter.

  Turning to FIG. 59a, as described generally above in connection with various other embodiments of the panel, the roll bar 336 is adapted to secure the support structure 326 and the upper end of the operating element 312 respectively. Grooves 346 and 348 disposed on opposite diametrical sides. 59b and 59c, the lower edge of the support structure and the lower edge of the dummy vane or strip 350 secured to the lower end of the operating element 312 are connected to the bottom rail 340. It is fixed inside. In these drawings, it can be seen that the bottom rail is comprised of a large extrusion section 352 and a small extrusion section 354, the larger section being shown below the smaller section. Both compartments are interconnected with a hinge element 356, which is an elongated strip of plastic or other rigid or semi-rigid material with beaded edges 358. The dummy strip 350 is preferably a strip of the same material used for the panel slats or strips 324. The dummy strip has an upper edge (not shown) that is secured to the lower edge of the bottom slat or strip 324 of the panel and a lower edge 362 that is secured to the bottom rail. This will be described below.

  The larger section 352 of the bottom rail has a slightly arcuate body 364 with a protruding edge 366 at its upper end and one beaded edge of the hinge element 356 adjacent to the protruding edge. A raised mounting element 368 having an open groove 370 adapted to receive the shaft 358 for axial rotation. The opposite or lower end 372 of the larger section is curved and spaced from the raised element 374 with a generally T-shaped cross section, so that a pocket 376 is formed between them, In it, the lower edge of the panel dummy strip 350 is secured, as shown in FIG. 59c. The lower edge of the dummy strip is wrapped around the fixed strip 378 and inserted into a pocket 376 formed between the curved end of the larger rail section and the raised T-shaped element. . An alternative fixture dummy strip shown in FIG. 59b is wrapped around the curved end 372 of the larger bottom rail section and stretched across the face of the arcuate body 364 and its upper edge 366. After being wrapped around, it can be fixed there with an adhesive. In any case, regardless of whether the support structure is fixed as shown in FIG. 59c or 59b, the support structure is fixed to the lower edge of the larger compartment.

  A second pocket 382 is formed between the T-shaped element 374 and the mounting element 368 and receives the end cap rib 384 of the bottom rail 340 inserted into this pocket, as shown in FIG. 59d.

  A lower section 354 of the bottom rail is depicted above the larger section 352 in FIGS. 59b and 59c and has a concave body 386 and a lower edge 388, which is the lower edge. The bead-like portion 358 provided along the edge of the hinge element 356 opposite to the edge attached to the larger compartment is rotatably received and held. An open groove 390 is formed. The upper or opposite edge 392 of the smaller bottom rail section is curved, forming a pocket 394 between the raised rib 396 on the concave body and the curved edge 392 of the smaller section. Yes. The pocket is adapted to receive and hold the lower edge of the support structure 326, which lower edge of the rigid or semi-rigid fixed strip 398 disposed within the pocket. It is wrapped around.

  As can be seen from the above, the operating element 312 is operatively secured to the lower edge of the larger section of the bottom rail through the dummy vane 350, as shown in FIGS. 59b and 59c. Structure 326 is fixed to the upper edge of the smaller or upper section of the bottom rail, as shown in FIGS. 59b and 59c, and the two sections of the bottom rail are hinged so that they can pivot about each other. Has been.

  FIG. 59d shows an exploded view of the larger section 352 and the smaller section 354 of the bottom rail, and at the same time, the hinge element 356 disposed between them and the aesthetic appearance and hinge element. And an end attached to the larger and smaller bottom rail sections provided to confine the support structure and the fixing strip used to secure the dummy vanes to the extruded section of the bottom rail. Cap 386 is shown.

  FIG. 61 shows the bottom rail 340 suspended from the lower edge of the panel 322 just before the panel extends fully from the roll bar 336. 62, 62a, 62b, 62c show that when the panel is moved from the retracted position wrapped around the roll bar to the fully extended position, the bottom rail supports the support structure 326 and the dummy vane 350, and the roll. It is an action | operation figure which shows how it cooperates with a bar.

  62, the panel 322 is substantially fully extended, and as can be seen, the larger section 352 and the smaller section 354 of the bottom rail 340 are aligned vertically. Yes. The groove 348 in the roll bar in which the operating element 312 is fixed is on the left side of the roll bar or roller 336, the groove 346 in which the support structure 326 is fixed is on the right side of the roller, and the support structure 326 is on the roller. Note also that it is wrapped around the top. FIG. 62a shows the roller rotating a quarter turn counterclockwise, with the bottom rail lowered to the bottom and adjacent to the window or other building opening frame to which the cover is attached. Yes. In FIG. 62b, the roller has made a further quarter turn in the counterclockwise direction, and as can be seen, the groove 348 in which the operating element is fixed is now on the right side of the roller, with the operating element facing upwards. To pull up the dummy vane 350 connected to the lower end of the operating element, so that the lower edge of the bottom rail as the upper edge of the bottom rail continues to move downward with the support structure 326. Department is raised. This movement moves the bottom edge of the bottom rail forward as seen in FIG. 62b. As the roller continues to turn counterclockwise, the groove 348 in which the operating element is secured moves to the top of the roller, pulling the operating element and, along with it, the bottom edge of the bottom rail 340, At the same time, as the groove 346 in the roller to which the support structure is connected moves from the left side of the roller to the bottom of the roller as shown in FIG. 62c, the support structure continues to move downward. In this position, as you can see, the place where it was originally the upper edge of the bottom rail has come down to a position close to the frame of the building opening, while keeping the entire bottom rail close to the frame, The bottom edge of the bottom rail is raised. In this process, each slat 324 is moved to a raised position, that is, an open position, so that a gap 402 is formed between the slats, and light and field of view pass therethrough. Panel 322 is shown in an isometric view in FIG. 62d and in the same position as taken in FIG. 62c.

  63-63d shows an apparatus for a cover of the present invention in which the bottom rail is modified from a bottom rail of two compartments to a bottom rail 404 having three or more compartments, in the example shown, five components 406. Is shown. As can be seen in FIGS. 63a and 63b, in this bottom rail device, as can be seen, there are five bottom rail components 406 interconnected in the same axially rotatable manner, each component 406 having an arcuate crossing. It has a face body 408 and, on the recessed side of the component, inward lips 410 and 412 along the top and bottom longitudinal edges, respectively. Of course, the components are elongated and extend the full width of the window cover. The lip of each component is either a dummy strip 350 that moves in synchronism with the operating element 312 in cooperation with the concave body portion of the component, or a support structure 326 disclosed as a sheet of thin fabric material. A pocket 414 is formed that extends to the full width of the component to receive a securing strip 416 that serves to secure either.

  The dummy strip 350 that moves in synchronization with the operating element 312 has a lower portion fixed to the three upper components 406 of the bottom rail 404, as can be seen in FIG. 63a. As can be seen, the flexible dummy strip extends downwardly from its connection to the lower edge of the lowest vane 324 of the cover panel 322, and the uppermost rail component. Is wrapped around the upper lip 410 of the upper rail, and then extends downward and is wrapped around the lower lip 412 of the uppermost rail component. The dummy strip is held in position by a rigid or semi-rigid fixed strip 416 disposed in a pocket 414 formed on the recessed side of the component. The dummy strip then extends downward and wraps around the upper lip 410 of the second tallest rail component 406, followed by wrapping around the lower lip 412 of the second tallest rail component. And is held in place by another securing strip 416 located within the pocket 414 of the second highest rail component. The dummy strip extends around the upper lip 410 of the third tallest rail component, again in place by the fixed strip 416 located in the pocket 414 of the third tallest rail component. Retained.

  The covering thin fabric or support structure 326 extends downward to the bottom edge of the bottom rail, where it is secured by a fixed strip 416 disposed in the pocket 414 on the recessed side of the bottom rail component. Retained in the lowest rail component 406. The support structure is then stretched upward and wrapped around the upper lip of the lowest rail component and subsequently wrapped around the lower lip 412 of the second lowest rail component. Thereafter, the support structure extends upwardly around the upper lip 410 of the second lowest component and is again held in place within the second lower component by the securing strip 416. The support sheet is then wrapped around the lower lip 412 of the third tallest component described above and held in place within the third tallest component by the fixed strip 416.

  The operation of the cover with the bottom rail shown in FIGS. 63, 63a and 63b is shown in FIGS. 63c and 63d. In FIG. 63c, the cover panel 322 is lowered to the bottom as shown to secure the actuating component 312 and thus the groove 348 in the roller associated with the dummy strip 350 causes the roller to bend back. As it rotates clockwise, it is moved to the right side of the roller. This movement raises the lower edge of the bottom rail 404 and, at the same time, the upper edge of the bottom rail is connected to the support structure 326 and continues to fall, and the groove 346 in which the support structure is fixed is a roller. Come to the left of If the roller is continuously rotated counterclockwise, the support structure will fall further as its support groove 346 moves to the bottom of the roller, while the groove 348 securing the operating element is on the right side of the roller. To the top of the roller to further raise the bottom edge of the bottom rail so that the bottom rail is substantially channel-shaped in cross section, as shown in FIG. 63d. Further, in this process, the lower edge of the blade 324 is pulled up as described above, so that a gap 402 is created between the blades as shown in FIG. 63d.

  Yet another embodiment of a bottom rail for use with the cover described above in FIGS. 62-62d is shown in FIGS. 64-64d. In FIG. 64, the cover panel 322 is fully extended as shown, but the vane 324 is in a closed position and a bottom rail 418 having a channel-type body 420 that is open upward is It is suspended just below. The elongated roller 422 is supported in a channel-type body so as to be able to rotate therein, and has a dummy strip member 350 wound around the rear surface of the panel. The free end is attached to the rear surface of support structure 326, which in the disclosed embodiment is a sheet of thin fabric. The operation of the cover with this bottom rail embodiment is shown in FIGS. 64c and 64d. In FIG. 64c, the groove 348 of the roller 336, which secures the operating element 346 and thus operatively connected to the dummy strip, is counterclockwise until the groove comes to the right side of the roller and the operating element begins to be pulled up. It is rotated in the turning direction. As the operating element is pulled up, the thin fabric support structure 326 continues to fall because its mounting groove 346 to the roller 336 is on the left side of the roller and moves downward as the right side of the roller moves upward. Therefore, since the dummy strip material moves with the operating element, when the operating element is pulled upward, the front portion of the dummy strip is pulled upward, while the back portion of the dummy strip material connected to the support structure. Moves downward with the support structure. In FIG. 64d, the groove 348 securing the operating element has moved to the top of the roller, raising the bottom edge of the vane 324 to the maximum, creating a gap 402 between the vanes. Since the dummy strip wrapped around the roller 422 in the bottom rail simply rotates with the roller in the bottom rail body 420, the bottom rail is the building opening to which the cover is attached. Stays at the lowest position adjacent to the frame. As will be appreciated by those skilled in the art, the bottom rail is not necessarily a roller, as it may work well with fixed surfaces that are preferably curved to provide a smooth sliding surface for the dummy strip. Also good.

  As shown in FIG. 65, a heavy rod or other element 423 can be attached to the panel 322 at a spaced apart position, for example, above the bottom edge 425 of the panel. The weight is sufficient to facilitate the desired suspension of the panel from the head rail (not shown) while providing some resistance to pulling the lower edge of the vane 324 with the operating element 346. Note that the bottom rail is not necessarily required. For example, as shown, the pocket 427 may be formed of the same material as the vane itself inside the vane that is spaced upward from the bottom edge of the panel. The pocket may be disposed so as not to be seen inside the blade, and an elongated rod 423 having an appropriate weight may be enclosed in the pocket. In this way, when the panel is unrolled from the roll bar, the weight of the rod encourages the panel to hang vertically, and the rod is enclosed in a slat adjacent to the bottom edge of the slat. Thus, when the operating element is lifted to open the vane by pulling up the lower edge of the vane, the rod provides some resistance to opening the vane, When the operating element is lowered while moving toward the closed position, it assists in lowering the bottom edge of the vane. The exact weight of such a rod or element 423 is within the skill of one of ordinary skill in the art and, of course, is selected so that the cover can be actuated as described above. Since the heavy rod is placed near the bottom of the panel 322, a short length of panel material is suspended under the heavy rod, and this short amount of material is suspended vertically. No need for heavy elements to maintain

  As previously mentioned, the cover hardware of the present invention includes a head rail 328 having an end cap 330 for supporting a blindfold plate 332. The end cap further supports the roller or roll bar 336 in a conventional manner so that the endless control cord 338 can be rotated in the reverse direction about its longitudinal axis. The adjustable stop 344 described above engages with the bottom rail 340 of the cover when the cover is retracted, so that the roll bar 336 can be prevented from rotating when the cover is fully retracted. Can be attached to the end cap at any of the different positions. The cover panel 322 can be any of a variety of lengths depending on the size of the building opening to which the cover is attached, so that the cumulative length of the panel on the roller changes, thereby filling the cover. The effective diameter of the roller in the head rail when drawn into the head rail also changes directly. In other words, the longer the panel is, the larger the effective diameter is when the panel is wound around the roller at the position where the cover is fully retracted.

  As can be seen in the drawing, the stopper 344 used in the cover of the present invention to limit the retraction of the roller 366 in the clockwise direction so that it engages the bottom rail 340 along the bottom of the panel 322. Since the radius of the panel material stacked on the roller varies depending on the length of the panel, the position of the bottom rail 340 when the bottom rail 340 enters the head rail 328 in the position where the cover is fully retracted. Will also change. Therefore, it is necessary that the stopper 344 can be positioned at different radial distances from the rotation axis of the roller 336. As best seen in FIGS. 58a and 58b, an adjustable stop 344 is provided for each of the three end caps 330 on the head rail to accommodate different positions as the bottom rail enters the head rail. It can be placed in any of the different openings or seat sets 424. The stopper can also be stored in either of the two pairs of openings in either of two positions, so that the stopper stored by the system of the present invention has six different positions. There is.

  First, in FIG. 58b, as shown, the stopper 344 has a bottom edge 428 that is somewhat recessed and is spaced two pairs of vertically spaced from the opposite sides 432 of the body in opposite directions. A block-shaped body 426 with aligned arms 430 is included. Each pair of upper arms 434 has a catch 436 at its end. Each pair of arms 430 is disposed closer to one edge 438 of the body 426 than the opposite edge 438, which changes the position of the stopper in the manner described below.

  Each end cap 330 has a stop element insert 442 that includes three sets of openings or seats 424. Each set of openings has an upper passage 444 and a lower passage 446 that are vertically aligned, each pair of upper passages passing through the top of the end cap 330. 448 is in communication. Each pair of passages is adapted to receive a pair of arms 430 of the stopper, and the upper arm catch 436 is within a vertical opening 448 associated with the pair of passages in which the stoppers are disposed. , To be releasably captured.

  Thus, as can be seen, for example, as can be seen in FIG. 58b, with the stopper 344 oriented in one direction, the pair of arms 430 on the left side of the stopper is inserted into any of the three sets of openings 424 and the upper side The arm catch 436 can be releasably held therein. Each set of openings corresponds to different length panels stacked on the roller, with the concave bottom edge 428 of the stopper body 426 disposed at different radial distances from the axis of rotation of the roller 336. By turning the stoppers in the opposite direction, a pair of arms on the stopper protruding from the opposite surface can be inserted into one of the three sets of openings, but both pairs of arms Is positioned closer to one edge 438 than the opposite edge 438, so that the concave lower edge of the body is positioned when the other set of arms are positioned in one of the passages. Will be placed in different positions. Thus, for the concave bottom edge 428 of the stopper element by directing the stopper element in one of the two orientations and inserting it into one of the three sets of passages in the end cap. Six different locations can be created to engage the bottom rail of the cover in the fully retracted position. Of course, the concave bottom edge of the stopper element is relatively wide so that each position itself naturally accommodates various effective radii of the roller around which a panel having a length within a given range is wound. To do.

  Another embodiment of the cover of the present invention is shown in FIGS. 66-84. This embodiment uses a panel 450 similar to that shown in FIGS. 57-64, and the support structure 452 is shown by way of example as a sheet of thin fabric material, with a plurality of two A heavy-loop working blade 454 is supported. The vane has an inner loop 456 and an outer loop 458, both loops adjoining at the upper edge 460 and the bottom edge 462 of the vane, and the upper edge of each vane is a thin cloth. Further, it is fixed with an adhesive or the like along the horizontal line 464 of the mounting portion. Each blade is attached at a predetermined interval from an adjacent blade. A plurality of operating elements 466, shown by way of example in the form of microfilaments, etc., extend vertically along the front surface of the thin fabric and along their length at equally spaced locations, It is fixed to the bottom edge 462 of each vane plate, while allowing the upper edge portion 460 of each vane plate to slide freely through a gap (not shown) provided in a line 464 that attaches to a thin cloth. It has become.

  The upper end of the operating element and the upper edge of the thin fabric are fixed in opposite grooves 468 and 470 of the roller 472, as will be described later. The operating element 466 can be raised and lowered with respect to the thin cloth during the operation of the shade. When the operating element is pulled up with respect to the thin cloth 452, the operating element lifts the lower edge 462 of each blade. With respect to the upper edge portion 460, the blades are pulled up until they reach the open position of FIG. 66 and the upper edge portion and the bottom edge portion of each blade plate are close to each other. Of course, if the operating element is moved in reverse, that is, downward, with respect to the thin cloth, the bottom edge of each blade can be dropped with respect to the top edge until the blade is in the closed position. In this case, the blades extend in the vertical direction, overlap with the thin cloth, and slightly overlap with the adjacent blades, so that the field of view and light cannot pass through the shade.

  As best seen in FIG. 76, the lowest working vane 454 directly above the non-acting dummy vane 474 at the bottom of the shade has a bar 476 that weighs along its lower edge. Therefore, when the operating element 466 is moved downward with respect to the thin cloth, the heavy bar pulls the lower edge of the lowermost blade plate downward due to gravity, and at that time, Since the lower edge portions are fixed to the operating elements at positions spaced along the length thereof, the lower edge portions of the upper blades are simultaneously pulled downward.

  The non-actuating dummy slats 474 are simply loops made of the same material as the operative slats, with the top edge secured to the front of the thin fabric 452 and the bottom edge secured to the bottom rail 478.

  As can be seen by looking at FIGS. 67-69, the bottom rail 478 is generally U-shaped and is connected to the lower edge of the thin fabric 452 and the lower edge of the dummy vane 474. . As can be seen, the bottom rail has an arcuate front wall 480 and two legs 482 projecting rearward and spaced vertically, the legs having a rear edge thereof. It is hooked along portion 484 and cooperates with the front wall to form a channel 486 therebetween. In addition, pockets 488 are formed on the outer surfaces of both legs that are spaced apart above and below. The leg has an inwardly projecting bead 490 that forms a mouth into the channel 486.

  The lower edge of the thin cloth 452 is wrapped around the upper fixing bar 492 inserted into the pocket 488 on the upper leg 482, and the lower edge of the dummy blade 474 is the lower leg Is wound around a lower fixing bar 494 seated in the pocket 488. The central channel 486 forms a seat within which one or more slidably adjustable ballast bars 496 known by those skilled in the art can be placed. In the present disclosure, the ballast bar has fingers 498 that are circular in cross section and project from the rear surface, and the ballast bar is axially determined along the length of the channel by grasping the fingers with a hand. It is drawn so that it can be moved between different positions. The ballast bar is used to adjust the weight distribution of the shade so that the bottom rail is always placed horizontally and therefore the shade wraps smoothly on the roller.

  The roller 472 is rotatably attached to the head rail 500 (FIG. 71) in a conventional manner, the head rail being an arcuate front wall that terminates in a bottom edge 504 projecting rearwardly in a fork shape. 502 and an upper wall 506 having a recess 508 that is open to the rear immediately below, so that the end cap 510 can be fixed to the recess 508. The roller is rotated in one direction or the other in a conventional manner by a control code 512 shown in FIG.

  In FIG. 71, the shade is in the fully retracted position, the panel 450 is wrapped around the roller 472, and the bottom rail 478 is suspended from it, but the head rail 500 is shown for beauty. It shows a state of being trapped inside. The lower fork-like edge 504 on the front wall of the head rail has a clip 514 connected to the upper leg 516 of the fork, the clip being a decorative head rail cover such as a cloth material. The lower edge of the seat 518 is fixed to the lower leg 520 of the fork. The upper edge 522 of the cover sheet 518 is secured to the top wall 506 of the head rail with an adhesive or otherwise.

  Clip 514 forms part of the limiter system and is an elongated, preferably extruded element, catch plate 524 that extends diagonally and tilts upward and back as shown in FIG. And an upper arm 526 and a lower arm 528 extending horizontally from the lower portion of the catch plate. The upper arm has a downwardly facing lip 530 that can be connected to a wall 532 facing the front of the fork-like upper leg 516, the lower arm being connected to the lower edge of the fabric cover 518 It has a return lip 534 that engages and secures it in place. Therefore, as shown in FIG. 71, the clip can be releasably secured to the lower edge of the head rail with the catch plate 524 protruding upward and rearward for purposes described below.

The operation of the shade is shown in FIGS. 71 and 76-80, and FIG. 76 shows the shade starting to unwind counterclockwise from the roller in the head rail 500. FIG. The bottom rail 478 is relatively heavy in relation to the fabric panel 450 and falls by gravity when the roller is turned, and of course the rotation can be stopped in any conventional manner by the control code 512. As described above, the thin cloth 452 is fixed in one groove 470 of the roller 472 by the fixing rod 538, and the upper end of the operating element is diametrically opposed by the fixing rod 538. Since it is fixed in 468, when the blind approaches the fully extended position (FIG. 77), the groove 470 to which the thin fabric is attached is located at the top of the roller and the operating element is fixed. The groove 468 is located at the bottom of the roller. As best seen in FIGS. 72 and 77-80, the catch bar 540 is secured to the front surface of the thin fabric 452 in the horizontal direction, just above the upper edge of the uppermost vane 454 of the panel 450. The attachment can be done by adhesive, ultrasonic bonding, or other suitable method. The catch bar, as best seen in FIG. 72, has a vertical backplate 542 secured to a thin fabric 452 and a plurality of downwardly facing forwardly elongated fingers 544 that are spaced from one another. 545 is arranged, and the space forms a path through which the selected operation element 466 passes slidably. The finger 544 overlaps with the catch plate 524 in the vertical direction for the purpose described later. A reinforcing strip 546 of some rigid or semi-rigid material holds the catch bar upright and helps to align it vertically with the catch plate 524 and is secured to the opposite side of the thin fabric to the catch bar It is desirable.

  An alternative to the limiter system having the catch bar 540 shown in FIG. 72 is shown in FIGS. 73-75, which shows one of the plurality of flat bars 546, which is Can be secured to the thin fabric with punch tabs 548 forming fingers projecting forward at spaced locations along its length, to cooperate with the catch plate 524 as will be described hereinafter. It has become. A plurality of bars 546 are provided so that the operating element can pass between the punch tabs. FIG. 74 shows another embodiment 550 in which a notch 553 is cut into the gap between the fingers 554 along the lower edge of the back plate 552 to confine the operating element therein. It is very similar to the embodiment of FIG. 71 except that it is kept in the gap between adjacent fingers. FIG. 75 shows yet another device, with a plurality of inverted V-shaped members 556 having a back plate 558 that can be secured to a thin fabric and fingers 560 that project forward and downward. The operation element is slidably passed between the connection positions of the respective members 556 to the thin cloth.

  In FIG. 77, the shade is in a position where the catch 540 will soon overlap the catch plate 524 of the clip 514, so that when the roller rotates further counterclockwise, the catch falls onto the catch plate (FIG. 78) And the thin cloth 452 connected thereto is prevented from moving further downward. When this happens, the roller groove 468 securing the operating element 466 rotates further away from the catch plate, so that the operating element begins to be pulled, so that the operating element moves to the lower edge 462 of the vane. Since it is connected, the lower edge of the vane begins to rise. When the roller is further rotated counterclockwise, the upper edge of the operating element is further pulled away from the catch plate, as shown in FIG. As shown in FIG. 80, the shade is fully extended, and the blade is fully opened at the extreme position of the roller. As can be seen in FIGS. 78-80, as the operating element pulls up the lower edge of the vane, excess thin fabric 452 is gathered out of view in the head rail. The rest of the thin fabric is stationary, as described above, and the bottom rail 478 is preferably adjacent to the window frame or bottom edge of the building opening to which the shade is attached.

An alternative limiter system is shown schematically in FIGS. 93 and 94, where the hook bar 560 is in the shade head rail 500 opposite the back of the thin fabric 452, ie, the operating element 466 and the vane 454. Attached adjacent to the side. The hook bar is made of any suitable rigid or semi-rigid material, such as metal or plastic, and is supported in the head rail in any suitable manner. The hook bar has a vertical body 562 and a lower lip 564 that is forward-facing and inclined upwards, so that the clip 568 attached in place on the back of the thin fabric can be captured or released. A notch 566 is formed that is adapted to receive. The clip may also be made of a suitable material, such as metal or plastic, and is essentially rigid or semi-rigid. Reinforcement strips (not shown) are attached to the opposite side of the fabric, i.e., in front of the clip and aligned with the clip to enhance the attachment of the clip to the fabric so that the clip is maintained in the desired orientation as shown. May be. In FIG. 93, the shade is approaching its fully expanded state, but before the vane is opened with the operating element. As the roller continues to rotate counterclockwise as shown in FIG. 94, the clip falls into the hook bar notch 566, which prevents the thin fabric from moving further downward and is associated with other limiter systems. As described above, the operating element opens the vane.

  95 and 96 schematically illustrate yet another alternative of the limiter system, in which a support bar 570 is placed in the head rail 500 in some suitable manner, with a thin fabric 452, vane plate 454. And it is attached at a position immediately adjacent to the rear side opposite to the operation element 466. The support bar has a horizontal recess along its lower edge, to which a magnet 572 is fixed at a position immediately adjacent to the rear surface of the thin fabric. A horizontal metal strip 574 is fixed at a predetermined position on the rear surface of the thin cloth, and when the metal strip on the thin cloth passes, the metal strip is attracted to the magnet and is releasably attached. It comes to stick. In FIG. 95, the shade is in a position immediately before being fully deployed, but the blade is closed. In FIG. 96, the shade roller 472 is turned a small distance in the counterclockwise direction, the metal strip is aligned with the magnet, and they are attracted and releasably stuck. Of course, this limits or inhibits the thin fabric from moving further downwards, so that if the roller is further turned counterclockwise, the operating element lifts the vane to its open position, as described above. be able to. The support bar is adjustably mounted in the head rail to ensure that the magnet is closely adjacent to the metal strip when the shade reaches its fully extended position, but the system for mounting the holder Is within the skill of one of ordinary skill in the art and need not be described.

  97 and 98 show another alternative of the shade limiter system of the present invention. In this alternative, the fork-like lower edge 532 of the head rail 500 is adapted to receive the anchor 576 in the space between the fork-like fingers, which anchor has a vertical plate portion 578. On the vertical surface behind it. T.A. M.M. A strip of loop material is affixed. On the front of the thin cloth 452, Velcro R. T.A. M.M. The hook material is attached at a position immediately above the uppermost blade 454 so that the loop material on the anchor can be grasped when the hook material approaches the loop material when the shade is deployed. It is desirable that a plurality (not shown) of hook material strips 582 are arranged at intervals in the horizontal direction, and a space for moving the operation element 466 is formed therebetween. When the shade is fully extended, as shown in FIG. 98, the hook material is aligned with the loop material, and when the roller 472 is rotated counterclockwise by the operating element, the operating element is Because the hook material is pulled forward in the hook material, the hook material is actually pulled to engage the loop material. Of course, when the roller is rotated clockwise to retract the shade, the hook material and the loop material are disengaged, and as you can see, there is no effect on the operation of the limiter system. And the loop material may be reversed.

  FIGS. 99-101 show another limiter system in which the roller 584 is modified from the previously described apparatus by providing an arcuate depression 586 covering its circumference about 180 degrees along its length. ing. An arcuate bracket 588 having three spaced arcuate bands 590 of a rigid or semi-rigid structure, as shown in FIG. It is fixed adjacent to the end. As best seen in FIGS. 100 and 101, the band cooperates with the arcuate groove of the roller to form an arcuate track 593 that carries a support rod 594 secured to the upper edge of the thin fabric 452; The thin fabric is formed with a slot 596 for passing an arcuate band. As can be seen in FIG. 100, when the shade is pulled up and rotated clockwise (not shown), the rod is in the lower end of the track 593 so that the roller is rotated clockwise. During this time, the shade is wrapped around the outer surface of the roller and band. However, when the shade is unwound, as shown in FIGS. 100 and 101, the roller rotates counterclockwise so that the support rod 594 is operated by the roller lifting the blade 454 to the open position. As element 466 is pulled forward, it rises in the track. As can be seen, the track is equidistant from the lower edge of the head rail 500 when the operating element is lifted, so that the thin fabric is prevented from falling and the operating element opens the slats. Can be lifted into position.

  Yet another embodiment of the cover of the present invention is shown in FIGS. This embodiment also uses a panel 450 similar to that shown in FIGS. 57-64, and the support structure 452 is, by way of example, a thin support that supports a plurality of double loop actuating vanes 454 on the front surface. Shown as fabric sheet material. The vane has an inner loop 456 and an outer loop 458, both of which are connected by an upper edge 460 and a bottom edge 462 of the vane. Thus, it is fixed to the thin cloth along the horizontal line 464 of the attachment. Each blade is attached at a predetermined interval from the adjacent blade. A plurality of operating elements 466, shown by way of example in the form of microfilaments, extend vertically along the front of the thin fabric and are equally spaced along the length of each vane. It is fixed to the bottom edge portion 462, and can freely slide through a gap (not shown) provided in an attachment line 464 to the thin cloth of the upper edge portion 460 of each blade.

  The upper end of the operating element and the upper edge of the thin fabric are fixed in grooves 468 and 470, respectively, on the opposite side of the roller, as will be explained later. The operating element 466 can be moved up and down with respect to the thin cloth during the operation of the shade. When the operating element is lifted with respect to the thin cloth 452, the operating element is moved to the lower edge of each blade. With the portion 462 facing the upper edge 460, the blades are in the open position of FIG. 115 and are pulled up until the top and bottom edges of each blade are closely adjacent to each other. Of course, if the operating element is moved backwards, i.e. downwards, with respect to the thin fabric, the bottom edge of each vane will be in the closed position with respect to the upper edge, and will be stretched vertically and thinned. It falls until it overlaps the fabric and slightly overlaps the adjacent slats, blocking the field of view and light passage through the shade.

  As best seen in FIG. 109, the lowest working vane 454 directly above the inoperative dummy vane 474 at the bottom of the shade has a bar 476 that weighs along its lower edge. Therefore, when the operating element 466 is moved downward with respect to the thin cloth, the heavy bar pulls the lower edge of the lowermost slat downward by gravity, with each bottom of the slat Since the side edge is fixed to the operating element at a position spaced along the length thereof, the lower edge of each upper blade is simultaneously pulled downward.

  The inoperative dummy slat 474 is simply a loop, preferably made of the same material as the operative slat, with its upper edge secured to the front of the thin fabric 452 and its bottom edge secured to the bottom rail 478. Yes.

  The bottom rail 478 is substantially U-shaped and is connected to the lower edge of the thin cloth 452 and the lower edge of the dummy vane plate 474, as can be seen from FIGS. 103 and 109. As can be seen, the bottom rail has an arcuate front wall 480 and a leg 482 protruding rearward and spaced vertically, the leg 482 having a rear edge thereof. It is hooked along 484 and cooperates with the front wall to form a channel 486 therebetween. Further, pockets 488 are formed on the outer surfaces of both the upper and lower legs that are spaced apart. The leg has an inwardly projecting bead 490 that forms a mouth into the channel 486.

  The lower edge of the thin fabric 452 is wrapped around the upper fixing bar 492 inserted into the pocket 488 of the upper leg 482, and the lower edge of the dummy vane 474 is the lower leg pocket 488. It is wound around a lower fixed bar 494 disposed inside. The central channel 486 forms a seat in which one or more slidably adjustable ballast bars 496 known by those skilled in the art can be placed. The ballast bar is used to adjust the weight distribution of the shade so that the bottom rail is always placed horizontally, so that the shade wraps smoothly around the roller.

  The roller 472 is rotatably mounted in the head rail in a conventional manner as shown in FIGS. 103 and 109, and the head rail can be seen in FIGS. It has an upper wall 622, a rear wall 624, and an end cap 625.

  The upper wall 622 is supported by a mounting bracket for mounting the head rail to the building opening, as described above. The top wall includes a groove 626 along the front edge and releasably receives a tongue 628 along the top edge of the front wall 620. The front wall is a concave arcuate wall at the rear, and has a bottom edge portion 630 that protrudes rearward in a fork shape. The top wall further has a groove 632 adjacent the trailing edge to releasably receive a tongue 634 along the top edge of the rear wall 624. The bottom edge of the rear wall forms a hook-shaped catch 636 that opens upward for the purposes described below. As can be seen, the rear wall is also arcuate in cross section and concave forward. The lower edge 636 extends forward and downward. The three components of the head rail are extruded parts, all made of aluminum, plastic, etc., and the front wall may be covered with a cloth material 638, for example, so that it looks beautiful if necessary.

  The catch 636 cooperates with a catch plate or extruded part 640 that is incorporated in or secured to the thin fabric 452 at a short distance downward from the connection to the roller 472 at the upper edge of the thin fabric. Work. In the present disclosure, this short distance is about half the circumference of the roller. The catch plate, as best seen in FIGS. 108-115, is an extruded plate-like member having an arcuate cross-section and opens upwardly between the lips 644 facing each other adjacent the bottom edge. , A downwardly opening groove 646 forming a catch lip 648 immediately above the groove 642, and a hook-shaped upper edge 650. It will be apparent that the catch plate will rotate with the roller until it separates from the roller near the end of the counterclockwise rotation of the roller, as will become apparent below. References to various locations assume catch plate arrangements that appear in various drawings. The third fixing bar 652 wraps the thin cloth partially around the third fixing bar, and inserts the third fixing bar into the groove 642 that opens upward, thereby making the catch plate into the thin cloth. Used for mounting. The catch plate's arcuate curvature coincides with the generally cylindrical outer surface of the roller, so that the catch plate can move around the roller generally along the support structure when the cover is fully retracted, for example, as shown in FIG. Wrapped around.

  As the cover is unrolled, the roller 472 is moved counterclockwise as shown in sequence from the fully retracted position of FIG. 103 to the fully extended position of FIG. Due to the weight, gravity first falls through the position shown in FIG. 109, so that the thin fabric 452 and the operating element 466 begin to unwind from the roller. FIG. 110 shows a cover with a thin fabric wrapped slightly more than the last roll around the roller, and in FIG. 111 after another turn, the thin fabric is partially wrapped around the top of the roller. The catch plate 640 is released from the roller while being attached to a thin cloth. As can be seen, in the position of FIG. 111, the catch lip 648 of the catch plate is over the catch 636 at the bottom edge of the head rail rear wall 624, so a thin fabric is shown in FIG. Further unwinding, the catch plate is lowered so that the catch lip of the catch plate moves into a closely adjacent relationship with the catch on the rear wall of the head rail. FIG. 113 shows the roller rotated a further distance in the counterclockwise direction, and the catch lip of the catch plate is inserted into the catch that opens upward on the rear wall. Since it is inserted into the groove 646, even if the roller continues to rotate counterclockwise, the catch plate does not move further downward. As can be seen from FIG. 113, the lower edge of the catch plate 640 in this position fills the gap between the lower edge of the rear wall and the lower edge of the front wall, and the operating element is A fork-like bottom edge 630 of the front wall is slidably engaged. If the roller continues to rotate in the counterclockwise direction as shown in FIG. 114, the thin cloth 452 is loosened above the catch plate in the head rail, and the operating element 466 has a fixed position with the roller. As the distance from the fork-shaped bottom edge of the front wall increases, it is pulled upward. FIG. 115 shows that the roller is in the fully unwound position and that the vanes 454 are in their fully open position by pulling the bottom edge 462 of each vane closer to the upper edge 460 of each vane. It shows the state of being moved.

  When the cover is rewound by rotating the roller in the clockwise direction, the operating element is first lowered, and the slats are moved from the open position in FIG. 115 to the closed position in FIG. And then the catch plate rises and departs from the catch relationship with the catch on the rear wall of the head rail. Next, the thin cloth lifts the catch plate to a position where it is complementary to the roller, and continues to rotate the roller clockwise, so that the thin cloth is rotated around the catch plate and the cover is fully moved to the position shown in FIG. Wrapped until pulled.

  81-83 only show a variation of the shade, the dummy vanes 474 can be made at different heights, with the highest height shown in FIG. 81 and the lowest height shown in FIG. ing. Changing the height of the dummy slats is to make the appearance beautiful, or in particular, the lowest slats of the slats 454 that are actuated are separated from the window frame by different distances, and the gaps are made with the dummy slats. This is because the shade length can be selected when filling. FIG. 84 is simply an enlarged view showing the overlap of the bottom edge of the lowest working blade 454 and the upper edge of the dummy blade 474, the lowest edge of the lowest working blade. A heavy bar 476 is attached to the part and the lower edge of the operating element 466 is secured thereto.

  The retraction movement of the roller, that is, the rotational movement in the clockwise direction, is limited by the contact stopper bracket 562 which can be seen well from FIGS. 85 to 91. The contact stopper bracket is attached to the head rail, and the shade is attached to the head. It is arranged to engage with the bottom rail 478 in place when the panel is fully retracted into the rail and the panel is wrapped around the roller 472. 86 and 91, the stopper bracket includes an attachment base 564 that can be fixed to the upper edge of the head rail 500, and a hanging stopper member 566 that is adjustably connected to the base 564. It has a two-part bracket.

  The base 564 includes a generally U-shaped body 568 formed by a bottom leg 570 and a pair of vertically extending side legs 572, the side legs being vertically oriented. Are spaced inwardly spaced inwardly spaced fingers 574 between which are formed channels 576 along each leg. The set of fingers includes a plurality of fingers along the upper edge of each side leg 572 and a plurality of fingers along the bottom edge of each side leg 572. The fingers are offset from each other. The catch arm 578 extends rearward from the bottom leg 570 so as to be arranged between the side legs in parallel and at equal intervals with each side leg. The catch arm has a length slightly shorter than the length of the side legs, but is preferably at least half the length of the side legs. The catch leg has a downwardly protruding lip 580 adjacent its rearmost edge. The catch arm is inherently somewhat flexible due to the nature of the material forming the stopper bracket. The material may be any suitable plastic, polyurethane, or even a metal that is somewhat stiff but somewhat flexible. The insert plate portion 582 of the base 564 extends forward from the bottom leg 570 of the base, and the insert plate is comprised of a generally rectangular material loop 584 that is approximately half the depth of the base body 568. And has a rectangular opening 586 formed in the center. A catch leg 588, one end of which is fixed to the front side of the bottom leg of the base body, projects forward into the rectangular opening, and the catch leg is the foremost as shown in FIG. It has a lip 590 protruding downward from the end. The catch legs are somewhat stiff but somewhat flexible due to the nature of the material from which the stopper bracket is made.

  The stopper member 566 has a substantially inverted L-shape, and is formed by a pair of parallel side rails 594 spaced apart by a washboard-like central portion 596. The washboard has an inclined tooth having a vertical leg 600 along the rear edge and an upper surface 602 that is inclined forward and downward and connected to the next adjacent tooth. 598 is included. The side rail thickness is such that it can slide within the channel 576 formed between the paired fingers 574 of the base body with almost no gap, and the lip 580 at the rear edge of the catch arm is The nail is placed in the space between the selected teeth.

  Thus, as can be appreciated, the upper horizontal leg 592 of the stopper member 566 is selectively confined within the base body 568 and inserted by the catch arm 578 to the selected depth into the base body. Held in the same position. The vertical leg 604 hangs downward from the rearmost edge of the horizontal leg 592 and terminates with a concave arcuate abutment 606 on the lower end thereof. The vertical leg has a reinforcing gusset 608 on the front surface that reinforces the vertical leg.

  As will be understood from the following description, the downwardly concave contact portion 606 is engaged with the bottom rail 478 of the shade when reaching the position where the shade is fully retracted, and the stopper member 566. And the base portion 564 of the stopper bracket, the contact portion can be appropriately positioned so as to engage with the bottom rail. As can be seen, the spacing of the bottom rail from the roller 472 depends on the length of the panel 450 of shade material and thus the thickness of the panel wrapped around the roller. Of course, the winding thickness determines the location of the bottom rail when the shade is fully retracted and the stopper member is positioned accordingly.

  In FIG. 92, as described above, the upper wall 506 of the head rail 500 protrudes in the horizontal direction. Since the upper wall overlaps the substantially parallel legs 610 formed on the head rail, a recess 508 is formed between the two. The horizontal leg 610 is formed with a cut 621 extending in the longitudinal direction and a catch 614 at the distal edge. The base insert plate portion 582 is adapted to be inserted into a recess 508 between the legs 610 parallel to the top edge of the head rail, and the lip 590 at the rear edge of the catch leg 588 is , And snap fits into cuts 612 formed in the parallel legs. The insertion plate is therefore releasably confined and secured in a recess formed in the head rail, thus providing the base body 568 with a receiving portion for the horizontal leg of the stopper member 566. ing.

  As can be understood from the above, when the stopper bracket 562 is properly attached to the head rail 500, the stopper bracket is disposed at a position where it abuts against the bottom rail 478 and restricts further movement, so that the shade is full. , Stops the clockwise rotation of the roller around which the fabric panel 450 is wound. Of course, the stopper bracket does not inhibit the counterclockwise rotation of the roller, so as previously described, the panel 450 can be easily unwound and deployed so that the panel extends completely over the building opening. However, the catch 540 may engage the catch plate 524 to limit further extension of the shade support structure.

  As will be appreciated by those skilled in the art, the cover according to the present invention can be subject to many modifications, some of which include a support sheet as a support structure, a plurality of vertically extending single fibers, tapes Or related to replacement with ribbons, natural or synthetic fiber cords and the like. Similarly, the operating element may be replaced by a single fiber, a strip or ribbon of material, a natural or synthetic fiber cord, and the like. Furthermore, the cross-sectional shape of the slats may vary so that it looks different, and the other cellular slats formed on opposite sides of the lift element and the operating element may be symmetrical in various shapes. However, the front element and the rear element may be asymmetric so as to have different shapes. Furthermore, the flexibility of the material from which the slats are made may be altered to achieve different aesthetics. When using a rigid or semi-rigid material, the crease that forms the fold line to achieve the desired functionality. Can also be formed in the material. By using the selected material, the permeability, as well as the color of the slats can be adjusted.

  Further, the slats have been disclosed to be connected to the support structure along the upper edge and the lower edge can be moved to move the cover between the open and closed positions. It may be. That is, the bottom edge of the slat may be fixed to the support structure and the top edge may be moved. Of course, the slat is attached in the vertical direction, one edge is fixed to the support structure, and the other is The blades may be moved between an open position and a closed position by moving toward or away from the edges of the blade.

  Although the present invention has been described with a certain degree of concreteness, the present disclosure has been given by way of example and without departing from the spirit of the invention as defined in the claims. It should be understood that the structure can be changed.
