Definitions

  • This invention relates to collapsible and expandable tubular structures, and more particularly to a curtain comprised of flexible strips made into tubular units by bands of adhering contact.
  • the tubular structure can be used as an insulating curtain over openings such as doors, windows and the like.
  • the invention also relates to the method of producing such curtains from continuous strips of thin-film material.
  • a beehive like wall structure with multiple cells for insulating purposes is illustrated in Finnish Patent No. 23939 dated May 31, 1950.
  • the structure is made by gluing thin plates of paper to each other and to outside surface boards at areas of contact on alternating sides of the plates.
  • the insulation board has relatively few cells in each row and those cells could be compressed and expanded only a few times without deterioration of the wall material.
  • the area of glued contact between adjacent plates must be limited to a maximum of 1/3 of the width of the air cell, presumably to minimize the severe distortion that would occur in the walls of the partial cells adjacent to each surface board. Since the width of the glued area is transverse to the direction in which insulation is desired, the air cells must be fully expanded for effective insulation.
  • tubular structure of the present invention which may have a plurality of insulating cavities both in the direction of curtain height and in the direction of curtain thickness. While the insulating properties of one tubular unit are significant, much better insulation can be provided by a plurality of tubular units across the curtain thickness. The insulating characteristics of those units are further enhanced by aligning the bands of adhering contact in the direction to be insulated. The insulating effectiveness of the tubular cavities is thereby maximized and does not change significantly with the degree of expansion.
  • the novel method disclosed for producing insulating curtains is much simpler and faster and more economical than heretofore known.
  • a plurality of curtains are simultaneously produced from strips of relatively inexpensive material.
  • the individual strips may be of any thin flexible material, and are preferably of thin film plastic. Although narrow relative to length, the strips may be many feet in width, the width being limited only by practical considerations of winding sheet material.
  • two or more strips are pulled simultaneously from multiple sources and each passed through a station at which adhesive is applied to one surface in multiple transversely spaced bands.
  • the bands are applied in a staggered relationship and the strips arranged adjacent to each other with an adhesive surface opposing a non-adhesive surface.
  • the bands are preferably of a substantially uniform width and spaced transversely from each other at substantially the same distance.
  • the width of each band corresponds to the desired width of the corresponding tubular unit in its expanded state. Accordingly, the sum of the width dimensions of all bands spaced transversely across two adjacent strips will equal approximately the overall thickness of the curtain when fully expanded.
  • the strips are interleaved and wound in superimposed layers about the periphery of a forming member so as to interlaminate adjacent strips and the bands of adhesive therebetween.
  • the staggered bands between successive strips produce tubular units formed with a lower wall from one layer and an upper wall from the next superimposed layer.
  • the upper and lower walls are adheringly secured together by bands of contact on opposite sides of the tubular cavity and each tube thus formed is adheringly secured to the next superimposed tube by a band of contact across a midsection of the upper tube wall.
  • the side bands and the mid band all extend longitudinally along each tube and define non-adhering sidewalls therebetween.
  • Tubular units so arranged will expand or open when stretched in a direction transverse to the plane of the strips.
  • a row refers to tubular units aligned with curtain height and not to successive units in the direction of curtain thickness.
  • the minimum number of transverse bands is 3, additional bands being spaced transversely depending upon the number of adjoining tube rows desired.
  • the number of layers wound upon the forming member is chosen to yield the desired number of tubes in each row, which in turn determines curtain height.
  • the interlamination of only two strips is also possible and will produce tubular units adjoined by bands of contact across the width of the strips.
  • the curtain may have successive tubular units adjoining in the direction of curtain height or in the direction of curtain thickness or in both directions, the latter being preferred.
  • the resulting stack of superimposed tubes is cut transversely, removed from the forming member, and straightened into a linear stack.
  • the length of the tubes is a multiple of the desired curtain width
  • a corresponding number of transverse cuts are made to produce multiple curtains.
  • a plurality of curtains can also be produced by one or more longitudinal cuts down the tube length.
  • the strips at the top and bottom of the stack may be pulled apart to expand the tubes.
  • the curtain is extended to its full height when the tubes are fully expanded.
  • the end strips may then be moved together to collapse one or more tubes.
  • the tubes collapse in accordion fashion along fold lines formed by the side bands of contact. When flattened, the height of the tube stack approximates the total thickness of the superimposed layers of film material.
  • one end may be secured to a mounting slat and the other to a second slat movable relative to the first.
  • Pull cords and other conventional hardware may be added to the slats to mount the curtain and selectively collapse and expand the tubular units in a manner similar to venetian blinds.
  • the tubular structure can be readily mounted, with or without supporting slats along the end strips, in a number of different positions for a wide variety of uses. It has wide utility as a thermal insulating curtain and when extended vertically can serve as a substitute for storm windows, storm doors and the like.
  • the curtain can be extended horizontally and pulled taut to serve as insulation beneath a floor or above a ceiling.
  • the individual tubes can be collapsed and expanded numerous times and provide a curtain having a long usable life. In its collapsed state, either as mounted or as removed for storage, the curtain folds into a stack of thin flat strips neatly aligned in a column.
  • Curtains of varying height can be made depending upon the number of strips superimposed upon the forming member. Multiple curtains of less height than originally formed can also be made by cutting the linear stack of tubes longitudinally in a direction transverse to curtain height.
  • the composition of the strip material may be selected to yield light admitting tubes (transparent or translucent), light absorbing tubes (black or other dark colors), or light reflecting tubes.
  • a pigment material may also be added to the adhesive used so that the bands of contact have similar light controlling characteristics. With light controlling bands, the degree of light admitted, absorbed or reflected can be controlled by tilting the upper and lower most strips by means of attached slats which will in turn produce a corresponding tilt of the longitudinally extending bands in a manner similar to the louvers or slats of a venetian blind. Similar light controlling characteristics can be obtained by applying appropriate coatings to one or more sections of each tube wall.
  • the tubular structure has many other applications, such as structural members for greenhouses and other buildings requiring the admission of large amounts of light and for modular structures utilizing flexible sheet material.
  • the tubular units may be reinforced internally and positioned on end as self-supporting walls, folding doors and other structural components.
  • the tubes may also be sealed and pressurized internally with air as structural members for air supported domes and the like.
  • FIG. 1 of the drawings One embodiment of the tubular curtain of the present invention, generally designated 10, is shown in Figure 1 of the drawings.
  • the curtain is comprised of a row of tubes Cl which are superimposed one atop the other in the direction of curtain height as best illustrated in Figures 1 and 7.
  • Each tube has the same structure as tube 12 which will be described in detail.
  • the tube 12 has an upper wall 14 and a lower wall 15, each wall having two longitudinally extending edges. The edges of one wall abut the corresponding edges of the other wall along bands of contact 16 and 17 on opposite sides of the tubular cavity.
  • the portions of each wall within the bands of contact 16 and 17 are adheringly secured together by appropriate means compatible with the wall material, preferably an adhesive.
  • upper wall 14 has two side sections 14a and 14c and a mid section 14b
  • lower wall 15 has two side sections 15a and 15c and a mid section 15b.
  • Tube 12 is superimposed atop an underlying tube 18 and adheringly secured thereto along a band of contact coextensive with lower mid section 15b.
  • An overlying tube 19 is superimposed atop tube 12 and adheringly secured thereto along a band of contact coextensive with upper mid section 14b.
  • curtain Cl can be hung directly by attachment of uppermost strip 21 to an overhead structure, it is preferably provided with a mounting slat 23 and a movable slat 24 of a much more rigid material, such as wood or metal.
  • the slats may be adjusted relative to each other for collapsing and expanding the curtain by means of a drawstring or pull cord 25 which passes through a series of apertures 26 in the slats and intervening tubes of the curtain.
  • the end of cord 25 is knotted or otherwise secured at 27 to slat 24 so that the latter can be selectively adjusted by manipulation of the cord.
  • Upper slat 23 can be used for mounting the curtain and pull cord 25 arranged for manipulation in the manner described below for the embodiment of Figure 3.
  • the length of the slats corresponds substantially to the width of the curtain and the width of the slats corresponds substantially to the width of the thin-film strips from which the curtain is made.
  • the full length and width of the strips are thereby sandwiched between the slats when the tubes are collapsed. Accordingly, when fully expanded, the transverse width of the tubes is substantially less than the width of the slat.
  • the side sections of each tube have a width of about one-half the width of mid sections such that the width of slats 23 and 24 is about twice that of the mid sections.
  • the side sections are approximately equal to the mid sections.
  • the row Cl as formed has loose upper ends 21a and 21c and loose lower ends may be cut off or used to secure the top and bottom of the curtain to slats 23 and 24, respectively.
  • the tubular cavities defined by the upper and lower tube walls contain essentially still or dead air since those walls prevent any transverse movement of air. Accordingly, where a high degree of thermal insulation is desired, the tubes should be made of an impermeable material of low heat conductivity. The tube material should also be sufficiently flexible for the tubes to fully expand under their own weight and the weight of lower slat 24 and of a durability allowing repeated flexure without cracking or other deterioration. A good grade of thin polyethylene or equivalent plastic sheeting will satisfy these requirements.
  • Each side of the tubular cavity is a composite of two side sections, one from the upper and the other from the lower tube wall.
  • the side bands joining those two sections form fold lines along each side of the tubular units making up the curtain.
  • the double wall thickness and the adhering material at the sideband juncture provide reinforcement of the tube structure at the point of greatest stress and wall flexure.
  • FIG. 2 Another embodiment of the invention is illustrated in Figures 2, 3 and 9, the overall structure being generally designated 30 and the curtain portion thereof C2.
  • Curtain C2 is comprised of a plurality of tube rows 31, 32, 33, 34 and 35, one adjoining the other in the direction of curtain thickness.
  • Each row is comprised of a plurality of superimposed tubes having the same structure as the tubes in row C1 of Figure 1.
  • the bands of adhering contact between superimposed strips have been assigned a designation corresponding to the bands of adhesive applied when making the curtain as described later with reference to Figure 4.
  • the superimposed tubes of row 31 are joined together by bands of contact Al, the tubes of row 32 by bands B2, the tubes of row 33 by bands A2, the tubes of row 34 by bands B3, and the tubes of row 35 by bands A3.
  • These bands form the mid sections of the corresponding tubes.
  • the upper and lower side sections of tubes 31 are joined together on opposite sides of each tubular cavity by bands of contact Bl and B2, the side sections of tubes 32 by bands Al and A2, the side sections of tubes 33 by bands B2 and B3, the side sections of tubes 34 by bands A2 and A3, and the side sections of tubes 35 by bands B3 and B4.
  • those bands intervening between the outer vertical walls 40 and 41 of curtain C2 serve both as a band of contact joining the side sections of the tubes in an adjacent row.
  • Bands inside of outer tube rows 31 and 35 join the side sections of two adjacent rows, one at each edge of the adjoining band.
  • band B2 adheringly secures superimposed tubes 32 one atop the other in the direction of curtain height and also adheringly secures the upper and lower side sections on one side of tubes 33.
  • the bands adjoining the side sections of each tube define fold lines for the collapse and expansion of that tube and the curtain as a whole. The tubes therefore collapse into a symmetrical stack S when compressed together as illustrated in Figure 3.
  • FIG 3 there is shown a pair of pull cords 50 and 60 and corresponding pulley mechanisms 51 and 61 for manipulating the multirow tubular curtain C2.
  • Pull cord 50 passes over a pulley 54 and down through a series of apertures 52 in a support slat 42, a movable slat 44 and the intervening tubes of center tube row 33.
  • the end of pull cord 50 is secured to the movable slat 44 by a knot 53 or other fastening means as seen in Figure 2.
  • Pulley 54 is rotatably mounted upon a shaft 55 supported by a pair of brackets 56-56 which may be secured to mounting slat 42 by screws 57 or the like.
  • pull cord 60 passes over a pulley 64 and through apertures 62 and is secured to movable slat 44 by knot 63.
  • Pulley 64 is rotatably mounted upon shaft 65 supported by a pair of brackets 66-66 which are secured to slat 42 by screws 67 or the like.
  • the slat 42 may be mounted in a window, doorway or other opening by means of eyebolts 68 or other mounting brackets which may be positioned at each corner of the mounting slat as illustrated in Figure 3.
  • Mounting eyebolts 68 cooperate with hooks or other cooperating fastners (not shown) as can be mounted along the top of a frame around the opening or on adjacent structure, such as a ceiling,
  • curtain C2 is preferably made without any adhering material on the upper surface of uppermost strip 38 or on the lowermost surface of lowermost strip 39. This leaves a series of unadhered upper sections 38a, 38b, 38c and 38d and unadhered lower sections 39a, 39b, 39c and 39d. These may be left along or cut as illustrated by the cut line K through the lower sections.
  • the end strips can be secured to the slats in the shape shown in Figure 9, it is preferable to attach those strips in a flattened state so that a neatly folded stack S will be produced when the curtain is collapsed.
  • the aide sections 38a and 38d and 39a and 39d are pulled transversely apart in the direction of curtain thickness causing the uppermost and lowermost tubes of rows 32 and 34 and some adjacent tubes to flatten as seen in areas D and D' of Figure 2.
  • the flattened upper and lower surfaces are then secured to the corresponding slats by an appropriate means of attachment, such as a layer of adhesive. Staples, nails and similar means of physical attachment can also be employed.
  • an appropriate means of attachment such as a layer of adhesive. Staples, nails and similar means of physical attachment can also be employed.
  • the width of the side sections and mid sections of each tube will again determine the width of the slats to be used with the curtain.
  • the slat width is, of course, also a function of the number of tube rows making up the curtain.
  • the number of rows and the section widths are chosen so that the collapsed thickness does not exceed twice the fully expanded thickness of the curtain.
  • the width of each side section should be about 1/2 the mid band width.
  • a first supply roll 80 and a second supply roll 90 provide continuous strips 82 and 92 of thin-film material, preferably thin sheets of plastic.
  • Strip 82 passes through an upper adhesive station A comprised of a guide roller 83 for tensioning and directing the strip over a series of applicator wheels Ml, M2, M3 and M4 mounted for rotation upon a shaft 85.
  • the applicator wheels M contact the underside of strip 82 and underlying those wheels is a pick-up roller 86 mounted for rotation partially submerged in an adhesive contained in a trough 88.
  • Strip 92 passes through a lower adhesive station B comprised of a guide roller 93 for tensioning and directing the strip over a series of applicator wheels N1, N2, N3, N4 and N5 mounted for rotation upon a shaft 95.
  • the applicator wheels N contact the underside of strip 92 and underlying those wheels is a pick-up roller 96 mounted for rotation partially submerged in an adhesive contained in a trough 98.
  • strip 92 is interleaved beneath strip 82 and the two strips wound simultaneously upon a forming member, generally designed F.
  • the supply rolls, the rollers and wheels of the adhesive stations, and the forming member are suitably mounted for rotation relative to each other, and that the forming member is driven by conventional machinery to wind the continuous guide strips 82 and 92 thereon in interleaved fashion.
  • Guide rollers 83 and 93 maintain sufficient tension on the strips to produce a flat even stack of superimposed strips around the periphery of the forming member.
  • the forming member is shown as a cylindrical drum 100 for purposes of illustration.
  • the forming member may take other shapes capable of providing a continuous winding surface about their periphery.
  • the member may be comprised of an endless belt supported upon two or more drums or rollers as shown in U. S. Patent No. 3,963,549.
  • the manufacturing process is initiated by detachably fastening the end of strip 92 to the periphery of the forming member F by means of clamping devices (not shown) so that movement of the periphery in the direction of arrow Q will pull the strip from the supply roll and through adhesive station B.
  • Strip 92 is attached to the forming member approximately at location T.
  • the end of strip 92 is pulled around once and then the end of strip 82 is attached at approximately the same location by means of a second clamping device (not shown).
  • Adhesive stations A and B are then placed in position for application of the adhesive to each strip.
  • roller 86 picks up adhesive from trough 88 and supplies it to the set of applicator wheels M which in turn apply the adhesive to the underside of the strip in a plurality of narrow transversely spaced bands extending longitudinally along the strip length, bands Al, A2, A3 and A4 being applied by applicator wheels Ml, M2, M3 and M4, respectively.

  • the first cut line X-X' is preferably over the location at which adhesive was first applied to the first layer of strip 82. The distance between that location and the point of attachment T is determined by the distance between the adhesive stations and the point of attachment, that being the distance the adhesive must travel before interlamination occurs.
  • the number of tube rows produced is such that a plurality of curtains of the same height and width but having differing numbers of adjacent rows can be made simultaneously as illustrated by the cut lines Y and Y' of Figure 5,

  • Longitudinal cuts are preferably made through the adhering bands of contact to maintain the integrity of tube walls on both sides of the cut line.
  • the two resulting segments form the curtain C1 of Figure 6 which has a single row of tubes and the curtain C2 of Figure 8 which has five rows of tubes, one adjoining the other in the direction of curtain thickness.
  • the segment of Figure 6 is shown fully expanded in Figure 7.
  • the segment of Figure 8 is shown fully expanded in Figure 9.
  • an applicator wheel of varying thickness about its circumference will produce a band of varying thickness with non-parallel sides.
  • the bands of contact include an adhesive coating, the coating may contain pigments causing it to either absorb or reflect heat and light.
  • the strips are preferably of a transparent or translucent material, they may include light absorbing or light reflective material.
  • the interlaminated stack of strips is rapidly produced on the forming member through the use of multiple strip sources.
  • multiple adhesive stations are shown in Figure 4, it is to be understood that a single adhesive station may apply bands to each side of a single strip with the bands on one side being spaced transversely in staggered relation to the bands on the opposite side. Where adhesive bands are applied on opposite sides of the same strip, a strip without adhesive is interleaved between each adhesive strip to produce the staggered tubular structure illustrated in the drawings.
  • a single strip can be wound with bands applied alternately to opposite sides in the staggered relationship required, each set of bands extending for one revolution of the forming member.
  • the uppermost and lowermost strips of the curtain may be of a sheet material thicker than the intervening strips forming the body of the curtain. Similarly, the outer edges of each strip may be thicker than the central portion. Such increases in thickness would provide reinforcement for those parts of the curtain subject to greatest stress and the most wear and tear.
