Definitions

  • This invention relates to collapsible and expandable curtains of the kind having in their expanded state a pre-determined width and a pre-determined height and comprising a plurality of expandable tubes, the longitudinal axis of each of which extends in the direction of curtain width.
  • Such curtains can be used as thermally insulating curtains over openings such as doors, windows and the like.
  • the invention also relates to a method of producing such curtains from 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 cellulated structure can be pressed together for transporting and expanded for installation, the insulating 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.
  • U.S. Patent No. 2734843 is disclosed a method for producing unexpanded blocks of expandable honeycomb.
  • the method described includes the steps of applying longitudinally extending spaced parallel lines of adhesive to face surfaces of web material, cutting the web material into completely separated flat sheets of uniform size and thereafter adhering said sheets to one another with the obverse side of each sheet adhered to an adjacent sheet by a plurality of spaced parallel lines of adhesive and with the reverse side adhered to an adjacent sheet by lines of adhesive disposed in staggered parallel relationship to the said lines of adhesive by which its obverse side is adhered. Since the web material is cut into separated flat sheets which are thereafter stacked and then adhered to one another along said parallel lines, the method is quite slow.
  • a method of manufacturing a selectively collapsible and expandable curtain having in its expanded state a predetermined width and a predetermined height and comprising a plurality of expandable tube the longitudinal axis of each of which extends in the direction of curtain width, said method comprising the steps of:-
  • each tube when fully expanded having a substantially rectangular cross-section with top and bottom walls whose widths are defined by an opposing pair of said bands on upper and lower adjacent layers and sidewalls whose heights are defined by upper and lower side sections comprised of the portions of said thin film material lying between said pair of opposing bands and a pair of transversely spaced bands joining said upper and lower adjacent layers on either side of said opposing bands;
  • the method of the invention is much simpler and faster and more economical than heretofore known.
  • two or more lengths of the thin film material from different sources may be wound on said forming member simultaneously in an interleaved manner, the material from each source being passed through a station at which adhesive is applied before being wound on said forming member.
  • the number of said bands may be such that a plurality of sets of said superimposed tubes are formed adjacent one another transversely across said forming member.
  • the method of the invention may include the step of cutting at least one intermediate set of said superimposed tubes longitudinally along said opposing bands to form at least two separate curtains each having said predetermined width and said pre- determined height in its expanded state.
  • the minimum aggregate number of said first and second bands across the width of the thin film material is 3, additional bands being provided depending upon the number of adjoining tube columns desired.
  • the number of layers wound upon the forming member is chosen to yield the desired number of tubes in each column, which in turn determines curtain height.
  • a column refers to tubular units aligned with curtain height and not to successive units in the direction of curtain thickness.
  • the curtain is extended to its full height when the tubes are fully expanded.
  • the tubes can be collapsed 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 super- imposed layers of film material.
  • the top may be secured to amounting slat and the bottom to a second slat movable relative to the top slat. 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.
  • Curtains of varying height can be made depending upon the number of layers of thin film material superimposed upon the forming member. Multiple curtains of less height than originally formed can also be made by cutting the linear column or columns 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.
  • a curtain produced according to the invention 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 of course be oriented in a horizontal plane rather than the normal vertical plane and pulled taut to serve as insulation beneath a floor or above a ceiling.
  • the tubular curtain which can .be produced by the method of the present invention, is generally designated 10 in Figure 1 of the drawings.
  • the curtain is comprised of a column of tubes C1 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 comprises an upper strip 14 and a lower strip 15, each strip having two longitudinally extending edges. The edges of one strip abut the corresponding edges of the other strip along bands of contact 16 and 17 on opposite sides of the tubular cavity.
  • the portions of each strip within the bands of contact 16 and 17 are adheringly secured together by appropriate means compatible with the strip material, preferably an adhesive.
  • upper strip 14 has two side sections 14a and 14c and a mid section 14b
  • lower strip 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 C1 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.
  • different relative dimensions of the corresponding parts are shown in Figure 7.
  • the side sections are approximately equal to the mid sections.
  • the column C1 as formed has loose side sections 21 a and 21 c and the loose 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 strips contain essentially still or dead air since any transverse movement of air is prevented. 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 plastics sheeting will satisfy these requirements.
  • Each sidewall of the tubular cavity is a composite of two side sections, one from the upper and the other from the lower strip.
  • the 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.
  • curtain C2 is comprised of a plurality of tube columns 31, 32, 33, 34 and 35, one adjoining the other in the direction of curtain thickness.
  • Each column is comprised of a plurality of superimposed tubes having the same structure as the tubes in row C1 of Figure 1.
  • 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 super- imposed tubes of column 31 are joined together by bands of contact A1, the tubes of column 32 by bands B2, the tubes of column 33 by bands A2, the tubes of column 34 by bands B3, and the tubes of column 35 by bands A3.
  • bands form the mid sections of the corresponding strips.
  • the upper and lower side sections of tubes 31 are joined together on opposite sides of each tubular cavity by bands of contact B1 and B2, the side sections of tubes 32 by bands A1 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.
  • bands intervening between the outer vertical walls 40 and 41 of curtain C2 serve both as a band of contact for the superimposed tubes and as a band of contact joining the side sections of the tubes in an adjacent column.
  • Bands inside of outer columns 31 and 35 join the side sections of two adjacent columns, 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.
  • Figure 3 there is shown a pair of pull cords 50 and 60 and corresponding pulley mechanisms 51 and 61 for manipulating the multi-column 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 column 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 fasteners (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 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 side 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 columns 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 columns making up the curtain.
  • the number of columns 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.
  • the side sections shown in Figure 9 have a width about equal to that of the mid bands. If the outermost bands B1 and B4 are to be included between the slats, the slat width should be increased by those increments.
  • a first supply roll 80 and a second supply roll 90 provide continuous lengths 82 and 92 of thin-film material, preferably thin sheets of plastics.
  • Length 82 passes through an upper adhesive station A comprised of a guide roller 83 for tensioning and directing the length over a series of applicator wheels M 1, M2, M3 and M4 mounted for rotation upon a shaft 85.
  • the applicator wheels M contact the underside of length 82 and underlying those wheels is a pickup roller 86 mounted for rotation partially submerged in an adhesive contained in a trough 88.
  • Length 92 passes through a lower adhesive station B comprised of a guide roller 93 for tensioning and directing the length 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 length 92 and underlying those wheels is a pickup roller 96 mounted for rotation partially submerged in an adhesive contained in a trough 98.
  • length 92 is interleaved beneath length 82 and the two lengths 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 lengths 82 and 92 thereon in interleaved fashion.
  • Guide rollers 83 and 93 maintain sufficient tension on the lengths to produce a flat even stack of superimposed layers 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 length 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 length from the supply roll and through adhesive station B.
  • Length 92 is attached to the forming member approximately at location T.
  • the end of length 92 is pulled around once and then the end of length 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 length.
  • 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 length in a plurality of narrow transversely spaced bands extending longitudinally along the strip length, bands A1, A2, A3 and A4 being applied by applicator wheels M1, M2, M3 and M4, respectively.
  • roller 96 picks up adhesive from trough 98 and supplies it to the set of applicator wheels N which in turn apply the adhesive to the underside of the length in a plurality of narrow transversely spaced bands extending longitudinally along the length, bands B1, B2, B3, B4 and B5 being applied by applicator wheels N1, N2, N3, N4 and N5, respectively.
  • the lengths are wound in interleaved fashion around the periphery of the forming member to produce bands of contact adheringly securing each layer of material to the next superimposed layer.
  • the upper set of adhesive bands A is offset transversely relative to the lower set of adhesive bands B as viewed from left to right in Figures 4 and 5. This offset between adhesive bands A relative to adhesive bands B staggers the bands of adhering contact between successive layers.
  • the transverse distance between adjacent bands on opposite sides of the same layer substantially defines the width of the unadhered side section of each tube wall. It is this staggered relationship that produces the expanded curtain structures shown in Figures 6 through 9.
  • the distance around the periphery of the forming member is at least equal to the width of the curtains to be made.
  • the winding operation is stopped and the wound stack of tubes cut transversely along a line X-X' shown in Figure 4.
  • a single cut produces a curtain width equal to the circumferential distance. Multiple cuts corresponding to the number of curtain width multiples making up the circumferential distance will produce the corresponding number of curtains.
  • the first cut line X-X' is preferably over the location at which adhesive was first applied to the first layer 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 columns produced is such that a plurality of curtains of the same height and width but having differing numbers of adjacent columns can be made simultaneously as illustrated by the cut lines Y and Y' of Figure 5.
  • Two cut lines are employed to minimize the width of resulting side bands B4 and B4'.
  • 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 column of tubes and the curtain C2 of Figure 8 which has five columns of tubes, one adjoining the other in the direction of curtain thickness.
  • the interlaminated layers are rapidly produced on the forming member through the use of lengths of material from multiple 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 length 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 length, a length without adhesive is interleaved with it to produce the staggered tubular structure illustrated in the drawings.
  • a single length can be wound with adhesive 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.
