Definitions

  • the present invention relates to a temporary cover and, in particular but not exclusively, to a temporary insulating cover for sealing an opening such as a window of a building.
  • a temporary window or door cover may be needed. For example, on construction sites it may be desirable to temporarily seal an opening in a building to prevent or minimize ingress of water and debris that might be carried in by wind. It might also be desirable to temporarily cover an opening to maintain a temperature inside the building and prevent severe weather conditions affecting the building interior. This might also be desirable for buildings that are damaged by war/conflict, terrorism, natural disasters and other accidents. Even a single broken window can render a building uninhabitable or dangerous. It is not always feasible to insert/replace the damaged window/door with another permanent one straightaway. In conflict situations, this might in fact not be desirable as there may be an ongoing risk of further damage .
  • an insulative panel comprises multiple layers of polymeric material provided as an envelope surrounding a multi-layer insulating baffle .
  • the baffle comprises a number of inflatable channels.
  • the envelope is sealed along all edges, except where a valve is provided that permits air to be pumped in to inflate the envelope and fill the baffle channels with air.
  • a valve is provided that permits air to be pumped in to inflate the envelope and fill the baffle channels with air.
  • the resulting structure when installed in a building, provides insulation, and can permit light entry where transparent/translucent materials are used. However, the whole system is rather complex and bulky. It also requires inflation that may either take a lot of effort for a person to perform, or requires a pump or source of pressurized air, that might not be readily available depending on the situation/surroundings.
  • US 4,255,907 also discloses a transparent, inflatable storm window comprising two sheets of plastic material separated by a number of interior spacing support walls and housed around its perimeter by a frame . This window is also designed to be inflated via a valve, and the rest of the window is sealed.
  • Both windows described above are intended to be manufactured in predefined sizes. However, that particular size will not be suitable for all applications e.g. it might fit a window, but not a door. Providing a large panel might be more universally useable as it would cover smaller ones, but that would be relatively more expensive and wasteful of resources.
  • a temporary cover comprising a plurality (e.g. two) sheets of material.
  • the plurality or two sheets of material are preferably overlaid or aligned with respect to each other.
  • the cover may also have a plurality of supports or support surfaces fixed between the two sheets of material.
  • the cover may further comprise a fastener for releasably securing the sheets relative to each other in a second position.
  • the supports may be moveable between a first position in which the supports are substantially parallel to the sheets and a second position in which the supports are at an angle to the sheets.
  • the plurality of supports In use, when the plurality of supports is in the second (upright or expanded) position, it provides structural support to the sheets of material. When the plurality of supports is in the first (flat or unexpanded) position, it allows the temporary cover to be stored flat or rolled up for ease of storage and transportation when not in use .
  • the invention advantageously facilitates quick repair of an opening in a building (e .g. where a window has been broken) with an inexpensive and simple product.
  • the temporary cover comprises very few component parts, all of which are inexpensive, light and readily available . This advantageously enables easy sourcing, simple and low cost manufacture and easy distribution.
  • the sheets of material may be flexible. This allows the temporary cover to be stacked or rolled up when not in use.
  • One or more of the supports may have a higher stiffness and/or rigidity than the sheets of material.
  • the supports may be rigid or semi-rigid.
  • the supports having a higher stiffness than the sheets of material allows the plurality of supports to provide structural support to the sheets of material when the plurality of supports are in the second position i.e. the temporary cover is in use.
  • the stiffness/rigidity of the supports is not, however, so great as to prevent the cover being rolled in either the longitudinal or transverse direction.
  • Each support may be attached at respective opposing edges to and between the sheets of material. This advantageously couples the sheets together and enables the plurality of supports to easily move between the first and second positions.
  • the supports When the supports are secured in the second position, the two sheets of material are separated (by a distance corresponding to the width of the supports). Air may be present or may be trapped between the supports and between the two sheets of material when the supports are in the second position to provide insulation.
  • the open edges of the temporary cover may be sealed to improve the effectiveness of the insulation.
  • One or more of the supports may have at least one aperture, notch or cut-out.
  • the at least one aperture, notch or cut-out may be provided on one or more of the edges of the support and/or within the support.
  • each support has at least one notch section on each longitudinal edge (that is attached to one of the sheets).
  • the notch(es) provide(s) a gap or discontinuity in the attachment of the supports to the sheets of material to permit airflow therethrough.
  • the sheets are preferably formed of a material that can be cut with a simple cutting instrument such as a knife or scissors.
  • the notches (which are preferably all aligned on the transverse axis relative to each other) can provide a cutting guide to help a user cut the cover in a straight line . This further helps the user to cut the temporary cover to the correct size consistently across the width of the temporary cover.
  • the presence of at least one notch also enables a user to more easily seal the temporary cover around the edges by allowing the edge portions of the sheets of material to be brought closer together (due to the reduced width of the support in the vicinity of the notch).
  • the fastener In the flat position, there is no sealing around any of the sheet edges. In the expanded position, the fastener seals the cover along one edge. Air can flow within, into and out of the cover via any unsealed edges.
  • the fastener may be or comprise a temporary, sealable and releasable fastener.
  • the fastener may be one or more of a press-fit fastener, a hook and eye fastener, a zip fastener, an adhesive fastener, or a clip fastener, e.g. Ziploc® fastener.
  • the fastener acts to secure the sheets relative to each other when the supports are in the second (upright) position.
  • the sheets of material and plurality of supports may be made from a material that is easily cut using a sharp implement. This allows the user to quickly and simply cut the temporary cover to the correct size for the application at hand. For example, a plastics material such as polyethylene.
  • the supports are elongate supports that substantially span the length of the temporary cover. However, it is appreciated that the supports may alternatively substantially span the width of the temporary cover. When the plurality of supports are in the first position the supports and the sheets are all substantially parallel permitting the temporary cover to be rolled up (in either the longitudinal or transverse direction).
  • the supports are elongate strips with notches provided in opposing edges thereof, but it will be appreciated that other arrangements may be used.
  • the supports are elongate strips with a generally I-shaped cross-section.
  • the supports are elongate strips with a generally C-shaped cross-section. This allows for the temporary cover to spring open when being unrolled for use.
  • the supports may be attached to the sheets by any convenient means, e.g. by adhesive, welding etc.
  • the cover comprises three sheets of material.
  • a third sheet may be attached to (and between) the first and second sheets.
  • Adhesive e.g. in the form of strips is convenient, but welding and/or other fastening means may be used.
  • the third sheet may be attached to one of the other sheets at preferably regular spacings along the length of the sheets. Cuts may be formed in the third sheet, adjacent or near one side of the adhesive/fastening. The cuts may be formed e.g. by laser cutting or with a cutting implement such as a blade . Further adhesive strips/fastenings may be formed on the third sheet adjacent/in the vicinity of and substantially parallel to the cuts. The adhesive/fastenings on either surface of the third sheet may be located either side of the adhesive strips/fastenings.
  • the cuts and the adhesion/attachment permits the first and second sheets to be moved with respect to one another so they can be separated at an angle e.g. up to a direction that is substantially perpendicular to the plane of the sheets.
  • the separated parts of the third sheet form the supports.
  • the supports can move from a first position substantially parallel (flat) to the plane of the sheets to a second position that is at an angle e.g. substantially perpendicular to the plane of the sheets.
  • the middle sheet may comprise one or more weakened portions e.g. lines of weakness that assist the sheet in bending in the desired manner from the first or "flat" position to the second or “angled” or "perpendicular" position.
  • the supports may be manufactured from the sheet material itself via a process involving folding, layering, and adhering or welding of the sheet material.
  • a single support alone may be used, e.g. for covering a small opening.
  • the single support may have a plurality of surfaces, creases, folds etc. extending across the cover.
  • the temporary cover may further comprise a second fastener for securing the temporary cover in or to a building or other structure.
  • the second fastener may be double sided adhesive tape .
  • the sheets of material may be transparent, semi-transparent or translucent.
  • the advantage of this feature is that light is able to be transmitted through the temporary cover.
  • the temporary cover of the first aspect of the invention may be supplied as part of a repair kit as defined in claim 19.
  • a method of assembling and using the kit of the third aspect of the invention as defined in claim 21 is provided.

  • FIG. 2A shows an alternative embodiment of a temporary cover
  • FIG. 3 shows an alternative embodiment of a temporary cover
  • FIG. 4 shows a temporary cover in a rolled configuration
  • FIG. 5 depicts a series of method steps for assembling and using the temporary cover
  • FIG. 6 shows an alternative embodiment of a plurality of supports.
  • FIGs 1 and 2 show a temporary cover or temporary window 10.
  • the temporary cover 10 comprises two sheets of material 12a, 12b, with a plurality of supports 14 located between the sheets of material 12a, 12b. Although two supports 14 are shown in Figures 1 and 2, it will be appreciated that any number of supports 14 may be provided. It would also be possible for the temporary cover 10 to comprise just a single support 14.
  • the sheets of material 12a, 12b are generally and conveniently rectangular, but other shapes may also be used.
  • the sheets 12a, 12b are of substantially the same size (length and width) .
  • the sheets of material 12a, 12b are positioned relative to one another such that they substantially overlap with their transverse edges 13a substantially in line with one another. Their longitudinal edges 13b are offset in the arrangement of Figure 1.
  • the plurality of supports 14 is able to move between the flat position of Figure 1 and an expanded or upright position, as shown in Figure 2. In the flat position, the sheets 12a, 12b and the supports 14 all lie in the same plane . In the expanded position, the supports 14 sit at an angle e.g.
  • the supports 14 will be at an angle of between substantially 0° and 90° with respect to the plane of the sheets 12a, 12b.
  • a temporary securing means 22 is provided which can, in use, secure the sheets of material 12a, 12b in the expanded position where the sheets of material 12a, 12b are separated from each other. In this position, the sheets 12a, 12b are secured relative to each other with the plurality of supports 14 in the angled/upright/perpendicular position.
  • the sheets of material 12a, 12b are preferably transparent, semi-transparent or translucent to allow light to be transmitted through the temporary cover 10.
  • the sheets of material 12a, 12b may also be easily cut by a sharp implement so that the temporary cover 10 can be cut to the desired size.
  • a suitable material for the sheets of material 12a, 12b is polyethylene, but it will be appreciated that other flexible and transparent or translucent materials may be used.
  • One or more of the supports 14 have a higher rigidity or stiffness than the sheets of material 12a, 12b in order to provide support to the sheets of material 12a, 12b when in the upright position. This ensures that, in the expanded position, the sheets 12a, 12b are retained at a predefined separation (equal to the height of the supports 14).
  • the supports 14 are, however, semi-flexible to permit flexing or bending.
  • the plurality of supports 14 are continuous elongate supports that extend fully along the length of the temporary cover 10.
  • the supports 14 are arranged substantially parallel to each other and to a longitudinal edge 13b of each of the sheets of material 12a, 12b.
  • the supports 14 are attached at respective opposing longitudinal edges 18, 20 to the sheets of material 12a, 12b. This allows the plurality of supports 14 to be easily moved in unison between the flat position and the upright position.
  • the supports 14 are formed from a third sheet 12c interposed between the first and second sheets 12a, 12b.
  • the third sheet 12c may be attached to the first sheet 12a e.g. with adhesive 19 and, for example, in strips. Adhesive strips 19a spanning the width of the sheet 12a may be applied.
  • the third sheet 12c may be cut in situ to form cuts 17 in the third sheet 12c.
  • the cuts may be formed e.g. by laser cutting or with a cutting implement such as a blade .
  • the cuts may be formed adjacent/in the vicinity of and substantially parallel to the adhesive strips 19a. Further adhesive strips 19b may be formed on the third sheet 12c.
  • the adhesive strips 19b may be applied adjacent/in the vicinity of and substantially parallel to the cuts 17 such that the adhesive strips 19a, 19b are located either side of the cuts 17.
  • the second sheet 12b 12a may then be applied to the adhesive 19b to form a stack.
  • a magnified view is shown to illustrate this.
  • the cuts 17, and the adhesion between the first sheet 12a and the third sheet 12c, and between the third sheet 12c and the second sheet 12b, and the cuts permits the first and second sheets 12a, 12b to be moved with respect to one another so they can be separated at an angle/in a direction substantially perpendicular to the plane of the sheets 12a, 12b.
  • the cuts 17 in the third sheet 12c form the supports 14.
  • FIG. 2A(d) The fully separated position is shown in Figure 2A(d) .
  • the supports 14, as formed from the third sheet 12c are shown substantially perpendicular to the plane of the sheets 12a, 12b.
  • the third sheet 12c could be adhered to the second sheet 12b initially, and then to the first sheet 12a.
  • the sheets 12a, 12b, 12c could be attached together with other means e .g. welding or with other fastening means.
  • the "middle" sheet 12c is thicker and/or more rigid than the "outer" sheets 12a, 12b.
  • the outer sheets 12a, 12b may, for example have a thickness of about 125 microns (micrometres).
  • the middle sheet 12c may have a thickness of about 160- 250 microns.
  • the ratio of thickness of the middle to outer layers may be approximately 1.5-2.5 (or higher), depending on the exact material specifications.
  • the supports 14 are at least twice as strong compared to the outer sheets 12am 12b to aid folding/unfolding .
  • This can be achieved through using cross-laminated sheets, thicker sheets or both for the third sheet 12c/supports 14.
  • Other factors such as overall rigidity, UV-stability, weight etc. have an effect as well, but having a thicker and/or stronger or more rigid third layer 12a/supports 14 (in comparison to the outer layers 12a, 12b) can assist folding/unfolding.
  • Cross-laminating sheets refers to a process similar to manufacturing plywood, where multiple layers are fixed e.g. adhered on top of each other at an angle of about 90° in order to produce a more consistent and rigid material.
  • the mechanical characteristics of these sheets roughly correspond to those of a single sheet that is twice as thick (and therefore twice as heavy). This allows less material to be used while still providing a similar rigidity but without the expense of such materials. It has been found that a 200micron cross laminated sheet appears to work well (which behaves similarly to using 0.5mm non-cross-laminated supports 14.
  • the outer layers 12a, 12b may be non-cross-laminated, or may be cross-laminated.
  • the rigidity of each layer may be chosen dependent on the desired application.
  • the middle sheet 12c is weakened to aid in the sheet 12c being able to fold precisely and where needed.
  • Lines or areas of weakness 21 may be provided substantially parallel to the adhesive strip(s) 19a, 19b and/or the cut(s) 17.
  • Heat treatment may be used, applied along a line where the sheet is to be folded, to weaken the material where it needs to fold. This is shown as lines 21 in Figure 2A(d); omitted from the other figures of Figure 2A for clarity.
  • the heat may be applied e.g. by using a soldering iron, a heated roll or as part of the blade or cutting tool that cuts the middle sheet 12c once glued to the first one 12a.
  • the middle sheet 12c may be scored or perforated or otherwise weakened (without breaking).
  • Each support 14 may therefore be formed with a substantially straight edge along its width, an adhesive strip 19b substantially parallel to the edge, a weakened line 21 or area substantially parallel to the edge, a middle portion that can move from a position substantially parallel to the first/second sheet 12a/ 12b to a position at an angle/substantially perpendicular to the first/second sheet 12a/ 12b, another weakened line 21 or area substantially parallel to the edge, an adhesive strip 19a substantially parallel to the edge, terminating in the other substantially parallel edge .
  • the plurality of supports may be elongate strips with a generally C-shaped cross-section. This allows for the temporary cover to spring open when being unrolled for use.
  • the supports may be manufactured from the sheet material itself via a process involving folding, layering and welding of the sheet material.
  • One or more notches 16 may be provided in the opposing edges 18, 20 of each of the plurality of supports 14.
  • the notches 16 are periodically spaced along the length of each of the plurality of supports 14.
  • the notches 16 are present in only one edge 18, 20 of each of the plurality of supports 14, or no notches 16 are present in either of the edges 18, 20 of each of the plurality of supports 14.
  • the no notches are provided in the supports 14, but the sheets of material 12a, 12b are instead configured to periodically provide a gap in the join between the sheet 12a, 12b and the support 14.
  • the notches 16 may be substantially semi-circular or triangular cut-outs, but it will be appreciated that other configurations are possible. Further cut-outs could be provided in the body of the support, to reduce/minimise the weight of the product and help keep resource usage and shipping/transportation costs down (but whilst still maintaining the necessary degree of rigidity).
  • the notches 16 provide a gap or discontinuity in the seal between the supports 14 and the sheets of material 12a, 12b. This permits air flow between the sections of channels of the temporary cover 10 that are defined/separated by the plurality of supports 14. This advantageously permits air to freely flow into and between the different channels. As such, no external active air/fluid supply is needed - the temporary window 10 automatically fills with air.
  • the temporary cover 10 is made of a flexible, often sheet plastics material, it can easily be cut to a desired size by a sharp implement e.g. a knife or scissors.
  • a sharp implement e.g. a knife or scissors.
  • the notches 16 provide an indication or a guide to a user showing where to cut the temporary cover 10.
  • cutting along a line of notches 16 allows the user to more easily cut the temporary cover 10 to the desired length (as there is a lower amount of more rigid material to cut through).
  • Cutting along the aligned notches 16 also permits cutting uniformly i.e. in a substantially straight line across the width of the temporary cover 10.
  • the notches 16 on each side define a region of the support 14 that has a smaller width than the rest of the support. In an embodiment, the thinner portion of the support is approximately half the total width of the support, but it will be appreciated that other ratios can be used.
  • the sheets of material 12a, 12b have a thickness of about 200 microns. In other embodiments, the sheets of material 12a, 12b have a thickness of between about 100 microns and about 500 microns.
  • the supports 14 have a thickness of between about two times and about four times the thickness of the sheets of material 12a, 12b.
  • the notches 16 also provide an edge taper on the plurality of supports 14, facilitating the sheets of material 12a, 12b to be brought closer together in order that the temporary cover 10 can be sealed more easily.
  • the open edges of the temporary cover 10 can conveniently be sealed using an adhesive tape 28.
  • other sealing means e.g. staples, adhesive pins etc. may also be used.
  • the temporary securing means 22 secures the sheets of material 12a, 12b to each other when the plurality of supports 14 is in the upright position. The temporary securing means 22 prevents the plurality of supports 14 from returning to the flat position when the temporary cover 10 is in use, and maintains a separation distance between the two sheets 12a, 12b.
  • the temporary securing means 22 extends continuously (along the entire width) along one edge 13b of the temporary cover 10, parallel to the plurality of supports 14. In an alternative embodiment, shown in Figure 3, the temporary securing means 22 extends continuously along two opposing edges 13b of the temporary cover 10, parallel to the plurality of supports 14. In embodiments of these (not shown), the temporary securing means 22 extends along one or more parts of the edge 13b of the temporary cover 10, parallel to the plurality of supports 14. In an embodiment (not shown), sections of temporary securing means 22 are provided, with gaps in between that are aligned with the notches 16. This further facilitates cutting the temporary cover 10 to the desired size.
  • the external faces of sheets of material 12a, 12b may be provided with adhesive along the edges 13b where the temporary securing means 22 is present.
  • the adhesive indicates to the user where best to start the installation of the temporary cover 10.
  • Another advantage is that the adhesive improves ease of installation of the temporary cover 10 for the user. The user does not have to provide separate means for adhering the temporary cover to the edges of the opening being covered.
  • a further advantage is that by positioning the adhesive on the same side of the temporary cover 10 as the temporary securing means 22, the application of force to fasten the temporary securing means 22 is along the edge 13b where the adhesive is applied. This arrangement reduces or removes any rotational forces (induced during fastening of the temporary securing means) which may act to break the bond between the adhesive and the edges of the opening being covered, causing the temporary cover to become detached from the desired location.
  • the temporary securing means 22 is a Ziploc® fastener (with or without a slider).
  • This fastener 22 has a male connector part that is fixed to one of the sheets 12a, 12b and a female connector for receiving the male connector that is fixed to the other sheet 12b, 12a.
  • Such fasteners are readily available and inexpensive. It will, however, be appreciated that other types of fastener may also be used. For example, a hook and loop fastener (Velcro®), hook-hook fasteners, zips, resealable adhesive strips or pads, double sided adhesive tape, or any suitable reuseable sealing means.
  • the supports 14 are flexible enough when in the flat position that the temporary cover 10 can be rolled up for ease of storage and/or transportation.
  • Figure 4 shows the temporary cover 10 in a rolled up configuration suitable for storage and transportation.
  • the temporary cover 10 is shown rolled around a cylindrical central support 26 with the supports 14 having their length rolled about the axis of rotation. This is possible due to the flexible nature of the plurality of supports 14.
  • the temporary cover 10 can also be rolled with the length of the plurality of supports 14 parallel to the axis of rotation.
  • a strip of adhesive tape 30, e.g. double sided adhesive tape 30, may be provided on or with the cover 10.
  • a length of double sided tape 30 is affixed to an edge 13b of one of the sheets 12a, 12b. The remaining protective cover may be removed when needed to fix the cover 10 in place across an opening.
  • Figure 4 also shows the temporary cover 10 as part of a kit 24 that can be supplied to the user, comprising a temporary cover 10 rolled around a cylindrical central support 26.
