Definitions

  • This disclosure relates generally to storm windows, and more particularly to a press fit storm window that may include a facility for controlling blowout events.
  • Storm windows are generally mounted on the outside or inside of main windows of a home or business. They are oftentimes used in cold climates to reduce energy leakage from the windows, for instance, cold air leaking into a house through the main windows. Storm windows may be mounted externally or internally, and are generally made from glass, plastic, or other transparent material. In some instances storm windows may be translucent or opaque.
  • a method of measuring efficiency of thermal insulation which is the opposite of a rate of heat transfer, is R-Value.
  • An R-value number indicates the relative resistance to heat flow, where a higher R-value has greater thermal efficiency.
  • the R-value generally depends on the type and size of the insulation system being rated, for example the material selected, its size, thickness, and density.
  • R-values of multi-layer systems equal the total of the individual layered systems.
  • present-day storm window systems are difficult to install and remove.
  • present-day storm window systems are mechanically attached with mounting hardware to either the inside or outside of the main window.
  • the windows may be heavy and difficult to manipulate.
  • Other, less expensive systems use see-through plastic sheets that are taped or attached to window casings.
  • the plastic sheets may be "shrunk" using a heat gun which, when directed at the plastic sheet, causes the sheet to contract, making the sheet taught, and easier to see through.
  • Such prior art systems are, similar to the mechanical systems as described above, difficult and time-consuming to install.
  • Embodiments of the invention address these and other problems in the prior art.
  • Document US 2014/157696 discloses an airflow reduction system including an insulating panel assembly for sealing a window within a jamb, wherein the insulating panel assembly has a frame configured to fit within the jamb and a glazing panel in the frame coated with a low-emissivity or solar control coating or film.
  • Document US 5 887 392 discloses a jambliner having a multi-part design including a sash-engaging member defining a track and a pair of retaining arms extending from the sash-engaging member defining a channel.
  • Document DE 203 12 327 discloses a sealing profile for a refrigerator sliding cover.
  • Embodiments of the invention are directed to storm windows that may be easily and readily installed in a window frame of an existing window.
  • a transparent portion of the window is generally see-through and may be made from glass, plastic, such as PLEXIGLASS, or other clear, generally rigid material.
  • the window may be translucent, patterned, or opaque.
  • a resilient material forming a resilient support surrounds the edges of the transparent portion, at least in part, such that, when the resilient material is compressed smaller than its natural state, it provides a "righting" or reformation force between the window frame and the transparent portion of the storm window. This reformation force of the resilient material puts pressure both on the window frame and the edge of the storm window and frictionally holds the storm window in place without the need for mounting hardware.
  • the storm window may also include features for keeping it in place should outside forces act on the storm window system, such as a strong wind leaking through the main window, as described below.
  • Fig. 1 is a side cutaway view of a portion of a storm window.
  • a panel 130 is a rigid, transparent panel which serves as the "window" portion of the storm window.
  • the panel 130 may be made from glass, plastic, such as PLEXIGLASS, or other suitable material.
  • the thickness of the panel 130 is generally thin, such as 3.175 mm (1/8"), but other thickness panels may be used as well.
  • the panel 130 may include decorative features, such as patterned translucent portions seen in privacy rooms, such as bathrooms. Other decorative features may include stained glass or material that appears to be stained glass. Still other decorative features may include decorative grill work such as iron grill work or material that appears to be such decorative grill work.
  • the panel could be made of metal or wood.
  • a resilient support 110 generally includes a bulb portion 103 and a groove portion 107, and is positioned to generally surround at least a portion of the edge of the panel 130.
  • the resilient support 110 is mechanically held fast to the panel 130 by the "groove" 107 made from space between retaining portions 106, 108.
  • the retaining portions 106, 108 are generally spaced so that they each contact a front or rear surface of the panel 130, thereby keeping the resilient support 110 in place and from moving relative to the panel.
  • an adhesive may facilitate anchoring the resilient support 110 to the panel 130, at least in some portions of their contact.
  • the retaining portions 106, 108 are generally sized to provide enough frictional force to securely hold the panel 130 surfaces.
  • the retaining portions 106, 108 are 3.175 mm (1/8") tall, but could vary between approximately 0.79 mm (1/32") and approximately 50.8 mm (2 inches), depending on the size and material selection of the panel 130.
  • the width of the groove 107 is generally sized to exactly match the thickness of the panel 130, but may be slightly smaller or larger depending on the installation.
  • adhesives could be used to adhere or attach the panel to the resilient support 110, with or without requiring the retaining portions 106, 108.
  • the bulb portion of the resilient support 110 may take one of several cross-sectional shapes.
  • the cross section of the bulb portion 103 of the material making the resilient support 110 is circular, being formed from an outer surface 102 of the support 110 and a center "hole," the surface of which is indicated at 104.
  • the cross section of the bulb portion 103 may take many shapes, as described below, and the "hole” may be partially or fully filled with additional resilient material, or another material, also as described in detail below.
  • the resilient support 110 is formed of a yieldable material that deflects or deforms under pressure and, based on its shape and material selection, provides a return reformation force, i.e., the force that the material exerts on the contact point or points of the object causing its deformation.
  • a return reformation force i.e., the force that the material exerts on the contact point or points of the object causing its deformation.
  • the reformation force increases relative to the amount of deformation.
  • the material of the resilient support 110 produces less and less reformation force until the material returns to its "natural,” undeformed state, at which point the reformation force is zero.
  • the resilient support 110 is a single, uniform material, such as foam.
  • the resilient support 110 is made from a combination of materials, such as a silicone cover or shell filled with a foam insert.
  • the foam insert may be solid or may further include a cross sectional hole similar to the hole illustrated in Fig. 1 .
  • Other materials may also be introduced into the hole, whether or not covered by a silicone shell, such as metal, foam or plastic, shaped in various shapes, all of which together provide the resilient support 110 with the desired reformation force.
  • Embodiments of the invention may be produced from a large variety in materials, in various shapes and sizes.
  • the resilient support 110 as described above, may be made from foam, silicone, EPDM, or PVC, or derivatives, or any other material having the properties desired.
  • the cross-sectional shape of the resilient material forming the resilient support 110 can be selected for the desired properties of the storm window.
  • the bulb of the resilient support 110 may be circular, oval, spiral, elliptical, square, triangular, or may have an "open" shape, such as L, U, V, or C. In either case, if there is a hole, such as the one illustrated at 104 of Fig.
  • another material or set of materials may fully or partially fill the hole to provide desired qualities of reformative force, resiliency, compression set (or compression memory), etc.
  • the materials used in the herein-described storm windows are subjected to large temperature variations and therefore should be selected to withstand the expected conditions, or to have their use limited only to conditions where the material properties will be satisfactory.
  • the storm windows will generally be exposed to the sun, they should be resistant to radiation, such as UV radiation.
  • Fig. 2 is a front view of a storm window 200.
  • the storm window 200 includes a panel 230 surrounded by sections 210, 212, 214, and 220 of the resilient support 110 described above with reference to Fig. 1 .
  • Individual sections of the resilient material may join with mitered corner joints, such as illustrated at 216, 218, or they may join with butt joints, as illustrated at 222, 224. Corner joints 216, 218 and butt joints 222, 224 may be sealed with thermal sealer or adhesive, or may be joined in other conventional methods.
  • the bottom section 220 may be formed of a different material than the other sections 210, 212, 214 based on operational properties desired of the window 200, or based on other reasons.
  • the bottom section 220 is formed of a rigid or semi-rigid material, such as aluminum, to stiffen the panel 230 and to prevent "droop".
  • any of the sections 210, 212, 214, 220 may be formed of a different material, or have a different shape, or other properties, than the others.
  • a rectangular window is illustrated in Fig. 2 , as it is the most common window shape, embodiments can have storm windows of any shape.
  • Fig. 3 is a diagram illustrating installation of the storm window 200 of Fig. 2 inserted into a main window 00.
  • the storm window 200 is gently or forcefully inserted into a frame 380 of the main window 300.
  • the size of the storm window 200 is selected such that the overall dimensions of the panel 230 plus the sections 210, 212, 214, and 220, when such sections are in their natural, non-deformed state, is larger than the frame 380 of the main window.
  • the sections 210, 212, 214, and 220 deflect or deform from their natural state, as described above.
  • the resilient support 110 Fig.
  • the resilient material 110 makes up the sections 210, 212, 214, and 220 remains in a continuously deformed state, by virtue of the selection of size of the storm window. Because the resilient material 110 is deformed, it produces the reformation force described above, between the edges of the panel 230 and the frame 380 of the main window 300. This reformation force, in conjunction with the frictional forces where the resilient support 110 meets the frame 380, keeps the storm window 200 in place. As described above, the resilient support 110 keeps the panel 230 in place by virtue of the groove 107 ( Fig. 1 ).
  • Figs. 4 and 5 show additional detail of a corner section of a storm window 400, both before ( Fig. 4 ) and during ( Fig. 5 ) installation into a frame 580.
  • Fig. 6A is a perspective view of a corner portion of a storm window.
  • a silicone cover 603, 607 may also include nipple sections 601, 609, which may be inserted in a mating receiving portion of a section of resilient material of a resilient support, such as sections 210, 212, 214, or 220 described above.
  • the nipple portion 601, 609 is shaped such that, when inserted into the resilient support, that the outside surfaces of the receiving portion matches to the outside surface of the silicon cover 603, 607, to make a uniform appearance.
  • FIG. 6A are simply sections of the support having a diameter that matches the inside diameters of the silicone cover 605, 607, as well as the inside diameter of a section of the resilient support, thereby providing a joining surface that may be friction fit or otherwise fixed.
  • a groove 617 is formed between retaining portions 605, 615, which is shaped to accept a panel (not illustrated in Fig. 6A ).
  • the cover pieces 603 and 607 join at a corner 619.
  • a corner piece 637 may be formed of multiple pieces, such as in Fig. 6A , or may be made in a single-constructed piece.
  • the corner piece 637 may include a "fin" 641, formed of a relatively thin piece of material, which may be the same or different material used to make the corner piece 637.
  • the fin 641 is generally yieldable and more easily deformed than the corner piece 637 itself.
  • the fin 641 may further include a notch 643, which allows the fin 641 to better deform in a corner of a window frame (not illustrated). In other words, without the notch 643, the fin 641 may "pucker," due to excess material, if placed into a tight corner. In embodiments that include the notch 643, less or no puckering occurs.
  • a curved corner is illustrated (excluding the fin 641) rather than a corner having straight lines.
  • This feature of the design was included because, in many installations, the resilient material tends to bunch up and "buckle" in corners, due to so much material being present.
  • Embodiments of the invention have sought to minimize the amount of material in the corners in a number of ways, such as the rounded corners as illustrated.
  • the corner pieces do not form a 45 degree angle when not installed, and instead are separated by a pie-shaped gap between areas where the horizontal resilient material meets the vertical resilient material before being installed. When installed, the resilient material compresses to fill the corner with a minimum amount, or even no amount of gaps between the resilient material and the window frame.
  • dimension "a” may extend from approximately 6.35mm (1/4 inch) to 76.2mm (3 inch)
  • dimensions "b” and “c” may be 1.59mm (1/16")- 102mm (4") depending on the installation
  • dimension "d” may be 8.47mm (1/3")- 114mm (4.5")
  • dimension "e” may be 3.175mm (1/8")- 50.8mm (2") again, depending on the size and material selection making the corner piece 637.
  • These dimensions may vary from 10-500% depending on the particular details.
  • the storm window is sized according to the dimensions of the window frame in which the storm window is being installed.
  • the storm window is inserted into the window frame in which a deformable, resilient material of the support is compressed during the insertion.
  • the resilient material of the support exerts a reformation force between the window frame and the resilient support of the storm window. This reformation force coupled with frictional forces between the resilient support and the window frame, and to an extent, to the friction forces holding the panel in place by the resilient support, holds the storm window securely in place.
  • the storm window When the wind forces are light, the storm window may simply re-position itself within the window frame. When wind forces are strong, however, the storm window may be blown completely out of the window frame, which could fall into the house and cause damage or injury. In any event, if the storm window is unseated by wind or other forces, it is generally no longer seated correctly in the window, such that wind may enter the house, which may significantly reduce the insulation value of the storm window.
  • Fig. 7A is a top cross-sectional view of a storm window 700 described above.
  • a panel 706 is held in place by side resilient support sections 702, 704.
  • a resilient support section that would otherwise cover the top edge of the panel 706 is omitted.
  • description of the storm window 700 is omitted for brevity, and can be found above.
  • Fig. 7B is a top cross-sectional view of a storm window 710 that in many respects is identical to the storm window 700 of Fig. 7A .
  • a panel 716 in the storm window 710 is formed with a pre-determined curve along its entire the top edge.
  • the bottom edge (not illustrated) may be similarly curved, which gives the panel 716, overall, a partial-cylinder shape, and thereby creating a relatively stiff construction of the panel.
  • Such a panel 716 is very resistant to bending, under force, across its vertical axis, while it would be more inclined to deflect across its horizontal axis.
  • Using the bended shape of the panel 716 in a storm window such as described above generally creates a more rigid, stronger constructed window that may be able to withstand more force with less material than a conventional storm window having a flat panel, such as the panel 706 described in Fig. 7A .
  • a flat panel such as the panel 706 described in Fig. 7A .
  • Fig. 7C is a top cross-sectional view of a storm window 720, which is similar to the storm window 710 described above. Different from the storm window 710, the storm window 720 is constructed of a panel having a generally straight portion 726 and a generally curved portion 727. Similarly, Fig. 7D is a top cross-sectional view of a storm window 730 that includes two curved portions, 735, 737, curved in opposite directions, and having a relatively straight portion 736 therebetween. Various uses of storm windows having curved sections are described below with reference to Figs. 8A and 8B .
  • top may as well be referred to as “side,” depending on which orientation the storm window is inserted into the window frame, as described in detail below.
  • Fig. 8A is a front view of a storm window 820 having two curve points, 822 and 824.
  • the curve points 822, 824 are similar to the areas of curvature illustrated with reference to Fig. 7D above.
  • the storm window 820 is illustrated as being mounted within a window frame 840, and being held in place by resilient sections 830, 832, 834, and 836 as described above.
  • the curvatures in the panel of the storm window 820 marked by the curve points 822 and 824 are in opposite directions, though not illustrated in Fig. 8A .
  • the portion of the panel above the curve point 824, near the top of the window frame 840 is curved inward, toward the inside of a house Similarly, the portion of the panel below the curve point 822 is curved outward, toward the outside of the house.
  • Such a construction and installation of the storm window 820 of Fig. 8A within the window frame 840 provides a number of advantages, the most important of which is a controlled blowout feature.
  • the storm window is mostly likely to release pressure by the top portion of the window 820 moving toward the inside of the house, while the bottom portion and side portions remain relatively stationary. This happens because the curvature of the panel along the horizontal dimension, at the curve points 822, 824, stiffens the panel of the storm window 820 along its horizontal plane.
  • the vertical dimension has no additional stiffening measures, therefore, under a force from blowing wind, it is more likely that either the top or bottom edges 836, 832 of the window illustrated in Fig. 8A fails before the side edges 830, 834.
  • the portion of the panel 820 above the curve point 824 is already curved inward, toward the house, while the portion of the panel below the curve point 826 is curved outward.
  • This configuration makes the top edge 836 of the storm window 820 more likely to move under pressure than the bottom edge 832. It is desirable to force a top edge of a storm window to release before the bottom edge of a window for a number of reasons.
  • Fig. 8B is similar in many respects to Fig. 8A , however the window in the window frame 870 covered by storm window 850 is a horizontal window, rather than a vertical window in Fig. 8A .
  • the storm window 850 may include only one curve point 852 or two curve points 852, 854.
  • the storm window 850 of Fig. 8B includes both curve points 852, 854, both of the sections of the storm window beyond the curve points may bend inward toward the house.
  • the windows can be installed in either a horizontal or vertical orientation.
  • Fig. 9A illustrates another system for pre-disposing one or more portions of a storm window to release from its set position in a window frame before other portions.
  • a resilient support section 910 includes a bulb portion 903 and a groove portion 907.
  • the resilient support section 910 includes a series of friction ribs 911 coupled to the bulb portion 903.
  • the friction ribs 911 may be made from the same material as the resilient support section 910 or may be made from another material. If made from another material, the friction ribs 911 are attached to the resilient support section 910 by appropriate methods, such as adhesive or thermal welding.
  • the friction ribs 911 may be designed so that they provide more frictional force in one direction than another. For instance, with reference to Fig. 9B , it is easier to insert the resilient support section into the window frame, such as during installation, than removing it from the window frame, such as during a wind event. This increased frictional force is due to the shape and positioning of the friction ribs 911.
  • the friction ribs 911 may be relatively long and thin, or, with reference to Fig. 9C , the friction ribs 912 may be relatively large and relatively "chunky". In either case the ribs 911, 912 may be angled in a certain direction relative to a vertical plane of the resilient support section 910. This angling, along with the physical structure of the ribs 911, 912 causes the friction difference depending on direction of movement of the resilient support section 910.
  • Other designs of friction ribs are described below with reference to Figs. 16A-16C .
  • the bulb portion of a resilient support section for example the bulb portion 103 in Fig. 1 can take any shape, and need not be circular in cross section.
  • the hole illustrated in Fig. 1 may be filled with material that may change the reformation force of the resilient support sections. Changes in shape, thickness, material selection and the presence or absence of holes, for instance, in the resilient support can change the reformation force of the resilient support when it is holding a storm window in place.
  • the hole in the resilient support on the sides of a storm window installation may be filled with a material that has more restorative force than that the material filling the hole in the resilient support attached to the top and bottom of the storm window.

  • Various foams or other fillers used inside the hole of the resilient support may have different "compression set" values, which is the percent of original size a material will be restored to after deformation. Therefore, choosing materials having different compression set values to fill the hole in the resilient support allows the designer or builder choices for a material suitable for the particular installation.
  • a resilient support having ribs 911 or 912 of Figs. 9A or 9B may be employed in only those portions of the storm window where extra friction is desired.

  • the strap 1130 then exerts pressure on the retaining strap 1140 ( Fig. 15C ), and, depending on the diameter of the hole 1134, on the stud cap 1142 as well.

  • the strap 1130 is affixed to the panel 1110 by virtue of the snap post 1120 and other portions of the system.

Then the user may open the outside window as if the storm window had not been put in place.

  • a surface may be placed against the top of the soft-bulb portion 1901 of Fig. 19A , and the soft-bulb portion 1901 may be compressed to various amounts in a direction parallel to the vertical centerline 1903. Those various amounts may be, for example, increments of 1.59mm (1/16 of an inch).

  • the slip force metric should be sufficiently high enough to help prevent the secondary panel from dislodging from the window frame under typical conditions. For example, as noted above, when forceful winds blow from outside the window through air gaps in older windows, they may create significant pressure on the secondary window mounted inside. On the other hand, the slip force metric should be sufficiently low enough to help prevent the buildup of air pressure between the secondary panel and the existing window. As discussed above, that can also dislodge the secondary panel from dislodging from the window frame. Accordingly, it is preferred that the slip force changes relatively little as compression of the bulb increases.
  • Secondary panel systems incorporating an assembly may have a slip force that increases less than 50% as the bulb compression increases from about 10% of overall bulb height to about 65% of overall bulb height.
  • some conventional panel systems have a slip force that increases over 400% for the same compression interval.
  • the push force is the force, per unit area, that it takes to dislodge a mounted secondary panel from a window frame. In other words, it is a measure of the resistance to air pressure acting, or pushing, on the panel.
  • pull force is a measure of the effort it takes to dislodge the panel by pulling it, from a localized point on the panel, rather than pushing it.
  • the pull force may quantify how difficult it would be for a user to intentionally dislodge the mounted panel from a window frame by pulling on the panel.
  • the pull force and push force are generally determined relative to a frame depth, which is how deep into a window frame the panel, including the bulb and the carrier, is mounted.
  • secondary panel systems incorporating an assembly such as the assembly 1900, may have a push force that is about 5.2 pounds per square foot and a pull force of about 10.5 pounds on a panel having an area of about 3.5 square feet.
