The disclosure relates in general to a window bracket, and more particularly, to a composite window bracket.
In the past, in order to provide a highly thermally efficient (metal) wall or (metal) roof assembly for a building enclosure, it has been necessary for metal materials, typically an exterior and interior metal skin, to be bonded to either side of an insulated panel core inside a factory thereby creating a foam panel. These metal skins are typically profiled and have offsets in them to prevent the exterior metal skin from contacting the interior metal skin. This is done in an effort to prevent metal to metal contact thereby reducing thermal conductivity from the outside of the building. Heat travels in the path of least resistance such that heat can invade a system and affect an interior atmosphere through relatively finite pathways such as fasteners and the like that have metal to metal contact with exterior conditions. Similarly, exterior exposure to cold temperatures can allow for infusion of cold temperatures into a wall construction along highly thermally conductive components.
Most applications of metal roof and wall assemblies retain at least some form of metal to metal contact through metal anchors, fasteners, or sill, transition, and window trim. Products of this type are subject to shorter warranties and life cycles due to the fact that the product is glued or otherwise bonded and is subject to damage and shortened life spans from thermal cycling which causes varying rates of contraction and expansion of the different materials and therefore wears significantly on any given system. Furthermore, these systems often require dissimilar materials to be in contact with each other which can lead to reactions such as oxidation which can corrode these materials over time. A metal wall, roof or deck system that creates a thermal break in the heat conductivity path thereby effectively eliminating or greatly reducing thermal bridging from exterior conditions to interior conditions that keeps like materials separate is desired.

While this disclosure is susceptible of embodiment in many different forms, there is shown in the drawings and described herein in detail a specific embodiment(s) with the understanding that the present disclosure is to be considered as an exemplification and is not intended to be limited to the embodiment(s) illustrated.
It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of the invention, and some of the components may have been distorted from actual scale for purposes of pictorial clarity.
Referring now to the drawings and in particular to
The second member 120 includes a first end 121 and a second end 122, the first end 121 and the second end 122 being on opposite ends of the second member 120. The second member 120 further includes a first surface 123 extending from the first end 121 to the second end 122, and a second surface 124 extending from the first end 121 to the second end 122. As shown, the first surface 123 is on an opposite side of the second member 120 as the second surface 124. In at least one configuration of the composite window bracket 100, the first surface 123 is approximately 2 inches in width.
In at least one configuration, where the second surface 114 of the first member 110 meets the second surface 124 of the second member 120 can be rounded thereby forming a rounded inside corner 160 for the composite window bracket 100. Such a rounded inside corner 160 increases a rigidity of the composite window bracket 100 with added material from which the composite window bracket 100 is manufactured being included in the rounded inside corner 160. In at least one configuration, where the first surface 113 of the first member 110 meets the first surface 123 of the second member 120 can be squared thereby forming a square outside corner 161 for the composite window bracket 100. The square outside corner 161 also increasing a rigidity of the composite window bracket 100 with added material from which the composite window bracket 100 is manufactured. Such a squared outside corner 161 allows the second end 112 of the first member 110 to sit flush against a support beam 1510 (
At least one of the first member 110 and the second member 120 further includes at least one accessory member coupled thereto to couple the composite window bracket 100 to at least one accessory bracket. Although the accessory member can take on various configurations,
In at least one configuration, the composite window bracket 100 further includes another accessory member, such as a second accessory member 150. The accessory member 150 is substantially of a same configuration as the accessory member 140. The accessory member 150 can be coupled to the second surface 114 of the first member 110. The accessory member 150 can be disposed substantially equidistant between the first end 111 and the second end 112 of the first member 110, although other locations are possible.
In at least one configuration, the composite window bracket 100 can further include another accessory member, such as accessory member 130. The accessory member 130 is coupled proximate to the first end 121 of the second member 120. As will be discussed in more detail below, the accessory member 130 can be coupled to at least one of a fire suppression bracket, a rigidity bracket, a window retention bracket, or any other bracket, various example configurations of which are discussed below.
In at least one configuration, the accessory member 130 can be “L” shaped and include a first portion 131 that is substantially perpendicularly coupled to the second surface 124 of the second member 120, proximate to buy not fully at the first end 121 of the second member 120. The accessory member 130 can further include a second portion 132 substantially perpendicularly coupled to an opposite end of the first portion 131 from which the first portion 131 is coupled to the second surface 124 of the second member 120, the second portion 132 extending in a same direction as the first end 121 of the second member 132. The first end 121 of the second member 120 and the second portion 132 of the accessory member 130 thereby form a slot 133 therebetween, the slot 133 including a substantially planar back surface 134 that is substantially perpendicular to the second surface 124 of the second member 120. The slot 133 includes angled ends 135 such that the slot 133 tapers from the back surface 134 to an opening of the slot 133, as shown.
In at least one configuration, an accessory member can be coupled to the second member 120, such as the accessory member 140. The accessory member 140 is coupled to the second surface 124 of the second member 120. The accessory member 140 is disposed substantially equidistant between the first end 121 and the second end 122 of the second member 120, although other locations are possible. In at least one configuration, the accessory member 140 can be a tab that is approximately a third of the width of the second member 120. The accessory member 140 is a substantially flat member that includes angled ends 141 that taper towards the second surface 124 where the accessory member 140 couples to the second member 120. In at least one configuration, the composite window bracket 100 can further include another accessory member 150, instead being coupled substantially centrally to the second surface 114 of the first member 110.
Typically, the composite window bracket 100 and a bracket 1540 (
The composite window bracket 100 and the bracket 1540 provide a thermal break. As used herein, the term “thermal break” refers to a break in like materials wherein the material disposed between like materials is comprised of a material having low thermal conductivity such as a polymeric material having a high R-value as further described below. R-values are measurements of the thermal resistance of different materials. R-values are well known by those skilled in the art of the construction and insulation industries. A high R-value indicates a highly insulative material, such as an R-value of R0.2 per inch and higher. Conductive materials have a very low R-value, such as steel which exhibits a negligible or nearly non-existent R-value. In the configuration of the present disclosure, there are no like materials in contact with one another, nor is there any metal to metal contact creating a pathway for heat to transfer from the exterior to the interior and vice versa.
It is also contemplated that the composite window bracket 100 and a bracket 1540 can comprise anticorrosive polymeric materials that exhibit high insulative qualities or rather, demonstrate high R-value properties such as an R-value in the range of about R0.2 to about R8 per inch. Polymeric materials suitable for the present disclosure include thermoplastics or thermoset resin materials including for example: acrylonitrile-butadiene-styrene (ABS) copolymers, vinylesters epoxies, phenolic resins, polyvinyl chlorides (PVC), polyesters, polyurethanes, polyphenylsufone resin, polyarylsulfones, polyphthalimide, polyamides, aliphatic polyketones, acrylics, polyxylenes, polypropylenes, polycarbonates, polyphthalam ides, polystyrenes, polyphenylsulfones, polyethersulfones, polyfluorocarbons, bio-resins and blends thereof. Other such thermoplastics and thermoplastic resins suitable for the present disclosure are known in the art which demonstrate high R-values and are thereby heat resistant as well as anticorrosive.
Thermoplastics of the present disclosure are also contemplated using a recyclable polymer or are made of a polymeric material which is partially comprised of a renewable resource such as vegetable oil or the like in its composition when an eco-friendly or “green” composite window bracket 100 and the bracket 1540 are desired. The polymeric material of the present disclosure can also be reinforced with a reinforcing fiber as detailed herein. The composite window bracket 100 and the bracket 1540 composed of the materials discussed above form a thermal break between exterior panels and building substrates (e.g., a support beam 1510) in an effort to control the temperature within a building structure by reducing or eliminating thermal conductivity from the exterior panel to the building substrate and vice versa. In assembly, the R-value of an exterior wall panel system of the present disclosure can typically exhibit a R-value from about R0.2 to about R30 per inch depending on the thickness of the overall system, the insulation materials used and the composition of an insulation 1545 (
Regarding the R-value of the composite window bracket 100 and the bracket 1540 of the present disclosure, a relatively high R-value is desired to ensure adequate insulation of a building structure from outside elements by making the composite window bracket 100 and the bracket 1540 create a thermal break in a wall system. A range of R-values for the polymeric materials used to construct the composite window bracket 100 described above would be a range of about R0.2 to about R8 per inch in order to create a thermal break that effectively reduces or eliminates thermal bridging. The thermal conductivity, or K-value, is the reciprocal of the material's R-value, such that for a polymeric material exhibiting an R-value of about R0.2 to R8 per inch, the correlating K-value for that material would be from about K5 to about K0.125 per inch. Thus, in comparison to present day metal components used in other insulation systems made of iron or steel, a polymeric bracket member of the present disclosure will exhibit a K-value of approximately about K0.5 to about K0.125 per inch at a given set of conditions as compared to components made from a metallic material such as iron or steel which would have an approximate K-value as high as K32 to K60 per inch at the same conditions. This is because metallic materials, such as iron and steel, have low or negligible R-values and are well known conductors of heat. Steel is known to have an R-value of about 0.003R per inch. Thus, for example, a steel clip compared to a polymeric bracket of the present disclosure having an R-value of R0.55 would be 183 times more thermally conductive.
There are several different types of measurements that relate to a materials ability to insulate, resist, transmit or conduct heat across a material. Particularly, a material's K-value relates to a specific material's thermal conductivity, a material's C-value correlates to the material's thermal conductance, a material's R-value relates to a material's thermal resistance, and a U-value relates to the thermal transmittance of an overall system. In designing a wall, roof or deck bracket and panel system providing adequate insulative properties for a building structure, materials with low K-values and C-values are desired while materials with high R-values are desired. When this set of conditions is met, the overall thermal transmittance, or U-value, of the system is low. Thus, the lower the U-value, the lower the rate heat thermally bridges from one material to another. A building structure having a well-insulated system will have a much lower U-value than an uninsulated or poorly insulated system exhibiting high thermal transmittance.
The second member 220 likewise includes a first end 221 and a second end 222, the first end 221 and the second end 122 being on opposite ends of the second member 220. The second member 220 further includes a first surface 223 extending from the first end 221 to the second end 222, and a second surface 224 extending from the first end 221 to the second end 222. As shown, the first surface 223 is on an opposite side of the second member 220 as the second surface 224. Each of the first and second members 210, 220 include slots 240, respectively, that are configured to match shape configuration (width, curvatures, planar portions) of the accessory members 140, 150, discussed above, such that the accessory members 140, 150 slide snuggly into the slots 240. That is, the slots 240 are each configured similar to slot 133, although in at least one configuration they can be wider than slot 133, discussed above to include a substantially planar back surface 134 and angled ends 235 that angle opposite angled ends 141 of the accessory members 140. The accessory bracket 200 further includes a rounded outside corner 260 where the second end 212 of the first member 210 and the second end 222 of the second member 220 meet. This rounded outside corner 260 matches a configuration of the rounded inside corner 160 of the composite window bracket 100, to allow these corners 160, 260 to sit flush once coupled.
The second member 420 includes a first end 421, a second end 422, a first side 423 and a second side 424. The second end 419 of the third portion 413 is substantially perpendicularly coupled to the second end 422 of the second member 420. The second member 420 further includes a tab 450, the tab 450 including a substantially flat surface 451 that runs parallel to the second side 424 of the second member 420. The tab 450 also includes angled ends 455 such that ends of the tab 450 taper towards the first side 423, thereby being configured to correspond to the angled ends 123 of the slot 135 of the composite window bracket 100, the tab 450 slidable snuggly into the slot 135.
The second member 1120 is an “L” shaped member that includes a first portion 1121 and a second portion 1122. The first portion 1121 includes a first end 1123 and a second end 1124. The first portion 1121 is coupled to the second portion 1112 of the first member 1110 and proximate to the second end 1117 of the first member 1110. The second portion 1122 includes a first end 1125 and a second end 1126 that is substantially perpendicularly coupled to the second end 1124 of the first portion 1121. The first portion 1121 further includes the tab 450 coupled substantially centrally on a side of the first portion 1121 facing the first portion 1111, as shown. When the accessory bracket 1100 is installed onto the composite window bracket 100, the first portion 1111 is disposed within a recess or slot in a frame of the window 1520 to secure the window 1520 to the accessory bracket 1100.
During installation of the composite window bracket 100, the first surface 113 of the first member 110 is to be coupled to the support beam 1510. That is, the composite window bracket 100 is aligned with an opening (not shown) in which the window 1520 is to be disposed. The first surface 123 of the composite window bracket 100 is aligned with this opening such that the first surface 123 and the opening form a substantially horizontal planar surface, such as that shown in
During installation of any of the accessory brackets 200-1200, the accessory brackets 200-1200 are slid onto either ends 1711, 1712 (
In at least one configuration, the accessory brackets 200-1200 and an accessory bracket 1300 (
In more detail, the insulation 1545 can also be fire retardant panels, sound dampening panels or any other type of insulating material or panel known in the art for providing an interior or exterior wall with a quality for which the panel is known. Other such insulating materials or panels include materials having additives like insecticides, fungicides or colorants for example, though many types of insulating materials are known in the art. For the purposes of the description below, as depicted in the accompanying figures, they are exemplified as panels, which may be sealed or unsealed, designed to insulate the building structure. Sealed panels provide a vapor barrier in the wall construction of the present disclosure. Other insulating materials suitable for use with the insulation 1545 include, but not be limited to, foam, fiberglass insulation, rigid insulation, semi rigid insulation, blanket insulation, loose fill insulation, spray foam in either fiberglass, rock wool, cellulose based, polystyrene, polyisocyanurate, polyurethane or other polymeric insulation formulations.
As an example configuration, system 1500 includes the accessory bracket 800 disposed within the slot 133 of the composite window bracket 100. As shown, the cladding 1550 can be disposed under the accessory bracket 800 and the cladding 1560 can be disposed against the second side 814 of the accessory bracket 800. To assist with securing the cladding 1560 against the cladding 1550, another type of bracket, bracket 1570 can be disposed atop the cladding 1560, atop the accessory bracket 800, atop the first end 121 of the composite window bracket 100, and into a slot 1521 within the window 1520.
