Referring to
In some prior panel assemblies, a perimeter extrusion is fastened to a panel sidewall by placing the perimeter extrusion against the panel sidewall, and drilling a plurality of holes into the perimeter extrusion through the panel sidewall, inserting a rivet into each hole, and then expanding each rivet to permanently fasten the perimeter extrusion to the panel. However, the drilling step can add considerable labor costs to the panel assemblies, and create waste drillings which can ruin panels with scratches as they are handled on a work surface. In one aspect, perimeter extrusion 112 may be free of drilled holes, which may reduce labor costs and waste panels in the manufacturing of panel assemblies 100.
Each panel 108 may include a panel front wall 116 and one or more panel sidewalls 120 extending along a periphery of the panel front wall 116. In the illustrated example, panel front wall 116 is rectangular having four side edges 124, and two panel sidewalls 120 extend along two of the side edges 124 opposite one another. In alternative embodiments, panel front wall 116 may take any suitable shape. For example, panel front wall 116 may have a regular shape (triangular, pentagonal, etc.) or an irregular shape (e.g. a multi-sided polygon). Further, panel 108 may include any number of panel sidewalls 120. Panel sidewalls 120 may extend about a fractional portion of the periphery of panel front wall 116, or about substantially the entire periphery of panel front wall 116. For example, panel front wall 116 may include additional panel sidewalls 120 extending along the remaining two side edges 124 shown without panel sidewalls 120.
In the illustrated embodiment, panel front wall 116 is integrally formed with panel sidewalls 120. For example, panel front wall 116 and sidewalls 120 may be formed as a continuous sheet of material with peripheral regions that have been bent to form panel sidewalls 120. In other examples, panel 108 including panel front wall 116 and panel sidewalls 120 may be integrally formed by casting or extrusion. In alternative embodiments, one or more of panel sidewalls 120 may be separately formed and connected to panel front wall 116. For example, one or more of panel sidewalls 120 may be connected to panel front wall 116 by adhesive, fasteners (e.g. rivets, screws, bolts, or nails), or by welding.
Panel front wall 116 and sidewalls 120 may be formed of any suitable material(s), such as metal, plastic, stone, or glass. Panel front wall 116 may be formed of the same or different material than panel sidewalls 120. Panel sidewalls 120 may be all formed of the same material, or one or more of panel sidewalls 120 may be formed of different material(s) than other panel sidewall(s) 120.
In some embodiments, panel 108 may formed of multiple layers of material. For example, one or more of panel front wall 116 and panel sidewalls 120 may be formed of multiple layers of material. As shown, each of panel front wall 116 and panel sidewalls 120 may include an outside face 128, which may be visible when panel 108 is mounted to a building wall, and an inside face 132. One or more of panel front wall 116 and panel sidewalls 120 may include an outside layer 136 which forms the outside face 128, and an inside layer 140 which forms the inside face 132. In the illustrated example, each of panel front wall 116 and panel sidewalls 120 is a trilaminate including an outside layer 136, an inside layer 140, and a core 144 between the inside and outside layers 136 and 140. The layers 136 and 140, and the core 144 may be the same or different materials. For example, the outside and inside layers 136 and 140 may be a metal such as aluminum or another material, and the core 144 may be a plastic material such as polyethylene or another material. Alternatively, all three layers 136, 140, and 144 may be the same material, whether a metal, plastic, or another material (e.g. glass or stone).
One or both of the outside and inside faces 128 and 132 may be coated by paint, a laminate, an anodized layer, or another type of coating. For example, a coating imparting particular color(s) and/or texture(s) may be applied to the outside face(s) 128 of panel front wall 116 and/or sidewalls 120. Alternatively, one or both of outside and inside faces 128 and 132 may be uncoated bare material.
As shown, panel front wall 116 may be substantially planar, and panel sidewalls 120 may extend rearwardly substantially perpendicular to panel front wall 116. In alternative embodiments, panel front wall 116 may have a non-planar surface profile. In some embodiments, panel sidewalls 120 may extend rearwardly of panel wall 116 at a non-perpendicular angle (e.g. at 60 to 120 degrees to panel front wall 116).
Mounting a panel 108 to a building wall may include fastening anchor extrusions 104 to the building wall (e.g. with concrete screws or by another suitable method), fastening perimeter extrusions 112 to panel 108, and then mounting perimeter extrusions 112 onto anchor extrusions 104. Perimeter extrusions 112 may be fastened to panel 108 by fasteners. In the illustrated example, perimeter extrusions 112 are fastened to panel 108 by rivets 148. In alterantive embodiments, perimeter extrusions 112 may be fastened to panel 108 by screws (not shown). In some embodiments, perimeter extrusions 112 may be free of drilled openings which may reduce or eliminate drilling labor costs and ruined panels from scratches by waste drillings.

Rivet 148 may have any suitable rivet head 272. In the illustrated embodiment, rivet 148 has a flat countersunk rivet head 272, which seats in the countersink of fastener opening 264. This may permit rivet 148 to be flush or recessed in fastener opening 264. In alternative embodiments, rivet head 272 may be button, pan, or cone shaped for example. As shown, rivet head 272 may have a width 284 greater than fastener slot 164.
Rivet 148 may have any suitable rivet body 268. In some embodiments, rivet body 268 may single expanding, or be double expanding to produce two bulges along its length. For example, rivet body 268 may have two expansion rings 288 to define a first expandable portion 292 between mandrel head 296 and the first expansion ring 288, and a second expandable portion 304 between the first and second expansion rings 288. Each expandable portion 304 may expand radially and engage with slot walls 192 and 196 of fastener slot 164 when mandrel 276 is drawn through rivet body 268.
Rivet 148 may have any suitable length 308. In the illustrated embodiment, rivet length 308 is sized to permit rivet 148 to be inserted into its final position in fastener opening 264 and fastener slot 164 prior to expanding rivet 148. For example, rivet length 308 may be less than or equal to the thickness of panel sidewall 120 and slot depth 220 of fastener slot 164 combined. It will be appreciated that rivet length 308 may be greater than this sum where, for example, rivet head 272 is intended protrude from the outside face 128 of panel sidewall 120.
Rivet body 268 may have any suitable width 310. As shown in

As shown, serrated interior surface 316 may include a plurality of regularly spaced, symmetrically shaped, identical teeth 312. In alternative embodiments, spacing between teeth 312 may be patterned (e.g. increasing or decreasing) or irregular (e.g. random). In some embodiments, teeth 312 may be asymmetrically shaped. For example, teeth 312 may be sloped with a tip facing toward or away from slot outer end 204. In some embodiments, the plurality of teeth 312 may include a plurality of differently sized and/or shaped teeth 312. For example, the teeth on the serrated interior surface 316 of upper wall 192 may differ from the teeth on the serrated interior surface 316 of lower wall 196. Further, there may be a plurality of differently shaped and/or sized teeth 312 on the serrated interior surface 316 of the slot upper and/or lower walls 192, 196. Each tooth 312 may extend linearly along width 224 of fastener slot 164 in the direction of extrusion. As shown, serrated interior surface 316 and teeth 312 may extend the entire width 224 of fastener slot 164. Serrated interior surfaces 316 may include any suitable number of teeth. For example, serrated interior surfaces 316 may include between 2-200 teeth, or between 10-75 teeth. In the illustrated embodiment, each serrated interior surface 316 includes 12 teeth 312 for a combined 24 teeth in total for fastener slot 164.

Perimeter extrusion 112 may be formed in any suitable manner. In some embodiments, at least a portion of perimeter extrusion 112 is integrally formed, such as by casting or extrusion. Other portions of perimeter extrusion 112 may be connected in a suitable fashion such as by fasteners (e.g. screws, rivets, or nails), adhesives, or welds. In the illustrated embodiment, the entirety of perimeter extrusion 112 is formed by extrusion as a finished article. As shown, this may provide perimeter extrusion 112 with a constant cross-sectional profile along the entire width 232 (
It will be appreciated that serrated fastener slot 164 may permit permanent riveted assembly of panel assembly 100 without having to drill holes (or remove any material for that matter) from perimeter extrusions 112. This may mitigate the risk of scrap drillings scratching the outside face 128 of panel 108 during assembly, and may eliminate the labor required to drill into perimeter extrusions 112. In turn this may reduce material costs from ruined panels 108, reduce labor costs from drilling, and reduce assembly time.
