DETAILED DESCRIPTION
[0051] Various aspects of the present application will evolve from the following detailed description of the preferred embodiments which should be taken in conjunction with the prior delineated drawings.
[0052] The invention as a whole is shown in the drawings by reference character 10, with various embodiments denoted with the addition of an uppercase letter.
[0053] Referring now to FIG. 1, it may be observed that an embodiment 10A of a perimeter extrusion is shown in whole.
[0054] Embodiment 10A includes an arm 12 terminating in an end portion 14. End portion is formed with prongs, fins, or tips 16 and 18, generally on the form of “fishtail”. End portion 14 is employed to engage a panel 20, shown in phantom in FIGS. 1-8. Panel 20 includes removed portions to facilitate bending by end portion 14 of arm 12 of device 10A, which is best illustrated in FIG. 9A. Device 10A is also provided with a platform 22 which is contiguous with arm 12 and spaced therefrom to form a slot 24. Wall portion 26, surrounding slot 24, includes a serrated surface 28, which is used to grip part 30 of panel 20. It should also be noted that end part 32 of panel lies across end portion 14 of device 10, contacting prongs 16 and 18.
[0055] Device 10 further possesses a shelf 34 which is intended to hold a reveal strip 36. Again, reveal strip 36 is shown in FIGS. 1-8 in phantom, and is best shown as a whole in FIG. 9C and FIG. 11. Device 10A is further constructed with a leg 38, which is intended to connect to the facade of the structure via a base member, which will be discussed hereinafter, and is best shown in FIG. 11. Flange 40 projects from device 10 in a direction opposite to shelf 34, the function of which will be discussed as the specification continues. It should be realized that arm 12, platform 22, shelf 34, leg 38, and flange 40 are contiguous in device 10A.
[0056] Turning now to FIG. 2, embodiment 10B of the perimeter extrusion is depicted. Device 10B is similar to device 10A except that leg 42 includes an end portion 44, which is compatible with prior art fixation mechanisms used to attach embodiment 10B to a facade. For example, end portion 44 may be employed with the fixation mechanism shown in U.S. Pat. No. 9,903,123, which is incorporated by reference as a whole. Also, a shelf 46 is included which extends from embodiment 10B and is slightly tilted upwardly to provide support for reveal strip 36 against end part 30 of panel 20. In addition, a spacer 47 extends from slot 24 to maintain frictional engagement between panel 20 and reveal 36.
[0057] FIG. 3 reveals another embodiment 10C of the device of the present application in the form of a perimeter extrusion in which an arm 48 includes an end portion 50 having a corner 52 that, again, allows for the easy bending of panel 20. Elbow 33 also serves to further bend panel 20 to form end part 30. Again, end part 30 of panel 20 lies in a slot 54 and a shelf 56 supports reveal strip 36. Leg 58 is similar to leg 38 of FIG. 1. A fastener 60 is shown as being an option to hold end part 30 of panel 20 within slot 54.
[0058] FIG. 4 shows another embodiment 10D of a perimeter extrusion of the device of the present application. Embodiment 10D possesses an end portion 62, which is similar to end portion 48 of embodiment 10C of FIG. 3. Slot 64 includes a serrated surface 66 and a wall 68 having a turned end 70. Wall 72 extends outwardly from leg 74 and holds reveal strip in place with turned end 70 of wall 68.
[0059] FIG. 5 illustrates another embodiment 10E of the perimeter extrusion of the device of the present application in which a leg 76 terminates in a prong 78 that allows the bending and forming of portions 30 and 32 of panel 20. Portion 30 fits within slot 80 having a serrated surface 82. An insulated element 84 lies adjacent part 32 of panel 20 and under surface 86 of panel 20. Corner 86 of insulated element 84 aids in the bending of panel 20, although a second prong similar to prong 78 may be extended upwardly to substitute for corner 86 of insulated element 84. Flange 88 projects outwardly from shelf 84. Leg 90, similar to leg 74, FIG. 4, extends downwardly for connection to a base member, to be described hereinafter.
[0060] Viewing now FIG. 6, another embodiment 10F of the perimeter extrusion of the device of the present application is shown. Device 10F shows a leg 92. Leg 92 includes prongs or fins 94 and 96, which are spaced apart from each other a greater distance than the prongs depicted in FIG. 1 with respect to embodiment 10A. Thus, panel section 98 is formed creating a greater depth for the placement of reveal strip 36 on shelf 100. Slot 102 takes a form similar to slot 80 of FIG. 5.
[0061] FIG. 7 reveals another embodiment 10G of the perimeter extrusion of the device of the present application in which arm 104 possesses an end portion 106 which is approximately hemispherical. Panel 108 is formed with a removed or relieved portion 110, which is created by any suitable mechanical tool, such as a router. Panel 108 is then bent around end portion 106 to create an end part 114 that fits within slot 112. Directional arrow 116 indicates such bending action while directional arrow 118 shows the downward positioning of panel 108 around leg 104. Leg 120 and flange 122 are similar in structure to such elements shown in FIG. 1 with respect to embodiment 10A.
[0062] Looking at FIG. 8, another embodiment 10H of the perimeter extrusion of the device of the present application is depicted. Device 10H is made with an arm 124 and is used in conjunction with panel 108 of FIG. 7. End portion 126 of arm 124 is approximately T-shaped and allows the bending of panel 108 around arm 124 such that panel and part 112 fits within slot 128.
[0063] FIGS. 9A-9C delineate the steps involved in the operation of the bending and securing of a panel 130 causing a perimeter extrusion similar to the extrusion depicted as embodiment 10A of FIG. 1. Consequently, the elements of the extrusion shown in FIGS. 9A-9C will bear the same reference characters shown in FIG. 1. Panel 130 is formed with an end part 132 which lies adjacent to a relieved or removed portion 134. Removed portion 134 possesses crevices 136 and 138. Initially, end part 132 of panel 130 is placed in slot 124 such that crevice 138 bears against prong 18 of end portion 14 of arm 12, FIG. 9A. FIG. 9B shows the turning, bending, or folding of panel 130 such that channel 136 contacts prong 16 of arm 12. Directional arrow 140 indicates the turning, bending, or folding movement of panel 130. FIG. 9C shows panel 130 in its finished condition after panel 130 has been folded via prong 16 in crevice 136, such that panel part 132 lies within slot 24 and panel part 142 lies against prong end portion 14 of arm 12. Thus, perimeter extrusion 10A serves as a folding tool that remains adjacent panel 130 after employment. It should be noted 16 that an optional double sided tape layer 142 is pictured as lying atop shelf 34, FIGS. 9B and 9C, in order to rest against reveal strip 36 placed on shelf 34, according to directional arrow 144, FIG. 9C. Also, double-sided tape or caulk may be inserted between arm 12 and the underside op panel 130 to stabilize movement therebetween.
[0064] FIG. 10 illustrates the side portion of leg 38 of embodiment 10A of FIG. 1 and other legs of embodiments 10B-10H that are similar in FIGS. 2-8. Apertures 146 and 148 are shown as well as opening 150 therethrough. Apertures 146 and 148 as well as opening 150 are intended to interact with base 152 shown in FIGS. 11 and 12. Base or channel 152 is held to facade 154 by a positioning fastener 156. Base 152 includes bottom surface 157 and extending walls 159 and 161. A locating groove 158 in surface 157 aids in the placement of fastener 156 at the base 160 of channel 152. Grooves 162 and 164 along walls 159 and 161, respectively, aid in marking the placement of clevis pin 166, which extends through a drilled hole (not shown) through base 152. Clevis pin 166 is exemplary of a multiplicity of clevis pins which may be used along channel 152. It should be noted that the apertures 146 and 148 of FIG. 10 of leg 38 are intended to interact with clevis pin 166 as well as others used therein. It should also be realized that the placement of fastener 156 forms a gap “A”, FIG. 12, between leg 38 and 17 channel 152. Thus, leg 168 of device 10A 1 is fixed such that the thermal expansion and contraction of panel 20 1 is confined to directions along arrow 170, since leg 168 is held between channel 152 and positioning fastener 156. In other words, fastener 156 prevents movement of leg 168 outside gap “A”. Of course, other positioning fasteners may be used along groove 158 to maintain this confinement of extrusion panel 10A 1. The same holds true for other panels used in the system depicted in FIGS. 11 and 12, including, panel 20, which is held to a similar channel to channel 52 (not shown) and is thus allowed to expand according to directional arrow 172. A frame 174 may be formed with perimeter extrusions 176, 178, 180, and 182, FIG. 13. Each perimeter extrusion, as shown in FIG. 13, is similar to the embodiment depicted as 10A in FIG. 1. It should be also seen that flanges 184 of perimeter extrusions 176 and 178 overlap each other at the corner 188 of frame 174. Fasteners may be used at such overlay location to hold perimeter extrusions 176 and 178 together (not shown). Such flanges correspond to flange 40 of FIG. 1. Perimeter extrusions 176, 178, 180, and 182 are also depicted without attached panels and apertured side portions of legs for the sake of simplicity. Stiffeners 190 and 192 may also be used with frame 174 and are positioned flat side-to-flat side thereat. An optional fastener 194, may also be employed to fix stiffeners 190 and 192 to each other and to facade 154. Also, fasteners may be employed to hold stiffeners to perimeter extrusions 176, 178, 180, and 182. Exemplar flange 184 of perimeter extrusion 176 may be used for this purpose.
[0065] Turning to FIG. 14, it may be observed that panels 196, 198, and 200 are positioned in overlapping configuration along a vertical facade 202. Perimeter extrusions 202, 204, and 206 support panels 196, 198, and 200 in this position, and are held to facade 202 by fasteners 208, 210, and 212.
[0066] In operation, any one of the perimeter extrusions 10A-10H of FIGS. 1-8 may be employed with properly routed panels such as panel 20. With reference to FIGS. 9A-9C, it may be observed that a panel 130, similar to panel 120, is used and fits within slot 24. Crevice 138 of panel 130 also bears against prong 18 of end portion 14 of arm 12 of embodiment 10A. Panel 130 is then raised upwardly to effect the first bend such that prong 16 contacts crevice 136 and then is further bent such that the remainder of panel 130 lies atop arm 12 when panel 130 is bent over prong 16. Reveal 36 is then slipped below portion 132 of panel 130 on shelf 134. Double sided tape 142 may be optionally used to further fix panel 130 in place. Once assembled, perimeter extrusions 10A-10H firmly hold any panels, such as panel 20, in place at facade 154.
[0067] While in the foregoing embodiments of the application have been set forth in considerable detail for the purposes of making a complete disclosure of the application, it may be apparent to those of skill in the art that numerous changes may be mad in such details without departing from the spirit and principles of the application.
