DETAILED DESCRIPTION OF THE INVENTION

[0015] Implementations of the invention provide a screen enclosure frame directed to an assembly of components for use as a frame of a screen enclosure, and in particular, as a base component of the frame. The base component 100 of the present disclosure is shown in the accompanying drawings. As shown in FIG. 1, the base component 100 comprises a lower element 200 and an upper element 300. The base component 100 may comprise a rigid and durable material, such as metal, and in particular, an aluminum alloy. The metal may be manufactured via extrusion techniques known in the art, and therefore, the extruded metal base component 100 may be extruded to any length required for the necessary size of the screen enclosure. The base component 100 may, alternatively, be manufactured from other high strength materials such as polycarbonates, plastics, composites, carbon fiber, and the like. The base component 100 may also be cast, milled, vacuum formed, or manufactured using known techniques, including combinations thereof.

[0016] The lower element 200 is shown isolated in FIGS. 2 and 3. The lower element 200 is adapted to engage a supporting surface upon which the screen enclosure rests. The supporting surface may be, but is not limited to, a floor comprising concrete, cement, wood, or other common building materials. In other embodiments, the supporting surface may be a support beam, a column, or ceiling, and may comprise concrete, cement, wood, or any other sturdy and strong material. The lower element 200 comprises two walls 220, one at each of the opposite lateral sides of the lower element 200. The walls 220 of the lower element 200 may have a top end and a bottom end. An intermediate floor 240 may be extend substantially perpendicular to and inward from the top ends of the walls 220. The intermediate floor 240 may have a substantially horizontal orientation and may comprise a recessed channel at a central distance between the two walls 220. The recessed channel may be defined by two channel walls 262, which may be substantially perpendicular to the intermediate floor 240, and a channel floor 264, which may be substantially parallel to the intermediate floor 240. In one embodiment, the channel floor 264 is approximately 0.5 inches below the intermediate floor 240. However, the depth of the recessed channel may range from between just slightly below the intermediate floor 240 to substantially the entirety of the distance between the intermediate floor 240 and the supporting surface.

[0017] The recessed channel may further comprise holes within the channel floor 264, whereby a screw may be fastened through the hole and into the supporting surface, securing the lower element 200 to the supporting surface. The recessed channel allows for the lower element 200 to receive the screw at a positon closer to the supporting surface, thereby shortening the amount of the screw that is not secured within the supporting surface. This shortening of the distance between a top portion of the screw that is secured through the hole of the lower element 200 and the supporting surface provides that less torque will be applied to the portion of the screw that is secured within the supporting surface when an outside force is applied to a side of the lower element 200. Therefore, the outside force, such as hurricane force winds, will be less likely to rip out or damage the connection between the screw and the supporting surface, allowing for less maintenance and a longer lifetime to the base component 100.

[0018] The recessed channel also provides that a lower amount of the screw will be exposed to the outside elements when the screw is secured within the supporting surface. Further, as distance between the secure point of the screw within the channel floor 264 and the supporting surface is shortened, a shorter screw may be used in connection with this embodiment of the base component 100 than is typically used with screen enclosures. Although, the use of a screw is disclosed above, any type of fastener known in the art may be used to secure the lower element to the supporting surface.

[0019] The lower element 200 further comprises at least two inner legs 270 extending downward from the channel floor 264. A bottom tip of the inner legs 270 is adapted to contact the supporting surface and provide support to the lower element 200, when the lower element 200 is fastened to the supporting surface through the hole in the recessed channel. The fastener is attached to the supporting surface through a hole at a position between the at least two inner legs 270. In one embodiment, the inner legs 270 are disposed on the channel floor 264 at a location inside and below channel walls 262. The shorter distance between the inner legs 270 compared to that of the channel walls 262 allows for additional support to the lower element 200 by preventing the collapse or buckling of the recessed channel and the inner legs 270 when the fastener is secured through the hole of the channel floor 264 to the supporting surface. In another embodiment, the inner legs extend downward from the channel floor 264 at a location directly below the channel walls 262. A third embodiment of the lower element 200 is shown in FIG. 7, whereby the lower element 200 comprises two sets of inner legs 270. A first set of the inner legs are positioned at a longitudinal location between the channel walls 262 and a second set of inner legs is positioned at a longitudinal location outside of the channel walls 262, thereby providing superior support for the lower element 200.

[0020] The lower element 200 further comprises at least two tabs 280 at opposite lateral ends of the intermediate floor 240. The tabs 280 are aligned with and adapted to engage protrusions 320 (as shown in FIG. 6) of the upper element 300, thereby securing the upper element 300 to the lower element 200. The tabs 280 may be able to flex inward when the protrusions 320 are forced down upon the tabs 280, and thereafter snap back into their original position, securing the protrusions 320 below the tabs 280. Alternatively, the protrusions may flex outward when forced upon the tabs 280, and thereafter snap back to their original position, securing the protrusions 320 below the tabs 280.

[0021] The upper element 300 is shown isolated in FIGS. 4 and 5. The upper element 300 comprises two sidewalls 340 at opposite laterals ends and a top floor 360 extending between upper ends of the sidewalls 340. In one embodiment the protrusions 320 of the upper element 300 are disposed at bottom tips of the sidewalls 340. However it is within the scope of this invention that the protrusions 320 may be disposed at any height on an inside face of the sidewalls 340 or the protrusions 320 may extend at any position downward from the top floor 360.

[0022] The upper element 300 is further comprised of a groove 380 disposed in at least one sidewall 340. Screen material of a screen enclosure typically comprises a spline that allows the screen material to be easily secured in a frame of a screen enclosure by the application of force. The groove 380 is adapted to receive a spline for securing screen material. The groove 380 may be disposed proximate the top floor 360. This location of the groove 380 provides the advantage of allowing only a minimal amount of the screen material and the base component 100 to come into contact. Contact between the screen material and the base component 100 may cause the screen to rip or be cut upon the metal surface due to friction or imperfections in the material of the base component 100. Further, the space between the screen material and the base component may trap dirt, sediment, and other unwanted material. The accumulation of this unwanted material may lead to the growth of bacteria or fungus, which may become unsightly or cause unpleasant odors, which require the replacement of the screen material itself.

[0023] In another embodiment, as shown in FIG. 6, a grove 380 may be disposed on both of the sidewalls 340 of the upper element 300. This allows for a symmetric configuration, which aids in the installation of the upper element 300 unto the lower element 200, as the orientation of the position of the groove 380 does not need to be specified. Screen material may be installed on either side of the lower element 200, or on both sides.

[0024] The upper element 300 offers the further advantage over existing devices by providing a more aesthetic finish to the base component 100 by covering and hiding the fasteners securing the lower element 200 to the supporting surface. Further, while the recessed channel may house the majority of a head of a fastener, if the head extends beyond the intermediate floor 240 of the lower element 200, the upper element 300 will effectively cover the remainder of the head of the fastener. The upper element 300 also prevents water and other debris from contacting the fastener within the recessed channel of the lower element 200, which prevents the fastener from potentially corroding and weakening the connection with the supporting surface.

[0025] In one embodiment, the upper element 300 and the lower element 200 are comprised of the same material. In other embodiments, the lower element 200 and upper element 300 may be comprised of different material, wherein the lower element 200 is comprised of a stronger material than the material of the upper element 300. For example, the lower element 200 may be comprised of a metal alloy, while the upper element may be comprised of a high-strength polymer. This may allow for lower costs and less overall weight of the base component 100.

[0026] In installing the base component 100, the lower element 200 is first secured to the supporting surface at a desired location. Upon the fastening of the lower element 200 to the supporting surface, the upper element 300 is aligned over the length lower element 200. Force is applied upon the upper element 300, forcing the protrusions 320 of the upper element 300 to clip under the tabs 280 of the lower element 200.
