DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

First Preferred Embodiment

[0014] FIG. 1 shows a first preferred embodiment of the present invention. Metal fence 10 includes posts 11 inserted into concrete footing 12. Cap 15 covers the top of posts 11. Top rail 13 and bottom rail 14 are slid into rectangular opening 14 of posts 11 (see also FIGS. 2 and 3). Metal boards 16 are slid into top rail 13 and bottom rail 14 as shown.

[0015] FIG. 4A shows a bottom view of bottom rail 14. Bottom rail 14 includes weep holes 18 for allowing water to drain and for providing ventilation. FIG. 4B shows a front view of top rail 13 and FIG. 4C shows a perspective view of top rail 13 with ventilation holes 19. FIG. 5 shows a top view of post 11. FIG. 6 shows a perspective view and FIG. 7 shows a side view of board 16.

[0016] Post 11, rails 13 and 14 and boards 16 are hollow and are all preferably fabricated from extruded metal. In a preferred embodiment, board 16 has a 1-inch6-inch cross section. Rails 13 and 14 each have a 2-inch4-inch cross section. And post 11 has a 4-inch4-inch cross section. Post 11, rails 13 and 14 and boards 16 are all preferably fabricated from galvanized steel to prevent corrosion and are preferably coated with a marine grade primer and industrial top coat for protection against the elements and rusting.

Preferred Method of Installation

[0017] Posts 11 are first set in concrete footings 12, as shown. After concrete footings 12 are cured, bottom rail 14 and top rail 13 are both slid into one post only. Boards 16 are then slid into the uninstalled ends of rails 13 and 14 until all the boards have been installed. Then, after all the boards have been installed, rails 13 and 14 are inserted into the other post 11.

Superior Strength Characteristics

[0018] Metal fence 10 has superior strength characteristics. By sliding the component parts into one another (as described above and below) the strength of the fence is vastly increased. This is important for maintaining structural coherence during significant seismic activities and very high winds.

ICC-ES Report

[0019] Applicant recently requested the generation of an International Code Council Evaluation Service (ICC-ES} report for the embodiment shown in FIG. 1.

[0020] For the seismic evaluation, it was concluded that metal fence 10 meets the requirements of ASCE 7-16 Section 15.6.8 for the following assumptions: [0021] The design spectral response acceleration parameter at short periods, SDS1.0. [0022] Risk Category is I or II. [0023] Seismic Design Category A, B, C or D. [0024] The mapped MCER, spectral response acceleration parameter at a period of 1 second, S1<0.6 g.

[0025] For the wind evaluation, it was concluded that metal fence 10 can resist Basic Wind Speed of 95 mph for the following assumptions: [0026] Exposure Category is C. [0027] Risk Category is I or II. [0028] Kzt=1.0 [0029] Gust-effect factor, G=0.85 [0030] Force Coefficient, Cf=1.45

Second Preferred Embodiment

[0031] FIGS. 8 and 9 show another preferred embodiment of the present invention. Metal fence 20 includes posts 11 inserted into concrete footing 12. Metal boards 16 are horizontally slid into rectangular openings 22 (see also FIG. 10).

Third Preferred Embodiment

[0032] FIGS. 11-16 show another preferred embodiment of the present invention. Metal fence 30 includes posts 11 inserted into concrete footing 12. Top rail 13 and bottom rail 14 are slid into rectangular opening 14 of posts 11 (see also FIG. 14). Metal channels 36 are vertically connected between rails 13 and 14 and pushed flush against posts 11. In preferred embodiment metal channels 36 are approximately 1-inch2-inch and are also fabricated from extruded metal and are coated for protection against the elements and rusting. Metal boards 16 are slidingly connected horizontally as shown between the channels formed by channels 36 and rails 13 and 14 (see also FIGS. 15 and 16).

Sound Insulation

[0033] Board 16 tube has a hollow center that is preferably filled with acoustical foam 40 (FIG. 17). The utilization of acoustical foam 40 meets the typical noise reduction standards of most cities and counties. A fence utilizing boards 16 filled with acoustical noise reducing foam, when installed, can be used as a sound absorption or sound block and be installed up to 16 feet in height to effectively reduce noise where necessary.

Fourth Preferred Embodiment

[0034] FIG. 18 shows another preferred embodiment of the present invention. Metal fence 40 includes posts 11 inserted into concrete footing 12. Top rail 13 and bottom rail 14 are slid into rectangular opening 14b of posts 11 (see also FIG. 14). Metal channels 36 are vertically connected between rails 13 and 14 and pushed flush against posts 11. Metal boards 16 are slidingly connected horizontally as shown between the channels formed by channels 36 and rails 13 and 14 (see also FIGS. 15 and 16). inch thick tempered glass 104 is slide between 11 aluminum tracks 103. 11 aluminum tracks 103 are slid into vertical slots cut into posts 11, for stability.

Fifth Preferred Embodiment

[0035] FIG. 19 shows another preferred embodiment of the present invention. Metal fence 50 includes posts 11 inserted into concrete footing 12. Top rail 13 and bottom rail 14 are slid into rectangular opening 14b of posts 11 (see also FIG. 14). Metal channels 36 are vertically connected between rails 13 and 14 and pushed flush against posts 11. Metal boards 16 are slidingly connected vertically as shown between the channels formed by channels 36 and rails 13 and 14 (see also FIGS. 15 and 16). inch thick tempered glass 104 is slide between 11 aluminum tracks 103. 11 aluminum tracks 103 are slid into vertical slots cut into posts 11, for stability.

[0036] Although the above-preferred embodiments have been described with specificity, persons skilled in this art will recognize that many changes to the specific embodiments disclosed above could be made without departing from the spirit of the invention. For example, various types of metals may be utilized for the fence components, including aluminum. Therefore, the attached claims and their legal equivalents should determine the scope of the invention.
