DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) Referring to FIG. 1, a diagram of a section of a fence 100 is shown illustrating application of a hidden clip in accordance with an embodiment of the invention. In various instances, the fence 100 comprises a number of fence posts 102 and a number of panels 104. The panel 104 comprises a number of fence rails (or simply rails) 106. In one example, the panel 104 may also comprise a number of pickets 108 attached to the rails 106. In another example, a solid panel (not shown) may be attached to the rails 106.

(12) Each end of the rails 106 protrudes into one of the fence posts 102 and is held in place by a clip 110. The clips 110 are hidden from view within the rails and posts. The panel 104 is assembled to and disassembled from the posts 102 by compressing the clips 110 to slide the respective rail end into and out of the respective post 102.

(13) Installers may set the posts 102 in cement (or concrete) using conventional techniques. The cement is allowed to harden before inserting the panels 104. Because the panels 104 are generally not assembled right away to the posts 102, there is far less chance the posts 102 will be disturbed before the cement has had a chance to harden. In addition, the clips 110 eliminate having to screw the panels 104 to the posts 102. Shorter posts may be used (even in the frost-belt) and installation time is significantly reduced, all of which reduces the cost of the fence.

(14) Using the clip 110 in accordance with an embodiment of the invention, there is no need to notch the ends of the rails 106. Installers can simply make a straight cut and, with the same saw (e.g., a hack saw), score the top of the rail 106 to form a slot, insert the clip 110 into the rail 106, and insert the end of the rail 106 into an opening in the side of the post 102. The process in accordance with an embodiment of the invention reduces costs and time on the job.

(15) The panels 104 are removable without tools. If a panel 104 is damaged, repairs can be performed without removing the posts 102. This substantially reduces repair costs for the consumer. In addition, the consumer can easily remove any panel 104 installed with the clips 110 to create an instant gate. Another benefit of the present invention is that the clips 110 block insects (e.g., bees, wasps, hornets, etc.) from gaining entry into cavities within the post 102 by filling the void between the rail 106 and the punched/routed hole in the post 102.

(16) The posts 102 no longer need screws to hold the rails 106 in place. The posts 102 can be prepared for assembly with the rails 106 in a single step of inserting the posts 102 in a machine once to punch/route the rail hole. This significantly reduces manufacturing time and, therefore, reduces manufacturing costs.

(17) Referring to FIG. 2, a cutaway view is shown illustrating the hidden clip 110 coupling the fence post 102 and the fence rail 106 of FIG. 1. A tab 112 of the clip 110 extends above a body of the clip 110 and engages a slot in the top of the rail 106. The tab 112 generally holds the clip 110 in position in the rail 106. In an uncompressed state, a tang 114 of the clip 110 extends below the body of the clip 110 and through the bottom of the rail 106. The tang 114 of the clip 110 is configured to engage an interior surface of the post 102, thus preventing the rail 106 from being removed from the post 102 while the clip is uncompressed. When the clip 110 is compressed, the tang 114 rises up into the rail 106 (e.g., illustrated by a dashed line) allowing the rail 106 to be removed easily from the post 102.

(18) Referring to FIG. 3, a diagram is shown illustrating details of an illustrative embodiment of the clip 110 of FIGS. 1 and 2. In various embodiments, the clip 110 may be formed from a strip of metallic material (e.g., steel, aluminum, copper, nickel, tin, an alloy thereof, etc.). In some embodiments, the clip 110 may be formed from a non-metallic material (e.g., plastic, re-enforced Nylon, polyvinyl chloride (PVC), high-density polyethylene (HDPE), etc.). However, other materials with similar properties may be used to form the clip 110. In embodiments utilizing metallic materials, the metallic material may be treated to prevent oxidation or corrosion (e.g., zinc coated, oxide coated, anodized, stainless steel, etc.).

(19) In one example, the clip 110 may be formed from a strip of material having a first portion 120, a second portion 122, and a third portion 124. The first portion 120 may be bent to form a body of the clip 110. The body of the clip 110 compresses when pressure is applied and returns to an uncompressed state when pressure is removed. The second portion 122 may be bent to form the tab 112 on the top of the clip 110. The third portion 124 may be bent to form the tang 114 on the bottom of the clip 110. Various dimensions (e.g., A, . . . , R) of the clip 110 are illustrated if FIG. 3. In one example, the clip 110 may be implemented with the following dimensions:

(20) A=about 6 inches;

(21) B=about 1 inch;

(22) C=about 0.375 of an inch;

(23) D=about 0.675 of an inch;

(24) E=about 0.675 of an inch;

(25) F=about 0.675 of an inch;

(26) L=about 0.375 of an inch;

(27) M=about 2.63 inches;

(28) N=about 2.88 inches;

(29) O=about 0.45 of an inch;

(30) P=about 0.25 of an inch;

(31) Q=about 0.125 of an inch;

(32) R=about 0.5 of an inch.

(33) However, one or more dimensions may be varied to meet the design criteria of a particular implementation. In one instance, dimensions L, M, O, and R may be varied as follows:

(34) L=about 0.21 inches;

(35) M=about 2.84 inches;

(36) O=about 0.458 of an inch;

(37) R=about 0.375 of an inch.

(38) In various embodiments, the tang 114 may form an angle of approximately 24 degrees with the bottom of the clip 110.

(39) Referring to FIG. 4, a diagram is shown illustrating an end view, a side view, and a top view of an illustrative embodiment of the fence rail 106 of FIG. 1. In one example, the fence rail 106 comprises a number of internal ribs 130. In one example, the rail 106 may be implemented as an aluminum extrusion. The clip 110 is generally configured to engage the ribs 130 (e.g., illustrated below in connection with FIG. 5). A slot 132 is disposed near the end of the rail 106. In various embodiments, the slot 132 is punched or cut into a top surface of the rail 106. When the clip 110 is inserted into the rail 106, the tab 112 on the top of the clip 110 protrudes into the slot 132, locking the clip 110 into position in the end of the rail 106. The tang 114 on the bottom of the clip 110 (shown in FIG. 2) protrudes through the opening (void) in the bottom of the rail 106 to engage the inner surface of the post 102 when the rail 106 is inserted into the post 102.

(40) Referring to FIG. 5, a diagram is shown illustrating the clip 110 in accordance with an embodiment of the invention blocking off an end of the fence rail 106. By blocking off the opening in the end of the rail 106, the clip 110 prevents access by insects (e.g., bees, wasps, hornets, etc.) to an internal cavity of the fence posts 102. The dimensions of the rail 106 and the clip 110 are configured such that the small exposed spaces between the rail 106 and the clip 110 do not afford the insects access to the inside of the post 102 or the shelter needed for building hives (nests).

(41) Referring to FIG. 6, a perspective view of an illustrative embodiment of a fence post 102 is shown. The fence posts 102 have openings 140 into which the rails 106 are inserted. The openings 140 are configured generally to allow the rails 106 to be swung out of alignment with a plane of the fence, facilitating easy removal of the panels 104 (described below in connection with FIG. 9). The dimensions of the openings 140 are configured such that the small exposed spaces between the rails 106 and edges of the openings 140 do not afford the insects access to the inside of the post 102 or the shelter needed for building hives (nests).

(42) Referring to FIG. 7, a diagram of a clip 200 is shown illustrating details of another illustrative embodiment in accordance with the invention. The clip 200 may be used in place of the clip 110 shown in FIGS. 1 and 2. In various embodiments, the clip 200 may be formed from a strip of metallic material (e.g., steel, aluminum, copper, nickel, tin, an alloy thereof, etc.). In some embodiments, the clip 200 may be formed from a non-metallic material (e.g., plastic, re-enforced Nylon, polyvinyl chloride (PVC), high-density polyethylene (HDPE), etc.). However, other materials with similar properties may be used to form the clip. In embodiments utilizing metallic materials, the metallic material may be treated to prevent oxidation or corrosion (e.g., zinc coated, oxide coated, anodized, stainless steel, etc.).

(43) In one example, the clip 200 may be formed from a strip of material have a first portion 202, a second portion 204, and a third portion 206. The first portion 202 may be bent to form a body of the clip 200. The body of the clip 200 compresses when pressure is applied and returns to an uncompressed state when pressure is removed. The second portion 204 may be bent to form a tab similar to the tab 112 on the top of the clip 110. The third portion 206 may be bent to form a tang similar to the tang 114 on the bottom of the clip 110. Exemplary dimensions (e.g., A, . . . , R) of the clip 200 are illustrated if FIG. 7. In one example, the clip 200 may be implemented with the following dimensions:

(44) A=about 4.19 inches;

(45) B=about 0.975 inch;

(46) C=about 0.370 of an inch;

(47) D=about 0.615 of an inch;

(48) E=about 0.615 of an inch;

(49) F=about 0.615 of an inch;

(50) L=about 0.370 of an inch;

(51) N=about 1.95 inches;

(52) O=about 0.450 of an inch;

(53) P=about 0.315 of an inch;

(54) Q=about 0.167 of an inch;

(55) R=about 0.255 of an inch.

(56) However, other dimensions may be implemented to meet the design criteria of a particular implementation. In one instance, the tang may form an angle of approximately 24 degrees with the bottom of the clip 200. In contrast to the clip 110, the tab of the clip 200 formed by the second portion 204 and the bend of tang of the clip 200 formed by the third portion 206 are equally distanced from an apex of a radius R in the body of the clip 200.

(57) Referring to FIG. 8, a diagram a fence rail 106 is shown illustrating an end view, a side view, and a top view of another illustrative embodiment in accordance with the invention. In one example, the fence rail 106 comprises a number of lower internal ribs 130 similar to the rail 106. However, instead of having upper internal ribs 130, a top contour 150 of the fence rail 106 is configured to engage the clip 110 when the clip 110 is inserted. In various embodiments, the rail 106 may be implemented as an aluminum extrusion. However, other materials may be used to implement the fence rail 106. The clip 110 is generally configured to engage the ribs 130 and an upper contour 150. A slot 132 is disposed near the end of the rail 106. In one example, the slot 132 may punched into a top surface of the rail 106. In another example, the slot 132 may be formed by cutting (or scoring) the top contour 150 (e.g., using a hacksaw) during construction (or customization) of a section of a fence. The tab 112 on the top of the clip 110 protrudes into the slot 132, locking the clip 110 into position in the end of the rail 106. The tang 114 on the bottom of the clip 110 (illustrated in FIG. 2) protrudes through the opening (void) in the bottom of the rail 106 to engage the post 102 when the rail 106 is inserted in the post 102.

(58) Referring to FIG. 9, diagrams 200a-200d are shown illustrating an assembly/disassembly process for a fence constructed in accordance with an embodiment of the invention. The rails 106 are shown without attached panels for clarity. During an initial stage of assembly, first and second posts 102 are set in cement with a desired spacing and the cement is allowed to harden. As illustrated in diagram 200a, a rail 106 is cut to a length determined by the spacing of the posts 102, slots are punched/cut into a top surface near each end of the rail 106, and a clip 110 is inserted into each end of the rail 106. As illustrated in diagram 200b, a first end of the rail 106 is inserted into an opening in a side surface of the first post 102. As illustrated by diagram 200c, a second end of the rail 106 is aligned with an opening in a side surface of the second post 102. Then, as illustrated in diagram 200d, the rail 106 is slid until the second end of the rail 106 passes through the opening in the side surface of the second post 102 and the clip 110 engages an internal surface of the second post 102. Once assembled, the section of fence may be disassembled by compressing each of the clips 110 while reversing the actions illustrated in the diagrams 200a-200d.
