Description of the Preferred Embodiment
As shown in FIG. 1, a chain link fence assembly 10 is provided. Assembly 10 includes chain link wire fencing 12, a bottom channel or bottom member 14, and a top channel or top member 16. Assembly 10 has a plurality of slats or privacy strips 18, 20, 22, which have respective lock tabs 24, 26, 28, that lock into bottom channel 14.
Wire fencing 12 has a plurality of strands 30, 32, 34, 36, 38. Adjacent pairs of strands 30,32 and 34,36 have bottom connections or barbs 40,42 and have respective top connections 44,46.
As shown in FIGS. 2 and 5, bottom channel 14 has a web 48, a far flange 50 and a near flange 52. Web 48 has a plurality of cutouts 54, 56, 58 which receive respective tabs 24, 26, 28. (See FIG. 1).
As shown in FIG. 5, cutout 54, which is identical to cutouts 56,58, has an inside width 60 and an inside dimension 62, normal to width 60.
As shown in FIGS. 2, 3 and 4, slat 18, which is identical to slats 20,22, has a tubular portion 64, a left fin portion 66 and a right fin portion 68. Tubular portion 64 has an outside width 70 and an outside thickness 71.
As shown in FIG. 4, lock tab 24, which is identical to lock tabs 26,28 has an outer width 72, which is equal to width 70, and has an outer thickness 74, which is equal to thickness 71. Lock tab 24 has a left recess 76 and a right recess 78. Recesses 76 and 78 have an outer width 80 disposed therebetween. Recess width 80 is slightly less than cutout width 60. Thickness 74 of lock tab 24 is slightly less than cutout dimension 62.
Lock tab 24 has a left projecting portion 82 and has a right projecting portion 84. Portions 82,84 are flexible and deformable portions in order that tab portion 24 can be inserted into recess 54. Portions 82,84 lock tab portion 24 into bottom channel 14.
As shown in FIG. 7, top channel 16 has a web 86, a far flange 88 and a near flange 90. Flanges 88,90 have an inner dimension 92 therebetween. Dimension 92 is slightly larger than tubular portion thickness 71.
Fencing 12 is preferably composed of a metal material. Slats 18, 20, 22 are preferably composed of a plastic material. Bottom channel 14 and top channel 16 are preferably composed of a plastic, or metal material.
Channel 14 and 16 are structural members. Bottom channel 14 helps to support slats 18, 20, 22. Slats 18, 20, 22 receive some friction forces from wires 30, 32, 34, 36, 38, if slats 18, 20, 22 are bowed or are subject of a wind load. Such friction forces help to support slats 18, 20, 22 on the wires. Channels 14, 16 take a transverse bending moment when a wind load is applied to slats 18, 20, 22 and wires 30, 32, 34, 36, 38. When the channels 14,16 are suitable designed, the transverse loads from the wind force can be transmitted by the channels 14,16 to the fence posts (not shown), as desired.
Projecting portions 82,84 are arcuate pieces. Lock tab 24 is an extension of tubular portion 64. Lock tab 24 has a near wall portion 83 and a far wall portion 85. The two arcuate projecting portions 82,84 can be cut in order to form four separate projections, if desired.
A second embodiment of part of assembly 10a is shown in FIG. 8. Parts of assembly 10a, which are the same as corresponding parts of assembly 10, have the same numerals, but with a subscript "a" added thereto. Assembly 10a has a bottom channel 94, which has a web 96, a far flange 98 and a near flange 100. Flanges 88,90 face downwardly. Channel 94 has a cutout (not shown) which receives lock tab 24a.
A third embodiment of assembly 10b is shown in FIG. 9. Parts of assembly 10b which are the same as corresponding parts of assembly 10, have the same numerals, but with a subscript "b" added thereto. Assembly 10b has a fencing 12b, a bottom channel 104, a top channel 16b and a median channel 106. Median channel 106 is located at a distance 108 from bottom channel 104 and is located at an equal distance 110 from top channel 16b. Assembly 10b has a plurality of slats 112, 114, 116 which have respective lock tabs 118, 120, 122.
Fencing 12b has wire strands 32b, 34b, 36b, 38b, which have bottom connections 40b, 42b. Bottom channel 104 has a bottom web 124 and a far flange 126 and a near flange 128. Web 124 has cutouts 130, 132, 134. Slat 116, Which is a typical slat, has a tubular portion 136, a left fin 138 and a right fin 140. Each slat 112, 114, 116 is disposed at an angle 142, which is about 45 degrees. Cutout 132 has an inner width, which measures about 1.41 times the size of the width of the tubular portion 136 as measured along a line that is normal to its fin edge.
Lock tab 122 has a left recess 144, a right recess 146, a left projecting portion 148, and a right projecting portion 150. Median channel 106 has a web 152, which has cutouts 154, 156, 158 and has a far flange (not shown) and a near flange 160.
The process of constructing assembly 10 is indicated hereafter.
A. Chain fencing 12 is stretched and connected to suitable fence posts (not shown).
B. Bottom channel 14 is inserted horizontally between the wires 30, 32, 34, 36, 38 just above the bottom connections 40, 42.
C. Slats 18, 20, 22 are inserted vertically in the spaces between respective wires 32, 34, 36.
D. Lock tabs 24, 26, 28 are inserted vertically into respective cutouts 54, 56, 58. Lock tabs 24, 26, 28 are then held in place by their respective projecting portions, such as portions 82,84 of lock tab 24.
E. Top channel 16 is then inserted horizontally in the spaces between wires 30, 32, 34, 36, 38 adjacent to top connections 44,46. Top channel 16 is supported on the top ends of slats 18, 20, 22, which are supported on bottom channel 14.
The process of constructing assembly 10b is the same as the process of constructing assembly 10, except that slats 112, 114, 116 are inserted diagonally in the spaces between respective wires 30b, 32b, 34b, 36b, 38b and except that median channel 106 is inserted just after the bottom channel 104 is inserted and before the slats 112, 114, 116 are inserted through the wires and the median channel 106.
While the invention has been described in its preferred embodiment, it is to be understood that the words which have been used are words of description rather than limitation and that changes may be made within the purview of the appended claims without departing from the true scope and spirit of the invention in its broader aspects.
