BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a fence panel assembly and fence that do not permit a line of vision from one side of the panels between the panels to the other side of the panels while still providing ventilation channels between the panels for resistance to high wind. 
     2. Description of the Prior Art 
     A variety of fence devices have been used to provide the fence owner with protection and privacy. Prior art fence devices have consisted of fence posts, vertical panels, and horizontal mounting members. 
     Prior art fences are typically assembled with mechanical fasteners such as bolts, nuts, screws, nails or slipnotch fasteners. The use of multiple mechanical attachments, such as those disclosed in U.S. Pat. Nos. 4,324,388; 3,993,289; 4,471,947; 4,809,955; and 4,202,532, results in time consuming assembly. 
     Prior art fences typically are open fences such as those disclosed in U.S. Pat. Nos. 4,202,532; 4,809,955; 4,324,388; and 3,993,289. These fences do not provide privacy to the fence owner. The spaces that exist between conventional fence panels often increase in size over time as a result of warping, aging, shrinking, or rotting of the panels. Prolonged exposure of the fence panels to adverse environmental conditions such as sunlight, rain, and wind can weaken the structural integrity of the fence. A closed fence design, such as that disclosed in U.S. Pat. No. 4,471,947, does not provide ventilation for wind or rain forces. Such a design is more likely to be blown over in a high wind than a fence with spaces between panels. 
     Many prior art fence panels are composed of wood, metal, or plastic resins. These materials require periodic maintenance and are difficult to assemble. 
     Prior art fence devices fail to solve the problem of providing privacy by not permitting a line of vision between the fence panels and providing resistance to high winds by providing ventilation channels between the fence panels. 
     The present invention overcomes the problems of the prior art by requiring minimal use of mechanical fasteners and easy assembly of the fence, and providing ventilation channels between fence panels while not permitting a line of vision between adjacent panels. The present invention is uniquely designed to allow the fence panels to successively slide onto two horizontal stringers. The fence panel edges are designed to overlap the edges of adjoining fence panel to form a closed fence with ventilation air channels. This provides the fence owner with privacy and a weather resistant fence. The fence panels and stringers of the present invention are made of a vinyl material. This material is light and requires little to no maintenance. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a fence panel assembly and a fence that do not permit a line of vision through the fence or the fence panel assembly. The fence panels are uniquely designed to form angulated ventilation channels that resist rain and wind abuse. 
     Fence posts are driven into the ground to provide a mounting assembly for the placement of the stringers. The required number and height of the fence posts will vary with the individual fence owner&#39;s needs. Two substantially parallel horizontal mounting members, such as stringers, are secured in a substantially horizontal orientation to the fence posts by mechanical fasteners such as bolts and nuts. The stringers run the full length of the fence and comprise upper and lower lobed wings that engage the fence panels. 
     The fence panels are arranged in a substantially perpendicular orientation to the stringers. A plurality of fence panels, each with upper and lower mounting channels, slidably engage the lobed wings of the two stringers. Each panel comprises a front channel border and a rear channel border extending outwardly from opposite sides of the central body region of the panel. At least one spacer member slidably engages the rear channel border in a substantially perpendicular configuration to each fence panel. The spacer member is attached to ensure maintenance of a uniform distance between the adjacent fence panels and may be of various sizes to accommodate the desired distance between panels. The overlap of these borders forms angulated channels for ventilation. As used herein, the term &#34;angulated channel&#34; means a channel comprising a bend or an angle of sufficient magnitude such that an air current entering one end of the channel must change direction in order to exit the other end of the channel, as shown in FIG. 3. Line of sight vision from one side of the fence, between the panels, to the other side is not permitted by the overlap of the front channel border with the rear channel border of adjoining fence panels. 
     The angulated channels permit a flow of air between the two adjacent fence panels, which enhances the structural integrity of the fence during adverse environmental conditions such as rain and high winds. 
     Arch panel members connect the fence panel assemblies at substantially right angles. The use of the arch panel members permits a combination of four fence panel assemblies to enclose a substantially rectangular area. Two extension arms extend outward from the arch panel member. The extension arms are attached to fence panels located at one end of each fence panel assembly. The stringers are secured to fence posts by mechanical fasteners. 
     The fence panels and fence posts may be equipped with a plurality of caps. The cap slidably fits over the top of the panel or post. 
     The fence posts may be of a galvanized metal and the stringers, fence panels, arch panel members, spacer and caps may be made of a vinyl material. The fence and fence panel assembly design of the present invention may be easily assembled.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in FIGS. 1 and 2, the fence embodiment of the present invention comprises two stringers 1 in a substantially parallel arrangement, each of said stringers comprising a mounting assembly 7 capable of securing the stringer to a fence post 5. The fence embodiment further comprises a plurality of fence panels 3 slidably mounted on the stringers in a substantially parallel arrangement. Each of the fence panels is mounted in a substantially perpendicular configuration to the stringers. The fence panels further comprise angulated channels 25 capable of permitting air flow between the fence panels such that the fence panels are capable of being spaced apart with respect to each other so as not to permit a line of vision from one side of the fence panels between the fence panels to the other side of the fence panels while permitting air flow through the angulated channels, as shown in FIGS. 3 and 4. 
     In a preferred embodiment, the stringers comprise an upper lobed wing 9 and a lower lobed wing 11. The fence panels comprise an upper mounting channel 13 and a lower mounting channel 14, capable of slidably engaging the upper lobed wing and lower lobed wing, respectively, of the stringers. The upper lobed wing and lower lobed wing of the stringer extend substantially the length of the stringer.
