     BACKGROUND OF THE INVENTION 
     The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art. 
     1. Field of the Invention 
     The present invention relates generally to the field of fencing and more specifically relates to an adjustable sectional privacy fence system for modular use. 
     2. Description of the Related Art 
     Modernly many people live in houses on property. “Good fences make good neighbors,” observed the poet Robert Frost; and although he was speaking of the New Hampshire stone walls that separated his land from that of his neighbor, the fact is that since his time, America has become a nation of fences with good neighbors. In cities and suburbs across the country, fences often define our household boundaries, and fences separate us, our pets and our properties, one from another. 
     Fences establish a perimeter to our properties, enclosing what we own and value within a solid barrier, blocking entry to those who might covet our possessions or threaten us with harm. Fences provide a ‘visual curtain’ as well, ensuring that even in a densely populated urban or suburban setting, we can enjoy a measure of personal or familial seclusion on our own parcel of earth. There is no doubt that a privacy fence is a great means of keeping your neighbor from minding your business and protecting your property. The trouble with a privacy fence is that view may be compromised for the occupants who from time to time might prefer to adjust, and enjoy a longer view that may be realized from a lower fence. A fence system that allows for adjustability is desirable. 
     Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 5,661,946 to Kenneth Davis; U.S. Pat. No. 5,577,710 to George T. Kirby; and U.S. Pat. No. 6,772,998 to Ronald William Bebendorf. This art is representative of fences. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed. 
     Ideally, an adjustable sectional privacy fence system should provide privacy when desired and efficiency in use and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable adjustable sectional privacy fence system to avoid the above-mentioned problems.

     DETAILED DESCRIPTION 
     As discussed above, embodiments of the present invention relate to a fencing product and more particularly to an adjustable sectional privacy fence system as used to improve the efficiency and effectiveness of fences. 
     Generally speaking, the adjustable sectional privacy fence system as disclosed herein is used to improve the adjustability of fencing via modular means. The adjustable fence may be a vinyl or vinyl-clad sectional privacy fence, preferably fabricated and sold in 6-foot, ready-to-install sections, featuring a unique, retractably elevating design which permits the fence height to be altered easily and repeatedly. The adjustable fence, in superficial appearance, may closely resemble other high-quality vinyl or vinyl-clad galvanized privacy fencing, with squared posts, pyramidal post-caps, and intermediate sections of continuous, vertically oriented slat-style panels. Like other privacy fencing, the adjustable fence may be produced in several alternative designs with round posts and scalloped panels, or a woven-rail appearance, for example. As noted, the adjustable fence may be produced in modular, 6-foot sections comprising either of a mid-post and two panels, or a single panel and two end-posts. The sections may molded and pre-fitted to join and lock together, and virtually any property line or slope profile may be accommodated. 
     Unlike other vinyl or vinyl-clad privacy fencing, the adjustable fence design permits the height of the fence to be varied. This is accomplished by an extendable, retractable design in which the standard 6-foot fence-posts and panels conceal within their interior another, slightly thinner set of posts and panels that may be raised on a sliding track-and-channel mechanism to extend upward, adding height to the fixed fence and appearing continuous with it. The system might for example employ a pin-and-hole, variable-height locking system that may be operated manually, section-by-section, by the homeowner; or a motorized, chain-and-sprocket system, electrically powered and operated by a wired or wireless switch or remote-control, that may raise and lower multiple sections of the fence simultaneously. In either case, the extending sections of the Adjustable Fence may be continuous with the fixed sections, and the slot through which the interior posts and panels rise may be sealed with a flexible, two-sided rubber gasket. Various adjusting means may be used. 
     The adjustable fence may be raised and extended from a fixed height of 6 feet to a maximum height of 8 to 10 feet, thus offering the homeowner a significant choice in the level of privacy, or the expansiveness of view, afforded by the fence. This adaptability may be ideal for those who, for example, wish to enjoy a more expansive view of their surroundings during the day, yet desire a high level of visual privacy at night. The adjustable fence may be ideal for households with swimming pools or spas; and the height-adjustable design might also appeal strongly to a variety of commercial and institutional enterprises and establishments. 
     Referring now to the drawings more specifically by numerals of reference there is shown in  FIGS. 1-5 , various views of adjustable sectional privacy fence system  100  comprising: a plurality of adjustable sectional privacy fence assemblies  110 ; each of adjustable sectional privacy fence assemblies  110  comprising at least one post  120 , at least one post-cap  130 , and at least one panel-section  140  (may be telescopically related as shown), powerer  150 , and (version of) mechanical adjusting assembly  160 ; wherein adjustable sectional privacy fence system  100  comprises the plurality of adjustable sectional privacy fence assemblies  110  (in adjacent communication and connection as a modular coupled apparatus/system), powerer  150 , and mechanical adjusting assembly  160  in functional combination.

Summary:
A privacy fence includes a lower base portion and a telescopically extendable upper portion that is vertically movable relative to the lower base portion to provide a privacy fence that has a selectively adjustable height. The lower base portion is formed of a panel section extending between two spaced apart posts. The upper telescopic portion also includes a panel member extending between two post members wherein the panel member is received within the interior of the base panel portion and the two post members are received within the posts and connected to an actuation mechanism. As desired, the actuation mechanism can be operated to move the post members vertically, which in turn raises the panel member telescopically out of the base panel portion. Optional flower pots can be mounted on top of the post members to be movable therewith, or to provide flower pots on conventional fence posts.
