The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appending claims. Various inventive features are described below herein that can each be used independently of one another or in combination with other features. 
     ILLUSTRATIVE EMBODIMENT AND ADVANTAGES OF INVENTION 
       FIG. 1  is a perspective view of a deck  1  a surrounding an exterior space as may be attached to a residential home or apartment of the prior art. The deck  1  of  FIG. 1  is illustrative of those well known to those of ordinary skill in the art constructed with adjacent decking members  3   a  and gaps  3   b  to form decking  3  across joists. A rail cap  8  positioned on rail posts  5  and vertical pickets  6  define the perimeter of the deck  1  creating the deck area  2 . Although not shown, additional horizontal members  7  may be affixed to the outer joists and or the pickets for added strength. As illustrated in  FIGS. 2-10 , it is an object of the invention to disclose a system allowing for enclosure of a deck  1  similar to that disclosed in  FIG. 1  without regard to the deck area  2  or the outline of the perimeter formed by the rail cap  8 . As will be discussed herein, one of ordinary skill will appreciate that the deck curtain system  10  and its method of use will vary from that shown in  FIG. 1  without departure from the spirit and intent of the invention disclosed herein. 
       FIG. 2  is perspective overview of one embodiment of the deck curtain system  10  disclosed enclosing a deck  1  with a set of curtains  60  around an exterior deck area  2 . As shown, the deck curtain system  10  is comprised of a combination of vertical posts  20  attached to the rail cap  8  of the deck  1 , via attachment bases  40 , with horizontal cross bars  30  positioned between the upper portion of the vertical posts  20  upon which the curtains  60  may be hung.  FIG. 2A  is a perspective view of one section of the deck curtain system  10  as implemented to a deck rail cap  8  surrounding a deck  1 . As disclosed, the deck curtain system  10  has an approximate total height of 6-9 feet to provide privacy and/or sun and wind protection as may be desirable to the user of the deck  1 . One of ordinary skill will appreciate that the deck curtain system  10  may be configured with vertical posts  20  having other dimensions and/or additional size or heights as desirable. Accordingly, curtain  60  may have a top  62  and a bottom  63  as shown as well as a entry-sleeve  61  which the cross member  30  may enter to support the curtain  60  when hung between the vertical posts  20 . One of ordinary skill will appreciate that the embodiment of the curtain  60  shown through-out the various FIGS is for illustration only and variations in curtains dimensions, curtain type as well as entry-sleeve configurations herein will be obvious to those of ordinary skill in the arts without departure from the spirit and intent of the invention disclosed herein. 
       FIG. 3  is perspective view of  FIG. 2  with the curtains  60  removed to better illustrate the structural components of the deck curtain support structural components used to surround the exterior deck. 
       FIG. 4  is a detailed view of one illustrative embodiment of a vertical post  20  of the deck curtain system  10  disclosed herein.  FIG. 4A  is a detailed view of the end of the vertical post  20  with the finial  23  removed. As shown in the preceding figures, the vertical post  20  may be configured with an open end  20   a  and base end  20   b . An end cap  21  having an opening, which may be threaded,  22  may be affixed in open end  20   a . A finial  23 , having a threaded post  23   a , and an upper body portion having a size or shape, may be affixed to the upper most portion of the vertical post for ornamental purposes, as shown. Further, as shown in  FIGS. 4 and 4A , the vertical post  20  may configured with adjustable section  24  as a second end positioned in a main section  27 . The vertical post may be configured for height adjustment via holes  25  positioned in the adjustable section  24  and main section  27  with a spring button latch  26  positioned therein. As is well known to one of ordinary skill, depressing spring button latch  26  at hole  25  in a first position allows the adjustable section  24  to slide out or in across the spring button latch  26  and to a new hole at a second or third position. (Not shown) One of ordinary skill will appreciate that the embodiment of the vertical post  20  shown at  FIGS. 4 and 4A  is discussed in detail herein for purposes of enablement and that variations of vertical posts  20  allowing height adjustment not shown herein will be obvious to those of ordinary skill in the arts without departure from the spirit and intent of the invention disclosed herein.
