     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 shows the simplest and basic idea of the invention. The protection of a person&#39;s face in the course of sunbathing, by a shield 2 against sunburning, while the weight of a person&#39;s head is resting on the base 1 to secure the invention by way of example, on the sand at a beach or on the lawn in a park, in the necessary position. A supporting rod 3, is equipped with two hinge-like clamp-joints 4 and 5 at each end. The base 1 and the shield 2 have been mounted onto the frames 8 and 9 which in turn represent part of the clamp-joints 4 and 5 as described in FIGS. 4 and 7. Clamp-joint 4 provides herewith orbital adjustment to any desired position. More complete adjustment and function will be described with FIG. 6. 
     The base and shield may be of different materials, preferably plastic or cardboard. They may be of different sizes, shapes and colors, depending on the consumer&#39;s request. The frames may be of different materials, preferably non-rusting or non-corroding metal rods. They may be of different sizes or shapes depending on the design of the bases and shields. The rod may be of different materials, preferably non-rusting or non-corroding metal rods. 
     FIG. 2 shows the invention by way of example being attached to the backrest 10 of a lounge or lawnchair, by means of tying the clamp-joint 4 with a ribbon 11 to the upper part of said backrest. 
     Base 1 and shield 2, have been provided each with a pocket-like sheath 7, which serves to shove the base 1 and shield 2 onto the frames 8 and 9. The sheaths are sized to fit snugly over said frames, with enough friction to keep them from falling off. 
     Further, FIG. 2 shows that the base 1 and shield 2 are of the same principal design, also recognizable from FIGS. 1, 4, 5 and 6, and may be used for the same purpose. Which means, base 1 may serve as a shield 2, while shield 2 may serve as a base, or vice versa. 
     Therefore, to simplify the remaining descriptions and claims, the base will be called &#34;shield&#34; unless otherwise specified. However, the shield may be of different sizes, in particular the outside dimensions. They may be of different materials, different shapes, colors, etc. Furthermore, both surfaces of each shield may be plain or contain eye attracting matters, like advertisings, slogans, pictures, decals, names of persons, messages, and in particular on beaches or other public places, communicating writings or fun patches, like for instance, &#34;Girl Wanted&#34;, &#34;Let&#39;s Boogie&#34;, or even a phone number, etc. For example, &#34;Keep Out&#34; 6 in FIG. 1. 
     All of this may be either imprinted, painted, or attached. Both surfaces of each shield may be used as above because the inside dimensions of the sheath 7 are symmetrical to the shield&#39;s outside dimensions. This makes it possible to pull the shield off the frame 8 or 9, or exchange it for another one, dispose of it, store it, or reverse it and shove it back onto the frame within seconds. 
     FIG. 3 shows the invention in a folded position. The folding can be accomplished by releasing the locking action of the clamp-joints 4 and 5 and swinging the frames 8 and 9 including the shields 1 and 2 around the axis of said clamp-joints toward the rod 3, until they come to rest alongside said rod 3. Thereafter, the clamp-joints 4 and 5 may remain locked to keep the shields in that folded position. If for any reason the shields 1 and 2 shall be removed from the frames 8 and 9, for instance for shipping by manufacturers, safer storage or disposal by consumers, the folded remaining assembly will be even lighter and more compact. 
     FIG. 4 shows a portion of shield 2 with its sheath 7 and a portion of the frame 8. Both ends of said frame have been formed to hooks 16, for the purpose of anchoring inside the cylindrical pivot 15, which consists of a material with good frictional characteristics, like plastic or aluminum. 
     FIG. 7 shows part of the shield 2, part of the frame 8, anchored in pivot 15, and the upper portion 14, of rod 3, which is formed strap-like around the pivot 15 and extending downwards to a suitable length 19. The length 19 and the rod 3 have been connected by means of a carriage-bolt 17, a wing-nut 18 and a washer 20. It will be noted that the direction of turn of the rod 3 around pivot 15 is such that the down-bearing weight of shield 2 due to gravity causes a tightening of the joint 5. This assembly represents the clamp-joint 5. The clamp-joint 4 at the other end of rod 3, is of the same design and in symmetrical position. The design and the frictional gripping function of this assembly is well known, except the way of anchoring the hooks 16 inside the pivots 15. 
     Each clamp-joint 4 and 5 has an angular adjustability of over 300°, which makes it possible to place shield 1 in opposite direction to shield 2, as shown necessary in FIG. 8. Any suitable object heavy enough, for instance a rock 22, may be placed on top of shield 1 to secure the invention in its adjusted position. Referring back to FIG. 1, the same method can be used, if for any reason a person prefers, not to rest the head on shield 1. 
     FIG. 6 demonstrates the possibility to adjust shield 2, to any angle of incidence of the sunrays. The line H - B represents the directional position of a person, using the invention. Shield 1 lying flat on the ground can be rotated 360°around its center K, in either direction C or F. For example FIG. 6 shows shield 1 has been rotated in direction C in relation to line H - B, whereby rod 3 has been positioned on a common line between the sun D and the center K of shield 1. 
     By means of the pivotable clamp-joints 4 and 5, the flat surface of shield 2 can now be adjusted perpendicular to any angular incidence of the sunrays. 
     In the drawings and specification there have been disclosed preferred forms of the invention, and although specific terms are employed these are used in a generic sense and not for purposes of limitation, the scope of invention being defined in the following claims.
