fig1 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 fig4 and 7 . clamp - joint 4 provides herewith orbital adjustment to any desired position . more complete adjustment and function will be described with fig6 . 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 . fig2 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 , fig2 shows that the base 1 and shield 2 are of the same principal design , also recognizable from fig1 , 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 fig1 . 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 . fig3 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 . fig4 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 . fig7 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 fig8 . 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 fig1 the same method can be used , if for any reason a person prefers , not to rest the head on shield 1 . fig6 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 fig6 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 .
this invention presents a foldable and portable shielding device , which serves to protect the head , in particular the face , of a person against sunburning while sunbathing . also , to protect small animals , sensitive flowers , objects like cameras , etc ., from direct sunlight . at the same time the surface of the shielding elements may contain eye attracting matters , like names , slogans , pictures , decals , advertisements , etc .
