The upper edge 28 of the visor 22 may be roughly arcuate in shape or more preferably it may be shaped to provide three angularly positioned, relatively straight edges, a central straight portion above the nose-spanning portion 26 and two angularly positioned straight portions, one adjacent each edge of the visor. The upper edge 28 of the visor 22 is also provided with a pair of locking tabs or extensions 30, 32 which are adapted to be inserted in slits 34, 36
in element [0, as shown for example most clearly in Fig. 4. The slits 34, 36 are preferably so spaced that the visor 22 may lie flush against the element l0 when the latter is in flat, uncurved position, as shown in Fig. 4, and under these circumstances the visor 22 will extend rearwardly and toward the edge ii of the element It). The slits 34, 36 and the locking tabs 30, 32, which are adapted for insertion therein, are preferably angularly positioned with respect to one another so that as the element It] is curved to conform to the shape of a wearers head and the visor is swung into lowered or depending position, the tension on the visor 22 maintains it out of contact with the element I0 and in the depending position shown most clearly in Figs. 1 and 5, in which position the visor conforms approximately to the curvature of the wearers face. In this position the short straight portions of the upper edge 28 of the visor 22, which are adjacent the locking tabs 30, 32, remain in contact with the under surface of the peak l2 whereas the straight central portion of the upper edge 28 of the visor 22 is spaced from the under portion of the curved peak I2 and thus provides a ventilating aperture or gap, as shown for example in Fig. 5.
If the curvature of the depending glare-eliminating visor 22 is to approximate the curvature of the face of a wearer of the sunshield, and this is a preferred condition, the slits 34, 36 and the tabs 30, 32 should be angularly positioned so that the angle between each slit and a line joining the centers thereof and the angle between each tab and a line joining the centers thereof is between 25 and 30".v
If desired, a supplemental pair of slits 38, 40 may be provided so that the glare-eliminating shield may be positioned at a different distance from the wearers face, and if these slits are positioned at different angles to each other than are the slits 34, 36, the curvature of the glareeliminating visor may be altered by insertion of its locking tabs in the supplemental pair of slits.
When the sunshield is not in use the glareeliminating visor may be swung upwardly to the position shown in Fig. 4, in which case it will lie flush with element Ill and thus permit stacking of the sunshields for easy handling and shipment, even though the resilient element l8 remains in place and causes the element 10 to take the curved position shown in Fig. 1.
Since certain changes may be made in the above article of manufacture without departing from the scope of the invention herein involved,
it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
What is claimed is:
1. A sunshield comprising, in combination, a body member comprising a peak portion and integral, rearwardly extending temple shields, shaped to provide a head-engaging edge, a resilient wire-like head-gripping member detachably aflixed to the head-engaging edge of said body member for causing predetermined curvature of said peak portion and displacement of said temple shields towards one another and into head-gripping position, a transparent visor having selective light-transmitting properties,
and means afiixing said visor to said body memher to depend therefrom in face-conforming curvature before the eyes of a wearer of said sunshield with its upper edge spaced rom said headgripping member and with its lower edge substantially in engagement with the wearers face, when said sunshield is in position on a wearers head and to lie closely thereadjacent with its lower, face-engaging edge positioned rearwardly and adjacent the head-engaging edge of said peak portion when said head-gripping member is removed.
2. The sunshield defined in claim 1 wherein said visor is afiixed to said body member by a pair of spaced locking tabs extending from the upper edge of said visor and engaging angularly positioned slits provided in said body member.
3. The sunshield defined in claim 2 wherein said slits make with each other an angle of the order of 125.
