BACKGROUND OF THE INVENTION
The present invention pertains to hand held devices for protecting a user from the harmful effects of ultraviolet radiation from the sun.
A significant medical problem in the United States and in the world, is the increase of the incidents of skin cancer. The ozone layer surrounding the earth is suppose to block out harmful ultraviolet radiation from the sun. However, it is common knowledge that the ozone layer is becoming thinner each year and in point of fact, there are certain locations around the globe were the ozone layer has completely disappeared. The occurrence of melanoma type cancers had a significant increase having doubled in the past 20 years.
During the course of a year, and especially during the warm summer months, individuals that tend to participate in a number of outdoor activities, which range from athletic type endeavors in which the person participates, participation as a spectator in outdoor events such as baseball games and tennis matches and merely resting in the warm sun, such as on a beach or at a lake.
According to the American Cancer Society and others, people engaging in outdoor activities during the summer months and, for that matter the entire year, are encouraged to cover as much as the unprotected portion of the exposed skin from direct contact with sunlight. One method of accomplishing this is to wear head covering and neck covering, the most vulnerable or exposed portion of the human anatomy, especially during participation of a spectator sport, are the head, face, and back of the neck, assuming normal attire is worn.
It is not always possible to have a hat, which covers the exposed portions of the anatomy that are most vulnerable. Therefore, people have resorted to using a hand held sun shade or sun shield devices to accomplish this task. One such device is a combined fan and sun shade shown in U.S. Pat. No. 946,078 or U.S. Pat. No. 4,911,611.
A number of fan like devices could be used for this same purposes. Illustrative of such fans are U.S. Pat. Nos. 689,648; 2,122,901; and 2,417,194; Re 22,796 as well as Design Patents 202,603; 247,580; 266,385; and 347,726.
BRIEF SUMMARY OF THE INVENTION
A light weight sun shield can be achieved by combining a frame, which is adapted to hold a material which is adapted to reflect or filter out ultraviolet radiation in combination with a handle that can be positioned at an angular relationship either perpendicular to or parallel with the frame. The handle is adapted for positioning at any desired angular relationship to the frame so that the sun shield can be hand held or other wise positioned relative to the body of a user to screen harmful radiation from exposed portions of the users anatomy. Thus, in one aspect, the present invention is a hand held sun shield for protecting a user from the harmful effects of sunlight comprising in combination; a shade portion consisting of a frame having a generally rectangular shape and defining a central open portion, the open portion closed by a material adapted to reflect ultraviolet radiation from sunlight, means on the shade portion to position handle at one of perpendicular, parallel, or both perpendicular and parallel to the central open portion of the frame the means further adapted to permit a user to position the handle at an angular relationship to the frame when parallel to or perpendicular to the frame, and a removable handle for attachment to the means on the shade portion of the sun shield.
In another aspect the sun shield according to the present invention utilizes threaded studs and balls or threaded apertures and a threaded portion of the handle to attach the handle to the sun shade.
In another aspect, the present invention permits attachment means of the handle to the sun shade to be positioned around the periphery of the frame portion at different locations to effect optimum positioning of the frame for protection of the user.
