Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to head coverings and more particularly, to a collapsible head covering device, which comprises a wide-brimmed hat made of an anti-UV waterproof fabric and having a memory metal wire ring fastened to the border edge of the brim thereof to facilitate collapsing, and a cap detachably fastenable to the inside of the wide-brimmed hat for capping on the head of a person. 
     2. Description of the Related Art 
     Carbon dioxide (CO2) emissions from automobiles and factories are a major contributor to the greenhouse effect and global climate change. Hydrocarbon emissions from automobiles are fragments of fuel molecules, only partially burned. Hydrocarbons react in the presence of nitrogen oxides and sunlight to form ground-level ozone, a major component of smog. Ozone irritates the eyes, nose and throat, and damages the lungs. Exposing to direct sunlight is harmful to the health. An athlete, farmer, outdoor worker, golf player or solder may be injured easily by sunlight after long exposure to the sun. Wearing a conventional sun visor, straw hat or army cap cannot effectively protect the user against the radiation of the light of the sun due to narrow shading area. Acidic rain and solar radiation are two main sources harmful to human body. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a collapsible head covering device, which uses a memory metal wire ring (or resilient metal wire ring) to support an anti-UV waterproof fabric, cloth or any other sheet member in an extended condition for hanging on the head of a user to protect the user against the radiation of sunlight without giving a burden to the head of the user, allowing the user to work conveniently under the sun. 
     It is another object of the present invention to provide a collapsible head covering device, which is easily collapsible, and allows a wide-brimmed hat to be adjustably fastened to a cap in one of various different angles for protecting the user against sunlight and rain and allowing the user to carry things by hands or to work outdoor without an umbrella or raincoat. 
     It is still another object of the present invention to provide a collapsible head covering device, which has a memory metal wire ring (or resilient metal wire ring) fastened to the border edge thereof so that the user can collapse the collapsible head covering device conveniently by twisting the memory metal wire ring (or resilient metal wire ring) and then folding up the twisted memory metal wire ring (or resilient metal wire ring). 
     It is still another object of the present invention to provide a collapsible head covering device, which can be configured to fit the body of a person, protecting the user against sun damage.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1 ,  2 , and  3 , a collapsible head covering device in accordance with a first embodiment of the present invention is shown comprising a wide-brimmed hat  2 . The wide-brimmed hat  2  is made of an anti-UV waterproof fabric, cloth or any other sheet member, comprising a semispherical crown  22 , a brim  21  extending around the semispherical crown  22  and a memory metal wire ring (or resilient metal wire ring)  211  fastened to the border edge of the brim  21 . Twisting the memory metal wire ring  211  can collapse the wide-brimmed hat  2 . The semispherical crown  22  is configured for attaching to the head of a user, enabling the wide-brimmed hat  2  to shade the user against the radiation of the sun or rain. The semispherical crown  22  defines a bottom accommodation chamber  23  for attaching to the head of a user directly. The collapsible hat further comprises a binding strap  231  partially affixed to the bottom side of the wide-brimmed hat  2  around the bottom accommodation chamber  23 , a cap  1  detachably attached to the bottom accommodation chamber  23  and secured in place by the binding strap  231 , a tubular anti-mosquito net  24  suspended from the border edge of the brim  21 , an elastic band  25  fastened to the bottom open end of the tubular anti-mosquito net  24 , and a cord lock  251  mounted at the elastic band  25  for allowing adjustment of the opening of the bottom open end of the tubular anti-mosquito net  24 . 
     Referring to  FIGS. 4-7 , a collapsible head covering device in accordance with a second embodiment of the present invention is shown comprising a wide-brimmed hat  2 , which comprises a semispherical crown  22 , a plurality of through holes  221  cut through the semispherical crown  22 , a brim  21  extending around the semispherical crown  22  and a memory metal wire ring (or resilient metal wire ring)  211  fastened to the border edge of the brim  21  for supporting the wide-brimmed hat  2  in shape, a cap  1  having a plurality of through holes  11  cut through opposing top and bottom sides thereof and attachable to the inside of the semispherical crown  22  for capping on the head of a user, and a fastening belt  3  insertable through the through holes  11  of the cap  1  and the through holes  221  of the wide-brimmed hat  2  to secure the cap  1  and the wide-brimmed hat  2  together. Thus, the collapsible head covering device can be capped on the head of a user to protect the user against sunlight or rain. Further, by means of selectively inserting the fastening belt  3  through the through holes  11  of the cap  1  and the through holes  221  of the wide-brimmed hat  2 , the wide-brimmed hat  2  can be fastened to the cap  1  in any of various different angles subject to the radiating angle of the light of the sun (as shown in  FIGS. 8 and 9 ). Further, by means of twisting the memory metal wire ring  211  and then folding up the twisted memory metal wire ring  211 , the collapsible head covering device is collapsed (see  FIGS. 10 ,  10 - 1 ,  10 - 2  and  10 - 3 ), minimizing the storage space. Further, hook and loop materials may be used for detachably and adjustably securing the wide-brimmed hat  2  to the cap  1  in any of various different angles. 
     Referring to  FIGS. 11 and 12 , a collapsible head covering device in accordance with a third embodiment of the present invention is shown comprising a flat-head cap  4 , which comprises a plurality of Velcro pads (hook and/or loop pads)  42  equiangularly located on the top side thereof, a flat sunshade  5 , which comprises a sunshade body  51  made of an anti-UV waterproof fabric, cloth or any other sheet member, a memory metal wire ring (or resilient metal wire ring)  52  fastened to the border edge of the sunshade body  51  and a plurality of Velcro pads (loop and/or hook pads)  53  located on the bottom side thereof and detachably fastenable to the Velcro pads (hook and/or loop pads)  42  of the flat-head cap  4 . The flat sunshade  5  can be collapsed by twisting the memory metal wire ring  52  and then folding it up, and then stored in the top inside space  41  in the flat-head cap  4 , facilitating carrying. 
     Referring to  FIGS. 13 and 14 , a collapsible head covering device in accordance with a fourth embodiment of the present invention is shown comprising a wide-brimmed hat  6 , a shade  7 , and a plurality of connecting strips  64  connected between the wide-brimmed hat  6  and the shade  7 . The wide-brimmed hat  6  is made of an anti-UV waterproof fabric, cloth or any other sheet member, comprising a semispherical crown  62 , a brim  61  extending around the semispherical crown  62  and a memory metal wire ring (or resilient metal wire ring)  63  fastened to the border edge of the brim  61 . The shade  7  comprises a tubular shade body  71  made of an anti-UV waterproof fabric, cloth or any other sheet member, and a memory metal wire ring (or resilient metal wire ring)  72  fastened to the bottom edge of the brim tubular shade body  71 . By means of twisting the memory metal wire ring  63 ; 72  and then folding them up, the collapsible head covering device is collapsed to minimize storage space. 
     Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
