DETAILED DESCRIPTION OF THE DRAWINGS
(12) FIG. 1 is an illustration depicting an example embodiment 100 having a semi-circular band, otherwise referred to a U-shaped band or a headband 114, worn on the user's head 110. A visor 112 is any piece of material that provides a surface for shading the sun from the face and neck. This surface piece, otherwise referred to as a visor is engaged with the headband 114 by way of a sliding, coupling (shown in FIG. 2 and FIG. 3). This sliding coupling has a bracket that engages with a groove 124 in the headband 114. One skilled in the art is familiar with headbands that are sometimes made of spring-steel covered with softer material such as padded fabric. Other headbands are made of flexible polymers that have the ability to return to their original shape, such polymers are said to have shape-memory. Some shape-memory polymers include nylon, high-density polyethylene and the like.
(13) The illustration in FIG. 2 depicts an exploded view of an example embodiment 100 comprising a headband 114, a bendable, flexible structure 116, the flexible structure further comprising a cross member 118 that supports a ball-joint socket 120 for engaging a ball 122 that is configured to slide in a groove 124 in the headband 114. The structure 116 supports a fabric cover, also referred to as a visor 112. One skilled in the art will understand that a similar structure to structure 116 may be covered with any number of membrane materials having ultra-violet light blocking properties.
(14) The illustration in FIG. 3 is a cross section view of an example embodiment 100 depicting the configuration and engagement of the respective components. The headband 114 is worn on the head 110. The structure 116 is engaged with the edge of the visor 112 and may be affixed to the edge with adhesive, or may be sewn in to a hem as shown in the detailed view (FIG. 3). The ball joint 122 has a ball shape that fits into the ball joint socket 120 which is fixedly engaged with the structural cross member 118 that is further engaged with the structure 116. The ball joint 122 is further slidably engaged with the groove 124 in the headband 114. One skilled in the art will be familiar with ball joints and sliding mechanisms and the like and will further understand that any number of linear motion guides or slides may be used in place of or in conjunction with the aforementioned embodiment.
(15) The illustration in FIG. 4 depicts the example embodiment 100 as worn on the head, with the visor 112 and the ball joint (not visible) slid along the groove 124 of the headband 114 and pivoted about the ball 122 and socket 120 combination such that the visor covers the right side of the head 110. One skilled in the art will understand the numerous positions that the visor 112 may be moved to according to the function of the described configuration.
(16) FIG. 5 is an illustration depicting an example embodiment 200 having a headband 214, worn on the user's head 210. A visor 212 is engaged with the headband 214 by way of a sliding, coupling (shown in FIG. 6 and FIG. 7) that engages with a rail 222 (FIG. 6, FIG. 7) and a groove 224 in the headband 214.
(17) The illustration in FIG. 6 depicts a detail view of an example embodiment 200 comprising a headband 214, and a support structure 218. The structure 218 supports a ball joint socket 220 for engaging a ball 230 that is formed cohesively with a bracket 222 that is configured to slide along a rail 228 with tabs that slide in a groove 224 under the rail 228. The structure 218 snaps into holes 226 in the visor 212. One skilled in the art will understand such a visor may be made of semi-rigid plastic capable of holding the form shown while providing sufficient structure to support the structure 218 and may be made of any number of semi-rigid membrane materials having ultra-violet light blocking properties.
(18) The illustration in FIG. 7 is an exploded view of the example embodiment 200 depicting the configuration and engagement of the respective components. The headband 214 has a rail 228 along a substantial portion of the headband 214. The structure 218 is engaged with the visor 212 by insertion of a portion of the structure through holes 226 in the visor 212. A ball-joint has a ball 230 that fits into the ball-joint socket 220 which is fixedly engaged with the structure 218. The ball 230 is fixedly engaged with a bracket 222 that slides on a rail 228 with tabs that fit in a groove 224 in the headband 214. One skilled in the art will be familiar with ball joints and sliding mechanisms and the like and will further understand that any number of linear motion guides or slides may be used in place of or in conjunction with the aforementioned embodiment.
(19) FIG. 8 is an illustration depicting a cross section of the example embodiment 200. One skilled in the art understands the manner in which the structure 218 is engaged with the ball-joint socket 220 while also engaged with the visor 212. The ball 230 is rotatably engaged with the ball joint socket 220 and further engaged with the bracket 222 that is slidably engaged with the rail 228 and the groove 224. The rail is fixedly engaged with the headband 214. One skilled in the art understands how this system may be used to position the visor 212 about the headband 214 and tilt the visor about the ball joint 220/230 to a range of angles.
(20) The illustration in FIG. 9 depicts a detail of an example embodiment 300 comprising a headband 314 that is of a material that has sufficient structure to support a ball joint socket 320 that is for engaging a ball 330 that is formed cohesively with a bracket 322, configured to slide along a rail 328 with tabs that slide in a groove 324 under the rail 328. One skilled in the art will understand such a visor may be made of semi-rigid plastic or similar material capable of holding the form shown while providing sufficient structure to support the ball-joint socket 230 and may be made of any number of semi-rigid membrane materials having ultra-violet light blocking properties.
(21) The illustration in FIG. 10 is an exploded view of the example embodiment 300 depicting the configuration and engagement of the respective components. The headband 314 has a rail 328 along a substantial portion of the headband 314. A ball-joint has a ball 330 that fits into the ball joint socket 320 which is fixedly engaged with the visor 312. The ball 330 is fixedly engaged with a bracket 322 that slides on a rail 328 with tabs that fit in a groove 324 in the headband 314. One skilled in the art will be familiar with ball-joints and sliding mechanisms and the like and will further understand that any number of linear motion guides or slides may be used in place of or in conjunction with the aforementioned embodiment.
(22) FIG. 11 is an illustration depicting a cross section of the example embodiment 300. One skilled in the art understands the manner in a ball-joint socket 320 may be molded or otherwise engaged with the visor 312. The ball 330 is rotatably engaged with the ball joint socket 320 and further molded cohesively with or otherwise engaged with the bracket 322 that is slidably engaged with the rail 328 and the groove 324. The rail is fixedly engaged with the headband 314. One skilled in the art understands how this system may be used to position the visor 312 about the headband 314 and tilt the visor about the ball joint 320/330 to a range of angles.
