ABSTRACT:
The present invention relates to a hard hat which may be collapsed and easily stored when not in use. The hat uses a brim as a structural support, multiple curved segments and means for locking the segments into place. The multiple curved segments have raised and lowered portions, decreasing radii, and a common pivot point on the sides of the brim. In the collapsed position all the segments are stacked on one side of the brim, but when the hat is to be extended, the first curved segment is rotated about the common axis. As it is rotated a lowered portion on the back inner surface of the segment engages a raised portion on the front outer face of the next segment and it is drawn (as are the remaining segment) along with the first segment. Once the first segment has reached its position on the further side of the brim, the first segment is then locked into place and the hat is complete.
