Abstract: A device for affixing sunshades to a cap includes a pair of sunshades fixed to an upper rib with exposed left and right side portions, left and right side anchor members which are affixed to the brim of the cap and have respective clip elements that clip onto the exposed portions of the upper rib of the sunshades to hold the sunshades in position on the brim of the cap. The upper rib also has left and right side cam members positioned on the outer sides of the clip elements which have cam surfaces that abut against stationary surfaces of the anchor members to provide detent positions for maintaining the sunshades stably in either the operative position or an upward, storage position. The anchor members can be clip members or provided with self-adhesive surfaces for attachment to the brim of the cap. The assembly can be pre-assembled with fabricated caps or provided in a retrofit kit for convenient installation by wearers on their own caps.
