Abstract: A sunshade has ribs which emanate from a hub and are connected intermediate their ends to struts which are in turn connected to a center sleeve. When the sleeve is remote from the hub, the ribs and struts lie alongside each other in a collapsed position in which they are generally parallel to the axis of the hub. However, as the sleeve is moved upwardly toward the hub, the struts swing outwardly and push the ribs outwardly. Indeed, the struts pass through an over center position before the sleeve comes against the hub, and when the sleeve is against the hub, the ribs are in an extended position wherein they radiate from the hub. Each rib at its outer end has a rib extension connected to it, and these rib extensions fold between extended positions, wherein they form continuations of their respective ribs, and folded positions wherein they lie alongside their respective ribs. A fabric cover is connected to the ribs and rib extensions and folds with them.

Abstract: A collapsible headgear includes rib members having somewhat spherical inner ends that fit into radial sockets in a hub, thus enabling the rib members to fold from a collapsed condition, in which they lie along the hub axis, to an erected condition in which they project from the hub. The movement from one condition to the other is produced by a collar and struts that extend between the collar and the rib members. The struts are connected at their outer ends to the rib members by clevises, and have generally spherical inner ends that fit into radial sockets in the collar. Consequently, when the collar is moved upwardly toward the hub, the struts are driven outwardly, and the struts in turn drive the rib members to their erected positions. A cover extends over the rib members, and the cover, rib members, and struts, when erected, are supported above the user's head by supports which extend downwardly from the struts and at their lower ends are fitted with a headband.
