Abstract: A cover for the protection of an infant comprises a central hub member which is pivotally connected at one end to an extendable and collapsible support frame made up of link arms and pivotally, flexible connected frame ribs. The ribs reside in channels in an exterior surface covering of mesh cloth or transparent or opaque material. The hub member is connected, at its other end, to a string-like line which extends through an opening on the top of the cover. The line is attached to a handle. With the cover in a collapsed position, the handle is pulled upwards, which causes the attached line and the hub to move upward. This results in the link arms pivoting the frame ribs outward and upward. Upon continued pulling on the handle, the hub is pulled into and secured within the opening, causing the frame and surface covering to become fully extended. The cover forming the resulting enclosed space is lightweight and can readily be secured to a crib or simply placed on a bed, the ground, or other unprotected area.
