Abstract

A frame-supported back-pack for infant-carrying involves front and rear fabric-covered leaves (3,5) that hinge apart with the infant's seat (4) suspended between them. The front and rear leaves (3,5) are defined respectively by the upright section (8) of an L-shape tubular-metal member (7) and a tubular-metal member (11) hinged to the base section (9) of the L-shape member (7). A semicircular aperture (20) in the rear of the pack opens into the cavity (24) of a partially-domed shell (19) which is inset into the pack over part of the base section (9) of the L-shape member (7). The pack is held upright when standing on its base on the ground by insertion of the user's foot into the cavity (24) to press down onto the base section (9) under the aperture (20).
