Abstract
Abstract A combination pack and seat is convertible for use as a table engaging child seat, and back pack type child carrier, and a free standing child seat. The combination pack and seat includes a pair of spaced side frame members extending in parallel relation and each connected by a radiused bend portion with an obliquely extending ground support foot. An upper end of each of the side frame members are connected by an arcuate curved portion with a top frame member. The top frame members extend in spaced parallel relation and are connected by a transverse end bar to form a rectangular channel. A child carrying pouch formed from a flexible material is suspended from the top frame members and the transverse end bar, within the rectangular channel. A pair of pivotal struts are mounted by pivotal detent mechanisms adjacent the arcuate curved portion on each of the side frame members. The pivotal struts each terminate in a non-slip tip adapted for ground engagement, and include a transversely extending abutment member adapted for engagement with a bottom surface of a table top. A pair of adjustable padded shoulder straps are provided for carrying the frame in a back pack fashion. Telescopic extension members are mounted for selective extension and retraction in the top frame members and each terminate in a non-slip tip. A table top may be clamped between the extension members and the pivotal strut abutment members.
