Inflatable playpen for kids

Abstract

An inflatable playpen for kids includes an inflatable body, which includes a top ring, a bottom ring, and a plurality of side posts. The side posts are arranged vertically between the top ring and the bottom ring. The top ring, the bottom ring, and the side posts are inflatable flexible tubes that are connected to and in communication with each other. The top ring, the bottom ring, and the side posts each have an outer surface covered or enclosed with an outer covering fabric layer. After inflation, a sufficient strength and elasticity can be provided to achieve excellent protection for children. When not in use, the playpen can be deflated to change the inflatable body back into a flattened condition that occupies a small space so that stowing and transportation are made easy.
