Firstly, referring collectively to FIGS. 1-3, the present invention provides an inflatable playpen for kids, which comprises an inflatable body 10, which comprises: a top ring 11, a bottom ring 12, and a plurality of side posts 13, wherein the side posts 13 are arranged vertically between the top ring 11 and the bottom ring 12 and the top ring 11, the bottom ring 12, and the side posts 13 are flexible tubes that are connected to and in communication with each other and are inflatable through charging of fluid, such as air, into the tubes. The top ring 11, the bottom ring 12, and the side posts 13 are each covered or enclosed with an outer covering fabric layer 111, 121, 131, as shown in FIG. 2, so that, for illustration only, after inflation, the outer covering fabric layer 111 is closely attached to an outer surface of the top ring 11. Speaking in a clearer way, FIG. 2 provides just an example, in which the top ring 11 and the outer covering fabric layer 111 thereof are taken as an example of illustration and such a structural arrangement is equally applicable to the bottom ring 12 and the side posts 13 and the outer covering fabric layer 121, 131 thereof.
Specifically, the top ring 11 and the bottom ring 12 are each made up a plurality of inflatable flexible tubes that are sequentially connected in an end to end manner to form an annular form. The side posts 13 are each an inflatable flexible tube arranged vertically and connected to and in communication with the inflatable flexible tubes of the top ring 11 and the inflatable flexible tubes of the bottom ring 12, so that the top ring, the bottom ring, and the posts collectively form an internal chamber that extends through all the flexible tubes of them, wherein one single air valve 181 is necessarily mounted to one of the flexible tubes to enable inflation of the entire chamber or all the flexible tubes to form the playpen of the present invention in an inflated and expanded condition.
In an embodiment, the present invention further comprises an auxiliary ring 14. The auxiliary ring 14 is made of an inflatable flexible tube that is covered or enclosed with an outer covering fabric layer 141, so that after inflation, the outer covering fabric layer 141 is closely attached to an outer surface of the auxiliary ring 14, similar to the outer covering fabric layer 111 being attached to an outer surface of the top ring 11 illustrated in FIG. 2. The auxiliary ring 14 is provided with an air valve 182 for inflation and/or deflation. The auxiliary ring 14 is arranged to circumferentially surround an outer side of the bottom ring 12 and the outer covering fabric layer 141 that covers or encloses the auxiliary ring 14 and the outer covering fabric layer 121 that covers or encloses the bottom ring 12 are connected to each other, wherein the connection can be achieved with sewing or adhesive bonding or the likes. Further, the auxiliary ring 14 is preferably of a tube diameter that is greater than a tube diameter of the bottom ring 12 in order to prevent undesired tipping off the inflatable playpen by a child standing close to or leaning against an edge area of the inflatable playpen.
In an embodiment, the present invention further comprises a plurality of fixing strips 15. The fixing strips 15 each have an end connected to the outer covering fabric layer 141 that covers or encloses the auxiliary ring 14. The fixing strips 15 are arranged around an outer circumference of the auxiliary ring 14 in an equally spaced manner. Each of the fixing strips 15 has an opposite end in which a hole 151 is formed to receive a fastening element (not shown) to extend through the hole 151 to securely fix to a ground surface (such as fixing to a lawn ground), so that this invention is also useful outdoors, not being necessarily limited to use indoors.
In an embodiment, the present invention further comprises a mat 16 that is arranged horizontally such that the bottom ring 12 surrounds a circumferential edge of the mat 16. The outer covering fabric layer 121 that covers or encloses the bottom ring 12 may be connected to the circumferential edge of the mat 16 for securely coupling together so that when the present invention is raised, a child who is of an age of 1 or 2 and thus has a light body weight can be raised together with the playpen for moving to a different location, as the mat 16 may be strong enough to carry the body weight of the young child.
In the above embodiment, the outer covering fabric layers 111, 121, 131, 141 and an upper surface layer of the mat 16 are each made of a piece of Oxford cloth, and a lower surface layer of the mat 16 is made of a thermoplastic polyurethane (TPU) material. A net 17 is provided between and mounted to two adjacent ones of the side posts 13 with two opposite side edges of the net 17 connected with the outer covering fabric layers 131 that cover or enclose the two side posts 13 and upper and lower edges of the net 17 connected with the outer covering fabric layers 111, 121 that cover or enclose the top ring 11 and the bottom ring 12.
Finally, in the above embodiment, the top ring 11, the bottom ring 12, the side posts 13, and the auxiliary ring 14 are each a flexible tube made of a TPU material or a flexible tube made of a polyvinyl chloride (PVC) material. The top ring 11, the bottom ring 12, and the auxiliary ring 14 are each structured in a polygonal configuration or a circular configuration and are similar or identical in shape to each other. The polygonal configuration may include a square configuration, a hexagonal configuration (as shown in FIG. 3) or an octagonal configuration. The side posts 13 are arranged in an angularly equally spaced manner. Preferably, in case that the top ring 11, the bottom ring 12, and the auxiliary ring 14 are of polygonal configurations, the side posts 13 are respectively set up at vertices of the polygons.
The present invention provides an inflatable playpen for young children and babies, in which a plurality of inflatable flexible tubes are connected to and in communication with each other to form a unitary inflatable body and, after being inflated, respectively form a top ring, a bottom ring, and side posts vertically connected between the top and bottom rings to provide a configuration of playpen, which after being inflated, provides sufficient strength and elasticity to achieve excellent protection for young children or babies. In a condition of being not used, the playpen can be deflated, changing the inflatable body back to a flatten condition, which occupies an extremely small space, allowing for easy stowing and transportation. This invention is useful both indoors and outdoors. In addition, the top and bottom rings and the side posts are each covered with an outer covering fabric layer, which helps prevent kids from directly biting or chewing the flexible tubes so that life span of the playpen and use safety can both improved.
