DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 through 3, a baby walker 1 of the present invention is generally comprised of a top inflatable ring 14, an intermediate inflatable ring 13, a lower inflatable ring 12 and a base inflatable ring 11. The inflatable rings 11 through 14 are made of colorful and inflatable heavy-duty vinyl and properly designed in different size, that is the top inflatable ring 14 is the smallest one and the base inflatable ring 11 is the biggest one. The top inflatable ring 14 is the smallest in size, defining therein a center hole suitable for insertion of a baby, having a male Velcro strip, hook, member 142 on the bottom, a safety valve 143 at one side, an unitary inflatable head-rest portion 146 laterally upstanding therefrom for supporting baby's head, and a male snap fastener 145 at a lower position. The intermediate inflatable ring 13 is relatively larger than the top inflatable ring 14, defining therein a center hole suitable for insertion of a baby, having a female Velcro strip member 131 on the top, a male Velcro strip, loop, member 132 on the bottom, a safety valve 133 at one side, a female snap fastener 134 at an upper position corresponding to the male snap fastener 145 of the top inflatable ring 14, and a male snap fastener 135 at a lower position. The lower inflatable ring 12 is relatively larger than the intermediate inflatable ring 13, having a female Velcro strip member 121 on the top, a male Velcro strip member 122 on the bottom, a safety valve 123 on the one side, a female snap fastener 124 at an upper position corresponding to the male snap fastener 135 of the intermediate inflatable ring 13, a male snap fastener 125 at a lower position, and a flat surface portion 126 at the center with two round holes 1261, 1262 made thereon. The flat surface portion 126 serves as a seat for a baby to sit while a baby's legs are respectively inserted through the two round holes 1261, 1262 thereon. The base inflatable ring 11 is relatively larger than the lower inflatable ring 13, having a female Velcro strip member 111 on the top, a safety valve 113 at one side, a female snap fastener 114 at an upper position corresponding to the male snap fastener 125 of the intermediate inflatable ring 13, a plurality of vinyl holders 116 on the bottom for holding a tubing 117 which is secured to the vinyl holders 116 by screw means 118 and has a plurality of casters 119 equidistantly firmly secured thereto at the bottom. According to the present invention, the tubing 117, the screw means 118 are made of rustless metal and the casters 119 are made of rigid plastic material. Therefore, either of the inflatable rings 11 through 14 can be separately used as an aid for swimming or a lifesaver.

The process to set up the inflatable rings 11 through 14 into a baby walker is outlined hereinafter. The lower inflatable ring 12 is mounted on the top of the base inflatable ring 11 permitting the female Velcro strip member 111 and the female snap fastener 114 of the base inflatable ring 11 to respectively fasten up with the male Velcro strip member 122 and the male snap fastener 125 of the lower inflatable ring 12. Then, attach the intermediate inflatable ring 13 to the lower inflatable ring 12 at the top, permitting the female Velcro strip member 121 and the female snap fastener 124 of the lower inflatable ring 12 to respectively fasten up with the male Velcro strip member 132 and the male snap fastener 135 of the intermediate inflatable ring 13. Finally, the top inflatable ring 14 is attached to the intermediate inflatable ring 13, permitting the male Velcro strip member 142 and the round button 1451 of the male snap fastener 145 of the top inflatable ring 14 to respectively fasten up with the female Velcro strip member 131 and the female snap fastener 134 of the intermediate inflatable ring 13. Thus, a bay walker of the present invention is set up. By means of the connection of a male Velcro strip member with a female Velcro strip member and a male snap fastener with a female snap fastener, each two inflatable rings are firmly connected twice .
