Lighted inflatable ball

Claim 1

A lighted inflatable ball comprising: a inflatable ball having a wall and an air nozzle (13) therein for inflation thereof; a hollow compartment (3) provided at a central portion of said inflatable ball, said hollow compartment (3) being formed of two soft PVC membrane layers (2) joined together at side edges thereof and joined at ends thereof to said wall, with a plurality of projecting rings (14) being molded on outer sides of upper and lower ends of said soft PVC membrane layers (2), said hollow compartment (3) being closed at a lower end thereof near the center thereof by a closed zone (4), said hollow compartment (3) being closable at an open upper end thereof by a waterproof closure (31); a battery cell holder (5) insertable in said hollow compartment (3), an ON-OFF switch (10) being provided on said battery cell holder (5); a blockading member (61) molded on a side of said hollow compartment (3), cell conducting wiring (71) from said battery cell holder (5) passing air-tightly through said blockading member (61); and a plurality of lamp bulbs (6), each fixed on one of said projecting rings (14), bulb conducting wiring (7) from said lamp bulbs (6) being connected with said cell conducting wiring (71); wherein said cell conducting wiring (71) from said battery cell holder (5) is fused and molded between the soft PVC membrane layers (2) at a side of said hollow compartment (3) at said blockading member (61), whereby airtight passage of said cell conducting wiring (71) out through said soft PVC membrane layers (2) of said hollow compartment (3) is provided for preventing air permeation from said inflatable ball into said hollow compartment (3); and wherein, when said inflatable ball is fully inflated, tension is exerted by the wall of the inflatable ball on the soft PVC membrane layers (2) of the hollow compartment (3) to thereby press the soft PVC membrane layers (2) inward to narrow the hollow compartment (3) for positioning the battery cell holder (5) therein.
