<P>PROBLEM TO BE SOLVED: To provide a window screen with a stopper for preventing escape of infants, solving the problem of the conventional window screen in which even infants are easy to open-close it and pushing of the mesh portion allows it to be broken even by infants so there is a risk that infants may go out to a veranda during time when we take our eyes off them. <P>SOLUTION: (a) A window screen with a stopper arranges vertical bars in the mesh portion to form a vertical stripe pattern, which can prevent infants from breaking the mesh to escape. (b) A switch-type stopper is installed on either right or left side of vertical frame parts of the window screen, which can prevent infants from opening the screen to go outside by themselves. <P>COPYRIGHT: (C)2012,JPO&INPIT |
