  • Patent number: 10465406
    Abstract: An intake shield assembly for inhibiting a pool skimmer from being plugged includes a pipe that is extended into an intake of a pool skimmer thereby inhibiting objects from entering the intake. A pair of arms is provided and each of the arms is coupled to the pipe. Each of the arms abuts a wall of the pool when the pipe is extended into the intake thereby inhibiting the pipe from being drawn fully into the intake. An elbow is provided and the elbow is positioned in the intake of the pool skimmer. The elbow is fluidly coupled to the pipe when the pipe is extended into the intake. In this way the elbow inhibits objects from plugging the intake.
