Abstract
An in-line leaf trap captures the leaves and debris that are gathered by a manual or automatic suction-type swimming pool cleaner before they can enter the swimming pool's water filtering system. The leaf trap is placed in-line with the flexible hose that conducts the leaves and debris between the pool cleaner and the poolside suction connection. The in-line leaf trap is a two-piece closed container having inside a removable or integrated perforated or mesh screen debris basket. The body of the trap has two cylindrical tapered openings to mate with commonly used swimming pool cleaner hoses. The openings are oriented to ensure proper flow direction through the trap. The device floats in the pool with its top section just above the water line. The flexible hose is held floating just under the top surface of the water. By the use of flotation and ballast materials, the trap maintains a vertical operating position, with its body seal held below the water line, after being placed in that position by the pool owner or maintainer. The transparent material used in making the in-line leaf trap permits one to see when the basket is filled. Preferably, the lower body, with the attached or integral basket, is separated from the upper body and the leaves and debris are dumped out and disposed. The unit is then rejoined for further use in the pool cleaning system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
