Abstract:
An aquarium-maintenance system comprising:an aquarium;a filtering cannister that is at least partly transparent for visual observation of the cleanliness of aquarium water and the filtering medium in the filtering cannister;the filtering cannister having a filter portion, a filter-inlet portion and a filter-outlet portion;a cannister-inlet conveyance having a quick-joint inlet attachment that is in fluid communication intermediate the filter-inlet portion and a drain conveyance that is fluid communicative from at least one aquarium;the drain conveyance being at least partly transparent for visual observation of cleanness of the aquarium water in the drain conveyance;a cannister-outlet conveyance having a quick-joint outlet attachment in fluid communication intermediate the filter-outlet portion and a circulator conveyance;a system pump having predetermined pumping capacity in fluid communication intermediate the circulator conveyance and a fill conveyance that is fluid communicative to the aquarium;the fill conveyance being at least partly transparent for visual observation of cleanness of the aquarium water in the fill conveyance;at least one handling member on the filtering cannister; anda filtering cleaner on the filtering cannister;the quick-joint inlet attachment is a tubular inlet connection;the quick-joint outlet attachment is a tubular outlet connection;the tubular inlet connection has a squeeze-release with a pair of bevel rods that are oppositely disposed collinearly on an inside periphery of a release-squeezable spring cylinder with which the bevel rods are spring-pressured radially inward to sliding contact of ring-side walls of the bevel rods against a ring washer that buttresses a washer-backed O-ring to force the ring washer and the washer-backed O-ring to travel orthogonally to the bevel rods by spring-resilience travel of a cylindrical wall of the spring cylinder from ellipticity for squeeze-release mode to circularity for sealing mode of the tubular inlet connection selectively;the washer-backed O-ring is buttressed against a circumferentially inside sealing perimeter of a base cylinder;a first tube has an outside periphery that is leakproof-affixed to an inside sealing periphery of a first end of the base cylinder;a resilient tube is positioned circumferentially intermediate the inside periphery of the spring cylinder and an outside periphery of the base cylinder;the base cylinder has radial slide walls with which sides of the bevel rods have backup-sliding contact intermediate the squeeze-release mode and the sealing mode of the tubular inlet connection;the resilient tube has radial apertures through which the bevel rods are extended inward radially from the spring cylinder;the ring-side walls of the bevel rods have bevels with predetermined bevel angles to bevel-drive the ring washer from oppositely disposed sides against the washer-backed O-ring circumferentially; andthe washer-backed O-ring is rubber-like sealing material that has circumferential backing for uniform sealing contact with the inside sealing perimeter of the base of cylinder and for uniform sealing contact with an outside sealing surface of a second tube having a sealing end proximate the inside sealing perimeter of the base cylinder.
