  • Publication number: 20100176017
    Abstract: A sink organizer includes a section defining a compartment having an extendable, collapsible and/or expandable base that provides a deeper holding section with an extended base to support a long slender shaped item, such as a long-handle brush. The expandable base has a telescopic structure, which may be in the form of an accordion-like structure having annular folding sections or other form of axially collapsible or telescopic structure (e.g., a concentric coupling of a series of nested and axially interlocking cylindrical collars of gradually reducing dimensions). Suction cups provide mounting of the sink organizer onto a sink wall. A bracket is attached to the side of the sink organizer where the suction cup mounting is also provided. The bracket has a handle, which is configured to rest against the top edge of the sink, thus providing additional support for stabilizing the sink organizer after it is attached to the sink wall by the suction cups.
