Abstract
A filter support member includes a plurality of core members and a hinge positioned between at least two of the plurality of core members. The hinge allows pivotal movement of the at least two core members relative to one another about a hinge axis associated with the hinge. The plurality of core members are positionable in an operational position to form a substantially cylindrical body and are further positionable in a stored position to form a substantially flat sheet. The substantially flat sheet occupies a volumetric envelope less than a volumetric envelope of the substantially cylindrical body.
Claims32
An apparatus for supporting filter media, the apparatus comprising:
- a plurality of core members;
- a hinge positioned between at least two of the plurality of core members to allow pivotal movement of the at least two core members relative to one another about a hinge axis associated with the hinge;
- wherein the plurality of core members are positionable in an operational position to form a substantially cylindrical body;
- wherein the plurality of core member are positionable in a stored position to form a substantially flat sheet, the substantially flat sheet occupying a volumetric envelope less than a volumetric envelope of the substantially cylindrical body.
A filter comprising:
- a filter support member having a substantially cylindrical body comprised of a plurality of core members, each of the plurality of core members pivotally attached to at least another of the plurality of core members;
- and
- a filter media positioned adjacent to or in contact with the substantially cylindrical body.
