Claims4
For combination with a stormwater catch basin having a cover frame, a cover gutter grate supported by the frame, and a cover curb inlet adjacent the grate, a catch basin filter assembly comprising:
- a first open frame element having a plan area substantially co-extensive with the plan area of the stormwater catch basin cover gutter grate;
- a second open frame element spaced-apart from said first open frame element and having a plan area substantially co-extensive with the plan area of the stormwater catch basin cover curb inlet;
- a mesh fabric filter element connected to and carried by said first and second open frame elements and having a plan area substantially coextensive with the combined plan areas of said first and second open frame elements;
- and
- multiple clamp devices for removably connecting said first open frame element to the catch basin cover frame and to the catch basin cover gutter grate,
- said mesh fabric filter element functioning as a hinge connected to and positioned intermediate said first and second open frame elements.
A stormwater curb and gutter-type catch basin installation in a drainage system, and comprising:
- a catch basin inlet cover frame element having a substantially rectangular plan configuration;
- a catch basin inlet cover gutter grate element supported by said catch basin inlet cover frame element;
- a catch basin inlet curb opening element within said catch basin inlet cover frame element and contiguous to said catch basin inlet cover gutter grate element;
- a filter assembly first open frame element positioned upon and supported by said catch basin inlet cover gutter grate element;
- a filter assembly second open frame element positioned over said catch basin inlet curb opening element and hingedly connected to said filter assembly first open frame element;
- a unitary mesh fabric filter element connected to and essentially co-extensive with said filter assembly first and second open frame elements;
- and
- multiple clamp elements removably connecting said filter assembly first open frame element to said catch basin inlet cover frame element and to said catch basin inlet cover gutter grate element,
- said filter assembly first and second open frame elements being hingedly interconnected by said unitary mesh fabric filter element.
