Door or window seal

A one-piece seal adapted for frictional engagement with a rectilinear periphery of a door or a window, the periphery having planar opposing side walls and a planar bottom edge, the seal comprising:

• a planar base member having a width, a thickness, an upper surface, a lower surface, a first edge and a second edge;
• a first planar upwardly extending member extending upwardly from the base member first edge at a slightly acute angle, the first planar upwardly extending member having a top edge;
• a second planar upwardly extending member extending upwardly from the base member second edge at a slightly acute angle, the second planar upwardly extending member having a top edge;
• a first engagement member extending inwardly and downwardly from the top edge of the first planar upwardly extending member toward the second planar upwardly extending member;
• and,
• a second engagement member extending inwardly and downwardly from the top edge of the second planar upwardly extending member toward the first planar upwardly extending member;
• at least one fin extending downwardly from the base member lower surface;
• at least a first generally arcuate wall extending downwardly from the base member, the first arcuate wall connected to the base member at a first end and a second end;
• at least a second arcuate wall extending downwardly from the base member, the second arcuate wall connected to the base member at a first end and a second end;
• wherein the fins and the walls are more flexible than the base member and the first planar upwardly extending member and the second planar upwardly extending member;
• the seal having an extruded uniform longitudinal cross section selectively cut to a desired length to match a width of the door or the window;
• wherein the seal is a coextruded polymer body having portions with varying hardnesses or elasticity;
• and,
• the entire one-piece seal being resilient.

• and,
• a second engagement member extending inwardly and downwardly from the top edge of the second planar upwardly extending member toward the first planar upwardly extending member;
• a plurality of fins extending downwardly form the base member lower surface;
• a first fin extending downwardly and outwardly from the base first edge and a second fin extending downwardly and outwardly from the base second edge;
• at least a third fin extending downwardly from the base member lower surface;
• wherein the plurality of fins are more flexible than the base member and all move from a first orientation to a second orientation as the door moves from a closed to an open position;
• wherein the base member and the first planar upwardly extending member and the second planar upwardly extending member have a first hardness and the plurality of fins have a second hardness softer than the first hardness;
• and,
• the seal having an extruded uniform longitudinal cross section.
