Abstract

A one-piece seal for use on the bottoms of doors or windows of uniform cross-section has a planar base and upwardly extending members on each side of the base with engagement members at the top of the upwardly extending members. The seal also has downwardly extending fins and semicircular walls to engage a threshold. The seal is held upon a door by action of the flexible engagement members being pressed against the sides of the doors by the upstanding members.

Claims

1. A one piece seal adapted for use at the rectilinear periphery of a door or window, the seal having a substantially uniform cross section, 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;

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;

the entire one piece seal being resilient; and

,

wherein the base member and the first planar upwardly extending member and the second planar upwardly extending member have a first hardness and the first engagement member and the second engagement member have a second hardness softer than the first hardness.

2. The seal of claim 1 additionally comprising a fin extending downwardly and outwardly from the base first edge and a fin extending downwardly and outwardly from the base second edge.

3. The seal of claim 1 wherein the first arcuate wall has a lower surface and a fin extending downwardly from its lower surface.

4. The seal of claim 3 having at least a second arcuate wall extending downwardly from the base member, the second arcuate wall connected to the base member at both ends and having a lower surface and a fin extending downwardly from its lower surface.

5. The seal of claim 1 wherein the first engagement member has a curved portion extending downwardly toward the base member and the second engagement member has a curved portion extending downwardly toward the base member.

6. The seal of claim 1 wherein the first engagement member and the second engagement member are more flexible than the base member and the first planar upwardly extending member and the second planar upwardly extending member.

7. The seal of claim 4 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.

8. The seal of claim 7 wherein the base member and the first planar upwardly extending member and the second planar upwardly extending member have a first hardness and the fins and the walls have a second hardness softer than the first hardness.

9. The seal of claim 1 wherein the seal is an extruded polymer body.

10. The seal of claim 9 wherein the seal is a coextruded polymer body having portions with different properties of hardnesses or elasticity.

11. The seal of claim 1 wherein the seal is adapted to be held on an associated door or window by the engagement members and using no fasteners.
