## CPC

- E06B 7/2307: {with a single sealing-line or -plane between the wing and the part co-operating with the wing}
- E06B: FIXED OR MOVABLE CLOSURES FOR OPENINGS IN BUILDINGS, VEHICLES, FENCES OR LIKE ENCLOSURES IN GENERAL, e.g. DOORS, WINDOWS, BLINDS, GATES (shades or blinds for greenhouses A01G9/22; curtains A47H; lids for car boots or bonnets B62D25/10; skylights E04B7/18; sunshades, awnings E04F10/00)

## Abstract

A weatherstrip for use with a T-slot. The weatherstrip includes a scaling element, such as a pile of yarn, on one side thereof and a bead on the opposite side thereof. The bead includes a curved surface for engaging an interior surface of the T-slot. Preferably, the bead is a material which adheres to the weatherstrip and comprises a hot melt glue such as ethylene vinyl acetate.

## Claims

### Claim 1

A weatherstrip system, the system comprising:
an elongated support member T-slot adapted to receive a weatherstrip assembly, the T-slot defining a first lateral direction, a second lateral direction, and a depth direction, the T-slot including a set of two lips defining a top opening, a first lateral interior surface perpendicular to said lips, a second lateral interior surface perpendicular to said lips, and a bottom surface; and
a weatherstrip assembly adapted for insertion into said elongated support member T-slot, the weatherstrip assembly comprising:
a backing member;
a weatherblocking member set comprising at least one weatherblocking member; and
a flexible member;
wherein:
the backing member is elongated to define a longitudinal direction;
the backing member includes a first lateral-extending portion, a second lateral-extending portion, a top side and a bottom side;
the weatherblocking member set is connected to the top side of the backing member so that when the weatherstrip assembly is inserted into the T-slot, the weatherblocking member set will extend outwards from the T-slot;
the backing member is structured and shaped so that when the backing member is inserted into the T-slot the first lateral-extending portion will extend to contact the first lateral interior surface of the T-slot, and the second lateral-extending portion will extend to contact the second lateral interior surface of the T-slot;
the flexible member is connected to the bottom side of the backing member and extends continuously along an entire longitudinal length of the backing member; and
the flexible member is structured and shaped so that when the backing member is inserted into the T-slot the flexible member will compressively flex within a space between the bottom side of the backing member and the bottom surface of the T-slot so that the compressive flexing of the flexible member will force the backing member in a direction opposite the depth direction so that the backing member is forced into contact, along the entire longitudinal length of the backing member, with the set of lips of the T-slot;
the backing member and the flexible member are made of different materials, and wherein the flexible member is more flexible than the backing member.

### Claim 2 (depends on 1)

The system of claim 1 wherein the weatherblocking member set is a set of pile members.

### Claim 3 (depends on 1)

The system of claim 1 wherein the flexible member is made of solidified hot melt glue.

### Claim 4 (depends on 3)

The system of claim 3 wherein the flexible member is made of ethylene vinyl acetate.

### Claim 5 (depends on 1)

The system of claim 1 wherein the flexible member is self-adhering to the backing member.

### Claim 6 (depends on 1)

The system of claim 1 wherein the flexible member is located only under a central portion of the bottom surface of the backing member and does not extend laterally over the first-lateral-extending portion of the backing member or the second-lateral-extending portion of the backing member.
