However, such description should be construed as also describing compositions or processes as “consisting of” and “consisting essentially of” the enumerated ingredients/steps, which allows the presence of only the named ingredients/steps, along with any unavoidable impurities that might result therefrom, and excludes other ingredients/steps.

[0025] Numerical values in the specification and claims of this application should be understood to include numerical values which are the same when reduced to the same number of significant figures and numerical values which differ from the stated value by less than the experimental error of conventional measurement technique of the type described in the present application to determine the value.

[0026] FIG. 1 illustrates a typical existing sliding door system 100 often found installed in a structure. The system 100, includes a frame 102, an interior facing track 104, and an exterior facing track 106. The tracks 104 and 106 are parallel and may substantially extend along the entire length L of the frame 102. These door systems often include a first door 114 associated with the interior track 104 and a second door 116 associated with the exterior track 106. The system 100 of FIG. 1 illustrates the first door 114 in a closed position. That is, the first door 114 and second door 116 are arranged such that the combination of the offset doors extend along the length L of the door frame 102. The doors 114 and 116 may overlap at a centralized position 110 of the frame 102 and include a vertically extending seal (not shown) to prevent drafts, debris, and the like from entering the structure between a gap created between the overlapping doors.

[0027] The first door 114 is configured to slidably move along the track 104 of the frame 102 from a closed position (as shown in FIG. 1) to an open position (not shown). In the open position, the first door 114, substantially overlaps the position of the second door 116 and provides an open space located where the first door 114 was positioned in the closed state. The open space allows for an exchange between the outside environment and interior environment of the structure allowing for a person to exit or enter the structure. In some systems, the second door 116 is fixed, meaning that it does not slide with respect to positions along its associated track 106. In other systems, the second door 116 is also configured to slidably move along its associated track 106.

[0028] It is to be appreciated, that a recess 120 is created due to the offset nature of the first door 114 and second door 116 in the closed position. That is, a portion of the interior track 104 within the recess 108 is unoccupied by the door 114. Drafting air, dust, odors, and pests may enter the structure through gaps between the bottom 124 of first door 114 and its associated track 104 and through gaps between the bottom 126 of second door 116 and its associated track 106 adjacent to the recess 120 formed along door frame base 128.

[0029] FIGS. 2-7 illustrate a preferred embodiment of a draft stopper 200 of the present disclosure. Of course, variations to the draft stopper are contemplated by the disclosure. The foldable door draft stopper 200 is compatible with the typical sliding door systems illustrated in FIG. 1. Of course, the foldable draft stopper can be adapted for use with swinging or rotatable doors or French door systems as well. The draft stopper 200 preferably includes a longitudinally extending body 202 with a first portion 204, a second portion 206, and a central connecting portion 208 which may be hollow. The longitudinally extending body 202 has a length D extending from the first end 204 to the second end 206. In some embodiments, the length D of the longitudinally body can be greater than the length L of the door system 100. In other embodiments, the length D of the longitudinally body is about equal to the length L of the door system 100. In some embodiments, the length L of the body 202 is from about 65 to about 75 inches. In more particular embodiments, the length L of the body 202 is about 71.5 inches. Thus, length D can vary from 65 to over 75 inches or other dimensions contemplated by the disclosure.

[0030] The longitudinally extending body 202 preferably includes an exterior body casing 203 configured to contain at least one material 205 therein. That is, the body casing 203 is a bag like structure which is filled with at least one material and then closed. In some embodiments, the body casing 203 is composed of a fabric. In other embodiments, the body casing 203 is composed of a waterproof material. In other embodiments, the body casing 203 is composed of a combination of materials. The body casing 203 defines the shape of the longitudinally extending body 202. In some embodiments, the body casing 203 is substantially cylindrical in shape.

[0031] The hollow body casing 203 may also contain at least one thermal insulating material 205. Insulating materials include, but are not limited to fiberglass, wool, cellulose, natural fibers, polystyrene, polyurethane, polyester, cotton, foams, and the like. In some embodiments, the insulating material is composed of polyester.

[0032] The body casing 203 may contain at least one weighted material 205. The weighted material is provided to the body 202 in order to provide resistance of the body 202 to motion. That is, the draft stopper 200 due to its weighted materials stays in place along the edge of a door system and does not move due to incoming drafting air. Weighted materials include but are not limited to sand, gravel, stones and the like, metal beads such as lead, steel, iron, brass, and the like. In some embodiments, the weighted material is sealed within a sack and then the sack is placed within the body casing 203 before sealing the body casing 203. In some preferred embodiments, the body casing 203 contains a combination of insulating and weighted materials.

[0033] The connection portion 208 forms an empty space between first portion 204 and second portion 206 which enables the stopper to easily fold in half. (See FIGS. 2-4).

[0034] Preferably, first and second portions 204 and 206 are sewn or otherwise sealed on inside positions 210, 212 to keep the stuffing 205 inside the first and second portions and from entering the hollow central portion 208.

Example

[0035] Referring now to FIGS. 5-7, the foldable draft stopper 200 being used with a door system having a first door 300 and a second door 304 in accordance with the preferred embodiment of the disclosure is shown.

[0036] The foldable draft stopper prevents unwanted debris, drafts, etc. from entering a residence or building via gaps about a base of the door.

[0037] FIG. 5 shows the foldable draft stopper positioned in a fully engaged, longitudinally position along the bottom edge of a door frame 301 with the first and second portions 204, 206 substantially filling the bottom edge 302 of the door frame 301. First portion 204 is positioned adjacent an abutting first door 300, while second portion 206 is positioned adjacent an abutting second door 304. Both first and second portions 204, 206 are positioned on the same side of door frame 301 in an engaged position when the doors are closed.

[0038] FIG. 6 shows the second portion 206 partially folded away from the door frame 301 about central portion 208, while FIG. 7 shows the second portion 206 completely folded over and in parallel alignment with the first portion 204, thereby allowing door 304 to be rotated or slid to an open position to allow ingress and egress through door 304. First portion 204 remains adjacent to the first door 300 when the second door 304 is slid or rotated open. Neither first portion 204 and second portion 206 travel or move with either door while being opened or closed.

[0039] The exemplary embodiment has been described with reference to the preferred embodiment. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the exemplary embodiment be construed as including all such modifications and alterations insofar as they come within the scope of the above disclosure or the equivalents thereof.
