Description

BACKGROUND OF THE DISCLOSURE

The present disclosure relates a device to prevent drafts from entering a structure. It finds particular application in conjunction with sliding door systems and preventing drafting air, bugs, dust, and unwanted odors from entering a building or residence originating from the outside environment and further assisting in the temperature regulation of the structure. However, it is to be appreciated that the present exemplary embodiment is also amenable to other like applications.

Sliding door systems are installed in many residential and commercial structures as a way of providing access into and out of the structure. Door systems of this type are usually double door systems wherein each door is provided with at least one glass pane closed within a metal or plastic border. Generally, one door is fixed and the other is slidable between open and closed positions within the frame of the door system. That is, the sliding door includes a frame including a plurality of adjacent tracks where each track is associated with at least one door that is slidably attached within the frame. The door system provides access to outside by sliding a door along the track to an open position.

The base of the sliding door system, where each door contacts the track, is susceptible to gaps and allows for unwanted air (i.e., drafts), bugs, or the like, originating from the outside environment to enter the structure. Drafting air, especially in the wintertime, may contribute to a drop in temperature within the structure leading to increased heating and energy costs and discomfort.

Thus, it is desirable to provide a device that may be placed about a sliding door system to prevent drafts and unwanted outside annoyances from entering the structure while being easily moved to allow one to freely open and close the sliding door.

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.

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.

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.

The sliding door draft stopper 200 also includes a longitudinally extending flap portion 220 with a flap first end 224, a flap second end 226, and a side edge 227. The longitudinally extending flap portion 220 has a length F extending from the flap first end 224 to the rear end flap second end 226. In some embodiments, the length L of the longitudinally extending body 202 is greater than the length F of the flap portion 220. In some embodiments, the length F of the flap portion is from about 30 to about 40 inches long. In some embodiments, the length F of the flap portion is about 34 inches long.

The flap portion 220 may include a flap casing 223 configured to contain at least one material therein. That is, the flap casing 223 is a bag like structure which may be filled with at least one material and then closed and/or sealed. In some embodiments, the flap casing 223 is composed of a fabric. In some embodiments, the flap casing 223 is composed of a waterproof material. In other embodiments, the flap casing 223 is composed of a combination of materials. The flap casing 223 defines the shape of the flap portion 220. In some embodiments, the flap casing 223 is substantially ovalic in shape.

The flap casing 223 may contain at least one thermal insulating material. 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.

The flap casing 223 may contain at least one weighted material. The weighted material is provided within the flap portion 220 in order to keep the flap portion 220 in an engaged position 221 within the sliding door system recess 120 (discussed in greater detail below). 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 flap casing 223 before sealing the flap casing 223. In some preferred embodiments, the flap casing 223 contains a combination of insulating and weighted materials.

The flap portion 220 is hingedly connected at connection living hinge 225 along the side edge 227 to a portion of the top 207 of the longitudinally extending body 202. The hinged connection allows the flap portion 220 to rotate about the connected side edge 227 in the direction of the arrow 230 of FIG. 2. That is, the flap portion 220 may rotate from an unengaged position, shown in FIG. 3, to an engaged position shown in FIG. 4 and the dotted outline 221 of FIG. 3.

In some embodiments, the hinged attachment 225 is made by fastening the body 202 and flap portion 220 together along the side edge 227 and top 207 using stitches, such as those made in sewing. In other embodiments, the body 202 and flap portion are bonded together along side edge 227 with an adhesive.

In some embodiments, the body 202 and flap portion 220 are removably attached. That is, the flap portion 220 may be easily removed and attached to the longitudinally extending body 202. In some embodiments, the removable attachment is a hook and loop attachment. In other embodiments, the removable attachment may be provided by a plurality of snap fasteners along the side edge 227 and corresponding fasteners positioned along a portion of the top 207. In still other embodiments, the longitudinally extending body 202 and flap portion 220 may be attached by a clasp locker, commonly known as a zipper.

When the longitudinally extending body 202 is laid against the bottom edge 128 of the sliding door frame 102 the longitudinally extending body 202 abuts the bottom edge 124 of the first door 114 and along the length L of the frame 102. The flap portion 220 may be moved to the engaged position 221 of FIGS. 3 and 4. In the engaged position 221, the flap portion 220 occupies the recess 120 and abuts the bottom edge 126 of the second door 116. In this way, the draft stopper 200 is positioned to prevent unwanted air, debris, etc. from entering the structure through gaps between the bottoms 124 and 126 of doors 114 and 116, respectively.

The hinged attachment 225 also allows a person to easily move the flap portion 220 from an engaged position to an unengaged position and allow for opening of the sliding door system 100. That is, in some instances, the flap portion 220 may hinder the first door 114 from sliding along its associated tack 104 (within the recess 120) to an open position unless the flap portion 220 is moved to its unengaged position.

In some embodiments, the flap portion 220 may contain a longitudinally extending rod 232 within the flap casing 223. The rod 230 provides rigidity and a security feature when the flap 220 is in an engaged position that prevents the door 114 from sliding to an open position along the track 104. In this way, unwanted intruders may be thwarted by the security measure when trying to enter a structure through the sliding door system. The rod 232 may be made of wood, metal, or the like.

In some embodiments, rear end 206 of the body 202 extends beyond the flap second end 226 of the flap portion 220. In this way, the longitudinally extending body 202 may extend along the base 128 of the door frame 102 past the recess portion 120 for additional thermal coverage of the frame.
