DETAILED DESCRIPTION

In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted. or simplified in order not to obscure the embodiment being described. In addition, to the extent that orientations of the embodiments are described, such as “top,” “bottom,” “front,” “rear,” “right,” and the like, the orientations are to aid the reader in understanding to embodiment being described, and are not meant to be limiting.

Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows an end view of a foot end 22 of a sleeping bag 20. The sleeping bag 20 includes a top 24 and a bottom 26.

The sleeping bag 20 shown in the drawings is of a standard configuration, and in the embodiments shown in the drawings is a generally rectangular bag formed by the top 24 being folded over the bottom 26, and connection of the top and the bottom by a primary zipper 28. This type of structure is conventional, and is known in the art. A sleeping bag may include a variety of other features, or may be shaped in another manner.

Although the configuration of the sleeping bag 20 in the drawings utilizes a fold-over construction with connection by a zipper, many other configurations may be utilized. For example, a bag may be formed in which a connection is made at the top or bottom of the sleeping bag, instead of along the side edges. A sleeping bag may be closed by an attachment structure other than a zipper. In addition, a sleeping bag may be folded and sewn or otherwise permanently connected. The top and bottom of the sleeping bag may be formed of two different pieces, and may be connected along their edges to form a sleeping bag. Furthermore, although shown as a rectangle, the sleeping bag may have any shape, including a mummy shape, a more square, or “double” shape, or other configurations.

As is conventional in sleeping bags, the primary zipper 28 includes upper and lower zipper tapes 30, 32 that are typically sewn to the top 24 and the bottom 26, respectively. In accordance with an embodiment, a secondary attachment structure is provided on the sleeping bag 20. The secondary attachment structure is a mechanism that permits the sleeping bag 20 to be opened without opening the primary zipper 28. This secondary attachment structure may be, for example, hook and loop fasteners, toggle and loop fasteners, clasps, clips, buttons, snaps, or other suitable fasteners.

In accordance with an embodiment, the secondary attachment structure is a zipper 34.

The secondary zipper 34 includes an upper zipper tape 36 and a lower zipper tape 38. In the embodiment shown in the drawings, the lower zipper tape 38 for the secondary zipper 34 is attached to the upper zipper tape 30 for the primary zipper 28, and the upper zipper tape 36 of the secondary zipper is connected to the top 24 of the sleeping bag 20. Thus, the secondary zipper 34 and the primary zipper 28 extend side-by-side. In an alternate embodiment, the secondary zipper 34 is attached between the lower zipper tape 32 for the primary zipper 28 and the bottom 26 of the sleeping bag.

In the embodiment shown in the drawings, the secondary zipper 34 is positioned at the foot end 22 of the sleeping bag 20. However, the secondary zipper 34 or other suitable secondary attachment structure may continue beyond the foot end 22, and/or may be positioned at another location on the sleeping bag, such as along one or both of the sides of the sleeping bag, or at a portion of the top of the sleeping bag. In addition, the secondary zipper 34 or other suitable secondary attachment structure may be positioned away from the primary zipper 28.

In an embodiment, the secondary zipper 34 may be opened to provide ventilation for the sleeping bag 20. This ventilation may be provided without opening of the primary zipper 28.

In accordance with an embodiment, a mesh panel 40 (FIG. 2) is connected to the back side of the upper and lower zipper tapes 36, 38 for the secondary zipper 34. In the embodiment shown in the drawings, when the secondary zipper 34 is closed, the mesh panel 40 is positioned inside the sleeping bag 20. However, the mesh panel 40 may alternatively be positioned outside the sleeping bag 20 or in a pocket (not shown) on or in the sleeping bag. When the secondary zipper 34 is opened, the mesh panel 40 connects the top 24 of the sleeping bag 20 to the bottom 26 (via the primary zipper 28).

The mesh panel 40 may be formed of a suitable mesh or screen material that allows air circulation into the sleeping bag 20 when the secondary zipper 34 is opened. By providing a mesh panel 40, air circulation may be provided, but the top 24 and bottom 26 of the sleeping bag 20 remain connected together, preventing a loss of shape of the sleeping bag and a limb of an occupant of the sleeping bag from extending out of the opening. The mesh panel 40 also provides blocking of insects, rodents, snakes, and other animals when the secondary zipper 34 is opened.

When the secondary zipper 34 is closed, the mesh panel 40 folds against itself, and is stored at the foot end 22 of the sleeping bag. The primary zipper 28 may be opened, such as shown in FIG. 3, to provide access to the inside of the sleeping bag 20 in a conventional manner.

The secondary zipper 34 provides. Ventilation for the sleeping bag 20 without requiring opening of the primary zipper 28. Use of the mesh panel 40 permits air to circulate through the sleeping bag 20 while maintaining a connection between the top 24 and bottom 26 of the sleeping bag, and preventing a user from sliding out of the sleeping bag. In addition, protection against insects and small animals from entering the sleeping bag while open is provided by the mesh panel 40.
