Abstract
A zipper assembly is used to releasably attach a bag liner to a sleeping bag to retain the bag liner within the sleeping bag and to expand the bag interior to compensate for volume lost by insertion of the bag liner. The zipper assembly includes first and second pairs of spaced rows of liner zipper teeth. Two rows are secured to the existing rows of bag zipper teeth by two zipper slides. A third zipper slide releasably secures two of the other rows of liner zipper teeth to permit an individual to enter and exit the bag liner. In another embodiment of the invention, a protective cover is releasably secured to a bag by a zipper assembly.

In combination:
- a sleeping bag defining a bag interior, a bag head opening, and a bag longitudinal opening extending longitudinally along the sleeping bag and communicating with said bag head opening and said bag interior, said bag longitudinal opening being defined by first and second spaced elongated bag edges, said sleeping bag including a first row of bag zipper teeth disposed along said first spaced elongated bag edge and a second row of bag zipper teeth disposed along said second spaced elongated bag edge;
- a removable bag liner positioned in said bag interior defining a liner interior having a liner head opening and a liner longitudinal opening extending longitudinally, along the bag liner and communicating with said liner head opening and said liner interior, said liner longitudinal opening being defined by first and second spaced elongated liner edges;
- and
- a zipper assembly attached to said bag liner, said zipper assembly including first and second pairs of spaced rows of liner zipper teeth, the first pair of spaced rows of liner zipper teeth secured to said first spaced elongated liner edge and parallel thereto and the second pair of spaced rows of liner zipper teeth secured to said second spaced elongated liner edge and parallel thereto, a first zipper slide slidably disposed on and releasably interconnecting said first row of bag zipper teeth and a row of liner teeth of the first pair of spaced rows of liner teeth, a second zipper slide slidably disposed on and releasably interconnecting said second row of bag zipper teeth and a row of liner teeth of the second pair of spaced rows of liner teeth, and a third zipper slide slidably disposed on and releasably interconnecting adjacent rows of liner teeth of said first and second pairs of spaced rows of liner teeth between the rows of liner teeth releasably interconnected to said rows of bag zipper teeth, said zipper assembly releasably securing said bag liner to said sleeping bag.
Apparatus for use in combination with a sleeping bag to contribute to the warmth and comfort of an occupant thereof, the sleeping bag defining a bag interior, a bag head opening, and a bag longitudinal opening extending longitudinally along the sleeping bag and communicating with said bag head opening and said bag interior, said bag longitudinal opening being defined by first and second spaced elongated bag edges, and said sleeping bag including a first row of bag zipper teeth disposed along said first spaced elongated bag edge and a second row of bag zipper teeth disposed along said second spaced elongated bag edge, said apparatus comprising:
- a removable bag liner positionable in the bag interior of a sleeping bag defining a liner interior having a liner head opening and a liner longitudinal opening extending longitudinally along the bag liner and communicating with said liner head opening and said liner interior, said liner longitudinal opening being defined by first and second spaced elongated liner edges;
- and
- a zipper assembly attached to said bag liner, said zipper assembly including first and second pairs of spaced rows of liner zipper teeth, the first pair of spaced rows of liner zipper teeth secured to said first spaced elongated liner edge and parallel thereto and the second pair of spaced rows of liner zipper teeth secured to said second spaced elongated liner edge and parallel thereto, a first zipper slide for releasably interconnecting a first row of bag zipper teeth and a row of liner teeth of the first pair of spaced rows of liner teeth, a second zipper slide for releasably interconnecting a second row of bag zipper teeth and a row of liner teeth of the second pair of spaced rows of liner teeth, and a third zipper slide for releasably interconnecting adjacent rows of liner teeth of said first and second pairs of spaced rows of liner teeth between the rows of liner teeth for releasable interconnection to said rows of bag zipper teeth, said zipper assembly for releasably securing said bag liner to a sleeping bag.
Apparatus for use in combination with a bag to contribute to the warmth and comfort of an occupant thereof, the bag defining a bag interior, a bag head opening, and a bag longitudinal opening extending longitudinally along the bag and communicating with said bag head opening and said bag interior, said bag longitudinal opening being defined by first and second spaced elongated bag edges, and said bag including a first row of bag zipper teeth disposed along said first spaced elongated bag edge and a second row of bag zipper teeth disposed along said second spaced elongated bag edge, said apparatus comprising:
- a removable bag cover positionable about the bag defining a cover interior and having a cover longitudinal opening extending longitudinally along the bag cover, said cover longitudinal opening being defined by first and second spaced elongated cover edges;
- and
- a zipper assembly attached to said bag cover, said zipper assembly including first and second pairs of spaced rows of cover zipper teeth, the first pair of spaced rows of cover zipper teeth secured to said first spaced elongated cover edge and parallel thereto and the second pair of spaced rows of cover zipper teeth secured to said second spaced elongated cover edge and parallel thereto, a first zipper slide for releasably interconnecting a first row of bag zipper teeth and a row of cover teeth of the first pair of spaced rows of cover teeth, a second zipper slide for releasably interconnecting a second row of bag zipper teeth and a row of cover teeth of the second pair of spaced rows of cover teeth, and a third zipper slide for releasably interconnecting adjacent rows of cover teeth of said first and second pairs of spaced rows of cover teeth between the rows of cover teeth for releasably interconnection to said rows of bag zipper teeth, said zipper assembly for releasably securing said bag cover to a bag.
