Sleeping bag having waterproof bottom and side walls and enclosure for a sleeping pad
View Patent ↗A sleeping bag having a waterproof bottom and side wall region. The bottom region extending vertically upward is made from a waterproof material. A cavity formed above the bottom region includes an opening into which may be inserted and removed a sleeping pad. A top region creates a cavity for holding insulative material. A sleeping cavity is provided between the top cavity and the bottom cavity.
1. A sleeping bag having a waterproof bottom and side walls, said sleeping bag comprising:
a top member and a bottom member, each of said top and bottom members having first and second longitudinal edges, said top and bottom members joined together proximate said first and second longitudinal edges, said bottom member comprising a waterproof fabric, wherein said bottom member extends across a bottom region of said sleeping bag and turns upward forming first and second generally vertical sidewall regions of between 1.5 inches to 3 inches prior to being joined together with said top member and wherein said bottom member is configured for being placed on a ground level surface;
a first interior member having first and second longitudinal edges, said first and second longitudinal edges of said first interior member coupled proximate said first and second longitudinal edges of said top and bottom members, said first interior member forming a first cavity between said first interior member and said top member, said first cavity configured for containing an insulative material;
a second interior member having first and second longitudinal edges, said first and second longitudinal edges of said second interior member coupled proximate said first and second longitudinal edges of said top, bottom and first interior members, and forming a second cavity between said second interior member and said bottom member, said second cavity configured for removably containing a sleeping pad, wherein said second interior member includes an opening configured for allowing said sleeping pad to be inserted into and removed from said second cavity; and
wherein a third cavity is formed between said first and second interior members, said third cavity configured for serving as a user sleeping region.
2. The sleeping bag of claim 1 , wherein said insulative material disposed in said first cavity is selected from the group of insulative materials consisting of natural insulative materials and synthetic insulative materials.
3. The sleeping bag of claim 2 , wherein said natural insulative material includes goose down.
4. The sleeping bag of claim 1 , wherein said second interior member is coupled to said first interior member proximate said first and second longitudinal edges of said first interior member.
5. A sleeping bag having a waterproof bottom and side walls, said sleeping bag comprising:
a top member and a bottom member, each of said top and bottom members having first and second longitudinal edges, said top and bottom members joined together proximate said first and second longitudinal edges, said bottom member comprising a waterproof fabric, wherein said bottom member extends across a bottom region of said sleeping bag and turns upward forming first and second generally vertical sidewall regions of between 1.5 inches to 3 inches prior to being joined together with said top member and wherein said bottom member is configured for being placed on a ground level surface;
a first interior member having first and second longitudinal edges, said first and second longitudinal edges of said first interior member coupled proximate said first and second longitudinal edges of said top and bottom members, said first interior member forming a first cavity between said first interior member and said top member, said first cavity configured for containing and insulative material;
a second interior member having first and second longitudinal edges, said first and second longitudinal edges of said second interior member coupled to said first interior member proximate said first and second longitudinal edges of said first interior member and forming a second cavity between said second interior member and said bottom member, said second cavity configured for removably containing a sleeping pad, wherein said second interior member includes an opening configured for allowing said sleeping pad to be inserted into and removed from said second cavity; and
wherein a third cavity is formed between said first and second interior members, said third cavity configured for serving as a user sleeping region.
6. A sleeping bag having a waterproof bottom and side walls, said sleeping bag comprising:
a top member and a bottom member, each of said top and bottom members having first and second longitudinal edges, said top and bottom members joined together proximate said first and second longitudinal edges, said bottom member comprising a waterproof fabric and wherein said bottom member extends across a bottom region of said sleeping bag and turns upward forming first and second generally vertical sidewall regions of between 1.5 inches to 3 inches prior to being joined together with said top member and wherein said bottom member is configured for being placed on a ground level surface;
a first interior member having first and second longitudinal edges, said first and second longitudinal edges of said first interior member coupled proximate said first and second longitudinal edges of said top and bottom members, said first interior member forming a first cavity between said first interior member and said top member, said first cavity configured for containing and insulative material;
a second interior member having first and second longitudinal edges, said first and second longitudinal edges of said second interior member coupled proximate said first and second longitudinal edges of said top, bottom and first interior members, and forming a second cavity between said second interior member and said bottom member, said second cavity configured for removably containing a sleeping pad, wherein said second interior member includes an opening configured for allowing said sleeping pad to be inserted into and removed from said second cavity; and
wherein a third cavity is formed between said first and second interior members, said third cavity configured for serving as a user sleeping region.
