Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority from U.S. Provisional
Application Ser. No. 61/531,651 titled "Outdoor Equipment" which
was filed on Sep. 7, 2011 and claims priority from U.S. Provisional
Patent Application No. 61/454,712 titled "Outdoor Equipment" which
was filed on Mar. 21, 2011, both of which are incorporated fully
herein by reference.
TECHNICAL FIELD
[0002] The present invention relates to outdoor equipment and more
particularly, relates to a spoon or eggplant shaped sleeping
bag.
[0003] Traditional rectangular sleeping bags and more modern mummy
shaped sleeping bags or barrel style sleeping bags are widely used
for both recreational and extreme camping. These bag styles have
suffered from multiple disadvantages. The traditional rectangular
style bags, while roomy and adequate for warmer weather camping,
are generally not useful in colder weather as, owed to wasted
interior volume, they do not adequately conserve body heat.
[0004] Additionally, the rectangular style bags are among the
heaviest of the bag styles. The mummy shaped bags are narrow at the
feet and then taper outward towards the shoulders and then taper
back in around the head. Mummy shaped bags follow the minimum
silhouette of a person lying with legs together and arms held close
to one's chest. This represents the smallest air volume possible
around a person, so mummy shaped bags are best for heat
conservation. The barrel style bags typically maintain a narrow
profile around the entire body. Both styles conserve heat much
better than the rectangular style bags; however they are inherently
constrictive, especially for people who like to be able to move
their legs inside the sleeping bag.
[0005] Accordingly, what is needed is a new design for a sleeping
bag that conserves heat better than a rectangular style bag, but
offers more space around the legs, where it is especially
desired.
SUMMARY OF THE INVENTION
[0006] The present invention features a lightweight sleeping bag
which comprises an upper region that is narrow and configured to be
close to shoulders of a user; a lower region that is wider and
bulbous in shape, allowing for movement around the user's knees and
feet; an opening in the upper region, wherein the opening is
configured to allow sufficient space for the user's head or neck;
and a fastener mechanism expanding a length from the opening of the
upper region to the lower region, wherein the fastener mechanism is
configured to open and close, thereby providing access to an
interior portion.
[0007] It is important to note that the present invention is not
intended to be limited to a system or method which must satisfy one
or more of any stated objects or features of the invention. It is
also important to note that the present invention is not limited to
the preferred, exemplary, or primary embodiment(s) described
herein. Modifications and substitutions by one of ordinary skill in
the art are considered to be within the scope of the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] These and other features and advantages of the present
invention will be better understood by reading the following
detailed description, taken together with the drawings wherein:
[0009] FIG. 1 is a detailed view of the sleeping bag embodiment of
the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] The present invention, shown in FIG. 1, discloses a sleeping
bag 300. The sleeping bag 300 features a spoon shape. The sleeping
bag is narrow at an upper region 302 where shoulders of a user are
positioned. The sleeping bag is wider at a lower region 304 where
knees of a user are positioned. This new sleeping bag design
combines the best features of both a rectangular bag and a mummy or
barrel shaped bag. The sleeping bag 300 is an effective use of
material, and it is designed to pack easily. The shape keeps the
bag close around the shoulders and therefore maintains heat with
less volume to heat up than a rectangular bag. The bag is also less
weight and less volume, which is important for backpacking, than a
rectangular bag. The bag provides more room in the leg region for
better movement and more options for sleep position for a user than
the prior art mummy or barrel shaped bag which has little or no
room around the legs of the user. The bag may feature any other
number of features, such as an opening 306 in the upper region 302
of the bag and a fastener mechanism 308. The fastener mechanism 308
is preferably a zipper, but can also be any other suitable
mechanism, such as hook and loop closure, buttons, snaps, etc. The
fastener mechanism 308 may cover the entire length of the bag or
may cover only a portion of the bag. The fastener mechanism 308
allows for easy opening and closing of the sleeping bag, thereby
allowing a user to enter the bag and close the bag and to open the
bag and exit the bag.
[0011] Modifications and substitutions by one of ordinary skill in
the art are considered to be within the scope of the present
invention, which is not to be limited except by the following
claims.
