Claims
Having thus described this invention, what is asserted as new
is:
1. In combination:
A sleeping bag;
A partially detached flexible inflatable cover for said bag, the
cover forming a tent with the bag disposed therein and when
inflated defining a horizontal hollow half cylinder closed at each
end with the flat side of the half cylinder serving as the bottom
of the tent, the bottom the bag being secured to the inner surface
of the flat side, at least one of the closed ends containing
sealable flaps which can be opened to function as a door; and
flexible loops secured to the cover and extending outside of the
cylinder, said loops being arranged to receive stakes which when
driven into the ground hold the tent in place.
Description
SUMMARY OF THE INVENTION
My invention is directed toward a new type of apparatus
particularly useful in camping and similar field activities.
Campers and others conventionally carry sleeping bags and
collapsible tents as separate items.
I have succeeded in combining these items into one light weight
collapsible package which can be readily erected when and as
desired quickly and easily and which can be collapsed and rolled
into the original package just as quickly and easily.
To this end, the bag is provided with a partially detached flexible
inflatable cover. When not in use, the bag and cover can be rolled
up into a conventional cylindrically shaped roll which is easily
carried or stored.
The cover, when the package is unrolled, can be inflated to form a
tent with the bag disposed therein ready for use. More
particularly, the inflated cover defines a hollow half cylinder
closed at each end with the flat side of the cylinder serving as
the bottom of the tent. The bottom of the bag can be secured to the
inner surface of the flat side. At least one of the closed ends can
contain sealable flaps which can be opened to function as a door.
the cover can have flexible loops which extend outside of the
cylinder and which can receive stakes. The stakes, when driven
through the loops into the ground, can hold the tent in place.
Alternatively the tent can be held in place without stakes by the
weight of the contents.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a perspective view of my invention in use;
FIG. 2 is a cross section taken along line 2--2 in FIG. 1; and
FIG. 3 is a perspective view of my invention in rolled up or
collapsed position.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to FIGS. 1-3, a flexible roll up type sleeping bag 10
has a hollow roll up type cover 12 with ribs 14. The cover is
hollow and has an inflation valve 16 which can be removed to allow
air to escape. The valve when in position is one way and only
permits the cover to be inflated.
The cover is partially detached from the bag having a non
inflatable section 18 which is secured to the bottom of the
bag.
The cover when inflated forms a horizontally extending hollow half
cylinder with closed ends 20. At least one end has sealable flaps
22 which can be opened to function as a door. Section 18 forms the
bottom of the tent and supports the bag for use.
Flexible loops 24 are secured to opposite sides of section 18 and
can be extended outward therefrom to receive stakes 26. When the
stakes are driven therethrough, the tent can be held in place for
use as indicated.
The inflatable portion of the cover can have sealed port holes 28
and sealable vents 30.
While I have described my invention with particular reference to
the drawings, such is not to be considered as limiting its actual
scope.
