Patent Application
20220151408
The present invention relates to sleeping bags, and more particularly to “mummy” type sleeping bags.
Sleeping bags provide a comfortable enclosure to keep the user warm while sleeping. With mummy type sleeping bags, the shape of the bag is generally a gradual taper that conforms more closely with the user's torso and legs than the conventional rectangular sleeping bag. With rectangular and mummy type sleeping bags, the fabric panels forming the bag are not resilient and can be confining. The closer fit of the mummy type bag can be more confining or constricting for some users, particularly when repositioning themselves to attain a comfortable sleep position.
As can be seen, there is a need for improved sleeping bag that is less constricting and provides mobility to the user while contained within the bag.
In one aspect of the present invention, a sleeping bag is disclosed. The sleeping bag includes a top panel and a bottom panel formed as substantially mirrored halves generally conforming to a body shape of a user. An elastic gusset is interposed between and joined with a peripheral side edge of each of the top panel and the bottom panel, defining an interior chamber for containing the user.
In some embodiments, the top panel, the bottom panel, and the elastic gusset define a hood area to cover a user's head area.
In some embodiments, top panel, the bottom panel, and the elastic gusset are formed as a plurality of layers defining a containment area adapted to contain an insulating fill.
In some embodiments, a quilted stitching contains the insulating fill in a dispersed relation within the containment area.
In some embodiments, a zipper is attached along the peripheral side edge of the top panel to releasably join the top panel with the elastic gusset. The zipper is operable by to selectively open and close the interior chamber to allow the user to ingress and egress the sleeping bag.
In some embodiments, a drawstring is carried within a sleeve defined laterally across an upper aspect of the top panel. A drawstring pull is operable to cinch the drawstring and draw the upper ends of the top panel about the user's body.
In some embodiments, a hood is integrally formed with the sleeping bag and the drawstring is operable to draw the hood about the user's head.
In some embodiments, a pillow is integrally formed with the interior chamber.
In some embodiments, one or more pockets are defined within the interior chamber.
In other embodiments, one or more of the top panel and the bottom panel are formed of an elastic material.
In yet other embodiments, a height of the elastic gusset is selected to define the interior chamber according to a body size of the user.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description, and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention.
Broadly, embodiments of the present invention provide an elastic gusset sleeping bag that is less constricting and provides mobility to a user contained within the sleeping bag.
As seen in reference to the drawings of
The height of the elastic gusset 16b may be varied to size the interior chamber to accommodate for differing body sizes of the users, small, medium, large, etc. This configuration also provides efficient manufacture of the elastic gusset sleeping bag 10 by permitting utilization of a single top panel 16a and bottom panel 16b and still accommodate for the differing body sizes.
Each of the top panel 16a, the side panel 16c, and the gusset 16b are formed as a plurality of layers defining a containment area 16d adapted to contain an insulating fill, such as down, Dacron, or the like. The plurality of layers of the top panel 16a and the bottom panel 16c may include a quilted stitching to contain the insulating fill in a dispersed relation within the containment area 16d.
A zipper 12 may extend along the peripheral side edge of the top panel 16a to releasably join the top panel 16a with the elastic gusset 16b. The zipper 12 is operable by a zipper slide 12a to selectively open and close the elastic gusset sleeping bag 10 to allow the user to ingress and egress the elastic gusset sleeping bag 10 or to allow for ventilation of the interior volume of the elastic gusset sleeping bag 10.
In some embodiments a drawstring 20 is carried within a sleeve defined laterally across an upper aspect of the top panel 16a. A drawstring pull 22 is utilized to cinch the drawstring 20 and draw the upper ends of the top panel about the user's body 24. In embodiments with the hood 17, the drawstring 20 may be incorporated in like manner with the hood 17 to permit the user to draw the hood 17 about the user's face. In some embodiments, the interior of the elastic gusset sleeping bag 10 may be provisioned with an integral pillow element 14 to support the user's head. In yet other embodiments, one or more pockets 18 may be provided within the interior chamber, such as on an inner surface of the top panel 16a. The elastic gusset sleeping bag 10 may be conveniently carried within a travel bag 26.
The claimed invention differs from what currently exists. the elastic gusset sleeping bag 10 utilizes a unique elastic gusset 16b on the sides top and bottom of the sleeping bag to provide expansion and stretch of the body of the elastic gusset sleeping bag 10 responsive to a user's 24 movements within the interior chamber of the elastic gusset sleeping bag 10.
In some embodiments, one or more of the top panel 16a and the bottom panel 16 may be formed of an elastic material like the gusset 16b to provide even greater freedom of movement within the elastic gusset sleeping bag 10. The elastic gusset sleeping bag 10 solves the problem of mobility in sleeping bags. The elastic gusset sleeping bag 10 adds freedom of movement when sleeping rotating, moving your arms legs, head, back and sides.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
