Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to personal covers, and in particular to covers that have multiple purposes.
2. Description of Related Art
Hikers, campers, and other persons engaged in outdoor activities, including attending sporting events, often carry a variety of articles that offer creature comfort or deal with inclement weather. Such people may carry a hooded poncho, sleeping bag, and seat cushion. A collection of these articles is relatively bulky, and the bulk may include a pack or bag to carry these articles.
In U.S. Pat. No. 5,588,749 a large sheet can be removed from a separate carrying case. In one configuration, a separate hood can be attached by a zipper to an edge of the sheet to make a hooded poncho that will be open in the front and therefore, not very weather tight. In another configuration the hood is not used and the sheet is folded in half and closed by a zipper to form a sleeping bag. Unfortunately, this arrangement has three distinct items that can be separated and lost.
In U.S. Pat. No. 5,884,331 a rectangular panel stitched to the edge of a larger rectangular blanket is used as a hood when the larger blanket is draped around a person as a poncho. The blanket has a waterproof outer layer and an inner layer made of cotton or fleece. A pocket located next to the hood panel has an opening for storing the hood and an opposite opening that can be inverted for the purpose of storing the blanket. With this arrangement the poncho must be tied in the front thereby leaving it somewhat exposed to the weather. Also, this blanket is not arranged to be used as a sleeping bag. See, U.S. Pat. No. 5,414,881 for an arrangement having a hood and means for storing the hood. See also U.S. Pat. No. 5,454,125 for a blanket with a pocket that can be inverted for storing the blanket.
See U.S. Pat. No. 4,078,264 for a hooded cape having an integral storage compartment into which the cape can be folded to form a cushion. See also U.S. Pat. No. 2,109,951 for a hooded garment that opens in front and can be folded into a seat cushion. See the following U.S. Pat. Nos. Design: D258,035; D300,784; D305,844; D306,543; D310,149; D312,371; D313,142; D316,791; D322,532; D328,665; D336,986; D341,979; D359,718; and D383,634. See also U. S. Pat. Nos. 3,041,638; 4,188,988; 4,534,065; 4,466,516; 4,597,605; 4,752,971; 5,048,975; 5,103,515; 5,136,738; 5,179,741; 5,346,308; 5,421,045; 5,463,783; 5,481,768; 5,533,653; 5,730,529; and 5,843,556.
Accordingly, there is a need for an article that can be readily converted to offer different utilities, without being bulky, difficult to carry, or composed of distinct parts that are easily separated and lost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 1-5
, a multipurpose article is shown as a planar flexible body
10
having a fabric layer
12
overlaying a waterproof layer
14
. In one embodiment layer
12
is fleece, while waterproof layer
14
is a plastic sheet; although other fabrics and other waterproof sheets may be used instead. Also, in some embodiments a single layer may be used or a fabric layer may be coated with a waterproof material.
The detachable halves
16
and
17
of a zipper (referred to herein as a peripheral fastener) act as complementary linking devices. The zipper half
16
is shown attached to the periphery of body
10
along a portion of edge
10
A and a portion of edge
10
B. The zipper half
17
is shown attached to the periphery of body
10
along a portion of opposite edge
10
C and a portion of edge
10
B. The zipper halves
16
and
17
are both attached to disjoint portions of common edge
10
B, on opposite sides of a central fold line
18
that runs lengthwise.
As shown in
FIG. 2
, flexible body
10
has been folded along fold line
18
to bring edges
10
A and
10
C together thereby allowing zipper halves
16
and
17
to mate, in order to form a sleeping bag that can be closed by the zipper, except along edge
10
D. The overall dimensions of flexible body
10
and therefore the size of the sleeping bag of
FIG. 2
can be varied depending upon the expected size of the user, the desired amount of space, etc.
A pouch
20
is shown attached to flexible body
10
to straddle fold line
18
.
FIGS. 5A and 5B
show pouch
20
formed of a layer
20
A overlying an inner layer
20
B. Preferably, layers
20
A and
20
B are made of a fleece fabric and sheet plastic, respectively, although different materials can be used in other embodiments.
A carrying handle is sandwiched between overlapping edges of layers
20
A and
20
B, which are stitched together. All of the overlapping edges of layers
20
A and
20
B are stitched together except for the edges opposite handle
22
. Accordingly, the resulting opening between layers
20
A and
20
B forms an auxiliary pocket
24
. Pouch
20
is attached to body
10
so that (a) all edges of layer
20
B are stitched to body
10
, except for the edge carrying handle
22
; and (b) all edges of layer
20
A are stitched to body
10
, except for the edge opposite handle
22
. Consequently, pouch
20
provides previously mentioned auxiliary pocket
24
and a main pocket
26
. Main pocket
26
provides an opening between pouch
20
and flexible body
10
at the end carrying handle
22
. Pockets
26
and
24
are herein referred to as a first one and a second one, respectively, of a pair of layered pockets.
An opening
28
is formed in flexible body
10
by cutting a slit
30
in layer
12
and a slit
32
to in layer
14
. Slits
32
and
32
are made adjacent and parallel to the edge of pouch
20
opposite handle
22
. A closure device is shown herein as a complementary pair of hook and loop fasteners
34
and
36
. Fasteners
34
and
36
are stitched to opposite faces of flexible body
10
on opposite sides of the opening
28
formed by slits
30
and
32
. Specifically, fastener
34
is placed on layer
12
between slit
30
in pouch
20
and stitched to both layers
12
and
14
. Fastener
36
is placed on layer
14
on the side of slit
30
opposite pouch
20
and stitched to layers
12
and
14
. Accordingly, fasteners
34
and
36
can reach each other through opening
28
in order to mate.
In more developed embodiments, the slits
30
and
32
will be appropriately reinforced. For example, a binding strip may be placed as a loop in opening
28
, folded back on either side of flexible body
10
, and stitched in place to form a binding. This binding may be elaborated and may have a separate component extending from opening
28
to form a short collar having Velcro™ fasteners on opposing faces.
A hood
38
may be a double layered body made of the same components as layers
12
and
14
. The external layer may be sheet plastic while the internal layer may be a fleece fabric (although the foregoing is reversed in
FIGS. 3
,
4
,
5
A, and
5
B where the hood is shown inside out). A face opening
40
is encircled by a hemmed-in drawstring
42
that can restrict opening
40
. The lower border
44
of hood
38
is stitched contiguously around opening
28
.
To facilitate an understanding of the principles associated with the foregoing article of
FIGS. 1-5B
, its operation will be briefly described, with reference to the methods illustrated in
FIGS. 6A-6D
,
7
, and
8
. The article may be used as a sleeping bag by folding flexible body
10
along fold line
18
(
FIG. 1
) to bring zipper halves
16
and
17
together as shown in FIG.
2
. The zipper halves
16
and
17
may then be fastened in the usual manner to provide a sleeping bag that is essentially closed on all sides except along edge
10
D. The zipper is shown partially opened along edges
10
A and
10
C to allow the user a little more ventilation and freedom of movement. The zipper can be more fully opened when the user wishes to exit the sleeping bag.
The article may be folded and converted into a seating cushion by following the steps shown in
FIGS. 6A-6D
. Reference should also be made to
FIG. 1
where fold lines F
1
, F
2
, F
3
and F
4
and edges
10
A and
10
C constitute equidistant lines dividing flexible body
10
into five equal columns. Similarly, fold lines F
5
, F
6
, and F
7
and edges
10
B and
10
D constitute equidistant lines dividing flexible body
10
into four equal rows. Consequently, the surface a flexible body
10
is thereby divided into a 5×4 matrix or checkerboard, although other arrangements are contemplated.
It will be noted that each of these cells of the matrix are squares having about the same dimension as pouch
20
. Also, fold line
18
is equidistant between fold lines F
2
and F
3
and equidistant between edges
10
A and
10
C. The edge of pouch
20
opposite handle
22
is contiguous with fold line F
6
. In fact, the four edges of pouch
20
are contiguous with fold lines F
2
, F
3
, F
6
, and F
7
.
In a first longitudinal fold, flexible body
10
may be folded along fold line F
2
(
FIG. 1
) lengthwise. This is performed by placing flexible panel
10
with the pouch
20
down, lifting edge
10
A, and placing (a) edge
10
A approximately at fold line F
4
, and (b) fold line F
1
approximately at fold line F
3
.
In a second longitudinal fold, edge
10
C is lifted (thereby lifting edge
10
A) and simultaneously folding along fold lines F
3
and F
1
. In a third longitudinal fold, edge
10
C is again lifted and folded on fold line F
4
.
The outcome of this folding process can be further understood by reviewing folded edge
10
B as shown in FIG.
6
A. This Figure shows that the folded package has a width that is about the same as the width of pouch
20
. It will be understood that many other folding schemes are possible but it is desirable that the chosen folding scheme result in a package that has the same width as pouch
20
and leaves pouch
20
exposed.
The folded package of
FIG. 6A
is shown being further folded in half, width-wise, along fold line F
6
(fold line F
6
also shown in
FIG. 1
) by lifting edge
10
D. Since the package had an overall length about four times the length of pouch
20
, after folding the package will have a length twice that of pouch
20
, as shown in
FIG. 6B. A
final, width-wise fold along fold lines F
5
and F
7
(fold lines also shown in
FIG. 1
) is illustrated by the transition from
FIG. 6B
to FIG.
6
C.
This completed package has approximately the same length and width as pouch
20
and leaves pouch
20
exposed. Again, many other folding schemes are possible, but it is desirable that the chosen folding scheme result in a package that has the same length and width as pouch
20
and leaves pouch
20
exposed. While compact folding procedures are preferred, flexible body
10
can even be gathered together behind pouch
20
in a random, crumpled bunch.
Assuming for now the configuration shown in
FIG. 6C
, this package will unfold if one attempts to carry it using handle
22
. Therefore, the user now ought to invert pocket
26
of pouch
20
so that the folds of flexible body
10
are captured inside the pocket as shown in FIG.
6
D. The resulting package can be conveniently carried using handle
22
without unfolding. Also, the package can be used as a seat cushion, for example, when the user is seated outdoors at a sporting event.
In the event of rain or inclement weather, the user may reverse the previous inversion of pouch
20
(
FIG. 6D
) and unfold the flexible body
10
back to the configuration shown in FIG.
1
. The user may now reach into the auxiliary pocket
24
(
FIG. 4
) and pull out hood
38
. The user will then unfasten the hook and loop fasteners
34
and
36
(
FIGS. 3 and 5A
) to open the opening
28
in order to achieve the interim condition shown in
FIGS. 3 and 7
. Next, the user will push hood
38
through opening
28
so that the hood extends from the waterproof side of flexible body
10
. Also, the hood will be inverted to expose its waterproof side.
The flexible body
10
now be placed over a user's shoulders, with the user's head passing through opening
28
as shown in FIG.
8
. Accordingly, flexible body
10
and hood
38
act as a hooded poncho. Significantly, the hood
38
is centered on the flexible body
10
. Thus, the article is closed in front and drapes by the same amount in both the front and back.
When this poncho is no longer needed, the user can remove the article and push hood
38
back through opening
28
before resealing fasteners
34
and
36
. Hood
38
can then be stuffed back into auxiliary pocket
24
as shown in FIG.
4
. This returns the article to the condition shown in FIG.
1
. As described before, the article can either be converted to the sleeping bag of
FIG. 2
or the compact package of FIG.
6
D.
It is appreciated that various modifications may be implemented with respect to the above described, preferred embodiment. While the flexible body is shown with double layers, in other embodiments a different number of layers or single layer may be employed. As an example, an insulating material may be placed between two outside layers. Also, the illustrated fasteners can be replaced with a variety of zippers, snaps, hook and loop fasteners, buckles, laces, catches, etc. Also in some embodiments, the hood may be eliminated or made removable by employing releasable fasteners. Similarly, the auxiliary pocket for storing the hood can be eliminated in some embodiments. Also the carrying handle can take a variety of forms, may be removable, or may be eliminated altogether. Furthermore, in some embodiments the pouch may be placed next to a different portion of the opening, or in some cases, may be spaced from the opening. Moreover, the various dimensions and shapes can be altered depending upon the desired capacity, size, or other design considerations.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
