Abstract
A sleeping bag having an elongated bottom mat formed of flexible material and having opposing head and foot edges. The main cover is formed of flexible material, has head and foot edges, and overlies the bottom mat, to which it is permanently secured. The main cover has a transverse slit between the head and foot edges of the cover at a location closer to the foot edge of the main cover than to the head edge, and spaced from the foot edge by about one to three feet. The foot edge of the bottom mat is releasably secured to the foot edge of the main cover, and the head edge of the bottom mat is not joined to the head edge of the main cover to provide an entry into the sleeping bag for a user. A top cover, also formed of flexible material, is secured to the main cover and overlies only the portion of the main cover that includes the foot edge and the transverse slit of the main cover.
Description
- This patent application is a continuation and claims the benefit of U.S. patent application Ser. No. 10/229,083 filed Aug. 28, 2002 for Sleeping Bag, which application is incorporated here by this reference.
- The present invention relates to articles of bedding, and sleeping bags in particular.
- Sleeping bags have long been used by campers either for sleeping outdoors or sleeping in tents. Sleeping bags are also utilized indoors when a bed is not conveniently available.
- A conventional sleeping bag is typically constructed from thermally insulated sheet-like layers of materials, often filled with thermally insulated padding. A typical sleeping bag is constructed of an expanse of a generally rectangular, multi-ply fabric pad folded linearly in half and having interengageable zipper strips extending about the peripheral, unfolded edges where the unfolded edges of the halves of the folded pad meet. In some sleeping bags the padding on one side of the longitudinal fold may be heavier than on the other and may even include padding to serve as a pillow at the top end. The heavier side of the structure then serves as a bottom mat layer. In any event, even when the layers of material are equally padded, one-half of the expanse of the pad serves as a mat to support the occupant's body from beneath, while the other half is folded over the occupant's body to serve as a main cover.
- Conventional sleeping bags are typically constructed so as to keep the occupant warm in chilly, or even very cold, ambient temperatures. Conventional sleeping bags are designed in different weights and with different insulating characteristics depending upon the temperatures of the environments in which they are to be utilized. Nevertheless, virtually all sleeping bags are designed to provide maximum warmth to an occupant for the temperature conditions in which use is contemplated.
- However, quite often a sleeping bag will be utilized in ambient temperatures well above the lowest temperature for which the sleeping bag is designed. Under such circumstances, the occupant often becomes uncomfortably warm when covered by the main covering layer of the sleeping bag. In particular, an occupant's feet and legs may become uncomfortably warm due to retained body heat trapped between the layers.
- While an occupant can always merely throw back the main cover to cool off, this practice is often unacceptable in environments in which sleeping bags are frequently used. Specifically, when the main covering layer of a sleeping bag is thrown off of the occupant's body, the occupant is subjected to attack by flying and crawling insects. Thus, the occupant is faced with the undesirable choices of remaining beneath the main covering layer of the sleeping bag and thus remaining uncomfortably warm, or exposing his or her body to the annoyance, discomfort, and pain of insects.
- A further disadvantage of merely throwing off the covering layer of a conventional sleeping bag is that only the feet and lower legs of the occupant may be uncomfortably warm when encapsulated between the mat layer and the main covering layer of the sleeping bag, while the occupant's upper body may at the same time be quite comfortable. Consequently, if the occupant merely pulls back the top covering layer of the sleeping bag, the occupant's torso may feel chilly, even though the occupant's legs and feet are uncomfortably warm.
- The present invention involves a modification to the construction of an otherwise conventional sleeping bag having a main cover and bottom layers which are permanently secured lengthwise along one side, and secured by a zipper or some other releaseable fastening system along the other side and across the foot extremities of the layers. According to the invention the main covering layer is created with a transverse slit that is wide enough for a person to put his or her legs through. This slit is parallel to the bottom of the sleeping bag and located at about the level of a person's shins. Atop the leg area portion of the sleeping bag a top half length cover is placed and is permanently secured along the sides of the main cover layer. The top cover includes a collapsible mesh end panel extending across an end opening between the top cover and the main cover layer of the sleeping bag. The mesh has a size sufficient to allow air circulation, but is small enough to exclude insects. In addition, another zipper is provided extending transversely across the foot of the sleeping bag to releasably join the main cover layer and the top cover layer disposed on top of the main cover layer together with a zipper slide.
- The user can thus utilize the improved sleeping bag of the invention in at least three different ways. In relatively warm ambient air, the user inserts his or her feet through the slit in the main cover layer and unzips completely the zipper slide on the upper zipper between the main cover layer and the top cover layer located thereabove. The user's feet are then inserted into the area between the main cover layer of the sleeping bag and the top cover layer located above it. The user's feet will then remain relatively cool due to air circulation flowing through the mesh panel that extends between the main cover layer of the sleeping bag and the top cover layer located above it. Alternatively, the user can completely or partially close the opening between the main cover layer of the sleeping bag and the top half length cover layer above it to reduce air circulation into the bag from the outside. In a further manner of use the user withdraws his or her feet from the slit and inserts them beneath the main cover layer and the bottom mat layer of the sleeping bag, thereby utilizing the sleeping bag in a conventional manner.
- In one embodiment of the invention the short or half length top layer can be totally unzipped from the main cover layer so that the sleeping bag becomes a conventional one. Furthermore, the short top layer can be formed of different materials, so that different weight top half length layers can be used interchangeably atop the main cover layer for different weather and climate conditions.
- Construction of a bedding article according to the present invention is not limited to a sleeping bag. Quite to the contrary, the same unique construction may be applied to other articles of bedding, such as blankets. In particular, older people often use double layers of blankets over their feet at night. They sometimes remove the top blanket covering their feet should their feet become excessively warm during the night. However, a blanket constructed according to the present invention may be provided with a main cover layer and a top covering layer over the lower leg portion of the main cover layer. A slit is defined through the main cover layer of the blanket beneath the top covering layer so that the blanket may be utilized in the same manner previously described for a sleeping bag. Thus, a user need not throw off an unwanted blanket from his or her feet during the night, but merely inserts his or her feet through the slit in the main blanket layer so that the feet remain covered by the top layer, and are not excessively warm.
- In one broad aspect the present invention may be considered to be a bedding article for accommodating the body of a person. The bedding article of the invention is comprised of an elongated main cover layer of flexible material having an upper body portion and also a lower body portion with a foot extremity. A transverse slit is defined in the lower body portion between said upper body portion and said foot extremity. A top cover layer overlies the lower body portion of said main cover layer and is secured thereto, either permanently or removably. A person is thereby able to lay beneath the main cover layer with his or her feet covered by both the lower body portion and the top cover layer. Alternatively, the user can insert his or her feet through the slit defined in the lower body portion of the main cover layer so that the feet are covered only by the top cover layer.
- The invention has particular applicability to sleeping bags. In a sleeping bag structure, the bedding article is further comprised of an elongated bottom layer of flexible material underlying the main cover and having an upper body portion with a head extremity and also a lower body portion with a foot extremity. The user lays upon the elongated bottom layer, which serves as a mat, with the main cover layer overlying the body of the user and the top cover layer overlying only the lower body portion of the main cover layer.
- In another aspect the invention may be considered to be a sleeping bag comprising: an elongated bottom mat formed of flexible material and having opposing head and foot extremities; an elongated main cover also formed of flexible material and having head and foot extremities and overlying the bottom mat and permanently secured thereto and having a transverse slit defined therethrough at a location closer to the foot extremity than to the head extremity; and a top cover secured to the main cover and also formed of a flexible material and overlying only a portion of the main cover, including the foot extremity and the transverse slit.
- In preferred embodiments of the invention the layers of flexible material are each formed with opposing longitudinal edges and all of the layers are permanently joined to each other along at least one of the longitudinal edges. Preferably also, the top cover layer has a foot extremity and the bedding article is further comprised of an upper fastening system releasably joining the foot extremity of the top cover layer to the foot extremity of the bottom covering layer. The upper fastening system is typically formed of a pair of transverse strips of interengageable zipper teeth. One strip is attached transversely across the foot extremity of the main cover layer while the other strip is attached transversely across the foot extremity of the top cover layer. A zipper slide is provided for releasably engaging the teeth of the complementary zipper strips together.
- However, alternative fastening systems may also be used. For example, the top cover layer and the main cover layer may be joined to each other by flexible hook and loop fabric fastener strips of the type sold under the registered trademark Velcro®. Also, the foot extremities of the top cover layer and the main cover layer may be joined to each other by snap fasteners. Other conventional fastening systems may also be utilized.
- In some embodiments of the invention the bedding article may be further comprised of a flexible, ventilated mesh panel joined to and extending between the foot extremities of the top cover layer and the main cover layer. Also, when the article of bedding is a sleeping bag, it is further comprised of an elongated bottom mat layer of flexible material underlying the main cover layer and having an upper body portion with a head extremity and a lower body portion with a foot extremity. Preferably, a lower fastening system releasably joins the foot extremities of the main cover layer and the bottom mat layer together. Again, this fastening system may be comprised of a pair of strips of interengageable zipper teeth that are secured and released relative to each other by means of a zipper slide, Velcro® hook and loop fabric fastener strips, or snap fasteners.
- In still another aspect the invention may be considered to be an improvement in a sleeping bag including an elongated, flexible bottom mat with opposing first and second longitudinally engaged portions, an elongated main cover secured to the bottom mat and having opposing first and second longitudinally arranged portions respectively overlying the first and second portions of the bottom mat. According to the improvement of the invention an upper top cover overlies only the second or lower body portions of the main cover and the bottom mat. Also, a transverse slit is defined through and transversely across the second portion of the main cover to accommodate the insertion and removal of the feet of a sleeping bag occupant.

-
FIG. 1 illustrates a sleeping bag indicated generally at 10. The sleepingbag 10 includes an elongated, paddedbottom layer 12 having a firstupper body portion 14 with ahead extremity 16 and a secondlower body portion 18 with afoot extremity 20. Thebottom layer 12 is typically padded with insulating material and forms a mat to support thebody 22 of a user from beneath, as illustrated inFIG. 2 . - The sleeping
bag 10 is further comprised of an elongatedmain cover layer 24 which is also formed of flexible material. Themain cover layer 24 overlies thebottom layer 12 and also has a firstupper body portion 26 with ahead extremity 28 and a secondlower body portion 30 with afoot extremity 32. Atransverse slit 34 is defined through themain cover layer 24 across the width of themain cover layer 24 in thelower body portion 30 between theupper body portion 26 and thefoot extremity 32. Theslit 24 is located between about one foot and about three feet from thefoot extremity 32, typically about eighteen inches therefrom. The sleepingbag 10 is further comprised of a top coverhalf length layer 36 overlying only thelower body portion 30, and not theupper body portion 26 of themain cover layer 24. Thetop cover layer 36 extends longitudinally only about one-half the length of themain cover layer 24 and thebottom mat layer 12. Thetop cover layer 36 has afoot extremity 37 at one end and terminates at about the demarcation between theupper body portion 26 and thelower body portion 30 of themain cover layer 24. - The
layers hand edge 38 and a left-hand edge 40 inFIG. 1 . Thelayers longitudinal edges layers longitudinal edge 40. More specifically, themain cover layer 24 is permanently joined to thebottom mat layer 12 along the leftlongitudinal edge 40, since these two layers are constructed as halves of a large, expansive, thick, rectangular pad folded in half as indicated at 42 to form the left-hand edges 40 of thetop cover layer 24 and thebottom mat layer 12. The transverse edges at thehead extremities bottom layer 12 andmain cover layer 24, respectively, and the transverse edges formed at thefoot extremities bottom layer 12 andmain cover layer 24, respectively, as well as the right side edges 38 of the twolayers zipper strips conventional zipper slide 45. In the embodiment shown, thetop cover layer 36 is permanently joined to themain cover layer 24 along bothlongitudinal edges FIG. 1 . - As best illustrated in
FIG. 1 andFIG. 2 , a ventilated, transversely extending rectangular-shapedmesh panel 48 is provided at thefoot extremity 37 of thetop cover layer 36 and thefoot extremity 32 of themain cover layer 24 and is secured thereto by means of aconventional zipper 50. Thezipper 50 has a pair of zipper strips 52 and 54, respectively attached to thefoot extremity 37 of thetop cover layer 36 and thefoot extremity 32 of themain cover layer 24. The zipper strips 52 and 54 have interengageable zipper teeth that are secured together by means of azipper slide 56. - The
zipper 50 formed by the zipper strips 52 and 54 and theslide 56 serves as an upper fastening system that allows theflexible mesh panel 48 to be opened for ventilation, as illustrated inFIG. 1 andFIG. 2 , or closed to retain body heat, as illustrated inFIG. 3 . The mesh of the ventilatingpanel 48 is fine enough to prevent the entry of insects in between themain cover layer 24 andtop cover layer 36 at the foot extremities thereof when themesh panel 48 is open, as illustrated inFIG. 1 andFIG. 2 . However, the mesh openings are large enough to permit air circulation when thezipper 50 is unzipped, as indicated by thedirectional arrows 58 inFIG. 2 . - As illustrated in
FIG. 1 , the topcover panel layer 36 is provided with elongated, triangular-shapedexpansion panels 60 at both of thelongitudinal side edge expansion panels 60 permit thefoot extremity 37 of thetop cover layer 36 to be lifted and separated several inches from thefoot extremity 32 of themain cover layer 24, thus affording a sufficient area for air to circulate as indicated at 58. - The sleeping 10 of the invention may be utilized in several different ways. As illustrated in
FIG. 1 andFIG. 2 , theuser 22 may lie on thebottom mat layer 12 with themain cover layer 24 pulled up over the user's torso and with the user'sfeet 62 inserted through thetransverse slit 34 in themain cover layer 24 with thezipper 50 unzipped. With the sleepingbag 10 in this condition theupper body portion 26 and the upper part of thelower body portion 30 of themain cover layer 24 above theslit 34 reside atop the body of theuser 22, while the user's lower calves andfeet 62 rest atop the lowermost part of thelower body portion 30 of themain cover layer 24 that resides between theslit 34 and thefoot extremity 32. - The
top cover layer 36 is typically fairly light in weight so that the user'sfeet 62 do not become unduly warm from trapped body heat. Furthermore, since the user's toes typically prop the lower end of thetop cover layer 36 upwardly, pushing it away from the underlying lower portion of themain cover layer 24, thefoot extremities top cover layer 36 andbottom cover layer 24, respectively, are spread vertically apart. This opens up themesh panel 48 to air circulation between the vertically separatedfoot extremities main cover layer 24 andtop cover layer 36, respectively. The user'sfeet 62 are thereby cooled both by the air circulation indicated at 58, and by the single layer, relatively light-weight insulation provided by thetop cover layer 36. - In slightly cooler conditions the user may still wish for his or her lower extremities to be covered only by the
top cover layer 36 but may also wish to eliminate drafts through themesh panel 48, which may be too cool for comfort if ambient temperature falls. In such a situation, the user operates theslide 56 of thezipper 50 to draw the zipper strips 54 and 56 together and interengage their zipper teeth to bring thefoot extremities main cover layer 24 andtop cover layer 36 together, as illustrated inFIG. 3 . With thezipper 50 closed, as illustrated inFIG. 3 , themesh panel 48 is folded inwardly and entrapped within the confines of the sleepingbag 10. The user'sfeet 62 are still covered by only the light layer of insulating material afforded by thetop cover layer 36, but are not subject to the cooling effects of air circulation through themesh panel 48. - In still cooler weather the
user 22 may wish to keep his or herfeet 62 even more fully covered. This may easily be done without undoing any zippers and without getting out of the sleepingbag 10. Quite to the contrary, the user need only withdraw his or herfeet 62 away from thefoot extremities several layers bag 10. The user'sfeet 62 are pulled back out through theslit 34. The user then merely extends his or herfeet 62 back beneath the lowermost portion of thelower body portion 30 of themain cover layer 24. The user'sfeet 62 are then located atop thelowermost portion 18 of thebottom layer 12 and are covered, not only by thetop cover layer 36, but also by themain cover layer 24, as illustrated inFIG. 4 . The user will employ the sleepingbag 10 withfeet 62 inserted as illustrated inFIG. 4 to achieve the maximum conservation of body heat within the foot area of the sleepingbag 10. - Undoubtedly, numerous variations and modifications of the invention will become readily apparent to those familiar with articles of bedding. For example, the same structural combination of the
main cover layer 24 andtop cover layer 36 may utilized in the form of a blanket, completely separable from any underlying structure. Such a blanket may be utilized atop a bed to achieve the same alternative cooling or body heat conservation effects illustrated in the drawing figures. Also, many different types of releaseable fastening systems may be substituted for the zippers shown in the illustrated embodiment. Accordingly, the scope of the invention should not be construed as limited to the specific embodiment depicted and described, but rather is defined in the claims appended hereto. - This invention may be industrially applied to the development, manufacture, and use of articles of bedding, particularly sleeping bags.
