Description




BACKGROUND OF THE INVENTION




The present invention generally relates to a towel-mat having a frame member and removably attached membranes.




Conventional beach towels and picnic blankets are typically used, for example, to separate a person from the ground (e.g., beach sand) and/or to line a chair. Difficulty exists, however, in maintaining the shape of these items when being used for such purposes. For example, when a beach towel is used to separate a person from the beach sand, the towel will typically lose its spread out shape and converge towards the person.




Several attempts have been tried to remedy these problems with towels. For example, U.S. Pat. No. 3,862,876, issued to Graves, discloses one attempt to maintain the desired shape of a towel. The towel in Graves has continuous flexible weights secured along two opposed edges of the towel. U.S. Pat. 4,709,430, issued to Nicoll, discloses a beach blanket having a non-metallic tube filled with a liquid weight such as water located at the perimeter of the blanket.




These known towels, however, can be difficult to arrange when configured to have a large size. These towels can be cumbersome to arrange for separating a person from the beach sand, to line a chair, and to pack for removal.




SUMMARY OF THE INVENTION




A towel-mat includes a frame member being formed from a flexible twistable material, a first membrane and a second membrane. The first membrane has a perimeter portion to which a frame member is fixedly attached. The second membrane has a perimeter portion. The second membrane is removably attachable to the first membrane.




In one embodiment, the second membrane is removably attachable to the first membrane along the perimeter portion of the second membrane and along the perimeter portion of the first membrane.




In another embodiment, the perimeter portion of the second membrane includes an extended portion. The extended portion and the perimeter portion of the second membrane forms a perimeter pocket adapted to receive the first membrane.




In yet another embodiment, the towel-mat further comprises a fastener having a first portion and a second portion. The first portion of the fastener is attached to the first membrane, and the second portion of the fastener is attached to the second membrane. The fastener is adapted to removably attach the first membrane to the second membrane.

DETAILED DESCRIPTION




A towel-mat includes a frame member being formed from a flexible twistable material, a first membrane and a second membrane. The first membrane has a perimeter portion to which a frame member is fixedly attached. The second membrane has a perimeter portion. The second membrane is removably attachable to the first membrane.




The term “membrane” is used herein to include, but is not limited to, a layer of material. For example, the membrane can be a piece of fabric such as terry cloth or nylon. In one embodiment, for example, one membrane (e.g., the second membrane which can form a top membrane of the towel-mat) can be a machine-washable fabric such as terry cloth to face the user comfortably; the other membrane (e.g., the first membrane with the frame member fixedly attached which can form a bottom membrane of the towel-mat) can be a fabric, not necessarily machine washable, such as nylon to face the ground.




The term “perimeter portion” is used herein to include an area substantially about the perimeter of a membrane. The perimeter portion can be, for example, twenty percent of the membrane area nearest to the membrane perimeter.




In one embodiment, the perimeter portion of the second membrane includes an extended portion and a facing portion. The extended portion and the facing portion of the second membrane forms a perimeter pocket adapted to receive the first membrane. The term “extended portion” is used herein to include, but is not limited to, a portion of a membrane extending beyond the membrane perimeter. For example, the extended portion can include a portion of the membrane that is folded over at the perimeter. The extended portion can be made of the same material as the membrane itself or can be made of a material different from the membrane, for example, an elastic material sewn to a nylon membrane. The term “facing portion” is used herein to include a portion of a membrane that faces the extended portion of the membrane.




The “perimeter pocket” formed by the extended portion and the facing portion of the membrane can be any type of cavity or opening along at least a portion of the perimeter. In one embodiment, the frame member is fixedly attached along the perimeter of one towel-mat membrane (e.g., the lower membrane) which is, in turn, inserted into the perimeter pocket of another membrane (e.g., the top membrane); the extended portion can be an elastic material which is stretched over the lower membrane so that it is disposed within the perimeter pocket formed by the extended portion and the facing portion of the lower membrane.

FIG. 3

illustrates a bottom view of the top membrane for the towel-mat shown in

FIGS. 1 and 2

.




A towel-mat includes a top membrane


110


and a bottom membrane


120


. A body portion


111


and a head portion


112


can be fixedly attached to top membrane


110


. Body portion


111


and head portion


112


can be fixedly attached to the top membrane


110


by, for example, sewing along the perimeters of those portions. Head portion


112


can be sewn along a portion of the perimeter of the head portion


112


to provide an opening


113


where a pillow can be inserted as will be discussed below.




Top membrane


110


includes an extended portion


114


, which is located on the underside of the top membrane


110


from the top view perspective. Extended portion


114


and the facing portion of top membrane


110


form a pocket into which the bottom membrane


120


can be removably inserted. The extended portion


114


can be made, for example, an elastic material that can be stretched over lower membrane


120


to better place lower membrane


120


within the pocket. In other words, the bottom membrane


120


can be removably attached to the top membrane


110


by placing lower membrane


120


within the pocket formed by extended portion


114


and top membrane


110


.





FIG. 4

shows a bottom or top view of the bottom membrane for attachment to the top membrane shown in

FIGS. 1 through 3

. The lower membrane


120


has the frame member (not shown) fixedly attached. The lower membrane


120


can be folded over the frame member and then sewn along the interior of the lower membrane


120


. In other words, lower membrane


120


can have an oval shape; the frame member can be placed along the perimeter and then the lower membrane


120


can be sewn along the inner perimeter to capture the frame member within the doubled-over lower membrane. Because the frame member is captured within the lower membrane


120


, the frame member is essentially fixedly attached to the lower membrane


120


.





FIG. 5

shows a cross-sectional view of the top membrane shown in

FIG. 1

along line A and the lower membrane inserted into the perimeter pocket of the top membrane. As shown in
