DETAILED DESCRIPTION




Embodiments of the present invention relate to a mat having a collapsible frame. Such a mat can have, for example, a collapsed configuration and an expanded configuration. The mat can be configured so that a body membrane (e.g., a membrane having a terry cloth portion) can be removably attached to the frame. This thereby allows the frame to retain the location and shape of the body membrane while in an expanded configuration. Because the body membrane can be removably attached, the body membrane can be washed without being attached to the frame, and then reattached to the frame for subsequently use. There are many ways to configure the mat and its attachment mechanisms (by which a body membrane can be attached). Many of these possible embodiments are described below.




In one embodiment, a mat includes a frame formed from a flexible, twistable material. The frame is configured to form a closed loop and is movable between a coiled configuration and an uncoiled configuration. A sleeve is configured to receive the frame and to define an opening within at least a portion of the closed loop of the frame. An attachment mechanism is coupled substantially about the periphery of the sleeve. A fabric member is couplable to the sleeve within the opening.




In yet another embodiment, the frame is coupled to an interface membrane(s) to which an attachment mechanism can be coupled. Such an interface membrane(s) can be, for example, one or more portions of fabric attached to the frame and to which the attachment mechanisms can be coupled. The interface membrane(s) need not completely cover or encapsulate the portions of the frame to which the interface membrane(s) are attached. For example, the attachment mechanisms can be strips of fabric each of which has one end glued to the frame and the other end with an attachment mechanism such as a portion of a snap connector, a portion of a hook and pile connection, etc. In such an embodiment, the body membrane can have a complimentary connector so that the body membrane is retained within the opening defined by the frame while the mat is in an expanded configuration.




The term “fabric member” is used here in to include, but is not limited to, a layer of material. For example, the fabric member can be a piece of fabric such as terrycloth or nylon. In one embodiment, the fabric member may include multiple layers of fabric that may or may not be similar materials. In other embodiments, the fabric member can include a non-floatation portion (e.g., a cushion or a raised support structure) or a floatation portion, such as for example, an inflatable bladder, inflatable cushion or inflatable pillow.




Referring to

FIGS. 1

,


2


,


3


and


7


, an embodiment of the collapsible apparatus of the present invention is illustrated.

FIG. 1

illustrates collapsible apparatus


100


in its assembled state in which the fabric member


500


is coupled to sleeve


120


by an attachment mechanism


300


. In the illustrated embodiment, the attachment mechanism


300


is a zipper that is located about a perimeter of opening


200


that is defined by sleeve


120


. Alternatively, the attachment mechanism may be located about an outer perimeter of sleeve


120


or at a location between the outer portion of sleeve


120


and the perimeter of the opening


200


.





FIGS. 2 and 3

illustrate collapsible apparatus


100


in its unassembled state in which the fabric member


500


is removed from the sleeve


120


. When the fabric member


500


is coupled to the sleeve


120


as illustrated in

FIG. 1

, the frame


110


takes a different shape than when the fabric member


500


is removed from sleeve


120


as illustrated in FIG.


3


. More specifically, when the fabric member


500


is removed from sleeve


120


as illustrated in

FIG. 3

, the frame


110


returns to its untensioned, circular configuration and when the fabric member


500


is attached to the sleeve


120


, the frame


110


takes the shape of the fabric member


500


, such as an oval (as shown in FIG.


1


).




Alternatively, the frame


110


may be manufactured from a shape retaining material that allows the frame


110


to maintain its oval configuration regardless of whether the fabric member


500


is coupled to the sleeve


120


. Such a shape retaining material can allow frame


110


to maintain shapes other than circular or oval, such as for example, an oval with squared corners.




The fabric member


500


may include a body member


510


on which a user's body may be positioned during use of the apparatus


100


. The fabric member


500


may also include a pillow membrane


520


for receiving a pillow or similar structure configured to support the head of a user. Alternatively, a pillow or other raised support member may be coupled to, integrally formed with or removably attachable with the fabric member


500


to support a user's head. The body membrane


510


, and the pillow membrane


520


may be, for example, similar materials and may be different than the material used to make the fabric member


500


.




The attachment mechanism


300


includes a first portion


310


that is coupled to the sleeve


120


and a second portion


320


that is coupled the fabric member


500


. The first portion


310


and second portion


320


are, for example, mating fasteners used to retain the position of the fabric member relative to the sleeve


120


. The attachment mechanism


300


can be, for example, zippers and/or other attachment devices such as hook and loop fasteners, buttons, snaps, and/or clips that may be disposed around the periphery of sleeve


120


(or portions of the periphery of sleeve


120


) to retain the position of the fabric member


500


relative to the sleeve


120


.





FIGS. 16 through 20

show an example of a process by which a mat is transformed from an uncoiled configuration to a coiled configuration. Of course, the process can be reversed to illustrate the process of transforming the mat from a coiled configuration to an uncoiled configuration by following

FIGS. 16 through 20

in reverse order.




As shown in

FIG. 16

, a person can hold the edge of the mat


100


at approximately 2 o'clock and 10 o'clock. The mat


100


can be oriented in any manner such as, for example, where its longer side lies across from 3 o'clock to 9 o'clock (as shown in FIG.


16


). As shown in

FIG. 17

, the ends of mat


100


along the longer side can then be folded toward the center, away from the person. As shown in

FIG. 18

, one end of the mat


100


can be further brought towards the center. As shown in

FIG. 19

, the remaining end of mat


100


can then be folded over so that mat


100


is folded into, for example, a substantially circular shape approximately one-nine the area of the mat when in an unfolded configuration, as shown in FIG.


20


.




Referring to

FIGS. 4

,


5


and


6


, another embodiment of the invention is illustrated in which the mat


100


′ includes an interior membrane


150


coupled to sleeve


120


within the opening


200


(i.e., the interior periphery about sleeve


120


). The interior membrane


150


defines a second opening


250


. The attachment mechanism


300


may be located around the perimeter of the opening


250


, for example, located on the interior membrane


150


as illustrated. A fabric member


500


′ is removably couplable to the interior membrane


150


. In the embodiment illustrated in

FIGS. 4 and 6

, a raised support member


540


is located on the fabric member


500


′. Alternatively, the raised support structure may be located on interior membrane


150


such that when the fabric member


500


′ is removed from the interior membrane


150


, the raised support member remains on the interior membrane


150


.




The shape and size of interior membrane


150


can affect the shape that the frame


110


can take when the fabric member


500


′ is removed from interior membrane


150


. For example, where the interior membrane


150


has a relatively small radial width, the frame


110


can return to its original, untensioned configuration (similar to the embodiment illustrated in

FIGS. 1-3

and


7


). Alternatively, where the interior membrane


150


has a sufficiently large radial width, the frame


110


can maintain a shape defined by the tension provided by the interior membrane


150


when the fabric member


500


′ is removed from the interior membrane


150


(as shown in

FIG. 5

where the frame


110


maintains a more oval-like shape).





FIG. 8

illustrates an assembly view of a mat according to another embodiment of the invention. In the illustrated embodiment, the mat


100


″ includes a frame


110


(not shown in

FIG. 8

) retained within a sleeve


120


. The oval-like shape defined by the sleeve


120


is bisected at one end by a dividing element


122


to define two openings


200


″ and


202


. A fabric member


500


″ is separated into a first portion


501


″ and a second portion


502


″, each of which is separately removable from the sleeve


120


. The first portion


501


″ is configured to be removably coupled to the sleeve


120


proximate to opening


200


″ and the second portion


502


″ is configured to be removably coupled to the sleeve


120


proximate to opening


202


. Alternatively, either portion


501


″ or


502


″ may be permanently coupled to the sleeve


120


. A body membrane


510


is disposed on the first portion


501


″ and a pillow membrane


520


or a raised support member


540


may be disposed on the second portion


502


″. The body membrane


510


can be constructed from, for example, a terry cloth material and disposed on the first portion


501


″, which can be constructed from, for example, a nylon material.





FIGS. 9 and 10

show another embodiment of the present invention. In the illustrated embodiment, the mat


700


includes a frame


710


that is formed from a flexible, twistable material. The frame


710


is configured to form a closed loop and is movable between a coiled and an uncoiled configuration. A sleeve


720


is configured to receive at least a portion of the closed loop of the frame


710


. An interior membrane


750


extends from the sleeve


720


and defines an opening


820


. An attachment mechanism


900


is coupled to the interior membrane


750


and is configured to maintain the position of a body membrane (not shown), such as for example a conventional beach towel, with respect to the sleeve


720


. A base member


860


extends substantially across the opening


820


to provide a protective layer between the body membrane that can be placed in the mat


700


and a supporting surface (not shown) upon which the mat


700


is located (e.g., the ground or beach). A pillow or similar raised support member


840


may be coupled to the mat


700


. The body membrane for use with the preset embodiment can include, for example, any flexible membrane such as terrycloth and/or nylon.




Note that attachment mechanism


900


is optional. An alternative embodiment without an attachment mechanism, for example, can retain a body membrane between base member


860


and interior membrane


750


by a frictional fit.




In the illustrated embodiment, the attachment mechanism comprises a plurality of attachment mechanisms (e.g., holes)


900


adjacent the perimeter of the opening. The attachment mechanisms


900


are situated on a pocket


830


that is defined by stitching


880


that surrounds the opening


820


. The pocket


830


may be formed by other means known to those skilled in the art such as hook and loop fasteners, adhesive, etc. Alternatively, the attachment mechanism


900


may include, for example, one or more holes each configured to receive a corner of a towel that is used as a body membrane. Attachment mechanism


900


may also include one or more slits (not shown) that may receive opposite ends of a towel. In yet another alternative embodiment, the attachment mechanism can be a combination of the above-mentioned mechanisms.




In operation, a user places a body membrane (e.g., a towel or the like) within the pocket


830


and passes the corners of the towel up through the attachment mechanisms (e.g., holes)


900


to maintain the towel in position. The ends of the body membrane may then be secured such that they don't pass back through the attachment mechanisms


900


by a variety of methods known to those skilled in the art. For example, the ends of the towel can be retained within attachment mechanisms


900


by a frictional fit. Alternatively, the ends of the body membrane that are passed through the attachment mechanism can be tied in a knot to prevent the body membrane from passing back through the attachment mechanism. Alternatively, a cap or some other securing device may be attached to the body membrane and secured to the attachment mechanisms


900


. Additionally, a grommet may be positioned in the attachment mechanism, for example, to prevent the pocket


830


from being torn.




In yet another alternative, the attachment mechanism can have a portion on interior membrane


750


and another portion on base member


860


. In such an embodiment, the attachment mechanism can be, for example, a snap where the body membrane is snapped between the two portions of the snap. In a similar embodiment, the attachment mechanism can be a pair of hoop connectors of different sizes. In this embodiment, the body membrane can be retained with the pair of hoop connectors by snapping the pair of hoop connectors around body membrane (disposed between the two hoop connectors).




Another embodiment of the present invention is illustrated in FIG.


11


. As shown in

FIG. 11

, the mat


700


′ includes a frame


710


that is formed from a flexible, twistable material. The frame


710


is configured to form a closed loop and is movable between a coiled and an uncoiled configuration. A sleeve


720


is configured to receive at least a portion of the closed loop of the frame


710


. A base member


860


′ extends between opposite sides of the sleeve


720


to provide a protective layer between a body membrane (not shown) that can be placed in the mat


700


′ and a supporting surface upon which the mat


700


′ is located (e.g., the ground or beach). A pillow, or similar raised support member


840


can be coupled to the mat


700


′. An attachment mechanism


900


is coupled to base member


860


′ and is configured to maintain the position of the body membrane (not shown), such as a conventional beach towel, with respect to the sleeve


720


.




In the embodiment illustrated in

FIG. 11

, the attachment mechanism


900


comprises a plurality of openings (e.g., holes) as in the embodiment illustrated in

FIGS. 9 and 10

. In the present embodiment, however, the corners of the body membrane (not shown) are pushed through the attachment mechanism


900


towards (e.g., downward, into the page of

FIG. 11

) the supporting surface upon which the mat


700


′ is located as opposed to being pulled up through the holes by virtue of the position of the holes on the mat


700


′.





FIG. 21

shows another embodiment of the present invention. As shown in

FIG. 21

, the mat


700


′″ includes a frame (not shown) within a sleeve (not shown). The mat


700


′″ includes a pillow or raised support member


840


and attachment mechanisms


900


″. The attachment mechanisms


900


″ can be, for example, straps (e.g., elastic straps) within which a body membrane


500


′″ can be retained within mat


700


′″. Alternatively, the attachment mechanisms can be slots within the mat. In such an embodiment, a body membrane can be pulled down through the slots to retain the body membrane with the mat.





FIG. 22

shows another embodiment of the present invention. As shown in

FIG. 22

, the mat


700


″″ includes a pillow or raised support member


840


and attachment mechanisms


900


′″. The attachment mechanisms


900


′″ can be, for example, straps (e.g., elastic straps) across the mat


700


″″. A body membrane (not shown in

FIG. 22

) can be retained between mat


700


′″ and the attachment mechanisms


900


′″. Although only two such attachment mechanisms


900


′″ are shown in

FIG. 22

, any number of such attachment mechanisms can be included.





FIG. 12

shows yet another embodiment of the present invention. As shown in

FIG. 12

, a mat


700


″ includes a frame


710


that is formed from a flexible, twistable material. The frame


710


is configured to form a closed loop and is movable between a coiled and an uncoiled configuration. A sleeve


720


is configured to receive the frame


710


within at least a portion of the closed loop of the frame


710


. The mat


700


″ further includes an interior membrane


750


″. The interior membrane


750


″ defines an opening


800


across which a body membrane (not shown) may be disposed. A raised support member


840


can be included on sleeve


720


.




An attachment mechanism


900


is located on the interior membrane


750


″ and includes a hole configured to receive at least a portion of a body membrane as described above. The body membrane can be coupled to the attachment mechanism


900


such that the majority of the body membrane is located beneath the mat


700


″ and the corners of the body membrane extend upwardly through the attachment mechanism


900


. Alternatively, the body membrane may be positioned such that the majority of the body membrane is located above the mat


700


″ and the corners of the body membrane extend downwardly through the attachment mechanism


900


.




A method of making mats, for example mat


100


, is described in reference to

FIGS. 13 and 14

. The mat


100


is constructed by first cutting fabric members


500


from a sheet of material (not shown) and then cutting the body membranes


510


from another sheet of material


600


in such a manner that the amount of wasted material from the sheet of material


600


is minimized. After cutting the fabric members


500


and body membranes


510


, a body membrane


510


is attached to each fabric member


500


. The frame


110


is formed from a length of flexible twistable material and is encapsulated, at least in part, by fabric portions that are cut and dimensioned to encapsulate the frame


110


. A fabric portion is stitched around each of the frames


110


such that a sleeve


120


is formed around at least a portion of each frame


110


. An attachment mechanism is positioned about the periphery of the sleeve


120


as described above.




Referring to

FIG. 14

, the body membranes


510


are cut from the sheet of material


600


in such a manner that excess material is reduced. The amount of excess material that results between adjacent body membranes can be less than the amount of material that would result if the body membranes were, for example, oval in shape (as disclosed in, for example, U.S. Pat. No. 6,170,100, entitled “Self-opening Towel,” the disclosure of which is incorporate herein by reference). By cutting the body membranes


510


from the sheet of material


600


and by configuring them so that opposing sides


511


,


512


of adjacent body membranes are nested and substantially equidistant, the amount of waste of material sheet


600


is reduced significantly. Said another way, the sheet of material


600


has a centerline


610


along the length (i.e., the longer side) of the sheet of material


600


; any two adjacent body membranes can be mirror images so that they form interlocking shapes. Such interlocking shapes reduce the amount of excess material of sheet


600


.




The body membranes


510


may be cut from the sheet of material


600


such that at least a portion of sides


511


,


512


of adjacent body membranes


510


are formed by a single cut (e.g., by a punch cut for each body membrane


510


). By minimizing the wasted material from sheet


600


, the overall cost of apparatus


100


is reduced. Mats


100


′ and


100


″ can be constructed in a manner similar to that described in reference to

FIGS. 13 and 14

.





FIG. 15

illustrates an assembly view of the mat


700


. The mat


700


, is constructed by first cutting interior membranes


750


from a sheet of material (not shown) and then by cutting the base member


860


from another sheet of material. The frame


710


(not shown in

FIG. 15

) is formed from a length of flexible twistable material and is encapsulated by fabric portions that are cut and dimensioned to encapsulate at least a portion of the frame


710


. A fabric portion is stitched around each of the frames


710


such that a sleeve


720


is formed around each frame


710


. Openings (or holes) can be formed in the interior membranes


820


to provide an attachment mechanism


900


as described above. Mat


700


is assembled by fastening the interior membrane


750


, the base member


860


and the sleeve


120


. Mat


700


′ can be assembled in a similar manner. Mat


700


″ also can be assembled in a similar manner, but the base member


860


is not included as would be apparent from the above discussion.





FIG. 23

illustrates a top view of a mat according yet another embodiment of the present invention.

FIG. 24

illustrates a side view of the mat shown in FIG.


23


. As shown in

FIGS. 23 and 24

, the mat


1000


includes a fabric member


1020


, a body membrane


1010


and a raised support structure


1040


. In addition, mat


1000


includes a cup holder


1050


within the fabric member


1020


. When the mat


1000


is in an expanded configuration and disposed on a beach for example, the cup holder


1050


can be disposed below the mat


1000


and within the sand of the beach. In alternative embodiments, the cup holder is disposed within other locations within the fabric member, for example, near the raised support structure (see, for example, the mat shown in

FIG. 27

shown below).





FIGS. 32 and 25

through


27


each illustrate a top view of a mat according to yet another embodiment of the present invention.

FIG. 25

shows a mat


1100


having a body membrane


1110


and a raised support structure


1140


.

FIG. 26

shows a mat


1200


having a body membrane


1210


and a raised support structure


1240


.

FIG. 27

shows a mat


1300


having a body membrane


1310


and a raised support structure


1340


. The body membranes


1110


,


1210


and


1310


, and raised support structures


1140


,


1240


and


1340


are examples of alternative shapes. The body membranes


1010


,


1110


,


1210


and


1310


can be made according to the method described above in reference to

FIGS. 13 and 14

. In other words, the shapes of body membranes


1010


,


1110


,


1210


and


1310
