2. Brief Description of the Related Art
People sometimes encounter a situation where it is desirable to have a clean surface while changing clothing or eating in an area where clean surfaces are not readily available. For example, a person might change clothes while at the beach or camping. Another example is changing a baby's diaper when a changing room or furniture is not readily available. Yet another example situation would be having a picnic. To facilitate clear discussion, the terms dirty and soiled as used herein refer to both exposure to dirt, mud, dust, and the like, as well as being wet. Likewise, the term clean refers to being free from dirt, mud, dust, water, and the like.
Trying to change clothing while maintaining cleanliness poses several problems. First, there is the problem of providing a clean surface in close proximity to the change of clothing and other changing needs. Another problem is containing wet and/or dirty surfaces after changing, so that carrying the surface and other items away does not dirty the user or his or her surroundings, such as the trunk of a car. Still another problem is separating any dirty items from other stored items. Yet another problem is allowing the user to clean up the area and store belongings without getting him or her self dirty. Providing a clean surface and storing soiled items without dirtying one's self or surroundings are problems encountered in other situations besides changing clothing, for example, having a picnic.
Known products have attempted to solve these problems in various ways. For example, the Wet and Dry Gear Bag™ made by Abel Quality Products of Camarillo, Calif., United States, provides a carpet to stand on while changing clothing. However, the carpet cannot be re-folded and stored without touching the dirty surface lying on the ground. The Navigator Wet/Dry bag made by Henri Lloyd, Henri Lloyd North America, Roswell, Ga., United States, provides compartments for wet and dry items. However, this bag does not provide a clean changing area. Further, storage compartments are not easily accessible and require stuffing and rearranging items, which in turn makes it difficult for the user to stay clean while storing items and cleaning up the area.
U.S. Pat. No. 6,212,711 to Gilmour, issued Apr. 10, 2001, describes a change and carry mat made of three layers of material (2, 3, and 6). The mat folds along a fold element 12 and is secured with a fastening element. A portion of the edges (4, 5) are not secured or sealed so that water runs off of wet clothing stored inside the folded mat. While the ability to air wet clothing prevents clothing spoilage, water and dirt can escape from inside the folded mat and dirty the user, the user's car, and other areas exposed to the mat. Further, the user is not protected from any dirt or water remaining on the outside of the mat from lying on the ground.
Although these devices generally function well and provide advantages over prior devices, the devices did not provide users with adequate adaptability, particularly with respect to use in providing clean surfaces or containing dirty surfaces.
A clean carry apparatus provides a clean surface for use and a clean exterior after use. A storage area and base area are connected to a changing area at at least one hinge point. The base area and changing area pivot away from each other at a second hinge point to lay on a surface. The storage area pivots away from the changing area at a hinge point and rests on the base area to expose a clean changing surface. After changing, the storage area pivots back to lay flat across the changing area and contain soiled surfaces within the changing area. By lifting the clean carry apparatus, the base area and changing area pivot together, containing soiled surfaces in contact with the surface. An embodiment provides a privacy shield for changing. Another embodiment provides a foldable mat with a clean area.
Still other objects, features, and attendant advantages of the present invention will become apparent to those skilled in the art from a reading of the following detailed description of embodiments constructed in accordance therewith, taken in conjunction with the accompanying drawings.
The invention of the present application will now be described in more detail with reference to preferred embodiments of the apparatus and method, given only by way of example, and with reference to the accompanying drawings, in which:
Referring to the drawing figures, like reference numerals designate identical or corresponding elements throughout the several figures.
The present invention has been made in view of the above circumstances and provides, among other things, devices for providing a clean surface and containing soiled surfaces. Additional aspects of the invention will be set forth in part in the description which follows and in part will be clear from the description, or may be learned by practice of the invention.

The changing area 1 alternatively includes a covering (not shown). The covering covers the back surface 13 of the changing area. The covering attaches to the back surface 13 of the changing area by a fastening element, such as snaps, clips, magnets, hook-and-loop fastening tape, and the like. The user steps on top of the covering, which can be subsequently removed and thrown away. The covering can be made from disposable materials that are preferably moisture resistant or moisture absorbent so that the covering may simply be discarded after use. Suitable materials include paper, plastic, and Tyvek®D manufactured by DuPont® corporation. Alternatively, the covering can be made from washable materials such as cloth, canvas, sponge, towel material, cotton, waterproof nylon, and the like, so that the covering can be washed and re-used.
The base area 5 attaches to the changing area 1 along the second hinge point 19. The bottom surface of the base area 50 sits against the front surface 11 of the changing area when the clean carry apparatus 10 is folded. The bottom surface 50 can be recessed to form an open area with sides, as illustrated, or can simply be made as a flat panel. A carrying surface 51 is opposite and parallel to the bottom surface of the base area 50. Carrying means 7 is attached to the carrying surface 51. The carrying means 7 aids a person when carrying and lifting the clean carry apparatus 10. As illustrated, the carrying means 7 is a pair of shoulder straps. However, it will be appreciated by one of ordinary skill in the art that a wide variety of devices, such as handles, belts, chest straps, and the like, may be used as a carrying means without departing from the scope of the present invention.
The storage area 3 has a plurality of sides 30, and attaches to the changing area 1 at the first hinge point 17 of the changing area. The inside 33 of the storage area faces the back surface 13 of the changing area when the clean carry apparatus 10 is closed. When the clean carry apparatus 10 is opened, the storage area 3 rests against either the changing area 1 or the base area 5 as needed. This positioning isolates the storage area 3 from the ground or other dirty surfaces during use. The storage area 3 is used to store items a person would access while changing, for example extra clothing and toiletries, as well as any other items the person may want to carry, such as a water bottle, a nutrition bar, or the like, and soiled clothing after changing. The outside 31 of the storage area 3 is opposite of and parallel to the inside 33 of the storage area 3.
The storage area 3 is opened and closed with at least one seal 37. Preferably, the seal 37 is a zipper. However, other sealing devices and arrangements, for example hook-and-loop fastening tape, magnets, snaps, buckles, and the like, may be used without departing from the scope of the present invention. The seal 37 as illustrated is placed on the outside 31 of the storage area 3 such that the user can place or remove items from the closed apparatus 10. Preferably, another seal 39 is placed on the inside 33 such that the user can access the storage area 3 when the apparatus 10 is open (illustrated in
Optionally, a pocket 35 may be added to the storage area 3. As illustrated in
Optionally, a closure means secures the clean carry apparatus 10 in the folded position. Preferably, a first strap 400 with a prong 402 is attached to the storage area 3. A second strap 406 with a receptacle 408 is attached to the base area 5. The first and second straps 400, 406 are of sufficient length to span under the base 5, clean 1, and storage 3 areas. The clean carry apparatus 10 is held closed by fitting the prong 402 into the receptacle. It will be appreciated by one of ordinary skill in the art that a wide variety of closure means, for example, straps, buckles, rings, ties, and combinations thereof, may be used to secure the clean carry apparatus 10 in the closed position without departing from the scope of the present invention.

A sealable flap 508 provides access to the storage area 502. Preferably, the sealable flap 508 uses a zipper to open or close the flap 508. However, it will be appreciated by one of ordinary skill in the art that a wide variety of fasteners, such as snaps, buttons, and the like, may be used without departing from the scope of the present invention. The sealable flap 508 is covered when the mat 600 is in a folded position. Optionally, a second access point (not shown) may be added to the storage area 502 so that the storage area can be easily accessed while the mat 600 is in the folded position. For example, a zipper may be placed on the top side between handles 504 and 506, or another sealable flap can be placed on a side of the bag not covered by the mat 600 in the folded position. As illustrated in
The foldable mat 600 is formed from a first panel 501, second panel 507, and third panel 515. The first panel 501 has a top side 503 and a bottom side 505, and connects to the storage area 502 at a first hinge point 521. The first hinge point 521 extends along the length of the first panel 501 and storage area 502, and allows the first panel 501 to rotate towards and away from the storage area 502. The second panel 507 has a top side 511 and a bottom side 509 and attaches to the first panel at a second hinge point 523. The second hinge point 523 lies adjacent to the bottom sides 505, 509, of the first and second panels, 501, 507, respectively. The third panel 515 has a top side 517 and a bottom side 519 (illustrated in
The clean carry apparatus 500 is carried in a folded position with all panels folded against the storage area 502, in the direction of arrow H in
Once the clean area is exposed, the sealable flap 508 can be opened to access any items kept in the storage area 502. As illustrated in
During use, the clean area provided by the bottom of the third panel 519 and the top of the second panel 511 becomes soiled. However, in the folded position, the soiled areas are contained, and dirt will not contact other surfaces, such as a user's clothing, or the trunk of a car. To return the mat 600 to the folded position, the sealable flap 508 is closed. The third panel 515 is pivoted around the third hinge point 527 until the bottom 519 lies against the top of the second panel 511. Next, the mat 600 is raised with the first panel pivoting about the first hinge point 521 with the top side 503 moving towards the storage area 502, and the second 507 panel pivoting about the second hinge point 523 with the bottom side of the second panel 509 moving towards the bottom side of the first panel 505, until the mat 600 lays against the storage area 502.
Alternatively, the mat 600 can be constructed such that the second hinge point 523 and third hinge point 527 are actually one hinge point. In this embodiment, the first 501, second 511, and third 515 panels join at the one hinge point. The mat 600 operates essentially as previously described, but with the second 511 and third 515 panels pivoting about the one hinge point.
It will be appreciated by one of ordinary skill in the art that the embodiments of the clean carry apparatus of the present invention can be made from a wide variety of materials. Preferable materials are both washable and stain-resistant. Examples include coated nylon, Teflon® fabric, cotton, sponge, towel fabric, antibacterial fabric, i.e., fabric treated with an antibacterial agent such as Microban®, or backed foam fabric.
While the clean carry apparatus 10 illustrated in
While the clean carry apparatus 10, illustrated in accordance with the present invention, includes a carry means 7 that allows a user 100 to carry the apparatus 10 on his back, it will be appreciated by one of ordinary skill in the art that the apparatus 10 may be designed to be carried in a variety of ways, for example, by hand, or over a shoulder, without departing from the scope of the present invention. Likewise, while clean carry apparatus 500 is illustrated with a carry means 504, 506 in the form of a first handle 504 and a second handle 506, it will be appreciated by one of ordinary skill in the art that the apparatus 500 may be designed to be carried in a variety of ways, for example, on the back, or over a shoulder, without departing from the scope of the present invention.
While the invention has been described in detail with reference to preferred embodiments thereof, it will be apparent to one skilled in the art that various changes can be made, and equivalents employed, without departing from the scope of the invention.
