## Background
BACKGROUND OF THE INVENTION
The present invention relates to a diaper changing pad apparatus, in particular a portable diaper changing pad with a memory foam insert. Other aspects of the invention are met through the use of soft, cloth covers.
A number of diaper changing pads are known in the art. However, one common problem in the prior art is the lack of comfort for the baby or infant placed on the changing pad. For example, the changing pad of U.S. Pat. No. 4,886,150 lacks a comfortable surface. Moreover, no known prior art diaper changing pads utilize both a terry cloth cover and a memory foam insert to maximize the comfort of the baby or infant. Thus, there is a need for such a diaper changing pad.
In addition, other prior art changing pads do not incorporate useful features that would improve the versatility and portability of a changing pad. For example, the changing pad of U.S. Patent Pub. No. 2004/0211003 does not incorporate useful accessories such as toys and baby wipes. The changing pads of U.S. Patent Pub. No. 2004/0211003 and U.S. Pat. No. 6,694,552 do not conveniently roll up for easy transportation and storage. Therefore, there is a need for a comfortable diaper changing pad that incorporates such features.

Referring now to the drawings, FIG. 1 shows, generally, a top view of a diaper changing pad that is one example of the present invention. The diaper changing pad comprises a mat having a rectangular middle panel [1] flanked on each side by one of two similar side panels [2], which preferably have a width no more than one half the width of the middle panel [1]. In the preferred embodiment, the middle panel [1] is approximately 10-12 inches wide and approximately 24-28 inches long, which will comfortably accommodate most babies. The middle panel [1], which is preferably made of a soft, comfortable, durable material such as cloth, encloses a body of memory foam [10]. In order to prevent moisture damage to the memory foam [10], the middle panel [1] preferably includes a layer of water-resistant material between the external cloth surface of the middle panel [1] and the body of memory foam [10]. Such water-resistant layer can be a coating applied to the surface of the body of memory foam or a layer connected to the inside surface of the cloth exterior of the middle panel [1].
The middle panel [1] also preferably accommodates a raised head rest section [4] of the memory foam insert, for extra head comfort. The raised head rest may be a raised portion of the memory foam insert [10] or a separate body of memory foam connected to the insert. The raised head rest is described in more detail below in connection with FIG. 3. When changing a baby's diaper, the user preferably places the baby on the middle panel [1], with the baby's head resting on the raised head rest section [4].
The side panels [2] are attached to the middle panel [1] such that they may be folded over the middle panel [1]. Most preferably, the width of the side panels [2] is exactly half of the width of the middle panel [1], so that the outside edges [3] of the side panels [2] meet at the center of the middle panel [1] when the side panels [2] are folded onto the middle panel [1]. The side panels [2], or flaps, are preferably made of thin, comfortable, durable, soft, and sturdy fabric or other material (e.g. terry cloth, fine cotton, or canvas), and may alternatively be lined with a material such as a durable, waterproof plastic.
FIG. 2 shows a bottom view of the same open diaper changing pad. The bottom of the middle panel [1] preferably comprises a slide-proof or nonskid surface area [5] such as a pattern or group of rubber nubs. The bottom edge of the middle panel also preferably comprises an opening [6] for inserting and removing the memory foam insert inside the middle panel [1]. The ability to remove the memory foam insert enables the user to clean or replace the memory foam, if necessary. The opening [6] is preferably closed with snaps, but a flap closure or other closure means such as a zipper, buttons, hook and loop fastener, or other conventional means known in the art could also be employed to keep the memory foam insert inside the middle panel [1]. The bottom of the diaper changing pad also preferably comprises a flap [7] (preferably made of a thin, durable fabric or other material such as cloth, mesh, nylon, or spandex) with snaps [8] or some other closure means to secure the diaper changing pad in the closed, rolled position. In one embodiment, the flap [7] is a short (approximately 2-4 inches) section of durable material that is attached to the bottom surface of the middle panel at the top edge [21] and the side edges [22, 23]. The bottom edge [24] of the flap [7] is not attached to the middle panel.
FIG. 3 shows a memory foam insert [31], which preferably comprises a body of memory foam (or visco-elastic polyurethane foam) which is most preferably 1⁄8-1⁄2 inch thick. The memory foam insert [31] conforms to the shape of the baby or infant's body and reduced the number of pressure points on the infant. The memory foam insert [31] may be made of any type of memory or visco-elastic foam known in the art. In the preferred embodiment, the memory foam insert comprises a raised head rest section [32] which is most preferably raised 1⁄8 inch above the main body of the memory foam insert. The raised head rest section [32] may be formed by the same piece of memory foam as the memory foam insert [31] or may be a separate body of piece of memory foam attached to the main body of the memory foam insert [31]. Preferably, the raised head rest section [32] swells or slopes upward from the main body of the memory foam insert [31] to a height of no more than 1⁄4′′ (most preferably between 1⁄8′′ and 1⁄4′′) above the top surface of the main body of the memory foam insert [31] measured at the middle of the top surface of the raised head rest section [32]. Most preferably, the raised head rest section [32] slopes upward beginning 3 inches from the top and sides of the memory foam insert [31]. In the most preferred embodiment, the raised head rest section [32] is no more than 6 inches in width (from side to side) and 3 inches in length (from top to bottom). Preferably, the memory foam insert [31] is covered with a water-repellant coating [33] to protect the memory foam from moisture and enable the user to easily wipe and clean the memory foam insert. Most preferably, the water-repellant coating [33] covers the entire top surface of the memory foam below 10 inches from the top edge of the memory foam insert.
FIG. 4, FIG. 5, and FIG. 6 show the same diaper changing pad embodiment in various stages of closure. In FIG. 4, the side panels [2] are partially folded toward the middle panel [1]. In FIG. 5, the side panels [2] are completely folded over the middle panel [1] into a folded position. In FIG. 6, the completely folded diaper changing pad of FIG. 5 has been rolled lengthwise and securely closed with a flap [61] (depicted as part [7] in FIG. 2) in a rolled position. With reference to FIG. 2 and FIG. 6, the bottom edge [24] of the flap [7, 61] secures the diaper changing pad in the rolled position by folding the bottom edge [24] of the flap [7, 61] over and around the top edge [21] of the middle panel in the rolled position, in the manner of a folding plastic sandwich bag. Other suitable means for securing the diaper pad in the rolled position include snaps or other closure means such as a zipper, buttons, hook and loop fastener, or other conventional means known in the art. The portable diaper changing pad is rolled in order to preserve the integrity of the memory foam insert and create a compact and portable assembly. The cylindrical rolled diaper changing pad is preferably approximately 10-12 inches long and 2 inches in diameter, to provide for convenient portability. Preferably, the rolled diaper changing pad may be stored and transported in a bag that is sized to hold the changing pad in the rolled position. The bag preferably has pockets for storing accessories, such as toys, baby wipes, pacifiers, food, and other useful articles.
