DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now in more detail to the drawings, the invention will now be more fully described.
Referring now to FIG. 1, the diaper changing station is shown generally as 10. A cutaway of the invention during use is shown. The diaper changing station provides a collapsible enclosure (more clearly shown in FIG. 2) that allows a caregiver 1, to change the diaper of an infant 2, while having some privacy to do so. The invention includes an internal collapsible frame 12 that is enclosed in a flexible fabric cover 14. In one embodiment, the flexible fabric is sewn around internal collapsible frame as shown. In alternate embodiments, the cover can enclose internal frame 12 by any fastener such as snaps, zippers or Velcro®.
Referring now to FIGS. 2-4, frame 12 includes a front frame generally shown as 16, a rear frame generally shown as 18 and two collapsible side frames generally shown as 20 and 22 interconnecting the front frame and the rear frame. Frame 12 is formed of a plurality of flexible frame rods, generally shown as 24, interconnected by hinged clips. In one embodiment, the frame 12 is formed of four different sized rods shown as 24a, 24b, 24c and 24d. In at least one embodiment, flexible rods 24 are made of fiberglass and the hinged clips are friction clips that hold flexible rods in position by a friction grip. The friction grip clips act as a safety clips for preventing the internal, collapsible frame 12 from unintentional collapse without human interaction. In at least one alternate embodiment, one or more of the hinged clips could include an additional safety mechanism such as a detent lock for providing a locked position such as when the frame is in an erect position so as to prevent the hinges in the hinged clips from operating and thus preventing the framing rods from pivoting about the hinge when the safety clip is in a locked condition. To allow the hinged nature of the hinged clips to be used, the safety clips must be placed in an unlocked condition such as by pressing a button on the clip thus allowing the rods to pivot about the hinge.
Front frame 16 has a generally arched shaped consisting of a base 16a and a domed top 16b interconnected by two sides 16c and 16d. To provide a point of reference, the X axis will be defined as extending along the width of the frame, the Y axis as extending from the base to the domed portion and the Z axis extending from the front frame to the rear frame. The base 16a includes a framing rod 24a that interconnects two three-way clips 26a and 26b that allow flexible framing rods 24a, 24b and 24d to extend from the three-way clip along the X, Y, and Z axis, where the framing rod 24d extending along the Z axis is hingedly connected to the three-way clip. Framing rod 24a extends along the X axis to interconnect three-way clips 26a and 26b. The side of front frame 16 are formed by two opposing framing rods 24b that extend along the Y axis connecting each of the three way clips 26a and 26b to a three-way “T” clip 28a and 28b that allow framing rods 24b, 24c and 24d to extend along the Y and Z axis, where the framing rod 24d extending along the Z axis is hingedly connected to the three-way clip. The domed top 16b is formed by a fourth framing rod 24c that interconnects the three-way “T” clips 28a and 28b by extending between the “T” clips in an arched fashion, thus creating a domed top.
Much like the front frame, the base 18a of rear frame 18 is formed by framing rod 24a which interconnects two three-way clips 26c and 26d that are substantially identical to the clips represented by 26a and 26b. The sides 18c and 18d are formed by framing rods 24b that extend along the Y axis from each of the three-way clips 26c and 26d, interconnecting each of the three-way clips with a four-way clip 30a and 30b that allows framing rods 24a, 24b, 24c and 24d to extend from the clip along the X, Y and Z axis, where the framing rod 24d extending along the Z axis is hingedly connected to the four-way clip. Much like front frame 16, the domed top 18b of rear frame 18 is formed by a framing rod 24c which interconnects four-way clips 30a and 30b and extends between them in an arched fashion. Four-way clips 30a and 30b are also interconnected by a fifth framing rod 24a which extends between the four-way clips in parallel relation to the framing rod 24a that forms the base 18a of the rear frame 18.
While front frame 16 and rear frame 18 have been described as being formed by several framing rods 24a, 24b and 24c, both the front and rear frame could be formed by one pre-formed framing rod. In such an embodiment, the need for the three-way clips 26a, 26b, 26c, 26d, 28a, 28b, and four-way clips 30a and 30b would be alleviated and such clips could be replaced with a clip that allows the framing rods 24d that form a portion of the side frames 20 and 22 to be hingedly connected to the front and rear frames so that when in an erect position, the side frames interconnect front frame 16 and rear frame 18 by extending along the Z axis. When in a collapsed position, however, the hinged connection would allow the framing rods to extend along or generally parallel to the X axis.
Referring now to FIGS. 3 and 4, collapsible side frames 20 and 22 can be more clearly seen. The side frames interconnect front frame 16 and rear frame 18 and are collapsible. Side frames 20 and 22 include opposing upper rails 20a and 22a and opposing lower rails 20b and 22b. In at least one embodiment, each upper rail is formed by four framing rods 24d interconnected by hinged clips 32a, 32b, 32c, 32d, 28c and 28d. Upper rails 20a and 22a are hingedly connected to front frame 16 via three way “T” clips 28a and 28b, each of which includes one hinge along the Z axis. On each upper rail 22a and 20a, framing rod 24d extends from the “T” clip, and connects each “T” clip 28a and 28b to a set of two-way linear dual-hinged clips 32a and 32d. The dual-hinged nature of the two-way linear clip allows both framing rods that are hingedly interconnected by the clip to pivot between the X axis and the Z axis. Two-way clips 32a and 32b are connected to a set of three-way dual-hinged “T” clips 28c and 28d by a framing rod 24d. These dual-hinged “T” clips allow the framing rods 24d that form the upper rails 20a and 22a of the collapsible side frames to pivot between the X axis and the Z axis. The “T” clips 28c and 28d are interconnected by another framing rod 24d to another set of two-way linear dual-hinged clips 32c and 32d, which in turn are interconnected to the rear frame by a set of framing rods 24d that are hingedly connected to the rear frame via the four-way clips 30a and 30b. 
Much like upper rails 20a and 22a, lower rails 20b and 22b interconnect front frame 16 and rear frame 18 and in at least one embodiment, are formed by four framing rods 24d interconnected by hinged clips 32e, 32f, 32g, 32h, 28e and 28f. Much like upper rails 20a and 22a, lower rails 20b and 22b are formed by a first set of framing rods 24d which interconnect the hinged “T” clips 26a and 26b of the front frame 16 to a set of two-way dual-hinged clips 32e and 32f, which are connected to a set of dual-hinged “T” clips 28e and 28f by a second set of framing rods 24d. The “T” clips are interconnected, by a set of framing rods, with a second set of two-way dual-hinged clips 32c and 32d, which are connected to the hinged three-way clips 26c and 26d of the rear frame via a set of framing rods 24d that are hingedly connected to the three-way clips 26c and 26d. 
In at least one embodiment, the opposing upper rails 20a and 22a are interconnected by a framing rod 24a that extends in a generally perpendicular relation to the upper rails 20a and 22a to provide increased structural integrity. Similarly, the opposing lower rails 20b and 22b are interconnected by a framing rod 24a that extends in a generally perpendicular relation to the lower rails. The framing rod connecting the opposing lower rails is covered by the flexible fabric cover 14 and padding 15 contained within the flexible fabric cover so that the framing rod is out of sight and out of the way. While the friction fitting of the clips and the locking safety mechanism alleviate the need for increased structural integrity, the framing rod connecting the upper rails 20a and 22a extends through the interior of the diaper changing station providing extra stability as well as a means for hanging objects such as a mobile, towel, diaper, or any other object that may be hung over framing rod.
In alternate embodiments, however, the framing rod interconnecting collapsible side frames are not included. In such embodiments, the friction fit safety clips and/or the locking safety clips allowing the hinged nature of the “T” clips 28c, 28d, 28e, and 28f to be utilized only after the safety clip is placed in an unlocked condition alleviate the need for the framing rod interconnecting the opposing upper rails 20a and 22a. When in an erect position, safety clips 28c and 28d are placed in a locked condition so that the framing rods interconnected by the safety clips may not pivot about the hinge of the “T” clips 28c and 28d until the safety clips are placed in an unlocked condition, thus allowing the framing rods to pivot about the hinge and the frame to collapse.
While the collapsible side frames 20 and 22 have been generally described as having opposing upper rails 20a and 22a and opposing lower rails 20b and 22b, in alternate embodiments, collapsible side frames are formed by a single set of opposing side rails. In another embodiment, collapsible side rails 20 and 22 could be formed by opposing upper rails 20a and 22a and opposing lower rails 20b and 22b that consist of two framing rods interconnected by dual-hinged “T” clips 28c and 28d, thus alleviating the need for the additional dual-hinged clips 32a, 32b, 32c, and 32d. In another embodiment, more than four framing rods could be interconnected by the hinged clips, depending on the desired length of the framing rods or the internal frame itself.
Referring now to FIG. 2, the internal, collapsible frame 12 is enclosed in a flexible fabric cover 14. In one embodiment, the fabric cover provides a barrier to UV rays to prevent the infant from becoming burnt and is resistant to liquids. The fabric cover is also fire resistant. One such fabric cover is polyester. The base 34 of the diaper changing station includes padding 36 enclosed by flexible fabric cover 14 for providing support and comfort to the infant using the invention.
The diaper changing station includes at least one pocket 38 for storing objects such as diapers, cloths, pacifiers or any other desired object. In one embodiment, two pockets are disposed on an interior surface of the side walls of the invention. However, in alternate embodiments any number of pockets could be included which could be disposed on an interior or exterior surface of either side walls or rear wall of the diaper changing station.
The diaper changing station further includes a plurality of vents 40 and 42, for allowing fresh air to circulate throughout the changing station. In at least one embodiment, the vents are made of a mesh fabric allowing air to circulate while keeping bugs or debris from entering the diaper changing station. In alternate embodiments, the vents could be formed by an opening in the fabric 14. Each vent includes an adjustable cover 44 for allowing the vent to be partially or completely obstructed. In one embodiment, the adjustable cover comprises a piece of flexible fabric that is attached to the bottom of the vent and includes several fasteners that allow the cover to be fastened at various vertical points along the height of the vent for partially or completely obstructing the vent. While the shown embodiment includes two vents, alternate embodiments allow for any number of vents desired. In the shown embodiment, the fasteners 46 for securing the cover 44 to the vent 40 are snaps. In alternate embodiments, however, any fastener that would allow the cover to be secured to the vent may be used.
In at least one embodiment, the diaper changing station has a height of twenty-four inches, which is measured from the base to the top of the domed roof; a width of twenty-two inches, which is measured from the left side frame to the right side fame; and a length of twenty-five inches, which is measured from the front frame to the rear frame. To provide an adjustable length, a flexible extension 48 is provided. The extension is disposed at the open front and has a width substantially identical to the width of the diaper changing station and extends outwardly eight inches. In one embodiment, the extension folds under or over the base 34 or may be secured via fasteners 49 to the fabric cover 14 supported by front frame 16 to create a small gate-like barrier to the open front. In at least one embodiment, the extension has a shape that is generally consistent with or similar to that of the front frame. In such an embodiment, when in a closed position, so that fasteners 49 secure extension 48 to front frame 16, a closure is provided for completely obstructing the open front created by flexible fabric cover 14 and internal frame 12.
In one embodiment, the diaper changing station is provided with a handle 50 for allowing easy movement or transportation of the invention. While the shown embodiment illustrates the handle 50 being disposed on the domed top of the diaper changing station, the handle could be disposed on any exterior surface of the invention. Further, the handle could be adjustably securable having one end disposed on the arched top of either the front frame 16 or the rear frame 18 and another end that is attachable to the arched top of the opposing frame so that when in a collapsed position, the handle may be secured in such a fashion so that front frame and rear frame are secured to one another. In one embodiment, the outer cover includes fasteners 52 disposed adjacent the front and rear frames for securing the front frame 16 to the rear frame 18 when in a collapsed position. Thus, the front and rear frame can be used as a handle to aid in transport of the diaper changing station when in a collapsed position.
Referring now to FIG. 5, the collapsible nature of the diaper changing station can be more clearly seen. For easy transport, diaper changing station may be collapsed whereby the domed top, sides and base all fold inwardly so that the entire collapsed station has a shape generally matching that of the front and rear frames 16 and 18. Fasteners 52 allow front and rear frame to be secured along the domed top and sides of front and rear frame so that the changing station remains secured in a collapsed position during transport. Extension 48 may be secured to front frame 16 via the use of fasteners 49 so that the extension does not become snagged or torn during transport.
While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
