DETAILED DESCRIPTION OF THE INVENTION

[0036] In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms of direction or position, refer to the device as it is oriented and appears in the drawings and are used for convenience only, and such are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation.

[0037] Now referring to drawings in FIGS. 1-15, wherein similar components are identified by like reference numerals, there can be seen in FIGS. 1-2 the cover device 10, which is adapted to engage with an infant carrier 12, in an engaged position upon such a conventional infant carrier 12. In the depicted engaged position of the cover device 10 with a conventional carrier 12, shown in FIGS. 1-2 and 7-10, elastic 14 is engaged at or adjacent to the perimeter edge 25 of the opening 27 of the body 16 of the device 10. In the mode of the device 10 of FIG. 1-2, the elastic 14 contracts with the device 10 in the engaged position and provides a circumferential biased contact of the sidewall 19 portion of the body 16 of the cover device 10, against a circumferential exterior surface of a carrier sidewall 17 of such a conventional infant carrier 12.

[0038] The fabric forming the body 16, or at least the sidewall 19 thereof, as noted, is preferably elastic and will cause the body sidewall 19 to form to the contours of the sidewall 17 of the infant carrier 12 and form a contact against it and eliminate any gaps in the formed circumferential seal which is most important to keep out particulate.

[0039] In the mode of the device 10 of FIGS. 1-10, the biased engagement of the elastic 14, which is engaged to the body 16 and surrounds an opening 27 through which the carrier 12 engages into the body 16, serves to form a sealing point or circumferential seal of the body 16 of the cover device 10 against the carrier sidewall 17 of the carrier 12. It, thus, serves to insure air communicated into the interior cavity 18 follows a flow path to prevent unfiltered air from being communicated to the interior cavity 18 of the carrier 12 where an infant or small child would sit. In most instances where the filter device 10 is so engaged with a carrier 12, as it is adapted to do so, the body 16 of the cover device 10 will contact against the carrier sidewall 17 substantially along a contact line 13 and this contact forms a circumferential of the body 16 against the sidewall 17, which is maintained by the biased engagement of the sidewall 19 of the body 16 against the carrier, which is enabled by the elastic 14.

[0040] In a mode of the device 10 with shorter sidewalls 19, the contact line 13 will be at or adjacent an upper edge of the carrier sidewall 17 on the exterior side of the carrier 12, where the carrier sidewall 17 surrounds and defines the interior cavity 18. However, this may vary depending on the shape of the carrier 12. With the elastic 14 at or adjacent the perimeter edge of the body 16 and contracting to bias the sidewall 19 of the body 16 against the exterior surface of the carrier sidewall 17, the circumferential seal around the exterior of the carrier 12 is also formed along this contact line 13.

[0041] As shown, the cover device 10 is formed of a body 16 having a pocket 26 within the top wall 23 which is formed of a first sidewall 22 or sidewall portion which is opposite a second sidewall 24 or sidewall portion. The pocket 26 (FIG. 5) is, thus, formed between the two sidewall portions in all modes of the device. The pocket 26 is sized for insertion of a removably engageable filter element 20 of substantially the same size therein, through a pocket opening 28 providing access to the pocket 26.

[0042] Elastic 14 is preferably engaged to the perimeter edge of the body 16 of the cover device 10 which surrounds the opening 27 through which the carrier 12 is passed, as it is positioned within the interior cavity 18, to put the body 16 in a mounted position, such as in FIG. 1 or FIG. 11. The elastic 14 may be sewn or glued or otherwise attached to the perimeter edge surrounding the opening 27, and in a default state, contracts to form a compressive engagement of the perimeter edge of the body 16, around and against the exterior surface of the sidewall 17 of the infant carrier 12 such as in FIGS. 1-2 and 6-7.

[0043] The first sidewall 22 and opposing second sidewall 24, on the opposite side of the formed pocket 26, are preferably formed of woven or non woven material having openings between the yarn or fibers forming the material. Shown herein is one preferred mesh material having mesh openings 30 therein which is porous and easily passes air therethrough. However, the material forming one or both of the first sidewall 22 and second sidewall 24 forming the sides of the pocket 26 may be woven fabric having mesh openings 30 between the yarn or threads in the weave or knit, with decorative patterns thereon and opaque in that it would block the view into and out of the interior cavity 18 and the carrier and provide shade.

[0044] The filter element 20, when inserted into the pocket 26, filters the air which is communicated to the interior cavity 18. Thus, with the body 16 of the device 10 in an engaged position upon the carrier 12, air follows a flow path which communicates through the mesh openings 30 in the first sidewall 22, then through said air passages in the filter element 20, and finally through the openings in the fabric forming the second sidewall 24, before that airflow reaches the interior cavity 18 and the carrier and any occupant therein. The air following this defined flowpath is, thus, filtered by both the mesh openings 30 and especially by the air passages 32 of the filter element 20, before reaching the occupant in the interior cavity 18.

[0045] The mesh fabric forming the first sidewall 22 and second sidewall 24, preferably, is knitted or woven or non woven fabric formed in a manner to maintain the spacing and size of the mesh openings 30 to maximize airflow therethrough. One preferred fabric with these characteristics is a polymeric coated mesh such as that sold by Phifer Incorporated, which is formed of vinyl coated fiberglass or polyester in an 18×14 or 18×16 weave. Such material, being vinyl coated, has been found to fix the size of the openings between threads forming it which maintains the openings 30 in their maximum size no matter the position or bend or fold of the material. This insures a maximum airflow through the openings 30 in the first sidewall 22, through the filter element 20, and then through the openings 30 in the second sidewall 24 to the occupant of the interior cavity 18 and the carrier 12 therein. Such a fabric, with fixed mesh openings 30, is preferred for the sidewalls forming the pocket 26.

[0046] However, as noted, in many cases, it is more desirable to employ a woven or non woven plain or decorative print fabric with mesh openings 30 between yarns. Such will provide shade and a blocked view into and out of the carrier 12. This configuration aids in shading the occupant and provides a calm space for napping. Such will work well as long as the openings between yarns or threads forming the woven or knitted fabric, will allow air passage therethrough.

[0047] Shown in FIG. 4 is the pocket 26 of the cover device 10 as in FIGS. 1-3 and 11-14 in an exploded view. As depicted, the filter element 20 is removed from engagement within a pocket 26 in the body 16 of the cover device 10. Also shown are the filter gauge strip 42 which is positioned to align with the pocket aperture 43 in the cover device 10 if employed. This pocket aperture 43 is positioned to register with and align with the filter gauge strip 42, and thereby allows the user to easily ascertain the current state of the filter element 20 while it is engaged within the pocket 26 without having to remove it to do so. The width and length of the planar filter element 20 are sized substantially equal to that of the pocket 26 so as to allow for a snug planar fit of the filter element 20 within the confines and perimeter defining the pocket 26.

[0048] While the pocket 26 is shown in FIG. 4 to cover substantially the entire upper area of the body 16 of the device 10, it may be formed smaller with a matching filter element 20. For example, the pocket 26 and engaged filter element 20 may be sized smaller than the top surface or panel of the body 16 within an area surrounded by the contact line 13 of the body 16 which contacts against the exterior of the carrier 12. This would be appropriate where the body 16 extends around the outside surface of the carrier sidewall 17 to the elastic 14, but first makes contact at a contact line 13 running around the exterior surface of the carrier sidewall 17. Since the seal, formed at the contact line 13, is closer to the interior cavity 18, occupied by an infant or child, a smaller pocket 26 engaged with a substantially equal sized filter element 20 may be employed which may reduce cost.

[0049] Further, it is anticipated that different fabric may be employed about a perimeter area of the body 16 which may prevent air passage therethrough, such as vinyl or sealed rip-stop material or the elastic material noted as used in the mode of the device of FIGS. 11-15. This fabric body sidewall 15 would, thus, surround and contact against the carrier sidewall 17 and form a circumferential seal around the sidewall 17 of the carrier 12. In this mode, the pocket 26 and filter element 20 can be formed in a smaller area formed of the woven or mesh fabric, such as or example within the contact line 13. The area of the body 16 outside the exemplar contact line 13 can be formed of material which will prevent air passage or of elastic material which will form a contoured circumferential seal around the carrier sidewall 17 and prevent air passage. This mode will also allow for a smaller pocket 26 and substantially equal sized filter element 20.

[0050] In one current preferred mode of the device 10, the filter element 20 is formed of woven or non woven polymeric material, such as polymeric expanded foam or elongated polymeric filter fibers placed, in fixed engagements to each other in a manner to maintain an opening size of air passages 32 communicating through the filter element 20. Currently, a preferred air passage 32 diameter of passages communicating through the filter element 20, is substantially 1.5 to 0.4 microns. This size range was found to work best in experimentation and is preferred in order to capture or render harmless the maximum amount of bugs, pollen, particulate, and pathogens in the air. Such is available in both expanded polymeric foam material filters and non woven polymeric fiber material filters and the like.

[0051] Additionally preferred is the employing filter material forming the expanded foam or fibers defining the filter element 20, which is impregnated with or includes one or a combination of anti-pathogenic materials from a group of anti-pathogenic materials including silver ions, nickel ions, and activated carbon. Such can be added to the polymeric mix of material employed for forming either a foam filter or a fiber material filter during manufacture. These anti-pathogenic materials act to kill germs and viruses and other pathogens which may be in the air which communicate through the passages 32 of the filter element 20, when the filter is operatively engaged within the pocket 26.

[0052] FIG. 5 shows a sectional view across lines 5-5 of FIG. 4 showing the body 16 of the cover device 10 having the filter element 20 removably positioned within the pocket 26 formed between a first sidewall 22 and second sidewall 24 forming the top wall 23 of the body 16 of the cover device 10. By top wall 23 is meant the area of the body 16 in between the body sidewall 19 which contacts against the carrier sidewall 17 and which is positioned over an occupant of the carrier 12. Also depicted is the elastic 14 which, as noted, is preferably positioned around a perimeter of the opening 27 in the body 16 to provide the biased engagement around the circumference of the sidewall 17 of a carrier 12.

[0053] Depicted in FIG. 6 is another view of a removably engageable filter element 20. In this view is also shown an optional aperture 34. One or more apertures 34 may be formed to align with a viewing opening 36 (FIG. 6) formed in the sidewalls 22 and 24 defining the pocket in the top wall 23 of the body 16 and/or a handle opening 38 communicating through the body 16 which allows the grasping of the handle 40 of the carrier 12 during transport. Thus, one or more apertures 34 can be positioned in the filter element 20 which align with viewing openings 36 in both sidewalls of the body 16, and/or handle openings 38 communicating through both sidewalls 22 and 24 of the pocket 26 in the top wall 23 of the body 16.

[0054] Additionally shown in FIG. 6 is the visually discernable filter gauge strip 42 which reacts with the atmosphere over a calculated time period, and/or with pathogens, and changes color or appearance to signal that the filter element 20 should be replaced. The gauge strip 42 can for instance be impregnated with reagents which change appearance upon contact with the atmosphere over a determined duration, and/or, upon contact with the reagents with chosen pathogens determined particularly important.

[0055] Depicted in FIG. 7 is the device 10 herein in the engaged position on a carrier 12 as in FIG. 1-2. In this mode of the device 10 the view opening 36 is provided which communicates through both sidewalls of the pocket in the body 16 and through an aligned aperture 34 in the filter element 20. The view opening 36 allows a user to look at the occupant of the interior cavity 18 and in carrier 12 as needed. Preferably a cover flap 37 is positioned to cover the view opening 36 when not in use to prevent air passage therethrough. The cover flap 37 may be a solid material so as to prevent air passage therethrough since the filter element 20 will not be present in the view opening 37.

[0056] FIG. 8, shows a mode of the device 10, as in FIG. 7, showing an optional handle opening 38 communicating through the sidewalls 22 and 24 of the pocket and top wall 23 of the body 16. In this mode, an aperture 34 may also be formed into the filter element 20 which would align with the handle opening 38 once the filter element 20 is engaged in the pocket 26. A cover flap 37 (FIG. 7) is preferably positioned to cover this handle opening 38 when not in use. Of course, differing modes of the cover device 10 can have one or both of the viewing opening 36 and the handle opening 38, and the filter element 20 will be configured with one or more apertures 34 registered in positions to properly align with such.

[0057] A particularly preferred mode of the cover device 10 herein is shown in FIG. 9 and FIG. 11. In this mode of the device 10, an engagement to the handle 40 is provided that maintains the sealed interior cavity 18 but connects the top wall 23 to the handle 18 to hold it elevated when the body 16 is in an engaged position. As shown in FIG. 9, at least one handle connector 44, such as the depicted straps 46, are included. The connectors 44 are removably engageable to the handle 40 of the infant carrier 12 to provide support to the body 16 of the cover device 10 to hold it underneath the lower surface of the handle 40, while still maintaining it elevated above the interior cavity 18 and the carrier occupant. This mode is especially preferred in that it allows easy access and grasping of the handle for transport of the carrier 12 but maintains the body 16 of the cover device 10 operatively engaged to shade or provide an opaque or blocked view which is helpful if the infant is napping.

[0058] Currently the handle connector 44 in FIG. 9 is formed by straps 46 which are engaged to the body 16 and have cooperative fasteners thereon such as hook and loop fabric 48 or snaps or buttons. However, other removably engageable connectors, such as the cooperative connectors, such as snaps 50 of FIG. 11, which will temporarily engage the top wall 23 with the handle 40 and support the top wall 23 and pocket of the body 16 between the body sidewall 19 and elevated above the interior cavity 18 and occupant may be employed.

[0059] This engagement to the handle 40 also maintains the aperture 34 shown with a transparent flexible window 35 which allows viewing of the occupant when the fabric forming the body 16 is decorative or opaque. As noted, other connectors 44 such as C-clips, magnets, releasable adhesive, cooperative fasteners such as snaps 50, or such connectors 44 as would occur to those skilled in the art are anticipated within the scope of this patent.

[0060] In FIG. 10 is shown a side sectional view of the body 16 of the carrier device 10 herein configured, as in all modes noted above. As shown, the body 16 has the top wall 23 having the first sidewall 22 opposite a second sidewall 24 and a pocket 26 formed therebetween where a filter element 20 is located. This filter element 20 may be permanently located in the pocket 26, however as noted above, it is preferable if the filter element 20 is removable and replaceable with other filter elements 20 sized for positioning within the pocket 26 in between the porous sidewalls 22 and 24.

[0061] Shown in FIG. 11 is another particularly preferred mode of the device 10 herein, such as in FIG. 10, but where the body 16 has an extended body sidewall 19. The extended sidewall 19, in experimentation, was found to more easily form a seal for the area of the sidewall 19 which is adjacent to and thereby biasly contacts against the circumference of the sidewall 17. In addition to the larger area of formation of the circumferential seal, the longer sidewall 19 has shown to more easily operatively engage with a larger number of carriers 12 from different manufacturers. In this mode, the sidewall 19 of the body 16 extends to the opening 27 which is positioned adjacent to the bottom edge of the carrier 12 with the carrier in the engaged position. By adjacent is meant that the opening 27 which has a perimeter edge which is positioned at the bottom edge of the carrier or in a circumferential contact against the carrier sidewall 17 within six inches of the bottom edge.

[0062] Also in this mode of the device 10, the sidewall 19 of the body 16 is formed of woven or knitted or similar material which has yarn or threads which are elastic. This is especially preferred in that it significantly increases the area of the formed circumferential seal against the carrier sidewall 17 from the contact line 13, noted above, of about an inch in width, to a contact area of the sidewall 19 against the carrier sidewall 17 which is much wider in that substantially the entire area of the sidewall 19 which is adjacent to the carrier sidewall 17, contacts against the carrier sidewall 17. Additionally, the elastic fabric forming the sidewall 19, once the carrier 12 is in the interior cavity of the body 16, will form a circumferential biased contact of the sidewall 19 against the carrier sidewall 17, which is between 2-10 inches in width and which will also form to the biased engagement with the contours of the carrier sidewall 17 and any recesses or projections thereon, for a much better seal.

[0063] Also shown in FIG. 11 are cooperative fasteners 50 positioned upon a rear flap 49 which may be removably connected to mating cooperative fasteners 50 located on the top wall 23 of the body 16. Connecting the fasteners 50 on the rear flap 49 will hold it to a substantially sealed engagement to the top wall 23 and will operate the same as the connectors 44, to hold the top wall 23 elevated above the interior cavity and the occupant of the carrier. The handle 40 is still also easily grasped.

[0064] FIG. 12 shows the device, as in FIG. 11, showing the elastic 14 which surrounds the perimeter of the formed opening 27 which is positioned adjacent the bottom side of the carrier 12. Also shown are the extended sidewall 19 of the body 16 which as noted is formed of elastic material. In this mode, the area of the sidewall 19 of the body 16, which positioned adjacent the carrier sidewall 17, with the body 16 in the engaged position, will biasly contact against it to form a much better circumferential seal.

[0065] FIG. 13 depicts the device 10 of FIGS. 11-12 in the engaged position upon a carrier showing the handle 40 extending from an area in between the rear flap 49 and the top wall 23, when the rear flap 49 is engaged to the top wall 23 by the engaged fasteners such as snaps 50. This forms a removable connection of the top wall 23 to the handle 40 in the same fashion as the connectors 44 and provides the preferred holding of the top wall 23 elevated.

[0066] In FIG. 14 is depicted the device 10 as in FIGS. 11-13 and showing the filter 20 positioned within the pocket 26 formed in the top wall 23 of the body 16. The pocket 16 is formed in the same fashion, as noted above, with a first sidewall 22 and second sidewall 24 on opposing sides of the pocket 26. One of the first sidewall 22 or second sidewall 24 can be formed by the fabric forming the tope wall 23, or it can be formed into the top wall 23 as a portion thereof. The material with fixed sized air passages 32 noted above can be employed for these sidewalls.

[0067] Finally, as shown in FIG. 15, the device 10 herein, can be configured to be engaged upon a stroller-positioned child carrier.
