Description

FIELD OF THE INVENTION

The invention relates to sleeping and resting surfaces generally and, more particularly, to a method and/or apparatus for implementing a foldable breathe-through sleep structure.

BACKGROUND

Infants, toddlers, and occasionally small children tend to sleep in cribs. Traditional cribs are often purchased along with a traditional foam or spring mattress as a set. When an infant expels bodily fluids in the crib, these mattresses may become unsanitary, as the bodily fluids may tend to pool or collect around the infant's body. Cleaning these mattresses can be cumbersome and sometimes ineffective, as the bacteria, germs and other matter can become embedded in the mattress. Traditional mattresses can also inhibit the breathing of the infant and/or cause the infant to re-breath a potentially harmful level of exhaled carbon dioxide.

It would be desirable to implement a foldable breathe-through sleep structure.

SUMMARY

The invention encompasses an aspect concerning a foldable breathe-through mattress comprising a foldable base frame, a top frame assembly, a flexible mat, and a topper. The top frame assembly may comprise a first arm, a second arm, a first frame clip, and a second frame clip. The first and second frame clips are generally attachable to the foldable base frame and the first and the second arms are generally attached by hinges to the first and the second frame clips. The flexible mat may be removably attached to a bottom of the foldable base frame. The topper may be removably attached to the first and the second arms of the top frame assembly.

The invention also encompasses an aspect concerning a method of supporting a person comprising (a) opening a foldable base frame, (b) removably attaching a flexible mat to a bottom of the foldable base frame, (c) attaching a top frame assembly to a top of the foldable base frame, where (i) the top frame assembly comprises a first arm, a second arm, a first frame clip, and a second frame clip, (ii) the first and second frame clips are attached to the foldable base frame and the first and the second arms are attached by hinges to the first and the second frame clips, (d) attaching a topper to the first and the second arms, (e) moving the arms into a closed position, and (f) latching the first and the second arms in the closed position to tension the topper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the present invention include providing a foldable breathe-through sleep structure that may (i) provide a breathe-through infant mattress, (ii) be placed in a crib, (iii) be implemented as a stand alone sleep surface, (iv) be folded for easy storage, (v) have a topper and bottom mat that may be removed and machine washed, and/or (vi) be scaled to fit infants, toddlers, and/or adults.

In various embodiments, a foldable breathe-through crib mattress (or sleep surface) may include a topper (or cover), a base frame, and a top frame assembly. The base frame generally comprises two long leg sections and four short leg sections. Ends of the long leg sections and the short leg sections are generally configured to form hinged joints. The long leg sections and the short leg sections are generally connected by the hinged joints, which allows the base frame to be folded for easy storage and transport. The top frame assembly may be removably assembled to the base frame. The top frame assembly generally comprises two arms and two frame clips. Each of the arms is generally attached to the two frame clips by hinges. The frame clips are generally configured to mount the top frame assembly to each side of the base frame at points where two of the short leg sections are connected by a hinged joint. The frame clips are generally configured to fit (wrap) over the hinged joints to lock the hinged joints in an unfolded position. In an example, the frame clips may be attached to an inner surface of the base frame sections. In an example, the frame clips may be attached using knurled thumbscrews for ease of assembly and disassembly. In various embodiments, captive knurled thumbscrews may be used in each of the frame clips to avoid loss and/or avoid a potential choking hazard.

The topper is generally removably attached to the top frame assembly. In various embodiments, the topper may be attached to the two arms of the top frame assembly using two zippers. In an example, the zippers may comprise #10 flat coil heavy duty zippers. In various embodiments, one-half of each of the two zippers may be configured to be entrapped within a respective arm of the top frame assembly. In an example, each of the zipper halves may comprise an open woven channel running a length of the zipper. In another example, material of each zipper half may be folded over and stitched to form a channel running the length of the zipper. In an example, a section of tubing may be slid into the open woven channel of each zipper half to create a bead that allows the zipper halves to be entrapped within the respective arm of the top frame assembly. In an example, each of the arms may comprise (define) an interior space configured to entrap a respective zipper half with a quarter-inch diameter section of polyethylene tubing inserted into the open woven channel of the zipper half. A second half of each of the two zippers may be sewn to a respective side edge of the topper.

In various embodiments, a siliconized mat may be attached to a bottom surface (edge) of the base frame. In an example, the siliconized mat may be attached using nylon push rivets. However, other types of fasteners may be used. In an example, the siliconized mat may be configured such that bodily fluids that pass through the topper are held within a cavity defined by the foldable base frame.

The topper, which replaces a traditional mattress structure, may include a number of layers. In an example where the foldable breathe-through crib mattress (or sleep surface) is employed in a standard crib, the topper may have length and width dimensions of about fifty-one (51) inches by twenty-seven (27) inches (1295.4 millimeters by 685.8 millimeters). In another example, the topper may have length and width dimensions of about fifty-three and one-half (53.5) inches by about thirty (30) inches (1359 millimeters by 762 millimeters). However, other length and width dimensions suitable for bedding used by children may be implemented accordingly to meet design criteria of a particular application.

In an example, the topper may be fabricated using fabric including fluid-wicking yarns or fibers that are warp-knitted in an open-weave fashion. In an example, a knitted mesh including sinusoidal mesh strands extending generally parallel to each other may be used. The strands may be spaced apart from each other and connected to each other via a plurality of threads or a plurality of groups of threads that are spaced apart from each other. In this manner, the strands and threads of the fabric of the topper may cooperate to form a mesh having a plurality of polygonal, circular or oval-shaped openings (or holes).

The fabric used to make the topper may be permeable to fluids, dissipate heat, and/or facilitate airflow. In an example, the topper fabric may include a portion formed from micro-denier fibers. An example of a suitable micro denier fiber would be spun polyester fibers having an average denier of 70 or more. In an example, a suitable fabric for making the topper may include, but is not limited to, a three-dimensional (3D) knit spacer fabric. In some embodiments, the topper may comprise one hundred percent monofilament polyester that may be fire resistant, mildew resistant, and/or resistant to alkaloids and acids. However, other materials and fabrics may be used that allow air to relatively easily and passively flow through the topper and are capable of performing the functionality described herein. The topper may also include a spacer fabric or a breathable polyester netting layer that may be substantially inelastic and dimensionally stable such that the netting has little or no stretch when placed under tension loads. The netting (or spacer fabric) may be sewn across a plane of an underside of the topper to provide stability and/or to increase firmness.

The topper fabric generally allows substantially free flow of air up and down through the topper. Air passage and circulation is generally aided by the cavity defined by the base frame and a number of openings (or slots) in sidewalls of the base frame. In an example, the structure and function of the foldable breathe-through mattress generally allows an infant to lie face-down on the topper and not re-breath a potentially harmful level of carbon dioxide and/or germs. The fabric of the topper generally wicks liquids and moisture away from an outer surface of the topper, providing numerous health, safety and hygienic benefits over conventional mattresses. The substantially free flow of air also allows the infant to maintain a relatively consistent body temperature compared to conventional mattresses or plastic protective sheets. Furthermore, due to the ease of installation and removability of the topper from the top frame assembly, the topper of the foldable breathe-through mattress may be quickly and easily removed and washed in a conventional washing machine to remove stains, bacteria, and other material.

In an example embodiment, the foldable base frame may comprise two (2) long leg sections and four (4) short leg sections. In various embodiments, the long leg sections and the short leg sections may be assembled together using pins to form hinges that allow the base frame to fold. In an example, the ends of the long leg sections and the short leg sections may be configured to form the hinges with an offset pivot axis to allow the sections to fold flat against each other. In an example, the pins may be implemented using one-eighth inch diameter stainless steel rods. In various embodiments, the foldable base frame generally has rounded corners and edges to prevent injury. In an example, the ends of the long leg sections and the short leg sections are configured to rotate relative to each other such that a possibility of being pinched by the hinges is reduced. In various embodiments, the base frame may be formed from various materials including, but not limited to, aluminum, steel, or any other metallic material, wood, polymeric, and/or composite material having sufficient strength and rigidity. In an example, the base frame may be manufactured using high-density polyethylene (HDPE). In an example, the base frame may be manufactured using a blow molding process. In another example, the base frame may be manufactured using an injection molding process. However, other types of manufacturing processes may be used.

In various embodiments, the arms of the top frame assembly generally have rounded corners and edges to prevent injury. In various embodiments, the arms of the top frame assembly may be formed from various materials including, but not limited to, aluminum, steel, or any other metallic material, wood, polymeric, and/or composite material having sufficient strength and rigidity. In an example, the arms of the top frame assembly may be manufactured using high-density polyethylene (HDPE). In an example, the arms of the top frame assembly may be manufactured using a blow molding process. In another example, the arms of the top frame assembly may be manufactured using an injection molding process. However, other types of manufacturing processes may be used.

In various embodiments, the foldable breathe-through crib mattress (or sleep surface) may be suitable for use by babies, infants, toddlers, and/or young children (hereinafter collectively referred to as “children”). In some embodiments, the foldable breathe-through crib mattress (or sleep surface) may be mounted or retrofitted to a traditional crib. In still other embodiments, the foldable breathe-through crib mattress (or sleep surface) may be a stand-alone unit that may be placed on a floor or other surface. The foldable breathe-through crib mattress (or sleep surface) generally provides safe, hygienic, and comfortable bedding for children. In contrast to conventional crib mattresses, the fabric portions of the foldable breathe-through crib mattress (or sleep surface) may be easily removed for washing.

With reference to FIGS. 1-8, a foldable breathe-through crib mattress (or sleep surface) 100 is provided that may include a foldable base frame 102, a top frame assembly 104, and a topper (or cover) 106. In various embodiments, the foldable base frame 102 may support the topper 106 mounted on the top frame assembly 104. In an example embodiment, the foldable base frame 102 may comprise two (2) long leg sections 118, two (2) right-hand short leg sections 122, and two (2) left-hand short leg sections 124. In an example, the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 may include a plurality of openings 120 which allow a free flow of air. In various embodiments, the long leg sections 118, the right-hand short leg sections 122, and left-hand short leg sections 124 may be assembled together using pins 154 to form hinges that allow the foldable base frame 102 to fold. In an example, the hinge pins 154 may be implemented using one-eighth inch diameter stainless steel rods. In an example, a flexible mat 117 may be attached to a bottom surface of the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124. In an example, the flexible mat 117 may be connected to the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 using nylon rivets that are press-fit into holes in the bottom surface of the long leg sections 118, the right-hand leg sections 122, and the left-hand short leg sections 124. In various embodiments, the foldable breathe-through crib mattress (or sleep surface) 100 may be suitable for use by babies, infants, toddlers, and/or young children (hereinafter collectively referred to as “children”).

Referring to FIG. 1, a perspective view is shown illustrating a foldable breathe-through crib mattress (or sleep surface) 100 in accordance with an embodiment of the invention installed in a crib 10. In an example, the foldable breathe-through crib mattress (or sleep surface) 100 may be mounted in or retrofitted to a standard crib 10. In an example, the foldable breathe-through crib mattress (or sleep surface) 100 may comprise a foldable base frame 102, a top frame assembly 104, and a topper (or cover) 106. In various embodiments, the foldable base frame 102 may support the topper 106 mounted on the top frame assembly 104. In various embodiments, the foldable base frame 102 may comprise latch members 130 configured to lock arms of the top frame assembly 104 to the foldable base frame 102 during use.

In various embodiments, the topper 106, which replaces a traditional mattress structure, according to the teachings of the present disclosure, may include an upper layer 108, a bumper 114, and zipper halves 116. The bumper 114 may be an elongated member extending around a perimeter 110 of the topper 106. The bumper 114 may be sized and positioned relative to the topper 106 to provide a barrier and cushion over the top frame assembly 104 to protect a child lying in the foldable breathe-through crib mattress (or sleep surface) 100. In an example, the bumper 114 may include a fabric outer layer encasing a filler material to form a generally circular cross section. In an example, the bumper 114 may include, but is not limited to, a diameter of about one and one-half (1.5) inches to two and one-half (2.5) inches (38-64 millimeters).

In an example, the bumper 114 may be formed from a breathable spacer fabric and may be connected to the perimeter 110 of the topper 106 at a stitched seam. The filler material may be a resiliently compressible material. One example includes a six-layer polyester filler material manufactured by Petco Sackner and sold under the product designation jute braided polyester. However, other suitable cushioning material may be used. The bumper 114 may also include a break or slit 112 at opposing ends of the topper 106 to facilitate installation and removal of the topper 106 from the top frame assembly 104. It will be appreciated that the structure of the bumper 114 is not limited to the structure described above and may include alternatively configured dimensions and/or materials.

In an example, the zipper halves 116 may extend downward (relative to the view shown in FIG. 1) on each side of the topper from the stitched seam connecting the upper layer 108 and the bumper 114. The zipper halves 116 are generally configured to engage an entrapped zipper half 162 in each arm 160 of the top frame assembly 104.

Referring to FIG. 2, a perspective view is shown illustrating the foldable breathe-through mattress with a topper in accordance with an embodiment of the invention. In some embodiments, the foldable breathe-through crib mattress (or sleep surface) 100 may be implemented (configured) as a stand-alone unit that may be placed on a floor or other surface. As will be subsequently described, the foldable breathe-through crib mattress (or sleep surface) 100 generally provides safe, hygienic and comfortable bedding for children.

In various embodiments, the topper 106, which replaces a traditional mattress structure, according to the teachings of the present disclosure, may include an upper layer 108, a bumper 114, and a zipper half 116. When employed in a standard crib 10, the topper 106 may have length and width dimensions, for example, of about fifty-one (51) by twenty-seven (27) inches (1295.4 millimeters by 685.8 millimeters). In another example configuration, the topper 106 may have length and width dimensions, for example, of about fifty-three and one-half (53.5) inches by about thirty (30) inches (1359 millimeters by 762 millimeters). It will be appreciated that the topper may be implemented with other length and width dimensions suitable for a sleep surface used by children.

The upper layer 108 may be formed from a “spacer” fabric including fluid-wicking yarns or fibers that are warp-knitted in an open-weave fashion. The upper layer 108 may be a knitted mesh including sinusoidal mesh strands extending generally parallel to each other. The strands may be spaced apart from each other and connected to each other via a plurality of threads or a plurality of groups of threads that are spaced apart from each other. In this manner, the strands and threads of the fabric of the upper layer 108 may cooperate to form a mesh having a plurality of polygonal, circular, or oval-shaped holes. The upper layer 108 is generally permeable to fluids, dissipates heat, and facilitates airflow there-through. In an example, the spacer fabric may include a top panel in contact with the child, formed from micro-denier fibers, a bottom panel which supports the top panel and a “spacer” which sticks the top and bottom panels together to form a three dimensional fabric. An example of a suitable micro denier fiber would be spun polyester fibers having an average denier of 70 or more. Examples of suitable “spacer” fabric include a three-dimensional knit spacer fabric marketed under the brand name D³ manufactured by Gehring Textiles, Inc. in Garden City, N. Y. Another suitable material for the upper layer 108 is marketed under the name 3MESH manufactured by Muller Textile located in Germany. In some embodiments, the upper layer 108 may be one hundred percent monofilament polyester that may be fire resistant, mildew resistant, and resistant to alkaloids and acids. Other materials and fabrics may be used that allow air to relatively easily and passively flow through the upper layer 108 and are capable of performing the functionality described herein.

The bumper 114 may be an elongated member extending around a perimeter 110 of the topper 106, as shown in FIGS. 1 and 2. The bumper 114 may be sized and positioned relative to the topper 106 to provide a barrier and cushion over the top frame assembly 104 to protect a child lying in the foldable breathe-through crib mattress (or sleep surface) 100. The bumper 114 may include a fabric outer layer encasing a filler material to form a generally circular cross section. By way of non-limiting example, the bumper 114 may include a diameter of about one and one-half (1.5) inches to two and one-half (2.5) inches (38-64 millimeters). The bumper 114 may be formed from the breathable spacer fabric described above, for example, and may be connected to the topper 106 at the stitched seam. The filler material may be a resiliently compressible material. One example includes a six-layer polyester filler material manufactured by Petco Sackner and sold under the product designation n jute braided polyester. However, other suitable cushioning material may be used. The bumper 114 may also include a break or slit 112 at opposing ends of the topper 106 to facilitate installation and removal of the topper 106 from the top frame assembly 104. It will be appreciated that the structure of the bumper 114 is not limited to the structure described above, and may include alternatively configured dimensions and/or materials.

The zipper halves 116 may extend downward (relative to the view shown in FIG. 1) from the stitched seam connecting the upper layer 108 and the bumper 114. The zipper halves 116 are generally configured to engage entrapped zipper halves 162 in the arms 160 of the top frame assembly 104, forming a zipper connection between the topper 106 and the top frame assembly 104.

In various embodiments, the foldable base frame 102 may support the topper 106 mounted on the top frame assembly 104. In an example embodiment, the foldable base frame 102 may comprise two (2) long leg sections 118, two (2) right-hand short leg sections 122, and two (2) left-hand short leg sections 124. In an example, the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 may include a plurality of openings 120 which allow a free flow of air. In an example, the long leg sections 118 may comprise a number of risers 128. The risers 128 generally provide support for the top frame assembly 104 while allowing access to lift the arms of the top frame assembly 104 (e.g., for access to an interior cavity of the foldable breathe-through mattress, to remove the topper 106 from the top frame assembly 104, etc.). In some embodiments, the right-hand short leg sections 122 and the left-hand short leg sections 124 may also be implemented with one or more risers 128. In various embodiments, the foldable base frame 102 may comprise latch members 130 configured to lock the arms of the top frame assembly 104 against the risers 128 of the foldable base frame 102 during use.

The topper 106 may include a pair of panels (or flaps) 150. The panels 150 may cover and allow access to latch mechanisms of the first and the second arms of the top frame assembly 104. The latch mechanisms may be configured to securely retain each of the arms of the top frame assembly 104 in a closed position (e.g., against the risers 128 of the foldable base frame 102). In an example, the flaps 150 may be stitched to the topper 106 along one edge. In an example, the flaps 150 may be held closed over the latch mechanisms of the first and the second arms of the top frame assembly 104 by hook and loop type fasteners attached to remaining edges of the flaps 150.

Referring to FIG. 3, a diagram is shown illustrating a perspective view of the foldable breathe-through crib mattress of FIG. 2 having a first arm 160 of the top frame assembly 104 in an open position and a second arm 160 of the top frame assembly 104 in a locked position (not visible). With the first arm 160 of the top frame assembly 104 in the open position, an interior cavity of the foldable breathe-through crib mattress 100 is visible showing a flexible bottom mat 117 forming a bottom of the interior cavity of the foldable base frame 102. In an example, the flexible bottom mat 117 may be attached to a bottom surface of the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 of the foldable base frame 102. In an example, the flexible bottom mat 117 may be connected to the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 using nylon rivets that are press-fit into holes in the bottom surface of the long leg sections 118, the right-hand leg sections 122, and the left-hand short leg sections 124.

In the particular embodiment shown in FIGS. 1-8, the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 of the foldable base frame 102 provide four vertically-extending sidewalls that cooperate with the bottom mat 117 to form a generally rectangular box. In various embodiments, the top frame assembly 104 and the topper 106 may be mounted to topsides of the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 such that the topper 106 cooperates with the long leg sections 118, the right-hand short leg sections 122, the left-hand short leg sections 124, and the bottom mat 117 to form an enclosed cavity.

In various embodiments, the topper 106, which replaces a traditional mattress structure, according to the teachings of the present disclosure, may also include a lower (or bottom) layer 152. The lower layer 152 may be formed, for example, from a spacer fabric or a breathable polyester netting that may be substantially inelastic and dimensionally stable such that the lower layer 152 has little or no stretch when placed under tension loads. The top layer 108, the bumper 114, the zipper halves 116, and the lower layer 152 may be joined together by a stitched seam. The netting (or spacer fabric) of the lower layer 152 may be further sewn across a plane of an underside of the topper 106 to provide stability and/or to increase firmness of the topper 106.

In various embodiments, the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 may include a plurality of openings 120 extending there-through in communication with the enclosed cavity. The openings 120 may be vertically spaced apart from the flexible bottom mat 117. While the openings 120 are illustrated as being generally elongated slots, the openings 120 may be formed in any shape or manner to facilitate aesthetic appeal and airflow into and out of the enclosed cavity.

The top frame assembly 104 may function as a tensioning device. The top frame assembly 104 may include first and second arms 160. In various embodiments, the first and second arms 160 may be implemented having a generally U-shaped structure. In various embodiments, the first and second arms 160 may be implemented having generally rounded corners and edges. In various embodiments, the first and second arms 160 may be removably attached to the foldable base frame 102 by frame clip assemblies 172. In an example, the frame clip assemblies 172 may be removably attached to the right-hand short leg sections 122 and the left-hand short leg sections 124. Corresponding distal ends 166 and 168 of the first and second arms 160 are generally connected to each other and to the foldable base frame 102 via hinges 174 and 176 of the frame clip assemblies 172. In an example, the first and second arms 160 may be formed from tubular aluminum or steel, for example, or any other metallic, wooden, polymeric or composite material having sufficient strength and rigidity. In another example, the first and second arms 160 may be formed from high-density polyethylene (HDPE) using at least one of a blow molding process and an injection molding process.

The hinges 174 and 176 of the frame clip assemblies 172 generally allow the first and second arms 160 to pivot between a closed (or locked) position and an open (or unlocked) position (e.g., illustrated in FIG. 7). The first and second arms 160 may pivot relative to each other and/or the foldable base frame 102 simultaneously or independently from each other. The hinges 174 and 176 may include springs or other biasing members to urge the first and second arms 160 toward the open positions.

The first and second arms 160 may comprise latch mechanisms to securely retain each of the first and the second arms 160 in the closed positions (e.g., against the risers 128 of the foldable base frame 102). In an example, each of the latch mechanisms may include a male member 170 and a female member 130. The male members 170 may be mounted to the first and second arms 160. When the first and the second arms 160 are in the closed position, the male members 170 may protrude through openings 171 in the female members 130. The female members 130 may be mounted to the two long leg sections 118. The two long leg sections 118 may be configured to facilitate attachment of the female members 130. In an example, a spacer 134 may be attached to a top surface of the female members 130. The spacer 134 may be configured to ensure a tight, secure fit between the female members 130 and a bottom of the arms 160. The spacer 134 may also be configured to prevent movement of the arms 160 at the latch location due to movement on the surface of the topper 106. The male members 170 of the latch mechanisms may be spring-loaded such that the male members 170 may be pressed or snapped into engagement with the female members 130. A user may release the engagement between the male members 170 and the female members 130 by rotating a knob of the male members 170.

In an example, the knob of the male members 170 may be configured as push-to-lock, push-to-release. When pushed to lock, the knob generally becomes latched in a position that is flush with a top surface of the respective arm 160. When pushed to release, the knob is generally configured to pop up to allow the knob to be rotated to unlatch the male member 170 from the female member 130. It will be appreciated that the latch mechanisms could be other types of latch, clasp, or closure that selectively allow and prevent movement of the first and/or second arms 160 relative to the foldable base frame 102.

In an example, the stiffener 214 may be fastened to internal structures of the first ninety-degree bend section 190a, the center section 190b, and the second ninety-degree bend section 190c.

Referring to FIG. 16, a diagram is shown illustrating a detailed view of a mortise and tenon connection and a stiffener bar of an arm 160 in accordance with an embodiment of the invention. In an example, the first ninety-degree bend section 190a may comprise a tenon 210 and the center section 190b may comprise a mortise 212. The tenon 210 and the mortise 212 are generally configured to form the joint 198 which rigidly connects the first ninety-degree bend section 190a to the center section 190b. The second ninety-degree bend section 190c is generally connected similarly to the center section 190b. In an example, the tenon 210 and the mortise 212 may be locked together using a couple of fasteners (e.g., machine screws, etc.).

Referring to FIG. 17, a diagram is shown illustrating a cross-sectional view of an arm 160 in accordance with an embodiment of the invention. In an example, the arm 160 generally defines an internal space 250 configured for entrapping the zipper half 162. In an example, the internal space 250 of the arm 160 is generally configured to entrap the zipper half 162 with the section of tubing inserted into the open woven channel 202 when the bottom plates 192a and 192b are attached. In an example, with the open woven channel 202 holding the tubing 200 in the internal space 250, a remainder of the zipper half 162 extends outside the arm 160 through a gap between the bottom plates 192a and 192b and the stiffener 214.

Referring to FIGS. are shown Referring to 18A-18C, diagrams illustrating the female member 130 of a latch assembly which, when mounted on the foldable base frame 102, engages a push-to-close latch with pop-out knob that may be used to lock the arms 160 of the top frame assembly 104 to the foldable base frame 102. In an example illustrated in FIG. 18A, the female member 130 may have a spacer 134 attached depending on a distance between the arm 160 and the foldable base frame 102. In another example, the spacer 134 may be omitted when not needed (e.g., as illustrated by FIG. 18B. In various embodiments, an interior of the female member 130 (e.g., illustrated in FIG. 18C) is generally configured to engage with the mounting feature 184 of the long leg sections 118. In an example, the female member 130 may be fastened to the mounting feature 184 of the long leg sections 118 using a number of fasteners (e.g., screws, etc.).

Referring to FIG. 19, a diagram is shown illustrating a siliconized mat that attaches to the bottom of the base frame of the foldable breathe-through mattress. In an example, the flexible bottom mat 117 may have a first side 117a that is an exposed fabric side of the bottom mat and a second side 117b that is impregnated with silicone (or other treatment) to provide a fluid proof barrier. The flexible bottom mat 117 is generally mounted to the base frame 102 with the siliconized side 117b facing inward toward the enclosed cavity of the foldable breathe-through mattress 100. The silicone coating generally allows any fluid passing through the topper 106 to be caught in the cavity of the foldable breathe-through mattress 100 to reduce cleanup. In an example, the flexible mat 117 may be attached to a bottom surface of the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124. In an example, the flexible mat may be connected to the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124 using nylon rivets that are press-fit into holes 180 in the bottom surface of the long leg sections 118, the right-hand leg sections 122, and the left-hand short leg sections 124. In an example, the flexible mat 117 may define a plurality of holes 220 around a periphery of the flexible mat 117 through which the nylon rivets may be passed to attach the flexible mat 117 to the bottom surface of the long leg sections 118, the right-hand short leg sections 122, and the left-hand short leg sections 124.

Referring to FIG. 20, a diagram is shown illustrating a push-to-close latch with pop-out knob in accordance with an embodiment of the invention. In an example, a push-to-close latch with pop-out knob is generally used to implement the male member of the latch assemblies of the arms 160 of the top frame assembly 104. In an example, the male members 170 of the latch assemblies may have a latching pawl 300 that may be spring-loaded such that the male members 170 may be pressed or snapped into engagement with the female members 130 mounted on the foldable base frame 102. A user may release the engagement between the male members 170 and the female members 130 by releasing and rotating a knob 302 of the male members 170. In an example, the knob 302 of the male members 170 may be configured as push-to-lock, push-to-release. When the knob 302 is pushed to lock, the knob 302 generally becomes latched in a position that is flush with a top surface of the male members 170. When the knob 302 is pushed to release, the knob 302 is generally configured to pop up above the top surface of the male members 170 to allow the knob 302 to be rotated to unlatch the male members 170 from the female members 130. In an example, the male members 170 are attached to the arms 160 by nuts 304. In an example, the nut 304 is configured to fit within a depression in a bottom surface of the arms 160 between the bottom plates 192a and 192b.

With reference to FIGS. 1-20, operation of the foldable breathe-through crib mattress (or sleep surface) 100 has been described in detail. As described above, the topper 106 is formed from breathable materials that allow passive flow of gases and liquids there-through. The top frame assembly 104 generally retains the topper 106 in tension over the foldable base frame 102 and bottom mat 152 to form an enclosed cavity. The foldable base frame 102 may function as a receptacle for bodily fluids and other liquids that may come into contact with the topper 106. The materials and structure of the topper 106 generally provides a more sanitary sleeping surface for an infant and prevents the infant from re-breathing a potentially harmful level of exhaled carbon dioxide.

To install the topper 106 onto the top frame assembly 104, the zipper half 116 of a first side of the topper 106 is zipped to the entrapped zipper half of one arm 160 of the top frame assembly 104. The arms 160 of the top frame assembly 104 are held in the open position while the zipper half 116 of a second side of the topper 106 is zipped to the entrapped zipper half of the other arm 160 of the top frame assembly 104. Once the topper 106 has been zipped onto the arms 160 of the top frame 104, the arms 160 may be moved to the closed position and the male members 170 of the latch assemblies locked into the female members 130 attached to the foldable base frame 102.

Moving the first and second arms 160 of the top frame 104 into the closed position applies a tension force on the topper 106, such that the topper 106 is substantially taut when the arms 160 of the top frame assembly 104 are in the closed position. Such tension in the toper 106 allows the topper 106 to be suspended over the foldable base frame 102 and support the weight of the infant while maintaining the spacing between the topper 106 and the bottom mat 152 forming the enclosed cavity of the foldable base frame 102.

As described above, the “spacer” fabric of the topper 106 generally allows substantially free flow of air up and down through the topper 106. Air passage and circulation is aided by the enclosed cavity defined by the foldable base frame 102 and the openings 120 in the long leg sections 118 and the right-hand and left-hand short leg sections 122 and 124. Such structure and function allows an infant to lie face-down on the topper 106 and not re-breath a potentially harmful level of carbon dioxide and/or germs, for example. The “spacer” fabric wicks liquids and moisture away from the outer surface of the topper 106, providing numerous health, safety and hygienic benefits over conventional mattresses. The substantially free flow of air also allows the infant to maintain a relatively consistent body temperature compared to conventional mattresses or plastic protective sheets, for example. The topper 106 further provides a resilient support surface reducing the likelihood of plagiocephely (commonly referred to has “flat head syndrome”), which can develop in infants. Furthermore, due to the ease of installation and removability of the topper 106 and the bottom mat 152, the topper 106 and the bottom mat 152 may be quickly and easily removed from the foldable breathe-through crib mattress (or sleep surface) 100 and washed in a conventional washing machine to remove stains, bacteria, and other matter.
