DETAILED DESCRIPTION OF THE EMBODIMENTS
[0047] Various embodiments of breathable cribs shall be described with reference to
[0048] In general, the present invention is related to a crib design having at least two breathable sides and having a mattress support movable between at least two positions within the crib interior. In general, the American Academy of Pediatrics (AAP) now recommends that infants sleep in the parents' room, close to the parents' bed, but on a separate surface designed for infants, ideally for the first year of life, but at least for the first 6 months. Currently, 3,500 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome (SIDS). The AAP states that sharing a room could cut babies' chance of dying in their sleep by up to 50 percent. The present invention provides a single solution for the first full year room sharing that makes it easier and thus more likely that the infant will sleep in the parents' room. The present invention is different from existing solutions. The present invention is stronger and has breathable sides that protect the infant's limbs from entrapment and defines a safe sleep environment.
[0049] Referring to
[0050] Preferably, the fourth side 108 includes a perimeter structural support system 112 that surrounds and supports a breathable material 114. The perimeter structural support system having a top portion 190, a bottom portion 192 and first and second side portions 194, 196. The breathable material 114 can be any material that allows air to flow through it, including a mesh like material. The breathable material 114 also allows the crib sides to be see-through to see the infant inside. Preferably, the breathable material 114 has an air permeability of between 385 CFM to 1530 CFM and a light permeability of between 47 and 99%.
[0051] The fourth side 108 also includes a lateral support member 116. The lateral support member 116 helps retain the breathable material 114 from bowing out if the infant comes in contact with it. The lateral support member 116 can be placed either inside of the crib 100 or preferably outside of the crib 100. The lateral support member 116 can be any solid material (i.e. wooden, metal, plastic or the like) or a soft material (i.e. hook and loop, zipper or the like). Likewise, the third side 106 includes similar construction to that of the fourth side 108.
[0052] The crib 100 further includes legs 118 that support the crib 100. As shown in
[0053]
[0054] The mattress platform 120 is secured to at least two of the four sides 102, 104, 106, 108 of the crib 100 using any suitable means such as screws, pins, nails or other fastening devices. The mattress platform 120 is movable to at least one other position as shown in
[0055] The lateral support member 116 prevents the breathable material 114 from bowing and allowing the infant to fall through. The breathable material 114 is enclosed between the mattress platform 120 and the lateral support member 116 to prevent the outward deflection of the breathable material 114 away from the mattress platform 120 at an area where an infant rolling or pushing against the breathable material 114 could otherwise create a gap between the mattress platform 120 and the lateral support member 116. The additional support provided by the lateral support member 116 provides additional support to not allow a baby to create a hazardous entrapment gap between the mattress platform 120 and the breathable material 114.
[0056]
[0057]
[0058] As used herein, the term mattress may include any structure disposed within a crib and upon which objects and/or human beings may be placed. In other words, mattress refers to any structure and not just a soft sleeping apparatus. For example, the crib could be configured into a playpen-type structure with a solid hard and/or flat bottom that is, for example, lowered very close to the floor. As such, and as used herein, a crib can be equated to and encompasses the various structures similar to a crib, such as those for containing a small child (e.g., playpens, portable cribs, basinets, convertible cribs, round cribs, or other structures including, for example, spaced-apart side supports that require an apparatus or system such as that described herein).
[0059]
[0060]
[0061] Preferably, the fourth side 408 includes a top support member 416 and a bottom support member 418. The top support member 416 is fixed to the first side 402 and second side 404 such that it is not movable. The bottom support member 418 is movably attached between the first side 402 and second side 404 such that the bottom support member 418 can move between different positions with respect to the top support member 416. As illustrated in
[0062] The breathable material 420 can be any material that allows air to flow through it, including a mesh like material. The breathable material 420 also allows the crib sides to be see through to see the infant inside. The third side 406 also has s similar construction to the fourth side 408. The crib 400 further includes rollers or casters 422 that support the crib 400. The rollers or casters 422 allow the crib to be more easily moved about. One of ordinary skill in the art would also recognize that other supports such as leg designs are possible.
[0063]
[0064]
[0065]
[0066]
[0067]
[0068] In many embodiments, the crib is configured to provide breathable material throughout the crib such that the head of an infant lying in the crib is exposed to mainly breathable material. The breathable material may include any suitable material that provides breathable functionality such as a mesh type material. Breathable functionality refers to the ability of the material to allow air to move effectively there through. As used herein, when air is indicated as moving effectively through a material, it is meant that the material includes openings (e.g., mesh openings, open-framework, spaces between elements thereof, or even those that may not be visually perceivable openings but still allow a breathable function to occur) that do not impede air movement to an extent that would prevent a human being from breathing through (e.g., when a human's respiratory openings (e.g., nose/mouth) are in direct contact with a material) such a material in order to help prevent suffocation and further that such openings are too small to permit an infant to insert a finger or toe there through. For example, such materials may include cotton, silk, polyester, nylon, modal/semi-cellulose based fabrics, etc.
[0069] In one embodiment, the mesh-type material may include a mesh available from Apex Mills, Inc. under the trade designation TA1 Mesh. However, other various similar mesh materials (e.g., mesh material having suitable openings) are available. A Suffocation Hazard Assessment was performed by RAM Consulting (Oak Brook, Ill.) (e.g., the Assessment is further described herein and for which protocol is available from RAM Consulting) on the TAI Mesh resulting in average readings of 1.6 cm H.sub.2O and, for an upper specification limit of 5 cm H.sub.2O, a Z-value of 9.0 was obtained.
[0070] In one example embodiment, the breathable material is a breathable padded mesh-type material (e.g., a padded spacer mesh). Of course, other breathable materials can be used including a single layer mesh. The meshes or other fabrics shown may include designs on the mesh. The meshes or other fabrics may also include a variety of mesh designs and types. It will be recognized that the thickness of the padded mesh material may vary, as well as for other materials described herein. For example, more padding may create a softer more plush effect with slightly different breathability/ventilation properties and more opaqueness (e.g., less light transmissive) whereas less padding may create more breathability and buoyancy with less opaqueness (e.g., more light transmissive). Preferably, the panels described herein are at least somewhat transparent such that at least motion of the child in the crib can be seen.
[0071] The breathable material may be a woven polymeric fiber mesh material that is integrated with or attached to a front and/or back substructure. The front substructure may include larger openings on the front substructure than on the back substructure. In one example embodiment, the padded mesh material may be integrated with or attached to the front and back substructures by weaving the fibers that are provided as part of the pile substructure through the front and back substructure. In another embodiment, the breathable material may be integrated by sewing, or otherwise attaching, the padded mesh material between a front and back substructure or other substructures. That is, in this embodiment the padded mesh material is integrated by attaching to other materials, such as breathable materials or pad materials, to form a multi-layer structure. The multi-layer structure may be, for example, laminated or quilted.
[0072] In one embodiment, for example, the breathable padded mesh material may include a padded spacer mesh available from Apex Mills, Inc. under the trade designation DNB27 Spacer Mesh. However, other various similar padded spacer mesh materials are available.
[0073] In another embodiment, the mesh-type material is a breathable padded mesh material in combination with one or more other material layers. For example, the breathable padded mesh material may be used in combination with one or more layers of other material adjacent to (e.g., one material laid flat against the other) either the front substructure and/or back substructure of the breathable padded mesh material. In various embodiments of such a combination, one or more layers of material may be used adjacent the front substructure, one or more layers of material may be used adjacent the back substructure, or one or more layers of material may be used adjacent the front substructure and the back substructure. For example, such additional layers may be layers of cotton material, knit jersey material, etc. Such additional material layers may provide additional benefits such as, for example, thermal properties with breathability.
[0074] Further, for example, the breathable material when used alone, or in combination with one or more additional layers, may be a breathable material (e.g., a breathable padded mesh material, such as a spacer mesh) that has a suffocation resistance level of less than about 15 cm H.sub.2O, and preferably less than about 5 cm H.sub.2O. Such a suffocation resistance is determined according to the RAM Consulting Virtual Child Suffocation Hazard Assessment Model which is a physical model and testing methodology that quantitatively assesses the potential suffocation hazards posed by various types of materials. The details of this Model are available from RAM Consulting (Oak Brook, Ill.). Further, according to this Model, Z-values are determined that are statistical measurement tools that describe and predict product performance in relation to its specification limit (e.g., such as those described below). For example, the suffocation resistance limit of 5 cm H.sub.2O is an upper specification limit for materials or products that foreseeably are used and/or intended for young infants with high accessibility; and further, the suffocation resistance limit of about 15 cm H.sub.2O is an upper specification limit for other materials or products (e.g., those for toddlers). A Z-value of 4.0 or greater with the corresponding upper specification limit for each applicable testing technique is required for a product to be classified as a very low suffocation risk. The details regarding the determination of Z-values are available from RAM Consulting (Oak Brook, Ill.).
[0075] Suffocation Hazard Assessment was performed by RAM Consulting (Oak Brook, Ill.) on various configurations using the breathable padded mesh material available from Apex Mills, Inc. under the trade designation DNB27 Spacer Mesh.
[0076] 1 Configuration 1: Single Layer of Padded Spacer Mesh Configuration 2: Layer 1: Padded Spacer Mesh Layer 2: Cotton Configuration 3: Layer 1: Knit Jersey Layer 2: Padded Spacer Mesh Layer 3: Cotton Configuration 4: Layer 1: Cotton Layer 2: Padded Spacer Mesh Layer 3: Cotton Configuration 5: Layer 1: Knit Jersey Layer 2: Padded Spacer Mesh Layer 3: Knit Jersey Configuration 6: Layer 1: Padded Spacer Mesh Layer 2: Flannel Fabrics tested: Knit Jersey Manufacturer: NATEX Content: 50% Polyester/50% Cotton Knit Jersey Style #: INT Cotton Manufacturer: SOUTHERN BELLE Content: 100% Cotton Style #: L93N67 Flannel Manufacturer: QUILTERS CORNER Content: 100% Cotton Style #: RN41324.
[0077] A screening was performed on all configurations in both a dry and wet state. The spacer padded mesh when layered with fabrics resulted in a satisfactory reading based on values in cm H.sub.2O, wherein the specification upper limit for products young children are intended to lie on is equal to 5 cm H.sub.2O (e.g., mattress pads or items young infants are intended to have their face on) and wherein the specification for products young children are not intended to lie on is equal to 15 cm H.sub.2O.
[0078] Four individual readings were performed with an average being determined. Dry state readings did not register, thus presenting very low hazard when the configurations were dry (i.e., under the 5 cm H.sub.2O specification limit). In the wet state (after application of 8 ml of sprayed on water), the average readings for the configurations were between 4.6 cm H.sub.2O and 6.2 cm H.sub.2O.
[0079] For the individual single layer of spacer padded mesh, average readings of 1.7 cm H.sub.2O were taken. Further, for an upper specification limit of 5 cm H.sub.2O, a Z-value of 9.5 was obtained.
[0080] The air permeability of breathable materials may allow the breathable material to be layered with other breathable material to create a layered breathable material, while still maintaining air permeability (CFM).
[0081] Testing was conducted by Bureau Veritas in accordance with ASTM D737 standards to determine the air permeability (CFM) of a single layer of textile materials. Additionally, various combinations of layered materials were also tested to determine air permeability. For example, a single layer of breathable material with a thickness of 0.13 inches provided an air permeability of 1013.1 CFM. Adjusting the properties (e.g., thickness, weave pattern, etc.) of the single layer of a breathable material may allow the air permeability to achieve an air permeability of at least 1250 CFM. Adjusting the properties (e.g., thickness, weave pattern, etc.) of the layered breathable material may allow the air permeability to achieve an air permeability of at least 900 CFM.
[0082] The breathability of the breathable material 114 of crib 100 can be measured using a variety of methodologies, including air permeability, mesh coverage (both location and cover factor measurement via light microscopy), light permeability as measured by photodetector, spectrophotometer or by transmittance or blocking of ultraviolet radiation, or other suitable tests. Preferably, the breathable material 114 has an air permeability of between 385 CFM to 1530 CFM. Of course, the higher the air permeability the more breathable the material is. Preferably, the breathable material 114 has a mesh coverage of between 32% and 91%. Mesh coverage is measure of the holes versus material in a mesh material. Preferably, the breathable material 114 has a light permeability by photodetector of between 47% and 99%, by spectrophotometer of between 4 and 71%, and by ultraviolet radiation of between 47% and 100%. The tested samples may have one or more layers that compose the breathable material 114 and may or may not be padded. The below chart illustrates tests performed on various samples of materials that could comprise the breathable material 114:
