BACKGROUND
1. Field
This application relates to climate control, and more specifically, to climate controlled beds (e.g., adjustable beds, stationary beds, etc.) assemblies and other seating assemblies.
2. Description of the Related Art
Temperature-conditioned and/or ambient air for environmental control of living or working space is typically provided to relatively extensive areas, such as entire buildings, selected offices, suites of rooms within a building or the like. In the case of enclosed areas, such as homes, offices, libraries and the like, the interior space is typically cooled or heated as a unit. There are many situations, however, in which more selective or restrictive air temperature modification is desirable. For example, it is often desirable to provide an individualized climate control for a bed or other seating device so that desired heating or cooling can be achieved. For example, a bed situated within a hot, poorly-ventilated environment can be uncomfortable to the occupant. Furthermore, even with normal air-conditioning, on a hot day, the bed occupant's back and other pressure points may remain sweaty while lying down. In the winter time, it is highly desirable to have the ability to quickly warm the bed of the occupant to facilitate the occupant's comfort, especially where heating units are unlikely to warm the indoor space as quickly. Therefore, a need exists to provide improved designs of adjustable (e.g., reclinable) and/or stationary climate-controlled bed assemblies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
This application is generally directed to climate control systems for beds or other seating assemblies. The climate control system and the various systems and features associated with it are described herein in the context of bed assemblies (e.g., air chamber beds, adjustable beds, inner-spring beds, spring-free beds, memory foam beds, full foam beds, hospital beds, other medical beds, futons, sofas, reclining chairs, etc.) because they have particular utility in that context. However, the climate control system and the methods described herein, as well as their various systems and features, can be used in other contexts as well, such as, for example, but without limitation, seat assemblies for automobiles, trains, planes, motorcycles, buses, other types of vehicles, wheelchairs, other types of medical chairs, beds and seating assemblies, sofas, task chairs, office chairs, other types of chairs and/or the like.
The various embodiments described and illustrated herein, and equivalents thereof, generally disclose improved devices, assemblies and methods for supplying ambient and/or thermally conditioned air or other fluids to one or more portions of a bed assembly. As discussed in greater detail herein, as a result of such embodiments, air or other fluids can be conveyed to and/or from an occupant in a more efficient manner. For example, the various embodiments disclosed herein can provide simpler climate controlled seating assemblies that provide one or more operational benefits or advantages (e.g., quieter operation, operation with less vibration, more streamlined configurations that are capable of accommodating fixed and adjustable assemblies, etc.). In addition, the embodiments disclosed herein can provide improved fluid movement to, through and/or from a climate controlled bed or seating assembly.
With reference to the perspective views of FIGS. 1 and 2, a climate controlled bed 10 can be configured to be adjustable or otherwise adapted to be selectively reclined or otherwise moved. As shown, the bed 10 can comprise one or more upper portions 20 (e.g., a mattress) that are sized, shaped and otherwise configured to support one or more occupants. The mattress 20 or other upper portion can comprise a standard shape and/or size (e.g., double, queen, king, etc.). However, in other embodiments, the mattress (and thus the corresponding bed assembly on which the mattress is situated) can include a non-standard size, shape and/or other configuration, as desired or required by a particular application or use.
With continued reference to FIGS. 1 and 2, the upper portion 20 or mattress can be designed to be removably or permanently positioned on top of a lower portion L or foundation of the bed assembly 10. In the illustrated embodiment, the lower portion L comprises a bottom or primary foundation 40 (or lower support member) and a top or secondary foundation 60 (e.g., intermediate support member, interlay or inlay component, etc.). The terms secondary foundation, intermediate support member, interlay, interlay component, inlay and inlay component are used interchangeably herein. As discussed in greater detail herein, the lower support member (e.g., foundation) 40 and the intermediate support member (e.g., inlay component) 60 can be attached or otherwise secured to each other (e.g., removably or permanently). The members 40, 60 can be held relative to each other using one or more attachment devices or methods, such as, for example, stitching, zippers, hook-and-loop connections, buttons, straps, bands, other fasteners, adhesives and/or the like. In other embodiments, the lower portion 40 can include more or fewer members or components, as desired or required.
As illustrated in FIG. 2, the adjustable bed 10 can be selectively moved (e.g., reclined) such that one portion of the assembly is angled relative to one or more other portions of the assembly. The bed 10 can be angled, reclined and/or otherwise moved with the assistance of one or more motors, actuators and/or other mechanical, electromechanical, pneumatic or other type of device.
With reference to FIG. 3, the lower support member or foundation (e.g., primary foundation) 40 can comprise a plurality of segmented sections 42 that are configured to move relative to each other to accommodate movement of the adjustable bed during use. For example, the assembly 10 of FIGS. 1 and 2 comprises a lower support member 40 having a total of seven segmented sections 42. However, in other embodiments, the number of sections 42 can be greater or less than seven (e.g., 2, 3, 4, 5, 6, 8, 9, 10, more than 10, etc.), as desired or required. These segmented sections 42 provide the bed assembly 10 with the necessary flexibility and/or bendability as the adjustable bed is moved between different positions or configurations during use. Adjacent segmented sections 42 can be separated by gaps, spaces or other joints 44 that are configured to permit one section 42 to angle or other move relative to the adjacent section 42. The amount of permitted movement between adjacent sections 42 can be selected based on one or more factors, such as, for example, the size of the sections, the size of the bed assembly 10, the amount flexibility or bendability required or desired for the assembly and/or the like.
With continued reference to FIG. 3, the sections 42 that comprise the lower support member 40 can include one or more openings or passages 48. Air or other fluids delivered by one or more fluid modules (not shown in FIG. 3) can be selectively delivered through the passages 48 to transfer such air or other fluids from the fluid modules, at least partially through the lower portion L and/or the upper portion 20 of the bed assembly 10, e.g., toward one or more occupants positioned on the assembly.
A fluid module can include a fluid transfer device (e.g., blower, fan, etc.), a thermal conditioning device (e.g., a Peltier device, other thermoelectric device or TED, a convective heater, a heat pump, another type of heating and/or cooling device or component, etc.), a dehumidifier and/or any other type of conditioning device. Some embodiments of a fluid module comprise one or more conduits to place the various components of the fluid module and other portions of the bed 10 in fluid communication with each other and/or the like. The various components of a fluid module can be included within a single housing or can be separated from one another but fluidly connected (e.g., using one or more conduits). Accordingly, thermally or environmentally conditioned air (and/or ventilated or ambient air) can be directed toward the lower portion L and/or the upper portion 20 by the one or more fluid modules. In any of the embodiments disclosed herein, or equivalents thereof, the fluid module can include a heating, cooling and/or other conditioning (e.g., temperature, humidity, etc.) device that is not a thermoelectric device. For example, such a conditioning device can include a convective heater, a heat pump, a dehumidifier and/or the like.

In some embodiments, one or more fluid modules are fixedly or removably secured to the rear surface of the lower support member 40. For example, a fluid module can be attached to a rear surface (e.g., the surface that generally faces toward the ground when the bed 10 is generally horizontally positioned) and/or to the segmented section 42 so as to generally or completely align an outlet of the fluid module to the fluid passage or opening 48. Thus, air or other fluid can be selectively delivered through the lower support member 40 (e.g., toward and through the intermediate support member 60 and the upper support member or mattress 20 of the bed assembly 10). In some embodiments, each fluid passage or opening 48 is placed in fluid communication with at least one fluid module. In some embodiments, a single fluid module can be configured to deliver air or other fluid to two or more passages or openings 48 of the lower support member 40. Further, in some arrangements, two or more fluid modules can be placed in fluid communication with a single fluid passage 48, as desired or required. In other embodiments, however, one or more fluid modules can be positioned, at least partially, within an intermediate layer or interlay of a climate controlled bed or other seating assembly.
The fluid modules can be secured directly to the rear surface of the lower support member 40 (e.g., to one or more of the segmented sections 42). Alternatively, the fluid modules can be attached to another portion of the bed's foundation or another portion of the bed assembly (e.g., a frame that holds or otherwise supports the lower support member 40, an interlay or inlay component, etc.). The fluid modules can be powered using any one of a number of power sources, such as, for example, a power cord (e.g., in electrical communication with an AC plug or power generator), one or more batteries and/or the like.
One embodiment of an intermediate support member or interlay 60 is illustrated in FIG. 4. As shown, the intermediate support member or interlay 60 can include one or more slotted openings or cavities 64 formed therein. In some embodiments, the intermediate support member 60 can be initially manufactured with the slotted openings or cavities 64 (e.g., using injection molding, other molding techniques, etc.). Alternatively, however, such openings 64 can be formed after the main body of the intermediate support member 60 has been manufactured (e.g., by selectively cutting or otherwise removing certain portions of the member 60). Regardless of how they are formed or created, the slotted openings or cavities 64 can be shaped, sized and/or otherwise configured to permit air or other fluids to pass from the fluid modules, through the lower support L and/or the upper support (e.g., mattress) 20 while the bed assembly is in any reclined position and/or while the position of the bed assembly is being modified.
With continued reference to FIG. 4, the slotted openings 64 of the intermediate support member 60 can be configured to pass only partially through a vertical section (e.g., generally perpendicular to the ground when the bed 10 is generally horizontally positioned) of the member 60. As shown, a lower section 62 of the intermediate support member or interlay 60 (which, in some embodiments, comprises one or more slotted openings 64) can be selectively covered by an upper, generally continuous section 68. The upper section 68 can comprise open foam and/or another type of air-permeable or partially air-permeable material to allow air or other fluid to freely pass from the slotted opening 64 to the top of the intermediate support member 60 via the upper section 68. In other embodiments, however, the intermediate support member or inlay component 60 comprises one or more slotted openings, passages or other cavities 64 that extend through the entire vertical portion of the member 60.
As depicted in the arrangement of FIG. 4, the interlay component 60 can include one or more slots 65 (e.g., cutouts, hinges, perforations, etc.) to facilitate bending of the component 60 when the bed assembly 10 is in use. In certain embodiments, the intermediate support member or inlay 60 (and/or the lower support member 40 to which the member 60 is fixedly or removably attached) comprises one or more bars, rails, guides, fasteners or other retention assemblies or members 66. Such retention assemblies 66 can help maintain a proper orientation between the upper portion or mattress 20 and the lower support L (e.g., the intermediate support member or interlay component 60, the lower support member 40, etc.) as the position of the bed is modified (e.g., reclined, otherwise moved, etc.), during use. However, one or more other types of retention members (e.g., straps, fasteners, etc.) can be used to hold a desired orientation between the upper portion 20 and the lower portion L while the adjustable bed is in use, either in addition to or in lieu of the rails or retention members 66 illustrated herein.
FIG. 5 illustrates a perspective top view of one embodiment of the intermediate support member, inlay or interlay component 60 positioned and secured relative to a foundation 40. As shown, the slotted openings or cavities 64 of the intermediate support member 60 can generally align with (e.g., at least longitudinally) one or more of the fluid passages 48 of the lower support member or foundation 40. Thus, a slotted opening 64 can be in fluid communication with a fluid passage 48 and the fluid module to which the fluid passage is fluidly coupled. Accordingly, air or other fluid delivered by the fluid modules can be advantageously transferred to one or more of the slotted openings or passages 64 of the intermediate support member, interlay or inlay 60.
With continued reference to FIG. 5, and as noted above, the intermediate support member 60 can comprise an air permeable upper section 68 to effectively cover the slotted openings or passages 64 of the member 60. As shown schematically in FIG. 5, air A or other fluid can pass from the passages 64 through the upper section 68 and exit toward the top of the intermediate support member 60 (e.g., to and through one or more fluid openings or passages of the upper portion or mattress 20. For example, the mattress 20 (see, for example, FIGS. 19A, 19B and 20, and/or various embodiments of a mattress or upper portion disclosed in the patents and publications incorporated by reference herein) can include one or more fluid openings that pass at least partially through the mattress's internal structure. For example, one or more fluid passages or openings can extend from the bottom of the mattress or upper portion 20 to one or more fluid distribution members (e.g., spacer fabrics, spacer materials, etc.) located at or near the top of the upper portion.
The upper portion can comprise one or more materials to provide the desired or required firmness, feel, comfort and/or other characteristics to the bed assembly 10. For example, the bed 10 can include one or more layers of foam (e.g., viscoelastic foam, polyurethane foam, coconut foam, memory foam, other thermoplastics or cushioning materials and/or the like), latex, other thermoplastic materials, pillow layers, other comfort layers and/or the like. In some embodiments, the bed comprises springs (e.g., coil springs, air springs, etc.), air or fluid tubes or containers and/or any other component, device or feature.
FIG. 6 illustrates different top views of an internal passage 24 of the upper portion or mattress 20 as it traverses along, and relates to the slotted openings or passages 64 of the intermediate support member 60. As shown, in some configurations, the internal passage 24 generally aligns with the openings or passages 64. For clarity, only the internal passage 24 (e.g., the inlet of the internal passage at or near the bottom of the upper portion 20) is illustrated in FIG. 6. For additional clarity, the air permeable upper section or cover 68 is also not shown in FIG. 6. As shown, the location of the internal passage 24 can vary as the position of the adjustable bed assembly 10 is modified during use (e.g., as the bed is reclined or otherwise manipulated by an occupant). In some embodiments, the position of one or more internal passages 24 of the mattress or upper portion 20 can vary over a specific range R during use. In some embodiments, the range R is between about 1 to 12 inches (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 inches, values between the foregoing, etc.). However, in other embodiments, the range R can be less than about 1 inch or greater than about 12 inches (e.g., 14, 16, 18, 24 inches, more than 24 inches, etc.), as desired or required.
Accordingly, the internal passage(s) 24 of the upper portion or mattress 20 can remain in fluid communication with the slotted opening or cavity 64 of the intermediate support member and the fluid passage or opening 48 of the lower support member 40. Thus, air or other fluid can be continuously delivered to the upper portion 20 of the bed assembly 10 while the adjustable bed is in use (e.g., even while the bed is being adjusted).
Additional Interlay or Inlay Embodiments
In some embodiments, as illustrated in FIGS. 7A and 7B, one or more intermediate layers or inlay components 160, 160′ can be strategically positioned between an upper portion or mattress 120, 120′ and a lower portion or foundation 140, 140′. In some embodiments, such an intermediate layer 160, 160′ is incorporated into any type of stationary bed 110 (e.g., FIG. 7A), adjustable, reclinable or otherwise movable bed 110′ (FIG. 7B) and/or any other type of climate controlled seating assembly (e.g., vehicle seat, office chair, sofa, other type of seat or chair, etc.). In any of the embodiments disclosed herein, the inlay or interlay component(s) can be attached to one or more other portions or components of the bed assembly (e.g., the adjacent foundation, other frame, mattress or upper portion, etc.) or it can be separate and unattached to other portions or components of the assembly, as desired or required.
In some embodiments, as disclosed herein, an intermediate layer comprises one or more fluid channels or ducts (e.g., for receiving and moving air, other gases and/or other fluids to specific locations of the bed or other seating assembly), spaces configured to receive and house a fluid module (e.g., a blower or other fluid transfer device, a thermoelectric device, convective heater and/or any other heating, cooling or ventilation device, etc.), wiring, wire harnesses and/or other electrical components, sensors and/or the like. In any of the embodiments disclosed herein, a fluid module can comprise one or more portions. For example, in some arrangements, the blower, fan or other fluid transfer device can be included within a single housing or enclosure with one or more other components (e.g., a thermoelectric device, a convective heater, another type of thermal conditioning device, a controller, one or more sensors, etc.). Alternatively, however, two or more components of a fluid transfer and conditioning system can be separated (e.g., not positioned within a single housing or enclosure). For instance, the blower or fluid transfer device can be in a first housing or enclosure, while the thermal conditioning device (e.g., thermoelectric device, convective heater, etc.) is set apart from the blower. In such embodiments, the components can be placed in fluid communication with one another via one or more conduits, channels, ducts, passages and/or the like, as required.
The use of an intermediate layer in a climate controlled bed or other seating assembly can offer one or more advantages related to the manufacture and/or use of the bed or other seating assembly. For example, an intermediate layer that houses a fluid module, fluid ducts or channels and/or other components of a climate or environmental conditioning system can simplify the design, manufacture, assembly, transport and/or other aspects of the environmentally-conditioned bed or other seating assembly. Further, the intermediate layer or interlay component can be used to advantageously house (e.g., at least partially) the fluid module, ducts or fluid channels, wire harnesses, wiring, power supplies, controllers, sensors and/or other components without the need for install such items in adjacent portions of the bed or other seating assembly (e.g., lower support, upper portion or mattress, etc.). In some embodiments, such configurations can permit a climate controlled bed assembly with limited space (e.g., limited space below the mattress or upper member, limited space around or near the assembly, etc.) to accommodate one or more fluid modules. In addition, such configurations can reduce the overall noise and/or vibration associated with operating the fluid modules (e.g., blower or other fluid transfer device).
FIG. 7A illustrates one embodiment of a fixed climate controlled bed assembly 110 comprising an intermediate, interlay or inlay layer or component 160 generally positioned between the lower support 140 (e.g., slotted or fixed foundation, box spring, other frame or support portion, etc.) and an upper portion (e.g., a mattress, upper cushion, etc.). As noted above, the terms intermediate layer, interlay layer or interlay, inlay layer or inlay are used interchangeably herein. Alternatively, as shown in the embodiment of FIG. 7B, an intermediate layer 160′ can be similarly incorporated into an adjustable or otherwise movable bed assembly 110′. One or more features of the adjustable bed discussed with reference to FIGS. 1-6 can be incorporated into other adjustable beds or seating assemblies disclosed herein. Such intermediate or inlay layers can be included in any other type of bed or seating assembly or component, for example, a sofa, a chair, a seat, a futon, a bed topper and/or the like.
In any of the embodiments disclosed herein, the intermediate or inlay layer includes one or more fluid channels configured to permit fluid (e.g., heated, cooled or ventilated fluid discharged by a fluid module, waste fluid, etc.). Accordingly, such channels or other passages are in fluid communication with one or more fluid modules. In any of the embodiments disclosed herein, a fluid module can include a fluid transfer device (e.g., fan or blower), a thermal conditioning device (e.g., a thermoelectric device, a convective heater, another type of fluid heating or cooling device, etc.), one or more sensors (e.g., temperature sensors, humidity sensors, condensation sensors, etc.), controllers and/or the like. In some embodiments, the blower or other fluid transfer device is included within a single housing as a thermal conditioning device and/or one or more other components of the module. Alternatively, however, the blower or other fluid transfer device can be separated from one or more other components of the fluid module (e.g., a thermoelectric device, convective heater or other thermal conditioning device). In such embodiments, one or more ducts, conduits or other fluid lines can be used to deliver air or other fluid from the fluid transfer device to, near or past the thermal conditioning device and/or other components of the fluid module.
Further, as noted and illustrated in some of the embodiments disclosed herein, the intermediate layer or inlay can be shaped, sized, designed and otherwise configured to accommodate one or more fluid modules directly therein. Such a configuration can provide one or more benefits and other advantages to the climate controlled seating assembly, such as, for example, space saving advantages, simplification of the assembly's overall design, quieter, smoother and/or otherwise more enhanced or improved operation of the system (e.g., reduced noise and/or vibration created by the operating fluid modules, better fluid transfer to, through and away from the assembly, etc.) and/or the like. Alternatively, however, one or more fluid modules are not located within or near the intermediate layer or inlay, requiring fluid from such fluid modules to be routed to one or more inlets of the channel(s) of the intermediate layer or inlay. Regardless of its exact orientation, configuration and overall design, the intermediate layer or inlay can receive and strategically route inlet air and/or air discharged by one or more fluid modules (e.g., heated, cooled or ventilated fluid intended to be delivered through one or more openings of the adjacent mattress or upper layer toward a seated occupant). The channels of the intermediate layer or inlay can also be used to receive and strategically route other fluid streams created by the fluid modules. For example, the inlay can comprise one or more channels that receive and route to select portions of the inlay, and thus the seating assembly, waste air created by one or more thermoelectric devices or other thermal conditioning devices of the assembly's climate control system. As discussed in greater detail herein, the intermediate layer or inlay can also be used to strategically and advantageously accommodate one or more wire harnesses for placing the fluid modules and/or other electric components of the system in power and/or data communication with a power supply, controller and/or the like.
According to some embodiments, the fluid channels of the intermediate layer or inlay of a bed or other seating assembly are configured to selectively route thermally conditioned (and/or ventilated) air or other fluid to one or more fluid inlets of the adjacent mattress or upper portion of the bed or other seating assembly. Accordingly, fluid can be delivered through the mattress or other upper portion of the assembly and toward one or more seated occupants.
FIG. 8 illustrates a front perspective view of a climate controlled bed (e.g., a fixed bed) 110 that comprises one or more intermediate layer or inlays. In the depicted embodiment, for example, there are two separate inlay components 160 positioned between the mattress or upper portion 120 and the foundation or lower portion 140 of the bed. As with other climate controlled bed configurations disclosed herein, the assembly 110 of FIG. 8 includes two equally sized or substantially equally sized inlay components 160, each of which is sized, shaped and configured to span across half or substantially half of the bed's surface area. For example, each inlay component 160 can cover the left or right portion of the bed (e.g., the area associated with one of the occupants of a bed, futon, sofa or other seating assembly). In other embodiments, however, the intermediate layer or inlay 160 can include more (e.g., three, four, more than four, etc.) or fewer (e.g., only one) components, depending on the size of the bed or other seating assembly and/or as otherwise desired or required.
One embodiment of an intermediate layer, interlay or inlay 160, 160′ configured for use in a climate controlled seating assembly (such as the fixed or adjustable beds of FIGS. 7A and 7B, respectively) is illustrated in FIG. 9. As shown, the inlay 160, 160′ (or a component thereof) can comprise one or more fluid modules 100. Therefore, for a bed assembly that includes two inlay components, such as the one illustrated in FIG. 8, a total of four fluid modules are used. The depicted embodiment of the inlay component comprises a total of two fluid modules, spaced apart from one another. In other embodiments, the quantity, location, orientation, spacing and/or other details regarding the fluid modules can vary, as desired or required. For example, an intermediate layer or inlay can include fewer (e.g., one) or more (e.g., three, four or more) fluid modules, depending on the size of the bed or other seating assembly, the desired environmental conditioning and/or one or more other factors or considerations.
With continued reference to FIG. 9, the intermediate layer or inlay 160, 160′ can include one or more inlet channels 122, 124 through which ambient air or other fluid is drawn toward the intake or inlet of the module's blower, fan or other fluid transfer device. In the illustrated embodiment, the inlet channels 122, 124 extend laterally from one side end of the intermediate layer 160, 160′ to the other end. In such an arrangement, therefore, at least part of the air that is transferred by the fluid modules is drawn toward the inlet of the fluid module from both the left and right sides of the layer 160, 160′. In other embodiments, however, the inlet channels can be routed along a different portion of the intermediate layer or inlay 160, 160′ (e.g., the head-side or foot-side of the layer), either in lieu of or in additional to the sides, as desired or required. In the various embodiments disclosed herein, the channels or passages of the interlay or inlay components comprise a generally rectangular cross-sectional shape. However, the cross-sectional shape of the channels can vary (e.g., semi-circular, partially oval or circular, triangular, other polygonal, irregular, etc.), as desired or required. Further, in any of the embodiments disclosed herein, one or more of the channels can include a lining, coating and/or other feature thereon (e.g., to improve air impermeability, reduce head loss and/or for any reason, purpose or goal).
In some embodiments, and for any of the bed or other seating assemblies disclosed herein, only a portion of the air that is delivered to the fluid modules originates from the inlet channels of the inlay or interlay component 160, 160′. For example, at least some or even a majority of the volume of inlet air that is transferred by the fluid modules can come from the space underneath the interlay component (e.g., from the foundation or other area below the interlay component and through the windows or openings 182 along the rear side of the inlay component). In fact, in some embodiments, the inlet channels 122, 124 of the inlay are configured to serve merely as supplemental conduits of inlet air. In some arrangements, one reason for this is because the edges of the interlay inlet channels can become blocked, at least partially, by blankets, sheets or other portions of a bed or other items placed adjacent to the bed (e.g., chests, other furniture, etc.). Thus, the bottom of the bed assembly can provide a more reliable and consistent source of inlet air to the fluid modules.
With continued reference to FIG. 9, the interlay or interlay component 160, 160′ comprises one or more recesses that are sized, shaped and otherwise configured to accommodate fluid modules. Such recesses or portions of the interlay component are advantageously designed so that when a fluid module is positioned therein, the inlets of the fluid modules are generally aligned and/or otherwise placed in fluid communication with the inlet channels 122, 124 of the interlay and/or other inlet openings (e.g., windows or other accessways 182 along the rear side of the interlay). In any of the embodiments disclosed herein, the inlay or interlay components can comprise one or more flexible, rigid and/or semi-rigid materials, such as, for example, foam (e.g., open cell foam, closed cell foam, etc.), other plastic materials, metals, alloys, other composite or natural materials, etc.). For example, the interlay can be configured to be generally flexible within a desired range for use in adjustable beds or other movable seating assemblies. In addition, the interlay components can be air permeable (partially or completely) or air impermeable, as desired or required.
According to some embodiments, as illustrated in FIG. 11, the fluid modules 100 that are positioned within the interlay component 160, 160′ are provided as part of a larger module assembly. For example, the depicted assembly comprises a fluid module 100 (e.g., blower or other fluid transfer device, thermoelectric device, convective heater or other thermal or environmental conditioning device, etc.) and a duct or other fluid conduit 108 in fluid communication with an outlet (e.g., the waste outlet) of the module. The module assembly can also include one or more guides or separation members 102, 104 that are configured to provide a necessary or desired clearance between the fluid module and the bottom of the interlay component once the assembly has been properly positioned within the interlay and the interlay has been placed between a foundation and a mattress or other upper portion. The module assembly illustrated in FIG. 11 can be sized, shaped and otherwise configured to be placed within a corresponding module recess, channel recess and/or other portion of the interlay component, as shown in FIG. 9. However, in other embodiments, one or more fluid modules 100 can be positioned directly into the inlay or interlay component 160, 160′.
Regardless of their exact design and other details, fluid modules 100 having a waste stream (e.g., such as fluid modules that comprise one or more thermoelectric devices or similar heating or cooling devices) can be configured to discharge such a waste stream in one or more waste conduits or channels 112, 114 of the inlay or interlay component. As illustrated in the embodiment of FIG. 9, the waste streams of the fluid modules 100 are directed to the head-end and foot-end of the bed via corresponding waste channels 112, 114. In other embodiments, however, the waste channels are directed to one or more other locations of the bed or other seating assembly (e.g., one or more of the side edges, only the head-end, only the foot-end, etc.), as desired or required.
With continued reference to FIG. 9, the inlay or interlay component 160, 160′ can comprise one or more slots 132, gaps, recesses or other spaces configured to accommodate wire harnesses, wires, other electrical connections, sensors, struts or other structural reinforcing members and/or any other device or component. Such openings 132 can allow for wire harnesses, other electrical connectors and/or any other device or member to be neatly and discretely positioned in the inlay component (e.g., to provide power to the fluid modules, to place the fluid modules, components thereof and/or other components, such as, sensors, controllers and/or the like in data communication with one another or with other portions of the assembly's climate control system, etc.).
According to some embodiments, the channels, wire harness slots, fluid module recesses and/or other openings of the inlay component 160, 160′ are manufactured into the desired shape using molding techniques (e.g., injection molding). Alternatively, however, such openings can be created by selectively removing portions of a base material (e.g., larger foam block or layer). In other embodiments, one or more layers or portions can be selectively attached to a base layer 161 so as to create the channels 122, 124, 112, 114, recesses, slots 132 and/or other openings within the inlay component, as desired or required. For example, smaller foam components can be secured to one or more base foam layers 161 using adhesives, fasteners and/or any other type of connection method or device.
As illustrated in FIGS. 9 and 10A, one or more coverings or outer layers 180 can be positioned at least partially along the outside of the inlay or interlay component 160, 160′. In the depicted embodiment, a generally air impermeable or partially air impermeable layer 184 (e.g., fabric, coating, etc.) is positioned along the lower side of the inlay component. In some arrangements, such a layer 184 comprises an anti-skid or anti-slip layer that helps to maintain the position of the inlay component relative to the foundation on which it is positioned after assembly and during use. As noted herein, the layer can include one or more windows or other openings 182 that are aligned (at least partially) with the fluid modules to advantageously permit inlet air to be transferred to the fluid modules from an area below the inlay component 160, 160′ (e.g., within or near the foundation).
With reference to the top view of the inlay component illustrated in FIG. 10B, the top surface 188 of the component 160, 160′ can also include one or more non-skid layers to help maintain the position of the inlay component relative to the mattress or upper portion of the bed assembly. Further, the discharge end 190 of each of the fluid modules 100 included within the inlay component can be directed to corresponding outlets 190 that extend to or near (or in some embodiments, through and above) the top of the inlay component (e.g., through one or more layers or other coverings). In some embodiments, such outlets 190 are oriented so as to generally align with internal passages of the adjacent mattress or other upper portion of the bed assembly (see, e.g., FIGS. 19A, 19B and 20). Accordingly, air or other fluid discharged by the fluid modules of the inlay component 160 160′ can be advantageously delivered through fluid passages of the mattress and toward the top of the bed assembly (e.g., toward one or more seated occupants through one or more fluid distribution members or portions located along or near the top of the mattress). In the depicted arrangements, the outlets are generally aligned along a longitudinal axis 192 of the inlay. However, in other embodiments, two or more of the outlets can be offset form each other, as desired or required.
FIG. 12 illustrates a top perspective view of two intermediate layers, inlay components or interlay components 160, 160′ positioned next to one another in a side-by-side orientation. In the depicted embodiment, the inlay components are sized, shaped and otherwise configured to rest on a single foundation or lower portion 140 of a fixed bed, an adjustable bed or any other seating assembly. In other embodiments, the quantity, size, orientation and/or other details of the inlays 160, 160′, the foundation 140 and/or any other component of the bed assembly can vary, as desired or required by a particular design or application.
FIG. 13 illustrates one embodiment of a window or other opening 182 along the back or rear side (e.g., bottom, when the inlay is positioned on a bed assembly) 184 of an inlay component 160, 160′. As shown, the window 182 comprises a layer of mesh and/or one or more other air permeable materials or configurations to permit air or other fluid to freely flow from the area beneath the inlay 160, 160′ to the inlet of the fluid module positioned within the inlay component. According to some embodiments, the layer or covering along the rear side of the inlay adjacent the window or opening 182 can be completely or partially air impermeable. For example, the layer can comprise a non-skid or anti-skid material to prevent or reduce the likelihood of relative movement between the interlay 160, 160′ and the adjacent foundation or frame when the bed assembly is properly assembled and in use. In the depicted embodiments, the windows or other openings along the rear surface of the inlay component are generally rectangular. However, in other arrangements, the shape, size, spacing, orientation or other details related to the windows can vary, as desired or required. For example, the windows 182 can comprise a generally circular, oval, other polygonal (e.g., triangular, pentagonal, hexagonal, etc.), irregular and/or any other shape. For any of the embodiments disclosed herein, any layer or other covering that is positioned completely or partially around a interlay, inlay or intermediate layer or component can be configured to include an air permeable or partially air permeable portion (e.g., permeable fabric or other layer, mesh or other layer comprising one or more fluid openings or passages, etc.) at locations where the channels (e.g., inlet channels, waste channels, etc.) terminate along the ends or edges of the inlay. Such a configuration can allow air to freely enter and/or exit the channels of the inlay.
One embodiment of a foundation or lower portion 140 for a bed assembly (e.g., a non-adjustable bed) is illustrated in FIG. 14. As shown, the foundation 140 can comprise a unitary structure that is sized, shaped and otherwise configured to span across the entire area or substantially the entire area of the climate controlled bed assembly. Alternatively, however, the foundation 140 can include two or more components which, when secured to one another or placed in proximity to one another, support the inlay component(s), mattress or upper portion and any other components of the bed assembly. With continued reference to FIG. 14, the top surface 141 of the foundation 140 can include one or more openings 148. In some embodiments, such openings 148 are sized, shaped, located and otherwise configured to align or substantially align with adjacent windows or other openings 182 along the rear surface of the inlay 160, 160′. Accordingly, air or other fluid can be drawn into the fluid modules located within or near the inlay components from the area within, below and/or near the foundation 140.
FIG. 15 illustrates a rear, perspective view of a foundation or lower portion 140′ configured to be used in an adjustable climate controlled bed assembly. As shown, the foundation 140′ can include one or more slots, gaps or spaces 144 that separate adjacent portions or sections 142 of the foundation. In some embodiments, adjacent sections 142 are connected to each other using one or more fasteners (e.g., straps, belts, wires, mechanical fasteners, etc.) that provide the required or desired flexibility to the foundation (e.g., by allowing relative rotation of adjacent sections or portions). Accordingly, the adjustable bed can be permitted to rotate during use as a user changes the angle of the bed. In the illustrated embodiment, the foundation 140′ comprises a total of five sections 142, some of which vary in shape. In other arrangements, however, the number, length, spacing, relative angular flexibility and/or characteristics of the adjustable foundation can vary, as desired or required by a particular application or use. The use of a slotted foundation, such as the one illustrated in FIG. 15, can facilitate the delivery of air other fluid from the area within or below the foundation to the fluid modules positioned within one or more interlay or inlay components. For example, the slots or openings of the foundation can be located along or near adjacent windows or openings 182 along the lower surface of an inlay so as to provide access to the corresponding fluid module intake. Such slots can either replace or supplement other openings within a foundation (see, for example, the dedicated openings 148 of the foundation of FIG. 14).
FIGS. 16A and 16B illustrate different views of another embodiment of an intermediate layer or inlay component 260, 260′ configured for use in a climate controlled bed or other seating assembly. As with other inlay configurations disclosed herein, the depicted inlay component 260, 260′ can be used either in fixed or adjustable bed assemblies. In the illustrated embodiment, the inlay component 260, 260′ comprises two fluid modules 100. Inlet channels 222, 224 formed within the inlay can help deliver ambient air toward the inlet of each fluid module. Such a stream of inlet air can supplement or replace air drawn from any open area beneath the inlay (e.g., through any openings or fluid passages formed within the inlay and/or the foundation below and in the vicinity of the fluid modules 100).
With continued reference to FIGS. 16A and 16B, to the extent that the fluid modules produce a waste stream (e.g., fluid passing through the waste side of a thermoelectric device or other temperature conditioning device having main and waste fluid streams), waste channels 212, 214 formed within the inlay can be used to transfer such waste air to the outside of the inlay and the bed assembly. In the illustrated embodiment, the inlet channels extend to the foot-end of the bed or other seating assembly, while the waste channels extend to the head-end of the assembly. In other arrangements, however, the orientation of the channels can be reversed (e.g., so the waste air is transferred to the foot end of the bed when the fluid modules are in use).
In other embodiments, the channels can begin and/or terminate along the sides of the inlay, either in lieu of or in addition to the head-end or foot-end, as desired or required. In yet other arrangements, one or more channels of an inlay can meet, combine or otherwise be placed in fluid communication with one another. By way of example, the inlay embodiment illustrated in FIG. 17 comprises inlet channels 322, 324 that branch off and terminate along two different portions of the inlay edge. For instance, inlet channel 322 extends to both the foot-end and a side of the inlay or interlay component 360, 360′. In addition, the waste channels 312, 314 depicted in FIG. 17 are generally combined (e.g., hydraulically) and extend to three different locations along the head end of the inlay.
Regardless of the exact design and configuration of the intermediate layer, interlay or inlay (or a component thereof), the outlets (e.g., discharge ends of the fluid modules, conduits in fluid communication with the discharge ends of the fluid modules, etc.) that extend to, near or above the top of the interlay (e.g., the upper interlay surface) are advantageously adapted to generally align with corresponding passages of the adjacent mattress or upper portion of the bed assembly. According to some embodiments, as illustrated in FIG. 18 for example, a tube or other conduit 194 can be positioned within each fluid outlet or opening 190 along the top surface 188 of the inlay. In some arrangements, such conduits 194 are shaped, sized and otherwise configured to remain firmly in place within each outlet or opening 190 and to extend upwardly, at least slightly, relative to the top surface of the inlay. The mattress or upper portion of the bed assembly can be positioned over the inlay so that the conduits are inserted within corresponding internal passages of the mattress. This can help ensure that the inlay or interlay components are properly aligned with the mattress or upper portion of the bed or other seating assembly. Further, such a configuration can help prevent relative movement of the inlay and the mattress during use, either in lieu of or in addition to using anti-skid surfaces, layers, components or features between such components.
As illustrated schematically in FIGS. 19A and 19B, once the interlay or inlay 160, 160′ has been aligned relative to the adjacent mattress or upper portion 20, 120, fluid can be delivered from one or more of the fluid modules 100 positioned within the inlay through corresponding internal passages P of the mattress. Air or other fluid is transferred through the passages P to one or more fluid distribution members or layers F (e.g., spacer fabric, open cell foam, other air permeable structures, layers or members, etc.) located along or near the top of the mattress or upper portion 20, 120 of the bed assembly 10, 110, 110′. As shown, one or more air permeable layers T can be located above the fluid distribution members or layers F, as desired or required. Another embodiment of a mattress or upper portion 20, 120 of a bed assembly 10, 110, 110′ is schematically illustrated in FIG. 20. As shown, the mattress 20, 120 can include two or more conditioning zones (e.g., using hydraulically distinct portions 574 within the fluid distribution members or layers F). The various embodiments disclosed herein, including the variations of the intermediate layers (e.g., inlays, interlays or components thereof), foundations and/or the like can be incorporated into any type of climate controlled bed or other seating assembly, such as, for example, foam beds (e.g., full foam beds), spring beds, air chamber beds, futons or other material-filled beds, waterbeds, latex beds, air toppers and the like).
