Definitions
- Thermal performance data disclosed herein was obtained using a temperature controlled test chamber held at 4°C in which prior art inflatable bodies and a plurality of inflatable bodies constructed according to the invention embodiments were subjected to an insulated heat source (a three zone guarded heat plate operatively linked to a computer) on one side and heat sink (a large aluminum plate with a plurality of temperature probes also linked to a computer) exposed to the controlled environment on the other side.
- the thermal performance of a subject mattress was then established by determining the amount of electrical power needed to maintain the heat source at a constant temperature of 33.3°C while also maintaining the temperature of the heat sink at the ambient temperature. Once stabilized, the amount of electrical power needed to maintain this steady state correlated with the heat energy passing from the heat source, through the subject mattress and into the heat sink, and ultimately rejected into the environment. In this manner, the electrical equivalent of the thermal transmission rate could be determined.
- a preferred embodiment of the invention comprises a foam planar sheet to which is selectively bonded at least one non-woven or batting-type material as a serpentine or corrugating sheet, and at least one envelope panel having a radiant heat transfer mitigation treatment thereon, preferably on an interior surface thereof.”
- the incorporation of metals and/or metalized materials into such bodies may also decrease the overall thermal performance of the inflatable body due to conduction by the metalized films and/or treated materials, and necessarily increases the weight of the inflatable body. As a consequence, the adage of "if one is good, then more must be better" does not necessarily hold true.
- the present invention is directed towards inflatable bodies having improved means for mitigating thermal radiation transmission from one side of the inflatable body to an opposing side.
- the improved means which broadly comprise the incorporation of at least one selectively linked and spaced apart intra-body radiant barrier, yield unexpected gains in thermal performance for inflatable bodies that otherwise might not find utility in certain environmental conditions, as will be described below.
- inflatable body refers to any collapsible-inflatable fluid retaining structure, whether self-inflating or not, comprising first and second sides (whether formed from discrete sheets or panels, or a single sheet or panel of material) that at least partially define a substantially fluid
- impermeable envelope and that are selectively linked to each other by intra-envelope tensile means (whether directly by discrete members, or indirectly by a plurality of members or a system of members), i.e., the linkage occurs within the envelope.
- This selective linkage of opposing sides differs from inflatable bodies having substantially coextensive linkage arrangements, such as found in prior art self-inflatable bodies that rely upon open cell foam cores that are substantially bonded to both sides, like Cascade Designs' THERM-A-REST mattresses: when inflatable body embodiments according to the invention are inflated, thereby causing the opposing sides to separate or displace from each other, the degree of separation or displacement is not uniform over the opposing sides; the non-selectively linked portions of each side are permitted to distend from virtual plane comprising the selective linkage locations.
- first and second sides of inflatable body embodiments of the invention may be characterized as panels, each having an inner surface presenting to the envelope and an outer surface presenting to the environment.
- collapsible cellular matrix cores found in several invention embodiments comprise a plurality of generally geometrically identical cells (hollow, open-ended geometric prisms, each defining a major axis) that are formed or linked together to establish a repeating geometric pattern (a "row"), wherein the major axes of the prisms are generally perpendicular to a perimeter portion of the inflatable body and selective portions of the matrix ("linking locations") are directly or indirectly bonded to inner surfaces of opposing panels, whereby the matrix functions as the tensile means for the inflatable body.
- a repeating geometric pattern a repeating geometric pattern
- a plurality of substantially triangular hollow, open-ended prisms comprises the cellular matrix, wherein at least each of some prisms, but not all prisms, are defined by two portions of a corrugating film or thin sheet material such as a spun or non-woven filament batting and one portion of a generally planar film or thin sheet material such as a spun or non-woven filament batting.
- outer rows of the matrix generally comprise triangular prisms alternating with open spaces that resemble "V" shaped channels. In other words, visually, the result is WWWWW for an arbitrary outer row.
- the opposing panels that form the envelope for the inflatable body would cap or close the "V" shaped channels, thereby constituting a third wall for
- an inflatable body comprising a cellular matrix of the type referenced herein is augmented with at least one means for mitigating thermal radiation transmission, as herein described.
- the radiant barrier means of the various embodiments forming the several groups within this series comprise at least one film-based, radiant barrier established intermediate the matrix and an otherwise adjacent inflatable body panel. Each such intermediate radiant barrier preferably has greater radiant energy reflectivity than any other conventional component of the inflatable body, i.e., non-specialized or non-metalized component.
- the intermediate radiant barrier (or in the case of plural intermediate radiant barriers, the inner most barrier) functions to establish the third wall of at least some triangular hollow, open-ended prisms as opposed to the adjacent or proximate panel, as the case may be, in conventional cellular matrix based inflatable bodies.
- intermediate radiant barrier maybe the as the distance between corresponding linking locations on the otherwise adjacent panel if a space or void between the panel and the intermediate radiant barrier can result after inflation of the inflatable body. Such a result may occur depending upon distortion of the cellular matrix upon inflation and/or differences between the mechanical properties of the matrix and the panel, as well as gravitational orientation.
- a first group of invention embodiments within this series comprise a single intermediate radiant barrier established between the cellular matrix and an adjacent body panel wherein the distance in at least one direction between adjacent linking locations on the intermediate radiant barrier is less than the distance between corresponding linking locations on the panel.
- An alternative to the foregoing embodiment has the distance in at least one direction between adjacent linking locations on the intermediate radiant barrier greater than the distance between corresponding linking locations on the panel.
- each additional intermediate radiant barrier is established inwardly (toward the cellular matrix) of a previous intermediate radiant barrier wherein the distance between adjacent linking locations in same direction as considered in the previous
- intermediate radiant barrier is less than (or in the alternative greater than) the distance between corresponding linking locations on the previous intermediate radiant barrier.
- a cellular matrix of the type referenced herein for use with an inflatable body is augmented with at least one means for mitigating thermal radiation transmission, as herein described.
- the radiant barrier means of the various embodiments within this series comprise at least one film-based, radiant barrier established intermediate two rows of triangular hollow, open-ended prisms that form part of the cellular matrix.
- the first group of this second series seeks to establish an additional element to the inflatable body as opposed to replacing and/or enhancing an existing element.
- the present thermal radiation mitigation means which is preferably a film-based radiant barrier, is established between an existing generally planar film or thin sheet material such as a spun or non-woven filament batting, itself intermediate the two rows of prism, and an otherwise adjacent row of prisms. Also as with the first group of the first series, this radiant barrier functions to establish the third wall of at least some triangular hollow, open-ended prisms, but instead with respect to the existing substantially planar film or sheet. As a consequence, no prism in one row shares a common enclosing wall with any prism in an adjacent row.
- intermediate radiant barrier is preferably less than, but can also be greater than, the distance between corresponding linking locations on the existing substantially planar film or sheet. If the existing substantially planar film or sheet is best characterized as a non-film, then equivalent distances are considered within the scope of the invention due to the different mechanical properties between the two materials.
- an inflatable body according to this series has a cellular matrix with radiant barrier means for mitigating thermal radiation transmission intermediate the cellular matrix and both opposing panels as well as intermediate two rows of triangular hollow, open-ended prisms.
- Test have shown that inflatable bodies having a thickness of about 2.5" (-6.25 cm) and comprising these modifications have thermal insulation values of about R-4.9.
- a conventional inflatable mattress having a 2" (-5.0 cm) thick piece of 0.9 density open cell polyurethane foam has a comparable "Ft" value, but weights almost five times more and, when manually compressed for storage, displaces about four times the volume. If the existing generally planar film or thin sheet material can be characterized as having thermal radiation transmission mitigation properties the same as or similar to that of the intermediate radiant barrier, then the thermal insulation value increases to about Ft-5.7.
- the inflatable bodies described and shown herein are not limited to camping mattresses, but may find utility in any application that can utilize many of its key properties: thermal management, compact storage, ease of deployment (inflatable), light weight and structural stability. Potential uses such as portable structures or tents, seating ,window shades, thermally insulated boxes or containers, water cooling and heating systems, cold-weather clothing, sleeping bags and systems, and shock or impact attenuation systems.
- Fig. 1 is a perspective view a prior art inflatable body having tensile means in the form of a cellular matrix, wherein opposing panels form a plurality of the triangular, hollow open-ended prisms that comprise the matrix;
- Fig. 2 is a perspective view a first series embodiment of an inflatable body according to the invention wherein an intermediate radiant barrier is established between the cellular matrix and one panel;
- Fig. 3 is a perspective view a derivative of the embodiment of Fig. 2, wherein a second intermediate radiant barrier is established between the cellular matrix and an opposing panel;
- Fig. 4 is a perspective view a derivative of the embodiment of Fig. 3, which incorporates aspects of a second series embodiment according to the invention, wherein a third intermediate radiant barrier is established between rows of prisms within the cellular matrix.
- FIG. 1 prior art inflatable mattress 10 is shown having outer panels 20a and 20b, planar or bifurcating member 30 and corrugating or serpentine members 40a and 40b. Together, these components form prisms 50, which in the aggregate, create rows I and II.
- Each prism 50 further includes three linking locations, alternately two for linking with a panel 20a or 20b and one for linking with member 30, or one for linking with a panel 20a or 20b and two for linking with member 30. These linking locations correspond to complementary linking locations on the noted panels and member.
- FIG. 2 shows a modified version of mattress 10 according to one aspect of the invention.
- Modified mattress 100 includes intermediate radiant barrier 60b, which is established between row II and panel 20b. As illustrated, the distance between linking locations of panel 20b is greater than the distance between linking locations of radiant barrier 60b, thereby forming spaces or voids 70b.
- FIG. 3 further modifies mattress 100 according to another aspect of the invention.
- Modified mattress 200 includes intermediate radiant barrier 60a, which is established between row I and panel 20a. As illustrated, the distance between linking locations of panel 20a is greater than the distance between linking locations of radiant barrier 60a, thereby forming spaces or voids 70a.
- Fig. 4 further modifies mattress 200 according to another aspect of the invention.
- Modified mattress 300 includes intermediate radiant barrier 60c, which is established between planar or bifurcating member 30 and corrugating or serpentine members 40a of row I. As illustrated, the distance between linking locations of planar or bifurcating member 30 is less than the distance between linking locations of radiant barrier 60c, thereby forming spaces or voids 70c.
