Abstract
The present disclosure generally pertains to apparatuses and methods for cooling and/or heating feet. In accordance with one exemplary embodiment of the present disclosure, a medium transfer apparatus is inserted into and/or coupled to a shoe. The apparatus has an inlet that can be detachably coupled to a medium injection apparatus, such as a conventional spray can, that injects compressed air or some other cooling medium through the medium transfer apparatus into an interior region of the shoe. Thus, by injecting the cooling medium into the shoe, a user is able to cool his foot without removing his foot from the shoe. In one embodiment, the cooling medium is directed to an insole of the shoe such that the insole is significantly cooled by the cooling medium being injected into the shoe. The cooled insole continues to draw heat from the user's foot and the user continues to feel a cooling sensation long after the cooling medium injection has ended.
Description
- This Application claims priority to U.S. Provisional Application No. 60/831,534, entitled “Apparatuses and Methods for Cooling Feet within a Shoe,” and filed on Jul. 18, 2006, which is incorporated herein by reference.
- A shoe typically provides a finite amount of insulation that traps at least some body heat within the shoe, and a foot placed within a shoe may become heated by trapped body heat or by heat emanating from other sources. Depending on various factors, such as atmospheric temperatures, such heating may cause some discomfort to a user. Moreover, at times, a user may desire to cool one or more of his feet by removing one or more shoes at least temporarily.
- However, cooling one's feet by temporarily removing a shoe can be burdensome or problematic. For example, an athlete competing in an athletic event, such as a football, basketball, or tennis event, may not have sufficient time during a break to remove and then re-don his shoe before play resumes. Indeed, an athlete's shoe is sometimes taped to his foot making it particularly difficult and time consuming to remove a shoe. In addition, non-athletes may also find it burdensome or impractical in at least some circumstances to cool one's feet by temporarily removing shoes for a brief time period.
- Some shoes provide for ventilation to allow air within the shoe to be replaced by air external to the shoe. Although ventilation can assist in reducing temperatures within the shoe under certain circumstances, such temperatures may nevertheless remain at undesirably high levels. Further, in some instances, ventilation can actually exacerbate the aforedescribed heating problems. In this regard, temperatures close to some floor or ground surfaces, such as tennis courts or other athletic playing surfaces, can reach extremely high levels, such as 120 degrees Fahrenheit (F) or more. In such an environment, the temperature of the air entering the shoe can be greater than that of the air exiting the shoe such that ventilation actually results in warming rather than cooling.
- Better techniques for enabling users to cool their bodies and, in particular, their feet are generally desirable.
- The disclosure can be better understood with reference to the following drawings. The elements of the drawings are not necessarily to scale relative to each other, emphasis instead being placed upon clearly illustrating the principles of the disclosure. Furthermore, like reference numerals designate corresponding parts throughout the several views.

FIGS. 1 and 2 depict amedium transfer apparatus 50 in accordance with an exemplary embodiment of the present disclosure. Themedium transfer apparatus 50 comprises anupper layer 52 that has been melded with alower layer 53 to form abead 55 joining the upper andlower layers shaped base 68 and aninlet 69. The upper andlower layers bead 55, form acavity 63 that is airtight except for a plurality ofapertures 66 in theupper layer 52 and except for theinlet 69. As will be described in more detail hereafter, theinlet 69 allows a medium, such as cooled or heated air, to enter thecavity 63, and theapertures 66 allow the medium to exit thecavity 63. - In the embodiment depicted by
FIG. 1 , theinlet 69 is hollow and open at bothends end 72 and pass into thecavity 63 throughend 73. Theend 72 of theinlet 69 forms atab 76 that is wider than athroat 77 of theinlet 69, as shown byFIG. 1 . In one embodiment, the width (w1) of thetab 76 is about 1¼ inches, and the width (w2) of thethroat 77 is about one-quarter of an inch, although w2 increases slightly atend 73 making thisend 73 tapered. By being wider than thethroat 77, thetab 76 is easier to locate and grasp by a user. In addition, a length (l1) of theinlet 69 is about 5⅛ inches, and a length (l2) of thetab 76 is about 1½ inches. In other embodiments, other shapes and dimensions of theinlet 69 are possible. - As shown by
FIG. 1 , thetab 76 has aslit 79 in itsupper layer 52. Theslit 79 provides an opening through which a medium can be injected, as will be described hereafter in more detail. - A width (w3) of the
base 68 is about 10 inches, and a length (l3) of thebase 68 is about 2½ inches. InFIG. 1 , the perimeter of thebase 68 is generally shaped like a foot in two dimensions (2D). However, other shapes and dimensions of thebase 68 are possible in other embodiments. - The
bead 55 forms the outer perimeter of both thebase 68 andinlet 69. Further, eachlayer apparatus 50 is flexible. However, in other embodiments, other types of material, including flexible and/or inflexible material, as well as porous and/or non-porous, may be used, and other dimensions are possible. - In one embodiment, the
apparatus 50 is inserted into a shoe, and theinlet 69 is positioned such thatend 72 is exposed and conveniently accessible to a user.FIG. 3 depicts anexemplary shoe 81 of the prior art. Theshoe 81 comprises anoutsole 84, aninsole 85, and avamp 86. Theoutsole 84 is attached to thevamp 86, and theinsole 85 resides between thevamp 86 and theoutsole 84. When a user is wearing theshoe 81, the bottom of the user's foot is pressed against theupper surface 88 of theinsole 85 such that the user's weight is supported by theoutsole 84 and insole 85 with thevamp 86 covering the top of the user's foot. Although theinsole 85 is inserted between thevamp 86 and theoutsole 84, theinsole 85 is often not fixedly attached to either thevamp 86 or theoutsole 84 so that theinsole 85 can be removed through anopening 89 in thevamp 86. - In one exemplary embodiment, the
base 68 of themedium transfer apparatus 50 is positioned between theoutsole 84 and theinsole 85, as depicted byFIG. 4 . For example, theinsole 85 may be removed from theshoe 81 through theopening 89, and themedium transfer apparatus 50 may be inserted into theshoe 81 through thissame opening 89. In particular, theapparatus 50 may be positioned on the upper surface of theoutsole 84, and theinsole 85 may then be re-inserted into theshoe 81 through theopening 89 such that a bottom surface of theinsole 85 contacts theupper layer 52 of theapparatus 50. Thus, a medium passing through theapertures 66 in thelayer 52 strikes the bottom surface of theinsole 85, as will be described in more detail hereafter. -
FIG. 5 depicts a cross-sectional view of theshoe 81 after theapparatus 50 has been inserted as described above. In the embodiment depicted byFIG. 5 , theinlet 69 has been positioned such that it passes throughopening 89, and theend 72 of theinlet 69 is exposed. In other embodiments, theinlet 69 may be positioned differently. When a person's foot is inserted into theshoe 81, as shown byFIG. 6 , the person's foot, ankle, and/or leg presses theinlet 69 against an inner surface of thevamp 86 thereby keeping theinlet 69 in the same approximate position such that theend 72 remains exposed and accessible. - When desired, a user may cool his foot by interfacing a
medium injection apparatus 110 with the exposedend 72 ofinlet 69 and then using theapparatus 110 to inject a cooling medium, such as compressed air or oxygen, into thecavity 63 of themedium transfer apparatus 50. The cooling medium is forced through theapertures 66 in theupper layer 52 of theapparatus 50 and strikes theinsole 85 lowering the temperature of theinsole 85. Lowering the temperature of theinsole 85 helps to draw heat from the user's foot thereby cooling the user's foot. Further, some of the cooling medium may be forced around the edges of theinsole 85 into the region between thevamp 86 and theinsole 85. Such medium may strike the user's foot further cooling the user's foot. Moreover, injecting the cooling medium into theshoe 81 may provide the user with an immediate cooling sensation as well as significantly lower the temperature of theinsole 85 for a relatively long period of time (e.g., several minutes) so that the user continues to feel a cooling sensation long after the injection. - The material of the
apparatus 50 is flexible in at least one embodiment. In such an embodiment, there may be no space between the upper andlower layers apparatus 50. When medium is injected into theapparatus 50, the medium will slightly separate portions of theupper layer 52 from thelower layer 53 as the medium travels through theapparatus 50. - In one exemplary embodiment, as shown by
FIG. 6 , themedium injection apparatus 110 comprises a spray can 121 having anozzle 125. The cooling medium is contained within the spray can 121 and is under a pressure that is greater than atmospheric pressure. For example, in one embodiment, the cooling medium is under a pressure of about 160-180 pounds per square inch (psi) when measured at an ambient temperature of 130 degrees F. Many conventional spray cans of compressed air or other media are manufactured with contents at about 100 to 200 psi when measured at an ambient temperature of 130 degrees F., and any known or future-developed spray can be used to implement themedium injection apparatus 110. Such spray cans often include a refrigerant. In one embodiment, the cooling medium contained within theapparatus 110 is composed, at least partially, of difluoroxthane. For example, the medium in theapparatus 110 my be a compressed mixture of air and difluoroxthane. Further, other types of devices and other pressures are also possible. - In the embodiment depicted by
FIG. 6 , theapparatus 110 comprises a removablehollow straw 131 that detachably couples thenozzle 125 to theend 72 of theinlet 69. The tip of thestraw 131 and theinlet 69 are dimensioned such that theinlet 69 fits around an outer periphery of the straw tip, as shown byFIGS. 6 and 7 . Various other techniques for interfacing theapparatus 110 and theinlet 69 are possible in other embodiments. Indeed, the use of astraw 131 is unnecessary, and theinlet 69 may be detachably coupled to thenozzle 125 in some other manner. For example, thenozzle 125 may be interfaced directly with theinlet 69. - In the instant embodiment, the cooling medium exiting the
can 121 passes through ahollow tip 126 of thenozzle 125. The inner wall of thetip 126 fits snugly around thestraw 131 such that frictional forces help to keep thestraw 131 coupled to thetip 126 and such that medium exiting through thenozzle 125 preferably does not escape between thestraw 131 andtip 126. In another example, the inner wall of thestraw 131 may be dimensioned to snugly fit around thetip 126. - In addition, the width of the
throat 77 is slightly larger than that of thestraw 131 such that thestraw 131 can be inserted into theinlet 69 through theslit 79 and pass into thethroat 77, as shown byFIGS. 6 and 7 . When a medium is being injected by theapparatus 110, a significant portion of the medium is forced through thethroat 77 into thecavity 63 and then through theapertures 66, as will be described in more detail hereafter. In general, the closer that thestraw 131 is inserted to thetapered end 73, the less likely it is that portions of the injected medium will escape through theslit 79. - In the embodiment shown by
FIG. 6 , thenozzle 125 comprises atrigger 138 that, when actuated by a user, releases the cooling medium within thecan 121 through thenozzle 125. In this regard, actuation of thetrigger 138 transitions thenozzle 125 to a state in which a path is provided from the interior of thecan 121 through thenozzle 125 to the atmosphere or, in the case when thenozzle 125 is interfaced with theinlet 69, to thecavity 63 of theapparatus 50. Since the contents of thecan 121 are under pressure greater than the external pressure, the cooling medium of thecan 121 is expelled through such a path when thetrigger 138 is actuated. When thetrigger 138 is released or otherwise no longer actuated, the path is closed such that the contents of thecan 121 are not allowed to escape. The operation of the spray can 121 described herein may be similar or identical to that of other conventional spray cans and other types of medium injection apparatuses. - In one exemplary embodiment, the cooling medium that is within the
apparatus 110 and injected into theshoe 81 by theapparatus 110 is compressed air. The temperature of the cooling medium compressed at about 160-180 psi can be very low, such as close to or below freezing (i.e., 32 degrees F.) upon exiting thespray can 121. Thus, the cooling medium being injected into theshoe 81 in the instant example is likely significantly colder than the interior region of theshoe 81 prior to the injection. Accordingly, injection of the cooling medium within theshoe 81, as described herein, has a significant effect to the temperatures within theshoe 81 and provides the user with a significant cooling sensation. - In fact, injecting the cooling medium into the
shoe 81, as described above, for only a short time, such as a few seconds, can have a significant and prolonged impact to the temperatures within theshoe 81. In particular, theinsole 85, which is struck directly by the cooling medium in the instant example, can be significantly cooled such that its temperature remains significantly below its original temperature (i.e., its temperate prior to the cooling medium injection) for a prolonged period (e.g., about ten minutes or more) without another injection. Accordingly, an athlete, such as a tennis or football player, may make an injection during a short break in play, yet the effects of the injection may linger well after play has resumed. -
FIG. 8 depicts another embodiment in which themedium transfer apparatus 50 is positioned on theupper surface 88 of theinsole 85 rather than between theinsole 85 and theoutsole 84. In this regard, theupper layer 52 faces theinsole surface 88 such that the cooling medium passing through theapertures 66 strikes and cools theinsole surface 88. However, the presence of theapparatus 50 between the user's foot and theinsole 85 may somewhat shield theinsole 85 from the foot. Depending on the heat transfer characteristics of theinsole 85 and theapparatus 50, theinsole 85 may be better cooled and/or cooled for a longer time period relative to theapparatus 50 such that it would be more preferable for the user's foot to abut theinsole 85, as described above for the embodiment depicted inFIG. 5 . However, the injected cooling medium cools theapparatus 50 as well as theinsole 85, and if desired, theapparatus 50 may abut the user's foot so that heat is drawn from the user's foot by theapparatus 50. - In another exemplary embodiment, the
medium transfer apparatus 50 is positioned on theupper surface 88 of theinsole 85, similar to the embodiment depicted byFIG. 8 . However, thelower layer 53 faces theinsole 85 such that theupper layer 52 faces the user's foot. Thus, the cooling medium passing through theapertures 66 directly strikes the user's foot. In such an embodiment, it is not likely that theinsole 85 is as affected by the injection as in the embodiments described above, possibly limiting the duration of the injection's effect to theinsole 85. In addition, as described above, the temperature of the cooling medium can be very cold, such as close to or below freezing. In such an example, longer bursts of the cooling medium may not be possible without harming the user's foot. Thus, shorter bursts may be desired in order to prevent injury. Such shorter bursts, although giving the user an immediate cooling sensation, may have shorter lasting effects. - As described above, the
medium transfer apparatus 50 may be inserted into theshoe 81 after theshoe 81 has been manufactured, such as by removing theinsole 85, inserting theapparatus 50, and inserting theinsole 85 back into theshoe 81. In other embodiments, theapparatus 50 may be built-in such that it is inserted into theshoe 81 during manufacturing. For example,FIGS. 9 and 10 depict an embodiment in which theapparatus 50 is positioned in theshoe 81 during manufacturing, and theinlet 69 passes through theoutsole 84. In this regard, as best illustrated inFIG. 10 , anend 72 of theinlet 69 protrudes from theoutsole 84. In the depicted embodiment, theend 72 is not wider than thethroat 77. An inner periphery of theend 72 can, however, be about the same as the outer periphery of thestraw 131 such that theend 72 snugly fits around thestraw 131 when thestraw 131 is interfaced with theend 72. In another example, theend 72 may form atab 72 that is wider than thethroat 77, as described above. Except for the positioning of theinlet 69, the configuration of theshoe 81 and theapparatus 50 may be identical to any of the embodiments previously described above. In the embodiment depicted byFIGS. 9 and 10 , theoutsole 84 may be manufactured with a groove (not shown) through which theinlet 69 may be inserted when theapparatus 50 is positioned during manufacturing. In other embodiments, theinlet 69 may pass through other components of a shoe. For example, theinlet 69 may pass through a hole in thevamp 86. - In addition, in several of the embodiments described above, the width of the
straw 131 has been described as being smaller than the width of theinlet 69 and, in particular, thethroat 77 of theinlet 69. However, it is possible for the width of thestraw 131 to be greater than the width of theinlet 69. As an example, theend 72 of theinlet 69 could be composed of a rigid material having an outer periphery slightly smaller than the inner periphery of thestraw 131. In such an embodiment, themedium injection apparatus 110 could be interfaced with themedium transfer apparatus 50 by inserting theend 72 into thestraw 131 such that thestraw 131 fits snugly around theend 72. Various other techniques for interfacing themedium transfer apparatus 50 with themedium injection apparatus 50 would be apparent to one of ordinary skill in the art upon reading this disclosure. - In some embodiments described above, the
medium transfer apparatus 50 is composed of flexible material. However, theapparatus 50 may be composed of inflexible material or a combination of flexible and inflexible material. For example, theinlet 69 may be composed of a rigid material, such as a rigid plastic material, and the base 68 may be composed of a flexible material. In another example, theend 72 may be covered by a hollow and rigid tip (not shown). Such a rigid tip may facilitate interfacing of theapparatuses -
FIGS. 11 and 12 depict ashoe 81 in accordance with an exemplary embodiment of the present disclosure. The embodiment shown byFIGS. 11 and 12 is identical to that shown byFIG. 5 except that theinlet 69 is embedded in thevamp 86 and has arigid tip 99 atend 72. Thestraw 131 may be interfaced with thetip 99 so that the cooling medium can be injected viainlet 69 into thecavity 63 of theapparatus 50 similar to the embodiments previously described above. Thetip 99 is hollow and dimensioned such that thestraw 131 snugly fits around thetip 99 or vice versa. For example, the outer periphery of thetip 99 may be about the same as the inner periphery of thestraw 131 so that thestraw 131 fits snugly around thetip 99, or the outer periphery of thestraw 131 may be about the same as the inner periphery of thetip 99 so that thetip 99 fits snugly around thestraw 131. - Note that the
apparatus 50 may be positioned differently in other yet embodiments. For example, thebase 68 of theapparatus 50 may be embedded within theinsole 85. In such an embodiment, theinsole 85 may have a hole (not shown) for allowing theinlet 69 to pass out of theinsole 85, or theinlet 69 may be an integral component of theinsole 85. If theinlet 69 passes through a hole in theinsole 85, such a hole may be large enough to allow the injected medium to exit theinsole 85, or theinsole 85 may have additional holes for allowing the injected medium to exit. In addition, thelayers insole 85 so that theapparatus 50 can replace theconventional insole 85 or be used in lieu of theconventional insole 85. - It should be emphasized that in any of the embodiments described above, the
nozzle 125 may be interfaced directly with themedium transfer apparatus 50 without the use of astraw 131. For example, in the embodiment depicted byFIGS. 11 and 12 , theshoe tip 99 may fit snugly intonozzle tip 126 or vice versa. As an example, the outer periphery of theshoe tip 99 may be about the same as the inner periphery of thenozzle tip 126 so that thenozzle tip 126 fits snugly around theshoe tip 99, or the outer periphery of nozzle thetip 126 may be about the same as the inner periphery of theshoe tip 99 so that theshoe tip 99 fits snugly around thenozzle tip 126. - An exemplary use and operation of a
medium transfer apparatus 50 will be described in detail hereinbelow with particular reference toFIG. 13 . - Assume that a user of the
shoe 81 shown byFIG. 3 desires to use themedium transfer apparatus 50 to cool his feet when wearing theshoe 81. Before donning theshoe 81, the user removes theinsole 85 and inserts themedium transfer apparatus 50 into theshoe 81, as shown byblock 211 ofFIG. 13 . The user then inserts theinsole 85 back into theshoe 81 on top of theapparatus 50, as shown byFIGS. 4 and 5 . In other examples, theapparatus 50 may be inserted and/or attached to theshoe 81 by the shoe manufacturer such that it is unnecessary for the user to insert theapparatus 50 into theshoe 81. - At some point, the user may desire to use the
apparatus 50 for cooling his foot. For example, the user may be an athlete, such as a football player, and desire to use theapparatus 50 for cooling his foot after coming to the sideline during a football game. In another example, the user may be a tennis player and desire to use theapparatus 50 to cool his foot during a break between sets. - To cool his foot, the user interfaces the
medium injection apparatus 110 with theinlet 69 so that the cooling medium in theapparatus 110 can be injected into themedium transfer apparatus 50 through theinlet 69, as shown byblock 215 ofFIG. 13 . For illustrative purposes, assume that theapparatus 110 comprises aspray can 121, as described above with reference toFIG. 6 , and that the cooling medium is composed of compressed air and a refrigerant, although other types ofmedium injection apparatuses 110 and cooling media may be used in other examples. In the instant example, the user couples one end of thehollow straw 131 to thenozzle 125 such that any of the cooling medium exiting theapparatus 110 passes through thestraw 131. The user also inserts the opposite end of thestraw 131 into theinlet 69 through theslit 79 such that the cooling medium passing through thestraw 131 enters theinlet 69 and passes into thecavity 63 of theapparatus 50. - The user then operates the
medium injection apparatus 110 such that cooling medium within theapparatus 110 is injected into themedium transfer apparatus 50, as shown byblock 221 ofFIG. 13 . In the instant example, the user actuates thetrigger 138 such that the cooling medium, which is under pressure, is forced out of theapparatus 110 through thenozzle 125. During injection, the relatively high pressure within theapparatus 110 forces the cooling medium through thestraw 131 andinlet 69 into thecavity 63. In addition, such pressure also forces the cooling medium out of thecavity 63 through theapertures 66 such that the cooling medium strikes theinsole 85 thereby cooling theinsole 85. In the instant example, the cooling medium is pressurized to about 160-180 psi when measured at an ambient temperature of 130 degrees F., although other pressures are possible in other examples. - The duration of the injection may be for any time period, and the user may make more than one injection, if desired. Generally, the longer that cooling medium is injected into the
shoe 81 viaapparatus 50, the greater is the cooling effect to the user's foot and to theinsole 85. In one example, the user maintains an injection for about 5 to 10 seconds. Such a duration, at the exemplary pressures described above for the instant example, can provide a significant cooling effect. Indeed, theinsole 85 may remain below its original temperature (i.e., its temperature prior to the injection) for several minutes after the injection has ended. Moreover, theinsole 85 may continue cooling the user's foot long after the injection has ended. Eventually, heat from the user's foot and/or other sources may raise the temperature of theinsole 85 back to its original temperature, but at any time, the user may perform another injection to again cool his foot and theinsole 85, as described above. - After performing at least one injection, the user decouples the
medium injection apparatus 110 from themedium transfer apparatus 50, as shown byblock 225, so that themedium injection apparatus 110 does not interfere with the user's activities. In the instant example, the user can decouple themedium injection apparatus 110 from themedium transfer apparatus 50 by simply pulling thestraw 131 out of theinlet 69. - There are various methods that can be used to manufacture the
medium injection apparatus 50. One exemplary method will be described in more detail hereinbelow with particular reference toFIG. 14 . - Initially, two sheets of material for forming the
layers block 311 ofFIG. 14 . In one example, each of the sheets is composed of PVC and is about 0.006 inches thick, although other types of material and other thicknesses are possible in other examples. One of the sheets is punctured to formapertures 66, as shown byblock 314 ofFIG. 14 . Any known or future-developed process of puncturing a sheet of material may be used. - One of the sheets is then overlaid with the other sheet, such that one of the sheets-is positioned on top of the other sheet, as shown by
block 316 ofFIG. 14 . The two sheets are then melded to form thebead 55, as shown byblock 317 ofFIG. 14 . In one embodiment, a thermoformer is used to meld the two sheets inblock 317. A thermoformer is a well-known press that uses radio frequency (RF) sealing for forming a seal. Such a seal can be of just about any desired pattern. In the instant example, a pattern is selected such that the perimeter of the bead portion forming thebase 68 is in the general shape of a foot outline, as shown byFIG. 1 , although other types of shapes are possible in other examples. - Once the
bead 55 has been formed, thebead 55 and the sheet material within the perimeter of thebead 55 are separated from the remainder of the sheet material to provide theapparatus 50 depicted inFIG. 1 , as shown byblock 325 ofFIG. 14 . In this regard, the portion of the sheet material forming theapparatus 50 can be easily separated from the remainder of the sheet material by hand, although some type of automated separating process may be used instead. - The above embodiments have been described as injecting a medium for cooling a user's foot. In other examples, the injection
medium apparatus 110 may contain a heated medium, which can be injected into theshoe 81 according to the same or similar techniques described above for injecting a cooling medium so that the user's foot and/or theinsole 85 can be warmed instead of cooled. - Additionally, it should be emphasized that the aforedescribed embodiments of the
medium transfer apparatus 50 and themedium injection apparatus 110 are exemplary, and other configurations of theapparatuses shoe 81 depicted above is also exemplary, andapparatuses medium transfer apparatus 50 is described above for illustrative purposes, and other methods of manufacturing amedium transfer apparatus 50 are possible.
