The system is characterized in that gaseous material is drawn from the inlet line and pumped via the outlet line into the inner volume of the article of footwear, which has a cooling effect as well as pumping away noxious odors and eliminating a bacteria-friendly environment.
Description
- The present invention is in the field of footwear primarily for humans, and pertains more specifically to apparatus and methods for ventilating footwear in use.
- It is very well-known that there are many problems associated with footwear for people. Among these problems are many associated with perspiration and with the close enclosure typically provided by most kinds of shoes and other footwear. For example, in prolonged use the environment surrounding a user's foot in most footwear may become elevated in temperature and moist from perspiration, which provides a suitable breeding environment for bacteria, and often leads to unpleasant odors, discomfort, and in some cases to uncomfortable blisters and/or rashes. These problems are typically more pronounced with such as athletic footwear.
- What is clearly needed in the art is apparatus and methods for ventilating footwear in use by causing air or other gases to be circulated between a user's foot and the surrounding footwear.
- In a preferred embodiment of the present invention a ventilation system for a shoe is provided, comprising a gas-motive device, an inlet line to the gas-motive device, and an outlet line to the gas motive device, the outlet line communicating to an inner volume of the shoe. The system is characterized in that gaseous material is drawn from the inlet line and pumped via the outlet line into the inner volume of the shoe.
- In some preferred embodiments the gas-motive device is a hollow and deformable bladder device with structural integrity to return the bladder after deformation to an un-collapsed condition. Also in some preferred embodiments the inlet line communicates to outside the shoe, and the gaseous material is ambient air. In some embodiments the outlet line communicates through a manifolding system to several points into the interior of the shoe, and in others the outlet line communicates through porous inner panels for distributing air into the inner volume of the shoe.
- In some embodiments there are one or more one-way valves in the inlet or the outlet lines for controlling the direction of pumping action. In some cases as well, the inlet and the outlet lines may be the same line, or both may go the inner volume of the shoe, and gaseous material is alternately drawn from the inner volume of the shoe, and urged into the inner volume of the shoe.
- In some cases the arrangement is to place the bladder under the heel of the shoe, such that walking or running action placing a user's weight on the heel area alternately collapses and un-collapses the bladder. In other cases arrangement is to place the bladder under the forward area of the shoe toward the toe region, such that walking or running action placing a user's weight on the forward area alternately collapses and un-collapses the bladder.
- In an alternative embodiment of the invention there is a reservoir connected to the inlet line to the gas motive device, the reservoir holding one or more of a solid,semi-solid or liquid perfume, deodorant, fungicide, or anti-bacterial agent, such that gaseous material drawn into the gas-motive device for transfer into the inner volume of the shoe is integrated with the contents of the reservoir. This feature allows deodorants, perfumes, antibiotics, and the like to be administered into the inner volume of the shoe around a user's foot while the user is using the shoe, walking or running.
- In another aspect of the invention an article of footwear is provided, comprising a sole region for underlying a user's foot, an upper region for engaging a user's foot in use, to stabilize the footwear on the user's foot, and defining an inner volume around the user's foot, and a ventilation system including a gas-motive device, an inlet line to the gas-motive device, and an outlet line to the gas motive device, the outlet line communicating to an inner volume of the shoe. The footwear is characterized in that gaseous material is drawn from the inlet line and pumped via the outlet line into the inner volume.
- In some preferred embodiments the gas-motive device is a hollow and deformable bladder device with structural integrity to return the bladder after deformation to an un-collapsed condition. Also in some preferred embodiments the inlet line communicates to outside the shoe, and the gaseous material is ambient air. The outlet line may communicate through a manifolding system to several points into the interior of the shoe, or through porous inner panels for distributing air into the inner volume of the shoe.
- In some embodiments there are one or more one-way valves in the inlet or the outlet lines for controlling the direction of pumping action. Also in some embodiments the inlet and the outlet lines are the same line, and gaseous material is alternately drawn from the inner volume of the shoe, and urged into the inner volume of the shoe. In some cases the bladder will be under the heel of the shoe, such that walking or running action placing a user's weight on the heel area alternately collapses and un-collapses the bladder. In other cases the bladder may be under the forward area of the shoe toward the toe region, such that walking or running action placing a user's weight on the forward area alternately collapses and un-collapses the bladder.
- In an alternative embodiment there is a reservoir connected to the inlet line to the gas motive device, the reservoir holding one or more of a solid, semi-solid or liquid perfume, deodorant, fungicide, or anti-bacterial agent, such that gaseous material drawn into the gas-motive device for transfer into the inner volume of the shoe is integrated with the contents of the reservoir.
- In yet another aspect of the invention a method for ventilating a shoe is provided, comprising the steps of (a) incorporating a gas-motive device having an inlet line and an outlet line into the shoe, the outlet line communicating to an inner volume of the shoe; and (b) operating the gas motive device to move gaseous material drawn from the inlet line into the inner volume of the shoe.
- In some preferred embodiments the gas-motive device is a hollow and deformable bladder device with structural integrity to return the bladder after deformation to an un-collapsed condition, such that shifting a user's weight onto an off an area over the bladder operates the bladder as a bellows pump. Also in some preferred embodiments of the method the inlet line communicates to outside the shoe, and the gaseous material is ambient air. In some embodiments as well, the outlet line communicates through a manifolding system to several points into the interior of the shoe, or in some embodiments through porous inner panels for distributing air into the inner volume of the shoe. There may be one or more one-way valves in the inlet or the outlet lines for controlling the direction of pumping action.
- In some embodiments the inlet and the outlet lines may be the same line, and gaseous material is then alternately drawn from the inner volume of the shoe, and urged into the inner volume of the shoe. In some cases the bladder will be under the heel of the shoe, such that walking or running action placing a user's weight on the heel area alternately collapses and un-collapses the bladder, and in other cases the bladder will be under the forward area of the shoe toward the toe region, such that walking or running action placing a user's weight on the forward area alternately collapses and un-collapses the bladder.
- In another alternative embodiment there will be a reservoir connected to the inlet line to the gas motive device, the reservoir holding one or more of a solid, semi-solid or liquid perfume, deodorant, fungicide, or anti-bacterial agent, such that gaseous material drawn into the gas-motive device for transfer into the inner volume of the shoe is integrated with the contents of the reservoir.
- In yet another aspect of the invention a ventilating insert for a shoe is provided, comprising a region shaped substantially as the insole of a shoe, for underlying a user's foot, and a ventilation system including a gas-motive device, an inlet line to the gas-motive device, and an outlet line to the gas motive device, the outlet line communicating through the insole-shaped region. The insert is characterized in that gaseous material is drawn from the inlet line and pumped via the outlet line through the insole-shaped region.
- In preferred embodiments the gas-motive device is a hollow and deformable bladder device with structural integrity to return the bladder after deformation to an un-collapsed condition. Also in preferred embodiments the inlet line communicates to outside the shoe, and the gaseous material is ambient air.
- In some embodiments the inlet line communicates through a breathing tongue connected and positioned to lie behind a user's heel with the insert in a shoe, and also in some embodiments the outlet line communicates through a porous inner panel of the insole-shaped region.
- There may be in the insert one or more one-way valves in the inlet or the outlet lines for controlling the direction of pumping action. Further the inlet and the outlet lines may be the same line, and gaseous material is alternately drawn from the inner volume of the shoe, and urged into the inner volume of the shoe.
- In some cases the insert is arranged to place the bladder under a user's heel, such that walking or running action placing a user's weight on the heel area alternately collapses and un-collapses the bladder, while in other cases the arrangement is to place the bladder under the forward area of a user's foot, such that walking or running action placing a user's weight on the forward area alternately collapses and un-collapses the bladder. Further still, there may be a reservoir connected to the inlet line to the gas motive device, the reservoir holding one or more of a solid, semi-solid or liquid perfume, deodorant, fungicide, or anti-bacterial agent, such that gaseous material drawn into the gas-motive device for transfer into the inner volume of the shoe is integrated with the contents of the reservoir.
- In various embodiments of the invention, several of which are described in enabling detail below, for the first time a system is provided that ventilates a shoe, a piece of footwear, solving a long-standing problem.

apparatus 103 in more detail. - FIG. 4 is a bottom view of a shoe similar to the shoe of FIG. 3, in an alternative embodiment of the invention.
- FIG. 5 is a bottom view of a shoe similar to the shoes of previous figures, but with yet a different arrangement of elements.
- FIG. 6 is a side elevation view of a shoe similar to that illustrated in FIG. 2, to illustrate another element in a preferred embodiment of the invention.
- FIG. 7 is a side elevation view of a shoe having a separate ventilator apparatus placed therein, in an alternative embodiment of the present invention.
- FIG. 8a is a side elevation view of the separate ventilator apparatus of FIG. 7.
- FIG. 8b is a plan view of the separate ventilator apparatus of FIG. 8a, illustrating further detail of the constituent elements.
- FIG. 1 is a side elevation view of a representative
athletic shoe 101 showing innovativeinternal apparatus 103 within a lowersole structure 102 according to an embodiment of the present invention. In a preferred embodiment of theinvention apparatus 103 draws air from outside the shoe and pumps that air into the interior of the shoe around a user's foot. In this preferred embodiment manipulation ofapparatus 103 is by the action of the user in walking or running with the shoe. - FIG. 2 is a side elevation view of the shoe of FIG. 1 with a portion of the sole of the shoe cut away to show the eternal elements of
apparatus 103 outlined in FIG. 1. In this embodiment a pumpingbladder 104 is positioned against astop structure 109 in the heel area ofshoe 101. This bladder is a gas-motive device as is further described below. Anair inlet line 105 communicates through a one-way valve 106 with outside environment through thesole structure 102 in the heel of the shoe. The active direction ofvalve 106 is towardbladder 104, so depression ofbladder 104 will closevalve 106, preventing expulsion of air throughline 105; and expansion ofbladder 104 will cause air to be drawn into the bladder throughline 105 andvalve 106. -
Bladder 104 in this simple case is a hollow, flattened circular structure with enough structural integrity to assume a fully-expanded shape in the absence of force on the heel of the shoe; that is, when a person is not supporting his/her weight on the heel area of the shoe.Bladder 104 in this embodiment also communicates through a one-way valve 107 and aline 108 forward and upward through the insole ofshoe 101 into the interior ofshoe 101. The active direction of one-way valve 107 is toward the interior of the shoe frombladder 101, such that action ofbladder 104 being depressed by a person shifting weight to the heel area of the shoe will force air in the bladder throughvalve 107 into the interior ofshoe 101. - FIG. 3 is a bottom plan view of
shoe 101 of FIG. 2 illustrating the elements ofapparatus 103 in more detail. In thisembodiment bladder 104 feeds through aline 112 through one-way valve 107 into atee 111 which connects bylines 113 to separateelbows 110 and toindividual lines 108 on opposite sides of the shoe. The lines and connections can be plastic-molded lines, elbows and tees, and in some cases pieces of flexible and/or semi-flexible tubing such as Tygon™ plastic tubing. Also, there are many sorts of one-way valves that may be suitable, such as flapper valves and ball valves that are commercially available for one-way fluid applications. There are many possibilities. - In operation with the arrangement and elements of the embodiment of the invention illustrated in FIGS. 1 through 3, when a user takes a walking or a running step, transferring the user's weight onto the heel area of
shoe 101,bladder 104 gets depressed to some extent, depending on the resiliency ofbladder 104, the weight of the user, and the force of the action, and possibly other variables. The depression of the bladder reduces the internal volume of the bladder, one-way valve 106 is urged closed, and air in the bladder is urged through one-way valve 107, through the tubingsystem including lines 108, and into the internal volume of the shoe. - As the same user continues to walk or run, and takes another step, for example, shifting the user's weight to the opposite foot, which may have a similarly-enabled shoe,
bladder 104, by virtue of its structural integrity, assumes its fully-expanded, as-molded shape, which expands the internal volume of the bladder to a greater volume than it has when the user has his/her weight in the heel area of the shoe. The expansion ofbladder 104 closes one-way valve 107 and opens one-way valve 106, and outside air is drawn intobladder 104 throughline 105. - Thusly, walking or running action causes air to incrementally be pumped through the shoe around a user's foot, effectively ventilating the shoe. The pumping action reduces the ambient temperature in the volume of the shoe around the user's foot, moves away any stagnant air, and reduces or eliminates all of the problems described above in the Background section stemming primarily from the conventional lack of ventilation.
- FIG. 4 is a bottom view of a
shoe 114 similar toshoe 101 described above, in an alternative embodiment of the invention. In thisembodiment bladder 104 with inlets and outlets, and one-way valves Shoe 101 previously described. Rather thanindividual tubings 108 as shown forshoe 101,shoe 114 has asingle manifold 115 having a series ofopenings 116 which communicate upward through the inner sole of the shoe into the interior volume of the shoe. The action in use is essentially the same, and the manifold provides a different distribution of air into the interior of the shoe. - In other alternative embodiments of the invention different manifolds and manifold systems may be used to distribute air into the shoe in a variety of different patterns, including by, for example an inflatable insole connected to one or more manifolds from the bladder, which insole may have a porous upper surface below the user's foot, such that air pumped into the shoe may diffuse through the special insole over all or a substantial portion of the bottom of the shoe. Such porous insoles may be extended also as porous linings on the sides of the inside of the shoe, and even some top portions, so outside air my be provided and relatively evenly distributed with a shoe so equipped.
- FIG. 5 is a bottom view of a
shoe 117 similar toshoes embodiment bladder 104 is positioned near the front of the shoe substantially where a user would apply weight from the forward area of the foot just behind the toes. In many applications this position, or a similar position might be preferable to the heel position described above. In this case aninlet line 118 protrudes to the front through one-way valve 106, andlines 119 deliver pumped air to two positions just in front of the heel area. It will be apparent to the skilled artisan that a wide variety of manifolding schemes may be employed from this position of the bladder, just as described above for the heel position of the bladder, including such as porous insoles and the like. - FIG. 6 is a side elevation view of a
shoe 122 similar to that illustrated in FIG. 2, to illustrate another element in a preferred embodiment of the invention. Inshoe 122 the inlet line frombladder 104 extends from the heel area into areservoir 120 having a cap or plug 121, which may be opened to place a solid, semi-solid or liquid perfume, deodorant, fungicide, or anti-bacterial agent, or any combination, intoreservoir 120. Air is then drawn intobladder 104 through or around the agent in the reservoir, and the air thusly pumped into the interior of the shoe is then treated accordingly, providing even further advantages for the user. It will be apparent to the skilled artisan that such a reservoir and such agents may be arranged and enabled in a variety of ways, and is broadly applicable to all of the various arrangements of pumping elements and manifolds previously described. - It will be apparent to the skilled artisan that there are many alterations that may be made to the embodiments described without departing from the spirit and scope of the invention. For example, there are alternative apparatus for pumping air or other gases than the bladder shown as an example. Some may be powered by the user's action, and some may be powered by, for example, electromotive devices for pumping air or other gases. In the latter case, one-way valves may not be necessary. In some case restrictive valves and devices may be used to tune the amount of air pumped. Air may be drawn in from outside the shoe, or drawn from the interior of the shoe to create a re-circulating effect, which may be useful when using the embodiment shown by FIG. 6, or a similar arrangement, to preserve, for example, the material added by the reservoir. In this alternative embodiment one might draw air from one end of the shoe, add a deodorant or other material, and return the deodorized air to the other end of the shoe. In an alternative embodiment a relatively large volume bladder may be used with a single line into the shoe without a: valve, such that air is alternately pumped into and drawn out of the shoe. There are very many possibilities.
- In an alternative embodiment of the present invention, illustrated in FIG. 7, FIG. 8a and FIG. 8b, a shoe ventilation system is provided, incorporated in an insole for a shoe, such that the unique apparatus may be inserted into virtually any existing shoe to provide the functions and advantages described above relative to FIGS. 1-6. It should be understood that the example of an insole as an insert is not limiting, and the features described may also be provided for an arch support, or in other sorts of inserts that may be used. The idea is to provide the features of the invention in an aftermarket device as well as in footwear OEM.
- FIG. 7 is a side elevation view of a
shoe 701 having aseparate ventilator apparatus 702 placed therein, much in the manner that a person would place an insole or an arch support, for example, into a shoe. - FIG. 8a is a side elevation view of
apparatus 702 removed fromshoe 701, and also showing further constituent elements ofapparatus 702. FIG. 8b is a plan view ofapparatus 702 of FIG. 8a, illustrating further detail of the constituent elements.Apparatus 702 has equivalent elements to the system previously described, which is built into the sole region of a shoe. There is, for example, aportion 710 that lies in the bottom of the shoe, just as is common for an insole.Portion 710 is connected to abreathing tongue 703 which will lie substantially vertically in the shoe behind a user's heel. Breathingtongue 703 is a substantially flat element having an internal cavity for conducting air from outside the shoe, through a one-way valve 706 into apump bladder 707 built into or molded into the device.Pump bladder 707 operates by virtue of a user's shifting of weight, just as previously described for other embodiments, and urges air from the bladder into aregion 709 withinportion 710. -
Portion 710 in this embodiment has a matrix of small openings through the upper surface ofregion 710 to allow air to be urged into the volume inside a shoe surrounding a user's foot. As a person walks or runs, air is pumped from outside the shoe into the inner volume of the shoe, providing beneficial effect, as also described in more detail above. - Also is previously described for other embodiments, the apparatus described relative to FIGS. 7 and 8 may also pump air from inside to inside, may have a reservoir for fungicide, disinfectant, deodorant, etc., and may be implemented in a broad variety of ways, including having a powered pump rather than a mechanically-operated pump. This innovation provides a product useful in the footwear aftermarket, as it can be used with existing footwear.
- The method and apparatus of the invention is to be allowed the broadest possible interpretation under examination. The spirit and scope of the invention is limited only by the following claims.
