Abstract

An apparatus is disclosed that cools an individual while using a stationary exercise device by supplying cooling air that mostly surrounds the individual, herein called the SurroundCool™ effect. A plurality of air outlets provides a flow of cooling air from a plurality of locations and/or directions to generate the SurroundCool™ effect. Each air outlet is independently adjustable in direction over a range of directions for accommodating various exerciser shapes and sizes. Each air outlet is also independently adjustable in flow rate over a range of flow rates, including fully open and fully closed, so as to help provide a desired level of cooling. Some embodiments allow control of at least one characteristic of the cooling air, including temperature, flow rate, and humidity. In some embodiments, the range of directions is bounded so as to ensure that each cooling air outlet can only be directed at the individual, thereby saving energy.

FIELD
• The invention generally relates to stationary exercise machines, and more specifically to apparatus for cooling individuals while using stationary exercise machines.
BACKGROUND
• Exercise is generally known to have many benefits for individuals of all ages. These benefits include improved cardiovascular health, reduced blood pressure, prevention of bone and muscle loss, maintenance of a healthy weight, improved psychological heath, and many others. However, exercise is generally accompanied by a certain degree of discomfort, including overheating, sweating, fatigue, etc, and this leads to a significant reduction in the amount of exercise undertaken by many individuals, thereby reducing the health benefits derived from exercise.
• Because of weather variability, convenience, and time constraints, exercise often takes place indoors using a stationary exercise machine, such as a stepper, stationary bicycle, elliptical, treadmill, etc. Attempts are sometimes made to increase the comfort of exercising individuals in these environments by optimizing the surrounding temperature. But this can be largely unsatisfactory, because exercisers generally require different degrees of cooling depending on individual physiology and on how long and how vigorously they have been exercising. If the surrounding air is warm enough to be comfortable for individuals just beginning an exercise session, it will likely be too warm for individuals well into a vigorous session. And if the surrounding air is cool enough to be comfortable for an individual who has been exercising vigorously for a significant amount of time, it will likely be too cold for individuals just beginning to exercise.
SUMMARY
• Preferred embodiments provide a number of advantages over prior systems. For example, as recognized by the invention, preferred embodiments employ cooling air to improve the exerciser's experience. Humans generally perspire so that perspiration evaporates off of the skin, removing heat from the exerciser. In some cases, however, excessive perspiration fails to sufficiently evaporate, and thus fails to remove sufficient heat from the exerciser. Excessive perspiration can be uncomfortable for the exerciser, unsanitary, and generally undesirable. Moreover, if sufficient heat is not removed from the exerciser, serious heat-related illnesses can develop, such as heat stress, heat stroke, and nausea.
• Generally, in similar temperature conditions, the presence or absence of airflow, or the particular flow rate, can be the determining factor as to whether the exerciser perspires. In typical exercise environments, such as the common gym, for example, the environment is designed to regulate the temperature of the gym as a whole. Sometimes, free-standing fans are included to help improve the air circulation within the gym.
• However, as described in more detail below, preferred embodiments offer an exerciser a significant improvement in comfort, thereby tending to increase the amount of exercise and the benefits derived therefrom, while also reducing risk of heat-related illnesses and/or excessive sweating. For example, in preferred embodiments, cooling air flow is directed to mostly surround an exerciser, for example a well-conditioned exerciser exercising at maximum aerobic capacity, and this reduces the propensity of the exerciser to perspire by a significant amount. The exerciser does not overheat, and perspires much less, and consequently the exercise is limited primarily by the amount of work the exerciser can do, and not by the discomfort of overheating and the risk of heat-related illness.
• Additionally, preferred embodiments help reduce excessive sweating as well as the symptoms of heat-related illness, or its onset. For example, preferred embodiments tend to reduce nausea while exercising, decrease perspiration dripping over the exercise machine and floor, and reduce nausea after exercising.
• Additionally, for certain exercisers, preferred embodiments eliminate the tendency to perspire entirely. For example, preferred embodiments prevent an average exerciser of modest aerobic capacity, who is not working near their maximum, from any perspiration at all. Eliminating perspiration can provide a number of additional benefits.
• For example, perspiration typically causes body odor. As such, typical exercisers tend to bathe after exercise. But without perspiration, bathing is less necessary, which reduces hot water consumption as exercisers take fewer showers, and shortens the total time required to visit the gym and engage in a workout. Additionally, certain gyms do not have bathing facilities. Eliminating perspiration eliminates the need for an exerciser to exercise hard, get soaked in perspiration, and then drive home. Consequently, gyms could generally maintain higher exercise room temperatures thereby reducing energy costs.
• Additionally, overweight people generally have a body mass relative to surface area that makes heat loss particularly difficult. Preferred embodiments can greatly reduce heat stress in the obese during exercise. Reducing the risk of heat-related illness, and generally making exercise more comfortable, could be the difference that allows and/or encourages certain obese people to exercise effectively, helping them to lose weight.
• Preferred embodiments incorporating the SurroundCool™ effect, described in more detail below, affect a greater surface area of an exerciser than known approaches to cooling an exerciser, thereby improving the transfer of heat away from the exerciser. Additionally, because the SurroundCool™ effect operates upon a greater surface area than known approaches, preferred embodiments provide superior perspiration evaporation.

The apparatus is built into the stationary exercise device, and includes at least one cooling air input that is connectable to a cooling air source, the cooling air source being capable of supplying a flow of cooling air.

In another preferred embodiment, the cooling air source is built in to the stationary exercise device.
• In still another preferred embodiment, the plurality of air outlets are built into at least one extended member of the stationary exercise device, the extended member being extended so as to enable the air outlets to contribute cooling air towards mostly surrounding the exerciser with cooling air. In one embodiment, at least one air outlet is a directable nozzle having a rotatable ring that can be rotated to control the air flow rate, including being able to completely stop air flow from the nozzle. In one embodiment, at least one air outlet is a cooling air outlet with two sets of mutually perpendicular and independently movable louvers, and a tab for directing both sets of louvers.

DETAILED DESCRIPTION
• With reference toFIG. 1, in a preferred embodiment, the apparatus includes anair conditioner100, or other cooling fluid source, that is attached to astationary exercise device102. Theair conditioner100 supplies air that is cooler than the ambient air surrounding thestationary exercise device102 to a coolingair outlet104. In the illustrated embodiment, coolingair outlet104 includes a fan. One skilled in the art will understand that coolingair outlet104 can be configured with or without a fan, or with additional or alternate features, as described in more detail below.
• Coolingair outlet104 serves as the applicator of the cooling air by directing a flow of cooling air toward the front of an individual (not shown) using the device. Warm air resulting from the air cooling process is exhausted from theair conditioner100 through anair duct106.
• In the preferred embodiment ofFIG. 2A, the apparatus includes anair conditioner200 that is not attached to thestationary exercise device102.Air conditioner200 supplies cooling air thorough ahose202 to a coolingair outlet104, which is attached to thestationary exercise device102. In the illustrated embodiment, coolingair outlet104 includes a fan that can be used to control the flow rate of the cooling air leavingcooling air outlet104.FIG. 2B illustrates an embodiment similar to the embodiment ofFIG. 2A, except that coolingair outlet104 is built intostationary exercise device102.
• FIG. 2C illustrates a preferred embodiment that includes anair conditioner200 that is not attached to thestationary exercise device102.Air conditioner200 supplies cooling air thorough ahose202 to a conduit (not shown) in the body ofstationary exercise device102. The conduit directs the received cooling air to a series of coolingair outlets204A-H, which are located along the deck of thestationary exercise device102. Coolingair outlets204A-H direct cooling air upward from below toward an exerciser usingstationary exercise device102. Coolingair outlets204A-D direct cooling air upon the exerciser from along the right side ofstationary exercise device102. Coolingair outlets204E-H direct cooling air upon the exerciser from along the left side ofstationary exercise device102. An aircharacteristic controller206 on the front of thestationary exercise device102 allows the exerciser (not shown) to control the overall flow rate and temperature of the cooling air.
• The preferred embodiment illustrated inFIG. 3 is similar to the embodiment ofFIG. 2B, except that the cooling air source is located outside of the room. Cooling air is supplied through aconnection300 in the wall of the room to a manifold302, and from the manifold302 to a plurality ofstationary exercise devices304. Eachexercise device304 has a coolingair outlet305 that directs the cooling air toward the face, neck, and upper torso of an exerciser usingstationary exercise device102.
• FIG. 3A illustrates an embodiment similar to that ofFIG. 3, except that coolingair outlet305 has been replaced by a plurality of cooling air outlets306. In a preferred embodiment, each cooling air outlet of the plurality of cooling air outlets306 is independently directable so as to collectively direct cooling air toward a plurality of respective portions of the exerciser, consistent with the SurroundCool™ concept described above.
• FIG. 4A andFIG. 4B are functional diagrams that illustrate cooling air outlets in two respective preferred embodiments. InFIG. 4A, coolingair400 flows through aduct402 and exits from a coolingair outlet404 through a set ofair directing louvers406. The direction of thelouvers406 can be controlled by rotating awheel408 located below thelouvers406. InFIG. 4B, cool water flows through apipe410 to aheat exchange device412, having a large surface area.Fan416 pulls coolingair414 across theheat exchange device412, thereby cooling the coolingair418, which is then directed toward an exerciser.
• FIG. 4C illustrates the injection of a coolingmist420 into the coolingair400 ofFIG. 4A. Water travels through ahose422 to aspray nozzle424, which transforms the water intomist droplets420. Themist droplets420 enter amixing chamber426, where themist droplets420 mix with the flow of coolingair400 and are carried through coolingair outlet404 by the coolingair400.
• In the preferred embodiment ofFIG. 5A, a coolingfluid source500 supplies cool liquid through a set ofhoses502 to a heat exchange device andfan504 similar to the device and fan shown inFIG. 4B. The heat exchange device andfan504 is attached to the back of astationary exercise device506, on which an individual508 is exercising, and directs a flow of cooledair510 onto the exercising individual508 from behind. In this embodiment, the source of coolingfluid500 is a closed loop liquid chiller and circulator with a self contained cooling liquid reservoir that is accessible through ahatch512 on the top. Typically, a mixture of water and anti-freeze with anti-corrosion properties is used as the cooling liquid. In other embodiments, the cooling fluid is freon.
• The preferred embodiment ofFIG. 5B uses aliquid chiller500 similar to the chiller ofFIG. 5A, but the chilled liquid is supplied to a plurality of conductive cooling applicators, such as thehandles514, theseat516, and thebackrest518 of thestationary exercise device506. Theexerciser508 using thestationary exercise device506 is cooled by direct conductive thermal contact with the cooled handles514,seat516, andbackrest518. In some situations, it may be desirable to have only conductive cooling applicators, without any cooling air outlets and/or fans to provide convective cooling. Theexerciser508 can manually control these conductive cooling applicators by rotating the handles415 thereby controlling the flow of the cooling liquid to the conductive cooling applicators. For example, by rotating the left one of thehandles514, the flow rate of cooling fluid to theseat516 can be adjusted. By rotating the right one of the handles415, the flow rate of cooling fluid to thehandles514 can be adjusted. Theexerciser508 can adjust the cooling effect of thebackrest518 simply by leaning forward so as to reduce thermal contact with thebackrest518.
• Of course, one of ordinary skill in the art understands that air is a fluid, just as water is a fluid, and therefore, a flow of cooling air can be used to cool the plurality of conductive cooling applicators, such as thehandles514, theseat516, and thebackrest518 of thestationary exercise device506. Using air as the cooling fluid is particularly advantageous for use with cooling air outlets that direct air convectively towards an exerciser. Thus, the same cooling air that is provided by the cooling air outlets can be used to cool the conductive cooling applicators by flowing through the conductive cooling applicators.
• FIG. 5C illustrates the cooling of the handles by the chilled liquid in the preferred embodiment ofFIG. 5B. The chilled liquid flows into and up supportingarm518, which supports the twohand grips514, through the twohand grips514, and then down the other supportingarm520. In this illustrated embodiment, the twohand grips514 are metal and provide good thermal contact with the chilled liquid. The interiors of the supportingarms518 and520, and the cross brace522 between the twohand grips514 are thermally insulated so as to avoid warming of the chilled liquid as it flows up to and down from the handles, and to avoid water condensation on the supportingarms518 and520 and the cross brace522.
• Various preferred embodiments include both cooling air outlets which provide flows of coolingair504, andconductive cooling applicators514,516,518 which provide cooling by thermal conduction due to a flow of cooling fluid (such as cooling air) flowing therewithin, whereby the exerciser can select and control which types of cooling are to be applied, and how much of each. Of course, it is also possible to include only theconductive cooling applicators514,516,518 which provide cooling by thermal conduction due to a flow of cooling air or water flowing therewithin, whereby the exerciser can select and control how much conductive cooling is desired.
• The embodiment ofFIG. 5D uses aliquid chiller500 similar to the chiller ofFIG. 5A, but the chilled liquid is supplied to coolingair outlets504A-D, wherein air is cooled by the chilled liquid in a manner similar to the outlet ofFIG. 4B, the cooling air outlets being part of thebackrest510 of thestationary exercise device506. Coolingair outlets504A-D direct cooling air frombackrest510 toward the back, head, and neck of theexerciser508.
• In the embodiment ofFIG. 6A,air conditioner608 supplies cooling air through aninput hose606 tostationary exercise device600. A plurality of coolingair outlets610A-H direct cooling air to mostly surround anexerciser602. Anupward extension612 is coupled to arear section604 ofstationary exercise device600.Upward extension612 includes coolingair outlets610A-B, which direct air toward the rear ofexerciser602.
• Similarly,front extension616 is built into a front section ofstationary exercise device600. The front section ofstationary exercise device600 includes conduits (not shown) internal to thestationary exercise device600 that carry air fromhose606 through tofront extension616 and out through coolingair outlet610D, which directs cooling air toward the face, neck, and upper torso ofexerciser602. The front section ofstationary exercise device600 also includes coolingair outlets610E and610F, which direct cooling air toward the front middle torso ofexerciser602. The front section ofstationary exercise device600 also includes coolingair outlets610G and610H, which direct cooling air toward the legs and feet ofexerciser602.
• The plurality of cooling air outlets ofFIG. 6A cooperate to create a SurroundCool™ personal cooling environment for the exerciser. As described in more detail with respect to the embodiments disclosed herein, SurroundCool™ systems use multiple cooling air outlets to project multiple flows of cooling air directly upon an exerciser so as to efficiently cool the exerciser without wasting energy by cooling the general environment around the exerciser. In some embodiments, the plurality of cooling air flows provided by SurroundCool™ systems cannot be directed away from the exerciser's body. Instead, in these embodiments the exerciser can only restrict or block the flow of cooling air. As such,SurroundCool™ systems in these embodiments thereby improve energy efficiency, by forcing the user to restrict or block flows of cooling air when they are no longer desired, rather than wastefully diverting unwanted cooling air flows away from the body and into the general environment.
• For example, in the illustrated embodiment ofFIG. 6A, coolingair outlet610D, directly cools the face and upper front body of theexerciser602, while coolingair outlets610E-H directly cool the lower front portion of theexerciser602. At the same time, coolingair outlets610A-C directly cool the rear portion of theexerciser602. As described in more detail below, these cooling air outlets provide limited user-controlled direction within a restricted range of directions, for example to direct cooling air according to an exerciser's body size and shape. The ranges of direction adjustment are restricted so as to always direct some portion of the cooling air onto the exerciser. In other embodiments, the stationary exercise device can request from the exerciser, or automatically determine, the particular exerciser's body weight and/or height. Using the requested or determined information, preferred embodiments restrict the ranges of motion of the user-controlled cooling air outlets so as to ensure that a portion of each air flow always contacts at least a portion of the exerciser.
• In the preferred embodiment ofFIG. 6B,air conditioner608 that supplies cooling air through aninput hose606 tostationary exercise device600, as inFIG. 6A. However, instead of an upward rear extension having a plurality of cooling air outlets,stationary exercise device600 ofFIG. 6B includes a singleforward extension612 coupled torear section604.Forward extension612 includes a singlecooling air outlet610A, which directs coolingair612 toward the rear ofexerciser602.
• Similarly,front extension616 couples to a front section ofstationary exercise device600. The front section ofstationary exercise device600 includes conduits (not shown) internal to thestationary exercise device600 that carry air frominput hose606 through tofront extension616 and out through coolingair outlet610D, which directs cooling air toward the face, neck, and upper torso ofexerciser602. The front section ofstationary exercise device600 also includes coolingair outlets610E and610F, which direct cooling air toward the front middle torso ofexerciser602. The front section ofstationary exercise device600 also includes coolingair outlets610G and610H, which direct cooling air toward the legs and feet ofexerciser602.
• FIG. 6C illustrates cooling air projections associated with the coolingair outlets610A,610D, and610E-H ofFIG. 6B.Exerciser602 is not shown for clarity of illustration. Coolingair outlet610A directs cooling air generally toward the area indicated by coolingair projection612A. Coolingair outlet610D directs cooling air generally in the area indicated by coolingair projection612D. Coolingair outlet610F directs cooling air generally in the area indicated by coolingair projection612F. Coolingair outlet610G directs cooling air generally in the area indicated by coolingair projection612G. Coolingair outlet610H directs cooling air generally in the area indicated by coolingair projection612H.
• Additionally,FIG. 6C illustrates, using the cooling air projections, how the collective air flow from coolingair outlets610A-H mostly surround theexerciser602 with cooling air. Further, the arrangement of the cooling air outlets and cooling air projections suggests the impression of being in a vehicle cockpit to theexerciser602.
• FIG. 6D illustrates, using the cooling air projections, how the collective air flow from coolingair outlets610D-H mostly cover the front ofexerciser602 with cooling air. Similarly,FIG. 6E illustrates, using the cooling air projections, how the collective air flow from rear cooling air outlets, here coolingair outlet610A, mostly covers the rear ofexerciser602 with cooling air.
• FIG. 7A illustrates an exemplarycooling air outlet700 that receives cooling air from aconnector702 that connects coolingair outlet700 to ahose704. Hose703 connects to a cooling air supply (not shown). Coolingair outlet700 is rotatably coupled toconnector702, so that an exerciser can manually adjust the cooling air flow exiting coolingair outlet700.
