     FIELD OF THE INVENTION 
       [0003]    This invention relates generally to exercise equipment, and particularly to cooling devices for use during exercise. 
       BACKGROUND OF THE INVENTION 
       [0004]    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. 
         [0005]    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. 
         [0006]    Because of weather variability, convenience, and time constraints, exercise often takes place indoors using a stationary exercise device such as a stepper, stationary bicycle, elliptical machine, treadmill, free weight machine, exercise ball, or exercise mat, for example. 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 not exercising or just beginning to exercise. 
         [0007]    Although fans are known to be used for cooling an exerciser, they work by helping sweat to evaporate, which provides evaporative cooling only after the exerciser has heated up enough to have started sweating. Such heat and sweating can be felt as uncomfortable, leading to a significant reduction in the amount of exercise undertaken by the exerciser, 
       SUMMARY OF THE INVENTION 
       [0008]    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&#39;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 fully 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. 
         [0009]    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. 
         [0010]    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 so as to mostly surround an exerciser, for example a well-conditioned exerciser exercising at maximum aerobic capacity, and this reduces by a significant amount the propensity of the exerciser to perspire. 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. 
         [0011]    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. 
         [0012]    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. 
         [0013]    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. 
         [0014]    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. 
         [0015]    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.

     DETAILED DESCRIPTION 
       [0107]    With reference to  FIG. 1 , in a preferred embodiment, the apparatus includes an air conditioner  100 , or other cooling fluid source, that is attached to a stationary exercise device  102 . The air conditioner  100  supplies air that is cooler than the ambient air surrounding the stationary exercise device  102  to a cooling air outlet  104 . In the illustrated embodiment, cooling air outlet  104  includes a fan. One skilled in the art will understand that cooling air outlet  104  can be configured with or without a fan, or with additional or alternate features, as described in more detail below. 
         [0108]    Cooling air outlet  104  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 the air conditioner  100  through an air duct  106 . 
         [0109]    In the preferred embodiment of  FIG. 2A , the apparatus includes an air conditioner  200  that is not attached to the stationary exercise device  102 . Air conditioner  200  supplies cooling air thorough a hose  202  to a cooling air outlet  104 , which is attached to the stationary exercise device  102 . In the illustrated embodiment, cooling air outlet  104  includes a fan that can be used to control the flow rate of the cooling air leaving cooling air outlet  104 .  FIG. 2B  illustrates an embodiment similar to the embodiment of  FIG. 2A , except that cooling air outlet  104  is built into stationary exercise device  102 . 
         [0110]      FIG. 2C  illustrates a preferred embodiment that includes an air conditioner  200  that is not attached to the stationary exercise device  102 . Air conditioner  200  supplies cooling air thorough a hose  202  to a conduit (not shown) in the body of stationary exercise device  102 . The conduit directs the received cooling air to a series of cooling air outlets  204 A-H, which are located along the deck of the stationary exercise device  102 . Cooling air outlets  204 A-H direct cooling air upward from below toward an exerciser using stationary exercise device  102 . Cooling air outlets  204 A-D direct cooling air upon the exerciser from along the right side of stationary exercise device  102 . Cooling air outlets  204 E-H direct cooling air upon the exerciser from along the left side of stationary exercise device  102 . An air characteristic controller  206  on the front of the stationary exercise device  102  allows the exerciser (not shown) to control the overall flow rate and temperature of the cooling air. 
         [0111]    The preferred embodiment illustrated in  FIG. 3  is similar to the embodiment of  FIG. 2B , except that the cooling air source is located outside of the room. Cooling air is supplied through a connection  300  in the wall of the room to a manifold  302 , and from the manifold  302  to a plurality of stationary exercise devices  304 . Each exercise device  304  has a cooling air outlet  305  that directs the cooling air toward the face, neck, and upper torso of an exerciser using stationary exercise device  102 . 
         [0112]      FIG. 3A  illustrates an embodiment similar to that of  FIG. 3 , except that cooling air outlet  305  has been replaced by a plurality of cooling air outlets  306 . In a preferred embodiment, each cooling air outlet of the plurality of cooling air outlets  306  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. 
         [0113]      FIG. 4A  and  FIG. 4B  are functional diagrams that illustrate cooling air outlets in two respective preferred embodiments. In  FIG. 4A , cooling air  400  flows through a duct  402  and exits from a cooling air outlet  404  through a set of air directing louvers  406 . The direction of the louvers  406  can be controlled by rotating a wheel  408  located below the louvers  406 . In  FIG. 4B , cool water flows through a pipe  410  to a heat exchange device  412 , having a large surface area. Fan  416  pulls cooling air  414  across the heat exchange device  412 , thereby cooling the cooling air  418 , which is then directed toward an exerciser. 
         [0114]      FIG. 4C  illustrates the injection of a cooling mist  420  into the cooling air  400  of  FIG. 4A . Water travels through a hose  422  to a spray nozzle  424 , which transforms the water into mist droplets  420 . The mist droplets  420  enter a mixing chamber  426 , where the mist droplets  420  mix with the flow of cooling air  400  and are carried through cooling air outlet  404  by the cooling air  400 . 
         [0115]    In the preferred embodiment of  FIG. 5A , a cooling fluid source  500  supplies cool liquid through a set of hoses  502  to a heat exchange device and fan  504  similar to the device and fan shown in  FIG. 4B . The heat exchange device and fan  504  is attached to the back of a stationary exercise device  506 , on which an individual  508  is exercising, and directs a flow of cooled air  510  onto the exercising individual  508  from behind. In this embodiment, the source of cooling fluid  500  is a closed loop liquid chiller and circulator with a self contained cooling liquid reservoir that is accessible through a hatch  512  on the top. Typically, a mixture of water and anti-freeze with anti-corrosion properties is used as the cooling liquid. The cooling fluid could also be Freon. 
         [0116]    The preferred embodiment of  FIG. 5B  uses a liquid chiller  500  similar to the chiller of  FIG. 5A , but the chilled liquid is supplied to a plurality of conductive cooling applicators, such as the handles  514 , the seat  516 , and the backrest  518  of the stationary exercise device  506 . The exerciser  508  using the stationary exercise device  506  is cooled by direct conductive thermal contact with the cooled handles  514 , seat  516 , and backrest  518 . 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. The exerciser  508  can manually control these conductive cooling applicators by rotating the handles  415  thereby controlling the flow of the cooling liquid to the conductive cooling applicators. For example, by rotating the left one of the handles  514 , the flow rate of cooling fluid to the seat  516  can be adjusted. By rotating the right one of the handles  415 , the flow rate of cooling fluid to the handles  514  can be adjusted. The exerciser  508  can adjust the cooling effect of the backrest  518  simply by leaning forward so as to reduce thermal contact with the backrest  518 . 
         [0117]    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 the handles  514 , the seat  516 , and the backrest  518  of the stationary exercise device  506 . 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. 
         [0118]      FIG. 5C  illustrates the cooling of the handles by the chilled liquid in the preferred embodiment of  FIG. 5B . The chilled liquid flows into and up supporting arm  518 , which supports the two hand grips  514 , through the two hand grips  514 , and then down the other supporting arm  520 . In this illustrated embodiment, the two hand grips  514  are metal and provide good thermal contact with the chilled liquid. The interiors of the supporting arms  518  and  520 , and the cross brace  522  between the two hand grips  514  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 supporting arms  518  and  520  and the cross brace  522 . 
         [0119]    Various preferred embodiments include both cooling air outlets which provide flows of cooling air  504 , and conductive cooling applicators  514 ,  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 the conductive cooling applicators  514 ,  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. 
         [0120]    The embodiment of  FIG. 5D  uses a liquid chiller  500  similar to the chiller of  FIG. 5A , but the chilled liquid is supplied to cooling air outlets  504 A-D, wherein air is cooled by the chilled liquid in a manner similar to the outlet of  FIG. 4B , the cooling air outlets being part of the backrest  510  of the stationary exercise device  506 . Cooling air outlets  504 A-D direct cooling air from backrest  510  toward the back, head, and neck of the exerciser  508 . 
         [0121]      FIG. 6A  illustrates an apparatus for cooling an exerciser, while the exercise is using treadmill  600 . Treadmill  600  can be any treadmill having a structure, such as support legs  608 A,  608 B, that can be used to attach the apparatus to treadmill  600 . For example, in the illustrated embodiment, attachments  606  support the apparatus. Generally, the apparatus includes extended cooling structures having a cooling air input and a plurality of cooling air outlets. 
         [0122]    Specifically, the apparatus includes extended cooling structures  602 A,  602 B and cooling air conduits  610 A,  610 B, that connect extended cooling structures  602 A,  602 B to a cooling air source  612 . In this illustrated embodiment, extended cooling structures  102 A,  102 B include air outlets  104 A- 1041 , which direct cooling air received from the cooling air source  112  to various parts of the exerciser&#39;s body. In alternate embodiments, extended cooling structures  102 A,  1028  can include a plurality of air outlets arranged in other configurations. In the illustrated embodiment, cooling air conduits  610 A,  610 B are hoses connected between the cooling air source  612  and the extended cooling structures  602 A,  602 B. In alternate embodiments, extended cooling structures  602 A,  602 B include cooling air inputs that can connect with a variety of cooling air sources. 
         [0123]    For example, cooling air source  612  can be a high-velocity cooling system, or a central air conditioning system, or a window air conditioner with an adapter, or any other suitable cooling air source. 
         [0124]    Cooling air source  612  and conduits  610 A,  610 B can be any design and size sufficient to function as described in this document. For example, in one embodiment, conduits  610 A,  610 B are about  4 ″ in diameter, and cooling air source  612  includes a  14 ″ radius high-speed fan able to provide sufficient air flow to allow a person using treadmill  600  to adjust air outlets  604 A- 6041  to move air in a desired configuration for comfortable exercise. Alternatively, a high-velocity cooling air source provides cooling air to cooling air source  612  through conduits  2 ″ in diameter, and cooling air source  612  provides the cooling air to extended cooling structures  602 A,  602 B through conduits less than  4 ″ in diameter, providing cooling air at a rate and pressure useable by the exerciser via the extended cooling structures  602 A,  602 B. 
         [0125]      FIG. 6B  is a perspective view of a stationary exercise device having attached extended cooling structures, the extended cooling structures having upper and lower cooling air outlets  604 A-L. As shown, the cooling air outlets  604 A-L can be round air outlets, as described below in more detail with respect to  FIGS. 9A-E . Alternatively, cooling air outlets  604 A-L can be nozzles such as are commonly found above the passenger seats in typical commercial aircraft. Generally, cooling air outlets  604 A-L allow the exerciser to independently and manually control the direction and/or flow rate of the cooling air directed at the exerciser from each cooling air outlet individually. 
         [0126]      FIG. 6C  is a perspective view of several stationary exercise devices  600 A-D, each equipped with attached extended cooling structures as shown in  FIG. 6A , the extended cooling structures being connected to a common remote cooling air source. In some embodiments, the extended cooling structures each connect individually to a central manifold or trunk, such as trunk  616 , for example. In alternate embodiments, the extended cooling structures each connect individually to the cooling air source. Generally, the cooling air source is able to provide sufficient cooling air flow to allow a person using treadmill  600  to adjust air outlets  604 A- 6041  so as to move air in a desired SurroundCool™ configuration for comfortable exercise. 
         [0127]      FIGS. 7A and 7B  illustrate another embodiment of a cooling apparatus attached to a treadmill  600 . Extended cooling structures  700 A,  700 B each include air outlets  704 A- 704 G, each of the air outlets  704 A- 704 G being individually adjustable so as to provide a desired air flow surround pattern for a person using the treadmill  600 . 
         [0128]    The extended cooling structures  700 A,  700 B are supported partially by support legs  702 A,  702 B that are located and sized so as to help support the portion of each of the extended cooling structures  700 A,  700 B that is farthest from where it is attached to the treadmill  600 . A strap  706 , cooperative with a sigmoidal support  710 , supports the portion of each of the extended cooling structures  700 A,  700 B that is closest to the treadmill  600  to respective treadmill supports  608 A,  608 B, as shown in  FIG. 7B . 
         [0129]    As shown in  FIG. 7B , the sigmoidal support  710  attaches to the extended cooling structure  700 A via attachment hardware  708  (also shown in  FIG. 7A ). Sigmoidal support  710  is also attached to the strap  706  via support  712 . The weight of the extended cooling structure  700 A causes the foot  714  to press against the support leg  608 A of the treadmill  60 , thereby attaching, supporting, and stabilizing the extended cooling structure  700 A. Thus, using a strap  706  and a sigmoidal support  710 , each extended cooling structure  700 A,  700 B can be easily attached to a standard treadmill. 
         [0130]    With reference to  FIG. 8A , some embodiments of the present invention include a plurality of free-standing extended cooling structures  810 ,  812 ,  814 ,  816 , each of which receives cooled and/or dried air through hoses  610 A-F connected to a cooling air source  612 , and each of which includes a plurality of cooling air outlets  816 A-D. The extended cooling structures  810 - 816  have been arranged in the embodiment of  FIG. 8A  so as to surround an exerciser  822  while exercising on a NordicTrack™ ski exercise machine. The extended cooling structures  810 - 816  are easily moved and rearranged so as to surround the exerciser as desired while performing any type of exercise on a device of any size and shape, such as lifting free weights, which requires the exerciser&#39;s arms to be fully outstretched, using a device which exercises the shoulders and/or back muscles, or performing crunches on a ball or planks on a mat. 
         [0131]    In the embodiment of  FIG. 8A , the extended cooling structures  810 ,  812 ,  814 ,  816  are each supported by two legs, each leg having an upper portion  818  which is telescopically inserted into a lower portion  816  and locked in place at a desired height by a locking knob  820 . Graduated marks are included on the upper portion  818  so as to facilitate adjustment of all of the legs to the same height. The heights of the extended cooling structures  810 - 816  are thereby easily adjustable, so as to provide optimal cooling for people of all heights and/or for exercise activities which take place at differing heights. For example, the extended cooling structures  810 - 816  can be raised or lowered so as to accommodate an exerciser of any height, whether performing an exercise in a sitting or prone position, such as crunches on an exercise ball or mat on the floor, or exercising in a fully upright position. While  FIG. 8A  illustrates the embodiment surrounding a single exerciser, the embodiment can also accommodate more than one exerciser. 
         [0132]      FIG. 8B  illustrates the embodiment of  FIG. 8A  surrounding an exerciser  824  performing aerobic exercises on an exercise stool  826 . Various other types of exercise devices are provided outside of the exercise environment as examples of some of the exercise devices that can be utilized in this environment, including barbells  828 , a stretching/elastic cord with handles  830 , an exercise ball  832 , and an exercise mat  834 . These are simply examples of a very wide variety of types of exercise devices which can easily be brought into and subsequently removed from the region surrounded by the extended cooling structures  810 - 816 . Further, for certain exercises, such as exercises performed while sitting on the ball  832  or while lying on the mat  834 , the exerciser  824  may wish to accordingly lower the heights of the extended cooling structures  810 - 816 . 
         [0133]      FIGS. 9A-9E  show an embodiment of cooling air outlet  900  similar to many of the cooling air outlets mentioned above. Of course, air-flow rate and air-flow direction adjustment mechanisms of a different form than, but similar function to, exemplary cooling air outlets  900  each with adjustment knob  904  can be used to provide individually adjustable air flow to a person using a stationary exercise device without departing from the scope of the invention. Cooling air outlets  900  are each attached to an air supply  906  via a connector  902 . 
         [0134]    Adjustment knob  904  can be moved to direct air flow from air cooling air outlet (also called a “vent”)  900 , with the airflow generally coaxial with the direction of adjustment knob  904 . For example, adjustment knob  904  can be pushed upward, as shown in  FIG. 9B , resulting in a airflow in a more upward direction than that in  FIG. 9A . Similarly, the airflow of air outlet  900  in  FIG. 9C  will be more downward, the airflow of air outlet  900  in  FIG. 9D  rightward, and the airflow of air outlet  900  in  FIG. 9E  leftward. 
         [0135]    Turning to  FIG. 10A , three treadmills  600 A,  600 B,  600 C are each flanked by a pair of extended, separately supported cooling structures selected from extended cooling structures  1000 ,  1002 ,  1004 ,  1006 . The two outer extended cooling structures  1000 ,  1006  include air outlets  1000 A- 1000 D,  1006 A- 1006 D, respectively, only on an inward-facing side so as to provide airflow to a person on the nearest treadmill  600 A and  600 C. The two inner extended cooling structures  1002 ,  1004  each include air outlets on both sides, so as to provide individually controllable airflow for each of the treadmills flanking each extended cooling structure. The extended cooling structures  1000 ,  1002 ,  1004 ,  1006  are supplied with air through conduits  1010 A- 1010 D from a supply line  1008 , which can be attached to an HVAC system or to a large fan box, or any other conditioned air supply device. 
         [0136]    Although  FIG. 10A  illustrates the embodiment applied to a plurality of exercise devices where each exercise device is situated between two extended cooling structures with air outlets facing each exercise device, this embodiment can also be used along only one side of a single exercise device, or between two exercise devices, thereby providing cooling to one side of each exerciser. Also note that each extended cooling structure in  FIG. 10A  is free-standing, and not attached to the machine used by the exerciser. Consequently, this embodiment can be used with existing exercise machines without any modification to the exercise machine. 
         [0137]    Referring to  FIG. 10B , the cooling air source  612  is now present in the room, and the legs  1036  support a “spine”  1030  that supports a plurality of extended cooling structures  1012 - 1020  of the cooling apparatus, the legs  1036  being bolted to the floor, each leg having a very thin base so as to be practically flush with the floor, the base  1034  of each leg also having a very small footprint so as to ensure that it will not interfere with foot traffic near the apparatus. The spine  1030  also supports a plurality of front-facing shorter extended cooling structures  1022 ,  1024 ,  1026 ,  1028 , each of which includes two front-facing air outlets for cooling the front of an exerciser. 
         [0138]    Additional front cooling air outlets  1022 A- 1022 B,  1024 A- 1024 B,  1026 A- 1026 B,  1028 A- 1028 B are shown on the plurality of front-facing shorter extended cooling structures  1022 ,  1024 ,  1026 ,  1028 , respectively. Supply conduit  1032  feeds a central plenum within the spine  1030 , which then supplies cooling air to each of the extended cooling structures and air outlets, so as to provide cooled and/or dried air for individuals using treadmills  600 A- 600 D. 
         [0139]    Referring to  FIG. 10C , individual conduits  1010 A- 1010 D separately supply the respective extended cooling structures that substantially surround each treadmill. In particular, the cooling air source  612  supplies cooling air via the main hose  1032  to a main feeder conduit  1008 . The main feeder conduit supplies a flow of cooling air via individual conduits  1010 A,  10108 ,  1010 C,  1010 D to each of a connected series of spine modules  1030 A- 1030 D. Each of the spine modules  1030 A- 1030 D is mechanically connected to a respective treadmill  600 A- 600 D, and to two extended cooling structures  1012 ,  1014 ,  1016 ,  1018  which each receive cooling air from the spine modules, for substantially surrounding an exerciser using a treadmill  600 A- 600 D with cooling air. Each extended cooling structure  1012 ,  1014 ,  1016 ,  1018  includes air outlets that face the exerciser using the treadmill  600 A. The front-facing air outlets  1022 A and  10228 , as well as the lower front air outlet  1022 C, also receive cooling air from a respective spine module  1030 A- 1030 D, and contribute to substantially surrounding the exerciser with cooling air. Note that additional spine modules can be added, along with corresponding extended cooling structures and front-facing air outlets, as more treadmills are added to the treadmills shown. In fact, only one additional extended cooling structure and respective front-facing air outlets are needed for each additional spine module. 
         [0140]    Thus,  FIG. 10C  is a top view of a preferred embodiment in which a plurality of stationary exercise devices  600 A-D are cooled by a plurality of cooling modules which are attached to the stationary exercise devices and which interconnect to form a continuous series of modules. Each cooling modular unit includes a spine module  1030 A-D which is connected by a hose  1010 A-D to a cooling air supply manifold  1008  which receives cooled and/or dehumidified air from a cooling air source  612  through a main hose  1032 . Cooling air is directed onto exercisers from the front by air outlets  1022 A- 1028 B included in the spine modules  1030 A-D. Cooling air is directed onto the sides of exerciser&#39;s using the stationary exercise devices  600 A-D by extended cooling structures  1012 - 1020  which function as manifolds, and extend between the stationary exercise devices  600 A-D. Extended cooling structures  1012 ,  1020  are located on the ends of the series of modules, and include cooling air outlets only on their inward-facing surfaces, and supply cooling air to only one exercise device  600 A,  600 D. Inner extended cooling structures  1014 - 1018  include cooling air outlets on both sides, and supply cooling air to the stationary exercise devices which are located on either side  600 A-D. Note that additional stationary exercise devices can be accommodated by the series simply by adding additional spine modules  1030 A-D and inner extended cooling structures  1014 - 1018 . 
         [0141]      FIG. 10D  is a top view of a single stationary exercise device  600  cooled by a single cooling modular unit  612  of the embodiment of  FIG. 10C . Since there is only one exercise device  600 , the modular unit includes a single spine module  1030  and a pair of outer extended cooling structures  1012 ,  1020 , without any inner extended cooling structures  1014 - 1018 . Also included are the front-facing air outlets  1022 A,  10228 ,  1022 C of the front extended cooling structure  1022 . The hose  1032  provides the cooling air to the single spine module  1030 , which is in air-flow communication with the extended cooling structures  1012  and  1020 , and with the front extended cooling structure  1022 . 
         [0142]      FIG. 10E  is a front perspective view of the embodiment of  FIG. 10D . 
         [0143]      FIG. 10F  is a front perspective view of an embodiment similar to  FIG. 10E , but wherein the cooling modular unit is not attached to the stationary exercise device  600 , but which is instead free standing and supported on legs  1036  that support the extended cooling structures  1012 ,  1020 , and the spine module  1030  that connects, and is in air-flow communication with, the extended cooling structures  1012 ,  1020 . Thus, the treadmill can be equipped with a SurroundCool™ system without any modification to the treadmill itself. 
         [0144]      FIG. 10G  is a side view of the stationary exercise device  600  of  FIG. 10D , without the cooling modular unit attached, where the cooling modular unit includes the single spine module  1030 , which is connected to and in air-flow communication with the extended cooling structures  1012  and  1020 , and with the front extended cooling structure  1022   
         [0145]      FIG. 10H  is a side view of the stationary exercise device  600  of  FIGS. 10D and 10G , with the cooling modular unit attached, in air-flow communication with a cooling air supply line  1008  via hose  1010 . The cooling modular unit includes the extended cooling structure  1020 , showing the side without air outlets. 
         [0146]      FIG. 10I  is a side view of the stationary exercise device  600  of  FIG. 10D , with the nearest extended cooling structure  1020  removed, so that the farther extended cooling structure  1012  and it&#39;s air outlets, and the remainder of the cooling modular unit and the exercise device  600 , can be more clearly seen. The air outlets  1012 A- 1012 D and the air outlets  1022 A- 1022 C can be manually adjustable regarding air flow direction and air flow rate. Or, they can be fixed and non-adjustable, or just have an on/off adjuster, without any control over air flow rate or direction. In other embodiments, the adjustability of the air flow direction can be restricted so as to ensure that the cooling air flow can only be directed upon the exerciser, as opposed to out into the room generally. This feature is advantageously combined with an air flow rate adjustment that allows the exerciser to restrict or stop the flow of cooling air from a particular air outlet if the cooling air is causing discomfort somewhere on the exerciser&#39;s body. The air flow rate adjustment can adjust the air flow rate from fully on to fully off. Alternatively, it is useful to include louvers that can be adjusted such that when they are adjusted to change their direction enough to take a flow of cooling air off of the body of the exerciser, it will stop the flow of cooling air entirely. These features ensure that the flow of cooling air will either be on the person or shut off, which means that the cooling air is only used to cool the exerciser, and not just the room, thereby saving energy. These remarks regarding air outlets are applicable to all embodiments of the invention described herein. 
         [0147]      FIG. 10J  is a top exploded view of the embodiment of  FIG. 10C-10F , and  10 H- 10 I, with the extended cooling structures  1012 ,  1020  and the front facing air outlets  1026 A- 1026 C of front extended cooling structure  1022 , which in this embodiment is integral with the spine module  1030  and shown separated from the stationary exercise device  600 . The locations of the cooling air outlets  1012 A-H of the extended cooling structures  1012 ,  1020  are indicated. The full shape of the front-facing extended cooling structure  1022  can be seen, including the extensions that represent the spine module  1030  which interlocks with the extended cooling structures  1012 ,  1020 , and can interlock with other spine modules attached to other exercise machines, as needed. 
         [0148]      FIG. 10K  is similar to  FIG. 10B , except that the modular “spine”  1030 A- 1030 D of the cooling modules is mounted to a wall. Also, the front-facing extended cooling structures  1022 ,  1024 ,  1026 ,  1028 , each having a pair of front-facing air outlets, are respectively attached to the spine modules  1030 A- 1030 D, which are cooperative with treadmills  600 A- 600 D. 
         [0149]      FIG. 10L  is a top view of  FIG. 10K , showing the modular “spine”  1030 A- 1030 D of the cooling modules, and the wall to which it&#39;s mounted. Also, shown is a top view of the front-facing extended cooling structures  1022 ,  1024 ,  1026 ,  1028 , each having a pair of front-facing air outlets, and that they are respectively attached to the spine modules  1030 A- 1030 D, which are cooperative with treadmills  600 A- 600 D. 
         [0150]      FIG. 10M  is similar to  FIG. 10L , except that instead of being mounted to the wall, the interconnected cooling modules are free-standing, supported by the six legs  1034 . All other features are as explained above. 
         [0151]      FIG. 10N  is similar to the cooling apparatus of  FIG. 10K , except it is used with elliptical machines  1038 A- 1038 D, and the spine attached to the wall is used only for mechanical support of the extended cooling structures  1012 - 1020 , while the cooling air is connected separately to each of the extended cooling structures  1012 - 1020  by means of a plurality of separate hoses connected to a cooling air distribution manifold  1008 . 
         [0152]      FIG. 10O  is essentially the cooling apparatus of  FIG. 10B , except used with elliptical machines  1038 A- 1038 D. The support legs have been bolted flat to the floor so as to reduce their footprint. 
         [0153]      FIG. 11  is a perspective view of single elliptical machine  1100  having a pair of extended cooling structures  1102 A and  1102 B attached to a central post  1110  of the machine  1100 . Each extended cooling structure  1102 A and  1102 B has five cooling air outlets  1104 A- 1104 E and  1104 F- 11041 , respectively. This single elliptical machine  1100  includes a built-in air conditioner with an air intake port  1105 . Each of the cooling air outlets, such as the cooling air outlet  1104 A, includes a manual control for adjusting the cooling air flow rate  408 A, from full on to full off, and all flow rates between. The cooling air outlet  1104 A also includes a manual control for adjusting the direction of air flow  408 B which controls the louvers  406 . The direction of flow can be adjusted up and down, and/or right and left. 
         [0154]    In some embodiments, the directional adjustments  408 B are limited so as to ensure that the cooling air must be directed only to some portion of the user&#39;s body. This requires the user to adjust the intensity of the cooling by adjusting the flow rate of the cooling air using the adjustment wheel  408 A of each of the cooling air outlets, thereby preventing cooling air (and energy) from being wasted by deflecting the cooling air into the room without directly cooling the exerciser. In other embodiments, only the direction of the air  408 B can be adjusted, and in some of these embodiments the flow of cooling air can be stopped by moving the direction adjustment  408 B to an extreme position, whereby the lovers  406  are closed against each other. While the cooling air outlets shown in  FIG. 11  are essentially rectangular, in various preferred embodiments, the cooling air outlets are round, or take on other shapes and control configurations known in the art. 
         [0155]    Brackets  1106 A and  1106 B attach the extended cooling structures  1102 A and  1102 B to the central post  1110  of the machine  1100  so that either one of the extended cooling structures  1102 A and/or  1102 B can be raised by rotating at least one of the brackets  1106 A and  1106 B, as shown in  FIGS. 13B-13E , and  14 , so as to allow an exerciser to more easily get on and off of the machine  1100  from either side. 
         [0156]    Turning now to  FIG. 12A , a vertical extended cooling structure  1200  is attached to a central post of an elliptical machine  1100  by a strap  1108  and support brace  1204 . The extended cooling structure  1200  has two air outlets  1202 A and  1202 B that are supplied with cooling air via the air conduit  1032 . 
         [0157]      FIG. 12B  illustrates a similar embodiment with two vertical extended cooling structures  1200 A,  1200 B with additional air outlets  1202 C- 1202 D. 
         [0158]      FIG. 12C  shows an embodiment having two vertical extended cooling structures  1200 A and  1200 B, except they are attached by straps  1208 A and  1208 B to stationary grips  1210 A and  1210 B, respectively, of elliptical machine  1100 . The straps  1208 A,  1208 B include frictional pads which press against the stationary grips  1210 A,  1210 B and provide frictional attachment thereto. The vertical extended cooling structures  1200 A,  1200 B are thereby easily mounted and dismounted to the elliptical machine  1100 , without damaging or cosmetically blemishing the elliptical machine  1100 . 
         [0159]      FIGS. 13A and 13B  illustrate an embodiment of a cooling device attached to an exercise bicycle, the cooling device having extended cooling structures  1302 A and  1302 B each having air outlets  1304 A- 1304 H, which surround exerciser  1301  with individually adjustable conditioned air, in a similar manner to any of the embodiments discussed above. As shown in  FIG. 13B , the extended cooling structures  1302 A and  1302 B can be rotationally coupled to the exercise cycle  1300  to allow the exerciser easy access to exercise cycle  1300 . 
         [0160]      FIG. 13C  illustrates the rotational coupling of the extended cooling structures  1302 A and  1302 B. Strap  1308  can include support flanges  1312 A and  1312 B. Pairs of detent plates for each extended cooling structure, detent plates  1314 A and  1316 A for extended cooling structure  1302 A and detent plates  1314 B and  1316 B for extended cooling structure  1302 B, can provide sufficient frictional engagement with cooperative detent indentions and protrusions to allow extended cooling structures  1302 A and  1302 B to rotate, with cooperative detent plates rotating and holding at different rotational positions as the detents engage. 
         [0161]      FIGS. 13D-13E  show two positions of the extended cooling structure  13028  in different rotational positions. In the  FIGS. 13D-13E , extended cooling structures  1302 A and  1302 B are connected to the detent plates through support braces  1306 A and  1306 B, respectively. 
         [0162]      FIG. 14  illustrate an embodiment similar to that of  FIG. 10O , except that each extended cooling structure  1012 ,  1014 ,  1016 ,  1018 , 1020  is able to swing up so as to allow easy access to each of the elliptical machines  1038 A- 1038 D. 
         [0163]    While the description above generally focuses on extended cooling structures having a plurality of air outlets, the extended cooling structures being attached to an exercise machine and/or supported by the floor, such extended cooling structures can also be partially suspended from the ceiling. Also, the extended cooling structures can be connected to a free-standing air conditioner, a window air conditioner, an air supply box, or can be connected to a central HVAC system, or any other suitable air supply system, such as a high velocity cooling system. In embodiments which provide cooling to a plurality of stationary exercise devices from a common source of cooling air, regulation can be included so as to provide a desired pressure and flow of cooling air to each of the stationary exercise devices, regardless of how much cooling air is flowing to the other stationary exercise devices, as will be understood by those skilled in the art. 
         [0164]    Other modifications and implementations will occur to those skilled in the art without departing from the spirit and the scope of the invention as claimed. Accordingly, the above description is not intended to limit the invention, except as indicated in the following claims.
