## Background
RELATED APPLICATION
This application is a nonprovisional of and claims the benefit of priority of U.S. Provisional Application 62/105,234, the entire contents of which are incorporated herein and made a part hereof by this reference.


FIELD OF THE INVENTION
This invention relates generally to regulation of a person's temperature, and, more particularly, to a mobile facility for heating, cooling and/or comforting a person.
BACKGROUND
Frequently, people attend events or visit attractions in hot and sunny or extremely cold weather. Many experience discomfort from the heat or cold, particularly when limited shade or shelter is available. Some suffer more severe consequences from the heat or cold, including dehydration, hyperthermia and heat stroke in the case of heat, hypothermia and frost bite in the case of cold. When a body absorbs more heat than it can dissipate, the result can be deadly, particularly for the elderly and infirm. Likewise, when the body's core temperature drops below that required for normal metabolism and body functions, severe injury may result.
What is needed is a mobile facility that can efficiently shade, cool or heat and hydrate streams of event attendees while providing comfortable seating and other conveniences. Not only would such a facility comfort attendees, but it would reduce risk of serious injury or death from excessive heating or freezing.
The invention is directed to overcoming one or more of the problems and solving one or more of the needs as set forth above.
SUMMARY OF THE INVENTION
To solve one or more of the problems set forth above, in an exemplary implementation of the invention, a mobile thermal regulation facility is a trailer mounted container suitable for temporary occupation by a plurality of individuals. The facility includes a plurality of walls a roof and a floor that define an interior space in which people may walk, stand and sit. The facility includes at least one door, preferably two or more doors for ingress and egress. Steps and/or ramps facilitate entering and exiting through the doors. An air conditioning unit, heater, heat pump, or refrigeration unit, or combinations of the foregoing, supply cooling and/or heating to the interior compartment of the facility. A dehumidifier may be provided to dehumidify the air. Various filters, ionizers and fragrance dispensers may be provided to filter, ionize or add a scent to the air. One or more fans and ductwork (e.g., ducts, vents, valves and other HVAC air distributions components) distribute cooled or heated air throughout the interior compartment. Windows admit natural light. Seating is provided. Thermal curtains may be draped at each door opening. Refreshment means (e.g., a water dispenser) may be provided. Electric and data utilities in the form of one or more outlets, USB charging stations, an internet access points (e.g., WiFi) may also be provided. Other accoutrements may include display screens for displaying television programming or video captured events.
In one embodiment, the facility includes an entrance and egress, each having a pair of spaced apart doors, an enclosed space between the doors, one door (the outside door) leading to outside (i.e., the ambient environment outside the facility) and the other door (the inside door) leading to the interior space of the facility. The door leading to the interior space swings inwardly into the facility to open, and the door leading to outside swings outwardly towards outside to open. An exhaust fan continuously or periodically exhausts air in the enclosed space to outside, to maintain a negative pressure in the enclosed space relative to the interior space of the facility and outside. The negative pressure keeps both doors in a closed sealed state until forcibly opened by a user. The doors are spaced apart sufficiently so that only one door may be opened at a time. Optionally, as and when the inside door is opened, the exhaust fan ceases operation, to minimize the draw of conditioned (heated or cooled) air from the interior space.

DETAILED DESCRIPTION
With reference to FIG. 1, a plan view conceptually illustrates an exemplary thermal regulation facility 100 according to principles of the invention. The facility 100 is a trailer mounted container suitable for temporary occupation by a plurality of individuals. The facility 100 includes a plurality of walls a roof and a floor that define an interior space in which people may walk, stand and sit.
The facility 100 includes at least one, preferably two doors 120, 125, each defining an entrance way and exit way, for ingress and egress. Steps 130, 135 and/or ramps facilitate entering and exiting through the doors 120, 125. In a preferred embodiment, the doors 120, 125 open outwardly and are located at opposite ends of the facility 100. However, the invention is not limited to a particular door configuration. In an embodiment with two doors 120, 125, each defining an entrance way and exit way, positioned at opposite ends of the facility, users may enter at one end and exit at the opposite end.
A trailer coupler 115 mounted to an A-frame 110 secures the trailer to the towing vehicle. The trailer includes wheels 140, 145 with axles. Depending upon the size of the trailer, more than one axle may be provided. In an alternative embodiment, the facility 100 may be an integral part of a vehicle, rather than a trailer that connects to a vehicle. In yet another alternative embodiment, the facility may comprise an equipped container (e.g., pod) that can be transported using a trailer or flatbed.
An air conditioning unit 105, heater, heat pump or refrigeration unit, or combinations of the foregoing, supply cooling and/or heating to the interior compartment of the facility 100. Such units are broadly referred to herein as thermal regulation or thermal conditioning units. One or more fans and ducts distribute cooled or heated air throughout the interior compartment. The temperature in the interior compartment may be regulated using a thermostat 226. A dehumidifier may be provided to dehumidify the air. Various filters, ionizers and fragrance dispensers may be provided to filter, ionize or add a scent to the air. One or more fans and ductwork 211 (e.g., ducts, vents, valves and other HVAC air distributions components) distribute cooled or heated air throughout the interior compartment.
In FIGS. 2 and 3, windows 150, 155 are shown. The windows 150, 155 admit natural light. The windows may be tinted or shaded to control the amount of light and heat admitted into the interior. In addition to windows for lighting, skylights and electric lighting, both interior and exterior lighting, may be provided.
Referring to the exemplary floor plan of the interior space in FIG. 4, an aisle 210 extends between opposed seats 200, 205 (e.g., bench seats on opposite sides of the aisle) from one door 120 (e.g., an entrance) to the other door 125 (e.g., an exit). Other seating and aisle arrangements are feasible within the scope and spirit of the invention.
To better insulate the interior space, thermal curtains 215, 220 may be draped at each door opening. The thermal curtain may comprise a plurality of flexible abutting or overlapping strips that may be pushed aside by entering or exiting patrons, but return to the abutting or overlapping arrangement to reduce flow into and out of the interior space when a door 120, 125 is opened.
To accommodate patrons, refreshment means 230 may be provided. For example, a water fountain 235, water cooler, coffee and/or hot chocolate dispenser, and/or one or more vending machines may be provided.
Additionally, electric and data utilities 225 in the form of one or more outlets, USB charging stations, an internet access points (e.g., WiFi) may be provided to accommodate patrons. Using the utilities, patrons may access the internet via WiFi and recharge electrical devices.
Other accoutrements provided in the interior space may include display screens for displaying television programming or video captured events, such as the event for which the patron is attending. Music may also be played in the interior space.
With reference now to FIG. 5, the facility may optionally include an entrance and egress 300, each having a pair of spaced apart doors 315, 320, an enclosed space 310 between the doors, one door (the outside door) 315 leading to outside (i.e., the ambient environment outside the facility) and the other door (the inside door) 320 leading to the interior space of the facility. Walls 305, with a floor and ceiling, or a similar structure substantially enclose the space 310. The door 320 leading to the interior space swings inwardly into the facility to open, and the door 315 leading to outside swings outwardly towards outside to open. An exhaust fan 330 continuously or periodically exhausts air in the enclosed space through a duct 335 to outside 340, to maintain a negative pressure in the enclosed space 310 relative to the interior space 345 of the facility and outside 340. The negative pressure keeps both doors in a closed sealed state, substantially flush against weatherstripping 316, 321 or similar insulating seals until forcibly opened by a user. The doors 315, 320 are spaced apart sufficiently so that only one door may be opened at a time. Optionally, as and when the inside door 320 is opened a switch 322 opens which causes the exhaust fan 330 to cease operation. The switch may be a plunger switch that remains closed when the door is closed and opens when the door is opened. When opened, the switch 322 directly or indirectly (e.g., via actuating or deactivating a solenoid) breaks the circuit supply electric power to the exhaust fan 330 or provides a sensible open door signal to a controller that regulates operation of the fan. Ceasing operating of the fan 330 minimizes the draw of conditioned (heated or cooled) air from the interior space into the space 310 between the doors 315, 320, when the interior door 320 is opened. As soon as the interior door closes, the exhaust fan resumes operation, maintaining a good seal between the interior space 345 of the facility and the ambient environment outside 340.
While an exemplary embodiment of the invention has been described, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum relationships for the components and steps of the invention, including variations in order, form, content, function and manner of operation, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. The above description and drawings are illustrative of modifications that can be made without departing from the present invention, the scope of which is to be limited only by the following claims. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents are intended to fall within the scope of the invention as claimed.
