TECHNICAL FIELD
This invention relates to the field of portable shelters, shelter systems, and methods of portable shelter deployment. Specifically, this invention relates to temporary housing shelters which may be deployed in emergency housing situations.
BACKGROUND
Until now, humanitarian aid organizations, disaster relief agencies, and most governments were missing a critical tool for emergency recover efforts-readily deployable housing for displaced individuals and families. After most natural and man-made disasters, housing needs can be broken into three main periods: short-term housing, medium-term housing, and long-term housing. A few types of specific disasters can be forecast, such as hurricanes, which create a different housing need and a fourth period: pre-event sheltering. The general housing needs during and between those periods are drastically different. Currently, there are no emergency housing systems that can address all four periods and yet be flexible enough to transition from one housing period to the next as needs change, creating a housing gap that exacerbates recovery efforts and increases victims' misery.
For example, when Hurricane Katrina struck Louisiana and Mississippi coastal regions of the United States in August 2005, many residents of those states were left with houses submerged under water or without homes or shelter of any type. After residents in more northern parts of Mississippi were having power returned to their homes, many on the Mississippi Gulf Coast were still living in tents in the parking lots of destroyed retail stores. In Louisiana, many houses also were destroyed in the southeastern parishes, and many New Orleans residents, who were unable to evacuate before the storm, were stranded at the Louisiana Superdome or New Orleans Convention Center in detestable conditions.
After Hurricane Katrina, one government agency attempted to provide housing assistance in the form of trailers, housing vouchers, leased cruise ship cabins, etc. to those most affected by the storm. However, each of these systems has major drawbacks.
Specifically, regarding the housing vouchers, they proved to be inadequate at sheltering large populations for several obvious reasons. First, a housing voucher requires an individual or a family to be relocated to other areas of the affected region in order to shelter them in existing housing units. During a large displacement of the population due to a disaster such as Hurricane Katrina, regional housing quickly reaches capacity, so the remainder of the displaced population is moved out of the region. In the case of Katrina, families from New Orleans were relocated as far away as Boston and Phoenix. By redistributing a large number of people in such an abrupt and rapid manner, regional infrastructure is overwhelmed and cannot maintain day-to-day operations. Housing vouchers present numerous problems with fraud, abuse, and the cost of living in the varying locations to which families are displaced.
Cruise ships were leased after Katrina for a relatively high nightly cost on a per person basis and for a maximum stay of six months. While these ships do allow a number of people to stay in a compact, self-sufficient area for an extended time period, the cruise ships are limited to deep-water ports for deployment, can only handle a small amount of the population from a major disaster, and must be leased or rented from private or foreign fleets.
One governmental agency was widely criticized for the slow and inadequate response in providing temporary housing to residents in need in Mississippi and Louisiana and for the high cost of the travel-type trailers provided to residents. The subject trailers cost approximately $65,000.00 each for purchase and setup on site. This price did not include transportation costs of each trailer to the deployment site or the removal costs of each trailer once it is no longer needed. Also, the trailers are not designed for long-term storage and are too bulky to efficiently store in large numbers. Moreover, the trailers were of the type that one truck could only pull one trailer, which resulted in the trailers being individually delivered to individuals and families in Mississippi and Louisiana using individual pickup trucks, which resulted in slow deployment of these trailers to those residents in need of temporary housing.
Therefore, it is clear that past solutions have many flaws without even taking into consideration the sheer costs associated with each. As such, there exists a need for housing for similarly displaced individuals and families.
SUMMARY OF THE INVENTION
The present invention meets this need by providing, amongst other things, portable shelters which can be deployed individually or as part of a larger system of shelter. The present invention also provides a facile method of deploying portable shelters to meet these housing needs.
The present invention provides a better solution to the housing gap—comprehensive, rapid-deploy shelters and shelter systems with a variety of customizable configurations to meet any challenge related to the actual disaster or deployment site. The systems of the present invention comprise shelter units, accessories, and supporting infrastructure that can be easily transported on a rapid timeframe. The systems' deployment sites can keep displaced populations as close to their homes as safely possible. The individual shelter units of the systems of the present invention provide safe, private sleeping arrangements for individuals and families. Each unit could offer power and climate control and would offer security, durability, and expandability for longer-term deployments. System components can endure long-term storage in warehouse-type environments, be rapidly transported through conventional means, and be fully deployable in large numbers in less than 24 hours. Also, the financial impact of a large-scale disaster can be somewhat tapered by creating a complete system for the very purpose of emergency housing that is easily transportable, reusable, and maintainable.
This emergency housing system is designed to be as flexible as possible in terms of deployment. This flexibility allows the system to address almost any mass housing need that may arise from natural disasters to war refugees. Below are the two main types of deployment scenarios the system operates under, soft deployment and hard deployment. A soft deployment uses a host facility augmented only by the shelter units; whereas, a hard deployment essentially creates a self-sustaining community at virtually any location by deploying shelter units along with power generators, climate control equipment, sanitation facilities, and medical service facilities. These two main deployment scenarios may also be blended to provide a tailored solution to a specific circumstance. For example, a partial system may be deployed at a host facility. The host facility could provide central medical care, food services, and sanitation facilities while the emergency housing system provides the living/sleeping quarters, partial power, and climate control. There are many of options that exist between these two scenarios and this system can be tailored to fit any situation.
Specifically, two particular embodiments of the shelters of this invention, which are discussed in greater detail infra, are “soft-walled shelters” which each comprise rigid top and bottom frames and collapsible support arms connecting each rigid top frame its respective rigid bottom frame and “rigid shelters” which each comprise a hard shell member and a rigid floor member which are interlockable one to the other.
In a soft deployment, the shelter units are deployed at an existing facility that is designed to handle large crowds, such as a sports arena or a convention center. In this scenario, the shelter units provide living/sleeping quarters for people while the adjacent facility is used for power, sanitation facilities, and food services. This option allows an extremely rapid response to a disaster event since only the shelter units are deployed from the system and the existing host facility provides the additional support. Depending on the host facility and the type of disaster being addressed, it may make sense to deploy shelters inside that facility. In the soft deployment, either the soft-wall shelters or the rigid shelters or some combination thereof can be used. However, because the soft-wall shelter collapses into a small enough package for storage and transport that it will fit through most double doorways, the soft-wall shelter is preferable in soft deployment. This would allow a possible deployment site, such as the Astrodome in Houston, Tex., to shield shelters from extreme weather conditions while directly powering and providing its own climate control systems to heat or cool the shelters.
In a hard deployment, the entire shelter system is deployed without the aid of an existing facility. In this scenario, the shelter units provide living/sleeping quarters but are augmented with other system components such as portable power generators, climate control equipment, and sanitation facilities. While this scenario would require more time to implement than a soft deployment, it could still be completed in a very rapid manner—only adding a few hours overall to the deployment timeframe. A hard deployment would allow aid and housing to be delivered wherever it is needed most, regardless of the conditions present there before, during, or after a disaster event. With the system in this configuration, a deployment site can be as diverse as a shopping center parking lot, an elevated roadway, a parking garage, a vacant lot, or simply an empty pasture. In the hard deployment, either the soft-wall shelters or the rigid shelters or some combination thereof can be used.
When not in use, both of the shelter concepts are able to nest with similar shelters and flat pack for storage and transport. They can be stored efficiently until they are needed due to their rugged, all weather design which allows them to endure very long term storage spans without decay or wear. All system components can be stored in centralized warehouse type facilities that could serve as distribution centers. These facilities would be located near major thoroughfares, rail lines, airports, or ports. These distribution centers may be stocked with certain system components to allow for a more appropriate response to the typical types of disasters in a particular region. System components can then be rapidly loaded and transported from these storage facilities to the predetermined deployment sites using various modes of transit that may be available at a given moment or location.
