INCORPORATION BY REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISCNot Applicable.
BACKGROUND OF THE INVENTIONA convenient, efficient means of transporting a load over a distance where no existing means of transport is available has many applications. Perhaps most notably, a device or system capable of such transport can be used to extract people from inaccessible locations, such as from a high-rise building. The 9/11 disaster affirmed the need for a device or system capable of extracting people from a building when those people are trapped by structural failure, fire, or other circumstances. The events of 9/11 also confirmed the need for a device or system for inserting rescue personnel into such a building. Though the 9/11 disaster is the most high-profile instance where a device or system in accordance with the present invention might have saved lives, such situations arise regularly. In San Juan, Puerto Rico, 86 lives were lost some years ago when the Dupont Plaza Hotel caught fire. In 1980, 85 people died when the MGM Grand Hotel in Las Vegas, Nev. burned. In the latter instance, lives were lost primarily due to poisonous gas and smoke rising through elevator shafts. Helicopters were used in both cases to lift people from rooftops, and a small number were saved using this method, but the availability of helicopters on alert and capable of lifting large numbers of people is small and, in some locales, may be non-existent. Additionally, the use of helicopters in the burning building environment presents an additional danger due to heat, smoke, and turbulence caused by fire and wind currents that normally exist around tall buildings.
In the case of the 9/11 disaster, elevators were unusable, leaving emergency stairwells or windows as the only means of escape from the building. Use of windows is unacceptable unless a fire truck ladder can reach the window in question, often not the case in extremely tall buildings. Stairwells are slow and firemen have to use the same stairs to reach the upper floors, leading to crowding in the stairwells such that firemen are hindering the movement of people down the stairwells and to the outside, and people fleeing the building hinder the movement of firemen up the stairway to fight the fire. Further, stairwells may not be an option for disabled persons, and moving injured people down a stairwell is difficult.
The need for a device or system of extracting people from buildings is not limited to a fire situation. Partial building collapse as a result of an earthquake or faulty construction can lead to a similar need. Partial collapse of a building causes survivors to be trapped on the upper floors where it is difficult and dangerous for them to attempt to extract themselves or for rescue personnel to reach them.
In addition to rescue scenarios, a need exists for an efficient, independent means of moving a load vertically or horizontally across a distance. For example, it is generally necessary to move loads across a distance during the construction of high-rise buildings, bridges, and the like.
In any of the scenarios above, it is desirable that the device or system of transport be truly independent in that it have its own power supply, means of locomotion, and the like. Such a device is also needed for transport of materials in space, or as a “space elevator.” Also needed is a means of moving a load along mine shafts or extracting persons therefrom. In addition to extraction, there is also a need for a system or device for placing persons at a location or allowing surveillance therefrom. These and other needs are met by the present invention, as will be detailed more fully below.
In addition, some proposed solutions to the problems associated with emergency situations such as in high rise buildings require bulky or undesirable equipment to be retained at the building site for use by fire, rescue, or other personnel during an emergency. Further, such equipment is required at every site for which a potential solution to the problem of emergencies is desired. There is, therefore, a need for a mobile device that can be retained by fire, rescue, or other emergency personnel and transported and used at any site where such a device becomes necessary. The present invention meets these needs as further described below.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides a device for moving a load across a distance. The device preferably includes a frame portion, a first wheel portion associated with the frame portion at a first position, a second wheel portion associated with the frame portion at a second position, and a bias restriction portion associated with the frame at a third position. The weight of a load associated with the frame portion biases the first and second wheels against a guide, the guide being disposed between the first and second wheels such that the first and second wheels engage the guide and secure the present device thereto. The bias restriction portion restricts the biasing of the first and second wheels to within predetermined limits.
In another aspect of the present invention the bias restricting portion is a bias restriction wheel.
In another aspect of the present invention the guide includes a first plurality of teeth disposed along a surface thereof, and furthermore at least one of the first and second wheels includes a second plurality of teeth disposed along a surface thereof, that first plurality of teeth and the second plurality of teeth being adapted to engage one another.
In still another aspect of the present invention, the guide includes a cutout portion for receiving at least one of the first and second wheels therein.
In another aspect of the present invention, the device includes a motor operably engaged with said device in order to move said device from a first location to a second location.
In another aspect of the present invention, the device includes a powered portion having a climbing portion associated therewith, and an insertion compartment adapted to be pulled by the powered portion.
In still another aspect of the present invention, the insertion compartment is adapted to receive the powered portion on an outer surface thereof such that the climbing mechanism associated with the powered portion can be used to move the insertion compartment along a guide.
In another aspect of the present invention, the device includes a staging portion fixedly attached to said frame, said staging portion adapted to contain at least one person and to allow ready entry into and exit from said device.
This application is a continuation-in-part of U.S. patent application Ser. No. 10/889,091, filed on Jul. 12, 2004, which Application in turn claimed benefit of U.S. Provisional Patent Application Ser. No. 60/486,048, filed on Jul. 10, 2003, and both documents are herein incorporated by reference in their entirety. In each of the embodiments of the invention described in those references, and in the embodiments of the present invention described herein, the underlying principle of the invention is the same. The present invention harnesses the force of gravity, normally a hinderance to the task of moving a load vertically or in any direction away from the earth's center of mass, and renders this force an asset. It is the force of gravity that serves to bias the wheels of the present device against a guide in such a way that the wheels are able to grip the guide and move the device therealong. In some embodiments of the present invention, the force of gravity is used to bias the wheels of the present device for horizontal movement rather than movement away from the earth's center of mass.
Turning now to the drawings, wherein like numerals indicate like parts,
In the embodiment of the present invention shown in
In each of the embodiments of the present invention described herein, the structure to which wheels 212, 214, 216, 318, and other analogous wheels or structures are attached, referred to as support portions, including crossbars, and the like, may be referred to collectively as frame portions, and the phrase “frame portion,” as used herein, includes any and all such structures described herein, and further is not limited by the structures described herein. A “frame portion” may be any suitable structure to which the necessary and/or desired functional components of the present invention are attached to form a climbing mechanism.
Each of the various wheels 512, 514, and 516 are preferably rotatably engaged with support portion 520. As in the embodiments of the present climbing mechanism described above, support portion 520 is engaged with a load that, through the force of gravity, biases climbing mechanism 510 such that first wheels 512 and second wheels 514 engage guide 522. First wheels 512 or second wheels 514 may be rotated, such as with a motor, allowing climbing mechanism 510 to move along the length of guide 522 in either direction depending on the direction of rotation of the wheels.
Also shown in
As described above, each of the various embodiments of the present climbing mechanism utilize the same underlying principle in order to move along a guide. As will be described now, the present climbing mechanism may be adapted for use with a mobile device that may be easily transported or driven to a site, such as a building, having a guide suitable for use by the present climbing mechanism. Thus, it is envisioned that numerous buildings and other structures in a given area may be fitted with a guide suitable for use by the present climbing mechanism. Local fire and rescue personnel, or other first responders, may then use mobile embodiments of the present invention in conjunction with these guides during an emergency situation or when otherwise necessary or desirable. The fire or rescue personnel, or other first responders, simply drive or transport the mobile embodiment of the present invention to the location having the guide and engage the climbing mechanism of the mobile device with the guide. The need for a built-in device or system of the present invention at each building or structure is eliminated (although it is contemplated that a device constructed in accordance with the teachings of the present invention certainly could be built in to a given structure). Various mobile embodiments of the present invention are now described, along with the various features and uses thereof.
Mobile framework 600, as shown in
Once powered portion 700 and insertion compartment 708 arrive at a location having a suitable guide (such as at a building fitted with guide 422), powered portion 700 engages the guide via the present climbing mechanism located within attachment portion 706. The climbing mechanism of the present invention is then used to move powered portion 700 vertically along the length of the guide over a distance adequate to allow insertion compartment 708 to be positioned beneath powered portion 700. The wheels of powered portion 700 are preferably retractable into the housing thereof, or are able to be received by an adequate structure atop insertion compartment 708. Once located under powered portion 700, insertion compartment 708 can be readily secured thereto. Then, as powered portion 700 is engaged to climb further along a length of the guide, insertion compartment 708 is moved along the guide as well, taking people or objects within to a desired location along the length of the guide.
Cockpit area 802 preferably includes all of the components a user of the present device would typically need to maneuver the device in order to transport it from one location to another. This generally includes a windshield such as windshield 814 so that a user of the present device is able to see the area immediately surrounding extraction device 800 and maneuver accordingly. Other items present within cockpit area 802 preferably include a seat, a steering apparatus, a safety harness or seatbelt for holding a user securely to the seat, pedals or other devices for acceleration, breaking, and if necessary, gear shifting. Various instruments indicating speed, remaining fuel, engine temperature, and the like are also contemplated. These aspects of the present invention are not specifically labeled or shown in the drawings as it is considered well within the scope of the art to incorporate these standard features into the novel device of the present invention. It is contemplated that any of the various embodiments of the device of the present invention can be fueled in any suitable manner, including but not limited to battery power, fuel cells, electric power, solar power, gasoline, diesel, propane, ethanol, and combinations thereof.
Body 804 of extraction device 800 preferably encloses the cockpit and other areas of the device such that the device becomes an enclosed vehicle during transport. Attachment portion 806 is preferably fixedly attached to body 804 and contains a climbing mechanism of the present invention such as climbing mechanism 410 or 510. When extraction device 800 arrives at a location having a suitable guide associated therewith, a user of extraction device 800 simply positions the device correctly relative to the guide (such as by using cutout portions in the guide, as described above), then engages the climbing mechanism within attachment portion 806 to the guide, and extraction device 800 moves along the length of the guide.
As also shown in
In any of the embodiments described herein, or in other embodiments of the present invention not described herein, any portion of the present device used to support or contain first responders or other personnel which the present device is active may be referred to generally as a “staging portion.” This includes the support platform, insertion compartment, and interior spaces of the present device described above.
Although the present description refers to a ‘climbing mechanism’ or ‘climbing portion’ of the present device relying on the biasing mechanism described above, it is contemplated that the climbing portion of the present device is able to move the present device in a horizontal as well as vertical manner, or along any incline therebetween. It is further understood that the present description refers to a frame associated with climbing portion (such as the crossbar and other structural features associated therewith, which may be referred to generally a frame), as well as a frame associated with the guide-free mobile aspects of the device described above. Likewise, some wheels described above are associated with the climbing portion while others are associated with the guide-free mobile aspects of the device. For the sake of clarity, these portions of the present invention may be referred to as the climbing frame and climbing wheels (when referring to those aspects of the invention associated with the climbing mechanism), and simply as the wheels and frame when referring to those aspects not directly associated with the climbing mechanism. Further, although various platforms, insertion compartments, or other features of the present invention are described above for housing rescue or other personnel, or for containing individuals extracted from a building, for the sake of simplicity these portions of the present invention may be referred to generally as staging portions.
In addition to the above, it is further contemplated that the climbing mechanism of the present device may, in some embodiments, include the ability to allow an operator of the present device to manually move the device along a guide in the event that a motorized aspect of the present device for moving the device along a guide should fail. Further, it is contemplated that any of the above embodiments of the present invention may be provided as permanent or removable portions of a structure, such that the equivalent of the mobile embodiments of the device described above may be located and positioned at a structure as a matter of course, rather than relying on transportation to a structure at the time of an emergency.
It is also contemplated that the present device may be built-in to a structure, such as a building, such that the climbing mechanism, guide, and other desired components of the present device, such as a staging portion, are permanent or semi-permanent components of a structure such as a building. In such embodiments, there is no need to transport the present device to a structure prior to using the present device.
The foregoing description of the various embodiments of the present invention is provided for purposes of clarity and illustration and is not intended to limit the present invention. It is contemplated that numerous modifications to the present invention will be readily apparent to those of skill in the art upon reading this disclosure. The foregoing should not be construed to limit the broad nature of the present invention, which is limited only by the claims that follow.
