FIELD OF THE INVENTION
The present invention generally relates to device is for immediate evacuation when a person is injured, or passively resistant whether conscious or unconscious for use in the field of transferring a person that needs extracting from a first location to another location in response to emergency situations.
BACKGROUND
Persons of limited mobility, such as paraplegics, quadriplegics, and those suffering from diseases or conditions such as muscular dystrophy, multiple sclerosis, ALS, and cerebral palsy, typically encounter difficulties when faced with a situation where they must be transferred from one location to another, such as from a wheelchair seat to an airfronte seat, a car seat, or a recreational seat (e.g., a kayak or sit ski seat). Additionally, in emergency evacuation situations, it can be difficult to evacuate wheelchair-bound or injured persons from any multi-story building, particularly from skyscrapers or other buildings requiring evacuation down multiple flights of stairs or if in the interests of security, a person needed to be rapidly immobilized and evacuated from an unsecured location to a remote location.
Transfer devices for extracting and transporting such persons from one location to another and emergency evacuation devices currently exist. These transfer devices are typically mechanical lifts and/or slings that require trained operators and heavy mechanical equipment to use. Similarly, such emergency evacuation devices are typically heavy, rigid devices that are difficult to use in emergency situations, particularly by untrained personnel. They are rarely available when needed due to their size and the difficulty in storing such devices. These transfer and emergency evacuation devices also fail to adequately secure the person being transported in the device. Thus, there is a need in the art for a person transfer, immobilizer, and carrier device that is lightweight can be used by unskilled operators or by people who work in public safety such as: police; fireman; tactical; homeland security; EMS units; Military personnel; Private Security Contractors or anyone with the need to easily and quickly lift, move, immobilize, and transport a person whom has fallen, conscious on unconscious, wounded in the line of fire, for a quick evacuation to get someone to safety.
There is a further need in the art for a person lifter and carrier that maintains the person being transported in a stable and immobilized position during use.
While multiple embodiments are disclosed, still other embodiments of the present invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a handheld sling for the purpose of extracting people from a first location or situation and then lifting people to transport from the first to a second location. The sling provides a safe, quick means of extracting people to safety or assisting in lifting a person. The first situation may be any emergency situation or other situation that requires rapid extraction or removal of people such as civilly disobedient protestors from a first location to a second location.
The handheld sling is a compact device that can be stored in a small carry case or may be disposed in a convenient location of a lifting person's body, wherein a lifting person is any person desiring to use the handheld sling to lift another person disposed or retained within the sling. While a lifting person may be any interested individual, the sling may prove particularly useful to law enforcement officials such as members of the police or SWAT teams. A law enforcement official may transport the handheld sling within an associated leg pouch for instant access to the sling when needed. Additionally, the sling is light-weight, durable and compact thereby allowing for stowage and retrieval to and from small spaces such as in the pocket of a pair of pants such as cargo pants, in the back of a wheelchair, or in a glove box. Existing related devices are cumbersome and not small enough to be able to carry and have in time of emergencies.
Several embodiments of a person extractor, transfer, immobilizer, and carrier sling are provided herein.
The sling is simplistic enough to be used by anyone and can be used for various uses. For the home, lifting an elderly or handicapped person or for tactical uses for SWAT, police or homeland security.
In one embodiment, the sling is used to transport the person from a wheelchair to a travel seat (e.g., an airfronte seat, a bus seat, or a car seat), or from the travel seat to a wheelchair. In one embodiment, the sling is used to transport the person from a recumbent or other position. For example, the sling can be used to transport the person from a seated or reclining position on the floor, ground, bed, recliner, or any other location. In an alternative embodiment, the sling can be used to transport the person in an emergency evacuation situation from a building. In yet another alternative embodiment, the sling is used to transport the person down a flight or a number of flights of stairs. In one embodiment, the sling is used to transport the person in an emergency rescue situation such as a hurricane, tornado, or flood. In one embodiment, the sling is used in conjunction with other ropes, cables, carabiners, and other safety equipment to lift and transport the person.
The sling may be particularly useful for any first responder such as Police, Fireman, Emergency Medical Service personnel, but may also be used in hospitals, airports, assisted Living Homes, or for personal use in the home. In yet another alternative embodiment, the sling is used to transport a person to a kayak, sit ski, or other recreational seat. The sling can be used to transport a person with physical disabilities, an injured person, an elderly person, or any other person who requires assistance or immobilizing.
In an embodiment of the invention, the sling for extracting and transporting people includes:
a plurality of lateral support straps;
at least two elongated longitudinal support straps interconnected with the plurality of lateral support straps to support a thigh region, a buttocks region, and a back region and optionally, at least one of a shoulder, a head, or a leg region of a lifted person disposed within the sling to facilitate secure transfer of the lifted person disposed within the sling from a first location to a desired second location, wherein the sling supports a lifted person disposed within the sling in either a seated or a reclined position while being lifted by at least two lifting persons, wherein the lifting persons are positioned along respective opposing sides of the lifted person disposed within the sling.
In an embodiment of the invention, each of the elongated longitudinal support straps are integrally formed with lateral support straps associated with a plurality of regions adapted to support a desired portion of a person's body including at least two buttocks lateral support straps and at least one lower back lateral support strap.
FIGS. 1-13 illustrate various embodiments of the person extractor, transfer, immobilizer, and carrier sling, hereinafter “sling” 30a-30f that support and immobilize selected regions of a lifted person's body. As used herein the term extract or variations thereof means to capture and remove a lifted person from a first location by enveloping the sling about the lifted person and disposing the lifted person within the sling. As used herein, the term immobilize means to limit or restrict the movement of selected regions of the lifted person or the entire body of the lifted person.
As shown in respective embodiments in FIGS. 1-2, 3, 4, 5-10, 11, and 12-13, the sling (30a-30f) supports the lifted person 206 in a seated (FIGS. 1-11) or in reclined position (FIGS. 12-13), while lifted by at least two lifting persons 208.
In the illustrated respective embodiments shown in FIG. 6, the lifting persons 208 are positioned on two opposing sides of the lifted person, but in other embodiments, the lifting persons 208 may be positioned in different locations along at least two opposing sides or along multiple sides of the lifted person (as shown in FIG. 13). In the embodiment shown in FIG. 6, the lifting persons 208 each grasp two associated loops along a same respective opposing side of the lifted person. However, it is contemplated that the same two lifting persons may be oriented about the lifted person such that loops on each opposing side of the lifted person may be grasped by each lifting person. In a non-limiting example, one lifting person may be positioned behind the lifted person to grasp two upper loops and the other lifting person may be positioned in front of the lifted person to grasp two lower loops.
A lifted person 206 is securely disposed or retained within and is supported by the sling. As used herein the terms disposed or retained are used interchangeably to describe a lifted person 206 that is positioned within the sling to be lifted by a lifting person 208 (shown in FIGS. 8, 13). The lifted person 206 (as shown in FIG. 2) has a torso 210 including an upper shoulder region 212, a back region 98, a thigh region 214, and a head region 203.
FIG. 1 is a front view of the sling 30a including a thigh support region having a thigh lifting strap 38a, a buttocks support region 34a, and a back support region 36a including a lateral back support strap 130a that attaches to the thigh lifting strap 38a, wherein the sling 30a is shown in an open position thereby allowing the details of the sling to be more easily seen.
FIG. 2 is a rear in-use view of the sling shown in FIG. 1 with a lifted person 206 positioned in a personal transfer and carrier sling 38a in accordance with one embodiment of the invention.
FIG. 3 illustrates a front view of a sling 30b similar to the sling 30a having a lateral back support strap 130b that attaches to a thigh support region 32b in two different locations along a thigh lifting strap 38b than the lateral back support strap 130a of sling 30a attaches to thigh lifting strap 38a. 
As shown in FIGS. 4, and 5-10, the slings 30c (FIG. 4) and 30d (FIGS. 5-10) each further include a shoulder support region extending upwardly from the back support region.
As shown in FIG. 11, a sling 30e includes a pair of elongated strap loops extending upwardly from a shoulder support region.
As shown in FIGS. 12-13, the sling 30f further includes a head support region and a leg support region including a hand grip region.
Each of the support regions forming each of the slings 30a-30f are formed by interconnected straps that may be of the same or varying widths and may have an associated indicating means such as color or indicia to facilitate use and orientation of each sling in lifting a lifted person 206.
In embodiments of the invention illustrated in FIGS. 1-13, an associated strap forming a respective thigh lifting strap for the thigh support region has a different width and a different color or indicia from each of the straps forming other regions including leg, buttocks, back, shoulder, and head support regions so that the respective thigh support region may be properly oriented to contact the lifted person's thigh region 214. The colors or indicia may vary in accordance with the desired purpose of the lifting persons 208.
In an embodiment of the invention, when each of the slings is used by first responders to an accident scene, the thigh lifting strap may be black and the plurality of straps forming one or more of the leg, buttocks, back, shoulder or head support regions may be orange so that the contrast between the thigh support region and the other regions is immediately apparent.
In another embodiment of the invention, where the sling is used by law enforcement officials to immobilize a person of interest, the coloring of the materials of the sling may be neutral to blend in with a surrounding environment so as to not draw attention to the sling before using the sling to immobilize the person of interest.
The sling may be formed by attaching interconnecting straps via any suitable means of attachment to secure a lifted person 206 therewithin. In an embodiment of the invention, the sling including interconnecting straps may be formed from a solid, continuous, patterned sheet of material that may be cut or stamped out in accordance with a predefined pattern to form integrally formed interconnecting straps.
In several embodiments of the invention shown in FIGS. 1-13, open regions are interposed between each of the straps bounded by a plurality of flexible strap grid patterns defined by each respective leg, thigh, buttocks, back, shoulder, and support region. The open regions in combination with the flexible grid patterns facilitate positioning of the sling around the person and facilitate removal of the sling.
In an embodiment of the invention, the sling may be formed by attaching interconnecting support straps including longitudinal and lateral support straps via any suitable permanent means of attachment thereby integrally forming each of the longitudinal support straps to a respective end of at least one lateral support strap, to an intermediary portion of at least one lateral support strap or to an intermediary portion of a thigh lifting strap.
In an embodiment of the invention, reinforcement of the intersection points may be made by a repetitive stitching pattern such as a box stitch on the overlapping sections, shown in more detail for each FIGS. 1-13, wherein each lateral support strap has two box stitch sections formed at either selected intermediary portions of the respective lateral support strap or at each lateral strap outer end. As shown in FIGS. 1-13 and each embodiment disclosed herein, each respective overlapping sections are reinforced by a box stitch. However, any suitable permanent means of attachment may be used to securely bind and therefore reinforce attachment of overlapping layers of strapping material.
A suitable permanent means of attachment or the process of attaching layers of strapping material as defined herein may include, but is not limited to sewing, rivets, adhesives, clasps, cord, choke holders, pins or any other known means of attaching two or more layers of strapping materials together. Each sling has straps stabilized together at a respective overlapping intersection points to provide structural support and integrity against exterior forces to securely bind the strapping material layers together and to hold the layers together so that the layers form a secure bond while under a predefined weight load.
In an embodiment of the invention, the sling supports a predefined weight load of at least a 400 pound person. In another embodiment the thigh support region has an associated thigh lifting strap that has a tensile strength of 2,030 pounds and additional support straps associated with the leg, buttocks, back, shoulder, and head regions have a tensile strength of 1,180 pounds.
In one embodiment of the invention, all strapping material including, but not limited to straps, strands, and webs used to form the body of the sling may be made from a flexible and durable support material that is resistant to heat and UV radiation as well as snags, wrinkles, and twists. In another embodiment of the invention, the strapping material may be washable in a bleach solution as to a solution of 10 to one from any biohazard material (such as blood).
In one embodiment of the invention, the strapping material may include a treated nylon webbing material, polypropylene fibers or canvas.
In one embodiment, each of the sling straps are made from the same material as the thigh lifting strap. In one embodiment of the invention, the thigh lifting strap has a width dimension that is wider than a dimension of each of the straps forming the buttocks, back, and optionally, at least one of the shoulder, head and leg support regions. In an embodiment of the invention, the thigh lifting strap has a width dimension of three inches and all other sling support straps have a width dimensions of two inches. However, in another embodiment of the invention, the thigh lifting strap and all other support straps forming the sling have equal widths.
The sling does not require the use of fasteners to secure the straps to a person disposed within the sling as the structure of the sling when assembled and used by a person being carried, defined herein as a “lifted person 206”, allows for secure engagement of the lifted person's body being lifted or carried by a “lifting person 208”.
Additionally, invasive touching of the lifted person 206 disposed within the sling is unnecessary as the lifted person 206 is fully enveloped and immobilized within the sling and thus, there is no need for further direct contact of the lifted person's body.
In one embodiment, the sling includes a plurality of support straps that reinforces selected regions of or all of the sling and further includes loops forming handles or hand grips for grasping by a lifting person's hand. The handles or hand grips are sized to allow a lifting person 208 to fit all or a portion of the lifting person's hand 207 through the loop. The loops allow a lifting person to fit all or a portion of the lifting person's hand through the thigh lifting handle thereby allowing lifting of the lifted person without invasive touching of the lifted person.
In other embodiments, the support straps and loops are formed from any material that may adequately support the weight of the person being lifted without breaking or compromising the structure or integrity of any portion of the sling.
Additionally, each sling structure also allows the lifted person 206 to wear or be disposed within the sling while in either a reclined or a seated position with a reduced risk of injury.
As used herein, like elements will be referred to with like reference numbers throughout. The various embodiments of the sling 30a-30e have similarly referenced elements having same reference number prefix but include different suffices “a”-“e” to respectively associate like elements of different embodiments having a similar function with an embodiment with the same suffix. For example the thigh lifting strap 38a shown in FIGS. 1-2 associated with sling 30a performs essentially the same function as thigh lifting straps with the same prefix “38”, i.e. 38b-38f associated with slings 30b-f shown in FIGS. 3 (38b having same suffix “b” as sling 30b), 4 (38c having same suffix “c” as sling 30c), 5-10 (38d having same suffix “d” as sling 30d), 11 (38e having same suffix “e” as sling 30e), and 12-13 (38f having same suffix “f” as sling 30f), respectively.

In several embodiments of the invention methods of lifting the person in the slings 30a-e prove useful in situations when law enforcement officials have persons of interest that they desire to rapidly extract, immobilize and transport to another location. Protesters whom are positioned in a seated or reclined position on the ground. The slings allow the law enforcement official an option that does not require dragging the lifted person 206 but instead provides a method wherein the law enforcement official tilt the lifted person 206 to a first side, places the thigh lifting strap under a second side of the lifted person 206, tilts the lifted person 206 to the second side to ensure that the thigh lifting strap is under the buttocks region. The thigh and buttocks support regions are slipped under the lifted person 206 such that the thigh lifting strap extends upwardly on both sides of the lifted person 206 with the first and second thigh loops available for grasping on each side of the person. Once the immobilized person is properly positioned within the sling the law enforcement official may gently lift the lifted person 206 to securely transport the lifted person 206 to a desired location. If the use of the sling prevents hostile movements attempt while the lifted person 206 is picked up as opposed to being grabbed by their arm pits without use of the sling.
In certain situations the slings 30c, 30d and 30e (shown in FIGS. 4-11) may be used in handcuff situations, as shown for example in particular with reference to FIGS. 9-10. The opening bounded by lateral straps on the lower sling structure are positioned to allow an immobilized handcuffed lifted person, having hands disposed behind the lifted person's back to have the lifted person's hands comfortably disposed through an opening and secured between the lateral straps defining the back support and the buttocks support regions, wherein the weight of the lifted person 206 secured within the opening assists in applying pressure to the handcuffed hand region of the lifted person to further secure the immobilization of the handcuffed person. The handcuffed lifted person may need to be restrained with force or may be compliant such as a participant in a civil disorder or disobedience situation.
An advantage of the loop handles used by the lifting persons 208 provides a respective loop to be grasped in addition to grasping of a respective strap. The weight of the immobilized person on the lifting person's 208 wrist and hand is transferred to the forearms of the lifting person 208 thus allowing for a more comfortable and stronger grip, for easier carrying, and for less strain and fatigue on the lifting person's 208 arm hands, fingers and back. The weight shifting properties of the sling in-use allows transport of the lifted person 206 to be performed more comfortably and for further distances than in slings that do not provide such weight transfer properties. The sling provides a unique support structure of interconnecting straps that allows lifting persons 208 to lift a lifted person 206 without injuring either the lifted or lifting person 208 or persons. The unique design allows for a comfortable transport for a further distance and for lifting people who perform such lifting activities on a repetitive basis.
Another embodiment encompasses a possible law enforcement situation which includes the placement of the lower grid strapping in the back of the unit that allows a law enforcement official to place a person of interest in the sling either while their hands are behind their back in handcuffs or to immobilize the position the hands of person of interest to be initially placed within an associated sling opening and then handcuffed. The placing of the back support lateral strap allows the back support strap to support the lifted persons 206 hands or arms making wearing the sling comfortable and non-invasive.
Another method of using the sling to lift a person includes positioning the back support region adjacent to the back region of the person; positioning and pulling the thigh lifting strap under the thigh region 214; and lifting the lifted person 206 using the sling by applying an upward force to the back support region and to selected portions of the thigh lifting strap that and grasped by the lifting person 208. The method may be used to lift people disposed within any of slings 30a-30f. With regard to lifting persons using the sling 39f, the same method may be used and in addition, once the lifted person is disposed within the sling, the lifted person may recline thereby having both the lifted person's head and leg regions supported by the sling.
In an embodiment of the invention shown in FIG. 8, only two lifting persons 208 are required for transfer. In other embodiments of the invention, anywhere from two people to seven people (as shown in FIG. 13) necessary to extract, transfer, immobilize, and carry a lifted person 206.
The lifting persons 208 do not require special skills or training to use the sling. In several embodiments of the invention, the lifting persons 208 may be located behind the lifted person's 206 back and in front of the person's thigh region 214, or alternatively may be located on either side of the lifted person.
In one embodiment, the lifting persons 208 are located on opposing sides of the person as shown in more detail in FIG. 8. Thus, each lifting person 208 uses a respective one shoulder strap, and a respective thigh loop associated with a same respective side of the lifted person 206 opposing the side of the lifted person where the other lifting person is positioned to lift the lifted person 206.
In another embodiment, one of the lifting persons 208 is positioned respectively behind at the lifting person's 208 back region and grasps the associated shoulder strap loops and another lifting person 208 is located in front of the lifting person's 208 thigh region 214, and grasps each of the thigh loops to lift a lifted person 206. In other embodiments, the lifting persons 208 may be otherwise positioned around the lifted person 206 as necessitated by a particular situation and may use any combination of the loop handles to lift the person accordingly.
While the invention is amenable to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are described in detail below.
