Abstract
An apparatus and method for restraining a person's limbs are disclosed. The inventive apparatus includes at least one cuff module for application to the person's limbs. An optional interconnect may be provided for each set of cuff modules. Each cuff module includes a flat flexible elongated body with two rigid loops positioned apart from each other on its upper surface, a resilient lining positioned along a portion of the lower surface of the cuff body, the resilient lining being optionally removable, a flat rigid element attached to one end of the cuff body, and a releasable attachment device positioned on portions of the top and bottom surfaces of the cuff body. When the cuff module is applied to a limb, the cuff body is positioned around the limb such that the resilient lining wraps around the limb, and the rigid element is threaded initially through one rigid loop and then through the other rigid loop and pulled so that the body is tightened around the limb, and portions of the top and the bottom surfaces, on which the releasable attachment device is disposed, come into releasable attachment with one another to releasably secure the cuff module around the limb such that the cuff module cannot be unwrapped without first removing the rigid element from the second loop and then disengaging the releasable attachment device. An optional elastic band may be positioned on the top surface of the body to store a portion of the cuff body folded upon itself at least once when the cuff module is in a storage position.
Description




BACKGROUND OF THE INVENTION




The present invention is directed to a soft mechanical restraint system that may be easily and quickly deployed by a first person on a subject being held in a restrained position by a second person.




There are many thousands of human service and law enforcement agencies and facilities that provide care and supervision to aggressive, suicidal, and emotionally disturbed persons (hereinafter commonly referred to as “EDPs”). The staff and officers working in these agencies regularly come into physical contact with the EDPs through the use of physical subduing or restraint holds when the EDP becomes aggressive. Although there are many types of well-known physical subduing holds, the safest and most advantageous physical subduing hold is a Primary Restraint Technique (PRT) described in greater detail in a commonly assigned U.S. Pat. No. 6,273,091 entitled “APPARATUS AND METHOD FOR SAFELY MAINTAINING A RESTRAINING HOLD ON A PERSON”.




While restraint holds are useful for relatively short periods of time, often restraint of the EDP is necessary for an extended period. In such cases, the EDP must be restrained using some sort of a mechanical restraint system. Typically this involves placing wrist and ankle mechanical restraints on the EDP so that the EDP may be restrained for an extended period of time at the place of the restraint hold, or transported to another location while wearing the restraints. Most previously known restraint systems involve mechanical locks—for example, one popular restraint utilizes a mechanical spring-loaded lock that requires a special key to open. It takes at least 4-5 staff members to successfully apply such restraints at a speed of no lower than 2-3 minutes per restraint. During the application of these restraints, the EDP must be held down and poses a constant threat to the staff members until the restraining process is complete. Furthermore, removal of such restraints in emergency situations (i.e. in a medical emergency) takes a significant amount of time since a key must be located and used to open each restraint on each limb—this is especially problematic because without the key, which may not be immediately available in case of an emergency, the restraints cannot be removed at all. Finally, such complex restraint systems are expensive, heavy, and require extensive training to use properly.




Certain more recently developed restraints include mechanical locks based on a belt-like mechanism similar to a clothing belt with a buckle and a portion of the restraint having holes therein. Other similar restraints include a protruding metal member on one portion of the restraint and slots cut into the body of the restraint such that when the restraint is applied to the EDP, the portion with slots is pulled over the portion with the metal member until the restraint is tightened and the metal member is pushed through one of the slots. The end section of the slot portion may be further secured to the restraint. One of the main drawbacks with this arrangement is the fact that it is impossible to fit the restraint exactly to the hand or foot of the EDP since the restraint can only be tightened in increments equal to distance between the slots. As a result, it is possible that the restraint will be too loose (making it easier for the EDP to remove their limb from the restraint) or too tight (posing a danger of cutting off blood flow to the limb). Furthermore, a struggling unsupervised EDP may be able to loosen the restraint by pushing the slot portion of the restraint away from the metal member. Finally, all types of above restraints require special custom-made connectors to connect to one another or to stationary positions (i.e. a bed, etc.).




Thus, it would be desirable to provide an apparatus and method for quickly and easily applying mechanical restraints to a person being controlled through a restraining hold or who is otherwise immobile. It would furthermore be desirable to provide a mechanical restraint apparatus that is comfortable to the subject and that may be quickly and easily removed in case of an emergency. It would additionally be desirable to provide a mechanical restraint system that can provide a secure fit to limb of any size. It would further be desirable to provide a mechanical restraint system that can be attached to commonly available stationary connectors. It would also be desirable to provide a lightweight mechanical restraint system that is easy to transport and use, and that is inexpensive to manufacture.




SUMMARY OF THE INVENTION




The apparatus of the present invention and method of use thereof remedies the problems associated with applying mechanical restraints to violent and/or struggling EDPs (and with removing the restraints therefrom). In brief summary, the inventive soft circular restraints advantageously provide: (1) quick and easy application to the EDP without requiring mechanical locks or alignment of slots with metal members; (2) comfort to the EDP due to the soft constriction of the restraints; (3) quick and easy removal in case of an emergency; (4) a secure fit to any limb size as the inventive restraints are dynamically fitted exactly to the EDP limb size during application thereof; (5) easy attachment to commonly available stationary connectors, such as seat belt buckles; and (6) lightweight and simple construction, making the inventive restraints easy to transport and use and inexpensive to manufacture.




The inventive mechanical restraint apparatus consists of multiple cuff modules—two sized for arms and two sized for legs. Of course each cuff module may be utilized independently of one another. The arm cuff modules may be connected to one another by an interconnect, such as a piece of flexible but strong synthetic webbing (e.g. such as used in seat-belts) or a chain. Similarly, the leg cuff modules may also be interconnected in a similar manner. Optionally, each interconnect may be provided with a tensioning mechanism to control the interconnect length.




Each cuff module includes a flat flexible elongated body with two rigid loops positioned apart from each other on its upper surface, a resilient lining positioned along a portion of the lower surface of the body, the resilient lining being optionally removable, a flat rigid element attached to one end of the cuff body, and a releasable attachment device positioned on portions of the top and bottom surfaces of the cuff body. When the cuff module is applied to a limb, the cuff body is positioned around the limb such that the resilient lining wraps around the limb and the rigid element is threaded initially through one rigid loop and then through the other rigid loop and pulled, so that the cuff body is tightened around the limb, and portions of the top and the bottom surfaces, on which the releasable attachment device is disposed, come into releasable attachment with one another to releasably secure the cuff module around the limb, such that the cuff module cannot be unwrapped without first removing the rigid element from the second loop and then disengaging the releasable attachment device. An optional elastic band may be positioned on the top surface of the cuff body to store a portion of the cuff body folded upon itself at least once when the cuff module is in a storage position.




The inventive apparatus may be advantageously utilized once the EDP is restrained and placed into a controlled hold (or when the EDP is otherwise rendered immobile such as being asleep or unconscious). The cuff module is easily deployed from a storage position, by opening the cuff and pulling the rigid element which releases the folded portion of the cuff body from its folded position under the elastic band. Once the cuff module is placed around the EDP's wrist (or ankle), the rigid element is threaded through the first loop and then through the second loop in an intuitive circular motion. As the rigid element is pulled, the cuff module is tightened, and the releasable attachment device secures the cuff module in a closed position. The rigid element may then be attached to an optional external restraint device, such as a stationary bed connector or the like.




The inventive cuff module is easy to deploy because the staff member only has to pull on the rigid element to release the folded cuff body portion from its storage position, close the cuff module around the EDP's wrist (or ankle) and then just intuitively thread the rigid element through two loops in a circular motion around the cuff core—the releasable attachment device automatically secures the cuff module in the closed position. All together, the lightweight inventive cuff module can withstand approximately 10,000 pounds of force, all without any metal key elements.




Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention relates to an advantageous soft circular mechanical restraint apparatus and method that may be quickly and easily applied by a first person to a subject being held in a restraining hold by a second person, or to a subject who is otherwise immobilized (e.g. unconscious, sedated, asleep, etc.).




It should be understood that while the present invention refers to Emotionally Disturbed Persons (hereinafter “EDPs”) and Staff Members, the inventive techniques and apparatus may be applied in virtually any situation where a subject is being restrained and application of mechanical restraints is warranted. Thus, the present invention is applicable in law enforcement, hospitals, mental health care facilities, drug and alcohol rehabilitation centers, etc.




Before application of any sort of mechanical restraints, it is important that control over a struggling EDP is established by placing the EDP into a restraining hold. The Primary Restraint Technique (hereinafter “PRT”) is an advantageous modular single person restraint that is applied by an EDP care professional (hereinafter “staff member”) to an EDP from behind. The maneuvers involved in implementing the PRT are described in greater detail in Primary Restraint Technique (PRT) described in greater detail in a commonly assigned U.S. Pat. No. 6,273,091 entitled “APPARATUS AND METHOD FOR SAFELY MAINTAINING A RESTRAINING HOLD ON A PERSON” which is hereby incorporated by reference in its entirety. It should be noted, however, that the restraint system of the present invention does not require use of the PRT—it may be advantageously be utilized in any situation where the EDP is physically restrained by one or more staff members or other individuals. Of course, if the EDP is not ambulatory (i.e. unconscious or asleep) it is not necessary to apply any restraint holds before application of the inventive restraints.




In summary, the inventive mechanical restraint apparatus comprises a cuff module for each of the person's limbs. Preferably, two cuff modules sized for wrists and two cuff modules sized for ankles are provided, although a single size module may be readily utilized for both wrists and ankles for EDPs of certain sizes. Thus, it should be noted that while the exemplary inventive cuff modules are shown in the drawings and described below as being applied to wrists, the inventive cuff modules may be readily applied to ankles, as ankle cuff modules are identical to the wrist modules in all respects except optionally being larger sized. Optionally, each set of writs and ankle cuff modules may be color-coded for easy identification. For example, the wrist cuff modules may be blue while the ankle cuff modules may be red.




Of course, in accordance with the present invention, less than four cuff modules may be utilized depending on circumstances, without departing from the spirit of the invention. For example, in some cases only the wrist cuff modules may be applied to the EDP. The inventive cuff modules may also be provided with optional interconnects that connect each set of cuff modules to one another. Thus, the wrist cuff modules may be supplied with wrist interconnects, and the ankle cuff modules may be supplied with ankle interconnects.




Furthermore, while the various embodiments of the inventive apparatus are described with references to particular hook and loop material strips positioned on various portions of the inventive cuff module, any loop and hook material strips may be interchanged between one another throughout the cuff module as long as the interchange is consistent overall, as a matter of design choice.




Referring now to

FIG. 1A

, a first embodiment of a cuff module


10


is shown. The cuff module


10


includes an elongated cuff body


24


composed of a strong flexible material such as nylon webbing (for example, the webbing used in seat belts and parachute straps) with a top surface and a bottom surface, a first end and a second end. A rigid element


26


is connected to the second end of the cuff body


24


. The rigid element


26


is preferably composed of a hard material such as metal, hard plastic, or metal coated with a resilient material. The main purpose of the rigid element


26


is to allow the person applying the restraint to easily manipulate the second end of the cuff body


24


. Optionally, the rigid element


26


may be configured as a connector that may be connected to an external stationary restraint device (as described below in connection with

FIGS. 2C and 3

) or to a cuff module interconnect (as described below in connection with FIGS.


4


A and


4


B). For example, the rigid element


26


may be a male seat-belt type connector.




A first rigid loop


18


is positioned perpendicular to the top surface of the cuff body


24


, at a distance A away from the cuff body


24


first end. The rigid loop


18


is preferably generally rectangular and composed of a strong material such as metal, hard plastic, or metal coated with a resilient material. The opening in the rigid loop


18


is sized and configured to allow the rigid element


26


and a portion of the cuff body


24


to readily pass therethrough. Preferably, the rigid loop


18


has a limited range of pivoting motion about its lower portion by which it is attached to the cuff body


24


, however, the rigid loop


18


may also be secured in a non-movable or very limited pivot position perpendicular to the cuff body


24


. A second rigid loop


20


is positioned perpendicular to the top surface of the cuff body


24


a distance B away from the first rigid loop


18


, between the rigid loop


18


and the second end of the cuff body


24


. The rigid loop


20


is preferably identical to the rigid loop


18


, being generally rectangular and composed of a strong material such as metal, hard plastic, or metal coated with a resilient material. The opening in the rigid loop


20


is sized and configured to allow the rigid element


26


and a several folds of the cuff body


24


to readily pass therethrough. Preferably, the rigid loop


20


has a limited range of pivoting motion about its lower portion by which it is attached to the cuff body


24


, however, the rigid loop


20


may also be secured in a non-movable or very limited pivot position perpendicular to the cuff body


24


.




A first hook material strip


14


(such as hook Velcro®) is positioned on the top surface of the cuff body


24


between the rigid loop


18


and the first end of the cuff body


24


. Preferably, the hook material strip


14


fills a substantial portion of the area between the rigid loop


18


and the first end of the cuff body


24


. However, the hook material strip


14


can be smaller than that area or be composed from multiple hook material strips (not shown). A first loop material strip


16


(such as loop Velcro®) is positioned on the top surface of the cuff body


24


between the rigid loop


18


and the rigid loop


20


. Preferably, the loop material strip


16


fills a substantial portion of the area between the rigid loop


18


and the rigid loop


20


. However, the loop material strip


16


can be smaller than that area, or be composed from multiple loop material strips (not shown). An optional elastic band


22


is positioned at a distance C away from the rigid loop


20


, between the rigid loop


20


and the second end of the cuff body


24


. The elastic band


22


may be cloth-coated rubber, or any other strong and resilient elastic material. The elastic band


22


is used when the cuff module


10


is in a storage position, as described below in connection with FIG.


2


A.




An optional second hook material strip


12


(such as hook Velcro®) is positioned on the bottom surface of the cuff body


24


, the length of the second hook material strip


12


preferably being approximately equal to sum of distances A and B (and optionally equal to the sum of distances A, B and C). However, the length of the second hook material strip


12


can be smaller than that the sum of Distances A and B or be composed from multiple loop material strips (not shown) disposed along an area between the first end of the cuff body


24


and the elastic band


22


. The second hook material strip


12


is only necessary if the optional removable cuff liner


42


described below in connection with

FIG. 1E

is utilized. If the removable cuff liner


42


is not used, then the second hook material strip


12


is preferably replaced with a resilient (and optionally padded) material strip (not shown but having dimensions and position substantially similar to the second hook material strip


12


) for contacting the EDP's limb and for providing relative comfort to the EDP. Optionally the resilient material strip may be coated with, or comprise, a non-skid layer such as “shark-skin” rubber to provide a better grip on the EDP's limb and to prevent the cuff module


10


from freely rotating about the limb.




A third hook material strip


30


(such as hook Velcro®) is positioned on the bottom surface of the cuff body


24


, between the midpoint of a distance D and the second end of the cuff body


24


. The third hook material strip


30


is preferably equal to or smaller in size to the loop material strip


16


. The preferred position and size of the third hook material strip


30


is described below in connection with

FIGS. 2A

to


2


C. An optional fourth hook material strip


28


(such as hook Velcro®) is positioned on the bottom surface of the cuff body


24


, between the midpoint of a distance D and the elastic band


22


. The preferred position and size of the fourth hook material strip


28


is described below in connection with

FIGS. 2A

to


2


C. Optionally, either the entire area between the second hook strip


12


and the second end of the cuff body


24


, or a large portion thereof, may be covered with either a single elongated hook material strip (not shown) or provided with additional hook material strips (in addition to the strips


28


and


30


). The distance D is preferably greater than the sum of distances A, B and C.




In order to simplify fabrication of the cuff module


10


and to increase its strength, preferably, the cuff module body


24


is fabricated from a single long piece of webbing such that rigid loops


18


and


20


, the elastic band


22


and the rigid element


26


are connected to the cuff body


24


by having one or more portions of the cuff body


24


folded upon itself and attached (e.g. sewn) to itself to encompass portions of the rigid loops


18


and


20


, the elastic band


22


and the rigid element


26


. One folding configuration of the cuff body


24


is shown in

FIG. 1A

by way of example only. Other configurations and schemes of folding portions of the cuff body


24


upon itself to attach at least some of rigid loops


18


and


20


, the elastic band


22


and the rigid element


26


can be readily selected and implemented as a matter of design choice without departing from the spirit of the invention.




Referring now to

FIG. 1B

, a second embodiment of the cuff module


10


is shown as a cuff module


32


. The cuff module


32


is functionally identical in all respects to the cuff module


10


, except for the way the cuff module


32


is fabricated. The cuff module


32


comprises a cuff body


34


that is a simple elongated strip of a strong flexible material such as nylon webbing. However, instead of being attached by the cuff body


24


folded upon itself and attached to itself, the rigid loops


18


and


20


and the elastic band


22


are attached to the cuff body


36


by respective attachment devices


40


,


38


and


36


. The attachment devices


36


,


38


, and


40


may be small webbing strips sewn to the top surface of the cuff body


34


or other flexible attachment devices. In an alternate embodiment of the inventive cuff module (not shown) the cuff module


10


and cuff module


34


may be combined, where certain elements may be attached to a cuff body


24


or


34


by folding and attachment of the body to itself (as is done with the cuff module


10


) while other elements may be attached to the cuff body


24


or


34


via one or more attachment devices such as attachment devices


36


,


38


,


40


.




Referring now to

FIG. 1C

, a top view of the cuff module


10


is shown (the top view of the cuff module


34


of

FIG. 1B

looks identical). Referring now to

FIG. 2B

a bottom view of the cuff module


10


is shown (the bottom view of the cuff module


34


of

FIG. 1B

looks identical).




Referring now to

FIG. 1E

, the optional removable liner


42


is shown. The removable liner is disclosed in a previously filed commonly assigned co-pending U.S. Provisional Patent application entitled “Soft Circular Restraint with Removable Lining Apparatus and Method” from which the present application claims partial priority and which is hereby incorporated by reference in its entirety. The removable liner


42


comprises an upper layer


46


comprising a second loop material strip (such as loop Velcro®) preferably sized approximately equal to the second hook material strip


12


. However, the upper layer


46


may be slightly smaller or larger than the second hook material strip


12


as a matter of design choice. The removable liner


42


also comprises a lower layer


44


of substantially the same size as the upper layer


46


. The lower layer


44


is preferably a flexible resilient (and optionally padded) material strip for contacting the EDP's limb and for providing relative comfort to the EDP. Optionally, the lower layer


44


may be coated with, or comprise, a non-skid layer such as “shark-skin” rubber to provide a better grip on the EDP's limb and to prevent the cuff module


10


from freely rotating about the limb. Optionally, the lower layer


44


may be composed of an absorbent disposable material such as cotton and advantageously disposed after use, thus keeping the cuff module


10


clean and sterile.




The removable liner


42


also comprises a tab


48


for facilitating removal of the removable liner


42


from the cuff module


10


. Preferably, the tab


48


is positioned over one of the ends of the removable liner


42


and extending beyond the upper and lower layers


46


,


44


and composed of loop material (such as loop Velcro®). Optionally, the tab


48


may be composed of any other flexible material.




The removable liner


42


is removably attached to the second hook material strip


12


and positioned such that the end of the upper and lower layers


46


,


44


having the tab


48


attached thereto is aligned with an area under the elastic band


22


, and the tab


48


extends beyond the underside of the elastic band


22


toward the second end of the cuff body


24


.




While the above elements


12


,


14


,


16


,


28


,


30


,


42


and


48


are described with reference to either hook or loop material, it should be understood to one skilled in the art that any other flexible releasable attachment devices can be readily substituted for the hook and loop material without departing from the spirit of the invention. For example, two or more of the elements


12


,


14


,


16


,


28


,


30


,


42


and


48


may be replaced with releasable glue strips or the like. This arrangement may be particularly advantageous if the removable liner


42


is configured as a disposable liner.




Referring now to

FIGS. 2A

to


2


C, the operation of the cuff module


10


is shown as an exemplary application of the cuff module


10


to a wrist


100


. In

FIG. 2A

the cuff module


10


is shown in a storage position where a portion of the cuff body


24


is folded upon itself and stowed under the elastic band


22


(and optionally retained by the rigid loop


20


). Optionally, the rigid element


26


may also be stowed under the elastic band


22


but pointed away from the rigid loop


20


. Referring now to

FIG. 2B

, the cuff module


10


is applied to the wrist


100


by first wrapping the cuff body


24


around the wrist


100


as tightly as possible, such that the resilient liner lower surface


44


is in contact therewith, and such that the tab


48


is releasably attached to a portion of the first hook material strip


14


, thus at least temporarily securing the cuff module


10


around the wrist


100


. Then, the rigid element


26


is pulled away from the elastic band


22


causing the folded portion of the cuff body


24


to unfold. Referring now to

FIG. 2C

, the rigid element


26


is then first threaded through the loop


18


and then threaded through the loop


20


in an intuitive circular motion. As the rigid element


26


is tightly pulled, the third hook material strip


30


forms a releasable attachment connection with the first loop material strip


16


. Thus, the third hook material strip


30


should be sized, configured, and positioned along the bottom surface of the cuff body


24


in such a manner as to achieve contact with the first loop material strip


16


when the cuff module


10


is closed. Similarly, if the fourth hook material strip


28


is used, it forms a releasable attachment connection with the tab


48


. Thus, the fourth hook material strip


28


should be sized, configured, and positioned along the bottom surface of the cuff body


24


in such a manner as to achieve contact with the tab


48


when the cuff module


10


is closed. If the rigid element


26


is configured as a connector, then it may be releasably attached to an external stationary restraint


50


having a connector


52


for releasably connecting to the rigid element


26


, and a body


54


. Referring to

FIG. 3

, an isometric top view of the cuff module


10


applied to the wrist


100


is shown.




Once various above-described hook and loop material strips are attached to one another, they can only be pulled apart by applying a force substantially perpendicular thereto. As a result, due to the circular nature of the cuff module


10


and the fact that a portion of the cuff body


10


is treaded through and secured by the rigid loops


18


and


20


, it is impossible for the EDP to open the restraint on their own.




Advantageously, once the EDP is restrained and placed into a controlled hold (or when the EDP is otherwise disabled such as during sleep), the cuff module


10


may be easily deployed from the storage position and applied to the EDP by one person. The cuff module


10


is easy to deploy because the staff member only has to pull on the rigid element


26


to release the folded cuff body


24


portion from its storage position, close the cuff module


10


around the EDP's wrist (or ankle), and then just intuitively thread a portion of the cuff body


24


through two rigid loops


18


,


20


in a circular motion—the hook and loop strips on the cuff body


24


top and bottom surfaces automatically secure themselves to one another. All together, the lightweight inventive cuff module


10


can withstand approximately 10,000 pounds of force, all without any metal key elements.




It takes less than 25 seconds for a single person to deploy the inventive cuff module


10


from a storage position to the deployed restraint position. Because all elements of the inventive systems are flexible and soft, the EDP will not hurt themselves or experience significant discomfort by struggling against the restraints. Most importantly, the inventive cuff module


10


may be removed in one second in an emergency situation without need for a special key. Moreover, the cuff module
