DETAILED DESCRIPTION

(10) Aspects of the present invention and certain features, advantages, and details thereof, are explained more fully below with reference to the non-limiting examples illustrated in the accompanying drawings. Descriptions of well-known structures are omitted so as not to unnecessarily obscure the invention in detail. It should be understood, however, that the detailed description and the specific non-limiting examples, while indicating aspects of the invention, are given by way of illustration only, and are not by way of limitation. Various substitutions, modifications, additions, and/or arrangements, within the spirit and/or scope of the underlying inventive concepts will be apparent to those skilled in the art from this disclosure.

(11) As shown in FIGS. 1-3 the rescue hook, referred to generally by reference numeral 10, in one example, generally comprises a body 12 and a gate 14. The body 12 can comprise an upper portion 20, a middle portion 30, and a lower portion 40. According to one embodiment, the upper portion 20 can comprise an upper opening 22, the middle portion 30 can comprise a middle opening 32 and a gate attachment point 34, and the lower portion 40 can comprise a bend 42 and an arm 44, the arm 44 having an extended portion 45, dip 46, and barb 47. The lower and middle portions 30, 40 of the body 12 can form a throat 50 which the gate 14 can close.

(12) The rescue hook 10 can be attached to a placement tool that a user can use to move and position the rescue hook 10 onto an attachment point. Examples of placement tools include an extended stick, a hot stick, or a shotgun stick. A placement tool can have a universal adapter or be designed for use with an embodiment of the rescue hook 10. According to one embodiment, the placement tool can be connected to an attachment point on the upper portion 20. The attachment point can be the upper opening 22, or any other suitable means to be received or attached to the placement tool such as but not limited to a hook, magnet, or clip. According to an embodiment, the upper opening 22 is formed through the front and back surfaces of the upper portion 20. In the examples depicted the upper opening 22 is circular, however the upper opening 22 can be any other shape such as but not limited to oval, hexagonal, or elongated. In one embodiment, the upper opening 22 is positioned centrally along the horizontal axis of the rescue hook 10. In another embodiment, the upper opening 22 may be off set.

(13) The upper portion 20 can be dimensioned to receive or attach to a placement tool. For example, the specific shape of the upper portion 22 can be configured to be received by a placement tool. In FIGS. 1-3 the outer edges of the upper opening 22 are generally rectangular in shape with straight edges. Referring now to FIG. 4, according to one embodiment, the upper opening 22 is dimensioned to be large enough for the hook of the shotgun stick and the dimensions of the upper portion 20 are small enough to be accepted by the receiving end of a shotgun stick.

(14) The middle portion 30 of the body 12 is positioned below the upper portion 20 and can form the middle opening 32. The middle portion 30 according to one embodiment has a larger surface area than the upper portion 20. The body 12 is configured to facilitate the hook's 10 rotation into a position that captures the attachment point (hardware or webbing) and eliminate the risk of the attachment point releasing from the hook 10 prematurely. The middle opening 32 can be dimensioned to receive a connector such as a carabiner or clip and/or a rescue line or rope to the rescue hook 10. The middle opening 32 can be rounded such that a connector can glide around the edges easily. In the examples shown in the figures the middle opening 32 is circular, however the middle opening 32 can be any other shape such as but not limited to oval, hexagonal, or square. According to one embodiment the middle opening 32 is positioned centrally along a vertical axis of the rescue hook 10. This will facilitate the rescue hook 10 self-centering when there is a line or hook attached to the middle opening 32.

(15) In one example, the body 12 of the rescue hook 10 forms an acute angle between the middle portion 30 and lower portion 40. The space formed between arm 44, bend 42, and middle portion 30 of the body 12 is throat 50. Throat 50 has an open end and a closed end the closed end being enclosed with bend 42. The open end of throat 50 can be enclosed with gate 14. In one example the bend 42 is rounded to form an acute angle, in another example the bend 42 can have straight edges. The bend 42 can be off centered from the middle opening 32. In use, the hook 10 will self-center such that the attached load is positioned in the bend 42, away from the open end of throat 50 and gate 14.

(16) The dip 46 and barb 47 can be configured to guide the harness or strap of the attachment point into the throat 50. In one example, dip 46 and barb 47 extend past the middle portion 30 of the body 12. In the example shown in FIGS. 1-4 the barb 47 is rounded with the dip 46 adjacent to it. This embodiment has a rounded barb 47, but in another embodiment barb 47 can be ramped or alternatively shaped. In the embodiment shown dip 46 is a radius semi-circle that facilitates the hook 10 to catch an attachment point such as a harness and then slide into position. Radiused corners can prevent a sharp edge, the smoother the shape at the end the easier it is to slide into an attachment point.

(17) According to one embodiment, gate 14 encloses the open end of throat 50 and is positioned between the middle and lower portions 30 and 40 of the body 12. Gate 14 can pivot between a closed position and an open position. In one embodiment, one end of the gate 14 is pivotally attached to the gate attachment point 34 on the middle portion 30 of the body 12 such that it can pivot inward toward bend 42. Alternatively, gate 14 can be pivotably attached to the arm 44. The pivotal attachment can be accomplished by a spring or other mechanism, as should be known in the art, such that the gate 14 will close if no pressure is being applied to it. According to one embodiment, gate 14 can only pivot inward toward the bend 42. Once the load is past the gate 14, it cannot be slid back out without manual intervention. To remove the rescue hook 10 from the load a user will have to manually open the gate 14. In one embodiment, the gate 14 is a stainless-steel gate however, the gate can be made from any other suitable material. The length of gate 14 can be equal to or greater than the width of throat 50. In another embodiment, the rescue hook 10 does not have a gate 14.

(18) A benefit of rescue hook 10 over other rescue connectors is that in the situation of a wounded individual's sternal, dorsal or rescue connection point not being accessible to the individual performing the rescue. A user performing the rescue can attach the rescue hook 10 to the wounded individuals most accessible rated portion of their safety harness during the rescue process. The throat 50 is dimensioned to receive and hold multiple different sizes and shaped attachment points. Referring now to FIG. 4, according to one embodiment the rescue hook 10 can be used with webbing (ex. shoulder strap of a harness). The elongated throat 50 allows the wider width webbing to be slipped into the open end of the throat and held in the throat. Conventional hooks have smaller openings that are designed to be attached to hardware.

(19) FIGS. 5-7 illustrate the steps of the method of using the rescue hook 10. A user can attach a placement tool such as a shotgun stick to the upper portion 20 of the rescue hook 10 and attach a connector with a line to the middle opening 32. As seen in FIG. 5, using a placement tool, a user can position the rescue hook 10 onto any available attachment point on a load or a person who has been injured. The rescue hook 10 can have a line or hook attached to the middle opening 32. The rescue hook 10 can be attached to a clip, webbing, or other suitable rated attachment point. To attach the rescue hook 10, the user should guide the rated attachment point past the gate 14 to the bend 42 of the throat 50. Once the rescue hook 10 is attached the user can detach the placement tool or leave it in place. Detachment with a shotgun stick involves reverse pumping the shotgun stick.

(20) As shown in FIGS. 6 and 7, once the user begins to hoist the person upward with the line the rescue hook 10 will self-center. The line can rotate around the inner edge of the middle opening 32 such that the middle opening 32 is pointed toward the movement of the line and the rated attachment point of the load is in the bend 42 of the throat 50. This will put the weight of the load on the bottom of the rescue hook 10 in the bend 42. The weight should be pulling against the body 12 of the hook 10 and not pressing against gate 14. Once the load is in its desired place the user can remove the rescue hook 10 by opening the gate 14 and sliding the rated attachment point out of the throat 50 and past the open gate 14.

(21) The rescue hook 10 can be made of any suitable material such as but not limited to steel, aluminum, or titanium. In one example, the rescue hook 10 meets industry standards such as the ANSI Z359.12 standard.
