[0048] The invention provides a rescue access bar and tools for forcible entry to a building together with other functions.

[0049] FIGS. 1-9 illustrate various aspects and features of an exemplary embodiment of rescue bar 10 as shown in FIGS. 1-5, including the pairings with a halligan bar 20 to form rescue access tool interlocks 100′, 100″, 100″′ and juxtaposition 100″″ depicted in FIGS. 6-9 respectively. Referring to FIGS. 1-3E, rescue bar 10 includes elongate handle 2 with a head end 6 at a first end of handle. In embodiments such as illustrated, head end 6 has a longitudinal central plane that bisects the head end 6. On one side of the plane bisecting head end 6 is a pair of jaw members 6A. On the other side of head end 6 is a blunt hook 6J including strike contact face 6I. A pair of aligned channels 6L disposed on opposed sides of a recessed bridge between the blunt hook 6J and the elongated handle 2, wherein the recessed bridge is disposed along the longitudinal plane of the elongated handle, wherein each of the pair of aligned channels 6L have an inner side wall and an outer side wall stepped up from opposing recessed planar surfaces of the recessed bridge, The recessed planar surfaces of aligned channels 6L merge to the open space and extend to the crown surface. As best illustrated in FIG. 4, various embodiments feature configuring aligned channels 6L such that a lower portion of its opposed inner side walls and outer side walls are disposed in opposed outward directions and an upper portion of its opposed inner side walls and outer side walls are disposed in opposed outward directions.

[0050] Referring to FIGS. 1-3E and 4 illustrating the configuration head end 6, blunt hook 6J is disposed on a substantially perpendicular axis of the longitudinal plane of head end 6. As shown, contact strike face 6I forms an outer surface of blunt hook 6J. An inner wall of blunt hook 6J defines open space 6K that extends along a main longitudinal plane aligned with handle 2 to merge with a channel 6L bridging blunt hook 6J and paired jaws 6A. Blunt hook 6J may include a tapered wedge that may be utilized to break apart or otherwise demolish construction materials such as for example, wood, metals, or other materials by striking blows upon the material.

[0051] Strike contact face 6I of blunt hook 6J has an outer surface configuring that can be used as striking tool, for example, to strike and thereby amplify force applied to a halligan bar. The force, concomitant with the weight of the rescue bar 10 facilitates expeditious opening of access doors and demolishing construction materials such as, for example, concrete, wood, metals. The amplified force is particularly useful for opening car doors and high security exterior doors and gates, or other materials. Strike contact face 6I may also be struck by a hammer or other striking tool in some applications.

[0052] As shown in FIGS. 1-3D and best illustrated in FIG. 4, strike contact face 6I includes a planar surface disposed in parallel alignment with the main longitudinal axis of the handle 2 and perpendicular to the longitudinal central plane of head end 6. As shown in the illustrated embodiment, an upper portion of strike contact face 6I is substantially parallel with the longitudinal of handle 2 while a lower portion of strike contact face 6I is disposed in a slightly offset angle directed inwardly toward handle 2. Now referring to FIGS. 3 and 3A, such offsetting of the lower portion of strike contact face 6I extends inwardly toward handle 2 disposes the lower portion of strike contact face in a continuous longitudinal plane with a portion of the back surface of upper crescent claw 4B on an opposing end of rescue bar 10. Such planar continuity of the lower portion of strike contact face 6I and the back surface of upper crescent claw 4B provides a spaced dual stable contact surface for placing rescue bar 10 on a resting surface. A further feature of blunt hook 6J includes rounding the corners of strike contact face 6I best illustrated in FIGS. 3C, 3E, 4 and 4B. The reduced contact with a surface enabled by the offset lower portion of strike contact face 6I and rounded corners lessens friction and thus eases movement such as sliding on a floor or tabletop to thereby help avoid scratching, abrading or otherwise damaging the surface contacted, especially when dropped or force is otherwise applied to the already heavy load of rescue bar 10. The lack of sharp corners of strike face 6I and overall smooth configuration of blunt end 6J further helps prevent catching and sticking to the materials being demolished thereby easing release of head end 6 following their penetration.

[0053] In the illustrated embodiment best shown in FIGS. 1 and 3, head end 6 includes a pair of jaws 6A consisting of upper jaw 6B and lower jaw 6C having opposed inner surfaces configuring gap 6D therebetween. In some embodiments, pair of jaws 6A may be utilized to grasp, manipulate, and/or otherwise demolish building materials such as, for example, lumber, bricks, drywall, concrete blocks and/or tile. Although shown in a fixed position, the upper and/or lower jaws may be adjustable in various alternative embodiments. As shown, an inner surface of lower jaw 6C has recessed teeth 6F. In alternative embodiments, pair of jaws 6A may include more or fewer teeth on upper jaw 6B and/or lower jaw 6C or no teeth at all.

[0054] Extended from upper jaw 6B of rescue bar 10 is a chisel end 6H, as illustrated in FIGS. 1-4. Chisel end 6H may be used to penetrate building materials such as wood (or other materials) for the purposes of demolition or for other purposes. In one embodiment, chisel end 6H may be positioned in a joint or gap, for example between a door and corresponding doorjamb, or other surface to be penetrated, and the strike contact face 6I may be struck by a hammer or other striking tool, to thereby drive wedge blade 6A is driven into gap or surface. An extended outer edge of chisel end 6H has a notched lock puller 6E shown best in FIG. 3E. In some embodiments, lock puller 6E may be beveled to facilitate insertion between a lock and door or door jamb. As with other features of rescue bar 10, lock puller 6E may provide further functionalities, including loosening fasteners and other hardware or structural impediments creating a barrier to access a jeopardized space.

[0055] Now referring to FIGS. 1-3 and 5, disposed along a coextensive longitudinal axis on an opposing end from head end 6 of the handle 2 is a sickle blade 4 including a lower claw 4A and upper crescent claw 4B integrally extending from a base portion joined to the elongated handle, wherein a substantially rounded inner periphery coextending from the upper crescent claw and the lower crescent claw configures a clearance space 4C therebetween. A width of upper claw 4B, lower claw 4A and rounded inner clearance space 4C are aligned along a common longitudinal plane with the elongated handle. Extending from inner clearance space 4C toward handle 2 and disposed in the base portion is a recessed portion having perpendicularly disposed side walls stepped up to opposed raised surfaces of lower claw 4A and upper crescent claw 4B joining opposed open ends of the recessed portion. Hence, the recessed portion disposed between opposed stepped side walls between lower claw 4A and the upper crescent claw 4B merges into the clearance space 4C.

[0056] In one embodiment, rescue bar 10 includes an aperture 4D. Aperture 4D hole extends completely through the width of sickle blade end 4. FIGS. 1-3 and 5 illustrate rescue access tool 10 having aperture 4D according to an embodiment. In some embodiments aperture 4D or other openings may be located in another element. A through hole such as aperture 4D may be drilled, punched or molded in various dimensions and configurations for multifarious uses, as detailed above. A particular efficacious utility of aperture 4D is for receiving a paired carabiner or other clasp or loop mechanism so as to attach a line or rope composed of a durable and strong textile such as nylon, metal wire rope or other suitable material.

[0057] An additional advantageous functionality of rescue bar 10 is provided by secure anchoring of blunt hook 6, or paired jaws 6B, 6C in or about material of a structure, for example by wedging against a gap, bar or plank, and then releasing and rappeling along the line attached to aperture 4D to safety. An escape route from an elevated level, for example through a window or from a rooftop or upper deck, may thus be accessed when other exits are blocked or unsafe. Alternatively, a rescue worker could also lower a person or pet affixed to the line to a lower level.

[0058] In preferred embodiments such as illustrated in FIGS. 1-9 and best shown in FIG. 2, rescue bar 10 is forged from a single piece of steel. Together with the durable, hardy and dense composition of the steel and lack of joints or welds, rescue bar 10 wields superior force to expedite rescue operations requiring latch disengagement and/or demolition for access. To ameliorate concomitant weight of such a heavy-duty construction, handle 2 may include one or more cavities 2A best shown in FIG. 1A. Additional cavities may be disposed along handle 2 to further reduce the mass and weight of rescue bar 2. Thus lightening the load typically increases speed and endurance and thereby enhances the performance of a fire fighter or other rescue worker.

[0059] In alternative embodiments the sides of handle 10 of rescue bar 10, as well as second handle 12 of halligan bar 20, may include one or more cavities. For example, they could include just one long cavity or multiple smaller cavities per side. In some embodiments, each may have differing numbers and patterns of recesses.

[0060] In various embodiments best illustrated in FIG. 2, rescue access tool 10 includes a grip cover 2C that may be attached to handle 2 by tightening screws 2C into corresponding threaded apertures disposed in steel handle bar 2B. Grip cover 2C may be composed of any skid resistant, and preferably resilient, material such as, for example, rubber, plastic, or other material on handle 2 and second handle 12 or other portions of rescue bar 10. The gripping material may be placed over or affixed to rescue access tool 10 to provide a more secure and comfortable grip for the rescue worker's hands. In some embodiments such as illustrated in FIGS. 1-9, protruding portions configured for seating within corresponding cavities may be included on an inner surface of the grip material. In addition to enhanced gripping, seated engagement of the protruding portions of the interior of grip cover 2C and corresponding cavities of steel handle bar 2B provide an esthetic and smooth surface for handle 2.

[0061] In the illustrated embodiments, rescue access tool 100′, 100″, 100″′ includes halligan bar 20 with adze pick end 14 and fork lever 16 disposed on opposed ends of second handle 12. As shown in FIGS. 6-9, halligan bar 20 includes handle 12 with a fork lever 16 and an adze pick end 14 disposed along a substantially longitudinal axis. Now referring to FIGS. 6, 7 and 8, fork lever 16 has a slot between tapered prongs that may be manipulated to remove fasteners such as, for example, nails, brads, staples, to enable demolishing or prying apart of materials. On an opposing end to fork lever 16 is Adze pick end 14 including Adze 14A and pick 14B. In the illustrated embodiment, adze 14A is bent in a direction that is offset from a perpendicular axis of handle 12 toward fork lever end 16 to facilitate prying and striking force. Pick 14B is circumferentially tapered and terminates in a pinnacle end to facilitate insertion within small joints or holes and may be used to penetrate multi-stepped and deeply creviced spaces in keyholes and latches to thereby breach an engaged lock.

[0062] FIGS. 6 and 8 illustrating the clasped interlock 100′ and a stepped interlock 100″ of the present invention show an aspect of adze 14A having a tapered blade bent inwardly from a perpendicular axis of handle 12. In the clasped interlock 100′, adze 14A may thus be used to pry material or remove a fastener on a flat work surface without head end 6 causing rescue bar 10 to prematurely bottom out.

[0063] In one embodiment best shown in FIG. 2, rescue bar 10 is a single integrally forged or molded metal material, as opposed to being formed from multiple parts jointed or fastened together. Although preferred embodiments of the present rescue bar, as well as halligan bar, are preferably forged from a single piece of steel, alternative compositions may employ other suitable materials that are harder than the materials they will be used to demolish such as, for example, wood, aluminum, or other materials. The materials may in some embodiments include components that are welded or otherwise fastened.

[0064] Now referring to FIGS. 3A and 3B and best shown in FIG. 4, rescue bar 10 includes an upper portion of open space 6K configured with an angled notch and adjacent planar surface adapted for coupling with and thereby enabling manipulation of hexagon headed fasteners such as, for example, used for fire hydrant and hose fittings and connectors, and may be adaptable to other fasteners and/or suitably configured hardware or objects.

[0065] As mentioned above, rescue bar 10 may be utilized to pry open, break apart or otherwise demolish enable forcible entry by placing chisel end 6H in a gap, such as, for example, between a door and a corresponding doorjamb, or on a surface and strike contact face 6I is struck by a hammer or other tool, thus, driving chisel end 6H. The elongated positioning of chisel end 6H beyond lower jaw 6C enables deep penetration of the strike area.

[0066] In some embodiments, open space 6K may be used to manipulate pentagonal nuts on fire hydrants, or loosen, tighten, or otherwise manipulate nuts or other fasteners having standard configurations. In some of such other embodiments, pair of jaws 6A can have two or more stepped, angled or otherwise configured surfaces that correspond or mate with surfaces of the fastener. For example, pair of jaws 6A and/or open space 6K may be configured for adaptive engaging to a corresponding depth and length, slope or taper or composition of target material surfaces.

[0067] Rescue bar 10 and halligan bar 20 may be provided in a number of lengths, typically ranging between 18-54 inches, but can also be shorter or longer. They may be composed of an integrally molded metal material, or include multiple parts jointed or fastened together. The rescue access tool, including the handle, the head end, the bent end pry bar, and/or other portions of the rescue access tool, may comprise a single integrally molded metal material. Rescue bar 10 and halligan bar 20 are manufactured to weigh between 6 to 12 pounds.

[0068] To provide further advantages of increased speed and force for expediting entry to rescue victims and mitigate damage during emergencies, rescue bar 10 is configured for mated engagement with corresponding ends of respective fork lever 16 and pick adze 14 ends of halligan bar 20.

[0069] As shown in FIGS. 6-9, respective opposing ends of rescue bar 10 and halligan bar 20 can be coupled to provide at least three extended interlocks 100′, 100″, 100′″. FIG. 10 shows rescue access tool 100″″ paired in parallel juxtaposition when not in use.

[0070] In a clasped interlock 100′ shown in FIGS. 6 and 6A, sickle blade 4 is inserted through the space between the two prongs of fork lever 16. The prongs are seated on respective recesses extending from space 4C such that the inner edges of fork lever 16 prongs are in abutted engagement with corresponding surfaces of the side walls such that fork lever 16 is wedged in mated engagement against respective raised surface of lower claw 4A and extended upper claw 4B and the intermediary portion edge 4D of sickle blade 4. When used in clasped interlock 100′, the extended length and commensurate force imparted to head end 6 and adze 14 enable a commensurate increase in the force imparted to the materials, reducing the amount of strikes and time for forcible entry.

[0071] In stepped interlock 100″ illustrated in FIGS. 7 and 7A, rescue bar 10 and halligan bar 20 are coupled by seated engagement of pick adze 14 within gap 6D between upper jaw 6B and lower jaw 6C of paired jaws 6A in head end 6. Pick adze 14 is further secured by seating pick 14B in notch 6E of wedge end 6H when rescue bar 10 and halligan bar 20 are paired in an extended stepped interlock. In addition to imparting additional force and power for use of fork lever 16 and sickle blade 4, simultaneously positioning claw 4 on a lower level and an outer edge of fork lever end 16 at an elevated level positions the crown surface of head end 6 so as to provide a step up to the elevated level.

[0072] In another functionality provided by pairing of rescue bar 10 and halligan bar 20 to form interlock 100″′ illustrated in FIGS. 8 and 8A, the pair of aligned channels 6L of head end 6 of rescue bar 10 are configured for coupled engagement with a pair of aligned prongs of a fork lever end of a halligan bar wherein the rescue bar and the halligan bar are in extended paired interlock 100″′ and in a side-by-side parallel juxtaposition 100″″ securely coupling halligan bar fork lever end 16 in abutted engagement between the aligned channels 6L of head end 6 of rescue bar 10 for facilitating storage and transport of the rescue access tool. In parallel juxtaposition 100″″, strike contact face 6I is faced outwardly thereby enabling setting the lower portion of strike contact face 6I and the back surface of upper crescent claw 4B in a stable position on a resting surface.

[0073] In addition to the compounded force imparted by the leverage of the rescue access tool provided by interlocks 100′, 100″, 100″′, the elevation imparted by the added length of handles 2 and 12. Thus raising the total handle length closer to shoulder height reduces the need to bend down and thereby lessens stress and possible injury to the back.

[0074] In some embodiments, recessed portions along the handle 2 and second handle 12 may further include a layer of slip resistant and/or padded grip material. Such grip materials may include, for example, from one or more types of plastic or rubber that provide increased grip and/or comfort for a user of a rescue access tool. In some embodiments, layers may be from a material (e.g., plastic, rubber, or other material) that provides impact or shock cushioning for a user's hands.

[0075] Rescue bar 10 and halligan bar 20 may be provided in a number of lengths, typically ranging between 18-54 inches. They may be composed of an integrally molded metal material, or include multiple parts jointed or fastened together. The rescue access tool, including the handle, the head, the bent end pry bar, and/or other portions of the rescue access tool, may comprise a single integrally molded metal material. In many embodiments, rescue bar 10 and halligan bar 20 is manufactured to weigh between 6 to 12 pounds and of a composition harder than the materials it is used to strike (e.g., wood, aluminum, or other materials).

[0076] While the invention has been described with reference to the certain illustrated embodiments, the words that have been used herein are words of description, rather than words of limitation.
