Description

BACKGROUND OF THE INVENTION

1. Technical Field
The present invention relates generally to firearms and more particularly, to a rescue tool that may be removably mounted onto a firearm.
2. Description of Related Art
A wide variety of tools are commonly used by law enforcement personnel, firefighters, emergency medical personnel and military personnel to gain access to structures having secured entryways (for example, a locked door) that prevent easy entry. Such rescue/entry/breaching tools typically include one or more implements having structures intended for use in prying, cutting, puncturing and/or striking. For example, a “Halligan” bar is a well-known multi-purpose tool that can be utilized to gain entry through a locked door or other entry obstruction. A Halligan bar typically consists of an elongated shaft having a claw or fork on one end of the shaft, and a wedge and pick on the other end of the shaft. Either the fork or the wedge of a Halligan bar may be used to open a locked door by forcing them between the door and the doorframe, and prying the two structures apart. Other rescue/entry/breaching tools may include such features as forked prongs, blades, pikes, multi-pronged pry-bars and other wedge-shaped implements.
Military personnel and law enforcement personnel such as those deployed in S.W.A.T. teams, are often required to carry heavy loads during operations. Such loads may include communications equipment, body armor, extra magazines and ammunition, firearms and other weapons, medical supplies, optics, lighting equipment, food and water, and entry/breaching tools. As the weight of loads carried by law enforcement and military personnel increases, tactical effectiveness tends to correspondingly decrease. Thus, there are many advantages in taking steps to effectively reduce the overall weight of such loads. Accordingly, there is strong-felt need in the prior art to reduce the overall loads carried by law enforcement personal and military personnel required to carry both a firearm and one or more rescue/entry/breaching tools. At least one object of the invention disclosed herein is to meet such need.

DETAILED DESCRIPTION OF THE DRAWINGS

Several embodiments of Applicant's invention(s) will now be described with reference to the drawings. Unless otherwise noted, like elements will be identified by identical numbers throughout all figures. The invention(s) illustratively disclosed herein suitably may be practiced in the absence of any element that is not specifically disclosed herein.
Systems and devices for utilizing a firearm-mounted rescue tool are disclosed herein. It should be noted that while the exemplary embodiments of rescue tools and other components discussed herein are taught in association with their application in the context of firearms, the systems and devices taught herein could also be equally utilized in connection with other types of non-firearm mechanical devices that would benefit from the incorporation of the types of implements discussed herein.
Referring to FIG. 1, a perspective view of an M-16/M4/AR-15 type firearm (100) as known in the prior art. Such firearm typically include, amongst other components, a lower receiver (101), an upper receiver (102), a barrel (104) and a buttstock assembly (106). The upper receiver and lower receiver are removably connected to one another through the use of multiple pins (107) configured to be received by correspondingly sized apertures (109) formed onto the receiver assemblies. A hand guard (108) may be formed around the barrel to protect a user's hands from heat generated during operation of the firearm.
Still referring to FIG. 1 and in particular, exploded views of the lower receiver assembly (101) and buttstock assembly (106) of an M-16/M4/AR-15 type firearm. The lower receiver assembly includes a threaded aperture (110) formed on a rearward portion of the receiver, which is sized for receiving (and threaded for securing) a generally cylindrical receiver extension (also known in the art as a “buffer tube”) upon which an adjustable buttstock may be mounted. A buffer and buffer spring are sized for insertion into a cavity formed into the hollow receiver extension. A “castle nut” and receiver end plate aid in securing and aligning the receiver extension to/with the lower receiver. An adjustable buttstock (114) may be removably mounted onto the receiver extension (112), the length of said buttstock being adjustable by a user through use of a lever (122) attached to a spring-mounted bolt (124) configured to pass through holes formed into the receiver extension and buttstock.
Referring now to FIG. 2, perspective views of multiple embodiments of the firearm-mounted rescue tool. With particular reference to one illustrative embodiment of the rescue tool (202), the tool includes a hollow shaft (204) having a generally cylindrical shape. One end of the shaft has threads (206) formed on an outer surface for engaging a threaded aperture (110) found on a rearward end of a lower receiver (101). An insertion body (208) is formed on a second more rearward end of the tool. The insertion body (208) may be integrally formed to the shaft (204) or in alternate embodiments as discussed below, may be removably attached and user-adjustable to provide for various lengths of the tool as desired by a user.
As shown in FIG. 2, alternate embodiments of the rescue tool may include insertion bodies having various types of shapes and configured to perform various types of functions, while all falling within the scope of the present invention. With specific reference to the embodiment shown at 202, the insertion body (208) is formed to include a prying implement extending downward from the body (and shaft) in a generally perpendicular direction with respect to said body and shaft. The prying implement (210) is generally wedge shaped for insertion into, among other structures, the space between a door and a doorframe. Teeth (212) are formed on a surface of the prying implement, allowing for increased engagement with the surfaces upon which it is used (doors, windows, etc.).
It is contemplated that the insertion body may also include other surfaces having shapes and textures that may or may not be useful for the aiding in the entry of buildings, but which may have other advantageous uses. For example, an armorer's tool (214) is formed on the underside of the insertion body in one embodiment of the tool (202). The armorer's tool is semi-circular in shape and includes wedged notches for use in assembling and disassembling the barrel of an AR-15 type firearm. It is contemplated that the insertion body may be sized and shaped to include other types of structures that may aid rescue personnel, law enforcement personnel and military personnel in the performance of their respective duties and in repairing or maintaining their weapons.
A further alternate embodiment of the rescue tool (216) includes an insertion body having a prying implement (217) formed to include forked prongs. The forked prongs (217) are useful not only in prying open various structures, but also in removing nails, screws and other fasteners that may be wedged between the prongs and pried loose. Other embodiments of the rescue tool (226) may include prying implements having prongs of various dimensions, depending upon the function for which they are intended. An even further alternate embodiment of the rescue tool (218) includes an insertion body having a prying implement (219) formed to include an axe like blade and pike (220). Both the blade and the pike may be utilized to break or otherwise puncture structural surfaces of entryways. An even further alternate embodiment of the rescue tool (228) may include an insertion body having a plurality of prying implements (229), each prying implement extending downward in a generally perpendicular orientation with respect to the insertion body and shaft. Ridges formed on the prying implements may be included to provide for increased grip on structural surfaces. It should be noted that while the embodiments discussed herein feature prying implements extending from the insertion body and shaft in a generally downward direction, it is contemplated that other alternate embodiments of the rescue tool may include prying implements or gripping implements having other orientations with respect to the insertion body and shaft, and may extend at various angles from the insertion body and shaft other than perpendicular, depending on the particular function of the implement.
An even further embodiment of the rescue tool (222) includes an insertion body that, as discussed in more detail below with reference to FIG. 9, is removably attached to the shaft of the tool and is configured for user-adjustment (adjustment of length). A wedge-shaped prying implement extends downward from the insertion body and shaft in a generally perpendicular direction. The prying implement terminates at a sharpened point, allowing for insertion into tight spaces. Ridges or “teeth” are formed onto a forward surface of the prying implement, allowing for a better grip on structural surfaces. As discussed in further detail below, a user-actuated lever (224) is connected to the insertion body, allowing the user to adjust the length of the rescue tool. Using the lever, a user may move a spring-loaded bolt disposed within a hole in the insertion body, into one or more holes formed into the shaft.
A collapsible, user-adjustable rescue tool provides rescue, emergency medical, law enforcement and military personnel an advantage not seen in prior art rescue, breaching and entry tools. Namely, the tool may be carried in a shortened mode when in transit or otherwise not in use, but may be lengthened at the user's discretion if needed when entering a building. Allowing the user to lengthen the rescue tool provides the user with a longer lever arm, which in turn provides for increased prying effectiveness (due to increased torque). Law enforcement and military personnel may also adjust the length of the rescue tool for the purpose of using the tool as a defensive or offensive weapon if circumstances of use so warrant. Another advantage of the rescue tool being configured for removable mounting is that the tool may be interchangeably used with a firearm buttstock. More specifically, a user may mount either a buttstock or a rescue tool on his or her pistol, depending on the circumstance facing the user at that particular moment.
Referring now to FIGS. 3, 4, 5, 6, 7 and 8, perspective views of the alternate embodiments of the rescue tool as shown in FIG. 2, said rescue tools being removably mounted to the rearward end of an AR-15 type pistol (100). The rescue tool having an outer shaft end that is threaded, is configured for mounting onto the correspondingly threaded aperture formed on the rearward end of a lower receiver of an AR-15 type pistol. A standard castle nut and receiver end plate may be used to secure and align the rescue tool to/with the lower receiver. Although not an essential feature of the present invention taught herein, it should be noted that the embodiments of the rescue tool include an insertion body having at least one outer surface having a substantially flat portion, preferably rearward facing, that is free from sharpened edges or points. The rearward facing substantially flat portion of the rescue tool may be used as a pounding implement. Additionally, the rearward facing substantially flat portion of the insertion body may be used to stabilize the pistol when aiming and/or firing said pistol.
It should be noted that the rescue tool may be constructed out of any number of materials. Non-limiting examples of the types of materials that may be utilized to construct the rescue tool include steel and other metals and metal alloys, and polymers. Those of skill in the art will appreciate that a number of factors should ideally be considered when choosing the type(s) of materials used to construct the rescue tool. Such considerations may include various material properties such as weight, specific modulus, strength, elasticity, hardness, melting point and electrical conductivity. In various embodiments of the rescue tool, the shaft of the tool may be constructed of a different material than the material(s) chosen to construct the insertion body. If formed separately during construction of the rescue tool, the insertion body that is to be integrally attached to the shaft of said tool, may be welded or otherwise permanently or semi-permanently connected to the shaft. With respect to the embodiment (222) shown in FIG. 8, the insertion body is removably connected to the distal end of the shaft of the tool as discussed further below.
Referring now to FIG. 9, an exploded view of the alternate embodiment (222) of the firearm-mounted rescue tool of the present invention as shown in FIG. 8. The rescue tool (222) includes a substantially cylindrical shaft (904) having one end with threaded grooves (906) formed thereon for engaging a correspondingly threaded aperture formed on a firearm lower receiver. It should be noted that while the embodiments of the rescue tool taught herein include rescue tools having substantially cylindrical shafts, it is contemplated that alternate embodiments of rescue tools may have shafts or other support structures, having various other types of shapes which may or may not be cylindrical or hollow, depending on whether it is necessary to accommodate a buffer, spring or any other type of firearm component, and further depending on the type of firearm to which it will be mounted. Likewise, although embodiments of the rescue tool discussed herein include a threaded end for mounting onto an AR-15 type pistol, alternate embodiments of the rescue tool may connect, attach to, mount to, or otherwise fasten to a portion of a firearm or other device by any known or heretofore unknown means.
Still referring to FIG. 9, extending downward from the insertion body in a generally perpendicular orientation, the prying element (923) is generally wedge shaped and terminates at a substantially sharpened point useful for insertion into tight spaces such as doors and windows. Grooves (926) formed on a forward facing surface of the prying implement aid in the tool's effectiveness in prying. The insertion tool includes a spring-loaded, lever-actuated mechanism that permits a user to adjust the length of the rescue tool, effectively providing for a telescoping/collapsing rescue tool. Formed on the underside of the insertion tool is a protrusion upon which a lever is mounted via a bolt (924) and nut/pin (927). A spring (925) is used to bias the bolt (924), which passes through holes formed in the insertion tool and shaft of the tool, said holes formed in predetermined positions, allowing for the insertion body to be locked at certain lengths along the rescue tool shaft at the discretion of the user. It is contemplated that other mechanisms for permitting adjustment of the rescue tool length to be implemented in alternate embodiments of the rescue tool. By way of example, other alternate embodiments of the rescue tool may utilize an adjustable clamp formed around the insertion body, allowing a user to tighten or loosen the clamp, thereby increasing or decreasing the ease by which the insertion body may slide along the shaft of the rescue tool.
