The present disclosure is directed to a multifunctional tool which may be used, for example, by firefighters.
Firefighters may be assigned to a number of different emergency calls. Sometimes firefighters are the first emergency responders on a scene and may take on additional duties as required by the situation. For example, a firefighter may be called to rescue people or animals from a burning structure, may be called to the scene of a vehicular accident to ensure the health and safety of passengers and to reduce the likelihood of a damaged car erupting in flames. Each type of emergency may require multiple tools. For example, a firefighter called to a burning structure may be called on to attach a hose to a fire hydrant, to gain access to a structure (which may include prying a door open, using a screw or other driver to remove an object, breaking glass, or the like), to cut cables or wires to reduce the likelihood of further fires erupting, or the like. Each of these actions and more may require specialized tools. Carrying even a portion of the tools that may be used for a particular job may be difficult. Furthermore, some of these tools may be designed for intense conditions and may thus have considerable weight associated with them. The amount of increased weight that a firefighter may carry around may slow the firefighter down in time-sensitive conditions, which may mean the difference between life and death as well as potential loss of property. In addition, if only some tools are being carried by a firefighter and additional tools are required while at a scene, the firefighter may need to return to the fire apparatus to retrieve additional tools, which also slows down progress and may likewise risk lives and property.
Thus, there is a need in the art for a tool that is usable by firefighters to achieve multiple objectives during an emergency situation.

The present disclosure describes a plier having multiple functions integrated into a single assembled component. The plier may be used by firefighters to reduce a quantity of tools to be carried to jobs. The plier provides significant benefits and advantages such as integrating a number of tools used in firefighting (e.g., eight firefighting tools) into a single component or tool, thus reducing a quantity of tools in a pocket or otherwise carried on a person, which also reduces additional weight transported by the person. This further reduces or eliminates additional trips to a fire apparatus to retrieve new tools, saving this time for life-saving and property-saving actions. The plier may be made to have a relatively wide handle to improve grip and comfort. The plier is designed to be easy to put in and remove from pockets or fastener assemblies located in or on firefighter turnouts, making it easily transported to both emergency and non-emergency operations.
Referring generally to the drawings, an exemplary multi-function firefighting tool, or plier, 100 is shown. The tool 100 includes multiple features or components which may be formed integral (i.e., monolithic) with the other components of the plier 100, may be formed separately from the other components and coupled thereto, or any combination thereof (e.g., some components may be formed integral, or monolithic, and other components may be coupled thereto, either removably or permanently). The components may be formed from a metal (e.g., steel or aluminum), plastic, other polymers, or any other material or combination of materials.
The tool 100 may also be referred to as a plier 100 as it includes features that function as a pair of pliers. Referring to
In some embodiments, the movable leg 104 may rotate relative to the fixed leg 102. In some embodiments, the movable leg 104 may move along an axis thereof relative to the fixed leg 102. In some embodiments, the fixed leg may be coupled to the movable leg 104 in any known manner and using any type of connector. In some embodiments, both legs 102, 104 may be movable relative to each other. The term “fixed leg” may simply indicate that a “movable leg” may move relative thereto and not necessarily that the leg is fixed in any position (e.g., the “fixed leg” may be referred to as a first leg, and the “movable leg” may be referred to as a second leg).
The fixed leg 102 includes a fixed handle 106 on a first side of the pivot point 114 and a lower jaw 110 on a second side of the pivot point 114, and the movable leg 104 includes a movable handle 108 on the first side of the pivot point 114 and an upper jaw 112 on the second side of the pivot point 114. In some embodiments, a movable leg may include a lower jaw and a fixed leg may include an upper jaw without departing from the scope of the present disclosure. The fixed handle 106 may be formed integral, or monolithic, with the lower jaw 110, and the movable handle 108 may be formed integral, or monolithic, with the upper jaw 112.
Rotation of the movable leg 104 relative to the fixed leg 102 may cause the upper jaw 112 to move towards (and potentially contact) the lower jaw 110 (and rotation of the movable leg 104 relative to the fixed leg 102 in the other direction may cause the upper jaw 112 to move away from the lower jaw 110). In that regard, an object may be clamped between the upper jaw 112 and the lower jaw 110, resulting in the jaws 112, 110 functioning as a pair of pliers.
The movable leg 104 may define an elongated slot 128 for receiving the pin 116, allowing the pivot point 114 to move relative to the movable leg 104 (i.e., along an axis defined by the elongated slot 128). The elongated slot 128 then provides for an adjustable distance between the lower jaw 110 and the upper jaw 112, making the plier 100 an adjustable plier. In some embodiments, the movable leg 104 may define protrusions 129 (e.g., lips, chevrons, ridges, or the like) adjacent to the elongated slot 128 which may define cutouts or slots 131 therebetween along the axis defined by the elongated slot 128. In that regard, the fixed leg 102 may define a protrusion (not shown) which may be received within a slot 131 defined by the protrusions 129. In response to the protrusion of the fixed leg 102 being received within a slot 131, the movable leg 104 may remain in a fixed position (along an axis defined by the elongated slot 128) relative to the fixed leg 102 (e.g., to allow relative rotation while reducing the likelihood of other relative movement). The protrusion of the fixed leg 102 may be removed from the slot 131 (e.g., by locating it within the elongated slot 128) and the movable leg 104 may then move along the axis defined by the elongated slot 128. In that regard, the protrusion of the fixed leg 102 may interface with the protrusions 129 to cause the upper jaw 112 to be in a desired location relative to the lower jaw 110. In that regard, the plier function of the tool 100 may be adjustable (e.g., to allow a distance between the upper jaw 112 and the lower jaw 110 to be adjustable based on a specific use of the plier function).

In some embodiments, the window punch 126 may extend in a direction substantially parallel to the elongated slot 128. In some embodiments, the window punch 126 may extend in a direction substantially perpendicular to a portion of the upper jaw 112 that contacts the lower jaw 110. Where used in this context, substantially refers to a direction that is parallel (or perpendicular) or within 10 degrees, 20 degrees, 40 degrees, 50 degrees, or the like thereof. In some embodiments, the window punch 126 may be located at various locations on the upper jaw 112. For example and as shown in
The window punch 126 may extend away from the respective jaw by a distance of, for example, 0.25 inches, 0.5 inches, 1 inch, 2 inches, or the like. In some embodiments, the window punch 126 may be designed to have a relatively blunted point to reduce the likelihood of unintended injury to the user. The window punch 126 may be used to break glass (such as a window) in such a way as to shatter or break the glass with minimal likelihood of injury to the user or damage to the tool 100 or property.
In some embodiments and referring to
In some embodiments, the movable handle 108 and the fixed handle 106 may each include any quantity of insert holes 130. For example, each handle 106, 108 may include between 0 and 10 insert holes, between 1 and 6 insert holes, 2 insert holes, 3 insert holes, 4 insert holes, or the like. The insert holes 130 may have any shape. For example and as shown, the insert holes 130 may have a round or cylindrical shape to receive objects having a circular or cylindrical shape. In some embodiments, the insert holes 130 may have a square or rectangular prism shape to receive objects having a square or rectangular cross section. In some embodiments, the insert holes 130 may include a hexagon or hexagonal prism shape (similar to the magnetic socket 124) to receive objects having a hexagonal cross section (such as the bit 125). In that regard, one or more insert hole 130 may function to receive a bit in a similar manner as the magnetic socket 124. In some embodiments, the insert holes may all have the same dimensions or shapes, and in some embodiments, the insert holes 130 may have different dimensions or shapes. For example, the fixed handle 106 may include 4 insert holes 130 including first and second insert holes having a circular shape and a same dimension (e.g., a same width), a third insert hole having a hexagonal shape with a first dimension (e.g., a width of a quarter of an inch), and a fourth insert hole having a hexagonal shape with a second dimension (e.g., a width of an eighth of an inch). Continuing the movable handle 108 may include 4 insert holes 130 including a first and second insert holes matching the shape, dimension, and location of the first and second insert holes of the fixed handle, a third insert hole having a squared shape with a first dimension (e.g., a width of a quarter of an inch), and a fourth insert hole having a squared shape with a second dimension (e.g., a width of an eighth of an inch).
The insert holes 130 may be designed to receive inserts for lugs usable to adjust valves (e.g., a lug wrench for opening and/or closing a valve such as a gas valve or a water valve, other equipment, or lugs for any other purpose). For example, lugs or pins may be inserted into two or more insert holes 130 and these lugs or pins may interface with a valve to facilitate opening or closing of the valve by cranking the plier 100 in a clockwise or counterclockwise direction. For example, a lug (not shown) may include two prongs extending outward therefrom. A first prong of the lug may be received by a first insert hole 130 (e.g., an insert hole defined by the movable handle 108) and a second prong of the lug may be received by a second insert hole 130 (e.g., an insert hole defined by the fixed handle 106). In some embodiments, both (or more) prongs of a lug may be received by insert holes of a single handle. For example, a first prong of a lug may be received by a first insert hole 130 of the fixed handle 106, and a second prong of the lug may be received by a second insert hole 130 of the fixed handle 106. After both (or more) prongs of the lug are received by respective insert holes 130, the lug may be used for its intended purpose (e.g., opening or closing a gas valve or water valve, or other equipment), for example, by rotating the tool 100 with the lug coupled thereto.
In some embodiments, the tool 100 may include an external clip or connector (not shown) designed to mate with (or otherwise retain in place relative to the tool 100) a lug (e.g., a lug wrench) to removably couple the lug to the tool 100. For example, the tool may have an external spring-loaded clip that exerts a force towards a handle 106, 108. A lug wrench may be designed to be received between the respective handle 106, 108 and the clip, such that the spring loading force retains the lug wrench in place between the clip and the handle 106, 108. As another example, a handle 106, 108 may define a protrusion extending therefrom, and a lug wrench may define a correspondingly shaped aperture. The aperture may be designed to receive the protrusion. A bulge or other feature defined by at least one of the protrusion or the aperture may resist separation of the protrusion from the aperture, thus removably coupling the lug to the tool 100. In that regard, when use of the lug is desirable, the lug may be removed from the external clip or connector and the prongs thereof may be positioned in the insert holes 130 for use.
In some embodiments, at least one of the fixed handle 106 or the movable handle 108 may define a compartment (i.e., they may be hollow). This feature may provide various advantages. First, the hollow nature of the handles 106, 108 may reduce a total weight of the tool 100. In addition, bits, lugs, or both may be stored in one or both handles 106, 108 to ensure they are available when needed.
