DETAILED DESCRIPTION

This disclosure is generally directed to a multi-use ax. The multi-use ax may comprise a head and a handle, each comprising multiple functionalities. In various embodiments, the head and the handle may comprise functionalities such as an anchor and attachment point, or belay loop, to allow a user to bail out of a hazardous environment. In various embodiments the head and/or the handle may comprise functionalities to provide a means by which a user may shut off gas and/or water at various sources.

The apparatuses and techniques described herein may be implemented in a number of ways. Example implementations are provided below with reference to the following figures.

FIG. 1 is a perspective view of a multiuse ax. The multi-use ax 100 may comprise a head 102, a handle 104, and an attachment point 106. As depicted in FIG. 1, the multi-use ax 100 comprises a horizontal axis 108 and a vertical axis 110.

In various embodiments, the components of the multi-use ax 100 may be manufactured via traditional manufacturing techniques. In some embodiments, the components may be manufactured by 3-D manufacturing techniques, casting, molding, forming, machining, composite manufacturing, or any other method of manufacturing. In some embodiments, the metal may be hardened during the manufacturing process.

In various embodiments, the head 102 may comprise a metal material (e.g., aluminum, steel, stainless steel, titanium, iron, alloys thereof, etc.), plastic material (e.g., high-density polyethylene, acrylic, melamine, polycarbonate, etc.), a composite material (e.g., fiberglass, carbon fiber, etc.), or combinations of the foregoing. In some embodiments, the head may be cast, formed or machined as a solid piece. In some embodiments, the head may comprise two or more pieces joined together. In at least one embodiment, the head 102 comprises steel, cast as a solid piece, and hardened to 45-55 on the Rockwell hardness scale. In some embodiments, the head 102 may comprise a hardness between 50 and 65

In various embodiments, the head 102 may have a length of 12 inches or less. In such embodiments, the multi-use ax may be sized to fit in a standard mounting bracket, which allows for quick access and easy removal when needed. In at least one embodiment, the head 102 may have a length of 10 inches. In yet other embodiments, the head 102 may have a length greater than 12 inches.

In various embodiments, the head 102 may have a width of equal to or less than 1.5 inches. In such embodiments, the head 102 may be a lighter weight, while also comprising a narrow profile, which may be useful in confined spaces. In at least one embodiment, the head 102 may have a width of 1 inch. In yet other embodiments, the head 102 may have a width greater than 1.5 inches.

As depicted in FIG. 1, the head 102 comprises an ax face 112, a pick 114, a top surface 116, and an anchor notch 118.

In various embodiments, the ax face 112 may comprise a sharp blade. In the illustrative embodiment, the ax face 112 comprises a blunt surface, flanked by beveled edges. In such an embodiment, a portion of the ax face 112 may be flat, oriented substantially perpendicular to the horizontal axis 108, while the beveled edges may be angled away from the flat portion (i.e., the blunt surface). The blunt surface may provide for a good striking surface for the ax face 112, while preventing the ax face 112 from getting pinched or wedged upon impact and/or penetration. Additionally, one possible benefit is that the beveled edges may allow a user to penetrate more material with each swing, allowing it to be a more efficient tool over at least sharp-edged conventional axes. Various embodiments contemplate that the blunt surface may be substantially flat, peaked, or curved along its length, along the edge between the bevels, or combinations thereof.

In some embodiments, the beveled edges may be angled between 15 and 85 degrees from the blunt surface of the ax face 112. In at least one embodiment, the beveled edges may be at a 45 degree angle from the blunt surface. In at least one embodiment, the blunt surface of the ax face 112 may comprise a width of about 0.5 inches, and may be centered on the ax face 112, between two beveled edges, each comprising a width of about 0.424 inches.

Additionally or alternatively, various embodiments contemplate that the ax face 112 may have a substantially smooth transition from the beveled edges to the blunt surface. For example, various embodiments contemplate that the beveled edges may provide a curved surface that may transition to the blunt surface where the blunt surface may be a flat portion or substantially curved. For example, various embodiments contemplate a smooth continuous curve from the edge of the ax face 112 through the blunt surface to the other edge of the ax face 112. Various embodiments contemplate that the surface may be defined by a piecewise continuous function where the boundary between the beveled edges and the blunt face may be smooth or sharp.

Additionally or alternatively, the ax face 112 may comprise a first portion of a blunt surface as well as a second portion of a sharp surface. For example, a top portion of the ax face 112 may comprise a blunt surface while a lower portion may comprise a sharp edge. Additionally or alternatively, a lower portion may comprise a blunt edge while a top portion may comprise a blunt surface.

In the illustrative environment shown in FIG. 1, the head 102 comprises a pick 114. The pick 114 may be used as an anchor point, a striking surface, a prying tool, and any other useful purpose. For example, the pick may be used as a striking tool to gain access to a particular room or building. For another example, the pick may be used as an anchor point. In such an example, a user (e.g., a firefighter) on a roof may embed the pick into the roof. Once embedded, the firefighter may stand on the top of the head, using the multi-use ax as a step. The firefighter may also embed the pick into the roof and hook into a belay loop at a distal end of a handle of the multi-use ax. In such an example, the firefighter may rappel off the roof to safety.

In various embodiments, the pick 114 may be oriented substantially along the horizontal axis 108 of the multi-use ax 100. In the illustrative embodiment shown in FIG. 1, the pick 114 may be oriented at an angle from the horizontal axis 108 of the multi-use ax 100. The angled pick may provide multiple benefits, such as, for example, increased leverage for prying and enhanced anchor setting. In various embodiments, the pick 114 may be angled between 5 and 45 degrees from the horizontal axis 108. In at least one embodiment, the pick 114 may be angled 10 degrees from the horizontal axis 108.

In various embodiments, the pick 114 may be tapered in width and/or height from a base to a tip. In various embodiments, the pick 114 may be substantially the same width and/or height for a majority of the pick (i.e., greater than 50% of the pick length). In at least one embodiment, the pick 114 may be the same width and/or height from the base to approximately 1 inch from the tip. The continuous dimension in the pick may allow for a more solid set into a striking surface. For example, a firefighter striking a roof may be able to better set the pick of the multi-use ax into the roof, thereby reducing undesirable movement, such as wobbling. The firefighter may thus be more confident in the multi-use ax holding steady, providing a more solid foot hold for the firefighter to climb and/or work on the roof.

In some embodiments, at least part of the top surface 116 may comprise a traction feature (non-slip surface) (e.g., surface texture (e.g., knurling, indentations, raised features, or combinations thereof), rubber, plastic, etc., or combinations thereof) to prevent an object from sliding off. In such embodiments, the non-slip surface on the top surface 116 may provide traction and further increase a user's safety when using the multi-use ax as a step or foot-hold. In the illustrative embodiment, part of the top surface 116 comprises a knurling pattern.

In various embodiments, the top surface 116 may comprise a cutout 120, centered on the top surface 116. In some embodiments, the cutout 120 may be used as a gas and/or water shutoff, providing the ability to open and close a gas and/or water valve. In the illustrative embodiment, the cutout 120 is substantially rectangular. The rectangular shape shown in FIG. 1 may be capable of fitting a majority of gas and/or water valves in use today. In at least one embodiment, the cutout 120 may be 1¼ inches long (i.e., along the horizontal axis 108), ½ inch wide, and ⅜ inch deep. However, it is understood that the cutout 120 may comprise a different size and/or shape as appropriate to fit other gas and/or water shutoff valves.

In various embodiments, the head 102 comprises a hole 122 going through the width of the head. In such embodiments, the hole 122 may be designed to receive the another tool, such as, for example, a Halligan style pry tool, thereby allowing the two tools to be easily carried together. In some embodiments, the hole 122 comprises a substantially rectangular shape, and is 2¼ inches long (i.e., along the horizontal axis 108) and ¾ inch wide. In yet another embodiments, the hole 122 comprises a substantially rectangular shape, and is 3⅛ inches long and ¾ inch wide. Though the hole 122 may be designed to receive another tool, the hole 122 may additionally be used for other purposes, such as, for example, water and/or gas shutoff, a belay loop, and a handle, to name a few.

In some embodiments, the head 102 may comprise an anchor notch 118. In such embodiments, the anchor notch 118 may provide an anchor point for a belay. For example, the anchor notch may be secured (e.g., hooked) around on a window ledge or window sill, creating a stable anchor point for belay. In yet another example, the anchor notch may be secured around a pipe, creating a stable anchor point.

In various embodiments, the anchor notch 118 may an angled side, configured to assist in pulling the tool tight against the surface to increase stability and security of the anchor point. In some embodiments, the angled side of the anchor notch 118 may also provide a breaching surface. In such embodiments, the bottom of the notch may come to a point, and may allow for penetration into a surface to increase stability of the anchor point. In various embodiments, the anchor notch 118 may comprise a non-slip surface or traction feature, such as, for example, a rubber coating or knurling. In such embodiments, the non-slip surface may increase the stability of the anchor point.

In the illustrative embodiment, the anchor notch 118 is located on the beard (i.e., the underside of the ax face, or the front of the head). In some embodiments, the anchor notch 118 may be located on the underside of the pick 114. In still yet other embodiments, the head 102 may comprise two anchor notches 118, one on the beard, and one on the pick. In such embodiments, the anchor notches 118 may be different sizes, thereby providing options for a user to have a better fit, and thus more stable, anchor point.

As depicted in FIG. 1, the multi-use ax comprises a handle 104, running substantially along the vertical axis 110 of the multi-use ax 100. The handle 104 may comprise a proximal end, closest to the head 102, and a distal end. In some embodiments, the handle 104 may be a straight handle, oriented along the vertical axis 110. In the illustrative embodiment, the handle 104 is ergonomically shaped, with curves on either side to provide optimal performance and comfort for the user. In some embodiments, the handle 104 may comprise additional ergonomic features, such as, for example, rounded edges, gripping surfaces (e.g., a rubber coating, a plastic coating, a textured surface, etc.), and a grip notch (i.e., to assist the gripping hand from slipping off the distal end of the handle).

The handle 104 may be attached to the head 102 at attachment point 106. The attachment point 106 may comprise a tendon and mortise, a press fit, a weld, or any other reasonable way to attach a head 102 to a handle 104. The attachment point 106 will be discussed in further detail below.

The handle 104 of the multi-use ax 100 may comprise a metal material, a plastic material (e.g., high-density polyethylene, acrylic, melamine, polycarbonate, etc.), a composite material (e.g., fiberglass, carbon fiber, etc.), a wood material, and combinations of the foregoing, among others. In at least one embodiment, the handle comprises grade 7075 aluminum.

In various embodiments, the handle 104 may comprise a series of relief cuts 124 in which material has been removed. The relief cuts 124 may decrease the weight of the handle, assist with balance, may increase the efficiency of a grip, to name but a few possible advantages. In at least one embodiment, the relief cuts 124 may be chamfered over to ensure there are no sharp edges.

In various embodiments, the handle 104 may comprise at least one wrench hole 126. In the illustrative embodiment, the handle 104 comprises two wrench holes 126, located in the relief cut 124 closest to the proximal end of the handle 104. In such an embodiment, a user may be able to apply a maximum amount of torque from the distal end of the handle 104. In some embodiments, the wrench hole(s) 126 may be located at a mid-point of the handle 104. In such embodiments, the user may be able to impart a force at the head 102 and the distal end of the handle 104, thereby increasing the torqueing force applied to the bolt. In other embodiments, the wrench holes 126 may be located at other locations on the handle 104.

In various embodiments, the wrench holes 126 may be sized and shaped to fit fire hydrant bolts. In such embodiments, the wrench holes 126 may be a pentagonal shape, a square shape, a hexagonal shape, an octagonal shape, or any other shape used for fire hydrant bolts. In at least one embodiment, the handle 104 may comprise two wrench holes 126, one being pentagonal and sized to fit a 1½ inch pentagonal fire hydrant operating nut, and one being square and sized to fit a 1¼ inch square fire hydrant operating nut.

In various embodiments, handle 104 may comprise a slot for webbing, oriented substantially along the vertical axis of the multi-use ax 100. In such an embodiment, the webbing may be run through the slot, and may secure additional gear and/or tools to the multi-use ax 100. For example, the webbing may secure a Halligan style pry bar to the multi-use ax, the pry end of the Halligan style pry bar being secured in the hole 122 in the head 102. In some embodiments, the slot may be located in a relief cutout 124.

In various embodiments, the multi-use ax 100 may comprise a belay loop 128 at the distal end of the handle 104. In the illustrative embodiment, the belay loop 128 is an unbroken loop of metal. In some embodiments, the belay loop 128 may comprise a carabiner with a gate. In such embodiments, the carabiner may be an automatic or manual locking carabiner, in order to increase the strength of the belay loop 128. Various embodiments contemplate that the belay loop 128 may be substantially integrated into the handle 104. For example, the handle 104 may comprise a grip section of the handle for gripping by a user. Various embodiments contemplate that the belay loop is located within a portion of the grip section. Additionally or alternatively various embodiments contemplate that the belay loop is located directly adjacent to a portion of the grip section. Additionally or alternatively, various embodiments contemplate that the belay loop is located in a substantially smooth extension of the handle past the grip section.

Various possible benefits of these locations of the belay loop may include sufficient strength in the belay loop 128 to support a user during an aggressive descent. Additionally or alternatively, the belay loop 128 may be integrated into the handle allowing an additional extension or feature to be added to the end of the handle 104 past the grip section. Additionally or alternatively, the belay loop 128 location may allow for use of the tool for other purposes without interference of the belay loop 128.

In some embodiments, the ax face 112 may be oriented at an angle between 5 and 45 degrees from the vertical axis 110. In at least one embodiment, the ax face 112 may be oriented at a 5 degree angle from the vertical axis 110

In various embodiments, the ax face 112 may comprise a blunt surface centered between beveled edges 202. In some embodiments, the beveled edges 202 may be oriented at angle between 15 and 85 degrees from the flat surface. In at least one embodiment, the beveled edges 202 are oriented at a 45 degree angle from the blunt surface. In other embodiments, the ax face 112 may comprise a sharp edge.

In the illustrative embodiment, the head 102 may comprise a hole 122 and/or an additional hole 204. In such embodiments, the hole 122 and/or the additional hole 204 may be configured to house an additional tool, such as one to supplement the multi-use ax 200. For example, the hole 122 and/or additional hole 204 may be configured to house a Halligan pry tool. The Halligan pry tool, together with the multi-use ax 200 striking tool, may create a set of “irons” used in forcible entry evolutions.

In various embodiments, the hole 122 and/or the additional hole 204 may be configured to be used as a shutoff, such as for a water and/or gas shutoff valve. In some embodiments, the hole 122 and/or the additional hole 204 may be configured to be used as a wrench.

In various embodiments, the pick 114 may be oriented substantially along the horizontal axis 108. In the illustrative embodiment, the pick 114 is oriented at an angle from the horizontal axis 108. The angle may comprise any angle between 5 and 45 degrees from the horizontal axis. In at least one embodiment, the pick 114 is configured 10 degrees from the horizontal axis.

In various embodiments, the pick 114 may be substantially the same width and/or height throughout a majority of the pick 114. In some embodiments, the pick 114 may be tapered in width and/or height from a base to a tip. In the illustrative embodiment, the pick 114 comprises a consistently tapered height, with each of the top and bottom sides angled to meet at a tip. In some embodiments, the pick 114 may comprise an inconsistent taper. In such embodiments, the top and the bottom sides may extend in a root section at one angle, and increase in angle at a tip section. In at least one embodiment, the pick 114 may be comprise a root section, with a consistent height, and a tip section in which the top and the bottom surfaces are angled to meet at a tip.

The head 102 of the multi-use ax 200 may be secured to a proximal end of a handle 104 at attachment point 106. As discussed above with reference to FIG. 1, the handle 104 may comprise relief cuts 124, wrench holes 126, and a belay loop 128.

In the illustrative embodiment, the handle 104 comprises four substantially ovular relief cuts 124. However, the handle 104 may comprise greater or fewer number of relief cuts 124. Additionally, the relief cuts 124 may be substantially circular, square, rectangular, or any other shape.

As depicted in FIG. 2, the handle may comprise one or more wrench holes 126. In some embodiments, the wrench holes may be sized and shaped to fit fire hydrant bolts. In such embodiments, the wrench holes 126 may be pentagonal and/or square. In at least one embodiment, the handle 104 comprises two wrench holes 126, one sized to fit a 1½ inch pentagonal fire hydrant operating nut, and one being square and sized to fit a 1¼ inch square fire hydrant operating nut.

In various embodiments, the handle 104 may comprise a slot 206 for securing additional equipment to the multi-use ax 200, such as, for example, with webbing. In the illustrative embodiment, slot 206 is a rectangular shaped slot, configured substantially parallel to the vertical axis 110. In some embodiments, the slot 206 may be ovular, circular, square, or any other shape. In various embodiments, the slot 206 may comprise a length and width capable of housing webbing, rope, twine, parachute cord, or any other material used for securing equipment.

In various embodiments, the handle 104 may comprise a belay loop 128. In some embodiments, the belay loop 128 is configured at the distal end of the multi-use ax 200. In some embodiments, the belay loop may comprise a carabiner 208 (e.g., an auto-locking carabiner, a manual lock carabiner, a non-locking carabiner). In such an embodiment, a user may be able to place a rope in the belay loop quicker and easier than feeding it in. For example, the gate of the carabiner may be opened, providing access to the belay loop, such that a rope could be placed inside of the belay loop at a mid-point of the rope (i.e., any point other than an end of the rope). In at least one embodiment, the carabiner 208 is capable of withstanding a force of at least 13 kN.

In the illustrative embodiment, the carabiner 208 comprises a lock 210. A benefit to having a lock 210 on the carabiner 208 is that the lock 210 increases the strength of the belay loop 128 (when the gate is closed) as compared to a non-locking carabiner.

As depicted in FIG. 2, the handle 104 of the multi-use ax 200 may comprise a spike 212. In such embodiments, the distal end of the handle 104 may come down to a tip, thereby providing a stable third point of contact while walking on a firm and/or slanted surface such as/for example, a roof Additionally or alternatively, when penetrated into a surface, the spike 122 may provide for an additional anchor point.

FIG. 3 is an isometric view of a head of a multi-use ax, such as multi-use ax 100. In various embodiments, the head 300 may comprise a metal material. In at least one embodiment, the head 300 comprises a solid piece of steel, hardened to 455-55 on the Rockwell hardness scale.

In various embodiments, the head 300 may comprise a length, L of 12 inches or less. In at least one embodiment, the head 300 may comprise a length, L of 10 inches. In some embodiments, the head 300 may comprise a length of greater than 12 inches. In various embodiments, the head 300 may comprise a height, H of 6 inches or less. In some embodiments, the head 300 may comprise a height, H of greater than 6 inches.

As shown in FIG. 3, the head 300 may comprise an ax face 302, an anchor notch 304, a pick 306, and a top surface 308.

In various embodiments, the ax face 302 may comprise a sharp blade. In the illustrative embodiment, the ax face 302 comprises a blunt surface, flanked by beveled edges 310. In some embodiments, the beveled edges 310 may be angled away from the blunt surface, at a 45 degree angle.

In various embodiments, the ax face 302 may be oriented substantially parallel to a vertical axis of the multi-use ax. In some embodiments, the ax face 302 may be oriented at an angle θ, from the vertical axis. In some embodiments, the angle θ may be an angle between 5 and 45 degrees. In at least one embodiment, angle θ may be about 5 degrees.

As depicted in FIG. 3, the ax face 302 may extend from the top surface 308 to a bottom surface. In various embodiments, the underside, of the ax face 302 (i.e. the beard) may be substantially perpendicular to the ax face 302. In some embodiments, the beard of the ax face 302 may comprise a tip, extending away from the ax face 302 at an angle. In such embodiments, the beard of the ax face 302 may comprise an anchor notch 304.

In various embodiments, the anchor notch 304 may be used as an anchor point, by securing the anchor notch 304 in a given material so it will not release or slip when weight is applied to the handle. In such embodiments, the angle on the beard side of the anchor notch 304 may be designed to pull the tool tight against the anchoring surface in order to create a stable and secure anchor point. For example, the anchor notch may be secured on the ledge of a window sill, with the handle oriented out the window. Once secured, a user may hook into a belay loop on the multi-use ax handle, and rappel out the window to safety.

Additionally or alternatively, the beard side of the anchor notch 304 may be used as an additional striking and/or breaching surface. For example, the sharp point combined with the angle of the anchor notch may be helpful in removing and breaching drywall or any other material. Once the anchor notch has breached the surface of a given material, the angle of the anchor notch may provide an efficient way to pull and remove the given material.

In some embodiments, the head 300 of the multi-use ax may comprise a pick. In various embodiments, the pick 306 may be oriented substantially along the horizontal axis of the head 300. In the illustrative embodiment shown in FIG. 3, the pick 306 may be oriented at an angle α from the horizontal axis of the multi-use ax 300. The angled pick may provide multiple benefits, such as, for example, increased leverage for prying and enhanced anchor setting. In various embodiments, angle α may be between 5 and 45 degrees. In at least one embodiment, the angle α may be 10 degrees.

In various embodiments, the pick 306 may be tapered in width and/or height from a base to a tip. In various embodiments, the pick 306 may be substantially the same width and/or height for a majority of the pick (i.e., greater than 50% of the pick length). In at least one embodiment, the pick 306 may be the same width and/or height from the base to approximately 1 inch from the tip. The continuous dimension in the pick may allow for a more solid set into a striking surface. For example, a firefighter striking a roof may be able to better set the pick of the multi-use ax into the roof, thereby reducing undesirable movement, such as wobbling. The firefighter may thus be more confident in the multi-use ax holding steady, providing a more solid foot hold for the firefighter to climb and/or work on the roof

In various embodiments, the base of the pick 306 may extend into a top surface 308. In some embodiments, at least part of the top surface 308 may comprise a non-slip surface or traction feature to provide extra friction for anything that comes into contact with the top surface 308. In such embodiments, the non-slip surface on the top surface 308 may provide traction and further increase a user's safety when using the multi-use ax as a step or foot-hold. In the illustrative embodiment, part of the top surface 308 comprises a knurling pattern.

In various embodiments, the top surface 308 may comprise a cutout, centered on the top surface 308. In some embodiments, the cutout may be used as a gas and/or water shutoff, providing the ability to open and close a gas and/or water valve. The cutout may be substantially rectangular, ovular, square, or any other shape capable of fitting a number of gas and/or water valves. In some embodiments, the cutout may be rectangular. In such an embodiment, the cutout may be capable of fitting a majority of gas and/or water valves in use today. In at least one embodiment, the cutout may be rectangular, and 1¼ inches long, ½ inch wide, and ⅜ inch deep.

In various embodiments, the head 300 may comprise at least one hole 312, extending though the width of the head 300. In some embodiments, the hole 312 may be designed to receive and secure another tool, such as, for example, a Halligan style pry tool, thereby providing a means by which two tools may be easily carried together. Additionally or alternatively, the hole 312 may be designed as a belay loop, thereby providing a user with yet another means by which they may anchor into the multi-use ax.

In the illustrative embodiment, head 300 comprises a single hole 312, the single hole comprising a substantially rectangular shape.
