DETAILED DESCRIPTION
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
Solid state tools (“SSTs”) are hand tools that have no moving parts and are frequently made from a single piece of material. SSTs are typically very durable and easy to manufacture.
The SST system or kit disclosed herein includes two or more SSTs that can each be used individually, that can be coupled together for use as a combined tool, and that can be coupled together in a compact storage configuration. Such a system is particularly helpful as a field-carry or field-use system for a variety of specific users or users. For example, as described in more detail below, the SST system can be configured to provide a variety of tools usable with firearms (e.g., firearms in general or a particular family or type of firearms. Other SST systems can be configured to provide a variety of tools usable with cars (e.g., cars in general or particular makes and/or models of cars), bicycles (e.g., bicycles in general or particular makes and/or models of bicycles), motorcycles (e.g., motorcycles in general or particular makes and/or models of motorcycles), skateboards (e.g., skateboards in general or particular makes and/or models of skateboards), boats (e.g., boats in general or particular makes and/or models of boats), sporting equipment (e.g., sporting equipment in general, specific types of sporting equipment, like a bow, and particular makes and/or models of sporting equipment). Other SSTs systems can be configured to provide a variety of tools frequently used in various activities or by various types of users including hiking, camping, and other outdoors activities, skilled tradespeople (e.g., electricians, plumbers, etc.), military personal, first responders, etc.
The SST system 100 illustrated in the exemplary embodiment of FIGS. 1-35 is intended to allow a user to service a firearm in the field. The SST system 100 is intended to service firearms of the AR family of rifles, including AR-15, AR-10, M-16 and M-4 rifles. The SST system 100 may replace an ad hoc personal collection of tools used to service the firearm in the field. For example the user may need to adjust, tighten or disassemble various components of the firearm while in the field. A small, compact and relatively lightweight tool system enables the user to make these adjustments or disassembly the firearm in the field without needing the full-size tools typically found in an armory or workshop. The SST system 100 is intended to fit into a standard sized storage compartment that may be found in the grip or stock of a firearm, which facilitates its use as a field carry system. For example, the SST system 100 may be sized to fit into grips manufactured by Magpul Industries, including grips sold under the MOETM and MIADTM brands.
As shown in FIGS. 1-2, the SST system 100 includes a first SST or wrench 102, a second SST or wrench 104, and a third SST or torque arm 106. In the illustrated embodiment, a bit holder 108 is also included, though this component may be excluded in other embodiments. In other embodiments, an SST system may include two or more SSTs usable alone and in combination in manners similar to those described herein with reference to SST system 100. Each of the three SSTs 102, 104, and 106 is usable on its own as one or more specific types of tools. For example, the first SST 102 includes multiple wrenches; each sized and shaped differently to engage different types of fasteners. Additionally, two of the SSTs (e.g. the first SST 102 and the third SST 106) may be combined with one another (e.g. attached or otherwise connected to one another) to be used in together as a combination tool. For example, the third SST 106 may be connected to the first SST 102 in order to increase the amount of torque that a user can apply using one of the wrenches of the first SST 102. In some embodiments, the SSTs are fine blanked and finish machined to form the bodies of the SSTs. In other embodiments, the SSTs may be formed by injection molding (e.g., metal, plastic, etc.), casting (e.g., investment, die casting, etc.), or other appropriate tool forming process. In some embodiments, the SST system may include additional components or tools than those illustrated in the exemplary embodiment.
FIGS. 3-8 illustrate the first SST 102 or sight wrench according to an exemplary embodiment. The first SST 102 includes multiple tool structures. These tool structures include two open hex wrenches 110 and 112, a firing pin scraper/cleaner 114, an accessory flat head driver 116, a sight post wrench 118, and a closed hex wrench 120. In the illustrated embodiment, the open hex wrench 110 is sized at 3⁄8 inch, the open hex wrench 112 is sized at 3⁄4 inch, and the closed hex wrench 120 is sized at 3⁄8 inch. These sizes correspond to fasteners or other components of members of the AR family of rifles. For example, the 3⁄4 inch open hex wrench 112 is sized to engage a standard sized muzzle device (e.g. a flash hider or flash suppressor). In other embodiments, one or more of the hex wrenches may be sized differently. The firing pin scraper/cleaner 114 is used to scrape or clean a firing pin. The accessory flat head driver 116 is used to engage the adjustment or attachment mechanism of rail mounted accessories (e.g. a scope, a light, a sight, or other rail mounted accessory). The driver 116 may replace of a flat head screwdriver or a quarter for this task. The sight post wrench 118 is used to adjust a sight post of the fire arm. The sight post wrench 118 includes four protrusions. The sight post wrench 118 is fixedly attached to the body of the first SST 102 by a screw 122. In other embodiments, different methods of fixedly attaching the sight post wrench 118 to the body of the first SST 102 may be used (e.g., welding, etc.). The sight post wrench 118 is not pivotable relative to the body of the first SST 102. The sight post wrench 118 is not removable from the body of the first SST 102 without the use of additional tools.
FIGS. 9-12 illustrate the second SST 104 or buffer wrench according to an exemplary embodiment. The second SST 104 includes multiple tool structures. These tool structures include two open hex wrenches 124 and 126, a buffer tube wrench 128, and a closed hex wrench 130. In the illustrated embodiment, the open hex wrench 124 is sized at 1⁄4 inch, the open hex wrench 126 is sized at 1⁄2 inch, and the closed hex wrench 130 is sized at 3⁄8 inch. These sizes correspond to fasteners or other components of members of the AR family of rifles. In other embodiments, one or more of the hex wrenches may be sized differently. The buffer tube wrench 128 is sized and shaped to engage the buffer tube nut (i.e., a castle nut) from a member of the AR family of rifles. The second SST 104 also includes a magnet 132 in the illustrated embodiment. An angled or tapered surface 134 is located proximate the end 136 of the second SST 104 opposite the closed hex wrench 130. The surface 134 is shaped this way in order to fit in storage compartments that include a taper or narrowing in this direction (e.g., the tapering storage compartment frequently found in the grip of a rifle of the AR family).
FIGS. 13-18 illustrate the third SST 106 or torque arm according to an exemplary embodiment. The third SST 106 includes multiple tool structures. These tool structures include a scraper 138, a closed hex wrench 140, a bolt carrier scraper 142, a cleaning cable aperture 144 that includes a round hole or opening 146 and an elongated slot 148, and a male hex wrench 150. For example, a cleaning cable may be fed through the cleaning cable aperture 144, which may be used as a handle for pulling the cleaning cable through the barrel of a rifle. The cleaning cable aperture 144 may be configured to be used with any number or type of cleaning cable, including those manufactured by Otis Technology. The scraper 138 is a general purpose scraper and may be used to clean carbon or other deposits from a firearm. The bolt carrier scraper 142 is the profile of the arm of the third SST 106 and is sized and shaped to function to clean a bolt carrier. The cleaning cable aperture 144 is used to hold a cable cleaner. The cable cleaner may be inserted through the hole 146 and slid into the elongated slot 148 to secure the cable to provide the user with additional leverage on the cleaning cable when cleaning a firearm. In the illustrated embodiment, the male hex wrench 150 is press fit into an aperture 152 formed through the body of the third SST 106 and is further secured to the body with a screw 154. Other attachment mechanisms are possible including, welding, press fitting alone, and using a screw or other fastener alone. The male hex wrench 150 includes a threaded aperture 156 that allows various accessories to be attached to the third SST 106. For example, the threaded aperture 156 may have 8/32 inch threads, which is used to connect various standard sized cleaning accessories (e.g. picks, scrapers, brushes etc.) to the third SST 106. The third SST 106 also includes a magnet 158.
FIGS. 19-25 illustrate the bit holder 108 according to an exemplary embodiment. The bit holder 108 includes a main body 160 having two apertures 162 and 164 formed therethrough. Each aperture 162 and 164 is sized and shaped to receive a bit driver. As illustrated, two bit drivers 166 and 168 are provided (e.g. a #0 cross or Phillips bit driver 166 and T10 hexalobular bit driver 168). The bit holder 108 also includes a first coupling portion 170 sized and shaped like the open hex wrench 126 of the second SST 104, a second coupling portion 172 sized and shaped like the open hex wrench 110 of the first SST 102, and a flange or stop 174. The first coupling portion 170 is adjacent the body 160 and the second coupling portion 172 is located between the first coupling portion 170 and the flange 174. In some embodiments, the bit holder 108 is made from a resilient material which may help to reduce the noise (e.g. rattling) when the SST system 100 is stored within a storage compartment of a firearm.
The SST system 100 is usable in multiple modes of operation. In a first mode of operation the three SSTs 102, 104, and 106 are coupled to one another in a storage configuration. To couple the three SSTs 102, 104, and 106 together in the storage configuration, the male hex wrench 150 of the third SST 106 is first inserted through the closed hex wrench 130 of the second SST 104 and then through the closed hex wrench 120 of the first SST 102. The longitudinal axes of the three SSTs 102, 104, and 106 are aligned in the storage configuration. The magnets 132 and 158 of the second SST 104 and the third SST 106, respectively, magnetically engage with one another as well as the metal body of the first SST 102 to act as an additional connecting mechanism between the SSTs (i.e., in addition the connection provided by the male hex wrench and the closed hex wrenches of the SSTs). In embodiments including the bit holder 108, the bit holder is coupled to the first SST 102, the second SST 104, and the third SST 106 in the storage configuration. The first coupling portion 170 is received within the open hex wrench 126 of the first SST 102, the second coupling portion 172 is received within the open hex wrench 110 of the first SST 102, and the flange 174 overhangs and engages the outer surface of the first SST 102. This coupling acts as an additional connecting mechanism between the SSTs (i.e., in addition the connection provided by the male hex wrench and the closed hex wrenches of the SSTs).
In a preferred embodiment, the SST system 100 in the storage configuration has an overall width of about 0.6 inches, an overall length of about 2.95 inches and an overall height of about 1.2 inches. This relatively compact size of the storage configuration enables the SST system 100 to fit within a storage compartment of a firearm, in particular a storage compartment of an AR family rifle. This relatively compact size of the storage configuration also enables the SST system 100 to comfortably fit in a pants pocket. FIG. 36 illustrates a firearm grip 176 including a storage compartment 178 and a storage compartment cover 180. When not in the storage configuration, the magnets 132 and 158 may also be used as magnetic securing devices to hold pins, cotter keys, nuts, bolts, or other components removed from the firearm when servicing the firearm (e.g., in order to not misplace or lose these components).
In a second mode of operation the first SST 102 is used as a tool by itself. For example, the open hex wrench 112 is used to remove a flash suppressor from the firearm.
In a third mode of operation the second SST 104 is used as a tool by itself. For example, the buffer tube wrench 128 is used to remove the buffer tube nut from the buffer tube of the firearm.
In a fourth mode of operation the third SST 106 is used as a tool by itself. For example, cleaning cable aperture 144 is used to secure a cleaning cable to clean the muzzle of the firearm.
In further modes of operation, the third SST 106 is combined with an additional tool (e.g., the first SST 102, the second SST 104, the bit driver 166, the bit driver 168) and functions as a torque to increase the amount of torque the user can apply relative to the additional tool by itself. As shown in FIG. 37, in a fifth mode of operation, the first SST 102 is coupled to the third SST 106 and is used as a first combination tool 200. The male hex wrench 150 of the third SST 106 is inserted through the closed hex wrench 120 of the first SST 102 to couple the SSTs together as the first combination tool 200. A user is able to apply more torque with the open hex wrench 112 or other tool structures of the combination tool 200 than with the open hex wrench 112 of the first SST 102 by itself. For example, the user may be able to remove a sticky flash suppressor more easily with the combination tool 200 than with the first SST 102 by itself.
As shown in FIG. 38, in a sixth mode of operation, the second SST 104 is coupled to the third SST 106 and is used as a second combination tool 300. The male hex wrench 150 of the third SST 106 is inserted through the closed hex wrench 130 of the second SST 104 to couple the SSTs together as the second combination tool 300. A user is able to apply more torque with the buffer tube wrench 128 or other tool structures of the combination tool 300 than with the buffer tube wrench 128 of the second SST 104 by itself. For example, the user may be able to remove a sticky buffer tube nut more easily with the combination tool 300 than with the second SST 104 by itself.
In a seventh mode of operation, one of the bit drivers 166 and 168 is coupled to the third SST 106 and is used as a third combination tool. The base of the bit driver is inserted into the closed hex wrench 140 of the third SST 106 to couple the bit driver to the third SST 106. The third combination tool enables a user to apply greater torque with the bit driver than when using the bit driver on its own.
