While optimal for many firearm cleaning applications and tasks, the firearm cleaning tools listed hereinabove could still be more compact.
What is needed is a new type of more compact firearm cleaning tool which combines the advantages of a cable and/or rod based T Handle cleaning system.
A tapered cavity 291 (
As was shown in
Alternatively, rod 301 can be threadingly coupled to the female threaded end of connector 211.
In another embodiment, instead of the “O” rings or bands, the tool bit cavities can be undercut molded into the T-handle firearm cleaning tool body, to keep the bits in place. For example, there can be a hex undercut molded tool bit cavity.
The T-handle firearm cleaning tool body 201 can be made from any suitable material by any suitable manufacturing method. For example, it is contemplated that a T-handle firearm cleaning tool body 201 can be machined from any suitable material including a metal, such as, for example, an aluminum block or rectangular bar stock. However, more commonly, such as the exemplary tool of the drawings, the T-handle firearm cleaning tool body 201 can be made from, for example, ABS plastic (Acrylonitrile-butadiene-styrene copolymer), TPE, or PC (poly carbonate).
The T-handle firearm cleaning tool body can be made by any suitable manufacturing method. For example, the tool body can be injection molded, including injection molded with inserts. Where the body is made from a plastic or other polymer type material, such as, for example, elastomers, thermoplastics, polymers, and thermosetting polymers. one exemplary suitable method is manufacture by injection molding using one or more injection molding forms or casts.
The rod 301 can be cut and threaded from any suitable material. The exemplary rod 301 of the drawings was made from brass rod stock. Similarly, the exemplary female threaded receptacle 233 was also machined from brass stock.
The “O” rings 221 can be any suitable off-the-shelf O-ring of any suitable size to sit substantially yet manually removably within channels 1701 (
Any suitable tool bit receptacle can be used. The exemplary hex tool bit receptacle 231 is a chrome plated steel.
Flexible cable 213 is typically a steel woven cable. Flexible cable 213 can also be a memory flexible cable types which can (typically reversibly) retain certain desired bends. Typically, the wires of the cable are made from steel, such as, for example, stainless steel, galvanized steel, or zinc coated steel. The cable can be made from a coated cable and can be, for example, a pre-assembled coated aircraft cable wire, or any other suitable commercially available pre-assembled coated cable wire which is well-known in the art.
Tool bits, such as exemplary tool bits, Torx tool bit 261, #1 Philips tool bit 263, #2 Philips tool bit 265, and a flat head tool bit 267 are widely available as pre-manufactured bits, made from any suitable material of sufficient strength, typically a type of steel metal.
A T-handle firearm cleaning tool kit includes a T-handle firearm cleaning tool body 201 having a top surface 251, a bottom surface 253, at least two end surfaces, and at least two side surfaces 281, 283. The T-handle firearm cleaning tool body includes at least one tool bit (e.g. Torx tool bit 261, #1 Philips tool bit 263, #2 Philips tool bit 265, or flat head tool bit 267) having a tool bit base. At least one T-handle firearm cleaning tool bit cavity 1703 has an opening about a length of the tool bit (“about” includes the case where the tool bit cavity is shorter than the tool bit, such as, for example, where the tool bit sticks out at one end). At least one band (e.g. O-ring 221) encircles the T-handle firearm cleaning tool body over an opening of the at least one T-handle firearm cleaning tool bit cavity 1703. At least one tool bit receptacle 231 is disposed in a surface of the T-handle firearm cleaning tool, the at least one tool bit receptacle sized to accept the tool bit base (e.g. a hex receptacle sized to accept the hex base of the exemplary tool bits: Torx tool bit 261, #1 Philips tool bit 263, #2 Philips tool bit 265, and flat head tool bit 267). A tapered cavity 291 is disposed in either of the top surface 251 or the bottom surface 253, the tapered cavity 291 has a long tapered cavity axis substantially perpendicular to a longitudinal axis of the T-handle firearm cleaning tool body and a tapered cavity opening in each of two side 281, 283 surfaces to capture a cable or rod connector 211 (or, the cleaning tool 215, where cable assembly 203 is reversed) in at least one of a pull or push direction. The exemplary tapered cavity 291 includes a larger opening 293, a ledge or ridge 297 sized to stop motion of the connector in one direction within the tapered cavity 291, and a smaller opening 295.
Cable assembly 203 of
There can be any suitable crimped tip or connector on the end of cable assembly 203 opposite to connector 211. Or, there could be two crimped cleaning tips, where the crimped cleaning tip is captured in the tapered cavity 291 of the T-handle firearm cleaning tool body 201, such as a connector 211.
Cable assembly 203 of
Just as the T-handle firearm cleaning tool body 201 can store tool bits in tool bit cavities 1703, it is also contemplated that some or all of the tool bit cavities could be replaced by cleaning bit cavities to store a cleaning bit in the T-handle firearm cleaning tool body. As well there could be additional supplemental tool bit or cleaning bit cavities disposed in any suitable surface of a T-handle firearm cleaning tool body. Any tool bit or cleaning bit cavities may have an interference fit with the intended tool bit or cleaning bit, a band (e.g. an O-ring) to hold the tool bit or cleaning bit in the cavity, or any combination thereof.
It will be appreciated that variants of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
