[0044]
[0045] As illustrated in
[0046] In order to keep the hinged latch 208 from protruding beyond the outer diameter of the cleaning rod 106, a narrow ledge 220 may be formed in the trailing edge of the pivot latch 208. This narrow latch may be positioned such that it comes to rest against an inner surface of the hollow shaft portion 212 such that it prevents the trailing edge of the pivot latch 208 from being forced beyond the outer surface of the cleaning rod 106 by the spring 216. This is illustrated in
[0047] A plurality of different cleaning devices may be connected to a cleaning rod 106 or cable using the engagement ridge and engagement latch arrangement described above. The cleaning device 104 shown is exemplary and it is not intended to represent the only such device that may be used in embodiments of the invention. Many other types of cleaning devices may be used, examples of which may include, but are not limited to, cleaning cloth loops, brushes, scrapers, and swabs. Additional embodiments of the invention may comprise a cleaning device interface that includes a member 204, an enlarged section 206, and an engagement groove 202 and that also comprises a threaded opening to allow for the attachment of threaded cleaning devices such that the convenience afforded to a user of the invention may be extended to other types of cleaning devices.
[0048] In addition to the embodiments described above and illustrated in
[0049] To conduct a gun barrel cleaning operation, a user may perform the described twisting motion to attach and remove cleaning devices without having to repeatedly twist to attach and detach cleaning devices as is the case when using known threaded attachment methods. In addition to attachment of cleaning devices, the invention may be applied to connect additional sections of barrel cleaning rods to accommodate longer barrels.
[0050] In addition to the features described above, embodiments of the present invention may be formed from a fiber reinforced plastic material. Such materials may result in a cleaning device that is less likely to damage a gun barrel, may be less susceptible to rust or corrosion, and may be less costly to produce as the result of efficient molding processes. Referring to
[0051] In order to increase the strength of a potential failure point at the junction of the member 204 and enlarged section 206, an arcuate shape may be formed at the transition of these two portions. An example of such a shape is illustrated at 506 of
[0052] As was noted above, the member 204 of the cleaning device 104 may be rectangular in cross section. This rectangular shape performs two functions, the first is to prevent the cleaning device from rotating in relation to the cleaning rod and second, the rectangular shape serves to orient the shaft such that one of the two engagement grooves (which are located on opposite sides of the cleaning device 104) aligns with the hinged latch 208 to secure the cleaning device. The member 204 may comprise a substantially rectangular cross section, though any cross section is contemplated, and may be tapered from the point at which the first shaft connects to the second shaft portion of the cleaning device 104 to the end of the shaft. This taper serves to more securely connect the cleaning device into the axial recess 212 of the cleaning tool 100. A cross section of the axial recess 212 is illustrated in
[0053] In addition to the tapered latch, a raised portion may be formed on an outer portion of the hinged latch as illustrated in
[0054]
[0055] A shaft section 304 may extend between the member 204 and the enlarged section 206. In exemplary embodiments, the shaft section 304 is substantially circular in cross section, though any cross section is contemplated. In exemplary embodiments, the shaft section 304 has a larger cross section than the member 204, but a smaller cross section than the enlarged section 206.
[0056] The cleaning device 104 may further comprise a securing member 306 configured to be press fit or otherwise placed in close proximity to the enlarged section 206. In exemplary embodiments, the securing member 306 is shaped as a hollow cylinder such that an aperture 308 is formed in the center thereof. The aperture 308 may be sized such that the inner diameter of the securing member 306 is substantially the same as the outer diameter of the shaft section 304. In this way, the securing member 306 may be securely and slidably mounted to the shaft section 304. The securing member 306 may likewise comprise ridges or otherwise match the profile of the enlarged section 206, though such are not required.
[0057] The securing member 306, the shaft section 304, the enlarged section 206, or some combination thereof may be configured to prevent the securing member 306 from traveling beyond a certain location on the shaft section 304 such that a gap 310 is maintained between the securing member 304 and the enlarged section 206. The gap 310 may be sized to accommodate a cloth 316. In exemplary embodiments, the gap 310 may be 0.015 inches in size, though any size is contemplated.
[0058]
[0059] In other exemplary embodiments, the securing member 306 may be configured to be secured to the notched section 312. For example, but not to serve as a limitation, the aperture 308 may be sized such that the securing member 306 may be wedged partially or wholly onto the notched section 312. In this way, the cloth 316 may be sandwiched between the securing member 306 and the enlarged section 206.
[0060]
[0061] In other exemplary embodiments, the securing member 306 may be configured to be threaded to the threaded section 314. For example, but not to serve as a limitation, the securing member 306 may comprise corresponding threads around the inner diameter of the aperture 308 that permit the securing member 306 to be threaded to the threaded section 314. In this way, the cloth 316 may be selectively sandwiched between the securing member 306 and the enlarged section 206.
[0062]
[0063]
[0064]
[0065] The cloth 316 may be pre-treated or otherwise exposed to a cleaning substance or a lubricating oil, though such is not required. The cloth 316 may be attached to the cleaning device 104 as previously discussed. The cleaning device 104 may be attached to the distal end of the cleaning rod portion 106. The user may grip the handle 322 and push the cleaning device 104 axially down the barrel of the firearm 320. Similarly, the user may grip the handle 322 and pull the cleaning device 104 axially out of the barrel of the firearm 320. This process may be repeated to clean the barrel of the firearm 320. The cleaning device 104 may likewise be passed through or over other various portions of the firearm 320 for cleaning. For example, but not to server as a limitation, the cleaning tool 100 may instead be passed through the ejection port and down the barrel of the firearm 320. As another example, but again not to server as a limitation, the cleaning tool 100 may instead be passed into the interior grip chamber when the clip is removed.
[0066]
[0067] Regardless, the cleaning device 104 may be configured to be selectively secured to the cleaning rod portion 106. In this way, the cleaning device 104 may be moved throughout the barrel for cleaning, particularly in an axial direction through a gun barrel. A handle 322 may be attached to the cleaning rod portion 106 to facilitate the axial movement by a user.
[0068] A shaft 324 may extend from the distal end of the enlarged section 206. In exemplary embodiments, the shaft 324 may have a substantially circular cross section, though any shape is contemplated. The cross section of the shaft 324 may be smaller than the member 204, though any size is contemplated. A first and second protuberance 326 may extend substantially perpendicular from the sides of the outer surface of the shaft 324. The first and second protuberances 326 may so extend near the distal end of the shaft 324, though any location along the shaft 324 is contemplated. In exemplary embodiments, the first and second protuberance 326 may extend from substantially opposite sides thereof, though any location is contemplated. It is contemplated that any number of protuberances 326 may be utilized with the present invention. The protuberances 326 may have a substantially rectangular cross section, though any shape is contemplated.
[0069]
[0070] Regardless, the securing member 306 may comprise a slotted section 327 configured to accommodate the protuberances 326, which may be rotated into the slotted section 327. In exemplary embodiments, the securing member 306 may further comprise a post 328 located on or within each of the slotted sections 327. The post 328 may be located such that the posts 328 frictionally engage the protuberances 326 when the securing member 306 is rotated. In exemplary embodiments, the slotted section 327 may be located entirely within the body of the securing member 306. In other exemplary embodiments, the slotted section 327 may be located on a distal end of the securing member 306, though any location is contemplated.
[0071]
[0072]
[0073] The slots 327 and the protuberances 326 may be respectively located such that when the securing member 104 is mounted to the shaft 324, a gap 310 remains between the proximal end of the securing member 104 and the distal end of the enlarged section 206. The gap 310 may be configured to accommodate a cloth 316, which may be secured over the shaft 324 and within the gap 310. The cloth 316 may be sized such that when so secured it extends therefrom to facilitate contact with the barrel when moved axially therethrough.
[0074] The cloth 316 may be sized and configured to clean the barrel assembly when moved therethrough. For example, without limitation, the location of the gap 310 for the cloth 316 between the securing member 104 and the enlarged section 206 may cause the cloth 316 to be pressed against the barrel. In exemplary embodiments, when the cleaning tool 104 is inserted into the barrel assembly, the cloth 316 may be folded back against the enlarged section 206 or another component(s). The cloth 316 may then be sandwiched between the enlarged section 206, or another component(s), and the inner wall of the barrel. As the cleaning tool 104 is axially advanced into the barrel, the cloth 316 may be continually pressed against the inner diameter of the barrel to facilitate cleaning. Upon axial retraction of the cleaning tool 104, the cloth 316 may either remain pressed against said component, or may shift to be sandwiched between the securing member 306, or another component(s), and the barrel assembly. This may facilitate the use of both sides of the cloth 316. Regardless, as the cleaning tool 104 is retracted axially, the cloth 316 may remain pressed against the inner diameter of the barrel to facilitating cleaning. Additionally, the cleaning tool 104 and the attached cloth 316 may be rotated. The cloth 316 may then be removed and may be replaced as needed, for example without limitation, when said cloth 316 is worn or excessively dirtied with deposits. The process of inserting the cleaning tool 104, moving it axially along the barrel, and removing it may be repeated. In exemplary embodiments, the cleaning tool 104 may be rotated before reinsertion, though such is not required.
[0075] Any embodiment of the present invention may include any of the optional or preferred features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. Having shown and described exemplary embodiments of the present invention, those skilled in the art will realize that many variations and modifications may be made to the described invention. Many of those variations and modifications will provide the same result and fall within the spirit of the claimed invention. It is the intention, therefore, to limit the invention only as indicated by the scope of the claims.
