This non-provisional application claims priority under 35 U.S.C. § 119(a) to Korean Patent Application No. 2004-0156549-42 filed on Apr. 16, 2004, which is herein incorporated by reference.
FIELD OF THE INVENTIONThe present invention relates to an improved collapsible gun cleaning rod and more particularly to a collapsible gun cleaning rod formed of several tubular sections which can be folded into a collapsible state for convenient storage.
Various types of collapsible gun cleaning rods are known in the art. Generally, it is desirable or absolutely necessary to clean a gun barrel in a field camp, although a sportsman's firearm is typically cleaned at home. Usually, if a gun barrel bore becomes clogged with mud or snow while a sportsman is hunting, the hunter must remove the obstruction from the gun bore for his own safety. The firearm industry has long sought easy to carry, emergency cleaning rods for field cleaning firearms under adverse conditions. Conventional gun cleaning rods contain several tubular sections a tension cable disposed within the sections, a handle, and a cleaning brush. For example, U.S. Pat. No. 5,775,021 to Weiss discloses several tubular sections that can be folded together to form a compact package for storage. Running through the tubular sections is a tension cable provided with an enlargement abutting a shoulder disposed in the tubular element at the proximal end of the cleaning rod (
Korean Utility Model Patent 20-152,599 discloses a stick for cleaning the muzzle of a gun which includes several tubular sections, a tension cable extending through the sections, and a handle screwed to the proximal end of the stick. U.S. Pat. No. 2,070,844 to Riley discloses a cleaning rod for firearms, in which a threaded tubular element in
U.S. Pat. No. 3,402,950 to Hertzberg and U.S. Pat. No. 6,1245,235 to Emerson et al. disclose a rod for use in the barrel of a gun. Each of the rods has a pivoted handle that can be positioned to form a “T” with the rod or stowed against the side of the rod. U.S. Pat. No. 2,379,577 to Harsted, U.S. Pat. No. 2,705,015 to Langlais, U.S. Pat. No. 3,669,133 to Hyman, and U.S. Pat. No. 3,963,037 to Clark disclose additional examples of rods or poles formed of tubular sections which contain a strand connector extending through the sections.
However, when such conventional gun cleaning rods are used for a long time, the tension cable tends to stretch, the screw threads become worn, and the handle does not freely move. Also, such conventional gun cleaning rods do not disclose effective mechanisms for applying and relaxing the tension in the strand connector and for freely rotating the tubular sections while a user is cleaning a gun barrel bore.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to provide an improved collapsible gun cleaning rod which eliminates the above problems encountered with conventional gun cleaning rods.
Another object of the present invention is to provide a collapsible gun cleaning rod formed of several sections that can be folded in a collapsed state for convenient storage such as packing storage disposed on a gun stock.
A further object of the present invention is to provide a gun cleaning rod having several tubular sections with ends that fit into the end of an adjacent section. Mounted by threads to the distal end section is a short rod with a mechanism for holding a cleaning patch. The proximal end section is formed of two tubular elements that are coupled together by threads. The first of these tubular elements supports a tubular handle which moves relative to the tubular element between a folded position aligned with the tubular element and an extended position in which it forms a “T” with the tubular element and serves as a handle for the cleaning rod. The second of the tubular parts includes a distal end that fits into the end of the succeeding tubular section. An inextensible strand connector extends through the tubular sections with one end of the strand fastened to the distal end section. The proximal end of the cleaning rod is provided with an enlarged section disposed within the first tubular part of the proximal end section. The enlarged element engages a compression spring seated on a shoulder in the first tubular element. When the first tubular element is turned in a direction to extend the second tubular element, the spring applies tension to the strand so that when the tubular sections are fitted together, the cleaning rod is made rigid. When the first tubular element is turned in a direction to retract the second tubular element, the tension on the strand is relaxed so that the tubular sections can be separated and folded together into a collapsed, compact package.
Still another object of the present invention is to provide a collapsible gun cleaning rod which is simple in structure, inexpensive to manufacture, durable in use, and refined in appearance.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modification within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
BRIEF DESCRIPTION OF THE DRAWINGSThe present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
Reference is now made to
The plurality of tubular elongated sections contains ends which fit into the end of an adjacent section. As shown in
The tubular elongated support 60 carries a hollow tubular element 61 that is pivoted for movement relative to the tubular part between a folded position aligned with the tubular part and an extended end position in which it forms a “T” with the tubular part, and serves as a handle 70 for the cleaning rod. The first tubular elongated section 10 includes the endmost elongated segment 50 that fits into the end of the succeeding tubular section such as the fourth section 40 through a threaded segment 51.
An extensible strand connector 2 such as a stainless steel cable extends through the sections 10, 20, 30 and 40 and is fastened at one end to the distal end section 40 and at the other end to the tubular elongated support 60 which is provided with a spring 65 (
The compression spring 65 is seated on a shoulder in the tubular elongated support 60. When the tubular elongated support 60 is turned in a direction to retract the first tubular elongated section 10, the tension on the strand connector 2 is relaxed, whereby the tubular sections 10, 20, 30 and 40 can be separated and folded together into a collapsed compact package (not shown).
As shown in
The first tubular elongated section 10 includes an external support thread 11 for securely fastening section 10 with the internal thread 62 of the tubular elongated support 60. As shown in
Referring in detail to
The inextensible strand connector 2 extends through the first, second, third and fourth sections 10, 20, 30 and 40, and is connected to a rotor 66. When the sections 10, 20, 30 and 40 are assembled together with the tubular elongated support 60, the rotor 66 compresses the spring 65 against its bias, as shown in
Referring in detail to
As shown in
Referring in detail to
At this time, as shown in
Referring to
Even though the spring 65 is in a compressed state, the tubular sections 20, 30, and 40 can be rotated freely since the compressed spring 65, which is elastic, provides a degree of elasticity between the tubular portion. Also, the tubular elongated support 60 can be freely rotated through the supporting ring 67 which is movably disposed in the pair of elastic arms 72 of the handle 70. Therefore, the collapsible gun cleaning rod 1 of the present invention can be used to effectively clean the gun bore because the sections 20, 30 and 40, and the support 60 with the section 10 can be freely rotated to freely wipe the gun bore.
As shown in
Even though the inextensible strand connector 2 is stretched a little bit by long term use, because the strand connector 2 is connected to elastic spring 65, the elasticity of the spring 65 can compensate for the stretching of the strand connector 2. Therefore, the collapsible gun cleaning rod 1 according to the present invention is durable.
Referring in detail to
Thereafter, if the tubular elongated support 60 disposes within the opening slot 71 of the handle 70 is folded in the opening part direction, the tubular support 60 engages the pair of elastic arms 72. At this time, if the user pushes the tubular support 60 into the pair of elastic arms 72, the tubular support 60 is inserted into the opening slot 71 of the handle 70 as shown in
At this time, even though the tubular elongated support 60 is folded in the opening slot 71 of the handle 70, the elongated support 60 can not be separated from the opening slot 71 of the handle 70 due to the presence of internal stoppers 73 and 74. On the contrary, when the gun cleaning rod 1 is assembled, the stopping ring 67 is in contact with internal stopper 73 and erects, upright, the tubular elongated support 60 which extends from the pair of elastic arms 72, and the support 60, the sections 10, 20, 30 and 40, and the endmost elongated segment 50 form a “T” shaped handle 70.
The collapsible gun cleaning rod 1 according to the present invention has a number of advantages, which includes improving the rotor 66 or cylindrical rotor 66′ attached to the end of inextensible strand connector 2, providing the first elongated section 10 with the external support thread 11 and an enlarged portion 12, utilizing a stopping ring 67 and grooves 68 of the tubular elongated support 60 dispose within the opening slot 71 and providing a pair of elastic arms 72 and internal stoppers 73 and 74.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
