Description:Technical field of the inventionThe present invention relates to a fishing rod, especially fit for fly-fishing, comprising an elongated, thin and flexible body – referred to as the “blank” – removably installable within a handle assembly comprising at least one handle, and equipped with a reel for a fishing line, attached to the rod through a reel seat permanently affixed to the handle assembly.Background of the inventionThe basic fishing rod and reel have been known and used by sport anglers for a considerable period of time.A conventional sport fishing rod and reel setup consists of an elongated, thin and flexible body, often referred to as the “blank”, equipped with a gripping device comprising at least one handle, attached to the rod at the rear end of the rod, a reel with a fishing line attached to the rod at the rear end of the rod, and a fishing lure or bait attached to the end of the fishing line. Guide rings may be affixed to the blank at certain intervals along the blank, and the fishing line is threaded through the guide rings between the reel and the tip of the rod.As fishing rods tend to be long, commonly ranging from 2m to 4m, they are usually divided into shorter, more convenient sections that the angler assembles prior to fishing.Different rods, reels, fishing lines, lures and baits have been developed over the years in order to optimize the ability to catch different species of fish under different conditions. Each kind of angling method requires a specialized technique for casting and presenting the lure.Casting with a fishing rod, and a fly-fishing rod in particular, is all about managing the casting technique. Fly-fishing is an angling method that uses a light-weight lure—called an artificial fly— to catch fish. The light weight of the artificial fly requires casting techniques significantly different from other forms of casting. Unlike other casting methods, flyfishing can be thought of as a method of casting line rather than lure. Non-flyfishing methods rely on a lure's weight to pull line from the reel during the forward motion of a cast. By design, a fly is too light to be cast, and thus simply follows the unfurling of a properly cast fly line, which is heavier and tapered and therefore more castable than lines used in other types of fishing. For the angler it is of importance to "present" the fly as far out from the rod as possible. This requires a good casting technique, using a fishing rod with optimal qualities.Fly-fishing rods come in different sizes, usually denoted as the “weight” of the rod. The fly-fishing rod weight refers to the overall strength or size of the rod. Generally, the smaller the number, the lighter and weaker the rod is. Conversely, the larger the weight, the stronger and heavier the rod is.For the fly-fishing angler, the choice of rod weight depends on several factors, such as the size of the target fish, the size of the fly, the weight of the fishing line, weather conditions, the characteristics of the vegetation along the waterfront, and conditions relative to the water, such as whether it is still or running, flat or wavy.As the above-mentioned factors may change frequently, it is often necessary for the angler to bring several fly-fishing rods with different weights for a single fishing trip.Accordingly, a need will be seen for a system of interchangeable fly-fishing blanks with different weights using a common handle and reel seat.Furthermore, the rods of different weight will generally have varying total lengths, and the tapering design of the blanks means that the different blanks will have varying diameters at their butt ends. Accordingly, a need will be seen for a system that can accommodate interchangeable blanks of varying diameters, and provide a means of securing them tightly.Generally, the fly-fishing rods with lower weight are used for single-handed casting, while the larger weight rods are used for two-handed casting. For single-handed casting, the rods are equipped with a gripping device consisting of a single handle, while the two-handed rods are equipped with a gripping device consisting of two handles. Some fly-fishing rods are equipped with a detachable second handle, letting the angler choose between one-handed and two-handed casting by their own preference.Accordingly, a need will be seen for a handle assembly that can accommodate a detachable second handle for use with the higher weight blanks.In accordance with the present invention, the above-mentioned needs are accomplished by the introduction of a fitting sleeve permanently affixed to the butt end of the lower section of the blank.The fitting sleeve has a mostly cylindrical shape, and is aligned concentrically along the butt end of the blank. The handle assembly has a mostly cylindrical cavity that is aligned axially along the handle, with an aperture of said cavity in the butt end the handle assembly. The shape and size of the cavity in the handle assembly corresponds with the outer surface of the fitting sleeve, in such a way that the cavity fits closely around the fitting sleeve when the blank is entered into the handle assembly. Furthermore, the handle assembly has an axial passage through the entirety of the handle assembly, allowing the part of the blank that protrudes from the fitting sleeve to pass through the handle assembly.The fitting sleeve is permanently affixed to the butt end of the lower section of the blank using glue or other commonly known means. When several blanks are equipped with fitting sleeves, blanks of varying diameters can be interchangeably and securely installed in the universal handle assembly. While the fitting sleeves can be attached to blanks of varying outer shapes and diameters, the fitting sleeves themselves have a uniform outer surface and geometry, allowing the interchangeable installation of different blanks in a universal handle assembly.The lower section of the blank may be free from any permanently affixed guide rings, allowing the lower section of the blank with the fitting sleeve to be entered into the handle assembly from the butt end of the handle assembly.The handle assembly may be equipped with a locking device on the butt end of the handle assembly, which can be locked in place with a well-known means such as a threaded cap nut or a latch. When locked in place, the locking device secures the blank inside the handle assembly.Moreover, both ends of the fitting sleeve may include conical surfaces that interlock with matching conical surfaces within the handle assembly. The conical surfaces ensure that the fitting sleeve is placed in a tight grip, preventing any axial or radial movements of the fitting sleeve relative to the handle assembly.By entering the blank with the fitting sleeve from the butt end of the handle assembly and locking it in place with a locking device that pushes the fitting sleeve axially forward, a constant axial force is applied between the forward-facing conical surface on the forwardmost end of the fitting sleeve and the rearward-facing conical surface in the forwardmost end of the cavity in the handle assembly.The locking device includes a forward-facing conical surface that interacts with a matching, rearward-facing conical surface on the butt end on the fitting sleeve, consequently creating constant and simultaneous axial forces on the conical surfaces in both ends of the fitting sleeve, and thus placing the fitting sleeve in an immoveable grip. Furthermore, the interlocking of conical surfaces in the handle assembly and on the fitting sleeve ensure the concentrical alignment of the blank within the handle assembly when an axial force is applied between the fitting sleeve and the handle assembly.In one embodiment of the invention, the butt end of the handle assembly is equipped with exterior threads, and the locking device is shaped as a fastening cap with internal threads that can be screwed onto the exterior threads on the handle assembly. The inside of the fastening cap is equipped with a forward-facing conical surface that interacts with a matching, rearward-facing conical surface on the butt end of the fitting sleeve.Furthermore, the fastening cap can be replaced with a prolonged fastening cap that also comprises a second handle for the angler, thus allowing the angler to use the rod with a two-handled grip by their own preference.A discussion of the related art of which the present inventor is aware, and its differences and distinctions from the present invention, is provided below.U.S. Patent No.6,115,955 issued on Sep. 12, 2000 to Leroy Sledge, titled “INTERCHANGEABLE SYSTEM FOR FISHING RODS” describes a fishing rod assembly with interchangeable handle components that permits different reels, different counterweights or counterweight amounts, and even different rod blank assemblies, to be assembled and used interchangeably with one another for different types of fishing. The handle includes an axial passage for a blank to be removably installed. The passage fits tightly around the blank, and consequently does not accommodate blanks with varying diameters. Sledge makes no mention of a fitting sleeve or other means to accommodate blanks with varying diameters. In the Sledge invention, the blank is entered from the front of the handle assembly. US 2021360909 A1 describes a modular fishing rod system allowing the end user to easily and securely change one or more of the handle portion and rod blank. The system includes a rod blank, rod sleeve assembly and a slide-on handle assembly.Summary of the inventionA principal object of the present invention is to provide an improved fishing rod and handle assembly, with the handle assembly able to interchangeably accommodate different fishing rod blanks.A further object of the invention is to provide an improved fishing rod and handle assembly where the angler can change fishing rod blanks quickly and conveniently.Another object of the invention is to is to provide an improved fishing rod and handle assembly, with the handle assembly being able to accommodate fishing rod blanks of various diameters.Yet another object of the invention is to provide an improved fishing rod and handle assembly, with the handle assembly being able to secure the fishing rod blank in a tight and immoveable grip.Another additional object of the invention is to ensure the concentrical alignment of the fishing rod blank within the handle assembly.Another object of the invention is to provide an improved fishing rod and handle assembly, where the handle assembly can be equipped with a second handle for a two-handed grip, as desired by the angler.Yet another additional object of the invention is to provide an improved fishing rod and handle assembly, with the optional second handle providing means for locking the blank inside the handle assembly. Yet another object of the invention is to provide an improved fishing rod and handle assembly, where the use of a common, universal handle assembly provides an inexpensive option for the angler compared to buying several complete rod and handle assemblies.Yet another additional object of the invention is to provide an improved fishing rod and handle assembly, where the production of a common, universal handle assembly consumes less materials and resources, and creates a smaller environmental impact, compared to producing several complete rod and handle assemblies.According to the invention, the objects are achieved with a fishing rod as further defined in the characterizing part of claim 1, read in connection with the preamble of the claim.Various embodiments of the invention are defined in the dependent claims.Brief summary of the drawingsOne embodiment of the invention shall in the following be described more closely with references to the accompanying drawings, where:Figure 1 shows a view of the rear part of a fishing rod, comprising a handle assembly with a fishing reel, an interchangeably installable rod blank, and a locking device in the shape of a fastening cap according to the invention;Figure 2 shows a view of the rear part of a fishing rod, comprising a handle assembly with a fishing reel, an interchangeably installable rod blank, and a prolonged fastening cap that embodies a second handle for a two-handed grip according to the invention; Figure 3 shows a disassembled view of the rear part of a fishing rod according to the invention, with a handle assembly, a rod blank with an affixed fitting sleeve, a fastening cap and also a prolonged fastening cap that embodies an optional second handle for a two-handed grip;Figure 4 shows a sectional view of the rear part of a fishing rod, comprising a handle assembly, an interchangeably installable rod blank with an affixed fitting sleeve and a fastening cap according to the invention;Figure 5 shows a sectional view of the rear part of a fishing rod, comprising a handle assembly, an interchangeably installable rod blank with an affixed fitting sleeve, and a prolonged fastening cap that embodies a second handle for a two-handed grip according to the invention;Figure 6 shows a sectional view of the rear part of three different rod blanks, each equipped with an affixed fitting sleeve according to the invention, where the Figure shows how blanks of different diameters may be equipped with fittings sleeves that have a common outer diameter, and also shows how a fitting sleeve may be split in two parts in order to reduce the weight of the construction.Detailed description in connection to the drawingsFigure 1 shows a view of the rear part of a fishing rod, including an oblong, thin and elastic body commonly referred to as the rod blank 10, equipped with a fitting sleeve 11 (not shown) installed in a handle assembly 12 according to the invention. The blank 10 with the fitting sleeve 11 is locked inside the handle assembly 12 with a locking device in the shape of a fastening cap 13 attached to the butt end of the handle assembly 12. The fastening cap 13 is attached to the handle assembly 12 by means of conventional fasteners, well known to a person skilled in the art, such as external threading 17 on the butt end of the handle assembly and matching internal threading 20 (not shown) on the fastening cap. The fishing rod is further equipped with a fishing reel 15 that contains a line (not shown) rolled up on the reel 15. The fishing reel 15 is attached to the handle assembly 12 by means of conventional fasteners, well known to a person skilled in the art, such as axially movable reel seat collars 16 and a permanent seat or receptable 19 on the handle assembly 12, between which the conventional shoes or levers on the base of a conventional fishing reel 15 are sandwiched when the collars 16 are moved forward axially along the handle assembly 12.It should be mentioned that the axially movable collars 16 and the fastening cap 13 could be connected to the handle assembly 12 by means of a common section of external threading 17 on the handle assembly 12.It should also be mentioned that the fishing line (not shown) may be equipped with backing,shooting line, shooting head and leader. Since none of these items form part of the invention, and since such items are well known to a person skilled in the art, these are not shown and will not be described. Moreover, it should be mentioned that the fishing rod is further equipped with line guides, through which the line runs. These are not a part of the invention either, and will thus not be described any further.Figure 2 shows a view of the rear part of a fishing rod, including a rod blank 10, equipped with a fitting sleeve 11 (not shown) installed in a handle assembly 12 according to the invention. The blank 10 with the fitting sleeve 11 is locked inside the handle assembly 12 with locking device in the shape of a prolonged fastening cap 14 that embodies a second handle for a two-handed grip, attached to the butt end of the handle assembly 12. The prolonged fastening cap 14 is attached to the handle assembly 12 by means of conventional fasteners, well known to a person skilled in the art, such as external threading 17 on the butt end of the handle assembly and matching internal threading 20 (not shown) on the fastening cap.Figure 3 shows a disassembled view of the rear part of a fishing rod with a handle assembly 12, a rod blank 10 with an affixed fitting sleeve 11, a fastening cap 13 and also a prolonged fastening cap 14 that embodies an optional second handle for a two-handed grip according to the invention.The handle assembly 12 includes a front handle 18, a permanent seat or receptable 19 for the front shoe or lever on the base of a conventional fishing reel and axially movable reel seat collars 16 attached to a section with external threading 17.The butt end of the handle assembly has an aperture 21 that allows the rod blank 10 with the fitting sleeve 11 to be inserted into the handle assembly 12 from the butt end of the handle assembly 12.The rod blank 10 is equipped with a permanently affixed fitting sleeve 11. The forwardmost end of the fitting sleeve 11 has a forward-facing conical surface 22 that interlocks with a matching, rearward-facing conical surface 24 (not shown) in the forwardmost end of the cavity inside the handle assembly 12, when the f itting sleeve 11 is pushed forward by the fastening cap 13 or the prolonged fastening cap 14. Furthermore, the butt end of the fitting sleeve 11 has a rearward-facing conical surface 23 that interlocks with a matching, forward-facing conical surface 25 (not shown) inside the fastening cap # or the prolonged fastening cap #.The simultaneous interlocking of the conical surfaces 22 and 24 in the forwardmost end of the fitting sleeve 11 and the conical surfaces 23 and 25 in the butt end of the fitting sleeve 11 ensures that the rod blank 10 with the fitting sleeve 11 is concentrically aligned and immovably locked inside the handle assembly 12.The fastening cap 13 and the prolonged fastening cap 14 both have internal threading 20 that allows interchangeable attachment on the external threading 17 on the handle assembly 12. The prolonged fastening cap 14 provides an optional second handle for a two-handed grip. Figure 4 shows a sectional view of the rear part of a fishing rod with a handle assembly 12, a rod blank 10 with an affixed fitting sleeve 11 and a fastening cap 13 according to the invention.The handle assembly 12 has a mostly cylindrical cavity that is aligned axially along the handle. The shape and size of the cavity in the handle assembly 12 corresponds with the outer surface of the fitting sleeve 11, in such a way that the cavity fits closely around the fitting sleeve 11 when the blank 10 with the affixed fitting sleeve 11 is entered into the handle assembly 12.The part of the blank 10 that protrudes from the affixed fitting sleeve 11 passes freely through an axial passage 26 through the entirety of the handle assembly 12. It should be noted that the diameter of the axial passage 26 is larger than the largest diameter of any rod blank 10 to be installed in the handle assembly.The rod blank 10 is equipped with a permanently affixed fitting sleeve 11. The fitting sleeve 11 has a mostly cylindrical shape, and is aligned concentrically along the butt end of the blank 10. The forwardmost end of the fitting sleeve 11 has a forwardfacing conical surface 22 that interlocks with a matching, rearward-facing conical surface 24 in the forwardmost end of the cavity inside the handle assembly 12, when axial force is applied by the forward movement of the fastening cap 13.Furthermore, the butt end of the fitting sleeve 11 has a rearward-facing conical surface 23 that interlocks with a matching, forward-facing conical surface 25 inside the fastening cap 13.The simultaneous interlocking of the conical surfaces 22 and 24 in the forwardmost end of the fitting sleeve 11 and the conical surfaces 23 and 25 in the butt end of the fitting sleeve 11 ensures that the rod blank 10 with the fitting sleeve 11 is concentrically aligned and immovably locked inside the handle assembly 12. The gripping surface 27 of the handle assembly 12 may be covered with different materials intended to give the handle optimum gripping qualities. The materials may be cork laminate, soft rubber, rubber foam or textile. These materials have unique qualities and are considered used to achieve a firmer and more comfortable grip under all conditions (cold, warm, wet, dry).The handle assembly has a seat or receptable 19 for the front shoe of a conventional fishing reel 15 (not shown), and axially movable reel seat collars 16 for the rear shoe of the same fishing reel 15 (not shown). The axially movable collars 16 are moveable along the handle assembly 12 by means of an externally threaded surface 17 on the handle assembly 12.Figure 5 shows a sectional view of the rear part of a fishing rod with a handle assembly 12, a rod blank 10 with an affixed fitting sleeve 11 and a prolonged fastening cap 14 that embodies a second handle for a two-handed grip according to the invention.The handle assembly 12 has a mostly cylindrical cavity that is aligned axially along the handle. The shape and size of the cavity in the handle assembly 12 corresponds with the outer surface of the fitting sleeve 11, in such a way that the cavity fits closely around the fitting sleeve 11 when the blank 10 with the affixed fitting sleeve 11 is entered into the handle assembly 12.The part of the blank 10 that protrudes from the af fixed fitting sleeve 11 passes freely through an axial passage 26 through the entirety of the handle assembly 12. It should be noted that the diameter of the axial passage 26 is larger than the largest diameter of any rod blank 10 to be installed in the handle assembly.The rod blank 10 is equipped with a permanently affixed fitting sleeve 11. The fitting sleeve 11 has a mostly cylindrical shape, and is aligned concentrically along the butt end of the blank 10. The forwardmost end of the fitting sleeve 11 has a forwardfacing conical surface 22 that interlocks with a matching, rearward-facing conical surface 24 in the forwardmost end of the cavity inside the handle assembly 12, when axial force is applied by the forward movement of the prolonged fastening cap 14.Furthermore, the butt end of the fitting sleeve 11 has a rearward-facing conical surface 23 that interlocks with a matching, forward-facing conical surface 25 inside the prolonged fastening cap 14.The simultaneous interlocking of the conical surfaces 22 and 24 in the forwardmost end of the fitting sleeve 11 and the conical surfaces 23 and 25 in the butt end of the fitting sleeve 11 ensures that the rod blank 10 with the fitting sleeve 11 is concentrically aligned and immovably locked inside the handle assembly 12.The gripping surface 27 of the handle assembly 12 may be covered with different materials intended to give the handle optimum gripping qualities. The materials may be cork laminate, soft rubber, rubber foam or textile. These materials have unique qualities and are considered used to achieve a firmer and more comfortable grip under all conditions (cold, warm, wet, dry).Furthermore, the gripping surface 28 of the prolonged fastening cap 14 may be covered with different materials intended to give the handle optimum gripping qualities.The handle assembly has a seat or receptable 19 for the front shoe of a conventional fishing reel 15 (not shown), and axially movable reel seat collars 16 for the rear shoe of the same fishing reel 15 (not shown). The axially movable collars 16 are moveable along the handle assembly 12 by means of an externally threaded surface 17 on the handle assembly 12.Figure 6 shows a sectional view of the rear part of three different rod blanks 101, 102 and 103, each equipped with affixed fitting sleeves 111, 112, 113 and 114 according to the invention. The rod blank 101 has a larger diameter, while the rod blank 102 has a smaller diameter. The fitting sleeves 111 and 112 have identical outer diameters, and identical, forward-facing conical surfaces 221 and 222 in the forwardmost end and identical, rearward-facing conical surfaces 231 and 232 in the butt end.The rod blank 103 is equipped with a fitting sleeve that is spilt into a front part 113 and a rear part 114. The fitting sleeve parts 113 and 114 are affixed to the rod blank 103 is such a position that the forward-facing conical surface 223 and the rearwardfacing conical surface 233 are identically shaped and identically placed compared to the conical surfaces 22 and 23 on the fitting sleeve 11 (not shown).In the embodiments shown in the Figure, the fitting sleeves 111, 112, 113 and 114 are permanently affixed to the blanks 101, 102 and 103 using glue 29. Is should be mentioned that the fitting sleeves 111, 112, 113 and 114 may be permanently affixed to their respective blanks 101, 102 and 103 by other conventional means, well known to a person skilled in the art, such as set screws, or the molding or casting of a material onto the blank.Furthermore, it should be noted that the embodiment of the fitting sleeve in two separate parts 113 and 114 may be a means of reducing the weight of theconstruction.
