It comprises an eccentric device (26) attached to the relocatable rod section (21) and a sleeve (20) surrounding the eccentric device (26) on the relocatable rod section. At least one of the two mutually axially relocatable elements can be turned about the longitudinal axis of the arrangement.

Description

Arrangement at telescopic rods, particularly the butt section of fishing rods.
The invention concerns an arrangement at telescopic rods in accordance with the introductory part of patent claim 1. An arrangement of this type is used for various purposes in which rods are being adjusted longitudinally. A particularly relevant purpose is for adjusting the butt section on fishing rods.
Background
Numerous rods need in certain ranges of use to be extended or shortened. It could be table legs, camera stands and similar, grips, for example for fishing rods, or rods which carry lamps or similar equipment.
In connection with fishing rods, the need for extendibility is related to the wish of flexible use. We have not found any fishing rods with an extendible or length adjustable butt section.
UK patent application No. 2032743 describes a telescopic mechanism, in which an extension rod is inserted into a tubular butt section of a fishing rod. The extension rod can be withdrawn and pushed in under influence of a friction element. This does not provide any stable or safe mechanism.
UK patent application No. 2131261 describes a telescopic member fastened in the butt section of a fishing rod by means of a deformable expansion sleeve which is expandable by a nucleus of a screw activated by turning the telescopic member. Neither this provides a satisfactory locking and rearrangement.
US patent 1,839,751 describes the use of a friction sleeve on an extension member on a butt section of a fishing rod, but this solution did not find any practical use.
From US patent 5,535,539 it is known to extend a butt section by using a joint pipe with an adapted length in a telescopic manner on a screw socket, which can be screwed to the end of a fishing rod. This provides to a certain degree a possibility of obtaining individual adjustment of the butt section, but no possibility of a fast extension.
Object The main objective of the invention is to create a telescopic mechanism for use with rods, which is simple to adjust in the longitudinal direction. A particular object is to create such a mechanism which is suitable for use on butt sections of fishing rods in order to make them extendable.
The relocatable rod section must, for use with fishing rods, fit in to a pipe opening of 6 - 7 millimetres, and sometimes less. The invention
The invention is stated in patent claim 1. A telescopic mechanism of this type can be used for many purposes. The invention is particularly suitable for use in connection with fishing rods, to optimize the design of these. The invention is particularly advantageous for telescopic rods having a small diameter, also down to 5 mm, where space is limited.
When used with fishing rods, the rods are substantially one-handed fly rods. It is possible to realize the invention with a massive carbon rod and a locking sleeve of plastics. The product has a very simple construction and a convenient one-handed operation by a small twisting for fixation in any position. The two main components of the product are easy to mount as long as the fishing rod is hollow, and has a sufficient cavity for the rod extender.
An extendable, lockable end cap on a one-handed fly rod is useful in a combat with a fish. The extension results in an amended momentum and the fishing reel and butt section is moved away from the body, and a three-point operation makes it easier to cope with the fish. Even with a big fish on the hook, one hand is free (the end rests on the belly, one hand keeps the rod upright) to operate the break and perform catching in or gripping of the fish.
The extension makes it possible to throw with both hands, when necessary. This enables even beginners to throw with a fly rod, and the fisher can control the distance between butt sections according to his arm length. It is also possible to vary between one-handed and two-handed operation, dependent of how tired the fisher is. Two-handed operation produces more power and smoother movements, which makes it possible to obtain a nice throw and good length in a short period of time.
More power enables the use of heavier fishing lines and larger flies, which is normal when fishing for larger fish. Two-handed function is also a basis for development of new throwing techniques such as speycast. This technique is traditionally connected to two-handed rods, and it is easy to learn and use speycast with a two-handed fly rod. The extendable end cap enables practising and use of all known casting techniques with one single rod. For that reason, it makes the one-handed rod more useable and more usable in all fishing disciplines, including newer techniques.
Some places the most frequently used rods are spool and jig rods. The invention also makes it possible to change between a short butt section which is out the way during cranking-in and during jigging and trolling from boat, which makes the reel to come closer to the body. But in the same time it can be used with a long butt section when making a throw.
Example The invention is described in further detail below with reference to the drawings, wherein Figure 1 shows an axial cross-section of one embodiment of the butt section end of a fishing rod with a telescopic mechanism in accordance with the invention,
Figure 2 shows a cross-section of a locking element with a single locking eccentricity, Figure 3 shows a cross-section of a locking element with a double locking eccentricity, whereas Figure 4 shows a perspective sketch of a locking element for use with the embodiment of Figure
3.
Figure 1 shows a fishing rod 11 having a butt section end 12. At the butt section end, the fishing rod 11 has a tubular end section HA with a sleeve-shaped grip handle 14 of a suitable material. The end section HA is provided with a tubular reel bracket 13. At the external end of the grip handle 14 there is an overlap between this and the tubular reel attachment 14. At this overlap 15 there is a ferrule 16 for a reel leg. The external end of the tubular reel bracket 13 exhibits threads 17 for a lock nut 18, which in combination with a collar or ferrule 19 ensure attachment for the reel leg. In some cases a double lock nut 18 is used.
A combined guide and locking sleeve 20 is inserted in the reel bracket 13. The guide and locking sleeve 20 is adhered to the reel attachment 13 and thus locked against twisting.
A relocatable rod 21 is inserted through the guide and locking sleeve 20, the relocatable rod having an internal guide sleeve and extension stopper 22 which slides internally in the tubular rod end 12 and having a cap 23 with a blunt point, which encapsulates the end of the reel attachment 13. Details of the guide and locking sleeve 20 and the relocatable rod 21 are shown in Figures 2-4. Figure 2 shows a cross-section through a guide and locking sleeve 20 with a single eccentric surface 24 which extends in a ramp shaped manner around the periphery from a radial notch 25. The notch can exhibit a radial dimension of 0.2-0.5 mm. The relocatable rod 21 has s similar eccentric surface 26 which extends around the periphery from a radial notch 27. When the notches 25 and 27 are contacting each other, the rod 21 can be moved axially through the guide and locking sleeve 20. Mutual twisting of the two parts produces a locking clamping effect between the two eccentric or ramp surfaces 24 and 26.
Figure 3 and 4 show an embodiment in accordance with double eccentric surfaces arranged symmetrically about the longitudinal axis.
When adjusting the telescopic mechanism in accordance with the invention, the end cap 23 is turned or twisted until the notches 25 and 27 contact each other. Then, the relocatable rod 21 is adjusted as desired before the end cap 23 is turned to lock the two eccentric surfaces.
The product is designed to be mounted on existing fishing rods or similar equipment. The telescopic function and mode of operation is simple and is based upon the principle of mutual twisting of two eccentric elements. The product is light weight, from about 15 to 25 grams dependent on the requirements to resistance to breaking. The invention can be adapted for use with telescopic mechanisms for other purposes than fishing rods. It may be photo and lamp stands, tables and chairs, ski poles, bicycle seats or measurement instruments.
