Abstract

The bush 11 comprises a body section 12 having, in sequence, a first sleeve section 15 whereby the bush can be located on a pole an intermediate section (17) extending from the end of the sleeve section opening into a cavity section 20 and a control member 25 retained in the cavity. The external shape of the control member 25 is at least in part complementing that the internal shape of the cavity, so that the control member can be rotated within the cavity. In use elastic cord c passes through the body section and control member so that any sideway pull on the cord causes the control member to rotate and presses the cord against the body section.

POLE FISHING ACCESSORY

This invention relates to a pole fishing accessory.

Pole fishing involves the use of a hollow pole (typically having an assembled length between 8 to 16 metres) with no external eyes and no reel. Line is attached to the pole either directly by way of a connector or using a length of elastic to whose outboard end the line is joined by a connector. The length of elastic is housed within the pole with its inboard end secured to the pole. The elastic acts as a shock absorber to loads transmitted along the line.

The length of a typical pole, the need for it to be portable and the loads to which it can be subjected result in the pole being manufactured in sections from light but strong materials (such as carbon fibre reinforced plastic or Kevlar). The sections are readily assembled and equipped for use and readily dis-assembled following use.

To ensure the smooth two-way passage of elastic stored in fishing pole sections into and out of the pole the outboard end of the pole is usually terminated with a hollow bush fabricated from a low friction polymer such as P.T.F.E. This material is of such low friction that that little additional restraint can be applied to the elastic in sliding in and out of the bush. In the course of fishing speed of use is dependent on the strength and elasticity of the chosen elastic. The elastic having passed out of the bush generally lies at an angle to the longitudinal axis of the pole.

According to a first aspect of the present invention there is provided an outboard bush for a fishing pole comprising: a body section with an inboard end and an outboard end, the body section having, in sequence, a first sleeve section whereby the bush can be located on a pole end; the first sleeve section opening into an intermediate section extending from the end of the sleeve section to an intermediate outlet where the intermediate section opens into a cavity section; the cavity section extending from the intermediate outlet c . . . . c.

.. to an outlet aperture in the outboard end of the body, the intermediate bore and the cavity being co-axial with a first longitudinal axis of the bush; the intermediate bore and the cavity in combination providing a path through the bush; the cavity being symmetrical in form about the first longitudinal axis; and a control member retained in the cavity with an external shape at least in part complementing that the internal shape of the cavity so that the control member can be rotated within the cavity; the control member having a working bore extending through it with a second longitudinal axis, the working bore having an inboard end and an outboard end; the control member having a first position within the cavity wherein the second longitudinal axis is coaxial with the first longitudinal axis of the intermediate section such that the inboard end of the working bore opens freely into the intermediate outlet; and the outboard end of the working bore is disposed symmetrically relative to, and opens freely into the outlet aperture; and as the control member rotates from the first position the angular alignment of the second longitudinal axis of the control member increases with respect to the first longitudinal axis of the bush then the size of a passage linking the intermediate bore and the working bore is progressively reduced.

According to a first preferred version of the first aspect of the present invention the first and second ends of the working bore differ in shape so that their interaction with intermediate outlet by way of a cord lying between the first or second end differ in effect.

According to a second aspect of the present invention there is provided a fishing pole equipped with an outboard bush according to the first aspect of the present invention.

The object of the following is to preferentially limit the availability of elastic by uncovering resistance within the contours of the bush.

. . e e 1 . . . An exemplary embodiment of the invention will now be described with reference to the accompanying drawings of longitudinal sections of a fishing pole bush of which: Figure 1 shows components in a first position; Figure 2 shows components of Figure in a second position; and Figure 3 shows bush in use with additional components.

The figures variously show an outboard bush 11 for a fishing pole comprising a body section 12 with an inboard end 13 and an outboard end 14. The bush 11 has a first longitudinal axis A1 and an hollow interior including a first sleeve section 15 by means of which the bush 11 is located on a pole end 16 (figure 3) the dimensions being such as to provide an interference fit. The first sleeve 15 opens into an intermediate section 17 extending from end 18 of the first sleeve section 15 to an intermediate outlet 19 where the intermediate section 17 opens into a cavity section 20. The cavity section 20 extends from the intermediate outlet 19 to aperture 21 in outboard end 14.

The intermediate section 17 and cavity section 20 are co-axial with first longitudinal axis A1 of the bush 11. The intermediate section 17 and the cavity section 20 in combination and in line provide a through path through the bush 11. In this case the cavity section 20 is symmetrical in form about the first longitudinal axis A1.

A control member 25 is retained in the cavity section 20 with an external shape at least in part complementing the internal shape of the cavity section 20 so that the control member 25 while retained in the cavity section 20 is able to freely rotate within it. The control member 25 has a working bore 26 with a second longitudinal axis A2. Internal diameter D of working bore 26 is of the same size as internal diameter D' of intermediate section 17. The working bore 26 has: a first end 28 terminating in a spigot 29 surrounded by an annulus 30 formed on the control member 25; and a second end 31 whose rim 31B is very slightly chamfered.

ccec see c ce c e e c ec ee c e e ee ccee c ace e ee c e cc ee e e The provision on control member 25 of first end 28 and second end 31 provides for two different performance characteristics as will be described briefly hereafter.

The bush 11 and the control member 25 are each moulded from a P.T.F.E. filled Acetal plastics material.

Figure 3 shows the bush 11 described in connection with Figures 1 and 2 in use with an elastic cord C whose inner end (to the right as viewed in Figure 3) is anchored to a an internal connection within pole P. The elastic cord C extends out of the bush (to the left and upwardly as shown in Figure 3) and is connected to an inner end of a fishing line whose outer end is attached to a conventional fishing hook and such other components as may be required.

It will be seen that with the cord drawn to the right as shown the axis C' of that part of the cord C lying outside the bush 12 is at an angle to axis A1 of the bush and to axis A2 of the conko1 member 25. As a result the sideways pull applied by the cord C to the pole 16 causes the control member 25 to twist within cavity 20 with the result that the spigot 29 of first end 28 of the control member 25 is pressed into contact with the cord C in the vicinity of intermediate outlet 19 and effectively prevents to a greater or lesser extent the ability of cord C within the pole 16 to pass out of the bush 11. As a result the length of cord extending through the control member 25 and lying outside the bush 11 is effectively the only resilient means governing movement of the attached line and hook.

The form of the spigot 29 with its curved edges means that the rate of application of any trapping action on the cord C lying between spigot 29 and outlet 19 is applied relatively slowly. This contrasts with the action of the first end 31 of the control member 25.

If the pole is now turned to cause the pole to be in line with the direction of the cord outside the bush 11 then the control member 25 is restored to an alignment in which eee e e e' e e a e ë ë e e e e e e e e e ee e e e e e its second longitudinal axis A2 is in line with first axis A1 of the bush 11 then working bore 26 aligns with intermediate section 17 to give a free run to elastic cord C into and out of the pole 16. This results in effectively the resilience of the whole length of the cord C acting on the attached fishing line and hook.

If required the trapping action of the control member 25 on the cord C in the vicinity of the outlet 19 can be changed by reversing the position of the working member 25 in the cavity 20 during assembly of the pole or subsequently so that it lies as shown in Figure 2 with second end 31 adjacent the outlet 19. In this case with the cord C in position and moving the pole so as to cause the cord C to draw at an angle to the first longitudinal axis A1 result in the rim 31B of the working member being driven into contact with the cord C in the vicinity of the outlet 19 with an immediate jamming effect. The change between first end 28 and second end 31 is readily undertaken by a user.

The choice of what size of bush 11 to use will depend on the size of cord C chosen which will in turn affect the bore size D, D' which would normally be chosen to be identical in size.
