Definitions

• This invention relates to a spinning reel for fishing.
• a spinning reel of the type having a spool assembly including a spool shaft which reciprocates in an axial direction on rotation of a handle, the spool being mounted on a first axial end of a spool shaft, a drive mechanism being provided towards a second axial end of the spool shaft, opposite from the first axial end, and a rotor which turns about the spool for winding line onto the spool.
• fishing line is wound onto the spool by means of the rotor which turns about the axis of the spool shaft and describes a circle extending around the spool, carrying fishing line around the spool, for winding the line onto the spool.
• the speed at which line is wound onto the spool depends on the gearing of the reel and the speed at which the handle is turned. In some circumstances, it is desirable to have a faster winding speed than normal. It is known to provide two speed winding on existing spinning reels, however the mechanisms used for this involve complex gearing arrangements which are expensive to manufacture.
• the present invention seeks to provide a simpler mechanism which allows higher and lower speed winding but which is compact and easy and cheap to manufacture.
• a spinning reel for fishing comprising: a spool shaft, reciprocable in an axial direction during rotation of a handle shaft, a spool being mounted on the spool shaft at a first axial end of the spool shaft; a rotor for winding line onto the spool; means, operatively connected to the handle shaft for turning the rotor relative to the body of the spinning reel about the spool and spool shaft, for winding line onto the spool, characterised in that the spinning reel also includes means for selectively rotating the spool shaft about its central axis relative to the body of the spinning reel which can be optionally selected to increase the speed of rotation of the rotor relative to the spool.
• the means for turning the rotor about the spool shaft includes a bevel gear or other gear adapted to convert rotational movement in one axis to rotational movement in perpendicular axis, such as a spiral gear.
• the (first) bevel gear may be mounted about the spool shaft and a second bevel gear rotating about an axis perpendicular to the spool shaft may be provided which meshes with the first bevel gear.
• the first bevel gear is connected to the rotor and rotation of the first bevel gear about and relative to the spool shaft causes the rotor to turn about the spool.
• the second bevel gear is typically rotated about its axis by a pinion gear meshing with a spur gear rotated by a shaft connected to the handle.
• the spinning reel includes a third bevel gear mounted about the spool whose teeth oppose the teeth of the first bevel gear and which meshes with the second bevel gear so that the first and third bevel gears "sandwich" the second bevel gear and rotate in opposite directions about the spool shaft.
• first and third bevel gears will have the same number of teeth although the numbers of teeth can differ by small amounts (say by one or two teeth). Both first and third bevel gears may rotate relative to the shaft and move along the spool shaft.
• the reel may also include a clutch which is movable along the spool shaft between first position where it is engaged with the casing, or body of the spinning reel, a second position where it engages the third bevel gear, or a position where it does not engage the body or the bevel gear so that the spool rotates freely.
• the clutch is constrained so that it cannot rotate relative to the spool shaft.
• a highly preferred and novel feature of the invention is the use of a worm shaft and pin to drive the main shaft directly backwards and forwards in the direction of its longitudinal axis to reciprocate the spool backwards and forwards.
• Existing types of worm drive used in fishing reels include an arrangement where a separate worm shaft is set in the spool of the fishing reel, the worm shaft encircling the main shaft with the pin set in the rotor to drive the spool and reciprocate the spool along the longitudinal axis of the main shaft.
• a separate worm shaft is provided which is disposed parallel to the main shaft which is connected to the worm via a block which reciprocates up and down the worm shaft and thus causes the shaft and spool to reciprocate.
• the spool itself is fixed, and only the line guide which winds line onto the spool is oscillated by means of a worm shaft parallel to the axis of the spool.
• a spinning reel for fishing comprising: a main spool shaft, reciprocable in an axial direction during rotation of a handle shaft, a spool being mounted on the main spool shaft at a first axial end of the spool shaft: a pinion, rotatable during the rotation of the handle, for turning a rotor for winding line onto the spool: means, operatively connected to the handle shaft for turning the rotor relative to the body of the spinning reel about the spool and spool shaft, for winding line onto the spool, characterised in that the main spool shaft defines a worm shaft, the spool is fixed relative to the main spool shaft in use. and a pin co-operates with the worm shaft for driving and reciprocating the worm shaft, and hence
• the spool shaft is generally cylindrical and defines at least one groove which extends part way along the longitudinal extent of the shaft.
• the clutch is preferably generally annular and defines an inwardly extending protrusion shaped and configured to locate in the grooves when the clutch is mounted on the spool. More than one groove could be provided.
• One side of the clutch may define teeth adopted to engage with corresponding teeth on the reverse side of the third bevel gear.
• the other side of the clutch may also define teeth which are adapted to engage in a corresponding slot in the body or casing of the spinning reel.
• the clutch may define a friction plate which engages with a similar friction plate on the reverse side of the bevel gear.
• the amount of slip between the plates can be varied by adjusting the force pushing the friction plates together, in this manner the winding speed can be varied over a wide range depending on the amount of slip between the plates.
• a suitable switch or lever may be provided for moving the clutch.
• the switch or lever may be operated electromagnetically by a solenoid, or the like.
• control of the clutch is carried out remotely by means of a cable control mechanism whose lever or switch is located on the rod or handle of the fishing rod assembly which includes the spinning reel.
• the control cable may be of the standard type used to operate bicycle brakes and the like and comprising a fairly stiff wire disposed in a flexible tube. Of course this type of control means could be used to control other switches on fishing reels.
• a control system for a fishing reel assembly including a fishing reel and a fishing rod
• the control system comprising a switch, lever or the like disposed on the rod of the fishing rod assembly, preferably disposed on the handle of that rod, and a control cable operatively connecting that switch or lever to a switchable mechanism of the fishing reel to enable control of a feature of the fishing reel remotely from the fishing rod

• Figure 1 shows a schematic exploded view of a spinning reel for fishing, generally indicated at 10.
• the spinning reel includes a spool 12 on which fishing line is wound, the spool being mounted at the distal end 13 of the spinning reel, on a spool shaft 14. by means of a front tension drag mechanism generally indicated at 16. mounted on a screw thread 18 provided at the distal end 13 of the spool shaft 14.
• a rear drag assembly is also provided at the proximal end 20 of the spinning reel which assembly is standard in the art and is not shown in detail.
• the rear drag assembly is adjusted by knob 22.
• a large spur gear 24 is mounted on shaft 26 which is turned by a handle of the spinning reel which handle is fixed to the shaft to turn the same but which, to simplify the drawings is not illustrated.
• Spur gear 24 meshes with pinion gear 28 which is formed on a reverse (i.e. non-toothed) side of a bevel gear 30. Bevel gear 30 is thus rotated at an angular speed of rotation in direction B greater than the speed at which the handle is turned in direction A.
• the bevel gear 30 meshes with bevel gears 32 and 34 and rotates them in opposite directions at speeds ⁇ l and ⁇ 2 as indicated in Figure 1.
• bevel gears 32 and 34 are the same size and configuration, hence the gears rotate at the same angular speed but in opposite rotational senses.
• the sizes of the gears and/or the numbers of teeth may differ by one or two teeth.
• a rotor assembly 36 is mounted to bevel gear 34 and hence rotates at the same angular speed relative to the body of the spinning reel as does gear 34.
• Bevel gear 34 is integral with a reciprocating mechanism which causes the spool shaft to oscillate in the direction C-C.
• a reciprocating mechanism which causes the spool shaft to oscillate in the direction C-C.
• the system uses a worm shaft 15a formed directly on the main spool shaft 14 and a pin 15b to drive the spool shaft 14.
• Conventional spool reciprocation systems referred to in the introduction to this application are awkward to use in conjunction with the bevel gears of the present invention although they could be used.
• the present system uses the spool shaft 14 directly as the worm shaft and the pin is inside the bevel gear. This feature of having the reciprocation mechanism actually formed on the shaft enables the reel to be more compact.
• a clutch 38 is mounted on spool shaft 14 and is movable along the shaft 14, controlled by a suitable mechanism, such as a lever, not illustrated in Figure 1.
• a suitable mechanism such as a lever, not illustrated in Figure 1.
• the cross section of the spool shaft defines two diametrically opposed slots or grooves 14a. 14b. which extend along the shaft from the proximal end 20 of the shaft towards the distal end. terminating between bevel gear 32 and bevel gear 34.
• the clutch 38 defines protrusions, not illustrated, which locate in the groove so the clutch cannot rotate about or relative to the spool shaft.
• the clutch also defines a circumferential groove 39 which extends around the centre of the body of the clutch 38.
• the reverse side 32B of the bevel gear 32 defines four arcuate teeth or protrusions 40 which are spaced apart on the circumference of a circle.
• Both sides 38A and 38B of the clutch also define similarly sized and configured sets of teeth 42 and 44 respectively such that when clutch 38 is moved towards the distal end of the spinning reel into contact with bevel gear 32 the teeth 40 and 42 mesh and the clutch and the bevel gear 32 rotate as one.
• Facing the opposite side 38B of the clutch is a generally cruciform slot 46 in the casing of or a body portion of the spinning reel.
• the slot is configured to receive teeth 44 so that when the clutch 38 is moved towards the proximal end of the spinning reel teeth 44 engage in slot 46 and the clutch cannot rotate with respect to the body of the spinning reel.
• the spool shaft 14 In use if the clutch 38 is engaged with the spinning reel body 46 the spool shaft 14 is prevented from rotating and merely reciprocates backwards and forwards relative to the spinning reel body, handle etc.. in the direction C - C.
• the rotor to which in use the fishing line is attached rotates at speed ⁇ 2.
• the main shaft 14 and spool 12 do not turn hence the net speed at which line is fed onto the reel is merely ⁇ 2.
• the rotor is able to wind line onto the reel at much greater speed: if the bevel gears 32 and 34 are the same size the speed will be doubled.
• FIGS 2 to 6 show partly exploded views, of various options for mechanisms for controlling the clutch.
• Components of the spinning reel which are same as those shown in Figure 1. bear the same reference numerals.
• the clutch is normally biased, usually by means of springs and levers in a position intermediate bevel gear 32 and casing 46 in a "free spool" condition.
• one end 52 of a lever 50 defines a slot 54 between two flexible arms 52 A. B which engage in the circumferential groove 39 extending around the circumference of the centre of the clutch 38.
• the flexible arms act as leaf springs and continuously urge the teeth of the clutch 38 into mating contact with the casing or gear 32 to prevent fret (ridge) to fret mating of the teeth: if the ridges of the teeth do contact each other, as soon as the clutch and gear have rotated a sufficient distance relative to each other to inter-engage the arms will cause the teeth to interlock.
• the centre of the lever defines a pivot pin 55.
• One end 55 A of the pivot pin is cylindrical and is mounted in the body/casing of the spinning reel.
• the other end 55B of the pivot defines two flats 57.
• the flats acts to retain the lever in one of two stable positions corresponding to the clutch being engaged with the casing or the bevel gear 32 respectively, and the other, or handle end. 56 of the lever is used to pivot the one end 52 of the lever to move the clutch to cause the clutch to engage either the bevel gear 32 or the slot 46.
• the mechanism tends to have a definite "flip" action in changing the positions over which alerts the user that the desired changeover in the position of the lever has been initiated.
• FIG 3 a plate 60 having a circular cut out portion 62 engages in groove 39 and is moved by switch assembly 64 which can be moved parallel to the axis of the spool shaft 14. in the direction C-C.
• Figure 3a is a cross- sectional view through the switch assembly which shows the embodiment in more detail.
• An elongate slot is defined in the casing.
• a rod extends through the slot perpendicular to the casing and is fixed to a switch button 63.
• a spring plate 61 which defines a clip 65 or protrusion at either end holds the switch at positions at either end of the slot by means of channels 65a in the casing which receive the clips.
• At the end of the rod distal from the switch there are two springs 66a and 66b which act to smooth the operation of the clutch.
• the clutch's teeth are not able to engage with the teeth of the bevel gear.
• the spring plate 61 will hold the button 63 at the right by the effect of the clip 65 engaging in the channel 65a.
• the teeth of the clutch 38 are jammed against the teeth of the bevel gear 32 as illustrated in Figure 3a
• the clutch cannot properly engage with the engage with the bevel gear 32.
• Spring 66b is then compressed. Once the reel is operated by turning its handle, a relative displacement will occur between the clutch 38 and the gear 32. the teeth will be aligned and the spring 66b is then able to force the clutch 38 to move into the engaging position.
• Springs 66a and 66b act as a buffer and thus enable smooth and reliable clutch operation.
• one end 70 of a lever 72 defines a slot between two flexible arms 72A. B which engages in the circumferential groove 39 of the clutch 38.
• the lever defines a pivot 74 which is mounted in the body/case of the spinning reel.
• a handle 76 is fixed to the axis of the pivot pin so that turning the handle causes the level to pivot to the clutch with the body of the spinning reel or the bevel gear 32 as appropriate.
• a spring 78 biases the lever to retain the clutch in one of two stable positions corresponding to the clutch being engaged with the casing or bevel gear 32. respectively. By holding the handle 76 an angler may prevent the clutch teeth from being engaged with either the casing or the bevel gear 32 thus the reel is in a "free spool" condition.
• Flexible element/arm 72A performs the same function as springs 66a, 66b of Figure 3, in engaging the clutch and gear 32 where they do not initially mesh.
• a slot 100 for engaging in the groove 39 in the clutch is defined in a plate 102 which is mounted perpendicular to a further plate 104 which plate is slidable in direction C-C.
• a rod 106 extends from plate 104 and into a slot 107 in a lever arm 108.
• Plate 104 is biased by means of a spring 110 which acts as a buffer in a similar manner to springs 66a and 66b.
• the lever arm 108 is biased by means of a further spring 112 which tends to hold the clutch in one of two stable positions corresponding to the clutch being engaged with the casing or bevel gear 32, respectively.
• Rotation of handle 114 mounted about shaft 26 causes the clutch to move to engage either slot 46 or bevel gear 32. as appropriate.
• the provision of the handle 114 around the main handle shaft provides ease of access to speed changes.
• Figure 5a shows a similar view to Figure 5 illustrating the location of handle 114 in relation to the casing 115 and the reel winding handle 116.
• Figure 5b illustrates an embodiment in which the switch is moved electromagnetically by a solenoid 117 and ferromagnetic rod 118 on which a plate 119 engaging the groove 39 in the clutch is mounted. The rod is able to move along its longitudinal axis.
• a control system 120 operated by a switch, or possibly a computer, reverses the current through the solenoid and hence moves the rod and plate to the left or right.
• the solenoid 117 also acts as a buffer.
• Figure 6 shows a similar arrangement to Figure 4 except that the lever handle 120 is generally in the shape of an inverted J and projects upwards towards the back of the spinning reel. Anglers are used to having switches and controls located at the rear of the reel body/casing and the location of the switch there is preferred by some.
• Figures 7 and 8 show embodiments which have more substantial variations to the mechanism of the device and. in particular a different design of clutch plate.
• the clutch 138a. 138b engages with bevel gear 132 by friction only rather than by means of meshing teeth.

• the reverse side 132A of the bevel gear engages with surface 138 A. not shown, of clutch both of which are coated with materials which have a high coefficient of friction. In these embodiments the clutch is normally biased to the "slower" position where the spool is not turned.
• a plate-like lever 140 is pivoted to the casing of the spinning reel about axis 142. As oriented in Figure 7. when upper end 149 of the plate rotates in a clockwise direction D this causes clutch 138 to engage with bevel gear 132 and at the same time disengage from slot 148 which in turn causes the spool to rotate in the opposite sense to the rotor such that the relative speed of rotation is again ⁇ l + ⁇ 2.
• lever 140 moves in the anticlockwise direction E a slot 148 in the lever engages with a cross shaped protrusion defined in a clutch part 138b. This prevents the spool shaft from rotating relative to the casing/body of the spinning reel.
• Lever 140 is moved by a mechanism including a further lever 150, one end of which is attached to the upper end 149 of lever 140. the other end of which 154 is connected to a cable control mechanism 156.
