Description
- 1. Technical Field
- The present invention relates to spools, and in particular to spinning reel spools that reciprocate with respect to the reel unit.
- 2. Description of Related Art
- Typical spinning reels include a reel unit, a rotor, a spool, and a handle that is rotatively supported on the reel unit. The spinning reel spool, which reciprocates with respect to the reel unit, comprises: a bobbin trunk onto which fishing line is wound; a front flange disposed on the front end of, and having a larger diameter than, the bobbin trunk; and a skirt having a rear flange, provided on the rear of the bobbin trunk. The skirt rear flange is furnished either separately from or unitarily with the bobbin trunk. The front flange is fastened with a front-flange fastening member to the bobbin trunk.
- Among spools of this sort, ones in which the bobbin trunk is, for example, formed of synthetic resin and ones in which it is formed of an aluminum alloy sheet metal, which serves to lighten the spool overall, are known. Also, the front flange should maintain the relative strength of the spinning reel and improve the gliding of the fishing line. Therefore, some front flanges are formed by an element that is a different material, separate from the bobbin trunk.
- In the aforementioned conventional spools made from synthetic resin, the relative strength of the bobbin trunk is in general liable to deteriorate. The bobbin trunk relative strength in spools formed from sheet metal also is liable to deteriorate since the sheet thickness is made thin. Deterioration thus in the bobbin trunk relative strength, when for example strong pressing force is applied to the bobbin trunk by winding on fishing line, may end up deforming the bobbin trunk. When the bobbin trunk, in particular the front end of the bobbin trunk, is deformed this way, a gap is created between the bobbin trunk and the front flange, since the front flange is a separate element from the bobbin trunk. This risks fishing line getting jammed in the gap.
- Furthermore, in spools in which the skirt is furnished separately from the bobbin trunk, since the rear flange is separate from the bobbin trunk, a gap arises between the bobbin trunk and the rear flange, and there is the possibility that fishing line gets jammed in the gap.
- An object of the present invention is in spinning reel spools to make it unlikely that fishing line jams in between the bobbin trunk and the flange.
- According to a first aspect of the present invention, a spinning reel spool that can be shifted back and forth with respect to a reel unit, includes a tubular bobbin trunk for winding fishing line around its circumference, a flange attached to one end of the bobbin trunk, and a reinforcement provided on the same side of the bobbin trunk as the flange.
- In such a spool, a reinforcement is provided on the same side of the bobbin trunk as the flange, so that it is possible to prevent deformations of the bobbin trunk when a strong pressure is exerted on the end of the bobbin trunk. Consequently, a gap between the flange and the bobbin trunk is formed less easily, and it is possible to prevent the fishing line from getting tuck in such a gap.
- According to a second aspect of the present invention, in a spool as in the first aspect, the flange is a front flange attached to a front end of the bobbin trunk. With this configuration, it is possible to prevent the fishing line from getting jammed between the front flange and the bobbin trunk.
- According to a third aspect of the present invention, a spool as in the first or second aspect further includes a skirt attached to a rear end of the bobbin trunk, and the flange is a rear flange provided at the skirt and attached to a rear end of the bobbin trunk. With this configuration, it is possible to prevent the fishing line from getting jammed between the rear flange and the bobbin trunk.
- According to a fourth aspect of the present invention, in a spool as in any of the first to third aspects, the reinforcement is a metal ring. With this configuration, high strength can be attained at low cost by using for example a commonly used ring-shaped, flat component, such as a washer.
- According to a fifth aspect of the present invention, in a spool as in any of the first to fourth aspects, the bobbin trunk is made of synthetic resin. With this configuration, the reinforcement strengthens the bobbin trunk, even when a bobbin trunk made of synthetic resin with low relative strength is used.
- According to a sixth aspect of the present invention, in a spool as in any of the first to fifth aspects, the bobbin trunk comprises a cylindrical portion made of sheet metal, and an inner cylindrical member made of synthetic resin fitted into the cylindrical portion. With this configuration, an inner cylindrical member made of synthetic resin is fitted into a bobbin trunk made from sheet metal, and the reinforcement is attached to the inner cylindrical member. Thus, the reinforcement reinforces the relative strength of the inner cylindrical member.
- According to a seventh aspect of the present invention, in a spool as in the sixth aspect, the reinforcement is arranged between the flange and an edge of the inner cylindrical member. With this configuration, it is possible to reinforce the relative strength of the edge of the inner cylindrical member in particular.
- According to an eighth aspect of the present invention, in a spool as in the sixth aspect, the reinforcement is formed unitarily with the cylindrical portion, and an edge of the cylindrical portion is extended inwards. With this configuration, it is possible to reinforce the strength of the bobbin trunk by forming for example a cylindrical inner flange provided with a bottom at the end of the bobbin trunk.
- According to a ninth aspect of the present invention, in a spool as in any of the first to eighth aspects, the reinforcement is formed unitarily with the flange, and the inner edge of the flange is extended inwards. With this configuration, it is possible to reinforce the strength of the bobbin trunk by forming for example a cylindrical inner flange provided with a bottom unitarily with the flange.
- According to a tenth aspect of the present invention, in a spool as in any of the first to ninth aspects, the reinforcement is an engaged portion provided at the flange and engaged with an engagement portion provided at one end of the bobbin trunk. With this configuration, it is possible to reinforce the relative strength of the flange with respect to the bobbin trunk by engaging an engagement portion of the bobbin trunk with an annular engaged portion formed in the flange, for example.

front flange 8 is an annular member made of a stainless alloy that has been subjected to a curling process and folded over to the rear. Thefront flange 8 is fastened by screwing it to theinner barrel 7 d. - The front-
flange fastening member 9 is fastened with screws to theinner barrel 7 d, so that thefront flange 8 is held between the front-flange fastening member 9 and the front end of thebobbin trunk 7 a. The female threaded holes in the front-flange fastening member 9 are arranged at different positions than the female holes of thefront flange 8. - The
reinforcement 70 is, for example, a ring-shaped, plate-form ring member made of metal, such as a washer. Through-holes connecting the female threaded holes in theinner barrel 7 d, thefront flange 8, and the front-flange fastening member 9 are formed at a plurality of locations in thereinforcement 70. - In this
spool 4, ametal reinforcement 70 is attached to theinner barrel 7 d, so that the relative strength of theinner barrel 7 d is reinforced. Consequently, deformations of thebobbin trunk 7 a are restrained, so that the fishing line is unlikely to get jammed in between thebobbin trunk 7 a and thefront flange 8. - Other Embodiments
- (a) In the foregoing principal embodiment, the reinforcement is fastened with screws to the inner barrel. However, the invention is not thus limited, and the reinforcement may also be fastened by press fitting, gluing, welding or any other suitable method.
- (b) In the foregoing principal embodiment, the bobbin trunk includes a tubular section made by press-forming a sheet of aluminum alloy, and separately formed inner barrel made of synthetic resin. However, a bobbin trunk17 a made of synthetic resin may also be formed unitarily with a
skirt 17 b, as shown in FIG. 4. - (c) In the foregoing principal embodiment, the reinforcement is formed separately from the bobbin trunk, but it may also be formed unitarily with the bobbin trunk. As shown in FIG. 5 for example, a
reinforcement 270 may also be an inner flange 7 e formed by bending and extending the front end oftubular section 17 c inward circumferentially. The inner flange 7 e can be press-formed and bent inwards, in contact with the front end of theinner barrel 17 d, and held between the front end of theinner barrel 17 d andfront flange 18. - (d) In the foregoing principal embodiment, the reinforcement is provided between the front end of the bobbin trunk and the front flange, but the invention is not thus limited, and the metal reinforcement may be press fit frontward into a synthetic resin bobbin trunk at a position removed from the
front flange 8. - (e) As shown in FIG. 6, a
tubular reinforcement 370 provided on afront flange 28 may be press fit into the front-end inner margin of abobbin trunk 27 a made of synthetic resin. In the portion where the bent over part of thefront flange 28 is joined to thebobbin trunk 27 a, thefront flange 28 and thebobbin trunk 27 a each are approximately flat, making damage unlikely despite fishing line contacting on them. - (f) As shown in FIG. 7, the reinforcement may also be a ring-shaped engaged
portion 8 a formed in afront flange 38, into which an engagingportion 7 f provided on the front end of thebobbin trunk 7 a engages. Furthermore, as shown in FIG. 8 anengagement portion 17 f on a syntheticresin bobbin trunk 37 a may engage with an engagement portion 18 a (the reinforcement) on thefront flange 38. - (g) As shown in FIG. 9, a
skirt 27 b having arear flange 7 g may be provided separately from abobbin trunk 47 a, where the reinforcement may be aninner flange 17 e extending inward circumferentially from the inner rim of therear flange 7 g and formed unitarily therewith. And as shown in FIG. 10, it is also possible to provide areinforcement 470 may be provided separately from therear flange 7 g at the rear end of thebobbin trunk 47 a. - In accordance with the present invention, a reinforcement is attached to the flange attachment side of the bobbin trunk of a spinning reel spool, thereby strengthening the bobbin trunk to curb bobbin trunk deformation. Consequently, fishing line is less likely to jam in between the bobbin trunk and the flange.
- While only selected embodiments have been chosen to illustrate the present invention, to those skilled in the art it will be apparent from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. Furthermore, the foregoing description of the embodiments according to the present invention is provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
