ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fishing rod which is used for fishing after a reel is mounted thereon.
2. Description of the Related Art
In a fishing rod of a type that uses a reel, there is disposed a reel mounding device for fixing a reel to the fishing rod. The reel mounting device comprises a main body portion to be fixedly secured to (or formed integrally with) the fishing rod, and a pair of hood portions respectively including a pair of mutually opposing openings. At least one of the two hood portions is a hood portion of a movable type which can be moved back and forth by a nut member to press against the leg of the reel to thereby fixedly secure the reel to the fishing rod. However, since the reel mounting device operates in various manners in fishing, the movable hood portion can be loosened unexpectedly. A device to prevent such loosened movable hood portion is disclosed in Japanese utility Model Publication No. 2-3258 of Heisei and Japanese Patent Publication No. 10-52195 of Heisei.
In the former, an engaging projection formed in an operation ring is engaged with a rotation preventive groove formed in a screw portion to thereby prevent a screw ring (nut member) from being loosened. Also, in the latter, there is interposed a rotation preventive member between a movable seat portion (movable hood portion) and a nut portion to thereby prevent the nut portion from being loosened.
However, in the former of the above-cited conventional devices, the unexpected loosening of the screw ring can be prevented but, when removing the reel, the operation ring is operated to thereby remove the engagement of the engaging projection with the rotation preventive groove and, after then, the screw ring must be rotated. Therefore, to remove the reel, it is necessary to execute a troublesome operation. Also, in the latter, the rotation preventive member is helpful in preventing the loosening of the nut member but, if a force of a given level or more is applied to the rotation preventive member, the rotation preventive member can be loosened. In this case, if an angler is able to notice a click sound caused by the removal of the above-mentioned engagement and thus tighten the nut portion again, there can be raised no problem. However, if the click sound is too low, then the angler is not be able to notice it. That is, if the angler keeps on fishing without noticing the removal of the engagement, the casting operation can be made inaccurate or the reel can be dropped down. In the structure of the latter citation, the rotation preventive member is interposed between the movable seat portion and nut portion and is normally pressed by the movable seat portion to which a reactive force from the fixation of the reel leg is applied, thereby making it difficult to produce a loud click sound. Therefore, the angler is not be able to notice the click sound and thus the loosened condition of the rotation preventive member.
SUMMARY OF THE INVENTION
The present invention aims at eliminating the drawbacks found in the above-mentioned conventional reel mounting devices. Accordingly, it is an object of the invention to provide a fishing rod of a reel mounting type which not only is able to prevent the unexpected loosening of the fixation of the reel but also, if the reel fixation is loosened, is easy to recognize the loosened reel fixation.
In attaining the above object, according to the invention, there is provided, as a first aspect, a fishing rod of a reel mounting type which comprises: a pair of hood portions respectively disposed back and forth in such a manner that they are opposed to each other, the two hood portions respectively including openings for receiving the leg of a reel; at least one of the pair of hood portions being of a movable type, the movable hood portion being movable back and forth due to the rotation of a nut member; and, elastic mechanism and an engaging portion respectively so disposed as to extend between two of three elements, that is, a main body portion fixedly secured to a rod pipe, the above-mentioned nut member and movable hood portion, the elastic mechanism being formed in one of the above-mentioned two elements, the engaging portion being formed in the other in such a manner that the elastic mechanism can be removably engaged with the engaging portion by a given force, wherein the elastic portion of the elastic mechanism is formed considerably larger than the engaging portion, or the free portion of the elastic mechanism not restricted by the engaging portion is formed larger than the portion of the elastic mechanism contacted with and restricted by the engaging portion.
Here, the term “main body portion”, which is fixedly secured to the rod pipe, may not be a part which is provided separately from the rod pipe, but may be an increased-thickness portion which is formed integrally with the rod pipe. Also, the term “fixedly secured state” may be a state in which the main body portion is fixed to the rod pipe while the reel is mounted on the fishing rod. The term “elastic mechanism” is not always limited to a single part, for example, only a spring, but may be a combination of a part with other part. In the above-cited Japanese Patent Publication No. 10-52195 of Heisei, a combination of a coiled spring 52 with a positioning pin 51 corresponds to this. When the elastic mechanism is compared with the engaging portion which is composed of repeated up and down portions, the size of the engaging portion indicates the size of a smaller one of a down portion and an up portion included in the repeated up and down portions of the engaging portion. The term “considerably larger” means twofold or more; preferably, severalfold or more; and, more preferably, tenfold or more. The nut member and movable hood portion may be provided as separate parts and then fixed to each other, or they may be formed as an integral body, for example, by injection molding or by similar mechanism. Of course, in the latter case, there is substantially no sense in providing elastic mechanism between the nut member and movable hood portion.
According to the invention, there is provided, as a second aspect, a fishing rod of a reel mounting type, comprising: a pair of hood portions respectively disposed back and forth in such a manner that they are opposed to each other, the two hood portions respectively including openings for receiving the leg of a reel; at least one of the pair of hood portions being of a movable type, the movable hood portion being movable back and forth due to the rotation of a nut member; and, elastic mechanism disposed in one of the nut member and a main body portion fixedly secured to a rod pipe, and an engaging portion formed in the other in such a manner that the elastic mechanism can be removably engaged with the engaging portion by a given force, wherein the elastic portion of the elastic mechanism is formed considerably larger than the engaging portion, or the free portion of the elastic mechanism not restricted by the engaging portion is formed larger than the portion of the elastic mechanism contacted with and restricted by the engaging portion.
According to the invention, there is provided, as a third aspect, a fishing rod of a reel mounting type, comprising: a pair of hood portions respectively disposed back and forth in such a manner that they are opposed to each other, the two hood portions respectively including openings for receiving the leg of a reel; at least one of the pair of hood portions being of a movable type, the movable hood portion being movable back and forth due to the rotation of a nut member; and, elastic mechanism disposed in one of the nut member and movable hood portion, and an engaging portion formed in the other in such a manner that the elastic mechanism can be removably engaged with the engaging portion by a given force.
According to the invention, there is provided, as a fourth aspect, a fishing rod of a reel mounting type as set forth in the third aspect, wherein the elastic portion of the ela
