Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a double-bearing reel, and more specifically, to a double-bearing reel that can be switched between right-hand winding and left-hand winding.

(Prior Art) In general, this type of double-bearing reel has a spool rotatably supported between a pair of left and right side frames, and one side frame is provided with a drive mechanism with a drag mechanism.
This drive mechanism is activated by operating the handle to rotate the spool. Since the above-mentioned handle attachment position is fixed, two types, a right-handed type and a left-handed type, are manufactured separately.

Therefore, recently, in order to solve the inconvenience of manufacturing each reel separately as described above, a double bearing reel has been proposed in which the mounting position of the handle can be changed.

Japanese Patent Application Laid-open No. 12925/1984 has a structure for this, in which a spool is rotatably supported between a pair of side frames, and the rotational force of a handle is transferred to the spool via a drive mechanism having a drag mechanism. In the double bearing reel, an interlocking cylindrical shaft having an axis parallel to the axis of the spool is formed,
A support cylinder shaft is fitted to the outside of the interlocking cylinder shaft, and a drag washer of the drag mechanism and a master gear of the drive mechanism are supported on the support cylinder shaft so as to be rotatably supported between the side frames, A handle shaft with a handle and a drag operating body are formed, and these handle shaft and drag operating body can be selectively attached to one end side or the other end side of the interlocking cylinder shaft.

However, in the above configuration, since there is only one interlocking cylinder shaft supported horizontally across the left and right side frames, when assembling, disassembling, repairing, etc., the interlocking cylinder shaft is The problem is that the shaft protrudes too much, making it difficult to work in that area.
That is, with the splice plate and the bowl-shaped cover integrated, the first
In order to separate the side frames, the bowl-shaped cover of the second side frame must be removed from the side plate, and the retaining ring attached to the support cylinder shaft must be removed. Since it is not possible to separate the frame from the side plate, it is very inconvenient to replace parts in the first side frame, remove the spool, etc.

In addition, when the handle is rotated, the support cylinder shaft is supported by the side frame and rotates, so if dirt, seawater, etc. enter the part where the support cylinder shaft is supported by the side frame, corrosion and sticking may occur. This will prevent smooth rotation.

(Problems to be Solved by the Invention) In view of the conventional circumstances as described above, the present invention allows the reel to be disassembled in units of sets, making it easy to replace parts and attach/detach the spool, as well as to replace the drive mechanism. To provide a double-bearing reel capable of maintaining smooth rotation over a long period of time and having a handle that can be freely replaced on the left or right side.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to provide a hollow spool in one side frame parallel to the axis of the spool which is supported on the left and right side frame rods. A main gear shaft is rotatably supported, and a hollow guide shaft is supported on at least the other side frame on the same axis as the main gear shaft, and a drive mechanism equipped with a drag mechanism is attached to the main gear shaft. A handle attachment shaft is connected and fixed to one end of the handle shaft that is inserted across the main gear shaft and the guide shaft, and the handle and drag adjustment member are attached to the attachment shaft, and the handle shaft is connected to the open end of the main gear shaft or the guide shaft. It can be inserted more selectively, and a set screw is screwed onto the open end of the handle shaft.

The guide shaft supported on the same axis as the main gear shaft is not limited to the structure in which it is installed only across the side plate and plate that constitute the other side frame, but it is also installed from the side end of the main gear shaft supported on one side frame to the other side. It is also possible to have a structure in which the shaft is supported across the side frame.

(Function) The main gear shaft and guide shaft, which are divided into two parts, are supported by the left and right side frames that make up the double-bearing reel.
Insert the handle shaft from one end across both of them, and screw the set screw into the handle shaft from the other end to assemble it into a usable state. Adjust the drag mechanism to drive the driving force from the rotation of the handle. It is transmitted to the spool through a mechanism, and the spool rotates. Further, by removing the set screw, pulling out the handle shaft, inserting it from the opposite side, and screwing on the set screw, the position of the handle can be changed from left to right. Furthermore, when the set screw is removed and the handle shaft is pulled out, the main gear shaft and guide shaft are separated, so the left and right side frames can be disassembled while remaining set.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 to 4 show a structure in which the main gear shaft and the guide shaft are connected and supported between the left and right side frames, A and B are the left and right side frames facing each other at a predetermined interval, In A, a hollow gear box is formed by a base plate 1 and a plate plate 2, and a bearing 3 is mounted on the outer surface of the base plate 1.

(Effects of the invention) As described in detail above, the double bearing reel of the invention has a main gear shaft and a guide shaft that are separate structures and are supported on the side frames A and B, and a double bearing reel that spans between the main gear shaft and the guide shaft. Since it is inserted through the handle shaft and fixed with a set screw, it has the following advantages.

Since the main gear shaft and guide shaft are supported separately, the left and right side frames can be disassembled in the set state by removing the set screws, making it easy to replace and repair parts inside the side frames, and to remove the spool. Replacement etc. can be done easily.

Since the main gear shaft and the guide shaft are separate, the guide shaft can be made of a lightweight material such as an aluminum tube that does not require rigidity, and the weight of the entire reel can be reduced. That is, in the case of a conventional one-piece reel, the entire reel must be made of a rigid brass rod, iron, stainless steel, etc., which has the drawback of increasing the weight of the entire reel.

When disassembled, the guide shaft remains on the side frame B, and since there has never been a long shaft protruding from the side frame A, it has never been the case that it would get in the way during disassembly or repair.

The guide shaft, which rotates when the handle rotates, is covered with a protective cover installed between the side frames.
It is possible to prevent water, seawater, or dust from coming into direct contact with the rotating guide shaft, which eliminates problems such as corrosion of the guide shaft and the heavy rotation of the entire drive mechanism, resulting in stable operation over a long period of time. Can maintain rotation.
