Description

[Detailed Description of the Invention] The present invention relates to an improvement of a spool attachment/detachment device for a spinning reel.

In a spinning reel, the spool can be replaced with one touch by pressing the push button on the top of the spool and using a tapered cam to expand the clamping part of the ring spring that engages with the locking neck of the spool shaft. The spool is separated from the spool shaft in Utility Model Application No. 55-149373, Utility Model Publication No. 149373.
It is known from Publication No. 52-818, etc.

However, the conventional system requires a locking mechanism between the push button barrel and the fixed cap, and the ring spring must be set alone during assembly, making alignment difficult.

The present invention improves these defects and facilitates manufacturing and assembly with a simple configuration. A spool shaft having a locking neck at the tip is fitted onto the spool, and a cap tube is detachably attached to the top of the spool. A ring spring is interposed between the lower end of the cap tube and the spool, and both ends of the ring spring engage with the locking neck of the spool shaft. Further, a push button tube having an annular body integrally formed with an annular body at the lower end and tapered notches on both sides of the upper part thereof is slidably fitted, and both ends of the ring spring are engaged with the tapered notches. be.

An embodiment of the present invention will be described with reference to the drawings. A spool shaft 2 having a locking neck 1 formed at its tip is fitted into a spool 3, and a cap cylinder 4 is removably screwed onto the top of the spool 3. A ring spring 5 is interposed between the lower end of the cap cylinder 4 and the spool 3, and its ends 5', 5' are engaged with and clamped to the locking neck 1.

Further, a push button cylinder 6 that fits into the tip of the spool shaft 2 is slidably fitted into the cap cylinder 4, and a ring-shaped body 7 is formed at the lower end of the push button cylinder 6 on both sides of the upper part. Tapered notches 8, 8 are integrally formed, and both ends 5' of the ring spring 5,
5' engages with the taper notches 8, 8, and the push button cylinder 6
prevents it from falling off. In the figure, 9 is a mounting taper formed at the tip of the spool shaft 2, 10 is a locking pin protruding from the spool shaft 2, and 11 is a locking pin 1.
0 engagement part.

Since the embodiment of the present invention is constructed as described above, when removing the spool 3 from the spool shaft 2,
When the push button cylinder 6 is pressed and slid downward, its tapered notches 8, 8 press both ends 5', 5' of the ring spring 5 outward and expand them to the diameter of the spool shaft 2, so that the spool 3 is spooled. The spool 3 can be pulled out and separated from the shaft 2, and when the spool 3 is to be installed, when the spool 3 is pushed into the spool shaft 2 in the opposite manner to the above, the tapered portion 9 for installation of the spool shaft 2 will cause the both ends 5 of the ring spring 5 to be separated. ', 5' are widened and both ends 5', 5' are clamped and locked to the locking neck, and are attached to the spool shaft 2.

Although the above embodiment shows that the cap tube 4 is removably fixed to the spool 3 by screwing means, the cap tube 4 is not limited to this, and for example, as shown in FIG. A groove 12 is formed in the axial direction on the inner circumferential surface of the fitting hole of the cap tube 4 of the spool 3, and an annular locking groove 13 is provided at the tip thereof to communicate with the groove. A locking piece 14 that can be freely inserted into the groove 12 is provided protrudingly, and the locking piece 14 is rotated after fitting the cap tube 4 to the spool 3 while inserting the locking piece 14 into the groove 12.
The cap tube 4 can also be fixed to the spool 3 by engaging with the annular locking groove 13.

The present invention is a one-touch replacement system for this type of spool, in which an annular body is integrally formed at the lower end of the push button cylinder and a tapered notch is formed on both sides of the upper part, and both ends of a ring spring are engaged with the tapered notch. Therefore, the push button tube and the cap tube can be locked using the ring spring without providing a locking mechanism between them, and the push button tube and ring spring can be set in the cap tube in advance during manufacturing and assembly. , it is easy to assemble without the trouble of attaching each to the spool individually or aligning the springs as in the past, and the number of parts is small, so the configuration is simple and costs are reduced. It has excellent features and practicality.
