Description

[Detailed Description of the Invention] The present invention relates to a cylindrical reel attachment device for attaching a reel, which is a type of fishing gear, and in particular a sliding sleeve for fixing the foot of the reel and the sliding sleeve. This relates to the structure of the retaining portion with the screw ring which is the moving means.

Although this seed cylinder type reel seat has already been used by many anglers, it has the following disadvantages.

That is, the cylindrical reel seat is provided with a fixed sleeve and a sliding sleeve facing each other, and the mounting foot of the reel is held between the fixed sleeve and the sliding sleeve.

The sliding sleeve side is moved forward and backward by a screw ring, and when the screw ring is loosened, the holding of the reel mounting foot by the sliding sleeve is released and the reel is removed.

However, once the sliding sleeve has held the reel mounting foot, it often bites strongly due to the wedge action, and the sliding sleeve does not move back just by loosening the screw, making removal extremely troublesome. was there.

Although prior art techniques such as conventional methods have existed to solve these problems, they have not always been able to sufficiently solve the problems.

First, as one of the conventional types, there is an engagement structure of a sliding sleeve and a screw ring in a cylindrical fishing reel seat disclosed in Japanese Utility Model Application No. 55-149372.

In this device, a sliding sleeve and a screw ring are rotatably fitted into each other through male and female unevenness, and the sliding sleeve also retreats as the screw ring retreats.

However, in this conventional type, the screw ring is made of an elastic plastic material, and when the two are assembled, this elastic deformation helps the connection, but once the screw ring and sliding sleeve are assembled, Since there is no special means to prevent the screw ring fitted on the outside of the screw ring side from expanding, if the sliding sleeve is bitten into the mounting foot of the reel as described above, the screw ring cannot be forced. If you loosen it, the joint will expand elastically.

As a conventional example that focused on the problem of the sliding sleeve becoming uncoupled and tried to solve the problem, there is a reel sea 1 disclosed in Utility Model Application Publication No. 56-50272.
− exists.

This has a so-called hoop-shaped reinforcing ring fitted onto the spiral ring to prevent it from expanding.

However, in this case, the reinforcing ring was completely separate from the spiral ring, and no active measures were taken to connect the two, so there was a risk that the reinforcing ring would come off even after completing the vows.

Also, during assembly, this product is constructed with the intention that the spiral ring side, which is a member located on the outside, will expand temporarily, so it is necessary to loosely fit the reinforcing ring into the sliding sleeve in advance during assembly. It also has the disadvantage that the assembly is extremely troublesome.

Here, the present invention proposes a new mutual combination structure of a screw ring and a sliding sleeve that eliminates all the drawbacks of these conventional types.

In other words, in order to prevent the sliding sleeve and the screw ring from coming off each other, the inner circumferential surface of the inner member, which is originally fitted in a male-female relationship, must be in contact with the cylindrical body. Focusing on the fact that inward deformation is not allowed after assembly, when assembling the sliding sleeve and screw ring, only the inner members are deformed inward, while the outer members are This is designed to prevent any deformation that would expand outwards, thereby preventing an accident when the two are separated during use.

Specifically, in this kind of cylindrical reel seat, the sliding sleeve and the screw ring are connected to each other in a male-male relationship that allows them to rotate freely, and the structure of the member located on the outside of this connection part is set high and deformed. The object is distantly related to the above-mentioned object by having a structure in which a member fitted inside is elastically deformable inward.

The present invention will now be explained based on illustrated embodiments.

FIG. 1 is a perspective view showing the cylindrical reel attachment device according to the present invention in use, and reference numeral 1 denotes a cylindrical body made of a plastic material reinforced with glass fiber or the like, as an example.

As an example, in this case, a fixed sleeve 2 is externally fitted in front of the fixed sleeve 2, and a sliding sleeve 3 is attached to the other end opposite to this, and a screw ring 4 is rotatably attached to the sliding sleeve 3. engage.

These are the main components and will be described in further detail.

First, the cylindrical body 1 is provided with a flange 5 at its front end, and a keyway 6 is carved in the range from the front end to the rear end.

The outer diameter of the portion 7 on the flange side is made somewhat thicker to serve as a fitting portion for the fixed hood.

On the other hand, a male spiral 8 is carved over a certain range at the end of the cylindrical body on the sliding sleeve side.

Therefore, the fixed sleeve 2 is externally fitted onto the fitting part 7 side, and when fitting the fixed sleeve 2, the fixed sleeve is inserted from the side where the male spiral 8 is provided, and at this time, the fixed sleeve 2 is inserted from the side where the male spiral 8 is provided. Since there is some difference between the inner diameter and the outer diameter of the cylindrical body, the fixing sleeve moves relatively easily and reaches the fitting portion 7, where it is press-fitted as the outer diameter of the cylindrical body increases. It is fixed to .

Incidentally, at this time of fitting, the engaging protrusion 2A of the fixed slave 2 is fitted into the key groove 6, so that the hood 2B formed on the fixed sleeve is positioned.

On the other hand, the sliding sleeve has a locking projection 3A on its lower surface and a hood 3B on the opposite side.

Furthermore, the screw ring that engages with this has a male thread 4A on its inside.

We will now further discuss the joint between the two. First, although either the screw ring or the sliding sleeve may be located on the outside or the inside, in this embodiment, as an example, an example will be given in which the screw ring side is located on the outside of the sliding sleeve. It is something.

First, in the case shown in FIGS. 1 to 4, the screw ring 4 is made of a metal material and has sufficient rigidity.

On the other hand, the sliding sleeve 3 is made of a flexible plastic material.

Of course, this sliding sleeve does not need to be entirely made of plastic material, and it is also possible to partially apply a reinforcing metal member to the portion of the hood 3B that receives the mounting leg of the reel.

As shown in an enlarged view in FIG. 4, the rear end of the sliding sleeve 3 has an engaging protrusion 3a on its outer periphery, and an engaging recess 3b is formed in front of the engaging protrusion 3a.

On the other hand, the helical ring side has an engaging protrusion 4a formed inwardly at its front end, and furthermore an engaging groove 4b is formed at its rearward inner side.

The method of assembling the sliding sleeve and the screw ring in this embodiment is as follows: First, the sliding sleeve is attached to the inside of the metal screw ring by utilizing the inward elastic deformation caused by the sliding sleeve being made of plastic material. It is intended to fit.

After fitting from the beginning, the engaging protrusions 3a, 4a of both
By setting the dimensions of the and engaging grooves 3b and 4b, both can be assembled to be rotatable with respect to each other.

By the way, the basic technical idea of the present invention is to utilize the method of preventing deformation such as expansion of the outer member between the female-male coupling screw ring and the sliding sleeve from occurring. Therefore, it is not necessarily required that all the members located on the outside be made of metal materials in order to prevent expansion.

That is, in the embodiment shown in FIGS. 5 and 6, the screw ring, which is the outer member, is made of plastic material, and a metal ring 9 is fitted on the outside of the retaining portion to prevent the screw ring from deforming. groove 4 into which the metal ring 9 is inserted.
Provide C.

In the assembly method of this embodiment, since the plastic screw ring is deformable inwardly, the metal ring 9 is first press-fitted into the receiving groove 4C.

Thereafter, as in the case of the previous embodiment, the sliding sleeve is applied to the end of the screw ring, and the sliding sleeve is engaged at once by utilizing its inward elastic deformation.

Incidentally, in this embodiment, the main body of the sliding sleeve is made of plastic, but since a metal hood frame 3C is provided around it, in this case, before press-fitting the two, the sliding sleeve 3 is The metal hood frame 3C is fitted onto the outside.

The present invention has the configuration described above,
When this is assembled into a cylindrical body and used, the member (sliding sleeve 3 in this embodiment) located on the inside of the engaging portion of the two is in contact with the outside of the cylindrical body. On the other hand, the spiral ring, which is a member located on the outside, is configured so that it cannot be deformed outward, so it is not possible to expand the member located on the outside or the member located on the inside. This completely prevents the two from coming off due to deformation caused by contraction.

It should be noted that the inner member would be difficult to deform if it were made of a metal member, but in order to allow deformation, it was partially constructed with snots to allow for elastic deformation. There is no difference from the beginning.

As described above, in the present invention, after the screw ring and sliding sleeve are assembled to the cylindrical body and completed, the presence of the cylindrical body prevents both from expanding or contracting deformation. , uncoupling is completely prevented.

Furthermore, during assembly, the inner members are easily compressed and deformed inward, so that they can be easily press-fitted, and assembly is not difficult.

Furthermore, in the case of the embodiment shown in Figs. 5 and 6, when the metal ring is fitted onto the outer periphery of the screw ring, the screw ring easily deforms inward, so that the assembly can be easily performed and the metal ring can be easily fitted into the receiving groove. It can be contained.

After the metal tongue is fitted onto the cylindrical body and completed, the spiral ring does not shrink inward due to the presence of the sliding sleeve and the cylindrical body, and together with the presence of the receiving groove, the metal The +7 ring never comes off.
