Abstract

PURPOSE:To obtain a shaking out rod capable of avoiding immobilizing a small- diameter rod body relatively to the interior of a large-diameter rod body by falling into a fixed state incapable of housing due to the sticking of water to a joined part, when the small-diameter rod body is drawn out of the large- diameter rod body. CONSTITUTION:A bulged part (1A) of a small-diameter rod body 1 is covered with a masking tape 7 and coating is then applied from the upper part of the tape 7. The rod is constructed so as to form plural protrusions 3 from the coating bonded through through-holes (7A) of the masking tape 7 to the large- diameter bulged part (1A) and bring the protrusions 3 into pressure contact with the inner peripheral surface (2A) of the joint end of the large-diameter rod body 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing-out device in which a small-diameter rod body is attached to a large-diameter rod body so that the small-diameter rod body can be retracted and retracted, and a fitting portion for fixing the small-diameter rod body to the large-diameter rod body is formed. The present invention relates to a rod and a manufacturing method thereof.

[0002]

2. Description of the Related Art In this type of blow-out rod, conventionally, a bulging portion is formed at the rear end of a small-diameter rod body to form a mating portion, and the outer peripheral surface of the bulging portion is a smooth surface without unevenness. To finish,
In the state where the small-diameter rod body is pulled out, the bulging portion is internally fitted and pressure-contacted to the inner peripheral surface of the tip of the large-diameter rod body. In this pressure contact state, the tip position of the large-diameter rod body is generally located at an intermediate position behind the tip of the bulging portion.

[0003]

When the outer peripheral surface of the bulging portion is pressed against the inner peripheral surface of the distal end of the large-diameter rod body over the entire surface as described above, there is play at the time of fitting and fixing. If the fitting operation is good, and the tip position of the large-diameter rod body is set to an intermediate position behind the tip of the bulging part, the fish will catch the needle. Even when the rod is greatly curved, the curvature of the bend does not bend like a knot at this fitting part, and the bending line of the rod is connected smoothly and continuously, so the load is distributed continuously. There is a side that is easy to handle. However, since the bulging portion is in contact with the entire surface, when water adheres to the fitting portion, the small diameter rod body and the large diameter rod body are fixed, and the fixed state is fixed. In many cases, the small diameter rod body could not be released and could not be stored inside the large diameter rod body. In addition, when dust or sand adheres to the inner surface of the tip of the large-diameter rod when the small-diameter rod moves in or out, not only is the bulging part damaged, but also the outer peripheral surface on the tip side of this bulging part. However, since there is little difference between the bulge and the outer diameter, the outer peripheral surface on the tip side may be damaged. This is what is called the so-called rod body barrel slipping phenomenon. In addition, it is necessary to paint the bulging portion of the small-diameter rod body up to a position rearward of the tip end of the large-diameter rod body in the above-mentioned fitted state to maintain its aesthetic appearance, It is necessary to grind a part of the outer peripheral surface of the projecting portion, and substantially,
Precision of the order of micron was required as a painting cost, which made it difficult to manufacture. On the other hand, when the fitting part is not formed without a gap as described above but is manufactured with a certain gap, the trouble such as sticking when wet becomes less, but in fine weather, that is, when dry. During actual fishing, when the core of the rod was in use, the fitting became loose at the hand part and fell, causing problems such as damage to the core. The first object of the present invention is to prevent a sticking phenomenon caused by water adhesion from occurring by providing a simple mechanism at the fitting portion of the small diameter rod body, and at the same time, to provide a core or the like in fine weather. The point is to provide a rod that can prevent the occurrence of problems.

[0004]

The characteristic configuration according to the first aspect of the present invention is to form a bulging portion at one axial end of a small-diameter rod body that can freely move in and out of a large-diameter rod body, and to expand the bulge. The large-diameter rod with the small-diameter rod body fixed to the large-diameter rod body at least on the outer peripheral surface of the outer peripheral surface of the portion and the inner peripheral surface of the tip of the corresponding large-diameter rod body, at least. Inwardly press-fitted to the inner peripheral surface of the body, a plurality of projections made of a coating material of the same quality as the coating material on the surface of the small-diameter rod body are provided, and there is a point where a mating portion for the large-diameter rod body is formed. The effect is as follows.

[0005]

That is, when the bulging portion of the small-diameter rod body is fitted to the inner peripheral surface of the large-diameter rod body, the bulging portion does not come into full contact with the projection. Therefore, even if water adheres, the water does not escape between the projections, so that the small-diameter rod body and the large-diameter rod body are not stuck to each other. Further, even if dust or the like adheres, the dust enters between the protrusions, so that the dust is not caught between the bulging portion and the inner peripheral surface, and the bulging portion is not directly damaged. Also, since the protrusion itself uses a paint material, it has some elasticity, and since it is formed as a protrusion, the bulging portion of the small diameter rod body fits on the inner peripheral surface of the large diameter rod body. When they are fitted together, a slight amount of elastic deformation of the protrusions is expected, so that the fitting and fixing state should be firm without having to manufacture the tip diameter of the protrusions with high precision on the order of microns as in the past. it can. Therefore,
Even when it is dry, the mating part loosens during actual fishing,
Problems such as so-called core drop do not occur.

[0006]

As a result, it is possible to prevent the sticking phenomenon due to the adhesion of water by the formation of the protrusions while maintaining the structure for suppressing the rattling in the fitted state, and to prevent the damage of the rod due to the adhesion of dust, and the like. It is possible to suppress troubles such as core drop. Furthermore, due to the synergistic effect of the point to be a protrusion and the point that the protrusion is made of paint material, the fitting state can be made the same as the conventional one even if the accuracy is relatively loose, so manufacture only the loose portion. Will be easier. Further, even when a large load is applied to the rod, the stress is dispersed through the protrusions, so that the bending of the rod becomes smooth with a constant curvature, and damage or the like is less likely to occur. The second object of the present invention is, in addition to the object of the first invention, to provide a rod in which the fitting force can be easily adjusted and the fitting operation feeling is good.

[0007]

According to a second aspect of the present invention, a bulging portion is formed at one end portion of a small diameter rod body that can freely move in and out of a large diameter rod body in the axial direction, and the bulging portion is formed. The outer peripheral surface of the small diameter rod body is formed into a smooth surface, and a plurality of protrusions made of the same coating material as the coating material on the surface of the small diameter rod body are provided on the hem portion of the small diameter on the tip side from the bulging portion. In a state of being fixed to the large-diameter rod body, the bulging portion and the protrusion are internally fitted pressure contact with the inner peripheral surface of the large-diameter rod body, there is a point that is formed, The effects are as follows.

[0008]

In other words, when the bulging portion of the small-diameter rod body is fitted to the inner peripheral surface of the large-diameter rod body, a smooth surface that contacts the entire surface and a portion-contact surface that only the protrusions contact are formed. By making use of the fact that the pressure contact forces on both sides are different, the fitting fixing force can be arbitrarily changed by appropriately setting the contact areas on both sides. Moreover, in terms of operability when pulling out and fixing the small-diameter rod body, the fitting is smooth because the fitting is started from the projection part with a relatively small contact area, and it is tightly fixed by the smooth surface at the end of the insertion. The stable fixed state can appear.

[0009]

As a result, the fitting fixing force can be easily set, and the fitting operation feeling is also good.

An object of the third invention is, in addition to the object of the first invention, is to provide a rod in which the fitting force can be easily adjusted and the phenomenon of damage to the outer peripheral surface of the small diameter rod body can be avoided in advance. In particular, it is to provide a rod that can effectively avoid the scratching phenomenon even when the diameter of the bulging portion is slightly larger than the diameter of the small diameter rod body but there is almost no difference.

[0011]

According to a third aspect of the present invention, a bulging portion is formed at one axial end of a small diameter rod body that can freely move in and out of a large diameter rod body. From the hem portion of the small diameter on the more distal side, over the range of hanging on the outer peripheral surface of the bulging portion, in a state of fixing the small diameter rod body to the large diameter rod body,
Provided with a plurality of protrusions made of a paint material of the same quality as the paint material on the surface of the small-diameter rod body, which is internally fitted and pressure-contacted to the inner peripheral surface of the large-diameter rod body,
The point is that a mating portion is formed for the large-diameter rod body, and the function and effect thereof are as follows.

[0012]

In other words, by providing protrusions not only on the bulging portion but also on the skirt portion thereof, it is possible to form a protrusion in contact with the inner peripheral surface of the tip of the large-diameter rod body over a wide range. Even if the pressure is small, stable fitting and fixing force can be exerted as a whole. Moreover, when a load is applied to the rod, the load is received not only by the bulging portion but also by the hem portion of the rod through the protrusions, so stress concentrated on the stepped portion at the boundary between the bulging portion and the hem portion is applied. Can be relaxed.

[0013]

As a result, the fitting and fixing force can be easily set, and the rod structure can be strengthened.

An object of the fourth invention is to propose a method for manufacturing a rod which can easily set a fitting tolerance and paint at a fitting portion of a large-diameter rod body and a small-diameter rod body.

[0015]

According to a fourth aspect of the present invention, a masking member having a plurality of through-holes is covered with the masking member, and a coating material is applied on the masking member. The point is that the projection is exposed by removing the masking member, and the function and effect thereof are as follows.

[0016]

Function: In other words, when a coating method such as wrapping a masking member around the mating portion of the rod material after molding and spraying the coating material from above is applied, the coating material adheres to the surface of the mating portion through the through hole. , To form a protrusion. Then, when the masking member is removed, the protrusion appears.

[0017]

As a result, the protrusions can be formed in the coating process, which allows the protrusion forming process to be performed simultaneously with the rod material main body coating process after the rod material is formed. Protrusions can be formed according to the dimensional accuracy of the rod material that is the other party. The fitting and fixing force can be easily set, and the rod structure can be strengthened.
