Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a structure for mounting a reel sheet of a fishing rod having a reel sheet. 2. Description of the Related Art Conventionally, a reel sheet has been used for detachably mounting a reel on a fishing rod. For example, in Japanese Utility Model Laid-Open Publication No. 1-168166, as shown in FIG. 4, the reel sheet has a tubular shape that can be fitted and fixed to the outside of the rod body (P), and has a fixed hood (not shown) on the outside of the front part thereof. Reel seat body (T) that is fixed and has a screw portion (S) on the rear outer surface
And a tightening screw cylinder (V) having a cylindrical shape that can be screwed with the screw portion (S) and a moving hood portion (U) engaged with a front portion thereof. In this reel sheet, the reel sheet body (T) in which the tightening screw cylinder (V) is screwed is fitted and fixed to the rod body (P),
The handle tube (W) is attached to the rod body by fitting the tip end of the handle tube (W) to the rear end surface of the reel seat body (T) outside the end of the rod body (P). [0003] Further, since the movable hood does not rotate along the outer peripheral surface of the rod main body but needs to advance and retreat in the axial direction of the rod main body toward the fixed hood, the reel seat main body (T) is usually used.
A groove (not shown) is provided within the movement range of the upper moving hood (U), and a projection that engages with this groove is provided on the inner surface of the moving hood (U) to engage them. The part (U) and the tightening screw cylinder (V) are rotatably connected to each other by a goodwill. In a fishing rod having a reel sheet attached thereto, salt and dust are liable to be clogged in the thread portion of the reel sheet body, which hinders the advancement and retreat of the tightening screw cylinder, and makes it difficult to attach and detach the reel mounting leg. It is hindering. In this regard, in the above-mentioned publication, the diameter of the handle tube (W) is adjusted so that the tightening screw tube (V) and the moving hood portion (U) can move backward from the screw portion (S). The diameter of the valley is equal to or smaller than the diameter of the valley, and the tightening screw cylinder (V) and the movable hood (U) can be moved forward and backward within the above range, so that the screw (S) can be easily exposed. However, in this configuration, the engagement between the groove provided in the reel seat body and the movable hood is disengaged by the handle cylinder, and when the tightening screw cylinder is advanced in the retightening direction, the reel seat body and the movable hood are disengaged. It has to be reengaged, and this operation is complicated, and this makes the fishing fun. Accordingly, an object of the present invention is to solve the problem that the screw portion of the reel seat body can be easily exposed, and at this time, the moving hood portion engages with the reel seat body. An object of the present invention is to provide a structure for mounting a reel sheet having a configuration capable of maintaining a releasable state. According to the invention of claim 1 of the present application, [a] the rod body (2) and [b]
A gripping tube portion (4) fitted and fixed to the outer end of the rod main body,
(C) The rod body (4) of the rod body is fitted and fixed to the front outer side, a fixed hood (3a) is fixed to a front outer surface, and a screw portion (3b) is formed on a rear outer surface. The reel seat body (3) provided with a guide groove (3c) extending in the axial direction through the portion (3b) to the rear end, and (d) the screw portion (3b) of the reel seat body (3) can be screwed. A screw cylinder (6) with a screw groove formed on the inner wall surface,
(E) A movable hood (5a), which is loosely fitted to the front outside of the screw portion (3b) of the reel seat body (3) and can fix the reel mounting leg (8) with the fixed hood (3a), is provided at the front. Reel mounting having a ridge (5b) formed on the inner wall surface, the rear portion of which is rotatably engaged with the screw cylinder (6), and furthermore, the ridge (5b) is engaged with the guide groove (3c) of the reel seat body (3). A leg-fixing cylinder (5), and (f) a ring-shaped elastic body mounted on the outer surface of the rod body between the rear end (31) of the reel seat body and the front end (41) of the gripping cylinder portion and elastically contacting these end faces. When the screw cylinder (6) is unscrewed from the screw portion (3b) and retracted, at least the front end of the reel mounting leg fixing cylinder (5) is a ring-shaped elastic body (7). The outer diameter (A) of the gripping cylinder portion in the range in which it can retreat to the rear of the screw-shaped elastic body is set smaller than the diameter (B) of the valley portion of the screw portion (3b).
The outermost diameter (C) of (7) is larger than the outer diameter (A) of the front end of the gripping cylinder part (4) and is equal to, but smaller than, the valley diameter (B) of the screw part (3b). Is set, and the ridges (5
b) is fixed to the ring-shaped elastic body (7) and
(1) The reel seat mounting structure (1) characterized by being adjusted to the degree of protrusion that can be exceeded by the elastic deformation of (7).
Is provided. [0008] The reel sheet mounting structure (1) of the present invention comprises:
The rear end (31) of the reel seat body (3) and the front end (4
A ring-shaped elastic body (7) is interposed on the outer surface of the rod body between 1) and the end faces (31) and (41) so as to make elastic contact with these end faces (31) and (41). The outer diameter (A) of the reel mounting leg fixed cylinder (5) engaging with this groove, the degree of protrusion of the ridge (5b) on the inner surface,
Except for adjusting the outermost diameter (C) of the ring-shaped elastic body (7) as described later, those known in the art can be used as they are. In the present invention, the ring-shaped elastic body (7)
, A normal O-ring can be used, but the present invention is not limited to this. The ring-shaped elastic body (7) acts to temporarily lock the ridge (5b) of the reel mounting leg fixing cylinder (5) by defining its outermost diameter (C) as described later. However, besides this, it is also possible to adopt a configuration in which the tight state of the screw cylinder (6) can be maintained by increasing the pressure and friction with the inner wall surface of the screw cylinder (6). In the present invention, the outer diameter (A) from the front end of the gripping cylinder (4) to a predetermined range is the diameter of the valley of the screw (3b).
It is set smaller than (B). The above-mentioned predetermined range means that the screw tube (6) is unscrewed from the screw portion (3b) and retracted, and is engaged with at least the screw tube (6) from the front end (41) of the grip tube portion (4). The range in which the front end of the combined reel mounting leg fixing cylinder (5) can retreat to the rear of the ring-shaped elastic body (7). In the present invention, the outermost diameter (C) of the ring-shaped elastic body (7) is larger than the outer diameter (A) of the front end of the gripping cylinder (4) and the diameter of the valley of the screw (3b). The diameter is set to be equal to or smaller than (B). In the present invention, the reel mounting leg fixing cylinder (5)
The protrusion (5b) is adjusted to such an extent that the degree of protrusion can be locked to the ring-shaped elastic body (7) and exceeded by the elastic deformation of the ring-shaped elastic body (7). In the present invention, the guide groove (3c) of the reel seat body (3) may have a depth sufficient to accommodate the ridge () having the above-mentioned degree of protrusion. For example, the groove bottom is located between the outer diameter (A) of the front end of the gripping cylinder (4) and the diameter of the valley (B) of the screw (3b), and the outermost diameter of the ring-shaped elastic body (7) (C And the like. According to the invention of claim 1 of the present application, the projection (5b) of the reel mounting leg fixing cylinder (5) engages with the guide groove (3c) of the reel seat body (3). In a state where the screw tube (6) is screwed with the screw portion (3b) of the reel seat body (3), when the screw tube (6) is rotated and moved forward, the reel mounting leg fixing tube ( 5) advances straight along the guide groove (3c) without rotating, the moving hood (5a) comes close to the fixed hood (3a), and the reel mounting leg (8) is fixed between them. On the other hand, if the screw cylinder (6) in the above-mentioned mounted state is rotated in the opposite direction and retracted, the reel mounting leg fixing cylinder (5) will be in the guide groove.
Retreat along (3c), moving hood (5a) becomes fixed hood (3a)
Separated from As the screw cylinder (6) continues to retreat, the outer diameter (A) of the front end of the gripping cylinder (4) is set smaller than the root diameter (B) of the screw (3b). Since the outermost diameter (C) of the ring-shaped elastic body (7) is set to be equal to or smaller than the valley diameter (B) of the screw portion (3b), the screw cylinder (6) is The screw is released beyond the ring-shaped elastic body (7) behind (3b), and the grip tube (4)
Is loosely fitted. The reel mounting leg fixing cylinder (5) engaged with the screw cylinder (6) in the loosely fitted state has the ridge (5b) on its inner surface rearward along the guide groove (3c) as it is. The ring-shaped elastic body (7) is in contact with the rear end of the guide groove (3c), and the ridge (5b) is locked to this ring-shaped elastic body (7). Here, once, the reel mounting leg fixing cylinder (5) is prevented from moving backward, and the engagement between the ridge (5b) and the guide groove (3c) is maintained. The ridge (5b) can exceed the ring-shaped elastic body (7) by elastically deforming it. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of a reel sheet mounting structure of the present invention will be described with reference to the drawings, but the present invention is not limited to this. Embodiment 1 FIG. 1 is a schematic cutaway view of an essential part illustrating an example of a reel sheet mounting structure (1) of the present invention.

(A) is set smaller than the diameter (B) of the valley portion of the screw portion (3b) so that the front end of the reel mounting leg fixing cylinder (5) can be retracted to the rear of the screw portion (3b). Although not shown, a portion behind the front end (4a) is formed in a shape suitable for gripping. A moving hood (5a) is formed at the front of the reel mounting leg fixing leg (5), and the rear end is formed into a shape suitable for connection with the front end of the screw tube (6). ing. This connection is configured such that the reel mounting leg fixing cylinder (5) and the screw cylinder (6) can rotate relative to each other about the axis. Also, on the inner wall of the reel mounting leg fixed cylinder (5), the guide groove of the reel seat body (3)
A ridge (5b) engaging with (3c) is formed. The screw tube (6) is screwed into the screw portion (3b) and fastened forward to fix the reel mounting leg (8) between the fixed hood (3a) and the movable hood (5a). At this time, the rear end of the screw cylinder (6) is configured to be positioned on the ring-shaped elastic body (7), and at this time, the rear end inner wall surface can press the outer peripheral part of the ring-shaped elastic body. It is formed to have a projecting surface (6b). Although not described in detail here, instead of forming the swelling surface and pressing the ring-like elastic body, a swelling part is formed on at least a part of the outer surface of the ring-like elastic body, and the swelling part is formed. May be pressed by the inner wall surface of the rear end of the screw cylinder. In this embodiment, the ring-shaped elastic body (7) is
For example, it is composed of an O-ring made of an elastomer known under the trade name of Sunplane. Next, the guide groove (3c) and the valley diameter of the screw portion (3b)
(B), the front end outer diameter (A) of the gripping cylinder (4), and the ridge (5b),
The relationship between the outermost diameter (C) of the ring-shaped elastic body (7) and the outermost diameter (C) will be described with reference to FIG. 3, but the ridge is not shown in the figure. It is almost equivalent to the groove bottom line (3d) of (3c), and the line will be described. In the guide groove (3c), the position of the groove bottom line (3d) is
(4) between the front end outer diameter (A) and the valley diameter (B) of the screw portion (3b), and smaller than the outermost diameter (C) of the ring-shaped elastic body (7). Is set. The outermost diameter (C) of the ring-shaped elastic body (7) is larger than the outer diameter (A) of the front end of the gripping cylinder (4), and is larger than the valley diameter (B) of the screw part (3b). It is set small. The protruding end (= groove bottom line (3d)) of the ridge of the reel mounting leg fixing cylinder (5) should be smaller in diameter than the outermost diameter (C) of the ring-shaped elastic body (7). Is set. The mounting structure (1) configured as described above
The operation of will be described. The protrusion (5b) of the reel mounting leg fixing cylinder (5) engages with the guide groove (3c) of the reel seat body (3),
In a state where the screw tube (6) is screwed with the screw portion (3b) of the reel seat body (3), when the screw tube (6) is rotated and moved forward, the reel mounting leg fixing tube (5 The guide groove (3)
Moving forward along c), the movable hood (5a) is close to the fixed hood (3a), and clamps the reel mounting leg (8) between them to fix it. At this time, the bulging surface (6b) formed on the inner wall of the screw cylinder (6) presses the ring-shaped elastic body (7). As a result, the ring-shaped elastic body (7) is elastically deformed and comes into sufficient contact with the swelling surface (6b) to generate a frictional force, and the screw cylinder (6) is firmly fastened at that portion, so that the reel mounting is performed. leg
The fastening force is not loosened by the force applied to (8) or the movement or force transmitted to the rod body (2). On the other hand, when the screw cylinder (6) in the mounted state is rotated in the opposite direction and retracted, the reel mounting leg fixing cylinder (5) does not rotate but retreats along the guide groove (3c) and moves. The hood (5a) is separated from the fixed hood (3a), and the reel mounting leg (8) can be removed from the reel seat body (3). As the screw cylinder (6) continues to retreat, the outer diameter (A) of the front end of the grip cylinder (4) is set smaller than the valley diameter (B) of the screw (3b). Since the outermost diameter (C) of the ring-shaped elastic body (7) is also set smaller than the valley diameter (B) of the screw portion (3b), the screw cylinder (6) is formed of the screw portion (3b). It can smoothly pass over the rear ring-shaped elastic body (7), and is in a state of being loosely fitted to the front end of the grip tube (4). The reel mounting leg fixing cylinder (5) engaged with the screw cylinder (6) in the loosely fitted state has the ridge (5b) on its inner surface rearward as it is along the guide groove (3c). The ring-shaped elastic body (7) is in contact with the rear end of the guide groove (3c), and the outermost diameter (C) of the ring-shaped elastic body (7) is Article
Since it is larger than the protruding end of (5b), the ridge (5b) is temporarily locked here, and the reel mounting leg fixing cylinder (5) is prevented from moving backward. In this state, the screw cylinder
Even if the screwing of the screw (6) and the screw (3b) is released, the ridge (5
Since the engagement between b) and the guide groove (3c) is maintained, the reel mounting leg fixing cylinder (5) can be advanced only by screwing the screw cylinder (6) again into the screw portion (3b). it can. In the above-mentioned locked state, the screw cylinder (6)
If it is moved backward, the ridge (5b) becomes a ring-shaped elastic body (7)
Can be exceeded by elastically deforming the reel mounting leg fixing cylinder (5), so that the screw portion (3b) can be entirely exposed. According to the invention of claim 1 of the present application, when the screw tube is retracted, the screwing of the screw tube and the screw portion is released, and the screw is attached to the front end of the gripping tube portion. Even when the tube is loosely fitted, the protrusion on the inner surface of the fixed reel mounting leg fixed to the screw tube is locked by the ring-shaped elastic body, thereby guiding the protrusion and the reel seat body. Since the engagement with the groove is maintained, the movable hood can be moved forward again only by screwing the screw cylinder into the screw portion and tightening, and the replacement of the reel mounting leg can be easily performed. Further, from the state where the screw cylinder is disengaged from the screw portion and the ridge is engaged with the guide groove and is engaged with the ring-shaped elastic body, the ring-shaped elastic body is deformed to forcibly press the ridge. The screw portion can be retracted by moving beyond this (unlocking) and the screw portion can be exposed, so that salt, dust, and the like deposited on the screw portion can be easily removed.
