Description

本発明は、釣糸や手芸糸、金属線などの糸条体のほか、包装用テープなどの帯状体を巻きつけておき、必要量を随時引き出すことができる長尺体用スプールに関し、さらに詳しくは、扉部を容易に開き姿勢と閉じ姿勢とに切換でき、閉じ姿勢に切換えた扉部により任意の位置で長尺体の端部を確実に保持できるうえ、巻装部の収容容積を大きくして長尺体の収容長さを長くできる、長尺体用スプールに関する。 The present invention relates to a spool for a long body in which a necessary amount can be pulled out at any time by winding a belt-like body such as a packaging tape in addition to a thread body such as fishing line, handicraft thread, or metal wire. The door can be easily switched between the open position and the closed position, and the end of the long body can be securely held at an arbitrary position by the door section switched to the closed position, and the accommodation volume of the winding part can be increased. It is related with the spool for long bodies which can lengthen the accommodation length of a long body.

一般に、釣糸などの長尺体が巻回されるスプールとしては、例えば、円筒状の胴部とこの胴部の両側端から径方向外側へ延設した一対のフランジ部とを備え、長尺体が巻回される巻装部をこの両フランジ部間で上記の胴部の周囲に形成したものがある(例えば、特許文献１参照。)。 Generally, as a spool on which a long body such as a fishing line is wound, for example, a long body is provided with a cylindrical body and a pair of flange portions extending radially outward from both ends of the body. There is one in which a winding part around which the body is wound is formed around the body part between the two flange parts (see, for example, Patent Document 1).

上記のスプールに巻回された長尺体は、巻き終わりの端部が、例えばフランジ部の適所に形成された切込み部に係止され、長尺体が不用意に解けたり引き出されたりしないようにしてある。しかしながら、この切込み部はフランジ部の周縁の一箇所にのみ形成してあり、長尺体は必ずしもこの切込み部に対応した位置で切断されるとは限らないので、長尺体の長さによっては、巻装部の一周分以上の長さが、この切込み部からはみ出す場合がある。 The long body wound around the spool is locked at the end portion of the winding end, for example, at a notch formed at an appropriate position of the flange portion, so that the long body is not unintentionally unwound or pulled out. It is. However, since this cut portion is formed only at one place on the periphery of the flange portion, and the long body is not necessarily cut at a position corresponding to this cut portion, depending on the length of the long body In some cases, a length equal to or longer than one turn of the winding portion protrudes from the cut portion.

そこで上記の問題点を解消するため、従来、上記の両フランジ部の外周縁部にそれぞれ扉部を延設し、両扉部の外周縁部を互いに近接した閉じ姿勢と互いに離隔した開き姿勢とに切換可能に構成したスプールが提案されている(例えば、特許文献２参照、以下、従来技術という。)。この従来技術では、両扉部を閉じ姿勢に切換えることで、周方向の任意の位置で長尺体の端部が両扉部間に挟持される。 Therefore, in order to solve the above-mentioned problems, conventionally, door portions are extended to the outer peripheral edge portions of the two flange portions, respectively, and the outer peripheral edge portions of the two door portions are closed close to each other and open postures separated from each other. Has been proposed (see, for example, Patent Document 2, hereinafter referred to as the prior art). In this prior art, by switching both doors to the closed posture, the end of the long body is held between the doors at an arbitrary position in the circumferential direction.

特開２００２−１５３１８９号公報JP 2002-153189 A 特許第３８７８１９６号公報Japanese Patent No. 3878196

上記の従来技術は、上記の扉部を薄肉の弾性変形可能な合成樹脂で形成してあり、その先端に環状で厚肉の挟持板を付設してある。この薄肉の両扉部は、上記の挟持板同士が一定の押圧力で確りと押しつけ合うように、フランジ部の径方向外方へ凸となる形状に湾曲させてあり、これにより、閉じ姿勢の両扉部間に長尺体の端部が確実に保持される。 In the above prior art, the door portion is formed of a thin elastically deformable synthetic resin, and an annular and thick holding plate is attached to the tip of the door portion. The thin doors are curved in a shape that protrudes outward in the radial direction of the flange so that the clamping plates are firmly pressed against each other with a constant pressing force. The end of the long body is securely held between the doors.

上記の扉部は、上記の湾曲形状を表裏反転させることで閉じ姿勢と開き姿勢とに切換えられるが、この扉部には先端側周縁部に上記の挟持板が付設されているため、上記の姿勢切換は必ずしも容易でなく、フランジ部の径方向に対して扉部を大きく傾斜させることができない。しかもこの扉部は径方向外方へ凸状に湾曲されているため、フランジ部の径方向に対する扉部の傾斜角度は扉部の先端で最大であり、フランジ部に近接するほど、即ち基端側ほど小さくしてある。これ等の結果、この扉部はフランジ部の半径方向に長い寸法が必要とされ、その分、上記の巻装部が小容積となって、この巻装部に収容できる上記の長尺体が短く制限される問題がある。 The door portion can be switched between a closed posture and an open posture by reversing the curved shape, and the door plate is provided with the clamping plate at the distal end side peripheral portion. The posture switching is not always easy, and the door portion cannot be greatly inclined with respect to the radial direction of the flange portion. In addition, since the door portion is curved in a convex shape outward in the radial direction, the inclination angle of the door portion with respect to the radial direction of the flange portion is maximum at the distal end of the door portion, and the closer to the flange portion, that is, the proximal end The side is smaller. As a result, the door portion needs to have a long dimension in the radial direction of the flange portion, and accordingly, the winding portion has a small volume, and the long body that can be accommodated in the winding portion is obtained. There is a problem that is limited to a short time.

また上記の扉部は薄肉であるため径方向に変形し易く、しかも扉部先端に付設した上記の挟持板は互いに突き合わせただけであるので、閉じ姿勢において挟持板が偏心したり楕円状に変形したりして、一部が径方向へ互いにズレる場合があり、両扉部間に隙間を生じてその部分では上記の長尺体を挟持できなくなる問題がある。 Also, since the door part is thin, it is easily deformed in the radial direction, and the clamping plates attached to the front end of the door only touch each other, so that the clamping plate is eccentric or deformed into an oval shape in the closed position. As a result, there is a case where some of them are displaced from each other in the radial direction, and there is a problem that a gap is generated between the door portions, and the long body cannot be held at that portion.

本発明の技術的課題は、上記の問題点を解消し、扉部を容易に開き姿勢と閉じ姿勢とに切換でき、閉じ姿勢に切換えた扉部により任意の位置で長尺体の端部を確実に保持できるうえ、巻装部の収容容積を大きくして長尺体の収容長さを長くできる、長尺体用スプールを提供することにある。 The technical problem of the present invention is to solve the above-mentioned problems, and the door part can be easily switched between the open position and the closed position, and the end of the elongated body is attached at an arbitrary position by the door part switched to the closed position. An object of the present invention is to provide a spool for a long body that can be reliably held and that can increase the accommodation volume of a long body by increasing the accommodation volume of a winding part.

本発明は上記の課題を解決するために、例えば、本発明の実施の形態を示す図１から図６に基づいて説明すると、次のように構成したものである。
即ち本発明は長尺体用スプールに関し、円筒状に形成された胴部(２)と、この胴部(２)の両側端から径方向外側へ延設した一対のフランジ部(３)とを備え、長尺体(４)が巻回される巻装部(５)をこの両フランジ部(３)間で上記の胴部(２)の周囲に形成した長尺体用スプールであって、少なくとも一方のフランジ部(３)の外周縁部(６)に環状の扉部(７)を延設し、この扉部(７)の基端側に薄肉の凹溝部(８)を環状に形成して、この凹溝部(８)で屈曲させることにより、この扉部(７)の先端側を他方のフランジ部(３)側へ変位させた閉じ姿勢(Ｘ)とこの他方のフランジ部(３)から離隔させた開き姿勢(Ｙ)とに切換可能に構成したことを特徴とする。 In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 6 showing an embodiment of the present invention.
That is, the present invention relates to a spool for a long body, and includes a cylindrical body portion (2) and a pair of flange portions (3) extending radially outward from both side ends of the body portion (2). A spool for a long body in which a winding portion (5) around which the long body (4) is wound is formed around the trunk portion (2) between the flange portions (3), An annular door portion (7) is extended to the outer peripheral edge portion (6) of at least one flange portion (3), and a thin concave groove portion (8) is formed annularly on the base end side of the door portion (7). Then, by bending at the concave groove portion (8), the closed posture (X) in which the front end side of the door portion (7) is displaced toward the other flange portion (3) side and the other flange portion (3 It is characterized in that it can be switched to an open posture (Y) separated from ().

上記の凹溝部は、上記のフランジ部や扉部に比べて薄肉に形成されるので、あたかもヒンジのように容易に屈曲でき、この凹溝部で屈曲させることで、上記の扉部が上記の閉じ姿勢と開き姿勢とに切換えられる。このとき、上記の扉部は上記の凹溝部を屈曲することで姿勢が切換えられるので、この扉部を薄肉に形成する必要がない。即ち、この扉部の肉厚は、例えばこの扉部を延設した上記のフランジ部の肉厚の７０％以上に、より好ましくは７５％以上にすることができ、この結果、閉じ姿勢に切換えた扉部の先端側周縁部は、簡単に変形することなく所定の位置に保持される。 Since the concave groove portion is formed thinner than the flange portion and the door portion, the concave groove portion can be bent easily like a hinge, and by bending the concave groove portion, the door portion is closed. Switching between posture and open posture. At this time, since the posture of the door portion is switched by bending the concave groove portion, it is not necessary to form the door portion thinly. That is, the wall thickness of the door portion can be, for example, 70% or more, more preferably 75% or more of the thickness of the flange portion where the door portion is extended. The peripheral edge on the front end side of the door is held at a predetermined position without being easily deformed.

また上記の扉部は薄肉に形成する必要がないので、長尺体を確りと保持するために湾曲させる必要がない。例えばこの扉部は、上記のフランジ部の中心軸心を中心軸とする截頭円錐面に形成すること、即ち、軸心方向の断面形状が、フランジ部の径方向に対し傾斜した直線状に形成することができる。この結果、フランジ部の径方向に対する扉部の傾斜角度は、径方向の全幅に亘って大きな角度に設定され、これによりこの扉部は、フランジ部の半径方向の寸法が短くされる。 In addition, since the door portion does not need to be formed thin, it is not necessary to bend it in order to securely hold the long body. For example, the door portion is formed in a truncated conical surface with the central axis of the flange portion as a central axis, that is, the axial cross-sectional shape is a straight line inclined with respect to the radial direction of the flange portion. Can be formed. As a result, the inclination angle of the door portion with respect to the radial direction of the flange portion is set to a large angle over the entire width in the radial direction, whereby the radial dimension of the flange portion is shortened in this door portion.

ここで、上記の長尺体とは、上記の胴部へ捲回可能な糸条体や帯状体をいう。この糸条体とは、例えば釣糸や手芸糸などの繊維製品のほか、金属線などをも含む。また上記の帯状体とは、装飾や包装などに用いられるリボン、テープなどをいう。これらの長尺体は、太さや幅は特定の寸法のものに限定されず、合成樹脂製のほか天然繊維製や金属製、紙製などであってもよく、特定の材質に限定されない。 Here, said long body means the thread body and strip | belt-shaped body which can be wound to said trunk | drum. The thread body includes, for example, a metal wire in addition to a textile product such as fishing line or handicraft thread. Moreover, said strip | belt body means the ribbon, tape, etc. which are used for decoration or packaging. These long bodies are not limited to those having specific dimensions in thickness and width, but may be made of synthetic resin, natural fiber, metal, paper, and the like, and are not limited to specific materials.

また上記の胴部やフランジ部は特定の材質に限定されないが、通常、好ましくは合成樹脂材料で形成される。一方、上記の扉部は、上記の閉じ姿勢と開き姿勢とに切換できる程度の柔軟性を備えた材質で形成され、通常、好ましくは合成樹脂材料で形成される。この扉部と上記のフランジ部とは、別体に形成して互いに接着などにより接合してもよいが、例えば合成樹脂材料により一体的に成形すると、接合手段や接合工程が不要であり、安価に実施できて好ましい。 Moreover, although the said trunk | drum part and a flange part are not limited to a specific material, Usually, Preferably it is formed with a synthetic resin material. On the other hand, the door portion is formed of a material having flexibility that can be switched between the closed posture and the open posture, and is preferably formed of a synthetic resin material. The door portion and the flange portion may be formed separately and bonded together by bonding or the like. However, if the door portion and the flange portion are integrally formed with a synthetic resin material, for example, a bonding means and a bonding step are unnecessary, and the cost is low. It is preferable to be able to implement.

上記の扉部は、上記の両フランジ部の外周縁部にそれぞれ延設してもよいが、一方のフランジ部にのみ延設してもよい。即ち、一方のフランジ部を他方のフランジ部よりも大径に形成するとともに、小径のフランジ部の外周縁部に上記の扉部を形成し、上記の閉じ姿勢に切換えたこの扉部が上記の大径フランジ部の外周縁部へ当接するように構成することができる。
この構成によれば、上記の大径フランジ部は外周縁部が真円形など所定形状に保持されているので、閉じ姿勢に切換えた扉部は、このフランジ部に当接することでその外周縁部の形状に沿うこととなる。この結果、閉じ姿勢に切換えた扉部とこれが当接するフランジ部との間に隙間を生じる虞がなく、この閉じ姿勢に切換えた扉部で長尺体の端部を一層確実に保持することができる。 Said door part may be extended in the outer-periphery edge part of said both flange parts, respectively, but you may extend only in one flange part. That is, one flange portion is formed to have a larger diameter than the other flange portion, and the door portion is formed on the outer peripheral edge portion of the small diameter flange portion. It can comprise so that it may contact | abut to the outer-periphery edge part of a large diameter flange part.
According to this configuration, the outer peripheral edge portion of the large-diameter flange portion is held in a predetermined shape such as a perfect circle. Therefore, the door portion that is switched to the closed position is brought into contact with the flange portion so that the outer peripheral edge portion is in contact with the flange portion. It will be along the shape. As a result, there is no possibility of generating a gap between the door portion switched to the closed posture and the flange portion with which the door abuts, and the end portion of the long body can be more securely held by the door portion switched to the closed posture. it can.

この場合、上記の大径フランジ部の外周縁部を薄肉に形成して、上記の閉じ姿勢に切換えた扉部がこの薄肉外周縁部へ当接するように構成すると、この薄肉外周縁部で扉部の押圧力を緩衝し、この薄肉外周縁部を扉部へ沿わせることができるので、扉部とこの薄肉周縁部との間に隙間を生じる虞を一層低減でき、閉じ姿勢に切換えた扉部で長尺体の端部を一層確実に保持することができて好ましい。 In this case, if the outer peripheral edge portion of the large-diameter flange portion is thinly formed and the door portion switched to the closed position is configured to come into contact with the thin outer peripheral edge portion, the door is formed at the thin outer peripheral edge portion. Since the outer peripheral edge of the thin wall can be made to follow the door part, the risk of creating a gap between the door part and the thin peripheral edge can be further reduced, and the door is switched to the closed position. This is preferable because the end of the elongated body can be more reliably held by the portion.

上記の大径フランジ部の外径は、その外周縁部が上記の閉じ姿勢に切換えた扉部へ単に当接する大きさよりもやや大径に形成して、上記の扉部をこの大径フランジ部の外周縁部へ押圧するように当接させると、両者間で上記の長尺体の端部を一層確りと保持することができて好ましい。 The outer diameter of the large-diameter flange portion is formed to have a slightly larger diameter than the size of the outer peripheral edge simply contacting the door portion switched to the closed position, and the door portion is formed into the large-diameter flange portion. It is preferable to make contact with the outer peripheral edge portion so as to be able to hold the end portion of the elongated body more securely between the two.

本発明は上記のように構成され作用することから、次の効果を奏する。 Since the present invention is configured and operates as described above, the following effects can be obtained.

(１)上記の扉部は、上記の凹溝部で屈曲させることで、容易に開き姿勢と閉じ姿勢とに切換えることができる。 (1) The door portion can be easily switched between an open posture and a closed posture by being bent at the concave groove portion.

(２)扉部は上記の凹溝部を屈曲することで姿勢が切換えられるので、この扉部を薄肉に形成する必要がない。この結果、この扉部を厚肉に形成できるので、閉じ姿勢に切換えたこの扉部の先端側周縁部を所定の位置に容易に保持でき、この扉部により任意の位置で長尺体の端部を確実に保持することができる。 (2) Since the posture of the door portion is switched by bending the concave groove portion, it is not necessary to form the door portion thinly. As a result, since the door portion can be formed thick, the front edge side peripheral portion of the door portion switched to the closed posture can be easily held at a predetermined position, and the end of the elongated body can be held at an arbitrary position by the door portion. The part can be securely held.

(３)上記の扉部は薄肉に形成する必要がないので、長尺体を確りと保持するために湾曲させる必要がない。この結果、フランジ部の径方向に対する扉部の傾斜角度を、径方向の全幅に亘って大きな角度に設定することができ、この扉部におけるフランジ部の半径方向の寸法を短くできるので、巻装部の収容容積を大きくして長尺体の収容長さを長くすることができる。 (3) Since the above door portion does not need to be formed thin, it is not necessary to bend it in order to hold the long body securely. As a result, the inclination angle of the door portion with respect to the radial direction of the flange portion can be set to a large angle over the entire width in the radial direction, and the radial dimension of the flange portion in the door portion can be shortened. The accommodation volume of the part can be increased to increase the accommodation length of the elongated body.

以下、本発明の実施の形態を図面に基づき説明する。
図１から図３は本発明の第１実施形態を示し、図１は長尺体用スプールである釣糸用スプールの一部破断斜視図、図２は扉部を閉じ姿勢に切換えた状態の釣糸用スプールの断面図、図３は扉部を開き姿勢に切換えた釣糸用スプールの要部の拡大断面図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a first embodiment of the present invention. FIG. 1 is a partially broken perspective view of a fishing line spool, which is a long body spool, and FIG. 2 is a fishing line in a state where a door is closed and switched to a posture. FIG. 3 is an enlarged cross-sectional view of the main part of the fishing line spool with the door portion opened and switched to the posture.

図１と図２に示すように、この釣糸用スプール(１)は円筒状に形成された胴部(２)と、この胴部(２)の両側端から径方向外側へ延設した一対のフランジ部(３)とを備え、この両フランジ部(３)間で上記の胴部(２)の周囲に、釣糸(４)が巻回される巻装部(５)を形成してある。 As shown in FIGS. 1 and 2, the fishing line spool (1) has a cylindrical body (2) and a pair of radially extending outer ends from both ends of the body (2). A winding portion (5) around which the fishing line (4) is wound is formed around the trunk portion (2) between the flange portions (3).

上記のフランジ部(３)は、一方のフランジ部(3a)を他方のフランジ部(3b)よりも大径に形成してあり、この小径フランジ部(3b)の外周縁部(6b)に、環状の扉部(７)が延設してある。この扉部(７)と上記の両フランジ部(３)と胴部(２)とは、ポリエチレン樹脂やポリプロピレン樹脂などの合成樹脂材料で一体に成形してあり、扉部(７)の肉厚は、小径フランジ部(3b)の肉厚の７０％以上に、好ましくは７５％以上に形成してある。 In the flange portion (3), one flange portion (3a) has a larger diameter than the other flange portion (3b), and the outer peripheral edge portion (6b) of the small diameter flange portion (3b) An annular door (7) is extended. The door portion (7), the flange portions (3) and the body portion (2) are integrally formed of a synthetic resin material such as polyethylene resin or polypropylene resin, and the thickness of the door portion (7) is increased. Is formed to be 70% or more, preferably 75% or more of the thickness of the small diameter flange portion (3b).

上記の扉部(７)は、フランジ部(３)の中心軸心(Ｌ)を中心軸とする截頭円錐面に形成してあり、従って図２に示すように、軸心方向の断面形状が、フランジ部(３)の径方向に対し傾斜した直線状に形成されている。このため、上記のフランジ部(３)の径方向に対する扉部(７)の傾斜角度を、径方向の全幅に亘って大きな角度に、例えば約４５度に設定することができ、この扉部(７)におけるフランジ部(３)の半径方向の寸法を短くして、巻装部(５)の収容容積を大きくすることができる。 Said door part (7) is formed in the frusto-conical surface which makes the central axis (L) of a flange part (3) a center axis, Therefore, as shown in FIG. Is formed in a linear shape inclined with respect to the radial direction of the flange portion (3). For this reason, the inclination angle of the door portion (7) with respect to the radial direction of the flange portion (3) can be set to a large angle over the entire width in the radial direction, for example, about 45 degrees. The dimension of the flange portion (3) in the radial direction in 7) can be shortened, and the accommodation volume of the winding portion (5) can be increased.

上記の扉部(７)の基端側には薄肉の凹溝部(８)が環状に形成してある。この凹溝部(８)は上記の小径フランジ部(3b)や扉部(７)に比べて薄肉に形成されているので、あたかもヒンジのように屈曲することができる。従って図３に示すように、この凹溝部(８)で屈曲させることにより、上記の扉部(７)は、先端側を大径フランジ部(3a)側へ変位させた閉じ姿勢(Ｘ)とこの大径フランジ部(3a)から離隔させた開き姿勢(Ｙ)とに切換られる。なお、本発明における上記の凹溝部(８)の断面形状は特定の形状に限定されず、底の浅いＵ字形や半円形など、任意の形状に形成することができる。 A thin groove portion (8) is formed in an annular shape on the base end side of the door portion (7). Since the concave groove (8) is formed thinner than the small-diameter flange (3b) and the door (7), it can be bent as if it were a hinge. Therefore, as shown in FIG. 3, by bending the groove (8), the door (7) has a closed posture (X) in which the distal end is displaced toward the large-diameter flange (3a). It is switched to an open posture (Y) separated from the large diameter flange portion (3a). In addition, the cross-sectional shape of the concave groove portion (8) in the present invention is not limited to a specific shape, and can be formed in an arbitrary shape such as a shallow U-shape or semicircular shape.

上記の大径フランジ部(3a)は、外周縁部(6a)が薄肉に形成してあり、この薄肉外周縁部(6a)の外径は、上記の閉じ姿勢(Ｘ)に切換えた扉部(７)へ単に当接する大きさよりもやや大径に形成してある。一方、上記の扉部(７)の外径は、上記の大径フランジ部(3a)の外径よりも大径に形成してある。このため、上記の閉じ姿勢(Ｘ)に切換えた扉部(７)は、大径フランジ部(3a)を包み込むように取り囲み、その先端周縁(９)から内方へ入り込んだ位置で、上記の大径フランジ部(3a)の外周縁部(6a)へ押付けるように当接する。このときの押圧力は、上記の外周縁部(6a)が薄肉であるので良好に緩衝される。この結果、この閉じ姿勢(Ｘ)に切換えた扉部(７)は、大径フランジ部(3a)の薄肉外周縁部(6a)に沿った形状となり、この薄肉外周縁部(6a)との間に隙間を生じることなく、均一に押し付けた状態で当接する。 The large-diameter flange portion (3a) has a thin outer peripheral edge portion (6a), and the outer diameter of the thin outer peripheral edge portion (6a) is the door portion switched to the closed position (X). It is formed to have a diameter slightly larger than the size that simply contacts with (7). On the other hand, the outer diameter of the door portion (7) is formed larger than the outer diameter of the large-diameter flange portion (3a). For this reason, the door portion (7) switched to the closed posture (X) surrounds the large-diameter flange portion (3a) so as to wrap around and enters the above-mentioned peripheral edge (9) inward from the above-described position. It abuts against the outer peripheral edge (6a) of the large diameter flange (3a). The pressing force at this time is satisfactorily buffered because the outer peripheral edge (6a) is thin. As a result, the door portion (7) switched to the closed posture (X) has a shape along the thin outer peripheral edge portion (6a) of the large diameter flange portion (3a). It abuts in a state of being pressed evenly without generating a gap therebetween.

上記の扉部(７)の肉厚は、小径フランジ部(3b)の肉厚の７０％以上に、好ましくは７５％以上に形成されており、大径フランジ部(3a)の薄肉外周縁部(6a)へ確りと、周方向の全域にわたって均一に押付けられる。この結果、釣糸(４)の端部が巻装部(５)の周方向のいずれの位置にあっても、図２に示すように、この閉じ姿勢(Ｘ)に切換えた扉部(７)と大径フランジ部(3a)との間の任意の位置で、この釣糸(４)の端部を確実に保持することができる。 The thickness of the door part (7) is 70% or more, preferably 75% or more of the thickness of the small diameter flange part (3b), and the thin outer peripheral edge part of the large diameter flange part (3a). It is surely pressed to (6a) and evenly pressed over the entire circumferential direction. As a result, regardless of the position of the end of the fishing line (4) in the circumferential direction of the winding part (5), as shown in FIG. 2, the door part (7) switched to this closed position (X). The end portion of the fishing line (4) can be securely held at an arbitrary position between the large diameter flange portion (3a).

また上記の閉じ姿勢(Ｘ)に切換えた扉部(７)の先端周縁(９)は、大径フランジ部(3a)との当接位置よりも外方へ突出した状態となっている。このため、作業者はこの突出した部分に指先を引っ掛ける等により、扉部(７)を大径フランジ部(3a)から簡単に分離でき、上記の凹溝部(８)で屈曲させることで、この扉部(７)を開き姿勢(Ｙ)へ容易に切換えることができる。 Moreover, the front-end | tip periphery (9) of the door part (7) switched to said closing attitude | position (X) is the state which protruded outward rather than the contact position with a large diameter flange part (3a). For this reason, the operator can easily separate the door portion (7) from the large-diameter flange portion (3a) by hooking a fingertip on the protruding portion, and by bending the groove portion (8), The door (7) can be easily switched to the open position (Y).

上記の第１実施形態では、上記の凹溝部(８)を扉部(７)の基端側の外面に形成した。しかし本発明はこの凹溝部(８)を扉部(７)の基端側のいずれの面に形成してもよい。
即ち、図４に示す変形例１では、凹溝部(８)を、扉部(７)の基端側の、巻装部(５)に臨む内面に形成したものである。また、図５に示す変形例２では、凹溝部(８)を、扉部(７)の基端側の、外面と内面との両面に形成したものである。 In said 1st Embodiment, said recessed groove part (8) was formed in the outer surface of the base end side of a door part (7). However, in the present invention, the concave groove portion (8) may be formed on any surface on the base end side of the door portion (7).
That is, in the modification 1 shown in FIG. 4, the groove part (8) is formed in the inner surface which faces the winding part (5) of the base end side of a door part (7). Moreover, in the modification 2 shown in FIG. 5, the groove part (8) is formed in both the outer surface and the inner surface of the base end side of a door part (7).

図６は本発明の第２実施形態を示す、扉部を閉じ姿勢に切換えた状態の釣糸用スプールの要部の拡大断面図である。 FIG. 6 is an enlarged cross-sectional view of a main portion of a fishing line spool in a state in which the door portion is closed and switched to a posture, showing a second embodiment of the present invention.

この第２実施形態では、第１実施形態と同様に、円筒状に形成された胴部(２)と、この胴部(２)の両側端から径方向外側へ延設した一対のフランジ部(３)とを備え、釣糸(４)が巻回される巻装部(５)を、この両フランジ部(３)間で上記の胴部(２)の周囲に形成してあるが、第１実施形態と異なり、上記の両フランジ部(３)の外周縁部(６)にそれぞれ環状の扉部(７)が延設してある。なお、上記の胴部(２)とフランジ部(３)と扉部(７)は、上記の第１実施形態と同様、合成樹脂材料で一体に形成してあり、扉部(７)の肉厚は、フランジ部(３)の肉厚の７０％以上に、好ましくは７５％以上に形成してある。また扉部(７)は、フランジ部(３)の中心軸心を中心軸とする截頭円錐面に形成してある。 In the second embodiment, similarly to the first embodiment, a cylindrically formed body part (2) and a pair of flange parts (2) extending radially outward from both side ends of the body part (2) ( 3), and a winding portion (5) around which the fishing line (4) is wound is formed around the trunk portion (2) between the flange portions (3). Unlike the embodiment, an annular door portion (7) extends from the outer peripheral edge portion (6) of both flange portions (3). In addition, said trunk | drum (2), flange part (3), and door part (7) are integrally formed with the synthetic resin material similarly to said 1st Embodiment, The meat | flesh of door part (7) is formed. The thickness is 70% or more, preferably 75% or more of the thickness of the flange portion (3). Moreover, the door part (7) is formed in the frusto-conical surface which makes the central axis the center axis of the flange part (3).

上記の各扉部(７)は基端側に薄肉の凹溝部(８)が環状に形成してあり、この凹溝部(８)をヒンジのように屈曲させることで、それぞれ扉部(７)の先端側を他方のフランジ部(３)側へ変位させた閉じ姿勢(Ｘ)とこの他方のフランジ部(３)から離隔させた開き姿勢(Ｙ)とに切換可能に構成してある。 Each of the door portions (7) has a thin groove portion (8) formed in an annular shape on the base end side, and each of the door portions (7) is bent by bending the groove portion (8) like a hinge. It is configured to be switchable between a closed posture (X) in which the tip end side is displaced toward the other flange portion (3) and an open posture (Y) separated from the other flange portion (3).

上記の両扉部(７)は、その外径(D1・D2)を互いに異ならせてあり、大径扉部(7a)と小径扉部(7b)とから構成してある。そして両扉部(７)をそれぞれ閉じ姿勢(Ｘ)に切換えると、大径扉部(7a)は小径扉部(7b)の先端周縁(9b)を包み込むように取り囲み、この大径扉部(7a)の先端周縁(9a)から内方へ入り込んだ位置で、小径扉部(7b)の先端周縁(9b)と当接するように構成してある。一方、上記の小径扉部(7b)の外径(D2)は、その先端周縁(9b)が上記の閉じ姿勢(Ｘ)に切換えた大径扉部(7a)へ単に当接する大きさよりもやや大径に形成してあり、従って、大径扉部(7a)はこの小径扉部(7b)へ押付けられるように当接する。この結果、両扉部(7a・7b)は、両者間に隙間を生じることなく、均一に押付けた状態で互いに当接する。 The two door portions (7) have different outer diameters (D1, D2), and are composed of a large-diameter door portion (7a) and a small-diameter door portion (7b). When the doors (7) are respectively switched to the closed position (X), the large-diameter door (7a) surrounds the peripheral edge (9b) of the small-diameter door (7b), and the large-diameter door ( 7a) is configured to come into contact with the front end periphery (9b) of the small-diameter door portion (7b) at a position entering inward from the front end periphery (9a). On the other hand, the outer diameter (D2) of the small-diameter door portion (7b) is slightly larger than the size in which the peripheral edge (9b) is simply in contact with the large-diameter door portion (7a) switched to the closed position (X). The large-diameter door portion (7a) comes into contact with the small-diameter door portion (7b) so as to be pressed against the small-diameter door portion (7b). As a result, the door portions (7a, 7b) abut against each other in a state where they are uniformly pressed without causing a gap therebetween.

また大径扉部(7a)の先端周縁(9a)は、小径扉部(7b)の先端周縁(9b)から外方へ突出しており、作業者はこの突出した部分に指先等を引っ掛けるなどして、大径扉部(7a)を小径扉部(7b)から簡単に分離させて開き姿勢(Ｙ)へ切換えることができる。 In addition, the peripheral edge (9a) of the large-diameter door (7a) protrudes outward from the peripheral edge (9b) of the small-diameter door (7b), and the operator hooks a fingertip or the like on the protruding part. Thus, the large-diameter door portion (7a) can be easily separated from the small-diameter door portion (7b) and switched to the open posture (Y).

上記の実施形態で説明した長尺体用スプールは、本発明の技術的思想を具体化するために例示したものであり、各部の形状や寸法、材質などをこの実施形態のものに限定するものではなく、本発明の特許請求の範囲内において種々の変更を加え得るものである。 The long body spool described in the above embodiment is exemplified to embody the technical idea of the present invention, and the shape, dimensions, material, and the like of each part are limited to those of this embodiment. Rather, various modifications can be made within the scope of the claims of the present invention.

例えば、上記の各実施形態では胴部とフランジ部と扉部を合成樹脂材料で一体に形成したので、安価に製造することができる。しかし本発明では、例えば胴部とフランジ部とを別体に形成して組み付けるものであってもよい。また、上記の各実施形態では扉部を截頭円錐面に形成したが、本発明の上記の扉部は、湾曲させた形状であってもよい。 For example, in each of the above embodiments, the body portion, the flange portion, and the door portion are integrally formed of a synthetic resin material, and therefore can be manufactured at low cost. However, in the present invention, for example, the body portion and the flange portion may be formed separately and assembled. Moreover, in each said embodiment, although the door part was formed in the truncated cone surface, the curved shape may be sufficient as said door part of this invention.

さらに、上記の実施形態では長尺体が釣糸である場合について説明したが、本発明に用いる上記の長尺体は、他の糸条体や、巻装部と同じ幅の或いはこれよりも狭い幅の帯状体等であってもよいことは、言うまでもない。 Furthermore, in the above embodiment, the case where the long body is a fishing line has been described. However, the above long body used in the present invention has the same width as or narrower than other thread bodies and winding parts. Needless to say, it may be a band or the like having a width.

本発明の長尺体用スプールは、扉部を容易に開き姿勢と閉じ姿勢とに切換でき、閉じ姿勢に切換えた扉部で長尺体の端部を確実に保持できるうえ、巻装部の収容容積を大きくして長尺体の収容長さを長くできるので、特に釣糸用スプールに好適であるが、手芸糸や包装用テープなど、他の長尺体に用いるスプールにも好適である。 The spool for the long body of the present invention can easily switch the door portion between the open posture and the closed posture, and can securely hold the end of the long body with the door portion switched to the closed posture. Since the accommodation volume can be increased and the accommodation length of the long body can be increased, it is particularly suitable for a spool for fishing line, but is also suitable for a spool used for other long bodies such as handicraft yarn and packaging tape.
