Description

  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 present invention relates to a spool for a long body that can easily switch a door portion between an open posture and a closed posture, and can reliably hold an end portion of the long body at an arbitrary position by the door portion switched to the closed posture.

  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).

  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.

  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.

JP 2002-153189 A Japanese Patent No. 3878196

  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.

  However, 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, some of them may be displaced from each other in the radial direction. And when such a shift | offset | difference arises, a clearance gap will be produced between both door parts, and there exists a problem which becomes impossible to clamp said elongate body in the part.

  Moreover, since both said door parts hold | grip said elongate body by mutually abutting and pressing the clamping board provided at the front-end | tip, respectively, the outer diameter of this clamping board is formed in the same magnitude | size. For this reason, when switching the door part to the open position, such as when quickly rewinding a long body that has been drawn out long, it is difficult to separate one door part from the other door part. There is a problem that cannot be switched easily.

  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 long body spool that can be reliably held.

In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 3 showing an embodiment of the present invention.
That is, the present invention relates to a spool for a long body, and a cylindrical body portion (2) and a pair of flange portions (3) extending radially outward from both 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 body portion (2) between the flange portions (3). One flange portion (3a) is formed to have a larger diameter than the other flange portion (3b), and an annular door portion (7) is extended to the outer peripheral edge portion (6b) of the small diameter flange portion (3b). Then, switching between the closed position (X) in which the front end side of the door (7) is displaced toward the large diameter flange (3a) and the open position (Y) separated from the large diameter flange (3a) The outer peripheral edge portion (6a) of the large-diameter flange portion (3a) is formed thin, and the outer diameter of the door portion (7) is set outside the large-diameter flange portion (3a). Form larger than the diameter and switch to the above closed position (X) Door portion (7), characterized by being configured to abut from the tip periphery (9) the thin outer peripheral edge portion of the large-diameter flange portion at a position entered inwardly (3a) to (6a) .

As a reference invention, regarding a long body spool, 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). The annular door portion (7) is extended to the outer peripheral edge portion (6) of both flange portions (3), and the front end side of the door portion (7) is directed to the other flange portion (3) side. It is configured to be switchable between a displaced closed position (X) and an open position (Y) separated from the other flange part (3), and both the door parts (7) have an outer diameter (D1 · D2) is made different from each other, and is composed of a large-diameter door portion (7a) and a small-diameter door portion (7b). 9a) Changed to the above closed position (X) at the position entering inward from It is conceivable that the small-diameter door portion (7b) is configured to come into contact with the leading edge (9b) .

  In the first aspect of the present invention, when the door portion is switched to the closed position, the door portion surrounds the large-diameter flange portion so as to enclose the large-diameter flange portion inward from the peripheral edge of the tip to the outer peripheral edge portion of the large-diameter flange portion. Abut. As a result, the door portion switched to this closed position has a shape along the outer peripheral edge of the large-diameter flange portion, and is in contact with the large-diameter flange portion uniformly without any gap, and is long between the two. The scale is securely held. And since the peripheral edge of the door portion protrudes outward from the outer peripheral edge portion of the large-diameter flange portion, the door portion in the closed position is placed on the protruding peripheral edge of the finger by the operator. It can be easily separated from the flange by hooking and switched to the open position.

In the above reference invention , the large-diameter door portion surrounds the small-diameter door portion so as to enclose the small-diameter door portion when switched to the closed position, and the small-diameter door portion is located inward from the peripheral edge of the large-diameter door portion. It abuts on the tip periphery. As a result, the large-diameter door portion switched to this closed position has a shape along the periphery of the tip of the small-diameter door portion, and is in uniform contact with the small-diameter door portion without any gap between the two door portions. The long body is securely held. Since the leading edge of the large-diameter door part protrudes outward from the leading edge of the small-diameter door part, the large-diameter door part in a closed position is placed on the protruding tip edge of the fingertip by the operator. It can be easily separated from the small-diameter door portion by hooking, etc., and switched to the open posture. Further, when the large-diameter door portion is switched to the open posture, the small-diameter door portion is easily switched to the open posture by pressing the peripheral edge of the tip outward.

  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.

  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.

  When the above-mentioned door part is formed with a thin groove groove on the base end side in an annular shape, the door part can be easily switched between a closed position and an open position by bending the groove part like a hinge. This is preferable. The shape of the door portion is not limited to a specific shape, and may be curved outward, for example, but if it is formed on a frustoconical surface with the central axis of the flange portion as the central axis, that is, in the axial direction When the cross-sectional shape is formed in a straight line inclined with respect to the radial direction of the flange portion, it is preferable because a large accommodation volume of the winding portion can be secured.

In the present invention 1 described above, the large-diameter flange portion is formed such that the outer peripheral edge portion is formed thin, and the door portion switched to the closed posture is in contact with the thin outer peripheral edge portion . The possibility of creating a gap between the door portion and the thin peripheral edge portion can be further reduced, and the end portion of the long body can be more reliably held by the door portion switched to the closed posture .

  Further, in the present invention 1, when the outer diameter of the large-diameter flange portion is formed to be slightly larger than the size where the outer peripheral edge portion simply contacts the door portion switched to the closed position, the door portion is formed. This can be brought into contact with the outer peripheral edge portion of the large-diameter flange portion so that the end portion of the long body can be more securely held between them.

Similarly, in the above reference invention , when the outer diameter of the small-diameter door portion is formed to be slightly larger than the size in which the peripheral edge of the small-diameter door simply contacts the large-diameter door portion switched to the closed position, the large diameter The door part can be brought into contact so as to press against the peripheral edge of the small-diameter door part, and the end part of the long body can be more securely held between both door parts.

  Since the present invention is configured and operates as described above, the following effects can be obtained.

  (1) In the first aspect of the present invention, the door portion switched to the closed position surrounds the large-diameter flange portion so as to wrap around the outer peripheral edge of the large-diameter flange portion. It can be made to contact uniformly, without producing a gap between them. As a result, even if the end of the elongated body is in any of the circumferential directions of the winding part, the end of the elongated body is moved at an arbitrary position between the door portion and the flange portion switched to this closed position. It can be held securely.

  (2) Since the leading edge of the door is in a state of protruding outward from the outer peripheral edge of the large-diameter flange, the door is moved by the operator hooking a fingertip or the like on the protruding leading edge. The part can be easily separated from the flange part and switched to the open position.

(3) In the above-described reference invention , the large-diameter door portion switched to the closed posture surrounds the front-end periphery of the small-diameter door portion, and has a shape along the front-end periphery of the small-diameter door portion. It can be made to contact | abut uniformly, without producing a clearance gap between small diameter door parts. As a result, the end of the long body can be reliably held between the door portions that are switched to the closed position regardless of the end of the long body in the circumferential direction of the winding portion.

  (4) Since the leading edge of the large-diameter door portion protrudes outward from the leading edge of the small-diameter door portion, the operator hooks a fingertip or the like on the protruding leading edge of the large-diameter door portion. Can be easily separated from the small-diameter door portion and switched to the open posture.When the large-diameter door portion is switched to the open posture, the small-diameter door portion can be easily pressed by pushing the peripheral edge of the tip outward. It can be switched to the open position.

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.

  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).

  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).

  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.

  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). Note that the cross-sectional shape of the concave groove portion (8) is not limited to a specific shape, and can be formed in an arbitrary shape such as a shallow U-shape or semicircular shape. Further, the recessed groove portion (8) may be formed on either the outer surface or the inner surface on the base end side of the door portion (7), or may be formed on both surfaces.

  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.

  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).

  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).

FIG. 4 is an enlarged cross-sectional view of the main part of the fishing line spool in a state in which the door portion is closed and switched to the posture, showing an embodiment of the reference invention .

In the embodiment of this reference invention , as in the first embodiment, a cylindrical body portion (2) and a pair of flange portions extending radially outward from both side ends of the body portion (2) (3), and a winding part (5) around which the fishing line (4) is wound is formed around the trunk part (2) between the two flange parts (3). Unlike 1 embodiment, the annular door part (7) is each extended in the outer-periphery edge part (6) of both said flange parts (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).

  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).

  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.

  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).

  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.

  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.

  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.

  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.

It is a partially broken perspective view of a spool for fishing line showing a first embodiment of the present invention. It is sectional drawing of the spool for fishing lines of the state which closed the door part and switched to the attitude | position of 1st Embodiment. It is an expanded sectional view of the principal part of the spool for fishing lines which changed the door part into the open attitude | position of 1st Embodiment.
