Description

  The present invention is a spool around which strips such as fishing line, handicraft thread, metal wire, etc., as well as wrapping tape, etc. are wound, and the required amount can be drawn out at any time. The spool for a long body provided with a door portion for holding an end portion, and more specifically, a long portion in which the flange portion can be easily enlarged and the end portion of the long body can be securely held by the door portion. It relates to a body spool.

  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 problems, conventionally, a door portion is formed on each of the outer peripheral edge portions of the two flange portions, and the outer peripheral edge portions of the two door portions are closed to be close to each other and opened to be separated from each other. A spool configured to be switchable 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

  The above-mentioned spool has a large diameter flange portion, and if it is intended to increase the capacity of the long body, the mold becomes large and cannot be implemented at low cost, and the flange portion is formed thin. When the diameter of the thin flange portion is increased, it is difficult for the synthetic resin to sufficiently reach the tip during molding, and it is not easy to perform integral molding by injection molding or the like.

  In order to solve the above problems, the first spool portion including one flange portion and the second spool portion including the other flange portion may be formed separately from each other, and the two spool portions may be connected to each other. Conceivable. However, when a long body is wound around the winding portion of the spool, pressure is applied to the inner surfaces of the two flange portions in the direction of widening the flange interval, so that the flange portions are formed in different spool portions as described above. In such a case, the door portion formed on the outer peripheral edge of the flange portion may be retracted from the other flange portion and cannot be brought into contact with the other door portion. In particular, when the diameter of the flange portion is increased, the door portion formed on the outer peripheral edge of the flange portion is greatly retracted, and the door portions are more easily separated. There was a problem that the end could not be clamped.

  The technical problem of the present invention is to provide a long body spool that solves the above-mentioned problems, facilitates the enlargement of the flange portion, and can securely hold the end of the long body by the door portion. There is to do.

In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 8 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 winding portion (4) around which the long body (5) is wound is formed around the body portion (2) between the flange portions (3), and at least one flange portion (3) An elongated door portion (10) is formed on the outer peripheral edge of the long body spool, and the distal end side of the door portion (10) is displaced to the other flange portion (3) side. A first spool portion (1a) including one flange portion (3) and a second spool portion (1b) including the other flange portion (3) are formed separately from each other, and both spool portions ( 1a and 1b) are connected to each other, at least the first spool portion (1a) is formed of a flexible material, and the front end of the door portion (10) is brought into contact with the other flange portion (3). Extending outside the contact position Te, characterized in that in contact so as to press the door portion (10) the flange portion of the other side to (3).

  The door formed on the outer peripheral edge of the one flange is in contact with the other flange at a position displaced inward from the tip, but the first spool portion including the flange Is made of a soft material, the door portion is elastically deformed to abut against the other flange portion with a predetermined pressing force. When the long body is wound around the winding portion, the two flange portions are pressed by the long body and are subjected to pressure in the direction of widening the flange interval, so that the door portion retreats from the other flange portion. And However, since the front end of the door portion extends outward from the contact position with the other flange portion, even if the flange interval is increased by being pressed by the long body, the door portion is It is maintained in contact with the other flange portion.

  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 fibers, metal, paper, and the like, and are not limited to specific materials.

  Examples of the flexible material include polypropylene resin, polyethylene resin, and soft polyvinyl chloride resin. The door portion can be brought into contact with the other flange portion with a predetermined pressing force, and The contact state is not limited to a specific material as long as it is flexible enough to maintain the long body even when it is wound. However, this flexible material needs to have a hardness enough to reliably receive the elongated body to be wound. Specifically, the above-mentioned flexibility is a measurement method defined by, for example, JIS K7215, The durometer hardness (HDD) of D is preferably 30 to 70, more preferably 40 to 60.

  The first spool portion is formed of a flexible material, but the other second spool portion is not limited to a specific material. For example, when the same spool material is formed of the same flexible material, the door portions formed on both spool portions are opened. Switching to the posture is preferable because the winding portion can be greatly opened. However, in general, a soft material has low transparency, and it is not easy to visually observe a long body wound around a winding part. On the other hand, when the second spool portion is formed of a material harder than the first spool portion, such as polystyrene resin or polycarbonate resin, the strength of the entire long body spool can be maintained high. It is preferable because transparency on the two-spool portion side can be easily secured, and the color and size of the long body can be easily observed.

  The barrel portion may be formed on one of the first spool portion and the second spool portion, or may be formed separately from both spool members. It is also possible to connect the first spool portion and the second spool portion via each other. However, if the body is composed of a first body part formed on the first spool part and a second body part formed on the second spool part, the body part is formed in a cylindrical shape. Therefore, it is preferable because it has high rigidity and can be securely connected. In this case, the first body portion is provided with an engaging portion and the second body portion is provided with a locking portion, and the engaging portion is engaged with the engaging portion, thereby the first body portion. It is preferable to connect the portion portion and the second body portion to each other without requiring treatment such as adhesion, so that both the body portions can be easily connected to each other.

  The door portion may be formed on both spool portions, but may be formed only on the first spool portion. That is, a door portion is formed on the outer peripheral edge portion of the one flange portion, the door portion is displaced to the other flange portion side, and is configured to contact the outer peripheral edge portion of the other flange portion. can do. According to this configuration, since the outer peripheral edge portion of the other flange portion is held in a predetermined shape such as a true circle, the door portion in contact with the flange portion follows the shape of the outer peripheral edge portion. There is no possibility of creating a gap between the door portion and the other flange portion with which the door portion abuts, and this door portion can hold the end portion of the long body more reliably.

  The door portion is not limited to a specific shape or structure, but the door portion is separated from the other flange portion with a closed posture in which the distal end side of the door portion is displaced toward the other flange portion side. By switching to the open position, the end of the long body can be securely held by switching the door to the closed position, and the long body can be easily attached to the winding part by switching to the open position. It is preferable because it can be guided and wound.

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

  (1) Since the first spool portion including the one flange portion and the second spool portion including the other flange portion are formed separately from each other and the spool portions are connected to each other, At this time, the synthetic resin can be easily turned to the tip of the thin flange portion, the size of the flange portion can be easily increased, and the capacity of the long body can be easily increased.

  (2) Even if the flange interval is widened by winding the long body around the winding portion, the door portion is maintained in contact with the other flange portion. It is possible to securely hold the end of the.

  (3) Since one of the flanges and the door is made of a flexible material, it can be easily deformed. By separating the door from the other flange, the long body is wound. It can be easily guided to the part and wound around this winding part.

FIG. 3 is a view corresponding to FIG. 2 and showing a third embodiment of the present invention. It is an expanded sectional view of a trunk part neighborhood of a 2nd embodiment.

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 shows a first spool portion and a second spool portion before assembly. FIG. 3A is an enlarged perspective view of the vicinity of the body of the spool portion, FIG. 3A is an enlarged cross-sectional view of the vicinity of the winding portion, and FIG. 3B is an enlarged cross-sectional view of portion B of FIG.

  As shown in FIG. 1, the fishing line spool (1) includes a cylindrical body (2) and a pair of flanges extending radially outward from both ends of the body (2). (3). And the winding part (4) is formed in the circumference | surroundings of said trunk | drum (2) between these both flange parts (3), and a fishing line (5) is wound around this winding part (4). .

  As shown in FIGS. 1 and 2, the fishing line spool (1) includes a first spool portion (1a) including a first flange portion (3a) as one flange portion and the other flange portion. The second spool portion (1b) including the second flange portion (3b) is formed separately from each other, and both spool portions (1a, 1b) are connected to each other by the body portion (2). That is, the body (2) includes a first body part (2a) formed on the first spool part (1a) and a second body part (2b) formed on the second spool part (1b). The first body portion (2a) is provided with a groove-like engaging portion (6), and the second body portion (2b) is provided with a hook-like locking portion (7). It is. By engaging the engaging part (7) with the engaging part (6), the first body part (2a) and the second body part (2b) are connected to each other.

  In the first body portion (2a), an annular convex portion (8) is formed on the periphery of the connection end surface. The second body portion (2b) is formed with an annular recess (9) at a portion facing the annular projection (8). When the first body portion (2a) and the second body portion (2b) are connected to each other, the annular projection (8) and the annular recess (9) are fitted in an inlay manner. As a result, the outer peripheral surface of the body part (2) is formed into a smoothly continuous cylindrical surface so that the fishing line (5) wound around the winding part (4) does not enter between the body parts (2a, 2b). It is.

  Both the first spool portion (1a) and the second spool portion (1b) are made of a flexible synthetic resin material such as polypropylene resin, polyethylene resin, or soft polyvinyl chloride resin. Specifically, for example, a polyethylene resin having a type D durometer hardness (HDD) of about 55 is used.

  As shown in FIGS. 1 and 3, annular door portions (10) are formed on the outer peripheral edge portions of the flange portions (3a, 3b). The front end side of the door portion (10) is displaced to the other flange portion side, and the front end portions of the door portions (10, 10) are brought into contact with each other. Further, the front end of the door portion (10) is in a natural state before the spool portions (1a and 1b) are assembled to each other, as shown by the phantom line in FIG. Is extended outward by a predetermined length (L) from the contact position. By assembling both spool portions (1a, 1b) with each other, the door portions (10) are in contact with each other so as to press each other. At this time, since both the spool portions (1a, 1b) are made of a flexible synthetic resin material, the door portions (10) come into contact with each other with a predetermined pressing force by elastic deformation.

  Further, since both the door portions (10, 10) are made of a flexible synthetic resin material, the front end side of the door portion (10) is arranged on the other side as shown by a solid line in FIG. A closed posture (X) deflected to the door (10) side and an open posture (Y) separated from the other door (10) as shown by the phantom line in FIG. It is possible to switch.

  When the fishing line (5) is wound on the fishing line spool (1), the doors (10, 10) are switched to the open position (Y), and the fishing line (4) is lined with the fishing line (4). Guide 5) and roll. By this winding, the both flange portions (3a, 3b) are each subjected to pressure outward, that is, in a direction of widening the flange interval. However, each of the spool portions (1a, 1b) including the flange portion (3) is made of a flexible synthetic resin material, and the door formed on the outer peripheral edge of each flange portion (3a, 3b). Since the portion (10) is extended outward by a predetermined length (L) from the contact position with the other door portion (10), the flange is caused by the pressing force when the fishing line (5) is wound. Even if the interval is widened, when the doors (10) are switched to the closed position (X), the door (10) is elastically deformed and applied to the other door (10) with a predetermined pressing force. Maintained in contact. As a result, as shown in FIG. 1, the end portion of the fishing line (5) pulled out from the winding portion (4) is securely held between the door portions (10, 10).

  In said embodiment, the shape of the door part was formed in the substantially conical surface, and the front-end | tip parts of both door parts contact | abutted mutually. However, in the present invention, the door portion is not limited to a specific shape, and the contact position between the door portion and another flange portion is not limited to that of the above embodiment.

  For example, in Modification 1 shown in FIG. 4, the door portion (10a) formed on the first flange portion (3a) has a larger diameter than the door portion (10b) formed on the second flange portion (3b). Then, the distal end (11) of the large-diameter door portion (10a) is extended outward from the contact position with the small-diameter door portion (10b), and the distal end (11 of the large-diameter door portion (10a) ) At a position deviated inward from) so as to press against the small-diameter door (10b). With this configuration, when both doors (10a, 10b) are switched to the closed position (X), the large-diameter door (10a) follows the outer peripheral edge of the small-diameter door (10b). Supported. As a result, there is no possibility of creating a gap between the door portions (10a, 10b) over the entire periphery of the flange portion (3), and the fishing line can be held and held at an arbitrary position.

  In the first embodiment, both flange portions are formed of a flexible synthetic resin material. However, in the present invention, the second spool portion (1b) may be formed of a material harder than the first spool portion (1a), for example, as in the second embodiment shown in FIG.

  That is, in the second embodiment, the first spool portion (1a) is formed of a flexible synthetic resin material such as polypropylene resin, as in the first embodiment. However, the second spool portion (1b) is harder than the first spool portion (1a), and is formed of, for example, polystyrene resin or polycarbonate resin. The first spool portion (1a) is formed with an annular door portion (10) on the outer peripheral edge of the first flange portion (3a), and the front end side of the door portion (10) is connected to the second spool portion ( It is displaced to the second flange part (3b) side of 1b). On the other hand, this 2nd spool part (1b) forms the 2nd flange part (3b) in the flat disk shape, and the door part is not formed in the outer periphery part.

  The second spool portion (1b) is made of a hard synthetic resin material and does not contain a plasticizer. Therefore, the second spool portion (1b) can be made of a transparent material so that the inside fishing line can be sufficiently observed. In addition, since the second flange portion (1b) is made of a hard material, the second flange portion (3b) can maintain the rigidity and strength of the entire fishing line spool (1) with a predetermined pressing force. The door part (10) displaced to the second flange part (3b) side can be securely received, and between the door part (10) over the entire periphery of the second flange part (3b). Generation of a gap is prevented. The other configuration is the same as that of the first embodiment described above, and functions in the same manner, so that the description thereof is omitted.

  Also in this 2nd Embodiment, the shape of said door part is not limited to said thing, It can form in arbitrary shapes. For example, in the second modification shown in FIG. 6 (a), the first flange portion (3a) has a larger diameter than the second flange portion (3b), and the outer peripheral edge of the first flange portion (3a). The tip of the door part (10) formed in the part extends outward from the contact position with the second flange part (3b), and is displaced inward from the tip (11) of the door part (10) At this position, the second flange portion (3b) is pressed against the second flange portion (3b). With this configuration, the door (10) switched to the closed position (X) is supported along the outer peripheral edge of the second flange (3b), and the entire peripheral edge of the second flange (3b). Therefore, the possibility of creating a gap between the door portions (10, 10) can be further eliminated, and the fishing line can be pinched and held securely at an arbitrary position.

  In the third modification shown in FIG. 6 (b), an annular door portion (10) is formed on the outer peripheral edge of the second flange portion (3b), and the front end side of the door portion (10) is the first flange portion. (3a) Deviated to the side. The second flange portion (3b) is formed of a hard synthetic resin material and cannot be switched to the open posture. In this case, the door portion (10) formed on the outer peripheral edge of the first flange portion (3a) is slightly displaced to the second flange portion (3b) side to the second flange portion (3b). Since it can contact | abut, the volume in the winding part (4) can ensure large and is preferable.

  In each of the above-described embodiments, the body portion is configured by the first body portion and the second body portion that are divided by the plane in the direction perpendicular to the axis at the intermediate portion in the length direction. However, in the present invention, this body portion may be provided in one of the spool portions, or may be formed separately from both spool portions, and the first spool portion and the second spool portion may be connected via this body portion. You may connect.

  Further, as in the third embodiment shown in FIGS. 7 and 8, the body (2) is divided into a first body (2a) formed on the first spool (1a) and a second spool ( 1b), the second body portion (2b) is formed, and the first body portion (2a) is externally or internally fitted to the second body portion (2b). The one spool portion (1a) and the second spool portion (1b) may be connected to each other.

  That is, as shown in FIG. 7, the first body portion (2a) has engagement grooves (12) formed at two locations in the circumferential direction, and is engaged with the base end portion of the engagement groove (12). A recess (13) is formed. On the other hand, the second body portion (2b) is provided with a locking projection (14) on the inner surface of the tip. The second body portion (2b) is fitted on the first body portion (2a), and the engaging protrusion (14) is guided by the engaging groove (12), and then the second body portion ( When the engaging protrusion (14) is fitted into the engaging recess (13) by rotating 2b) in the circumferential direction, both spool portions (1a, 1b) are thereby connected to each other. In a state where both spool portions (1a, 1b) are connected to each other, as shown in FIG. 8, the first body portion (2a) and the second body portion (2b) are formed in a double cylinder shape. Therefore, the strength of the entire fishing line spool (1) can be increased.

  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 flange portion is formed to have a uniform thickness, and the door portion is formed on the outer peripheral edge portion thereof. However, if an annular groove portion is formed along the inner peripheral edge of the door portion, the door portion can be easily switched between an opening posture and a closing posture by bending the groove portion like a hinge, which is preferable. .

  In the above-described embodiment, the case where the long body is a fishing line has been described. However, the 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 long body spool of the present invention is suitable for a fishing line spool because the flange portion can be easily increased in size and the end of the long body can be reliably held by the door portion. It is also suitable for spools used for other long bodies such as packaging tapes.
