Description

  The present invention is a spool around which a belt-like body such as a fishing tape, a handicraft thread, or a metal wire, or a strip-like body such as a wrapping tape is wound, and a pair of cylindrical bodies divided by a plane perpendicular to an axis. More specifically, the spool portion is connected to both spool portions without backlash, and the outer peripheral surface of the barrel portion can be formed into a smooth continuous cylindrical surface, which is wound around the barrel portion. The present invention relates to a spool for a long body that can prevent the long body from being caught between both spool portions and can smoothly feed out the long body from a winding portion.

  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 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.

  Therefore, conventionally, in order to solve the above problems, a cylindrical body portion is divided by an axial orthogonal plane, and a first spool portion including one body portion and a first flange portion extending from one end thereof, A separate type in which the other spool portion and the second spool portion including the second flange portion extending from the other end are formed separately from each other, and both the spool portions are connected to each other at the aforementioned barrel portion. (See, for example, Patent Document 2, paragraph 0029).

JP 2002-153189 A JP 2002-369646 A

  The conventional separate type spool has an advantage that the flange portion can be easily enlarged when injection molding is performed with a synthetic resin. However, in this prior art, since the above-described body portions are connected to each other, the connection portion is likely to be displaced, and the outer peripheral surface of the body portion is rattled so that the long body cannot be wound in an aligned state. is there. In particular, when both spool portions are connected to each other by providing an engaging portion on one spool portion and an engaging portion on the other spool portion and engaging the engaging portion with the engaging portion, There is a problem that a gap is easily generated between the spool portions, and a long body such as a fishing line enters into the gap as far as the bite, and the long body cannot be smoothly fed out. In addition, the above-described gap is likely to further widen when the long body enters, and there is a problem that a larger amount of the long body is bitten.

  The technical problem of the present invention is to solve the above-mentioned problems and to connect the pair of spool parts without backlash to make the outer peripheral surface of the barrel part smooth even though the flange part is a separate type spool that can be easily enlarged. It can be formed on a continuous cylindrical surface, prevents the long body wound around this body portion from being caught between both spool parts, and allows the long body to be smoothly fed out from the winding portion. It is to provide a spool for a scale.

In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 7 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 part (4) around which the long body (5) is wound is formed around the body part (2) between the flange parts (3), and the body part (2) is formed. The first body part (2a) and the second body part (2b) are divided into a first body part (2a) and a first flange part (3a) extending from one end of the first body part (2a). The first spool portion (1a) including the second spool portion (1b) including the second body portion (2b) and the second flange portion (3b) extending from the other end are formed separately from each other. A spool for a long body in which both spool portions (1a, 1b) are connected to each other by the body portion (2a, 2b), and is connected to the connecting end surface of the first body portion (2a). An annular convex part (8) is formed on the periphery, and the second body part ( 2b), an annular recess (9) is formed at a portion facing the annular protrusion (8), and the first body portion (2a) and the second body portion (2b) are connected to each other. It is characterized in that the above-mentioned annular convex part (8) is configured to fit into the above-mentioned annular concave part (9) when connecting.

  When the first spool portion and the second spool portion are connected, the annular convex portion is fitted into the annular concave portion, so that the first trunk portion and the second trunk portion are connected without backlash. The outer peripheral surface of the body is formed into a smoothly continuous cylindrical surface. It is difficult to form a gap between the two body portions, and it is possible to prevent the long body from being bitten between them. Also, even if a slight gap is formed between the two body parts, the long body does not enter more than the radial depth of the annular recess, and the gap is formed by the entrance of the long body. There is no such thing as spreading.

  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 a decoration, packaging, etc. 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.

  The first body portion and the second body portion may be connected inseparably with an adhesive or the like, but may be connected in a separable manner with a connection member such as a screw structure. For example, the above-mentioned two body parts are provided by providing an engaging part in the above-mentioned one body part and providing an engaging part in the other body part and engaging this engaging part with the above engaging part. Can be connected to each other. In this case, since the annular convex portion is fitted in the annular concave portion, it is difficult to create a gap between the spool portions, and the body portions can be easily connected to each other without requiring treatment such as adhesion. It is preferable.

  In addition, when said engagement is performed by rotating one trunk | drum part to the surroundings of an axial center with respect to the other trunk | drum part, said cyclic | annular convex part is fitting in said cyclic | annular recessed part. Therefore, it is preferable because the trunk portion can be guided and smoothly rotated and can be easily engaged.

  Said flange part is not limited to a specific shape, The 1st flange part and the 2nd flange part may be disk shape mutually parallel. However, an annular door portion is formed on the outer peripheral edge of at least one flange portion, the front end side of this door portion is displaced to the other flange portion side, and the front end portion of this door portion is moved to the other flange portion. In this case, it is preferable that the end portion of the elongated body can be reliably held by the door portion.

  The door portion is not limited to a specific shape, but the door portion is switched between a closed posture in which the distal end side of the door portion is displaced toward the other flange portion side and an open posture separated from the other flange portion. If it is configured, 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 guided to the winding part by switching to the open position. It is preferable because it can be wound.

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

  Since the first body part and the second body part are connected without backlash, and the outer peripheral surface of the body part is formed into a smoothly continuous cylindrical surface, it is possible to wind the long body in an aligned state. it can. Further, it is difficult to form a gap between the two body portions, and it is possible to prevent the long body from being bitten between them. Even if a slight gap is formed between the two body portions, the long body does not enter the depth of the annular recess more than the radial depth, and the above-mentioned gap is widened by entering the long body. Since there is no such thing, the amount of the long body entering can be reduced. As a result, the long body wound around the winding part can be smoothly fed out from the winding part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an 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 first spool portion and a second spool portion before assembly. FIG. 3A is an enlarged perspective view of the vicinity of the body portion, FIG. 3A is a 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). A winding part (4) is formed around the trunk part (2) between the flange parts (3), and a long fishing line (5) is wound around the winding part (4). Turned.

  As shown in FIGS. 1 and 2, the fishing line spool (1) includes a first body portion (2a) and a second body portion (2a) formed by a plane in which the body portion (2) is orthogonal to the substantially central portion in the axial direction. It is divided into a body portion (2b) and is composed of a first spool portion (1a) and a second spool portion (1b) formed separately from each other. The first spool portion (1a) includes the first body portion (2a) and a first flange portion (3a) extending from one end thereof, and the second spool portion (1b) includes the first spool portion (1b). 2 including a body portion (2b) and a second flange portion (3b) extending from one end thereof.

  The first body part (2a) is provided with a groove-like engaging part (6), and the second body part (2b) is provided with a hook-like locking part (7). After inserting the locking portion (7) into the engaging portion (6), the second spool portion (1b) is rotated around the axis of the trunk portion (2) by a predetermined angle, for example, about 35 degrees. The engaging portion (7) is securely engaged with the engaging portion (6). By this engagement, the first body part (2a) and the second body part (2b) are detachably connected to each other, and the first spool part (1a) and the second spool part (1b) Is united.

  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 a so-called inlay manner.

  Due to this fitting, when the second spool portion (1b) is rotated for the above engagement, the second spool portion (1b) is smoothly guided around the axis. Also, by the above fitting, the outer peripheral surface of the body part (2) is formed into a smoothly continuous cylindrical surface. When the fishing line (5) is wound around the winding part (4), both body parts (2a 2b) The fishing line (5) can be prevented from entering between. If there is a slight gap between the body parts (2a, 2b) due to dimensional errors during production, the fishing line (5) may enter the gap. Even if the fishing line (5) enters into the gap, it does not enter more than the radial depth of the annular recess (9).

  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. However, the flexible material is not limited to a specific material, and as will be described later, the door portion (10) can be brought into contact with the other flange portion (3) with a predetermined pressing force, and is wound long. What is necessary is just to have the hardness which can receive a scale body reliably. The flexibility of the flexible material is, for example, a measurement method stipulated in JIS K7215, preferably a type D durometer hardness (HDD) of 30 to 70, more preferably an HDD of 40 to 60. 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. At this time, since the outer peripheral surface of the body portion (2) is formed into a smoothly continuous cylindrical surface, the fishing line (5) is easily wound in an aligned state.

  By the winding described above, both the 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). The part (10) is extended outward by a predetermined length (L) from the contact position with the other door part (10). Therefore, even if the flange interval is widened by the pressing force when the fishing line (5) is wound, if the door portions (10) are switched to the closed position (X), the door portion (10) is elastic. The deformed state is maintained in contact with the other door (10) with a predetermined pressing force. 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 above embodiment, both spool portions are formed of a flexible synthetic resin material. However, according to the present invention, both spool portions can be made of any material, and can be made of different materials. For example, in Modification 2 shown in FIG. 5, the first spool portion (1a) is formed of a flexible synthetic resin material such as polypropylene resin as in the above embodiment, and the first flange portion (3a) An annular door portion (10) is formed on the outer peripheral edge portion, and the front end side of the door portion (10) is displaced toward the second flange portion (3b) side of the second spool portion (1b). On the other hand, 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 second flange portion (3b) is formed in a flat disk shape, and no door portion is formed on the outer peripheral edge portion thereof.

  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 the second modification, the shape of the door portion is not limited to the above shape, and can be formed in an arbitrary shape. For example, in Modification 3 shown in FIG. 6, the first flange portion (3a) is formed to have a larger diameter than the second flange portion (3b), and a door portion is formed on the outer peripheral edge of the first flange portion (3a). (10) is formed. And the front end of this door part (10) is extended outward from the contact position with the second flange part (3b), and the door part (10) is displaced inward from the front end (11) of the door part (10). The second flange portion (3b) is in contact with 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). Thus, the possibility of creating a gap between the doors (10, 10) can be further eliminated, and the fishing line can be securely clamped and held at an arbitrary position.

  In Modification 4 shown in FIG. 7, an annular door portion (10) is formed on the outer peripheral edge portion of the second flange portion (3b), and the front end side of the door portion (10) is connected to the first flange portion (3a) side. Is deviated. 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.

  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 the above embodiment, the locking portion is engaged with the engaging portion by rotating the second spool member by a predetermined angle with respect to the first spool member. However, in the present invention, the engaging portion may be engaged with the engaging portion without being rotated. Furthermore, the first body member and the second body member may be fixed with a screw member, or may be fixed inseparable with an adhesive or the like.

  Moreover, in each said embodiment, the flange part was formed in uniform thickness and the door part was formed in the outer periphery part. 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 like a hinge in the groove portion, preferable.

  Further, in the present invention, the door portion may be omitted. In this case, for example, a locking groove for locking the end portion of the long body is provided in the flange portion, or a separate cover is provided. A member may be provided. When these door portions are omitted, both spool portions can be formed of a hard material.

  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 spool for a long body of the present invention is a so-called separate type spool whose flange portion can be easily enlarged, but a cylindrical surface in which both spool portions are connected without backlash and the outer peripheral surface of the trunk portion is smoothly continuous. The long body wound around the body portion can be prevented from being caught between both spool portions, and the long body can be smoothly fed out from the winding portion. Although suitable, it is also suitable for spools used for other long bodies such as handicraft yarn and packaging tape.
