Description

[Technical Field]

[0001] The present disclosure relates to a reel for accommodating a long object such as a hose or a cord. [Background technology]

[0002] For example, in factories and the like that handle various machine tools, air blow guns that spray compressed air supplied from compressors, high-pressure tanks, and the like are used. Since workers hold these air blow guns by hand when working with them, they are connected to flexible hoses. Conventionally, air blow guns have generally been used by connecting them to spiral hoses in a suspended form (see, for example, Patent Document 1). Spiral hoses are easy to use because they do not require any special installation work. Furthermore, because the spiral hose itself is flexible, it can be configured to return to its original position when the user lets go of it, and is therefore widely used due to its high convenience and simple configuration. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-225586 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with repeated use and when an air blow gun is suspended over a long period of time, the elasticity of the spiral hose itself weakens, leading to plastic deformation and causing the spiral hose to stretch. Furthermore, when the air blow gun connected to the spiral hose is released, the air blow gun may be pulled up with force and collide with surrounding objects or people. Thus, spiral hoses have issues that need improvement in terms of durability and safety.

[0005] Meanwhile, reels have been known in the past that are configured to automatically reel in hoses, cords, etc. Using such reels is highly convenient and offers greater durability and safety than using spiral hoses.

[0006] However, the reel needs to be used in a properly fixed state, as there is a risk that the reel itself may move when the worker pulls out the hose, etc. Although conventional reels can be fixed to the wall surface 300, etc. using screws, there has been a demand for a reel that can be attached and detached more easily.

[0007] An object of the present disclosure is to provide a reel that is durable and safe, can be easily fixed, and can also be easily removed. [Means for solving the problem]

[0008] The present disclosure solves the above-mentioned problems by the following solutions. Note that, for ease of understanding, the following description will be given with reference numerals corresponding to the embodiments of the present disclosure, but the present disclosure is not limited to these.

[0009] The first disclosure is a reel (1) for storing and winding a flexible elongated object (200), the reel (1) comprising: a rotatably arranged drum (30) around which the elongated object (200) is wound; a housing (10, 20) arranged to cover the drum (30); a magnet (90) fixed to at least one of the front and rear surfaces of the housing (10, 20) that intersects with the center of rotation (O) of the drum (30); and a plurality of support parts (100) provided to protrude beyond the magnet (90) and the housing (10, 20) in a direction along the center of rotation (O) of the drum (30).

[0010] The second disclosure is a reel (1) characterized in that, in the reel (1) described in the first disclosure, when viewed from one direction along the rotation center (O) of the drum (30), the magnets (90) are arranged spaced apart on a magnet arrangement line (L1), which is an imaginary straight line, and the support parts (100) are arranged spaced apart on support part arrangement lines (L2, L3), which are imaginary straight lines along the magnet arrangement line (L1), and there are multiple support part arrangement lines (L2, L3) on either side of the magnet arrangement line (L1).

[0011] The third disclosure is the reel (1) described in the second disclosure, characterized in that the housing (10, 20) has an opening (23) through which the long object (200) wound on the drum (30) passes when being unwound, and when viewed from one direction along the rotation center (O) of the drum (30), if the direction in which an imaginary straight line (L1) extending from the rotation center (O) of the drum (30) to the opening center of the opening (23) extends is defined as the reference unwound direction of the long object (200), the magnet arrangement line (L1) and the support part arrangement lines (L2, L3) are along the reference unwound direction.

[0012] The fourth disclosure is the reel (1) described in the third disclosure, characterized in that when viewed from one direction along the rotation center (O) of the drum (30), the magnet arrangement line (L1) overlaps with an imaginary straight line (L1) extending from the rotation center (O) of the drum (30) to the opening center of the opening (23).

[0013] The fifth disclosure is a reel (1) characterized in that, in the reel (1) described in the fourth disclosure, when viewed from one direction along the rotation center (O) of the drum (30), two magnets (90) are arranged on either side of the rotation center (O) of the drum (30), and two support parts (100) are arranged spaced apart on one support part arrangement line (L2, L3) and are arranged in line symmetry with the magnet arrangement line (L1) as an axis of symmetry.

[0014] The sixth disclosure is the reel (1) according to any one of the first to fifth disclosures, characterized in that the support part (100) is made of an elastic body. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to provide a reel that is durable and safe, can be easily fixed, and can also be easily removed. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0018] (Embodiment) FIG. 1 is a front view of a reel according to the present disclosure. FIG. 2 is a rear view of a reel according to the present disclosure. FIG. 3 is a bottom view of a reel according to the present disclosure. FIG. 4 is a cross-sectional view of a reel according to the present disclosure taken along the line AA in FIGS. 1 and 2. FIG. 5 is a cross-sectional view of a reel according to the present disclosure taken along the line BB in FIGS. 3 and 4. For ease of explanation, the figures include Cartesian coordinates UD (up-down), LR (left-right), and FB (front-rear). In the following description, the orientation of each part will be described using the corresponding coordinates for up-down, left-right, and front-rear directions, along with terms such as front and rear. The Cartesian coordinates UD (up-down), LR (left-right), and FB (front-rear) are used for convenience and are not intended to limit the use of the reel to these orientations.

[0019] In the reel 1 of this embodiment, the long object 200 will be described as a hose for delivering gas, water, or the like, as an example. Note that the reel having the magnet structure of the present disclosure is not limited to a hose, but may also be a reel for winding and storing other long objects such as an electric cord or wire. Note that the long object 200 is omitted from the illustrations as appropriate.

[0020] The reel 1 of this embodiment has a structure that assumes it will be fixed to an attachment object such as a wall surface 300. Here, the attachment object may be not only the wall surface of a building, but also the exterior surface (wall surface) of a machine tool, the side surface (wall surface) of a shelf, locker, etc., and hereinafter these will be simply referred to as a "wall surface" or "wall surface, etc."

[0021] The reel 1 of this embodiment is a reel that winds and accommodates a flexible elongated object 200. The reel 1 includes a first housing 10, a second housing 20, a drum 30, a drum plate 40, a spring presser 50, a spring 60, a joint 70, a shaft 80, a magnet 90, and a support portion 100.

[0022] The first housing 10 is disposed on the rear (back) side of the reel 1 and is formed by resin molding into a generally flat plate shape when viewed macroscopically. The first housing 10 includes a base portion 11, a hook hole 12, a screw hole 13, a magnet mounting portion 14, a support mounting portion 15, a rib 16, a hook 17, an engagement portion 18, and a spring support portion 19. The first housing 10, as well as the second housing 20, drum 30, drum plate 40, spring retainer 50, joint 70, and shaft 80 described below, are all resin molded parts. Note that these parts are not limited to resin molded parts and may be made of metal.

[0023] The base portion 11 is a flat plate-like portion formed approximately parallel in the vertical and horizontal directions, and when viewed from the front and rear sides, it has an approximately square shape with each side and corner bulging out in a rounded shape.

[0024] The hook holes 12 are through-holes that open above the base 11 at equal left and right positions across the magnet arrangement line L1 (described below), and have a generally round flask-like shape with a long, thin opening connected to the top of the circular opening. The hook holes 12 are used to secure the reel 1 to a wall surface 300 (see FIGS. 3 and 4) or the like using screws, hooks, or the like that are pre-attached to the wall surface 300 or the like. The method of securing the reel 1 using the hook holes 12 is one of multiple selectable methods of securing the reel 1 of this embodiment.

[0025] The screw holes 13 are through-holes that open above the base portion 11 at equal left and right positions across the magnet arrangement line L1 (described later). In this embodiment, they are located further outboard than the hook holes 12. The screw holes 13 and the hook holes 12 do not necessarily have to overlap in the vertical direction. The screw holes 13 communicate with through-holes 21a of screw receivers 21 of the second housing 20 (described later). The reel 1 can be attached using a screw hole or nut provided on the wall surface 300 or the like that screws into, by passing a mounting screw (not shown) through the screw receiver 21 of the second housing 20 (described later). Alternatively, the mounting screw may be a tapped screw and directly attached to the wall surface 300 or the like. Furthermore, the reel 1 can be attached to an L-shaped mounting bracket (not shown) using the screw holes 13, and then fixed to a ceiling surface or the like via the mounting bracket. The method of fixing the reel 1 using the screw holes 13 is one of several methods of fixing the reel 1 that can be selected according to this embodiment.

[0026] The magnet mounting portion 14 is a portion where a magnet 90, which will be described later, is mounted, and has a screw hole 14a into which a magnet mounting screw 91 is screwed. The arrangement of the magnet mounting portion 14, i.e., the arrangement of the magnet 90, will be described later.

[0027] The support part attachment part 15 is a portion to which the support part 100, which will be described later, is attached. The support part attachment part 15 has a circular shape when viewed from the rear that is slightly larger than the outer diameter of the support part 100, which will be described later, and is configured as a flat surface that is recessed forward from the rear surface of the first housing 10. The arrangement of the support part attachment part 15, i.e., the arrangement of the magnet 90, will be described later.

[0028] The ribs 16 are ribs that reinforce the first housing 10, and are arranged in a circular ring shape and radially, protruding rearward from the rear surface of the base portion 11.

[0029] The hooks 17 are disposed below the base 11 at equal left and right positions across the rotation center O of the drum 30, and are positioned so as to be visible through an opening 23 in the second housing 20, which will be described later, when viewed from below. The hooks 17 are generally cylindrical protrusions that protrude forward from the base 11. When the user releases the restraining force by releasing the user's hand, the long object 200 being pulled out through the opening 23 is wound around the drum 30 by the action of a spring 60, which will be described later, and pulled into the first housing 10 and the second housing 20. However, as shown in FIG. 5 , by hooking the long object 200 on the left hook 17, the long object 200 can be maintained in a state where it has been pulled out by a desired length. The long object 200 can also be hooked on the right hook 17 in the same manner as described above.

[0030] The engagement portions 18 are provided at a plurality of locations around the periphery of the base portion 11, and have an engagement shape (hole shape) for engaging with engagement protrusions 25 of the second housing 20, which will be described later.

[0031] The spring support portion 19 has a generally cylindrical shape and protrudes forward from the center of the base portion 11. A groove 19a is provided in the cylindrical wall surface of the spring support portion 19, and the center-side end of a spring 60 (described later) engages with this groove 19a. In addition, a drum 30 (described later) is rotatably fitted into the base (rear end) of the outer periphery of the cylindrical wall surface of the spring support portion 19.

[0032] The second housing 20 includes a screw receiver 21, a shaft support portion 22, an opening 23, and a slit 24. The first housing 10 and the second housing 20 form a housing that is disposed to cover the drum 30, which will be described later. In this embodiment, the housing that covers the drum 30 is formed from two parts, the first housing 10 and the second housing 20, but the housing may be formed from three or more parts, or may be a single part.

[0033] The screw receivers 21 are provided at positions corresponding to the screw holes 13, i.e., above the second housing 20, at equal left and right positions across the magnet arrangement line L1 (described below). The screw receivers 21 are configured in a generally cylindrical shape that protrudes toward the rear side of the second housing 20 and has a through hole 21a, a cylindrical wall portion 21b, and a front screw head relief portion 21c. The screw receiver 21 protrudes and extends from the rear side of the second housing 20 to a position where the cylindrical wall portion 21b and the through hole 21a penetrating the interior of the cylindrical wall portion 21b come into contact with the front surface of the base portion 11 of the first housing 10. The screw receiver 21 is also provided with a front screw head relief portion 21c on the front side of the second housing 20, the front end of which is recessed from the front surface of the second housing 20. When a screw (not shown) is inserted into the screw hole 13 to fix the reel 1, the screw head is accommodated within the front screw head recess 21c and is not exposed from the front surface of the second housing 20.

[0034] The shaft support portion 22 is a through-hole that supports the front end side of the shaft 80, which will be described later. The shaft support portion 22 of this embodiment is a through-hole that has a regular hexagonal shape when viewed from the front side, and the hexagonal shape of the fitting protrusion 81 on the front end side of the shaft 80 fits into it.

[0035] The opening 23 is an opening through which the long object 200 wound around the drum 30 (described later) passes when being pulled out. In this embodiment, the opening 23 is provided on the underside of the second housing 20. The opening 23 is configured so that the width in the front-to-rear direction is wider at the left end side of the opening 23 than at the right side of the opening. The reason why the width in the front-to-rear direction at the left end side of the opening 23 is wider than at the right side is to make it easier to hook the long object 200 onto the left hook 17 described above. In addition, by forming the front-to-rear width of the right side of the opening 23 to be narrow, the position of the pulled-out long object 200 can be guided.

[0036] A plurality of slits 24 are provided on the outer peripheral wall surface of the second housing 20 at positions corresponding to the engaging portions 18. On the inner peripheral surface of the second housing 20, engaging protrusions 25 (see FIG. 4 ) are provided adjacent to the slits 24 and protrude toward the inside of the second housing 20. The slits 24 are shaped to allow a mold for forming the engaging protrusions 25 to be inserted. The engaging protrusions 25 engage with the engaging portions 18, thereby attaching the second housing 20 to the first housing 10. Furthermore, by spreading the second housing 20 outward near the slits 24, the engagement between the two can be easily released, allowing the second housing 20 to be easily removed. Inappropriate use, for example, can cause the elongated object 200 to become tangled inside the second housing 20. Even in such cases, the second housing 20 is detachable from the first housing 10, making it easy to attach and remove, thereby providing good maintainability.

[0037] The drum 30 is rotatably disposed, and the elongated object 200 is wound around it. More specifically, the drum rear end 34 of the drum 30 is rotatably fitted to the base (rear end) of the outer periphery of the cylindrical wall surface of the spring support portion 19. The direction of the rotation center O of the drum 30 is the same as the front-to-rear axis in each drawing. The drum 30 has a cylindrical portion 31 having a cavity that opens to the front side, and a flange portion 32 that extends circumferentially in a substantially disk-like shape at the rear end of the cylindrical portion 31. The elongated object 200 is wound around the outer periphery of the cylindrical portion 31. An insertion hole 33 is opened in the cylindrical portion 31, and one end of the elongated object 200 to be wound around the cylindrical portion 31 is inserted into the cylindrical portion 31 through this insertion hole 33, and one end of the elongated object 200 is connected to a connecting portion 72 of a joint 70 (described later).

[0038] The drum plate 40 is attached to the front end side of the drum 30 and is rotatable together with the drum 30. The drum plate 40 has an opening 41 in the center that corresponds to the internal cavity of the cylindrical portion 31 of the drum 30, and a flange portion 42 extends around this opening in a brim-like shape. The elongated object 200 is accommodated between the flange portion 32 of the drum 30 and the flange portion 42 of the drum plate 40.

[0039] The spring retainer 50 is a generally plate-shaped member that is located at the front end of the spring support portion 19. After the spring 60 is attached, both ends of the spring retainer 50 are fixed to the cylindrical portion 31, and the spring retainer 50 rotates together with the drum 30. In addition, an engagement hole 51 is provided in the center of the spring retainer 50, with which an engagement protrusion 71 of a joint 70 (described below) engages, so that the joint 70 can rotate together with the rotation of the spring retainer 50.

[0040] Spring 60 is an elastic, band-like metal plate wound into a spiral shape, and is disposed between drum rear end 34 and spring presser foot 50. The central end of spring 60 engages with groove 19a of spring support portion 19. The outer end of spring 60 engages with an engagement portion (not shown) provided on cylindrical portion 31 of drum 30. With this configuration, when elongated object 200 is pulled out from drum 30, the spring 60's elastic force increases the urging force that urges drum 30 in the direction in which elongated object 200 is unwound, i.e., the spring 60 is charged with elastic force, and elongated object 200 will automatically be wound around drum 30 unless its movement is restricted.

[0041] The joint 70 is configured in a generally cylindrical shape with an open front end and a closed rear end, and the interior is empty when the shaft 80 is not inserted. An engagement protrusion 71 protrudes rearward from the rear end of the joint 70. The engagement protrusion 71 engages with the engagement hole 51 of the spring presser 50, and the joint 70 can rotate integrally with the spring presser 50 and the drum 30. In addition, a connection portion 72 that protrudes outward from the cylindrical surface of the joint 70 is provided. The connection portion 72 is formed in a generally cylindrical shape, and the internal cavity of the connection portion 72 communicates with the internal cavity of the cylindrical shape of the joint 70. The end of the elongated object 200 that is inserted into the cylindrical portion 31 through the insertion hole 33 is connected to the connection portion 72.

[0042] The shaft 80 has a generally cylindrical shape with an open front end and a closed rear end, and has an internal gap. The front end of the shaft 80 is provided with a hexagonal mating protrusion 81 that fits into the hexagonal shape of the shaft support portion 22. Because the shaft support portion 22 and the mating protrusion 81 are mated, rotation of the shaft 80 is restricted and the shaft 80 does not rotate relative to the second housing 20. Furthermore, a female thread portion 82 is provided on the inner surface of the front end of the internal gap of the shaft 80. By connecting a piping connector or the like using this female thread portion 82, a compressed air supply hose or the like from the outside can be connected. The outer diameter of the shaft 80 is smaller approximately near the center in the front-to-rear direction than in the front and rear portions, and a through-hole 83 is provided through this narrower outer diameter portion in a direction perpendicular to the extension direction (front-to-rear direction) of the shaft 80.

[0043] Furthermore, O-rings 84 are disposed in the thicker outer diameter portions of shaft 80 provided before and after the thinner outer diameter portion, ensuring airtightness. With this configuration, compressed air supplied from an external compressed air supply hose or the like connected to female thread portion 82 passes through through-hole 83 to reach connecting portion 72 and is supplied into elongated object 200 connected to connecting portion 72. Furthermore, because shaft 80 is fixed, the external compressed air supply hose or the like connected to female thread portion 82 will not be twisted. Furthermore, although joint 70 rotates with drum 30, the air supply path remains capable of supplying air even when joint 70 rotates.

[0044] The magnet 90 is fixed to the rear surface of the second housing 20, which intersects with the rotation center O of the drum 30, by a magnet mounting screw 91. In this embodiment, a neodymium magnet with a diameter of 20 mm and a thickness of 4 mm is used as the magnet 90. However, other types of magnets, such as ferrite magnets, may be used as long as they provide a magnetic force sufficient to secure the reel 1 to a metal wall surface 300 or the like. The diameter of the magnet 90 is preferably 16 mm to 25 mm, and the thickness is preferably 4 mm to 6 mm. The rear surface of the magnet 90 is located behind the rearmost protruding position on the rear surface of the second housing 20. Therefore, without the support part 100, the surface (rear surface) of the magnet 90 comes into contact with the flat mounting surface (such as the wall surface 300) when the magnet 90 is mounted on the flat mounting surface.

[0045] A plurality of support portions 100 are provided, protruding rearward beyond the magnet 90 and the second housing 20 in a direction along the rotation center O of the drum 30 (front-rear direction). Therefore, when the drum 30 is attached to a flat mounting surface (such as a wall surface 300), the surface (rear surface) of the magnet 90 does not come into contact with the mounting surface (such as the wall surface 300), but the support portions 100 come into contact with the mounting surface (such as the wall surface 300). In this embodiment, the protrusion amount H (see FIG. 3 ), by which the surface (rear surface) of the support portion 100 protrudes beyond the surface (rear surface) of the magnet 90, is set to 0.5 mm. In this embodiment, by setting the protrusion amount H to 0.5 mm, even if the second housing 20 is bent due to the magnetic force of the magnet 90 or warped due to shrinkage after molding or other external forces, only the support portions 100 come into contact with the mounting surface (such as the wall surface 300), and the magnet 90 does not come into contact with the mounting surface. The amount of protrusion H can be changed as appropriate depending on the magnetic force of the magnet 90, the rigidity of the second housing 20, the relative positional relationship between the magnet 90 and the support part 100, and the like.

[0046] Furthermore, it is desirable that the support part 100 be made of an elastic material. In this embodiment, the support part 100 is a disk-shaped support part 100 made of polyurethane rubber (for example, hardness: Shore A70) with a diameter of 13 mm and a thickness of 4 mm, and is fixed to the second housing 20 with an adhesive. Note that the support part 100 is not limited to the polyurethane rubber, and for example, a rubber with excellent anti-slip properties such as silicone rubber (for example, hardness: approximately Shore A70) may also be used. Furthermore, the diameter of the support part 100 depends on the magnetic force of the magnet 90 and the thickness of the support part 100, but is desirably 10 mm or more and 14 mm or less. Furthermore, the thickness of the support part 100 is desirably 3.5 mm or more and 6.0 mm or less. By making the support parts 100 elastic, when the support parts 100 come into contact with the mounting surface (such as the wall surface 300), the support parts 100 undergo slight elastic deformation, which allows all of the support parts 100 to properly contact the mounting surface (such as the wall surface 300). The surface of the support parts 100 may be roughened to increase the coefficient of friction. This is to enhance the effect of preventing the reel 1 from moving due to the pull-out force of the elongated object 200, which will be described later.

[0047] As described above, the reel 1 of this embodiment is configured so that only the support part 100 contacts the mounting surface (such as the wall surface 300), and the magnets 90 do not, making it possible to achieve appropriate fixation to the mounting surface (such as the wall surface 300) with a small number (two in this embodiment) of magnets 90. More specifically, the reel 1 of this embodiment can maintain a fixed position even when the elongated object 200 is pulled out during use, and can be easily removed when desired.

[0048] A prototype reel (comparative example) was produced that had a similar configuration to the reel 1 of the present embodiment, but did not include the support portion 100. Although the prototype could be attached to the wall surface 300, when the long object 200 was actually used by winding a high-pressure hose around the drum 30, the reel moved along the wall surface 300 due to the force acting on the drum 30, the second housing 20, and the like when the high-pressure hose was pulled out. If multiple magnets were provided instead of the support portion 100, it would be possible to prevent the reel from moving along the wall surface 300. However, this configuration would require multiple magnets, which would increase the manufacturing process, increase component costs, and require a large force to remove the reel from the wall surface 300.

[0049] To facilitate fastening and detachment to a wall surface and to enable the fastened state to be maintained during use with a small number of magnets, the reel 1 of this embodiment has a distinctive arrangement of the magnets 90 and support part 100. The arrangement of the magnets 90 and support part 100 will be described below.

[0050] (Layout feature 1) As shown in FIG. 2, multiple magnets 90 are spaced apart along a virtual magnet arrangement line L1. Multiple support units 100 are spaced apart along support unit arrangement lines L2 and L3, which are virtual lines that extend along the magnet arrangement line L1. These support unit arrangement lines L2 and L3 are located on either side of the magnet arrangement line L1. Here, "along the magnet arrangement line L1" includes being parallel to the magnet arrangement line L1, but does not necessarily mean being strictly parallel; it refers to being along a line that can be considered parallel. Therefore, for example, the support unit arrangement lines L2 and L3 may be parallel to the magnet arrangement line L1, or may be arranged at an angle of approximately 5° or less with respect to the magnet arrangement line L1. The meanings of terms such as "along" and "along" are the same as those of "along the magnet arrangement line L1" described above, including the following descriptions.

[0051] More specifically, in this embodiment, two magnets 90 are spaced apart on the magnet imaginary line L1. Two supports 100 are spaced apart on the support unit arrangement line L2, and two supports 100 are spaced apart on the support unit arrangement line L3. The support unit arrangement lines L2 and L3 are parallel to the magnet imaginary line L1, and the magnet imaginary line L1 is sandwiched between the support unit arrangement lines L2 and L3. This configuration allows the attractive force of the magnetic force to act approximately evenly on the magnet imaginary line L1, allowing the supports 100 arranged on the support unit arrangement lines L2 and L3 to come into approximately even contact with the wall surface 300, etc., thereby enabling stable fixation.

[0052] (Layout feature 2) Furthermore, when viewed from one side (e.g., rearward) along the rotation center O of the drum 30, the direction in which an imaginary straight line L4 (which in this embodiment coincides with the magnet imaginary line L1) extending from the rotation center O of the drum 30 to the opening center of the opening 23 extends is defined as the reference pull-out direction of the elongated object (the direction along the straight line L4). In this embodiment, the opening center of the opening 23 is the center of the width of the opening 23 when viewed from the front. Furthermore, while satisfying the above-mentioned arrangement characteristic 1, the magnet arrangement line L1 and the support portion arrangement lines L2 and L3 are aligned along the reference pull-out direction.

[0053] When the elongated object 200 is pulled out, a force pulling the drum 30 in the pulling direction and a rotational torque acting as the drum 30 rotates act on the first housing 10. These forces may cause the position of the reel 1, which is fixed using the magnet 90, to move when the elongated object 200 is pulled out. However, if the configuration of the above-described arrangement feature 2 is satisfied, the resistance to the force acting when the elongated object 200 is pulled out is increased, and movement of the reel 1 can be effectively suppressed.

[0054] (Layout feature 3) When viewed from one direction along the rotation center O of the drum 30 (for example, from the rear), the magnet arrangement line L1 overlaps with an imaginary line extending from the rotation center O of the drum 30 to the center of the opening 23. This further enhances the effect of suppressing movement of the reel 1 obtained by the above-mentioned arrangement feature 2.

[0055] (Layout feature 4) When viewed from one side (e.g., rearward) in the direction along the rotation center O of the drum 30, two magnets 90 are arranged on either side of the rotation center O of the drum. Two support parts 100 are arranged on each of support part arrangement lines L2 and L3, spaced apart and symmetrical with respect to the magnet arrangement line L1 as the axis of symmetry. This allows the magnets 90 and support parts 100 to be arranged in a balanced manner around the rotation center O of the drum 30 using a minimum number of magnets 90 and support parts 100, thereby achieving stable fixation.

[0056] (Layout feature 5) When viewed from one side along the rotation center O of the drum 30 (for example, from the rear), the magnet 90 is positioned outside the outermost diameter of the drum 30 (see the positional relationship between the screw holes 14a and the drum 30 in FIG. 5). This positions the magnet 90 away from the rotation center O of the drum 30, increasing the torque that counteracts the rotational torque acting on the first housing 10 when the elongated object 200 is pulled out, further enhancing the effect of suppressing movement of the reel 1.

[0057] The configuration of the reel 1, excluding the magnet 90 and the support part 100, i.e., the configuration for automatically winding and storing the long object 200, is basically the same as that of conventionally used reels. Therefore, the reel 1 of this embodiment has good durability and safety. Furthermore, by appropriately positioning the magnet 90 and the support part 100, it can be easily fixed and removed.

[0058] As described above, the reel 1 of this embodiment includes a support portion 100 that protrudes beyond the magnet 90. This allows the reel 1 of this embodiment to be durable and safe, to be easily fixed, and to be easily removed. Furthermore, it is possible to realize a reel in which the position fixed by the magnet is unlikely to move when the elongated object 200 is pulled out. Furthermore, by providing the above-mentioned multiple arrangement features, the effect of the fixed position being unlikely to move can be further enhanced. Furthermore, because the support portion 100 is made of an elastic body, the effect of the fixed position being unlikely to move can be further enhanced.

[0059] (Variations) The present disclosure is not limited to the above-described embodiments, and various modifications and variations are possible, and these are also within the scope of the present disclosure.

[0060] (1) In the embodiment, two magnets 90 and four support parts 100 are provided, and the respective arrangements have been specifically illustrated. This is not limiting, and for example, the number of magnets or the number of support parts may be increased or decreased. In such cases, it is not necessary to have a configuration that satisfies all four of the arrangement features 1 to 4, and they may be selectively adopted as appropriate depending on the usage pattern.

[0061] (2) In the embodiment, the magnet 90 and the support portion 100 are provided only on the rear first housing 10. However, this is not limiting, and the magnet and support portion may be provided on both sides of the drum that intersect the center of rotation, i.e., on both the front and rear sides. This allows the long object to be fixed with the winding direction reversed, and the object can be easily fixed in a direction that is convenient for use depending on the location of use. In this case, it is preferable to provide a structure equivalent to the female thread portion 82, which can supply air from outside, on the rear side as well, so that a cover member can be attached as appropriate.

[0062] (3) In the embodiment, in addition to the fixing method using the magnet 90, a fixing method of the reel 1 using the hook hole 12 and a fixing method of the reel 1 using the screw hole 13 can be used. However, the present invention is not limited to this. For example, a fixing method of the reel 1 using the hook hole 12 and a fixing method of the reel 1 using the screw hole 13 may not be used. In other words, a configuration may be adopted that does not include a structure that penetrates the first housing 10 and the second housing 20 in the front-to-rear direction (the direction along the rotation center O of the drum 30), such as the hook hole 12 or the screw hole 13. As a result, although the fixing method is limited to the method using a magnet, the outer shape of the first housing 10 and the second housing 20 can be reduced in size to a size close to the outer diameter shape of the drum 30.

[0063] (4) In the embodiment, an example has been described in which the support unit 100 is provided as a separate component attached to the first housing 10. However, this is not limiting, and for example, a part or all of the support unit 100 may be configured as one piece with the first housing 10. In this case, the support unit 100 and the first housing 10 may be integrally molded by being formed from the same resin material. Alternatively, the support unit 100 may be prepared as a separate component and integrated with the first housing 10 by insert molding or two-color molding when molding the first housing 10.

[0064] The embodiments and modifications may be used in combination as appropriate, but detailed description thereof will be omitted. The present disclosure is not limited to the embodiments described above. [Explanation of symbols]
