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. This air blow gun is connected to a flexible hose because an operator holds it by hand when working with it. Conventionally, air blow guns have generally been used by connecting it to a spiral hose in a suspended form (see, for example, Patent Document 1). A spiral hose can be easily used because it does not require special installation work or the like to use it. In addition, since the spiral hose itself is elastic, it can be configured to return to its original position when the user releases it, and it is widely used because of its high convenience and simple configuration. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2000-225586 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the spiral hose loses elasticity and undergoes plastic deformation due to repeated use and hanging the air blow gun for a long period of time, causing the spiral hose to become stretched. In addition, when the air blow gun connected to the spiral hose is released from the hand, the air blow gun may be pulled up with force and may collide with surrounding objects or people. Thus, the spiral hose has issues that need to be improved in terms of durability and safety.

[0005] Meanwhile, reels have been known that are configured to automatically wind up hoses, cords, etc. The use of such reels is highly convenient, and is more durable and safer than the use of spiral hoses.

[0006] However, the reel needs to be used in a properly fixed state because 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 problems by the following solving means. Note that, for ease of understanding, the following description will be given with reference symbols corresponding to the embodiments of the present disclosure, but the present disclosure is not limited thereto.

[0009] The first disclosure is a reel (1) that winds and stores a flexible elongated object (200), the reel (1) including: a rotatably arranged drum (30) around which the elongated object (200) is wound; a housing (10, 20) that is 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 intersect with a rotation center (O) of the drum (30); and a plurality of support parts (100) that protrude beyond the magnet (90) and the housing (10, 20) in a direction along the rotation center (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 center of rotation (O) of the drum (30), the magnets (90) are arranged at a distance from one another on a magnet arrangement line (L1), which is an imaginary straight line, and the support parts (100) are arranged at a distance from one another on support part arrangement lines (L2, L3), which are imaginary straight lines along the magnet arrangement line (L1), and the support part arrangement lines (L2, L3) are located on multiple sides of the magnet arrangement line (L1).

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

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

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

[0014] A sixth disclosure is a 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. Effect 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 description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, one 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 cut at the position of the arrow AA in FIG. 1 and FIG. 2. FIG. 5 is a cross-sectional view of a reel according to the present disclosure cut at the position of the arrow BB in FIG. 3 and FIG. 4. In addition, for convenience of explanation, orthogonal coordinates UD (up-down), LR (left-right), and FB (front-rear) are provided in the figures, and in the following explanation, the directions of each part are explained using the directions of up-down, left-right, and front-rear corresponding to these coordinates, together with terms such as front side and rear side. Note that the expressions of the orthogonal coordinates UD (up-down), LR (left-right), and FB (front-rear) are set for convenience, and do not limit the use form of the reel to these directions.

[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 structure using the magnet of the present disclosure is not limited to a hose, and may be a reel for winding and storing other long objects such as electric cords, wires, etc. Note that the illustration of the long object 200 is omitted as appropriate.

[0020] The reel 1 of this embodiment has a structure that assumes that 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 or 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 portion mounting portion 15, a rib 16, a hook 17, an engagement portion 18, and a spring support portion 19. Including the first housing 10, the second housing 20, the drum 30, the drum plate 40, the spring presser 50, the joint 70, and the shaft 80, which will be described below, are all resin molded products. Note that these parts are not limited to being resin molded products, 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 being rounded and bulging.

[0024] The hook holes 12 are through holes that open above the base portion 11 at equal positions on the left and right of the magnet arrangement line L1 described below, and open in a generally round flask shape with a long and thin opening connected to the top of the circular opening. The hook holes 12 are used to fix the reel 1 to a wall surface 300 (see Figs. 3 and 4) or the like using screws, hooks, or the like that are attached in advance to the wall surface 300 or the like. The method of fixing the reel 1 using the hook holes 12 is one of the multiple selectively usable methods of fixing the reel 1 of this embodiment.

[0025] The screw holes 13 are through holes that open at equal positions on the left and right sides of the magnet arrangement line L1 described later above the base portion 11, and in this embodiment, are located on the left and right outside of the hook hole 12. The screw holes 13 and the hook hole 12 do not have to overlap in the vertical direction. The screw holes 13 communicate with the through holes 21a of the screw receivers 21 of the second housing 20 described later. The reel 1 can be attached using a screw hole or nut into which the mounting screw provided on the wall surface 300 or the like is screwed through the screw receivers 21 of the second housing 20 described later. 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 or the like not shown using the screw holes 13, and the reel 1 can be fixed to a ceiling surface or the like via the mounting bracket or the like. The method of fixing the reel 1 using the screw holes 13 is one of the methods of fixing the reel 1 of this embodiment that can be selectively used in multiple ways.

[0026] The magnet mounting portion 14 is a portion where a magnet 90, which will be described later, is attached, 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 attachment portion 15 is a portion to which the support portion 100 described later is attached. The support attachment portion 15 has a circular shape slightly larger than the outer diameter of the support portion 100 described later when viewed from the rear, and is configured as a flat surface recessed forward from the rear surface of the first housing 10. The arrangement of the support attachment portion 15, i.e., the arrangement of the magnets 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 positions evenly spaced on both sides of the rotation center O of the drum 30, and are positioned so as to be visible through an opening 23 of the second housing 20, which will be described later, when viewed from below. The hooks 17 are generally cylindrical projections projecting forward from the base 11. When the user releases his / her hand and the restraining force is released, the long object 200 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 kept in a state of being 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 an engagement protrusion 25 of the second housing 20 described later.

[0031] The spring support part 19 protrudes forward in a generally cylindrical shape from the center of the base part 11. A groove 19a is provided in the cylindrical wall surface of the spring support part 19, and a center side end part 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 part 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 described below. Note that in this embodiment, the housing that covers the drum 30 is formed of two parts, the first housing 10 and the second housing 20, but the housing may be formed of three or more parts, or may be one part.

[0033] The screw receiver 21 is provided at a position corresponding to the screw hole 13, that is, above the second housing 20, at a position evenly spaced to the left and right across the magnet arrangement line L1 described below. The screw receiver 21 is configured in a substantially cylindrical shape protruding 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 extends toward the rear side of the second housing 20, protruding to a position where the cylindrical wall portion 21b and the through hole 21a penetrating the inside of the cylindrical wall portion 21b contact the front side of the base portion 11 of the first housing 10. The screw receiver 21 is provided with a front screw head relief portion 21c with an inner diameter slightly larger than the through hole 21a on the front side of the second housing 20, and the front end side of the cylindrical wall portion 21b is a flat surface recessed from the front surface of the second housing 20. When reel 1 is fixed by inserting a screw (not shown) through screw hole 13, the screw head fits within front screw head recess 21c and is not exposed from the front surface of second housing 20.

[0034] The shaft support portion 22 is a through hole that supports the front end side of the shaft 80 described later. The shaft support portion 22 in 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 such that the width in the front-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-rear direction is wider at the left end side of the opening 23 than at the right side is that the shape makes it easier to hook the long object 200 onto the left hook 17 described above. In addition, by forming the front-rear direction width of the right side of the opening 23 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, an engaging protrusion 25 (see FIG. 4) is provided adjacent to the slit 24 and protruding toward the inside of the second housing 20. The slit 24 is shaped so that a die for molding the engaging protrusion 25 can be inserted. The engaging protrusion 25 and the engaging portion 18 are engaged with each other, so that the second housing 20 is attached to the first housing 10. In addition, the engagement between the two can be easily released by spreading the second housing 20 outward near the slit 24, and the second housing 20 can be easily removed. If the method of use is inappropriate, there is a risk that the long object 200 will become entangled in the second housing 20. Even in such a case, the second housing 20 is detachable from the first housing 10 and can be easily attached and removed, so that the maintenance performance is good.

[0037] The drum 30 is rotatably arranged, and the long object 200 is wound around it. More specifically, the drum 30 has a drum rear end 34 rotatably fitted to the base (rear end) side of the outer periphery of the cylindrical wall surface of the spring support part 19. The direction of the rotation center O of the drum 30 is the same as the axis in the front-rear direction in each drawing. The drum 30 has a cylindrical part 31 having a cavity opening to the front side, and a flange part 32 extending in the circumferential direction at the rear end of the cylindrical part 31 in a substantially disk-like shape. The long object 200 is wound around the outer periphery side of the cylindrical part 31. An insertion hole 33 is opened in the cylindrical part 31, and one end side of the long object 200 wound around the cylindrical part 31 is inserted into the cylindrical part 31 through the insertion hole 33, and one end side of the long object 200 is connected to a connection part 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 corresponding 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 long 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 presser 50 is a generally plate-shaped member located at the front end of the spring support part 19. After the spring 60 is attached, both ends of the spring presser 50 are fixed to the cylindrical part 31 and the spring presser 50 rotates together with the drum 30. In addition, an engagement hole 51 is provided in the center of the spring presser 50 with which an engagement protrusion 71 of a joint 70 (described later) engages so that the joint 70 can rotate together with the rotation of the spring presser 50.

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

[0041] The joint 70 is configured in a substantially cylindrical shape with an open front end and a closed rear end, and the inside 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 part 72 protruding outward from the cylindrical surface of the joint 70 is provided. The connection part 72 is formed in a substantially cylindrical shape, and the internal gap of the connection part 72 communicates with the internal gap of the cylindrical shape of the joint 70. The end of the elongated object 200 inserted into the inside of the cylindrical part 31 through the insertion hole 33 is connected to the connection part 72.

[0042] The shaft 80 is configured in a substantially 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 fitting protrusion 81 that protrudes in a hexagonal shape to fit into the hexagonal shape of the shaft support portion 22. Since the shaft support portion 22 and the fitting protrusion 81 are fitted together, the rotation of the shaft 80 is restricted and the shaft 80 does not rotate relative to the second housing 20. In addition, a female thread portion 82 is provided on the inner surface on the front end side of the internal gap of the shaft 80. By connecting a piping connector or the like using this female thread portion 82, a supply hose for compressed air from the outside can be connected. The shaft 80 is configured to have a smaller outer diameter in the vicinity of the approximate center in the front-rear direction than in the front and rear, and a through hole 83 is provided through the portion with a smaller outer diameter in a direction perpendicular to the extension direction (front-rear direction) of the shaft 80.

[0043] In addition, O-rings 84 are arranged at each of the thicker outer diameter portions provided before and after the thinner outer diameter portion of the shaft 80, ensuring airtightness. With these configurations, compressed air supplied from an external compressed air supply hose or the like connected to the female thread portion 82 reaches the connection portion 72 through the through hole 83 and is supplied into the elongated object 200 connected to the connection portion 72. In addition, since the shaft 80 is fixed, the external compressed air supply hose or the like connected to the female thread portion 82 is not twisted. Furthermore, although the joint 70 rotates together with the rotation of the drum 30, the air supply path can continue to be in a state in which air can be supplied even when the joint 70 rotates.

[0044] The magnet 90 is fixed to the rear surface of the second housing 20 intersecting the rotation center O of the drum 30 by a magnet mounting screw 91. In this embodiment, the magnet 90 is a neodymium magnet with a diameter of 20 mm and a thickness of 4 mm, but other types of magnets such as ferrite magnets may be used as long as the magnetism is sufficient to fix the reel 1 to a metal wall surface 300 or the like. The diameter of the magnet 90 is preferably 16 mm or more and 25 mm or less, and the thickness is preferably 4 mm or more and 6 mm or less. The position of the rear surface of the magnet 90 is behind the position of the rearmost protrusion on the rear surface of the second housing 20. Therefore, if the support part 100 is not provided, the surface (rear surface) of the magnet 90 will come into contact with the flat mounting surface (wall surface 300 or the like) when the magnet 90 is mounted on the flat mounting surface.

[0045] The support portion 100 is provided in a plurality of portions so as to protrude rearward from the magnet 90 and the second housing 20 in a direction (front-rear direction) along the rotation center O of the drum 30. Therefore, when the support portion 100 is attached to a flat mounting surface (such as a wall surface 300), the surface (rear surface) of the magnet 90 does not contact the mounting surface (such as a wall surface 300), but the support portion 100 contacts the mounting surface (such as a wall surface 300). In this embodiment, the protrusion amount H (see FIG. 3) of the surface (rear surface) of the support portion 100 protruding from 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 by the magnetic force of the magnet 90 or the second housing 20 is warped by contraction after molding or other external forces, only the support portion 100 can be in contact with the mounting surface (such as a wall surface 300), and the magnet 90 can be in a state of not contacting 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 portion 100, and the like.

[0046] Moreover, it is preferable that the support part 100 is made of an elastic body. 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, which is fixed to the second housing 20 by an adhesive. Note that the support part 100 is not limited to the polyurethane rubber, and may be made of rubber with excellent anti-slip properties such as silicone rubber (for example, hardness: about Shore A70). 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 preferably 10 mm or more and 14 mm or less. The thickness of the support part 100 is preferably 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 an attachment surface (such as the wall surface 300), the support parts 100 undergo slight elastic deformation, and the effect is obtained that all of the multiple support parts 100 can appropriately come into contact with the attachment surface (such as the wall surface 300). In addition, the surface of the support parts 100 may be roughened or the like to increase the coefficient of friction. This is to increase 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, and not the magnet 90, contacts the mounting surface (such as the wall surface 300), and therefore can be appropriately fixed 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 long object 200 is pulled out during use, and can be easily removed when it is desired to remove the reel 1.

[0048] A prototype reel (comparative example) was produced that had the same configuration as the reel 1 of the present embodiment, but did not have the support part 100. Although the prototype could be attached to the wall surface 300, when the high-pressure hose was actually wound around the drum 30 as the long object 200 and used, the reel moved on the wall surface 300 due to the force acting on the drum 30 and the second housing 20 when the high-pressure hose was pulled out. If the support part 100 is not provided and multiple magnets are provided, it is possible to prevent the reel from moving on the wall surface 300 as described above. However, in this configuration, the manufacturing process increases because multiple magnets are arranged, the cost of parts also increases, and a large force is required to remove the reel from the wall surface 300.

[0049] In order to facilitate fastening and detachment to a wall surface and to enable a small number of magnets to maintain the fixed state during use, 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, the magnets 90 are arranged at intervals on the magnet arrangement line L1, which is a virtual straight line. The support parts 100 are arranged at intervals on each of the support part arrangement lines L2 and L3, which are virtual straight lines along the magnet arrangement line L1, and the support part arrangement lines L2 and L3 are arranged 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, and refers to being along a level that can be considered parallel. Therefore, for example, the support part arrangement lines L2 and L3 may be parallel to the magnet arrangement line L1, or may be arranged at an angle of about 5° or less with respect to the magnet arrangement line L1. The meaning of the words "along" and "along" is the same as the meaning of "along the magnet arrangement line L1" in this specification, including the following description.

[0051] More specifically, in this embodiment, two magnets 90 are arranged at a distance on the magnet virtual line L1. Two support parts 100 are arranged at a distance on the support part arrangement line L2, and two support parts 100 are arranged at a distance on the support part arrangement line L3. The support part arrangement line L2 and the support part arrangement line L3 are parallel to the magnet virtual line L1, and the magnet virtual line L1 is sandwiched between the support part arrangement line L2 and the support part arrangement line L3. With this configuration, the attractive force due to the magnetic force acts approximately evenly on the magnet virtual line L1, and each support part 100 arranged on the support part arrangement line L2 and the support part arrangement line L3 can be approximately evenly contacted with the wall surface 300, etc., and stable fixation is possible.

[0052] (Layout feature 2) Furthermore, when viewed from one side along the rotation center O of the drum 30 (e.g., from the rear), 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. And, 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 fixed by the magnet 90 to move when the elongated object 200 is pulled out. However, if the configuration of the above-mentioned arrangement feature 2 is satisfied, the resistance to the force acting when the elongated object 200 is pulled out is increased, and the 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 straight line extending from the rotation center O of the drum 30 to the center of the opening 23. This can further enhance the effect of suppressing the movement of the reel 1 obtained by the above-mentioned arrangement feature 2.

[0055] (Layout feature 4) When viewed from one side in the direction along the rotation center O of the drum 30 (for example, from the rear), two magnets 90 are arranged on either side of the rotation center O of the drum. The support parts 100 are arranged on each of the support part arrangement lines L2, L3, spaced apart from each other and line-symmetrically with respect to the magnet arrangement line L1 as the axis of symmetry. This makes it possible to arrange the magnets 90 and support parts 100 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 disposed outside the outermost diameter of the drum 30 (see the positional relationship between the screw holes 14a and the drum 30 in FIG. 5). As a result, the magnet 90 is disposed at a position away from the rotation center O of the drum 30, and the torque that counteracts the rotation torque acting on the first housing 10 when the long object 200 is pulled out is increased, further enhancing the effect of suppressing the movement of the reel 1.

[0057] The configuration of the reel 1, other than 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 arranging 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 has a support part 100 that protrudes beyond the magnet 90. This allows the reel 1 of this embodiment to have good durability and safety, to be easily fixed, and to be easily removed, and further allows for a reel in which the position fixed by the magnet is unlikely to move when the long 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, since the support part 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 embodiment, 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 are specifically illustrated and described. This is not limiting, and for example, the number of magnets or the number of support parts may be increased or decreased. In that case, it is not necessary to have a configuration that satisfies all four of the arrangement features 1 to 4, and they can be selectively adopted as appropriate depending on the usage form.

[0061] (2) In the embodiment, the magnet 90 and the support part 100 are provided only on the rear first housing 10. However, the present invention is not limited to this, and the magnet and the support part may be provided on both sides intersecting the center of rotation of the drum, 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 easy to use depending on the place of use. In this case, it is preferable to provide a structure equivalent to the female screw part 82 that 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, and 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 that does not include a structure that penetrates the first housing 10 and the second housing 20 in the front-rear direction (the direction along the rotation center O of the drum 30), such as the hook hole 12 and the screw hole 13, may be used. 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, the support part 100 is provided as a separate part attached to the first housing 10. However, the present invention is not limited to this, and for example, a part or the whole of the support part 100 may be integrally formed with the first housing 10. In this case, the support part 100 and the first housing 10 may be integrally molded by forming them from the same resin material. Also, the support part 100 may be prepared as a separate member 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 appropriate combination, but detailed description thereof will be omitted. The present disclosure is not limited to the embodiments described above. [Explanation of symbols]
