Description

TECHNICAL FIELD

[0001] The present application relates to a hose reel that houses a long object such as a hose or an electric wire. BACKGROUND

[0002] For example, in a factory or the like where various machine tools are used, a blow gun that ejects compressed air supplied from a compressor, a high-pressure tank, or the like is used. The blow gun is handled by a worker, and thus is connected to a hose having flexibility. Conventionally, the blow gun is used in a state of being connected to a spiral hose in a suspended manner (see, for example, Patent Literature 1). The spiral hose does not require a special installation operation or the like for use, and thus can be used simply. In addition, the spiral hose itself has stretchability, and thus can be configured to return to an original position when a user releases the spiral hose, and thus is highly convenient and simple in structure, and thus can be used widely.

[0004] PATENT LITERATURE

[0005] Patent Literature 1: Japanese Patent Application Laid-Open No. 2000-225586

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, the spiral hose is weakened in elasticity and plastically deformed due to repeated use and long-time suspension of the blow gun, and the spiral hose becomes in a stretched state. In addition, when the blow gun connected to the spiral hose is released by a hand, the blow gun is pulled back violently, and there is a risk of collision with surrounding objects or people. Thus, the spiral hose has a problem in terms of durability and safety that should be improved.

[0008] On the other hand, conventionally, a hose reel having a structure capable of automatically winding a hose, an electric wire, or the like is known. If such a hose reel is used, convenience is high, durability is high compared to the use of the spiral hose, and safety is also high.

[0009] However, the hose reel has a risk of moving itself when the hose or the like is pulled out by an operator, and thus needs to be used in a state of being fixed properly. The existing hose reel can be fixed to a wall surface 300 or the like using a screw or the like, but a hose reel capable of being installed or detached more simply is desired. SUMMARY

[0010] An object of the present application is to provide a hose reel that is good in durability and safety, can be fixed simply, and is also easy to detach.

[0030] In the pipe winder 1 of the present embodiment, as one example of the long object 200, a case where a hose for conveying gas, water, or the like is cited is explained. In addition, the pipe winder of the present application having a structure using a magnet is not limited to the hose, and can be a pipe winder that winds and houses other long objects such as electric wires, cables, and the like. In addition, regarding the long object 200, the illustration is appropriately omitted.

[0031] The pipe winder 1 of the present embodiment has a structure that is assumed to be used by being fixed to a mounting object such as a wall surface 300 or the like. Here, the mounting object is not only a wall surface of a building, but also a housing surface (wall surface) of a machine tool, a side surface (wall surface) of a shelf, a safe, and the like, and hereinafter, they will be simply referred to as "wall surface" or "wall surface and the like".

[0032] The pipe winder 1 of the present embodiment is a pipe winder that winds and houses a long object 200 having flexibility. The pipe winder 1 has a first housing 10, a second housing 20, a winding drum 30, a winding drum wheel plate 40, a spring pressing plate 50, a spring 60, a joint 70, a shaft 80, a magnet 90, and a support portion 100.

[0033] The first housing 10 is disposed on the rear surface (back) side of the pipe winder 1, and is formed into a substantially flat plate shape macroscopically by resin molding. The first housing 10 has 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. The second housing 20, the winding drum 30, the winding drum wheel plate 40, the spring pressing plate 50, the joint 70, and the shaft 80 described below, including the first housing 10, are all resin molded products. In addition, these components are not limited to resin molded products, and can be composed of metal.

[0034] The base portion 11 is a flat plate-shaped portion formed substantially in parallel in the upper-lower direction and the left-right direction, and the shape observed from the front surface side and the rear surface side is a substantially square shape, and each side and each corner is bulged to have a shape with rounded corners.

[0035] The hooking hole 12 is a through hole opened at positions equally left and right above the base 11, across the magnet arrangement line L1 described later, and has a substantially round flask shape with an elongated extension connected to the upper side of the circular opening. The hooking hole 12 is used to fix the pipe winder 1 to the wall surface 300 or the like with a screw, a hook, or the like installed in advance in the wall surface 300 (see FIG. 1) or the like. The fixing method of the pipe winder 1 using the hooking hole 12 is one of the plurality of fixing methods of the pipe winder 1 of the present embodiment that can be selectively used. Figure 3 and Figure 4 ) or the like. The fixing method of the pipe winder 1 using the hooking hole 12 is one of the plurality of fixing methods of the pipe winder 1 of the present embodiment that can be selectively used.

[0036] The screw hole 13 is a through hole opened at positions equally left and right above the base 11, across the magnet arrangement line L1 described later, and in the present embodiment, is arranged outside left and right of the hooking hole 12. In addition, the screw hole 13 can also not overlap the hooking hole 12 in the vertical direction. The screw hole 13 communicates with the through hole 21a of the screw seat 21 of the second housing 20 described later. The pipe winder 1 can be installed on the screw seat 21 of the second housing 20 described later by a mounting screw, a nut, or the like using a screw hole for a mounting screw provided in the wall surface 300 or the like, by a mounting screw not shown. In addition, the mounting screw can also be a self-tapping screw, and the pipe winder 1 can be directly installed in the wall surface 300 or the like. The pipe winder 1 can also be installed in an L-shaped mounting bracket or the like not shown by the screw hole 13, and the pipe winder 1 can be fixed to the ceiling surface or the like via the mounting bracket or the like. The fixing method of the pipe winder 1 using the screw hole 13 is one of the plurality of fixing methods of the pipe winder 1 of the present embodiment that can be selectively used.

[0037] The magnet mounting portion 14 is a portion where the magnet 90 described later is installed, and has a screw hole 14a for a magnet mounting screw 91. The arrangement of the magnet mounting portion 14, that is, the arrangement of the magnet 90, is described later.

[0038] The support portion mounting portion 15 is a portion where the support portion 100 described later is installed. The support portion mounting portion 15 is a circular shape slightly larger than the outer diameter shape of the support portion 100 described later when viewed from the rear side, and is a flat surface recessed further forward than the rear surface of the first housing 10. The arrangement of the support portion mounting portion 15, that is, the arrangement of the magnet 90, is described later.

[0039] The rib 16 is a rib that reinforces the first housing 10, and is arranged in a circular ring shape and a radial shape protruding further rearward than the rear surface of the base 11.

[0040] The hook 17 is disposed below the base 11 at a position equally left and right from the rotation center O of the reel 30, and is a position that can be observed through the opening 23 of the second case 20 described later when viewed from below. The hook 17 is a substantially cylindrical protrusion protruding forward from the base 11. The long strip 200 pulled out through the opening 23 is wound around the reel 30 and pulled into the first case 10 and the second case 20 by the action of the mainspring 60 described later when the restraining force is released by the user letting go, or the like. However, as shown, by hanging the long strip 200 on the hook 17 on the left, the long strip 200 can be maintained in a state pulled out to a desired length. Also, the long strip 200 can be hung on the hook 17 on the right in the same manner as described above. Figure 5

[0041] The engagement portion 18 is provided in a plurality around the base 11, and has an engagement shape (hole shape) for engaging with the engagement protrusion 25 of the second case 20 described later.

[0042] The mainspring support portion 19 protrudes forward from the center of the base 11 in a substantially cylindrical shape. A groove 19a is provided on the cylindrical wall surface of the mainspring support portion 19, and the center side end portion of the mainspring 60 described later is engaged in the groove 19a. Further, the reel 30 described later is rotatably fitted at the root (rear end) of the outer periphery of the cylindrical wall surface of the mainspring support portion 19.

[0043] The second case 20 has a screw seat 21, an axle support portion 22, an opening 23, and a slit 24. By the first case 10 and the second case 20, a case configured to cover the reel 30 described later is constituted. Also, in the present embodiment, the case covering the reel 30 is constituted by the two members of the first case 10 and the second case 20, but the case can be constituted by three or more members, or can be one member.

[0044] The screw seat 21 is provided at a position corresponding to the screw hole 13, that is, at a position equally left and right from the magnet arrangement line L1 described later above the second case 20. The screw seat 21 is constituted in a substantially cylindrical shape protruding from the rear surface side of the second case 20, and has a through-hole 21a, a cylindrical wall portion 21b, and a front surface screw head avoiding portion 21c. The screw seat 21 protrudes from the rear surface side of the second case 20 and extends to a position where the through-hole 21a penetrating the inside of the cylindrical wall portion 21b contacts the front surface of the base 11 of the first case 10. Further, the screw seat 21 is provided with the front surface screw head avoiding portion 21c having an inner diameter one turn larger than the through-hole 21a on the front surface side of the second case 20, and the front end side of the cylindrical wall portion 21b is a flat surface recessed with respect to the front surface of the second case 20. In the case of fixing the pipe winder 1 by passing a screw not shown through the screw hole 13, the screw head is housed inside the front surface screw head avoiding portion 21c, and the screw head does not protrude from the front surface of the second case 20.​

[0045] The shaft support portion 22 is a through hole that supports the front end side of the shaft 80, which will be described later. In this embodiment, the shaft support portion 22 is a through hole with a regular hexagonal shape when viewed from the front surface side, and it fits into the hexagonal shape of the fitting protrusion 81 on the front end side of the shaft 80.

[0046] The opening 23 is through which the long strip 200, wound on the spool 30 (described later), passes when it is pulled out. In this embodiment, the opening 23 is provided on the lower surface side of the second housing 20. The opening 23 is configured such that its width in the front-rear direction is wider on the left side than on the right side. The wider width on the left side of the opening 23 is because this shape facilitates the operation of hooking the long strip 200 onto the hook 17 on the left side. Furthermore, by forming a narrower front-rear width on the right side of the opening 23, the position of the pulled-out long strip 200 can be guided.

[0047] Multiple gaps 24 are provided on the outer peripheral wall surface of the second housing 20 at positions corresponding to the engaging portions 18. Engaging protrusions 25 (see reference 18) are provided adjacent to the gaps 24 on the inner peripheral surface of the second housing 20. Figure 4 The slit 24 protrudes inward toward the inner side of the second housing 20. The slit 24 is shaped to insert the mold used for forming the aforementioned engaging protrusion 25. The second housing 20 is mounted on the first housing 10 by engaging the engaging protrusion 25 with the engaging portion 18. Furthermore, by extending the second housing 20 outward near the slit 24, the engagement can be easily released, and the second housing 20 can be easily removed. If used improperly, there is a risk that the long object 200 may become entangled inside the second housing 20. Even in such a case, the second housing 20 is freely attachable and detachable from the first housing 10, and installation and removal are easy, thus ensuring good maintainability.

[0048] The spool 30 is configured to rotatably wind the elongated strip 200. More specifically, the rear end 34 of the spool 30 is rotatably fitted into the root (rear end) side of the outer periphery of the cylindrical wall of the spring support portion 19. The direction of the rotation center O of the spool 30 is the same as the axis in the front-rear direction in each figure. The spool 30 has: a cylindrical portion 31 having a cavity opening to the front side; and a flange portion 32 extending in a generally disk-shaped manner in the circumferential direction at the rear end of the cylindrical portion 31. The elongated strip 200 is wound around the outer periphery of the cylindrical portion 31. A through hole 33 is opened on the cylindrical portion 31, through which one end of the elongated strip 200 wound on the cylindrical portion 31 is inserted into the interior of the cylindrical portion 31, and one end of the elongated strip 200 is connected to the connecting portion 72 of the connector 70 described later.

[0049] The drum wheel plate 40 is installed at the front end side of the drum 30 and rotatable together with the drum 30. The drum wheel plate 40 is provided with an opening portion 41 corresponding to the inside hollow of the cylindrical portion 31 of the drum 30 at the center, and a flange portion 42 extending in a flange shape around the opening. The long article 200 is accommodated between the flange portion 32 of the drum 30 and the flange portion 42 of the drum wheel plate 40.

[0050] The spring press plate 50 is a substantially plate-shaped member arranged at the position of the front end of the spring support portion 19. After the spring 60 is installed, both end portions of the spring press plate 50 are fixed to the cylindrical portion 31 and rotatable together with the drum 30. Further, at the center of the spring press plate 50, an engagement hole 51 for engagement of an engagement protrusion 71 of the joint 70 is provided in a manner that the joint 70 is rotatable together with the rotation of the spring press plate 50.

[0051] The spring 60 is a belt-shaped metal plate having elasticity configured in a spiral shape, and is arranged between the drum rear end 34 and the spring press plate 50. The center side end portion of the spring 60 is engaged with the groove 19a of the spring support portion 19. Further, the outside end portion of the spring 60 is engaged with a not-shown engagement portion provided on the cylindrical portion 31 of the drum 30. By this structure, when the long article 200 is pulled out from the drum 30, the elastic force of the spring 60 increases the force applied to the drum 30 in the direction of returning to the long article 200, i.e., becomes a state in which the elastic force is applied, and if the long article 200 is not restricted to move, it is automatically wound on the drum 30.

[0052] The joint 70 is configured in a substantially cylindrical shape with the front end side open and the rear end side closed, and becomes a void without the insertion of the shaft 80 inside. At the rear end of the joint 70, the engagement protrusion 71 protrudes to the rear. The engagement protrusion 71 is engaged with the engagement hole 51 of the spring press plate 50, and the joint 70 is integrated with the spring press plate 50 and the drum 30 and rotatable. Further, on the cylindrical surface of the joint 70, a connection portion 72 protruding to the outside from the cylindrical surface is provided. The connection portion 72 is formed in a substantially cylindrical shape, and the inside void of the connection portion 72 communicates with the void inside the cylindrical shape of the joint 70. The end portion of the long article 200 inserted to the inside of the cylindrical portion 31 through the through hole 33 is connected to the connection portion 72.

[0053] The shaft 80 is formed in a substantially cylindrical shape with an open front end and a closed rear end, and has an empty space inside. A fitting protrusion 81, which is formed in a hexagonal shape, is provided at the front end of the shaft 80 so as to fit with the hexagonal shape of the shaft support portion 22. The shaft support portion 22 is fitted with the fitting protrusion 81, so that the rotation of the shaft 80 is restricted and the shaft 80 does not rotate with respect to the second housing 20. In addition, an internal thread portion 82 is provided on the inner surface of the front end of the empty space inside the shaft 80. By connecting a pipe connector or the like using the internal thread portion 82, a supply hose or the like for compressed air from the outside can be connected. The substantially central portion of the shaft 80 in the front-rear direction is formed to have an outer diameter that is smaller than the outer diameters of the front and rear portions thereof, and a through-hole 83 is provided so as to pass through in a direction orthogonal to the extending direction (front-rear direction) of the shaft 80 at the portion with the small outer diameter.

[0054] In addition, the portions with the thick outer diameters provided on the front and rear of the portion with the small outer diameter of the shaft 80 are each provided with an O-ring 84, so that air tightness is ensured. By these structures, compressed air supplied from the supply hose or the like for compressed air from the outside connected to the internal thread portion 82 passes through the through-hole 83 to reach the connection portion 72, and is supplied into the long object 200 connected to the connection portion 72. In addition, the shaft 80 is fixed, so the supply hose or the like for compressed air from the outside connected to the internal thread portion 82 does not twist. Furthermore, the joint 70 rotates together with the winding drum 30, and even if the joint 70 rotates, the supply passage for air can be in a state in which air can be continuously supplied.

[0055] The magnet 90 is fixed to the rear surface of the second housing 20 intersecting the center O of rotation of the winding drum 30 by a magnet mounting screw 91. In the present embodiment, a neodymium magnet with a diameter of 20 mm and a thickness of 4 mm is used for the magnet 90, and in order to obtain a magnetic force with which the winding device 1 can be fixed to a metal wall surface 300 or the like, another type of magnet such as a ferrite magnet can also be used. In addition, 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 surface of the rear side of the magnet 90 is more toward the rear side than the position of the most rearward protrusion in the rear surface of the second housing 20. Thus, if the mounting surface is a flat surface (wall surface 300 or the like) in a state in which the support portion 100 is not provided, the surface (rear surface) of the magnet 90 is in contact with the mounting surface.

[0056] The support portion 100 is provided protruding more toward the rear than the magnet 90 and the second housing 20 in the direction (front-rear direction) along the center O of rotation of the winding drum 30. Thus, in the case in which the mounting surface is a flat surface (wall surface 300 or the like), the surface (rear surface) of the magnet 90 is not in contact with the mounting surface (wall surface 300 or the like), and the support portion 100 is in contact with the mounting surface (wall surface 300 or the like). In the present embodiment, the amount of protrusion H of the surface (rear surface) of the support portion 100 is larger than the amount of protrusion of the surface (rear surface) of the magnet 90 (refer to FIG. 6).Figure 3 ) is 0.5 mm. In the present embodiment, by setting the protruding amount H to 0.5 mm, even in a case where the second housing 20 is bent due to the magnetic force of the magnet 90, or is warped due to shrinkage after molding, or other external force, it is possible to become a state where only the support portion 100 is in contact with the mounting surface (wall surface 300 or the like), and the magnet 90 is not in contact. In addition, this protruding amount H can be appropriately changed by the magnetic force of the magnet 90, the rigidity of the second housing 20, the relative positional relationship of the magnet 90 and the support portion 100, and the like.

[0057] Further, the support portion 100 is preferably composed of an elastic body. In the present embodiment, for the support portion 100, a disc-shaped support portion 100 of polyurethane rubber (for example, hardness: Shore A 70) having a diameter of 13 mm and a thickness of 4 mm is fixed to the second housing 20 by an adhesive. In addition, as the support portion 100, it is not limited to the above-described polyurethane rubber, and rubber or the like (for example, hardness: around Shore A 70) excellent in slip resistance such as silicone rubber can also be used. Further, the diameter of the support portion 100 also depends on the magnetic force of the magnet 90 and the thickness of the support portion 100, and is preferably, for example, 10 mm or more and 14 mm or less. Further, the thickness of the support portion 100 is preferably 3.5 mm or more and 6.0 mm or less. By making the support portion 100 an elastic body, in a case where the support portion 100 is brought into contact with the mounting surface (wall surface 300 or the like), the support portion 100 slightly elastically deforms, and an effect that all of the plurality of support portions 100 can reliably come into contact with the mounting surface (wall surface 300 or the like) can be obtained. Further, the surface of the support portion 100 can also be roughened or the like to increase the coefficient of friction. This is because an effect that the roll-up device 1 does not move due to the pulling force of the long object 200 described later is improved.

[0058] As described above, the roll-up device 1 of the present embodiment, by the structure where only the support portion 100 is in contact with the mounting surface (wall surface 300 or the like), and the magnet 90 is not in contact, it is possible to reliably fix on the mounting surface (wall surface 300 or the like) by a small number (two in the present embodiment) of magnets 90. More specifically, the roll-up device 1 of the present embodiment can maintain the fixed position even when the long object 200 is pulled out in use, and in a case where it is desired to detach the roll-up device 1, it can be easily detached.

[0059] In a hose reel with the same structure as the hose reel 1 of this embodiment, a prototype (comparative example) of a hose reel without the support portion 100 was manufactured. However, although the prototype could be mounted on the wall 300, when it was actually used to wind a high-pressure hose (200 as a long strip) onto the reel 30, the hose reel moved on the wall 300 due to the force acting on the reel 30, the second housing 20, etc., when the high-pressure hose was pulled out. If multiple magnets were provided instead of the support portion 100, the aforementioned movement of the hose reel on the wall 300 could be prevented. However, in this structure, arranging multiple magnets increases the manufacturing process and component costs, and requires considerable force to remove the hose reel from the wall 300.

[0060] The tube reel 1 of this embodiment features a characteristic arrangement of magnet 90 and support portion 100, which allows for easy fixing and disassembly on the wall surface using a small number of magnets, thereby maintaining a fixed state during use. The arrangement of magnet 90 and support portion 100 will be described below.

[0061] (Configuration Feature 1)

[0062] like Figure 2 As shown, multiple magnets 90 are separately arranged along a magnet arrangement line L1, which serves as a virtual straight line. Furthermore, multiple support portions 100 are separately arranged along each of support portion arrangement lines L2 and L3, which also serve as virtual straight lines, along the magnet arrangement line L1. These support portion arrangement lines L2 and L3 are multiple, separated from the magnet arrangement line L1. Here, "along the magnet arrangement line L1" includes parallelism to the magnet arrangement line L1, but does not need to be strictly parallel; rather, it refers to a degree that can be considered parallel. Therefore, for example, support portion arrangement lines L2 and L3 can be parallel to the magnet arrangement line L1, or they can be arranged to have an angle of approximately 5° or less with the magnet arrangement line L1. Additionally, including the following description, the terms "along" and "as" have the same meaning in this specification as "along the magnet arrangement line L1" as described above.

[0063] More specifically, in this embodiment, two magnets 90 are separately arranged on the magnet arrangement line L1. Furthermore, two support portions 100 are separately arranged on the support portion arrangement line L2, and two support portions 100 are separately arranged on the support portion arrangement line L3. Moreover, the support portion arrangement lines L2 and L3 are parallel to the magnet arrangement line L1, with the magnet arrangement line L1 spaced between them. With this structure, the attractive force from the magnetic force acts approximately evenly on the magnet arrangement line L1, and each support portion 100 arranged on the support portion arrangement lines L2 and L3 can make approximately even contact with the wall surface 300, etc., and can be stably fixed.

[0064] (Configuration feature 2)

[0065] Further, when viewed from one of the directions along the rotation center O of the winding drum 30 (for example, the rear), the extending direction of a virtual straight line L4 (in this embodiment, coinciding with the magnet arrangement line Ll) extending from the rotation center O of the winding drum 30 to the opening center of the opening portion 23 is defined as the reference pull-out direction of the long object (the direction along the straight line L4). In addition, in this embodiment, the opening center of the opening portion 23 is the center in the width direction of the opening portion 23 when viewed from the front. Furthermore, on the basis of the above-described configuration feature 1 being satisfied, the magnet arrangement line Ll and the support portion arrangement lines L2, L3 are along the reference pull-out direction.

[0066] When the long object 200 is pulled out, the force with which the winding drum 30 is stretched in the stretching direction and the rotational torque acting by the rotation of the winding drum 30 act on the first housing 10. When the long object 200 is pulled out by these forces, there is a risk that the position of the reel 1 fixed with the magnet 90 moves. However, if the structure satisfying the above-described configuration feature 2 is satisfied, the resistance to the force acting when the long object 200 is stretched becomes high, and the movement of the reel 1 can be effectively limited.

[0067] (Configuration feature 3)

[0068] When viewed from one of the directions along the rotation center O of the winding drum 30 (for example, the rear), the magnet arrangement line Ll overlaps with a virtual straight line extending from the rotation center O of the winding drum 30 to the opening center of the opening portion 23. Thereby, the effect of suppressing the movement of the reel 1 obtained by the above-described configuration feature 2 can be further improved.

[0069] (Configuration feature 4)

[0070] When viewed from one of the directions along the rotation center O of the winding drum 30 (for example, the rear), the magnet 90 is arranged with two across the rotation center O of the winding drum. Furthermore, the support portion 100 is arranged with two on each of the support portion arrangement lines L2, L3 in a line symmetry with the magnet arrangement line Ll. Thereby, using the minimum number of magnets 90 and support portions 100, the magnet 90 and the support portion 100 can be arranged relatively balanced around the rotation center O of the winding drum 30, and stable fixation can be achieved.

[0071] (Configuration feature 5)

[0072] When viewed from one of the directions along the rotation center O of the winding drum 30 (for example, the rear), the magnet 90 is arranged outside the outer diameter of the winding drum 30 (refer to Figure 5the screw hole 14a of the first housing 10 and the position of the winding drum 30). Thus, by arranging the magnet 90 at a position separated from the center of rotation O of the winding drum 30, the moment of force opposing the rotational moment of force acting on the first housing 10 becomes high when the long article 200 is pulled out, and the effect of suppressing the movement of the reel 1 can be further improved.

[0073] In the structure of the reel 1, the structure other than the magnet 90 and the support portion 100, i.e., the structure of automatically winding and housing the long article 200, has substantially the same structure as the reel used in the past. Therefore, the durability and safety of the reel 1 of the present embodiment are good. Further, by appropriately arranging the magnet 90 and the support portion 100, the reel 1 can be easily fixed and also easily detached.

[0074] As described above, the reel 1 of the present embodiment has the support portion 100 more protruding than the magnet 90. Thus, the durability and safety of the reel 1 of the present embodiment are good, the reel 1 can be easily fixed and also easily detached, and further, a reel in which the position fixed by the magnet does not easily move when the long article 200 is pulled out can be realized. Further, by having the above-described plurality of arrangement features, the effect of the position fixed not easily moving can be further improved. Further, the support portion 100 is composed of an elastic body, so the effect of the position fixed not easily moving can be further improved.

[0075] (Modified Embodiments)

[0076] The modified embodiments are not limited to the embodiments described above, and various modifications and changes can be made, and these modified embodiments are also within the scope of the present application.

[0077] (1) In the embodiments, the magnet 90 is provided with two, and the support portion 100 is provided with four, and each arrangement is specifically described. This is not limiting, and for example, the number of magnets or the number of support portions can be increased or decreased. In this case, it is not necessary to be configured to satisfy all four arrangement features 1 to 4, and can be appropriately selected according to the usage.

[0078] Figure 6 Rear view of the reel of the modified embodiment in which the number of magnets is four. In the embodiment, the magnet 90 is provided with four, and the support portion 100 is provided with four. The magnet 90 is arranged at a position separated from the center of rotation O of the winding drum 30, and the support portion 100 is arranged at a position separated from the screw hole 14a of the first housing 10 and the position of the winding drum 30). Thus, by arranging the magnet 90 at a position separated from the center of rotation O of the winding drum 30, the moment of force opposing the rotational moment of force acting on the first housing 10 becomes high when the long article 200 is pulled out, and the effect of suppressing the movement of the reel 1 can be further improved. Figure 6In the illustrated example, four magnets 90 are provided. That is, in the transformation-type reel 1B, in addition to the two magnets 90 provided on the magnet arrangement line L1, two magnets 90 are further provided on a magnet arrangement line L11 in the previously illustrated embodiment. Here, the magnet arrangement line L11 is orthogonal to the magnet arrangement line L1. Further, in the transformation-type reel 1B, the arrangement of the support portions 100 is not changed from the previous embodiment, but the positional relationship between the support portions 100 and the additional magnets 90 satisfies the arrangement feature 1 described previously. That is, in the present embodiment, the transformation-type reel 1B has two magnets 90 provided separately on the magnet arrangement line L11. Further, two support portions 100 are provided separately on a support portion arrangement line L12, and two support portions 100 are provided separately on a support portion arrangement line L13. Moreover, the support portion arrangement line L12 and the support portion arrangement line L13 are parallel to the magnet arrangement line L11, and the magnet arrangement line L11 is interposed between the support portion arrangement line L12 and the support portion arrangement line L13. With this structure, the attractive force from the additional magnets 90 acts substantially equally on the magnet arrangement line L11, and each of the support portions 100 provided on the support portion arrangement line L12 and the support portion arrangement line L13 can substantially equally contact the wall surface 300 or the like. In this way, in the transformation-type reel 1B, the arrangement feature 1 is satisfied in two orthogonal directions, so the fixation can be more stable.

[0079] (2) In the embodiment, the example is illustrated in which the magnets 90 and the support portions 100 are provided only on the rear side of the first housing 10. Not limited thereto, for example, the magnets and the support portions can be provided on both of the front surface and the rear surface that cross the rotation center of the reel. Thereby, it is possible to fix the long object with the winding direction thereof being opposite, and to simply fix in an easy-to-use direction according to the use position. In this case, it is also possible to provide a structure corresponding to the internal thread portion 82 that can supply air from the outside on the rear surface side, and to form a structure that can properly mount a cover member.

[0080] (3) In the embodiment, in addition to the fixation method using the magnets 90, the example is illustrated in which the fixation method using the reel 1 with the hooking hole 12, and the fixation method using the reel 1 with the screw hole 13 are used. Not limited thereto, for example, it can be a mode in which the fixation method using the reel 1 with the hooking hole 12, and the fixation method using the reel 1 with the screw hole 13 cannot be used. That is, it can be configured not to have a structure in which the first housing 10 and the second housing 20 are penetrated in the front-rear direction (the direction along the rotation center O of the reel 30) by the hooking hole 12, the screw hole 13, or the like. Thereby, although the fixation method is limited to the method using the magnets, it is possible to miniaturize the outer shape of the first housing 10 and the second housing 20 to a size close to the outer diameter shape of the reel 30.

[0081] (4) In the embodiment, the support portion 100 is cited as an example of another component provided to the first case 10. The support portion 100 is not limited to this, and for example, a part or the whole of the support portion 100 can be integrated with the first case 10. In this case, the support portion 100 and the first case 10 can be integrally molded by being formed of the same resin material. Further, the support portion 100 can be prepared as another member in advance, and integrated by insert molding or two-color molding at the time of molding of the first case 10.

[0082] In addition, each of the embodiments and the modifications can be appropriately combined, but detailed description is omitted. Further, the present application is not limited to each of the embodiments described above.
