Description

[Technical Field]

[0001] The present invention relates to a winding device for wiring and piping material and a winding structure for the winding device for wiring and piping material. [Background technology]

[0002] The winding device for wiring and piping material is fixed to a fixed part, and the winding part is wound around the wiring and piping material to attach the wiring and piping material to the fixed part. Such a winding device for wiring and piping material is disclosed in Patent Document 1, for example.

[0003] The wrap-band type wire harness clamp disclosed in Patent Document 1 has a base with a band insertion / locking hole and a wrap-band extending from the base. The wrap-band has a locking protrusion at its tip. The wrap-band also has a plurality of locking recesses in its middle along its length, and a band insertion / holding ring near the base.

[0004] When using the wire harness clamp, the wrapping band is wrapped around the wire harness, and the tip of the wrapping band is inserted into the band insertion / engagement hole. The engagement projection protruding from the band insertion / engagement hole is engaged with one of the engagement recesses of the wrapping band. This causes the wrapping band to be wrapped around the wire harness and hold the wire harness in place by the wrapping band. The excess portion of the wrapping band on the tip side beyond the engagement point is overlapped with the wrapping band in the lower wound state and inserted into the band insertion / holding ring.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 08-275346 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the wire harness clamp disclosed in Patent Document 1, the tip of the winding band that exceeds the band insertion and presser ring remains as an excess portion. If this excess portion is too long, it may warp outward, degrading the aesthetic appearance, or it may not be possible to overlap it with the underlying winding band, degrading the aesthetic appearance. For this reason, the wire harness clamp disclosed in Patent Document 1 requires the operation of cutting off the excess portion that exceeds the band insertion and presser ring. [Means for solving the problem]

[0007] A winding device for wiring and piping material that solves the above problems comprises a band-shaped winding section that is wound around the wiring and piping material and has a first surface and a second surface that are opposite each other in the thickness direction of the material, and a maintaining section that is provided on the first end side of the winding section, one of both longitudinal ends, into which the second end side of the winding section wound around the wiring and piping material is inserted and which engages with a position of the winding section closer to the first end than the second end, thereby maintaining a state in which the wiring and piping material is surrounded by the winding section, and when the winding section is engaged with the maintaining section, the winding section can form an enclosing section that surrounds the wiring and piping material, and can form an excess portion at the second end side of the winding section that extends beyond the maintaining section, and the winding section has introduction ports that open on the first and second surfaces for introducing the excess portion from the outer periphery side to the inner periphery side of the enclosing section.

[0008] In a winding device for wiring and piping material, the winding portion is wound around the wiring and piping material with the second surface as the inner surface of the surrounding portion, and the excess portion is inserted from the first surface of the surrounding portion toward the second surface, and the second surface of the winding portion is provided with a gap forming portion for forming a gap between the outer surface of the surrounded wiring and piping material and the second surface, and the gap forming portion may allow the excess portion to be inserted inside the surrounding portion through the inlet.

[0009] In the winding device for wiring and piping material, the gap forming portion may form a gap that extends from the introduction port toward the second end. In a winding device for wiring / piping material, the winding portion has a fixing portion for fixing the wiring / piping material to a fixed portion, and the fixing portion may be located at a position away from the inlet toward the second end in the longitudinal direction.

[0010] In a winding device for wiring and piping material, the winding portion has a guide portion that guides the excess portion introduced inside the surrounding portion in a direction away from the second surface, and the guide portion may be provided closer to the first end in the longitudinal direction than the fixed portion, and may protrude from the second surface contiguous with an opening edge of the introduction port that is closer to the second end in the longitudinal direction.

[0011] In a winding device for wiring and piping material, the fixing portion can be fixed to the fixed portion by a fastener that penetrates the winding portion in the plate thickness direction and is driven into the fixed portion, and the winding portion has protrusions that protrude from the second surface on both sides of the fixing portion in the width direction perpendicular to the longitudinal direction, and the protrusions can form a gap between the second surface and the outer surface of the wiring and piping material.

[0012] In a winding device for wiring and piping material, the winding portion is arranged in the following order from the second end to the first end: an engaging band portion that engages with the maintaining portion, a fixing band portion that can be fixed to the fixed portion, and an introducing band portion that is provided with the introducing port; when the maintaining portion is engaged with the engaging band portion closest to the first end, the excess portion has a length such that the second end, which is the tip of the excess portion, reaches the fixing band portion; the width of the winding portion in the width direction perpendicular to the longitudinal direction is formed wider for the introducing band portion than for the engaging band portion; and the opening width of the introducing port in the width direction may be wider than the width of the winding portion at the engaging band portion.

[0013] The winding structure of a winding device for wiring and piping material that solves the above problems is a winding structure for wiring and piping material, which has a band-shaped winding portion and a retaining portion that engages with the winding portion, in which the wiring and piping material is wound by the winding portion, a second end of the winding portion is inserted into the retaining portion that is provided on a first end side of the winding portion in the longitudinal direction, and the retaining portion engages with a position of the winding portion closer to the first end than the second end, so that the state in which the wiring and piping material is surrounded by the winding portion is maintained. The gist of the present invention is that the winding structure of a winding device for wiring and piping material is such that the winding part forms an enclosing part that surrounds the wiring and piping material, and an excess part is formed on the second end side of the winding part at a portion that extends beyond the maintaining part, and the excess part is introduced from the outer periphery side to the inner periphery side of the enclosing part through an introduction port formed on the winding part closer to the second end than the maintaining part, and is sandwiched in the gap between the enclosing part and the wiring and piping material.

[0014] Regarding the winding structure of the winding device for wiring / piping material, the wiring / piping material has a covering material on the outer periphery that can be compressed in the thickness direction, and in the excess length portion, the portion sandwiched between the surrounding portion and the wiring / piping material may compress the covering material in the thickness direction.

[0015] Regarding the winding structure of the winding device for wiring and piping materials, the winding device for wiring and piping materials is fixed to the fixed portion by a fixing portion that is further toward the second end than the inlet in the winding portion, and the second end of the excess portion may reach the fixing portion.

[0016] Regarding the winding structure of a winding device for wiring / piping material, the winding portion has a first surface and a second surface that are opposite to each other in the plate thickness direction, and is wound around the wiring / piping material with the second surface as the inner surface of the surrounding portion, and the excess portion introduced into the inside of the surrounding portion through the introduction port may enter a gap between the outer surface of the wiring / piping material and the second surface formed by a gap forming portion provided on the second surface of the winding portion. [Effects of the Invention]

[0019] Hereinafter, one embodiment of a winding device for wiring and piping material and a winding structure of the winding device for wiring and piping material will be described with reference to Figs. <Wiring and piping materials> As shown in FIG. 1, a piping material 10 serving as a wiring / piping material has a pipe body 11 whose outer surface is covered with a covering material 12 that is compressible and deformable in the thickness direction. In other words, the piping material 10 has a covering material 12 that is compressible and deformable in the thickness direction on its outer periphery. The pipe body 11 is made of resin or metal. The covering material 12 is formed into a cylindrical shape from a low-strength material such as urethane foam insulation. In addition to the piping material 10, examples of wiring / piping materials include cables, refrigerant pipes, exhaust pipes, drainage pipes, etc. Wiring / piping materials may have either an uneven or smooth outer surface.

[0020] <Wiring and piping wrapping tools> As shown in FIGS. 1 and 2, the winding device 20 for wiring and piping material has a band-shaped winding portion 30 that is wound around the piping material 10, and a retaining portion 70 that engages with the winding portion 30.

[0021] <Winding section> As shown in Figures 2, 3, 4 and 5, the winding portion 30 has a first end 30a at one of its longitudinal ends and a second end 30b at the other of its longitudinal ends. The winding portion 30 also has a first surface 31 and a second surface 32 that are opposite each other in the thickness direction. The second surface 32 is the surface that faces the enclosed space 80 that surrounds the piping material 10 when the winding portion 30 surrounds the piping material 10. In the winding portion 30, the direction that is perpendicular to the longitudinal direction and along the first surface 31 and the second surface 32 is defined as the width direction. The dimension of the winding portion 30 in the width direction is defined as the "width."

[0022] The winding section 30 has a long plate-shaped connecting band 40 including the first end 30a, a long plate-shaped introducing band 43 located closer to the second end 30b than the connecting band 40, a long plate-shaped fixing band 50 located closer to the second end 30b than the introducing band 43, and a long plate-shaped engaging band 62 located closer to the second end 30b than the fixing band 50. The winding section 30 is arranged in the order of the engaging band 62, fixing band 50, introducing band 43, and connecting band 40 from the second end 30b toward the first end 30a.

[0023] <Connecting belt part> The first end 30a of the wound portion 30 is located at the first longitudinal end 40a of the connecting band portion 40, and the introduction band portion 43 is continuous with the second longitudinal end 40b of the connecting band portion 40. A maintaining portion 70 is provided at the first end 30a of the wound portion 30. The connecting band portion 40 is the portion of the wound portion 30 that extends from the first end 30a to the introduction band portion 43.

[0024] <Introductory belt> The introduction belt 43 has a first end 43a at one end in the longitudinal direction of the introduction belt 43 and a second end 43b at the other end in the longitudinal direction of the introduction belt 43. The first end 43a of the introduction belt 43 is connected to the second end 40b of the connecting belt 40. The second end 43b of the introduction belt 43 is connected to the fixing belt 50.

[0025] The width of the wound portion 30 at the introduction band 43 is wider than the width of the wound portion 30 at the connecting band 40. The introduction band 43 is wider than both ends of the connecting band 40 in the width direction. An introduction port 44 is formed near the first end 43a of the introduction band 43. The introduction port 44 is an elongated hole that extends longitudinally in the width direction of the wound portion 30. The introduction port 44 opens on the first surface 31 and the second surface 32 of the wound portion 30. A first opening width W1 of the introduction port 44 in the width direction is wider than a second opening width W2 of the introduction port 44 in the longitudinal direction of the wound portion 30.

[0026] The introduction band 43 has a guide portion 45 provided closer to the second end 30b than the introduction port 44 in the longitudinal direction of the winding portion 30. The guide portion 45 protrudes from the second surface 32 of the introduction band 43. The guide portion 45 has a guide surface 45a. The guide surface 45a is inclined so that the amount of protrusion from the second surface 32 gradually increases from the first end 30a to the second end 30b of the winding portion 30, and then gradually decreases. The guide portion 45 is provided continuous with the edge of the introduction port 44, which extends in the width direction of the winding portion 30, that is closer to the second end 30b. Therefore, the guide portion 45 protrudes from the second surface 32 continuous with the edge of the introduction port 44 that is closer to the second end 30b in the longitudinal direction of the winding portion 30. The dimension of the guide portion 45 in the width direction is the same as the first opening width W1 of the introduction port 44.

[0027] The introduction band 43 has first gap forming portions 46 located on both sides of the introduction port 44 and the guide portion 45 in the width direction. The first gap forming portions 46 protrude from the second surface 32 from the opening edge closest to the first end 30a of the introduction port 44, which extends in the width direction of the winding portion 30, to the guide portion 45. Therefore, the pair of first gap forming portions 46 are provided at positions sandwiching the introduction port 44 and the guide portion 45 from both sides in the width direction. The first gap forming portions 46 gradually increase their protrusion from the second surface 32 from the first end 30a to the second end 30b of the winding portion 30, and then, like the guide portions 45, are inclined so as to gradually decrease their protrusion amount. Therefore, the guide portion 45 gradually increases its protrusion amount at a position lower than the pair of first gap forming portions 46.

[0028] <Fixing band> The fixing band 50 has a first end 50a at one end in the longitudinal direction of the fixing band 50 and a second end 50b at the other end in the longitudinal direction of the fixing band 50. The first end 50a of the fixing band 50 is connected to the second end 43b of the introduction band 43. The first end 50a of the fixing band 50 is located at the position of the second gap forming portion 54 closest to the first end 30a among multiple second gap forming portions 54 described below. The second end 50b of the fixing band 50 is connected to the engagement band 62.

[0029] The width of the wound portion 30 at the fixing band 50 is the same as the width of the wound portion 30 at the introduction band 43. The fixing band 50 is wider than both ends of the wound portion 30 at the connecting band 40 in the width direction. 2, the fixing band 50 has a fixing portion 51 for fixing the piping material 10 to the fixed portion 100. Specifically, the fixing portion 51 can be fixed to the fixed portion 100 by a fastener 101 that penetrates the winding portion 30 in the plate thickness direction and is driven into the fixed portion 100. The above-mentioned guide portion 45 is provided closer to the first end 30a of the winding portion 30 in the longitudinal direction than the fixing portion 51.

[0030] As shown in Figures 6 and 7, the fixing portion 51 is provided in a position away from the introduction port 44 toward the second end 30b in the longitudinal direction of the winding portion 30, and is provided in the center of the winding portion 30 in the width direction. The fixing portion 51 is connected to both ends of the winding portion 30 in the width direction via multiple connecting pieces 52. The multiple connecting pieces 52 are provided at equal intervals in the longitudinal direction of the winding portion 30. In the fixing band portion 50, slits 53 are opened on the first surface 31 and the second surface 32 at positions that sandwich the connecting pieces 52 in the longitudinal direction of the winding portion 30. In other words, the slits 53 penetrate the fixing band portion 50 in the plate thickness direction. The fixing portion 51 is sandwiched from both sides in the width direction of the winding portion 30 by the multiple slits 53.

[0031] The fixed portion 51 has a first mark 611, a second mark 612, and a third mark 613 formed as recesses by stamping on the second surface 32. Therefore, the second surface 32 of the fixed portion 51 is flat. The first mark 611 is arranged at both ends of the fixed portion 51 in the longitudinal direction and at the center. The first mark 611 includes a circular mark 61a and four linear marks 61b arranged outside the circular mark 61a. The circular mark 61a is arranged at the center of the fixed portion 51 in the width direction of the wound portion 30. Two of the four linear marks 61b extend linearly in the longitudinal direction of the wound portion 30, sandwiching the circular mark 61a therebetween, and the remaining two extend linearly in the width direction of the wound portion 30, sandwiching the circular mark 61a therebetween.

[0032] The second mark 612 is arranged adjacent to the first mark 611 in the longitudinal direction of the winding portion 30. The second mark 612 is formed only by a circular mark 61a. The third mark 613 is arranged between adjacent second marks 612 in the longitudinal direction of the winding portion 30. The third mark 613 includes a circular mark 61a and two linear marks 61b arranged outside the circular mark 61a. The two linear marks 61b of the third mark 613 extend linearly in the width direction of the winding portion 30, sandwiching the circular mark 61a therebetween.

[0033] 6, the fixing band part 50 has a deformation assist groove 501 recessed from the first surface 31 at the fixed part 51. The deformation assist groove 501 extends in the width direction of the winding part 30. The deformation assist groove 501 connects the slits 53 that face each other across the fixed part 51. A plurality of deformation assist grooves 501 are provided at equal intervals in the longitudinal direction of the winding part 30.

[0034] As shown in FIGS. 3 to 5 , the fixing band 50 has second gap forming portions 54 as multiple protrusions that protrude from the second surface 32 on both sides of the fixing portion 51 in the width direction of the wound portion 30. The second gap forming portions 54 protrude from both ends of the wound portion 30 in the width direction. The second gap forming portions 54 are located outside the slits 53 in the width direction of the wound portion 30. The multiple second gap forming portions 54 are arranged side by side so as to extend in the longitudinal direction of the wound portion 30. The multiple second gap forming portions 54 are also provided at positions on the second surface 32 of the wound portion 30 away from the introduction port 44 toward the second end 30b.

[0035] The second gap forming portion 54 has a standing wall 56 that protrudes like a thin plate from the second surface 32, and a curved wall 57 that protrudes like a thin plate inward in the width direction from the tip of the standing wall 56. The standing wall 56 is elastically deformable in the width direction of the winding portion 30, with its base end as a base point. The curved wall 57 curves from the end of the standing wall 56 that protrudes from the second surface 32, sloping downward toward the second surface 32. The curved wall 57 is elastically deformable so as to approach the standing wall 56.

[0036] The multiple second gap forming portions 54 are arranged at equal intervals in the longitudinal direction of the wound portion 30. Therefore, adjacent second gap forming portions 54 in the longitudinal direction of the fixing band portion 50 in the wound portion 30 are separated by a gap. Therefore, each second gap forming portion 54 can elastically deform independently.

[0037] The second gap forming portions 54 face each other in the width direction of the winding portion 30. Therefore, the curved walls 57 face each other in the width direction of the winding portion 30. The dimension between the second gap forming portions 54 facing each other in the width direction gradually narrows from the tip side to the base end of the second gap forming portions 54. The second gap forming portions 54 face each other on both sides in the width direction of the winding portion 30 at the second end 30b, closer to the introduction port 44 in the longitudinal direction of the winding portion 30.

[0038] First gap forming portion 46, which sandwiches introduction port 44 from both sides in the width direction of winding portion 30, and second gap forming portion 54, which extends in the longitudinal direction of winding portion 30, have different shapes. Second gap forming portion 54 is elastically deformable in a direction that widens the gap between opposing surfaces in the width direction of winding portion 30, and is configured so that excess length portion 66 can be inserted by elastic deformation.

[0039] As shown in FIG. 9, when the piping material 10 is surrounded from the outer periphery by the winding portion 30, the curved wall 57 of the second gap forming portion 54 comes into contact with the outer periphery of the piping material 10. Then, a second gap T2 is defined between the outer periphery of the piping material 10 and the second surface 32 of the fixing portion 51. Here, as shown in FIG. 5, the dimension from the second surface 32 to the tip of the curved wall 57 is defined as the protruding dimension H of the second gap forming portion 54. This protruding dimension H is greater than the plate thickness of the engaging band portion 62, which will be described later. Therefore, the size of the second gap T2 formed by the second gap forming portion 54 in the radial direction of the piping material 10 is greater than the plate thickness of the engaging band portion 62.

[0040] Furthermore, with regard to the second gap T2, the size in the width direction of the wound portion 30 between the vertical walls 56 facing in the width direction differs from the size between the curved walls 57 facing in the width direction. As described above, the curved walls 57 protrude inward in the width direction from the tip of the vertical walls 56. Therefore, the size between the curved walls 57 facing in the width direction is smaller than the size between the vertical walls 56 facing in the width direction. Furthermore, the size between the curved walls 57 facing in the width direction is smaller than the width of the wound portion 30 at the engagement band portion 62.

[0041] <Engagement band> 3 and 6, the engaging strap 62 has a first end 62a at one longitudinal end and a second end 62b at the other longitudinal end. The first end 62a of the engaging strap 62 is connected to the second end 50b of the fixing strap 50. The second end 62b of the engaging strap 62 is the same as the second end 30b of the winding portion 30. The engaging strap 62 is a thin, strip-like member. Therefore, the engaging strap 62 can be easily flexibly deformed by an operator.

[0042] The width of the wound portion 30 at the engaging band 62 is narrower than the width of the wound portion 30 at the introducing band 43 and the fixing band 50, and is the same as the width of the wound portion 30 at the connecting band 40. Therefore, the width of the wound portion 30 at the introducing band 43 is wider than that at the engaging band 62. Therefore, the first opening width W1 of the introduction port 44 is wider than the width at the engaging band 62.

[0043] The engaging belt 62 extends in a belt shape with the fixing belt 50 side as its base end. A large number of belt engaging portions 63 are formed on the first surface 31 of the engaging belt 62 in the longitudinal direction of the engaging belt 62. In other words, the engaging belt 62 has a plurality of belt engaging portions 63 in the longitudinal direction of the engaging belt 62.

[0044] 8, the band engaging portion 63 has a shape in which the plate thickness decreases from the first end 62a to the second end 62b of the engaging band portion 62. The band engaging portion 63 is formed with an inclined surface 63a that slopes toward the second surface 32 as it moves from the first end 62a to the second end 62b. The band engaging portion 63 also has an engaging surface 63b that extends perpendicularly from the tip of the inclined surface 63a toward the second surface 32.

[0045] <Maintenance Department> As shown in FIG. 3, the retaining unit 70 is integrated with the first end 30a of the winding unit 30. The retaining unit 70 has a retaining unit main body 71 that defines an internal space S, and a locking unit 73 that is provided on the retaining unit main body 71. The retaining unit main body 71 has a rectangular tubular shape that opens along the longitudinal direction of the winding unit 30. The retaining unit main body 71 has a first end face 711 from which the winding unit 30 extends, and a second end face 712 on the opposite side of the first end face 711 with the retaining unit main body 71 in between.

[0046] 4 and 8, an internal space S is defined inside the maintaining portion main body 71. The maintaining portion main body 71 has, among the inner surfaces defining the internal space S, a pair of first defining surfaces 71a facing in the thickness direction of the winding portion 30, and a pair of second defining surfaces 71b facing in the width direction of the winding portion 30.

[0047] The locking portion 73 is integrally molded with one of the pair of first demarcation surfaces 71a. The locking portion 73 has a thin, long plate shape overall. The locking portion 73 has a tilting base 74 that is integral with one of the first demarcation surfaces 71a, an operating piece 75 that extends in a strip shape from the tilting base 74 so as to pass through the internal space S, and a retaining portion engaging portion 76 that protrudes from one longitudinal surface of the operating piece 75.

[0048] The tilting base 74 protrudes from one first demarcation surface 71a toward the other first demarcation surface 71a. The tilting base 74 is provided closer to the second end surface 712. The operating piece 75 extends longitudinally from the tilting base 74 in the longitudinal direction of the winding unit 30. The longitudinal side of the operating piece 75 opposite the tilting base 74 side protrudes from the first end surface 711 to the outside of the maintaining unit main body 71. The locking unit 73 can be operated by operating the part of the operating piece 75 that protrudes from the maintaining unit main body 71.

[0049] The operation piece 75, excluding the tilting base 74, is spaced downward from one of the first demarcating surfaces 71a. The operation piece 75 has a first thick surface 75a and a second thick surface 75b that are opposite to each other. The first thick surface 75a of the operation piece 75 faces one of the first demarcating surfaces 71a inside the maintenance unit main body 71, and there is a gap between the first thick surface 75a and one of the first demarcating surfaces 71a. By utilizing this gap, the operation piece 75 can be operated to move the first thick surface 75a closer to one of the first demarcating surfaces 71a. This operation causes the operation piece 75 to tilt around the tilting base 74 as a base point.

[0050] The retaining portion engaging portion 76 protrudes from the second plate thickness surface 75b of the operating piece 75 toward the other first demarcating surface 71a. The retaining portion engaging portion 76 extends over the entire operating piece 75 in the short side direction.

[0051] The retaining unit engaging portion 76 has an engaging surface 76a that is perpendicular to the second thick surface 75b, and an inclined surface 76b that connects the engaging surface 76a and the second thick surface 75b. The inclined surface 76b is inclined so as to approach the second thick surface 75b from the first end surface 711 toward the second end surface 712 of the retaining unit main body 71.

[0052] When the operating piece 75 is not operated, the opening width between the retaining portion engaging portion 76 and the other first demarcating surface 71 a is the minimum opening width. When the operating piece 75 is operated and the first plate thickness surface 75 a is brought close to one first demarcating surface 71 a, the opening width between the retaining portion engaging portion 76 and the other first demarcating surface 71 a is the maximum opening width.

[0053] <Method of supporting piping materials using a winding tool for wiring and piping materials> Next, a method for supporting the piping material 10 using the winding device 20 for wiring and piping material will be described. As shown in FIG. 9 , the worker positions the first surface 31 of the fixing band 50 against the fixing surface 100a of the fixed part 100. Next, the worker uses a driving tool (not shown) to drive the fastener 101 from the second surface 32 toward the fixed part 51. At this time, the worker aligns the driving tool using one of the circular marks 61a of the first mark 611 to the third mark 613 on the fixed part 51 as an index. For example, the worker drives the fastener 101 into the fixed part 51 using the first mark 611, which is located in the center of the fixed part 51 in the longitudinal direction, as an index. Then, the fastener 101 penetrates the fixed part 51 in the plate thickness direction and is driven into the fixing surface 100a of the fixed part 100. As a result, the wiring and piping winding device 20 is fixed to the fixed part 100. The winding device 20 for wiring and piping material is fixed to the fixed part 100 so that the longitudinal direction of the winding part 30 extends in the vertical direction.

[0054] Next, the worker places the piping material 10 to the side of the second gap forming portion 54 of the winding device 20 for wiring and piping material, and grasps the engaging band portion 62 and moves it toward the retaining portion 70. This causes the winding portion 30 to deform into an arc shape with the second surface 32 facing inward.

[0055] At this time, the deformation of the fixing part 51 is assisted by the multiple deformation assist grooves 501. The operator inserts the tip of the engaging strap 62, i.e., the second end 30b of the winding part 30, into the internal space S from the second end surface 712 side of the maintaining body 71. Then, the inclined surface 63a of the strap engaging part 63 pushes up the inclined surface 76b of the maintaining engagement part 76. This allows the engaging strap 62 to be fed into the internal space S. When the feeding of the engaging strap 62 into the internal space S is stopped, the engaging surface 76a of the maintaining engagement part 76 and the engaging surface 63b of the strap engaging part 63 face each other. Therefore, even if the engaging strap 62 moves in the direction opposite to the feeding direction into the internal space S, the engaging surface 76a of the maintaining engagement part 76 and the engaging surface 63b of the strap engaging part 63 engage with each other. This engagement restricts movement of the engaging belt portion 62 in the direction opposite to the direction in which the engaging belt portion 62 is fed into the internal space S. In other words, the engaging belt portion 62 of the winding portion 30 and the retaining portion engaging portion 76 of the retaining portion 70 engage with each other.

[0056] When the winding portion 30 and the retaining portion 70 are engaged with each other, the connecting band portion 40, the introducing band portion 43, the fixing band portion 50, and the engaging band portion 62 form a surrounding portion 81 that surrounds the piping material 10 from the outer periphery of the covering material 12. At the same time, a surrounding space 80 is defined inside the surrounding portion 81. At this time, the winding portion 30 is wound around the piping material 10 with the second surface 32 serving as the inner surface of the surrounding portion 81. The piping material 10 is supported from below by the winding portion 30 that forms the surrounding portion 81. Therefore, the winding device 20 for wiring and piping material is provided on the first end 30a side of the winding portion 30, and has a maintaining portion 70 into which the second end 30b side of the winding portion 30 wound around the piping material 10 is inserted, engaging at a position closer to the first end 30a than the second end 30b of the winding portion 30, thereby maintaining the state in which the winding portion 30 surrounds the piping material 10.

[0057] When the surrounding portion 81 is formed, the first gap forming portions 46 are located on both sides of the inlet 44 in the width direction of the winding portion 30 and protrude toward the inside of the surrounding portion 81. The second gap forming portions 54 are located on both sides of the fixing portion 51 in the width direction of the winding portion 30 and protrude toward the inside of the surrounding portion 81. When the surrounding portion 81 is formed, the first gap forming portions 46 and the second gap forming portions 54 of the winding portion 30 each contact a portion of the outer circumferential surface of the coating material 12. Then, the first gap forming portions 46 secure a first gap T1 between the second surface 32 located around the inlet 44 and the outer circumferential surface of the coating material 12, and the second gap forming portions 54 form a second gap T2 between the outer circumferential surface of the coating material 12 and the second surface 32 of the fixing portion 51. Therefore, in the winding section 30, a first gap forming portion 46 is provided on the second surface 32, which forms a first gap T1 between the outer surface of the surrounded piping material 10 and the second surface 32. In addition, in the winding section 30, a second gap forming portion 54 is also provided on the second surface 32, which forms a second gap T2 between the outer surface of the surrounded piping material 10 and the second surface 32. This second gap forming portion 54 forms the second gap T2 extending from the introduction port 44 toward the second end 30b of the winding section 30.

[0058] Furthermore, when the winding portion 30 is engaged with the maintaining portion 70, an excess portion 66 is formed on the second end 30b side of the winding portion 30 at a portion extending beyond the maintaining portion 70. Therefore, when the winding portion 30 is engaged with the maintaining portion 70, the winding portion 30 can form a surrounding portion 81 that surrounds the piping material 10, and can also form an excess portion 66 on the second end 30b side of the winding portion 30 at a portion extending beyond the maintaining portion 70.

[0059] As described above, the winding portion 30 is provided with the engaging band 62, the fixing band 50, and the introduction band 43 lined up in this order from the second end 30b toward the first end 30a. When the retaining portion 70 is engaged with the engaging band 62 at the portion closest to the first end 30a, the excess portion 66 has a length such that the second end 30b, which is the tip of the excess portion 66, reaches the fixing portion 51 of the fixing band 50.

[0060] The excess length portion 66 is disposed on the outer peripheral side of the surrounding portion 81 so as to cover the first surface 31 of the winding portion 30. In addition, the winding portion 30 has an inlet 44 that opens to the first surface 31 and the second surface 32, for introducing the excess length portion 66 from the outer peripheral side to the inner peripheral side of the surrounding portion 81.

[0061] Then, as shown in FIG. 10 , the worker inserts the excess length portion 66 into the introduction port 44 from the second end 30b side. Therefore, in the winding device 20 for wiring and piping material, the first gap forming portion 46 allows the excess length portion 66 to be inserted into the inside of the surrounding portion 81 through the introduction port 44. The excess length portion 66 is inserted from the first surface 31 toward the second surface 32 of the surrounding portion 81. Then, the first surface 31 of the excess length portion 66 contacts the guide surface 45a of the guide portion 45. The guide surface 45a of the guide portion 45 guides the excess length portion 66 introduced into the inside of the surrounding portion 81 in a direction away from the second surface 32, i.e., toward the piping material 10. Furthermore, the excess length portion 66 introduced into the inside of the surrounding portion 81 through the introduction port 44 is inserted into the first gap T1 formed by the first gap forming portion 46. When the surplus length portion 66 is guided by the guide portion 45, the pair of first gap forming portions 46 restrains the surplus length portion 66 from moving in the width direction of the wound portion 30.

[0062] Then, with the tip side of the excess length portion 66 introduced into the enclosing portion 81 from the introduction port 44, the operator presses the engaging band 62, on the side of the first end 30a rather than the retaining portion 70, toward the direction passing through the internal space S. This allows the engaging band 62 to be sent in the direction passing through the internal space S, and also makes it possible to further narrow the enclosed space 80 of the enclosing portion 81. Therefore, the engaging band 62 has the rigidity to allow the retaining portion 70 to pass by pressing the side of the first end 30a rather than the retaining portion 70, and to narrow the enclosed space 80.

[0063] Furthermore, the further the engaging band 62 is pressed away from the retaining portion 70, the longer the excess length portion 66 becomes. When the worker presses the engaging band 62, the inclined surface 63a of the band engaging portion 63 pushes up the inclined surface 76b of the retaining portion engaging portion 76. This causes the engaging band 62 to be sent further into the internal space S.

[0064] As the enclosed space 80 narrows, the second surface 32 of the enclosed portion 81 in the portion other than the second gap forming portion 54 approaches the outer peripheral surface of the covering material 12. As a result, the curvature of the enclosed portion 81 decreases. At this time, the worker gradually decreases the curvature of the enclosed portion 81 so as not to damage the covering material 12 by the enclosed portion 81.

[0065] Furthermore, as the enclosed space 80 narrows, the excess length portion 66 moves from the introduction port 44 toward the fixed portion 51. The excess length portion 66 is fed along the outer peripheral surface of the coating material 12 and inserted into the second gap T2 formed by the multiple second gap forming portions 54. When the excess length portion 66 is inserted between the curved walls 57 of the winding portion 30 that face each other in the width direction, the excess length portion 66 presses the curved walls 57 of the winding portion 30 that face each other in the width direction outward in the width direction. As a result, the excess length portion 66 passes through the second gap T2 while elastically deforming the second gap forming portions 54 outward in the width direction. In the second gap T2, the second surface 32 of the excess length portion 66 contacts the outer peripheral surface of the coating material 12 and moves along the outer peripheral surface of the coating material 12. Therefore, even when the surrounding space 80 of the surrounding portion 81 is narrowed, the second gap forming portion 54 ensures the second gap T2 into which the excess length portion 66 can be inserted.

[0066] When the excess length portion 66 is inserted between the opposing upright walls 56 of the winding portion 30 in the width direction, the excess length portion 66 passes through the second gap T2 without pressing the opposing upright walls 56 of the winding portion 30 outward in the width direction. In this case, the excess length portion 66 does not move along the outer peripheral surface of the covering material 12, but moves while contacting the surface of the curved wall 57 facing the second surface 32.

[0067] As shown in Figure 11, when the excess length portion 66 is fed inside the surrounding portion 81, a portion of the excess length portion 66 is inserted inside the surrounding portion 81 and between the outer surface of the covering material 12 and the second surface 32, and the piping material 10 is held in the winding device 20 for wiring and piping material.

[0068] At this time, feeding of the engaging band 62 into the internal space S is stopped. Then, the engaging surface 76a of the retaining portion engaging portion 76 engages with the engaging surface 63b of the band engaging portion 63. In other words, the retaining portion 70 engages with the engaging band 62 at a midpoint in the longitudinal direction. This engagement restricts movement of the engaging band 62 in the direction opposite to the feeding direction of the engaging band 62 into the internal space S. Therefore, the retaining portion 70 has the internal space S through which the engaging band 62 of the winding portion 30 passes, and the band engaging portion 63 that allows, by displacement, movement of the engaging band 62 passing through the internal space S in a direction narrowing the enclosed space 80, while engaging with the engaging band 62 to restrict movement in a direction widening the enclosed space 80.

[0069] As a result, the state in which the surrounding portion 81 surrounds the piping material 10 is maintained. Then, with the piping material 10 surrounded by the surrounding portion 81, the piping material 10 is held by the winding device 20 for wiring and piping material. In other words, the winding structure of the winding device 20 for wiring and piping material is completed.

[0070] <Winding structure of winding tool for wiring and piping materials> 2 and 11, the winding structure of the winding device 20 for wiring and piping material is formed by the winding device 20 for wiring and piping material having a band-shaped winding portion 30 and a retaining portion 70 that engages with the winding portion 30. In the winding structure, the piping material 10 is wound by the winding portion 30. In addition, in the winding structure, the second end 30b of the winding portion 30 is inserted into the retaining portion 70 provided on the first end 30a side of the winding portion 30, and the retaining portion 70 engages with the winding portion 30 at a position closer to the first end 30a than the second end 30b, thereby maintaining the piping material 10 surrounded by the winding portion 30.

[0071] In the wound structure, a surrounding portion 81 is formed by the winding portion 30 to surround the piping material 10, and an excess portion 66 is formed on the second end 30b side at a portion extending beyond the maintaining portion 70. In the wound structure, the excess portion 66 is introduced from the outer periphery to the inner periphery of the surrounding portion 81 at an inlet 44 formed on the winding portion 30 closer to the second end 30b than the maintaining portion 70, and is sandwiched between the surrounding portion 81 and the coating material 12 of the piping material 10. In the wound structure, the elastic deformation of the excess portion 66 compresses the coating material 12 in the thickness direction at the portion of the excess portion 66 sandwiched between the surrounding portion 81 and the coating material 12 of the piping material 10.

[0072] <Operation of the embodiment> In the winding structure of winding device 20 for wiring and piping material, excess length 66 is introduced from the outer periphery side to the inner periphery side of surrounding portion 81 by being inserted into introduction port 44. Therefore, excess length 66 is not deformed so as to be warped on the outer periphery side of surrounding portion 81 or to be deformed so as to protrude from the outer periphery side of surrounding portion 81.

[0073] According to the above embodiment, the following effects can be obtained. (1) The winding portion 30 of the winding device 20 for wiring and piping material has an introduction port 44 formed therein for introducing the excess length portion 66 from the outer periphery side to the inner periphery side of the surrounding portion 81. When the excess length portion 66 is inserted into the introduction port 44, the excess length portion 66 is introduced from the outer periphery side to the inner periphery side of the surrounding portion 81. As a result, the tip portion of the excess length portion 66, including at least the second end 30b, is positioned inside the surrounding portion 81. Therefore, even without cutting the excess length portion 66, the tip portion of the excess length portion 66 does not bend outward on the outer periphery side of the surrounding portion 81, and the excess length portion 66 does not lift up on the outer periphery side of the surrounding portion 81. As a result, the aesthetic deterioration caused by the excess length portion 66 can be suppressed without cutting the excess length portion 66.

[0074] (2) A first gap forming portion 46 is formed in the winding portion 30 of the winding device 20 for wiring and piping material. The first gap forming portion 46 is provided at a position on the second surface 32 of the winding portion 30 that sandwiches the inlet 44 in the width direction. The first gap forming portion 46 forms a first gap T1 between the outer surface of the surrounded piping material 10 and the second surface 32 that surrounds the inlet 44. The excess length portion 66 introduced into the surrounding portion 81 through the inlet 44 is inserted into this first gap T1. As a result, the first gap T1 is formed by the first gap forming portion 46, which prevents the inlet 44 from being blocked by the piping material 10. Therefore, even when the surrounding portion 81 surrounds the piping material 10, the excess length portion 66 can be inserted into the inlet 44.

[0075] Then, when the excess length portion 66 inserted into the introduction port 44 is sent further inside the surrounding portion 81, the first gap forming portion 46 can move it so as to eliminate the gap formed by deforming the surrounding portion 81 and the space between the piping material 10 and the wound portion 30. Furthermore, the first gap forming portion 46 allows the excess length portion 66 to be inserted into the introduction port 44 without having to move the piping material 10 within the surrounding portion 81 to open the introduction port 44.

[0076] (3) The second gap forming portion 54 extends in the longitudinal direction of the wound portion 30. Therefore, the second gap forming portion 54 can secure the second gap T2 into which the excess length portion 66 can be inserted along the direction surrounding the piping material 10. Therefore, by securing the second gap T2 with the second gap forming portion 54, the excess length portion 66 can continue to be fed in the circumferential direction of the covering material 12.

[0077] (4) The winding portion 30 has a fixing portion 51 for fixing the piping material 10 to the fixed portion 100. The fixing portion 51 is provided at a position away from the inlet 44 toward the second end 30b in the longitudinal direction of the winding portion 30. Therefore, when the winding device for wiring and piping material 20 is fixed to the fixed portion 100 by the fixing portion 51, even if the excess length portion 66 has a length that causes it to interfere with the fixed portion 100, the excess length portion 66 can be inserted inside the surrounding portion 81 at a position before it interferes with the fixed portion 100. Furthermore, because it is possible to prevent the excess length portion 66 from interfering with the fixed portion 100, there is no need to cut the excess length portion 66 even if the surrounding space 80 inside the surrounding portion 81 is narrowed to the extent that the excess length portion 66 interferes with the fixed portion 100.

[0078] (5) The winding portion 30 has a guide portion 45. The guide portion 45 is located closer to the first end 30a than the fixed portion 51 in the longitudinal direction of the winding portion 30, and protrudes from the second surface 32, continuing from the opening edge of the introduction port 44 that is closer to the second end 30b in the longitudinal direction. Therefore, the excess length portion 66 inserted into the introduction port 44 is guided by the guide portion 45 so as to move away from the second surface 32 without interfering with the fixed portion 51.

[0079] (6) The winding portion 30 is provided with the engaging band 62, the fixing band 50, and the introduction band 43 arranged in this order from the second end 30b toward the first end 30a. When the retaining portion 70 is engaged with the engaging band 62 at the position closest to the first end 30a, the excess length 66 has a length such that the second end 30b, which is the tip of the excess length 66, reaches the fixing band 50. Even when such a long excess length 66 is formed, the first opening width W1 of the introduction port 44 is wider than the width of the engaging band 62. Therefore, the width of the introduction band 43 can be wider than the width of the engaging band 62, and the first opening width W1 of the introduction port 44 can be widened. This allows the engaging band 62 to be inserted into the introduction port 44 without twisting, making it easier to insert and introduce the excess length 66 into the enclosing portion 81.

[0080] (7) The piping material 10 has the covering material 12 on its outer periphery, which is compressible in the thickness direction. The portion of the excess length portion 66 sandwiched between the surrounding portion 81 and the covering material 12 compresses the covering material 12 in the thickness direction. The restoring force of the covering material 12 from the compressive deformation urges the tip side of the excess length portion 66 toward the wound portion 30. This allows the surrounding portion 81 to hold the piping material 10 in an appropriate manner.

[0081] (8) The plurality of second gap forming portions 54 are elastically deformable. Therefore, when the excess length portion 66 is inserted into the second gap T2, the second gap forming portions 54 can be elastically deformed by the excess length portion 66. As a result, the excess length portion 66 can be continuously fed into the second gap T2.

[0082] (9) The winding section 30 has a plurality of second gap forming sections 54. Each second gap forming section 54 is elastically deformable in the width direction of the winding section 30. Therefore, when the excess length portion 66 is inserted between the curved walls 57 facing each other in the width direction, the second gap forming sections 54 are elastically deformed, thereby allowing the excess length portion 66 to move in the second gap T2. For example, compared to when the second gap forming sections 54 are in the shape of a continuous plate, the second gap forming sections 54 are more likely to elastically deform. This makes it easier for the excess length portion 66 to move in the second gap T2, and as a result, the excess length portion 66 can continue to be fed in the circumferential direction of the coating material 12.

[0083] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The first gap forming portion 46 may be omitted. The second gap forming portion 54 may also be omitted. If neither the first gap forming portion 46 nor the second gap forming portion 54 is present, the tip of the excess length portion 66 is inserted in advance between the piping material 10 and the second surface 32 before the piping material 10 is tightened by the surrounding portion 81. Then, the excess length portion 66 is fed in while tightening the piping material 10 so as to reduce the diameter of the entire surrounding portion 81.

[0084] The first gap forming portion 46 may be formed as a continuous long plate extending from the introduction band 43 to the fixing band 50 and may serve as a substitute for the second gap forming portion 54 . The second gap forming portions 54 may be non-elastically deformable. In this case, it is preferable that the dimension between the second gap forming portions 54 facing each other in the width direction is greater than the width of the excess length portion 66.

[0085] The winding structure of the above-described winding device 20 for wiring and piping material allows the excess length 66 to be inserted into the enclosed space 80 through the inlet 44 by compressing and deforming the covering material 12, even if the inlet 44 is covered by the covering material 12. However, as an alternative to the winding structure, the winding structure can also be applied to a pipe 11 whose outer surface is not covered by a covering material 12 that is compressible and deformable in the thickness direction. Even in a pipe 11 that is not covered by a covering material 12 and whose outer surface is hard and cannot be compressed and deformed, the first gap forming portion 46 can separate the inner surface of the portion where the inlet 44 is formed from the outer surface of the pipe 11. This separation reliably forms the first gap T1 that allows the tip of the excess length 66 to be inserted into the enclosed space 80 through the inlet 44.

[0086] The winding device for wiring and piping material 20 may be fixed to the fixed part 100 by driving fasteners 101 into the fixing part 51 at multiple locations offset in the longitudinal direction of the winding part 30. In this configuration, the winding device for wiring and piping material 20 can be firmly fixed to the fixed part 100.

[0087] When the surrounding portion 81 surrounds the pipe material 10, it is not necessary to tighten it to the extent that the covering material 12 of the pipe material 10 is compressed. The number of second gap forming portions 54 provided in the longitudinal direction of the wound portion 30 may be more or less than that in the embodiment.

[0088] The length of the engaging band 62 may be changed to change the length of the formable excess portion 66. For example, the length of the engaging band 62 may be adjusted so that the second end 30b does not reach the fixing band 50 when the retaining portion 70 is engaged with the engaging band 62 at the portion closest to the first end 30a.

[0089] The winding portion 30 does not have to have the guide portion 45. The winding device 20 for wiring and piping material does not have to have the fixing part 51. In this case, the winding device 20 for wiring and piping material is fixed to the fixed part 100 using a fixing member separate from the winding device 20 for wiring and piping material.

[0090] The surrounding portion 81 of the winding device 20 for wires and piping may surround only the wires, or may surround both the wires and the piping 10 . [Explanation of symbols]
