Description

[Technical field]

[0001] The present invention relates to an auxiliary supporting member. [Background technology]

[0002] For example, a long body support is used to suspend and support a long body such as an air conditioning pipe or a drain pipe. When using such a long body support, an auxiliary support member may be interposed between the support part of the long body support and the long body supported by it. The auxiliary support member is configured to have a support length longer than the support width of the support part in the longitudinal direction of the long body, and supports the long body in a distributed manner over a wide support area. This makes it possible to support the long body in a stable position, and to suppress a decrease in heat retention performance due to the collapse of the heat retention material when the long body includes a heat retention material covering the pipe.

[0003] One example of such an auxiliary support member is disclosed in Japanese Patent Laid-Open Publication No. 2009-133430 (Patent Document 1). The auxiliary support member (suspension hardware auxiliary member 10) of Patent Document 1 has a protrusion (protrusion 11a) on the underside of an arc-shaped support plate. The protrusion is fitted into a hole (perforation 30a) provided in the support part (band part 30) of the long body support (suspension hardware 20), so that the auxiliary support member can be attached and detached to the support part of the long body support. The fitting of the hole and the protrusion determines the position of the auxiliary support member relative to the long body support.

[0004] However, the auxiliary support member in Patent Document 1 is intended to be used with a dedicated elongated body support having a hole in the support part, and therefore, when used with a general-purpose elongated body support (a support for elongated bodies without a hole in the support part), the tip of the protrusion abuts against the inner surface of the support part, causing the surrounding area of ​​the protrusion to float up from the support part, resulting in poor stability.

[0005] [Patent Document 1] JP 2009-133430 A Summary of the Invention [Problem to be solved by the invention]

[0006] It is desirable to realize an auxiliary support member that can be stably attached to a general-purpose elongated body support tool and can be appropriately positioned. [Means for solving the problem]

[0007] The auxiliary supporting member according to the present invention comprises: A support auxiliary member interposed between a support portion of a support device for a long body that supports a long body by suspending the long body and the long body, A support plate extending along the longitudinal direction of the elongated body and having a through hole; an elastic holding piece that is an elastic body provided in a cantilever state on the lower surface of the support plate and that holds the support part; A locking portion provided on an upper surface of the support plate, The base end side of the elastic holding piece clamps the support part between itself and the lower surface of the support plate, and the tip side passes through the through hole and is engaged with the engaging part on the upper surface side of the support plate.

[0008] According to this configuration, the elastic holding piece provided on the auxiliary support member holds the support part of the elongated body support from the underside, so that the support plate can be placed in surface contact with the support part of the elongated body support. Therefore, the auxiliary support member can be stably attached to the support part of the elongated body support without any inconvenience such as a specific part floating up. In addition, since the elastic holding piece provided in a cantilever state holds the support part between the base end side and the underside of the support plate, it is possible to make it difficult for the position to shift due to the sliding resistance between the support part. At that time, the tip side of the elastic holding piece can be engaged with the engaging part on the upper surface side of the support plate to increase the pressure contact force of the elastic holding piece against the support part, and the sliding resistance can be increased to make it even more difficult for the position to shift. Therefore, it is possible to realize an auxiliary support member that can be stably attached to a general-purpose elongated body support and can be appropriately positioned.

[0009] Preferred embodiments of the present invention will be described below. However, the scope of the present invention is not limited to the preferred embodiments described below.

[0010] In one embodiment, It is preferable that the through hole is provided at a position overlapping the elastic retaining piece in a plan view, and the engaging portion is provided widthwise adjacent to a portion of the through hole on the tip side of the elastic retaining piece.

[0011] According to this configuration, the tip side of the elastic retaining piece can be easily guided to the upper surface side of the support plate through the through hole by simply lifting the tip side of the elastic retaining piece in the vertical direction. After the tip side of the elastic retaining piece is guided to the upper surface side of the support plate, it can be easily locked to the locking portion by simply displacing it in the width direction. Therefore, the tip side of the elastic retaining piece can be easily locked to the locking portion on the upper surface side of the support plate through the through hole.

[0012] In one embodiment, It is preferable that the through hole has a narrow portion having a width corresponding to the width of the elastic retaining piece, and a wide portion that is adjacent to the engaging portion in the longitudinal direction and is wider than the narrow portion.

[0013] According to this configuration, by making the narrow portion have a width corresponding to the width of the elastic retaining piece, it is possible to minimize the decrease in strength of the entire support auxiliary member while allowing the elastic retaining piece to pass through. Also, by having a relatively wide portion adjacent to the locking portion in the longitudinal direction of the elongated body, it is possible to appropriately displace the elastic retaining piece in the width direction to lock the tip side to the locking portion.

[0014] In one embodiment, The support plate has a plurality of ribs extending along the longitudinal direction, It is preferable that the locking portion is configured to include side surfaces of some of the plurality of rib portions.

[0015] According to this configuration, the strength of the support plate can be increased by the presence of multiple rib portions. In addition, by using a portion of such a rib portion and having its side surface double as the locking portion, the configuration can be simplified compared to the case where a locking portion is provided separately. In addition, most of the tip of the elastic retaining piece can be contained within the range of the height of the rib portion, and while the elastic retaining piece is locked to the locking portion on the upper surface side of the support plate, the actual upward protrusion can be kept as small as possible. Therefore, the long object can be stably supported.

[0016] In one embodiment, It is preferable that the thickness of the elastic holding piece on the tip side is thinner than that on the base side.

[0017] According to this configuration, the relatively thin tip end of the elastic retaining piece can be easily elastically deformed to engage with the engaging portion on the upper surface side of the support plate. Also, the relatively thick base end of the elastic retaining piece can stably hold the support portion between the bottom surface of the support plate. Therefore, positioning with respect to the elongated body support can be more appropriately performed.

[0018] In one embodiment, It is preferable that the elastic holding piece is bent so that its tip is positioned on the support plate side.

[0019] According to this configuration, the tip side of the elastic holding piece provided on the lower surface of the support plate can be easily locked to the locking portion on the upper surface side of the support plate.

[0020] In one embodiment, It is preferable that the support plate be provided on at least one side in the width direction with an engagement portion that is engageable with the support portion from both sides in the longitudinal direction.

[0021] According to this configuration, the engaging portions engage with the support portions from both longitudinal sides of the elongated body on at least one side in the width direction, so that the auxiliary support member can be positioned in the longitudinal direction relative to the elongated body support tool.

[0022] In one embodiment, the support plate has a pair of slits formed from its side edges on at least one side in the width direction so as to have portions extending at least along the width direction at intervals corresponding to the length of the longitudinal direction of the support portion; It is preferable that the engagement portion be formed by an inner edge of a portion of the support plate that is located outside the pair of slits in the longitudinal direction.

[0023] According to this configuration, by simply forming a pair of slits extending from the side edges on at least one side in the width direction of the support plate, it is possible to easily provide an engagement portion that can engage with the support portion from both longitudinal sides of the elongated body. Thus, with a simple configuration, it is possible to position the auxiliary support member in the longitudinal direction relative to the elongated body support tool.

[0024] In one embodiment, It is preferable that the distance between the pair of slits at the side edge positions of the support plate is shorter than the length of the support portion in the longitudinal direction.

[0025] According to this configuration, it is possible to prevent the auxiliary support member from coming off after it has been attached to the elongated body support tool. Also, even before the tip end of the elastic retaining piece is locked in the locking portion and firmly held in place, the auxiliary support member can be temporarily fixed to the elongated body support tool.

[0026] In one embodiment, It is preferable that a protrusion protruding from the support plate toward the lower surface side is provided adjacent in the longitudinal direction to one of the pair of slits that is located on the base end side of the elastic holding piece in the longitudinal direction.

[0027] According to this configuration, when the auxiliary support member is slid along the longitudinal direction of the elongated body relative to the elongated body support tool, the protrusion can function as a kind of stopper. In other words, the protrusion abuts against the elongated body support tool, making it easy to align the auxiliary support member in the longitudinal direction relative to the elongated body support tool.

[0028] In one embodiment, the support plate has a central portion located between the pair of slits and a pair of outer portions located outside the pair of slits in the longitudinal direction, It is preferable that when attached to the elongated body support tool, the curvature of the pair of outer regions is smaller than the curvature of the central region.

[0029] With this configuration, the support plate is stably placed along the support for the long body at the center, while a pair of outer regions with relatively small curvatures can engage with the support for the long body from both longitudinal sides of the long body. Therefore, the support plate can be stably attached to the support for the long body and can be appropriately positioned in the longitudinal direction of the long body.

[0030] In one embodiment, The elastic retaining piece further includes a support piece portion provided on a lower surface of the support plate at a position of a middle portion of the elastic retaining piece, It is preferable that, in a state in which the elastic holding piece is supported laterally by the support piece portion, a portion of the elastic holding piece on the tip side beyond the support piece portion is locked to the locking portion.

[0031] According to this configuration, by adjusting the installation position of the support piece, when the elastic retaining piece is engaged with the engagement part, the part of the elastic retaining piece from the base end to the support piece can be aligned in the longitudinal direction of the elongated body. Therefore, the attachment of the auxiliary support member to the elongated body support tool can be further stabilized. In addition, with this configuration, the elastic retaining piece is deflected more greatly between the support piece and the engagement part, and a larger tension acts, so that the attachment of the auxiliary support member can be further stabilized.

[0032] The long body support unit according to the present invention comprises: a long body support device that supports the long body in a suspended state; and any one of the auxiliary support members described above.

[0033] According to this configuration, when the long body is supported by the long body support tool, the auxiliary support member can be stably attached to the long body support tool at an appropriate position. By interposing the auxiliary support member between the long body support tool and the long body, the long body can be supported in a distributed manner over a wide support area, and the long body can be supported in a stable position. Furthermore, for example, when the long body includes a heat-insulating material covering a pipe, a decrease in heat-insulating performance due to the collapse of the heat-insulating material can be suppressed.

[0034] Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which are given with reference to the drawings. [Brief description of the drawings]

[0036] [First embodiment] A first embodiment of the auxiliary support member and long body support unit will be described with reference to the drawings. As shown in Fig. 1, the long body support unit 100 of this embodiment is a unit for suspending and supporting the long body 8, and includes a long body support tool 6 for suspending and supporting the long body 8, and an auxiliary support member 1 used together with the long body support tool 6. The auxiliary support member 1 is used by being interposed between the long body 8 and a support part 61 of the long body support tool 6 for the long body 8.

[0037] The long body support 6 is attached to a suspension bolt (not shown) suspended from the ceiling, and supports the long body 8 in a horizontal position. The suspension bolts are arranged along the installation direction of the long body 8. A plurality of suspension bolts are installed at a predetermined interval at a plurality of locations along the installation direction of the long body 8, and the long body support 6 attached to each suspension bolt supports the long body 8 in a suspended state over the entire installation direction.

[0038] The long body 8 has a long structure extending in one direction, such as a linear body, a tubular body, or a band-like body. Examples of such long body 8 include pipes and electric wires. As an example, the long body 8 of this embodiment is a pipe for an air conditioner, and includes a metal pipe member 81 that forms a refrigerant path, and a covering member 82 (a heat retaining material or insulating material made of urethane foam, glass wool, or the like) that covers the periphery of the pipe member 81.

[0039] The elongated body support 6 includes a support portion 61 that supports the elongated body 8, and an attachment portion 63 for attachment to a hanging bolt. The elongated body support 6 of this embodiment further includes a lid portion (not shown). The support portion 61, the attachment portion 63, and the lid portion are each made of a metal plate-like member.

[0040] The support part 61 is formed in a substantially U-shape. The support part 61 supports the long body 8 from below with a bottom part curved in an arc shape. The attachment part 63 is integrated with the support part 61 by using a fastening means such as a rivet. The attachment part 63 includes a pair of hook parts that are engaged with the suspension bolt at different positions in the axial direction. The entire long body support 6 is attached to the suspension bolt by engaging each of the hook parts with the threads on the outer surface of the suspension bolt. The lid part is connected to the support part 61 so as to be freely opened and closed. The lid part can accommodate the long body 8 in the support part 61 in a position where the upper opening of the support part 61 is left open (open position). After the long body 8 is accommodated in the support part 61, the lid part assumes a position where the upper opening of the support part 61 is closed (closed position) to prevent the long body 8 from coming out.

[0041] As shown in FIG. 1, the auxiliary support member 1 is attached to the support part 61 of the elongated body support 6 when in use. The auxiliary support member 1 is configured to have a support length in the longitudinal direction L of the elongated body 8 that is longer than the support width of the support part 61 of the elongated body support 6. The auxiliary support member 1 is disposed along the longitudinal direction L of the elongated body 8 so as to extend on both sides of the longitudinal direction L relative to the support part 61. By dispersing and supporting the elongated body 8 over a wide support area, the elongated body 8 can be supported in a stable position and performance degradation due to crushing of the covering member 82 can be suppressed.

[0042] 2 to 5, the auxiliary support member 1 includes a support plate 10, an elastic holding piece 20, a locking portion 30, and an engagement portion 40. These are integrally formed using an elastic synthetic resin such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, urethane, etc.

[0043] The support plate 10 is a plate-like member that constitutes the main part of the auxiliary support member 1, and extends along the longitudinal direction L of the elongated body 8 when attached to the support part 61 of the elongated body support 6. Since the support plate 10 is attached so that its longitudinal direction is along the longitudinal direction L of the elongated body 8, in the following description, the longitudinal direction of the support plate 10 will also be referred to as the "longitudinal direction L". Moreover, the short side direction of the support plate 10 perpendicular to the longitudinal direction L will be referred to as the "width direction W".

[0044] The support plate 10 is mainly composed of a plate body 11. The plate body 11 is formed in a rectangular shape in a plan view (when viewed in the up-down direction) at the center part in the width direction W. One surface of the plate body 11, the upper surface 11a, serves as a support surface on which the elongated body 8 is placed when the plate body is attached to the elongated body support tool 6. The other surface of the plate body 11, the lower surface 11b, serves as a supported surface that is received and supported by the support part 61 when the plate body is attached to the elongated body support tool 6.

[0045] In this embodiment, a plurality of upper rib portions 13 extending along the longitudinal direction L are formed on the upper surface 11a (mounting surface) of the plate body 11. A plurality of lower rib portions 14 extending along the longitudinal direction L are formed on the lower surface 11b (supported surface) of the plate body 11. In this embodiment, the plurality of upper rib portions 13 and the plurality of lower rib portions 14 are provided at positions corresponding to each other in the width direction W. By providing such a plurality of upper rib portions 13 and lower rib portions 14, it is possible to increase the rigidity in the longitudinal direction L while facilitating the bending deformation along the support portion 61 of the elongated body support 6.

[0046] A through hole 16 is formed in the center of the plate body 11, penetrating vertically. The through hole 16 is formed along the longitudinal direction L. As shown in FIG. 4, the through hole 16 is formed at a position overlapping an elastic retaining piece 20 provided on the lower surface 11b side of the plate body 11 in a plan view. The through hole 16 of this embodiment has a narrow portion 16A having a width corresponding to the width of the elastic retaining piece 20, and a wide portion 16B wider than the narrow portion 16A. The wide portion 16B is formed at a position corresponding to a thin portion 22B of the elastic retaining piece 20 in the longitudinal direction L, which will be described later. In addition, the wide portion 16B is formed in a trapezoidal shape in a plan view in this embodiment.

[0047] The support plate 10 of this embodiment has a pair of extension portions 12 extending from the plate body 11 to both sides in the width direction W. The extension portions 12 are formed in a flat trapezoidal shape in a plan view. The side edges 12a of the extension portions 12 have a portion parallel to the longitudinal direction L at the center of the longitudinal direction L and portions on both sides thereof that are inclined with respect to the longitudinal direction L. A pair of slits 41 extending from the side edges 12a toward the plate body 11 side is formed in each of the extension portions 12 on both sides in the width direction W.

[0048] The support plate 10 is divided into a central region 18 and a pair of outer regions 19 on both sides thereof by a pair of slits 41 formed on both sides in the width direction W. The central region 18 is a region between the pair of slits 41 in the longitudinal direction L. The outer regions 19 are regions outside the central region 18 (one of the pair of slits 41) in the longitudinal direction L. The pair of outer regions 19 may have the same length in the longitudinal direction L or may have different lengths. The through hole 16 is formed from one outer region 19 across the central region 18 to the other outer region 19. In this embodiment, the wide portion 16B of the through hole 16 is formed only in one outer region 19.

[0049] 3, the extension 12 in one outer region 19 is provided with a protrusion 45 that protrudes from the support plate 10 toward the lower surface 11b side, adjacent to the corresponding slit 41 in the longitudinal direction L. In this embodiment, the protrusion 45 is formed as a flat protrusion. The protrusion 45 is provided at a position adjacent to the slit 41 in the longitudinal direction L and overlaps the side edge 12a in the width direction W.

[0050] The elastic retaining piece 20 is made of an elastic body and is provided in a cantilever state on the lower surface 11b of the support plate 10 (plate body 11). The elastic retaining piece 20 is arranged in the center of the support plate 10 (from one outer portion 19, over the center portion 18, to the other outer portion 19) along the longitudinal direction L. The length of the elastic retaining piece 20 along the longitudinal direction L is set to be longer than the support width of the support portion 61 of the elongated body support 6. Therefore, when attached to the support portion 61, the elastic retaining piece 20 is arranged so as to extend on both sides of the longitudinal direction L of the elongated body 8 relative to the support portion 61.

[0051] The elastic retaining piece 20 holds the support portion 61 of the elongated body support 6 from the underside. The elastic retaining piece 20 of this embodiment has a base 21 formed integrally with the support plate 10, and a retaining piece portion 22 formed integrally with the base 21 and consisting of a piece extending in the longitudinal direction L. The elastic retaining piece 20 is configured as an elastic arm with the base 21 as a root portion and the tip portion of the retaining piece portion 22 opposite the base 21 as an open end. The elastic retaining piece 20 is capable of bending and deforming with the base 21 as a fixed end, and the retaining piece portion 22 is capable of bending and deforming in both the width direction W and the up-down direction (thickness direction).

[0052] As shown in FIG. 5, the holding piece 22 has, from the base 21 side toward the tip side, a parallel extending portion 22A, a thin portion 22B, an inclined extending portion 22C, and a tip inclined portion 22D. The parallel extending portion 22A extends from the lower end of the base 21 in parallel to the support plate 10 (plate body 11). The thin portion 22B is formed to be thinner than the parallel extending portion 22A and extends continuously from the parallel extending portion 22A. The thin portion 22B also extends in parallel to the support plate 10 (plate body 11). The inclined extending portion 22C extends from the thin portion 22B at an incline so as to gradually approach the support plate 10 side. In this embodiment, a holding space R is formed as a space surrounded by the support plate 10, the base 21, the parallel extending portion 22A, the thin portion 22B, and the inclined extending portion 22C. In this holding space R, the supporting portion 61 of the elongated body supporting tool 6 is held.

[0053] The inclined tip portion 22D extends from the inclined extension portion 22C at an angle so as to gradually move away from the support plate 10. The surface of the inclined tip portion 22D on the support plate 10 side serves as an insertion guide surface 22e that guides the support portion 61 so that it fits smoothly into the holding space R when the auxiliary support member 1 is attached to the elongated body support tool 6.

[0054] The elastic retaining piece 20 has a thinner thin portion 22B and a tip inclined portion 22D at the tip side, compared to the thickness of the base portion 21 and the parallel extending portion 22A at the base end side. In particular, by making the thickness of the thin portion 22B relatively thin, the tip side of the elastic retaining piece 20 can be easily bent and deformed. Also, the elastic retaining piece 20 is bent so that the inclined extending portion 22C and the tip inclined portion 22D at the tip are located on the support plate 10 side. In this way, by bending the tip side of the elastic retaining piece 20, the distance by which the elastic retaining piece 20 is bent can be shortened.

[0055] 2, a locking portion 30 for locking the tip side of the elastic retaining piece 20 is provided on the upper surface 11a of the support plate 10 (plate body 11), which is the side opposite to the side on which the elastic retaining piece 20 is provided. In this embodiment, the locking portion 30 is formed by utilizing a part of the multiple upper rib portions 13 formed on the upper surface 11a of the plate body 11. In this embodiment, the upper rib portions 13 correspond to the "rib portions."

[0056] Furthermore, in this embodiment, the side surface of the upper rib portion 13 adjacent to the through hole 16 in the width direction W at the tip side of the elastic retaining piece 20 on the opposite side to the through hole 16 is an inclined side surface 13a inclined with respect to the longitudinal direction L (see FIG. 4). This inclined side surface 13a is provided adjacent to the wide portion 16B of the through hole 16 in the longitudinal direction L. The inclined side surface 13a is slightly inclined so as to gradually move outward in the width direction W toward the tip side of the elastic retaining piece 20. The tip side of the elastic retaining piece 20 is engaged with the inclined side surface 13a and the upper surface 11a of the plate body 11 continuing from the inclined side surface 13a. In this embodiment, the inclined side surface 13a formed on a part of the upper rib portion 13 (including the part of the upper surface 11a of the plate body 11 continuing from the inclined side surface 13a) also serves as the engaging portion 30.

[0057] As described above, the elastic retaining piece 20 is provided on the lower surface 11b of the support plate 10 (plate body 11), and the through hole 16 is formed at a position overlapping with the elastic retaining piece 20 in a plan view of the plate body 11. Therefore, the elastic retaining piece 20 can be deformed flexibly in the vertical direction, and its tip side can protrude through the through hole 16 toward the upper surface 11a of the support plate 10 (plate body 11). The through hole 16 includes a wide portion 16B, and this wide portion 16B is provided adjacent to the inclined side surface 13a of a part of the upper rib portion 13 that also serves as the locking portion 30 in the longitudinal direction L. Therefore, the elastic retaining piece 20 can be deformed flexibly in the width direction W as well, and its tip side can be locked to the locking portion 30 (the inclined side surface 13a + the upper surface 11a).

[0058] In fact, when the auxiliary support member 1 is attached to the support portion 61 of the elongate body support 6, as shown in Figs. 6 to 8, the elastic holding piece 20 has its tip side (the inclined extending portion 22C and the tip inclined portion 22D) passing through the through hole 16 and locked to the locking portion 30 on the upper surface 11a side of the support plate 10. Meanwhile, on the lower surface 11b side of the support plate 10 (plate body 11), the elastic holding piece 20 has its base end side (the parallel extending portion 22A) sandwiching the support portion 61 between itself and the lower surface 11b of the plate body 11. At this time, the elastic holding piece 20 is locked to the locking portion 30 in an elastically deformed state, so that the pressing force of the elastic holding piece 20 against the support portion 61 can be increased, and the sliding resistance can be increased to make it difficult for positional deviation (here, positional deviation in the width direction W, in particular) to occur.

[0059] The auxiliary support member 1 of this embodiment further includes an engagement portion 40 that can engage with the support portion 61 from the longitudinal direction L when attached to the support portion 61 of the elongated body support 6. The engagement portions 40 are provided on both sides in the width direction W of the support plate 10 so as to be able to engage with the support portion 61 from both sides in the longitudinal direction L. By providing such engagement portions 40 and engaging the engagement portions 40 with the support portion 61 from both sides in the longitudinal direction L on both sides in the width direction W, the auxiliary support member 1 can be positioned in the longitudinal direction L relative to the elongated body support 6.

[0060] As described above, a pair of slits 41 extending from the side edges 12a toward the plate body 11 are formed in the extensions 12 on both sides in the width direction W of the support plate 10 (see Figs. 2 to 4). The pair of slits 41 have portions extending at least along the width direction W at intervals corresponding to the length of the longitudinal direction L of the support portion 61 of the elongated body support 6. In this embodiment, one of the pair of slits 41 (the one located on the base end side of the elastic retaining piece 20 in the longitudinal direction L) is a linear slit 41A extending straight along the width direction W. The other of the pair of slits 41 (the one located on the tip end side of the elastic retaining piece 20 in the longitudinal direction L) is a folded line slit 41B having a parallel portion 41c parallel to the linear slit 41A and an oblique portion 41d intersecting the parallel portion 41c.

[0061] In this embodiment, the distance in the longitudinal direction L between the linear slits 41A and the parallel portions 41c of the folded slits 41B corresponds to the length in the longitudinal direction L of the support portion 61. The engagement portion 40 is formed by an inner edge 19a of an outer portion 19 located outside the pair of slits 41 in the support plate 10 (plate body 11) in the longitudinal direction L.

[0062] To elaborate on this point, when the auxiliary support member 1 is attached to the support part 61 of the elongate body support 6, the central part 18 between the pair of slits 41 curves to follow the curved shape of the support part 61 (see Figs. 6 and 7). The pair of outer parts 19 on both sides of the central part 18 in the longitudinal direction L curve to some extent to follow the central part 18, but the degree of curvature is kept small. In other words, when attached to the support part 61, the curvature of the pair of outer parts 19 is smaller than the curvature of the central part 18. As a result, the outer parts 19 are arranged to intersect with the support part 61 when viewed in the longitudinal direction L, and the inner edge 19a of the outer parts 19 engages with the support part 61 from the longitudinal direction L.

[0063] In this embodiment, one of the pair of slits 41 is a folded line slit 41B, so that one outer portion 19 has a protruding piece 42 that protrudes toward the central portion 18 along the side edge 12a of the extension portion 12. The distance between the pair of slits 41 at the position of the side edge 12a of the support plate 10 (extension portion 12) (in this example, the distance between the linear slit 41A and the oblique portion 41d of the folded line slit 41B) is shorter than the length of the longitudinal direction L of the support portion 61. The protruding piece 42 functions as a retainer for the support auxiliary member 1 from the support portion 61. For example, after the support auxiliary member 1 is attached to the support portion 61 of the long body support 6, the attached state can be appropriately maintained even before the elastic retaining piece 20 is engaged with the engagement portion 30 (the inclined side surface 13a + the upper surface 11a).

[0064] The auxiliary support member 1 can be attached to the elongated body support 6 as follows. First, as shown in FIG. 9, the auxiliary support member 1 is inserted into the support portion 61 of the elongated body support 6 along the longitudinal direction L. At this time, the support plate 10 is arranged so as to pass above the support portion 61, and the auxiliary support member 1 is slid in the longitudinal direction L with the tip inclined portion 22D, which is the open end of the holding piece portion 22 of the elastic holding piece 20, at the front and inserted. At this time, the tip inclined portion 22D is inclined so as to be further away from the support plate 10 at the tip side, so that the support portion 61 can be smoothly accommodated in the holding space R with the sliding movement. The auxiliary support member 1 is slid until the base portion 21 of the elastic holding piece 20 abuts against the support portion 61 in the longitudinal direction L.

[0065] At this time, the outer region 19 on the front side in the insertion direction (the tip side of the elastic retaining piece 20) is inserted beyond the support part 61 of the elongated body support tool 6 and is not supported from the outside by the support part 61, so that the degree of curvature becomes smaller than that of the central region 18. Accordingly, the overhang piece 42 provided on the outer region 19 is positioned outside the support part 61.

[0066] In this state, as shown in FIG. 10, the auxiliary support member 1 is slid in the opposite direction along the longitudinal direction L. This sliding movement is performed until the inner edge 19a of the outer portion 19 on the front side in the insertion direction abuts against the support portion 61 in the longitudinal direction L. This operation causes the protruding piece 42 provided on the outer portion 19 to be caught on the support portion 61 from the outside. In addition, the outer portion 19 on the rear side in the insertion direction (the base end side of the elastic retaining piece 20) is also in a position that does not engage with the support portion 61, and the degree of curvature is smaller than that of the central portion 18. Accordingly, the inner edge 19a of the outer portion 19 and the protrusion portion 45 provided thereon are engaged with the support portion 61 in the longitudinal direction L. In this way, the auxiliary support member 1 can be positioned relative to the elongated body support 6 in the longitudinal direction L. Therefore, the auxiliary support member 1 can be appropriately temporarily fixed to the elongated body support 6 at an appropriate position in the longitudinal direction L.

[0067] Finally, after adjusting the circumferential position of the auxiliary support member 1 relative to the elongated body support 6, as shown in FIG. 11, the tip side of the elastic holding piece 20 is locked to the locking portion 30 (inclined side surface 13a+upper surface 11a) (see FIG. 6 and FIG. 7 for the locking portion 30). The elastic holding piece 20 is elastically deformed, and its tip side is protruded through the through hole 16 toward the upper surface 11a of the support plate 10 (plate body 11), and is locked to the locking portion 30 on the upper surface 11a side. This allows the support plate 10 and the elastic holding piece 20 to embrace the support portion 61 of the elongated body support 6, and the auxiliary support member 1 can be appropriately held relative to the elongated body support 6. In addition, since the elastic holding piece 20 holds the support portion 61 between its base end side and the lower surface 11b of the plate body 11, the sliding resistance is increased and the position is less likely to be displaced in the circumferential direction.

[0068] In this way, the auxiliary support member 1 of this embodiment can be appropriately held in the appropriate position in the longitudinal direction L relative to the elongated body support 6, and is also less likely to shift in the circumferential direction. Therefore, for example, when subsequently disposing the elongated body 8, when inserting the elongated body 8 into the elongated body support 6, the auxiliary support member 1 can reliably support the elongated body 8 from below without shifting in the longitudinal direction L or the circumferential direction. Since this is achieved solely by the structure of the auxiliary support member 1, without relying on the structure of the elongated body support 6, it can also be suitably applied to a general-purpose elongated body support 6 in which no hole is formed in the support portion 61.

[0069] Second Embodiment A second embodiment of the auxiliary support member and long body support unit will be described with reference to the drawings. The auxiliary support member 1 of this embodiment differs from the first embodiment in the number and positions of the elastic retaining pieces 20, etc. In addition to the specific shape of the auxiliary support member 1, the long body support unit 100 differs from the first embodiment in the specific shape of the long body support tool 6. Below, the auxiliary support member 1 and long body support unit 100 of this embodiment will be described, focusing mainly on the differences from the first embodiment. Note that points that are not specifically mentioned are the same as those in the first embodiment, and the same reference numerals will be used to omit detailed explanations.

[0070] As shown in FIG. 12, the auxiliary support member 1 of this embodiment includes a plurality of elastic retaining pieces 20 (two in this example). The elastic retaining pieces 20 are arranged parallel to each other at a predetermined interval in the width direction W. Correspondingly, the auxiliary support member 1 includes a plurality of through holes 16 (two in this example, the same number as the elastic retaining pieces 20) and locking portions 30 (inclined side surface 13a+upper surface 11a). The locking portions 30 are provided adjacent to the corresponding through holes 16 in the width direction W. The locking portions 30 are provided on the center side of the corresponding through holes 16 in the width direction W. In this embodiment, the two elastic retaining pieces 20 are flexibly deformed in the width direction W so that their respective tip portions approach each other, and are locked to the corresponding locking portions 30.

[0071] 13, the long body support tool 6 provided in the long body support unit 100 of this embodiment has an annular support part 61. The long body support tool 6 also has a box-shaped attachment part (not shown) on the upper part of the annular support part 61. This long body support tool 6 does not have a lid part.

[0072] The auxiliary support member 1 of this embodiment can also reliably support the elongated body 8 from below without being displaced in the longitudinal direction L and in the circumferential direction.

[0073] Other embodiments (1) In each of the above embodiments, a configuration has been described as an example in which the locking portion 30 is provided adjacent to the tip end portion of the elastic retaining piece 20 in the through hole 16 in the width direction W. However, the present invention is not limited to such a configuration, and for example, the locking portion 30 may be provided slightly spaced apart in the width direction W from the tip end portion of the elastic retaining piece 20 in the through hole 16.

[0074] (2) In each of the above embodiments, the through hole 16 has a narrow portion 16A and a wider portion 16B. However, the present invention is not limited to such a configuration, and the through hole 16 may be formed to have a uniform width.

[0075] (3) In each of the above embodiments, a configuration in which a plurality of upper rib portions 13 are formed on the upper surface 11a of the plate body 11 has been described as an example. However, the present invention is not limited to such a configuration, and the plate body 11 may not have the upper rib portion 13, for example, as shown in FIG. 14. In this case, a dedicated locking portion 30 may be provided on the upper surface 11a of the plate body 11. In the illustrated example, the locking portion 30 consisting of a locking protrusion 31 is provided adjacent to a portion of the through hole 16 on the tip side of the elastic retaining piece 20 in the width direction W.

[0076] (4) In each of the above embodiments, a configuration has been described as an example in which a plurality of upper rib portions 13 and a plurality of lower rib portions 14 are provided at positions corresponding to each other in the width direction W. However, the present invention is not limited to such a configuration, and the upper rib portions 13 and the lower rib portions 14 may be provided alternately in the width direction W.

[0077] (5) In the above-mentioned embodiments, the holding piece portion 22 constituting the elastic holding piece 20 has a parallel extending portion 22A, a thin portion 22B, an inclined extending portion 22C, and a tip inclined portion 22D. However, the present invention is not limited to such a configuration. For example, the holding piece portion 22 may be formed to have only the parallel extending portion 22A, the inclined extending portion 22C, and the tip inclined portion 22D without having the thin portion 22B. In this case, as shown in FIG. 15, the holding piece portion 22 may be integrally provided with a hook portion 22E for hooking onto the support portion 61 of the elongated body support 6. Also, as shown in FIG. 16, the parallel extending portion 22A of the holding piece portion 22 may be formed so that its thickness gradually decreases toward the tip side. Also, as shown in FIG. 17, a protrusion 24 protruding toward the support plate 10 side may be integrally formed on the elastic holding piece 20 (holding piece portion 22). In this case, as shown in Fig. 18, for example, a convex portion 24 protruding toward the support plate 10 may be integrally formed on the elastic retaining piece 20 (retaining piece portion 22), and a convex portion 15 protruding toward the elastic retaining piece 20 may be integrally formed on the support plate 10 (plate body 11). In this case, the convex portion 24 of the elastic retaining piece 20 and the convex portion 15 of the support plate 10 may be provided at the same position in the width direction W, or at different positions. The shape of the convex portion 24 and the convex portion 15 may be various shapes, such as a hemispherical shape or a conical shape. In addition to these, the specific configuration of the elastic retaining piece 20 may be changed as appropriate.

[0078] (6) In each of the above embodiments, an example has been described in which one or two elastic holding pieces 20 are provided. However, the present invention is not limited to such a configuration, and the number of elastic holding pieces 20 may be three or more.

[0079] (7) In each of the above embodiments, a configuration has been described in which the auxiliary support member 1 has an engaging portion 40 that can engage with the support portion 61 of the elongate body support 6 from the longitudinal direction L. However, the present invention is not limited to such a configuration, and for example, as shown in Fig. 14, the auxiliary support member 1 does not need to have an engaging portion 40. In this case, as in the illustrated example, the support plate 10 may not have a pair of extension portions 12 on both sides in the width direction W, and may be composed of only a plate body 11 that is rectangular in plan view.

[0080] (8) In each of the above embodiments, a configuration has been described as an example in which the auxiliary support member 1 has the engagement portion 40 on both sides in the width direction W. However, the present invention is not limited to such a configuration, and the auxiliary support member 1 may have an engagement portion 40 on only one side in the width direction W.

[0081] (9) In each of the above embodiments, the pair of slits 41 constituting the engagement portion 40 has a linear slit 41A and a folded line slit 41B (parallel portion 41c+diagonal portion 41d) as an example. However, the present invention is not limited to such a configuration, and the engagement portion 40 may be constituted by a pair of linear slits 41A as shown in FIG. 19. In this case, a through hole 43 may be formed in a portion sandwiched between the pair of linear slits 41A as shown in FIG. 20. In addition, the folded line slit 41B may be formed in a crank shape as shown in FIG. 21, and the engagement portion 40 may be constituted by a pair of folded line slits 41B as shown in FIG. 22. In addition, at least one of the pair of slits 41 may be formed to extend in a diagonal straight line as shown in FIG. 23. Furthermore, instead of providing the pair of slits 41 constituting the engaging portion 40 completely independently, the pair of slits 41 may be formed so as to share a portion on the side edge 12a side thereof (in other words, one slit 41 branches off from the other slit), as shown in Figures 24 and 25. In addition to the above, the specific configuration of the pair of slits 41, and therefore the specific configuration of the engaging portion 40, may be changed as appropriate.

[0082] (10) In each of the above embodiments, the protrusion 45 is configured as a flat plate-shaped protrusion. However, the present invention is not limited to such a configuration, and the protrusion 45 may be configured as an L-shaped rib, for example, as shown in Fig. 26. In addition to this, the specific configuration of the protrusion 45 can be changed as appropriate.

[0083] (11) In the auxiliary support member 1 described in each of the above embodiments, the support plate 10 (plate body 11) may be provided with a magnet in the central portion 18. In this way, when the elongated body support tool 6 is made of a magnetic material, the auxiliary support member 1 can be temporarily fixed to the elongated body support tool 6 more appropriately.

[0084] (12) In the auxiliary support member 1 of each of the above embodiments, the auxiliary support member 1 may further include a support piece portion 50 provided on the lower surface 11b of the support plate 10 at the position of the middle part of the elastic retaining piece 20, as shown in Figs. 27 to 29, for example. The support piece portion 50 can be formed so as to protrude from the lower surface 11b of the support plate 10 in, for example, a triangular shape (such as an isosceles triangle or a right-angled triangle). In addition, the support piece portion 50 can be formed at a position offset in the width direction W from the position of the base portion 21 of the elastic retaining piece 20 by the thickness of the elastic retaining piece 20 in the width direction W.

[0085] In this configuration, when the tip side of the elastic retaining piece 20 is engaged with the engaging portion 30 on the upper surface 11a side of the support plate 10 (plate body 11), the elastic retaining piece 20 is supported from the side by the support piece portion 50. The portion of the elastic retaining piece 20 from its base portion 21 to where it abuts against the support piece portion 50 is in a state along the longitudinal direction L (in other words, perpendicular to the support portion 61 of the elongated body support tool 6), so that the attachment of the auxiliary support member 1 to the elongated body support tool 6 can be stabilized. In addition, the tip side of the elastic retaining piece 20 is bent more greatly and a larger tension acts thereon, so that also from this point of view, the attachment of the auxiliary support member 1 can be further stabilized.

[0086] In addition, when such a configuration is adopted, for example, as shown in Figures 30 and 31, a through hole 62 may be provided in the support portion 61 of the long body support 6, and a fitting protrusion 55 that fits into the through hole 62 may be provided on the support plate 10 of the auxiliary support member 1. The fitting protrusion 55 may be provided, for example, on the lower surface 11b of the support plate 10 of the auxiliary support member 1, directly below the elastic retaining piece 20. In this case, for example, a bridging portion 17 that bridges the through hole 16 in the width direction W may be provided at a position within the range of the support portion 61 of the long body support 6 in the longitudinal direction L of the support plate 10, and the fitting protrusion 55 may be formed on the bridging portion 17. The triangular support piece portion 50 can also function as an attachment guide that guides the fitting protrusion 55 to climb over the support portion 61 when the auxiliary support member 1 is attached by sliding it in the longitudinal direction L relative to the support portion 61 of the long body support 6.

[0087] (13) In the auxiliary support member 1 of each of the above embodiments, for example, as shown in FIG. 29, the thin portion 22B of the holding piece portion 22 constituting the elastic holding piece 20 may be provided at a position within the range of the support portion 61 of the elongated body support 6 in the longitudinal direction L. Also, a thick portion 22F formed to be thicker in the vertical direction may be provided on the tip side of the thin portion 22B. By providing such a thick portion 22F, when the tip side of the elastic holding piece 20 is engaged with the engagement portion 30, the support portion 61 of the elongated body support 6 can be firmly sandwiched between the support plate 10 and the thick portion 22F of the holding piece portion 22. Therefore, the attachment of the auxiliary support member 1 to the elongated body support 6 can be stabilized.

[0088] (14) In each of the above embodiments, an example has been described in which the auxiliary support member 1 includes an elastic retaining piece 20 and an engagement portion 30 to which the tip side of the elastic retaining piece 20 is engaged, and the support portion 61 of the elongated body support 6 is embraced by the support plate 10 and the elastic retaining piece 20. However, the present specification is not limited to such a configuration, and also discloses an auxiliary support member 1 that does not include the elastic retaining piece 20 and the engagement portion 30, but includes the support plate 10 and an engagement portion 40 consisting of a pair of slits 41. Such an auxiliary support member 1 has the following configuration.

[0089] A support auxiliary member 1 is interposed between a support part 61 of a long body support 6 that supports a long body 8 in a suspended state and the long body 8, A support plate 10 extending along the longitudinal direction L of the elongated body 8 is provided. The support plate 10 has a pair of slits 41 formed from its side edge 12a so as to have portions (straight-line slits 41A and oblique portions 41d of folded-line slits 41B) extending at least along the width direction W at an interval corresponding to the length of the longitudinal direction L of the support portion 61, At least on one side in the width direction W, an inner edge 19a of a portion (outer portion 19) of the support plate 10 that is located outside the pair of slits 41 in the longitudinal direction L is capable of engaging with the support portion 61 from both sides in the longitudinal direction L.

[0090] According to this configuration, by simply forming a pair of slits 41 extending from the side edges 12a on at least one side of the width direction W of the support plate 10, a structure that can easily engage with the support part 61 from both sides in the longitudinal direction L of the elongated body 8 can be provided. Then, by engaging the inner edge 19a of the part (outer part 19) that is on the outer side in the longitudinal direction L of the pair of slits 41 with the support part 61 from both sides in the longitudinal direction L of the elongated body 8 on at least one side in the width direction W, the auxiliary support member 1 can be positioned in the longitudinal direction L relative to the elongated body support tool 6. Thus, with a simple configuration, the auxiliary support member 1 can be positioned in the longitudinal direction L relative to the elongated body support tool 6.

[0091] (15) The configurations disclosed in the above-mentioned embodiments (including the above-mentioned embodiments and other embodiments; the same applies below) can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. As for other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be appropriately modified within the scope of the present disclosure.
