Description

[Technical field]

[0001] The present invention relates to a fitting. [Background technology]

[0002] For example, mounting fixtures are used to connect long bolts suspended from a structural body such as a slab that constitutes the ceiling of a building to supports that support piping connected to water facilities, air conditioning facilities, etc. An example of such a mounting fixture is disclosed in JP 2022-75177 A (Patent Document 1).

[0003] The mounting device of Patent Document 1 is mainly composed of a metal fitting called a turnbuckle, and is attached to a suspension bolt, which serves as a long bolt, by a flanged nut (flange nut 13) inserted into an insertion hole (insertion hole 10) formed in the upper surface (top 11) of the fitting.

[0004] When adjusting the mounting position of the mounting tool in Patent Document 1 relative to the long bolt, the position of the flanged nut relative to the long bolt is adjusted. However, because the stroke of the flanged nut moved by the rotation operation is very small, there is a problem in that adjusting the position is time-consuming. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2022-75177 Summary of the Invention [Problem to be solved by the invention]

[0006] It is desirable to realize a mounting tool that can easily adjust its position relative to a long bolt. [Means for solving the problem]

[0007] The mounting fixture according to the present invention comprises: A mounting tool that is attached to a long bolt, a locking member disposed so as to at least partially surround an outer periphery of the long bolt; The locking member is disposed so as to permit relative movement with respect to the long bolt in one axial direction of the long bolt, and to restrict relative movement in the other axial direction.

[0008] With this configuration, the position of the fastener can be easily adjusted simply by moving it relative to the long bolt in one axial direction of the long bolt. After the fastener is set in the desired position, movement of the fastener relative to the long bolt in the other axial direction is restricted, so that the fastener can be appropriately secured in that position.

[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, a retainer for retaining the locking member, It is preferable that the retainer has an elastic support portion which is displaceable by elastic deformation while supporting the locking member.

[0011] According to this configuration, the locking member can be supported and appropriately held by the elastic support part of the cage. In addition, the position of the locking member relative to the long bolt can be easily changed by displacing the elastic support part. As a result, for example, the state in which the relative movement of the mounting fixture toward the other axial direction of the long bolt is restricted can be temporarily released by displacing the elastic support part. This makes it even easier to adjust the position of the mounting fixture.

[0012] In one embodiment, the retainer has a pair of side walls which cover sides of the elastic support portion and the locking member, It is preferable that the side wall portion is formed with an opening for accessing the locking member.

[0013] With this configuration, the locking member is stably held by the pair of side wall portions, while the position of the elastic support portion and the locking member supported by it can be easily changed by an operator operating through the opening.

[0014] In one embodiment, It is preferable that the elastic support portion is disposed at an incline such that the base end side is positioned downward and the tip side is positioned upward.

[0015] With this configuration, the position of the mounting fixture can be easily adjusted, for example by moving it upward relative to a long bolt arranged in the vertical direction, and the mounting fixture can be appropriately secured in that position by restricting its movement downward relative to the long bolt.

[0016] In one embodiment, It is preferable that the locking member has a plurality of locking pieces arranged around the long bolt and locking to the long bolt at their tip edges.

[0017] With this configuration, the function of the locking member, which allows relative movement in one axial direction with respect to the long bolt while restricting relative movement in the other direction, can be effectively achieved by a relatively simple configuration including multiple locking pieces.

[0018] In one embodiment, It is preferable that the tip edge of the locking piece is disposed inclined with respect to the axial direction so as to follow the helix of the thread of the long bolt.

[0019] This configuration allows the tip edge of the locking piece to be more securely locked onto the thread of the long bolt. Also, the entire mounting tool including the multiple locking pieces can be rotated around the axis of the long bolt, allowing the position of the mounting tool in the axial direction to be adjusted.

[0020] In one embodiment, It is preferable that the tip edge of the locking piece is curved so as to cover at least one side of the long bolt while being locked to the long bolt.

[0021] With this configuration, even if an external force having a horizontal component acts on the fastener attached to the long bolt, the locked state between the long bolt and the locking piece can be maintained favorably.

[0022] In one embodiment, A mounting member is provided that is attached to the long bolt, It is preferable that the mounting member is provided with a stopper that restricts relative movement of the long bolt toward one axial direction within a predetermined range.

[0023] This configuration makes it possible to prevent the fastener from being inserted too far axially into the long bolt.

[0024] In one embodiment, The long bolt is a suspension bolt suspended from a structure, It is preferable that the suspension bolt is connected to a support for supporting the piping.

[0025] With this configuration, the vertical position of the fixture relative to the hanging bolt can be easily adjusted, and the vertical position of the support that supports the piping can also be easily adjusted. Therefore, for example, when installing piping, a drainage gradient can be easily set if necessary.

[0026] 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]

[Figure 9] 1 is a side view of another embodiment of the mounting fixture; [Figure 10] FIG. 13 is a perspective view of another embodiment of the mounting fixture; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] [First embodiment] A first embodiment of a fixture will be described with reference to the drawings. A fixture 1 of this embodiment is attached to a long bolt B. As shown in FIG. 1, this embodiment will be described with an example of a fixture 1 constituting a part of a pipe support 100 for supporting a pipe P in a suspended state from a structure S. In this example, the long bolt B is a suspension bolt supported in a suspended state from the structure S, and the fixture 1 is attached to the suspension bolt and is connected to a support 5 that supports the pipe P, connecting the suspension bolt and the support 5.

[0029] The structure S is, for example, a slab constituting a ceiling. The long bolts B are arranged along the installation direction of the pipe P. A plurality of long bolts B are installed at a predetermined interval at a plurality of locations along the installation direction of the pipe P, and the pipe P is supported in a horizontal position by the pipe supports 100 attached to each of the long bolts B, so that the pipe P is suspended over the entire installation direction.

[0030] As the long bolt B, a fully threaded bolt having threads cut along its entire length may be used, or a double-threaded bolt having threads cut only on both ends may be used.

[0031] As shown in FIG. 1, a piping support 100 includes a mounting fixture 1, a support 5 for supporting a piping P, and a fastening member 6 for connecting the mounting fixture 1 and the support 5.

[0032] The support 5 is not particularly limited as long as it has a structure capable of supporting the pipe P. The support 5 of this embodiment is composed of a pair of divided bodies 50. Each of the pair of divided bodies 50 has a flat plate portion 51 having an insertion hole formed therein, and a curved portion 52 that curves along the outer surface of the pipe P. The pair of divided bodies 50 are connected to each other so as to be able to open and close freely by a hinge portion 55 provided at an end of each curved portion 52 opposite to the flat plate portion 51.

[0033] The support 5 is formed integrally by, for example, pressing using a strip-shaped steel plate.

[0034] The fastening member 6 has a fastening bolt 61 and a nut 62 that screws into the fastening bolt 61. The fastening bolt 61 connects the mounting fixture 1 and the support fixture 5 by fastening the nut 62 with its shaft portion inserted into an insertion hole of the flat plate portion 51 and an insertion hole 12a of a connecting plate 12 of the mounting fixture 1, which will be described later.

[0035] 2 and 3, the mounting tool 1 of this embodiment includes a mounting member 10, a retainer 20, a locking member 30, and a connecting member 40. The mounting member 10, the retainer 20, the locking member 30, and the connecting member 40 are configured as separate members independent of one another, and are combined as a whole to form a unit.

[0036] The mounting member 10 has a mounting plate 11 and a pair of connecting plates 12 extending downward from the mounting plate 11. The mounting plate 11 is formed in a flat plate shape. An insertion hole 11a is formed through the mounting plate 11. A long bolt B is inserted into the insertion hole 11a. In this embodiment, a connecting column 42 of a connecting member 40 is also inserted into the insertion hole 11a.

[0037] The pair of connecting plates 12 are provided so as to extend downward from the mounting plate 11. The pair of connecting plates 12 are each bent at two points to form a gentle crank shape so that the gap between the lower end side (opposite the mounting plate 11) is narrower than the upper end side (the mounting plate 11 side). An insertion hole 12a is formed through the lower end of the connecting plate 12. A shaft portion of a fastening bolt 61 constituting the fastening member 6 is inserted through this insertion hole 12a. In addition, a notch hole 12b is formed through the upper end of the connecting plate 12 in the portion where the opposing gap between the connecting plates 12 is narrowed. This notch hole 12b is a notch for avoiding interference with the lower end of the long bolt B. In addition, the inner edge of the notch hole 12b engages with the thread on the outer surface of the long bolt B when the fastening member 6 is fastened, and the notch hole 12b also plays a role in permanently fixing the mounting tool 1 to the long bolt B.

[0038] The mounting member 10 is formed integrally from a strip-shaped steel plate, for example, by press working, etc. As an example of such a mounting member 10, a turnbuckle can be used.

[0039] The retainer 20 is a member for retaining the locking member 30 relative to the mounting member 10. As shown in Fig. 4, the retainer 20 is formed in a box shape as a whole. The retainer 20 has an upper wall portion 21, a vertical wall portion 22, an elastic support portion 23, and a pair of side wall portions 24. These are integrally formed by, for example, pressing using a thin metal plate that is thinner than the steel plate that constitutes the mounting member 10.

[0040] The upper wall portion 21 is formed in a flat plate shape. The upper wall portion 21 is formed in a rectangular shape. An insertion hole 21a is formed through the upper wall portion 21. The upper wall portion 21 is attached in a state where it is in contact with the lower surface of the mounting plate 11 of the mounting member 10. When the upper wall portion 21 and the mounting plate 11 are in contact with each other, the insertion hole 21a and the insertion hole 11a of the mounting plate 11 communicate vertically. A long bolt B is inserted into the insertion hole 21a, and the connecting column body 42 of the connecting member 40 is also inserted into the insertion hole 21a.

[0041] The vertical wall portion 22 is provided so as to extend downward from one side of the rectangular upper wall portion 21. The vertical wall portion 22 is formed in a flat plate shape. The vertical wall portion 22 is formed in a rectangular shape.

[0042] The elastic support portion 23 is provided so as to extend obliquely upward from the lower end portion (the end portion opposite the upper wall portion 21) of the vertical wall portion 22. The elastic support portion 23 is formed in a flat plate shape. A cutout hole 23a is formed through the center portion of the elastic support portion 23. This cutout hole 23a is formed continuously from the elastic support portion 23 to the lower end side of the vertical wall portion 22. The elastic support portion 23 is formed in a U-shape. As shown in FIG. 3, the elastic support portion 23 supports the locking member 30 from below.

[0043] The elastic support 23 is displaceable by elastic deformation while supporting the locking member 30. More specifically, while supporting the locking member 30, the elastic support 23 is displaceable by applying an external force so that the tip end of the upper end bends downward around the base end of the lower end as an axis (see FIG. 5). The elastic support 23 is changeable in posture to a first inclination posture in which the base end is located downward and the tip end is located upward at a first angle α, and a second inclination posture in which the base end is located downward and the tip end is located upward at a second angle β. Here, the second angle β is smaller than the first angle α. As an example, the first angle α can be about 30° to 45°, and the second angle β can be about 10° to 25°.

[0044] The pair of side wall portions 24 are provided so as to extend laterally from a pair of side edges (edges other than the upper edge connected to the upper wall portion 21 and the lower edge connected to the elastic support portion 23) of the rectangular vertical wall portion 22. The side wall portion 24 is formed in a flat plate shape. The side wall portion 24 is formed in a rectangular shape. The pair of side wall portions 24 are arranged so as to cover the sides of the elastic support portion 23 and the locking member 30 supported thereby. In this embodiment, the pair of side wall portions 24 are arranged so as to be perpendicular to the pair of connecting plates 12 of the mounting member 10.

[0045] An opening 25 is formed through the pair of side walls 24 near the center thereof. The opening 25 is formed in a pentagonal or home base shape having an upper oblique side parallel to the elastic support portion 23 in the first inclined position and a lower horizontal side parallel to the upper wall portion 21. By providing such an opening 25, the locking member 30 supported by the elastic support portion 23 in the space laterally covered by the pair of side walls 24 can be accessed from the outside. In other words, the opening 25 is an opening for operating the locking member 30.

[0046] In this embodiment, the locking member 30 is held between the pair of side walls 24 with its outer edge entering the opening 25 or slightly protruding from the opening 25. Therefore, the opening 25 also serves to restrict the posture of the locking member 30 and the elastic support portion 23 that supports it within a certain range. That is, the opening 25 restricts the locking member 30 and the elastic support portion 23 to a posture inclined at an angle equal to or greater than the second angle β and equal to or less than the first angle α (a first inclined posture, a second inclined posture, or a posture between these).

[0047] The locking member 30 is disposed surrounding the outer periphery of the long bolt B so as to be able to lock onto the long bolt B. In this embodiment, a washer 31 is used as the locking member 30, and more specifically, a set of two overlapping washers 31 is used. A central hole 31a is formed through the center of the washer 31. By inserting the long bolt B into this central hole 31a, the washer 31 as the locking member 30 is disposed surrounding the entire outer periphery of the long bolt B.

[0048] 2 and 3, the locking member 30 is supported from below by the elastic support portion 23 of the retainer 20. As described above, the elastic support portion 23 is in the first inclined position when no external force is applied. By being supported from below by the elastic support portion 23 in this first inclined position, the locking member 30 is arranged at a first angle α with respect to the long bolt B arranged along the vertical direction.

[0049] An inner edge 31e around the central hole 31a of the locking member 30 in the first inclined position locks into a thread formed on the outer surface of the long bolt B. At this time, the locking member 30 in the first inclined position functions to allow relative movement with respect to the long bolt B toward one side (upper side in FIG. 3) in the axial direction L of the long bolt B, and to restrict relative movement toward the other side (lower side in FIG. 3). Therefore, the locking member 30 can be easily attached to the long bolt B without involving any tightening operations of bolts and nuts, for example, and can be firmly fixed in a predetermined position on the long bolt B.

[0050] Furthermore, in this embodiment, the locking member 30 is composed of a washer 31 having a certain thickness or more, and is used in pairs stacked together, so that sufficient strength can be ensured even without using bolts or nuts.

[0051] The connecting member 40 is a member for connecting the retainer 20 to the mounting member 10. As shown in Fig. 3, the connecting member 40 has a main body 41, a connecting column 42, and a locking claw 43. These are integrally formed using a resin material such as polyethylene, polypropylene, polystyrene, or polyvinyl chloride.

[0052] The main body 41 is formed in a cylindrical shape that is slightly larger than the long bolt B. A through hole 41a that penetrates vertically is formed in the center of the main body 41. The long bolt B is inserted into this through hole 41a. The connecting column 42 extends downward from the lower end of the main body 41. Multiple connecting columns 42 (three in this example) are provided, and the multiple connecting columns 42 are distributed and arranged in the circumferential direction. A locking claw 43 is provided at the tip (lower end) of the connecting column 42 facing outward.

[0053] The connecting member 40 is attached to the mounting member 10 from above. At this time, with the connecting column 42 inserted through the insertion hole 11a of the mounting plate 11 of the mounting member 10 and the insertion hole 21a of the upper wall portion 21 of the retainer 20, the locking claw 43 locks onto the underside of the upper wall portion 21. As a result, with the mounting plate 11 and the upper wall portion 21 sandwiched between the main body 41 of the connecting member 40 and the locking claw 43, the retainer 20 is connected to the mounting member 10, and the locking member 30 can be held in the first inclined position relative to the mounting member 10.

[0054] As described above, the locking member 30 in the first inclined posture allows only relative movement with respect to the long bolt B toward one side in the axial direction L of the long bolt B, and restricts relative movement toward the other side. For this reason, if the mounting tool 1 is inserted too far into the long bolt B, there is a concern that the mounting position cannot be corrected as is.

[0055] In such a case, in this embodiment, as shown in Fig. 5, the locking member 30 is held through the openings 25 formed in a pair of side walls 24 of the cage 20, and is changed from the first inclined position to the second inclined position. That is, the tip end of the elastic support portion 23 is pressed downward through the locking member 30, and the elastic support portion 23 and the locking member 30 supported thereby are changed from the first inclined position to the second inclined position.

[0056] When the locking member 30 assumes the second inclined position, the inner edge 31e around the central hole 31a of the locking member 30 disengages from the thread on the outer surface of the long bolt B. This temporarily permits relative movement of the long bolt B toward the other side in the axial direction L (the lower side in FIG. 3), which was restricted in the first inclined position. Note that relative movement of the long bolt B toward one side in the axial direction L (the lower side in FIG. 3) continues to be permitted. Thus, with the locking member 30 pressed down to assume the second inclined position, the mounting position of the mounting tool 1 relative to the long bolt B can be readjusted.

[0057] After completing the position adjustment, the pressing operation on the locking member 30 can be simply released. Then, the elastic support portion 23 returns to the first inclined position again due to its elastic restoring force, and the locking member 30 also returns to the first inclined position accordingly. This allows the mounting tool 1 to be attached to the long bolt B at an appropriate position in the vertical direction. Furthermore, the height of the pipe P suspended and supported by the pipe support tool 100 can be easily optimized, and a drainage gradient can be easily and appropriately set when the pipe P includes a drain pipe for an air conditioning facility, for example.

[0058] Thus, in this embodiment, the elastic support portion 23 and the locking member 30 are capable of changing their positions between a first inclined position inclined at a first angle α and a second inclined position inclined at a second angle β smaller than the first angle α. Accordingly, the central hole 31a of the locking member 30 (washer 31) is also variable between the first inclined position inclined at the first angle α and the second inclined position inclined at the second angle β.

[0059] Here, if the inner diameter of the central hole 31a of the locking member 30 (washer 31) is "D", the length of the central hole 31a along the radial direction (direction perpendicular to the axial direction L) of the long bolt B in the first inclined position is "D1", and the length of the central hole 31a in the second inclined position is "D2", the following relationship holds. D1 = D cosα <D2=D·cosβ

[0060] Furthermore, if the distance between the inner edge of the center hole 31a along the radial direction (direction perpendicular to the axial direction L) of the long bolt B in the first inclined posture and the outer surface of the long bolt B is "d1," and the distance between the inner edge of the center hole 31a and the outer surface of the long bolt B in the second inclined posture is "d2," the following relationship holds: d1 <d2

[0061] Second Embodiment A second embodiment of the mounting tool will be described with reference to the drawings. In this embodiment, the specific configuration of the locking member 30 is different from that of the first embodiment. Accordingly, the presence or absence of the retainer 20 is also different from that of the first embodiment. Below, the mounting tool 1 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 of the first embodiment, and the same reference numerals will be used to omit detailed explanations.

[0062] As shown in Fig. 6, the mounting tool 1 of this embodiment includes a mounting member 10, a locking member 30, and a connecting member 40. The mounting tool 1 of this embodiment does not include a retainer 20. The mounting member 10, the locking member 30, and the connecting member 40 are configured as separate members independent of each other. The configurations of the mounting member 10 and the connecting member 40 are similar to those of the first embodiment.

[0063] The locking member 30 of this embodiment is not held by the mounting member 10 by the retainer 20, but is directly connected to and held by the mounting member 10. The locking member 30 of this embodiment is composed of a locking unit 35 in which a portion connected to the mounting member 10 and a portion that locks to the long bolt B are integrated. The locking unit 35 has an upper wall portion 36 and a plurality of locking pieces 37. These are integrally formed by, for example, pressing using a thin metal plate that is thinner than the steel plate that constitutes the mounting member 10. The thin metal plate that constitutes the locking unit 35 may be the same as the thin metal plate that constitutes the retainer 20 in the first embodiment.

[0064] The upper wall portion 36 is formed in a flat plate shape. An insertion hole is formed through the upper wall portion 36. The upper wall portion 36 is attached in a state where it is in contact with the lower surface of the mounting plate 11 of the mounting member 10. With the upper wall portion 36 and the mounting plate 11 in contact with each other, the locking unit 35 is connected to the mounting member 10 by the connecting member 40.

[0065] The multiple locking pieces 37 are distributed in the circumferential direction and extend downward from the upper wall portion 36. Each of the multiple locking pieces 37 has a hanging piece portion 37A that is provided on the upper wall portion 36 and extends in the vertical direction, and an inclined piece portion 37B that extends at an angle from the lower end of the hanging piece portion 37A toward the tip end so as to approach the long bolt B. As a result, the locking unit 35 having the multiple locking pieces 37 is arranged to intermittently surround the outer periphery of the long bolt B so as to be able to lock onto the long bolt B. In this way, the locking member 30 (locking unit 35) does not necessarily have to surround the entire outer periphery of the long bolt B as in the first embodiment, and may be arranged to partially surround the outer periphery of the long bolt B.

[0066] In this embodiment, the multiple locking pieces 37 include two locking pieces 37 (rectangular locking pieces) that are relatively long in length along the axial direction L of the long bolt B, and two locking pieces 37 (short locking pieces) that are relatively short in length along the axial direction L of the long bolt B. These four locking pieces 37 are arranged around the long bolt B with the rectangular locking pieces and the short locking pieces alternately arranged.

[0067] A tip edge 37e of a locking piece 37 (specifically, an inclined piece portion 37B) of a locking unit 35 serving as a locking member 30 locks into a thread formed on the outer surface of a long bolt B. At this time, the inclined piece portion 37B functions to permit relative movement with respect to the long bolt B toward one side (upper side in FIG. 6) in the axial direction L of the long bolt B, and to restrict relative movement toward the other side (lower side in FIG. 6). Therefore, the mounting tool 1 of this embodiment can also be easily attached to the long bolt B, and can be firmly fixed to a predetermined position on the long bolt B.

[0068] Third Embodiment A third embodiment of the mounting tool will be described with reference to the drawings. In this embodiment, the specific configuration of the locking member 30 is different from that of the second embodiment. Below, the mounting tool 1 of this embodiment will be described, focusing mainly on the differences from the second embodiment. Note that points that are not specifically mentioned are the same as those of the second embodiment, and the same reference numerals will be used to omit detailed description thereof.

[0069] 7, the mounting tool 1 of this embodiment includes a mounting member 10, a locking member 30, and a connecting member 40. As in the second embodiment, the locking member 30 is configured with a locking unit 35 in which a portion connected to the mounting member 10 and a portion that locks to the long bolt B are integrated. The locking unit 35 of this embodiment has an upper wall portion 36 and a plurality of locking pieces 37 (three in this example) that are equal in length along the axial direction L of the long bolt B.

[0070] The locking piece 37 of this embodiment has a first inclined piece portion 37C that extends at an incline toward the long bolt B as it moves downward from the upper wall portion 36, and a second inclined piece portion 37D that extends from a lower end of the first inclined piece portion 37C at a steeper incline than the first inclined piece portion 37C. A tip edge 37e of the locking piece 37 (specifically, the second inclined piece portion 37D) of the locking unit 35 serving as the locking member 30 locks with a thread formed on the outer surface of the long bolt B. The linear tip edge 37e of the locking piece 37 (the second inclined piece portion 37D) is disposed at an incline with respect to the axial direction L of the long bolt B so as to follow the helix of the thread of the long bolt B.

[0071] This configuration makes it possible to more reliably engage tip edge 37e of locking piece 37 with the thread of long bolt B. Also, the entire mounting tool 1 including locking unit 35 can be rotated around the axis of long bolt B, thereby making it possible to adjust the position of mounting tool 1 in the axial direction L.

[0072] [Fourth embodiment] A fourth embodiment of the mounting tool will be described with reference to the drawings. In this embodiment, the specific configuration of the locking member 30 is different from that of the third embodiment. The following describes the mounting tool 1 of this embodiment, focusing mainly on the differences from the third embodiment. Note that points that are not specifically mentioned are the same as those of the third embodiment, and the same reference numerals are used to omit detailed descriptions thereof.

[0073] 8, the locking member 30 (locking unit 35) of the mounting tool 1 of this embodiment has a curved tip edge 37e of the locking piece 37 (second inclined piece portion 37D). The tip edges 37e of the multiple locking pieces 37 are each curved in a U-shape so as to cover both sides of the long bolt B while locking to the long bolt B. The locking piece 37 of this embodiment has a locking portion 37x that locks to the long bolt B, and a pair of protruding portions 37y that protrude toward the tip side on both sides of the locking portion 37x.

[0074] Note that Figure 8 shows an example in which the tip edge 37e of the locking portion 37x of the locking piece 37 is arranged perpendicular to the axial direction L of the long bolt B, but as in the third embodiment, the tip edge 37e of the locking portion 37x may be arranged at an angle to the axial direction L of the long bolt B.

[0075] In this embodiment, the tip edge 37e of the locking piece 37 is curved in a U-shape so as to cover both sides of the long bolt B, so that the locking state between the long bolt B and the locking piece 37 can be maintained satisfactorily even if an external force having a horizontal component acts on the mounting fixture 1.

[0076] Other embodiments (1) In the above first embodiment, the elastic support portion 23 and the locking member 30 (washer 31) supported thereon are configured to be displaceable between a first inclined position and a second inclined position. However, the present invention is not limited to such a configuration, and the elastic support portion 23 and the locking member 30 (washer 31) may be displaceable between, for example, a first inclined position and a horizontal position.

[0077] (2) In the above first embodiment, a configuration in which the washer 31 is provided as the locking member 30 has been described as an example. However, the present invention is not limited to such a configuration, and the washer 31 does not necessarily have to be provided. In this case, for example, the elastic support portion 23 of the retainer 20 may be formed to have a central hole similar to that of the washer 31, and the retainer 20 having the elastic support portion 23 may function as the locking member 30.

[0078] (3) In the above first embodiment, a configuration has been described as an example in which the mounting member 10 and the retainer 20 are connected so that the side wall portion 24 and the connecting plate 12 are perpendicular to each other. However, the present invention is not limited to such a configuration, and the mounting member 10 and the retainer 20 may be connected so that the side wall portion 24 and the connecting plate 12 are parallel to each other. In addition to these, the mounting member 10 and the retainer 20 may be connected so that the side wall portion 24 and the connecting plate 12 intersect at any angle.

[0079] (4) In the above first embodiment, a configuration has been described as an example in which the cage 20 has a pair of side wall portions 24. However, the present invention is not limited to such a configuration, and the cage 20 does not necessarily have to have a pair of side wall portions 24.

[0080] (5) In the fourth embodiment, the locking piece 37 has a locking portion 37x and a pair of protruding portions 37y located on both sides thereof. However, the present invention is not limited to such a configuration, and each of the locking pieces 37 may have a locking portion 37x and one protruding portion 37y located on one side, as shown in FIG. 9. Even in such a configuration, the protruding portions 37y of the locking pieces 37 cooperate with each other to maintain a good locking state between the long bolt B and the locking pieces 37. In this way, it is sufficient that the tip edge 37e of the locking piece 37 is curved so as to cover at least one side of the long bolt B while being locked to the long bolt B.

[0081] (6) In the above third and fourth embodiments, a configuration has been described as an example in which the multiple locking pieces 37 are adjacent to each other at approximately the same positions in the axial direction L and lock onto the long bolt B. However, the present invention is not limited to such a configuration, and the multiple locking pieces 37 may be locked onto the long bolt B at different positions in the axial direction L. When such a configuration is adopted, each locking piece 37 can be formed wide, and for example, when the tip edge 37e of the locking piece 37 is formed curved as in the fourth embodiment, it is possible to surround the long bolt B over a wider range. Therefore, the locked state between the long bolt B and the locking pieces 37 can be maintained even better.

[0082] (7) In the above second to fourth embodiments, the locking unit 35 constituting the locking member 30 has three or four locking pieces 37. However, the present invention is not limited to such a configuration, and the number of locking pieces 37 included in the locking unit 35 may be two, or five or more.

[0083] (8) In the second to fourth embodiments described above, the locking piece 37 does not have to extend directly from the upper wall portion 36, but may be provided in the middle of a downward extending piece that extends downward from the upper wall portion 36.

[0084] (9) In each of the above embodiments, a stopper 12C may be provided on the mounting member 10, as shown in Fig. 10, for example. The stopper 12C serves to restrict the relative movement of the long bolt B in one direction in the axial direction L, which is permitted by the locking member 30, within a predetermined range. Providing such a stopper 12C makes it possible to prevent the mounting tool 1 from being inserted too far in the axial direction L into the long bolt B. In the illustrated example, the stopper 12C is formed by cutting out a portion of one of the pair of connecting plates 12 that will become the notch hole 12b when the mounting member 10 is formed.

[0085] (10) In each of the above embodiments, a spacer 12D may be provided on the mounting member 10, as shown in FIG. 10. The spacer 12D plays a role in maintaining a certain distance between the lower ends of the pair of connecting plates 12 when fastening the fastening member 6 to connect the mounting member 10 and the support 5. By providing such a spacer 12D, the flat plate portions on the lower ends of the pair of connecting plates 12 bend with the spacer 12D as a fulcrum when fastening the fastening member 6, thereby improving the tightening force of the fastening member 6 and enabling it to be attached to the long bolt B more firmly. In the illustrated example, the spacer 12D is formed by pressing the lower end of one of the pair of connecting plates 12 when the mounting member 10 is formed.

[0086] (11) In each of the above embodiments, the mounting member 10 is configured as a turn buckle. However, the mounting member 10 is not limited to such a configuration, and the specific configuration of the mounting member 10 may be any configuration.

[0087] (12) In each of the above embodiments, a configuration in which the connecting member 40 is used to connect the mounting member 10 and the retainer 20 has been described as an example. However, the present invention is not limited to such a configuration, and the mounting member 10 and the retainer 20 may be directly connected to each other without using the connecting member 40. In this case, for example, the retainer 20 may be provided with an engagement portion for engaging with the mounting member 10, or the mounting member 10 may be provided with an engagement portion for engaging with the retainer 20.

[0088] (13) In each of the above embodiments, the support 5 is configured as a pair of divided bodies 50 connected so as to be freely opened and closed by the hinge portion 55. However, the present invention is not limited to such a configuration, and for example, the support 5 may be configured so as to be freely opened and closed like a double door by the hinge portions 55 at two locations, or may be configured as a pair of divided bodies 50 that can be engaged and separated. In addition to the above, the specific configuration of the support 5 may be any desired one.

[0089] (14) In each of the above embodiments, an example has been described in which the mounting fixture 1 is applied to a component part of a pipe support 100 for supporting a pipe P in a suspending manner on a structure S. However, the present invention is not limited to such a configuration, and the mounting fixture 1 may be used not only for supporting a pipe P in a suspending manner, but also for other purposes such as preventing other objects from falling. Furthermore, the mounting object is not necessarily limited to a hanging bolt, and the mounting fixture 1 can be used for any type of long bolt B, such as a fully threaded bolt that is hung upward, a fully threaded bolt that is arranged horizontally, or a fully threaded bolt that is arranged diagonally.

[0090] (15) The configurations disclosed in the above-mentioned embodiments (including the above-mentioned first to fourth 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.
