Description

[Technical Field]

[0001] The present invention relates to a fastener for fixing a supported object such as a refrigerant pipe or cable to a long member such as a hanging member, or for fixing a supported object such as a diagonal member made of a fully threaded bolt to a long member such as a fully threaded bolt. [Background technology]

[0002] BACKGROUND ART Patent Document 1 proposes a pipe support mounting member as a fixture for attaching a support band that supports pipes to a hanging member suspended from an architectural structure.

[0003] The mounting member of Patent Document 1 will be explained with reference to Figure 22. Figure 22 shows the mounting member, with the upper part fixed to the structure and the other part hanging downward, as viewed in the axial direction of a hanging bolt (hanging member) a, where (a) shows the state during installation and (b) shows the state during an earthquake.

[0004] As shown in Figure 22, the mounting member (fixture) has a roughly U-shaped mounting body c for assembling a support band b to a hanging bolt a, and in the mounting body c, upper and lower bent portions e and f of a base d are provided with engagement holes g and h that engage with the hanging bolt a, and biasing members i that bias the hanging bolt a are provided in the engagement holes g and h. Note that Figure 22 shows only one side of the upper and lower bent portions e and f and the engagement holes g and h.

[0005] When the mounting member is installed, as shown in Figure 22(a), when the suspension bolt a is engaged in the engagement holes g and h, the biasing member i biases the suspension bolt a, and the inclined portion i1 of the biasing member i and the wedge-shaped tapered portions g1 and h1 in the engagement holes g and h abut against the suspension bolt a, engaging with the threads (groove portion) of the suspension bolt a and fixing it in place through the biasing force.

[0006] On the other hand, when a large external force such as an earthquake applies a load in the direction (indicated by the symbol "F1") that causes support band b to approach suspension bolt a, as shown in Figure 22(b), the biasing member (spring member) i receives a force from suspension bolt a in the opposite direction (indicated by the symbol "F2"), and the biasing member i is pushed back until it hits the support band b side ends (indicated by the symbols "g2, h2") of engagement holes g and h.

[0007] This increases the gap δ toward the openings g3, h3 of the engagement holes g, h. In the event of a large external force such as an earthquake, the mounting member may become disengaged from the suspension bolt (suspending member) a and fall off.

[0008] Patent Document 2 also discloses a pipe support (fixing device) in which a suspending member is inserted into an engagement hole to bias the suspending member, but this too may have the same problems as described above when subjected to a large external force.

[0009] In addition, in order to fix and support equipment to a structure, the long member and the supported part are sometimes made of diagonal members with fully threaded bolts, and even the fasteners that secure the diagonal members together can have the problem of falling off due to a large external force.

[0010] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-223241 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-289360 Summary of the Invention [Problem to be solved by the invention]

[0011] As described above, with conventional fasteners, if a large unintended external force such as an earthquake force is applied after installation, the biasing member may be pushed, causing the attachment position relative to the hanging member to change, or the biasing member may be pushed by the vibration of the supported equipment, causing the fastener to come off the long member or supported object.

[0012] In view of the above circumstances, the present invention aims to provide a fastener that can prevent a long member or a supported object from coming off even when a large external force is applied. [Means for solving the problem]

[0013] The present invention is a fixing device for fixing a supported object to an elongated member, comprising: a support portion for supporting the supported object; a base portion to which the support portion is attached on one side; an attachment body provided on the other side of the base and having an engaging portion whose abutting end abuts and engages with the elongated member introduced into an engaging hole from an opening; and a biasing member that biases the elongated member from one end side to the abutting end side within the engaging hole, wherein the biasing member is formed with an engaging structure that engages with the side portion of the elongated member to prevent the elongated member from coming off the engaging hole.

[0014] In the present invention, it is preferable that when the elongated member in the engagement hole is moved toward the one end by deforming the urging member due to an external force, the elongated member abuts against the one end and is positioned accordingly, and at the same time, when the urging member is deformed, the urging member is deformed to a rear position farther away from the abutting end than the one end.

[0015] In the present invention, it is preferable that the locking structure of the urging member is a convex portion, and when the elongated member in the engagement hole is deformed by an external force and moves toward the one end portion, the gap δ narrowed by the convex portion of the opening is smaller than the outer diameter D of the elongated member.

[0016] In the present invention, the engaging portion protrudes toward the one end near the opening, and a locking portion is formed that makes the distance between the opening smaller than the distance between the one end and the abutting end, and it is preferable that when the elongated member in the engaging hole moves toward the opening due to an external force while being biased by the biasing member, the locking portion restricts the movement of the elongated member.

[0017] In the present invention, it is preferable that the urging member has an introduction end formed continuously with the locking structure for pressing the urging member with the elongated member when the elongated member is introduced into the engagement hole from the opening.

[0018] In the present invention, the introduction end is formed on a slope that moves away from the end opposite the abutment end as it approaches the locking structure, and it is preferable that the locking structure is formed at a position closer to the one end than the terminal end of the introduction end.

[0019] The present invention is a fixing device for fixing a supported object to an elongated member, comprising: a support portion for supporting the supported object; a base portion to which the support portion is attached on one side; an attachment body having an engaging portion protruding from the other side of the base and having an abutting end portion which engages with the elongated member introduced into an engaging hole from an opening; a biasing member which biases the elongated member from one end side to the abutting end side within the engaging hole; and a fall-off prevention member which, separate from the biasing member, has a locking structure formed to lock onto the side portion of the elongated member within the engaging hole and prevents the elongated member from coming off the engaging hole.

[0020] In the present invention, when an external force causes the elongated member in the engagement hole to deform the spring member or anti-fall-out member and move toward one end, it is preferable that the one end abuts against the elongated member to restrict movement.

[0021] In the present invention, it is preferable that the biasing member is an elastic plate member that protrudes obliquely in a direction away from the base portion, and that a locking structure is formed at the tip end portion.

[0022] In the present invention, it is preferable that the locking structure is formed by a notch at the tip of the biasing member.

[0023] In the present invention, the biasing member is an elastic plate material that protrudes obliquely in a direction away from the base, and the biasing member is formed with a recess toward the base side as an engagement structure into which the side portion of the elongated member is fitted to prevent the elongated member from coming off the engagement hole, and it is preferable that the recess is provided with a holding portion that holds the side portion of the elongated member.

[0024] In the present invention, the support portion is preferably a support band. [Effects of the Invention]

[0025] According to the fixing device of the present invention, the biasing member is formed with a locking structure that locks onto the side portion of the elongated member to prevent the elongated member from coming off the engagement hole, thereby providing the excellent effect of preventing the elongated member from coming off even when a large external force is applied.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028] The fixing device according to the embodiment is a fixing device for fixing a supported object to a long member such as a hanging member 10, and comprises a support part for supporting the supported object, a base to which the support part is attached on one side, an attachment body provided on the other side of the base and having an engaging part whose abutting end abuts and engages with the long member introduced into the engaging hole from the opening, and a biasing member that biases the long member from the one end side to the abutting end side within the engaging hole, and the biasing member has a locking structure formed therein that locks onto the side portion of the long member to prevent the long member from coming off the engaging hole.

[0029] In each of the following embodiments, the material of each part can be selected from various materials such as metal, resin, laminate, etc., but it is preferable to select at least the biasing member from a metal material that has elasticity that allows it to be securely attached to the hanging member (long member).

[0030] [First embodiment] 1 to 8 are explanatory diagrams of a first embodiment of the present invention.

[0031] Fig. 1 shows the fixture alone, Fig. 2 shows the fixture attached to a hanging member, and Fig. 3 is an explanatory diagram of a state in which a long object is placed on the fixture. Figs. 5 to 8 are explanatory diagrams of the function of the fixture.

[0032] As shown in Figures 1 to 3, this relates to a fixture for attaching and supporting a support part 14 consisting of a support band that supports one or more supported objects 12 (shown in Figure 3), such as pipes, to a hanging hanging member (corresponding to a "long member") 10. In the first embodiment, the hanging member 10 has an upper part fixed to a structural body such as a ceiling slab of a building (not shown), and the other part hanging downward, and in the following explanation, the top and bottom of the fixture refer to the top and bottom when installed on the hanging member 10.

[0033] The fixing device of the first embodiment comprises a support portion 14 consisting of a support band that supports the supported object 12, a plate-shaped base 16 to one side of which the support portion 14 is fixed, an attachment body 22 provided on the other side of the base 16 and having engaging portions 20, 20 whose abutting ends 18b, 18b abut and engage with the hanging member 10 introduced into the engaging holes 18, 18 from the openings 18a, 18a, and a biasing member 24 that elastically biases the hanging member (long member) 10 from the one end 18c, 18c side toward the abutting end 18b, 18b side within the engaging holes 18, 18.

[0034] In the first embodiment, the biasing member 24 is formed with a locking structure 26 consisting of a recess that locks onto the side surface of the suspending member to prevent the suspending member from coming off the engagement holes 18, 18.

[0035] The mounting body 22 has upper and lower engaging portions 20, 20 which protrude from positions spaced apart above and below the base 16 (in the direction along the length of the hanging member 10) to the side opposite the mounting side of the support portion 14, and which have engaging holes 18, 18 formed therein to allow the hanging member 10 to be introduced through openings 18a, 18a on one side of the width of the base 16 and engage with the hanging member 10.

[0036] The biasing member 24 biases the suspending member 10 (located within the engagement holes 18, 18) in a direction away from the base 16. The biasing member 24 also has a locking structure 26 formed therein, which is a recess into which the side surface of the suspending member 10 is fitted when the suspending member 10 is located within the engagement holes 18, 18, preventing the suspending member 10 from moving in the direction of the openings 18a, 18a and preventing it from coming off the engagement holes 18, 18.

[0037] The hanging member 10 is a fully threaded long bolt (hanging bolt or the like) that is suspended and fixed to the architectural structure.

[0038] The support part 14 comprises a main body 14a formed by bending the main body 14a so that it is roughly U-shaped in a side view, with an inlet 14a1 for introducing the supported object 12 from above, and a lid member 14b that can open and close the inlet 14a1 above the main body 14a. The widthwise ends of the main body 14a and the lid member 14b are bent and reinforced. The end of the lid member 14b opposite the base 16 is rotatably connected to the main body 14a by a hinge 14h, and the side end of the base 16 is hooked onto a notch or other suitable fastening structure 14c that can be locked and unlocked.

[0039] In the mounting body 22, the base 16 is made of metal and has a roughly band-like shape that extends vertically along the hanging member 10 when mounted. The base 16 and the upper and lower engaging portions 20 are integrally formed by bending or the like into a roughly U-shape when viewed from the side so that the upper and lower engaging portions 20 protrude from the upper and lower ends of the base 16 on the side opposite the mounting side where the support portion 14 of the base 16 is fixed. The upper and lower engaging portions 20 may also be fixed to the base 16 by welding or the like to form the mounting body 22.

[0040] In addition, the support part 14 is located on one side of the base part 16, and the biasing member 24 is located on the other side, and the support part 14 and the biasing member 24 are fixed to the base part 16 with various fixing members 30 such as rivets or fastening with bolts and nuts.

[0041] In the embodiment, the engaging portion 20 protrudes toward the one end 18c near the opening 18a, and has a locking portion 18d that makes the distance of the opening 18a smaller than the distance between the one end 18c and the abutting end 18b. When the suspending member (long member) 10 in the engaging hole 18 moves toward the opening due to an external force while being biased by the biasing member 24, the locking portion 18d restricts the movement of the suspending member 10.

[0042] Specifically, the upper and lower engagement portions 20, 20 are each formed in a roughly C-shape with the engagement holes 18, 18 notched out. In the upper and lower engagement portions 20, 20, one end 18c, 18c on the support portion 14 side, inside the vicinity of the openings 18a, 18a of the engagement holes 18, 18, is formed parallel to the width direction of the base 16, and the portion opposite the support portion 14 is formed slightly wider as if gouged out, and abutment ends 18b, 18b (locking claws) with tapered tips are formed in the gouged portion so as to engage with the threads of the hanging member 10. In addition, locking portions 18d, 18d are formed near the openings 18a, 18a from the gouged portion toward the support portion 14, protruding in an L-shape.

[0043] The urging member 24 has an introduction end 28 formed continuously with the locking structure 26 consisting of a recess, which is used to press the urging member 24 with the hanging member 10 when introducing the hanging member 10 from the openings 18a, 18a into the engagement holes 18, 18.

[0044] Specifically, the urging member 24 is formed integrally with the locking structure 26 consisting of a recess, continuing from the introduction end 28, and is located between the upper and lower engagement portions 20, 20, and is made entirely of an elastic material such as metal. The introduction end 28 is formed into a slope that moves away from the base 16 as it approaches the locking structure 26 consisting of the recess, and the locking structure 26 is formed at a position closer to the base 16 than the terminal end 28e of the introduction end 28.

[0045] In the biasing member 24, locking claws 26a, 26a that lock onto the threads of the suspending member 10 are formed to protrude from both ends of the locking structure 26 in the vertical direction.

[0046] The biasing member 24 is formed by bending a metal plate material with a notch (notch 24c) in the center of its width into a V-shape when viewed from above. On the side of the base 16 (support part 14) with the bent part 24a as the boundary, a flat part 24b fixed to the base 16 by a fixing member 30 and an operating part 32a are formed, while on the opposite side of the base 16, an introduction end 28, a locking structure 26, and an operating part 32b are formed.

[0047] The operating portion 32a is formed so as to be spaced a few millimeters from the base 16 via a step portion from the flat portion 24b. When an operator pinches and applies pressure to both operating portions 32a, 32b to bring them closer together, the introduction end 28 bends to approach the flat portion 24b, allowing the suspending member 10 to be introduced into the engagement hole 18, making it easy for the operator to handle.

[0048] Because the biasing member 24 has a V-shape centered on the bending point 24a, it can be elastically bent and deformed from the bending point 24a. Meanwhile, the locking structure 26, which is made up of a recess, is supported up to the bending point 24a by the linear introduction end 28, making it difficult for the locking structure 26 to deform in the direction approaching the openings 18a, 18a, and therefore can firmly restrict movement of the suspending member 10 fitted into the locking structure 26. Note that as long as the locking structure 26 and introduction end 28 can restrict movement of the suspending member 10, they can be formed into various shapes, such as bent.

[0049] The introduction end 28 has a roughly U-shape from the bending point 24a toward the locking structure 26 due to the cutout point 24c, and a tool can be attached to the fixing member 30 through the cutout point 24c to fix the fixing member 30 (specifically, by tightening with bolts and nuts or riveting).

[0050] In addition, the introduction end 28 has two slopes formed that move away from the base 16 as it approaches the locking structure 26, so the hanging member 10 can be introduced while being supported at two points in the lengthwise direction, making it less likely to shift position.

[0051] The recess of locking structure 26 is formed at a position closer to base 16 than terminal end 28e of introduction end 28. Specifically, introduction end 28 moves away from base 16, and at terminal end 28e, one end bends toward base 16 and connects to locking structure 26 consisting of a recess, and then extends from locking structure 26 away from base 16 and connects to flat operating portion 32b. Notch 24c divides introduction end 28 and locking structure 26 into two in the width direction, continues halfway through operating portion 32b, and is formed integrally and flat with operating portion 32b.

[0052] When the hanging member (long member) 10 in the engagement hole of the urging member 24 is deformed by an external force and moves toward one end 18c, the hanging member 10 abuts against one end 18c and is positioned (see Figure 6(b)). At the same time, when the urging member 24 is deformed, the urging member 24 is structured to be deformable to a rear position away from the abutting end 18b than the one end 18c (see Figure 5).

[0053] Specifically, when the bending portion 24a of the biasing member 24 is bent due to elastic deformation, the range of movement is set as shown in Fig. 5, such that when the biasing member 24 moves away from the abutting end 18b toward the base 16, the leading end 28 moves so as to bend past the one end 18c and approach the base 16. Furthermore, when the biasing member 24 is deformed by an external force and moves toward the one end 18c, the suspending member 10 abuts against the one end 18c and is positioned accordingly.

[0054] [Operation and effect of the first embodiment] FIG. 5 shows the operation state when attaching and detaching the fastener to the hanging member 10.

[0055] As shown in FIG. 5, when the biasing member 24 is deformed, the biasing member 24 is configured to be deformed to a rear position that is farther away from the contact end 18b than the one end 18c.

[0056] When attaching or detaching the fixing device to the suspension member 10, as shown in Figure 5, the worker pinches the operating parts 32a and 32b with their fingers and applies force to deeply bend and deform the operating parts 32a and 32b so that they approach each other against the elastic force of the biasing member 24.

[0057] 5, by bending and deforming the biasing member 24, the locking structure 26 is adjacent to or enters the support portion 14 side from the introduction end 28 of the biasing member 24 rather than the position of the one end 18c, 18c on the support portion 14 side within the engagement holes 18, 18, and the suspending member 10 can be easily introduced into the engagement holes 18, 18 from the openings 18a, 18a. This allows the suspending member 10 to be attached to and detached from the engagement holes 18 through the openings 18a, 18a.

[0058] As another method for attaching the fixture, the fixture can be attached to the suspending member 10 by pushing in without holding the operating portions 32a, 32b.

[0059] In other words, by fitting the suspending member 10 into the openings 18a and applying force to the fastener to push the suspending member 10 into the engagement holes 18, the suspending member 10 enters between the end of the openings 18a (the side of the support portion 14) on the locking portions 18d and 18d side and the introduction end 28. The suspending member 10 then slides down the slope of the introduction end 28, pushing open the biasing member 24, and the suspending member 10 passes the end portion 28e and fits into the engagement structure 26 consisting of a recess, as shown in Figures 2 and 6(a), completing the attachment of the fastener. At this time, the suspending member 10 is biased and pressed by the biasing member 24 toward the opposite side of the support portion 14, so that the abutting ends 18b and 18b of the suspending member 10 engage with the threads of the suspending member 10, and the vertical position of the fastener is fixed relative to the engagement holes 18, preventing misalignment.

[0060] When installing the supported object 12 on the fixture fixed to the hanging member 10, as shown in Figure 3, the cover member 14b of the support part 14 is opened, the supported object 12 is introduced into the main body part 14a, and the cover member 14b is closed to complete the installation.

[0061] When the suspension member (long member) 10 in the engagement hole 18 of the urging member 24 is deformed by an external force and moves toward one end 18c, the suspension member 10 comes into contact with one end 18c and is positioned as shown in Figure 6(b), thereby preventing the suspension member 10 from coming off the engagement hole 18.

[0062] When a large external force is applied, such as during an earthquake, the weight of the supported object 12 causes the support part 14 to vibrate, and as the support part 14 moves, the suspension member 10 presses the biasing member 24 toward the support part 14. As shown in Figure 6(b), the biasing member 24 bends toward the support part 14 due to the pressing force. The suspension member 10 hits the end faces of the ends 18c, 18c on the support part 14 side of the engagement holes 18, 18, and is unable to move any further.

[0063] Furthermore, when the movement of the support portion 14 causes the hanging member 10 to move to the openings 18a, 18a of the engagement holes 18, 18 and press the spring member 24, as shown in Figures 7 and 8, the hanging member 10 is fitted into the locking structure 26 consisting of a recess within the engagement holes 18, 18, and the introduction end 28 is unlikely to elastically deform toward the bending point 24a, so the movement of the hanging member 10 in the direction of the openings 18a, 18a is restricted by the spring member 24 that is continuous with the locking structure 26, preventing the hanging member 10 from coming off the engagement holes 18, 18.

[0064] 8, in the first embodiment, in the biasing member 24, the terminal end 28e of the introduction end 28 forms a convex portion that protrudes toward the abutting end 18b side adjacent to the recess of the locking structure 26. With this configuration, when the hanging member 10 (long member) in the engagement hole 18 is deformed by an external force such as an earthquake and moves toward the one end side, the interval δ narrowed by the convex portion of the terminal end 28e of the opening is smaller than the outer diameter D of the hanging member 10 (long member). In this case, when the hanging member 10 (long member) abuts against one end 18c, the distance δ between the locking portions 18d, 18d of the engagement holes 18, 18 and the terminal end 28e of the introduction end 28 is narrower than the outer diameter D of the hanging member 10 (long member), so that the hanging member 10 abuts against the locking portions 18d, 18d and the terminal end 28e, 28e, and the hanging member 10 does not pass through the distance δ any further, thereby ensuring reliable regulation.

[0065] Therefore, even if a strong external force such as that during an earthquake is applied to the hanging member 10 (long member) and the supported object 12, they can be reliably prevented from coming off the engaging holes 18, 18.

[0066] Second Embodiment FIG. 9 is an explanatory diagram of a fixture according to the second embodiment.

[0067] The fixture according to the second embodiment has the same structure as the first embodiment, including the support portion 14, base portion 16, and upper and lower engaging portions 20, and the like, and the like parts are denoted by the same reference numerals.

[0068] As shown in Figure 9, in the second embodiment, the biasing member 24A is a fixing device in which an introduction end 28A for pressing the biasing member 24A by the hanging member 10 (corresponding to a long member, not shown as it is similar to the hanging member 10 of the first embodiment) when the biasing member 24A is introduced into the engagement holes 18, 18 from the openings 18a, 18a is formed continuously with the locking structure 26A consisting of a recess, and the introduction end 28A is formed approximately parallel to the base 16, and the locking structure 26A is formed at a position closer to the base 16 than the terminal end 28Ae of the introduction end 28A.

[0069] The mounting portion 24Aa is flat and in close contact with the base 16 and fixed by a fixing member 30. The mounting portion 24Aa has a width that fits within the width of the base 16.

[0070] The openings 18a, 18a side in the width direction of the base 16 is one side (denoted by the symbol "W1"), and the opposite side is the other side (denoted by the symbol "W2").

[0071] The continuous portion 24Ab continues at an end of the other side W2 of the attachment portion 24Aa at an angle of 90 degrees in a direction away from the support portion 14 (indicated by the symbol "D1").

[0072] The urging member 24A is composed of a flat mounting portion 24Aa that contacts the base 16 and is fixed by a fixing member 30, a continuous portion 24Ab that rises vertically in a direction D1 away from the support portion 14 at the other side W2 of the base 16 described below, where the mounting portion 24Aa bends, and an engaging structure 26A that is formed at the extending end of the continuous portion 24Ab by bending toward one side W1 of the base and recessing toward the base 16, and an introduction end 28A that is continuous with one side W1 of the engaging structure 26A and has an approximately U-shaped cross section when viewed in the vertical direction (when viewed in the axial direction of the hanging member 10).

[0073] In the embodiment, each part of the urging member 24A is formed by bending a metal plate material of the same thickness by press forming, etc. This configuration is one example, and it is also possible to form each part or part separately and fix them by welding, etc.

[0074] The locking structure 26A is continuous with the tip of the continuous portion 24Ab, and an introduction end 28A extends from the locking structure 26A to one side W1. The tip of the introduction end 28A extends forward from one side end of the base portion 16.

[0075] At the introduction end 28A, the bottom 26Ab of the locking structure 26A, which is a recess, is recessed toward the base 16 side from the sliding surface 28As along which the suspending member 10 slides during introduction.

[0076] When attaching the fixture according to the second embodiment to the suspension member 10, the worker bends the introduction end 28A toward the base 16 and presses the suspension member 10 against the sliding surface 28As. The suspension member 10 is then pushed into the engagement holes 18, 18 through the openings 18a, 18a, and within the engagement holes 18, 18, the suspension member 10 is fitted into and held by the locking structure 26A.

[0077] The suspending member 10 fits into the locking structure 26A within the engagement holes 18, 18, and the terminal end 28Ae of the introduction end 28A protrudes from the engagement holes 18, 18 relative to the locking structure 26A to prevent it from falling off. The recess of the locking structure 26A fits snugly against the suspending member 10, providing a stable biasing force and a stable anti-fall-off force.

[0078] Therefore, the movement of the suspending member 10 in the direction of the openings 18a, 18a is restricted by the biasing member 24 continuous with the locking structure 26, and the suspending member 10 can be reliably prevented from coming off the engagement holes 18, 18. Even if the suspending member 10 attempts to move from the locking structure 26A toward the introduction end 28A, it can be prevented from coming off by abutting the locking portions 18d, 18d on the opening side.

[0079] Third Embodiment 10 is an explanatory diagram of a fixture according to a third embodiment. The fixture according to the third embodiment has the same structure as the first embodiment, including the support portion 14, base portion 16, and upper and lower engagement portions 20, and the like, and the like parts are denoted by the same reference numerals.

[0080] As shown in Figure 10, the fixing device according to the third embodiment comprises a base 16 to which a support part 14 having the same structure as that of the first embodiment is fixed, and an attachment body 22 having upper and lower engagement parts 20, 20 in which engagement holes 18, 18 are formed to engage with the hanging member 10 (the central axis of which is shown by a two-dot chain line).

[0081] The fixing device according to the third embodiment is a fixing device that includes a biasing member 24B between the upper and lower engagement portions 20, 20, from one end 18c side to the abutting end 18b side, specifically, that biases the suspension member 10 in the engagement holes 18, 18 in a direction away from the base 16, and a fall prevention member 34 that is separate from the biasing member 24B and has a locking structure 26B consisting of a recess that is formed by fitting the side portion of the suspension member 10 in the engagement holes 18, 18, and that biases the suspension member 10 in a direction away from the base 16 to prevent the suspension member 10 from coming off the engagement holes 18, 18.

[0082] The biasing member 24B is formed by bending a metal plate material with a notch (notch portion 24Bc) in the widthwise center into a V-shape when viewed from the vertical direction. The biasing member 24B is formed with a flat portion 24Bb and an operating portion 32Ba that abut against the base portion 16 from the support portion 14 side and are fixed by the fixing member 30, with the bending portion 24Ba as the boundary, while on the opposite side of the base portion 16, the sloped introduction end portion 28B is formed flat and integral from the operation portion 32Bb to the operation portion 32Bb. The introduction end portion 28B has locking claws 28Ba, 28Ba at the top and bottom ends to lock onto the screw threads of the hanging member 10.

[0083] The fall-off prevention member 34 is an elastically deformable, generally band-shaped member having a locking structure 26B formed midway along its length, and its length extends obliquely relative to the width direction of the base 16. The locking structure 26B has slopes 34b at the front and rear.

[0084] The biasing member 24B and the fall-off prevention member 34 are integrally formed by pressing a metal plate material.

[0085] When attaching the fixing device according to the third embodiment to the suspension member 10, the worker grasps the operating portions 32Ba, 32Bb, bends the introduction end 28B toward the base portion 16, presses the suspension member 10 against the sliding surface 28Bs, and pushes the suspension member 10 through the openings 18a, 18a and into the engagement holes 18, 18. At the same time, the suspension member 10 fits into the locking structure 26B within the engagement holes 18, 18. Because the suspension member 10 fits into the locking structure 26B of the fall-off prevention member 34 and is positioned within the engagement holes 18, 18, the fall-off prevention member 34 restricts the movement of the suspension member 10 in the direction of the openings 18a, 18a, and reliably prevents the suspension member 10 from coming off the engagement holes 18, 18.

[0086] In the fixing device of the third embodiment, the biasing member 24B and the anti-fall-off member 34 are formed separately, so that after the fixing device is attached to the hanging member 10, the attached height can be adjusted by loosening the biasing member 24B.

[0087] At this time, the worker pinches the operating portions 32Ba, 32Bb to weaken the biasing force, releasing the engagement between the suspending member 10 and the abutment end portion 18b and the locking claws 28Ba, 28Ba, and adjusting the height of the suspending member 10. Because the biasing force of the biasing member 24B is merely weakened without deforming the fall-off prevention member 34, the suspending member 10 does not come off the locking structure 26B and therefore moves only up and down within the engagement holes 18 of the upper and lower engagement portions 20, 20, without moving toward the openings 18a, 18a. Therefore, the fixing device does not fall off from the suspending member 10.

[0088] Furthermore, since the elastic force of the biasing member 24B and the elastic force of the fall-off prevention member 34 can be set separately, an appropriate mounting pressure can be achieved.

[0089] [Fourth embodiment] 11 is an explanatory diagram of a fixture according to a fourth embodiment. The fixture according to the fourth embodiment has the same structure as the support portion 14, base portion 16, etc. of the first embodiment, and the same parts are denoted by the same reference numerals.

[0090] As shown in FIG. 11, the fixture according to the fourth embodiment comprises a base 16 to which the support portion 14 is fixed, and an attachment body 38 having upper and lower engagement portions 36U and 36D that engage with the hanging member 10 (the central axis of which is shown by a two-dot chain line).

[0091] The upper engagement portion 36U has an engagement hole 36Ua formed therein, the opening of which faces the other widthwise side (indicated by "W2") of the base 16. The lower engagement portion 36D has an engagement hole 36Da formed therein, the opening of which faces one widthwise side (indicated by "W1") of the base 16. The engagement holes 36Ua, 36Da of each engagement portion 36U, 36D are generally U-shaped, and the respective openings face in opposite directions, i.e., the W2 and W1 directions.

[0092] The fixture is configured such that a biasing member 40 that applies a biasing force to the suspending member 10 and a fall prevention member 42 that prevents the suspending member 10 from falling off are integrally formed between the engaging portions 36U, 36D, and the biasing member 44 is fixed to the base 16 by the fixing member 30. The biasing member 44 is formed by press-forming an elastic metal plate material, but each part or part can also be formed separately and integrated by welding.

[0093] Specifically, the biasing body 44 comprises a flat portion 44a fixed to the base 16 side, and a tongue-shaped portion 44b (an elastic plate material at the portion where the biasing member 40 and the anti-slip member 42 are formed) that is bent obliquely from the upper and lower ends of the flat portion 44a in a direction away from the base 16.

[0094] The tongue-shaped portion 44b has a recess 40a (corresponding to a "locking structure") cut out in a rectangular shape from the tip, and the biasing member 40 is formed from the recess 40a on the side closer to the flat portion 44a. In this case, cuts 40b, 40b are formed from both ends of the width of the recess 40a toward the flat portion 44a. The portion sandwiched between these cuts 40b, 40b is partially separated from the rest by the cuts 40b, 40b, becoming the elastically deformable biasing member 40, which functions to elastically press the suspending member 10 attached within the recess 40a.

[0095] The anti-slip member 42 is a wall-like portion of the tongue-shaped portion 44b adjacent to the cut-out recess 40a, and is formed as a portion located on the opening side of the engagement holes 36Ua, 36Da. When the suspending member 10 in the engagement holes 36Ua, 36Da attempts to move in the width direction (W2, W1 direction) of the base 16, the anti-slip member 42 abuts against the suspending member 10 to restrict further movement and prevent it from falling out of the recess 40a.

[0096] At the tongue-shaped portion 44b, the biasing member 40 and the fall-off prevention member 42 are separated by notches 40b, 40b, and the edges of the biasing member 40 and the fall-off prevention member 42 surround the recess 40a.

[0097] Therefore, the fall prevention member 42 is formed as a wall-like portion adjacent to the recess 40a. The wall-like portion also has a bulging portion 40c that protrudes toward the opening side of the engagement holes 36Ua and 36Da and extends flush with the surface. This bulging portion 40c is configured so that an operator can press the bulging portion 40c with their fingers to bend the fall prevention member 42 toward the support portion 14, thereby allowing the suspending member 10 to be installed in the recess 40a.

[0098] In the fastener of the fourth embodiment, when the suspending member 10 is attached to the recess 40a in the elastic biasing member 44, the anti-slip members 42 forming the edges of the recess 40a reliably restrict the movement of the suspending member 10, thereby preventing it from falling off, and at the same time, the biasing members 40 press the suspending member 10 in the D1 direction against the inner circumferential surfaces of the engagement holes 36Ua, 36Da of the engagement portions 36U, 36D. By providing tapered portions on the edges of the inner circumferential surfaces of the engagement holes 36Ua, 36Da that abut and engage with the threads, the edges act as locking pawls, thereby providing a positioning function.

[0099] Fifth Embodiment FIG. 12 is an explanatory diagram of a fixture according to a fifth embodiment.

[0100] As shown in Figure 12, the fixing device according to the fifth embodiment comprises a base 16 to which a support part 14 having the same structure as that of the fourth embodiment is fixed, and an attachment body 38 having upper and lower engagement parts 36U and 36D in which engagement holes 36Ua and 36Da are formed to engage with the hanging member 10 (the central axis of which is shown by a two-dot chain line), and similar parts are given the same symbols.

[0101] The fixture has a biasing body 54, which is an integrally formed biasing member 50 that applies a biasing force to the suspending member 10 and a fall-off prevention member 52 that prevents the suspending member 10 from falling off, fixed to the base 16 by the fixing member 30 between the engaging portions 36U, 36D. The biasing body 54 is formed by press-forming an elastic metal plate, but each part or part can be formed separately and then integrated by welding. The holding portion 50b can be integrally formed, or a separate member can be fixed together by welding or the like.

[0102] Specifically, the biasing body 54 comprises a flat portion 54a fixed to the base 16 side, and a biasing member 50 (having a fall prevention member 52 formed thereon) which is bent obliquely from the upper and lower ends of the flat portion 54a in a direction away from the base 16.

[0103] The biasing member 50 is made of an elastic plate material that protrudes obliquely in a direction away from the base 16. A recess 50a is formed on the tip side of the biasing member 50 (the side away from the base 16) toward the base 16 side of the biasing member 50, into which the side surface of the suspending member 10 is fitted to prevent the suspending member 10 from disengaging from the upper and lower engagement holes 36Ua and 36Da. A cylindrical side surface-shaped holding portion 50b that holds the side surface of the suspending member 10 is provided in the recess 50a along the length of the suspending member 10.

[0104] Wall-like portions that support the suspending member 10 are formed as anti-fall members 52 on both sides of the recess 50a of the biasing member 50 in the width direction.

[0105] The suspending members 10 fit into the recesses 50a in the engagement holes 36Ua, 36Da, and the retaining portions 50b fit the surfaces of the suspending members 10 in the recesses 50a, and the suspending members 10 are held in place by a stable biasing force from the biasing members 50, preventing axial movement of the suspending members 10. At the same time, the suspending members 10 are supported from both sides in the width direction by the fall-off prevention members 52, so that the suspending members 10 can be reliably prevented from falling off the engagement holes 36Ua, 36Da even when subjected to vibrations such as an earthquake.

[0106] Sixth Embodiment FIG. 13 is a three-dimensional perspective view illustrating a fixture according to a sixth embodiment of the present invention.

[0107] The fixing device of the sixth embodiment relates to a cross fitting for fixing intersecting fully threaded bolts together, and as shown in Figure 13, is a fixing device as a cross fitting for fixing a long member 10 made of a fully threaded bolt and a supported object 112 also made of a fully threaded bolt at their intersection.For example, when hanging ceiling-suspended equipment with a suspension bolt, it can be used as a cross fitting for fixing fully threaded bolts for diagonal members that are connected to the suspension bolt to prevent the equipment from swaying (in the sixth embodiment, this corresponds to the long member 10 and the supported object 112).

[0108] The fixture of the sixth embodiment mainly comprises a support portion 114 that supports the supported object 112, and a base portion 16 to which the support portion 114 is attached on one side. The remaining portions, such as the base portion 16, the engaging portion 20, the mounting body 22, and the biasing member 24, have the same structure as the fixture of the first embodiment, and therefore the same parts are given the same symbols.

[0109] The fixture of the sixth embodiment is provided with a support portion 114 including a base portion 116, an engaging portion 120, an attachment body 122, a biasing member 124, etc., instead of the support portion consisting of the support portion 14 of the first embodiment.

[0110] This support portion 114 has the same structure as the fixture of the first embodiment, and the same parts are given reference numerals with 100 added, such as an engagement portion 120, an attachment main body 122, and a biasing member 24.

[0111] In addition, the base 16 of the mounting body 22 and the base 116 of the mounting body 122 of the support part 114 are placed back to back, and are fixed to each other rotatably by the fixing member 30 with each longitudinal direction rotated at an arbitrary angle.

[0112] In detail, the support part 114 of the fixing device comprises a base part 116, and an attachment body 122 which is provided so as to protrude from one side of the base part 116 (the side opposite the elongated member 10) and has engaging parts 120, 120 whose abutting ends 118b, 118b abut and engage with the supported object 112 which is made of a long-threaded bolt introduced into the engaging holes 118, 118 from the openings 118a, 118a, and a biasing member 124 which biases the supported object 112 from the side of the one end 118c, 118c to the side of the abutting end 118b, 118b within the engaging holes 118, 118, and the biasing member 124 is formed with a locking structure 126 consisting of a recess which locks onto the side part of the supported object 112 to prevent the supported object 112 from coming off the engaging holes 118, 118.

[0113] The fastener of the sixth embodiment as a whole provides the same effects as the fastener of the first embodiment, and the support portion 114 also provides the same effects as the fastener, allowing for easy attachment and detachment of the long bolts of the supported object 12 and providing a retaining function. In addition, the base portion 16 and the support portion 114 are rotatable around the fixing member 30. By making the fixing member 30 rotatable to a certain extent, construction can be carried out by aligning the positions of the engaging portions 120, 120 to match the intersection angle of the long member 10 and the supported object 112, and then fixing the fixing member 30, thereby making it possible to easily fix the long member 10 and the supported object 112 together by easily matching the intersection angle of the diagonal members.

[0114] Seventh Embodiment FIG. 14 is a three-dimensional perspective explanatory view of a fixing device according to a seventh embodiment.

[0115] As shown in FIG. 14, the fixing device according to the seventh embodiment has a hook-shaped support portion 214 that can hook and fix a rope or cloth-like supported object (not shown), and the configuration of the other parts such as the base portion 16, engagement portion 20, mounting body 22, and biasing member 24 is the same as that of the first embodiment, and similar parts are given the same symbols.

[0116] The support portion 214 is integrally provided with a main body 214a extending linearly, and a support end 214b which is bent in an arc at the lower end (an example of one end) of the main body 214a to form a hook-shaped support end.

[0117] According to the fixing device of the seventh embodiment, the support end 214b can be hooked onto the eyelet hole of a flexible duct having eyelets as the supported object, for example, and the flexible duct can be easily hung from a hanging member (long member), so that the fixing device can be fixed to an appropriate hanging member to fix the supported object.

[0118] Eighth Embodiment Figures 15 to 18 are explanatory diagrams of a fastener according to the eighth embodiment. Figure 15 is a perspective explanatory diagram of the state at the completion of installation with the hanging member (long member) attached, Figure 16 is a perspective explanatory diagram of the state at the time of removal, and Figure 17 is a perspective explanatory diagram of the state at the time of an earthquake. Figure 18 (a) shows a plan view of the state at the completion of installation, (b) shows a plan view of the state at the time of removal, and (c) shows a plan view of the state at the time of an earthquake.

[0119] The fixture according to the eighth embodiment is a fixture for fixing a supported object such as a pipe to a long member such as a hanging member 10, and differs from the first embodiment in that the opening 318a of the engagement hole 318 in each of the upper and lower engagement portions 320 is opened in a direction perpendicular to the outer side of the base 316 of the mounting body 322, in other words, the opening 318a is opened on the side opposite to the mounting side of the support portion 14. Note that the same reference numerals are used for the same parts of the fixture, support portion 14, etc. as in the first embodiment.

[0120] The fixing device of the eighth embodiment comprises a support part 14 that supports a supported object (not shown) such as a pipe, a base 316 to which the support part 14 is attached on one side, an attachment body 322 that is provided on the other side of the base 316 and has a pair of engaging parts 320 spaced apart vertically, the abutting ends 318b of which abut and engage with the hanging member 10 introduced into the engaging hole 318 from the opening 318a facing the other side, and a biasing member 324 that biases the hanging member 10 from the one end 318c side to the abutting end 318b side within the engaging hole 318, and the biasing member 324 is formed with a locking structure 326 that engages with the side part of the hanging member 10 to prevent the hanging member 10 from coming off the engaging hole 318.

[0121] The biasing member 324 has a protrusion 326a on the locking structure 326. As shown in Fig. 18, the protrusion 326a is formed by bending or the like so as to rise at an angle of approximately 45 to 90 degrees relative to the main body 324a of the biasing member 324. The locking structure 326 functions to restrict movement of the suspending member 10 in the opening direction by the base 216 side of the protrusion 326a coming into contact with the suspending member 10.

[0122] The function of the fixing device will be explained. When attaching or detaching the fixing device to the suspension member 10, as shown in Figures 16 and 18(b), the worker grasps the operating portion 332 of the biasing member 324 with a tool or the like, bends the convex portion 326a of the biasing member 324 to a position beyond one end portion 318c, and attaches the suspension member 10 to the engagement hole 318.

[0123] When attached, as shown in Figures 15 and 18(a), the elastic force of the biasing member 324 presses the suspending member 10 against the abutting end 318d, which then bites into the suspending member 10, ensuring that the fixture is securely fixed.

[0124] When an external force such as during an earthquake is applied, as shown in Figures 17 and 18(c), even if the hanging member 10 (long member) in the engagement hole 318 deforms the biasing member 324 due to the external force and moves toward one end 318c, the gap δ narrowed by the convex portion 326a of the opening 318a is smaller than the outer diameter D of the long member.

[0125] When the suspending member 10 is moved by an external force and hits one end 318c, the position is restricted by one end 318c and it does not further push open the biasing member 324. Furthermore, even if it moves toward the opening 318a, it hits the protrusion 326a, which prevents it from moving further toward the opening and prevents it from coming off.

[0126] Although the orientation of the opening 18a in the first embodiment is different from that of the opening 318a in the eighth embodiment, in the present invention, by devising the shape of the biasing member, the base can be installed at any location on the abutting end side, one end side, or the opposite side of the opening. In this case, the positional relationship between the opening, abutting end side, one end, and the direction of the biasing force remains unchanged.

[0127] Ninth Embodiment 19 and 20 are explanatory diagrams of a fixing device according to a ninth embodiment.

[0128] The fixture according to the ninth embodiment has the same structure as the first embodiment, such as the support portion 14, base portion 16, and upper and lower engaging portions 20, and the like, and the like parts are denoted by the same reference numerals.

[0129] As shown in Figures 19 and 20, the fixing device of the ninth embodiment comprises a support band (support portion) 14 that supports the supported object 12, a plate-shaped base 16 to which the support portion 14 is fixed on one side, an attachment body 22 that is provided on the other side of the base 16 and has engagement portions 20, 20 whose abutting ends 18b, 18b abut and engage with the hanging member 10 introduced from the openings 18a, 18a into the engagement holes 18, 18 in a direction along the width direction of the base 16, and a biasing member 424 that elastically biases the hanging member (long member) 10 from one end 18c, 18c side toward the abutting ends 18b, 18b side within the engagement holes 18, 18.

[0130] In the ninth embodiment, a biasing member 424 is formed with a locking structure 426 having a protrusion 426a that locks onto the side surface of the suspending member 10 to prevent the suspending member from coming off the engagement holes 18, 18.

[0131] Specifically, the biasing member 424 is formed by bending a metal plate material with a notch (notch 424d) cut out in the center of its width into a V-shape when viewed from the up-down direction. A flat portion 424b fixed to the base 16 by the fixing member 30 and an operating portion 432a are formed continuously via a step 424b1, with the bent portion 424a as the boundary.

[0132] Meanwhile, in the biasing member 424, a flat main body 424c continues from the bent portion 424a on the opposite side of the base 16, and a protrusion 426a of the locking structure 426 is formed in a bent state at a midpoint of the main body 424c, protruding toward the abutment end 18b on the opposite side of the base 16. The protrusion 426a is bent from its tip toward the base 16, returns to the main body 424c, and continues to the operating portion 432b. In other words, the protrusion 426a is formed to protrude in a direction away from the base 16 relative to the main body 424c and the operating portion 432b.

[0133] Here, biasing member 424 is provided with protrusion 426a as locking structure 426. Protrusion 426a is formed by bending or the like on the operating portion 432b side of main body 424c of biasing member 424 so as to rise at an angle ranging from approximately 45 to 90 degrees relative to main body 424c.

[0134] Due to this rising angle of the convex portion 426a, when an external force such as an earthquake is applied, the hanging member 10 (long member) comes into contact with the convex portion 426a, causing the locking structure 426 to perform its locking function, thereby effectively preventing the hanging member 10 from coming off the engagement hole 18.

[0135] In addition, the bending point 424a side of the convex portion 426a has a gentler rise angle relative to the main body 424c than the operating portion 432b side, making it easier for the suspending member 10 to climb over the convex portion 426a when introducing the suspending member 10 through the opening 18a.

[0136] 20, when the suspending member 10 is moved by an external force and hits one end 18c, the position is restricted by one end 18c and it does not further push open the biasing member 424. Furthermore, even if it moves toward the opening 18a, it hits the protrusion 426a, preventing it from moving further toward the opening and preventing it from coming off.

[0137] Tenth Embodiment 21A and 21B are explanatory diagrams of a fastener according to a tenth embodiment, in which Fig. 21A shows the fastener being attached and detached, and Fig. 21B shows the fastener being subjected to an external force such as an earthquake.

[0138] As shown in FIG. 21, the fixture according to the tenth embodiment has the same structure as the first embodiment, including the support portion 14, base portion 16, upper and lower engagement portions 20, and biasing member 24, and the like, and the like parts are denoted by the same reference numerals.

[0139] In the tenth embodiment, a support base 500 is provided on the base 16, with one end 500a against which the hanging member (long member) abuts when introduced into the engagement hole 8 or when an external force is applied. In the first embodiment, which is compared, one end 18c was provided inside the engagement hole 18 of the engagement portion 20 (see FIG. 5, etc.), but in the tenth embodiment, as shown in FIG. 21, one end 500a is located on the support base 500 fixed to the base 16 between the upper and lower engagement portions 20, 20.

[0140] The one end 500a is positioned so as to protrude further toward the opposite side of the base 16 than the base-side end 18c' in the engagement hole 18.

[0141] When attaching or detaching the hanging member (long member) 10, as shown in FIG. 21(a), the biasing member 24 is deformed by pinching the operating portions 32a and 32b and bending them, so that it can be introduced into the engagement hole 18.

[0142] When the hanging member (long member) 10 in the engagement hole 18 of the urging member 24 is deformed by an external force and moves toward one end 18c, the hanging member 10 abuts against one end 500a, as shown in Figure 21(b), and its position is restricted, thereby preventing it from falling off.

[0143] As shown in Figure 21(a), when the urging member 24 is deformed, such as when attaching or detaching the suspending member 10, the urging member 24 is structured to be deformable to a rear position farther away from the contact end 18b than the one end 500a, making it easy to attach or detach the suspending member 10.

[0144] The functional member of the one end portion 500a is an example that can be configured and installed in various ways other than the one end portion 18c of the first embodiment. The other configurations, functions and effects are the same as those of the first embodiment.

[0145] While the above-described embodiments are preferred embodiments of the present invention, they can be modified within the scope of the present invention. For example, in each embodiment, the support band, mounting body, and biasing member are formed as separate members and fixed using fixing members, but various modifications can be made within the scope of the present invention, such as fixing each member by other methods, such as welding, or forming them integrally.

[0146] The support band is an example of the support portion of the present invention. The engaging portion may be a pair of upper and lower engaging portions, or may be singular or plural. [Industrial Applicability]

[0147] The fastener of the present invention can be suitably used for suspension members such as suspension bolts for buildings. [Explanation of symbols]
