  The separation preventing tool 5 of FIG. 1 is plastically deformed from the side of the bolt body B, whereby the proximity portion 6c of the nut body 6 attached to the bolt body B (FIGS. 2A and 2B). And the nut body 6 is combined to form the attachment body of the present invention.

  The separation prevention tool 5 is configured by bending a rectangular flat plate made of steel by a fold line orthogonal to the longitudinal direction, and has an L shape as a whole when viewed from the direction of the extension line of the fold line.

  The upper portion of the L-shaped separation preventing device 5 is a lower end portion 5a bent downward from the uppermost portion of the L shape, a distal end lateral portion 5b which is bent and continuous to the lower end portion 5a, and becomes horizontal, and this distal end lateral portion 5b An intermediate upper wall 5c bent downward in the same direction in parallel with the tip lower end 5a.

  An accommodation recess 5i that receives and accommodates the bolt body B from the horizontal direction is formed in the distal end lateral portion 5b. The manner in which the bolt body B is accommodated in the accommodating recess 5i is as shown by the phantom lines of the two-dot chain lines in FIGS. That is, the bolt body B in the accommodated state is in a state in which the outer periphery of the bolt body B is in contact with the arc portion of the accommodating recess 5i and is sandwiched between the tip lower part 5a and the intermediate upper wall 5c with a certain interval.

  An intermediate portion of the L-shaped separation preventing tool 5 is a contact wall 5d that contacts the bolt body B in the accommodated state through a bent portion continuous with the intermediate upper wall 5c.

  The lower side portion of the L-shaped separation preventing tool 5 is bent continuously from the abutting wall 5d and extends in the horizontal direction away from the bolt body B in the accommodated state, and the bent portion extends from the end of the lower side portion 5f. Then, the upper stage part 5g extended in a horizontal direction is further provided, and the edge part of this upper stage part 5g is the most end part of the lower side part of the L-shaped separation prevention tool 5. FIG.

  The lower end 5a is provided with a fitting portion 1 which is opened at the lower end and into which a proximity portion 6c (see FIGS. 2A and 2B) of the nut body 6 attached to the bolt body B in the accommodated state is inserted. It has been. The insertion part 1 is comprised from the back | inner narrow back part 1a and the slant opening part 1b which continues to this narrow back part 1a and the opening width is gradually widened.

  This center line M is not located at the center of the width of the separation preventing device 5, and as shown in the figure, if the positions in the width direction are L1 and L2, L2> L1. Assuming that L1 = L2 simply, because of the accommodating recess 5i, the remaining width in the width direction of the tip horizontal portion 5b becomes too small, the tip horizontal portion 5b bends at this portion, and the separation prevention tool 5 becomes unusable. Because.

  On the other hand, if the center line M is set as the center in the width direction and the width itself is set so that the remaining thickness in the width direction of the tip horizontal portion 5b is not excessively small, the width becomes excessively large and the material cost increases.

The portion related to the support is referred to as a support portion 3.

  2 (a) and 2 (b), the nut body 6 is made of a steel material, and a U-shaped main body portion having an engagement protrusion 6b that engages with an outer surface screw of a bolt body B to be attached. 6a, provided with an opening 6e through which the bolt body B is inserted from the side, and with the bolt body B inserted, the main body 6a (more accurately, in order to bring the proximity portion 6c provided at the tip of the opening 6e close to each other. Is a portion of the main body 6a that is not in the shape of an arc on the side of the proximity portion 6c), and the engagement protrusion 6b is engaged with the outer surface screw of the bolt body B, and rotates relative to the bolt body B. The bolt body B is attached so as to be movable along the axial direction.

  A pair of locking grooves 6m extending in the axial direction of the bolt body B are formed outside the pair of proximity portions 6c. The engaging portion 1 of the separation preventing tool 5 is fitted into the locking concave groove 6m.

  In addition, a screw portion 6f is fixed to the nut body 6 at a position on the outer periphery of the main body portion 6a and opposite to the opening 6e so that the screw portion protrudes in the opposite direction. .

In order to attach such a nut body 6 to the bolt body B, first, as shown in FIG.
The bolt body B is received from the opening 6e of the nut body 6, and the proximity protrusion 6c is brought into a state where the engaging projection 6b is engaged with the outer surface screw of the bolt body B as shown in FIG. The nut body 6 is gripped so that the tip of the nut is held and held by a holding portion (not shown) at the tip of the tool T.

  In this state, when the dedicated tool T is tightened so that the proximity portions 6c of the nut body 6 are close to each other, the nut body 6 is plastically deformed, and is attached as in the nut body 6 of FIG. It becomes. In this figure, the nut body 6 is attached to the bolt body B, and the proximity of the bolt body B and the proximity portion 6c and the threaded portion 6f are in a positional relationship projecting in the opposite direction. I understand.

  3 (a) to 3 (c) are explanatory views of an example of a method of use in which the attachment device composed of the separation prevention device of FIG. 1 and the nut body of FIG. 2 is attached to the bolt body, and FIG. (A)-(c) is explanatory drawing of an example of the usage method which attaches and uses an attachment tool to a bolt body following FIG. 3, (d) is (c) from the direction of an arrangement | positioning body. FIG.

  Accordingly, the same parts as those already described are denoted by the same reference numerals and redundant description is omitted. Moreover, in order to avoid complexity, there are cases where all symbols are not repeated.

  In addition, about the attachment to the bolt body B of the nut body 6 which comprises the attachment body 10 in combination with the separation prevention tool 5, it already demonstrated using FIG.2 (c)-(e).

  First, as shown in FIG. 3 (a), other parts of the separation preventing tool 5 are not caught by the nut body 6 attached to the bolt body B, and the separation preventing tool 5 is set in the horizontal direction. The thread portion of the threaded portion 6f of the nut body 6 is in a positional relationship where it is inserted into the through hole 2 of the separation preventing tool 5, and is inserted as shown in FIG.

  Next, as shown by a white arrow in FIG. 3 (b), the separation preventing device 5 is placed horizontally while maintaining the insertion of the threaded portion of the screw portion 6f of the nut body and the through hole 2 of the separation preventing device 5. When it is rotated 90 degrees from the direction to the vertical direction, the state shown in FIG.

  Here, the relationship between the insertion part 1 of the separation prevention tool 5 and the through hole 2 will be described with reference to FIGS.

  As shown in FIG. 3A, the insertion portion 1 and the through hole 2 are parallel to each other, and the through hole 2 is longer than the opening end of the insertion portion 1, and in this state When the separation prevention tool 5 is translated in the horizontal direction, the threaded portion of the threaded portion 6f of the nut body 6 attached to the bolt body B is obstructed by other portions of the nut body 6 or the bolt body B. Without being inserted through the through hole 2.

  After that, the state shown in FIG. 3 (c) is obtained. Here, too, the threaded portion of the threaded portion 6f of the nut body 6 is inserted into the through-hole 2, and the adjacent portion 6c of the nut body 6 is fitted to face it. There is a gap between the opening end of the portion 1, and the proximity portion 5 c of the nut body 6 can be inserted to the bottom of the insertion portion 1 while maintaining the insertion state.

  In other words, the length of the through-hole 2 of the separation preventing tool 5 enables the attachment of the separation preventing tool 5 to the nut body 6 as described above.

  Now, in the state of FIG. 3 (c), when the separation prevention tool 5 is lowered downward in the figure, the locking groove 6 m of the proximity portion 6 c is inserted into the oblique opening 1 b of the fitting portion 1 while being guided. Furthermore, it is regulated by the narrow back portion 1a, and the close proximity portions 6c are as close as possible to each other or come into contact with each other, and the state shown in FIG.

  The oblique opening 1b has an opening width that changes in the extending direction of the through-hole 2 so as to change the degree of separation of the proximity portion 6c. As a result, as described above, the proximity portion 6c ( The locking groove 6m) is easy to fit. Moreover, the fitting state is more favorably maintained by the fitting between the locking groove 6m and the fitting portion 1.

  The proximity degree of the proximity portion 6c can be adjusted by adjusting the facing hole width of the narrow back portion 1a, and the nut body 6 is prevented from being opened by the narrow back portion 1a or is prevented from rotating. Is determined.

  Here, the term “open stopper” means that the proximity of the proximity portions 6c can be rotated while the nut body 6 is screw-engaged with the bolt body B to the same extent as a normal nut, while the proximity portion 6c. Is a function of preventing the nut body 6 from being released from being attached to the bolt body B.

  On the other hand, the non-rotating means that the proximity portions 6c are brought into full contact with each other, and the nut body 6 is screw-engaged with the bolt body B more firmly than a normal nut. The function which makes it the extent which does not turn even if the nut body 6 is rotated directly. Such a detent function cannot be exhibited by a normal nut alone.

  The nut body 6 of the present invention has a great feature that it can be attached from the side of the bolt body B as compared with a normal nut, and is combined with the separation preventing device 5 described here to prevent rotation by itself. It has the feature that it can have an effect.

  Note that the opening preventing function and the rotation preventing function of the insertion portion 1 are collectively referred to as a separation preventing function.

  When the proximity portion 6c of the nut body 6 is fitted into the insertion portion 1 of the separation preventing tool 5, as shown in FIGS. 4 (a) and 4 (b), the arrangement body H to be supported is separated. The lower side portion 5e is set to the lower side portion 5e of the support portion 3, and the lower side portion 5f is bent along the arrangement body H set at the bent groove 3a portion, as shown in FIG. If the threaded portion of the threaded portion 6f of the nut body 6 is fitted into the mounting hole 3b, and the nut N is screwed into this threaded portion, the support body H is fixed and fixed, and the nut of the separation preventing tool 5 is secured. The attachment to the body 6 is completed.

  In addition, this arrangement | positioning body HA illustrates the case of a ceiling support material.

  According to FIG. 4 (d) showing this state, in this example, the length of the lower side portion 5 e of the support portion 3 corresponds to the width of the arrangement body H, and in the height direction, Since the tip of the flange portion 5h provided in the portion 5g approaches or contacts the upper portion of the arrangement body H, the arrangement body H does not rattle the support portion 3 of the separation preventing device 5. Supported.

  Further, in this state, the separation preventing tool 5 not only supports the arrangement body H, but also the threaded portion of the threaded portion 6f of the nut body 6 is inserted into the through hole 2 and the mounting hole 3b, and is screwed. Therefore, the separation preventing tool 5 is not detached from the nut body 6, and therefore, the fitting state of the fitting portion 1 of the separation preventing tool 5 and the proximity portion 6 c of the nut body 6 is maintained well and reliably.

  That is, since the through hole 2 and the mounting hole 3b are fitted to the threaded portion of the threaded portion 6f of the nut body 6 at one location and both are screwed together with the nut N, the separation preventing device 5 is prevented from falling off and the support portion The arrangement body H supported by 3 can be fixed at a time, and there is no need for extra parts, and workability is good.

  Thus, according to the attachment body 10 (the separation prevention tool 5 and the nut body 6) of the present invention, the separation prevention tool 5 is held on the nut body 6 by passing the screw portion 5F through the through hole 2 and tightening the screw. Thus, the separation preventing tool 5 can be reliably prevented from falling off the nut body 6.

  When the support portion 3 is unnecessary, the contact wall 5d and the subsequent portions of the separation preventing tool 5 are removed so that the arrangement body H is not supported, and is inserted into the through hole 2 provided in the intermediate upper wall 5c. Even if the threaded portion 6f of the fitted nut body 6 is screwed, the separation preventing tool can be prevented from falling off.

  That is, even when the support portion 3 is not provided, a long through hole is necessary. In that case, the portion provided with the through hole serves as an anti-separation tool and exhibits the above effect.

  FIG. 5 shows another example of the separation preventing device constituting the attachment device of the present invention, in which (a) is a front view, (b) is a side view, (c) is a front view, and (d) is a front view. (E) is a cross-sectional view taken along the line AA in (d), (f) is a detailed view of the P part in (d), (g) is an external perspective view, and (h) is shown in (a) to (g). It is a figure which shows the support band used in combination with the separated separation tool.

  Compared to the separation prevention tool 5 of FIG. 1, the separation prevention tool 5A is not made of a rectangular plate of the same steel material that is continuously bent as a main part of the support part 3A, but is made of a separately manufactured steel. The difference is that the support band 3c (FIG. 5 (h)) is used.

  Accordingly, in the separation preventing tool 5 in FIG. 1, the contact prevention wall 5d, the lower side parts 5e, 5f, the upper step part 5g, the flange part 5h, and the like that constitute the support part 3 are not included in the separation prevention tool 5A. On the other hand, the other parts of the distal end lower portion 5a, the distal end lateral portion 5b, the intermediate upper wall 5c, and the fitting portion 1 are exactly the same as those in the separation preventing tool 5A.

  As for the through hole 2A provided in the separation preventing tool 5A, the screw part 6f (screw part) of the nut body 6 is passed through the through hole 2A as compared with the through hole 2 of the separation prevention tool 5 of FIG. By doing so, it is different in that it has a protrusion 2a that protrudes into the through hole 2A and regulates the movement of the screw portion 6f along the through hole 2A.

  Here, the part which comprises 5 A of this separation prevention tool 5A and the part which comprises 3 A of support parts of this separation prevention tool 5A with the support band 3c in the part different from the separation prevention tool 5 of FIG. 1 is demonstrated.

  The lower part of the intermediate upper wall 5c is a slanted wall portion 5j obtained by bending the same rectangular flat plate, a proximate wall 5k extending continuously near the slanted wall portion 5j and close to the bolt body B in the accommodated state, and the proximate wall 5k. The bent end 5m is provided only on both sides of the flat plate from the front end of the flat plate.

  The inclined wall portion 5j is provided with a rectangular band hole 5n for passing the support band 3c in the center thereof, and the support band 3c slips below the center of the width of the separation preventing tool 5A of the band hole 5n. Anti-slip protrusions 5p (see FIG. 5 (f)) are provided to prevent this.

  A square band hole 5o for passing the support band 3c is also provided in the center of the proximity wall 5k. The band hole 5o has the same width but a smaller length than the band hole 5n of the inclined wall portion 5j.

  The bent end 5m is bent from the adjacent wall 5k so that the inner corners thereof are in contact with the bolt body B in the accommodated state. The separation preventing tool 5A as a whole has both central axes with respect to the bolt body B. It guides so that it can be attached in a state of matching.

  As shown in FIG. 5 (e), the protrusion 2a provided in the through hole 2A is provided with notches parallel to both sides of the convex portion into the through hole 2A at an appropriate position of the long hole-like through hole 2A. The convex portion side to the through hole 2A is raised appropriately.

  The support band 3c is a band obtained by cutting a thin steel plate into a predetermined width and length, and a plurality of screw holes 3d for determining a tightening length are provided at appropriate positions.

  In this separation preventing tool 5A, the support portion 3A includes a slanted wall portion 5j, a proximity wall 5k, a bent end 5m, a support band 3c, and the like.

  6 (a) to 6 (e) are explanatory diagrams of an example of a usage method for attaching and using the attaching tool composed of the separation preventing tool of FIG. 5 and the nut body of FIG. 2 to the bolt body, Using these, how to use the separation preventing tool 5A and the attachment 10A including the same will be described.

  First, as shown in FIG. 6A, the support band 3c is set on the main body side of the separation preventing tool 5A. At this time, one end of the support band 3c is passed through the band hole 5n of the separation preventing tool 5A, folded back here, and brought into contact with the base side of the support band 3c through the smaller band hole 5o.

  At this time, the anti-slip protrusion 5p provided in the band hole 5n is caught in one of the screw holes 3d provided on one end side of the support band 3c, so that the band 3c does not slide any more.

  The subsequent processes in FIGS. 6A, 6B, and 6C are the same as those in FIGS. 3A to 3C and FIG.

  However, it should be noted that the nut body 6A has a longer threaded portion of the threaded portion 6f ′ than the nut body 6 of FIGS. 2 (a) and 2 (b). Also, the attachment of the nut body 6A to the bolt body B is omitted because it is the same as in FIGS. 2 (c) to 2 (d).

  When the attachment of the attachment body 10A composed of the nut body 6A and the separation preventing tool 5A to the bolt body B is completed, as shown in FIG. 6 (d), the spacer 3e is externally fitted to the screw portion of the nut body 6A. To do.

  Next, as shown in FIG. 6 (e), the arrangement body HA to be supported is wound by the support belt 3c, and the arrangement body HA is properly tightened in the screw hole 3d provided at the other end. When the screw hole 3d at a position where the screw can be supported is fitted into the screw portion of the nut body 6A and is screwed with the nut N, the support and fixing of the arrangement body HA is completed.

  In addition, this arrangement | positioning body HA illustrates the case of a wiring duct or a wiring cable.

  At this time, the raised protrusion 2a provided in the through hole 2A is simultaneously tightened with the nut N at the same time as the screw tightening, and the raised protrusion 2a is laid down on the same plane as the other part of the through hole 2A. It becomes a state.

  Accordingly, since the tip of the protrusion 2a protrudes toward the hole side of the through hole 2A, the screw portion 6 'of the nut body 6A can no longer move to the other part of the through hole 2A. Thus, the movement of the screw portion 6 'of the nut body 6A is restricted.

  As described above, the projection 2a functions as a positioning lock for the threaded portion 6 'of the nut body 6A inserted through the through hole 2A when screwed. In addition, such a protrusion 2a can be installed also in the through-hole 2 of the separation prevention tool 5 of FIG. 1, and exhibits the same effect.

  Thus, according to this attachment body 10A, the same basic effects as those of the attachment body 10 of FIGS. Furthermore, in this attachment body 10A, since the support portion 3A includes the long and short adjustable support bands 3c, the attachment body 10A can correspond to a wider variety of arrangement bodies.

  In this attachment body 10A, the inner diameter of the spacer 3e is such that the clearance fits into the threaded portion of the threaded portion 6 'of the nut body 6A so as not to easily fall off, and in the state of FIG. When the inner diameter of 3e is fitted into the threaded portion 6 'of the nut body 6A, the attachment body 10A is thereafter locked to the threaded portion 6' of the nut body 6A without falling off, and various subsequent operations can be performed by releasing it.
