Description

This invention relates to a connector that includes a flange nut that screws onto a hanging bolt, such as a turnbuckle or anti-vibration hanging fitting (anti-vibration support hanging piping fitting), and a frame that fixes the body of the flange nut protruding from a horizontal upper plate and the connection object that connects to the hanging bolt to a downward-facing lower plate.

The above-mentioned connector will be described with reference to FIG. 9, taking the "Tanbuckle" (Non-Patent Document 1, etc.) as an example.
A turnbuckle 80 shown in FIG. 9 is a connector for connecting a suspension bolt 96 suspended from a slab 95 or the like to a connection target (not shown) such as a suspension band.

The turnbuckle 80 comprises a flange nut 81 and a frame 85. The flange nut 81 consists of a body 82 and a flange 83. The frame 85 has an insertion hole 87 into a horizontal upper plate 86 into which the body 82 of the flange nut 81 is inserted, and a pair of downward-facing lower plates 89, 89 have bolt holes 90, 90 for fixing a suspension band or the like, and protrusions 91, 91 are often provided to prevent the flange nut 81 from falling off during transportation, etc.

In the turnbuckle 80 having the above structure, the flange nut 81 is inserted (screwed) onto the suspension bolt 96. The flange nut 81 is rotated to adjust the insertion length into the suspension bolt 96 (to adjust the level of the piping supported by a suspension band not shown).
A flange portion 83 of the flange nut 81 , which has a diameter larger than that of the insertion hole 87 , contacts the upper plate 86 to support the frame 85 .

However, the conventional turn buckle 80 has the following problems as shown in FIG.
(1) As shown in FIG. 10( a ), when frame 85 is held and brought close to the tip of hanging bolt 96 during insertion of hanging bolt 96, support of flange portion 83 by protrusions 91, 91 is unstable, causing flange nut 81 to rattle and the surface that screws into hanging bolt 96 not facing straight up, making it difficult to insert hanging bolt 96.
(2) As shown in Figure 10(b), when the flange nut 81 is rotated, the body 82 does not protrude much from the insertion hole 87, making it difficult to grip the body 82 (general flange nuts are used as a nut + washer and are not designed to be inserted into a hole like a turn buckle), and the frame 85 also gets in the way, making it difficult to grip. In particular, poor operability is noticeable when the turn buckle 80 is above the eye level of the worker.
(3) As shown in FIG. 10(c), after installation, there is play between the flange nut 81 and the frame 85, so that vibrations of the supported piping, etc. cause rattling noises.

The applicant therefore conducted extensive testing and research to resolve the above-mentioned issues with conventional connectors such as the turn buckle 80, and to provide the connector with ease of installation and stability after installation, and thus completed the present invention.

The first invention of the present application is a rotating member for a connector comprising a flange nut that screws onto a hanging suspension bolt, and a frame that protrudes the body of the flange nut from a horizontal upper plate and fixes an object to be connected to the hanging bolt to a downward lower plate, the rotating member being attached to the body of the flange nut and rotating in conjunction with the body while expanding the body.
A second aspect of the present invention is a rotating member for a connector, wherein the rotating member is attached above the upper plate.
A third aspect of the present invention is a rotating member for a connector, wherein the rotating member protrudes in a width direction of the upper plate.
A fourth aspect of the present invention is a rotating member for a connector, wherein the rotating member extends upward beyond the upper tip of the body portion.
A fifth aspect of the present invention is a rotating member for a connector, characterized in that the rotating member and the upper plate abut or are capable of abutting against each other.
A sixth aspect of the present invention is a rotating member for a connector, wherein the rotating member is attached by being pressed against the outer periphery of the body portion.
A seventh aspect of the present invention is a rotating member for a connector, wherein the rotating member is attached so as to be insertable from a side surface of the body portion.
An eighth aspect of the present invention is a rotating member for a connector, wherein the rotating member has a guide mechanism for inserting a hanging bolt.
A ninth aspect of the present invention is a connector comprising a connector rotating member according to any one of the first to eighth aspects of the present invention.

The present invention as described above has the following advantages.
(1) In the rotating member for connectors according to the present invention, the underside of the rotating member and the upper plate of the turn buckle (frame) are flush with each other, and the surface of the flange nut that stably screws into the suspension bolt faces straight up, dramatically improving the ease of installation when inserting the connector (body of the flange nut) into the suspension bolt.
(2) Furthermore, by attaching the rotating member to the body of the flange nut, the body is enlarged (horizontally and/or vertically), making it easier to rotate the flange nut and dramatically improving the ease of installation when inserting the connector (the body of the flange nut) into the hanging bolt.
(3) Furthermore, the rotating member regulates the vibration of the flange nut, reducing rattling and dramatically improving stability after installation.

An embodiment (example) of the present invention will be described with reference to the drawings. Note that the illustrated embodiment is an example of the present invention, and the present invention is not limited to these.

1 and 2 are explanatory diagrams showing a connector rotating member 10 according to a first embodiment.
As shown in Fig. 1, a rotating member for connectors (hereinafter referred to as "rotating member") 10 is used by being attached to a turnbuckle 80, which is a connector. In Fig. 1, a suspension band 97 that supports a pipe is fixed to a lower plate 89 of a frame 85 via bolts and nuts 92.
The rotating member 10 is a cylindrical member having a knurled outer peripheral surface 11, and is provided at its center with a mounting hole 12 for mounting to the body 82 of the flange nut 81. Note that the outer peripheral surface 11 is not limited to a knurled shape, and may have an uneven structure having an anti-slip effect.

FIG. 2 illustrates how the rotating member 10 is attached to the body portion 82 .
2A, the body 82 of the flange nut 81 is inserted into the mounting hole 12 of the rotating member 10. At this stage, the flange nut 81 is semi-fixed to the frame 85.
2B, the rotating member 10 is inserted until the flange portion 83 of the flange nut 81 abuts against the lower surface of the upper plate 86, completing the attachment of the rotating member 10. At this stage, the flange nut 81 is completely fixed to the frame 85 (the rotating member 10 and the flange nut 81 are integrated with each other by sandwiching the upper plate 86).

When the flange nut 81 is completely fixed to the frame 85, the tip surface of the body 82 that screws into the suspension bolt faces straight up, making it extremely easy to screw the turnbuckle 80 (body 82 of the flange nut 81) into the suspension bolt during installation.

In addition, the body 82, which was difficult to grasp because it protruded little from the insertion hole 87 and was in the way due to the frame 85, is expanded by the rotating member 10 and rotates in conjunction with it, so there is no need to operate the body 82 by simply operating the rotating member 10, which is easy to grasp, and the work of screwing the turn buckle 80 (body 82 of the flange nut 81) onto the hanging bolt during installation becomes extremely easy.

Furthermore, the flange nut 81 is completely fixed to the frame 85 (the rotating member 10 and the flange nut 81 are integrated by sandwiching the upper plate 86), so the flange nut 81 does not rattle after being installed on the hanging bolt, and the installation state of the turn buckle 80 is extremely stable.

In addition, because the diameter of the body 82 is larger, torque can be easily applied when turning the knob with your fingers, making it extremely easy to adjust the level after piping is installed.

FIG. 3 (FIGS. 3-1 and 3-2) is an explanatory diagram showing a connector rotating member 10A according to a second embodiment.
As shown in FIG. 3A, the rotating member 10A-1 has an expanded diameter so as to protrude from the upper plate 86.
This prevents the frame 85 (upper plate 86) from becoming an obstacle when rotating the rotating member 10A-1, facilitating the operation of screwing the body 82 onto the hanging bolt.
3-2, the rotating member 10A-2 may have a part of its outer periphery protruding from the upper plate 86. This is because even if only a part of the outer periphery protrudes, the operation of screwing the body part 82 to the suspension bolt becomes easier.

FIG. 4 is an explanatory diagram showing a connector rotating member 10B according to the third embodiment.
As shown in FIG. 4, the rotating member 10B is narrower than the width of the upper plate 86 but longer than the body portion 82.
This prevents the frame 85 from becoming an obstacle when rotating the rotating member 10A, and makes it easier to screw the body 82 onto the hanging bolt.
The second and third embodiments may be combined to form a rotating member 10 having an increased diameter and a long body.

FIG. 5 is an explanatory diagram showing a connector rotating member 10C according to a fourth embodiment.
5, the bottom surface of the rotating member 10C is flat, which allows it to come into close contact with the upper plate 86. This allows the flange nut 81 to be securely and completely fixed to the frame 85.

FIG. 6 is an explanatory diagram showing a connector rotating member 10D according to the fifth embodiment.
6, the rotating member 10D is an elastic body having a mounting hole 12 with an inner diameter smaller than the outer diameter of the body 82, and is attached by pressing the mounting hole 12 against the body 82. This prevents the rotating member 10D from falling off the body 82. In addition, because the rotating member 10D holds the flange nut 81 by an elastic body, the protrusions 91, 91 of the turn buckle 80 are not necessary.
In addition, since it is sufficient that the rotating member 10D and the body portion 82 are able to rotate in conjunction with each other, the rotating member 10D is attached by abutting (including pressing) against the outer periphery of the body portion 82.

FIG. 7 (FIGS. 7-1 and 7-2) is an explanatory diagram showing a connector rotating member 10E according to a sixth embodiment.
7-1, the rotating member 10E-1 has a C-shape with a notch so that it can be inserted (attached) from the side of the body 82. This allows the rotating member 10E to be attached to or detached from the body 82 after the turn buckle 80 is attached to the hanging bolt 96.
7-2, the rotating member 10E-2 has a structure in which divided parts are fitted together so that it can be inserted (attached) from the side of the body 82. This allows the rotating member 10E to be attached to or detached from the body 82 later.

FIG. 8 is an explanatory diagram showing a connector rotating member 10F according to the seventh embodiment.
As shown in FIG. 8-1, the rotating member 10F has a guide mechanism 13 for inserting the hanging bolt 96.

The guide mechanism 13 will be further described in detail with reference to FIG.
As shown in FIG. 8-2(a), the hanging bolt 96 is guided into the mounting hole 12 by the inclination 14 formed on the upper surface of the rotating member 10F.
As shown in FIG. 8-2(b), the R-shape 15 formed on the inner wall of the mounting hole 12 guides the hanging bolt 96 so that it faces vertically.
As shown in FIG. 8-2( c ), by providing several contact points 16 on the inner wall of the mounting hole 12 that come into contact with the hanging bolt 96 , the vertical state is maintained, making it easier to insert the hanging bolt 96 into the body 82 .

The present invention can be used by attaching it to a connector that includes a flange nut that screws onto a hanging bolt, such as a turnbuckle or anti-vibration hanging fitting (anti-vibration support hanging piping fitting), and a frame that allows the body of the flange nut to protrude from a horizontal upper plate and fixes the connection target that is connected to the hanging bolt to a downward-facing lower plate.
