Description

  The present invention relates to a hanging fitting, and more particularly to an improvement of a hanging fitting using a long bolt.

  When attaching a metal fitting to a long bolt, the metal fitting is generally fixed with a nut sandwiched between them, and the nut holding the metal fitting is rotated. For example, in Patent Document 1 below, the beam member is fixed by the coupling member, but both nuts sandwiching the beam member are rotated.

  FIG. 1B shows an example of the background art. In this example, a metal fitting 20 is hooked on a channel 12 extending from the ceiling 10, and long bolts 26 are fixed to the metal fitting 20 by nuts 22 and 24. An object 30 such as a lighting fixture is suspended from the lower end of the long bolt 26 and is fixed to the lower end of the long bolt 26 by nuts 32 and 34.

  In this case, the nut 22 is turned from the upper end side of the long bolt 26 to a predetermined position, while the nut 24 is turned up from the lower end side of the long bolt 26 so that the metal fitting 20 is sandwiched. By changing the position where the nuts 22 and 24 of the long bolt 26 sandwich the metal fitting 20, the position where the object 30 is suspended from the ceiling 10 can be changed.

Japanese Utility Model Publication No. 7-6320

  In the background art described above, the worker works while facing the ceiling direction, but in order to rotate the nut 24 with respect to the long bolt 26 and bring it to a desired position, the worker is in a supine state facing the ceiling. As a result, workability is poor and fatigue is accumulated.

  The present invention pays attention to the above points, and its purpose is to fix the metal fitting in a desired position in a short time with respect to the long bolt and to improve the work efficiency.

  The present invention is a hanging metal fitting on which a hanger is fixed to a long bolt, which has a through hole through which the long bolt penetrates, and which can be smoothly moved along the long bolt. A first inner screw that is screwed to the long bolt and a different-diameter nut having a second inner screw that is screwed to the bolt with the through hole. The hanger is positioned and fixed to the long bolt by screwing with a diameter nut.

  According to one of the main forms, the hanger includes a hook for suspending a hanging metal fitting, a bolt with a through hole, and a fixing piece sandwiched between the different diameter nuts. According to another aspect, a nut for screwing the long bolt to fix the object is provided at the lower end of the long bolt. The above and other objects, features, and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

  According to the present invention, since a nut with a different diameter and a bolt with a through hole are combined, the metal fitting can be fixed in a desired position in a short time with respect to the long bolt, and work efficiency can be improved. it can.

(A) is a figure which shows the structure of the hanging metal fitting of one Example of this invention, (B) is a figure which shows background art.

  Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.

  FIG. 1 shows an example of the present invention, and a hanging metal fitting 100 is constituted by a hanger 110 and a bolt and nut mechanism 120. The hanger 110 is bent at one end in a hook shape, hooked to a channel 12 extending from the ceiling 10, and the other end is bent in a substantially L shape, and is fixed to the bolt and nut mechanism 120. The fixed piece 114 is provided. The bolt and nut mechanism 120 includes a long bolt 122 that penetrates the fixed piece 114 of the hanger 110, a different diameter nut 130 that is screwed to the long bolt 122 from above, and a screw that is screwed to the long bolt 122 from below. And a bolt 140 with a hole. An object 30 such as a lighting fixture is fixed to the lower end of the long bolt 122 by nuts 32 and 34.

  Among the above portions, the different diameter nut 130 includes a first inner screw 132 that is screwed to the long bolt 122 and a second inner screw 134 that is screwed to the bolt 140 with the through hole. The inner diameter of the second inner screw 134 is set larger than the inner diameter of the long bolt 122 or the first inner screw 132. On the other hand, the bolt 140 with a through hole is provided with a through hole 142 having an inner diameter larger than the outer diameter of the long bolt 122 so that the long bolt 122 can smoothly move through the through hole 142. An external screw 144 is formed on the outer side of the bolt 140 with the through hole, and the external screw 144 is screwed with the second internal screw 134 of the different diameter nut 130 described above.

  Next, the operation of this embodiment will be described. The worker first hooks the hook 112 of the hanger 110 on the channel 12. Next, the different diameter nut 130 of the long bolt 122 that passes through the fixed piece 114 of the hanger 110 is rotated to position the long bolt 122. When the position of the fixing piece 114 with respect to the long bolt 122 is known in advance, the hook 112 of the hanger 110 may be hooked on the channel 12 after setting the different diameter nut 130 to the corresponding position. Good.

  Next, the operator shifts the bolt 140 with the through hole above the long bolt 122 and screws the external screw 144 into the second internal screw 134 of the different diameter nut 130. At this time, according to the present embodiment, since the long bolt 122 passes through the through hole 142 of the through hole bolt 140, the operation of shifting the through hole bolt 140 upward can be quickly performed. By screwing and tightening the through hole bolt 140 to the different diameter nut 130, the fixing piece 114 of the hanger 110 is sandwiched and fixed by the different diameter nut 130 and the through hole bolt 140. Thereafter, the operator hangs and fixes an object such as a lighting fixture to the lower end of the long bolt 122 fixed as described above using the nuts 32 and 34.

  As described above, according to this embodiment, since the different diameter nut 130 and the through hole bolt 140 are combined, the hanger 110 can be fixed to the long bolt 26 in a short time. Work efficiency can be improved.

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) The shapes and dimensions shown in the above embodiments are examples, and may be appropriately changed as necessary. In particular, various types of hangers 110 are known.
(2) In addition to the usage shown in the figure, it is possible to use the hanger 110 upside down or sideways. The directions of the different diameter nut 130 and the through hole bolt 140 are also the same.
(3) Although the hanger 110 is hooked on the channel 12 in the above embodiment, the object to be hooked is arbitrary, and various objects may be hooked.
(4) The present invention can be applied even when one end of the long bolt is screwed into a nut embedded in the ceiling.
(5) If necessary, a washer and a spring washer may be provided between the fixed piece 114 of the hanger 110, the different diameter nut 130, and the bolt 140 with the through hole.

  According to the present invention, the metal fitting can be fixed to a desired position with respect to the long bolt in a short time, and work efficiency can be improved, which is suitable for fixing the hanging metal fitting to the ceiling.
