  First, in order to fix the fixing bracket 31 to the door D, the positions of the existing door-side mounting holes 21 and 22 are measured, and the fixing bracket-side mounting hole 32 for fastening the mounting screw 34 is determined.

  Specifically, as shown in FIG. 3, by placing one side where the fixing bracket mounting guide portion 11 is disposed on the upper surface of the door D, the door side disposed above the existing door side mounting holes 21 and 22. It is measured at which position of the mounting bracket 21 the mounting hole 21 exists. As shown in FIG. 3B, the fixing bracket mounting guide portion 11 includes three regions a, b, and c having a specific distance from one side of the mounting assisting tool 10, and the upper door. It is measured in which of the three regions a, b, and c the center of the side mounting hole 21 exists. For example, the door-side mounting hole 21 illustrated in the partial diagram (b) in FIG. 3 is located in the region a of the fixing bracket mounting guide portion 11. When the center of the upper door side mounting hole 21 is located on the boundary line between the regions a and b, the center is located in the lower region b, and the center of the upper door side mounting hole 21 is the region b and c. When located on the boundary line, it is assumed to be located in the lower region c.

  When it is measured in which position of the three regions a, b, and c of the fixing bracket mounting guide portion 11 the door side mounting hole 21 is present, as shown in FIG. The fixing bracket side mounting hole 32 for fastening the mounting screw 34 is determined from among the fixing bracket side mounting holes 32. More specifically, as illustrated in the partial diagram (a) in FIG. 4, when the upper door side mounting holes 21 are located in the region a of the fixing bracket mounting guide portion 11, two rows are formed in the fixing bracket 31. Of the six fixing bracket side mounting holes 32, the mounting screws 34 are fastened to the first fixing bracket side mounting holes 32 from the top and the third from the top of the left column. Further, as illustrated in the partial diagram (b) in FIG. 4, when the upper door side mounting hole 21 is located in the region b of the fixing bracket mounting guide portion 11, six rows formed in two rows on the fixing bracket 31 are formed. The mounting screws 34 are fastened to the two mounting bracket side mounting holes 32 formed in the right column among the mounting bracket side mounting holes 32. Furthermore, as illustrated in the partial diagram (c) in FIG. 4, when the upper door side mounting hole 21 is located in the region c of the fixing bracket mounting guide portion 11, six rows formed in two rows on the fixing bracket 31 are formed. Of the fixing bracket side mounting holes 32, the mounting screws 34 are fastened to the second row from the top and the fourth row from the top.

  Next, in order to fix the bracket 35 to the upper frame DH of the door D, the position of the existing upper frame side mounting hole 25 is measured and the bracket side mounting hole 36 for fastening the mounting screw 38 is determined.

  Specifically, as shown in FIG. 5, by attaching a side where the bracket mounting guide portion 13 is provided to the upper surface of the fixing bracket 31 fixed to the door D, the existing upper frame side mounting to the upper surface of the fixing bracket 31 is performed. The bracket side mounting hole 36 for fastening the mounting screw 38 is determined by measuring how much the hole 25 is visible from the side including the bracket mounting guide portion 13 having a specific length.

  As shown in the partial diagram (a) in FIG. 6, when the upper frame side mounting hole 25 is seen more than half from the side including the bracket mounting guide portion 13 of the mounting aid 10, it is formed on the bracket 35. Of the two bracket side mounting holes 36, the mounting screws 38 are fastened to the two bracket side mounting holes 36 formed on the upper side. Further, as shown in a partial diagram (b) in FIG. 6, when the ratio of the upper frame side mounting hole 25 visible from the side including the bracket mounting guide portion 13 of the mounting aid 10 is less than half, the bracket 35 The mounting screws 38 are fastened to the two bracket-side mounting holes 36 formed on the lower side of the four bracket-side mounting holes 36 formed on the bottom.

  In this way, the mounting screw 38 is fastened to the bracket side mounting hole 36 and the upper frame side mounting hole 25 determined by the mounting assisting tool 10 to fix the bracket 35 to the upper frame DH of the door D.

  Next, the slide mounting plate 41 is fixed to the fixing bracket 31. The fixture 31 is formed with a protrusion 33. As shown in a partial diagram (a) in FIG. 7, the protrusion 33 is inserted into a long hole 42 formed in the slide mounting plate 41. Then, as shown in FIG. 7B, the slide mounting plate 41 is slid in a state where the projection 33 is inserted into the long hole 42, and the extension of the center line of the bracket 35 and the slide mounting plate 41 are formed. The mounting mark 47 that is a mark when the slide mounting plate 41 is mounted is aligned. The slide mounting plate 41 arranged at the mounting position is fixed to the fixing bracket 31 by fastening a mounting screw 46 via a fixing plate 45 as shown in a partial diagram (c) in FIG.

  Then, the door closer body 51 is fixed to the slide mounting plate 41 fixed to the fixing bracket 31. As shown in FIG. 8, the door closer body 51 to which the arm link 61 is attached includes a pin 53 at the inner corner and a door closer body side attachment hole 54 at the side. The door closer body 51 locks the pin 53 to the locking portion 43 of the slide mounting plate 41, and the fixing hole 44 a formed in the fixing portion 44 of the slide mounting plate 41 and the door closer body side mounting hole 54. The mounting screw 55 is fastened and fixed to the slide mounting plate 41. The arm link 61 is connected to the bracket 35 by inserting the pin 37 of the bracket 35 into the bracket connecting portion 62.

  In the above, the usage method of the attachment aid 10 which concerns on this embodiment, and the attachment method of the door closer 100 were demonstrated. As described above, according to the attachment assisting tool 10 according to the present embodiment, the door closer 100 can be quickly and easily attached using the existing attachment holes.

  As mentioned above, although preferred embodiment of this invention was described, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the embodiment.

  For example, in the embodiment described above, the position of the door side mounting hole 21 above the door side mounting holes 21 and 22 is measured to determine the fixing bracket side mounting hole 32 for fastening the mounting screw 34. It is good also as determining the fixing metal side attachment hole 32 which measures the position of the door side attachment hole 22 of this, and fastens the attachment screw 34. As shown in FIG.

  It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
