It is provided on each of the direction one side and the other side.

  In addition, a fastener insertion hole 14 for a fastener 40 (FIG. 4) such as a screw, a nail, or a pin is formed in each of the hook portion 12 and the pair of contact protrusions 13R and 13L described above. Furthermore, the base part 11 of the hanging tool 10 includes a locking protrusion 15 protruding from the hook part 12 in the vertical direction Y1. The locking projection 15 is locked to the inner surface of the large hole 211b on the lower side in the vertical direction Y1.

  Next, a method for attaching the above-described hanging tool 10 to the attachment surface 30 will be described. First, in a state where the fastener 40 is inserted into the fastener insertion hole 14 of the suspension tool 10, the suspension tool 10 is pushed into the attachment surface 30 to attach the suspension tool 10 to the attachment surface 30. The three fastener insertion holes 14 are provided so that their penetration directions are different from each other, and the fasteners 40 respectively inserted into the fastener insertion holes 14 are pushed into the mounting surface 30 at different directions and angles. In this way, by using a plurality of fasteners 40 and pushing them into the mounting surface 30 at different directions and angles, the suspension tool 10 itself does not swing around the fasteners 40, and more The mounting surface 30 can be firmly attached. Therefore, the alarm device 20 is not tilted and suspended due to the suspension tool 10 swinging around the fastener 40.

  Next, a method for suspending the alarm device 20 on the hanging tool 10 attached to the attachment surface 30 will be described. First, the hooking protrusion 21 is inserted between the contact protrusion 13L and the contact protrusion 13R from the upper side of the vertical direction Y1 in a state where the lower side of the alarm device 20 in the vertical direction Y1 is tilted forward. Thereby, the horizontal direction Y2 of the alarm device 20 with respect to the hook part 12 can be positioned.

  Next, the suspension tool 10 is suspended in the large hole 211b formed in the hooking protrusion 21 while the alarm device 20 is slid vertically downward so that the hooking protrusion 21 is along the side surfaces 131R and 131L of the contact protrusions 13R and 13L. The hook portion 12 is inserted. Thereafter, when the alarm device 20 is further slid downward so that the hooking protrusion 21 is along the side surfaces 131R and 131L of the contact protrusions 13R and 13L, the hook part 12 is guided to the small hole 211a, and the hook part 12 is The small hole 211a can be hooked on the inner peripheral surface on the upper side in the vertical direction Y1.

  Thus, by providing the hooking hole 211 in a dharma shape, the hook part 12 can be easily inserted into the hooking hole 211 from the large hole 211b having a width W2 larger than the width Wf of the hook part 12. Then, after hook part 12 is hooked on the inner peripheral surface on the upper side in the vertical direction Y1 of small hole 211a, the vertical direction of large hole 211b is returned while returning the lower side of vertical direction Y1 of alarm device 20 tilted forward. The locking projection 15 is locked to the inner side surface below Y1, so that the hook 12 is not easily detached from the hooking hole 211, and the mounting is completed. By the locking with the locking protrusion 15 described above, the alarm device 20 can be positioned in the vertical direction Y1 with respect to the hook portion 12. The locking by the locking projection 15 can be easily released by tilting the lower side of the alarm device 20 in the vertical direction Y1 toward the front.

Since the movement of the alarm device 20 in the vertical direction Y1 is restricted by the hook portion 12 and the locking projection 15, the swing of the alarm device 20 around the hook portion 12 is also restricted. Therefore, even if a force that swings around the hook portion 12 is applied to the alarm device 20, the alarm device 20 does not tilt.

  Furthermore, in the present embodiment, the movement of the alarm device 20 in the horizontal direction Y2 can be restricted by the contact protrusions 13R and 13L, and the swing of the alarm device 20 can be restricted. Referring to FIG. 5 in detail, as shown in FIG. 5A, a force exceeding the restriction by the hook portion 12 and the locking projection 15 is applied, so that the alarm device 20 is horizontal with the hook portion 12 as the center. Even if it swings to the right side in the direction Y2, when the angle θ is inclined with respect to the original suspended position, the vertical direction Y1 upper side of the contact protrusion 13R and the lower side of the contact protrusion 13L in the vertical direction Y1 The hooking projection 21 of the alarm device 20 comes into contact, and the alarm device 20 does not swing more than this angle θ.

  Similarly, as shown in FIG. 5B, even if the alarm device 20 swings leftward in the horizontal direction Y2 with the hook portion 12 as the center, if the angle θ is inclined with respect to the original suspended position, the contact protrusion The hooking protrusion 21 of the alarm device 20 is in contact at two places, that is, the lower side of the vertical direction Y1 of 13R and the upper side of the vertical direction Y1 of the contact protrusion 13L, and the alarm device 20 does not swing more than this angle θ. . In this embodiment, the angle ± θ that is the swing range is made as small as possible so that the swing hardly occurs.

  For this reason, as explained in the background art, the center of gravity of the alarm device 20 is not on the symmetric line L1 or shifted from the symmetric line L1 due to the pair of abutting protrusions 13R and 13L and the locking protrusion 15. Even if the tension string 22 in the position is pulled and a force that swings around the hook portion 12 is applied to the alarm device 20, the alarm device 20 is not greatly inclined and suspended, thereby improving the aesthetics. Can be planned.

  Further, as shown in FIGS. 2 and 3, two fastener insertion holes 23 are formed below the alarm device 20 in the vertical direction Y <b> 1, and the alarm device 20 is directly attached to the attachment surface 30. ing.

In this way, by using the contact protrusions 13R and 13L as positioning protrusions, it is not necessary to provide the contact protrusions 13R and 13L and the positioning protrusions separately. Moreover, according to the hanging tool 10 mentioned above, the hook part 12 was provided between the contact protrusion 13R and the contact protrusion 13L. Thereby, the space between the contact protrusion 13R and the contact protrusion 13L can be effectively utilized, and the suspension tool 10 can be reduced in size.

  Moreover, according to the hanging tool 10 mentioned above, the vertical direction Y1 upper end part of the contact protrusions 13R and 13L is provided above the hook part 12 in the vertical direction Y1. Thus, before the hook portion 12 is caught by the hooking protrusion 21, the hooking protrusion 21 is inserted between the contact protrusion 13R and the contact protrusion 13L from the upper side in the vertical direction Y1, and the alarm device 20 is Positioning in the direction Y2 can be performed, and the installation work of the alarm device 20 becomes easy.

  Moreover, according to the hanging tool 10 mentioned above, side surface 131R, 131L by the side of the hook part 12 of contact protrusion 13R, 13L was formed in parallel with the perpendicular direction Y1. By the side surfaces 131R and 131L, the hook 12 can be hooked by guiding the alarm device 20 in the vertical direction Y1. In this way, by using the contact protrusions 13R and 13L as guide surfaces, it is not necessary to provide the contact protrusions 13R and 13L and the guide surfaces separately.

  Moreover, according to the hanging tool 10 mentioned above, the fastener insertion hole 14 was provided in the contact protrusion 13R, 13L. Thereby, the space of the contact protrusions 13 </ b> R and 13 </ b> L can be effectively utilized, and the hanging tool 10 can be reduced in size.

  Further, as shown in FIG. 7, the hook portion 12 of the suspension device 10, the contact projection portions 13 </ b> R and 13 </ b> L, and the hooking projection portion 21 of the alarm device 20 are sandwiched between the suspension device 10 and the base portion 11.

However, after hooking the hook portion 12 into the hooking hole 211, the hooking protrusion 21 is inserted between the contact protrusion 13R and the contact protrusion 13L to position the alarm device 20 in the horizontal direction Y2. Alternatively, the hooking protrusion 21 may not be inserted between the contact protrusion 13R and the contact protrusion 13L before the hook part 12 is hooked in the hooking hole 211.

  In the embodiment described above, as shown in FIG. 2B, the contact protrusions 13 </ b> R and 13 </ b> L are formed such that the height from the base 11 is lower than the hook 12. However, for example, it is also conceivable to form the contact protrusions 13R and 13L so that the height from the base 11 is higher than that of the hook portion 12. In this case, as described in the above-described embodiment, even if the upper end of the vertical direction Y1 of the contact protrusions 13R and 13L is not formed above the hook part 12 in the vertical direction Y1, the hook part 12 is hooked. Prior to being caught by 21, the hooking protrusion 21 can be inserted between the contact protrusion 13R and the contact protrusion 13L to position the alarm device 20 in the horizontal direction Y2. However, since the hook portion 12 is higher in height from the base portion 11 than the contact protrusions 13R and 13L, it is easier to perform the hooking operation.
