As the alarm device K of the present invention, for example, various commonly used wall-mounted alarm devices K such as a gas alarm device, a fire alarm device, or an air contamination alarm device are applicable. The alarm device K includes an alarm device body 4 that incorporates various sensor mechanisms according to applications, such as a city gas detection sensor, a carbon monoxide sensor, or a temperature sensor / smoke sensor. The alarm device body 4 is composed of a front side member 4a facing the room side and a back side member 4b facing the wall 1 side. The front side member 4a is provided with an LED 6 and a buzzer 7 for informing alarm contents, an inspection operation button 8, and the like, in addition to the detection unit 5 through which the detection target gas can flow.
On the other hand, a first case member 9 around which the power cord 3 is wound, a second case member 10 covering the power cord 3 and the like can be attached to the back member 4b.

(First case member)
The 1st case member 9 is attached to the back side member 4b of the said alarm device main body 4, and forms the accommodating part 11 which winds and accommodates the power cord 3 in the space between the said back side member 4b. As shown in FIG. 8, the first case member 9 is provided with two openings, a first opening 12 and a second opening 13. On the other hand, as shown in FIGS. 4 and 5, three claw portions 14 are erected on the back member 4b. Among these, the two claw portions 14 are engaged with the peripheral edge of the first opening portion 12 provided on the upper side of the alarm device body 4. One claw portion 14 is engaged with the peripheral edge of the second opening portion 13 provided on the lower side of the alarm device body 4. Thereby, as shown in FIG. 6, the 1st case member 9 can be attached to the back side member 4b.

  In addition, although illustration is abbreviate | omitted, you may provide the said 1st opening part 12 and the said 2nd opening part 13 in the 2nd case mentioned later. In short, any configuration may be used as long as the hook member 2 is attached to any member constituting the back surface of the alarm device.

  Inside the first case member 9, as shown in FIG. 8B, a reel portion 15 that serves as a core member when the power cable is wound is provided. The reel portions 15 are distributed in the periphery of the first opening 12 and the periphery of the second opening 13. This reel part 15 determines the space | interval of both members at the time of attaching the 1st case member 9 to the said back side member 4b.

  A winding mode of the power cord 3 is shown in FIG. That is, the power cord 3 taken out from the corner of the back side member 4 b passes through the inside of the groove 16 provided in the back side member 4 b and is hooked on the latching portion 17 that is formed to protrude inside the first case member 9. Thereafter, the power cord 3 is wound around the reel portion 15. The power cord 3 having a length necessary for the attachment of the alarm device K is left and wound, and the power cord 3 is inserted into a slit 18 provided at a corner of the first case member 9. As shown in FIG. 6, the first case member 9 has a flange portion 19 that holds the wound power cord 3 so as not to collapse. With these configurations, the power cord 3 can be efficiently adjusted to a predetermined length.

  On the outer surface of the first case member 9, as shown in FIGS. 8A and 8B, a recess 20 is formed across the first opening 12 and the second opening 13. When the first case member 9 is attached to the hook member 2 due to the concave portion 20, the hook member 2 is buried in the first case member 9, and the surfaces of the two members are flush with each other.

  At this time, as shown in FIG. 2, the hook member 2 is arranged inside the three claw portions 14. The three claw portions 14 engage outwardly with the inner edge portions of the first opening portion 12 and the second opening portion 13. When the hook member 2 is disposed inside these claw portions 14, the side surface of the claw portion 14 and the side surface of the hook member 2 are substantially in contact with each other or are in close proximity. As a result, the hook member 2 has a function of preventing disengagement of the claw portions 14 engaged with the respective openings. With this configuration, after attaching the alarm device K to the wall 1, even when some external force is applied to the alarm device K, the claw portion 14 is unlikely to be detached from the first case member 9. Therefore, the alarm device K can be more reliably attached.

(Second case member)
After the power cord 3 is wound around the first case member 9, the second case member 10 is further attached to the alarm device body 4. As shown in FIGS. 4 and 5, the attachment mechanism engages the latching portion 22 provided at the corresponding position of the second case member 10 with the latched portion 21 provided on the side portion of the alarm device body 4. . Thereby, the power cord 3 can be covered and the design of the alarm device K can be enhanced.

  The second case member 10 is provided with an opening 23 that matches the outer shape of the first case member 9. Further, as shown in FIG. 5, a stepped portion 10 a is provided on the inner surface side of the opening portion 23 in order to improve adhesion with the edge portion of the first case member 9. Thereby, a clearance gap does not arise between the 1st case member 9 and the 2nd case member 10, and the surface of the back side of the alarm device K will be in a flush state with a sense of unity. With this configuration, the design of the back side of the alarm device K is improved, and further, no gap is formed between the wall 1 to be attached, so that small insects or the like can be prevented from entering the alarm device K. it can.

(Hook member)
The alarm device K is attached by a dedicated hook member 2. A state in which the hook member 2 is attached to the first case member 9 is shown in FIG. Thus, when the hook member 2 is attached, the inner peripheral edge portion of the concave portion 20 and the outer peripheral edge portion of the hook member 2 coincide with each other, and the surface of the hook member 2 is opposed to the back surface of the alarm device K. It is configured to be flush with each other. That is, the back surface of the alarm device K constituted by the first case member 9, the second case member 10, and the hook member 2 is a flat surface. In this way, the surface of the back side of the alarm device K is almost completely covered, so that small insects can be completely prevented from entering the inside of the alarm device K.

  Details of the hook member 2 are shown in FIG. FIG. 7 (a) is a view of the hook member 2 seen from the inside of the alarm device K, FIG. 7 (b) is a view seen from the side, and FIG. 7 (c) is a view of the wall 1. It is the figure seen from the side.

  The hook member 2 is attached to the wall 1 by a fixing member 24 such as a wood screw 24a as shown in FIG. For this purpose, a hole (hereinafter referred to as a first hole 25) through which the fixing member 24 can pass is provided. The first hole 25 is a simple through-hole, but as shown in FIGS. 7 (a) and 7 (b), a step 26 for burying the head of the wood screw 24a is formed.

  Furthermore, the hook member 2 can be engaged with the first opening 12 and the recess 20 by sliding in one direction across the first hole 25 in a direction substantially parallel to the plane of the first case 9. A first locking portion 27 is provided. The upper end portion of the first locking portion 27 includes a tapered portion 28 so that the first locking portion 27 can be easily locked to the first opening 12 of the first case member 9. The first locking portion 27 is provided with a restriction surface 29 as shown in FIGS. Thereby, the latching position of the 1st latching | locking part 27 with respect to the 1st opening part 12 is determined. Due to this locking, the first locking portion 27 bears most of the weight of the alarm device K.

  On the other hand, a second locking portion 30 is provided on the side opposite to the first locking portion 27 across the first hole portion 25. The second locking portion 30 is provided at the end of the hook member 2 and has a shape protruding toward the inside of the alarm device K. Here, the second locking portion 30 only locks in a direction substantially perpendicular to the outer surface of the first case member 9. However, since the second locking portion 30 has a protrusion having a predetermined length toward the inside of the alarm device K, the engagement with the second opening 13 is ensured.

  As described above, by providing the first locking portion 27 and the second locking portion 30 at substantially both ends of the hook member 2, the distance between the first locking portion 27 and the second locking portion 30 is as much as possible. It can be secured for a long time. Therefore, the rotation of the first case member 9 with respect to the hook member 2 can be minimized, and the attachment of the alarm device K to the wall 1 becomes more reliable.

  As shown in FIGS. 5 and 7, the hook member 2 includes a second hole portion 31 into which a fixing member different from the fixing member 24 such as the wood screw 24 a can be inserted. The hook member 2 may be rotated only by inserting the wood screw 24a or the like into the first hole. For example, as shown in FIGS. 1 to 3, an inspection button 8 is provided on the front surface of the alarm device body 4, and when the alarm device K is attached to a high place in the room, the button 8 is provided. In order to facilitate the operation, an operation string 32 is attached to the lower part of the button 8. Since the operation string 32 can be pulled in any direction, the alarm device K may be rotated if the hook member 2 is loosely attached to the wall 1. Therefore, as in the present configuration, the second hole 31 is provided at a location different from the first hole 25.

  For example, as shown in FIG. 7, the second hole portion 31 is provided at a position close to the second locking portion 30. The longer the distance from the first hole 25 is secured, the higher the effect of preventing the hook member 2 from rotating. For example, a thin nail member 24b24b, which is another fixing member 24, is inserted into the second hole portion 31. Further, the insertion direction of the nail member 24b is set so as not to be perpendicular to the direction connecting the first hole portion 25 and the second hole portion 31. Thereby, when a force to rotate the hook member 2 is applied, the insertion direction of the nail member 24b and the rotation direction of the second hole 31 are different, so that the nail member 24b is difficult to be removed, and the hook member against the wall 1 The attachment of 2 can be strengthened.

  In addition, as shown in FIG. 7, two second hole portions 31 are also provided in the vicinity of the first hole portion 25. The insertion direction of these second holes 31 is also set to an angle that is not perpendicular to the line connecting the first hole 25 and the second hole 31 as shown in FIGS. is there.

  Further, any of the nail members 24b is not perpendicular to the wall 1, but has a predetermined inclination angle. With this configuration, even if an external force is applied in a direction in which the hook member 2 is separated from the wall 1, the direction in which the hook member 2 attempts to separate is different from the driving direction of the nail member 24b. For this reason, the nail member 24b is hard to come off, and the hook member 2 can be firmly fixed to the wall 1.

  The head of the nail member 24b protrudes and remains on the surface of the hook member 2. However, the two second hole portions 31 provided in the vicinity of the first hole portion 25 are opened in the chamfered portion 33 formed in the first locking portion 27. Further, as shown in FIG. 8, the hole portion of the latching portion 17 on which the power cord 3 is hooked faces the second hole portion 31 provided in the vicinity of the second locking portion 30. Therefore, the head of each nail member 24b does not interfere with other objects.

  The present invention can be applied to various commonly used wall-mounted alarm devices such as a gas alarm device, a fire alarm device, and an air contamination alarm device.
