Description

The present invention relates to a mounting bracket for mounting a fire alarm for a house or the like on a wall surface.

  Conventional fire alarms for homes are used by attaching to a wall such as a gypsum board in a room that monitors fire, so a dedicated fixing plate is fixed to the wall with a set pin for gypsum board. An alarm device is attached to (Patent Document 1).

Also, using a dedicated fixing plate takes time to install and increases the cost as much as the fixing plate is required. Therefore, a hook hole was provided in the alarm, and a screw was fixed to the wall and fixed. A method of attaching an alarm by inserting a hook hole in a screw is also used, so that the installation is simple and the cost burden can be reduced.

  However, in the method of attaching the alarm device using such a hook hole, there is an advantage that the attachment is easy and the cost can be reduced, but the hook hole is hung on a mounting bracket with a screw or a hook. Therefore, if the alarm device moves upward when an inspection operation or the like for confirming the operation of the alarm device is performed, the hook hole may easily come off from the screw or the hook and fall. Also, because it was installed on the wall of the room, there was a risk that the hook hole would come off the screw or hook and fall if the alarm moved by knocking during cleaning.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hook-fitting mounting bracket that does not come off even if an alarm moves due to inspection operation or cleaning.

In order to achieve this object, the present invention is configured as follows. The present invention provides a mounting bracket for hooking an alarm device having a hook hole to a wall surface, with a plate-shaped bracket body, a hook projecting forward from the bracket body, and lower corners on both sides of the bracket body. A pair of retaining portions formed so as to be bent in an oblique direction and restrict the upward movement of the alarm device in a mounting state where the hook hole of the alarm device is hung on the hook ,
A pin insertion hole for inserting a stop pin formed in each of the retaining portions is provided.

Here, the pin insertion hole formed in each of the retaining portions is formed in a direction in which the retaining pin is oriented so that the retaining pin opens obliquely downward with respect to the wall surface on which the metal fitting body is attached. Further, a positioning pin insertion hole may be formed in the flat portion of the metal fitting body.

  According to the present invention, since the mounting bracket has a pair of retaining portions bent in the front diagonal direction at the lower corners on both sides, the alarm device moves upward in a mounting state where the hook hole of the alarm device is hung on the hook. However, it is possible to reliably prevent the hook hole from coming off the hook by restricting the upward movement when the upper end of the alarm device hits the retaining portion of the mounting bracket.

  In addition, the mounting bracket has a pin insertion hole formed in the retaining part bent in the front diagonal direction at the lower corners on both sides, so that the direction of the pin insertion hole is an oblique downward direction that spreads outward with respect to the wall surface. Even if it exists, sufficient attachment strength can be ensured.

  In addition, since the pin insertion hole is also formed in the flat part of the bracket body, if you want to further secure the mounting strength, in addition to the pin insertion hole in the retaining part, However, the mounting strength can be easily secured by inserting the stop pin.

Further, since a pin insertion hole for positioning is formed in the flat part of the metal fitting body, the attachment position of the metal fitting can be determined with the pin lightly inserted into the pin insertion hole.

FIG. 1 is an explanatory view of a mounting state of a fire alarm using the mounting bracket of the present invention. In FIG. 1, a fire alarm 10 for a house is composed of a main body 11b and a cover 11a, protrudes from the front upper part of the cover 11a to form a smoke inlet 14, and has a built-in scattered light type smoke detection mechanism therein. Yes.

  An acoustic hole 16 is formed below the smoke inlet 14, and a speaker for outputting an alarm message is built therein. Further, the inspection operation unit 18 is pulled out below, and when the inspection operation unit 18 is pulled for a certain period of time, an alarm message for confirming the operation is output, and when an alarm is output when a fire is detected, the inspection operation unit 18 is output. The alarm output can be stopped by pulling continuously.

  A mounting portion 20 is provided on the upper portion of the main body 11 b of the fire alarm 10. A hook hole 22 is formed in the attachment portion 20. The hook hole 22 forms a longitudinal hole upward following the lower circular hole.

  The fire alarm 10 can be attached to the wall surface by the mounting bracket 12 of the present invention. The mounting bracket 12 is integrally formed with a hook 26 in front of the bracket body, and further, a lower corner portion on both sides of the bracket body is bent obliquely forward to form a retaining portion 28, and a pin insertion hole is formed in the retaining portion 28. 30 is formed, and the mounting bracket 12 is fixed to the wall surface through the pin insertion hole 30 with a fixing pin. Further, a pin insertion hole 30 is formed in the flat portion of the mounting bracket 12.

  The fire alarm 10 is attached to the mounting bracket 12 by fitting the hook hole 22 formed in the mounting portion 20 at the top of the fire alarm 10 into the hook 26 of the mounting bracket 12 of the present invention attached to the wall surface. ing.

  FIG. 2 is a side view of FIG. 1, and shows a state in which the pin is inserted into the wall surface in cross section. In FIG. 2, the mounting bracket 12 is made of a plaster board or the like through a pin insertion hole 30 provided in a retaining portion 28 that is bent at the lower corners on both sides of the bracket main body 24 and protruded obliquely forward. The wall surface 36 is driven and fixed.

  Since the hook 26 is positioned in front of the metal fitting body 24 in this state, the hook 26 can be attached to the wall surface 36 by fitting the hook hole 22 (see FIG. 1) of the fire alarm device 10 into the hook 26.

  FIG. 3 is an explanatory view of a mounting bracket according to the present invention, FIG. 3 (A) is a plan view, FIG. 3 (B) is a front view, FIG. 3 (C) is a bottom view, and FIG. Further, FIG. 3E shows a perspective view.

  In FIG. 3, the metal fitting body 24 of the present invention has a substantially hanger-like shape when viewed from the front, and is opened upward at the center of the front portion to integrally form a hook 26. Further, the lower corner portions on both sides of the metal fitting body 24 are bent in a diagonally forward direction to form a retaining portion 28. A pin insertion hole 30 is formed in the retaining portion 28. Further, a pin insertion hole 32 is formed in a flat portion of the metal fitting body 24.

  The pin insertion direction 38 of the pin insertion hole 30 formed in the retaining portion 28 is a pin insertion hole orthogonal to the surface of the retaining portion 28 because the retaining portion 28 is bent obliquely forward with respect to the flat surface of the metal fitting body 24. The pin insertion direction 38 is determined by drilling 30 holes, and the pin insertion direction 38 is diagonally downward spreading outward with respect to the wall surface to which the mounting bracket 12 is attached. As a result, the stop pin 34 is driven into the pin insertion hole 30 as shown in FIG. At this time, it can be reliably fixed with sufficient supporting strength to the wall surface 36 using a plaster board or the like.

  Further, since the pin insertion direction 38 is a direction extending downward and outward with respect to the two pin insertion holes 30, it has sufficient rigidity with respect to the downward weight when the fire alarm 10 is suspended from the hook 26. Can be supported.

  Furthermore, since the pin insertion holes 32 for positioning are formed in two places in the flat part of the metal fitting body 24, the attachment position of the metal fitting body 12 can also be determined. By driving the pin in a state where the position is formally determined, the mounting strength can be further increased by supporting the mounting bracket 12 with a total of four retaining pins.

  Next, the operation of the retaining portion 28 provided on the metal fitting body 24 of the present invention will be described. When the hook hole of the fire alarm device 10 is mounted using the mounting bracket 12 shown in FIG. 2 and the hook hole 22 (see FIG. 1) of the fire alarm device 10 is inserted into the hook 26 of the mounting bracket 12, The fire alarm 10 is fixed in a suspended state along the line 36.

At this time, the wall surface 36 side of the upper part of the main body 11b of the fire alarm 10 is located below the retaining portion 28 bent to the front surface of the mounting bracket 12, so that the fire alarm 10 moves upward in the mounted state. even per upper portion of the main body 11b within unplug stop portion 2 8 mounting member 12, more, without moving upwards, whereby it is possible to regulate the hook hole 22 from the hook 26 comes off .

  For this reason, for example, when the inspection operation unit 18 is pulled for a certain period of time for an inspection to perform an alarm operation in the attached state, even if the fire alarm device 10 is displaced upward, it does not come off the hook 26. . Further, when the fire alarm device 10 is hung up when cleaning the room, even if the fire alarm device 10 moves upward, the fire alarm device 10 can be reliably prevented from falling off the hook 26.

  The present invention is not limited to the shape of the mounting bracket 12 shown in the above-described embodiment, and a retaining portion 28 that has a hook 26 and is bent in a diagonally forward direction at both lower corner portions is formed. As long as the insertion hole 30 is opened, an appropriate metal fitting shape can be formed.

Moreover, although said embodiment took a fire alarm device as an example, it is not limited to this, For the appropriate alarm device or apparatus used by attaching to a wall surface, the mounting bracket of this invention can be applied as it is. it can.
