DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher suspension apparatus for suspending a fire extinguisher, and which issues an alarm when the suspension is released.

[0002]

2. Description of the Related Art Fire extinguisher suspensions of this type generally have only a function of suspending a fire extinguisher, so that even when the suspended state is released, the fire extinguisher is susceptible to theft.

In view of the above, it has been proposed to attach a battery-operated alarm to the suspending device that issues an alarm when the suspended state of the fire extinguisher is released.

[0004]

In the above-mentioned conventional configuration,
It is necessary to periodically check the battery consumption and the like, and maintenance is troublesome. There is also a risk that the alarm will be mischief.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the present invention makes it possible to use a maintenance-free alarm that emits an alarm when the suspension of the fire extinguisher is released, and to prevent the alarm from being mischievous. It is intended to provide hanging equipment.

[0006]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The invention according to claim 1 is for suspending a fire extinguisher S. A helical spring type bell alarm 3 is provided on the hanging tool main body 2 provided with the hanging projection 8. The bell alarm 3 is depressed by a fire extinguisher S suspended on the hanging projection 8. And a lock lever 28 that is pushed up by removing the fire extinguisher S from the suspension projection 8 and is operable to activate the bell alarm 3 is concealed. The concealing cover 4 is configured to be detachably attached to the hanging tool main body 2.

In the above configuration, the fire extinguisher S is suspended from the suspension projection 8, the concealing cover 4 is detached from the suspension tool main body 2, and the helical spring of the bell alarm 3 is wound up. It is attached to the hanging tool main body 2.

In this state, the lock lever 28 is pushed down by the fire extinguisher S suspended on the suspension projection 8, and the bell alarm 3 is locked inoperable, so that the helical spring is not rewound. can do.

Further, since the bell alarm 3 is concealed by the concealing cover 4, the bell can be prevented from being removed due to mischief, and the bell alarm 3 can be removed by removing the concealing cover 4. The winding spring can be wound up.

Next, when the fire extinguisher S is removed from the suspending projection 8, the lock lever 28 is pushed up to activate the bell alarm 3 and an alarm is issued, so that the fire extinguisher S is stolen. There is little fear.

Further, since the bell alarm 3 is operated by a helical spring, there is no running out of the battery unlike the conventional case, and the bell alarm 3 can be used without any maintenance, and the management is not troublesome.

According to a second aspect of the present invention, in the first aspect of the invention, the engaging projections 33 are provided on both side surfaces of the suspension tool main body 2, and the engaging projections are provided on both side plates of the concealing cover 4. In this embodiment, an engagement hole 34 is formed to engage with the engagement hole 33 so as to be detachable.

According to the above structure, the concealing cover 4 is simply grasped and pushed out toward the hanging tool main body 2, so that the hanging tool main body 2
