DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher mounting body which is a stationary equipment for a fire extinguisher and has both functions of a fire alarm and a fire extinguisher burglar alarm.

[0002]

2. Description of the Related Art In addition to conventional fire extinguishers provided in homes and offices, fire extinguishers are often installed in passageways of apartment houses such as Mansion or in corners of general roads. There have been reports of accidents involving people or objects being injured by being thrown off the upper floors or being taken away secretly in time for an emergency.

[0003]

SUMMARY OF THE INVENTION The present invention prevents mischief and theft as described above,
An object of the present invention is to provide a fire extinguisher mounting body that can also function as a fire alarm when a fire extinguisher is removed.

[0004]

That is, according to the present invention, a rotating shaft penetrating a front plate and a rear plate arranged in parallel,
A main gear is fixed between the front plate and the rear plate, and a second gear fixed to a large gear fixed to an intermediate shaft including a first small gear meshing with the main gear, to a support shaft including a star gear. A hammer body to be hit with a bell supported by the rotating shaft on the front side of the front side plate is attached to a swinging shaft having a locking escapement claw that cooperates with the star gear, On the other hand, one end of a tension spring is fixed to a locking shaft that supports an outer end of a mainspring whose inner end is locked to an end of the rotating shaft protruding behind the rear side plate. The end is connected to a sliding plate that moves up and down along a frame body to which the rear side plate is fixed, and this sliding plate having a support for a fire extinguisher includes:
When the fire extinguisher is supported on the supporting portion, the weight of the fire extinguisher causes the sliding plate to move downward against the force of the tension spring, thereby suppressing the hammer body from hitting. An object of the present invention is to provide an alarm / fire extinguisher mounting body provided with a piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiment. 1 to 5 show a first embodiment of the present invention. FIG. 1 is an overall front view, FIG. 2 is a front view of FIG. 1 with a bell and a front side plate removed, and FIG. Is a side view of a main part showing a cross section of FIG. 4, and FIG. 4 is a rear view of the whole.

The front side plate 1 and the rear side plate 2 which are arranged in parallel
A screw 5 is engraved at the front end of the rotating shaft 4 which is connected by the connecting shaft 3 and penetrates the front side plate 1 and the rear side plate 2.

A bell 6 screwed and connected to the screw 5
In FIG. 2 showing a state in which the front side plate 1 is removed, a main gear 7 is fixed to the rotating shaft 4, and an intermediate shaft 9 having a first small gear 8 meshed with the main gear 7. The large gear 10 is fixed to.

The large gear 10 is meshed with a second small gear 13 fixed to a support shaft 12 having a star gear 11, and has a rocking escapement claw 14 cooperating with the star gear 11. A hammer body 16 to be hit the bell 6 is attached to the shaft 15. Note that the intermediate shaft 9, the support shaft 12, and the swing shaft 15 are all the front side plate 1
And the rear side plate 2 so as to be rotatable.

On the other hand, as shown in FIG. 5, a pin 1 is provided on the side surface of the end of the rotating shaft 4 projecting behind the rear side plate 2.
7, a pin 17 is engaged with a small hole 19 provided at the inner end of the mainspring 18, and an eye hole 20 formed at the outer end of the mainspring 18 is implanted in the rear side plate 2. The lock shaft 21 is supported.

The frame 22 to which the rear side plate 2 is fixed has an appropriate mounting portion 23 formed thereon, and a sliding plate 24 which can move up and down along the frame 22 is supported.
4 is connected to the other end of a tension spring 25 whose one end is connected to the locking shaft 21.

An eye piece 27 protruding from an intermediate portion of a fire extinguisher 26
At the upper end of the sliding plate 24 formed at the lower end with the supporting portion 28 for hooking the eye piece 27, the weight of the fire extinguisher 26 is applied to the sliding plate 24 by hooking the eye piece 27 on the supporting portion 28. When the sliding plate 24 slides downward against the force of the tension spring 25, the sliding plate 24 is hooked on the support shaft 29 of the hammer body 16 to prevent the movement of the hammer body 16. Deterrent piece 30
Is provided.

When the bell 6 is gripped and turned while the eyepiece 27 of the fire extinguisher 26 is hooked on the support portion 28 of the mounting body of the present invention having the above-described structure, the rotation shaft 4 As the spring rotates, the mainspring 18 is rolled up. At this time, since the weight of the fire extinguisher 26 is applied, the sliding plate 24 is rotated.
Of the locking escape claw 14 is engaged with the support shaft 29 of the hammer body 16.
Meshes with the teeth of the star gear 11 to prevent the rotation of the star gear 11, so that the main gear 7
Is also prevented.

In the state where the mainspring 18 is sufficiently wound as described above, the fire extinguisher 26 is
8, the slide plate 24 is raised by the action of the tension spring 25, and the restraining piece 30 releases the support shaft 29 of the hammer body 16, so that the rotating shaft 4 rotates until the mainspring 18 is unwound. And the gear train, ie, the main gear 7, the first
The small gear 8, the large gear 10, and the star gear 11 rotate, and the hammer body 16 repeatedly strikes the bell 6 by the swinging of the locking escapement claw 14, thereby generating a continuous alarm. .

FIG. 6 shows a second embodiment in which most of the mechanisms are the same as in the first embodiment, but in this embodiment, in order to make the holding of the fire extinguisher more secure to the mounting body, The frame 22 in the first embodiment is replaced with a large frame 31, and the tightening band 3 for fastening the body of the fire extinguisher 26 to the frame 31.
2 and a receiving body 34 having a hook 33 for receiving the lower edge of the fire extinguisher 26. The receiving body 34 is slid up and down in order to fit large and small fire extinguishers. It is possible, and another tension spring 34 is erected.

[0015]

According to the present invention, it is possible to prevent the fire extinguisher from being removed from the installation location or being removed by mischief, and to remove the fire extinguisher from the mounting body of the present invention when a fire occurs. Thus, an effect of being able to play a role as a fire alarm at the same time is produced.
