Description

[Detailed Description of the Invention] The present invention relates to a usability determination device for a fire extinguisher that can clearly determine whether the fire extinguisher is used or not.

Conventionally, this type of identification device has been proposed, for example, in a previous application (Utility Model Publication No. 57-1961). When a usable identification indicator with an insertion shaft formed on the top is inserted and the movable lever is operated downward, the insertion shaft is cut and the usable identification indicator falls down, and this time the used identification indicator is removed. It is disclosed that the body is exposed. However, with these types of fire extinguishers, a display indicating whether or not the fire extinguisher can be used is attached to the side of the fire extinguisher.
Depending on the direction in which the fire extinguisher was installed, it could not be seen at all, making it impossible to check when it was immediately transported to the scene of a fire. Moreover, if you carry the fire extinguisher without being able to check this, you will have to look at the display on the side of the fire extinguisher midway through the fire, as it is usually carried with the fixed and movable levers held in your hands and positioned below your waist. This resulted in the inconvenience of having to carry the fire extinguisher to the fire scene without knowing how it was used.

In addition, since the usability determination device has a structure in which the insertion shaft of the usability determination indicator is cut at the lower end of the side tip of the movable lever, the usability determination indicator must be made to protrude considerably from the side surface of the fixed lever. Furthermore, if the inner thickness of the usable indicator itself is taken into consideration, foreign objects will be more likely to hit the usable indicator, and if a foreign object hits, the insertion shaft will easily break. This resulted in the inconvenience of using a used fire extinguisher even if it was a usable one. Also, once this insertion shaft breaks,
Generally, the usable indicator, which is made of synthetic resin, has to be replaced with a new one, which has the disadvantage of being quite expensive.

Furthermore, in the discriminating device of the earlier application, the insertion shaft of the usable discrimination indicator is pushed into the hole of the fixed lever and inserted into one side of the fixed lever; After drilling the lever, the entire lever is painted to prevent rust, so it is impossible to make the hole diameter constant, which makes it difficult to insert the insertion shaft of the usable identification indicator, and it is difficult to do so. As a device for determining whether a fire extinguisher can be used, the device may break the insertion shaft by pushing it in, or the hole diameter may be too large to securely fix it, or in worse cases, the usability indicator may fall off. Finally, there was a problem that seemed to be lacking.

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a device for determining whether or not a fire extinguisher can be used, which can eliminate all of the above-mentioned inconveniences and problems.

In order to achieve the above object, the present invention provides a fire extinguisher in which extinguishing agent is ejected by rotating a movable lever on the lid that can be rotated up and down around the tip end downward. A projection opening is formed in the upper surface of the movable lever facing the lid, and the projection opening is positioned between the projection opening and the lid and on the lid, and when the movable lever is rotated downward, the projection opening is A used identification indicator is provided, the upper part of which protrudes from the inside, and an engaging part formed on the side thereof is engaged with the edge of the ejection opening and is followed upwardly together with the movable lever.

Embodiments of the present invention will be described below with reference to the drawings.

1 in the figure is a fire extinguisher. In this fire extinguisher 1, a fixed lever 3 is fixed to a lid 6, and a movable lever 2 on the lid 6 is rotatably connected to the upper end of the fixed lever 3 via a shaft 9. The movable lever 2 can be rotated up and down around the
When the fixed lever 3 is grasped by hand, the movable lever 2 is operated downward, and at the same time, the destruction shaft 4 linked to the movable lever 2 is pushed downward, and the gas cylinder (not shown) in the fire extinguisher container 5 is released. The sealing plate is broken, thereby filling the fire extinguisher container 5 with high-pressure gas from the gas cylinder, and the extinguishing agent in the fire extinguisher container 5 is transferred to a nozzle (not shown) attached to the tip of the hose 20.
It is beginning to be ejected from the outside world. In addition,
Reference numeral 7 denotes an operation blocking piece for preventing the movable lever 2 from unexpectedly rotating downward when the fire extinguisher 1 is not in use. The actuation blocking piece 7 is rotatably attached to both side walls of the fixed lever 3 and is held in an upright state by supporting the upper end with an actuation blocking piece fixing device A. When in use, the movable lever 2 can be moved downward by removing the operation blocking piece fixing device A.

By the way, in such a fire extinguisher 1, the usability determining device, which is a feature of the present invention, is as follows.

That is, the used discrimination display body 10, which constitutes the main body of the usability discrimination device, is made of a synthetic resin plate, and is disposed between the movable lever 2 and the lid body 6, and has the movable lever at its tip. 2 and the fixed lever 3 are rotatably fitted onto the shaft 9, and the bottom surface of the support portion 10a matches the upper recess 6a of the lid 6 of the fire extinguisher 1. A shaped contact portion 10b is formed.

Further, the upper surface of this used identification display body is attached to a movable lever when the support portion 10a and the contact portion 10b are fitted and positioned in the pivot shaft 9 and the upper surface recess 6a of the lid body 6, respectively. 2 (specifically, the movable lever 2
It is formed so as to be flush with the upper end edge of the protrusion opening 2b for the used discrimination display body 10 formed in the upper surface 2a. Further, on the rear side of the used identification display body 10, there is a cut groove 10c having a required length in the vertical direction, an elastic piece on the rear side of the cut groove 10c, and an arrow-shaped upper end of the elastic piece. An engaging portion 10d is formed, and the circumferential surface of the protruding opening 2b of the movable lever 2 is brought into contact with the outer circumferential surface of the engaging portion 10d, and the movable lever 2 is moved downwardly as shown in FIG. When the engaging portion 10d is actuated to the side, the outer peripheral surface of the engaging portion 10d is moved into the kerf 10 by the peripheral surface of the protruding opening 2b of the movable lever 2.
It is pressed and biased towards the c side, and the upper part of the used identification display body 10 is configured to project upwardly due to the rebound effect of this pressure bias.
Further, the used discrimination display body 10 that has been operated to protrude upward from the upper surface 2a of the movable lever 2
the engaging portion 10 so as to be followed upwardly.
A locking portion 10e that locks onto the edge of the ejection opening 2b is provided on the lower surface of d, and an indication ``used'' is written on one side of the protruding used identification indicator 10.

Therefore, when the movable lever 2 is operated downward, the used identification display body 10 is moved to its support portion 10.
a is rotatably supported by the pivot shaft 9,
In addition, since the abutting portion 10b is located in the upper surface recess 6a of the lid body 6, the used identification indicator 10 is moved upwardly from the upper surface 2a of the movable lever 2, as shown in FIGS. 3 and 4. At the same time, the used identification display body 10 is rebounded by the engaging portion 10d, causing it to be pushed upward with a jerk. This protruded used identification indicator 1
0 is locked to the edge of the protruding opening 2b of the movable lever 2 by the locking part 10e formed on the lower surface of the engaging part 10d (see FIG. 5), so that the locking part 10d is The joint 10d is connected to the protrusion 2 of the movable lever 2.
The used identification indicator 10 always maintains its protruding state unless it is inserted into the indicator b.

In addition, on the upper surface of the used identification indicator 10, a usable indicator 11 with "usable" written on the surface is attached to both sides of the movable lever 2, and when the used indicator 10 is pushed out, If the user does so, the center portion of the usable display body 11 will be broken.

As is clear from the above description, in the present invention, the used identification indicator protrudes from the upper surface of the movable lever when the movable lever is operated downward. The used identification indicator does not protrude, and therefore the display function of the used identification indicator can be performed with sufficient reliability.

In addition, with the used identification indicator of the present invention, it is possible to determine whether or not the fire extinguisher can be used based on whether or not the used identification indicator protrudes upward from the upper surface of the movable lever. It can be accurately determined from anywhere regardless of the situation. Moreover, even if a used fire extinguisher 1 is carried to a fire scene, the usability indicator of the present invention can be confirmed by the state protruding from above the movable lever without reading the text, making it easier to carry it. This can be easily noticed during the process, and it is possible to effectively prevent a situation in which it is only when the fire extinguisher is activated that one realizes that it is a used fire extinguisher 1.

In addition, the used identification indicator of the present invention is very easy to operate since it is only necessary to move the movable lever downward in order to expose the used identification indicator.
