Description

[Detailed Description of the Invention] This invention relates to an improvement of a fire extinguisher that is activated by turning a lever and spews out extinguishing agent, such as small fire extinguishers installed in general homes, buildings, etc.

The structure and operation of a fire extinguisher activated by rotation of a lever will be briefly explained with reference to FIG. 1, which shows an embodiment of the present invention. A cylinder (not shown) filled with pressurized gas is attached to the bottom surface of the lid 3 which is attached to the upper opening of the container 1 filled with extinguishing agent with a cap nut 2.
is fixed, and a firing pin 4 with a sharpened lower end is housed in the lid 3 above the cylinder so as to be freely slidable in the vertical direction. Furthermore, a fixed handle 5 is provided on the top of the lid 3, and an activation lever 7 that is rotatable about a shaft 6 at one end above the handle 5. The upper end of the firing pin 4 is locked to a locking portion 8 between hanging walls 7a, 7a formed on both sides of the activation lever 7. When using a fire extinguisher, rotate the starting lever 7 about the shaft 6 and press down. This lever 7 will push down the firing pin 4, and its sharp lower end will break the seal of the cylinder. , the pressurized gas in the cylinder blows out into the container 1. Therefore, the extinguishing agent in the container 1 is pushed by this pressure gas, ascends a siphon pipe (not shown) provided in the container 1, and is ejected from a nozzle at the tip of the hose 9.

By the way, in a fire extinguisher that is configured and operates as described above, when the fire extinguisher is not in use, the activation lever 7 rotates due to the extinguisher falling over or an object falling onto the activation lever 7, causing the extinguishing agent to be released. A mechanism is provided to prevent inadvertent spouting. That is,
When the fire extinguisher is not in use, the lever 10, whose lower end is pivotally attached to the upper surface of the handle 5, is raised as shown in FIG. 12 straight portions 12a are made to protrude toward the rear surface (right side in FIG. 1) of the tilting rod 10. Therefore, even if you try to push down the activation lever 7 in this state, the bottom surface of this lever 7 will touch the activation lever 1.
0, the activation lever 7 cannot be pushed down, and the extinguishing agent will not be inadvertently spouted out. When using the fire extinguisher, pull out the safety pin 12 upward and push down the activation lever 7. The upper end surface 10a of the tilting rod 10 is an inclined surface,
As the activation lever 7 is rotated downward, a force is applied to rotate the lever 10 clockwise in FIG. This lifting rod 10 is arrow a
It can automatically fall in the direction and activate the fire extinguisher.

The fire extinguisher of the present invention utilizes the lever 10 which is pushed against the lower surface of the activation lever 7 during use to allow the user to immediately recognize the fact that the fire extinguisher's safety pin has been pulled out. It is something. That is, a standing wall-shaped display section is provided on the front surface of the tilting rod 10 (left side surface in FIG. 1), which is hidden by the hanging walls 7a, 7a of the starting lever 7 when the tilting rod 10 is in the upright state. An appropriate display indicating that the safety pin 12 has been pulled out and the safety device is in a non-functional state is attached to the machine, and if this display section is visually observed with the tilting rod 10 fallen down, the fact that the safety pin 12 has been pulled out can be known. This prevents the fire extinguisher from being accidentally activated by leaving the fire extinguisher with its safety device removed.

Hereinafter, the present invention will be explained in more detail with reference to drawings showing embodiments.

Lifting rod 1 used in the fire extinguisher safety device of the present invention
0, as shown in FIG. 2, a vertical wall-shaped display section 13 is formed on the front surface 10b. This display section 1
3 is surrounded by the lower surface of the starting lever 7, the inner surfaces of the left and right hanging walls 7a, and the upper surface of the locking part 8 when the raising lever 10 is erected in the state shown in FIG. It is formed into a trapezoidal shape as shown in the figure, so that it can freely enter into the space where the starting lever 7 is pushed down, and as long as it does not collide with the lower surface of the lever 7 when the actuating lever 7 is pushed down. This display section 1
On both sides of 3, write letters or other symbols such as ``Requires Inspection'' or ``Reinspection'' that will make it clear at a glance that the fire extinguisher's safety pin has been removed. In addition, in Figure 2,
Reference numeral 14 denotes a circular hole provided in the left-right direction at the lower end of the lever 10 for inserting a shaft 15 (FIGS. 1, 3, and 4) for pivotally mounting the lever 10 on the upper surface of the handle 5;
is the straight part 1 of the safety pin 12 when the lifting rod 10 is raised.
This is a groove formed on the rear surface of the lever 10 in order to prevent the safety pin 12 from rattling when the safety pin 2a is inserted. The upper end surface 10a of the tilting rod 10 is an inclined surface as in the conventional case, so that when the activation lever 7 is pressed down, a force is applied in the direction of tilting the tilting rod 10.

The raising rod 10 formed as described above has the first,
As shown in Figures 3 and 4, the shaft 1 inserted into the circular hole 14
5 is pivotally attached to the upper surface of the handle 5. The lever 10 pivotally attached to the upper surface of the handle 5 is normally erected as shown by solid lines in FIGS. 1, 3, and 4, and is inserted into the through hole 11 of the trigger lever 7 from above. A safety pin 12 prevents it from falling. In this state, the display section 13 on the front surface 10b of the lever 10 is displayed on the lower surface of the starting lever 7 and on the hanging walls 7a, 7.
It enters the space surrounded by the inner surface of a and the upper surface of the locking part 8, and cannot be visually recognized from the outside. When the safety pin 12 is pulled out to use the fire extinguisher or as a result of mischief, the lever 10 rotates around the shaft 15 as described above, as shown by the chain line in FIGS. 1 and 4. It falls onto the top surface of the handle 5. In this state, the display section 13 on the front surface 10b of the lever 10 is exposed above the handle 5 and can be easily seen from the side. Therefore, by providing an appropriate display on the display unit 13, it is possible to easily know that the fire extinguisher has been operated.

In order to ensure that the tilting rod 10 falls down, a suitable spring may be provided between the handle 5 and the tilting rod 10 to give elasticity to the tilting rod 10 in the direction of always falling.

Furthermore, the shape of the safety pin 12 may be formed into a number 9 shape as shown in FIG. 5, or a T shape as shown in FIG. 6, or an L shape (not shown). It can also be formed into a letter shape. in this case,
The display section 13 is formed at the center of the front surface of the tilting rod 10, and is also formed at the front surface 10b, avoiding the loop section of the safety pin 12.
