Description

  TECHNICAL FIELD The present invention is used to extinguish fires such as tempura oil and wastebaskets at home, and relates to a household fire extinguishing apparatus represented by an aerosol-type simple fire extinguisher.

The conventional fire extinguishing apparatus of this type is well known in its structure and operation, as is apparent from, for example, the aerosol-type simple fire extinguishing apparatus disclosed in Japanese Patent Application Laid-Open No. 4-28379. To do.
JP-A-4-28379

  The problem to be solved is that the button (9) is protected by a cap (10) so that the button (9) is not accidentally pressed and a transparent resin is used for safety so that the cap (10) is not inadvertently removed. When you use (release), remove the transparent resin and remove the cap (10). When removing the cap (10), it is difficult to remove the transparent resin that is tightly attached. Because it is difficult, it is difficult to use it for those with low acupressure and grip strength, such as the elderly, and those who can use only one hand, and it is too time-consuming to operate in an emergency, and the release of the fire extinguishing agent is delayed, making it an early fire extinguisher. It is a point that does not become.

  The present invention includes a fire extinguisher release mechanism comprising a mechanism frame fixed to a base of a fire extinguisher storage container, and a discharge pipe inserted into the mechanism frame so as to be able to descend, and the discharge pipe is pushed down. The lower end of the discharge pipe pushes open the valve part of the extinguishing agent storage container so that the extinguishing agent is discharged from the front end of the discharge pipe, and the upper push button part swings back and forth with the lower part as a fulcrum. The lock member is slidably inserted into the mechanism frame so as to move, and in a normal locked state, the receiving bar of the lock member engages with the convex portion of the discharge tube to lower the discharge tube. And when the lock is released when the push button portion is pushed in, the lock member swings so that the receiving bar is detached from the convex portion so that the discharge pipe can be lowered (lock release state). Features.

  The present invention can be used only by pushing the push button part protruding from the mechanism frame of the fire extinguishing agent release mechanism, or the person who can use only one hand, such as elderly people who cannot push the push button part, such as elderly people. Then, you can release the safety lock of the discharge tube by the lock member just by striking the push button part against your elbow, knee, wall or desk, and so on. Even those who can use only one hand can easily release the safety lock and use it easily. In an emergency, the safety lock can be released quickly and the initial fire can be extinguished.

  A fire extinguishing agent release mechanism is provided inside the mechanism frame, and a lock member for locking the fire extinguisher release mechanism is provided in the mechanism frame so that the lock member can be easily unlocked simply by pushing the push button portion. It was realized by doing.

  An embodiment of the present invention will be described with reference to FIGS. 1 is a longitudinal side view showing a normal state, FIG. 2 is a longitudinal side view showing a state where the lock is released from FIG. 1, FIG. 3 is a longitudinal side view showing a state radiating from FIG. 2, and FIG. It is the figure seen from the front.

  In the figure, 1 is a fire extinguishing agent storage container such as an aerosol can, 2 is a valve shaft (part) from which the fire extinguishing agent is ejected by projecting and pushing into the base 1a of the fire extinguishing agent storage container 1, and 3 is a base of the fire extinguishing agent storage container 1 A mechanism frame body 4 including a base portion 3 a fixed to 1 a and an arch frame portion 3 b erected on the base portion 3 a is provided at the center of the base portion 3 a of the mechanism frame body 3 to cover the valve shaft (portion) 2. The vertical cylinder 5 is inserted into the mechanism frame 3 so as to be able to swing back and forth, and the lower end 6 is inserted into the vertical cylinder 4 and the front end 7 is prevented from clogging the mechanism frame 3. An inverted L-shaped discharge tube comprising a horizontal tube portion 5b abutting against the cover portion 8, 9 is a spring that always pushes down the discharge tube 5 in the vertical direction, and 10 is a lower portion 10a behind the discharge tube 5 in the mechanism frame 3. The upper push button is inserted so that the upper part swings back and forth with the fulcrum as the fulcrum 10b is a locking member that protrudes from the rear surface of the mechanism frame 3, 11 is a receiving bar that is provided on the locking member 10 to receive the convex portion 12 of the discharge pipe 5 from below, and 13 is provided on the inner surface of the mechanism frame 3. A claw for holding the front surface of the lock member 10 from the front, and 14 swings forward and backward with the upper part (not shown) as a fulcrum in front of the discharge pipe 5 in the mechanism frame 3, that is, inside the L-shape of the discharge pipe 5. The discharge lever 15 is inserted in such a manner that a drive unit 15 has a cam surface 15a projecting on the rear surface of the discharge lever 14 and for pushing down the vertical tube portion 5a of the discharge tube 5, and 16 is a vertical tube portion of the discharge tube 5. A driven member provided on 5a and driven by the cam surface 15a of the drive unit 15 and descending along the guide 17, 18 is a protrusion provided on the lower surface of the release lever 14, and is provided in the hole of the base 3a of the mechanism frame 3. Lock to make up the lever lock state It has become.

  In the normal state shown in FIG. 1, the upper end of the front surface of the lock member 10 is engaged with the claw 13 and the lock member 10 is fixed to the arch frame portion 3 b, so that the convex portion 12 of the discharge pipe 5 is the receiving bar 11. The release lever 14 is not lowered because the drive unit 15 is prevented from swinging backward (gripping direction) by the driven member 16. In other words, in this state, the discharge tube 5 and the release lever 14 are solidified by the lock member 10 and are held in a state where the release lever 14 cannot be operated.

  In the unlocked state shown in FIG. 2, when the push button portion 10 b of the lock member 10 is pushed in and the front upper end of the lock member 10 is released from the claw 13 and swings forward, the receiving bar 11 is moved away from the convex portion 12. Since it is detached, the discharge pipe 5 is slightly lowered by the force of the spring 9 and its lower end 6 is on the valve shaft (part) 2. That is, in this state, the release lever 14 can be operated at any time.

  3 and 4, when the discharge lever 14 is grasped and the driven member 16, that is, the discharge pipe 5 is pushed down by the cam surface 15a, the valve shaft (part) 2 is moved at the lower end port 6 thereof. Since it is pushed open, the fire extinguisher in the fire extinguisher storage container 1 radiates through the discharge pipe 5 from its tip end 7.

  At the time of use, in the normal state shown in FIG. 1, when the push button portion 10b is pushed in the direction of the arrow 19, when the upper end of the front surface of the lock member 10 is pushed away from the claw 13, the lock shown in FIG. Since it is in a released state and can be radiated at any time, if the release lever 14 is grasped thereafter, the fire extinguishing agent is radiated from the front end opening 7 as shown in FIGS.

  The operation of pushing the push button portion 10b is not only a normal operation of holding the fire extinguisher storage container 1 with one hand and pushing the push button portion 10b with the other finger, but it is not possible to push the push button portion 10b. Thus, for those who have little finger pressure and grip strength or who can use only one hand, the lock member 10 can be safely locked by simply pushing the push button portion 10b against its elbow, knee, wall or desk. Because it can be released, it is easy to use and easy to use even for those with low acupressure, grip strength and those who can use only one hand, such as elderly people. You can cancel the initial fire extinguishing.
