JP2011206087A - Automatic falling fire-extinguishing grenade - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an automatic falling fire-extinguishing grenade to be set on an indoor ceiling or wall of a building such as a house, capable of being automatically and quickly operated when a fire occurs while no resident is present or while residents are sleeping at night; and to provide the inexpensive automatic falling fire-extinguishing grenade capable of being easily set, capable of being easily introduced into a building regardless of the type of the building and capable of being easily handled.SOLUTION: The fire-extinguishing grenade includes a fire-extinguishing agent sealed in a shock-rupturing container, and is set on a ceiling or wall by optionally selected hanging means hung from the indoor ceiling or wall of the building. The rise of temperature caused by fire deprives the hanging means of its holding function, and the fire-extinguishing grenade falls. As a result, the container ruptures and the fire-extinguishing agent is dispersed, so that the fire is extinguished.

Description

  The present invention relates to an automatic drop-type fire extinguisher that is installed on an indoor ceiling or wall of a building such as a house or a building and operates quickly at the time of a fire.

Initial fire extinguishing is most important in building fires, but the built-in fire extinguisher is often not useful because it cannot be operated correctly in a panic. On the other hand, there is a throw-type fire extinguisher that throws out the fire and extinguishes it. In this fire extinguisher, a fire extinguishing agent made of an aqueous solution of ammonium chloride-sodium carbonate or the like is enclosed in an impact rupturable container such as a glass ampoule or a resin container that is easily broken. The fire is scattered and extinguished (see Patent Document 1).

  In addition, facilities that allow unspecified number of people to enter and exit are required to have automatic fire extinguishing equipment, and these buildings have sprinklers installed on the indoor ceiling. This automatic fire extinguishing system detects a fire, opens a valve, sprinkles water from a sprinkler piped in an elevated water tank, and extinguishes fire (see Patent Document 2).

  Fire extinguishing bombs are convenient to handle, but do not help fire when people are away or at night. Automatic fire extinguishing equipment is large and involves expensive equipment construction, is expensive to introduce into a small-scale facility, and is totally unsuitable for private housing.

  The present invention is intended to solve these problems, and is installed on the ceiling or wall of a building such as a house or a building so that it can automatically and quickly catch fire when a person is away or at night. The aim is to propose an automatic drop-type fire bomb that operates and is capable of reliable initial fire fighting. It is also an object of the present invention to propose an automatic dropping fire bomb that is easy to install and inexpensive, can be easily introduced regardless of the type of building, and is excellent in handling.

  In order to achieve the above object, the automatic drop-type fire bomb of the present invention is provided with a ceiling or wall by any hanging means for suspending a fire bomb in which an extinguishing agent is enclosed in an impact-ruptureable container from the indoor ceiling or wall of the building. The suspension means loses its holding function due to temperature rise in the event of a fire, the fire bomb falls, the container bursts, and the fire extinguishing agent is scattered to extinguish the fire.

  In addition, the fire bomb is dropped by melting the thread that suspends the fire bomb. is there.

  Moreover, an arbitrary design is given to a fire extinguisher and it commercializes as an interior product.

  The automatic drop-type fire extinguishing bullet of the present invention is installed on the ceiling or wall by any hanging means suspended from the indoor ceiling or wall of the building, and the hanging means loses its holding function due to the temperature rise at the time of fire, Since the bullets fall and extinguish, they operate automatically and quickly when a person is away or during a nighttime sleep, and a reliable initial fire extinguishing is possible. Further, since no special construction is required, the installation is simple and the cost is low, it can be easily introduced regardless of the type of building such as a small-scale facility, a restaurant, or a house.

  In addition, since the control does not depend on the power source, it operates reliably even in the event of a power failure such as an earthquake, does not require special maintenance such as battery replacement, is excellent in handling, and accommodates care recipients who are particularly difficult to evacuate. It is useful to install in elderly facilities.

The drawing is an embodiment of the present invention and is an explanatory diagram of a state where it is installed on the ceiling. Explanatory drawing of a fall state. Explanatory drawing of the state installed hanging on the ceiling.

Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 shows an embodiment of the present invention, and FIG. 1 shows a state in which an automatic drop type fire bomb is installed on the ceiling. In the figure, a fire extinguishing bomb 1 in which a fire extinguishing agent is sealed in an impact rupturable container is suspended from a ceiling 2 of a building with a thread 3 and installed on the ceiling 2. The thread 3 has an upper end fastened to a hanging bracket 4 fixed to the ceiling 2 and a fire bomb 1 attached to the lower end.

  The simplest method for automatically dropping the fire bomb 1 at the time of fire is to use a fine count synthetic fiber as the thread 3, and the fire bomb 1 is dropped by melting the thread 3 due to temperature rise at the time of fire. That is. The fire bomb 1 falls due to the melting of the yarn 3, the container bursts by impact with the floor, and the fire extinguisher is scattered to extinguish the fire.

  Moreover, it is also possible to use a bimetal for the metal fitting 4 for holding the fire bomb and to make the fire bomb 1 fall by the displacement of the bimetal, and its operating state is shown in FIG. As shown in the figure, the metal fitting 4 is opened by the displacement of the bimetal accompanying the temperature rise at the time of fire, and the fire extinguishing bullet 1 falls.

  An arbitrary design is applied to the fire extinguisher 1 so as to be suitable for the type of building and the interior. For example, the fire bomb 1 is covered with a cover 5 with colorful colors and patterns, or the fire bomb 1 is accommodated in a pot-shaped container decorated with artificial flowers. In this way, in addition to preventing the fire bomb 1 from being exposed, an arbitrary design is applied so that the fire bomb 1 itself is formed in a pendant style so as not to give a sense of incongruity when installed on the ceiling (or wall). Designed as an interior product and commercialized.

  Although the embodiment of the ceiling installation has been described above, the fire-extinguishing bomb 1 can be ruptured by the impact of a drop of several tens of centimeters. In this case, it is preferable to bundle an attachment member that can be selected by selecting ceiling installation or wall installation.

  Note that the means for suspending the fire bomb 1 in this application document is not necessarily limited to hanging downward using a thread or string, and the fire bomb 1 is placed on the ceiling 2 (or wall) as shown in FIG. It includes a means for hanging and holding, and is a general means for holding it in a state where it can fall toward the floor surface. When hanging on the ceiling 2, the fire bomb 1 is covered with the cover 5 and designed like a ceiling lighting fixture, so there is no sense of incongruity. Also, the suspension means loses its holding function due to a temperature rise in the event of a fire. The fire extinguishing bomb 1 is physically held not by control by a power source but by melting, strength reduction or displacement of the member used in the suspension means. Various means using such a phenomenon can be applied.
