Description

[Detailed description of the invention] This invention is a pachinko hall that enables centralized management of fire occurrence conditions in pachinko halls, especially in pachinko machine islands where multiple pachinko machines are installed back to back and laterally. The present invention relates to a notification device.

Recently, fires have been occurring one after another in pachinko halls, and this has become a major problem. It is said that the most common places where these fires occur are on islands where pachinko machines are installed. There are several dangers due to the structure of such islands where pachinko machines are installed. For example, the inside of a pachinko machine installation island has complicated electrical wiring, so if a temporary excessive current flows for some reason, or if the wiring connection is unstable, it will generate heat, and this will cause the code to ignites and spreads rapidly, resulting in a large fire. In addition, oil-containing dust accumulates inside pachinko machine islands, and there are many causes of fires, such as sparks caused by short circuits in electrical wiring igniting this dust.

On the other hand, even if a pachinko hall is equipped with a fire detector, it is installed on the ceiling like in a general building or hotel, so if a fire breaks out from the island where the pachinko machine is installed, there is sufficient protection. The drawback is that it cannot fulfill its role, and this is an issue that must be resolved as soon as possible.

The present invention solves the above-mentioned drawbacks, and is a new system that can remotely monitor the occurrence of fires on islands where pachinko machines are installed, as well as quickly detect the occurrence of fires on islands where pachinko machines are installed and take early fire prevention measures on an island-by-island basis. The purpose of this invention is to provide a fire alarm system for pachinko halls.

In the present invention, the detectors that detect the occurrence of a fire are installed in the space directly above the pachinko machine stands that are installed back to back on the pachinko machine installation island, and at multiple locations in the longitudinal direction of the pachinko machine installation island. The pachinko machines are constructed so that fires can be detected at the top of the pachinko machine islands, where heat and smoke are most easily transmitted. in this way,
Since the occurrence of a fire can be detected early, extinguishing operations can be carried out at an early stage.

In addition, the display section for displaying the fire detection status of the fire detector is installed on the common panel of the display device located far from the pachinko machine installation island, and these display sections are separated by pachinko machine installation island. It is structured in such a way that it can be identified. In this way, it is possible to remotely and centrally monitor the situation of fire outbreaks on the islands where pachinko machines are installed, which not only makes it possible to save labor in the hall, but also allows early fire prevention measures on an island-by-island basis.

Furthermore, in this invention, the fire detector corresponding to the pachinko machine installation island and the display section of the display device are connected in series, so that the display state of the display section of the fire detector that detects a fire can be maintained by itself. It has a circuit configuration. In this way, the fire detection state is set until the reset switch is operated, making it possible to reliably notify the staff of the fire occurrence state.

Next, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, a is a general pachinko machine installation island a, and the right half shows the internal structure. Namely, 1, 1... are a large number of pachinko machine stands arranged back to back, 2 is a lower base plate on which the pachinko machine stands are installed, and 3 is a decorative panel attached to the frame 4 that supports the upper part of the pachinko machine stand. It is. 5 is a fire detector, and in this embodiment, as shown in FIG. 3, when the temperature rises rapidly, the air inside the heat sensitive chamber 6 expands
A well-known differential spot type is shown which presses a diaphragm 7 to close a contact 8 and issue a fire signal, and a wooden screw is attached to a crosspiece 10 or a top plate that extends directly above a space 9 between pachinko machine stands 1, 1, . . . It is attached using appropriate fixing means. Therefore, the crossbar 10 functions as a holding means for fixedly holding the plurality of fire detectors 5 at appropriate intervals in the longitudinal direction of the island.

The fire detectors 5 are provided at a plurality of locations in the longitudinal direction at appropriate intervals depending on the scale of the pachinko machine installation island a. It is very convenient to attach the warning light 11, which lights up in response to the fire signal, to the upper part of the outside of the pachinko machine installation island a.

Reference numeral 12 denotes a display device installed at a location away from each pachinko machine installation island a, such as a prize exchange booth or a management room in the hall, and a common panel on the front thereof displays the fire detector 5 for each pachinko machine installation island. A display section 14 is provided to display the fire detection state by lighting, and a number 13 is displayed for each display section to identify the corresponding pachinko machine installation island. Furthermore, an alarm device 15 such as a buzzer that issues an alarm when the fire detector 5 corresponding to one of the pachinko machine installation islands detects a fire, and a state in which the alarm device 15 issues an alarm by manual operation. A reset switch 16 is provided to release the reset switch. Further, the fire detector 5 and the display section 14 are each connected in series,
The circuit is configured to self-maintain the display state of the display section corresponding to the pachinko machine installation island of the fire detector that detected the fire.

Next, the operation of the present invention will be explained with reference to FIG. For example, if a fire breaks out on the pachinko machine installation island ^a1 of No. 1, the contact 8 of the fire detector 5 will close due to the rise in temperature and will issue a fire signal. Then, in response to that signal, relay R ₁ is activated and the panel of the display device 12 installed at a location away from the island is displayed.
The lamp on the display section 14 at the location where NO1 is displayed lights up to indicate that a fire has broken out on that island. At the same time, the alarm 15 sounds to inform the guests in the hall of the occurrence of a fire. This fire detection state is set by the self-holding function of the relay until the reset switch 16 is operated.

In this way, when a fire occurs on a pachinko machine installation island, the fire detector immediately detects it and issues a signal, and the display unit 14 corresponding to the pachinko machine installation island of the fire detector that detected the fire on the display device 12 lights up. This allows the staff to be reliably informed of the state of the fire, and also allows the pachinko machine island where the fire occurred to be confirmed at a glance, which is useful for early extinguishing efforts.

FIG. 4 is a circuit diagram when a well-known air tube type fire detector 18 is used in place of the above-mentioned differential spot type detector, and FIG. This is a circuit diagram in the case of using a so-called sensing wire type in which the sensing wire 20 is coated in an insulating state. In the case of the air tube type, as with the differential spot type, the air in the air tube 18 expands as the temperature rises, closing the contacts and emitting a fire signal.
On the other hand, in the case of the sensing wire type, the resin 19 melts due to temperature rise and the insulation state is released, causing the sensing wire 20 to melt.
By short circuiting, the circuit is closed and a fire signal is emitted. These can be piped next to the cords strung around the pachinko machine installation island a, allowing early detection of abnormal heat generation phenomena in the cords, and thus alerting the user of the danger of a fire in advance. It is also possible to prevent this from happening.

In addition to the above-mentioned embodiments, it is also conceivable to use a well-known smoke tube type fire detector. As is clear from the above explanation, according to the present invention, the fire detector is installed in a holding member separated from the hall ceiling in the space directly above the upper ends of the pachinko machine machines arranged back to back on the pachinko machine installation island. Since the pachinko machine was installed in the entire lengthwise direction of the island where the pachinko machines were installed, a fire that occurred inside the island could be prevented because the island had a sealed structure around all four sides and had a space between it and the ceiling of the hall. As it spreads only internally, it creates an updraft, and the heat and smoke are always transmitted to the upper part of the island and blown up, making it possible to quickly and sensitively detect and notify the outbreak of a fire. In addition, each island is equipped with a warning light, so you can quickly identify the island where the fire is occurring and discover it early. Therefore, the fire extinguishing work can be carried out quickly and a large fire such as spreading to the ceiling of the hall can be reliably prevented.

In addition, it is possible to centrally manage the fire situation on each pachinko machine island in the entire hall while staying in a remote location such as the prize exchange booth or the control room, so employees are not required to inspect the entire hall. There is no longer a need for patrolling and monitoring, which greatly contributes to hall management, such as reducing the number of personnel and saving labor for inspection work. Furthermore, since the location of the fire can be found accurately and quickly, extinguishing operations can be carried out quickly, which brings about many benefits, such as preventing a large fire from spreading to the ceiling of the hall.
