Description

Luminous fire fighting access panel mark

Technical Field

The present invention is a lighted fire passageway panel sign adapted to be secured to a designated fire passageway panel. Such illuminated fire passage panel indicators can be programmed to flash or change color when connected to a home automation device to alert the public or rescue personnel to serve as an alarm device.

Background

To enable rescue and exterior fire operations to be performed efficiently, buildings have been designed to include exterior access to the building for fire suppression and to provide access to fire fighting equipment. Such an exterior channel may be a window, balcony door, glass wall panel or solid wall panel that is openable from the exterior of the building. Firefighters can enter the building from the outside through the fire exterior access panel to rescue any personnel trapped within the building and to allow fire fighting work to be performed from outside the building.

Established requirements for fire-fighting access panels include: placing such panels in habitable spaces and restrictions from being placed at protected stairways or halls.

In singapore, in order to allow fire fighters to find a given fire passage opening, the fire passage panel should be marked with a red or orange equilateral triangle (150 mm minimum on each side) which can be set upright or inverted on the outside of the wall and marked on the inside with the word "fire passage-don't block" at least 25 mm high.

Traditionally, such signs are simple passive signs that are affixed or printed on designated fire way panels. It may take some time to locate the logo if there is insufficient ambient lighting or during a power outage. In an emergency situation, it is crucial to find the fire access panel quickly.

Disclosure of Invention

In the present invention, a novel fire fighting access panel sign is disclosed that includes a light emitting element such as a sign inlaid with an LED or light emitting strip. The use of LEDs or light emitting strips allows the illumination of the sign with low power consumption. If the fire access panel is made of glass, such as a window, glass wall panel, or balcony door, the sign may be secured between a pair of spaced apart glass panels to secure it in place and for ease of maintenance. Such illuminated fire passage panel identification may be connected to a power source via a wire. The power source may be a battery, a rechargeable battery, or an AC/DC power source. In addition to using a pair of wires, printed wire on a glass panel, copper tape or etched ITO (indium tin oxide) circuitry may also be used to connect the sign to a power source to illuminate the sign. Such lighted fire fighting access panel signs can easily locate the fire fighting access panel when the external ambient light is weak, such as at night or under severe weather conditions (such as heavy rain or haze). The use of printed wires, etched ITO, allows the glass panel to maintain a neat/clean appearance because no wires can be seen extending from the lighted fire passage panel sign.

Where the fire access panel is made of glass, the illuminated fire access panel indicator may also be affixed to either surface of a single glass panel or to the outer surface of a pair of spaced apart glass panels. If the fire doorway panel is opaque, a lighted fire doorway panel sign may be affixed to the surface of the panel outside the building.

A separate power source is contemplated for the lighted fire access panel sign so that the sign can continue to operate during a power outage or when the power source is turned off during a fire. Thus, power for the rechargeable battery may be provided by a solar panel embedded between two glass panels, placed on the outer surface of a glass panel or opaque wall panel, or placed separately from the fire passage panel to receive solar energy, which is then converted to electrical energy and stored in the rechargeable battery.

The lighting of the fire passage panel sign of the present invention may be controlled by an external device to generate an alarm signal upon a specific trigger, such as when a specific unit in a building catches fire. The light of the sign may be programmed to flash (rather than illuminate continuously), or change color, to alert surrounding occupants, or generally personnel within a visible range from the building.

Detailed Description

One or more specific and alternative embodiments of the present invention will be described below with reference to the accompanying drawings. It will be apparent, however, to one skilled in the art that the present invention may be practiced without such specific details. Some of the details may not be described in detail in order to avoid obscuring the invention. For ease of reference, when referring to the same or similar features in the drawings, a common reference number or series of numbers will be used throughout the drawings.

Fig. 1 is a front and side view of a fully assembled lighted fire shaft panel sign 30 mounted on a designated fire shaft window panel. The window panel is comprised of a pair of spaced apart glass panels and a lighted fire passage panel sign 30 is sandwiched between the pair of

glass panels

10 and 20. The body of the lighted fire fighting access panel sign 30 can be formed of a translucent non-conductive material such as acrylic, polycarbonate, plastic, PVC, and glass, and supported by a frame coated with a luminescent paint. The colour and dimensions of the sign 30 are suitable for use in section 4.2.3(d) of local regulations, such as "Chapter 4, site planning EXTERNAL fire regulations (Chapter 4, SITE PLANNING exterior FIRE FIGHTING pro vision)" of the singapore civil defence legislation.

The body of the sign 30 acts as a light diffuser to uniformly diffuse the light as it passes through. An LED light bar or strip 40 is disposed around the body of the lighted fire way panel sign 30 with a pair of wires 50 electrically connected to the cathode and anode of the LED light bar/strip 40. The pair of electric wires 50 extends between the gaps of the pair of

glass panels

10 and 20 and is connected to an external power source. The external power source may be controlled by an automated device to determine when to turn on the LED light bar/strip 40. For the present embodiment, a light sensor 60 is embedded between the pair of

glass panels

10 and 20 to detect ambient lighting conditions to illuminate the LED light bar/strip 40 at a specified detected light intensity. Alternatively, a timer may be used to turn on the lights of the sign 30 for a specified period of the day. The light sensor 60 is connected to an external control circuit by a wire 61. This lighted fire shaft panel sign 30 provides convenient location for the fire shaft panel on the outside and for the opaque fire shaft panel on the inside during an emergency. The frame of the illuminated fire passage panel sign 30 may be formed of any color of opaque material as required by the local requirements, or may be formed of opaque material sprayed, painted, or covered with colored tape.

Figures 2 and 3 show that lighted fire shaft panel signs 30 are placed on either side of a given fire shaft window panel made of a single glass panel. Because the window panels allow light to pass through, the illuminated fire passage panel signs 30 can be mounted on either side of the window panels and still be visible from outside the building.

Fig. 4 shows the lighted fireman way panel sign 30 powered by an external power source 270 or rechargeable battery 200. The solar panel 100 is placed between a pair of spaced

apart glass panels

10 and 20, forming a border around the glass panels. The solar panel 100 is used to collect solar energy for storage into the rechargeable battery 200. The solar panel 100 may be a single crystal silicon, polycrystalline silicon, or even a thin film amorphous silicon solar panel. The rechargeable battery 200 is placed in the space between the pair of

glass panels

10 and 20. One end of a pair of wires 250 is connected to the cathode and anode of the LED light bar/light emitting strip, and the other end of the pair of wires 250 is connected to the rechargeable battery 200. The rechargeable battery 200 serves as a backup power source in case the external power source 270 is cut off for any reason. A switch charger 280 may be located outside the window panel to automatically switch power between the battery 200 and the external power supply 270. The solar panels may also be located on the exterior surface of the glass fire passage panel or separate from the passage panel in any part of the building that may be exposed to sunlight.

Fig. 5 shows that the rechargeable battery 210 is located outside, rather than being embedded between the pair of

glass panels

10 and 20. Under normal conditions, an external power supply 270 is connected to the end of the wire 250 via a switch charger 280 to power the LED light bar/lighting strip 40. If the external power supply 270 is cut off for any reason, the switch charger 280 can detect this and automatically switch to the battery 210 to power the LED light bar/lighting strip 40 via the wires 251. In addition, when the power generated by the solar panel is insufficient, the battery 210 may be charged by the external power supply 270 through the switch charger 280.

Fig. 6 and 7 show a solar panel 100 and a lighted fire shaft panel sign 30 placed externally on either side of a fire shaft window panel made of a sheet of glass panel. Its function and performance are the same as the assembly of fig. 5, but it lacks aesthetics and has maintenance issues.

Figure 8 shows a lighted fire shaft panel sign 30 externally placed on an opaque fire shaft panel 300.

While particular embodiments have been described and shown, it should be understood that the invention is capable of numerous changes, modifications, variations and combinations, without departing from the scope of the invention. For example, wires extending from lighted fire way signs can be embedded in opaque fire way panels to maintain a clean/tidy appearance and ease of maintenance.
