DE202004018606U1 - Fire alarm triggered by presence of smoke or gas, has pointer with laser light diode fixed to base of sensor via ball shaped coupling - Google Patents

Abstract

The fire alarm comprises a sensor base (11), a pointer (12) mounted at the base and a controller built inside the base. The pointer is fixed to the base via a ball shaped coupling (122) so that it's position is adjustable. The pointer includes a laser light diode in a housing (121) at the tip of the pointer. The pointer (12) is connected to the controller via a conductor. The pointer fits to the sensor base (11) via a ring shaped adapter (111) with a curved inner surface so that the ball coupling (122) rotates and rolls against the inner surface of the adapter.

Description

The This invention relates to a fire alarm, and more particularly to a fire alarm, comprising an adjustable pointing device comprising a housing and one in the case built-in laser light emitting diode, which the fire detector at track down of smoke generated by fire, both in the form of a fire message responds as well as at the same time direct a laser light to the output can lead the firefighters to the right starting direction.

at The outbreak of a fire is vital as soon as possible the fire place to remove. According to the fire department experts, moments decide on that Life at the fire outbreak. It can be a matter of seconds whether people are moving away from the fireplace at the right time can.

nowadays is usually a common one Fire detector (generally a smoke detector based on smoke) in buildings built-in. When fire in the building breaks out, the fire detector is due to the breaking of the ultra-radar sensor respond to smoke and give a fire message. Because the burnt place is everywhere Smoke infested, could the lighting system due to the power failure by the fire fail. This makes it very difficult for people to exit to find.

ordinary Output display devices are provided with a battery, so that the output indicators also react during power failure can, to guide the person to the exit with the help of the illumination.

in the general are the conventional ones Output display devices provided with a neon lamp, the relative is weak, causing the lighting of the output display devices It is difficult to see in the smoke. This will allow the near or in the hearth itself people at risk be.

The The main object of the invention is to provide a device both for fire alarm as also provide as output indicator by a technical Medium is installed during the fire message can simultaneously direct a laser light on the output, to lead the people to the right exit.

Of the Fire alarm according to the invention comprises an adjustable display device comprising a housing and one in the case built-in laser light emitting diode, which the fire detector at track down the smoke generated by a fire, both in the form of a fire message responds as well as at the same time direct a laser light to the output can lead people to the right exit.

These The object is solved by the invention described in claim 1; advantageous Further developments are specified in the subclaims.

One embodiment The invention is explained below with reference to the drawing. In show the drawing:

1 a perspective view of a fire alarm according to the invention;

2 : a side view of the fire alarm according to the invention 1 ; and

3 : A side view of the fire alarm according to the invention in operation.

First, on the 1 and 2 Referenced. As can be seen from the figures, includes an inventive fire alarm 10 a sensor pedestal 11 , an indicator device 12 and a regulator 13 ,

The sensor pedestal 11 is a smoke-based fire detector according to the prior art, wherein the sensor pedestal 11 on the ceiling 20 can be attached. The sensor pedestal 11 is on the ground with an annular fitting 111 provided, the inner wall of a curved mating surface 112 having. The mating surface 112 is concave. At the sensor pedestal 11 is one on the controller 13 connected switch 113 attached, the switch 113 in this embodiment is a push button switch.

The pointing device 12 is adjustable on the sensor base 11 mounted, the pointing device 12 a laser light can radiate on the output to guide people to the correct output. The pointing device 12 has a housing 121 and a rule ball 122 on, with a laser light emitting diode in the housing 121 is installed. The line of the laser light emitting diode is connected to the fire detector, bringing the pointer device 12 can emit a laser light. The construction of the line is according to the prior art, so that a more detailed explanation is unnecessary here.

The rule ball 122 the pointing device 12 is rotatable in the fitting 111 built in, with the control ball 122 with its spherical surface 124 when adjusting against the mating surface 112 rolled. The spherical surface 124 is convex.

After the sensor pedestal 11 on the ceiling 20 is mounted, the housing can 121 the pointing device 12 due to the rule ball 122 be set to the correct angle. When you press the switch 113 gets a laser light from the case 121 emitted, bringing the user the laser light of the housing 121 unerringly can adjust to the exit.

The regulator 13 is in the sensor pedestal 11 built-in, with the housing in the 121 defined line of the pointing device 12 and the switch 113 on the controller 13 are connected.

With reference to the 3 Fire has broken out in the building, so that the fire site and the building are covered with smoke everywhere. Now the sensor subset 11 of the fire alarm react to the smoke. This will cause a fire message through the controller 13 given. At the same time, the one in the housing 121 built-in laser light emitting a laser light on an output 40 radiate to guide people to the right exit.

In everyday testing, the user can press the switch to make sure that the case is in the case 121 Built-in laser light diode works normally.

According to the above Descriptions may be the construction of the fire alarm according to the invention the disadvantage of the conventional Avoid systems for output indication. This is the task solved the invention.
