Description

The invention relates to a system of a peripheral to a central axis console with a smoke detector, such as a smoke detector or a smoke alarm. The console is formed two- to four-part maximum and has a lower part with a back for attachment to a mounting surface and an upper part with a front side opposite the back. The console also has outside, between the back and the front, a circumferential groove around the central axis. In the circumferential groove one or more circulating around the central axis bulbs and / or light-conducting components are arranged.

A combination of a lamp with a trained as a smoke detector signaling means is already in the DE 200 02 364 U1 described and in Fig. 2 shown. The frame element attached directly to a floor slab serves as a support for the lamps in which a light source is arranged and which are suspended on the frame element. The frame element is arranged circumferentially around the smoke detector. The smoke detector is isolated from the frame element attached directly to the floor ceiling.

In the AT 502655 A4 describes a ceiling lamp with built-in smoke detector, which includes a heat radiating light source. In this case, an air intake is provided, which leads into the interior of the ceiling lamp. A temperature difference along the Luftansaugstutzens leads to a chimney effect in the air intake. The smoke detector is attached directly to the floor ceiling.

In the US 4,090,178 A1 is a combination of a fire detector and a lamp, consisting of a housing with a bottom and side walls described. The housing is open on the ceiling side. Opposite the ceiling, a lamp socket is centrally located on the housing, which also houses the fire alarm circuit. The fire detector is attached directly to the floor ceiling.

In the DE 20 2011 005 648 U1 is a frame member described with a groove in which a circulating light source is arranged. The frame element is attached directly to a floor ceiling and is arranged circumferentially around the smoke alarm. The smoke detector is spaced from the frame element and thus insulated from the light source and is attached directly to the floor slab.

The invention has for its object to further develop a frame element with a smoke warning means as a console that the console supports early detection of smoke.

The object is achieved according to the invention in that the back forms an outer sides over which the console is installed. The upper part has on the front side an outer mounting surface on which the smoke alarm is attached directly or indirectly and the smoke alarm in turn has a housing with openings through which smoke can flow into the housing. The distance of the openings to the mounting surface of the upper part in the direction of the central axis is between 0.5 mm and 15 mm or at most 1.2 mm.

This ensures that smoke that spreads primarily along a floor ceiling, the mounting surface is directed to the openings on the housing. The attachment of the smoke alarm on the front of the console initially leads to a relatively large distance between the floor ceiling and the smoke detector, which would initially counteract early detection of smoke. Characterized in that the distance of the openings to the mounting surface of the upper part in the direction of the central axis does not exceed a certain extent, it is ensured that the light-conducting member is disposed directly under the floor slab. The spreading of the floor ceiling smoke is thus passed through the console and through the light-conducting component to the openings.

The claimed distances to the respective surfaces and to the openings correspond to the distances to the respective planes in which the respective surfaces or the openings are arranged.

The light source can also be arranged completely or else segmentally surrounding the frame element by the arrangement in the peripheral groove. The design of the arrangement of the luminous means is dependent on the task to be performed by the luminous means.

With regard to early detection of smoke, it may be advantageous if the smoke alarm has a housing with a bottom part and a lid, wherein the bottom part has an installation surface for attachment to the mounting surface, the openings are arranged on the bottom part and the installation surface directly or indirectly the mounting surface is applied. The openings in the bottom part allow a small distance of the openings to the installation surface and thus also to Floor slab or mounting surface. Through the two-part housing, a pre-installation of the bottom part of the console is possible.

An advantageous flow characteristic is also achieved in that the light-conducting component in the direction of the central axis M has a distance between 1 mm and 12 mm or a maximum of 3 mm to the back. The light-conducting component thus forms a guide element for smoke in the direction of the openings, which connect directly to the mounting surface. The light-conducting component extends in the radial direction to the central axis of the bulbs then between the front and back. As a result, the position of the light source is used to spread the light further in the radial direction. In addition, the light-conducting component also transports the heat of the bulb to the outside.

For the conduction of smoke, it may also be advantageous if the distance of the openings to the back in the direction of the central axis M is between 5 mm and 50 mm, in particular at most 12 mm. A low construction dimension of the console in the direction of the central axis requires a compact construction and very little or no distances between the successive in the direction of the central axis components. Larger gaps or gaps between the components would be detrimental to early detection of smoke.

An advantageous production and assembly can be achieved if the groove has a first groove flank and a second groove flank and between the two groove flanks the light-conducting component is arranged, wherein the lower part form the first groove flank of the groove and the upper part of the second groove flank of the groove. Such a construction brings significant advantages for the production and assembly with it, because with a small number of items low tooling costs and low assembly times can be achieved. For the installation of the console and for the mounting of the light source and in particular for the light-conducting component, it is advantageous if the division of the console takes place in such a way in the groove. Preferably, the upper part and the lower part are connectable to each other at least in the axial direction of the central axis, wherein the groove in a plane at right angles to the central axis is divisible by the compound.

With regard to a diverse selection of signal means may be advantageous for the present invention, if on the top of the lid, a receptacle is provided, in which at least one signal means is used, wherein in the receptacle electrical connections for control and / or power transmission to the signal means and / or are arranged on the smoke warning agent, which pass through the lid and through the bottom part. By the electrical connections a networking of several smoke alarms and the control of centrally arranged in the recording signal means are possible. The signal means can also be controlled via the radio interface.

For a precise and unambiguous recognition of the state of the signal, it is advantageous that an LED is provided which generates medium or direct optical signals on the surface of the lid.

For the power supply for control and / or power transmission, it is advantageous if the console has a cavity for reducing the heat transfer.

Through the cavity heat transfer from the bulbs on the console on the smoke warning is reduced or completely prevented.

For such a system it is advantageous if a battery, electrical connections for control or power transmission and / or a radio interface for a control and / or power transmission are arranged in the cavity. Wireless control over the interface enhances ease of use for both business and personal use. The interface operates in a voltage range between 0.01 - 10 volts and 100 - 250 volts. The electrical connections are passed through the lid and through the bottom part. In most cases, the console is mounted on a ceiling or wall with appropriate cables laid. These cables can be connected via the electrical connections to one or more components or consumers in the system. In cases where a stationary supply with cable is not guaranteed, the system is supplied with a rechargeable battery.

An individual adaptation of the system and reliable monitoring advantageously achieved in that in the console (1) a storage medium is arranged, the control and switching signals for the smoke detector and / or for the lighting means and / or for the signaling means as well stores for the optical signal means, wherein the data stored in the storage medium can be read out via the interface or via the electrical connections. Such a system permits remotely controlled room monitoring as well as an evaluation of the operating data of the system.

With regard to the combination of a smoke warning device with a light source (2), it may be advantageous if the console is formed at least partially from a material having a thermal conductivity of at most 1 W / (m * K) or at least 10 W / (m * K) is. Thus, metal, but also plastic, can be used for the console. Due to a good heat-conducting property, the heat of the light source is quickly absorbed by the console and released into the air. The console has an almost equal distribution of the surface temperature. Depending on the heat output, the console could additionally be designed with cooling ribs to increase the surface area and to be able to deliver even more heat for the same radius. A low thermal conductivity ensures that the console isolates the waste heat of the lamp, so that the heat can not propagate in the direction of the recess to the smoke detector.

An advantageous introduction of the smoke into the housing of the smoke detector is achieved in that the openings are arranged n a side wall of the bottom part, wherein the side wall is arranged with respect to the central axis at an angle a between 25 ° and 65 ° and the bottom part in the direction the central axis to the upper part is wider or narrower. Such a relation to the central axis conically tapering or conically diverging shape leads depending on the direction of propagation of the smoker to a faster detection.

With regard to optical networking of such systems, it may be advantageous if the consoles can be connected to one another directly or mechanically and / or light-conductingly via the components. For this purpose, it may be advantageous if between at least two consoles light-conducting intermediate component is provided, via which at least two light-conducting components are mechanically and / or light-conducting interconnected. The modular design includes the solution that the consoles via the light-conducting components themselves or via intermediate components medium or direct mechanical and / or photoconductive are connected to each other. The light-conducting components and the intermediate component are formed from glass or from a translucent plastic. In the modular design, the juxtaposed and luminous construction and intermediate components form light corridors or signal lines, for example, to display and illuminate an escape route.

For this purpose, it may be advantageous if a light source is arranged in the receptacle of the first console and a loudspeaker or a camera is arranged in the receptacle of the second console. The field of application of such systems is thus increased.

It may be advantageous if security system consisting of one or more consoles or a modular system according to one of the preceding claims with an electronic control unit, wherein at least a first signal means an electronic signal to the electronic control unit is transferable and the electronic control unit an acoustic and / or optical signal causes at least one second signal means.

For this purpose, it is also advantageous if one or more lamps change their optical properties depending on one or more signals of a smoke detector.

It is also advantageous if the properties of the lighting means and / or of the lamps of at least one console can be controlled as a function of the properties of the lighting means and / or the lamps of another console.

The security system comprises a plurality of consoles as well as light-conducting construction and intermediate components and an electrical signal means positioned in the respective receptacle. The signaling means is preferably designed as a lamp, as a loudspeaker or as a camera. Between smoke detectors, smoke detectors and smoke detectors is not distinguished according to the invention. Other electrical or hydraulic signaling means may be motion detectors or serve for fire extinguishing.

According to the invention, the module system is connected to an electronic control unit, wherein an electronic signal can be transmitted to the electronic control unit through at least one first signal means and the electronic control unit effects an acoustic and / or optical signal on a second signal means. This ensures that the individual signal means can be logically linked together. A loudspeaker is preferably arranged in the receptacle of a console, and an electronic signal of the smoke warning device to the electronic control unit generates an acoustic signal or a voice command via the loudspeaker. The signal of the smoke detector to the electronic control unit contains information about where and, if so, what type of flue gases is detected. Depending on the electronic control unit is a voice command or an acoustic signal in a speaker in another console generated. By the acoustic signal passers-by are warned. With the voice command, passersby are acoustically shown the shortest escape route.

It is advantageous if one or more lamps and / or lamps change their properties depending on one or more signals of a smoke detector. Properties are in particular the light color, the flashing frequency, the flashing phase and the brightness. With the help of bulbs and / or lamps, passers-by are visually signaled the escape route.

In this case, the properties of the lighting means and / or the lamps of at least one console can be controllable in dependence on the properties of the lighting means and / or the lamps of another console. As a result, for example, in one direction of several consoles along a path, a running light signal can be generated because the lamps and / or lamps of a first console a few milliseconds before or after the adjacent console shine or flash. A corresponding series circuit of more than 5 consoles causes current light signals.

The electrical signaling means are adapted to the degree of recording and due to their same or similar diameter in a console interchangeable.

a view in the direction of the central axis according to section VII-VII 'after Fig. 1 ,

In the Figures 1 and 2 Different views of a console 1 are shown. The respective console 1 is formed in two parts from an upper part 1.2 and a lower part 1.1. The upper part 1.2 is directed with its front 1.20 down and the lower part 1.1 with its back 1.10 upwards. With the back 1.10, the console 1 is attached to a mounting surface 9 designed as a ceiling. By the front 1.20 a perpendicular to the central axis M extending mounting surface 1.21 is defined for a smoke detector 3. An installation on a room wall is also possible, whereby the two surfaces 1.10, 1.20 would face each other in the horizontal direction.

At the attached to the mounting surface 9 lower part 1.1, the upper part 1.2 is fixed in the axial direction down. The connection between the two parts 1.1, 1.2 is not shown in detail and can be done by classical screwing or by a provided on the lower part 1.1 thread and a corresponding, provided on the upper part 1.2 thread.

Between the lower part 1.1 and the upper part 1.2 a circumferential and radially outwardly open groove 1.3 is formed. One groove flank forms the lower part 1.1 and the other groove flank forms the upper part 1.2. In this groove 1.3 are in accordance with the FIGS. 1, 2 and 7 positioned on an outer side of the console 1, the bulbs 2, so that the light emitted in the radial direction to the outside.

In the groove 1.3, a light-conducting component 7 is mounted between the upper part 1.2 and the lower part 1.1. In this case, the two groove flanks are fixed to the light-conducting component 7, so that the component 7 is fixed. The component 7 can be formed from glass, plastic, natural stone or any other light-conducting material. Glass is preferably used because it is very good heat-conducting and thus transports the heat from the bulbs 2 in a direction away from the smoke warning means 3. In one embodiment, not shown, the lighting means 2 are arranged in the component 7.

The heat of the light emitting means 2 may be detrimental to the smoke alarm 3 and is received via the console 1 and discharged into the air. For optimum insulation, a cavity 1.4 is formed in the lower part 1.1. This creates an air cushion as insulation.

The housing 3.1 of the smoke detector 3 is formed in two parts from a cover 3.4 and a bottom part 3.6. With the bottom part 3.6, the housing 3.1 is attached directly to the upper part 1.2 of the console 1. For this purpose, the upper part 1.2 has a fastening surface 1.21 provided on the front side 1.20.

In a side wall 3.7 of the bottom part 3.6 openings 3.3 are provided through which smoke can flow into the smoke detector 3. The side wall 3.7 is set against the central axis M by an angle a of 45 ° such that the bottom part 3.6 is wider towards the ceiling. As a result, smoke penetrates faster into the housing 3.1, which flows from the cover 3.4 to the bottom part 3.6. In an embodiment not shown, the bottom part 3.6 is narrower towards the ceiling. For this purpose, the side wall 3.7 is also employed at 45 ° to the central axis M, but in a direction rotated by 90 °. This geometry leads to earlier detection of smoke spreading from the bottom part 3.6 towards the lid 3.4.

The openings 3.3 in the side wall 3.7 are arranged according to the invention at a distance 8 of a few millimeters to the mounting surface 1.21. The upper part 1.2, which clamps the light-conducting component 7 is formed very thin. At the same time, the distance 8.1 of the light-conducting component 7 to the rear side 1.10 of the lower part 1.1 is very small. Together, there is a very small distance 8.2 between the mounting surface 9 or the rear side 1.10 and the openings 3.3. This flat design allows the console 1, together with the light-conducting component 7, to conduct the smoke propagating on the floor ceiling or on the mounting surface 9 to the openings 3.3.

Coaxially to the central axis M, the console 1 has a central receptacle 3.7, which is formed as a trough. In the recording 3.7, a signal means 4-6 is positioned, as in the Figures 3-6 is shown. FIG. 3 shows a plan view of a system of a console 1 and a smoke detector 3, in which a lamp 4 is inserted.

In Fig. 7 is a view of the console 1 after the cutting guide VII-VII 'according to Fig. 1 shown with a smoke warning means 3. The component 7 is shown cut in the radial direction with respect to its peripheral contour shown as a freehand line. The circumferential contour can have any symmetrical and asymmetrical shape taking into account the thermal properties.

According to the Figures 4-6 are more consoles 1 modularly connected via the component 7 or an intermediate component 10 light-conducting together. Several such modularly combined consoles 1 provide a security system in which the signaling means 4-6 are logically linked together via an electronic control unit. In the figures, for example, a plurality of such consoles 1, 1, 1 '' with different signal means 4-6 shown in the receptacles 3.7 and form a security system for the case of fire.

According to FIG. 4 is a first console 1 without a recording and equipped without a signaling means and the second console 1 'with a lamp 4 in the receptacle.

In the FIGS. 5 and 6 are as further signaling means 4-6 a speaker 5 and a camera 6 are provided. The smoke alarm 3 passes an electronic signal to a not shown control unit, via which the speaker 5 is controlled in a second console 1 'for an announcement. The three consoles 1, 1 ', 1''according to FIG. 5 are connected via a photoconductive intermediate member 10.

According to the embodiment according to FIG. 6 At the same time several lamps 4, 4 ', 4''in several consoles 1, 1, 1''arranged. The lamps 4, 4 ', 4''flash in such different frequencies that a flashing sequence oriented in the direction of the escape route (arrow) is generated as a running light signal, optionally with a color change. Such current light signals form light corridors or signal lines, which serve to orient the escape route.

In the Fig. 1 to 7 the same parts are numbered with the same reference numerals. Unless all the same parts are numbered, the numbering has been omitted for reasons of clarity.
