Description

The invention relates to a modular security system with a console for receiving the same or different signal means, which can be used in particular in case of fire. The security system includes a console with a light source and a modular system for combining with different signal means. The console itself consists of a frame element. The frame element comprises an upper part with a front side, a lower part with a rear side for mounting on a mounting surface and the middle or directly on the frame element arranged bulbs.

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 member serves as a support for the lamps in which a lighting means is arranged and which are suspended on the frame member.

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.

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.

In the DE 199 04 933 C1 is a lamp described with a roof having a housing in which an annular lamp is provided. The lamp and the roof define an interior in which various installation parts are provided, such as a smoke detector.

The WO 2009/105168 A2 describes a luminaire with a centrally arranged luminous means and a plurality of light-conducting elements arranged around the luminous means for relaying or redirecting the light emitted by the luminous means.

From the WO 2010/054346 A1 is a console with bulbs and a camera known, which has a frame member with a top and a lower part. The bulb is sandwiched between the top and bottom. The frame element also has a recess extending in the axial direction, which serves to receive the camera or a camera housing. Between the camera body and the frame member, a gap is formed.

The invention has the object of developing such security systems such that the signal means are not affected by the light source in their function and at the same time a modular and safety-enhancing combination of such systems is possible.

The object is achieved according to the invention in that the frame member is at least two parts in the direction of a central axis and between the front and the back at least one on the outside around the central axis at least partially circumferential groove having a groove bottom forming outside. In the groove, the light source is arranged. The frame element has a recess extending parallel to the central axis and extending over the height of the frame element, with an inner side delimiting the recess. The inside limits the recess in the radial direction to the central axis. The recess serves to receive an electrical signal means. According to the invention, the frame element isolates the signal means from the conductive and convective waste heat of the luminous means, wherein a light-conducting component is mounted in the groove, which extends in the radial direction to the central axis between the two planes of the front and rear sides.

According to the invention, a light-conducting component is mounted in the groove, which extends in the radial direction to the central axis between the two planes of the front and back. The plane E1 runs on the front and the plane E2 on the back, each perpendicular to the central axis. As a result, the position of the light source is used to further propagate the light in the radial direction. In addition, the component also transports the heat away from the heat-sensitive signal means. The component is connected without or with a connection joint of not more than 0.2 mm both in the axial and in the radial direction to the central axis at the front of the frame member.

Due to the two-part design, the light source can be integrated into the frame element far enough that the signal means to be arranged centrally can be positioned entirely in the radiation shadow of the light source by the frame element. This is particularly advantageous if a smoke detector is used as the signal means. For this purpose, the recess is formed as a continuous, coaxial to the central axis arranged opening, so that the signal means can be sunk in the direction of the central axis as far as possible in the frame member. For this purpose, the frame element according to the invention is plate-like and set back relative to the signal means on the mounting surface.

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.

For the installation of the frame member and for the mounting of the lamp, it is advantageous if the division of the frame element takes place in such a way that the upper part forms a first groove flank of the groove and the lower part forms a second groove flank of 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.

The frame element is made of a material with a thermal conductivity of at most 1 W / (m * K) or at least 10 W / (m * K), so that metal but also plastic can be used. By a good heat-conducting property, the heat of the bulb is quickly absorbed by the frame member and released into the air. The frame element has an almost equal distribution of the surface temperature. Depending on the heat output, the frame member could be additionally formed with cooling fins to increase the surface area and to be able to give off more heat at the same radius. By a low thermal conductivity is achieved that the frame element, the waste heat of the bulb isolated, so that the heat can not propagate in the direction of the recess to the signal means.

It can also be advantageous if the frame element has an insulating layer arranged in the radial direction to the central axis between an inner side of the frame element and the lighting means. As a result, the heat conduction in the direction of the signal means is interrupted independently of the thermal conductivity.

So that the signal means, in particular smoke or smoke alarms, are not influenced by the lighting means, it is provided according to the invention that the size of the front side and / or the mass of the frame element is dimensioned as a function of the heat introduced by the lighting means such that at an ambient temperature of up to 20 ° Celsius, the surface temperature of the frame element on the front side is a maximum of 46 ° Celsius.

The modular structure includes the solution that the consoles via the components themselves or via intermediate components medium or direct mechanical and / or photoconductive are connected to each other. The components and the intermediate component are made of glass or of a translucent Plastic formed. 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.

The safety system comprises a plurality of consoles as well as building and intermediate components and an electrical signal means positioned in the respective recess. The signaling means is preferably designed as a smoke detector, smoke detector, as a lamp, as a loudspeaker or as a camera. Between 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. Depending on the function of the signal means it is flush with the front of the console in the axial direction to the central axis or protrudes from the front by a dimension between 1 mm and 80 mm. Loudspeakers can be mounted flush, whereas smoke and smoke detectors are available for better detection of flue gases.

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. Preferably, in the recess of a frame member, a smoke detector and in the recess at least one other frame member a speaker arranged and an electronic signal from the smoke detector to the electronic control unit is an acoustic signal or a Voice command generated via the speaker. In case of fire, a smoke detector detects flue gases. A signal from the smoke detector to the electronic control unit provides information about where and, if so, what type of flue gases are detected. Depending on this, a voice command or an acoustic signal is generated in a speaker in another console by the electronic control unit. By the acoustic signal passers-by are warned. With the voice command, passersby are acoustically shown the shortest escape route.

When combining a console with a smoke or smoke detector, it is advantageous if an air gap between 0.5 mm and 1.2 mm is formed between the frame member and the smoke or smoke alarm in any direction, so that the frame member and thus the Bulb is physically separated from the smoke or smoke alarm.

For this purpose, 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, a running light signal can be generated, for example along several consoles along a path, because the lamps and / or lamps of a first console few Milliseconds before or after the adjacent console light or flash. A corresponding series circuit of more than 5 consoles causes current light signals.

The electrical signal means are designed for receiving in the recess and due to their same or similar diameter in a console interchangeable.

FIG. 6

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

In the FIGS. 1 to 4 are sectional views of different consoles 1 shown. The respective console 1 has a frame element 1.0 with an upper part 1.1 and with a lower part 1.2. The upper part 1.1 has a front side 1.10 and the lower part 1.2 has a rear side 1.20. With the back 1.20, the frame member 1.0 is attached to a mounting surface 9 designed as a ceiling. By the front side 1.10 is a plane perpendicular to the central axis M extending plane E1 and defined by the back 1.20 also a right angle to the central axis M extending plane E2.

The frame member 1.0 is formed in two parts in the axial direction of the central axis M. At the attached to the mounting surface 9 lower part 1.2, the upper part 1.1 is fixed in the axial direction down. The connection between the two parts 1.1, 1.2 consists of an outer thread provided on the lower part 1.2 1.21 and a corresponding, provided on the upper part 1.1 internal thread 1.11. The threads 1.11, 1.21 extend in the circumferential direction about the central axis M and the upper part 1.1 is screwed onto the lower part 1.2. Between the lower part 1.2 and the upper part 1.1 a circumferential and radially outwardly open groove 1.3 is formed. In this groove 1.3 are in accordance with the Figures 1-3 positioned on an outside 1.12 of the frame member 1.0, the bulbs 2, so that the light emitted in the radial direction to the outside.

Coaxially with the central axis M, the frame element 1.0 has a central recess 1.5 (FIG. FIG. 1a ), which is formed as a continuous opening. Like also in FIG. 1a Shown in detail, the recess 1.5 is bounded by an inner side 1.4 of the frame member 1.0. In the recess 1.5 a signal means 3-5 is positioned, as in the Figures 2-4 is shown. The signal means 3-5 is thereby arranged centrally in the radial direction adjacent to the inside 1.4 of the frame element 1.0 in the frame element 1.0 and is fastened at the top to the same mounting surface 9 as the frame element 1.0. For clarity, the mounting surface 9 in the sketch spaced from the back 1.20 of the frame member 1 is shown. In the FIGS. 1a-4 the assembled position is shown.

The diameter of 3.1 in FIG. 2 shown smoke detector 3 is dimensioned for thermal reasons, that between the inside 1.4 of the frame member 1.0 and the smoke detector 3, an air gap 12 is formed between 0.5 mm and 1.2 mm. The smoke detector 3 has a slotted smoke cap 3.2 and an adjoining housing 3.3. With the housing 3.3 of the smoke detector 3 is also attached to the mounting surface 9. The smoke cap 3.2 protrudes downwards in the direction of the center axis M over the front side 1.10 of the frame element 1.0 by a dimension h of 34 mm. The smoke detector 3 is thus arranged in the radiation shadow of the lighting means 2. Characterized in that the bulbs 2 between the two through the front 1.10 and the rear 1.20 defined planes E1, E2 are arranged, a radiation direction in the radial direction away from the smoke detector 3 is easy to implement. The air gap 12 is also realized in all other modularly combined with the console 1 signal means 3-6, which are arranged in the recess 1.5 of the console 1.

In the groove 1.3, a light-conducting component 7 is mounted between the upper part 1.1 and the lower part 1.2 in the groove 1.20. In this case, the two parts 1.1, 1.2 form a first groove flank 1.31 and a second flute 1.32, between which 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 detector 3.

In the embodiment according to Fig. 3 the lighting means 2 are arranged in the component 7. The light sources 2 shown on both sides of the central axis M and positioned within the groove 1.3 can not emit light directly on the signal means 4, because the signal means 4 is arranged in the radiation shadow through the groove 1.3. The heat of the luminous means 2, which may be disadvantageous for the signal means 4, regardless of the generated radiation shadow, is absorbed by the frame element 1.0 and released into the air. The light sources 2, which are further away in the radial direction from the signal means 4, are unproblematic with respect to the light emitted to the signal means 4. The disadvantageous influence of heat also decreases with increasing distance of the lighting means 2 from the signal means 4. In an embodiment not shown, the lighting means 2 according to one of Fig. 1 to 2 with the bulbs 2 according to Fig. 3 combined in a frame element 1.0.

In a further embodiment, not shown, the upper part 1.1 is attached instead of a thread by attaching to the lower part 1.2 in the axial direction on the lower part 1.2 and thereby secured the component 7 in the groove 1.3. The lamps 2 may be positioned in this embodiment or in the embodiment described above on the lower part 1.2 or on the upper part 1.1.

The system combines with a smoke detector 3 according to Fig. 2 additionally has a spacer 8, which is arranged between the mounting surface 9 and the smoke detector 3. By means of the spacer 8, the smoke detector 3 can be adjusted in its position relative to the front side 1.10 or to the plane E1 in the axial direction to the central axis M.

In addition, in the embodiment according to Fig. 2 provided an insulating layer 14 in the lower part 1.2. For this purpose, the lower part 1.2 is constructed in several parts in the radial direction, so that heat conduction from the light sources 2 in the radial direction through the surrounding insulating layer 14 to the inside is prevented by the insulating layer 14.

In Fig. 6 is a view of the console 1 after the cutting guide VI-VI 'according to Fig. 1 with a smoke detector 3 according to FIG. 2 shown. The component 7 is shown cut in the radial direction with respect to its peripheral contour shown as a freehand line. The peripheral contour may have any symmetrical and unsymmetrical shape taking into account the thermal properties.

Several consoles 1 are connected in a modular fashion via the component 7 or via an intermediate component 13 in a light-conducting manner. The signal means 3-6 are logically linked to one another via an electronic control unit. In the Figures 5a-5c For example, a plurality of such consoles 1, 1 ', 1 "shown with different signal means 3-5 in the recesses 1.5 and form a security system for the case of fire.

According to FIG. 5a is a first console 1 combined with a smoke detector 3, which passes an electronic signal to a control unit, not shown, via which then a loudspeaker 5 in a second console 1 'is controlled for an announcement. To FIG. 5b the module is extended by a further console 1 "with a component 7 and by a fourth console 1"'with an intermediate component 13. The intermediate component 13 connects all components 7 in a light-conducting manner. The smoke detector 3 is arranged in the intermediate component 13, but a console 1 'receives a lamp 4 and the further console 1 "a camera 6.

According to the embodiment according to FIG. 5c 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 Escape route serve. In a further console 1 "', a camera 6 is used as a signal means for monitoring the emergency situation.

In the Fig. 1 to 6 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.
