Description

The invention relates to a device for destroying a fragile, disk-shaped protective element by means of a destructive element for emergency devices protected by the protective element against unauthorized access, in particular hazard detectors, manual call points and storage boxes for emergencies, for example emergency key boxes, whereby this is destroyed by applying a shock pulse to the fragile protective element and the Access to a switching element or auxiliary means for opening doors, in particular emergency keys or electronic key cards, arranged behind the fragile protective element is made possible.

Such a device is used, for example, on emergency devices which are designed as manual danger detectors, in particular manual fire detectors, in which the location of the alarm state is displayed on a danger detection control center within danger detection systems. As a result, a collective report is generally sent to an emergency call center, in particular the fire service or the police.

Another possible use of this device is for emergency devices which are designed as storage boxes for emergencies, in particular emergency key boxes, and in which aids are stored in the form of emergency keys or electronic key cards so that, in the event of an emergency, these aids can be used to open otherwise secure escape doors, for example.

Such emergency devices designed as hazard detectors in the form of manual fire detectors essentially consist of a housing that is composed of a lower housing part and a housing door that is generally pivotable and covers or releases the lower housing part, the lower housing part being formed from a rear wall with a peripheral side wall. Furthermore, a printed circuit board equipped with electronic components and a switching element located in a control panel and triggering an alarm by pressing are provided in the housing, and on the inside of the housing door facing the lower housing part there is a fragile, disk-shaped access to the switching element Temporary preventing fragile protective element is arranged, which covers the inside of a recess provided in the housing door and a destruction element is arranged on the hazard detector to remove the fragile protective element in order to allow free access to the switching element for triggering the alarm message.

An emergency device in the form of a storage box for emergencies, for example an emergency key box, differs from the hazard detector described above only in that instead of the printed circuit board equipped with electronic components and the operating part with the switching element, means for suspension, e.g. Hooks, the emergency key or means for inserting or inserting the emergency key or the electronic key card are provided in the housing.

After DE 198 45 913 B4 a device for destroying a fragile protective element by means of a destructing element on an emergency device is known, which is designed as a danger detector in the form of a manual fire detector. This device is referred to there as an impact protection device for protection against splinters when the fragile protective element (impact glass made of impact glass) is impacted.

For this purpose, an elastic actuating element is provided for protection against splintering when the fragile, disk-shaped protective element located on the inside of a housing door is knocked in, which is arranged on the front of the hazard detector in the area above the fragile protective element in such a way that it at least partially covers the knock-in area and in a central raised area contains a switching element (pusher) to which the fragile protective element is assigned a destructive element in the form of a rigid destructive element consisting of a metallic ball or a metallic mandrel. The impact protection device is positioned outside the hazard detector above the impact area, whereby the elastic actuating element, in the event of an impact pulse directed at the actuating element with the impact element, on the one hand removes the fragile, disc-shaped protective element by destruction from the area of the recess in the housing door and on the other hand splinters shield the impact area.

The disadvantage of this solution is to be seen in the fact that the impact disk protection device with its movable, provided over the fragile element Impact element, the actuating element of which protrudes over the front of the emergency device or the housing door and thus positioned outside the emergency device above the fragile protective element and thus, in conjunction with the actuating element coupled to the impact element, there is a risk of unwanted damage to the fragile protective element, or also from the point of view of vandalism that the fragile element is animated. Unintentional damage to the fragile element can also be caused if the emergency device is exposed to shocks and / or vibrations during transport. Ultimately, the alarm triggering required for the manual call point by means of the switching element or the free access to the emergency key box or the electronic key card required for the emergency key box, cannot always optimally destroy the fragile element. That is, the fragile element is often only partially destroyed, so that its parts in the form of fragments and / or splinters, the recess in the housing door and the switching element or the emergency key or the electronic key card still completely or partially cover and therefore do not or do not actuate ... can only be carried out after manual destruction or if there is an increased risk of injury.

The object of the invention is to propose a device for the destruction of a fragile, disc-shaped element by means of a destruction element, the destruction element of which is designed to be immovable, does not protrude above the front of the emergency device or the housing door and is therefore not positioned outside the emergency device above the fragile element , which further effectively prevents unwanted damage to the fragile element and also does not apparently stimulate vandalism activities relating to the fragile protective element. Unintentional damage to the fragile protective element due to shocks and / or vibrations during transport of the emergency device should also be ruled out, and an expedient, alarm-triggering destruction of the fragile protective element can be optimally realized by the fragile protective element being completely destructible, so that its parts neither completely nor the switching element partially cover and thus no additional manual destruction actions on the fragile protective element are required for the actuation of the switching element, which ultimately also largely excludes the risk of injury.

This object is achieved in a generic emergency device with the features indicated in the characterizing part of protection claim 1, the advantageous embodiments of which can be seen from the protection claims 2 to 20.

The advantages of the invention consist in the fact that the fragile, disk-shaped protective element is destroyed and removed by means of a destructive element which is arranged firmly in the housing of the emergency device and which only has an inactive role since the protective element is deformed when a shock pulse is introduced in the form of a bulge can be used for the protective element to make active contact with the destructive element, so that an additional burst pressure is applied to it, ultimately causing the protective element to destroy the access to the alarm-triggering switching element, the emergency key or the electronic key card. The immovable destruction element does not protrude above the front of the emergency device or the housing door, nor is it located outside the emergency device above the fragile element. In this way, unwanted damage to the fragile element can also be effectively prevented and an incitement to vandalism activities to maliciously destroy the fragile protective element can be largely prevented. In addition, unintentional damage to the fragile protective element by shocks and / or vibrations during transport of the emergency device is excluded. Furthermore, a required destruction of the fragile protective element, which ensures free access to the switching element, the emergency key or the electronic key card, is carried out optimally by the fragile protective element being able to be completely destroyed, so that its parts neither completely the switching element, the emergency key or the electronic key card still partially cover and thus no additional manual destruction actions on the fragile protective element are required for the actuation of the switching element or access to the emergency key or the electronic key card, which ultimately also largely excludes the risk of injury.

The development of the invention according to claim 2 has the effect that the destruction element can be easily arranged on the lower housing part.

This represents a very compact embodiment, wherein the destruction element can also be part of the housing door. With this arrangement, the desired functionality is also ensured without the lower housing part.

The development of the invention according to claim 10 enables the destruction element to generate an effective burst pressure on the protective element when it is designed as part of the housing door.

The development of the invention according to claim 16 makes it possible, on the one hand, to secure the mounting of the protective element and, on the other hand, to implement a bulging which deliberately ruptures the protective element in an emergency.

The embodiment of the invention according to claim 17 ensures that the protective element can be provided in simple geometric shapes.

The embodiment of the invention according to claim 18 enables the protective element to be sealed off from the housing door without the operation of the protective element in connection with the destruction element being adversely affected.

In the 1 to 3 An emergency device 1 designed as a manual fire alarm is shown in the vertical installation position, which consists of a housing 2 with a lower housing part 3 and a closable housing door 4 covering the lower housing part 3. The lower housing part 3 is formed from a rear wall 5 with a circumferential side wall 6 and contains a printed circuit board 7 equipped with electronic components and a switching element 9 located in an operating part 8, by actuating, for example pressing, an alarm message can be issued.

On the inside 10 of the housing door 4 equipped with a window-like recess 11 facing the lower housing part 3, a circumferential edge 13 containing a support surface 12 adjoins the periphery of the recess 11, which in the outside direction extends from a perpendicular to the inside 10 of the housing door 4 above frame 14 is limited. A protective element 17, limited by side surfaces 15 with a peripheral edge 16 facing the lower housing part 3, is fragile, disk-shaped and, when the emergency device 1 is ready for operation (= rest position), temporarily prevents access to the switching element 9 and consists, for example, of glass or plastic of the support surface 12 lying and arranged within the frame 14 and thus vertically and horizontally secured against rotation on the inside 10 of the housing door 4. On the inner side 10 of the housing door 4 facing the lower housing part 3, the fragile protective element 17 is advantageously mounted at suitable points in its edge region by holding bolts 18 provided on, for example, two opposite sides.

In the lower housing part 3 is according to the Fig. 4 On the inside 19 of the rear wall 5 of the lower housing part 3, a vertically protruding destruction element 20 is rigidly arranged, which consists of a shaft 21 which, at its free end 22 facing the protective element 17, advantageously has a frustoconical head 23 ( Fig. 5 in conjunction with Fig. 4 ), spherical segment-shaped head 24 ( Fig. 6 ), ellipsoid segment-shaped head 25 ( Fig. 7 ), frustum-shaped head 26 ( Fig. 8 ) or a head 27 equipped in the direction of the inside 10 of the closed housing door 4 with a rising ramp surface ( 9 and 10 ), the respective head 23 to 27 with its end 22 when the emergency device 1 is ready for operation (= rest position) extends in this way to the lower edge 16 on the side surface 15 of the protective element 17 and a slight one which does not touch the lower edge 16 of the destruction element 20 Maintains distance. Regarding the frustoconical head 23 of the destruction element 20, the detailed illustration according to Fig. 11 referred.

The in the 2 to 4 exemplary embodiment of the invention includes the arrangement of the destruction element 20 on the inside 19 of the rear wall 5 of the lower housing part 3 and preferably with respect to the side surface 15 of the protective element 17 and its preferred configuration with the frustoconical head 23 Fig. 5 , wherein the fragile, disk-shaped protective element 17 is in its rest position.

This provides the fundamentally necessary prerequisites for the fact that in the event of an intended triggering of an alarm by force acting on the fragile protective element 17 and, if necessary, elimination by destroying the protective element 17 with the destructive element 20, the latter is arranged in such a way that the contact takes place of the protective element 17 with the head 23 of the destruction element 20 to ensure free and non-hazardous access to the switching element 9 by the operator.

In the case of a protective element 17 formed, for example, with a rectangular, square or round base surface, the destruction element 20 can be positioned on the side surfaces 15 both centrally ( 2 to 4 ) or be arranged off-center (not shown).

If the protective element 17 which is initially required for an intended alarm triggering is now realized, possibly by means of appropriate aids, and thus an impact pulse is applied to the protective element 17, as a result of which the protective element 17 between the retaining bolts 18 corresponds to the position shown in FIG Fig. 11 Dotted curvature 28 in the direction of the lower housing part 3 takes place inwards, so that the lower edge 16 of the relevant side surface 15 of the protective element 17 moves towards the frustoconical head 23 of the destruction element 20 while continuously reducing the former distance and comes into contact with the head 23 with a point contact of the destruction element 20 arrives. By this contact of the lower edge 16 of the protective element 17 with the frustoconical head 23 of the destruction part 20, a lateral burst pressure is additionally applied to the fragile protection element 17, so that it is destroyed with a high degree of certainty in connection with the impact pulse already initiated. At the same time, the elimination of the protective element 17 from the emergency device 1, in particular via the control unit 8 with the switching element 9, is accompanied by the fact that the intended alarm triggering can now be implemented unhindered and without risk by actuating the switching element 9.

An analogous destruction process of the fragile protection element 17 takes place if the destruction element 20 in the further developments of the invention has a spherical segment-shaped head 24 ( Fig. 6 ) or an ellipsoid segment-shaped head 25 ( Fig. 7 ) is executed. Here, too, there is point contact due to the curvature on the protective element 17 produced by the action of force, with the head 24 in the form of a spherical segment or the head 25 of the destroyer element 20 in the form of an ellipsoid segment, whereby this Bulge 28 essentially analogous to that Fig. 11 represents.

The destruction of the fragile protective element 17 is similar if the destruction element 20 has a head 26 which is truncated pyramid-shaped ( Fig. 8 ) and, in the idle state, one of the trapezoidal lateral surfaces is arranged parallel to the edge 16 on the side surface 15 of the fragile protective element 17 or the head 27 has an ascending ramp surface ( 9 and 10 ) and this run-up surface is designed to run parallel to the peripheral edge 16 of the fragile protective element 17 facing the lower housing part 3. In this case, however, a line contact occurs through the arching produced on the protective element 17 with the head 26 or 27 of the respective destructing element 20, this arching 28 being essentially analogous to that Fig. 11 represents.

If, in a further embodiment of the invention, the destruction element 20 is made with respect to the truncated pyramid-shaped head 26 ( Fig. 8 ) with its rising edges 29 located between two adjacent lateral surfaces, one of these edges 29 facing the lower edge 16 on the side surface 15 of the fragile protective element 17 and contacted by the arching of the protective element 17, point contact with the destructive element 20 again occurs , which in turn creates an additional burst pressure on the protective element 17. This arch 28 is also largely analogous to that of FIG Fig. 11 represents.

Instead of attaching the destruction element 20 to the inside 19 of the rear wall 5 of the lower housing part 3, there are further possibilities for its rigid attachment. This can be done on the one hand on an inside 30 of the additionally extending vertically on the rear wall 5 and in the Fig. 2 and 3rd peripheral partition 31 shown take place, which is also used in an emergency device 1 with a higher degree of protection, such as sealing ( Fig. 2 and 3rd ).

If, on the other hand, these additional partition walls 31 are not required, the destruction part 20, not shown, is attached to the inside 32 of the circumferential side wall 6 of the lower housing part 3 ( Fig. 2 and 3rd ).

The shaft 21 of the destruction element 20 is formed from two shaft parts, namely the lower shaft part 21a and the upper shaft part 21b, the upper shaft part 21b is, for example, angled at right angles to the lower shaft part 21a ( Fig. 12 ), and at its free end 22 facing the protective element 17, again a frustoconical head 23 ( Fig. 5 and 4th ) or conical head, a spherical segment-shaped head 24 ( Fig. 6 ) or spherical head, an ellipsoid segment-shaped head 25 ( Fig. 7 ) or ellipsoidal head, a truncated pyramid head 26 ( Fig. 8 ) or pyramid-shaped head or ultimately a head 27 equipped in the direction of the inside 10 of the closed housing door 4 rising head ( 9 and 10 ) is provided.

In a further possible embodiment of the invention according to the Fig. 13 and 14 instead of the rigid attachment of the destruction element 20 to the inside 19 of the rear wall 5 in the lower housing part 3, the destruction element 20 is again rigid, but is now arranged on the inside 10 of the housing door 4. At least one destruction element 20 is in the middle ( Fig. 13 and 15 ) or provided off-center on the relevant side surface 15 of the fragile protective element 17. This destruction element 20 also consists of a shaft 21, at the free end 22 of which a head 33 ( Fig. 16 ) is provided, on the underside of which an inclined surface that rises in the direction of the lower housing part 3 and runs parallel to the edge 16 of the fragile protective element 17 extends such that it engages over the area of the relevant side surface 15 with its lower edge 16 of the fragile protective element 17 in a hook-like manner. In the rest position of the emergency device 1, the destruction element 20 is in turn only at a slight distance, but does not touch the lower edge 16 of the fragile protective element 17.

The includes in the Fig. 14 illustrated embodiment of the invention, in turn, a preferred central arrangement of the destruction element 20 in the region of the affected side surface 15 of the protective element 17 on the housing door 4 and its configuration with the rising inclined surface provided on the head 33. This inclined surface is aligned parallel to the lower edge 16 of the fragile protective element 17.

If the protective element 17 which is initially required for an intended alarm triggering is then initiated, if necessary by appropriate aids, the arching of the protective element 17 which subsequently arises leads to a line contact with the destructive element 20, the protective element 17 being destroyed by the lateral burst pressure which occurs is subjected. Otherwise, the structure and mode of operation of this embodiment variant are essentially the same already described above with reference to the frustoconical head 23 of the destruction element 20. This arch 28 is also essentially analogous to that of FIG Fig. 11 represents.

Around the recess 11 on the inside 10 of the housing door 4, an elastic seal, not shown, can be arranged around the edge 13 of the housing door 4, which is connected to the protective element 17. This seal serves to protect the emergency device 1 against water and dust.

The further emergency device 1, not shown in the figures, which appears as a storage box for emergencies and is designed, for example, as an emergency key box, essentially has an analogous structure to the above-described emergency device 1 in the form of a danger detector, in particular a manual fire detector. The only difference is that in the emergency key box, means for hanging, e.g. hooks, the emergency key or means for inserting or inserting the emergency key or the electronic key card are arranged in the housing, while the danger detector in the housing 2 contains a printed circuit board 7 and the like Includes control panel 8 with the switching element 9.
