Definitions

• the invention relates to a safety device for emergency exits on vertical or inclined surfaces of structures.
• DR 11035 describes a lowerable and rotatable platform which is mounted on the facade of a building in front of a window.
• the platform On both sides of the frame of the window, the platform has frame rods which are rotatably mounted on the facade at their lower end.
• the frame rods are connected to a crossbar at their upper ends.
• the platform In the event of an emergency, the platform can be brought into the horizontal position and held in this position by chains from above. Iron crossbars, nets etc. between the frame bars serve as a base for the people to be rescued.
• the US 4,090,585 describes a balcony-like emergency exit in front of a window, which consists of stable floor and railing parts. In the rest position, the emergency exit is folded up and, with the base part rotatably mounted on the building, folded upward onto the vertical surface of the building. In an emergency, the emergency exit is swung down into the horizontal using gravity and unfolded.
• the invention has for its object to provide a safety device for emergency exits, which is essentially invisible in the rest position against vertical or inclined outer surfaces of the building and can be moved to the position of use with simple manipulations before the emergency exit.
• the invention achieves the object by the features mentioned in the characterizing parts of claims 1 and 2. Developments of the invention are characterized in the subclaims.
• the solutions according to claims 1 and 2 together include a safety bar which is pivotally mounted on the building and in the rest position, that is to say when the emergency exit is not used, lies as close as possible to the outer skin of the building below the emergency exit.
• the safety bar which is easily accessible from the emergency exit, is raised and brought into its position of use.
• the supports pivotably mounted on the safety bracket slide freely downwards in the longitudinal direction of the guide rails, exceed the perpendicular to the guide rails in the pivot bearing of the supports and are supported on the lower ends of the guide rails at the stop. In this position, the safety bar with the supports in the guide rails forms a firm, stable frame for a safety device outside the respective building.
• the supports are pivotally mounted on the structure and the other ends of the supports are freely movable in the longitudinal direction on the legs of the safety bar, so that in the rest position they are parallel to the ends of the legs of the safety bar.
• the supports slide, in an equivalent manner to the solution according to claim 1, through the heavy weight of the supports or by means of restraint on the legs up to the stops in the region of the corners of the safety bar. In this Position is also a stable safety device created around the emergency exit.
• both solution variants have a safety net which extends at least between the entire crosspiece of the safety bracket and the building.
• the safety bar itself does not offer sufficient safety, since people who use the emergency exit could slip under it, the safety net closes the entire area of the emergency exit with high effectiveness.
• the safety network is preferably folded up in a corresponding receptacle on the surface of the building below the emergency exit.
• the people in need can move to the emergency exit outside the building with a high degree of security and stop there. This ensures in a first stage that the people can be supplied with fresh air at a safe position. In the second stage, people are picked up by emergency workers from the emergency exit, or they can get themselves from there using known means, e.g. B. a rope ladder, bring to the floor.
• known means e.g. B. a rope ladder
• the invention has the essential advantage that the respective persons are secured against falling on the emergency exit. Compared to emergency rescues via windows or balustrades, there is a significant increase in security achieved and the recovery is accelerated significantly.
• the specific implementation of the safety network depends in particular on the local conditions on the specific building. In any case, there must be the possibility that the people below the fixed safety bar can pass through the area of the safety net. That can e.g. B. always be a free page or there can be easily detachable connections within the safety network, which are opened in particular by helpers, so that the people can be freed through the safety network.
• the invention can be further improved with additional features.
• it can be advantageous to equip the safety bar with opening aids so that it can be easily lifted in the event of danger.
• This can in particular be counterweights, mechanical springs or gas springs.
• the safety device in the rest position can be arranged or covered completely or partially in the surface of the building or covered.
• FIG. 1 shows a safety device in the rest position on a dormer window.
• FIG. 2 shows a safety device in a safety position on an open roof tilt window.
• FIG. 3 shows a safety device in a safety position on a vertical house wall.
• the safety device according to the invention is shown in the rest position on a dormer.
• the building is a listed building, for example, and the artistically valuable roof dome 1 on the roof 2, which is not shown here, should be able to be used as an emergency exit 3.
• the safety bar 4 and the emergency exit 5 can be seen in FIG. The further details are described in more detail in the examples below.
• FIG. 1 shows clearly that the safety device according to the invention is barely perceptible in its rest position.
• a tilting roof window 6 is shown on an inclined roof 2, which is also intended to serve as an emergency exit.
• an emergency exit 5 is located outside in front of the roof tilt window 6.
• a safety device according to the invention is provided to secure the people who use the emergency exit 5.
• the safety bar 4 encloses with its two legs 9 the entire width of the roof tilt window 6.
• the safety bar 4 is closed by the crossbar 10.
• a support 12 is pivotably arranged on the legs 9.
• each support 12 has a carriage 13 which is freely movable in the longitudinal axis within the guide rail 7.
• the drives 13 of the supports 12 are parallel to the ends of the legs 9.
• the drives 13 roll freely downwards in the guide rail 7 up to a stop 15.
• This stop is located below the vertical 16 to the guide rail 7, which goes through the pivot bearing 11.
• the safety bar 4 is stably supported on the supports 12 and forms a secure frame around the entire emergency exit.
• the legs of the safety bracket 4 are in the rest position of the safety device parallel to the guide rails 7 close to the surface of the roof 2 and are optically in no way disturbing.
• the roof tilt window 6 is opened and the safety bar 4 is pulled up.
• the basket-like safety device is installed directly in front of the emergency exit.
• people at risk are able to step out of the interior of the building.
• emergency responders in particular the fire brigade, enable the people to be rescued safely by the safety device.
• the people on the emergency exit 5 on the sloping roof 2 are against falling secured. No windows, parapets or similar have to be overcome during the following salvages, the emergency exit can be entered with great certainty.
• the connecting bolts in the front part of the safety net 17 are opened by the emergency workers and the people in need can safely leave the emergency exit according to the circumstances.
• a security device according to the invention is shown on a vertical house wall.
• Such safety devices can be retrofitted from newer safety regulations, in particular to older high-rise buildings.
• the safety device is mounted on a house wall 20 in front of a window 19.
• window 19 is also intended to serve as an emergency exit.
• the apparatus ⁇ security device has a safety bracket 21, the two legs 22 is pivotally mounted in two pivot bearings 23 on the house wall 20. Beneath the window 19 are in the vertical plane of the legs 22 of the safety bracket 21 in a pivot bearing 24 each pivotally mounted supports 25. The upper ends of the supports 25 opposite the pivot bearing 24 are equipped with a sliding block 26 which is freely displaceable in the longitudinal direction within the legs 22. In the corner area of the safety bar there are suitable stops for the sliding blocks.
• a safety net 29 is located between the crosspiece 27 of the safety bracket 21 and the front edge of the emergency exit 28.
• the emergency exit 28 is pivotably mounted in a pivot bearing 30 on the house wall 20 and is secured via two lateral holding chains 31.
• the safety bar 21 is designed so that the window 19 is not covered, ie that there is no obstruction.
• the security direction can also be arranged recessed within the masonry of the house wall 20 in such a way that the safety device is largely invisible in the rest position.
• the window 19 is opened and the easily accessible crossbar 27 of the safety bracket 21 lying below the window opening is pressed forward and upward.
• the supports 25 in their sliding bearing in the legs 22 fall outward to a stop below the perpendicular 32 to the legs 22 in the pivot bearing 24 and support the safety bracket 21.
• the emergency exit 28 falls outwards until the holding chain 31 is tensioned.
• the safety bracket 21 is raised, the safety net 29 also unfolds and the emergency exit 28 can be entered immediately after the safety device has been folded out. The rescue of those in need occurs as in the previous example.
