    专利说明:

    The invention relates to a hinged bulkhead comprising a flap with a horizontal pivot axis which runs along a longitudinal edge of the flap, and at least one float for erecting the flap from a lying position to an erected position by pivoting the flap about the pivot axis.
    Such a hinged bulkhead is known for example from DE 10 2014 114 057 A1. Such a hinged bulkhead can be used, for example, to protect parts of the building against the ingress of surface water. Furthermore, such a hinged bulkhead can be used to prevent contamination of the environment in the event of an unintentional escape of liquid substances. In particular, such a hinged bulkhead can be used in conjunction with automatic extinguishing systems in order to prevent the extinguishing water from escaping and, if necessary, to also channel its drainage. Due to the float actuation, the hinged bulkhead is automatically erected if necessary and thus prevents liquids from penetrating. The hinged bulkhead is completely self-sufficient, i.e. Operable independently of external energy.
    In the lying position, however, the flap of the hinged bulkhead closes flush with the floor so that it is not an obstacle and can therefore be attached in particular in the area of passages and driveways. The float is sunk in a trough or tub in the floor so that the hinged bulkhead is barely noticeable from the outside in the non-activated state in which the flap is in a lying position. This allows the hinged bulkhead to be installed inconspicuously on objects.
    A conventional hinged bulkhead with a flap with a horizontal pivot axis is also known from GB 2 457 463 A1. In this case, a float is arranged within a cavity of the flap. This cavity is flooded when the water is present, so that the float can rise and the height of the flap can further increase. The invention is based on the object of showing alternatives to the hinged bulkhead known from DE 10 2014 114 057 A1, taking into account a simple design and maintaining a reliable closing function.
    [0005] This object is achieved by a hinged bulkhead according to patent claim 1. The hinged bulkhead according to the invention is characterized in that the at least one float is attached to an underside of the flap and has a projection which, when the flap is in the lying position, protrudes laterally beyond the longitudinal edge of the flap and in the upright position of the flap is capable of providing a buoyancy force for holding the flap in the erected position.
    This makes it possible to dispense with an articulated coupling linkage between the flap and the at least one float. To ensure a reliable closing function, not just a float is attached to the underside of the flap. Rather, this float is designed and arranged with a projection such that the float can continue to provide sufficient buoyancy in the upright position of the flap to hold the upright flap in this position and to press it against a corresponding seal. This alone enables reliable closing, i.e. an erection of the flap to the actual closed position can be achieved in the erected position.
    [0007] Special embodiments of the invention are the subject of further claims.
    If a very stable design of the flap is required, for example because it is to be driven over by vehicles or has a large span, at least one tension spring acting on the flap can be provided to support the erection. This means that smaller swimmers can also be used. The closing force in the upright position is nevertheless predominantly achieved by the above-mentioned projection of the float, which remains immersed in liquid when it is flooded.
    Preferably, any tension spring that is present is housed in a space which is located below the flap in a lying position. The tension spring is therefore not visible from the outside when the flap is lying down. Ideally, it remains within the said room even when the flap is upright, so that it does not create a trip hazard.
    As already mentioned, the flap can be designed to be driven over by motor vehicles. For this purpose, the flap can have a thin-walled plate, for example, which is stiffened on its underside by struts in order to save weight.
    In a further advantageous embodiment of the invention, the at least one float rests directly against the underside of the flap.
    If necessary, a plurality of floats can be arranged between the struts and attached directly to the underside of the plate.
    In a further advantageous embodiment of the invention, an automatically extendable warning device is arranged below the flap, which is held down by the flap in the lying position and is released when the flap is erected, so that the warning device by a spring and / or a float actuated extends. The warning device can reliably warn people of falling into a flooded trough in front of the erected flap, since the warning device automatically lags behind the erecting of the flap.
    The warning device can, for example, have a column or a board which is held in a vertical guide device and depending on the design, spring-actuated and / or float-actuated when the liquid level rises, extends in the vertical direction out of the trough.
    In a further advantageous embodiment of the invention, the flap is linked to a horizontal threshold along its pivot axis via a waterproof hinge. The watertight hinge combines the function of swiveling the flap and its bottom-side sealing in the upright position. The watertight hinge can be designed, for example, as a strip made of an elastomer material, which is connected in a sealed manner to the flap as well as to the threshold.
    The projection of the at least one float extends in the lying position of the flap preferably below the threshold.
    In a further advantageous embodiment of the invention, the flap is pressed in the upright position against vertical sealing strips which connect to the watertight hinge, whereby a continuous flexible seal along the bottom longitudinal edge and the side edges of the flap is achieved. As a result, the structure of the hinged bulkhead remains particularly simple.
    As already mentioned, in one embodiment, the flap can bridge a floodable trough in the lying position, the at least one float being received in the trough in the lying position of the flap. The trough can be provided, for example, as a recess on the object side with a correspondingly dimensioned liquid inlet and drain, in which the hinged bulkhead is mounted. It is important to ensure that liquid can build up inside the trough so that the swimmer can float up to operate the flap. It is also possible to provide a trough in the form of a trough on which the hinged partition is preassembled in the workshop so that the tub can then be installed together with the hinged partition in a recess on the object side.
    In a further advantageous embodiment of the invention it is provided that the at least one float tapers in a wedge shape towards the erectable longitudinal edge of the flap. This favors a quick erecting of the flap with lower lifting forces by reducing the restoring torque of the flap directed into the lying position.
    The hinged bulkhead explained above is characterized by a particularly simple structure and a reliable closing function. Separate counterweights or pre-tensioned spring mechanisms triggered by float actuation for erecting the flap, which would be prone to failure, are not required here. Such mechanisms would have to be precisely balanced on the one hand and would be relatively complex mechanically on the other hand. If the mechanism were to malfunction, the protective function would be endangered. If springs are used to support the erection of the flap, their function is primarily to reduce the dimensions of the at least one float. A trigger mechanism is not required for this. The flap is raised from the lying position to the fully raised position by actuating the float.
    [0021] The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing. The drawing shows in:<tb> <SEP> Figure 1 is a cross-sectional view of a first embodiment of a hinged bulkhead according to the invention in a lying position,<tb> <SEP> Figure 2 shows a cross-sectional view of the hinged bulkhead according to the first embodiment in the upright position,<tb> <SEP> Figure 3 shows a further view of the hinged bulkhead according to the first embodiment in the upright position, and in<tb> <SEP> FIG. 4 shows a cross-sectional view of a second exemplary embodiment of a hinged bulkhead according to the invention in the upright position.
    The first embodiment shown in Figures 1 to 3 shows a fully automatic hinged bulkhead 10 for protection against the ingress of liquid, which is arranged in front of a vertical opening 1 of a building 2 or the like to be blocked against the passage of the liquid. The hinged partition 10 is let into a recess 3 in the floor 4 in front of the vertical opening 1, so that in its open position shown in FIG. 1 it is essentially flush with the surface 5 of the floor 4. As a result, the hinged bulkhead 10 does not constitute an obstacle in its open position. Rather, it can be designed to be accessible or driven over by motor vehicles. Installation is usually carried out in a predominantly horizontal floor surface 5. Installation in slightly inclined surfaces, such as at underground car park entrances, is also possible.
    The hinged bulkhead 10 initially comprises a flap 11 with a horizontal pivot axis A which runs along a longitudinal edge 12 of the flap 11.
    Via a hinge 13, which is preferably designed to be watertight, the flap 11 is pivotably articulated on a horizontal threshold 14 installed in a stationary manner in the vertical opening 1. The hinge 13 can be formed, for example, by a strip 15 made of elastomer material which, as already described in DE 10 2014 114 057 A1, is fastened in a sealing manner to the flap 11 and to the threshold 14. The strip 15 made of elastomer material also represents the bottom seal of the flap 11.
    In a modification of the illustrated embodiment, the function of the pivotability of the flap 11 and the function of the bottom seal can, however, also be separated from one another. Instead of a hinge 13 in the form of a strip 15 made of elastomer material, other types of joints can also be used.
    Furthermore, the hinged bulkhead 10 comprises at least one float 16 for erecting the flap 11 from a lying position shown in Figure 1 into an upright position shown in Figures 2 and 3 by pivoting the flap 11 about the pivot axis A. In Figure 3 is the float 16 is shown as a continuous unit. However, several separate floats 16 can also be provided.
    In the present case, the at least one float 16 is attached to an underside 17 of the flap 11 and pivots with the flap 11. In particular, the at least one float 16 can be arranged in direct contact with the flap 11. For example, it is possible to glue a float 16 to the underside 17 of the flap 11. The float 16 is designed in such a way that it floats in liquids, so that the buoyancy force provided by it is used to raise the flap 11 from the lying position according to FIG. 1 to the upright position according to FIGS. 2 and 3.
    If the flap 11 is stiffened on its underside 17 by struts not shown in detail here, the float or swimmers 16 can extend into spaces located between the struts.
    According to the invention, the at least one float 16 has a projection 18 which, in the lying position of the flap 11 below the pivot axis A, protrudes laterally beyond the longitudinal edge 12 of the flap 11 and is suitable in the upright position of the flap 11, a buoyancy force for holding the flap 11 in the erected position. As can be seen from FIG. 1, the projection 18 of the float 16 extends in the lying position of the flap 11 to below the horizontal threshold 14. The projection of the projection 18 over the pivot axis A is denoted by s in FIGS. 1 and 2.
    The flap 11 bridges a floodable trough 20 in the lying position. The trough 20 is preferably designed in such a way as to completely accommodate the at least one float 16 in the lying position of the flap 11. On the trough 20 there is a liquid inlet which, for example, can be connected to a collecting channel 21 upstream of the flap 11, as well as a bottom-side outlet 22. The liquid inlet and the outlet 22 and the volume of the trough 20 are coordinated with one another in such a way that one In the event of a sudden liquid event, sufficient liquid is dammed up in the trough 20 in order to allow the float 16 to float up and thus to cause the flap 11 to be erected by pivoting the same about the pivot axis A. The buoyancy of the totality of the floats 16 is matched to the weight of the flap 11 in such a way that it can be raised to the fully upright position in order to press the flap 11 against vertical sealing strips 30 arranged on the object side, which are preferably on the watertight hinge 13 connect. The projection 18 of the at least one float 16 remains immersed in the liquid within the trough 20 and provides a corresponding buoyancy force.
    If the liquid level in the trough 20 falls again, the flap 11 returns to its lying position.
    The erection of the flap 11 and the return to the lying position take place completely automatically. No intervention by operators is required here. Likewise, the hinged bulkhead 10 manages without any external energy. It works completely independently and thus offers a high level of protection against the undesired penetration of liquids. Due to its simple structure, it is also not susceptible to interference, which results in a high level of reliability, especially in the automatic locking function.
    Small amounts of liquid, as they occur, for example, in normal rainfall, run over the bottom drain 22 so quickly that no unwanted in this case even slight lifting of the flap 11 takes place, which lead to an obstacle in a walkable or traversable passage would.
    In one embodiment, the at least one float 16 can have a shape that tapers in a wedge shape towards the erectable longitudinal edge of the flap 11 in order to reduce the restoring torques caused by the float 16 when erecting. However, it is also possible, in particular when using hollow-body floats, to use other shapes for the float 16, for example a shape which largely fills the cross section of the trough 20 in FIGS.
    In order to reduce the dimensions of the at least one float 16, at least one tension spring 19 can optionally act on the flap 11, which tension spring supports an erecting of the flap 11.
    The tension spring 40 can, as shown in Figures 1 and 2, be accommodated in a space which is located below the flap 11 in a lying position. The tension spring 40 is consequently not visible from the outside when the flap 11 is lying down.
    In the present case, for the connection of the tension spring 40 to the flap 11, a lever arm 19 is arranged which protrudes from the underside 17 of the flap into the trough 20. One end of the tension spring 40 is connected to the free end of the lever arm 19 and its other end is fixed, for example, to an inside wall section of the trough 20 or to a support within the trough 20. As can be seen from FIGS. 1 and 2, the tension spring 40 is tensioned when the flap 11 is lying in order to support the erection of the flap 11 when the at least one float 16 floats up. FIG. 2 shows the tension spring 40 with the flap 11 erected in a less strongly tensioned or relaxed state. The lever arm 19 and the tension spring 40 remain within the trough 20.
    Furthermore, an automatically extendable warning device 50 can be arranged below the flap 11 on the hinged bulkhead 11, which is intended to prevent people from falling into the flooded and thus difficult to see trough 20 when the flap 11 is upright. The extendable warning device 50 is designed and arranged such that it is held down by the flap 11 in a lying position and is only released when the flap 11 is erected. After it has been released, the warning device 50 extends automatically, for example actuated by a spring and / or its own float.
    The warning device 50 can for example have a column or a panel 51 which is held in a vertical guide device 52 and depending on the design, spring-actuated and / or float-actuated when the liquid level rises, extends out of the trough 20 in the vertical direction. The warning device 50 thus follows the flap 11. When the flap 11 is lowered, it pushes or pushes the warning device 50 back into its lowered position. If necessary, the warning device 50 can also be retracted and / or extended via a cable mechanism or the like controlled by the flap 11.
    In the embodiment variant shown in Figures 1 and 2, the column or panel 51 can be designed directly as a float.
    As Figure 4 shows in comparison to Figures 1 to 3, the warning device 50 shown is optional, i.e. a hinged bulkhead 10 can also be installed without one. The warning device 50 is also suitable for retrofitting existing hinged bulkheads, since this takes up little space within the trough 20.
    In the figures 3 a seal of the flap 11 is shown in an upright position against a wall surface of a building 2 by way of example. As a modification of this, the seal can also take place against a pre-built stop which is provided with the vertical sealing strips 30 accordingly. The stop can be designed, for example, as a metal stop with a seal, which is mounted on a building wall or the like. It is also possible to provide a stop on a separately erected column. In addition, several hinged bulkheads can be chained next to one another and use common stops if necessary.
    The invention has been explained in more detail with reference to embodiments and further modifications in order to show possible ways of carrying out the invention. Technical individual features, which were explained above in the context of further individual features, can also be implemented independently of these and in combination with further individual features, even if this is not expressly described, as long as this is technically possible. The invention is therefore expressly not limited to the specifically described exemplary embodiments and modifications, but rather encompasses all of the configurations defined by the patent claims.
