Description
Device for sealing off rooms
The invention refers to a device for closing or sealing off an opening of an room against a fluid flowing into the room or out from the room, having a flap which is substantially pivotable about a horizontal axis from a first position releasing the opening to a second position, wherein, in each case, at least one frame element is arranged laterally adjacent to one of the two longitudinal ends of the flap and a stationary seal is provided which, in the arrangement of the flap in its second position, in which the flap at least partially closes the opening of the room, is arranged, at least in sections, in a sealing manner between the flap and frame element, wherein a semi-stationary seal is provided on at least one longitudinal end of the flap in each case, of which a first side edge is fixed fluid-tightly to the corresponding longitudinal end of the flap and a second side edge to the corresponding frame element, such that during the movement of the flap from its first position to the second position, the first side edge moves towards the second side edge and a lateral influx of fluid is prevented, and wherein a third side edge of the respective semi-stationary seal lies opposite the first side edge.
The use of a flap or a bulkhead to seal off openings, designed as doors or passages, of a room, such as of a workshop or warehouse, is known from the prior art. Once a fluid spreads on the floor in front of the opening of the room, the flap ought to close and seal off the opening of the room, so that adjacent rooms or the surroundings of the room do not come into contact with the fluid or are not inundated or flooded by the fluid. It should therefore be ensured, by means of the flap, that no fluid flows out from a room or into it. The fluid can be a liquid such as water, chemicals, oils, or mixtures thereof. Such liquids or liquid mixtures arise particularly during heavy rainfall or when extinguishing water is pumped into the room by the fire brigade or sprinkler systems. The flap ought to close openings effectively and reliably and protect the rooms behind it from flooding.
Within the context of the invention, a room is understood to mean not just a building or part of a building such as a garage, a house entrance, a workshop or a warehouse, but also areas delimited by boundaries, for example wails, that have at least one opening, for example in the form of a passageway which must be dosed as needed.
An arrangement of the type mentioned above is known, for example, from GB 2 403 254 A.
Furthermore, an arrangement is known from EP 0 754 822 A2, in which a device for sealing off a room is described. The device comprises a flap that is pivotable about a substantially horizontal axis which can be folded up by a drive from a recess provided in a floor of the room, in response to a fluid entering the recess. This flap or this flap partition is designed as a floating body. The drive comprises at least one weight which can be moved substantially vertically, and which is connected via a gear to the axis, and causes a torque around the axis, which is greater than a torque acting around the axis by the weight of the flap when the flap has been deflected from its substantially horizontal position in the recess by the fluid entering into the recess.
The flap for closing an opening is pivoted from a first position, in which it is arranged in the recess, to a second position, in which it at least partially makes contact with a stationary seal which is mounted on a frame element. The stationary seal ought to ensure that no fluid can flow through the opening into the room or out from the room. A stationary seal is in this case understood to mean a seal that is mounted in a fixed manner, for example on the frame element or on the flap, and does not change position and in particular its shape during the pivoting movement of the flap. However, especially during the pivoting movement of the flap into the second position, there is a temporary risk that fluid may laterally pass between the frame element and the flap through the opening.
From WO 2007/057202 Al, a device is known which is used for sealing off a room against a fluid flowing into the room or out from the room, wherein the fluid can particularly be a combustible liquid. The device comprises a flap which can be pivoted from a first position to a second position around an axis, frame elements and at least one seal which is provided at one edge running transversely to the axis and is connected to the flap and the frame element. To take account of the great heat generation in case of fire, screening means are provided which surround the seal. In this way, the sealing function is ensured even with large heat generations where the problem was otherwise that the components of the device exhibited different thermal behaviour and the sealing function could not be ensured or could only be ensured to a reduced degree. However, this device has the disadvantage of a plurality of components to be installed. Another disadvantage is that the known device additionally occupies a large amount of installation space in the area in front of and to the side of the opening of the room when the opening is released and the flap is arranged in the first position, in which the flap assumes a horizontal position. In this position, or stance, the seal is expanded at the side edge of the opening and blocks the lateral area adjacent to the opening, meaning the seal constitutes an obstacle to be avoided or circumvented.
The object of the invention is to provide a solution that provides, via a simple design and cost-effectively, a simplified and improved arrangement for closing an opening of a room against a fluid flowing into the room or out from the room.
In an arrangement of the type mentioned above, this object is achieved in that the length of the first side edge attached to the flap is shorter than the height of the flap, in that the third side edge is designed to be dimensionally stable and is pivotably connected, at a corner formed by the second side edge and the third side edge, via a respective hinge element, to the associated frame element, and in that a blocking element coupled to the movement of the flap is provided which, in the first position of the flap, blocks a movement of the third side edge towards the opening and which, on movement of the flap towards the second position, enables the movement of the third side edge towards the opening.
Advantageous and expedient configurations and further developments of the invention are found in the corresponding dependent claims.
The invention provides an option which improves the sealing function of the arrangement via a simple design and cost-effectively, said arrangement requiring very few components compared to the prior art, meaning the arrangement as a whole is less susceptible to interference. At the same time, the installation space or the space occupied by the semi-stationary seal in the first position of the flap is substantially reduced, so that the semi-stationary seal is no longer an obstacle for trucks or forklifts in the first position of the flap. The maximum length of the first side edge of the semi-stationary seal is defined by the height of the flap. Within the meaning of the invention, "semi-stationary seal" is understood to mean a seal in which at least one side edge is attached in a stationary manner and at least one other side edge moves the flap on movement from the first to the second position of the flap. In the arrangement according to the invention, the semi-stationary seal does not constitute any obstacle to the daily operating procedure. In the folded state, i.e. in the first position of the flap, the flap is flush with the floor in front of the opening to be secured. Due to a solid construction, the flap can be run over by vehicles without any problems. The semi-stationary seal can be designed as a flexible film made of a plastic such as polytetrafluoroethylene (PTFE), wherein the invention provides that a third side edge of the relevant semi-stationary seal lies opposite the first side edge, wherein the third side edge is designed to be dimensionally stable and is pivotably connected, at a corner formed by the second side edge and the third side edge, via a respective hinge element to the associated frame element. The third side edge runs, in the first position of the flap, horizontally and parallel to the flap so that the semi-stationary seal embodied as a flexible film is stretched in the first position of the flap between the first and third side edge. For the purpose of locking the semi-stationary seal in the first position of the flap, it is advantageous if a blocking element coupled to the movement of the flap is provided which, in the first position of the flap, blocks a movement of the third side edge towards the opening and which, on movement of the flap towards the second position, enables the movement of the third side edge towards the opening. In the first position of the flap, the third side edge can optionally be pre-stressed towards the opening, In other words, it is desirable for the pivoting movement of the flap to enable the folding of the hinge elements or at least of the third side edge, i.e. for a pivoting movement of the hinge elements to be blocked in the horizontal, first position of the flap.
The stationary seal can be embodied as a ring seal which extends in a vertical direction and is attached to the respective frame element. For the purposes of saving material, the invention provides in a configuration that, in the second position, a respective longitudinal end of the flap lies in against both the semi-stationary seal and the stationary seal, closing the opening along the height of the flap. In the second position of the flap, the semi-stationary seal thus seals a section near the floor of the longitudinal end of the flap, whereas the stationary seal seals the remaining section which is distant from the floor, so that the flap lies, in the second position, in a sealing manner along its entire height on the stationary and semi-stationary seal.
Alternatively, the semi-stationary seal can also be used only to ensure the lateral sealing function, i.e., prevention of lateral inflow, during the movement of the flap between the first and second position, where the invention provides, for this purpose, that in the second position, a respective longitudinal end of the flap only lies against the stationary seal, closing the opening in a sealing manner along the height of the flap.
In design terms, a particularly favourable way to avoid lateral inflow of fluid through the opening is to design the semi-stationary seal in quadrangular form and so that it, at least in the first position of the flap on a respective corner area which is formed by flap and frame element, spreads out extensively and extends as a quadrangle. The semi-stationary seal thus covers, in the first position of the flap and for a part of the movement of the flap from the first position towards the second position, a quadrangular area on the side edge of the flap.
In a further embodiment, the invention provides that the hinge element is designed to enable a pivoting movement of the third side edge, which is designed to be dimensionally stable, exclusively towards the opening of the room. As a result, the hinge element prevents unwanted movement of the third side edge away from the opening.
Although the pressure of the fluid which impacts on the stationary seal ensures a movement of the third side edge towards the opening of the room, it is advantageous if the third side edge is inclined towards the opening of the room at an angle of between 2° and 15° in the first position of the flap. As the third side edge is engaged in the direction of the opening, the direction of movement of the third side edge is defined during the movement of the flap from the first to the second position.
Similarly, the invention provides in a configuration that a fourth side edge of the respective semi-stationary seal lies opposite the second side edge, said fourth side edge being designed to be dimensionally stable and being pivotably connected, at a corner formed by the first side edge and the fourth side edge, via a respective hinge element to the flap.
In order to prevent an undesired pivoting movement of the fourth side edge as above, the invention provides in a further configuration that the hinge element is designed to enable a pivoting movement of the fourth side edge, which is designed to be dimensionally stable, exclusively towards the door.
In this regard, it is then also advantageous for the fourth side edge, as in the case of the third side edge, if the fourth side edge is inclined towards the flap at an angle of between 2° and 15° in the first position of the flap.
With respect to a cost-effective and simple manufacture of the arrangement for closing an opening of a room, the invention provides in a further development that a respective dimensionally stable side edge is designed as a strip, to which the corresponding side edge of the semi-stationary seal element is attached and which is pivotably mounted on the end of the corresponding hinge element.
To prevent the semi-stationary seal from collapsing or folding together in the first position of the flap, the invention provides in a configuration that the semi-stationary seal is locked in the first position of the flap, in which it spreads extensively and extends in quadrangular form over a corner area defined between the flap and the frame element. A simple design option is given in a configuration of the invention in that the blocking element is designed as a movement-coupled locking hook connected with the flap, which engages with the third side edge in the first position of the flap and holds the side edge in a fixed manner, wherein the locking hook is connected with the flap via a movement converter converting the movement of the valve from the first position towards the second position into a movement releasing the third side edge of the locking hook. In other words, the movement-coupled connection between the flap and the locking hook can be designed as a connection disengaging the locking hook from the third side edge on movement of the flap from the first position towards the second position.
As an alternative to the locking hook, it is also favourable in design terms if the blocking element is designed as an angle element which interacts with the third side edge and can be rotated towards the flap, of which a first leg is connected to the semi-stationary seal and of which a second leg protrudes beyond a longitudinal end of the flap, wherein the angle element, in the first position of the flap, lies against a stop blocking a rotational movement of the angle element and arranged in a fixed manner in a stop position and is arranged, on movement of the flap, from the first position towards the second position from the stop position into a release position. In other words, the angle element can be attached to the dimensionally stable fourth side edge, wherein a leg of the angle element protrudes beyond a longitudinal end of the flap, wherein the angle element can be rotated with the hinge element of the fourth side edge and, in the first position of the flap, lies against a stop blocking a rotational movement of the angle element, and wherein the movement of the flap from the first position towards the second position releases the angle element from the stop.
The locking hook and the angle element hold, in the first position of the flap, the third side edge and thus the semi-stationary seal in their stretched state, in which it spreads extensively and extends in quadrangular form over a corner area defined between the flap and frame element. A fixing of the semi-stationary seal is particularly necessary when, in a configuration of the invention, the third side edge is pre-stressed towards the opening and/or the fourth side edge is pre-stressed towards the flap. As soon as the flap moves from the first position towards the second position, the fixing of the third side edge or the semi-stationary seal is lifted and the side edges aim, due to the pre-stressing, to move in the appropriate directions so that the semi-stationary seal can fold or collapse according to the position of the flap so as not to impede the pivoting movement of the flap and in order to fulfil the desired sealing function.
As an alternative to the side edges held under pre-stress in the first position of the flap is provided by the invention in an advantageous manner in that the third side edge is connected with the flap via a movement-coupled connection in such a manner that a movement of the flap from the first position towards the second position moves the third side edge towards the opening. This coupling of the movement to combine the semi-stationary seal with the movement of the flap makes a drive for the semi-stationary seal unnecessary, because the movement of the semi-stationary seal, and in particular of its side edges, is coupled with the movement of the flap. This has the advantage that, for a manual pivoting movement of the flap or a pivoting movement of the flap executed by means of a drive, one is not dependent on the hydrostatic pressure of the fluid in order to ensure the folding of the semi-stationary seal.
In a configuration of the invention, there is an option for movement coupling in that the movement-coupled connection between the third side edge and the flap has at least a cable system connecting the third side edge with the axis of the flap, having at least one pulley.
Furthermore, it is particularly advantageous if the length of the first side edge is greater than the length of the second side edge. In other words, it is advantageous if the first side edge extending in a horizontal direction in the first position of the flap is longer than the second side edge extending in a vertical direction in the first position of the flap, because, in this manner, given a small angle of attack of the flap, i.e. even given a slight movement of the flap from the first position towards the second position, a lateral overflow by a fluid across the flap towards the opening is prevented. This is because the further the first side edge of the semi-stationary seal extends along the length of the flap, the higher the semi-stationary seal goes given the same angle of attack of the flap.
As a guideline, it is provided in a further configuration of the invention that the length of the first side edge and/or of the second side edge equals at most half the height of the flap.
So that the semi-stationary seal does not interfere with the sealing function in the second position of the flap, it is finally provided in a configuration of the invention that the semi-stationary seal element has a fold extending obliquely and designed between two opposite side edges on which the semi-stationary seal element folds together on movement from the first to the second position, so that in the second position, the semi-stationary seal element lies folded against the flap and is arranged inside the opening.
So that the flap automatically moves from the first to the second position without a hydraulic, pneumatic or electrical trigger mechanism, it is advantageous in a further development of the invention if the flap is designed as a floating body and, in the first position, is arranged in a recess in front of the opening to be closed, wherein the flap can be folded up by a drive from the first position in response to a fluid entering into the recess. In this case, the drive can have at least one torque means connected to the axis which causes a torque around the axis which is greater than a torque acting around the axis by the weight of the flap when the flap has been deflected from its substantially horizontal position in the recess by the fluid entering into the recess. The torque means can be a weight or a tension spring, as described in EP 0 754 822 A2.
It is understood that the features mentioned above and those still to be explained below can not only be used in the combination indicated in each case but also in other combinations or alone without departing from the scope of the present invention. The scope of the invention is only defined by the claims.

Figures 1 to 14 show an arrangement for closing an opening 1 of a room 2 against a fluid flowing into the room 2 or out from the room 2 or through the opening 1, wherein the fluid can be a liquid (e.g. water), chemicals, oils or mixtures thereof. The arrangement has a pivotably mounted flap 3, by which the opening 1 can be effectively and reliably closed and sealed off, at least in sections, in the area near the floor. The flap 3 is substantially pivotable about a horizontal axis 4 (see Figures 2, 4 and 5), said flap 3 being mounted on one of its two longitudinal edges 5 on the horizontal axis 4. The axis 4 to be considered for the arrangement is mounted on the end of respective frame elements 6 of the arrangement, which are arranged on the side of the opening 1 and next to the two longitudinal ends 7 of the flap 3 and, if necessary, can be attached to a wall 8, in which the opening 1 of the room 2 is designed and delimits the room 2 in sections. It should be noted that in Figures 2, 4 and 5, some parts of the housing of the frame element 6 are not displayed for better illustration of the axis 4. To ensure a fluid-tight joint between the wall 8 and the respective frame elements 6, seals can be inserted between the frame elements 6 and the wall 8.
The flap 3 is installed level with the floor 9 in front of the opening 1, meaning that the flap 3 is inserted into a recess 10 (see, for example, Figures 4 and 5) in the floor 9 and occupies a horizontal position, in which a passage designed as an opening 1 can be walked or driven on. This horizontal stance denotes a first position of the flap 3, in which the flap 3 releases the opening 1 and enables unobstructed passage through the opening. In order to prevent entry of a fluid through the opening 1, the flap 3 can be pivoted about the axis 4 into a second position. Figures 8, 9 and 10 show the flap 3 in its second position, in which the flap 3 at least partially closes and seals off the opening 1 of the room 2, and in particular near the floor 9, whereas in Figure 7, a stance of the flap 3 between the first and the second position is illustrated. In the second position, the opening 1 need not necessarily be closed or sealed off above a certain height, as shown in Figure 9. More important is sealing off the opening 1 at floor level in order to prevent a fluid spreading on the floor 9 from flowing through the opening 1. In the second position, the flap 3 lies at least partially against a stationary seal 11 in a sealing manner, the term "stationary" being understood to mean the fixed position of the stationary seal 11, which is identical in the first and second position of the flap 3 and does not change. Figures 4 and 5 show different configurations of the stationary seal 11, which is embodied in both configurations as a cord seal. The stationary seal 11 is attached to a respective frame element 6 and extends there in a vertical direction. Although, in the embodiment shown in Figure 5, the stationary seal 11 embodied as a cord seal extends at least from the floor 9 along the entire height 12 of the flap 3 in a vertical direction on a respective frame element 6, the stationary seal 11, in the embodiment shown in Figure 4, does not reach the floor 9, but ends at the height of a semi-stationary seal 14, which is provided at the respective longitudinal ends 7 of the flap 3 and ensures fluid-tightness near the floor. The semi-stationary seal 14 is designed as a flexible film made of a plastic such as polytetrafluoroethylene (PTFE) and may additionally have UV-resistant properties.
As can be seen in Figure 3, for example, a first side edge 15 is attached fluid-tightly to the corresponding length 7 of the flap 3, whereas a second side edge 16 is secured fluid-tightly to the corresponding frame element 6. The fluid-tight attachment is embodied such that the first side edge 15 moves, during the movement of the flap 3 from its first position to the second position, towards the second side edge 16, and a lateral influx of fluid is prevented. The lateral influx of fluid is prevented at least in the first position of the flap 3 and for the movement of the flap 3 from the first to the second position. "Semi-stationary seal" is understood in this case to mean a seal wherein at least one side edge (in this case the second side edge 16) is attached in a stationary and thus fixed manner (in this case to the frame element 6) and at least one other side edge (in this case the first side edge 15) moves with the flap during the moving from the first to the second position of the flap 3.
As is apparent from Figure 3, for example, the semi-stationary seal 14 is designed in quadrangular form and spreads extensively, at least in the first position of the flap 3, over a respective corner area 18, which is formed by the flap 3 and frame element 6. This area stretched by the semi-stationary seal 14 in the first position of the flap 3 is additionally delimited by a third side edge 19 and a fourth side edge 20 of the semi-stationary seal 14. Here, the third side edge 19 lies opposite the first side edge 15, whereas the fourth side edge 20 lies opposite the second side edge 16. Both the third side edge 19 and the fourth side edge 20 are designed to be dimensionally stable or inherently stable, and for this purpose, for example, the material in the area of these side edges 19, 20 can be highly compressed accordingly. In the embodiments shown in the Figures, however, the material of the dimensionally stable side edges 19, 20 is not compressed. Rather, a respective dimensionally stable side edge 19, 20 is designed as a strip 21, 22, to which the corresponding side edge 19, 20 of the semi-stationary seal element 14 is attached.
The strip 21 forming the dimensionally stable third side edge 19 is, at a corner 23 formed by the second side edge 16 and the third side edge 19, pivotably connected at the end to the associated frame element 6 via a hinge element 24. Further, the strip 22 forming the dimensionally stable fourth side edge 20 is, at a corner 25 formed by the first side edge 15 and the fourth side edge 20, pivotably connected to the flap 3 via a further hinge element 26. A respective strip 21, 22 is thus pivotably mounted at the end on the corresponding hinge element 24, 26 and connects the semi-stationary seal 14 with the flap 3 and the frame element 6. Here, the strips 21, 22 of the semi-stationary seal 14, together with corresponding sections of the frame element 6 and the flap 3, form a frame-like structure 3 which clamps the semi-stationary seal 14 to a maximum in the first position of the flap 3, so that it seals off the lower corner areas of the opening 1 against a lateral influx of fluid.
The hinge element 24, which pivotably connects the dimensionally stable third side edge 19 and the strip 22 with the frame element 6, can be designed such that upon a movement of the flap 3 from the first position to the second position, the hinge element 24 enables a pivoting movement of the third side edge 19 towards the opening 1 of the room 2 but not in the opposite direction. The other hinge element 26 can be designed in a similar way and only enable a pivoting movement of the fourth side edge 20 towards the flap 3 but not away from the flap 3. Although the pressure of the fluid flowing from the outside towards the opening 1 will generally push the semi-stationary seal 14 towards the flap 3 and the opening 1, it is advantageous if the sealing surface which is stretched by the semi-stationary seal 14 in the first position of the flap 3 is slightly or minimally oriented towards the opening 1 and the flap 3. For this reason, the third side edge 19 is, in the first position of the flap 3, inclined or oriented towards the opening 1 of the room 2 at an angle βι of approximately 9°, whereas the fourth side edge 20 is, in the first position of the flap 3, likewise inclined or oriented towards the flap 3 at an angle βι of approximately 9°. Angles βι and βι of between 2° and 15° are, however, also conceivable.
Furthermore, as is apparent in Figure 6, for example, the length 17 of the first side edge 15 is greater than the length 27 of the second side edge 16. In the embodiment illustrated in the Figures, the semi-stationary seal 14 has a trapezoidal shape in the first position of the flap 3, which implies that the length 29 of the fourth side edge 20 is greater than the length 27 of the second side edge 16. Since the angle yi (see Figure 3) between the first side edge 15 and the second side edge 16 and the angle Y2 (see Figure 3) between the first side edge 15 and the fourth side edge 20 are respectively 90°, these allow, on the one hand, the length 29 of the third side edge 19, and, on the other hand, the angle y3 (see Figure 3)between the second side edge 16 and the third side edge 19, to be determined by calculation. The angle y3 determines the installation position of the hinge element 24, which pivotably holds the corner 23 formed by the second and third side edge 16, 19.
In the illustrated exemplary embodiment, the length 17, 27 of the first and second side edge 15, 16 is approximately identical. If, however, the length 17 of the first side edge 15 is greater than the length 27 of the second side edge 16, that is, when the first side edge 15 extending in a horizontal direction is longer than the second side edge 16 extending in a vertical direction, a lateral overflow via the flap 3 through the opening 1 is prevented even given a small angle of attack of the flap 3. That is because the further the first side edge 15 of the semi-stationary seal 14 extends along the longitudinal end 7 of the flap 3, the higher the semi-stationary seal 14 is raised given the same angle of attack of the flap 3, when the flap 3 moves from the first to the second position. However, because the object of the invention is to keep the installation space in front of the opening as small as possible, it has been found that there is a good compromise between minimal installation space and adequate sealing function when the length 17 of the first side edge 15 equals at most half the height 12 the flap 3. Alternatively, or additionally, the condition applies in this context that the length 27 of the second side edge 16 equals at most half the height 12 of the flap 3.
The semi-stationary seal element 14 has a fold 30 which extends and is designed transversely or obliquely between two opposite side edges. More specifically, the fold 30 runs between the corner 31 formed by the third and fourth side edge 19, 20 and the corner 32 formed by the first and second side edge 15, 16. At the fold or fold line 30, the semi-stationary seal element 14 is folded together on movement of the flap 3 from the first to the second position, as shown in Figure 7 for a position of the flap 3 between the first and second position. The semi-stationary seal 14 is folded together or collapsed in such a manner that the semi-stationary seal element 14 lies folded together against the flap 3 in the second position of the flap 3 and is arranged inside the opening 1, as shown in Figures 8 and 10. In the second position of the flap 3, the first side edge 15 lies against the second side edge 16 and the third side edge 19 lies against the fourth side edge 20 and the two strips 21 and 22 lie against each other. It should be noted that the fold 30 is me rely optional and can be omitted without worsening the folding of the semi-stationary seal 14.
In the second position of the flap 3, in the embodiment illustrated in Figure 5, only the stationary seal 11 seals because it interacts solely with the flap 3. The semi-stationary seal 14 is arranged in this embodiment between the stationary seal 11 and the opening 1 and counteracts a lateral inflow until the flap 3 is arranged in the second position. In the second position of the flap 3, only the stationary seal 11 seals, as this interacts solely with the flap 3. In the second position of the flap 3, a respective longitudinal end 7 of the flap 3 thus lies exclusively against the stationary seal 11, closing the opening 1 in a sealing manner along the entire height 12 of the flap 3.
In contrast, in the embodiment illustrated in Figure 4, the stationary seal 11 and the semi-stationary seal 14 seal together in the second position of the flap 3, since both seals 11 and 14 interact with the flap in sections in a sealing manner along the height of the flap 3. More specifically, in the second position of the flap 3, the semi-stationary seal 14 interacts in a sealing manner together with a lower section of the flap 3 relative to its height 12, whereas the stationary seal 11 interacts in a sealing manner with the section of the flap 3 situated above said seal. Thus, in the second position of the flap 3, the semi-stationary seal 14 seals a section of the longitudinal end 7 of the flap 3, whereas the stationary seal 11 seals the remaining section of the longitudinal end 7 of the flap 3, so that, in the second position along its entire height 12, the flap 3 lies in a sealing manner in sections against the stationary and semi-stationary seal 11, 14. A common feature of both embodiments shown in Figures 4 and 5 is, however, that the length 17 of the first side edge 15, which is attached to the flap 3, is shorter than the height 12 of the flap 3. Another commonality between the two embodiments is that the flap 3 is designed as a floating body and, in the first position, is arranged in the recess 10 designed in front of the opening 1 to be closed, wherein the flap 3 can be folded up from the first position by a drive 33 shown in Figure 9 in response to a fluid entering into the recess 10, said drive being designed as a spring element. The spring element and the drive 33 are connected via a gear to the axis 4, and cause a torque around the axis 4 which is greater than a torque acting around the axis 4 by the weight of the flap 3 when the flap 3 has been deflected from its substantially horizontal position in the recess 10 by the fluid entering info the recess 10, i.e. the first position, towards the second position. The flap 3 is raised by the fluid entering the recess 10 due to buoyancy and then folded and pivoted into a vertical position by the drive 33 by means of a spring force and pressed against the stationary and, where applicable, semi-stationary seal 11 and 14. The flap 3 thus rotates automatically into a vertical position and can be pushed by hand back into the horizontal first position. Alternatively, the flap 3 can be raised exclusively by the buoyancy of the fluid entering into the recess 10, the drive 33 designed as a spring element being only used for the purpose of compensating for the weight of the flap 3 and holding it in the position it reaches due to the buoyancy. This prevents a sudden and, particularly, complete upward pivoting movement of the flap 3, thereby increasing occupational safety.
Figures 11, 12 and 13 further demonstrate different mechanisms for the semi-stationary seal 14 so that it is either fixed in a position extensively spread in the first position of the flap 3 or, however, so that it is folded in on movement of the flap 3 from the first towards the second position of the flap 3. In other words, it would be advantageous if the pivoting movement of the flap 3 enabled the folding of the hinge elements 24 and 26 or at least of the third side edge 19, i.e. if a pivoting movement of the hinge elements 24, 26 were blocked in the horizontal, first position of the flap 3.
Figures 11 and 12 show a blocking element 40 of the arrangement. The blocking element 40 is coupled with the movement of the flap 3. In the first position of the flap 3 illustrated in Figures 11 and 12, the blocking element 40 blocks a movement of the third side edge 19 towards the opening 1, which, with reference to Figures 11 and 12, is arranged behind the flap 3. In contrast, the blocking element 40 is designed such that upon a movement of the flap 3 from the first position towards the second position, the fixing or movement blocking of the third side edge 19 is cancelled and the third side edge 19 can move towards opening 1. This locking of the third side edge 19 in the case of an extensively spreading semi-stationary seal 14 prevents the semi-stationary seal 14 from moving undesirably into the area of the opening 1 and obstructs it at least partially when the flap 3 is in the first position.
According to a first embodiment according to Figure 11, the blocking element 40 is designed as an angle element 41 which can be rotated towards the flap 3 about a pivot point 42. The angle element 41 acts via a type of reinforcement strip 43 which extends along the fourth side edge 20, together with the third side edge 19, that is, when the reinforcement strip 43 extends in a vertical position relative to the flap 3 and is held in this position, the third side edge 19 can inevitably not move towards the opening 1. The L-shaped angle element 41 further comprises a first leg 44 which is connected to the semi-stationary seal 14 and to the reinforcement strip 43 attached to the fourth side edge 20, and a second leg 45, which protrudes beyond the longitudinal end 7 of the flap 3. In the first position of the flap 3, as illustrated in Figure 11, the angle element 41 lies against a stop 46 arranged in a fixed manner. The angle element 41 is thus situated in a stop position in which a rotational movement about the pivot point 42 is blocked. On movement of the flap 3 from the first position towards the second position, the flap 3 is raised so that the angle element 41 moves away from the fixed stop 46 and consequently no longer lies against it, meaning that the angle element 41 and thus the reinforcement strip 43 can now move towards the flap 3, thereby inevitably enabling a movement of the third side edge 19 towards the opening 1. In other words, the angle element 41 is moved from the stop position into a release position, making a movement of the third side edge 19 towards the opening 1 possible. The movement of the third side edge 19 towards the opening 1 can be supported by a spring element 47 which is attached to the third side edge 19 and the frame element 6 and is under tension in the first position of the flap 3 and therefore pre-stresses the third side edge 19 towards the opening 1. Alternatively, or additionally, the fourth side edge 20 can be pre-stressed towards the flap 3, as illustrated by the spring element 48 in Figure 11. A second embodiment of a blocking element 40 is shown in Figure 12 and is designed as a movement-coupled locking hook 50 connected with the flap 3. In the first position of the flap 3, the locking hook 50 engages with the third side edge 19 and holds the third side edge 19 in a fixed manner such that it cannot move towards the opening 1. The locking hook 50 is pivotably mounted about a pivot point 51, which is designed on the hinge element 24 in the illustrated embodiment, but can also be provided elsewhere. The locking hook 50 is connected via a movement converter 52. The movement converter 52 is designed in the form of a cable whose first end is connected to the longitudinal end of the locking hook 50, which faces away from the third side edge 19, whereas the second end is mounted on the axis 4 of the flap 3. This makes it is possible for the movement converter 52 to convert the movement of the flap 3 from the first position towards the second position into a movement of the locking hook 50 releasing the third side edge 19. The axis 4 rotates due to upward pivoting of the flap 3, causing the cable to wind up on the axis 4, which in turn makes the cable pull at the longitudinal end of the locking hook 50 so that the locking hook 50 rotates around the pivot point 51 and the hook therefore disengages from the third side edge 19. In this embodiment, a spring element 47 is also provided, which supports the movement of the third side edge 19 towards the opening 1 when the flap 3 moves towards the second position.
Alternatively, or in addition to the options described above for locking or fixing the semi-stationary seal 14 in its stretched position, it is also provided in the scope of the invention that the third side edge 19 is connected with the flap 3 via a movement-coupled connection 60 in such a manner that a movement of the flap 3 from the first position towards the second position moves the third side edge 19 towards the opening 1. The movement-coupled connection 60 between the third side edge 19 and the flap 3 has a cable system 61 with a cable 62 and three pulleys 63, 64 and 65, as can be seen in Figure 13. Here, one end of the cable 62 is attached to the axis 4 of the flap 3, whereas the other end of the cable 62 is fixed to the third side edge 19. In between, the cable 62 is guided via the pulleys 63, 64, 65. An upward pivoting movement of the flap 3 towards its second position causes the cable 62 to wind up on the axis 4, which ultimately leads to the cable 62 pulling at the third side edge 19 and moving it towards opening 1 due to its degree of freedom. This movement coupling has the advantage that, for a manual pivoting movement of the flap 3 or a pivoting movement of the flap executed by means of a drive, one is not dependent on the hydrostatic pressure of the fluid in order to ensure the folding of the semi-stationary seal 14. A further option for a movement-coupled connection of semi stationary seal 14 and flap 3 is illustrated in Figure 14. In this embodiment, the first side edge 15 of the semi-stationary seal 14 is similarly attached again to the flap 3, whereas the second side edge 16 is also attached again to the frame element 6. However, in this case, the semi-stationary seal 14 comprises a flexible section 71 which is attached to the frame element 6, and a dimensionally stable section 72, which is attached to flap 3. Both sections 71 and 72 cover, in the first position of the flap 3, a quarter-circular area of the corner region between flap 3 and frame element 6 so that a lateral entry of fluid is prevented by the semi-stationary seal 14. Both sections 71 and 72 can be designed to be approximately the same size. It is also conceivable for the flexible section 71 to span a quarter-circular area in the first position of the flap 3 and to be attached to both the flap 3 and the frame element 6, whereas the sheet-like and dimensionally stable section 72 is attached only to the flap 3 and spans an eighth circular area. The dimensionally stable section 72 is further designed such that, on movement of the flap 3 towards its second position, the flexible section 71 enfolds and collapses on the border 73 of the sheet-like, dimensionally stable section 72. Here, the part of the third side edge 74 extending between the first and second side edge 15, 16 and to be considered part of the dimensionally stable section 72 remains dimensionally stable during the movement of the flap 3 towards the second position, causing the edge or the border 73 to form a type of folding border 73 for the flexible section 71.
In such an embodiment as that shown in Figure 14, both the dimensionally stable and the semi-stable section 71, 72 of the semi-stationary seal 14 form equal parts of the semi-circular area. It is only important that the dimensionally stable section 72 does not interfere in the swinging of the flap 3. For this purpose, the dimensionally stable section 72 is arranged at the side of the frame element 6 in the second position of the flap 3, in which the flap 3 lies against the stationary seal 11. The width of the frame element 6 and the size of the dimensionally stable section 72 must be coordinated so that the dimensionally stable section 72 can be arranged at the side of the frame element 6 in the second position of the flap 3. Alternatively, the semi-stationary seal 14 shown in Figure 14 can also have a fourth side edge so that the semi-stationary seal 14 spans a quadrangular area in the first position of the flap 3.
