Description

The invention relates to a drivable automatically closing vertical bulkhead to protect against the penetration of liquid.

To protect passages and building openings against the ingress of surface water and other liquids, so-called folding bulkheads are known, in which a flap is automatically erected by a swimmer by pivoting about an axis of rotation. In an open position, however, the flap is flush with the floor so that a vehicle can drive over it. An example of such a folding partition is known from DE 10 2015 115 023 A1.

If a high storage height is required, there is a large bridge width for the flap in the lying position. In order to allow heavy vehicles to drive over the flap, it must be designed and supported accordingly. This results in a heavy-weight construction, which requires a lot of material. Although the associated base pan of the flap can be made relatively flat, it has a large width with a corresponding storage height. In the state of flooding, the open trough is covered by liquid and may therefore not be visible, so warning devices are necessary to warn of a possible risk of falling.

A drive-over automatically closing vertical bulkhead according to the preamble of claim 1 is known from DE 102 43 498 A1. The bulkhead element of the same is arranged in a trough and has a lower density than water. For this purpose, a float can be attached to the bulkhead element. When the tub is flooded, the bulkhead element floats due to the buoyancy caused thereby and thereby automatically reaches the position lifted out of the ground. In the lowered state, the bulkhead element is covered with a pivotable flap.

From GB 2 465 178 A1 vertical bulkhead that can be driven over is known, the extension of which is supported in the vertical direction by gas pressure springs. However, manual operation is required to extend.

DE 44 37 098 A1 is a vertical bulkhead, which, however, requires a drive device in order to electrically extend the associated bulkhead element.

Finally, a vertical bulkhead is described in US 2002/083651 A1, in which a piston-cylinder arrangement is used to extend the bulkhead element.

The present invention has for its object to provide a drivable automatically closing device to protect against the penetration of liquid, which can be produced with less effort, requires little space in the floor and has a high level of operational reliability.

This object is achieved by a drivable automatically closing vertical bulkhead with the features of claim 1. The vertical bulkhead according to the invention comprises at least one bulkhead element and vertical guide devices therefor, the at least one bulkhead element being movable between a recessed position in the floor and a position lifted out of the floor by displacement in the vertical direction, at least one spring device which engages the at least one bulkhead element and in the recessed position is biased against the floor, a locking mechanism that secures the at least one bulkhead element in the recessed position, and a float that mechanically unlocks the locking mechanism when a predetermined liquid level is reached in order to shift the at least one bulkhead element into the raised position to cause the spring device.

The solution according to the invention is compared to a folding bulkhead with a significantly reduced bridge width, so that this can be used above all where a passage of the opening to be shut off by heavy vehicles such as trucks,

Construction machinery and the like is required and / or there is insufficient space for a flap in front of an opening.

This results in an overall lower total weight and a reduced material expenditure.

In addition, the formation of an open pit is avoided in front of the vertical bulkhead when it is in the raised position, which increases safety.

Since the float only serves to unlock the locking mechanism and is not required to provide the force for lifting the at least one bulkhead element, it can be made relatively small. This reduces the installation space required in the floor to accommodate the vertical bulkhead.

The vertical bulkhead is closed automatically by the spring device being triggered by rising liquid, i.e. without electrical actuation or actuation by one person. Advantageous embodiments of the invention are the subject of further claims.

Preferably, the at least one bulkhead element and the float are arranged in a tub which has an inlet for surface water. The trough can either be preassembled as a corresponding container together with the other components of the vertical bulkhead and installed in the floor. Alternatively, a corresponding trough can also be provided on site, in which the vertical bulkhead is mounted.

The width of the tub is preferably smaller than the height of the at least one bulkhead element in its fully raised position above the floor, which results in a reduced space requirement compared to conventional folding bulkheads.

In a further embodiment, two bulkhead elements are provided, which are arranged such that they come to lie parallel with one another in the lowered position with their main extension planes and are stacked on top of one another at their edges in the lifted position, so that the main extension planes are then in a common one Level collapse. This makes it possible to reduce the depth of the trough and / or to provide a particularly large storage height.

For this purpose, a first, upper bulkhead element can be guided in a link and have a driver which, after being lifted out, engages with a second, lower bulkhead element in order to take it along. In this case, the spring device preferably engages the first, upper bulkhead element. The second, lower bulkhead element is thus pulled into its raised position by the first, upper bulkhead element.

[0019] In a further advantageous embodiment, the spring device comprises at least one gas pressure spring. As a result, the lifting of the at least one bulkhead element after unlocking the locking mechanism can be provided with a damping device in order to prevent the bulkhead element from being extended too suddenly. Alternatively, it is possible to combine a conventional spring, for example a coil spring, with a damper.

Basically, it is possible to sink the bulkhead element in the ground so that its upper edge in the lowered position ends with the surrounding road. In this case, however, the corresponding axle loads must be supported via the bulkhead element. To avoid this, according to a further advantageous embodiment of the invention, the at least one bulkhead element in the lowered position can be bridged by a bridge plate which can be driven over and which is supported against the ground when the bulkhead element is lowered and which can be lifted out by the at least one bulkhead element. The bulkhead element is thus decoupled from said axle loads in its lowered position. When the locking mechanism is triggered, the bulkhead element simply takes the mobile bridge plate with it.

Furthermore, a floor frame can be provided, in which an inlet for liquid and the bridge plate are embedded. This makes it stable with little effort

Patent Office drive-over structure created, which protects the bulkhead element in the lowered position. According to a further advantageous embodiment of the invention, the at least one bulkhead element along its lower edge has a laterally projecting bar, which comes into contact with a stationary horizontal base bar in the raised position of the at least one bulkhead element, the at least one between the projecting bar a bulkhead element and the bottom bar at least one elastic sealing bar is arranged, which is attached to the projecting bar or on the bottom bar. In this way, on the one hand, a stop in the vertical direction can be provided. On the other hand, undermining of the bulkhead element by liquid is reliably prevented, since a defined system is provided via the bottom bar and no unevenness in the floor has to be compensated for via the sealing bar.

Furthermore, an L or UProfile element can be provided as a vertical guide device above the bottom of each end of the bulkhead element, the at least one bulkhead element being pressed against a leg of such a profile element in its raised position by water pressure. A sealing strip is preferably fastened to this leg and / or the corresponding contact surface of the at least one bulkhead element. By concatenating several scrap elements at their ends and corresponding profile elements, automatically closing barriers can be created, which are closed without the aid of electrical current and without manual actuation solely by the flowing fluid and the spring force of the spring device. This results in a high level of operational safety, which is in particular independent of a power supply and independent of monitoring by people.

The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. The drawing shows in:

Figure 1 is a cross-sectional view of a first embodiment of a vertical bulkhead according to the invention in the lowered position (open position), [0026] Figure 2 is a cross-sectional view of the vertical bulkhead according to the first embodiment in the raised position (closed position), [0027] Figure 3 is a front view of the first embodiment in the open position including a section through the floor area, the locking mechanism and float being omitted here for the sake of simplicity of illustration, [0028] FIG. 4 is a cross-sectional view of a second exemplary embodiment of a vertical bulkhead according to the invention in the lowered position (open position), and in [0029] FIG. 5 a cross-sectional view of the second embodiment in the raised position (closed position).

The first embodiment shows a drivable automatically closing vertical bulkhead 10, which is shown here by way of example in an installation situation in front of a passage 1, which must be protected against the ingress of surface water if necessary, but should otherwise remain open so that, for example, motor vehicles through drive through passage 1 and people can walk through it.

For the vertical bulkhead 10, a trough 3 is provided in the floor 2 before the passage 1.

The vertical bulkhead 10 of the first embodiment comprises a bulkhead element 11, which is designed as a vertically displaceable plate. This can be made, for example, from one or more profile elements, in particular hollow profile elements, from an aluminum alloy or the like. The bulkhead element 11 can be completely accommodated in the tub 3, as shown in FIG. 1.

Furthermore, the vertical bulkhead 10 has vertical guide devices 12 for the bulkhead element 11, which can be designed, for example, as U or L profile elements 13.

In the exemplary embodiment shown, these vertical guide devices 12 are fastened to a wall 4 on both sides next to passage 1. However, it is also possible to set up corresponding profile elements 13 free-standing, for example for a linked barrier. The vertical guide devices 12 preferably extend into the trough 3 in order to provide sufficient guidance for the bulkhead element 11 in the vertical direction. The latter can be moved between a recessed position in the floor 2 (see FIG. 1) and a position lifted out of the floor 2 (see FIG. 2) by displacement in the vertical direction. The vertical bulkhead 10 is shifted essentially translationally.

On the vertical guide devices 12 sealing strips 14 are attached, against which the bulkhead element 11 is pressed when liquid is present. As an alternative or in addition, corresponding sealing strips 14 can also be attached to the bulkhead element 11. In the raised position of the bulkhead element 11, the sealing strips 14 are pressed against legs of the profile elements 13 opposite the bulkhead element 11 as a result of liquid pressure present at the bulkhead element 11.

The vertical bulkhead 10 further comprises at least one spring device 15 which engages the one bulkhead element 11. In the lowered position of the bulkhead element 11, the spring devices 15 are pretensioned against the base 2 in order to push the sunken bulkhead element 11 up out of the trough 3 into the closed position.

The spring devices 15 can be designed, for example, as gas pressure springs, which act on opposite ends of the bulkhead element 11, as can be seen in FIG. 3. They are preferably supported on the bottom of the tub 3. The gas pressure springs are preferably set such that they can move the bulkhead element 11 quickly from the lowered position into the raised position according to FIG. 2. For security reasons, however, this is done with a certain amount of damping. Instead of two gas pressure springs, other types of springs can also be used. If necessary, an additional damper can be connected in parallel to brake the bulkhead element 11 from being lifted out too suddenly.

The lifting of the bulkhead element 11 is inhibited by a locking mechanism 16 which secures the bulkhead element 11 in the lowered position. For this purpose, the locking mechanism 16 either acts directly on the bulkhead element 11, as is indicated in FIG. 1 with a latching device on the bulkhead element 11, or else on the spring devices 15.

A locking float 17 is assigned to the locking mechanism 16. Both are arranged in the tub 3, which has an inlet 18 for surface water and other liquids. The float 17 interacts mechanically with the locking mechanism 16 in such a way that it mechanically unlocks it when a predetermined liquid level in the tub 3 is reached. After unlocking the locking mechanism 16, the spring devices 15 automatically lift the bulkhead element 11 out of the trough 3 into its raised position for blocking the passage 1. The force required for lifting the bulkhead element 11 is thus provided solely by the spring device 15. The buoyancy force of the float 17 only serves to unlock the locking mechanism 16 and not to raise the partition element 11.

This has the advantage that the float 17 can be made relatively small, since it only has to provide a force for unlocking the locking mechanism 16. As a result, the tub 3 can be built with a relatively small volume. The placement of the float 17 can be chosen relatively freely due to its small dimensions. In particular, this can be arranged laterally next to the bulkhead element 11 in the tub 3. The position of the float 17 in the tub 3 makes it possible to set the triggering threshold of the vertical bulkhead.

On the other hand, it is ensured that when the locking mechanism 16 is unlocked, the bulkhead element 11 automatically moves into a fully raised position

Patent office is proceeding. Intermediate positions, as can occur in systems in which the buoyancy of a float is used to lift the bulkhead element, are avoided in this way. Rather, there are now two clearly defined states, namely a closed position with a bulkhead element 11 raised to its target position and an open position in which the bulkhead element 11 is completely sunk into the ground. As long as no critical level for triggering the locking mechanism 16 is reached in the trough 3, the bulkhead element 11 remains in the open position, i.e. passage 1 remains passable. If the float 17 is raised by the liquid level in the tub 3, the locking mechanism 16 unlocks and releases the bulkhead element 11, which then automatically extends into the raised position and blocks the passage 1 against the ingress of liquid. To open the passage 1, the bulkhead element 11 is manually pressed down by a person until the locking mechanism 16 automatically locks, as a result of which the bulkhead element 11 remains in the open position.

In the illustrated first exemplary embodiment, the bulkhead element 11 is bridged in the lowered position by a bridge plate 19 which can be driven over and which is supported against the floor 2 when the bulkhead element 11 is lowered, so that the bulkhead element 11 is not subjected to any forces when the bridge plate 19 is passed over. The bridge plate 19 is arranged in such a way that when the bulkhead element 11 is lifted out of the trough 3, it is also lifted by it. For this purpose, the bridge plate 19 is preferably embedded in a frame 20, which can optionally also provide the inlet 18 in the form of a grate or the like. In the open position of the vertical bulkhead 10, the surface of the bridge plate 19 and the grate 18 are flush with a roadway or passage surface 2a.

Furthermore, it is possible to support the locking mechanism 16 and the float 17 by means of a holder 21 on the frame 20.

The frame 20 extends along an upper edge of the tub 3, which can be prepared by the customer. However, it is also possible to provide a trough 3 in the form of a container on which the frame 20 has already been formed or mounted. This enables a complete pre-assembly of the vertical bulkhead 10 as a structural unit, which only has to be embedded in a prepared pit at the installation site.

The width of the tub 3 is preferably smaller than the height of the bulkhead element 11 in its raised position above the roadway or passage surface 2a of the floor 2. The vertical bulkhead 10 according to the invention is therefore characterized by a small threshold width in the direction of travel. It can therefore be carried out with a relatively low overall weight.

Furthermore, the bulkhead element 11 may have a laterally projecting strip 22 along its lower edge, which comes into contact with a stationary horizontal base strip 23, for example on the frame 20, in the raised position. This provides a stop in the vertical direction, which defines the raised position of the bulkhead element 11.

Furthermore, at least one elastic sealing strip 24 can be arranged between the projecting ledge 22 of the bulkhead element 11 and the bottom ledge 23, which offers protection against liquid penetration of the bulkhead element 11. Such an elastic sealing strip 24 can be attached to the projecting strip 22 of the bulkhead element 11 and / or to the base strip 23. In addition, such a sealing strip 24 acts as stop damping.

Figures 4 and 5 show a second embodiment, in which the bulkhead element 11 of the first embodiment is replaced by two scrap elements 11a and 11b, which are stacked at their edges in the raised position, so that their main extension levels in a common plane coincide. In the lowered position, the two bulkhead elements 11a and 11b lie with their main extension

Patent office levels in parallel next to each other. With such nesting, a high accumulation height can also be achieved if there is no depth corresponding to the accumulation height available in the ground.

The second exemplary embodiment corresponds to the first exemplary embodiment. The spring device 15 preferably engages the upper bulkhead element 11a. This upper bulkhead element 11a has catches 25 which come into engagement with the second, lower bulkhead element 11b during the lifting of the upper bulkhead element 11a out of the trough 3, in order then to lift this out. The first, upper bulkhead element 11a is guided in a link 26 in order to ensure that the second, lower bulkhead element 11b is carried along and that both bulkhead elements 11a and 11b are stacked one on top of the other.

The invention was explained in more detail above using an exemplary embodiment and further modifications. However, it is not limited to this, but encompasses all the configurations defined by the claims.
