Description

The invention relates to a device against the penetration of liquid, comprising at least a first vertical support and a second vertical support, wherein each vertical support has a profile cross-section with a first leg and a perpendicular thereto arranged second leg, a sealing strip per vertical support, respectively extending the first leg in the vertical direction, a shut-off device for abutment against the sealing strips of the first leg to shut off in a mounting position formed between the first and the second vertical support gap, and a locking device for fixing the shut-off device in the mounting position.

Devices of this type can be used, for example, to protect buildings against ingress of liquids by mounting them in front of corresponding building or property openings. In addition, such devices can be linked to dams in order to protect areas threatened by flooding from flooding.

A device of the type mentioned is, for example DE 20 2016 101 593 U1 known. In this, the shut-off device is automatically locked by means of a resilient holding device between the vertical supports in the mounting position. This facilitates the installation of the shut-off device between the vertical struts compared to conventional clamping lever systems. However, since the resilient retaining means are arranged on the front sides of the shut-off device, the length of the shut-off device must be tuned very accurately to the distance between the vertical supports. In practice, however, it has been found that such an automatic latching mechanism is sensitive to mounting differences if the vertical supports are not accurately positioned. If the elements of the shut-off device are too short, they must be rebuilt consuming. On the other hand, if the elements of the shut-off device are too long, it is necessary to shorten them during installation on site.

The invention is primarily based on the object to remedy this situation. In particular, the invention aims to provide a device against the penetration of liquid, which on the one hand quickly build up and dismantle when needed, manages with inconspicuous stationary elements, is insensitive to mounting tolerances and also can be easily and inexpensively finished.

This object is achieved by a device having the features of claim 1. The inventive device is characterized in particular by the fact that the locking device has a shaft with a laterally protruding from the shaft locking hook for engagement with the shut-off device, wherein the shaft is perpendicular to the first leg and is pivotally mounted on a projection of the second leg to the Locking hook with the shut-off device either in or out of engagement.

As a result, the above-explained difficulties are overcome. About the locking hook can be compensated for any tolerances when setting up the vertical supports readily. Nevertheless, the locking device remains simple in construction. It also requires little space, so that the vertical supports can be designed as a particularly slim unobtrusive components.

Advantageous embodiments of the invention are the subject of further claims.

Compared to conventional systems with clamping lever protruding components can be completely avoided because the locking device can be almost completely embedded in the vertical supports and the shut-off device. An entanglement with alluvial flotsam is excluded. In addition, there is no risk of injury to operators or passersby by eliminating protruding components.

Preferably, the shaft has a head for attachment of a rotary tool, whereby the pivoting of the shaft is facilitated.

The locking hook can be arranged and configured such that it presses the shut-off device against the sealing strip in its locking position.

Furthermore, it is possible to design the locking device in such a way that the locking hook in its locking position presses the shut-off device in the direction of the ground. Separate clamping mechanisms in the vertical direction can be omitted in this case.

In a further embodiment, it is provided that the locking hook is supported in its locking position in the direction perpendicular to the first leg against the projection of the second leg. Such support can be made directly on the projection. Preferably, however, the locking hook is in its locking position with the interposition of a guide block against the projection of the second leg supported, which is fixed to the second leg and having a passage opening for guiding the shaft. As a result, a better guidance and alignment of the shaft of the locking device is achieved. The associated projection of the second leg can thereby be kept relatively slim and inconspicuous. In addition, this makes it possible to produce the vertical supports very easily and inexpensively as extruded profiles, which only need to be provided in the region of the projections with an opening for supporting the shaft. The processing effort on the part of the vertical supports remains very low.

In a further embodiment, the locking hook is releasably secured to the shaft, whereby the assembly of the locking device is facilitated on the vertical supports.

Furthermore, it is possible to provide on the locking hook a beveled contact surface for engagement with the shut-off device. Alternatively or additionally, the shut-off device may also have a bevelled contact surface for engagement with the locking hook. This favors the pivoting of the locking hook in the locking position in which the locking hook presses with its contact surface in the direction of the first leg against the shut-off device. About the oblique contact surfaces, the shut-off device is increasingly urged against the sealing strip during pivoting of the locking hook in the locking position.

In a further embodiment, the shut-off device comprises a spring element for engagement with the locking hook. Again, the pivoting of the locking hook is favored in its locking position, since slight initial incorrect positioning of the shut-off device, which could lead to a blocking of the locking hook, can be compensated by the spring element.

In addition, for this purpose, the longitudinal axis of the shaft can be angled perpendicular to the first leg. When pivoting the shaft in the locking position, the free end of the locking hook thus moves in the direction of the first leg and the sealing strip. As a result, tolerances and differences in wall thickness on the part of the shut-off device can be compensated, so that the shut-off device is always urged against the sealing strip.

Furthermore, it is possible to form the projection of the second leg on a tab, which in turn is attached to the second leg. As a result, the profile cross section of the vertical support can be simplified. In the simplest case, the vertical support can be designed with an L or T profile cross section. The tab can for example be welded or screwed or fastened in any other way on the second leg.

In a further embodiment, it is provided that the shaft is rotatably mounted with an end portion on the first leg. This ensures a stable position of the shaft on the vertical support.

Furthermore, a suitable for the above-mentioned device, particularly advantageous locking device is proposed. This includes a shaft and a locking hook for engagement with a shut-off device that projects laterally from the shaft and is releasably secured to the shaft. The shaft has a portion for pivotable mounting about its longitudinal axis and a head for applying a turning tool.

That in the 1 to 3 illustrated first embodiment relates to a device 1 against the penetration of liquid. Such devices can be used, for example, to shut off a building opening against the passage of liquid, in particular water and are therefore particularly suitable for temporary protection against flooding. Furthermore, devices of the invention can also be used to protect against the penetration of other liquids such as oil, fire water and the like. In addition, it is possible to build dams by linking such devices. If necessary, the device can be set up quickly, for example in the case of a threatening flood situation. If the danger is over, the device can be dismantled accordingly quickly.

The device 1 includes a first vertical support 10 and a second vertical support 11 which, for example, sealed on a building wall 2 be attached to the construction of dams but also freely placed and can be anchored to the ground. If necessary, the gap 3 between two adjacent vertical supports 10 and 11 by a shut-off device 20 locked. As a rule, one becomes the vertical supports 10 and 11 attach stationary, the shut-off device 20 but only install as needed.

The shut-off device 20 For example, it may be formed as a dam beam or dam beam stack. It has at least one hollow profile element 21 on, which serves as a dam beam. In the 1 and 2 are several vertically stacked hollow profile elements 21 to recognize, which have the same profile cross-section. However, it can also be used hollow profile elements of different thickness. Thus, it is possible, for example, to use thicker hollow profile elements as dam beams in the base area of a dam and to use thinner dam beams in the region of the dam crown. The shut-off device thus formed 20 If necessary, between the vertical supports 10 and 11 installed and then seals against these and continue against the ground 4 from.

In a modification of the embodiment, the shut-off device 20 also have one or more plates for shutting off the gap, which at the vertical supports 10 and 11 be attached. Instead of solid sheets so-called honeycomb panels are preferably used, which consist of two supporting outer skins and a support core in honeycomb shape, so that a three-layer composite construction is formed in sandwich construction. Furthermore, it is possible dam beams 21 and to combine plates or to stack several plates one above the other.

Preferably, the hollow profile elements 21 the shut-off device 20 Openings for flooding the interior of the same with on the device 1 on standing liquid. The openings are automatically on the front sides 22 the hollow profile elements 21 when the hollow profile elements 21 be cut to length from longer profiles. Otherwise, appropriate openings to the interior 24 on the front sides 22 and / or attached to the liquid-facing side.

The vertical supports 10 and 11 each have an L-shaped profile cross-section. Therefore, the shut-off device 20 from the side, ie perpendicular to the opening cross-section of the space 3 between the vertical supports 10 and 11 be used and does not, as usual with U-profiles, threaded from above. This facilitates the assembly considerably. For smaller elements, a one-man assembly is possible. In addition, the same vertical support profile for dam beams of different thickness can be used.

Every vertical support 10 and 11 has a first leg to form the L-profile 12 and a second leg 13 on. In installation position serve the first leg 12 the support of the at the shut-off device 20 adjacent fluid pressure, thus extending parallel to the opening cross section of the gap 3 and point in the direction of the liquid side of the device 1 while those to the first thighs 12 vertical second leg 13 facing each other and thus point to each other. When installed, the end faces 22 the shut-off device 20 each through a gap 23 from the second thighs 13 spaced, whereby the assembly is facilitated.

The vertical supports 10 and 11 For example, they can be made of an extruded profile, from which the desired length is cut to length according to the required column height, as required.

When linking several devices 1 to a dam can two vertical struts 10 and 11 with the backs of their second thighs 13 be put together, so that overall results in a T-profile. Such a T-profile can also be manufactured as a unit, for example extruded.

To ensure a good sealing effect between the shut-off device 20 and the first thighs 12 the vertical supports 10 and 11 each vertical support is a sealing strip 30 provided, each on the first leg 12 extends in the vertical direction. Preferably, the sealing strips 30 on the first thighs 12 attached. However, it is also possible the sealing strips 30 at the shut-off device 20 , ie in the first embodiment of the hollow profile elements 21 to install.

The sealing strips 30 are in the unloaded state on the shut-off device 20 pointing side of the first leg 12 sublime, so are in the direction of the shut-off device 20 further than surrounding sections, so that the hollow profile elements 21 when installed between the vertical supports 10 and 11 initially in abutment against the sealing strips 30 reach. To squeeze the sealing strips 30 To avoid, can on the first thighs 12 projections 14 be provided, which is a shift of the shut-off device 20 in the direction of the first leg 12 limit. This allows the sealing strips 30 be performed very soft, so that even at very low contact pressures results in a good sealing effect. This is especially at low liquid levels at the shut-off device 20 important. If the liquid level rises at the shut-off device 20 on, increases the contact pressure of the shut-off device 20 in the direction of the first leg 12 , The sealing strips can 30 optionally compressed so far that the hollow profile elements 21 the shut-off device 20 in abutment against the projections 14 passes, which the sealing strips 30 protect against squeezing.

The projections 14 can, as in 3 exemplified in the profile of the vertical supports 10 and 11 be integrated, making it very easy to produce. However, it is also possible the sealing strips 30 and the projections 14 to form a unit, which at the first thighs 12 is attached. In this case it is also possible to use the projections 14 made of a sealing material, for example, also in molding, which has a greater hardness than the sealing strips 30 and is sufficiently hard to protect the soft sealing strips 30 to care. In the unloaded state are the sealing strips 30 in any case, continue towards the shut-off device 20 before than the projections 14 ,

Furthermore, the device 1 a locking device 40 for setting the shut-off device 20 in their mounting position, which in 3 is shown in more detail. This locking device 40 can be completely in the gap 23 between the second leg 13 and the front side 22 the shut-off device 20 be housed.

The locking device 40 has a wave 41 with one side of the shaft 41 protruding locking hook 42 on. The locking hook 42 can by pivoting the shaft 41 around its longitudinal axis A in engagement with the shut-off device 20 be brought to fix them in their mounting position and against the sealing strip 30 keep pressed.

The wave 41 runs perpendicular to the first leg 11 the associated vertical support 10 respectively. 11 , She is at a head start 15 of the second leg 12 around its longitudinal axis A pivotally mounted and has a correspondingly formed section. For swivel mounting of the shaft 41 is at the lead 15 a corresponding opening 16 educated. This is usually in coordination with the respective installation situation in the lead 15 of the second leg 12 drilled.

By pivoting the shaft 41 can the locking hook 42 with the shut-off device 20 optionally in or disengaged.

To improve the guidance of the shaft 41 can on the second leg 12 a leader block 50 be arranged, which has a passage opening 51 through which the shaft 41 passed through. Preferably, the guide block 50 at the back of the projection 15 of the second leg 12 arranged so that it does not appear to the outside, in particular not of the associated vertical support 10 respectively. 11 protrudes outwards.

Alternatively or in addition to the guide block 50 can the wave 41 with an end portion in one on the first leg 12 trained opening or in one on the first leg 12 mounted bearings are rotatably mounted.

Preferably, the shaft has 41 a head 43 for applying a turning tool. When installing the locking device 40 on a vertical support 10 respectively. 11 becomes the wave 41 from the outside through the opening 16 of the projection 15 and optionally further through the passage opening 51 of the guide block 50 introduced. At the head 43 opposite end portion of the shaft 41 then the locking hook 42 attached. This can, for example, to the shaft 41 be welded. Preferably, the locking hook 42 however, releasable on the shaft 41 attached. In particular, it is possible the shaft 41 with the locking hook 42 to screw or else in a non-rotatable manner to couple.

For example, the locking hook 42 on a threaded portion of the shaft 41 slid or screwed on and countered between two also screwed onto the threaded portion nuts. This solution has the advantage that the position of the locking hook 42 on the wave 41 can be adjusted. This makes it possible to compensate for dimensional tolerances and / or a wall thickness adjustment to the shut-off device 20 make.

The locking hook 42 is configured and arranged so that this from a first retracted position in which the shut-off device 20 between the vertical supports 10 and 11 is insertable, about 60 to 120 °, preferably 80 to 100 ° can be pivoted into a locking position in which the locking hook 42 in engagement with the shut-off device 20 located.

In the locking position, the locking hook holds 42 the shut-off device 20 against the sealing strip 30 of the first thigh 12 pressed.

In addition, the locking device 40 optionally be designed such that the locking hook 42 the shut-off device 20 at the same time also in the direction of the underground 4 suppressed.

As 3 shows is the locking hook 42 in its locking position with the interposition of the guide block 50 against the lead 15 of the second leg 13 supported. However, it is also possible in principle, the locking hook 42 immediately against the lead 15 of the second leg 13 in a direction perpendicular to the first leg 12 support.

To facilitate the pivoting of the locking hook 42 in the locking position of the locking hook 42 at its contact surface 44 for engagement with the shut-off device 20 beveled. Equally, alternatively or additionally, the shut-off device 20 a beveled contact surface 25 for engagement with the locking hook 42 exhibit. Furthermore, it is possible at the shut-off device 20 a spring element 60 for engagement with the locking hook 42 provide for pivoting the locking hook 42 to facilitate the locking position. The spring element 60 This is done by the locking hook 42 something compressed.

4 shows a second embodiment with modified vertical support 10 respectively. 11 and modified bearing of the shaft 41 , Incidentally, the second embodiment corresponds to the first embodiment.

The vertical support 10 of the second embodiment has a simple L-shaped profile cross-section, in which the first and second leg 12 and 13 are formed as flat, connected via corner plates. The projections 14 and 15 of the first embodiment are attached to these plates specially.

Instead of an L-profile, a T-profile can also be used for linked barriers, on which the locking device 40 is provided in duplicate.

The lead 14 may for example be designed as a bar or pad, which on the first leg 12 can be attached.

Similarly, the second projection 15 with the opening 16 for storage of the shaft 41 on a tab 17 formed, in turn, on the second leg 13 attached, for example, can be screwed or welded.

The tab 17 may be U-shaped with two opposite cheeks 19 be executed, each having an opening 16 for storage of the shaft 41 exhibit, as in 5 is indicated below. About the cheeks 19 connecting footbridge 19a can the tab 17 on the second leg 13 be attached. This allows stable storage of the shaft 41 especially even if the free end portion 45 is not stored separately.

The attachment of the tab 17 may optionally so on the shut-off device 20 be tuned that one of her cheeks 19 at the same time an axial abutment for the locking hook 42 forms.

Furthermore, in the second embodiment, the shaft extends 41 up to the first leg 12 , It is also equipped with an end section 45 rotatably mounted on this. For this purpose, on the first leg 12 as a warehouse 18 be provided a blind hole. Alternatively, for storage of the end section 45 the wave 41 an apertured block on the vertical support 10 be attached.

5 shows in the context of a third embodiment, the possibility of the longitudinal axis A the wave 41 to the vertical S on the first thigh 12 support one of the vertical 10 respectively. 11 at an angle α to angle. The locking hook 42 thus pivots in a plane that is the main extension plane of the shut-off device 20 is tilted. 5 shows the locking lever 42 each in the swung-out position. Will the shaft be about the longitudinal axis A turned, the locking lever pivots 42 in its locking position and gets it sooner or later into engagement with the shut-off device 20 , By the angling of the longitudinal axis A the wave 41 can thus compensate for positional tolerances and different wall thicknesses on the shut-off device 20 be achieved. This can ensure that after the pivoting of the locking lever 42 in its locking position, the shut-off device 20 is pressed against the sealing strip.

In the upper section of the illustration of 5 is the wave 41 at a projection 15 of the second leg 13 and continue with its end section 45 on the first leg 12 rotatably mounted. The operation of the shaft 41 via their head 43 for example, with the help of a suitable key. The lead 15 in the form of a tab 17 is on the second leg 13 the vertical support attached, but may also be integrally formed therewith. In the latter case, an oblique bore in the vertical support 10 respectively. 11 set over which the opening 16 at the lead 15 and an associated blind hole on the first leg 12 as a warehouse 18 be created.

In the lower section of the illustration of 5 is another variant of the locking device 40 with angled shaft 41 shown. The wave 41 is here on a tab 17 with two cheeks 19 rotatably mounted. A storage on the first leg 12 This is not necessary. The tab is 17 is with one cheek 19 connecting footbridge 19a on the second leg 13 attached. About oblong holes 19b can the angle of attack α the wave 41 adjusted as needed. In addition, this can be a positioning of the locking device 40 perpendicular to the first leg 12 and the shut-off device 20 respectively. The locking hook 42 can on the free end section 45 the wave 41 screwed on and optionally provided with a backup. He is positioned so that he is at the first leg 12 pointing cheek 19a can support axially. This solution has the advantage that all components can already be prepared ready for installation on the shop floor. Due to the customization possibilities, similar locking devices can be used 40 with uniform tabs 17 for different types of vertical supports 10 respectively. 11 and shut-off devices 20 be used.

The invention has been explained in more detail above with reference to exemplary embodiments and further modifications. In particular, individual technical features, which have been explained above in the context of further individual features, can 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. In particular, the modifications explained in the context of the second and third exemplary embodiments can also be transmitted individually to the respective other exemplary embodiments. The invention is therefore expressly not limited to the described embodiments and the described modifications, but includes all embodiments defined by the claims.
