    专利说明:

    The invention relates to a device against the penetration of liquid, comprising at least a first vertical support and a second vertical support, each vertical support having a profile cross-section with a first leg and a second leg perpendicular thereto, a sealing strip per vertical support, extending in each case on 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 the entry of liquids by these are mounted in front of appropriate 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 known for example from DE 2020 16 101 593 U1. 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 comprises a shaft with a laterally protruding from the shaft locking hook for engagement with the shut-off device, wherein the shaft perpendicular to the first leg between the second leg and the shut-off device and extends to a projection of the second Leg is pivotally mounted to bring the locking hook with the shut-off device either in or out of engagement. In addition, locking hook presses in its locking position, the shut-off device against the sealing strip and / or towards the ground.
    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, since 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 attaching 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 such that the locking hook presses the shut-off device in the direction of the ground in its locking position. 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 supported in its locking position with the interposition of a guide block against the projection of the second leg, which is secured 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 of 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-described 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 rotary tool.
    The invention will be explained in more detail with reference to embodiments shown in the drawing. The drawing shows in:
    1 is a front view of a first embodiment of a device against the ingress of liquid,
    FIG. 2 shows a vertical section through the device according to FIG. 1, FIG.
    3 is a horizontal section through the locking device of the device according to Fig. 1,
    Fig. 4 is a vertical section through a second embodiment of a device against the penetration of liquid, and in
    Fig. 5 is a vertical section through a third embodiment of a device against the penetration of liquid.
    The illustrated in FIGS. 1 to 3 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, inventive devices 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 comprises a first vertical support 10 and a second vertical support 11 which are sealed, for example, attached to a building wall 2, in the construction of dams, however, also freely placed and can be anchored in the ground. If necessary, the intermediate space 3 between two adjacent vertical supports 10 and 11 is closed by a shut-off device 20. In general, you will attach the vertical supports 10 and 11 stationary, the shut-off device 20, however, attach only as needed.
    The shut-off device 20 may be formed for example as a dam beam or Dammbalkenstapel. It has for this purpose at least one hollow profile element 21 which serves as a dam bar. In FIGS. 1 and 2, a plurality of vertically stacked hollow profile elements 21 can be seen, 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 thus formed shut-off device 20 is installed if necessary between the vertical supports 10 and 11 and then seals against them and continue against the substrate 4 from.
    In a modification of the embodiment, the shut-off device 20 may also include one or more plates for shutting off the gap, which are fastened to the vertical supports 10 and 11. 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 to combine dam bars 21 and plates together or to stack several plates one above the other.
    Preferably, the hollow profile elements 21 of the shut-off device 20 openings for flooding the interior of the same with on the device 1 pending liquid. The openings arise automatically on the end faces 22 of the hollow profile elements 21 when the hollow profile elements 21 are cut to length from longer profiles. Otherwise, corresponding openings may be made to the interior 24 at the end faces 22 and / or at the side facing the liquid.
    The vertical supports 10 and 11 each have an L-shaped profile cross-section. Therefore, the shut-off device 20 can be operated from the side, i. perpendicular to the opening cross section of the gap 3 between the vertical supports 10 and 11 are used and does not need to be threaded from above, as is usual with U-profiles. 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.
    Each vertical support 10 and 11 has a first leg 12 and a second leg 13 to form the L-profile. In the installed position, the first legs 12 serve to support the fluid pressure applied to the shut-off device 20, thus extending parallel to the opening cross-section of the intermediate space 3 and pointing in the direction of the liquid side of the device 1, while the second leg 13 perpendicular to the first legs 12 are opposite one another and with each other. In the installed state, the end faces 22 of the shut-off device 20 are each spaced by a gap 23 of the second legs 13, whereby the assembly is facilitated.
    The vertical supports 10 and 11 can be made for example of an extruded profile, from which the desired length is cut to length according to the required column height as needed.
    When linking several devices 1 to a dam two vertical struts 10 and 11 can be put together with the backs of their second leg 13, so that the overall result is 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 legs 12 of the vertical supports 10 and 11, a sealing strip 30 is provided per vertical support, which extends in each case on the first leg 12 in the vertical direction. Preferably, the sealing strips 30 are attached to the first legs 12. However, it is also possible that the sealing strips 30 on the shut-off device 20, i. to be attached to the hollow profile elements 21 in the first embodiment.
    The sealing strips 30 are raised in the unloaded state on the side facing the shut-off device 20 side of the first leg 12, so are in the direction of the shut-off 20 further than surrounding sections, so that the hollow profile elements 21 in their installation between the vertical supports 10 and 11 first get in abutment against the sealing strips 30. In order to avoid a squeezing of the sealing strips 30, projections 14 may be provided on the first legs 12, which limit a displacement of the blocking device 20 in the direction of the first leg 12. As a result, the sealing strips 30 can be made very soft, resulting in a good sealing effect even at very low contact pressures. This is important especially at low liquid levels at the shut-off device 20. If the liquid level at the shut-off device 20 increases, the contact pressure of the shut-off device 20 increases in the direction of the first leg 12. The sealing strips 30 can optionally be compressed to the extent that the hollow profile elements 21 of the shut-off device 20 comes into abutment against the projections 14, which Protect sealing strips 30 against squeezing.
    The projections 14 may, as shown by way of example in FIG. 3, be integrated in the profile of the vertical supports 10 and 11, whereby they can be produced very easily. However, it is also possible to combine the sealing strips 30 and the projections 14 into a unit, which is attached to the first legs 12. In this case, it is also possible to manufacture the projections 14 from a sealing material, for example also in strip form, which has a greater hardness than the sealing strips 30 and is sufficiently hard to provide protection of the soft sealing strips 30. In the unloaded state, the sealing strips 30 are in any case in the direction of the shut-off device 20 before the projections 14th
    Furthermore, the device 1 has a locking device 40 for fixing the shut-off device 20 in its mounting position, which is shown in more detail in Fig. 3. This locking device 40 can be completely accommodated in the gap 23 between the second leg 13 and the end face 22 of the shut-off device 20.
    The locking device 40 has a shaft 41 with a laterally protruding from the shaft 41 locking hook 42. The locking hook 42 can be brought by pivoting the shaft 41 about its longitudinal axis A into engagement with the shut-off device 20 to fix them in their mounting position and to keep pressed against the sealing strip 30.
    The shaft 41 is perpendicular to the first leg 11 of the associated vertical support 10 and 11. It is pivotally mounted on a projection 15 of the second leg 12 about its longitudinal axis A and has a correspondingly formed portion on. For pivotable mounting of the shaft 41, a corresponding opening 16 is formed on the projection 15. This is usually bored in coordination with the respective installation situation in the projection 15 of the second leg 12.
    By pivoting the shaft 41, the locking hook 42 can be brought with the shut-off device 20 either in or out of engagement.
    To improve the guidance of the shaft 41 may be arranged on the second leg 12, a guide block 50 which has a passage opening 51 through which the shaft 41 is passed. Preferably, the guide block 50 is arranged on the rear side of the projection 15 of the second leg 12 so that it does not appear outwardly, in particular does not protrude outwards from the associated vertical support 10 or 11.
    Alternatively or in addition to the guide block 50, the shaft 41 can be rotatably mounted with an end portion in an opening formed on the first leg 12 or in a bearing fixed to the first leg 12.
    Preferably, the shaft 41 has a head 43 for applying a rotary tool. When mounting the locking device 40 on a vertical supports 10 and 11, the shaft 41 is inserted from the outside through the opening 16 of the projection 15 and optionally further through the passage opening 51 of the guide block 50. On the head 43 opposite end portion of the shaft 41, the locking hook 42 is then attached. This can be welded, for example, to the shaft 41. Preferably, however, the locking hook 42 is releasably secured to the shaft 41. In particular, it is possible to screw the shaft 41 to the locking hook 42 or to couple it in a non-rotatable manner in any other way.
    For example, the locking hook 42 can be pushed or screwed onto a threaded portion of the shaft 41 and countered between two also screwed onto the threaded portion nuts. This solution has the advantage that the position of the locking hook 42 can be adjusted on the shaft 41. This makes it possible to compensate for dimensional tolerances and / or make a wall thickness adjustment to the shut-off device 20.
    The locking hook 42 is configured and arranged such that it pivots from about 60 to 120 °, preferably 80 to 100 ° in a locking position from a first retracted position in which the shut-off device 20 between the vertical supports 10 and 11 can be inserted can be, in which the locking hook 42 is in engagement with the shut-off device 20.
    In the locked position, the locking hook 42 holds the shut-off device 20 pressed against the sealing strip 30 of the first leg 12.
    In addition, the locking device 40 may optionally be designed such that the locking hook 42 pushes the shut-off device 20 at the same time in the direction of the ground 4.
    As shown in FIG. 3, the locking hook 42 is supported in its locking position with the interposition of the guide block 50 against the projection 15 of the second leg 13. However, it is also possible in principle to support the locking hook 42 directly against the projection 15 of the second leg 13 in a direction perpendicular to the first leg 12.
    To facilitate the pivoting of the locking hook 42 in the locking position of the locking hook 42 may be bevelled at its contact surface 44 for engagement with the shut-off device 20. Equally, as an alternative or in addition, the shut-off device 20 may have a bevelled contact surface 25 for engagement with the locking hook 42. Further, it is possible to provide on the shut-off device 20, a spring element 60 for engagement with the locking hook 42 to facilitate the pivoting of the locking hook 42 in the locking position. The spring element 60 is hereby slightly compressed by the locking hook 42.
    Fig. 4 shows a second embodiment with modified vertical support 10 and 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 legs 12 and 13 are formed as flat, corner-connected plates. The projections 14 and 15 of the first embodiment are attached to these plates.
    Instead of an L-profile, a T-profile can be used in chained barriers, on which the locking device 40 is provided in duplicate.
    The projection 14 may for example be designed as a bar or pad, which may be attached to the first leg 12.
    Similarly, the second projection 15 is formed with the opening 16 for supporting the shaft 41 on a tab 17, which in turn can be attached to the second leg 13, for example screwed or welded. The tab 17 may optionally be U-shaped with two opposite cheeks 19, each having an opening 16 for supporting the shaft 41, as indicated in Fig. 5 below. Via a cheek 19 connecting web 19 a, the tab 17 can be attached to the second leg 13. This allows stable storage of the shaft 41 in particular even if the free end portion 45 is not stored separately.
    The attachment of the tab 17 may optionally be tuned to the shut-off device 20, that one of its cheeks 19 simultaneously forms an axial abutment for the locking hook 42.
    Furthermore, in the second embodiment, the shaft 41 extends to the first leg 12. It is also rotatably mounted with an end portion 45 at this. For this purpose, a blind hole may be provided on the first leg 12 as a bearing 18. Alternatively, for supporting the end portion 45 of the shaft 41, a block provided with an opening may be attached to the vertical support 10.
    Fig. 5 shows, in the context of a third embodiment, the possibility of the longitudinal axis A of the shaft 41 to the vertical S on the first leg 12 of the vertical supports 10 and 11 an angle α. The locking hook 42 thus pivots in a plane which is tilted to the main extension plane of the shut-off device 20. Fig. 5 shows the locking lever 42 respectively in the pivoted position. If the shaft is rotated about the longitudinal axis A, the locking lever 42 pivots into its locking position and sooner or later comes into engagement with the shut-off device 20. By angling the longitudinal axis A of the shaft 41 can thus compensate for positional tolerances and different wall thicknesses of the shut-off device 20 can 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 portion of the illustration of Fig. 5, the shaft 41 is rotatably mounted on a projection 15 of the second leg 13 and further with its end portion 45 on the first leg 12. The operation of the shaft 41 via the head 43, for example by means of a suitable key. The projection 15 in the form of a tab 17 is attached to the second leg 13 of the vertical support, but may also be formed integrally therewith. In the latter case, an oblique bore in the vertical support 10 and 11 is set, via which the opening 16 on the projection 15 and an associated blind hole on the first leg 12 are provided as a bearing 18.
    In the lower portion of the illustration of Fig. 5, a further variant of the locking device 40 is shown with angled shaft 41. The shaft 41 is in this case rotatably mounted on a tab 17 with two cheeks 19. A storage on the first leg 12 is not absolutely necessary in this case. The tab 17 is attached to the cheeks 19 connecting web 19 a on the second leg 13. Via slots 19b, the angle of attack ot the shaft 41 can be adjusted as needed. In addition, this can be done by positioning the locking device 40 perpendicular to the first leg 12 and the shut-off device 20. The Verrieglungshaken 42 can be screwed onto the free end portion 45 of the shaft 41 and optionally provided with a fuse. He is positioned so that it can be supported axially on the side facing the first leg 12 cheek 19a. This solution has the advantage that all components can already be prepared ready for installation on the shop floor. Due to the possibilities of adaptation, similar locking devices 40 with uniform tabs 17 can be used for different types of vertical supports 10 and 11 and shut-off devices 20.
    The invention has been explained above with reference to 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.
