[0002] Device for protection against flooding

[0003] The invention relates to a device for protection against flooding with at least one upright designed to be anchored in a ground sleeve and with at least one wall element that can be attached to the upright.

[0004] With the increasing frequency of extreme weather events, the importance of mobile flood protection systems is growing significantly. The requirements for such systems generally include the ability to set up the systems quickly and easily, a long service life, minimal leakage, and low cost.

[0005] There are various approaches to the basic design that meet the above requirements to varying degrees. For example, sandbags are simple and flexible, but their setup is complex, time-consuming, and labor-intensive. Furthermore, they are prone to leakage. Automatic systems, on the other hand, which feature extendable barriers, are very quick to deploy and have minimal leakage, but they are also extremely expensive and require a great deal of maintenance.

[0006] A widely used type of flood protection system is the so-called insulated beam system. In this system, posts are inserted into prepared ground sleeves. Wall elements are then attached to the posts and any wall connection elements. These wall elements rest on the ground and connect to each other at the posts. With a sound subsoil, leakage is minimal. Disadvantages of the well-known insulated beam systems include their relatively complex construction and considerable cost. Anchoring the posts to the ground, in particular, is complicated and prone to errors.

[0007] The present invention relates to such insulation beam systems, the object of which is to avoid the above disadvantages and to provide a simple and highly effective system.

[0008] According to the invention, these problems are solved by providing a locking element on the upright which, in the assembled state, engages in a recess of the ground sleeve and fixes the upright in this position.

[0009] A key aspect of the present invention is that each upright is not only inserted into the ground but also secured against being pulled out. This ensures that even when an upward force is exerted on the upright due to buoyancy, it remains correctly anchored. This fixing is also important to guarantee that the bottom seal is pressed firmly against the ground, ensuring that it not only rests on the ground but is also sufficiently compressed.

[0010] Preferably, the locking element is spring-loaded to automatically engage in the locking position. It is particularly important that the post only needs to be inserted into the ground sleeve and, if correctly inserted, anchors itself automatically. This reduces the workload, as locking by the person performing the installation is not required, and also allows for easy verification, as the locking mechanism indicates that the post is properly inserted and secured.

[0011] It is advantageous if the locking element has two opposing tongues. This allows for anchoring on two opposite sides, which further increases the safety of the application and reduces the risk of bending moments.

[0012] A particularly advantageous embodiment of the invention is characterized in that the locking element comprises at least the following parts: a substantially linear spring section, a ramp section arranged obliquely to it, a locking section, and an actuating section. Preferably, the locking element is formed in one piece. It is typically attached to the main body of the upright at the bottom, at the end of the spring section, which extends substantially parallel to the axis of the upright. The ramp section serves to automatically tension the locking element when the upright is inserted into the ground sleeve. The locking section locks the upright when it passes through an opening in the ground sleeve.

[0013] Preferably, the actuating section consists of a tongue that projects upwards when installed. A tool engaging this tongue can first unlock and then pull out a locked stud. The tool tensions the detent element and causes it to retract completely into the stud, thereby releasing axial movement.

[0014] In principle, the upright according to the invention can have any cross-section. However, it has proven particularly advantageous if the upright is tubular with a preferably rectangular cross-section. This allows the locking element to be arranged inside the tube, and there are only two ways to insert the upright into the ground sleeve, these two possibilities being easily distinguishable by the fastening elements attached to the upright. Alternatively, another locking mechanism can be incorporated that allows only one possible position for the upright. Of course, it is also possible for the cross-section of the upright to be square, as a special case of a rectangle.

[0015] Preferably, the locking element is arranged mainly inside the upright, and at least one lateral opening is provided in the upright through which a locking element can partially protrude. The protruding part locks the upright in the ground sleeve.

[0016] A particularly simple embodiment of the present invention provides that the upright has an upper opening through which a release tool can be inserted. This enables quick and easy disassembly of the device.

[0017] A reduction in the total number of components required can be achieved, in particular, by ensuring that the release tool is permanently attached to the upright. This further simplifies warehousing and logistics.

[0018] Preferably, the upright is further provided to have a lower bracket and an upper bracket for wall elements. It is advantageous if the lower bracket is essentially L-shaped. This makes it particularly easy to hook the wall elements onto the bottom.

[0019] It is particularly advantageous if the upper bracket has a locking latch. This allows for tool-free assembly, as the wall elements snap into the upper bracket.

[0020] It is also preferred that the upper bracket is designed to lock a wall element inserted into the lower bracket with the locking latch when the wall element is placed against the upright. The upper bracket also presses the wall element against the floor via an angled surface.

[0021] The present invention also relates to a flood protection system with at least one ground sleeve and a device of the type described above.

[0022] This flood protection system is characterized by the fact that the ground sleeve has a receiving tube for a post. According to the invention, the post can be locked in the ground sleeve. Preferably, at least one wall connection element is also provided, to which a wall element can be attached. In this way, for example, an access road bordered by walls can be secured.

[0023] It is particularly advantageous from a design perspective if the ground sleeve consists of a retaining body in which the receiving tube is embedded. This retaining body is preferably made of concrete. The system's assembly is significantly simplified if the ground sleeve can be closed with a magnetic fastener.

[0024] The invention will now be explained in more detail using a non-limiting embodiment and the accompanying drawings. These show:

[0033] Fig. 8 shows a detail of Fig. 7;

[0034] Fig. 9 Locking elements in various side views; and

[0035] Fig. 10 shows an alternative embodiment of a locking element.

[0036] The device shown in Figures 1 and 2 consists of several wall elements 1, which are held by posts 2 and wall connection elements 3. The posts 2 are inserted into ground sleeves 4.

[0037] The configuration shown serves as an example of how a passageway can be secured. A fixed protective wall 7 is provided laterally, to which a wall connection element 3 is permanently attached. The posts 2 are only inserted into the ground sleeves 4 when needed. Figures 1 and 2 show only two wall elements 1, but the construction can be extended to the right as desired. The wall elements 1 rest on the ground 5, which is preferably asphalted or concreted to ensure the best possible seal.

[0038] As shown in Fig. 3, a ground sleeve 4 consists of a receiving tube 8 cast into a concrete retaining body 6. The upper opening of the receiving tube 8 is closed by an optionally removable cover in the form of a closure 10, which is held magnetically to the receiving tube 8. Ribs 16 secure the anchoring in the retaining body 6. A cover 13 protects the recess 12 from the ingress of concrete during installation of the ground sleeve 4. Sealing strips 14 and 15 further reduce leakage.

[0039] Fig. 5 shows a device according to the invention in its assembled state. Locking elements 11 secure the uprights 2 in the base sleeve 4 by engaging in the recesses 12.

[0040] Figure 5a shows a release tool 17 designed to be inserted from above into a post 2 in order to release it from the base sleeve 4. A wedge element 18 at the lower end is designed to compress the locking elements 11 in order to pull them out of the recesses 12.

[0041] The release tool 17 can be freely removed as needed, but can also be held in the upright 2 in such a way that it is not lost during normal operation.

[0042] Figure 6 shows a detailed view of a stand 2. An upper opening 19 is provided for inserting the release tool 17. Two opposing lateral openings 20 in the stand 2 serve to allow the locking elements 11 to pass through.

[0043] Upright 2 is provided with an upper support 21 and a lower support 22, the latter being essentially L-shaped. A flange 23 limits the penetration of upright 2 into the ground sleeve 4.

[0044] The wall connection element 3 shown in Fig. 7 is similarly equipped with an upper bracket 21 and a lower bracket 22.

[0045] The upper bracket 21 consists of a pressure block 24 and a locking pawl 25, which is pivotable in the direction of arrow 26, and a locking lug 27 serves to secure the wall elements 1. A chamfer 28 in the pressure block 24 facilitates the insertion of the wall elements 1. The locking elements 11 of Fig. 9 have the following sections: a substantially linear spring section 29, a ramp section 33 arranged at an angle to it, a locking section 30, and an actuating section 31 designed in the form of a tongue. The mounting holes 34 arranged in the lower area serve to fasten the locking elements 11 to the upright 2.

[0046] In the embodiment shown in Fig. 10, a one-piece locking element 11 consists of two opposing tongues 32, the construction of which essentially corresponds to a locking element 11 from Fig. 9.
