LIMITING DEVICE AND ORDER

Description

[0001] The invention relates to a limiting device according to the preamble of claim 1. Furthermore, the invention relates to an arrangement of at least two limiting devices.

[0002] Border devices, edging devices, or lawn edges are used to define the boundaries of lawns, flowerbeds, paths, and patios. In addition to being weather-resistant, it is advantageous if the border device can be easily shaped into the desired form and installed quickly and easily.

[0003] DE 523 477 C discloses a flexible lawn edging strip that has tabs at one end and slots at the opposite end. The tabs engage in the slots when installed and are then folded over to connect the strips. The corrugated shape allows the lawn edging strip to be easily bent. These features make it possible for the lawn edging strip to be connected to itself or to another lawn edging strip of the same design.

[0004] DE 20 2017 105377 U1 and US 7 555 863 B1 disclose a limiting device according to the preamble of independent claim 1.

[0005] The familiar lawn edging has the disadvantage that it's simply a plug-in connection, where the tabs must be folded over to prevent them from coming loose. It's possible that the tabs could break if they're bent over repeatedly. Furthermore, folding over the edges requires a lot of effort, which takes time when connecting each lawn edge.

[0006] The present invention is therefore based on the object of providing a limiting device that enables simple and quick assembly without tools and without bending. Furthermore, the object of the invention is to provide an arrangement of at least two limiting devices.

[0007] According to the invention, this object is achieved with regard to the limiting device is solved by the subject matter of claim 1 and the arrangement by the subject matter of claim 14.

[0008] Specifically, the object is achieved by a boundary device, in particular for flowerbeds, gravel, paths, paving, terraces or lawns, comprising a boundary body, in particular a sheet metal / plastic molded part, with a connecting element arranged at a first axial end and a receiving element arranged at a second axial end, wherein the connecting element has at least one tongue extending in a longitudinal direction of the boundary body and the receiving element has at least one tab for receiving the tongue, so that the boundary device can be connected to itself or to another corresponding boundary device.According to the invention, at least one recess is arranged in the region of the first or the second axial end and at least one closure element is arranged in the region of the other axial end, wherein the closure element forms a positive connection, in particular a latching connection, with the recess in the assembled state.

[0009] The limiting device is preferably made of sheet metal. Other materials, such as plastics, are possible.

[0010] The limiting device can be connected to itself or to another limiting device. The various possible applications are discussed in more detail elsewhere.

[0011] The connecting element and the receiving element are arranged at each of the two axial ends. The axial ends are understood to be the end regions of the limiting body. The connecting element interacts with the receiving element and forms a plug-in connection when assembled. The tongue is arranged in the tab. This means that the tongue is at least partially enclosed by the tab, so that movement orthogonal to the longitudinal direction of the limiting body is at least partially blocked.

[0012] The longitudinal direction is understood to mean the direction extending between the first and second axial ends.

[0013] The limiting body additionally has a recess and a closure element, which interact with each other and, when assembled, form a positive connection in the longitudinal direction. The closure element can preferably be designed as a locking element, and the resulting connection can preferably be designed as a locking connection. Consequently, the closure element and the recess prevent displacement, in particular a displacement apart, of the axial ends in a longitudinal direction. As a further advantageous effect, this prevents the formation of gaps.

[0014] The locking element is located at the same axial end as the tabs. Alternatively, the locking element can be located at the same axial end as the tongues. The recess is located at the other axial end.

[0015] The limiting device according to the invention thus has the advantage that a secure connection can be established with a single movement in a longitudinal direction. This means that assembly is possible without additional tools. Furthermore, no bending or screwing is necessary. This enables simplified and accelerated assembly of the limiting device according to the invention.

[0016] Further preferred embodiments are specified in the subclaims.

[0017] In a particularly preferred embodiment, the recess is offset from the tongue and the closure element from the tab, or vice versa, in particular orthogonally offset to the longitudinal direction of the limiting body. As a result, the closure element and the receptacle form an independent connection mechanism separate from the tongues and tabs. As a result, the closure element does not impede the insertion of the tongues into the tabs.

[0018] In a preferred embodiment, the closure element protrudes in a direction orthogonal to the surface of the limiting body. In particular, the closure element protrudes through the recess in the assembled state. This blocks any movement of the limiting device in the longitudinal direction. In other words, the positive connection between the closure element and the recess can be formed.

[0019] It is advantageous if the closure element has a negative slope toward the recess during assembly. In other words, the closure element has an incline. When connecting the axial ends, this reduces the resistance required to push the closure element into the receptacle. In other words, the incline allows the closure element to slide into the receptacle.

[0020] To further improve this property, the closure element is curved at least in sections. A curvature of the closure element means that the closure element has a cross-sectional curve. The curvature also prevents a person from injuring themselves on the protruding closure element.

[0021] It is possible to have an opening on the side of the locking element that faces away from the recess during assembly. This opening makes it easier to push in the locking element, making it easier to release the connection if necessary.

[0022] In a particularly preferred embodiment, the connecting element has at least two, in particular three, tongues, and the receiving element has at least two, in particular three, tabs. The arrangement of the plurality of tongues and tabs at the axial ends ensures that the axial ends are tightly and flatly connected to one another.

[0023] In a further particularly preferred embodiment, the at least one tab protrudes in a direction orthogonal to the surface of the limiting body and has a through opening extending in the longitudinal direction of the limiting body.

[0024] In a further preferred embodiment, the connecting element has a step and the connecting element is offset from the surface of the limiting body by the step.

[0025] The protruding tab and the connecting element, which is offset from the surface of the limiting body by the step, allow the tongue to be inserted into the tab without the two axial ends 13, 15 getting in each other's way.

[0026] According to the invention, the connecting element is arranged in a connecting plane, wherein the connecting plane extends parallel and offset to a surface of the boundary body, and wherein the receiving element is adapted to interact with the connecting element such that the boundary body can be connected butt-jointly. This configuration is advantageous because it reduces the formation of gaps. Specifically, the offset connection makes it possible to arrange the ends of the boundary body(s) butt-jointly. Particularly preferably, the connecting element overlaps at least partially or completely with the second axial end, which is butt-jointly connected to the first axial end. This overlap prevents or at least reduces the formation of gaps. Furthermore, a flush surface is achieved in this way. This prevents soil or grass from penetrating through it. Furthermore, an attractive visual impression is achieved.

[0027] In an advantageous embodiment, the limiting body has a linear perforation extending orthogonally to the longitudinal direction of the limiting body. The limiting body can be easily bent along the perforation. In particular, the limiting body can be bent at an angle. This allows for angular structures with one or more limiting devices.

[0028] It is advantageous if the boundary body has at least one fastening element that rests on a floor surface when installed, in particular is screwed, nailed, and / or anchored to the floor surface. This facilitates the positioning of the boundary devices during installation. In particular, this allows the boundary device to be fixed in the floor during installation, preventing subsequent displacement.

[0029] It is further advantageous if the limiting device is manufactured in one piece, particularly monolithically. This allows for savings in manufacturing costs.

[0030] For weather resistance, the barrier device is preferably made of galvanized steel, stainless steel, and / or CorTen steel. Other materials, such as plastics, are also possible.

[0031] Within the scope of the invention, an arrangement with at least two limiting devices is further disclosed and claimed.

[0032] The invention is explained in more detail below using exemplary embodiments with reference to the accompanying drawings.

[0034] In Fig. 1 A limiting device 10 is shown with a limiting body 11 having a first axial end 13 and a second axial end 15. A connecting element 12 is arranged at the first axial end 13, and a receiving element 14 is arranged at the second axial end 15.

[0035] Fig. 2 shows the first and second axial ends 13, 15 in comparison. Fig. 3 shows the two axial ends 13, 15 in the connected state. These can be two different limiting devices or a single limiting device 10.

[0036] The limiting body 11 has a bent or folded portion. The folded portion is located on a side that is positioned at the top when installed. The folded portion extends along the entire longitudinal axis of the limiting body 11. More specifically, the folded portion extends from the second axial end 15 to the connecting element 12.

[0037] The connecting element 12 is separated from the limiting body 11 by a step 22. In other words, the connecting element 12 lies on a plane parallel to the surface of the limiting body 11.

[0038] The connecting element 12 has three tongues 16 extending in a longitudinal direction of the limiting body 11. The tongues 16 are spaced apart from each other in the transverse direction.

[0039] A transverse direction is understood to mean a direction orthogonal to the longitudinal direction of the boundary body and parallel to a surface of the boundary body 11. The surface is understood to mean the area that is arranged vertically in the installed state.

[0040] The tongues 16 each have two recesses 27 that delimit the tongues 16 in the transverse direction. The recesses 27 and the tongues 16 have a rectangular geometry. Alternatively, other shapes and a different number of tongues 16 and recesses 27 are conceivable.

[0041] The connecting element 12 interacts with the receiving element 14. For this purpose, the receiving element 14 comprises three tabs 17, which are arranged corresponding to the tongues 16 in the region of the second axial end 15. A different number of tabs 17 is conceivable, depending on the number of tongues 16.

[0042] One of the tabs 17 is in Fig. 5 shown in detail. The tabs 17 are bridge-shaped. Specifically, the tabs 17 have a through-opening 21 in the longitudinal direction of the limiting body 11. The tabs 17 are each connected to the limiting body 11 in the transverse direction by connecting sections. The tabs 17 are preferably formed from the material of the limiting body 11. This means that the tabs 17 and the limiting body 11 are monolithic.

[0043] Fig. 3 shows the arrangement according to Fig. 2 in the connected state. Here, it can be seen that the connecting sections of the tabs 17 are arranged in the recesses 27 in the assembled state and that the tongues 16 are arranged in the through openings 21 of the tabs 17.

[0044] The connecting element 12 comprises a rectangular recess 18. The recess 18 is arranged between two tongues 16. Specifically, the recess 18 is arranged between the two lower tongues 16 when installed. Alternatively, other shapes and multiple recesses 18 are possible.

[0045] In the area of ​​the second axial end 15, a closure element 19 is arranged between two tabs 17. Another arrangement of the closure element is possible, for example, starting from the second axial end behind the tabs or, in the installed state, below or above the tabs. The closure element 19 and the recess 18 are each arranged correspondingly, so that the closure element 19 is arranged in the recess 18 in the connected state. Several closure elements 19 and recesses 18 are possible. A detailed view of the closure element 19 and the recess 18 in the connected state is shown in Fig. 4 shown.

[0046] The closure element 19 is designed as a protruding structural element. The closure element 19 has an inclination. The inclination begins on the side of the closure element 19 facing the second axial end 15. The inclination increases toward the first axial end 13. The closure element 19 has a curvature in cross-section. In the assembled state, the closure element 19 protrudes at least partially from the recess 18.

[0047] An opening 20 borders the closure element 19. The opening 20 is arranged on the side of the closure element 19 facing away from the second axial end 15. In the connected state, the opening 20 is partially covered by the connecting element 12.

[0048] Fig. 7 shows a view of two interconnected limiting devices 10 of the type described above. Alternatively, it is possible that, as in Fig. 10 shown the axial ends 13, 15 of a single limiting device 10 are connected to each other and the limiting device 10 limits a circular area.

[0049] As in Fig. 8 As shown, the limiting body 11 may have one or more perforations 23. The limiting body 11 in Fig. 8 has four perforations 23. The perforations 23 each extend along a transverse direction of the boundary body 10. The perforation 23 allows the boundary body 11 to be bent more easily at predefined locations. The perforations 23 in Fig. 8 are distributed on the limiting body 10 in such a way that the limiting device 10 can be formed into a rectangle.

[0050] In Fig. 11 several limiting devices 10 according to Fig. 8 , each of which was shaped into a rectangle and arranged to form a honeycomb structure. A different distribution of the perforations 23 on the boundary body 10 to allow for other shapes is not excluded.

[0051] In Fig. 9 is a limiting device 10 according to Fig. 1 shown, which has fastening elements 24. The fastening elements 24 are arranged on a lower side of the limiting body 11 in the installed or laid state. The fastening elements 24 extend orthogonally to the surface of the limiting body 11. More precisely, the fastening elements 24 are designed as projections of the limiting body 11 that are angled by 90°. The angle refers to the surface of the limiting body 11 that is vertically aligned in the installed state. In the exemplary embodiment shown here, the limiting body 10 comprises seven fastening elements 24. More or fewer fastening elements 24 are possible. The fastening elements 24 each have a fastening opening. The limiting device 10 can be fastened, in particular anchored or screwed, to a floor through the fastening opening.

[0052] Fig. 12 shows a combination of a limiting device 10 without perforations 23 and a limiting device 10 with perforations 23. The limiting device 10 without perforations 23 is arranged in a circular arc, while the limiting device 10 with perforations 23 has multiple angles. By combining the described limiting devices 10, many different shapes are possible. The limiting device 10 can therefore be adapted to various circumstances or requirements.

[0053] The folded area has two functions. Firstly, the folded area prevents the limiting body 11 from having any sharp edges that could injure a person when installed. Furthermore, the folded area forms a gap 25. This gap 25 serves as a guide for the connecting element 12. For this purpose, the connecting element 12 has a guide element 26. The guide element 26 extends upward when installed. In the installed state, the guide element 26 is completely arranged in the gap 25, and the folded areas of the first and second axial ends lie closely against one another.

[0054] In Fig. 6The step 22 can be seen in detail. The step 22 separates the connecting element 12 from the limiting body 11. Due to the step 22, the connecting element 12 is offset parallel to the surface of the limiting body 11. This means that the axial ends 13, 15 can be connected to one another butt-to-butt, so that no gap is formed. Furthermore, the tongues 16 are arranged at the level of the through-openings 21 of the tabs 17, and the recess 18 can be moved over the closure element 19 to form the locking connection.

[0055] The tongues 16, in combination with the lugs 17, enable simple and quick assembly. This means that the two axial ends 13, 15 are simply moved toward each other along a longitudinal direction to connect them. The tongues 16 are only movable in the longitudinal direction within the lugs 17.

[0056] The recesses 27 allow the tongues 16 to be fully inserted into the through-openings 21 of the tabs 17. As a result, the connecting element 12 overlaps the second axial end 15 in the assembled state, so that the second axial end 15 is butt-connected to the first axial end 13, at which the connecting element 12 is arranged offset in parallel.

[0057] The closure element 19, together with the recess 18, forms a locking connection. In the connected or assembled state, the locking connection fixes the two axial ends 13, 15 in a longitudinal direction, in particular in a longitudinal direction facing away from the respectively connected axial end 13, 15. The movement of the two axial ends 13, 15 toward each other in a longitudinal direction is additionally limited by the recesses 27 on the tongues 16. More precisely, the recesses 27 form stops for the tabs 17. Because the limiting body 11 is fixed by the guide element 26 and the tongues 16 and tabs 17 in a direction orthogonal to the longitudinal direction, the closure element 19 remains in the receptacle 18.

[0058] The inclination of the locking element 19 causes it to easily snap into the recess 18. This effect is supported by the curvature of the locking element 19. The curvature also prevents sharp edges that could cause injuries. The opening 20 allows for greater elasticity of the locking element 19. In other words, the locking element 19 can be pressed in more easily to release the connection.

[0059] The combination of the plug-in connection and the snap-in connection enables a positive connection between the axial ends 13, 15 of one or more limiting devices 10, which is fixed in all degrees of freedom. The connection can be implemented without tools or bending. Assembly is particularly simple, since a movement of the two axial ends 13, 15 in the longitudinal direction is sufficient for connection. In other words, no rotation or changing of the position or angle with respect to the longitudinal direction of the limiting body 11 is necessary for connection.

[0060] Specifically, for connection, the two axial ends 13, 15 of one or two limiting devices are positioned opposite one another. The guide element 26 is arranged in the gap 25 of the folded area to correctly align the axial ends 13, 15. Subsequently, the two axial ends 13, 15 are moved toward each other in the longitudinal direction so that the tongues 16 are inserted into the through-opening 21 of the tabs 17 and the closure element 19 is snapped into the recess 18.
