Description

[0001] The invention relates to a fence post for a fence strut of a railway protection fence formed from several such fence posts according to the preamble of claim 1, a fence strut for a railway protection fence according to claim 12 and a railway protection fence system according to claim 14.

[0002] To secure (temporary) track construction sites, track protection fences or track bed protection fences are used in railway traffic to prevent unintentional intrusion into a track area, for example, an intrusion into the area of ​​a track that is still in use.

[0003] EP 3 936 663 A1 discloses a rail protection fence system comprising a rail protection fence having at least one fence brace. The rail protection fence is attached to a track system, specifically to a rail of the track system, via rail protection fence support systems. The rail protection fence support system comprises a fence support for supporting the at least one fence brace, a fastening element that can be fastened to a track system, and a fixing system for fixing the fence support to the fastening element. The fence braces forming the rail protection fence are each formed by a plurality of braces, with adjacent braces being connected to one another by a brace connector that is inserted into the mutually facing ends of the braces.

[0004] To connect the fence posts of such continuous fence struts known from the prior art, the posts or fence posts are usually connected to one another in sequence by inserting a post connector into the preceding post and pushing the subsequent post onto the post connector. Accordingly, the posts are usually separated step by step. Connecting and separating posts arranged centrally within a fence strut, for example in order to temporarily create access to a safety-critical area at one point on the railway fence, is problematic and complex. This is particularly true because adjacent posts prevent the posts to be separated from being moved axially, i.e. along the longitudinal axis of the fence strut.

[0005] Based on this, the objective is to provide a fence post for a railroad safety fence consisting of several such fence posts, which allows for easy assembly and disassembly of the fence posts, especially centrally installed fence posts. Furthermore, a fence post consisting of several fence posts and a railroad safety fence system comprising at least one fence post are to be provided.

[0006] This object is achieved with a fence post according to claim 1, a fence strut according to claim 12 and a track protection fence system according to claim 14. Advantageous embodiments and expedient further developments of the invention can be found in the subclaims.

[0007] The fence post according to the invention for a fence strut of a railway track protection fence formed from a plurality of such fence posts has a pole connector at a first end which is arranged on the fence post so as to be displaceable between an extended coupling position for connection to an adjacent fence post and a release position retracted into the fence post for releasing adjacent fence posts of a fence strut. The fence posts preferably comprise tubes with a substantially round or rectangular, in particular square, cross-section, with the pole connector being guided internally at the first end. The pole connector is displaced axially, i.e. parallel to the longitudinal axis of the fence post. For connection to an adjacent fence post, the pole connector is inserted in the coupling position into an end of the adjacent fence post designed to receive the pole connector.The design according to the invention makes it possible to connect and disconnect the fence posts without axial displacement of the fence posts to be connected or separated. Specifically, to disconnect two interconnected fence posts, the post connector connecting the fence posts is moved into the retracted release position. This allows the fence posts to be moved apart, in particular transversely to the longitudinal axis of the fence brace. The disconnected fence posts from the remainder of the fence brace still connected to the other end of the fence post, i.e. from another fence post connected to the other end of the fence posts via a post connector, can be done either analogously to the above-described retraction of the post connector into the release position.Because the fence posts have already been separated, they can also be detached from the rest of the fence brace by axially moving them along the longitudinal axis of the fence brace. Connecting adjacent fence posts, especially fence posts to be connected internally within an assembled fence brace, can be achieved by appropriately moving the post connector from the release position to the coupling position and inserting the post connector into the adjacent fence post. The inventive design enables simple and rapid connection and disconnection of adjacent fence posts, especially fence posts arranged internally within a fence brace.

[0008] In an advantageous embodiment, the fence post has a connecting section at a second end, in particular a connecting section that is tapered compared to the rest of the fence post, i.e., has a reduced dimension or diameter, or alternatively is widened, for connection to the post connector of an adjacent, similar fence post. Preferably, the connecting section is designed for inserting the post connector of an adjacent fence post, in particular for positively receiving the post connector. By designing the fence post with the post connector at the first end and the connecting section at the second end, several of these fence posts can be connected to one another to form a fence brace.Preferably, the rod connector and the connecting section each have at least one receiving opening, which are arranged concentrically when the rod connector is connected to the connecting section. To securely connect the rod connector and the connecting section, a securing element, for example a securing pin, can be inserted into the receiving openings arranged one above the other. This ensures a secure connection of adjacent fence rods, reliably preventing, in particular, unwanted lateral movement and the resulting loosening of adjacent fence rods. In a particularly advantageous embodiment, the rod connector has an engagement section, which preferably has a smaller dimension than the rest of the rod connector, specifically a smaller (outer) diameter.In the coupling position, the engagement section engages into the connecting section of an adjacent fence post, with a shoulder delimiting the engagement section being located on the outer edge of the connecting section.

[0009] The recess at the outer edge limits the penetration depth of the rod connector. Furthermore, this design also ensures that the receiving openings in the engagement area of ​​the rod connector and the receiving openings in the connecting section for inserting a securing element are positioned in a correspondingly superimposed position.

[0010] In a further advantageous embodiment, the pole connector is spring-loaded in the coupling position or the release position. The spring-loaded preload of the pole connector in one of the aforementioned positions is particularly advantageous for connecting and / or releasing adjacent fence poles. Preferably, the pole connector is preloaded in the coupling position, which represents the basic position, so that the spring-loaded preload alone holds the pole connector in the coupling position, which connects two adjacent fence poles. In a particularly advantageous embodiment, a limiting element is arranged in the fence pole, and a spring element is arranged between the limiting element and the pole connector. The limiting element can in particular be a limiting pin inserted into the fence pole.The above-mentioned design provides a particularly simple and robust design of a rod connector that is spring-loaded in the fence rod.

[0011] Preferably, the pole connector is fully or at least almost fully inserted into the fence pole in the release position. The pole connector, positioned in the release position, does not impede the connection or disconnection of two fence poles.

[0012] In a preferred embodiment, an actuating element connected to the rod connector is provided for, in particular, manually moving the rod connector from the coupling position to the release position and / or from the release position to the coupling position. The rod connector can preferably be moved directly via the actuating element. No further, in particular special, tool is required for this purpose. The actuating element enables a user to easily move the rod connector from the coupling position to the release position or vice versa. Particularly preferably, the actuating element is guided in a guide slot of the fence rod, in particular from the rod connector arranged displaceably inside the fence rod through the guide slot to the outside.The guide slot is preferably designed as an elongated hole extending along the longitudinal axis of the fence post. The guide slot, especially the engagement of the actuating element at the ends of the guide slot, can limit the displacement of the actuating element and thus the displacement of the post connector. In particular, displacement of the post connector beyond the coupling position and / or the release position can be prevented.

[0013] The pole connector can, for example, be a substantially cylindrical solid body. To prevent the spread of charge over long distances along the cordoned-off area or along the fence strut, the pole connector is preferably designed to be electrically insulating, for example, molded from a plastic.

[0014] The invention further relates to a fence brace for a railway protection fence comprising several fence posts described above, in particular similar ones, wherein adjacent fence posts are detachably connected to one another via a post connector engaging both fence posts. Preferably, the interconnected fence posts are secured by a securing element that can be inserted into receiving openings in the fence post and the post connector.

[0015] The invention also relates to a railway track protection fence system comprising a fence strut as described above and a railway track protection fence holding system which can be attached to a rail and has at least one fence bracket which has at least one, preferably several suspensions into which the fence strut can be inserted and secured. The suspensions preferably have a pole holder which is adapted to the outer contour of the fence poles and into which the fence strut, or the fence poles connected to one another to form the fence strut, can be inserted from above and then secured by a securing unit which prevents removal from the pole holder, in particular a securing unit which limits the opening of the pole holder. The fence struts are preferably clamped in the pole holders. By clamping the fence poles of the fence strut to the fence brackets and by connecting several fence poles, the railway track protection fence is stiffened.of the rail protection fence system. The stiffening provides the rail protection fence system with great stability along its course parallel to the rail.

[0016] These and other features, as well as advantages and effects, of the fence post according to the invention and the fence strut formed therefrom for a railway fence system are evident from the following embodiments described in more detail with reference to the accompanying drawings. The drawings show: Fig. 1 a track protection fence system comprising a track protection fence formed from several fence struts and a track protection fence holding system attached to a rail; Fig. 2 a side view of a rail protection fence support system from Fig. 1; Fig. 3 a detailed view of a suspension of a fence bracket of the railway protection fence system from Fig. 2; Fig. 4 a section of a fence post of the rail fence from Fig. 1 in a side view; Fig. 5 a section of a fence post of the rail fence from Fig. 1 in a sectioned side view; Fig. 6 an enlarged view of the fence post from Fig. 5 with rod connector arranged in the coupling position; Fig. 7 an enlarged view of the fence post from Fig. 5 with rod connector arranged in the release position; Fig. 8 a sectional side view of two adjacent fence posts of a fence brace in an unconnected, detached state; Fig. 9 a sectional side view of two adjacent fence posts of a fence brace in a connected, unsecured state; Fig. 10 a sectional side view of two adjacent fence posts of a fence brace in a connected, secured state.

[0017] Fig. 1 shows a perspective view of a rail protection fence system 1 comprising several rail protection fence support systems 2, via which a rail protection fence is attached to a rail 3, which is sketched here in the form of short rail sections. Fig. The track protection fence holding system 2 shown in Fig. 2 comprises a rail foot holder 4 attached to the rail 3, a horizontal strut arrangement 5 attached to the rail foot holder 4 and a fence holder 6 connected to the horizontal strut arrangement 5.

[0018] The Fig. 1, the exemplary rail protection fence is formed by three superimposed fence struts 7, which are held by correspondingly superimposed suspensions 8 of the fence brackets 6. The exemplary fence brackets 6 are, as in particular also in Fig. 2, each of which is composed of several vertical struts that are inserted into one another and guided, and whose position can be fixed relative to one another by means of fixing means, here using wing screws. The attachment of the suspensions 8 to the vertical struts of the fence bracket 6 can be achieved, for example, by welding or screwing. The fence struts 7 that can be arranged in the suspensions 8 are each composed of interconnected fence poles 9, which are described in detail below. For illustrative purposes only, the uppermost fence strut 7 is shown in Fig. 1 is shown incompletely or with only one fence post 9. Accordingly, in Fig. 2 shows the uppermost suspension 8 of the fence bracket 6 without a fence pole 9 inserted into it. In the present embodiment, the fence poles 9 have a round cross-section, although other designs are also possible in principle.

[0019] Fig. 3 shows a suspension 8 of the fence bracket 6 from Fig. 1 and Fig. 2 in an enlarged view. The suspension 8 comprises a pole holder 10 which is adapted to the outer contour of the fence pole 9 and open at the top, a rotatably mounted clamping block 11 and a wing nut 12 arranged in a threaded holder. The fixing of a fence pole 9 inserted into the pole holder 10 from above is achieved by screwing the wing nut 12 in the direction of the pole holder 10. In particular, the front end of the wing nut 12 presses against the clamping block 11 so that the latter comes into contact with the fence pole 9 inserted into the pole holder 10 and clamps it in the pole holder 10.

[0020] The two end areas of a fence post 9 of the fence brace 7 made of Fig. 1 are in Fig. 4 and in Fig. 5 in a side view, where Fig. 5 one opposite Fig. 4 shows a sectional view rotated by 90°. The fence post 9 can, as indicated by the vertical lines, have any length that is reasonably manageable by a user and provides the required stability.

[0021] At the Fig. 4 and Fig. 5 shown and in Fig. 6 and in Fig. 7, a particularly electrically insulating pole connector 13 is arranged. The pole connector 13 is arranged between a Fig. 6 shown extended coupling position, via which the fence pole 9 can be connected to an adjacent fence pole 9, and one in Fig. 7, in which the pole connector 13 is fully inserted into the fence pole 9, is slidably guided in the fence pole 9. In the exemplary embodiment shown here, the pole connector 13 is pretensioned in the coupling position forming the basic position by a spring element 14 arranged in the fence pole 9. The spring element 14 rests with one side on the inner end of the pole connector 13 located in the fence pole 9 and with its other side on a limiting element 15 arranged in the fence pole 9. The limiting element 15 of the exemplary embodiment shown is specifically, as also in Fig. 4, is formed by a limit pin inserted through the side wall of the fence post 9.

[0022] Via an actuating element 16 connected to the rod connector 13, the rod connector 13 can be moved from the Fig. 6 shown coupling position against the action of the spring element 14 into the Fig. 7. The actuating element 16 of the illustrated embodiment is designed as an actuating pin inserted into a receptacle of the rod connector 13, wherein the actuating pin is guided outwardly through a guide slot 17 of the fence rod 9 extending along the longitudinal axis of the fence rod 9. By the actuating element 16 resting against the longitudinal ends of the guide slot 17, the displacement path of the rod connector 13 is limited. Specifically, the positions in which the actuating element 16 rests against the longitudinal ends of the guide slot 17 represent the coupling position and the release position, respectively, in the illustrated embodiment.

[0023] For below in relation to Fig. 8 to Fig. 10 in detail described connecting two similar adjacent fence poles 9 with the help of the pole connector 13, the fence pole 9 has the in Fig. 4 and Fig. 5 has a connecting section 18. In the present embodiment, the connecting section 18 has a reduced diameter compared to the rest of the fence pole 9. An engagement section 19 of the pole connector 13, which projects outwards in the coupling position, can be introduced into the connecting section 18. The engagement section 19 has a reduced diameter compared to the rest of the pole connector 13, forming a shoulder 20, wherein the outer diameter of the engagement region 19 substantially corresponds to the inner diameter of the connecting section 18. The connecting section 18 and the engagement region 19 of the pole connector 13 further have receiving openings 21, into which, as described below with reference to Fig. 10 is described in more detail, a securing element 22 can be introduced to secure the connection of adjacent fence poles 9.

[0024] In Fig. 8 to Fig. 10 shows the connection of two adjacent fence poles 9, 9', specifically the connection of the pole connector 13 of a first fence pole 9 with a connecting section 18' of a second fence pole 9'. As shown in Fig. 8, the rod connector 13 of the first fence rod 9 is first moved into the release position via the actuating element 16, and the connecting section 18' of the second fence rod 9' and the end of the first fence rod 9 having the rod connector 13 are positioned adjacent to each other. Under the action of the spring element 14, optionally supported by actuating the actuating element 16, the rod connector 13, as shown in Fig. 9, then moved into the coupling position, whereby the engagement area 19 of the rod connector 13 is moved into the connecting section 18' of the Fig. 9 left fence pole 9'. When the engagement section 19 is fully inserted into the connecting section 18', the shoulder 20 rests against the outer edge of the connecting section 18'. The receiving opening 21 of the engagement area 13 and the receiving opening 21' of the connecting section 18' are concentric to each other. To secure the fence poles 9, 9' in the coupled state, as shown in Fig. 10, a securing element 22, in the present case in the form of a pipe clip, is inserted into the receiving openings 21, 21'. The two interconnected fence poles 9, 9' are released in the reverse manner.

[0025] For the sake of completeness, it should be noted that the present invention is not limited to the exemplary embodiment shown here. For example, fence struts 7 and pole connectors 13 with a square cross-section are also conceivable. Furthermore, other configurations of the horizontal strut arrangement 5 and the fence bracket 6 are also conceivable, such as struts with a round or other cross-sectional shape.
