Description

[0001] The invention relates to a climbing aid for guardrail arrangements with a ladder body containing a step and a handrail.

[0002] From DE 10 2016 003 871 B4 a climbing aid for a mesh fence is known, which has a tread surface with several slots for engaging the longitudinal struts of the mesh fence.

[0003] Linetech GmbH & Co. KG is known to offer a climbing aid, model LT 904, for concrete barriers, which features a ladder body with a step and a handrail. The ladder body is a single piece and is secured to the concrete wall using fasteners.

[0004] The object of the present invention is to provide a climbing aid for guardrail arrangements in such a way that climbing over the guardrails is ensured in a simple manner.

[0005] To solve this problem, the invention in conjunction with the preamble of claim 1 is characterized in that the ladder body has a first body part and a second body part connectable to the same, wherein the ladder body can be placed on a top side of the guardrail in a mounting position of the first body part and the second body part forming a U-shaped profile.

[0006] The particular advantage of the invention lies in the fact that a climbing aid can be easily and quickly mounted and dismounted on a guardrail without the need for tools to lock the climbing aid in place. Advantageously, once the climbing aid is placed on the guardrail assembly, a defined mounting position can be assumed, in which easy climbing over is made possible for one person.

[0007] According to a preferred embodiment of the invention, a first body part and a second body part of the climbing aid are pivotably connected to each other. Due to the pivotable arrangement of the two body parts of the climbing aid and the U-shaped profile, the climbing aid can be easily and quickly placed onto the guardrail from above by opening the two body parts. Due to the weight of the two body parts, they rest against opposite upright walls (sides) of the guardrail, so that the climbing aid is immediately ready for use in this assembled position. By integrating a handrail and at least one step, a person can safely cross the guardrail from one side to the other.The foldable climbing aid can be advantageously used for maintenance and new construction work, as well as by police, fire brigade and rescue services when crossing, for example, a median strip of a motorway.

[0008] According to a preferred embodiment of the invention, the climbing aid has a pivot bearing by which the first body part is pivotably or foldably connected to the second body part. The pivot bearing is preferably arranged at one end of a vertex and / or in a connection area of ​​the vertex with a first and / or second leg of the U-shaped profile of the climbing aid, so that, in the installed position of the climbing aid, an axis of rotation of the pivot bearing is located on an upper side or upper corner area of ​​the guardrail. This ensures simple installation, as the climbing aid, with its pivotable body parts, essentially slips over the guardrail.

[0009] According to a further development of the invention, the length of the apex of the climbing aid is adapted to the width of the guardrail, and in particular, the length of the apex is equal to or greater than the width of the guardrail or several guardrail types, so that the climbing aid can be used for different guardrail widths or guardrail types. Preferably, the apex is straight, so that it extends over the entire width of the guardrail, i.e., from one edge of a top surface of the guardrail to an opposite edge of the same top surface, or lies against it in a linear or planar manner.

[0010] According to a preferred embodiment of the invention, the first body part and / or the second body part of the climbing aid has projecting stop struts on their mutually facing sides, which, in the installed position, abut or rest against upright walls, sides, or parts of the guardrail. This ensures a defined installation position of the climbing aid, since the free ends of the stop struts press against the guardrail due to the weight of the first body part or second body part.

[0011] According to a further development of the invention, the second body part has an angled section that includes a tread surface offset parallel to the apex of the U-shaped profile. This ensures comfortable passage over super-rail guardrails, where several guardrails are arranged laterally and vertically offset from one another.

[0012] According to a further development of the invention, the second body part comprises a tread surface element and a step element, which are essentially perpendicular to each other. In the installed position, the step element has a projecting section with a contact surface on a side facing the first body part, so that the step element assumes a vertical position in the installed position. The stop element is arranged in such a region of the step element that it supports the step element against a guardrail or barrier, thus ensuring the step element assumes a vertical position. The vertical position of the step element is essentially ensured by its own weight, with the contact surface supporting it against the guardrail or barrier. Advantageously, a defined installation position of the second body part can be set in this way.

[0013] According to a further development of the invention, the first body part comprises a step element provided with a stop section. In the installed position, the stop element rests against the guardrail or support post with a stop surface in such a way that the step element assumes a defined vertical position.

[0014] According to a further development of the invention, the first body part is integrally connected to the second body part via a pivot joint, the pivot joint having the axis of rotation about which the body parts are arranged to pivot relative to each other. Advantageously, this allows the climbing aid to be easily assembled and disassembled, with the climbing aid being securely positioned on the guardrail in the assembled position via the U-shaped profile.

[0015] According to an alternative embodiment of the invention, the first body part is detachably connected to the second body part. Advantageously, the effort required for assembling and disassembling the climbing aid is reduced, since only the first body part and then the second body part need to be attached to the guardrail assembly one after the other.

[0016] According to a further development of the invention, the first body part is connected to the second body part in the assembled position via a hook connection. Advantageously, the first body part can be mounted by placing the U-shaped profile on the guardrail, preferably without it being able to move perpendicular to the guardrail. The second body part can be attached to the mounted or suspended first body part by a clamping, snap-fit, or screw connection, so that a U-shaped ladder body is formed which has steps on both sides for climbing over the guardrail assembly.

[0017] According to a further development of the invention, the second body part has at least one adjustment element by means of which a width compensation of the ladder body for different guardrail arrangements is ensured. The adjustment element causes a change in a stop section of the second body part, so that the second body part can be positioned at a different distance from the first body part in the installed position. Advantageously, this allows a different width of the ladder body or the distance between its two legs to be adjusted relative to each other, so that the climbing aid can be used for different guardrail arrangements, in particular for guardrail arrangements of different horizontal widths.

[0018] According to a further development of the invention, the adjusting element is designed such that it can assume two adjustment positions. In a first adjustment position, the adjusting element enlarges the stop section and itself forms a protruding stop surface. In this way, adaptation to relatively narrow guardrail arrangements is ensured. In a second adjustment position, the adjusting element is arranged such that it does not enlarge the stop section, so that the stop section itself forms the stop surface for the guardrail arrangement. Advantageously, the climbing aid can thus be used for a relatively wide guardrail arrangement.

[0019] Further advantages of the invention will become apparent from the further dependent claims.

[0020] Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

[0021] They show: Figure 1 shows a perspective view of a climbing aid according to a first embodiment in a mounting position on a guardrail arrangement (Super-Rail guardrail) as seen from a first body part of the climbing aid; Figure 2 shows a perspective view of the climbing aid in its mounting position according to Figure 1Figure 3 shows a side view of the climbing aid according to the first embodiment in its mounted position on the guardrail assembly (Super-Rail guardrail), Figure 4 shows a side view of the climbing aid according to the first embodiment in a transport position, Figure 5 shows a side view of a climbing aid according to a second embodiment in an upright position, Figure 6 shows a side view of the climbing aid according to the second embodiment in a mounted position on a guardrail assembly of the first type (Super-Rail guardrail ECO),Figure 7 shows a side view of the climbing aid according to the second embodiment in the mounted position on a guardrail assembly of a second type (Super-Rail guardrail ECO H5), and Figure 8 shows a side view of the climbing aid according to the second embodiment in the mounted position on a guardrail assembly of a third type (Super-Rail guardrail).

[0022] A climbing aid for guardrail arrangements according to the invention consists, according to a first embodiment of the invention, of the Figures 1 to 4 consisting of a conductor body 1 comprising a first body part 2 and a second body part 3 pivotably arranged relative to the first body part 2. The first body part 2 and the second body part 3 are preferably integrally connected.

[0023] The conductor body 1 is U-shaped. In a Figure 3In the depicted transport position, a free end 4 of the first body part 2 abuts a free end 5 of the second body part 3.

[0024] To obtain the in the Figure 1 and 2 In the illustrated assembly position of the ladder body 1 or the climbing aid, the first body part 2 and the second body part 3 are unfolded and, with a U-shaped profile 6 of the ladder body 1 attached to a first guardrail 7, are placed on the same.

[0025] In the present embodiment, the first body part 2 is pivotally connected to the second body part 3 via a pivot bearing. In the installed position of the ladder body 1, a rotation axis D of the pivot bearing runs parallel to the direction of extension of the first guardrail 7.

[0026] The pivot bearing or pivot axis D is arranged in the region of a vertex 8 of the U-shaped profile 6. In the present embodiment, the pivot bearing or pivot axis D is arranged at one end of the vertex 8 or in a connection area of ​​the vertex 8 to a second leg 10 of the U-shaped profile 6 opposite a first leg 9 of the U-shaped profile 6. In this way, the pivot bearing or pivot axis D is arranged in an upper corner region of the first guardrail 7 in the assembly position. This allows the ladder body 1 to be easily unfolded for assembly by unfolding the first body part 2 and the second body part 3 and placed onto the first guardrail 7 from above, so that subsequently, the assembly position is achieved by the first body part and the second body part 3 preferably folding together automatically due to their own weight. Figure 1 and 2is taken.

[0027] In the present embodiment, the first body part 2 has the U-shaped profile 6. In the assembled position, the apex 8 of the U-shaped profile 6 rests on a top surface 11 of the first guardrail 7. The first leg 9 of the U-shaped profile 6 rests against a first upright side 12 of the first guardrail 7, and the second leg 10 rests against a second upright side 13 of the first guardrail 7, which is offset parallel to the first upright side 12.

[0028] In the present embodiment, the first guardrail 7 has a U-shaped cross-section, wherein the second upright side 13 is formed by a wall and the first upright side 12 by a plane in which the free ends of the first guardrail 7 run.

[0029] A length l S of the apex 8 is equal to or greater than a width b of the first guardrail 7. In this way, it is ensured that the conductor body 1 is arranged without tilting on the first guardrail 7.

[0030] In the present embodiment, the length lS of the apex 8 corresponds to the width b of the first guardrail 7, so that the first leg 9 and the second leg 10 of the U-shaped profile 8 also bear against the first upright side 12 and the second upright side 13 of the first guardrail 7, respectively, in a line and / or surface contact. The conductor body 1 encompasses the first guardrail 7 essentially without play from three different sides. The first upright side 12 and the second upright side 13, which run parallel to each other, are perpendicular to the top surface 11 of the first guardrail 7. The first leg 9 and the second leg 10 of the U-shaped profile 6, which run parallel to each other, are straight and perpendicular to the apex 8 of the U-shaped profile 6.

[0031] In the present embodiment, in addition to the first guardrail 7, a second guardrail 17 is provided, wherein the second guardrail 17 is arranged horizontally and vertically offset from the first guardrail 7.

[0032] The first guardrail 7 and the second guardrail 17 are attached to a common guardrail post 18, with the first guardrail 7 and the second guardrail 17 running horizontally. The second guardrail 17 also has a U-shaped cross-section.

[0033] An additional guardrail 19 is attached to the second guardrail 17, which, for example, delineates one lane of a motorway or expressway. The first guardrail 7, the second guardrail 17, and the guardrail 19 together form a guardrail assembly of a specific type, known as a super-rail guardrail. The super-rail guardrail 7, 17, 19 can, for example, be arranged to delineate two lanes in a median strip of an expressway or motorway.

[0034] To ensure that the ladder body 1 additionally surrounds or encompasses the second guardrail 17 and the guardrail 19, the second body section 3 has a tread section 21 which is pivotally connected to the first body section 2 via a pivot bearing by means of a pivot section 15. A tread 16 adjoins the pivot section 15, which is intended for a person to climb onto and stand on in the installed position of the ladder body 1.

[0035] The tread element 21 is integrally and rigidly connected to a step element 20, which adjoins the tread surface 16 at a right angle on a side of the tread surface 16 opposite the pivot section 15. In the present embodiment, the pivot section 15 runs perpendicular to the tread surface 16. In the installed position, the tread surface 16 covers the second guardrail 17 and the barrier 19.

[0036] To climb over the Super-Rail guardrail, the person steps onto the platform 16 from above. With the exception of platform 16, the second body section 3 and the first body section 2 are open, with opposing, identically shaped struts connected by transverse connecting struts. The connecting struts also serve as steps 22 for ascending and descending the ladder body 1. As shown from Figure 2As can be seen, the first body part 2 has a step element 23 that extends from the U-shaped profile 6 to the free end 4. As can be seen from Figure 1 As can be seen, the second body part 3 has the step element 20, which extends from the tread surface element 21 to the free end 5 of the second body part 3. The step element 23 of the first body part 2 is arranged parallel to the step element 20 of the second body part 3 in the assembly position.

[0037] To ensure that the step elements 20, 23 of the first body part 2 and the second body part 3 run vertically or parallel to each other in the assembled position, both the step element 23 of the first body part 2 and the step element 20 of the second body part 3 have a number of stop sections, each with a stop surface 24, 25. The stop surface 24 of the first body part 2 abuts the first upright side 12 of the first guardrail 7 or the first upright side of the second guardrail 17. The stop surface 25 of the second body part 3 abuts one side of the guardrail 19. The connecting sections are arranged with such a projection that the step elements 20 and 23 run vertically in the assembled position.

[0038] The first body part 2 has, as an extension of the first leg 9 and the second leg 10 of the U-shaped profile 6, a first handrail 26 and a second handrail 27, which run parallel to each other, each in extension to the first leg 9 and the second leg 10 of the U-shaped profile 6. The first handrail 26 and the second handrail 27 are each U-shaped.

[0039] The ladder body 1 is made of a metal material, in particular an aluminum material. The ladder body 1 is adapted to the shape of the guardrail system. If, for example, only a single guardrail 7 is provided, the angled section 14 can be omitted, so that the second body part 3 is essentially identical to the first body part 2, forming a step element.

[0040] According to an embodiment of the invention not shown, the apex 8 of the U-shaped profile 6 is designed to be longitudinally displaceable. In this way, the length l S of the apex 8 can be adapted to the width b of the guardrail 7.

[0041] According to a further embodiment of the invention, a ladder body 1' is formed in two parts, wherein, for assembly, a first body part 2' is first placed or hooked onto a guardrail arrangement. A second body part 3' is then detachably attached to the first body part 2' in a second assembly step.

[0042] The first body section 2' has the U-shaped profile 6, the apex length of which is adapted to the width of the upper guardrail 7. After the first body section 2' is placed or hooked into position, it is securely positioned on the upper guardrail 7.

[0043] The second body part 3' is then connected to the first body part 2' by, for example, a clamping or snap-fit ​​connection. Alternatively, the second body part 3' can also be connected to the first body part 2' by a screw connection.

[0044] Identical components or component functions of the exemplary embodiments are provided with the same reference numerals.

[0045] In the present embodiment, the first body part 2' is connected to the second body part 3' via a hook connection, wherein the second body part 3' has a hook element 30 which is hooked onto a retaining pin 31 of the first body part 2'.

[0046] The first body part 2' essentially corresponds to the shape of the first body part 2 according to the first embodiment. The second body part 3' essentially corresponds to the second body part 3 of the first embodiment. The main difference is that the first body part 2' and the second body part 3' are not connected to each other via a pivot bearing, but rather via a hook connection. Furthermore, the second body part 3' has several adjustment elements 32, 33, by means of which width compensation of the ladder body 1' is ensured for different guardrail arrangements, i.e., guardrails of different types. The adjustment elements 32, 33 enable the distance of the step element 20 of the second body part 3' to the guardrails 7, 17 or guide rails 19 to be variably adjustable.Consequently, the distance between the step element 23 of the first body part 2' and the step element 20 of the second body part 3' can also be adjusted differently. This ensures that, in the assembled position, the step elements 20 of the second body part 3' always run vertically.

[0047] As from Figure 5 As can be seen, a first adjustment element 32 is arranged in an upper area of ​​the second body part 3', namely at a free end of the tread element 21. A second adjustment element 33 is arranged in a lower area of ​​the second body part 3', specifically in the area of ​​the step element 20.

[0048] The first adjustment element 32 and the second adjustment element 33 are each designed as adjustment brackets, each pivotably arranged about a pivot axis 29 relative to the tread element 21 or step element 20, respectively. The first adjustment element 32 and the second adjustment element 33 each have fastening means so that, in a first adjustment position (locking position), they are preferably fixedly connected to the tread element 21 or step element 20, respectively, and each form a stop surface 44 for the guardrail 7 or barrier 19, respectively. The first adjustment element 32 and the second adjustment element 33 each have fastening means so that, in a second adjustment position (non-locking position), they are preferably movable or loosely connected to the tread element 21 or step element 20, respectively, and do not form a stop surface 44 for the guardrail 7 or barrier 19, respectively.

[0049] In the first adjustment position of the first adjustment element 32 and the second adjustment element 33, the distance between the opposing step elements 20, 23 of the first body part 2' and the second body part 3' is greater than in the second adjustment position of the same, in which the first adjustment element 32 or the second adjustment element 33 is pivoted away, releasing the stop surface 24 of the tread element 21 or the stop surface 25 of the step element 20, respectively, whereby a larger distance is formed between the step element 23 of the first body part 2' and the step element 20 of the second body part 3'.

[0050] In Figure 6The mounting position of the ladder body 1' in a guardrail arrangement of a second type, designated as the Super-Rail guardrail ECO, is shown. The first adjustment element 32 of the second body part 3' is in the second adjustment position (non-locking position), in which the first adjustment element 32 does not act as a stop surface, but instead a stop surface 24 of the step element 21 abuts the upper guardrail 7. The second adjustment element 33 is also in the second adjustment position (non-locking position), in which it does not form the stop surface, but instead a stop surface 25 of the step element 20 abuts the guardrail 19. A distance a2 is formed between the opposing step elements 20 of the first body part 2' and the second body part 3', which is smaller than the distance in the first adjustment position of the first adjustment element 32 and / or the second adjustment element 33.

[0051] In contrast, the second adjusting element 33 is, when mounted on another guardrail arrangement of a different type, according to Figure 7 In this case, it is a Super-Rail ECO H5 guardrail in the first adjustment position, in which the second adjustment element 33 forms the stop surface 44. The guardrail arrangement according to Figure 7 features a guardrail 17 which has a smaller horizontal width than the guardrail 17 according to Figure 6 Therefore, guardrail 19 is in accordance with Figure 7 less projecting from the post 18 than in the guardrail arrangement according to Figure 6. This ensures a distance b1 between the step element 20 of the first body part 2' and the guardrail post 18 – as in the embodiment according to Figure 6To ensure compliance, the second adjusting element 33 is moved into the first adjusting position (locking position), in which the stop surface 44 of the second adjusting element 33 rests against the guardrail 19. The reduction in the distance between the step element 20 and the guardrail post 18 when changing the design of the guardrail arrangement Fig. 6 to Fig. 7 This is thus compensated for.

[0052] A distance a1 between the stop surface 44 of the second adjusting element 33 and the opposite step element 23 of the first body part 2' is therefore smaller than the distance a2 between the stop surface 24 of the step element 20 of the second body part 3' and the opposite step element 23 of the first body part 2'.

[0053] In order to ensure that the step element 20 can still be aligned in a vertical direction, the second adjustment element 32 in the intended first adjustment position allows for width compensation with respect to the horizontal relative position of the guardrail 19 to the second body part 3', so that the step element 20 can be arranged vertically.

[0054] In Figure 8 Is the guardrail arrangement in accordance with the Figures 1 to 3 The illustration shows the type designation Super-Rail guardrail. Both the first adjustment element 32 and the second adjustment element 33 are in the first adjustment position (locking position), in which they themselves form the stop surface 44 on the upper guardrail 7 or on the guide rail 19. This results in a greater distance b2 between the step element 20 of the first body part 2' and the guardrail post 18 than in the embodiment according to Fig. 6 and Fig.7 .

[0055] Depending on the type of guardrail arrangement, the first adjusting element 32 and the second adjusting element 33 are moved into either the first or the second adjusting position before assembly. To move the adjusting elements 32 and 33 into the first adjusting position, an engagement hook 34 of the first adjusting element 32 engages the retaining pin 31 of the first body part 2', and an engagement hook 34 of the second adjusting element 33 engages the retaining pin 35 of the step element 20 of the second body part 3'. In the first adjusting position, the engagement hook 34 is thus in a locking position. In the second adjusting position, the engagement hook 34 is in a non-locking position with respect to the retaining pin 31 or 35, and is not engaged.

[0056] The adjusting elements 32, 33 each have an elongated hole in which a bolt of the rotary axis 29 is linearly displaceable, so that the engagement hook 34 can be moved into the locking position.

[0057] According to an alternative embodiment of the invention (not shown), more than two adjustment elements can also be provided. Optionally, the adjustment element can also be fixed in several positions, so that the number of guardrail arrangements to be compensated for in width can be increased.

[0058] To attach the second body part 3' to the first body part 2', a hook element 30 of the second body part 3' engages a retaining pin 31 of the first body part 2'. The second body part 3' is supported against the guardrail assembly by its contact surfaces. For this purpose, the hook element 30 is located at an upper end of the second body part 3'. The retaining pin 31 is located on the upper part of the U-shaped profile 6 of the first body part 2'.

[0059] According to an embodiment of the invention (not shown), instead of the pivotably mounted first adjustment element 32 and / or the pivotably mounted second adjustment element 33, a linearly movable adjustment element can be provided in each case, which is mounted so as to be movable back and forth between a locking position and a non-locking position. Fastening means serve to fix the first adjustment element and / or the second adjustment element in the locking position.
