[0003] Swing door for scaffolding Description

[0004] The present invention relates to a swing door for a scaffold, such as a construction scaffold comprising a plurality of scaffold platforms.

[0005] On scaffolding structures that provide multiple platforms stacked on top of each other, these platforms can be accessed, for example, via a ladder running along one of the scaffold's outer edges. To allow access to the platforms, which are generally secured by guardrails on their outer edges, swing gates are integrated into these guardrails.

[0006] Several requirements apply to such swing doors. Firstly, they must only open inwards, away from the ladder, and must be secured against opening outwards, towards the ladder. The swing doors must be designed so that they cannot open unintentionally, even under strong winds. Finally, depending on where a ladder is located on the scaffold or platform, these swing doors must be hinged on either the right or left side.

[0007] From DE 20 2015 000 707 U1, a swing door for scaffolding is known, in which a door leaf can be pivotally coupled to perforated discs provided on a vertical post of the scaffolding in two pivot coupling areas arranged one above the other in a vertical direction. The pivot axes formed at the two pivot coupling areas are offset from each other, so that when pivoting from a closed position to an open position, the center of gravity of the door leaf is raised, and thus the door leaf is biased towards its closed position by the force of gravity. The swing door can be converted between a left-hinged and a right-hinged state by changing the installation position of the lower pivot coupling area in the vertical direction. 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0008] - 2 -

[0009] The object of the present invention is to provide a pivot door for a scaffold which, with a structurally simple and operationally reliable design, allows for easy conversion between a left-hinged and a right-hinged state.

[0010] According to the present invention, this problem is solved by a pivot door for a scaffold, comprising a door leaf, a mounting assembly pivotably connected to the door leaf about a door pivot axis for fixing the pivot door to at least one scaffold element of a scaffold, and a pre-tensioning / pivot stop assembly, wherein the pre-tensioning / pivot stop assembly comprises: a door leaf coupling element coupled to the door leaf, a mounting assembly coupling element coupled to the mounting assembly and pivotably connected to the door leaf coupling element about an assembly pivot axis, a pivot stop on the door leaf coupling element and a counter-pivot stop on the mounting assembly coupling element, and a pivot pre-tensioning arrangement for pre-tensioning the door leaf coupling element relative to the mounting assembly coupling element into a pivot stop position.wherein in the pivot stop position the pivot stop is in contact with the counter pivot stop, and wherein the door leaf coupling element is pivotable from the pivot stop position relative to the fastening assembly coupling element about the assembly pivot axis against the preload effect of the pivot preload arrangement, wherein the door leaf coupling element is rotatably coupled to the door leaf about a first axis of rotation between a first locking position of the door leaf coupling element and a second locking position of the door leaf coupling element, and wherein the fastening assembly coupling element is rotatably coupled to the fastening assembly about a second axis of rotation between a first locking position of the fastening assembly coupling element and a second locking position of the fastening assembly coupling element, and wherein the preload 68678P DE Wilhelm Layher Verwaltungs-GmbH,

[0011] - 3 - clamping / swivel stop assembly with the door leaf coupling element positioned in each of its locking positions and the fastening assembly coupling element positioned in each of its locking positions, on the door leaf against rotation about the first axis of rotation and / or on the fastening assembly against rotation about the second axis of rotation.

[0012] In the swing door constructed according to the invention, the pre-tensioning / swing stop assembly performs both the function of pre-tensioning the door leaf towards a closed position and the function of providing a movement stop to prevent the swing door from opening outwards on scaffolding, towards a ladder. Since the pre-tensioning / swing stop assembly is rotatable between the two locking positions, both the direction of pre-tensioning and the direction of stop action can be reversed simply by adjusting the pre-tensioning / swing stop assembly between these locking positions, thereby converting the swing door between a left-hinged and a right-hinged state.

[0013] For this purpose, the door leaf coupling element can be rotated 180° around its first axis of rotation to move between its first and second locking positions, and the fastening assembly coupling element can be rotated 180° around its second axis of rotation to move between its first and second locking positions. This means that, with the preload / swivel stop assembly being freely rotatable relative to the door leaf coupling element and the fastening assembly coupling element, two rotational positions with an angular distance of 180° to each other correspond to the locking positions.

[0014] To allow the two coupling elements to rotate relative to each other, and in particular to avoid the occurrence of constraints when the swing door pivots, it is proposed that in the pivot stop position the first axis of rotation essentially corresponds to the second axis of rotation, and / or that the first axis of rotation and / or the second axis of rotation form the assembly pivot axis 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0015] - 4 - intersects or / and is essentially parallel to it, or / and that the assembly group pivot axis essentially corresponds to the door pivot axis.

[0016] To lock the preload / swivel stop assembly in each of the locking positions, at least one locking element can be provided on the door leaf and / or the fastening assembly, and at least one counter-locking element that can be brought into locking interaction with at least one locking element can be provided on the preload / swivel stop assembly.

[0017] For a structurally simple yet reliable locking design, it is proposed that: a locking element is provided on the door leaf transversely to the first axis of rotation, preferably in the direction of the assembly's pivot axis, and / or on the mounting assembly transversely to the second axis of rotation, preferably in the direction of the assembly's pivot axis; and two counter-locking elements are provided on the pre-tensioning / swivel assembly transversely to the first axis of rotation in opposite directions, preferably in the direction of the assembly's pivot axis, and / or transversely to the second axis of rotation in opposite directions, preferably in the direction of the assembly's pivot axis, wherein in each locking position one of the counter-locking elements is aligned with the locking element to provide a locking interaction.or that two locking elements are provided on the door leaf transversely to the first axis of rotation in opposite directions, preferably in the direction of the assembly pivot axis, and / or on the fastening assembly transversely to the second axis of rotation in opposite directions, preferably in the direction of the assembly pivot axis, and a counter-locking element is provided on the pre-tensioning / swivel assembly transversely to the first axis of rotation and / or transversely to the second axis of rotation, preferably in the direction of the assembly pivot axis, wherein in each locking position the counter-locking element is equipped with a- 68678P DE Wilhelm Layher Verwaltungs-GmbH,

[0018] - 5 - nem of the locking organs is aligned to provide a locking interaction.

[0019] For example, each locking device may include a through-hole for receiving a locking bolt, and each counter-locking device may include a locking opening for locking engagement with a locking bolt passing through a through-hole.

[0020] To prevent unintentional release of the locking interaction, at least one, preferably each, locking bolt can comprise an externally threaded bolt, and at least one, preferably each, locking opening can comprise an internally threaded opening.

[0021] To maintain large preload forces for preloading the swing door in the direction of its closing position, the swing preload assembly can include at least one preload spring, preferably a torsion spring.

[0022] For a stable yet cost-effective construction, at least one, preferably each, coupling element of door leaf coupling element and fastening assembly coupling element can be designed as a sheet metal part.

[0023] For the pivot coupling of the two coupling elements, it is proposed that each coupling element of the door leaf coupling element and the fastening assembly coupling element is essentially U-shaped with two U-legs and a connecting web connecting the two U-legs, that the coupling elements are pivotably connected to each other about the assembly pivot axis by a pivot bolt passing through each U-leg, and that the pivot stop comprises the connecting web of the door leaf coupling element and the counter-pivot stop comprises a stop projection extending from the connecting web and / or at least one U-leg of the fastening assembly coupling element, and / or the pivot stop comprises a stop projection extending from the connecting web and / or at least one leg of the door leaf coupling element. 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0024] - 6 - and the counter-swivel stop includes the connecting web of the fastening assembly coupling element.

[0025] A defined positioning of one or more preload springs designed as torsion springs can be achieved by having a coil area of ​​the at least one torsion spring surround the pivot bolt and by having at least one leg section of the at least one torsion spring supported with respect to the door leaf coupling element and at least one leg section of the at least one torsion spring supported with respect to the fastening assembly coupling element.

[0026] For the rotary coupling of the door leaf coupling element with the door leaf, a first pivot bolt, preferably connected to the door leaf coupling element in a rotationally fixed manner, can be provided, and for the rotary coupling of the fastening assembly coupling element with the fastening assembly, a second pivot bolt, preferably connected to the fastening assembly coupling element in a rotationally fixed manner, can be provided.

[0027] In order to ensure increased safety against falling objects or people in the lower area of ​​such a swing door, a toe board assembly extending essentially transversely to the door leaf's pivot axis can be provided on the door leaf in a lower end area of ​​the door leaf in the direction of the door leaf's pivot axis.

[0028] To adapt to different opening widths, the toe board assembly can essentially be telescopically extended transversely to the door leaf pivot axis.

[0029] A further measure to prevent the door leaf from opening outwards on a scaffold can be provided by installing a door leaf pivot stop in a lateral end area of ​​the door leaf, perpendicular to the pivot axis and away from the mounting assembly, whereby when the pre- 68678P DE Wilhelm Layher Verwaltungs-GmbH is positioned in or near the pivot stop position

[0030] - 7 - The clamping / swivel stop assembly of the door leaf swivel stop is in stop interaction with a scaffolding element or can be brought into contact with it.

[0031] In order to achieve adaptation to different stop positions of the door leaf, it is proposed that the door leaf swing stop can be mounted on the door leaf in one of two mounting positions to adapt to each locking position of the door leaf coupling element and the fastening assembly coupling element.

[0032] A reliable, yet easy-to-install and dismantle connection of the swing door to a scaffold can be achieved by the fastening assembly having two wedge heads arranged at a distance from each other in the direction of the door leaf's pivot axis for the detachable fastening of the fastening assembly to perforated discs provided on at least one scaffold element.

[0033] The invention further relates to a scaffold comprising a plurality of scaffold elements extending essentially in one vertical direction and at least one pivot door with a structure according to the invention, attached to at least one of the scaffold elements extending in the vertical direction.

[0034] The present invention is described in detail below with reference to the accompanying figures. These show:

[0044] Fig. 9 shows the preload / swivel stop assembly of the open swing door shown in Fig. 8.

[0045] Figure 1 shows a side view of a scaffold, generally designated 10 and designed, for example, as a construction scaffold. The scaffold 10 comprises a plurality of vertical uprights 12 extending essentially in a vertical direction H, each with a plurality of perforated discs 13 attached to them. The vertical uprights 12 are connected to each other by horizontal beams 14. Scaffold platforms 16 can be formed on the scaffold 10 at various height positions in the vertical direction H. For this purpose, floor elements 18 are suspended from horizontal beams 14 running between the vertical uprights 12, on which persons on the scaffold 10 can stand or move. To secure such scaffold platforms 16 against the falling of persons or objects, guardrail structures, generally designated 20, are provided, which can comprise a plurality of further horizontal beams 22 and toe boards 24 near each of the floor elements 18.

[0046] To access such scaffolding platforms 16, a ladder 26 can run along the outside of the scaffolding 10. To access a 68678P DE Wilhelm Layher Verwaltungs-GmbH from the ladder 26

[0047] - 9 - To obtain such a scaffold platform 16, a swing door 28 is integrated into the railing structure 20 in a side area of ​​the scaffold 10 or the scaffold platform 16 that is close to the positioning of the ladder 26. The swing door 28 is designed so that it can only swing inwards towards the inside of the scaffold platform 16, i.e. in the direction away from the ladder 26 and, in the illustration of Fig. 1, to the rear.

[0048] The construction and function of such a swing door 28 are described in detail below with reference to the accompanying Figs. 2 to 9.

[0049] The swing door 28, also shown in Fig. 2, comprises a door leaf 30 with, for example, two vertical bars 32, 34 extending in the vertical direction H and two horizontal bars 36, 38 firmly connected to the vertical bars 32, 34, for example, in an upper and a middle region, for example, by welding, screwing or the like. In a lower region of the vertical bars 32, 34 in the vertical direction H, a toe board assembly 40, which will be described below, is connected to the vertical bars 32, 34.

[0050] For connection to the vertical uprights 12 of the scaffold 10, which extend essentially in the vertical direction H, the door leaf 28 comprises a fastening assembly 42. The fastening assembly 42 comprises a plate-like or rod-like component element 44 that extends essentially in the vertical direction H. Two wedge heads 46, 48 are attached to this component at a distance from each other, for example by welding, the distance between which essentially corresponds to the distance between two perforated discs 13 of the vertical uprights 12. The wedge heads 46, 48 thus allow the fastening assembly 42, and with it the door leaf 30, to be stably attached to the scaffold 10 or a vertical upright 12 thereof in a defined position and equally easily decoupled from it.

[0051] The assembly element 44 is pivotably connected to the door leaf 30 or the vertical rod 32 thereof about a door pivot axis T in two areas spaced apart from each other in the vertical direction H, for example, near its two end regions. For this purpose, assembly element 44 can be 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0052] - 10 - and on the vertical rod 32 respective pivot tabs are provided which are pivotably connected to each other by bolt-like pivot elements.

[0053] In the vertical direction H between the pivot tabs provided at the end regions of the assembly element 44 or the associated regions of the vertical rod 32, a pre-tensioning / swivel stop assembly 50 is provided. This serves, on the one hand, to pre-tension the door leaf 30 in the direction of a closed position, and on the other hand, provides a stop function which ensures that the door leaf 30, pre-tensioned in the direction of its closed position, cannot move beyond this closed position.

[0054] The preload / swivel stop assembly 50, shown in more detail in Figures 3, 7, and 9, comprises a door leaf coupling element 52 coupled to the door leaf 30, in particular to the vertical rod 32 thereof, and a fastening assembly coupling element 54 coupled to the fastening assembly 42 or the assembly element 44 thereof. The door leaf coupling element 52 and the fastening assembly coupling element 54 are, for example, designed as sheet metal parts, each with a substantially U-shaped form. The door leaf coupling element 52 has two U-shaped legs 56, 58 and a connecting web 60 connecting the U-shaped legs 56, 58. Similarly, the assembly coupling element 54 has two U-shaped legs 62, 64 and a connecting web 66 connecting the U-shaped legs 62, 64.The slightly larger door leaf coupling element 52 encompasses the assembly coupling element 54 with its two U-shaped legs 56, 58, such that the U-shaped legs 56, 58 of the door leaf coupling element 52 are positioned outside the U-shaped legs 62, 64 of the assembly coupling element 54 and overlap them. A pivot bolt 68, which extends through all U-shaped legs 56, 58, 62, 64 and / or openings provided therein, couples the door leaf coupling element 52 and the assembly coupling element 54 to each other for pivoting about an assembly pivot axis B.

[0055] A pivot stop 70 is provided on the door leaf coupling element 52 by means of the connecting web 60 thereof. In association with the pivot stop 70 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0056] - 11 - of the door leaf coupling element 52, a counter-swivel stop 72 is provided on the assembly coupling element 54 by a stop projection 74 extending from the connecting web 66 of the same. In a pivot stop position of the preload / swivel stop assembly 50, the door leaf coupling element 52 with its pivot stop 70 is in contact with the counter-swivel stop 72 formed on the assembly coupling element 54. In an open position of the door leaf 30, which will be explained below, the pivot stop 70 formed on the door leaf coupling element 52 is, as shown in Fig. 9, away from the counter-swivel stop 72 of the assembly coupling element 54.For example, it can be provided that in a fully open position of the door leaf 30, the connecting web 60 of the door leaf coupling element 52 rests against the connecting web 66 of the assembly coupling element 54, and thus a further movement stop limiting the pivoting path of the door leaf 30 when opening it is provided by the pre-tension / pivot stop assembly 50.

[0057] It should be noted that in an alternative embodiment for providing the pivot stop 70, a stop projection may be provided on the connecting web 60 of the door leaf coupling element 62, in which case the counter-pivot stop 72 may be provided by the connecting web 66 of the assembly coupling element 54. Furthermore, such a stop projection may be provided on each of the connecting webs 60, 66, which may then interact with the connecting web of the respective other coupling element or with a stop projection provided thereon to provide the pivot stop. Alternatively or additionally, such a stop projection may also be provided on at least one of the U-shaped legs of each coupling element.

[0058] To pre-tension the two coupling elements 52, 54 into the pivot stop position associated with the closed position of the door leaf 30 and visible in Fig. 7, a pivot pre-tensioning arrangement 76 is provided. In the illustrated example, this comprises a torsion spring 78 with two coil sections 80, 82 of a coil, spaced apart from each other in the direction of the assembly's pivot axis. 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0059] - 12 - Reichs 84 of the same. At the end regions of the coil sections 80, 82, which are spaced apart from each other in the direction of the assembly pivot axis B, respective leg sections 86, 88 extend radially outwards with respect to the assembly pivot axis B and are supported circumferentially on the connecting web 66 of the assembly coupling element 54. A leg section 90 of the leg spring 78, located between or connecting the two coil sections 80, 82, extends radially outwards with respect to the assembly pivot axis B and is supported circumferentially on the connecting web 60 of the door leaf coupling element 52. Due to the preload effect of the leg spring 80, the two coupling elements 52, 54 are preloaded into the pivot stop position shown in Fig. 7 and held in this position.To pivot the two coupling elements 52, 54 out of this pivot stop position, a closing force provided by the pre-tensioned installation of the leg spring 78 must first be overcome.

[0060] The preload / swivel stop assembly 50 is installed between the fastening assembly 42 and the door leaf 30 such that it can be arranged and locked in two locking positions relative to the fastening assembly 42 and the door leaf 30, respectively, as described below. As can be seen in Fig. 3, a pivot bolt 92 is provided on the door leaf coupling element 52, projecting from the connecting web 60 thereof. This pivot bolt is rotatable about a first axis of rotation Di in corresponding openings 94 of the vertical rod 32, which is preferably designed as a hollow component. Alternatively, the pivot bolt 92 could be fixed to the vertical rod 32 and rotatable about the first axis of rotation Di in an opening formed in the connecting web 60. To provide a single assembly, the first pivot bolt 92 is preferably fixed to the door leaf coupling element 52.

[0061] Likewise, a second pivot bolt 96 is preferably fixed to the assembly coupling element 54 or the connecting web 66 thereof, projecting outwards, and is rotatably received in openings 98 in the assembly element 44, which is preferably also designed as a hollow component, about a second axis of rotation D2. When in the pivot stop position relative to each other, 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0062] - 13 - The two pivot axes Di and D2 of the coupling elements 52, 54 correspond to each other. Furthermore, the two pivot axes Di and D2 are preferably positioned such that, regardless of the pivot position of the two coupling elements 52, 54 relative to each other, they intersect the assembly pivot axis B and are substantially parallel to it. Furthermore, the preload / pivot stop assembly 50 is preferably arranged between the assembly element 44 and the door leaf 30 such that the assembly pivot axis B corresponds to the door pivot axis T.

[0063] To lock the preload / swivel stop assembly in the two locking positions, a locking element 102 comprising through-openings 104 in the vertical rod 32 is provided on the door leaf 30. The through-openings 104 are penetrated by a locking bolt 100 designed as an externally threaded bolt, for example as a screw. The through-openings 104 and the locking bolt 100 penetrating them are arranged offset on the door leaf 30 and the vertical rod 32, respectively, in the direction of the assembly's swivel axis B with respect to the first axis of rotation Di.

[0064] On the door leaf coupling element 52, two nuts 110, 112 are provided in opposite directions to each other along the assembly pivot axis B with respect to the first axis of rotation Di. Each nut provides a counter-locking element 106, 108 and has a locking opening 109 designed as an internal thread opening. These nuts can, for example, be fixed to the connecting web 60 of the door leaf coupling element 52 by welding.

[0065] In the locking position shown in Fig. 3, the locking element 102 is screwed into the counter-locking element 106 or the nut 110, so that the door leaf coupling element 52 is locked against rotation about the first axis of rotation Di. Thus, when the axes of rotation Di, D2 are aligned with each other, i.e., when the coupling elements 52, 54 are positioned in the pivot stop position, the assembly coupling element 54 is also locked against rotation relative to the assembly element 44 about the second axis of rotation D2. When the axes of rotation Di, D2 are not aligned with each other, i.e., when the coupling elements are not positioned in the pivot stop position, 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0066] - 14 -

[0067] 52, 54, due to the angled positioning of the axes of rotation Di, D2 relative to each other, a rotation of the two pivot bolts 92, 94 about the respective associated axis of rotation Di , D2 is fundamentally not possible.

[0068] To lock the assembly in the further locking position, which is offset by 180° relative to the locking position shown in Fig. 3, the locking bolt 100 can be unscrewed from the locking opening 109, thus releasing the threaded engagement with the nut 110. Subsequently, with the axes of rotation Di, D2 aligned relative to each other, the preload / swivel stop assembly 50 can be rotated by 180° so that the nut 112 of the counter-locking element 108 is aligned with the through-openings 94 of the locking element 102 to establish a locking interaction, and the locking bolt 100 can be screwed into the nut 112 of the counter-locking element 108. In this state, the preload / swivel stop assembly 50 is also held securely against rotation about the axes of rotation Di, D2.

[0069] It should be noted that the locking of the preload / swivel stop assembly 50 could also be achieved, for example, by a locking element 102, which is provided on the assembly element 44 in a manner corresponding to the illustration in Fig. 3. In this case, the counter-locking elements 106, 108 are then provided on the assembly coupling element 54. In a further alternative embodiment, two locking elements 102, each with through-openings 104 for receiving a locking bolt 100, could be provided on the door leaf 30 or on the assembly element 44, offset from each other in the direction of the assembly swivel axis B on both sides of the first axis of rotation Di, while only one counter-locking element, for example the counter-locking element 106, is provided on the door leaf coupling element 52.Depending on the selected locking position, the locking bolt 100 can then be guided through one of the pairs of through-openings 104, with which the counter-locking element 106 provided on the door leaf coupling element 52 is aligned. Such an alternative design could also be achieved by a corresponding locking interaction between the assembly coupling element 54 and the assembly element 44. For a reinforced locking interaction, see 68678P DE Wilhelm Layher Verwaltungs-GmbH.

[0070] - 15 - kung such locking measures can be implemented both in connection with the door leaf 30 and in connection with the assembly element 44.

[0071] By rotating the preload / swing stop assembly 50 between the two locking positions, it is possible to easily convert the swing door 28 or its door leaves 30 between a state corresponding to a left-hinged door and a state corresponding to a right-hinged door. This is described below with reference to Figures 4 to 9.

[0072] Figures 4, 6, and 7-9 show the installation of the swing door 28 such that it corresponds to a left-hinged door. The door leaf 30 can only be pivoted inwards, i.e., away from the ladder 26, in the direction of arrow L in Figure 4, from the closed position shown in Figure 6 to the open position shown in Figure 8. In the closed position of Figure 6, as illustrated in Figure 7, the pivot stop 70 of the door leaf coupling element 52 is in contact with the counter-pivot stop 72 of the assembly coupling element 54, so that the door leaf 30 cannot move outwards beyond the pivot stop position in the opposite direction to the pivot direction L, starting from the closed position shown in Figure 6.

[0073] When the door leaf 30 pivots into the open position, the pivot stop 70 moves away from the counter-pivot stop 72, so that when the door leaf 30 is fully open, the preload / pivot stop assembly 50 is in the state shown in Fig. 9. When opening the door leaf 30, the closing force provided by the torsion spring 78 must first be overcome, and the door leaf 30 must be pivoted against an increasing force from the torsion spring 78 acting in the direction of arrow L.

[0074] To modify the swing door 28 to provide a structure corresponding to a right-hinged door, which could then be positioned on the left side of the scaffold platform 16 as shown in Fig. 1, see 68678P DE Wilhelm Layher Verwaltungs-GmbH

[0075] - 16 -

[0076] In the pivot stop position with respect to the mutually positioned coupling elements 52, 54, and thus in a relative positioning of the door leaf 30 with respect to the fastening assembly 42 corresponding to the closed position of the door leaf 30, the pre-tension / pivot stop assembly 50 is rotated by 180° about the two axes of rotation Di, D2 corresponding to each other in this state and locked against further rotation in the manner described above. This rotation by 180° reverses both the direction of action of the torsion spring 78 and the direction of action of the pivot stop 70 cooperating with the counter-pivot stop 72, so that with the pivot door 28 rotated by 180° about a vertically extending axis with respect to the installation situation of Fig. 1 and the fastening assembly 42 fixed to the vertical posts 12 shown on the left in Fig. 1, the door leaf 30 is then in one of the representations of Fig.5 in the corresponding manner in the direction of an arrow R inwards into the scaffold platform 16 and away from a ladder attached to the outside of the scaffold 10.

[0077] A comparison of Figs. 4 and 5 shows that, regardless of whether the swing door 28 is designed as a left-hinged door or as a right-hinged door, the swing stop 70 and the counter-swing stop 72 are each arranged on the side of the pre-tension / swing stop assembly 50 that faces outwards, i.e. in the direction away from the scaffold platform 16 or in the direction towards a ladder 26 provided on the outside of the scaffold 10.

[0078] To further secure the swing door 28 or its leaf 30 against pivoting beyond the pivot stop position provided by the pre-tension / swing stop assembly 50, a door leaf swing stop 120 is provided by a rod-like stop element 118. The stop element 118 can, for example, be fixed by screwing it to the horizontal rod 38 positioned in the middle area of ​​the door leaf 30 and extend away from the fastening assembly 42 beyond the door leaf 30 or its vertical rod 34.
