Description

The present invention relates to a closure device for a Parkouraufbau and a Parcouraufbau.

Parkour is a sport in which the athlete makes a fast and efficient journey to a destination, overcoming natural or nature-inspired obstacles. An obstacle can be a wall that needs to be overcome. By pushing against the wall, a forward movement can be diverted into a vertical movement. An important element of Parkoursports are jumps and the associated landing techniques (landing on the feet, rolling landing, landing in a hanging position). To practice the techniques used in the parkour sport or to provide comparable conditions for competition, a parkour structure according to the present invention may be used.

The equipment known from the Tumsport such as Bock, box (see DE 31 45 590 A1 . GB 538,563 and FR 2,185,932 ), Horizontal bars, bars and balance beams are only conditionally suitable for providing such a parkour structure, since these are not designed for the special techniques of parkour sport and they can also lack the required stability. Furthermore, it lacks a suitable interface for the most flexible design of Parkouraufbauten based on a few basic elements.

It is therefore an object of the present invention to improve this.

The object underlying the invention is achieved by a closure device for firmly connecting an obstacle element of a Parkouraufbaus with a connecting element of a Parkouraufbaus, comprising a plug element and a receiving element, wherein the plug element is inserted into the receiving element along an insertion direction, wherein the plug element comprises a base body which is at least partially insertable through a receiving opening of the receiving element, and that the plug element comprises a blocking device, wherein the blocking device in a blocking position of the plug element prevents displacement of the plug element in the insertion direction relative to the receiving element, wherein a release position of the plug element a displacement of the plug element in the insertion direction relative to the receiving element is made possible.

It is inventively provided a securing device by means of which the plug element is secured against the receiving element against unintentional loosening. It is prevented by the additional securing device that an unintentional displacement of the plug element from the blocking position takes place in the release position. The securing device can also serve for the transmission of forces, in particular of vertically upward forces on the obstacle element. An actuation of the securing device may preferably allow a displacement of the plug element relative to the receiving element, whereas a displacement of the plug element is prevented when not actuated. In this case, spring-loaded means may be provided, which act on the safety device by default in a non-actuated state.

By such a closure device, a secure and stable attachment of the connecting element or other accessories to the obstacle element can be provided. In particular, unintentional release of the closure device is made more difficult. In the blocking position, the plug element can preferably be arranged vertically lower than in the release position. Thereby, the blocking position can represent a stable state of the plug element, since the force of gravity can act on the connecting element in the blocking position.

Preferably, the blocking device comprises a first blocking surface and a second blocking surface, wherein the first blocking surface is substantially facing the second blocking surface, and wherein a contact surface of the plug element for abutment against the receiving element between the two blocking surfaces is arranged. This may result in that the contact surface of the plug element can come into the wall of a recess for force-transmitting system on a side surface of the obstacle element. The two blocking surfaces can then come into abutment with adjacent surfaces and in particular absorb parts of the side surface in a blocking position between them, whereby a movement of the plug element can be prevented transversely to the blocking surfaces.

Preferably, the blocking device has a blocking bar, which is aligned transversely to the base body. The base body and / or the locking bar can have a cylindrical basic shape, with square as well as round, in particular circular Can be based on surfaces of the cylindrical shape. In this case, transverse refers to a cylinder axis, namely in particular to an axis along the largest extent of the blocking bolt or the basic body.

Preferably, a receiving element is formed by two perpendicularly crossing slots in one of the side surfaces. One of the slots preferably extends in the vertical direction, while another of the slots extends in the horizontal direction. Due to the vertically extending slot, a main body of the plug element can be introduced into the receiving element both in the release position and in the blocking position. The horizontally extending slot can make it possible for a blocking element to be introduced into or out of the receiving element only in a release position. In a blocking position, a passage of a blocking element into the receiving element or out of the receiving element or out of the receiving element can be prevented.

Preferably, the securing device has a securing body which can be inserted into a receiving opening of the receiving element. In the inserted state may result that the fuse body prevents movement of the plug element relative to the receiving element. As a result, the plug-in element can be secured in the blocking position. Unintentional release of the plug element can thus be prevented by the fuse body. Preferably, the securing body is at least partially complementary to a slot of the receiving element. This means, in particular, that a portion of the securing body may be substantially inversely formed to a slot of the receiving element, namely such that the securing body may be held substantially form-fitting at least transversely to the insertion within the receiving opening.

Preferably, the securing body has a rigid locking surface and a movable locking surface. The securing surfaces can be provided for a positive retention of the securing body within the receiving element. For this purpose, the securing surfaces are preferably aligned facing each other. The movable locking surface can be movable between two positions, in particular be rotatable. In a first position, a blocking of the securing body in the receiving opening may be provided, whereas in a second position, a movement of the receiving body in the receiving opening may be possible. The securing surfaces can in particular be supported on a wall which forms the side surface of the obstacle element. The movable securing surface is preferably at one Attached to the end of the fuse body, which is arranged opposite to the direction of insertion of the rigid locking surface.

Preferably, the movable locking surface is rotatably mounted on the fuse body. The direction of rotation of the securing surface is preferably aligned coaxially with an insertion direction of the securing body into the receiving opening. Due to the coaxial alignment of the axis of rotation with respect to the insertion direction, it may be that an impact of the securing body in the insertion direction can have no effect on a possible rotational movement of the securing surface.
Preferably, the securing body can be inserted in the insertion direction in such a way that, at a certain point in time, the support surface can come into contact with the receiving element. In this case, in particular, the backup surface in a position in which it can not prevent a securing of the fuse body within the receiving opening. If the rigid locking surface then comes into contact with the receiving element, the movable locking surface can be moved so that it enters a securing position, whereby then a movement of the fuse body can be prevented within the receiving opening finally.

Preferably, the securing body is designed such that vertically upward-facing force components can be transmitted from the connecting element via the securing body to the obstacle element. This can contribute to the additional stabilization of the obstacle elements.

Preferably, an insertion direction of the fuse body and / or the plug element is aligned transversely to a displacement direction of the plug element from the blocking position in the release position. A loading of the plug element from the blocking position into the release position can be without influence on the securing body, in particular without influencing a possible loading of the securing body out of the receiving opening.

Preferably, the receiving element is formed directly by the side wall of an obstacle member, ie in particular that no further fittings or the like are provided on the side wall, which serve to reduce the surface pressure on the side wall. As a result, a simplified structure and a cost-effective design can be provided.

The object is further achieved by a Parkouraufbau comprising a first obstacle member, a second obstacle member, a connecting element, wherein the connecting element is connected to the first obstacle member and the second obstacle member, a closure device of the aforementioned kind for fixed connection of the connecting element with one of the obstacle elements.

In the context of the present invention, an obstacle element is understood to mean an element which is intended to be overcome by a sportsman during a passage of the parkour structure through a vertical movement. Under a vertical movement in particular climbs or jumps are to be understood. An obstacle element can be cuboid.
Under a connecting element is any device to understand with which two obstacle elements can be coupled, in particular such that forces can be transmitted to one of the two obstacle elements or between the two obstacle elements. By transferring forces from one obstacle element to the other obstacle element, the stability of one or both obstacle elements can be significantly increased. Furthermore, the connecting element can also be an element of the parkour, which must be overcome. Thus, the connecting element itself may be designed as a rod, in particular stretch rod or bar rod or be modeled on a balance beam.

Preferably, the first obstacle element has a parallelepipedal design with a length of at least 0.9 m, in particular 1.0 m, a width of at least 0.9 m, in particular 1.0 m and a height of at least 1.5 m, in particular at least 1.9 meters up. As a result of the dimensions of the obstacle element of this kind, improved stability of the first obstacle element can be achieved.

Preferably, the first obstacle element has at least two side surfaces, each of the side surfaces extending integrally over substantially the entire height of the obstacle element. In contrast to obstacle elements, which are formed by a plurality of successive sub-units, increased stability or stability of the obstacle element may result. A standing device on which the obstacle element can stand on a ground can be formed by lower edges of side surfaces. On separate feet can therefore be omitted if necessary.

The first obstacle element preferably ends laterally flush with all side surfaces. In particular, no foot devices are laterally beyond the side surfaces. As a result, a gymnastics mat can be created flush with the obstacle element to increase safety.

To increase the stability can be provided that the first obstacle element has a weight of at least 50 kg, preferably at least 75 kg, in particular in about 80 kg. The weight can be generated by the provision of separate ballast means. Nevertheless, the first obstacle element is preferably mobile with respect to a location, i. H. not firmly connected to a subsoil. For good transportability, the obstacle element can be provided with a chassis. The chassis can be engageable or disengageable. In an engaged state of the chassis, the obstacle member can stand firmly on a stand device, without the chassis favors rolling away; in a disengaged state of the chassis, the obstacle member favored by the chassis can be easily moved locally.

Preferably, side surfaces of the first obstacle element have a roughened surface, in particular a sanded surface. Conventional sports equipment, however, have a paint that can produce the smoothest possible surface, as this injury, especially skin abrasions should be avoided. The roughened surface may indeed show that skin abrasions can occur more frequently. However, this disadvantage is tolerated because the roughened surface can make it possible to overcome obstacle elements more effectively. In particular, by increasing the friction by the roughened surface and vertical or nearly vertical side surfaces can be overcome improved.

Preferably, the obstacle element is made of a waterproof material or equipped with a weatherproof layer. This allows the Parkouraufbau be applied outdoors. In particular, the Parkouraufbau can then be used to supplement in the wild, since the possibility of a sudden change in the weather now can not be an obstacle to such use.

Preferably, the first obstacle element is made of a composite fiber plate material. As a base material can be used in particular wood materials. Particularly suitable are multiplex panels, which consist of several layers of wood or plywood. The plates are pressed with glue or glue. The grains of adjacent plates are preferably oriented transversely to each other.

A wall thickness of side surfaces of the obstacle element is at least 4.0 cm, in particular at least 6.0 cm. By such a large wall thickness, it is possible that the side surfaces are very stable and can absorb directly as a supporting elements of the obstacle element, the transmitting forces of the connected fasteners. In this case, contact surfaces of the connecting elements can fall into direct contact with receiving surfaces on the side surfaces. Such receiving surfaces may be formed by the walls of holes or other openings in the side surfaces. When using multiplex panels, the minimum wall thickness can be reduced to at least 1.2 cm, in particular at least 1.5 cm, preferably at least 1.8 cm.

Preferably, side surfaces of the first obstacle element, in particular all side surfaces, each have at least one receiving element of a closure device. The receiving element of a closure device in this case represents the element of the closure device which is attached to the obstacle element. Another element of the closure device, in particular a plug-in element, can be attached to an attachment or to the connection element. By connecting the receiving element and the other part of the closure device, in particular a plug-in element, then a connecting element can be firmly connected to the obstacle element.

Preferably, side surfaces of the first obstacle element, in particular all side surfaces, each have two or more receiving elements, wherein the receiving elements are mounted at different heights. Alternatively or in combination thereto, side surfaces of the first obstacle element, in particular all side surfaces, each have two or more receiving elements, wherein receiving elements are mounted at the same height. By providing a plurality of, in particular differently arranged receiving elements, the possibility is created to attach fasteners or other accessories as flexible as possible to the obstacle elements.

Preferably, a side surface of the first obstacle element and a side surface of the second obstacle element mutually mirror-inverted receiving elements. This can be achieved that two parallel connecting elements between these obstacle elements can be attached. Here, for example, a barrenähnlicher structure can be provided. For the evaluation of the mirror-inverted arrangement, the distances of the receiving elements to a lateral edge of the obstacle element are irrelevant; Rather, the relative orientation of the receiving elements on both obstacle elements is relevant to each other or the arrangement of the receiving elements in the same amount relevant.

Preferably, the connecting element is represented by a turn bar, a stretching bar or a bar spar. The connecting elements can have a polygonal, round, oval or drop-shaped cross section. A round cross-section is advantageous since these forces can absorb or transmit well in all cross-sectional directions.

Preferably, a third obstacle element is provided, which is connected via a further connecting element with the first and / or the second obstacle element. It can also be provided further obstacle elements, which in turn can be connected via other connecting elements with the already existing obstacle elements. Furthermore, an inclined plane with the obstacle element can be fastened via the closure device.

Preferably, an inclined plane is fastened by means of a closure device to an obstacle element.

Preferably, an obstacle element on its lower edge on a horizontal support plate which protrudes at least section meadow from a vertical side surface. This horizontal support plate is in particular in contact with a floor on which this obstacle element stands. The support plate is then particularly suitable for improving the stability. By the support plate is meant substantially the area of an optionally larger element protruding from a side surface of the obstacle element. Such a support plate may also be arranged on another of the vertical side surfaces of the obstacle element. Several support plates can be integrally connected to each other. However, this horizontally protruding support plate entails an increased risk of uncontrolled contact with an athlete, as it can bend in unfavorable occurrence on an edge of this support plate with the foot. To prevent these kinking of the foot, a cover plate is preferably provided, which is aligned at an angle to the horizontal and the support plate in the region of a side wall, in particular the side wall, from which the support plate protrudes, substantially completely covered.

The angle of the cover plate relative to the horizontal is in particular 30 to 60 °, preferably about 45 °. The terms plate are to be interpreted broadly and do not necessarily require an exclusively plate-like shape. Rather, it is only necessary that the cover plate has a substantially flat surface on which the athlete can occur. The support plate does not have to be exclusively plate-shaped; Rather, the support plate should have at least one or more flat bearing surface for engagement with the ground. The support plate and the support plate are preferably at least indirectly fixedly connected to one of the side surface of the obstacle element.

Preferably, the obstacle element has a hexagonal base surface on whose edges side surfaces project vertically. When demarcating the base area, any support surfaces that are protruding vertically to the side surfaces may be disregarded. The base area results rather from the top view of the side surfaces. Due to the design of the obstacle element as a "hexagon", in particular with a uniform hexagonal base area, further expansion possibilities of the entire Parkouraufbaus arise; while in a substantially cuboid obstacle element only rectangular arrangements are possible allows the hexagonal basic shape significantly more variants of expansion, especially in narrow or narrow or crooked premises. Likewise, an obstacle element with an octagonal, in particular even octagonal base surface may be advantageous, to which the above statements are applied identically.

Preferably, the Parkouraufbau comprises a wall bar adapter. The wall-mounted wall adapter has as attachment means for fastening the wall-mounted wall adapter to a wall bar at least one receiving element, preferably two or more receiving elements of a closure device for connecting a connecting element. The rung wall adapter can essentially comprise a wall section, in particular a side wall, which largely corresponds to a side wall of an obstacle element. This wall section then comprises the receiving elements, in particular a plurality of receiving elements in different horizontal and vertical positions. By connecting the wall bar adapter to an existing wall bars an obstacle element can thus be simulated. The Parkouraufbau can therefore be made more cost-effective by utilizing the existing wall bars while sacrificing an obstacle element without having to forego essential expansion options. The means for attaching the wall bar adapter to the wall bars comprise in particular clamping means or holding means, in which the adapter hung on the wall bars and in particular can be secured against unintentional loosening. The invention consequently also relates to such a wall-mounted wall adapter, which can be connected to at least one other obstacle element to a Parkouraufbau according to claim 1.

Preferably, a sprout element is attached to an obstacle element. The sprout element has at least one rung. Furthermore, the rung element has at least one, in particular two, plug-in elements of a closure device. The plug element of the closure device can be identical in particular to the plug-in elements, which are also used for the connecting elements. Preferably, two such plug-in elements are provided, which are in particular horizontally spaced from each other and their distance from one another correspond to a distance of receiving elements of an obstacle element. By attaching such a rung element, a wall bar can be produced with the aid of an obstacle element, in particular if a plurality of rung elements are arranged one below the other.

Preferably, a side wall of an obstacle element has a closable opening, which is covered by a closure plate. In this case, the closure plate may be a door. The closure plate may in particular be rotatably mounted on the side wall with one or more hinges. A locking means may lock the locking plate in its closed position. The obstacle elements preferably have an increased weight for their good stability. This weight can be increased in particular by separate ballast material. The obstacle element should be as rigid as possible, so that in particular a cover plate should be firmly connected to the side walls, to support the torsional rigidity of the obstacle element, and is therefore not removable in particular. In order nevertheless to gain access to the interior of the obstacle element according to the invention the opening is provided with the closing plate. In particular, a type of door can thus be created which releases a possibility for loading the interior with ballast material. Consequently, the invention also relates to such an obstacle element alone, which can be connected to another obstacle element to a Parkouraufbau according to claim 1.

All obstacle elements can in principle be designed as described with respect to the first obstacle element.

The FIGS. 1 to 4 will be described together below. An inventive Parkouraufbau 10 includes five obstacle elements 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ and 11 _fifth Between two obstacle elements 11 diverse connecting elements 13 are arranged. The connecting elements 13 are firmly connected to a respective closure device with at least one of the obstacle elements 11. Although the individual obstacle elements 11, in particular the first obstacle element 11 ₁ , which is the largest volume of the obstacle elements by volume, already by their size and weight have a certain stability, which are required for the implementation of exercises on the Parkouraufbau. By connecting the obstacle elements with each other by the connecting elements 13, an additional stability of the obstacle elements 11 is provided. The obstacle elements 11 are essentially cuboid components which have four side surfaces 17. Between two side surfaces 17 each edges 30 are arranged. The edges 30 are rounded to reduce the risk of injury.

There are different connecting elements 13 are provided. Thus, between the first obstacle element 11 ₁ and the second obstacle element 11 ₂ two bar spars 13 ₃ at the same height but offset in the width direction to each other. The bar spars have a round cross-section and therefore can transmit forces well in a direction other than the vertical direction. Between the first obstacle member 11, and the third obstacle member 11 ₃ a turn bar 13 _{1 is} arranged. The Turnbalken 13 ₁ has a square cross-section. The turnbuckle 13 ₁ is designed to be able to absorb large forces, which may in particular also result from jumping down from the first obstacle element 11 ₁ onto the turntable 13 ₁ .

Between the second obstacle element 11 ₂ and the fourth obstacle element 11 ₄ , a rising beam 13 _{4 is} arranged, on which a balancing on a rising surface can be performed. Between the fourth obstacle element 11 ₄ and the fifth obstacle member 115, a stretch rod 13 _{2 is} arranged. All connecting elements 13 are fastened via a closure device 12 to side surfaces 17 on obstacle elements. The closure device 12 is based on the FIGS. 3 to 7 described in detail below. The first obstacle element 11 ₁ has a length and a width of 1.0 m each. The height is 2.0 m. The weight of the first obstacle element 11 ₁ is 80 kg. The first obstacle element 11 ₁ is largely made of multiplex plates, which also form the side surfaces 17. The multiplex panels are coated with a weatherproof layer, so that the obstacle element 11 is protected against rainwater. The surface of the side surfaces 17 is further provided with a sanding, which gives the side surfaces 17 a rough surface. Due to the rough surface, the obstacle elements 11 can be climbed more easily. Lower edges of the side surface 17 form a standing device 18 for supporting the obstacle element 11 on the ground. On the obstacle member 11, a cover 19 is provided, which closes the obstacle member 11 above. On side surfaces 17 of the first obstacle member 11 _{1 a} plurality of receiving elements 20 of the closure devices 12 are provided. In each case five receiving elements 20 are arranged side by side per side surface in two vertical rows. In this respect, forty receiving elements 20 are provided on the first obstacle element 11. Due to the large number of receiving elements 20, a flexible application of connecting elements 13 on the first obstacle element 11 _{1 is} possible. The other obstacle elements 11 ₂ to 11 ₅ have substantially the same structure as the first obstacle element 11 ₁ , with variations in size and weight are possible.

The receiving element 20 is in FIG. 3 illustrated in more detail. The receiving element 20 is represented by a receiving opening 15 in the side surface 17. The receiving opening 15 is geometrically represented by a first vertically aligned slot 27, which is crossed with a second horizontally arranged slot 28. The second slot 28 is aligned centrally with respect to the first slot 27, whereas, on the other hand, the first slot 27 is aligned vertically downwardly offset from the second slot 28. Overall, a cross-shaped receiving opening 15 results. The receiving element 20 is part of the closure device 12, which further comprises a plug-in element 21, which in FIG. 4 is shown. The plug-in element 21 comprises a main body 14, which comprises a cylindrical basic shape with a square plan. At one end of the cylindrical base body 14, for example, a stretch rod 13 ₂ is integrally formed as a connecting element. However, other connecting elements can also be provided which can also be connected to the base body 14 by a separate joining process.

The main body 14 is performed for mounting substantially through the first slot 27 of the receiving element 20, wherein a width of the base body 14 substantially corresponds to a width of the first slot 27. It can be seen that the base body 14 can assume different vertical positions within the first slot 27. The plug-in element 21 has a blocking device 16 on an end of the main body 14 facing away from the connecting element 13 ₂ . The blocking device 16 in this case comprises a blocking rule 26 which protrudes perpendicularly on two sides laterally from the main body 14. The blocking bar 26 is cylindrical, with a circular base. The blocking bar 26 is aligned substantially transversely to the cylindrical base body 14, wherein the base body 14 is aligned longitudinally to an insertion direction E of the plug element 21 in the receiving element 20. A length of the locking bar 26 substantially corresponds to a length of the second slot 28 of the receiving element 20, wherein the blocking bar 26 can be passed through the second slot 28. It can be seen, however, that the blocking bar 26 can only be passed through the second slot 28 when the cylindrical base body 14 is held in a vertically upper orientation in the first slot 27. This orientation of the base body 14 corresponds to the release position of the plug-in element 21. If the Biockierriegel is passed through the second slot 28 and then the plug element 21 is guided in the lower vertical position, the plug element 21 is in the blocking position, since the blocker block 26 prevents displacement of the plug member 21 from the receiving opening 15 out. In this case, a first blocking surface 23 is supported on an inner side of the wall 17 forming the side surface. A displacement of the plug element 21 further into the receiving opening 15 is prevented by second blocking surfaces 24 of the plug element 21, which can be supported on an outer surface of the side surface 17 forming wall. In the blocking position, a contact surface 25 of the main body 14 is also supported on a horizontally arranged receiving surface 31. Above the contact surface 25 and the receiving surface 31 are transmitted vertically acting forces from the connecting element 13 directly on the side surface 17 supporting wall.

The FIGS. 5 to 7 will be explained together below. The closure device 12 shown has a securing device 29. The securing device 29 in this case comprises a securing body 32, which has a portion 33 which can be inserted into the receiving opening 15 in a form-fitting manner. The section 33 is formed substantially complementary to the second slot 28.

In this case, a positive movement of the securing body 32 in the plane of the side surface 17 is prevented.

The fuse body 32 in this case has a rigid locking surface 34, which is firmly connected to the portion 33. Furthermore, the securing device has movable securing surfaces 35, which are connected to separate securing elements 36 via bolts 37 rotatably connected to the fuse body 32. The rigid locking surface 34 may, when the portion 33 is disposed in the receiving opening 15, be in abutment with the side surface 17. Then, moving the section 33 further into the receiving opening 15 is prevented by the rigid securing surface 34. While the movable securing surfaces in FIG. 35 are arranged in an engaged state, as in FIG FIG. 6 shown, the fuse body can be guided into the receiving opening 15 until the rigid locking surfaces 34 are in contact with the side surface 17. Subsequently, the movable locking surfaces 35 can be rotated in the disengaged state. Then the securing elements 36 engage behind the wall carrying the side surface 17, so that the movable locking surfaces 35 are in contact or almost in contact with the wall. A relative movement in the insertion direction E of the fuse body 32 is thus prevented. The bolts 37 have on the rigid locking surface 34 assigned to side engagement means in which a tool can engage. Thus, for example, with a Allen tool twisting of the bolt 37 can be accomplished.

In FIG. 5 it can be seen that the connecting element 13 is in the Bocking position. It is, in the illustration according to FIG. 5 not recognizable, behind the side surface 17 of the locking bar 26 is arranged. A displacement of the connecting element to vertically above, so that the locking bar 25 may come into top-notch with the second slot 28 is prevented by the securing body 32 which is arranged in the slot 28. This ensures that the connecting element 13 is not unintentionally released from the obstacle element 11.

In FIG. 8 is an obstacle elements 11 shown, which for the Parkouraufbau after FIG. 1 suitable is. For improved stability, the obstacle member has a support plate 38 which is substantially completely mounted on the underside of the obstacle member and by two vertical side surfaces 17, namely the largest vertical side surfaces 17, protrudes vertically. When the athlete comes to an edge of this support plate 38 there is an increased risk that the athlete will fold over the foot. Therefore, a cover plate 39 is mounted on one of the projecting portions of the support plate, the This area of the support plate substantially completely covers. The cover plate 39 is arranged at an angle of 45 ° to the horizontal is. As a result, the risk of Abcknickens the foot when occurring significantly reduced.

In the FIGS. 9a and 9b an obstacle member 11 is shown on the side of an obstacle member 13 in the form of z. B. a stretch rod is attached. This obstacle element 11 is arranged in the vicinity of a wall bar with several rungs 42. On the wall bars 42, a wall adapter 40 is attached.
