Description

[0001] The present invention relates to a column for a stretching system, according to the preamble of claim 1. The invention also relates to a stretching system and a climbing system, each of which is equipped with a plurality of such columns.

[0002] Horizontal bar systems are generally known from school sports and comprise several ground sockets firmly anchored in a floor, usually the floor of a sports hall, as well as several columns and several horizontal bars. To assemble the horizontal bar system, the columns are inserted into the ground sockets and the horizontal bars are attached to adjacent columns. Such a column can have a rectangular column cross-section and four outer sides. The horizontal bars can be attached to the columns using horizontal bar openings, which are formed for this purpose on two outer sides of the column that face away from each other in a first transverse direction of the column and are adjacent to each other in a longitudinal direction of the column, allowing the horizontal bar to be attached to the column at different heights. Once the horizontal bar system is assembled, people (male / female / diverse) can do gymnastics on the bars or perform other physical exercises, such as pull-ups.

[0003] A problem in sports, especially school sports, and especially indoor sports, is people's motivation to perform physically demanding exercises. One approach to improving motivation in sports is to vary the exercises and / or design them in such a way that different aspects of physical and mental fitness are addressed simultaneously.

[0004] From US 2016 0 023 035 A1, a generic column and a stretching system equipped therewith are known, wherein the column is configured such that it can be releasably inserted into one of the ground sleeves, wherein the column has a rectangular column cross-section, four column outer sides, a column longitudinal direction, a first column transverse direction and a second column transverse direction running transversely to the first column transverse direction, wherein the column has a plurality of stretching openings at least on the two column outer sides facing away from one another in the first column transverse direction or in the second column transverse direction, which are adjacent to one another in the column longitudinal direction and with the aid of which the stretching rod can be releasably fastened to the column.In the known stretching system, each stretching rod has a sleeve at its longitudinal ends, which has an inner cross-section matching the outer cross-section of the respective column, so that the sleeve can be adjusted along the column in the manner of a slide.

[0005] From DE 298 06 385 U1 a gymnastics wall is known in which a central wall element is adjustably mounted on two lateral wall elements by means of a slide.

[0006] DE 10 2022 108 413 A1 discloses a multi-purpose groove profile for a pit cover for covering a tool bed of a machine tool.

[0007] CN 219 462 416 U discloses a stretching system with two supports for setting up the stretching system on a floor and with a stretching rod which extends between the two supports and is arranged on the two supports so that its height is adjustable.

[0008] A base plate for a column of a fence element is known from DE 201 02 323 U1.

[0009] DE 297 08 698 U1 discloses a column lowering device which has a guide tube embedded in a foundation and a sliding bushing adjustable in the guide tube for receiving a column.

[0010] The present invention addresses the problem of providing an improved embodiment for a column or for a horizontal bar or climbing facility equipped therewith, which is characterized in particular by more variety for the people practicing the sport.

[0011] This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

[0012] The invention is based on the general idea of ​​designing the column in such a way that, in addition to the horizontal bars, other components or equipment can be attached to the column, while providing the greatest possible flexibility with regard to positioning along the column. This makes it possible to attach other sports equipment to the columns of the horizontal bar system in addition to or instead of the horizontal bar, such as a so-called slackline, which is a band stretched at a distance from the ground on which the person can balance.

[0013] Specifically, the invention proposes equipping the column at least on one of the outer sides with a rail that is configured to hold and guide a carriage of complementary design, extends in the longitudinal direction of the column, and is designed as an undercut contour. The undercut contour is configured such that the carriage, which is designed to be complementary to the rail, when positively engaged with the undercut contour, is adjustable in the longitudinal direction of the column and is held positively on the column in a first transverse direction of the column and in a second transverse direction of the column running transversely to the first transverse direction of the column. The transverse directions of the column extend perpendicular to one another and perpendicular to the longitudinal direction of the column. The column is elongated and straight and defines the longitudinal direction of the column.This allows the carriage to be adjusted in the longitudinal direction of the column, but is attached to the column via the rail at right angles to the longitudinal direction of the column.

[0014] In the present context, a ‘configuration’ is synonymous with a ‘design’, so that the phrase ‘configured so that’ is synonymous with the phrase ‘designed so that’.

[0015] The undercut contour defines a clearance on the outer side of the respective column that is available to the slide for positive engagement. The undercut contour thus specifies the matching, complementary contour of the slide and thus defines the slide.

[0016] Since the slide inserted into the rail cannot be removed from the column perpendicular to the column's longitudinal direction, it generally cannot be inserted into the rail perpendicular to the column's longitudinal direction either. It is advisable to have the rail open at at least one longitudinal end of the column, so that the respective slide can be inserted into or removed from the rail at this open longitudinal end in the column's longitudinal direction.

[0017] A particularly advantageous design is one in which the cross-sectional profile is square. This simplifies handling of the columns during assembly of the stretching system.

[0018] In a first solution according to the invention, the respective rail has an outwardly open chamber on the respective outer side of the column and a guide body protruding into the chamber. The chamber has a chamber opening on the outer side of the column, whereby the chamber is open to the outside. Furthermore, the chamber is delimited by two wall sections which are formed on the outer side of the column in two corner regions of the column cross-section and which are located in the column cross-section transversely to the longitudinal direction of the column on both sides of the guide body and each extend in the column cross-section from the guide body to the chamber opening. The two wall sections thus form a lateral border for the guide body. The two wall sections, together with the guide body in the chamber, form the undercut contour.In other words, the carriage rests on the guide body and the wall sections perpendicular to the column's longitudinal direction, allowing the carriage to be guided along the column's longitudinal direction and along the wall sections, while being held on the column transversely to the column's longitudinal direction by the guide body and / or the wall sections. This results in a particularly simple structure for the rail on the outer side of the respective column.

[0019] According to the invention, the guide body is T-shaped in its column cross-section. This allows the guide body itself to form undercuts that are part of the undercut contour. In particular, this allows for additional support of the carriage on the guide body transverse to the column's longitudinal direction.

[0020] According to an advantageous embodiment, the wall sections can each have an edge region that defines the chamber opening and protrudes outward beyond the guide body. This allows the guide body to be recessed within the chamber and thus does not form an interfering contour on the outside of the column, while simultaneously protecting it from damage when handling the columns.

[0021] Additionally or alternatively, the respective edge area can protrude from the corner area toward the guide body. This creates an undercut between the respective wall section and the edge area, which forms a component of the undercut contour and can be used to positively support the carriage transversely to the column's longitudinal direction. In principle, this design can also provide sufficient hold for the carriage in the rail with an I-shaped guide body that does not form an undercut. However, the T-shaped guide body with the additional undercuts is preferably used here to improve the carriage's hold in the rail.

[0022] In another embodiment, the respective rail can have a plurality of slide openings that are adjacent to one another in the longitudinal direction of the column and with the aid of which a position of the slide received in the rail can be fixed with respect to the longitudinal direction of the column. For example, the slide can be provided with a bolt that can engage positively in such a slide opening in order to fix the position of the slide on the column with respect to the longitudinal direction of the column. The arrangement of the slide openings thus predetermines different positions for the slide. Alternatively, an embodiment is also conceivable in which the slide is equipped with a clamping device so that the slide can be clamped at virtually any position along the column with the undercut contour in order to fix the slide with respect to the longitudinal direction of the column.In this case, the slide openings can generally be dispensed with.

[0023] An advantageous embodiment is one in which the slide openings are formed on the guide body. The guide body can be characterized, in particular, by a greater wall thickness, thus achieving particularly high stability for securing the slide.

[0024] In another embodiment, the column can have four corner areas in its cross-section, where two outer sides of the column merge into each other. The stretching openings, which can be used to attach the respective stretching rod to the column, can then be conveniently located in these corner areas. This embodiment ensures that the rail can be used completely independently of the stretching openings, thus creating a particularly high degree of freedom in the use of the rail and thus the column.

[0025] The column can expediently have such a rail on at least the two outer sides facing away from each other in the first column transverse direction or in the second column transverse direction. This allows the two outer sides of the column, each equipped with such a rail, to be used in conjunction with the carriage for attaching other components or devices.

[0026] A particularly advantageous embodiment is one in which the column has several stretching openings on each of its four outer sides, adjacent to each other in the longitudinal direction of the column, and with the aid of which the stretching rod can be releasably attached to the column. This allows the respective stretching rod to be attached to the column on each outer side, which improves the flexibility of the column for use in a stretching system.

[0027] It can be expediently provided that the stretching openings are formed only in one longitudinal section of the column, preferably in a longitudinal section that encompasses an upper end of the column when the column is erected, i.e., when inserted into the respective ground sleeve. Alternatively, the stretching openings can be distributed along the entire length of the column, so that the column can be equipped with a stretching rod along its entire length.

[0028] A particularly useful design is one in which the column has such a rail on each of its four outer sides. This allows each outer side of the column to be used to attach a different component or device, improving the flexibility of the column's usability within the stretching system.

[0029] According to an advantageous embodiment, the column can be designed as a hollow profile, so that the column cross-section has a cross-sectional profile with at least one hollow space. A particularly advantageous configuration is one in which the respective rail is integrally formed on the column, so that a section of the cross-sectional profile forms the respective rail. This makes it particularly easy to incorporate the respective rail during column production and thus manufacture it simultaneously. The hollow profile of the column can be manufactured with the desired cross-sectional profile as an extruded profile, extruded profile, or continuous-cast profile.

[0030] According to an advantageous development, the cross-sectional profile of the column cross-section can have multiple cavities. Alternatively, a configuration is also conceivable in which the cross-sectional profile of the column cross-section has only a single cavity.

[0031] In a second solution according to the invention, the cross-sectional profile has a central cavity and four outer cavities, each located outside the central cavity and each in a corner region of the column cross-section. A cross-sectional profile with multiple cavities is characterized by significantly greater stability and rigidity than a cross-sectional profile with only a single cavity. This is due to the fact that in order to form multiple cavities within the cross-sectional profile, corresponding webs must be formed in order to delimit the respective cavity transversely to the longitudinal direction of the column. These webs ensure intensive stiffening of the column. The outer cavities, for example, significantly strengthen the corner regions of the column cross-section, which favors their use for attaching the stretching openings and thus for holding the stretching rod.At the same time, the inner or central cavity becomes smaller in cross-section and thus more stable, which stiffens the respective rail.

[0032] The column can be equipped with a fastening device for detachable insertion into the respective ground socket. This fastening device can be configured, for example, as a locking device that creates a locking connection between the column and the ground socket, or as a clamping device that clamps the column in the ground socket.

[0033] According to a preferred embodiment, the column can be designed as a stretching column having a first end section with respect to the column's longitudinal direction, which forms a lower end section when the column is inserted into the respective ground sleeve, and a second end section spaced apart from the first end section in the column's longitudinal direction, which second end section forms an upper end section when the column is inserted into the respective ground sleeve, wherein at least the first or lower end section is configured such that the column can thereby be detachably inserted into the respective ground sleeve, while the stretching openings are formed at least in the second or upper end section. The end sections of the column can thus be designed differently, so that they differ from profile bars that have identical end sections. For example, the first or lower end section can be equipped with the fastening device mentioned above.In particular, the column can also have a central section located between the two end sections with respect to the column's longitudinal direction. Preferably, only the first or lower end section can be configured such that the column can thus be releasably inserted into the respective ground sleeve. The second or upper end section cannot then be inserted into the respective ground sleeve. Additionally or alternatively, the stretching openings can be formed exclusively in the second or upper end section. The first or lower end section then has no stretching openings. The central section, if present, also has no stretching openings.

[0034] A column set according to the invention comprises a column of the type described above and at least one carriage complementary to the respective rail, which carriage can be inserted into the respective rail of the column so that it can be adjusted therein in the longitudinal direction of the column and is held positively on the column transversely to the longitudinal direction of the column.

[0035] A stretching system according to the invention has a plurality of ground sleeves that are firmly anchored in a floor. The stretching system has at least two columns of the type described above, each of which can be releasably inserted into one of the ground sleeves. Furthermore, the stretching system has at least one stretching rod that can be releasably fastened to two adjacent columns using the stretching openings. In addition, the stretching system is equipped with at least one carriage that is arranged in one of the rails so that it can be adjusted in the longitudinal direction of the column. It is clear that the stretching system can usually have significantly more than two columns, as well as several stretching rods and several carriages. For example, at least ten columns, at least ten stretching rods, and at least ten carriages can be provided. The floor can expediently be provided with at least ten ground sleeves.

[0036] A particularly advantageous configuration is one in which the respective sled has a fastening element with which another component or device can be attached to the sled. Such a fastening element can be, for example, a bracket or a ring to which a hook or carabiner can be attached. The other component or device can, in particular, be a piece of sports equipment, such as a slackline or a climbable and / or walkable obstacle. Examples of climbable or walkable obstacles include nets or grids suspended vertically between two pillars, or hanging boards, ropes, or beams.

[0037] Additionally or alternatively, the slide can have a locking pin that is adjustable between a retracted, unlocked position and an extended, unlocked position on the slide. In the unlocked position, the locking pin engages a slot on the column to fix the slide's position relative to the column's longitudinal direction. The locking pin thus allows for a positive locking of the slide to the column in the column's longitudinal direction. The locking pin can be a spring-loaded pin in the locked position. The locking pin can also be configured as a threaded pin that is rotatably adjustable between the locked position and the unlocked position.

[0038] A climbing structure according to the invention has a plurality of ground sockets which are firmly anchored in the ground, and is equipped with a plurality of pillars of the type described above, each of which is detachably inserted into one of the ground sockets. The climbing structure has a plurality of sleds which are arranged in the rails of the pillars. The climbing structure is also equipped with a plurality of different climbable or walkable obstacles, each of which is assigned to at least two pillars. The respective obstacle is attached to the pillars assigned to the respective obstacle using the sleds in such a way that a person can climb or walk from one pillar assigned to the respective obstacle over the respective obstacle to the other pillar assigned to the respective obstacle. Such climbable or walkable obstacles are, for example, nets or ropes or boards or beams stretched between the pillars.Walkable obstacles are known, for example, from rope courses or high ropes courses.

[0039] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0040] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention defined by the claims. Components mentioned above and to be mentioned below of a higher-level unit, such as a device, apparatus, or arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0041] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0042] They show, schematically, Fig. 1 is an isometric view of an end portion of a column in a first embodiment, Fig. 2 a view as in Fig. 1, but in a second embodiment of the column, Fig. 3 a cross-section of the column from Fig. 2 in the area of ​​a horizontal bar, Fig. 4 an isometric view of a sled, Fig. 5 an isometric view of a stretching machine with two columns, Fig. 6 an isometric view of a climbing structure with several columns, Fig. 7 an isometric view of the column in the region of a first or lower end section.

[0043] According to the Fig. 1 to 3 and 7, a column 1 comprises a rectangular column cross-section 2, four column outer sides 3, a column longitudinal direction X, a first column transverse direction Y1 and a second column transverse direction Y2. The column 1 is elongated and straight, so that it has a longitudinal central axis 4 which defines the column longitudinal direction X. The column longitudinal direction X extends parallel to the column longitudinal central axis 4. The first column transverse direction Y1 extends perpendicular to the column longitudinal direction X. The second column transverse direction Y2 extends perpendicular to the column longitudinal direction X and perpendicular to the first column transverse direction Y1. In the embodiments shown here, the column cross-section 2 is square.

[0044] The column 1 has at least on the two column outer sides 3 facing away from each other in the first column transverse direction Y1, a plurality of stretching openings 5 ​​which are adjacent to each other in the column longitudinal direction X and with the aid of which a Fig. 3 partially shown stretching rod 6 can be detachably attached to the column 1. The stretching rod 6 properly attached to the column 1 then extends in the second column transverse direction Y2. In this case, the stretching rod 6 uses a stretching opening 5 on each of the two column outer sides 3, which face away from each other in the first column transverse direction Y1, for its attachment to the column 1. For example, the stretching rod 6 according to Fig. 3 has a U-shaped bracket 7 at its respective longitudinal end, which overlaps the column 1 in the area of ​​the stretching openings 5. A plug pin 8 is formed on the bracket 7, which is fixed to the outer side of the column 3, which is in Fig. 3 is located at the top, is inserted into one of the stretching openings 5. The bracket 7 has a screw bolt 9 opposite the plug bolt 8, which is attached to the opposite outer side of the column 3, which is in Fig. 3 is located at the bottom, is screwed into the corresponding opposite stretching opening 5. The stretching rod 6 is thus positively fixed to the column 1 via the stretching openings 5.

[0045] According to the Fig. 1 to 3 and 7, the column 1 has a rail 10 on at least one of the column outer sides 3, which is configured to hold and guide a carriage 11 of complementary design. The rail 10 extends in the column longitudinal direction X over the entire length of the column 1 and is designed as an undercut contour 12. This undercut contour 12 is configured such that the carriage 11, which is designed complementary to the rail 10, when it is in positive engagement with the undercut contour 12, is adjustable or displaceable in the column longitudinal direction X along the column 1, while it is held on the column 1 in a positive-fitting manner transversely to the column longitudinal direction X.

[0046] According to the Fig. 1 to 3 and 7, the respective rail 10 can have an outwardly open chamber 13 on the respective column outer side 3 and a guide body 14 protruding into the chamber 13. The outwardly open chamber 13 has a chamber opening 15 on the column outer side 3. Furthermore, the chamber 13 is delimited by two wall sections 16, which are formed on the column outer side 3 in two corner regions 17 of the column cross-section 2. The wall sections 16 are located in the column cross-section 2 transversely to the column longitudinal direction X on both sides of the guide body 14 and here extend in the column cross-section 2 from the guide body 14 to the chamber opening 15. The wall sections 16, together with the guide body 14, form the undercut contour 12 in the chamber 13.

[0047] The guide body 14 is expediently T-shaped in the column cross-section 2, whereby the complementary slide 11 can engage positively with the guide body 14. In particular, the slide 11 can engage behind the guide body 14 so that the slide 11 can no longer be withdrawn from the guide body 14 transversely to the column longitudinal direction X. The wall sections 16 each have an edge region 18 delimiting the chamber opening 15.

[0048] At the Fig. In the first embodiment of the column 1 shown in Fig. 1, the guide body 14 projects into the chamber 13 to such an extent that the guide body 14 ends flush with the edge regions 18 on the respective column outer side 3.

[0049] In other words, the edge regions 18 and the guide body 14 are located on the respective column outer side 3 in the same plane. Furthermore, in the example of the Fig. 1, the wall sections 16 are essentially L-shaped.

[0050] In contrast, the Fig. 2 and Fig. 3 and 7 show a second embodiment of the column 2, in which the edge regions 18 project outwards beyond the guide body 14, so that the guide body 14 is recessed or offset inwards in the chamber 13 relative to the respective column outer side 3. Furthermore, the edge regions 18 in this second embodiment project from the corner region 17 in the direction of the guide body 14, thereby forming an additional undercut within the undercut contour 12, against which the carriage 11 can be supported transversely to the column longitudinal direction X. In the example of Fig. 2, the wall sections 16 are essentially C-shaped.

[0051] According to the preferred embodiments shown here, the respective rail 10 can have a plurality of slide openings 19 which are adjacent to one another in the column longitudinal direction X and with the aid of which a position of the slide 11 received in the rail 10 can be fixed with respect to the column longitudinal direction X. For example, the slide 11 can have a bolt for this purpose which engages in the respective slide opening 19 in order to effect the desired fixation in the column longitudinal direction X by means of a positive fit. The slide openings 19 are expediently formed on the guide body 14, which is characterized by a particularly high wall thickness compared to the other components of the column cross-section 2.

[0052] The column 1 has four corner regions 17 in the column cross-section 2, in each of which two column outer sides 3 merge into one another. The rail 10 is expediently located on the respective column outer side 3 between two such corner regions 17, so that the slide openings 19 are also located between the two corner regions 17. In contrast, the stretching openings 5 ​​are formed in the corner regions 17. In this way, an undesirable interaction between the stretching openings 5 ​​and the slide openings 19 or between the stretching rod 6 and the slide 11 can be avoided. This means that a stretching rod 6 and at least one slide 10 can be arranged on the same column outer side 3.

[0053] In the example of Fig. 1, the column 1 has such a rail 10 only on the two outer sides 3 of the column, which are facing away from each other in the second column transverse direction Y2. In this column 1, the horizontal bar 6 can also only be attached to these two outer sides 3 of the column. Accordingly, in the Fig. 1, the stretching openings 5 ​​are only on the two other column outer sides 3, which face away from each other in the first column transverse direction Y1.

[0054] The Fig. 2, Fig. 3 and Fig. 7 show another embodiment of the column 1, in which all four column outer sides 3 are constructed identically. Thus, there are several stretching openings 5 ​​on each of the four column outer sides 3, so that the stretching rod 6 can be attached to the column 3 on each column outer side 3. Furthermore, the column 1 in the Fig. 2 and Fig. 3 and 7, each of the four outer sides 3 of the column has such a rail 10.

[0055] According to the Fig. 1 to 3 and 7, the column 1 is designed as a hollow profile, so that the column cross-section 2 has a cross-sectional profile 20 in which at least one cavity 21 is formed. As can be seen, the respective rail 10 is integrally formed on the column 1. Consequently, a section of the cross-sectional profile 20 forms the respective rail 10.

[0056] In the example of Fig. 1, the cross-sectional profile 20 of the column cross-section 2 has only a single cavity 21. In contrast, the Fig. 2 and Fig. 3 shows an embodiment in which the cross-sectional profile 20 of the column cross-section 2 has several cavities 21. In the Fig. 2, Fig. 3 and Fig. 7 each have five cavities 21, namely a central cavity 21' and four outer cavities 21''. The outer cavities 21'' are each arranged outside the central cavity 21' and each in one of the corner regions 17 of the column cross-section 2.

[0057] According to the Fig. 5 and Fig. 6, a stretching system 22 has a plurality of ground sleeves 23 that are firmly anchored in a floor 24. When the stretching system 22 is not assembled, the ground sleeves 23 are closed with a cover (not shown here) flush with the floor 22. The stretching system 22 is preferably used in a hall, so that the floor 24 with the ground sleeves 23 is formed by a hall floor.

[0058] The stretching system 22 has at least two columns 1 of the type described above, which can be releasably inserted into one of the ground sleeves 23 to assemble the stretching system 22. Furthermore, the stretching system 22 comprises at least one stretching rod 6 of the type described above. Fig. 6 shows two such stretching rods 6, installed within the stretching system 22. Each stretching rod 6 is visible attached to two adjacent columns 1.

[0059] Fig. 6 also shows that the columns 1 are each provided with the stretching openings 5 ​​only in an upper longitudinal section 25, so that the stretching rods 6 can only be mounted in the upper longitudinal section 25 of the columns 1. This upper longitudinal section 25 provided with the stretching openings 5 ​​is in Fig. 6 is marked with a curly bracket only on one column 1.

[0060] According to Fig. 6, the respective column 1 is preferably designed as a stretching column 1', which has a first end section 41 and a second end section 42, which are facing away from each other in the column longitudinal direction X. In addition, a middle section 43 can be present, which is located between the two end sections 41, 42 with respect to the column longitudinal direction X. When the column 1 is inserted into the respective ground sleeve 23, the first end section 41 forms a lower end section 41', while the second end section 42 forms an upper end section 42'. The different sections 41, 41', 42, 42', 43 of the column 1 are in Fig. 6 is marked purely by way of example only on one of the columns 1 by curly brackets. Furthermore, on this one column 1, a plug-in section 44 inserted into the respective ground sleeve 23 is indicated by a broken line.

[0061] It is now expediently provided that only the first or lower end section 41, 41' is configured in such a way that the column 1 can thus be releasably inserted into the respective ground sleeve 23. Fig. 7 shows a possible configuration of the first or lower end section 41, 41' with the plug-in section 44. As can be seen, a fastening device 45 is formed on the first or lower end section 41, 41', which is configured to secure the column 1 inserted into the ground sleeve 23 to the ground sleeve 23. In the example shown, the fastening device 45 comprises a bolt 46 adjustable transversely to the column longitudinal direction X and a handle 47 for manually adjusting the bolt 46. For this purpose, the handle 47 is coupled to the bolt 46 in a suitable manner inside the column 1. For example, with the aid of the handle 47, the bolt 46 can be driven to lock or clamp the column 1 in the ground sleeve 23 in order to thus secure the column 1 inserted into the ground sleeve 23 to the ground sleeve 23.

[0062] According to Fig. 6, the second or upper end section 42, 42', in contrast, does not have such a fastening device 45. Therefore, in the example shown, the stretching openings 5 ​​are preferably formed exclusively in the second or upper end section 42, 42', so that no stretching openings 5 ​​are present in the first or lower end section 41, 42 or in the middle section 43. In contrast, the rail openings 19 are not limited to the second or upper end section 42, 42'. In particular, the rail openings 19 can extend substantially over the entire column 1 in the column longitudinal direction X.

[0063] In an embodiment not shown, the stretching openings 5 ​​can extend in the column longitudinal direction X substantially over the entire column 1. This allows for additional fastening options for the stretching rods 6 or for other components that are equipped with fastening devices compatible with the stretching openings 5, such as a hanging ladder 35 mentioned below.

[0064] The stretching system 22 presented here has at least one carriage 11, which is arranged in one of the rails 10 so as to be adjustable in the column longitudinal direction X. In the example of the Fig. 5, only two columns 1 are visible, the outer sides 3 of the columns facing each other each having a carriage 11 in the rail 10 there. The respective carriage 11 is fixed comparatively far down, i.e., near the floor 24 on the respective column 1 with respect to the column longitudinal direction X.

[0065] The respective carriage 11 can be moved according to Fig. 1 may have a fastening element 26, which may be configured, for example, as a bracket. Using this fastening element 26, another component 27 or a device 27, preferably a piece of sports equipment 27, can be attached to the slide 11. For example, the component 27 may have a hook or snap hook that complements or matches the fastening element 26 and can be secured or hooked onto the fastening element 26.

[0066] The carriage 11 can be moved according to the Fig. 1, Fig. 2 and Fig. 4 have a safety bolt 29 which can be moved between a retracted release position and a Fig. 4 is adjustable and arranged on the slide 11 in the extended securing position. In the securing position, the securing bolt 29 engages in a form-fitting manner in one of the slide openings 19, whereby the respective position of the slide 11 on the column 1 is fixed with respect to the column longitudinal direction X. The securing bolt 29 can be spring-loaded into the securing position. A handle element 30 simplifies the adjustment of the securing bolt 29 against the spring force into the unlocked position in order to move the slide 11 manually along the rail 10. As soon as the securing bolt 29 is located in front of a slide opening 19, the spring force drives the securing bolt 29 into the slide opening 19 so that it locks into place. It is also conceivable to design the securing bolt 29 as a screw bolt so that it has an external thread that engages in a matching internal thread formed on the slide 11.The screw bolt 29 can then be rotated via the grip element 30 to adjust it between the safety position and the release position. With a safety bolt 29 designed as a screw bolt, the slide openings 19 can generally be omitted, since the screw bolt 29 can be used to clamp the slide 11 to the undercut contour 12 at any desired position along the rail 10.

[0067] According to Fig. 4, the carriage 11 has a counter-contour 36 which is complementary to the undercut contour 12 and which cooperates in a form-fitting manner with the guide body 14 and with the wall sections 16. The counter-contour 36 can have an inner contour 37 which is designed complementary to the guide body 14 and which receives the guide body 14 when the carriage 11 is inserted into the rail 10. The inner contour 37 can be formed by a T-shaped cutout 38 which is shaped complementary to the T-shaped guide body 14 and into which the securing bolt 29 protrudes. The counter-contour 36 can also have an outer contour 39 which is designed complementary to the wall sections 16 and which is received by the wall sections 16 when the carriage 11 is inserted into the rail 10.

[0068] In the example of Fig. 5, a slackline 28 is attached as a further component 27 using the two slides 11 and their fastening elements 26, which is stretched above the floor 24 between the two columns 1.

[0069] At the Fig. 6, the horizontal bar system 22 is designed as a climbing system 31, which is characterized by the use of several different climbable and / or walkable obstacles 32. The climbable or walkable obstacles 32 can also be represented by climbable and / or walkable sports equipment 27. Each obstacle 32 is assigned to at least two columns 1, to which the respective obstacle 32 is attached by means of the slides 11. The arrangement of the obstacles 32 on the columns 1 is such that a person can climb and / or walk from one column 1 assigned to the respective obstacle 32 over the respective obstacle 32 to the other column 1 assigned to the respective obstacle 32. In the example of Fig. 6, the climbing facility 31 comprises nine columns 1, of which only six columns 1 are in use for a course. One obstacle 32 is in the example of the Fig. 6 is formed by a net 33. The other obstacle 32 can again be formed by a slackline 28.

[0070] In the climbing facility 31, the rails 10 with the slides 11 are used in combination with the horizontal bars 6 to form the course. One horizontal bar 6 is used unchanged as a bar for hanging, while the other horizontal bar 6 is provided with rings 34 to create another climbable obstacle 32. Furthermore, in the example of the Fig. 6 shows how, with the aid of the openings 5, a hanging ladder 35 can be attached to the adjacent columns 1 as a further climbable obstacle 32.

[0071] The columns 1 together with at least one such carriage 11 form a column set 40, in which the respective carriage 11 can be inserted or is inserted into the respective rail 10 and is adjustable therein in the column longitudinal direction X and is held transversely thereto in a form-fitting manner on the column 1.
