Definitions
- the invention relates to a scaffolding system with posts and spherical clamps, in which one or more posts are arranged at an angle.
- the spherical clamps are formed of two hemispheres, each with at least two elements, each embracing the post.
- the ball halves of the clamps also have receptacles for inserting add-on parts.
- Playground installations and climbing frames are often assembled from system components.
- the design solutions that can be realized in this way are therefore limited. They often also require a vertical and horizontal alignment of built-in parts such as posts and attachments attached to them, which are aligned at right angles to one another as a result of the use of system parts.
- Such an arrangement is perceived as less creative and stimulating for playing children and also as not very organic, especially when the playground installations and climbing frames are intended to imitate well-known objects or figures, such as a pirate ship. If the arrangement of individual components deviates from the right-angled grid, special solutions are usually required, which are complex and therefore expensive.
- the object of the invention is therefore seen in designing such nodes in such a way that an inclined arrangement of components is possible.
- the object of the invention is achieved with a scaffolding system according to claim 1 and a
- a scaffolding system is formed with posts and spherical brackets, at least one post being inclined at an angle and at least one spherical bracket being arranged on each inclined post, and one spherical bracket respectively
- - is composed of two hemispheres and each of the two hemispheres is formed from the same at least two elements that differ from each other within one hemisphere,
- the at least two elements of each hemisphere include the post
- the equatorial planes formed by the at least two elements of a hemisphere deviate at the angle from a plane perpendicular to the associated post at which that post is inclined in order to align these equatorial planes horizontally
- the elements in the area of the equatorial surfaces of the hemispheres have receptacles for the insertion of at least one attachment.
- the scaffolding system thus has posts and spherical clamps, which are combined in the number required for the scaffolding or the application.
- a post is understood to mean a load-bearing component with a predominant longitudinal extent, which is aligned vertically or whose alignment is primarily oriented vertically.
- At least one of these posts is inclined at an angle to the vertical.
- a post can in particular be tubular or as a hollow body.
- At least one spherical bracket is arranged on an inclined post.
- This spherical clamp is formed from two assembled halves of the sphere, which in turn are each composed of at least two elements. Within a hemisphere, the elements differ due to the inclination of the equatorial surface to be formed and possibly the configuration of the screw connections or other optional configurations, as will be shown below, but the hemispheres are the same as one another. So they consist of structurally identical elements.
- the halves of the sphere each form an upper and a lower half of the sphere and are arranged one above the other in such a way that they form a spherical shape.
- the term hemispheres is not to be understood as a hemisphere in the geometrically correct sense.
- the groupings each correspond to at least two elements in approximately one half of a sphere. They therefore have the appearance of a hemisphere, but deviate from a hemispherical shape in the geometric sense due to the inclined equatorial surface that will be explained later. After assembling the halves of the sphere, which will be explained below, the appearance of a sphere for the spherical clamp is created.
- the at least two elements of a hemisphere include the post. They are shaped and arranged in such a way that they enclose the post when installed.
- the elements of the respective halves of the sphere each have a shape in sections that corresponds to the outer contour of the post, so that the elements of the halves of the sphere bear against the post in this area.
- each half of the sphere each form an equatorial surface.
- this equatorial surface does not extend in a plane which is oriented perpendicular to the inclined post. Instead, it deviates from the plane perpendicular to it by the angle at which the post is inclined. It is thus aligned horizontally when installed, i.e. it is essentially horizontal within the scope of the manufacturing and assembly tolerances.
- the surfaces of the at least two elements facing towards the equatorial plane realize the desired inclination. These surfaces are not formed at right angles to a vertical axis of the respective half of the sphere, but are formed inclined by said angle. This is done in such a way that the adjacent elements of a hemisphere each continue the inclination of the surfaces of the adjacent elements facing the equatorial plane and a common equatorial upper plane is formed as soon as they are put together.
- the two halves of the ball are then placed one on top of the other during assembly in such a way that a closed spherical clamp is formed.
- the hemispheres are rotated relative to one another, independently of the actual assembly, so that the inclination of the equatorial surfaces of the two hemispheres allows the upper equatorial surface to lie flush against the lower equatorial surface.
- the effect of being attached to the inclined post is that the equatorial surface is aligned essentially horizontally.
- each hemisphere is screwed together, i.e. by means of screws connected with each other.
- a clamping effect is also achieved between the at least two elements of a hemisphere and the inclined post, so that the spherical clamp is prevented from slipping off along the inclined post.
- the two halves of the ball are screwed together to secure their relative position to one another.
- At least two screws each are preferably provided for the screw connections. These are screwed through corresponding screw holes in one of the at least two elements of one hemisphere into corresponding threaded bushings in an adjacent element within the hemisphere when the elements of one hemisphere are to be screwed together.
- the screw holes are respectively provided in at least one element of one hemisphere and threaded bushings in at least one element of the other hemisphere which is arranged adjacent to the spherical clamp when the latter is assembled.
- the elements of the hemispheres in the area of the equatorial surfaces have receptacles into which at least one add-on part can be inserted.
- Attachments are also elements of the scaffolding system.
- the receptacles are designed in such a way that they are arranged in half in an element of the lower half of the sphere and in an element of the upper half of the sphere adjacent thereto, with these half receptacles corresponding to one another in position and size and, after assembly, enclosing an inserted attachment or its end.
- the essential idea of the invention is in the scaffolding system according to the invention that the Elements of the two halves of the sphere are the same. So the upper half of the sphere and the lower half of the sphere are the same.
- the inclination in the area of the equatorial surfaces, the screw holes and threaded bushings for screwing the ball halves together and the mounts for attachments are designed, arranged and aligned in such a way that the ball halves can be easily assembled and connected to each other.
- each half of the sphere in this example is formed with an element A and an element B.
- element A and element B of the lower half of the sphere are positioned on the inclined post and bolted together.
- add-on parts can be used or inserted in the receptacles provided.
- the element B of the upper half of the sphere is placed on the element A of the lower half of the sphere and screwed, then the element A of the upper half of the sphere on the element B of the lower half of the sphere.
- the upper half of the sphere is offset from the lower half of the sphere so that element B sits over element A and element A over element B.
- the person skilled in the art will recognize that a similar ball clamp can also be designed without an incline can be.
- the scaffolding system can be formed with further posts and spherical clamps, which can be designed and arranged with other angles of inclination and/or without an inclination.
- the at least one post has a round cross section and the spherical halves of the at least one clamp arranged on it each enclose the post in a ring shape. If the post is formed with a round cross section, it has no edges or corners on which a user of the scaffolding system can hit and injure himself. In addition, a more pleasing appearance is effected in terms of design.
- the spherical clamp which is placed on such a round inclined post, surrounds it in an annular manner.
- the elements of the hemispheres are formed on the surfaces facing the post, based on a plan view, with circular arc sections which, after assembly, form a circle which corresponds to the diameter of the round post. In spatial relation, the inner surfaces form a cylinder through which the post runs.
- a post is arranged at an angle in the range from 2° (degrees) to 12° (degrees), in particular inclined by essentially 5°.
- An inclination in the range of 2° to 12° is already perceived by the eye of the beholder as inclination and deviation from the vertical and allows more diverse designs of playground installations and climbing frames. Larger angles of inclination already place higher demands on the stability and stability of the scaffolding system.
- the at least two elements of one hemisphere have different colors.
- the colors should preferably differ noticeably.
- the respective color serves to identify the individual elements. All elements of a type therefore have the same color. Thanks to the different colors, it is easy and safe to distinguish during assembly which elements are to be put together and which element is to be added to complete the assembly without having to search for printed or embossed markings and/or measure the elements. Accordingly, an assembly can also be carried out using a simple colored template.
- the coloring of the upper and lower half of the sphere is the same, since the same elements are used in both halves of the sphere.
- An attachment is selected from the group tube, handle, decorative element, sun protection, rope, sealing plug.
- An add-on part can be designed in such a way that it is fixed in the spherical clamp by means of a receptacle, but also by means of several receptacles in the same spherical clamp. Some add-on parts have only one attachment point on a clamp, others are attached to several clamps and thus attached.
- a tube as an elongated hollow body can be used, for example, as a horizontal connection between two spherical clamps on two posts, especially inclined posts. So it can form a fall protection, but also a mounting option for panels, decorations and other attachments that are not designed for attachment to a spherical clamp.
- a tube can only have a linear extension, that is to say it can be designed as a straight tube, but it can also be used in curved shapes.
- a handle is an attachment that is used to provide users of the scaffolding system with a hold or to facilitate entry or ascent.
- a handle can run as a curved element between two spherical clamps.
- Decorative elements are very diverse. Among other things, they include cladding, but also ladders, climbing poles or other climbing and boarding aids in the scaffolding system. Elements for sun protection can also be held on the receptacles of the spherical clamps and can extend over areas of the scaffolding, for example as sun sails, so that the users are protected from direct sunlight.
- Ropes are other items that can be attached to a spherical clamp or run between spherical clamps. These can serve as fall protection, but also for climbing and playing.
- a closure plug should be understood as a molded part that closes the receptacle to the outside, so that no dirt and water can penetrate and no one can reach into the opening formed by a receptacle and injure themselves.
- the receptacles for add-on parts are arranged offset by 90° (degrees) along the equator surfaces.
- four recordings can be distributed along an equatorial surface, which are distributed evenly along the circular base.
- add-on parts can be used in four main directions from the spherical clamp and thus the post. If a hemisphere is formed with two elements, as described above by way of example, and these are of the same size, two receptacles would be formed for each element. With such a regular arrangement, loads that are introduced via attachments into the receptacles and thus the spherical clamp can be evenly distributed and absorbed.
- a further embodiment of the scaffolding system is that an attachment is designed with a profile in the area that is inserted into a receptacle of the spherical clamp, and the receptacles of the spherical clamp are designed with a corresponding profile in order to ensure a positive fit between the attachment and the receptacle (n) to realize.
- a profiling in the end area or bearing area of an add-on part is to be understood as meaning a separately formed outer shape of this area, which is designed and formed by a curve, a radius, projections and recesses, edges and the like in such a way that it has a corresponding surface profile in one Recording comes into engagement and thus twisting and / or slipping in the recording is prevented. It is preferably embossed so that the add-on part has a smaller cross-section in this area.
- the profiling can be a circumferential octagonal profiling of the add-on part in the area of the support in the ball clamp.
- a tube as an attachment:
- an octagonal contour is implemented in some areas, which can be formed using a radial jaw press, for example. This is all around the end of the pipe shaped like an embossed ring.
- the recordings in the elements of the spherical clamp each have elevations that correspond to the depressions of this exemplary octagonal profile. If the attachment is placed or inserted into the receptacle, the profiles in the end area of the attachment and those of the receptacle come into touching contact and thus form a form fit.
- the profiling of the add-on part is preferably not formed up to its end, but there remains a section without profiling. In this way, the attachment can be secured against being pulled out or slipping out of the receptacle, since the widening behind the profiled receptacle region also brings about a form fit in this direction.
- the form-fitting design in the receiving area of the spherical clamp can be used for all add-on parts.
- an element of a first hemisphere can be formed with a bulge in a peripheral region of the hemisphere which extends into the peripheral region of the adjacent element of the other hemisphere and the adjacent element of the other hemisphere a corresponding recess. Provision is therefore made for an element of one hemisphere to extend in its edge region, ie along the spherical contour, into the edge region of the other hemisphere and in particular the element located there, which has a corresponding recess for this purpose.
- This area can be a fulcrum for assembly, around which the element of the upper half of the sphere can be pivoted into its end position. Since the upper half of the sphere is formed with the same elements as the lower half, there will be another similar combination with bulge and recess in the opposite arrangement.
- the bulge on the bulge of one element can engage with the receptacle in the recess of the other element during assembly and thus provide additional support .
- This can be used in particular to secure the position, in particular until all the elements have been screwed together.
- the protuberance can be in the form of a nose or a pin-like elevation in the area of the bulge, for example.
- each to each other corresponding elevations and / or depressions may be formed in order to achieve a form fit between the halves of the sphere. This can also prevent a displacement of the spherical halves relative to each other or the elements during installation along the equatorial surfaces. In the event of screw connections failing, a certain degree of residual security can also be provided.
- elevations and/or depressions are formed on the bases of the hemispheres that form the equatorial surfaces, with an elevation on one element of one hemisphere being accompanied by a depression in the opposite element of the other hemisphere.
- the elevation and depression engage and thus form the form fit.
- the boreholes and screw holes for connecting the two halves of the sphere have proven to be particularly suitable for this configuration.
- an elevation can be formed in the area of the borehole in the direction of the other half of the sphere and a depression in the area of the screw hole in the other half of the sphere.
- recesses should be formed in the direction of the screw connections, starting from the surface of the spherical clamp. This is to be understood as meaning that in the area of an element in which a screw is to be inserted for connection to another element, a recess is formed in the sense of a depression in the direction of the screw hole, so that the screw head is sunk into it when screwing. It is therefore lower than the rest of the surface of the element, so that accidentally getting caught on the screw head can be avoided. In addition, the screw can be protected from unauthorized access.
- the elements for forming the hemispheres are designed as hollow bodies. They should therefore not be provided as solid solid bodies, but rather have cavities where it makes sense and is technically possible with regard to the loads to be expected.
- the cavities must there are no closed cavities, but rather they can also be designed to be open in one or more directions. With such a design of the elements, the weight can be reduced considerably, which in turn allows a more extensive and free design of playground installations and/or climbing scaffolds.
- the scaffolding system according to the invention should preferably be used in playground structures, playground elements and/or climbing frames.
- Playground structures and playground elements can also be summarized under the term playground installations.
- a variety of playground installations and/or climbing frames can be designed using inclined (and non-inclined) posts, the spherical brackets, and attachments that attach to the brackets or otherwise to the scaffolding system. By deviating from right-angled constructions, such playground installations and/or climbing frames appear more playful, more organic and stimulate the creativity of the users, ie the children. Locations, figures or objects can also be more easily and better replicated when not limited to a right-angle attachment or construction system.
- playground installations and/or climbing frames can be designed with posts and clamps without being limited to a right-angled system. It allows for the inclination of the posts, while spherical clamps can be used to compensate for the angle of inclination, so that horizontally aligned receptacles can be provided for attachments of all kinds. In this way, intermediate levels can be installed quickly and easily and are immediately aligned horizontally.
- a clamp can also be attached to a non-inclined post and thus provide an inclined equatorial plane.
- the spherical clamps can also be mounted on inclined posts with a different angle. Any combination is possible and expands the design freedom for the development of playground installations and/or climbing frames.

- the elements 30A, 30B have screw holes 34 and threaded bushings 36 into which screws can be inserted, by means of which the two elements 30A, 30B can be screwed together and with the elements 30A, 30B of the other hemisphere 30.
- Element 30B in FIG. 2 has elevations 54 in the region of its screw holes 34, which are arranged on the equatorial surface 32 to be formed.
- Element 30A in FIG. 1 has indentations 56 in the area of the threaded bushings 36 which face the equatorial surface 32 to be formed. Both elements 30A, 30B together form a hemisphere 30.1 and in the same combination a second hemisphere 30.2, as will be shown in the following figures.
- recesses 39 are formed in the direction of the screw connections, ie the screw holes 34, in which the screws are sunk.
- receptacles 40 are provided in each element 30A, 30B. They are arranged in a 90° grid relative to the base area of the hemispheres 30 to be formed. Each of the receptacles 40 has a profile 44 which corresponds to a profile on an attachment in order to bring about a form fit between the attachment and the element 30A, 30B of the ball clamp 25 .
- the receptacles 40 and thus also the profiles 44 are each formed in half in an element 30A, 30B.
- the profiling 44 represents a constriction in the receptacle 40.
- the profiling of the add-on parts should run as an octagonal circumferential ring around the add-on part (see also FIG. 5).
- the element 30B has a bulge 46 in its edge area ( Figure 2), which protrudes in the direction of the element 30A of the other sphere half and overlaps it there.
- the element 30A has a corresponding recess 50 into which this bulge 46 can extend. This means that the spherical halves 30.1 and 30.2 can no longer be displaced relative to one another.
- the relative position of the two elements 30A, 30B in the two spherical halves 30.1 and 30.2 arranged one above the other is further fixed because the bulge 46 is formed with a protuberance or lug 48 which engages in a receptacle 52 of the recess 50 when the elements 30A, 30B be assembled.
- each hemisphere 30.1, 30.2 has an equatorial surface 32.1 and 32.2, respectively, which extends over both elements 30A, 30B.
- the elements 30A, 30B of a hemisphere 30.1, 30.2 each continue the inclination by the angle a, so that a common plane is formed.
- the spherical halves 30.1 and 30.2 are arranged one above the other, they must (as shown in FIG. 3) be rotated by 180° in relation to one another so that the inclinations of the equatorial surfaces 32.1 and 32.2 allow flush contact with one another and the formation of the spherical shape of the clamp 25.
- the screw holes 34 and threaded bushings 36 already described are also in the correct relative position, as are the bulges 46 and recesses 50.
- FIG. 4a shows a post 20 which is inclined at an angle a, as illustrated in FIG. 4b.
- the angle a should be 5° (degrees), for example.
- the post 20 is formed as a tube with a round cross-section.
- elements 30A and 30B of the lower hemisphere 30.1 are to be attached. As can be seen from FIG. 4a, these are partially designed as hollow bodies in order to reduce weight. They also have different colors to distinguish them quickly and safely, making installation easier and faster.
- the elements 30A, 30B are brought individually to the post 20 until they enclose it in a ring and then screwed with screws 38 together.
- the screw holes 34 and threaded bushings 36 already described above are used for this purpose. This also creates a clamping effect of the lower half of the sphere 30.1 on the post 20.
- the equatorial surface 32 formed by the elements 30A, 30B is now the same as before due to the formation of the elements 30A, 30B explained, aligned horizontally.
- add-on parts 60 are placed in the receptacles 40 of the element 30A provided for them.
- a tube 60.1 each, which is intended to serve, for example, as a horizontal connection between two posts.
- the tubes 60.1 have profiles 42 in the form of an octagonal ring, which correspond to the profiles 44 of the receptacles 40.
- the end of the tubes 60.1 no longer has any profiling. Since the profiling 42 forms a narrowing of the cross section and the pipes 60.1 then again have a further cross section without profiling, they cannot be pulled out of the receptacles along their longitudinal axis.
- the profiles 42, 44 prevent the tubes 60.1 from twisting and slipping in the receptacles 40 and offer the possibility of pre-aligning attachments 60 until the element of the upper half of the sphere can be attached and fixed.
- the profiles 42, 44 shown here can be used in the same way for other add-on parts 60.
- FIG. 6a makes it clear that the element 30B of the upper half of the sphere 30.2 is attached with its bulge 46 to the recess 50 of the element 30A of the lower half of the sphere 30.1 and is rotated around this in the direction of the post 20 .
- the protuberance 48 also comes into engagement with the receptacle 52 .
- the tubes 60.1, or other attachments, are now fixed in their position.
- the upper element 30B and the lower element 30A are connected to one another by means of screws 38. Sealing plugs 60.2 or other add-on parts 60 can now be inserted into the receptacles 40 of the lower element 30B (FIG.
- FIGS. 9 to 11 The application of the spherical clamp 25 and the entire scaffolding system 10 according to the invention is shown in FIGS. 9 to 11 by way of example. The figures are described together and the differences are pointed out in particular. Reference numbers are only assigned to relevant elements and explained, but not each element is individually identified.
- All three figures 9 to 11 each show a playground installation with climbing and play elements, implemented with the scaffolding system 10.
- the posts 20 are mostly inclined.
- a plurality of spherical clamps 25 is arranged on the post 20, on which in turn add-on parts 60 of all kinds are used.
- sun sails 60.4 are inserted and fastened to two recordings of a clamp 25.
- Handles 60.3 are arranged between two clamps 25 and make it easier to get into the climbing frame.
- Tubes 60.1 connect clamps 25 horizontally to each other and are used to attach trim elements and decorative elements that cannot be attached to a clamp 25.
- Some clamps 25 are only used decoratively with plugs 60.2.
- clamps form 25 starting points for climbing aids 60.5 and ladders 60.6.
- Figure 11 also shows the connection of cables 60.7 to the spherical clamps 25.
