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 from two hemispheres, each with at least two elements that encompass the post.
• the equatorial surfaces of the hemispheres, formed by the at least two elements deviate from a plane at a right angle to the inclined post at the same angle as the post itself is inclined. This ensures that the equatorial surfaces are horizontally aligned.
• the hemispheres of the clamps have receptacles for inserting attachments.
• Playground installations and climbing frames are often assembled from modular components. This limits the design possibilities. They frequently necessitate a vertical and horizontal alignment of components such as posts and attached parts, resulting from the use of modular components and resulting in perpendicular alignment. Such an arrangement is perceived as less creative and stimulating for playing children, and also as lacking in organic feel, especially when the playground installations and climbing frames are intended to resemble familiar objects or figures, such as a pirate ship. If the arrangement of individual components is to deviate from the rectangular grid, custom solutions are usually required, which are complex and therefore expensive.
• a climbing system is shown with climbing elements that can be assembled from various system components. No additional components for creating a climbing landscape are included.
• components for playground installations and climbing frames could be designed more flexibly, and in particular, it would be possible to deviate from purely vertical and horizontal orientations without having to resort to individual custom solutions each time.
• solutions are sought that primarily allow the connection and fastening of individual components to each other at varying angles.
• the object of the invention is therefore seen as designing such nodes in such a way that A slanted arrangement of components is possible.
• the scaffolding system therefore consists of posts and spherical clamps, which are combined in the number required for the scaffolding or the specific application.
• a post is defined as a load-bearing component with a predominantly longitudinal dimension, oriented vertically or whose orientation is primarily vertical. At least one of these posts is inclined at an angle to the vertical.
• a post can be tubular or hollow.
• At least one spherical clamp is arranged on an inclined post.
• This spherical clamp is formed from two joined hemispheres, each of which is in turn composed of at least two elements. Within each hemisphere, the elements differ due to the inclination of the equatorial surface and, where applicable, the design of the screw connections or other optional features. As will be shown, the hemispheres are identical to each other. They consist of structurally identical elements. Each hemisphere forms an upper and a lower half and is arranged one above the other to form a sphere.
• hemispheres should not be understood as hemispheres in the geometrically correct sense. Rather, the groupings of at least two elements roughly correspond to a hemisphere. They thus have the appearance of a hemisphere, but deviate from a hemispherical shape in the geometric sense due to the inclined equatorial surface, which will be explained later. After the hemispheres are assembled, as will be explained below, the resulting spherical bell appears to be a sphere.
• each spherical hemisphere encompass the post. They are shaped and arranged in such a way that, when installed, they enclose the post. To this end, the elements of each spherical hemisphere have a section that corresponds to the outer contour of the post, so that the elements of the spherical hemispheres rest against the post in this area.
• each hemisphere each form an equatorial surface.
• this equatorial surface does not extend in a plane perpendicular to the inclined post. Instead, it deviates from the plane perpendicular to the post by the angle at which it is inclined. Thus, in the installed state, it is horizontally oriented and, within the manufacturing and assembly tolerances, essentially horizontal.
• the hemispheres are rotated relative to each other, so that the inclination of the equatorial surfaces of the two hemispheres results in the upper equatorial surface being flush with the surface.
• the lower equatorial surface is permitted.
• the attachment to the inclined post ensures that the equatorial surface is essentially horizontally aligned.
• each hemisphere is screwed together, i.e., connected by screws.
• a clamping effect is also achieved between the at least two elements of a hemisphere and the inclined post, thus preventing the spherical clamp from slipping along the inclined post.
• At least two screws are provided for the screw connections. These are screwed through corresponding screw holes in one of the at least two elements of a sphere half into corresponding threaded bushings in an adjacent element within the sphere half if the elements of a sphere half are to be screwed together.
• the screw holes are provided in at least one element of one sphere half and threaded bushings in the at least one element of the other sphere half that is adjacent to it when assembling the spherical clamp.
• the elements of the spherical hemispheres have recesses in the area of the equatorial surfaces into which at least one attachment can be inserted. These recesses are understood to be cutouts in the elements of the spherical hemispheres into which attachments or their ends can be inserted or arranged. Attachments are also elements of the frame system. The recesses are designed such that each half is arranged in an element of the lower spherical hemisphere and an adjacent element of the upper spherical hemisphere, with these half-recesses corresponding to each other in position and size. and, after assembly, enclose an inserted attachment or its end.
• the essential inventive feature of the scaffolding system according to the invention is that the elements of the two spherical hemispheres are identical.
• the upper and lower hemispheres are therefore the same.
• the inclination in the area of the equatorial surfaces, the screw holes and threaded bushings for screwing the spherical hemispheres together, and the receptacles for attachments are designed, arranged, and aligned in such a way that the spherical hemispheres can be easily assembled and connected to each other.
• Each half of the sphere in this example consists of one element A and one element B.
• element A and element B of the lower half are positioned on the inclined post and screwed together.
• attachments can be inserted or placed into the designated slots.
• element B of the upper half is placed onto element A of the lower half and screwed in place, followed by element A of the upper half being placed onto element B of the lower half.
• elements A and B of the upper half are screwed together, and element A of the upper half is screwed to element B of the lower half. It is recommended to insert only the attachment(s) into the designated slots and screw them in immediately to prevent them from falling out until the corresponding element of the upper half is mounted.
• the upper hemisphere is offset from the lower hemisphere, such that element B sits above element A and element A above element B.
• the scaffolding system can be formed with additional posts and spherical clamps, which can be arranged at different angles of inclination.
• the scaffolding system according to the invention therefore makes it possible to install inclined posts while always providing the connections for all types of attachments in a horizontal orientation.
• the inclined arrangement of posts allows playground installations and climbing frames to be designed in a more organic and pleasing way, offering greater design flexibility.
• the at least one post has a round cross-section, and the hemispheres of the at least one clamp arranged on it each encircle the post in a ring-like manner. If the post has a round cross-section, it has no edges or corners on which a user of the scaffolding system could bump into and injure themselves. This also results in a more aesthetically pleasing appearance.
• the spherical clamp which is arranged on such a round, inclined post, encircles it in a ring-like fashion.
• the elements of the hemispheres are formed on the surfaces facing the post, relative to a top view, with arc segments that, when assembled, form a circle corresponding to the diameter of the round post. In spatial terms, the inner surfaces form a cylinder through which the post passes.
• a post is arranged at an angle of 2° to 12°, particularly at a tilt of approximately 5°.
• An inclination of 2° to 12° is already perceived by the eye as a tilt and deviation from the vertical, allowing for more diverse designs of playground installations and climbing frames. Larger angles of inclination place higher demands on the stability and sturdiness of the scaffolding system.
• the at least two elements of a sphere hemisphere have different colors.
• the colors should preferably be easily recognizable.
• the different colors serve to identify each individual element. All elements of the same type are therefore the same color. Thanks to the different colors, it is easy and reliable to distinguish which elements are to be assembled and which element still needs to be added for complete assembly, without having to search for printed or embossed markings and/or measure the elements. Therefore, assembly can also be carried out using a simple color-coded image.
• the upper and lower halves of the sphere are colored the same, as the same elements are used in both halves.
• the scaffolding system can be equipped with various attachments, meaning it must include at least one attachment.
• An attachment can be selected from the following groups: tube, handle, decorative element, sunshade, rope, or end cap.
• An attachment can be fixed in place by means of a single receptacle in the spherical clamp, or by means of multiple receptacles in the same spherical clamp. Some attachments have only one attachment point on a clamp, while others are secured by multiple clamps.
• a tube as a longitudinally extended hollow body, can be used, for example, as a horizontal connection between two spherical clamps on two posts, especially inclined posts. It can thus form a fall protection barrier, but also provide a mounting option for cladding, decorations, and other attachments that are not designed for attachment to a spherical clamp.
• a tube can simply have a linear extension, i.e., be a straight tube, but it can also be used in curved shapes.
• a handle is an attachment designed to provide users of the scaffolding system with support or to facilitate entry or ascent.
• a handle can, for example, be a curved element running between two spherical clamps.
• Decorative elements are very diverse. They include, among other things, cladding, but also ladders, climbing poles, or other aids for accessing and entering the scaffolding system. Elements for sun protection can also be attached to the spherical clamps and, for example, extend as sun sails over sections of the scaffolding, thus protecting users from direct sunlight.
• Ropes are another element that can be attached to a spherical clamp or They can run between spherical clamps. These can serve both as fall protection, but also for climbing and playing.
• a plug is a molded part that seals the receptacle from the outside, preventing dirt and water from entering and also preventing anyone from reaching into the opening and injuring themselves.
• the mounting points for attachments are arranged at 90° intervals along the equatorial surfaces. In total, four mounting points can be distributed along one equatorial surface, evenly spaced along the circular base. This allows attachments to be inserted from the spherical clamp, and thus the post, in four main directions. If a hemisphere, as described above, is formed with two elements of equal size, each element would have two mounting points. This regular arrangement ensures that loads transferred via attachments into the mounting points, and thus into the spherical clamp, are evenly distributed and absorbed.
• a further embodiment of the scaffolding system consists in that it comprises at least one attachment part and that at least one attachment part is designed with a profile in the area which 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 achieve a positive fit between the attachment part and the receptacle(s).
• a profile in the end or support area of an attachment is understood to be a separately shaped outer form of this area, designed and formed by a curve, radius, projections and recesses, edges, and the like, in such a way that it engages with a corresponding surface profile in a receptacle, thus preventing rotation and/or slippage within the receptacle. It is preferably embossed, so that the attachment has a smaller cross-section in this area.
• Profiling the attachment and the corresponding profiling of the receptacle can also predefine the orientation of the attachment, which facilitates installation.
• the profile can be a circumferential octagonal profile of the attachment in the area where it rests in the ball clamp.
• a pipe as an attachment:
• an octagonal contour is formed in certain areas, for example, using a radial jaw press.
• This contour is formed circumferentially in the end region of the pipe, resembling an embossed ring.
• the recesses in the elements of the spherical clamp each have protrusions that correspond to the depressions of this exemplary octagonal profile.
• the profile of the attachment does not extend to its end, leaving an unprofiled section. This secures the attachment against being pulled or slipped out of the receptacle, as the widening behind the profiled receptacle also creates a positive fit in this direction.
• the form-fitting design in the receiving area of the spherical clamp can be used for all attachments.
• an element of the first sphere half can be designed with a bulge in an edge region of the sphere half that extends into the edge region of the adjacent element of the other sphere half, and the adjacent element of the other sphere half has a corresponding recess.
• an element of one sphere half extends in its edge region, i.e., along the sphere's contour, into the edge region of the other sphere half and, in particular, into the element located there, which has a corresponding recess for this purpose.
• This area can serve as a pivot point for assembly, around which the element of the upper sphere half can be pivoted into its final position. Since the upper sphere half is designed with the same elements as the lower one, there will be another, similar combination with a bulge and recess in a reversed arrangement.
• the bulge is also formed with a protrusion and the recess of the other element has a corresponding receptacle, during assembly the protrusion on the bulge of one element can engage with the receptacle in the recess of the other element, thus providing additional support.
• This can It serves primarily as a means of securing the assembly, especially until all elements are fully screwed together.
• the protrusion can, for example, take the form of a nose or a pin-like elevation in the area of the bulge.
• corresponding protrusions and/or depressions can be formed along the equatorial surfaces of the spherical hemispheres to create a positive fit between them. This also prevents displacement of the hemispheres relative to each other or of the elements during installation along the equatorial surfaces. In the event of screw connections failing, this can also provide a certain degree of residual safety.
• the base surfaces of the spherical hemispheres forming the equatorial surfaces are provided with raised areas and/or depressions, with a raised area on one element of the spherical hemisphere corresponding to a depression in the opposite element of the other hemisphere.
• the raised area and depression engage, thus forming a positive fit.
• the drill holes and screw holes for connecting the two spherical halves prove particularly suitable for this design.
• a raised area can be formed in the area of the drill hole facing the other spherical half, and a recess in the area of the screw hole in the other spherical half.
• recesses should be formed on the surface of the spherical clamp, extending towards the screw holes. This means that in the area of an element where a screw is to be inserted to connect it to another element, a recess is formed, similar to a depression, extending towards the screw hole, so that the screw head is countersunk when tightened. It is thus recessed below the rest of the element's surface, preventing accidental snagging on the screw head. This also protects the screw from unauthorized access.
• a further embodiment of the scaffolding system according to the invention provides that the elements forming the hemispheres are designed as hollow bodies. They are therefore not to be provided as solid, solid bodies, but rather have cavities where this is practical and technically feasible with regard to the expected loads. These cavities need not be closed; they can also be open in one or more directions. Such a design of the elements allows for a significant reduction in weight, which in turn permits a more expansive and flexible design of playground installations and/or climbing frames.

• Playground structures and playground elements can also be collectively referred to as playground installations.
• a variety of playground installations and/or climbing frames can be designed using inclined (and non-inclined) posts, spherical clamps, and attachments that are connected to the clamps or otherwise to the scaffolding system.

• places, figures, or objects can be replicated more easily and effectively when there is no restriction to a rectangular fastening or construction system.
• the scaffolding system according to the invention offers a solution for designing playground installations and/or climbing frames with posts and clamps without being limited to a rectangular system. It allows for the tilting of the posts, while spherical clamps compensate for the angle of inclination, thus providing horizontally aligned mounting points for attachments of all kinds. This enables the quick and easy installation of intermediate levels, ensuring they are immediately horizontally aligned. Naturally, such a clamp can also be attached to a non-tilted post, thereby providing a tilted equatorial surface. The spherical clamps can also be mounted on tilted posts at different angles. Any combination is possible, expanding the design possibilities for the development of playground installations and/or climbing frames.

• the profiles 42, 44 prevent the tubes 60.1 from twisting and slipping in the receptacles 40 and allow for the pre-alignment of attachments 60 until the element of the upper spherical hemisphere can be attached and fixed.
• the profiles 42, 44 shown here can be applied in the same way to other attachments 60.
• FIG. 9 Each illustration shows a playground installation with climbing and play elements implemented using the scaffolding system 10.
• the posts 20 are mostly inclined.
• a large number of spherical clamps 25 are arranged on the posts 20, to which various attachments 60 are inserted.
• Sunshades 60.4 are inserted and attached to two mounting points of a clamp 25.
• Handles 60.3 are positioned between two clamps 25 and facilitate access to the climbing frame.
• Tubes 60.1 connect clamps 25 horizontally and serve to attach cladding elements and decorative elements that cannot be attached to a clamp 25.
• Some clamps 25 are also used purely for decorative purposes with plugs 60.2.
