Abstract

platform construction for universal use (attachment) to variable mounting bodies telescopic fastening device.

Description

A n-shaped star-shaped Console with radial, concentric mounting option of static structures (benches, Platforms, tables, tree houses) on any solids round or polygonal cross section (trees, trunks, masts, pipes) if possible low contact pressure. Intended use z. B. as a "platform" in adventure parks and high ropes climbing facilities. The choice of material depends on the Overall design. The materials that can be used in the construction can They vary (wood, metal and plastic) and in combination be used together, depending on which static and / or aesthetic concerns Fulfills should be.

1. State of the art

So far The platforms will be opposite each other by means of 2 × 2 Wooden round or angular cross-section, with a diameter / edge length between 10-20 cm, with the two directly superimposed clamping levels um 90 ° against each other rotated, and bolted together. In each case a pair of these facing each other in parallel woods will over two across the core Holes with two threaded rods of 16-20 mm diameter under high pressure pressed against the tree. Depending on the tree size are then between 10-15% of Trunk circumference affected. This results in the risk of cambial damage, the result of a disruption of water and assimilate transport in the respective load level leads. A dying of the tree, as this is not sufficient with nutrients can be supplied, is then the possible consequence. This effect occurs all the more on if multiple platforms on a trunk in different Layers on top of each other to be built in.

A Reduction of pressure with large, Lastverteilenden layers (neoprene plates) carries the risk of Fungus (bark necrosis), as between the bark of the tree and This load distribution layer a favorable climate for this Mushrooms is created. These in turn can the tree in another, additional Harm the way. The tightening torque of the threaded rod / nut combination is at z. Z. two crushing levels, about 70 Nm. The resulting Pressure on the tree trunk amounts about 9 KN. A reduction of the contact pressure is only by a increase the number of contact points possible, or by the installation of relatively large area, pressure distributing Plains with the risk of fungal attack.

In addition, can Fastening of a substructure only at a right angle to Stem. Thus, the platform is often "wrong." The platforms must be in this process with be adapted to high time and cost individually. So far can Platforms are not uniform, standardized, prefabricated.

2nd task

2.1 Development and construction of a versatile console (platform), different from the previous one Manufacturing practice in the sense of a significant technical improvement different.

• 1. Erhöhung der Anzahl der Anpresspunkte am Befestigungskörper, bei gleichzeitiger Reduktion des Anpressdruckes an jedem einzelnen Punkt (z. B. Baum) in mehreren Ebenen, aber innerhalb einer schlanken Bauform, d. h. innerhalb der jetzigen Bauhöhe von ca. 35 cm

2.2 solutions the task

• 1. Star-shaped, on a common center (tree axis) facing arrangement of upright standing Spokes. Drill holes in the inner face of the boards (to the tree indicative) for receiving telescoping and lockable devices in the number of at least 3n. Due to the high number of contact points The contact pressure is reduced at each individual contact point. The devices become the tree with small area, doorstop similar Neoprene rubber pad, which provides compression of up to 80% volume, without experiencing permanent deformation.
• 2. The telescopic devices can not be only remove the contours but also the inclinations of the fastening body (to 12 °).
• 3. Coupling and adaptation of the prefabricated universal console to the fastening body is done by telescoping and lockable devices.
• 4. The telescoping and lockable devices are fast and easy to guide by hand to the mounting body and determine. The defined torque is verified by means of a torque wrench.
• 5. The console is freely accessible from below and above. The telescoping and lockable devices remain constantly adjustable.
• 6. strapping all open joints through the secondary frame, the dull edges with big ones Has radii. This is threading effectively prevented. abrasions, as possible on open board ends are greatly reduced by the blunt edges.

Construction description of the console

• 1. „Hohlnabe" = Primärer Rahmen der Konsole
• 2. „Speichen" = Speichen der Konsole
• 3. „Felge" = Sekundärer Rahmen der Konsole

The console is structurally composed of three different, each n-fold components and forms in plan view the shape of an equilateral n-corner. The structure is similar to the elements of a wheel with:

• 1. "hollow hub" = primary frame of the console
• 2. "spokes" = spokes of the console
• 3. "rim" = secondary frame of the console

Used assemblies:

• 1. Primärer Rahmen: Die Konstruktion des primären Rahmens (Anlage 02) ist n-eckig, gleichseitig, mit n-fach vorhandenen Bauteilen. Diese sind mit je einem linken und rechten Gehrungsschnitt mit dem Winkel 360°/2n versehen. In den Flächen des Gehrungsschnittes werden Schwalbenschwanznuten eingebracht. Die zusammengesetzten Bauteile ergeben die Hohlnabe der Konsole, in der dann bei der Montage, axial konzentrisch, der Befestigungskörper zu liegen kommt.
• 2. Speichen: Speichen (Anlage 04) in der Anzahl n. Die Speichen werden im Bereich des primären Rahmens beidseitig mit Schwalbenschwanznuten versehen.
• 3. Sekundärer Rahmen: Die Konstruktion des sekundären Rahmens (Anlage 02, Anlage 03) ist n-eckig, gleichseitig, mit n-fach vorhandenen Bauteilen. Diese sind mit je einem linken und rechten Gehrungsschnitt mit dem Winkel 360°/2n versehen. In den Flächen des Gehrungsschnittes werden Schwalbenschwanznuten eingebracht. Die zusammengesetzten Bauteile ergeben die „Felge" der Konsole.

The design description is from the inside to the outside, from the primary to the secondary components.

• 1. Primary frame: The construction of the primary frame (Appendix 02) is n-sided, equilateral, with n-fold components. These are each provided with a left and right miter cut with the angle 360 ° / 2n. In the areas of the miter cut dovetail grooves are introduced. The composite components yield the hollow hub of the console, in which then during assembly, axially concentric, the mounting body comes to rest.
• 2. Spokes: spokes (Appendix 04) in the number n. The spokes are provided on both sides with dovetail grooves in the area of the primary frame.
• 3. Secondary frame: The construction of the secondary frame (Appendix 02, Appendix 03) is n-sided, equilateral, with n-fold components. These are each provided with a left and right miter cut with the angle 360 ° / 2n. In the areas of the miter cut dovetail grooves are introduced. The assembled components give the "rim" of the console.

Primary and secondary, n-fold existing frame parts are dowelled and dovetail Assembly adhesive joined together to form an equilateral n-sided frame.

The n-fold spokes connect the primary to the secondary frame, each in the area of the directly opposite corners of the Frame.

Of the secondary Frame comes axially, concentrically and form-fitting in a "claw" of the spokes Lie and is secured with a screw against lifting. The Pierced spokes the primary Frame inwards and protrude into its interior. These can ever shortened as needed be and enable thus the adaptation to mounting body with different shapes and diameters.

Primary and secondary Frame, as well as spokes, adjust each other mutually.

Primary and secondary Frame as well as the spokes form a constructive, developable, two-dimensional Plane for receiving a surface-filling, load-bearing level (Appendix 01) within the entire secondary framework out. This level may consist of adjacent boards, full-surface boards, Gratings or any other materials exist. She poses the usable area the console. On this surface comes the payload to stand and / or to lie. In the area of primary Frame, this level can be provided with an opening. By this protrudes axially, concentrically the fastening body.

The Coupling of the console to the mounting body via telescoping, regulatable and detectable devices operating within the spatial Structure of the spokes are introduced. These are bores within the spoke as a receptacle and guide for these devices.

4.0 Innovations

• 1. Die Konstruktion der Konsole ermöglicht eine deutliche Erhöhung der Anzahl der Anpresspunkte am Befestigungskörper. Daraus ergibt sich ein reduzierter Anpressdruck am einzelnen Anpresspunkt. Bei Anbringung an lebenden Bäumen stellt dieses eine substanzielle und nachhaltige Verbesserung des Baumschutzes dar. (Forderung von DIN EN Norm 15567 Teil 1 und Teil 2, zum Bau und Betrieb von Seilgärten)
• 2. Aus der Verwendung von identischen Gleichbauteilen (Reduzierung der Bauteile) ergibt sich für die Herstellung der Bauteile für die Plattform eine vereinfachte Qualitätssicherung. Dies ist auch relevant für die Haftungsfrage bezogen auf Hersteller, Monteure und anderweitig daran beteiligter Personen und Gruppen. Eine Zertifizierung als Baumuster wird durch die standardisierte Bauweise möglich.
• 3. Durch die einfache Handhabung lässt sich die Konstruktion sehr leicht und schnell einbauen. Eine sichere Montage ist somit auch Autodidakten möglich.
• 4. Durch die kompakte, in sich geschlossene Form findet eine Reduzierung der möglichen Unfallquellen statt. Das Einfädeln von z. B. Kordeln, Reißverschlüssen, Körperschmuck, Halsketten, Seilen, Gliedmaßen etc. in die Brettfugen an den Stirnseiten ist nicht mehr möglich. Weiterhin ist, durch die geschlossene Bauform mit stumpfen Kanten des äußeren Rahmens, die Gefahr von Abschürfungen, besonders an den Schienbeinen der Klettergäste, deutlich reduziert.

With reference to 2.1, the following innovation is compared to current practice:

• 1. The construction of the console allows a significant increase in the number of contact points on the mounting body. This results in a reduced contact pressure at the individual contact point. When mounted on living trees, this represents a substantial and sustainable improvement of the tree protection. (Requirement of DIN EN Norm 15567 part 1 and part 2, for the construction and operation of ropes courses)
• 2. The use of identical equivalent components (reduction of components) results in a simplified quality assurance for the production of the components for the platform. This is also relevant to the liability issue related to manufacturers, fitters and other persons and groups involved. A certification as a model is possible by the standardized construction.
• 3. The ease of use makes the construction very easy and quick to install. A secure installation is thus possible even self-taught.
• 4. The compact, self-contained form reduces the potential sources of accidents. The threading of z. As cords, zippers, body jewelry, necklaces, ropes, limbs, etc. in the board joints on the front pages is no longer possible. Furthermore, by the closed design with blunt edges of the outer frame, the risk of abrasions, especially on the shins of climbers, significantly reduced.
