Abstract

The staircase (1) has two beams (2) made from metal-plate material. The beams are supported by threaded bolts (3) that are connected with the beams by an arc welding. The threaded bolts are provided for detachably fastening of components to the beams. The threaded bolts arranged on an inner side of the beams accommodate a supporting bracket by lateral recesses. Staircase steps are detachably fixed in a variable position by wooden screws and made from massive hardwood. The staircase steps are designed as bent parts made from metal sheet with lateral support surfaces.

Description

Die Erfindung betrifft eine Treppe nach dem Oberbegriff des Anspruchs 1.The invention relates to a staircase according to the preamble of claim 1.

Stand der TechnikState of the art

Treppen für den Einsatz in Innenräumen oder im Freien werden aus verschiedenen Werkstoffen hergestellt, bestehen aber oft aus korrosionsarmem oder gegen Korrosion geschütztem Metall. Sie werden zumeist als Einzelstücke von Handwerkern angefertigt. Parallel dazu werden jedoch auch Bausätze für solche Treppen angeboten, die von Endverbrauchern wie technisch versierten Heimwerkern selbst installiert werden können. Wie zum Beispiel in der DE202011002694 sowie DE202005014709 gezeigt, besitzen derartige Treppen oft Wangen, die aus einer Vielzahl einzelner Elemente zusammengeschraubt werden. In der DE69505261 sind einstückige Wangen vorgesehen, die aus einem Profil bestehen und mit darauf verschiebbaren Befestigungsmitteln zusammenwirken. Während die handwerklich gefertigten Treppen sehr teuer sind, stellen die Treppen-Bausätze auch nur unbefriedigende Alternativen dar. Sie sind nur unwesentlich preisgünstiger, weisen aber konstruktionsbedingt große Defizite hinsichtlich Stabilität und, vor allem, ästhetischer Qualität auf.Stairs for indoor or outdoor use are made of a variety of materials, but often consist of low-corrosion or corrosion-protected metal. They are usually made as individual pieces by craftsmen. In parallel, however, kits are also available for such stairs, which can be installed by end users such as tech-savvy DIYers themselves. Like in the DE202011002694 such as DE202005014709 shown, such stairs often have cheeks, which are screwed together from a variety of individual elements. In the DE69505261 are integral cheeks provided, which consist of a profile and cooperate with sliding fasteners thereon. While the hand-crafted stairs are very expensive, the stair kits are also unsatisfactory alternatives. They are only marginally cheaper, but design-wise have large deficits in terms of stability and, above all, aesthetic quality.

Aufgabenstellungtask

Im Hinblick auf den zuvor beschriebenen Stand der Technik besteht die Aufgabe darin, durch die intelligente Kombination von preisgünstigem Halbzeug und rationellen Fertigungsverfahren eine ergonomisch gute Treppe zu schaffen, die sich kostengünstig serienmäßig herstellen lässt und auch höheren gestalterischen Ansprüchen gerecht wird.With regard to the prior art described above, the task is to create an ergonomically good staircase by the intelligent combination of low-priced semi-finished and rational manufacturing processes, which can be mass-produced in a cost-effective manner and also meets higher design requirements.

Erfindunginvention

Die Erfindung betrifft eine Treppe vorwiegend aus Metall, die in Form von vorgefertigten Einzelteilen bzw. Halbzeugen geliefert werden kann. Sie besteht aus zwei Holmen, die als Rechteckrohr oder Plattenmaterial ausgeführt sein können, besitzt Stufen aus abgekantetem Blech oder optional massivem Material, Geländerstützen aus abgekantetem Blech oder optional Winkelprofil, Handläufen aus Rundrohr sowie verspannbaren Stahlseilen oder auch anderen Mitteln zur Abschrankung. Die Einzelteile werden mittels Gewindestiften, die vorzugsweise durch Lichtbogenschweißen mit den tragenden Holmen verbunden sind, sowie entsprechenden Muttern aus nichtrostendem Material miteinander verschraubt. Der wesentliche Vorteil der Erfindung gegenüber dem Stand der Technik besteht darin, dass die Treppe rationell und deshalb kostengünstig vorgefertigt werden kann und trotz des modularen Aufbaus und der geometrischen Variabilität, die eine Anpassung an unterschiedliche Gegebenheiten erlaubt, ein ästhetisch ausgewogenes, geschlossenes Ganzes bildet.The invention relates to a staircase mainly of metal, which can be supplied in the form of prefabricated items or semi-finished products. It consists of two spars, which can be designed as a rectangular tube or plate material, has steps made of bent sheet metal or optional solid material, railing supports made of bent sheet metal or optional angle profile, handrails made of round tube and bracing steel cables or other means of protection. The items are by means of threaded pins, which are preferably connected by arc welding to the supporting bars, and corresponding nuts made of stainless material screwed together. The main advantage of the invention over the prior art is that the stairs can be prefabricated rationally and therefore inexpensively, and despite the modular structure and the geometric variability, which allows an adaptation to different circumstances, forms an aesthetically balanced, closed whole.

Ausführungsbeispieleembodiments

Nachstehend ist die Erfindung anhand der beigefügten Zeichnungen, die Ausführungsbeispiele darstellen, näher erläutert. Es zeigt:The invention is explained in more detail below with reference to the accompanying drawings, which illustrate exemplary embodiments. It shows:

An diesen werden mittels handelsüblicher Schrauben und Muttern sowohl die Geländerstützen (4) als auch die Stufen aus abgekantetem Blech (6) befestigt. Die Geländerstützen (4) besitzen Bohrungen, um handelsübliche Abschrankungs-Stahlseile (7) durchzuführen und zu verspannen und sie tragen auch die Handläufe (5). Mittels Winkeln (8) werden die Holme winkel- und positionsvariabel mit Gebäudeteilen bzw. Auflagefundamenten verschraubt.The stairs ( 1 ) has two spars made of metal ( 2 ), the butt, preferably in the arc process, welded threaded bolt ( 3 ) wear. At these by means of commercial screws and nuts both the rail supports ( 4 ) as well as the steps of bent sheet metal ( 6 ) attached. The rail supports ( 4 ) have bores to commercially available safety steel cables ( 7 ) and they also carry the handrails ( 5 ). By means of angles ( 8th ) the spars are screwed angle and position variable with building parts or support foundations.

2 eine Detailansicht der erfindungsgemäße Treppe mit Stufen aus massivem Material schräg von oben. Zur besseren Anschaulichkeit sind die beiden unteren Stufen unsichtbar. Ebenso sind die Geländerstütze mit Abschrankungs-Stahlseilen sowie ein Befestigungswinkel aus der normalen Lage verschoben. 2 a detailed view of the staircase according to the invention with steps of solid material obliquely from above. For better clarity, the two lower levels are invisible. Likewise, the railing support are shifted with safety steel cables and a mounting bracket from the normal position.

Die Holme (2) tragen Gewindebolzen (3, 3'), welche sowohl zur Befestigung der Treppe selbst als auch zur Anbringung von Auflagewinkeln (9) für massive Stufen (12) und von Geländerstützen (4) dienen. Um die Anpassung an örtliche Gegebenheiten zu ermöglichen, besitzen die Auflagewinkel (9) wie auch die Geländerstützen (4) jeweils zwei Durchbrüche, davon mindestens jeweils einen Durchbruch in Langlochform (10, 10'). Abschrankungs-Stahlseile (7) werden vorzugsweise mittels Hutmuttern (11) an der jeweils untersten und obersten Geländerstütze (4) befestigt.The spars ( 2 ) carry threaded bolts ( 3 . 3 ' ), which are used both for fastening the staircase itself and for attaching supporting angles ( 9 ) for massive steps ( 12 ) and railing supports ( 4 ) serve. To allow adaptation to local conditions, the support angles ( 9 ) as well as the rail supports ( 4 ) two breakthroughs, of which at least one breakthrough each in slot form ( 10 . 10 ' ). Safety steel cables ( 7 ) are preferably by means of cap nuts ( 11 ) at the respectively lowest and upper railing support ( 4 ) attached.
