Cross oscillator

from Wikipedia, the free encyclopedia
Kreuzschwinger (2nd generation)

The Kreuzschwinger is a piece of seating furniture and is one of the design classics. It was developed by Till Behrens in the 1950s . The chair was further developed in the following years and an extensive range of furniture was designed. In 2004 a new generation with modified design features came onto the market. Till Behrens Systeme GmbH produced the cross-oscillators under license until 2017. Production was discontinued in 2017 with the opening of insolvency proceedings over the assets of Till Behrens Systeme GmbH.

function

Kreuzschwinger is seating and reclining furniture, the seats and backrests of which can swing back and forth and automatically adapt to any change in posture. Depending on the load shift, the seat surfaces lower at the front or back and take the backrests with them.

Functionally, constructively and in terms of their appearance, cross-swings do not belong to the cantilever family . Kreuzschwinger not only swing by name, but actually swing evenly forwards and backwards without mechanics. Despite their name, cantilever chairs cannot swing, but only rock backwards, as they are rigid on one side, usually at the front.

Dynamic sitting

With the Kreuzschwingern, it was possible to achieve the dynamic sitting required by orthopedists without mechanics. “The Kreuzschwinger is medically / ergonomically developed with people in mind. It adapts to the sitting posture and guarantees safety with the central cross. The Kreuzschwinger does not force you to take a static but a dynamic sitting posture, ”says the orthopedist and former medical supervisor of the German national soccer team, Hannes Schoberth .

layout

Kreuzschwinger has won many national and international design awards as an "icon of modern sitting" ( Lentos Art Museum Linz ) and has been accepted into numerous national and international museums and galleries. There are two generations of Kreuzschwinger. The first generation has parallel runners and a counter arm. The second generation has crossed runners and no counter-arm. The second generation is even more dematerialized than the first, vibrates more softly and visually shows the flexibility and high compressive and tensile strength of steel more clearly. With almost the same overall appearance and function of the two generations, they have different power courses.

Plagiarism failed because of international property rights

Kreuzschwinger have the highest international art and technology property rights. Your name is also protected as an international word mark . They had different manufacturers and were plagiarized over 100 times until they were judged to be granted extensive copyright protection for “applied arts”. This makes the Kreuzschwinger the ninth piece of seating furniture in the history of product design to be granted this protection. The history of plagiarism is described in detail in the book Kreuzschwinger - Dynamisches Sitzen (Ed. Aktion Plagiarius) and is described by Bettina Rudhof in the db deutsche bauzeitung as "exciting as a crime thriller".

Trivia

For the opening of the exhibition Flexible Crosses in the Museum of Applied Arts Frankfurt , three sound compositions for playing on cross-swing chairs were premiered on September 26, 2008:

Valentin Haller describes that the “basic idea of ​​the composition” lies in the

“[...] juxtaposing the sounds of the cross oscillator with those of an acoustic instrument. The types of violin used, arco, pizzicato and battuto, for example, also apply to the previously recorded sounds of the cross-oscillator. From the physical conditions of the two instruments, there is an approximation through the way they are played. The chair also provides the sound material that is taken over by the violin, which stimulates a further comparison: The sounds of the cross-oscillator are reproduced by four loudspeakers in a rectangular arrangement. According to the movements of the 2nd generation Kreuzschwinger, these sounds no longer behave along the sides, but rather diagonally. The loudspeakers also serve as a medium for the violin, whose electronic deformation, in contrast, moves strictly along the edges, i.e. in a circle. The severity of these types of movement was the inspiration for the title of the piece. There are also formal processes that move back and forth, to a certain extent an abstraction of the two types of movement. Ultimately, they also find a common denominator. "
