Abstract

The invention relates to seats of different kinds, the position of which can be changed, while maintaining a high degree of comfort and without the use of complicated and/or difficult devices. The seat, which is held on the supports by lateral hinges, is turned by means of small weight transfers caused by the body movements of the person seated thereon. During this process, the static balance positions change, as do the functions. It is even possible to swing back and forth. As the seat remains stable in the differen analogous positions, which are determined by the weight of the body, the seated person can, for example, drink or undisturbed rest. The seat can also be made to swing, in the manner of a hanging swing. Simple locking device can be used to stop rotation.

Sitze allgemein mit Scharnieren in Waage gehalten.Seats generally balanced with hinges.
Technischer BereichTechnical part
Die hier vorliegende Erfindung bietet den verschiedensten Sitzmoebein die Moeglichkeit der Rotation, indem Position und Funktion variiert werden koennen. Sie besteht grundsaetzlich aus zwei Teilen: die Stuetzen, die den Sitz halten und der Sitz selbst, der mit Scharnieren an den Stuetzen gehalten wird.The present invention offers a wide variety of seats the possibility of rotation, in that position and function can be varied. It basically consists of two parts: the supports that hold the seat and the seat itself that is hinged to the supports.

Im allgemeinen benoetigen Sitzmoebel, um die Position aendern zu koennen, besondere Vorrichtungen, die oft kompliziert und muehsam zu handhaben sind. Die hier vorliegende Erfindung dagegen ermoeglicht es schon nur mit einfachen Scharnieren und der Gewichtsverlagerung durch Koerperbewegungen desIn general, in order to change the position, seating furniture requires special devices that are often complicated and laborious to use. The present invention, on the other hand, makes it possible only with simple hinges and the shifting of weight through body movements
Benuetzers, der dabei aber sitzen bleibt. Der aktuelle Stand der Technik umfasst auf diesem Gebiet verschiedene Arten von Sitzen, die sich am ehesten an die hier vorliegende Erfindung annaehern, in Form von Schaukelsitzen, die an horizontalen Stangen oder unabhaengigen Halterungen wie Zimmerdecken, Balken und Baeumen aufgehaengt sind. Der Querbalken (Drehachse) muss in einer solchen Hoehe angebracht werden, dass der Benuetzer sich ohne Behinderung setzen kann. Deshalb haben diese Schaukelsitze im Grunde nur eine Position im statischen Gleichgewicht, und der Rotationswinkel erstreckt sich auf einem begrenzten Sektor. Vorstellung der ErfindungUser, who remains seated. The current state of the art in this field includes various types of seats which most closely approximate the present invention, in the form of swing seats, which are suspended from horizontal bars or independent supports such as ceilings, beams and trees. The crossbeam (axis of rotation) must be installed at such a height that the user can sit down without hindrance. Therefore, these swing seats basically have only one position in static equilibrium, and the angle of rotation extends over a limited sector. Presentation of the invention
Die Stuetzen bilden die Bodenauflage der Struktur; diese koennen getrennt und unabhaengig oder verbunden sein. Der Sitz wird seitlich mit Scharnieren an den Stuetzen gehalten; seine Drehung erfolgt axial auf der Verbindungslinie der Scharniere. Die Position der Scharniere ist ausgeglichen bezueglich des Eigengewichts des Sitzes und des Koerpergewichts des Benuetzers; so ergibt sich ein beachtlich grosser Rotationswinkel des Sitzes mit unendlich vielen Positionen des statischen Gleichgewichts, die durch geringfuegige Gewichtsverlagerungen, hervorgerufen durch Koerperbewegungen des sitzenden Benuetzers, bestimmt werden koennen"Fig 13, Fig 14, Fig 15, Fig 16". Mit einer entsprechenden Struktur kann sich der Sitz auch nur auf einer einzigen seitlich angebrachten Stuetze drehen, oder, an Stangen aufgehaengt werden, denn so bieten sich zwei verschiedene Rotationen: die charakteristische dieser vorliegenden Erfindung und jene der herkoemmlichen Schaukelsitze. Es besteht die Moeglichkeit, wenn man will, mit Hilfe von geeigneten einfachen Blockierungen den Rotationswinkel zu begrenzen, oder, um den Sitz festzustellen, und, ihn auch in ein Bett umwandeln zu koennen. Die Begrenzung des Rotationswinkels ist nuetzlich bei Anwesenheit von Kindern, die, wenn sie auf die Sitzflaeche hinaufsteigen, unangenehme Unfaelle riskieren wuerden. Dagegen ist die moegliche grosse Rotation wohltuend fuer den Kreislauf, die Wirbelsaeule und Personen, die viel Zeit stehend oder sitzend verbringen. Ausser diesem rein koerperlichen Aspekt ist auch jener, nicht weniger interessante, psychologische zu beachten: da die Sitzflaeche in den verschiedenen analogen, vom Koerpergewicht vorgegebenen, Positionen stabil bleibt, ergibt sich, dass der Sitz in einfacher Weise zum Schaukeln gebracht werden kann und verleiht infolgedessen einen angenehm spielerischen Entspannungseffekt.The supports form the base of the structure; these can be separate and independent or connected. The seat is hinged to the side of the supports; its rotation occurs axially on the connecting line of the hinges. The position of the hinges is balanced with respect to the weight of the seat and the body weight of the user; this results in a remarkably large rotation angle of the seat with an infinite number of positions of the static equilibrium, which can be determined by slight weight shifts, caused by body movements of the seated user "Fig. 13, Fig. 14, Fig. 15, Fig. 16". With a corresponding structure, the seat can also rotate on a single side-mounted support or be hung on rods, because this offers two different rotations: the characteristic of this invention and that of the conventional swing seats. It is possible, if you want, to limit the angle of rotation with the help of suitable simple blockages, or to determine the seat and to convert it into a bed. Limiting the angle of rotation is useful in the presence of children, who would risk unpleasant accidents if they climbed onto the seat. In contrast, the possible large rotation is beneficial for the circulation, the spine and people who spend a lot of time standing or sitting. In addition to this purely physical aspect, there is also the psychological one, which is no less interesting: since the seating area remains stable in the various analog positions determined by the body weight, the result is that the seat can be rocked in a simple manner and, as a result, confers a pleasantly playful relaxation effect.
Beschreibung der SkizzenDescription of the sketches
Die Eigenschaften der Erfindung werden in Bezug auf zwei Ausfuehrungsmoeglichkeiten besser hervortreten; diese stellen aber nur eines von vielen Beispielen dar. Im ersten gegebenen Entwurfbeispiel sind die Stuetzen getrennt und unabhaengig; diese werden von je zwei schraegen Streben gebildet und sind in ein hohles Prisma eingeklemmt, worauf sich ein Teil des Scharniers befindet. Der Sitz mit der Fussstuetze "Fig 1(1)" besteht aus einem flachen Rahmen, der aus vertikalen Streben der gleichen Staerke wie die der Stuetzen und Querstreben in Form zweier Rohre zusammengesetzt ist. Letztere sind in den Umschlag eines Stoffes eingefaedelt und bilden so die Sitzflaeche und die Rueckenlehne. In einem ausgeglichenen Punkt auf den vertikalen Streben ist der andere Teil des Scharniers befestigt "Fig 2(1)". Aus den Skizzen kann man weiters entnehmen: den, durch diese Struktur moegliche, beachtlich grosse Rotationswinkel "Fig 3, Fig 4, Fig 5, Fig 13, Fig 14, Fig 15, Fig 16"; die geeigneten Bolzen füer dieThe features of the invention will appear more clearly in relation to two possible embodiments; however, these are only one of many examples. In the first design example given, the supports are separate and independent; these are each formed by two oblique struts and are clamped into a hollow prism, on which part of the hinge is located. The seat with the footrest "Fig 1 (1)" consists of a flat frame, which is composed of vertical struts of the same thickness as that of the supports and cross struts in the form of two tubes. The latter are threaded into the cover of a fabric and thus form the seat and the backrest. At a balanced point on the vertical struts, the other part of the hinge is attached "Fig 2 (1)". From the sketches one can also see: the considerably large angle of rotation possible with this structure "Fig. 3, Fig. 4, Fig. 5, Fig. 13, Fig. 14, Fig. 15, Fig. 16"; the suitable bolts for the
Begrenzung des Rotationswinkels "Fig 2(2)", oder die Feststellung des Sitzes, um ihn in ein Bett umzuwandeln, und dabei die Breite des Sitzes als Bettlaenge auszunuetzen "Fig 4". Im zweiten Entwurfbeispiel wird eine, im Gegensatz zur vorhergehenden, weniger essentielle Struktur in der Art der traditionellen Diwane vorgeschlagen. In diesemLimitation of the angle of rotation "Fig 2 (2)", or the determination of the seat in order to convert it into a bed, thereby utilizing the width of the seat as a bed length "Fig 4". The second design example suggests a structure that is less essential than the previous one, in the manner of traditional divans. In this
Fall ist die Sitzflaeche von der Rueckenlehne getrennt, und die Stuetzen sind verbunden, indem sie ein einziges Stueck bilden"Fig 6, Fig 7, Fig 8, Fig 9"; am hoechsten Punkt der Stuetzen sind ein Teil des Scharniers und die Bolzen fuer die Begrenzung des Rotationswinkels befestigt "Fig 10(1)". Der andere Teil des Scharniers besteht hier aus "Oesen" "Fig 11(1)", die der Sitzflaeche und der Rueckenlehne das Drehen bis zur Bildung eines Bettes ermoeglichen "Fig 12". Diese Drehung ist stufenfoermig regulierbar mit einem Drehgriff "Fig 11(2)", der ein Zahnrad innerhalb einer gezahnten "Oese" betaetigt "Fig 11(3)" und, auf der gegenueberliegenden Seite, mit einem Bolzen "Fig 11(4)" und den dazugehoerigen anderen Teilen "Fig 11 (5)" füer die Feststellung der verschiedenen Grade der Rotation.In this case, the seat is separated from the backrest and the supports are connected by forming a single piece "Fig 6, Fig 7, Fig 8, Fig 9"; At the highest point of the supports, part of the hinge and the bolts for limiting the angle of rotation are attached "Fig 10 (1)". The other part of the hinge consists of "eyelets" "Fig 11 (1)", which allows the seat and the backrest to rotate until a bed is formed "Fig 12". This rotation can be regulated in stages with a rotary handle "Fig 11 (2)" which actuates a gearwheel within a toothed "eyelet" Fig 11 (3) "and, on the opposite side, with a bolt" Fig 11 (4) " and the associated other parts "Fig 11 (5)" for the determination of the different degrees of rotation.
