- the spring system 34 also includes a stop mechanism 38. At an end of the stand 24 facing away from the seat and support body 14, an end portion 40 of the stop mechanism 38 is arranged, which in Fig. 1 is shown in a retracted state, so that there is no contact with a flat surface and the seat and support furniture 10 can be moved by the movable roller system 36.
- Fig. 2 shows the seat and support body 24 in its second end position 12b, so that a user can use the support surface 20 for standing still.
- the support surface 20 is now substantially parallel to a horizontal plane of the seat 16 from Fig. 1 arranged, wherein the seat surface 16 in Fig. 2 substantially parallel to a vertical plane of the support surface 20 Fig. 1 is arranged. It follows that the seat and support body 14 has substantially bypassed a pivot angle of 90 degrees.
- the first hinge axis 32a of the spring 28 is arranged in a base plane, which is less far from the roller system 36 spaced apart from the horizontal axis 26. Both in Fig.

- Fig. 2 is the height-adjustable spring system 34 in an extended state, in this case the Eingelenk 32 is further spaced from the roller system 36 than in Fig. 1 ,
- the end portion 40 of the stop mechanism 38 is in an extended condition such that the end portion 40 of the stop mechanism 38 is spaced at least as far from the horizontal plane by the horizontal axis 26 as a side of the roller system 36 remote from the horizontal plane the end portion 40 of the stop mechanism 38 is in contact with a floor, thereby preventing movement of the roller system 36, so that the seat and backrest stand firmly when a user leans against the support surface 20 to sit still.
- the end portion 40 of the stop mechanism 38 is preferably made of a material such as hard rubber, plastic or a similar brakeable material.
- Fig. 3 shows the seat and support furniture 10 in a front view in the first end position 12a.
- this first end position 12a of the end portion 40 of the stop mechanism 38 is retracted so that the seat and support furniture 10 can be moved by the roller system 36.
- Fig. 4 shows the seat and support furniture 10 in a front view in the second end position 12b, wherein the stand 24 has the same height as in Fig. 3 and has not yet been moved by the spring system 34 in a lowered blocking position.
- the seat and backrest furniture 10 is not yet fully suitable for standing still, since the support surface 20 is too low for a normal sized adult.
- the seat and support furniture 10 can still be moved by means of the roller system 36 to the preferred position along a floor, in which the seat and support furniture 10 is to be used for standing still. So shows Fig. 4 that at not yet schreibnverêtm stand 24 of the end portion 40 of the stop mechanism 38 is retracted further.
- Fig. 5 shows the seat and backrest 10 again in a front view in the second end position 12b, in contrast to Fig. 4 the stand 24 has now been adjusted in height by means of the spring system 34, so that a greater distance between the roller system 36 and the support surface 20 has been achieved.
- the seat and backrest furniture 10 is at a height that the support surface 20 can be used by the user for standing still.
- the end area 40 of the stop mechanism 38 is extended so that a braking action which blocks the movable roller system is initiated by the contact of the end area 40 of the stop mechanism 38 with a base or floor.
- Fig. 1 shows that the seat and support body 14 includes a cover 42 which is disposed on a side facing away from the backrest 18 of the seat and support body 14. In this case, a surface of the cover part 42 forms the support surface 20. In Fig. 1 the cover 42 is shown in its retracted position, so that an upper end of the cover 42 does not protrude beyond the rest of the seat and support body 14.
- Fig. 5 shows the cover 42 in a partially extended position and Fig. 6 shows the cover 42 in its fully extended position.
- the fully extended cover part 42 an elongated backrest 19 is formed, which is formed in sections from the seat and support body 14 and from the cover 42.
- the cover part 42 is optionally connected to the seat and support body 14 via a sliding guide or linkage kinematics, the slide guide or linkage kinematics being coupled to the pivotal movement of the seat and support body 14 such that the cover part 32 is extended depending on the end position or retracted.

- the spring 28 supports the pivoting movement in the second end position 12b or can perform the pivoting about the horizontal axis 26 independently at a correspondingly high selected spring force.
- the spring system 34 has the properties that it triggers the stop mechanism 38 only at a predefined height by a vertical pressure force.
- the seat and backrest furniture 10 is not yet in an elevated height-adjusted position in the end position 12b, so that a vertical force exerted on the support surface 20 would not yet lead to an extension of the end area of the stop mechanism 40 , as well as it in Fig. 4 is shown.
- the spring system 34 adjusts the stand 24 a desired height, which, for example, the height in Fig. 5 equivalent. This height now exceeds the predefined height, from which the spring system 34 can extend the stop mechanism 38.
- the end portion 40 of the stop mechanism 38 moves as in Fig. 5 shown and thus blocks the movable roller system, whereby the seat and support furniture 10 now provides a secure fit for standing still.
- the spring system 24, both the Height adjustment ready as well as the property extend the end portion 40 of the stop mechanism 38 from a certain height adjustment.
- the user can now lock the seat and support furniture 10 in the second end position 12b. By loosening this lock, the seat and support furniture 10 can pivot from the second end position 12b back into the first end position 12a. At this time, the spring 28 damps the pivotal movement, i. the spring 28 is tensioned by manual pivoting. In a next step, the user releases the stop mechanism 38, so that the seat and backrest furniture 10 can be moved again by means of the roller system 36 and adjusts the stand 24 to a desired seat height.

Description
Die Erfindung betrifft Sitz- und Stützmöbel mit oder ohne Armlehne mit einem Sitz- und Stützkorpus, der eine Sitzfläche und eine Stützfläche aufweist, die durch Verschwenken des Sitz- und Stützkorpus einem Benutzer bereitgestellt werden.The invention relates to seat and support furniture with or without armrest with a seat and support body having a seat and a support surface, which are provided by pivoting the seat and support carcass to a user.
Es ist die Aufgabe der Erfindung, ein Sitz- und Stützmöbel mit oder ohne Armlehne mit einer Sitzfläche und einer Stützfläche anzugeben, das eine zuverlässige und benutzerfreundliche Bedienung ermöglicht.It is the object of the invention to provide a seat and support furniture with or without armrest with a seat and a support surface, which allows a reliable and user-friendly operation.
Diese Aufgabe wird erfindungsgemäß durch ein Sitz- und Stützmöbel mit oder ohne Armlehne mit den Merkmalen des unabhängigen Anspruchs 1 gelöst.This object is achieved by a seat and support furniture with or without armrest with the features of the independent claim 1.
Gemäß einem Aspekt der Erfindung ist ein Sitz- und Stützmöbel mit oder ohne Armlehne geschaffen, welches einen Ständer und einen Sitz- und Stützkorpus aufweist, wobei der Sitz- und Stützkorpus auf dem Ständer um zumindest eine horizontale Achse schwenkbar angeordnet ist. Dabei ist ein verfahrbares Rollensystem an den Ständer angeschlossen, weiches vorteilhaft gewährleistet, dass das Sitz- und Stützmöbel beispielsweise in einem Büro nicht getragen werden muss, sondern leicht verfahren werden kann. Hierbei weist der Ständer einen ausfahrbaren Stoppmechanismus auf, wobei der ausfahrbare Stoppmechanismus ab einer vordefinierten Höhe aktivierbar ist. Dabei ist der Stoppmechanismus durch eine vertikale Kraft auf den Sitz- und Stützkorpus auslösbar und blockiert dadurch ein an den Ständer angeschlossenes verfahrbares Rollensystem. Diese vertikale Kraft kann beispielsweise durch das Stehsitzen erzeugt werden. Die vertikale Kraft, die dazu nötig ist, um den Stoppmechanismus auszulösen, ist zweckmäßig allerdings deutlich kleiner gewählt als die Gewichtskraft eines typischen Benutzers, sodass beispielsweise auch ein Kind den Stoppmechanismus leicht auslösen kann. Insbesondere ist die aufzuwendende vertikale Kraft so klein, dass der Stoppmechanismus durch einen moderaten Druck der Hände auslösbar ist und das verfahrbare Rollensystem blockiert. Hierbei weist der Sitz- und Stützkorpus eine Sitzfläche auf, die in einer ersten Endposition einer Verschwenkung um die horizontale Achse im Wesentlichen in einer horizontalen Ebene angeordnet ist, wobei die Sitzfläche in einer zweiten Endposition der Verschwenkung quer zu der horizontalen Ebene angeordnet ist. Hierbei weist der Sitz- und Stützkorpus eine Stützfläche auf, die an einer von der Sitzfläche beabstandeten Seite des Sitz-und Stützkorpus angeordnet ist. An den Ständer ist ein erstes Ende einer Feder angeschlossen, wobei an dem Sitz- und Stützkorpus ein zweites Ende der Feder angeschlossen ist, und wobei die Feder eine Verschwenkung des Sitz-und Stützkorpus um die horizontale Achse unterstützt.According to one aspect of the invention, a seat and support furniture is provided with or without armrest, which has a stand and a seat and support body, wherein the seat and support body is pivotally mounted on the stand about at least one horizontal axis. In this case, a movable roller system is connected to the stand, soft advantageous ensures that the seat and support furniture, for example, in an office need not be worn, but can be easily moved. In this case, the stand on an extendable stop mechanism, wherein the extendable stop mechanism is activated from a predefined height. In this case, the stop mechanism is triggered by a vertical force on the seat and support body and thereby blocks a connected to the stand movable roller system. This vertical force can be generated, for example, by standing still. However, the vertical force needed to trigger the stop mechanism is desirably much smaller than the weight of a typical user so that, for example, a child can easily deploy the stop mechanism. In particular, the vertical force to be applied is so small that the stop mechanism by a moderate pressure of the hands is triggered and blocks the movable roller system. In this case, the seat and support body on a seat surface, which is arranged in a first end position of a pivoting about the horizontal axis substantially in a horizontal plane, wherein the seat is arranged in a second end position of the pivoting transversely to the horizontal plane. Here, the seat and support body on a support surface which is arranged on a side of the seat and support body spaced from the seat surface. A first end of a spring is connected to the stator, a second end of the spring being connected to the seat and support body, and the spring assisting pivoting of the seat and support body about the horizontal axis.
Indem die Sitzfläche in einer ersten Endposition der Verschwenkung um die horizontale Achse im Wesentlichen in einer horizontalen Ebene angeordnet ist, kann ein Benutzer diese Sitzfläche in der Art und Weise eines herkömmlichen Bürostuhls nutzen. Vorteilhaft ist nach der Verschwenkung des Sitz- und Stützkorpus die Stützfläche in einer derartigen Position angeordnet, dass die Stützfläche, alternativ zu der Sitzfläche, durch den Benutzer zum Zwecke des Stehsitzens verwendet werden kann. Vorteilhaft wird dadurch erreicht, dass ein einziges Sitz- und Stützmöbel zumindest zwei verschiedene Nutzpositionen für den Benutzer bereitstellt. Dadurch, dass die Sitzfläche in der zweiten Endposition quer, vorzugsweise in etwa senkrecht zu der horizontalen Ebene angeordnet ist, ist die Sitzfläche im Wesentlichen parallel zu dem Ständer in Richtung eines Bodens angeordnet und behindert dadurch den Benutzer nicht, wenn sich dieser an der Stützfläche zum Stehsitzen auflehnt. Dadurch, dass das erste Ende der Feder an dem Ständer und das zweite Ende der Feder an dem Sitz- und Stützkorpus angeordnet ist, wird die Schwenkbewegung vorteilhaft unterstützt, sodass ein Benutzer eine geringe Kraft zum Verschwenken aufwenden muss, wobei andererseits vorteilhaft auch die Verschwenkung zurück in die erste Endposition gedämpft wird, sodass Bauteile des Sitz- und Stützmöbels nicht unnötig belastet werden und zugleich akustische Geräusche gedämpft werden.By arranging the seat surface in a first end position of pivot about the horizontal axis substantially in a horizontal plane, a user can utilize this seat in the manner of a conventional office chair. Advantageously, after the pivoting of the seat and support body, the support surface is arranged in such a position that the support surface, alternatively to the seat surface, can be used by the user for the purpose of standing still. Advantageously, it is achieved that a single seat and support furniture provides at least two different use positions for the user. Characterized in that the seat surface in the second end position is arranged transversely, preferably approximately perpendicular to the horizontal plane, the seat surface is arranged substantially parallel to the stand in the direction of a floor and thus does not hinder the user when it is on the support surface for Standing sitting revolted. Characterized in that the first end of the spring on the stand and the second end of the spring is arranged on the seat and support body, the pivoting movement is advantageously supported, so that a user a small force to On the other hand, it is advantageous to also apply the pivoting back to the first end position, so that components of the seat and support furniture are not unnecessarily loaded and at the same time acoustic noise is damped.
Bevorzugt spannt die Feder den Sitz- und Stützkorpus in Richtung auf die zweite Endposition der Verschwenkung vor. Ein Schwerpunkt des Sitz- und Stützkorpus ist dahingehend ausgestaltet, dass die Feder, indem sie in Richtung auf die zweite Endposition der Verschwenkung vorgespannt ist, den Öffnungsvorgang vorteilhaft unterstützt, sodass ein Benutzer weniger Kraft für die Verschwenkung aufwenden muss. Zugleich wird ein unkontrolliertes Verschwenken des Sitz- und Stützkorpus von seiner ersten Endposition in seine zweite Endposition gedämpft.Preferably, the spring biases the seat and support body in the direction of the second end position of the pivoting. A center of gravity of the seat and support body is designed such that the spring, by being biased towards the second end position of the pivot, advantageously supports the opening operation, so that a user must expend less force for the pivoting. At the same time an uncontrolled pivoting of the seat and support body is attenuated from its first end position to its second end position.
Zweckmäßigerweise ist das erste Ende der Feder verschwenkbar an dem Ständer angeschlossen, sodass die Feder vorteilhaft mitschwenkbar angeschlossen ist. Durch das verschwenkbare Anschließen der Feder an den Ständer wird das erste Ende der Feder vorteilhaft an dem stabilen Ständer gelagert, sodass Druckkräfte, welche bei einer Verschwenkung des Sitz- und Stützkorpus entstehen, keine instabilen Bauteile beschädigen, sondern von dem robusten Ständer aufgenommen werden. Das verschwenkbare Anschließen des ersten Lenkers an den Ständer ermöglicht, dass die Feder die Schwenkbewegung des Sitz- und Stützkorpus unterstützen bzw. abfedern kann. Um ein Drehmoment auf den Sitz- und Stützkorpus auszuüben, ist zumindest ein Ende der Feder gegen ein außerhalb des Sitz- und Stützkorpus angeordnetes Teil abgestützt.Conveniently, the first end of the spring is pivotally connected to the stand, so that the spring is advantageously pivotally connected. By the pivotable connection of the spring to the stator, the first end of the spring is advantageously mounted on the stable stand, so that compressive forces, which arise during pivoting of the seat and support body, damage any unstable components, but are absorbed by the robust stand. The pivotable connection of the first link to the stand allows the spring to assist or cushion the pivotal movement of the seat and support body. In order to exert a torque on the seat and support body, at least one end of the spring is supported against a part arranged outside the seat and support body.
Bevorzugt ist das zweite Ende der Feder verschwenkbar an dem Sitz- und Stützkorpus angeschlossen. Vorteilhaft wird dadurch ermöglicht, dass die Feder mitschwenkbar angeordnet ist und die unterstützende Kraftwirkung der Feder bei der Verschwenkung direkt auf den Sitz- und Stützkorpus übertragen wird, ohne dass zusätzliche Bauteile verwendet werden müssen.Preferably, the second end of the spring is pivotally connected to the seat and support body. Advantageously, it is made possible that the spring is pivotally mounted and the supporting force of the spring is transmitted during the pivoting directly to the seat and support carcass without additional components must be used.
Bevorzugt verläuft zumindest eine Gelenkachse der Feder parallel zu der horizontalen Achse. Vorteilhaft wird dadurch erreicht, dass das durch die Feder erzeugte Drehmoment optimal genutzt werden kann, um die Verschwenkung des Sitz- und Stützkorpus um die horizontale Achse zu unterstützen.At least one hinge axis of the spring preferably runs parallel to the horizontal axis. Advantageously, it is achieved that the torque generated by the spring can be optimally used to assist the pivoting of the seat and support body about the horizontal axis.
Gemäß einer bevorzugten Ausgestaltung sind die Stützfläche und die Sitzfläche in einem feststehenden Einschlusswinkel zueinander an dem Sitz-und Stützkorpus angeordnet. Vorteilhaft ergibt sich daraus, dass der Sitz- und Stützkorpus einstückig ausgebildet sein kann und dadurch eine hohe Stabilität aufweist. Diese hohe Stabilität ist deswegen vorteilhaft, da nicht nur die Sitzfläche, sondern auch die Stützfläche beim Stehsitzen das Gewicht eines Benutzers trägt. Alternativ ist es möglich, den Stütz- und Sitzkorpus zweistückig auszubilden. Dies würde allerding ein zusätzliches Bauteil erforderlich machen, welches die Sitzfläche und die Stützfläche stabil und sicher verbindet.According to a preferred embodiment, the support surface and the seat surface are arranged at a fixed inclusion angle to each other on the seat and support body. Advantageous results from the fact that the seat and support body can be integrally formed and thereby has a high stability. This high stability is advantageous because not only the seat, but also the support surface carries the weight of a user standing still. Alternatively, it is possible to form the support and seat body in two pieces. This would make it all an additional component required, which connects the seat and the support surface stable and secure.
Vorteilhaft begrenzen die erste und die zweite Endposition einen Schwenkbereich, der dem Einschlusswinkel zwischen der Stützfläche und der Sitzfläche entspricht. Im Allgemeinen ist der Einschlusswinkel zwischen der Sitzfläche und einer Rückenlehne bei einem Sitz- und Stützmöbel in etwa 90 Grad. Vorliegend befindet sich die Rückenlehne auf der entgegensetzten Seite der Stützfläche, sodass die Sitzfläche auch mit der Stützfläche einen Einschlusswinkel von in etwa 90 Grad ausbildet. Dadurch, dass der Schwenkbereich diesem Einschlusswinkel entspricht, wird vorteilhaft gewährleistet, dass die Sitzfläche in der zweiten Endposition parallel zur Erstreckung des Ständers angeordnet ist und den Benutzer nicht in seinem Bewegungsspielraum behindert, wenn er sich zum Stehsitzen auf der Stützfläche anlehnen will. Zudem wird dadurch gewährleistet, dass die Sitz- und Stützfläche nach der Schwenkbewegung im Wesentlichen in der gleichen horizontalen Ebene wie die Sitzfläche vor der Verschwenkung angeordnet ist, so dass die Last des Benutzers mit wenig Momenten in den Ständer eingeleitet wird.Advantageously, the first and second end positions define a pivoting range which corresponds to the angle of confinement between the support surface and the seat surface. In general, the inclusion angle between the seat and a backrest in a seating and support furniture is about 90 degrees. In the present case, the backrest is located on the opposite side of the support surface, so that the seat also forms an inclusion angle of about 90 degrees with the support surface. Characterized in that the pivoting area corresponds to this inclusion angle, it is advantageously ensured that the seat surface is arranged in the second end position parallel to the extension of the stand and does not hinder the user in his range of motion, if he wants to lean on the support surface for standing still. In addition, this ensures that the seat and support surface is arranged after the pivoting movement substantially in the same horizontal plane as the seat before pivoting, so that the load of the user is introduced with little moment in the stand.
Bevorzugt ist die horizontale Achse in einem Kugelgelenk verwirklicht, wobei das Kugelgelenk eine dreidimensionale Bewegung des Sitz- und Stützkorpus ermöglicht. Eine dreidimensionale Bewegung des Sitz- und Stützkorpus aktiviert vorteilhaft die untere Rücken- und Gesäßmuskulatur des Benutzers, wodurch diese gestärkt werden und möglichen Rückenbeschwerden vorbeugt.Preferably, the horizontal axis is realized in a ball joint, wherein the ball joint allows a three-dimensional movement of the seat and support body. A three-dimensional movement of the seat and support body advantageously activates the user's lower back and buttock muscles, strengthening them and preventing possible back problems.
Alternativ ist die horizontale Achse in einem Eingelenk aufgenommen, wobei das Eingelenk die Verschwenkung um die horizontale Achse ermöglicht. Vorteilhaft gewährleistet das Eingelenk eine sehr stabile Art der Verschwenkung um die horizontale Achse, die Robustheit und Langlebigkeit des Verschwenkungsmechanismus garantiert. Eine weitere alternative gelenkige Verbindung kann z. B. durch ein Viergelenk bereitgestellt werden.Alternatively, the horizontal axis is received in a pivot, wherein the pivot allows the pivoting about the horizontal axis. Advantageously, the Eingelenk ensures a very stable type of pivoting about the horizontal axis, the robustness and longevity of Verschwenkungsmechanismus guaranteed. Another alternative articulated connection may, for. B. be provided by a four-bar linkage.
Gemäß einer bevorzugten Ausgestaltung des Sitz- und Stützmöbels ist das erste Ende der Feder nahe der horizontalen Achse angeschlossen. Hierdurch wird erreicht, dass schon eine kleine Auslenkung der Feder ausreicht, um einen großen Verschwenkungswinkel zu ermöglichen.According to a preferred embodiment of the seat and support furniture, the first end of the spring is connected near the horizontal axis. This ensures that even a small deflection of the spring is sufficient to allow a large Verschwenkungswinkel.
Zweckmäßigerweise ist das erste Ende der Feder außerhalb einer in der Regel vertikalen Achse des Ständers angeordnet. Hierdurch wird vorteilhaft erreicht, dass das erste Ende der Feder außerhalb des Ständers an den Ständer angeschlossen werden kann und nicht in den Ständer eingebaut werden muss, sodass die Feder bei einer eventuellen Fehlfunktion leichter austauschbar ist.Conveniently, the first end of the spring is disposed outside of a generally vertical axis of the stator. This advantageously ensures that the first end of the spring outside the stand can be connected to the stand and does not need to be installed in the stand, so that the spring is easily replaceable in case of malfunction.
Bevorzugt ist das erste Ende der Feder außerhalb der horizontalen Achse angeordnet. Hierdurch wird vorteilhaft erreicht, dass ein Drehmoment, welches durch die Feder erzeugt wird, bezüglich der horizontalen Achse, einen Hebelarm mit einer Länge ungleich Null zugeordnet bekommt, sodass die Federkraft die Verschwenkung um die horizontale Achse unterstützen kann.Preferably, the first end of the spring is arranged outside the horizontal axis. In this way, it is advantageously achieved that a torque, which is generated by the spring, with respect to the horizontal axis, a lever arm assigned to a length not equal to zero, so that the spring force can support the pivoting about the horizontal axis.
Bevorzugt ist das erste Ende der Feder in einer Basisebene unterhalb der horizontalen Achse angeschlossen. Hierdurch wird vorteilhaft gewährleistet, dass ein Drehmoment an den Sitz- und Stützkorpus bzgl. der horizontalen Achse wirkbar angreifen kann.Preferably, the first end of the spring is connected in a base plane below the horizontal axis. This advantageously ensures that a torque with respect to the seat and support body with respect to the horizontal axis can attack effectively.
In einer weiteren Ausgestaltung der Erfindung ist das zweite Ende der Feder nahe der Stützfläche angeordnet.In a further embodiment of the invention, the second end of the spring is arranged near the support surface.
Vorzugsweise ist das zweite Ende der Feder in einer Wanderebene oberhalb der horizontalen Achse und vorzugsweise parallel zu der Basisebene angeordnet. Indem das erste Ende der Feder unterhalb der horizontalen Achse in der Basisebene angeordnet ist und das zweite Ende der Feder überhalb der horizontalen Achse in einer Wanderebene angeordnet ist, wird ermöglicht, dass die Feder die Schwenkbewegung von der ersten Endposition in die zweite Endposition durch den Benutzer unterstützt und zugleich die Verschwenkung von der zweiten Endposition in die erste Endposition vorteilhaft dämpft, da die Feder ein wirksames Drehmoment bzgl. der horizontalen Achse ausübt. Hierbei erfolgt die Schwenkbewegung in eine Schwenkrichtung, welche durch die Federkraft vorgegeben ist.Preferably, the second end of the spring is arranged in a traveling plane above the horizontal axis and preferably parallel to the base plane. By placing the first end of the spring below the horizontal axis in the base plane and the second end of the spring above the horizontal axis in a traveling plane, the spring is allowed to pivot by the user from the first end position to the second end position supports and at the same time advantageously damps the pivoting from the second end position to the first end position, since the spring exerts an effective torque with respect to the horizontal axis. Here, the pivoting movement takes place in a pivoting direction, which is predetermined by the spring force.
Zweckmäßigerweise bildet eine der Stützfläche gegenüberliegende Seite des Sitz- und Stützkorpus eine Rückenlehne aus. Vorteilhaft wird dadurch erreicht, dass sich der Benutzer auch in der ersten Endposition in einer gemütlichen Position auf dem Sitz- und Stützmöbel zurücklehnen kann.Conveniently, one of the support surface opposite side of the seat and support body forms a backrest. Advantageously, it is achieved that the user can also lean back in the first end position in a comfortable position on the seating and support furniture.
Zweckmäßigerweise weist die Rückenlehne eine konkave Form auf, sodass sie sich der Struktur des Rückens eines Benutzers auf angenehme Weise anschmiegen kann.Conveniently, the backrest has a concave shape, so that it can conform to the structure of the back of a user in a pleasant way.
Bevorzugt sind die Stützfläche und die Rückenlehne mit unterschiedlichem Material umkleidet. Vorteilhaft kann dadurch erreicht werden, dass die Stützfläche, welche zum Stehsitzen verwendet wird und die Rückenlehne, welche zum Anlehnen verwendet wird, zwei unterschiedliche Materialien aufweisen, die speziell an die Bedürfnisse von Unterbekleidung wie etwa Hosen und die Rückenlehne an Oberbekleidung wie etwa Hemden oder Pullover angepasst ist. Zudem ist die Möglichkeit gegeben, dass die Rückenlehne beispielsweise mit einer Massagefunktion ausgebildet sein kann.Preferably, the support surface and the backrest are covered with different material. Advantageously, it can be achieved that the support surface used for standing and the backrest used for leaning have two different materials, especially to the needs of undergarments such as pants and the back of outerwear such as shirts or sweaters is adjusted. In addition, there is the possibility that the backrest may be formed, for example, with a massage function.
Alternativ sind die Stützfläche und die Rückenlehne mit identischem Material umkleidet.Alternatively, the support surface and the backrest are covered with identical material.
Zweckmäßigerweise sind die Sitzfläche und die Stützfläche mit unterschiedlichem Material ausgekleidet. Vorteilhaft kann dadurch erreicht werden, dass die Sitzfläche beispielsweise mit einem Material umkleidet ist, welches bevorzugt in kälteren Wintermonaten verwendet wird, wobei die Stützfläche mit einem Material umkleidet ist, welches besonders feuchtigkeitsdurchlässig ist, sodass beispielsweise in warmen Sommermonaten Schweiß zügig von dem Benutzer abtransportiert wird. Alternativ sind die Stützfläche und die Sitzfläche mit identischem Material umkleidet.Conveniently, the seat and the support surface are lined with different material. Advantageously, it can be achieved that the seat is, for example, covered with a material, which is preferably used in colder winter months, wherein the support surface is covered with a material which is particularly moisture permeable, so that, for example, in warm summer months sweat is transported away quickly by the user , Alternatively, the support surface and the seat are covered with identical material.
Gemäß einer bevorzugten Ausgestaltung umfasst der Sitz- und Stützkorpus eine formsteife Tragstruktur, wobei die Tragstruktur die Sitzfläche und die Stützfläche verstärkt und aussteift. Vorteilhaft gewährleistet die formsteife Tragstruktur einen stabilen Sitz- und Stützkorpus. Bei herkömmlichen Stühlen wird die Hauptlast von der Sitzfläche getragen, wohingegen die Rückenlehne bzw. die Stützfläche nur einen Bruchteil der Gewichtskraft des Benutzers aufzunehmen haben und deshalb weniger formsteif und verstärkt ausgebildet sein müssen. Vorteilhaft gewährleistet die formsteife Tragstruktur sowohl eine Verstärkung der Sitzfläche als auch eine Verstärkung der Rückenlehne bzw. der Stützfläche, da es vorgesehen ist, dass der Benutzer wahlweise sein Gewicht auf der Sitzfläche bzw. auf der Stützfläche ablegt. Zu diesem Zweck ist sowohl die Sitzfläche als auch die Stützfläche in der Lage, die volle Gewichtskraft des Benutzers zu tragen.According to a preferred embodiment, the seat and support body comprises a dimensionally stable support structure, wherein the support structure reinforces and stiffen the seat surface and the support surface. Advantageously, the dimensionally stable support structure ensures a stable seat and support carcass. In conventional chairs, the main load is carried by the seat, whereas the backrest or the support surface have to absorb only a fraction of the weight of the user and therefore must be less dimensionally rigid and reinforced. Advantageously, the dimensionally stable support structure ensures both a reinforcement of the seat surface and a reinforcement of the backrest or the support surface, since it is provided that the user optionally deposits his weight on the seat surface or on the support surface. For this purpose, both the seat surface and the support surface are able to support the full weight of the user.
Bevorzugt umfasst die Tragstruktur winkelförmige Streben. Die winkelförmigen Streben sind insbesondere deshalb vorteilhaft, da eine natürlich Sitzposition eines Benutzers im Wesentlichen einen winkelförmigen Verlauf aufweist, sodass die winkelförmigen Streben die Körperstruktur gut wiedergeben und abstützen können.Preferably, the support structure comprises angular struts. The angle-shaped struts are particularly advantageous because a natural sitting position of a user has substantially an angular course, so that the angle-shaped struts can reproduce and support the body structure well.
Zweckmäßigerweise ist die Tragstruktur einstückig ausgebildet. Vorteilhaft wird dadurch gewährleistet, dass die Tragstruktur zeit- und kostengünstig herstellbar ist, da zusätzliche Montagearbeiten entfallen. Alternativ kann die Tragstruktur jedoch auch zweistückig oder mehrstückig ausgebildet sein.Conveniently, the support structure is integrally formed. Becomes advantageous thereby ensuring that the support structure can be produced time and cost, since additional installation work accounts. Alternatively, however, the support structure may also be formed in two pieces or in several pieces.
Bevorzugt rotieren die Sitzfläche und die Stützfläche synchron um den gleichen Winkel. Alternativ rotiert die Sitzfläche um einen kleineren Winkel als die Stützfläche, wodurch vorteilhaft eine Kollision mit dem Ständer verhindert werden kann.Preferably, the seat and the support surface rotate synchronously by the same angle. Alternatively, the seat surface rotates by a smaller angle than the support surface, whereby advantageously a collision with the stand can be prevented.
Gemäß einer bevorzugten Ausgestaltung sind Anschlaggeräusche, welche bei der Verschwenkung zwischen der ersten und der zweiten Endposition entstehen, durch einen Puffer, der zwischen beweglichen Bauteilen angeordnet ist, akustisch dämpfbar. Hieraus folgt, dass sowohl Bauteile des Sitz- und Stützmöbels geschont werden, da durch die Dämpfung eine Materialschonung ermöglicht wird und dass der Stuhl einen hochwertigeren Eindruck macht, indem die Verschwenkung möglichst leise vonstattengeht und dadurch auch beispielsweise in einem Büro andere Mitarbeiter nicht gestört werden, wenn der Benutzer das Sitz- und Stützmöbel von der ersten Endposition in die zweite Endposition und zurück verschwenkt.According to a preferred embodiment, stop noises, which arise during the pivoting between the first and the second end position, are acoustically attenuatable by a buffer which is arranged between movable components. It follows that both components of the seat and support furniture are spared because the cushioning a material protection is made possible and that the chair makes a higher quality impression by the pivoting as quiet as possible vonstattengeht and thus other employees are not disturbed, for example, in an office, when the user pivots the seat and backrest furniture from the first end position to the second end position and back.
Zweckmäßigerweise ist das Verschwenken durch einen Mechanismus triggerbar, der eine Verriegelung löst. Bei diesem Mechanismus kann es sich wahlweise um einen Knopf, einen Hebel oder auch eine elektronische Vorrichtung handeln, die die Verriegelung erst freigibt, nachdem der Benutzer, ein Sensor oder ein anderes wohldefiniertes Auslösesignal den Mechanismus triggert. Hierdurch wird vorgebeugt, dass sich das Sitz- und Stützmöbel unbeabsichtigt von der einen Endposition in die zweite Endposition verschwenkt. Zugleich wird aber auch die Möglichkeit bereitgestellt, dass der Sitz- und Stützkorpus zu einem wohldefinierten Zeitpunkt automatisch verschwenken kann. Alternativ kann der Mechanismus auch solange manuell betätigt werden, bis eine gewünschte Position erreicht ist. Wahlweise kann es sich hierbei um eine der Endpositionen oder um eine Zwischenposition handeln.Conveniently, the pivoting is triggered by a mechanism that releases a lock. Optionally, this mechanism may be a knob, lever, or electronic device that releases the latch only after the user, sensor, or other well-defined trigger signal triggers the mechanism. This prevents that the seat and support furniture unintentionally pivoted from one end position to the second end position. At the same time, however, the possibility is provided that the seat and support body can automatically pivot at a well-defined time. Alternatively, the mechanism can be operated manually until a desired position is reached. Optionally, this may be one of the end positions or an intermediate position.
Vorzugsweise ist die Stützfläche in einer zweiten Endposition in einer horizontalen Ebene angeordnet. Dies ermöglicht, dass die Stützfläche durch einen Benutzer bequem zum Stehsitzen geeignet ist.Preferably, the support surface is arranged in a second end position in a horizontal plane. This allows the support surface to be comfortably seated by a user.
Gemäß einer bevorzugten Ausgestaltung weist die Stützfläche eine leicht konvexe Form auf. Durch diese leicht konvexe Form wird ermöglicht, dass in der zweiten Endposition die Stützfläche zum Stehsitzen geeignet ist, und sich die Stützfläche der Körperstruktur eines Benutzers im Gesäßbereich anpasst. Alternativ kann die Stützfläche auch eine im Wesentlichen flache Ebene ausbilden.According to a preferred embodiment, the support surface has a slightly convex shape. By this slightly convex shape is made possible that in the second end position, the support surface is suitable for standing still, and adapts the support surface of the body structure of a user in the buttocks area. Alternatively, the support surface can also form a substantially flat plane.
Bevorzugt ist die Feder durch ein Verriegelungsmittel verriegelbar. Die Feder unterstützt die Schwenkbewegung von der ersten Endposition in die zweite Endposition und dämpft die Schwenkbewegung von der zweiten Endposition zurück in die erste Endposition. Durch ein Verriegelungsmittel, welches die Feder verriegelt, wird vorteilhaft gewährleistet, dass die Unterstützung bzw. die Dämpfung nur nach Wunsch eines Benutzers und nicht unbeabsichtigt eintritt. Sowohl in der ersten Endposition als auch in der zweiten Endposition kann damit eine Verriegelung und Feststellung der jeweiligen Position gewährleistet werden. Alternativ ist die Feder in einer beliebigen Zwischenposition verriegelbar.Preferably, the spring can be locked by a locking means. The spring supports pivotal movement from the first end position to the second end position and dampens the pivotal movement from the second end position back to the first end position. By a locking means which locks the spring, it is advantageously ensured that the support or the damping occurs only at the request of a user and not unintentionally. Both in the first end position and in the second end position so that a lock and determination of the respective position can be ensured. Alternatively, the spring can be locked in any intermediate position.
Zweckmäßigerweise ist das Verriegelungsmittel durch einen Betätigungsknopf freigebbar. Dieser Betätigungsknopf ist vorzugsweise so angeordnet, dass dieser einerseits nicht zufällig durch den Benutzer ausgelöst wird, aber andererseits auch gut erreichbar ist, falls der Benutzer das Sitz- und Stützmöbel verschwenken möchte. Hierzu kann beispielsweise eine der Sitzfläche abgekehrte Seite des Sitz- und Stützkorpus zur Aufnahme des Betätigungsknopfs vorgesehen sein.Conveniently, the locking means can be released by an actuating button. This actuator button is preferably arranged so that this one hand, not accidentally triggered by the user, but on the other hand is also easily accessible, if the user would like to pivot the seat and support furniture. For this purpose, for example, a seat facing away from the side of the seat and support body may be provided for receiving the actuating knob.
Gemäß einer weiteren Ausgestaltung ist die Feder in den Sitz- und Stützkorpus aufgenommen. Dies hat den Vorteil, dass die Feder vor Beschädigungen von außerhalb durch den Sitz- und Stützkorpus geschützt ist und dass beispielsweise vermieden wird, dass die Finger eines Benutzers zwischen die beweglichen Teile der Gelenke, an welchen die Feder angelenkt ist, kommen und dadurch verletzt werden.According to a further embodiment, the spring is received in the seat and support body. This has the advantage that the spring is protected from damage is protected outside by the seat and support body and that, for example, it is avoided that the fingers of a user between the moving parts of the joints to which the spring is hinged, come and thereby be injured.
Gemäß einer bevorzugten Ausgestaltung des Sitz- und Stützmöbels ist die Feder als Gasfeder ausgebildet. Vorteilhaft kann die Gasfeder die Verschwenkung durch einen kleinen Federweg bereitstellen, zudem weist die Gasfeder eine vom Federweg nahezu unabhängige Kraft auf. Alternativ kann die Feder auch als Schraubenfeder, Winkelfeder, Schenkelfeder oder anderer Federtyp ausgebildet sein.According to a preferred embodiment of the seat and support furniture, the spring is designed as a gas spring. Advantageously, the gas spring provide the pivoting by a small spring travel, also, the gas spring on a spring force almost independent of power. Alternatively, the spring may also be formed as a helical spring, angle spring, leg spring or other spring type.
Bevorzugt ist der Ständer durch ein von der vorgenannten Feder unabhängiges Federsystem höhenverstellbar. Hierbei ist das Federsystem in Richtung auf eine höhere Sitzflächenposition vorgespannt. Schon bei bekannten Bürostühlen ist die Höhenverstellbarkeit eine wichtige Eigenschaft, um das Sitz- und Stützmöbel auf die Bedürfnisse eines Benutzers anzupassen. Vorliegend kommt weiter hinzu, dass, selbst wenn die Sitzposition an einen Benutzer angepasst wäre, das Sitz- und Stützmöbel nach der Verschwenkung in die zweite Endposition neu in seiner Höhe verstellt werden kann, um dem Benutzer ein angenehmes Stehsitzen zu ermöglichen; dies wird vorteilhaft durch das höhenverstellbare Federsystem im Ständer ermöglicht.Preferably, the stand is height adjustable by a spring system independent of the aforementioned spring. Here, the spring system is biased towards a higher seating position. Already in known office chairs, the height adjustment is an important feature to adapt the seating and support furniture to the needs of a user. In the present case further adds that, even if the sitting position would be adapted to a user, the seat and support furniture after pivoting in the second end position can be adjusted in height again to allow the user a comfortable sitting; This is advantageously made possible by the height-adjustable spring system in the stand.
Zweckmäßigerweise ist das Federsystem in dem Ständer aufgenommen. Hierdurch wird kein unnötiger Raum durch das Federsystem beansprucht, wobei das Federsystem zugleich von dem Ständer umkleidet wird, sodass ein optisch ansprechenderes Erscheinungsbild resultiert. Des Weiteren verhindert die Umkleidung des Federsystems, dass beispielsweise Finger eines Benutzers zwischen die beweglichen Teile des Federsystems gelangen und dadurch verletzt werden können.Conveniently, the spring system is received in the stand. As a result, no unnecessary space is claimed by the spring system, wherein the spring system is also covered by the stand, so that a visually pleasing appearance results. Furthermore, the casing of the spring system prevents, for example, the fingers of a user get between the moving parts of the spring system and can be injured.
Gemäß einem Aspekt der Erfindung ist ein Sitz- und Stützmöbel mit oder ohne Armlehne geschaffen, welches einen Ständer und einen Sitz- und Stützkorpus aufweist, wobei der Sitz- und Stützkorpus auf dem Ständer um zumindest eine horizontale Achse schwenkbar angeordnet ist. Der Sitz- und Stützkorpus weist eine Sitzfläche auf, die in einer ersten Endposition in einer Verschwenkung um die horizontale Achse im Wesentlichen einer horizontalen Ebene angeordnet ist, wobei die Sitzfläche in einer zweiten Endposition der Verschwenkung quer zu der horizontalen Ebene angeordnet ist. Der Sitz- und Stützkorpus weist eine Stützfläche auf, die an einer von der Sitzfläche beabstandeten Seite des Sitz-und Stützkorpus angeordnet ist, wobei der Ständer einen ausfahrbaren Stoppmechanismus aufweist, und wobei der ausfahrbare Stoppmechanismus ab einer vordefinierten Höhe aktivierbar ist.According to one aspect of the invention, a seat and support furniture is provided with or without armrest, which has a stand and a seat and support body, wherein the seat and support body is pivotally mounted on the stand about at least one horizontal axis. The seat and support body has a seat surface which is disposed in a first end position in a pivot about the horizontal axis substantially a horizontal plane, wherein the seat surface is arranged in a second end position of the pivoting transverse to the horizontal plane. The seat and support body has a support surface disposed on a side of the seat and support body spaced from the seat surface, the stand having an extendible stop mechanism, and wherein the extendable stop mechanism is activatable from a predefined height.
Der ausfahrbare Stoppmechanismus ermöglicht vorteilhaft, dass das Sitz- und Stützmöbel, an welches z.B. ein verfahrbares Rollensystem angeschlossen ist, sicher an einem Boden festgestellt werden kann, sodass ein unabsichtliches Verfahren des Sitz- und Stützmöbels verhindert wird. Der ausfahrbare Stoppmechanismus ist vorteilhaft erst ab einer bestimmten Höhe aktivierbar, da bevorzugt der Stoppmechanismus nur in der zweiten Endposition beim Stehsitzen eingesetzt werden soll, welche höher ist als die erste Endposition, welche zum Sitzen verwendet wird. Ist der Sitz- und Stützkorpus des Sitz- und Stützmöbels in der ersten Endposition, sitzt der Benutzer auf der Sitzfläche, sodass das Verfahren des Sitz- und Stützmöbels durch das Rollensystem wie bei gängigen Bürostühlen sogar erwünscht ist. Beim Stehsitzen in der zweiten Endposition jedoch ist es wünschenswert, dass das verfahrbare Rollensystem blockiert wird. Dies wird durch den Stoppmechanismus realisiert.The extendable stop mechanism advantageously allows the seating and support furniture, to which e.g. a movable roller system is connected, can be safely detected on a floor, so that an unintentional procedure of the seat and support furniture is prevented. The extendable stop mechanism is advantageously activated only above a certain height, since preferably the stop mechanism is to be used only in the second end position when standing still, which is higher than the first end position, which is used for sitting. If the seat and support body of the seat and support furniture in the first end position, the user sits on the seat so that the procedure of the seat and support furniture through the roller system as in common office chairs is even desirable. When standing still in the second end position, however, it is desirable that the traveling roller system be blocked. This is realized by the stop mechanism.
Bevorzugt ist der Ständer durch ein Federsystem höhenverstellbar, dies gewährleistet, dass der Benutzer seine Wunschposition einstellen kann. Hierbei ist das Federsystem in Richtung auf eine höhere Sitzflächenposition vorgespannt, sodass die Gewichtskraft des Sitz- und Stützkorpus vorteilhaft gekontert wird.Preferably, the stand is height adjustable by a spring system, this ensures that the user can adjust his desired position. Here, the spring system is in the direction of a higher seat surface position biased, so that the weight of the seat and support body is advantageously countered.
In einer bevorzugten Weiterentwicklung weist das Federsystem den Stoppmechanismus auf, wobei der Stoppmechanismus durch das Federsystem steuerbar ist. Dies gewährleistet vorteilhaft, dass das höhenverstellbare Federsystem zugleich den Stoppmechanismus steuert, sodass keine zusätzliche Einrichtung für das Feststellen eines Rollensystems notwendig ist.In a preferred refinement, the spring system has the stop mechanism, wherein the stop mechanism can be controlled by the spring system. This advantageously ensures that the height-adjustable spring system at the same time controls the stop mechanism, so that no additional device for detecting a roller system is necessary.
Vorzugsweise ist der Stoppmechanismus des Federsystems verriegelbar und durch einen Mechanismus lösbar. Dies gewährt vorteilhaft, dass der Stoppmechanismus nicht unbeabsichtigt gelöst wird, sodass sich das Sitz- und Stützmöbel durch das Rollensystem verfahren lässt. Hierdurch wird verhindert, dass sich ein Benutzer beispielsweise an das Sitz- und Stützmöbel anlehnt, welches der Kraft nachgeben und wegfahren würde, sodass unter Umständen der Benutzer verletzt werden würde.Preferably, the stop mechanism of the spring system is lockable and releasable by a mechanism. This advantageously ensures that the stop mechanism is not unintentionally released, so that the seat and support furniture can be moved through the roller system. This prevents a user, for example, leaning against the seat and support furniture, which would yield to the force and drive away, so that in some circumstances the user would be injured.
Bevorzugt ist ein der Sitzfläche abgekehrter Endbereich des Stoppmechanismus mit einem bremsfähigen Material wie Hartgummi, Kautschuk, Plastik oder einem anderen bremsfähigen Material umkleidet.Preferably, a seat portion facing away from the end portion of the stop mechanism is covered with a brake material such as hard rubber, rubber, plastic or other brake-resistant material.
Gemäß einem Aspekt ist ein Sitz- und Stützmöbel mit oder ohne Armlehne geschaffen, welches einen Ständer und einen Sitz- und Stützkorpus aufweist, wobei der Sitz- und Stützkorpus auf dem Ständer um zumindest eine horizontale Achse schwenkbar angeordnet ist. Der Sitz- und Stützkorpus weist eine Sitzfläche auf, die in einer ersten Endposition in einer Verschwenkung um die horizontale Achse im Wesentlichen in einer horizontalen Ebene angeordnet ist, wobei die Sitzfläche in einer zweiten Endposition der Verschwenkung quer zu der horizontalen Ebene angeordnet ist. Der Sitz- und Stützkorpus weist eine Stützfläche auf, die an einer von der Sitzfläche beabstandeten Seite des Sitz-und Stützkorpus angeordnet ist, wobei an dem Sitz- und Stützkorpus ein Abdeckteil beweglich angeschlossen ist, und wobei das Abdeckteil gegenüber dem Sitz- und Stützkorpus verlagerbar ist, sodass auf einer der Stützfläche abgewandten Seite des Sitz- und Stützkorpus durch das ausgefahrene Abdeckteil eine verlängerte Rückenlehne ausgebildet ist, deren Oberfläche abschnittsweise aus dem Sitz- und Stützkorpus und aus dem Abdeckteil ausgebildet ist.In one aspect, there is provided a seat and backrest with or without an armrest having a stand and a seat and support body, the seat and support body being pivotally mounted on the stand about at least one horizontal axis. The seat and support body has a seat surface which is disposed in a first end position in a pivoting about the horizontal axis substantially in a horizontal plane, wherein the seat surface is arranged in a second end position of the pivoting transverse to the horizontal plane. The seat and support body has a support surface disposed on a side of the seat and support body spaced from the seat surface, a cover member being movably connected to the seat and support body, and the cover member being displaceable relative to the seat and support body is, so that on a side facing away from the support surface of the seat and support body by the extended cover an elongated backrest is formed, whose surface is formed in sections from the seat and support body and from the cover.
Dies ermöglicht vorteilhaft, dass die Stützfläche bzw. die Rückenlehne beim Sitzen in der ersten Endposition länger ausgebildet ist als beim Stehsitzen in der zweiten Endposition. Hierdurch weist die Stützfläche einen geringeren Hebelarm auf, sodass der Sitz- und Stützkorpus weniger stark belastet wird. Zudem kann die Rückenlehne so gebaut werden, dass sie die Norm DIN EN 1335-1:2002-08 bzgl. einer Mindesthöhe für eine Rückenlehne eines Bürostuhls erfüllt.This advantageously makes it possible for the support surface or the backrest to be made longer when sitting in the first end position than when standing still in the second end position. As a result, the support surface has a lower lever arm, so that the seat and support body is less heavily loaded. In addition, the backrest can be built to comply with the standard DIN EN 1335-1: 2002-08 regarding a minimum height for a backrest of an office chair.
Bevorzugt ist das Abdeckteil über eine Kinematik an den Sitz- und Stützkorpus gekoppelt, wobei die Betätigung der Kinematik an die Schwenkbewegung gekoppelt sein kann. Hierdurch ist es möglich, dass das Abdeckteil bei der Verschwenkung von der ersten Endposition in die zweite Endposition automatisch von seiner ausgefahrenen Stellung in eine eingefahrene Stellung verlagert wird. Als Kinematik kommt z.B. eine Viergelenkkinematik in Betracht.Preferably, the cover is coupled via a kinematics to the seat and support carcass, wherein the actuation of the kinematics may be coupled to the pivoting movement. This makes it possible that the cover is automatically shifted during pivoting from the first end position to the second end position of its extended position to a retracted position. As kinematics, for example, a four-joint kinematics is considered.
