Description

Die Erfindung bezieht sich auf einen Stuhl, insbesondere Gartentsuhl, mit höhenverstellbarem Sitz an einem Kreuzgestell mit zwei Stützstrebenpaaren, welche jeweils im Bereich der vorderen bzw. hinteren Sitzkante am Sitz angreifen und um eine zu den Sitzkanten im wesentlichen parallele, mittlere Drehachse schwenkbar miteinander verbunden sind.The invention relates to a chair, in particular garden chair, with a height-adjustable seat on a cross frame with two pairs of support struts, each of which engages in the area of the front or rear edge of the seat on the seat and is pivotally connected to one another about a central axis of rotation which is essentially parallel to the seat edges .

Beispielsweise sind derartige Stühle bekannt, bei denen dasjenige Stützstrebenpaar des Kreuzgestells, welches im Bereich der hinteren Sitzkante am Sitz angreift, Teil der Rückenlehne des Stuhles ist, indem es von den beiden äußeren, bogenförmig gekrümmten Längsstreben der Rückenlehne gebildet wird, und zwar von deren sich unterhalb des Sitzes erstreckenden Abschnitten. Der Sitz ist an der hinteren Sitzkante um eine dazu im wesentlichen parallele Drehachse schwenkbar mit der Rückenlehne verbunden und mit zwei sich in Sitzlängsrichtung erstreckenden, einahder gegenüberliegenden Rastschlitzen versehen, in welche zwei seitliche, aufeinander ausgerichtete Raststifte am oberen, benachbarten Ende des anderen Stützstrebenpaares ragen. Die Rastschlitze sind jeweils kammförmig ausgebildet und mit mehreren in unterschiedlichen Abständen von der hinteren Sitzkante angeordneten Seitenschlitzen versehen, welche von der gemeinsamen mittleren Drehachse der beiden Stützstrebenpaare weg nach oben gerichtet sind und zur Aufnahme des benachbarten Taststiftes in der jeweiligen Höhenstellung des Sitzes dienen, welcher eine bestimmte Neigung der Rückenlehne zugeordnet ist, da deren Längsstreben unterhalb des Sitzes das eine Stützstrebenpaar bilden, wie erwähnt. Je tiefer der Sitz eingestellt wird, desto mehr ist die Rückenlehne nach hinten geneigt.For example, chairs of this type are known in which the pair of support struts of the cross frame which engages the seat in the region of the rear seat edge is part of the backrest of the chair, in that it is formed by the two outer, arcuately curved longitudinal struts of the backrest, namely by the latter sections extending below the seat. The seat is pivotally connected to the backrest at the rear edge of the seat about an essentially parallel axis of rotation and is provided with two latching slots which extend in the longitudinal direction of the seat and face each other and into which two lateral, aligned latching pins protrude at the upper, adjacent end of the other pair of support struts. The locking slots are each comb-shaped and with several at different intervals provided by the rear edge of the seat arranged side slots, which are directed away from the common central axis of rotation of the two pairs of support struts and serve to receive the adjacent stylus in the respective height position of the seat, which is assigned a certain inclination of the backrest, since their longitudinal struts below the Seat that form a pair of support struts, as mentioned. The lower the seat is adjusted, the more the backrest is tilted backwards.

Der Erfindung liegt die Aufgabe zugrunde, einen Stuhl, insbesondere Gartenstuhl, der eingangs angegebenen Gattung zu schaffen, bei welchem auf einfache Weise die Höhenverstellung des Sitzes verbessert ist, insbesondere störungsfrei und zuverlässig erfolgt, ohne daß der jeweilige Benutzer übermäßige Kraft aufwenden und komplizierte Bewegungen des Stuhles vornehmen müßte, wobei die Verrastung des Stuhles in der jeweils eingestellten Stellung möglichst auch noch optisch kontrollierbar und eine federnde Ausbildung des Stuhles möglich sein soll.The invention has for its object to provide a chair, in particular garden chair, of the type specified, in which the height adjustment of the seat is improved in a simple manner, in particular is trouble-free and reliable, without the respective user exerting excessive force and complicated movements of the Chair would have to take place, the locking of the chair in the respectively set position should also be visually controllable if possible and a resilient design of the chair should be possible.

Diese Aufgabe ist durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Stuhles sind in den-restlichen Patentansprüchen gekennzeichnet.This object is achieved by the features specified in the characterizing part of patent claim 1. Advantageous refinements of the chair according to the invention are characterized in the remaining claims.

Nachstehend ist eine Ausführungsform des erfindungsgemäßen Stuhles anhand der Zeichnung beispielsweise beschrieben. Darin zeigen, jeweils schematisch:

  • Fig. 1 eine Seitenansicht eines erfindungsgemäß ausgebildeten Gartenstuhls;
  • Fig. 2 die Ansicht von hinten des Gartenstuhls gemäß Fig. 1, nämlich die Ansicht in Richtung des Pfeiles II in Fig. 1; und
An embodiment of the chair according to the invention is described below with reference to the drawing, for example. Therein show, each schematically:
  • Figure 1 is a side view of a garden chair designed according to the invention.
  • FIG. 2 the rear view of the garden chair according to FIG. 1, namely the view in the direction of arrow II in FIG. 1; and

Fi. 3 den Längsschnitt entlang der Linie A - B in Fig. 2.Fi. 3 shows the longitudinal section along the line A - B in FIG. 2.

Der Gartenstuhl besteht im wesentlichen aus einem Sitz 1, einer Rückenlehne 2 und einem Kreuzgestell 3, welches es erlaubt, die Höhe des Sitzes 1 über der Standfläche zu verändern.The garden chair consists essentially of a seat 1, a backrest 2 and a cross frame 3, which allows the height of the seat 1 to be changed above the standing area.

Das Kreuzgestell 3 weist eine mittlere Drehachse 4 auf, welche im wesentlichen parallel zur vorderen Sitzkante 5 und zur hinteren Sitzkante 6 verläuft. Der Sitz 1 und die Rückenlehne 2 sind um eine zur mittleren Drehachse 4 parallele Drehachse 7 schwenkbar miteinander verbunden.The cross frame 3 has a central axis of rotation 4, which runs essentially parallel to the front seat edge 5 and the rear seat edge 6. The seat 1 and the backrest 2 are pivotally connected to one another about an axis of rotation 7 parallel to the central axis of rotation 4.

Gemäß Fig. 2 weist die Rückenlehne 2 vier zueinander parallele, im Abstand voneinander angeordnete Längsstreben 8 auf, welche am oberen Ende durch eine Querstrebe 9 miteinander verbunden sind und am unteren Ende auf einer Achse 10 sitzen. Auf dieser ist auch der Sitz 1 schwenkbar gelag-ert, so daß also die Achse 10 die erwähnte Drehachse 7 gemäß Fig. 1 definiert.2, the backrest 2 has four mutually parallel, spaced-apart longitudinal struts 8 which are connected to one another at the upper end by a cross strut 9 and are seated on an axis 10 at the lower end. The seat 1 is also pivotably mounted on this, so that the axis 10 thus defines the mentioned axis of rotation 7 according to FIG. 1.

Das Kreuzgestell 3 besteht aus zwei Stützstrebenpaaren 11 und 12, welche um die mittlere Drehachse 4 schwenkbar miteinander verbunden sind. Das Stützstrebenpaar 11 ist am oberen Ende im Bereich der vorderen Sitzkante 5 am Sitz 1 um eine zur mittleren Drehachse 4 parallele Drehachse 13 schwenkbar angelenkt. Das andere Stützstrebenpaar 12 erstreckt sich auf der dem Sitz 1 abgewandten Seite von der mittleren Drehachse 4 weg nach unten und ist mit einem Arm 14 zur rastenden Verbindung mit der Rückenlehne 2 versehen.The cross frame 3 consists of two pairs of support struts 11 and 12 which are pivotally connected to one another about the central axis of rotation 4. The support strut p aar 11 is pivoted at the upper end in the area of the front seat edge 5 on the seat 1 about an axis of rotation 13 parallel to the central axis of rotation 4. The other pair of support struts 12 extends downward on the side facing away from the seat 1 from the central axis of rotation 4 and is provided with an arm 14 for latching connection to the backrest 2.

Der Arm 14 ist als Metallbeschlag ausgebildet und von zwei zueinander parallelen Platten 15 sowie 16 gebildet, welche sich über die mittlere Drehachse 4 hinweg zwischen das zugehörige Stützstrebenpaar 12 mit einem breiteren Abschnitt 15' bzw. 16' erstrecken und damit am Stützstrebenpaar 12 befestigt sind.The arm 14 is designed as a metal fitting and is formed by two mutually parallel plates 15 and 16, which extend across the central axis of rotation 4 between the associated pair of support struts 12 with a wider section 15 ′ and 16 ′ and are thus fastened to the pair of support struts 12.

Im Bereich des schmaleren Armes 14, welcher sich in der Mitte zwischen den beiden zueinander parallelen Stützstreben 12 von der mittleren Drehachse 4 weg zum Sitz 1 und zur Rückenlehne 2 hin erstreckt, weisen die beiden Platten 15 und 16 einen größeren gegenseitigen Abstand auf, um einen Längsschlitz 17 zu bilden. Quer durch diesen hindurch erstreckt sich die Achse 10, welche die Rückenlehne 2 und den Sitz 1 um die Drehachse 7 schwenkbar miteinander verbindet.In the area of the narrower arm 14, which is in the middle extends between the two mutually parallel support struts 12 away from the central axis of rotation 4 towards the seat 1 and towards the backrest 2, the two plates 15 and 16 are at a greater mutual distance in order to form a longitudinal slot 17. Across this extends the axis 10 which connects the backrest 2 and the seat 1 to each other about the axis of rotation 7 pivotally.

Der Arm 14 ist mit dem freien Ende 14' an der Rückenlehne 2 in verschiedenen Abständen von der Achse 10 festlegbar. Dazu weist der Arm 14 am freien Ende 14' zwei seitliche, aufeinander ausgerichtete Raststifte 18 auf, und sind an den einander zugewandten Innenseiten der beiden mittleren Längsstreben 8 der Rückenlehne 2, zwischen welche der Arm 14 ragt, zwei aufeinander ausgerichtete Rastschlitze 19 vorgesehen, in welche die Raststifte 18 ragen. Wie besonders deutlich aus Fig. 3 hervorgeht, sind die sich in Rückenlehnunglängsrichtung erstreckenden Rastschlitze 19 jeweils kammförmig ausgebildet und mit mehreren in unterschiedlichen Abständen von der Achse 10 zwischen Rücklehne 2 und Sitz 1 angeordneten Seitenschlitzen 20 versehen, welche sich auf der dem Sitz 1 abgewandten Seite des jeweiligen Rastschlitzes 19 erstrecken und mit der Längsachse 21 der jeweiligen Längsstrebe 8 einen spitzen Winkel α einschließen. Im verrasteten Zustand greifen die beiden Raststifte 18 jeweils in zwei miteinander fluchtende Seitenschlitze 20 der beiden Rastschlitze 19 ein, um die Rückenlehne 2 abzustützen, welche hinsichtlich ihrer Neigung dadurch fixiert ist,da3 die Achse 10, welche sie mit dem Sitz 1 verbindet, im Längsschlitz 17 des Armes 14 geführt ist. Wie besonders deutlich aus Fig. 3 ersichtlich ist, ist der Arm 14 abgebogen. Durch entsprechende Wahl der Gestalt des Längsschlitzes 17 baw. des Verlaufs desselben ist es möglich, verschiedenen Höhen des Sitzes 1 beliebige Neigungen der Rückenlehne 2 zuzuordnen.The arm 14 can be fixed with the free end 14 'on the backrest 2 at different distances from the axis 10. For this purpose, the arm 14 at the free end 14 'has two lateral, aligned locking pins 18, and two aligned locking slots 19 are provided on the mutually facing inner sides of the two central longitudinal struts 8 of the backrest 2, between which the arm 14 projects which protrude the locking pins 18. As can be seen particularly clearly from FIG. 3, the latching slots 19 extending in the longitudinal direction of the backrest are each comb-shaped and provided with a plurality of side slots 20 which are arranged at different distances from the axis 10 between the backrest 2 and the seat 1 and which are located on the side facing away from the seat 1 of the respective locking slot 19 and include an acute angle α with the longitudinal axis 21 of the respective longitudinal strut 8. In the locked state, the two locking pins 18 each engage in two aligned side slots 20 of the two locking slots 19 in order to support the backrest 2, which is fixed in terms of its inclination by the axis 10, which connects it to the seat 1, in the longitudinal slot 17 of the arm 14 is guided. As can be seen particularly clearly from FIG. 3, the arm 14 is bent. By appropriate choice of the shape of the longitudinal slot 17 baw. the course of the same, it is possible to various heights of the seat 1 any inclinations of the Assign backrest 2.

Im dargestellten Fall nimmt der Sitz 1 die höchste Stellung ein, da die beiden Raststifte 18 des Armes 14 in die untersten Seitenschlitze 20 der Rastschlitze 19 eingreifen. Um den Sitz 1 tiefer zu stellen, also seinen Abstand von der Standfläche des Gartenstuhles zu verringern, genügt es, die Rückenlehne 2 geringfügig anzuheben, so daß die beiden Raststifte 18 des Armes 14 aus den beiden untersten Seitenschlitzen 20 der beiden Rastschlitze 19 an der Rückenlehne 2 herauslaufen, wonach die Rückenlehne 2 abgesenkt wird, bis der Sitz 1 die gewünschte Höhe einnimmt, woraufhin die beiden Raststifte 18 des Armes 14 in die beiden dann damit fluchtenden Seitenschlitze 20 der beiden Rastschlitze 19 der Rückenlehne 2 durch entsprechende Bewegung der letzteren eingeführt werden, um den Gartenstuhl in der neuen Stellung von Sitz 1 und Rückenlehne 2 zu halten.In the case shown, the seat 1 occupies the highest position, since the two locking pins 18 of the arm 14 engage in the lowermost side slots 20 of the locking slots 19. In order to lower the seat 1, i.e. to reduce its distance from the base of the garden chair, it is sufficient to raise the backrest 2 slightly, so that the two locking pins 18 of the arm 14 from the two lowest side slots 20 of the two locking slots 19 on the backrest 2 run out, after which the backrest 2 is lowered until the seat 1 assumes the desired height, whereupon the two locking pins 18 of the arm 14 are inserted into the two side slots 20 of the two locking slots 19 of the backrest 2, which are then flush therewith, by corresponding movement of the latter, to keep the garden chair in the new position of seat 1 and backrest 2.

Der Gartenstuhl ist sehr leicht und einfach zur Höhenverstellung des Sitzes 1 zu bedienen, wobei die zuverlässige gegenseitige Verrastung von Arm 14 und Rückenlehne 2 durch Inaugenscheinnahme kontrolliert werden kann. Die Stabilität und Standfestigkeit des Gartenstuhles sind ausgezeichnet.The garden chair is very light and easy to use to adjust the height of the seat 1, and the reliable mutual locking of arm 14 and backrest 2 can be checked by visual inspection. The stability and stability of the garden chair are excellent.

Wenn der Arm 14 aus Federstahl hergestellt wird, indem beispielsweise für die beiden Platten 15 und 16 Federstahlblech verwendet wird, dann ergibt sich im Verein mit der besonders deutlich aus Fig. 3 ersichtlichen, abgewinkelten Gestalt des Armes 14 eine ausgezeichnete Federwirkung, also Abfederung des Sitzes 1 und der Rückenlehne 2 gegenüber dem Kreuzgestell 3. Diese ohne Mehraufwand auf einfachste Weise zu verwirklichende federnde Ausbildung des Gartenstuhles erhöht den Sitzkomfort beträchtlich.If the arm 14 is made of spring steel, for example by using spring steel sheet for the two plates 15 and 16, then in conjunction with the angled shape of the arm 14 which can be seen particularly clearly from FIG. 3, there is an excellent spring action, i.e. cushioning of the seat 1 and the backrest 2 with respect to the cross frame 3. This resilient design of the garden chair, which can be implemented in the simplest way without additional effort, increases the seating comfort considerably.
