Description
Vorrichtung zum Einstellen eines Sitzes, einer Tischplatte und dergleichen in verschiedene Höhenlagen. Gegenstand vorliegender Erfindung ist eine Vorrichtung zum Einstellen eines Sitzes, einer Tischplatte und dergleichen, in verschie dene Höhenlagen, wobei der Sitz, die Tisch platte und dergleichen eine Stütze aufweist, die verschiebbar in einem Träger von z. B. rundem oder eckigem Querschnitt angeordnet ist. Dabei ist die Stütze rohrförmig ausge bildet und sind in derselben mindestens ein Sperrkörper und, gegenüber der Stütze axial verstellbar, ein Widerlager angeordnet, derart, dass durch axiales Verstellen des Widerlagers ein Verschieben des Sperrkörpers in eine Klemmlage oder ein Freigeben des Sperr körpers stattfinden kann.
In der Zeichnung ist ein Ausführungs beispiel dargestellt, und zwar zeigt: Fig. 1 eine Vorderansicht eines Stuhles; Fig. 2 ist ein Längsschnitt durch Vor richtung; Fig.3 ist ein Schnitt nach der Linie 111-III der Fig. 2. Der gezeichnete Stuhl weist einen mit Fuss 1 versehenen rohrförmigen Träger 2 von rundem Querschnitt auf. In letzterem ist eine rohrförmige Stütze 3 verschiebbar angeordnet, die oben ein Sitzbrett 4 trägt. In der Stütze 3 sind in Querbohrungen 5 Kugeln 6 angeordnet, die gegen die Innen wandung des Rohres 2 anliegen und in Rasten 7 desselben eintreten können.
Die Kugeln 6 ruhen auf Stützflächen 8 eines Widerlagers 9 auf, das innerhalb der Stütze 3 axial verschiebbar angeordnet ist. Zum Verstellen des Widerlagers 9 dient eine Schiene<B>10,</B> welche durch eine Bohrung 11 des Widerlagers ragt und mittelst zweier als 11litnehmer dienender Querstiften 12 das Widerlager 9 mitnimmt. Die Schiene 10 steht unter der Wirkung einer Feder 13, die am untern Ende der Schiene 10 und an einem Stift 14 der Stütze 3 angreift; die Feder ist bestrebt, die Schiene 10 nach unten zu zie hen. Am obern Ende greift ein Zapfen 16 der Schiene 10 in einen schräg zur Axe des Rohres 3 gerichteten Schlitz 17.
Am Zapfen 16 greift eine Stange 18 an, die am einen Arm 19 eines Winkelhebels 20 angelenkt ist. Der Winkelhebel besitzt einen Handgriff 21 und ist auf der untern Seite des Sitzbrettes 4 drehbar so angeordnet, dass der Griff 21 leicht von Hand gefasst und verstellt werden kann. Wird der Griff 21 nach oben gedrückt so wird durch die Stange 18 der Zapfen 16 im Schlitz 17 schräg nach oben verstellt, und zwar- entgegen der Wirkung der Feder 13. Durch dieses axiale Verstellen der Stange 10 wird auch das Widerlager 9 axial ver schoben, so dass nun Aussparungen 22 des Widerlagers 9 gegenüber den Kugeln 6 zu stehen kommen.
Letztere treten aus den. Rasten 7 aus. Es kann die Stütze 3 im Trä ger 2 verschoben werden. Sobald aber der Griff 21 freigegeben wird, zieht die sich ent spannende Feder 13 das Widerlager 9 wieder nach unten und drückt mit dem Widerlager 9 die Kugeln 6 nach aussen. Letztere gleiten darin im Träger 2, bis sie in eine Rast 7 eintreten können. Hier findet dann eine Ver riegelung der Teile 2, 3 durch die Kugeln 6 statt, die aus ihrer. Sperrlage nicht selbst tätig austreten können.
Statt der Kugeln könnten auch andere Sperrkörper vorgesehen sein. Ferner kann auch das Widerlager 9 anders als gezeichnet ausgebildet werden, es können z. B. Stütze und Träger aus Vierkantröhren bestehen und die Sperrkörper könnten als bewegliche Backen ausgebildet werden usw.
Device for adjusting a seat, a table top and the like in different heights. The present invention is a device for adjusting a seat, a table top and the like, in different heights, wherein the seat, the table plate and the like has a support that is slidable in a support of z. B. is arranged round or angular cross-section. The support is tubular out and forms in the same at least one locking body and, relative to the support axially adjustable, an abutment arranged such that by axially adjusting the abutment, the locking body can be moved into a clamping position or the locking body can be released.
In the drawing, an embodiment is shown, for example, namely: Figure 1 is a front view of a chair; Fig. 2 is a longitudinal section through the device; FIG. 3 is a section along the line III-III in FIG. 2. The chair shown has a tubular support 2 provided with a foot 1 and having a round cross-section. In the latter, a tubular support 3 is slidably arranged, which carries a seat board 4 at the top. In the support 3 5 balls 6 are arranged in transverse bores, which abut against the inner wall of the tube 2 and can occur in notches 7 of the same.
The balls 6 rest on support surfaces 8 of an abutment 9 which is arranged axially displaceably within the support 3. To adjust the abutment 9, a rail <B> 10 </B> is used, which protrudes through a bore 11 of the abutment and takes the abutment 9 with it by means of two transverse pins 12 serving as drivers. The rail 10 is under the action of a spring 13 which acts on the lower end of the rail 10 and on a pin 14 of the support 3; the spring endeavors to pull the rail 10 downwards. At the upper end, a pin 16 of the rail 10 engages in a slot 17 directed obliquely to the axis of the tube 3.
A rod 18, which is articulated on one arm 19 of an angle lever 20, engages on the pin 16. The angle lever has a handle 21 and is rotatably arranged on the lower side of the seat board 4 so that the handle 21 can easily be grasped and adjusted by hand. If the handle 21 is pushed upwards, the pin 16 in the slot 17 is displaced obliquely upwards, against the action of the spring 13. By this axial displacement of the rod 10, the abutment 9 is also axially displaced, so that now recesses 22 of the abutment 9 come to stand opposite the balls 6.
The latter step out of the. Disengage 7. It can be the support 3 in Trä ger 2 moved. But as soon as the handle 21 is released, the ent tensioning spring 13 pulls the abutment 9 down again and presses the balls 6 with the abutment 9 to the outside. The latter slide therein in the carrier 2 until they can enter a detent 7. Here then a United locking of the parts 2, 3 takes place by the balls 6 from their. Not being able to actively exit the blocked position.
Instead of the balls, other locking bodies could also be provided. Furthermore, the abutment 9 can be designed differently than shown, it can, for. B. The support and beam are made of square tubes and the locking body could be designed as movable jaws, etc.
