Definitions
- the invention relates to a height-adjustable table, in particular a desk, with at least one table base.
- table feet which are telescopically adjustable in height or in certain predetermined gradations.
- the innovation is based on the task of designing a table base with two vertical supports so that the vertical supports can be determined jointly and at the same time in certain height positions of the table which are dependent on the size of the operator.
- each table base comprises two vertical outer tubes connected to one another by a central web, in which inner tubes are guided telescopically, which can be locked together by means of a locking and clamping mechanism in different height positions relative to the outer tubes .
- the locking and clamping mechanism is preferably arranged in the region of the central web and comprises two locking and clamping pins, which are simultaneously secured outwardly in the direction of the outer and inner tubes by means of an actuating member and are secured against rotation, and whose conically tapering ends in Openings of the mutually opposing inner tubes can be inserted at a distance from one another.
- FIG. 1 shows a table, in particular a desk 1, with an upper table top 2 and one of two table feet 3.
- the individual table foot 3 consists of two outer tube elements 4 arranged at a lateral distance from one another, in which two inner tube elements 5 are guided telescopically.
- the two outer tubes 4 are connected to one another by a central web (not shown) which extends over part of the table foot height and thus form a rigid unit.
- Vertically extending veneers 6 are attached to the outer sides or the outer jacket surfaces of the outer tubes, of which only one veneer is shown in FIGS. 2 and 3.
- the inner tubes 5 extendable from the lower ends of the outer tubes 4 are fastened with their lower ends to a common, horizontally lying support 7. Between the two outer tubes 4, a locking and clamping mechanism is arranged essentially in the area of the central web between the two shields 6, the two locking means adjustable by means of an actuating element 8 simultaneously outwards in the direction of the outer and inner tubes 4, 5 Clamping pin 9 includes. These locking and clamping pins 9, which taper conically towards their ends, can be inserted into openings of the inner tubes 5, which are not numbered and shown in detail, and which are vertically spaced one above the other.
- two oppositely directed first threaded elements in the form of setscrews 10, 11 are arranged on the actuating element 8, preferably a knurled wheel, one of which has a right-hand thread and the other a left-hand thread.
- These two setscrews 10 and 11 interact with two complementary threaded elements in the form of threaded nuts or threaded sleeves 12 and 13, to which the two outward locking and clamping pins 9 are attached.
- the two threaded sleeves 12 and 13, which are secured against rotation, can simultaneously be extended outwards into the corresponding openings of the inner tubes 5, while by turning the knurled wheel in the opposite direction, the two locking and clamping pins 9 follow can be drawn in until the inner tubes can be adjusted relative to the outer tubes.
- the inner and outer tubes preferably have guide elements which prevent these two elements from rotating relative to one another.
- the outer and inner tubes have, for example, a hexagonal cross section.
Abstract
Description
Die Erfindung betrifft einen höhenverstellbaren Tisch, insbesondere Schreibtisch, mit mindestens einem Tischfuß.The invention relates to a height-adjustable table, in particular a desk, with at least one table base.
Bei Tischen, insbesondere Schreibtischen, ist es aus ergonomischen Gründen wünschenswert, die Tischhöhe an die Körpergröße der an dem Tisch arbeitenden Person anzupassen. Zu diesem Zweck ist es üblich, zum Beispiel stufenlos oder in bestimmten vorgegebenen Abstufungen in ihrer Höhe teleskopartig verstellbare Tischfüsse zu verwenden.In the case of tables, in particular desks, it is desirable for ergonomic reasons to adapt the table height to the body size of the person working on the table. For this purpose, it is customary, for example, to use table feet which are telescopically adjustable in height or in certain predetermined gradations.
Der Neuerung liegt die Aufgabe zugrunde, einen Tischfuß mit zwei Vertikalstützen so zu gestalten, daß die Vertikalstützen gemeinsam und gleichzeitig in bestimmten, von der Größe der Bedienungsperson abhängigen Höhenstellungen des Tisches feststellbar sind.The innovation is based on the task of designing a table base with two vertical supports so that the vertical supports can be determined jointly and at the same time in certain height positions of the table which are dependent on the size of the operator.
Zur Lösung dieser Aufgabe ist der erfindungsgemäße höhenverstellbare Tisch dadurch gekennzeichnet, daß jeder Tischfuß zwei durch einen Mittelsteg miteinander verbundene, vertikale Außenrohre umfaßt, in denen Innenrohre teleskopartig geführt sind, die gemeinsam mittels eines Arretier- und Klemmechanismus in unterschiedlichen Höhenstellungen relativ zu den Außenrohren feststellbar sind. Der Arretier- und Klemmechanismus ist vorzugsweise im Bereich des Mittelsteges angeordnet und umfaßt zwei mittels eines Betätigungsorganes gleichzeitig nach außen in Richtung der Außen- und Innenrohre verstellbare Arretier- und Klemmzapfen, die gegen Drehung gesichert sind, und deren sich nach außen konisch verjüngende Enden in im Abstand voneinander liegende Öffnungen der sich gegenüberstehenden Innenrohre einschiebbar sind.To achieve this object, the height-adjustable table according to the invention is characterized in that each table base comprises two vertical outer tubes connected to one another by a central web, in which inner tubes are guided telescopically, which can be locked together by means of a locking and clamping mechanism in different height positions relative to the outer tubes . The locking and clamping mechanism is preferably arranged in the region of the central web and comprises two locking and clamping pins, which are simultaneously secured outwardly in the direction of the outer and inner tubes by means of an actuating member and are secured against rotation, and whose conically tapering ends in Openings of the mutually opposing inner tubes can be inserted at a distance from one another.
Der erfindungsgemäße Tisch wird im folgenden anhand der Zeichnung näher beschrieben.
Figur 1 zeigt in isometrischer Darstellung eine Teilansicht des erfindungsgemäßen Tischs mit zugeordnetem Tischfuß;Figur 2 zeigt eine Schnittansicht entsprechend der Linie II-II des Tischfusses mit relativ zueinander arretierten und festgeklemmten Tischfußelementen;Figur 3 zeigt eine Schnittansicht entsprechend der Linie II-II inFigur 1 in dem Zustand der einzelnen Tischfußelemente während der Verstellung der Tischfußelemente relativ zueinander.
- Figure 1 shows an isometric view of a partial view of the table according to the invention with an associated table base;
- Figure 2 shows a sectional view along the line II-II of the table base with the table base elements locked and clamped relative to each other;
- Figure 3 shows a sectional view along the line II-II in Figure 1 in the state of the individual table base elements during the adjustment of the table base elements relative to each other.
Figur 1 zeigt einen Tisch, insbesondere Schreibtisch 1, mit einer oberen Tischplatte 2 und einem von zwei Tischfüssen 3. Der einzelne Tischfuß 3 besteht aus zwei in seitlichem Abstand voneinander angeordneten Außenrohrelementen 4, in denen zwei Innenrohrelemente 5 teleskopartig geführt sind. Die beiden Außenrohre 4 sind durch einen sich über einen Teil der Tischfußhöhe erstreckenden nicht dargestellten Mittelsteg miteinander verbunden und bilden somit eine starre Einheit. An die Außenseiten beziehungsweise die Außenmantelflächen der Außenrohre sind sich vertikal erstreckende Verblendungen 6 angesetzt, von den in den Figuren 2 und 3 nur jeweils eine Verblendung dargestellt ist.FIG. 1 shows a table, in particular a
Die aus den unteren Enden der Außenrohre 4 ausfahrbaren Innenrohre 5 sind mit ihren unteren Enden an einer gemeinsamen, horizontal liegenden Abstützung 7 befestigt. Zwischen den beiden Außenrohren 4 ist im wesentlichen im Bereich des Mittelsteges zwischen den beiden Abblendungen 6 ein Arretier- und Klemmechanismus angeordnet, der zwei mittels eines Betätigungsorganes 8 gleichzeitig nach außen in Richtung der Außen- und Innenrohre 4, 5 verstellbare Arretier- und Klemmzapfen 9 umfaßt. Diese sich zu ihren Enden hin konisch verjüngenden Arretier- und Klemmzapfen 9 sind in im einzelnen nicht bezifferte und dargestellte, im vertikalen Abstand übereinanderliegende Öffnungen der Innenrohre 5 einschiebbar. Zu diesem Zweck sind an dem Betätigungsorgan 8, vorzugsweise einem Rändelrad, zwei entgegengesetzt gerichtete erste Gewindeelemente in Form von Gewindestiften 10, 11 angeordnet, von denen der eine ein Rechtsgewinde und der andere ein Linksgewinde aufweist. Diese beiden Gewindestifte 10 bzw. 11 wirken mit zwei komplementären Gewindeelementen in Form von Gewindemuttern oder Gewindehülsen 12 bzw. 13 zusammen, an denen die beiden nach außen gerichteten Arretier- und Klemmzapfen 9 angebracht sind. Durch Drehen des Rändelrades 8 in der einen Richtung können die beiden gegen Drehung gesicherten Gewindehülsen 12 bzw. 13 gleichzeitig nach außen in die entsprechenden Öffnungen der Innenrohre 5 ausgefahren werden, während durch Drehen des Rändelrades in der entgegengesetzten Richtung die beiden Arretier- und Klemmzapfen 9 nach innen solange eingezogen werden können, bis die Innenrohre relativ zu den Außenrohren verstellt werden können.The
Die Innen- und Außenrohre weisen vorzugsweise Führungselemente auf, die eine Drehung dieser beiden Elemente relativ zueinander verhindern. Gemäß der zeichnerischen Darstellung haben die Außen- und Innenrohre beispielsweise einen sechseckigen Querschnitte.The inner and outer tubes preferably have guide elements which prevent these two elements from rotating relative to one another. According to the drawing, the outer and inner tubes have, for example, a hexagonal cross section.
