Abstract

Die Erfindung betrifft einen höhenverstellbaren Hocker (10) mit einem Fuß (12) zum Aufstellen auf einen Boden, mit einem eine oberseitige Sitzfläche (18) aufweisenden Sitzteil (16) und mit einem den Fuß (12) und das Sitzteil (16) verbindenden Verbindungsteil (20), wobei das Verbindungsteil (20) ein Außenrohr (22) und ein verschieblich im Außenrohr (22) aufgenommenes Innenrohr (24) aufweist, wobei entweder das Außenrohr (22) fest mit dem Fuß (12) und das Innenrohr (24) fest mit dem Sitzteil (16) oder das Außenrohr (22) fest mit dem Sitzteil (16) und das Innenrohr (24) fest mit dem Fuß (12) verbunden ist, und mit einem Arretiermechanismus (28) zum lösbaren Arretieren des Innenrohrs (24) am Außenrohr (22) in mehreren, unterschiedliche Abstände des Sitzteils (16) vom Fuß (12) definierenden Positionen. Erfindungsgemäß ist vorgesehen, dass der Arretiermechanismus (28) einen um eine Schwenkachse (32) verschwenkbar am Außenrohr (22) angelenkten zweiarmigen Arretierhebel (30a) aufweist, der am freien Ende (36) seines ersten Hebelarms (34) einen Haken (38) aufweist und dessen zweiter Hebelarm (40) ausgehend von der Schwenkachse (32) schräg nach außen absteht und gegen die Kraft einer Rückstellfeder radial nach innen verschwenkbar ist, und dass das Innenrohr (24) eine Anzahl von im Abstand zueinander in einer Reihe angeordneten Eingriffsöffnungen (42a) für den Haken (38) aufweist.The invention relates to a height-adjustable stool (10) with a foot (12) for placing on a floor, with a seat part (16) having an upper seat surface (18) and with a connecting part connecting the foot (12) and the seat part (16). (20), wherein the connecting part (20) has an outer tube (22) and an inner tube (24) which is displaceably accommodated in the outer tube (22), with either the outer tube (22) being fixed to the foot (12) and the inner tube (24) is firmly connected to the seat part (16) or the outer tube (22) is firmly connected to the seat part (16) and the inner tube (24) is firmly connected to the foot (12), and with a locking mechanism (28) for releasably locking the inner tube (24 ) on the outer tube (22) in several positions defining different distances between the seat part (16) and the foot (12). According to the invention, the locking mechanism (28) has a two-armed locking lever (30a) which is pivotably connected to the outer tube (22) about a pivot axis (32) and which has a hook (38) at the free end (36) of its first lever arm (34). and its second lever arm (40) projects obliquely outwards from the pivot axis (32) and can be pivoted radially inwards against the force of a return spring, and that the inner tube (24) has a number of engagement openings (42a) arranged at a distance from one another in a row ) for the hook (38).
