摘要:
Es wird eine Antriebsvorrichtung (1) für ein Möbelteil mit einem Drehelement (8, 9) vorgeschlagen, das in der Antriebsvorrichtung um eine Drehachse (16) drehbar gelagert ist. Erfindungsgemäß ist in Richtung der Drehachse (16) ein Zwischenraum zwischen dem Drehelement (8, 9) und einem Gegenelement ausgebildet, wobei das Drehelement (8, 9) mit dem Gegenelement durch mindestens einen Faden (10, 11, 12, 13) verbunden ist, der entlang der Drehachse (16) im Zwischenraum geführt ist, wobei der Faden (10, 11, 12, 13) am Drehelement (8, 9) und am Gegenelement derart befestigt ist, dass der Faden (10, 11, 12, 13) durch eine Drehbewegung des Drehelements (8, 9) gegenüber dem Gegenelement mit einer Torsionskraft beaufschlagbar ist, mit der sich das Möbelteil bewegen lässt.
摘要:
Partial turn actuator comprising an output shaft (1), a first element (5) with a degree of freedom to translation, said element (5) being moved by a driving power, at least a second axially constrained element (2, 10, 11, 15), at least one of said elements having a degree of freedom to rotation according to which it is mechanically connected to the output shaft (1) and at least a rod (6, 7) constrained by means of a first hinge (8, 8') to the first element (5) and by means of a second hinge (9, 9') to the second axially constrained element (2, 10, 11, 15), so that the translation of the first element (5) is converted in a rotation of the element having a degree of freedom to rotation, and as a consequence, of the output shaft (1).
摘要:
An actuator device (10) includes a motor (12) and a reduction device (14) operatively coupled to the motor (12) and oriented about a central axis (20). The reduction device (14) is configured to modify an input angle of rotation provided by the motor (12) to an output angle of rotation. Further included is a rotary flexure mechanism (30) that includes a rotary flexure (32) operatively coupled to an output portion of the reduction device (14). The rotary flexure mechanism (30) also includes a plurality of flexure blades (36) coupled to the rotary flexure (32), each of the flexure blades (36) angularly oriented from the central axis (20). The rotary flexure mechanism (30) further includes a diaphragm flexure pair (40,44) operatively coupled to the flexure blades (36). The diaphragm flexure pair (40,44) comprises a rotational and in-plane stiffness greater than an axial stiffness resulting in the rotary flexure mechanism (30) being configured to convert a rotational input to an axial translation.
