Title
(DE) ANTRIEB FÜR EINEN ROTIERENDEN GEGENSTAND, WIE EINE WALZE, WELLE, PLATTE ODER DERGLEICHEN
(EN) DRIVE MECHANISM FOR A ROTATING OBJECT SUCH AS A ROLLER, SHAFT, DISK OR SUCH LIKE
(FR) ENTRAINEMENT POUR UN OBJET TOURNANT, TEL QU'UN CYLINDRE, UN ARBRE, UN DISQUE OU ANALOGUE
Abstract
(DE)
Es wird ein Antrieb für einen rotierenden Gegenstand wie eine Walze, Welle, Platte oder dergleichen, insbesondere für einen Duftverdunster, einen Luftbefeuchter oder ein Luftreinigungsgerät oder dergleichen vorgeschlagen, der die folgenden Merkmale aufweist: einen beweglich gelagerten Hebel (9, 10), ein Zahnrad (8), das drehfest mit dem rotierenden Gegenstand (1) verbunden ist sowie ein Hebelgetriebe (7) für eine in das Zahnrad (8) eingreifende mitnehmende Bewegung des Hebels (9, 10) zur Drehung des Zahnrads (8), wobei der Hebel zum Eingriff in die Zähne (22) des Zahnrades eine Spitze (11, 12) aufweist. Erfindungsgemäß ist die Spitze (11, 12) in Form eines Zahnes ausgebildet, wobei die Form dieses Zahnes und die Zähne (22) des Zahnrades (8) sowie das Hebelgetriebe (7) derart aufeinander abgestimmt sind, daß die Zahnflanken des Zahnes (11, 12) am wenigstens einen Hebel (9, 10) und des jeweils im Eingriff stehenden Zahnes (22) am Zahnrad (8) bei der mitnehmenden Bewegung aufeinander abwälzen.
(EN)
The invention relates to a drive mechanism for a rotating object such as a roller, shaft, disk or such like, used notably for a fragrance vaporizer, humidifier, air purifier or such like. The drive mechanism is characterized in that it comprises a movably mounted lever (9, 10), a gear wheel (9) which is connected in a non-rotating manner to the rotating object (1) and a lever drive (7) for moving the lever (9, 10) such that it engages and rotates the gear wheel (8). To engage the teeth (22) of the gear wheel the lever has a tip (11, 12). According to the invention said tip (11, 12) has the shape of a tooth and the shape of said tooth and the teeth (22) of the gear wheel (8) as well as the lever drive (7) are configured such that the tooth flanks of the tooth (11, 12) of the at least one lever (9, 10) and the tooth flanks of the gear wheel (8) tooth (22) engaged at any one time roll off on each other during the driving movement.
(FR)
L'invention concerne un entraînement pour un objet tournant tel qu'un cylindre, un arbre, un disque ou analogue, destiné en particulier à un évaporateur de parfum, à un humidificateur d'air ou à un appareil de purification d'air ou analogue qui présente les éléments caractéristiques suivants: un levier (9, 10) monté mobile, une roue dentée (8) qui est solidaire en rotation de l'objet (1) tournant, et un engrenage à levier (7) servant à produire un mouvement d'engagement du levier (9, 10) dans la roue dentée (8) pour entraîner celle-ci en rotation, ledit levier étant pourvu, pour son engagement dans les dents (22) de la roue dentée, d'une pointe (11, 12). Selon l'invention, la pointe (11, 12) est formée par une dent, la forme de cette dent, la forme des dents (22) de la roue dentée (8) et la forme de l'engrenage à levier (7) étant adaptées l'une à l'autre pour que les flancs de la dent (11, 12) du ou des leviers (9, 10) et ceux de la dent (22) de la roue dentée (8) respectivement en prise passent les uns sur les autres pendant le déplacement d'entraînement.
