Title (EN) SELF-CENTERING SPRING RETURN MECHANISM FOR AN APPLIANCE KNOB
(FR) MÉCANISME DE RAPPEL PAR RESSORT À CENTRAGE AUTOMATIQUE POUR UN BOUTON D'APPAREIL
Abstract:
(EN) A self-centering knob assembly (104) comprising a back disk (202), a pair of rotary arms (204), a spring (206), and a circuit board (208) fixed to the knob shaft (106), is provided, with the pair of rotary arms (204) and spring (206) disposed between the back disk (202) and circuit board (208). Each rotary arm (204A, 204B) defines first and second slots (402A, 402B) at opposing ends and a center aperture (404) therebetween that rotatably engages the knob shaft (106). The first slot (402A) engages the end stop pin (302) to limit rotation of the rotary arm (204). The spring (206) defines opposing arms (502A, 502B) that engage and oppose rotation of respective rotary arms (204A, 204B) of the pair. The circuit board (208) includes circuitry configured to provide positioning data of the knob shaft (106), and including a drive pin (602) that, for each rotary arm (204A, 204B), engages and carries the second slot (402B) in a respective direction of an opposing direction when the knob shaft (106) and thereby the circuit board (208) is rotated in the respective direction.
(FR) La présente invention concerne un ensemble bouton à centrage automatique (104) qui comprend un disque arrière (202), une paire de bras rotatifs (204), un ressort (206) et une carte de circuit imprimé (208) fixée à un arbre de bouton (106), la paire de bras rotatifs (204) et le ressort (206) étant disposés entre le disque arrière (202) et la carte de circuit imprimé (208). Chaque bras rotatif (204A, 204B) possède des première et seconde fentes (402A, 402B) à des extrémités opposées, et une ouverture centrale (404) entre celles-ci qui entre en prise de manière rotative avec l'arbre de bouton (106). La première fente (402A) entre en prise avec une broche d'arrêt d'extrémité (302) pour limiter la rotation du bras rotatif (204). Le ressort (206) possède des bras opposés (502A, 502B) qui entrent en prise et s'opposent à la rotation de bras rotatifs (204A, 204B) respectifs de la paire. La carte de circuit imprimé (208) inclut un ensemble de circuits conçu pour fournir des données de positionnement de cet arbre de bouton (106), et elle comprend une broche d'entraînement (602) qui, pour chaque bras rotatif (204A, 204B), entre en prise avec la seconde fente (402B) et la porte dans une direction respective d'une direction opposée lorsque ledit arbre de bouton (106) et par conséquent la carte de circuit imprimé (208) tournent dans la direction respective.
