Abstract
In food-mixing apparatus comprising a driving unit and an arm, a latching and pivoting mechanism is adapted to be latched automatically so as to prevent relative movement of the arm and a console of the driving unit upon pivotal movement of the arm either to a lowered position or a raised position, and so as to prevent relative movement of the arm and the console, except for pivotal movement of the arm, upon pivotal movement of the arm to a pivotal position therebetween. The mechanism is adapted to be unlatched manually so as to permit pivotal movement of the arm from any pivotal position, and so as to permit the arm to be removed from the console upon further movement of the arm from the raised position.
Claims16
In a food-mixing apparatus comprising
- (a) a console, which has a transverse portion and an upright portion,
- (b) a mixing bowl, which is supported on the transverse portion,
- (c) a motor, which is mounted in the console,
- (d) an arm, which is mounted pivotally to the upright portion, for pivotal movement through positions including a lowered position, wherein the arm extends transversely over the mixing bowl supported on the transverse portion, and a raised position,
- (e) a mixing tool, which is mounted operatively to the arm,
- (f) a power train, which is carried by the arm so as to be coupled to the mixing tool mounted operatively to the arm, and
- (g) a coupler, which is driven by the motor, and which cooperates with the power train so as to couple the motor to the power train upon pivotal movement of the arm to the lowered position, and so as to uncouple the motor from the power train upon pivotal movement of the arm from the lowered position,
- an improvement wherein the apparatus comprises
- (h) a latching and pivoting mechanism, which connects the arm to the console, which comprises a first means latching automatically so as to prevent relative movement of the arm and the console, until the first means is unlatched, upon pivotal movement of the arm either to the lowered position or to the raised position, and so as to prevent relative movement of the arm and the console except for pivotal movement of the arm, until the first means is unlatched, upon pivotal movement of the arm to a pivotal position between the lowered position and the raised position, and which comprises a second means being arranged to be actuated manually and unlatching the first means when actuated manually so as to permit pivotal movement of the arm from any pivotal position, and so as to permit the arm to be removed from the console upon further movement of the arm from the raised position, in a sense opposite to pivotal movement of the arm from the raised position toward the lowered position.
