Abstract
An apparatus comprising a drive motor (7) with a shaft (8) having a front end for engaging a coupling device (20) for a whisk (10), and a rear end for engaging a drive (28) housed in a cylindrical body (31) and engageable by a mixing arm, as well as a vertically movable ejector member (51) linked to the coupling device. A movable mechanical assembly (70) is provided for releasing the ejector member (51) while blocking the internal space (74) in the body (31) so that only the whisk can be fitted, or alternatively locking the ejector member (51) in the down position while unblocking the internal space (74) in the body so that only the mixing arm can be fitted.
Claims5
A hand-held electrical beater-mixer comprising:
- a body (2) of generally prismatic shape;
- an electric drive motor (7), with a shaft (8), contained within said body (2) and disposed horizontally in a lower portion (12) of said body (2) when said beater-mixer is in its normal use position with a beating accessory (10);
- a rotatable coupling device (20) of the beating accessory (10) positioned in a forward portion (18) of said body (2) and opening through a base (22) of said body (2), said rotatable coupling device (20) being operatively connected to a forward end (14) of said shaft (8);
- a rotatable drive (28) carried by a rear end (26) of said shaft (8) and disposed within a cylindrical socket (31) extending horizontally in a rear portion (35) of said body (2), said cylindrical socket (31) comprising a passage (74) facing an opening (34) in a rear wall (35) of said body (2), said rotatable drive (28) being adapted to secure a mixing accessory (38) having a shaft end (39) adapted for coupling with said rotatable drive (28), and said opening (34) being adapted for the transit of the mixing accessory (38) into said passage (74);
- an ejection member (51) arranged vertically above and in communication with said rotatable coupling device (20), said ejection member (51) being displaceable in height from a lowered position to an upper position under the action of engaging the beating accessory (10) into said rotatable coupling device (20);
- a manual control member (61) operatively connected to said ejection member (51) so that action of said manual control member (61) moves said ejection member (51) from the upper position to the lower position, the movement of said ejection member (51) from the upper to the lower position disengaging the beating accessory (10) from said rotatable coupling device (20);
- a mechanical movable means (70) located within said body (2) and operatively connected to a resilient return means (72), said ejection member (51), and said passage (74) so as to block said passage (74) and preclude the coupling of the mixing accessory (38) with said rotatable drive (28) when said ejection member (51) engages the beating accessory (10), and so as to block said resilient return means (72) against said ejection member (51) so as to preclude the engagement of the accessory (10) with said rotatable coupling device (20) when coupling the mixing accessory (38) with said rotatable drive (28) interior to said socket (31) such that said mechanical movable means permits only one of the mixing accessory (38) and the beating accessory (10) to be used with said beater mixer.
