Abstract
A quick release attachment assembly and system to releasably join a utensil to a stand mixer drivetrain. The system includes an assembly comprising one or more retaining balls to axially fix an attachment insert in the assembly and a plurality of cooperating walls to fix the attachment insert against rotational displacement.
Claims18
An attachment system for a stand mixer, the attachment system comprising:
- a ball and sleeve coupling mechanism movable between a loaded position and an unloaded position, the ball and sleeve coupling mechanism comprising a first retaining ball and a shield, wherein the shield supports the first retaining ball along a radial direction in the unloaded position;
- and
- an attachment insert comprising;
- a mating portion at a proximal end of the attachment insert along an axial direction, the mating portion defining a plurality of faces and a centrally located passage;
- and
- an insert portion at a distal end of the attachment insert along the axial direction, the insert portion including a receptacle;
- wherein the centrally located passage is configured to accept a post comprising a head, the head configured to slidably engage an interior wall of the centrally located passage,
- wherein:
- the first retaining ball moves inward along the radial direction and is received in the receptacle when the ball and sleeve coupling mechanism is in the loaded position.

A quick release attachment system for a stand mixer, the quick release attachment system comprising:
- an attachment assembly comprising:
- a body having a distal end with a shank portion and a proximal end with a receiving portion, the receiving portion including six cavity walls defining an insert receiving cavity, a first cavity wall having a first through hole formed therethrough and a second cavity wall having a second through hole formed therethrough;
- an outer retainer disposed around an outside surface of the receiving portion and supported for axial displacement;
- a shield arranged in the insert receiving cavity and supported for axial displacement between a first position and a second position distal to the first position;
- a first retaining ball received within the first through hole for displacement between an unloaded position and a loaded position;
- a second retaining ball received within the second through hole for displacement between an unloaded position and a loaded position;
- and
- an attachment insert comprising:
- a mating portion;
- and
- an insert portion including at least one receptacle;
- wherein:
- the attachment insert defines a centrally located passage;
- wherein the centrally located passage is configured to accept a post comprising a head, the head configured to slidably engage an interior wall of the centrally located passage,
- wherein the mating portion defines six faces,
- wherein the shield supports the first and second retaining balls along a radial direction in the unloaded position, and
- wherein the first and second retaining balls move radially inward to the loaded position and the first and second retaining balls are received in the at least one receptacle when the shield is in the second position.
