Abstract
A blender arm includes a body equipped at one end with a connection for a power unit. The blender arm further includes a rotary shaft having a tool at the end opposite to the connection end. A peripheral protection is provided around the tool. The rotary shaft with the tool is attached movably in axial direction to the body so that the tool may be positioned in a retracted position for operation or a protracted position for cleaning, without having to touch the tool with the hands. The blender arm may further include a resilient element, functionally connected to the tubular body and the rotary shaft, for moving the rotary shaft between the protracted and retracted positions. When the rotary shaft is releases, the tool automatically returns to the retracted position.
Claims14
A blender arm comprising;
- a body equipped at a first end with a connection for connecting to a power unit;
- and
- a rotary shaft configured to rotate around an axis of the blender arm, the rotary shaft having a tool at a second end of the body opposite to the first end;
- wherein the rotary shaft with the tool is attached movably in an axial direction to the body so that the tool is movable in the axial direction relative to the body for changing a position of the rotary shaft relative to the body, and
- wherein the rotary shaft is functionally connected to an actuating element designed as part of the body for moving the rotary shaft in the axial direction from a retracted position where the tool is inside a peripheral protection to an extended position where the tool is outside the peripheral protection.

A blender arm comprising;
- a body equipped at a first end with a connection for connecting to a power unit;
- and
- a rotary shaft configured to rotate around an axis of the blender arm, the rotary shaft having a tool at a second end of the body opposite to the first end;
- wherein the rotary shaft with the tool is attached movably in an axial direction to the body so that the tool is movable in the axial direction relative to the body for changing a position of the rotary shaft relative to the body, and
- wherein the rotary shaft with the tool is attached movably in the axial direction to the body so that the tool returns automatically from an extended position where the tool is outside a peripheral protection to a retracted position where the tool is inside the peripheral protection.
