Abstract

A stand mixer includes a base with a support column, and a bowl lift framework extending outwardly from the support column. The bowl lift framework includes at least two lift arms. The lift arms are pivotable relative to the support column. A head is attached to an upper end of the support column and extends horizontally from the support column above the base. Additionally included is a bowl. The bowl includes a flange around a circumference of the bowl, and the bowl is held between the lift arms of the bowl lift framework.

First claim

What is claimed is:

1. A stand mixer, comprising:
a base;
a support column attached to the base and extending upwardly from the base;
a column rail mounted to the support column;
a bowl lift framework extending outwardly from the support column, the bowl lift framework comprising at least two lift arms and a bowl carrier slidably mounted on the column rail, the lift arms pivotable relative to the support column;
a hinge pin about which the lift arms are rotatably coupled to the bowl lift framework;
a ramp block mounted to the bowl carrier, wherein the ramp block defines a slot, wherein a ramp pin on an end portion of the lift arms is received within the slot of the ramp block, the ramp pin slidable between a first position and a second position within the slot;
a head attached to an upper end of the support column and extending from the support column above the base; and
a bowl,
wherein the bowl lift framework is configured for vertically moving the bowl relative to the head when the lift arm pivots relative to the support column, and the bowl is held between the lift arms of the bowl lift framework.

2. The stand mixer of claim 1 , wherein the bowl carrier comprises a mounting spike, a flange of the bowl configured for receiving the mounting spike of the bowl carrier in order to removeable mount the bowl on the bowl carrier.

3. The stand mixer of claim 1 , further comprising a locking spring, one end of the locking spring coupled to the bowl carrier and the other end of the locking spring coupled to the ramp pin, the locking spring in tension when the ramp pin is in the first position and the second position.

4. The stand mixer of claim 1 , wherein when actuated the bowl lift framework immobilizes the bowl in all directions.

5. The stand mixer of claim 1 , wherein the bowl lift framework is adjustable between a down position and an up position by pivoting the lift arm relative to the support column.

6. The stand mixer of claim 5 , wherein the bowl is positioned closer to the base in the down position than in the up position.

7. The stand mixer of claim 5 , wherein the bowl is suspended vertically over the base in the up position.

8. A stand mixer, comprising:
a base;
a support column attached to the base and extending upwardly from the base;
a column rail mounted to the support column;
a head attached to an upper end of the support column and extending from the support column above the base;
a bowl carrier slidably coupled to the column rail;
at least two lift arms rotatably mounted to the bowl carrier;
a ramp block mounted to the bowl carrier, wherein the ramp block comprises a slot and a ramp pin which couples the ramp block to the lift arms, wherein the ramp pin comprises a first position and a second position within the slot; and
a bowl comprising at least two flanges, the flanges positioned on opposite sides of the bowl,
wherein the bowl is removably mountable on the bowl carrier between the lift arms on the bowl carrier, and
wherein the flanges of the bowl and the bowl carrier are configured to removably couple.

9. The stand mixer of claim 8 , further comprising a hinge pin about which the lift arm is rotatably coupled to the bowl carrier.

10. The stand mixer of claim 8 , further comprising a locking spring, one end coupled to the bowl carrier and the other end coupled to the ramp pin, the locking spring in tension when the ramp pin is in the first position and the second position.

11. The stand mixer of claim 10 , wherein when the lift arm is actuated the bowl carrier immobilizes the bowl in all directions.

12. The stand mixer of claim 11 , further comprising two positions, a down position and an up position.

13. The stand mixer of claim 12 , wherein the bowl is positioned closer to the base in the down position than in the up position.

14. The stand mixer of claim 12 , wherein the lift arm is actuated, and the ramp pin is in a detent of the slot, the bowl is elevated vertically from the base of the stand mixer.

15. A stand mixer, comprising:
a base;
a support column attached to the base and extending upwardly from the base;
a column rail fixed to the support column;
a bowl lift framework extending outwardly from the column rail of the support column; and
a head attached to an upper end of the support column and extending horizontally from the support column above the base,
wherein the bowl lift framework further comprises,
a bowl carrier slidably coupled to the column rail;
at least two lift arms rotatably mounted to the bowl carrier, the lift arms rotatably coupled by a hinge pin; and
a bowl comprising at least two of a flange, the flange on opposing sides of the bowl, the bowl held between the lift arms on the bowl carrier, the flange of the bowl and the bowl carrier are configured to removably couple,
a ramp block mounted to the bowl carrier, the ramp block comprising a slot and a ramp pin which couples to the lift arms, the ramp pin comprises a first position and a second position within the slot, and
a locking spring, one end of the locking spring is coupled to the bowl carrier and the other end of the locking spring is coupled to the ramp pin, the locking spring is in tension when the ramp pin is in the first position and second position.

16. The stand mixer of claim 15 , wherein the stand mixer comprises two positions, a down position and an up position.
