Abstract

A stand mixer includes a column, a column rail mounted to the column and a bowl support mounted to the column rail such that the bowl support is vertically translatable along the column. A bowl is mounted to the bowl support. A fine adjustment apparatus is configured for adjusting a height of the bowl on the bowl support. The fine adjustment apparatus includes a cam rotatably mounted on the column. A cam tab on the column rail engages the cam. The cam and cam tab are configured such that the bowl support vertically translates in relation to the column as the cam rotates.

First claim

What is claimed is:

1 . A stand mixer, comprising:
a column; a column rail mounted to the column; a bowl support mounted to the column rail such that the bowl support is vertically translatable along the column; a bowl mounted to the bowl support; a fine adjustment apparatus configured for adjusting a height of the bowl on the bowl support; and a fastener slot configured for selectively fastening the fine adjustment apparatus in place, the fine adjustment apparatus comprising:
a cam rotatably mounted on the column, an end of the cam defining a cam head, and
an adjustment tab on the column rail and engaging the cam,
wherein the cam and cam tab are configured such that the bowl support vertically translates in relation to the column as the cam rotates.

2 . The stand mixer of claim 1 , wherein the bowl support is slidably mounted on the column.

3 . The stand mixer of claim 1 , wherein the fastener slot comprises at least one flexible fastener, wherein, when engaged, the flexible fastener provides tension between the bowl support and the column.

4 . The stand mixer of claim 1 , wherein the fastener slot comprises a locking pin, wherein engaging the locking pin in the fastener slot restrains movement of the fine adjustment apparatus.

5 . The stand mixer of claim 1 , further comprising a cam slot configured for selectively rotating the cam.

6 . The stand mixer of claim 5 , wherein the cam comprises a shaft affixed to the cam and the cam slot is positioned at an exterior of the column.

7 . The stand mixer of claim 6 , wherein the cam slot is one of a thumb screw, a dial, and a tool receiving orifice.

8 . The stand mixer of claim 1 , wherein the column rail provides a lower limit for the vertical translation of the bowl support.

9 . The stand mixer of claim 1 , further comprising a ramp block with a slot, and the ends of the slot delimit a traversable distance for the bowl support.

10 . The stand mixer of claim 4 , wherein the locking pin is rigid.

11 . A method for fine adjustment of a height of a bowl of a stand mixer, wherein the stand mixer comprises a column defining a vertical axis, a column rail, a bowl support mounted to the column rail, and a cam rotatably affixed to the column, the method comprising:
rotating the cam in order to traverse the bowl support to a desired height in relation to the column in a direction parallel to the vertical axis, and securing a fastener within a fastener slot to fasten the column rail in place along the direction parallel to the vertical axis.

12 . The method of claim 11 , wherein the fastener comprises at least one flexible fastener, wherein, when secured, the flexible fastener provides tension between the bowl support and the column.

13 . The method of claim 11 , wherein the fastener comprises a locking pin, wherein securing the locking pin in the fastener slot restrains movement of column rail.

14 . The method of claim 11 , wherein rotating the cam comprises rotating a cam slot.

15 . The method of claim 14 , wherein the cam comprises a shaft affixed to the cam and the cam slot is positioned at an exterior of the column.

16 . The method of claim 15 , wherein the cam slot is selected from the group consisting of a thumb screw, a dial, and a tool receiving orifice.

17 . The method of claim 11 , wherein the column rail defines a lower limit for translation of the bowl support.

18 . The method of claim 11 , wherein the stand mixer further comprises a ramp block with a slot, each end of the slot delimiting a traversable distance for the bowl support along the direction parallel to the vertical axis.

19 . A stand mixer, comprising:
a column; a column rail mounted to the column; a bowl support mounted to the column rail such that the bowl support is vertically translatable along the column; a bowl mounted to the bowl support; a ramp block with a slot, and the ends of the slot delimit a traversable distance for the bowl support; and a fine adjustment apparatus configured for adjusting a height of the bowl on the bowl support, the fine adjustment apparatus comprising:
a cam rotatably mounted on the column, an end of the cam defining a cam head, and
an adjustment tab on the column rail and engaging the cam,
wherein the cam and cam tab are configured such that the bowl support vertically translates in relation to the column as the cam rotates.

20 . The stand mixer of claim 19 , further comprising a cam slot configured for selectively rotating the cam.
