Abstract

A workstation for alternatively configuring a conventional desk for use while sitting and use while standing. The workstation includes an extendable column formed of multiple nested sections. The nested sections are configured to telescope such that the column can be extended. The workstation is configured to support a monitor and a tray. The extendable column contains a counter balance mechanism that is configured to resist collapsing of the column. A movement coupling mechanism is provided that it is such that motion of the first section relative to the second section is transmitted to the third section such that the third section moves a corresponding amount relative to the second section.

Claims

1. A workstation for alternatively configuring a conventional desk for use while sitting and use while standing, the workstation comprising:

an extendable column that includes nested sections that are nested together such that the column can telescope and there is a first section, a second section, and a third section positioned such that the first section is received by the second section and the second section is received by the third section;

a keyboard tray carried by the column and configured to support a keyboard; and

a movement coupling mechanism that is configured to couple at least two of the sections such that when one of the coupled sections moves relative to the remaining section, the other coupled section moves relative to the remaining section; and

wherein the movement coupling mechanism is configured to such that the first section and the third section are coupled;

wherein the first section is configured to move between a first position and a second position relative to the second section such that when the first section is in the first position, the column is collapsed and when the first section is in the section position, the column is extended;

wherein the third section is configured to move away from the first section when the first section moves from the first position to the second position;

an arm carried by the column and configured to support the keyboard tray;

a slidable work surface; and

wherein the slidable work surface is attached to the arm via structured positioned on the arm and the slidable work surface is configured to move along the arm between a first position and a second position such that when the slidable work surface is in the second position, the slidable work surface is positioned over at least a portion of the keyboard tray.

2. A workstation configured to be converted between being positioned for use from a sitting position and for being for use from a standing position, the workstation comprising:

an extendable column configured to receive a monitor, the column comprising;

a first section;

a second section configured to receive the first section; and

a third section configured to receive the second section;

a keyboard tray that is attached to the third section by an arm;

an auxiliary tray that defines a work surface that is configured to move between a first position along grooves formed in the arm such that the work surface is near the column and a second position such that the work surface is at least partially over the keyboard tray;

a strap that is connected at one end of the third section and at another end to a first section and configured to transfer motion from the first section and to the third section;

a rack defined in the second section;

a pin mechanically connected to the third section and configured to engage the rack;

a lever mechanically linked to the pin; and

wherein

the lever is configured to move the pin from a position in which the pin is engaged with the rack and a position in which the pin is clear of the rack and when the pin is clear of the rack, the first and third sections can move relative to the second section.

3. The workstation according to claim 2, wherein the lever is a lever biased to a neutral position that is between a first position and a second position and wherein the pin is engaged with the rack when the lever is in the neutral position and the pin is clear of the rack when the lever is in either of the first position or the second position.

4. The workstation according to claim 3, wherein the column is configured to support the monitor via a monitor mount.
