Abstract

A mobile workstation can include a head unit assembly. A worksurface can be coupled to the head unit assembly and configured to translate with respect to the head unit assembly between an open configuration and a closed configuration. A glide can be rotatably coupled to the head unit assembly and engaged with the worksurface. The glide can include a latch configured to translate with respect to a glide body of the glide. The mobile workstation can include a worksurface opening mechanism having a locking configuration and an unlocking configuration. The worksurface opening mechanism can include a latch release handle moveably coupled to the head unit assembly. Movement of the latch release handle can transition the worksurface opening mechanism between the locked configuration and the unlocked configuration. A release assembly can selectively engage with the first latch. A lift system can bias the worksurface away from the head unit assembly.

First claim

The claimed invention is:

1. A mobile workstation, comprising:
a height adjustable riser;
a head unit assembly coupled to the height adjustable riser; and
a display mount assembly including:
a display mount configured for attachment with a display;
a display riser; and
a display arm assembly extending between the display mount and the display riser and the display arm assembly is moveable between a first configuration and a second configuration, the display arm assembly comprising:
a first arm rotatably connected with the display riser at a first hinge;
a second arm rotatably connected with the first arm at a second hinge and rotatably connected with the display mount at a third hinge;
a third arm rotatably connected with the display riser at the first hinge; and
a fourth arm rotatably connected with the third arm at a fourth hinge and rotatably connected with the display mount at the third hinge;

wherein:
in the first configuration, the display mount is configured to hold the display in a first position facing a first direction; and
in the second configuration, the display mount is laterally offset relative to the first position and the display mount is rotationally offset relative to the first position to face a second direction.

2. The mobile workstation of claim 1 , wherein the first direction is rotationally offset by 90 degrees or more with respect to second direction.

3. The mobile workstation of claim 1 , wherein the display arm assembly is moveable between a contracted configuration and an expanded configuration, and wherein:
in the contracted configuration, the display mount is proximate to the display riser; and
in the expanded configuration, the display mount is remote from the display riser to change a distance between the display mount and the display riser.

4. The mobile workstation of claim 3 , wherein:
in the contracted configuration, the third hinge is proximate to the first hinge and the second hinge is remote from the fourth hinge; and
in the expanded configuration, the third hinge is remote from the first hinge and the second hinge is proximate the fourth hinge.

5. The mobile workstation of claim 1 , wherein:
the first hinge has a first rotational axis;
the second hinge has a second rotational axis;
the third hinge has a third rotational axis; and
the first rotational axis is parallel with the second rotational axis and the third rotational axis.

6. The mobile workstation of claim 5 , wherein the display mount includes a tilt mechanism configured to allow the display to rotate along a tilt rotational axis offset from at least the first rotational axis.

7. The mobile workstation of claim 1 , wherein the display arm assembly is moveable between a contracted configuration and an expanded configuration, and wherein:
in the contracted configuration, the third hinge is proximate to the first hinge; and
in the expanded configuration, the third hinge is remote from the first hinge to change a distance between the display mount and the display riser.

8. The mobile workstation of claim 1 , wherein the display riser includes a counterbalance mechanism configured to help change a height of the display arm assembly along the display riser.

9. A mobile workstation, comprising:
a height adjustable riser;
a head unit assembly coupled to the height adjustable riser, the head unit assembly including a worksurface; and
a display mount assembly including:
a display mount configured for attachment with a display;
a display riser coupled with the head unit assembly; and
a display arm assembly extending between the display mount and the display riser and the display arm assembly is moveable between a first configuration and a second configuration, the display arm assembly comprising:
a first arm rotatably connected with the display riser at a first hinge;
a second arm rotatably connected with the first arm at a second hinge and rotatably connected with the display mount at a third hinge;
a third arm rotatably connected with the display riser at the first hinge; and
a fourth arm rotatably connected with the third arm at a fourth hinge and rotatably connected with the display mount at the third hinge;

wherein:
in the first configuration, the display mount is configured to hold the display in a first position above the worksurface facing a first direction; and
in the second configuration, the display mount is laterally offset relative to the first position and the display mount is rotationally offset relative to the first position by at least 90 degrees to face a second direction.

10. The mobile workstation of claim 9 , wherein:
the first hinge has a first rotational axis;
the second hinge has a second rotational axis;
the third hinge has a third rotational axis; and
the first rotational axis is parallel with the second rotational axis and the third rotational axis.

11. The mobile workstation of claim 10 , wherein the display mount includes a tilt mechanism configured to allow the display to rotate along a tilt rotational axis offset from at least the first rotational axis.

12. The mobile workstation of claim 9 , wherein the display arm assembly is moveable between a contracted configuration and an expanded configuration, and wherein:
in the contracted configuration, the third hinge is proximate to the first hinge; and
in the expanded configuration, the third hinge is remote from the first hinge to change a distance between the display mount and the display riser.

13. The mobile workstation of claim 9 , wherein the display riser includes a counterbalance mechanism configured to help change a height of the display arm assembly along the display riser.

14. A mobile workstation, comprising:
a height adjustable riser;
a head unit assembly coupled to the height adjustable riser; and
a display mount assembly including:
a display mount configured for attachment with a display;
a display riser; and
a display arm assembly moveable between a first configuration and a second configuration, the display arm assembly including:
a first arm rotatably connected with the display riser at a first hinge;
a second arm rotatably connected with the first arm at a second hinge and rotatably connected with the display mount at a third hinge;
a third arm rotatably connected with the display riser at the first hinge; and
a fourth arm rotatably connected with the third arm at a fourth hinge and rotatably connected with the display mount at the third hinge;

wherein:
in the first configuration, the display mount is configured to hold the display in a first position facing a first direction with the third hinge proximate to the first hinge; and
in the second configuration, the display mount is laterally offset relative to the first position and the display mount is rotationally offset relative to the first position to face a second direction with the third hinge remote from the first hinge.

15. The mobile workstation of claim 14 , wherein the first direction is rotationally offset by 90 degrees or more with respect to the second direction.

16. The mobile workstation of claim 14 , wherein:
the first hinge has a first rotational axis;
the second hinge has a second rotational axis;
the third hinge has a third rotational axis; and
the first rotational axis is parallel with the second rotational axis and the third rotational axis.

17. The mobile workstation of claim 16 , wherein the display mount includes a tilt mechanism configured to allow the display to rotate along a tilt rotational axis offset from at least the
