FIELD

The disclosure generally relates to systems and methods for height adjustable desks.

BACKGROUND

Height adjustable worksurfaces and workstations can be used in sit-to- stand applications.

OVERVIEW

The present inventors recognized a need for a height adjustable device having a counterbalance mechanism or lifting mechanism with a thin width profile. The thin width profile of the counterbalance mechanism can allow a substantial portion of the device to be mounted within a wall or concealed behind a panel. Such a mounting can reduce the space required in a room or hallway where the height adjustable device can be used. This can be advantageous for installations of work-stations/display mounts in areas with minimum clearances (hospital hallways, operating or patient rooms, cruise ships, efficiency apartments, etc.). Concealing the lift mechanism counterbalance mechanism also can create a cleaner visual appearance by concealment of the device.

The height adjustable device can include a counterbalance mechanism

(also referred to as a lift mechanism in this disclosure) and a mounting member. The mounting member can be slidably coupled to the counterbalance mechanism to provide for a range of positions from a lowered position to a raised position. The counterbalance mechanism can include an energy' storage member that can support the weight of items attached to the mounting member, for example, a worksurface and/or display mount and display. The energy storage member can support the worksurface (e.g. with a computer on it) and allow a user to adjust the worksurface height with minimal effort. The counterbalance mechanism can be positioned on the inside of a wall surface, and can be configured to be concealed in a wall structure, such as a standard wall having a 3.5" depth or a thinner wall having a smaller depth, such as less than 3.5". The mounting member can protrude through the wall surface, into a room area.

A worksurface, such as a desk or table surface, can be coupled to the mounting member. The worksurface can provide space for a computer, a computer keyboard, documents, or provide any other desk/table functions. In some example implementations, a hinge in back of the worksurface can allow the worksurface to be folded when not in use.

A display mounting assembly can be directly attached to the mounting member or can be attached to the worksurface. The display' mounting assembly can be configured to hold one or more displays and can include display adjustment features. The display mounting assembly can include a mounting column that can also include a second counterbalance mechanism for providing height adjustability of the display mount.

The height adjustable device can be configured with a worksurface, with a display mount, or with both a worksurface and a display mount.

The height adjustable device can include a panel that can cover an opening in a wall formed for the placement of the counterbalance mechanism The panel can include one or more slots. The mounting members can extend from the counterbalance mechanism, through the slots and can protrude from the exterior side of the panel, into a room area. The panel can be removable for maintenance or adjustment of the counterbalance mechanism, or for installation purposes.

The counterbalance mechanism can include attachment members that can attach to an inner wall structure, such as to wall studs. The attachment members can be substantially perpendicular to a substantially vertical counterbalance mechanism

In addition, the present inventors recognized a need for a self-contained, collapsible, freestanding, mobile, double-sided, sit/stand workstation assembly. Examples of this workstation assembly can be used as a standalone workstation, or several workstations can be linked together to form a collaborative workspace. The workstation assembly can have various sizes, single-sided, dual- sided, 1, 2, or 4 independent worksurfaces.

Examples of this workstation assembly can be a piece of furniture mat can easily be converted from a compact, self-contained, highly mobile unit to an expanded, highly functional, height adjustable work space. This concept can be scaled from having a single stowed worksurface to any number of worksurfaces, for example, two, four, six or eight worksurfaces.

Deployment of legs of an example workstation assembly can be executed any number of ways, and in examples described below, legs are deployed in a horizontally and vertically rotating manner. The workstation assembly can include built in handles to aid in the movement of the unit, which can also include casters mounted to the underside. In an example, the workstation assembly can also include casters mounted at the end of each leg to enable movement of the workstation assembly after the legs are deployed.

The workstation assembly can also include accessory channels on the left, top, and right sides, which can be used for attaching privacy/distraction management panels, power systems, storage, accessory hooks, etc. In an example the accessory channels can also be used as a means of attaching adjacent workstation assembly units together, if desired. In an example, the legs can be deployed prior to deploying the worksurfaces. Such a deployment can prevent improper loading of a worksurface that is unsupported by a sufficiently sized base. As described below the legs can overlap the worksurface on the left and right sides. A workstation assembly can include a shallow depth of a lifting mechanism. This shallow depth can allow a substantial portion of the lifting mechanism to be mounted within a wall or concealed behind a panel. Such space saving/concealment reduces the space required in the room or hallway where the workstation assembly can be used. This can be beneficial for installations of workstation assemblies in areas requiring minimum clearances (hospital hallways, operating or patient rooms, cruise ships, efficiency apartments, etc.). Concealing at least a portion of the lift mechanism can also create a cleaner visual appearance of the workstation assembly.

Workstation assemblies can include a wheeled base. This can allow them to be moved around and create workspace for more than one person. The panels of the workstation assembly can also perform as a privacy panel.

DETAILED DESCRIPTION

FIG. 1 illustrates a side view of a height adjustable device 10, in accordance with at least one example of the present disclosure. FIG. 2 illustrates a front perspective view of a height adjustable device 10, in accordance with at least one example of the present disclosure. The height adjustable device 10 can include a vertical support member 1 1 , a counterbalance mechanism 12, a worksurface 13, a first opening 14A, a second opening 14B, a first mounting member 15 A, and a second mounting member 15B (see FIG. 2).

The vertical support member 11 can include a front portion 16A and a rear portion 16B. The rear portion 16B can oppose the front portion 16 A. In an example, the front and rear portions can be two opposing faces or main surfaces of a panel or wall. The vertical support member 11 can be a portion of a wall 17. In another example, the vertical support member 1 1 can include a panel 20, that can be coupled to or be a portion of the wall 17. In another example, the panel 20 can be part of a free standing device not associated with a wall 17.

In an example, a wall 17 can include an opening (not shown) such that the panel 20 can fit the opening and form a portion of the wall 17. In an example, the panel 20, wall 17, or vertical support member 11, can include a first vertical surface 18 A, and an opposing second vertical surface 18B. In an example, a second panel 20B can include a third vertical surface 18C, and an opposing fourth vertical surface 18D and as described below can include corresponding counterbalance mechanisms and/or worksurfaces.

The counterbalance mechanism 12 can be affixed adjacent to the rear portion 16B of the vertical support member 11. In an example, the

counterbalance mechanism 12 can be affixed adjacent to the second vertical surface 18B or other structural members of the vertical support member 11. The first and second openings 14 A, 14B are shown in FIG. 2 and can be vertically oriented slots that can allow the first and second mounting members 15A, 15B to extend through the vertical support member 11. The portion of the first and second mounting members 15 A, 15B mat extends to the rear portion 16B (FIG. 1), can be coupled to the counterbalance mechanism 12. The portion of the first and second mounting members 15 A, 15B that extends to the front portion 16A can support the worksurface 13. The first and second mounting members 15 A, 15B can be moveable along a portion of the length of the counterbalance mechanism 12.

Although the height adjustable device 10 is shown in FIG. 2 as having first and second openings 14A, 14B, and first and second mounting members 15 A, 15 A, any number of openings or mounting members can be used without changing the intent of the present disclosure. In an example one opening and one mounting member are used. In an example, more than two openings and more than two mounting members are used. In an example, the first and second mounting members 15A, 15B can be connected with a structural member or formed as one piece.

The counterbalance mechanism 12 can include an energy storage member such as a spring, a gas spring, or a resilient member that can provide a counteracting force 19 (FIG. 1) to any downward force 23 (FIG. 1) caused by the weight of the worksurface 13, a display mounting assembly 24, the first and second mounting member 15 A, 15B, or any additional weight applied to the worksurface 13, such as a computer, books, etc., or the weight of any displays attached to the display mounting assembly 24.

The counterbalance mechanism 12 can be adjustable to tailor the counteracting force 19 to apply to various configurations that can be used, and the counteracting force 19 can also provide a force to make raising the height adjustable device 10 easier. Any height adjustment of the worksurface 13 can be made with a minimal user effort. The counterbalance mechanism 12 can include wheels, pulleys, and tension members. The tension members can be ropes, cords, chains or cables.

The counterbalance mechanism 12 can be configured with a thin width profile 25 (FIG. 1) such that the counterbalance mechanism 12 can be located within a wall 17 (see also FIG. 3). The thin width profile 25 can be in the range of about 1 -6 inches. The thin width profile 25 can be in the range of about 2-5 inches. The thin width profile 25 can be in the range of about 3-4 inches. The thin width profile 25 can be in the range of about 3.5 inches.

The counterbalance mechanism 12 can be adjustable from either side of the panel 20. A wall structural member (e.g. wood or metal stud) width 89 can be greater man the thin width profile 25 or any combined width of the counterbalance mechanism 12 and the width of attachment members 26 A, 26B that may be coupled to the counterbalance mechanism 12. In an example, the width of the counterbalance mechanism 12 and any auxiliary attachment structures can be narrow enough such that the counterbalance mechanism 12 can be hidden within a wall 17 or panel 20 structure. The worksurface 13 can be coupled to or can rest against an upper surface 27 A, 27B of the mounting member 15 A, 15B. The worksurface 13 can be any size. Works urf aces 13 ft at are larger can be supported by more than one counterbalance mechanism Height adjustable devices 10 having more than one counterbalance mechanism connected to a worksurface 13, and each having at least one mounting member can be synchronized to raise and lower evenly.

The display mounting assembly 24 can include a column 28, a cross member 29, and one or more display mounts 30. The display mounting assembly 24 can be coupled to the worksurface 13. The display mount 30 can be configured to retain a video display, such as a VESA mount. The display mounting assembly 24 can include a cross member 29 that can allow more than one display mount 30 to be used. The display mounts 30 can be movably coupled to the cross member 29. A display (not pictured) can be coupled to the display mount 30. The column 28 can include a separate adjustable

counterbalance mechanism, to allow a height adjustment of the display mount 30 relative to a top of the worksurface 13. In an alternative example, the display mounting assembly 24 can be coupled to the mounting member 15 A, 15B.

The first and second openings 14 A, 14B can be a slot, an open track, a free space between two components, or any other type of aperture that can allow one or more mounting members to extend from one side of a wall or panel surface to the other side of the wall or panel surface. The first and second openings 14 A, 14B can extend vertically in the panel 20. The first and second openings 14 A, 14B can allow the mounting members 15 A, 15B (see FIG. 1) to slide upwardly and downwardly so that the height of the height adjustable device 10 can be changed.

In an example, the mounting members 15 A, 15B can be formed as shown with a triangular shaped configuration. In an alternative example, the mounting members 15 A, 15B can be rectangularly shaped, irregularly shaped, or have curved portions.
