Motorized, height adjustable desktop system

Patent No. US10413055 (titled "Motorized, height adjustable desktop system") on Jul 6, 2017. The application was issued on Sep 17, 2019.

What is this patent about?

’055 is related to the field of ergonomic computer furniture, specifically height-adjustable workstations. The background context involves the transition from traditional static desks to standing desk converters that allow users to alternate between sitting and standing positions to alleviate health issues like back pain. While manual spring-assisted converters exist, they often require significant physical effort to lift heavy computer equipment, creating a need for a more effortless, automated solution.

The underlying idea behind ’055 is the integration of a linear actuator within a compact scissor-lift frame to provide motorized vertical adjustment for a desktop converter. By utilizing a motor-driven carrier bracket that slides along a track, the system converts horizontal force into vertical displacement through a set of intersecting arms. This mechanical arrangement allows for a high weight capacity and smooth elevation without the user having to manually hoist the weight of monitors and peripherals.

The claims of ’055 focus on a motorized desktop stand unit featuring a dual-surface design where a secondary keyboard tray is slideably attached in parallel to the main monitor surface. The independent claim specifically defines an elevation mechanism consisting of two pairs of scissor arms joined in an X-shaped arrangement that is oriented transversely—from left to right—relative to the user. This structure is controlled by a switch integrated directly into the main surface, which triggers the height adjustment between the upper and lower frames.

In practice, the invention functions as a sit-stand converter that sits atop an existing desk. The scissor assembly utilizes roller wheels that travel within U-shaped tracks in the lower frame, ensuring stability as the motor expands or contracts the X-shaped arms. To manage the transition between heights, the unit incorporates a coiled power cord to prevent tangling and includes specialized grommet assemblies that can either sit flush for cable routing or serve as mounting points for monitor arms.

The ’055 design differentiates itself from prior art by replacing manual lifting and locking pins with a motorized elevation mechanism that can lift up to 80 pounds at the touch of a button. Unlike standard desks, the slideable keyboard tray moves perpendicularly to the sides of the main surface, allowing for depth adjustment of the workspace. Furthermore, the transverse orientation of the scissor arms provides a stable, balanced lift that minimizes the lateral wobble often found in cantilevered or spring-loaded manual standing desk converters.

How does this patent fit in bigger picture?

Technical Landscape

In the mid-2010s when ’055 was filed, height-adjustable workstations were typically implemented using manual spring-assisted lift mechanisms or counterbalanced tension systems. At a time when ergonomic furniture commonly relied on physical user force to overcome the weight of mounted hardware, the integration of mechanical lift components often required significant manual effort to initiate and control vertical movement. Hardware constraints related to the weight distribution of monitors and peripherals made achieving smooth, incremental height transitions non-trivial without complex mechanical locking assemblies or high-tension manual actuators.

Prosecution Position

The technical advancement involves an architectural shift from manual, tension-based lift systems to a motorized elevation mechanism integrated within a multi-tier desktop converter frame. By incorporating a motorized actuator between an upper and lower frame assembly controlled by a surface-mounted switch, the system overcomes the physical constraints of lifting heavy computer equipment manually. This configuration enables precise, effortless vertical adjustment of both a main monitor surface and a secondary keyboard surface simultaneously, achieving a stable transition between sitting and standing heights while maintaining the relative alignment of the user interface components.

Claims

The patent contains a total of 6 claims, with claim 1 serving as the sole independent claim. This independent claim focuses on a motorized desktop stand unit featuring a main surface assembly, a slideable secondary surface, and an elevation mechanism utilizing an x-shaped scissor arm arrangement controlled by a switch to adjust the height of the unit. The dependent claims serve to further define the mechanical components of the elevation mechanism, such as the use of linear actuators, roller wheels, and tracks, while also specifying additional structural features like surface joints and grommet holes.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Elevation mechanism
(Claim 1)
An elevation mechanism is provided between said upper frame and lower frame. When the switch is actuated, the elevation mechanism adjusts the space between said upper frame and lower frame, changing the height of the main surface assembly. The elevation mechanism comprises two pairs of arms each having a roller wheel attached to a distal end relative to the main surface assembly.A motorized mechanical assembly located between the upper and lower frames that facilitates the vertical adjustment of the desktop height.
Main surface assembly
(Claim 1)
A motorized desktop stand unit comprising a main surface assembly designed to accommodate a monitor or laptop. The main surface has a left side, a right side, a front side, and a back side. A switch is provided in said main surface assembly to actuate the elevation mechanism.The primary upper work platform of the stand unit intended to support a monitor or laptop and housing the control switch.
Roller wheel
(Claim 1)
The elevation mechanism comprises two pairs arms each having a roller wheel attached to a distal end relative to the main surface assembly.A wheel attached to the distal end of the elevation arms to facilitate movement during height adjustment.
Scissor arms
(Claim 1)
