## Abstract

A lifting system for use with furniture elements for improving ergonomics includes an electric linear actuator, a casing member, a pedestal structure, and a pair of rails. The pedestal structure is configured to travel telescopically inside the casing member via the pair of rails. A furniture element is positioned on the top the casing member. The furniture element, such as a table or desk, is configured to raise and lower via the electric linear actuator. The improved lifting system provides a cost effective solution to raise and lower the table or desk.

## Claims

### Claim 1

A lifting system comprising:
an electric linear actuator;
a casing member having an outer top surface, an inner top surface, a pair of inner side surfaces, and an open bottom;
a pair of rails fastened to the pair of inner side surfaces;
a pedestal structure having a pair of exterior sides, wherein an equal number of grooved blocks are fastened to each exterior side, wherein the grooved blocks are configured to engage and travel the pair of rails such that the pedestal structure is configured to travel telescopically inside the casing member, wherein the pedestal structure includes a framework assembly providing structural support to the pedestal structure and the lifting system, and wherein the framework assembly includes a pair of horizontal frame members positioned between the pair of exterior sides, and at least one vertical rib positioned centrally between the pair of horizontal frame members; and,
a furniture element positioned to the outer top surface of the casing member, the furniture element configured to raise and lower via the electric linear actuator.

### Claim 2 (depends on 1)

The lifting system of claim 1, wherein the furniture element is a table or desk.

### Claim 3 (depends on 1)

The lifting system of claim 1, wherein the framework assembly includes reinforcement blocks positioned in four interior corners where the pair of exterior sides and the pair of horizontal frame members join.

### Claim 4 (depends on 1)

The lifting system of claim 1, wherein the electric linear actuator comprises a piston member, top clevis member, and a bottom clevis member, wherein the top clevis member is connected to a top bracket section of the casing member and the bottom clevis member is connected to an upper horizontal frame member of the pair of horizontal frame members.
