Ultra-thin lifting table

Abstract

An ultra-thin lifting table includes a lower platform, an upper platform, a movable brace, and a gas-assisted extension strut. The upper platform is located above the lower platform and configured to move up and down with respect to the lower platform. The movable brace includes an inner frame and an outer frame that are crossed and pivotally connected. The inner and outer frames are nested together and installed between the upper and lower platforms. Pivot of the inner and outer frames drives the upper platform to move up and down with respect to the lower platform. The gas-assisted extension strut provides gas-assisted thrust and is pivotally connected between the inner and outer frames for generating a lifting force when the inner and outer frames have an angle of cross therebetween. Thereby, when folded down, the inner and outer frames are horizontally placed between the upper and lower platforms.

Description

BACKGROUND OF THE INVENTION1. Technical Field[0001]The present invention relates to desktop lifting devices, and more particularly to an ultra-thin lifting table that has crossed and pivotally connected frames so as to have a reduced height when folded down.2. Description of Related Art[0002]In this modern world, people's daily life is highly interlaced with computers, networks, and communications. This makes us spend most time of a day in front of computers to handle things, browse news, learn knowledge, or communicate remotely, for either work or personal life. Therefore, the risk of healthy issues due to long-time sitting or poor sitting postures is threatening people increasingly.[0003]There are many lifting platforms / lifting tables on the market that are used to change height of things placed thereon and to prevent the foregoing healthy risks by allowing user to conveniently change postures between sitting and standing.

AI Technical Summary

Benefits of technology

The present invention is an ultra-thin lifting table that can be placed on an existing office desk. The table has a nested movable brace that can save space when folded down. It is light and compact, easy to move and set up, and comfortable to use when folded. The table uses reverse-U-shaped frames and a scissor-type lifting mechanism providing a balanced supporting force for smooth lifting. It also uses accommodating spaces on the upper and lower platforms to further reduce its thickness and make it more comfortable to use. The table is ideal for high versatineness and maneuverability in modern working demands.

Problems solved by technology

Therefore, the risk of healthy issues due to long-time sitting or poor sitting postures is threatening people increasingly.

However, the standing post is not foldable and thus less space-efficient, and the entire device's installation and displacement are relatively inconvenient.

Nevertheless, when moving upward, the platform can incline forward or backward in its pivotal route (opposite to vertically moving upward and downward), making it less suitable to occasions where special restriction is a concern.

Although the scissor-type lifting platforms allow vertical lifting, they still have some structural defects.

Besides, a lifting platform is relatively bulky due to its electric mechanism, and thus is usually fixedly installed, making it less maneuverable.

Even if the device is folded down (at its lowest position), it has a significant thickness, forming a considerable height difference with the desk top, so the use is less comfortable.

If such a configuration is applied to a lifting table, it can be structurally simplified and lightweighted due to the reduced load demand, but this also means its overall supporting strength is decreased.

Where the load puts its most weight on the slidable side, the device tends to become instable or even turn over.

This is a problem of the known scissor lifting devices with single side slide needs to overcome.

Besides, when used as a desk-top lifting device, the known structure still has a considerable thickness, making it fail to meet users' needs.
