Foldable support for lifting table or chair

Abstract

The invention discloses a foldable support for a lifting table or chair. The foldable support comprises a lifting mechanism, a pair of transverse beams arranged symmetrically and a driving mechanism for driving the lifting mechanism to lift. The lifting mechanism comprises a pair of lifting columns arranged correspondingly. The lifting columns are hinged with the ends of the transverse beams through a first connecting device, and are folded around the first connecting device. The transverse beams are hinged through a second connecting device, and are folded around the second connecting device. The invention further discloses a lifting table or chair with the foldable support. The lifting table or chair comprises a panel and a support arranged under the panel. The columns and the transverse beams can be folded, so that occupied space is reduced during transportation, package size is small, and storage and transportation are easy; when a user assembles the lifting table, only need to follow the instructions, and assembling effect can be guaranteed.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a foldable lift table or stool and a foldable support for the lift table or stool.

AI Technical Summary

Problems solved by technology

In the entire assembly process, the installation requirements of beams and columns are the highest, and this part of the structure occupies the most space for packaging and transportation.

However, the beam and the pole are directly fixed together and cannot be folded, and the beam cannot be folded, which is inconvenient for packaging and transportation.

[0006] (2) Although the above-mentioned electric lifting table solves the problem of being able to lift, but when the column load is running under any load within the overload, when the desktop it is connected to hits the window sill, writing cabinet, playing child, etc., It is impossible to respond quickly, and it must be responded when the load reaches the specified value. At this time, the table may have been damaged, and the child has encountered a safety accident. The safety of the product is not enough, so add a It is very necessary for the system to respond as long as the load of the table connected to it changes when the column is under any load operating state.
