Sofa table with adjustable height

Abstract

A sofa table is height adjustable comprises horizontal table top with all or a portion that can be raised in an upward direction laterally using a height adjustable telescopic means. This capability will expand the use of the sofa table to serve the functions of an ordinary table that can be used for activities like writing or eating. The undercarriage includes an inclined adjustable telescopic means pivoted to the table top and the bottom of the leg frame assembly to enable sliding upwards and downwards movements. A controlling fixture is integrated into the adjustable telescopic means to lock the table top at the desired height level within its range of adjustment. A releasable angled lever is utilized to engage and disengage the locking mechanism is connected to the telescopic means. A press on the lever will disengage the locking mechanism and while holding down the lever and with a lifting force applied simultaneously on the table top will allow the table top to elevate to the desired height within its range of adjustment.

Description

[0001] The present invention relates generally to a sofa table and more particularly to a sofa table having a top, part or all of which is adjustable as to height. In particular, this invention allows a sofa table to be used as dining table or writing table while sitting on an ordinary sofa.BACKGROUND OF INVENTION[0002] The limited space available in many town houses as well as apartment imposes to take the greatest advantage of the available space.

AI Technical Summary

Benefits of technology

[0004] It is therefore an object of the present invention to provide an adjustable means to a sofa table that enables users to elevate the height of a portion of the sofa table and transform the sofa table into a table with higher top.

[0005] It is an object of the present invention to provide an adjustable mechanism to enable a portion of the sofa table to be raised to the desired height. It is a further object of the present invention to provide the necessary mechanism to engage and disengage the locking mechanism so that the sofa table can conveniently and shiftily be adjusted to a desired height. It is also paramount important to ensure that the elevated sofa table is well supported and balanced in weight due to the variation in the gravity level for different portions of the table, in order to avoid the table being toppled.

[0010] In order to provide further stability as well as enhance the smooth upward and downward movements for the adjustable section of the table top, the elongated supporting member of the adjustable section of the table top is engaged in a receiving slot. The incorporation of roller and railing system could be included to further assist smoother sliding movements. Extra members incorporated unto the stationary portion of the table are also intended to counterbalance those extra moment of force created by the extended table top portion to avoid the said table from being toppled.

Problems solved by technology

However, the latter design is not so favorable as motor as well as the battery have to be periodically serviced, therefore this indirectly will add extra burden to the cost.
