AI Technical Summary

Benefits of technology

The telescopic module achieves reduced friction and wear, ensuring stable and smooth movement of the worksurface, maintaining performance over time by using rollers to reduce contact stress and incorporating adjustable pressure mechanisms.

Problems solved by technology

However, heights of people are different, so that the desk and chair with a consistent height can't meet all heights of the users.
It may wear the ring, and make it lose the function of reducing the friction.
The worn ring causes an unstable telescoping motion of the telescopic stand as well.
However, the inner tube and the outer tube still will be worn after a long time of operation.

Embodiment Construction

[0024]FIG. 1 and FIG. 2 show a telescopic module of the first preferred embodiment of the present invention, which is connected to a worksurface 10 to adjust a height of the worksurface 10. The telescopic module may be incorporated into a desk, a chair, or any other devices which is able to elevate and lower the worksurface 10. It is noted that usually there are a plurality of the telescopic modules are incorporated.

[0025]The telescopic module of the first preferred embodiment of the present invention includes a first tube 20 and a second tube 30. The first tube 20 has a passageway 22, in which the second tube 30 is received for free reciprocation. A plurality of rollers 40 are pivoted on the first tube 20 and touch the second tube 30.

[0026]The first and the second tubes 20, 30 are rectangular tubes. Four of the rollers 40 are pivoted on four sides of the first tube 20 to touch four outer sides 32 of the second tube 30.

[0027]The second tube 30 is moved relative to the first tube 20 ...

Abstract

A telescopic module, which may be incorporated in a desk or a chair to elevate or lower a worksurface, includes a first tube, second tube, and a plurality of rollers. The first tube has a passageway, in which the second tube is received for reciprocation. The rollers are pivoted on the second tube or the first tube, or both to touch an inner side of the first tube and an outer side of the second tube to be turned when the second tube is moving. The rollers may reduce the friction between the first and the second tubes when the second tube is moving.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a divisional application of U.S. application Ser. No. 15 / 664,598, filed on Jul. 31, 2017, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION1. Technical Field[0002]The present invention relates to a desk or a chair, and more particularly to a telescopic module of a desk or a chair for elevating and lowering a worksurface.2. Description of Related Art[0003]Typically, a conventional desk has a consistent height of a worksurface, and a user may sit on a chair to read, write, or operate a computer on the desk. However, heights of people are different, so that the desk and chair with a consistent height can't meet all heights of the users.[0004]An improved desk has a telescopic stand to adjust its height. The conventional telescopic stand has an inner tube and an outer tube to elevate or lower the worksurface by moving the inner tube, and fix the inner tube to the outer tub...
