Benefits of technology

[0018]The present invention has the following advantages. When the press button is retracted to the ending position, the driven device and the stopping device are forced to release each other for the user to adjust the height between the inner and outer support portions. When the press button is returned to the starting position by the elastic force, the driven device and the stopping device are forced to latch with each other again. Therefore, the lower sleeve and the upper sleeve can be adjusted to provide a height of the seat armrest to fit the user's need. Furth

Abstract

A seat armrest includes a lower sleeve, an upper sleeve, a driving device, and an adjustable armrest piece. The lower sleeve includes a connecting portion, an inner support portion, and a cover. A stopping device is protruded from the shaft hole towards the axis of the shaft hole. The upper sleeve includes an outer support portion, an opening portion, two slide rails, a partition, and a driven device. The driving device includes a directing frame, a slide plate, a first contact end, and a second contact end. The armrest piece includes a lower slide cover, a slide cover and a press button, which has a release position and a lock position that enables the user to release or lock the driven device and the stopping device, in turn to adjust the height between the inner and outer support portions.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a seat armrest, in particular to the seat armrest composed of simplified components and capable of adjusting the using height and the front-and-back distance of the armrest.[0003]2. Description of the Related Art[0004]In general, a chair has a telescopic device installed separately on both sides of the chair to adjust the height of armrests, and users can operate the telescopic devices to adjust the height of placing both hands on the surface of the armrests respectively to enhance the comfort of sitting on the chair.[0005]A conventional seat armrest usually comprises a lower tube, an upper tube sheathed on the lower tube, a hand rail element fixed to the top of the upper tube and having a soft surface, a link rod mechanism with a complicated structure disposed between the upper and lower tubes, and a press button pivotally coupled to the link rod mechanism and exposed from the upper and...
