Seat with tray

Abstract

The invention relates to a seat with a tray. The seat with the tray comprises a seat body and a tray assembly, armrests are arranged on the two sides of the seat body, the tray assembly is formed by connecting a keyboard support and supporting frames, the keyboard support is connected with the positions, lower than the upper edges of the armrests, of the front ends of the armrests on the two sides, the two ends of the keyboard support are flatly arranged on the supporting frames on the two sides respectively, and the supporting frames are connected with the armrests. The seat with the tray has the advantages that due to the fact that the keyboard support are movably connected with the positions, lower than the upper edges of the armrests, of the front ends of the armrests on the two sides through rotating shafts, a user can arrange the keyboard support conveniently according to needs; due to the fact that the supporting frames are hinged to the armrests, the supporting frames can rotate around the armrests so that the user can adjust the best angle freely according to needs. The seat with the tray controls all the turnup ligaments of the hands to be in a loose state, the anti-fatigue ability of the user is enhanced, the structure is simple, the seat is economic and practical, and people can use a computer more comfortably.

Description

technical field [0001] The invention relates to a seat with a tray. technical background [0002] At present, when working or studying, sometimes you need to use the computer, and of course you cannot do without the keyboard and mouse. After a long time, the ligaments in the back of the hand and wrist will feel tired and sore, which is what people often call muscle pain. Moreover, since the key surface is generally higher than the armrest of the chair, and the fingertips are higher than the palm and wrist, there is an upward angle between the back of the hand and the forearm. To maintain this angle, the ligaments that control the lifting of the hand must be continuously tightened and raised. This not only causes ligament fatigue, but also because the ligaments that control the index finger, middle finger and ring finger are all gathered in the center of the wrist on the back of the hand, and the three ligaments are close together. , so that the surfaces of the three adjacen...

Moreover, since the key surface is generally higher than the armrest of the chair, and the fingertips are higher than the palm and wrist, there is an upward angle between the back of the hand and the forearm. To maintain this angle, the ligaments that control the lifting of the hand must be continuously tightened and raised. This not only causes ligament fatigue, but also because the ligaments that control the index finger, middle finger and ring finger are all gathered in the center of the wrist on the back of the hand, and the three ligaments are close together. , so that the surfaces of the three adjacent ligaments rub against each other, especially the ligaments controlling the index finger and middle finger wear each other the most
