机の天板の高さ調節装置

Height adjusting device for desk top plate

Abstract

PROBLEM TO BE SOLVED: To provide a highly safe height adjusting device for the top plate of a desk in which the whole desk is never inclined backward according to the raising operation of the top plate to fall a matter placed on a top plate, or the desk itself is never overturn backward even if a load larger than the extending force of a gas spring is added to the top plate. SOLUTION: To raise a top plate 1 when the load added to the top plate 1 exceeds the extending force of a gas spring, the front part of an operation beam 7 arranged under the front part of the top plate 1 is pressed down, whereby the rear part of the top plate 1 can be supported by the rear part of the operation beams 7, and the top plate 1 can be easily pressed up with a small force. Therefore, even if a load is locally added to the rear part of the top plate 1, particularly, the top plate 1 can be raised and lowered with good balance without inclining the table 1 backward more than the front part of the top plate 1.

(57)【要約】 【課題】 天板に、ガススプリングの伸張力よりも大き い荷重が加わっても、天板の上昇操作に伴って、机全体 が後方に傾斜して天板上の載置物が落下したり、机自体 が後方に転倒することのない、安全性の高い机の天板の 高さ調節装置を提供すること。 【解決手段】 天板1にかかる荷重が、ガススプリング の伸張力より上回った場合に天板1を上昇させるために は、天板1の前部の下方に配設された操作杆7の前部を 下方に押し下げれば、操作杆7の後部により天板1の後 部を支持出来るとともに、小さい力で容易に上方に押上 げることが出来るため、特に天板1の後部に荷重が偏っ て加わっても、天板1の前方より、天板1を後方に傾け ることなくバランス良く昇降させることが出来る。
