RESTRICTION REMOVAL OPERATION MECHANISM FOR RAISING/FALLING MOTION OF RISING LEG IN TABLE APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent an associated motion between both release operation mechanisms for a reduction in control force and elimination of disadvantage such as catching articles and hand therein.;SOLUTION: Both end sides of a table board 4 are disposed with release operation means 7 for removing the restriction of an auxiliary raising/falling means 5, respectively. One of the release operation means 7 is coaxially fixed with a restriction removal operation member 19, the restriction removal operation member is positioned at a square hole. A displaced shaft of the release operation means 7 is fixed with a linear member so as to be protruded from a fixing position to the upper from the square hole. The end of the restriction removal operation member 19 is made to abut on the back side of the square hole 7a of the release operation means 7 to be positioned close to the top of an operation shaft 18 of the auxiliary raising/falling means 5. The other release operation means 7 on the side where the restriction removal operation member 19 is not disposed and the restriction removal operation member 19 are connected by the linear member stretched through guide pulleys 20 and 20 turnably held on spindles 12 of base portions 6 for fixing rising legs.;COPYRIGHT: (C)2004,JPO
