摘要： A mechanical arm mechanism for moving a table or similar board type work surface in an arcuate path from a stored position to one or more user positions at various selected elevations and angles of inclination. The mechanism uses at least one set of spaced apart arms each of which has one end pivotally attached to a respective fixed pivot point on a support member and the opposite end pivotally attached to a respective movable pivot point on the bottom or back side of a board member with the lengths between the fixed pivot points, the moveable pivot points and the arms forming the sides of a trapezoid which sides change their relative angular orientation as the table or board is moved in its arcuate path of travel.

摘要： A mechanical arm mechanism for moving a user surface such as an electronic monitor for a computer or television and a related keyboard or control board in an arcuate path from a stored position to one or more user positions at various selected elevations and angles of inclination. The mechanism uses at least one set of spaced apart swingable arms each of which has one end pivotally attached to a respective fixed pivot point on a support member and the opposite end pivotally attached to a respective movable pivot point on the bottom or back side of the electronic monitor with the lengths between the fixed pivot points, the moveable pivot points and the arms forming the sides of a quadrilateral which sides change their relative angular orientation as the table or board is moved in its arcuate path of travel. A similar group of swingable arms also forming a quadrilateral are pivotally connected at one end to fixed pivots on the support member and the opposite ends are pivotally attached to the keyboard or control board member to enable such member to move arcuately with the Monitor from the stored to a user position.
摘要翻译：一种机械臂机构，用于将诸如用于计算机或电视的电子监视器的用户表面以及相关的键盘或控制板以弧形路径从存储位置移动到以各种选定的高度和倾斜角度的一个或多个用户位置。该机构使用至少一组间隔开的可摆动臂，每个摆动臂的一端可枢转地附接到支撑构件上的相应固定枢转点，并且相对端枢转地附接到位于支撑构件的底部或背面上的相应可移动枢转点电子监视器，其具有在固定枢转点之间的长度，可移动枢转点和形成四边形侧面的臂，当侧板或板在其弓形行进路径中移动时，该侧面改变其相对角度定向。也形成四边形的类似组的可摆动臂在一端枢转地连接到支撑构件上的固定枢轴上，并且相对端枢转地附接到键盘或控制板构件，以使得该构件能够与监视器一起弧形地从存储的到用户位置。
