    • A keyboard storage device assembly of parallelogram shape is disclosed comprising first and second arms (18, 20), and first and second parallel platform housing arms (12, 14), each having an inner channel (42) axially receiving the arms (18, 20) therein with the arms (18, 20) moving reciprocally within the channels (42) between a retracted storage position and an extended position. A back plate (16) connects rearward ends of the arms (12, 14) and a wrist rest (26) connects forward ends of the arms (18, 20) such that the assembly may be varied in width and length. A pair of keyboard supporting plate arms (22, 24) have forward ends pivotally coupled to forward ends of the arms (18, 20) and pivot between a horizontal orientation over the arms (18, 20) into a vertical or inclined position. A keyboard positioned upon the arms (22, 24) is thus pivoted therewith and maintains an orientation such that the keys of the keyboard face forwardly and remain accessible to the user throughout the range of motion.
    • 公开了一种平行四边形形状的键盘存储装置组件,其包括第一和第二臂(18,20)以及第一和第二平行平台壳体臂(12,14),每个臂具有轴向地接收臂(18)的内部通道(42) 其中臂(18,20)在通道(42)之间在缩回的存储位置和延伸位置之间往复运动。 背板(16)连接臂(12,14)的后端并且腕托(26)连接臂(18,20)的前端,使得组件可以在宽度和长度上变化。 一对键盘支撑板臂(22,24)具有枢转地联接到臂(18,20)的前端的前端,并且在臂(18,20)之间的水平取向之间枢转成垂直或倾斜的位置。 定位在臂(22,24)上的键盘因而与其枢转并保持定向,使得键盘的键向前并且在整个运动范围内保持对用户的访问。
