    • The specification discloses a wall panel base construction including a foot, a wall panel supporting assembly, and a plurality of oppositely threaded members extending between the foot and the supporting assembly. The lower portion of each threaded member is secured within a block, which is in turn pivotally supported on the foot to prevent the threaded members from jamming during height adjustment. The blocks are also laterally shiftable with respect to the foot to further accommodate movement of the threaded member during height adjustment. In a second aspect, the upper end of the threaded member includes a chuck for receiving a rotatable driving tool; and the panel supporting assembly defines an aperture axially aligned with the threaded member, whereby the chuck can be freely accessed to facilitate rotation of the member.
    • 该说明书公开了一种墙板基座结构,其包括脚,墙板支撑组件和在脚和支撑组件之间延伸的多个相对螺纹的构件。 每个螺纹构件的下部固定在块内,该块又可枢转地支撑在脚上,以防止螺纹构件在高度调节期间卡住。 这些块也可以相对于脚横向移位,以进一步适应螺纹构件在高度调节期间的运动。 在第二方面,螺纹构件的上端包括用于容纳可旋转的驱动工具的卡盘; 并且面板支撑组件限定与螺纹构件轴向对齐的孔,由此卡盘可以自由地接近以便于构件的旋转。
