    • A support base for a display monitor provides for the stable orientation of the monitor over a range of tilt angles. An upper portion of the base includes a concave surface adapted to receive a complementary convex lower portion of the display monitor's cabinet. The concave surface of the base includes a pair of spaced, upraised, parallel, elongated, lateral guide rails adapted to receive and engage respective guide rail assemblies positioned on the convex lower portion of the monitor. The convex lower portion of the cabinet is further provided with a center projection for insertion within an elongated center aperture in the concave support surface positioned between the paired guide rails. The center projection is coupled to the base by means of a stretchable element such as an extension spring for applying a moment to the monitor tending to rotate it in a first direction within the concave surface. The biasing spring is coupled to the monitor such that the first direction of rotation is opposite to the rotational moment of the monitor due to its center of gravity. The monitor is thus maintained, once oriented as desired, at a stable tilt angle by these opposing moments. Each of the guide assemblies positioned on the cabinet's lower convex surface includes engaging means such as the combination of a spring washer and tension clip for engaging a respective guide rail in maintaining the monitor firmly positioned within the base's concave surface.
    • 显示监视器的支撑底座提供监视器在一定范围的倾斜角度上的稳定方向。 底座的上部包括适于容纳显示监视器机柜的互补的凸下部的凹面。 底座的凹面包括一对间隔的,提升的,平行的细长的横向导轨,其适于容纳和接合位于监视器的凸下部上的相应的导轨组件。 机柜的凸下部还设置有中心突起,用于插入位于成对的导轨之间的凹形支撑表面中的细长的中心孔内。 中心突起通过诸如延伸弹簧的可拉伸元件联接到基座,用于向显示器施加力矩,倾向于使其在凹面内沿第一方向旋转。 偏置弹簧联接到监视器,使得第一旋转方向由于其重心而与监视器的旋转力矩相反。 因此,通过这些相反的时刻,监视器一旦按需要定向成稳定的倾斜角度。 位于机柜下凸表面上的每个导向组件都包括接合装置,例如弹簧垫圈和张紧夹的组合,用于接合相应的导轨,以使监视器牢固地定位在基座的凹面内。

    • An ultra-compact projection television receiver is disclosed comprising in combination cabinet means for enclosing the receiver components including a vertically reciprocable, rear projection viewing screen selectively storable in the cabinet. Precision elevating means provides for raising and lowering the screen between a stored position in the cabinet and a receiver-operable viewing wherein the screen is emerged. A television system has an ON control mode for providing television sound and pictures and an OFF control mode. Control means coupled to the elevating means and the television system provide for sensing the position of the screen in its reciprocation, and obstructions to said reciprocation manifested by increased resistance to said reciprocation, and correlatively controlling the elevating means and the OFF/ON control modes of the television system in response thereto. The control means are programmed to cause the screen to rise smoothly to its raised position without an abrupt stop and pictures to appear and sound to be heard the instant the raised position is attained. Safety is enhanced as obstructions to screen reciprocation are sensed and the reciprocation is stopped. The receiver is caused to automatically place the television system in the OFF mode when the screen is stored.
    • 公开了一种超紧凑型投影电视接收机,其包括用于封闭接收器组件的组合柜装置,包括可选择性地存储在机柜中的可垂直往复运动的后投影观察屏幕。 精密提升装置用于在橱柜的存储位置和出现屏幕的接收器可操作的观看之间提升和降低屏幕。 电视系统具有用于提供电视声音和图像的ON控制模式以及OFF控制模式。 耦合到提升装置和电视系统的控制装置提供用于感测屏幕在其往复运动中的位置,以及阻碍所述往复运动的障碍,这表现为对所述往复运动的增加的阻力表现,并且相关地控制升降装置和OFF / ON控制模式 电视系统响应于此。 控制装置被编程为使得屏幕平滑地升高到其升高位置,而不会突然停止,并且在达到升高位置的瞬间出现图像并听到声音。 当检测到屏障往复运动的障碍物并且停止往复运动时,安全性得到增强。 当存储屏幕时,使接收机自动将电视机置于OFF模式。
