    • An in-wall mounted housing or enclosure for an electronic apparatus, such as used as part of a wireless sound system, is configured with a relatively large volume chamber which requires a limited size cut-out for installation. With such a configuration, the enclosure can be mounted within a wall, ceiling, or floor structure while having a sufficient volume to contain all of the required electrical components for a particular application, such as in a wireless sound system. In one arrangement, the housing is configured with two or more chambers where each chamber contains a distinct electrical component. Separation of certain electrical components into distinct chambers can minimize electrical interference between the components during operation. In one arrangement, the housing is further configured to carry both low voltage and high voltage components within the separate chambers while minimizing electrical interference among the components.
    • 用作电子装置的壁挂安装的外壳或外壳,例如用作无线音响系统的一部分,其配置有相对较大的容积室,其需要有限尺寸的切割以进行安装。 通过这样的配置,外壳可以安装在墙壁,天花板或地板结构中,同时具有足够的容积以容纳特定应用(例如无线音响系统)中的所有所需的电气部件。 在一种布置中,壳体配置有两个或更多个腔室,其中每个腔室包含不同的电气部件。 将某些电气部件分离成不同的腔室可以使操作期间部件之间的电气干扰最小化。 在一种布置中,壳体还被配置为在分离的腔室内承载低电压和高电压部件,同时最小化部件之间的电干扰。

    • An overload warning system for a winch hoist of the type that includes a drum that rotates about a drum shaft, a handle that is received in a socket, wherein the handle can be used to turn the drum, and a movable frame that is located between the socket and the housing. The socket is coupled to the drum shaft. There is a shear pin with one end embedded in the frame and the other end embedded in the socket, the shear pin defining a relatively weak shear zone located between the frame and the socket. There is an elongated opening defined in the socket and a projection projecting from the frame and into or through the elongated opening. If the shear pin fails under rotational load applied through the handle, the socket will rotate relative to the frame until the edge of the elongated opening contacts the projection. The socket movement provides tactile feedback that the shear pin has failed, while maintaining control over the hoist operation via the handle.
    • 一种用于绞盘式起重机的过载报警系统,其包括围绕鼓轴旋转的滚筒,容纳在插座中的手柄,其中手柄可用于转动滚筒,以及可移动框架,其位于 插座和外壳。 插座连接到鼓轴。 存在一个剪切销,其一端嵌入框架中,另一端嵌入插座中,剪切销限定位于框架和插座之间的相对较弱的剪切区域。 在插座中限定有一个细长的开口,以及从该框架伸出并穿过细长的开口的突起。 如果剪切销在通过手柄施加的旋转载荷下失效,则插座将相对于框架旋转,直到细长开口的边缘接触突起。 插座运动提供了剪切销失效的触觉反馈,同时通过手柄控制起重机操作。
