    • A child restraint seat is shown having a system for tightening the safety harness belt that includes an adjuster plate with the adjuster plate being slidably mounted on a guide track on the back side of the restraint seat. The adjuster plate includes a belt tensioning portion that contacts the safety harness belt at various positions between two opposite fixed ends of the safety harness belt. Movement of the adjuster plate along the guide track on the back side of the restraint seat causes the belt tensioning portion of the adjuster plate to change the slack length of the safety belt by an amount approximately equal to two times the distance which the adjuster plate is moved along the guide track. A pawl is part of the adjuster plate assembly and is biased into contact with teeth on the guide track to hold the adjuster plate in a predetermined position along the guide track.
    • 示出了儿童约束座椅具有用于紧固安全带束带的系统,该系统包括调节板,调节板可滑动地安装在约束座椅后侧的导轨上。 调节板包括带状张紧部分,其在安全带束带的两个相对的固定端之间的各个位置处接触安全带束带。 调节板沿着约束座背面的导轨的运动导致调节板的带张紧部分将安全带的松弛长度改变大约等于调节板的距离的两倍 沿导轨移动。 棘爪是调节板组件的一部分,并被偏置成与导轨上的齿接触,以将调节板保持在沿导轨的预定位置。

    • A dual purpose optical device that is convertible between binocular and stereoscope modes of operation while using a common eyepiece arrangement for both. The device includes a housing containing a pair of optic supports mounted side-by-side for lateral movement towards and away from one another. Each support preferably carries three lenses. Two lenses on each support serve as the eyepiece and are aligned in a common plane with an eyepiece opening through the housing and a rotatable mirror assembly. The assembly pivots substantially ninety degrees from opposing forty-five degree angle positions with respect to the plane through the eyepiece opening and the eye and field lenses so as to fold the lines of sight either up or down within the housing. A circular photo transparency reel is received horizontally in a slot provided on an upper side of the housing. Each optic support is provided with three fixed mirrors which fold the lines of sight directed downward by the rotating mirror through an objective lens located at an opposite end of the housing. The three lenses on each optic support collectively form a binocular lens train while two of the lenses of each set form a magnifying lens train. A spring biases the optic supports together and against tapered, longitudinally extending sides of a cam mounted for longitudinal movement in the housing. A wheel projects partially through the bottom of the housing and supports pinions that are engaged with racks on the cam to provide manual interpupillary spacing adjustment of the optic supports. In the stereosope mode of operation, the interpupillary distance between the eyepieces is automatically set in response to converting between the two modes so that it matches the distance separating corresponding stereo pairs.
    • 一种双用途光学装置,可在双目镜和立体镜操作模式之间转换,同时为两者使用公共目镜装置。 该装置包括壳体,其包含并排安装的一对光学支架,用于横向移动并且彼此远离。 每个支撑件优选地承载三个透镜。 每个支架上的两个透镜用作目镜,并且在公共平面中对准,其中目镜通过壳体开口和可旋转镜组件。 组件相对于通过目镜开口和眼睛和视场透镜的平面的相对的四十五度角位置枢转大致九十度,以便在壳体内上下折叠视线。 在设置在壳体的上侧的狭槽中水平地接收圆形照片透明卷轴。 每个光学支架设置有三个固定的反射镜,其通过位于壳体的相对端的物镜折叠由旋转镜向下指向的视线。 每个光学支架上的三个透镜共同形成双目透镜列,而每组的两个透镜形成放大透镜列。 弹簧将光学支撑件偏置在一起并且抵靠安装成在壳体中纵向移动的凸轮的锥形的纵向延伸的侧面。 轮部分地穿过壳体的底部并且支撑与凸轮上的齿条接合的小齿轮以提供光学支架的手动瞳孔间距调节。 在立体声操作模式中,响应于两种模式之间的转换,自动设置目镜之间的瞳孔距离,使得它与分离对应立体声对的距离相匹配。

    • An infant's swing is disclosed that has a frame, a swing arm, and a seat releasably mounted on the swing arm by a seat-to-frame coupler assembly that includes a pivot plate mounted to the back of the seat and a T-shaped connector mounted to the lower end of the swing arm. The connector is received in a mating cavity formed in the rear surface of the pivot plate, and the connector is engaged with the cavity by cooperation of slots in the cavity and posts on the connector. The pivot plate is pivotally mounted to the seat to permit the seat to pivot between a recline position and an upright position.
    • 公开了一种婴儿秋千,其具有框架,摆臂和通过座对框架联接器组件可释放地安装在摆臂上的座椅,该座椅对框架联接器组件包括安装到座椅后部的枢轴板和T形连接器 安装在摆臂的下端。 连接器被容纳在形成在枢转板的后表面中的配合腔中,并且连接器通过腔中的槽的配合与腔体接合并且在连接器上固定。 枢转板枢转地安装到座椅上,以允许座椅在倾斜位置和直立位置之间枢转。
