    • A power operated tape measure enables extension of a tape via a drive mechanism, as well as retraction of the tape through a mechanical decoupling within the drive mechanism. The tape measure has a housing within which is positioned a spring-biased tape assembly, the drive mechanism and a clutch. The spring-biased tape assembly includes an annular reel onto which is wound a tape having indicia for taking length measurements. The drive mechanism includes a driving gear and a driven gear, and is adapted to engage with a bottom surface of the tape to extend the tape out of the housing. The clutch is adapted to displace the driven gear out of engagement with the driving gear and thereby decouple the driving and braking force provided by the drive mechanism from acting upon the bottom surface of the tape to permit the spring-biasing of the tape assembly to retract the tape into the housing.
    • 电动卷带测量可以通过驱动机构延伸带子,以及通过驱动机构内的机械去耦退回带子。 卷尺具有壳体,在该壳体内定位有弹簧偏置的带组件,驱动机构和离合器。 弹簧偏压的带组件包括环形卷轴,在其上缠绕具有用于进行长度测量的标记的带。 驱动机构包括驱动齿轮和从动齿轮,并且适于与带的底表面接合以将带延伸出壳体。 离合器适于使从动齿轮与驱动齿轮脱离接合,从而使由驱动机构提供的驱动力和制动力解除作用在带的底表面上,以允许带组件的弹簧偏压缩回 磁带进入外壳。

    • A folding headboard collapsible crib is provided including front and rear walls and collapsible left and right end walls. Safety hinge mechanisms are provided at the left and right end wall portions of the crib and a stop block system on the mattress support to eliminate pinch points and snag points at the foldable headboard and/or footboard locations. A mattress support platform is hingedly connected to a rear wall of the crib and is supported substantially around its entire periphery for enhanced maximum load bearing capacity. A strangulation proof strap system is carried on the mattress support platform for holding the crib in a collapsed configuration when not in use.
    • 提供折叠床头板折叠床,包括前壁和后壁以及可折叠的左右端壁。 安全铰链机构设置在婴儿床的左右端壁部分和床垫支撑件上的止动块系统,以消除可折叠床头板和/或脚踏板位置处的夹点和阻塞点。 床垫支撑平台铰接地连接到婴儿床的后壁,并且基本上围绕其整个周边支撑,以提高最大承载能力。 在不使用的情况下,床垫支撑平台上承载有扼杀证明带系统,用于将婴儿床保持在折叠构型中。
