    • A failsafe stable cleat with automatic in-line line-locking includes a frame having proximate and a remote sides on substantially opposite sides of the frame and formed with a passageway, extending between the proximate and remote sides, for receiving a line and generally defining a cleat center line along which a line can move along a first line releasing direction from the proximate to the remote sides and a line pulling direction from the remote to the proximate sides; attaching members for attaching the frame to a support surface. A cam on the frame on one side of the passageway has a line engaging portion spaced a predetermined distance from the support surface, the cam being movable between a line releasing position and a line locking position. A pusher on the frame is positioned on an opposite side of the passageway in relation to the cam for selectively applying a force on the line in the direction of the cam A cam biasing member tends to urge the cam to disengage from the line while a pusher biasing member normally tends to move the line across the gap into contact with the cam while permitting the line to return to the passageway out of contact with the cam when sufficient tension is applied by the user off the cleat center line to create a force component to offset the pushing force created by the pusher biasing member. This promotes unlocking of the line and allowing the line to move in the first line releasing direction, engagement of the line by the cam to the line locking position creating a force couple which is a function of the predetermined distance, that tends to separate the frame from the support surface. A stabilizing element compensates for and offsets the force couple independently of the dimensions or configuration of the frame.
    • 具有自动线内线锁定的故障安全稳定防滑板包括框架,该框架在框架的基本相对的两侧具有邻近和远侧,并且形成有在近侧和远侧之间延伸的通道,用于接收线并且通常限定一个 一条线可以沿其沿第一线释放方向从近侧到远侧移动,以及从远程到最近侧的线拉动方向; 用于将框架附接到支撑表面的附接构件。 在通道一侧的框架上的凸轮具有与支撑表面间隔开预定距离的线接合部分,凸轮可在线释放位置和线锁定位置之间移动。 框架上的推动器相对于凸轮定位在通道的相对侧上,用于在凸轮的方向上选择性地在线上施加力。凸轮偏置构件倾向于推动凸轮与线分离,而推动器 偏压构件通常倾向于使线穿过间隙移动以与凸轮接触,同时当使用者从防滑钉中心线施加足够的张力以允许线返回至与凸轮接触的通道,以产生力分量 抵消由推动偏压构件产生的推力。 这促进了线的解锁并且允许线在第一线释放方向上移动,线通过凸轮与线锁定位置的接合产生了作为预定距离的函数的力耦合,其倾向于将框架 从支撑面。 稳定元件独立于框架的尺寸或构型补偿和抵消力联。

    • A deal with automatic line-locking includes a cam formed of a plurality of generally flat pressure-engaging segments or pressure pads that are angularly laterally offset to opposite sides of the cam plane an beyond the sheet(s) of flat material forming the cam, the segments or pads generally defining a line-receiving region having a generally uniform cross-section greater than the thickness of the sheet(s) of flat material configured to frictionally engage the line in the line locking position. Auxiliary sheave assemblies may be used to provide automatic failsafe operation by means of the cleat when raising or lowering an object on a hook or loop. A pusher may be used to automatically urge the line to move in the direction of the cam to lock the line especially when the line is released.
    • 自动线锁的处理包括由多个大致平坦的压力接合段或压力垫构成的凸轮,所述多个大致平坦的压力接合段或压力垫成角度地横向偏移到凸轮平面的相对侧,超过形成凸轮的平坦材料的片材, 所述段或垫通常限定线接收区域,其具有大于平坦材料的片材的厚度的大致均匀的横截面,所述平板材料的片材被配置为摩擦地接合线路锁定位置中的线。 辅助滑轮组件可以用于在提升或降低钩或环上的物体时通过防滑板提供自动故障保护操作。 可以使用推动器来自动地将线沿着凸轮的方向移动以锁定线,特别是当线被释放时。
