摘要： The current invention is directed to a clamping assembly for clamping a ladder to a support such a roof gutter wall or scaffolding tubing. The clamping assembly includes a pair of opposing arms hinged together and spring biased to assist in locating the clamping arms about the support. The inner side of the clamping arm has a recess to accommodate the support or part thereof. The clamping assembly has a fastener to fix the clamping arms in position and a securing means such as a fixed chain to position about the stile or rung of a ladder. The clamping assembly provides the advantage that a section of the clamping arms clamps to a section of the support thereby providing a clamping force over a sectional area rather than at a single point.
摘要翻译：本发明涉及一种用于将梯子夹紧到诸如屋顶沟槽壁或脚手架管的支撑件的夹紧组件。夹紧组件包括一对铰链的相对的臂，弹簧被偏置以帮助夹持臂围绕支撑件定位。夹持臂的内侧具有用于容纳支撑件或其一部分的凹部。夹紧组件具有将夹持臂固定就位的紧固件和诸如固定链条的固定装置，以围绕梯子的台阶或梯级定位。夹紧组件提供的优点是夹紧臂的一部分夹持在支撑件的一部分上，从而在截面积而不是在单个点处提供夹紧力。

摘要： A ladder safety device (100) is usable for holding and stabilizing a ladder in a safe and stable manner while being used, by way of securing a ladder relative to continuous horizontal guttering at the edge of a building. The device (100) locks to the gutter by way of locking jaws (130), (160) and is secured to the side rail of a ladder by way of an adjustable locking bar (140). Improvements to the initial design include an adjustable jaw (134) for clamping different thicknesses of gutter or other support material, selectable jaw strips (164a) to accommodate different types of gutters, and a ratcheting height adjustment carriage (150) for the locking bar (140) to accommodate different sizes of ladder rails.
