摘要： A platform ladder apparatus (2) has a transport position and a use position in which the apparatus is arranged to lean against a wall (W) for performing work at an elevated level. The apparatus (2) has a ladder (4) and a working platform (20). A proximal side of the platform is pivotally connected at an upper end of the ladder such that it may be pivoted towards the ladder (4) to a stowed position essentially parallel to the ladder (4). The apparatus further comprises a pair of wall support arms (80) for stabilizing the apparatus in the use position in relation to the wall. The wall support arms (80) are connected to the platform (20) for movement between a stowed arm position in which the arms (80) project out from a distal side (24) of the platform (20) thereby preventing use of the apparatus, and a stabilizing arm position in which the arms (80) project sideways from the platform (20) in opposite lateral directions, respectively, for stabilizing the apparatus (2) in relation to the wall (W).

摘要： A mechanical extension ladder support stand that a worker can mount on an extension ladder. Perform work or repairs on interior walls or stairways safely. The device is installed and removed from the ladder, disassembled or repaired without need of tools, safely. The ladder stand is expandable to fit extension ladders of different widths and lengths, without use of tools. When set up to work on a wall, the ladder stand's support board will automatically pivots to match the angle at top of ladder to the wall's surface, without any tools or adjustment. The ladder stand will always rest a padded support board, safety on two or more of the walls vertically framing members. Without damaging or marring the walls. The ladder stand operates safely for the layman on the interior walls without need of any tools, only human hands.

摘要： A self-leveling boat bumper system attached to a nautical structure can include a floating bumper arrangement having a float element, a float extension, and a boat bumper; and a receiver, fixed to the nautical structure and moveably engaged with the arrangement, or fixed to the arrangement and moveably engaged with a guide fixed to the nautical structure. When floating within a body of water, the float element can provide a buoyancy force that maintains the boat bumper in a static position between, and including, first and second positions, and as the level of the water changes.

摘要： A climbing support is provided for aiding a climber in scaling a tree, pole, or other generally vertical surface. The climbing support includes an elongate body that supports a plurality of steps, a strap, cable, or other flexible securing member that is wrapped around the tree, and a retractor for stowing the flexible securing member so that it is extendable and retractable from the support. The climbing support is thus substantially self-contained so that it does not require separate components for installation or use. Standoffs may be provided for stabilizing the support in a location spaced from the tree. Optionally, the climbing support's steps, standoffs, and elongate body are collapsible to compact configurations for stowage or transport.
摘要翻译： 提供攀爬支撑，用于帮助登山者缩放树，杆或其他大致垂直的表面。 攀爬支撑件包括支撑多个台阶的细长主体，缠绕在树上的条带，缆线或其它柔性固定构件，以及用于收起柔性固定构件的牵开器，使得其能够从支撑件伸出并缩回 。 因此，攀爬支撑件基本上是独立的，因此它不需要用于安装或使用的单独部件。 可以提供支座以在与树隔开的位置稳定支撑。 可选地，爬升支撑件的台阶，支座和细长主体可折叠以用于装载或运输的紧凑配置。

摘要： A ladder rest and restraining device is provided for the edge of a roof or other elevated structure which is regularly or periodically accessed by means of an extension ladder or other similar device. The device may be permanently or removably mounted on the edge of the roof or structure where the ladder is normally positioned, to limit movement of the ladder horizontally, sideways, as well as vertically downward. The device includes an elongated primary support, a pair of legs extending from spaced apart locations of the primary support, the legs terminating in mounting feet. A plurality of restraining members extend from additional spaced apart locations of the primary support. The mounting feet are adapted to engage any of horizontal, vertical or angled surfaces associated with the elevated structure, such that a first sub-plurality of the restraining members are adapted to abut an underside of a selected rung to prevent downward movement of the ladder. A further sub-plurality of the restraining members are outwardly spaced from the first sub-plurality and adapted to limiting lateral displacement of the stanchion members in each of opposite directions.
摘要翻译： 梯子和限制装置被设置用于通过延伸梯或其它类似装置有规律地或周期性地接近的屋顶或其他提升结构的边缘。 该装置可以永久地或可拆卸地安装在梯子通常定位的屋顶或结构的边缘上，以限制梯子的水平，侧向以及垂直向下的运动。 该装置包括细长的主要支撑件，一对腿部，其从主支撑件的间隔开的位置延伸，腿部终止于安装支脚。 多个限制构件从主支撑件的附加间隔开的位置延伸。 安装脚适于接合与升高的结构相关联的任何水平的，垂直的或成角度的表面，使得约束构件的第一子组件适于邻接所选梯级的下侧，以防止梯子向下移动。 另外的多个所述约束构件与所述第一子组件向外间隔开并且适于限制所述支柱构件在每个相反方向上的横向位移。
