摘要： Prior ladder levelling devices are difficult to adjust to a surface because it is necessary to unweight the ladder at the same time as adjusting. The present invention provides opposed locking brackets so that adjustment can be made by releasing a locking plate on just one bracket.

摘要： A horizontal support member in the form of rod, pipe or tube is disposed transverse to and displaced from a rigid or utility pole proximate a messenger cable supporting a cable. The support member is supported on and a part of a projecting arm extending outwardly from a bracket attached to the utility pole. The support member is further provided with flanges on the ends thereof to prevent hooks on the end of a lineman's ladder from slipping off the ends of the support member. The support member is long enough not only to provide engagement for both hooks of the lineman's ladder but also could be extended so that the ladder hooks cannot slide off the support member as long as the hooks of the lineman's ladder are astraddle the projecting arm. The projecting arm is of sufficient length to position the top of the ladder below the front face of an electrical equipment cabinet which may be hung on and bolted to a pole bracket. The positioning of the ladder thus further places a lineman at a convenient and comfortable working position relative to an electrical equipment cabinet or other apparatus that may be attached to the pole or to the pole bracket. The pole bracket is also useful to attach the invention to a wall, tower or trestle or other structure.

摘要翻译： 杆，管或管形式的水平支撑构件横向于刚性或电线杆设置，靠近支撑电缆的信使电缆。 支撑构件被支撑在从附接到电线杆的支架向外延伸的突出臂的一部分上。 支撑构件在其端部上还设置有凸缘，以防止线缆梯的端部上的钩从支撑构件的端部滑落。 支撑构件足够长，不仅可以为轮辋梯子的两个钩子提供接合，而且还可以延伸，使得梯子钩子不能从支撑构件滑下，只要轮辋梯子的钩子摆在突出臂上即可。 突出的臂具有足够的长度以将梯子的顶部定位在电气设备柜的前表面下方，该电气设备机柜的前表面可以悬挂在螺栓上并固定在杆架上。 梯子的定位因此进一步将线轮相对于可以附接到杆或杆支架的电气设备柜或其他设备将线员放置在方便和舒适的工作位置。 杆支架也可用于将本发明附接到墙壁，塔架或支架或其他结构。

摘要： A ladder attachment for supporting a ladder in a substantially upright position while suspending the top end of the ladder a predetermined distance from a vertical surface includes an elongated central portion attachable to each side rail of the ladder. A pair of diverging arms are pivotably attached to the central portion each of which can be selectively repositioned relative thereto with a removable locking pin. A collapsible cross member interconnects the arms. Each end of the cross member is selectively positionable along the length of the corresponding arm. An elongated translatable shaft interconnects the central portion and the cross member to adjust the spacing between the arms.

摘要： A safety device for a ladder, as embodied by the invention, is applied to a ladder that comprises side rails and a plurality of rungs interconnecting the side rails. The safety device comprises a plurality of side safety supports that are stored in their stored position in one rung of the plurality of rungs. The side safety supports are extendible from the one rung to a stabilizing extended position in which the side safety stabilizers are in contact with a supporting surface. Thus, the ladder safety device provides lateral stabilizing support for the ladder.

摘要： A process for manufacturing ladders comprises the following steps: arranging a plurality of rungs (2) of a material comprising a plurality of reinforcing fibers (2a) associated with a binding resin (2b) and each having at least one coupling portion (2c); arranging at least one primary upright length (3), preferably of a material comprising a plurality of reinforcing fibers (3a) associated with a binding resin (3b); mechanically linking the coupling portions (2c) of the rungs (2) to corresponding engagement regions (3c) of the primary upright length (3). The linking step involves bringing at least one of the binding resins (2b, 3b) to the fluid phase at least close to the engagement regions (3c) and/or the coupling portions (2c). The binding resins (2b, 3b) are thermoplastic polymeric materials and the step of bringing the binding resins (2b, 3b) to the fluid phase takes place by melting of the binding resins (2b, 3b). The binding resins (2b, 3b) are chemically similar to each other and they are preferably identical with each other.

摘要： A ladder leveler is disclosed in which two pivoting arms are mounted on a base plate to provide a self-adjusting and infinitely adjustable device. The two arms cooperate with a movable locking member or tumbler which is mounted between the arms and shaped to permit the arms to self adjust for uneven ground and lock the arms against movement when weight is placed on the ladder. The device may be readily secured to and removed from the base of a ladder without extensive disassembly.

摘要： A stair step of the plate-shaped step type comprises plate members bent downwards from the stepping surface at all four rims. The plate members are welded together at the corners where they abut one another. The plate members at the front and rear rims are rolled over to form cylindrical pipes, such that the plate member at the front rim is rounded at the bottom, thereby preventing jamming of the foot between the steps. The cylindrical pipes are filled with a foamed insulating material, such as polyurethane foam.
