摘要： The ladder illuminates the immediate area and itself. The ladder improves safety by strategically adding multiple light sources to the ladder, thereby illuminating the areas around the ladder. Light emitting diodes (LEDs) may be mounted in several strategic locations, including: in-board and out-board of the end cap, under each rung, and out-board on both rails facing the base of the building when the ladder is correctly placed with a rechargeable battery supply.

摘要： An agility ladder has a plurality of rungs including first and second rungs. A left link assembly has ends pivotally attached to left ends of the first and second rungs, and a right link assembly has ends pivotally attached to right ends of the first and second rungs. The left and right link assemblies each include first and second links having equal lengths, with the first and second links joined at a link pivot joint which allows the first and second links to form an angle between them of less than 180 degrees.

摘要： Apparatus and methods for supporting a ladder are provided. Some embodiments may include a ladder. Such a ladder may include an engagement member for engaging a structure. The ladder may also include a telescoping member. The telescoping member may include an outer member and an inner member. The outer member may preferably be slideably engaged to the inner member. The ladder may further include at least one locking member for fixing the position of the outer member with respect to the position of the inner member. The telescoping member may preferably be hingedly attached to the ladder via a rotatable rung for attaching to the outer member, or hingedly attached to the ladder using any other suitable device. In one configuration, the outer member may be stored substantially parallel to a longitudinal axis of the ladder. In another configuration, the support engagement member may engage the structure.

摘要： The instant application discloses, among other things, a Floating Ladder. In one embodiment, it may comprise a ladder capable of attaching to any object, such as a fixed or floating dock, for instance. Floating Ladder may include a floatation device at its base, which may allow the ladder to ascend above the surface of the water when the ladder is not in use. This may prevent the Floating Ladder from sustaining damage from any natural or artificial substance, object, or organism, which may render the ladder unsafe or unusable, for instance. In another embodiment, Floating Ladder may include multiple sections to allow a user to telescope the ladder further into the water when necessary.
摘要翻译： 本申请尤其公开了一种浮动梯子。 在一个实施例中，其可以包括能够附接到例如固定或浮动码头的任何对象的梯子。 浮动梯可包括在其底部的漂浮装置，当梯子不使用时，这可能允许梯子上升到水面之上。 这可能会阻止浮式梯子从任何天然或人造物质，物体或生物体受到损害，从而使梯子不安全或不可用。 在另一个实施例中，浮动梯可以包括多个部分，以允许使用者在必要时将梯子进一步伸入水中。

摘要： The present invention relates to ladders and, more particularly, various configurations of ladders including straight and extension ladders, as well as to methods relating to the use and manufacture of such ladders. In accordance with one embodiment of the present invention, a ladder is provided that includes a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. The ladder also includes a pair of lateral support members, wherein each support member is selectively displaceable in a lateral direction relative to an associated rail. Additionally, the ladder includes a pair of adjustable legs, each leg having a first end slidably coupled to an associated rail of the first pair of spaced apart rails and being slidably coupled to an associated lateral support member.

摘要： A ladder support device removably securable to the hitch receiver of a vehicle. The ladder support device comprises a frame having adjustable ground engaging legs. The frame includes a pivoting arm to be removably secured to the hitch of a vehicle to allow the frame to be positioned in a desired orientation relative to the vehicle. The frame includes a pair of brackets for receiving the feet of an extension ladder therein. Further, the frame comprises a pair of telescopic support arms that extend upward from the frame and that can be secured to a portion of the extension ladder so as to secure the ladder in an upright, angled orientation without having to rest the ladder against a support surface, such as the side of a building.
