摘要： Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a first and a second position. When tension is applied to the rope, the spring mechanism allows upwards or downwards movement of the fly section relative to the base section. When tension is removed from the rope, the spring mechanism slows or resists upwards or downwards movement of the fly section relative to the base section regardless of the fly section's position relative to the base section.

摘要： A climbing apparatus that rests on a surface includes a flip ladder that can move between a straight configuration and a stepladder configuration. The apparatus includes a tray having a plane attached to the flip ladder that moves with the flip ladder between the straight configuration where the tray plane is essentially parallel with the ladder in a stowed position and a stepladder configuration where the tray plane is essentially parallel with the surface in an open position. A method for climbing includes the steps of moving a flip ladder between a straight configuration and a stepladder configuration. There is the step of moving a tray having a plane attached to the flip ladder from a stowed position where the tray plane is essentially parallel with the ladder to an opened position where the tray plane is essentially parallel with the surface. There is the step of moving the flip ladder from the stepladder configuration to the straight configuration which causes the tray to move automatically into the stowed position.

摘要： A ladder rung plug is provided for preventing insect infestation of open ended ladder rungs, providing additional storage space, and selectively supporting items from the ladder. The plug assembly includes a ladder having a rung with an open end. A plug is provided having a first end, a second end, and a peripheral edge extending between the first end and the second end. The first end is insertable into the open end of the rung. Thus, the open end may be sealed by the plug. In an embodiment, a wall extends from the first end of the plug forming a storage compartment with an opening through the plug. A cap is selectively couplable to the plug to close the storage compartment.

摘要： A clip for maintaining a first side rail of a first ladder adjacent to a second side rail of a second ladder which is in series with the first side rail. The clip includes a first portion connected to a support element and a second portion connected to the support element. The first portion, second portion and support element are one continuous piece. The first portion defines a hooking engagement with the first side rail and the second portion defines a receiving engagement with the second side rail. The first and second portion opening from opposite sides of the support element, respectively, which conform to the portion of the respective side rail that it receives for removably and frictionally holding the respective side rails in a self-gripping and form-fitting manner such that the side rails are maintained adjacent and in series to each other so that no damage is possible to the ladders by relative movement of the side rails under dynamic conditions brought about by motion during transportation. A method for securely transporting a first ladder which defines a first plane for climbing and at least a second ladder which defines a second plane for climbing.
