Ladders, foot mechanisms for ladders, and related methods
Various embodiments of ladders, ladder legs, ladder feet, foot mechanisms for ladders, and related methods are provided herein. In one embodiment, a foot is pivotal relative to a leg or rail of the ladder between a first position and at least a second position. A biasing force is applied to the foot to maintain the foot in either of the user-selected positions until a force is applied to pivot the foot to another position. In one embodiment, the foot mechanism maintaining the foot at a desired position may include a pair of pins that couple the foot to another component (e.g., a housing member, an insert member or a rail of the ladder). At least one of the two pins may be displaceable relative to the other pin during pivoting of the foot.
Stepladder folding leg
A folding leg for a stepladder is disclosed. The folding leg allows the width of the stepladder base to be narrowed when in the stored orientation and widened while in an in-use orientation.
TOP CAP FOR ARTICULATING LADDER
Ladders and ladder accessories for articulating ladders are mountable to an upper rung of the ladder and can remain attached to the upper rung while the ladder articulates between collapsed, straight, and step ladder configurations without binding or engaging other rungs. The accessories can be top caps configured to hold tools and parts while the user climbs and stands on the ladder. The accessories can be removed from the ladder without damage to the accessory or the ladder, thereby enabling retrofitting ladders with the accessory or moving the accessory to different rungs or positions on the same ladder. Some accessories can have more than one body portion, and a portion can therefore pivot relative to another portion to enlarge the working platform offered by the accessory and to provide additional surfaces for temporarily supporting the accessory parts on the ladder rungs.
Telescoping ladder
A telescoping ladder includes first and second telescoping ladder racks each having a top portion and including an outer ladder rack having first and second outer legs having interior surfaces that are sliding surfaces; and an inner ladder rack having a first and second inner legs having a sliding surface that slidably engages the sliding surface of the first outer leg along the length thereof, and the second inner leg having a sliding surface that slidably engages the sliding surface of the second outer leg along the length thereof. The top portions are pivotally connected to form a structure that articulates to open and close the ladder. The outer and inner ladder racks are configured as elongated hollow tubes that have a cross section of a closed tube having a protuberance extending therefrom. The outer legs have lateral support legs having protruding ribs to form a stabilizing support structure.
7000 series aluminum alloy ladder, multipurpose ladder and method
A ladder and a multipurpose ladder whose rungs and rails are made out of 7000 series aluminum alloy and which has a duty rating of at least 250 lbs. A method for producing a ladder. A method for using a ladder.
Ladder Assembly
A ladder assembly having a front frame having a first pair of spatially disposed legs, a plurality of rungs extending between the first pair of legs, and a pivot bracket mounted at the top of the front frame, a rear frame having a second pair of spatially disposed legs, one or more rungs extending between the second pair of legs, and a fixed bracket mounted at the top of the rear frame, wherein the pivot bracket is attached to the fixed bracket via a single point pivot bracket system configured to pivotally connect the front frame and the rear frame, a folding bracket system configured to keep a correct angle between the front frame and the rear frame, thereby allowing the rotational movement of the legs.
Ladder Stabilization Assembly
A ladder stabilization assembly for inhibiting a ladder from tipping laterally includes a pair of eyebolts that can each be attached to a respective leg of a ladder. A tube is insertable through each of the eyebolts such that the tube is oriented to extend along a horizontal axis. In this way the tube is aligned with a support surface on which the ladder is standing to inhibit the ladder from tipping laterally.
Ladder anchor apparatus
A ladder anchor apparatus for securing a ladder in place includes a pair of arms each having a straight portion and a hooked portion. Each of the arms has a pivot aperture. The pair of arms is configured to be selectively engageable within a pair of ladder holes of a pair of legs of a ladder. A hollow pivot rod is coupled to the pair of arms and extends through the pivot aperture of each arm. The pair of arms is pivotably coupled around the pivot rod. A mounting pin is slidingly engageable through the pivot rod and is configured to be inserted into the ground to secure the apparatus in place. An eye hook and a safety chain are coupled to a left arm of the pair of arms. The safety chain prevents the pair of arms from pivoting open when engaged with the eye hook.
LEVELING AND STABILIZING ACCESSORY FOR LADDERS
Described herein is an improved ladder leg extender and leveler assembly including an elongate frame member or structure which can be fixed in a flush relation to a ladder leg side rail and secured to at least two ladder rungs. Each elongate frame member includes a slidably engage elongate leg extension which engages a height adjustment member or actuator that is located on a surface of the elongate frame member. The height adjustment member operates via a spring actuated pin or rod which engages a series of pre-set slots on the elongate leg extension to adjust the height of the ladder on either side. Also, a pivoting ladder stabilizing element which is extendable. This greatly provided additional stability and security.
