Stabilized Ladder Assembly
A stabilized ladder assembly includes a step ladder that has a set of climbing legs and a set of support legs each is hingedly coupled to a top support. A pair of lateral supports is each pivotally disposed on the step ladder. Each of the lateral supports is positionable in a deployed position to engage a support surface for inhibiting the step ladder from tipping laterally on the support surface. Each of the lateral supports is positionable in a stored position having the lateral supports resting against the step ladder. A toolbox is suspended on the step ladder such that the toolbox is accessible to a user when the user climbs the step ladder. Additionally, the toolbox is oriented to extend along a vertical axis when the step ladder is positioned in a deployed position.
Adjustable ladders, ladder components and related methods
Ladders, ladder components, adjustment mechanisms and related methods are provided herein. In one embodiment, a ladder may include an adjustment mechanism for adjusting, for example, a leveler, a stabilizer, or any two relatively displaceable components of the ladder. The adjustment mechanism may include an actuating mechanism having a first structure and a second structure slidably disposed adjacent the first structure, the second structure having a plurality of engagement surfaces. A body is coupled with the first structure. At least two engagement pins are slidably displaceable relative to the body, wherein the plurality of engagement surfaces and the at least two engagement pins are arranged such that only a single engagement pin of the at least two engagement pins is in abutting engagement with an engagement surface of the plurality of engagement surfaces at one time. At least one biasing member is configured to bias the at least two engagement pins towards engagement with the engagement surfaces.
Ladder Leveler and Method
A ladder upon which a user climbs having a first rail. The ladder having a second rail. The ladder having rungs attached to the first and second rails upon which the user steps. The ladder having a first leveler attached to the first rail. The first leveler having a foot peg and a latch. When the user presses on the foot peg and the latch with the user's foot when the leveler is in an extended state, the first leveler moves into a retracted state. The ladder having a second leveler attached to the second rail. A method for a user to use a ladder. The method has the step of the user pushing with the user's foot against a foot peg and latch of a first leveler to cause the first leveler to move to a retracted state relative to a first rail of the ladder in which the first leveler is. There is the step of the user pushing only against the foot peg but not the latch with the user's foot when the leveler is in the retracted state causing the first leveler to move to an extended state relative to the first rail and be maintained in the extended state. A leveler which positively prevents inadvertent retraction of the leveler from an extended state to a retracted state. A ladder having a module with a first and second ladder leveler.
Ladder Support Attachment
A ladder support for attaching on a leg of a ladder. The ladder support attachment includes a pair of support members that removably secure to opposing legs of a ladder. Each support member includes an upper bar affixed to a lower bar about a hinge. The upper bar includes a first fastener on a second end of the upper bar and the lower bar includes a second fastener on a proximal end of the lower bar. The first and second fasteners removably secure to a leg of the ladder. The pair of support members can transition between a first position and a second position, where the first position is the upper and lower bars resting parallel to the leg of the ladder and the second position is the upper and lower bars forming a triangular shape with the leg where the lower bar rests flush with the ground.
UNIVERSAL STABILIZER DEVICE
A self stabilizing system which has an incompressible coil at least partially encompassed in a housing, and which controls a foot of a device to be stabilized. The coil abuts a plunger, which plunger is for allowing a user to selectably lock the elevation by use of a pin which fits within a plurality of annular grooves on the plunger. In a first embodiment, a pair of coils surround the plunger on either side and control a pair of feet, thus allowing automatic stabilization on an uneven surface. In a second embodiment, a single coil is controlled by a spring which abuts the plunger allowing a spring-loaded system for selecting an elevation to lock the plunger.
Ladder leveling and stabilizing assembly
The assembly includes a first arcuate tube attached to a ladder. A second arcuate tube is slidably disposed in the first arcuate tube. A lock subassembly is disposed on the first arcuate tube for limiting movement of the second arcuate tube relative to the first arcuate tube. A step lever extends along the first arcuate tube and is coupled with the lock subassembly. A first flange and a second flange each extend radially from the first arcuate tube. An actuating member defines a cam surface abutting the second flange. A bar extends through the flanges and attaches to the actuating member. The step lever attaches to the actuating member to move the actuating member and cause the cam surface to slightly deform the first arcuate tube about the second arcuate tube and engage the second arcuate tube. A foot is pivotably disposed at each end of the second arcuate tube.
STRETCHABLE LADDER
A stretchable ladder has two stretchable ladder racks, the top of the two stretchable ladder racks are pivoted together to a herringbone structure that can be open and closed, the stretchable ladder rack comprises an inner ladder rack and an outer ladder rack connecting together in stretching way, the inner ladder rack comprises two inner legs and an inner cross beam connecting the two inner legs, the outer ladder rack comprises two outer legs and an outer cross beam connecting the two outer legs, the inner leg is slidably connected to the outer leg, wherein the cross section of the inner leg and the outer leg is closed hollow tube shaped; two outer legs are respectively disposed at the outer side of the two inner legs, the inner cross beam of the inner ladder rack is disposed between the two outer legs of the outer ladder rack.
SAFETY LADDER
A ladder is disclosed having a six point base for improved stability and user center of gravity.
A STABILISER SYSTEM FOR A COLLAPSIBLE LADDER
A stabiliser system (150; 160; 170; 180) for use with at least one ladder tube (10, 12) of a collapsible ladder (1) wherein the collapsible ladder (1) comprises at least two ladder sections (6, 5a-5j) and where each ladder section comprises two ladder tubes (10, 12) arranged parallel to each other and interconnected by a rung (20) to form the respective ladder section, and where each ladder tube (10, 12) is telescopically inserted into a ladder tube (10, 12) of a lower ladder section to form the collapsible ladder (1) is provided. The stabiliser system (150; 160; 170; 180) comprises at least two bracket sections (110a-b, 112a-b; 120a-b, 122a-b) each arranged to receive a respective ladder tube (10, 12), and two elongated portions (130a-b) being connected to at least one bracket section (110a-b, 112a-b; 120a-b, 122a-b), wherein each elongated portion (130a-b) is configured to be arranged in a retracted position (71) and a deployed position (72), wherein in the retracted position (71) each elongated portion (130a-b) is arranged substantially parallel to the respective ladder tubes (10, 12).
FALL CONTROL LADDER
The invention is directed broadly to a ladder having a fall control system, comprising: a ladder; a tensioner mounted towards a bottom end of the ladder; a mount mounted towards a top end of the ladder; a cable that extends from the tensioner and over the mount in a looped configuration; and an arrestor movably engaged with the cable for coupling a user to the cable, wherein the tensioner has a locked configuration for holding tension on the cable to support a weight of the user and an open configuration for allowing the cable to pass through the tensioner.
