Ladders, ladder components and related methods
Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.
1. A ladder, comprising:
a first pair of rails including a first rail and a second rail;
an inner member slidably coupled with the first rail; and
a locking mechanism, including:
a bracket coupled to the first rail and defining an opening;
a lever positioned adjacent to the bracket, the lever being pivotable about a first axis positioned laterally offset from and entirely external to the first rail, the lever being longitudinally fixed in position relative to the first rail;
an engagement protrusion coupled to the lever and movable with the lever about the first axis between a first position and a second position, wherein, when the engagement protrusion is in the first position, the engagement protrusion is disposed at least partially within the opening and engages the inner member, and wherein, when the lever is in the second position, at least a portion of the engagement protrusion is withdrawn from the opening and the locking mechanism is disengaged from the inner member;
a spring biasing the engagement protrusion to the first position;
a pin extending through the spring, the bracket, and the lever; and
a cover disposed about the engagement protrusion.
2. The ladder of claim 1 , wherein the cover at least partially surrounds the engagement protrusion.
3. The ladder of claim 1 , wherein the cover laterally conceals the engagement protrusion.
4. The ladder of claim 1 , wherein the cover is positionable against the bracket.
5. The ladder of claim 1 , wherein the engagement protrusion is connected to the lever via an axle.
6. The ladder of claim 5 , wherein the cover comprises a slot allowing the axle to translate relative to the cover when the lever pivots between the first position and the second position.
7. The ladder of claim 5 , wherein the axle extends through each of the lever, the cover, and the engagement protrusion.
8. The ladder of claim 1 , wherein the lever comprises a lower portion displaceable toward the first rail in response to the lever pivoting about the first axis as the engagement protrusion moves from the first position to the second position.
9. The ladder of claim 1 , wherein the lever comprises an upper portion displaceable from away from the first rail in response to the lever pivoting about the first axis as the engagement protrusion moves from the first position to the second position.
10. The ladder of claim 1 , wherein the first axis extends through the pin.
11. A ladder, comprising:
a pair of ladder rails interspaced by a plurality of ladder rungs; and
a rocking mechanism disposed along at least one ladder rail of the pair of ladder rails, the rocking mechanism comprising:
a rotatable lever comprising a first end portion and a second end portion opposite the first end portion, the second end portion having a depressible handle;
a bracket fixed to and at least partially extending laterally away from the at least one ladder rail, wherein with the depressible handle depressed, the bracket is fixed in place relative to the at least one ladder rail;
a pin extending through the rotatable lever between the first end portion and the second end portion and extending through the bracket, the rotatable lever being rotatable about an axis extending through the pin and through the bracket, the axis being entirely external to the at least one ladder rail and fixed in place relative to the bracket;
an engagement protrusion coupled to the rotatable lever at the first end portion;
a spring biasing the first end portion toward the at least one ladder rail of the pair of ladder rails and biasing the second end portion away from the at least one ladder rail of the pair of ladder rails, wherein the pin extends through the spring; and
a sleeve wall, wherein the engagement protrusion is positioned within the sleeve wall;
wherein the engagement protrusion is movable relative to the sleeve wall.
12. The ladder of claim 11 , wherein the bracket defines an opening sized and shaped for the engagement protrusion to move at least partially through the opening.
13. The ladder of claim 12 , wherein the engagement protrusion is disposed at least partially within the opening when the rotatable lever is in a rest position relative to the at least one ladder rail of the pair of ladder rails.
14. The ladder of claim 12 , wherein the engagement protrusion is at least partially withdrawn through the opening when the rotatable lever is in an actuated position relative to the at least one ladder rail of the pair of ladder rails.
15. The ladder of claim 11 , further comprising an additional pin coupling the engagement protrusion and the first end portion.
16. The ladder of claim 15 , wherein the additional pin further couples the sleeve wall to the rotatable lever.
17. The ladder of claim 11 , wherein the sleeve wall limits lateral exposure of the engagement protrusion while the rocking mechanism is in an actuated position relative to the at least one ladder rail of the pair of ladder rails.
18. A ladder, comprising:
a pair of ladder rails spaced apart by and coupled to a plurality of ladder rungs; and
a locking mechanism disposed along at least one ladder rail of the pair of ladder rails, the locking mechanism comprising:
a bracket coupled to the at least one ladder rail and defining an opening;
a cover contacting the bracket;
an engagement protrusion disposed within the cover and at least partially disposed within the opening;
a lever coupled to each of the bracket, the cover, and the engagement protrusion,
wherein the lever comprises an upper portion and a lower portion, the lower portion having a depressible handle;
wherein a first pin extends through and is directly pivotally coupled with the lever, the cover, and the engagement protrusion; and
wherein the lever is coupled to the bracket via a second pin positioned between the upper portion and the lower portion; and
a spring disposed about the second pin.
19. The ladder of claim 18 , wherein the spring biases the engagement protrusion through the opening.
