Stepladders and related methods
View Patent ↗Stepladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a top cap, a first assembly and a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with the top cap. The second assembly includes at least one rail pivotally coupled with the top cap. The first assembly and second assembly are configured to be displaced relative one another such that the stepladder is selectively positionable between a first, deployed state and a second, collapsed state. The first assembly, the second assembly and the top cap are cooperatively configured such that the at least one rail of the second assembly is at least partially nested within an envelope defined by the pair of spaced apart rails of the first assembly with the step ladder is in a collapsed state.
1. A stepladder comprising:
a first assembly having a pair of spaced apart rails, the rails exhibiting a first depth between an exterior edge and an opposing interior edge thereof;
a second assembly having a pair of spaced apart rails, the rails exhibiting a second depth between an interior edge and an opposing exterior edge thereof, the second assembly being pivotally positionable relative to the first assembly between a first, deployed state and a second, collapsed state, wherein a total depth of the stepladder when in the collapsed state is less than the sum of the first depth and the second depth;
a pair of hinged spreaders, each hinged spreader having a first component pivotally coupled with the first assembly and a second component pivotally coupled with the second assembly, wherein, when the stepladder is in a deployed state, the second component extends from the rails of the second assembly, beyond a hinge connecting the first component and the second component, and to a location adjacent the rails of the first assembly; and
at least one shoulder adjacent the first assembly configured to engage at least one of the second components when the ladder is in the deployed state.
2. The stepladder of claim 1 , further comprising a top cap, wherein the first assembly is pivotally coupled with the top cap and wherein the second assembly is pivotally coupled with the top cap.
3. The stepladder of claim 1 , further comprising a pair of struts, each strut having one end pivotally coupled with an associated hinged spreader and another end pivotally coupled with at least one of the second assembly and a top cap.
4. The stepladder of claim 3 , wherein the pair of struts extend substantially parallel to the rails of the first assembly when the ladder is in the first, deployed state.
5. The stepladder of claim 4 , further comprising a pair of handles coupled with the second components of the pair of hinged spreaders.
6. The stepladder of claim 4 , wherein the at least one shoulder is associated with at least one of the first assembly and the pair of hinged spreaders.
7. The stepladder of claim 1 , wherein the total depth of the stepladder when in the collapsed state is approximately equal to the first depth exhibited by the rails of the first assembly.
