Folding elevated working platform
Elevated work platform apparatuses, as well as associated methods, are provided. One elevated platform apparatus comprises a first assembly having a pair of rails coupled with a plurality of rungs, a second assembly hingedly coupled with the first assembly, a platform pivotally coupled with the first assembly and configured to extend to, and engage a portion of, the second assembly. The apparatus further includes a cage associated with the platform. The cage may include a guard structure including a pair of gates. A locking mechanism may be associated with the platform and include a latch member for engagement with a cross-member of the second assembly. Actuation of the locking member may include a “pulling” action by a user standing in front of the apparatus and reaching between the two rails of the first assembly.
1 . An elevated platform apparatus comprising:
a first assembly having a first pair of rails coupled with a plurality of rungs;
a second assembly having a second pair of rails and a cross member extending between and coupled to the second pair of rails, the second assembly being pivotally coupled with the first assembly, the first assembly and second assembly being displaceable between a deployed state and a collapsed state;
a platform pivotally coupled to the first assembly, the platform having a deck with an upper surface that is substantially coplanar with an upper surface of an uppermost rung of the plurality of rungs when the first and second assemblies are in the deployed state;
a latch mechanism associated with the platform, the latch mechanism including a latch member configured to be selectively horizontally slidably displaced away from the cross member and toward the uppermost rung to disengage the latch member from the cross member;
a cage associated with the platform, the cage including a guard structure pivotally coupled to the first pair of rails.
2 . The apparatus of claim 1 , wherein the latch mechanism is positioned in an opening formed in the deck of the platform.
3 . The apparatus of claim 2 , wherein the latch mechanism includes a first body member fixed to the deck and a second body member slidably coupled with the first body member, the second body member including the latch member.
4 . The apparatus of claim 3 , further comprising a biasing member positioned between the first body member and the second body member, the biasing member biasing the second body member toward the cross member.
5 . The apparatus of claim 4 , wherein the second body member includes an undulating surface for engagement by a user's fingers.
6 . The apparatus of claim 5 , wherein the latch member includes a ramped surface configured to engage the cross member and displace the second body member when the first and second assemblies are transitioning from the collapsed state to the deployed state.
7 . The apparatus of claim 1 , wherein the guard structure comprises a gate member including a cammed surface configured to engage a biased abutment member coupled with the guard structure.
8 . The apparatus of claim 1 , wherein the guard structure comprises a gate member configured to swing in a first direction upon a user stepping on to the platform from the first assembly and to swing to a closed position after the user is standing on the platform, the at least one gate also being limited from being displaced in a second direction, opposite the first direction, beyond the closed position.
