Abstract
A ladder walkthrough assembly can include a ladder; and a ladder walkthrough including a frame and a guide post, the frame coupled to the ladder the guide post coupled to the frame and extending upwards above a top end of the ladder. The frame can include a first bracket coupled to a first side rail of the ladder and a second bracket coupled to a second side rail of the ladder.
Claims21
A ladder walkthrough assembly comprising:
- a ladder comprising a plurality of rungs between a pair of rails, each rail defining a first ladder surface on an outer surface of the rail and a second ladder surface on an outer surface of the rail on an opposite side of the rung from the first ladder surface, a distance on the rail between the first ladder surface and the second ladder surface defining a thickness of the ladder;
- and
- a ladder walkthrough comprising:
- a frame comprising a bracket extending between an upper clamp and a lower clamp coupled to the ladder, the upper clamp and the lower clamp each coupled to the first ladder surface and each comprising a tightener within an angled slot oriented diagonally to the second ladder surface, wherein the tightener slides through the angled slot to accommodate the thickness and contacts the second ladder surface;
- and
- a guide post coupled to the first ladder surface of the ladder, the guide post coupled to the bracket of the frame and extending upwards above a top end of the first ladder surface of the ladder.
A ladder walkthrough assembly comprising:
- a ladder comprising a first ladder surface and a second ladder surface opposite the first ladder surface, a distance from the first ladder surface to the second ladder surface defining a thickness of the ladder;
- and
- a ladder walkthrough comprising at least one guide-post assembly, the at least one guide-post assembly comprising a guide post received in a frame on the first ladder surface of the ladder, guide post assembly comprising a bracket extending between an upper clamp and a lower clamp, the upper clamp and the lower clamp each coupled to the first ladder surface and each comprising a tightener within an angled slot oriented diagonally to the second ladder surface, wherein the tightener slides through the diagonal of the angled slot to accommodate the thickness and contacts the second ladder surface, the guide post secured to the bracket and the upper clamp and the lower clamp receiving the ladder.
A method for using a ladder walkthrough assembly comprising a ladder walkthrough and a ladder comprising a first ladder surface and a second ladder surface opposite the first ladder surface, a distance between the first ladder surface and the second ladder surface defining a thickness of the ladder, the method comprising:
- coupling the ladder walkthrough to the ladder comprising:
- engaging a first frame comprising a bracket between an upper clamp and a lower clamp of the ladder walkthrough with the first ladder surface of a first side rail of the ladder, the upper clamp comprising a tightener within an angled slot oriented diagonally to the second ladder surface, wherein the tightener contacts the second ladder surface;
- and
- engaging a second frame comprising a bracket between an upper clamp and a lower clamp of the ladder walkthrough with the first ladder surface of a second side rail of the ladder, the lower clamp comprising a tightener within an angled slot oriented diagonally to the second ladder surface, wherein the tightener contacts the second ladder surface;
- and
- positioning the upper clamps and lower clamps of the first frame and the second frame, respectively, on the first side rail and the second side rail of the ladder and the ladder walkthrough assembly within the bracket of the first frame and the bracket of the second frame to secure the ladder walkthrough assembly against a structure.
