Abstract:
A ladder leg support apparatus for supporting a ladder on a stairway, said apparatus comprising:a support member having a base plate, opposing upstanding inner side walls extending from said base plate, and an upstanding inner back wall extending from said base plate intermediate said inner side walls, said inner side walls and said inner back wall defining an interior space with an open top and an open front; a plurality of opposed pairs of support flanges positioned along said inner side walls; a support plate selectably positioned atop corresponding support flanges and adapted to support a leg of a ladder at a selected height above said base plate of said support member; said support member comprising: opposed outer side walls, each outer side wall being inclined and extending between a respective side edge of said base plate and a top edge of a respective inner side wall; an outer back wall being inclined and extending between a longitudinal edge of said base plate and a top edge of said inner back wall; an auxiliary side panel having a first edge pivotally coupled to a lower edge of a respective outer side wall for pivotal movement between a first configuration bearing against said respective outer side wall and a second configuration coextensive with a longitudinal plane defined by said base plate, said auxiliary side panel defining a plurality of apertures; and a support leg having a plurality of threads and a base for contact with a support surface, said support leg adapted to be threadably positioned in a selected aperture, whereby a rotation of said support leg in one direction increases the length of said support leg depending from said auxiliary side panel to increase the height of said auxiliary side panel relative to the support surface, a rotation of said support leg in an opposed direction decreases the length of said support leg depending from said auxiliary side panel to decrease the height of said auxiliary side panel relative to the support surface.
