In some aspects, a ladder may be coupled to the base to enable access to the base when the base is oriented in the open position. In further aspects, a biasing component may be coupled between the elevated component and the base to bias the base during the rotational transition between the closed position and the open position. | 01-13-2011 |
20140311828 | MODULAR TREE-MOUNTABLE HUNTING STAND - A support frame rail with a central longitudinal axis is orthogonally coupled with a pivot beam. A support frame plate slidably couplable with the support frame rail includes an embedment projection. A hanger plate is fixable couplable with the support frame rail. A planar support platform is pivotably coupleable with the pivot beam. A saddle has a pommel portion, a saddle support portion, and a connecting straddle portion. A saddle bearing assembly defines a first rotation axis and is rotatably coupled with the saddle. A support frame bearing assembly defines a second rotation axis collinear with the central longitudinal axis. A pivot arm assembly is rigidly coupled with the saddle bearing assembly and the support frame bearing assembly. The straddle portion has a triangular cross-section, and enables adoption of an unsupported standing position, a partially supported standing position, or a weight-forward standing position, by a hunter straddling the straddle portion. | 10-23-2014 |
20150308190 | STEP LADDER - A ladder including a first frame, a second frame and a platform assembly. The first frame includes one or more fixed steps. The platform assembly includes a first platform pivotably coupled to the first frame, a second platform pivotably coupled to the first frame, a first linkage coupled between the second frame and one of the first platform and the second platform, and a second linkage coupled to the first platform and the second platform. The ladder is movable between a closed position and an open position | 10-29-2015 |

20160084002 | LADDER SUPPORT TRAY - An apparatus for supporting articles from a ladder comprises a horizontal tray member having a top and a bottom surfaces extending between front and rear edges and at least two inverted hooks secured to the rear edge of the tray member wherein each of the inverted hooks are sized to be selectably attachable to a first horizontal ladder member. The apparatus further comprises a pair of support legs extending from the horizontal tray member, each support leg including a foot at a distal end thereof to engage a support surface. A kit may also be provide comprising the tray and at least one extension bar receivable within a bore of a ladder rung so as to extend to a side thereof. | 03-24-2016 |
