Abstract:
1. A climbing apparatus that rests on a surface comprising: a flip ladder that can move between a straight configuration, a stepladder and a closed configuration; and a tray defining a plane, the tray being attached to the flip ladder and moveable between a stowed position and an open position, the tray automatically and simultaneously pivots from the open position to the stowed position when the ladder pivots from the step ladder configuration to the straight configuration so that the tray is in the stowed position while the flip ladder is in the straight configuration and the tray is in the open position while the flip ladder is in the step ladder configuration, the tray and tray plane are essentially parallel with a major length of the flip ladder in the stowed position, and the tray and tray plane are essentially parallel to the surface when in the open position while the ladder is in the step ladder configuration; and the flip ladder has a front section having steps, a rear upper section having rungs, hinges directly connecting the front section and rear upper section, and a pivot rod that extends through the tray and pivotally attaches the tray to the rear upper section, the tray is disposed within a right rear rail and a left rear rail of the rear upper section while the flip ladder is in the straight configuration so as to allow a user to climb or descend the ladder without hindrance from the tray, and when the flip ladder is in the stepladder configuration it rests on the surface so that the front section and the right and left rear rails of the rear upper section contact the surface; and the flip ladder can be locked in the stepladder configuration and the flip ladder can be locked in the straight configuration with the hinges, and the rungs on the rear upper section are doubled sided, and two tray links, through which at a first end of each tray link, respectively, the tray is pivotally attached at respective link pivots, and a second end of each tray link, respectively, is attached to a respective hinge of the hinges, and studs, wherein each respective tray link has a respective slot, and the tray links are connected to the hinges respectively through a respective stud of the studs which extend within the slots respectively, the slots allow the links to pivot and slide relative to the front section, and when the tray is in the open position it directly rests on top of a highest rung of the rungs of the rear upper section, and when the tray is in the stowed position, projections of the tray directly rest against the highest rung.
