Flip ladder with tray and method
View Patent ↗A climbing apparatus that rests on a surface includes a flip ladder that can move between a straight configuration and a stepladder configuration. The apparatus includes a tray having a plane attached to the flip ladder that moves with the flip ladder between the straight configuration where the tray plane is essentially parallel with the ladder in a stowed position and a stepladder configuration where the tray plane is essentially parallel with the surface in an open position. A method for climbing includes the steps of moving a flip ladder between a straight configuration and a stepladder configuration. There is the step of moving a tray having a plane attached to the flip ladder from a stowed position where the tray plane is essentially parallel with the ladder to an opened position where the tray plane is essentially parallel with the surface. There is the step of moving the flip ladder from the stepladder configuration to the straight configuration which causes the tray to move automatically into the stowed position.
1. A method for moving a flip ladder having a tray defining a tray plane, a front section with rungs that define a major plane and a rear section with rungs that define another major plane, wherein the two sections are pivotally hinged together to pivot between a stepladder configuration, a straight configuration and a closed configuration, the straight configuration is when the major planes of the two sections are coplanar, the stepladder configuration is when the two sections are in an A-shaped configuration so that the ladder can support itself on a surface, and the closed configuration is when the major planes of the two sections are in separate, parallel planes with respect to one another, the method for moving the flip ladder comprising the steps of:
moving the flip ladder from the straight configuration to the stepladder configuration;
moving the tray from a stowed position, where the tray plane is essentially parallel with one of the major planes of the two sections, to an opened position, where the tray plane is essentially parallel with the surface when the ladder is in the stepladder configuration;
moving the flip ladder from the stepladder configuration to the straight configuration, wherein moving the flip ladder from the stepladder configuration to the straight configuration causes the tray to move automatically and simultaneously into the stowed position from the opened position; and
moving the ladder to the closed configuration and the tray to the stowed position; and
opening the ladder from the closed configuration to the stepladder configuration and then to the straight configuration, wherein said opening does not cause the tray to move from the stowed to the opening position.
2. A method as described in claim 1 , wherein the ladder further has sliding tray links, pivotally attached to the tray at link pivots and to hinges which connect the front section and the rear upper section of the flip ladder, relative to the front section through slots of the tray links.
