Abstract:
1. A ladder shelf system ( 100 ) for adding a generally planar rectangular shelf ( 200 ) proximal to a top of a step ladder ( 110 ), wherein said system ( 100 ) comprises: (a) the generally planar rectangular shelf ( (b) a step engagement member ( wherein the step engagement member posterior side ( 340 ) is disposed flush with the shelf posterior end ( 240 ), wherein the step engagement member ( 300 ) traverses the rectangular shelf ( 200 ) from the shelf first side ( 250 ) to the shelf second side ( 260 ), wherein the step engagement member top surface ( 310 ) lies on a plane, Plane A ( 400 ), parallel to a plane, Plane B ( 410 ), wherein the shelf top surface ( 210 ) lies upon Plane B ( 410 ), wherein the step engagement member ( 300 ) comprises a step engagement member depth ( 380 ) extending from about the step engagement member anterior side ( 330 ) to about the step engagement member posterior side ( 340 ), the step engagement member depth configured to be equivalent to a depth of a top step interior cavity extending from about a top step anterior internal edge ( 126 ) to about a top step posterior internal edge ( 128 ), wherein the step engagement member ( 300 ) is adapted to fit inside the top step interior cavity ( 122 ); wherein a step engagement member height ( (c) a generally planar rectangular non-slip pad ( (d) a locking lever ( wherein the locking lever ( 600 ) comprises a first clamping member ( 640 ) disposed at an intersection of the first leg ( 610 ) and a horizontal cross member first side ( 632 ) of the horizontal cross member ( 630 ), wherein the locking lever ( 600 ) comprises a second clamping member ( 650 ) disposed at an intersection of the second leg ( 620 ) and a horizontal cross member second side ( 634 ) of the horizontal cross member ( 630 ), wherein the first clamping member ( 640 ) is disposed at a perpendicular angle to the first leg ( 610 ), wherein the first clamping member ( 640 ) lies on a same plane, Plane C ( 420 ), as the first leg ( 610 ), wherein the first clamping member ( 640 ) extends out and away from the horizontal cross member ( 630 ), wherein the second clamping member ( 650 ) is disposed at a perpendicular angle to the second leg ( 620 ), wherein the second clamping member ( 650 ) lies on a same plane, Plane D ( 430 ), as the second leg ( 620 ), wherein the second clamping member ( 650 ) extends out and away from the horizontal cross member ( 630 ), wherein the locking lever is moveable between a first unlocked position and a second locked position, wherein the first clamping member ( 640 ) and the second clamping member ( 650 ) lie on a plane, Plane E ( 440 ), perpendicular to the shelf top surface ( 210 ) and said plane B when in the first unlocked position, and wherein the first clamping member ( 640 ) and the second clamping member ( 650 ) lie on said Plane A ( 410 ) when in the second locked position; and (e) a recess ( wherein the shelf bottom surface ( 220 ) is configured to be positioned on the step ladder horizontal support ( 130 ) as the step engagement member ( 300 ) is disposed in the top step interior cavity ( 122 ), wherein the locking lever ( 600 ) is configured to be moved to the second locked position which is configured to position the first clamping member ( 640 ) and the second clamping member ( 650 ) on an exterior top step top surface ( 124 ), wherein the rectangular shelf ( 200 ) is configured to be on the step ladder horizontal support ( 130 ) in a generally level position.
