20100006375Portable Worker Safety Frame - A portable worker safety frame provides many of the benefits of a loading dock while enhancing worker safety. In one implementation, the safety frame provides a walking surface of adjustable height that may be placed adjacent to an arbitrary work surface of a transportation vehicle. The safety frame can provide a walking platform that has a similar length as the cargo bed itself, yet is portable by such conventional means as the forks of a lift truck. The portable worker safety frame also provides an overhead safety rail to which each worker may attach a safety harness cord.01-14-2010
20100025155Reusable Mud-Sill - A reusable mud-sill to replace the conventional wooden-mud-sills and to capture without the use of tools the small-metal-plate conventionally found at the bottom of scaffold legs. Mud-sills are used to interface the bottom ends of scaffold legs, or the like, to the ground and to provide reasonable ground pressure while inhibiting side movement of a leg. The reusable mud-sill captures a small-metal-plate with two fixed opposing side-blocks, a fixed overlapping-retainer, and a sliding overlapping-retainer that may be locked to the reusable mud-sill when the conventional small-metal-plate has been captured. The cooperating, capturing parts are all centrally placed on the top of a flat-plate that is significantly larger than the small-metal-plate.02-04-2010

182180100 Ladder 7
20100116592Adjustable Stepladder - A stepladder with four individually adjustable, self-locking rails so that the ladder can be placed on uneven terrain then safely adjusted to maintain level orientation. The ladder rails will consist of four pairs of outer and inner rails. Each outer and inner rail pair is designed with profiles that when brought together will lock into one another providing stability yet minimal friction. Each inner rail is held in place by a spring-loaded lever with attached hooks. The spring forces the hooks to be engaged with an adjustment bracket that is fixed to the outer rail. A foot will be fixed to the bottom of each inner rail. Each foot will have arched surfaces along 2 perpendicular horizontal axes so that consistent surface area contact is maintained with the ground regardless of the angle of the ground. On a level surface, when the ladder is in an un-adjusted state, the four inner rails are designed to be extended with respect to the outer rails providing equal distance between each step and reducing weight and production costs.05-13-2010
