Abstract
A scaffold having a structure assembly. The scaffold has a frame attached to the assembly. The frame having a deck upon which a user can stand that is disposed inside the rectangle. The deck has a plans table. The plans table has a closed position in which the plans table is flat and can support a weight of a user standing on the plans table, and has an open position in which the plans table is at an angle on which plans, drawings or documents can be placed on the plans table for viewing by a user standing on ground. A scaffold having connectors. A method of using a scaffold. A method for connecting a first scaffold to a second scaffold. A method for making a scaffold with connectors. A method for making a scaffold having a plans table.
Claims20
A scaffold comprising:
- a structure assembly having a first vertical leg at a first corner of the structure assembly, a second vertical leg at a second corner of the structure assembly, a third vertical leg at a third corner of the structure assembly and a fourth vertical leg at a fourth corner of the structure assembly;
- the first and second vertical legs having at least one horizontal crossbar between them and the third and fourth vertical legs having at least one horizontal crossbar between them, the first, second, third and fourth corners defining an area;
- and
- a frame attached to the structure assembly, the frame having a deck disposed at least partially inside the area, the deck including a plans table, the plans table having a closed position in which the plans table is in line with a remainder of the deck and can support a weight of a user standing on the plans table, and having an open position in which the plans table is at an angle with respect to the remainder of the deck such that plans, drawings or documents can be placed on the plans table at an angle for viewing by a user standing on ground;
- and
- the deck further comprising a door that has a first position in which the door is at an angle relative to the remainder of the deck and the user can climb onto the deck through the door in the first position, and that has a second position in which the door is in line with the remainder of the deck, forms a plane with the plans table when the plans table is in the closed position, and can support the weight of a user standing on the door.
