Abstract

A work platform system having a first work platform. The system having a first bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly. The system having a second work platform. The first end of the second scaffold is disposed on the first bracket and the second bracket with the first bracket and the second bracket extending between the first rung of the third leg assembly and the second scaffold. A method for using a work platform system.

First claim

The invention claimed is:

1. A work platform system comprising:
a first work platform comprising:
a first scaffold having a first end and a second end and a plane upon which a user can stand;
a first leg assembly rotatably attached with bolts to the first end of the first scaffold having a first rail and a second rail and a rung attached to the first rail and the second rail, the first leg assembly in a folded position relative to the first scaffold and essentially in parallel the plane of the first scaffold;
a second leg assembly rotatably attached with bolts to the second end of the first scaffold, the second leg assembly in an open position relative to the first scaffold and essentially perpendicular to the plane of the first scaffold;
a first bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly;
a second bracket attached to the first scaffold and extending below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly; and
a second work platform comprising:
a second scaffold having a first end and a second end and a plane upon which the user can stand;
a third leg assembly rotatably attached with bolts to the first end of the second scaffold having a first rail and a second rail and a rung attached to the first rail and the second rail of the third leg assembly, the third leg assembly in an open position relative to the second scaffold and essentially perpendicular to the plane of the second scaffold, the first end of the second scaffold disposed on the first bracket and the second bracket with the first bracket and the second bracket extending between the first rung of the third leg assembly and the second scaffold, the first bracket and the second bracket disposed on the first rung of the third leg assembly, the first work platform locked to the second work platform through the first and second brackets engaging with the second scaffold and the rung of the third leg assembly; and
a fourth leg assembly rotatably attached with bolts to the second end of the second scaffold, the second leg assembly of the second scaffold in an open position relative to the second scaffold and essentially perpendicular to the plane of the second scaffold.

2. The system of claim 1 wherein no pins or bands or any additional components are needed to lock the first work platform with the second work platform.

3. The system of claim 2 wherein the first scaffold has a first crossbar disposed under the first scaffold along a length of the first scaffold and a second crossbar disposed under the first scaffold along a length of the first scaffold in parallel and spaced relation with the first crossbar, the first bracket bolted to the first crossbar and the second bracket bolted to the second crossbar.

4. The system of claim 3 wherein the first bracket has a first portion which is somewhat rectangularly shaped and has a bolthole through which a bolt extends to bold the first bracket to the first crossbar, a second portion which is somewhat rectangularly shaped and extends downward at an angle between 20° and 70° from the first portion, and a third portion that is somewhat rectangularly shaped that extends from the second portion essentially in parallel with the first portion, the third portion extending between the rung of the third leg assembly and the second scaffold and is disposed on the rung of the third leg assembly and on which the first end of the second scaffold is disposed.

5. The system of claim 3 wherein the third portion has a free end that flares outward.
