Abstract
A work platform system having a first work platform. The first work platform having a first hook assembly and a first latch assembly. The system having a second work platform. The second work platform having a second hook assembly and a second latch assembly. The first work platform locked to the second work platform through the first hook assembly engaging with the second latch assembly and the first hook assembly in the use position. A method for using a work platform system. A method for producing a work platform.
Claims21
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 with 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 hook assembly slidingly attached to the first scaffold adjacent the first end which slides between a use position where the first hook assembly extends below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly and a stowed position where the first hook assembly is retracted below the first scaffold;
- a first latch assembly attached to the first scaffold adjacent the second end;
- 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 which is flat without objects on which the user can trip;
- 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 a closed position relative to the second scaffold and essentially in parallel to the plane of the second scaffold when the second scaffold is attached to the first scaffold;
- 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;
- a second hook assembly slidingly attached to the second scaffold adjacent the second end of the second scaffold which slides between a use position where the second hook assembly extends below and outward beyond the second scaffold between the first rail and the second rail of the fourth leg assembly and a stowed position where the second hook assembly is retracted below the second scaffold;
- and
- a second latch assembly attached to the second scaffold adjacent the first end of the second scaffold, the first work platform locked to the second work platform through the first hook assembly engaging with the second latch assembly and the first hook assembly in the use position.
A method for using a work platform system comprising the steps of:
- sliding a first hook assembly attached adjacent to a first end of a first scaffold into a use position where the first hook assembly extends below and outward beyond the first scaffold between a first rail and a second rail of a first leg assembly rotatably attached adjacent to the first end of the first scaffold from a stowed position where the first hook assembly is retracted below the first scaffold;
- placing a second latch assembly attached to a second scaffold adjacent a first end of the second scaffold on the first hook assembly in the use position;
- and
- pushing down on the second scaffold so the second latch assembly engages with the first hook assembly and locks the first work platform to the second work platform with the first scaffold coplanar with the second scaffold and forming a surface.
A method for producing a work platform comprising the steps of:
- attaching a track to an underside of a scaffold;
- fitting a hook assembly to the track so the first hook assembly so the hook assembly slides along the track from a stowed position into a deployed position, where the first hook assembly extends below and outward beyond the first scaffold between a first rail and a second rail of a first leg assembly rotatably attached adjacent to the first end of the first scaffold, and when the first hook assembly is in a stowed position, the first hook assembly is retracted below the first scaffold;
- and
- attaching a latch assembly to the bottom of the scaffold.
A 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 hook assembly slidingly attached to the first scaffold adjacent the first end which slides between a use position where the first hook assembly extends below and outward beyond the first scaffold between the first rail and the second rail of the first leg assembly and a stowed position where the first hook assembly is retracted below the first scaffold, the first hook assembly having a hook crossbar, and
- a first latch assembly having latch assembly recesses and hooks positioned about the recesses attached to the first scaffold adjacent the second end.
