Abstract
A multi-sheet component for a utility vehicle that includes at least one gap between at least two of the sheets, thereby providing a component that enhances worker safety by increasing component stiffness and reducing component thickness. The component is manufactured through multi-sheet thermoforming and uses a conical frustum corrugation to increase stiffness.
Claims20
A method for manufacturing a multi-sheet component including a first sheet that contains a first surface and one or more first corrugations with a first height and a first recessed surface recessed a first depth from the first surface, and a second sheet that contains a second surface and one or more second corrugations with a second height and a second recessed surface recessed a second depth from the second surface, wherein the one or more first corrugations and the one or more second corrugations extend toward each other between the first sheet and the second sheet of the multi-sheet component to form a recessed mounting location that is recessed from the first surface and recessed from the second surface, a conductive hardware mounted through the first recessed surface and the second recessed surface at the recessed mounting location, and wherein the first height prevents the conductive hardware from contacting a conductive object having a dimension greater than the first height, the method comprising:
- thermoforming the first sheet;
- inserting a core material between the first sheet and the second sheet;
- and
- manufacturing the second sheet onto the first sheet and the core material.
A multi-sheet component comprising:
- a first sheet composed of a thermoformable plastic, the first sheet comprising:
- a first surface;
- and
- one or more first corrugations with a first height and a first recessed surface recessed a first depth from the first surface;
- a second sheet composed of a thermoformable plastic, the second sheet comprising:
- a second surface;
- and
- one or more second corrugations with a second height and a second recessed surface recessed a second depth from the second surface,
- wherein the one or more first corrugations and the one or more second corrugations extend toward each other between the first sheet and the second sheet of the multi-sheet component to form a recessed mounting location that is recessed from the first surface and recessed from the second surface;
- and
- a conductive hardware mounted through the first recessed surface and the second recessed surface at the recessed mounting location,
- wherein the first height prevents the conductive hardware from contacting a conductive object having a dimension greater than the first height.
A multi-sheet component comprising:
- a first sheet composed of a thermoformable plastic, the first sheet comprising:
- a first surface;
- and
- one or more first corrugations with a first height and a first recessed surface recessed a first depth from the first surface;
- and a second sheet composed of fiberglass, the second sheet comprising:
- a second surface;
- and
- one or more second corrugations with a second height and a second recessed surface recessed a second depth from the second surface,
- wherein the one or more first corrugations and the one or more second corrugations extend toward each other between the first sheet and the second sheet of the multi-sheet component to form a recessed mounting location that is recessed from the first surface and recessed from the second surface;
- and
- a conductive hardware mounted through the first recessed surface and the second recessed surface at the recessed mounting location,
- wherein the first height prevents the conductive hardware from contacting a conductive object having a dimension greater than the first height width.
