Abstract
A military vehicle includes a cabin. The cabin includes a bottom assembly and a foldable top assembly. The bottom assembly is configured to receive and removably couple with different top assemblies. The foldable top assembly is configured to transition between a folded position for a low velocity aerial drop (LVAD) and a deployed position. The foldable top assembly includes a torsional spring configured to provide a torque to assist transitioning of the foldable top assembly from the folded position to the deployed position.
Claims19
A military vehicle comprising:
- a cabin comprising:
- a bottom assembly configured to receive and removably couple with a plurality of different top assemblies;
- a foldable top assembly configured to transition between a folded position for a low velocity aerial drop (LVAD) and a deployed position, wherein the foldable top assembly comprises a torsional spring configured to provide a torque to assist transitioning of the foldable top assembly from the folded position to the deployed position.
A foldable cabin assembly for a military vehicle, the foldable cabin assembly comprising:
- a bottom frame assembly configured to rest upon and removably couple with a bottom assembly of the military vehicle;
- a roof;
- a plurality of elongated members extending between the bottom frame assembly and the roof, the plurality of elongated members rotatably coupled with the bottom frame assembly and the roof at opposite ends;
- and
- a torsion bar assembly configured to exert a torque on at least one of the plurality of elongated members to facilitate transitioning the foldable cabin assembly from a folded position to a deployed position by rotating the plurality of elongated members in a rotational direction.
A method for delivering and configuring a military vehicle for use, the method comprising:
- performing a low velocity aerial drop (LVAD) of the military vehicle from an airborne aircraft to physically drop the military vehicle to a ground location, the military vehicle comprising a foldable cabin assembly, wherein the foldable cabin assembly is in a folded position when transported in the airborne aircraft and when physically dropped to the ground location;
- driving the foldable cabin assembly into a position partially between the folded position and a deployed position by providing a torque with a torsional spring;
- providing a force that is less than 40 lbf to the foldable cabin assembly to manually drive the foldable cabin assembly into the deployed position, the torsional spring providing assisting torque to reduce the force required to manually dive the foldable cabin assembly into the deployed position, wherein a pin of a first support member of the foldable cabin assembly is configured to be driven into an opening of the foldable cabin assembly to lock the foldable cabin assembly in the deployed position;
- installing a second support member onto the foldable cabin assembly to limit transition of the foldable cabin assembly out of the deployed position and into the folded position;
- and
- installing panels, armored plates, doors, and mirrors onto the foldable cabin assembly.
