Abstract
The present invention is directed to a portable fan for the use in firefighting and other ventilation use-cases. The portable fan provides firefighters the ability to provide positive pressure ventilation in use for fighting fires which does not require power cables or combustible fuel powered motors, and provides increased portability, reduced risk, and reduced deployment time associated with managing and fighting a fire.
Claims20
A portable fan comprising:
- a frame comprising a first frame portion and a second frame portion;
- a hinge interconnecting the first frame portion and the second frame portion, the hinge having a first axis of rotation;
- a wheel assembly rotatably interconnected to the first frame portion about a second axis of rotation, the wheel assembly configured to engage the ground, and the second axis of rotation substantially parallel to the first axis of rotation;
- a fan assembly comprising a motor, the fan assembly rotatably interconnected to the first frame portion about a third axis of rotation, the third axis of rotation substantially orthogonal to the first axis and second axis of rotation;
- the fan assembly having a range of adjustability about the third axis of rotation;
- and a fourth axis parallel to the first axis;
- wherein in a first configuration, the first frame portion and the second frame portion are configured to form a substantially contiguous border around the fan assembly that is radially offset from the fourth axis,
- wherein in a second configuration, the second frame portion is configured to extend away from the hinge in an upward direction, and
- wherein the range of adjustability of the fan in the first configuration is equal to the range of adjustability of the fan in the second configuration.

A portable fan comprising:
- a frame comprising a first frame portion and a second frame portion;
- a frame release;
- a hinge interconnecting the first frame portion and the second frame portion, the hinge having a first axis of rotation;
- a hinge lock;
- a wheel assembly having two wheels, the wheels rotatably interconnected to the first frame portion about a second axis of rotation, the wheel assembly configured to engage the ground, and the second axis of rotation substantially parallel to the first axis of rotation;
- a plurality of feet disposed on a bottom aspect of the portable fan;
- a fan assembly comprising a motor, the fan assembly rotatably interconnected to the first frame portion about a third axis of rotation, the third axis of rotation substantially orthogonal to the first axis and second axis of rotation;
- the fan assembly having a range of adjustability of at least about 180 degrees about the third axis of rotation;
- and
- a fourth axis parallel to the first axis;
- wherein at least one of the hinge lock and the frame release must be actuated in order to transition the portable fan from a first configuration to a second configuration;
- wherein in the first configuration, the first frame portion and the second frame portion are configured to form a substantially contiguous border around the fan assembly that is radially offset from the fourth axis,
- wherein in the second configuration, the second frame portion is configured to extend away from the hinge in an upward direction,
- wherein the range of adjustability of the fan in the first configuration is equal to the range of adjustability of the fan in the second configuration, and
- wherein wheels engage with the ground when the portable fan is rotated toward the wheel assembly.
