Portable fan

A portable fan comprising:

• a main body;
• a fan head coupled to the main body, the fan head including a fan configured to be selectively powered by a power source;
• and
• a first arm rotatably coupled to the main body relative to the fan head, the first arm including
• a first projection extending outwardly from the main body, and
• a second projection spaced apart from the first projection and extending outwardly from the main body generally parallel to the first projection, the first projection and the second projection defining a gap therebetween, the gap configured to receive a support structure to support the portable fan on the support structure.

A portable fan comprising:

• a main body including a first end and a second end opposite the first end;
• a fan head coupled to the main body between the first end and the second end, the fan head including a fan configured to be selectively powered by a power source;
• a first arm rotatably coupled to the main body relative to the fan head, the first arm including a first distal end opposite from the main body;
• and
• a second arm rotatably coupled to the main body relative to the fan head and the first arm, the second arm including a second distal end opposite the main body, the second arm being rotatable relative to the first arm between a first arm position, in which the second distal end is coupled to the first distal end such that the first arm and the second arm cooperate to form a closed loop, and a second arm position, in which the second distal end is spaced apart from the first distal end,
• wherein the fan head is rotatable relative to the first arm and the second arm between a first fan head position, in which a portion of the fan is received in the closed loop, and a second fan head position, in which the fan head is spaced apart from the closed loop.
