Adjustable Wheel Assembly

An adjustable wheel assembly comprising:

• a bolt movable between a first position and a second position,
• a support bracket comprising a support arm that defines a plurality of apertures, wherein at least one of the plurality of apertures is a point of rotation and at least one of the plurality of apertures is configured to receive the bolt,
• a caster wheel, and
• a swing arm defining a first end, a second end, and a plurality of apertures, wherein the first end receives the bolt in at least one of the apertures and is pivotally coupled to the support arm and the second end is rotatably coupled to the caster wheel, the swing arm being vertically movable between an extended position and an unextended position relative to the support bracket, wherein the caster wheel and swing arm are in the extended position when the bolt is in the first position and the caster wheel and swing arm are in the unextended position when the bolt is in the second position.

A tool storage unit comprising:

• a housing configured to store a tool, the housing having both a first side and a second side opposite the first side, the second side defining an underside;
• and
• an adjustable wheel assembly coupled to the housing, the adjustable wheel assembly comprising:
• a bolt movable between a first position and a second position,
• a support arm, connected to the underside of the second side of the housing, extending outwardly from the housing,
• a caster wheel, and
• a swing arm defining a first end and a second end, wherein the first end is coupled to the support arm and the second end is rotatably coupled to the caster wheel by the bolt, the caster wheel being vertically movable between a raised position and a lowered position relative to the underside of the second side, wherein the caster wheel is in the raised position when the bolt is in the first position and the caster wheel is in the lowered position when the bolt is in the second position.

A method of adjusting the height of a tool storage unit having an adjustable wheel assembly, the method comprising:

• loosening a bolt on the adjustable wheel assembly, wherein the bolt is in a first position and movable between the first position and a second position, and wherein the adjustable wheel assembly is in a raised position when the bolt is in the first position;
• rotating the bolt from the first position to the second position, wherein the adjustable wheel assembly is in a lowered position when the bolt is in the second position;
• and
• tightening the bolt in the second position via a clamp up load.
