Claim 12

Independent Claim 94 words

A method of supporting for storage a wheeled container chassis having an elongated chassis frame projecting forwardly from rear, ground-engaging chassis wheels, the method comprising: orienting the chassis in a generally vertical attitude with its frame projecting upwardly; inserting the chassis sideways into a storage stall; supporting the rearmost wheels of the chassis on a wheel support means at one side of the stall; and leaning an upwardly-projecting portion of the chassis frame against a chassis frame support at the opposite side of the stall and at a level above the wheel support means.

Claim 13

Independent Claim 94 words

A method of supporting for storage a wheeled container chassis having an elongated chassis frame projecting forwardly from rear, ground-engaging chassis wheels, the method comprising: orienting the chassis in a generally vertical attitude with its frame projecting upwardly; inserting the chassis sideways into a storage stall; supporting the rearmost wheels of the chassis on a wheel support means at one side of the stall; and leaning an upwardly-projecting portion of the chassis frame against a chassis frame support at the opposite side of the stall and at a level above the wheel support means.

Claim 14

Dependent Claim 196 words

A side-loading rack for vertically storing container chassis having a chassis frame and rear wheels, the rack comprising: plural upright frame means spaced laterally apart to define at least two parallel vertical chassis storage slots therebetween along the length of the rack; first chassis support means disposed in a lower portion of each slot for supporting a rear portion of the chassis against one of said frame means on one side of the slot; means defining an entry into each slot along a longitudinal side of the rack, the entry being sized so that the chassis frame, oriented generally vertically, can be moved sideways through the entry into the slot and lowered onto the first chassis support means; and second chassis support means including a cross arm connected to each frame means and extending generally horizontally along an opposite side of each slot at a level above the first chassis support means for supporting an upwardly-projecting portion of the chassis frame in a generally upright position against a second of said frame means; the upright frame means being laterally spaced so that each chassis leans against the second support means at a small angle from vertical.
