摘要:
The manual shopping chair includes a frame supported by a left rear wheel, a right rear wheel, a left front caster wheel and a right front caster wheel. A wheel lock disk with a plurality of radially extending slots is connected to each rear wheel. Springs urge lock bars toward the slots to lock both wheels. The lock bars are manually held out of the slots during movement. A mast is clamped to the frame front. A pair of basket support tubes are pivotally attached to the mast by a shaft in vertical slots. A basket is clamped to basket tubes. The basket is pivotable from a storage position to an upright position. Hooks hold the support tubes in an upright position. The mast top edge is lower than a seat mounted on the frame for nesting multiple shopping units.
