A cargo positioning device includes a base including two side walls having aligned first notches and aligned second notches. A pivotal member includes two side walls and a handle for manual operation. The side walls of the pivotal member includes aligned cams, aligned slots, and aligned restrainers.

A cargo positioning device includes a base including two side walls having aligned first notches and aligned second notches. A pivotal member includes two side walls and a handle for manual operation. The side walls of the pivotal member includes aligned cams, aligned slots, and aligned restrainers. A latch plate has two lateral sides slidably guided in the slots of the pivotal member, respectively. Each lateral side has a catch. An engaging section is formed between the lateral sides of the latch plate. A spindle is rotatably extended through the side walls of the base. The spindle is connected with the cams on the pivotal member to rotate therewith. A cargo strap has an end securely attached to the spindle and is releasably wound around the spindle. Two ratchet wheels are mounted on the spindle to rotate therewith. A braking member is pivotally mounted to the base and includes two side walls each having a braking section for releasably engaging with an associated ratchet wheel. When the engaging section of the latch plate is engaged with the first notches, the catches of the latch plate are disengaged from the ratchet wheels and the cams of the pivotal member urge the braking sections of the braking member to a position disengaged from the ratchet wheels, thereby allowing rapid pulling of the cargo strap. When the engaging section of the latch plate is engaged with the second notches, the catches of the latch plate are engaged with the ratchet wheels and the restrainers of the pivotal member urge the braking sections of the braking member to engage with the ratchet wheels, thereby preventing rotation of the spindle. When the engaging section of the latch plate is neither engaged in the first notches nor engaged in the second notches, the catches of the latch plate engage with the ratchet wheels and the braking sections of the braking member are engaged with the ratchet wheels, thereby allowing rotation of the spindle for tightening the cargo strap.
