A cargo positioning device includes an outer tube having a base fixed to an end thereof, a rack-like inner tube having an end slidably received in the outer tube, a gear rotatably supported by the base and meshed with the rack-like inner tube, a handle having an end pivotally connected to the base,

A cargo positioning device includes an outer tube having a base fixed to an end thereof, a rack-like inner tube having an end slidably received in the outer tube, a gear rotatably supported by the base and meshed with the rack-like inner tube, a handle having an end pivotally connected to the base, and a catch member releasably engaged with a ratchet wheel that is formed on a side of the gear. The handle can be retained in either a first retaining position to prevent from rotation of the gear or a second retaining position to allow rapid outstretching or retraction of the inner tube away from or into the outer tube. The handle is also operable to allow outstretching of the inner tube.

[ What is claimed is:] [1.] A cargo positioning device, comprising:a tube with a base fixed to an end thereof, the base including a first engaging member and a second engaging member provided thereon,a rack means having an end slidably received in the tube and movable in an outstretching direction and a retracting direction,a gear means including a gear rotatably supported by the base and meshed with the rack means, the gear including a ratchet wheel formed on a side thereof to rotate therewith,a handle including a first end pivotally connected to the base and a second operative end, the handle being movable between a first retaining position and a second retaining position,a catch member including an end releasably engaged with the ratchet wheel of the gear means,means for biasing the catch member to engage with the ratchet wheel,a retaining member mounted to the handle,wherein when the handle is at the first retaining position, the retaining member engages with the first engaging member on the base and thus prevents rotational movement of the handle such that the gear is not rotatable while the catch member engages with the ratchet wheel, and when the handle is at the second retaining position, the retaining member engages with the second engaging member on the base, and the first end of the handle causes the catch member to disengage from the ratchet wheel to thereby allowing free rotation of the gear such that the rack means is movable both in the outstretching direction and the retracting direction, and when the handle is reciprocatingly pivoted in a mediate area between the first retaining position and the second retaining position, the retaining member is in a free position, while the catch member engages with the ratchet wheel such that the gear means is rotatable in a direction that allows the rack means to move in the outstretching direction.
