Appl. No.:

09/881203

Inventors:

John Curtin - Jacksonville FL, US

International Classification:

A44B001/04
A44B011/25

US Classification:

Abstract:

A restraint device is provided for releasably securing a load in place on a support surface by creating a force in a tensioning line, such as a chain. The restraint device is connected between the load and the support surface. The restraint device includes a rotatable line support member mounted on a support frame. The line support member includes toothed ratchet wheels and a chain bed for receiving the chain. The chain bed is provided with a line-engaging surface which engages the chain and prevents motion of the chain relative to the chain bed. A force can be applied to the chain manually to secure the load. A retention member engages the teeth of the ratchet wheels and prevents motion of the wheels in a loosening direction. A release member disengages the retention member from the ratchet wheels and allows the force in the chain to be quickly released.
