Retractable ratcheting tie down

摘要

A retractable ratcheting tie down apparatus is provided, including a frame and a hub rotatably mounted within the frame. A ratchet wheel is mounted to the hub and interfaces with a pawl to selectably prevent motion of the hub relative to the frame. A single tie down strap extends between two attachment members and winds around the hub. An operable means for rotating the hub and ratchet wheel is included to wind the single tie down strap around the hub. Tension between the two attachment members is transmitted directly through the single tie down strap and transitions between segments of the single tie down strap at the windings of the single tie down strap about the hub. In further examples, the operable means for rotating the hub and ratchet wheel is removable. The tie down apparatus can also move freely along the single tie down strap.

1. A retractable ratcheting tie down apparatus including:
a frame; a hub rotatably mounted within the frame; a ratchet wheel mounted to the hub; a pawl, wherein the pawl interfaces with the ratchet wheel to selectably prevent motion of the hub relative to the frame; a single tie down strap extending between two attachment members, the single tie down strap extending through the hub between the two attachment members, the single tie down strap configured to permit winding of the single tie down strap around the hub; an operable means for applying a tension force to the single tie down strap and for rotating the hub and ratchet wheel to wind the single tie down strap around the hub such that tension between the two attachment members is transmitted directly through the single tie down strap and transitions between segments of the single tie down strap at the windings of the single tie down strap about the hub; and a means of urging the hub in order to move the single tie down strap to a fully retracted position.
