Ratchet configurations
View Patent ↗An apparatus and system for improving rope, strap, tie downs, hooks, and nets is provided. Includes a new design whereby the apparatus has a thick walled body made of nylon, aluminum, or stainless steel with a spool and center hub and axle throughout the spool body frame and handle. The apparatus uses multiple coils to automatically retract strap or rope within the spool hub. It also contains a tangential rib opposing the face wheel. The apparatus may have gears on the radius of the wheel, spring loaded slidable pawl plates, or pivotally rotatable pawls or plates which allow the proper engagement of the wheel ratchet. It may also have rope, strap, or belt that is non-cuttable and corrosion, petrol, and chemical resistant used in tie downs and nets. The apparatus may have a lockable body frame, and/or hooks that are lockable to prevent theft.
1. An auto-retracting ratchet assembly comprising:
(a) an axle comprising an axis; and a ratchet wheel comprising gear teeth, said ratchet wheel mounted around said axis;
(b) a frame body rotatably supporting said axle, said frame body comprising a right side and a left side;
(c) a handle comprising a right side and a left side, said handle mounted around said axle, and said handle further comprising at least one detent for engaging with said gear teeth of said ratchet wheel;
(d) a coil spring comprising a width, said coil spring along an exterior wall of at least one of said handle right and left sides, said coil spring coupled to said axle and adapted to force axle to rotate;
(e) said at least one of said handle right and left sides comprising a rim extending at least as deep as said coil spring width so as to form a cavity, said coil spring resting within said cavity; and
(f) a cover provided along said at least one of said handle right and left sides adapted to cover said coil spring and provide housing for said coil spring.
2. The auto-retracting ratchet assembly of claim 1 further wherein said detent is rotatably mounted on said handle, said detent biased to engage with said gear teeth via a detent spring, said detent adapted for press-release to rotate said detent away from said gear teeth so as to allow ratcheting.
3. The auto-retracting ratchet assembly of claim 2 wherein said detent comprises a bent trigger end comprising a rounded edge.
4. The auto-retracting ratchet assembly of claim 1 wherein said handle further comprises a cam built into a handle wall.
5. The auto-retracting ratchet assembly of claim 4 wherein said cam comprises at least one edge to support said handle actuation.
6. The auto-retracting ratchet assembly of claim 1 further comprising a centrifugal clutch adapted to arrest retraction of a strap when said retraction occurs beyond an acceptable predetermined speed.
7. The auto-retracting ratchet assembly of claim 1 wherein said coil spring is centered on said axis and connected to said handle.
8. The auto-retracting ratchet assembly of claim 7 wherein said coil spring is not directly connected with said frame body.
9. The auto-retracting ratchet assembly of claim 1 wherein the other of said at least one of said handle right and left sides comprises a coil spring.
10. The auto-retracting ratchet assembly of claim 1 wherein said right side of said handle and said left side of said handle are joined via bolt.
11. The auto-retracting ratchet assembly of claim 1 further comprising a central lock adapted for actuation to lock wheel in place via an external tool.
