Abstract

Provided is a ratchet tie down including a main body portion, a reel assembly rotatable relative to the main body portion, a first sprocket surrounding the reel assembly, a second sprocket surrounding the reel assembly, at least one first noise reduction disk, at least one second noise reduction disk, and a release pawl biased in a locked position to land on the noise reduction disks to dampen the sound as the release pawl engages teeth of the sprockets.

First claim

What is claimed is:

1. A ratchet tie down comprising:
a main body portion having a base and first and second sides extending from the base;
a reel assembly rotatable relative to the main body portion;
a handle assembly rotatable relative to the main body portion, the handle assembly including first and second rail arms spaced from one another and a handle attached to the first and second rail arms;
a first sprocket through which the reel assembly extends, the first sprocket disposed between the first side of the main body portion and the first rail arm and including a plurality of teeth;
a second sprocket through which the reel assembly extends, the second sprocket disposed between the second side of the main body portion and the second rail arm and including a plurality of teeth;
at least one first noise reduction disk through which the reel assembly extends, the at least one first noise reduction disk being adjacent to the first sprocket;
at least one second noise reduction disk through which the reel assembly extends, the at least one second noise reduction disk being adjacent to the second sprocket; and
a release pawl movable from a locked position to an unlocked position, the release pawl being biased in the locked position to land on the noise reduction disks and engage the teeth of the first and second sprockets.

2. The ratchet tie down according to claim 1 , wherein the at least one first and second noise reduction disks each have an outer diameter greater than a diameter of the first and second sprockets at roots of the teeth of the sprockets.

3. The ratchet tie down according to claim 1 , wherein the first and second rail arms each include an overmolded bumper covering at least a portion of a periphery of the rail arms.

4. The ratchet tie down according to claim 1 , wherein the release pawl includes a body having arms each with a front side for engaging a respective one of the first and second sprockets and a backside having a projection that extends into a respective biasing member that biases the release pawl in the locked position.

5. The ratchet tie down according to claim 1 , wherein the handle assembly includes a handle with a knurled surface and flanged portions on either end that are received in openings in the first and second rail arms.

6. The ratchet tie down according to claim 5 , wherein the handle assembly further includes a pair of handle lock caps each having a plurality of circumferentially spaced protrusions that are received in openings in the flanged portions to secure the handle to the rail arms.

7. The ratchet tie down according to claim 1 , wherein the first and second rail arms each include a slot extending therethrough for receiving respective arms of the release pawl, wherein each slot includes a first portion that receives the respective arm, and a second portion that receives the respective arm and a respective biasing member.

8. The ratchet tie down according to claim 7 , wherein the first and second rail arms each include a projection extending into the respective second portion that extends partially through the respective biasing member.

9. A ratchet tie down comprising:
a main body portion;
a reel assembly rotatable relative to the main body portion;
a handle assembly having first and second rail arms rotatable relative to the main body portion;
a first sprocket surrounding the reel assembly between the main body portion and the first rail arm;
a second sprocket surrounding the reel assembly between the main body portion and the second rail arm;
at least one first noise reduction disk abutting the first sprocket;
at least one second noise reduction disk abutting the second sprocket; and
a release pawl biased in a locked position to land on the noise reduction disks and engage teeth of the sprockets.

10. The ratchet tie down according to claim 9 , wherein the at least one first and second noise reduction disks each have an outer diameter greater than a diameter of the first and second sprockets at roots of the teeth of the sprockets.

11. The ratchet tie down according to claim 9 , wherein the at least one first noise reduction disk includes a pair of first noise reduction disks adjacent both sides of the first sprocket and the at least one second noise reduction disk includes a pair of second noise reduction disks adjacent both sides of the second sprocket.

12. The ratchet tie down according to claim 9 , wherein the first and second rail arms each include an overmolded bumper covering at least a portion of a periphery of the rail arms.

13. A ratchet tie down comprising:
a main body portion having a base and first and second sides extending from the base;
a handle assembly rotatable relative to the main body portion, the handle assembly including first and second rail arms each including an overmolded bumper covering at least a fifty percent of a periphery of the respective rail arm;
a reel assembly rotatable relative to the main body portion and extending through each of the first and second rail arms;
a first sprocket through which the reel assembly extends, the first sprocket disposed between the first side of the main body portion and the first rail arm and including a plurality of teeth;
a second sprocket through which the reel assembly extends, the second sprocket disposed between the second side of the main body portion and the second rail arm and including a plurality of teeth; and
a release pawl movable from a locked position to an unlocked position.

14. The ratchet tie down according to claim 13 , further including at least one first noise reduction disk adjacent the first sprocket and at least one second noise reduction disk adjacent the second sprocket.

15. The ratchet tie down according to claim 13 , wherein the handle assembly includes a handle with a knurled surface and flanged portions on either end that are received in openings in the first and second rail arms.

16. The ratchet tie down according to claim 15 , wherein the handle assembly further includes a pair of handle lock caps each having a plurality of circumferentially spaced protrusions that are received in openings in the flanged portions to secure the handle to the rail arms.

17. The ratchet tie down according to claim 13 , wherein the release pawl includes a body having arms each with a front side for engaging a respective one of the first and second sprockets and a backside having a projection that extends into a respective biasing member that biases the release pawl in the locked position.

18. The ratchet tie down according to claim 13 , wherein the first and second rail arms each include a slot extending therethrough for receiving respective arms of the release pawl, wherein each slot includes a first portion that receives the respective arm, and a second portion that receives the respective arm and a respective biasing member.

19. The ratchet tie down according to claim 18 , wherein the first and second rail arms each include a projection extending into the respective second portion that extends partially through the respective biasing member.

20. A ratchet tie down comprising:
a main body portion having a base and first and second sides extending from the base;
a reel assembly rotatable relative to the main body portion;
first and second springs;
a handle assembly rotatable relative to the main body portion, the handle assembly including a first rail arm having a first slot and a first spring seat for receiving a first end of the first spring and a second rail arm having
