Belt ratcheting system with dual rollers and adjustable release buckle
A ratcheting belt system with opposed rollers and quick release capability provides two opposed rollers which frictionally allow a tightening belt of a safety harness, cargo securement system, between themselves compressively, via a manually operated ratcheting handle such that the excess length of belt distal to the active portion used for securement is passed through the system substantially parallel to the active portion of belt, and need not be contained on a spool. A ratchet mechanism prevents back-out of the belt through the buckle, a manually operated lever provides for opening of the rollers away from each other and easy, quick exit of the driver, passenger, or cargo from securement.
1. A belt ratcheting system comprising:
a buckle;
a bottom roller rotatively mounted to said buckle, said bottom roller being ratcheted for rotation in a first angular direction;
a release handle rotatively mounted to said buckle;
a top roller, rotatively mounted with respect to said release handle, said top roller being ratcheted for rotation in a second angular direction opposite said first angular direction, and said top roller being moved into and out of engagement with said bottom roller by said release handle;
a handle for torqueing said top roller in said second angular direction;
an active belt having an end looped underneath said top and bottom rollers and around said top roller and then between said top and bottom rollers; and
wherein said active belt is pulled toward said buckle when said handle torques said top roller in said second direction and is restrained from release by said bottom and top rollers when said rollers are engaged and wherein said release handle removes said top roller from engagement with said bottom roller to release said belt.
2. A belt ratcheting system as described in claim 1 wherein said top roller rotates along a radius eccentric from a connective axis of said top roller with said release handle.
3. A belt ratcheting system as described in claim 2 wherein said top roller pivots with respect to said release handle along said connective axis with said release handle.
4. A belt ratcheting system as described in claim 1 wherein said top roller has a ratchet wheel with a pawl along an interior of said top roller ratchet wheel to ratchet said top roller in said second direction.
5. A belt ratcheting system as described in claim 4 wherein said pawl to ratchet said top roller is spring biased.
6. A belt ratcheting system as described in claim 4 wherein said handle has a pawl to prevent angular movement of said top roller, and said handle pawl and said top roller ratchet wheel pawl are aligned with one another.
7. A belt ratcheting system as described in claim 1 wherein said handle has a pawl to prevent angular movement of said top roller in a direction opposite said second angular direction.
8. A belt ratcheting system as described in claim 7 wherein said handle pawl is spring biased.
9. A belt ratcheting system as described in claim 1 wherein said bottom roller has a ratchet wheel with a pawl along an interior of said bottom roller ratchet wheel to ratchet said bottom roller.
10. A belt ratcheting system as described in claim 1 wherein said buckle has a side plate with an arcuate slot and a connective axis of said top roller with said release handle is captured within said arcuate slot.
11. A belt ratcheting system as described in claim 1 wherein the release handle and handle for torqueing the top roller rotate in opposite angular directions.
12. A belt ratcheting system comprising:
a buckle;
a bottom roller rotatively mounted to said buckle, said bottom roller being ratcheted for rotation in a first angular direction;
a release handle rotatively mounted to said buckle;
a top roller, rotatively mounted with respect to said release handle, said top roller being ratcheted for rotation in a second angular direction opposite said first angular direction, and said top roller being moved into and out of engagement with said bottom roller by said release handle, and wherein said top roller rotates along a radius eccentric from a connective pivotal axis of said top roller with said release handle, and wherein said top roller has a ratchet wheel with a pawl along an interior of said top roller ratchet wheel to ratchet said top roller in said second direction;
a handle for torqueing said top roller in said second angular direction, said handle having a spring biased pawl to prevent angular movement of said top roller in a direction opposite said first direction;
an active belt having an end looped underneath said top and bottom rollers and around said top roller and then between said top and bottom rollers; and
wherein said active belt is pulled toward said buckle when said handle torques said top roller in said second direction and is restrained from release by said bottom and top rollers when said rollers are engaged and wherein said release handle removes said top roller from engagement with said bottom roller to release said belt.
13. A belt ratcheting system as described in claim 12 wherein said buckle has a side plate with an arcuate slot and a connective axis of said top roller with said release handle is captured within said arcuate slot.
14. A belt ratcheting system as described in claim 12 wherein said handle pawl and said top roller ratchet wheel pawl are aligned with one another.
15. A belt ratcheting system as described in claim 12 wherein the release handle and handle for torqueing the top roller rotate in opposite angular directions.
16. A method of ratcheting a belt, said method comprising:
providing a buckle;
providing a bottom roller rotatively mounted to said buckle, said bottom roller being ratcheted for rotation in a first angular direction;
providing a release handle rotatively mounted to said buckle;
providing a top roller, rotatively mounted with respect to said release handle, said top roller being ratcheted for rotation in a second angular direction opposite said first angular direction, and said top roller being moved into and out of engagement with said bottom roller by said release handle;
providing a handle for torqueing said top roller in said second angular direction;
providing an active belt having an end looped underneath said top and bottom rollers and around said top roller and then between said top and bottom rollers; and
wherein said active belt is pulled toward said buckle when said handle torques said top roller in said second direction and is restrained from release by said bottom and top rollers when said rollers are engaged and wherein said release handle removes said top roller from engagement with said bottom roller to release said belt.
