A strap tensioning buckle apparatus provides a ratchetless strap tensioning buckle apparatus for tensioning straps utilized in tying down objects. The ratchetless strap tensioning buckle apparatus has a base having a first end and a second end, a linkage pivotally attached to the base at a midpoint thereof, a handle having a first end and a second end, the handle having a shaft at the first end thereof for holding a loop of strap, the shaft further rigidly connecting the handle to the linkage, the handle pivoting via the linkage and moving the shaft in an arc from a first position to a second position, wherein moving the shaft from the first position to the second position tightens the strap and locks the strap in place. |

1. A buckle apparatus comprising:
a base having a first end and a second end and a first side and second side, and a first shaft extending from the first side to the second side of the base at a midpoint between the first and second ends of the base, the first end of the base attachable to an end of a strap; first and second linkages extending from the base proximate the midpoint of the base, said first and second linkages having a first horizontal bar extending between and connected to the first and second linkages, the first and second linkages pivotally attached to the base at a first end of each at first and second pivot points, respectively, on the first and second sides of the base, respectively, said first and second linkages further having a second shaft attached to and connecting the first and second linkages at about a midpoint of each of the first and second linkages; and a handle comprising a first leg and a second leg, and a second horizontal bar connecting the first leg to the second leg, wherein the first leg is connected to and moves with the first linkage at the second shaft and the second leg is connected to and moves with the second linkage at the second shaft such that the handle moves from a first position to a second position through a pivotal movement of the first and second linkages, wherein the first leg of the handle has a first slot therein and the second leg of the handle has a second slot therein wherein the first horizontal bar between the first and second linkages is disposed through the first and second legs of the handle through the first and second slots, and further wherein the first and second legs of the handle are pivotally connected to the first and second linkages, respectively, at the second shaft wherein the first horizontal bar between the first and second linkages moves within the first and second slots of the handle, wherein when a loose end of a strap is threaded around the first shaft, looped around the second shaft, and threaded back around the first shaft, and the handle pivots from the first position to the second position, the second shaft moves in an arc over the first shaft from a first position to a second position, locking the strap and preventing movement thereof. |
