Quick release coupler for an inflatable towable vehicle
View Patent ↗The present invention provides a quick disconnect coupler for an inflatable towable vehicle including a body member attached to the towing connection of the towable vehicle and a selectively movable arm having a first end pivotally attached to the body member. The arm is movable between a closed position where the second end of the arm engages the body member and secures the towing line, and an open position where the second end pivots out of engagement with the body member and releases the towing line from the body member. A spring biased locking pin is attached to the body member and engages the second end of the arm when in the locked position. The occupant of the towable vehicle selectively pulls a T-handle or strap attached to the spring biased locking pin to pull the locking pin out of engagement with the second end of the arm and release the towing line from the body member.
1. A quick disconnect coupler in combination with an inflatable towable water vehicle having a towing connection and a towing water vehicle having a towing line, the coupler comprising:
a body member attached to the towing connection of the inflatable towable water vehicle;
a selectively movable arm having a first end pivotally attached to the body member and a second end releasably attached to the body member at a point spaced from the first end, the arm being movable between a closed position wherein the second end of the arm engages the body member and secures the towing line to the body member, and an open position wherein the arm pivots out of engagement with the body member and releases the towing line from the body member and
a selectively movable locking pin attached to the body member and being movable between a locked position wherein the pin is disposed to engage and secure the second end of the arm, and a released position wherein the pin is retracted from engagement with the second end of the arm.
2. The coupler of claim 1 wherein the locking pin is biased to the locked position by a spring.
3. The coupler of claim 1 wherein the second end of the arm is disposed to pivot upwardly when the locking pin is moved to the released position.
4. The coupler of claim 3 wherein the second end of the arm is smoothly tapered to allow the unrestricted release of the towing line from the body member when the arm is moved from the closed position to the open position.
5. The coupler of claim 4 wherein the towing connection of the inflatable towable water vehicle is a forwardly extending towing strap having a looped end.
6. The coupler of claim 5 wherein the body member includes a C-shaped portion having opposing ends with openings disposed to receive a threaded pin, and wherein the pin is disposed to extend through the looped end of the towing strap to attach the inflatable towable water vehicle to the body member.
7. The coupler of claim 1 wherein the second end of the arm includes an opening disposed to selectively receive the locking pin when the locking pin is in the locked position.
8. The coupler of claim 7 wherein the locking pin is biased to the locked position by a spring.
