Abstract

A vehicle tow recovery eye includes a shaft between a towing end connectable to a towable item and an insertion end that is insertable in a vehicle opening, a resistance assembly mounted on the shaft; and a locking pin having an axis that is substantially perpendicular to an axis of the shaft. The tow recovery eye can be used with a portion of a vehicle frame that includes a frame opening dimensioned to accommodate insertion of the shaft and the locking pin.

First claim

The invention claimed is:

1. A vehicle tow recovery eye, comprising:
a threadless shaft extending along a longitudinal axis from a towing end connectable to a towable item to a locking pin that is insertable in a vehicle opening, the shaft having a substantially circular cross-section and a diameter that is substantially constant along the longitudinal axis; and
a resistance assembly mounted on the shaft;
wherein the locking pin has an axis that is substantially perpendicular to the longitudinal axis of the shaft.

2. The tow recovery eye of claim 1 , wherein the resistance assembly includes a coil spring.

3. The tow recovery eye of claim 2 , wherein the resistance assembly further includes a fixed stop and a moveable stop mounted to the shaft.

4. The tow recovery eye of claim 3 , wherein the coil spring is disposed between the fixed stop and the moveable stop, the fixed stop being closer to the towing end than the moveable stop.

5. The tow recovery eye of claim 4 , wherein the fixed stop and the moveable stop are each a washer.

6. The tow recovery eye of claim 1 , wherein the towing end includes a loop that is connectable to a towable item.

7. A vehicle towing system, comprising:
a vehicle tow recovery eye that includes:
a threadless shaft extending along a longitudinal axis from a towing end connectable to a towable item to a locking pin that is insertable in a vehicle opening, the shaft having a substantially circular cross-section and a diameter that is substantially constant along the longitudinal axis;
a resistance assembly mounted on the shaft,
wherein the locking pin has an axis that is substantially perpendicular to the longitudinal axis of the shaft; and

a portion of a vehicle frame that includes a frame opening dimensioned to accommodate insertion of the shaft and the locking pin.

8. The towing system of claim 7 , wherein the frame opening includes a circular portion dimensioned to accommodate the shaft, and a slot dimensioned to accommodate the locking pin.

9. The towing system of claim 7 , further including a vehicle bumper having a bumper opening that is dimensioned to accommodate insertion of the tow recovery eye.

10. The towing system of claim 9 , further comprising a vehicle that includes the portion of the vehicle frame and the bumper.

11. The towing system of claim 7 , wherein the tow recovery eye is rotatable upon being inserted into the frame opening, and rotation of the tow recovery eye secures the locking pin against a wall of the frame.

12. The towing system of claim 11 , wherein the resistance assembly includes a resistance device that is decompressible when the locking pin is secured against the wall of the frame.

13. The towing system of claim 7 , wherein the resistance assembly includes a resistance device that is compressible when the locking pin contacts the frame and the tow recovery eye is pushed toward the frame.

14. The towing system of claim 7 , wherein the resistance assembly includes a coil spring.

15. The towing system of claim 14 , wherein the resistance assembly further includes a fixed stop and a moveable stop mounted to the shaft.

16. The towing system of claim 15 , wherein the coil spring is disposed between the fixed stop and the moveable stop, the fixed stop being closer to the towing end than the moveable stop.

17. The towing system of claim 15 , wherein the fixed stop and the moveable stop are each a washer.

18. The towing system of claim 7 , wherein the towing end includes a loop that is connectable to a towable item.
