Abstract

A towing hitch for coupling a towing vehicle with a vehicle which is to be towed is provided which includes a body having a pocket within which a receiver tube is pivotally mounted. The receiver tube telescopically mounts a tow bar which is configured for selected operative securement to a vehicle which is to be towed. The hitch is selectively locked in position using first and second pin assemblies, the first pin assembly including a first pin biased toward engagement with the body so as to selectively lock the receiver tube in place, and the second pin assembly including a second pin biased toward engagement with the tow bar so as to selectively lock the tow bar in place.

Claims

1. A hitch for use in coupling a towing vehicle with a vehicle which is to be towed, the hitch comprising:

a hitch body suited for operative securement to the towing vehicle, said body defining a pocket with an elongate opening which provides access thereto;

an elongate receiver tube having forward and rearward ends, said forward end being operatively pivotally connected to said body from within said pocket and said rearward end extending from within said pocket through said opening;

an elongate tow bar mounted for movement within said receiver tube, said tow bar being configured for selected operative securement to the vehicle which is to be towed;

a first pin assembly mounted on said receiver tube, said first assembly including a first movable pin which is biased toward engagement with said body so as to lock said receiver tube in place without restricting movement of said tow bar upon pivoting of said receiver tube into a predefined tube orientation; and

a second pin assembly mounted on said receiver tube, said second assembly including a second movable pin which is biased toward engagement with said tow bar so as to lock said tow bar in place without restricting pivot of said receiver tube upon movement of said tow bar into a predefined bar orientation.

2. The hitch of claim 1, wherein said body defines a body recess positioned to accommodate receipt of said first pin when said tube is in said predefined tube orientation.

3. The hitch of claim 2, wherein said tow bar defines a tow bar recess positioned to accommodate receipt of said second pin when said tow bar is in said predefined bar orientation.

4. The hitch of claim 1, wherein said body includes an elongate glide surface with a body recess defined therein, said first pin being biased toward engagement with the body'"'"'s glide surface for selected travel therealong, said body recess being configured for capture of said first pin upon passage of said first pin thereover.

5. The hitch of claim 4, wherein said tow bar includes a elongate glide surface with a tow bar recess defined therein, said second pin being biased toward engagement with the tow bar'"'"'s glide surface for selected travel therealong, said tow bar recess being configured for capture of said second pin upon passage of said second pin thereover.

6. The hitch of claim 1, wherein said first pin is biased toward engagement with said body via a spring.

7. The hitch of claim 6, wherein said second pin is biased toward engagement with said tow bar via a spring.

8. The hitch of claim 1 further comprising a keeper mounted on said receiver tube, said keeper selectively operating on said tow bar to limit movement thereof.

9. The hitch of claim 8, wherein said tow bar defines an elongate slot, said keeper being set within said slot to limit movement of said tow bar.

10. The hitch of claim 9, wherein said tow bar is movable between a fully-retracted position wherein said keeper engages a first terminal end of said slot and a fully-extended position wherein said keeper engages a second terminal end of said slot.

11. A hitch for use in coupling a towing vehicle with a vehicle which is to be towed, the hitch comprising:

a hitch body suited for operative securement to the towing vehicle, said body having a pocket with an elongate opening and an elongate glide surface with a body recess defined therein;

an elongate receiver tube having forward and rearward ends, said forward end being operatively pivotally connected to said body from within said pocket and said rearward end extending from within said pocket through said opening;

an elongate tow bar mounted for movement within said receiver tube, said tow bar being configured for selected operative securement to the vehicle which is to be towed and defining a tow bar recess therein;

a first pin assembly mounted on said receiver tube, said first assembly including a first pin biased for movement along said receiver tube toward engagement with said glide surface, said first pin being effective to lock said receiver tube in place without restricting movement of said tow bar upon pivoting of said receiver tube to an orientation wherein said first pin is aligned with said body recess; and

a second pin assembly mounted on said receiver tube, said second assembly including a second pin which is biased for movement toward engagement with said tow bar, said second pin being effective to lock said tow bar in place upon movement of said tow bar to an orientation wherein said second pin is aligned with said tow bar recess.
