Abstract

A hitch release system for releasing the locked engagement of a hitch, the hitch having a manually operable release bar coupled to a locking mechanism, the hitch release system includes a selectively actuatable power assist system, the power assist system being releasably, operably coupled to the release bar, wherein actuation of the power assist system acts to translate the release bar in a first axial direction, such translation acting to release the locking mechanism. A method of release is further included.

Claims (16)

1. A hitch release system for releasing the locked engagement of a hitch, the hitch having a manually operable release bar coupled to a locking mechanism for mounting on a vehicle, the hitch release system comprising:

a selectively actuatable power assist system, the power assist system being releasably, operably coupled to the release bar for effecting translation thereof in a selected axial direction, the power assist system being spaced apart from the hitch, the power assist system being releasably, operably coupled to the release bar by a coupler, the release bar being free to translate axially with respect to the coupler when the release bar is manually actuated, the coupler being a pivotable arm, the pivotable arm having a forked, cammed engaging portion.

2. The hitch release system of claim 1 , wherein actuation of the power assist system acts to translate the release bar in a first axial direction, such translation acting to release the locking mechanism.

3. The hitch release system of claim 1 , the power assist system being releasably, operably coupled to the release bar by a coupler, the release bar being free to translate axially with respect to the coupler when the release bar is manually actuated.

4. The hitch release system of claim 3 , the power assist system being selectively pneumatically, hydraulically, electrically, or pneumatically/hydraulically actuatable.

5. The hitch release system of claim 1 , the power assist system including a power assist actuator, the actuator being operably coupled to a pivot arm, the pivot arm being operably coupled to the release bar.

6. The hitch release system of claim 1 , the power assist system including a manually actuatable switch being operably coupled to a power assist actuator for selectively actuating the power assist actuator.

7. The hitch release system of claim 1 , including a biasing element, the biasing element acting on the release bar to bias the release bar in a locked disposition.

8. A hitch release system for releasing the locked engagement of a hitch, the hitch having a manually operable release bar coupled to a locking mechanism and being mounted on a vehicle, the hitch release system comprising:

a pneumatically actuatable power assist system, the power assist system being releasably, operably coupled by means of a coupler to the release bar, wherein actuation of the power assist system acts to translate the release bar in a first axial direction by means of a pivotable arm, such translation acting to release the locking mechanism, the coupler being a pivotable arm, the pivotable arm having a forked, cammed engaging portion.

9. The hitch release system of claim 8 , the power assist system being releasably, operably coupled to the release bar by the pivotable arm, the release bar being free to translate axially with respect to the pivotable arm when the release bar is manually actuated.

10. The hitch release system of claim 9 , the power assist system including a power assist actuator, the actuator being operably coupled to the pivot arm, the pivot arm being operably coupled to the release bar.

11. The hitch release system of claim 8 , the power assist system including a manually actuatable switch being operably coupled to a power assist actuator for selectively actuating the power assist actuator.

12. The hitch release system of claim 8 , including a biasing element, the biasing element acting on the release bar to bias the release bar in a locked disposition.

13. A hitch release system for releasing the locked engagement of a hitch, the hitch having a manually operable release bar coupled to a locking mechanism and being mounted on a vehicle, the hitch release system comprising:

a pneumatically actuatable power assist system the power assist system being releasably, operably coupled to the release bar, wherein actuation of the power assist system acts to translate the release bar in a first axial direction, such translation acting to release the locking mechanism, the power assist system being releasably, operably coupled to the release bar by a coupler, the release bar being free to translate axially with respect to the coupler when the release bar is manually actuated, the coupler being a pivotable arm, the pivotable arm having a forked, cammed engaging portion.
