Clevis Hitch Storage Support With Automatic Pin Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clevis hitches, particularly those with automatic latching mechanisms, are cumbersome to store due to manual handling and potential safety and dirt issues when laid down on tractors, and existing storage solutions are inadequate.
Innovation Solution
A dedicated storage support structure for clevis hitches that includes a base, guide members, and an actuator to automatically engage the coupling pin, allowing easy sliding and secure locking of the hitch onto the support without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coupling pin is held in the retracted position against a spring bias by a latch mechanism requiring manual release, then the coupling pin can be securely retained, but the operation becomes more complex and requires manual intervention
Solution Approach 1:
The storage support structure automatically triggers the latch mechanism to release the coupling pin when the hitch is placed in the storage position. The hitch itself activates the storage function by its own movement, eliminating the need for manual operation of the latch mechanism during storage.
Solution Approach 2:
The storage support structure is pre-configured with a trigger mechanism that automatically disengages the latch when the hitch reaches the storage position. This preliminary arrangement ensures that the coupling pin is released automatically without requiring manual intervention at the moment of storage.
2Adaptability or versatility
If the clevis hitch is removed from the tractor and laid down in various locations, then it can be stored away from the support rails, but safety issues and dirt contamination occur
Solution Approach 1:
The storage support structure combines the storage function with the hitch mechanism itself, integrating the storage feature into the existing hitch assembly. This merging ensures that the hitch is always stored in a controlled, clean position attached to the tractor, eliminating safety hazards and dirt contamination while maintaining storage flexibility.
3Ease of operation
If the coupling pin is manually lowered using a lever, then the pin can be positioned for engagement, but the operation requires two hands and reduces efficiency
Solution Approach 1:
The storage support structure automatically positions the coupling pin for engagement when the hitch is placed in the storage position. The system performs the positioning action itself without requiring manual manipulation, thereby maintaining operational capability while improving productivity.
4Extent of automation
If an automatic clevis hitch is used with a latch mechanism, then the coupling pin can be automatically lowered when the eye is inserted, but the storage operation becomes more complex
Solution Approach 1:
The storage support structure acts as an intermediary that simplifies the interaction with the automatic latch mechanism. Instead of directly operating the complex latch mechanism, the operator simply places the hitch in the storage position, and the intermediary storage structure automatically triggers the latch release, thereby maintaining automation while reducing operational complexity.

AI summary
A storage support (100) for a clevis hitch (13) has a support structure for receiving the clevis hitch (13) after it has been removed from a towing vehicle. The support structure defines an opening (112) for receiving a coupling pin (22) of the clevis hitch (13) to lock the hitch to the support and one more guide members (for use in positioning the hitch for engagement of the coupling pin (22) in the opening (112). For use with an automatic clevis hitch (13), the storage support has an actuator (114) which enters a jaw (21) of the clevis hitch (13) and disengages a coupling pin latch of the clevis hitch (13), when the clevis hitch (13) is fully received by the support structure. This moves the coupling pin (22) to an engagement position in which it is received by the opening (112) of the storage support.
