Abstract
A pneumatic operated hinge and latch system for agriculture seed box lids preventing loss of the lid during adverse weather conditions, wherein the system provides a more reliable and secure locked engagement and an easy transition to an unlocked engagement.
Claims9
A device, comprising:
- a bracket extending from a bracket proximal end to a bracket distal end;
- an arm extending from an arm proximal end to an arm distal end;
- a first pivotal connection joining the bracket distal end and the arm distal end;
- a latch extending from a latch distal end to a latch proximal end;
- a second pivotal connection joining the latch to the arm so that the latch moves between an unlocked engagement and a locked engagement;
- a spring mechanism biasing the latch in the locked engagement;
- an attachment point disposed along the latch between the second pivot connection and the latch distal end;
- and
- a pneumatic actuator interconnecting the bracket proximal end and the attachment point for moving the arm between a closed engagement and an open engagement, wherein the open engagement precludes the locked engagement.

- a bracket extending from a bracket proximal end to a bracket distal end;
- an arm extending from an arm proximal end to an arm distal end;
- a first pivotal connection joining the bracket distal end and the arm distal end;
- a latch extending from a latch distal end to a latch proximal end;
- a second pivotal connection joining the latch to the arm so that the latch moves between an unlocked engagement and a locked engagement;
- a spring mechanism biasing the latch in the locked engagement;
- an attachment point disposed along the latch between the second pivot connection and the latch distal end;
- a pneumatic actuator interconnecting the bracket proximal end and the attachment point for selectively moving the arm between a closed engagement and a range of open engagements, wherein any open engagement precludes the locked engagement, wherein the pneumatic actuator includes at least one piston, wherein the closed engagement releases pneumatic pressure within the at least piston;
- a container sleeve for slidably receiving the bracket proximal end;
- a locking member pivotally attached to the bracket proximal end so that the locking member moves from an unlocked condition to a locked condition, preventing the bracket proximal end from sliding out of the container sleeve;
- and
- two spaced apart wind flanges transversely joined to the upper arm so that the latch nests between the two spaced apart wind flanges in the locked engagement.
