Abstract

The disclosure describes a novel approach for restricting the movement of a moveable system. The disclosure describes a novel locking mechanism utilizing a gravity hinge assembly and pocket assembly. The disclosure further describes a novel method for locking a moveable system.

Claims (29)

1. A locking mechanism comprising:

a gravity hinge assembly attached to an intermediate bin, the gravity hinge assembly comprising:

an extender, and

a pivot, the pivot is attached to the extender and allows the extender to rotate between an engaged position and a disengaged position, wherein the pivot and the extender are configured such that a force of gravity rotates the extender into the engaged position via the pivot when the intermediate bin is lifted to an angle of at least 10 degrees from an intermediate bin rest position;

a moveable system, the moveable system is attached to the intermediate bin, wherein the moveable system is an automated tipper system; and

a pocket assembly attached to the moveable system, the pocket assembly is a chamber and is not a hook, thechamber comprising:

a stop plate, and

an opening, the opening is positioned to receive the extender in the engaged position when the moveable system is in a moveable system rest position,

wherein contact between the extender and the pocket assembly prevent the moveable system from extending away from the intermediate bin when the extender is in the engaged position.

2. The locking mechanism of claim 1 , wherein the chamber further comprises: a guide piece, wherein the guide piece extends out from the exterior of the chamber,

wherein the guide piece is shaped to position the extender in front of the opening of the pocket assembly as the moveable system moves toward the moveable system rest position.

3. The locking mechanism of claim 1 , further comprising a hinge stop, the hinge stop is attached the gravity hinge assembly,

wherein the hinge stop positions the extender at an optimum angle to enter the pocket assembly.

4. The locking mechanism of claim 1 , further comprising a stop bar, the stop bar is attached to the gravity hinge assembly,

wherein the stop bar limits the rotation of the extender on the pivot.

5. The locking mechanism of claim 1 , further comprising a shim, the shim is attached to the pivot, wherein the shim is positioned to increase an amount of the force required to rotate to the extender.

6. The locking mechanism of claim 1 , further comprising a counterweight, the counterweight is attached to the extender, wherein the counterweight is positioned to increase an amount of the force required to rotate the extender.

7. The locking mechanism of claim 1 , wherein the stop plate has a rounded edge, the rounded edge is an exterior edge of the pocket assembly adjacent to the opening and positioned closest to ground when the moveable system is in the moveable system rest position.

8. The locking mechanism of claim 1 , further comprising a pivot lock system, wherein aligning pin thread holes are located on the pivot and the extender.

9. The locking mechanism of claim 1 , wherein the automated tipper system is a robotic arm.

10. A locking mechanism comprising:

a gravity hinge assembly attached to an intermediate bin, the gravity hinge assembly comprising:

an extender, and

a pivot, the pivot is attached to the extender and allows the extender to rotate between an engaged position and a disengaged position;

a moveable system, the moveable system is attached to a supporting device, wherein the moveable system is an automated tipper system;

a pocket assembly attached to the moveable system, the pocket assembly comprising

a stop plate, and

an opening, the opening is positioned to receive the extender in the engaged position when the moveable system is in a moveable system rest position,

wherein contact between the extender and the pocket assembly prevent the moveable system from extending away from the intermediate bin when the extender is in the engaged position.
