Abstract

A waste container having a body and a lid pivotably connected to the body. The lid includes a gravity activated locking mechanism having a latch that engages the lid to the body when the container is in an upright position. The locking mechanism rotates to disengage the latch and allow the lid to open when the container is inverted for dumping the waste. The waste container further including a slideable member that is engageable with a locking member when the container is not in an upright position or inverted for dumping, to prevent rotation of the locking mechanism and opening of the lid.

First claim

We claim:

1. A waste container comprising:
a container body having an open top portion and a catch on a front portion of the top portion;
a lid pivotably connected to the top portion of the container body;
a locking mechanism connected to the lid, the locking mechanism including a rotatable member having an axis of rotation; a latch configured to engage the catch when the lid is pivoted to a closed position, a first weight and a lever connecting the rotatable member, wherein placement of the container in an upside down position causes the first weight to rotate the lever about the axis of rotation to disengage the latch from the catch to enable opening of the lid; and,
a moveable member comprising a moveable second weight having a central opening over a post, the moveable member connected to one of the lever and the lid, and a locking member connected to the other of the lever and the lid that is engageable with the moveable member to prevent rotation of the rotatable member, wherein the moveable member moves to a locking position when the container is not in one of an upright position and an upside down position.

2. The waste container of claim 1 wherein the first weight is secured to the locking mechanism by a push-in fastener.

3. The waste container of claim 1 further comprising a button in a front portion of the lid configured to disengage the latch from the catch when the container is in an upright position to enable opening of the lid.

4. The waste container of claim 1 further including a cover plate separating the locking mechanism from an interior of the container body.

5. The waste container of claim 1 wherein the moveable second weight has a circular outer perimeter shape.

6. The waste container of claim 1 wherein the rotatable member is at a first end of the lever.

7. The waste container of claim 6 wherein the latch extends from the first end of the lever.

8. The waste container of claim 7 wherein the first weight is at a second end of the lever.

9. A waste container comprising:
a container body having a bottom and a sidewall extending upward from the bottom to a top opening, the container body including an inwardly directed protrusion proximate the top opening;
a lid pivotably connected at a first end to a first side of the top opening of the container body;
a lock including a rotatable member connected to an interior portion of the lid proximate a second end of the lid opposed from the first end, a first arm extending from the rotatable member, the first arm having a latch element for engaging the protrusion on the container body when the waste container is in an upright position and preventing the lid from opening, and a second arm extending from the rotatable member; and,
a moveable member connected to the second arm and a locking member connected to the lid that is engageable with the moveable member to prevent rotation of the rotatable member, wherein the moveable member has a central opening allowing for slideable movement about a post and moves to a locking position when the container is not in one of an upright position and an upside down position.

10. The waste container of claim 9 further comprising a cover plate connected to an interior portion of the lid, the cover plate separating the second arm from the interior of the container body when the lid is in a closed position.

11. The waste container of claim 9 wherein the first arm extends generally vertically downward when the lid is in a closed position over the opening and the waste container is in an upright position.

12. The waste container of claim 11 wherein the second arm extends generally horizontally when the lid is in a closed position over the opening and the waste container is in an upright position.

13. The waste container of claim 12 wherein the first arm and second arm are at a right angle.

14. The waste container of claim 12 wherein the second arm includes a first end connected to the rotatable member and a second end distal from the rotatable member, the second arm including a first weight proximate the second end.

15. The waste container of claim 14 wherein the first weight is connected to the second arm by a push-in fastener.

16. The waste container of claim 14 wherein the first weight is molded into the second arm.

17. A waste container with a gravity latch comprising:
a container body having a bottom wall, a side wall extending upward from the bottom wall, and an open top;
a lid pivotably connected to the open top;
a gravity locking mechanism having a latch arm, a rotatable hinge portion, a latch connected to a first end of the latch arm and a first weight connected to the latch arm, the latch engageable with the container body when the container is in an upright position and disengageable with the container body when the container is in an upside down position by rotation of the latch arm due to gravity;
a moveable member connected to one of the lid and the latch arm and a locking member on the other of the lid and the latch arm, wherein the moveable member engages the locking member when the container is not one of upright or upside down to prevent rotation of the locking mechanism, wherein the moveable member is a second weight having a central opening allowing for slideable movement about a post and the locking member is a ledge positioned to engage the weight.

18. The waste container of claim 17 wherein the second weight having a generally circular outer perimeter.

19. The waste container of claim 17 wherein the second weight is positioned on the latch arm and the locking member is a ledge connected to the lid.

20. The waste container of claim 17 further comprising a spring connected to the rotatable hinge portion, the latch arm and the latch, wherein application of a force on the latch sufficient to overcome the spring enables rotational movement of the latch with respect to the latch arm.
