Biased slide lock
View Patent ↗A biased sliding lock for use with containers provides a locking mechanism to lock the lid relative to a pail. The bias can be overcome to place the container in an unlocked configuration allowing the lid to be rotated relative to the pail. The locking mechanism preferably includes a slide with a leg which may cooperate with a leg of the pail to prevent rotation of the lid relative to the pail in the locked configuration. The legs may have angled surfaces to facilitate closing directly into the locked configuration for at least some embodiments.
1. A pail comprising:
a container hingedly connected to a lid at a pivot;
a sliding lock assembly, said lock assembly having a slide at least operably coupled to the lid and constrained to slide along a rail of the lid;
said slide having a first foot, and a second foot connected to the container;
whereby when in both a closed configuration and a locked configuration, the first foot and second foot overlap to prevent pivoting of the lid relative to the container to an open configuration from the closed configuration, and when in an unlocked configuration, the first and second feet do not elevationally overlap permitting the lid to be pivoted to the open configuration relative to the container from the closed configuration.
2. The pail of claim 1 further comprising a spring member, said spring member biasing the slide to the locked configuration.
3. The pail of claim 2 wherein the spring member is connected to the lid.
4. The pail of claim 1 further comprising a slot formed in the pail to receive at least a portion of the slide in the locked configuration.
5. The pail of claim 4 wherein the slide moves linearly relative to the slot and rail between the locked and unlocked configurations.
6. The pail of claim 4 wherein a front of the slide is restrained from outward movement by an upwardly extending leg assisting in forming the slot.
7. The pail of claim 1 wherein the slide overlappingly connects to the rail.
8. The pail of claim 1 wherein with the slide directed to a locked and open configuration, one of the first and second foot has at least one of a curved and an angled surface directed toward the other of the first and second foot whereby upon downward movement of the lid relative toward the container toward the closed configuration the one of the first and second feet deflects until in a closed and locked configuration.
9. The pail of claim 8 wherein the one of the first and second feet deflects outwardly away from the pail when contacting the other of the first and second feet.
10. The pail of claim 8 wherein the one of the first and second feet deflects inwardly toward the pail when contacting an other of the first and second feet.
11. The pail of claim 10 wherein the other of the first and second feet deflects outwardly away from the pail.
12. The pail of claim 11 wherein both the first and second feet have at least one curved and angled surfaces directed toward the other foot.
