Trash can assembly

What is this patent about?

’470 is related to the field of household waste management systems, specifically focusing on the mechanical architecture of trash can lids and their attachment points. The invention addresses the common problems of bulky, unsightly hinge mechanisms that prevent containers from sitting flush against walls, as well as the difficulty of replacing damaged lids without discarding the entire assembly.

The underlying idea behind ’470 is to move the pivot axis and the actuation hardware of the lid into the interior volume of the shell, while utilizing a modular, user-serviceable hinge pin. By shifting the mechanical connection point inward, the design achieves a low-profile silhouette that eliminates the protruding rear hinges found on traditional step cans, allowing for more efficient space utilization and packaging.

The claims of ’470 focus on a hinge assembly that facilitates the easy removal and replacement of the lid through a specific interlocking structure. This is achieved by aligning a mounting bracket on the lid with a housing on the shell, both of which are secured by a removable pivot bar that passes through a central bore and is held in place by a dedicated locking mechanism.

In practice, the invention works by nesting the lid's mounting bracket into a slot in the shell's housing, creating a continuous channel for the pivot bar. A locking bolt or similar fastener engages a groove on the pivot bar to prevent it from sliding out during normal operation. This configuration ensures that the lid remains securely attached during the high-torque movements of a foot-pedal system while remaining accessible for maintenance.

This approach differs from prior solutions by providing a bi-directional removal path for the hinge pin; once the locking mechanism is disengaged, the pivot bar can be pushed out from either side using a simple tool. By integrating the pivot axis within the shell's periphery and utilizing this serviceable pin, the invention provides a durable, high-end aesthetic that does not sacrifice the ability to repair or swap components.
