The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

A tool storage device system includes a base and a tool storage container removably coupled to the base. The tool storage container slides in a first direction relative to the base to attach the tool storage container to the base, and the tool storage container slides in a second direction, opposite the first direction, relative to the base to remove the tool storage container from the base.

Disclosed is a modular jewelry storage container having a main container having a lid at a first end and a connector on a second end. The main container includes interior dividers defining interior spaces within an interior space of the main container. The lid is removably attached to the main container. The modular jewelry storage container includes a module removably attached to the main container via the connector at the second end, and has an internal storage space separate from the interior spaces of the main container and at least one storage element within the internal storage space.

A rifle carrying case system. The rifle carrying case system includes a utility case for carrying rifles, a roller case for carrying rifle gear and accessories, and a docking station for mounting the utility case to a support structure such as a wall. The utility case and the roller bag case each include corresponding attachment mechanisms that enables the utility case to be removably coupled to the roller case for easy transit of the cases as a combined single unit. The attachment mechanisms include upper and lower hook members configured with the roller bag (e.g., with its extendable handle) and corresponding slots on the utility case that may be engaged by the hooks.

Various embodiments of a rolling modular storage unit and various features and devices for modular storage units are provided. In various embodiments the rolling modular storage unit includes a main body with a front surface, a rear surface, and side surfaces extending between and connecting the front surface and the rear surface. In specific embodiments, the main body includes one or more handles attached to the front and/or side surfaces. In one or more embodiments, a handle is positioned along the rear surface. In such an embodiment, the handle includes a metal portion that allows for magnetic mounting of one or more accessories.
