Abstract: Described herein are various coupling systems to be used with storage units that are selectively coupled and decoupled. The coupling systems may be used with storage units that are stackable and/or transportable, thus allowing the storage units to function well within a large stationary environment, such as a basement, and also for a subset of the storage units to be selected and easily moved to another location.

Abstract: A utility knife including a handle, a blade, a first blade holder, and a spare blade holder. The spare blade holder is pivotal with respect to the handle between an open position where the recess is exposed to allow a spare blade to be removed from the spare blade holder and a closed position where the recess is within a slot of the handle to inhibit removal of the spare blade from the spare blade holder. The spare blade holder further including a cam surface and the cam surface of the spare blade holder engages a cam surface of the handle when the spare blade holder is in the closed position to urge the spare blade holder in a direction from a first longitudinal side of the handle toward a second longitudinal side of the handle to allow the first blade holder to pivot between extended and folded positions.

Abstract: Components of support platforms and coupling mechanisms within a modular system are provided. The support platforms include female couplers with ribs that couple with male couplers of utility modules. The female couplers of the support platforms and the male couplers of the utility modules are configured to facilitate coupling the utility modules to the support platforms.

Abstract: A storage container with various aspects is described herein. The storage container may have cleats or cleat receptacles to interact with other storage containers and/or accessories. The storage container may also include rails for attachment of various accessories. Some versions of the storage container may further include telescopic uprights connected to a handle. Many of the versions of the storage containers may further include wheels for transporting the storage containers and their contents.

Abstract: A hard hat attachment system is described with front, back, and side mounts to support various accessories. Mounts of hard hat receive slots of a bracket that fit around the ridges. Auxiliary ridges receive clips within ports. The user customizes the hard hat for the particular task with the preferred accessories used to complete the job. For example, lamps, face-shields, reflectors, tool carriers, and eyeglass holders are interchangeably releasably coupled to mounting and/or auxiliary ridges on the hard hat. In this way, the hard hat is customized and/or modified to support a wide variety of accessories that are securely and releasably attached to mounting and/or auxiliary ridges without destructive alterations to the hard hat. Brackets couple to mounts and clips couple to ports to secure and/or lock various accessories in place during operation and prevent accidental knocks or jarring the accessory loose.

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