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: Various carrying mechanisms to transport a storage device, container or unit are shown. The carrying mechanisms actuate between various positions that may interfere with opening a lid of the storage unit. Various configurations of the carrying mechanisms reduce their profile when in use. Also described are multi-segmented carrying mechanisms that provides a beneficial weight distribution while facilitating actuating the carrying mechanism between different positions.

Abstract: A ladder is provided. The ladder includes coupling components that couple modular storage elements to the ladder. The ladder includes various components to facilitate moving, carrying, and placing the ladder.

Abstract: A ratcheting tool is provided. The ratcheting tool includes a ratchet mechanism including a gear structure and a pawl structure. The pawl structure includes at least one elastic or integral component that provides spring action/biasing to the pawl teeth which facilitates ratcheting movement.

Abstract: A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

Abstract: A tool attachment system is provided. The tool attachment system includes a tool attachment device and a receiver that cooperate to lock or secure, for example, a bag or pouch. When the tool attachment device is coupled to the receiver, a locking mechanism locks the tool attachment device to the receiver in a locked position. To remove the tool attachment device, a user applies a force to a button to cause the tool attachment device to disengage from the receiver.

Abstract: Various embodiments of pliers and pipe wrenches are provided. Wire cutters enable a finger pivot hole to enhance the grasp of the wire cutters while rotating the tool and/or stripping wire. Pipe wrenches include different configurations of teeth to improve durability and grip on a workpiece. Pliers are provided with axial teeth to enhance gripping a workpiece in different directions. Pliers are provided with selectable mechanical advantages so that a user may select the mechanical advantage desirable for a particular application.

Abstract: A ratcheting tool is provided. The ratcheting tool includes a ratchet mechanism including a gear structure and a pawl structure. The pawl structure includes at least one elastic or integral component that provides spring action/biasing to the pawl teeth which facilitates ratcheting movement.

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 hand tool including a first jaw, a first handle fixed to the first jaw, a second jaw, and a second handle pivotally coupled to the second jaw. The hand tool further includes a link member having a first end pivotally coupled to at least one selected from the group of the first jaw and the first handle, and a second end pivotally coupled to the second jaw.

Abstract: A cutter comprises one or more blades, a hinge coupled to the blades, and one or more adjustable handles pivotally coupled to the hinge. When being adjusted, the one or more adjustable handles permit adjusting their positions with respect to the opposing handle without concurrently actuating the blades.

Abstract: A pipe wrench with an extendible handle is provided. The extendible handle may include a web and a flange to reduce bending stress. The pipe wrench may include a locking button that slides within a channel of the web to lock the extension handle at predetermined extended or retracted lengths. The locking button selectively enables the extension or retraction of the extension handle relative to the first handle of the pipe wrench. The locking button is biased by a spring and coupled to the extension handle with an e-clip. The body, the first handle, and/or the extension handle can include composite materials. In some embodiments, carbon fiber reinforced plastics, fiberglass reinforced plastics, and/or other reinforced polymers are used to form one or more features of the pipe wrench.

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: Pliers are provided. Pliers include an upper handle, a lower handle, an upper jaw coupled to the upper handle, and a lower jaw coupled to the lower handle. In general, the upper jaw includes workpiece engagement surface, such a first set of teeth configured to engage a workpiece, and the lower jaw includes a workpiece engagement surface, such as a second set of teeth and a third set of teeth. The lower jaw opposes the upper jaw such that the first set of teeth faces the second set of teeth and the third set of teeth. At least a section of the workpiece engagement surface of the lower jaw is movably coupled to the lower jaw such that it moves relative to the lower as torque is applied to a workpiece, thereby increasing torque applied to the workpiece.
