A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.

A bodily fluid cleanup system is configured to be assembled, employed and subsequently disposed of to safely remove biohazardous material from an area. The system includes a disposable receptacle and a plurality of disposable modular components for assembling a plurality of disposable modular implements, all of which may be enclosed within a single package. The modular implements may include, but are not limited to, a wiper blade, a broom, a dustpan and/or a mop. The receptacle transitions between an open position and a closed position and in an embodiment includes a base, an integral cover, a molded bottom edge insert and a molded mounting member which all form an enclosure that functions to house various materials and the implements in a pre-usage configuration and to retain biohazardous material during a cleanup process.

Rotatable handles and related methods are disclosed herein. In one form, the handle has a clip member that fits around a cylindrical object and a handle. The clip member includes a track that guides rotation of the handle about a longitudinal axis of the cylindrical object. The handle includes an actuator that operates a braking member which comprises a braking surface that is movable into and out of contact with the track. When the braking surface is out of contact the track, the handle is movable relative to the track when permitting the handle to rotate about a longitudinal axis of the cylindrical object. Rotating the handle about the longitudinal axis of the handle operates the actuator, causing the braking surface to move into and out of contact with the track. Various methods are also disclosed herein with respect to the rotatable handle.

A hand tool includes a handle which is a hollow handle with a space defined therein. A connection portion has a slit defined in the first end thereof. The connection portion has two ribs extending inward from an inside of the second end thereof. The handle has a tubular portion extending from one end thereof. A protrusion extends outward from outside of the tubular portion. The tubular portion is inserted into the second end of the connection portion, and the ribs are engaged with the protrusion. A blade has a body and a toothed portion. The toothed portion is inserted into the slit of the connection portion. A cooling material is located in the space of the handle. The connection portion of the handle is connected to the toothed portion of the blade. The cooling material performs as a weight in the handle.

Presented here are toollessly releasable, interchangeable handles for hand tools and methods of use thereof. Hand tool users often experience discomfort and injury because hand tool handles are not well suited to each user's hands. In addition, different hand tools have different handles, so users that switch between hand tools often find a different level of comfort with different hand tools. The disclosed platform for interchangeable handles for hand tools allows a user to attach handles custom fitted to their hand to any corresponding hand tool, and likewise allows different users to share a hand tool by detaching the first user's handles and then attaching a second user's handles. Various embodiments for connecting interchangeable handles to hand tools are shown. Additionally, a fluid reservoir disposed within an interchangeable handle and locking mechanisms for keeping the interchangeable handles attached to the hand tool are disclosed.

A handle mounting structure includes a handle including a handle shaft with a sliding space defined in one side thereof and a mounting unit located at one end thereof, a locking mechanism including an insert plate slidably inserted into the sliding space and a torsion spring mounted in the sliding space and stopped between the handle and the insert plate to impart a pressure to the insert plate toward the outside of the sliding space, and a positioning device including a flat base pivotally coupled to the handle and a hook block located at a bottom side of the flat base. The handle can be fastened to a sliding box of a cabinet through locking mechanism and the positioning device, so that the handle is not easily separated from the sliding box, and the sliding box can be surely pulled out of or pushed into the cabinet through the handle.
