Abstract: The invention is directed broadly to a modular housing system having a structural framework comprising an internal chassis as a core structural element, the internal chassis including: a first ladder frame that defines a base; four columns at least two being extendable columns; and a second ladder frame engaged to the first ladder frame via the four columns, such that at least one of a distance and an angle between the first ladder frame and the second ladder frame is adjustable to define a usable volume of the structural framework.

Abstract: An apparatus for selectively removing material from both an inner and outer circumference of an end of a tubular workpiece includes a cylindrical outer frame. A blade holder is affixed to the outer frame. The blade holder has a conical configuration with a base located adjacent a first rim of the outer frame and an apex located adjacent a second rim of the outer frame. At least one ID blade is carried by the blade holder and has an ID cutting edge oriented radially outward. At least one OD blade is carried by the blade holder and has an OD cutting edge oriented radially inward. A motive cap has a rim-coupling feature configured for selective engagement sequentially with the first and second rims of the outer frame, to selectively provide rotational motion to the outer frame and thus indirectly to the blade holder.

Abstract: A pushbutton plier device and a method for converting a plier tool is provided. The pushbutton plier device includes a locking assembly. The locking assembly has a pushbutton and a housing. The pushbutton has a pushbutton body. The pushbutton body has at least one blocking member recess. The housing has a housing body. The housing body is configured to selectively contain a blocking member. The pushbutton plier device has a first plier handle and a second plier handle. The first plier handle has at least one first plier handle aperture. The second plier handle has at least one second plier handle aperture. When the first plier handle, the second plier handle, and the locking assembly are selectively joined together in a predetermined position, the locking assembly, located within the first plier handle aperture and the second plier aperture, secures the first plier handle to the second plier handle.

Abstract: A bending wheel of a tube bending apparatus includes a tube-accepting recess, proximal and distal wheel faces, and a rotation recess. The proximal wheel face includes a lever pivot anchor. A cam insert includes a shaft having a tool driving feature. The shaft is configured for selective insertion into the rotation recess. The cam insert includes a camming flange, which includes a lever urging feature. A keeper lever includes a keeper finger rigidly connected to a laterally extending lever arm and extending longitudinally from the proximal wheel face. An anchor end of the lever arm includes an arm pivot feature and a spaced-apart cam following feature configured to interact with the lever urging feature. Rotation of the cam insert causes rotation of the lever urging feature to drive the cam following feature of the keeper lever and pivot the lever arm in the same rotational direction.

Abstract: An adjustable insertion-depth tube flaring tool is provided. A selector housing is disposed on a yoke. An adjustment nut is disposed within the selector housing. An adjustment screw is disposed within at least one of the selector housing and the yoke. A clutch housing has therein at least one biasing element, at least one lower clutch plate, and at least one upper clutch plate. An upper clutch plate rotation supporting element interacts with a lower clutch plate rotation supporting element to facilitate rotation of the upper clutch plate over the lower clutch plate in one direction. At least a portion of a shaft proximal end and an upper clutch plate inner wall are shaped to interact with one another in such a manner that the upper clutch plate is selectively prevented from rotating about the shaft proximal end when the upper clutch plate is disposed on the shaft proximal end.
