Abstract: A modular assembly that is configured to be magnetically coupled to another object, such as a white board or glass board, is provided. The magnetic strength of the modular assembly can be adjusted. The modular assembly includes an article, such as a tray or other type of holder for receiving materials like markers and papers, and a module that houses magnets. The article can include a magnet housing portion with a magnet housing retention feature. The module can include a magnet housing with one or more magnets held therein. The magnet housing can include an article coupling feature. The module can slide into the magnet housing portion of the article and be secured in place by the engagement of the magnet housing retention feature and the article coupling feature.

Abstract: An eraser assembly is provided that includes a housing, a tray, a coupler, and an eraser insert. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion of the housing and a mounting portion disposed opposite the retaining portion. The coupler is configured to releasably hold the tray to the housing. The eraser insert is configured to be mounted to the mounting portion. An eraser insert is also provided that includes a first side and a second side, an eraser pad, and a coupler. The first side includes a mounting surface and an eraser pad is disposed on the second side. The coupler is disposed on or about the mounting surface and is configured to detachably connect the eraser insert to an eraser assembly at the mounting surface.

Abstract: An eraser assembly is provided that includes a housing, a tray, and a coupler disposed between a surface of the tray and a surface of the housing. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion and a mounting portion disposed opposite of the retaining portion. The coupler is configured to releasably hold the tray to the housing. An eraser insert configured to be disposed in the interior portion of the housing and to be enclosed by the tray.

Abstract: A clip is provided that is configured to secure an object therein. The clip includes a front portion having a first end, a second end opposite the first end, an inner surface, and an outer surface. The outer surface of the front portion is configured to face away from the object. The base portion has a first end, a second end opposite the first end, an inner surface, and an outer surface. The inner surface of the base portion is configured to face the inner surface of the front portion. The outer surface of the base portion is configured to face away from the outer surface of the front portion. The clip includes a connector coupling the front portion to the base portion such that the front portion is movable in two degrees of freedom relative to the base portion. At least one magnet is coupled to at least one of the front portion and the base portion. The at least one magnet urges the inner surface of the front portion and the inner surface of the base portion together.

Abstract: An apparatus for connecting a writing implement to a glassboard, whiteboard or the like has a housing adapted to be connected to a writing implement. The housing has a side surface with an opening formed therein and a recess extending from the opening into the housing. A magnet is disposed in the recess and has a first pole at the opening. The magnet provides a magnetic field in a direction away from the side surface of the housing. The apparatus enables a side periphery of a writing implement coupled with the apparatus to magnetically couple with the glassboard, whiteboard or the like in a predetermined orientation regardless of the initial orientation of approach of the writing implement even in the presence of a similarly magnetically self-supporting writing implement or object.
