Superior usability is provided and the degree of freedom in terms of use is enhanced.

A plurality of link members A1 and A2 include at least one of linear edges A12 and A22 at the peripheral edge of a facing surface A10 or A20 that faces in a folded state. At least one of the adjacent link members A1 and A2 is a magnet, and the other is a material attracted by the magnet. A link body A is formed of the link members A1 and A2 that are linked by the attracting force due to the magnetic force of the link members A1 and A2, of which the linear edges A12 and A22 are aligned.

A frame assembly for displaying an object is described. In an embodiment, the frame assembly comprises a printable, rigid material forming a rectangular shaped outer frame that defines an area in which the object, such as a photograph, is displayed. The outer frame is made of a rigid, multilayer substrate that has been machined with grooves that allows it to be manipulated to form front and side walls, such that an image can be printed or wrapped around the entire surface. A method of making the frame assembly is also described. The method comprises printing an image on the frame, such as by direct digital or screen printing prior to assembling the parts of the frame.

A partition wall usable in any residential or work environment is described having modules that can be customized to create a partition wall that best suits the needs of the user. The modules that make up the partition wall can be made from a single frame structure or multiple frame components that connect together to form generally rectangular or square like modules or building blocks that form the partition wall. The modules can connect to any adjacent module on each side or top or bottom. The modules are assembled into the requisite number of rows and columns to form the partition wall at the desired width and height. The modules include electrical contacts to provide electrical power to one or more add on pieces that require power to function, including, fans and light panels. Further, sound batting can be added, and decorative panels to provide an aesthetically pleasing appearance.

A marker board system having a dark colored, low hardness, low surface energy solid silicone sheet to wet to a vertically oriented high surface energy substrate on a smooth, flat back-side of the solid silicone sheet. A front-side of the solid silicone sheet is able to be written upon by brightly colored marker ink. The brightly colored marker ink is able to be easily erased from the front-side of the solid silicone sheet after being written upon the front-side of the solid silicone sheet. The front-side is roughened to diminish beading of the brightly colored marker ink when written on the front-side.

A drawing device with a rotatable display screen is provided, having a housing having a cavity therein and a display screen sealingly rotatably coupled to the housing. An inner surface of the display screen forms an enclosure with the cavity. A powder is contained within the enclosure, the powder being removably adherent to the inner surface of the display screen. A first stylus controller is supported on an exterior of the housing. At least one positioning structure is supported in the enclosure and coupled to the first stylus controller to move a first stylus in a first set of directions that are parallel to a first axis. The first stylus removes the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

A magnetic pen can be used in drawing arbitrary characters, figures, and symbols on a magnetic panel for a display by applying a magnetic field. The magnetic pen includes a body that includes an end portion. A holder made of a magnetic material is attached to the end portion and an internal space is formed in the holder. The holder includes a bottom portion formed with an opening and a side portion connected to the bottom portion. A magnet is arranged in the internal space of the holder. The magnet is received in a space formed by the bottom portion and the side portion.

A cylindrical winding tool 3 has three elongated members 5 obtained by splitting a cylindrical member in its axial direction into multiple pieces. The elongated members are interconnected in a hinged state in a circumferential direction by the magnet sheet. When the elongated members 5 are to be used, the elongated members 5 are placed in a spread state and arranged on the magnetically-attached object 4. When the elongated members 5 are not used, the elongated members 5 are gathered together in the circumferential direction, abutment sections 5b of the end faces of the adjacent elongated members are brought into abutment on each other and thus the cylindrical winding tool 3 having a required diameter can be formed.

The preferred embodiment of the present invention comprises a stackable and modularly reconfigurable device and system providing a surface for marking and displaying items. More specifically, embodiments of the invention relate to a modularly reconfigurable device and system having erasable writing surfaces with interconnection features.
